title: Designing a low cost solar collector system for process industry applications

authors: Anderson, Timothy Nicholas

subjects: New Zealand

abstract: New Zealand is a large producer and processor of primary products and has a climate with high levels of solar radiation. However, the use of solar energy for heating and cooling in the processing industries has received limited attention. 
For this study, the design of a low cost solar collector is analysed and discussed. Furthermore, the methods for integrating the collector into water heating and cooling systems in a hypothetical processing environment are examined. An F-Chart analysis is used to simulate the performance of large-area arrays of the solar collector and to determine its potential contribution to heating and cooling loads. 
The study shows that for a storage-based system, the contribution of solar energy is determined mainly by the collector area to storage volume ratio. It is suggested that this low cost collector could make a significant contribution to energy use in processing plants and may be an attractive future technology.

title: Harnessing the private sector for rural development, poverty alleviation and HIV/AIDS prevention

authors: Lim, Steven

subjects: rural development

abstract: In resource-constrained developing countries, mobilizing resources from outside sources may assist in overcoming many development challenges. This paper examines the Thai Business Initiative in Rural Development (TBIRD), an NGO-sponsored program that brings together the comparative advantages and self-interest of rural villages, private sector firms and a facilitating NGO, to improve social and community health outcomes in rural areas. We analyze key issues in the program with data from Northeast Thailand. We find that the TBIRD program appears to improve the income earning and other prospects of the TBIRD factory workers. Further, TBIRD factory employment exhibits a pro-poor bias. A key impact is to provide jobs for people who might otherwise be at increased risk of HIV infection through poverty-induced decisions to migrate to urban centres and participate in the commercial sex industry. This program adds another important tool for development planners in the fight against HIV/AIDS.

title: Hauora and physical education in New Zealand: perspectives of Māori and Pasifika

authors: Fitzpatrick, Katie

subjects: physical education

abstract: Discussion surrounding the concept of Hauora (Durie, 1994) in the document Health and Physical Education in the New Zealand Curriculum (Ministry of Education, 1999) has been controversial. Some writers have praised or justified its inclusion (Culpan, 1996/1997; Tasker, 1996/1997; Tinning, MacDonald, Wright & Hickey, 2001), while others accuse the writers of tokenism and misappropriation of indigenous knowledge (Hokowhitu, 2004; Salter, 2000). While existing at a political level, these debates have generally ignored student responses to and interactions with Hauora. Thus, this article intervenes in the existing debate and makes the case for the inclusion of student perspectives. My claims are made on the basis of a study into the perspectives of Māori and Pasifika students of physical education in New Zealand. The experiences of these students are related to the theory of hybridity (Besley, 2002; Bhabha, 1994), which suggests that young people actively negotiate and make critical decisions about what they think is relevant to them. I argue that the debate surrounding the concept of Hauora needs to include students' perspectives and consideration of the agency of young people in interactions with curriculum concepts.
