Role Of Gut-Liver-Brain Axis In Neuropsychiatric Symptoms Of Parkinson’S Disease, Raveena Dhanani Ratnayake

Student Theses and Dissertations

Neuropsychiatric symptoms (NPS), such as depression, and anxiety, and mild cognitive impairment (MCI), often precede motor symptoms in Parkinson’s disease (PD), highlighting the need for early biomarkers and mechanistic insights. Gut-microbiome-related metabolites, including secondary bile acids, influence lipid homeostasis and mitochondrial function, impacting neuropsychiatric and neurodegenerative disorders. This study examines metabolic alterations in PD, focusing on lipid metabolism, bile acids, acylcarnitine, and amino acids. Our findings showed significant changes in lipid metabolism, transsulfuration pathway, bile acids, acylcarnitine, and amino acids in PD severity and NPS. Specific lipid subclasses were linked to NPS, cognitive impairment, and motor impairment. Given the limited …

Perceptions Of Teacher Recruitment And Retention Programs That Focus On Financial Incentives In Rural Georgia School Systems, Ronald Hill

Student Theses and Dissertations

This study explores the perceptions of teacher recruitment and retention programs in rural Georgia, emphasizing the role of financial incentives. Rural school districts face persistent challenges in maintaining a stable educator workforce, largely due to low retention rates. Using Herzberg’s Two-Factor Theory, this study examines how salary as a function of job satisfaction influences teachers' decisions to enter and remain in the profession. Through a qualitative case study, interviews with 24 rural Georgia educators, document analysis, and member checking were conducted to assess perceptions of recruitment and retention. The findings highlight the critical impact of salary, with competitive pay being …

College And Career Readiness Of Students With Autism In The Dallas/Fort Worth Metropolitan Area, James Daniel Hobbs

Student Theses and Dissertations

Autism is a spectrum disorder involving individualized disabilities in social interactions, self-expression, and behavior control. Those diagnosed typically exhibit challenges in at least two of these areas. Many individuals with autism are identified through evaluations in public schools. Under the Individuals with Disabilities Education Act, public schools must provide disabled students with a free and appropriate public education through special education. In Texas, autism is one of 13 disabilities that qualify a student for special education services. Once in special education, students receive an individualized education plan, which includes goals for life after high school. The Texas Education Agency tracks …

Social Perception Of Bipolar Disorders On Employment Outcomes, Mary E. Henson

Student Theses and Dissertations

An important component to quality of life in those living with bipolar disorders is employment. Employment gives people an opportunity to provide for themselves and others, granting them the ability to live bountiful lives. For those with mental health diagnoses, it also provides them with economic access to affordable treatment. Literature agrees that many people with these diagnoses, specifically people with bipolar disorders, are less likely to be employed and maintain employment. It is likely that a lack of employment is due to stigma faced from employers and colleagues. Many studies have investigated internal stigma of bipolar disorders, but there …

Effects Of Intensity During Wingate Anaerobic Testing On Pedal Power Asymmetry In Recreationally Active Individuals, Balqees Mraiyan

Student Theses and Dissertations

This study examined the differences between three different intensity levels during a Wingate Anaerobic test (WAT) on the pedal power asymmetry and descriptive variables in recreationally active individuals. Six recreationally active volunteers completed a counterbalanced design of three separate WAT at different intensities. Test intensities consisted of a low resistance (5%), traditional resistance (7.5%), and a high resistance (8.7%) of each individual’s body mass in kilograms (kg). Descriptive data (age, weight, height, blood pressure, and heart rate) were also collected. A two-way repeated measures analysis of variance (ANOVA) examined the differences between each intensity level across all four sprints with …

Nurses’ Role In Reducing Mental Health Stigma In Healthcare, Olufunmilayo Elizabeth Adeloye

Walden Dissertations and Doctoral Studies

This Doctor of Nursing Practice (DNP) project implemented a targeted educational intervention to reduce mental health stigma among healthcare providers. Mental health stigma, often resulting in misdiagnosis, delayed treatment, and decreased patient engagement, represents a significant barrier to effective nursing practice. The project’s practice-focused question examined whether an educational program could improve provider knowledge and attitudes toward mental illness. Using the ADDIE model (analysis, design, development, implementation, and evaluation), a needs assessment at a family practice and behavioral healthcare clinic identified gaps such as judgmental perceptions, avoidance behaviors, and lack of empathy among providers. An extensive literature review supported the …

The Promotion Of Physical Activity For Use In Alzheimer's Disease Prevention Trials In Adults With Down Syndrome: Results From A 12-Month Randomized Trial., Lauren T. Ptomey, Brian C. Helsel, Richard A. Washburn, Robert N. Montgomery, Ron Krebill, Jessica C. Danon, Joseph R. Sherman, Daniel Forsha, Amy Bodde, Amanda N. Szabo-Reed, Anna M. Gorczyca, Joseph E. Donnelly

Manuscripts, Articles, Book Chapters and Other Papers

INTRODUCTION: Alzheimer's disease (AD) is the leading cause of death in individuals with Down syndrome (DS). Participation in moderate-to-vigorous physical activity (MVPA) may prevent or delay the onset of AD. Therefore, we evaluated the potential effectiveness of a remotely delivered home-based group exercise (≈8/group) to increase daily MVPA and cardiorespiratory fitness in adults with DS to a level that may be associated with delaying AD in adults with DS.

METHODS: Adults with DS ((n = 81, age ≈27 years 55% female) without dementia were randomized (2:2:1) to a 12-month intervention, which included 40-min exercise sessions scheduled once (remote low …

The Rogue Private Company And National Defense Emergencies, Gavin Small

Duke Journal of Constitutional Law & Public Policy Sidebar

This Note explores two overlapping challenges in the United States constitutional and political system. First, the United States increasingly relies on private companies for technologies necessary for national defense. This has given outsized power to a few unelected corporations and people who might have their own incentives that misalign with those of the United States. This is particularly dangerous in an emergency situation where the United States government, not a private company with its own interests, should be making decisions regarding national security. As an example, this Note focuses on the massive role that the company SpaceX plays in the …

Forcing Our Hand: Evaluating The Use Of Force In Responses To Wrongful Detentions Abroad, Tyler J. Marovitz

Duke Journal of Constitutional Law & Public Policy Sidebar

Wrongful detentions are on the rise. Over the past ten years, U.S. nationals have increasingly found themselves detained abroad upon spurious allegations, facing trumped-up charges, and deprived of basic due process protections. Most of these detentions occur in countries hostile to the United States: Russia, Iran, North Korea, China, and Venezuela. The U.S. has opted to release rightfully detained foreigners to those nations in exchange for its wrongfully detained nationals. All of this perpetuates a “prisoner bazaar” that encourages unscrupulous nations to continue their bad-faith detentions of U.S. nationals. This Note investigates this emerging issue through a use of military …

Multimodal Person Evaluation: First Impressions From Faces, Voices, And Names, Mila Mileva

School of Psychology

We form a first impression every time we meet someone unfamiliar to us. When this happens, we often have access to information about this person’s appearance, voice and the first thing we learn about them is usually their name. Despite this, much of what we know about social evaluation processes has been almost exclusively based on facial information. Here, approximately 45,000 spontaneous first impression descriptors were sampled to identify the most common judgements we make when presented with information about someone’s face, voice, and name at the same time as well as when presented with information about their voice or …

Self-Efficacy Of Kindergarten, First, And Second Grade Educators Teaching Students With Behavioral Issues In South Carolina Public Schools, Kathryn Sommer-Gough

Student Theses and Dissertations

Teaching students with behavioral challenges can impact elementary school teachers’ self-efficacy. This study examined the perceived lack of preparation among educators in managing such students. Guided by Bandura’s self-efficacy theory, this qualitative phenomenological study explored the experiences of kindergarten through second-grade general education teachers. Ten South Carolina teachers participated in three Zoom interviews each, discussing their self-efficacy and administrative support. Analysis revealed five key themes: self-efficacy, training, effects of students with behavioral issues, support, and frustrations. Teachers reported increased confidence after developing classroom management strategies, though these techniques were largely self-taught rather than formally provided. Future research should examine the …

The War On Tourer: An Analysis In Terrorism’S Effect On Tourism, Jacob M. Strawn

Student Theses and Dissertations

Tourism is the third largest global export, representing seven percent of all global trade(UNWTO 2021). Many developing countries now depend on tourism to achieve sustainableeconomic growth, a core component of the UN’s 2030 Sustainable Development Goals. Priorstudies of this phenomenon focus on isolated case-studies, mostly based on limited data. Inthis thesis I examine how terrorist incidents and fatalities affect international tourist arrivalsin 93 developing countries from 1995 to 2020. Special focus is placed on potential variablesthat may effect some countries more than others like Post-9/11 Anxiety. An increase in terrorattacks is associated with a decrease in tourism.

Stepping Into Motherhood: Pregnancy-Induced Changes To Foot Structure And Biomechanics, Lauren R. Williams

Theses and Dissertations

INTRODUCTION: Pregnant women have an elevated risk of developing lower limb musculoskeletal disorders, likely due to the rapid increase in body mass and joint laxity. While a few studies have evaluated changes in static foot posture due to pregnancy, it is unclear if body mass or joint laxity is the primary driver. Additionally, how pregnancy affects the mechanics of the foot during dynamic movements is still not understood. PURPOSE: The purpose of this study is to investigate the foot's response to pregnancy. First, we examined foot tissue characteristics across pregnancy, specifically plantar fascia (PF) stiffness, length, and thickness. Additionally, we …

Yield And Pungency Of Eight Onion Varieties And Their Response To Sulfur Fertilizer On Fine-Textured Soil, Charlie Rohwer, Jesen Hosch, Brianna Hayward, Cindy Tong

Midwest Vegetable Trial Reports

Onions are notable for their pungency, caused by sulfur-containing compounds. Fine-textured soils high in organic matter, or soils fertilized with organic amendments, are unlikely to require additional sulfur for maximum onion yield. We were interested in the impacts of additional sulfur (in such a situation, unlikely to be sulfur-limited) on pungency, soluble solids, and yield in eight onion varieties. We carried out a study in 2024 in southern Minnesota, designed as a split-plot (onion variety as the whole-plot) with four replicates. Heavy rainfall caused substantial unmarketability in our trial, with ‘Ringmaster’ suffering the most loss (11% of planted ‘Ringmaster’ were …

Online Hyperparameter Tuning For Llm Optimization, Ethan Lin, Nathan Yu, Jeromy Chang

Computer Science and Engineering Senior Theses

Large Language Models (LLMs) are becoming increasingly popular in modern society. However, despite their popularity, the deployment of LLMs in real-world scenarios is extremely challenging due to substantial computational costs and memory constraints. Edge devices, like smartphones and IoT devices, lack resources needed to run these models locally, instead offloading computations for cloud computing. Cloud computing requires users to send their data over the internet leading to numerous privacy and security concerns. In some domains, such as health and finances, sending such sensitive information is not an option. Existing solutions to compress or increase inference speed include Small Language Models …

Introduction: Teenage pregnancy remains a critical global health issue, particularly in low- and middle-income countries. The intergenerational transmission of teenage pregnancy underscores the need for targeted interventions. Existing research on intergenerational approaches is fragmented, with varying methodologies and outcomes. This scoping review seeks to address this gap by answering the following research questions: What are the available intergenerational interventions for teenage pregnancy, and what are the associated risks and protective factors for early and late teenage pregnancy?

Methods and analysis: This study does not involve primary data collection and therefore does not require ethical approval. The review will be conducted …

As Good As It Gets? Comparing Clients’ And Treatment Providers’ Perceptions Of Engagement Barriers And Facilitators For Exposure And Response Prevention Ocd Treatment, Samuel Mutschler-Aldine

University Honors Theses

This mixed-methods study compared clients' and providers' sentiments toward research-based themes on barriers and facilitators of client engagement in treatment. For individuals with Obsessive-Compulsive Disorder (OCD), engagement in Exposure and Response Prevention (ERP) therapy is a crucial ingredient of successful treatment and symptom remission. Therefore, it is imperative to thoroughly understand the perspectives on engagement barriers and facilitators of people with field experience: ERP patients and therapists.

The researcher administered two Qualtrics surveys to thirty current providers and six current or former clients of ERP for OCD. Each survey contained five-point, Likert-style scales to measure the level each participant agreed …

Efficacy Of New Jersey's Child Protection Policy Among Local Superior Courts, Nerissa G. Collins

Walden Dissertations and Doctoral Studies

Despite the existence of New Jersey Department of Children and Family (NJDCF) policy guidelines, it remained unclear whether New Jersey superior courts consistently applied these principles and guidelines in Department of Child Protection and Permanency (CP&P) child abuse cases. Limited research had been conducted to examine how courts interpreted and adhered to these policies in legal rulings, leaving a gap in understanding how NJDCF principles influenced judicial decision-making. This gap in the literature made it difficult to assess whether policy guidelines effectively shaped court outcomes in ways that supported child protection and welfare. Child protective advocate attitudes and opinions concerning …
