You're Kind Of Just Conditioned: Women And Female College Students' Defiance Of Dominant Social Messages In The Development Of Leader Self-Efficacy, Shannon Darracott Howes

Dissertations

Researchers have consistently found that women have lower leader self-efficacy (LSE) than men, despite being equally capable as leaders. This is problematic because LSE is associated with many benefits that support the development and enactment of leadership. Despite the importance of LSE, there is a dearth of research on the construct, particularly in the higher education context. This grounded theory study utilized semi-structured interviews with 12 undergraduate students who identified as females or women to explore how they developed LSE. Findings were related with four core concepts that were woven throughout the various categories of themes that comprised the grounded …

Cognitive And Neural Correlates Of Coping And Resilience In Depression, Catherine Lee

Dissertations

Depression is one of the most prevalent and devastating psychological disorders, often with a chronic or remitting/reoccurring course. The inability to effectively cope with stress and negative life events has been strongly linked to the development and maintenance of depression symptoms; yet, the cognitive and biological processes underlying the complex and multidimensional behavioral construct of coping are not well understood. Using a combination of self-report measures, computerized cognitive tasks, and scalp electroencephalography (EEG) methodologies, the present study investigated associations between specific executive function abilities (i.e., inhibition and set-shifting), underlying neural activity, coping strategy and flexibility, and depression symptoms. Results did …

Community Violence Exposure Among Urban African American Males: Understanding The “Buffering Effect” Of Adaptive Social Support Coping On Psychosocial Outcomes, Cynthia L. Pierre

Dissertations

The current study explored the moderating roles of support coping and support

quality in the predictive relationship between community violence exposure (ECV) and a

variety of psychosocial outcomes. Participants were 119 African American males (9 th –

12 th grade; mean age at baseline = 15.33). Participants completed measures of exposure to

violence, support-seeking coping, quality of support from friends and family, and a range

of psychosocial outcomes, and completed these same measures approximately one year

after baseline. Regression analyses were conducted to examine the relationships between

ECV and psychosocial outcomes, as well as the relationships between support coping and …

Changing Medical Education: Early Efforts To Integrate Women's Health Into Education And Training, Mary Katherine Rojek

Dissertations

This is an historical study about the development of women’s health curricula in medical education across the U.S. between 1983 and 2004, a period of a great deal of innovation. At that time, some physicians, medical educators, policy makers, and government officials became aware that most U.S. medical school curricula did not address women’s health in a comprehensive manner and did not attend to many problems that were the primary causes of mortality and morbidity in women. In addition, medical research and medical education were based on a normative male model. Studies of medical education indicate that medical schools are …

“I Am Because We Are”: A Portrait Of Trans* Postsecondary Educators’ Experiences In Higher Education, Symone L. Simmons

Dissertations

Within higher education, trans* students have become more visible and advocacy for them important. To support these claims, scholars have conducted research and produced literature on trans* college students’ identity development and experiences on campuses. However, the lived experiences of trans* educators working in colleges and universities are missing from the literature, consequently from the minds of scholars, practitioners, and administrators alike. Trans* educators experiences are important because they contribute to shifts in higher education conversations around supporting and affirming trans* people on campus. Trans* educators are mentors, advisors, and role-models, teachers, and advocates, and perhaps knowing their journey and …

The Relation Of Exposure To Community Violence To Self- Efficacy Based On Neighborhood, Family, And School Effects In A Community Sample Of Latino-American Youth, Arie Zakaryan

Dissertations

Community violence is considered a “public health epidemic” in the US. Latino youth and families are a burgeoning population in the United States, and many of whom live in neighborhoods exposed to community violence. Multiple contexts should be assessed identifying developmental assets youth use to adjust positively when exposed to violence. This study examines how different environmental contexts, i.e., home, school, neighborhood and acculturation, influence the relationship between exposure to community violence and self-efficacy for Latino youth. The current study uses an archival dataset of a larger longitudinal study (Project on Human Development in Chicago Neighborhoods). A confirmatory factor analysis …

The Impact Of Social Class Connectedness, School Belongingness, And Family Cohesion On Lower Class-Identified College Students, Kristen Eileen Adams

Dissertations

This study is one of the first to examine acculturative and enculturative factors as they relate to social class. Much of the extant literature surrounding acculturation and enculturation looks primarily at cultural factors such as race/ethnicity and/or immigration status. Due to the fact that social class is such a salient cultural identity in most individuals' lives and has a bearing on how one views and evaluates themselves in relation to others of differing social classes (Fouad & Brown, 2000), the purpose of this study was to examine the effects of social class connectedness on subjective wellbeing (including positive and negative …

Self-Esteem And Critical Consciousness In The Relation Between Subjective Social Class And Subjective Well-Being Among College Students: Mediation And Moderated Mediation Models, Fatma Aydin

Dissertations

Subjective social class (SSC) and subjective well-being (SWB) are important indicators of mental health, and the scientific literature has indicated significant relationships between these variables. The purpose of this study is to examine the complex mechanisms by which SSC is related to SWB, using a sample of 275 college students. This study first explored whether SSC was indirectly related to SWB through the mediating effect of self-esteem. Three elements of SSC (economic resources, social power, and social prestige) and three elements of SWB (satisfaction with life, negative affect, and positive affect) were investigated. Using process analysis, the results showed that …

Critical Role Of C-Jun N-Terminal Kinase Signaling In Binge Alcohol-Driven Atrial Arrhythmic Remodeling, Jiajie Yan Yan

Dissertations

Holiday Heart Syndrome (HHS) is cardiac arrhythmia induced by binge alcohol consumption, a drinking pattern affects 38 million adults in our society. Atrial fibrillation (AF) is the most frequently diagnosed arrhythmia in HHS and causes significant morbidity and mortality. Despite the intensive prevention effort nationwide, the binge drinking population keeps rising. However, no effective treatment strategies are available for binge drinking induced AF due to the unknown underlying mechanisms. In this thesis, I aim to elucidate the mechanisms of binge alcohol-promoted atrial arrhythmogenicity by using a mouse model of repeated binge alcohol exposure established in the Ai Lab.

Latina Principals In Southern California: A Phenomenological Look Into Their Journey Towards Leadership, Fabiola Bagula

Dissertations

California is home to almost 15 million Latinos, however, according to the 2015 State of Higher Education Report for California, only 12% of the Latino population between the ages of 25 and 64 has a baccalaureate degree or higher, compared with 42% of the White population. Latina students have some of the lowest levels of educational attainment at every point in their K-12 journey and in general, very low occupational attainment. Given these troubling findings, this research sought to understand and tell the stories of Latinas in k-12 leadership positions in Southern California. In this study, Latinas describe how they …

Campus Mental Health Practices And The Stigma Of Mental Illness: A Quantitative Analysis Of Student Affairs Professionals, Megan Krone

Dissertations

Around half of undergraduate college students will experience mental illness to some extent during their academic careers, yet a low percentage of students experiencing signs and symptoms of mental illness will seek help despite the availability of proven, effective treatments. The field of higher education has demonstrated a genuine concern for individuals with mental illnesses and mental health care on campuses, yet implementation of practices that connect students to treatment is inconsistent and effectiveness is uncertain.

This study searched for associations between campus practices and campus culture regarding mental illness. While institutions of higher education are using both traditional and …

The Multiple Meanings Of San Diego's Little Italy: A Study Of The Impact Of Real And Symbolic Space And Boundaries On The Ethnic Identities Of Eight Italian Americans, Thomas Joseph Cesarini

Dissertations

The literature suggests that identifying with a particular place can promote a sense of ethnic identity. This study focused on eight Italian American community members’ perceptions of San Diego’s Little Italy as both a container and creator of ethnic identity. The study addressed a) how the participants define and convey their Italian American ethnic identity and b) how the participants perceive the role of San Diego’s Little Italy pre-redevelopment and post-redevelopment in creating and shaping their sense of being Italian American.

The study employed a case-study design. Ethnohistoric accounts of life experiences were gathered from participants selected through convenience and …

A Mixed Methods Exploration Of Minority Resource Eligibility For Half White Multiracial College Students, Nicholas Reyes Franco

Dissertations

Over the last several decades, multiracial populations have received increased attention in academic literature, particularly regarding identity development and psychological health and wellness. Less attention has been given to individuals with one minority and one white parent (i.e., half white individuals) in the context of affirmative action and higher education. Existing quantitative studies on this topic suggest, on the one hand, that half white individuals are likely to be considered members of racial minorities, yet, on the other hand, less of a minority—and less deserving of affirmative action benefits—than monoracial individuals or multiracial individuals with multiple minority identities. College students’ …

Symptom Experience And Influenza-Like Illness In A Military Population, Monique Bouvier

Dissertations

AIMS: The primary objective of this study was to identify if symptom presentation expressed over the course of an influenza-like illness (ILI) can predict virus type by use of unsupervised machine learning. The secondary objective was to describe clinical characteristics of strain specific coronavirus. Finally, examine the psychometric properties of the Canadian Acute Respiratory Illness and Flu Scale (CARIFS).

BACKGROUND: ILI outbreaks have been a significant source of non-battle injury among military personnel. Many different viruses cause ILI, and it is difficult to determine which virus is causing the illness. Recent studies have examined the etiology and epidemiology of ILIs. …

An Exploration Of The Use Of Photovoice-Inspired Techniques To Facilitate Narrative Leadership In A Small Group Of Middle-Aged Women, Michelle M. Zive

Dissertations

Leadership often is defined as a persuasive relationship. Over the last two decades, narrative leadership has been viewed in the Leadership Studies literature as a source of persuasion. Narrative leaders use stories to impact others in both large-scale political and social movements, as well as in large-scale organizations. Even as this has been happening, the field also has begun to re-conceptualize leadership as a group rather than an individual process, a view of leadership sometimes characterized as shared leadership. There is limited understanding of whether narrative leadership operates in shared leadership situations and a dearth of literature about specific techniques …

Evolutionary Dynamics Of Speciation And Extinction, Dawn Michelle King

Dissertations

Presented here is an interdisciplinary study that draws connections between the fields of physics, mathematics, and evolutionary biology. Importantly, as we move through the Anthropocene Epoch, where human-driven climate change threatens biodiversity, understanding how an evolving population responds to extinction stress could be key to saving endangered ecosystems. With a neutral, agent-based model that incorporates the main principles of Darwinian evolution, such as heritability, variability, and competition, the dynamics of speciation and extinction is investigated. The simulated organisms evolve according to the reaction-diffusion rules of the 2D directed percolation universality class. Offspring are generated according to one of three reproduction …

Transformational Learning: An Investigation Of The Emotional Maturation Advancement In Learners Aged 50 And Older, Susan Lorraine Lundry

Dissertations

Human beings have spent much time and effort in trying to understand themselves, others, and their world. Mankind uses intellect when trying to understand life but the majority of people continue to encounter frustration, confusion, and a variety of obstacles when dealing with daily challenges and people. Theorists and researchers understand that successful existence requires more than mere knowledge; it requires a level of understanding, a form of wisdom foreign to the bulk of the populace. The missing ingredient for this kind of wisdom is the ability to ‘know thyself,’ which is the beginning of establishing a higher level of …

Dissertations

This study explored the perspectives of students participating in the Voluntary Inter-district Choice program from 2000-2004 and the experiences of participants in the Student Transfer Program attending the same suburban district due to the lack of accreditation in their neighboring schools during 2013-2014. The study uncovered the voices of participants in the VICC and student transfer program and to provided their voices in hope that it may be used as an instrument of change. This subjective, phenomenological qualitative study explored the lived experiences of high school students transferring to suburban districts and provides an in-depth analysis of their social, emotional, …

Women, Sex, And God: Women's Sexuality And The Internalization Of Religious Messages, Petra Sterling Blum

Dissertations

Grounded theory methodology was used to explore women’s internalization of religious messages regarding their sexuality. Two research questions served as the guide for this study: how are women’s sexual self-views informed by their religious teaching, and how are these messages, along with their experiences, lived in them sexually, psychologically, and spiritually? Eleven women (ages 30-74) were chosen who had been raised in a Western Christian tradition in the US (8 Protestant, 3 Catholic). Participants were interviewed through an in-depth three-interview process to gain an understanding of their experiences and how they resolved their concerns with sex and spirit. The findings …

The Effect Of Hiv Knowledge And Hiv Attitudes On African American Women’S Decision To Hiv Test, Lisa Ann Green

Dissertations

Centers for Disease Control (2011a) Surveillance report revealed African American women comprised 63% of new HIV cases among women; 65% of African American women were infected with HIV transmitted by heterosexual sex; yet represent 13% of the female population in the United States. An existing data set was examined from a sample of 761 African American women with a history of drug use at high risk to acquire or transmit HIV and/or STDs to determine 751 women’s knowledge and attitudes about risky sexual behaviors, factors influencing a decision to HIV test, and the influence of sex trading on the decision …

Oxidative Stress In Avian Embyros, Toshi Tsunekage

Dissertations

Oxidative stress has been implicated in mediating trade-offs in the evolution of life histories. Oxidative stress results from an imbalance in the production of free radicals and an organism’s antioxidant defenses. Higher metabolic rates associated with more rapid growth and shorter development periods may increase oxidative stress and accumulated cellular damage in embryonic tissues. In my dissertation I explored oxidative stress and antioxidant defenses in avian embryos. I measured levels of oxidative stress in tissues of different stage embryos of Japanese quail (Coturnix japonica), and tested if patterns of lipid peroxidation could be explained by changes in the developing embryo’s …

Environmental Impacts And Carry-Over Effects In Complex Life Cycles: The Role Of Different Life History Stages, Nnaemeka F. Ezeakacha

Dissertations

A challenge faced by organisms with complex life cycles is how environmental factors experienced at an earlier life stage affect the fitness at that stage or are carried over to subsequent life stages. I used container-inhabiting mosquitoes: Aedes albopictus, Aedes aegypti, Aedes triseriatus and Culex quinquefasciatus to study the interactions and performance of life history stages under specific environmental factors. I investigated the effects of egg-desiccation tolerance on egg viability and larval performance in the Aedes mosquitoes. I found increase in egg hatch rate with relative humidity and interaction between relative humidity and egg storage period. Larval performance …

Stable Isotope Ratios As A Proxy For Human Geographic Provenance: Biogeographical Evidence From The 2h, 18o, And 13c Signatures In Modern Human Teeth, Anastasia Holobinko

Dissertations

The positive identification of a decedent is paramount to a forensic investigation in which human remains have been recovered and must be identified. Due to increasing global mobility in the world's populations, it is not inconceivable that an individual might die far away from his or her home. Pinpointing an individual's geographic origin may contribute to definitive forensic identification of contemporary human skeletal remains in cases where dental records and other means of identification are either unavailable to law enforcement personnel or do not yield immediate results. Stable isotope analysis of biogenic tissues such as tooth enamel and bone mineral …

Retention Of Community College Students In Online Courses, Sarah Krajewski

Dissertations

The issue of attrition in online courses at higher learning institutions remains a high priority in the United States. A recent rapid growth of online courses at community colleges has been instigated by student demand, as they meet the time constraints many nontraditional community college students have as a result of the need to work and care for dependents. Failure in an online course can cause students to become frustrated with the college experience, financially burdened, or to even give up and leave college. Attrition could be avoided by proper guidance of who is best suited for online courses. This …

Design Of Oppnet Virtual Machine For Opportunistic Resource Utilization Networks: A Universal Standard For Application-Level Resource Sharing, Mai A. Alduailij

Dissertations

Opportunistic resource utilization networks or oppnets are a paradigm for specialized ad hoc networks. The Oppnet Virtual Machine (OVM) is a collection of primitives designed to create a middleware for application-level resource acquisition by oppnets and oppnet-enabled systems and devices (where the latter are defined as the computational entities able to communicate with other oppnets or oppnet-enabled entities). Acquisition of communication resources is the foundation for acquisition of other resources.

The OVM primitives can be downloaded by any computational entity—making entity oppnet-enabled. OVM ensures that oppnet-enabled entities can communicate and acquire resources in an opportunistic and ad hoc manner. This …

Investigating The Impact Of Reflexive Practices On College Students In A Science Laboratory Course, Chandrani Mishra

Dissertations

Emphasis on professional practices to develop students’ professionalism is currently a major focus of higher education. Studies have shown the benefits of reflexive practices in classroom to facilitate the development of students’ professional attitude or identity in some fields. Reflexive practices involve students in self-reflection where he/she reflects on his/her own actions. Little investigation about the benefits of reflexive practices in the development of students’ scientific identity in a science class led to my investigation. Development of a scientific identity of students and their overall interest and motivation in science is deemed essential for retaining students in STEM fields.

My …

Redefining Significance: Experiences Of Humanities Faculty Engaged In Undergraduate Research, Susan Mendoza

Dissertations

Programs that actively engage students in research and scholarship are the touchstone for integrating undergraduate education with authentic scholarly inquiry. Recent empirical studies demonstrate that undergraduate research experiences (URE) are related to increased student learning and development, increased levels of retention, increased enrollment in graduate school, and increased understanding of research as a vocation and profession. However, these seminal studies focus on URE in the STEM (science, technology, engineering, and math) disciplines. Although there are some studies that explore undergraduate research in the social sciences and humanities, the accepted models and best practices of undergraduate research are entrenched in the …

Creating A Framework For Success For High School African American Males: A Policy Advocacy Document, Ilandus Hampton Sr.

Dissertations

The policy advocacy document is an alternative to the traditional doctoral dissertation. This approach arose from the educational administration preparation reform agenda which calls for more thoughtful approaches to educational policy development, a concern that educational leadership express itself in a moral context, and a desire to develop reflective practices in administration. (Browder, 1995). This document attempts to ensure public schools, high schools in particular, are providing African American males with the skills and knowledge necessary to be academically successful so that they are given the opportunity and support necessary to achieve economic and social advancements throughout life. The policy …
