title: Lake Rotoiti fieldwork and modelling to support considerations of Ohau Channel diversion from Lake Rotoiti

authors: Hamilton, David P.

abstract: A detailed assessment of the water quality effects of the Ohau Channel inflow to Lake Rotoiti was carried out using field and computer modelling analyses. The modelling assessment evaluates the effects on Lake Rotoiti of partial (50%) or complete (100%) diversion of the Ohau Channel. A comprehensive bathymetric survey of Lake Rotoiti and the eastern end of Lake Rotorua was also carried out to provide information for the application of a three-dimensional model run by NIWA, so that different diversion wall positions and designs might be tested prior to possible implementation. Field measurements based on temperature, conductivity and chlorophyll fluorescence carried out from February to May 2004 captured instances when the Ohau Channel entered Lake Rotoiti as a buoyant overflow. These data and historical records suggest that approximately 20% of the buoyant surface inflow enters the main basin of Lake Rotoiti, while the remainder is short-circuited through the Kaituna arm to the outflow.

title: Data mining as a tool for environmental scientists

authors: Spate, Jessica

subjects: data mining

abstract: Over recent years a huge library of data mining algorithms has been developed to tackle a variety of problems in fields such as medical imaging and network traffic analysis. Many of these techniques are far more flexible than more classical modelling approaches and could be usefully applied to data-rich environmental problems. Certain techniques such as Artificial Neural Networks, Clustering, Case-Based Reasoning and more recently Bayesian Decision Networks have found application in environmental modelling while other methods, for example classification and association rule extraction, have not yet been taken up on any wide scale. We propose that these and other data mining techniques could be usefully applied to difficult problems in the field. This paper introduces several data mining concepts and briefly discusses their application to environmental modelling, where data may be sparse, incomplete, or heterogenous.

title: Alternative anthropologies: Kete aronui from the Waikato

authors: McCormack, Fiona

abstract: As three anthropologists working at the University of Waikato in Hamilton, Aotearoa (New Zealand), we experience anthropology in our daily work in the context of our local histories, communities and politics. While many anthropologists are familiar with the critiques of anthropology that play out in the USA or Europe, the narratives and practices of anthropology from places such as New Zealand are less well known. We argue that these local, diverse experiences of anthropology can enlarge our international understandings and imaginations of what anthropology can be, as well as the challenges it may face.

Anthropologists working in New Zealand today face the same plethora of academic pressures as those found in their counterparts in North America, Britain and Europe; pressures instigated by decades of neoliberal reform, managerialism, and the impact of new entrepreneurial and corporate models of universities that shape everyday identities and social relationships (Shore 2010). Similarly, the critique of anthropology as a discipline rooted in colonial imperatives and practices, resounds in a society whose imperial history and settler colonial present continues to imprint on educational institutions, pedagogy and research. In New Zealand, no neat historical trajectory marks a path from extractive research, wherein Indigenous knowledge and ways of life are pottled for export to the empire’s core, to one based on mutuality, co-creation and the indigenisation of anthropological knowledge.
