Uniform Test Assembly

In educational practice, a test assembly problem is formulated as a system of inequalities induced by test specifications. Each solution to the system is a test, represented by a 0–1 vector, where each element corresponds to an item included (1) or not included (0) into the test. Therefore, the size of a 0–1 vector equals the number of items n in a given item pool. All solutions form a feasible set—a subset of 2 ⁿ vertices of the unit cube in an n-dimensional vector space. Test assembly is uniform if each test from the feasible set has an equal probability of being assembled. This paper demonstrates several important applications of uniform test assembly for educational practice. Based on Slepian’s inequality, a binary program was analytically studied as a candidate for uniform test assembly. The results of this study establish a connection between combinatorial optimization and probability inequalities. They identify combinatorial properties of the feasible set that control the uniformity of the binary programming test assembly. Computer experiments illustrating the concepts of this paper are presented.     

The enemy between us: The psychological and social costs of inequality

There is now substantial evidence that larger income differences in a society increase the prevalence of most of the health and social problems that tend to occur more frequently lower down the social ladder. The pathways through which human beings are sensitive to inequality are however less clear. This paper outlines the explanatory theory that we think best fits the growing but incomplete body of evidence available. Inequality appears to have its most fundamental effects on the quality of social relations—with implications affecting the prevalence of a number of psychopathologies. We suggest that human beings have two contrasting evolved social strategies: one that is adaptive to living in a dominance hierarchy and the other appropriate to more egalitarian societies based on reciprocity and cooperation. Although both strategies are used in all societies, we hypothesise that the balance between them changes with the extent of material inequality.     

Bayesian Estimation of Circumplex Models Subject to Prior Theory Constraints and Scale-Usage Bias

This paper presents a hierarchical Bayes circumplex model for ordinal ratings data. The circumplex model was proposed to represent the circular ordering of items in psychological testing by imposing inequalities on the correlations of the items. We provide a specification of the circumplex, propose identifying constraints and conjugate priors for the angular parameters, and accommodate theory-driven constraints in the form of inequalities. We investigate the performance of the proposed MCMC algorithm and apply the model to the analysis of value priorities data obtained from a representative sample of Dutch citizens. We wish to thank Michael Browne and two anonymous reviewers for their comments. The data for this study were collected as part of the project AIR2-CT94-1066, sponsored by the European Commission.     

Economic inequality enhances inferences that the normative climate is individualistic and competitive

In addition to the negative effects of economic inequality on a range of health and social outcomes, we propose that inequality should also affect how people perceive the broader normative climate in society. We predicted that people living in a more unequal (vs. equal) society are more likely to appraise the social context as one where individualism determines people's behavior. We tested this idea in three experiments by manipulating the degree of economic inequality in a fictional society. We showed that, compared to the low-inequality condition, participants in the high-inequality condition were more likely to project individualistic norms onto society. Furthermore, Experiments 2 and 3 showed that in the high- (vs. low-) economic-inequality condition, participants inferred more competition and less cooperation between people. Our results are discussed in light of the importance of the perception of a broader normative climate to explain the consequences of economic inequality.     

Is There a Backlash Against Immigration From Richer Countries? International Hierarchy and the Limits of Group Threat

Why do immigrants from particular countries systematically face more opposition? To resolve inconsistencies of prevailing group‐threat theories, I reintroduce a long‐standing hypothesis stipulating that people have a disposition for maintaining status hierarchy between ethnic groups. Accordingly, independent of perceived economic or cultural threat, natives are more likely to prefer immigrant groups of higher status based on the development level of the group's national origin. To test this argument, I exploit a substantial provincial variation of immigration flows and attitudes in Spain—one of the only countries that has received immigrants from both less and more developed countries. Consistent with my hypothesis, I demonstrate that anti‐immigration attitudes are more widespread in areas with immigrants from less developed countries regardless of their economic and cultural characteristics. I further document that many voters perceive stable group hierarchies and that these preferences are more predictive of anti‐immigration attitudes in lower‐status immigration contexts. Overall, these results suggest that even culturally similar and economically beneficial immigrant groups from poorer countries can face public opposition due to their lower‐status national origin, highlighting the independent role of group‐status perceptions in politics.     

Devoutness to Islam and the Attitudinal Acceptance of Political Violence Among Young Muslims in Germany

This article investigates the links between religious beliefs and capitalist mentalities—namely devoutness to Islam and hierarchic self‐interest (HSI)—and violence‐accepting attitudes among the young Muslim migrant population in Germany. Following a situational perspective, these links are analyzed under different individual conditions structured by (socioeconomic) precariousness and education. Based on framing approaches and concepts from socialization theory, we derive the following hypothesis: The links between religious beliefs and capitalist mentalities and the attitudinal acceptance of violence are stronger among individuals with low levels of education and a precarious economic status (compared to high education/nonprecarious status). The strongest link is expected for a negative status inconsistency (high education/precarious economic status). Structural equation models for data from a random probability sample of 350 Muslims (aged 14–32 years) in Germany indicate that attitudinal acceptance of violence among young Muslims is not predicted by devoutness to Islam but by economic precariousness and by acceptance of capitalist values of the HSI belief system.     

社会经济不平等对个体生命史策略的影响——国家发展水平的调节作用

经济不平等不仅是经济问题,也会对个体心理行为产生诸多影响。前人认为,经济不平等会强化个体阶层提升意愿。结合生命史理论,研究提出高不平等将使个体偏好后代质量而非数量,以实现阶层提升,且这一现象在高发展水平国家中更为明显。基于开源数据,通过国家/个人两个水平上的分析发现,在高发展水平国家,经济不平等降低了国家生育率,并使个体更关切后代教育。研究结果可为理解特定经济环境下的个体心理和行为提供参考。     

Egalitarian nonconsequentialism and the levelling down objection

Telic egalitarianism is famously threatened by the levelling down objection. In its canonical form, the objection purports to show that it is not, in itself, an improvement if inequality is reduced. In a variant that is less often discussed, the objection is that telic egalitarians are committed to believing that sometimes one ought to reduce inequality, even when doing so makes no one better off. The standard egalitarian response to this ‘all things considered’ variant of the levelling down objection is to embed egalitarianism in a pluralist consequentialist moral theory. In section 1, I briefly recapitulate this familiar strategy. In section 2, I argue that this standard pluralist consequentialist response is inadequate. The inadequacy of the standard response, I argue, stems from the fact that the following are jointly inconsistent: (1) a commitment to levelling down's impermissibility; (2) standard pluralist egalitarian consequentialism; (3) inequality being of non‐trivial importance; and (4) the most plausible measures of inequality's badness. In section 3, I show that egalitarians can better respond to the all‐things‐considered levelling down objection by embedding egalitarianism in a nonconsequentialist moral theory.     

Vulnerable Women and Neo-Liberal Globalization: Debt Burdens Undermine Women's Health in the Global South

Contemporary processes of globalization havebeen accompanied by a serious deterioration inthe health of many women across the world. Particularly disturbing is the drastic declinein the health status of many women in theglobal South, as well as some women in theglobal North. This paper argues that thehealth vulnerability of women in the globalSouth is inseparable from their political andeconomic vulnerability. More specifically, itlinks the deteriorating health of many Southernwomen with the neo-liberal economic policiesthat characterize contemporary economicglobalization and argues that this structure issustained by the heavy burden of debtrepayments imposed on many Southern countries. In conclusion, it argues that many Southerndebt obligations are not morally bindingbecause they are not democraticallylegitimate.
