As Unidades de Conservação (UC) são espaços territoriais com características naturais relevantes, que têm a função de assegurar a representatividade de amostras significativas e ecologicamente viáveis das diferentes populações, habitats e ecossistemas. A Legislação Brasileira instituiu no ano de 2000 o Sistema Nacional de Unidades de Conservação da Natureza (SNUC). Dentre os diversos ambientes encontrados em território nacional, o Pampa tem uma representatividade de apenas 0,4% de sua área protegida, conforme consta no SNUC. O Refúgio da Vida Silvestre Banhado dos Pachecos (RVSBP) é uma UC de proteção integral estadual, localizada no Rio Grande do Sul e no Bioma Pampa, com uma área de 2.560 ha e representa cerca de 3,5% de todas as UC’s de proteção integral desse bioma. O RVSBP criada no ano de 2002, e ainda não possui plano de manejo, bem como carece de maiores investimentos e atenção. O uso de imagens de satélites como subsídio aos estudos ambientais já está consolidado e a interpretação destas imagens, a partir de diversos métodos, para classificar o uso e cobertura da terra, tem se tornado uma constante, munindo os pesquisadores de informações dos diversos processos que possam estar ocorrendo em uma determinada área de estudo, inclusive monitorando as mudanças ao longo do tempo. Os objetivos desta dissertação são os de verificar as mudanças no uso e cobertura do solo ocorridas entre 2001 e 2017 no RVSBP e em seu entorno direto de 10km, baseando-se na análise de imagens de satélite. Para tanto serão mapeadas as classes de uso e cobertura do solo, a partir de imagens dos satélites LANDSAT 5 – Sensor TM, LANDSAT 7 – Sensor ETM+ e LANDSAT 8 – Sensor OLI, para os anos de 2001, 2009 e 2017. O método de detecção das mudanças no uso e cobertura do solo aplicada foi a técnica de comparação pós-classificação para uma melhor compreensão das interações entre os fenômenos naturais e as atividades humanas. Essa técnica foi aplicada para os períodos de 2001 a 2009, de 2009 a 2017 e de 2001 a 2017. Para o período de 2001 a 2009 as mudanças ocorreram em 17,5% da área de estudo e em 19,9% do RVSBP. Para o período de 2009 a 2017 as mudanças ocorreram em 22,8% da área de estudo e em 23,9% do RVSBP. Para o período de 2001 a 2017 as mudanças ocorreram em 24% da área de estudo e em 32% do RVSBP. Dentre esses 32% a classe que apresentou os maiores acréscimos de área foram as classes de Agricultura – Arroz e de Associação de Sítio e produtores rurais, que respectivamente compreendem áreas de 410 hectares e de 135 hectares. As classes que foram mais impactadas com perda de área foram as classes Banhado e Vegetação Arbórea, que respectivamente compreendem áreas de 435 hectares e de 173 hectares. A análise de detecção de mudanças se mostrou efetiva como uma forma de monitoramento sistemático do uso e cobertura do solo do RVSBP e entorno, trazendo elementos importantes para a gestão da UC. / Conservation Units (UC) are territorial spaces with relevant natural characteristics, which have a role of ensuring the representativeness of significant and ecologically viable samples of different populations, habitats and ecosystems. Brazilian legistlation established in 2000 the National System of Nature Conservation Units (SNUC). Among the several environments found in the national territory, the Pampa has a representation of only 0,4% of its own protected area, according to SNUC. The Wildlife Refuge Banhado dos Pachecos (RVSBP) is a state UC of integral protection, located in Rio Grande do Sul and Bioma Pampa, with 2.560 ha and comprises about 3,5% of all integral protection UC of this biome. RVSBP was created in 2002, still does not have a management plan, and lacks greater investments and attention. The use of satellite images to suppott environmental studies is already consolidate and the interpretation of these images, using different methods, to classify land and use cover, has become a constant, providing researchers with information on the various processes that may be occurring in a particular study area, including monitoring changes over time. The objective of this dissertation is to verify the changes in the land use and cover occurred between 2001 and 2017 in RVSBP and in its surrounds of 10km, based on the analysis of satellite images. Therefore, the land and use coverage classes were mapped using images from the LANDSAT 5 - Sensor TM, LANDSAT 7 - ETM + and LANDSAT 8 - OLI Sensor, for the years 2001, 2009 and 2017. The method of detecting changes in land use and cover was the post-classification comparison technique for a better understanding of the interactions between natural phenomena and human activities. This technique was applied for the periods from 2001 to 2009, from 2009 to 2017, and from 2001 to 2017. For the period 2001 to 2009 the changes occurred in 17,5% of the whole study area and in 19,9% of RVSBP. For the period from 2009 to 2017, changes occurred in 22,8% of the whole study area and 23,9% of RVSBP. For the period from 2001 to 2017, changes occurred in 24% of the whole study area and 32% of RVSBP. Among these 32%, the class with the greatest increases in area were Agriculture – Rice crops and Site Association of Rural Producers, which respectively comprises areas of 410 hectares and 135 hectares. The classes that were most impacted with loss of area were the class Weands and Arboreal Vegetation, which respectively comprise areas of 435 and 173 hectares. The change detection analysis was effective as a way of systematically monitoring the land use and coverage of RVSBP and surroundings, bringing important elements to the management of the UC.

We also measured actual traffic flow intensity. Current and newly designed state is modelled with using of programme Aimsun, where we validate proposed solution.

This thesis deals with the influence of the European Migration Crisis in 2015 on the number of uses of selected features of totalitarian language in the rhetoric of ANO movement chairman Andrej Babiš, SPD chairman Tomia Okamura and IvČRN initiative leader Martin Konvička. This work aims to use new quantitative methods to examine over time the frequency and structure of the characters used in totalitarian language based on the concept of politics of eternity of the American historian Timothy Snyder. The occurrence of signs of totalitarian language was monitored on the social network Facebook in the period 2013-2017. The results of the analysis show an increase in the use of features of the totalitarian language with the onset of the migration crisis. In the end, a comparison of the monitored political actors and a contextual interpretation of the findings is given.

Children today have difficulty in finding places to play in the modern Swedish welfare society. Spontaneous play in the streets has almost vanished. When parents drive their children to different activities and institutions where the children are supervised and controlled by adults, the children are under constant surveillance. It’s not children or children’s desire to play that has changed, it is society. Despite this surveillance children still manage to create their own places. The aim of this study is to investigate when children create their own places in the preschool in a structured surveillance society as well as to find out what kind of materials they need to create such places. To be able to find out the answers to these questions I performed a mini ethnographic study in a preschool where I observed children. I followed the ethics rules of the Swedish research council. Ideas and concepts that I used were places for children – children’s places, breaking rules as a way to enter play, affordance as well as the theory of prospect refuge. Through these it was possible for me to identify and analyze when children were creating their own places as well as what materials that they used. The results show that children are capable of creating their own places, despite being under constant surveillance in the preschool. They managed to do so both indoors and outdoors. They both created their own places as well as used “places for children” as their own. By creating children’s places of their own, they get to break rules and use creativity as well as learn with their whole bodies, which benefits both their experience of joy as well as their learning.

Among exotic species that are capable of invading, establishing, and reaching pest status, few pose the range of impacts to biotic (e.g., competition with native species, predation, herbivory, introduction of other exotics) and abiotic (e.g., soil, hydrology) ecosystem components that can be attributed to the wild pig (Sus scrofa). Despite the presence of wild pigs throughout the southeastern United States for centuries, new invasions continue to occur in previously uninhabited and often under-investigated landscapes, including bottomland and upland forests. The recent invasion of the Sam D. Hamilton Noxubee National Wildlife Refuge (hereafter, NNWR) in east-central Mississippi represents an opportunity to understand not only a species invasion during an emergent stage, but also to improve and better inform the methods used to combat such species in forested landscapes. In recent years, the United States Fish and Wildlife Service has begun to observe direct impacts to this ecologically sensitive area which is critically important to not only migratory waterfowl but also a multitude of other faunal (e.g., amphibians, reptiles, and avian species of concern) and floral species. As a result, identifying wild pig spatial distributions (e.g., movements, occurrence) and estimating wild pig abundance in the NNWR have each increased in priority. My dissertation research has facilitated an improved understanding of how wild pigs have invaded this novel landscape through investigations of space use, abundance, and occurrence, and will better inform and improve efficiency of future monitoring and control efforts. Understanding how this wild pig invasion relates to the NNWR landscape may also provide information that can be used to better address wild pig invasions of similar landscapes, with added value for those that are similarly characterized by sensitive ecosystems (i.e., managed for migratory waterfowl, species of concern) that are currently faced with this emerging threat. Given the universality of many of the methodological approaches undertaken in this effort, this multifaceted investigation also provides broader implications for other landscapes and exotic species of interest.

Anthropogenic provisioning of water (water developments) to enhance abundance and distribution of wildlife is a common management practice in arid regions where water is limiting. Despite the long-term and widespread use of water developments, little is known about how they influence distribution, competition dynamics, and behavior of native species. To elucidate the potential influences of water developments on native species, we tested hypotheses concerning the occurrence and behavior of native kit foxes (Vulpes macrotis). First, we tested the indirect effect of water hypothesis (IEWH) which proposes that water developments negatively affect the arid-adapted kit fox by enabling a water-dependent competitor (i.e., coyote; Canis latrans) to expand distribution in arid landscapes. We tested the two predictions of the IEWH (i.e., coyotes will visit areas with water more frequently and kit foxes will avoid coyotes) and evaluated relative use of water by canids in the Great Basin and Mojave Deserts from 2010 to 2012. We established scent stations in areas with (wet) and without (dry) water and monitored visitation by canids to scent stations and water sources using infrared-triggered cameras. There was no difference in the proportions of visits to scent stations in wet or dry areas by coyotes or kit foxes at either study area. There was no correlation between visits to scent stations by coyotes and kit foxes. Visitation to water sources was not different for coyotes between study areas, but kit foxes visited water sources more in Mojave than Great Basin. The intense visitation to water by kit foxes in Mojave challenges our understanding that this species does not readily drink water. Our results did not support the IEWH in the Great Basin or Mojave Deserts for these two canids. Second, we tested three hypotheses that have been proposed to explain spatial variation in vigilance behavior. The predator-vigilance hypothesis (PVH) proposes that prey increase vigilance where there is evidence of predators. The visibility-vigilance hypothesis (VVH) suggests that prey increase vigilance where detection of predators is impeded or visibility is obstructed. The refuge-vigilance hypothesis (RVH) proposes that prey may perceive areas with low visibility (greater cover) as refuges and decrease vigilance. We evaluated support for these hypotheses using the kit fox, a solitary carnivore subject to intraguild predation, as a model. From 2010 to 2012, we used infrared-triggered cameras to record video of kit fox behavior at water developments in the Mojave Desert. The RVH explained more variation in vigilance behavior of kit foxes than the other two hypotheses (AICc model weight = 0.37). Kit foxes were less vigilant at water developments with low overhead cover (refuge) obstructing visibility. Based on our results, the PVH and VVH may not be applicable to all species of prey. Solitary prey, unlike gregarious prey, may use areas with concealing cover to maximize resource acquisition and minimize vigilance.

Snowy plovers (Charadrius nivosus) are small, ground-nesting shorebirds that are a species of conservation concern throughout North America. Despite increased efforts to understand factors contributing to the decline of snowy plover, little is known about habitat selection and breeding ecology of snowy plover for the large population found in the Great Basin. We tested hypotheses concerning the occupancy and nesting success of snowy plover. First, we identified factors influencing snowy plover nest survival at Great Salt Lake, Utah. We hypothesized that snowy plover would demonstrate differences in nest survival rates across years due to differences in habitat characteristics, predator abundance, human influence, resource availability, and fluctuating water levels. We conducted nest surveys at five sites along the Great Salt Lake to locate new nests or monitor known nests until nest fate was determined. We found 608 nests between 2003, 2005-2010, and 2012. The most common cause of nest failure was predation, followed by weather, abandonment, and trampling. Nest survival estimates ranged from 4.6 -- 46.4% with considerable yearly variation. There was no correlation between researcher activity (visits to nests and trapping of adults) and nest survival. Nests in close proximity to roads had lower survival than nests far from roads. Nests located on barren mudflats also had lower survival than nests in vegetated areas or near debris. We found that nests had a higher probability of survival as they increased in incubation stage. Because nesting areas around the Great Salt Lake host some of the largest concentrations of breeding snowy plover in North America, we suggest that managers consider measures to maintain suitable nesting habitat for snowy plover. Second, we determined factors affecting snowy plover occupancy and detection probabilities in western Utah between 2011 and 2012. We hypothesized that snowy plover would be associated with spring water flows and sparsely vegetated salt flats. We made repeated visits to randomly selected survey plots recording the number of snowy plover adults and habitat characteristics within each plot. We modeled the relationship between snowy plover detection probability and habitat and environmental characteristics. The detection probability was 77% (95% CI = 64 -- 86%) and did not vary by year. There was a positive relationship between ambient temperature and detection probability. Next, we modeled the relationship between snowy plover occupancy and individual habitat characteristics including distance to water, distance to roads, land cover types, and vegetative characteristics. Snowy plover occupancy did not vary by year and was estimated at 12% (95% CI = 7 -- 21%). Occupancy was best predicted by close proximity to water, playa land cover, and minimal shrub cover. We used habitat characteristics that best predicted snowy plover occupancy to generate a predictive habitat model that can help prioritize future snowy plover surveys and guide conservation efforts.

[pt] As migrações são movimentos populacionais presentes desde o início da humanidade e foram responsáveis pode moldar a sociedade. Os migrantes precisam e devem ser acolhidos com dignidade, todavia é importante analisar as causas de sua migração como forma de garantir que as pessoas só migrem no exercício de sua livre escolha. Nenhum ser humano deve ser forçado a migrar, a sair do seu país para buscar condições de vida dignas, se expondo aos inúmeros riscos e problemas oriundos desse tipo de migração. A responsabilidade de proteger tem potencial para ser uma ferramenta útil na prevenção de migrações forçadas considerando a segurança humana como uma meta a ser garantida e a soberania como uma responsabilidade e não, um direito absoluto do soberano. Além disso, a segurança humana, através da análise das situações inerentes à sua ausência é um importante sistema de alerta precoce visando a uma atuação com menos efeitos colaterais pela detecção de inseguranças humanas nos estágios iniciais. Embora seja importante a análise ainda que sucinta de alguns casos específicos onde a responsabilidade de proteger tenha sido, ou não, utilizada, o enfoque será prognóstico e focado na potencialidade dos conceitos e princípios, mesmo que nas situações pretéritas eles tenham sido mal utilizados. Como se demonstrará, muitos dos problemas na aplicação da responsabilidade de proteger são oriundos de questões políticas e não, do instituto em si. / [en] Migrations are population movements that exists since the beginning of humanity and were responsible for shaping the society. Migrants need and should be welcomed with dignity, but it is also important to analyze the causes of their migration as a way of ensuring that people only migrate at their free agency. No human being should be forced to migrate, to leave their country in order to seek for a decent living condition, exposing themselves to the numerous risks and problems that this type of migration brings with it. A study of how the responsibility to protect can be an useful tool to prevent forced migrations taking human security as a goal to be guaranteed and sovereignty interpreted as a responsibility, not an absolute right of the sovereign. In addition, human security through the analysis of situations inherent to its absence will be considered as an important early warning system in the search for a way of action with fewer side effects by detecting human insecurities in the early stages. A briefly analyze of some specific cases where the responsibility to protect has been used or not, is important. However, the focus will be prognostic with focus on the potential of the concepts and principles, even if in the past they have been misused. As will be shown, many of the problems in applying the responsibility to protect came from political issues rather than from the concept itself.

[pt] O presente trabalho realizou análise acerca do conceito de Grave e Genera-lizada Violação de Direitos Humanos (GGVDH), a fim de investigar quais são as fundações da definição ampliada de refugiado e como se deu a sua construção no Brasil. Através de pesquisa bibliográfica e documental, os dados usados nesta Dissertação de Mestrado foram coletados das seguintes fontes: teses, dissertações, livros e artigos; relatórios do governo, de organizações internacionais e não go-vernamentais; tratados, declarações e legislações. Esta dissertação buscou apre-sentar a arquitetura protetiva internacional da pessoa humana, investigando as conexões com os diversos mecanismos do Direito Internacional dos Direitos Hu-manos, suas complementaridades, seus regimes e aplicações regionais e nacionais para, então, explorar a trajetória do refúgio no Brasil não somente até a construção do conceito de GGVDH pelo governo, mas também no seu reconhecimento. Em um primeiro momento, deu-se a apresentação do arcabouço jurídico internacional, sua interdependência e relevância para a proteção humana, culminando na Decla-ração de Cartagena (1984) e seus processos revisionais. Posteriormente, desen-volveu-se o histórico brasileiro em matéria de refúgio, chegando ao período de redemocratização e incorporação do conceito de GGVDH pela Lei n° 9.474/1997. Por fim, passou-se à breve análise do reconhecimento de refúgio no Brasil por GGVDH, no intento de mapear o posicionamento do governo frente a essa defini-ção, sua aplicação e limitações, apontando algumas nuances e conclusões. / [en] The present study undertook an analysis about the concept of Gross and Generalized Violation of Human Rights (GGVDH), in an attempt to understand what the foundations of the extended definition of refugee are and how it has been constructed in Brazil. Through a bibliographic and documental research, the data used in this Master s Thesis was collected from the following sources: theses, dissertations, books and articles; reports from government, international and non-governmental organizations; treaties, declarations and legislation. This thesis sought to present the international protective architecture of the human person, investigating its connections with the various mechanisms of International Human Rights Law, their complementariness, regimes, regional and national applications to then, explore the refuge trajectory in Brazil, not only until the construction of the GGVDH concept by the government, but also its recognition. Initially, the international legal framework was presented, their interdependence and relevance to the human protection, culminating in the Cartagena Declaration (1984) and its revision processes. Subsequently, it demonstrated the Brazilian history in terms of refuge, up until the period of re-democratization and incorporation of the GGVDH concept by the Law n 9.474/1997. Finally, it presented a brief analysis of the refugee status recognition under GGVDH in Brazil, in an attempt to map the gov-ernment’s position in relation to this definition, its application and limitations, pointing out some nuances and conclusions.

[pt] Esta tese de doutorado investiga o acolhimento humanitário de pessoas LGBTI+ pela Operação Acolhida (2018-2022) como resposta do Brasil para o fluxo de migrantes e refugiadas venezuelanas no país, pensando um panorama dos serviços oferecidos e das questões que surgem no acolhimento e na integração dessa população no território brasileiro. Uma abordagem da performatividade de Judith Butler amparada por Jacques Derrida será usada como estratégia analítica para entender as práticas, os discursos, os protocolos e as regras empreendidas nesse caso pensando a reiteração de normas de gênero, sexo e sexualidade, do humanitarismo e de Estado. Nesse sentido, o texto é um enquadramento parcial de reiterações performativas da Operação Acolhida que podem (re)criar (im)possibilidades não-intencionais para migrantes e refugiadas venezuelanas LGBTI+. A realidade social LGBTI+fóbica traz consigo atravessamentos culturais locais e transfronteiriços em que imperam lacunas, silêncios, segregação e violências. Enquanto a lógica humanitária traz consigo as narrativas e protocolos da crise, da emergência estabelecendo pressa e reforçando ausências constitutivas; e o Estado traz consigo a demanda da contenção, da gestão e governo das populações e espaços, criando narrativas de (des)acolhida. Nessa sobreposição normativa e regulatória do contexto de acolhimento da Operação Acolhida, a população migrante e refugiada LGBTI+ necessita de integração a médio e longo prazo e de políticas que garantam seus direitos no país. Demandas de empregabilidade, saúde e assistência social se multiplicam em um universo em que o pensamento de curto prazo é reproduzido de forma central. Os limites, problemas e avanços da estrutura logística humanitária são foco do trabalho e delinearão os achados da pesquisa apontando para uma reflexão em torno da adaptação de protocolos e de uma crítica dialógica. / [en] This PhD thesis investigates the humanitarian reception of LGBTI+ people from Operação Acolhida (2018-2022) as a response from Brazil to the flow of Venezuelan migrants and refugees in the country, thinking about an overview of the services offered and the issues that arise in the encounter and integration of this population in the Brazilian territory. An approach to Judith Butler s performativity supported by Jacques Derrida will be used as an analytical strategy to understand the practices, discourses, protocols and rules undertaken in this case thinking about the reiteration of norms of gender, sex and sexuality, humanitarianism and the State. In this sense, the text is a partial framing of performative reiterations of the Operação Acolhida that can (re)create unintentional (im)possibilities for Venezuelan LGBTI+ migrants and refugees. The LGBTI+phobic social reality brings with it local and international cultural crossings in which gaps, silences, segregation and violence prevail. While the humanitarian logic brings with it the narratives and protocols of crisis, of emergency, establishing haste and reinforcing constitutive absences; and the State brings with it the demand for containment, management and government of populations and spaces, creating (un)welcoming narratives. In this normative and regulatory overlap of the reception context of Operação Acolhida, the LGBTI+ migrant and refugee population needs medium and long-term integration and policies that guarantee their rights in the country. Employability, health and social assistance demands multiply in a universe in which short-term thinking is centrally reproduced. The limits, problems and advances of the humanitarian logistical structure are the focus of this work and will outline the research findings, pointing to a reflection around the adaptation of protocols and a dialogic critique.
