title: Improving the alignment of dynamic sheet-formed mats by changing nozzle geometry and their reinforcement of polypropylene matrix composites

authors: Sunny, Tom

abstract: The main objective of this study was to improve the orientation of fibres within the mats produced using dynamic sheet forming (DSF). DSF is used to make fibre mats by forcing a fibre suspension through a nozzle onto a rotating drum. In this research, the effect of nozzle geometry on the orientation of hemp fibres within DSF mats was investigated. The orientation of fibres within the mats produced was assessed using ImageJ (OrientationJ) and X-ray diffraction. It was found that, as the contraction ratio of the nozzle increased, the orientation of fibres within the fibre mats increased. It was also found that the composite tensile strength increased with increased fibre orientation.

title: (Re)presenting the Past: Historiographical and Theoretical Implications of the Historical Docudrama

authors: McKeown, Luke Daniel

subjects: history

abstract: This thesis contributes to the growing body of scholarship surrounding historical and filmic representations of the past. Moreover, it seeks to further the understanding and practical use of this sub-field in history by examining two films: Amistad (1997); and, The Wind That Shakes the Barley (2006). Building on the insistence of scholars such as Robert Rosenstone and Hayden White, this thesis seeks to evaluate historical films on their own terms as representations of the past that must be judged according to their own conventions. Cinema's attraction to historical subjects is not a recent phenomenon. However, the past two decades, have seen a marked increase in the academic critique of 'historical films' - most notably Hollywood features and television documentaries. Moreover, the appetite of the general public for filmic treatment of historical topics continues unabated. While it is agreed that historical film cannot be judged according to the criteria used in accessing traditional modes of historical representation, there is little agreement about what criteria, precisely, should be used in evaluating historical films' historical attributes and implications. This thesis commences with a general theoretical and methodological survey of the literature in this relatively new sub-field. It then analyses the film Amistad and its reception and criticism amongst historical professionals. This analysis, coupled with the findings of the first chapter, forms the basis for an original and independent review of The Wind That Shakes the Barley, a film that has not yet been widely critiqued by historians. The thesis suggests how historical films may be fruitfully evaluated in ways that are sympathetic both to the peculiar exigencies of the medium and the traditional concerns of historical scholarship.

title: Key informant views on biobanking and genomic research with Māori

authors: Hudson, Maui

abstract: The aim of the Te Mata Ira project was to explore Māori views on biobanking and genomic research, and to identify ways to address Māori concerns over the collection and use of human tissue. Key informant interviews and workshops were conducted with Māori to identify Māori views in relation to biobanking and genomic research; and, informed by these views, interviews and workshops were conducted with Māori and non-Māori key informants (Indigenous Advisory Panel (IAP) members and science communities) to explore key issues in relation to Māori participation in biobanking and genomic research. Māori key informants identified the following as key deliberations: (1) the tension for Māori between previous well-publicised negative experiences with genomic research and the potential value for whanau and communities as technologies develop, (2) protection of Māori rights and interest, (3) focus on Māori health priorities, (4) control of samples and data, (5) expectations of consultation and consent and (6) a desire for greater feedback and communication. Māori and non-Māori key informants highlighted the need to enhance levels of Māori participation in the governance of genomic research and biobanking initiatives, and acknowledged that only by increasing the level of transparency and accountability in relation to these activities will Māori communities feel that their whakapapa, rights and interests are being appropriately protected.
