title: Document level interoperability for Collection Creators

authors: Bainbridge, David

subjects: computer science

abstract: Digital library interoperability for both documents and metadata is a critical and complex issue. Although many relevant standards have been developed, and continue to evolve, in practice things are not quite so easy as they seem. We have built a software environment called the Exchange Center that helps digital librarians manage the process of sourcing documents and metadata from various repositories, adding local content where necessary, and exporting the resulting collection into formats that are suitable for digital library repositories. This paper describes the software, which is built on Greenstone but does not require its use as the final digital library server.

title: The development of a national curriculum in technology for New Zealand

authors: Jones, Alister

abstract: New Zealand under went major curriculum reforms in the early 1990's. These reforms were determined by the New Zealand Curriculum Framework which provides an overarching framework for the development of curricula in New Zealand and which defines seven broad essential learning areas rather than subject areas. Technology is important and should be part of the education of all students. Six grounds for developing technology education were given, namely: economic, pedagogic, motivational, cultural, environmental, and personal. This paper reports on the development of a technology curriculum in schools. The philosophy of the curriculum will be discussed, particularly crucial aspects such as inclusiveness. The way in which the technology curriculum has attempted to meet the needs of a New Zealand technological society will be examined. The general aims of technology education in Technology in the New Zealand Curriculum are to develop: technological knowledge and understanding; an understanding and awareness of the interrelationship between technology and society; technological capability. The development of seven technological areas for all students will be highlighted. This paper will discuss in detail the development of the national technology education policy and the way in which the curriculum was developed. The last section of the paper will consider issues related to teacher development programmes and areas of future research.

title: Monitoring and hydrodynamic modelling of groundwater inflows into Lake Rotokakahi, New Zealand

authors: Noakes, Katie

subjects: Groundwater

abstract: Lake Rotokakahi is located 10 km south of Rotorua and is of immense cultural importance to the local iwi. The lake also has significant historical and recreational values, which prompted iwi to make the lake private in 1996. Lake Rotokakahi is one of several Rotorua/ Te Arawa lakes. Several of these lakes have become eutrophic and some have declining water quality. This study was prompted by declining water quality of Lake Rotokakahi and the need to identify potential sources of nutrients to the lake, particularly groundwater inflows.

The interaction between groundwater and surface water has a major influence on the trophic status of lakes, particularly those that are predominantly or solely groundwater fed systems. Lake Rotokakahi has one small spring-fed surface water inflow and one outflow, the Te Wairoa stream. Thus the lake is predominantly groundwater fed. The main objective of this thesis was to quantify the contribution of groundwater and surface water to Lake Rotokakahi and to examine interactions of the groundwater system with the lake, in order to provide a basis to improve lake management practices. Multiple monitoring sites were established around the perimeter of the lake to determine the spatial and temporal variation of groundwater inputs, as well as the groundwater nutrient dynamics. A three-dimensional hydrodynamic lake model was set up and simulations were used to examine how groundwater and surface water inflows were dispersed within the lake upon entry.

Monitoring of the shallow groundwater system took place from 1 January to 1 July 2016. Three separate storm events were monitored at high frequency within this monitoring period. The monitoring results showed the groundwater system varied significantly both spatially and temporally and also contributed a high proportion of the total nutrient load to the lake. Groundwater discharge and nutrient concentrations generally increased in association with or immediately following high rainfall events.
 
The three-dimensional model ELCOM was set up using hydrological data for the catchment, meteorological data from a nearby station and bathymetry of the lake. Simulations were based upon different methods of calculating groundwater inflows. Simulation 1 was based upon the common water balance equation method. Simulation 2 used constant groundwater inflow and outflow volumes as determined by a groundwater flow model, MODFLOW, which had been applied to the catchment by White et al., (2015). Simulation 3 combined MODLFOW values and measured groundwater levels to create a varying inflow volume based on water level. The three simulations accurately captured surface and bottom temperatures and had varying lake water levels. Only simulation 3 accurately captured the presence of the groundwater spring near the lake shore and was concluded the more accurate method of groundwater inflow calculation.
