According to Philippe Rushton, the equalitarian fiction, a scientific hoax that races are genetically equal in cognitive ability, underlies the politically correct objections to his research on racial differences. He maintains that there is a taboo against race unequaled by the Inquisition. I show that while Rushton has been publicly harassed, he has had continuous opportunities to present his findings in diverse, widely available, respectable journals, and no general suppression within academic psychology is evident. Similarly, Henry Garrett and his associates in the LAAEE, dedicated to preserving segregation and preventing race suicide, disseminated their ideas widely, although Garrett complained of the equalitarian fiction in 1961. Examination of the intertwined history ofMankind Quarterly, German Rassenhygiene, far right politics, and the work of Roger Pearson suggests that some cries of political correctness must be viewed with great caution.Preparation of this paper was not supported by any grant, foundation, political, or religious organization.specializing in the history of psychology and psychological aesthetics.  相似文献

This paper examines the processes of organizational adaptation and competitiveness of firms in an emerging economy. The study is set in the Argentinian context of the 1990s when a combination of economic and political change triggered a massive change in the competitive context of indigenous firms. Two highly flexible firms and two less‐flexible firms are studied from the pharmaceutical and edible oil industries and longitudinal data are supplied to explore the determinants of organizational flexibility in those organizations.  相似文献

This paper is an assessment of the impact of child support enforcement and welfare policies on nonmarital teenage childbearing and motherhood. We derive four hypotheses about the effects of policies on nonmarital teenage childbearing and motherhood. We propose that teenage motherhood and school enrollment are joint decisions for teenage girls. Based on individual trajectories during ages 12–19, our analysis uses an event history model for nonmarital teenage childbearing and a dynamic model of motherhood that is jointly determined with school enrollment. We find some evidence that child support policies indirectly reduce teen motherhood by increasing the probability of school enrollment, which, in turn, reduces the probability of teen motherhood. This finding suggests that welfare offices may wish to place greater weight on outreach programs that inform more teenagers of the existence of strong child support enforcement measures. Such programs might reduce nonmarital teen motherhood further and thus reduce the need for welfare support and child support enforcement in the long run.

In the presence of rare disasters, risk perceptions may not always align with actual risks. These perceptions can nevertheless influence an individual's willingness to mitigate risks through activities such as purchasing flood insurance. In a survey of Maryland floodplain residents, we find that stated risk perceptions predict voluntary flood insurance take‐up, while perceptions themselves varied widely among surveyed residents, owing in large part to differences in past flood experience. We use a formal test for overoptimism in risk perceptions and find that, on aggregate, floodplain residents are overly optimistic about flood risks.  相似文献

Abstract

Grubbs and Weaver (1947 Grubbs, F. E., and C. L. Weaver. 1947. The best unbiased estimate of population standard deviation based on group ranges. Journal of the American Statistical Association 42 (238):22441. doi: 10.2307/2280652.[Taylor & Francis Online], [Web of Science ®] [Google Scholar]) suggest a minimum-variance unbiased estimator for the population standard deviation of a normal random variable, where a random sample is drawn and a weighted sum of the ranges of subsamples is calculated. The optimal choice involves using as many subsamples of size eight as possible. They verified their results numerically for samples of size up to 100, and conjectured that their “rule of eights” is valid for all sample sizes. Here we examine the analogous problem where the underlying distribution is exponential and find that a “rule of fours” yields optimality and prove the result rigorously.  相似文献

Although psychological approaches have been the mainstay of scholarly research on school climate, offering state-of-the-art measurements and methodologies, sociological perspectives remain essential perspectives because violence is essentially a social phenomenon. This paper offers a theoretical consideration of contributions to this field, focusing specifically on those that provide a critical historical lens. I suggest that while Foucault's approach to the disciplining of docile bodies and self-restraint offers crucial conceptual tools, Norbert Elias's work—which is scarce in scholarly research on school climate—provides a complementary but necessary framework for understanding emotional and relational aspects of peer harassment.  相似文献

There is mixed evidence in the existing literature on whether children are associated with greater subjective well-being, with the correlation depending on which countries and populations are considered. We here provide a systematic analysis of this question based on three different datasets: two cross-national and one national panel. We show that the association between children and subjective well-being is positive only in developed countries, and for those who become parents after the age of 30 and who have higher income. We also provide evidence of a positive selection into parenthood, whereby happier individuals are more likely to have children.  相似文献

ABSTRACT

This article analyses European integration's effects on migration and border security governance in Slovenia, Croatia and Macedonia in the context of ‘governed interdependence’. We show how transgovernmental networks comprising national and EU actors, plus a range of other participants, blur the distinction between the domestic and international to enable interactions between domestic and international policy elites that transmit EU priorities into national policy. Governments are shown to be ‘willing pupils’ and ‘policy takers’, adapting to EU policy as a pre-condition for membership. This strengthened rather than weakened central state actors, particularly interior ministries. Thus, in a quintessentially ‘national’ policy area, there has been a re-scaling and re-constitution of migration and border security policy. To support this analysis, social network analysis is used to outline the composition of governance networks and analyse interactions and power relations therein.  相似文献

We develop a parsimonious model to study the equilibrium and socially optimal decisions of banks to enter, trade in, and possibly exit, an OTC market. Although we endow all banks with the same trading technology, banks' optimal entry and trading decisions endogenously lead to a realistic market structure composed of dealers and customers with distinct trading patterns. We decompose banks' entry incentives into incentives to hedge risk and incentives to make intermediation profits. We show that dealer banks enter more than is socially optimal. In the face of large negative shocks, they may also exit more than is socially optimal when markets are not perfectly resilient.  相似文献
