Market Reactions To Deceptive Language In Fake News: Implications From Language Expectancy Theory And Transfer Learning, Ka Chung Ng, Ping Fan Ke, Ping Fan, Mike So, Tam, Kar Yan May 2026

Market Reactions To Deceptive Language In Fake News: Implications From Language Expectancy Theory And Transfer Learning, Ka Chung Ng, Ping Fan Ke, Ping Fan, Mike So, Tam, Kar Yan

Research Collection School Of Computing and Information Systems

The advent of generative artificial intelligence (AI) has heightened the proliferation of fake news. A key challenge is the limited real-world data to investigate the societal impact of fake news produced by generative AI. In this paper, we examine stock market reactions to financial news articles that exhibit stylometric similarity to human-crafted and AI-crafted fake financial news. Grounded in language expectancy theory, we employ a style-based transfer learning model, pre-trained to recognizing deceptive language employed in various types of fake news intricacies. We then apply this model to a comprehensive dataset of financial news, assigning a “veracity style score” to …

Fighting Against Recruitment Scams: Theory-Driven Supervised Learning And Empirical Analysis For Digital Fraudulent Recruitment Posting Behavior, Tom (Tianteng) Wang, David (Jingjun) Xu, Keng Siau, Zhongju (John) Zhang May 2026

Fighting Against Recruitment Scams: Theory-Driven Supervised Learning And Empirical Analysis For Digital Fraudulent Recruitment Posting Behavior, Tom (Tianteng) Wang, David (Jingjun) Xu, Keng Siau, Zhongju (John) Zhang

Research Collection School Of Computing and Information Systems

The number of recruitment postings on digital recruitment hiring platforms has increased since the COVID-19 pandemic. However, the weak surveillance and operations of these platforms, combined with the fact that most job seekers have relatively low vigilance and a strong desire for recruitment offers, enable scammers to easily deceive job seekers for their money and confidential information. In this work, we combine prevailing text mining techniques (i.e., ChatGPT with prompting engineering and supervised machine learning) with interpersonal deception theory (IDT) from social science to design an interpretable IT system to predict fraudulent recruitment postings on digital recruitment-hiring platforms. We compare …

Understanding Critical Thinking In Generative Artificial Intelligence Use: Development, Validation, And Correlates Of The Critical Thinking In Ai Use Scale, Gabriel R. Lau, Wei Yan Low, Louis Tay, Ysabel Thereze Ang Guevarra, Dragon Gašević, Andree Hartanto May 2026

Understanding Critical Thinking In Generative Artificial Intelligence Use: Development, Validation, And Correlates Of The Critical Thinking In Ai Use Scale, Gabriel R. Lau, Wei Yan Low, Louis Tay, Ysabel Thereze Ang Guevarra, Dragon Gašević, Andree Hartanto

Research Collection School of Social Sciences

Generative AI tools are increasingly embedded in everyday work and learning, yet their fluency, opacity, and propensity to hallucinate mean that users must critically evaluate AI outputs rather than accept them at face value. The present research conceptualises critical thinking in AI use as a dispositional tendency to verify the source and content of AI-generated information, to understand how models work and where they fail, and to reflect on the broader implications of relying on AI. Across six studies ( N = 1341), we developed and validated the 13-item critical thinking in AI use scale and mapped its nomological network. …

Leading Ai Adoption In Organizations: Introducing A Behavioral Human-Centered Approach, Shane Schweitzer, Devesh Narayan, Jack Mcguire, David De Cremer May 2026

Leading Ai Adoption In Organizations: Introducing A Behavioral Human-Centered Approach, Shane Schweitzer, Devesh Narayan, Jack Mcguire, David De Cremer

Research Collection Lee Kong Chian School Of Business

Initiatives to implement AI technologies in organizations fail at an alarming rate. We argue that leading the adoption of AI is not a simple engineering exercise but rather represents a behavioral exercise where change management principles—the process by which organizations plan, implement, and embed changes in practices—are employed. However, many AI initiatives in business focus predominantly on the AI systems themselves, assuming humans will fall in line. To solve this, we integrate ideas from change management with scholarship on human-centered artificial intelligence to offer a behavioral approach that accounts for the impact of AI adoption on humans at all stages …

Gencode: A Generic Data Augmentation Framework For Boosting Deep Learning-Based Code Understanding, Zeming Dong, Qiang Hu, Xiaofei Xie, Maxime Cordy, Mike Papadakis, Yves Le Traon, Jianjun Zhao

Research Collection School Of Computing and Information Systems

Pre-trained code models lead the era of code intelligence, with multiple models designed with impressive performance. However, one important problem, data augmentation for code data that automatically helps developers prepare training data lacks study in this field. In this paper, we introduce a generic data augmentation framework, GenCode, to enhance the training of code understanding models. Simply speaking, GenCode follows a generation-and-selection paradigm to prepare useful training code data. Specifically, it employs code augmentation techniques to generate new code candidates first and then identifies important ones as the training data by influence scores. To evaluate the effectiveness of GenCode, we …

International Business And Sustainability: Towards An Interdisciplinary Research Agenda, Jonathan Doh, Ans Kolk, Heli Wang May 2026

International Business And Sustainability: Towards An Interdisciplinary Research Agenda, Jonathan Doh, Ans Kolk, Heli Wang

Research Collection Lee Kong Chian School Of Business

The relationship between international business (IB) and sustainability is a complex and multifaceted one. Multinational enterprises (MNEs) both affect and are affected by the social, economic, and ecological (green environment) context in which they are embedded.1 As such, the study of how IB activity influences sustainability and the way that sustainability, in turn, impacts IB, involves incorporating a wide range of drivers, actors, processes, and outcomes. At the same time, sustainability challenges, such as climate change, biodiversity loss, pollution, resource scarcity, economic and social inequality and others, are increasingly systemic, multilevel, and intertwined with geo economic, biophysical and governance dynamics …

Causality-Driven Test Case Minimisation For Cyber-Physical Systems, Michael Foster, Christopher M. Poskitt, Nicholas R. Latimer, Neil Walkinshaw, Richard Somers, Robert M. Hierons May 2026

Causality-Driven Test Case Minimisation For Cyber-Physical Systems, Michael Foster, Christopher M. Poskitt, Nicholas R. Latimer, Neil Walkinshaw, Richard Somers, Robert M. Hierons

Research Collection School Of Computing and Information Systems

Cyber-physical systems allow digital control systems to interact with the physical world using sensors and actuators. They are increasingly being used to automate critical infrastructure, where software faults can have dire consequences. Due to the complex nature and unpredictability of these systems, their resilience is often tested using a technique called fuzzing, which generates quasi-random sequences of sensor and actuator manipulations with the goal of forcing a system into unsafe states. However, there is currently no way of determining which manipulations of a test case cause a failure without systematically removing each one and re-running the test, which can be …

Func: Reducing The Impact Of Android Framework Evolution On Malware Detection, Hailong Yu, Tiantian Wang, Lwin Khin Shar, Hanmeng Li, David Lo May 2026

Func: Reducing The Impact Of Android Framework Evolution On Malware Detection, Hailong Yu, Tiantian Wang, Lwin Khin Shar, Hanmeng Li, David Lo

Research Collection School Of Computing and Information Systems

Android malware detection approaches commonly use APIs and permissions as features for classifying malware. However, since the release of the first Android operating system in 2008, the Android framework has undergone numerous version updates. The evolution of the Android framework over time has led to changes in APIs and permissions, including deprecations and replacements. These changes can result in inaccurate characterization of Android malware, thereby affecting performance of malware detectors. There is a lack of methods to mitigate the impact of Android framework evolution on malware detection. To fill this gap, we conduct a systematic study of the impact of …

The Effect Of A 14-Day Digital Nudge-Based Sleep Hygiene Intervention On Behavioural, Cognitive, And Emotional Well-Being In College Students: An Experimental Approach, Tracy X. Chen, Chi-Ying Cheng, Michelle Koay, Chin Boon Soh, Andree Hartanto May 2026

The Effect Of A 14-Day Digital Nudge-Based Sleep Hygiene Intervention On Behavioural, Cognitive, And Emotional Well-Being In College Students: An Experimental Approach, Tracy X. Chen, Chi-Ying Cheng, Michelle Koay, Chin Boon Soh, Andree Hartanto

Research Collection School of Social Sciences

Sleep is essential for one's cognitive, psychological, and physical health. Yet, college students often face sleep deprivation due to academic demands, social obligations, and extracurricular commitments. This study implemented a 14-day Digital Nudge-Based Sleep Hygiene Intervention, delivered via a digital platform, to encourage healthier sleep practices among college students. Grounded in nudge theory, the digital intervention used subtle behavioural prompts to improve participants' sleep hygiene without imposing restrictions, demonstrating high adherence and scalability. Participants were guided through daily tasks to enhance autonomy and motivation, such as creating calming bedtime routines. The digital intervention led to positive outcomes across four domains: …

Outcomes Associated With Childhood Parental Divorce: An Umbrella Review Of Meta-Analyses, Gabriel Xing Da Tan, Andree Hartanto, Ysabel Thereze Ang Guevarra, Angel K. M. P. Lee, Jing Jie Kenneth Koh, K Tennakoon Appuhamillage Sandeeshwara Kasturiratna May 2026

Outcomes Associated With Childhood Parental Divorce: An Umbrella Review Of Meta-Analyses, Gabriel Xing Da Tan, Andree Hartanto, Ysabel Thereze Ang Guevarra, Angel K. M. P. Lee, Jing Jie Kenneth Koh, K Tennakoon Appuhamillage Sandeeshwara Kasturiratna

Research Collection School of Social Sciences

Background: Childhood parental divorce has been consistently associated with a host of negative outcomes across multiple domains, such as socioemotional, behavioural, academic, and physical health, which can persist into adulthood. Despite extensive research on childhood parental divorce, the current literature lacks a systematic, integrated synthesis that clarifies which child outcomes are most consistently associated with parental divorce, as well as the potential moderators influencing these associations. Therefore, we conducted an umbrella review of meta-analyses to bridge this gap by consolidating the existing research and providing an exhaustive overview. Methods: Systematic searches were conducted across various databases and following a two-stage …

The Smallholder’S Dilemma In Agroecological Transitions: The Diseconomy Of Agroecology For Small Farmers In Industrial Agriculture, Qian Forrest Zhang May 2026

The Smallholder’S Dilemma In Agroecological Transitions: The Diseconomy Of Agroecology For Small Farmers In Industrial Agriculture, Qian Forrest Zhang

Research Collection School of Social Sciences

A scalar contradiction exists between agroecology's three goals: while ecological sustainability is best pursued at the landscape scale, social equity and livelihood goals often require organizing production at the small scale of family farms. In China's ‘industrial agriculture of small farmers’, ecological farming practices became economically unviable at small farmers' minuscule scales. Agroecological transitions almost always first go through a scale expansion, a process fraught with tension. The empirical analysis focuses on three ‘ecological farms’ that enjoyed favorable conditions unattainable to smallholders. Yet, lock-ins across five dimensions have either made their operations economically unsustainable or forced compromises in agroecological principles.

Log Off To Level Up: The Effect Of Social Media Hiatus On Goal Pursuit, Nekysha L. Y. Jalil, Yong Han Tan, Andree Hartanto, Eddie M. W. Tong

Research Collection School of Social Sciences

Concerns are growing that social media, with its constant notifications and attention-grabbing content, may distract individuals and hinder progress toward important goals. Despite its pervasive presence in our lives, the impact of social media on goal achievement has not been thoroughly studied. This within-subject experimental study aims to investigate the effects of social media hiatus (SMH), a short abstinence from social media usage, on goal pursuit processes. Participants (N= 107) completed daily diaries over three consecutive days of SMH and three days of regular social media use. SMH was manipulated by blocking participants’ access to multiple social media platforms. The …

Perception Of Socioeconomic Status: A Meta-Analysis Of Manipulations, Jacinth Jia Xin Tan, Yong En Amos Tai May 2026

Perception Of Socioeconomic Status: A Meta-Analysis Of Manipulations, Jacinth Jia Xin Tan, Yong En Amos Tai

Research Collection School of Social Sciences

The causal effects of one’s socioeconomic status (SES) on outcomes are typically examined by experimentally manipulating SES self-perceptions based on one of three SES dimensions—absolute resource, relative resource, and general social position. We investigated the efficacy of these manipulations by systematically meta-analyzing their effects on SES self-perceptions. Based on 107 eligible samples (N = 26,203), manipulations of SES self-perceptions across the three SES dimensions were effective overall (g = 0.56–0.95). Explicit priming of absolute resource and relative resource manipulations comparing high versus low SES were consistently effective—although bias-corrected effects were attenuated—suggesting the importance of salient SES information and social comparisons. …

Political Costs And Strategic Corporate Communication, Christine Cuny, Jungbae Kim, Mihir N. Mehta May 2026

Political Costs And Strategic Corporate Communication, Christine Cuny, Jungbae Kim, Mihir N. Mehta

Research Collection School Of Accountancy

When subject to public scrutiny, do firms strategically use advertising to reduce expected political costs? Advertising can ease public concerns, thereby reducing the pressure on politicians to act harshly against scrutinized firms and their industries. We use repeated congressional testimony by industry members as a novel way to identify political scrutiny. Our central finding is that scrutinized industries increase their advertising spending 132 percent more in the electorates of politicians overseeing the hearings than in the electorates of other politicians. Further, strategic advertising is complementary to income-decreasing accounting choices and a substitute for lobbying. Overall, our study sheds light on …

Spiritual Gentrification Amid The Rise Of Platform Urbanism: "Wanghong Temples" And Emerging Buddhist Cultural Economies In Tianzhu Road, Hangzhou, China, Han Zhang, Junxi Qian, Lily Kong May 2026

Spiritual Gentrification Amid The Rise Of Platform Urbanism: "Wanghong Temples" And Emerging Buddhist Cultural Economies In Tianzhu Road, Hangzhou, China, Han Zhang, Junxi Qian, Lily Kong

Research Collection School of Social Sciences

This study scrutinizes how the Tianzhu Road in the Lingyin Community - a peri-urban area in Hangzhou ringed by a cluster of temples that constitutes a distinct spiritual enclave - has been reworked through a two-phase gentrification process driven by the spiritual aesthetics and platform logics. Drawing on a two-month ethnography and media content analysis, this study conceptualizes spiritual gentrification as a spiritual aesthetics and culture-oriented recalibration of urban space in which spiritual elements operate as symbolic capital, attracting culturally motivated entrepreneurs and aligning the spiritual atmosphere with slow-life values as an alternative to urban modernity. In particular, platform urbanism …

Brief Virtual Reality And Mixed Reality Mindfulness Breathing Exercise For Emotional Well-Being And Cognitive Functions In University Students: Within-Subjects Experimental Design Study, Zoey Khai Yee Eun, Charmaine Jiali Koh, Hwajin Yang, Adalia Yin Hui Goh, Meilan Hu, K Tennakoon Appuhamillage Sandeeshwara Kasturiratna, Andree Hartanto

Research Collection School of Social Sciences

Background: Mindfulness has been shown to enhance emotional well-being and cognitive performance, yet much of this evidence stems from interventions requiring prolonged practice, making them time-consuming and less accessible. Recent studies suggest that brief mindfulness sessions may also yield positive outcomes, but the effectiveness of such interventions in virtual reality (VR) and mixed reality (MR) remains underexplored. Objective: This study investigates the effects of brief mindfulness breathing exercises delivered through VR and MR on attentional and emotional restoration and self-control capacity. Methods: Using a within-subjects experimental design, 102 undergraduate participants (n=83, 81.4% female; mean age 20.87, SD 1.89) completed a …

The Restorative Effects Of Nature Exposure Via Virtual Reality On Well-Being, Self-Control, And Working Memory, Zoey K. Y. Eun, Hwajin Yang, Nicole R. Y. Chen, Andree Hartanto May 2026

The Restorative Effects Of Nature Exposure Via Virtual Reality On Well-Being, Self-Control, And Working Memory, Zoey K. Y. Eun, Hwajin Yang, Nicole R. Y. Chen, Andree Hartanto

Research Collection School of Social Sciences

The psychological benefits of nature exposure are vital for well-being in an increasingly urbanised world. While previous research has consistently demonstrated the restorative effects of natural environments on both physical and psychological health, findings on virtual nature simulations remain mixed, possibly due to the limited immersive quality of conventional displays. Virtual reality (VR), however, provides immersive visual and auditory engagement, making it a promising alternative for delivering nature-based experiences when direct exposure to real nature environments is unavailable. The present study examined the effects of VR-simulated nature on attentional and emotional restoration and self-control capacity, using a preregistered, within-subjects experimental …

A Stress-Induced Digital Escapism Framework For Understanding The Link Between Stress And Problematic Social Media Use, Hwajin Yang, Frosch Yi Xuan Quek, Xiu Hui Salin Yap, Yue Qi Germaine Tng, Gilaine Rui Ng May 2026

A Stress-Induced Digital Escapism Framework For Understanding The Link Between Stress And Problematic Social Media Use, Hwajin Yang, Frosch Yi Xuan Quek, Xiu Hui Salin Yap, Yue Qi Germaine Tng, Gilaine Rui Ng

Research Collection School of Social Sciences

Given that stress is a significant risk factor for problematic social media use, understanding the underlying psychological mechanisms is essential. We introduce the Stress-Induced Digital Escapism (SIDE) framework, which posits that negative internal emotional responses to external stressors may increase reliance on maladaptive emotion regulation strategies that fail to alleviate distress. These processes may, in turn, strengthen escapism motives that lead to seeking emotional relief through compulsive social media use. Using structural equation modeling (N = 238), we examined three integrated psychological pathways—negative stress reactions, maladaptive emotion regulation strategies, and escapism motives—as sequential mediators linking external demands to problematic social …

Research "Junkification" Is Caused By Researchers, Not Journals, Simon Sebastian Groome, Jose C. Yong, Norman P. Li May 2026

Research "Junkification" Is Caused By Researchers, Not Journals, Simon Sebastian Groome, Jose C. Yong, Norman P. Li

Research Collection School of Social Sciences

Concerns about declining research quality have increasingly been framed as “junkification,” whereby academic output expands in volume while declining in epistemic value. A recent paper by Rhodes and Linnenluecke (2025) attributes this trend to changes in publishing, arguing that research quality erodes as journals and publishers become increasingly oriented toward output quantity and metrics, driven by monetization. In 2009, Nobel Laureate James Watson remarked that scientific publishing in the mid-twentieth century was both easier and of a higher standard than today (Web of Stories, 2017). If publishing is much easier of late, as Rhodes and Linnenelucke (R&L) argued, then how …

Meritocracy And Equal Access To The Public Sector: A Comparative Analysis Of Accessibility To Public Sector Jobs And Public Services, Beomgeun Cho, Heasun Choi May 2026

Meritocracy And Equal Access To The Public Sector: A Comparative Analysis Of Accessibility To Public Sector Jobs And Public Services, Beomgeun Cho, Heasun Choi

Research Collection School of Social Sciences

This study investigates the impact of meritocracy on equal access to the public sector, focusing on public sector employment and services. While meritocratic principles promote impartiality and fairness in administrative processes, their effectiveness in improving equal accessibility remains understudied and contested. Drawing on the literature linking meritocracy to democratic stability, we argue that strong meritocratic systems enhance equal access to the public sector regardless of social groups and gender by fostering professional stewardship in the bureaucracy and strengthening checks and balances between bureaucrats and politicians. Our findings, drawn from a panel dataset consisting of 161 countries over 49 years, suggest …

Not Just Anyone: Living Situation Is Indirectly Associated With Cognitive Impairment Via Depressive Symptoms, Chin Hong Tan, Jacinth Jia Xin Tan

Research Collection School of Social Sciences

Objectives: Socially isolated individuals are at a greater risk of cognitive decline. We examined whether this relationship is dependent on the type of household living situation, living alone or living with others (spouse/ partner or relative/friend), and the indirect effects of depression. Methods: We evaluated 10,545 cognitively normal (CN, mean age = 71.6) and 9334 individuals with mild cognitive impairment (MCI, mean age = 72.9) cross-sectional data from the National Alzheimer's Coordinating Center. Participants' living situation was classified as living alone, living with spouse/partner, or living with a relative/friend. Cognitive function and depression were assessed by a neuropsychological battery and …

Patterns In Awareness And Uptake Of The Lpa Among Older Adults In Singapore, Paulin Tay Straughan, Emi Loh, Shu Fang Ng, Yi Wen (Chen Yiwen) Tan, Wensi Lim May 2026

Patterns In Awareness And Uptake Of The Lpa Among Older Adults In Singapore, Paulin Tay Straughan, Emi Loh, Shu Fang Ng, Yi Wen (Chen Yiwen) Tan, Wensi Lim

Research Collection School of Social Sciences

Findings from a survey with 7910 Singapore Life Panel members reveal that awareness of the Lasting Power of Attorney (LPA) was relatively high, but actual uptake remained low, with only one in three having made an LPA and pronounced gaps among lower socioeconomic groups. Despite this, attitudes towards LPA were generally positive, with perceived benefits centered on peace of mind and reducing burdens on family members. A major barrier to adoption is the misconception that children automatically have the legal authority to make decisions if parents lose mental capacity. Structural and psychological barriers, including cost, complexity, and limited guidance, further …

Improving Estimation Efficiency Via Regression-Adjustment In Covariate-Adaptive Randomizations With Imperfect Compliance, Liang Jiang, Oliver B. Linton, Haihan Tang, Yichong Zhang May 2026

Improving Estimation Efficiency Via Regression-Adjustment In Covariate-Adaptive Randomizations With Imperfect Compliance, Liang Jiang, Oliver B. Linton, Haihan Tang, Yichong Zhang

Research Collection School Of Economics

We study how to improve efficiency via regression adjustments with additional covariates under covariate-adaptive randomizations (CARs) when subject compliance is imperfect. We first establish the semiparametric efficiency bound for the local average treatment effect (LATE) under CARs. Second, we develop a general regression-adjusted LATE estimator which allows for parametric, nonparametric, and regularized adjustments. Even when the adjustments are misspecified, our proposed estimator is still consistent and asymptotically normal, and their inference method still achieves the exact asymptotic size under the null. When the adjustments are correctly specified, our estimator achieves the semiparametric efficiency bound. Third, we derive the optimal linear …

Using Satellite-Observed Geospatial Inundation Data To Identify The Impacts Of Floods On Firm-Level Performance: The Case Of China During 2000–2009, Pao-Li Chang, Fan Zheng May 2026

Using Satellite-Observed Geospatial Inundation Data To Identify The Impacts Of Floods On Firm-Level Performance: The Case Of China During 2000–2009, Pao-Li Chang, Fan Zheng

Research Collection School Of Economics

This paper compiles high-resolution geospatial inundation areas of China for the period 2000–2009 based on satellite imagery repositories filtered by the Global Flood Database (GFD). In parallel, we geocode a comprehensive firm-level dataset of China and combine these two sets of geospatial data to identify the set of inundated firms in each year of flood events, as well as the distances of all non-inundated firms from the inundated areas. Given the high-resolution inundation data, we adopt a generalized dynamic-panel specification to estimate dynamic and spatial spillover effects of floods on firm-level production activities (including outputs, capital and labor inputs, and …

Insolvency Law In The Global South: Lessons For The Global North, Aurelio Gurrea-Martinez May 2026

Insolvency Law In The Global South: Lessons For The Global North, Aurelio Gurrea-Martinez

Research Collection Yong Pung How School Of Law

Despite the influence of the Global North in many insolvency laws and practices in the Global South, this article shows that the Global South has innovated in many aspects of insolvency law. In some cases, these innovations consist of solutions that, with certain adjustments, have been imported from the Global North. In others, they are really ‘autochthonous innovations’ from the Global South. This article identifies both types of innovations, providing examples from jurisdictions such as Brazil, Chile, China, Colombia, Dominican Republic, India, Malaysia, Mexico, Myanmar, Peru, Philippines, Thailand and Uruguay. More importantly, it will be shown how those innovations from …

Childlessness And Advance Care Planning In Midlife And Late Adulthood: A Mixed-Methods Study In Singapore, Bussarawan Teerawichitchainan, Dahye Kim, Pearlyn Hui Min Hui, Christine Ho

Research Collection School Of Economics

Advance care planning (ACP) is critical for ensuring high-quality, cost-effective end-of-life care and is typically facilitated by spouses and adult children. Yet, the growing number of older adults without children has been overlooked in ACP research. This study employs a mixed-methods approach to examine ACP practices and perceptions among childless adults aged 50+ in Singapore, a rapidly aging society with one of the world's highest childlessness rates. Quantitative analyses draw on nationwide survey data (N = 1,500), complemented by interviews with childless respondents (N = 26). We examine multiple dimensions of ACP: formal ACP (e.g., living wills, Lasting Power of …

Detecting Doubt In Reflective Learning: A Learning Analytics Study With Large And Small Language Models, Eng Lieh Ouh, Kar Way Tan, Siaw Ling Lo, Yuhao Zhang May 2026

Detecting Doubt In Reflective Learning: A Learning Analytics Study With Large And Small Language Models, Eng Lieh Ouh, Kar Way Tan, Siaw Ling Lo, Yuhao Zhang

Research Collection School Of Computing and Information Systems

Reflective learning enhances understanding, especially when instructors promptly address difficulties raised in student reflections. Automated doubt detection can reduce time for instructors, yet existing classification approaches take substantial time for manual annotation and model training. This paper investigates whether large and small language models (LLMs, SLMs) can automate doubt detection without time-consuming training. Using a dataset of anonymized student reflections, we evaluate zeroshot, few-shot prompting, and multi-step reasoning against prior supervised classification baselines. We show that LLMs (GPT-4o, Claude-4, Gemini-2.5) surpass earlier F1 scores without prompting, while prompting further improves their performance. However, using proprietary LLMs can raise cost and …

The Downside Of Generosity: How Rare Giving Fosters Stronger Social Connection, Minkwang Jang, Shereen J Chaudhry, Ayelet Fishbach May 2026

The Downside Of Generosity: How Rare Giving Fosters Stronger Social Connection, Minkwang Jang, Shereen J Chaudhry, Ayelet Fishbach

Research Collection Lee Kong Chian School Of Business

Giving serves not only to benefit others and society but also to foster social connections between givers and recipients. However, more giving is not necessarily merrier. This research finds that social connection depends not only on the act of giving but also on how many others receive the gesture from the same giver. Rare givers—those who give to fewer recipients—are perceived as more socially connected to each recipient than broad givers—those who give to many (the rare giving effect). This effect emerges across diverse contexts, including interpersonal gift exchanges in both new and existing relationships and corporate donations. As a …
