Skull identification by electronic photo-composition can, with the help of a video-animation compositor, be further developed beyond the pure superprojection technique into an animated picture difference image. The employment of this combined technique to be recommended on account of the improved possibilities of control to be realized in the congruity of the superprojection composite picture.  相似文献

The photographic identification of a skull through the well-known superprojection technique can be modified and decisively improved by the use of a video-tape system. The identification method based on electronic photo composition is methodically simple to use. It offers the examiner the possibility to recognize the relationship between bone and soft part proportions, and the structure of the bone surface and the details of the soft part shape, as a concrete, tangible characteristic of identity to a substantially greater extent. The large number of controllable characteristics inherent in the ihgh degree of individuality of the skull offers not just an either/or "The skull fits"/ "It does not fit" into a photograph, but achieves proof of disproof of identity.  相似文献

This article explains political radicalism by the number of voters who are biased towards a party. With little voters biased in favor of a party, this party has to rely more heavily on its programmatic distance to other parties. Because large parties – i.e.: parties with a high number of biased voters – gain votes when they move to the center of the political spectrum, parties with a lower number of voters that are biased in their favor are forced to the edges of the policy space. We draw on a computational model of political competition between four parties in a two‐dimensional policy space to investigate this relationship. We use panel corrected OLS estimates to analyze the data generated by the computer simulation. Our results substantiate the hypothesis of a negative relationship between the number of biased voters and the inclination of a party to adopt a more extreme policy stance.  相似文献

Most accounts of Swiss federal institutions are unable to explain institutional change. In this contribution the authors trace change in Cantonal reforms and then use multivariate explanation models to account for institutional reforms such as New Public Management reforms. The multivariate analyses used rely on an “event count model” to explain the frequency of institutional reforms and a “binary response model” to explain why Cantons adopt New Public Management reforms. This research demonstrates that policy research as well as innovation and diffusion theories can contribute to explaining institutional reform.  相似文献

The concept of responsibility lies at the heart of theories of democratic accountability. This article represents the first attempt to explicitly model attributions of presidential versus congressional responsibility for the economy. The article investigates the extent to which contextual and individual-level factors influence citizens' attributions of responsibility for the economy and how, in turn, such judgments shape their political evaluations. Employing a multinomial probit model of attributional choice, I find that responsibility judgments are shaped to varying degrees by economic ideology, perceptions of institutional context, and partisanship, although the effects of partisanship are not uniform across political parties. The results demonstrate that responsibility attributions are politically consequential and moderate the effects of economic perceptions on presidential and congressional approval. Finally, the results suggest that the effects of responsibility attributions in the sanctioning process are not invariant across the target of institutional evaluation .  相似文献

In the current debate on the future European order, the European Union (EU) is often described as an "emerging federation." This article claims that federalism is not exclusively useful in deliberating about the future of the EU. Non-statecentric conceptions of federalism provide a better understanding of the current structure and functioning of the European system of multilevel governance than most theories of European integration and international relations do. We combine political and economic perspectives of federalism to analyze the "balancing act" between effective political representation and efficient policy-making in the EU. Drawing on the examples of Germany and Switzerland in particular, we argue that the increasing delegation of powers to the central EU level needs to be paralleled by strengthened patterns of fiscal federalism and an empowered representation of functional interests at the European level. Without such "rebalancing," the current legitimacy problems of the EU are likely to intensify.  相似文献
