title: The movement of sediment in a channel in relation to magnitude and frequency concepts- a New Zealand example

authors: Pain, C.F.

abstract: In areas where surface wash contributes most of the debris to a channel network, the effect of events of moderate magnitude and frequency appear to be more important than catastrophic events for land form development. In previous studies this idea has been emphasised, largely as a result of the fact that the contribution of bedload to sediment yield has rarely been considered.
Examination of these ideas under certain New Zealand conditions would seem to present a somewhat different picture. Where rapid mass movement is the main contributor of sediment to the channel, both the development of hill-slope form and the movement of sediment in channels must be related to the frequency of occurrence of mass movements. The evidence seems to suggest that most major mass movements are triggered during high-intensity, low-frequency storms.
The Orere River catchment in the Hunua greywacke block of South Auckland, New Zealand, is examined to test these ideas. Although historical data are limited, the character of the sediments in the lower catchment would suggest a succession of major periods of deposition. High-intensity storms of 1966 and 1967 resulted in the deposition of large amounts of material in the channels throughout the catchment, with a gradual removal of material mainly from the upper catchment since that time. From the limited evidence that is available, a simple model of sediment movement through the catchment is presented.

title: Greenstone: Open source digital library software with end-user collection building

authors: Witten, Ian H.

subjects: computer science

abstract: The Greenstone digital library software is an open-source system for the construction and presentation of information collections. Collections built with Greenstone offer effective full-text searching and metadata-based browsing facilities that are attractive and easy to use. Moreover, they are easily maintainable an can be augmented and rebuilt entirely automatically. The system is extensible: software “plugins” accommodate different document and metadata types.
Greenstone incorporates an interface that makes it easy for people to create their own library collections. Collections may be built and served locally from the user’s own web server, or (given appropriate permissions) remotely on a shared digital library host. End users can easily build new collections styled after existing ones from material on the Web or from their local files (or both), and collections can be updated and new ones brought on-line at any time.

title: Ki te kapu o takau ringa - In the Hollow of my Hand: Wānanga based Photographic Approaches to Place Representation

authors: Hill, Rodrigo

abstract: Ka matakitaki iho au ki te riu o Waikato
 Ano nei hei kapo kau ake maaku; 
Ki te kapu o taku ringa, 
“I look down on the valley of Waikato, 
As though to hold it  
In the hollow of my hand.
 The words above are from Māori King Tawhiao’s maioha (song poem), a representation of his love for his homelands of the Waikato and the region known today as the King Country. Now imagine a large-scale photograph: a close-up of cupped hands, holding an object carefully. The phrase above informs Professor Tom Roa and Dr. Rodrigo Hill’s current research project titled ‘Te Nehenehenui - The Ancient Enduring Beauty in the Great Forest of the King Country’. With this project still in its early stages the research team will present early and ongoing creative practice developments, discussions and ideas about photography practice, wānanga, and place representation. The project promotes the use of wānanga (forums and meetings of focus groups through which knowledge - mātauranga - is discussed and passed on) and other reflective practices, engaging with and led by mana whenua (guardians of the land) providing a thread which will guide the construction of the photographic images. The research fuses wānanga, that is Mātauranga Māori (Māori Knowledge), and photography practice in novel ways, aiming to move away and challenge core photographic conventions and Eurocentric modes of place representation. Roa and Hill understand wānanga as a fluid practice of engagement which can be with mana whenua or with the taiao - the environment - either by itself or with the mana whenua. This is the essence of Kaupapa Māori Research.
