title: Pinch Analysis Techniques for Carbon Emissions Reduction in the New Zealand Industrial Process Heat Sector

authors: Walmsley, Michael R.W.

abstract: Options for reducing industrial process heat greenhouse gas (GHG) emissions in New Zealand are investigated using the Carbon Emissions Pinch Analysis (CEPA) and Energy Return on Energy Invested (EROI) analysis methods. Renewable sources like geothermal, biomass, biogas from animal waste and heat pumps from renewable electricity are investigated. Results indicate that some regions of New Zealand are well placed to make significant reductions to process heat GHG emissions through shifting from fossil fuel heating to renewable heating without a large increase in energy expended or cost. Reducing GHG emissions below 1990 levels can be achieved by using wood waste and biomass in place of coal (33.3 PJ) and biogas from animal waste in place of natural gas (12.1 PJ) where high temperature heating is required (>90 °C), and renewable electricity driven heat pumps for low temperature heating (<90 °C) in dairy and meat processing industries (7.0 PJ). The expected increase in expended energy is 20 %. Over all the Central North Island of New Zealand has a significant degree of renewable and natural resource convergence and hence is a prime region for creating low carbon emission industries requiring process heat based on renewable energy and agricultural and forestry waste.

title: Women's contemporary yoga lifestyles: An embodied ethnography of becomings

authors: Jeffrey, Allison

subjects: Yoga

abstract: Within this thesis, I offer insight into the lifestyles of contemporary women Yoga practitioners. Delving into complex and nuanced experiences of women embodying Yoga lifestyles offers multiple opportunities to extend upon current understandings. In examining the various ways that the women of this study are navigating an increasingly popular movement culture that has foundations in ancient texts from India, I illustrate how today’s Yoga lifestyles are a cumulative expression of ancient and contemporary knowledges.

Moving alongside women practitioners throughout an embodied ethnographic study, I gained deep insights into the philosophies and practices of the women. Informed by the experiences of 19 women living in the Waikato region of Aotearoa/New Zealand through in-depth and informal interviews, observations, journals and focus groups, I offer rich, embodied knowledge from the women alongside my own creative writing. Engaging in feminist methods and in dialogue with yogic principles, I build an entangled ethnographic approach inspired by both the embodied philosophies of Yoga practitioners and contemporary feminist theory. Working at this intersection, I develop a mutually enriching research experience where multiple ways of knowing and a complex engagement with both theory and method can resonate. 

Findings are presented in three empirical chapters that demonstrate nuanced and complex understandings of women’s Yoga lifestyles. The first addresses the concept of lifestyle as understood by contemporary women Yoga practitioners. Drawing upon feminist lifestyles research, this chapter follows these women’s journeys as they claim and maintain Yoga lifestyles. The second chapter moves into a dialogue with feminist new materialisms, and in particular, Karen Barad’s (2007) concept of entanglement. I conceptualise an entangled Yoga body as always intra-acting and continually becoming. Using the women’s experiences, Barad’s concept, and evocative writing, I provide three examples (breath, Yoga mats and the heart) to represent an entangled Yoga body. The third and final empirical chapter weaves together recent work from Rosi Braidotti (2019) with insights from the women to contemplate the components of Yoga lifestyles as expressed by the women’s daily choices. This chapter suggests the women find meaning for their contemporary Yoga lifestyles through everyday ethically-informed acts contributing to an affirmative becoming. 

Moving, teaching and embodying Yoga philosophy as a researcher and experienced member of the Yoga community, I consider the complexity of the women’s lived experiences and my place amongst them. Inquiring deeply into questions around embodiment, materiality, and posthumanism, I develop an ethico-onto-epistemological stance that extends upon previous Yoga lifestyle research and contributes to the growing body of literature on women’s lived experiences in moving bodies.

title: Street health: Practitioner service provision for Māori homeless people in Auckland

authors: Nikora, Linda Waimarie

abstract: Homelessness is more than a transient crisis. While access to housing might solve the needs of some, research has shown that the needs of homeless people are much more complex and more a symptom of systematic structural inequalities than an unanticipated emergency (Hopper, 1998). As in other countries, the homeless population in New Zealand is made up of a diverse population of men, women and intersex groups of various ages, sexualities and ethnic backgrounds. Māori are over-represented among this population due to ongoing processes of colonisation and socioeconomic exclusion (Groot et al., 2011). When compared with domiciled citizens, homeless people are more likely to experience a raft of illnesses and unmet health needs, violence, a sense of insecurity, exclusion and fear, and are more likely to commit sui- cide (Hodgetts et al., 2007). Homeless people often experience diverse ill- nesses including asthma, heart disease, diabetes, hepatitis, renal disease, dermatological conditions, malnutrition, oral disease, depression, schizo- phrenia, substance misuse and broken bones (Ellison-Loschmann & Pearce, 2006; Joly et al., 2011; Moore et al., 2007).
