Criminal offending has many negative outcomes. Researchers have recently begun to consider the impact offending has on offenders' health, with a few studies focusing on differential mortality risk. Yet, prior research has been limited due to selective samples, restricted range of follow-up time period, limited set of explanatory variables, and lack of theoretical guidance. This paper examines the risk of early death among 411 South London males in the Cambridge Study in Delinquent Development followed into their late 50s. Attention is paid not only to differential risk of death between nonoffenders and offenders, but also to the risk within the population of offenders and through consideration of theoretical frameworks and associated predictor variables. Results show that high-rate chronic offenders evince the highest risk of death, an effect that continues even after controlling for childhood individual and environmental risk factors as well as participation in a range of analogous behaviors.  相似文献

Identifying failure mechanisms in skeletal tissue allows a deeper understanding of the effects of specific projectile impacts on bone. While ballistic trauma in flat bones is largely researched, knowledge of how long bones react to gunshot impacts is limited in the literature. The impacts of deforming ammunition appear to produce higher levels of fragmentation; however, these have not been studied in depth. This study compares the damage to femora bone by HP 0.357 and 9 mm projectiles constructed with both full and semi-metal jackets. Impact experiments were undertaken on a single-stage light gas gun involving the use of a high-speed video camera and full reconstruction of the bones to ascertain fracture patterns occurring in the femora. Higher degrees of fragmentation are likened to the presence of semi-jacketed HP projectiles than jacketed HP projectiles. The observations of external facing beveled edges are believed to be associated with the increased separation of the jacket and lead core of projectiles. Additionally, experimentation has shown that the amount of kinetic energy lost postimpact is likely related to the presence or the absence of a metal jacket on an HP projectile. The observed data, therefore, suggest that the composition, rather than the configuration, of a projectile affects the type and extent of the damage.  相似文献

The Iraqi High Tribunal (IHT), as a mechanism of transitional justice, took upon it a pioneering role within the Middle Eastern Region by prosecuting and convicting several high-ranking members of the former suppressive regime in Iraq. As part of this work, the IHT confronted the widespread impunity for and disregard of gender-based crimes, such as rape and other sexual violence, and took steps towards reforming the sector through its progressive statute and the specific acknowledgment of gender crimes within its judgments. It will be the aim of the following article to extend academic writings on Iraq, the IHT and gender, by providing insights into how the tribunal dealt with the issues of rape and sexual violence, the surrounding circumstances and how successful the IHT's recognition of these crimes proved for transitional justice in Iraq.  相似文献

This article discusses the opportunities and challenges associated with the use of quantitative participatory methods and participatory numbers for integrating locals’ and outsiders’ knowledge, as well as actions from the bottom-up and top-down, in development. It places emphasis on the contribution of quantitative participatory methods and participatory numbers to foster dialogue between a wide range of stakeholders, for example, local people, NGOs, government agencies and scientists, who usually seldom directly engage with each other. The article draws on case studies that discuss remittances and disasters in Samoa, and disaster risk reduction in the Philippines.  相似文献

Elements of social control theory were combined with social learning theory to construct a model of delinquency which specifies the manner in which parenting factors, social skills, value commitments, and problems in school contribute to association with deviant peers and involvement in delinquent behavior. The model was tested using a sample of 61 families, each of which included a seventh grader. Questionnaire responses and coded videotaped family interaction were employed as measures of study constructs. The results largely supported the proposed model.This work was supported by Research Grants DA 05347 from the National Institute on Drug Abuse, MH 43270 from the National Institute of Mental Health, and MCJ 190572 from the Bureau of Maternal and Child Health, Department of Health and Human Services.Received Ph.D. in sociology from Florida State University.

In forensic laboratories, increased extraction efficiency of trace evidence is paramount because analytical success is intrinsically dependent on the quantity of DNA recovered. Moreover, highly concentrated nucleic acids are vital for effective downstream analysis and high quality results. This study investigated the efficiency of extraction with the Qiagen® QIAamp® DNA Investigator kit, and explored improvements to the methodology that would maximise the recovery of low concentration forensic samples. Controlled amounts of starting cellular material were used to mimic trace (or low level) DNA deposits prior to DNA extraction with the Investigator kit. Addition of the provided carrier RNA along with conducting two successive elutions of 50 µL improved the net recovery of DNA to 95%. Concentration with centrifugal filters post-extraction were able to concentrate DNA but a large net loss was observed. For the concentration of historic, retrospectively extracted DNA, centrifugal methods are able to concentrate DNA extracts previously too dilute for analysis. These concentrated volumes, however are small, allowing for minimal downstream analysis attempts before the sample is exhausted.  相似文献

There is growing interest in the use of unconditional cash transfers as a means to alleviate poverty, yet little is known about the effects of such transfers in the U.S. This paper reports on the results of a randomized controlled study of a one-time $1,000 unconditional cash transfer in May 2020 to families with low incomes in 12 U.S. states. The families were receiving, or had recently received, Supplemental Nutrition Assistance Program benefits. We examine the impact of the cash transfer on five pre-registered outcomes (material hardship, mental health, parenting, child behavior, partner relationships) and several secondary outcomes (hardship avoidance, consumption, employment, benefit use). We find no statistically significant effects (powered to detect effects of 0.09 standard deviations) of the cash transfer on any outcomes for the full sample. In pre-specified exploratory analyses, we find significant reductions in material hardship (-0.17 standard deviations) among families with less than $500 of earnings in the previous month, roughly the bottom 50 percent of monthly earnings for the study sample.  相似文献

The early stages of adoptive placements are important in achieving successful long-term outcomes for adopted children and their families. This paper reports on findings from the Wales Adoption Study, in which adoptive parents shared their views and experiences of the legal and administrative processes in obtaining an adoption order. Parents described a range of difficulties that added to anxieties and delays. These arose mainly through poor communication about the steps in the legal process and avoidable administrative errors or oversights. Some parents also experienced lack of information and support regarding agreed contact arrangements and work with their child to help them make sense of their adoptive status.  相似文献
