A Non-Weight Centered Approach To Modifying Eating Attitudes In Polycystic Ovarian Syndrome, Jo'quishia A. Lethermon

Dissertations

Polycystic Ovarian Syndrome (PCOS) is an anovulatory disorder characterized by insulin resistance and endocrine dysfunction. Infertility and abnormal weight gain in women of childbearing age are often a result of PCOS, impacting quality of life and posing potential long-term health sequelae. Prescribing weight loss has been adopted by clinicians as an effective intervention to improve insulin resistance. For some patients, this practice has led to the negative effects of weight cycling and disordered eating attitudes which can result in long term adverse cardiometabolic outcomes. A quasi-experimental pre-and-post-test study was conducted to evaluate how a non-weight centered program influences eating attitudes …

Convergence And Divergence: Comparative Analysis Of Procedural Rule Changes Of The Hong Kong And Singapore International Arbitration Centers Within The Framework Of Neo-Institutional Theory, Phillip Hoang Tran

Dissertations

International commercial arbitration (ICA) plays an essential role in resolving disputes between companies engaged in complex, cross-border business transactions. It offers an efficient, neutral, and enforceable mechanism for resolving disputes across different legal and cultural backgrounds. ICA is generally conducted at international arbitration centers located throughout the world. According to the extant literature, there is convergence of procedural rules among these centers. Sabharwal and Zaman (2014), for example, claim increasing convergence of procedural rules among all the major arbitration centers. Similarly, Sharma (2021) proposes that this convergence helps build the international arbitration system. However, there is a near absence of …

Borderland Voices: Exploring The Educational Journey Of Transfronterizx Students, Families, And Educators For Enhanced Engagement And Empowerment, Sobeida Velazquez

Dissertations

Transfronterizx students and their families cross the U.S.–Mexico border for academic, economic, social, cultural, and linguistic reasons. Socioeconomic disparities, deportation, and work have propelled some families to live in Mexico and enroll their U.S.-born children in U.S. schools to provide more socioeconomic opportunities in the United States. Educators of transfronterizx students are uniquely tasked to work with these nontraditional students. Moreover, transfronterizx students and their families have distinct needs in U.S. schools; as such, there is a need for further research on the transfronterizx experience in the U.S. K–12 system. This qualitative narrative inquiry study aimed to understand the experiences …

A Quantitative Correlational Study Of Job Satisfaction Among Critical Care Nurses In Hawai'i, Hazel Downing

Dissertations

One way of reducing nurse shortage and providing effective patient care within critical care units includes addressing the relationships between job satisfaction and nurse socio-demographics. The current quantitative correlational study identified a moderate level of overall job satisfaction among critical care nurses in Hawaii. The highest level of job satisfaction was in flexibility of scheduling and lowest in child care facilities. Rejection of the null hypothesis for six of the eight hypotheses suggested presence of a relationship between socio-demographics and the subscales of job satisfaction. The linear combination of the 10 socio-demographics does not predict the rewards and the professional …

Why Not The School-To-Scholar Pipeline? Changing The Narrative Through School Leadership, Marne Renee Foster

Dissertations

The overrepresentation of Black students in exclusionary practices in public K–12 education, such as detention, suspension, expulsion, and misplacement into special education, contributes to the school-to-prison pipeline (STPP). This phenomenon leads to truancy, academic failure, and involvement in the juvenile justice system. In contrast, the school-to-scholar pipeline (STSP) has an inverse relationship with the STPP and views students as scholars in training, ultimately linking them to careers or college. Research has indicated that school administrators’ mindsets, along with teacher bias, play a significant role in perpetuating exclusionary practices and racial disparities (Gullo & Beechum, 2020; Skiba, Chung et al., 2014). …

Culturally Sustaining Pedagogical Practices In Early Literacy Classrooms: A Qualitative Case Study Of Two Kindergarten Classrooms, Elizabeth Carlton Phd

Dissertations

Students who attend school possess their own “funds of knowledge” from their home life and prior experiences (Moll et al., 1992). Yet, learners from diverse cultural and linguistic backgrounds are not viewed from a strengths-based perspective but rather a deficit perspective. The deficit perspective perpetuates the oppression and marginalization of students of color and multilingual students. Using a qualitative comparative case study research design, the study is rooted in the tenets of Critical Pedagogy (Freire, 2000), Critical Literacy, and Culturally Sustaining Pedagogy as it sought to uncover insights into asset-based instructional strategies that allow multilingual learners opportunities to participate equitably …

From Injustice To Social Justice Education: The Journey Of Formerly Incarcerated Women Of Color In Community College, Hossna Sadat Ahadi

Dissertations

There is a growing rate of women of color in the U.S. prison system—their intersectional identities are hypercriminalized surrounding the nexus of oppressive barriers they experience (Annamma, 2017). The lack of awareness, understanding, and advocacy for carceral-impacted women of color in higher education has engendered an erasure. This qualitative research study explored and elevated the lived experiences and intersectional identities of formerly incarcerated women of color in postsecondary education. Through the lens of Latino critical race theory (LatCrit) and Chicana feminism, four methods of data collection took place—surveys, cajitas, testimonios, and reflective journaling. Formerly incarcerated women of color experienced the …

The Lived Experience Of Patients In Feeling Empathy From Nurses When Receiving Care Via Telehealth, Donna L. Cutting

Dissertations

With the increased use of telehealth, particularly telenursing, there is a lack of literature regarding the portrayal and deliverance of empathy and compassion from the nurse to the patient when physical separation exists, such as when the nurse and the patient are in different locations and "seeing" each other through use of technology.

The aim of this qualitative, phenomenological dissertation study was to describe the lived experience of patients feeling empathy or not from nurses when receiving care via telehealth. Watson's Human Caring Science was the nursing theory used to guide this study. The research question was: What is the …

Second Victim Syndrome: Nurses Suffering In Silence, Matthew Riehm

Dissertations

Medication errors are inherent in health care due to human fallibility and inherent systemic complexities. Nurses are often unjustly blamed after committing a medication error despite the multitude of contributing factors. Formal education and healthcare organizations focus on preventing medication errors, but little has been done to support nurses involved in these tragic incidents. Recent cases, including RaDonda Vaught and Kimberly Hiatt, demonstrated the victimization of nurses after committing medication errors that plague the healthcare system potentially causing profound psychological trauma, often known as Second Victim Syndrome, SVS. There is limited research on the phenomenon of SVS in nursing due …

Impact Of Social Determinants Of Health On Skill Of Involvement: Differences In First Year Adn And Bsn Nursing Students In Rural Oklahoma, Cynthia Brown

Dissertations

The impact of Social Determinants of Health (SDOH) on Skill of Involvement (SOI) has not been adequately studied in nursing education.
