Comadice: Offline Cooperative Multi-Agent Reinforcement Learning With Stationary Distribution Shift Regularization, The Viet Bui, Tien Mai, Hong Thanh Nguyen

Research Collection School Of Computing and Information Systems

Offline reinforcement learning (RL) has garnered significant attention for its ability to learn effective policies from pre-collected datasets without the need for further environmental interactions. While promising results have been demonstrated in single-agent settings, offline multi-agent reinforcement learning (MARL) presents additional challenges due to the large joint state-action space and the complexity of multi-agent behaviors. A key issue in offline RL is the distributional shift, which arises when the target policy being optimized deviates from the behavior policy that generated the data. This problem is exacerbated in MARL due to the interdependence between agents' local policies and the expansive joint …

Bootstrapping Language Models With Dpo Implicit Rewards, Changyu Chen, Zichen Liu, Chao Du, Tianyu Pang, Qian Liu, Arunesh Sinha, Pradeep Varakantham, Min Lin

Research Collection School Of Computing and Information Systems

Human alignment in large language models (LLMs) is an active area of research. A recent groundbreaking work, direct preference optimization (DPO), has greatly simplified the process from past work in reinforcement learning from human feedback (RLHF) by bypassing the reward learning stage in RLHF. DPO, after training, provides an implicit reward model. In this work, we make a novel observation that this implicit reward model can by itself be used in a bootstrapping fashion to further align the LLM. Our approach is to use the rewards from a current LLM model to construct a preference dataset, which is then used …

Out Of Many: The Study Of African American Diasporas On Social Media, Brianna M. Savage, Sindy Chapa

AMTP Proceedings 2025

This study uses a one-ad experimental design to test the effect of African American Vernacular English (AAVE) on Black Twitter, employing an online survey with a convenience sample. It examines cultural differences within Black African co-cultures, emphasizing how language variation influences consumer behavior in social media advertising. The findings indicate that Black consumers with positive attitudes toward advertisements featuring AAVE are more likely to engage with the content on Twitter and subsequently purchase the promoted brand. This supports attitude theory (Fishbein & Ajzen, 1975) and social distinctiveness theory (Grier, 2001), demonstrating a significant correlation between ethnic resolution and purchasing behavior.

Institutional Cross-Ownership Of Peer Firms And Revelatory Price Efficiency, Young Jun Cho, Holly I. Yang, Yue Zhao

Research Collection School Of Accountancy

We argue that cross-ownership increases the amount of private information in stock price, enhancing the ability of stock price to provide feedback to managers. Consistent with this argument, we find greater cross-ownership heightens a firm’s investment-q sensitivity. This effect is stronger for firms with a lower propensity for voluntary disclosure and for firms whose managers hold less private information. Furthermore, we find that cross-ownership is negatively associated with the sensitivity of a firm’s investment to its peers’ stock prices. Additionally, cross-ownership has a stronger impact on the investment-q sensitivity when measured among investors who trade more actively the …

Undergraduate Accounting Capstone: Enhancing Integration, Reflective Learning, And Workplace Transition For Future Professionals, Duan Ning, Magdeleine Lew, Clarence Goh, Poh Sun Seow, Gary Pan

Research Collection School Of Accountancy

This study examines whether a university capstone course focused on accounting data and analytics equips undergraduate accounting students with the relevant professional and technological skills for future work. There is concern that the traditional accounting curriculum, which often emphasizes theoretical knowledge and technical skills, may not sufficiently prepare students for the complex, data-driven environment in the workplace. Therefore, our study is important because professional and technological skills are essential skills that students need to thrive in complex, data-driven environments, and our study provides insights into whether a capstone course can equip students with these skills.

Decarbonising Digital Infrastructure And Urban Sustainability In The Case Of Data Centres, Felicia H. M. Liu, Karen P. Y. Lai, Bertrand Seah, Winston T. L. Chow

Research Collection College of Integrative Studies

This paper critically assesses the complex interplay between urban transitions of digitisation and sustainability. Building on a mixed-method research design, we unpack the challenges of decarbonising digital infrastructure while attending to urban sustainability goals in a land- and water-scarce country facing significant physical climate risks. We identify transferrable lessons on the economic, technological, and environmental synergies and trade-offs behind data centre development and argue that stewarding the global data centre sector towards sustainability requires an ecosystem-wide approach. We identify implementation gaps across five key dimensions: technological innovation, policy and regulation, finance, infrastructure, and people. We find that the progress and …

Characterising Reproducibility Debt In Scientific Software: A Systematic Literature Review, Zara Hassan, Christoph Treude, Michael Norrish, Graham Williams, Alex Potanin

Research Collection School Of Computing and Information Systems

Context: In scientific software, the inability to reproduce results is often due to technical issues and challenges in recreating the full computational workflow from the original analysis. We conceptualise this problem as Reproducibility Debt (RpD). Much research has been performed to propose solutions to tackle these issues across various computational science disciplines. It is essential to identify and accumulate existing knowledge on reproducibility issues and state-of-the-art solutions so as to provide researchers and practitioners with information that enables further research activities and RpD management in practice. Objective: In the context of scientific software, we aim to characterise RpD by providing …

Trait Mindfulness Is Associated With Enhanced Daily Affectivity And Cognition Independent Of Daily Stressors Exposure: Insights From Large-Scale Daily Diary Studies In The Us And Singapore, Yi Jing Chua, Andree Hartanto, Nadyanna M. Majeed

Research Collection School of Social Sciences

Trait mindfulness has been linked to various adaptive outcomes, including attenuated affective and cognitive responses to laboratory-induced stress. However, the role of trait mindfulness as a resilience factor against daily stressors exposures is less established. Across 2 studies, multilevel analysis was used to examine the relationships between trait mindfulness and daily affect and cognition, as well as affective and cognitive reactivity to and recovery from everyday stressor exposure. Trait mindfulness was significantly associated with higher daily positive affect in both studies, lower negative affect and cognitive failure, and lower cognitive reactivity to daily stressor exposure in Study 2. However, trait …

Registered Replication Report: Study 3 From Trafimow And Hughes (2012), Sean C. Rife, Et Al

Research Collection School of Social Sciences

Terror-management theory (TMT) proposes that when people are made aware of their own death, they are more likely to endorse cultural values. TMT is a staple of social psychology, featured prominently in textbooks and the subject of much research. The implications associated with TMT are significant because its advocates claim it can partially explain cultural conflicts, intergroup antagonisms, and even war. However, considerable ambiguity regarding effect size exists, and no preregistered replication of death-thought-accessibility findings exists. Moreover, there is debate regarding the role of time delay between the manipulation of mortality salience and assessment of key measures. We present results …

Ageing In Place: The Key To Receiving A Superaged Society, Paulin Tay Straughan, Yi Wen (Chen Yiwen) Tan, Qi Ting, Zidane Tiew, Zeyu Zheng, Rachel Wen Yi Ngu, Wei Tin Hiah

Research Collection School of Social Sciences

Ageing in place is the ability to remain in one’s community, where living conditions foster a sense of attachment that enhances holistic well-being. To facilitate this, both the built and social environments within which the home is nested must be conducive to successful ageing. This paper deconstructs the merits of ageing in place, specifically how attachment to the lived environment contributes to holistic well-being. We analysed data from 6020 participants in the Singapore Life Panel® using path models, where we examined three dimensions of ageing in place: place identity, continuity, and social inclusion. Five path analyses show that two dimensions …

Constructive Trusts In Malaysia: A Methodological Reappraisal, Hang Wu Tang, Ying Khai Liew

Research Collection Yong Pung How School Of Law

In recent times, Malaysian courts have resorted to a ritual incantation of unconscionability and the notion of a remedial constructive trust to justify a declaration of a constructive trust. This methodology is unhelpful for approaching constructive trusts and has led the law to develop in an unprincipled and unpredictable fashion. Our central thesis is that the key Malaysian decisions could have been decided on the basis of pre-existing legal principles upon which English and Commonwealth courts have declared a constructive trust. We argue that future courts ought to realign their methodology with the orthodox tradition of incremental development of the …

The Digitalization Of Insolvency Proceedings, Aurelio Gurrea-Martinez

Research Collection Yong Pung How School Of Law

Despite the international divergences existing in the design of insolvency law, there is a common feature of insolvency proceedings that, to a greater or lesser extent, is somehow universal: insolvency proceedings are generally costly and lengthy processes. For that reason, it is not surprising that a significant body of the literature on insolvency law deals with different mechanisms to make insolvency proceedings more efficient. This article examines how technology can contribute to that goal. To that end, it starts by reviewing how countries are deploying, or can deploy, technology in different aspects and stages of insolvency proceedings and how such …

What Is A Digital Twin Anyway? Deriving The Definition For The Built Environment From Over 15,000 Scientific Publications, Abdelrahman Mahmoud, Edgardo Macatulad, Binyu Lei, Matias Quintana, Clayton Miller, Filip Biljecki

Research Collection College of Integrative Studies

The concept of Digital Twins (DT) has attracted significant attention across various domains, particularly within the built environment. However, there is a sheer volume of definitions and the terminological consensus remains out of reach. The lack of a universally accepted definition leads to ambiguities in their conceptualization and implementation, and may cause miscommunication for both researchers and practitioners.We employed Natural Language Processing (NLP) techniques to systematically extract and analyze definitions of DTs from a corpus of more than 15,000 full-text articles spanning diverse disciplines. The study compares these findings with insights from an expert survey that included 52 experts. The …

The Insurgent Smart City: How A Social Movement Created An Alternative Imaginary Of The Smart City, Andrew Stokols

Research Collection College of Integrative Studies

Urban scholars have critiqued smart cities for their association with neoliberal governance, narrow focus on quantifiable aspects of urban systems, and failure to incorporate citizens’ needs or aspirations. The “smart city” remains a contested concept and as such is subject to reappropriation. Here, I analyze the case of an urban social movement, the 2019–2020 Hong Kong Anti-ELAB protests, as an alternative, “insurgent smart city.” Following from an earlier network analysis of Telegram channels used during the protests, I show how the communications system underpinning much of the protest action simultaneously enabled coordination while also remaining open to grassroots decision-making and …

A City Divided: Norfolk, Virginia And Public Higher Education In The Era Of Desegregation, John Edward Wiley V

History Theses & Dissertations

This thesis examines the 1978 suggested merger of predominantly white Old Dominion University and historically Black Norfolk State College (now Norfolk State University), two neighboring public higher education institutions. That year the Federal Department of Housing, Education, and Welfare (HEW) and the Office for Civil Rights (ORC) claimed that the two universities offered nine duplicative degree programs. According to HEW and the OCR, this duplication was a violation of Title VI of the 1964 Civil Rights Act, which prohibits discrimination in all public institutions receiving federal aid. The duplication also represented the last vestiges of Jim Crow segregation in the …

Leveraging Allies, Partners, And Technology: A Case Study Approach To Identifying Best Practices For Improving Us Military All-Domain Urban Training, Kevin Michael Felix

Graduate Program in International Studies Theses & Dissertations

In this study, the researcher explored urban training gaps, opportunities, and synergies across the United States and five Allied and partner nations, and how synthetic training environments (STE) technologies should be optimized now and in the future to improve US all-domain urban training. The researcher adopted a qualitative multiple case study approach, analyzing military doctrine, urban warfare training strategies, and infrastructure in the United States, Germany, France, Britain, Israel, and Singapore to establish best practices across these countries. Urban warfare requires specialized skills to negotiate terrain, including high-rise buildings, subterranean networks, and dense civilian populations. However, the existing U.S. military …

Defining A 'Cells To Society' Research Framework For Appendiceal Tumours, Andreana N Holowatyj, Michael J Overman, Konstantinos I Votanopoulos, Andrew M Lowy, Patrick Wagner, Mary K Washington, Cathy Eng, Wai Chin Foo, Richard M Goldberg, Mojgan Hosseini, Kamran Idrees, Douglas B Johnson, Ardaman Shergill, Erin Ward, Nicholas C Zachos, Deborah Shelton

Tumours of the appendix — a vestigial digestive organ attached to the colon — are rare. Although we estimate that around 3,000 new appendiceal cancer cases are diagnosed annually in the USA, the challenges of accurately diagnosing and identifying this tumour type suggest that this number may underestimate true population incidence. In the current absence of disease-specific screening and diagnostic imaging modalities, or well-established risk factors, the incidental discovery of appendix tumours is often prompted by acute presentations mimicking appendicitis or when the tumour has already spread into the abdominal cavity — wherein the potential misclassification of appendiceal tumours as …

From Flames To Change: An Exploration Of Housing, Fire, And Inequity, Helen Underhill, Charles R. Jennings, Brian Meacham, Danielle Antonellis

Publications and Research

Housing and fire safety are deeply connected: inadequate and poorly maintained housing poses heightened fire risk for occupants. An individual or household’s housing situation (including limited or constrained choice) interacts with issues such as affordability, access, location, quality, safety, occupancy levels, tenure type, and resident or immigration status. These dynamics shape vulnerability, and inequity becomes most visible in the event of a fire. The extreme end of this spectrum includes the unhoused, who occupy structures entirely outside of regulatory systems with little or no fire protection.

Manual Therapy For Fibrosis-Related Late Effect Dysphagia In Head And Neck Cancer Survivors: The Mantle Nonrandomized Clinical Trial, Holly Mcmillan, Carla L Warneke, Sheila Buoy, Christine Porsche, Kiara Savage, Stephen Y Lai, Clifton D Fuller, Katherine A Hutcheson

Faculty, Staff and Student Publications

Importance: Late radiation-associated dysphagia (RAD) after head and neck cancer (HNC) treatment is challenging and commonly treatment refractory, with fibrosis stiffening connective tissues and compressing peripheral nerve tracts, contributing to diminished strength and possibly denervation of swallowing muscles. Manual therapy (MT), while common for cancer-related pain and other indications, remains largely unstudied for fibrosis-related late RAD.

Objective: To determine the feasibility and safety of MT, estimate effect size and durability of MT for associated improvements in cervical range of motion (CROM), and examine functional outcomes after MT in survivors of HNC with fibrosis-related late RAD.

Design, setting, and participants: This …

Characterization Of A Time-Resolved, Real-Time Scintillation Dosimetry System For Ultra-High Dose-Rate Radiation Therapy Applications, Alexander Baikalov, Daline Tho, Kevin Liu, Stefan Bartzsch, Sam Beddar, Emil Schüler

Faculty, Staff and Student Publications

Purpose: Scintillation dosimetry has promising qualities for ultra-high-dose-rate (UHDR) radiation therapy (RT), but no system has shown compatibility with mean dose rates (DR¯) above 100 Gy/s and doses per pulse (Dp) exceeding 1.5 Gy typical of UHDR (FLASH)-RT. The aim of this study was to characterize a novel scintillation dosimetry system with the potential of accommodating UHDRs.

Methods and materials: We undertook a thorough dosimetric characterization of the system on an UHDR electron beamline. The system's response as a function of dose, DR¯, Dp, and the pulse dose-rate (DRp) was investigated, as was the system's dose sensitivity (signal per unit …

Equity And Clarity: The Impact Of Tyler V. Hennepin County On Property Taxation And Homeowners’ Rights, Analy Feigel

Cardozo Law Review

This Note explores the implications ofthe U.S. Supreme Court's ruling in Tyler v. Hennepin County, which significantly impacts property taxation and foreclosure laws. The Court ruled that property owners are entitled to surplus proceeds following a tax foreclosure, setting a new precedent by deeming it unconstitutional for governments to retain surplus proceeds without just compensation. Tyler clarified property rights under the Fifth Amendment, affirming that owners have a constitutional right to the surplus value of their foreclosed properties, even if local statutes do not explicitly allow it.

Further, this Note also addresses unresolved issues following Tyler's ruling, including how the …

The Role Of Chatgpt In Personal Statements For Plastic Surgery Residency Applications: Program Directors' Perspective., Krishna A Patel, Carly J Suriano, Jeffrey E Janis

Adolescents and young adults with bipolar disorder often experience cognitive deficits that hinder academic performance and social interactions, affecting long-term outcomes. Identifying cognitive impairments is crucial for improving clinical management of bipolar disorder. Use of cognitive screeners is recommended to identify cognitive difficulties and for ongoing assessment. Although cognitive screeners are effective with adults, their use with adolescents and young adults is limited. This project assessed clinicians' attitudes and practices regarding cognitive screening of adolescents and young adults with bipolar disorder. The National Network of Depression Centers (NNDC) Child and Adolescent Mood Disorders Task Group developed a survey for clinicians …

A New Multiple Imputation Method For High-Dimensional Neuroimaging Data, Tong Lu, Peter Kochunov, Chixiang Chen, Hsin-Hsiung Huang, L Elliot Hong, Shuo Chen

Faculty, Staff and Student Publications

Missing data are a prevalent challenge in neuroimaging, with significant implications for downstream statistical analysis. Neglecting this issue can introduce bias and lead to erroneous inferential conclusions, making it crucial to employ appropriate statistical methods for handling missing data. Although the multiple imputation is a widely used technique, its application in neuroimaging is severely hindered by the high dimensionality of neuroimaging data, and the substantial computational demands. To tackle the critical computational challenges, we propose a novel approach, High dimensional Multiple Imputation (HIMA), based on Bayesian models specifically designed for large-scale neuroimaging datasets. HIMA introduces a new computational strategy to …

The Impact Of Atlas Parcellation On Functional Connectivity Analysis Across Six Psychiatric Disorders, Xiaoya Wu, Chuang Liang, Juan Bustillo, Peter Kochunov, Xuyun Wen, Jing Sui, Rongtao Jiang, Xiao Yang, Zening Fu, Daoqiang Zhang, Vince D Calhoun, Shile Qi

Faculty, Staff and Student Publications

Neuropsychiatric disorders are associated with altered functional connectivity (FC); however, the reported regional patterns of functional alterations suffered from low replicability and high variability. This is partly because of differences in the atlas and delineation techniques used to measure FC-related deficits within/across disorders. We systematically investigated the impact of the brain parcellation approach on the FC-based brain network analysis. We focused on identifying the replicable FCs using three structural brain atlases, including Automated Anatomical Labeling (AAL), Brainnetome atlas (BNA) and HCP_MMP_1.0, and four functional brain parcellation approaches: Yeo-Networks (Yeo), Gordon parcel (Gordon) and two Schaefer parcelletions, among correlation, group difference, …
