The Relation Between Early Adolescent Physical Activity And Internalizing Problems: Variations In Exercise Motivations As A Critical Moderator, Stephen Taylor

Theses and Dissertations

Although research suggests there is a bidirectional relation between Physical Activity (PA) and internalizing symptomology, there are inconsistencies in the literature regarding this relation for early adolescents and little research exists that investigates potential moderators that may account for these discrepancies in underserved (i.e. low SES and minority status) populations. The current study was the first to utilize a Self-Determination Theory (SDT) framework to investigate the main effects five key motivations to exercise and their moderating effects between PA and internalizing problems in an underserved sample of early adolescents (N = 167; M age = 12.19 years; 58.1% female and …

Evangelicals, Perceived Marginalization And Expressive Mobilization, Christin E. Mcmasters

Theses and Dissertations

Expressive forms of collective and individual mobilization of the evangelical population in the United States have been understudied in both social movement theory and religion and politics literature. While these forms of mobilization are not the only form of mobilization, they are important to understanding what specific issues evangelicals are feeling aggrieved about. Current research such as Wong (2018a; 2018b) and Sides, Tesler, and Vavreck (2018) have found that there is a growing sense of racial anxiety among the ranks of white evangelicals. Hence, it is likely that evangelicals, at least white evangelicals, are feeling a sense of marginalization.

Developing A Measure Of Empowerment In Schools, Abby Albright Bode

Theses and Dissertations

Youth empowerment is widely defined as youth being actively involved in and influencing their environment in such a way as to foster positive developmental trajectories. Youth empowerment is fostered by such external aspects as positive relationships with adults, having a safe and supportive environment, and being included as meaningful contributors to teams. Given these aspects that enhance empowerment, schools are poised to provide a natural context for fostering youth empowerment. Relatedly, there is a national movement toward more comprehensive school mental health (SMH) programs and services, and building youth empowerment within this field is a logical and needed step, but …

Anthropogenic Influences On Sedimentation In The Chicken Creek Watershed Of South Carolina, Tyler L. Dearman

Theses and Dissertations

Anthropogeomorphic changes in response to destructive agricultural practices followed the arrival of European settlers into the Americas. The southeastern Piedmont physiographic region of the USA was severely affected by erosion and sedimentation following settlement in the 1700s and farming up through the 1930s. Deep floodplain aggradation formed uninterrupted alluvial deposits that extended many km. This research examines anthropogenic impacts of land-use change on valley bottom sedimentation in the Chicken Creek Watershed of South Carolina. Abrupt contacts between pre-settlement floodplain soils and a thick overburden of legacy sediment are common throughout the two-km study reach and provide clear evidence of extensive …

Rural Public Library Assets And Socioeconomic Demographics: A Multi-Classification Study, Karen A. Miller

Theses and Dissertations

Rural public libraries hold economic, cultural, and social capital assets in trust for the benefit of their communities. Filling a gap in the study of those assets, 2012 through 2015 rural library statistics from the Institute of Museum and Library Services were combined with public data from the United States Departments of Agriculture and Health and Human Services to: (1) reveal interrelationships between rural public library assets and socioeconomic factors, (2) explore the implications of those relationships in terms of potential community services and asset strengths, (3) investigate differences in those relationships over time, and (4) consider rural library asset …

The Readiness Monitoring Tool: Investigating The Psychometric Evidence For Group-Level Aggregation In Two Samples, Samantha N. Hartley

Theses and Dissertations

Organizational readiness is an essential factor for successful implementation of a particular innovation. Although there is general consensus within the research literature on the importance of organizational readiness, there has been significantly less agreement on the nature of readiness as a construct and how it should be operationalized. Previous research has focused on organizational readiness for change at both the individual and organizational levels, but measures based on these theories of readiness have typically lacked evidence of reliability and validity.

The R=MC2 heuristic and its associated measure, the Readiness Monitoring Tool (RMT), offer a compelling and comprehensive approach by which …

Gene By Environment Interaction On Weight-Related Outcomes Over Time In Underserved African-American Adults, Tyler Coe Mcdaniel

Theses and Dissertations

Obesity research in the area of prevention has become a national priority given the increasingly high prevalence rate of this condition among US adults, and subsequent health risks that are associated. The etiology of obesity is complex, so a more comprehensive understanding of the interaction between genetic predisposition and the social environment in regards to obesity in adults would advance our knowledge for future public health and prevention efforts. This study’s aim was to assess the impact of a gene by neighborhood social environment interactions on weight-related (i.e., waist circumference) and stress-related (i.e. cortisol) outcomes in underserved African-American adults. A …

Life Satisfaction In Adolescents With High-Functioning Autism Spectrum Disorder, Kathleen Blackburn Franke

Theses and Dissertations

The present study was informed by the Emerging Disability Paradigm, which emphasizes the importance of research regarding positive experiences, personality, and social relationships for individuals with disabilities (Schalock, 2004). The purpose of this study was to provide preliminary evidence regarding the reliability and validity of measures of self-reported psychosocial assets and life satisfaction (LS) for adolescents with high-functioning autism spectrum disorder (HFA). Additional purposes included identifying the overall levels of general and domain-specific LS within adolescents with HFA, comparing these levels to those of a sample of typically developing adolescents, and describing the relation between psychosocial assets and LS for …

Family Oriented Values, Emerging Adulthood, And Tobacco Use Among Hispanic Emerging Adults, Melek Yildiz Spinel

Theses and Dissertations

Theory and research on emerging adulthood (ages 18 to 25) have increased in the past two decades. However, few studies have assessed how different cultural values and experiences influence the experiences of ethnic minority emerging adults. The first objective of the current study was to expand the field of emerging adulthood research by exploring how familism, the belief that family is central to a person’s life, related to their experience of emerging adulthood. Specifically, the study assessed how familism related to Arnett’s proposed experiences of emerging adulthood (identity exploration, self focused, other-focused, feeling in between, the age of instability/negativity, and …

Internal Gravity Wave Detection During The 21 August 2017 Total Solar Eclipse, Michael J.W. Stewart

Theses and Dissertations

Total solar eclipses supply both visual captivation and a controlled meteorological experiment through a sudden decrease in solar radiation. However, along with commonly expected changes in weather conditions, prior research suggests an adjustment of atmospheric dynamics caused by both a decrease in local incident solar radiation and the Moon’s sweeping shadow across the Earth at supersonic speed. The result is the potential production of internal gravity waves, which transfer both energy and momentum vertically to and from the upper levels of the atmosphere. A series of radiosondes were launched before, during, and after the 21 August 2017 eclipse in Batesburg, …

Analysis Of Evacuation Behaviors And Departure Timing For October 2016’S Hurricane Matthew, Erika O. Pham

Theses and Dissertations

During a hurricane, an individual’s risk perception does not remain static. Spatial and temporal variations of a hurricane will shift perceptions of risk, and complicating this dynamic are information-seeking processes increasingly reliant on the individual’s self-motivated interpretation of information sources. Initial evacuation resistance or willingness could change even after evacuations are ordered, affecting evacuation preferences and departure times. Because Hurricane Matthew’s continually shifting track had virtually nonstop coverage, evacuation decisions were also being modified as residents either grew more or less certain of their safety.

This research investigates the evacuation behaviors associated with Hurricane Matthew in October of 2016. It …

Reevaluating The Parenting Wellbeing Gap: Evidence From The Wellbeing Module Of The American Time Use Survey, Daniela Veronica Negraia

Theses and Dissertations

Both scholars and the public have been intrigued by the question of whether parents experience higher levels of emotional wellbeing than adults who are not raising children. Yet despite decades of research on the topic, the answer to this question remains unclear. Using a novel source of nationally representative data, the Wellbeing Module of the American Time Use Survey (2010, 2012, 2013), this dissertation aims to unpack and extend prior understanding of the parenting wellbeing gap by pursing two studies. The first investigates whether parenthood may have both positive and negative links to adults’ emotional wellbeing; whether the gap varies …

Cognitive Remediation Of Working Memory Deficits In Children With Chronic Health Conditions: Tailoring Cogmed Training To Address Barriers To Adherence, Kelsey Smith

Theses and Dissertations

Objective: Children with sickle cell disease (SCD) and cancer are at risk for working memory impairment due to the disease and treatment. However, inconsistency in adherence to cognitive training programs conducted with this population suggests that adaptations are necessary in order to improve the effectiveness of this intervention. In addition, it is unclear whether gains in working memory translate to improvement in classroom functioning.

Methods: Children engaged in cognitive training exclusively over the summer in order to improve adherence to Cogmed Working Memory Training. A total of 17 children ages 7- 17 with a diagnosis of SCD (n = 14) …

Fandom In Politics: Scale Development And Validation, Won-Ki Moon

Theses and Dissertations

Despite the importance of fandom in politics to understanding individuals’ political behaviors, reliable scales measuring political fandom are lacking. To fill this gap, the present study constructs and validates a new scale for political fandom. First, by reforming existed questions and making new questions, the author derived 42 questions belonging to seven dimensions as an initial item pool based on conceptualization. Second, to refine and develop the scale, the researcher conducted exploratory factor analysis and confirmatory factor analysis. According to the result of the studies, the final factor model of political fandom retained 25 questions and seven dimensions. In addition, …

The study addresses the general lack of scholarship focusing on web designers, and helps build an understanding of the processes and forces that govern the development and creation of websites. The findings of …

That Diabolical Traffic: Archaeological Explorations Of The Nineteenth Century Slave Trade In Coastal Guinea, Katherine Goldberg

Theses and Dissertations

The nineteenth century transatlantic slave trade had significant social, political, and economic ramifications for the coastal West African environments. As Britain pressured European and American imperial powers to join in anti-slave trading endeavors in the early portion of the nineteenth century, the slave trade was directed to areas such as the Rio Pongo in coastal Guinea, where imperial and national powers were scarce, and both legal and contraband trade could continue to succeed. In these situations, foreign traders were able to integrate themselves into local networks, gaining access to social and material capital, and creating a new class of transnational …

Three Essays On Maternal And Child Health, Mandar V. Bodas

Theses and Dissertations

This dissertation is a collection of three separate essays on the health of women and children. In the first essay, I along with my co-authors, analyzed the impact of two large, national-level health policies (the Janani Suraksha Yojana (JSY) and the National Rural Health Mission (NRHM)) on maternal health outcomes (proportion of institutional deliveries) in India. We used data from the India Human Development Survey (IHDS) and found that the JSY and the NRHM had a greater impact on institutional deliveries in high-focus states. We also found that the conditions of the public health facilities, did not change after the …

Investigating Racial Bias In Perceptions Of Free Will, Courtney J. Alderson

Theses and Dissertations

The overarching goal of this study was to examine whether perceptions of others’ free will would differ depending on perceiver race as well as target race. The current study proposed that such a racial bias may be one mechanism by which racial disparities in medical treatment recommendations arise. By bridging findings from four different lines of research (i.e., the literatures on racial health and medical treatment disparities, racial bias, free will beliefs, and social identity), it was hypothesized that: (1) participants would perceive greater amounts of free will for a hypothetical racial ingroup patient than an outgroup patient; (2) such …

Why Local Governments Collaborate: Perspectives From Elected Officials And Local Government Managers On Regional Collaboration, Stephanie D. Davis

Theses and Dissertations

This study examined the factors that influence a local government’s decision to engage in regional collaborations. Analysis of 7 local government managers and eleven elected officials revealed that the decision to engage in regional collaboration was influenced by external factors, organizational factors, and internal motivations. Elected officials and local government managers identified a disaster occurrence, fiscal stress, outside agencies, jurisdictional benefit, and communication as key factors. Further, this research highlights the importance of the role of the elected official in intergovernmental arrangements, the role of the local government manager as the policy entrepreneur, and the influence of shared norms and …

Differences In Spatial Visualization Ability And Vividness Of Spatial Imagery Between People With And Without Aphantasia, Anita Crowder

Theses and Dissertations

Mathematics education researchers have examined the relationship between visualization and mathematics for decades (e.g., Arcavi, 2003; Bishop, 1991; Duval, 1999; Fennema & Tartre, 1985; Presmeg, 1986). Studies have linked spatial visualization ability, such as measured in mental rotation tasks, directly to mathematics self-efficacy (Pajares & Kranzler, 1995; Weckbacher & Okamoto, 2014), which in turn influences mathematics achievement (Casey, Nuttall, & Pezaris, 1997). With the important role that spatial visualization plays in learning mathematics, the recent identification of congenital aphantasia (Zeman, Dewar, & Della Sala, 2015), which is the lack of mental imagery ability, has raised new questions for mathematics education …

Prosecution As The "Soul Crushing Job:" Complexities Of Campus Sexual Assault Cases, Tammi L. Slovinsky

Theses and Dissertations

On April 4, 2011, the U.S. Department of Education issued a Dear Colleague Letter on campus sexual assault reaffirming the intent of Title IX, the 1972 law that prohibits discrimination sex-based under any education program or activity receiving federal financial assistance. In response to growing concern over due process rights for defendants, in September 2017 the guidance was rescinded. Public policy continues to evolve, leading to potentially lasting institutional changes on many college campuses. These developments include the formalization of campus investigations and adjudications, the development of campus coordinating committees and expanded support mechanisms for victims. In Virginia, laws passed …

Communicating Colorectal Cancer Risk To Average Risk Adults: Examining The Impact On Risk Perceptions And Health Behavior Intentions, Carrie A. Miller

Theses and Dissertations

Background. CRC risk can be reduced though lifestyle modification and regular screenings. Providing CRC risk feedback that promotes preventive behaviors to those at average risk has the potential to significantly reduce CRC morbidity and mortality.

Purpose. The purpose of this dissertation was to examine the impact of CRC risk assessment feedback among adults aged 50-75 with no personal or family history of the disease. The specific aims were to: (1a) test personalized (vs. generic) risk assessment feedback on individuals’ risk perceptions and intentions to engage in three risk-reducing behaviors (e.g., physical activity, diet, and screening); (1b) determine if the provision …

Validation Of Virginia's Juvenile Risk Assessment Instrument, Jessica P. Schneider

Theses and Dissertations

Utilizing a validated risk assessment tool to predict future offending is recommended as best practices in corrections by a number of professional organizations (Latessa & Lovins, 2010). Guided by the risk-needs-responsivity model, risk assessment tools have evolved to help inform criminal justice practitioners by identifying offenders most in need of intervention or supervision, guiding the case plan to optimize outcomes (Bonta & Andrews, 2007). The Virginia Department of Juvenile Justice (DJJ) utilizes the Youth Assessment and Screening Instrument (YASI) at all stages of contact with youthful offenders, including intake, probation, commitment, and parole (DJJ, 2016). However, risk assessment instruments do …

The Experiences That Promote Success For Students With Intellectual Disability In Postsecondary Education, Kimberly S. Handsome

Theses and Dissertations

This in-depth qualitative, phenomenological (Smith & Fowler, 2009) research study attempted to understand the experiences of young adults with intellectual disability who had completed a 2-year, inclusive postsecondary education program. 13 participants (4 former students with ID, 5 parents, and 4 Postsecondary Education staff members) participated in semi-structured interviews. Interviews were coded to provide themes amongst each individual group of participants. A document review was also conducted to better understand the program components and add validity to self-reports from interviews. Results were analyzed and used to provide implications for future research and program development.

Police Officer Perceptions Of Organizational Justice And Body-Worn Cameras: A Civilizing Effect?, Carolyn Naoroz Ph.D.

This research sought to understand the potential association between officer perceptions of organizational justiceand officer perceptions of body-worn cameras (BWCs). A questionnaire was administered to a convenience sample of 362 officersfrom the 750 sworn personnel from the Richmond Police Department in Richmond, VA, yielding a response rate of 91% and representing 44% of the Richmond Police Department’s sworn employees. This study extends prior work by partially replicating a previous BWC survey conducted by leading body-worn camera scholars, utilizing a large sample from an urban mid-Atlantic police department. This study also extends prior work on officer perceptions of organizational justice …

A Practice Elements-Based Approach To Adherence Measurement, Stephanie Violante

Theses and Dissertations

The measurement of treatment adherence (i.e., the frequency and thoroughness with which a therapist delivers a treatment as designed) is critical to the field of implementation science, as adherence is often considered an indicator of successful implementation. Most existing instruments of treatment adherence are treatment protocol specific; however, this approach is costly, inefficient, and disallows cross-treatment and cross-study comparisons. Thus, there is a need for adherence instruments that can be used across treatment protocols. It has been suggested that an instrument that captures adherence at the practice element level would meet this need, as it would have utility across protocols …

Tommi's Place: An Adaptation And Commentary On Uncle Tom's Cabin, Vanessa L. Jackson

Theses and Dissertations

Harriet Beecher Stowe penned Uncle Tom’s Cabin which was published in 1852. This book exposed and condemned the atrocities of slavery. Her book became a bestseller and is said to be one of the primary reasons why slavery was eventually abolished. Though slavery has been dismantled the system of oppression which allowed the marginalization of others to thrive has never been eliminated. This system established a dominant culture; one which oppresses those of African descent and has endured for centuries. Tommi’s Place retells Uncle Tom’s Cabin in contemporary corporate America. Tommi’s Place reflects that this system of oppression is still …

Structured Poetic Expressions For Emerging Adults Experiencing Bereavement, Kelcie D. Willis

Theses and Dissertations

Previous research has produced heterogeneous findings regarding the effectiveness of expressive writing in reducing grief symptomatology among the bereaved (e.g., Collison, 2016; Lichtenthal & Cruess, 2010; Stroebe et al., 2006). The purpose of this study was to address these mixed results by exploring the effects and linguistic characteristics of a novel writing task (i.e., the acrostic poem) among bereaved undergraduates, using an innovative data analysis technique (i.e., Linguistic Inquiry and Word Count). The current study recruited 68 undergraduates who had lost a loved one. Participants were randomly assigned to write over multiple days using the acrostic poem, emotional disclosure prompt, …

Evaluating And Reducing The Effects Of Misclassification In A Sequential Multiple Assignment Randomized Trial (Smart), Jun He

Theses and Dissertations

SMART designs tailor individual treatment by re-randomizing patients to subsequent therapies based on their response to initial treatment. However, the classification of patients being responders/non-responders could be inaccurate and thus lead to inappropriate treatment assignment. In a two-step SMART design, by assuming equal randomization, and equal variances of misclassified patients and correctly classified patients, we evaluated misclassification effects on mean, variance, and type I error/ power of single sequential treatment outcome (SST), dynamic treatment outcome (DTRs), and overall outcome. The results showed that misclassification could introduce bias to estimates of treatment effect in all types of outcome. Though the magnitude …
