Abstract:
After a prolonged period during which studies of immigration and crime virtually disappeared from the literature, the topic has reemerged as a central theme of contemporary criminology. However, unlike the classic immigration studies that appeared in the first half of the twentieth century, most modern studies combine the various countries of origin into broad pan-ethnic groupings (such as Hispanic/Latino or Asian) that implicitly assume that criminological dynamics are relatively homogeneous within these aggregations despite the important social, cultural, and historical differences that are subsumed. This article utilizes data from the Children of Immigrants Longitudinal Study to illustrate the systematic within-category variation that such approaches can mask.

Abstract:
Objective: To empirically examine whether the educational background of child welfare workers in Florida impacts on performance evaluations of their work. Method: A proportionate, stratified random sample of supervisor and peer evaluations of child protective investigators and child protective service workers is conducted. ANOVA procedures are used to test if performance scores on a multitude of items differ for workers with university degrees in social work, psychology, sociology, criminology, education, business, and other fields. Results: The ratings of social workers’ skills and competency do not statistically differ from those workers with other educational backgrounds on 20 measures of performance. Conclusion: Findings suggest that the educational background of child welfare workers is a poor predictive variable of their performance as evaluated by supervisors and peers. However, more research is needed to determine if performance evaluations of workers are positively correlated with successful service outcomes with clients.
