title: Analysis of ICP variants for the registration of partially overlapping time-of-flight range images

authors: Larkins, Robert L.

subjects: ICP

abstract: The iterative closest point (ICP) algorithm is one of the most commonly used methods for registering partially overlapping range images. Nevertheless, this algorithm was not originally designed for this task, and many variants have been proposed in an effort to improve its prociency. The relatively new full-field amplitude-modulated time-of-flight range imaging cameras present further complications to registration in the form of measurement errors due to mixed and scattered light. This paper investigates the effectiveness of the most common ICP variants applied to range image data acquired from full-field range imaging cameras. The original ICP algorithm combined with boundary rejection performed the same as or better than the majority of variants tested. In fact, many of these variants proved to decrease the registration alignment.

title: Culture and Cognitive Theory: Toward a Reformulation

authors: Thakker, Jo

subjects: culture

abstract: In a provocative and important recent article Anthony Marsella (1998) makes an eloquent plea for the forging of a new metadiscipline of psychology that he labels global-community psychology. Marsella argues that we need a radical rethinking of the fundamental premises of psychology, rooted as they are in Western cultural traditions. Features of an emergent global-community psychology include an emphasis on multicultural and multidisciplinary approaches to human behavior that draw attention to the importance of context and meaning in human lives. Marsella's call for a global-community psychology reflects, in part, a growing body of literature that demonstrates the importance of cultural factors in a diver-sity of psychological domains such as cognition, emotion, social behavior, and psychopathology.

title: A Mana Wahine inquiry into indigenous governance

authors: Toi, Sharon Marjorie

subjects: Mana Wahine

abstract: This thesis investigates the question “How can indigenous women reinvigorate their role in tribal governance structures when many such structures continue to reinforce gendered colonial constructs within which women are marginalised?”  It is noted that contemporary tribal governance structures are often considered a site within which indigenous peoples can express cultural identity, however, when indigenous women are clearly under-represented in positions of power within those structures, this thesis questions why this situation continues. 
First, the thesis seeks to address the broad historical context within which indigenous women were subjected to colonial constructs of legislation, paternalistic government policies and the mechanisms of a euro-western court system policy. It is against this backdrop that comparisons are drawn that take into account the historical relationships between Māori, First Nations, Aboriginal, and Native American women and their respective colonising governments which bear alarming similarities in terms of the subjugation of these populations of women through colonisation. The significance of this historical-comparative lens is to illustrate how the status of women became seriously eroded within indigenous societies from traditional through to modern times. Consequently, this thesis goes on to explore the contemporary socio-political status of indigenous women as a result of their colonised history. 
From this broad historical context, the thesis narrows its view to examine commonalities and differences in relation to Māori and Native American women's experiences of tribal governance as tribal leaders and women of cultural significance and influence. The thesis changes tack to reflect the specific research intent of my Fulbright scholar experience to the University of Arizona, Tucson Arizona. Narrowing the focus of the research allowed me to analyse in more detail, beneficial comparisons of what was working for women tribal leaders under the auspices of the largely successful Native Nations Institute, Indigenous Governance Programme, in comparison to Māori women in tribal governance in Aotearoa, New Zealand. Importantly, this research synergises indigenous women’s shared knowledge in the reinvigoration of traditional tribal governance structures. The objective being to establish a body of knowledge that gives strength to a collective indigenous women's experience of governance from which normative propositions of indigenous governance based on western concepts can be examined, challenged and potentially transformed.  
It is noted that indigenous women have been included as essential decision-makers and leaders in traditional tribal governance systems; however, contemporary indigenous governance models do little to reflect this. The impact is that for indigenous women, tribal institutions and structures can themselves embed and reflect western colonial and patriarchal ideologies. Through our colonial experiences, indigenous peoples have inherited an oppressive gender legacy entrenched in policy and legislation that is socially constructed and instructed. To survive, indigenous women have to engage, challenge, resist and mitigate gendered spaces. This research highlights the extent to which indigenous women’s ways of leading or governing continue to be circumscribed in the on-going process of colonisation. Colonialism was a gendered process, and consequently, this thesis draws upon indigenous Feminist, Kaupapa Maori and Mana Wahine (Māori women’s) theoretical frameworks to analyse the complex ways that intersecting discourses of colonialism, race, gender and power continue to marginalise indigenous women within tribal governance. Indigenous Feminist theory also provides a framework for contextualising how First Nations, Aboriginal and Native American/American Indian women speak to these issues.  Importantly, how indigenous women are engaging in decolonising methodologies that impact the colonised practices, ways and attitudes they have or are currently experiencing in tribal governance, are also revealed.
Lastly, this thesis contributes to legal scholarship by contextualising the specific challenges of tribal governance for indigenous women. It addresses this by situating women’s experiences and ways of ‘being and doing’ within the micro tribal governance context while taking account of the macro realities of tribal governance politically, socially and more importantly, culturally.
