Collective Case Study Career Critique Of Social Entrepreneurs Who Are Gifted Adults, Joi Lin

Electronic Theses and Dissertations

This dissertation describes a qualitative research study that grows our understanding of the career development experiences, supports, and barriers of social entrepreneurs who are gifted adults (SEGA) so that we may nurture the career development of future SEGA. Research questions for this study probed the career development experiences, supports, and barriers of SEGA and the shared social value they create. The conceptual frameworks for this study are the ecological model for human development (Bronfenbrenner, 1979); the theory of positive disintegration (Dąbrowski, 1964/2016); social cognitive career theory (SCCT; Lent et al., 1994); the perceived instructional arc (Uhrmacher et al., 2017); and …

Cannabis Exposure During Pregnancy And Neural Mechanisms Of Parenting: Assessing Neural Responses To Infant Cues And Parenting Outcomes, Shannon Powers

Electronic Theses and Dissertations

As legalization of cannabis and cannabinoids spreads in the United States, access and use of cannabis during the prenatal period has increased. There is limited knowledge on the effects of prenatal cannabis use on the parental brain. One way to identify potential effects of cannabis on parenting is through studying parenting brain functions and behavior. Cannabis use disorder (CUD) has been shown to be associated with lower positive parenting and lower sensitivity to infants, but it is unclear by what mechanisms. The following two studies address this gap in knowledge by examining the association between cannabis use during the prenatal …

Radical Hospitality: Height And Excess Of The Other And The New Host Self, Diako Alikhani

Electronic Theses and Dissertations

Drawing on Emmanuel Levinas’ ethical framework and its emphasis on the “height and excess” of “the Other,” this thesis explores and develops a sense of “radical hospitality” in Levinas and across Judaism, Christianity, and Islam. In particular, the thesis explores how encounter with the Other is not only marked by an overwhelming excess, but one which transforms the subject into what I call a “New Host Self:” Where the self is the host who greets the stranger with hospitality, it is ultimately the stranger—the refugee, the migrant—who transforms the host into someone new. Here, the host ultimately receives a gift …

Honoring Indigenous Worldview: Cultural (Un)Responsiveness In Gifted Education, Vicki Boley

Electronic Theses and Dissertations

Many working understandings of giftedness exist within dominating Western frameworks, gatekeeping gifted education from students who do not “fit” inside such frameworks (Owens et al., 2018; Rinn et al., 2020; Sternberg et al., 2021). As a result, K- 12 Native American, Alaska Native, and Native Hawaiian students are underrepresented in gifted education programs (Sternberg et al., 2021) and overrepresented in special education programs (NCLD, 2023). When considering Indigenous students in particular, Western orientations surrounding giftedness perpetuate assimilation, dominance, and continued colonization (Battiste, 2013; Dunbar-Ortiz, 2014; Gentry & Gray, 2021a). Leveraging Positionality and The Pedagogy of Listening as conceptual frameworks, this …

Reconciling Moral Dissonance: A Framework For Re-Integrating Moral Orientation With Life Agency During Warfighters’ Struggles With Military Moral Injury, Jeffrey L. Zust

Electronic Theses and Dissertations

This dissertation uses case studies to critically examine the Three Mirror Model (TMM) as a framework for understanding the formation and healing of Military Moral Injury (MMI). I adapt the work of Stephen Brookfield and Neal Krause to evaluate using the TMM as a methodology for dealing with the complex issues of MMI within a military deployment cycle (training, warfighting, and healing) (Brookfield 2012, 2017; Krause 2022). Specifically, I use theorists, researchers, healers, and warfighters as key stakeholders to identify and critically examine the intersections of disciplines and the subsets of models where warfighters’ moral orientations and moral agency form …

Picturesque Portraiture: The Composition Of Reality In Hawthorne, Melville, And James, Angela Michael Gattuso Densmore

Electronic Theses and Dissertations

Throughout the nineteenth century, American artists were tangled in debates regarding the representation of reality. The Hudson River School of picturesque landscape painters tackled this dilemma with a compromise formula which used the real objects of nature to create ideal scenes. This dissertation applies the same picturesque formula to select examples of literary portraiture, studied under the concept of “picturesque portraiture.” Whereas the Hudson River compromise resulted in an ideal perception of reality, however, the picturesque portraits composed by nineteenth-century authors Nathaniel Hawthorne, Herman Melville, and Henry James attempt to invoke a non-idealized “actual” reality of the portrait subject’s person …

Sources Of Sexual And Romantic Education: Associations With Sexual Minority Men’S Sexual Experiences And Romantic Relationship Quality, Charlie Huntington

Electronic Theses and Dissertations

Individuals with sexual minority identities experience a variety of poorer mental and physical health outcomes, including those related to sexual and romantic quality, relative to heterosexual individuals (Beaulieu et al., 2017; CDC, 2021). These poorer romantic, sexual, and psychological outcomes may be attributable in part to lacking access to affirmative and relevant modeling of sexual minority experiences, such as through sex education (Gillespie et al., 2022; Keiser et al., 2019). This study aimed to understand how sexual minority men learn – in ways potentially both helpful and unhelpful – about romantic relationships and sexual activity, and how these experiences are …

Culturally Responsive Coaching: Supervision With A Cultural Lens, Jouanna Crossland-Wells

Electronic Theses and Dissertations

Culturally Responsive Practices (CRP) are a focal point for many districts across the country. The emphasis of CRP is on how the institution enacts policies and practices for the benefit of the students they serve. This study views CRP from a different lens. The focus of this study is to 1.) center the voice of Black teachers and 2.) explore culturally responsive practices for the support and edification of the teacher from their coach/supervisor. The eight Black teacher participants and their instructional coaches engaged in interviews discussing current coaching models and the dynamics of their coaching relationships.

Mother-to-child transmission (MTCT) of human immunodeficiency virus (HIV) continues to be the primary conduct that HIV is transmitted to children worldwide. The problem of HIV/acquired immunodeficiency syndrome (AIDS) is having a great impact on the world's children. The prevalence of HIV/AIDS in Malawi continues to be a serious public health issue, especially for expectant mothers. The health outcomes of mothers and children remain significantly threatened by vertical HIV transmission, even with improvements in preventive and treatment efforts. The purpose of this thesis was to explore the experiences of HIV-positive pregnant women in Malawi. I conducted semi structured interviews with thirteen …

Ensemble Perception Of Emotion: Incidental Effects Of Social Identity, Spencer T. Dobbs

Electronic Theses and Dissertations

Research in vision science suggests that people possess a perceptual mechanism – ensemble perception - which enables them to rapidly identify the characteristics of groups (e.g., emotion, sex-ratio, race-ratio). This work examined whether ensemble perceptions of groups are driven by the characteristics of group members whose behavior is most likely to impact the perceiver. Specifically, we predicted that more self-relevant group members would be weighted more heavily in ensemble perceptions than less self-relevant group members. Study 1 (n = 83) found that young adult participants’ ensemble perceptions of emotion were biased in favor of more self-relevant (younger adult) group …

Leadership In Extreme Contexts: An Emerging Typology, Ashley Williams

Electronic Theses and Dissertations

This study investigates the relationship between leadership and extreme contexts through the lens of rural hospitals facing environmental jolts. Rural hospitals offer a unique setting for this research, given their inherent geographic isolation, lack of resources, and the critical role these facilities play in their communities. Through a qualitative analysis of interviews with Chief Executive Officers of rural hospitals, this research takes a grounded approach to build theory surrounding how leadership not only shapes but is shaped by extreme contexts and environmental jolts. The research results in four primary contributions. Namely, this study extends existing typologies on leadership in extreme …

Extending The Utility Of Ant Colony Optimization Through The Incorporation Of An Intraclass Correlation Coefficient To Assess For Rater Consistency, Mark Leveling

Electronic Theses and Dissertations

Ant Colony Optimization (ACO) is a flexible algorithm designed to solve complex combinatorial problems. While the method was derived from the behavior of ants by researchers in the field of computer science, its application to solving complex combinatorial problems is widespread in a growing number of fields in behavioral science, including psychometrics. Over the last two decades, psychometricians have adapted ACO to measurement model specification problems with the intention of generating measurement models that express measurement model fit and reliability within the standards of what is considered acceptable. Additionally, psychometricians have used ACO to generate shortened versions of existing measures …

The Effects Of Covid-19 On Asian American Perception Of Mental Health, Emily Tseung

Electronic Theses and Dissertations

This study describes a qualitative study using a grounded theory, constructivist approach, which sampled (N = 6) Asian American college students who lived in the United States during the peak of the COVID-19 pandemic. Research shows that COVID significantly impacted the Asian American perception of mental health, including mental health help- seeking behaviors and discrimination experienced. The long-term effects of this are still largely unknown. In depth, semi-structured interviews were used to explore the lived experiences of these Asian Americans. Qualitative analysis revealed thematic differences for the following themes: (a) experience with mental illness, (b) mental health help- seeking …

An Exploration Of Rural Advanced Placement Differentiation, Kristin M. Shapiro

Electronic Theses and Dissertations

Advanced Placement classes are introductory college courses taught in high school. Over 60% of all secondary gifted programs report utilizing AP classes as part of their program offerings (Callahan et al., 2017). Despite the prevalence of AP courses, there is no exact match between this particular type of programming and the needs of gifted learners (Gallagher, 2008). The use and occurrence of AP programs across the United States have not been equal, with subsequent underrepresentation of underserved groups, including rural students (Gagnon & Mattingly, 2016) in AP classes. Rural gifted students benefit from all the same classroom differentiation techniques that …

Conducting Culturally Responsive, Strengths-Based Assessment In Schools, Eileen Cullen

Electronic Theses and Dissertations

Special education assessment has a significant impact on the lives of children with disabilities and their families. However, traditional assessment practices have been critiqued as being deficit-based, overly focused on “labeling” students, and failing to provide a holistic understanding of the student. Assessment models such as strengths-based assessment (SBA) and culturally responsive assessment (CRA), have potential to addresses these critiques and be more appropriate for the growingly diverse school population. Despite this, these models of assessment are under studied and there is a lack of clear guidance for how practitioners should implement them.

In these manuscripts, CRA and SBA are …

Changing The Narrative: Student Empowerment In Unequal School Contexts, Stephanie A. Nisle-Mikos

Electronic Theses and Dissertations

Educational experiences affect a wide variety of life outcomes for individuals. The type of education an individual receives influences their occupation, the neighborhood in which they live, and even their risk of mortality (National Research Council, 2013; Sasson, 2016). In particular, the life trajectories of students who attend high-poverty schools are not the same as youth who attend schools with greater resources (National Center for Education Statistics [NCES], 2013; Taylor, 2005). In this dissertation, I provide a brief background on current rates of disproportionality in education and examine how specific theoretical constructs and educational policies may be used to explain …

Progressive Paradox In Political Rhetoric: The Hart-Celler Immigration Act Of 1965, Amanda Rolston Henderson

Electronic Theses and Dissertations

This dissertation investigates the interplay between U.S. norms for inclusion, the embedded role of religion within these norms, and how political rhetoric challenges or sustains them. Using a historical lens, I outline key moments in U.S. history, unravel central ideologies entrenched in U.S. narratives, and illuminate the ideographic function of the key concepts land, family, and work. These terms serve as conduits for conveying complex systems of meaning, which are entrenched in societal assumptions and concretized through political discourse and action.

These dynamics are demonstrated in a case study of the discourse surrounding the Hart-Celler Immigration Act …

Balancing Act: Navigating Employee Autonomy And Neglect, Lekshmy Sankar

Electronic Theses and Dissertations

The fine line between granting employee autonomy and inadvertently falling into patterns of neglect presents a complex challenge within organizational leadership. This study explores the question: What do leaders perceive as effective strategies for providing autonomy to remote employees without being perceived as neglecting them? Employee autonomy empowers employees to make decisions, while leader neglect towards subordinates (LNS) is defined through this research as a gradual decrease in a leader's interest or effort in sustaining positive relationships with employees. Navigating this balance is crucial to maintaining employee engagement.

This qualitative study uncovered nuanced perceptions on this issue using a grounded …

The Entrepreneur’S Burden: Investigating The Interplay Between Impostorism And Entrepreneurial Identity, Megan Laura Weber

Electronic Theses and Dissertations

Entrepreneurship is often portrayed as a glamorous pursuit of success but conceals a darker side, exacerbated by impostorism, characterized by challenges, identity conflicts, and diminished well-being. This "dark side" of entrepreneurship is seldom explored due to our collective fascination with the central figure of the entrepreneur. Impostorism is a prevalent phenomenon among individuals who perceive that their role is beyond their capabilities and fear being exposed as a "fake." Impostorism can have negative consequences, including self-sabotage, missed opportunities, and difficulty in seeking help or support, which can impact the ability of entrepreneurs to take entrepreneurial action and experience well-being.

Using Self-Assessment Tools And Complementary Alternative Therapy For Chronic Migraines In Menopausal Women, Krystal Rachelle Bridwell

Electronic Theses and Dissertations

Abstract

Migraine headaches are ranked as one of the highest disabling conditions in the United States. Women who are in the perimenopausal transition phase have a higher prevalence of disabling migraines that can result in a decreased quality of life, loss of income, decreased productivity, and a higher risk for emotional difficulties. The gap in practice is the lack of education on complementary alternative medicine (CAM) and the use of a migraine diary to recognize individual symptoms as a substitute or cotherapy with pharmacologic treatments. The purpose of this scholarly project was to improve clinical practice and outcomes for perimenopausal …

The Effect Of Novel Microtubule Modulators On Experimental Lewy Body Disease, Anuj S. Jamenis

Electronic Theses and Dissertations

In Lewy body disorders, α-synuclein aggregates are believed to destabilize the microtubular framework. However, microtubules are a challenging therapeutic target, as excessive rigidity or flexibility afforded by microtubule modulators may be neurotoxic. Thus, the objective of the present study was to evaluate dual-acting microtubule- stabilizing/destabilizing agents in cellular and animal models of early-stage Lewy body disease.

In Aim 1 we tested the dual-acting tricylic pyrimido[4,5-b]indole analogs AG161-47 and AG161-41 in an in vitro preformed fibril induced model of Lewy body disease. We found that both compounds reduced preformed fibril-seeded α-synucleinopathy without toxicity in primary hippocampal cultures. AG161-47 subtly impacted microtubule …

A Gift Not Given: An Examination Of Disproportionality For Black Students And Gifted Education Through The Lens Of Representation And Improvement, Casey Weiss

Electronic Theses and Dissertations

Giftedness is a particular trait giving designation to a specific group of people in a school population. While identification methods vary from state to state, the status of being gifted is granted to some students, creating a dichotomy of those who receive gifted services and subsequent privileges and those who remain left out. Historically, Black students and other marginalized populations have had less participation in gifted programs. The literature highlights several factors connected to inequity in giftedness including lack of a cohesive definition of the term (or even if the concept of giftedness is real or socially constructed), nomination and …
