	Which is better for the web: single vendor homogeneity, or OSS/Web 2.0-style innovation? - The Web Standards Project
		Which is better for the web: single vendor homogeneity, or OSS/Web 2.0-style innovation?
		Pure platform companies fail (MS has Office as well as Windows, and they’re diversifying).
		Platforms are great, but not in isolation.Comment #14 by Brendan Eich on ‘Which is better for the web: single vendor homogeneity, or OSS/Web 2.0-style innovation?’ […]

	Homogeneity - Wikipedia, the free encyclopedia
		The coefficient of the internal consistency reliability and the coefficient of homogeneity for tautologous lattices are both equal to zero.
		Interest in homogeneity of data was revived during the closing decades of the last century by Cliff (1977), and by Krus and Blackman (1988).
		This coefficient of homogeneity is numerically equivalent with both the Loevinger's and Cliff's conceptualizations of the coefficient of homogeneity.

		averaging unit for calculating an average homogeneity value for the first pixel by means of averaging the first homogeneity value and the second homogeneity value; and - a comparing unit for comparing the average homogeneity value with a threshold in order to assign the first pixel to the segment.
		In the segmentation method according to the prior art a homogeneity value is calculated based on pixels of one image: the intensity difference is the gray tone difference between the pixel under consideration and the mean of the pixels that have already been assigned to the region.
		The advantage of calculating a weighted average homogeneity value is that it allows to make a trade-off between a pixel accurate segmentation primarily based on a single image on the one hand and a time stable segmentation on the other hand based on multiple images.

	Homogeneity (physics) - Wikipedia, the free encyclopedia
		In the Lagrangian formalism, homogeneity (in space) implies conservation of momentum, homogeneity in time implies conservation of energy.
		A valid equation in physics must be homogeneous.
		However, if the equation is homogeneous, it doesn't necessarily mean the equation will be true, since it does not take into account numerical factors.

	A Brief Introduction to Homogeneity Analysis (Site not responding. Last check: )
		Homogeneity analysis is the basic technique in the Gifi system [1] of nonlinear multivariate analysis.
		Homogeneity of a set of (centered) variables is measured by computing the sum of squares within objects and the sum of squares between objects.
		A measure of homogeneity is the ratio of the between objects sum of squares to the total sum of squares.

		In sociology, role homogeneity is the degree of overlap amongst the different roles performed by different members of a community.
		Rural sociologists often note that amongst rural communities there exists a very high degree of role homogeneity, that is, one person may perform the duties of banker, coach, deacon, school board member, and neighbor.
		Sociologists have demonstrated that in areas of strong homogeneity, there is a general tendency to repress controversy.

	THE LEGEND OF COSMOLOGICAL HOMOGENEITY
		The envisioned cosmological homogeneity is not a virtually perfect homogeneity such as is found in a pure quartz crystal, but rather is a statistical homogeneity, which becomes more perfect as you increase the size of the observed volume.
		In astrophysics, one basic way to test for the presence of a homogeneous large-scale distribution of matter is to to check one vast volume for an even distribution of matter, radiation or motion.
		The first serious challenge to the assumption of cosmological homogeneity came in the latter half of the 1920s when astronomers confirmed that stars were not homogeneously distributed, but rather were amassed in huge "island universes" which we now call galaxies.

	Data Homogeneity
		Homogeneous data are drawn from a single population.
		Realistically, obtaining perfectly homogeneous data is almost impossible, as unavoidable changes in the area surrounding the observing station will often affect the data.
		Homogeneity can be tested by noting how many runs were present in the sample compared to how many total elements were in the sample.

	Homogeneity (Site not responding. Last check: )
		In systematic reviews homogeneity refers to the degree to which the results of studies included in a review are similar.
		Clinical homogeneity means that, in trials included in a review, the participants, interventions and outcome measures are similar or comparable.
		Studies are considered statistically homogeneous if their results vary no more than might be expected by the play of chance, though most statistical tests would say that 10% of a perfectly homogeneous data set was heterogeneous, because that is the usual set-point for the tests.

	Homogeneity of Variance in One-Way Models
		One of the usual assumptions for the GLM procedure is that the underlying errors are all uncorrelated with homogeneous variances.
		Homogeneity of variance testing for more complex models is a subject of current research.
		The significance level for the test of homogeneity of variance is the p-value for the ANOVA F-test on the dispersion variable.

	homogeneity / hetero (Site not responding. Last check: )
		Homogeneity is seen as a effect of the nation-state as well as global capitalism.
		One of these had to do with unity and "homogeneity," (Geoffroy?) the other with multiplicity and "specification." (Cuvier?) According to Kant, controversies of this sort are incapable of being decided in such a way that one side is proved right or wrong.
		Is there a "homogeneous space of knowledge?" For Panofsky the homogeneous and infinite space of perspective is quite unlike the space given to perception.

	Tests of Marginal Homogeneity
		Various measures of marginal homogeneity would be calculated for each pseudo-table; for example, one might calculate the difference between the row marginal proportion and the column marginal proportion for each category, or construct an overall measure of row vs. column marginal differences.
		First one estimates a general form of the model--that is, one without assuming marginal homogeneity; let this be termed the "unrestricted model." Next one adds the assumption of marginal homogeneity to the model.
		A comparison of this restricted model with the corresponding unrestricted model tests the hypothesis that the fixed constant, which corresponds to bias of a rater, is 0.

	Homogeneity of Mormons
		This study and the Mauss study aren't exactly comparable, but they do give an indication that converts and lifetime members are not homogenous in their propensity to be active in the church.
		While it is true that inactive people have more non-members in their networks to potentially convert, it is also true that, according to the model, any conversions from those referrals will follow the example of the person referring them and go inactive.
		However, this component of the exponential growth of the church is concerned with their homogeneity in their propensity to gain converts, not their appearance and standards.

	IV. Localism, Homogeneity, and Networks
		In "The Work/Energy Crisis" (Caffentzis, 1980), this was expressed metaphorically via physics: increased homogeneity (uniformity, lack of difference) in the working class produces entropy in the capitalist system, resulting in the eventual death of capitalism.
		In political terms, homogeneity means the identity of political interests and hence unity against capital.
		On the one side (not explored here) is the problem of cultural homogeneity produced by capital via such things as mass media on a world scale: the production of an undifferentiated proletarian cultural lump as homogeneity used by capital against the working class.

	McNemar Tests of Marginal Homogeneity
		Since the a and the d on both sides of the equations cancel, this implies b = c; this is the basis of the McNemar test.
		Specifically, to test row/column marginal homogeneity for category k, one collapses all rows and columns corresponding to the other categories.

	ERP 9:1 An Unconditional Likelihood Ratio for Testing Item Homogeneity in the Rasch Model
		Person homogeneity refers to the characteristic of a test model to assume that all persons work on the items of a test on the basis of the same latent ability.
		For the purpose of testing item homogeneity directly, an analogous test is needed, which renders it possible to test whether all items are solved on the basis of one parameter for each person.
		The test of item homogeneity by either an unconditional or a conditional LR test is as strong or as weak as is the grouping of items.

	Curious About Astronomy: What do "homogeneity" and "isotropy" mean?
		Homogeneous is defined as "the same in all locations" while isotropic means "the same in all directions." Imagine that the whole universe is an infinitely large field with one perfectly symmetrical hill, which you are seated atop.
		These concepts are important because most modern cosmology is based on the "cosmological principle," the assumption that, on large scales, the universe is both homogeneous and isotropic.
		Studies of large-scale structure in the universe and analysis of the microwave background radiation help confirm that this assumption is justified.

		To say the Universe is homogeneous means that any measurable property of the Universe is the same everywhere.
		Since the age of the Universe is one of the measurable quantities, the homogeneity of the Universe must be defined on a surface of constant proper time since the Big Bang.
		Current density estimates suggest that the matter density is between 0.2 to 1 times the critical density, and this does require that most of the matter in the Universe is dark.

	High Homogeneity Solenoids
		By high homogeneity, we mean superconducting magnets with better than +/- 0.01% (100 ppm) maximum central field variation over a 10mm diameter spherical volume (DSV).
		This insures homogeneity specification is maintained throughout the entire field range of the superconducting magnet.
		Other applications, such as NMR experimentation, require the superconducting magnet to have 1 ppm or 0.1 ppm homogeneity over a large homogeneous volume.

	Homogeneity and Euler's Theorem
		Phillip Wicksteed (1894) stated the "product exhaustion" thesis implied by the marginal productivity theory of distribution - namely, that if all agents were paid their marginal product, then total costs would exhaust the entire product.
		Wicksteed assumed constant returns to scale - and thus employed a linear homogeneous production function, a function which was homogeneous of degree one.
		(x), are themselves homogeneous functions of degree k-1.

	Encyclopedia Coptica: The Christian Coptic Orthodox Church Of Egypt
		The Coptic community ceased to be regarded by the state as an administrative unit and, by 1855 A.D., the main mark of Copts' inferiority, the "Gezya" tax was lifted, and shortly thereafter Copts started to serve in the Egyptian army.
		The 1919 A.D. revolution in Egypt, the first grassroots dispaly of Egyptian identity in centuries, stands as a witness to the homogeneity of Egypt's modern society with both its Muslim and Coptic sects.
		Today, this homogeneity is what keeps the Egyptian society united against the religious intolerance of extremist groups, who occasionaly subject the Copts to persecution and terror.

	Alexandre Kojève [Internet Encyclopedia of Philosophy] (Site not responding. Last check: )
		Bataille (anthropologist, philosopher and pornographer, a doyen of recent postmodern aestheticism and anti-rationalism) was perhaps the most powerful articulator of Kojève's pessimism in the face of the 'death of man'.
		The victory of reason was, for Bataille, a curse; its inevitable triumph in the unstoppable march of modernity brought with it homogeneity, order, and disenchantment.
		The triumph of reason as history meant the twilight and death of man, as the excessive and destructive power of negativity was displaced by harmonious, reciprocal equilibrium.

	Racial Homogeneity And Social Capital
		This effect is examined by comparing the social capital of the racially homogenous Seattle, Atlanta, and Detroit with the racially diverse Los Angeles, Houston, and Chicago.
		This paper speculates that cities with racial homogeneity will experience higher levels of social capital, as people generally feel more comfortable/trusting of those with whom they share a common bond.
		For better or worse, racial homogeneity is correlated to high social capital and is determined to have a causal effect on the level of a city’s social capital.

	Homogeneity of the Earth's Mantle
		The ‘mantle" as it is called, is detectable by seismic refraction and is a shell of the Earth’s interior extending from a depth of about 20 km below the oceanic crust down to 2900km, or about halfway to the centre of the Earth.
		If a large convection cell is about half the diameter of the earth, the mantle section may have turned over about four to six times, not enough to homogenise the mantle as a whole as the circulatory flow must mainly be laminar rather than turbulent.
		If the original mantle were homogenous then it must have had an MgO content not greater than 37% MgO, as this would ave the lowest partial melting point.
