A Meta-Analysis Of Cannabis Research: Is There Evidence Of Lasting Neurocognitive Effects?, Mark J. Crisafulli

Graduate Thesis and Dissertation 2023-2024

Cannabis use in the United States has generally increased over the past decade as more States have legalized recreational use. In conjunction with changes to the chemical makeup, which has made available cannabis more potent, the long-term effects experienced by cannabis users may have changed, and more individuals may be effected. The current study replicated the methods used in Schreiner & Dunn (2012) and Grant et al. (2003) to conduct a meta-analysis examining the neurocognitive effects of cannabis after abstinence lasting a period of at least 25 days. Previous research has found mixed results, with some studies finding significant differences …

Examining Changes In Pain Sensitivity Following 8 Minutes Of Cycling At Varying Exercise Intensities, Brandi B. Antonio

Graduate Thesis and Dissertation 2023-2024

This study assessed the effect of an eight-minute cycling intervention using varying intensities on exercise-induced hypoalgesia (EIH). Generally, current research examines EIH using protocols that last for more than 10 minutes and reach 75% of an individual's VO2 peak. The main objective of this study was to examine the effect of varying intensities on pressure pain threshold (PPT) and heat pain threshold (HPT) at the thigh and forearm, tested pre- and post-cycling intervention.

Healthy male participants (n=16) performed a graded exercise test on a cycle ergometer to establish their peak power output (PPO). In subsequent visits, participants completed five different …

A Stress Perspective Of Leader-Follower Relationship Ambivalence, Ghada Baz

Graduate Thesis and Dissertation 2023-2024

Ambivalence is the experience of both positive and negative evaluations regarding an object such as a person or an event. Although interest in leadership ambivalence has been growing among researchers, there is still little understanding of what distinguishes it from poor leadership. The goal of this dissertation was to contribute to the leadership ambivalence literature by examining ambivalence in the leader-member exchange (LMX) relationship through the lens of occupational stress. Specifically, I used the job demands-resources model as a theoretical foundation and presented leadership ambivalence as a unique job demand that is associated with emotional exhaustion as a symptom of …

The Role Of Medical Cannabis Use In Pain, Sleep, And Mental Health Outcomes Among Older Adults, Madison H. Maynard

Graduate Thesis and Dissertation 2023-2024

Older adults represent the fastest growing demographic of cannabis users, and they endorse cannabis use for a variety of reasons including modulation of chronic pain, mental health symptoms, and sleep concerns. Despite escalating patterns of use, current evidence leaves questions of efficacy unanswered among these groups of users. Goals of the present study were to examine the role of medicinal cannabis within subjects at the daily level on the interrelated symptoms of depression, anxiety, sleep, and pain. A final sample of 106 medical cannabis users were recruited nationwide, ranging from 55 to 74 years of age (66.67% female, 82.86% white). …

Human Performance In Context: Exploring The Effect Of Social Support On Vigilance, Allison E. Garibaldi

Graduate Thesis and Dissertation 2023-2024

Over many decades, vigilance research has consistently found that performance on vigilance tasks decline over time (i.e., the vigilance decrement; Davies & Parasuraman, 1982), and that performing a vigilance task is both mentally demanding and stressful (Warm et al., 2008). Researchers have subsequently implemented a wide range of interventions to both understand and attempt to attenuate the vigilance decrement and its associated affective effects. Among these efforts, little attention has been devoted to understanding the effects of the social environment on vigilance. Nonetheless, a handful of studies have indeed suggested that the presence of others can affect performance, workload, and …

Assessment Of Caretaker Resources And Motivation In The Wean-To-Market Phase Of Swine Production, Joshua W. Holtkamp

Graduate Thesis and Dissertation 2023-2024

This study is a novel application of I/O Psychology principles to the U.S. swine industry. The Swine Health Information Center (SHIC) recently identified caretaker motivation related to compliance with biosecurity behaviors as a priority needing to be better understood. This exploratory study seeks to identify if there is indeed a worker motivation issue within the industry that is impacting compliance with biosecurity, and if so, establish both a baseline of motivation and a better understanding of the primary influencing factors. Using the Theory of Planned Behavior and the Job Demands/Resources Model of Burnout as a framework, an online survey was …

The Effects Of Sexual Assault On Identity And Interpersonal Relationships Among Male And Female Victims, Ishara Jean-Francois

Graduate Thesis and Dissertation 2023-2024

The current study aimed to examine the effect of sexual assault on identity and interpersonal relationships. Although previous studies have examined the connection between sexual assault and interpersonal relationships following assault, there is a lack of research that examines possible gender differences. Further, the effect of sexual assault on identity has been understudied. Male victims are less likely to report their assault for various reasons. Therefore, it is important to focus on this demographic so their stories and experience do not go untold, and they can get the proper help and resources. College students (N= 505) completed an anonymous online …

Patterns Of Risk Behaviors And Their Value: A Latent Class Growth Modeling Approach, Anthony Naranjo

Graduate Thesis and Dissertation 2023-2024

The current body of individual risk behavior research has been mainly driven by two streams of literature. Stable risk researchers propose individuals tend to display similar risk behaviors across time and situations due to individuals' underlying propensity to either engage in risk averse or risk seeking behaviors. Changeable risk researchers have sought out to examine variability in risk behaviors due to factors such as personality and contextual characteristics. However, might it be the case that there are subgroups of individuals who may be more prone to display static risk behaviors and other subgroup whose risk behaviors are more amendable? To …

Revisiting The Vigilance Taxonomy: Are Findings Consistent In A Remote Environment?, Grace E. Waldfogle

Graduate Thesis and Dissertation 2023-2024

Previous research has highlighted key taxonomic factors that have been found to influence human performance on vigilance tasks. However, previous literature has focused on research conducted in laboratory settings but has not examined vigilance tasks in remote environments. The present dissertation addresses this gap in the literature by examining human performance on a remote vigilance task, as well as workload and stress associated with the task. Qualitative data were collected to further understand the environment and distractions that participants experienced. Across three experiments, 372 participants were asked to complete a vigilance task and answer surveys pertaining to stress, workload, and …

Body-Image Distress In Breast Cancer Survivors And Their Evaluation Of Medical Tattooing Following Surgery, Miranda Proctor

Graduate Thesis and Dissertation 2023-2024

A review of the literature reveals a high incidence of body-image distress among breast cancer survivors who have undergone surgery, which is a natural response to the significant changes in their appearance. Reconstructive surgery, utilizing implants or flaps, may be employed to restore breast size and shape. Medical tattooing can simulate the nipple-areola complex and decorative appliques can conceal scars and skin color variations. Both reconstructive surgery and medical tattoos are associated with patient-reported satisfaction, yet further research is necessary to understand their combined impact on body-image distress. To investigate this, a survey was distributed among national breast cancer support …
