This article examines the state of intensive family preservation services (IFPS) research. Using studies of IFPS in five states, this article seeks to establish whether IFPS can be regarded as an evidence-based practice, an increasingly important standard for publicly funded services. While reporting rates of repeat child maltreatment, the analysis uses placement rates as the main outcome measure and compares effect sizes using Cohen's arcsine transformation for data reported as proportions. Significant differences in rates of child out-of-home placement and repeat maltreatment were found in some studies, particularly for higher risk families. The findings also underscore the difficulty of identifying which families to serve (targeting), ensuring treatment fidelity, and employing rigorous and appropriate evaluation methods. Overall, additional research is needed to move IFPS from a promising practice to an evidence-based practice.  相似文献

This paper models the increase in the participation rate of criminal behavior as either the initiation rate or the career length of criminals changes in response to increases in unemployment. Even with large instantaneous increases in unemployment, the models show a very slow increase in the criminal participation rate, giving a possible explanation of the failure of many studies to demonstrate a link between unemployment and crime levels.  相似文献

We have analyzed variation of the mitochondrial DNA (mtDNA) hypervariable segments I and II (HVS-I and HVS-II) in 185 randomly chosen individuals from Korea to provide an expanded and reliable Korean database. Combined sequence comparison of HVS-I and HVS-II led to the identification of 167 different haplotypes characterized by 154 variable sites. One hundred and fifty-one of the haplotypes were individual-specific, 14 were found in two individuals and 2 were found in three individuals. A pairwise comparison of the 185 HVS-I/II sequences found an average of 10.11 +/- 4.63 differences between individuals. The random match probability and gene diversity for the combined hypervariable regions were estimated at 0.66% and 0.9988, respectively. Analyzing the expanded database including three previously reported data sets and the present data using haplogroup-based comparisons and comparison with closely related sequences allowed errors to be detected and eliminated, thus considerably improving data quality. Sample division comparisons based on PhiST genetic distance measures revealed no significant population differentiation in the distribution of mtDNA sequence variations between the present data set and a database in The Scientific Working Group on DNA Analysis Methods (SWGDAM), but did indicate differences from other sets of data. Based on the results of mtDNA profiles, almost all of the mtDNA types studied here could be classified into subsets of haplogroups common in east Asia, and show that the Koreans possess lineages from both the southern and the northern haplogroup complexes of east Asian populations. The new data, combined with other mtDNA sequences, demonstrate how useful comparison with closely related mtDNA sequences can be for improving database quality, as well as providing haplotype information for forensic and population genetic analyses in the Korean population.  相似文献

The current research produces regression models with sample sizes from 127 to 131 by initially employing a data set of 170 nations. The current study finds that ethnic heterogeneity and linguistic heterogeneity lead to higher homicide rates. However, religious heterogeneity has no impact on homicide rates. The present article also tests an interaction effect between population heterogeneity and income inequality. Unlike J. R. Blau and Blau (1982) and Avision and Loring (1986) proposition, the interaction term is not related to national homicide rates. The current study also discusses the theoretical implications of those findings.  相似文献

This article analyzes China’s coherence in international economic governance. When and how is China challenging the rules and norms of the prevailing international economic order? Has China adopted the current rules and norms across the board, or is it proceeding in an ad hoc or piecemeal manner? How can its (in) coherence be explained? To address these questions, I compare China’s profile vis-à-vis three dimensions of the global economic order: trade, investment, and development aid. I argue that in international trade and investment, China has neither sought nor brought about significant change. China is however, offering an alternative to the Western norms that until now have dominated the global development aid regime. China’s establishment of the Asian Infrastructure Investment Bank (AIIB) is notable in this regard, though it is still soon to determine if the Chinese-led development bank will break with existing norms. The article then considers possible theoretical explanations for the variation in China’s behavior across the three areas.  相似文献

Professors Schauer and McAdams both seek a more or less sweepingly general theory of why we obey the law. But we should split, not lump. There are different reasons different actors in different social settings obey different laws–not only, but not least, out of regard for democratic decision making.  相似文献
