This multi-method ethnographic study explores the everyday lives of people with dementia living in the community, cared for by a spouse or family member. It examines three case studies of individuals with early to moderate stage dementia. The latter were attending a weekly day-centre group and this thesis explores their interactions with each other, individual histories, tastes, habits and daily habits. The primary aim of the research was to explore the natural role of music in the lives of these subjects as individuals and as a group. In doing so, this undertaking shows how, in supportive environments, agency and capacity can flourish, leading to constituents of ‘re-covery’, to use mental health terminology. This highlights some of the important matters that are overlooked where perspectives emphasise dementia as a disease of the brain. By contrast, it illuminates the role of social and environmental factors and their contribution to well-being. After initial interviews with each individual and in some cases, members of their families, five months of participant observation followed, primarily located in a home-based day care service. The data set was formed from 178 hours of field observations, a number of audio-recordings made during the sessions, and detailed field notes. This study shows that a close-up focus on the minute details of how a person lives their life and ‘dwelling’ with them for an extended period will illuminate many of the processes that work toward maintaining the well-being of people with dementia and facilitate their revitalisation. Significantly, it was the integration of music within and alongside the everyday tapestries of activities and events which helped create a space for connection and pleasure. The thesis findings reveal how the participants in this research repeatedly demonstrated expertise and insight, albeit not always verbally expressed, but shown in and through forms of practice as regards what was required for their well-being and how to achieve it. This achievement, however, also relied upon thoughtful and creative collaboration with others (carers, family members, etc.), working alongside the participants for mutually beneficial ends. The thesis concludes that what is required for people with dementia and their well-being does not differ substantially from what is generally required by humankind, but there are certain skills and modes of co-operative assistance that are necessary to ensure and maintain the well-being of people with dementia.

This dissertation applies object-oriented rhetorics and posthuman philosophies to environmental policy deliberation in order to help bridge gaps between policy makers, scientists, and citizens. For environmental policy scholars the non-credentialed expertise of local, or indigenous stakeholders is valued as possessing technical, objective merit that can improve the development and implementation of environmental policies. However, the utilization of stakeholder expertise in environmental policy faces serious challenges in terms of finding common grounds for communication within complex techno-social systems, of overcoming deep cultural differences and perceptions, and grave ethical issues of access and power. This dissertation develops two case studies of marine fisheries policy debates using theories of material ontology to detail the process of how the expertise of ordinary citizens develops within the context of environmental policy and how that expertise might be better utilized. By employing object-oriented rhetorical theories to trace material agency through the Snook and Gamefish’s (SGF) stakeholder integration programs in Florida’s Spotted Seatrout and Common Snook fishery debates, this dissertation argues that a material ontology of expertise offers a means of assessing the quality of lay-publics’ non-credentialed expertise. This dissertation suggests that an enriched since of what material objects are capable of rhetorically helps us develop tangible, actionable tools for environmental policy studies. By understanding expertise in terms of the accretion of material experiences, policy makers and scholars might more easily evaluate and utilize the expertise of environmental policy stakeholders

During the 1980s, an acute and deadly epidemic appeared in the United States. AIDS, a disease that initially affected mainly gay men, required a rapid and effective treatment. Due to tough regulations form government agencies and the stigma surrounding the disease, it would take a long time for a treatment to be developed. To break the silence, demand action and push for changes to combat the AIDS epidemic, the activist group ACT UP (AIDS Coalition to Unleash Power) was formed. A network formed around their actions that created an environment capable of developing new treatment methods. Using interviews, articles, and reports, this analysis will draw on Actor-Network Theory (ANT) to examine how ACT UP mobilizes lay expertise and navigates conflicts within its network to influence research processes and AIDS treatment. This analysis highlights the mobilization of lay expertise and shows how the constructive management of conflicts within networks can play a crucial role in challenging established research structures, influencing decision-making processes, and ultimately shaping the response to public health crises like the AIDS epidemic.
