Essays In Empirical Asset Pricing, Jiaen Li

Olin Business School Graduate Student Theses and Dissertations

My dissertation explores two broad questions. First, what is the role of intangible forces like ideological narratives in belief formation and asset prices? Second, how can we understand the systematic components in asset pricing? In Chapter 1, using cryptocurrencies as a laboratory, I examine the role of ideological narratives in asset prices—an area remains underexplored. Leveraging social media data and large language models to measure ideology dynamics, I find that fluctuations in two ideological narratives—anarchism and decentralization—are priced in the cross-section of cryptocurrency returns. Consistent with the view that factors proxy for state variables, ideology factors contain distinct information about …

Behavioral Decision-Making In Platform Operations, Nicholas Clyde

Olin Business School Graduate Student Theses and Dissertations

Over the past decade, online platforms have experienced significant growth, both in terms of user interest and the range of services they offer. These platforms now provide a wide array of services, from groceries (e.g., Instacart) and transportation (e.g., Uber, Lyft) to entertainment (e.g., TikTok, Twitch). Understanding how individuals interact with these platforms is crucial, not only for the platforms’ success but also for assessing their broader societal impact. In my research, I employ a range of empirical methods—including field experiments, natural experiments, and online experiments—to explore how online platforms can intentionally and unintentionally influence behaviors." In Chapter 1, “The …

Leveraging Ai For Marketing Decisions: Algorithmic Targeting And Healthcare Applications, Annie Shi

Olin Business School Graduate Student Theses and Dissertations

In this dissertation, I leverage artificial intelligence (AI) for making effective marketing decisions, specifically on how to measure the causal effects of targeting promotions and detecting suspicious retail buyers of opioids. In the first chapter, we propose a novel approach in measuring the true causal effects of targeting promotions. Targeting promotions on online platforms are often determined by AI algorithms, which utilize extensive customer and seller information to generate various algorithmic scores for targeting. Effective targeting, however, will lead to selection bias when evaluating the causal effects of promotions. we analyzed 2,294 promotion experiments on a major online retail platform …

Essays In Supply Behavior In Sharing Economy, Chong Bo Wang

Olin Business School Graduate Student Theses and Dissertations

My dissertation investigates supply behavior within the sharing economy, focusing specifically on the ride-sharing market. Leveraging quantitative methods such as structural modeling, field experiments, and lab experiments, I examine supplier behaviors to help platforms design more effective incentives—including subsidies and strategically framed rewards—to better match supply with demand. In Chapter 1, “Using Field Experiments to Infer Cross-Side Network Effects in the Ride-Sharing Market: How Does Driver Supply Impact Rider Orders, Cancellations, and Customer Lifetime Value?”, I address the central question of how shifts in driver supply affect rider behavior. Collaborating with a leading ride-sharing platform, I implement a natural field …

Assessing The Influence Of Core Transformational Leadership Style On Job Satisfaction And Organizational Citizenship Behavior In A Rural Healthcare Facility, Bruce Daryl Mitchell

Walden Dissertations and Doctoral Studies

The successful application of core transformational leadership (CTL) in healthcare may enhance the quality of patient care and foster a positive and optimistic workforce. As such, CTL may be linked with job satisfaction (JS) and organizational citizenship behavior (OCB). There was a knowledge gap in understanding CTL’s relation to JS and OCB. In this quantitative study, the influence of the predictor variable CTL on the dependent variables JS and OCB was examined. Maslow’s hierarchy of needs provided a theoretical lens for the investigation. The secondary data set included data from 221 participants: 37 physicians, 111 nurses, and 73 other workforce …

The Relationship Between Adverse Childhood Experiences And Posttraumatic Symptomology In Rio Grande Valley Hispanic Adults, Timothy Hollinger

Walden Dissertations and Doctoral Studies

Childhood adversity is a known predictor of poor psychological outcomes in adulthood, yet little is known about this relationship among Hispanic adults in South Texas. This study examined whether adverse childhood experiences (ACEs) are associated with posttraumatic stress disorder (PTSD) symptoms and whether gender, marital status, or educational attainment moderate this relationship. The central research questions were: (1) What is the relationship between ACEs and PTSD symptoms among Hispanic adults in South Texas? and (2) Do gender, marital status, or education moderate this relationship? Guided by Bronfenbrenner’s ecological systems theory, this quantitative archival study used a non-experimental, correlational design. Linear …

Workplace Mobbing, Job Satisfaction, And Intent To Leave The Information Technology Industry, Sherry Elaine Baker-Thompson

Walden Dissertations and Doctoral Studies

Some information technology leaders are increasingly concerned about employees’ intent to leave their organizations, as it contributes to higher turnover rates, increased recruitment costs, and potential disruptions to project continuity and service delivery. Grounded in affective events theory, the purpose of this quantitative correlational study was to examine the relationship between workplace mobbing, job satisfaction, and the intent to leave the information technology industry. The study surveyed 101 information technology employees residing in the United States who had experienced workplace mobbing. The participants completed the Negative Acts Questionnaire, the Job Satisfaction Questionnaire, and the Turnover Intention Questionnaire. Results from a …

Clinical Practice Guideline For Wound Care Management In Primary Healthcare Settings Across The British Virgin Islands To Minimize Clinical Practice Variations, Trorisia Shanika John

Walden Dissertations and Doctoral Studies

This quality improvement (QI) initiative in a British Virgin Islands (BVI) primary healthcare setting involved the problem of inconsistent wound care management among registered nurses, which was a concern that was identified in a 2023 audit. The BVI Health Service Authority (HSA)’s diverse nursing staff, which is recruited across the Caribbean, contributed to varied wound care approaches, negatively impacting healthcare delivery and quality. These inconsistencies led to unequal resource access, increased infection and complication risks, and potential financial and legal liabilities. Furthermore, it could negatively affect staff and patient perceptions, potentially decreasing patient satisfaction, highlighting the urgent need for standardized …

Skin Cancer Diagnosis Utilizing Hybrid Discrete Cosine Transform And High-Performance Convolutional Neural Networks, Mohammed M. Abo-Zahhad, Mohammed Abo-Zahhad

Mansoura Engineering Journal

Detecting skin cancer early and accurately is crucial for successfully treating this potentially fatal disease. Enhancing the accuracy of visual inspection techniques is often necessary to improve clinical decision-making and increase the chance of successful treatment outcomes. In this research, high-performance deep learning (DL) models for automated skin cancer categorization and early skin cancer diagnosis screening are developed and evaluated in conjunction with the discrete cosine transform (DCT). For this purpose, features are extracted from medical images using both techniques. The DCT is used for feature extraction and dimensionality reduction, while deep learning (DL) trains fully connected models for classification …

Exploring Differences Between Mothers’ And Fathers’ Language Attitudes In Multilingual London, Anna Caunt, Caroline Floccia, Rana Abu-Zhaya

School of Psychology

This study investigated the language attitudes of parents raising multilingual infants in London. Using a newly developed questionnaire, 131 mothers and fathers rated their attitudes towards their languages across three themes: (1) their emotional resonance with the language, (2) the significance of the language in their personal life, and (3) its importance in bringing up a multilingual child. Parents varied in the combination of languages they reported speaking, and English, the society language, was either parents’ L1, L2 or L3. Our results showed that both mothers and fathers had similarly positive attitudes towards English, but differed in their attitudes towards …

Poetries Of Abandonment: A Study Of Plath And Glück, Yara Abdelmoneim

Theses and Dissertations

This thesis explores the intersection between literature and trauma, which can be discerned in the key works of two poets, Sylvia Plath and Louise Glück. While offering readings of crucial poems, the thesis also examines the interrelations among trauma, memory and narrative as theorized by two contemporary psychiatrists, Bessel van der Kolk and Judith Herman. Both Plath and Glück wrote about personal and generational trauma after going through different experiences of abandonment. Absence, indirection and repetition provide the basis for literary techniques that allow their traumas to be better understood by authors and readers alike. The degree to which each …

Predicting Seizure Onset Zones From Interictal Intracranial Eeg Using Functional Connectivity And Machine Learning, Jared Pilet, Scott A. Beardsley, Chad Carlson, Christopher T. Anderson, Candida Ustine, Sean Lew, Wade Mueller, Manoj Raghavan

Biomedical Engineering Faculty Research and Publications

Functional connectivity (FC) analyses of intracranial EEG (iEEG) signals can potentially improve the mapping of epileptic networks in drug-resistant focal epilepsy. However, it remains unclear whether FC-based metrics provide additional value beyond established epilepsy biomarkers such as epileptic spikes and high-frequency oscillations (HFOs). Using interictal iEEG data from 26 patients, we estimated FC across eight frequency bands (4–290 Hz) using amplitude envelope correlation (AEC) and phase locking value (PLV). From the resulting FC-matrices, we estimated two graph metrics each to derive 32 FC-based features. We also extracted features related to spikes, HFOs, and power spectral densities (PSD). A trained support …

A Cross-Sectional Study Of The Role Of Epithelial Cell Injury In Kidney Transplant Outcomes, Philip F. Halloran, Tarek Alhamad, Et Al.

2020-Current year OA Pubs

BACKGROUND: Expression of acute kidney injury-associated (AKI-associated) transcripts in kidney transplants may reflect recent injury and accumulation of epithelial cells in "failed repair" states. We hypothesized that the phenomenon of failed repair could be associated with deterioration and failure in kidney transplants.

METHODS: We defined injury-induced transcriptome states in 4,502 kidney transplant biopsies injury-induced gene sets and classifiers previously developed in transplants.

RESULTS: In principal component analysis (PCA), PC1 correlated with both acute and chronic kidney injury and related inflammation and PC2 with time posttransplant. Positive PC3 was a dimension that correlated with epithelial remodeling pathways and anticorrelated with inflammation. …

Subcortical Correlates Of Consciousness With Human Single Neuron Recordings, Michael Pereira, Nathan Faivre, Fosco Bernasconi, Nicholas Brandmeir, Jacob E Suffridge, Kaylee Tran, Shuo Wang, Victor Finomore, Peter Konrad, Ali Rezai, Olaf Blanke

2020-Current year OA Pubs

Subcortical brain structures such as the subthalamic nucleus or the thalamus are involved in regulating motor and cognitive behavior. However, their contribution to perceptual consciousness remains unclear, due to the inherent difficulties of recording subcortical neuronal activity in humans. Here, we asked neurological patients undergoing surgery for deep brain stimulation to detect weak vibrotactile stimuli applied on their hand while recording single neuron activity from the tip of a microelectrode. We isolated putative single neurons in the subthalamic nucleus and thalamus. A significant proportion of neurons modulated their activity while participants were expecting a stimulus. We found that the firing …

The Joint Association Of Diet Quality And Sleep Regularity With Incident Cardiovascular Disease In The Multi-Ethnic Study Of Atherosclerosis, Kaitlin S Potts, Claire Veldkamp, Alexis C Wood, Erin D Michos, Raymond Noordam, Tianyi Huang, Susan Redline, Heming Wang

Children’s Nutrition Research Center Staff Publications

Background/objectives: Diet quality and sleep regularity both influence cardiovascular disease (CVD) risk and may influence each other, but there is scarce evidence for their joint or interacting associations in relation to CVD. We assessed these associations in the Multi-Ethnic Study of Atherosclerosis (MESA).

Methods: Participants free of CVD with valid diet and sleep measures in 2010-2013 were included and followed through 2020 for detection of incident CVD (188 events detected over 8.8 years among 1782 participants; 55% women). Sleep timing and duration regularity were assessed via the intra-individual SD of sleep onset time and duration across 5- to 7-day actigraphy. …

The Perk/Atf4 Pathway Is Required For Metabolic Reprogramming And Progressive Lung Fibrosis, Jyotsana Pandey, Jennifer L Larson-Casey, Mallikarjun H Patil, Chao He, Nisarat Pinthong, A Brent Carter

Faculty, Staff and Students Publications

Asbestosis is a prototypical type of fibrosis that is progressive and does not resolve. ER stress is increased in multiple cell types that contribute to fibrosis; however, the mechanism(s) by which ER stress in lung macrophages contributes to fibrosis is poorly understood. Here, we show that ER stress resulted in protein kinase RNA-like ER kinase (PERK; Eif2ak3) activation in humans with asbestosis. Similar results were seen in asbestos-injured mice. Mice harboring a conditional deletion of Eif2ak3 were protected from fibrosis. Lung macrophages from asbestosis individuals had evidence of metabolic reprogramming to fatty acid oxidation (FAO). Eif2ak3fl/fl mice had increased oxygen …

It Is Not Clear How Well Physical Activity Promotion Materials Are Understood: Findings From A Rapid Literature Review, Jafra D. Thomas, Jasmine C. Wong, Regina F. Hockert, Yi Sheng Wu, Winston Kennedy

Topics in Exercise Science and Kinesiology

Topics in Exercise Science and Kinesiology Volume 6: Issue 1, Article 6, 2025. Efforts to promote physical activity and other health-related behaviors are more effective when resource materials are understood by a wide and diverse audience. Before our lab’s previous investigations (Thomas et al., 2024), only one study seemed to use the cloze procedure to directly test the comprehension (i.e., readability) of physical activity promotion material (Cardinal & Seidler, 1995). Thus, this rapid literature review sought to (a) determine the extent the cloze procedure has been used to study physical activity promotion material comprehension in lay adults and (b) collate …

[2025 Honorable Mention] Ice: Trauma, And The War On Immigrant Families, Brittney M. Williams

Ethnic Studies Research Paper Award

This paper exposes how immigration enforcement under the Trump administration’s second term has crossed the line from policy to persecution. ICE is operating like a secret police force, using fear tactics and legal loopholes to tear families apart without cause or due process. The impact is not theoretical. It is real, measurable, and devastating. Children are being taken from schools. Parents are disappearing without explanation. Communities are being pushed into silence and survival mode. This paper focuses on the trauma being inflicted, especially on immigrant youth, and the way outdated laws like the Alien Enemies Act are being twisted to …
