A report of an international collaborative experiment to demonstrate the uniformity obtainable using DNA profiling techniques. 总被引:2,自引:0,他引:2

This paper describes a collaborative exercise intended to demonstrate whether uniformity of DNA profile results could be achieved between different European laboratories. It was shown that this goal can be obtained provided that a common protocol is followed (specifically the use of a common electrophoretic buffer as being the most important parameter). Generally, lower molecular weight loci (with lower molecular weight fragments) such as YNH24 perform better than higher molecular weight loci such as MS43a. The results of the exercise are discussed in relation to the objectives of the European DNA profiling group (EDNAP). 相似文献

The growing literature about mixed electoral systems has addressed their effect on party systems, voting behavior, campaign strategies, legislative roll-call voting, and other issues in a handful of countries. But, the effect of mixed systems has not been fully evaluated cross-nationally or longitudinally. Using data from the World Bank’s Database of Political Institutions, we address this gap in the literature by investigating two related questions. First, do mixed electoral rules produce different election outcomes than other election rules? Second, are these results attenuated by the definitions of mixed systems that scholars employ? We find that mixed systems generate outcomes that are distinct from other electoral systems and that these findings are generally robust across different definitions. 相似文献

The modern history of divided government in America suggests that the framers succeeded in creating a government unresponsive to popular passions. Yet in the nineteenth century the party winning the presidency almost always captured control of the House of Representatives. Why and how could nineteenth century national elections be so responsive that they resemble parliamentary outcomes? We identify electoral institutions present in the states that directly linked congressional elections to presidential coattails. Specifically, we estimate the impact of state ballot laws and the strategic design of congressional districts on presidential coattail voting from 1840 to 1940. We find that presidential elections, as mediated by state electoral laws, strongly account for unified party control of the House and the presidency throughout the nineteenth century. 相似文献

Erik Gartzke 《国际研究季刊》2000,44(2):191-212
A debate exists over whether (and to what degree) the democratic peace is explained by joint democracy or by a lack of motives for conflict between states that happen to be democratic. Gartzke (1998) applies expected utility theory to the democratic peace and shows that an index of states' preference similarity based on United Nations General Assembly roll-call votes ( affinity ) accounts for much of the lack of militarized interstate disputes (MIDs) between democracies. Oneal and Russett (1997b, 1998, 1999) respond by arguing that UN voting is itself a function of regime type—that democracy 'causes' affinity . Oneal and Russett seek to demonstrate their thesis by regressing affinity on democracy and other variables from a standard model of the democratic peace. I replicate results reported by Oneal and Russett and then extend the analysis in several ways. I find that the residuals from Oneal and Russett's regression of affinity remain highly significant as a predictor of the absence of MIDs. Further, significance for democracy is shown to be fragile and subject to variable construction, model specification, and the choice of estimation procedure. 相似文献

This paper aims to redress the under-appreciated significance of rent for political ecological analysis. We introduce the notion of value grabbing, defined as the appropriation of (surplus) value through rent. A concept that is analytically distinct from accumulation, rent is both a social relation and a distributional process that is increasingly central to the reproduction of contemporary capitalism. Emphasis is placed on the “grabbing” of value in order to shed light on the processes at work by which surplus value is distributed unevenly between different classes and fractions of classes. A focus on rent within political ecology, we argue, can help us distinguish between two organically related but analytically distinct “moments”: (a) the creation of property rights that establish rent relations and (b) the struggle over the appropriation and distribution of surplus value generated by the rent relation itself. We explore some of the implications of this perspective for understanding new forms of socio-ecological struggles and their varied relations to the state. We maintain that a value-grabbing perspective has far-reaching consequences for political ecology, as it provides a sharp conceptual tool for situating a wide range of socio-ecological conflicts and movements as class struggles over value appropriation and distribution. 相似文献
