La plupart des écosystèmes sont aujourd'hui soumis à une pression anthropique croissante. Les études portant sur l'effet des activités humaines sur la biodiversité se multiplient mais elles se focalisent, principalement pour des raisons méthodologiques, sur un nombre restreint de groupes taxonomiques. L'originalité de ces travaux repose sur l'application d'une approche basée sur l'ADN environnemental permettant d'accéder à l'ensemble de la diversité biologique. Elle a ici été utilisée pour étudier l'impact des activités anthropiques sur les communautés biologiques et la résilience de ces dernières, à travers différentes échelles spatiales et temporelles. Dans une première partie, les communautés édaphiques, sous l'influence de diverses perturbations anthropiques, ont été caractérisées grâce à l'ADN contenu dans les sols. Ces études, réalisées dans différents milieux, mettent en évidence l'impact direct des activités humaines et leur influence sur les paramètres biotiques et abiotiques déterminant la distribution spatiale de la biodiversité des sols. La seconde partie se propose d'examiner l'impact à long terme des activités anthropiques au travers d'un exemple particulier en milieu de montagne. L'ADN contenu dans les archives sédimentaires lacustres a permis de retracer l'histoire des activités pastorales au cours de l'Holocène mais également les changements environnementaux que ceux-ci ont engendrés dans le bassin versant. L'approche mise en œuvre se révèle pertinente pour étudier à la fois les changements induits par les perturbations humaines sur les communautés et les facteurs influençant leurs dynamiques. Les résultats obtenus mettent notamment en lumière l'impact à long terme qu'exercent les activités anthropiques sur les communautés biologiques via les modifications profondes qu'elles génèrent sur les caractéristiques abiotiques du milieu. / Most ecosystems undergo an increasing anthropogenic pressure. Studies about the effects of human activities on biodiversity are proliferating but they focus on few taxonomical groups, mainly for methodological reasons. The originality of this work is based on the application of an approach based on environmental DNA that allows access to the biodiversity as a whole. It was used here to study the impact of anthropogenic activities on biological communities and the resilience of these latter, across different spatial and temporal scales. In the first part, edaphic communities under the influence of several human disturbances were characterized from soil DNA. These studies, performed in various environments, bring out the direct impact of human activities and their influence on biotic and abiotic parameters driving spatial distribution of soil biodiversity. In the second part, long-term impact of human activities was investigated through the analysis of lake sediments in the Alps. DNA from lacustrine sediments allowed to reconstruct livestock farming history over the Holocene and environmental changes that they induced in the catchment. We showed that this approach was relevant to study both changes generated by human disturbances on communities and factors driving their dynamics. Our results highlight the long-term impact of anthropogenic activities on biological communities, in relation to the alteration of environmental characteristics.

A Engenharia de Resiliência (ER) é um novo paradigma para gestão da segurança o qual, apesar de possuir uma fraca estrutura teórica, vem sendo aplicado em diversos setores. Neste contexto, este trabalho tem como objetivo a identificação de fontes de fragilidade e resiliência em empresas de táxi aéreo. Para essa identificação foram utilizados os seguintes princípios da ER: flexibilidade, consciência, aprendizagem e comprometimento da alta direção. O estudo de caso foi à estratégia de pesquisa adotada, tendo sido investigadas duas empresas de táxi aéreo de pequeno porte. O método de pesquisa envolveu as seguintes etapas: (a) caracterização da empresa sob a perspectiva de três subsistemas que compõem seu sistema sócio-técnico (social, técnico e organização do trabalho); (b) identificação dos constrangimentos e adaptações dos funcionários no desempenho de suas atividades; (c) identificação das fontes de fragilidade e resiliência a partir dos 4 princípios da ER, desdobradas em evidências empíricas conforme a literatura Os resultados mostram que 11 fontes estavam relacionadas à fragilidade da empresa A e 6 da empresa B. Da mesma forma, identificou-se 9 fontes de resiliência na empresa A e na empresa A. Em particular, o objetivo primário da empresa (lucro, no caso de uma das empresas; servir aos proprietários, no caso da outra empresa) revelou-se como uma fonte comum a todas as fontes de resiliência ou fragilidade e quase todas as fontes de resiliência constituíram de ações isoladas dos operadores, revelando a emergência dessas fontes na organização informal das empresas. / Resilience Engineering (RE) is a new safety management paradigm which, in spit of its weak theoretical structure, has been applied in many domains. In this context, this research has a main objective of identifying sources of brittleness and resilience on air taxi carriers. To accomplish this objective, this work used as base the following RE principles: flexibility, conscious, learning, top management commitment. Case study was the research strategy used, which investigated two small air taxi carriers. Research method involved the following steps: (a) air taxi carrier characterization from the tree subsystems that compose socio-technical system (social, technical, work system); (b) employees constraints and adaptations identification during the job; (c) brittleness and resilience source identification from 4 RE principles, unfolded in empirical evidences according to literature. The results show that 11 sources were related to brittleness at company A and 6 at company B. At the same way, 9 sources of resilience were identified at company A and company B. In particular, the main air taxi carrier objective (to profit, in of one them; to serve, to another one) appeared as a common to all sources of brittleness and resiliencies and almost all sources of resilience were constituted of isolated action from operators, revealing resilience source emergence from companies informal organization.

Notre thèse explore et analyse la situation psychosociale et scolaire d’adolescents victimes de maltraitances dans le cadre d’une approche comparée entre la métropole et la Guyane française. Nous avons examiné comment les apprentissages psycho-éducatifs et l’usage des discours de résilience participent à être thérapeutiques auprès de cette population à la lumière également de la dimension transculturelle (notamment l’impact de l’esclavage pour la Guyane qui reste encore aujourd’hui présent). Cela nous a conduit à mettre en évidence les facteurs individuels, sociaux, et les discours de résilience qui favorisent l'adaptation et le succès de ces jeunes, confrontés à de nombreuses adversités traumatiques de la vie. Notre thèse présente des résultats spécifiques de deux adolescents. Ils nous ont permis ensuite d’élaborer les facteurs communs (capacité d’attachement sécure à la relation, capacité à obtenir le soutien des autres, à avoir des objectifs personnels et/ou collectifs, le sentiment de gestion de ses émotions et affects, la capacité à mettre des mots, à donner du sens, à poser des choix possibles, l’aptitude à utiliser l’humour, etc.) qui corroborent le consensus des chercheurs les plus imminents sur la question même du processus de résilience. Autrement dit, le discours de résilience apparaît comme un facteur prépondérant dans le cheminement thérapeutique. Ainsi les apprentissages psycho-éducatifs et les différents types de discours permettent une manière de conjuguer l’espoir donné au sujet à s’affranchir de son passé traumatique, en lui permettant d’agir par lui-même et pour les autres, dans son présent et en l’autorisant à disposer d’un avenir qui répond à ses attentes. / Our thesis explores and analyses the psychosocial and school situation of teenager victims of abuse in the context of a comparative approach between continental France and French Guyana. We studied how the psycho-educational learnings and the use of resilience speeches be involved as therapeutic treatment for these victims, while considering the cross-cultural dimension (including the impact of slavery in French Guyana, which is still on today ). With regard to our approach, our results enabled us to develop the common factors (ability of safe attachment to the relationship, ability to get the support from others, ability to have personal and/or collective goals, feeling of self-managing their emotions and affects, ability to put words, to make sense, to define possible choices, to use humour, etc.) that corroborate the consensus of the most imminent researchers on the very issue of the resilience process. In light of our results, the psycho-educational learnings and various types of speeches contribute to being critical protective factors, allowing the subject to resist the trauma and to run a therapeutic approach towards the process of resilience. The uniqueness of our research, that is part of a not investigated yet dimension, could open preventive tracks to improve practice and care, and, therefore, promote the resilience of both the individuals, who need to be accompanied, and the community, given the traumatic events experienced in Guyana, especially considering the printed marks left by slavery.

Le concept de résilience a été adopté dans le langage et les pratiques de l’urbanisation planétaire, dont le modèle dominant est la planification. La théorie de la résilience est cependant critiquée, notamment pour sa difficulté à mener à des résultats prévisibles, ou pour sa récupération par les approches les plus néolibérales de cette planification. Cette thèse montre qu’elle peut aussi être un point de départ pour questionner le modèle dominant et ouvrir à d’autres manières d’appréhender, théoriser et concevoir l’urbain. Elle développe comment la théorie de la résilience urbaine peut se fonder sur un cadre conceptuel spécifique, dont les critères permettent d'orienter des choix lors d’une mise en projet. La recherche débute avec le corpus qui s’est structuré en écologie, qui a ouvert à une théorie de la résilience dans l’urbain, et en développe les singularités. Etant donné que le modèle dominant entretient un brouillage des repères, elle emprunte une méthode d’analyse métaphorique, transportant donc la théorisation en dehors des cadres de celui-ci. Elle propose pour cela un concept, celui de « piraterie urbaine», comme art de la mise en projet de la résilience. La métaphore de la piraterie est construite autour de son sens étymologique, de ses archétypes, et de son histoire. À travers elle sont notamment théorisés : les conditions de la résilience et leurs aspects qualitatifs ; le rapport à la forme architecturale, au temps et au lieu d’un urbain conçu selon ses critères ; sa symbolique et son décalage vis-à-vis du modèle dominant ; sa dimension politique, dialogique, expérimentale et incrémentale ; les repères et seuils orientant des choix architecturaux et urbains. / The concept of resilience has been adopted by the language and practices of growing global urbanisation, the dominant model of which is planning. However, resilience theory is also questioned, notably for the difficulty it manifests in ensuring predictable results, or for the usage that is made of it by the most neoliberal approaches to planning. This thesis shows that concept of resilience can also be a starting point for questioning planning by introducing other ways of understanding, theorising and designing urban environments. It addresses how urban resilience theory can shed light on specific conceptual frameworks, whose criteria may orient design choices. The research originates in a corpus that has been developed in the field of ecology, opening the way to an urban resilience theory, and explores the singularities of this transition. To overcome the dominant model’s tendency to blur landmarks, and free this process of theorisation from the ambiguity of its frameworks, this thesis adopts the method of analysis through metaphor. It thus proposes the concept of "urban piracy", as an art of designing resilience in urban environments. The metaphor of piracy is constructed along its etymological sense, its archetypes and its history. It gives way to a theorisation that includes the qualitative aspects of the conditions of resilience; the relationship to form, time and place, of a city designed according to its criteria; the symbolism of its theory and its discrepancies vis-à-vis the dominant model; its political, dialogical, experimental and incremental dimension; and finally, the landmarks and the thresholds that orient choices in architectural and urban design.

Pupils from a low SES differ in their development within the same school context. It is argued that the mechanisms through which education and the school environment as a whole can contribute to the successful development of children from a low SES should be identified and mapped. Therefore a focus on the mechanisms that lead to children with a low SES succeeding, in addition to discussing the reasons for these children not succeeding is proposed. The present research is drawn upon bio-ecological and symbolic interactionist theories of human development in an effort to understand resilience as involving person-context transactions. Specifically, the resilience of adolescents in the school context is studied as a joint function of personal characteristics and social contextual affordances that either promote or thwart the development of person-level, resilient-enhancing characteristics. The study employed inductive as well as deductive methods for knowledge development. Firstly, the concept of “resilience” was defined and operationalized in a Resilience Questionnaire (VVL). This questionnaire was validated on 399 middle-adolescents from five Educational Opportunity Schools in the Netherlands. Secondly, the inductive “Grounded Theory” method was followed with 21 middle-adolescents from three of the five Educational Opportunity Schools. In answer to the main question “How does the school environment contribute to the resilience of middle-adolescent students?”, the school environment can contribute to resilience through facilitating safety and good education. Resilient and Not-Resilient middle-adolescents differ in their dependence on the school environment for their access to these resilience-enhancing circumstances and factors. In relation to the first sub question, “What are resilient middle-adolescents’ perceptions of the contribution of the school environment to their resilience?”, the school environment contributes to the resilience of resilient middle-adolescents by challenging them (e.g with high expectations) and by offering opportunities to create constructive relationships with adults and fellow students in the school environment (e.g through informal conversations and through keeping order in the classroom). In answer to the second and third sub questions, “What are the perceptions of not-resilient middle-adolescents of the contribution of the school environment to their state of resilience?” and “How can the comparison between these two perceptions be explained?”, Not-Resilient middle-adolescents identify and utilise the services and potentially protective factors in the school enviroment less of their own accord than Resilient middle-adolescents do. The school environment can contribute to the resilience of Not-Resilient middle-adolescents by facilitating an overview, insight and positive future expectations in a very direct, controlling manner: An overview over risks for one’s own development and the presence of potential resources to assist one’s own development; insight into his or her own abilities to deal with possible risks; and positive future expectations on the improvement of a situation after a problem or risk has occurred. In summary, the daily situations in the school environment offer enough tools to contribute to the resilience of resilient and not-resilient middle-adolescents. These should, however, be recognised by both the middle-adolescent and the adults in the school environment as opportunities for development, which should subsequently be grasped in order to learn to deal with these challenges constructively. / Thesis (PhD (Learning Supoort, Guidance and Counselling))--University of Pretoria, 2007. / Educational Psychology / PhD / unrestricted

Following the terrorist attacks on the United States on September 11, 2001, many turned to the field of psychology for greater understanding of the impact of such events and guidance in supporting our citizens. This study sought to gain greater understanding of the differential impact of the September 11th attack on individuals by investigating the influence of age, psychological hardiness, and repression versus sensitization as forms of coping behavior on psychological health. Both an initial cross-sectional sample (172 young adults & 231older adults) and a short-term longitudinal follow-up (39 young adults & 58 older adults) were included in the study. Older age, psychological hardiness and the use of a repressing coping style were found to each individually relate to greater resilience/less dysfunction at both time one and two. For young adults, high hardy repressors faired best, followed by high hardy sensitizers. Low hardy young adults demonstrated similar levels of dysfunction regardless of coping style (repressions/sensitization). For older adults, coping style impacted both high and low hardy individuals equally, with high hardy repressors demonstrating greater functioning. This study attempted to gain greater insight into explanations for these and previous findings of greater resilience among older adults. In explaining the greater resilience of older adults, it seems that coping style is highly important, while hardiness and the impact of history-graded events does not explain the resilience of older adults.

Thesis advisor: Raquel Muniz / There is an abundance of research that both supports teachers’ developing the social and emotional competencies (SEC) of students and acknowledges that doing so positively impacts students’ academic and life success, as well as improving general well-being. As of 2020, Massachusetts required teachers to provide social emotional learning (SEL) opportunities for students, but district and school leaders have done little to develop teachers' own SEC.  Yet, the literature shows that teachers’ SEC matter, both to the successful implementation of SEL programs in classrooms and to teachers’ own ability to manage their emotions and handle stress. Teaching is stressful and high emotional stress can lower resilience and impact job performance. This qualitative case study examined the practices of school-based leaders in one Massachusetts public school district to determine which leadership practices developed and supported the resilience and well-being of school-based staff and how those practices promoted SEL opportunities for staff. Data was gathered from leaders and school-based staff through semi-structured interviews, questionnaires, and document review. Findings revealed that leaders developed and supported staff resilience and well-being when they provided opportunities for collaboration, recognized and provided feedback to staff, included staff in decisions related to their work, and supported work-life balance and self-care. Engaging in these leadership practices allowed leaders to promote SEL opportunities for staff and often modeled SEC for staff. / Thesis (EdD) — Boston College, 2020. / Submitted to: Boston College.

The acquirement of a disability (e.g., spinal cord injury, traumatic brain injury, amputation, multi trauma) is a risk factor for psychological disturbance (e.g., depression). Research has established that social support and secure attachment are protective factors against psychological disturbance. Attachment patterns have also been associated with differences in perceived social support. Secure attachment and higher perceived social support have been implicated in greater levels of resilience but need to be validated with a population of individuals who have acquired a disability. The Experiences in Close Relationships, Social Provisions Scale, Connor-Davidson Resilience Scale, Personal Health Questionnaire - 9 Depression Scale, and a Demographic were administered to 102 adult inpatients at a rehabilitation hospital undergoing an individualized rehabilitation program. Two MANOVAs were conducted to examine the direct associations of attachment classifications with the major dependent variables, as well as the various social support subscales. Path analysis tested two mediational models suggested by literature. Model 1 assessed the mediating role of attachment anxiety and attachment avoidance on the effect of social support on depression and resilience. Model 2 assessed the mediating role of social support on the effect of attachment anxiety or attachment avoidance on depression and resilience. Partial support was obtained for both models based on fit indices. A small but significant difference in the fit of the models was found, favoring Model 1. Clinical and research implications for this population and the limitations of the study are discussed.

M. Tech. (Department of Human Resource Management, Faculty of Management Sciences), Vaal University of Technology. / Law enforcement departments require staff members that are psychologically stable when facing stressful, unpleasant and undesirable situations during work activities. The literature indicates that law enforcers are exposed to dangerous and unpredictable situations; hence, emotional intelligence, resilience and happiness are important to them. Although the relationship between emotional intelligence (EI), resilience and happiness are considered essential, previous research based on these constructs within the law enforcement departments is limited. Therefore, the aim of this study was to determine the relationship between EI, resilience and happiness among police officers in the Sedibeng West District in the Gauteng province, South Africa. The study followed a quantitative research approach and a probability sampling method to achieve its empirical objectives. A self-administered questionnaire was distributed to 400 police officers within the Sedibeng West District. 330 responses were received, which resulted in a response rate of 82.5 percent for the main study. Descriptive statistics were used to analyse the data to determine the levels of EI, resilience and happiness among police officers and the results were positive. Correlation analysis was undertaken to investigate the existence of an association between the constructs. The results indicated a weak positive association between the self-emotion appraisal (SEA) dimension of EI and resilience recovery, and a positive association between the SEA dimension and resilience control. A weak positive association between the use of emotion (UOE) dimension of EI and resilience recovery was revealed and a positive association between UOE and resilience control as well. A significant weak positive association was indicated for the EI dimension other’s emotion appraisal (OEA) and resilience recovery, and a positive association between OEA and resilience control was also revealed. A significant weak positive association between the regulation of emotion (ROE) dimension of EI and resilience recovery, and a moderate positive association between ROE and resilience control was reported. Lastly, a moderate positive association between resilience recovery and happiness was reported and a positive, however, weak association between resilience control and happiness was reported. Regression analysis was undertaken to determine the predictive relationships between the constructs. The results showed no predictive relationship between SEA and resilience recovery and resilience control; between OEA and resilience recovery and resilience control; and between UOE and resilience recovery and resilience control. A significant predictive relationship between ROE and resilience recovery and resilience control was revealed. Lastly, a predictive relationship existed between both resilience dimensions (resilience recovery and resilience control) and happiness. The study recommends that law enforcement departments should develop police officers’ EI, resilience and happiness by promoting subjective well-being (SWB) programs. Programs focusing on EI may be implemented to enhance knowledge on how to regulate and manage emotions. Mental health clinics and debriefing sessions should be held to provide police officers with moral support. Finally, an action-oriented approach to assist police officers with their coping strategies and behavioural treatment is also recommended. The study also recommends that the involvement of Human Resources Development (HRD) within police departments should serve to support the wellness and development of police officers.

Thesis (Ph.D. (Psychology)) -- University of Limpopo, 2022 / Climate change poses a major threat to both the well-being of people and the environment. Subsistence farmers are particularly affected because they rely on local supply systems that are sensitive to climate variation. The aim of the study was to explore psychological resilience factors associated with climate change adaptation by subsistence farmers in a rural farming community in Maruleng Municipality in Limpopo Province (South Africa). The objectives of the study were to: investigate subsistence farmers' notions of climate change and adaptation; determine the psychological resilience factors influencing the farmers’ adaptation the climate change; determine strategies that the farmers use to cope with climate change; and, based on the farmers’ notions of climate change and adaptation, and the associated resilience factors, develop a psychological explanatory model on climate change adaptation by subsistence farmers. Data were collected through direct interactions with participants using a grounded theory research design. An open-ended interview guide was used to collect data with a sample of 15 participants selected through theoretical sampling within the Maruleng Municipality. The research findings indicate that farmers have limited conceptual knowledge relating to climate change and its causes. The results further indicated that participants have become resilient to climate change through mitigation strategies including mulching, adaptive irrigation techniques and being innovative. From a psychological perspective, the subsistence farmers’ resilience factors that emerged included passion for farming, hope, enthusiasm, courage, acceptance or tolerance, livelihood and a coherent belief system. Based on the findings of the study, a psychological explanatory model in climate change adaptation by subsistence farmers was developed. The explanatory model suggests that resilience factors are influenced by notions and adaptations of climate change. The study is concluded by, among others, recommending that counseling services be made available to farmers to help them deal with the stress associated with the negative impact of climate change.
