In this article I will heuristically remove the term Eurocentrism from its negative connotations. I describe Eurocentrism as a structure of, and for, cognition, whose constituent components of rational logic and objectivity continue to have validity for gaining scientific knowledge. Such a view of Eurocentrism starts with the origin of the phenomenon, not with its effects. Further, its driving forces can be detailed, as they ‐ until the present ‐ have been interpreted mostly phenomenologically and not analytically. Here, Eurocentrism shall be defined as a phenomenon that, across space and time, has become a productive force for the development of man and nature from the Enlightenment to the present day. 相似文献

In the debate on globalisation and wage inequality within countries, Heckscher–Ohlin theory has featured prominently, yet fails to take into account that globalisation comprises much more than increased trade between advanced and less-advanced countries. This paper develops a framework that takes better heed of the many aspects of globalisation and thereby addresses a new channel through which globalisation might influence wage inequality. Our results indicate that to understand the impact of globalisation on wage inequality, one needs insight in the nature and stage of globalisation and the relative size of a country. 相似文献

Two distinctly different quantitative approaches are used to evaluate measurement instruments: the split‐ballot experiment and the multitrait‐multimethod (MTMM) approach. The first approach is typically used to indicate whether variation in the method causes differences in the response distribution; the second approach evaluates the reliability and validity of different methods. The new approach, suggested in this paper, combines the more attractive features of both methods. The strength of the split‐ballot experiment is its use of independent random samples from the same population to provide information about differences in response distributions. This is also possible with the new approach, but this approach provides more detailed information about the reasons for the differences. The MTMM approach provides information about reliability and validity on the basis of repeated observation of the same traits using different methods. This information is also provided by the new design. The difference is that the new approach reduces the need for repeated observations of the same trait. Each sample is provided with a different combination of only two methods and the complete model with all methods is estimated as a multiple‐group model. This reduces the burden for respondents and also reduces memory and order effects. Alternative designs and estimation methods are discussed, their efficiency is analyzed, and illustrations are provided . 相似文献

The theory of best affine prediction (BAP) is extended to the vector case with possibly singular variance matrix of the predictor
variable. The theory is then applied to derive Thomson’s classical predictor for factor scores, allowing for a singular variance
matrix of the factors. The results are formulated in a free distribution setting. Further, Bartlett’s estimator is considered
and compared with Thomson’s predictor.

This paper assesses the ways in which the availability of family planning program outlets influences the likelihood of contraceptive use in rural Thailand. It focuses on a village-level measure of actual availability of sources rather than respondent perceptions of availability. Individuallevel and village-level data collected as part of the second Thailand Contraceptive Prevalence Survey are used to test three hypotheses about the effects of actual availability: that (a) availability of family planning outlets increases the likelihood of contraceptive use; (b) it enhances the effect of a desire for no more children on the likelihood of use; and (c) it weakens the positive relationship between education and the likelihood of use. 相似文献

The future of federal support for sociology (and the other social sciences) will depend on the continued mobilization efforts
of COSSA and upon public recognition of sociological contributions to the realization of two prime sets of values. Sociology
can best affect this future by improving its record of visibly effective work in pursuit of the larger public interest. 相似文献

A model for directional data in q dimensions is studied. The data are assumed to arise from a distribution with a density on a sphere of q — 1 dimensions. The density is unimodal and rotationally symmetric, but otherwise of unknown form. The posterior distribution of the unknown mode (mean direction) is derived, and small-sample posterior inference is discussed. The posterior mean of the density is also given. A numerical method for evaluating posterior quantities based on sampling a Markov chain is introduced. This method is generally applicable to problems involving unknown monotone functions. 相似文献

Summary. We introduce a new, hierarchical, model for single-nucleotide polymorphism allele frequencies in a structured population, which is naturally fitted via Markov chain Monte Carlo methods. There is one parameter for each population, closely analogous to a population-specific version of Wright's F ST , which can be interpreted as measuring how isolated the relevant population has been. Our model includes the effects of single-nucleotide polymorphism ascertainment and is motivated by population genetics considerations, explicitly in the transient setting after divergence of populations, rather than as the equilibrium of a stochastic model, as is traditionally the case. For the sizes of data set that we consider the method provides good parameter estimates and considerably outperforms estimation methods analogous to those currently used in practice. We apply the method to one new and one existing human data set, each with rather different characteristics—the first consisting of three rather close European populations; the second of four populations taken from across the globe. A novelty of our framework is that the fit of the underlying model can be assessed easily, and these results are encouraging for both data sets analysed. Our analysis suggests that Iceland is more differentiated than the other two European populations (France and Utah), a finding which is consistent with the historical record, but not obvious from comparisons of simple summary statistics. 相似文献
