A Multilevel Analysis Of Arrest For Sexual Assault In The United States: The Effect Of Incident, Police Department, And Community Factors, Erin Elizabeth Hoffman

College of Science and Health Theses and Dissertations

Police officers play an important role for sexual assault survivors seeking help from the criminal legal system in the United States. One of their main responsibilities is to investigate the crime to determine if there is enough evidence to arrest a suspect. Previous literature has documented police arrest decisions in sexual assault cases are influenced by legal and extralegal factors—factors that are legally relevant (e.g., presence of DNA evidence) and irrelevant (e.g., victim race) in a case. These factors span multiple levels of analysis, namely the incident (e.g., whether a weapon was used) and police department (e.g., % of woman …

Gi, Pain, Anxiety, And Mood Symptoms Among Youth With Fapds, Helen Bedree

College of Science and Health Theses and Dissertations

Pediatric functional abdominal pain disorders (FAPDs) frequently persist into adulthood, thus developmental considerations are critical for monitoring symptom presentation and tailoring treatments. In addition to core symptoms, such as pain and gastrointestinal symptoms, mood and anxiety symptoms often co-occur as well as negative impacts on functioning and quality of life. The current study took a developmental approach to assess core pain, gastrointestinal, anxiety, and mood symptoms among youth with FAPDs (N = 105), as well as agreement across youth and their caregivers on these key symptoms. Developmental stages included early childhood, middle childhood, adolescence, and emerging adulthood. A cluster …

The Impact And Perceptions Of Return-To-Office Mandates, Brooke E. Nyberg

College of Science and Health Theses and Dissertations

In the aftermath of stay-at-home mandates that resulted from the COVID-19 pandemic, many organizations have reinstated mandates requiring that employees return to the office either full-time or a few days per week. Although research has been conducted on the benefits and consequences of remote work throughout the pandemic, research is lacking on the perceptions of the return-to-office mandates and how these mandates impact employees. This study aimed to comprehensively understand what employees think and feel about a return-to-office mandate as well as identify group differences and impacts of the method in which the RTO mandate was communicated. To do so, …

Examining Changes In Control Beliefs And The Role Of Self-Determination In A Cognitive-Behavioral Intervention For Elementary-Aged Students, Laura Saldana

College of Science and Health Theses and Dissertations

To date, cognitive behavioral intervention studies for youth focus on symptom reduction to evaluate treatment efficacy without studying changes in youth coping. The present study, backed by Motivational Theory of Coping and Self-Determination Theory, used a randomized control trial design to examine the effects of a brief (5-session), group-based, cognitive-behavioral intervention called Act and Adapt – SP on adaptive coping, maladaptive coping, competence, and relatedness in a sample of academically underperforming 3^rd and 4^th graders (N = 56; M_age = 8.8 years; 62.5% female; 78.6% Latinx). Act and Adapt – SP was designed for Saturday …

A Mixed Methods Survey To Highlight Retrospective Drug Spending, Dillon Peter Thorpe

College of Science and Health Theses and Dissertations

The financial impact of substance use is poorly understood. What research has been conducted has focused on societal and medical costs, rarely on the personal finances of substance users. Less research has been conducted on the finances of people currently in recovery and abstinence. To fill in this gap, 284 current Oxford House residents completed a survey that inquired about demographics, spending habits, and reasons for staying in Oxford House. Following analysis, it was found that previous drug/alcohol spending is a highly variable metric, with a range of $0-$30,000 per month. In addition, the sample was homogenous in terms of …

The Effect Of Reading Goals On Conspiracy Believability And Memorability, Leah Patricia O'Neill

College of Science and Health Theses and Dissertations

Previous research shows that individuals who are assigned different goals for reading remember and comprehend text differently, which might also influence how individuals read texts that contain conspiracy theories. This research has revealed a connection between scores on the Schizotypal Personality Questionnaire-Brief (SPQ-B) and conspiracy theory belief, such that those who score higher are more likely to believe in conspiracy theories. Therefore, this study investigated the influence of reading goals (i.e., study vs entertainment) and different types of conspiracy theories (i.e., familiar and less familiar) on participant’s believability ratings for conspiracy texts. Participants were assigned a reading goal prior to …

The Impact Of Popularity Pressure: A Moderated Mediation Model, Molly Clare Walker

College of Science and Health Theses and Dissertations

Adolescence is a critical development stage where social pressures can significantly impact interactions and behavior. One such pressure, popularity pressure, refers to adolescents’ perceived obligation to meet social expectations related to having a popular status. Prior research by Wright (2020) highlights that perceived popularity pressure, often driven by parental and peer influence, is linked to maladaptive behaviors such as relational aggression. Despite these findings, limited research has yet to explore the effect of popularity pressure on adolescents’ internalizing symptoms such as anxiety and depression, in addition to the underlying mechanisms through which popularity pressure impacts adolescents’ mental health and behavior. …

Early Diagnosis And Detection Of Skin Cancer Using Deep Neural Network Models And Feature Extraction From Pre-Trained Cnns, Sahil Khanna

Harrisburg University Dissertations and Theses

Skin cancer is one of the most common and lethal cancer types. While accurate diagnosis at an early stage is essential for skin cancer treatment it remains difficult to achieve in many regions due to lack of sufficient dermatologists and proper diagnostic equipment. Prior studies show Convolutional Neural Network (CNN) models excel at skin lesion classification and consistently achieve better results than standard diagnostic practices. However, the focus of many studies remains confined to image-based learning while neglecting useful patient metadata that could improve prediction accuracy. This research project created a specialized CNN model to classify skin lesions and evaluated …

Investigating Momentary Body Image Disturbance, Affect, And Disordered Eating Among College Students, Allison T. Cunning

USF Tampa Graduate Theses and Dissertations

Despite evidence that eating disorders are associated with elevated mortality rates, increased risk of suicide, and societal and financial burden, treatment outcomes for individuals with eating disorders remain poor. Body image disturbance has emerged as a robust risk factor for the development and maintenance of disordered eating (e.g., overeating, binge eating, purging, restriction) and theoretical and clinical perspectives most commonly operationalize body image disturbance as a trait construct. However, empirical evidence suggests body dissatisfaction may fluctuate, and these fluctuations may play an important role in the relationship between risk factors and disordered eating. The current study employed ecological momentary assessment …

Roles Of Organic Agriculture For Water Optimization In Arid And Semi-Arid Regions, Shikha Sharma, Matt A. Yost, Jennifer R. Reeve

Plants, Soils and Climate Student Research

Water scarcity is a critical challenge in arid and semi-arid regions, where agricultural water consumption accounts for a significant portion of freshwater use. Conventional agriculture (CA) methods with high reliance on chemical and mechanical inputs often exacerbate this issue through soil degradation and water loss. This review aims to examine how different organic practices, such as mulching, cover cropping, composting, crop rotation, and no-till (NT) in combination with precision technologies, can contribute to water optimization, and it discusses the opportunities and challenges for the adoption and implementation of those practices. Previous findings show that organic agriculture (OA) may outperform CA …

Cervical Deciduosis In Early Pregnancy Mimicking Malignancy: A Report Of Two Cases, Ajit Sebastian, Nada Salih, Shiby Jose, Tamima Al Dughaishi, Vaidyanathan Gowri

Sultan Qaboos University Medical Journal

Deciduosis is a benign condition characterised by the transformation of subepithelial connective tissue into decidual-like cells, typically occurring in response to hormonal changes during pregnancy. Although benign, cervical deciduosis may macroscopically resemble malignant lesions, leading to diagnostic uncertainty. This report presents two cases of cervical deciduosis diagnosed in early pregnancy. Both patients presented with first-trimester vaginal bleeding, and speculum examination revealed extensive wart-like lesions covering the cervix. Histopathological examination of cervical biopsies confirmed decidual changes. In pregnant women presenting with threatened miscarriage, a thorough local examination and biopsy of atypical cervical lesions are essential to exclude malignancy. As cervical deciduosis …

Intimate partner violence (IPV) can be found in many cultures throughout the world, with varying levels of acceptability, victimization, and perpetration. Approximately one in five couples report experiencing at least one instance of IPV in a given year. Women are victims of IPV more frequently than men, and experience more severe injuries. 20% of women report a lifetime history of physical IPV victimization by their current or past partners. Further, women are also ten times more likely to be killed due to IPV than men are. Presently, empirical research literature surrounding the dynamics and impacts of IPV is heavily focused …

Freeing The Fremont: Visions Of A Post-Automobile Portland Highway Bridge, Henry Senters

University Honors Theses

The Fremont Bridge is an iconic piece of highway transportation infrastructure in the city of Portland, Oregon. Unfortunately, it is one of only three Willamette bridges in the city that does not allow any pedestrian access, except for a single day every year during an annual bicycling event. Consider, however: what if that were to change, in a future less dependent on private automobile usage? Drawing on historical precedents of pedestrian and car-free bridges, this thesis proposes three types of pedestrian-focused programs which a car-free Fremont Bridge could host, each of which speaks to a current aspect of civic life …

Changing Minds, Changing Modes: Optimizing Public Perception Strategies For Urban Cycling Through Behavior Change Theory, Brandon Barnhart

University Honors Theses

This thesis addresses the recent decline in bicycle mode share in cities like Portland, Oregon, despite decades of investment in cycling infrastructure. While the "build it, and they will come" approach succeeded through the early 2000s, it no longer meets targets for bicycle use or broader goals related to sustainability, congestion, health, and safety. A new approach is needed that effectively rebuilds the cultural and behavioral components of cycling. This research asks: What role can behavior change theory play in increasing the effectiveness of public perception campaigns to promote urban cycling? Using a qualitative methodology, this study draws on behavior …

How Mindfulness-Based Stress Reduction (Mbsr) Techniques Affect Obsessive-Compulsive Disorder: A Literature Review, Piper Ritke

Honors Theses

This literature review examines the potential effectiveness of mindfulness-based stress reduction (MBSR) as a non-invasive therapeutic intervention for individuals with obsessive-compulsive disorder (OCD). Traditional treatments for OCD, such as cognitive behavioral therapy (CBT) and exposure and response prevention (ERP), are evidence-based but can be distressing for some patients. MBSR, originally developed by Jon Kabat-Zinn, emphasizes nonjudgmental awareness of thoughts and may offer a less intrusive alternative. Three peer-reviewed studies were analyzed: a randomized controlled trial comparing MBSR with cognitive therapies, a technology-supported mindfulness intervention utilizing EEG feedback, and a case study documenting individualized MBSR treatment. All studies demonstrated reductions in …
