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

Orientador: Célio Fernando Baptista Haddad / Resumo: Nesta tese exploramos a diversificação de espécies de anuros da Tribo Lophyohylini distribuídas na Mata Atlântica (MA) e Caatinga, biomas do Brasil. Para tanto, utilizamos dados genômicos e métodos de filogeografia estatística para analisá-los, uma abordagem robusta e até então ainda escassa na filogeografia dos organismos sul-americanos. Através do sequenciamento Sanger amostramos trechos de DNA mitocondrial (mtDNA) e através do sequenciamento de alto rendimento obtivemos polimorfismos de nucleotídeo único (SNPs) do DNA nuclear (nDNA). No primeiro capítulo, reunimos 82 amostras da espécie Aparasphenodon brunoi que apresenta distribuição nas terras baixas e costeiras do bioma MA, sendo considerada ideal para investigar o papel da instabilidade climática do Pleistoceno em seu processo de diversificação. Ainda no primeiro capítulo, para avaliar a influência do comportamento filopátrico, associado às diferenças no modo reprodutivo, na dispersão e consequentemente, no fluxo gênico entre populações, reunimos 72 amostras de A. arapapa e A. aff. brunoi. Estas tratam-se de espécies simpátricas, de distribuição mais restrita e com modos reprodutivos contrastantes o que as tornam ideais para esse tipo de comparação. De acordo com a inferência baseada em modelos demográficos, por volta do último máximo glacial (UMG) a população norte de A. brunoi se manteve estável enquanto que a do sul experimentou um gargalo seguido de expansão recente. Além disso, a população norte de A. brunoi apres...

To do so, we used genomic data and methods of statistical phylogeography to analyze them, a robust and until then still scarce approach in the phylogeography of South American organisms. Through the Sanger sequencing we sampled mitochondrial DNA (mtDNA) and through high-throughput sequencing we obtained single nucleotide polymorphisms (SNPs) from nuclear DNA (nDNA). In the first chapter, we collected 82 samples of the species Aparasphenodon brunoi that is distributed in the low and coastal lands of the AF biome, being considered ideal to investigate the role of Pleistocene climatic instability in its diversification process. In the first chapter, to evaluate the influence of philopatric behavior, associated with differences in reproductive mode, dispersion and consequent gene flow among populations, we also collected 72 samples of A. arapapa and A. aff. brunoi species. These are sympatric species with a narrower distribution and with contrasting reproductive modes, making them ideal for this type of comparison. According to the inference based on demographic models, around the last glacial maximum (LGM) the northern population of A. brunoi remained stable while the southern one experienced a bottleneck followed by recent expansion. In addition, the northern population of A. brunoi exhibits greater nuclear diver... (Complete abstract click electronic access below) / Doutor

La evolución es intrínseca en el ser humano y con nosotros evoluciona nuestro entorno. La industria de la construcción a manos de la necesidad del hombre, busca no solo un crecimiento horizontal territorial, sino también uno vertical. Sin embargo, esta proyección en las alturas se limita a una gestión plenamente espacial con poco interés en la capacidad de tránsito y zonas de refugio del agente humano durante un evento sísmico. Esta investigación realiza una evaluación de un escenario real existente del tramo de la avenida en estudio y el análisis de escenarios hipotéticos con variación del ancho de la zona de refugio. De este modo, se propone valores límite de altura y densidad poblacional de edificaciones para una Gestión Prospectiva del Riesgo Sísmico teniendo como ejemplo base un tramo de la Av. San Felipe en Lima-Perú. Se realizó el análisis de una evacuación eficiente de las edificaciones hacia la zona de refugio con modelos basados en el agente con el software Pathfinder, modelos tridimensionales (BIM), se analizó tiempos de evacuación, la influencia de las edificaciones, comportamiento humano y los parámetros urbanísticos zonales. Los resultados del presente trabajo establecen gráficamente la pertinente relación directa de la altura máxima permisible de los edificios proyectados con el ancho de la zona de refugio para una correcta evacuación. Como ejemplo se tiene un tramo de la Av. San Felipe con 7m de ancho de la zona de refugio correspondiente a 18 pisos como altura límite en los 10 edificios adyacentes considerando una longitud frontal total de 144m. / Evolution is intrinsic to human beings and our environment evolves with us. The construction industry at the hands of man's need, seeks not only a territorial horizontal growth, but also a vertical one. However, this projection in the heights is limited to a fully spatial management with little interest in the transit capacity and refuge areas of the human agent during a seismic event. This research carries out an evaluation of a real existing scenario of the section of the avenue under study and the analysis of hypothetical scenarios with variation in the width of the refuge area. In this way, limit values ​​of height and population density of buildings are proposed for a Prospective Management of Seismic Risk, taking as a base example a section of Av. San Felipe in Lima-Peru. The analysis of an efficient evacuation of the buildings towards the refuge area was carried out with models based on the agent with the Pathfinder software, three-dimensional models (BIM), evacuation times, the influence of the buildings, human behavior and the parameters were analyzed. zonal urban planning. The results of the present work graphically establish the pertinent direct relationship of the maximum permissible height of the projected buildings with the width of the refuge area for a correct evacuation. As an example, there is a section of Av. San Felipe with a 7m width of the refuge area corresponding to 18 floors as the limit height in the 10 adjacent buildings considering a total frontal length of 144m. / Tesis

Avec 80 millions de personnes déracinées à travers le monde, les espaces de refuge sont en train d’émerger comme les transformations urbaines les plus visibles des temps modernes. Ces espaces, dont la fonction première est d’abriter temporairement, servent souvent d’habitat pour les réfugiés pendant des décennies. Cependant, les États hôtes, majoritairement des pays en développement, persistent à accueillir les réfugiés selon des politiques à court-terme. Cet écart génère plusieurs tensions mais se manifeste explicitement dans la conception temporaire des espaces de refuge. Sur le plan théorique, alors que les migrations sont largement documentées, des connaissances limitées existent sur la reproduction de chez-soi. Les théories qui portent sur les espaces de refuge se concentrent surtout sur des enjeux géopolitiques et anthropologiques, négligeant l’espace en soi. Pauvres en nuances, elles classent ces espaces selon des conceptualisations dichotomiques souvent déconnectées du vécu des réfugiés. Cette recherche propose une nouvelle lecture des espaces de refuge à travers les lentilles du pouvoir, de la culture et de l’espace. Elle étudie l’appropriation de ces espaces en se basant sur l’exploration des pratiques sociales, économiques et politiques des réfugiés, de leurs interventions sur l’espace et du lien qu’ils développent avec leurs nouveaux environnements de vie. Elle révèle également l’influence des approches adoptées par la communauté internationale, les gouvernements d’accueil, les organismes humanitaires et les communautés hôtes. L’étude est qualitative exploratoire et adopte la méthode de l’étude de cas multiples. Cette approche permet d’acquérir une compréhension approfondie des perceptions des réfugiés des contextes sociopolitiques et économiques qui caractérisent leur vécu d’une part et de leurs représentations de l’espace d’autre part. Trois typologies d’habitat — deux habitations urbaines, deux campements informels et deux camps organisés — sont étudiées afin d’évaluer l’importance du type de l’espace par rapport à son appropriation. L’étude adopte l’ethnographie comme approche méthodologique complémentaire, dévoilant l’évolution des conditions de vie des réfugiés et la transformation de leurs espaces. Le cas à l’étude est celui des réfugiés syriens au Liban. Submergé par le nombre de réfugiés sur son territoire, le plus grand par nombre d’habitants au monde, le Liban exclut les réfugiés syriens des systèmes institutionnels, économiques et urbains dans le but de réduire leur accès au territoire, de limiter la durée de leur séjour et de prévenir la consolidation matérielle et immatérielle de leurs espaces. Toutefois, huit ans après, les stratégies adoptées par le gouvernement libanais se sont avérées infructueuses : le nombre des réfugiés syriens accueillis est sensiblement le même et leurs espaces se sont pour la plupart ghettoïsés. La thèse propose cinq résultats principaux : 1) l’enjeux central dans l’appropriation des espaces de refuge est un ensemble de géométries de pouvoirs politique, économique et social ; 2) la gouvernance faible de l’État d’accueil fragmente les systèmes traditionnels et permet l’émergence de structures de pouvoir informelles qui contrôlent les réfugiés et leurs espaces ; 3) l’exclusion des réfugiés exacerbe leur vulnérabilité et l’organise au profit de parties prenantes locales influentes. Elle réduit leurs chances d’émigrer et mène souvent à la ghettoïsation de leurs espaces ; 4) la typologie des espaces n’est pas centrale par rapport à leur appropriation ; 5) l’enracinement de l’identité dans le lieu d’origine est une idée basée sur des considérations politiques anti-migratoires. Les espaces de refuges évoluent, selon les opportunités et les défis dans le milieu d’accueil, suivant un continuum entre non-lieux temporaires et lieux de vie socioculturels. En transcendant leur marginalisation et leur homogénéisation, cette recherche dévoile la réalité intime des espaces de refuge. Elle montre que souvent, ils deviennent des chez-soi, lieux de vie quotidiens qui abritent des individus qui forment des groupes sociaux culturellement distincts et économiquement hiérarchisés. D’un point de vue théorique, elle montre que l’accueil des réfugiés est souvent basé sur l’hostipitalité, une hospitalité hostile qui vulnérabilise les réfugiés et facilite leur exploitation. Elle révèle que l’appropriation des espaces de refuge augmente proportionnellement avec l’inclusion institutionnelle et l’autonomisation socioéconomique des réfugiés, concourant à la reproductibilité rhizomique de leur identité individuelle et collective. D'un point de vue pratique, cette recherche démontre que, sous prétexte de raccourcir la durée de l’accueil des réfugiés, les politiques d’accueil sont en réalité adoptées dans l’intérêt économique et politique d’acteurs étatiques et privés. Dans le but d’atteindre une meilleure justice spatiale, elle recommande aux gouvernements d’accueil un changement de paradigme à travers l’adoption de stratégies plus inclusives à l’égard des réfugiés menant à leur autogestion et leur développement et d’approches adaptées à l’usage et à la durée de leurs espaces. / With 80 million people uprooted around the world, refuge spaces are coming to be the most visible urban transformations of modern times. These spaces, whose primary function is to shelter, often accommodate refugees for decades. Yet, host states, mostly developing countries, continue to host refugees without adopting comprehensive, long-term strategies for their integration, causing acute political, socio-economic, and humanitarian problems. The lack of a long-term solution is explicitly revealed by the conceptions of refugee spaces, often designed as temporary solutions. From a theoretical perspective, while social scientists and geographers have widely documented the geopolitical and anthropological aspects of forced migrations, they have neglected the concept of space appropriation and the production of place identity in refugee spaces. Indeed, their classification of space/place is often based on dichotomous conceptualizations and differs from refugees’ real-life experience. This research examines refugee spaces through the lenses of power, culture, and space. It provides new evidence on the appropriation of these spaces through refugees’ social, economic, and political practices, their interventions on space, and their perceptions of their new living environment. It also examines the impact of the strategies adopted by the international community, host governments, humanitarian organizations, and local communities. The research method is qualitative and exploratory; it is based on a multiple case study design. This methodological approach provides an in-depth understanding of refugees' perceptions on the socio-political environment undergirding displacement and on their representations of space. Three space typologies — urban dwellings, informal settlements, and organized camps — are studied with the purpose of assessing the relevance of the space-type in relation to its appropriation. The study uses ethnography as a complementary methodological approach, shedding light on the evolution of refugees’ living conditions over time and the transformation of their spaces from a cultural standpoint. It specifically focuses on Syrian refugees in Lebanon, a country which hosts the largest number of refugees per capita in the world. Overwhelmed by the number of refugees hosted, Lebanon excludes Syrian refugees from formal legal, economic, and urban systems, limiting their access to the territory, reducing the duration of their stay, and preventing the tangible and intangible consolidation of their living spaces. Yet, eight years later, the strategies adopted by the Lebanese government have proven unsuccessful: the number of Syrian refugees is roughly the same as at the beginning of the conflict and most of their spaces have been ghettoized. Results show that: 1) complex geometries of political, economic, and social powers determine the appropriation of refugee spaces; 2) weak state authority fragments traditional governance systems which leads to the emergence of informal power structures that control refugees and their spaces; 3) refugees’ exclusion exacerbates their vulnerability, while benefitting local stakeholders, subsequently reducing their chances of emigration and leading to the ghettoization of their living spaces; 4) the typology of spaces is not a major variable in relation to their appropriation; 5) the rooting of identity in the place of origin is an idea based on anti-migration political viewpoints; refugee spaces can evolve along a continuum between temporary non-places and socio-cultural places of life depending on the opportunities and challenges in the host context. Transcending the stigmatization, marginalization, and homogenization of refugee spaces, this research reveals the intimate reality of these spaces. It shows that they often become places of everyday life for refugees who form culturally dissimilar and economically hierarchical social groups. From a theoretical point of view, this research shows that hosting policies are often based on hostipitality, or a hostile form of hospitality which exacerbate refugees’ vulnerability and facilitates their exploitation. It shows that refugees’ appropriation and control of their living spaces increase proportionally with their legal inclusion and their socio-economic empowerment by the host state, inciting the rhizomic reproducibility of their individual and collective identity in their new habitat. From a practical point of view, the research shows that hosting policies adopted on the pretext of shortening the duration of refugees’ settlement are in fact in the interest of state and private actors. With the purpose of achieving spatial justice, the study recommends a change of paradigm in refugee policies with approaches that are more inclusive towards refugees leading to their self-management and their development, and adapted to the use and duration of their living spaces.

The subject of my Master’s thesis is the variant redevelopment of intersections I/56 and II/469 in Hlučín. Both interesections are situated nearby bus terminal. Extent of adjustment obstructs the object of former granary. There are checked spatial options for adjusting both existing intersections to the roundabouts. In the frame of variants, there is a different manner of solution of structural layout of both intersections, possibility of connection of bus terminal and transfer of pedestrian traffic across designed intersections. Part of Master’s thesis is traffic survey and capacity analysis of designed intersections.

The main objective of the thesis is to design a roundabout in the depth of anurbanistic study. The concerned crossroad is found in a village of Prestanov where the roads I/13 and II/253 intersecting. The goal of a supposed reconstruction is to change the traffic scheme of the current crossroad to design a roundabout. The change would provide the traffic flow going from the minor road II/253 with free-flowing traffic and better safety issues. Three new versions of the crossroad were designed. The spiral type roundabout is pursued further to the final design. The drawings and the technical report are also included. On top of that, the thesis contains an engineering geology survey and a road capacity assessment.

La crise des États-nations face aux migrant·e·s, comme la réactivité publique par rapport aux enjeux de justice sociale concernant les groupes minoritaires, participe à faire de l’hospitalité un sujet criant. Pourtant, la notion ne génère en elle-même aucune polémique et ne fait que rarement l’objet de remises en cause. Ce mémoire apporte un regard critique sur ce qu’est l’hospitalité et sur les manières dont elle est pratiquée. À cet effet, l’étude du phénomène est menée à partir du point de vue des privilèges des hôtes plutôt que de celui de la vulnérabilité des personnes accueillies. D’abord, il s’agit de mettre en perspective les acceptions vertueuse et principielle de l’hospitalité. Comprise en tant que pratique de l’accueil, l’hospitalité est ensuite redéfinie selon trois modalités (spatiale, sociale et procédurale) en réponse aux façons dont l’hospitalité est la plus fréquemment problématisée dans les discours savants (autour du chez-soi, de la figure de l’étranger et de l’invitation par exemple). Puis, il est question des manières d’accueillir spécifiques relatives à la frontière, au seuil, au camp et au refuge. Avec l’œuvre Las reglas del juego / The Rules of the Game (2000 ‒ 2001) de Gustavo Artigas, il apparaît que penser l’hospitalité par ses limites renvoie à l’idée d’accessibilité. L’accueil y représente une admission conditionnelle et une régulation des admis·es (frontière) ou un enjeu d’adaptation à autrui (seuil). Le projet État d’Urgence (1998 ‒ 2010) de l’ATSA permet quant à lui d’interroger l’accueil sous l’angle de l’inclusion sociale. Tantôt, l’hospitalité devient synonyme de mise à l’écart d’un régime d’oppression (camp), tantôt du refus de collaborer au dit régime en son sein même (refuge). En somme, le dialogue entre les écrits savants et les œuvres d’art participatif dévoile les relations de pouvoir dans l’accueil qui sont à même de définir l’hospitalité, sa visée opportuniste et ses effets incertains. / The crisis of nation-states regarding migration and public responsiveness to issues concerning minority groups contribute to make hospitality a topic of the hour. However, the concept in of itself does not rise any polemic and appear to be rarely challenged. This paper therefore seeks to provide a critical look at what hospitality actually is and at how it is practiced. The phenomenon was studied from the perspective of the hosts and their privileges rather than the vulnerability of the people welcomed. In the first chapter, the meaning of hospitality as a virtue, as a principle and as a practice, which are common modes of defining the subject in the scholarly publications, was put into perspective. A new definition of hospitality was then proposed drawing on the three modalities of its practice (spatial, social and procedural). This definition respond to the ways in which hospitality is most frequently problematized in the literature (around the home, the figure of the stranger and the multiple actions supposed to provide hospitality such as invitation, accommodation, care, etc.). In the second chapter, each specific way of welcoming that implies the border, the threshold, the camp and the refuge is discussed. Thereon, Gustavo Artigas' Las reglas del juego / The Rules of the Game (2000 ‒ 2001) reveals that the limits of hospitality represent a matter of conditional admission and control (border) or of adaptation to others (threshold). Also, ATSA's État d'Urgence (1998 ‒ 2010) allows to examine hospitality under the paradigm of social inclusion. From this angle, welcoming becomes synonymous either with taking a population aside from an oppressive regime (camp), or with a refusal to collaborate with the regime from the inside (refuge). In short, the dialogue between scholarly literature and participatory art uncovers the power relations that define hospitality, its opportunistic goals and its ambiguous effects.

The general aim of this thesis is to analyse and compare archival materials concerning Huguenot and Walloon families, and to carry out a sample analysis of these and whether it is possible to find the cities of origin where they lived until the Nantes Edict was revoked in 1685 and they were forced to flee because of their reformed faith. The selected sources consist primarily of materials from the French departmental archives and materials accessed via the internet as digitalized pictures (.jpg-files) and so on.  The descriptive section of this thesis concerns literature about Huguenot and Walloon history, genealogy, and exodus, as well as research into archive and information sciences primarily access and findability. I begin by describing the overall view, to set the stage. Then, I investigate the European archives. Thirdly, I proceed with a time intensive sample analysis of 30 known families from varying places in France, Belgium, Norway, and Sweden and finally, I attempt to clarify the difficulties that arise concerning findability and why those arise.  The method is genealogical research on sources accessible by the internet, and it turns out in the conclusion that 50% of the chosen families can be found in their home parishes, even if findability issues often show themselves, both because we’re talking about a religious minority, people fleeing the country, and a large geographic area. It was heartening and surprising however, that my search was successful in finding so many of the 30 families, and interesting to note which areas were easier to search than others.  The findability issues are further deepened because the archives’ Internet pages are not optimally designed as their metadata is often insufficient, and the pages furthermore so difficult to navigate since they are both widely different from each other, and because they are not, in the words of Wendy M. Duff, managing to hit the “perfect pivot point” between archiving and usage. Reasons for this include a lack of descriptive data attached to the digitalised files, and because .jpg-files are often not searchable, as observed as well by Catherine Styles.  More user research is required in the area of archives, so that better and easier access to these webpages can be guaranteed, especially given varying userbases and their differing needs in searching.

[pt] As Américas estão passando pela maior crise de refugiados da história, sendo caracterizada pela elevada presença de crianças desacompanhadas em migração. Este trabalho busca realizar um estudo comparativo entre as políticas de acolhimento para esse grupo, considerando refugiados venezuelanos no Brasil e do Triângulo Norte da América Central nos EUA. Examinou-se se os processos de acolhida e suas aplicações são inclusivos e adequados a recepção de menores desacompanhados, à luz das diretrizes de organismos de referência na área. Este estudo conclui que os processos de acolhida brasileiros almejam ser receptivos e inclusivos, seguindo o princípio do melhor interesse da criança. No entanto, os procedimentos carecem maior robustez e estrutura para serem eficazes. Enquanto isso, as políticas de acolhimento nos EUA são mais amadurecidas e possuem os recursos necessários para sua implementação. Entretanto, o acolhimento é hostil, assemelhando-se ao processo de detenção, não havendo distinção institucional clara entre a proteção da criança refugiada e o controle de fronteiras / [en] The Americas are experiencing the worst refugee crisis in history, characterized by the elevated presence of unaccompanied children. This work seeks to conduct a comparative study between reception policies for this group, considering Venezuelans in Brazil and nationals from the Northern Triangle of Central America in the USA. It was examined whether the reception processes and their applications are inclusive and adequate for unaccompanied minors, in light of the guidelines of reference organizations in the area. This study concludes that the Brazilian reception process aims to be receptive and inclusive, following the principle of the best interest of the child. However, the procedures lack more robustness and structure to be effective. Reception policies in the US are more mature and have the resources available for implementation. However, the reception is hostile, similar to the detention process, with no institutional distinction between refugee child protection and border control.
