This thesis is an examination of why South Africans have converted to Buddhism, how this conversion has come about and what the meaning of the conversion has been in their lives. Chapter one is a literature review which revealed very little literature available on conversion to Buddhism and less on the conversion of South Africans to Buddhism. L.R. Rambo's Theory of Conversion is used in this thesis to see if these conversions to Buddhism can be understood within this theory. In Chapter two Rambo's theory, which is a holistic model for conversion, is analyzed in detail. He proposes seven stages within his model: crisis, quest, encounter, interaction, commitment and consequences. Context is Rambo's first stage and in Chapter three the socio-historic and religious background of these converts is examined. In order to understand how and why these conversions have come about there needs to be an understanding of the background from which these converts come. Taking Refuge (or the Gohonzon Ceremony) was used for the purpose of this thesis to be the turning point from non-Buddhist to Buddhists. In Chapter four the meaning and importance of Taking Refuge is discussed. The empirical aspect of this thesis was to interview twenty South Africans who had converted to Buddhism. Chapter five is a detailed analysis of these interviews and Appendix two gives the questionnaire used. The aim of this analysis was firstly, to investigate whether these conversions to Buddhism can be understood in the context of Rambo's theory, secondly, to see whether Taking Refuge is the correct choice of the turning point from non-Buddhist to Buddhist. In the conclusion it was found that Rambo's theory did not fully account for the conversion of the interviewees to Buddhism, and that Taking Refuge was not necessarily a good focal point in the conversion process. In the light of this a Developmental theory of becoming a Buddhist was proposed which has the following steps: Context, exposure, interest invoked, practical application, commitment and consequences. From the analysis of the people interviewed their conversion to Buddhism was a developmental process rather than a conversion as such. Hence their conversion fitted more closely with a Developmental theory than with Rambo's theory of conversion. This ties in with the discovery amongst the interviewees that none of them experienced one focal point at which they became Buddhist. For most of the interviewees becoming a Buddhist was a developmental process, with many of them having some sort of proto-Buddhist tendency within them before ever hearing about Buddhism. / RELIGIOUS STUDIES & ARABIC / DLITT ET PHIL (REL STUD)

La thèse est composée de trois parties. La première présente un certain nombre de mesures de dépendance extrême. Une application sur les actions et les obligations de 49 pays montre que la théorie des valeurs extrêmes multivariées conduit aux résultats différents de ceux issus du coefficient de corrélation, mais relativement proches de ceux obtenus du rho de Spearman conditionnel multivarié. Cette partie évalue aussi le risque de pertes importantes simultanées. La deuxième partie examine les déterminants des co-mouvements extrêmes entre 5 pays core et 49 pays non core. Les mécanismes de transmission des chocs varient de la période moins récente à la période récente, des pays développés aux pays émergents, des chocs normaux aux chocs extrêmes. La troisième partie étudie le rôle de valeur refuge de l’or sur la période 1986-2012. Les gains positifs extrêmes de l'or peuvent être liés aux pertes extrêmes du S&P. Cependant, ce lien n'est pas toujours valable, il évolue dans le temps et serait conditionné par d'autres facteurs. / The thesis consists of three parts. The first part introduces a number of measures of extreme dependency. An application on stock and bond markets of 49 countries shows the multivariate extreme value theory leads to results which are different from those from the correlation coefficient, but relatively close to those obtained from multivariate conditional Spearman's rho. This part also assesses the risk of simultaneous losses. The second part examines the determinants of extreme co-movements between 5 core countries and 49 non-core countries. Transmission mechanisms of shocks vary from less recent to recent period, from developed to emerging markets, from normal to extreme shocks. The third part examines the role of safe haven of gold over the period 1986-2012. Extreme positive gains of gold can be linked to extreme losses of S&P. However, this relationship is not always valid, it evolves over time and could be determined by other factors.

Chez les parasites à cycle complexe et à transmission trophique, des stratégies d’exploitation de l’hôte intermédiaire ont été sélectionnées. Notamment, de nombreux parasites sont capables d’altérer le comportement de leur hôte intermédiaire (manipulation comportementale). Cette manipulation n’intervient que lorsque le stade larvaire du parasite est infectieux pour l’hôte définitif. Avant d’atteindre cette infectivité, le développement du stade larvaire n’est pas suffisamment avancé pour lui permettre de s’établir dans l’hôte définitif (il est dit non-infectieux). La transmission prématurée d’un stade non-infectieux implique alors la mort du parasite. Les parasites capables de renforcer les défenses anti-prédateurs de leur hôte intermédiaire au stade non-infectieux (i.e. de le protéger vis-à-vis de la prédation), avant de manipuler leur comportement au stade infectieux (i.e. de les exposer à la prédation par l’hôte définitif) devraient avoir été sélectionnés. Dans ces travaux de thèse, j’ai pu montrer qu’au stade larvaire non-infectieux, le parasite acanthocéphale Pomphorhynchus laevis renforce les défenses anti-prédateurs de son hôte intermédiaire amphipode, ce qui a pour effet de diminuer ses risques de prédation. Cet effet protecteur de l’hôte intermédiaire affecte négativement l’approvisionnement de l’amphipode, bien que cela n’ait aucune incidence sur l’état des réserves énergétiques de l’hôte. De même, le comportement reproducteur de l’hôte mâle n’est pas affecté par l’infection par ce stade protecteur. Les origines de cette stratégie parasitaire sont discutées, et des perspectives écologiques à ce changement comportemental de l’hôte sont suggérées / In trophically-transmitted parasites, exploitation strategies of the intermediate host have been selected, in a way increasing parasites transmission probabilities to their definitive host. Particularly, numerous parasites are able to alter their intermediate host behaviour, a phenomenon called ‘behavioural manipulation’. This manipulation only occurs when the parasite developmental stage (or larval stage) is infective for the definitive host. Before reaching this stage, the development of parasite larvae is not sufficiently advanced to allow establishment in the definitive host (this stage is thus called ‘non-infective’). Early transmission of a non-infective stage therefore implies parasite death. Parasites able to reinforce their intermediate host anti-predatory defences when non-infective (i.e. protecting them from predation), before manipulating their intermediate host behaviour when infective (i.e. exposing them to predation by definitive hosts), should have been selected. In this thesis, I showed that, when non-infective, the acanthocephalan parasite Pomphorhynchus laevis strengthens its amphipod intermediate host anti-predatory defences, which diminishes its host predation risk. This protective-like strategy negatively affects the amphipod food intake, although it has no effect on host energetic reserves. Similarly, the male amphipod reproductive behaviour is not affected by infection with a non-infective stage of the parasite. The origins of such parasitic strategy are discussed, and ecological perspectives to this host behavioural change are suggested

This research is associated to the FAPESP 2011/0095-7 thematic project, \"Interdisciplinary palaeoenviromental studies at Espirito Santo coast\" and to the FAPESP Research Program about Climate Global Change (PFPMCG-FAPESP). The objectives were: (1) to characterize the late Pleistocene connection between Atlantic and Amazon rainforest and possible routes of interaction (coast, continent or both); (2) to identify environmental characteristics that indicates the Northeastern Espírito Santo and Southern Bahia as a stable forest since the late Pleistocene; (3) reconstitute the vegetation dynamics and infer climate fluctuations. Three sedimentary cores were collected: at northern Espirito Santo (ES) state, southern Bahia (BA) and eastern Minas Gerais (MG). Carbon and nitrogen isotope analyses and bioindicators in sediments/ soils, chronologically determined by radiocarbon dating, contributed to the local palaeoenvironmental reconstitution. At ES, from ~33,460 to ~13,740 cal yr BP the vegetation was composed of arboreal/ shrub cold adapted species and the organic matter recorded the dominance of C3 plants (?13C ~-28?), suggesting a cold and humid forest domain. From ~13,740 to ~9500 cal yr BP vegetation changes, with the increase of grasses and decrease of arboreal types. Between ~9500 and to ~4000 cal yr BP herbs were abundant with a probable mixture of C3 and C4 plants (?13C ~-24?) and algae, suggesting a higher seasonality between humid and dry season. From ~7300 cal yr BP until present the peat layer initiates its deposition, and the pollen records represents the current vegetation. At BA, radiocarbon dating in high-resolution, C and N isotopes and palynology each ~150 years from ~6400 to ~3400 cal yr BP showed detailed vegetational dynamics. From ~6400 to ~5620 cal yr BP the pollen record indicates abundance of trees and shrubs (up to 96%). From ~5620 to ~4850 cal yr BP occurred a slightly increase of herbs (28%) but the ?13C of ~-28% indicate C3 plants domain. From 4850 to ~3400 cal yr BP trees and shrubs abundance increases up to 94%, indicating the forest domain. The results confirm the forest stability and high local humidity, allowing to recognize the area as a probable refugee since 6500 cal yr BP. Vegetation, climate and the landscape has changed at MG since ~10,000 cal yr BP. From 10,600 to ~9500 cal yr BP, pollen was not preserved, C/N values (2 to 11) reveal the algal contribution, the ?13C (~-20?) indicate the mixture of C3 and C4 plants and radiocarbon date inversions indicate that the material was reworked. From 9,500 to 7,500 cal yr BP the vegetation was predominantly herbaceous with mixture of C3 and C4 plant sources (?13C ~-17?). From 7,500 to 7,000 cal yr BP C3 plants (?13C ~-30?) as trees/shrubs domains the polen record. From ~7,000 to ~6500 cal yr BP the pollen records the herbaceous abundance, dominated by C4 plants (?13C ~-12 to 18?). Peat deposition starts at ~6500 cal yr BP composed by C3 plants, mainly dominated by trees. Pollen records since at least early Holocene and the floristics of current vegetation did not show any disjunct specie with Amazon / Este projeto está associado ao temático FAPESP 2011/00995-7, \"Estudos paleoambientais interdisciplinares na costa do Espírito Santo\", e ao Programa FAPESP de Pesquisas sobre Mudanças Climáticas Globais (PFPMCG-FAPESP). Os objetivos foram: (1) caracterizar a conexão da Mata Atlântica e Floresta Amazônica e possíveis rotas de interação (litorânea, continental ou ambas); (2) identificar padrões que caracterizem a região da costa norte do Espírito Santo e sul da Bahia como refúgios florestais; (3) reconstituir a dinâmica da vegetação e inferir flutuações climáticas desde o Pleistoceno tardio. Três testemunhos sedimentares foram coletados: ao norte do Espírito Santo (ES), ao sul da Bahia (BA) e ao leste de Minas Gerais (MG). Análises isotópicas de carbono e nitrogênio e bioindicadores em sedimento/solos, cronologicamente determinados por datação 14C, contribuíram para a reconstituição paleoambiental nestas regiões. No ES, de ~33.460 a ~13.740 anos cal AP, a vegetação era composta por espécies de árvores/arbustos típicas de regiões frias com o domínio de plantas C3 (?13C ~-28?), sugerindo a presença de uma floresta fria e úmida. De ~13.740 a ~9500 anos cal AP ocorreu o aumento das herbáceas e diminuição dos tipos arbóreos. Entre ~9500 e ~4000 anos cal AP, as herbáceas tornaram-se abundantes com mistura de plantas C3 e C4 (?13C~-24?) e algas, sugerindo maior sazonalidade entre as estações seca e úmida. De ~7300 anos cal AP até o presente, iniciou-se a deposição da turfa e pólen da vegetação atual. Na BA, a alta resolução de datação C-14, isótopos de C e N e palinologia a cada ~150 anos entre ~6400 e ~3400 anos cal AP revelaram a dinâmica da vegetação. Entre 6400 e 5620 anos cal AP arbóreas/arbustivas (96%) são abundantes. De ~5620 até ~4850 anos cal AP ocorreu um pequeno aumento de herbáceas (28%), e os valores de ?13C ~-28% indicam o domínio de plantas C3. De 4850 a ~3400 anos cal AP, a abundância de arbóreas/arbustivas (94%), indica domínio florestal. Os resultados confirmam a estabilidade florestal e a umidade local, permitindo reconhecer esta área como um possível refúgio florestal desde pelo menos 6500 anos cal AP. Em MG, desde ~10.000 anos cal AP ao presente, a vegetação, o clima e a paisagem modificaram consideravelmente. De 10.600 a ~9500 anos cal AP não houve preservação de pólen, os valores de C/N (~2 e 11) revelam a contribuição algal, o ?13C (~-20?) indica mistura de plantas C3 e C4 e inversões nas datações indicam o retrabalhamento do material. De 9500 a 7500 anos cal AP a vegetação era predominantemente herbácea, com mistura de C3 e C4 (?13C ~-17?). De 7500 a 700 anos cal AP, plantas C3 (?13C ~-30?) arbustivo-arbóreas dominam o registro polínico. De ~7000 a 6500 anos cal AP as herbáceasC4 (?13C ~-12?) são abundantes. A deposição de turfa iniciou em ~6500 anos cal AP, composta por plantas C3 arbóreas. Registros palinológicos desde o Holoceno inferior e a avaliação florística atual não revelaram a presença de espécies de distribuição disjunta com a Amazônia

No. of bitstreams: 1 Paulo Sergio Rezende.pdf: 4054612 bytes, checksum: 2c6b8eee75eccc25e2d2933ee9aeb901 (MD5) Previous issue date: 2010-02-09 / This study aims at investigating the phenomenon of identity constitution of 21 refugees in São Paulo, revealed and registered during the activities of the in class thematic workshops in a Portuguese as a foreign language course. In class thematic workshops are based on the concept of online thematic workshops (Rezende, 2003) developed from the concept of online workshops suggested by Freire (1998, 200). From the concept of online thematic workshops, I propose in class workshops that also present a thematic structure, considered as an input for discussions and communication in Portuguese, motivated by written and imagetic texts that foster the linguistic production process. This study presents a theoretic-methodological structure that considers complexity (Morin, 1990) as the ground on which experiences occur, as well as two main theoretical constructs: acculturation that is subdivided into immigration and refuge, as discussed by Ogbu (1982); Berry (1995); Gibson (1998) & McBrien (2005) and Identity, considering the possible dialogue that emerges from constructs such as home, territory, ethnic, memory and language, as presented by Cooper (1974); Pollack (1982); Bosi (1987); Hall (1990); Freire (1990); Mey (1998); Nair (1998); Ralha Simões (2001); Haesbaert (2002); Moita Lopes (2002); Rajagopalan (2003) e Cunha (2007). The experiences lived by the participants were registered as written and imagetic texts during a Portuguese as a foreign language course for refugees that started in the first semester of 2005. The course is structured in two 60-hour modules and the activities mentioned in this investigation became part of the regular didactic material used in this course. Considering the Hermeneutical-Phenomenologic Approach, this investigation aimed at describing and interpretating the mentioned phenomenon, by using the textualization and thematization processes proposed by van Manen (1990) and the refining and re-meaning movements outlined by Freire (2007). The experiences interpretation indicated that the phenomenon on focus in this study can be perceived from its two hermeneutical-phenomenological themes. The first, denominated Reflection, points to the way the participants reflect upon their past experiences, lived in their homeland, upon their impressions about the present refuge situation and upon their expectations for the future. The second theme, labeled as Belonging, presents the relations that reinforce the need to be part of a social context, and construct an individual and social history / O objetivo desta tese é investigar o fenômeno da constituição identitária de 21 refugiados em São Paulo, revelada durante a realização de atividades propostas sob o formato de oficinas presenciais temáticas inseridas em um curso de língua portuguesa como língua estrangeira, e incluindo produções textuais e imagéticas dos alunos. As oficinas presenciais temáticas resultam do desdobramento das oficinas virtuais temáticas (Rezende, 2003) desenvolvidas a partir do conceito de oficinas virtuais de Freire (1998, 2000). Partindo do conceito de oficinas virtuais temáticas, proponho com este trabalho uma experiência com oficinas presenciais que também apresentam uma estrutura temática que a partir de textos (escritos e/ou imagéticos) fomenta o processo de produção lingüística. Este estudo apresenta uma fundamentação teórico-metodológica que considera o pensamento complexo de Morin (1990) como o terreno no qual as experiências se desenvolvem, e dois construtos teóricos, a aculturação que se desdobra em imigração e refúgio a partir das discussões de Ogbu (1982); Berry (1995); Gibson (1998) e McBrien (2005) e identidade, considerando o diálogo entre os conceitos de lar, território, etnia, memória e língua a partir das contribuições de Cooper (1974); Pollack (1982); Bosi (1987); Hall (1990); Freire (1990); Mey (1998); Nair (1998); Ralha Simões (2001); Haesbaert (2002); Moita Lopes (2002); Rajagopalan (2003) e Cunha (2007). As experiências vividas pelos participantes foram registradas em textos escritos e imagéticos durante o curso de língua portuguesa para refugiados, iniciado no primeiro semestre de 2005. O curso é composto por dois módulos de 60 horas cada, e as atividades que fizeram parte desta investigação foram incorporadas ao material didático desenvolvido para o curso. A partir da abordagem Hermenêutico-Fenomenológica, esta investigação descreveu e interpretou o fenômeno, tendo como base os processos de textualização e tematização propostos por van Manen (1990) e os movimentos de refinamento e ressignificação propostos por Freire (2007). A interpretação das experiências registradas indicou que o fenômeno em foco pode ser compreendido a partir de dois temas hermenêutico-fenomenológicos. O primeiro, denominado Reflexão, aponta para a maneira como todos os envolvidos refletem sobre as vivências do passado em seus países de origem, sobre as impressões do presente na situação de refúgio e sobre os anseios para o futuro. A segunda, intitulada Pertencimento, indica as relações que reforçam o sentimento de pertencer a um território e o desejo de construir uma história individual e coletiva

This process is criss-crossed by the practices of the governmental and civil, national and international refugee support agencies. Our approach: the institutional analysis. In chapter one we reconstructed the trajectory of historical resistance of the Palestinian refugees since the end of the Turkish-Ottoman domination, as well as the foundation of the State of Israel, until the actual struggle for the end of the Israeli occupation and establishment of the State of Palestine. In chapter two we analyzed their resistance experiences on exile and in refuge camps. Our main theoretical supports: Nietzsche, Foucault, Agamben and Arendt. In chapter three we focused and analyzed the experiences of one Palestinian refugee family brought to Brazil to be resettled in the city of Mogi das Cruzes, state of São Paulo. With the perspectives of "power/knowledge" analytics, "will of truth" and "constitution of the subject" we were able to problematize humanitarian practices and public policies on refugees, specially the Brazilian ones and its pastoral/tutelage/victimization effects. We also explored the refugee existence, their creative powers and impasses / Utilizando-se de aporte teórico-metodológico da Análise Institucional a presente dissertação de mestrado busca identificar e analisar os modos de resistência experimentados por refugiados palestinos já impactados pelo deslocamento forçado e situação de refúgio - quando atravessados pelas práticas operadas pelas agências governamentais e da sociedade civil (nacionais e internacionais) que atuam no atendimento do refugiado trazido para reassentamento em território brasileiro. Para tanto procuramos refazer inicialmente a trajetória de resistência histórica dos refugiados palestinos, desde o fim da dominação turco-otomana, passando pela fundação do Estado de Israel, até chegar a seu estado atual de luta pelo fim da ocupação israelense e estabelecimento de um Estado palestino. Num segundo momento buscamos, com Nietzsche, Foucault, Agamben e Arendt, entre outros autores, analisar outra face dessa resistência, aquela operada no exílio e no refúgio nos campos de refugiados. E finalmente, com o objetivo de investigar essa resistência mais de perto, acompanhamos uma experiência bastante localizada de um grupo em especial de uma família de refugiados palestinos trazidos para reassentamento na cidade de Mogi das Cruzes, no Estado de São Paulo. Esse caminho de investigação foi realizado sob a perspectiva analítica do saber-poder, da vontade de verdade e da constituição do sujeito e buscou problematizar as práticas humanitárias e as políticas públicas dirigidas aos refugiados em território nacional, em seus efeitos pastorais/tutelares/vitimizadores. Nesse processo buscamos também evidenciar na existência desses refugiados suas potências criativas e seus impasses

Honey bees, Apis mellifera, play an important role in many ecosystems, pollinating a wide variety of native, agricultural, and exotic plants. The recent decline in the number of feral and managed honey bee colonies in North America, as well as the arrival of Africanized honey bees, have caused concern about adequate pollination for agricultural crops and natural plant communities. However, little is known about feral colonies, and the feral population is the source for Africanized honey bees as they spread and infiltrate managed populations. The goal of my dissertation was to examine the ecology of feral honey bee colonies, adding the spatial context necessary to understand the population ecology and patterns of resource use by feral honey bees on the Welder Wildlife Refuge. I defined the functional heterogeneity of feral honey bee habitat by identifying the suitability of different habitats for feral colonies based on the distribution and abundance of important resources (cavities, nectar, and pollen). I evaluated the distribution and abundance of feral colonies by examining nest site characteristics, population trends, and spatial and temporal patterns in cavity use. Lastly, I examined resource use by evaluating patterns in pollen collection and identifying where and when honey bees searched for resources. Overall, the Welder Wildlife Refuge provided excellent habitat for feral honey bees, supporting a high density of feral colonies. The dense live oak habitat was the best overall source for cavities, nectar, and pollen. Nectar and pollen were abundant throughout the year, with the exception of December and January, when a large number of honey bees searched for resources. Cavities did not appear to vary in their suitability for feral colonies based on measured structural and environmental attributes, since no cavity attributes were correlated with indices of cavity quality. However, the cavity quality indices varied between cavities, suggesting some cavities were more suitable for feral honey bees than others. Colonies were aggregated within the study area, probably due to the distribution of resources. The invasion of Africanized honey bees appeared to fragment the existing European population, with Africanized colonies aggregated in distribution and European colonies random in distribution.

Compreende-se a política de informação concebida como um pilar do sistema de refúgio global, construído e orientado social e historicamente pelo Estado, caracterizado como um recurso de poder e concretizado por meio de infraestruturas. Trata-se, assim, de uma lógica de poder baseado na informação que abarca duas perspectivas: direitos humanos e segurança nacional. O objetivo é produzir conhecimento sobre como se constrói essa política de informação, implicando como hipótese a existência de um dilema global entre as linguagens do tratamento humanitário e da vigilância para o controle. Adotou-se uma metodologia quali-quantitativa, baseada em análise convergente entre preceitos hipotético-dedutivos ⎯ de caráter exploratório por análise documental ⎯ e indutivos, com o auxílio de coleta de dados estatísticos, para análise descritiva e explicativa. Associa-se aos marcos teóricos, valorizando a interface da Ciência da Informação com outras áreas do conhecimento, um estudo empírico no arquivo de refugiados do Programa de Atendimento de Refugiados e Solicitantes de Refúgio (Pares-CARJ). Para compreender a ambiência onde se produz o fluxo de informação foram submetidas entrevistas semiestruturadas com profissionais e voluntários do Pares-CARJ, tendo em vista as possíveis relações institucionais entre esta e o Departamento de Polícia Federal (DPF). Como complemento às informações das entrevistas, foram coletados os motivos de refúgio que levaram os solicitantes a saírem de seus respectivos países. Com base na análise dos dados coletados observou-se como resultados que o dilema apontado faz parte da construção da política de informação sobre refugiados no Brasil. O regime de informação, que congrega inclusive políticas de informação, não se impõe de forma isolada, mas em convergência com outros regimes, a saber: de refúgio e de vigilância. Atentar para a infraestrutura conformadora da gestão das migrações significa compreender as linguagens que regem determinadas condutas político-operacionais, tendo em vista lógicas de dominação nas relações internacionais. Nesse sentido, revelam-se assimetrias em múltiplas esferas do poder informacional, seja em sua produção, sistematização, transferência ou, de maneira macro, no espaço político-decisório. / This research is an analysis about the information policy in the Brazilian refugee system, considering the notion of regime of information. Information policy is understood as a pillar of global refuge system, constructed and lead socially and historically by the State. It is characterized as a resource of power and made possible by infrastructure. So, it is treated as a logic of power based on information, which is oriented by two perspectives: human rights and national security. The objective is to investigate how this information policy is built in view of the regime theory, using as hypothesis the existence of a global dilemma between the languages of humanitarian treatment and of surveillance for control. A qualitative-quantitative methodology is adopted, based on a convergent analysis between hypothetic-deductive and inductive precepts ⎯ of exploratory character by documentation analysis ⎯ with the support of statistical data collection for descriptive and explicative analysis. Besides considering the interface between Information Science with other fields of knowledge, it was made an empirical study in the refugee archives at the Attendance Program of Refugees and Refuge Applicants at Caritas Archidiocesan of Rio de Janeiro (Pares-CARJ). To understand the environment where the flow of information has been produced, semi-structured interviews with professionals and volunteers of Pares-CARJ were made. As a complement to the information produced in the interviews, the motives of refugees were collected, which make them escape from their countries. Based on data analysis collected, it was observed that the dilemma suggested is part of the making of information policy about the refugees in Brazil. The regime of information is not imposed in an isolated form, but in convergence with other regimes, namely: regime of refuge and regime of surveillance. To observe the infrastructure that shapes the migration management allows to understand the languages that lead to certain political and operational behaviors, bearing in mind the logic of domination in international relations. In this way, asymmetries in multiple levels of informational power are revealed, as well as within the phases of production, systematization, transference, or ⎯ in a larger sense ⎯ in the political and decision making spheres.

We analyze the existence of limit cycle and canard cycle and we investigate the kinds of bifurcation that can occur. In the first model, Gause predator-prey with a refuge, we analyze the effects of a prey refuge on the ecosystem qualitative behavior. Employing the carrying capacity of the prey population in the Gause Model with a refuge we obtain the second model, for which we analyze the effects of the carrying capacity and we compare the results. In the third model we consider the continuous threshold harvesting strategies ocurring when the predator density is above a certain threshold. We note that the model has a complex dynamics with multiple internal equilibria and different types of bifurcation. / Neste trabalho estudamos o comportamento qualitativo global de três modelos predadorpresa. Analisamos a existência de ciclos limite e ciclos de canard e investigamos os tipos de bifurcações que podem ocorrer. No primeiro modelo, modelo predador-presa de Gause com refúgio, analisamos os efeitos do refúgio para as presas no comportamento dinâmico do ecossistema. Empregando a capacidade de suporte para a população de presas no modelo de Gause com refúgio obtemos o segundo modelo, para o qual analisamos os efeitos da capacidade de suporte e comparamos os resultados obtidos. No terceiro modelo consideramos as estratégias de colheita com limiar contínuo que é aplicada quando a densidade de predadores está acima de um certo limite e investigamos o comportamento dinâmico global. Observamos que o modelo possui uma dinâmica complexa com múltiplos pontos de equilíbrio e diferentes tipos de bifurcações.
