Early Detection Of Alzheimer's Disease And Related Dementias From Spontaneous Speech Using Foundation Speech And Language Models: Comparative Evaluation, Jingyu Li, Lingchao Mao, Xi Mao, Hairong Wang, Zhendong Wang, Xuelei Sherry Ni

School of Economics and Finance Faculty Publications

Background: Alzheimer's disease and related dementias (ADRD) are progressive neurodegenerative conditions where early detection is critical for timely intervention and care planning. However, current diagnostic methods are often inaccessible, costly, and delayed, especially for underserved populations. There is a growing need for scalable, noninvasive tools that can support timely diagnosis. Spontaneous speech contains rich acoustic and linguistic markers that can serve as noninvasive behavioral markers for cognitive decline. Foundation models, pretrained on large-scale audio or text data, generate high-dimensional embeddings that encode rich contextual and acoustic information.

Objective: This study benchmarks open-source foundation language and speech models to evaluate their …

Dissociation Between Physical Reasoning And Tool Use In Individuals With Left Hemisphere Brain Damage, Shuchen Liu, Seda Karakose-Akbiyik, Alfonso Caramazza, Filipa Dourado Sotero, Laurel J. Buxbaum, Aaron L. Wong

Moss-Magee Rehabilitation Papers

Tool use and physical reasoning are often assumed to rely on shared cognitive and neural mechanisms. At some level, this correspondence is expected: using an object typically requires understanding its physical properties. However, both capacities are complex and multicomponential, so the relationship between them may vary across levels of representation and task demands. Here, we asked whether third-person physical reasoning about object dynamics can dissociate from tool use (i.e., performing a tool's typical action) in individuals with left-hemisphere stroke. We tested 11 patients, five of whom showed impairments in tool use. Physical reasoning was assessed using a novel collection of …

Simultaneous Multielectrode Recordings Along The Human Scala Tympani: Evidence For Level-Dependent Place Coding, Amit Walia, Matthew A Shew, Shannon M Lefler, Amanda J Ortmann, Patrick Ioerger, Jordan Varghese, Jacques A Herzog, Craig A Buchman

2020-Current year OA Pubs

The cochlea systematically encodes sound frequency and intensity via a precisely organized tonotopic map, in which traveling waves peak at specific cochlear locations. A fundamental but incompletely understood aspect of auditory coding involves how stimulus intensity shapes this tonotopic organization. In animal models, increasing intensity shifts the cochlear traveling wave peak basally; however, physiological evidence for such intensity-dependent shifts in human cochlear processing is limited. Here, we performed simultaneous multielectrode electrocochleography recordings along the human scala tympani to characterize how cochlear place coding varies as a function of stimulus intensity. In subjects with preserved cochlear mechanics, including individuals with auditory …

Cardeza Foundation for Hematologic Research

Intravital imaging studies have provided insights into the spatial and temporal variations of platelet activation and thrombin generation that occur during hemostasis; however, these studies are generally limited to small vessels due to the practical limitations of imaging in thicker tissues. Recent advances in cleared tissue fluorescence imaging as well as volume electron microscopy (vEM) coupled with machine learning-based image segmentation provide an opportunity for analysis of the 3-dimensional structure of complex tissues. We utilized these technologies to examine hemostatic plugs from murine jugular veins and carotid arteries to investigate the spatial distribution of platelet activation and biochemical responses in …

Faculty, Staff and Student Publications

Background: Children undergoing cancer treatment experience a range of treatment-related toxicities that significantly affect quality of life and adherence to therapy. Current methods for symptom reporting rely heavily on clinician interpretation of caregiver or child verbal reports, which can result in incomplete or inaccurate records. The Pediatric Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (Pediatric PRO-CTCAE; National Cancer Institute) provides a validated mechanism for direct symptom reporting by children and caregivers, yet its traditional administration and preselection of questions limit the breadth of symptom capture.

Objective: This research aimed to co-design and conduct formative usability testing …

The mental health impacts of sex trafficking on Native American survivors and pathways to resilience are important to understanding healing. Native Americans are disproportionately affected by sex trafficking due to systemic inequities, historical trauma, and socioeconomic vulnerability. Using interviews with 47 Native survivors conducted as part of a larger Office on Violence Against Women project, this study analyzes the mental health challenges and recovery strategies identified by participants. Findings reveal that survivors commonly experience significant psychological effects, including post-traumatic stress disorder (PTSD), depression, and anxiety. Among participants, PTSD emerged as the most frequently reported condition, followed by depression and anxiety, …

Care, Control, And The Racial Regulation Of Black Women’S Reproduction In American Medicine, Rheya K. Wilk

Honors Thesis

Black women in the United States continue to experience disproportionately high rates of maternal mortality, negative reproductive healthcare experiences, and documented disparities in medical treatment. From slavery through the twenty-first century, American medicine has repeatedly positioned Black women’s reproduction as a site of regulation, rather than care, making medical mistrust among Black women a rational response to a long history of institutional conflict embedded in American medicine. Drawing on medical history and bioethical analysis, this thesis traces reproductive abuse across distinct, yet connected, eras. Beginning with antebellum gynecological experimentation on enslaved women, it demonstrates how racialized assumptions about pain and …

Exploring The Neural Correlates Of Motor Learning, Brooklyn R. Thomas

Honors Thesis

The left anterior supramarginal gyrus (aSMG) is recognized as a fundamental cortical region involved in the mastery of skilled tool-use. Although various research studies have revealed that anodal transcranial Direct Current Stimulation (atDCS) over the cortex has the potential to boost manual dexterity, the impact of stimulating the aSMG is less understood in relation to the learning process. Within this study, there was a chopstick-based marble task to discover if atDCS applied to the left aSMG was capable of facilitating the acquisition of a novel motor skill. Concurrent electroencephalography (EEG) was used to measure the changes in neural synchrony within …

Honors Theses

Quantifying Black Carbon Concentrations in Georgia and Analyzing Associated Public Health Risks

One of the most daunting challenges of the industrial world is air pollution. Within this broad spectrum, there is an inhalable particle group named PM2.5, which contains black carbon. Black carbon has evidence that supports the generation and worsening of adverse health impacts, which may include birth complications, cognitive deficits in children, pulmonary aggravation, asthma, cardiovascular issues, neurological degenerative patterns, and cancer risk. This is especially seen in vulnerable populations, like children, elderly, and those who already suffer from weakened health, many of which reside in the southern …

The Legacy Of Lead: Lead Exposure's Harmful Effects And Its Concentration In Poc Communities, Layla Sophronia Barber

Student Theses 2015-Present

This thesis examines the disproportionate burden of lead exposure carried by low income, POC communities. The systemic nature of this problem is a symptom of a longstanding legacy of environmental injustice in the United States. Decades of federal neglect are reflected in the higher statistics of lead exposure and poisoning in predominantly black communities. While it is understood that lead exposure poses a serious threat to physical health and early cognitive development, there is a discouraging lack of urgency to remove the toxin from non-wealthy communities. The material covered by this thesis aims to identify and correct the discriminatory social …

Modeling Individual Self-Protective Behavior During Epidemics, Geonsik Yu, Michael J. Garee, Mario Ventresca, Yuehwern Yih

Faculty Publications

Protecting public health from infectious diseases requires collective action, as individual behaviors—such as vaccination and mask-wearing—directly influence disease dynamics. During the COVID-19 pandemic, unexpected public responses often undermined the effectiveness of interventions, highlighting the need to understand collective behavioral patterns and motivations to design more effective mitigation strategies. This study presents an agent-based simulation model that captures how individuals adjust self-protective behaviors based on evolving opinions about disease risk and examines how these decisions interact with external factors, such as public health interventions, to shape collective outcomes. To improve the representativeness of the simulated population, multiple datasets were integrated to …

Inflammatory Markers In The Emergency Department And Ptsd Symptoms In The Aurora Study: A Longitudinal Cohort Study, Kristen Nishimi, Stacey L House, Et Al.

2020-Current year OA Pubs

BACKGROUND: Systemic inflammation is hypothesized to contribute to post-traumatic stress disorder (PTSD) vulnerability. Few studies have examined inflammation shortly after trauma as a predictor of later PTSD symptoms. We examined whether inflammation from the emergency department (ED) post-trauma is associated with PTSD symptom severity over the following 6 months.

METHODS: Our sample included 742 AURORA participants, a longitudinal cohort of patients in 29 EDs across the United States after a traumatic stressor, followed up to 6 months. Plasma cytokines were assessed from a study blood draw in the ED: an inflammatory index (standardized sum of generally pro-inflammatory markers interleukin [IL]-6, …

Hyposense: Multimodal Physiologic And Voc Wearable For Early Hypoglycemia Detection, Nidhi R. Patel

Honors Theses

Hypoglycemia remains a significant safety concern for insulin-dependent individuals, especially when blood glucose declines rapidly during exercise, sleep, or periods of impaired hypoglycemia awareness. Current continuous glucose monitors and automated insulin delivery systems have helped to improve diabetes management, but these technologies primarily respond to glucose trends after they have already started and may not actually provide sufficient warning before symptoms occur. This thesis describes the development of HypoSense, a noninvasive wrist worn wearable concept that is designed to support earlier hypoglycemia risk detection through multimodal physiologic and volatile organic compound emission sensing. HypoSense combines volatile organic compounds/gas sensing with …

BACKGROUND: T-cell redirecting therapies, including T-cell engagers (TCEs) and Chimeric Antigen Receptor T-cell (CAR-T), are under investigation in metastatic castration-resistant prostate cancer (mCRPC). Despite their promising therapeutic potential, these therapies remain in early stages of development due to treatment-related adverse events (TRAEs). This study aims to quantify the frequency and severity of adverse events in clinical trials with a pooled analysis.

MATERIALS AND METHODS: A systematic search of PubMed, CINHAL, Scopus, and Ovid was conducted to identify clinical trials evaluating TCEs or CAR-T in patients with mCRPC. Types and frequencies of TRAEs were collected and analyzed using a random-effects model. …

Lifestyle And Activity Patterns Of The Classic Period Maya From Chac Balam And San Juan, Ambergris Caye, Belize, Abigail L. Hornbeck

Honors Theses

Bioarchaeological research often uses skeletal remains to reconstruct patterns of activity and labor in past populations. This study examines potential sex-based differences in long bone morphology among individuals from the Classic Maya sites of Chac Balam and San Juan on Ambergris Caye, Belize. These coastal communities participated in maritime trade networks, and daily activities such as cargo transport, canoe travel, and fishing may have placed distinctive mechanical stresses on the skeleton. The goal of this study was to evaluate whether measurable differences in bone structure between males and females reflect differences in habitual activity patterns.

Two complementary methods were used …

Findings indicate that while both medical and dental education recognize rural background as a strong predictor of rural practice, medical education more …

The Ethical Imperative Of Public Health Institutions To Protect The Reproductive Autonomy Of Vulnerable Populations, Kennethea Wilson

Electronic Theses and Dissertations

This dissertation establishes the ethical responsibility of public health institutions to safeguard reproductive autonomy, especially among vulnerable populations. While reproductive decision-making is traditionally framed within individual clinical encounters, this work contends that reproductive autonomy is fundamentally a matter of public health ethics. Socioecological determinants, including social, legal, environmental, and structural factors, often constrain individuals’ ability to make meaningful reproductive choices, leading to preventable harm.

Reproductive autonomy is defined as the capacity to make informed decisions about whether and when to conceive, as well as how to parent. The dissertation critiques the sufficiency of clinical ethics frameworks, such as informed consent …
