Bayesean Analysis as a Predictor of outcome rate.
Power calculations in clinical trials depend on an estimation of a change in effect size, and this depends on an estimation of the rate of the (measured) event in the population. It may be that using a Baysian approach ... -
GIS as a mine rehabilitation tool: examples from Wangaloa Coal Mine
At the Wangaloa Coal Mine, South-East Otago, ArcGIS is being used to manage, integrate, analyse and visualise the diverse range of datasets being generated from an interdisciplinary research team. GIS will assist with ... -
Geographic information systems at AgResearch
AgResearch is New Zealand’s largest Crown Research Institute and undertakes research in the areas of pastoral agriculture and environment, applied biotechnologies, and food and textiles. While there is a great deal of scope ... -
Calculating the 2D motion of lumbar vertebrae using splines
We present a new method for calculating the transformation parameters for a rigid body undergoing planar motion parallel to the image plane. The method utilises splines to represent the outline of the rigid shape rather ... -
Phylogeography of carnivorous snails from Northland
Landsnails of the subfamily Paryphantinae are active carnivores on earthworms and other snails. Most species are endemic to Northland, New Zealand, are several are of conservation concern, being threatened by habitat ... -
Location, location, location: quantifying high density patterns of Hector’s dolphin in relation to oceanographic features
Hector’s dolphin (Cephalorhynchus hectori) is the only endemic dolphin species to New Zealand waters. From population estimates, it has been established that this species is one of the rarest of the world’s cetaceans and ... -
Biodiversity and genes on landscapes
Modelling the relationship between the genetic distribution of a biological system on a landscape, and the diversity of this system, are fundamental concepts that can be studied using simulation models. This work examines ... -
The conservation status of New Zealand’s indigenous grasslands
The conservation status of New Zealand's indigenous grasslands has been assessed, as of September 2002, against an 1840 baseline, i.e., immediately before European settlement when New Zealand grasslands were essentially ... -
The evolutionary consequences of phenotypic plasticity: adding spatial dimension
I describe a model for the evolutionary consequences of plasticity in an environmentally heterogeneous metapopulation in which specialists for each of two alternative environments and one plastic type are initially present. ... -
Spatial data mining: where to from here?
The field of spatial data mining (Chawla, Shekhar,Wu & Ozesmi 2001), has been influenced by many other disciplines such as neural networks (Rumelhart, Hinton & Williams 1986), machine learning (Mitchell 1997), fuzzy systems ... -
Quality of data for geo-spatial studies of alcohol-related harm
There is growing research interest in the relationship between the geographic density of liquor outlets and the incidence of various harms (e.g., assault), however, to date, detail is lacking on the quality of data used ... -
The ARGOS project and the role of GIS
The paper introduces ARGOS, the Agriculture Research Group on Sustainability and discusses the potential role GIS can play within. The ARGOS programme examines the environmental, economic and social sustainability of ... -
Hector’s Dolphin database for a South Island bay: a new tool for the research toolbox?
Hector’s dolphins are an endemic species found along coasts in both the North and South Islands in New Zealand. They are primarily observed along the coast within 5 nautical miles (nm) of the shore. Surveys conducted during ... -
Power and persuasion: GIS as a tool to combat inequality; injustice and environmental destruction in the Bluff oyster fishery
Science has provided marvellous descriptions of the Foveaux Strait and of the creatures and ecosystems that it contains, but this has not been enough to prevent a tragedy in Bluff. The tragedy is the loss of the Bluff ... -
An integrated GIS for Fiordland’s marine habitats
As part of a multi-year research project looking into the regional biodiversity and management of Fiordland’s marine habitats, a GIS has been developed to manage and enhance the combined weight of many years of biological ... -
Spatial location of genes within cells in gene interaction networks
Text mining techniques have become a popular method for discovering relationships between genes based on searching the biomedical literature. The co-occurrence of gene names within individual documents is used to produce ... -
Two new tools for aggregation and geoprocessing of raw spatial data
The journey to successful data analysis is vulnerable to loss of accuracy at several key steps in its progression. Thus the ease of understanding the results and strength of insight into a work’s implications depends on ... -
Does space always matter in the origin of biological species
For the last 40 years one of the most contentious issues in evolutionary biology has been determining the role that spatial separation of populations plays in the generation of new species. Most early formulations of this ... -
Revealing the local geospatial knowledge base of oyster fishing at Bluff, New Zealand
This presentation discusses and demonstrates ways in which modern technology, specifically Web-based GIS (augmented by low-tech data gathering strategies), and a web page based on local meetings of fishermen and other ... -
Density-dependent breeding site selection in translocated populations South Island Robin and South Island Saddlebacks
Reintroduction of threatened species to predator-free offshore islands has long been advocated in New Zealand as a prime management tool for conservation. They also provide a good experimental framework to investigate ...
