The Virginia Academy Of Science: A Scholarly Forum Over Decades For Students Of A Plant Ecologist, Stewart Ware

Virginia Journal of Science

As a newcomer to Virginia in 1968, I learned that annual meetings of the Virginia Academy of Science (VAS) were regarded as an excellent place for students to have their first experience giving a talk about their research to fellow scientists, and a place for faculty to get to know other Virginia scientists in their fields. Over the next four decades William and Mary students (undergraduate and graduate) and I were presenters or co-authors of 42 talks or posters at VAS annual meetings, 29 of them based on studies of plant ecology across Virginia. Two were talks by colleagues with …

How Changing Majors Impacts Academic Performance Among Undergraduate Students, Min Xu, Chandra R. De Silva

History Faculty Publications

This study investigates changing majors among undergraduate students. Through retrospectively tracking five graduating classes at a regional research university, the study provides empirical evidence as to when students declare their major, reach their final decisions about a major, and explores when it would be too late to change a major in order to graduate in a timely fashion. The study also examines the relationship between changing majors and academic performance. The results which suggest the need to provide students, especially freshmen with early proactive assistance in major selection might address concerns of parents and students about choosing a college major …

More Than Representation Heartstopper: A Multimodal Critical Discourse Analysis, Tracyann Josephine Harmer

Communication & Theatre Arts Theses

This thesis is a multimodal critical discourse analysis of Netflix’s Heartstopper, written with the goal of understanding its methods of representation and queer world creation. Through analysis of the ideology of heteronormativity as it relates to masculinity, internalized homophobia, homophobia, and mental health, I expand upon the significance of queer representation for queer audiences, heterosexual audiences, and producers of queer media. Through a nuanced analysis of these themes, I display how and why Heartstopper has had enormous success and expand upon the cultural phenomena surrounding this media. Finally, this thesis places these nuanced analyses into the real-world reaction to …

Wellness As A Predictor Of Turnover Intention In The Active Duty Military, Thomas Clifford Seguin

Counseling & Human Services Theses & Dissertations

Due to the unique nature of military service compared to civilian professions, military attrition is difficult to predict using methods derived from career development theories, so turnover remains an ongoing concern for the active duty military. For this reason, military attrition, through turnover intention, should be investigated through a novel lens with the intention of capturing an essence of military service which previous methods may have overlooked, namely the holistic construct of perceived wellness. Previous studies have shown how wellness-related factors affect turnover intention, but none has studied the relationship between perceived wellness and turnover intention. The main hypothesis of …

Autism At Work Across The Career Span: A Scoping Review, Kate Noel Warnock

Psychology Theses & Dissertations

This scoping review takes a career-span approach to the experiences of autistic people at work. Using Super’s (1994) life-span, life-space theory as a framework, I divided the literature into five career phases: Growth, Exploration, Establishment, Maintenance, and Disengagement. In each phase, I reviewed the challenges and facilitators that autistic people face, highlighting themes that have strong support in the literature, and areas that need further examination in future research. Additionally, I argue that Super’s career framework is not the most parsimonious way to describe the career trajectories of autistic individuals and propose modifications to the framework to better represent their …

Visual Attention In Remote Vehicle Supervision: Examining The Effects Of Mental Models And Information Bandwidth, Michael Stanley Politowicz

Psychology Theses & Dissertations

Advances in automation and aviation technologies have been catalysts for the emerging market of Advanced Air Mobility (AAM), an ecosystem of novel aircraft concepts including package delivery drones and passenger carrying air-taxis. Future aircraft operators in this environment will be tasked with remotely supervising multiple highly automated aircraft on a visual interface while receiving less training than traditional pilots. More research should explore how an operator’s potentially limited understanding of an automated system affects visual performance and interactions between human operators and AAM technologies. This study examined the influence of mental models of an autopilot system on visual attention allocation …

Public Service Motivation And Volunteer Firefighters In Rural Environments, Terina Chapin Brooms

School of Public Service Theses & Dissertations

Volunteer firefighters serve their communities by offering life and property protection without compensation. With over 700 million volunteer firefighters in the United States, this population remains largely underrepresented in the public administration literature along with understanding public service motivation (PSM) in protective service industries. Using a sample of South Dakota volunteer firefighters, the study tested the applicability of PSM across a volunteer-based public service, the volunteer fire service. Through factor analysis, a viable PSM measure was confirmed across the sample consisting of the self-sacrifice and commitment to public interest dimensions. Compassion was notably unable to be confirmed as a dimension …

Trust And Contexts: A Conceptual Framework For Understanding Coastal Household Preparedness, Ogechukwu M. Agim Nwandu-Vincent

School of Public Service Theses & Dissertations

Despite research findings that show the benefits of being prepared for increasingly tumultuous natural and coastal hazard events, studies on hazard preparedness indicate that low levels of preparedness may occur in vulnerable areas due to the uncertainty around hazard risks, expected hazard onset and impact strength, as well as associated effects. Study findings indicate that trust may impact the uncertainty and complexity faced by people dealing with unfamiliar, infrequent, and complex hazards, as well as contexts such as factors such as age, gender, prior hazard experience, and homeownership.

While studies have looked at the relationship between trust and compliance (desired …

Effects Of Balance Training On Spinal Reflexive Excitability Modulation, Corticospinal Excitability, And Balance Performance In Individuals With Chronic Ankle Instability, Sunghoon Chung

Rehabilitation Sciences Theses & Dissertations

Chronic ankle instability (CAI) is a neurophysiologic deficit resulting in diverse sensorimotor impairments. Following acute ankle sprains, pain, mechanical instability, and joint deafferentation reduce sensory input to the central nervous system (CNS). In response, the CNS sends altered motor signals to lower extremity muscles. These CNS changes contribute to various neuromuscular impairments in CAI patients, the most common of which is reduced balance performance. Specifically, CAI patients struggle to modulate spinal reflex excitability of the soleus muscle when progressing from simpler to more complex balance tasks. This overreliance on spinal reflexes results in inconsistent activation of the ankle stabilizing muscle. …

3/5ths Of Freedom: The Analysis Of {With} Black Individuals In Higher Education And Navigating Society Post-Justice-Involvement, Gabrielle Sarah Smith Finnie

Educational Leadership & Workforce Development Theses & Dissertations

Black individuals have been disproportionately involved in the criminal justice system in the United States (Federal Bureau of Prisons, 2022). Because of their criminal justice involvement, Black individuals are perceived as second-class citizens making their quest for “freedom” an endless journey impacted by oppression and domination post-justice-involvement (Couloute & Kopf, 2018; Johnson, 2021; Pager, 2003). To combat domination and oppression, Freire (1970) emphasized pursuing higher education helps individuals who experience marginalization become more humanized and aids them on their plight to freedom. Research highlighted pursuing higher education post-justice-involvement is a liberatory yet challenging experience because of discriminatory on-campus …

The Experiences Of Multilingual Learning-Focused School Counselors: A Phenomenological Investigation, Chelsea Jo Hilliard

Counseling & Human Services Theses & Dissertations

Overall, while the research on school counselors serving MLL students (at the pre-service and practice level) …

First-Generation College Students And Sense Of Belonging At School: The Moderating Effect Of Remote Learning, Christina Su Ju

Psychology Theses & Dissertations

This study examines the effect of first-generation college student status on students’ sense of belonging, and whether remote learning moderates this effect. Specifically, this study examines whether first-generation college students’ sense of belonging at university differs from their continuing-generation college student counterpart, and whether taking remote courses impacts that relationship. It was hypothesized that first-generation college students would report lower sense of belonging than continuing-generation college students, and that remote learning would moderate the relationship such that the negative effect of first-generation student status on sense of belonging is strengthened when the student takes more remote courses. Survey data from …

Understanding The Impact Of Emergent Conflict On Communication And Team Cognition: A Multilevel Study In Engineering Teams, Francisco Cima

Climbing The Academic Ladder While Black: Exploring The Experiences Of Institutional Belongingness For Black Counselor Education And Supervision Doctoral Students At Predominantly White Institutions, Jasmine Alicia Hawa Griffith

Counseling & Human Services Theses & Dissertations

Although ample research investigates students’ belongingness experiences in counselor education (CE) programs, existing literature only marginally explores the realities of Black master students, and there is a notable lack of empirical attention to Black doctoral students’ belongingness experiences in counselor education and supervision (CES) programs. Investigating Black CES doctoral students' belongingness experiences at Predominantly White Institutions (PWIs) is critical to understanding how the Council for Accreditation of Counseling and Related Education Programs (CACREP) accredited CES programs can address the troubling statistic that Black doctoral students are least likely to become full-time CE faculty. Consequently, this study utilizes critical phenomenology from …

Compassionate Communication, Social Support, And Safety: Needs Of People Experiencing Homelessness, Emma Lynn Jackson

Communication & Theatre Arts Theses

On any given night in 2023, approximately 650,000 people were experiencing homelessness (HUD, 2023). With the highest rate of homelessness since national reporting began in 2007 and double the rate of chronic homelessness since 2016, it could be inferred that the resources are not effectively mitigating the problem (HUD, 2023). To attempt to understand this complex issue, this thesis initially reviewed theories on societal structures, personal connections, social support, and gaps in support. In person interviews of 14 people living with homelessness explored perceptions of support, social challenges, involvement in the community and lack of support. Following each interview, a …

Innocence Through An Intersectional Lens: An Examination Of Women And Wrongful Convictions, Briana Paige

Sociology & Criminal Justice Theses & Dissertations

According to The National Registry of Exonerations (2022), nearly 40% of all exonerations involve a no-crime wrongful conviction. While women make up less than 10% of all exonerees, nearly 73% of exonerated women were originally convicted of crimes that never happened, compared to only 38% of exonerated men. Despite their prevalence, the topic of no crime wrongful convictions is extremely understudied in the wrongful conviction literature.

Additionally, since prior research on wrongful convictions has been primarily male centered, the likelihood that a woman’s case will be accepted to be reviewed for innocence is significantly lower than men (Free and Ruesink, …

Understanding The Role Of Adverse Childhood Experiences On Resilience In Police Officers, Wayne F. Handley

Counseling & Human Services Theses & Dissertations

Police officers are subject to a variety of stressors not only from job-related events resulting from direct or vicarious trauma exposure (Andersen & Papazoglou, 2014; Brown et al., 1999; Iversen et al., 2008) but also from family and personal concerns (Burke, 1998; Page & Jacobs, 2011), and administrative pressures originating from within their own agencies (Violanti et al., 2018; White et al., 2016). Prior to their careers as police officers, individuals may also be exposed to traumatic events early in life. Adverse Childhood Experiences (ACEs) are described as negative events related to emotional, physical, or sexual abuse or neglect, exposure …

Comparing The Effects Of Task Experience And Interruption Source On Resumption Performance, Sarah Anastazia Powers

Psychology Theses & Dissertations

The timing of an interruption can be disruptive to task performance; however, the effect of participant control over when interruptions occur is not well understood. Further, it is unclear how participants’ experience with the primary task influences when they decide to address interruptions. Utilizing a 2 (task experience, between subjects) X 3 (interruption source, within subjects) mixed design, undergraduate students who had different amounts of experience with a computer-based medication dosage calculation task completed three trials of the task: once with the experimenter scheduling interruptions to occur at coarse breakpoints within the task, once with the participants deciding when to …

Building Trust Through Allyship: Moderating Roles Of Motivation And Perspective, John Michael Savage

Psychology Theses & Dissertations

Previous research has indicated demographic differences between employees may influence relational development. To address this concern the current study examined the interpersonal influence that racial allyship has on trustworthiness. The first hypothesis was formed using social exchange theory to predict that allyship behaviors would increase perceptions of trustworthiness. Additionally, relational signaling theory was integrated to inform the second hypothesis, which predicted that self-interest motivations would attenuate the relationship between allyship and trustworthiness. To account for differences in perspective the third hypothesis predicted that race would moderate the conditional effect of self-interest motivation. Employees were recruited online to complete a questionnaire …
