title: Dynamic digital library construction and configuration

authors: Bainbridge, David

subjects: computer science

abstract: This paper describes a digital library architecture and implementation that is configurable, extensible and dynamic in the way it presents content and in the services it provides. The design manifests itself as a network of modules that communicate in terms of XML messages. All modules characterize the functionality they implement in response to a  describe yourself  message, and can transform messages using XSLT to support different levels of configurability. Traditional library values such as backwards compatibility and multiplatform operation are combined with the ability to add new collections and services adaptively. The paper describes the new design and shows how it can be used to build four different digital library systems. We conclude by showing how the design fits existing interoperability frameworks.

title: Emplacement processes of ignimbrites in the Ongatiti Valley, southeast Te Kuiti

authors: Brink, Megan Tracy

abstract: The Mangakino volcanic centre (MVC) is the oldest rhyolitic volcano of the Taupo Volcanic Zone (TVZ) located on the westernmost boundary. Ten eruptive deposits have been derived from the MVC and this study focuses on the 1.21 ± 0.04 Ma Ongatiti Ignimbrite and the 1.20 ± 0.04 Ma Unit D fall and overlying ignimbrite deposit. The Taupo volcanic centre (TVC), located at the southern boundary of the central TVZ is currently active and is considered to be the most active and productive rhyolitic centre on Earth. There have been multiple eruptions derived from the TVC over the past 350 – 320 ka, however the most recent Taupo eruption dated at 232 AD is the only deposit studied in this research. The study area is situated within the Ongatiti Valley, 15 km SE of Te Kuiti. It is 28 km west of the Mangakino caldera rim, and is located to the west of the upstanding Mesozoic basement block of the Rangitoto Range. 

A 1:25 000 geological map of the volcanic geology exposed within the Ongatiti Valley is produced. Detailed stratigraphc logs, petrographic descriptions and quantitative analysis on the mineralogy are given for all of the exposed eruptive deposits. The geochemical composition of the Ongatiti Ignimbrite and Unit D are determined through XRF, Electron microprobe and ICPMS analyses. 

Stratigraphic sections of the Ongatiti Ignimbrite in well exposed 25 m high outcrops in the Ongatiti Valley show variations in pumice, crystal, and lithic abundance, both vertically and laterally. Two units can be distinguished within the Ongatiti Ignimbrite overlying a poorly exposed lowermost fall deposit: a lower densely to partially welded, crystal-rich, pumice-poor flow sequence, and an upper densely to partially welded pumice and crystal-rich flow sequence. The boundary between the two units is wavy and gradational, and varies in altitude over relatively short distances. This undulating boundary is considered to result from interaction of pyroclastic density currents flowing both over and around the high-standing Rangitoto Range, and then covering a highly irregular pre-ignimbrite topography in the King Country. 

In the Ongatiti Valley, Unit D consists of several phreatoplinian fall deposits, a fine-grained ignimbrite and an overlying coarser-grained ignimbrite with a combined thickness of 3 m. A stratigraphic log is presented and the characteristic textures, structure, petrography and geochemistry is described. A six stage process is suggested for the change in the conditions/styles and intensities between the different phases of the eruption. 

A 15 m high valley-ponded section of the 232 AD Taupo Ignimbrite occurs in the Waipa River Valley, that contains fossilised tree trunks in position of growth. A possible origin involving variation in dynamic pressure and subsequent destructive power of pyroclastic density currents is developed.

title: An external evaluation of Phat Pak process and structure: Volume 1: Evaluation report

authors: Masters-Awatere, Bridgette

subjects: psychology

abstract: An evaluation was conducted by the 510 Evaluation Research Group 2007 after receiving a request from the Phat Pak Governance Group (PPGG). The evaluation focused on four areas identified in the Phat Pak service specification plan attached to it’s Ministry of Health contract (Youth participation, Communication Strategies, Decision making Processes and Skills Development). Our intention of evaluating the Phat Pak Programme has been to, through feedback from a range of participants, gauge the extent that the programme objectives (such as those highlighted in the contract are being met. More specifically, the function of the evaluation has been to help identify specific areas that are working well and those areas that need further development. It is our intention that the evaluation will provide both short and long-term direction with added insight towards increasing participation and enhancing health outcomes for youth and the wider community of the Waikato region.
