That adoption status, once begun, does not end for any adoptive family, and that agencies must be ready to help adoptive families whenever needed, has been generally agreed. For families that adopt special-needs children, the availability of help at all times is imperative and involves special considerations. This article sets forth the kinds of services that are needed, and describes a program particularly designed for this purpose. 相似文献

This article examines coverage of alcohol-related topics in local newspapers as applied to a conceptual model of media advocacy being tested in a five-component community trial to reduce alcohol-involved injuries. Based on a literature review of determinants of exposure of newspaper articles, it uses a composite measure that takes into account the likelihood that given articles will be read. This measure is evaluated in terms of the timing of media advocacy training, technical consultation, and resulting media advocacy efforts. Three hypotheses find support. First, postintervention levels of coverage across experimental communities appear generally higher than similar preintervention coverage. Second, although postintervention local and county coverage appears higher across experimental communities, no equivalent effect is present across comparison communities. Third, increases in local and county coverage in experimental communities were not matched by increases in state and national coverage in these communities. 相似文献

Hispanic Immigration and Black Violence at the Macro‐Level: Examining the Conditioning Effect of Victim Race/Ethnicity 下载免费PDF全文
Much attention has been devoted to the relationship between Hispanic immigration and violent offending at the macro‐level, including how it varies across racial and ethnic groups. Unfortunately, little attention has been paid to the conditioning effect of the race/ethnicity of the victim, or how Hispanic immigration is associated with crime by one racial/ethnic group against members of the same or different groups. Using National Incident‐Based Reporting System offending estimates and American Community Survey data, we examine the association between Hispanic immigration and black intra‐ and intergroup (black‐on‐white and black‐on‐Hispanic) homicide, robbery, and serious index violence in over 350 U.S. communities. We employ advanced imputation methods to address missing data that have constrained much prior research, as well as utilize crime measures adjusted for the likelihood of random contact between groups. Findings suggest that (1) Hispanic immigration has a positive association with black violence on the whole, but that (2) this association is conditioned by the race/ethnicity of the victim. Our results reinforce the importance of distinguishing across offender–victim dyads in research on the immigration–crime nexus, particularly in light of competing theoretical expectations. Directions for future research and policy are discussed. 相似文献

The problem of sequencing jobs on a machine in a job shop has been approached by a number of researchers and practitioners. One of the most popular methods is to apply a priority rule to the queue at each machine. The authors have previously published details of an approach which sets the priority of a job as a linear combination of the operation times and due date for that job. The coefficients in the linear combination are set by a simulation and search procedure so as to give good performance based on the performance measure specified. This paper extends this approach to include setup time factors. This extended approach is then applied to data from an actual manufacturing system. The extended approach is shown to improve the performance of the manufacturing system in relation to existing techniques. 相似文献
