An Exploration Of Factors Contributing To Service Longevity At Asia-Pacific International University, Ritha Maidom Jan 2023

An Exploration Of Factors Contributing To Service Longevity At Asia-Pacific International University, Ritha Maidom

Dissertations

Problem

In educational institutions of higher learning, turnover is seen as a double-edged sword that brings both benefits and problems. While turnover allows the opportunity to bring in a new employee who may be able to benefit the institution more than the one being replaced, the process of finding a replacement tends to be costly in terms of time, energy, and financial resources. As a young institution, Asia-Pacific International University (AIU) found turnovers challenging in more than one way because of its lack of stability in areas such as finance and human power. It could benefit from a clearer understanding …


Predictors Of Statistics Anxiety Among Graduate Students In Saudi Arabia, Rabab Abdulghani Jan 2023

Predictors Of Statistics Anxiety Among Graduate Students In Saudi Arabia, Rabab Abdulghani

However, this study aims to identify specific factors that could decrease student statistics anxiety and enhance positive attitudes and self-efficacy toward statistics. The study developed a conceptual model to predict statistics anxiety among graduate students in educational and social science …


Toward A Biblical And Missiological Framework For Transformational Advocacy In The Seventh-Day Adventist Church, Michelet William Jan 2023

Toward A Biblical And Missiological Framework For Transformational Advocacy In The Seventh-Day Adventist Church, Michelet William

Dissertations

Problem

Adventists have been inconsistent in dealing with inequality and injustice in society, swaying between silence, accommodation, positional statements, and direct advocacy approaches. Although advocacy has become more prominent among Adventist thinkers since the end of the twentieth century, there is a lack of empirical data which answer questions related to contemporary Adventists' beliefs and practices in relation to advocacy in the context of mission. Concomitantly, there does not yet exist a documented or articulated Adventist missiological perspective on advocacy.

Research Questions

(1) What part, if any, has biblically-based social advocacy played in Adventist mission history? and (2) What do …

Graduate School of Oceanography Faculty Publications

Marine heatwaves are causing recurring coral bleaching events on tropical reefs that are driving ecosystem change. Yet, little is known about how bleaching and subsequent coral mortality impacts the spatial properties of tropical seascapes, such as patterns of organism spatial clustering and heterogeneity across scales. Changes in these spatial properties can offer insight into ecosystem recovery potential following disturbance. Here we repeatedly quantified coral reef benthic spatial properties around the circumference of an uninhabited tropical island in the central Pacific over a 9-year period that included a minor and subsequent severe marine heatwave. Benthic communities showed increased biotic homogenisation following …

"The Power To Heal And Cure": Adaptations Of Western Therapy By American Indian And Alaska Native Therapists, Calleaghn B. Kinnamon Jan 2023

"The Power To Heal And Cure": Adaptations Of Western Therapy By American Indian And Alaska Native Therapists, Calleaghn B. Kinnamon

Antioch University Dissertations & Theses

The legacy of colonialism has created a modern-day reality where Indigenous populations of the United States (US) experience mental, physical, and emotional distress at disproportionately higher rates than other cultural groups in the country. Increased distress translates to an increased need for supportive services. Because the field of Western Psychology is based in colonialistic EuroWestern worldviews which positions that worldview as superior, Indigenous clients and communities have often experienced further harm in their encounters with mental health services. In recent decades, there has been increasing attention to adapting research, training, academic and clinical work in ways that are culturally appropriate …


Autism Paradigms And Mental Well-Being Among Autistic Adults: A Quantitative Exploration, Libbey Walker Jan 2023

Autism Paradigms And Mental Well-Being Among Autistic Adults: A Quantitative Exploration, Libbey Walker

Antioch University Dissertations & Theses

Autistic populations experience significant mental health challenges. A growing body of research supports addressing autistic mental health problems using the framework of minority stress theory, the social model of disability, and the neurodiversity paradigm (e.g., Botha & Frost, 2018; Cage et al., 2018). This quantitative study explored how identification with the neurodiversity paradigm versus the pathology paradigm related to mental well-being in autistic adults.

What Does It Look Like For Mental Healthcare Organizations To Be Healthy Places To Work? An Action Research Study, Stephanie L. Fox

Antioch University Dissertations & Theses

Mental healthcare organizations have a reputation for being unhealthy places to work. The irony of this reputation is keenly felt by its workforce who report unsustainable workloads, high levels of stress, and lack of support or engagement from higher-level leadership. As a mental healthcare provider now in a position of leadership, who has worked across all levels of care within the sector, it was of interest to me to explore how a mental health organization can become a healthier and more sustainable place to work. I approached this study with the assumption that if an organization was healthy and intentional …


Eating Change: A Critical Autoethnography Of Community Gardening And Social Identity, Jessica Gerrior Jan 2023

Eating Change: A Critical Autoethnography Of Community Gardening And Social Identity, Jessica Gerrior

Antioch University Dissertations & Theses

Community gardening efforts often carry a social purpose, such as building climate resilience, alleviating hunger, or promoting food justice. Meanwhile, the identities and motivations of community gardeners reflect both personal stories and broader social narratives. The involvement of universities in community gardening projects introduces an additional dimension of power and privilege that is underexplored in scholarly literature. This research uses critical autoethnography to explore the relationship of community gardening and social identity. Guided by Chang (2008) and Anderson and Glass-Coffin (2013), a systematic, reflexive process of meaning-making was used to compose three autoethnographic accounts. Each autoethnography draws on the author’s …

Considering the ongoing environmental crisis, determining if forest bathing increases connectedness to nature is a critical expansion of forest bathing research, as connectedness to nature is linked to environmental care and concern. This study investigated the possibility that forest bathing, a nature-based mindfulness practice, could increase adolescent mental well-being and connectedness to …


Understanding How Secular Spirituality Transforms Intergenerational Parenting Styles, Barrie Birge Jan 2023

Understanding How Secular Spirituality Transforms Intergenerational Parenting Styles, Barrie Birge

Antioch University Dissertations & Theses

A family is a relational system that shapes a child’s development, and it is well-established that parenting directly exasperates or reduces a child’s internal and external behaviors (Foran et al., 2020; Rikuya & Toshiki, 2018). Parents are influential figures during childhood and adolescence and play a key role in their children’s development (Baumrind, 1978; Maccoby & Martin, 1983). Therefore, it is of great concern that developmental challenges in children and adolescents in the U.S. continue to increase. The Centers for Disease Control (2019) confirms adolescent mental health and suicide variable trends in the U.S. continued to increase significantly between 2009 …

Persistent organic pollutants (POPs) are recognized as pollutants of global concern, but so far, information on the trends of legacy POPs in the waters of the world has been missing due to logistical, analytical, and financial reasons. Passive samplers have emerged as an attractive alternative to active water sampling methods as they accumulate POPs, represent time-weighted average concentrations, and can easily be shipped and deployed. As part of the AQUA-GAPS/MONET, passive samplers were deployed at 40 globally distributed sites between 2016 and 2020, for a total of 21 freshwater and 40 marine deployments. Results from silicone passive samplers showed α-hexachlorocyclohexane …

An Analysis For Understanding The Impacts Of Healthcare Leader Emotional Intelligence On Employee Engagement: Differences Between Clinical And Non-Clinical Employees, Adam Wilkins

Doctor of Business Administration Dissertations

While leadership theory and its applications have been studied by academic researchers since the 1800s, the study of emotional intelligence (EI) did not become a focus until 1990. Since EI’s conceptualization, this form of intelligence has remained a key focus area in the study of what motivates employees to best keep them engaged in their work. However, some critical aspects of the relationship between EI and employee engagement have not yet been explored. This research provides insight into the importance of EI in healthcare leadership. The narrowed focus of this study provides a better understanding of what role, if any, …
