ABSTRACT Drawing on the education production function literature, we examine the short-run impact of comprehensive education reforms in Barbados on primary school student outcomes. Using a variety of specifications to test the robustness of our results, we find modest and mixed changes in student test scores. Our findings are discussed in the context of management challenges that resulted from the need to coordinate a multi-faceted project in a rapidly developing nation; alignment of goals and schedules of two multi-national development banks, the Ministry of Education, Youth Affairs and Sports (MES), and the Government of Barbados; and, a very rapidly changing information technology environment that led, in part, to changes in planned capital improvements in schools, equipment needs, and had implications for teacher training. 相似文献

Aim
This study determined the extent to which alcohol and marijuana use during adolescence mediates the relation between transmissible risk for substance use disorder (SUD) and lifetime number of different types of violent offenses.Methods
The transmissible liability index was administered to 359 10-12 year old youths who were tracked to 22 years of age. Past year frequency of alcohol and marijuana consumption was longitudinally tracked to age 22 at which time lifetime violent offenses was recorded.Results
Rate of increase in marijuana use mediated the association between transmissible risk and lifetime number of different types of violent offenses. No association was found between past year frequency of alcohol use and violent offenses.Conclusions
Prevention directed at lowering the psychological characteristics associated with transmissible risk for SUD may also reduce violent offending. 相似文献55.

Fracture matches are considered the strongest conclusion in the forensic examination of rigid materials, such as glass, metal, and paint. However, publications that support the fracture matching of polymeric films, such as tape backings, are limited. This study was designed to determine the validity and error rate associated with conducting end-match (fracture match) examinations on vinyl electrical tape. Test designs varied the source roll of tape, test preparer, or mode of separation from the roll. Results indicated that each affected the resulting severed tape ends. The analysts examining the end matches also had an effect on the results. Eight end matches in the study were not identified by the initial analysts and were considered inconclusive. One end match was misidentified, resulting in one false positive and an error rate of 0.049%. These results support a comprehensive physical and chemical tape comparison regardless of indications of an end match. 相似文献

This article is a longitudinal investigation of the relationships between maternal victimization, maternal functioning, and children's behavior and development. Participants include 203 mother-child dyads from a low-income population recruited from pediatric primary care clinics. Data are collected when children are 4 and 8 years of age. Child outcomes are evaluated using maternal, teacher, and child self-report and objective measures of cognitive and academic functioning. Maternal victimization history is associated with maternal depressive symptoms, low levels of maternal social support, child internalizing and externalizing behavior problems, and low levels of child socialization. Child behavior problems identified at age 4 are enduring and persist to age 8. The effects of maternal victimization history on both internalizing behavior problems and socialization are mediated by maternal depressive symptoms. The effects of maternal depressive symptoms on externalizing behavior problems, socialization, and anger are mediated by maternal social support. Clinical implications of findings are discussed. 相似文献

The Anti-Stalking Training Evaluation Protocol (ASTEP) was developed to provide Safe Horizon, a large victim service provider, with an opportunity to evaluate and improve its anti-stalking training program. This report presents the results of this effort to measure Safe Horizon staff's knowledge and general perceptions about stalking, and to assess the impact of anti-stalking training on knowledge about the anti-stalking law, and stalking in general. Although these trainees appeared familiar with stalking issues, they were able to benefit from information about different types of stalkers and stalking, and about the legal options available to victims. The implication of the findings is that, if relatively well-informed staff members of a large victim services agency can benefit from training about stalking behavior, anti-stalking legislation and the needs of stalking victims, there is almost certainly a need for such training among a wider population of victim service providers, law enforcement professionals, and the general public. 相似文献
