Federalism and the Safety Net: Delinkage and Participation Rates

Since the enactment of welfare reform legislation in 1996, thefederal government and the states have emphasized putting theneedy to work and reducing caseloads. Simultaneously, however,national policymakers delinked eligibility for cash assistancefrom eligibility for other safety-net benefits. Contrary tostated policy, though, this delinkage has led to declining participationin the case of Food Stamps and health-insurance programs forlow-income children. We highlight four factors that states mustshape if they are to narrow this gap between policy promiseand program performance by fostering higher participation. Weshow how our focus intersects with enduring questions of Americanfederalism—the level of state commitment to redistributiveprograms, their capacity to implement these programs effectively,and the degree to which states can augment governing capacityby becoming more genuine laboratories of democracy.     

A novel approach to the visualisation of heat-induced structural change in bone.

A new approach to visualising heat-induced change in bone was attempted. This was an attempt to counter the serious limitations of existing analytical methods yet still allow for the examination of subtle changes that occur due to burning. A new form of Magnetic Resonance Imaging was deemed to fulfil this remit. Preliminary tests were performed and proved successful in creating clear, well-defined images of progressive heat-induced structural changes in bone. The implications for improving our understanding of heat-induced change, and therefore our methods of human identification, are significant.     

The effects of death qualification on jurors' predisposition to convict and on the quality of deliberation

This study provides a straightforward test of the proposition that people who are permitted to serve on juries in capital cases (death-qualified jurors) are more likely to convict a defendant than are people who are excluded from serving on capital juries due to their unwillingness to impose the death penalty (excludable jurors). A sample of 288 subjects classified as death-qualified or excludable under theWitherspoon standard watched a 2 1/2-hour videotape of a simulated homicide trial including the judge's instructions, and gave an initial verdict. Death-qualified subjects were significantly more likely than excludable subjects to vote guilty, both on the initial ballot and after an hour's deliberation in 12-person juries. Nine juries were composed entirely of death-qualified subjects (death-qualified juries), while 10 contained from 2 to 4 excludable subjects (mixed juries). On postdeliberation measures, with initial death-penalty attitudes controlled, subjects who had served on the mixed juries were generally more critical of the witnesses, less satisfied with their juries, and better able to remember the evidence than subjects from the death-qualified juries, suggesting that diversity may improve the vigor, thoroughness, and accuracy of the jury's deliberations.     

Poverty elimination,North-South research collaboration,and the politics of participatory development

This paper reflects critically on issues of North-South collaboration and participatory research arising from a project on participatory and sustainable local-level environmental management in the peri-urban area surrounding Kumasi, Ghana. Rapid immigration, uncoordinated conversion of farmland to housing, intensified resource exploitation, and declining water quality and availability are particularly pressing problems there. Collaborative research arrangements with local partners as well as sustained participatory relations with selected village communities were central to this project. More generally, the paper reflects on institutional issues relating to the dichotomy between research and development assistance projects, and their implications for project evaluations.     

Estimation of age at death by tibial osteon remodeling in an autopsy series

Estimation of age at death by histological methods in tibiae has been found to be inaccurate in individuals less than 55 years of age. This study describes reasons for the inaccurate age estimates and provides a new regression equation for age estimation. Bone cores were removed from tibiae in 53 individuals at autopsy ranging in age from 17 years to 53 years of age; 48 males and 5 females. The sample contained 41 whites and 12 blacks. Variables ascertained from each core were: cortical thickness, cortical bone density, secondary osteon number, area, and perimeter, and Haversian canal area and perimeter. The results showed significant differences in secondary osteon number, area, and perimeter between groups aged less than and greater than 35 years of age. Multiple linear regression analysis indicated osteon number to be the best predictor of age in this sample aged less than 55 years of age. Age at death was accurately estimated for 11 additional forensic cases using osteon number in tibiae. No significant histological differences were observed between males and females and between blacks and caucasians.
