Using longitudinal archival Child Welfare System (CWS) data, this study describes child health and wellbeing at their initial entrance into the CWS and subsequent returns. Associations between child wellbeing, health, placement stability, and frequency of returning to the system were also investigated. Results indicated most children were healthy and developmentally on target. In addition, emotional distress, behavioral concerns, and number of placements in the CWS were significantly correlated with placement stability. Future work should utilize the use of developmental assessments to systematically and reliably document the concerns for children in the system, and investigate factors contributing to stable placements. 相似文献

Since 2001, the federal Project Safe Neighborhoods initiative has instituted a comprehensive effort to reduce gun crimes in local communities across the United States. In South Carolina, the United States Attorney's Office for the District of South Carolina established Project CeaseFire, a localized response to reduce the prevalence of gun crime through targeted prosecution and increased public education. One element of Project CeaseFire was carried out by the South Carolina Department of Probation, Parole, and Pardon Services. The current study utilized a quasi-experimental design to compare firearm-related incidents among a random sample of offenders under community supervision prior to and after the implementation of the SCDPPPS CeaseFire program. Although incidents involving a firearm were rare, the current results did not indicate a reduction in firearm-related incidents among offenders entering supervision after the SCDPPPS CeaseFire program was implemented. Instead, an increase in firearm incidents was observed after CeaseFire implementation. Possible explanations for the observed results are offered along with limitations to the study and policy implications. 相似文献

Although Spanish-language media in the USA have grown rapidly since the turn of the century, little scholarship has been dedicated to the semiotic characteristics of these media. This study examines the visual representation of ideologies in 15 news photographs published in Spanish-language print media in the Midwest of the USA with the goals of understanding how ideologies are expressed visually in a culture that has received little treatment in the previous literature and of determining the potential for these photographs to challenge the negative semiotic treatment of Latin@ immigrants in the USA. Following a critical social semiotic approach, the analysis demonstrates how ideologies pattern around the inclusion and exclusion of Latin@s. These ideologies challenge and perpetuate the hegemonic structure, respectively, and as such, indicate the potential for local Spanish-language print media to challenge the negative semiotic representation of Latin@s in the USA while pointing to the need for future research of minoritized media using the social semiotics framework. 相似文献

Selection Bias and Continuous-Time Duration Models: Consequences and a Proposed Solution 总被引:3,自引:0,他引:3

This article analyzes the consequences of nonrandom sample selection for continuous-time duration analyses and develops a new estimator to correct for it when necessary. We conduct a series of Monte Carlo analyses that estimate common duration models as well as our proposed duration model with selection. These simulations show that ignoring sample selection issues can lead to biased parameter estimates, including the appearance of (nonexistent) duration dependence. In addition, our proposed estimator is found to be superior in root mean-square error terms when nontrivial amounts of selection are present. Finally, we provide an empirical application of our method by studying whether self-selectivity is a problem for studies of leaders' survival during and following militarized conflicts. 相似文献

Anecdotal evidence suggests that recent video-recorded police–citizen encounters have undermined police legitimacy and fueled civil unrest across the United States. Drawing from the process-based model of policing, social cognitive theory, and past research on media effects, we assess the influence of viewing cell phone videos of police–citizen encounters on perceptions of law enforcement. Using quasi-experimental methods and video footage of an actual police–citizen encounter captured on cell phones, the effects of viewing these videos are assessed using a series of repeated measure ANOVAs. Results indicate that viewing cell phone videos of police–citizen encounters significantly impacts perceptions of law enforcement, though little evidence of differing effects based on point-of-view, number of video exposures, or ordering of video exposures was found. The process-based model of policing should consider further incorporating the contributions of technology to provide a more holistic account of the factors influencing perceptions of police. 相似文献
