Public-Private Partnerships (Ppp) In Technical Education: The Case Of Egypt’S Applied Technology Schools (Ats), Youstina Magdy

Theses and Dissertations

Technical education is a form of education that gained momentum in the 1800s and was considered as a parallel distinct model to general education by the post-war period. Public-private partnerships (PPPs) were one of the scaling up and enhancement efforts of technical education. In Egypt, the technical secondary education system has various school models; however, it was until 2018, when we first see the implementation of an PPP model with the establishment of the Applied Technology Schools (ATS). ATS schools aim at supplying the labor market with experienced skillful competent graduates in the demanded sectors in the Egyptian labor market, …

What's Your Type? The Relationship Between Enneagram Personality Style And Psychiatric Diagnosis, Danielle Augusta Huber

Theses and Dissertations

Despite its long history and ever-growing popularity amongst mental health providers and laypeople, the Enneagram model of personality has seen limited empirical support regarding its clinical relevance and efficacy. The present study sought to contribute to the literature supporting the Enneagram’s use in psychotherapy. As a majority of therapeutic services aim for the reduction and/or resolution of psychopathology, often in terms of one or more diagnoses, and as previous research has theorized how the Enneagram model and psychiatric diagnoses might be related (Palmer, 1988), it was the researchers’ intention to analyze whether these theoretical associations could be statistically supported. This …

An Examination Of Mmpi-3 Score Patterns Of Sex-Trafficked Women, Edleen De Jesus-Sanchez

Theses and Dissertations

Sex trafficking is a hidden crime that affects many vulnerable groups such as women and children. Prior research has demonstrated that individuals currently or formerly engaged in sex trafficking experience heightened levels of depression, anxiety, posttraumatic stress disorder (PTSD), and other mental health concerns. Most of these studies relied on structured interviews and, to date, no empirical studies have evaluated the psychological difficulties of sex trafficking victims with an empirically valid measure. The Minnesota Multiphasic Personality Inventory-3 (MMPI-3; Ben-Porath & Tellegen, 2020a) is a personality assessment measure widely used to assess sexual abuse survivors, substance abusers, and various inpatient and …

Application Of Computational Tools To Identify Variations Associated With Peromyscus Dominant Spot, Zhenhua Shang

The Intersectionality Of Rurality And Race On Covid-19 Vaccination Among Adults In The United States, Shiba Simon Bailey

Theses and Dissertations

Background Vaccination remains a cornerstone of public health, significantly contributing to the prevention and control of infectious diseases. During the COVID-19 pandemic, vaccine development was critical to prevent new SARS-Cov-2 infections. However, COVID-19 vaccination uptake among racial and ethnic minority populations and rural residents in the United States (US) lags behind their urban non-Hispanic White counterparts. Underlying causes of these disparities are unclear, but vaccine hesitancy, access to care barriers, and structural racism may be to blame. Such barriers may vary by residential urbanicity, leading to different racial/ethnic disparities in rural and urban America. Understanding the variations in vaccine uptake …

Revolting Motherhood: [De]Generative Breast Stories Transmuting Medical/Moral Paradigms In Britain During The Long Nineteenth Century, Leslie Rene Pearson

Theses and Dissertations

Eric Plemons writes in *The Look of A Woman* that “biological stories do more than describe biologies” (54). This dissertation explores what breast cancer stories do and how society creates meaning around the experience of breast cancer. I argue that, in the long nineteenth century in Britain, breast cancer was part of a two-sided medical/moral paradigm where medical diagnosis became enmeshed with morality. Health, then, became a result of proper domestic behavior, disease a result of straying from societal norms. Following the introductory chapter, chapter two traces the development of this paradigm as an outgrowth of the emergence of middle-class …

Adverse Childhood Experiences And Social Determinants Of Health In Relation To Cigarette Smoking And E-Cigarette Use Among Adults, Kankana Sengupta

Theses and Dissertations

Cigarette smoking is the leading cause of preventable morbidity and premature mortality in the U.S. and other high-income nations. E-cigarette use or vaping is an addictive behavior. During the past 5 years, the prevalence of e-cigarette use has increased markedly in U.S. adolescents and young adults. The public health implications of this increased prevalence are unclear. Adverse childhood experiences (ACEs) are associated with cigarette smoking in adulthood. However, the pathway from experiencing ACEs in childhood to smoking cigarettes or using e-cigarettes in adulthood is not clearly understood. Additional factors experienced between childhood and adulthood might either increase or decrease the …

The Role Of Insulin Signaling In Controlling Oogenesis In Drosophila Melanogaster, Tancia W. Bradshaw

Theses and Dissertations

Adult stem cell activity responds to organismal nutrient status to maintain and support tissue homeostasis. Despite the intricate relationship between dietary input, adipose tissue and peripheral organ function, we are at the tip of the iceberg regarding our understanding of the cellular and molecular mechanisms underlying adipose communication to other tissues. The Drosophila ovary receives nutritional signals from the fat body with multiple nutrient-sensing pathways functioning in adipocytes to control distinct stages of oogenesis. Insulin/insulin-like growth factor signaling (IIS) within adult adipocytes remotely controls oocyte production at distinct stages of oogenesis. The PI3K/Akt1 axis in adipocytes promotes germline stem cell …

Neural Correlates Of Audiovisual Integration, Jonathan Conrady

Theses and Dissertations

Successfully integrating multiple streams of information is paired with a variety of behavioral enhancements. Multisensory research over the past few decades has demonstrated the criticality of spatial proximity and stimulus effectiveness. Here, we focused on the temporal aspects and underlying neural activity of frequency-varying, audiovisual stimuli using scalp recorded electroencephalography (EEG). Our set of stimuli was particularly chosen because humans are most sensitive to the auditory sound and visual spatial frequencies that make up speech. Recent work has shown that audiovisual integration effects of low-level, simple stimuli are largest when both modalities fall within, compared to outside of, their respective …

The Integration Of Simulation-Enhanced Interprofessional Education Into Undergraduate Clinical Laboratory Science Curriculum, Dana Powell Baker

Theses and Dissertations

This action research study aimed to integrate simulation-enhanced interprofessional education (Sim-IPE) into the undergraduate clinical laboratory science (CLS) program curriculum. The undergraduate CLS curriculum was comprised of didactic coursework and hands-on learning experiences in the student laboratory. This traditional CLS curriculum model was uniprofessional in its design and educated students in silos rather than on interprofessional teams with other health professions students. Lack of collaboration on healthcare teams has led to increased medical errors and decreased patient safety in clinical settings. Recent studies have indicated that effective communication and teamwork among healthcare professionals has led to improved patient outcomes and …

Social Network Attributes Associated With Conversations About Smoking And Cessation And Differences By Socioeconomic Status, Victoria Catherine Lambert

Theses and Dissertations

Conversations about smoking and cessation in response to cessation messages appear to encourage quit attempts, yet there is some evidence that smokers with lower income and education have these conversations less often than their counterparts with higher income and education. No research has investigated the social network characteristics that encourage smokers to have these conversations or the mechanisms for SES differences in these conversations. Because social factors play a role in SES disparities in smoking and cessation as well as other health behaviors and outcomes, social network characteristics likely explain some SES differences in conversations about smoking and cessation. The …

Racial Orientations: A Phenomenological Approach, Nicholas Mazur

Theses and Dissertations

Given the orienting complexities of how race is developed, experienced, performed, and understood, the author argues that a phenomenological approach to uncovering what makes a racial orientation might provide a better understanding of the role of consciousness, the body, and history in race relations. Incorporating knowledges of critical race theory (CRT) and critical whiteness studies (CWS), the author aims to pivot sociological discussions about race into the phenomenological field where racial orientations can be understood from another dimension. Specifically, the author offers as an additional theoretical framework in the form of a phenomenological methodology for pedagogies addressing race and issues …

The Association Between Symptoms Of Adhd And Alcohol Use And Related Consequences In College Students: Social And Environmental Protective And Risk Factors As Moderators Of This Relation, Cameron Shepard Massey

Theses and Dissertations

Alcohol use, while common in college student populations, can bring about significant mental health and educational problems that have negative consequences (Harris et al., 2017; White & Hingson, 2013). Attention-deficit/hyperactivity disorder (ADHD) can also result in significant impairment in academic settings (Kuriyan et al., 2012; Blase et al., 2009, Barbaresi et al., 2007), and those with ADHD often show increased rates of alcohol consumption and related problems, which can greatly increase the risk for students to struggle in college (Barbaresi et al., 2013; Baker et al., 2012). Examining the impact that specific risk and protective factors play in this relation …
