title: Age-related changes in physical and perceptual markers of recovery following high-intensity interval cycle exercise

authors: Borges, Nattai R.

subjects: Science & Technology

abstract: Background: The purpose of this study was to compare physical performance, perceptual and haematological markers of recovery in well-trained masters and young cyclists across 48 h following a bout of repeated high-intensity interval exercise.

Methods: Nine masters (mean ± SD; age = 55.6 ± 5.0 years) and eight young (age = 25.9 ± 3.0 years) cyclists performed a high-intensity interval exercise session consisting of 6 × 30 s intervals at 175% peak power output with 4.5 min rest between efforts. Maximal voluntary contraction (MVC), 10 s sprint (10SST), 30-min time trial (30TT) performance, creatine kinase concentration (CK) and perceptual measures of motivation, total recovery, fatigue and muscle soreness were collected at baseline and at standardised time points across the 48 h recovery period.

Results: No significant group-time interactions were observed for performance of MVC, 10SST, 30TT and CK (P > 0.05). A significant reduction in 10SST peak power was found in both masters (P = 0.002) and young (P = 0.003) cyclists at 1 h post exercise, however, both groups physically recovered at similar rates. Neither group showed significant (P > 0.05) or practically meaningful increases in CK (%∆ < 10%). A significant age-related difference was found for perceptual fatigue (P = 0.01) and analysis of effect size (ES) showed that perceptual recovery was delayed with masters cyclists reporting lower motivation (ES ±90%CI = 0.69 ± 0.77, moderate), greater fatigue (ES = 0.75 ± 0.93, moderate) and muscle soreness (ES = 0.61 ± 0.70, moderate) after 48 h of recovery.

Conclusion: The delay in perceived recovery may have negative effects on long-term participation to systematic training.

title: A critical appraisal of the concept of ecological modernisation: a case study from New Zealand’s dairy industry

authors: Jay, Grace Mairi M.

subjects: New Zealand dairy industry

abstract: The New Zealand dairy industry faces political and commercial pressure to improve its environmental performance while maintaining commercial competitiveness in a global marketplace. In response to such pressures, the industry has taken some steps to improve the environmental management practices of dairy farmers. Despite significant effort, however, the dairy sector remains highly influenced by global competition, and continues to subordinate environmental sustainability to economic productivity. Furthermore, government institutions have had limited control over farm management practices, or the extent to which public policies militate against the relentless rise in land use intensification.

title: E Whakatipuranga o te Tāpoi Māori - Māori Indigenous Tourism Development: A Whānau based Māori Tourism development

authors: Puriri, Ashley Reed

subjects: Maori Tourism

abstract: This Doctoral thesis uses a Kaupapa Māori research methodology, which is culturally grounded to identify the indigenous Māori underpinnings and processes that a Whānau (Māori family) experience when developing their Māori tourism business. The thesis discusses the following four issues, which are addressed using a Kaupapa Māori research methodology:
1. The gap in the current literature for Māori tourism development and authenticity from a Māori perspective.
2. The cultural underpinnings and processes of a Whānau (Māori family) tourism business.
3. Identification of the Māori cultural values that inform Māori tourism development
4. Development of a cultural framework that positions Māori values on levels of significance from a Māori perspective.
A cultural tourism experience is investigated, involving a Whānau Māori tourism business developed from a conceptual stage in preparation for financial investment. Using a Kaupapa Māori research methodology this research contributes to a gap in the academic literature relating to Whānau (Māori family) tourism development. The research contributes new academic literature to support the notion that the Whānau unit is at the core of social and economic development for Māori tourism. This thesis captures and describes the various stages, developed over a year, of Whānau Hui (family meetings), of a Whānau tourism business. As a Māori researcher, I gained emancipated access to a Whānau using Kaupapa Māori methods, applying a cultural set of protocols and values to unlock access to a Māori worldview of how a Whānau navigates the processes of developing their Whānau tourism experience in New Zealand. The engagement of a Kaupapa Māori research methodology enabled me to apply my personal skills of a lifetime of knowledge of Te Ao Māori (a Māori worldview) and Te Reo Māori (Māori language) combined with over 20 years of global advancement of indigenous tourism in the cruise industry. As a Tohunga Whakairo (master carver) I applied seven distinctive steps of a master carver’s processes in carving a Pou Tokomanawa (the main centre post of a Tipuna Whare orancestralmeeting house), providing a unique cultural process that frames the chapters of this dissertation. The research data provided an enriched flow of cultural information, which was analysed using a cultural analytical process to validate the key themes that emerged from the research findings. The cultural analyses are completed in two stages; the processes of Whakapapa and Whanaungatanga (cultural relationships), which are culturally-grounded methods for analysing research data using a Māori worldview, and the validation of cultural significance by Kaumātua (elders) of the Whānau. The thesis is imbued with cultural paradigms that frame and identify the cultural underpinnings and processes of a Whānau tourism development. The study expands on two cultural models,‘Te Tāpoi Poutama’ and Te Matua Poutama (Māori tourism frameworks for identifying cultural levels of significance) and these cultural paradigms are applied to demonstrate cultural levels of significance that a Whānau place on their proposed Māori tourism business.
