title: Invasive fish and nutrients – fact sheet

authors: Hicks, Brendan J.

abstract: Invasive fish such as koi (or common) carp (Cyprinus carpio) are large fish as adults (typically 1-3 kg) and can exist at high biomass (commonly 1000-2000 kg/ha). Because of their large size, high biomass, and suctorial feeding behaviour that disturbs the lake bed, koi carp have the potential to contribute a significant amount of plant nutrients (nitrogen (N) and phosphorus (P)) to lake waters. To estimate the potential of koi carp to inhibit lake restoration, we estimated the rates of excretion relative to other processes contributing nutrients to lakes.

title: Re-designing Greenstone for Seniors

authors: Bennett, Erin Kay

subjects: Greenstone

abstract: The golden generation have a wealth of experience and knowledge from throughout
their lifetimes that younger generations wish to retain. In our technology filled world
an obvious means of collecting this information is electronically. Digital library col-
lections are increasingly used by libraries and large institutions to record their large
amounts of information but they can also be used for personal collections.
Seniors are often willing and keen to impart their years of experience upon people
of the younger generation but time is not always on their side as they grow older.
Throughout a lifetime a person could collect large amounts of papers, diaries, pho-
tos and media but the time it takes to organise these documents can be long and
exhausting and the person's health is not always at its best in old age.
Greenstone is a suite of software for creating digital libraries, which are organised
collections of documents. Greenstone has the ability to distribute collections either
using a server or CD-ROM, and provides advanced searching and organization tools.
While Greenstone is a versatile and useful tool in creating digital collections, its in-
terface is not designed for senior users. Seniors are commonly perceived to have
more physical and mental disadvantages as they get older. These disadvantages can
dramatically affect how usable seniors find a piece of software.
The aim of this thesis is to investigate how usable the current Greenstone interface
is for use by seniors and to re-design the interface so that Greenstone may be more
easily used by senior users. This thesis focuses upon what types of documents and
descriptive data seniors would like to include in a collection about their life. This is
to ascertain exactly what parts of the interface must be improved when it comes to
metadata and classifiers. The results of this investigation also helped in the creation
of a customised metadata set for senior users use.

title: Waikirikiri Marae: Shared experiences of the wharemate

authors: Rua, Hare

subjects: Māori

abstract: In Te Urewera, wharemate (shelters in which the deceased receive their final farewells) have traditionally been temporary structures. In the 1980s, a new practice was introduced in the Ruātoki valley with the erection of permanent wharemate facilities. One was erected at Waikirikiri marae (tribal meeting grounds and associated buildings) in 1989. Knowledge and discussion regarding wharemate at Waikirikiri marae have changed over the years, and a whole generation has not been fortunate enough to experience tikanga (correct procedures, customary practices) that prevailed prior to the introduction of the permanent wharemate building that is there today. These changes are recorded in this paper through the shared stories of three kaumātua (elders) from Waikirikiri.

This paper is a summary of Hare Rua’s thesis study, the data for which was collected in 2009. This work forms part of the Tangi Research Programme, a collaboration between the School of Māori and Pacific Development and the Māori and Psychology Research Unit at The University of Waikato, Hamilton, New Zealand.
