title: Teacher change in a developing curriculum area: the example of trade teachers in the New Zealand technology curriculum

authors: Jones, Alister

abstract: Technology education for all students is a relatively new phenomenon in national and international curricula. Although New Zealand has a long history of technical education in the senior primary and secondary school, a curriculum for technology education for all students has only recently been introduced. Aspects of technology have been included in many existing school programmes, but these have not been presented and undertaken in a coherent way. Technology as it developed in past curricula encompassed a limited range of skills, processes and knowledge. The general aims of technology education in Technology in the New Zealand Curriculum (Ministry of Education, 1995) are to develop  technological knowledge and understanding, an understanding and awareness of the interrelationship between technology and society, and technological capability  in a number of technological areas. This paper will report on the changes that a group of traditional technical teachers have been required to undergo and the way in which these teachers have, or have not, been successful in adapting to a new technology curriculum. The influences on this particular group will be explored, as well as the factors that have led to some of these teachers adopting the technology.

title: Counting Errors: How Misunderstanding of China's Local Population and Employment Counts Affects Economic Analysis

authors: Li, Chao

subjects: China

abstract: A confusion over local population counts and employment counts in China persists throughout the economic literature. The existing studies within many branches of economics related to China commonly use the count of people with local hukou registration, the GDP per capita using the hukou count as the population denominator, and incomplete employment counts reported in various Chinese statistical yearbooks as if they were appropriate measures of local population, local employment and local per capita income. This misunderstanding of China’s local population and employment counts may lead researchers astray and could contribute to wrong conclusions and mistaken policy implications. An analogous error would be to study the economic geography of, say, the United States using local population and employment counts that were only for citizens rather than for all residents; the resulting statistical pictures are likely to be biased since cities such as New York or Los Angeles have a much higher share of non-citizens than do other areas. Yet there is no similar criticism of the large and growing literature that relies on sub-national population counts for China, despite the equally egregious errors that are likely to have resulted from using the wrong population and employment counts.
	Five economic issues that are pertinent to modern China are studied in this thesis using the most reliable estimates of local resident population and employment from China’s 2010 population census. These issues are regional inequality, optimal city size, the city size distribution, the nature, location and size of urbanization economies, and the determinants of urban land area expansion. Each issue is studied in a single, self-contained, paper that in some cases has already appeared in a peer-reviewed journal, and in other cases is under review at such journals. In general, the findings based on the most reliable local resident population counts and employment counts from the 2010 census extensively challenge the existing evidence in the literature. In some cases the policy implications from this new research are the opposite of what was previously suggested from research that was potentially distorted by the counting errors described here.

title: Ethnobotany, germination and growth of eleocharis sphacelata

authors: Kapa, Mieke M

subjects: Eleocharis

abstract: Eleocharis sphacelata, distributed over Australia, Papa New Guinea and predominantly in the north of the North Island New Zealand, occupies the littoral margins of fresh water wetlands and lakes. To assist Eleocharis sphacelata revegetation efforts, research recorded traditional ecological knowledge held by users, determined best methodologies for germination of seed, and established techniques for improved transfer of juvenile plantlets. 
Interviews with cultural knowledge holders revealed a declining but persistent oral repository in tikanga (customs) and practices despite diminishing plant availability. Eleocharis sphacelata has traditionally and contemporarily been used as a fibre for weaving into mats, with its spongy pith providing increased warmth and comfort. Group harvesting, with some cutting and others sorting and binding is the first step in a short preparation sequence, with the drying of the stems (for most this is in the shade) the only other preparation needed before weaving commences. Cultural genealogical descriptions provide a clear portrait of the ecological position Eleocharis sphacelata sits within its natural habitat and presents a phylogeny or schemata comparable to biological science. Published information identifies cultural uses and practices for the fibre of this wetland sedge. 
Fresh and stored seeds were subjected to five treatments at three water levels to determine the best methodology for increased germination rates. Findings illustrate how a scarification pre-treatment and water depth increases up to 15 cm enhances germination rates of Eleocharis sphacelata. Overnight bleaching of seed harvested one month earlier (January 2008) then sown under damp conditions provided increased germination until April. Fresh bleached seed sown under 5 cm and 15 cm of water produced significant increases in germination from September. Seasonal timing and variation in water depth as germination triggers indicate dual germination strategies employed by Eleocharis sphacelata.
In November 2007 seed grown seedlings and vegetative propagules were planted in situ under three water depths to establish which plantlet type would provide increased juvenile survival when used in revegetation projects. Findings determined that seed grown seedlings planted under 15 cm of water had the highest survival and produced a greater number of culms per plantlet, however vegetative propagules were better able to survive in damp conditions. Flowering occurred in over 25% of remaining vegetative and seed grown seedlings by the following October indicating the potential for new transfers to be reproducing within one season. 
Further collaborating between Māori and western science would augment and enhance understanding of transferable environmental methodologies. Possible dual germination strategies by the seed were revealed and further research would determine if this replicates the reproductive and growth capabilities of Eleocharis sphacelata and other wetland sedges in their natural environment. Additional seed quality and technological research would increase potential for seed performance. Determining genetic variety within local, regional and national Eleocharis sphacelata swards would establish bounds of local provenance.
