Drag Incorporated: The Homonormative Brand Culture Of Rupaul's Drag Race, Nathan T. Workman

Institute for the Humanities Theses

This thesis argues RuPaul’s Drag Race (RPDR, 2009–) positions itself as a homonormative pathway to LGBTQ+ social inclusion through privileging neoliberal selfbranding and commodity activist practices that reify privileged raced, classed, and sexuality identity markers. Utilizing interdisciplinary and intersectional cultural studies methods to conduct a textual analysis, I examine how RPDR produces homonormative LGBTQ+ identities through the commodification and standardization of drag cultures. In conversation with existing RPDR scholars, I critically survey RPDR’s gender biases and prosocial messaging as an example of brand culture’s reification of hegemony and homonormativity within LGBTQ+ communities. This research considers the …

A Meta-Analysis Of Group Treatment Outcomes For Veterans With Substance Use Disorders, Robert “Tony” Dice

Group therapy is commonly used in the treatment of substance use disorders (SUD). Many studies exist related to the efficacy of group interventions for veterans with SUDs. A meta-analysis and systematic review of the literature addressing the use of group therapy, specifically psychoeducational groups, cognitive behavioral therapy (CBT) groups and support groups, in the treatment of SUDs with veterans was conducted. The following questions guided the research: What are viable treatment outcomes for psychoeducational, CBT, and support groups of veterans with SUDs? and What are the measures that capture outcomes related to psychoeducational, CBT, and support groups of veterans with …

A Systemic Review And Meta-Analysis Of Psychoeducational Groups For The Treatment Of Psychopathology Resulting From Child Sexual Abuse, Alexis Lynnette Wilkerson

Counseling & Human Services Theses & Dissertations

It is estimated that 16% of men and 26% of women have experienced child sexual abuse (CSA), and studies have shown a strong association with long-term psychosocial consequences. The use of psychoeducational groups with survivors of CSA has been found to produce favorable outcomes; however, no meta-analyses have been conducted on studies assessing the use of psychoeducational groups to treat victims of CSA. The purpose of this systematic review and random-effect meta-analysis was to examine the efficacy of psychoeducational groups for the treatment of psychopathology subsequent to child sexual abuse (CSA) by addressing the following research questions (1) Are psychoeducational …

In The Margins: Reconsidering The Range And Contribution Of Diazotrophs In Nearshore Environments, Corday R. Selden

OES Theses and Dissertations

Dinitrogen (N₂) fixation enables primary production and, consequently, carbon dioxide drawdown in nitrogen (N) limited marine systems, exerting a powerful influence over the coupled carbon and N cycles. Our understanding of the environmental factors regulating its distribution and magnitude are largely based on the range and sensitivity of one genus, Trichodesmium. However, recent work suggests that the niche preferences of distinct diazotrophic (N₂ fixing) clades differ due to their metabolic and ecological diversity, hampering efforts to close the N budget and model N₂ fixation accurately. Here, I explore the range of N₂ fixation …

An Examination Of The Relationship Among Social Services Support, Race, Ethnicity And Recidivism In Justice Involved Mothers, Ne’Shaun Janay Borden

Counseling & Human Services Theses & Dissertations

Historically, women have been ignored and minimized in criminology research and theory, leading to gaps in the literature on justice involved women. In recent years, there has been more focus on women as their rates of involvement in the justice system have increased. Previous studies have found that pathways to justice involvement are different for women and men, with women experiencing higher rates of victimization, sexual abuse and mental health concerns. Further, justice involved women are unique in that over 80% are mothers or primary caregivers for minors. General Strain Theory is used to assert that receiving support should reduce …

Not Too Hot, Not Too Cold, But Moderately Variable: The Influence Of Environmental Variability On Coral Thermal Tolerance, Courtney Nicole Klepac

Biological Sciences Theses & Dissertations

Anthropogenic climate change is causing an increase in the frequency and severity of marine heat waves, resulting in declining health of coral reef ecosystems worldwide. Coral bleaching events – the breakdown in symbiosis between the coral host and their intracellular photosynthetic algae – are increasingly common in recent years and contribute to widespread losses in coral cover. However, bleaching and heat stress responses vary across spatial scales both within and among coral species. Coral populations native to highly variable environments can have greater bleaching resistance than corals from more stable habitats and corals transplanted into these variable reef sites can …

Drivers Of Rickettsial Pathogen Transmission And Spillover In Local Tick Populations In Southeastern Virginia, Alexandra Cumbie

Biomedical Sciences Theses & Dissertations

Cases of spotted fever group rickettsiosis are becoming more prevalent in the United States. In Virginia, there are three human-biting ticks which are largely responsible for the spread of rickettsial pathogens and the increase in disease cases. These species include Dermacentor variabilis, Amblyomma americanum, and Amblyomma maculatum; all of which are vectors of rickettsial agents to vertebrate hosts. These species are sympatric as adults and have the potential to share large and small mammal hosts. Their interactions on and off host and their associated rickettsiae were the focus of this dissertation work. Amblyomma americanum is the vector …

Synthesis And Characterization Of Carbohydrate Based Molecular Gelators And Macrocycles Through Cycloaddition Reactions, Dan Wang

Chemistry & Biochemistry Theses & Dissertations

Carbohydrate based low molecular weight gelators (LMWGs) are biocompatible and have many potential applications. They have been used for drug delivery, environmental clean-up, and for reaction catalysis. In recent years, copper catalyzed azide alkyne cycloaddition reactions (CuAACs) also termed “Click reactions” have shown great applications in the synthesis of various glycoconjugates and carbohydrate derivatives.

In this research, three diverse classes of glycoconjugates (I, II, III) have been designed and synthesized. The first class of compounds (I) in Chapter 2 are D-glucosamine based amide and triazole derivatives with different spacers between the amide and triazole (n=2-5) function groups. These compounds were …

Constraining Respired Carbon Storage In The Eastern Tropical Pacific Over The Last 25 Thousand Years Using Benthic Foraminiferal Boron/Calcium Ratios, Brian James Close

OES Theses and Dissertations

The storage of inorganic carbon in the deep Pacific Ocean is thought to play an important role in regulating both glacial-interglacial and millennial-scale atmospheric CO₂ concentrations (Broecker and Barker 2007; Sigman et al., 2010). A recent study by Loveley et al. (2017) showed that sedimentary authigenic uranium (aU) concentrations, a proxy for suboxic bottom-water conditions, increased significantly in the Eastern Equatorial Pacific (EEP) during the Last Glacial Maximum (LGM, 18 kyr – 23 kyr). If this is correct, the low-oxygen, CO_2-rich waters would also have a lower pH and a lower carbonate ion concentration ([CO₃^{2- …}

Sodium-Calcium Ratios In The Planktic Foraminifera Trilobatus Sacculifer As A Proxy For Sea Surface Salinity, Colton Steele Watkins

OES Theses and Dissertations

Recent culture and field studies have found a significant positive correlation between seawater salinity and the incorporation of sodium into foraminiferal calcite, suggesting a potential new proxy for reconstructing past changes in sea surface salinity (SSS) (Mezger et al., 2016 and Bertlich et al., 2018). In order to test the applicability of this new proxy in an open-ocean setting, Na/Ca ratios in the planktic foraminifera Trilobatus sacculifer (T. sacculifer Na/Ca) were measured from a suite of sediment core tops spanning a natural salinity gradient from the North Atlantic subtropical gyre to the South Atlantic subtropical gyre. Initial results from …

Defying The Odds: The Resilience Of African American Youth In The Face Of Differential Treatment In The Classroom, Frank R. Wood Jr.

Sociology & Criminal Justice Theses & Dissertations

In the education system, African American youth are confronted by deficit-based narratives of intellectual inferiority and defiance that inform teaching pedagogies, curricula, and classroom management strategies, such as school discipline practices. In light of available research documenting the deleterious effects of low expectations and treatment by teachers on the academic outcomes of African American youth, this body of knowledge also underscores the importance of racial socialization and positive perceptions of school bonding in safeguarding the academic achievement and success of African American youth. However, the lack of criminological inquiry into the complex associations between perceptions of differential treatment by teachers, …

Exploring The Niche Of Rickettsia Montanensis (Rickettsiales: Rickettsiaceae) Infection Of The American Dog Tick (Acari: Ixodidae), Using Multiple Species Distribution Model Approaches, Catherine A. Lippi, Holly Gaff, Alexis L. White, Heidi K. St. John, Allen L. Richards, Sadie J. Ryan

Biological Sciences Faculty Publications

The American dog tick, Dermacentor variabilis (Say) (Acari: Ixodidae), is a vector for several human diseasecausing pathogens such as tularemia, Rocky Mountain spotted fever, and the understudied spotted fever group rickettsiae (SFGR) infection caused by Rickettsia montanensis. It is important for public health planning and intervention to understand the distribution of this tick and pathogen encounter risk. Risk is often described in terms of vector distribution, but greatest risk may be concentrated where more vectors are positive for a given pathogen. When assessing species distributions, the choice of modeling framework and spatial layers used to make predictions are important. …

Fine-Scale Patterns Of Genetic Structure In The Host Plant Chamaecrista Fasciculata (Fabaceae) And Its Nodulating Rhizobia Symbionts, Mahboubeh Hosseinalizadeh Nobarinezhad, Lisa A. Wallace

Biological Sciences Faculty Publications

In natural plant populations, a fine-scale spatial genetic structure (SGS) can result from limited gene flow, selection pressures or spatial autocorrelation. However, limited gene flow is considered the predominant determinant in the establishment of SGS. With limited dispersal ability of bacterial cells in soil and host influence on their variety and abundance, spatial autocorrelation of bacterial communities associated with plants is expected. For this study, we collected genetic data from legume host plants, Chamaecrista fasciculata, their Bradyrhizobium symbionts and rhizosphere free-living bacteria at a small spatial scale to evaluate the extent to which symbiotic partners will have similar SGS …

Holy Stitches Batman, Or, Performative Villainy In Gothic/Am, A. Luxx Mishou

English Theses & Dissertations

Holy Stitches, Batman, or, Performative Villainy in Gothic/am is an interdisciplinary examination of gothic affect and deviant fashion in the narrative construction of villainy. It asks not just what a villain looks like, but what it means to look like a villain. A villain is a character who consciously and purposefully deviates from standards of normativity in order to pursue their own, often criminal, interests. The signifier of “villain” articulates a different purpose – an adversarial relationship with normativity that guides personal identification. Not exceptional to a gendered cultural system, they are informed by the societies in which they operate, …

An Analysis Of The Effect Of Digital Badging On Workplace Self-Directed E-Learners' Achievement, Persistence, And Self-Regulation, Emma Awuor Agola

STEMPS Theses & Dissertations

Despite the advantages and increase in popularity of self-directed e-learning, this mode of learning is still reported to suffer from low voluntary enrollment rates, high learner dropout rates, as well as low retention of learning. Although there is a paucity of motivation research with regard to self-directed e-learning, a considerable number of studies identify shortfalls in factors related to learner motivation as the most prevalent factor contributing to these pitfalls.

The current study investigated the effect of digital badges, an extrinsic reward, on learning effectiveness, persistence and self-regulation in a corporate self-directed e-learning environment. The study employed an experimental between-subjects …

Communication & Theatre Arts Theses

The following thesis is research into the Family Communication Patterns (FCP) (McLeod & Chaffee, 1972) of “alcoholics and drug addicts” (ADA) with long-term recovery stages III and IV. Improving relapse rates of ADA in early recovery stage I and stage II may require knowledge about the family communication environment and family type of those ADA with extended recovery time. This is an exploratory descriptive of FCP and family typology of 81 ADA identifying as Twelve-step fellowship (TSF) members recovering from the disease of addiction (Jellinek, 1947; 1960). Data was collected via online questionnaire with adapted scales; AWARE 3.0 relapse awareness …

Synthesis, Characterization, Spectroscopic, And Mesomorphic Studies Of New Schiff Base Ligands And Titanium, Cobalt, Nickel And Copper Metal Centers, Raj K. Gurung

Chemistry & Biochemistry Theses & Dissertations

Transition metal complexes with Schiff base ligands offer a wide application in the field of development of catalysis and material. The straightforward synthesis allowed the structural modification and helped to optimize in various application of such complexes. Titanium-containing complexes have been reported to be important for their catalytic and material applications through the coordination of a tetradentate Schiff base ligand, viz. N, N’-ethylene bis(salicylideneiminate) dianion (salen). Studies reporting the characterization of achiral titanium(IV) salen complexes are scarce due to their intricate nature. Such complexes would be comparatively less expensive and easier to prepare synthetically and thus could represent an …

A Multiple Case Study Investigating Principles Of Design And Implementation Of Operational Safety Plans For Crises At Colleges, Universities, And Affiliated Institutions, Antonio Passaro, Jr.

Educational Leadership & Workforce Development Theses & Dissertations

In the wake of the 2007 Virginia Tech tragedy, the Virginia state legislature mandated that all college-affiliated institutions create an operational safety plan for natural and manmade crises. Previous empirical research has mostly focused on documenting faculty and students’ perceptions of campus safety, preparations for manmade crises over natural disasters, and enhancing specific aspects of emergency responses for future incidents. Thus, design and implementation “best practices” for higher education operational safety plan protocols is an understudied, yet burgeoning area of inquiry. To address this literature gap, a comparative case study of five institutions was conducted using a novel document analysis …

Global Conservation Status Of Croaker And Drum (Family: Sciaenidae) And Role Of The Maw Trade, Claire E. Gorman

Biological Sciences Theses & Dissertations

Understanding threats and drivers of extinction risk is critical to conserving marine biodiversity. Although marine bony fishes are some of the most diverse and abundant vertebrates in the world, overexploitation is the major threat to these taxa. Species in the family Sciaenidae are important marine resources in many parts of the world, supporting small- and large-scale fisheries for consumption and the international maw (dried swimbladder) trade. Sciaenids exhibit a diverse array of life history characteristics, such as high fecundity, large body size, formation of spawning aggregations, and longevity. Some characteristics increase their susceptibility to anthropogenic stressors. Despite being ecologically and …

Ixodes Scapularis Src Kinase Is Required For Rickettsial Pathogen Survival In Ticks, Jeremy W. Turck

Biological Sciences Theses & Dissertations

Anaplasma phagocytophilum is an obligate intracellular bacterium that causes disease in humans and animals. It is the causative agent for human anaplasmosis. A. phagocytophilum uses certain strategies to infect both vertebrates and invertebrates. It uses Ixodes scapularis ticks as a vector for spreading infection to other mammal species. This bacterium has a specific path for infection through the salivary glands of its vector host. It also suppresses certain functions such as the inhibition of apoptosis and ROS production in order to increase its survival in ticks. Src kinase, a non-receptor protein-tyrosine kinase, is a major player in cell signaling. Src …

Assessment Of Factors Influencing Migratory Landbird Use Of Forested Stopover Sites Along The Delmarva Peninsula During Autumn Migration, J. Andrew Arnold

Biological Sciences Theses & Dissertations

Autumn migration is a time when billions of birds move from breeding grounds in North America to wintering grounds in Central and South America, with many individuals relying on stopover habitats en route for resting and refueling purposes. These stopover sites are critical to the survival of the hundreds of species of migratory landbirds that migrate annually, and thus identifying important stopover sites is a high priority for conserving such taxa. The Delmarva Peninsula; a coastal region of Delaware, Maryland, and Virginia along the mid-Atlantic flyway; consists of forested habitats with ample food and shelter that likely serves as quality …

Copper And Cobalt Metal Conjugation Enhances Flaviviral Replication, And Denv/Zikv Caused Thrombocytopenia Suppresses Integrin Signaling, Shovan Dutta

Biomedical Sciences Theses & Dissertations

Vector control is a global concern, and effective strategies have been on the way. Among the many different strategies, insect repellents to protect us from blood-feeding arthropods are very common. Food processing or preservatives in food expose us to several chemicals associated with insect repellents, insecticides, and pesticides. Using metallic conjugation with plant extracts or essential oils has become a widespread strategy to increase their efficacy. But it is worth it to be aware that some of those metallic compounds like Cobalt or Copper upon conjugation with thiosemicarbazone ligands derived from Citral and 2-acetylethiazole at the center coordination enhance both …

“How Could You Even Ask That?”: Moral Considerability, Uncertainty And Vulnerability In Social Robotics, Alexis Elder

The Journal of Sociotechnical Critique

When it comes to social robotics (robots that engage human social responses via “eyes” and other facial features, voice-based natural-language interactions, and even evocative movements), ethicists, particularly in European and North American traditions, are divided over whether and why they might be morally considerable. Some argue that moral considerability is based on internal psychological states like consciousness and sentience, and debate about thresholds of such features sufficient for ethical consideration, a move sometimes criticized for being overly dualistic in its framing of mind versus body. Others, meanwhile, focus on the effects of these robots on human beings, arguing that psychological …

Engineering Management & Systems Engineering Faculty Publications

This paper may be one of the first attempts dealing with the problem of creating, providing and maintaining antifragility of systems of interdependent urban critical infrastructures (CI) in the wake of black-swan type technological, ecological, economic or social catastrophes occurring in a municipality. A synonym is offered to describe antifragility from a positive psychology perspective, formulating the problem as the supraresilience problem. A brief description is given of the developed innovative approach for creating a supraresilient city/region using black-swan catastrophe and the antifragility concepts. Resilience metrics are formulated as well as methods of assessing damage, interdependence of infrastructures and convergent …

Modulation Of Ros In Nanosecond-Pulsed Plasma-Activated Media For Dosage-Dependent Cancer Cell Inactivation In Vitro, Chunqi Jiang, Esin Bengisu Sozer, Shutong Song, Nicola Lai, P. Thomas Vernier, Sigi Guo

Bioelectrics Publications

Dosage control of reactive oxygen and nitrogen species (RONS) is critical to low-temperature plasma applications in cancer therapy. Production of RONS by atmospheric pressure, nonequilibrium plasmas in contact with liquid may be modulated via plasma conditions including plasma treatment time and pulse voltage and repetition frequency. In this study, a terephthalic acid-based probe was used to measure hydroxyl radicals [OH_aq] in water exposed to plasma and to demonstrate that the OH_ag concentration increases linearly with treatment time. Fluorometric measurements of hydrogen peroxide concentration in plasma-activated water show a linear relationship between the H₂O₂ production …

Potential Virus-Mediated Nitrogen Cycling In Oxygen-Depleted Oceanic Waters, M. Consuelo Gazitúa, Dean R. Vik, Simon Roux, Ann C. Gregory, Benjamin Bolduc, Brittany Widner, Margaret R. Mulholland, Steven J. Hallam, Osvaldo Ulloa, Matthew B. Sullivan

OES Faculty Publications

Viruses play an important role in the ecology and biogeochemistry of marine ecosystems. Beyond mortality and gene transfer, viruses can reprogram microbial metabolism during infection by expressing auxiliary metabolic genes (AMGs) involved in photosynthesis, central carbon metabolism, and nutrient cycling. While previous studies have focused on AMG diversity in the sunlit and dark ocean, less is known about the role of viruses in shaping metabolic networks along redox gradients associated with marine oxygen minimum zones (OMZs). Here, we analyzed relatively quantitative viral metagenomic datasets that profiled the oxygen gradient across Eastern Tropical South Pacific (ETSP) OMZ waters, assessing whether OMZ …

Swimming Point Benthic Community Condition Elizabeth River (2019), Daniel M. Dauer

Elizabeth River Reports

Executive Summary

The subtidal macrobenthic communities off Swimming Point in the Elizabeth River were quantitatively sampled in summer 2019. The primary objective of this study was to characterize the ecological condition of the benthos compared to benthic data collected in summer 2010 (Dauer 2011).

The estimated the level of degraded benthic bottom of the Swimming Point stratum (BIBI < 3.0) in 2019 was 64% ± 18.8% a decrease from the 2010 value of 84% ± 14.0%. The level of severely degraded bottom (BIBI ≤ 2.0) in 2019 was 28% ± 17.6% compared to the 2010 value of 52% ± 19.6%. The ecological condition of benthic communities at Swimming Point in 2019 were comparable to the values for the Mainstem segment of the Elizabeth River in 2019 which had an estimated degraded benthic bottom of 52% ± 19.6% and a value of 36% ± 18.8 of severely degraded bottom.

The BIBI and its metrics showed a mixture of improvements and degradations in benthic community condition. Compared to the previous benthic community condition reported in Dauer (2011) the 2019 Swimming Point benthos: (1) the average BIBI value improved significantly from 2.2 ± …
