Observation Of New Particle Formation In The Northern Hemisphere At Altitude From 4 To 20 Km, Mohamed Saad

Electronic Theses and Dissertations

New particle formation (NPF) is investigated using measurements of aerosol size distributions and meteorological variables made in two continents, including USA and Europe. Despite the considerably different aerosol particle abundances among the sites, a common relationship was found between the characteristics of NPF events and the air mass convective and/or advective transport. CO and O3 act as tracers of tropospheric and stratospheric air, respectively, their statistical relationship can be used to quantify air mass characteristics and origins. The mixing ratio values of CO increased within the upper troposphere layer before/during NPF events, which may serve as an indicator of occurring …

Twentieth Century Pandemic Narratives And Mental Health Discourse, Kristy R. Barraza

Electronic Theses and Dissertations

This paper utilizes René Girard’s theories concerning plague literature to examine twentieth century pandemic novels’ engagement with mental health discourses surrounding anxiety and melancholia. Girard argues that plague literature consists of four main elements: contamination, dissipation of differences, doubles, and sacrifice; he also argues that the plague represents violence. In 1918, a plague of influenza killed more people in the United States than all the wars from the twentieth century combined. William Maxwell’s They Came Like Swallows and Katherine Anne Porter’s Pale Horse, Pale Rider depict the trauma caused by the 1918 pandemic; Maxwell shows how the 1918 influenza disrupted …

The Place And Role Of Pharmacy Benefit Management (Pbm) Companies In Us Healthcare System, George Mattis Ii

Electronic Theses and Dissertations

On average, prescription drugs cost US consumers more than any other developed country in the world. US drug makers claim that intermediaries in the prescription drug supply chain, companies called pharmacy benefit managers (PBM), are forcing them to increase their drug prices. PBMs counter that the discounts they receive from drug makers are channeled to insurers. This thesis will examine the role that PBMs play in the prescription drug supply chain and determine what effect they have on drug prices. This thesis will utilize a comparative static model, Structure, Conduct, Performance (SCP) framework to analyze the pharmaceutical manufacturing and the …

Parental Self-Efficacy, Parenting Stress, And Mental Health Among Latina Mothers Of Young Children, Thania Galvan

Electronic Theses and Dissertations

Parenthood can increase the risk for mental health concerns, especially for Latina mothers. Poor maternal mental health can result in significant negative maternal and child outcomes, particularly if a mother’s mental health needs go unmet. In an attempt to better understand the factors that impact Latina mother’s mental health, this study explored the relations among parental self-efficacy, parenting stress, and mental health. It also explored mother’s self-reported resource availability and sociocultural factors as potential modifiable points of interventions in these relations.

Methods: The study was conducted using data from 132 Latina mothers that participated in a larger project examining stress …

So What, Now What? Using Social Media Activism To Inform Power-Conscious Prevention Of Gender-Based Violence, Andrea R. Thyrring

Electronic Theses and Dissertations

We will not end gender-based violence by responding to it. Experts and national organizations agree that effective primary prevention programs are essential to stopping harmful behaviors before they start (DeGue et al, 2014; American College Health Association, 2016; American College Health Association, 2018; Townsend, 2017; Schneider & Hirsch, 2018; McMahon et al, 2019), so much so that primary prevention to address gender-based violence on college campuses has been mandated by state and federal policy (SB 19-007, 2019; Institutional Security Policies and Crime Statistics, 2020). In order to be effective, primary prevention programs should be tailored to the community in which …

The Social Determinants Of Diabetes And Coronary Heart Disease In South Asian American Immigrants, Mishal Ayaz

Electronic Theses and Dissertations

An astounding 20% of South Asian Americans have diabetes (Matthews and Zachariah 2008). Conventional risk factors for coronary heart disease includes: age older than 65, sedentary lifestyle, cigarette smoking, hypertension, elevated low-density lipoprotein (LDL), cholesterol, and type 2 diabetes, all factors beyond health care (italicized for emphasis) (Mathews and Zachariah 2008). But conventional risk factors alone are not sufficient to predict the alarmingly high rates of coronary heart disease (“CHD”) for South Asian Americans. In fact, the only conventional risk factor more prevalent in this community than others is diabetes. So, the question remains, what factors are contributing to the …

“But I’M Not Racist”: How Implicit Racial Bias, Feedback And Racial Affective States Impact Clinical Judgment In Mental Health Treatment, Dhriti Tiwari

Electronic Theses and Dissertations

Implicit bias has gathered research interest in healthcare, yet remains less directly examined in the mental health field (Merino et al., 2018). Mental health providers can continue to be influenced by implicit bias despite higher ratings of cultural competence (Boysen, 2010). The purpose of this study was to supplement the limited research examining the impact of implicit bias on the clinical judgment process. The study aimed to examine whether: 1) implicit race bias scores were related to diagnostic impressions, 2) feedback about implicit bias was related to diagnostic impressions, and 3) racial affect mediated the relationship between receiving feedback and …

Evaluation Of The Effect Of The Clinical-Decision-Support Systems On Diabetes Management: A Multivariate Meta-Analysis Comparison With Univariate Meta-Analysis, Abdelfattah Elbarsha

Electronic Theses and Dissertations

The advantage of using meta-analysis lies in its ability in providing a quantitative summary of the findings from multiple studies. The aim of this dissertation was first to conduct a simulation study in order to understand what factors (sample size, between-study correlation, and percent of missing data) have a significant effect on meta-analysis estimates and whether using univariate or multivariate meta-analysis would produce different estimates.

The second goal of this study was to evaluate the effect of clinical decision support systems CDSS on diabetes care management by conducting three separate univariate meta-analyses and one multivariate meta-analysis. CDSS are health information …

“It's Like A Phantom Limb. It Feels Like It’S There. It's Supposed To Be There, But It's Not.”: Birthmothers’ Metaphors Of Ambiguous Loss, Melodee Lynn Sova

Electronic Theses and Dissertations

Birthmothers are a population with unique experiences and challenges. Among those challenges is the difficulty understanding and managing a loss for which they do not have a readily available coping strategy. As a birthmother, the author of this dissertation was uniquely situated to connecting with, and understanding the ways in which, birthmothers expressed their narratives. The purpose of this dissertation is to explore the ways in which birthmothers make sense of their experiences with ambiguous loss by examining the metaphors they employ when narrating their adoption story. The use of metaphor in the birthmother narrative was especially important because metaphor …

From Reform To Resignation: Explaining Why Some Protest Movements Escalate Demands, Sooyeon Kang

Electronic Theses and Dissertations

One of the unresolved puzzles in the civil resistance and contentious politics literatures relates to the fact that some movements that begin as reformist (seeking redress in a certain policy space) escalate to maximalist claims (demanding the ouster of a national leader or the entire regime) – a process I call “demand escalation.” For instance, in the summer of 2019, thousands took to the streets of Hong Kong to protest a proposed extradition bill that would allow criminal suspects to be sent to mainland China to face trial in courts controlled by the Communist Party. However, even after Hong Kong’s …

Trainee Attitudes Toward Social Class As Predictors Of Clinical Decision Making: Exploring The Effects Of Classism In Psychotherapy, Jeremy J. Coleman

Electronic Theses and Dissertations

The current study examined the effects of classist beliefs on trainee attitudes toward their client based on perceived social-class status. This study sought to determine whether classist attitudes contribute to meaningful differences in clinical decision making. A sample of mental health trainees (n = 147) attending graduate-level programs in the U.S. were recruited and randomly assigned to one of two clinical vignette conditions. Both vignette conditions included identical data regarding a hypothetical client’s presenting concerns (e.g., sleep disturbance, worry, rumination, loneliness), but differed on indicators of client socioeconomic status (SES). Results showed statistically significant between-group differences on ratings of clinical …

Psychological Factors That Impact White Counseling Trainees’ Responses To Cultural Ruptures, Emma Freetly Porter

Electronic Theses and Dissertations

In the field of counseling and clinical psychology, the last several decades have been characterized by a strengthened recognition of the importance of cultural factors in psychotherapy. While this has been impactful, there is evidence that cultural ruptures, microaggressions, and racial/ethnic disparities in psychotherapy outcomes persist. Aversive racism theory, which provides explanations for the racist tendencies typically associated with progressive White individuals, postulates that a conflict between explicit egalitarian beliefs and implicit negative racial biases impedes White individuals from adequately addressing and acknowledging underlying biases. Therefore, it was hypothesized that psychological factors, such as defense mechanisms, professional selfdoubt and self-compassion, …

The Productivity Wage Gap, Monopsony, And Labor Share Decline: An Analysis Of Wage Suppression Perpetuated By Power, Alexandra Coulter

Electronic Theses and Dissertations

This thesis argues that wage suppression along with the decline in the labor share is caused by a rise in monopsony power realized as a significant increase in the profit share. It attributes the rise in monopsonistic behavior to the development and expansion of the modern corporation. This thesis investigates the reasons for wage suppression, identifies causes of the declining labor share left as exogenous in mainstream models, examines traditional economic wage determination and search models, and evaluates the political economy implications. This work reviews literature on imperfect competition, the corporation, contracts, search and match models, and the motivation of …

The Essence Of Reincarnation And Consciousness As A Gateway Into Teaching And Learning, C. Capucine Chapman

Electronic Theses and Dissertations

This phenomenological study explores the essence of ancestral knowledge from a belief in reincarnation and consciousness, as it relates to the lived experiences of diverse educational professionals, and its contribution to their growth and development. The study investigates the lived experiences of adult educators from four distinct teaching and learning environments: applied metaphysics, Buddhism, anthroposophy, and Indigenous. All participants maintain a practicing belief in reincarnation, consciousness, and ancient and/or esoteric knowledge. The present study sought to understand how this knowledge influenced and impacted educator growth and development, and examined overlaps in teaching and learning.

Electronic Theses and Dissertations

The purpose of the current hermeneutic phenomenological qualitative study was to understand the phenomenon of Muslim Americans’ lived experiences of Islamophobia prior to and two years into Donald Trump’s presidential administration. 14 participants from multiple regions in the United States completed a semi-structured interview via telephone. The data analysis revealed seven major themes: 1) Muslim Americans experience different dimensions of Islamophobia, 2) Muslim Americans experience various forms of Islamophobia, 3) Variables that impact the prevalence of Islamophobia, 4) Islamophobia impacts various areas of Muslim Americans’ lives, 5) Muslim Americans may react differently to experiences of Islamophobia, 6) Islamophobia impacts the …

Maternal Hpa Axis Function During Parenting Is Associated With Reduced Brain Activation To Infant Cry And More Intrusive Parenting Behavior, Andrew Erhart

Electronic Theses and Dissertations

Previous research indicated that maternal cortisol function and maternal brain response to infant stimuli are separately related to differences in parenting behavior. Evidence from animal models have demonstrated that chronically high cortisol concentration alters brain structure and function, suggesting that studying these two mechanisms together may further improve understanding of parental behavior in human mothers. First time mothers of infants aged 1-7 months old (M age = 3 months) were recruited to participate. Mother’s cortisol concentration was measured during a naturalistic interaction with their infant and their behavior was coded for maternal sensitivity and nonintrusiveness. In a separate session using …

Child Abuse And Revictimization: Improving Models Of Revictimization Risk, Julie M. Olomi

Electronic Theses and Dissertations

Child abuse (CA) puts women at risk for later victimization by a different perpetrator, referred to as revictimization (RV); however, how this risk is conveyed is not well understood. CA is associated with a diverse set of negative sequelae (e.g., posttraumatic symptomology, emotion regulation difficulties), many of which could plausibly affect risk for RV. To date, most empirical studies of RV have mainly compared groups of women with and without abuse and RV histories using variablecentered approaches. This approach has led to a focus on differences between abused and non-abused women on a few CA-related variables tested at a time. …

Fatty Fatty Two-By-Four—Can’T Get Through The Dressing Room Door?: An Examination Of Excess As Queer Failure, Miranda Dottie Olzman

Electronic Theses and Dissertations

Failure and fat are not linear. It is taught, learned, reminded, and internalized. Our bodies have memories that are built through repeated moments. And for me, failure has been a part of my body’s map since I was born. This project is the culmination of many failures. In this dissertation, I am examining queer failure in multiple contexts including body size, as well as religion to create a corpulent critique. I do this by examining the lineage of queer failure as well as queer temporality as it is linked to failure (Edelman; Muñoz; Halberstam; Love) with fat queer bodies serving …

U.S. International Trade And National Security In The Trump Era: Mercantilism, Liberalism, Or Economic Nationalism?, Brett D. Barkey

Electronic Theses and Dissertations

This study will explore the Trump administration’s views of national security as expressed through its international trade policy and ask whether the U.S. is now a mercantilist, a liberal, or an economically nationalist nation. This study will define mercantilism, liberalism and economic nationalism turning for assistance to the writings of Alexander Hamilton, Adam Smith, and Friedrich List.

The study will then explore how those concepts may have been revealed in America’s international trade policy as the U.S. navigated the economic and national security events of the 20th century, and on to 2016 as President-elect Trump prepared to take office. Next …

Because I Said So: The (Re)Production Of White, Ableist Narratives Through Legal Discourse In Endrew F. V. Douglas County Re-1, Stephen F. Fusco

Electronic Theses and Dissertations

As families and advocates of students of color labeled with dis/abilities face mounting inequities they turn to the courts seeking protection. Unfortunately, even after courts issue written decisions ostensibly designed to protect students labeled dis/abled, these students continue to experience systematic oppression in school. This is due, in part, to the discourse used by the courts when addressing issues affecting students labeled dis/abled and the elitism of the judicial system. The purpose of this study was to examine the legal discourse used in the most recent Supreme Court case concerning the education of students labeled dis/abled, Endrew F. v. Douglas …

Preconception Stress, Affect-Biased Attention, And Negative Affectivity: Assessing Pathways And Early Markers Of Psychopathological Risk In Infancy And Childhood, Danielle A. Swales

Electronic Theses and Dissertations

The developmental origins of mental health likely begin early in life and perhaps even prior to conception. Research is needed to elucidate pathways of risk and resilience in the development of psychopathology. The goal of the current dissertation was to explore how both preconception and postnatal experiences influence negative affectivity, a robust and transdiagnostic risk factor for later psychiatric symptoms. The present dissertation accomplished this goal by completing two independent studies, each of which are presented in the format of standalone journal articles. Study one focused on evaluating how preconception experiences, specifically maternal symptoms of post-traumatic stress disorder (PTSD), impact …

Mechanisms Of Sensory Adaptation In The Primate Visual System, Boris Isaac Peñaloza Rojas

Electronic Theses and Dissertations

Under ecological conditions, the luminance impinging on the retina varies within a dynamic range of 220 dB. Stimulus contrast can also vary drastically within a scene, and eye movements leave little time for sampling luminance. In addition, the amount of information reaching our visual system far exceeds the brain’s information processing capacity. Given the limited dynamic range of its neurons and its limited capacity in processing visual information in real-time, the brain deploys both structural and functional solutions that work in tandem to adapt to the surroundings. In this work, employing visual psychophysics and computational neuroscience, we study the mechanisms …

Lawthy: Holding Flowers, Bailey Pittenger

Electronic Theses and Dissertations

The research and design of this dissertation involves four parts: 1) Bridges to Care Work in the Sick Room, an essay that begins bridges across care genealogies, foundational literature on nursing and sick rooms, and applications of care work and care logic via local protest, civic, and community engagements; 2) “Writing Lawthy,” which is a process-based approach to literary and social sciences research on “writing on memory loss” and dementia narratives that center personhood and autonomy; 3) Lawthy: Holding Flowers, a fragmented novel created by first-hand accounts of caregiving, a 1981 journal, and fiction; and 4) appendices of local city …

Spiritual Care Of Gay Men In Committed Relationships: An Evidenced-Based Intercultural Approach, Marc J. Coulter

Electronic Theses and Dissertations

Sexual minorities have historically been targets of homophobia, heterosexism, discrimination, and persecution particularly within traditional, conservative religious organizations. As a result, many people who identify as male and gay reject traditional forms of religion and seek alternative spiritual beliefs and practices affirming their sexual orientation, often self-identifying as “spiritual but not religious” (SBNR). Some white, gay male couples in committed relationships also reject traditional views of sexual fidelity and negotiate open, consensual, non-monogamous sexual relationships with their primary partner. Gay couples seeking behavioral health assistance to navigate relational difficulties may encounter clinicians who fail to acknowledge the harmful influence of …

Characterization Of The Whale Shark (Rhincodon Typus) Melanocortin-2 Receptor, Brianne Hoglin

Electronic Theses and Dissertations

Among bony vertebrates, the melanocortin-2 receptor ortholog is unique among the family of five melanocortin receptors on the basis that it is dependent on its accessory protein, MRAP1, for trafficking and activation, and is selective for activation by ACTH alone. Previous studies on the MC2R orthologs of select cartilaginous fish, the elephant shark (Callorhinchus milii) and the red stingray (Dasyatis akajei), revealed divergent traits in a less obligatory relationship on MRAP1 and its ability to be activated by ACTH or the MSH-sized peptides. However, observed traits were not consistent between these two cartilaginous fish species, posing …

Testing A Sociocultural Model Of Body Image In Women Athletes With Disabilities, Brooke R. Lamphere

Electronic Theses and Dissertations

Evidence suggests that athletes and people with disabilities (PWD) experience multiple body images that change relative to their social context (e.g., Petrie & Greenleaf, 2012). The powerful influence of social factors on body image and disordered eating in women athletes is well-documented (e.g., Schaefer, et al., 2015; Fitzsimmons-Craft et al., 2014), as is the centrality of the body in the lived experience of athletes and PWD (Behel & Rybarczyk, 2012; Galli et al., 2016); yet, limited research has explored the effects of social factors on body image in athletes with disabilities (i.e., AWD; e.g., Galli et al., 2016; Sousa et …

Statistical Modeling Of Positive Peer Support On Longitudinal Adolescent Substance Use, Kady Rost

Electronic Theses and Dissertations

To evaluate this study’s research question of ”Does the latent construct of Positive Peer Support (PPS) relate to the construct of Adolescent Substance Use (ASU) over time, controlling for neighborhood safety, race, and sex?”, Structural Equation (SEM) and Latent Growth Curve Modeling (LGCM) were used to investigate trajectories. Secondary longitudinal data from Zimmerman (2014) of 604 students enrolled for four consecutive years in public schools located in Flint, Michigan. In the secondary data resource, students who participated were declared “at risk” by GPA. Significant relationships were found in SEM: Positive Peer Support to Adolescent Substance Use, All Control Variables to …

The Combined Impact Of Continuous And Ordinal Auxiliary Variables On Missing Data Imputation In Sem, Salina Wu Whitaker

Electronic Theses and Dissertations

“Modern” methods of addressing missing data using full-information maximum-likelihood (FIML) have become mainstays in SEM analyses. FIML allows the inclusion of auxiliary variables which carry information that is related to missing values and can reduce bias in parameter estimates. Past research has illustrated the benefits of auxiliary variable inclusion under different missingness conditions (MCAR and MNAR; e.g., Enders, 2008), missingness proportions (e.g., Collins et al., 2001), and although limited, missingness patterns (e.g., Yoo, 2009) in FIML analyses. While past studies have focused on the effects of either continuous or ordinal auxiliary variables, no study has included both types in their …
