title: Walking into the past to explore the future: Utulizing larval densities to measure the effects of two climate change factors, temperature and salinity on Poorohe (common smelt, Retropinna retropinna) abundance in Te Puuaha o Waikato

authors: Robcke, Sidney

subjects: Common smelt

abstract: Poorohe (common smelt, Retropinna retropinna) are a highly valued kai species in Te Puuaha o Waikato (the lower 66 km of the Waikato River). Fisher whaanau have observed changes in the amount Poorohe that are harvested during annual fish harvests. Since Poorohe are particularly vulnerable to environmental changes, whaanau are particularly concerned about the how climate change might impact Poorohe populations. Climate change vulnerability assessments (CCVA) currently exist for several native New Zealand fish freshwater species; however, one does not yet exist for Poorohe. Previous larval distribution studies in the lower Waikato River only sampled as far downstream as Tuakau bridge (approximately 45km from the river mouth). These studies indicated that important spawning habitats likely existed downstream of Tuakau bridge. Temperature increases and saltwater intrusion have been identified as two climate change factors that will likely impact Poorohe in Te Puuaha o Waikato, because ambient temperatures have increased since the industrial revolution and the proximity of the study area to the ocean. A literature review was used to explore the experiences of fisher whaanau through the past, present and how the experiences will continue to change in a changing climate. The effects of temperature and saltwater intrusion on Poorohe populations were explored through replicating the methods of past research carried out in the 1980s and 2010s. Current river temperatures are in the optimal temperature range (12°C - 18°C) for Poorohe spawning. The saltwater wedge was suppressed by the high river flow during the eight-week sampling period, and it is unclear whether saltwater intrusion has an impact on Poorohe spawning. Larval densities did not significantly increase down river, which suggests large spawning habitat is not found downstream of Tuakau bridge. Furthermore, there were no decreases in larval densities in the two saltwater sites. This study has contributed to the available literature necessary to develop a CCVA for Poorohe and explored the cultural heritage of traditionally significant practices in Te Puuaha o Waikato relating to Poorohe.

title: Education leaders can reduce educational disparities

authors: Bishop, Russell

subjects: education

abstract: This chapter is about how education leaders can act to reduce educational disparities for indigenous and other minoritized peoples through strategic goal setting, supporting effective pedagogies of relations, promoting distributed leadership, enacting inclusivity, using evidence and owning the need for reform. Examples are drawn from a large-scale, theory-based education reform project called Te Kotahitanga which is currently running in 50 secondary schools in New Zealand. Developing a model for effective leadership needs to commence with the understanding that the key to change is teacher action supported by responsive structural reform (Elmore 2004). In our earlier work (Bishop et al. 2003, 2007) we investigated what effective teacher action looks like. This chapter presents a model of what “responsive structural reform” looks like in practice and what leaders need to do to implement and sustain gains made in student performance at the classroom, school and system-wide levels.

title: Why case study research? Introduction to the field guide to case study research in tourism, hospitality, and leisure

authors: Hyde, Kenneth F.

abstract: This chapter is a general introduction to the field of case study research in tourism, hospitality, and leisure. The chapter presents a brief review of the literature on the intra-individual logic of case study research. The chapter describes the “four horsemen” for doing case study research: accuracy, generality, complexity/coverage, and value/impact. Examples in the chapter that illustrate this perspective for undertaking case study research may impassion the reader to read through the field guide and personally engage in case study research – at least that is the hope of the editors of this field guide.
