Trump’S Multi-Pronged Attack On Renewable Energy, Michael B. Gerrard

Faculty Scholarship

Federal policy on renewable energy took a 180-degree turn on the day of Donald Trump’s second inauguration. The Biden administration had rightly seen a massive expansion of clean energy, especially wind and solar and the associated storage and transmission, as key to moving away from fossil fuels and fighting climate change. But Mr. Trump denies that climate change is a serious problem and works to increase both the supply of and the demand for fossil fuels.

This article discusses the range of actions involved in the Trump administration’s attack on renewable energy.

Systemic Racism In Canadian Healthcare: A Policy And Equity Analysis, Kola Adegoke, Abimbola Adegoke, Deborah Dawodu, Temitope Kayode

Health & Biomedical Sciences Faculty Publications

The Role Of Fungal Proteases In Bioactive Peptide Production And Analytical Approaches For Tracking Their Activity, Tanvir Ahmed, Angéla Juhász, Utpal Bose, Netsane Shiferaw Terefe, Michelle L. Colgrave

Research outputs 2022 to 2026

Fungal proteases catalyse site-specific peptide bond cleavage in complex protein matrices, enabling bioactive peptide (BP) release. Accurate monitoring is vital for optimising hydrolysis efficiency, minimising nonspecific proteolysis, ensuring consistent yields, and preserving peptide biofunctionality. While analytical and computational tools are well-established for non-fungal systems, their adaptation to fungal proteases remains exploratory, with no comprehensive evaluation addressing the unique challenges in this field. This review synthesises current knowledge, identifies methodological gaps, and outlines future directions for developing fungi-specific analytical pipelines and computational frameworks for BP discovery. It explores fungal protease families, their roles in intracellular peptide processing, and fungal survival strategies. …

Technology Discontinuance: A Systematic Literature Review And Research Agenda, Birgit Altrichter, Sabine Benoit

Research Collection Lee Kong Chian School Of Business

Technology discontinuance by users who quit digital services such as social media or lose interest in their devices after a few weeks is a common phenomenon. Yet it has received little research attention; the few studies that address it are scattered across disciplines. Research into customer churn is more prevalent, but it implies switching providers rather than halting usage altogether. By moving beyond discipline-based knowledge boundaries and conducting a systematic literature review, the current article proposes a technology discontinuance framework, which details seven technology discontinuance types (overuse, overload, proficiency, disenchantment, social, circumstantial, and solution) and their drivers. For example, guilt …

Managing The Personalization Paradox: Lessons From Spotify’S Ai Dj, Anirban Mukherjee, Hannah H. Chang, Jonathan Wibowo

Research Collection Lee Kong Chian School Of Business

This case study uses Spotify’s AI DJ to examine the “personalization paradox,” where product features designed to deepen user connection can instead cause alienation. An analysis of over 1,400 user comments identifies three core frictions: a perceived loss of user agency, mismanaged expectations for the human-like AI, and a scalability bottleneck that led to repetitive content. Students are placed in the role of a product manager tasked with developing a prioritized roadmap to address these issues, forcing them to grapple with the critical trade-offs between technological capability and user psychology.

Determining The Accumulation Potential Of Nanoplastics In Crops: An Investigation Of 14C-Labelled Polystyrene Nanoplastic Into Radishes, Nathaniel J. Clark, Astrid C. Fischer, Demelza Carne, George R. Littlejohn, Lee J. Durndell, Anne Plessis, Richard C. Thompson

School of Biological and Marine Sciences

The capacity of crops to accumulate nanoplastics has remained relatively unexplored largely due to analytical constraints. To address this challenge, the present study employed a radiolabelling approach to demonstrate, for the first time, that polystyrene nanoplastics (¹⁴C-PS NPs) accumulate and move into the edible tissues of radishes (Raphanus sativus). Radishes were exposed hydroponically for five days, with only their non-fleshy roots in contact with the ¹⁴C-PS NPs, while accumulation in the fleshy (edible) roots and shoots was subsequently measured. The radish roots retained nearly 5 % of the ¹⁴C-PS NPs from the exposure, either through accumulation …

Plastic Or Natural? The Impact Of Marine Debris On The Shell Preference Of A Terrestrial Hermit Crab, Robert Puschendorf, Pete Cotton, Mark Briffa

School of Biological and Marine Sciences

Plastic pollution is one of the main human-induced rapid environmental changes threatening marine organisms. Terrestrial hermit crabs, which inhabit coastal areas where litter accumulates, are increasingly documented using plastic debris as shells, and a recent study hypothesized that this shift may be an adaptive response. They suggested that ‘plastic shells’ may reduce transport costs, provide camouflage in a polluted environment, and may even be favoured by sexual selection. Our study is the first to quantify plastic shell use in a population, to examine shell preference and to test the hypothesis that plastic shells optimize the ratio of weight to volume. …

Characterizing Piezoelectric-Blended Polydimethylsiloxane For Use As A Mechanoelectrical Responsive Cell Culture Substrate, Alexis P. Applequist, Lance D. Cordes, Lais A. Ferreira, Kartik Balachandran

Biomedical Engineering Faculty Publications and Presentations

In this study, we developed a piezoelectric-polydimethylsiloxane (pz-PDMS) composite by blending poly(vinylidene fluoride-co-trifluoroethylene) (P(VDF-TrFE)) with PDMS to create a biocompatible, mechanoelectrical responsive material. The pz-PDMS was synthesized with varying piezoelectric concentrations (0%, 1%, 3%, and 5%) and characterized for visual properties, mechanical properties, mechanoelectrical sensitivity, and biocompatibility. Compression testing showed no significant change in mechanical strength with the addition of piezoelectric particles, while mechanolectrical sensitivity testing revealed a non-linear increase in voltage response, with 5% pz-PDMS producing the highest sensitivity. Fatigue testing demonstrated no change in sensitivity after 7 days of cyclic displacement. Additionally, microcantilever experiments demonstrated the high fidelity …

Foreign Director Exit In The Midst Of Deteriorating Bilateral Political Relations, Xiaocong Tian, Yuehua Xu, Daphne W. Yiu

Research Collection Lee Kong Chian School Of Business

Amid global geopolitical realism pushing for a race of hegemonic rivalry nowadays, an outflow of global human talents is a pressing organizational concern. Our study draws attention to the underexamined phenomenon of the exit of foreign directors from their host countries during geopolitical tensions. Theorizing from a sensemaking logic, we posit that the deterioration of bilateral political relations serves as an unexpected event that activates foreign directors’ schemas for dual identity conflict, propelling them to react behaviorally to such identity threats by exiting the board in the host country. In addition, we further posit that the sensemaking process is contingent …

Providing Spatial Support During A Major Cholera Outbreak In Port-Au-Prince, Haiti: Creative Mapping Solutions In A Challenging Data Poor Environment, Andrew Curtis, Jayakrishnan Ajayakumar

Faculty Scholarship

In this paper we describe the spatial data challenges faced in terms of providing accurate and timely analysis for a clinic during a cholera epidemic that spread through Port au Prince, Haiti in late 2022. This “triage” spatial epidemiology involved developing a bespoke geocoder that allowed for weekly maps of spread to be created in near real time. Resulting case data were also analyzed using a novel grid heatmapping approach which considers the epidemiological curve for each neighborhood. Adding further complexity during this period to both the data generation, and explaining cholera amplification and spread patterns, was a rising gang …

Home And Religion, Emma Alexandra Grimley, Orlando Woods, Lily Kong

Research Collection College of Integrative Studies

This chapter explores how religious practices and identities intersect with the home as both a construct and physical locale and surveys the social science literature on religion in/and the home. We argue that the shifting space-times of religious practice reflect and influence the changeable and porous boundaries between public and private space, the home and beyond the home. This influence is shown by reference to three areas of focus: the home as a private space of and for religion; the use of religion to cross social and spatial boundaries of home; and the reconfiguration of the home in religious practice …

The purpose of this study was to explore the effect of perceived principal leadership styles and school type on elementary teachers’ self-efficacy. The study examined two research questions. The first examined differences between teachers’ self-efficacy in Title 1 and non-Title 1 schools, and the second examined differences in teacher self-efficacy and perceived principal leadership styles (authoritarian, democratic, and laissez-faire). The convenience sample included 129 elementary teachers from social media teacher groups that taught in various Title 1 and non-Title 1 school districts. I used a quantitative, causal-comparative method to collect data and survey questionnaires that identified trends in leadership styles …

From Personas To Talks: Revisiting The Impact Of Personas On Llm-Synthesized Emotional Support Conversations, Shenghan Wu, Yimo Zhu, Wynne Hsu, Mong-Li Lee, Yang Deng

Research Collection School Of Computing and Information Systems

The rapid advancement of Large Language Models (LLMs) has revolutionized the generation of emotional support conversations (ESC), offering scalable solutions with reduced costs and enhanced data privacy. This paper explores the role of personas in the creation of ESC by LLMs. Our research utilizes established psychological frameworks to measure and infuse persona traits into LLMs, which then generate dialogues in the emotional support scenario. We conduct extensive evaluations to understand the stability of persona traits in dialogues, examining shifts in traits post-generation and their impact on dialogue quality and strategy distribution. Experimental results reveal several notable findings: 1) LLMs can …

Crisis Observatory: Extracting Credible Signals During A Crisis In The Age Of Llms, Kuan-Chieh Lo, Pranav Maneriker, Sriram Sai Ganesh, Dominik Winecki, Kelly Garrett, Ayaz Hyder, Arnab Nandi, Valerie Shalin, Shannon A. Bowen Ph.D., Amit Sheth, Srinivasan Parthasarathy

Publications

Systems for crisis response have required several different models for the analysis of unstructured text, such as identifying needs, locations, topics, routing, and matching of needs with available responders. Large Language Models (LLMs) have replaced task-specific models across various language processing tasks. However, LLMs are known to be limited by their training data, collected before the crisis. In this demo, we explore the use of LLMs for crisis response scenarios with rapidly evolving information environments. We show how the augmentation of these models with external reliable sources of crisis-specific information can help build adaptive systems for response. The demonstration video …

Swiping Rights: Hidden Costs Of Hidden Laws, Rachel Landy

Articles

While many legal regimes have undergone fundamental shifts to account for the online economy, one lags behind: industry-specific mandatory contract rules. These rules, frequently buried in decades-old, nonintuitive statutes, are often overly prescriptive and come with draconian penalties, hampering the goals of entrepreneurship and impeding startup growth.

Much has been written about the intersection of regulation and entrepreneurship. But sparse attention has been paid to the unintended consequences on early-stage companies of more subtle regulatory interventions like contract rules — especially those with inconsistent or conflicting requirements among the states. This Article begins to fill that gap and uses as …

The Irrelevance Of “Peak Fame” On Celebrity Candidate Success, Richard T. Longoria, Dana Reyes

Political Science Faculty Publications

Objective

Does it matter “when” a celebrity runs for office? The political scientists who study celebrity candidates need to consider an important insight from communications and media scholars. Fame is a time-dependent variable. Someone who was famous 40 years ago may no longer be widely known today.

Methods

A list of celebrity political candidates who ran for office in the United States between 1865 and 2022 was created to measure campaign success.

Results

In terms of winning an election, it does not matter whether a celebrity candidate runs at the peak of their fame or waits until decades later. What …

Caskey, Robert Chen, Ghazaleh Darmani, Ellen J. Bubrick, Jérôme Sallet, Christopher R. Butler, Charlotte J. Stagg, Miriam C. Klein-Flügge, Seung Schik Yoo, Christy K. Holland, Bradley Treeby, Eleanor Martin, Lennart Verhagen, Kim Butts Pauly

School of Psychology

Transcranial ultrasound stimulation (TUS) is an emerging technology for non-invasive brain stimulation. The International Transcranial Ultrasonic Stimulation Safety and Standards consortium (ITRUSST) has established consensus on considerations for nonsignificant biophysical risk of TUS, drawing upon the literature and established regulations for biomedical devices. Here, we assume the application of TUS to individuals without contraindications, compromised thermoregulation, vascular vulnerabilities, or administered ultrasound contrast agents. In this context, we present a concise yet comprehensive set of levels for nonsignificant risks of TUS application. For mechanical effects, it is non-significant risk if the mechanical index (MI) or the mechanical index for transcranial application …

Discussion Of "Csr And Negative Corporate Events: The Moderating Role Of Managerial Overconfidence", Hye Sun Chang

Research Collection School Of Accountancy

Corporate social responsibility (CSR) refers to the notion that firms are accountable not only to shareholders but also to a broader set of stakeholders including customers, employees, creditors, and the communities in which they operate. Although CSR has long been part of corporate discourse, its prominence has grown with the rise of environmental, social, and governance (ESG) concerns. Today’s consumers and stakeholders are increasingly attentive to issues such as climate change, economic inequality, labor rights, and social justice, prompting firms to align their strategies with evolving societal expectations. Building on this increasingly salient backdrop, Chu et al. (2026), hereafter CCT, …
