L’évaluation de la vulnérabilité est indispensable pour permettre aux gestionnaires du risque d’inondation, publics ou privés, d’avoir une meilleure connaissance et de prendre des décisions concernant les moyens d’action à mettre en place. Notamment, la connaissance de l’efficacité des actions menées sur les territoires et de la capacité existante des territoires à faire face au risque peut influencer leurs choix et les politiques publiques de gestion. Toutefois, l’évaluation de l’efficacité d’une action à réduire les dommages liés aux inondations est complexe et difficile à mener. Par ailleurs, peu de travaux incluent la capacité d’actions dans l’évaluation de la vulnérabilité.L’objectif de cette thèse est de proposer une appréciation de la vulnérabilité tenant compte de la capacité d’action des territoires. Il s’agit d’une approche expérimentale de l’efficacité des actions, appliquée aux Programmes d’Action de Prévention des Inondations (PAPI) qui sont le dispositif phare de la politique de prévention du risque inondation en France. Elle repose sur une méthode à dire d’experts, associant les différents acteurs de la gestion du risque inondation en France / Assessing vulnerability to flooding is necessary in order to allow public or private stakeholders, involved in flood risk management, improving their knowledge and taking decisions with regards to flood risk management. In particular, knowing the effectiveness of implemented actions as well as the existing risk coping capacities on territories may impact their decisions and public policies. However, the assessment of an action’s impact on flood-related damages is characterized by high complexity. Few research works include the society’s capacity to take action in their models of vulnerability assessment.The objective of this research is to provide an assessment of vulnerability to flooding that takes in account this capacity of action. It relies on an experimental design that aims at assessing the effectiveness of actions through expert judgments. The panel of experts gathers varied actors involved in flood risk management. The method is implemented on Actions Programs for Flood Prevention, as they are a key component of the french flood risk management public policy

Compared to their white counterparts, college students of color often have to deal with extra stressors associated with racial/ethnic (R/E) discrimination. R/E discrimination has been shown to be associated with a variety of negative outcomes, including increased psychological distress. This study aimed to better understand the negative impacts of R/E discrimination on college students of color by examining an indirect effect model in which discrimination affected psychological distress through perceived social support. Further, the moderating roles of three novel variables: social dominance orientation, collective coping, and internalized racism were explored. We predicted that social dominance orientation and collective coping would weaken the positive association between R/E discrimination and psychological distress whereas internalized racism would strengthen this relation. Participants of this study included 239 students of color recruited from a university in the southern United States who completed a r
