Utilizing Machine Learning To Forecast Sector-Level Equity Returns From Sector-Level Financial Ratios, Greg Kuppenheimer Aug 2024

Utilizing Machine Learning To Forecast Sector-Level Equity Returns From Sector-Level Financial Ratios, Greg Kuppenheimer

Electronic Theses and Dissertations

Academics and equity analysts often utilize fundamental financial ratios to evaluate an industry's financial and operational performance. However, sophisticated econometric methods could be improved for estimating these ratios' importance in predicting sector-level stock return performance. To address this gap, gradient-boosted decision tree methods were applied to the WRDS sector-level financial ratio database to identify if financial ratios effectively forecast sector-level stock returns in future periods. The findings show that these ratios are predictive and economically material, both stand alone and in combination with other macroeconomic factors. Using these predictions, long and long-short sector-level portfolios were created, and most of these …

On Salvation And Genre: Fast Sermons In Seventeenth-Century New England, Daniel Patrick Mcgee Aug 2024

On Salvation And Genre: Fast Sermons In Seventeenth-Century New England, Daniel Patrick Mcgee

Electronic Theses and Dissertations

The fast sermon is an important and overlooked genre in the literary history of colonial New England, one which complicates theories about American puritanism underwritten by the imprecise narrative construct of the jeremiad. This thesis will argue that preachers used fast sermons to shape their communities, respond to major events, and provide competing interpretations of Congregationalist doctrine throughout the seventeenth century. Borrowing from the methodologies of new formalist criticism and Louis Althusser’s theory of material ideology, it will examine common themes, motifs, and rhetorical demands in John Wheelwright’s 1637 Fast Sermon, Thomas Shepard’s 1645 Wine for Gospel Wantons, …

Optimizing Remote Work Engagement And Performance, Jessica Chackoria Aug 2024

Optimizing Remote Work Engagement And Performance, Jessica Chackoria

College of Science and Health Theses and Dissertations

Remote work prevalence continues to remain higher than pre-pandemic levels and hybrid structures are increasingly becoming the norm. Therefore, it is important for researchers and organizations to understand how to optimize important employee outcomes, such as engagement and performance, in a remote work context. In this study, I addressed this need by investigating whether factors that have been found to enhance engagement and performance in traditional contexts—specifically, job design characteristics (task identity, task significance, autonomy, skill variety, and feedback) and microbreaks or small breaks during the workday—were positively linked with better remote work engagement and performance (task and contextual). The …

Patent Law And Access To Biotechnology, Enoch Otim Aug 2024

Patent Law And Access To Biotechnology, Enoch Otim

Technology and Economics Law Journal

The research analyzes the use of patents in a field other than industry and how they have a wider impact than the monetary gain of the patent holder. In recent years, patents have been taken out on organisms and gene sequences, which has a flow-on effect of jeopardizing any further research in that area and possible future developments. This is a serious issue in the fast-moving field of medical biotechnology. For example, researchers patented and developed a test that utilized and identified a gene sequence that was later patented by another party. The researchers may have to discontinue the test …

Oral Nutritional Supplement Prescription And Adherence Perspectives, Kristyn Bordelon Hood Aug 2024

Oral Nutritional Supplement Prescription And Adherence Perspectives, Kristyn Bordelon Hood

Master's Theses

Oral nutritional supplements (ONS) are nutrient-dense beverages that aid in meeting the nutrient needs of patients. Recent research has indicated that patient adherence to prescribed nutritional supplements may depend on palatability, tolerance, and taste fatigue. Registered Dietitian Nutritionists (RDNs) are healthcare professionals who may prescribe these supplements directly or make recommendations to the patient’s physician for a prescription, thereby influencing patient adherence. Little research has been documented regarding taste fatigue and the influences of the RDN’s decisions on patient adherence to nutritional supplement adherence. The purpose of this study was to gain an understanding of the perspectives of nutrition professionals …

A Longitudinal Study Assessing The Influence Of Salivary Cortisol, Alpha Amylase, And Interleukin-1Β Levels On Sleep And Physical Activity Among Emerging Adults, Bernardo Loiacono

College of Science and Health Theses and Dissertations

Emerging adulthood can be marked by psychological disorders and distress. Stress exposure activates several bodily responses involving the hypothalamic pituitary axis (HPA) and autonomic nervous system (ANS). Research into these systems involves the examination of several biomarkers including cortisol and alpha amylase. Basal values of these biomarkers have been linked to well-being and health outcomes. Also, stress biomarkers have been shown to influence physical activity (PA) which is salient because it is linked to chronic illness and disease (e.g., obesity, cancer, depression, diabetes). The present study aimed to explore the bidirectional relationships between basal stress biomarkers and daily PA in …

Finding The Silver Lining: The Role Of Supportive Social Environments, Keturah Platt

College of Science and Health Theses and Dissertations

Experiencing a significant loss can be one of the most challenging life experiences. The adverse effects of bereavement can disrupt a person’s overall health and well-being. While it is essential to fully acknowledge the negative outcomes of bereavement, it is equally important to recognize the potential for posttraumatic growth (PTG) following such experiences. PTG has been consistently observed in adults who have experienced various traumas, yet there is still much to learn about PTG among adolescents. Given that death is one of the most stressful life events for youth, bereaved adolescents are a crucial population for examining PTG. Those living …

Just Say Gay: An Exploration Of Authenticity And Connection; Queer Identified Therapists’ Lived Experiences Of Identity-Based Self-Disclosure, Courtney Dunne

Electronic Theses and Dissertations

The current sociopolitical climate in the United States continues to reinforce the complexities and nuances that mental health providers face when facilitating therapy. Over the past few years, anti-DEI legislation has aimed to control the narrative in educational and therapeutic settings regarding what therapists and educators are permitted to teach and share about themselves (Flannery, 2024). At the same time, anti-LGBTQ+ rhetoric continues to dominate the media and further marginalizes individuals whom are in the queer community. In turn, LGBTQ+ individuals continue to face an increased risk for homelessness, substance use disorders, and suicide, which particularly has impacted LGBTQ+ youth …

When Social Media Recruiting Goes Wrong: A Cautionary Tale Of Sample Engagement, Ezra N. S. Lockhart, Joel B. Goodin

The Qualitative Report

Doctoral candidates’ experiences with recruiting participants vary in many ways. While some execute plans with ease, others implement their strategic plan for recruitment only to find that it does not work well or does not work at all. While successful recruitment is rarely reflected upon, the candidate who experiences unexpected difficulty with recruitment has several potential negative effects including increased time to degree completion, increased program and recruitment costs, and increased potential for dropout. In this case study, we present a cautionary tale of sample engagement from the gaming community where a doctoral candidate experienced doxxing, social media banning, and …

Slow Ramping Emerges From Spontaneous Fluctuations In Spiking Neural Networks, Jake Gavenas, Ueli Rutishauer, Aaron Schurger, Uri Maoz Aug 2024

Slow Ramping Emerges From Spontaneous Fluctuations In Spiking Neural Networks, Jake Gavenas, Ueli Rutishauer, Aaron Schurger, Uri Maoz

Psychology Faculty Articles and Research

The capacity to initiate actions endogenously is critical for goal-directed behavior. Spontaneous voluntary actions are typically preceded by slow-ramping activity in medial frontal cortex that begins around two seconds before movement, which may reflect spontaneous fluctuations that influence action timing. However, the mechanisms by which these slow ramping signals emerge from single-neuron and network dynamics remain poorly understood. Here, we developed a spiking neural-network model that produces spontaneous slow ramping activity in single neurons and population activity with onsets ~2 s before threshold crossings. A key prediction of our model is that neurons that ramp together have correlated firing patterns …
