Three Essays In International Trade And Macroeconomics, Jun Nie

Economics Theses and Dissertations

This dissertation examines the impact of international trade and trade policy on key economic outcomes, including income and productivity. The first chapter investigates the role of trade-induced technology diffusion in shaping global income inequality. When bilateral trade facilitates technology transfer, such diffusion can account for up to 85% of the income gap across countries. The second chapter focuses on the determinants of international trade in services. It highlights a significant link between service and manufacturing trade, conditional on the presence of foreign direct investment (FDI) relationships between trading partners. The third chapter evaluates the 2020 U.S. presidential election, aiming to …

Leadership Self-Efficacy: Exploring Social Workers’ Perceived Ability To Serve On School Boards, Jessica Zavalza

Walden Dissertations and Doctoral Studies

The low representation of social workers serving on school boards is a social work practice problem because it limits their leadership ability to advocate for student mental health and influence policy change at the local and state levels of education. Therefore, addressing this practice problem within the context of clinical social work is crucial for improving student mental health outcomes and overall student well-being. Guided by Bandura’s self-efficacy theory, this qualitative study was conducted to explore the connection between social workers’ leadership self-efficacy and their willingness to pursue policymaking roles at the local and state school board levels. With the …

Statistical Methods For Joint Outcome Modeling And Dynamic Assessment Of Recurrent Events, Zifang Kong

Statistical Science Theses and Dissertations

Recurrent event data frequently arise in clinical studies where individuals experience repeated, possibly related, events over time. These data are often accompanied by sparse and irregular longitudinal measurements, creating challenges for traditional joint modeling approaches that struggle to account for time-dependent associations and within-subject correlations. We propose FRAILTY (Functional Regression with AutoRegressIve fraiLTY), a novel two-step framework that integrates functional principal component analysis (PACE) with a dynamic frailty model featuring autoregressive structure. FRAILTY accommodates both scalar and functional predictors and captures within-subject dependence across recurrent events. To further extend its utility, we develop a multivariate joint modeling framework that simultaneously …

Towards Reliable Clinical Applications Of Ai Models In Radiotherapy, Biling Wang

Statistical Science Theses and Dissertations

Over the past decade, artificial intelligence (AI), particularly through deep learning (DL) techniques, has made significant strides in fields like computer vision (CV) and natural language processing (NLP), leading to transformative advancements across numerous applications. This progress has sparked considerable enthusiasm within the medical field, where DL-related research has grown exponentially since 2015. However, despite these promising developments, the real-world deployment of DL models in healthcare remains limited, especially in safety-critical domains such as radiotherapy (RT), where reliability, safety, and sustained performance are critical. This thesis addresses three core challenges associated with the clinical application of DL models: (1) post-deployment …

Establishing Operational Foundations In A Faculty-Led Clinic: Workflow Design, Role Development, And Service Planning, Rebecca Wensmann

Faculty And Administrators' Perspectives Of Generative Artificial Intelligence At An Online Higher Education Institution, Devon Edmund

Walden Dissertations and Doctoral Studies

The problem addressed in this study was that faculty and administrators in higher education are not prepared to address the use of generative artificial intelligence (GAI) innovations in institutional policies and practices. The pace of advancement of GAI in higher education (HE) left institutions to determine policies and practices without industry best practices or guidelines established by accreditors or regulatory bodies. The purpose of this qualitative study was to explore the perspectives of faculty and administrators at an online HE institution on how to respond to the emergence of GAI through institutional policies and practices. The theory supporting the study …

The Benefits Of High Phosphate Concentration (10n : 1p) And Diagonal Orientation On The Ex Situ Grow-Out Of Caribbean Coral Juveniles, Ashley Shen

All HCAS Student Capstones, Theses, and Dissertations

As coral reefs keep declining, it is imperative to increase coral production ex situ for restoration, but this requires culture protocols to be optimized. This study examined the impacts of grow-out orientation and phosphate concentration (and nitrate (N): phosphate (P) ratio) on the survival and growth of Montastraea cavernosa and Pseudodiploria clivosa juveniles from 3 to 9 months old. Pristine reefs typically have low nitrate (0.12μmol/L) and low phosphate (0.03μmol/L) concentrations, leading to N:P ratios of 4-16 N: 1P. In recirculating tanks, it is difficult to lower nitrate concentrations below 25μmol/L. Here we hypothesized that increasing the phosphate concentration in …

Rehman, Carol J. Saunders, Shiva Ganesan, Vaidehi Jobanputra, Stephen W. Scherer, Ingo Helbig, Amita Sehgal

Manuscripts, Articles, Book Chapters and Other Papers

Through international gene-matching efforts, we identified 10 individuals with ultrarare heterozygous variants, including 5 de novo variants, in BMAL1, a core component of the molecular clock. Instead of an isolated circadian phenotype seen with disease-causing variants in other molecular clock genes, all individuals carrying BMAL1 variants surprisingly share a clinical syndrome manifest as developmental delay and autism spectrum disorder, with variably penetrant sleep disturbances, seizures, and marfanoid habitus. Variants were functionally tested in cultured cells using a Per2-promoter driven luciferase reporter and revealed both loss-of-function and gain-of-function changes in circadian rhythms. The tested BMAL1 variants disrupted PER2 mRNA …

Summary:

Disability status is rarely included in health research and policy, including intersectional research, perpetuating health inequities for this population. This paper calls on researchers and policymakers to take concrete steps to advance health equity for disabled people, including those at the intersections of disability, race, ethnicity, poverty, and other marginalized identities. We propose four strategies with recommendations to promote: a) meaningful engagement of disabled and multiply marginalized people in research and policy planning; b) cohesive, systemic disability data collection and analyses; c) use of intersectional approaches to examine structural drivers of health inequities; and d) leveraging of administrative data …

Method For Target Detection In A High Noise Environment Through Frequency Analysis Using An Event-Based Vision Sensor, Will Johnston, Shannon Young, David Howe, Rachel Oliver, Zachary Theis, Brian Mcreynolds, Michael L. Dexter

Faculty Publications

Event-based vision sensors (EVSs), often referred to as neuromorphic cameras, operate by responding to changes in brightness on a pixel-by-pixel basis. In contrast, traditional framing cameras employ some fixed sampling interval where integrated intensity is read off the entire focal plane at once. Similar to traditional cameras, EVSs can suffer loss of sensitivity through scenes with high intensity and dynamic clutter, reducing the ability to see points of interest through traditional event processing means. This paper describes a method to reduce the negative impacts of these types of EVS clutter and enable more robust target detection through the use of …

Opening The Black-Box Of Mental Disorders: An Actor-Network Theory Analysis Of Schizophrenia, Brandalyn Morris

McNair Scholars Manuscripts

Schizophrenia is a poorly understood mental dysfunction. It is culturally specific and encompasses several disease entities that defy robust classification. Using a few of the methodological notions from Bruno Latour’s Actor-Network Theory (ANT), this research seeks to disambiguate schizophrenia. The scope and focus of this examination will be restricted to three actors/actants within the assemblage of this mental disorder. By appropriating tools and terminology from ANT to reveal human and non-human actors and actants within the DSM classification system, the medical model of mental illness, and psychopharmacology, the objective of this research is to describe how the current concept of …

Because of this, it is important to understand how recreational activities, common in desert environments, impacts dryland ecosystems' ability to perform ecosystem services. The growing popularity of outdoor recreation in Western US poses a threat to desert ecosystems, and unregulated activities can harm soil health, particularly the presence and functioning of biological soil crusts (biocrusts). This study uses the Indian Creek Special Recreation Management area in Bears Ears National Monument, Utah, USA, as a case study for recreation impacted desert ecosystems. It examines the …

Consequences Of The Double Empathy Problem Within The Clinical Environment: A New Model For Neuroinclusive Care, Sofia Jimenez

Theses and Dissertations

As diagnoses of autism spectrum disorder (ASD) rise, the neurodiversity and autistic self-advocacy movements have challenged traditional deficit-based clinical models and called for more inclusive, affirming approaches to care. Recent research disputes the long-held belief that autistic individuals have deficits in perspective-taking, revealing that miscommunication between autistic and neurotypical individuals results from mutual misunderstanding, a concept known as the double empathy problem (DEP; Milton, 2012), with the triple empathy problem (TEP) extending this framework to healthcare settings. Our study investigates the consequences of the DEP and TEP within clinical environments, focusing on interactions between neurotypical speech-language pathologists (SLPs) and adult …

Exploring Soil-Derived Antimicrobials For Inhibiting Dairy-Associated Pathogens And Spoilage Bacteria, Michael Joseph Moran

Theses and Dissertations

Spore-forming bacteria are among the most problematic contaminants in fluid milk. They can survive pasteurization, grow at refrigeration temperatures, and secrete heat-stable enzymes, making them a major cause of spoilage in both pasteurized and reconstituted milk products. Current nonthermal strategies for reducing spore counts, including microfiltration and bactofugation, are often costly and inconsistent. The increasing consumer demand for natural additives in food products has sparked interest in the use of bacterially-derived antimicrobial compounds, particularly those from generally recognized as safe (GRAS) organisms, as an alternative method of dairy preservation. This study explores the antimicrobial potential of ten soil-derived Bacillus and …

Thompson, David Veale, James T.R. Walters, Christopher Hübel, Gerome Breen, Thalia C. Eley

School of Psychology

BACKGROUND: Functional impairment in daily activities, such as work and socializing, is part of the diagnostic criteria for major depressive disorder and most anxiety disorders. Despite evidence that symptom severity and functional impairment are partially distinct, functional impairment is often overlooked. To assess whether functional impairment captures diagnostically relevant genetic liability beyond that of symptoms, we aimed to estimate the heritability of, and genetic correlations between, key measures of current depression symptoms, anxiety symptoms, and functional impairment.

METHODS: In 17,130 individuals with lifetime depression or anxiety from the Genetic Links to Anxiety and Depression (GLAD) Study, we analyzed total scores …

The novel (nua) kinases 1 and 2 are two of 12 AMP-activated protein–related kinases whose signaling pathways are involved in cancer progression, as well as neurologic, fibrotic, and inflammatory diseases. Currently, there are 80 Food and Drug Administration-approved kinase inhibitors which target roughly 24 of the 500+ known human kinases, leaving most kinases underexplored, including NUAK1 and NUAK2. Thus, there is a critical need for selective inhibition of NUAK1 and NUAK2 signaling. Here, we review the protein structure, known upstream regulators and downstream targets, and expression profiles of NUAK1 and NUAK2 in cancerous compared to noncancerous tissue. We also delineate …

“I Laughed Along For Years But Hated It Inside:” Understanding Nuance In Peer Teasing Experiences Using A Thematic Analysis, Naomi C.Z. Andrews, Molly Dawes Ph.D.

Faculty Publications

Introduction

Peer teasing is ubiquitous, yet ambiguous in nature. Despite recent attempts to delineate and clarify differences in teasing experienced as playful versus harmful, there remains overlap and complexity in these interactions. In the current study, we present a conceptual model of teasing, which includes many nested features that dynamically interact within a teasing episode. Using this conceptual model to guide our work, the goal of the current study was to use qualitative inquiry to bring further conceptual clarity to the overlap between teasing that is experienced as playful versus harmful.

Method

Using semi-structured interviews, we asked university students ( …

Approximately 3% of organ transplant recipients will be diagnosed with an invasive fungal infection (IFI), with 10%-47% being fatal. The source of IFI is typically not known, but Candida spp. cause the majority of IFI cases. We obtained intestines from two types of organ donors, brain-dead (BD) (n = 7) and donation after circulatory death (DCD) (n = 5), to sample microbes from the mucosal surface and the lumen. BD donors were parenterally fed and treated with corticosteroids in the days before procurement, whereas DCD donors were enterally fed and not given corticosteroids. We found fungi present in …
