Passionate And Psychologically-Undetached: A Moderated-Mediated Investigation Of Psychological Distress Among Engaged Employees, Jennifer Ann L. Lajom, Stephen Teo, Moises Kirk De Carvalho Filho, Alicia Stanway

Research outputs 2022 to 2026

Guided by the effort-recovery model and the dualistic model of passion, we tested a conditional process model that examined the relationships between work engagement, workplace passion, psychological detachment, and psychological distress among Japanese professionals. We conducted an online panel survey across two time points, six weeks apart (N = 202 matched responses) where we measured all the variables at both instances. Findings show that engaged employees become susceptible to psychological distress due to decreased levels of psychological detachment. The moderating role of work passion was partially supported: being obsessively passionate towards work exacerbates this relationship further while contrary to expectations, …

Performing Feminist Research: Creative Tactics For Communicating Covid-19, Gender, And Higher Education Research, Jo Pollitt, Emily Gray, Mindy Blaise, Jacqueline Ullman, Emma Fishwick

Research outputs 2022 to 2026

Presenting research findings outside of the form of a traditional research report requires different modes of making and communicating. This paper offers an account of how The #FEAS Report, a satirical news video, was made to communicate the findings from interviews and a survey as part of the mixed-methods study, Sexism, Higher Education, and COVID-19: The Australian Perspective to a wider public. Three creative tactics for research communication were used: DIY aesthetics, humour, and situated bodies. These communication tactics enabled the researchers to think differently about what research findings mean, and how to articulate them in ways that are intelligible. …

Protective Indigenous Collective Value Of Ubuntu And Child Neglect: Implications For Rural Child Protection Practice, Alhassan Abdullah, Hajara Bentum, Margarita Frederico, Felix Mensah, Lucy P. Jordan, Clifton R. Emery

Research outputs 2022 to 2026

Theories on collective efficacy and social support suggest that indigenous values that support collective practices and sanction community obligations to childcare would be protective against child neglect. Likewise, new qualitative findings show that collective values are stronger in rural areas than in urban. This study tested the claims that the value of Ubuntu, which is a symbolic cultural value of ‘being for others’, will be protective against the likelihood of neglect; this relationship will be stronger in rural compared with urban communities in Ghana. Using data obtained from a nationally representative sample of 1100 mothers (from 22 communities) in Ghana, …

The Ability Of Ruppia Polycarpa To Regenerate From Seed Depends On Seasonal Porewater Salinity Dynamics And Declining Winter Rainfall Could Delay Recruitment, Chanelle L. Webster, Paul S. Lavery, Simone Strydom, Jessica Billinghurst, Kathryn Mcmahon

Research outputs 2022 to 2026

For many plants, regeneration from seed is vital for population recovery. Climate change is modifying the global hydrological cycle and a primary factor controlling germination of marine plants: salinity. How altered salinity regimes, and especially altered porewater salinity regimes, will regulate early life history stages of estuarine seagrasses is poorly understood. Here, we quantified the porewater salinity dynamics in two ephemeral estuaries that are dominated by the cosmopolitan genus Ruppia. Seedbank, germlings (germinated seeds) and seedlings were found in salinities ranging from 5 to 110 over an annual cycle. To understand the germination ecology of the dominant species, Ruppia polycarpa, …

The Negative Relationships Between Employee Resilience And Ambiguity, Complexity, And Inter-Agency Collaboration, Geoff Plimmer, Joana Kuntz, Evan Berman, Sanna Malinen, Katharina Näswall, Esme Franken

Research outputs 2022 to 2026

Employee resilience (ER) is often needed to face demands inherent in public sector work. Some types of demands, however, may hinder its development, rather than provide the type of challenging adversity from which resilience can develop. Public sector job demands have been a long-standing issue for public workplaces and employees but are also growing in salience as organisations face an increasingly variable, uncertain, complex, and ambiguous environment. Drawing on the Job Demands–Resources model and the challenge/hindrance stress literature, this multi-level study of Aotearoa New Zealand civil servants (n = 11,533) in 65 public sector organisations shows that ER is negatively …

Using Qpcr And Microscopy To Assess The Impact Of Harvesting And Weather Conditions On The Relationship Between Alternaria Alternata And Alternaria Spp. Spores In Rural And Urban Atmospheres, Godfrey Philliam Apangu, Carl Alexander Frisk, Beverley Adams-Groom, Geoffrey M. Petch, Mary Hanson, Carsten Ambelas Skjøth

Research outputs 2022 to 2026

Alternaria is a plant pathogen and human allergen. Alternaria alternata is one of the most abundant fungal spores in the air. The purpose of this study was to examine whether Alternaria spp. spore concentrations can be used to predict the abundance and spatio-temporal pattern of A. alternata spores in the air. This was investigated by testing the hypothesis that A. alternata dominates airborne Alternaria spp. spores and varies spatio-temporally. Secondarily, we aimed at investigating the relationship between airborne Alternaria spp. spores and the DNA profile of A. alternata spores between two proximate (~ 7 km apart) sites. These were examined …

The coated MnO₂ layers on FeO_x surface are responsible for decomposing H₂O₂ into O_{2 …}

Bioprospecting For And The Applications Of Halophilic Acidophiles In Bioleaching Operations, Melissa K. Corbett, Elizabeth L. J. Watkin

Research outputs 2022 to 2026

The economic recovery of metals from sulfide ores has become a topic of increasing interest due to the escalating demand for critical minerals and the reducing grade of available ores. Bioleaching is the use of acidophilic iron and sulfur-oxidising microorganisms to facilitate the extraction of base metals from primary sulfide ores and tailings. One significant issue limiting the use of bioleaching is the availability of freshwater due to the sensitivity of these microbes to chloride. The use of saline tolerant acidophilic iron- and-sulfur oxidising microorganisms will go a long way to addressing this issue. There are three possible means of …

“The Ice Is Melting And I Don’T Want Santa To Drown!”: Reflections On Childhood, Climate Action, And Futurity, Lucy Hopkins

Research outputs 2022 to 2026

This paper’s reading of a specific cultural artifact to emerge from children’s climate activism in contemporary Australia enacts an argument that children themselves can be seen to be redefining childhood and futurity through their climate activism and demonstrates how their placards are evidence of this. It argues that we as critical childhood scholars can follow their lead by uncovering the discourses that underpin their activist slogans. In doing so, we can set about contesting the limiting and disempowering discourses of childhood that would dismiss the very idea of children as political participants in the fight to save the planet.

The Influence Of Abiotic And Biotic Conditions On Lifecycle Stages Is Critical For Estuarine Seagrass Resilience, Chanelle Webster, Paul S. Lavery, Caitlyn O'Dea, Marta Sanchez Alarcon, Chandra Salgado Kent, Mcmahon

Research outputs 2022 to 2026

Abiotic and biotic factors influence seagrass resilience, but the strength and relative importance of the effects are rarely assessed over the complete lifecycle. This study examined the effects of abiotic (salinity, temperature, water depth) and biotic (grazing by black swans) factors on Ruppia spp. over the complete lifecycle. Structures were set up in two estuaries ( – 33.637020, 115.412608) that prevented and allowed natural swan grazing of the seagrasses in May 2019, before the start of the growing season. The density of life stage(s) was measured from June 2019 when germination commenced through to January 2020 when most of the …

Corrosion Behavior And Mechanisms Of The Heat-Treated Ti5cu Produced By Laser Powder Bed Fusion, Xin Wang, Peng Qin, L. Y. Chen, Hongqi Sun, Laichang Zhang

Research outputs 2022 to 2026

This work investigated the corrosion behavior of laser powder bed fusion produced (LPBFed) Ti5Cu and its heat-treated counterparts at 740 and 900 °C (named as HT-740 and HT-900 respectively) in Hank’s solution. The results indicated that the presence of acicular a'-Ti phase in LPBFed Ti5Cu was beneficial to corrosion, but the corrosion resistance of HT-740 and HT-900 were increased owing to the dual-phase microstructure (a'/a-Ti + Ti2Cu) or the increased content of Ti2Cu phase in the microstructure. The Ti2Cu phase could provide an ‘envelope’ protection to the a'/a-Ti phase and slow down the micro-galvanic reaction between a'/a-Ti phase and Ti2Cu …

Driving Training-Based Optimization (Dtbo) For Global Maximum Power Point Tracking For A Photovoltaic System Under Partial Shading Condition, Haroon Rehman, Injila Sajid, Adil Sarwar, Mohd Tariq, Farhad I. Bakhsh, Shafiq Ahmad, Haitham A. Mahmoud, Asma Aziz

Research outputs 2022 to 2026

The presence of bypass diodes in photovoltaic (PV) arrays can mitigate the negative effects of partial shading conditions (PSCs), which can cause multiple peak characteristics at the output. However, conventional maximum power point tracking (MPPT) methods can develop errors and detect the local maximum power point (LMPP) instead of the global maximum power point (GMPP) under certain circumstances. To address this issue, several artificial intelligence (AI)-based methods have been proposed, but they result in complicated and unreliable methodologies. This study introduces the driving training-based optimization (DTBO) method, which aims to address the partial shading (PS) problem quickly and reliably in …

Levels Of Autotrophy And Heterotrophy In Mesophotic Corals Near The End Photic Zone, Amy Carmignani, Veronica Z. Radice, Kathryn M. Mcmahon, Alex I. Holman, Karen Miller, Kliti Grice, Zoe Richards

Research outputs 2022 to 2026

Mesophotic corals live at ~30-150 m depth and can sustain metabolic processes under light-limited conditions by enhancing autotrophy through specialized photoadaptations or increasing heterotrophic nutrient acquisition. These acclimatory processes are often species-specific, however mesophotic ecosystems are largely unexplored and acclimation limits for most species are unknown. This study examined mesophotic coral ecosystems using a remotely operated vehicle (Ashmore Reef, Western Australia at 40 – 75m depth) to investigate the trophic ecology of five species of scleractinian coral (from genera Leptoseris, Pachyseris, and Craterastrea) using stable isotope analyses (δ13C and δ15N) of host and symbiont tissues and protein concentration. Trophic strategies …

Support For Climate-Driven Migration In Australia: Testing An Ideology-Based Threat Model, Samantha K. Stanley, Zoe Leviston, Caroline Ng Tseung-Wong

Research outputs 2022 to 2026

We examine Australians’ preferences for resettling people displaced by climate change from overseas (‘climate refugees’), from within Australia (‘internal climate refugees’), and people displaced by war. Across three studies (Study 1N = 467, Study 2N = 1679, Study 3N = 492), our findings reveal greater support for resettling refugee groups already residing in the nation: internal climate refugees and refugees of war. Although support for all three groups was reasonably high, participants were consistently and significantly less supportive of resettling international climate refugees. Both groups of international refugees (relocating due to war or climate changes) were viewed as posing greater …
