We examine the understudied link between mental/physical health problems and their relationship with perceived unsafety via higher levels of vulnerability. We examine this relationship by linking data at the individual-level, the neighborhood-level, and the county-level using the Portraits of American Life Survey (PALS). Using this data we examine the effect of individual and neighborhood conditions on perceived safety while controlling for county-level crime rates. Findings indicate that higher numbers of physical impairment and mental health issues are independently related to higher levels of perceived unsafety. Both mental and physical health problems are associated with higher levels of fear. These higher levels of vulnerability then directly contribute to higher levels of feeling of unsafety. Unlike past research, we find a mental health link to fear of crime that cannot be explained by physical impairments. 相似文献

This article charts how security‐cleared counsel have been constructed as a mechanism for managing the tension between security and fairness in secret trials and transferred across national boundaries as an example of ‘best practice', before going on to evaluate recent cross‐cultural and transnational research on this ‘best practice'. Particular attention is paid to the central role played by the European Court of Human Rights (ECtHR) in promoting the role of ‘special advocates’ and a contrast is made between the methodologies deployed by the Court and those used in recent research to identify and problematize ‘best practice’ within the closed world of security‐cleared counsel. The article then goes on to explore the relationship between ‘best practice’ and procedural tradition and argues that normative solutions advancing ‘best practice’ need to pay careful attention to the procedural contexts and cultures in which they are embedded. 相似文献

The chemical composition of fingermarks could potentially be important for determining investigative leads, placing individuals at the time of a crime, and has applications as biomarkers of disease. Fingermark samples containing triacylglycerols (TAGs) and other components were analyzed using laser desorption/ionization (LDI) time-of-flight mass spectrometry (TOF MS). Only LDI appeared to be useful for this application while conventional matrix-assisted LDI-TOF MS was not. Tandem MS was used to identify/confirm selected TAGs. A limited gender comparison, based on a simple t-distribution and peaks intensities, indicated that two TAGs showed gender specificity at the 95% confidence level and two others at 97.5% confidence. Because gender-related TAGs differences were most often close to the standard deviation of the measurements, the majority of the TAGs showed no gender specificity. Thus, LDI-TOF MS is not a reliable indicator of gender based on fingermark analysis. Cosmetic ingredients present in some samples were identified. 相似文献

Although sexual minority (SM) youth are at an increased risk for being bullied and experiencing depression, it is unclear how caregiver support is interrelated with those variables. Therefore, we sought to assess: (a) the prevalence of nonphysical bullying, depressive symptomatology, and caregiver support among heterosexual and SM girls, (b) the association between caregiver support and bullying in both groups, and (c) whether sexual orientation moderates the interactive effect of caregiver support and bullying on depressive symptoms. Data come from a survey of students in 22 Boston public high schools; 99 of the 832 girls in the analytic sample were SM. We used chi-square statistics to examine group differences, and multiple regression to estimate the association between the caregiver support, sexual orientation, being bullied, and depressive symptomatology. SM girls reported similar levels of caregiver support as heterosexual girls, but reported higher levels of depressive symptomatology. They were also more likely to report nonphysical bullying. Tests for interactions were not statistically significant, suggesting that bullying, caregiver support, and sexual orientation are independently associated with depressive symptomatology. 相似文献

This study examines the psychological impact of viewing disturbing media on investigators engaged in computer forensics work.
Twenty-eight federal law enforcement personnel who investigate Internet child pornography cases completed measures of secondary
traumatic stress disorder (STSD) and burnout. Substantial percentages of investigators reported poor psychological well-being.
Greater exposure to disturbing media was related to higher levels of STSD and cynicism. STSD and burnout scores were related
to increased protectiveness of family, reliance on co-workers, general distrust, and turnover intentions. On a positive note,
investigators scored high in professional efficacy, indicating they feel their work makes a difference. Furthermore, personnel
with supportive relationships scored lower on both STSD and burnout. 相似文献

Introduction of the construct “Dangerous and Severe Personality Disorder” (DSPD) by the UK Home Office and Department of Health has provoked strong debate and opposition. Its aims and that of proposed subsequent legislation was to enhance public protection by identifying and detaining a minority of persons with severe personality disorder who pose a high risk of serious sexual/violent offending. The most serious criticism was the ethical implication of allowing indefinite detention of people without criminal convictions. More recently, policy emphasis has shifted towards treatment. 1396 male prisoners serving sentences of 2+ years for sexual/violent offenses were prospectively interviewed (personality disorders, psychopathy, and risk) at a mean follow-up of 2 years. The prevalence of DSPD was 15%. Significantly more re-offended. Five DSPD offenders would need treatment to prevent one violent act. Based on an estimate of attributable risk, successful treatment of DSPD could reduce violent re-convictions among DSPD offenders by 71% and violent/sexual re-offenses in the prison population by 27%. DSPD criteria correctly identify high risk prisoners but primarily through risk-related demographic features. DSPD does not accurately identify serious sexual/violent re-offenders. The DSPD programme may reduce major violent re-offending if treatment interventions prove effective. 相似文献
