Full textAbstract:
Background.Ecological communities are dynamic collections whose composition and structure change over time, making up complex interspecific interaction networks. Mutualistic plant–animal networks can be approached through complex network analysis; these networks are characterized by a nested structure consisting of a core of generalist species, which endows the network with stability and robustness against disturbance. Those mutualistic network structures can vary as a consequence of seasonal fluctuations and food availability, as well as the arrival of new species into the system that might disorder the mutualistic network structure (e.g., a decrease in nested pattern). However, there is no assessment on how the arrival of migratory species into seasonal tropical systems can modify such patterns. Emergent and fine structural temporal patterns are adressed here for the first time for plant-frugivorous bird networks in a highly seasonal tropical environment.Methods.In a plant-frugivorous bird community, we analyzed the temporal turnover of bird species comprising the network core and periphery of ten temporal interaction networks resulting from different bird migration periods. Additionally, we evaluated how fruit abundance and richness, as well as the arrival of migratory birds into the system, explained the temporal changes in network parameters such as network size, connectance, nestedness, specialization, interaction strength asymmetry and niche overlap. The analysis included data from 10 quantitative plant-frugivorous bird networks registered from November 2013 to November 2014.Results.We registered a total of 319 interactions between 42 plant species and 44 frugivorous bird species; only ten bird species were part of the network core. We witnessed a noteworthy turnover of the species comprising the network periphery during migration periods, as opposed to the network core, which did not show significant temporal changes in species composition. Our results revealed that migration and fruit richness explain the temporal variations in network size, connectance, nestedness and interaction strength asymmetry. On the other hand, fruit abundance only explained connectance and nestedness.Discussion.By means of a fine-resolution temporal analysis, we evidenced for the first time how temporal changes in the interaction network structure respond to the arrival of migratory species into the system and to fruit availability. Additionally, few migratory bird species are important links for structuring networks, while most of them were peripheral species. We showed the relevance of studying bird–plant interactions at fine temporal scales, considering changing scenarios of species composition with a quantitative network approach.

Full textAbstract:
Purpose The purpose of this study is to navigate the challenges irregular migratory flows generate for cities and urban systems. The migration and refugee crises that challenged Europe in 2015-2016 revealed that the developed world cities and urban areas are largely unprepared to address challenges that irregular migratory flows generate. This paper queries the smart and resilient cities’ debates, respectively, to highlight that migration-related challenges and opportunities have not been explicitly addressed in those deliberations. This creates a disconnect between what these debates promise and what cities/urban systems increasingly need to address on a daily basis. Subsequently, a way of bridging that disconnect is proposed and its policy-making implications discussed. Design/methodology/approach To suggest ways of navigating irregular migration-inflicted challenges cities/urban areas face, a nexus between the smart cities and resilient cities’ debates is established. By placing advanced sophisticated information and communication technologies (ICTs) at the heart of the analysis, a novel dynamic ICTs’ enabled integrated framework for resilient urban systems is developed. The framework’s dynamics is defined by two hierarchically interconnected levers, i.e. that of ICTs and that of policy-design and policy-making. Drawing from qualitative analysis and process tracing, the cross-section of policy design and policy-making geared towards the most efficient and ethically sensitive use of sophisticated ICTs is queried. Subsequently, options available to cities/urban systems are discussed. Findings The ICTs’ enabled integrated framework for resilient urban systems integrates the effectiveness of migrants and refugees’ policy design and policy-making in human-centred thinking, planning and policy-design for resilient urban systems. It places resilient approaches in the spotlight of research and policy-making, naming them the most effective methods for promoting a humanistic smart cities and resilient urban systems vision. It highlights critical junctions that urban systems’ stakeholders must consider if the promise of emerging sophisticated ICTs is to be employed effectively for the entire society, including its most vulnerable members. Research limitations/implications First, when designing ICTs’ enabled integrated resilient urban systems, the key stakeholders involved in the policy-design and policy-making process, including local, national and regional authorities, must employ a holistic view to the urban systems seen through the lens of hard and soft concerns as well as considerations expressed by the receiving and incoming populations. Second, the third-sector representatives, including non-governmental organizations (NGOs) and other actors, need to be seen as peers in integrated humanistic networks, thereby contributing critical, unbiased knowledge flows to infrastructures, which promote fair and inclusive participation of migrants and refugees in local economies. Practical implications The ICTs’ enabled integrated framework for resilient urban systems promotes a humanistic smart cities’ and resilient urban systems’ vision. It suggests how to design and implement policies apt to meet the needs of both receiving and incoming populations along value chains specific to smart and resilient cities. It promotes emerging sophisticated ICTs as the subtle, yet key, enabler of data ecosystems and customized services capable of responding to critical societal needs of the receiving and the incoming populations. In addition, the framework suggests options, alternatives and strategies for urban systems’ stakeholders, including the authorities, businesses, NGOs, inhabitants and ICTs’ providers and vendors. Originality/value The value added of this paper is three-fold. At the conceptual level, by bringing together the smart cities and resilient cities debates, and incorporating sophisticated ICTs in the analysis, it makes a case for their usefulness for cities/urban areas in light of challenges these cities/urban areas confront each day. At the empirical level, this analysis maps the key challenges that cities and their stakeholders face in context of migratory flows and highlights their dual nature. At the policy-making level, this study makes a case for a sound set of policies and actions that boost effective use of ICTs beyond the smart technology hype.

Full textAbstract:
This thesis addresses a gap in the understanding of migrant networks in migrant livelihood vulnerability. To date there has not been a systematic analysis of migration as a livelihood activity that both enables households to manage risks while also representing a source of risk itself. This limits the understanding of migration as a livelihood activity. Vulnerability in this thesis is defined as a function of household capability, risk exposure and the outcome of managing risk. Migrant networks are a resource for migrant households that influences their capability to manage risks by channelling information and support, by providing adaptation mechanisms, and through providing linkages between sending community and migrant. Migratory livelihoods are explored through examination of rural to rural migration between lowland and upland Vietnam. Giao Thuy District is a migrant sending area in the densely populated Red River Delta in the North, while Cat Tien National Park is a destination area located at the Central Highland frontier that is characterised by continuous in-migration and a growing export oriented agro-economy primarily in coffee. Data were collected through household surveys and semi-structured interviews to examine how migrant networks function in three different stages of the migration process. These are (a) migration decision making, (b) adaptation to new conditions, and (c) managing economic uncertainty in the destination. The research demonstrates that migrant networks have positive effects on migrant livelihood vulnerability by facilitating diversification of income earning activities. They also exacerbate migrant livelihood vulnerability through exposing households to additional risk. Resources transferred through migrant networks lower the costs and risks of migration, thereby enabling households to use migration as an asset accumulation or as a risk coping strategy. However, as a greater range of households are able to move, the rapid chain migration from similar cultural and ethnic backgrounds results in negative impacts on the economic, social, and environmental context in the Central Highlands which in turn reduces resource availability for migrants. Migrants who invest capital into coffee farming do so in an environment of high global market variability and a poorly developed social welfare system. In order to draw on additional resources to manage these uncertainties, migrants maintain links to household members in the sending community. However, while the pooling of resources among network members enables migrants to mitigate, and cope with, economic shocks in the destination, it also transfers these risks to network members in the sending area. These findings indicate that migration as a livelihood activity can potentially increase the vulnerability to losses of welfare of both secure and coping migrant households, particularly when migrants rely on migrant networks as a safety net. The analysis of migrant networks in migratory livelihoods enables a more nuanced understanding of the benefits and dangers of diverse and multi-local livelihoods.

Entre les moltes comunitats migratòries existents al món, aquesta tesi doctoral estudia fonamentalment la comunitat dels ciutadans i ciutadanes pakistanesos que viuen a Catalunya, i també sobre les xarxes que han establert per consolidar i expandir la seva presència. <br/>Aquesta tesi a més a més, estudia la situació de les famílies i de les comunitats d'origen al Pakistan per entendre millor els processos que han conduit cap a aquest fenomen migratori, la situació actual de la població pakistanesa a Catalunya, l'impacte de la migració en les famílies dels migrants al Pakistan i les perspectives a curt i mitjà termini d'aquest moviment de població. <br/>La comunitat pakistanesa a Catalunya presenta un cas d'estudi interessant, no pel fet migratori en sí mateix, sinó perquè aquest moviment migratori té lloc sense que existissin lligams culturals, històrics i lingüístics previs entre el Pakistan i Catalunya, i perquè l'expansió ha estat molt ràpida en aquests darrers anys. <br/>Un segon objectiu d'aquesta tesi és donar veu als participants en el projecte d'investigació i, a través d'ells, a la comunitat pakistanesa a Catalunya i a les seves famílies i comunitats d'origen. <br/>Durant la segona meitat del segle vint, es van desenvolupar vàries teories, models i sistemes per intentar explicar la migració internacional. La realitat social i econòmica de la població pakistanesa a Catalunya i de les seves famílies en el Pakistan però, no s'hi ajusta gaire. Ara bé, totes elles contenen elements que poden ajudar a la comprensió del fenomen migratori i per tant convé considerar-les com un conjunt d'instruments que ajuden a capturar (no és incorrecta però la trobo un pèl forçada: copsar? captar? comprendre? ) una realitat complexa i constantment canviant. <br/>La investigació ha permès de concloure que l'emigració pakistanesa a Catalunya està fonamentada en el diferencial econòmic entre els dos països, un diferencial que compensa els costos de la migració. La gran majoria de la població pakistanesa a Catalunya hi tenien una "àncora" abans de venir. L' origen comú de molts d'ells indica l'existència de xarxes migratòries basades en la relació familiar i/o social. <br/>L'objectiu principal dels migrants és poder oferir una vida millor a les famílies, un objectiu a mitjà i llarg termini, atès que l'objectiu inicial consisteix en recuperar la inversió que suposa per a cada família enviar un dels seus a Catalunya. Facilitar l'arribada de nous immigrants no sembla ser un objectiu, sinó que és un fet que succeeix sense que es busqui. <br/>Catalunya no és pas la destinació preferida dels migrants. La seva arribada és més aviat el resultat d'una curosa anàlisi cost/benefici en el sentit que Catalunya constitueix una destinació "fàcil" i "bé de preu". <br/>En resum, es pot dir que la migració pakistanesa a Catalunya continuarà augmentant en els propers anys amb l'arribada principalment d'homes, però també de dones i nens i nenes, sempre i quan les condicions econòmiques i polítiques continuïn més o menys igual. Aquest creixement farà que els enclavaments pakistanesos a la ciutat de Barcelona s'enforteixin. Alhora, sorgiran altres enclavaments a la mateixa ciutat i a la zona metropolitana, i possiblement també a Girona i Tarragona, i més tard a Lleida. Aquests enclavaments funcionaran com un pol d'atracció per a nous migrants pakistanesos. <br/>És molt possible que, seguint el model de migració pakistanesa a altres països europeus, els migrants pakistanesos s'esforcin per integrar-se en el món econòmic, però només els individus amb un nivell educatiu alt estaran disposats a desenvolupar lligams culturals i socials amb els catalans. La majoria de la població pakistanesa preferirà viure al marge de la societat catalana. <br/>Tot i que molts voldrien tornar al Pakistan, és probable que la majoria romangui a Catalunya definitivament i amb la seva presència contribueixi a l'expansió continuada del moviment migratori pakistanès a traves de l'enfortiment de les xarxes migratòries i dels enclavaments pakistanesos.<br>Among the many migrant communities in the world, this doctoral dissertation focuses on the Pakistani community in Catalonia and the networks they have established to consolidate and expand their presence there. <br/>In addition, this thesis studies the situation of families and the communities of origin in Pakistan to try to understand the processes that have led to this migratory phenomenon, the present situation of the Pakistani population in Catalonia, the impact of migration on their families in Pakistan, and the short and medium term prospects for this migratory movement. <br/>The Pakistani community in Catalonia presents an interesting case study not because of the migratory movement itself, rather because the movement takes place in the absence of cultural, historical or linguistic links between Pakistan and Catalonia, and because of its fast expansion. A second objective is to give voice to the participants in the research and through them, to the Pakistani community in Catalonia and their families and communities of origin. <br/>During the second half of the 20th century, many theories, models and systems were developed to try to explain international migration. However these theories fail to explain the social and economic reality of the Pakistani population in Catalonia and their families in Pakistan. Nonetheless, they may help understand the migratory phenomenon, and therefore they may be used as a set of instruments that help capture a complex and constantly changing reality. <br/>The research shows that Pakistanis migrate to Catalonia prompted by the economic differential between the two countries and the perceived low risks/costs attached to it. The great majority of Pakistanis in Catalonia had an anchor before proceeding, be it a friend, a relative or even an acquaintance, that was crucial in facilitating their arrival and initial introduction. The common geographical origin of most of them shows the existence of migratory networks based on family and social relations. <br/>The overall objective is to provide more and better for their families. But this is a medium or long term objective. Initially most of them need to recoup their or their family's initial investment to send them abroad, and only afterwards they can start saving for their families. Facilitating the arrival of other migrants is not an objective per se, bur rather an unintended effect. <br/>Catalonia is not the migrants' preferred destination. The research findings indicate that the choice was made on the basis of a cost benefit analysis, i.e. they selected the destination which was the least costly and which brought the greatest benefits in the short term. <br/>In summary, in the coming years Pakistani migration to Catalonia will continue and will probably grow exponentially through the arrival of mostly men, but also women and children, as long as economic and political conditions remain the same, or experience only minor variations. This growth will lead to the strengthening of existing Pakistani enclaves in Barcelona city, and the emergence of new ones in Barcelona and in the Metropolitan Area of Barcelona, and to a lesser degree in Girona, Tarragona and eventually Lleida. These enclaves will function as a pull factor attracting many more Pakistanis to Catalonia. <br/>Based on the research findings and the experience of Pakistani migratory movements to other European destinations, Pakistani immigrants are likely to remain separate from the local population. Their desire to integrate will focus on the economic sphere, and only a few, better educated individuals, will be ready to establish and develop cultural and social links with the Catalan society. There is likely to be a strong resistance to adopt any mores of the host society and particularly to merge with it. <br/>Despite their longing for Pakistan and Pakistani society, the majority of them will remain in Catalonia and will settle here, thus sustaining the Pakistani migratory movement and contributing to its expansion through the strengthening of existing enclaves and the emergence of new ones.

<p>This study investigates ways in which migratory trajectories relate to the gradual insertion and eventual integration of immigrants. It therefore shows the contribution of social capital in the migration and insertion into the entrepreneurial city of the host country. The focus of the study is on immigrants of African origin. It is hypothesized that immigrants of different nationalities in South Africa use <br>particular assets to engage in street vending as a way of insertion into their new environment. Data were obtained through a survey of two hundred and eight (208) respondents conveniently <br>selected. The survey was carried out in five suburbs of Cape Town and as well as at some major road junctions where these vendors are found. The Statistical package for Social Science (SPSS) was used to analyse the data. The results showed that nationality was an important determinant of the migratory trajectories of immigrant vendors. Migration has been on the increase with the <br>improvement in technology and globalization. In the same light, migration into South African cities mainly from the rest of Africa and Asia took an upward trend especially after the fall of Apartheid <br>Regime and the advent of democracy in the nineties. Street vendors form part of these immigrants in South Africa. Many of them especially from other African countries find it a suitable means of <br>survival. Faced with the difficulty of getting jobs in South Africa, immigrants resort to informal trading as a starting point for survival. They may change to other activities depending on certain variables like duration of stay, level of education, age, sex, marital status, social capital and networks. Coming from different socioeconomic, cultural and political backgrounds, these immigrants <br>resort to different ways of migrating and forms of adaptation aimed at sustaining their livelihood in their new environments. Most studies in the field of migration and entrepreneurship focus on <br>remittances by the migrants as well as their impact on both their place of departure and on the place of destination. Little attention is paid to the way they migrate and how they insert themselves in the entrepreneurial city.<br />

Orientadora: Profa. Dra. Adriana Capuano de Oliveira<br>Dissertação (mestrado) - Universidade Federal do ABC, Programa de Pós-Graduação em Ciências Humanas e Sociais, 2014.<br>O fluxo migratório de haitianos para o Brasil teve início após o terremoto que destruiu Porto Príncipe, capital do Haiti, e arredores em 2010. Em pouco tempo a cidade de São Paulo passou a figurar como destino de parte considerável dos imigrantes que entravam no Brasil através das fronteiras amazônicas. A Missão Paz, entidade mantida pelos missionários scalabrinianos na região central de São Paulo, passou a abrigar os imigrantes desde então. O entorno desta tornou-se um local de referência para os haitianos em São Paulo. Nesta região vivem muitos imigrantes e trabalham outros tantos, sendo possível notar o surgimento de comércios co-étnicos empreendidos por imigrantes haitianos. O alto custo de vida leva parte dos imigrantes a buscar locais alternativos à região central de São Paulo, como bairros afastados e cidades da região metropolitana, como Santo André, município onde a presente pesquisa foi desenvolvida. Além do custo do aluguel mais baixo, fatores como facilidade de locação dos imóveis e meios de locomoção, são levados em consideração pelos imigrantes, sendo possível observar que as comunidades estão se formando em regiões próximas às estações de trens. Na região do Grande ABC a comunidade haitiana mais representativa localiza-se no Núcleo Ciganos, próximo à estação Utinga da Companhia Paulista de Trens Metropolitanos. O trabalho de campo realizado nesta comunidade nos levou à percepção de fenômenos comuns a diversos fluxos migratórios, bem como a apreensão de signos particulares dos haitianos evangélicos, grupo o qual nos inserimos. As redes de contato entre os haitianos estão em constante expansão, consolidando rotas migratórias diversas. Já é possível observar imigrantes que partem do Haiti diretamente para Santo André, o que não existia há até pouco tempo atrás. Reve de Brezil, em crioulo haitiano, alude ao "Sonho Brasileiro" dos haitianos; sonho este repleto de fantasias que se desfazem com a realidade cotidiana dos imigrantes que aqui chegam.<br>The migration of haitians to Brazil began after the earthquake that destroyed Port Prince, capital of Haiti, and surrounding areas in 2010. In a short time the city of São Paulo has been integrated as destination of large part of immigrants who entered in Brazil through the amazon borders. The Missão Paz, supported by the scalabrini missionaries in downtown São Paulo, has housed the immigrants since then. The surroundings of this have become a reference site for haitians. In this region many immigrants live and some of them work, it is possible to note the emergence of co-ethnics trades undertaken by haitian immigrants. The high cost of living leads the immigrants to seek alternative sites regarding to São Paulo downtown, as outer boroughs and cities of the metropolitan area, such as Santo André, the county where this research was conducted. Besides cheap rent, factors such as ease for rental property and means of transportation are taken into consideration by immigrants; it is possible to observe that communities are forming in regions close to train stations. In the Grande ABC region, the most representative haitian community are located at the Núcleo Ciganos, near Utinga station from the metropolitan train company. The fieldwork in this community led us to the perception of common phenomena to various migration flows, as well as the seizure of particular signs of evangelical haitians, group which we immersed ourselves. Contact networks among haitians are constantly expanding, consolidating several migratory routes. It is possible to observe immigrants who depart from Haiti directly to Santo André, which did not exist in a very short time ago. Reve de Brezil in Haitian Creole, alludes to the "Brazilian Dream" of Haitians; this dream full of fantasies which break with the daily reality of the immigrants who arrive here.

En adoptant une approche qualitative et pluridisciplinaire, basée sur l’étude longitudinale des circulations de la population de Deir Mqaren - un village syrien situé entre Damas et la frontière libanaise - cette thèse interroge la dimension réticulaire des mobilités humaines. A travers les récits de vie des réfugiés de cette bourgade et l’analyse de leurs parcours migratoires vers la Jordanie et l’Allemagne, elle décrypte la mécanique des flux au départ de Syrie. Cette recherche invite ainsi le lecteur à déplacer son regard vers des réseaux de lieux et d’acteurs souvent considérés comme marginaux, mais formant pourtant l’ossature des routes de l’exil reliant la Syrie au reste du globe. En plaçant la focale sur les conditions du mouvement des individus, l’intention de cette étude est à la fois de mettre en exergue les imbrications entre les migrations économiques antérieures au conflit et la logique des mouvements actuels de réfugiés ; mais aussi de montrer de manière tangible l’évolution des mécanismes relationnels permettant aux exilés d’accéder à des ressources (informations, mobilité, logement, emploi) en dépit des contraintes structurelles auxquelles ils ne cessent d’être confrontés. Les représentations (carto)graphiques élaborées dans le cadre de cette thèse visent pour leur part à mieux rendre compte du caractère mobile, instable et particulièrement labile de ces dynamiques socio-spatiales<br>In adopting a qualitative and multidisciplinary approach, based on the longitudinal study of the Deir Mqaren’s inhabitants’ circulations – a Syrian village located between Damascus and the Lebanese border – this thesis questions the “reticular” dimension of human mobility.

Thus, this research invites the reader to move his focus towards networks of places and actors often considered as being marginal, despite the fact that they form the “backbone” of the roads of exile liking Syria to the rest of the world. By placing the focal point on individuals’ conditions of movement, the intention of this study is to both highlight the continuum existing between pre-conflict economic migration and the logic of the current refugee movements; and show in a tangible way the evolution of the relational mechanisms allowing exiles to access resources (such as information, mobility, housing, employment) despite the structural constraints they are constantly facing on their way towards safe destinations. The graphic representations developed in the framework of this thesis aim to better reflect the mobile, unstable and particularly labile nature of these socio-spatial dynamics

Full textAbstract:
Cette recherche s’intéresse plus particulièrement aux espaces traversés, aux espaces d’attente, et aux espaces habités par des hommes et des femmes colombiens au cours de leur voyage migratoire vers la France et une fois qu’ils sont à Paris. La thèse repose sur une enquête ethnographique réalisée entre 2009 et 2014 en France et en Colombie. Cette enquête multi située a mis en évidence que les circulations des migrants partis de Colombie peuvent être fragmentées et interrompues ; leurs trajectoires ne sont pas linéaires et fluides. Elles sont faites de ruptures, de bifurcations et d’attentes qui échappent au contrôle des acteurs. La recherche montre que face aux contraintes externes dont ils sont dépendants, les pratiques de « débrouille » individuelles et collectives elles-mêmes imbriquées à des réseaux sociaux transnationaux, facilitent la circulation d’un pays vers l’autre et la réorientation des projets migratoires. Ces réseaux sont surtout familiaux, mais pas exclusivement. Ils peuvent être constitués d’étudiants de troisième cycle comme de réfugiés, de passeurs (« tramitadores ») ou de voyageurs qui cherchent à traverser les frontières et se rapprochent de manière aléatoire et ponctuelle (dans une zone d’attente ; dans un foyer à Paris). Les enquêtes ont montré également que les représentations et les pratiques sociales des migrants entraînent des mutations éphémères ou durables des espaces parisiens où ils se retrouvent selon des modalités diverses. La culture culinaire, par exemple, qui est à la base d’une économie formelle et informelle, se matérialise dans des espaces urbains quotidiens (restaurants et épiceries du quartier Père Lachaise ou des Batignolles), ainsi que dans des lieux où se déroulent des événements sporadiques (célébrations politiques, rencontres sportives au bois de Vincennes). Les analyses confirment le rôle notable que jouent les migrants dans les transformations morphologiques d’un quartier, la tonalité d’une rue ou dans la finalité d’un lieu de loisir ; de ce point de vue l’anthropologue peut les considérer comme les architectes de leurs paysages migratoires<br>This thesis studies the crossed spaces, the waiting spaces and the spaces inhabited by Colombian men and women throughout their migratory journey to France, and once they are in Paris. The thesis is supported by an ethnographic research between 2009 and 2014 in France and Colombia. This multi-sited ethnography showed that the circulation of migrants who have left Colombia can be fragmented and interrupted. The trajectories of migrants are far from being linear and fluid; they are crossed by ruptures, bifurcations and expectations that escape the control of the actors. The research shows that in face of external difficulties, the individual and collective practice of "rebusque" (resourcefulness) imbricated in transnational social networks, favor the reorientation of migratory projects and the circulation of actors from one side of the Atlantic to the other. These networks are usually made up of family members, but also of graduate students, refugees, passers-by (“tramitadores”), or travelers who try to cross borders and meet in a rapid and random manner. The research also showed that the representations and social practices of the migrants produce ephemeral or lasting mutations of the Parisian spaces. The culinary culture, for example, on which rests a formal and informal economy, is materialized in everyday urban spaces (restaurants and shops in the Père Lachaise or Batignolles neighborhoods), as well as sporadic events (political celebrations, sports tournaments in Vincennes forest). The analysis confirms the major role of migrants in the morphological transformations of a neighborhood, in the aspect of a street, or in the uses of a place of entertainment; from this point of view, the anthropologist can consider them as architects of their migratory landscapes<br>Este trabajo se interesa en los espacios recorridos, los espacios de espera y los espacios habitados por hombres y mujeres colombianos a lo largo de su viaje migratorio hacia Francia, y una vez están en París. La tesis se apoya en una investigación etnográfica realizada entre 2009 y 2014 en Francia y en Colombia. Esta etnografía multisituada puso en evidencia que las circulaciones de los y las migrantes que han dejado Colombia pueden ser fragmentadas e interrumpidas. Las trayectorias de los y las migrantes, lejos de ser lineales y fluidas, están atravesadas por rupturas, bifurcaciones y esperas que escapan al control de los actores. La investigación muestra que frente a dificultades externas, las prácticas de “rebusque” individuales y colectivas imbricadas en redes sociales transnacionales, favorecen la reorientación de los proyectos migratorios y la circulación de los actores de un lado al otro del Atlántico. Estas redes son principalmente familiares, pero también se constituyen alrededor de estudiantes de postgrado, de refugiados, de paseros, o de viajeros que intentan cruzar las fronteras y se encuentran de manera puntual y aleatoria. La investigación también mostró que las representaciones y las prácticas sociales de los y las migrantes producen mutaciones efímeras o durables de los espacios parisinos. La cultura culinaria, por ejemplo, sobre la cual reposa una economía formal e informal, se materializa en espacios urbanos cotidianos (restaurantes y tiendas de los barrios Père Lachaise o Batignolles), así como en aquellos donde se desarrollan eventos esporádicos (celebraciones políticas, torneos deportivos en el bosque de Vincennes). Los análisis confirman el rol mayor que juegan los y las migrantes en las transformaciones morfológicas de un barrio, en el aspecto de una calle, o en los usos de un lugar de esparcimiento; desde ese punto de visa la antropología puede considerarlos como arquitectos y arquitectas de sus paisajes migratorios

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior<br>The rural youth classically integrated the internal migratory processes, but recently they have also
constituting international. So, the study analyzed how rural young people from a family farming
experienced contemporary international migration in its various phases, which were emigration, travel,
immigration and return. Of a qualitative nature, the study was conducted in the case study format and held
in the city of Itapuranga, state of Goiás, Brazil. Data were collected through 09 interviews with social
workers who have experienced international migration in their youth. Although adults at the time of the
interviews, these used their memories to rebuild international migration experiences as rural youth. Were
also interviewed 17 key-informants and other data collected through observation, documentary research
and literature research. In Itapuranga, there was the existence of a culture of migration on family farming,
being common migration in this context. This culture interfered on the socialization of rural youth,
expanding their social horizons of "local" to "global". Many socioeconomic conditions favored these
international emigration, especially in the early XXI century, involving the crisis in family farming, few
alternatives for employment and education in the region, devaluation of national currency and
establishment of international migration networks. So, were built international migration projects in search
of social reproduction and autonomy. These international migration were undocumented and happened
through different routes: legal route, with visas and directed the nations located in the Americas and
Europe, carried out air; and illegal route, without visas and intended only to the United States, with a
segment of the crossing by land in Mexico. In the latter, was intense participation of the immigration
industry, increasing the risks involved in travel The main destinations of migrants consisted in the United
States and European nations. The immigration stood out because of the cultural and environmental
strangeness abroad and migrant vulnerability at work, inserted in low-paid and exhaustive services with the
aim of accumulate money, including prostitution. The migrants also experienced poor living conditions and
could not devote time to education. The immigration was experienced in loneliness, because of the
embarrassing relationships with foreign and other Brazilian immigrants, stressing the longing and
communication with family and friends in Brazil. Most returned to accumulate a significant amount of
money, encouraged by the international economic crisis, stabilization of the Brazilian economy, the real
appreciation, longing families and advancement of their ages, especially in the middle of the first decade of
XXI century. The returns also resignified the links of migrants to rural areas and family farming, favoring
the emergence of new ruralities. Also, became hybrid identities of these migrants and marked the end of the
youth of them. So, it was concluded that international migration among rural young people from a family
farming of Itapuranga were not unidirectional, being characterized by comings and goings, showing
different ways to experience the youth in rural areas. It was concluded, also, the need for public c policies
and extension actions involving the singularities of these international migrants.<br>Os jovens rurais classicamente integraram os processos migratórios internos, mas recentemente os mesmos
vêm constituindo também os internacionais. Assim, o estudo analisou como os jovens rurais oriundos da
agricultura familiar vivenciaram as migrações internacionais contemporâneas em suas variadas fases, sendo
elas emigração, viagem, imigração e retorno. De natureza qualitativa, o estudo foi conduzido no formato de
estudo de caso e realizado no município de Itapuranga, estado de Goiás, Brasil. Coletaram-se dados através
de 09 entrevistas com agentes sociais que vivenciaram migrações internacionais em sua juventude. Embora
adultos no momento das entrevistas, esses recorreram às suas memórias para reconstruir as vivências
migratórias internacionais como jovens rurais. Também foram entrevistados 17 informantes-chave e
coletados outros dados através de observação, pesquisa documental e pesquisa bibliográfica. Em
Itapuranga, constatou-se a existência de uma cultura de migração na agricultura familiar, sendo as
migrações comuns nesse contexto. Essa cultura interferiu sobre as socializações dos jovens rurais,
expandindo seus horizontes sociais do local para o global . Inúmeras condicionantes socioeconômicas
favoreceram essas emigrações internacionais, sobretudo no início do século XXI, envolvendo a crise na
agricultura familiar, escassas alternativas de trabalho e educação na região, desvalorização da moeda
nacional e constituição de redes migratórias internacionais. Assim, foram construídos projetos migratórios
internacionais em busca de reprodução social e autonomia. Essas migrações internacionais foram
indocumentadas e aconteceram através de rotas distintas: rota legal, com vistos e direcionada a nações
situadas no continente americano e europeu, realizada via aérea; e rota ilegal, sem vistos e direcionada
somente aos Estados Unidos, com um segmento da travessia via terrestre no México. Nessa última, foi
intensa a participação da indústria de imigração, aumentando os riscos nas viagens. Os principais destinos
dos migrantes consistiram nos Estados Unidos e nações europeias. A imigração se destacou em virtude dos
estranhamentos culturais e ambientais no exterior e da vulnerabilidade dos migrantes no trabalho, inseridos
em serviços mal remunerados e exaustivos com o intuito de acumular dinheiro, inclusive na prostituição.
Os migrantes também vivenciaram condições de moradia precárias e não conseguiram dedicar tempo à
educação. A imigração foi vivenciada na solidão em razão dos embaraçosos relacionamentos com os
estrangeiros e com outros imigrantes brasileiros, acentuando a saudade e a comunicação com os familiares
e amigos no Brasil. A maioria retornou ao acumular uma quantia significativa de dinheiro, incentivados
pela crise econômica internacional, estabilização da economia brasileira, valorização do real, saudade das
famílias e avanço de suas idades, principalmente em meados da primeira década do século XXI. Os
retornos também ressignificaram os vínculos dos migrantes com o meio rural e a agricultura familiar,
favorecendo o surgimento de novas ruralidades. Além disso, tornaram híbridas as identidades desses
migrantes e assinalaram o fim da juventude dos mesmos. Assim, concluiu-se que as migrações
internacionais entre jovens rurais oriundos da agricultura familiar de Itapuranga não foram unidirecionais,
caracterizadas por idas e vindas, mostrando maneiras diferentes de vivenciar a juventude nas áreas rurais.
Concluiu-se, também, a necessidade de políticas públicas e ações extensionistas relacionadas com as
singularidades desses migrantes internacionais.

The interdisciplinary approach adopted in this thesis allowed to examine the question under sociological and communicational point of view by taking into account the political and geographical aspects. The migration of African sub-Saharan towards Turkey is associated with the reinforcement of controls at the external border, particularly in Europe, which favors the appereance of new migratory roads and new transit hubs. This reinforcement of border controls leads the migrants to reformulate their migration project. In this context of irregular migrations, this thesis intends to understand how the ICTs are appropriated by migrants and what is the role of these technologies in the construction and the maintenance of the social networks

Cette thèse analyse la politique de migration lors du recrutement d'immigrants qualifiés, menée par la province canadienne du Québec et la communauté brésilienne dans cette province francophone. Pour cela, le concept de diaspora a été utilisé comme modèle analytique de la formation de cette communauté d'immigrés dans une région d'installation non traditionnelle. Tout d'abord, ce travail présente l'histoire de cette province canadienne et le développement de la thématique migratoire et linguistique et le rôle des politiques de migration qui ont conduit à l'autonomie de la province dans le recrutement et la sélection de ses immigrants du volet économique en employant le système des points. Ensuite, les principales caractéristiques des communautés brésiliennes dans les principaux pays d'installation sont abordées afin de présenter la question de l'émigration brésilienne comme un phénomène contemporain. Il est démontré comment, depuis les années 1980 ce mouvement, auparavant résiduel, s'est répandu dans la culture brésilienne. Ensuite, est présenté le concept de diaspora afin de statuer sur l'émigration brésilienne comme une diaspora. Ultérieurement, ce travail présente, analyse et traite de la migration des Brésiliens sous ce prisme à travers des entretiens semi-directifs, dont les moyens institutionnels et formels, ainsi que les non institutionnels et informels d'être ici et là-bas sont largement employés. Il met en évidence le rôle des réseaux sociaux virtuels dans le processus,dans leur trajectoire migratoire et dans la formation de la communauté.

For this, the concept of diaspora has been used as an analytical model of the formation of the immigrant community in a non-traditional installation area. Initially this work presents the history of this province and the development of thematic and linguistic migration and the role of migration policies that led to the autonomy of the province in the recruitment and selection of its economic immigrants using the points system. Then, the main characteristics of Brazilian communities in major country of installation are presented in order to place the issue of Brazilian emigration as a contemporary phenomenon. It is shown how, since the 1980s, this movement, previously residual, has become so prevalent in Brazilian culture. Then, the concept of diaspora is introduced to show the Brazilian emigration as a diaspora. Subsequently, this work presents, analyzes and discusses the migration of Brazilians under this prism through semi-structured interviews, with institutional and formal means, as well as non-institutional and informal to be here and there that are widely used. It highlights the role of virtual social networks in the process, in their migration history and the formation of community. It is shown that these Brazilians, when leaving their country, were looking for a certain quality of life and social guarantees that in Brazil they believed to be excluded<br>Esta tese analisa a política migratória de recrutamento de imigrantes qualificados conduzida pela província canadense do Québec e a comunidade brasileira nessa província francófona.

Primeiramente, este trabalho apresenta a história desta província e do desenvolvimento da temática migratória e linguística e o papel das políticas de migração que levaram à autonomia da província no recrutamento e na seleção de seus imigrantes da categoria econômica através do sistema de pontos. Em seguida, as principais características das comunidades brasileiras nos principais países de instalação foram abordadas a fim de apresentar a questão da emigração brasileira como um fenômeno contemporâneo. É mostrado como, desde os anos 1980, este movimento, até então residual, se difundiu na cultura brasileira. Em seguida, é introduzido o conceito de diáspora afim de situarmos a emigração brasileira como uma diáspora. Posteriormente, este trabalho apresenta, analisa e discute a migração de brasileiros sob esse prisma por meio de entrevistas semi-estruturadas, cujos meios institucionais e formais, bem como não institucionais e informais para estar aqui e estar lá são amplamente utilizados. Ademais, destaca-se o papel das redes sociais virtuais no processo de imigração, na trajetória migratória e na formação dessa comunidade imigrante. É mostrado que esses brasileiros, quando deixaram o seu país, estavam à procura de certa qualidade de vida e de garantias sociais que eles acreditavam ser sido excluídos no Brasil

Full textAbstract:
This chapter highlights the multiple ways in which Burgos's legacy extends into visual culture and El Barrio neighborhood in East Harlem. In the act of remembering Julia de Burgos, visual artists are less concerned with finding the “true” Julia; rather, they create sites of memory that are at once collective and individual. As Burgos emerged as an icon specific to New York Latino/a culture, remembering her became one of the memory circuits mapping the migratory routes of New York Latino/a cosmopolitan networks. The chapter then charts the course of Burgos's iconography, mapping the migratory trajectories and circulation of her influence from New York to Puerto Rico and the Dominican Republic and consequently offering insight into New York Latino/a cultural production.

This chapter will explore how children experienced a sense of community and family within the context of migration, focusing on case studies from the nineteenth century and the Viking Age. In particular, the chapter will look at two main migratory contexts: transnational and internal migration. There has been extensive research on migration in diverse contexts and time periods by archaeologists, but the experiences of children of migration have largely been unexplored. Analysis of recent migrations, principally by social scientists, has highlighted the distinctive experiences that children may have of migration, and revealed that children are often important mediators of the ensuing cultural interaction and assimilation, being particularly socially adept at extending adult social networks in new settings. Children can, indeed, be shown to shape the migratory experience in fundamental ways.

Full textAbstract:
During the nineteenth century, Britain maintained a complex network of garrisons to manage its global empire. While these bases helped the British project power and secure trade routes, they served more than just a strategic purpose. During their tours abroad, many British officers engaged in formal and informal scientific research. In this ambitious history of ornithology and empire, Red Coats and Wild Birds tracks British officers as they moved around the world, just as migratory birds traversed borders from season to season. The book examines the lives, writings, and collections of a number of ornithologist-officers, arguing that the transnational encounters between military men and birds simultaneously shaped military strategy, ideas about race and masculinity, and conceptions of the British Empire. Collecting specimens and tracking migratory bird patterns enabled these men to map the British Empire and the world and therefore to exert imagined control over it. Through its examination of the influence of bird watching on military science and soldiers' contributions to ornithology, Red Coats and Wild Birds remaps empire, nature, and scientific inquiry in the nineteenth-century world.

Full textAbstract:
This article discusses sociocultural and theological aspects related to space and place for Christian migrants and Pentecostal migrant churches in Norway. The article addresses how Christian migrants and migrant congregations relate to and produce dimensions of place and space within their migratory contexts, drawing from contextual examples and theoretical perspectives on space and place. Thus, spatial perspectives provide frameworks for discussing issues of belonging, religious discourses, and spirituality with regard to the migrant communities themselves, in the wider religious landscape, and in society. In particular, we ask how experiences of spatial and social constraints help shed light on how migrants and migrant churches seek to make home in new contexts. This also relates to how these migrants and churches navigate within the translocal, symbolic and virtual landscapes of Pentecostal transnational networks. Finally, the article addresses spatial dimensions of these churches and networks’ aims to bring about spiritual and societal transformation.

Full textAbstract:
Cell migration is fundamental to a wide range of biological and physiological functions including: wound healing, immune defense, cancer metastasis, as well as the formation and development of biological structures such as vascular and neural networks. In these diverse processes, cell migration is influenced by a broad set of external mechanical and biochemical cues, particularly the presence of (time dependent) spatial gradients of soluble chemoattractants in the extracellular domain. Many biological models have been proposed to explain the mechanisms leading to the migratory response of cells as a function of these external cues. Based on such models, here we propose approaches to controlling the chemotactic response of eukaryotic cells by modulating their micro-environments in vitro (for example, using a microfluidic chemotaxis chamber). By explicitly modeling i) chemoattractant-receptor binding kinetics, ii) diffusion dynamics in the extracellular domain, and iii) the chemotactic response of cells, models for the migration processes arise. Based on those models, optimal control formulations are derived. We present simulation results, and suggest experimental approaches to controlling cellular motility in vitro, which can be used as a basis for cellular manipulation and control.

Full textAbstract:
Hakka emigration has created many smaller communities worldwide; where some groups continued their migratory journey. One such example is the Hakkas, who first migrated to Calcutta and then moved on to Vienna and Toronto, clustering in a close-knit social network. In various sessions, Viennese Hakkas of all age groups were interviewed for their lifestories and linguistic practices. (a) The linguistic competence of the migrants includes Hakka, English and Indian (Hindi, Ben¬gali) but often rather little German; Hakka is important at the workplace (Chinese restaurants) and is transmitted in families; Indian helps establish professional relationships with Indian migrants. (b) The social network is rather closed to Hakka friends from Calcutta or from other places. All Hakkas closely cooperate and usually have only few outside contacts. They consider Calcutta as their old homeland to which they return for Chinese New Year. (c) The younger generation consists of weak speakers of Hakka who are fully integrated into Austrian culture, but also maintain contacts to Toronto and love to visit friends and family in India. To conclude, the Indian Hakkas of Vienna are an interesting example of a two-step migration which first converted some Chinese into Indians, and then planted this Indian subgroup into Europe.

Full textAbstract:
Abstract Hydrocarbon exploration continues to venture into new avenues. This paper elaborates the 3D geomechanical study carried out to identify sweet spots in Deccan Trap Basalts in depth ranging from 500m-1100m in Cambay basin field of India. The main challenge is wide variation in the rock mechanical properties and stress profiles along various azimuths resulting from different tectonic incidents over the geological ages. Several drilling complications and held ups during electro logging in highly deviated wells are also reported. The normal fault tectonic framework has the imprint of two sets of faults viz., NNW-SSE and ENE-WSW. Deccan Trap acts as reservoirs due to the presence of connected open fracture network and to assess the potential reserves a comprehensive 3D Critically stressed fracture analysis has been performed using 3D numerical simulation-based rock properties, in-situ stress and seismic data. Open hole geophysical logs like sonic dipole and borehole images have been used to estimate rock mechanical properties and stress profiles in 18 key wells. Available core data of Basalt in the area have been used for dynamic to static rock properties estimation along with available published literature data. Critically stressed fracture analysis using 1D MEM outputs and dips dataset has been performed at well scale to history match production logging and testing results of 23 wells located in different fault blocks. 3D stress model has been built using plasticity model while taking into account faults and fracture sets. Utilizing 3D Geomechanical properties and Discrete fracture network model, critically stressed fracture sets have been identified across the field with slip tolerance and effective drawdown pressures. The study suggests that structurally high locations are good producers if seals are present above Trap. Sub-horizontal fractures have a higher closing tendency with decline in pressure in layers with SHmax&gt;SHmin&gt;Sv inside stiff Trap layer. There is variation of slip tolerance in the range of 0.2-1.4 in fracture sets which indicates slip tendency to be varying both vertically and laterally. Faults with ENE-WSW strike seem to be fluid migratory conduits and their intersection with NNW-SSE discontinuities are the areas where fracture sets have a higher slip tendency. Most of the producing layers are within 25m-55m of Trap with water being encountered at deeper depth intervals. These are mostly weathered fractured layers within the trap. The stress map suggests rotation of the maximum horizontal stress azimuth from NW to E which also affects fracture intensity in the field. Few fracture sets have tendency to be slip prone even with depletion up to 300psi-800psi while others will require stimulation or acid clean up job. Eight exploration wells drilled based on the study have shown good flow rate on initial well testing in the area providing validation to the study.
