The G-Bdt (Good-Bad Drawings Test): Using Human Figure Drawings With Individuals Who Are Incarcerated, Institutionalized, And/Or In Special Education, George A. Giacobbe, John D. Dooley

Books and Book Chapters

The G-BDT (Good-Bad Drawings Test) is a variation of the psychological projective test known as the Draw-a-Person test (DAP). The DAP requests a drawer to make two drawings: one of a person, and when it is completed and removed, another drawing of a person who is the opposite sex of the person in the first drawing.

There are currently many variations of the DAP including requesting drawings of a person, a house and a tree, drawing a family, a mother and child, or even animals, such as drawing a dog.

The G-BDT requests the drawer draw a person who is …


Adaptive Multi-Label Classification On Drifting Data Streams, Martha Roseberry Jan 2024

Adaptive Multi-Label Classification On Drifting Data Streams, Martha Roseberry

Theses and Dissertations

Drifting data streams and multi-label data are both challenging problems. When multi-label data arrives as a stream, the challenges of both problems must be addressed along with additional challenges unique to the combined problem. Algorithms must be fast and flexible, able to match both the speed and evolving nature of the stream. We propose four methods for learning from multi-label drifting data streams. First, a multi-label k Nearest Neighbors with Self Adjusting Memory (ML-SAM-kNN) exploits short- and long-term memories to predict the current and evolving states of the data stream. Second, a punitive k nearest neighbors algorithm with a self-adjusting …

Humans Are Dust, Chelsea Nanfelt Rowe Jan 2024

Humans Are Dust, Chelsea Nanfelt Rowe

Theses and Dissertations

I probe how objects act as intermediaries between people. These explorations reflect on the delicate navigation that happens when we intertwine our lives with others. My curiosities lie in the fuzzy aura of human life that encircles materials. Do our materials possess life or do we imbue and inject the materials in our world with personalities reflective of ourselves? My motivation for this project is to highlight the stories infused in and witnessed by things we surround ourselves with and use daily.


Stealthy Control Logic Attacks And Defense In Industrial Control Systems, Adeen Ayub Jan 2024

Stealthy Control Logic Attacks And Defense In Industrial Control Systems, Adeen Ayub

Theses and Dissertations

Industrial control systems (ICS) play a crucial role in monitoring and managing critical infrastructure, including nuclear plants, oil and gas pipelines, and power grid stations. Programmable logic controllers (PLCs) are a fundamental component of ICS, directly interfacing with physical processes and implementing control logic programs that govern operations. Due to their significance in controlling critical infrastructure, PLCs often become prime targets for attackers seeking to disrupt these systems. Exploitable vulnerabilities in PLCs render them susceptible to such attacks. While many attacks on PLCs leave a large footprint in network traffic and are detectable by intrusion detection systems (IDS), this dissertation …


Transitions In Patterns Of Substance Use During Early Adolescence: Bidirectional Associations With Externalizing Behaviors, Courtney B. Dunn Jan 2024

Transitions In Patterns Of Substance Use During Early Adolescence: Bidirectional Associations With Externalizing Behaviors, Courtney B. Dunn

Theses and Dissertations

Early adolescents who engage in polysubstance use, defined as the use of three or more different substances, are at particularly high risk of future substance use disorders and adverse psychosocial outcomes. However, little is known about the development of substance use patterns during early adolescence, particularly among youth living in urban settings. Although theory and research suggest that youth with greater externalizing behaviors (e.g., aggression, delinquent behavior) may be more likely to escalate to polysubstance use at an early age, few studies have examined bidirectional relations between externalizing symptoms and polysubstance use. The goal of this study was to (a) …


Prosthetic Attention In Upper Limb Loss: User Experiences, Clinical Perceptions, And Developing Candidate Items, Tanu Bhargava Jan 2024

Prosthetic Attention In Upper Limb Loss: User Experiences, Clinical Perceptions, And Developing Candidate Items, Tanu Bhargava

Theses and Dissertations

The human hand is a powerful tool essential for performing a range of tasks from simple to complex, and it plays a crucial role in social interactions and environmental engagement. Upper limb (UL) loss disrupts these functions and significantly impacts daily life. Prosthetic devices can partially restore these abilities and improve quality of life, but they lack the intuitive control and sensory feedback of natural hands. Consequently, operating a UL prosthesis requires substantial attentional demands, a factor that potentially contributes to high rates of device dissatisfaction and disuse. For UL prosthesis users, managing attentional resources is critical to efficiently controlling …


Developing And Testing A Model Of Discrimination, Internalized Oppression, Mental Health, And Suicidality In Disabled Transgender And Gender Non-Binary (Tgnb) Individuals, Stephanie L. Cull Jan 2024

Developing And Testing A Model Of Discrimination, Internalized Oppression, Mental Health, And Suicidality In Disabled Transgender And Gender Non-Binary (Tgnb) Individuals, Stephanie L. Cull

Theses and Dissertations

Transgender and gender nonbinary (TGNB) individuals experience high rates of discrimination and microaggressions that can lead to internalized cisgenderism and adverse mental health outcomes such as depression, anxiety, and suicidality. Individuals with disabilities similarly experience high rates of discrimination and microaggressions that can lead to internalized ableism and increased adverse mental health outcomes. Although both of these populations have been researched separately, very little extant research has explored the intersections of disabled and TGNB identities. The purpose of this study was to explore a hypothesized pathway leading from microaggressions through internalized oppression and mental health to suicidal ideation within a …

The Splice Index As A Prognostic Biomarker Of Strength And Function In Myotonic Dystrophy Type 1, Marina Provenzano Jan 2024

The Splice Index As A Prognostic Biomarker Of Strength And Function In Myotonic Dystrophy Type 1, Marina Provenzano

Theses and Dissertations

Myotonic dystrophy type 1 (DM1) is a slowly progressive, multisystem disorder caused by a CTG repeat expansion in the DMPK 3’UTR that leads to global dysregulation of alternative splicing. The resulting decline in physical function is slow, and no reliable biomarkers exist for predicting disease progression; however, an RNA mis-splicing biomarker associated with weakness may have utility in predicting functional outcomes. Here we validate the Splice Index (SI) as a potential biomarker of DM1-associated strength and function. Muscle biopsies of the tibialis anterior were collected from DM1-affected individuals at baseline (n = 46) and 3-months (n = 34), along with …

Furthermore, activity recognition in practice needs to account for user trust - models are motivated to enable interpretability, usability, and information privacy. The objective of this dissertation is to improve adaptability and trustworthiness of machine learning models for human activity recognition from bioelectric signals. We improve adaptability by developing pretraining techniques that initialize models for later specialization to unseen …


Moonshine Babies, Arghavan Heydareslam Jan 2024

Moonshine Babies, Arghavan Heydareslam

Theses and Dissertations

Moonshine Babies is a two-screen film made of collage/cut-out stop-motion and live-action. It is a visual poem based on my journals from when I recently started living in the US as an outsider. The experience left me feeling divided between the empty present and memories of the past. suggesting that there are collective memories among a group of interconnected individuals that unite them within a single narrative.

There was a moment when I asked, "If you are your memories, what does it mean to be somewhere you have no memories of and no one has memories of you there?"

The Role Of Notch1 Signaling In Regulating Neurogenesis In The Olfactory Bulb Following Traumatic Brain Injury, Sarah A. Baig

Theses and Dissertations

In the United States, more than 20.5 million adults over the age of 40 suffer from olfactory dysfunction, with TBI attributing to 5-17% of all olfactory dysfunction cases. Although often initially undetected and less conspicuous than other cognitive and behavioral impairments, olfactory dysfunction may have a significant negative impact on patients' quality of life and ability to accomplish activities of daily living, therefore the pathophysiology of these disorders should be understood. The production of neural stem cells enhances the repair and regeneration of the injured brain following a TBI. One of the primary endogenous neural stem cell generation sites in …


Unfolding Remembrance: Folding Islamic Principles Into Pondering Machines, Hind Al Saad Al-Kuwari Jan 2024

Unfolding Remembrance: Folding Islamic Principles Into Pondering Machines, Hind Al Saad Al-Kuwari

Theses and Dissertations

Principles of early Islamic art can be surveyed as a precursor to Western computational art. Though produced in different historical and cultural contexts, Islamic art and computational art are connected by underlying structures—arithmetic, harmony, and the concept of the Infinite.

Islamic developments in knowledge, like algebra, contributed to mathematics and mechanics—the building blocks of contemporary technology. Returning to Islam’s traditional harmony between religion and science, my creative practice constructs machines as an act of worship (ʿibadah), folding Islamic principles into the medium of computation.

Selected verses from the Quran are used as the core of each automaton (self-operating machine). Their …


Intersectionality, Racial Discrimination And Oral Healthcare Utilization Among Black Adults In Baltimore City, Maryland, Briona M. Phillips Jan 2024

Intersectionality, Racial Discrimination And Oral Healthcare Utilization Among Black Adults In Baltimore City, Maryland, Briona M. Phillips

Theses and Dissertations

INTRODUCTION: Oral health is essential for overall well-being, yet disparities persist, particularly among marginalized populations including Black adults. Limited access to and underutilization of oral healthcare services exacerbate these disparities. Discrimination, both individual and systemic, acts as a significant barrier to accessing care, contributing to disparities in oral health outcomes. Individuals facing discrimination experience mistrust and fear within oral healthcare settings, leading to delayed or avoided care. Therefore, investigating and addressing discrimination among Black adults is essential for promoting equitable access to oral healthcare, improving overall oral health outcomes, and lessening existing disparities.

PURPOSE: The purpose of this dissertation was …


Examining The Relationship Between Racism-Related Stress And Coping Among Black Adolescents: A Linked Lives Perspective, Kenna Yadeta Jan 2024

Examining The Relationship Between Racism-Related Stress And Coping Among Black Adolescents: A Linked Lives Perspective, Kenna Yadeta

Theses and Dissertations

As Murry and colleagues (2018) note, racism serves as a family-level stressor, impacting both Black adolescents and their parents. As Black teens continue to experience frequent and varied racism experiences (English et al., 2020), their Black parents are facing a double challenge: bearing the weight of their own experiences with racism, while also parenting a Black adolescent through the same. Recent frameworks (e.g., Gilligan et al., 2018) highlight the linked experiences of Black families, in dealing with their stress and coping. As such, the current study aimed to explore the ways that both adolescent and parental experiences with racism related …

Effects And Mechanisms Of Smartphone-Based Mindfulness Training On Emotional Experience, Polina Beloborodova Jan 2024

Effects And Mechanisms Of Smartphone-Based Mindfulness Training On Emotional Experience, Polina Beloborodova

Theses and Dissertations

Emotional well-being is an important component of mental and physical health that includes both positive emotions and an absence of emotional symptoms (e.g., depressive- and anxiety-related). In this study, we examine psychological mechanisms that help to explain the effects of an digital mindfulness-based intervention (MBI) on emotional states. We conducted a randomized controlled trial wherein undergraduate student participants vulnerable to decreased positive and increased negative affect received a 2-week smartphone-based MBI or a structurally equivalent coping control intervention. Emotional experience, including depressive feelings, anxiety, and happiness, as well as subjective social well-being, including loneliness and felt connection to others, was …


Trans And Gender Diverse Inclusion In Academic Library Hiring, Keahi K. Adolpho, Stephen G. Krueger, Luke Sutherland, Adrian Williams Jan 2024

Trans And Gender Diverse Inclusion In Academic Library Hiring, Keahi K. Adolpho, Stephen G. Krueger, Luke Sutherland, Adrian Williams

VCU Libraries Faculty and Staff Publications

We do not know how many trans and gender diverse people work in libraries in the United States. Like the US Census, the American Library Association’s demographic survey of its members (which is by no means a complete or accurate representation of the profession) asks if respondents are male or female (Rosa & Henke, 2017). In addition to erasing anybody who is not one of these two things, this question does not provide information on whether respondents are trans or gender diverse. And yet, we are here: all four of the authors of this chapter are trans people who work …


Family Rejection And Affirmation Experiences Among Racially And Ethnically Marginalized Youth Who Identify As Transgender And/Or Gender Diverse, Angela Matijczak Jan 2024

Family Rejection And Affirmation Experiences Among Racially And Ethnically Marginalized Youth Who Identify As Transgender And/Or Gender Diverse, Angela Matijczak

Theses and Dissertations

Relationships with family members can be a vital source of support, and significant stressor, that contributes to mental health outcomes among transgender and gender diverse young adults who are racially and ethnically marginalized (TGD REMY). Guided by a life history narrative approach, this qualitative study explored family affirmation and rejection among TGD REMY across three aims: (a) how TGD REMY define their experiences of family rejection and/or affirmation, (b) whether and how experiences of rejection/affirmation change throughout the lifetime, and (c) whether and how experiences of rejection/affirmation differ by each family member. Semi-structured interviews were conducted with 17 TGD REMY …


Identifying Mechanistic Pathways To Rigidity Associated With Obsessive-Compulsive Personality Disorder Traits Using A Novel Decision-Making Paradigm, Hannah L. Heintz Jan 2024

Identifying Mechanistic Pathways To Rigidity Associated With Obsessive-Compulsive Personality Disorder Traits Using A Novel Decision-Making Paradigm, Hannah L. Heintz

Theses and Dissertations

Cognitive and behavioral rigidity is observed across several mental disorders and is a defining characteristic of Obsessive-Compulsive Personality Disorder (OCPD), a highly prevalent and debilitating, yet understudied, disorder. In particular, treatments for OCPD are underdeveloped due to our poor understanding of the mechanisms leading to the disorder’s key feature of rigidity. Two related disorders, anorexia nervosa (AN) and obsessive-compulsive disorder (OCD), have shown distinct mechanistic pathways leading to symptoms of rigidity, indicating that this trait can arise as a result of a number of differentially impaired cognitive processes, each requiring unique interventions. To examine the relationship between symptoms of OCPD …
