Hello, and welcome to [[Wikiversity:Introduction|Wikiversity]]'s online [[W:Geometry|geometry]] course!
==Course Description==
A course in plane and solid geometry will investigate the basic concepts of [[W:Euclidean geometry|Euclidean geometry]]. Undefined terms and axioms will be presented and used to prove conjectures. The properties of two- and three-dimensional shapes will be explored. Students will also work with coordinate geometry, including transformations. The goal of this course is not only to master the facts of geometry necessary for advanced courses but also the techniques of deductive mathematical proofs as well.
==Curriculum==
One lesson should be learned every weekday.</br>

==Homework assignments==
Homework will be assigned after most class sessions at the bottom of the page. Homework will be emailed the day after you complete your assignment. Homework will be graded for completeness and correctness. A student can receive up to 3 points for a question. Two points will be awarded for attempting to solve a problem. A third of the assigned problems will be graded for correctness, with an additional point given for the correct answer. No credit will be given for problems not solved. Therefore, every problem should be attempted. As we are more interested in learning methods of solving problems than in answers, all work involved in solving a problem must be shown for credit to be received.
==Tests, quizzes, and exams==
===Tests===
Tests are given after every chapter and must be completed within 45 minutes. Tests are out of 100 points. To be granted access to the test. All homeworks must be handed in on time. Except for 2, if you wish
===Exams===
An exam is given half-way through the program and at the end. Exams are given 60 minutes to complete. Exams will be given after you complete half, and then all the tests.

Typing is the process of writing or inputting text by pressing keys on a typewriter, keyboard, cell phone, or a calculator. It can be distinguished from other means of text input, such as handwriting and speech recognition.<ref>[[Wikipedia: Typing]]</ref>
Learners should practice typing for fifteen minutes each day until their typing speed is at least 30 words per minute.

==Welcome==
Please make sure you have reviewed the page ''[[Wikiversity:What is Wikiversity?|What is Wikiversity?]]'' before you participate and contribute to this project.
==What are ethics?==
Ethics are moral standards of conduct agreed upon to define right and wrong. That which is ethical is considered morally correct. That which is unethical is considered morally wrong. Ethics are usually considered in a professional code of conduct as a qualified professional is under more expection than an unqualified individual to have a learned understanding of the accepted principles of right and wrong.
== Learning ethics in online media ==
{{Disclosures}}
Principles of [[ethics]] in online media is the scope for this resource; however, this resource draws upon comparisons that center on the English Wikipedia, which has over a quarter-million biographies of living persons (BLPs) as well as many articles that characterize people, organizations, events, and other aspects of human activity. The degree to which the content and practices of Wikimedia projects adhere to commonly recognized principles of ethics, which include such comparisons of Wikipedia, are what this resource examines.
Temporary guideline: This project currently does not accept case studies of living people until further notice.

Psychopathy has a polygenic basis, with six [[genes]] having been shown particular significance regarding the risk: ANKK1, [[DRD2]], DRD4, [[COMT]], MAOA, and SLC6A4 (particularly the 5-HTTLPR variant). Other notable genetic risk factors for becoming a psychopath include [[alleles]] of OXTR, AVPR1A, CADM2, PRKG1, and NR3C1. Several of these genes, like COMT, MAOA, 5-HTTLPR, OXTR, and NR3C1, undergo direct epigenetic modification following trauma. Psychopathy is principally a personality construct used by psychologists to explain and predict behavior, but may also be described as an epigenetic condition that affects the trajectory of neurodevelopment.
The expression of psychopathy-related phenotypes depends on the combination of inherited alleles, in addition to environmental factors. Individuals are at an elevated risk of psychopathic traits if they inherit multiple core alleles located at different [[loci]], likely at least four core alleles at a minimum of three different loci. This is similar to many other spectrum disorders, such as schizotypy, which typically involve a complex interaction between genes and environmental factors.

== DRD2 ==
In addition to the DRD2 957C/C genotype, the DRD2 Taq1 B allele and polymorphisms in the promoter region of the DRD4 gene have also have been linked to psychopathy. This suggests that the dissocial and impulsive basal endophenotypes can be subdivided into at least seven subtypes: 1a, 1b, 1c, 2, 3a, 3b, and 3c.

Psychopathy has a polygenic basis, with six [[genes]] having been shown particular significance regarding the risk: ANKK1, [[DRD2]], DRD4, [[COMT]], MAOA, and SLC6A4 (particularly the 5-HTTLPR variant). Other notable genetic risk factors for becoming a psychopath include [[alleles]] of OXTR, AVPR1A, CADM2, PRKG1, and NR3C1. Several of these genes, like COMT, MAOA, 5-HTTLPR, OXTR, and NR3C1, undergo direct epigenetic modification following trauma. Psychopathy is principally a personality construct used by psychologists to explain and predict behavior, but may also be described as a condition that affects the trajectory of neurodevelopment.
The expression of psychopathy-related phenotypes depends on the combination of inherited alleles, in addition to environmental factors. Individuals are at an elevated risk of psychopathic traits if they inherit multiple core alleles located at different [[loci]], likely at least four core alleles at a minimum of three different loci. This is similar to many other spectrum disorders, such as schizotypy, which typically involve a complex interaction between genes and environmental factors.

In addition to the DRD2 957C/C genotype, the DRD2 Taq1 B allele and polymorphisms in the promoter region of the DRD4 gene have also have been linked to psychopathy. This suggests that the dissocial and impulsive basal endophenotypes can be subdivided into at least seven subtypes: 1a, 1b, 1c, 2, 3a, 3b, and 3c.

Given any collection of real numbers, an '''average''' is a single number intended to give an estimate of the general magnitude of the numbers. Formally, it is a function from a set of ''n'' numbers to a single number with the following properties:
# If all the numbers are equal, their average should also equal this value: AV(x, x, x, ...) = x.
# The average must not exceed the maximum of the numbers nor be less than their minimum. We may wish to be stricter and say that if not all the numbers are equal, it must be greater than the minimum and less than the maximum, but this would rule out the ''median'' as an average, since the median of say (1,1,1,1,2) is 1.
# The average must be multiplicatively linear, i.e. if all numbers are multiplied by the same constant ''k'' their average will be multiplied by the same number: AV(kx, ky) = k.AV(x, y).
# The average must be order invariant; if we permute the numbers, it will not change their average: AV(y, x) = AV(x, y). This rules out just picking the first number, or the average of the first and last, or other weighted averages.
# The average must be monotonic; if any one number increases (the others being unchanged), the average must not decrease, and vice versa. This rules out some "robust measures", where outliers are rejected before the average is taken. We may wish to be stricter and say that if any number increases, so must the average. Again, this would rule out the median as an average, since the median of say (1,1,1,1,2) and (1,1,1,2,2) are both 1.
It might be supposed that the average should be translation invariant, so that if all numbers are increased by the same constant ''k'' their average will increase by the same number: AV(x+k,y+k) = AV(x,y)+k. However, it can be shown that there is only one average meeting this and the other requirements strictly: the arithmetic mean discussed below. If the less strict versions of the requirements are used, the median and other quartiles would meet all the requirements.
It might also be supposed that the average should be a continuous function of the numbers. Again, this would rule out quartiles.
== The arithmetic mean ==
The simplest average is the ''arithmetic mean'', defined as the sum of the numbers divided by the number of numbers. Thus the average of {1,2,3,4,5) is (1+2+3+4+5)/5 = 3.
''Exercise:'' Verify that this meets all the conditions above, including the stricter versions.
== The geometric mean ==
Another common average is the ''geometric mean'', obtained by multiplying all the numbers together and, if there are ''n'' numbers, taking the ''nth'' root. Thus the geometric mean of {1,2,3,4,5) is (1x2x3x4x5)<sup>1/5</sup> = 2.605 (approximately).
Note that the geometric mean should not be used if any of the numbers is negative (why?) and is zero if any of the numbers is zero, no matter how large the other numbers are (why?).
''Exercise:'' Verify that the geometric mean meets all the conditions above, including the stricter versions.
== The arithmetic/geometric inequality ==
Unless all the numbers are equal, the geometric mean is always less than the arithmetic mean.
This is easily proved for just two numbers and three numbers; the outlines of the proof are:
If ''a'' and ''b'' are two unequal non-negative numbers, then
:<math>\displaystyle(\sqrt a-\sqrt b)^2 > 0</math>
This can be rearranged as
:<math>\displaystyle \frac{a+b}{2} > \sqrt(a \times b)</math>
If ''a'', ''b'' and ''c'' are three non-negative numbers, not all equal, then
:<math>\displaystyle (a^{1/3} - b^{1/3})^2 + (b^{1/3} - c^{1/3})^2 + (c^{1/3} - a^{1/3})^2 > 0</math>
So
:<math>\displaystyle [(a^{1/3} - b^{1/3})^2 + (b^{1/3} - c^{1/3})^2 + (c^{1/3} - a^{1/3})^2] \times [a^{1/3} + b^{1/3} + c^{1/3}] > 0</math>
This can be rearranged as
:<math>\displaystyle \frac{a+b+c}{3} > (a \times b \times c)^{1/3}</math>
For four numbers, take the numbers in pairs and apply the already proven result for two numbers.
== Quantifying the arithmetic/geometric inequality ==
How can we assess whether the geometric mean is close to the arithmetic mean, or substantially less?
Given a set of n numbers {x<sub>1</sub> ... x<sub>n</sub>}, let their arithmetic mean be m and
:<math>\displaystyle y_i = \frac{x_i}{m}-1</math> so <math>\displaystyle x_i = m(1+y_i).</math>
Then the sum of the y<sub>i</sub> is zero. (Why?) We assume that the x<sub>i</sub> do not diverge too much from their mean, so the y<sub>i</sub> are fairly small numbers and we can expand log (1+y) in a power series.
:<math>\displaystyle \frac{GM}{AM} = {{\prod m(1+y_i)}^{1/n} \over m} = {\prod (1+y_i)}^{1/n}.</math>
:<math>\displaystyle \log \left( \frac{GM}{AM} \right) = \frac{1}{n} \sum log(1+y_i) \approx \frac{1}{n} \sum (y_i - \frac{1}{2} y_i^2) = - \frac{1}{2} \frac{1}{n}y_i^2</math> (since Σ y<sub>i</sub> is zero). Thus
:<math>\displaystyle \frac{GM}{AM} \approx 1 - \frac{1}{2} \frac{1}{n}y_i^2.</math> (Why?)
In other words, the greater the dispersion of the numbers about their arithmetic mean, the greater the difference between the two means.
''Exercise:'' Some approximations have been made in deriving this result. Demonstrate by actual calculations that the result is true in general.
== Root mean square ==
The '''RMS''' is the square root of the arithmetic mean of the squares of a collection of numbers, i.e.
:<math>\displaystyle RMS(x_1 ... x_n) = \sqrt { \frac{1}{n} \Sigma x_i^2 } </math>
This average should not be used for a mixture of positive and negative numbers (why?).
''Exercise:'' Verify that this meets all the conditions above, including the stricter versions.
Unless all the numbers are equal, the RMS is always greater than the arithmetic mean. This is easily proved for just two numbers by considering the square of the RMS and of the arithmetic mean:
:<math>\displaystyle \frac{x^2+y^2}{2} - \left ( \frac{x+y}{2} \right )^2 = \frac{1}{4} (2x^2+2y^2-x^2-2xy-y^2) = \frac{1}{4} (x^2+y^2-2xy) = \frac{1}{4} (x-y)^2 > 0</math>
A similar but more complex proof will work for any number of numbers. With a slight extension of the proof, it may be shown that if ''m'' is the arithmetic mean and ''s''<sup>2</sup> is the variance of a set of numbers, then <math>RMS = \sqrt (m^2 + s^2).</math>
== Harmonic mean ==
The '''harmonic mean''' of a set of numbers is the reciprocal of the arithmetic mean of the reciprocals of those numbers. Thus for three numbers we have
:<math>\displaystyle harmonic \,\, mean(x,y,z) = \frac{3}{\frac{1}{x}+\frac{1}{y}+\frac{1}{z}}</math>
This mean should not be used if any number is zero or negative (why?).
''Exercise:'' Verify that this meets all the conditions above, including the stricter versions.
Unless all the numbers are equal, the harmonic is always less than the geometric mean. This follows because its reciprocal is the arithmetic mean of the reciprocals of the numbers, hence is greater than the geometric mean of the reciprocals which is the reciprocal of the geometric mean. Thus we have:
: harmonic mean < geometric mean < arithmetic mean < RMS.
== Rth power mean ==
The '''rth power mean''' of a set of numbers, for any real number r, is
:<math>\displaystyle mean(x_1 ... x_n) = \left ( \frac{1}{n} \Sigma x_i^r \right )^\frac{1}{r} </math>
This average should only be used for positive numbers if r < 0 and non-negative numbers if r > 0 (why?).
''Exercise:'' Verify that this meets all the conditions above, including the stricter versions.
This mean is undefined for r = 0, but the limit as r tends to 0 is the geometric mean. Thus all of the averages we have considered so far are special cases of this mean (r = -1, harmonic; r = 0, geometric; r = 1, arithmetic; r = 2, RMS).
It can be shown that for any collection of positive numbers (not all equal), this mean is a continuous, strictly monotonic increasing function of r; the inequalities above are special cases of this. As r tends to infinity, the mean tends to the maximum of the x<sub>i</sub>, and as r tends to minus infinity, the mean tends to the minimum of the x<sub>i</sub>.
== Power plus 1 mean ==
The '''power plus 1 mean''' of a set of numbers, for any real number s, is
:<math>\displaystyle mean(x_1 ... x_n) = \frac{\Sigma x_i^{s+1}}{\Sigma x_i^s}</math>
If s=0, this is the arithmetic mean; if s=-1 it is the harmonic mean.
Note in particular that if s=1, this is RMS<sup>2</sup>/(arithmetic mean). If ''m'' is the arithmetic mean and ''s''<sup>2</sup> is the variance of a set of numbers, than the s=1 mean is
:<math>{{m^2+s^2} \over m} = m(1+\frac{s^2}{m^2}) > m</math>
It can be shown that this type of mean behaves much like the rth power mean. For any collection of positive numbers (not all equal), this mean is a continuous, strictly monotonic increasing function of s. As s tends to infinity, the mean tends to the maximum of the x<sub>i</sub>, and as s tends to minus infinity, the mean tends to the minimum of the x<sub>i</sub>.
Both of these types of mean can be regarded as a special case of the following:
:<math>\displaystyle mean(x_1 ... x_n) = \left( \frac{\Sigma x_i^{s+r}}{\Sigma x_i^s} \right)^{1/r}</math>
Clearly, if s=0 this is the forth power mean; if r=1 this is the power plus 1 mean.
== Mixed averages ==
More types of average can be found by mixing different averages, provided that the formula is symmetric in the variables. For example, for any three numbers x, y, z, the following are all averages:
:<math>\frac{1}{3}(\sqrt(xy) + \sqrt(yz) + \sqrt(zx))</math>
:<math>\sqrt ( \frac{1}{3}(xy + yz + zx) )</math>
:<math>\frac{1}{2}((x+y)(y+z)(z+x))^{1/3}</math>
== The median and other quartiles As noted above, the median is an average if we do not require some strict inequalities in the definition. In fact, this is true of any quartile of the distribution, even maximum and minimum. It may seem perverse to call the maximum and minimum "averages". However, the fundamental purpose of an average is to give an estimate of the order of magnitude of a group of numbers. If the range of numbers is small, the maximum and minimum can do this; if the range is very large, any one number as the average may be misleading. As noted above, the maximum and minimum are limiting values of other averages as parameters tend to infinity. ==
It may be argued that any quartile other than the median is "biased" hence unsatisfactory. However, if in a group of numbers a few of them are much larger or much smaller than the others ("outliers"), any average may seem biased. For example, consider {1,2,3,4,5,6,7,8,144}. The arithmetic mean is 20, far higher than the ''upper quartile'' of 7 and indeed far higher than all but one of the numbers.
== The mode ==
The mode is not an average. Firstly, it is not always uniquely defined; for example, in {1,1,1,2,2,3,3,3} there are two modes, 1 and 3 (which are also the minimum and maximum). Secondly and more important, it does not satisfy the monotonicity rule. Consider the set of eight numbers
:{1,1,1,2,2,2,2,3}
The mode is 2. Now suppose the seventh number increases from 2 to 3:
:{1,1,1,2,2,2,3,3}
The joint modes are now 1 and 2. Now suppose the sixth number increases from 2 to 4:
:{1,1,1,2,2,3,3,4}
The mode is now 1.
== Transformation means ==
Let f(x) be any strictly monotonic function. Given a set of numbers {x<sub>1</sub> ... x<sub>n</sub>}, define:
# y<sub>i</sub> = f(x<sub>i</sub>)
# Y as the arithmetic mean of the y<sub>i</sub>
# X as the solution of the equation Y = f(X).
X is then the ''transformation mean'' of the x<sub>i</sub> with respect to f(x).
''Examples:'' f(x) = x<sup>r</sup> gives the rth power mean; f(x) = log(x) gives the geometric mean.
''Exercises''
# Will such a mean always obey the conditions at the beginning of the article?
# Would using a different sort of mean at step 2, e.g. the geometric mean, give yet another sort of average?
# Why does the equation in step 3 always have one and only one solution? Does it matter if f(x) is not continuous?
# Find a function f(x) such that the transformation mean equals the median.

Given any collection of real numbers, an '''average''' is a single number intended to give an estimate of the general magnitude of the numbers. Formally, it is a function from a set of ''n'' numbers to a single number with the following properties:
# If all the numbers are equal, their average should also equal this value: AV(x, x, x, ...) = x.
# The average must not exceed the maximum of the numbers nor be less than their minimum. We may wish to be stricter and say that if not all the numbers are equal, it must be greater than the minimum and less than the maximum, but this would rule out the ''median'' as an average, since the median of say (1,1,1,1,2) is 1.
# The average must be multiplicatively linear, i.e. if all numbers are multiplied by the same constant ''k'' their average will be multiplied by the same number: AV(kx, ky) = k.AV(x, y).
# The average must be order invariant; if we permute the numbers, it will not change their average: AV(y, x) = AV(x, y). This rules out just picking the first number, or the average of the first and last, or other weighted averages.
# The average must be monotonic; if any one number increases (the others being unchanged), the average must not decrease, and vice versa. This rules out some "robust measures", where outliers are rejected before the average is taken. We may wish to be stricter and say that if any number increases, so must the average. Again, this would rule out the median as an average, since the median of say (1,1,1,1,2) and (1,1,1,2,2) are both 1.
It might be supposed that the average should be translation invariant, so that if all numbers are increased by the same constant ''k'' their average will increase by the same number: AV(x+k,y+k) = AV(x,y)+k. However, it can be shown that there is only one average meeting this and the other requirements strictly: the arithmetic mean discussed below. If the less strict versions of the requirements are used, the median and other quartiles would meet all the requirements.
It might also be supposed that the average should be a continuous function of the numbers. Again, this would rule out quartiles.
== The arithmetic mean ==
The simplest average is the ''arithmetic mean'', defined as the sum of the numbers divided by the number of numbers. Thus the average of {1,2,3,4,5) is (1+2+3+4+5)/5 = 3.
''Exercise:'' Verify that this meets all the conditions above, including the stricter versions.
== The geometric mean ==
Another common average is the ''geometric mean'', obtained by multiplying all the numbers together and, if there are ''n'' numbers, taking the ''nth'' root. Thus the geometric mean of {1,2,3,4,5) is (1x2x3x4x5)<sup>1/5</sup> = 2.605 (approximately).
Note that the geometric mean should not be used if any of the numbers is negative (why?) and is zero if any of the numbers is zero, no matter how large the other numbers are (why?).
''Exercise:'' Verify that the geometric mean meets all the conditions above, including the stricter versions.
== The arithmetic/geometric inequality ==
Unless all the numbers are equal, the geometric mean is always less than the arithmetic mean.
This is easily proved for just two numbers and three numbers; the outlines of the proof are:
If ''a'' and ''b'' are two unequal non-negative numbers, then
:<math>\displaystyle(\sqrt a-\sqrt b)^2 > 0</math>
This can be rearranged as
:<math>\displaystyle \frac{a+b}{2} > \sqrt(a \times b)</math>
If ''a'', ''b'' and ''c'' are three non-negative numbers, not all equal, then
:<math>\displaystyle (a^{1/3} - b^{1/3})^2 + (b^{1/3} - c^{1/3})^2 + (c^{1/3} - a^{1/3})^2 > 0</math>
So
:<math>\displaystyle [(a^{1/3} - b^{1/3})^2 + (b^{1/3} - c^{1/3})^2 + (c^{1/3} - a^{1/3})^2] \times [a^{1/3} + b^{1/3} + c^{1/3}] > 0</math>
This can be rearranged as
:<math>\displaystyle \frac{a+b+c}{3} > (a \times b \times c)^{1/3}</math>
For four numbers, take the numbers in pairs and apply the already proven result for two numbers.
== Quantifying the arithmetic/geometric inequality ==
How can we assess whether the geometric mean is close to the arithmetic mean, or substantially less?
Given a set of n numbers {x<sub>1</sub> ... x<sub>n</sub>}, let their arithmetic mean be m and
:<math>\displaystyle y_i = \frac{x_i}{m}-1</math> so <math>\displaystyle x_i = m(1+y_i).</math>
Then the sum of the y<sub>i</sub> is zero. (Why?) We assume that the x<sub>i</sub> do not diverge too much from their mean, so the y<sub>i</sub> are fairly small numbers and we can expand log (1+y) in a power series.
:<math>\displaystyle \frac{GM}{AM} = {{\prod m(1+y_i)}^{1/n} \over m} = {\prod (1+y_i)}^{1/n}.</math>
:<math>\displaystyle \log \left( \frac{GM}{AM} \right) = \frac{1}{n} \sum log(1+y_i) \approx \frac{1}{n} \sum (y_i - \frac{1}{2} y_i^2) = - \frac{1}{2} \frac{1}{n}y_i^2</math> (since Σ y<sub>i</sub> is zero). Thus
:<math>\displaystyle \frac{GM}{AM} \approx 1 - \frac{1}{2} \frac{1}{n}y_i^2.</math> (Why?)
In other words, the greater the dispersion of the numbers about their arithmetic mean, the greater the difference between the two means.
''Exercise:'' Some approximations have been made in deriving this result. Demonstrate by actual calculations that the result is true in general.
== Root mean square ==
The '''RMS''' is the square root of the arithmetic mean of the squares of a collection of numbers, i.e.
:<math>\displaystyle RMS(x_1 ... x_n) = \sqrt { \frac{1}{n} \Sigma x_i^2 } </math>
This average should not be used for a mixture of positive and negative numbers (why?).
''Exercise:'' Verify that this meets all the conditions above, including the stricter versions.
Unless all the numbers are equal, the RMS is always greater than the arithmetic mean. This is easily proved for just two numbers by considering the square of the RMS and of the arithmetic mean:
:<math>\displaystyle \frac{x^2+y^2}{2} - \left ( \frac{x+y}{2} \right )^2 = \frac{1}{4} (2x^2+2y^2-x^2-2xy-y^2) = \frac{1}{4} (x^2+y^2-2xy) = \frac{1}{4} (x-y)^2 > 0</math>
A similar but more complex proof will work for any number of numbers. With a slight extension of the proof, it may be shown that if ''m'' is the arithmetic mean and ''s''<sup>2</sup> is the variance of a set of numbers, then <math>RMS = \sqrt (m^2 + s^2).</math>
== Harmonic mean ==
The '''harmonic mean''' of a set of numbers is the reciprocal of the arithmetic mean of the reciprocals of those numbers. Thus for three numbers we have
:<math>\displaystyle harmonic \,\, mean(x,y,z) = \frac{3}{\frac{1}{x}+\frac{1}{y}+\frac{1}{z}}</math>
This mean should not be used if any number is zero or negative (why?).
''Exercise:'' Verify that this meets all the conditions above, including the stricter versions.
Unless all the numbers are equal, the harmonic is always less than the geometric mean. This follows because its reciprocal is the arithmetic mean of the reciprocals of the numbers, hence is greater than the geometric mean of the reciprocals which is the reciprocal of the geometric mean. Thus we have:
: harmonic mean < geometric mean < arithmetic mean < RMS.
== Rth power mean ==
The '''rth power mean''' of a set of numbers, for any real number r, is
:<math>\displaystyle mean(x_1 ... x_n) = \left ( \frac{1}{n} \Sigma x_i^r \right )^\frac{1}{r} </math>
This average should only be used for positive numbers if r < 0 and non-negative numbers if r > 0 (why?).
''Exercise:'' Verify that this meets all the conditions above, including the stricter versions.
This mean is undefined for r = 0, but the limit as r tends to 0 is the geometric mean. Thus all of the averages we have considered so far are special cases of this mean (r = -1, harmonic; r = 0, geometric; r = 1, arithmetic; r = 2, RMS).
It can be shown that for any collection of positive numbers (not all equal), this mean is a continuous, strictly monotonic increasing function of r; the inequalities above are special cases of this. As r tends to infinity, the mean tends to the maximum of the x<sub>i</sub>, and as r tends to minus infinity, the mean tends to the minimum of the x<sub>i</sub>.
== Power plus 1 mean ==
The '''power plus 1 mean''' of a set of numbers, for any real number s, is
:<math>\displaystyle mean(x_1 ... x_n) = \frac{\Sigma x_i^{s+1}}{\Sigma x_i^s}</math>
If s=0, this is the arithmetic mean; if s=-1 it is the harmonic mean.
Note in particular that if s=1, this is RMS<sup>2</sup>/(arithmetic mean). If ''m'' is the arithmetic mean and ''s''<sup>2</sup> is the variance of a set of numbers, than the s=1 mean is
:<math>{{m^2+s^2} \over m} = m(1+\frac{s^2}{m^2}) > m</math>
It can be shown that this type of mean behaves much like the rth power mean. For any collection of positive numbers (not all equal), this mean is a continuous, strictly monotonic increasing function of s. As s tends to infinity, the mean tends to the maximum of the x<sub>i</sub>, and as s tends to minus infinity, the mean tends to the minimum of the x<sub>i</sub>.
Both of these types of mean can be regarded as a special case of the following:
:<math>\displaystyle mean(x_1 ... x_n) = \left( \frac{\Sigma x_i^{s+r}}{\Sigma x_i^s} \right)^{1/r}</math>
Clearly, if s=0 this is the forth power mean; if r=1 this is the power plus 1 mean.
== Mixed averages ==
More types of average can be found by mixing different averages, provided that the formula is symmetric in the variables. For example, for any three numbers x, y, z, the following are all averages:
:<math>\frac{1}{3}(\sqrt(xy) + \sqrt(yz) + \sqrt(zx))</math>
:<math>\sqrt ( \frac{1}{3}(xy + yz + zx) )</math>
:<math>\frac{1}{2}((x+y)(y+z)(z+x))^{1/3}</math>
== The median and other quartiles As noted above, the median is an average if we do not require some strict inequalities in the definition. In fact, this is true of any quartile of the distribution, even maximum and minimum. It may seem perverse to call the maximum and minimum "averages". However, the fundamental purpose of an average is to give an estimate of the order of magnitude of a group of numbers. If the range of numbers is small, the maximum and minimum can do this; if the range is very large, any one number as the average may be misleading. As noted above, the maximum and minimum are limiting values of other averages as parameters tend to infinity. ==
It may be argued that any quartile other than the median is "biased" hence unsatisfactory. However, if in a group of numbers a few of them are much larger or much smaller than the others ("outliers"), any average may seem biased. For example, consider {1,2,3,4,5,6,7,8,144}. The arithmetic mean is 20, far higher than the ''upper quartile'' of 7 and indeed far higher than all but one of the numbers.
== The mode ==
The mode is not an average. Firstly, it is not always uniquely defined; for example, in {1,1,1,2,2,3,3,3} there are two modes, 1 and 3 (which are also the minimum and maximum). Secondly and more important, it does not satisfy the monotonicity rule. Consider the set of eight numbers
:{1,1,1,2,2,2,2,3}
The mode is 2. Now suppose the seventh number increases from 2 to 3:
:{1,1,1,2,2,2,3,3}
The joint modes are now 1 and 2. Now suppose the sixth number increases from 2 to 4:
:{1,1,1,2,2,3,3,4}
The mode is now 1.
== Transformation means ==
Let f(x) be any strictly monotonic function. Given a set of numbers {x<sub>1</sub> ... x<sub>n</sub>}, define:
# y<sub>i</sub> = f(x<sub>i</sub>)
# Y as the arithmetic mean of the y<sub>i</sub>
# X as the solution of the equation Y = f(X).
X is then the ''transformation mean'' of the x<sub>i</sub> with respect to f(x).
''Examples:'' f(x) = x<sup>r</sup> gives the rth power mean; f(x) = log(x) gives the geometric mean.
''Exercises''
# Will such a mean always obey the conditions at the beginning of the article?
# Would using a different sort of mean at step 2, e.g. the geometric mean, give yet another sort of average?
# Why does the equation in step 3 always have one and only one solution? Does it matter if f(x) is not continuous?
# Find a function f(x) such that the transformation mean equals the median.

The Impact of Emotional Intelligence on Leadership Effectiveness and Employee Engagement: A Critical Review
Abstract
The significance of Emotional Intelligence (EI) in contemporary organizational environments has become increasingly apparent, particularly concerning its influence on leadership effectiveness and employee engagement. As organizations confront complex demands in an era defined by rapid technological change, globalization, and diverse workforce dynamics, emotionally intelligent leadership is now recognized as an indispensable driver of success. This critical review investigates how EI contributes to leadership capabilities, examining its role in shaping interpersonal relationships, decision-making, conflict management, and motivational strategies. Simultaneously, it explores how emotionally intelligent leaders enhance employee engagement by creating psychologically safe, supportive, and empathetic work environments. Drawing on a wide range of theoretical frameworks and empirical findings from the last three decades, the review highlights both the transformative potential and the limitations of EI in leadership practice. Methodological issues in measurement and cross-cultural applicability are also critically evaluated. The review concludes by identifying key research gaps and offering recommendations for future inquiry, including the need for longitudinal studies, culturally sensitive EI instruments, and more nuanced training interventions.

Introduction
In the evolving ecosystem of modern organizations, the competencies that define effective leadership are undergoing a profound transformation. Traditional models of leadership, which once prioritized strategic vision, technical expertise, and task delegation, are increasingly being supplemented—and in some contexts, supplanted—by a growing emphasis on interpersonal acumen, emotional awareness, and relational trust. Central to this shift is the concept of Emotional Intelligence (EI), a multidimensional construct that encompasses the capacity to perceive, understand, regulate, and effectively use emotions in both intrapersonal and interpersonal contexts.
As early as the mid-1990s, scholars such as Daniel Goleman (1995) began to popularize the idea that emotional competencies may be more predictive of workplace success than intellectual ability alone. Subsequent research has bolstered these claims, suggesting that emotionally intelligent leadership not only enhances team performance but also significantly impacts the degree to which employees feel connected, motivated, and committed to their work (Carmeli, 2003; Wong & Law, 2002). In parallel, the concept of employee engagement—defined as the extent to which individuals bring their full selves to their roles—has emerged as a vital indicator of organizational health and productivity (Kahn, 1990; Schaufeli et al., 2002).
This review aims to explore the intersection between emotional intelligence, leadership effectiveness, and employee engagement through a critical synthesis of literature spanning psychology, management, and organizational behavior. The guiding question is: How and to what extent does emotional intelligence shape leadership effectiveness and foster employee engagement in diverse organizational settings?
The paper proceeds in five sections. Following this introduction, Section 2 outlines the methodology used to select and analyze relevant literature. Section 3 presents an integrative discussion of findings, organized around core thematic axes. Section 4 synthesizes insights, identifies critical limitations, and suggests directions for future research. Section 5 concludes with a summary of implications for leadership practice and human resource development.
Methodology
To ensure comprehensive and systematic coverage of the existing body of research, this review adopted an integrative literature review approach, combining empirical studies, theoretical frameworks, and conceptual models from multidisciplinary sources. The following steps guided the review process:
2.1 Literature Search Strategy
A comprehensive search was conducted using the following academic databases:
• Scopus
• Web of Science
• PsycINFO
• JSTOR
• Google Scholar
Search strings included combinations of the following terms:
• “Emotional Intelligence” AND “Leadership Effectiveness”
• “EI” AND “Employee Engagement”
• “Emotionally Intelligent Leadership”
• “Transformational Leadership” AND “Emotions”
• “Workplace Emotions” AND “Motivation”
The time frame of the search spanned from 1990 to 2025, capturing foundational texts as well as the most recent scholarly contributions.
2.2 Inclusion and Exclusion Criteria
Inclusion Criteria:
• Peer-reviewed journal articles and meta-analyses
• Theoretical and conceptual papers with robust EI frameworks
• Empirical studies with clear methodology linking EI to leadership or engagement
• English-language publications
Exclusion Criteria:
• Grey literature, dissertations, and editorials
• Non-peer-reviewed conference papers
• Articles conflating EI with unrelated constructs such as charisma or extroversion without clear differentiation
2.3 Data Analysis and Synthesis
A total of 142 studies were initially identified. After removing duplicates and non-relevant studies, 87 high-quality sources were included in the final review. The selected studies were thematically coded into the following categories:
1. Definitions and theoretical models of EI
2. EI and leadership styles
3. EI and employee engagement
4. Measurement and methodological challenges
5. Organizational outcomes mediated by EI
Findings were synthesized using a qualitative, thematic analysis to identify recurrent patterns, theoretical convergences, and gaps in existing knowledge.
Discussion
3.1 Emotional Intelligence and Leadership Effectiveness
Leadership in emotionally charged environments—characterized by tight deadlines, high ambiguity, and team diversity—requires not only cognitive intelligence but emotional literacy. Leaders with high EI are better equipped to perceive the emotional undercurrents of their team, anticipate tension, and respond with empathy and composure (George, 2000). They tend to build stronger interpersonal bonds, communicate more effectively, and manage conflict with tact.
Transformational leadership theory aligns closely with EI principles. Bass and Riggio (2006) argue that transformational leaders must possess the emotional skills to inspire, motivate, and consider the individualized needs of followers. Studies show that emotionally intelligent leaders are more likely to exhibit transformational behaviors such as inspirational motivation and individualized consideration (Barling et al., 2000).
Goleman’s five domains of EI—self-awareness, self-regulation, motivation, empathy, and social skills—serve as a practical framework for assessing leadership competence. For example:
• Self-awareness enables a leader to recognize personal triggers and avoid reactive decision-making.
• Empathy fosters inclusive decision-making, encouraging diverse voices and psychological safety.
• Social skills help leaders resolve disputes, deliver feedback constructively, and foster collaboration.
Numerous empirical studies affirm the correlation between EI and leadership outcomes. Côté and Miners (2006) found that leaders with high EI consistently outperform peers in relationship management, conflict resolution, and team productivity. Moreover, EI has been linked with ethical leadership, a crucial dimension in today’s transparency-focused corporate climate (Brown & Treviño, 2006).
3.2 EI as a Catalyst for Employee Engagement
Emotionally intelligent leadership does not exist in a vacuum—it manifests in how employees perceive, react to, and engage with their work environments. Employee engagement is not solely a function of task design or compensation; it is deeply rooted in emotional connectedness to the workplace and to leadership.
Kahn’s (1990) psychological conditions for engagement—meaningfulness, safety, and availability—are all enhanced by emotionally intelligent leaders. These leaders create a culture where individuals feel seen, heard, and valued, thereby fostering intrinsic motivation. Macey and Schneider (2008) posit that emotionally resonant leadership directly correlates with employee enthusiasm, loyalty, and discretionary effort.
Leaders who practice emotional attunement and transparency are more likely to develop relational trust, which in turn encourages higher engagement levels. In distributed or virtual teams, where emotional cues are often muted, leaders with EI are better able to maintain cohesion and morale by adapting communication and offering empathy.
3.3 Mediating Variables and Organizational Outcomes
EI does not operate in isolation. Its impact on leadership and engagement is often mediated by variables such as:
• Organizational Culture: A culture that values emotional openness amplifies the effectiveness of EI.
• Psychological Safety: EI fosters environments where employees are unafraid to voice concerns or innovate.
• Emotional Labor: Leaders with EI manage the emotional display rules of organizations more authentically, reducing burnout (Grandey, 2000).
Furthermore, EI is positively associated with organizational citizenship behavior (OCB), lower turnover intent, and increased job satisfaction (Carmeli, 2003; Law et al., 2004).
3.4 Methodological Challenges and Critiques
Despite its popularity, EI research is not without controversy. Key critiques include:
• Measurement Variability: The use of self-report instruments like the EQ-i (Bar-On) or mixed models has led to inconsistent findings due to social desirability bias.
• Construct Validity: Some scholars argue that EI overlaps with personality traits, making it difficult to isolate its effects (Landy, 2005).
• Cultural Bias: Most EI assessments are developed in Western contexts, limiting cross-cultural applicability (Matsumoto, 2006).
• Causality vs. Correlation: Much of the EI literature is correlational, with limited longitudinal evidence to establish causal relationships.
Addressing these challenges requires more rigorous experimental designs, cross-cultural adaptations of EI tools, and longitudinal studies tracking leadership development over time.
Conclusion
This critical review has explored the compelling connections between emotional intelligence, leadership effectiveness, and employee engagement. The weight of scholarly evidence indicates that emotionally intelligent leaders create more empathetic, cohesive, and engaged workplaces. They inspire trust, mediate conflict constructively, and align emotional climates with organizational goals. Employee engagement, a predictor of productivity and retention, flourishes under leaders who exhibit EI competencies.
Yet, the field is not without its limitations. Measurement inconsistencies, theoretical ambiguities, and lack of cultural contextualization continue to challenge the field's credibility. Moreover, the increasing integration of digital and remote work environments calls for a reimagining of how EI is taught, measured, and practiced in technologically mediated leadership.
Future research must focus on:
• Developing context-specific EI training programs for leaders.
• Designing cross-culturally valid assessment instruments.
• Conducting longitudinal and experimental studies to better establish causal pathways.
• Exploring the neuroscience of emotionally intelligent decision-making.
As organizations become more human-centered in design and purpose, emotional intelligence is poised to remain a cornerstone of ethical, adaptive, and impactful leadership.

Through this unit, many skills are likely to be developed which can be incorporated into resumes and professional portfolios such as:
* Demonstrated ability to use professional knowledge to address applied psychological problems.
* Confidence in written and verbal communication of ideas using collaborative, online platforms.
* Capacity to learn new technologies for addressing novel problems.
If you don't feel confident declaring such skills by the end of the unit then they could be considered targets for further skill development (e.g., through internship).
Consider including your submissions for the unit's [[Motivation and emotion/Assessment/Major project|major project]] assessment items (i.e., the book chapter and multimedia) as work examples (artefacts) in your e-portfolio.<noinclude>

[[File:(at).svg|thumb|upright|The [[w:at sign|at sign]], is a part of each [[w:email|email]] address]]
{{100%done}}
Use this checklist to avoid common [[w:email|email]] errors,<ref>[https://www.lifehack.org/articles/productivity/75-common-email-mistakes-youre-probably-making-work.html 75 Common Email Mistakes You’re Probably Making at Work], Lifehack, Bryan Collins.</ref><sup>,</sup><ref>[https://www.cbsnews.com/news/5-career-destroying-email-blunders/ 5 career-destroying email blunders], CBS News, Dave Johnson, November 3, 2011. </ref> and improve your email communications.
*'''Mode'''—Is email the best communication mode to choose for this message? Would a text message, phone call, video chat, personal visit, card, letter, silence, or handwritten note be more effective?
*'''Recipients'''—Consider carefully who should receive this message. Use these fields and commands carefully:
**To: Carefully identify the email of the person this message is directed to. This is the person who is requested to act on this message.
**CC: If others would benefit from receiving this message, include them here. CC is for people who need to be kept in the know.
**BCC: “Blind Copy” If there is good reason to hide the identity of other recipients, include them here rather than in CC.
**Reply: Use “Reply” to reply only to the originator of this email message.
**Reply all: Use this option carefully and sparingly to avoid sharing your message unnecessarily or inadvertently with all the recipients of the original message.
*'''Nonrecipients'''—Don’t send email to people who will be annoyed by the message. Don’t disclose private information carelessly. Avoid including copies of peer level communications to the boss. Include the boss if you are praising other recipients. Omit the boss if you are critical of recipients or working to resolve conflict.
*'''Subject'''—Choose the language of the subject line carefully. Provide a clear and accurate synopsis. Use the subject line to provide context, clarify intent, or suggest what may be expected of the recipient.
*[[w:Copy_editing|'''Copy Editing''']]—Take care to avoid or correct spelling, word use, grammar, and punctuation errors.
**Spelling—Check the spelling. Use a spell checker.
**Word use—Double check the meaning of any words you are unsure of. Look them up to ensure they mean what you want to communicate. Be particularly careful to check words that have been autocorrected.
**Punctuation—Check the grammar and punctuation. Use a grammar checker.
*'''Call to action'''—What, if any, engagement are you expecting of the recipient? Is this message being sent for entertainment, sharing information, asking a question, assigning a task, suggesting some action, or are you trolling, annoying, gossiping, gloating, harassing, bullying, or bloviating? In business emails it can be helpful to include a one line summary and call to action near the top of the message. Other emails may include some suggested action later in the message. Does the recipient have all the information they need to take the requested action?
*'''Message'''—Communicate clearly, carefully, completely, and purposefully.
**Purpose—Why are you sending this message? Are you sharing information, asking a question, posing a problem, proposing a solution, or simply spreading rumors and gossip? What do you want to have happen as a result of this message? What else might happen? Will this message have a positive impact? Do not send email unless you can improve on silence.
**Style—Separate personal and professional messages and styles. Don’t use personal email language or styles in professional messages, and vice versa.
**Clarity—Good writing is clear thinking made visible.<ref>[https://www.laserfocusworld.com/test-measurement/research/article/16556713/good-writing-is-clear-thinking-made-visible Good writing is clear thinking made visible], LaserFocusedWorld, Jeffrey Bairstow, May 1, 2001. </ref> Is this message based on clear thinking? Is the thought clear? Is the language clear? How can the message be made more valuable? Can you avoid sending this email by answering your own question, or doing your own research or investigation?
***Check the text for inconsistencies and logical fallacies. Consider using a Large Language Model, such as ChatGPT to check the text using the following prompt: “Identify inconsistencies and logical fallacies in the following text. Provide sound counterarguments:”
**Whose problem is this?—If this is your problem to solve, or you can take action to solve the problem, don’t pass it on.<ref>[https://hbr.org/1999/11/management-time-whos-got-the-monkey Management Time: Who’s Got the Monkey?], Harvard Business Review, by William Oncken, Jr. and Donald L. Wass. </ref> Respect the recipient’s time, attention, and privacy.
**Cool Heads—Don’t click send while you are angry, distracted, impatient, tired, under the influence, or in some altered state of consciousness. Wait overnight to reconsider and re-read sensitive, provocative, upsetting, or especially important email messages. If this email appeared in a public forum, or the front page of the newspaper, would that be OK?
**Improved text—Consider using a tool such as ChatGPT to suggest improvements to the text.
*'''Privacy'''—Ensure the privacy of yourself and others, and carefully protect confidential, sensitive, or other protected information. Email privacy breaches have ruined careers.<ref>[https://eccitsolutions.com/simple-email-mistakes-that-can-cause-serious-data-security-breaches/ Simple Email Mistakes That Can Cause Serious Data Security Breaches], ECC IT Solutions.</ref>
*'''Security'''—Assume your email messages are not secure. Do not sent passwords, account numbers, or other sensitive information over email. Learn to recognize spam, phishing, social engineering, and other confidence tricks. Don’t engage with these traps, report them.<ref>[https://www.usa.gov/stop-scams-frauds Report Scams and Frauds], USAGov.</ref>
*'''Good Faith'''—Take care to communicate in good faith. Be impeccable with your word. Advance no falsehoods. Consider if this communication is true, helpful, and kind. Is the email respectful to recipients and others? If not, then don’t send it.
*'''Attachments'''—If you mention an attachment in the message, be sure to include that attachment. Because attachments are often bulky, don’t include them unnecessarily. Use a link to a shared document or on-line resource rather than attaching a copy when practical.
*'''Netiquette'''—Use good manners and exercise civility. Begin with a respectful greeting. End by thanking the recipients. Use respectful language throughout.
Use this checklist to avoid common email errors and improve your email communications.

Engagement by attending lectures and tutorials is strongly recommended but not compulsory.
Non-engagement is likely to make successful completion of the assessment more difficult because:
*Lectures discuss content which is assessed in the quizzes.
*Tutorials develop skills directly related to the [[Motivation and emotion/Assessment/Major project|major project]] (topic development and book chapter) assessment exercises.
If you are unable to attend your scheduled tutorial, attend a tutorial at a different time or access the online recording.
This [[Motivation and emotion/Assessment#Table|table]] estimates the time required to complete the major activities in this unit. Plan to allocate approximately 10 hours per week over 15 weeks.<noinclude>

On the residue class group for a normal subgroup in a group, there are quite often additional structures available, if the group and the normal subgroup fulfill certain properties. In the last lecture, we have looked at residue class spaces for a linear subspace. Here, we discuss briefly residue class rings for an ideal in a commutative ring. We recall the definition of a ring homomorphism.

|abstract = This research aims to provide a detailed and comparative analysis of Histrionic Personality (HP) and Narcissistic Personality (NP) traits, utilizing the Deenz Histrionic Personality Scale (DHPS) and the Deenz Narcissistic Personality Scale (DNPS) developed by Deen (2024). Both HP and NP are personality types characterized by an overwhelming desire for attention and admiration, yet they manifest in distinct ways. Individuals with HP often display excessive emotional expressiveness and seek attention through dramatic and sometimes manipulative behaviors, whereas those with NP tend to present an inflated self-image and seek admiration through a sense of superiority. While these two personality types share overlapping features, such as attention-seeking behaviors, the motivations driving these behaviors differ significantly. The study involved 64 participants who completed the computerized versions of the DHPS and DNPS, measuring various facets that define these two personality types. The data analysis focused on comparing the mean scores and standard deviations for each facet, revealing key differences and similarities in traits such as grandiosity, fantasy, entitlement, emotional reactivity, impulsivity, and empathy. Findings from this study suggest that, while both HP and NP individuals exhibit self-centered tendencies, HP traits are more emotionally reactive, driven by a need for validation through dramatic displays of emotion, whereas NP traits reflect a rigid belief in one’s inherent superiority and entitlement to special treatment. The results have significant implications for clinical diagnosis and intervention strategies, as they enhance our understanding of these complex personality structures and their manifestation in real-world behavior. By examining these personality traits in-depth, this study contributes to the development of more effective diagnostic tools and therapeutic approaches tailored to individuals exhibiting characteristics of HP and NP.
}}
==1. Introduction==
Histrionic Personality (HP) and Narcissistic Personality (NP) are two distinct yet often overlapping personality types that are characterized by patterns of emotional expression, social interactions, and the way individuals seek attention and admiration from others. These personality types are classified as part of the broader category of personality disorders in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5; American Psychiatric Association, 2013), which serves as a critical framework for understanding psychological functioning and diagnosing mental health conditions. While both HP and NP are frequently associated with excessive attention-seeking behavior, the underlying motivations, behaviors, and emotional processes that define each disorder are distinct.
Histrionic Personality Disorder (HPD) is primarily marked by a pervasive pattern of excessive emotionality and attention-seeking. Individuals with HPD are often seen as dramatic, theatrical, and overly expressive, with their emotional responses tending to be exaggerated and out of proportion to the situation at hand (French & Shrestha, 2024). These individuals crave attention and validation, often using their emotional expressions as a means of drawing others’ focus. HPD is typically associated with individuals who demonstrate impulsive behaviors, are sensitive to criticism, and struggle to maintain stable relationships. The intense desire for attention often drives them to seek out situations or relationships where they can be the center of attention, and when they are not the focal point, they may become anxious or distressed (Mitra & Fluyau, 2023).
On the other hand, Narcissistic Personality Disorder (NPD) is defined by an inflated sense of self-importance, a need for admiration, and a lack of empathy for others. Narcissistic individuals believe they are unique or special and expect recognition and special treatment based on these beliefs. NPD is often characterized by a pervasive sense of entitlement, a tendency to exploit others for personal gain, and difficulty in recognizing the feelings and needs of others (American Psychiatric Association, 2013). While individuals with NP share the desire for attention with those who exhibit HP traits, their underlying motivations are often more tied to their self-image and an unshakable belief in their own superiority. Narcissistic individuals typically seek admiration and validation, but this is driven by their need to preserve their idealized self-image rather than by a genuine desire for emotional connection or empathy with others (Mitra & Fluyau, 2023).
While both personality disorders exhibit traits that center around attention-seeking behavior, the ways in which these traits manifest and the social, emotional, and cognitive processes that drive them differ significantly. Research into the similarities and differences between these two personality types is essential to further understanding their underlying causes, their impact on interpersonal relationships, and how they can be addressed in clinical practice. Both HPD and NPD can lead to interpersonal difficulties, emotional distress, and challenges in professional and personal contexts.
==2. Methodology==
This study employs the Deenz Histrionic Personality Scale and Deenz Narcissistic Personality Scale (Deen, 2024) to assess traits associated with both personality types. A total of 64 participants, all adults, completed the computerized version of the scales. Each scale contains specific facets designed to evaluate key behaviors and emotional tendencies that characterize Histrionic and Narcissistic personalities.
The participants' responses were then analyzed to determine significant patterns, including the mean and standard deviation for each trait within both personality constructs. The analysis provided insight into how these two personality types overlap and diverge in terms of emotional responses, behavioral patterns, and interpersonal dynamics.
==3. Findings==
The data analysis revealed distinct differences between the two personality types, with several patterns emerging from the responses. The participants exhibited clear behavioral and emotional tendencies linked to their respective personality types, which are discussed below.
===3.1 Histrionic Personality Facets===
Attention-Seeking: Individuals with Histrionic Personality are highly extroverted and driven by a desire to be the center of attention. Their behaviors are often noticeable, as they tend to engage in over-the-top actions to gain the admiration of others. Whether through excessive talking, exaggerated body language, or seeking sympathy, attention-seeking behaviors dominate this personality type. People with this trait are often perceived as overly dramatic or manipulative in their pursuit of the spotlight (Mitra & Fluyau, 2023).
Excessive Emotionality: Histrionic individuals tend to express their emotions in a dramatic and exaggerated way, particularly when seeking attention or sympathy. They may display theatrical reactions to situations, making their emotional responses appear disproportionate. This trait contributes to their need to evoke strong emotional responses from others (French & Shrestha, 2024).
Attention-Seeking:
Individuals with Histrionic Personality are highly extroverted and driven by a desire to be the center of attention. Their behaviors are often noticeable, as they tend to engage in over-the-top actions to gain the admiration of others. Whether through excessive talking, exaggerated body language, or seeking sympathy, attention-seeking behaviors dominate this personality type. People with this trait are often perceived as overly dramatic or manipulative in their pursuit of the spotlight (Mitra & Fluyau, 2023).
Excessive Emotionality:
Histrionic individuals tend to express their emotions in a dramatic and exaggerated way, particularly when seeking attention or sympathy. They may display theatrical reactions to situations, making their emotional responses appear disproportionate. This trait contributes to their need to evoke strong emotional responses from others (French & Shrestha, 2024).
Hypersensitivity:
This facet describes a heightened sensitivity to not being the center of attention. People with Histrionic Personality often feel uneasy or rejected when they are overlooked or criticized. This hypersensitivity can lead to emotional distress or outbursts, further driving their need for validation.
Impulsivity:
Impulsive behavior is another significant trait of Histrionic Personality. These individuals act on sudden urges, often without considering long-term consequences. This can lead to reckless or risky decisions in both their personal and professional lives.
Seductive Behavior:
Engaging in flirtatious or provocative actions is a common method for individuals with Histrionic Personality to capture attention. Whether intentionally or unconsciously, these behaviors can lead to misunderstandings or discomfort in social settings.
===3.2 Narcissistic Personality Facets===
Grandiosity:
A key feature of Narcissistic Personality is grandiosity, which involves an exaggerated sense of one’s own importance. Individuals with this trait often believe they are superior to others and expect special treatment. They view themselves as exceptional and deserving of admiration (American Psychiatric Association, 2013).
Fantasy:
Narcissistic individuals tend to engage in grandiose fantasies about success, power, and attractiveness. These fantasies act as a defense mechanism to protect against feelings of inadequacy and to boost their self-esteem.
Specialness:
Narcissistic individuals believe they are unique and often expect to be recognized as such. They want to be seen as special and deserving of admiration, which they may actively seek from others.
Entitlement:
A significant trait of Narcissistic Personality is the belief that one deserves special privileges, regardless of whether they’ve earned them. This sense of entitlement can lead to frustration and disappointment when their expectations are not met.
Exploitation:
People with Narcissistic Personality often take advantage of others for personal gain. They may manipulate or exploit others without regard for their well-being, seeing them as tools to maintain or enhance their own status.
Lack of Empathy:
A hallmark of Narcissistic Personality is the inability to understand or care about others’ emotions or needs. Individuals with this trait are focused solely on their own desires and often show little concern for how their actions affect others.
Envy:
Narcissistic individuals may feel envious of others' success and may attempt to undermine or belittle them in order to maintain their own sense of superiority.
Arrogance:
Arrogance is another defining trait of Narcissistic Personality. Individuals with this trait often display a dismissive attitude toward others, believing that they are superior and entitled to more than others.
==4. Discussion==
The findings of this study indicate that while both Histrionic and Narcissistic Personality types exhibit attention-seeking behaviors, the underlying motivations and emotional responses differ. Histrionic individuals tend to express their need for attention through dramatic emotional reactions, whereas Narcissistic individuals seek admiration by promoting their superiority and demanding special treatment. Narcissistic traits are more rigid, self-centered, and associated with a lack of empathy, while Histrionic traits are more reactive, driven by emotional expression, and sometimes impulsive in nature.
These differences suggest that Histrionic individuals are more emotionally driven and often seek emotional validation, whereas Narcissistic individuals are motivated by a desire for status and control over others. Understanding these differences is crucial in diagnosing and treating these personality types, especially in clinical settings.
==5. Conclusion==
Abstract
The significance of Emotional Intelligence (EI) in contemporary organizational environments has become increasingly apparent, particularly concerning its influence on leadership effectiveness and employee engagement. As organizations confront complex demands in an era defined by rapid technological change, globalization, and diverse workforce dynamics, emotionally intelligent leadership is now recognized as an indispensable driver of success. This critical review investigates how EI contributes to leadership capabilities, examining its role in shaping interpersonal relationships, decision-making, conflict management, and motivational strategies. Simultaneously, it explores how emotionally intelligent leaders enhance employee engagement by creating psychologically safe, supportive, and empathetic work environments. Drawing on a wide range of theoretical frameworks and empirical findings from the last three decades, the review highlights both the transformative potential and the limitations of EI in leadership practice. Methodological issues in measurement and cross-cultural applicability are also critically evaluated. The review concludes by identifying key research gaps and offering recommendations for future inquiry, including the need for longitudinal studies, culturally sensitive EI instruments, and more nuanced training interventions.

this also holds for the characteristic polynomial of the matrix we have started with. Hence, {{mat|term= M |pm=}} has an eigenvector to the eigenvalue {{mat|term= 1 |pm=.}}
|We now assume also that all entries of the {{mat|term= k |pm=-}}th row are positive, and let
{{
Relationchain
| v
|\in| V
||
||
||
|pm=
}}
denote a vector with
{{
Extra/Bracket
|text=at least|
|Ipm=|Epm=

a positive and a negative entry. Then
{{

| {{op:Sum norm|Mv}}
|| \sum_{ i {{=}} 1}^n {{op:Modulus| (Mv)_i}}
|| \sum_{ i {{=}} 1}^n {{op:Modulus| \sum_{j {{=}} 1}^n a_{ij} v_j }}
|| \sum_{ i \neq k} {{op:Modulus| \sum_{j {{=}} 1}^n a_{ij} v_j }} + {{op:Modulus| \sum_{j {{=}} 1}^n a_{kj} v_j }}

|| \sum_{ j {{=}} 1}^n {{op:Modulus|v_j|}}
|| {{op:Sum norm|v}}

holds.
|As in the proof of (2), let all entries of the {{mat|term= k |pm=-}}th row be positive. For any eigenvector {{mat|term= v |pm=}} to the eigenvalue {{mat|term= 1 |pm=,}} according to (2), either all entries are non-negative, or non-positive. Hence, for such a vector, because of
{{
Relationchain
| Mv
|| v
||
||
||
|pm=,
}}
its {{mat|term= k |pm=-}}th entry is not {{mat|term= 0 |pm=.}} Let {{mat|term= v,w|pm=}} be such eigenvectors. Then {{mathl|term= {{op:Fraction|w_k|v_k}} v-w |pm=}} belongs to the fixed space. However, the {{mat|term= k |pm=-}}th component of this vector equals {{mat|term= 0 |pm=;}} therefore, it is the zero vector. This means that
{{
Mathcor|term1=
v
|and|term2=
w
|pm=
}}
are
{{
Definitionlink
|linearly dependent|
|Context=|
|pm=.
}}
Therefore, this eigenspace is one-dimensional. Because of (2), there exists an eigenvector to the eigenvalue {{mat|term= 1 |pm=}} with non-negative entries. By normalizing, we get a stationary distribution.

== 4 LLM interfaces ==
There are a variety of tools that are available to individuals or organiations that want to provide a platform to use LLMs in a highly controlled, secure and managed environment.
The first LLM interface...
Hugging Face...
Brief history of the movement to make open source LLM interfaces.
With the main goal of the AIX Workbench, there were a few points of considerations that needed to be met. We needed the LLM Interface to be able to be modified so it satisfies the following characteristics:
* Secure
* Responsible
* Replicable
* Shareable/Collaborative
* Deployable
The most commonly used "AI" by far are the cloud-based ones. Although, they have beginner friendly ease-of-access, the issue with most cloud-based LLM is that they are run and operated by the provider's machine. In addition, the limited customizability and data privacy concerns makes them a questionable use for the AIX Workbench. The limited customizability doesn't allow the user to modify parameters. The major data privacy concerns is that the provider could use the user's chats & documents to train its models, which means sensitive information could be exposed.<ref>{{Cite web|url=https://www.datacamp.com/blog/the-pros-and-cons-of-using-llm-in-the-cloud-versus-running-llm-locally|title=The Pros and Cons of Using Large Language Models (LLMs) in the Cloud vs. Running LLMs Locally: Which Is Right for You?|last=Ali Awan|first=Abid|date=May 23, 2023|website=datacamp.com}}</ref>

= '''Chapter 7: Cosmological Parameters and Universal Constants''' =
=== '''7.1 – Purpose – Overview Cosmological Parameters and Universal Constants''' ===
This subsection introduces the key cosmological parameters and universal constants that underpin modern models of the universe. These values are foundational for describing the large-scale structure, expansion history, and composition of the cosmos. By defining and constraining these constants, researchers are able to test, compare, and refine competing cosmological theories.
The most widely used parameters include:
'''Hubble Constant (H₀)''' – The current rate of cosmic expansion, typically expressed in km/s/Mpc. It plays a central role in determining the age and scale of the universe.
'''Matter Density Parameter (Ωₘ)''' – The fraction of the critical density contributed by all forms of matter (baryonic and dark matter).
'''Dark Energy Density Parameter (Ω_Λ)''' – The fraction of the critical density attributed to dark energy, often associated with the cosmological constant (Λ).
'''Spectral Index (nₛ)''' – Characterizes the scale dependence of primordial density fluctuations.
'''Amplitude of Scalar Fluctuations (Aₛ)''' – Sets the overall level of fluctuations in the early universe, which seeded the formation of galaxies and clusters.
'''Optical Depth (τ)''' – Relates to the reionization history of the universe, affecting how the cosmic microwave background (CMB) photons have been scattered.
'''σ₈''' – A measure of the clustering strength of matter on scales of 8 h⁻¹ Mpc, used in large-scale structure studies.
These parameters are complemented by a set of universal physical constants that appear across all physical theories:
'''Gravitational Constant (G)'''
'''Speed of Light (c)'''
'''Planck’s Constant (h)'''
'''Boltzmann Constant (k_B)'''
'''Cosmological Constant (Λ)''' – interpreted as vacuum energy or dark energy density
'''Fine-Structure Constant (α)'''
Together, these parameters serve as the empirical backbone for cosmological models, allowing them to be calibrated against observational data. Most mainstream models—such as the ΛCDM model—use a minimal set of six to seven parameters, yet tensions persist between different measurement techniques. For example, the value of H₀ inferred from the cosmic microwave background (CMB) differs significantly from values measured using Type Ia supernovae, leading to the well-known '''Hubble tension'''. Similarly, discrepancies in measurements of σ₈ suggest the possibility of unknown physical processes or the need for alternative frameworks.
This chapter evaluates how different cosmological theories define, derive, or reinterpret these parameters. It also considers whether a theory proposes a new universal constant, modifies existing ones, or offers an explanation for observed tensions. The role of these constants in the internal logic and predictive success of a theory is an essential component of the comparative evaluation.
=== '''7.2 – Scope – Mainstream and Non-mainstream Theories''' ===
This subsection outlines the scope of Chapter 7 in terms of the cosmological theories being considered, with specific attention to how each theory engages with cosmological parameters and universal constants. Both mainstream and non-mainstream theories are included in the evaluation to ensure a broad, inclusive, and critically informed comparison.
==== '''Mainstream Cosmological Frameworks''' ====
Mainstream cosmological models are those widely accepted within the current scientific consensus and supported by large-scale observational programs such as the Planck satellite, the Sloan Digital Sky Survey (SDSS), and the Dark Energy Survey (DES). The primary framework is the:
'''ΛCDM Model (Lambda Cold Dark Matter)'''
This model is based on general relativity and assumes a universe dominated by cold dark matter (CDM) and a cosmological constant (Λ) representing dark energy. It uses a standard set of six parameters to fit observational data:
– H₀ (Hubble constant)
– Ωₘ (matter density)
– Ω_Λ (dark energy density)
– nₛ (spectral index)
– Aₛ (amplitude of fluctuations)
– τ (optical depth)
ΛCDM has achieved notable empirical success, including accurate fits to the cosmic microwave background (CMB) power spectrum and the large-scale distribution of galaxies. However, it faces unresolved tensions such as the disparity in H₀ values derived from early- and late-universe measurements, and differences in predicted versus observed values of σ₈ (matter clustering amplitude).
Other general relativity–based extensions or modifications, such as quintessence models (dynamic dark energy), modified gravity (e.g., f(R) theories), or models invoking additional neutrino species, are sometimes treated as extensions of ΛCDM rather than fundamentally separate theories.
==== '''Non-Mainstream and Emerging Theories''' ====
This chapter also includes theories that are not currently part of mainstream consensus but that offer new approaches to cosmological constants or parameter derivation. These may include:
'''Alternative Gravity Theories''' – including MOND (Modified Newtonian Dynamics), TeVeS, conformal gravity, and entropic gravity. These models often aim to explain galactic rotation curves or cosmological structure without invoking dark matter.
'''Emergent and Flow-based Models''' – including theories where cosmic structure arises from energy influxes or universal flows (e.g., Cosmic Influx Theory, Spiral Cosmology). These models may propose new constants (such as influx-based scaling parameters) or reinterpret standard ones.
'''Continuous Creation or Steady-State Frameworks''' – These posit a continuous generation of matter or energy, potentially affecting the interpretation of Hubble expansion, cosmic microwave background, and the age of the universe.
'''Topological or Geometric Reinterpretations''' – Some proposals modify the dimensionality or topology of space-time itself, redefining how constants such as G or c emerge from underlying structures.
==== '''Comparative Perspective''' ====
By evaluating both mainstream and non-mainstream approaches on equal terms, this chapter aims to provide a comparative framework grounded in empirical adequacy, predictive capacity, and internal coherence. The inclusion of non-standard models is not intended to imply equivalence of scientific status, but rather to highlight the diversity of ideas that reinterpret or challenge conventional uses of cosmological parameters.
The theories evaluated here must define how they handle:
The derivation or reinterpretation of cosmological parameters
The role and meaning of universal constants in their framework
Their position relative to known tensions (e.g., Hubble tension, σ₈ tension)
This scope ensures that all models are critically evaluated using the same criteria, while allowing room for genuinely novel approaches to cosmology.
== '''7.3 How to Contribute a Theory ''' ==
Researchers and contributors are welcome to propose additional theories that relate biological evolution and fossil records to planetary or cosmological models. Submissions may include observational insights, mathematical models, conceptual frameworks, or hybrid approaches.
You can contribute in either of the following ways:
* Post directly on the Talk page of this chapter
* Or email your proposal to: aitheroymapping@gmail.com
All submitted theories will be added to the mapping and evaluated using the shared criteria defined in Chapter 1.3: Evaluation Criteria. We encourage both mainstream and non-mainstream contributors to join this open effort to compare and improve our understanding of Biological and Paleontological Clues in relation to cosmological theories.
=== '''7.4 – Theory Mapping Table''' ===
This table presents a structured comparison of diverse cosmological theories based on how they define or reinterpret key cosmological parameters and universal constants. The table includes both mainstream and non-mainstream paradigms, encouraging open comparative analysis grounded in scientific rigor.

=== '''7.5 Evaluation Criteria and Comparative Overview''' ===
The cosmological theories presented in this chapter are evaluated using the shared set of criteria defined in [[AI-Assisted_Evaluation_of_Cosmological_Theories/Chapter_1:_Introduction_and_Evaluation_Criteria#1.3:_List_of_Evaluation_Criteria|Chapter 1.3: List of Evaluation Criteria]]. These criteria are here specifically applied to how each theory handles cosmological parameters and universal constants.
'''Empirical Adequacy''' – alignment with observed values of key parameters (H₀, Ωₘ, Λ, σ₈, etc.) and data from CMB, supernovae, BAO, and large-scale structure
'''Internal Consistency''' – logical and mathematical coherence in the derivation or treatment of constants
'''Explanatory Power''' – ability to explain why constants have their observed values, not just fit them
'''Predictive Power''' – capacity to forecast future or unmeasured parameter values or resolve current tensions (e.g., Hubble tension)
'''Simplicity and Elegance''' – conceptual parsimony and avoidance of unnecessary parameters or fine-tuning
'''Compatibility with Other Theories''' – ability to integrate with broader physical theories and cosmological observations
'''Falsifiability and Openness to Testing''' – presence of testable predictions or measurable consequences
The paragraphs below summarize how each theory relates to these criteria. A more detailed AI-supported analysis follows in Section 7.6.
'''ΛCDM (Standard Model)''' is strongly supported by observational data and has high empirical adequacy. Its internal consistency and predictive power are well-established, especially in modeling the CMB and galaxy distributions. However, it treats many constants as fitted parameters without deeper explanation. The model faces known tensions in H₀ and σ₈, which challenge its completeness. It is conceptually simple and highly compatible with general relativity and particle physics, and its parameters are open to observational testing.
'''Modified Gravity (f(R))''' introduces geometric generalizations of Einstein's equations, potentially explaining dark energy and dark matter effects through curvature. While it can match observational data under certain models, its parameter space is broad, and empirical adequacy depends heavily on specific formulations. It offers improved explanatory potential over ΛCDM in some cases, but at the cost of increased mathematical complexity. Some forms are testable via gravitational lensing, structure formation, and precision cosmology.
'''MOND / TeVeS''' modifies Newtonian dynamics to eliminate the need for dark matter at galactic scales. It reproduces galactic rotation curves successfully but struggles at cosmological scales. Its internal logic is consistent within its regime of applicability, and it introduces the acceleration scale a₀ as a new constant. Predictive power is good for galaxies but limited for early-universe physics. MOND-type theories are testable but not easily reconciled with CMB data or structure formation.
'''Emergent Gravity (Verlinde)''' reinterprets gravity as an emergent entropic force arising from information-theoretic principles. It provides an elegant and conceptually innovative explanation of dark energy and inertia, but its empirical adequacy is still under investigation. It offers strong explanatory power in principle but lacks complete predictive frameworks for all cosmological parameters. The theory is testable in principle through deviations from Newtonian gravity in specific regimes, though experimental confirmation remains elusive.
'''Cosmic Influx Theory (CIT)''' derives the Hubble constant from influx-based relationships involving VRMS and the relativistic factor (γ−1), matching Planck-derived values. While some standard parameters (e.g., Ω values) are not explicitly defined, CIT offers strong internal consistency and explanatory power for G and H₀ via fundamental influx mechanisms. Its simplicity and dimensional coherence are strengths, though full cosmological compatibility and falsifiability require further development. It aligns with observed tensions and provides a novel conceptual bridge between gravity, expansion, and mass generation.
'''Spiral Cosmology''' explains cosmic structure and evolution through geometrically spiraling flows of energy and matter. It reinterprets constants as emergent from dynamic motion patterns rather than fixed inputs. Its empirical alignment is currently qualitative, but it provides strong explanatory power for structure formation and symmetry. Its conceptual elegance appeals to analogies in electromagnetic and wave theory. Predictive models and testable consequences remain a work in progress, but the theory is logically consistent within its internal framework.
'''Topological Field Framework (Hall)''' proposes that fundamental constants emerge from field topology in higher-dimensional configurations. It offers potential explanations for G, c, and Λ as emergent from geometry rather than fixed inputs. While still under development, it has strong internal logic and high explanatory ambition. Its empirical adequacy depends on deriving measurable predictions. Its compatibility with both general relativity and quantum geometry gives it interdisciplinary appeal, though full falsifiability is pending.
'''Conformal Gravity (Mannheim–Kazanas)''' eliminates the need for dark matter by modifying gravitational equations with conformal symmetry. It fits galactic rotation curves and some lensing observations without introducing new particles. Its predictive power is good at galactic scales, and it offers a deep geometric motivation for its equations. However, it faces challenges matching CMB and early-universe data. The theory is testable and internally consistent, but its cosmological compatibility is debated.
'''Quasi-Steady State Cosmology (QSSC)''' offers a cyclic, matter-generating model that modifies standard expansion assumptions. It reproduces redshift data through a non-Big Bang framework and introduces a creation field (C) as a new constant. Its empirical adequacy is mixed, and its compatibility with observed element abundances and CMB is questioned. However, its explanatory ambition and falsifiability through periodic structure and matter creation make it a valuable alternative perspective.
'''Dynamic Universe (Tuomo Suntola)''' proposes a zero-energy balance model in which cosmic parameters evolve from a unified dynamic geometry. It predicts H₀ and other constants from time-dependent curvature rather than fixed values. The theory is internally consistent, compact, and provides strong explanatory value for the origin of physical laws. Its compatibility with relativity is nonstandard but mathematically consistent. Observational tests are possible through detailed cosmological reconstructions and time-scaling relationships.
=== '''7.6 – AI Evaluation Based on Shared Criteria''' ===
This subsection presents an AI-assisted comparative evaluation of cosmological theories, based on the shared criteria defined in [[AI-Assisted_Evaluation_of_Cosmological_Theories/Chapter_1:_Introduction_and_Evaluation_Criteria#1.3:_List_of_Evaluation_Criteria|Chapter 1.3: List of Evaluation Criteria]]. The goal is to clarify how each theory treats the fundamental cosmological parameters and universal constants discussed in this chapter. The evaluation highlights internal coherence, empirical alignment, explanatory ambition, and potential testability.
No star ratings are assigned here. Instead, each theory is qualitatively assessed across the criteria through short descriptive paragraphs.
'''ΛCDM (Standard Model)''' offers strong empirical alignment with CMB, supernova, and large-scale structure data. Its internal structure is based on general relativity and well-developed mathematical models, making it logically robust. However, it provides limited explanation for the specific values of constants such as H₀ or Λ, which are treated as empirical inputs. Despite this, it demonstrates predictive success across multiple observations. The model is conceptually economical, relying on a minimal parameter set, and is deeply integrated into the broader framework of modern physics. Known tensions (e.g., H₀ discrepancy) invite refinement or reinterpretation but do not undermine its overall compatibility with data. It remains broadly testable through increasingly precise cosmological measurements.
'''Modified Gravity (f(R))''' theories attempt to explain dark energy and acceleration through extensions of the Einstein-Hilbert action. They offer a reinterpretation of cosmic parameters in terms of curvature dynamics rather than exotic energy components. These models vary widely in structure and observational fit, depending on the chosen function f(R), but many reproduce key cosmological features. Their mathematical framework is internally consistent, and they contribute meaningfully to the debate on the nature of gravity. While their explanatory power is promising, some formulations require additional parameters or fine-tuning. Compatibility with structure formation data and gravitational lensing tests remains an important area for empirical evaluation.
'''MOND / TeVeS''' seeks to account for galactic rotation curves without invoking dark matter, introducing a critical acceleration scale as a new constant. It performs very well at galactic scales, offering a direct fit to rotation data. However, it faces challenges when applied to cosmological phenomena such as the cosmic microwave background and large-scale structure. The theory’s internal dynamics are logically constructed and mathematically consistent within their range of application. Its predictive capacity is constrained to specific regimes, and it introduces conceptual simplicity with minimal new constants. Empirical tensions with high-redshift data suggest the need for further development or hybrid models.
'''Emergent Gravity (Verlinde)''' offers an innovative theoretical framework in which gravity and inertia emerge from entropic and information-theoretic principles. This model reframes fundamental constants as emergent properties of underlying entropy distributions. While its internal structure is elegant and conceptually coherent, empirical validation remains limited. It has provided tentative fits to certain lensing effects, but full cosmological modeling is still in development. The theory’s explanatory reach is broad, particularly in redefining Λ and inertia, though specific quantitative predictions are still rare. It is testable in principle, and future observational probes could refine or challenge its foundational assumptions.
'''Cosmic Influx Theory (CIT)''' proposes that the gravitational constant and Hubble parameter derive from a continuous influx of energy into matter. It uses the relativistic factor (γ−1) and a universal root mean square velocity (VRMS) to derive G and H₀, aligning with Planck observations without parameter fitting. The theory is internally consistent and offers strong explanatory coherence for the emergence of constants. Although it does not define all standard cosmological parameters, its introduction of scaling constants (κ and κ_CIT) provides a novel interpretation of structure and mass-energy evolution. The theory is open to falsification through predictions on orbital dynamics and preferred planetary distances, and invites new observational research.
'''Spiral Cosmology''' describes the evolution of the universe through organized spiraling flows of energy and matter. It offers a dynamic interpretation of cosmic structure and attempts to derive constants from the geometry of spiral motion. Its explanatory framework is creative and unified, though primarily qualitative at this stage. Observational alignment is still under development, and quantitative predictions remain limited. The model maintains internal coherence and offers potential compatibility with both geometric and wave-based models of the universe. It presents a unique lens on cosmic evolution and may be tested through pattern recognition in galactic distributions and background structure.
'''Topological Field Framework (Hall)''' attempts to explain the emergence of physical constants and structure from the topology of underlying fields. It replaces fixed constants with dynamic relationships determined by higher-dimensional field configurations. This theory is conceptually ambitious and mathematically coherent within its proposed framework. While it currently lacks detailed empirical predictions, it offers a strong explanatory model for the origin of constants such as G and c. The framework’s future success depends on its ability to generate testable consequences and interface with observational cosmology.
'''Conformal Gravity (Mannheim–Kazanas)''' modifies general relativity using conformal symmetry and has had success fitting galactic rotation curves without dark matter. It interprets cosmic acceleration and gravitational potentials without requiring Λ or exotic matter components. The theory’s structure is mathematically rigorous and geometrically elegant. While it fits some astrophysical data well, its compatibility with the CMB and early universe remains under scrutiny. It provides a deeper explanation for gravitational behavior, but requires additional work to extend to full cosmological predictions. It is empirically testable and offers a valuable challenge to conventional dark matter models.
'''Quasi-Steady State Cosmology (QSSC)''' revives and modifies the steady-state model by introducing a continuous creation field (C-field) and cyclic cosmological evolution. It offers an alternative interpretation of redshift and cosmic expansion that challenges the Big Bang model. The theory aligns with some observational patterns but struggles to reproduce others, such as the CMB spectrum and light element abundances. Its internal logic is self-consistent within its paradigm and introduces an original approach to matter generation and cosmic cycles. QSSC provides testable ideas, particularly related to periodicity and structural evolution, but remains outside the mainstream due to its divergence from accepted data interpretations.
'''Dynamic Universe (Tuomo Suntola)''' introduces a zero-energy cosmological model in which space, time, and matter evolve from a dynamically balanced 4-sphere geometry. This framework offers a coherent mathematical structure with an explicit derivation of H₀ and other constants from curvature and motion, rather than treating them as empirical inputs. It avoids the need for inflation, dark energy, or dark matter by reinterpreting cosmic expansion. The model’s internal consistency is strong, and its elegance lies in its unified geometric logic. Testable consequences emerge through its time-scaling formulations and reconstruction of historical cosmic dynamics, providing a fertile ground for further research.
=== '''7.7 – Helicopter View – Scientific Reception and Emerging Tensions''' ===
This subsection offers a broader reflection on how the theories presented in Chapter 7 are received within the scientific community, and how ongoing observational tensions and theoretical gaps have shaped the landscape of cosmological research. While the '''ΛCDM model''' remains the dominant paradigm, persistent anomalies and the rise of innovative frameworks have stimulated growing interest in alternatives that offer novel interpretations of cosmological parameters and universal constants.
The '''ΛCDM model''' has achieved widespread acceptance due to its empirical success in matching high-precision data from the Planck satellite, baryon acoustic oscillations, and Type Ia supernovae. Its internal consistency and predictive utility are widely recognized. However, the model also leaves several foundational questions unresolved. Chief among these is the origin and nature of the '''cosmological constant (Λ)''', which contributes over 68% of the energy density of the universe and yet remains theoretically unexplained. Furthermore, the persistent disparity between early-universe (CMB-derived) and late-universe (distance ladder) measurements of the '''Hubble constant (H₀)''' has become known as the '''"Hubble tension"'''. Similar discrepancies related to the amplitude of matter clustering ('''σ₈''') have raised additional concerns about potential missing physics.
These tensions have opened a window for the exploration of '''non-mainstream cosmologies'''. '''Modified gravity models''' such as '''f(R)''' and '''conformal gravity''' offer geometric alternatives that attempt to reproduce cosmic acceleration and structure formation without invoking dark energy or dark matter. While these models often require additional functions or parameters, they are gaining attention for their potential to resolve observational anomalies through new mathematical structures.
Theories such as '''MOND''', '''TeVeS''', and '''emergent gravity''' have had mixed receptions. '''MOND''' has provided compelling fits to galactic rotation curves but lacks a fully developed cosmological extension. '''Emergent gravity''' introduces a radically different ontology—treating gravity and inertia as statistical phenomena—which appeals to theorists seeking deeper unifying principles. Nonetheless, these theories face strong skepticism from mainstream cosmologists due to limited empirical validation and difficulties in reproducing CMB anisotropies and structure growth data.
The inclusion of conceptual models such as '''Spiral Cosmology''', '''Cosmic Influx Theory (CIT)''', and the '''Dynamic Universe''' represents a growing movement within the scientific periphery to explore frameworks that derive cosmological constants from deeper principles—be they geometric, energetic, or topological. These models often operate outside the dominant institutional research programs, yet they reflect a longstanding scientific aspiration: to understand not only how the universe behaves, but why the constants that govern its behavior take the values they do.
Institutional acceptance of these models varies widely. Peer-reviewed publications remain limited for some, while others circulate primarily via academic repositories, conferences, or platforms such as '''Zenodo''', '''ResearchGate''', or '''Wikiversity'''. This reflects a broader tension in the scientific ecosystem: while mainstream paradigms are highly productive and empirically successful, they may not fully accommodate unconventional but potentially insightful hypotheses.
In this context, the '''AI-assisted comparative framework''' applied in this chapter aims to foster transparent, criteria-based evaluation of both accepted and emerging theories. By focusing on '''empirical adequacy''', '''internal logic''', and '''explanatory potential'''—rather than academic consensus alone—this approach supports a more inclusive and methodologically consistent cosmological discourse.
=== '''7.8 – Next Steps''' ===
This final subsection outlines recommended next steps for researchers, contributors, and interested readers following the comparative evaluation of cosmological parameters and universal constants in Chapter 7.
First, contributors are encouraged to refine or expand the theory entries presented here by improving clarity, adding new references, or providing updated observational data. As ongoing missions such as the '''James Webb Space Telescope (JWST)''', '''Euclid''', and the '''Vera Rubin Observatory''' generate increasingly precise cosmological measurements, all models—mainstream and alternative—will face new opportunities for testing and validation. Particular attention should be paid to how each theory addresses current tensions, including the '''Hubble tension''', the '''σ₈ clustering discrepancy''', and the unexplained nature of '''Λ (dark energy)'''.
Second, AI-assisted comparative tools may be developed further to support large-scale cross-analysis of parameter predictions and internal consistencies. This could include algorithmic comparison of theory-derived parameter sets against datasets from Planck, SDSS, DESI, or gravitational wave observatories. Readers or institutions with expertise in computational cosmology are invited to explore these possibilities and report outcomes.
Third, alternative frameworks that derive constants from first principles—whether geometric, entropic, influx-based, or topological—may benefit from collaborative dialogue. Theories such as '''CIT''', '''Spiral Cosmology''', and the '''Dynamic Universe''' propose unorthodox but structured ways to reinterpret physical constants. These models can be further explored, modified, or combined in search of converging predictions.
Finally, this chapter should remain a living document. As the boundaries of cosmology continue to evolve, Wikiversity provides an open-access platform for iterative updates, interdisciplinary integration, and transparent evaluation. Contributors from all scientific backgrounds are welcome to propose revisions, submit new models, or refine the criteria used here. The comparative structure established in Chapter 7 will also serve as a foundation for deeper synthesis in [[AI-Assisted_Evaluation_of_Cosmological_Theories/Chapter_8:_Critical_Evaluation_and_Future_Research_Paths|Chapter 8]], where star ratings, meta-evaluations, and future research priorities will be formally proposed.

=== '''7.1 – Purpose – Overview Cosmological Parameters and Universal Constants''' ===
This subsection introduces the key cosmological parameters and universal constants that underpin modern models of the universe. These values are foundational for describing the large-scale structure, expansion history, and composition of the cosmos. By defining and constraining these constants, researchers are able to test, compare, and refine competing cosmological theories.
The most widely used parameters include:
'''Hubble Constant (H₀)''' – The current rate of cosmic expansion, typically expressed in km/s/Mpc. It plays a central role in determining the age and scale of the universe.
'''Matter Density Parameter (Ωₘ)''' – The fraction of the critical density contributed by all forms of matter (baryonic and dark matter).
'''Dark Energy Density Parameter (Ω_Λ)''' – The fraction of the critical density attributed to dark energy, often associated with the cosmological constant (Λ).
'''Spectral Index (nₛ)''' – Characterizes the scale dependence of primordial density fluctuations.
'''Amplitude of Scalar Fluctuations (Aₛ)''' – Sets the overall level of fluctuations in the early universe, which seeded the formation of galaxies and clusters.
'''Optical Depth (τ)''' – Relates to the reionization history of the universe, affecting how the cosmic microwave background (CMB) photons have been scattered.
'''σ₈''' – A measure of the clustering strength of matter on scales of 8 h⁻¹ Mpc, used in large-scale structure studies.
These parameters are complemented by a set of universal physical constants that appear across all physical theories:
'''Gravitational Constant (G)'''
'''Speed of Light (c)'''
'''Planck’s Constant (h)'''
'''Boltzmann Constant (k_B)'''
'''Cosmological Constant (Λ)''' – interpreted as vacuum energy or dark energy density
'''Fine-Structure Constant (α)'''
Together, these parameters serve as the empirical backbone for cosmological models, allowing them to be calibrated against observational data. Most mainstream models—such as the ΛCDM model—use a minimal set of six to seven parameters, yet tensions persist between different measurement techniques. For example, the value of H₀ inferred from the cosmic microwave background (CMB) differs significantly from values measured using Type Ia supernovae, leading to the well-known '''Hubble tension'''. Similarly, discrepancies in measurements of σ₈ suggest the possibility of unknown physical processes or the need for alternative frameworks.
This chapter evaluates how different cosmological theories define, derive, or reinterpret these parameters. It also considers whether a theory proposes a new universal constant, modifies existing ones, or offers an explanation for observed tensions. The role of these constants in the internal logic and predictive success of a theory is an essential component of the comparative evaluation.
=== '''7.2 – Scope – Mainstream and Non-mainstream Theories''' ===
This subsection outlines the scope of Chapter 7 in terms of the cosmological theories being considered, with specific attention to how each theory engages with cosmological parameters and universal constants. Both mainstream and non-mainstream theories are included in the evaluation to ensure a broad, inclusive, and critically informed comparison.
==== '''Mainstream Cosmological Frameworks''' ====
Mainstream cosmological models are those widely accepted within the current scientific consensus and supported by large-scale observational programs such as the Planck satellite, the Sloan Digital Sky Survey (SDSS), and the Dark Energy Survey (DES). The primary framework is the:
'''ΛCDM Model (Lambda Cold Dark Matter)'''
This model is based on general relativity and assumes a universe dominated by cold dark matter (CDM) and a cosmological constant (Λ) representing dark energy. It uses a standard set of six parameters to fit observational data:
– H₀ (Hubble constant)
– Ωₘ (matter density)
– Ω_Λ (dark energy density)
– nₛ (spectral index)
– Aₛ (amplitude of fluctuations)
– τ (optical depth)
ΛCDM has achieved notable empirical success, including accurate fits to the cosmic microwave background (CMB) power spectrum and the large-scale distribution of galaxies. However, it faces unresolved tensions such as the disparity in H₀ values derived from early- and late-universe measurements, and differences in predicted versus observed values of σ₈ (matter clustering amplitude).
Other general relativity–based extensions or modifications, such as quintessence models (dynamic dark energy), modified gravity (e.g., f(R) theories), or models invoking additional neutrino species, are sometimes treated as extensions of ΛCDM rather than fundamentally separate theories.
==== '''Non-Mainstream and Emerging Theories''' ====
This chapter also includes theories that are not currently part of mainstream consensus but that offer new approaches to cosmological constants or parameter derivation. These may include:
'''Alternative Gravity Theories''' – including MOND (Modified Newtonian Dynamics), TeVeS, conformal gravity, and entropic gravity. These models often aim to explain galactic rotation curves or cosmological structure without invoking dark matter.
'''Emergent and Flow-based Models''' – including theories where cosmic structure arises from energy influxes or universal flows (e.g., Cosmic Influx Theory, Spiral Cosmology). These models may propose new constants (such as influx-based scaling parameters) or reinterpret standard ones.
'''Continuous Creation or Steady-State Frameworks''' – These posit a continuous generation of matter or energy, potentially affecting the interpretation of Hubble expansion, cosmic microwave background, and the age of the universe.
'''Topological or Geometric Reinterpretations''' – Some proposals modify the dimensionality or topology of space-time itself, redefining how constants such as G or c emerge from underlying structures.
==== '''Comparative Perspective''' ====
By evaluating both mainstream and non-mainstream approaches on equal terms, this chapter aims to provide a comparative framework grounded in empirical adequacy, predictive capacity, and internal coherence. The inclusion of non-standard models is not intended to imply equivalence of scientific status, but rather to highlight the diversity of ideas that reinterpret or challenge conventional uses of cosmological parameters.
The theories evaluated here must define how they handle:
The derivation or reinterpretation of cosmological parameters
The role and meaning of universal constants in their framework
Their position relative to known tensions (e.g., Hubble tension, σ₈ tension)
This scope ensures that all models are critically evaluated using the same criteria, while allowing room for genuinely novel approaches to cosmology.

=== '''7.5 Evaluation Criteria and Comparative Overview''' ===
The cosmological theories presented in this chapter are evaluated using the shared set of criteria defined in [[AI-Assisted_Evaluation_of_Cosmological_Theories/Chapter_1:_Introduction_and_Evaluation_Criteria#1.3:_List_of_Evaluation_Criteria|Chapter 1.3: List of Evaluation Criteria]]. These criteria are here specifically applied to how each theory handles cosmological parameters and universal constants.
'''Empirical Adequacy''' – alignment with observed values of key parameters (H₀, Ωₘ, Λ, σ₈, etc.) and data from CMB, supernovae, BAO, and large-scale structure
'''Internal Consistency''' – logical and mathematical coherence in the derivation or treatment of constants
'''Explanatory Power''' – ability to explain why constants have their observed values, not just fit them
'''Predictive Power''' – capacity to forecast future or unmeasured parameter values or resolve current tensions (e.g., Hubble tension)
'''Simplicity and Elegance''' – conceptual parsimony and avoidance of unnecessary parameters or fine-tuning
'''Compatibility with Other Theories''' – ability to integrate with broader physical theories and cosmological observations
'''Falsifiability and Openness to Testing''' – presence of testable predictions or measurable consequences
The paragraphs below summarize how each theory relates to these criteria. A more detailed AI-supported analysis follows in Section 7.6.
'''ΛCDM (Standard Model)''' is strongly supported by observational data and has high empirical adequacy. Its internal consistency and predictive power are well-established, especially in modeling the CMB and galaxy distributions. However, it treats many constants as fitted parameters without deeper explanation. The model faces known tensions in H₀ and σ₈, which challenge its completeness. It is conceptually simple and highly compatible with general relativity and particle physics, and its parameters are open to observational testing.
'''Modified Gravity (f(R))''' introduces geometric generalizations of Einstein's equations, potentially explaining dark energy and dark matter effects through curvature. While it can match observational data under certain models, its parameter space is broad, and empirical adequacy depends heavily on specific formulations. It offers improved explanatory potential over ΛCDM in some cases, but at the cost of increased mathematical complexity. Some forms are testable via gravitational lensing, structure formation, and precision cosmology.
'''MOND / TeVeS''' modifies Newtonian dynamics to eliminate the need for dark matter at galactic scales. It reproduces galactic rotation curves successfully but struggles at cosmological scales. Its internal logic is consistent within its regime of applicability, and it introduces the acceleration scale a₀ as a new constant. Predictive power is good for galaxies but limited for early-universe physics. MOND-type theories are testable but not easily reconciled with CMB data or structure formation.
'''Emergent Gravity (Verlinde)''' reinterprets gravity as an emergent entropic force arising from information-theoretic principles. It provides an elegant and conceptually innovative explanation of dark energy and inertia, but its empirical adequacy is still under investigation. It offers strong explanatory power in principle but lacks complete predictive frameworks for all cosmological parameters. The theory is testable in principle through deviations from Newtonian gravity in specific regimes, though experimental confirmation remains elusive.
'''Cosmic Influx Theory (CIT)''' derives the Hubble constant from influx-based relationships involving VRMS and the relativistic factor (γ−1), matching Planck-derived values. While some standard parameters (e.g., Ω values) are not explicitly defined, CIT offers strong internal consistency and explanatory power for G and H₀ via fundamental influx mechanisms. Its simplicity and dimensional coherence are strengths, though full cosmological compatibility and falsifiability require further development. It aligns with observed tensions and provides a novel conceptual bridge between gravity, expansion, and mass generation.
'''Spiral Cosmology''' explains cosmic structure and evolution through geometrically spiraling flows of energy and matter. It reinterprets constants as emergent from dynamic motion patterns rather than fixed inputs. Its empirical alignment is currently qualitative, but it provides strong explanatory power for structure formation and symmetry. Its conceptual elegance appeals to analogies in electromagnetic and wave theory. Predictive models and testable consequences remain a work in progress, but the theory is logically consistent within its internal framework.
'''Topological Field Framework (Hall)''' proposes that fundamental constants emerge from field topology in higher-dimensional configurations. It offers potential explanations for G, c, and Λ as emergent from geometry rather than fixed inputs. While still under development, it has strong internal logic and high explanatory ambition. Its empirical adequacy depends on deriving measurable predictions. Its compatibility with both general relativity and quantum geometry gives it interdisciplinary appeal, though full falsifiability is pending.
'''Conformal Gravity (Mannheim–Kazanas)''' eliminates the need for dark matter by modifying gravitational equations with conformal symmetry. It fits galactic rotation curves and some lensing observations without introducing new particles. Its predictive power is good at galactic scales, and it offers a deep geometric motivation for its equations. However, it faces challenges matching CMB and early-universe data. The theory is testable and internally consistent, but its cosmological compatibility is debated.
'''Quasi-Steady State Cosmology (QSSC)''' offers a cyclic, matter-generating model that modifies standard expansion assumptions. It reproduces redshift data through a non-Big Bang framework and introduces a creation field (C) as a new constant. Its empirical adequacy is mixed, and its compatibility with observed element abundances and CMB is questioned. However, its explanatory ambition and falsifiability through periodic structure and matter creation make it a valuable alternative perspective.
'''Dynamic Universe (Tuomo Suntola)''' proposes a zero-energy balance model in which cosmic parameters evolve from a unified dynamic geometry. It predicts H₀ and other constants from time-dependent curvature rather than fixed values. The theory is internally consistent, compact, and provides strong explanatory value for the origin of physical laws. Its compatibility with relativity is nonstandard but mathematically consistent. Observational tests are possible through detailed cosmological reconstructions and time-scaling relationships.
=== '''7.6 – AI Evaluation Based on Shared Criteria''' ===
This subsection presents an AI-assisted comparative evaluation of cosmological theories, based on the shared criteria defined in [[AI-Assisted_Evaluation_of_Cosmological_Theories/Chapter_1:_Introduction_and_Evaluation_Criteria#1.3:_List_of_Evaluation_Criteria|Chapter 1.3: List of Evaluation Criteria]]. The goal is to clarify how each theory treats the fundamental cosmological parameters and universal constants discussed in this chapter. The evaluation highlights '''internal coherence''', '''empirical alignment''', '''explanatory ambition''', and '''potential testability'''.
No star ratings are assigned here. Instead, each theory is qualitatively assessed across the criteria through short descriptive paragraphs.
'''ΛCDM (Standard Model)''' offers '''strong empirical alignment''' with CMB, supernova, and large-scale structure data. Its '''internal structure''' is based on general relativity and well-developed mathematical models, making it '''logically robust'''. However, it provides '''limited explanation''' for the specific values of constants such as H₀ or Λ, which are treated as '''empirical inputs'''. Despite this, it demonstrates '''predictive success''' across multiple observations. The model is '''conceptually economical''', relying on a '''minimal parameter set''', and is '''deeply integrated''' into the broader framework of modern physics. Known tensions (e.g., H₀ discrepancy) invite refinement or reinterpretation but do not undermine its overall compatibility with data. It remains '''broadly testable''' through increasingly precise cosmological measurements.
'''Modified Gravity (f(R))''' theories attempt to explain dark energy and acceleration through '''extensions of the Einstein-Hilbert action'''. They offer a '''reinterpretation of cosmic parameters''' in terms of curvature dynamics rather than exotic energy components. These models vary widely in structure and '''observational fit''', depending on the chosen function f(R), but many reproduce key cosmological features. Their '''mathematical framework''' is internally consistent, and they contribute meaningfully to the debate on the '''nature of gravity'''. While their explanatory power is promising, some formulations require '''additional parameters or fine-tuning'''. Compatibility with '''structure formation data''' and '''gravitational lensing tests''' remains an important area for empirical evaluation.
'''MOND / TeVeS''' seeks to account for galactic rotation curves without invoking dark matter, introducing a '''critical acceleration scale''' as a new constant. It performs '''very well at galactic scales''', offering a direct fit to rotation data. However, it faces '''challenges''' when applied to cosmological phenomena such as the '''cosmic microwave background''' and '''large-scale structure'''. The theory’s internal dynamics are '''logically constructed''' and '''mathematically consistent''' within their range of application. Its '''predictive capacity''' is constrained to specific regimes, and it introduces '''conceptual simplicity''' with '''minimal new constants'''. '''Empirical tensions''' with high-redshift data suggest the need for further development or '''hybrid models'''.
'''Emergent Gravity (Verlinde)''' offers an '''innovative theoretical framework''' in which gravity and inertia '''emerge from entropic and information-theoretic principles'''. This model reframes fundamental constants as '''emergent properties''' of underlying entropy distributions. While its internal structure is '''elegant''' and '''conceptually coherent''', '''empirical validation''' remains limited. It has provided '''tentative fits''' to certain lensing effects, but '''full cosmological modeling''' is still in development. The theory’s '''explanatory reach''' is broad, particularly in redefining Λ and inertia, though specific '''quantitative predictions''' are still rare. It is '''testable in principle''', and future '''observational probes''' could refine or challenge its foundational assumptions.
'''Cosmic Influx Theory (CIT)''' proposes that the '''gravitational constant''' and '''Hubble parameter''' derive from a '''continuous influx of energy into matter'''. It uses the '''relativistic factor (γ−1)''' and a '''universal root mean square velocity (VRMS)''' to derive G and H₀, aligning with '''Planck observations''' without parameter fitting. The theory is '''internally consistent''' and offers '''strong explanatory coherence''' for the emergence of constants. Although it does not define all standard cosmological parameters, its introduction of '''scaling constants''' (κ and κ_CIT) provides a '''novel interpretation''' of structure and '''mass-energy evolution'''. The theory is '''open to falsification''' through predictions on '''orbital dynamics''' and '''preferred planetary distances''', and invites new observational research.
'''Spiral Cosmology''' describes the evolution of the universe through '''organized spiraling flows''' of energy and matter. It offers a '''dynamic interpretation''' of cosmic structure and attempts to '''derive constants''' from the geometry of spiral motion. Its explanatory framework is '''creative and unified''', though primarily '''qualitative''' at this stage. '''Observational alignment''' is still under development, and '''quantitative predictions''' remain limited. The model maintains '''internal coherence''' and offers '''potential compatibility''' with both '''geometric''' and '''wave-based models''' of the universe. It presents a '''unique lens''' on cosmic evolution and may be tested through '''pattern recognition''' in galactic distributions and background structure.
'''Topological Field Framework (Hall)''' attempts to explain the '''emergence of physical constants''' and structure from the '''topology of underlying fields'''. It replaces '''fixed constants''' with '''dynamic relationships''' determined by higher-dimensional field configurations. This theory is '''conceptually ambitious''' and '''mathematically coherent''' within its proposed framework. While it currently lacks '''detailed empirical predictions''', it offers a '''strong explanatory model''' for the origin of constants such as G and c. The framework’s future success depends on its ability to '''generate testable consequences''' and interface with '''observational cosmology'''.
'''Conformal Gravity (Mannheim–Kazanas)''' modifies general relativity using '''conformal symmetry''' and has had success fitting '''galactic rotation curves''' without dark matter. It interprets '''cosmic acceleration''' and '''gravitational potentials''' without requiring Λ or exotic matter components. The theory’s structure is '''mathematically rigorous''' and '''geometrically elegant'''. While it fits some astrophysical data well, its '''compatibility with the CMB''' and '''early universe''' remains under scrutiny. It provides a '''deeper explanation''' for gravitational behavior, but requires additional work to extend to full cosmological predictions. It is '''empirically testable''' and offers a '''valuable challenge''' to conventional dark matter models.
'''Quasi-Steady State Cosmology (QSSC)''' revives and modifies the steady-state model by introducing a '''continuous creation field (C-field)''' and '''cyclic cosmological evolution'''. It offers an '''alternative interpretation''' of redshift and cosmic expansion that challenges the Big Bang model. The theory '''aligns with some observational patterns''' but struggles to reproduce others, such as the '''CMB spectrum''' and '''light element abundances'''. Its internal logic is '''self-consistent''' within its paradigm and introduces an '''original approach''' to '''matter generation''' and '''cosmic cycles'''. QSSC provides '''testable ideas''', particularly related to '''periodicity''' and '''structural evolution''', but remains '''outside the mainstream''' due to its divergence from accepted data interpretations.
'''Dynamic Universe (Tuomo Suntola)''' introduces a '''zero-energy cosmological model''' in which space, time, and matter evolve from a '''dynamically balanced 4-sphere geometry'''. This framework offers a '''coherent mathematical structure''' with an explicit '''derivation of H₀''' and other constants from '''curvature and motion''', rather than treating them as empirical inputs. It avoids the need for '''inflation''', '''dark energy''', or '''dark matter''' by reinterpreting cosmic expansion. The model’s '''internal consistency''' is strong, and its '''elegance''' lies in its '''unified geometric logic'''. '''Testable consequences''' emerge through its '''time-scaling formulations''' and '''reconstruction of historical cosmic dynamics''', providing a fertile ground for further research.
=== '''7.7 – Helicopter View – Scientific Reception and Emerging Tensions''' ===
This subsection offers a broader reflection on how the theories presented in Chapter 7 are received within the scientific community, and how ongoing observational tensions and theoretical gaps have shaped the landscape of cosmological research. While the '''ΛCDM model''' remains the dominant paradigm, persistent anomalies and the rise of innovative frameworks have stimulated growing interest in alternatives that offer novel interpretations of cosmological parameters and universal constants.
The '''ΛCDM model''' has achieved widespread acceptance due to its empirical success in matching high-precision data from the Planck satellite, baryon acoustic oscillations, and Type Ia supernovae. Its internal consistency and predictive utility are widely recognized. However, the model also leaves several foundational questions unresolved. Chief among these is the origin and nature of the '''cosmological constant (Λ)''', which contributes over 68% of the energy density of the universe and yet remains theoretically unexplained. Furthermore, the persistent disparity between early-universe (CMB-derived) and late-universe (distance ladder) measurements of the '''Hubble constant (H₀)''' has become known as the '''"Hubble tension"'''. Similar discrepancies related to the amplitude of matter clustering ('''σ₈''') have raised additional concerns about potential missing physics.
These tensions have opened a window for the exploration of '''non-mainstream cosmologies'''. '''Modified gravity models''' such as '''f(R)''' and '''conformal gravity''' offer geometric alternatives that attempt to reproduce cosmic acceleration and structure formation without invoking dark energy or dark matter. While these models often require additional functions or parameters, they are gaining attention for their potential to resolve observational anomalies through new mathematical structures.
Theories such as '''MOND''', '''TeVeS''', and '''emergent gravity''' have had mixed receptions. '''MOND''' has provided compelling fits to galactic rotation curves but lacks a fully developed cosmological extension. '''Emergent gravity''' introduces a radically different ontology—treating gravity and inertia as statistical phenomena—which appeals to theorists seeking deeper unifying principles. Nonetheless, these theories face strong skepticism from mainstream cosmologists due to limited empirical validation and difficulties in reproducing CMB anisotropies and structure growth data.
The inclusion of conceptual models such as '''Spiral Cosmology''', '''Cosmic Influx Theory (CIT)''', and the '''Dynamic Universe''' represents a growing movement within the scientific periphery to explore frameworks that derive cosmological constants from deeper principles—be they geometric, energetic, or topological. These models often operate outside the dominant institutional research programs, yet they reflect a longstanding scientific aspiration: to understand not only how the universe behaves, but why the constants that govern its behavior take the values they do.
Institutional acceptance of these models varies widely. Peer-reviewed publications remain limited for some, while others circulate primarily via academic repositories, conferences, or platforms such as '''Zenodo''', '''ResearchGate''', or '''Wikiversity'''. This reflects a broader tension in the scientific ecosystem: while mainstream paradigms are highly productive and empirically successful, they may not fully accommodate unconventional but potentially insightful hypotheses.
In this context, the '''AI-assisted comparative framework''' applied in this chapter aims to foster transparent, criteria-based evaluation of both accepted and emerging theories. By focusing on '''empirical adequacy''', '''internal logic''', and '''explanatory potential'''—rather than academic consensus alone—this approach supports a more inclusive and methodologically consistent cosmological discourse.
=== '''7.8 – Next Steps''' ===
This final subsection outlines recommended next steps for researchers, contributors, and interested readers following the comparative evaluation of cosmological parameters and universal constants in Chapter 7.
First, contributors are encouraged to refine or expand the theory entries presented here by improving clarity, adding new references, or providing updated observational data. As ongoing missions such as the '''James Webb Space Telescope (JWST)''', '''Euclid''', and the '''Vera Rubin Observatory''' generate increasingly precise cosmological measurements, all models—mainstream and alternative—will face new opportunities for testing and validation. Particular attention should be paid to how each theory addresses current tensions, including the '''Hubble tension''', the '''σ₈ clustering discrepancy''', and the unexplained nature of '''Λ (dark energy)'''.
Second, AI-assisted comparative tools may be developed further to support large-scale cross-analysis of parameter predictions and internal consistencies. This could include algorithmic comparison of theory-derived parameter sets against datasets from Planck, SDSS, DESI, or gravitational wave observatories. Readers or institutions with expertise in computational cosmology are invited to explore these possibilities and report outcomes.
Third, alternative frameworks that derive constants from first principles—whether geometric, entropic, influx-based, or topological—may benefit from collaborative dialogue. Theories such as '''CIT''', '''Spiral Cosmology''', and the '''Dynamic Universe''' propose unorthodox but structured ways to reinterpret physical constants. These models can be further explored, modified, or combined in search of converging predictions.
Finally, this chapter should remain a living document. As the boundaries of cosmology continue to evolve, Wikiversity provides an open-access platform for iterative updates, interdisciplinary integration, and transparent evaluation. Contributors from all scientific backgrounds are welcome to propose revisions, submit new models, or refine the criteria used here. The comparative structure established in Chapter 7 will also serve as a foundation for deeper synthesis in [[AI-Assisted_Evaluation_of_Cosmological_Theories/Chapter_8:_Critical_Evaluation_and_Future_Research_Paths|Chapter 8]], where star ratings, meta-evaluations, and future research priorities will be formally proposed.

== '''Chapter 8: Methods, Tools, and AI-Assisted Evaluation''' =
== '''8.1 Purpose''' ==
This chapter describes the methodological foundations of the project, including the role of AI in evaluating theories, how contributors interact with the system, and how assessments are recorded, displayed, and updated.
== '''8.2 Toolchain and Workflow''' ==
AI tools like ChatGPT are used to analyze, compare, and refine theories
Tables and frameworks are generated collaboratively using open formats
Contributors submit input via email or editing suggestions
Ratings and evaluations are dynamically updated based on ongoing analysis
== '''8.3 AI-Based Rating System: Motivation and Procedure''' ==
To support comparative evaluation without personal or institutional bias, this project uses an AI-based rating system. ChatGPT acts as a neutral evaluator, analyzing each theory across clearly defined criteria in '''8.5 Understanding the Star Ratings'''.
This system is designed to be:
Transparent – Each rating is justified through AI’s large-scale reference analysis.
Dynamic – Contributors may submit additional materials to request re-evaluation.
Consistent – All evaluations are performed by the same AI logic, eliminating personal bias.
Contributors may ask ChatGPT to re-read specific articles, datasets, or theoretical arguments. If new insights are found, ratings will be updated and transparently noted.
This approach represents a shift toward evidence-driven, large-scale comparative review, using AI not as a gatekeeper but as a tool to synthesize and validate.
== '''8.4 Open Participation''' ==
This chapter is also where future documentation of the workflow and collaborative mechanisms will be expanded. Users who submit theories are encouraged to:
Describe their framework in terms of assumptions, predictions, and compatibility
Suggest how their model could be tested or falsified
Provide references or original materials for AI evaluation
All analysis is open, and contributors may propose improvements at any time.
== '''8.5 Understanding the Star Ratings''' ==
The AI Evaluation Table below rates theories across seven scientific criteria defined in '''Chapter 1.3'''. Here we provide a full explanation of what each criterion means and how it is applied.
'''8.5.1. Empirical Adequacy'''
Does the theory fit known observations and experimental data? High scores require support from astronomy, cosmology, geology, or lab-based physics. Theories that contradict established measurements or lack empirical grounding score lower.
'''8.5.2. Internal Consistency'''
Are the theory’s assumptions, mathematics, and logic self-coherent? A consistent theory does not contain contradictions, undefined steps, or ad hoc assumptions.
'''8.5.3. Predictive Power'''
Does the theory make clear, testable predictions that distinguish it from others? Theories that anticipate new phenomena or retrodict known data gain higher ratings.
'''8.5.4. Cross-Disciplinary Compatibility'''
Is the theory consistent with findings from other scientific fields, such as geology, chemistry, biology, or planetary science? The more compatible it is, the higher the score.
'''8.5.5. Conceptual Clarity and Simplicity'''
Is the theory logically simple and intuitively understandable, without unnecessary complexity? This criterion rewards elegance, not oversimplification.
'''8.5.6. Heuristic Value'''
Does the theory stimulate new questions, research directions, or rethinking of existing problems? A high score reflects creative scientific potential.
'''8.5.7. Historical and Philosophical Insight'''
Does the theory connect meaningfully to the historical development of science or reflect philosophical depth? Theories grounded in tradition or conceptual evolution are valued here.
Each theory receives a rating from ★☆☆☆☆ to ★★★★★ per criterion. The total score (max 35) gives a general measure of its scientific coherence and reach. The reasoning behind the scores is available under each theory or can be requested in more detail.
=== '''8.6 AI Evaluation Table Format''' ===

== '''8.7 Requesting Detailed Justification''' ==
“Somebody” interested in the full motivation for a theory’s score—criterion by criterion—can obtain this by:
1. Visiting the '''discussion page''' of this Wikiversity chapter.
2. Mentioning the theory by name and explicitly asking for the detailed breakdown.
3. Receiving an AI-generated or authored comment elaborating why each star rating was assigned.
These ratings are transparent and intended to support critical evaluation and ongoing refinement of both established and alternative cosmological theories. Constructive feedback, new data, or arguments may lead to adjustments in the scores, provided clear reasoning is presented.
If a contributor or author does not agree with the evaluation or prefers not to have their theory represented under this framework, they may request that all related content and ratings for that theory be removed. This ensures that participation remains voluntary and respectful of intellectual ownership.
'''Mainstream theories are subject to the same critical standard.'''
If someone presents a reasoned objection to the current star ratings of a widely accepted theory (e.g. General Relativity, Big Bang), their explanation will be reviewed. If the argument is well-founded, ChatGPT may generate a revised evaluation. Both the original and alternative viewpoints can be documented transparently if needed.
If you want to submit a '''Rating Rebuttal''', please use the template provided on the '''[[Talk:AI-Assisted Evaluation of Cosmological Theories|Discussion page]]'''.
== '''8.8 Detailed Evaluations of Theories''' ==
This section will be expanded progressively as new theories are added. Each evaluation is generated in collaboration with ChatGPT, based on a standardized set of seven criteria defined in Chapter 1. This approach allows for clear, consistent, and rapid assessment of both mainstream and non-mainstream cosmological theories within minutes.

== '''Chapter 8: Methods, Tools, and AI-Assisted Evaluation''' =
== '''8.1 Purpose''' ==
This chapter describes the methodological foundations of the project, including the role of AI in evaluating theories, how contributors interact with the system, and how assessments are recorded, displayed, and updated.
== '''8.2 Toolchain and Workflow''' ==
AI tools like ChatGPT are used to analyze, compare, and refine theories
Tables and frameworks are generated collaboratively using open formats
Contributors submit input via email or editing suggestions
Ratings and evaluations are dynamically updated based on ongoing analysis
== '''8.3 AI-Based Rating System: Motivation and Procedure''' ==
To support comparative evaluation without personal or institutional bias, this project uses an AI-based rating system. ChatGPT acts as a neutral evaluator, analyzing each theory across clearly defined criteria in '''8.5 Understanding the Star Ratings'''.
This system is designed to be:
Transparent – Each rating is justified through AI’s large-scale reference analysis.
Dynamic – Contributors may submit additional materials to request re-evaluation.
Consistent – All evaluations are performed by the same AI logic, eliminating personal bias.
Contributors may ask ChatGPT to re-read specific articles, datasets, or theoretical arguments. If new insights are found, ratings will be updated and transparently noted.
This approach represents a shift toward evidence-driven, large-scale comparative review, using AI not as a gatekeeper but as a tool to synthesize and validate.
== '''8.4 Open Participation''' ==
This chapter is also where future documentation of the workflow and collaborative mechanisms will be expanded. Users who submit theories are encouraged to:
Describe their framework in terms of assumptions, predictions, and compatibility
Suggest how their model could be tested or falsified
Provide references or original materials for AI evaluation
All analysis is open, and contributors may propose improvements at any time.
== '''8.5 Understanding the Star Ratings''' ==
The AI Evaluation Table below rates theories across seven scientific criteria defined in '''Chapter 1.3'''. Here we provide a full explanation of what each criterion means and how it is applied.
'''8.5.1. Empirical Adequacy'''
Does the theory fit known observations and experimental data? High scores require support from astronomy, cosmology, geology, or lab-based physics. Theories that contradict established measurements or lack empirical grounding score lower.
'''8.5.2. Internal Consistency'''
Are the theory’s assumptions, mathematics, and logic self-coherent? A consistent theory does not contain contradictions, undefined steps, or ad hoc assumptions.
'''8.5.3. Predictive Power'''
Does the theory make clear, testable predictions that distinguish it from others? Theories that anticipate new phenomena or retrodict known data gain higher ratings.
'''8.5.4. Cross-Disciplinary Compatibility'''
Is the theory consistent with findings from other scientific fields, such as geology, chemistry, biology, or planetary science? The more compatible it is, the higher the score.
'''8.5.5. Conceptual Clarity and Simplicity'''
Is the theory logically simple and intuitively understandable, without unnecessary complexity? This criterion rewards elegance, not oversimplification.
'''8.5.6. Heuristic Value'''
Does the theory stimulate new questions, research directions, or rethinking of existing problems? A high score reflects creative scientific potential.
'''8.5.7. Historical and Philosophical Insight'''
Does the theory connect meaningfully to the historical development of science or reflect philosophical depth? Theories grounded in tradition or conceptual evolution are valued here.
Each theory receives a rating from ★☆☆☆☆ to ★★★★★ per criterion. The total score (max 35) gives a general measure of its scientific coherence and reach. The reasoning behind the scores is available under each theory or can be requested in more detail.
=== '''8.6 AI Evaluation Table Format''' ===
This table presents a side-by-side comparison of cosmological theories based on the AI-assisted ratings across seven criteria. The ratings are qualitative estimates based on literature synthesis, theory structure, and conceptual coherence.

''Note:'' Star ratings (★) reflect relative performance across seven shared evaluation criteria, as explained in [[#8.5 Understanding the Star Ratings|Section 8.5]].
'''In subsection 8.8 you find a detailed motivation from ChatGPT for the star ratings.'''
<!-- Add a blank line here -->
== '''8.7 Requesting Detailed Justification''' ==
“Somebody” interested in the full motivation for a theory’s score—criterion by criterion—can obtain this by:
1. Visiting the '''discussion page''' of this Wikiversity chapter.
2. Mentioning the theory by name and explicitly asking for the detailed breakdown.
3. Receiving an AI-generated or authored comment elaborating why each star rating was assigned.
These ratings are transparent and intended to support critical evaluation and ongoing refinement of both established and alternative cosmological theories. Constructive feedback, new data, or arguments may lead to adjustments in the scores, provided clear reasoning is presented.
If a contributor or author does not agree with the evaluation or prefers not to have their theory represented under this framework, they may request that all related content and ratings for that theory be removed. This ensures that participation remains voluntary and respectful of intellectual ownership.
'''Mainstream theories are subject to the same critical standard.'''
If someone presents a reasoned objection to the current star ratings of a widely accepted theory (e.g. General Relativity, Big Bang), their explanation will be reviewed. If the argument is well-founded, ChatGPT may generate a revised evaluation. Both the original and alternative viewpoints can be documented transparently if needed.
If you want to submit a '''Rating Rebuttal''', please use the template provided on the '''[[Talk:AI-Assisted Evaluation of Cosmological Theories|Discussion page]]'''.
== '''8.8 Detailed Evaluations of Theories''' ==
This section will be expanded progressively as new theories are added. Each evaluation is generated in collaboration with ChatGPT, based on a standardized set of seven criteria defined in Chapter 1. This approach allows for clear, consistent, and rapid assessment of both mainstream and non-mainstream cosmological theories within minutes.

''Note:'' Star ratings (★) reflect relative performance across seven shared evaluation criteria, as explained in [[#8.5 Understanding the Star Ratings|Section 8.5]].
'''In subsection 8.8 you find a detailed motivation from ChatGPT for the star ratings.'''
<!-- Add a blank line here -->
== '''8.7 Requesting Detailed Justification''' ==
“Somebody” interested in the full motivation for a theory’s score—criterion by criterion—can obtain this by:
1. Visiting the '''discussion page''' of this Wikiversity chapter.
2. Mentioning the theory by name and explicitly asking for the detailed breakdown.
3. Receiving an AI-generated or authored comment elaborating why each star rating was assigned.
These ratings are transparent and intended to support critical evaluation and ongoing refinement of both established and alternative cosmological theories. Constructive feedback, new data, or arguments may lead to adjustments in the scores, provided clear reasoning is presented.
If a contributor or author does not agree with the evaluation or prefers not to have their theory represented under this framework, they may request that all related content and ratings for that theory be removed. This ensures that participation remains voluntary and respectful of intellectual ownership.
'''Mainstream theories are subject to the same critical standard.'''
If someone presents a reasoned objection to the current star ratings of a widely accepted theory (e.g. General Relativity, Big Bang), their explanation will be reviewed. If the argument is well-founded, ChatGPT may generate a revised evaluation. Both the original and alternative viewpoints can be documented transparently if needed.
If you want to submit a '''Rating Rebuttal''', please use the template provided on the '''[[Talk:AI-Assisted Evaluation of Cosmological Theories|Discussion page]]'''.
== '''8.8 Detailed Evaluations of Theories''' ==
This section will be expanded progressively as new theories are added. Each evaluation is generated in collaboration with ChatGPT, based on a standardized set of seven criteria defined in Chapter 1. This approach allows for clear, consistent, and rapid assessment of both mainstream and non-mainstream cosmological theories within minutes.

Medical emergencies occur anywhere, at any time, in any country irrespective of whether it is a developed, developing or an underdeveloped country. These emergencies occur by the hour, consuming a lot of resources and sometimes, without even achieving the desired results, i.e., to save lives. Medical emergencies have been around since the start of the human civilization, however, they gained recognition as a specialty only around 30 years ago (Chung, 2001). An emergency medical system’s goal should be to provide universal and integrative emergency care right from the time it receives information from an emergency user (Dykstra, E. H, 1997). Further, in a country like India, the seventh largest country, and with the second highest population in the world (David, S. S., & Vasnaik, M, 2007) and high income disparity, the implementation and context of the emergency medical system should be in a way to increase health equity and not worsen the current health disparities (David, S. S., & Vasnaik, M, 2007). This challenge faced by India and similar developing nations can be attended to by promoting systematic development of an evidence-based emergency medical system that is more cost effective than those in developed countries like the USA, Canada and certain European countries where there is lesser income disparity. To design an effective emergency medical system, there is need to address questions such as how it would integrate with the current health-care infrastructure, local communities as well as their values, and the financial resources that would be needed to augment the services step by step (Gupta, M. Das, & Rani, M. 2004). In India, the public sector accounts for less than 20 percent of the total healthcare expenditure, which is the lowest in the world, and is less than 1% of the country’s GDP (KPMG, 2005). Around 94% of the amount of private expenditure is from out of the pockets of citizens, and the remaining 6% is the provision’s expenditure (Development Bank A, 2015). The way forward for the government to address this challenging situation is to consider the Public Private Partnerships (PPP) model in the emergency healthcare sector in India. The emergence v of PPP in India has provided a viable solution wherein the government-led public sector forms a synergetic partnership with the technically advanced and innovative private sector (Raman, A.V et al., 2008). In emergency medical services, the government set-up 108 partnerships in 2005 (Besley, T., & Ghatak, M. 2017) with private organizations, such as GVK, Ziqitza Health Care Ltd., to deal with fatal emergencies, for example, dealing with the medical emergency during the Fani cyclone1 at Odisha in 2019. However, the emergency services are fragmented in India (Subhan, I., & Jain, A. 2010), with many private services having entered the arena without regulation. Though this may look to be a good social and altruistic sign, in the long run, it would hamper the progress of emergency services across the country. These questions will be well-addressed in this study when the rationality of promoting the emergency service systems is evaluated from the financing point of view. Further, in this study, we model the PPP contracts in accordance with the government’s plan to integrate emergency services inclusive of fire and police with emergency health services under a common emergency telephone number, 112. Evidence is available to show that several roles, strategies, rules, and pay-offs govern procedures in the partnerships between the public sector and private firms (Bettignies, J.-E. de, & Ross, T. W, 2004). Thus, modeling them as complex games can help to better understand the failures and difficulties in such partnerships (Scharle, 2002). In this context, the researchers are implementing Nash bargain solutions in their research works to understand financial renegotiations (De Brux, J. 2010). However, there are very few studies to understand why financial renegotiation between government and service provider fails in a PPP contract. Through this study, we hope to provide a solid foundation to the integrated emergency medical services, which in turn, would provide Indian citizens the same equity, access, and quality of services which have been enjoyed by the people in the developing countries for decades. 1Fani cyclone hit many parts of Odisha in April- May of 2019, article by Vishwa Mohan (May 4, 2019), Times of India. vi In the first essay, we have modeled funding mechanisms for Profit-based (Corporate) service providers to provide emergency medical services in PPP during natural disasters such as cyclones and tsunamis or pandemic-like situations such as Covid-19 when there is an unprecedented increase in demand of this service provision. In the second situation, that is, pandemic-like situations, we have considered modeling conditions when the service provider is successful in renegotiating with the government as well as when renegotiation is unsuccessful and investor goes ahead with the funding under government intervention.. Insights from the study indicate that government underinvests during regular situations, whereas during situations which require unprecedented rise in demand, it needs to monitor the service providers to prevent moral hazards. In the second essay, we have modeled funding mechanisms for non-profit-based (NGO) service providers under similar conditions as in the first essay. Further, in case of an unprecedented rise of demand, we have restricted to modeling in renegotiation, as the case of renegotiation failure does not occur in case of non-profit-based service providers. Insights from the study show that the government has preference for investing in non-profit service providers as their pay-off increases with the payoff of the non-profit service provider (SP). In the final essay, we have modeled advertising as a signal to convey the type of service provider (profit/non-profit) to the citizens (/Users/Patients); and also help the service providers decide their service provision. The study reveals that in regular situations, the advertisement strategy may aid to serve the patients when they require the emergency services. Further, the government may prefer either of the SPs (Profit-Oriented or Non-Profit-Oriented) to provide better payoffs in the PPP contractual relationship. We find that the government needs to incentivize service providers to attain demand /service realization. Alternatively, it can penalize service providers by formulating policies if the effort vii decreases with an increase in investment, as in few scenarios. Further, in all scenarios the government needs to formulate policies that aid investment in insurance companies so that citizens have to make less “out of pockets payments” that are quite expensive in emerging economies like India. Though insurance schemes have been launched by the central government in the past few years, various states that have been in PPP -based contracts for emergency health services need to coordinate with the centre to launch more innovative insurance schemes to reduce “out of pocket" expenses” thereby, improving citizen’s welfare. viii{{Article info

Medical emergencies occur anywhere, at any time, in any country irrespective of whether it is a developed, developing or an underdeveloped country. These emergencies occur by the hour, consuming a lot of resources and sometimes, without even achieving the desired results, i.e., to save lives. Medical emergencies have been around since the start of the human civilization, however, they gained recognition as a specialty only around 30 years ago (Chung, 2001). An emergency medical system’s goal should be to provide universal and integrative emergency care right from the time it receives information from an emergency user (Dykstra, E. H, 1997). Further, in a country like India, the seventh largest country, and with the second highest population in the world (David, S. S., & Vasnaik, M, 2007) and high income disparity, the implementation and context of the emergency medical system should be in a way to increase health equity and not worsen the current health disparities (David, S. S., & Vasnaik, M, 2007). This challenge faced by India and similar developing nations can be attended to by promoting systematic development of an evidence-based emergency medical system that is more cost effective than those in developed countries like the USA, Canada and certain European countries where there is lesser income disparity. To design an effective emergency medical system, there is need to address questions such as how it would integrate with the current health-care infrastructure, local communities as well as their values, and the financial resources that would be needed to augment the services step by step (Gupta, M. Das, & Rani, M. 2004). In India, the public sector accounts for less than 20 percent of the total healthcare expenditure, which is the lowest in the world, and is less than 1% of the country’s GDP (KPMG, 2005). Around 94% of the amount of private expenditure is from out of the pockets of citizens, and the remaining 6% is the provision’s expenditure (Development Bank A, 2015). The way forward for the government to address this challenging situation is to consider the Public Private Partnerships (PPP) model in the emergency healthcare sector in India. The emergence v of PPP in India has provided a viable solution wherein the government-led public sector forms a synergetic partnership with the technically advanced and innovative private sector (Raman, A.V et al., 2008). In emergency medical services, the government set-up 108 partnerships in 2005 (Besley, T., & Ghatak, M. 2017) with private organizations, such as GVK, Ziqitza Health Care Ltd., to deal with fatal emergencies, for example, dealing with the medical emergency during the Fani cyclone1 at Odisha in 2019. However, the emergency services are fragmented in India (Subhan, I., & Jain, A. 2010), with many private services having entered the arena without regulation. Though this may look to be a good social and altruistic sign, in the long run, it would hamper the progress of emergency services across the country. These questions will be well-addressed in this study when the rationality of promoting the emergency service systems is evaluated from the financing point of view. Further, in this study, we model the PPP contracts in accordance with the government’s plan to integrate emergency services inclusive of fire and police with emergency health services under a common emergency telephone number, 112. Evidence is available to show that several roles, strategies, rules, and pay-offs govern procedures in the partnerships between the public sector and private firms (Bettignies, J.-E. de, & Ross, T. W, 2004). Thus, modeling them as complex games can help to better understand the failures and difficulties in such partnerships (Scharle, 2002). In this context, the researchers are implementing Nash bargain solutions in their research works to understand financial renegotiations (De Brux, J. 2010). However, there are very few studies to understand why financial renegotiation between government and service provider fails in a PPP contract. Through this study, we hope to provide a solid foundation to the integrated emergency medical services, which in turn, would provide Indian citizens the same equity, access, and quality of services which have been enjoyed by the people in the developing countries for decades. 1Fani cyclone hit many parts of Odisha in April- May of 2019, article by Vishwa Mohan (May 4, 2019), Times of India. vi In the first essay, we have modeled funding mechanisms for Profit-based (Corporate) service providers to provide emergency medical services in PPP during natural disasters such as cyclones and tsunamis or pandemic-like situations such as Covid-19 when there is an unprecedented increase in demand of this service provision. In the second situation, that is, pandemic-like situations, we have considered modeling conditions when the service provider is successful in renegotiating with the government as well as when renegotiation is unsuccessful and investor goes ahead with the funding under government intervention.. Insights from the study indicate that government underinvests during regular situations, whereas during situations which require unprecedented rise in demand, it needs to monitor the service providers to prevent moral hazards. In the second essay, we have modeled funding mechanisms for non-profit-based (NGO) service providers under similar conditions as in the first essay. Further, in case of an unprecedented rise of demand, we have restricted to modeling in renegotiation, as the case of renegotiation failure does not occur in case of non-profit-based service providers. Insights from the study show that the government has preference for investing in non-profit service providers as their pay-off increases with the payoff of the non-profit service provider (SP). In the final essay, we have modeled advertising as a signal to convey the type of service provider (profit/non-profit) to the citizens (/Users/Patients); and also help the service providers decide their service provision. The study reveals that in regular situations, the advertisement strategy may aid to serve the patients when they require the emergency services. Further, the government may prefer either of the SPs (Profit-Oriented or Non-Profit-Oriented) to provide better payoffs in the PPP contractual relationship. We find that the government needs to incentivize service providers to attain demand /service realization. Alternatively, it can penalize service providers by formulating policies if the effort vii decreases with an increase in investment, as in few scenarios. Further, in all scenarios the government needs to formulate policies that aid investment in insurance companies so that citizens have to make less “out of pockets payments” that are quite expensive in emerging economies like India. Though insurance schemes have been launched by the central government in the past few years, various states that have been in PPP -based contracts for emergency health services need to coordinate with the centre to launch more innovative insurance schemes to reduce “out of pocket" expenses” thereby, improving citizen’s welfare. viii{{Article info
