The aim of the present study was to assess the psychometric properties of the Narcissistic Personality Inventory (NPI) and two of its short forms (NPI-16 and NPI-13) among a Portuguese sample of male incarcerated juvenile offenders (N?=?221). Of these, only the NPI-13 short version demonstrated a good fit in terms of its factor structure. The NPI-13 also showed promising psychometric properties in terms of its internal consistency, convergent validity, discriminant validity, and criterion-related validity. Statistically significant associations were found with age of crime onset, crime seriousness, conduct disorder symptoms, alcohol abuse, and cannabis use. These findings justify the use of the NPI-13, especially its Entitlement/Exploitativeness dimension, among incarcerated male youths.  相似文献

The unusual appearance of crystalline fat structures was observed during the postmortem examination of a motor vehicle accident victim. The crystal structures were characterized using Fourier transform infrared spectroscopy and x-ray diffractometry. The structures were found to be made of triacylglycerols, a dominant lipid structure found in human adipose tissue, capable of forming various polymorphic structures. The morphology of the crystalline material was found using both techniques to be predominantly the beta' form of triacylglycerols. The accelerated growth of such triacylglycerol morphology has been observed as a result of shear stresses in other studies involving edible fats. As a result of the findings of this study, it is proposed that increased shear forces may be responsible for the formation of the unusual fat structure found in the victim. An understanding of the effect of forces on the structure of body fat in high-impact collisions can potentially assist in verifying a high-velocity impact.  相似文献

Objectives

Research indicates that victims who make changes to their risky behavioral routines are better able to avoid being victimized again in the future. Nevertheless, some victims’ abilities to change their behaviors may be limited by what Hindelang et al. in Victims of personal crime: an empirical foundation for a theory of personal victimization. Ballinger, Cambridge (1978) referred to as “structural constraints.” To assess this issue, we determine: (1) whether victims who reside in communities characterized by structural constraints (e.g., concentrated disadvantage) are more likely to continue engaging in risky behaviors (e.g., offending, illicit drug use, and getting drunk) after being victimized; and (2) whether victims who continue to engage in risky lifestyles have an increased likelihood of repeat victimization.

Methods

Ten waves of data (spanning nearly 7 years) from the Pathways to Desistance Study are used, and multilevel models are estimated to examine changes to risky lifestyles and repeat victimization among a subsample of victims.

Results

Findings indicate that community-level structural constraints impose limits on the changes that victims make to their risky lifestyles, and that these changes influence repeat victimization.

Conclusions

We conclude that, in the context of repeat victimization, structural constraints are both real and consequential, and that future theory and research should continue to explore how context shapes and influences victims’ behavioral routines.

This study sought to examine the relationship between homelessness and behavior problems among a community-based sample of youth in North Texas. Data were obtained from a cross-sectional, probability sample of households and a targeted sample of homeless families in Dallas, Texas, with children older than 5 years old (N?=?5232). Parents were asked to report five behavior problems on behalf of their children including arrest or trouble with police, academic problems, behavior problems at school, suspension, and suicide attempts. Logistic and negative binomial regression procedures were used to examine the relationship between homelessness and behavior problems. Youth exposed to homelessness were 36% (OR?=?1.63; 95% CI 1.00–1.85) more likely to exhibit any kind of behavior problems than youth who had never experienced homelessness. Homeless youth had 5.51 times the odds of arrest (95% CI 2.60–11.68), 1.74 times the odds of academic problems (95% CI 1.24–2.43), and more than 3 times the odds of suicide attempts (95% CI 1.46, 7.61) than youth who had never been homeless. Homelessness was associated with higher rates of problem behavior, including arrests, academic problems, and suicide attempts. Because homeless youth are commonly enrolled in school and present at health care clinics and emergency departments, clinics and schools may aid in the identification of homeless youth, as well as referral to care. In this way, clinicians may help reduce the burden of behavioral problems that disproportionately affect homeless youth.  相似文献

ABSTRACT

This study employs a mixed methods analysis of exit survey data gathered from public child welfare employees at their completion of a Title IV-E funded MSW program, distinct because it was initiated during a period of major reform and permitted students to continue employment during their studies. Findings suggest that opportunities for growth and manageable levels of stress were associated with intentions to stay and engagement with the work, reflected in respondents’ positive perceptions of their roles in the work environment and their retrospective assessments of the impact of their social work education.  相似文献
