Data Is The New Gold: A Singapore Perspective On The Duty Of Care Concerning A Dataset’S Role In Contributing To Bias And Ai Hallucinations, Daniel Seah

Research Collection College of Integrative Studies

Amidst the trends and advances in Artificial Intelligence (AI) techniques, the dataset’s key role in creating AI harms is a constant. Yet the literature’s attention is typically focussed on the machinelearning’s role, from which the dataset’s role is examined usually in terms of its potential for bias. Datasets also contribute to AI hallucinations. Again, the literature focuses on the composite roles of datasets and AI models in hallucinations, in isolation from a dataset’s contributory role in creating bias. Therefore, the overlapping and distinctive roles of datasets, as a dual contributor, are understudied in the literature. Through the legal concept of …

Competition And Innovation In The Financial Sector: Evidence From The Rise Of Fintech Start-Ups, Doina Caragea, Theodor Florian Cojoianu, Mihai Dobri, Andreas Hoepner, Oana Peia, Davide Romelli

Research Collection College of Integrative Studies

This paper provides new evidence on the effects of entry on incumbents’ incentives to innovate by examining the rise of FinTech innovations over the period 2000-2016. We employ machine learning algorithms to classify a large sample of patent applications into five types of FinTech innovations. We then show that greater competition from innovators outside the financial sector increases the probability that incumbent financial firms will innovate. Our identification strategy exploits the variation over time in the share of FinTech patent applications by non-financial start-ups relative to incumbent financial firms, as a proxy for competitive pressures from outside the financial industry. …

Genome-wide significant loci for metformin response in type 2 diabetes reported elsewhere have not been replicated in the Diabetes Prevention Program (DPP). To assess pharmacogenetic interactions in prediabetes, we conducted a genome-wide association study (GWAS) in the DPP. Cox proportional hazards models tested associations with diabetes incidence in the metformin (MET; n = 876) and placebo (PBO; n = 887) arms. Multiple linear regression assessed association with 1-year change in metformin-related quantitative traits, adjusted for baseline trait, age, sex, and 10 ancestry principal components. We tested for gene-by-treatment interaction. No significant associations emerged for diabetes incidence. We identified four genome-wide …

Factors Associated With Choice Of Behavioural Weight Loss Program By Adults With Obesity, Yasaman Jamshidi-Naeini, Susan B Roberts, Stephanie Dickinson, Arthur Owora, Jon Agley, Roger S Zoh, Xiwei Chen, David B Allison

Children’s Nutrition Research Center Staff Publications

We assessed the preference for two behavioural weight loss programs, Diabetes Prevention Program (DPP) and Healthy Weight for Living (HWL) in adults with obesity. A cross-sectional survey was fielded on the Amazon Mechanical Turk. Eligibility criteria included reporting BMI ≥30 and at least two chronic health conditions. Participants read about the programs, selected their preferred program, and answered follow-up questions. The estimated probability of choosing either program was not significantly different from .5 (N = 1005, 50.8% DPP and 49.2% HWL, p = .61). Participants' expectations about adherence, weight loss magnitude, and dropout likelihood were associated with their choice (p <  .0001). Non-White participants (p = .040) and those with monthly income greater than $4999 (p = .002) were less likely to choose DPP. Participants who had postgraduate education (p = .007), did not report high serum cholesterol (p = .028), and reported not having tried losing weight before (p = .025) were more likely to choose DPP. Those who chose HWL were marginally more likely to report that being offered two different programs rather than one would likely affect their decision to enrol in one of the two (p = .052). The enrolment into DPP and HWL was balanced, but race, educational attainment, income, previous attempt to lose weight, and serum cholesterol levels had significant associations with the choice of weight loss program.

Disaffection And Othering: Beyond Our Coordinates, Christen Kadkhodai

War, Diplomacy, and Society (MA) Theses

"Othering” is just one of many tools nations use during war time to garner support for the war effort. “Othering” in media often goes undetected, a subtle framing of one’s own viewpoint as the viewpoint and the gaze, often at the exclusion and alienation of others. This collection of essays explores how individuals and institutions “Othered” during wartime. Essays “A Review of Walt Disney’s Life and ‘Othering’” and “Walt Disney’s ‘Reluctant Dragon’ and the 1941 Strike,” study how and why Walt Disney “Othered” certain audiences in his films The Reluctant Dragon, Saludos Amigos, and The Three Caballeros. …

Key Determinants Of Life Satisfaction In Older Adults, Barry Nuqoba, Yi Wen Tan, Yen Cong Wong, Wensi Lim

ROSA Research Briefs

Life satisfaction constitutes a fundamental facet of wellbeing, exerting an influence on an individual's mental and emotional state (Zissi & Barry, 2006). Among older adults, elevated levels of life satisfaction are frequently linked to a more optimistic outlook, contributing to improved health and resilience (Khodabakhsh, 2022; Zheng, Huang, & Fu, 2020). This in turn enhances societal involvement, both in the professional and social domains (Khodabakhsh, 2022). It is also vital to acknowledge that life satisfaction is a multifaceted construct, intricately influenced by an array of external and internal determinants. Life satisfaction is essentially a subjective judgement and assessment of one’s …

An Examination Of Faith And Faith-Based Practices On Help-Seeking Behaviors Among Afro-Caribbean Immigrants In The United States, Shanta K. Pamphile

Theses, Dissertations and Culminating Projects

This dissertation presents the findings of a qualitative study exploring the negotiation of faith among Afro-Caribbean immigrants regarding their decision to seek support with the stress of adjusting to the United States. The analysis revealed that Afro-Caribbean immigrants experience high-stress levels as they pursue economic, professional and social advancement in the United States. The persistence of these stressors, with long-lasting residual effects, warrants psychological support. Migrants, although relying heavily on their faith for support with this stress, are willing to seek support. However, they must work through worries of caution and trust and need to discern whether seeking support may …

Investigating The Effects Of E219 Mutations In M. Tuberculosis Indole-3-Glycerol Phosphate Synthase, Cinthya Moran

Theses, Dissertations and Culminating Projects

Tuberculosis (TB) is a serious infectious disease caused by Mycobacterium tuberculosis. Tuberculosis drug resistance is increasingly a problem, but recent research has provided results that suggest Indole-3-Glycerol Phosphate Synthase (IGPS) could be a potential drug target. IGPS is an enzyme that catalyzes the fourth step in the tryptophan biosynthesis pathway, a crucial process for optimal Mycobacterium tuberculosis growth. In this research, we studied IGPS from Mycobacterium tuberculosis (MtIGPS) to shed light on a particular conserved residue that has not been studied in depth in any IGPS homolog.

Theses, Dissertations and Culminating Projects

Societal benefits and ecosystem services provided by barrier islands are at risk as these landforms evolve rapidly in response to system changes including an increasing rate of sea-level rise and changing storm patterns. To prevent retreat or drowning, the expected response of natural barrier islands, and preserve benefits provided by barrier islands, significant investments are made at developed barrier islands to stabilize ocean and bay shorelines. Maintaining stable shorelines may not be sustainable in the future due to changing environmental, financial, and political conditions. Decadal to centennial-scale alongshore barrier island evolution at Long Beach Island, New Jersey is analyzed to …

An Investigation Of Trauma Cycles And The Omnipresent Parent In A.S. King's Please Ignore Vera Dietz, Emily Orlando

Theses, Dissertations and Culminating Projects

In 2010 A.S. King published her young adult novel Please Ignore Vera Dietz. The novel focuses on several characters who are navigating both intrapersonal and interpersonal conflicts while also coping with various traumas. While Young Adult Literature does not usually prominently feature parental figures, King chooses to include several parents in the text, and even gives one parent a first-person narrative. Due to King’s unusual choice she is able to illustrate the manner in which trauma can move from one generation to the next. These depictions of complete “trauma cycles” allows for a more comprehensive and empathetic understanding of how …

Understanding The Induction Experience Of Licensed Mental Health Counselors Working In New York City School Based Mental Health Clinics, Raymond Allen Blanchard Iii

Theses, Dissertations and Culminating Projects

The mental health symptoms and diagnosis rates of children and adolescents is rising in the United States (Oliver & Abel, 2018). To support the growing mental health rates and offset the work being provided by school counselors, school social workers, and school psychologists, schools are contracting with community mental health agencies to provide mental health counseling services in the school setting (Weist et al., 2017b). For some community mental health agencies, they are opening school based mental health clinics (SBMHCs) to provide more comprehensive mental health counseling services to reduce families having to seek services in their community (Weist et …

Density And Occupancy Of Mammals Along An Urban To Rural Gradient In Northwest Arkansas, Leah E. Mctigue

Graduate Theses and Dissertations

Human development is a rapidly expanding phenomenon impacting wildlife communities globally. As the human footprint expands, natural greenspace and nature reserves become fragmented and isolated. Wildlife species and communities respond to these changes in different ways. Urban exploiters persist in more urban areas and are able to take advantage of anthropogenic subsidies (food, shelter, etc). Urban avoiders, however, are species that may be pushed out of developed areas or occur in lower densities relative to undisturbed areas. Northwest Arkansas is an optimal location to study the impacts of urbanization on wildlife communities, as the current human population is expected to …

Integrated And Monolithic Iii-Nitride Devices Grown By Mbe, Rohith Allaparthi

Graduate Theses and Dissertations

III-Nitride (III-N) semiconductors with wide bandgap (WBG) characteristics offer promising advancements for high power density, high voltage, and high-frequency applications, presenting a promising alternative to traditional silicon (Si) technology. However, native substrate material for the majority of WBG semiconductors is still not commercially affordable. Because of its highly mature progression, utilizing standard Si wafers as substrates is a cost-effective alternative. This dissertation explores the development of electronic devices based on III-N thin films, grown monolithically via molecular beam epitaxy (MBE), followed by several processing techniques. Initially, a heterojunction p-n diode is realized, incorporating the growth of single-crystal WBG AlN films …

Index Fund Ownership And Stock Price Efficiency: Evidence From Quarterly Earnings Seasons, Joe López Vilaró

Graduate Theses and Dissertations

While prior research argues that individual investors benefit from a switch to passive investment in index funds (French 2008, Bond and García 2022), higher levels of index fund ownership of firm shares lead to competing factors that influence a firm’s price efficiency (i.e., the speed and accuracy with which a firm’s stock price reflects investor consensus on the information provided about a firm). If relative investor sophistication increases as index fund ownership increases, there is a benefit to the firm’s price efficiency. Yet, more shares held passively limit the shares available for investors to actively incorporate firm news, adversely impacting …

Treating High Salinity Produced Water Using Hybrid Membrane Processes: Electrocoagulation-Microfiltration/Ultrafiltration-Membrane Distillation-Crystallization, Mahmood Gheni Jebur

Graduate Theses and Dissertations

Produced water (PW) is considered the largest industrial wastewater stream in the world. PW generated from oil and gas operations generally contains a range of contaminants including high total dissolved solids, high total suspended solids, polar and nonpolar organic compounds, and low surface tension dissolved species. Treating PW is very challenging and applying only membrane-based technologies is not sufficient due to membrane fouling, which affects their long-term performance. Hence, integrated membrane processes are required to treat PW effectively. Hybrid membrane processes, which may result from combining a conventional process with a membrane separation, could be used to address the issues …

Explicit And Implicit Measurements Of Sensory And Emotional Responses To Stimuli In Children With Autism Spectrum Disorder, Asmita Singh

Graduate Theses and Dissertations

Autism Spectrum Disorder (ASD) is a developmental disability that causes significant social, communication, and behavioral challenges and it is often involved in sensory processing issues that lead to feeding problems. While our understanding of how sensory responses differ in people with ASD is limited, past studies indicated atypical responses to certain stimuli. If these stimuli can be identified, they could be good indicators to identify the risk of autism in young children. The main objective of this dissertation was to identify a specific stimulus leading autistic children to exhibit atypical responses in terms of sensory or emotional aspects. Children between …

A Comparison Of Intelligent Agent Technology And Traditional Preference Assessment Implementation Methods For Preservice Speech-Language Pathologists, Brenna R. Griffen

Graduate Theses and Dissertations

Identifying preferred stimuli is an initial step in many evidence-based educational programs for young children. Preference assessments, such as the Multiple Stimulus Without Replacement (MSWO), provide an empirically validated way of identifying and ranking these stimuli. Traditional methods of training professionals to implement MSWO often require the presence of an expert trainer, involve lengthy instructional time, require additional training to transfer skills into the clinical or classroom setting, and necessitate follow-up training to maintain skills over time. Intelligent agent technology may overcome these challenges by providing professionals with easily accessible, consistent instruction. The purpose of the current study was to …
