title: Volatility and skewness spillover between stock index and stock index futures markets during the crash period: New evidence from China

authors: Hou, Yang (Greg)

subjects: Volatility Spillover

abstract: This paper examines volatility and skewness spillover between the Chinese stock index and index futures markets during a market crash in 2015. The volatility spillover from futures to spot is significant and stronger than the other way around. Moreover, the transmission of downside risk is bilateral with the futures market taking the lead. It is revealed that measures announced during the market crash to curb the speculative futures trading enhance the spillover of both volatility and skewness from futures to spot markets. This finding sheds light on validity of such measures to restore market efficiency during a stock market crash.

title: “It’s a case of access.” The problematics of accessing research participants

authors: Amundsen, Diana Leigh

subjects: Gatekeepers

abstract: The problematics of accessing res participants have been largely under-stated in the education research literature. This article discusses two case studies which illustrate the complexity of the process of access. This is complexity beyond ethical consent; it is the complexity of gaining access to research sites and participants and of ongoing negotiation concerning aspects of access, especially when the stakes are high for participants. In this article we first set out what is already known in the literature about challenges and strategies of access. Next, we evaluate our own experiences of access with others. Our analysis reveals key findings: a) the relevance of insider/outsider status; b) the need to engage in repeated negotiations to obtain the agreement and consent of gatekeepers; c) the value of identifying kaiārahi (guides) and building relationships; d) the importance of understanding organisational culture, power dynamics of relationships and of knowledge production; and e) the significance of operating in a transparent manner around researcher identity and the nature of the specific study. A research plan may be approved as ethical but may not prove to be practical when the researcher tries to enact it, thus necessitating modification. The challenge becomes finding a practice that is ethical for a particular group and context. Lastly, we propose that education researchers who have negotiated the power dynamics to build relationships among kaiārahi, gatekeepers and participants need to communicate their knowledge and experiences of accessing research participants with other researchers.

title: Haumanu hauora: A commentary on strengthening health institution responsiveness to Māori health in the face of climate change

authors: Masters-Awatere, Bridgette

abstract: Climate change is the biggest threat to humanity through compounding ecological disasters. A focus on global averages tends to hide dramatic differences and mask health disparities that exist for Indigenous people. For 21 years, district health boards (DHBs) were responsible for providing or funding the provision of health services across Aotearoa. The introduction of the Pae Ora (Healthy Futures) Act 2022 disestablished DHBs and offered an opportunity to reshape health in ways that give serious consideration to climate change impacts. The need to give greater consideration to Indigenous people in climate change conversations is essential. The Waitangi Tribunal highlights areas where the Crown needs to work to improve Māori health outcomes. A clear deficit in existing policy process means a lack of preparedness for the intersecting health crises vulnerable Māori will experience in the face of climate change. Structural change is needed to strengthen health institution responsiveness to Māori health needs.
