Using social network analysis (SNA), we propose a model for targeting criminal networks. The model we present here is a revised
version of our existing model (Schwartz and Rouselle in IALEIA Journal, 18(1):18–14, 2008), which itself builds on Steve Borgatti’s SNA-based key player approach. Whereas Borgatti’s approach focuses solely on actors’
network positions, our model also incorporates the relative strength or potency of actors, as well as the strength of the
relationships binding network actors.

This study examined the effects of variations in acculturation and gender on identity processes and outcomes. Three hundred fifty-seven students at a culturally diverse university completed measures of identity processes (exploration, commitment, and identity style) and outcomes (identity status). The generalizability of the underlying identity processes across contextual variations was ascertained by evaluating the consistency of factor solutions across immigrant generation and gender. Results suggested that the processes underlying identity development are consistent across variations in acculturation and gender. Supplemental analyses revealed effects of acculturation and gender on the extent to which individuals utilized various identity processes and manifested various identity outcomes. 相似文献

The authors were interested in discovering the spectrum and prevalence of sexual problems among young adults. With this goal in mind, they devised a Sexual Problems Check List as a comprehensive instrument utilizable by both clinicians and researchers. The Sexual Problems Check List was derived by reviewing therapists' treatment summaries and 146 recent answers to applications written by patients themselves as the first step in applying for treatment at a university mental health clinic. Data were then obtained from 52 subsequent student mental health clinic patients; such patients were selected as the sample because they were late adolescents and young adults thought likely to exhibit a broad range of clinically significant probelms. General patterns of concerns were noted which indicated that the sexual revolution has not been as liberating as the respondents were led to believe.Received his M.

Capillary electrophoresis is widely used in the forensic community for the analysis of Short Tandem Repeat DNA. The CE system used in most forensic laboratories allows the user to modify standard operational protocols to accommodate some samples that fall outside of interpretational guidelines. We have made operational changes and monitored system resolution and the ability of the software to identify alleles as a result of these modifications. Increased amount of amplified product in the injection preparation, lengthened injection times or repeated injections of the same sample were all investigated along with variations in run voltages. Certain protocol modifications offer some advantages to the analysis of STRs and may allow the analyst to avoid extraction of additional portions of crime scene samples to achieve interpretable results. 相似文献

Many studies suggest that personal ideology accounts for much more of congressional voting behavior than does attention to the desires of the electorate. There are two main explanations given for this seemingly robust conclusion: 1) poor measures of constituency preferences compared to those for ideology or behavior, and 2) representatives “shirk” on an inattentive electorate. We argue that existing studies have been biased against the “interest” explanation by ignoring the structure of American Congressional elections, in particular the party primary process. Correcting for the party primary effect, we show, within the context of abortion politics, that constituency interests possess greater explanatory power than previous models would suggest. 相似文献

It concludes by examining the prospectsfor successful implementation of the legislation and its likelyconsequences for the intergovernmental system. 相似文献

Like oysters on the half shell, some things are better when they're raw. In evaluating the performance of organizations and providing guidance for improving performance, however, raw performance measures, such as test scores or success rates, are often inferior to performance measures adjusted for client and environmental characteristics, or adjusted performance measures (APMs). Using examples from a variety of public services and data on public schools in Georgia, we compare the performance data generated by raw scores and by APMs. We conclude with guidance for constructing and using adjusted performance measures. 相似文献
