Attachment To Artificial Intelligence: Development Of The Ai Attachment Scale, Construct Validation, And The Psychological Mechanisms Of Human-Ai Attachment, K Tennakoon Appuhamillage Sandeeshwara Kasturiratna, Andree Hartanto

Research Collection School of Social Sciences

Artificial intelligence (AI) systems are increasingly integrated into daily life, not only as tools but also as social partners that people may turn to for interaction and support. This raises important questions about whether, how, and why individuals form attachment-like bonds with AI, and the psychological implications of such attachments. Across five studies involving 1259 unique participants from Singapore and the U.S., the current work developed and validated the 15-item AI Attachment Scale and investigated the dispositional and motivational factors associated with attachment to AI, as well as its emotional and social outcomes. The AI Attachment Scale displayed strong psychometric …

The Good Life Paradox, Matthew Hammerton

Research Collection School of Social Sciences

Picture two people on their deathbeds. The first lived comfortably, surrounded by loving family and friends, enjoying diverse pleasures and achievements throughout a long life. The second dedicated herself entirely to fighting injustice, achieving remarkable social change, but at great personal cost. Who lived the better life?Your answer might depend on what you mean by ‘better’. Philosophers have long recognized that when we call a life ‘good’ we can mean different things. So we could be talking about a life’s moral goodness – how virtuous the person was – or its prudential goodness – how well the life went for …

Effectiveness Of Cognitive And Behavioral Interventions In The Treatment Of Schizophrenia: An Umbrella Review Of Meta-Analyses, Gabriel Xing Da Tan, Andree Hartanto, Zoey Khai Yee Eun, Meilan Hu, Kean J. Hsu, Nadyanna M. Majeed

Research Collection School of Social Sciences

Background: Cognitive and behavioral interventions have risen in popularity both as an adjunctive treatment to antipsychotic medication and as an alternative treatment for schizophrenia. With the growing number of such interventions, we performed an umbrella review to provide a comprehensive summary comparing the effectiveness of the different interventions among populations with schizophrenia. Methods: This umbrella review included meta-analyses evaluating cognitive and behavioral interventions for schizophrenia. Following PRISMA guidelines, the initial search yielded 4888 records, and after a three-stage screening procedure, 33 meta-analyses met the inclusion criteria for the final analysis. Results: Our findings from the 33 meta-analyses support the efficacy …

Contextual Stress Profiles And Trajectories Of Internalizing Symptoms Among Adolescents In Mexican Immigrant Families, Su Yeong Kim, Wen Wen, Kiera M. Coulter, Wei Xiang Sim, Tianlu Zhang, Jingyi Shen, Yang Hou, Yishan Shen, Ka I. Ip

Research Collection School of Social Sciences

Contextual stress experiences in early adolescents may predict distinct trajectories of depressive symptoms and anxiety across the course of adolescence. Data from 604 Mexican-origin adolescents collected from 2012 to 2020 (54% female; Mage = 12.92, SD = 0.92) showed that youth with high stress levels in multiple domains (Broadly Stressed) and those with high stress in language brokering domain only (Language Brokering Stressed) had similar levels of internalizing symptoms in early adolescence, and both groups reported higher stress than youth experiencing occasional levels of stress across domains (Occasionally Environmentally Stressed). However, youth in the Language Brokering Stressed group experienced slightly …

Novice Instructors Can Make Satisfying Video Lectures By Using Familiar Techniques: A Repeated-Measures Test Of Video Lecture Formats And Learner Satisfaction Theory, Sonny Rosenthal, Stuart Braiman, Dawn Z. Y. Poh

Research Collection College of Integrative Studies

Research has shown that composite video lectures lead to higher learner satisfaction than other video lecture formats, but this finding has not been replicated among novice instructors. In this study, six PhD students created two video lectures on different topics. One used the picture-in-picture (PiP) format, while the other used the video composite format. Undergraduate student participants (N = 185) watched both video lectures by a single instructor and rated them on several variables. Contradicting prior research, the participants rated the composite video as having lower content quality (Cohen’s d = -0.35) and instructor-content interaction (Cohen’s d = -0.17) than …

Navigating Ai-Nature Frictions: Autonomous Vehicle Testing And Nature-Based Constraints, Prerona Das, Orlando Woods, Lily Kong

Research Collection College of Integrative Studies

In cities, the application of Artificial Intelligence (AI) is being directed towards transforming different aspects of urban life. These applications take material form in urban spaces, with autonomous vehicles (AVs) providing a prominent example. AI systems rely on large volumes of data on their surroundings to refine the algorithms and enhance the accuracy of prediction for operational efficiency and safety. However, such algorithmic learning and execution can present challenges when dealing with the unpredictable, complex, and dynamic aspects of urban spaces. Nature is a paradigmatic example of such unpredictability, because natural phenomena usually defy consistent patterns and precise data-based modelling. …

Assembling Diasporic Faith Amidst China’S Rise: (De)Territorialization And The Multi-Scalar Production Of The Guangze Zunwang Cult In The Chinese Diaspora, Ningning Chen, Orlando Woods

Research Collection College of Integrative Studies

Faith in the Chinese diaspora has become increasingly vibrant in the context of China’s rise as a global power. Drawing on multi-sited ethnographic research exploring the temple networks of the Guangze Zunwang cult, this paper advances an assemblage approach to understanding diasporic faith and investigating its multi-scalar becoming by exploring three areas of inquiry. The first investigates the evolving development of the Guangze Zunwang cult and its formation into a faith assemblage based on temple alliances, which bring people, deities, institutions, places and material objects together across (national) borders. The second explores the multi-scalar becoming in which faith assemblages are …

Rethinking Singer: Toward A Valid Argument For Helping The Global Poor, Joshua Luczak

Research Collection College of Integrative Studies

For more than 50 years, Peter Singer has argued that we are required to donate to aid agencies. While many commentators have rejected one or more of his premises, no one appears to have challenged the argument’s validity, and it is often assumed to be valid even by critics. This article demonstrates that Singer’s common-sense morality arguments for donating to aid agencies are invalid. It then reconstructs a valid version of the argument consistent with Singer’s broader work, but shows that this version carries significant costs. The paper concludes that although we have a moral obligation to help those less …

Privately Owned Companies Dominate Renewable Energy Generation Ownership Around The World, Dyaran Bansraj, Theodor Florian Cojoianu, Xi Hu, Khaladdin Rzayev, Francisco Urzua

Research Collection College of Integrative Studies

Global sustainable finance policies are premised on publicly listed companies driving decarbonization through transparency, investor pressure, and capital market access. Analysing c. 20,000 corporate owners of renewable and fossil-fuel assets worldwide, we show the opposite: private firms own approximately 75% of global renewable generation capacity. This private dominance holds across all major technologies and regions, with listed ownership of renewable assets being the majority only in the oil & gas and technology sectors. The Paris Agreement did not alter this balance. Instead, ownership of the energy transition reflects countries' financial structures, with similar patterns observed across manufacturing, construction, and financial …

Bim-To-Brick: Using Graph Modeling For Iot/Bms And Spatial Semantic Data Interoperability Within Digital Data Models Of Buildings, Filippo Vittori, Fu Chuan Tan, Laura Anna Pisello, Adrian Chong, Cristina Piselli, Clayton Miller

Research Collection College of Integrative Studies

The holistic management of a building requires data from heterogeneous sources such as building management systems (BMS), Internet-of-Things (IoT) sensor networks, and building information models (BIM), all aimed at environmental well-being. Data interoperability is a key component to eliminate silos of information, and using semantic web technologies like the BRICK schema, an effort to standardize semantic descriptions of the physical, logical, and virtual assets in buildings and the relationships between them, is a suitable approach. However, current data integration processes can involve significant manual interventions. This paper presents a methodology to automatically collect, assemble, and integrate information from a building …

Cross-Domain Disaggregation Of Electricity For Heating In All-Electric School Buildings – Learning From School Buildings With District Heating, Synne Krekling Lien, Ada Canaydin, Clayton Miller, Chun Fu, Hussain Kazmi, Jayaprakash Rajasekharan

Research Collection College of Integrative Studies

Electric heating is widespread in Norwegian buildings and significantly contributes to peak loads in the electricity grid. Non-residential buildings are typically heated either by district heating or a combination of electrical heating appliances. Despite its widespread use, most buildings lack sub-meters for electric heating. As a result, the true potential for energy efficiency and load flexibility from heating appliances in buildings remains unknown. Non-intrusive load monitoring and disaggregation techniques offer alternatives to sub-metering by using data-driven methods to extract electricity use for appliances from time-series data. However, little research has been conducted on disaggregating electrical heating loads from low-resolution data, …

The Pluralistic Natural Capital Values Of A Tropical City, Adrienne Gret-Regamey, Et Al.

Research Collection College of Integrative Studies

Nature in cities is essential for human well-being. Quantifying and valuing the goods and services provided by nature to city dwellers is missing in tropical contexts. Yet, as cities worldwide face similar challenges, understanding the services provided by tropical urban ecosystems becomes imperative for effective management. Here, we present the first Natural Capital Assessment of a tropical city, unveiling three critical insights. Firstly, we demonstrate the vital reliance of a developed tropical city on nature, particularly for climate change mitigation through regulating services. Secondly, we identify intact natural areas as Singapore’s most valuable assets, stressing the significance of the quality …

Assessing The Impact Of Maternal Oral Health On The Risk Of Adverse Birth Outcomes, May Amr Salama

Health Services Research Dissertations

Preterm birth (PTB) and low birth weight (LBW) are leading causes of neonatal morbidity and mortality. Maternal periodontal disease (PD) has been increasingly linked to these adverse birth outcomes (ABOs), yet questions about causality and treatment effectiveness persist due to study design heterogeneity and potential unmeasured confounding. These gaps hinder the development of clear clinical and public health guidelines. This dissertation addresses these gaps through three interconnected studies assessing the relationship between maternal oral health and ABOs.

The first study employed a meta-epidemiological analysis of 62 original studies from nine systematic reviews to evaluate the impact of unmeasured confounding on …

Community College Student Parents And Their Experiences With Mindfulness Training, Polly Nesselrodt

Educational Leadership & Workforce Development Theses & Dissertations

Community college students who are parents (student parents) are highly motivated to succeed but face many challenges, including finances, transportation, and childcare, which leads to high levels of stress and anxiety. Mindfulness practices of returning to the breath and staying present in the body have been shown to help people manage stress and anxiety and live with greater ease. Using the stress and coping theory of Lazarus and Folkman (1984) as a theoretical framework, the purpose of this study was to examine the experiences of student parents who participated in mindfulness training. Participants attended mindfulness classes, facilitated by an instructor …

A Systematic Review Of Corporate Ethics Program Training Strategies To Improve Ethical Workplace Cultures, Robin Raye Altice

Educational Leadership & Workforce Development Theses & Dissertations

The demand for corporations to practice more ethically responsible conduct and decision making is growing with every news report of another corporate scandal, lawsuit, fine, or high-visibility C-suite firing. To develop an ethical workplace culture, organizations should implement a comprehensive ethics program that fosters and encourages ethical decision making, especially among current and future leaders. However, there is little research and few guidelines for how ethics program administrators should design corporate ethics training to effectively practice and master the skill of ethical decision-making in efforts to continually grow a more ethical work environment. This study aims to identify corporate ethics …

Schema, Stigma, And The “We-Them” Divide: Perspectives On Ageism From Everyday Life To Healthcare, Temple D. West

English Theses & Dissertations

Ageism remains a pervasive and often underexamined form of discrimination, affecting older adults across both everyday and clinical contexts. This paper explores how cognitive schemas—mental frameworks that shape perception and experience—and stigma interact to reinforce a “we–them” divide between and older patients and healthcare providers, as well as between older and younger individuals in broader society. Through focus groups and listening to the voices of older patients, this study examines how assumptions of age-based decline are embedded in society and inform schemas of ageism. It considers how those schemas shape the spoiled identity of older people as a stigmatized group, …

Unraveling The Links Between Substance Use And Academic Motivation In Higher Education, Melissa Lynn Goins

STEMPS Theses & Dissertations

Self-Determination Theory (SDT) posits that the quality of students’ motivation regulation (i.e., autonomous versus controlled) shapes both learning and health behavior, yet few studies have examined the relations among motivation regulation, alcohol and cannabis use, and achievement. In this study, I surveyed 459 undergraduates at a mid-sized public university in the southeastern United States. Participants completed the Academic Motivation Scale-College version 28 to assess autonomous and controlled motivation regulation, a typical-week alcohol grid, a seven-day cannabis grid, and self-reported grade point average (GPA). Results indicated that autonomous academic motivation was uniquely related to GPA; however, neither motivation variable related to …

Un-Tempering The Tempered Radical: A Phenomenological Study Of Black Female Superintendents In Neoliberal Education Systems, Melanie Fitzgerald Daniel

Educational Leadership & Workforce Development Theses & Dissertations

The persistent and severe underrepresentation of Black women in K-12 educational leadership (just 1.4% of superintendencies) is a critical manifestation of Epistemic Injustice (Fricker, 2007) and the Architecture of Hostility. Dominant managerial paradigms in education structurally suppress the voices and devalue the expertise of Black women, leading to both testimonial injustice (credibility deficits) and hermeneutical injustice (misinterpretation of experience). This context forces them to pursue advancement within systems fundamentally structured to exclude them. This phenomenological study utilizes a nested theoretical framework, comprising Neoliberalism (macro-context), Epistemic Injustice (meso-critique), and Tempered Radicalism (Meyerson & Scully, 1995; Ngunjiri, 2012) (micro-agency), to illuminate the …

In this dissertation, titled “A Voice to Remember: Recovering the Rhetoric of Mordecai Wyatt Johnson,” I perform and analyze the rhetoric associated with him. Johnson was well known for being the president of Howard University; the goal of this project is to recover the rhetoric and identify the common themes. The two themes identified in Johnson’s rhetoric are religion and education. Personal traits and associations with religion are traced …

Identifying Alcohol Intervention-Relevant Constructs For Greek Life: Examining Across Greek Membership And Gender Among College Students, Emily Susan Renzoni

Psychology Theses & Dissertations

Among college populations, students who are members of social Greek life organizations (i.e., social fraternities and sororities) drink more and experience higher rates of negative alcohol-related consequences than their non-affiliated peers. Although there has been success of alcohol interventions in general college populations, research has shown that college drinking interventions that are delivered to students in Greek life are not efficacious in reducing alcohol consumption or related consequences. It is meaningful to investigate if the content commonly addressed in these interventions, although well-documented as being linked to drinking in the general college population, has the same associations for students who …

Exploring The Impact Of Identity-Based Bullying On Suicidal Thoughts And Behaviors Among 6th-12th Grade Youth In Virginia, Camille N. Johnson

Psychology Theses & Dissertations

Suicidal thoughts and behaviors (STBs) are a growing public health concern among youth. Bullying victimization is a robust risk factor for STBs and identity-based bullying (IBB) or bullying that occurs due to a person’s actual or perceived social-identity/identities that is ingrained in discrimination, prejudice, or bias, has been found to be more strongly associated with STBs compared to bullying that was unrelated to identity. The current study used data from the Virginia School Survey of Climate and Working Conditions (N=399,493) to examine associations between general bullying, adult-perpetrated bullying, and IBB with depression and STBs among 6th-12th grade youth. This study …

Reading The Romance Reader: Booktok, Algorithmic Subjugation, And The Fight For Cultural Legitimacy, Emily Maranto Hill

Communication & Theatre Arts Theses

This thesis examines the transformation of romance reader identity through the lens of BookTok, investigating how digital platforms grant cultural legitimacy while simultaneously subjugating community practices to algorithmic control. Romance readers historically developed emotional labor practices, counter-public formation strategies, and fan-driven meaning-making to resist decades of cultural marginalization. Through analysis of TikTok's platform attributes, user behaviors, and the viral Tillie Cole controversy, this study traces how BookTok converts these resistant practices into behavioral data optimized for engagement rather than authentic discourse. The research employs theoretical frameworks including Janice Radway's ethnographic analysis, Shoshana Zuboff's surveillance capitalism, Nick Srnicek's platform capitalism, and …

Proactive Onboarding Services Model As An Academic And Social Integration Strategy For First-Time In College Students At A Virginia Community College, Jhansi V. Eturu

Educational Leadership & Workforce Development Theses & Dissertations

A recent survey by the Education Advisory Board (EAB) found that of the 1000 community college students surveyed, 56% nearly quit before classes started due to challenges during college onboarding. Similarly, admissions data from the Virginia Community Colleges System (VCCS) indicated that more than half of the students who apply do not enroll in classes, highlighting a need to closely examine the onboarding process and support services provided to understand what is effective and what is not. The purpose of this study is to understand the predictive utility of certain student onboarding services, such as an appointment with an admissions …

Policymaker Receptivity To Corporate Political Activity As Influenced By Activists, Mark E. Bateman

School of Public Service Theses & Dissertations

This dissertation considers the role of shareholder resolutions and employee strikes as representations of activist activities targeting corporations and their influence on corporate political activity (CPA). The study builds from the McDonnell and Werner (2016) study in Administrative Science Quarterly, “Blacklisted businesses: Social activists’ challenges and the disruption of corporate political activity” that assessed the role of consumer boycotts vis-à-vis CPA. Starting with the political marketplace framework, introducing the policy relationship framework, and using signal theory, the dissertation found some support that shareholder resolutions and employee strikes related to increases in PAC refunds, that temporal issue salience to the …

Examining The Perceptions Of Economics And Personal Finance Teachers' Preparedness To Teach Financial Literacy, Tasha L. Wearren

Educational Leadership & Workforce Development Theses & Dissertations

Financial literacy has become an important topic in our society. Despite an increased focus in financial literacy education, there is limited research assessing teachers’ ability to teach financial literacy by examining their endorsement area. According to Soroko (2021), research is limited regarding teachers’ beliefs and practices as it relates to financial literacy. As O’Neill and Hensley (2016) indicated, “Teachers cannot teach personal finance well if they do not understand it themselves and/or cannot engage their students” (p. 639). This qualitative multiple case study examined how Economics and Personal Finance teachers perceive their preparedness to teach financial literacy with different endorsements. …

Benzodioxane-Benzamides Targeting Bacterial Cell Division Protein Ftsz Potentially Disrupt Slma-Mediated Nucleoid Occlusion And Reversible Biomolecular Condensation, Marta Sobrinos-Sanguino, Inés Barros-Medina, Lorenzo Suigo, Alessia Lanzini, Ermanno Valoti, William Margolin, Valentina Straniero, Begoña Monterroso, Silvia Zorrilla

Faculty, Staff and Student Publications

New strategies are urgently needed against antimicrobial resistance, a major health threat, and the different mechanisms regulating the bacterial cell division machinery offer multiple opportunities for developing novel therapeutics. FtsZ, an essential protein of this process, is targeted by multiple small molecules, and benzodioxane-benzamides (BDOBs) are among the most potent inhibitors in several bacterial species. BDOBs mechanisms are however poorly understood, particularly their impact on FtsZ's interplay with partners and ability to assemble phase-separated biomolecular condensates potentially involved in stress sensing. We show that certain BDOBs shielded FtsZ against depolymerization induced by the nucleoprotein complexes of SlmA, which inhibit Z-ring …

The study showed significantly improved objective response rate by blinded independent central review, and significantly longer progression-free survival by blinded independent central review and overall survival in patients treated with first-line encorafenib and cetuximab plus mFOLFOX6 compared with chemotherapy with or without bevacizumab. The safety profiles were consistent with those known for each agent. These results led to the approval of encorafenib and cetuximab plus mFOLFOX6 for the …

Tubulin Regulates Stability And Localization Of Stmn2 By Binding Preferentially To Its Soluble Form, Xiang Deng, Gary A Bradshaw, Marian Kalocsay, Timothy Mitchison

Faculty, Staff and Student Publications

The small, tubulin-binding protein STMN2 is highly expressed in neurons and is implicated in amyotrophic lateral sclerosis. STMN2 degrades rapidly and accumulates at axotomy sites, suggesting fast turnover is crucial for its neuroprotective function. We show that STMN2 was primarily degraded by the ubiquitin-proteasome system. Its membrane-targeting N-terminal domain promoted fast turnover, whereas its tubulin-binding domain promoted stabilization. Proximity labeling and imaging showed that tubulin binding reduced STMN2 targeting to trans-Golgi network membranes. Pull-down assays showed that tubulin binds preferentially to soluble over membrane-bound STMN2. Our observations suggest that STMN2 interconverts between a soluble, tubulin-bound form and a membrane-bound, tubulin-free …
