Predicting Thoroughbred Yearling Auction Prices With Machine Learning: Evidence From The Keeneland September Sale, Yanchao Yang, John Clarke, Tapaan Madal '26, Thinh Nguyen '26, Trung Pham '25

Business Analytics Faculty Publications

We apply machine learning methods to predict Thoroughbred yearling auction prices at the Keeneland September Sale (2020–2024). Our sample includes 5,788 yearling prices with pedigree data. We use both linear and tree-based models to predict log prices. We use cross-validation to tune model hyperparameters and select Ridge regression (α = 1.451) as the primary model for interpretation given its stability and interpretability. The Ridge regression explains approximately 54% of out-of-sample variation (R2≈ 0.5403). Sire and Dam Reputation emerge as the dominant predictors. Results provide pricing benchmarks and show how reputation and session structure shape Thoroughbred yearling auction prices.

Dissertations - ALL

Transgender Asian Americans navigate gender identity within complex cultural, familial, and relational contexts shaped by collectivist values, racialized stereotypes, and social stigma. Despite increasing research on transgender experiences, limited scholarship has explored how transgender Asian Americans understand and negotiate their identities within family and intimate relationships. Grounded in Minority Stress Model and intersectionality theory, the current study, adopted strength-based perspectives, aims to understand unique experience related to familial and intimate relationships as well as their supports, and how they manage their relational needs as well as resilience process, shaped by the intersection of transgender identity and racial/ethnic identity. Through semi-structured …

Talking From The Soul: Exploring The Impact Of African American Vernacular English (Aave) In Digital News On Black Youth Political Behavior, Ananda Collins

Dissertations - ALL

Black youth have a long history of political engagement yet consistently report the lowest levels of traditional forms of political participation in the entire U.S electorate. While social media has emerged as an alternative political space, structural and linguistic barriers continue to limit their engagement. This dissertation examines whether African American Vernacular English (AAVE) in digital political news media influences the political behavior of young Black Americans. Using a mixed-methods approach that combines a survey experiment and in-depth interviews, this study tests whether political news written in AAVE, compared to Standard American English (SAE), affects political engagement, information retention, and …

Faculty, Staff and Students Publications

Growth/differentiation factor-15 (GDF15) is a secreted cytokine strongly associated with dementia risk. However, the extent to which GDF15 represents a biomarker and driver of dementia risk remains unclear. Across multiple cohorts, we demonstrated that plasma GDF15 is associated with greater dementia risk over 15- to 25-year follow-up periods when measured in midlife, with stronger associations observed for vascular, compared to Alzheimer's disease (AD), dementia. Two-sample Mendelian randomization supported plasma GDF15's mechanistic role in AD and related dementias, while cohort studies linked it to cerebral small vessel disease, neurodegeneration, phosphorylated tau, and a cerebrospinal fluid proteomic signature indicative of neuroimmune activation. …

Feed-Ing Identity Item Development, Observational, And Experimental Analysis To Study The Relationship Between Algorithm-Based Short Video Platforms And Identity, Sarah Elizabeth Hogenboom-Jones

Dissertations - ALL

Short video social media platforms (SVPs) such as TikTok and YouTube Shorts are distinguished from other forms of social media by two key features: video delivery and explicit algorithm-driven selection. In this project, I argue that these platform features make SVPs particularly potent at reinforcing individuals’ identities and enable more effective persuasion relative to other media. These media are sufficiently unique that to study their effects I develop novel survey items designed specifically around the key features of SVPs. These items assess both usage of SVPs and their impact on identity. I find that users of SVPs are particularly likely …

Peptide And Peptide Bioconjugate Based Drug Development For The Treatment Of Metabolic Diseases, Nancy Cham

Dissertations - ALL

The Doyle group has coined the term ‘corrination’ to describe the conjugate modification of a peptide, protein, small molecule, or radionuclide with a corrin ring-containing molecule such as cobalamin, also known as vitamin B12 (B12), or cobinamides. By exploiting the innate chemico-physical properties of corrin ring-containing compounds, both in general and specifically via the innate dietary B12 uptake pathway in mammals, corrination has been explored for drug development and targeted/localized delivery of probes and therapeutics. Most recently, it is in the field of peptide-based therapeutics that corrination is generating significant interest, no doubt driven in part by the recent successes …

Marble Bodies: Sculpture, Gender, Race, And Nineteenth-Century U.S. Literature, Madeline Olley

Dissertations - ALL

Marble Bodies reads across both literary texts and sculptures to ask how sculptural logic operates across forms to reveal what sculptors and sculpture offer the field of nineteenth-century U.S. literary studies—formally, theoretically, and methodologically. It argues that sculpture functions not merely as subject matter within nineteenth-century American literature but as an interpretive framework that reveals how bodies are objectified, valued, and assigned cultural meaning. With attention to the formal and material properties of sculpture—stillness, smoothness, and duration—and to the questions of ideality, valuation, and preservation that sculpture generates, this dissertation shows how nineteenth-century writers and artists found in those properties …

Aging Alone In Malaysia: Social Challenges And Legal Protections, Jal Zabdi Mohd Yusoff, Zulazhar Tahir, Siti Zaharah Jamaluddin

Hasanuddin Law Review

According to The Japan Times, nearly 28,000 elderly individuals in Japan will die alone in the first half of 2024. This alarming trend is not unique to Japan; many countries, including Malaysia, are facing the challenges of an aging population. As Malaysia approaches becoming an aging nation, issues affecting the elderly, particularly those living alone, demand urgent attention. While not all elderly people face the same circumstances, some enjoy stable finances or live with their family, while others live in isolation due to various factors, such as remaining unmarried, widowhood, or estranged familial ties. Some are simply separated by their …

Weighted Average Ensemble Learning Model For Improving Brain Tumor Classification, Laith H. Alhasnawy, Hasanain Ali Al Essa, Tahseen A. Wotaifi, Abbas F. Hommadi, Ameer K. Al-Mashanji

Baghdad Science Journal

The detection of Brain Tumors (BTs) is of great benefit in identifying the growth of dangerous cells in the brain that pose a threat to the patient's life. Early detection of BTs remains a significant challenge due to subtle differences among tumor types and the complexity of brain anatomy. Manual diagnosis by radiologists is often time-consuming and subject to variations, which may delay treatment. Among available imaging techniques, Magnetic Resonance Imaging (MRI) is widely used because of its high-resolution capabilities. Deep Learning (DL) has achieved remarkable success in image classification tasks through Transfer Learning (TL), which utilizes pre-trained models. Therefore, …

Predictive Mobility-Aware Analysis Of Controller Overhead In Sdn-Enabled Iot, Abdulrahman Saidu, Kamalrulnizam Bin Abu Bakar, Babangida Isyaku, Muhammad Nura Yusuf, Farkhana Binti Muchtar

Baghdad Science Journal

The rapid growth and increasing mobility of Internet of Things (IoT) mobile devices significantly intensify flow setup requests in Software-Defined Networking (SDN). Frequent movement of mobile devices across access points triggers repeated flow rule installations in data-plane switches, leading to excessive controller overhead under limited flow-table memory capacity. Inaccurate mobility prediction in existing approaches further aggravates this challenge by causing unnecessary rule placement and redundant flow setup requests. This study investigates the impact of mobility-aware prediction on controller overhead with experimental scenarios using different groups of mobile IoT devices, while considering controller CPU and memory utilization. A proactive mobility prediction …

U.S. Service Member To Counseling Student, Nicole Marie Arcuri-Sanders, Kellie Forziat-Pytel

Educational Sciences and Organizations

This qualitative descriptive study examines the absence of military career pathways for licensed mental health counselors (MHCs) and the impact of this structural limitation on service members' career transitions. Findings indicate that both combat and non-combat veterans pursued mental health counseling due to personal service-related mental health experiences and dissatisfaction with available care while in service. Despite these challenges, many participants expressed a strong desire to continue serving their country as professional counselors. Over half of the participants reported separating from the military because no occupational role existed for licensed MHCs. At the same time, most indicated they would have …

Seeing Is Believing: Mental Imagery Amplifies Moral, Emotional, And Motivational Responding To Mentally Constructed Hypothetical Events, Julie L. Ji, Adam S. Radomsky, Jackie Andrade

School of Psychology

Mental imagery is theorised to support important mental simulation processes, yet there remains little direct evidence of its functional impact on affective, moral, and motivation outcomes. This study examined whether the ability to generate visual mental imagery amplifies “as-if-real” responding to a mentally constructed harm event. Using a modified laboratory harm provocation paradigm, Aphantasics (individuals with no or minimal visual imagery; N = 32) and Visualisers (those with normal to high imagery ability; N = 48) were asked to write down the sentence “I hope [name of a loved one] is in a car accident”, followed by instructed mental simulation …

Rethinking African Security In The Anthropocene: An Alternative Framework, Hamdy A. Hassan

All Works

Introduction – Traditional approaches to African security often treat neocolonialism, governance failures, and terrorism as isolated issues, obscuring their systemic interconnections under Anthropocene conditions of human-induced environmental change. This study argues that African security should be reconceptualized in light of climate change, resource depletion, and ecosystem degradation, as these dynamics reshape the continent's collective security arrangements. Methods – This research combines critical analysis of African collective security mechanisms, focusing on the African Union and the African Peace and Security Architecture, with qualitative evidence from 15 unstructured interviews conducted in Mali, Nigeria, and Egypt between July and October 2025. Thematic qualitative …

Binding Energy Of Muonic Beryllium: Perturbative Versus All-Order Calculations, Shikha Rathi, Ulrich D. Jentschura, Paul Indelicato, Ben Ohayon

Physics Faculty Research & Creative Works

We compute the ground-state binding energy of muonic (Formula presented) (Formula presented) Be in two ways: first, the fully perturbative treatment of the nuclear-size effect often employed in light systems, and second, an approach that accounts for the finite-nuclear-size to all orders (and is inspired by calculations otherwise employed for heavy muonic ions). The results are compared term by term and show that both approaches agree to better than one part-per-million of the total energy. The objective of this work is twofold. The first is practical: to provide a parameterization that allows the extraction of the (Formula presented) (Formula presented) …

Interpreting Discrepant Multi-Informant Data: Examining School Psychologists’ Decision-Making Processes With Social-Emotional And Behavioral Assessment, Thomas Koza

USF Tampa Graduate Theses and Dissertations

Multi-informant assessment is a common method used by school psychologists to collect data on students' social-emotional and behavioral concerns across the three tiers of the Multi-Tiered System of Supports (MTSS) framework. While this data can provide a comprehensive understanding of student functioning, informant discrepancies are common, and little is known about how school psychologists make sense of discrepant data or whether using structured frameworks can support their interpretation. This dissertation used an experimental mixed-methods design with vignettes to examine how school psychologists interpret discrepant multi-informant social-emotional and behavioral assessment data and whether exposure to a structured framework influenced this process. …

Department of Teaching and Learning Scholarship and Creative Works

The intention guiding the design of this study was to amplify and listen to children's voices in early years research. The aim of this qualitative research meta-synthesis was to engage in new analyses and interpretations about mindfulness through the lens of young children. Our research question emerged as a result of a gap in the literature about the importance of young children as the experts in their own lives, and the absence of a collective understanding about their first-hand perspectives about mindfulness practices in school. We critically examined findings from eight studies using a distinct seven-stage qualitative research meta-synthesis process, …

Demonstration Of 23-Gene Expression Profile Test Utility Within Prame Immunohistochemistry Results: A Case Series, Gregory A. Hosler, Matthew S. Goldberg, Etan Marks

GME Publications

Histopathological examination using hematoxylin and eosin (H&E)-stained tissue is sufficient for diagnosing most melanocytic neoplasms as benign or malignant; however, diagnostic tools such as PRAME (preferentially expressed antigen in melanoma) immunohistochemistry (IHC) and the 23-gene expression profile (23-GEP) test can aid in the analysis of histopathologically ambiguous lesions, which can be referred to as diagnostically challenging, equivocal, indeterminate, or uncertain. When compared with the gold standard of H&E diagnosis by a dermatopathologist, PRAME IHC showed 83.2% sensitivity and 99.3% specificity in an initial validation cohort and 23-GEP showed 91.5% sensitivity and 92.7% specificity in an independent validation cohort. In addition, …

Pre-Freudian Recurrence: Photography And The Trace Before The Uncanny, Iwan Zahar, Karna Mustaqim, Salman Maulana, Irma Damayantie, Tri Wahyudi

Bahasa dan Seni: Jurnal Bahasa, Sastra, Seni, dan Pengajarannya

This practice-led research proposes recurrence as a systematic photographic method, where Derrida's concept of iterability is achieved through controlled visual iteration. Through recurrence, identical objects undergo transformation across iterations because variations in light, motion and environmental conditions produce perceptual instability rather than visual sameness. This process produces uncanny effects identifiable through perceptual ambiguity (Jentsch), environmental transformation and reappearance of overlooked materials (Schelling). The work engages pre-Freudian concepts of the uncanny - Jentsch's intellectual uncertainty and Schelling's definition of the uncanny as ``something that should have remained hidden but has returned to light.'' Waste materials, typically ignored or excluded from conscious …

The Correlation Between Left Ventricular Filling Pressure And Fluid Responsiveness In Patients With Acute Heart Failure With Reduced Ejection Fraction, Ratna Mariana Tamba, Andika Sitepu, Hilfan Ade Putra Lubis, Abdul Halim Raynaldo, Cut Aryfa Andra, Andre Pasha Ketaren, Yuke Sarastri

Journal of the Hong Kong College of Cardiology

Background: Fluid responsiveness describes the capacity of the myocardium to raise stroke volume by at least 10% when ventricular filling is increased, consistent with the principle outlined by Frank and Starling. In patients with acute heart failure with reduced ejection fraction (HFrEF), elevated left ventricular filling pressure (LVFP) and impaired contractility frequently place the ventricle on the flattened segment of this relationship, resulting in a limited response to preload changes. Objectives: To investigate the relationship between LVFP and fluid responsiveness in patients with acute HFrEF. Methods: This study aimed to explore the link between LVFP and fluid responsiveness using echocardiography …

Application Of Ai Risk Prediction Tools For Cardiovascular Care In Hong Kong: A Systematic Review With Insights From Clinicians, Celine Sze Ling Chui, Celia Jiaxi Lin, Ruibang Luo, Yekai Zhou, Nadeem Qureshi, Li Wah Tam, Carmen Chan, Ian Chi Kei Wong, Kai Hang Yiu, P-Cardiac Consortium

Journal of the Hong Kong College of Cardiology

Background: Cardiovascular diseases (CVD) present a substantial burden on global and local healthcare systems, particularly within Hong Kong's overstretched public secondary care settings coupled with an aging population. The Personalized CARdiovascular DIsease risk Assessment for Chinese (P-CARDIAC), a locally developed and validated artificial intelligence (AI) powered cardiovascular risk assessment tool, offers a transformative opportunity for enhancing care through systematic risk prediction and a multidisciplinary care approach. Implementation strategies for its application in secondary care remain undefined. Methods: We gathered local insights from one expert meeting and thirteen semi-structured interviews with cardiologists and pharmacists, matched these with barriers and respective facilitators …
