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.

Management Of Atypical Haemolytic Uraemic Syndrome With Triggers: Diagnostic And Treatment Algorithms From An Asia-Pacific Perspective, Hee Gyung Kang, Danny Hsu, Noritoshi Kato, Jin Seok Kim, Masayoshi Okumi, Min Hua Tseng, Kun Hua Tu, Desmond Yat Hin Yap, Wai H. Lim

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.

From The Great Recession To The Post-Covid 19 Pandemic U.S. Municipal Fiscal Condition: “Austerity Urbanism,” “Pragmatic Municipalism” And On-Going Explanatory Challenges, Mark Davidson, Kevin Ward

Geography

How much did the Great Recession change U.S. municipal budgetary and fiscal governance? According to an academic literature that subsequently emerged, the period saw a combination of both change and continuity. The work offered two distinct ways to explain and understand the emerging context: austerity urbanism and pragmatic municipalism. This paper reviews these explanations with the goal of showing how and why they developed contrasting conceptualizations. We argue differing epistemological approaches underpin the two competing approaches. Understanding these differences is, we argue, critical for moving forward. The COVID 19 pandemic saw another round of changes to U.S. municipal budgetary and …

Christian Character Formation In A Culture Of Anger, Rebecca Konyndyk Deyoung

University Faculty Publications and Creative Works

Anger is a hot topic, perhaps especially for Christians. We might concede that it’s OK to be angry sometimes—for example, when human rights are violated. It’s not right to be complacent or indifferent in the face of that kind of intentional injury! At the same time, we might be wary of justifying anger, given how many times we’ve been harmed—or seen others harmed— by people who get too angry. No one who has encountered Christians ranting on social media thinks we need more of that kind of witness.

Patterns And Implications Of Missed Injuries On Computed Tomography Imaging In Older Blunt Trauma Patients, Arnav Mahajan, Vanessa P. Ho

Faculty Scholarship

Background: Older adults sustain disproportionately morbid injuries from low energy mechanisms, yet guidance around computed tomography imaging is lacking for this demographic. We hypothesize that current imaging practices may lead to potentially missed injuries, increasing morbidity and mortality. Methods: A secondary analysis of a prospective multicenter study (11/2020–12/2021) of older blunt trauma patients was performed. Suboptimal imaging was defined as a mismatch between final injury diagnosis and initial computed tomography imaging. We compared optimally vs not optimally imaged patients to determine factors associated with suboptimal imaging and examined mortality, hospital length of stay, and critical care use with a multivariable …

Retinoid Dynamics In Vision: From Visual Cycle Biology To Retina Disease Treatments, Jaclyn Swigris, Made Airanthi K. Widjaja-Adhi, Marcin Golczak

Faculty Scholarship

Light perception is a biological process that facilitates a profound interaction between the external world and the internal functions of living organisms. It begins with the absorption of photons with specialized visual pigments that contain vitamin A-derived chromophores. The light energy triggers the photoisomerization of the visual chromophore, initiating a cascade of signaling events that ultimately convert light into electrical signals interpreted as vision. However, the sustainability of vision relies on the continuous supply of the visual chromophore, which is maintained through light-dependent and light-independent processes. The importance of these processes is underscored by numerous blinding retinal diseases linked to …
