title: Mechanical performance and fracture behavior of Fe₄₁Co₇Cr₁₅Mo₁₄Y₂C₁₅B₆ bulk metallic glass

authors: Chen, Qingjun

subjects: mechanical

abstract: The mechanical properties of a new Fe₄₁Co₇Cr₁₅Mo₁₄Y₂C₁₅B₆  bulk glassy alloy were studied by impact bending, compression, and hardness tests carried out at room temperature. The compressive fracture strength, elastic strain to fracture, Young’s modulus and Vickers hardness were measured to be 3.5 GPa, 1.5%, 265 GPa, and 1253 kg mm⁻², respectively. The fracture mode of the glassy alloy under uniaxial compression is different from those of other bulk metallic glasses in that this fracture mode causes the samples to be broken, in an exploding manner, into a large number of micrometer-scale pieces. The fracture mechanisms of this bulk glassy alloy under bending and uniaxial compression are discussed based on the observation of the fracture surfaces. Vickers indentation tests indicate that the structure of the glassy ingot may be inhomogeneous.

title: Regional and industry cycles in Australasia: Implications for a common currency

authors: Grimes, Arthur

subjects: common currency

abstract: If two countries experience similar cycles, loss in monetary sovereignty following currency union may not be severe. Analysis of cyclical similarity is frequently carried out at the overall industry level, then interpreted with reference to regional industrial structures. By contrast, this paper explicitly incorporates regional industry structure into an examination of Australasian cycles. Since 1991, NZ and Australasian cycles have been highly correlated, but there is little evidence that the NZ cycle has been “caused” by Australian regional or industry cycles. We test whether the NZDAUD exchange rate has insulated NZ from Australian shocks, but find it has not played a major buffering role in response to Australian industry shocks (including mining shocks). Instead, the strongest impacts on the NZDAUD stem from the NZ cycle. An important loss of monetary sovereignty under currency union may therefore arise in response to NZ-specific shocks.

title: "More than bloods and obs" - Whānau Māori discuss health and hospital care

authors: Masters-Awatere, Bridgette

abstract: The impact of colonisation on Māori, the Indigenous people of Aotearoa New Zealand, combined with negative interactions with health workers, has contributed to insufficient resources and reduced access to primary health care. The purpose of this report is to share narratives of whānau Māori who have experienced a child’s hospital admission in order to highlight the common aspects (good and bad) of their stay at Waikato Hospital. The overarching aim of the Harti Hauora Tamariki (HHT) tool trial, within which this report is located, is to demonstrate the measurable impact of a developed screening tool (referred to throughout as the Harti tool). The Harti tool is a comprehensive approach to assessing and addressing holistic health needs for hospitalised children and their whānau. Our recruitment strategy gave priority to those whose kōrero would capture the realities of those living in situations of few resources. This report presents findings from conversational interviews with whānau of tamariki Māori admitted to the paediatrics ward of Waikato Hospital. We have purposefully presented the interview findings as narratives to allow the reader to engage in their own interpretation of commonalities of experiences. Each case study follows the same format: an overview, their hospital experience, and their description of everyday health. Across all the cases, similarities of experience emerge; financial stressors and strain; hunger and isolation; concern for their child(ren); and families that are actively engaged in caring for their children’s health and well-being. The Harti tool, when administered by a culturally competent Harti Research Assistant (Harti RA), appears to work to counteract previous alienating experiences. Being treated with dignity, respect and value had a positive impact. Participants spoke at length regarding how wonderful it was to be able to engage with the Harti RA’s as Māori and in a culturally appropriate way.
