Promoting Older Adults' Engagement in Disaster Recovery Through Supportive Relationships, Partnerships, and Collaboration: Perspectives of social Work Practitioners and human Service Professionals

引用

International Journal of Disaster Risk Science 2024年第2期15卷 265-276页

作者： Julie L.Drolet Mahed Choudhury faculty of social Work University of CalgaryEdmontonAB T5J 4P6Canada

Shifting demographics—that is, the growing number of older adults in Canada and internationally—and intersecting climatic risks create a complex landscape of aging in place in disaster contexts. Some older adults are vulnerable due to their underlying health conditions and limited physical mobility. Yet they also exhibit resilience in a distinct manner, owing to their wealth of knowledge, wisdom, and ability to navigate adversities. This article elucidates potential avenues for promoting the involvement of older adults in disaster recovery efforts. Our intention is to recognize and foster older adult resilience and mitigate vulnerability by drawing upon insights from the study titled “In the Aftermath of the 2016 Alberta Wildfires: The Role of social Work Practitioners and human Service Professionals in Long-Term Disaster Recovery.” Employing a qualitative research approach, that study recruited 51 participants for semistructured interviews and focus groups. A thematic analysis of the collected data unveiled the pivotal roles played by social workers and human service practitioners in facilitating recovery from the 2016 wildfires in the research. Notably, three overarching themes emerged concerning the promotion of older adults' involvement in disaster recovery: fostering supportive relationships, building partnerships and enhancing collaboration, and addressing ongoing challenges. These findings offer valuable insights into how social work practitioners and human service professionals can effectively facilitate the engagement of older adults in disaster recovery initiatives. This article emphasizes the significance of actively promoting the participation of older adults in disaster mitigation efforts, thereby fostering greater resilience within communities.

Between Euthanasia and Dysthanasia: The Ethical Issue of Sedation in the Terminal Phase of Illness

引用

Journal of Biosciences and Medicines 2024年第2期12卷 39-49页

作者： Joseph Sawadogo faculty of human and social Sciences Department of Philosophy Faculty of Medicine University Saint Thomas d’Aquin (USTA) Ouagadougou Burkina Faso

Background: Deep sedation, euthanasia and therapeutic relentlessness lead us today to rethink the paradigm of life and the contingency of human existence. Between therapeutic relentlessness, the unreasonable care which uses heavy therapeutic means which are often disproportionate to the expected benefit, namely keeping alive a patient whose condition is considered medically hopeless;and euthanasia which would precipitate the process of death would be sedation in the terminal phase of the illness. Should doctors and families of comatose patients decide the “life” and “death” of their patients? For anti-euthanasia associations, doctors, relatives of terminally ill patients and the State itself, if they accept the principle of euthanasia, they are “murderers”, while for pro-euthanasists, the dignity of the human being would recommend that the days of patients in situations considered critical be shortened, to avoid unnecessary suffering and humiliation. Methods: A systematic review of the literature was carried out to identify relevant articles relating to euthanasia, dysthanasia and sedation in the terminal phase of illness. The search was conducted in French or English in three databases: PubMed, Google Scholar and Science Direct. Objectives: The objectives of this article are: 1) define the terminologies and concepts of palliative sedation, deep sedation, deep and continuous sedation until death, euthanasia and dysthanasia;2) present aspects of the meaning of life and the human person in African cultures;and 3) propose an ethical reflection on the value of life. Results: After precisely defining the concepts of euthanasia, dysthanasia and sedation, this research presented the African anthropological and ethical approach to the mysteries of life and death. Conclusion: With this in mind, the golden rule of medicine always remains as such “Primum non nocere”.

“If I Do not Go to Work, They Will Die!” Dual Roles of Older-Adult Personal Support Workers' Contributions During the COVID-19 Pandemic

引用

International Journal of Disaster Risk Science 2024年第2期15卷 226-238页

作者： Haorui Wu Mandy Yung School of social Work Faculty of HealthDalhousie UniversityHalifaxNS B3H 4R2Canada

When COVID-19 devastated older-adult organizations(long-term care homes and retirement homes), most public attention was directed toward the older-adult residents rather than their service providers. This was especially true in the case of personal support workers, some of whom are over the age of 55, putting them in two separate categories in the COVID-19 settings:(1) a vulnerable and marginalized group who are disproportionately impacted by COVID-19;and(2) essential healthcare workers. Since the current disaster-driven research, practice, and policy have primarily focused on generalized assumptions that older-adults are a vulnerable, passive, and dependent group rather than recognizing their diversity, expertise, assets, and experiences, this study aimed to identify their contributions from the perspective of older-adult personal support worker(OAPSW). This qualitative study conducted in-depth interviews, inviting 15 OAPSWs from the Greater Toronto Area, Canada. This study uncovered the OAPSWs' contribution at three levels: individual(enhancing physical health, mental health, and overall well-being), work(improving working environment and service and supporting co-workers), and family(protecting their nuclear and extended families). The outcomes inform the older-adult research, practice, policy, public discourse, and education by enhancing the appreciation of older-adults' diverse strengths and promoting their engagement and contributions in disaster settings.
