A Novel Parking Management In Smart City Vehicular Datacenters, Syed Rizvi, Susan Zehra, Steven Olariu

College of Sciences Posters

Researchers have shown that most vehicles spend the majority of their time parked in parking garages, lots, or driveways. During this time, their computing resources are unused and untapped. This has led to substantial interest in Vehicular Cloud, an area of research in which each vehicle acts as a computation node. The main difference between traditional cloud computing and vehicular cloud computing is the availability of nodes. In traditional clouds, nodes are available 24/7, while in vehicular clouds, nodes (vehicles) are only available while parked in parking lots. This creates a dynamic environment as vehicles enter and exit parking garages …

School of Public Service Faculty Publications

This study examines households' prospective evacuation behavior during a hurricane-pandemic compound threat. Data from a 2020 survey of coastal Virginia households help answer two questions: (1) What factors associated with the threat and impacts of the COVID-19 pandemic and hurricanes influence prospective evacuation behavior of households during a compound hurricane-pandemic event? (2) What are the equity implications for emergency management policies and practices to support evacuation and sheltering during a compound hurricane-pandemic event? Households in the sample were split between those who stated they would evacuate away from the at-risk region and who would stay. Greater household vulnerability to hurricanes …

Biodiversity Of Philippine Marine Fishes: A Dna Barcode Reference Library Based On Voucher Specimens, Katherine E. Bemis, Matthew G. Girard, Mudjekeewis D. Santos, Kent E. Carpenter, Jonathan R. Deeds, Diane E. Pitassy, Nicko Amor L. Flores, Elizabeth S. Hunter, Amy C. Driskell, Kenneth S. Macdonald Iii, Lee A. Weigt, Jeffrey T. Williams

Biological Sciences Faculty Publications

Accurate identification of fishes is essential for understanding their biology and to ensure food safety for consumers. DNA barcoding is an important tool because it can verify identifications of both whole and processed fishes that have had key morphological characters removed (e.g., filets, fish meal); however, DNA reference libraries are incomplete, and public repositories for sequence data contain incorrectly identified sequences. During a nine-year sampling program in the Philippines, a global biodiversity hotspot for marine fishes, we developed a verified reference library of cytochrome c oxidase subunit I (COI) sequences for 2,525 specimens representing 984 species. Specimens were primarily purchased …

Are Ride-Hailing Services Safer Than Taxis? A Multivariate Spatial Approach With Accomodation Of Exposure Uncertainty, Guocong Zhai, Kun Xie, Hong Yang, Di Yang

Civil & Environmental Engineering Faculty Publications

Despite many research efforts on ride-hailing services and taxis, limited studies have compared the safety performance of the two modes. A major challenge is the need for reliable mode-specific exposure data to model their safety outcomes. Moreover, crash frequencies of the two modes by injury severities tend to be spatially and inherently correlated. To fully address these issues, this study proposes a novel multivariate conditional autoregressive model considering measurement errors in mode-specific exposures (MVCARME). More specially, a classical measurement error structure is used to accommodate the uncertainty of mode-specific exposures estimated, and a multivariate spatial specification is adopted to capture …

Civil & Environmental Engineering Faculty Publications

Safety Service Patrols (SSPs) provide motorists with assistance free of charge on most freeways and some key primary roads in Virginia. This research project is focused on developing a tool to help the Virginia Department of Transportation (VDOT) optimize SSP routes and schedules (hereafter called SSP-OPT). The computational tool, SSP-OPT, takes readily available data (e.g., corridor and segment lengths, turnaround points, average annual daily traffic) and outputs potential SSP configurations that meet the desired criteria and produce the best possible performance metrics for a given corridor. At a high level, the main components of the developed tool include capabilities to: …

Incorporating Public Health Into Transportation Decision Making, Bruce Appleyard, Tim Garrett

Mineta Transportation Institute

Investments in transportation have the potential to significantly affect public health outcomes. Decisions to build highways, transit, or bikeways, for example, influence how residents and visitors move around a metropolitan area. Personal travel habits and proximity to transportation infrastructure play a role in how likely people are to be physically active or be exposed to dangerous traffic and toxic pollution. For this study, the research team reviewed the literature that links transportation infrastructure, the surrounding built environment context, and public health outcomes such as chronic heart and lung diseases, obesity, and death. The team then researched publicly available data that …

Police Response To Same-Sex Ipv A Qualitative Approach, Lena Fae Mutchler

Graduate Research Theses & Dissertations

The present thesis examines the views that police have towards cases of same-sex IPV(intimate partner violence) in a qualitative sense. An issue highlighted by poor relations and uneven rates of arrest; this study sought to look beyond the usual quantitative approach to the issue. This was analyzed through use of semi-structured interviews with both law enforcement and social service workers in domestic violence organizations. 13 interviews were conducted, 6 with law enforcement, and 7 with social service workers, asking the participants about their views and interactions with same-sex cases, police, and the LGBTQ community as a whole. The results implied …

Undocumented Students’ Voice, Mtss, And School Counselors’ Mental Health Advocacy: A Transformative Mixed Methods Study, Oliver Camacho

Graduate Research Theses & Dissertations

Many young undocumented students are experiencing mental health issues in K-12 schools. Researchers have found a myriad of psychological stressors that add to the complexity of being an undocumented student in the United States. Educators have noted an increased concern in undocumented students expressing concerns of fears at school, acculturation stress, migratory stress, heightened reports of depression, increased anxiety, and a proclivity towards emotional and behavioral problems. There is limited research that reviews mental health supports in schools for undocumented students that includes the voices of school counselors and undocumented students in a transformative paradigm. This study seeks to inform …

Three Essays On The Effects Of Parental Income And Labor Supply On Child Health And Labor Market Outcomes., Kassahun Mamo Geleta

Graduate Research Theses & Dissertations

This dissertation constitutes three separate essays on labor and health economics using the Panel Study of Income Dynamics (PSID) dataset. The first essay examines the long-run effect of childhood poverty on labor market outcomes using propensity score matching (PSM) and average causal mediation effect (ACME) methods. The results show that persistent childhood poverty significantly decreases average annual labor income and hours worked, whereas it increases the number of weeks unemployed per annum during adulthood. The study also shows that a significant portion of the total effect of childhood poverty on labor market outcomes passes indirectly through its negative effect on …

Cybervictimization And Depression In Adolescence: An Analysis Of Anxiety, Social Media Rumination, And Gender, Logan Riffle

Graduate Research Theses & Dissertations

Bullying is not a new phenomenon, however, given the frequent technology use by youth, bullying has taken on a new platform, the internet (i.e., cyberbullying). Those who are victimized online are at risk for various unfortunate outcomes, such as depression. The World Health Organization (WHO) identifies depression as the "single largest contributor to global disability," and the impacts of depression are vast, affecting the daily lives of many. Among a sample of middle school students (N = 126), the current study initially sought to investigate whether symptoms of social anxiety and social media rumination (SMR) serially mediated the association between …

Serious Conduct Problems And Callous Unemotional Traits In Offending Adolescents: Unique And Shared Contributions Of Parenting And Community Risk, Elizabeth R. Corning

Graduate Research Theses & Dissertations

A growing body of research has suggested that parenting behaviors influence the development of youth conduct problems (CP) and callous-unemotional traits (CU). However, few studies have examined how parenting impacts CP and CU growth over time, and whether these associations differ based on the presence of additional community-level risk factors. This study used data from the Pathways to Desistance project (N = 1,354) to investigate how distinct parenting behaviors (i.e., positive parenting, harsh parenting, and parental knowledge) impact the initial level and growth in CP and CU across four years among adolescents involved in the juvenile justice system. Interaction effects …

Efficacy Of A Brief Mindfulness Intervention For Not-Just-Right Experiences, Samuel Richard Cares

Graduate Research Theses & Dissertations

The obsessions and compulsions that define the diagnosis of Obsessive-Compulsive Disorder (OCD) traditionally have been characterized by harm avoidance. However, harm avoidance is neither specific to OCD nor does it comprehensively explain all symptoms with which individuals with OCD present. Emerging research has focused on incompleteness—and its manifestation through the phenomenon of not just right experiences (NJREs)—as a potential motivating factor for OCD symptoms. Whereas Exposure and Response Prevention (ERP) is conceptually relevant to—and empirically supported for treating—symptoms characterized by harm avoidance, there is an unclear connection between ERP and symptoms characterized by incompleteness. Research has begun to explore ways …

Impact Of Text Complexity Effects Across Student Reading Skills, Esther H. Yi

Graduate Research Theses & Dissertations

A reader’s ability to go beyond their surface-level understanding of words and to build a deeper representation of the text in their mind (i.e., reading comprehension) is predicated on a range of reader- and text-level variables that indicate how well a certain reader can read a certain text. The following study evaluates the extent to which the interaction between the reader characteristics of fifty first graders (e.g., decoding and oral reading fluency skill and demographic characteristics) and the textual characteristics of commonly administered, first grade oral reading fluency passages (e.g., text complexity) may impact the participants’ reading comprehension of the …

Assessing Engagement In Bully Participant Behaviors For Children And Adolescents With Autism Spectrum Disorder, Dashae Rodriguez-Harris

Graduate Research Theses & Dissertations

Children and adolescents with autism spectrum disorder (ASD) are at an increased risk of involvement in bully participant behaviors, particularly as victims. Engagement in bully participant behaviors has been associated with a variety of poor academic, behavioral, and emotional outcomes for individuals with ASD. The current investigated the rates of involvement in bully participant behaviors engagement for youth with ASD. Additionally, the associations between social emotional competence and reported rates of bully participant behaviors were examined to determine if ratings of SEL competence by adults could be utilized to assess who is at risk of involvement in bullying without directly …

Intergenerational Transmission Of Parenting: Does Emotion Regulation Buffer The Effect Of Negative Early Care Experiences On The Cortisol Stress Response And Subsequent Caregiving?, Erin Rochelle Mckay

Graduate Research Theses & Dissertations

A phenomenon known as the intergenerational transmission of parenting, where children tend to parent their children in a manner similar to how their own parents provided care, has received notable attention within developmental research. While several mechanisms focusing on cognitive and psychological factors have been proposed, there is less research examining biological mechanisms within the intergenerational transmission of parenting framework, especially when considering caregiving behavior exhibited in the context of child distress. Further, few studies have examined parent attributes which may disrupt the intergenerational transmission of parenting. The current study seeks to examine the hypothalamic-pituitary-adrenal (HPA) axis stress response as …

Local Radio Journalists’ Usage And Perception Of Artificial Intelligence In The Production Of Local News, Imani Nia Springer-Norris

Graduate Research Theses & Dissertations

The study of human-machine communication seeks to explore journalists’ opinions and perceptions of artificial intelligence (AI) in the newsmaking process, but few studies explore the impact of artificial intelligence on local news, particularly local nonprofit radio journalism. In a case study of a midwestern NPR affiliate, nine local radio journalists were interviewed about how they use AI technology at their local station and their opinions about the role of artificial intelligence as a communicator. My results showed that local radio journalists were primarily using AI for transcription, but that the station was experimenting with other AI tools for the purpose …

Enhanced Maximum Likelihood Models For Underreported Variables: Extending To Multiple Claims Dimension, Shalaka Sudhanshu Sarpotdar

Graduate Research Theses & Dissertations

This thesis builds upon the foundations laid out in Xia et al. [2023], which explored the utilizationof Maximum Likelihood approach to model misrepresentation data in Generalized Linear Models (GLM) ratemaking models. We introduce the concept of “underreported variables”, a form of insurance misrepresentation where insured individuals provide inaccurate information about risk factors that influence insurance eligibility, premiums, and insured amounts. Unlike fraudulent misrepresentation, underreported variables arise from a lack of awareness regarding the insured’s mental and physical health conditions, rather than fraudulent intent. The study rigorously tests the proposed model using health insurance data and extends its applicability to other …

Why Does Un Peacekeeping Fail To Disarm And Demobilize Warring Parties In Intrastate Conflicts? A Cross-Case Comparative Analysis Of Cambodia And Angola, Socheata Meas

Graduate Research Theses & Dissertations

Second-generation peace operation is big in size and complex in operations and has positively impacted society and humankind and brought about peaceful endings in some conflicts. Nevertheless, studies in the area show that some peacekeeping has failed, and many limitations in each operation lead to UN peacekeeping failure. The failure of UN peacekeeping to disarm and demobilize warring parties’ armed forces has been researched explicitly by scholars. However, those scholarships have limitations in explaining why the UN fails to disarm and demobilize warring parties in intrastate conflict. This thesis paper will look at the UN's failure to disarm and demobilize …

Marginalized Community College Students' Perspectives Of Their First Time In Honors And Experiences With Tracking, Trina Sotirakopulos

Graduate Research Theses & Dissertations

Many of the variables that determine college admission are beyond a student’s control, including the academic track they were assigned as early as primary school—often referred to as “ability-grouping” or skills-homogeneous classes. Even in higher education, students feel the effects of unequal sorting and sifting from tracking. The purpose of this study was to learn from marginalized community college students who were in low and middle track courses in high school. The study located how socially marginalized students taking honors courses for the first time perceived their past experiences with tracking, current opportunities in community college honors, and ways tracking …

Young Adolescents’ And Parents’ Attitudes And Perspective Taking About Appropriate Mobile Phone Use, Stephanie Jean Cleary

Graduate Research Theses & Dissertations

This study explored whether young adolescents and their parents have similar attitudes about appropriate mobile phone use, and whether those attitudes vary depending upon adolescent or parent phone user, the mobile phone use context (i.e., family dinner table, party, or homework/ work), and their self-perspective or other’s perspective. Fifty-two adolescents in 6th, 7th, and 8th grade (age range 11 years to 14 years and 5 months; 26 males, 23 females, 3 non-binaries) and their parent or guardian participated. Adolescents identified as white/European American (82.7%), multiple races (5.8%), Asian (5.8%), black/African American (1.9%), and Hispanic/Latinx/Spanish (1.9%), or did not respond (1.9%). …

Nigerian Media: A Comparative Media Analysis, Temilade Inumidun Adeeko

Graduate Research Theses & Dissertations

The comparative media analysis of Nigeria using Hallin and Mancini's model provides an insightful examination of the country's media system. Hallin and Mancini's model analyzes four dimensions: the degree of state intervention, the degree of political parallelism, the level of journalistic professionalism, and the role of the state. They offer three models of media and politics: The Liberal model, the Democratic Corporatist, and the Polarized Pluralist. Nigeria’s media system is characterized by high state intervention and political parallelism, significant control over media content by the state, a close relationship between the media and political parties, and a low level of …

Herstory 101: Examining The Representation Gap Of Bipoc Women Educational Leaders, Kinasha Brown

Graduate Research Theses & Dissertations

Background/Purpose: The purpose of this study was to examine how lived experiences influenced perceptions of leadership self-efficacy amongst Black, Indigenous, or Person of Color (BIPOC) women educational leaders in order to minimize future representation gaps in educational leadership. Methods: Qualitative interviews were conducted with 14 BIPOC cis-gender female leaders who worked in a large school district in the southwestern region of the United States. Results: Examining the social constructs of race, gender, leadership makes clear how BIPOC women are socially constructed as inferior and how that played out in this educational leadership settings. The interconnectedness of both approaches contributes to …

Evaluating The Impact Of Examiner Variability On The Verbal Comprehension Index Of The Wisc-V, Brooke A. Butcher

Graduate Research Theses & Dissertations

The purpose of the current study was to: a) explore rater variability on the VCI, b) explore rater tendencies, and c) compare rater tendencies between graduate students and licensed and/or certified school psychologists. Considering the results of prior literature that has investigated scoring errors and inter-rater agreement on the WISC, it was hypothesized that examiners would be significantly different from one another (overall and between groups) in terms of their tendencies towards severity/leniency on the Vocabulary and Similarities subtests. Raters (N = 10) were comprised of two groups: a) graduate students in training to become school psychologists (n = 5) …

Christianity And Mental Health Counseling: Voices Of The Black-Negro American Experience, Kyle Preston Goodwin

Graduate Research Theses & Dissertations

The narration of the lived experiences of Black-Negro Christian Americans in relation to mental health counseling services is vital because opportunities for researchers and clinicians to hear their voices instead of a story written for them by the leading culture is created. Specifically, when it comes to Black-Negro spirituality and religion as part of Black-Negro culture, it is one of the most beautiful and intriguing experiences that exists. A critical theory paradigm is being used for how knowledge is created and disseminated for the purposes of social change. Narrative Qualitative research is used to capture the Black-Negro voice, along with …

Uruguayan Parents' Perceptions About Educational Segregation In Uruguayan Public Elementary Schools: A Case Study, Natalia Fernández

Graduate Research Theses & Dissertations

Educational segregation has been increasing across public elementary schools in Uruguay producing negative effects on students’ outcomes, performance, and opportunities. It also affects social cohesion. Previous studies detect the presence of educational segregation in Uruguay, identify the predominance of socioeconomic segregation in education in the country, and study the relationships between public and private institutions. A review of the extant literature demonstrates there is a gap in the exploration of the possible factors that contribute to the phenomenon. Moreover, there is a need to know the perceptions and experiences of Uruguayan families about the influence of these factors in their …

Evaluating The Impact Of Bitcoin On International Asset Allocation Using Mean-Variance, Conditional Value-At-Risk (Cvar), And Markov Regime Switching Approaches, Mohammadreza Mahmoudi

Graduate Research Theses & Dissertations

This paper aims to analyze the effect of Bitcoin on portfolio optimization using mean-variance, conditional value-at-risk (CVaR), and Markov regime switching approaches. I assessed each approach and developed the next based on the prior approach’s weaknesses until I ended with a high level of confidence in the final approach. Though the results of mean-variance and CVaR frameworks indicate that Bitcoin improves the diversification of a well-diversified international portfolio, they assume that assets’ returns are developed linearly and normally distributed. However, the Bitcoin return does not have both of these characteristics. Due to this, I developed a Markov regime switching approach …

A Single-Case Alternating Treatments Design Utilzing Quantitative Electroencephalography To Observe And Measure Mental State Trends During Individual Participant Non-Nature-Based Small Initiative Adventure Therapy Experiences, Patrick Lane Robert Mcmillion

Graduate Research Theses & Dissertations

This single-case alternating-treatments design research study observed and measured mental state trends during the counseling approach known as Adventure Therapy (AT) using quantitative electroencephalography (qEEG). Participants wore a qEEG headset while participating in a multi-stage AT experience. Two problems were addressed in this study. The first was the lack of research in AT utilizing other empirical measures beyond subjective report surveys and the outcomes of specific programs. The second was the lack of neuroscientific measurement of counseling approaches and interventions within the field of counseling in general. There is a need for empirical evidence supporting AT to address access barriers …

Social Media, Gender, And Cancel Culture In The Punk Scene, Elizabeth Alexandra Mitchell

Graduate Research Theses & Dissertations

This thesis intends to examine the technological, political, and social dynamics surrounding the cancelation of musicians within the punk scene, specifically, modern Bay Area punk band, SWMRS. The technological dynamics involve the internet, networked publics, and digital politics. The social dynamics are not separate from sociality facilitated by social media and the networks they create. The politics of this context involves gender and the struggle over women’s agency to fight against sexual abuse and the social injustice it perpetuates. Because this thesis is interested in these issues within the context of popular music, it draws on the work on music …

The Impact Of Credit On Domestic Investment: Case Of West African Economic And Monetary Union Countries, Sylvie Sanou

Graduate Research Theses & Dissertations

This thesis evaluates the impact of credit offered by the banking system on the investment rate of seven West African countries that are members of the West African Economic and Monetary Union (WAEMU) countries using data from the World Bank dataset from 1996-2012. Using a fixed effect model and random intercept model, I find that the credit offered by the banking system to private investors has a positive and statistically significant effect on the investment rate. In contrast, no significant effect was found for the credit offered by the banking system to the government. Further, I find a negative relationship …
