Although some community violence research has examined the context of community violence, including the social, economic, and structural organization of neighborhoods, more needs to be learned about family, school, and community-level factors that may promote and lessen the incidence and prevalence of community violence. In addition, further research is needed on various social, environmental, and contextual factors hypothesized to protect youth from exposure. This article (a) reviews and examines the relation between neighborhood context and risk of violence exposure, (b) reviews current literature on predictors of community violence and mental health and behavioral consequences for children and families adversely affected by community violence, (c) examines sources of resilience and community strengths that extend beyond the individual, (d) discusses the contributions and limitations of current conceptualizations of risk and resilience, and (e) highlights directions for future research. Information from this review can inform community and government efforts to lessen community violence through prevention and treatment.  相似文献

Purpose

Psychopathy and psychopathic personality traits (PPT) have been linked to a long list of negative life outcomes. To date, however, few studies have provided a systematic analysis of whether psychopathic personality traits contribute to increased health burden. The current study was designed to address this gap in the literature.

Method

This study analyzed data from the National Longitudinal Study of Adolescent Health and employed a measure of PPT derived from the five-factor model of personality. Analyses were conducted using OLS, logistic, and Poisson regression techniques.

Results

The results revealed that relatively higher scores on psychopathic personality traits were associated with a slight increase in a wide range of negative health outcomes. These significant associations were detected for both males and females.

Conclusions

We speak to the importance of these findings for the potential to reduce health burden among psychopaths and those who score relatively high on measures of psychopathic personality traits.  相似文献

Purpose

Failing to deal with missing data patterns effectively may result in biased parameter estimates and ultimately may produce inaccurate results and conclusions. The vast majority of criminological research has addressed this issue with listwise deletion (LD) and multiple imputation (MI) techniques. Identifying the specific covariates that directly contribute to patterns of missingness is highly important in deciding which technique to use. One of the more surprising omissions from the identified list of covariates is the potential role of genetic influences in the development of missingness.

Methods

The current study addresses this gap in the literature by estimating genetic (A), shared environmental (C), and the nonshared environmental (E) influences on missingness across measures of delinquency and self-control within a longitudinal sample of twin and sibling pairs.

Results

The results indicated that genetic influences explain a significant portion of the variance in missing values related to both delinquency and self-control.

Conclusions

Current methodological techniques aimed at addressing missing data should be amended to take genetic influences into account. Such modifications and the implications of the findings for future research are discussed.  相似文献

Chinese culture holds very different beliefs regarding sex offenses, violence against women and punishment against offenders. Little is known however about Chinese attitudes toward sex offenders and sex offending policies. The aim of this study was to validate the Community Attitude toward Sex Offender Scale in the Chinese cultural context. Results from a territory-wide telephone survey in Hong Kong revealed a three factor structure that measures perceptions of sex offenders’ social isolation, deviancy and punitive attitudes toward sex offenders. The scale has been renamed as the simplified Community Attitude toward Sex Offender Scale-Chinese (CATSO-C). Each subscale and the total scale showed acceptable internal reliability. This instrument has implications for future cross-cultural studies as well as professionals that work with sex offenders.  相似文献

To outsiders, prisons vacillate between visions of regimented order and anarchic disorder. The place of rules in prison sits at the fulcrum between these two visions of regulation. Based on 131 qualitative interviews with correctional officers across four different prisons in western Canada, we examine how correctional officers understand and exercise discretion in prison. Our findings highlight how an officer's habitus shapes individual instances of discretionary decision‐making. We show how officers modify how they exercise discretion in light of their views on how incarcerated people, fellow officers, and supervisors will interpret their decisions. Although existing research often sees a correlation between “rule‐following” by incarcerated individuals and official statistics on such misdeeds, our data highlight that official statistics on rule violations do not easily represent the rate or frequency of such misbehavior. Instead, these numbers are highly discretionary organizational accomplishments. Our findings advance an appreciation for correctional officer discretion by focusing on the range of factors officers might contemplate in forward‐looking decisions about applying a rule and how they rationalize the nonenforcement of rules.  相似文献

This research examines the utility of patella outline shape for matching 3D scans of patellae to knee radiographs using elliptical Fourier analysis and subjective methods of human visual comparison of patellae across radiographs for identification purposes. Repeat radiographs were captured of cadaver's knees for visual comparison before patellae were extracted and skeletonized for quantitative comparisons. Quantitative methods provided significant narrowing down of the candidate pool to just a few potential matches (<5% of original sample), while the human analysts showed high capacity for correctly matching radiographs, irrespective of educational level (positive predictive value = 99.8%). The successful computerized matching based on a single quantified patella trait (outline shape) helps explain the potency achieved by subjective visual examination. This work adds to a growing body of studies demonstrating the value of single isolated infracranial bones for human identification via radiographic comparison.  相似文献

We examine whether Stephen Sandford's (2006 Sandford, S. 2006b. “Too many people, too few livestock: the crisis affecting pastoralists in the Greater Horn of Africa”. Accessed at: http://www.future-agricultures.org/pdf%20files/Sandford_thesis.pdf [Google Scholar]b) ‘too many people, too few livestock’ thesis for the Greater Horn of Africa applies to West Africa. In a comparative study of seven pastoral systems across West Africa we found that pastoralists have generally successfully adapted to pressures on grazing resources. We describe three adaptive strategies: 1) integration and intensification in the Sudanian zone; 2) movement to the Sub-Humid zone; and 3) extensification in the Sahelian zone. We end by proposing four interrelated factors that account for the differences in pastoral systems between West Africa and the Greater Horn of Africa.  相似文献
