title: Observations of alongshore variability of swash motions on an intermediate beach

authors: Guedes, Rafael Marcondes Carvalho

subjects: Alongshore variability

abstract: Alongshore variability in swash motions - shoreline oscillations about the mean water level on the beach face - were investigated using video images and a high-resolution morphology survey on an intermediate beach. Under mild, swell-dominated offshore wave conditions, alongshore variation of up to 78$ in significant runup height . Rs (defined as 4 times the standard deviation of the swash time series) was observed. This variation was predominantly driven by energy at the incident (>0.05. Hz) frequencies (where most of the swash energy was observed), and, consistent with previous observations, was mainly controlled by changes in the slope of the beach face (measured at the mean swash location). However, alongshore patterning in wave breaking over the sandbar caused variation in the degree of wave dissipation along the beach and also resulted in alongshore changes to swash motions. Although alongshore changes in beach slope and wave breaking patterning over the bar were observed to be typically correlated, both were needed in a regression model to provide the best explaination of alongshore changes in . Rs. At infragravity frequencies (<0.05. Hz), alongshore variability was not well associated either with changes in beach slope or wave breaking patterning. Low-mode edge waves were observed in the swash measurements and their contribution to the total energy spectrum was greatest near the location where a shoal was observed, suggesting this shoal may play a role in forcing. The edge waves may have contributed to the swash variability observed at infragravity frequencies. However, in these reflective conditions, the infragravity band plays a secondary role in controlling alongshore variations to swash motions.

title: Maximising potential: The psychological effects of the youth development programme Project K

authors: Furness, Kirsty

subjects: Adolescene

abstract: Project K is a positive youth development programme targeting 13-15 year old students with low self-efficacy. It involves three components: wilderness adventure, community challenge and individual mentoring. This longitudinal study aimed to investigate changes in self-efficacy, resilience, connectedness and wellbeing in students participating in Project K. Eighty students (59% male) were recruited from five secondary schools across the North Island of New Zealand for a quasi-experimental study. Participants displaying delinquent behaviour, self-harm, suicidal ideation, or an eating disorder were excluded. Over 14 months, six waves of measurement were completed by Project K participants (n = 49), while four waves of measurement were completed by a control group (n = 31). Analyses using multilevel models showed that completion of Project K had substantial positive effects on self-efficacy, resilience, and wellbeing, although the effect on connectedness was not significant. We conclude that Project K appears to be an effective positive youth development programme for adolescents with low self-efficacy.

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.
