No Woman Is An Island, Adele Ball

Theses and Dissertations

We have gathered the following pages to archive our time here in Richmond, Virginia. We have been here for two years, growing slowly, moving when needed to new anchorholds to avoid detection or arrest. We scrutinize the urban environment like modern archeologists. We collect stories and speculate about new uses of old things. It is imperative to be resourceful here, and we do so out of necessity but also in the spirit of practice. These pages were made en route, each an exploration of the tools at hand when on the move. The method of creation is just as important …

"Fuck Off, Get Free, Love And Love's The Only Thing", David S. Moré

Theses and Dissertations

A child, angry at concrete and strip malls, enjoying coffee from too many styrofoam cups.

Loosely Bound, Alexander Martin

Theses and Dissertations

I take a poetic approach to graphic design practice. It is a subjectivist approach, which recognizes our human right to willful interpretation. Designers navigate form, culture, and history like poets through language. We are subjective, exploratory engines drawing formal inspiration from figural and analogical associations. Subjectivity in graphic design practice is complex, however. Subjectivity privileges the interaction between object and individual. When we designers interpret the literal world with the poet’s omni-directional sensitivity, we intentionally and intuitively create objects that accrete inexhaustible, extra-literal value for their audience.

Choreographic Space, Kelsey Sheaffer

Theses and Dissertations

This thesis, Choreographic Space, and accompanying exhibit is an arrangement of contemporary work being done in the cross-over between movement, drawing, sound and architecture. The thesis develops a lineage of choreographic thinking through a fissure in the classification of a dance as necessarily the body in motion. Through the link of the “choreographic object,” Choreographic Space asks how an interdisciplinary exploration of the principles of movement can reveal novel ways to think about the body in space.

The Curiosity Of Con, Petrified Breath, And An Accident Known As Blue., Steven Randall

Theses and Dissertations

My thesis installation emerged from an interest in visualizing breath. The resulting work came to exist at the intersection between art, biology, and performance.

The unicorn tapestries were used as a generative point of departure to explore the preservation and transformation of images through time, by time, and with time. Reproductions of the six tapestries were each etched into paper and then submerged into solutions of Phenol Red dye, Ferric Ferrocyanide (also known as Prussian Blue), and various forms of sodium chloride. Exhaled breath was used to encrust these images of the tapestries into physical objects which gradually crystallized and …

Design Thinking For The Development Of Formal Operations: A Team-Based Middle School Design Curriculum, Stephanie K. O'Dell

Theses and Dissertations

In this thesis, I propose a team-based design curriculum that aligns with the cognitive development of middle school age students. The ability to think abstractly develops at a specific time in development, according to widely accepted cognitive theory. The middle school years are the launching pad of abstract thinking. At this age, students are also primed for learning through social activity. The design process often includes abstract problem solving challenges, and working within a team structure. These ideas build a foundation for a research question—could a team-based design curriculum in middle school strengthen students’ natural cognitive development by providing opportunities …

A (Dis)Assemblage Of The Gallery-Growlery, Levester R. Williams

Theses and Dissertations

A (dis)Assemblage of the Gallery-Growlery exhibition and writing presents itself as a site of a morphological exploration of language, sound, and objects in tandem with the irreducibly venting black expression. Venting, the black expression never seeks wholeness within objects or language itself for it is a thing-in-itself. Its presence affords critical reception to a residue of delimiting forms. All growls eschew verbal objects for the manifestation of pure phonetics. A growl in a gallery is the growl. The growl resounds through the physicality of the objects and gallery. Also, it unwinds the object-among-objects as the phono-present stretches the discursive …

Monitor, Shana Hoehn

Theses and Dissertations

Descriptions of a scene interwoven with thoughts on how aesthetics sets behavioral expectations, observation as proof, views from a single perspective, casting of characters, spaces that evoke complicated histories, and my own history.

Hybrid Straintronics-Spintronics: Energy-Efficient Non-Volatile Devices For Boolean And Non-Boolean Computation, Ayan K. Biswas

Theses and Dissertations

Research in future generation computing is focused on reducing energy dissipation while maintaining the switching speed in a binary operation to continue the current trend of increasing transistor-density according to Moore’s law. Unlike charge-based CMOS technology, spin-based nanomagnetic technology, based on switching bistable magnetization of single domain shape-anisotropic nanomagnets, has the potential to achieve ultralow energy dissipation due to the fact that no charge motion is directly involved in switching. However, switching of magnetization has not been any less dissipative than switching transistors because most magnet switching schemes involve generating a current to produce a magnetic field, or spin transfer …

Systematic Postsynthetic Modification Of Nanoporous Organic Frameworks And Their Performance Evaluation For Selective Co2 Capture, Timur Islamoglu

Theses and Dissertations

Porous organic polymers (POPs) with high physicochemical stability have attracted significant attention from the scientific community as promising platforms for small gas separation adsorbents. Although POPs have amorphous morphology in general, with the help of organic chemistry toolbox, ultrahigh surface area materials can be synthesized. In particular, nitrogen-rich POPs have been studied intensively due to their enhanced framework-CO₂ interactions. Postsynthetic modification (PSM) of POPs has been instrumental for incorporating different functional groups into the pores of POPs which would increase the CO₂ capture properties. We have shown that functionalizing the surface of POPs with nitro and amine groups …

Are You Covered? Examining How Knowledge Of The Patient Protection And Affordable Care Act Influences Use Of Preventive Reproductive Health Services, Ashlee Sawyer

Theses and Dissertations

The Patient Protection and Affordable Care Act (PPACA) expanded access to insurance coverage and health care services for many citizens, and has increased access for women in particular by including preventive reproductive health services as essential health benefits. The current national rates of sexually transmitted infections (STIs), reproductive cancer diagnoses, and unintended pregnancy serve as major areas of concern for women’s health and public health. The present study examined how knowledge of the PPACA influences receipt of preventive reproductive health services among women. Results indicate that higher levels of knowledge of the PPACA are associated with a greater likelihood of …

Death Vegas Valley, Eric M. Diehl

Theses and Dissertations

My work explores hallucinatory landscapes of the US American West by using a combination of painting styles outside of the Western painting canon. I cross-reference painting and cinema, interweaving video, acrylic paint and the panorama to create a satirical homage to the history and present state of the USA. However, through an earnest devotion to the medium - both painting and cinema - I find my criticisms also yearn to hold onto a belief in a myth I know to be false.

This is an American History conversation about artifice and consumerism through advertising. I use Las Vegas and the …

Telomere Length In Women With Breast Cancer: A Longitudinal Study Of Their Relationship To Chemotherapy And Acquired Psychoneurological Symptoms, Areej Alhareeri

Theses and Dissertations

Breast Cancer (BC) is one of the most commonly diagnosed malignancies in females. The 5-year survival rate for women with early stage BC is about 90%. However, the quality of life (QOL) for many of these women may be adversely affected due to treatment/cancer–related side effects, including a constellation of symptoms (anxiety, depression, pain, fatigue, sleep disturbance and depression), that are collectively termed psychoneurological symptoms (PNS). To gain insight into the contributory role of telomere length (TL) in the development and persistence of PNS, we have longitudinally studied 72 women (ages 23-71) with early stage BC (I-IIIA) at 5 time …

This thesis details elements of my paintings in exchange with methods and ideas from artists and writers in order to position my aesthetic and conceptual sensibilities within a historical and contemporary framework.

Momentum Clinic For Teen And Young Adult Cancer Patients, Merian O'Neil

Theses and Dissertations

This study explores the needs of teen and young adult cancer patients undergoing long-term chemotherapy treatments and the design of an outpatient clinic that accommodates this population’s unique needs. Most teens endure long-term treatments in a pediatric facility targeted primarily for children, while others are treated in adult facilities. Teens have different privacy and social needs than children, and while they are not adults, they are involved in their own treatment decisions, unlike children. The target age group for this study is teens and young adults, ages thirteen to twenty-two. A common theme emerged from research and interviews conducted in …

Novel Small Airway Model Using Electrospun Decellularized Lung Extracellular Matrix, Bethany M. Young

Theses and Dissertations

Chronic respiratory diseases affects many people worldwide with little known about the mechanisms diving the pathology, making it difficult to find a cure. Improving the understanding of smooth muscle and extracellular matrix (ECM) interaction is key to developing a remedy to this leading cause of death. With currently no relevant or controllable in vivo or in vitro model to investigate diseased and normal interactions of small airway components, the development of a physiologically relevant in vitro model with comparable cell attachment, signaling, and organization is necessary to develop new treatments for airway disease. The goal of this study is to …

Direct L2 Support Vector Machine, Ljiljana Zigic

Theses and Dissertations

This dissertation introduces a novel model for solving the L2 support vector machine dubbed Direct L2 Support Vector Machine (DL2 SVM). DL2 SVM represents a new classification model that transforms the SVM's underlying quadratic programming problem into a system of linear equations with nonnegativity constraints. The devised system of linear equations has a symmetric positive definite matrix and a solution vector has to be nonnegative.

Furthermore, this dissertation introduces a novel algorithm dubbed Non-Negative Iterative Single Data Algorithm (NN ISDA) which solves the underlying DL2 SVM's constrained system of equations. This solver shows significant speedup compared to several other state-of-the-art …

Through discursive essays and poetic narrative, Antithetical Commentaries on X, Y and the Disruption of Being explores the tenuous relationship between modes of measurement and the struggle for human relevance in the post-contemporary digital age. In the introductory essay, “Not the Feather, but the Bird”, I give an overview of the inherent problems of object-oriented ontology, and how it relates to aesthetics and social issues of our times. In the Developmental Overview, I detail how I developed my installation approach and techniques, particularly with regard to the three-way dynamic of the artist:work:viewer relationship and how it can encourage …

Sensible Nonsense, Timothy J. Woodbrey

Theses and Dissertations

“Truth happens only by establishing itself in the strife and the free space opened up by truth itself. Because truth is the opposition of clearing and concealing, there belongs to it what is here called establishing.”[i]—Martin Heidegger

All things contain their own individual existence. When I look at objects I notice material, tradition, individual history. These are starting points for my imagination to seed and germinate. My ideas are fragmented, nonlinear and nonsensical to others but they hold honesty to me. Honesty is powerful and is worth sharing.

This document is an examination of my work during …

Perceptions Of The Homeless Toward Nonprofit Human Service Provider, Lequan M. Hylton

Theses and Dissertations

As the debate intensifies regarding developing remedies to meet the needs of America’s homeless, one solution is for governmental agencies to collaborate with and employ organizations from the nonprofit sector to assist with the needs of the homeless population. Included in the nonprofit sector, faith-based organizations (FBOs) have historically been a source of debate and contention in terms of collaborations with the government. However, Presidents Reagan, George H. Bush, Clinton, George W. Bush, and Obama have embraced the idea of including FBOs in the pool of service providers offering human services. In the Richmond, Virginia region, FBOs and nonreligious nonprofit …

Fast Online Training Of L1 Support Vector Machines, Gabriella A. Melki

Theses and Dissertations

This thesis proposes a novel experimental environment (non-linear stochastic gradient descent, NL-SGD), as well as a novel online learning algorithm (OL SVM), for solving a classic nonlinear Soft Margin L1 Support Vector Machine (SVM) problem using a Stochastic Gradient Descent (SGD) algorithm. The NL-SGD implementation has a unique method of random sampling and alpha calculations. The developed code produces a competitive accuracy and speed in comparison with the solutions of the Direct L2 SVM obtained by software for Minimal Norm SVM (MN-SVM) and Non-Negative Iterative Single Data Algorithm (NN-ISDA). The latter two algorithms have shown excellent performances on large datasets; …

Quantitative Analysis Of 5-Chloro-2-Methoxy-N-[2-(4-Sulfamoylphenyl)Ethyl]Benzamide (Glyburide Analogue, Ga) In Mouse Plasma And Whole Blood Using A Micro-Extraction And Liquid Chromatography-Tandem Mass Spectrometry, Ankit Zalavadia

Theses and Dissertations

Pharmacokinetic evaluation of 5-chloro-2-methoxy-N-[2-(4- sulfamoylphenyl)ethyl]benzamide in mouse plasma demanded for a suitable bioanalytical method. No reported bioanalytical method exists to-date that can quantify concentration of this compound in any biological matrix. The purpose of this study was 1) to develop and validate a new bioanalytical method using a micro-extraction and LC-MS/MS to quantify the target analyte in mouse plasma and 2) to partially validate the method in whole blood. A bioanalytical method was developed and validated in both matrices for a linear concentration range of 2-1000 ng/ml. For both matrices, the reverse predicted concentration of calibration standards (-8.95% to 12.16% …

Conditional Cardiac-Specific Akap13 Knockout Induces Sex Dependent Biventricular Dilated Cardiomyopathy With Sarcomeric And Mitochondrial Defects, Kimberlyn M. Baig-Ward

Theses and Dissertations

Heart disease is a complex and heterogeneous disease. Notably, studies have demonstrated gender differences in the expression and types of cardiovascular disease, such as dilated cardiomyopathy (DCM), a major underlying cause of heart failure. Previously we showed that loss of A-Kinase Anchoring Protein 13 (Akap13), a unique proto-oncogene and estrogen receptor modulator, resulted in enlarged embryonic hearts, defective cardiac sarcomere formation, and embryonic lethality in mice. Data have also shown cAMP-dependent Protein Kinase A (PKA) to be involved in DCM pathophysiology. Given the established role of AKAP13 in cell signaling, its ability to bind and modulate ligand-activated nuclear hormone …

Exploring The Outcomes Of Rehabilitative Care For Veterans And Service Members Treated For A Disorder Of Consciousness In The Vha Emerging Conciousness Program, Janette A. Hamilton

Theses and Dissertations

Over the past several years, there has been an influx in patients being treated for polytraumatic injuries within the Veterans Health Administration (VHA), largely due to the wars in Afghanistan and Iraq, but also due to advances in life sustaining medical interventions. The polytrauma population includes veterans who have sustained a severe traumatic or non-traumatic brain injury, and a significant loss in cognitive and physical functioning, referred to as a disorder of consciousness. The purpose of the current study was to explore factors related to successful emergence from a disorder of consciousness, using a sample of veterans who were treated …

Response Adaptive Randomization Using Surrogate And Primary Endpoints, Hui Wang

Theses and Dissertations

In recent years, adaptive designs in clinical trials have been attractive due to their efficiency and flexibility. Response adaptive randomization procedures in phase II or III clinical trials are proposed to appeal ethical concerns by skewing the probability of patient assignments based on the responses obtained thus far, so that more patients will be assigned to a superior treatment group. General response-adaptive randomizations usually assume that the primary endpoint can be obtained quickly after the treatment. However, in real clinical trials, the primary outcome is delayed, making it unusable for adaptation. Therefore, we utilize surrogate and primary endpoints simultaneously to …

Development Of An Instrument To Measure K-12 Teacher Demoralization In A Test-Based Accountability Context, Heather A. Carlson-Jaquez

Theses and Dissertations

The purpose of this study was to develop an instrument to measure K-12 teacher demoralization. An increasing body of literature has labeled modern education policies as having a demoralizing effect on teachers (Darling-Hammond & Rustique-Forrester, 2002; Noddings, 2004; Ryan & Brown, 2005; Nichols & Berliner, 2007; Santoro, 2011; Hargreaves, Braun, & Gebhardt, 2013). Teacher demoralization has been defined as a teacher’s “inability to access the moral rewards of teaching” (Santoro, 2011, p. 3). Data was collected from a population of K-12 educators through cognitive interviews (n=6) and a large scale data collection analyzed with a principal component analysis …

Catching Up And Staying Out Of Trouble: Serious Juvenile Offenders’ Facility School Experiences And Their Transition To The Community, Lena Jäggi

Theses and Dissertations

Despite recent drops in rates, juvenile incarceration remains a serious issue in the United States (Hockenberry, 2013; Mendel, 2011). One shared part of the incarceration experience across different systems and facility types is the obligation for juvenile offenders to receive correctional education. Ample research demonstrates that increased academic achievement, attending community school, and being employed are connected to better community outcomes and desistance, yet little is known about how school experiences in the facility influences these outcomes. Applying life-course theory of the development of crime (Sampson & Laub, 1997, 2005), the present study investigates whether correctional education serves as a …
