Miniaturization of capillary electrophoresis onto a microchip for forensic short tandem repeat analysis is the initial step in the process of producing a fully integrated and automated analysis system. A prototype of the Berkeley microfabricated capillary array electrophoresis device was installed at the Virginia Department of Forensic Science for testing. Instrument performance was verified by PowerPlex 16 System profiling of single source, sensitivity series, mixture, and casework samples. Mock sexual assault samples were successfully analyzed using the PowerPlex Y System. Resolution was assessed using the TH01, CSF1PO, TPOX, and Amelogenin loci and demonstrated to be comparable with commercial systems along with the instrument precision. Successful replacement of the Hjerten capillary coating method with a dynamic coating polymer was performed. The accurate and rapid typing of forensic samples demonstrates the successful technology transfer of this device into a practitioner laboratory and its potential for advancing high-throughput forensic typing. 相似文献
ABSTRACT Criminologists have been interested in the gap in reported levels of fear of crime between men and women for decades. Our study advances and empirically tests the hypothesis that gender identity is an important mechanism that accounts for the gap in fear of crime between men and women. Specifically, the current study incorporates Magliozzi, Saperstein, and Westbrook’s gradational measures of masculinity and femininity to test if these variables are related to fear of crime. Statistical analyses reveal that masculinity is negatively and significantly associated with fear of crime, suggesting that men may be doing gender in reporting fear of crime by suppressing their expression of fear when responding to survey items related to fear of crime. Additionally, the inclusion of the measures of masculinity and femininity in our statistical model reduces the effect of sex to non-significance. 相似文献
This study aims to identify how American major newspapers frame the BP's Gulf of Mexico oil spill crisis in 2 major daily newspapers, The New York Times and USA Today. In addition, this study exams what kinds of themes are used in conjunction with news frames for covering the BP oil spill crisis in the Gulf of Mexico. 489 articles were analyzed, 353 articles for The New York Times and 136 articles for USA Today. In a pretest, this study identified 6 main frames and 9 themes used by the collected news articles, and these 6 frames and 9 themes were used to analyze the collected news articles. Among 6 frames, the most common primary frame in the New York Times was attribution of responsibility, as compared to the most common primary theme in USA Today, solution. On the other hand, the most common theme in The New York Times was stopping the oil, as opposed to the most common theme found in USA Today, politics. 相似文献
This research informs our understanding of the technology commercialization process in university spinoffs, focusing in particular on student involvement in the early phases of the spinoff development process and on the impact of the larger university ecosystem. Detailed case studies indicate that graduate and post-doctoral students are important participants in university spinoffs. We offer a typology of spinoff development with four pathways, based on the varying roles of faculty, experienced entrepreneurs, PhD/post-doctoral students, and business students. The effects of the larger university ecosystem, beyond the university technology transfer office and the university’s commercialization policies, are also considered, including an examination of programs and practices that may influence this process. We close with a discussion of guidelines for technology transfer and spinoff development at universities, based on the findings of this research. 相似文献
This study explores the ability of inmate cynicism to mediate the relationship between perceptions regarding quality of treatment and inmate misconduct in a prison setting. Using a sample of inmates from prisons in South Korea, the generalizability of the process-based model is tested. Also, the indirect effect of quality of treatment on inmate misconduct through cynicism is estimated using a bias-corrected bootstrapped mediation analysis. The findings show that quality of treatment was negatively and significantly associated with inmate misconduct in South Korean prisons. Additionally, results indicate that the quality of treatment and social support are significant predictors of inmate cynicism. Finally, a regression-based path analysis reveals that cynicism mediates the relationship between quality of treatment and inmate misconduct. While quality of treatment was found to predict inmate misconduct significantly, mediation analyses support the hypothesis that inmate cynicism partially mediates this association. The findings suggest that correctional policies should pay more attention to reducing inmates’ cynicism.
