Validation of chest X-ray comparisons for unknown decedent identification

Comparing skeletal structures between antemortem and postmortem chest radiographs is widely used by forensic specialists from many disciplines to positively identify unknown decedents. However, validity assessments of this method have been fairly limited. This study had three objectives: 1) to quantify the reliability of ante- and postmortem chest radiograph comparison for decedent identification; 2) to identify useful radiologic features supporting decedent identification; and 3) to recognize sources of error in decedent identification related to use of comparative radiographs. A forensic pathologist, a forensic anthropologist, and two radiologists participated in the study. Our results showed that chest radiograph comparisons proved reliable, if basic decedent information was provided, and antemortem and postmortem radiographs were adequately positioned and exposed. A "morphological approach" using normal anatomical structures for comparison may provide the most efficient method for accurate identification.     

Recent developments in medicine and law

A method for group identification of hair infected with Microsporum

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.     

Collaboration over Adaptation: The Case for Interoperable Communications in Homeland Security

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.     

Voting strength in the European Parliament: The influence of national and of partisan actors

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.
