La diversité des ordres juridiques, ainsi que leur multiplication, ont engendré un besoin croissant d'articulation entre eux. Les seuls mécanismes de coordination ne suffisent plus et s'accompagnent désormais de méthodes d'interaction plus active, durant l'instance et à l'issue de l'instance, formant un tout qu'est le phénomène de coopération judiciaire. Derrière l'analyse de la diversité des méthodes de coopération employées dans l'ordre international (commission rogatoire, notification des actes de procès à l'étranger, extradition, exequatur), et dans l'ordre européen mû par le principe de reconnaissance mutuelle (mandat d'arrêt européen, reconnaissance des décisions civiles et pénales, décision d'enquête européenne), l'étude révèle une unité profonde de la notion de coopération. Les critères de celle-ci, analysée comme un acte de procès, accompli librement par un ordre juridique, à la demande d'un autre, pour les besoins d'une procédure relevant de l'ordre juridique requérant, permettent de remonter à son essence. Elle est un processus d'aide réciproque, fondé sur la réciprocité et dont la finalité de résolution d'un litige transfrontalier dicte les offices respectifs des juges requérant et requis. / The diversity of legal orders and their multiplication have led to a growing need to articulate them. Mechanisms of coordination are no longer sufficient and are complemented by more active methods of interaction both during proceedings in court and upon their completion, thus forming an integral whole, known as the phenomenon of judicial cooperation. Behind the analysis of the diversity of the methods of cooperation that are implemented in the international order (letters rogatory, service of process, extradition, exequatur) and in the European order by virtue of the principle of mutual recognition (European arrest warrant, recognition of civil and criminal judgments, European investigation order), the thesis reveals a prefound unity of the notion of judicial cooperation. Its criteria, analysed as procedural act, free/y accomplished by one legal order upon the request of another, for the needs of judicial proceedings pending before or ended in the requesting legal order, allow to trace the essence of judicial cooperation. At the core of judicial cooperation lies the process of mutual aid, based on reciprocity for the purposes of resolving a transborder litigation, and which defines respective powers of the requesting and the requested judge.

Esta pesquisa aborda a atuação do 4° BPAF – Batalhão de Polícia de Área de Fronteira da Brigada Militar no policiamento na Fronteira Noroeste do RS, frente aos crimes transfronteiriços e transnacionais praticados pelas redes de criminosos. A Brigada Militar não possui atribuição legal para atuar frente aos crimes transnacionais que demandam o trabalho de inteligência, envolvendo investigações de redes criminosas internacionais que ultrapassam a linha de fronteira. Na prática, devido a limitações e à falta de efetivo dos Órgãos Federais de segurança na fronteira, a Brigada Militar vem atuando contra estes tipos de crimes. E casos específicos quando o crime é de cunho transnacional o 4° Batalhão de Polícia de Área de Fronteira da Brigada Militar atende pedidos da Polícia Federal e Receita Federal, realizando operações ao longo da Fronteira Noroeste com prisões de contrabandistas, traficantes de drogas e abigeatários. O policiamento do 4°BPAF da Brigada Militar evoluiu ao longo dos anos, passando de simples patrulhas rurais para patrulhas operacionais especializadas em Fronteira. Com a atuação dos criminosos na região da fronteira em crimes transfronteiriços que se tornaram corriqueiros, o comando do 4°BPAF criou o POE- Pelotão de Operações Especiais para atuar nas patrulhas na fronteira. A partir de 2012 o Governo Federal lança o PEF-Plano Estratégico de Fronteira e a ENAFRON- Estratégia Nacional de Fronteira investindo em viaturas, equipamentos, formação e treinamento de recursos humanos para as Organizações Policiais Militares dos estados da federação na Faixa de Fronteira O estado do Rio Grande do Sul aderiu a esse programa da ENAFRON e não demorou muito para o Alto Comando e o Estado Maior da Brigada Militar elaborarem a Diretriz Geral de Segurança Pública em Área de Fronteira N°26/2012 que foi atualizada pela Diretriz de Policiamento em Áreas de Fronteiras N°034/2015. Também ocorreu nesta época um incremento na realização de operações conjuntas da Brigada Militar, tanto com órgãos Federais de segurança pública e com Exército Brasileiro, como em operações Simultâneas Internacionais com a Polícia de Misiones e a Gendarmeria Nacional Argentina, estreitando assim os laços entre as polícias da Argentina e a Brigada Militar. Este trabalho aborda as técnicas de investigação usadas pelo 4° BPAF da Brigada Militar em sua Atividade de Inteligência e modus operandi no combate aos criminosos na Fronteira Noroeste do Rio Grande do Sul. O 4° BPAF tem um papel muito importante na fronteira em relação ao combate a criminalidade, pois realiza um trabalho que vem ajudando a diminuir a criminalidade da sociedade não só a local, mas também contribui para diminuir os índices de violência ligado ao tráfico de drogas, roubos de veículos nos grandes centros urbanos do estado do Rio Grande do Sul. / This research deals with the performance of the 4th BPAF - Border Brigade Military Battalion of the Military Brigade in the policing in the Northwest Frontier of RS against transboundary and transnational crimes practiced by criminal networks. The Military Brigade has no legal authority to act in the face of transnational crimes, which requires the work of intelligence, involving investigations of international criminal networks that cross the border line. In practice, due to limitations and lack of workers of the Federal Border Security Bodies, the Military Brigade has been acting against these types of crimes. Moreover, specific cases when the crime is transnational in nature, the 4th Border Brigade Battalion of the Military Brigade responds to requests from the Federal Police and the Federal Revenue, conducting operations along the Northwest Frontier with arrests of smugglers, drug traffickers and cattle thieves. The policing of the 4th BPAF of the Military Brigade has evolved over the years, going from simple rural patrols to specialized operational patrols on the border. As cross-border crimes became commonplace, the 4th BPAF command created the POE-Special Operations Squadron to operate on border patrols. Starting in 2012, the Federal Government launches the Border Strategic Plan (PEF) and ENAFRON - National Border Strategy investing in vehicles, equipment, and human resources training for the Military Police Organizations of the states of the federation in the border fringe. The state of Rio Grande do Sul adhered to the ENAFRON program and it did not take long for the High Command and the General Staff of the Military Brigade to elaborate the General Directive of Public Security in Border Area N ° 26/2012 updated by the Police Directive in Border Areas N ° 034/2015. At the same time, there was an increase of joint operations of the Military Brigade, both with Federal public security organs and with the Brazilian Army, as well as in simultaneous international operations with the Misiones Police and the Argentine National Gendarmerie, thus strengthening the ties between the Argentine police and the Military Brigade. This work addresses the investigation techniques of the 4th BPAF of the Military Brigade in its Intelligence Activity and modus operandi in the fight against criminals in the Northwest Frontier of Rio Grande do Sul. The 4th BPAF has a very important role in the frontier in relation to combat crime, since it carries out work that has helped to reduce the society criminality, not only local crime, but also contributes to reduce the rates of violence related to drug trafficking, theft of vehicles in large urban centers in the state of Rio Grande do Sul.

Mobility, as the ability among newcomers and citizens to move temporarily and circularly across international borders and between states, has become a pervasive norm for a significant portion of Canada’s population. Despite its pervasive nature and the growing public interest, however, current research has been limited in how Canadian policies are reacting to the ability of citizens and newcomers to move. This thesis seeks to fill that gap by analyzing Canada’s treatment of mobility within and across policies of immigration, citizenship and foreign affairs. An analytical mobility framework is developed to incorporate interdisciplinary work on human migration and these policy domains. Using this framework, an examination of policy developments in each domain in the last decade reveals that they diverge in isolation and from a whole-of-government perspective around the treatment of mobility. In some instances policy accommodates or even embraces mobility, and in others it restricts it.

Cette thèse a pour objectif de définir un nouveau concept : celui de Territoire Transfrontalier Maritime (TTM) qui se différencie du concept de territoire transfrontalier terrestre par la présence de la mer qui modifie la dialectique ouverture/fermeture propre à ces territoires, du concept de territoire « inter-côtier » puisque la dialectique frontalière vient se superposer à la distance instaurée par la mer et des concepts de méditerranée dans la mesure où les territoires transfrontaliers maritimes se définissent par leur proximité à la frontière alors que les méditerranées comprennent des espaces distants de plusieurs milliers de kilomètres de la frontière.Pour y parvenir, la première partie de la thèse se décompose en trois chapitres. Le premier mène une réflexion autour de la territorialisation de la mer puisque les TTM sont centrés tant géographiquement qu’humainement sur la mer. Or si cette mer s’apparente à un no man’s land il semble inconcevable de parler de TTM. Le second chapitre revient sur la définition de ce concept et les questions qu’il soulève. Une réflexion autour de l’association des termes « mer et proximité » y est conduite : la mer éloigne-t-elle ou rapproche-t-elle les populations riveraines ? Enfin le troisième chapitre présente l’espace transmanche, retenu car il permet de produire des données empiriques inédites tout en testant les hypothèses. Il dévoile aussi le protocole méthodologique élaboré pour l’analyse des TTM, inspiré de la FSS de Di Méo et adapté aux spécificités de ces territoires. La seconde partie expose les résultats obtenus dans le cadre du terrain tout en conservant une démarche comparative afin de bien différencier conceptuellement les TTM des concepts cités précédemment. Le quatrième chapitre est en lien avec les pratiques de l’espace : Observe-t-on des spécificités dans ces pratiques ? La proximité les explique-t-elle ? En quoi les motifs de ces flux contribuent-ils à la territorialisation de l’espace ? Le cinquième chapitre analyse les représentations de l’espace puisque la thèse se positionne dans le champ de la géographie sociale et culturelle. Nous questionnons l’altérité des résidents transmanche : les résidents français et anglais de cet espace ont-ils des visions communes d’un espace partagé ? Enfin le dernier chapitre est dédié à l’institutionnalisation de l’espace. En effet les TTM n’ayant pas d’existence politico-administrative il est nécessaire que leurs acteurs coopèrent et partagent une vision commune de l’espace. Ainsi les concepts de coopération transfrontalière et de gouvernance transfrontalière maritime sont mobilisés. Une étude particulière est menée autour des jumelages transfrontaliers et des relations qu’ils entretiennent avec la territorialisation des espaces. Tout au long de notre travail, l’étude des interactions entre la matérialité, l’immatérialité et l’institutionnalisation de l’espace est au centre de la réflexion. Le questionnement général de la thèse intègre aussi l’incidence de la maritimité sur la constitution d’un TTM. Enfin en raison de notre territoire d’étude il est important de réfléchir sur le concept d’insularité. / This PHD has for objective to define a new concept: that of The maritime Cross-border Territory (MCBT) who differs from the concept of ground cross-border territory by the presence of the sea which modifies the dialectic opening/closure appropriate to these territories, the concept of "inter-coastal" territory because the border dialectic comes to overlap at the distance established by the sea and the concepts of Mediterranean as far as the maritime cross-border territories define themselves by their closeness on the border while the Mediterranean include distant spaces of more than thousands of kilometers of the border.To reach there the first part of the PHD decomposes into three chapters. The first one is dedicated to a reflection around the territorialisation of the sea because the MCBT is centered so geographically as humanely on the sea. Yet if this sea is similar to a no-man's-land it seems inconceivable to speak about MCBT. The second chapter returns to the definition of this concept and the questions which it lifts. A reflection around the association of the terms "sea and closeness" is led there : does the sea take away or does it move closer to the waterside populations? Finally the third chapter presents the cross-Channel, reserved space because it allows to produce new empirical data while testing the hypotheses. It also reveals the methodological protocol developed for the analysis of the MCBT, inspired by DI MÉO'S FSS and adapted to the specificities of these territories.The second part exposes the results obtained within the framework of the ground while keeping a comparative approach to differentiate well conceptually the MCBT of the concepts quoted previously. The fourth chapter is in connection with the practices of the space: observe Tone of specificities in these practices? Does closeness explains them? In what the motives for these flows contribute to the territorialisation of the space. The fifth chapter analyzes the representations of the space because the PHD positions itself in the field of the social and cultural geography. We question the otherness of the cross-Channel residents: have the French and English residents of this space seen in common a shared space? Finally the last chapter is dedicated to the institutionalization of the space. Indeed, the MCBT having no politico-administrative existence it is necessary that their actors cooperate and share a common vision of the space. So the concepts of cross-border cooperation and maritime cross-border governance were mobilized. A particular study was led around the cross-border twinnings and the relations which they maintain with the territorialisation of spaces.Throughout our work, the study of the interactions between the materiality, the immateriality and the institutionalization of the space was in the center of the reflection. The general questioning of the PHD also integrates the incidence of the maritimity on the constitution of a MCBT. Finally because of our territory of study it is important to think about the concept of insularity

Thesis (MA)--Stellenbosch University, 2000. / ENGLISH ABSTRACT: In this era of globalisation, the world is becoming more economically, politically and ecologically interdependent, that is, there is a growing mutual vulnerability between actors. The conditions of growing interdependence produce specific challenging circumstances for the achievement of particular goals, -includinq that of sustainable development. The Southern African context holds further obstacles to such development, which include poverty, inequality, a history of racial conflict and colonialism, and a regional economy on the semi-periphery of the global economy. It is my assertion that it is in the mutual self-interest of states and other stakeholders (e.g. communities) to approach this dilemma through transnational co-operation under the ethical umbrella of sustainable development. Thus this thesis seeks to discover to what extent the construction of Transborder Conservation Areas (TBCAs), relatively large areas which straddle the borders between two or more countries and cover natural systems incorporating one or more protected areas, can meet the criteria of sustainable development, given these conditions. The three primary criteria used for measuring sustainable development are community-based development; close linkages between the environment and development; and co-operation on all levels. The Kgalagadi TBCA, formally recognised on the 7th of April 1999 between South Africa and Botswana, serves as the case study. The conceptual framework used for the analysis is a theory of cooperation, as it applies to the field of International Relations. The key concepts employed here are those of interdependence, co-operation, sustainable development and institutionalisation. The research centers around three key issues: If sustainable development is the way forward for Southern Africa, do TBCAs reflect and fulfill the criteria as set forth by sustainable development? What does the experience of TBCAs in Southern Africa tell us about co-operation, recognising that TBCAs can only succeed if it has a sound base in the awareness and engagement of people? And, how best can decision-makers go about establishing TBCAs? Ultimately the thesis is a call to Southern African countries to embrace this new form of utilising the environment. / AFRIKAANSE OPSOMMING: In hierdie era van globalisering is die wêreld besig om ekonomies, polities en ekologies meer interafhanklik te word, met ander woorde, daar is 'n toenemende wedersydse kwesbaarheid tussen akteurs. Toenemende interafhanklikheid produseer spesifieke uitdagings ten opsigte van die bereiking van sekere doelwitte, insluitend volgehoue ontwikkeling. Daar is besondere hindernisse op die weg na volgehoue ontwikkeling in Suidelike Afrika, is byvoorbeeld armoede, ongelykheid, en verlede gekenmerk deur rassekonflik en kolonialisme, asook en regionale ekonomie op die semi-periferie van die globale ekonomie. Dit is in die wedersydse belang van state en ander betrokke partye (bv. gemeenskappe) om hierdie dilemma te benader deur middel van transnasionale samewerking onder die etiese sambreel van volgehoue ontwikkeling. Hierdie tesis probeer vasstel tot watter mate die skep van Transnasionale Bewaringsgbiede, of sogenaamde "Vredesparke" (Transborder Conservation Areas = TBCAs), d.w.s. relatiewe groot areas aan weerskante van die grens(-e) tussen twee of meer lance en wat natuurlike stelsels dek wat ten minste een beskermde gebied inkorporeer, kan voldoen aan die kriteria vir volgehoue ontwikkeling, gegewe die bogenoemde konteks. Die drie primêre kriteria wat gebruik word om volgehoue ontwikkeling te meet is gemeenskapsgebaseerde ontwikkeling; die hegtheid van die verhouding tussen die omgewing en ontwikkeling; en samewerking op alle vlakke. Die Kgalagadi TBCA, amptelik op 7 April 1999 tussen Suid-Afrika en Botswana erken, dien as die gevallestudie. Die konseptueie raamwerk wat gebruik word in die analise is 'n teorie van samewerking, soos dit van toepassing is op die veld van Internasionale Betrekkinge. Die sleutelkonsepte wat gebruik word is interafhanklikheid, samewerking, volgehoue ontwikkeling en institusionalisering. Die navorsing sentreer rondom drie sleutelkwessies: lndien volgehoue ontwikkeling die weg vorentoe vir Suidelike Afrika is, weerspiëel en voldoen TBCAs aan die vereistes van volgehoue ontwikkeling? Wat kan ons wys raak oor samewerking na aanleiding van ons ervaring van TBCAs in Suidelike Afrika, gegewe dat TBCAs slegs kan slaag indien dit gefundeer is op gemeenskapsbewustheid- en deelname? Laastens, wat is die beste manier waarvolgens besluitnemers TBCAs kan vestig? Ten slotte is hierdie studie 'n beroep op die besluitnemers In Suidelike Afrika om hierdie nuwe wyse waarop die omgewing benut kan word, te ondersteun.

Drivers of environmental change in one location can have profound effects on ecosystem services and human well-being in distant locations, often across international borders. The telecoupling provides a conceptual framework for describing these interactions-for example, locations can be defined as sending areas (sources of flows of ecosystem services, energy, or information) or receiving areas (recipients of flows). However, the ability to quantify feedbacks between ecosystem change in one area and societal benefits in other areas requires analytical approaches. We use spatial subsidies-an approach developed to measure the degree to which a migratory species' ability to provide services in one location depends on habitat in another location-as an example of how telecoupling can be operationalized. Using the cotton pest control and ecotourism services of Mexican free-tailed bats as an example, we determined that of the 16 states in the United States and Mexico where the species resides, three states (Texas, New Mexico, and Colorado) are receiving areas, while the rest of the states are sending areas. In addition, the magnitude of spatial subsidy can be used as an indicator of the degree to which different locations are telecoupled to other locations. In this example, the Mexican free-tailed bat ecosystem services to cotton production and ecotourism in Texas and New Mexico are heavily dependent on winter habitat in four states in central and southern Mexico. In sum, spatial subsidies can be used to operationalize the telecoupling conceptual framework by identifying sending and receiving areas, and by indicating the degree to which locations are telecoupled to other locations.

Thesis (MA (Political Science. International Studies))--University of Stellenbosch, 2009. / ENGLISH ABSTRACT: In an otherwise broad literature on civil conflict little attention has so far been paid to actual conflict violence and variation in severity. Existing work is also hampered by a reliance on a ‘closed polity’ model of the state, leading to disregard of the transnational dimensions of internal conflict, and by a dependence on over‐aggregated data. The present inquiry expands on the existing explanatory framework for variation in civil conflict severity by including transnational factors and characteristics of sub‐national actors. Data on conflict battle deaths are combined with recently available data on transnational ethnic linkages, transnational support and neighbouring conflict as well as other actor and country characteristics. Results from ordinary least squares regression analysis indicate that support for rebel groups from external non‐state actors increase conflict severity, while rebel presence in other states is associated with less severe conflicts. In addition, severity increases with duration but with a diminishing marginal return. Internal armed conflicts are less severe in democratic and ethnically polarised countries but rebel territorial control increases the level of violence. / AFRIKAANSE OPSOMMING: In die andersins omvangryke literatuur oor burgerlike konflik is daar tot op hede min aandag geskenk aan werklike konflikgeweld en variasie in felheid (vernietigende omvang). Bestaande werk word ook belemmer omdat dit staat maak op ’n model van die staat as ‘geslote regering’, wat lei tot verontagsaming van die transnasionale dimensies van interne konflik, en staat maak op oor‐geaggregeerde data. Hierdie ondersoek brei uit op die bestaande verklarende raamwerk vir variasie in felheid van burgerlike konflik deur transnasionale faktore en eienskappe van subnasionale deelnemers in te sluit. Data oor konflikgevegsterftes is gekombineer met onlangse data oor transnasionale etniese koppelings, transnasionale steun en naburige konflik, sowel as ander deelnemer‐ en landeienskappe. Resultate van gewone kleinstekwadrate‐regressie‐analise dui daarop dat steun aan rebellegroepe deur eksterne nie‐staatsdeelnemers konflikfelheid laat toeneem, terwyl rebelleteenwoordigheid in ander lande geassosieer word met minder fel konflikte. Felheid neem ook toe saam met duur maar met ’n afnemende marginale opbrengs. Interne gewapende konflikte is minder fel in demokratiese en etnies gepolariseerde lande, maar rebellebeheer oor grondgebied verhoog die vlak van geweld.

Marquées par une histoire conflictuelle, les frontières de la Pologne ont connu depuis 1990 d’importants changements relatifs à leurs fonctions. Cette thèse se propose d’analyser les conséquences géopolitiques de ces changements sur les espaces frontaliers ainsi que sur le territoire polonais, au cours de l’intégration de la Pologne à l’Union européenne (UE), du début du processus d’adhésion à l’UE en 1998, à l’entrée complète dans l’espace Schengen en 2008. Ce travail revient dans un premier temps sur la dimension historique des frontières de la Pologne, caractérisées dans leur ensemble parleur grande instabilité. Ce retour en arrière nous permet de nous interroger, a posteriori, sur la spécificité des faits historiques qui ont marqué de façon durable l’espace polonais et ses frontières. Il propose ensuite une analyse comparative qui s’articule autour de la distinction typologique concernant le statut actuel des frontières polonaises : d’un côté les dyades internes de l’UE, frontières « en déconstruction » ; de l’autre les frontières « en reconstruction » sur les nouveaux confins de l’UE. Il tente enfin de faire la synthèse de ce « jeu des frontières » en analysant ses conséquences sur le territoire polonais. / Marked by a history of conflicts, the borders of Poland have experienced significant changes in their functions since 1990. This thesis aims to analyze the geopolitical consequences of these changes on the border area and the Polish territory, throughout the integration of Poland into the European Union (EU), from the beginning of the accession process in 1998, to its full membership in the Schengen area in 2008. At first, this work deals with the historic dimension of the borders of Poland, characterized by their high instability. This particularity allows us to retrospectively examine, the specificity of thehistorical facts that have durably affected the Polish space and its borders. Then this thesis provides a comparative and multiscalar analysis which revolves around the typological distinction regarding the status of Polish borders: the internal,« deconstructing » EU borders on one side, the new external « reconstructing » EU borders on the other. Finally, this work tries to analyze the effects of this « borders’ game » on the polish territory.

L’intérêt d’une étude portant sur les espaces périphériques européens découle des transformations qui affectent les frontières depuis les années 1980 : alors que l’intensification de flux transnationaux de différentes natures semble les ignorer, la disparition des marques physiques les symbolisant tend à les invisibiliser, et la promotion de politique de coopération au niveau communautaire, à les dépasser. Parmi les zones frontalières, celles qui partagent une histoire commune offre un véritable intérêt heuristique : l’analyse de l’évolution des rapports sociaux, économiques, politiques et institutionnels qu’entretiennent les sociétés frontalières se double d’une interrogation sur la permanence de liens identitaires par-delà la frontière. Dans le département des Pyrénées-Orientales, l’attrait pour la Catalogne se traduit, depuis le début des années 2000, par deux phénomènes concomitants : tandis que les projets de coopération se sont multipliés et diversifiés, des acteurs politiques et sociaux ont entrepris de revivifier le sentiment d’appartenance à la localité. L’étude tend à montrer que l’intensification des interactions n’a pas abouti à l’avènement d’un espace transfrontalier intégré et que les actions identitaires ne semblent pas redessiner le circuit des allégeances territoriales. Tout se passe comme si, au rebours de l’idée préconçue d’une Europe « sans frontières », les limites territoriales jouaient toujours un rôle dans la structuration des représentations et l’orientation des conduites. / The interest of a survey about european surrounding spaces follows from the transformations affecting the borders since the 1980’s : even if the transnational movements of different natures seem to take no heed of them, even if there’s a tendency to turn their physical marks invisible, and even if the political promotion of cooperation at a community level tend to overcome them. Among the border belts, those having a common history afford a real heuristic interest ; the analysis of the economical, political and institutional relation development as well as social relations maintained by border belts couples with an interrogation about the continuity of identity links over the border. Since the beginning of the 2000’s, in the Pyrénées-Orientales departement, the appeal for Catalogne has been resulting by two concomitant phenomenoms : whereas cooperation plans have increased and diversified,political and social protagonists have undertaken to revive the feeling of belonging to the local place. The survey tends to show that the interaction intensification hasn’t resulted in an integrated cross-border space advent and that identity actions don’t seem to change the territorial allegiance channel. Everything is going as if, counter to the preconceived idea of a “no border” Europe, the territorial limits were still playing an important part in the representation structures and management tendency.
