A Multi-Case Study Exploring Ncaa Division I Athletic Departments’ Mental Health Culture Through Stakeholders’ Perspectives, Kimberly Ann Granados Tolentino

Graduate Theses, Dissertations, and Problem Reports (ETD)

Despite the NCAA’s ongoing efforts to guide athletic departments into providing sufficient mental health support to student-athletes, psychological well-being continues to be a primary area of concern for collegiate athletes. Student-athletes are as likely as the regular college population to experience mental health issues, but less likely to seek services (Watson, 2005). Researchers have continued to examine the perceived barriers preventing student-athletes from utilization of mental health services which include a lack of knowledge, limited access, and perceived negative stigma (e.g., Harris & Maher, 2023; Yoon & Petrie, 2023). Organizational culture–loosely defined as a group’s accumulated shared learning in which …

Influence Of Deck Area And Average Daily Traffic On The Deterioration Of Bridge Superstructures., Faysal Ahamed

Graduate Theses, Dissertations, and Problem Reports (ETD)

State Departments of Transportation (DOTs) are responsible for maintaining approximately 623,000 bridges across the United States. Effective bridge management requires a comprehensive understanding of the factors influencing structural deterioration. Numerous studies have explored the effects of average daily traffic (ADT) and deck area (DA) on bridge deck deterioration. Given the interdependence between bridge decks and superstructures, it is plausible that ADT and DA significantly influence superstructure condition ratings and deterioration trends. However, their impact on superstructures remains insufficiently studied. In addition, existing studies primarily focus on overall bridge deterioration without adequately differentiating between superstructure designs and materials and maintenance authorities. …

Determination Of Spatial Origin Of Striations On Fired Projectiles, Kaitlin A. Dolan

Graduate Theses, Dissertations, and Problem Reports (ETD)

Firearms examination has been a mainstay of Forensic Science for over a century. One of the principal assessments performed by firearm examiners is the comparison of fired projectiles to a suspect firearm. The AFTE theory of identification, as it pertains to firearms and toolmarks, supports the basis that the barrel of a firearm will impart class and individualizing characteristics onto the fired projectile. The characteristics are developed by the interaction of the projectile surface with the lands of the barrel. Features on the lands, which are incidental to the process of manufacturing, dictate the characteristics observed on the fired projectile. …

Discovering Appalachia As A Political Place: The Influence Of Appalachian Residence And Identification On Presidential Approval And Environmental Policy Preferences, Michael Bancroft Jones

Graduate Theses, Dissertations, and Problem Reports (ETD)

From poets to political scientists, yearning for a sense of place has motivated both song and research. Appalachia is an understudied place in political science, with previous research inconclusive as to whether the Appalachian region has a separate identity from other parts of the United States (White 2019). Identities may be derived from a sense a place. Alternatively, identities may develop from a sense of group identification with common interests and grievances, and concerns regarding out-group members. Appalachia has a long history of being different and set apart from the United States; and also, has been subjected to identity mobilization …

Extinction Bursts Reexamined: The Role Of Consummatory Time And Response Reallocation, Braden Toler

Graduate Theses, Dissertations, and Problem Reports (ETD)

Two experiments were conducted to examine how the removal of the opportunity to consume reinforcement and the reallocation of that time might account for extinction bursts during within-session transitions from FR 1 to extinction. In Experiment 1, rats and pigeons were trained under FR 1 schedules and subsequently exposed to within-session extinction. Total counts of responses suggested that extinction bursts occurred for each subject, but when adjusted to exclude responses that would have overlapped with food consumption, no bursts were observed. In Experiment 2, pigeons experienced four extinction arrangements: conventional extinction, response-independent reinforcement, conditioned reinforcement, and differential reinforcement of alternative …

Risk Factors And Fraud Loss Magnitude: Informing Anti-Fraud Strategies, Robert Elias

Graduate Theses, Dissertations, and Problem Reports (ETD)

Fraud research posits risk factors may be utilized to identify individuals who are predisposed to perpetrate fraud (ACFE 2024). I find perpetrators who exhibit the following risk factors result in statistically higher fraud losses: living beyond their means, excessive pressure to perform within the organization, having excessive control issues regarding their job, are reluctant to take vacations, have a “wheeler-dealer” attitude, or addiction problems. I further find perpetrators who exhibit risk factors which are likely to be observed in a work setting are more likely to result in higher fraud losses. However, perpetrators who exhibit risk factors which are more …

Approaches To The Synthesis Of Highly Substituted Arenes, Kh Tanvir Ahmed

Graduate Theses, Dissertations, and Problem Reports (ETD)

While benzene rings and their derivatives are among the most frequently encountered ring systems in natural products, pharmaceuticals, agrochemicals, dyes, and functional materials, polysubstituted arenes are relatively scarce. The analysis of FDA-approved small molecules provides valuable insights into the characteristics of successful drugs while also highlighting gaps in the availability of synthetic methods capable of efficiently accessing diverse substitution patterns on aromatic rings. Highly substituted arenes are typically synthesized through sequential modification of a pre-existing benzene core; however, this stepwise approach becomes increasingly challenging with each additional substitution. An alternative strategy involves the direct construction of benzene rings via annulation …

The Dark Tetrad And The Intention To Invest In Cryptocurrency, Amy Bauer-Sinicin

Graduate Theses, Dissertations, and Problem Reports (ETD)

The Dark Tetrad comprises four distinct negative personality traits with some overlapping qualities: narcissism, Machiavellianism, psychopathy, and sadism. Characterized as being risky and speculative, cryptocurrencies are not backed by government banks like fiat currencies, nor do they offer the same privacy when engaging in transactions.

Narcissists may view cryptocurrency investment as an opportunity to showcase their financial acumen, reinforcing their self-image. Machiavellians see the decentralized, loosely regulated market as ideal for exploiting opportunities through strategic manipulation. Psychopaths, drawn by the market’s volatility, may engage in exploitative schemes for personal gain. Sadists may find satisfaction in the power and control they …

Beyond My Control: The Role Of Sense Of Control On Cognitive Functioning And Depressive Symptoms In Older Adults, Sabine Lohmar

Graduate Theses, Dissertations, and Problem Reports (ETD)

Depression and depressive symptoms commonly coincide with mild cognitive impairment (MCI) and dementia in older adults (Ismail et al., 2017; Panza et al., 2010), with its prevalence varying based on dementia severity, diagnostic criteria, and dementia subtype (Chi et al., 2015; Ismail et al., 2017; Leung et al., 2021; Lopez et al., 2003). This relationship is hypothesized to exist for a variety of reasons, including that depressive symptoms occur as an emotional response to cognitive functioning (Bennett & Thomas, 2014; Richard et al., 2013). Emotional responses may be explained by a decline in sense of control, or the belief in …
