title: The structure of the O₂-N₂O complex

authors: Salmon, Steven Ray

abstract: We have investigated the lowest energy structures and interaction energies of the oxygen nitrous oxide complex (O₂–N₂O) using explicitly correlated coupled cluster theory. We find that the intermolecular potential energy surface of O₂–N₂O is very flat, with two minima of comparable energy separated by a low energy first order saddle point. Our results are able to conclusively distinguish between the two sets of experimental geometric parameters for O₂–N₂O that were previously determined from rotationally resolved infrared spectra. The global minimum structure of O₂–N₂O is therefore found to be planar with a distorted slipped parallel structure. Finally, we show that the very flat potential energy surface of O₂–N₂O is problematic when evaluating vibrational frequencies with a numerical Hessian and that consideration should be given as to whether results might change if the step-size is varied.

title: Exclusion and inaction: Academic precariat experiences of union representation in Aotearoa New Zealand

authors: Salter, Leon

abstract: During the last 40 years, neoliberal reforms to the tertiary sector have led to the casualisation of academic labour and the emergence of an academic precariat in Aotearoa New Zealand. Despite the increasing size of the academic precariat, it does not appear that their voices, concerns, or interests have been adequately represented by the national tertiary union. By drawing on open-text responses from the Precarious Academic Work Survey (PAWS) about what unions could do to improve precarious academic working conditions, we discuss the issues created by the under-representation of precarious academics by the sector union. We communicate the results via four key themes of exclusion, participation, voice, and organising. Most participants articulated frustration and disaffection with the union, suggesting the need for a shift in strategy. This study adds to the growing body of employment relations research recognising that employee voices are multiple, diverse, and fragmented; indicating that unions must attend to the differential experiences of people working in the tertiary sector attributable to employment practices.

title: Ha ora: Improving access to early diagnosis of lung cancer for Maori and rural communities. Understanding patient experiences in General Practice

authors: Lawrenson, Ross

abstract: There were two main objectives for this report. The first was to identify the barriers to early diagnosis of lung cancer experienced by Māori lung cancer patients and whānau. Second was to co-design a multi-pronged intervention alongside rural Māori communities to improve early diagnosis of lung cancer for whānau in their localities.
The team worked in the Waikato, Lakes, Bay of Plenty and Tairāwhiti districts of the Midland Region. Semi-structured interviews were carried out with 23 Māori lung cancer patients and whānau recruited through respiratory or cancer nurse specialists (CNSs) based at the hospitals of each district. Nine community hui (focus groups) and nine primary healthcare provider hui were carried out in five rural localities: Te Kuiti, Opōtiki, Te Kaha, Rotorua and Gisborne. Community hui included cancer patients, whānau, and other community members. Healthcare provider hui comprised staff members at the local primary healthcare centre, including General Practitioners and nurses. Study data were thematically analysed.
Findings of the study highlight:
1. Barriers in primary care, including symptom ambiguity, accumulating costs, barriers and enablers relating to GP – patient relationships
2. Barriers in secondary care, including a lack of access to diagnostic tests, long waiting times, barriers and enablers relating to communication between HCPs and patients.
3. The importance of whānau as carers and advocates for Māori patients on their lung cancer journey.
The interventions co-designed with each community included a Hā Ora website, a series of lung cancer awareness videos (entitled ‘wharo wharo wharo’), a kaiawhina training programme and a ‘pou pupuru oranga’ (cancer navigator).
We suggest strategies that aim to improve early diagnosis of lung cancer for rural Māori communities. We welcome your feedback to us regarding these recommendations.
