A Text-Message Nudge Intervention To Increase Student Professional Development Education, Catherine Voss Plaxton

Dissertations

This experimental study explored the effects of a text-message intervention on college sophomore and junior engagement in professional development at San José State University. One goal of the study was to assess whether status quo bias poses a barrier to student preparation for the college-to-work transition. A second goal was to measure the impact of a text-message, behavioral design intervention intended to influence real-time decision-making and overcome status quo bias toward professional development. The treatment intervention had a weak positive, but not significant, effect on student engagement in professional development. Alternative explanations were sought for post-intervention differences in professional development …

Tracing Sehnsucht To Place: Mythopoeia, Visions, Transcendence, And The Journey Of The Rhetorical Refugee, G. Brandon Knight

Dissertations

This dissertation seeks to explicate a rhetorical conceptualization from C. S. Lewis’s notion of longing, or sehnsucht, in hopes of extending its employment to two other contemporary contexts—Christian Hedonism and American Humanism. To do so, I utilize the method of rhetorical criticism to analyze Lewis’s most famous sermon entitled The Weight of Glory. Following this paradigm chapter, I then compare uses of longing within the contemporary evangelical philosophy called Christian Hedonism initiated during the eighties through the seminal text entitled Desiring God: Meditations of a Christian Hedonist. In doing so, I uncover distinct aspects of longing within …

The Role Of Plasmids And Clones In The Emergence Of Carbapenem Resistant Enterobacteriaceae In The United Arab Emirates, Shaimaa Fekry Mahmoud Mouftah Ali

Dissertations

Resistance to carbapenems, the ultimate beta-lactam antibiotics used to treat life-threatening Gram-negative infections associates with very high mortality. Consequently, carbapenem-resistant Enterobacteriaceae (CRE), which are usually multi- or extremely drug-resistant, is considered a critical pathogen. To help to control their spread, we investigated the molecular epidemiology of CRE in the United Arab Emirates (UAE) and its neighboring countries. CRE isolated in the UAE were screened for IncX3 incompatibility type plasmids carrying carbapenemases. The complete sequence of the IncX3 plasmids identified was established. Thirty CRE carried blaNDM-1, blaNDM-4, blaNDM-5, blaNDM-7, blaOXA-181, and blaKPC-2 on IncX3 plasmids. …

However, virtual teams face many challenges resulting from a lack of face-to-face contact. Based on existing relevant literature, this study contributes a unique insight into how some challenges surrounding virtual team performance might be addressed. …

Development And Validation Of New Models And Metrics For The Assessments Of Noise-Induced Hearing Loss, Wisam Subhi Talib Al-Dayyeni

Dissertations

Noise-induced hearing loss (NIHL) is one of the most common illnesses that is frequently reported in the occupational and military sectors. Hearing loss due to high noise exposure is a major health problem with economic consequences. Industrial and military noise exposures often contain high-level impulsive noise components. The presence of these impulsive noise components complicates the assessment of noise levels for hearing conservation purposes. The current noise guidelines use equal energy hypothesis (EEH) based metrics to evaluate the risk of hearing loss. A number of studies show that the current noise metrics often underestimates the risk of hearing loss in …

Necessary And Sufficient: Examining The Role Of Attachment Trauma And Psychological Maltreatment As Primary Etiological Factors In The Development Of Borderline Personality Disorder, Chacy Agnello

Dissertations

Current widely-accepted conceptualizations regarding borderline personality disorder (BPD) profess that trauma is not required in the etiology of BPD and place a significant focus on biological predispositions. This review sought to evaluate the current paradigms regarding BPD and examine whether trauma may be the most significant contributing factor in the development of BPD. Studies on developmental trauma (including psychological maltreatment) and attachment were examined. These studies appear to strongly support the idea that when disrupted attachment and psychological maltreatment are taken into consideration, trauma does appear to be both necessary and sufficient as primary etiological factors in the development of …

Education And The Art Viewing Experience: The Evolution Of Learning In Museums And Corporate Art Collections, Piper Hutson

Dissertations

By investigating the history of corporate art collections and the evolution of educational frameworks in museums, this case study questions the differences between exhibition formats to illuminate possible areas of improvement. Museums were initially formed to display collections donated by wealthy or royal families and constructed around the ‘Curator’s Gallery’ format. This exhibition type focused on the aesthetic arrangement of objects based on the established art historical canon hierarchy and were accompanied by minimal ‘tombstone’ labels with little, if any, didactic information. Science museums emerged in the middle of the 19th century and were among the first informal learning institutions …

A Mixed Methods Study Comparing Nursing Preceptored Clinical Learning Experiences And Nursing Simulation Clinical Learning Experiences Of Nursing Students In A Midwest Community College, Teresa R. Hamra

Dissertations

Among schools of nursing nationwide, the competition for clinical sites, and insufficient numbers of nurse preceptors led nursing schools to turn away thousands of qualified applicants. Due to a shortage of clinical sites, shortage of nurse preceptors, and an increase in simulation technology, nursing schools used simulation clinical in place of traditional clinical experiences. Much of the literature supported using simulation as a replacement for traditional clinical hours. The literature discussed a gap in transition to practice from student nurse to professional nurse and pointed to safety issues as the highest concern in practice settings. One Midwest community college faced …

You Look Like Me: The Impact Of Demographic Similarity On Picture Primes’ Effectiveness, Jennifer L. Unnerstall

Dissertations

Past research has clearly demonstrated the ability of various primes to influence behavior; however, little is understood about how and why primes work. The present research takes a theory-based approach to begin to understand this further. First, it investigates whether a picture prime has the ability to influence cooperative and competitive concept activation and implicit associations. Then, it examines whether the characteristics of the picture prime, specifically the race of the individuals depicted in the prime and whether it matches the race of the participant (i.e., demographic similarity), moderate these effects. Secondly, the present research investigates whether the same picture …

Experiences Of Caregivers Of Dementia Patients With An Integrated Primary Care Model, Mariya Alekseyevna Kovaleva

Dissertations

Few U.S. dementia care programs are led by advanced practice registered nurses (APRNs), including a dementia patient-centered medical home, the Integrated Memory Care Clinic (IMCC) at Emory Healthcare. To our best knowledge, the IMCC is the only U.S. dementia care program where primary care and dementia care are provided simultaneously. This study aimed to explore the experiences of caregivers of persons living with dementia (PLWD) and PLWD (as reported by their caregivers) at the IMCC. This prospective longitudinal cohort study employed quantitative and qualitative methods. The study began with a scoping review of the U.S. dementia care programs. Caregivers participated …

By “generative,” we mean to highlight methods that focus on helping learners of all kinds develop creativity and take ownership over their learning, approaches that will help them build agency and grow skills simultaneously. Here, we explore …

“I Am Whatever You Say I Am”: The Social Construction Of Identity In Rural Drug-Using Women’S Narratives, Amanda Bolton

Dissertations

Previous narrative criminology research has examined how drug users manage their identities through discussions of themselves, while providing little insight into how they manage their identities through discussions of others(McIntosh & McKeganey, 2000; Rødner, 2005; Sandberg, 2009).It is important to consider others because according to many symbolic interactionists (Cooley, 1902; Goffman, 1959; Mead, 1934), identity is a social product that is constructed and maintained through social interaction with others and is based on perceptions of others. Cooley (1902) more specifically argued that one’s primary group (i.e., those that are relationally or proximally close to an individual) are even …

Peroxisomal Protein Defects Disrupt Coordinated Peroxisomal Processes And Affect Early Seedling Development Through Accumulating Toxic Catabolic Intermediates, Ying Li

Dissertations

Many peroxisomal proteins act in β-oxidation processes on a range of substrates. It is unclear how these proteins are coordinated to determine the flux of peroxisomal processes and meet the requirements for plant growth and development. Using mutant analysis and metabolic profiling, I examined proteins predicted to act in fatty acid and indole-butyric-acid (IBA) β-oxidation. ECH2 confers enoyl-CoA hydratase activity for the auxiliary β-oxidation of fatty acids with an even cis-unsaturated bond. ECH2 was suggested to function in IBA β-oxidation, as ech2 seedlings have altered IBA response. ech2 seedlings have reduced root length and cotyledon area. ech2 seedlings accumulate 3-hydroxyoctenoate …

An Examination Of Disingenuous Deeds By St. Louis Public Schools 1945-1983, Michael Brown

Dissertations

The Saint Louis Public Schools (SLPS) St. Louis, Missouri, operated a de facto segregated school system for three decades after the United States Supreme Court decision Brown v. Board of Education. National and local media outlets celebrated St. Louis Public Schools for their desegregation plan in response to the 1954 United States Supreme Court Brown v. Board of Education decision. However, the counter narrative to media celebration is that the St. Louis Public Schools system practiced de facto segregation. In reality the St. Louis school district officials protected school segregation for half a century. In this research, I will …

Understanding Comorbid Depression In The Context Of Ptsd Through Underlying Dimensions, Melissa Turkel

Dissertations

Depression co-occurs with Posttraumatic Stress Disorder at a high rate, resulting in numerous complications for pathology and treatment. More research is needed regarding variables that may explain this common comorbidity. One possible variable is that of underlying dimensions, latent factors that give rise to these manifestations of psychopathology. This study explored potential underlying mechanisms of comorbid PTSD and depression, including negative affect, rumination, emotion dysregulation, neuroticism, and behavioral inhibition. While previous studies have investigated these dimensions individually, there is a dearth of research that simultaneously investigates multiple dimensions or determines the relative contributions of underlying dimensions to psychopathology. Thus, the …

Career Technical Education prepares students for the workforce. Creating an academic learning platform that mimics technical instruction where students solve real life problems can encourage students to …

Loss Of A Sibling: A Phenomenological Exploration Of The Experiences Of School-Aged Children, Barbara Dixon

Dissertations

More than 50,000 child mortalities are recorded in the U.S. each year. As a result, almost 8% of the population experience the loss of a brother or sister before age 25 (Jacobs & Bovasso, 2000). This study was an open conversational exchange with ten Grief Counselors who worked with school-aged children, who had experienced the loss of a sibling, to identify the behaviors and expressions of this group of Disenfranchised Grievers. Three patterns were identified: 1) Grief in children takes different forms, 2) Sibling loss in childhood is a life-changing event and 3) Childhood grief has its own time. Each …
