title: The role of mass-movement in shore platform development along the Gisborne coastline, New Zealand

authors: McLean, R.F.

subjects: New Zealand

abstract: Tidal shore platforms form a conspicuous part of the coastal scenery north of Gisborne, New Zealand. Some of these platforms are being extended landward under present-day conditions. Present widening results primarily from cliff-retreat by mass-movement. The coincidence in distribution of areas of wave convergence, mass-movement and shore platforms suggests a genetic connection between these marine and subaerial process and response elements. Various types of mass-movement are involved in cliff-retreat, notably slumps, flows, debris slides and soil and rock falls. While the products of such mass-movement forms are removed by wave action, extensive boulder fields on some shore platforms indicate that removal is not always complete. Not all of the shore platforms on this coast are being widened at present. Widening has ceased where active mass-movement is not occurring.

title: Making better use of global discretization

authors: Frank, Eibe

subjects: computer science

abstract: Before applying learning algorithms to datasets, practitioners often globally discretize any numeric attributes. If the algorithm cannot handle numeric attributes directly, prior discretization is essential. Even if it can, prior discretization often accelerates induction, and may produce simpler and more accurate classifiers. 
As it is generally done, global discretization denies the learning algorithm any chance of taking advantage of the ordering information implicit in numeric attributes. However, a simple transformation of discretized data preserves this information in a form that learners can use. We show that, compared to using the discretized data directly, this transformation significantly increases the accuracy of decision trees built by C4.5, decision lists built by PART, and decision tables built using the wrapper method, on several bench-mark datasets. Moreover, it can significantly reduce the size of the resulting classifiers.
This simple technique makes global discretization an even more useful tool for data preprocessing

title: Local values and the promotion and restoration of wetlands and their ecosystem services in Aotearoa-New Zealand: a case study of Tauranga’s planning regime

authors: Peat, Helen Ann

subjects: Environmental planning

abstract: Aligning wetlands restoration planning mechanisms with public perceptions and values can help gain support for and assistance with restoration. Using Tauranga as a case study, this thesis is an exploratory study that applies the Millennium Ecosystem Assessment (MEA) framework to examine the extent to which New Zealand's planning regime incorporates local values in the promotion and restoration of wetlands and their ecosystem services.

This thesis used multiple qualitative research methods in a two-pronged process. A narrative literature review and systematic statutory analysis in phase one helped identify values associated with wetland ecosystem services and how New Zealand’s, and more specifically Tauranga’s, resource management system promotes and enables the restoration of wetlands and their ecosystem services. A case study approach with analysis of primary and secondary data in phase two helped identify what Tauranga local residents value as important wetland ecosystem services and the extent to which the local policy mechanisms reflect these values. 

Through thematic analysis of semi-structured interviews and summaries of submissions, this thesis identifies six dimensions that represent values towards wetland ecosystem services and their restoration in Tauranga. Other than one dimension that consists of a single value on education from the cultural services category of the MEA framework, the remaining five dimensions comprise services from within and between the framework categories. These dimensions are wetlands as nutrient- and mineral-rich areas that support biodiversity and provide habitat; that regulate water, act as natural flood plains and sequester carbon to help protect against climate change and natural hazards; that maintain Māori cultural practices; that remove nutrients and contaminants in water; and provide recreational and aesthetic experiences. Therefore, identified dimensions could form the basis of educational programmes and toolkits that promote wetlands restoration.

The systematic policy analysis and cross-comparison with the results of the thematic analysis found that Tauranga’s planning regime partially provides for each of the six dimensions. However, the nuances and complexities of the values, including the interconnected nature of wetlands values and services, are not captured. This means Tauranga’s planning regime does not fully incorporate local values in the promotion and restoration of wetlands and their ecosystem services. Bridging the gap between wetlands restoration provisions and wetland ecosystem service values is likely to be supported by enacting the current resource management reforms. Enacting the reforms would help reduce the number of policies and plans, implement regional spatial planning, and develop outcomes-based policy mechanisms that encompass ecological, social, cultural and spiritual values, including those associated with wetlands.
