Shaping Youth Ministry: Exploring Influences On Youth Pastors’ Approaches To Programme Design, Timothy A. Mullen, Trudi Cooper

Research outputs 2022 to 2026

The literature on youth ministry practices is mostly anecdotal, and empirical research into the practices, goals, and meanings of youth ministry to youth pastors is rare, especially in Australia. In this study, 20 youth pastors in Perth, Western Australia, were interviewed about their goals, priorities, practices, training, and what influenced them. This study forms part of a larger doctoral research project. The interview data were analysed utilising a phenomenological approach, drawing upon Goffman’s framing analysis to examine the link between ‘meaning making’ and explicit and tacit motivations for youth ministry practice. The research found that youth pastors were most often …

Curing The Peasant's Disease : Frank Oldt’S Work And Research On Hookworm Disease In South China, 1905-1926, Jiaying Fu

Lingnan Theses (MPhil & PhD)

While current scholarship on “hygienic modernity” in China focuses on the construction of urban health systems and institutional infrastructures, this study proposes an alternative analytical lens by foregrounding the domain of agricultural health. It aims to investigate how early twentieth-century medical researchers uncovered public health models grounded in China’s agrarian conditions. Taking the case of Frank Oldt (1879–1976), a medical missionary living in Guangdong between 1905 and 1926, this research examines how he identified, interpreted, and sought to mitigate the problem of hookworm disease—a parasitic condition intricately linked to China’s farming practices and rural environmental conditions.

Specifically, this thesis aims …

School of Earth, Environmental, & Marine Sciences Faculty Publications

Soil ecosystem services, like the ability to store water, have been depleted after a century of conventional, annual cropping, and perennial crops offer a solution to this and other agricultural environmental issues. We assessed the impact of Miscanthus × giganteus (miscanthus), a perennial biomass crop, on soil water holding capacity and structure compared to continuous maize (Zea mays L.) at two sites in Iowa. After three growing seasons, we measured the following: (1) maximum water holding capacity (MWHC) with and without soil structure, and (2) total porosity and pore size distribution (PSD) via micro-computed tomography (microCT). Miscanthus increased MWHC …

The Document Divide: Public Record Requester Demographics, Efficacy And Those Left Behind, David Cuillier, A. Jay Wagner

College of Communication Faculty Research and Publications

Democratic theory suggests that people require accurate information, often via newspaper journalists, to make informed decisions and adequately self-govern. A survey of 330 U.S. public record requesters found that they skew heavily toward being White, male, non-Hispanic, educated, older, and affluent, compared with the U.S. population and the journalism community. Implications are discussed for journalism and society, particularly in light of newspaper layoffs and closures and heightened government secrecy.

Research outputs 2022 to 2026

Little evidence exists of whether decision-making in immersive 360° video is representative of the field setting in sport. The purpose of this study was to investigate whether decision-making performance of a representative exemplar competition specific skill was similar between 360° video and a field task. Fifteen players from skilled junior rugby union pathways and professional rugby union teams in Australia were recruited to complete a 360° video decision-making choice response task involving four attackers and three defenders. Their decision-making was previously assessed in a similar field decision-making task that was representative of rugby game play. Decision-making was scored according to …

Do Companies’ Green Credentials Enhance Trade Credit Provisions? Global Evidence, Rashid Zaman, Nader Atawnah, Deepa Banigidadmath, Muhammad Nadeem, Jia Liu

Research outputs 2022 to 2026

We investigate the impact of corporate renewable energy (RE) adoption on suppliers’ trade credit provisions. Using a global sample of 30 countries, we establish that firms engaging in higher RE consumption secure increased trade credit. Our results remain robust to a variety of sensitivity tests and after accounting for potential endogeneity concerns using the Paris Agreement and companies switching to green energy as exogenous shocks. Our channel analysis reveals that RE take-up mitigates companies’ environmental risk (proxied by environmental violation fines, media coverage of environmental controversies, GHG emissions, and environmental policy stringency). Additional tests reveal that the relationship between RE …

Moderate Coffee And Tea Consumption Is Associated With Slower Cognitive Decline, Stephanie R. Rainey-Smith, Kelsey R. Sewell, Belinda M. Brown, Hamid R. Sohrabi, Ralph N. Martins, Samantha L. Gardener

Research outputs 2022 to 2026

Background: Globally, coffee and tea are consumed extensively, potentially providing neuroprotection through anti-inflammatory and antioxidative stress effects. Objective: This study aimed to investigate associations between coffee and tea intake and cognitive function. Methods: In a longitudinal prospective cohort study, dementia-free (n = 8715; age range 60.0–85.2 years) older adults from the UK Biobank self-reported coffee and tea intake over the previous year; ‘never’, ‘moderate’ (1–3 cups/day), or ‘high’ (≥4 cups/day). Participants completed cognitive assessments at ≥2 timepoints (mean of 9.11 years). Results: Those ‘never’ consuming coffee and ‘moderate’ coffee consumers (β = 0.06, p = 0.005; β = 0.07, p <  0.001, respectively), as well as ‘moderate’ tea consumers and ‘high’ tea consumers (β = 0.06, p = 0.009; β = 0.06, p = 0.003, respectively) had slower fluid intelligence decline. Additionally, those ‘never’ consuming coffee and ‘moderate’ coffee consumers had a slower increase in pairs matching errors (β = −0.05, p = 0.022; β = 0.05, p = 0.013) compared to ‘high’ consumers. Conclusions: ‘Moderate’ coffee, and ‘moderate’ and ‘high’ tea intake may be a protective factor against cognitive decline. Randomized controlled trials are required to establish causal relationships leading to evidence-based recommendations regarding benefits of coffee and tea intake.

Research outputs 2022 to 2026

Complement-amplifying events/conditions associated with thrombotic microangiopathy (TMA) include pregnancy/postpartum period, severe hypertension, autoimmune diseases, drug exposures, infections and organ transplantation. Some of these ‘triggers’ may exist comorbidly with atypical haemolytic uraemic syndrome (aHUS; a complement-mediated form of TMA), unmask previously undiagnosed aHUS, or occur secondary to aHUS, thus creating a considerable diagnostic challenge. A major goal in patients presenting with TMA is to differentiate complement-mediated aHUS from other causes of TMA such that appropriate targeted treatment with complement 5 (C5) inhibitors can be initiated rapidly to avoid irreversible end-organ damage. To this end, nephrologists and haematologists from Australia, Hong Kong, …

Organization Research As An Applied Science: Lessons From Fields That Shape Practice And Policy, Stephen X. Zhang, Gokhan Ertug

Research Collection Lee Kong Chian School Of Business

As an applied science, our field aims to improve organizational effectiveness and solve practical problems (Hideg, DeCelles & Tihanyi, 2020; Pfeffer & Fong. 2002; Pillutla & Thau, 2013). However, despite the increasing sophistication in methods and greater emphasis on theory in recent decades, we have not made commensurate strides in relevance and impact. As we see it, the heart of this challenge is the culture in our field that demands novel theoretical advancement from every paper (Aguinis & Cronin, 2022), which may inadvertently constrain our ability to address pressing organizational challenges. Previous appeals to enhance our impact as an applied …

Esg News, Future Cash Flows, And Firm Value, Francois Derrien, Philipp Krüger, Augustin Landier, Tianhao Yao

Research Collection Lee Kong Chian School Of Business

We investigate the expected consequences of negative environmental, social, and governance (ESG) news on firms' future profits. After learning about negative ESG news, analysts significantly downgrade their forecasts at short and longer horizons. Negative ESG news affects forecasts more strongly at longer horizons than other types of negative corporate news. The negative revisions of earnings forecasts following negative ESG news largely reflect expectations of lower future sales, rather than higher future costs. Quantitatively, forecast revisions can explain most of the negative impacts of ESG news on firm value. Analysts are correct to revise forecasts downward following negative ESG news.
