To deal with and prepare for extraordinary events, the Czech Republic has the Integrated Rescue System, which is not an individual organization as such, but rather a system of co-ordinated activities of basic bodies, namely the Fire-Brigade of the Czech Republic and fire prevention units included in the area coverage, the Police of the Czech Republic and the Medical Rescue Service of the Czech Republic. It is the coordination of the Integrated Rescue System{\crq}s basic bodies what is absolutely essential for the effectiveness of the intervention in the place of an extraordinary event. To make the process of rescue and liquidation work really effective, type activities for the basic bodies during a collective intervention have been put together for selected extraordinary events. These activities focus mainly on the co-ordination of the bodies in the place of the extraordinary event as well as the co-ordination of the related bodies by their operations centres. This thesis aimed to analyze the work of the Czech Police as a body of the Integrated Rescue System in the area of extraordinary events as well as to point out possible insufficiencies and propose some ways of improvement. The findings gained can be used in the professional training of individuals, particularly from the ranks of the Czech Police, which handle the question of dealing with extraordinary events. The thesis includes a list of these type activities approved by the Integrated Rescue System{\crq}s bodies with reference to the effective legal documents and the analysis of responsibilities performed by the Police of the Czech Republic within the individual type activities. The conclusion indicates disparities between the theory and the practice, which arose during the elaboration of the thesis, particularly insufficient knowledge of the type activities on behalf of the policemen and deficient material facilities of the Czech Police as an Integrated Rescue System{\crq}s body, mainly protective aids for performing tasks related to potential contamination of the policemen by various chemical, biological and radioactive substances etc.

Au printemps 2020, une équipe interdisciplinaire (travail social, médecine et psychologie, notamment) et intersectorielle met sur pied la Clinique Mauve, un point de services intégrés pour personnes LGBTQI+ migrantes à Montréal (Canada). Parmi les services offerts, on trouve le programme de liaison, un projet innovateur d’intervention collective ayant pour but de réduire les impacts de la crise sociosanitaire sur cette population. Dans le cadre de ce mémoire, je cherche à 1) documenter l’expérience réalisée et 2) déterminer les leçons qu’on peut tirer de cet usage de méthodologies d’intervention collective dans un contexte de crise sociosanitaire. Pour y arriver, j’utilise principalement deux cadres théoriques : la typologisation de l’intervention collective de Bourque et al. (2007) et le modèle de résilience communautaire de Kirmayer et al. (2009). J’inscris ma démarche de recherche dans deux approches évaluatives : l’évaluation axée sur l’utilisation (Patton et Campbell-Patton, 2022) et l’évaluation descriptive en contexte de développement (Marceau, 2022 ; Rey et al., 2022). L’analyse des résultats met en lumière les forces et les limites de l’intervention collective, de l’intervention multilingue et culturellement adaptée et du soutien socio-économique et matériel en contexte de crise sociosanitaire de la COVID-19. Elle permet aussi de découvrir les nombreux défis qui ont ponctué la réalisation de cette expérience dans un contexte hors du commun. Une série de recommandations visant les responsables de la Clinique Mauve conclut ce mémoire. / In spring 2020, an interdisciplinary and intersectoral team (including social work, medicine, and psychology) established the Clinique Mauve, an integrated service point for LGBTQI+ migrants persons in Montreal, Canada. Among the services offered is the outreach program, an innovative collective intervention project aimed at mitigating the impacts of the socio-health crisis on this population. In the context of this thesis, I am seeking to 1) document the experience undertaken and 2) determine the lessons that can be drawn from the use of collective intervention methodologies in a socio-health crisis context. To achieve this, I primarily employ two theoretical frameworks: Bourque et al.'s typology of collective intervention (2007) and Kirmayer et al.'s community resilience model (2009). My research approach aligns with two evaluative approaches: utilization-focused evaluation (Patton and Campbell-Patton, 2022) and descriptive evaluation in a development context (Marceau, 2022; Rey et al., 2022). The analysis of the results highlights the strengths and limitations of collective intervention, multilingual and culturally adapted intervention, and socio-economic and material support in the context of the COVID-19 socio-health crisis. It also reveals the numerous challenges encountered during the implementation of this experience in an extraordinary context. A series of recommendations for the leaders of the Clinique Mauve concludes this thesis.
