In paternity testing using the DNA evidence, analysis of the deficiency case when the DNA profiles of the alleged father are not available is different from that of the case with complete evidence. In this paper, we describe how to evaluate and determine the paternity in the deficiency case, by comparing the paternity indexes of the true father and the falsely non-excluded man.  相似文献

Traditional views hold that citizens' attitudes toward the police are driven by local concerns. We contend that public attitudes toward the police are responsive to systematic and periodic national-level political factors. In particular, we show that national elections as a focusing event alter periodically the determinants of attitudes toward the police. Using a logistic regression model and diachronic data from Costa Rica, Mexico, and the United States, we find that attitudes toward the police and the national government are linked, and this linkage is responsive to the influence of national election campaigns in varying degrees. In addition, we find that attitudes toward the Mexican police are sensitive to partisan changes in the composition of the national political government. We find no such sensitivity in the police attitudes of Costa Rican and U.S. citizens. This suggests that police attitudes are not only affected by the performance of the national political government but also by the character (consolidated versus unconsolidated) of the national political government. In short, police attitudes in new democracies are an indication of the unconsolidated nature of the state apparatus.  相似文献

元明清时期中国西南地区的交通发展   总被引:1,自引:0,他引:1  
元明清时期,中国西南地区主要存在6条对外通道,虽然各条道路的旅行时间在这一时期变化不大,但元明清政府所投入的巨大人力物力极大地改善了西南水陆交通状况,降低了交通运输成本,使西南地区的贸易量有了显著的增长.  相似文献

When you have a rational discussion of what to do with the Israeli settlements, how do you factor in the irrational, the deeply held beliefs of people with varying views? As we witnessed at the conference, when people speak about the Israeli settlements, they do so with emotion, using such phrases as “Messianic spirit,”“longing for homeland,”“compassionate revenge,” and “the destruction of dreams.” The land in question is precious to two different groups, who each imbue the land with their own narrative and fervor. In fact, at the very heart of what makes the settlements issue so complex and seemingly intractable is its psychological dimensions — the mental and emotional factors that permeate the discussion at every level.  相似文献

To evaluate whether the weight of the heart measured at autopsy may be affected by the type of dissection, a prospective study was undertaken of the weights of sequential cases of nonpediatric hearts. Four hundred fifty‐eight hearts were examined (age range 17–96 years; mean 55.9 years; M:F = 3:1). The hearts were each weighed fresh, once the apex had been sliced, the auricles of the atria opened and blood drained, and again once the cardiac chambers had been opened completely. The difference in the partially and fully opened heart weights (range 146–1028 g; mean 434.8 g; range 134–1011 g; mean 420.8 g, respectively) (p < 0.05) ranged from 0 to 100 g (mean 14 g). In the most extreme example, the weight of the partially opened heart was 30.3% higher than that of the fully opened specimen. Failure to fully open the heart prior to weighing may result in significant error.  相似文献

This paper analyses the particular challenges that tobacco control poses for health governance in an era of accelerating globalisation. Traditionally, health systems have been structured at the national level, and health regulation has focused on the needs of populations within individual countries. However, the increasingly global nature of the tobacco industry, and the risks it poses to public health, require a transnational approach to regulation. This has been the rationale behind negotiations for a Framework Convention on Tobacco Control (FCTC) by the Tobacco Free Initiative of the World Health Organisation (TFI/WHO). In recognition of the need to go beyond national governments, and to create a governance mechanism that can effectively address the transnational nature of the tobacco epidemic, WHO has sought to involve a broad range of interests in negotiations. The contributions of civil society groups in particular in the negotiation process have been unusual. This paper explores the nature and effectiveness of these contributions. It concludes with an assessment of whether the FCTC constitutes a significant shift towards a new form of global health governance, exploring the institutional tensions inherent in attempting to extend participation within a state-centric organisation.  相似文献

Over three phases of regulation, the paper traces a narrow range of regulatory interest in food, focusing largely on food safety and the handling of periodic food crises. We suggest that these crises were early indications of the problems in sustaining increasingly unsustainable modes of food production through global supply chains and that United Kingdom/EU regulation acted in part as a palliative, cloaking the wider systemic disorders. We go on to suggest that, as resource pressures become increasingly apparent in world food systems, a further fourth phase of food regulation will need to pay much greater attention to the resilience, sustainability, and security of food supply.  相似文献
