The continent of Africa is considered a developing region due to the high rate of poverty and lack of infrastructure, and China has stepped up to offer loans to countries in need across the continent. The billions of dollars in loans that China has widely distributed among African countries raises serious concerns. Angola and Zambia are two countries in Africa considered as developing nations. The two countries, in dire need of infrastructure, have desperately sought loans from the Chinese government. Chinese loans have become common among nations even though respected international financial institutions warn against the hidden conditionalities that are …

African American English As A Predictor Of Ethnic And Ethnolinguistic Identity In Adolescence, Giahna L. Glasco

Dissertations and Theses

This study’s purposes were to provide support for the Social identity theory of African American English (Vietze & Glasco, 2022) and the meanings African American English (AAE) speakers assign to their dialect. The study was primarily based on Tajfel’s (1979) social identity theory that proposes individuals derive a sense of self from group membership. The qualitative analyses examined ethnic and language group memberships. Ethnic identity development (Phinney, 1992), and ethnolinguistic identity theories (Giles and Johnson, 1987) guided narrative and content analyses of Kiese Laymon’s memoir, Heavy: An American Memoir (Laymon, 2018). The sample included 21 African American English conversations …

Psychedelic Use And Psychological Flexibility: The Role Of Decentering, Mystical Experiences, Ego-Dissolution, And Insight, William M. Campo

Therapeutic Considerations For The Polycule: A Qualitative Exploration Of Consensual Non-Monogamy In Couples Treatment, Tema Watstein

Dissertations and Theses

Despite the growing visibility of consensual non-monogamy culturally and in the academic domain, treatment of CNM relationships has been understudied from the clinical perspective. This study utilized a sample of 11 clinicians, who discussed their experiences of treating non-monogamous couples through a semi-structured interview. Qualitative thematic analysis led to the emergence of robust themes, which were synthesized into three broader categories: 1. Therapeutic Process, 2. Issues in Treatment, and 3. The Meaning of Non-Monogamy. Therapists discussed their own clinical processes, with emphasis on countertransference, frame, self-disclosure, and considerations for training. Themes also emerged surrounding common issues in treatment, ranging from …

Dissertations and Theses

Identification of ADHD and Comorbid Disorders in Children: The potential role of minority group membership

by

Rachel Tayler, MSc, MA

Advisor: Sarah O’Neill, PhD

Attention-Deficit/Hyperactivity Disorder (ADHD) affects six million US children. Females, Latinx, and possibly Black children have lower rates of diagnosis than their Male and White non-Latinx peers. ADHD is behaviorally defined, and as such, clinicians' perceptions of symptoms and determination of diagnoses may be influenced by demographic factors such as race, ethnicity and sex.

This vignette study examined whether clinicians' implicit ethnic, racial, and sex biases affect diagnosis of ADHD and comorbid conditions. Psychiatry trainees and pediatricians …

Design And Control Of Quasi-Direct Drive Actuation For Lightweight And Versatile Wearable Robots, Shuangyue Yu

Dissertations and Theses

Wearable robots have shown great potential for augmenting the physical capabilities of humans in lab settings. However, wearable robots for augmenting the physical capabilities of humans under community-based conditions are the new frontier of robotics. Furthermore, the design and control are still considered to be grand challenges for providing physical augmentation for humans. In terms of design, the state-of-the-art exoskeletons are typically rigid, bulky, and limited to lab settings. In terms of control, most of the rhythmic controllers are not versatile and are focused only on steady-state walking assistance.

The motivation behind my research is to improve both the design …

Understanding The Relationship Between Urban Areas And The Boundary Layer Using Remote Sensing Methods, Gabriel A. Rios

Dissertations and Theses

The atmospheric boundary layer is crucial to the exchange in energy between the Earth's surface and the atmosphere. Within this layer, the majority of human activities are carried out, which makes understanding the boundary layer especially important for many of our interests. A key component of this energy exchange is found at the surface, was surface properties are the interface through which momentum, heat, moisture, and other fluxes are transferred between media. Not only does the surface act as an interface, but as an actor that influences the exchange efficiency and rates. This concept is the crux of atmospheric boundary …

Modulation Of Brain Tissue Transport And Endothelial Glycocalyx And Tight Junctions Of The Blood-Brain Barrier By Transcranial Direct Current Stimulation, Yifan Xia

Dissertations and Theses

Transcranial direct current stimulation (tDCS) is a non-invasive approach to treat a broad range of brain disorders and to enhance memory and cognition in healthy individuals. In addition to directly acting on neurons by modulating the membrane potential, inducing neuronal polarization and changing cortical excitability in the brain to achieve its therapeutic effects, prior studies found that tDCS can transiently enhance the permeability (P) of the blood-brain barrier (BBB), the interface between blood circulation and brain tissue. Brain extracellular space (ECS) is a narrow microenvironment which surrounds every cell in the central nervous system (CNS). ECS occupies ~20% of brain …

Osseointegration Of A Cementless Total Knee Arthroplasty In A Murine Model Of Glucocorticoid Induced Osteoporosis, Elexis C. Baral

Dissertations and Theses

Glucocorticoid-Induced Osteoporosis (GIOP) is the second largest cause of osteoporosis worldwide. Glucocorticoid-Induced osteoporosis is rapidly, driven principally by deficient osteoblast activity (i.e., decreased bone formation) rather than increased osteoclastic activity. Glucocorticoid-type steroids (GC) are used long-term typically for inflammatory diseases such as rheumatoid arthritis, lupus, multiple sclerosis, and other autoimmune disorders. Inflammatory arthritis often leads to joint replacement at relatively young ages. However, patients who are on GC treatment appear to have poorer outcomes for total joint arthroplasty compared to healthy patients. This is thought to be due to the anti-anabolic effects of GCs and impaired bone healing and osseous …

Wave Engineering In Time Modulated, Nonlinear, And Anisotropic Metamaterials, Ahmed Mekawy

Dissertations and Theses

Leveraging wave matter interactions is central to a myriad of electromagnetic wave-based applications. During the past decades, research on extreme wave manipulation has been revolutionized by artificially engineered materials (metamaterials) and by adding new aspects to the wave-matter interactions that showed intriguing results inaccessible in conventional linear, time invariant (LTI), passive and isotropic media. In this work, I will explore, numerically and experimentally, the possibility of realizing devices that perform beyond or close to their fundamental LTI limitations by adding periodic modulation, nonlinearity, and gain. I will demonstrate these concepts at radio frequencies (RF) and at optical frequencies. Specifically, at …

Since people were indoors during the pandemic, individuals took to social media and left comments on YouTube about bullying. Since people could not discuss bullying in-person, it was interesting to see how people shared their views on bullying and cyberbullying via YouTube, as well as how that might have changed after the start of COVID-19. The purpose of this study is to demonstrate how social media platforms like YouTube provide a safe space …

Discrimination Against Veiled Women In The West: Social Isolation, Amina M. Abdallah

Dissertations and Theses

This research examines the discriminatory practices faced by veiled women in the West that impede their integration into their local communities or lead them to feel socially isolated. Societal prejudice and, in some cases, the laws of the land often solidify this isolation of Muslim women and girls from the rest of the world. These victims of social oppression face discrimination based on multiple factors, such as their religion, race, and sex.

This study analyses preconceived notions regarding veiled women, incorporating evidence from seventeen qualitative interviews done with veiled Muslim women residing in the West, particularly the United States, United …

Joint Laughter Between Patient And Therapist: Exploring The Function Of These Moments And Their Relationship To The Working Alliance In Short-Term Psychotherapy, Molly Rappaport

Dissertations and Theses

Laughter emerges in infancy and reflects mutually aroused and regulated positive affect within the caregiver-infant relationship and repeated cycles of shared, co-regulated positive arousal have been shown to play a critical role in fueling secure attachment bond formation and laying the groundwork for the infant’s capacity for affect regulation (Schore, 2003). Throughout life, laughter continues to function as an attachment behavior with the possibility of promoting interpersonal closeness or creating distance. Attitudes toward the role of laughter in psychotherapy vary among psychodynamically-oriented clinicians and research has mostly focused on the kinds of humor and interventions that provoke laughter rather than …

Holistic Treatment: A Qualitative Study Of The Integration Of Chinese Medicine With Psychoanalysis In China, I. Wang

Dissertations and Theses

With its fundamental principle of body-mind unity, Chinese medicine has long been regarded as one of the most influential bedrocks of holistic treatment. Given its prevalence in China, Chinese medicine (CM) is a culturally appropriate way for therapists in China to integrate with psychoanalysis. This qualitative study investigates how Chinese psychotherapists in China with Western psychanalytic backgrounds synthesize the principles and methods of CM into their practice. Further, the barriers and facilitators to the integration are also examined. With a sample of twelve Chinese psychotherapists in China primarily trained at The China American Psychoanalytic Alliance, through semi-structured interviews, therapists' integration …

Through analysis and research the following is found: the occurrence of global conflict is accelerating alongside an increase in the severity of organized violence dynamics; global authoritarianism is expanding presenting a threat to global freedoms and liberal democracy; as these trends are occurring, world hunger is steadily on the rise reflecting a significant backsliding of progress achieved …

Ego-Feeling And Ego-Boundaries: An Examination Of The Work And Legacy Of Paul Federn, Samuel Selinger

Dissertations and Theses

Paul Federn was an important figure in the early development of psychoanalysis. He was, besides Sigmund Freud himself, the only founding member of the Vienna Psychoanalytic Society who was still a member when the society was disbanded by the Nazis in 1938. He was also an early pioneer in the use of psychoanalysis toward the understanding and treatment of psychosis, and was among the very first to consider the importance of the ego to psychoanalytic understanding of the mind and mental illness. This dissertation examines Federn’s key ideas-- ego-feeling and ego-boundaries-- their influence on later psychoanalytic formulations by Winnicott, Lewin, …

Exosome- And Microrna-Based Therapeutic Approach For Tendinopathy, Angela Wang Ilaltdinov

Dissertations and Theses

Tendinopathy, characterized by degeneration and chronic inflammation, is a significant clinical burden. Current treatments focus on symptom management but do not sufficiently address its underlying pathology; however, stem cell-based approaches aimed at repairing diseased tissues may overcome this limitation. Therapeutic effects of stem cells may be due in part to paracrine actions, including some mediated by exosomes – extracellular vesicles secreted by cells that play a role in cell communication. MicroRNA (miRNA), small non-coding RNA carried by exosomes, are likely responsible for many exosome effects. Exosomes and miRNA therapies show promise in treating diseases such as cancer and arthritis, but …

The (Pfas)T And The Furious: Applying Hazardous Waste Management Frameworks To The Global Presence Of Pfas, Maggie Clark

Journal of Air Law and Commerce

International treaties governing transboundary hazardous waste are a result of the theory of sustainable development. These conventions have developed over several decades but still lack authority over one of the biggest waste exporters: the United States. As forever chemicals like GenX become a spotlight for future waste regulation, can these conventions project a framework to apply to the currently unregulated chemical that predominantly travels across the Atlantic Ocean between the Netherlands and the United States? This Article seeks to apply various transboundary waste international laws to the market for GenX, identify problems, and propose solutions.
