Insect succession and decomposition patterns on shaded and sunlit carrion in Saskatchewan in three different seasons

A study was conducted on decomposition and insect succession in the Prairie Ecozone of Saskatchewan in the year 2000. Eighteen domestic pig carcasses (42-79 kg) were employed as human models for applications to future homicide investigations in this region. Two major variables were considered including the effect of season and habitat (sun versus shade). Research was conducted over 25 weeks, spanning three seasons: spring, summer and fall. Ambient temperature, internal carcass temperature, faunistic succession over time, and the rate of decay were all compared for each experimental variable. Results indicated that habitat was only a factor in the decompositional rate of carrion in the spring season. The ambient temperature was the chief factor determining the seasonal variations in decay rate. Maximum internal carcass temperatures always coincided with the presence of 3rd instar larvae. Patterns of insect succession occurred in a predictable sequence that varied across different habitats and seasons and was unique compared to previously published studies. Carcasses placed in spring and fall attracted a more diverse assemblage of insects than summer-placed carrion. Sun-exposed carrion also had greater variation in fauna than shaded carrion in spring and fall. Members of Silphidae were the first coleopteran colonizers in all habitats and seasons. This paper also marks the first record for Cochliomyia macellaria (Fabricius) in Saskatchewan.     

Judicial use of social science research

American courts use social science research in three distinct ways: to make law, to determine facts, and to provide context. In this article, we review and critique the approaches that courts have traditionally taken to dealing with each form of social research. We also summarize and integrate a body of work offering a different perspective that treats law-making research associal authority, fact-finding research associal fact, and context-providing research associal framework. We end by proposing a coherent sequence of steps that courts should take when confronted with an empirical question about human behavior.This article was prepared under the auspices of the Task Force on Judicial and Regulatory Decisionmaking of the Carnegie Commission on Science, Technology, and Government. The views expressed are those of the authors rather than of the Task Force or the Commission. We are grateful to David Z. Beckler, Associate Director, for his comments.

Trends in City Conditions During the 1970s: A Survey of Demographic and Socioeconomic Changes

Changes in the demographic and socioeconomic conditions of 627cities between 1970 and 1980 are examined using simple comparisonof means and correlational analytic techniques. Cities are groupedaccording to their type (Central city; suburb), regional location,and rate of population growth (decline). Major changes occurredin employment patterns, income levels, economic bases, racialcomposition, and social pathologies (crime rates)—allmeasures of urban stress. These conditions tended to clusterin certain types of cities: large, declining central citiesof the Northeast and Midwest. But population decline and regionallocation were not found to be independent determinants of urbandistress. National and regional economic trends, especiallychanges in the vitality of the metropolitan area in which acity is located. were the primary determinants.     

Citizen-driven reform of local-level basic services: Community-Based Performance Monitoring

Amid growing interest in forms of participatory and decentralised governance, increasing efforts are being made to increase the accountability, responsiveness, and relevance of the state through active citizenship. Drawing on the theoretical basis for social accountability, this article explores bottom–up views of active citizenship which highlight the importance of the intrinsic as well as the instrumental value of participatory social accountability, and thus of active citizenship. One approach to social accountability, Community-Based Performance Monitoring (CBPM), is used to demonstrate these instrumental and intrinsic values in practice, in relation to local public-service delivery.     

Liability for sexual harassment in criminal justice agencies

This article focuses on sexual harassment in criminal justice agencies from a legal perspective. The article briefly describes sexual harassment cases that address agency liability decided by the United States Supreme Court, discussing the standards of liability articulated in Burlington Industries Inc. v. Ellerth (1998), Faragher v. City of Boca Raton (1998), and Meritor Savings Bank v. Vinson (1986). A more precise understanding of when agencies are liable for the actions of their subordinates is developed through an examination of lower federal court decisions. Trends in the law are identified, as case law is categorized according to harassment by supervisors and co-workers. The article concludes by exploring the policy implications flowing from court decisions and by calling for further research on this troubling aspect of the criminal justice workplace.
