Background
Neighbourhood segregation has been described as a fundamental determinant of physical health, but literature on its effect on mental health is less clear. Whilst most previous research has relied on conceptualized measures of segregation, Northern Ireland is unique as it contains physical manifestations of segregation in the form of segregation barriers (or “peacelines”) which can be used to accurately identify residential segregation.
Methods
We used population-wide health record data on over 1.3 million individuals, to analyse the effect of residential segregation, measured by both the formal Dissimilarity Index and by proximity to a segregation barrier, on the likelihood of poor mental health.
Results
Using multi-level logistic regression models we found residential segregation measured by the Dissimilarity Index poses no additional risk to the likelihood of poor mental health after adjustment for area-level deprivation. However, residence in an area segregated by a “peaceline” increases the likelihood of antidepressant medication by 19% (OR=1.19, 95% CI: 1.14, 1.23) and anxiolytic medication by 39% (OR=1.39, 95% CI: 1.32, 1.48), even after adjustment for gender, age, conurbation, deprivation and crime.
Conclusions
Living in an area segregated by a ‘peaceline’ is detrimental to mental health suggesting segregated areas characterised by a heightened sense of ‘other’ pose a greater risk to mental health. The difference in results based on segregation measure highlights the importance of choice of measure when studying segregation.

This study investigated, retrospectively, whether recidivism in a sample of court-ordered'graduates of an alcohol education and awareness program could be predicted. This alcohol education program was based on adult education principles and was philosophically akin to the thoughts of Drs. Jack Mezirow, Stephen Brookfield, and Patricia Cranton. Data on the sample of 214 Halton IDEA (Impaired Driver Education and Awareness) graduates were entered into a spread sheet. Descriptive statistics were generated. Each of the 214 program graduates had taken several tests during the course of the IDEA program. These tests measured knowledge, attitude about impaired driving, and degree of alcohol involvement. Test scores were analyzed to determine whether those IDEA graduates who recidivated differed in any measurable way from those who had no further criminal convictions after a period of at least three years. Their criminal records were obtained from the Canadian Police Information Centre (CPIC). Those program graduates who reoffended were compared to the vast majority who did not reoffend. Results of the study indicated that there was no way to determine who would recidivate from the data that were collected. Further studies could use a qualitative model. Follow-up interviews could be used to determine what impact, if any, attendance at the IDEA program had on the life of the graduates.

Dans ce mémoire, les armes à feu impliquées dans la commission de crimes sont étudiées à partir de leur mobilité spatio-temporelle. Afin d’opérationnaliser cette mobilité, deux mesures spécifiques ont été créées, soit le « temps-au-recouvrement » et la « distance-au-recouvrement ». Ces mesures permettent d’analyser les répercussions des armes à feu en circulation illégale sur la formation du marché illégal dans le territoire québécois. Des analyses descriptives ont d’abord été effectuées dans cette étude à partir de trois segments de la banque de données québécoise des armes à feu recouvrées : la banque complète, les armes à feu impliquées dans la commission de crimes et les armes volées. Le sous-groupe de 501 d’armes à feu volées est le seul qui a été soumis à des analyses de régressions multiples sur la mobilité puisque ces armes sont les seules permettant d’avoir plus d’informations sur leur mouvement antérieur au recouvrement par les autorités policières. Les résultats montrent qu’il y a une mobilité spatio-temporelle plus importante chez les armes de poing, celles impliquées dans les crimes de marché, les armes non-enregistrées ainsi que celles sans restriction. Afin de mieux comprendre la dynamique des armes volées, le statut de l’enregistrement s’avère la variable la plus importante puisqu’elle permet de déterminer à quel point ces armes vont être enracinées dans le marché illégal au Québec. Effectivement, les armes volées non-enregistrées sont plus susceptibles de converger vers les marchés criminels, ce qui augmente considérablement leur « durée » de vie et leur mobilité dans la province.

L’effet de la disponibilité des AAF sur le taux d’homicide est un sujet qui n’a jamais su faire consensus au sein du corpus scientifique. En tenant compte des réalités canadiennes relatives à l’utilisation d’une arme à feu dans les homicides, la présente étude évaluera la relation entre la disponibilité des armes à feu et le taux d’homicide au Canada, par le biais de séries chronologiques simples et multiples. Les données utilisées dans le cadre de la recherche proviennent de l’Enquête sur l’homicide effectuée par Statistiques Canada, du programme de la déclaration uniforme de la criminalité (DUC), des catalogues Juristats et des catalogues produits par Statistiques Canada sur les causes de décès au pays. Globalement, des relations positives et significatives sont observées entre les deux phénomènes au temps t. Au temps t-1 et t-2, des relations négatives sont observées entre la disponibilité des armes à feu et le taux d’homicide, tandis que des relations positives sont constatées entre le taux d’homicides et la disponibilité des armes à feu. Les résultats confirment que le taux d’homicide et la disponibilité des armes à feu sont des phénomènes qui s’influencent mutuellement dans le temps. En raison du niveau d’agrégation des données, il n’est pas possible de départager l’influence respective des deux phénomènes. Les résultats soutiennent toutefois davantage les thèses de l’autoprotection et de l’autodéfense. Enfin, les résultats montrent l’importance de développer des indices de disponibilité propres aux deux types d’armes à feu impliqués dans les homicides au Canada.

The scientific literature often mentions that there is a statistical connection between alcohol and drug consumption and criminal behaviour. However, there is little information available which would make it possible to quantify this connection, and specify the impact that drugs and alcohol have on criminal behaviour. Consumption of psychoactive substances has two major effects: intoxication and addiction. These effects are related, respectively, to the psycho-pharmacological and economic-compulsive models of the connection between drugs and crime. The first model associates drug use and intoxication with a decrease in cognitive functions and a lack of self-control, leading to aggressive impulses, violence and lack of inhibitions. The second model refers to the huge costs that are associated with being addicted to certain drugs. A person addicted to these drugs would need to engage in lucrative criminal activities in order to pay for them. This article explores and attempts to further define the links between alcohol, illicit drugs and criminal behaviour, taking into account the types of drugs consumed and the types of criminal behaviour displayed.

This paper asks whether school based management may help reducing risky sexual behavior of teenagers. For this purpose we use student level data from Bogot´a to identify students from Concession School (CS), who are enrolled in public education system with a more school management autonomy at school level, and to compare them with those students at the traditional public education system. We use propensity score matching methods to have a comparable sample between pupils at CS and traditional schools. Our results show that on average the behavior of students from CS do not have a sexual behavior that differs from those in traditional public schools except for boys in CS who have a lower probability of being sexual active. However, there are important differences when heterogeneity is considered. For example we find that CS where girls per boys ratio is higher have lower teenage pregnancy rates than public schools with also high girls per boys ratios. We also find that teachers’ human capital, teacher-pupil ratio or whether school offers sexual education are also related to statistically significant differences between CS and traditional public schools.

Firms’ compensation practices affect the protection of investors’ interests and the degree of economic inequality by changing the stakes of engaging in appropriation activities versus respecting the status quo. We use a general equilibrium model where workers can either work peacefully or join a guerrilla movement that expropriates entrepreneurs. If workers are peaceful, they receive a competitive wage. If they join a guerrilla movement, they receive a share of the appropriated wealth, which depends positively on the number of guerrilla members. In this framework, we find one low-income, low-wage equilibrium with guerrilla activity and one peaceful, high-income, high-wage equilibrium. The peaceful equilibrium can be reached through redistribution policies, which can be implemented at the firm level. In essence, through their compensation policies entrepreneurs, not the state might be able to protect their assets against expropriation and simultaneously control the internal principal-agent problem.

We document the existence of a Crime Kuznets Curve in US states since the 1970s. As income levels have risen, crime has followed an inverted U-shaped pattern, first increasing and then dropping. The Crime Kuznets Curve is not explained by income inequality. In fact, we show that during the sample period inequality has risen monotonically with income, ruling out the traditional Kuznets Curve. Our finding is robust to adding a large set of controls that are used in the literature to explain the incidence of crime, as well as to controlling for state and year fixed effects. The Curve is also revealed in nonparametric specifications. The Crime Kuznets Curve exists for property crime and for some categories of violent crime.

The police interview is one of the most important investigative tools that law enforcement has close at hand, and police interview methods have changed during the twentieth century. A good police interview is conducted in the frame of the law, is governed by the interview goal, and is influenced by facilitating factors that may affect the elicited report. The present doctoral dissertation focuses on police interviews in cases of very serious crimes of violence and sexual offences. Results reveal crime victims’ and perpetrators’ experiences of being interviewed and police officers’ attitudes towards conducting interviews related to traumatizing crimes. Study 1 revealed that when police officers interviewed murderers and sexual offenders, the interviewees perceived attitudes characterized by either dominance or humanity. Police interviews marked by dominance and suspects’ responses of anxiety were mainly associated with a higher proportion of denials, whereas an approach marked by humanity, and responses of being respected were significantly associated with admissions. In line with Study 1, the victims of rape and aggravated assault in Study 2 also revealed the experience of two police interview styles, where an interviewing style marked by dominance and responses of anxiety was significantly associated with crime victims’ omissions of information. Moreover, a humanitarian interviewing style, and crime victims’ feelings of being respected and co-operative, was significantly related to crime victims providing all information from painful events. Special squad police officers’ attitudes towards interviewing crime victims, in Study 3, also showed a humanitarian approach and two dominant approaches, one affective and the other refusing. The attitude towards interviewing suspects of crimes in focus revealed humanitarian and dominant interviewing attitudes, and an approach marked by kindness. The present thesis shows that, during their entire career, an overwhelming majority of the special squad police officers have experienced stressful events during patrol as well as investigative duty. Results show that symptoms from stressful event exposures and coping mechanisms are associated with negative attitudes towards interviewing suspects and supportive attitudes towards crime victim interviews. Thus, experiences from stressful exposures may automatically activate ego-defensive functions that automatically generate dominant attitudes. Moreover, it is important to offer police officers who have been exposed to stressful events the opportunity to work through their experiences, for example, through debriefing procedures. After debriefings, police officers are better prepared to meet crime victims and suspects and, through conscious closed-loop processes, to conduct police interviews without awaking ego-defensive functions.

This paper asks: is it a fact that there is more violence in districts affected by Naxalite (Maoist) activity compared to those which are free of Naxalite activity? And can the existence of Naxalite activity in some districts of India, but not in others, be explained by differences in economic and social conditions? This study identifies districts in India in which there was significant Naxalite activity and correlating the findings with district-level economic, social, and crime indicators. The econometric results show that, after controlling for other variables, Naxalite activity in a district had, if anything, a dampening effect on its level of violent crime and crimes against women. Furthermore, even after controlling for other variables, the probability of a district being Naxalite-affected rose with an increase in its poverty rate and fell with a rise in its literacy rate. So, one prong in an anti-Naxalite strategy would be to address the twin issues of poverty and illiteracy in India.

Homicide-suicides, the murder of one or several individuals followed by the suicide of the perpetrator, are rare but have devastating effects on families and communities. We did a systematic review and meta-analysis of studies comparing perpetrators of homicide-suicides with perpetrators of simple homicides and suicides and examined the proportion of firearm use and its correlation with firearm availability. We searched Medline and Embase from inception to July 2012 and identified 27 eligible studies. Perpetrators of homicide-suicides were older and more likely to be male and married to or separated from their victims than perpetrator of simple homicides or suicides. Influence of alcohol and a history of domestic violence or unemployment were less prevalent in homicide-suicides than in homicides. The proportion of firearm use in homicide-suicides varied across countries and was highest in the USA, Switzerland and South Africa, followed by Australia, Canada, The Netherlands and England and Wales, with a strong correlation between the use of firearms and the level of civilian gun ownership in the country. Our results indicate that homicide-suicides represent a distinct entity, with characteristics distinguishing them both from homicides and suicides.
