Comparison Of Ground-To-Air Visibility Analysis Methods, Erica Pfister-Altschul

Theses and Dissertations

When a disaster occurs, remotely sensed imagery is critical for emergency responders. Aircraft collect digital images of damaged areas to assist with damage assessment and response planning. Such airborne imagery can be transmitted directly from the plane to ground antennae and internet-connected dispersal, allowing for faster acquisition of data. However, air-to-ground transmission of images requires near-constant visibility between the aircraft transmitter and ground station antenna. This research uses GIS-based models to identify the ground station locations that can reliably receive data from aircraft, using a variety of visibility analysis methods and a comparison of their performance. A custom algorithm is …

Lead Exposure And Crime, Tara Elaine Martin

Theses and Dissertations

While lead exposure during childhood has been linked to criminal activity later in life, prior research has failed to develop a theoretical foundation explaining why lead and crime rates are positively related at the aggregate level. Utilizing tract-level data, I examine the relationship among elevated blood lead level rates, levels of concentrated disadvantage, and crime rates. Through a biosocial approach, I explore the lead-crime relationship using a measure of concentrated disadvantage to account for the variations across tracts. Finally, I discuss the results of this study as well as implications for public policy and future research.

The Effect Of Winning Football And League Affiliation On Academic Achievement In The Southeastern Conference (Sec) Does Winning Football And Conference Improve Student Related Academic Indicators ?, A. Wayne Alexander Ii

Theses and Dissertations

Numerous researchers have attempted to study the effect of winning football on a university’s academic standing. To this point, the results have been varied and inconclusive. The answer is unclear and the research does not examine a conference as a whole in comparison to other conferences since the Bowl Championship Series (BCS)- era (1998-2012). The current study examines whether the Southeastern Conference (SEC) and the success of the conference’s football teams, in terms of winning games and conference membership, improves the conference's member schools academic indicators. Using factors such as SAT scores, application rate, retention rates, and graduation rates, this …

The Effects Of Political Control And Institutional Structure On State Ethics Commissions, William Jonathan Rauh

Theses and Dissertations

State ethics commissions serve as both oversight and enforcement bodies. However they are also quasi-judicial institutions whose members are appointed by elected officials. At best this presents problems of oversight, and at worst it implies that commissions can be actively influenced by the very individuals they are tasked with overseeing. Previous studies of ethics commissions have examined the covariates of creating ethics commissions, or have examined the internal functioning of these commissions in the pursuit of their envisioned goals. A largely ignored area of study with regard to these commissions is the degree to which elected officials can exercise influence …

Characterization Of The Hippocampal Acetylcholine System In A Rodent Model Of Fetal Alcohol Syndrome, Amy Elizabeth Perkins

Theses and Dissertations

Fetal alcohol spectrum disorders (FASD) are a major public health concern, as it is estimated that 2-5% of children are exposed to alcohol at some point during prenatal development. FASD have been shown to cause damage to multiple brain regions, but research shows that the hippocampus is especially sensitive to alcohol exposure. This damage to the hippocampus explains, in part, deficits in learning and memory that are hallmark symptoms of FASD. The acetylcholine neurotransmitter system plays a major role in learning and memory, and the hippocampus is one of its main targets. This experiment used a rodent model of Fetal …

Testing Bidirectional Contextual Effects Of Adolescent Risk Factors On Young Adulthood Outcomes: A Life Course Perspective To Gangs, Andrea E. Lamont

Theses and Dissertations

Leading theories in developmental science emphasize the role of the individual as an active agent in shaping her or his environment. Yet, most empirical work has focused on unidirectional models, ultimately treating the individual as a passive recipient of environmental risk. Part of this gap between theory and analysis is methodological in nature – i.e., classical statistical methods typically do not allow for the modeling of bidirectional influences or complex longitudinal relations. Recent advancements in longitudinal methodologies, however, expand our ability to answer more nuanced developmental questions. In this dissertation, I demonstrate how advanced longitudinal methods could be used to …

Parental Mediation Of Adolescent Movie Viewing, Larry James Webster Jr.

Theses and Dissertations

Parental mediation of media use by children has been studied extensively as it applies to television and children 12 years old and younger. This study expands the scope of Parental Mediation Theory by applying it to adolescents (age 13-17 years old) and movie viewing. The results of this study show overall parental mediation of adolescent movie viewing is negatively associated with the age of the child. The results show that among parents who mediate movie viewing, restrictive, instructive and social co-viewing mediation strategies are negatively correlated with the age of the adolescent. Third Person Effect is also examined as parental …

The Contribution Of Status Lineages In The Rise Of The State: A New Theory Of State Formation, Yamilette Chacon

Theses and Dissertations

In social theory, ancient societies are frequently seen as `traditional' in the sense of being static. If static, there is a problem for theory for we know that, over time, societies have evolved to become more complex. This dissertation proposes a dynamic model for the social structure of the chiefdom based in a synthesis of anthropological and experimentally grounded sociological theory. Its purpose is to explain 1) why the chiefdom is an effective social structure in that it promotes collective action and 2) why the chiefdom becomes increasingly unstable over time. Because of that instability, the chiefdom may stand at …

Military Service Members’ And Veterans’ Preferred Approach To Mental Health Services, Lisa Goldberg Looney

Theses and Dissertations

Mental health services are greatly underutilized by military service members and veterans. Among the reasons for this underutilization is that the services offered may not be a good fit for the specific problems facing service members/veterans and/or their families. The current study presented service members with descriptions of several approaches to treatment and asked them to indicate the likelihood of using each. Service members indicated the highest likelihood for using self-directed services, followed by individual treatment with a professional. They reported being least likely to use group approaches. These results may inform decisions about the implementation and dissemination of information …

Characterizing Wetland Hydrology, Chemistry, And Soils For An Endemic Crayfish, The Piedmont Blue Burrower, Jess H. Gilmer Ii

Theses and Dissertations

Anthropogenic alteration of Earth's ecosystems has pushed global biodiversity into a state of crisis. Freshwater species have been particularly vulnerable, with crayfish ranking as the second most imperiled taxonomic group in North America. Primary burrowers represent only 15% of crayfish species in North America; however, they constitute 32% of imperiled crayfish. Despite their conservation importance, little is known about the ecology of burrowing crayfish. To advance our knowledge about the habitat characteristics of burrowing crayfish, groundwater hydrology, water chemistry, and soil properties were assessed to determine their importance for the state-listed endangered, primary burrower Cambarns harti. Groundwater hydrology and …

Follow-Up Evaluation Of Treatment For Anxiety And Depression Provided In A University-Based Primary Care Clinic, Renée M. Grinnell

Theses and Dissertations

Although integrated primary care psychology services are becoming increasingly common, the literature lacks adequate research support for the longitudinal durability of treatment effects following the conclusion of brief primary care interventions. This study served as a follow-up program evaluation of psychological services for depression and anxiety provided at the Medical College of Virginia’s Ambulatory Care Center in Richmond, Virginia. Data were collected on 47 adult primary care patients who received treatment for depression and/or anxiety between six and 18 months prior to the follow-up telephone call. Data were collected on the trajectory of depression scores throughout and following treatment, treatment …

Resilience In Parkinson’S Disease: An Empirical Examination Of Age-Related Components Of The Construct, Andrea Garroway

Theses and Dissertations

Although Parkinson’s disease (PD) is commonly characterized by motor symptoms and physical limitations, there is growing recognition of nonmotor and mood symptoms associated with the disease as well. There has been limited research exploring how individual coping might affect the relationships between PD symptoms and mental health outcomes. The resilience construct was originally developed within the child literature, and it is often used in conceptualizing how people have adaptive or positive outcomes when facing adversity. Current resilience measures may not adequately assess the construct within an older population, however, given the unique emotion regulation and coping skills seen in late …

The Relation Between Peer Victimization And Changes In Trauma Symptoms In Adolescents, Anh-Thuy H. Le

Theses and Dissertations

Peer victimization has been shown to negatively impact youth functioning and may be especially damaging during adolescence, given the increased importance of peers. However, there is a dearth of longitudinal research examining trauma symptomatology as an outcome of peer victimization with low-income, ethnic minority adolescents. The present study investigated this relation in a predominantly African American sample of 684 students assessed at five time points between the fall of their sixth grade and seventh grade school years. Growth mixture models grouped participants with similar victimization trajectories, and latent growth models related growth trajectories of physical and relational victimization to changes …

Visualization, Viewer And Emotion: An Empirical Study Of Cognition And Affective Responses To Infographics Used For Crisis Communication, Sean M. Stewart

Theses and Dissertations

A 3 (crisis response strategy) x 3 (medium) factorial design experiment was conducted to determine if information graphics conveyed through online news sources may be more beneficial for organizational reputations during some crisis situations than the use of news videos and text-based news stories. Variables examined include cognitive and affective appraisal, third-person effect, behavioral response and crisis response strategy.

Recent research in organizational crisis communications has pointed to the fact that more information is needed regarding how individuals react cognitively and affectively to crisis communications. Current crisis communications literature is also sparse concerning the behavioral aspects of crisis message reception …

Evaluation Of Psychological Services For Anxiety And Depression Provided In A University-Based Primary Care Clinic, Elizabeth J. Sadock

Theses and Dissertations

Primary care clinics are increasingly integrating psychological services into their service programs, however few studies have used a comparison group to demonstrate the effectiveness of these services. This study evaluated the psychological services provided at the Ambulatory Care Clinic (ACC) at the Virginia Commonwealth University Health System (VCUHS) by comparing changes in 147 patients’ PHQ-9 depression scores and GAD-7 anxiety scores over time to the scores of 139 patients at the Hayes E. Willis Health Center, a comparison clinic with demographically similar patients but no integrated psychological services. Assessment data were collected from participants in the ACC at VCUHS during …

Parent-Adolescent Communication About Sexual Topics, Cultural Factors, And Latino Adolescents’ Sexual Behavior And Condom Attitudes, Efren A. Velazquez

Theses and Dissertations

This study examined whether cultural values and gender moderate the association between mother-adolescent communication about sex and adolescents’ sexual behavior/intention to engage in sex and condom use attitudes. One hundred and fifty Latino adolescents completed an anonymous survey that measured sexual health outcomes, mother-child communication, and cultural factors. In bivariate analyses, adolescents with a higher sense of familismo had a more positive attitude towards using condoms and more acculturated Latino adolescents were less likely to speak to their mothers about pre-coital or coital sexual topics. Females spoke more about sex with their mother, compared to males. Traditional gender roles moderated …

Neighborhood Disorganization And Police Decision-Making In The New York City Police Department, Allison Carter

Theses and Dissertations

This dissertation examines the applicability of criminological theory to police decision-making during police-initiated encounters with suspects. Specifically, how indicators of social disorganization can be used to predict officers' use of coercive action (i.e., frisk, search, use of force, and arrest) during the street stop of suspects. I also investigate whether neighborhood disadvantage, as a moderator, impacts suspects' likelihood of receiving greater levels of coercive action when stopped for reasons listed in the New York City Police Departments' Unified Form 250 (UF-250) reports.

Three theoretical arguments connecting an officer's decision-making in a socially disorganized area are outlined. First, an area with …

Development Of A Collaborative Goal Setting Measure For Patients With Diabetes, Heather Morris

Theses and Dissertations

Introduction: The potential benefits of collaborative goal setting in the clinical setting have been shown. However, we have a limited understanding about what needs to have transpired between a patient and his or her clinician for them to report that they engaged in collaborative goal setting. Therefore, our ability to monitor and foster collaborative goal setting remains limited. Methods: My three-manuscript dissertation used a mixed-methods approach utilizing both qualitative and quantitative research methods. The aims of my study were to: (1) develop a conceptual model of collaborative goal setting as perceived by patients; (2) generate a list of survey items …

Characteristics Of Effective Communication About Mental Health In An African American Urban Community: A Qualitative Analysis, Jeannette Porter

Theses and Dissertations

Research has shown African Americans experience mental health issues at the same rate as the general population but seek treatment at only one-third that rate. Eleven African American low-income urban community leaders with basic training in mental health issues were interviewed about their perceptions of African American patterns of communication on mental health issues. Findings included a general consensus that the topic is generally not discussed, although passing references to a party’s perceived mental illness may be made using humor. When such discussion does take place, it happens only in a “safe space” with a trusted dialogue partner. Non-verbal cues …

The Impact Of A Primary Care Psychology Training Program On Medical Utilization In A Community Sample, Autumn Lanoye

Theses and Dissertations

Mental illness and psychological distress is associated with higher rates of medical service usage and treatment of these issues results in more appropriate medical utilization rates. Little research has been conducted in an integrated care clinic, wherein health psychologists or behavioral health specialists work together with physicians to provide patient care. The current study examines the effects of brief behavioral and mental health interventions on patient medical utilization in this setting with care delivered by medical residents and doctoral psychology trainees. Access to the health system’s electronic billing records allowed for objective measures of annual healthcare utilization in terms of …

Long-Term Outcomes Of Prolonged Exposure And Naltrexone For Patients With Comorbid Posttraumatic Stress Disorder And Alcohol Dependence, Shelley Avny

Theses and Dissertations

A growing body of research is examining effective treatment(s) for individuals with comorbid posttraumatic stress disorder (PTSD) and alcohol dependence (AD). However, treatments for this comorbid population have been inadequately studied in the longer term. This study represents a long-term follow-up assessment of a randomized controlled trial that compared combined therapy (prolonged exposure + naltrexone) with monotherapies (prolonged exposure or naltrexone) for patients with PTSD and AD (see Foa, Yusko, McLean et al., 2013). Attempts were made to contact 120 participants 5-10 years after the original trial to assess the maintenance of treatment gains. Nineteen individuals were located and agreed …

Food Landscapes: A Case Study Of A Cooking And Art- Focused Program For Teens Living In A Food Desert, Jessica R. Norris

Theses and Dissertations

This study constructs themes and propositions about the experiences of youth participants in the fall 2013 Food Landscapes program at the Neighborhood Resource Center in Richmond, Virginia. During the program, youth participated in cooking-based volunteerism with adults with disabilities and created short videos about their experiences. In this study, I analyzed pre- and post-program participant interviews, twice-weekly program observations, and facilitator reflections to understand how Food Landscapes affected youths’ conception of community engagement and communication strategies. This case study offers insight into how youth experience after-school programming of this design. Based on my findings, youth develop and rely upon a …

Seeing The Sausage Made: How Compromise Works In Large Groups And Representative Bodies, James E. Crawford Jr.

Theses and Dissertations

Inspired by the lack of Congressional compromise during the 2013 federal shutdown, I explore how compromise works in large groups and representative bodies. An on-line survey, personal interviews, and a discourse analysis of the Congressional Record yield a diverse collection of data, including personal and public stories of compromise. I examine the stories and other data through an eclectic mix of contemporary scholarship, borrowing literary theory from the Russian critic Mikhail Bakhtin, socio-linguistic concepts from American linguist James Paul Gee, and moral philosophy from Israeli thinker Avishai Margalit. I also incorporate the work of political scientists Amy Gutmann and Dennis …

The Influence Of Dementia Caregiver Mental Health On Quality Of Care In Argentina, Alejandra Morlett Paredes

Theses and Dissertations

This study examined the connections between cognitive functioning in individuals with dementia and caregiver burden, burden and mental health, mental health and quality of care. One hundred two dementia caregivers from San Lucas, Argentina completed questionnaires assessing these constructs. Caregiver burden, depression, anxiety, and satisfaction with life explained 18.8% of the variance in quality of care – respect and 14.7% of the variance in quality of care – provide. An SEM with generally adequate fit indices uncovered that cognitive functioning in individuals with dementia was inversely associated with caregiver burden, caregiver burden was inversely associated with mental health, and mental …

Disparities In Adverse Childhood Experiences And Sexual Health In The Us: Results From A Nationally Representative Sample, Monique J. Brown

Theses and Dissertations

Background: Adverse childhood experiences (ACEs) are a major public health problem in the US, and have been linked to risky sexual behavior and psychopathology. However, studies examining the link between the wide range of ACEs and sexual health outcomes and behaviors, and the associated mediational role of psychopathology are lacking.

Objectives: The main objectives of this dissertation project were: 1) To determine the association between ACEs and sexual health outcomes and behaviors (early sexual debut, intimate partner violence (IPV) perpetration, and HIV/STIs); 2) To examine the disparities among selected populations; and 3) To assess the mediational role of psychopathology in …

Stress Management For Cancer Survivors Using A Technologically Adapted Psychosocial Intervention: A Randomized Trial Determining The Effect Of Expressive Writing On Psychoneuroimmunology Based Outcomes, Utkarsh B. Subnis

Theses and Dissertations

Patients with cancer transitioning from completing their final cancer treatments to survivorship are particularly at risk for experiencing psychosocial stress, and the Institute of Medicine (IOM) has referred to these cancer patients as “lost in transition.” In this study, patients with cancer in their transition phase after completing their final radiation treatment were defined as cancer survivors (CS). CS must deal with chronic stressors such as the fear of cancer recurrence as well as the resumption of their roles in their family and work lives. Chronic stress impacts the nervous system and increases secretion of stress hormones (e.g. cortisol) from …

Characterization Of The Discriminative Stimulus Properties Of The Atypical Antipsychotic Amisulpride In C57bl/6 Mice, Timothy J. Donahue

Theses and Dissertations

Amisulpride, a benzamide derivative, is an atypical antipsychotic drug used to treat both schizophrenia and depression. Amisulpride is a selective antagonist at dopamine D₂ and D₃ receptors and at serotonin 5-HT_2B and 5-HT₇ receptors and displays an atypical clinical profile with reduced extrapyramidal motor effects. The drug has a chiral center and is a mixture of two optical isomers: (S)-amisulpride and (R)-amisulpride. The present study used a two-lever drug discrimination assay to allow a direct comparison between amisulpride and its two isomers. Additionally, substitution testing was conducted with the typical antipsychotics, atypical antipsychotics, antidepressants, …

Perceptions Of And Implicit Attitudes Toward Women: The Influence Of Parental Status, Race, And Label Choice, Annalucia Bays

Theses and Dissertations

Previous research suggests that childfree and childless women are perceived more negatively than mothers. This study investigated attitudes based on parental status, race, and descriptive label. Undergraduate students (N = 386) were randomized to consider targets described as childless, childfree, or mothers/parents. Participants completed a personality characteristic rating scale, the competence and warmth scales of the Stereotype Content Model, an evaluation thermometer, a measure of pronatalism, and a Single Category Implicit Association Test. Childless and childfree women of all races were perceived more negatively than mothers, and women in all parental status groups were ambivalently stereotyped. Implicit attitudes favored …

Implementing Social Equity In The Public Sector: How Community Colleges Achieve The Dream, Kasey J. Martin

Theses and Dissertations

Equity is an American ideal, one that is considered the cornerstone to good governance (Gooden, 2011). Achieving equity requires the eradication of racial disparities in opportunities and outcomes, particularly in education. Creating equitable educational experiences at community colleges is the focus of this research.

The purpose of study is to examine the issue of social equity within community colleges in an effort to understand: (1) their efforts to promote student success through equity; (2) their commitment to social equity; and (3) the institutional change that is necessary to create an institutional culture that values social equity and is accountable for …

Factors That Predict Incident Reporting Behavior In Certified Registered Nurse Anesthetists, Nicole K. Damico

Theses and Dissertations

Improving patient safety through reduction of medical errors is a national priority. One of the strategies widely utilized to address this issue is the use of incident reporting systems. The purpose of this study was to describe factors that predict the likelihood that Certified Registered Nurse Anesthetists (CRNAs) will use incident reporting systems, guided by the theory of planned behavior (Ajzen, 1991). A non-experimental, correlational research design was utilized to achieve the study aims. Following IRB approval, a cross-sectional survey was administered electronically to a random sample of practicing CRNAs. Correlational analyses and a standard logistic regression were utilized to …
