Effects Of Simultaneous Alarms On Resolution Heuristics, Amanda C. Allen

Psychology Theses & Dissertations

Automated signaling systems are frequently used to direct operator attention to potential hazards. Although these automated systems can lead to enhanced human performance, factors such as degraded alarm signal reliability and lack of trust can undermine the potential benefits of automation (Breznitz, 1984; Rice, 2009, Wickens & 2007). Additionally, work by Gilson, Mouloua, Graft, and McDonald (2001), as well as Keller and Rice (2009), suggest that an alarm contained within a larger array of alarms should not be evaluated individually. Due to the increasing use of multiple alarms in complex environments such as operating rooms and cockpits (Konkani, Oakley, & …

A Quantitative Study Assessing The Impact Of Financial Sector Safeguards Rules On Us Publicly Traded Companies' Cybersecurity Breach Frequency And Severity, Alan Dinerman

School of Public Service Theses & Dissertations

Cybersecurity failure in the private sector is a growing federal policy priority. Nevertheless, US policy makers struggle with policy instrumentation in this domain. Behavioral public policy theory asserts that a linkage exists between policy target behavioral & cultural attributes and effective policy tool instrumentation. The federal government is now embracing a regulation heavy approach, but little empirical study exists at the nexus of behavioral public policy theory and use of regulatory tools in the cybersecurity policy domain. Since the early 2000s, the financial sector has employed a regulation heavy approach using the Safeguards regulations to facilitate cybersecurity in financial private …

An Examination Of Food And Alcohol Disturbance Based On Sexual Orientation In A Sample Of Women Who Binge Eat, Alicia M. Moulder

Psychology Theses & Dissertations

Food and alcohol disturbance (FAD), characterized by disordered eating behaviors in the context of drinking alcohol to enhance intoxication, counteract alcohol’s calories, or both, is associated with increased risk of negative drinking consequences. Previously established as a phenomenon occurring in college students, research has begun to support that FAD may also occur in nonstudents. Three particularly vulnerable groups for FAD may include women, individuals with history of binge eating, as well as sexual minority individuals. Consequently, the goals of the current study were to elucidate differences in FAD engagement between sexual minority women (SMW) and heterosexual women using a sample …

Short-Semester Courses: Mitigating Unfavorable Precollege Issues For Students At A Technical College, James T. Moore Jr.

Educational Leadership & Workforce Development Theses & Dissertations

Technical colleges serve a distinct student population and provide an open access point to higher education for students not wishing to attend a university. Graduation and retention rates continue to demonstrate a gap between what technical colleges wish to achieve and the actual achievement. Technical college leaders continue to embrace policies and programs intended to support students at university system schools and which poorly serve the needs of technical college students. As a result, little is known about the lived experiences of technical college students. Data were collected through a six individual semi-structured interview. The six participants of the study …

Competing In The Stress Olympics: Mid-Level Managers And Their Experiences Of Work Stress As Impacted By Their Supervisors And Organizational Climate, Melissa Jane Hecker Scott

Educational Leadership & Workforce Development Theses & Dissertations

Student affairs has a problem due to staff attrition (Rosser & Javinar, 2003). Most professionals leave the field due to job dissatisfaction, unhealthy work environments, high stress, and low morale (Marshall et al., 2016; Rosser & Javinar, 2003). Researchers have identified a relationship between job stress and burnout and intentions to leave the field of student affairs (Mullen et al., 2018). Turnover of positions is financially detrimental to the institution due to the cost of recruitment, hiring, and training the replacement employee (Agovino, 2019). In addition to the financial impact, when mid-level managers leave, there is a loss of institutional …

"Every Direction We Turn, It’S A Wall”: North Carolina School Counselors And Their Advocacy And Support For Undocumented Students’ Access To Higher Education, Wendy Eberhart Cook

Educational Leadership & Workforce Development Theses & Dissertations

High school counselors in North Carolina assist with post-secondary planning for all their students, including the approximately 3,000 undocumented students who graduate from North Carolina schools each year (Zong & Batalova, 2019). Access to post-secondary education is difficult to attain for undocumented students (Groce & Johnson, 2021), especially true for undocumented students in North Carolina, a state considered hostile to this student population due to tuition and financial aid policy (Mansfield & Hernandez, 2024). Undocumented students also face a fear of deportation, food insecurity, lower socioeconomic conditions, and language barriers (Abrego, 2006).

Despite the many barriers undocumented students face, school …

The Role Of Policy Entrepreneurs In Understanding Oral Health Care Policy: A Case Study Approach Analyzing Multiple Streams Framework In Nc Oral Health Policy, Lori Gordon Hendrick

School of Public Service Theses & Dissertations

The United States Surgeon General has defined oral diseases as a “silent epidemic” that affects the most vulnerable citizens. More often, this includes those from low socio-economic backgrounds, children, elderly, and many members of ethnic minority groups. Although preventative and treatment modalities have improved over the past fifty years, some Americans continue to have little to no access to educational and preventative programs. The lack of access to dental care for all ages and oral health care literacy remains one of the largest health concerns for American citizens making it a “wicked problem”. Historically, raising Medicaid enrollment has failed to …

Investigating The Effects Of Empathy On Implicit Race Bias, Macy Kisiel

Psychology Theses & Dissertations

Over the years there have been changes to social norms, which now discourage expressions of prejudice, and changes in many people’s self-reported attitudes, but prejudice is still a major issue in present-day American society. One important step toward addressing prejudice and social injustices is to understand the psychological processes that underlie and strengthen them. The current study aimed to use an empathy passage to positively prime the schema about a minority person of color and manipulate regulation of implicit bias. The study utilized a mixed 2 × 2 design. Sixty-four participants (Mage = 20.88 years, SD = 4.75 years) were …

Pedestrian-Motorist Self-Reported Behavioral Intentions Toward Using Alternative And Standard Safety Infrastructure, Emma Sunshine Hood

Psychology Theses & Dissertations

The increasing trend in pedestrian-motorist incidents on American roadways warrants a novel solution for improving roadway safety. Alternative crosswalk designs have piqued communities both in the United States and abroad. Designs range from slight changes in colors to extravagant illusions of the roadway falling beneath users. These crosswalk designs are not novel, literature on their efficacy as safety infrastructure is modest with mixed results. The purpose of the study was to expand the current literature on alternative crosswalk designs. The author hypothesized that the differences in behavioral intentions at alternative and standard safety infrastructure would be greater for younger male …

A Theoretical Framework For Resilience In Complex System Governance (Csg), Susan A. Caskey

Engineering Management & Systems Engineering Theses & Dissertations

This dissertation addresses a critical gap in resilience research within complex systems by developing a theoretical framework for governance resilience—an underexplored area despite governance's crucial role in maintaining system resilience. Using the Complex System Governance (CSG) framework (Keating, Katina, Chesterman, et al., 2022; Keating & Katina, 2019), resilience is conceptualized as a system's ability to absorb disturbances while sustaining performance and enabling adaptive transformation. This involves three main capabilities: persistence, adaptability, and transformation in response to both internal and external pressures.

Through a constructivist grounded theory approach involving iterative coding, memoing, and theory development, this study inductively constructs a governance …

A Self Consistent 2d Simulation Of Coherent Synchrotron Radiation Effects On Beam Dynamics, Dallan Duffin

Physics Theses & Dissertations

An increasing interest in high quality and high current electron beams necessitates a thorough understanding and prediction of coherent synchrotron radiation effects. The self-interaction of charged particles in a beam undergoing synchrotron motion is a physically significant process that is all too often computationally intensive with very little analytical results to rely on for the general case. The coherent spectrum of this interaction is of utmost importance to the design of free electron lasers (FELs) and an accurate assessment is imperative for their design. This work presents a novel implementation to the numerical simulation of charged particle beams. The simulation …
