Bipartite Network Model for Inferring Hidden Ties in Crime DataIsah, Haruna, Neagu, Daniel, Trundle, Paul R. 08 1900 (has links)
No / Certain crimes are difficult to be committed by individuals but carefully organised by group of associates and affiliates loosely connected to each other with a single or small group of individuals coordinating the overall actions. A common starting point in understanding the structural organisation of criminal groups is to identify the criminals and their associates. Situations arise in many criminal datasets where there is no direct connection among the criminals. In this paper, we investigate ties and community structure in crime data in order to understand the operations of both traditional and cyber criminals, as well as to predict the existence of organised criminal networks. Our contributions are twofold: we propose a bipartite network model for inferring hidden ties between actors who initiated an illegal interaction and objects affected by the interaction, we then validate the method in two case studies on pharmaceutical crime and underground forum data using standard network algorithms for structural and community analysis. The vertex level metrics and community analysis results obtained indicate the significance of our work in understanding the operations and structure of organised criminal networks which were not immediately obvious in the data. Identifying these groups and mapping their relationship to one another is essential in making more effective disruption strategies in the future.

Maskulinitetsgörande i processen att lämna en kriminell gruppering : En kvalitativ intervjustudie / The masculinity in the process of leaving a criminal group : A qualitative interview studyOlsson, Moa, Åhlin, Robyn January 2022 (has links)
I detta kvalitativa arbete undersöktes om och, i sådana fall, på vilket sätt maskulinitetsgörande kunde påverka processen att lämna en kriminell gruppering och den kriminella livsstilen, samt hur arbetet i stödverksamheter förhöll sig till maskulinitetsgörande. Detta undersöktes genom semistrukturerade intervjuer med sju individer från stödverksamheter som hade insyn i arbetet att hjälpa individer att lämna kriminella grupperingar samt insyn i processen att lämna kriminella grupperingar. Arbetet tog utgångspunkt i två maskulinitetsteorier. Den tematiska analysen resulterade i fyra centrala teman, som belyste maskulinitetsgörande i processen att lämna en kriminell gruppering och stödverksamheternas arbete med detta. Dessa var: upprätthålla status, strävan efter att bli en deltagande medborgare med kapital, känslomässig process och en kvinnlig partners roll i processen. Delar av resultatet kunde anses överensstämma med tidigare forskning och resterande resultat berörde viktiga aspekter vilka kan vara av värde att undersöka i framtiden. / This qualitative paper examined whether and, in such cases, in what way masculinity influenced processes of leaving criminal groups and the criminal lifestyle and how the work in the support organizations related to masculinity. This was investigated through semi-structured interviews with seven individuals from support organizations who had insight into the work of helping individuals to leave criminal groups, and insight into the process of leaving criminal groups. The paper was based on two theories about masculinity. The thematic analysis resulted in four central themes, which highlighted masculinity in the process of leaving criminal groups and the supporting work regarding masculinity. These were: maintaining status, striving to become a participating citizen with capital, emotional process and a female partner's role in the process. Parts of the results corresponded with previous research and the remaining results referred to important aspects which may be of value to investigate in the future.

Civilian Agency in Contexts of Organized Criminal Violence : The case of the bandas criminales in ColombiaBlöth, Pauline January 2019 (has links)
While research increasingly recognizes the importance of civilian agency and strategies in influencing conflict dynamics and reducing civilian victimization in the context of armed conflict, research has until now not investigated whether civilians also have the capacity to limit organized criminal violence. This study thus aims to answer under which conditions civilians can protect themselves from and influence levels of organized criminal violence and draws on the literatures on civilian self-protection and autonomy strategies in the context of armed conflict, as well as on organized criminal governance and violence. I argue that civilian communities with high levels of social organization will experience lower levels of violence, as they are more likely to mount successful collective strategies that influence costs and benefits for organized crime groups to use violence. Using the method of structured focused comparison, this hypothesis is tested on the Colombian municipalities San Juan de Arama, Vistahermosa and Granada. The results show some support for the theorized relationship. In general, municipalities with higher levels of social organization experienced lower levels of organized criminal violence, but this relationship appears to be moderated by levels of civil war violence. Due to the explorative character of this study, more research is warranted.

Investigation and prosecution of transnational women trafficking: the case of EthiopiaBeyene, Selam Gebretsion January 2011 (has links)
<p>Human trafficking is a widespread and growing crime in the world. Trafficking by its nature involves movement from one place to another and in most cases, it comprises crossing international borders. Although the estimation of victims of trafficking stretches to 2 450 000, the number of prosecutions is less than 5 000. This indicates the challenges faced by many countries in the investigation and prosecution of trafficking cases. Transnational human trafficking is committed in different places, making investigation and prosecution very complex. This paper examines how investigation and prosecution can be carried out when the criminal acts are committed in different countries. It also examines how the issue of jurisdiction is entertained. Furthermore, it addresses who can be termed as &ldquo / traffickers&rdquo / in dealing with human trafficking issues. Ethiopia is facing a big problem in fighting human trafficking. Like most countries, the issue of human trafficking is closely related to women. Ethiopia uses the criminal justice system as a tool to eradicate women trafficking. The investigation and prosecution of trafficking cases face many problems which have a direct impact on the countryâs efforts to overcome human trafficking. Thus, this research will contribute significantly by highlighting deficits in the criminal justice system as it deals with the investigation and prosecution of women trafficking issues and by making recommendations with regards to them.</p>

Soixante ans de règlements de compte au QuébecJasmin, Guillaume 04 1900 (has links)
Objectifs. Les objectifs de ce mémoire sont au nombre de deux. Le premier objectif est scindé en deux : l’objectif 1A est d’évaluer l’apport et la validité/fiabilité de l’analyse descriptive des règlements de compte amorcée par Cordeau dans sa thèse de doctorat de 1991 puis d’étendre la portée de cette analyse descriptive de part et d’autre des années 1970-1986. Ceci sera fait afin de voir si les règlements de compte de la période de Cordeau diffèrent de notre ensemble; l’objectif 1B est d’évaluer différents taux afin de voir lesquels nous permettent de mieux comprendre les grandes tendances des règlements de compte et leurs vagues. Enfin, le deuxième objectif est d’utiliser l’analyse de réseau afin de confirmer certains points ressortant de l’analyse descriptive des règlements de comptes et d’analyser la structure sociale du règlement de compte au Québec entre 1953 et 2013.
Méthodologie. En faisant appel à Allô Police et plusieurs autres sources médiatiques, nous avons constitué une base de données des règlements de comptes québécois entre de 1953 à 2013. Nos analyses font appel à une approche holistique qui intègre à la fois l’analyse statistique descriptive, les tableaux croisés, l’analyse temporelle et l’analyse de réseau afin de bien cerner la question des règlements de compte.
Résultats. Nos principaux résultats sont au nombre de quatre: 1) les grandes tendances qu’avait trouvées Cordeau entre 1970-1986 s’appliquent pour l’ensemble des règlements de compte de 1953 à 2013. Ainsi, peu de variations importantes ont été observées entre nos règlements de compte et ceux de Cordeau ; 2) les taux alternatifs se basant sur la population carcérale ou criminelle ne permettent pas de mieux comprendre les règlements de compte par rapport à un taux basé sur la population générale. Par contre, les proportions proposées par Morselli et al (2008) amènent une meilleure conception des périodes d’effervescences du milieu; 3) les groupes criminels qui sont plus exposés à la violence sont aussi ceux qui ont le plus recours à la violence et; 4) les indépendants occupent une place importante parmi les victimes de règlements de compte et ont donc une place importante dans le milieu criminel.
Conclusion. Nos résultats font état du besoin d’intégrer différentes approches théoriques et méthodologiques afin de bien cerner la question complexe qu’est le règlement de compte. Avec les avenues de recherches identifiées à la fin de ce mémoire, nous espérons que la relève sera en mesure de mettre à profit les apprentissages de ce mémoire. / Objectives. This thesis has two objectives. The first objective is divided in two: objective 1A is to evaluate and extend the descriptive analysis of account settlement trends started by Cordeau in his doctoral thesis of 1991. This will be done so as to compare his dataset to ours and see if any significant differences emerge; Objective 1B is to look into the construction and use of alternative account settlement rates to see which one allow us to be better capture the dynamics (ebbs and flows, general tendencies) of this particular subset of homicides. Our final objective is to use social network analysis to confirm and highlight certain findings that will come about through the descriptive analysis. The use of social network analysis will also allow us to analyze the social structure of account settlements in Quebec between 1953 and 2013.
Methodology. Using datasets compiled from Allô Police and other media sources, our approach is a holistic one that seeks to incorporate descriptive statistical analysis, cross-tabulation, trend analysis and social network analysis so as to properly frame and study account settlement patterns and trends.
Results. There are four main results in our study: 1) most of the trends found by Cordeau in his account settlement dataset (1970-1986) are also present within our dataset (1953-2013). There are, thus, few important variations between the two datasets; 2) compared to a general population rate, alternative rates based on the prison population or the larger criminal populations do not add to our understanding of the phenomena. However, the use of rates proposed by Morselli et al (2008) do allow for a clearer picture of unusual periods of activity within the criminal milieu; 3) criminal groups that are more exposed to violence tend to be the groups that resort to violence the most; 4) independent operators form a majority of our account settlement victim dataset and this would seem to indicate the importance of their role in organized crime.
Conclusion. Our results illustrate the need for better integration of different methodologies and theories to properly analyze and understand account settlement trends. With the multiple avenues of research identified at the end of this thesis, we hope that future research can make use of theoretical and methodological integration to build a more complete picture of account settlement trends.
