In accordance with Puppe's rule, the analysis of skull fractures may provide evidence on the sequence in which multiple blunt injuries of the skull occurred. In cases of multiple gunshot wounds of the skull determination of the sequence in which the gunshot wounds took place is much more difficult. In some cases, however, analysis of the skull fractures here can also allow the order in which gunshot wounds occurred to be established. 相似文献
This article describes the difficulties of reducing analysis of energy use to an application of economic theory. It shows how economic concepts of behavior direct attention selectively to some important determinants of consumer behavior and away from others; how available economic accounts of short-term change in energy use, investment in energy efficiency, and the dynamics of investment limit understanding and narrow analysts' vision; how promising policy options are overlooked as a result; and how concepts and knowledge from the noneconomic behavioral sciences can compensate. Two strategies are discussed for improving analysis. Using economic theory to guide the improvement of existing models can help, conceptual blind spots will remain. A problem-oriented approach drawing on concepts and methods from across the behavioral sciences can avoid the blind spots, but cannot be systematic. Analysis can be improved by using both approaches in concert; some implications of a combined strategy are sketched. 相似文献
State spaceports are an interesting example of intergovernmentalrelations because activities conducted at such facilities spanthe state, federal, and international realms. Five statesAlaska,California, Florida, New Mexico, and Virginiaare themost visible participants in the process. In this study, thesupporting rationales for such endeavors are discussed withinthe context of the broader contours of intergovernmental relations.The field is a product of the post-Cold War period during whichopportunities for state space activities arose due to changesin the national security environment. Three distinct but interrelatedexplanations are suggested for why the field has developed slowly,although during the past two years, progress in achieving goalshas begun to occur. 相似文献
Correctional facilities have a discernible social climate, or collection of contextual properties that derive in part from the perceptions of inmates. These properties include the physical, organizational, social, and emotional characteristics of correctional institutions. Social climate directly influences the attitudes and behavior of inmates, their well-being, and prison management. The present study describes the results of an applied research project conducted in association with a government agency that audits Ohio’s prisons and youth facilities through site inspection visits and survey data. The agency’s questionnaires, as well as the procedures used to sample inmates and administer the instruments, were evaluated to determine the degree to which they accurately reflected the perceptions of inmates and the social climate of the correctional institutions. We identified several problems related to survey construction and administration. The results suggest that the surveys are at least to some degree not measuring several important dimensions of the correctional environment and the experiences of inmates as intended.
Among families in the child welfare system, family reunification depends largely upon the services to which families are referred. This study examines whether race/ethnicity influences the number and types of services to which families are referred. Findings suggest that compared to African American families, Hispanic families were more often referred to psychosocial services (e.g., mental health) than basic needs (e.g., housing). These findings indicate a need to reduce service referral disparities between ethnic groups. 相似文献
When do government policies induce responsive political participation? This study tests two hypotheses in the context of military draft policies. First, policy‐induced risk motivates political participation. Second, contextual‐level moderators, such as local events that make risk particularly salient, may intensify the effect of risk on participation. I use the random assignment of induction priority in the Vietnam draft lotteries to measure the effect of a son's draft risk on the voter turnout of his parents in the 1972 presidential election. I find higher rates of turnout among parents of men with “losing” draft lottery numbers. Among parents from towns with at least one prior war casualty, I find a 7 to 9 percentage point effect of a son's draft risk on his parents’ turnout. The local casualty contextual‐level moderator is theorized to operate through the mechanism of an availability heuristic, whereby parents from towns with casualties could more readily imagine the adverse consequences of draft risk. 相似文献
Existing research highlights that families face geographic, social, and psychological constraints that may limit the extent to which competition can take hold in school choice programs. In this paper, we address the implications of such findings by creating a network of student flows from 11 cohorts of eighth‐grade students in the Chicago Public Schools (CPS). We applied a custom algorithm to group together schools with similar sending and receiving patterns, and calculated the difference in mean achievement between a student's attended and assigned high schools. For all identified school groupings, we found that the students were on average moving to higher achieving schools. We also found that the movement toward higher achieving schools of the top achievement quartile of students was over twice as large as that of the bottom quartile, but that the flows of both the highest and lowest achieving student quartiles were toward higher achieving destinations. Our results suggest that student movements in CPS between the years of 2001 to 2005 were consistent with creating market pressure for improvement as well as increasing segregation by achievement. However, further research into how schools responded to those movements is required to make inferences about the level or consequences of competition generated by choice‐related reforms during that time. 相似文献
