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

Modernisierung und Konvergenz ihrer Mitgliedsländer ist das sozio?konomische Zwillingsziel der Europäischen Union. Doch inwieweit kann die EU diese Prozesse überhaupt steuern? Dies wird in diesem Artikel für den Zeitraum 1970 bis 2000 empirisch untersucht und mit der Frage nach Mechanismen und Grenzen einer EU-induzierten Angleichung verbunden. Die EU-Gesellschaften sind durch einen Großtrend der Modernisierung aller Mitgliedsländer und einen Subtrend der nachholenden Modernisierung der leistungsschwächeren Länder gekennzeichnet. Es überwiegt die Konvergenz, bei vereinzelten Divergenzen und ?neuen Unterschieden“ im Zuge neuartiger Anpassungsprobleme. In weiten Teilen folgen Modernisierung und Konvergenz einer eigenen, integrationsunabhängigen Logik, doch werden beide durch die europäische Integration unterstützt. Die EU-Mitgliedschaft wirkt über die Mechanismen Ressourcendistribution, Konkurrenz, Regulation und Imitation vor allem für die Nachzügler modernisierungsfördernd und verstärkt dadurch die Konvergenz. Zugleich gibt es Grenzen einer EU-induzierten Angleichung. 相似文献

This article analyzes the relationship between the different forms of direct democratic participation and the size of the tax state in the Swiss cantons for the period from 1983 to 2000. The analysis distinguishes between the different effects of the financial referendum and the initiative. Theoretical arguments suppose that the financial referendum curb the tax state, whereas the initiative is expected to contribute to its growth. Pooled time series analyses show that legal conditions of direct democratic participation in general and especially the legislation on financial referenda are much more important than the frequency of plebiscites for the explanation of the different sizes of the tax states in the cantons. As an additional result of the analyses, the impact of direct democracy on the tax state turns out to be much larger in the 1990s compared to the decade before. 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

Based on an experimental study about the televised debates in the last German federal election campaign, the article analyses how the candidates — Schröder and Stoiber — were perceived by the audience. Based on real-time-response-data, the crucial role that already existing attitudes play in the process of debate perception is shown. Still, debates do have effects, although these vary among voters depending on their specific situations. Debates have a mobilizing effect on partisans, while there is a potential persuasive effect on independent voters. 相似文献

During the last few decades, both policy practices and policy idioms have drastically changed. Concepts such as interactive
planning, network management, stakeholder dialogue, deliberative democracy, policy discourses, governance, etc. have replaced
older ones such as public administration, policy programmes, interest groups, institutions, power, and the like. Although
we recognise the relevance and importance of this shift in vocabulary, we also regret related ‘losses’. We particularly regret
that the concept of power has – in our view – become an ‘endangered species’ in the field of public policy analysis. We therefore
will develop a framework to analyse power – being a multi-layered concept – in policy practices in this article. We will do
so on the basis of the so-called policy arrangement approach, which combines elements of the old and new policy vocabularies.
In addition, we draw upon different power theories in developing our argument and model. As a result, we hope to combine the
best of two worlds, of the ‘old’ and the ‘new’ idioms in policy studies, and to achieve our two aims: to bring back in the
concept of power in current policy analysis and to expand the policy arrangement approach from a power perspective. 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
