The Spanish and Portuguese ISFG Working Group (GEP-ISFG) carried out a collaborative exercise in order to asses the performance of two Y chromosome STR tetraplexes, which include the loci DYS461, GATA C4, DYS437 and DYS438 (GEPY I), and DYS460, GATA A10, GATA H4 and DYS439 (GEPY II). The groups that reported correct results in all the systems were also asked to analyse a population sample in order to evaluate the informative content of these STRs in different populations. A total of 1020 males out of 13 population samples from Argentina, Brazil, Costa Rica, Macao, Mozambique, Portugal and Spain were analysed for all the loci included in the present study. Haplotype and allele frequencies of these eight Y-STRs were estimated in all samples. The lowest haplotype diversity was found in the Lara (Argentina) population (95.44%) and the highest (99.90%) in Macao (China). Pairwise haplotype analysis showed the relative homogeneity of the Iberian origin samples, in accordance with what was previously found in the European populations for other Y-STR haplotypes (http://www.ystr.org). As expected, the four non-Caucasian samples, Macao (Chinese), Mozambique (Africans), Costa Rica (Africans) and Argentina (Lara, Amerindians), show highly significant Phist values in the pairwise comparisons with all the Caucasian samples.  相似文献

According to a national survey, almost two out of every three Canadians think the federal government should be spending more to fight HIV/AIDS. The survey also found that: (a) although most Canadians know a lot about HIV/AIDS, there are some significant gaps in their knowledge; and (b) although most Canadians think HIV/AIDS is a serious problem, the vast majority do not consider themselves to be at risk for HIV infection. Few Canadians blame people for contracting HIV through sex or drug use, but many Canadians are still uncomfortable associating with people with HIV/AIDS in certain settings.  相似文献

国家自然科学基金资助项目形成的知识产权归属问题研究   总被引:2,自引:0,他引:2  
与私人投资相比 ,国家自然科学基金在资助的目的、资助的领域和投入的对象方面均有所差异。当前美国等发达国家和地区的立法对国家计划项目的成果归属所采取的放权原则值得我国借鉴。我国在确定国家自然科学基金资助项目形成的知识产权归属时应以适度放权为原则 ,以激励创新和促进利益平衡。  相似文献

This article investigates electoral participation and the antecedents of anti-integrationist voting (AIV) in the Danish 2004 European parliamentary elections. First, it focuses on the effects of the campaign and assesses the importance of social demographics and political predispositions vis-à-vis mediated and interpersonal communication on turnout. Second, it investigates AIV, focusing on 'hard' utilitarian predictors and 'soft' cultural predictors. It draws on the European Election Study (EES) post-electoral voter survey and a media content analysis of the most important news media outlets. Its findings corroborate previous research on political participation and shows significant positive effects of interpersonal political discussion and exposure to news media that portrayed the European elections as a conflict-laden contest on turnout. The analysis of AIV highlights the importance of proxies (lack of trust and dissatisfaction with the incumbent government) and political ideology, but also feelings of identity. The latter provides evidence from the Danish context in support of an emerging body of literature emphasizing 'soft' explanations of euroscepticism.  相似文献

Since the work of Downs (1957), spatial models of elections have been a mainstay of research in political science and public choice. Despite the plethora of theoretical and empirical research involving spatial models, researchers have not considered in great detail the complexity of the decision task that a candidate confronts. Two facets of a candidate’s decision process are investigated here, using a set of laboratory experiments where subjects face a fixed incumbent in a two-dimensional policy space. First, we analyze the effect that the complexity of the electoral landscape has on the ability of the subject to defeat the incumbent. Second, we analyze the impact that a subject’s “mental model” (which we infer from a pre-experiment questionnaire) has on her performance. The experimental results suggest that the complexity of a candidate’s decision task and her perception of the task may be important factors in electoral competition.  相似文献

The debate on the relationship between institutions and economic development is discussed, focusing on two illustrations, i.e., the impact of democracy and political instability on economic growth. Various pitfalls of existing research are identified, like sensitivity of the outcomes to model specification, sample heterogeneity, measurement of political variables, and the treatment of the time dimension.  相似文献

Observers say that drug production fuels violence in Colombia, but does coca production explain different levels of violence? This article examines the relationship between coca production and guerrilla violence by reviewing national‐level data over time and studying Colombia by department, exploring the interactions among guerrilla violence, exports, development, and displacement. It uses historical analysis, cartographic visualization, and analysis of the trends in four high coca‐producing and four violent Colombian departments, along with a department‐level fixed effects model. Contrary to the conventional wisdom, the department‐level analysis suggests that coca production is not the driving force of contemporary Colombian guerrilla violence. Instead, economic factors and coca eradication emerge as prominent explanatory factors.  相似文献

Much of the literature on the power of elected officials and bureaucratic agencies argues, from an empirical perspective, that bureaus appears to exercise autonomy. In this paper, a theoretical model sets out the conditions under which the Congress, the President, and one agency (we use the U.S. Federal Reserve as an extended example) can dictate policy outcomes. The results of the paper include the “Congressional Dominance” theorem: If more than 2/3 of House members, and more than 2/3 of Senate members, agree on something, they get it. The theorem is obvious (the “proof” is in the U.S. Constitution), but often forgotten in the substantive literature. More realistic results are derived for situations where the preferences of members of Congress are more diverse. Powers of the President to influence policy with, and without, appointments are also analyzed.  相似文献
