title: Developing a GIS-Based Decision Support Tool For Evaluating Potential Wind Farm Sites

authors: Xu, Xiao Mark

subjects: Wind farm site selection

abstract: In recent years, the popularity of wind energy has grown. It is starting to play a large role in generating renewable, clean energy around the world. In New Zealand, there is increasing recognition and awareness of global warming and the pollution caused by burning fossil fuels, as well as the increased difficulty of obtaining oil from foreign sources, and the fluctuating price of non-renewable energy products. This makes wind energy a very attractive alternative to keep New Zealand clean and green. 

There are many issues involved in wind farm development. These issues can be grouped into two categories - economic issues and environmental issues. Wind farm developers often use site selection process to minimise the impact of these issues. This thesis aims to develop GIS based models that provide effective decision support tool for evaluating, at a regional scale, potential wind farm locations. This thesis firstly identifies common issues involved in wind farm development. Then, by reviewing previous research on wind farm site selection, methods and models used by academic and corporate sector to solve issues are listed. Criteria for an effective decision support tool are also discussed. In this case, an effective decision support tool needs to be flexible, easy to implement and easy to use. More specifically, an effective decision support tool needs to provide users the ability to identify areas that are suitable for wind farm development based on different criteria.  Having established the structure and criteria for a wind farm analysis model, a GIS based tool was implemented using AML code using a Boolean logic model approach. This method uses binary maps for the final analysis. There are a total of 3645 output maps produced based on different combination of criteria. These maps can be used to conduct sensitivity analysis. This research concludes that an effective GIS analysis tool can be developed for provide effective decision support for evaluating wind farm sites.

title: Performance at the cost of well-being? Testing the multi-level effects of HR practices on organisational performance via employee experiences and well-being

authors: Sutton, Anna

abstract: Purpose
While the potential for HR practices (HRPs) to improve organisational performance is well-established, the mechanisms by which this occurs are complex. Individual HRPs may affect organisational performance either by mutual gains (improving both organisational performance and employee well-being) or by conflicting outcomes (organisational performance is improved at the expense of employee well-being). Models which combine HRPs may mask these differences and this study therefore tests pathways for four individual HRPs.
Design/methodology/approach 
HRPs (employee involvement, pay, performance management and training) were hypothesised to influence organisational performance directly and indirectly via employee experiences of work (communication, autonomy) and employee well-being. The study used a large secondary dataset, the UK Workplace Employee Relations Survey 2011, to test these relationships in a multi-level model.
Findings
Employee experiences of work strongly predicted well-being. In addition, three different pathways from HRP to organisational performance were identified. Pay showed indirect negative effects, involvement had direct positive effects and performance management had a mixture of both positive direct and negative indirect effects on performance.
Originality/value
Using a disaggregated analysis of HRP and demonstrating their differing effects, this study questions the feasibility of a universal model of HRP effects. By using multi-level modelling (MLM), the study develops understanding of employee perspectives and integrates these into organisational-level models, demonstrating that performance effects are partially mediated by both employee experiences of work and employee well-being. Finally, the study highlights the complexity of performance effects achieved via both employee benefits and an intensification of employee experiences.

title: Māori transitions into tertiary education

authors: Amundsen, Diana Leigh

subjects: Maori

abstract: This thesis critically examines Māori transitions into tertiary education. The research explored the lived transition experiences of 20 Māori tertiary education students in the Bay of Plenty region. Historical and contemporary factors in Aotearoa influencing effective Māori student transitions into tertiary education were investigated. Data were collected and analysed through repeated semistructured interviews and focus groups over the 2016-2018 period with 20 Māori students enrolled in a wānanga, a polytechnic and a university. Participants experienced their transition as a journey, continuously evolving their identities and agency in relation to the tertiary education environments and social structures they encountered.
The findings suggest that transitions to tertiary education for Māori students involve a reciprocal interplay of identity, agency and structure which support or constrain transition experiences. Effective transition experiences were underpinned by processes of continuity enabling identity growth. Support was central to how well participants perceived their transition—racism and lack of support were significant barriers; suitable support was a significant enabler.
An over-riding theme from this research related to the interplay of power relations and Māori identity. How effectively participants developed a sense of belonging (or alienation) and identity growth linked to the tertiary education environments they encountered during their transition. Within wānanga, participants felt their Māori cultural identity was highly valued; within polytechnics, there was a sense that Māori culture is included but more could be done; within universities, a need for more inclusive practices to support Māori learner requirements was identified.
Lastly, this research was conducted by a Pākehā researcher working across kaupapa Māori spaces within interpretive and critical paradigms. Unexpected moments of struggle, discomfort and vulnerability opened up new and deeper understanding of implications for Pākehā educators and researchers engaging across Māori research spaces. This thesis argues for Pākehā to use their privilege to foster more equitable social structures. Equitable social structures would be beneficial for Māori transitions into tertiary education environments.
