title: Providing space for indigenous knowledge

authors: Tangihaere, Tracey Mininoa

subjects: indigenous knowledge

abstract: Colonial influences have generally failed to respect indigenous knowledge, languages, and cultures. Determination to reclaim First Nations identity is visible in many jurisdictions. First Nations Peoples continue to call on governments to facilitate changes needed to revitalize their economic, social, cultural, and spiritual well-being. This article is a reflective article generated from our response to the situation of Mäori, the indigenous peoples of New Zealand. It provides a background on the historical attempts to weaken Mäori leadership and the resilience of Mäori in their resistance to such undermining. Using a description of a physical space, the Marae (the meetinghouse), the authors provide a glimpse into a distinctive Mäori psychology connected to Marae encounters and into Mäori ways of thinking, feeling, and behaving. Three examples of organizational practice at the incorporation of such values are provided. Four implications for management education are posited as relevant not only to the education of managers in Aotearoa but wherever engagement with indigenous people occurs.

title: Experiences of New Zealand Māori mothers’ Engagement with health and social services post-COVID-19 2020 lockdown

authors: Barrett, Nikki Maree

subjects: Childbirth

abstract: Background: 
Despite universal provision of maternity care, Māori (Indigenous peoples of Aotearoa/New Zealand) experience significant maternal and infant health disparities compared to their dominant Pākehā (non-Māori) counterparts. This paper examined the lived realities of postnatal Māori māmā (mothers) engaging with health and social services. Enablers and barriers were identified to better understand what is required to strengthen health services’ responsiveness to Māori māmā health needs and aspirations. 

Methods: 
Underpinned by Kaupapa Māori research principles, which are grounded in Māori cultural values, emphasising self-determination, and Māori aspirations, a small cohort of 17 expectant Māori māmā were recruited from a Māori childbirth education programme to participate in a three-phase study. Phase three, the focus of this paper, involved seven semi-structured, open-ended telephone interviews with Māori māmā. A thematic analysis, underpinned by a mana wahine (authority inherent in Māori women) theoretical perspective amplified these experiences. 

Results: 
Five themes were identified that encapsulated participants’ engagement and interactions with health and social services. These themes were as follows: (1) right to enact tino rangatiratanga (autonomy) and self-achievement; (2) responsiveness of services; (3) service and system issues; (4) need for greater choice and opportunity; and (5) impact of COVID-19. 

Conclusions: 
This study privileged the voices of Māori wāhine, highlighting their experiences with a complex and often unresponsive health system. Participants valued services that enabled them to exercise tino rangatiratanga. Echoing the experiences of other Indigenous Peoples, incorporating culturally relevant practices into perinatal health services is crucial for achieving health equity and addressing disparities.

title: Numerical performance comparison of different tube cross-sections for heat recovery from particle-laden exhaust gas streams

authors: Walmsley, Timothy Gordon

abstract: Heat recovery from exhaust gas streams is applicable to a wide variety of industries. However, high heat transfer resistance of gases and the presence of entrained particulate matter that readily fouls limits industry uptake of current heat recovery technology. Improvements to standard heat exchanger designs are needed. In this study Computational Fluid Dynamics (CFD) is used to investigate the effect of ten different tube cross-sections on heat transfer resistance, gas flow resistance and foulability. The average wall shear stress around the shape is used to predict foulability and an estimated asymptotic fouling resistance is used to calculate an equivalent fouled Coulburn j factor, jf. CFD results show the best tube for exhaust heat recovery is an elliptical tube closely followed by the flattened round tube. The ellipse shape produced fouled Coulburn j factor, jf values, expressed as a ratio of tube bank friction factor f, over 100% higher than that of standard round tube. A flattened round tube is also promising, given enough spacing between the tubes, and may be the practical economic optimum.
