Injuries to law enforcement officers: the backface signature injury

In today's law enforcement community, one of the most vital tools an officer can possess is personal body armor. However, a recent Department of Justice investigation has raised important questions regarding the protection actually afforded officers through the use of personal body armor, and the current test methods used to assess the armor. Test results show that most Zylon-containing vests showed deformations in excess of the 0101.04 Standard's 44 mm backface signature limit. Such increased deformation can lead to serious injuries, including backface signature injuries, which have occurred in the field. Although the vest is successful in containing the round, it is not effectively dissipating the energy enough to prevent large amounts of vest deformation at the area of impact. Therefore, open, penetrating wounds occur even though the bullet did not penetrate the vest. The objective of the current study was to further define the backface signature injury through the use of case studies and laboratory experiments. Following the case study investigation, backface signature testing was conducted using a clay medium based on the NIJ 0101.04 Standard. The final component of this research involved the use of post-mortem human specimens (PMHS) for further investigation of the backface signature injury. Although the underlying cause of backface signature injuries is unknown, energy density is likely to play a role in the mechanism. Energy density (E/a) is defined as the energy per unit area and has been previously used in less lethal skin penetration research. Further research into the underlying causes of backface signature injuries is necessary. In addition to armor testing, the study of law enforcement personnel who have been shot while wearing soft body armor is also a valuable tool for determining the effectiveness of certification standards. Finally, it is important for medical personnel to recognize the backface signature injury and document this as a type of injury separate from blunt trauma or penetrating trauma behind armor injuries. Detailed knowledge of the injury, including the depth of the wound, would be beneficial to the scientific community.     

Toward an effective international legal order: from coexistence to concert?

In forbidding the use of force except in self‐defence against armed attack or when authorised by the Security Council, the UN Charter appears to be the culminating development of a system of international order based on the doctrine of state sovereignty. The cumulative result of international‐law‐related acts, omissions and declarations of the Bush administration since its inception can be construed as a fundamental challenge to the sovereign state system. The administration's stated security strategy is one possible response to undoubtedly grave challenges to national and human security. In fact, only an institutionalised partnership between the US and regional powers such as China, India, Brazil and Germany can hope to address those challenges successfully, in part because only it would have the requisite legitimacy. That partnership or concert could be organised within the UN framework, albeit intensifying its hierarchical elements.     

Voter turnout in presidential primaries: A cross-sectional examination

Decades of individual and aggregate level research suggest that three sets of factors influence voter turnout: the socioeconomic makeup of the potential voter; legal restrictions on voting; and the political context of each election. In this brief study, we use state-level data to test whether these factors combine to account for variations in turnout rates in the electoral arena of presidential primaries. As expected, high turnout is associated with states which have high median levels of education, lenient legal restrictions on voting, and a history of competitive two-party elections. Also congruent with our expectations, but at odds with research of other electoral arenas, high turnout in presidential primaries is unrelated to high campaign spending or close elections. We contend that spending in presidential primaries may be simply too low to stimulate turnout and that close primaries do not enhance turnout because voters are often unaware that the pending election will be close.The names of the authors appear in alphabetical order and imply that this study is in every way a collaborative enterprise.     

Civic Culture and Government Performance in the American States

In a recent study, Robert D. Putnam reported a strong relationshipbetween civic culture and government performance among the newlyempowered regions of Italy. This article extends Putnam's methodologythe American states. Using similar techniques, we constructindices of civic culture and government performance for thestates. When correlated, the results reveal a clear link betweencivicness and performance. States that are more civic lend tohave governments that enact more liberal and innovative policies.This relationship between civicness and performance remainsstrong even after controlling for political culture, ideology,education, and other factors.
