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

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

High public interest today in political communications such as ‘spin’ and in political participation such as electoral turnout suggests that there may be value in exploring the processes by which political messages are produced and consumed, and their inter‐relationship with participation. It may be that what citizen‐voters think of message production influences how they consume political news and publicity (through observing and evaluating), and that the propensity to political participation is subsequently affected. This paper offers a model which traces the production of political communications, starting at their origins in the political class, and flowing via traditional political journalism or controlled media and new media to citizen‐voters who both observe and evaluate them (ie consume them) before, during and after making any political choices. It is hypothesised that the observation and evaluation of message production and content by political consumers influences both their types and levels of participation. Research of this nature into political organisations is relatively rare. Similarly, there is little evidence of investigations into other aspects highlighted in the model: attitudes of the political class towards political communications, the production of political communications before they reach the media and how they are received by the media, and their consumption by citizen‐voters in relation to the propensity to participate in politics.

If manufacturing a safer cigarette is technically possible--an open question--then mandating that tobacco manufacturers improve the safety of cigarettes would likely have both positive and negative implications for the nation's health. On the one hand, removing toxins may reduce the incidence of smoking-related diseases and premature mortality in smokers. On the other hand, smokers might be less inclined to quit, those who have quit might resume the habit, and youth who have never smoked will have one less reason to avoid tobacco use. To assess the expected population health impacts of a legislative or regulatory mandate, we created the Tobacco Policy Model, a system dynamics computer simulation model. The model relies on secondary data and simulates the U.S. population over time spans as long as 50 years. Our simulation results reveal that even if requiring cigarettes to be safer makes smoking more attractive and increases tobacco use, a net gain in population health is still possible. 相似文献

Bonding in parent, peer, and school domains were compared in a general sample of children and a sample of children of methadone-treated parents. Bivariate comparisons revealed that children of methadone-treated parents had lower SES, and were significantly more likely to smoke cigarettes but not more likely to drink alcohol. Several measures of attachment were significantly different between the two samples across parent, peer, and school domains. Multivariate analyses indicated that the children of methadone-treated parents were more likely to smoke, even after accounting for the effects of demographic and attachment variables. For drinking, sample membership was not found to be significant. Attachment to school decreased the odds of both smoking and drinking in both samples. Peer attachment had no effect on the odds of smoking initiation; however,loyalty to best friend did predict increased odds of drinking initiation. 相似文献

This article examines the effect of primary season presidential debates on voters' attitudes toward presidential candidates. Employing a pretest-posttest quasi-experimental design, we examine the 1996 Arizona Republican primary debate. We find that the debate led respondents to change their viability and electability assessments of the candidates and produced significant changes in respondents' vote preferences. In addition, we demonstrate that changes in viability, changes in electability, as well as differences between expected and actual debate performance influenced the vote preferences of audience members. We conclude by speculating about the debate's effect on the Arizona Republican primary, and by noting the potentially important differences between the impact of general election and primary debates. 相似文献

Multiparty electoral competition in the Netherlands and Germany: A model based on multinomial probit
Schofield Normal Martin Andrew D. Quinn Kevin M. Whitford Andrew B. 《Public Choice》1998,97(3):257-293
A typical assumption of electoral models of party competition is that parties adopt policy positions so as to maximize expected vote share. Here we use Euro-barometer survey data and European elite-study data from 1979 for the Netherlands and Germany to construct a stochastic model of voter response, based on multinomial probit estimation. For each of these countries, we estimate a pure spatial electoral voting model and a joint spatial model. The latter model also includes individual voter and demographic characteristics. The pure spatial models for the two countries quite accurately described the electoral response as a stochastic function of party positions. We use these models to perform a thought experiment so as to estimate the expected vote maximizing party positions. We go on to propose a model of internal party decision-making based both on pre-election electoral estimation and post-election coalition bargaining. This model suggests why the various parties in the period in question did not adopt vote maximizing positions. We argue that maximizing expected vote will not, in general, be a rational party strategy in multiparty political systems which are based on proportional representation. 相似文献
