Abstract. Genetic Similarity Theory extends Anthony D. Smith's theory of ethno‐symbolism by anchoring ethnic nepotism in the evolutionary psychology of altruism. Altruism toward kin and similar others evolved in order to help replicate shared genes. Since ethnic groups are repositories of shared genes, xenophobia is the ‘dark side’ of human altruism. A review of the literature demonstrates the pull of genetic similarity in dyads such as marriage partners and friendships, and even large groups, both national and international. The evidence that genes incline people to prefer others who are genetically similar to themselves comes from studies of social assortment, differential heritabilities, the comparison of identical and fraternal twins, blood tests, and family bereavements. DNA sequencing studies confirm some origin myths and disconfirm others; they also show that in comparison to the total genetic variance around the world, random co‐ethnics are related to each other on the order of first cousins.  相似文献

In this paper we examine some of the major planning challenges facing the Paris region and we locate these in the context of problems of institutional coordination and cooperation. Finding the right institutions for metropolitan governance is a challenge for most of Europe's large cities. Our approach to the Paris region emphasizes the need to understand the evolution of institutions of governance and the struggles between political actors around these institutional legacies. Political competition motivates key actors in the multi-level governance of the region. We examine the struggle to develop new social housing and conflicts around transport policy in Paris. Political conflict and different perspectives on regional planning stand in the way of solutions to current problems. In the final part of the paper we discuss how potential political and institutional solutions might develop.  相似文献

有关西方旅游者在华旅游活动的现有研究缺乏系统性,且几乎都借助于中国官方机构的统计信息。由于统计方法存在明显的缺陷,这些统计信息往往无法有效地反映旅游者的实际活动轨迹和活动内容。本文以西方旅游批发商的产品样册为基础,运用自创的分析方法研究西方旅游者的在华旅游活动。研究表明,西方旅游者主要是受中华文明吸引而来华旅游,西方各国旅游批发商推出的中国游产品没有明显的差异性。  相似文献

This article focuses on the various actors in the urban setting who contribute to the increase in the forced mobility of homeless injection drug users and crack smokers in Montréal, Canada. The objective is to analyze who these actors are and how they contribute to increasing this forced mobility from the perspective of homeless injection drug users and crack smokers in relation to three needs : basic needs, acquisition of financial resources, and drug use. One hundred and six semi-structured interviews were conducted among this population. The results indicate that various actors—police officers, community organization, peers, municipal administration, storekeepers, and residents—contribute to the forced mobility of this population in their daily activities. As for their needs, it is when they use drugs, sleep, or loiter that they are more likely to experience events of forced mobility. Police officers are by far the actors who contribute the most to this, often in a repressive way. The role of the municipality is also a determining factor in the daily activities of homeless injection drug users and crack smokers.  相似文献
