title: Timestamp representations for virtual sequences

authors: Cleary, John G.

subjects: computer science

abstract: The problem of executing sequential programs optimistically using the Time Warp algorithm is considered. It is shown how to do this, by first mapping the sequential execution to a control tree and then assigning timestamps to each node in the tree. For such timestamps to be effective they must be finite, this implies that they must be periodically rescaled to allow old timestamps to be reused. A number of timestamp representations are described and compared on the basis of: their complexity; the frequency and cost of rescaling; and the cost of performing basic operations, including comparison and creation of new timestamps.

title: Imagining Pākehātanga: how to be where you are

authors: Boyens, Aaron

subjects: Pākehātanga

abstract: Imagining Pākehātanga: how to be where you are is a creative practice thesis in which I explore the question: in what ways can I imagine Pākehātanga through personal experiences and shared family practices? In framing the contemporary context of Aotearoa / New Zealand I draw on literature relating to Decolonising Theory and Pākehātanga, leading to the development of a research design based on autoethnographic performance. The research was carried out in three phases using the following methods: individual interviews with family members; a session involving a thematic research conversation with a group of my family members; and creative practice throughout the project. The last phase culminated in an evening of autoethnographic performance incorporating creative writing, poetry and song. The performance script and an audiovisual recording of the performance are integrated with the written thesis text. Throughout the thesis, my creative writing weaves with my academic writing, revealing three clear responses to the research question: naming, listening, and longing. These responses function interdependently, together showing the potential for an infinite motion of imagination in action and possibilities for Pākehā practising a relational way of being. This is my quest of how to be, how to be where I am.

title: Why do Maori Disconnect?  From their tikanga and legal associated rights and responsibilities within a contemporary world

authors: Jones, Mary Te Kuini

subjects: Ahi Kaa

abstract: This thesis examines some of the reasons why Māori disconnect from their legal and tikanga rights and responsibilities within the contemporary world of today.  The aim of this research project is to identify some of the associated rights and responsibilities of Māori - as land owners, shareholders, Whānau, hapū and tribal members.  Whilst it seeks to reveal some of the desires and visions of the interview participants, the objective is not to seek resolution.  The focus is to identify what deters or dissuades owners from returning and/or participating.  It also seeks to identify whether the assumption or label of disconnection is a reality or myth. 

‘Māori Diaspora’ particularly refers to the substantial increase in outward migration (also referred to as out migration) of Māori leaving New Zealand, and more significantly migrating to Australia, which was in direct response to the neo-liberal reforms of the late 1980’s (Smith L. , 2006).   With the New Zealand government refusing to acknowledge the negative impact their legislation and policy had on Māori, they continued to introduce new systems that were ultimately designed to push many to breaking point.  
Māori who could no longer bear the cumulative effects of such oppression emigrated in search of better economic opportunities and a higher standard of living for their families.  Meanwhile, back home in Aotearoa, the Māori Diaspora left behind a complex set of problems in its wake with diminishing hapū and tribal members driven from their homeland who are gradually becoming dis-connected and estranged from their whenua tipu.   

Whilst repatriation is an uncomfortable topic for many Māori who wish to retain their overseas residency, many continue to dismiss the compounding effects of their absence and the heavy burden carried by those who remain in Aotearoa to keep the home fires burning (or the ‘ahi kaa’).
