title: Rapid progradation of the Pliocene-Pleistocene continental margin, northern Taranaki Basin, New Zealand, and implications

authors: Hansen, Rochelle J.

subjects: Taranaki Basin

abstract: Progradation and aggradation of the modern continental margin in northern Taranaki Basin has resulted in the deposition of a thick and rapidly accumulated Pliocene-Pleistocene sedimentary succession. It includes the predominantly muddy Giant Foresets Formation, and the underlying sandy Mangaa Formation. Investigation of the internal attributes and depositional systems associated with the Giant Foresets Formation suggests that it would provide very little effective reservoir for hydrocarbon accumulations, although it does provide essential seal and overburden properties. While the sand-dominated Mangaa Formation could be a hydrocarbon reservoir, drilling so far has yet to reveal any significant hydrocarbon shows. Undoubtedly the most significant contribution that the Giant Foresets and Mangaa Formations have had on petroleum systems in northern Taranaki Basin is the cumulative effect that rapid and substantial accumulation has had on maturation and migration of hydrocarbons in the underlying formations.
Palinspastic restoration of a seismic reflection profile across the Northern Graben, together with isopach mapping of stratigraphic section for biostratigraphic stages, indicates that the thickest part of the Pliocene-Pleistocene succession is along the central axis of the Northern Graben. Deposition of this succession contributed substantially to subsidence within the graben, providing further accommodation for sediment accumulation. Isopach and structure contour maps also reveal the extent to which submarine volcanic massifs were exposed along the axis of the graben and the timing of movement on major faults.

title: Focus and diversity in information systems research: Meeting the dual demands of a healthy applied discipline

authors: Taylor, Hazel

subjects: IS discipline

abstract: Drawing on sociology of science foundations, we argue that, in order to survive and prosper, healthy applied disciplines must meet the dual demands of academic and practitioner audiences by demonstrating both focus and diversity in their research. First, we use this concomitant modality to explain why previous studies into the structure of the Information Systems discipline have reported contradictory results, with some finding a focused field while others conclude that the field is diverse. In support of our argument, we then present the results of a longitudinal, author co-citation analysis, looking across the full range of journals in which IS research is published. Our results suggest that the IS field has sustained a focus on research within three subfields over a 20-year period from 1986 to 2005: (1) a thematic miscellany of research on development, implementation, and use of systems in various application domains; (2) IS strategy and business outcomes; and (3) group work and decision support. At the same time, the field has demonstrated considerable diversity within and around these core subfields, with researchers responding flexibly to the rapidly changing field by investigating these areas with new paradigms and in new contexts, and by exploring new topics including inter-business and Internet applications, computer-supported collaborative work, virtual teams, and knowledge management. Finally, we demonstrate that, over the 20-year period from 1986 to 2005, the discipline has shifted from fragmented adhocracy to a polycentric state, which is particularly appropriate to an applied discipline such as IS that must address the dual demands of focus and diversity in a rapidly changing technological context.

title: Tihei Mauri Ora: A Māori response to health disparities

authors: Waitoa, Alieta Jei

subjects: Maori

abstract: Māori bear a disproportionate burden of health problems which, in concert with other factors (e.g. poor housing, low socio-economic status and low education attainment), contribute to and maintain low health status. It is noted that there have been multiple attempts to reduce health inequities – however, such attempts have been largely unsuccessful. Barriers to success include government reticence, restrictions on Māori participation in determining health directions/solutions, current contract paradigms and a reluctance to engage in meaningful partnerships with Māori. Those barriers occur within a cultural framework which defines (and therefore prioritises) the health of an individual over the needs of the collective.

The hypothesis of this research is that Māori health disparities are best addressed via the development and delivery of Māori health models by services which are oriented to kaupapa Māori principles. Utilising a case study approach, this thesis looks at the outcomes generated when a kaupapa Māori service applies key Māori principles to health service delivery. The case study, in tandem with focus group interviews identifies the key elements necessary to developing services which are responsive to the needs of Māori.

This study identified the importance of promoting change (and ultimately improve Māori health status) that encompasses the formation of a framework which considers collective benefit over individualism, encompasses Māori values, acknowledges and accepts Māoricentric clinical interventions. In addition, the thesis asserts that Māori health status will improve once Māori are active participants rather than recipients of health services.
