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. To examine these issues, we …

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 …

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 …

The technology is constantly evolving and improving with the intentions to make life easier, however, research has revealed unique challenges VCIs pose for Deaf and hard-of-hearing (DHH) users due to reliance …

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 …

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, …

Introduction: To investigate the associations of education level, marital status, and physical activity with dementia risk and brain MRI markers.

Methods: Data from six community-based samples from the Cross-Cohort Collaboration Consortium were analyzed. Self-reported education level, marital status, and physical activity at age 60 to 75 years were harmonized. Subsamples of participants with brain MRI markers at time of exposure were selected. Associations with dementia risk and cross-sectional MRI markers were meta-analyzed.

Results: Higher education level was associated with lower dementia risk (hazard ratio [HR] = 0.65, 95% confidence interval [CI] = 0.59; 0.72 vs low level) but not significantly …

Underlying Mechanisms Of The Effect Of Microfines Of Manufactured Sand On Non-Linear Structural Build-Up Of Cement Paste, Jiang Zhu, Jiaping Liu, Kamal H. Khayat, Xin Cheng, Wei Zhao, Zhen Li, Xin Shu, Yongbo Huang

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The rheological properties of cement-based materials made with manufactured sand vary with the content and physio-chemical properties of microfines in the sand. However, the evaluation of rheological properties regarding the structural build-up at early-age hydration remains challenging for the cementitious materials prepared with different manufactured sands, due to complicated underlying structuration mechanisms. This paper studies the effect of disparate microfines of different manufactured sands on the non-linear growth of static yield stress of cement pastes at rest. The paste mixtures were prepared with 0.40 and 0.275 water-to-cement mass ratio (W/C) and had a fixed mini-slump flow of 240 ± 5 …

Quality Assurance Framework For Recovered Binders And Aggregates From Asphalt Mixtures Incorporating Recycled Materials, Eslam Deef-Allah, Magdy Abdelrahman

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

This study proposes that a proactive quality assurance (QA) framework for asphalt mixes with recycled materials, i.e., reclaimed asphalt pavement and recycled asphalt shingles, should be developed. Quality control (QC) is generally concerned with the contractor's obligation to produce mixes which meet the job mix formula (JMF) targets. However, QA considers the variability in fabrication processes and materials and offers monitoring by evaluating the contractor's performance. Although both aggregate gradations and asphalt contents were within the JMF specifications, the recovered binders revealed significant differences from the contract binders in the JMF. Rheological tests indicated increased stiffness and elasticity but reduced …

Co2 Utilization For Cementitious Materials - A Review, Seongho Han, Jae Hong Kim, Rohitashva Kumar Singh, Surendra P. Shah

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

This review examines methods for utilizing CO₂ in construction materials to reduce the carbon footprint of cement and concrete production. Key approaches include direct carbonation of calcium silicates through CO₂ curing, use of industrial by-products as supplementary cementitious materials activated by carbonation, production of alternative binders and aggregates via CO₂ treatment of waste materials, injection of CO₂ into fresh concrete mixtures, and use of CO₂-dissolved mixing water. Both academic research and emerging commercial technologies are covered. While these methods show promise for enhancing material properties and sequestering CO₂, challenges remain in optimizing …

Approximations And Bounds For Optimal Controls Via Finite Fourier Series, Gabriel Nicolosi, Terry Friesz, Christopher Griffin

Engineering Management and Systems Engineering Faculty Research & Creative Works

This work considers the problem of approximating initial condition and time-dependent optimal control and trajectory surfaces using multivariable finite Fourier series. A modified Augmented Lagrangian algorithm for translating the optimal control problem into an unconstrained optimization one is proposed. A quadratic control problem in the context of Newtonian mechanics is solved to demonstrate the proposed algorithm and various computational results are presented. Use of automatic differentiation is explored to circumvent the elaborated gradient computation in the first-order optimization procedure. Furthermore, mean square error bounds are derived for the case of one and two-dimensional Fourier series approximations, suggesting a general bound …

Exploring Dynamic Extreme Dependence Of Oil And Agricultural Markets, Khalid M. Kisswani, Amine Lahiani, Mahelet G. Fikru

Economics Faculty Research & Creative Works

This study examines the dynamic extreme dependence between oil markets and a set of non-exploited agricultural assets (Barley, coffee, maize, rice, sorghum, sugar, wheat) prices using 1990–2023 monthly prices data. Our time-varying copula models allow us to investigate nonlinear and asymmetric dependence between pairwise assets. We find evidence of positive exceedance correlation at small and medium quantiles/thresholds and negative exceedance correlation for quantiles higher than 0.6 for five out of seven food assets. Findings also indicate a tent-shaped quantile dependence for all food assets and demonstrate a time variation in the association path between oil and food asset returns. Important …

Analytical Dispatch Strategies For Pumped Storage Hydro: A Conditional Dynamic Programming Approach To Discontinuous Multi-Period Optimization Problems, Jian Liu, Jianwen Zhang, Zaiwu Gong, Donald C. Wunsch, Rui Bo

Electrical and Computer Engineering Faculty Research & Creative Works

The increasing integration of renewable energy sources like wind and solar poses significant challenges to secure and stable grid operation. Energy storage systems, particularly pumped storage hydro (PSH), play a crucial role in balancing power supply and demand. Traditional analytical studies of PSH economic dispatch problems often assume zero lower bounds for generating and pumping rates to simplify analysis and derive analytical solutions for multi-period optimization problems. However, the inherent mechanical design constraints of PSH require non-zero minimum flow rates for efficient operation. We analyze two scenarios, merchants having PSH only and merchants having both PSH and wind farms. In …

Transforming Optical Vernier Effect Into Coherent Microwave Interference Towards Highly Sensitive Optical Fiber Sensing, Ruimin Jie, Jie Huang, Chen Zhu

Electrical and Computer Engineering Faculty Research & Creative Works

The optical Vernier effect has garnered significant research attention and found widespread applications in enhancing the measurement sensitivity of optical fiber interferometric sensors. Typically, Vernier sensor interrogation involves measuring its optical spectrum across a wide wavelength range using a high-precision spectrometer. This process is further complicated by the intricate signal processing required for accurately extracting the Vernier envelope, which can inadvertently introduce errors that compromise sensing performance. In this work, we introduce a novel approach to interrogating Vernier sensors based on a coherent microwave interference-assisted measurement technique. Instead of measuring the optical spectrum, we acquire the frequency response of the …

Financial Harm In Gambling Help-Seeking: A Scoping Review, Elizabeth Halle Smith

Electronic Theses and Dissertations Archive

Gambling literature often references financial harm, an objective experience following gambling-related financial losses. Financial harm alongside emotional distress has been implicated in help-seeking for problem gambling, indicating the importance of subjective reactions to financial harm and its perceived severity. It is unclear whether the gambling literature measures both objective and subjective experiences of financial harm. To explore the implications of financial harm on gambling help-seeking behaviors, this scoping review explored how the gambling literature measures financial harm among gambling help-seeking populations. In 84 articles, financial harm was defined through objective metrics such as debt and bankruptcy. Although financial harms were …

What Is Sports Wagering? A Scoping Review, Ji Wan Wan Son

Electronic Theses and Dissertations Archive

Sports wagering has been defined as wagering on the outcome of an athletic competition, specifically a single-game sporting event. In recent years, this definition has proven insufficient to account for the different technological opportunities to engage in sports wagering. The goal of this scoping review was to examine the terms, definitions, and specific gambling activities that comprise sports wagering and to review operationalizations of sports wagering measurement. A systematic search was used to extract (e.g., betting, gambling), definitions, gambling modes (online vs. in-person), encompassed activities, and measurement methods. Seventy-seven articles reveal similarities and discrepancies in the definitions and operations of …
