There is no such thing there as a free gift.1Exchanges are peacefully resolved wars and wars are the result of unsuccessful transactions. 2As long as ceremonial exchanges continued to take place assurance, that peace prevailed, the linked groups could continue to carry on other mutually advantageous activities, such as trade in ordinary goods …3 相似文献

Multi-level research has shown that individual and community factors are important predictors of the risk for violent victimization. However, previous analyses have drawn different conclusions about the role of any given factor. These differences likely are related to variations in how violence is measured and to the fact that the data are drawn from different locales. The research presented here uses the 1995 National Crime Victimization Survey and tract-level census data to examine (1) how the risk of violence is distributed across persons and places in the United States and (2) whether empirical findings are sensitive to the operationalization of violence. Results show that some individual-level predictors (e.g., gender and race) are sensitive to the operationalization of violence, whereas others (e.g., age and marital status) are not. In addition, the impact of community characteristics on violence depends on central-city residence. In central cities, persons most at risk are in disadvantaged tracts, with lower proportions of immigrants. Outside central cities, the proportion of immigrants in an area increases risk, while community disadvantage has no independent influence. The importance of an empirical foundation for the development of theories of risk is discussed. 相似文献

This paper draws on a study of the introduction of market testing in the UK civil service to explore ways in which managers involved in the implementation of the new policy constructed evaluations of its impact. It is structured around three arguments. The first concerns the problems of evaluating 'what works' in the multi-stakeholder, multi-goal context of public management. The research highlights a range of overlapping and sometimes conflicting evaluation criteria across different organizational and occupational groupings. The second argument explores the difficulties of evaluation in the context of shifting policy objectives and the dynamic nature of institutional change. The research shows how the practitioners involved shaped and reshaped their construction of events over time as unanticipated benefits and disbenefits became evident. It also suggests ways in which they responded to the changing policy context, constructing new rules and norms of action over time. The third argument concerns the different levels of analysis underpinning managers' constructions of 'efficiency' and 'effectiveness', and how these constructions were deployed as strategies of legitimation in shaping the process of institutional change. 相似文献

This study examines type-specific and cumulative experiences of violence among a vulnerable population of youth. Sixty high-risk, shelter-dwelling, urban youth were interviewed regarding their history of childhood maltreatment, exposure to community violence (ECV), and experience with intimate partner violence (IPV). Results show a high prevalence and high degree of overlap among multiple types of violence exposure. Childhood physical, sexual (CSA), and emotional (CEA) abuse were interrelated and were associated with ECV. Cumulative experiences of childhood abuse (CCA) had a graded association with IPV victimization. In multivariate analyses, CCA and ECV were independently associated with IPV victimization. Gender moderated the effect of one association: CEA raised the risk of IPV victimization for girls but not for boys. Only CSA predicted IPV perpetration. Findings suggest that cumulative exposures to violence create cumulative risk for experiencing more violence. Shelter-dwelling, urban youth may be particularly vulnerable to this additive effect. 相似文献
