The environment affects our health, livelihoods, and the social and political institutions within which we interact. Indeed, nearly a quarter of the global disease burden is attributed to environmental factors, and many of these factors are exacerbated by global climate change. Thus, the central research question of this dissertation is: How do people cope with and adapt to uncertainty, complexity, and change of environmental and health conditions? Specifically, I ask how institutional factors, risk aversion, and behaviors affect environmental health outcomes. I further assess the role of social capital in climate adaptation, and specifically compare individual and collective adaptation. I then analyze how policy develops accounting for both adaptation to the effects of climate and mitigation of climate-changing emissions. In order to empirically test the relationships between these variables at multiple levels, I combine multiple methods, including semi-structured interviews, surveys, and field experiments, along with health and water quality data. This dissertation uses the case of Ethiopia, Africa’s second-most populous nation, which has a large rural population and is considered very vulnerable to climate change. My fieldwork included interviews and institutional data collection at the national level, and a three-year study (2012-2014) of approximately 400 households in 20 villages in the Ethiopian Rift Valley. I evaluate the theoretical relationships between households, communities, and government in the process of adaptation to environmental stresses. Through my analyses, I demonstrate that water source choice varies by individual risk aversion and institutional context, which ultimately has implications for environmental health outcomes. I show that qualitative measures of trust predict cooperation in adaptation, consistent with social capital theory, but that measures of trust are negatively related with private adaptation by the individual. Finally, I describe how Ethiopia had some unique characteristics, significantly reinforced by international actors, that led to the development of an extensive climate policy, and yet with some challenges remaining for implementation. These results suggest a potential for adaptation through the interactions among individuals, communities, and government in the search for transformative processes when confronting environmental threats and climate change.

Transnational governance has been advanced as a viable option for regulating commodities produced in emerging economies—where incapable or unwilling states may undersupply institutions requisite for overseeing supply chains consistent with the quality, safety, environmental, or social standards demanded by the global marketplace. Producers from these jurisdictions, otherwise left with few venues for securing market access and price premiums, ostensibly benefit from whatever pathways transnational actors offer to minimize barriers to entry—including voluntary certification for compliance with a panoply of public and private rules, such as those promulgated by NGOs like the Fair Trade Federation or multinational retailers like Wal-Mart. Yet, such transnational “sustainability” governance may neither be effective nor desirable. Regulatory schemes, like third-party certification, often privilege the interests of primary architects and beneficiaries—private business associations, governments, NGOs, and consumers in the global North—over regulatory targets—producers in the global South. Rather than engaging with the international marketplace via imported and externally-driven schemes, some producer groups are instead challenging existing rules and innovating homegrown institutions. These alternatives to commercialization adopt some institutional characteristics of their transnational counterparts yet deliver benefits in a manner more aligned with the needs of producers. Drawing on original empirical cases from Nicaragua and Mexico, this dissertation examines the role of domestic institutional alternatives to transnational governance in enhancing market access, environmental quality and rural livelihoods within producer communities. Unlike the more technocratic and expert-driven approaches characteristic of mainstream governance efforts, these local regulatory institutions build upon the social capital, indigenous identity, “ancestral” knowledge, and human assets of producer communities as new sources of power and legitimacy in governing agricultural commodities.

Alors que les activités anthropiques font basculer de nombreux écosystèmes vers des régimes fonctionnels différents, la résilience des systèmes socio-écologiques devient un problème pressant. Des acteurs locaux, impliqués dans une grande diversité de groupes — allant d’initiatives locales et indépendantes à de grandes institutions formelles — peuvent agir sur ces questions en collaborant au développement, à la promotion ou à l’implantation de pratiques plus en accord avec ce que l’environnement peut fournir. De ces collaborations répétées émergent des réseaux complexes, et il a été montré que la topologie de ces réseaux peut améliorer la résilience des systèmes socio-écologiques (SSÉ) auxquels ils participent. La topologie des réseaux d’acteurs favorisant la résilience de leur SSÉ est caractérisée par une combinaison de plusieurs facteurs : la structure doit être modulaire afin d’aider les différents groupes à développer et proposer des solutions à la fois plus innovantes (en réduisant l’homogénéisation du réseau), et plus proches de leurs intérêts propres ; elle doit être bien connectée et facilement synchronisable afin de faciliter les consensus, d’augmenter le capital social, ainsi que la capacité d’apprentissage ; enfin, elle doit être robuste, afin d’éviter que les deux premières caractéristiques ne souffrent du retrait volontaire ou de la mise à l’écart de certains acteurs. Ces caractéristiques, qui sont relativement intuitives à la fois conceptuellement et dans leur application mathématique, sont souvent employées séparément pour analyser les qualités structurales de réseaux d’acteurs empiriques. Cependant, certaines sont, par nature, incompatibles entre elles. Par exemple, le degré de modularité d’un réseau ne peut pas augmenter au même rythme que sa connectivité, et cette dernière ne peut pas être améliorée tout en améliorant sa robustesse. Cet obstacle rend difficile la création d’une mesure globale, car le niveau auquel le réseau des acteurs contribue à améliorer la résilience du SSÉ ne peut pas être la simple addition des caractéristiques citées, mais plutôt le résultat d’un compromis subtil entre celles-ci. Le travail présenté ici a pour objectifs (1), d’explorer les compromis entre ces caractéristiques ; (2) de proposer une mesure du degré auquel un réseau empirique d’acteurs contribue à la résilience de son SSÉ ; et (3) d’analyser un réseau empirique à la lumière, entre autres, de ces qualités structurales. Cette thèse s’articule autour d’une introduction et de quatre chapitres numérotés de 2 à 5. Le chapitre 2 est une revue de la littérature sur la résilience des SSÉ. Il identifie une série de caractéristiques structurales (ainsi que les mesures de réseaux qui leur correspondent) liées à l’amélioration de la résilience dans les SSÉ. Le chapitre 3 est une étude de cas sur la péninsule d’Eyre, une région rurale d’Australie-Méridionale où l’occupation du sol, ainsi que les changements climatiques, contribuent à l’érosion de la biodiversité. Pour cette étude de cas, des travaux de terrain ont été effectués en 2010 et 2011 durant lesquels une série d’entrevues a permis de créer une liste des acteurs de la cogestion de la biodiversité sur la péninsule. Les données collectées ont été utilisées pour le développement d’un questionnaire en ligne permettant de documenter les interactions entre ces acteurs. Ces deux étapes ont permis la reconstitution d’un réseau pondéré et dirigé de 129 acteurs individuels et 1180 relations. Le chapitre 4 décrit une méthodologie pour mesurer le degré auquel un réseau d’acteurs participe à la résilience du SSÉ dans lequel il est inclus. La méthode s’articule en deux étapes : premièrement, un algorithme d’optimisation (recuit simulé) est utilisé pour fabriquer un archétype semi-aléatoire correspondant à un compromis entre des niveaux élevés de modularité, de connectivité et de robustesse. Deuxièmement, un réseau empirique (comme celui de la péninsule d’Eyre) est comparé au réseau archétypique par le biais d’une mesure de distance structurelle. Plus la distance est courte, et plus le réseau empirique est proche de sa configuration optimale. La cinquième et dernier chapitre est une amélioration de l’algorithme de recuit simulé utilisé dans le chapitre 4. Comme il est d’usage pour ce genre d’algorithmes, le recuit simulé utilisé projetait les dimensions du problème multiobjectif dans une seule dimension (sous la forme d’une moyenne pondérée). Si cette technique donne de très bons résultats ponctuellement, elle n’autorise la production que d’une seule solution parmi la multitude de compromis possibles entre les différents objectifs. Afin de mieux explorer ces compromis, nous proposons un algorithme de recuit simulé multiobjectifs qui, plutôt que d’optimiser une seule solution, optimise une surface multidimensionnelle de solutions. Cette étude, qui se concentre sur la partie sociale des systèmes socio-écologiques, améliore notre compréhension des structures actorielles qui contribuent à la résilience des SSÉ. Elle montre que si certaines caractéristiques profitables à la résilience sont incompatibles (modularité et connectivité, ou — dans une moindre mesure — connectivité et robustesse), d’autres sont plus facilement conciliables (connectivité et synchronisabilité, ou — dans une moindre mesure — modularité et robustesse). Elle fournit également une méthode intuitive pour mesurer quantitativement des réseaux d’acteurs empiriques, et ouvre ainsi la voie vers, par exemple, des comparaisons d’études de cas, ou des suivis — dans le temps — de réseaux d’acteurs. De plus, cette thèse inclut une étude de cas qui fait la lumière sur l’importance de certains groupes institutionnels pour la coordination des collaborations et des échanges de connaissances entre des acteurs aux intérêts potentiellement divergents.

Sampling may promote prolonged engagement in sport by limiting physical injuries (Fraser-Thomas et al., 2005). Overtraining injuries are a concern for young athletes who specialize in one sport and engage in high volumes of deliberate practice (Hollander, Meyers, & Leunes, 1995; Law, Côté, & Ericsson, 2007). For instance, young gymnasts who practice for over 16 hours a week have been shown to have higher incidences of back injuries (Goldstein, Berger, Windier, & Jackson, 1991). A sampling approach in child-controlled play (e.g. deliberate play) rather than highly adult-controlled practice (e.g. deliberate practice) has been proposed as a strategy to limit overuse and other sport-related injuries (Micheli, Glassman, & Klein, 2000). In summary, sampling may protect against sport attrition by limiting sport related injuries and allowing children to have early experiences in sport that are enjoyable. Psychosocial Benefits of Sampling Only a small percentage of children who participate in school sports ever become elite athletes. Therefore, the psychosocial outcomes of sport participation are particularly important to consider. Recent studies with youth between the ages of 11 to 17 have found that those who are involved in a variety of extracurricular activities (e.g. sports, volunteer, arts) score more favourably on outcome measures such as Grade Point Average (GPA; Fredricks & Eccles, 2006a) and positive peer relationships (Fredricks & Eccles, 2006b) than youth who participate in fewer activities. These patterns are thought to exist due to each extracurricular activity bringing its own distinct pattern of socialization experiences that reinforce certain behaviours and/or teach various skills (Fredricks & Eccles, 2006b; Rose-Krasnor, Bussen, Willoughby, & Chambers, 2006). This contention is corroborated by studies of children and youths' experiences in extracurricular activities indicating that youth have unique experiences in each activity that contribute to their development (Hansen, Larson, & Dworkin, 2003; Larson, Hansen, & Moneta, 2006). This has led Wilkes and Côté (2007) to propose that children who sample different activities (through their own choice or by virtue of parental direction), have a greater chance of developing the following five developmental outcomes compared to children who specialize in one activity: 1) life skills, 2) prosocial behaviour, 3) healthy identity, 4) diverse peer groups and 5) social capital.

Background and Objectives: Mobility limitations are a prevalent issue in older adult populations, and an important determinant of disability and mortality. Neighborhood conditions are key determinants of mobility and perception of safety may be one such determinant. Women have more mobility limitations than men, a phenomenon known as the gender mobility gap. The objective of this work was to validate a measure of perception of safety, examine the relationship between neighborhood perception of safety and mobility limitations in seniors, and explore if these effects vary by gender. Methods: This study was cross-sectional, using questionnaire data collected from community-dwelling older adults from four sites in Canada, Colombia, and Brazil. The exposure variable was the neighborhood aggregated Perception of Safety (PoS) scale, derived from the Physical and Social Disorder (PSD) scale by Sampson and Raudenbush. Its construct validity was verified using factor analyses and correlation with similar measures. The Mobility Assessment Tool – short form (MAT-sf), a video-based measure validated cross-culturally in the studied populations, was used to assess mobility limitations. Based on theoretical models, covariates were included in the analysis, both at the neighborhood level (SES, social capital, and built environment) and the individual level (age, gender, education, income, chronic illnesses, depression, cognitive function, BMI, and social participation). Multilevel modeling was used in order to account for neighborhood clustering. Gender specific analyses were carried out. SAS and M-plus were used in this study. Results: PoS was validated across all sites. It loaded in a single factor, after excluding two items, with a Cronbach α value of approximately 0.86. Mobility limitations were present in 22.08% of the sample, 16.32% among men and 27.41% among women. Neighborhood perception of safety was significantly associated with mobility limitations when controlling for all covariates, with an OR of 0.84 (CI 95%: 0.73-0.96), indicating lower odds of having mobility limitations as neighborhood perception of safety improves. Gender did not affect this relationship despite women being more likely to have mobility limitations and live in neighborhoods with poor perception of safety. Conclusion: Neighborhood perception of safety affected the prevalence of mobility limitations in older adults in the studied population.

The paper reports on a study of design studio culture from a student perspective. Learning in design studio culture has been theorised variously as a signature pedagogy emulating professional practice models, as a community of practice and as a form of problem-based learning, all largely based on the study of teaching events in studio. The focus of this research has extended beyond formally recognized activities to encompass the student’s experience of their social and community networks, working places and study set-ups, to examine how these have contributed to studio culture and how there have been supported by studio teaching. Semi-structured interviews with final year undergraduate students of architecture formed the basis of the study using an interpretivist approach informed by Actor-network theory, with studio culture featured as the focal actor, enrolling students and engaging with other actors, together constituting an actor-network of studio culture. The other actors included social community patterns and activities; the numerous working spaces (including but not limited to the studio space itself); the equipment, tools of trade and material pre-requisites for working; the portfolio enrolling the other actors to produce work for it; and the various formal and informal events associated with the course itself. Studio culture is a highly charged social arena: The question is how, and in particular, which aspects of it support learning? Theoretical models of situated learning and communities of practice models have informed the analysis, with Bourdieu’s theory of practice, and his interrelated concepts of habitus, field and capital providing a means of relating individually acquired habits and modes of working to social contexts. Bourdieu’s model of habitus involves the externalisation through the social realm of habits and knowledge previously internalised. It is therefore a useful model for considering whole individual learning activities; shared repertoires and practices located in the social realm. The social milieu of the studio provides a scene for the exercise and display of ‘practicing’ and the accumulation of a form of ‘practicing-capital’. This capital is a property of the social milieu rather than the space, so working or practicing in the company of others (in space and through social media) becomes a more valued aspect of studio than space or facilities alone. This practicing-capital involves the acquisition of a habitus of studio culture, with the transformation of physical practices or habits into social dispositions, acquiring social capital (driving the social milieu) and cultural capital (practicing-knowledge) in the process. The research drew on students’ experiences, and their practicing ‘getting a feel for the game’ by exploring the limits or boundaries of the field of studio culture. The research demonstrated that a notional studio community was in effect a social context for supporting learning; a range of settings to explore and test out newly internalised knowledge, demonstrate or display ideas, modes of thinking and practicing. The study presents a nuanced interpretation of how students relate to a studio culture that involves a notional community, and a developing habitus within a field of practicing that extends beyond teaching scenarios.

International migration sets in motion a range of significant transnational processes that connect countries and people. How migration interacts with development and how policies might promote and enhance such interactions have, since the turn of the millennium, gained attention on the international agenda. The recognition that transnational practices connect migrants and their families across sending and receiving societies forms part of this debate. The ways in which policy debate employs and understands transnational family ties nevertheless remain underexplored. This article sets out to discern the understandings of the family in two (often intermingled) debates concerned with transnational interactions: The largely state and policydriven discourse on the potential benefits of migration on economic development, and the largely academic transnational family literature focusing on issues of care and the micro-politics of gender and generation. Emphasizing the relation between diverse migration-development dynamics and specific family positions, we ask whether an analytical point of departure in respective transnational motherhood, fatherhood or childhood is linked to emphasizing certain outcomes. We conclude by sketching important strands of inclusions and exclusions of family matters in policy discourse and suggest ways to better integrate a transnational family perspective in global migration-development policy.

Las características urbanísticas de las expansiones urbanas postindustriales desarrolladas en las últimas décadas en numerosas ciudades españolas presentan diferencias notables con las de barrios centrales y pericentrales más compactos preexistentes. Con el fin de estudiar cómo son percibidas por los ciudadanos de Vitoria-Gasteiz dichas diferencias urbanísticas, se realizaron 250 encuestas a residentes en los barrios compactos de la ciudad sobre sus preferencias entre el paisaje urbano de su barrio y el de los barrios postindustriales. Se observó que la gran mayoría de los encuestados prefirieron su compacto barrio en aspectos de sociabilidad, accesibilidad a servicios y bienestar global. Los resultados obtenidos se contrastaron con los de un estudio previo en el que una encuesta similar fue realizada a residentes en un barrio postindustrial. Se discuten las implicaciones de los resultados para desarrollar una práctica urbanística más sostenible y que integre la percepción de los usuarios de la ciudad.

In her presentation, Emmy discusses a case study where a teacher group is followed in its innovative attempt to start up a new curriculum. Searching for guidelines to facilitate knowledge-creating teacher groups, the ‘Dimensions of Social Learning (DSL) Framework’ is applied as a starting point to assess the group's social configuration. To supplement the DSL Framework towards knowledge creation, social capital and value creation theories were studied. This has resulted in an extended framework that can bring the knowledge creation of teacher groups into view.

Le but de cette thèse a consisté à comprendre les facteurs de la persévérance et de l’abandon scolaire des nouveaux arrivants haïtiens au Québec et à New York. La recension d’écrits a révélé une sous-documentation de la thématique en question. Toutefois, l’élaboration du cadre conceptuel nous a permis de mieux cerner la problématique, d’analyser et de synthétiser plusieurs approches théoriques dont les théories du rendement scolaire des immigrants (Rong et Brown, 2001 ; Warikoo et Carter, 2009 ; Xie et Greenman, 2011), l’approche bourdieusienne des capitaux (1979a, 1979b, 1980), le structuro-fonctionnalisme de Merton (1965) et le courant effets-écoles/ effets-enseignants (Crahay, 2000 ; Bressoux, 1994a). Nous avons également mis en évidence deux approches compréhensives à savoir l’interactionnisme (Weber, 1959 ; Boudon, 1979, 1994 ; Goffman, 1998 ; Garfinkel, 1967) et l’approche du rapport au savoir de l’équipe ESCOL (Rochex, 2002 ; Charlot, 2003) dans l’objectif de faire valoir le caractère relatif des conclusions d’une recherche qualitative qui priorise la subjectivité des participants dans l’analyse des faits sociaux. Dans cette recherche, nous avons interviewé onze participants à Montréal et à Brooklyn, parmi lesquels sept hommes et quatre femmes. Ils ont tous une expérience d’abandon scolaire au secondaire ou au secteur des adultes. Nous avons utilisé l’entretien semi-dirigé comme méthode de collecte d’information et l’analyse thématique est celle de l’analyse des données. L’analyse des données nous a permis de classer les informations fournies par les participants en cinq rubriques : capital économique, capital culturel, capital social, encadrement institutionnel et facteurs spécifiques. Ces cinq rubriques regroupent les facteurs de la persévérance et du décrochage scolaire évoqués par les participants de la recherche. La réalisation de cette thèse nous apporte un bon éclairage quant à notre tentative de comprendre la dynamique de l’abandon scolaire des jeunes et des jeunes adultes immigrants haïtiens de première génération au Québec et à New York, au secondaire et au secteur de l’éducation des adultes. Nous avons mis en relation les résultats de la recherche avec ceux des travaux que nous avons recensés dans la problématique et dans le cadre conceptuel de cette thèse. La synthèse de ces résultats nous a amené à faire une proposition d’éléments d’un modèle d’analyse que nous qualifions de « relance scolaire des nouveaux arrivants haïtiens au Québec et à New York ». L’analyse et la synthèse des facteurs émergents de la recherche, plus précisément des six thèmes qui composent la rubrique des facteurs spécifiques : facteurs démographiques, motivation personnelle, lacunes de base, facteurs affectifs, traits de personnalité et problèmes de comportement, nous ont permis d’élaborer un autre concept qui peut représenter une grande contribution à la persévérance scolaire des nouveaux arrivants haïtiens. Il s’agit de l’encadrement psycho-intégrationnel qui est une forme d’accompagnement dont les jeunes et les jeunes adultes nouveaux arrivants haïtiens pourront être bénéficiaires au début en vue d’un bon démarrage sur le plan socioéducatif et de leur persévérance scolaire au pays d’accueil. L’encadrement psycho-intégrationnel, consistera à mettre en relation certains faits psychologiques qui ont marqué la vie pré-migratoire des élèves jeunes et jeunes adultes d’origine haïtienne avec les faits sociaux qui peuvent influencer leur vie au pays d’accueil. C’est une forme d’assistance individuelle dont l’État, les institutions sociales d’intégration et l’école constitueront les principales structures de matérialisation. Les principaux intervenants, notamment les psychologues, les travailleurs sociaux et les anthropo-sociologues se chargeront de comprendre et d’orienter les nouveaux arrivants quant au nouveau comportement à adopter pour une meilleure évolution sur les plans socio-culturel, professionnel et économique. Mots clés : Persévérance scolaire, relance scolaire, immigrants haïtiens, première génération, nouveaux arrivants.

This piece of work consists in a study case of Crediamigo Comunidade, a product from the portfolio of Crediamigo Program of Banco do Nordeste, that uses the methodology of the Comunitary Banks in the concession of low amount loan to poor communities. The main question consists to understand how the Crediamigo Comunidade is characterized faced to the conflict of emancipatory versus liberal paradigms, that exists in the microcredit area. The main objective will analyze how the mechanisms: social capital, empowerment, formation to credit education and better conditions for economic and social issues promoted in the specific objectives of this product, before the dipute between these paradigms. The method adopted analyzed, in a longitudinal perspective, the three years of the product s existence (jun/2005 to jul 2008). Primary and secondary data made possible to identify qualitatively, emancipatory and non emancipatory attributes in the actions and results of Crediamigo Comunidade. It is concluded that the Crediamigo Comunidade works in a liberal logic of the Crediamigo Program, consequently, his focus is not in the emancipation of the poorest clients. The empowerment is individual and not communitary or Freiriano ; the social capital relations enlarges itself in its bounding and bridging ties, but not in its linkage ties, to have access to politic actors and consequently communitary strengthen. All the formation in the Crediamigo is strictly commercial. These characteristics happen by the liberal paradigm in the Crediamigo management and of all of its products, including the Crediamigo Comunidade

Groundwater is a common-pool resource that is subject to depletion in many places around the world as a result of increased use of irrigation and water-demanding cash crops. Where state capacity to control groundwater use is limited, collective action is important to increase recharge and restrict highly water-consumptive crops. We present results of field experiments in hard rock areas of Andhra Pradesh, India, to examine factors affecting groundwater use. Two nongovernmental organizations (NGOs) ran the games in communities where they were working to improve watershed and water management. Results indicate that, when the links between crop choice and groundwater depletion is made explicit, farmers can act cooperatively to address this problem. Longer NGO involvement in the villages was associated with more cooperative outcomes in the games. Individuals with more education and higher perceived community social capital played more cooperatively, but neither gender nor method of payment had a significantly effect on individual behavior. When participants could repeat the game with communication, similar crop choice patterns were observed. The games provided an entry point for discussion on the understanding of communities of the interconnectedness of groundwater use and crop choice.

In the 21st century climate change will cause a significant increase in the frequency and intensity of extreme weather events across Europe. Investigating farmers’ resilience to extreme weather events in the past can be used to establish the inherent level of resilience farmers’ will have to respond to comparable events in the future. The Welsh Marches has experienced a range of extreme weather events including: heatwaves, flooding; prolonged rainfall; and heavy snowfall. To identify the resilience of farmers in the Marches farmers’ apparent vulnerabilities, coping capacity, social capital and adaptive capacity that have been exposed in past events are discussed. Rural isolation is identified as an exacerbating factor of farming vulnerability. Yet, this is also an apparent source of resilience as farmers are found to rely on high social capital to assist each other in emergency and challenging situations during extreme weather events. The paper concludes by indicating that more localised studies are required, situated within unique farming cultures. This will enable a more complete picture of farmers’ resilience across Europe to be established.
