This diploma thesis brings theory, current knowledge and empirical analysis. It focuses on the methamphetamine market in the Czech Republic. In its theoretical part it follows individual schools of Economics with focus on the differences in expected behavior of the participants in the illegal market. The research is primarily oriented on finding the effects of the enforced prohibition on users, producers and sellers of pervitin. The main benefit of the diploma is the definition of as yet not published specifics about not only the whole segment, but also the comparison of characteristics of both an open and closed pervitin scene, where surprisingly there exists not only a difference in the quality of the product but also in the approach of sellers to customers. From a comparison with the heroin market one can see a trend of mutual exchanges of pervetin for heroin and also differences in competitive environments. The result of the economic analysis is the filling of gaps in the current understanding and elicitation of conclusions, which are compared to the economical studies and official overviews of the Czech drugs market.

Economical analysis of market with cannabis products is solved by the master thesis. Emphasis is placed on the situation and specifics of Czech Republic market with focus on price of cannabis drugs. It contains research questions which deal with role of price of drugs users -- if price factor is more significant than other socio-economical factors. The thesis describes development of legislation and anti-drug policy in the Czech Republic and its focus on cannabis products. In the theoretical part of the thesis there are presented economical and social aspects of anti-drug policy and its forms of applications in the Czech Republic. Analytical part of the thesis is focused on analysis of recent situation in the market with cannabis products. There is presented survey dedicated to consumption of cannabis drugs by students of high (secondary) schools. The survey also deals with attitudes of these students towards cannabis drugs. The survey is the source of data for regression analysis. Research has shown the most of users of marijuana do not pay for the drug. In case of act of buying there are frequent volume distcounts. Procurations of anti-drug policy which are trying to influence the price therefore may not have any impacts on buying behavior.

The primary argument and area of interest within this explorative study lies within the domain of copyright law enforcement of the creative industries and argues the deleterious impact that the infringement of copyright has on national and individual balance sheets and the opportunity to re-engineer the copyright dividend. Globally, creative industries are estimated to account for more than 7% of the world’s gross domestic product and are predicted to grow, on average, 10% per year. Digitization and the internet have seen to it that copyright, through inter alia the unlimted reproduction capacity of copyrights, brought by digitization and the internet, has seen its importance in the intellectual property bouquet soar. This study endevours to establish the beginning of a discourse on copyright in which the very survival of the creative industries, galvanized, for more than a century by technology and changes in technology and the security of its consumers, depends on the adopting of improved, farsighted, equitable, inclusive and stricter measures in order to protect such from both internal and external threats. From a global perspective most copyright owners and nations with few exceptions rich in copyrights, compounded by the presence of unsubstantial collaboration, suffer losses because the protection of their respective intellectual property rights such as copyright, trademarks and patents are not adequately aligned with what may be referred as the technology conversation. It is imperative that the collaborative copyright alliances develop a strategic agenda that is relevant to the technology conversation in order to re-engineer the copyright dividend where new copyright enforcement mechanisms will be deployed. In as much as this study placed greater emphasis on online infringement, physical piracy is still pervasive and it intensely contributed to the explorative conversation. Piracy effectively relieves copyright authors and the State of the royalty flows that arise from legal and transparent use of copyright. It is these royalty flows that give rise to term “copyright dividend” literally meaning the income arising from the underlying copyright assets. Seeing what is stolen by piracy as the “theft”, whether direct or indirect, of copyright dividends, the challenge to address, avert and amend such outcomes is akin to re-engineering the copyright dividend and this meant the examining of the copyright law structures influencing and regulating the trade in copyrights. In this study the focus was initially on understanding the copyright law regimes and the real challenges that influenced their respective implementations that generated a copyright dividend. Understanding exactly how well such were actually working rested on exploring the lived experiences and perceptions of ten copyright experts across the world from two primary copyright law regimes. Such an exploration was necessary as such provided the requisite insight into inter alia the legal framework wherein both the illegal market and the legal market for copyright operated, to the threats faced the copyright dividend. Five research questions were used in this study. Such served as the discussion points used in the interviews with the ten research participants.These five research questions emerged from the problematization within current , literature and supported by the research data. The obtained data were grouped in relation to the five research questions and filtered to identify commonalities amongst the ten participants. The obtained data were grouped in relation to the five research questions and filtered through a lamination process,which emerged to identify commonalities amongst the ten participants.The global copyright law system and stakeholdership presently lack the necessary strategies, capacities, will and common thought to effectively address infringement. This is the major impediment of technological advancement and thus reengineering the copyright dividend was critical. To a demonstratable extend it is independent of the progress of governments and other relevant parties affected by infringement. The data also showed that infringement is an eroding threat to intellectual property and that critical knowledge is an urgent necessity to re-install the copyright value in its global ecosystem, which is essentially achieved by diverting the copyright dividends stolen by the illegal copyright market and re-engineering the copyright dividend. The outcome is that copyright law enforcement promotes the returns of dividends and fair trade to the rightful owners in an accountable and sustainable manner, as was and is intended by the global copyright law regimes. / PhD (Business Administration), North-West University, Potchefstroom Campus, 2015

Objectifs. L’objectif de ce mémoire est d’améliorer les connaissances quant à l’effet des interventions policières sur la violence imputable aux bandes criminelles. À travers l’évaluation des cinq plus importantes opérations policières réalisées entre 1991 et 2008 au Québec, trois modèles conceptuels sont confrontés : 1) celui du marché qui prévoit une hausse des affrontements entres bandes rivales dont le but est de prendre possession d’un marché criminel maintenant disponible en raison du retrait d’un joueur clé, 2) celui de la dissuasion qui prévoit une baisse des violences criminelles, et 3) celui de l’attrition qui envisage une baisse des violences en raison de l’essoufflement des bandes. Méthodologie. Les données de cette étude proviennent de l’Enquête générale sur les homicides de Statistique Canada. Différents taux d’homicides furent agrégés sur une base annuelle pour différentes provinces et régions métropolitaines de recensement. Des analyses de séries chronologiques interrompues furent ensuite réalisées pour estimer l’effet des interventions policières. Résultats. L’opération Printemps 2001 est la seule intervention policière à être associée à une baisse significative des homicides reliés aux bandes criminelles. « Sans-Frontière », « Colisée » et les deux escouades Carcajou de Montréal et de Québec, n’ont produit aucun effet préventif notable. Au contraire, Carcajou Montréal et Québec ont été associées à une hausse des homicides liés aux gangs. Conclusion. Les présents résultats appuient davantage la thèse de la dissuasion que celles du marché ou de l’attrition. Afin de produire un effet de dissuasion, les résultats suggèrent que l’intervention policière doit : 1) cibler un nombre important de membres de l’organisation criminelle, 2) s’attaquer aux têtes dirigeantes, 3) assurer la neutralisation des membres de l’organisation, et 4) assurer la diffusion du message pénal auprès des délinquants concernés. D’autres études sont toutefois nécessaires pour estimer l’effet des interventions policières dans d’autres contextes. / Objectives. The objective of this dissertation is to further our understanding about the effects of police interventions on gang-related violence. Using the five most importance police strikes conducted in the Province of Quebec between 1991 and 2008, the relevance of three conceptual frameworks is compared: (1) the market thesis that predicts an increase in gang-related violence for the possession of illicit markets, following the withdrawal of a key player, (2) the deterrence/neutralization model that predicts a decrease in gang-related violence, and (3) the attrition model which predicts a gradual decline in violence (due to losses suffered by each party during a conflict). Methodology. Data come from the Homicide Surveys conducted by Statistics Canada. Various homicide rates were aggregated on an annual basis for different Canadian Provinces and metropolitan census areas. Pooled time series analyses were then conducted to estimate effects of police interventions. Results. Operation “Printemps 2001” is the sole police intervention to be associated with a significant decline in gang-related homicides. “Sans-Frontières”, “Colisée”, and both Wolverine squads, launched in the cities of Quebec and Montreal, did not produce any noticeable preventive effect. On the opposite, Wolverine Quebec was associated with an increase in gang-related homicides. Conclusion. The present results rather support the deterrence thesis than the market and attrition models. In order to produce deterrence, police interventions have to: (1) target a significant fraction of the members of the criminal organization, (2) target the leaders, (3) neutralize members of the organization, and (4) make sure that likely sanctions are known by potential offenders. Other studies are, however, required to estimate the impact of police interventions in other settings.

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. / In this study, the spatial and temporal mobility of crime guns in the province of Quebec are examined. This study proposes two new measures to assess the mobility of stolen firearms: time-to-find and distance-to-recovery. These new measures allow an assessment of the impacts of guns that were in illegal circulation in regards of the constitution of the illegal firearms market in the province of Quebec. Descriptive analyzes were first conducted in this study on three segments of the data set obtained from la Banque de données québécoise sur les armes à feu recouvrées : the complete data set, the crime guns and stolen firearms. The spatial and temporal mobility analyzes were only applied to the subgroup of 501 stolen firearms because these guns have more detailed characteristics of their movement before their recovery by judicial authorities. Results show that stolen firearms that have greater mobility in time and space in the province of Quebec are handguns, firearms involved in market crimes, non-registered and non-restricted firearms. However, in order to better understand the dynamics of stolen firearms in the territory, the registration status of a stolen firearm is the most important indicator of the mobility because, to some extent, it determines how these guns will be rooted in the illegal market. The non-registered stolen firearms in this study are in fact more likely to concentrate in the criminal markets, which significantly increase their "lifecycle” and mobility in the province of Quebec.
