title: Mapping and explaining the productivity of Pinus radiata in New Zealand

authors: Palmer, Jonathan G.

abstract: Mapping Pinus radiata productivity for New Zealand not only provides useful information for forest owners, industry stakeholders and policy managers, but also enables current and future plantations to be visualised, quantified, and planned. Using an extensive set of permanent sample plots, split into fitting (n = 1,146) and validation (n = 618) datasets, models of P. radiata 300 Index (an index of volume mean annual increment) and Site Index (an index of height growth) were developed using a regression kriging technique. Spatial predictions were accurate and accounted for 61% and 70% of the variance for 300 Index and Site Index, respectively. Productivity predicted from these surfaces for the entire plantation estate averaged 27.4 m³ ha⁻¹ yr⁻¹ for the 300 Index and 30.4 m for Site Index. Surfaces showed wide regional variation in this productivity, which was attributable mainly to variation in air temperature and root-zone water storage from site to site.

title: Exploring Critical Alternatives for Youth Development through Lifestyle Sport: Surfing and Community Development in Aotearoa/New Zealand

authors: Wheaton, Belinda

subjects: Science & Technology

abstract: While competition-based team sports remain dominant in community and sport-for-development programs, researchers are exploring the value of alternative, less “sportized” activities such as lifestyle/action sports. In this paper, we explore the ways in which surfing is being used in development programs in Aotearoa/New Zealand, examining the perceived social benefits and impact. Our methods involved: (a) mapping the range of surfing projects; and (b) 8 in-depth interviews with program personnel. Widespread conviction in the positive developmental benefits of surfing was evident, and that surfing had a “special” capacity to reform or heal those who participate in it. However, the ways in which individuals’ self-developments were promoted appear to be following the traditional sport/youth development path. They focus on policies aimed at improved life chances, equipping youth with the tools for self-improvement and self-management, inculcating self-governance and self-reliance. However, a counter narrative co-existed, highlighting surfing as a freeing experience, which, rather than restoring social order, works to instigate a personal transformation or awakening. Despite the range of challenges presented by surfing as a tool for positive development, surfing presents a potentially “critical alternative” which if sport-for-development programs are to be a form of social change, we should remain open to exploring.

title: A Māori Perspective of Whānau and Childrearing in the 21st Century Case Study

authors: Morehu, Colleen

subjects: childrearing

abstract: Ngā Kupu Whakataki: Abstract

The study focuses on identifying how the reconstruction of the whānau and its approach to childrearing through the colonisation of Māori society can be perceived within the experiences of the case study of four generations of one whānau.  A kaupapa Māori approach to research provided a framework for members of our whānau to socially construct their realities regarding the dynamics of our four generation whānau collaboratively.  Socio-cultural theoretical frameworks were used to analyse approaches to whānau and childrearing.
