The population of 36 parents or parent figures arrested for killing their children or charges, who were under the age of 6 years in Detroit, Michigan, between 1982 and 1986, are described in the context of their deadly acts. This profile of parent-on-child homicide includes demographic and social characteristics of offenders and victims, circumstances of offense, andarrest and court dispositions.  相似文献

This article explores the congressional criminal justice policy-making process in the United States, using efforts toward federal criminal-code revision and capital punishment as case examples. It examines how interest groups and symbolic politics affect criminal justice policy and thereby attempts to enhance understanding of the political realities of criminal justice policy making. Based on the findings reported here, an approach to criminal justice policy making is recommended. This approach builds on the disjointed incremental model found in the political science literature and should facilitate criminal justice policy makers in becoming more effective participants in the legislative process.  相似文献

Work has not been extensively studied as a context for adolescent development, even though increased work experience has been widely recommended as a means of improving the transition of adolescents to adulthood. Studies of the impact of work experience on adolescent socialization, defined broadly, suggest that work has beneficial results that persist over time. Developmental theorists and critics of conventional patterns of workplace organization remind us, however, that current knowledge is inadequate to specify optimal types and amounts of work experience for adolescents. Studies of narrower outcomes of work experience — career knowledge and plans, job-related attitudes, behavior, and skills — are less persuasive. An ecological strategy is recommended for future research. Such research should consider the varying effects of different kinds of work experience on different adolescents and should seek those effects in settings other than the workplace and over long periods.Received his Ed.D. from the Harvard Graduate School of Education in 1975. Main interests are the transition of adolescents to adulthood and the development and evaluation of programs to ease that transition.Main interests are the interaction between families and human development, especially the effects of work.  相似文献

The microscopical examination of original surfaces on casework sized glass particles using an interference objective and the interpretation of their interferograms is discussed. To reduce subjectivity, a numerical criterion was devised to assess the curvature of glass particles and this was then applied to a survey of window, container, tableware and vehicle glasses. Objects with curved surfaces produced particles that were distinctly curved while those from surfaces of both modern and old windows were clearly identifiable as flat. Apparently flat surfaces from tableware and containers almost always yielded specimens that were detectably curved. In addition, there was no evidence that a fracture surface would be confused with an original surface from a plain flat glass.In a ‘blind’ trial to assess the interferometric routines, three examiners correctly identified flat and curved surfaces on 15 particles derived from a selection of glass objects.  相似文献

Long-range policy planning for international scientific and technological affairs has been hindered by a variety of problems. One is the overall crisis-response nature of foreign policymaking and another is the difficulty of developing technical information needed for sound forecasts. Within the State Department the record of attempts to establish systematic planning amply demonstrates the problems. Nevertheless, a number of key conclusions can be drawn from the few successful experiments in policy planning: An effective planning staff should combine the skills of both foreign policy specialists and scientists; planners should be closely familiar with, but not involved in, operations; the planning role requires consistent support from senior officials; the power to influence budgets significantly strengthens the planning function.  相似文献
