    Flourishing together: research protocol for developing methods to better include disabled people's knowledge in health policy development
    (BioMed Central Ltd, 2022-12) Martin RA; Baker AP; Smiler K; Middleton L; Hay-Smith J; Kayes N; Grace C; Apiata TAM; Nunnerley JL; Brown AE
    BACKGROUND: To positively impact the social determinants of health, disabled people need to contribute to policy planning and programme development. However, they report barriers to engaging meaningfully in consultation processes. Additionally, their recommendations may not be articulated in ways that policy planners can readily use. This gap contributes to health outcome inequities. Participatory co-production methods have the potential to improve policy responsiveness. This research will use innovative methods to generate tools for co-producing knowledge in health-related policy areas, empowering disabled people to articulate experience, expertise and insights promoting equitable health policy and programme development within Aotearoa New Zealand. To develop these methods, as an exemplar, we will partner with both tāngata whaikaha Māori and disabled people to co-produce policy recommendations around housing and home (kāinga)-developing a nuanced understanding of the contexts in which disabled people can access and maintain kāinga meeting their needs and aspirations. METHODS: Participatory co-production methods with disabled people, embedded within a realist methodological approach, will develop theories on how best to co-produce and effectively articulate knowledge to address equitable health-related policy and programme development-considering what works for whom under what conditions. Theory-building workshops (Phase 1) and qualitative surveys (Phase 2) will explore contexts and resources (i.e., at individual, social and environmental levels) supporting them to access and maintain kāinga that best meets their needs and aspirations. In Phase 3, a realist review with embedded co-production workshops will synthesise evidence and co-produce knowledge from published literature and non-published reports. Finally, in Phase 4, co-produced knowledge from all phases will be synthesised to develop two key research outputs: housing policy recommendations and innovative co-production methods and tools empowering disabled people to create, synthesise and articulate knowledge to planners of health-related policy. DISCUSSION: This research will develop participatory co-production methods and tools to support future creation, synthesis and articulation of the knowledge and experiences of disabled people, contributing to policies that positively impact their social determinants of health.

    He Kāinga Oranga: reflections on 25 years of measuring the improved health, wellbeing and sustainability of healthier housing
    (Taylor and Francis, on behalf of Te Aparangi, The Royal Society of New Zealand, 2023-02-06) Howden-Chapman P; Crane J; Keall M; Pierse N; Baker MG; Cunningham C; Amore K; Aspinall C; Bennett J; Bierre S; Boulic M; Chapman R; Chisholm E; Davies C; Fougere G; Fraser B; Fyfe C; Grant L; Grimes A; Halley C; Logan-Riley A; Nathan K; Olin C; Ombler J; O’Sullivan K; Pehi T; Penny G; Phipps R; Plagman M; Randal E; Riggs L; Robson B; Ruru J; Shaw C; Schrader B; Teariki MA; Telfar Barnard L; Tiatia R; Toy-Cronin B; Tupara H; Viggers H; Wall T; Wilkie M; Woodward A; Zhang W
    This paper reflects on the influences and outcomes of He Kāinga Oranga/Housing and Health Research Programme over 25 years, and their impact on housing and health policy in Aotearoa and internationally. Working in partnership particularly with Māori and Pasifika communities, we have conducted randomised control trials which have shown the health and broad co-benefits of retrofitted insulation, heating and remediation of home hazards, which have underpinned government policy in the Warm Up NZ-Heat Smart programme and the Healthy Homes Standards for rental housing. These trials have been included as evidence in the WHO Housing and Health Guidelines and led to our designation as a WHO Collaborating Centre on Housing and Wellbeing. We are increasingly explicitly weaving Māori frameworks, values and processes with traditional Western science.

    Evolutionary Game and Simulation of Green Housing Market Subject Behavior in China.
    (John Wiley and Sons, 2022-04-05) Qian Y; Yu M; Wang T; Yuan R; Feng Z; Zhao X; Fu H
    In China, driven by the national "3060" double carbon targets (i.e., reaching peak carbon emissions by 2030 and carbon neutrality by 2060), green housing has become one of the major fields to reduce carbon emissions, facilitating the achievement of the double carbon targets. Promoting the growth of green housing is an important way for the real estate industry to achieve low-carbon transformation and improve the quality of housing. Meanwhile, the construction industry also can benefit from green housing to achieve its energy conservation and emission reduction targets. Therefore, it is critical to boost and maintain the sustainable growth of the green housing market in China. However, the literature has not focused attention on the market behavior of the green housing market in China. This study proposes a tripartite evolutionary game model to investigate the subject behavior of the green housing market in China. This model consists of three major subjects in a green housing market: developers, consumers, and governments. Based on this model, this study analyzes the stability of the strategy options for each stakeholder and identifies the stable conditions of strategy portfolios to reach the equilibrium points of the game system. The validity of the proposed tripartite evolutionary game model is tested through the simulation of the impacts from various factors on system evolution. According to the impacts of factors and the stable conditions of strategies, this paper puts forward relevant policy suggestions for the healthy and sustainable growth of China's green housing market.

    The impact of residential property investors on house price escalation in Auckland, New Zealand : research report in fulfillment of the requirements for Doctor of Philosophy in Property, School of Economics and Finance, Massey University, New Zealand
    (Massey University, 2024-07-24) White, David Jon
    Affordability and home ownership in Auckland New Zealand has been in decline over the past decade. Since the Global Financial Crisis in 2008, house affordability has decreased at an unprecedented rate, largely attributed to house price escalation with some mitigation from wage growth and interest rate decreases. The decline in the affordability of owner-occupation compared to renting has been particularly pronounced in Auckland and this has led to a decline in home ownership and political interest in the role of investors that could contribute to price escalation. This perceived role of investors has resulted in policy changes aimed at discouraging speculation. This research investigates the pricing decisions of investors in the Auckland housing market and the link to house price escalation and affordability of housing. This research investigates whether this sustained escalation in prices can be explained by bounded rationality in pricing decisions by comparison to a normative model. The methodology adopted is a mix of qualitative and quantitative methods. Qualitative methods are used to gather the stated preference of investors in relation to their investment motivations and pricing decisions was obtained via structured interviews with investors and institutional influencers, with reference to behavioural economic concepts and frameworks. Quantitative methods are used to quantify at the aggregate market level the deviation from normative pricing, and to quantify for explanatory purposes those components of pricing decisions that contribute to overpricing, using the user-cost equilibrium model. It is concluded that investors are inclined to over-price houses compared to what is predicted by a normative model, largely due to an over-estimation of capital gain expectations and an under-estimation of systemic risks. This over-estimation of capital gain expectation is self-reinforcing and leads to sustained over-pricing which influences the market in aggregate and therefore house price escalation.

    The social construction of housing tenure in Aotearoa New Zealand, 1900 to 1990 : crisis, place, and the path to a dual tenure regime : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Geography at Massey University, Manawatū, Aotearoa New Zealand
    (Massey University, 2023) Ryland, Daniel Brian
    Over the 20th Century and beyond there have been repeated urban housing crises which have negatively impacted the welfare of many households. Discussions and solutions for these crises have centred on binaries of homeownership and renting or State versus market within a pre-determined housing trajectory. However, the academic housing literature has argued for a more nuanced view of tenure to engage with housing effectively. This thesis aims to contribute to this project by exploring Aotearoa New Zealand’s pathway toward a dual tenure regime. I explore tenure as a relational concept created by the intersection of economic, legal, and cultural dimensions in place and across time. Exploring tenure beyond broad categorisations emphasises the need to imagine it differently. I used document analysis drawing on Parliamentary debates, political cartoons, archival documents, newspapers, statistics, and community organisation reports. They were analysed with a social constructivist approach inspired by a critical realism lens to explore the interdependence of tenure, place, and housing crisis. A core feature is that housing crises necessitating solutions drive tenure change. To explore Aotearoa New Zealand’s pathway to a dual tenure regime, I focused on the social construction of tenure during three housing crises. I argue that Aotearoa New Zealand’s dual tenure regime valorising freehold ownership with an individual title over other tenure options took shape over the 20th Century. Housing policy and economic decisions in the first quarter of the century to deal with housing crises embedded freehold ownership with an individual title as the most desirable tenure and end point of a housing trajectory. These would be reinforced through later housing crises as the social construction of tenure created opportunities and constraints for housing. By 1990, tenures were understood through their relation to freehold with an individual title and how they fit within a pre-defined housing trajectory, limiting the ability to experiment with other tenure forms. The thesis concludes that tenure needs to be imagined holistically as a multiply-determined, dynamic, and relational concept intertwined with crises, and that the latter can highlight opportunities to imagine other tenures.

    Measuring hoof horn haemorrhage in heifers: A history.
    (Elsevier B.V., 2024-06-27) Laven R; Laven L
    Understanding the aetiology and pathogenesis of claw-horn disease (CHD) is essential for developing prevention/treatment programmes. Haemorrhages in the hoof horn (i.e. white line/sole haemorrhages) are an important part of the pathogenesis of CHD, being precursors to and predictors of lesions such as white-line disease and sole ulcer. Understanding haemorrhage development can provide useful information about the aetiology and pathogenesis of CHD. The development of hoof horn haemorrhages is best studied in cattle without previous claw-horn damage, as previous history of damage can markedly alter the hoof's response to stressors. Since the early 1990s, many prospective studies of the risk factors associated with CHD have been undertaken in late pregnant and early lactation heifers, which have a low risk of having had CHD but which are exposed to the same risk factors as lactating cows. Those studies have used a range of methods to assess hoof horn haemorrhages, with the principal focus, particularly initially (but also more recently), being on measuring lesion severity. However, as the science developed it became clear that measuring lesion extent was also important and that combining severity and extent in a single measure was the best approach to assess hoof horn haemorrhages. Studies of hoof horn haemorrhage in heifers have significantly increased our understanding of CHD, demonstrating the importance of housing and the relative lack of importance of post-calving nutrition. Most importantly, they have shown the importance of parturition as a risk factor for CHD, and how parturition interacts with other risk factors to accentuate their effect. The use of such studies has decreased in recent years, despite recent research showing that we still have much to learn from prospective studies of hoof horn haemorrhages in heifers.

    Inequities in adolescent sleep health in Aotearoa New Zealand: Cross-sectional survey findings.
    (Published by Elsevier Inc. on behalf of National Sleep Foundation, 2024-06-22) Muller D; Signal TL; Shanthakumar M; Fleming T; Clark TC; Crengle S; Donkin L; Paine S-J
    OBJECTIVES: To investigate ethnic inequities in, and social determinants of, adolescent sleep health in Aotearoa New Zealand. METHODS: Analysis of self-report data from a cross-sectional survey of secondary school students (12- to 18-year-olds). Analyses included weighted prevalence estimates of good and poor sleep health stratified by ethnicity, and multivariable logistic regression models concurrently adjusted for ethnicity, school year, gender, rurality, neighborhood deprivation, school decile, housing deprivation, sleeping elsewhere due to lack of adequate housing, unsafe environment, and racism. RESULTS: Inequities in social determinants of health were evident for Māori (Indigenous peoples of Aotearoa New Zealand; n = 1528) and minoritized (Pacific n = 1204; Asian n = 1927; Middle Eastern, Latin American, and African [MELAA] n = 210; and 'Other' ethnicity n = 225) adolescents. A greater proportion of Māori, Pacific, Asian, MELAA, and 'Other' adolescents had short sleep, compared to European (n = 3070). Māori, Pacific, Asian, and MELAA adolescents were more likely to report late bedtimes (after midnight), and Māori, Pacific, and 'Other' adolescents were more likely to report early waketimes (5 AM-6 AM or earlier), on school days. Rurality, neighborhood deprivation, school-level deprivation, housing deprivation, sleeping elsewhere due to inadequate housing, unsafe environments, and racism partially, but not fully, explained associations between ethnicity and short sleep, late bedtimes, and early waketimes. CONCLUSIONS: Ethnic inequities exist in adolescent sleep health in Aotearoa New Zealand. Socio-political actions are needed to address racism and colonialism as root causes of ethnic inequities in adolescent sleep, to ensure all young people are afforded the basic human right of good sleep health and associated mental and physical well-being.

    Essays on China's real estate market : a thesis presented in fulfilment of the requirement for the degree of Doctor of Philosophy in Economics at Massey University, Manawatu Campus, New Zealand
    (Massey University, 2024-04-10) Mao, Yiran
    This thesis examines the factors that affect the real estate market in China from the perspectives of sentiment, place-based policies, and tariff shocks. The results are presented in three stand-alone empirical chapters. Chapter 2 probes the influence of sentiment on house prices within China. We construct a novel social media sentiment index, which quantified the tone of Weibo posts relating to "housing market'' from 2010 to 2020 across China's 35 largest cities. This index can predict house price changes up to six quarters ahead, even after factoring in economic fundamentals. These findings, robust to numerous checks, are not driven by announced policy modifications, unobserved fundamentals, or censorship bias and therefore reinforce theories of social learning and, to a minor degree, of animal spirits. Chapter 3 investigates the impact of the merger of suburbs into urban districts on property prices, using Beijing as an example and utilizing a difference-in-differences approach, within an event study framework. The results show that such mergers lead to a substantial surge in house prices in the rezoned areas. In contrast, the non-rezoned border districts experience a decline, with localized impacts in both scenarios. The merger negatively affects the economically disadvantaged, evident by the pronounced decline in house prices for low-priced properties in non-rezoned border districts and a smaller increase in rezoned ones. Further analysis reveals that the merger has a positive spillover effect in surrounding counties, with the effect decreasing as the distance to the rezoned districts increased. Chapter 4 analyzes the impacts of the US-China tariff war on commercial building rents across Chinese cities using Bartik-style tariff exposure proxies. This analysis finds a one percentage point increase in the US tariff exposure resulted in a 1.03 percent decrease in commercial building rent growth after one quarter, ceteris paribus. In contrast, China's retaliatory tariff has no significant impact on the growth of commercial building rents. Additionally, the analysis reveals differences in rent responses, with areas of elevated US dependence showing intensified detrimental effects, while superior financial conditions, societal stability, innovation, and geographical placement showing mitigated effects. Furthermore, the chapter reports that tariff exposures from the US and China exerted their influences through different channels, subtly affecting rent growth. The insights derived from this thesis are pivotal for policy formulation in developing nations. Firstly, sentiment, prominently reflected through social media, exerts a tangible and foreseeable impact on real estate valuations. This indicates that policymakers should monitor public sentiment as a precursor for probable escalations or depreciation in property markets. Secondly, urban planning and rezoning decisions can induce significant impacts on housing values in local and neighboring markets. Thus, it is imperative for policymakers to judiciously evaluate the implications of such initiatives, particularly their repercussions on less affluent demographics. Lastly, external economic disruptions, like the US-China tariff war, can profoundly influence commercial real estate rents, especially those cities intertwined with international trade. The adverse effects are palpable in both China and the US, indicating a need for policymakers to fortify the robustness of property markets against external perturbations by diversifying economic partnerships and instituting provisional strategies.

    Older People’s Neighborhood Perceptions Are Related to Social and Emotional Loneliness and Mediated by Social Network Type
    (Oxford University Press, 2022-10-19) Stephens C; Phillips H
    Background and Objectives Loneliness among older people is a public health issue; however, there is very weak support for the efficacy of individually focused interventions. A public health model, which includes the environmental influence on the formation of social networks and protection from loneliness, and theoretical approaches differentiating between social and emotional loneliness, suggest the importance of neighborhoods in preventing loneliness. This approach was used to test the influence of neighborhood factors on loneliness and the mediating role of social networks. Research Design and Methods A questionnaire survey of 917 people aged 60–100 years was conducted in one region of Aotearoa/New Zealand to assess loneliness, social network types, social participation, marital status, gender, health, and four aspects of neighborhood perceptions. Results Social and emotional loneliness scores were regressed on predicted demographic and social variables, followed by perceptions of Housing Satisfaction, Neighborhood Accessibility, Neighborhood Security, and Neighborhood Social Cohesion. Neighborhood variables added significant explanation of variance in both social and emotional loneliness. Mediation tests using PROCESS showed that the effects of all neighborhood variables were mediated by Private-Restricted or Locally Integrated Network types on Social Loneliness only. Discussion and Implications These findings highlight the importance of neighborhood factors in relation to feelings of loneliness and the recognition of social network types as mediators of these relationships for social loneliness. The aspects of neighborhoods that prevent loneliness provide directions for planners and prevention programs. Interventions to prevent social loneliness can usefully and practicably focus on the housing and neighborhood environment.

    Lessons from the implementation of residential methamphetamine contamination policies in New Zealand
    (John Wiley & Sons Australia, Ltd on behalf of Australasian Professional Society on Alcohol and other Drugs, 2023-03) Sanchez Lozano CD; Wilkins C; Rychert M
    Introduction Methamphetamine contamination of housing has been discussed as a significant issue in New Zealand. However, scientific evidence to determine a threshold level at which health harms occur is inconclusive, resulting in conflicting and changing guidance. The initial strong precautionary policy, with significant unintended impacts on vulnerable public housing tenants, dramatically changed following a scientific review. This study explores the policy response to residential methamphetamine contamination in New Zealand over the past decade. Methods Thematic analysis of semi-structured interviews with 13 key stakeholders involved in policy development/implementation, including those from government, industry, residential housing and academic sectors. Results Consistent application of a methamphetamine contamination threshold for housing has been problematic due to legislative and regulatory gaps. Stakeholders in the residential sector have been influenced by perceptions of methamphetamine contamination as a health risk, political views on drug use, media coverage and the testing industry's business practices. Public housing tenants have faced disadvantages when resolving methamphetamine contamination disputes. The testing industry's participation in committees shaping the regulatory response presents a possible conflict of interest. Wide media coverage heightened public anxiety about the problem but may also have stimulated policy changes to alleviate unintended consequences of the precautionary approach. Discussion and Conclusions New Zealand's fragmented policy response to residential methamphetamine contamination is likely rooted in the lack of scientific evidence, with some key actors further exacerbating the response. Future policy development should seek to produce overarching regulation that guides the whole sector while balancing powers of the stakeholders involved.
