Ex-armed forces personnel constitute the largest known occupational group in prison but there is little evidence regarding their mental health, or substance misuse, needs. A total of 105 participants were interviewed and measures assessing symptoms of common mental health (CMH) problems and substance misuse were completed along with a review of their health care records. Forty (38%) participants screened for current CMH problems (CCMH) and high levels of dual symptomology and alcohol misuse were assessed. Thirty-nine (37%) had a mental health diagnosis recorded, most commonly for post-traumatic stress disorder (PTSD), depression and personality disorder. Those who screened for a CCMH problem were more likely to have pre-service vulnerability to negative health outcomes and those with dual symptomology were more likely to have experienced deployment during their service. Findings suggest the mental health needs of this group are similar to the general prison population. Potentially higher prevalences of PTSD and alcohol misuse may direct service provision.  相似文献

Objectives

This study proposes a theoretical framework for understanding two empirical findings from gang research: (1) gangs are generally racially homogenous, even in heterogeneous environments, and (2) gang violence tends to be intra-racial. We draw from the extensive literature on street gangs as well as from research on group formation and status-enhancing behavior to develop a theoretical model of gang formation.

Methods

Using game theory, we model the simultaneous decisions of individuals to commit status-enhancing acts of violence and to seek protection by joining a gang. We then conduct computer simulations to examine the resulting patterns of violence and gang composition.

Results

We demonstrate that as long as some social distance exists between racial groups in a community, gang violence will be intra-racial and gangs will be homogenous. We find that our results are robust to a number of simple variations of the model and allow us to generate several hypotheses about the nature of gang formation and patterns of violence.

Conclusions

When violence is motivated by socially constructed rewards, socially closer targets are likely to yield greater rewards. In such a system, individuals must reduce their likelihood of victimization by entering a social contract of non-violence (i.e. gang membership) with individuals who might view them as status-enhancing targets (i.e. socially close individuals). The result is that gangs are made up of socially close individuals interested in attacking other socially close individuals. Therefore, gangs tend to be racially homogenous and violence is overwhelmingly intra-racial.

The aim of this paper is to extend some of the theoretical concerns that Marcus Felson (2006) opens up in Crime and Nature by considering the contribution of post humanist political ecology to the construction of crime and nature that he proposes. Post humanism problematises dichotomous understandings of nature and culture as well as related binaries that follow from that division, suggesting that dominant assumptions about nature and the non human undermine antiracist and feminist efforts. While Felson (2006) takes steps towards troubling the nature/culture binary, he fails to question the constructed character of crime and crime prevention, thereby leaving unarticulated a critical problematisation of the exclusionary logics that underlie dominant practices and ways of thinking as race, sex, class and species fundamentally determine the nature of criminological knowledge. Abstracting crime from social context produces a partial analysis as spaces are reduced to their supposed propensity for criminal activity and some spaces are produced as always already criminal. Without examining and understanding how power relations intersect in the context of crime it is difficult to alter those relations to promote social justice.  相似文献

The majority of microfluidic devices used as a platform for low‐cost, rapid DNA analysis are glass devices; however, microchip fabrication in glass is costly and laborious, enhancing the interest in polymeric substrates, such as poly (methyl methacrylate) (PMMA), as an inexpensive alternative. Here, we report amplification in PMMA polymerase chain reaction (PCR) microchips providing full short tandem repeat profiles (16 of 16 loci) in 30–40 min, with peak height ratios and stutter percentages that meet literature threshold requirements. In addition, partial profiles (15 of 16 loci) were generated using an ultrafast PCR method in 17.1 min, representing a ~10‐fold reduction in reaction time as compared to current amplification methods. Finally, a multichamber device was demonstrated to simultaneously amplify one positive, one negative, and five individual samples in 39 min. Although there were instances of loci dropout, this device represents a first step toward a microfluidic system capable of amplifying more than one sample simultaneously.  相似文献

Careful users of CMP party position data should take the uncertainty of position estimates into account. We compare and evaluate two current approaches that provide error estimates for party positions. Researchers of the CMP group identify measurement error in quantitative content analysis as the cause of uncertainty about position estimates, whereas a second approach by Benoit et al. (2009) attributes the uncertainty of position estimates to a stochastic generation of election programs. We illustrate the commonalities and differences of these approaches and provide two empirical applications, the identification of the left–right order of parties and of policy shifts by parties, using CMP data for 25 countries. Despite conceptual differences, results in these applications are surprisingly similar.  相似文献

Within the context of acute public spending cuts and the increasing push towards localism, the UK government is increasingly looking outwards to community- and citizen-led action for solutions to long-term social problems and to take on public services. The extent to which these groups have the capacity and willingness to take on politicised roles beyond their purpose and function is, however, not well understood. By reflecting on findings primarily from a street-level mapping project, in this paper discussion focuses on the potential implications arising from grassroots' co-option.

La société civile au niveau de la base populaire à la croisée des chemins : rester sur le chemin de l'indépendance ou prendre la voie du gouvernement britannique vers le localisme ?

Dans le contexte des profondes coupes sombres opérées dans les dépenses publiques et de la poussée croissante vers le localisme, le gouvernement britannique se tourne de plus en plus vers l'extérieur, vers des actions menées par les communautés et les citoyens pour résoudre les problèmes sociaux à long terme et se charger des services publics. La mesure dans laquelle ces groupes ont les capacités et la volonté nécessaires pour assumer des rôles politisés qui dépassent leur finalité et leur fonction n'est pas, toutefois, bien comprise. En réfléchissant sur les constatations faites principalement dans le cadre d'un projet de cartographie au niveau des rues, la discussion de cet article porte sur les implications potentielles de la cooptation de la base populaire.

La sociedad civil de base en la disyuntiva: ¿mantener el camino de la independencia o tomar la ruta del gobierno del Reino Unido hacia el localismo?

En un contexto de severos recortes en el gasto público y de creciente impulso hacia el localismo, el gobierno del Reino Unido está fomentando cada vez más que las comunidades y los ciudadanos impulsen acciones tendientes a solucionar longevos problemas sociales y que se hagan cargo de los servicios públicos. Sin embargo, no se comprende bien hasta qué punto dichos grupos tienen la capacidad y la disposición de asumir roles politizados más allá de sus objetivos y de su función. A partir de reflexiones en torno a las conclusiones provenientes principalmente de un proyecto de mapeo a nivel de calle, el presente artículo se centra en analizar las posibles implicaciones que podrían surgir de la cooptación de los grupos de base.

Sociedade civil de base na encruzilhada: permanecendo no caminho para a independência ou voltando-se para a rota do governo do Reino Unido em direção ao localismo?

Dentro do contexto de significativos cortes nos gastos públicos e um empenho crescente em direção ao localismo, o governo do Reino Unido está cada vez mais olhando para fora para ações coordenadas pela comunidade – e cidadãos – para soluções de problemas sociais de longo prazo e contratação de serviços públicos. Porém, não se sabe muito bem até que ponto estes grupos têm capacidade e disposição de adotar funções politizadas além de seu propósito e função. Ao refletir sobre os resultados obtidos principalmente a partir de um projeto de mapeamento realizado nas ruas, a discussão deste artigo concentra-se nas implicações em potencial que surgem da opção conjunta de base.  相似文献

The Qualified Lawyers Transfer Scheme (QLTS) provides a route for lawyers from other jurisdictions and barristers from England and Wales to qualify as solicitors in England and Wales. One of the three tests in the QLTS, the Multiple Choice Test (MCT), uses multiple choice questions to examine the syllabus of the qualifying law degree together with some pervasive subjects from the Legal Practice Course. This paper examines the MCT in detail. Particular attention is paid to the format and structure of the questions. We describe the detailed editing which each question goes through before it is used, the statistical analysis and review which take place after an exam, and the rationale for these processes. An explanation is given of what reliability and accuracy mean and how they are measured statistically. There is also an explanation of the “Angoff method” by which pass marks are set. Finally, the paper reports on the first four sittings of the MCT and their statistical results including their reliability and accuracy. Use of the multiple choice test, though well established for examining applied knowledge in medicine and in law in other jurisdictions, is a radical departure for the assessment of law in England and Wales. The experience of QLTS has shown that a carefully constructed multiple choice test of a suitable length can assess the qualifying law degree content both reliably and accurately.  相似文献
