Approaching Trans Debates As Fascistic Sites Of Engagement., Sarah Jump

Electronic Theses and Dissertations

For the past decade, trans rights issues have been a legal topic of discussion and are still discussed publicly in 2021. This thesis researched how arguments surrounding anti-trans issues were successful in the United States. The arguments surrounding these issues are important to study to see how they pass within society and if traditional rules of argumentation are changing. This thesis proposes that traditional dialectical argument is no longer occurring and has taken a post-dialectical turn. The purpose of this thesis is to describe the kinds of arguments used in these issues and build the case that they are evidence …

Concurrent Reporting Of Adverse Childhood Experiences Among Perspectives Of Adolescents And Caregivers., Katie J. Berghuis

Electronic Theses and Dissertations

The consequences of Adverse Childhood Experience (ACE) events in youth have predominantly been studied through retrospective studies that assess adults’ first 18 years of life or caregiver report of ACEs in youth. Reliance on only caregiver report to discern ACEs is a limitation amongst prior studies as research has found that caregivers tend to underestimate ACEs among their children, and there is even a greater discrepancy of reporting between caregivers and youth 12 years and older. Therefore, this study investigated concurrent reporting of self-report ACE scores in adolescents – defined in this study as 12 to 20 years old – …

Electronic Theses and Dissertations

This dissertation is an examination of Arab and South Asian American men’s (1) experiences and perceptions of discrimination and belonging in two non-traditional immigrant destinations in the United States (U.S.) south, and (2) their performance of masculinities in response to Muslim women’s experiences with Islamophobia. I use intersectional theory, theories of race and racism, theories of gender, theories on belonging, and grounded theory to analyze 23 qualitative semi-structured interviews with Arab and South Asian men who live in one large city and one rural town in the U.S. south. I find that upper-, middle-, and working-class Arab and South Asian …

Framing The Guard: A Content Analysis Of How The News Media Frames The National Guard During Times Of Crisis., Taylor L. Tolles

Electronic Theses and Dissertations

A quantitative content analysis of 585 newspaper articles gathered from seven news sources that covered the National Guard’s response to COVID-19, BLM Protests, and the Capitol Riot were used to determine the prevalence of frames used to depict the Guard during times of crisis. By using the five frames found in media framing (Entman, 1991), the prevalence of frames found in newspaper media was compared to the prevalence of frames found to be used in times of crisis (Semetko & Valkenburg, 2000). The results showed that even though the Guard’s response in times of crisis is similarly framed as previous …

RNA-based therapeutics is a rapidly expanding field due to its enormous potential for treatment of diseases through knockdown of genes or expression of therapeutic proteins. However, due to the overall negative-charge of an RNA molecule, RNA-based therapeutics must rely on delivery systems to overcome the various biological barriers for ultimate release of an RNA payload into the cytosol. Over the past three decades, the development of lipid-based RNA delivery systems, especially lipid nanoparticles (LNPs), have been comprehensively studied due to their unique properties. LNPs represent the most widely used delivery systems for RNA-based therapeutics, as evidenced by the clinical approvals …

Aggregation Dynamics Of Bulk Nanoparticle Haloing Systems And The Influence Of Non-Ambient Temperatures., Marzieh Moradi

Electronic Theses and Dissertations

One of the methods of assembling colloids into 3D crystal structures is through the use of nanoparticle haloing. Nanoparticle haloing is a stabilization mechanism in binary particle suspensions possessing both a size and charge asymmetry, with which the nanoparticles aid in the bulk suspension’s stability. By altering the volume fractions of nanoparticles, it is possible to control the effective repulsion between the microparticles. Understanding the colloidal interactions and aggregate crystallinity as a function of nanoparticle concentration, temperature, and time are key challenges in developing future materials and designing crystalized 3D colloidal systems. In this study, we investigated the effect of …

Exploring Meerwein-Ponndorf-Verley Reactions Using Metal Organic Framework Catalysts., Yuehan Zhou

Electronic Theses and Dissertations

The Meerwein–Ponndorf–Verley (MPV) reaction is a reaction that is used to reduce aldehydes and ketones to the corresponding alcohols with the added use of catalysts. The common metal triflate catalysts used in MPV reduction incur tremendous environmental hazards and high operational costs. The use of Metal-Organic Frameworks (MOFs) as catalysts can be an alternative due to MOFs’ extraordinarily high surface areas, ultrahigh porosities, tunable pore sizes, modifiable internal surfaces, and numerous framework structures. Moreover, using MOFs as catalysts for MPV hydrogenation is economically viable due to low operational and material costs. This study involves using MOF-808 (Hf) in the MPV …

Electrical Characterization Of Phytoplankton Suspensions Using Impedance Spectroscopy., Margaret R Jett

Electronic Theses and Dissertations

Phytoplankton are closely monitored because of their important environmental role, and the impacts they have on their local ecosystems. Some phytoplankton respond to stress by producing lipids, which can be harvested for biofuels and other chemicals. Microfluidic devices have been important in improving the portability and throughput of phytoplankton characterization methods, increasing their potential for in situ use. This study utilized a small sample of phytoplankton suspended in a stagnant medium and measured the impedance response using a lab-on-chip and impedance analyzer. The individual cell characteristics were derived from the impedance response of the group. The goal was to characterize …

Interpersonal Needs And Suicide Risk: Examining Indirect Effects Of Internal Hostility And Feeling Forgiven, Kelley C. Berto

Electronic Theses and Dissertations

Suicide is a national public health concern, and unmet interpersonal needs (i.e., perceived burdensomeness, thwarted belongingness) may contribute to enhanced risk. However, mechanisms of action and certain protective variables are not well understood. The present study examined simple mediation models, with internal hostility as a mechanism of action between interpersonal needs and suicide risk. Additionally, our study examined the moderating role of various aspects of receiving forgiveness on the association between interpersonal needs and internal hostility in these simple mediation models. A community-based convenience sample was surveyed (N=712). Our findings indicated that internal hostility partially mediated the association …

Endothelial Heat Shock Protein A12b And Yes-Associated Protein Cooperatively Promote Angiogenesis Following Myocardial Infarction, Min Fan

Electronic Theses and Dissertations

Heart failure after myocardial infarction (MI) remains the leading cause of mortality among all cardiovascular diseases globally. Angiogenesis plays a critical role in cardiac functional recovery after MI. Heat shock protein A12B (HSPA12B) is predominately expressed in endothelial cells and required for angiogenesis. Yes-associated protein (YAP) has been reported to promote tumor angiogenesis.

In the present study, we investigated the cooperative role of HSPA12B and YAP in angiogenesis following myocardial ischemic injury. Endothelial specific deficiency of HSPA12B (eHspa12b^-/-) or YAP (eYap^-/-) impairs angiogenesis and exacerbates cardiac dysfunction after MI, when compared with wild type …

Positive Body Image And Cognitive Processing Style, Brittney Dumas

Electronic Theses and Dissertations

Social media use among young people is ubiquitous and has been associated with body image concerns. Though prior work has overwhelmingly focused on “screen time,” increasing evidence highlights the role of subjective social media experiences in driving this association, rather than mere frequency of use. In the current study, body appreciation was tested as a trait-level variable that may protect women from the negative impact of appearance-focused fitspiration images, which have become common in social media platforms. Appearance schema activation and appearance-related self-discrepancy were examined as two social-cognitive processes in which self-protective tendencies may emerge. Fitspiration exposure predicted appearance schema …

Medication Versus Brain-Based Treatment: Evaluation Treatment Preferences Of Parents Of Children With Adhd, Rebecca Recio-Swift

Electronic Theses and Dissertations

Attention-Deficit/Hyperactivity Disorder (ADHD) is one of the most prevalent neurodevelopmental disorders across the world. Currently, treatment for ADHD mostly consists of either medication or behavioral therapy or a combination of both. However, research has shown that medication used as therapy for the treatment of ADHD has side effects which parents deem undesirable for their children. Therefore, recent research has focused on patient and parent preferences. Studies have found that behavioral or other treatment options may often be chosen over medications. These same studies have documented the characteristics of parents that prefer certain treatments for their children. The purpose of this …

Hot Or Not? The Effects Of Fitspiration Images On Body Dysmorphic Concerns, Kayla Ramsey

Electronic Theses and Dissertations

Despite positive intentions, research suggests that fitspiration causes a multitude of negative effects on body image. This study will expand on previous work by examining the effects of fitspiration on body dysmorphic concerns, appearance-based rejection sensitivity (appearance-RS), and intentions to exercise, as well as the differences in these effects by sex. The first hypothesis is that participants will report more body dysmorphic concerns and appearance-RS following exposure to fitspiration compared to travel images. Second, it was hypothesized that compared to males, females will be more prone to the negative impact that fitspiration images have on body dysmorphic concerns and appearance-RS. …

Critical Thinking In Law Enforcement Training Academies: A Phenomenological Study Of Officer Experiences, Billy J. Spruill

Electronic Theses and Dissertations

Recently, law enforcement officer use of force incidents resulting in death has seemingly become more prevalent. Generally, the educational requirement for a law enforcement officer is a high school diploma or general education development degree. One must question if this requirement is sufficient for a law enforcement officer to be successful in a modern world as the law enforcement training academy may be the law enforcement officer’s only postsecondary education. Critical thinking is a needed skill identified by high-stress professions such as the military, nursing, and disaster management, yet there is limited study regarding critical thinking in law enforcement. The …

Targeting The Mek5, Mek1/2, And/Or Pi3k Pathways To Reverse Epithelial To Mesenchymal Transition And Enhance Chemotherapeutic Sensitivity In Breast And Brain Cancers, Akshita Bhatt

Electronic Theses and Dissertations

Triple-negative breast cancer (TNBC) is the most aggressive form of breast cancer and accounts for 10-15% of breast cancer cases. Due to absence of estrogen, progesterone, and human epidermal growth factor receptors, there is lack of targeted therapies and chemotherapy remains the mainstay treatment. Moreover, drug resistance is a major problem associated specifically with TNBC. Similarly, while estrogen receptor positive (ER+) breast cancer can be treated with targeted therapies such as tamoxifen, 40% of patients develop resistance and resulting in recurrence of the disease.

There is a dire need for identifying novel targets and developing therapeutics to target triple-negative and …

Predicting Covid-19 Behavior: Is It All Due To Political Orientation?, Caleb Potts

Electronic Theses and Dissertations

ABSTRACT

Adherence to COVID-19 preventing measures is becoming increasingly important as governments across the world realize COVID-19 is not an acute, but a chronic problem. There is, however, disagreement over to what extent COVID-19 is a problem. In the United States, the division appears to be primarily along party lines (Democrat and Republican[1]), though even within parties there is division. This division might be explained by differences in: the behavioral immune system and trust in government. Additional factors to examine include: personality, fear of COVID-19, and religious beliefs. The present study used previously validated self-report measures to assess …

Unicorns Are Not Real And Neither Are You: Peter S. Beagle's Postmodern Fairy Tale, Athena Hayes

Electronic Theses and Dissertations

Although considered by many readers to be a “cult classic,” Peter S. Beagle’s 1968 novel The Last Unicorn has been unrepresented in literary scholarship. Many fantasy critics in the past have dismissed the work as lacking a sense of reality through its mixing of modern language with a medieval, fantasy setting. However, the novel’s purposeful muddling of reality raises questions of ontology and the nature of storytelling/world-projection. The objective of this study is to not only to act as a sort of apologetic for The Last Unicorn, but also read the novel in the context of fairy tale/mythic studies …

You Are Not Welcome Here: Sloterdijk’S Posthumanism And The Rhetoric Of Hostile Urban Architecture And Design, Brandon William Aungst

Electronic Theses and Dissertations

This dissertation brings together three scholarship areas: rhetorical theory and analysis, hostile urban architecture and design, and Sloterdijk’s version of posthumanism. I synthesize these complementary areas to address the following questions: How do architecture and design contribute to the rhetorical meaning-making of being human and facilitate the communication of that meaning to others? How do different types of architecture and design produce the material contexts for conceptualizing what humanness means and contribute to the development of fore-structures for interpreting and communicating that humanness (e.g., hostile architecture and barbed wire)? How can we conceptualize various types of architecture and design, or …

Detecting A Heterogenous Sample Of Pigmented Melanoma Cell Lines Using Photoacoustic Flow Cytometry, Margaret Cappellano

Electronic Theses and Dissertations

Metastatic melanoma is the deadliest form of skin cancer, which is in part, attributed to its rapid aggression and lack of response to typical treatment methods. There are far too often cases where a lymph node biopsy does not detect the severity of the cancer, which in turn causes a lack of diagnosis until a mass can be visually detected on a scan, such as a PET, CT, or MRI. Once visible on a scan, the cancer is too progressive for successful treatment. To avoid this, we investigated how a blood sample can be used to negate a missed diagnosis, …

Justice, Human Dignity And The Capabilities Approach: A Moral Assessment On Ghana’S Health Care Delivery System, Paul Eliud Esibu

Electronic Theses and Dissertations

Life and quality healthcare delivery are central parts of the well-being of the human person. However, despite the political and socio-economic the successes that Ghana has chalked in pre-colonial, colonial and contemporary times, the quality of healthcare delivery in Ghana could be described as sub-standard. In this a context, the Capabilities Approach, “The Theology of the Body” and the Akan indigenous understanding of the human person emerge as an integrated formidable tool to enhancing life and quality healthcare as central part of the human person. This is because “The capabilities approach – in both its comparative and it’s normative version …

Quantification Of Persistent Organic Pollutants In Various Matrices Using Stir Bar Sorptive Extraction And Isotope Dilution Mass Spectrometry, Weier Hao

Electronic Theses and Dissertations

A method was developed to quantify persistent organic pollutants (POPs) in a wide range of matrices including wastewater, dietary supplements, and human whole blood using stir-bar sorptive extraction, GC-MS/MS, and isotope dilution mass spectrometry (IDMS). The method enabled accurate, precise, sensitive, and efficient quantification of POPs in these matrices. Compared with calibration curves, IDMS provided measurements with a higher level of accuracy and precision, especially at lower measured concentrations. The use of GC-MS/MS enabled a lower limit of quantification compared with GC-MS. A reverse-IDMS method was performed to further eliminate biases from the labelled concentrations of the commercially available standards. …

Characterizing The Dormancy And Repair Of A Circumneutral Passive Remediation System Receiving Iron And Sulfate-Rich Amd, Garrett Struble

Electronic Theses and Dissertations

The Wingfield Pines remediation system is a ~20-acre circumneutral, gravity-fed system constructed in 2009 to passively remediate Fe from an ~2000 gallon/minute effluent. In 2017, a fracture to the system’s underground cavern caused the AMD effluent to bypass the system, flowing directly into Chartiers Creek and leaving the system decommissioned between 2017-2019. Soil slurry and water samples were collected in the weeks prior to the system’s reinstalment in September 2019 through January 2020 in order to determine the effect of the repair on remediation efficiency and microbial community composition. This study acted as the first to describe the temporary decommissioning …
