A method for identifying the group appurtenance of biological objects from subjects suffering from various diseases is developed. The method can be used in examination of putrefactive objects (blood, secretions, hair, etc.) and in cases when the group appurtenance cannot be identified by other methods.  相似文献

This investigation addressed the question of how two forms of social cognitive reasoning – epistemic reasoning and adolescent egocentrism – interface with externalizing and internalizing forms of psychopathology during adolescence. Adolescents’ epistemic reasoning (i.e., types of belief entitlement, or degree of doubt, held by an individual when confronted with contradictory sides of an issue), and imaginary audience and personal fable ideation, were assessed in a sample of 29 adolescent boys with behavioral problems and 30 of their peers without behavioral problems. To assess internalizing and externalizing symptomatology, teachers completed the Child Behavior Checklist (CBCL-TRF). Results revealed that, compared to those without behavior problems, boys with behavioral problems were lower in epistemic reasoning. Further analyses revealed consistent relations between dimensions of social cognitive reasoning to specific forms of psychopathology. These findings suggest that social cognitive reasoning, particularly epistemic doubt, is important in understanding problem behaviors among typical and atypical adolescents.

Analogizing the U.S. Department of Homeland Security to a corporate conglomerate consisting of multiple, formerly independent operating units with little in common and even less history of cooperation, this response to Professor Charles Wise prescribes the "bitter medicine" of interoperable communications. The critical function of assuring homeland security and disaster preparedness cannot depend on the uncertain trajectory of adaptive response.  相似文献

This article examines the policy consequences of the number of parties in government. We argue that parties externalize costs not borne by their support groups. Larger parties thus internalize more costs than small parties because they represent more groups. This argument implies that the public sector should be larger the more parties there are in the government coalition. We test this prediction using yearly time-series cross-sectional data from 1970 to 1998 in 17 European countries. We find that increasing the number of parties in government increases the fraction of GDP accounted for by government spending by close to half a percentage point, or more than one billion current dollars in the typical year. We find little support for the alternative claim that the number of legislative parties affects the size of the public sector, except via the number of parties in government .  相似文献

Abstract. Most decisions by the European Parliament are taken by an absolute majority of its members. Some decisions however – such as the approval of the budget of the European Union – require a two-thirds majority. The paper analyzes the a priori voting strength of the member states when their representatives vote coherently. It is shown that the increase in votes for Germany in the 1994 reallocation enhanced its position. A less favourable effect, however, can be seen for the other large members (France, Italy, the United Kingdom, and Spain). However, since votes in the EP tend to be cast according to partisan rather than national affiliation, the relative voting power of the political groups with respect to the two quotas is also analyzed. The tool to measure this is the (normalized) Banzhaf power index, partially extended to account for connected coalitions. The paper demonstrates that the distribution of votes between the present EU member states as allocated in proportion to their population size indeed roughly corresponds to their a priori voting power. However, the relative influence of the largest political groups, the European Socialists and the European People's Party, tends to be overestimated by their share of seats in the framework of the simple majority rule, but it is considerable if the quota is two-thirds. Finally, under the two-thirds majority rule, the European Liberal, Democratic and Reformist Party as well as the small groups appear to be almost powerless. The more the EP gains political leverage – a further increase in its institutional powers is to be expected in the framework of the ongoing Intergovernmental Conference – the more the distribution of voting power between the member states and between the political groups will be a crucial factor in the shaping of EU policies.  相似文献
