Abstract: The purpose of this thesis has been to explore the discursive production of delirium in people over the age of 65 years. The philosophical approaches underpinning the study were derived from the field of critical gerontology, postmodernism and the utilisation of a Foucauldian understanding of discourse and power/knowledge. Data sources included published documents on delirium, interviews with people over the age of 65 years who had been delirious (as well as their clinical notes), family members, registered nurses and a doctor. Textual analysis revealed the presence of two contesting and contradictory discourses that impacted on being an older person who had delirium. These were identified as the discourse of delirium as a syndrome and a personal discourse of delirium. The discourse of delirium as a syndrome is underpinned by the biomedicalisation of the ageing process. This process utilises scientific methods as the foundation from which to understand, research and provide a health service to older people with delirium. Any personal perspectives on delirium are rendered unimportant and relegated to marginalised positions. Nursing through its vicarious relationship to medicine is interpellated into deploying the discourse of delirium as a syndrome and has largely ignored the personal dimensions associated with this phenomenon. Consequently, the older delirious 'body' is known and inscribed as unruly, problematic, physically unwell, cognitively impaired and at risk. Conversely, a personal discourse of delirium privileges the individual narratives of people who have been delirious and provides a different perspective of delirium. The deployment of a personal discourse of delirium offers another position that views this group of older people as bringing to the health care setting a rich tapestry of life experiences that are more than a cluster of signs and symptoms. It is these varied life experiences that need to be included as a legitimate source of knowledge about delirium. This thesis demonstrates how nursing needs to espouse a critical gerontological position when working with older people who have delirium. Critical gerontology provides nurses with the theoretical tools to challenge the status quo and uncover the multiple, varied, contradictory and complex representations of delirium in older people.

Abstract: The purpose of this research has been to trace the development of the nurse practitioner role in New Zealand. Using a discourse analytical approach informed by the work of Michel Foucault, the study foregrounds the discourses that have constructed the nurse practitioner role within the New Zealand social and political context. The author suggests that discourses of nursing and of medicine have established systems of disciplinary practices that produce nurses and physicians within defined role boundaries, not because of legislation, but because discourse has constructed certain rules. The nurse practitioner role transcends those boundaries and offers the possibility of a new and potentially more liberating identity for nurses and nursing. A plural approach of both textuality and discursivity was used to guide the analysis of texts chosen from published literature and from nine interviews conducted with individuals who have been influential in the unfolding of the nurse practitioner role. Both professionally and industrially and in academic and regulatory terms dating back to the Nurses Registration Act, 1901, the political discourses and disciplinary practices serving to position nurses in the health care sector and to represent nursing are examined. The play of these forces has created an interstice from which the nurse practitioner role in New Zealand could emerge. In combination with a new state regime of primary health care, the notion of an autonomous nursing profession in both practice and regulation has challenged medicine's traditional right to surveillance of nursing practice. Through a kind of regulated freedom, the availability of assessment, diagnostic and prescribing practices within a nursing discourse signals a radical shift in how nursing can be represented. The author concludes that the nurse practitioner polemic has revolutionised the nursing subject, and may in turn lead to a qualitatively different health service.
