An Integrated Exploration Of The Contextual, Relational, And Individual Factors That Impact High School Completion Among African Americans, Lesley B. Winchester

Theses and Dissertations

African American students are consistently reported as having among the lowest high school graduation rates when compared to other races (U.S. Department of Education, 2018). While many studies have sought to explore the potential risks of high school dropout, the intention of this study is to examine the factors that support the exemplary resilience of those students who do complete high school. The present study adopts the framework of García Coll et al.’s, (1996) integrative model of developmental competencies in minority children, as it seeks to identity whether and how contextual (spiritual, educational, cultural); relational (caregiver psychological and physical …

Mef2-Bound Genes May Influence Ethanol Sedation In Drosophila Melanogaster, Katlyn M. Myers

Theses and Dissertations

Alcohol Use Disorder (AUD) is a global health issue that affects millions of people every year. This disorder has serious negative mental and physical consequences. Currently, treatment options for this disorder are largely limited to psychological therapy, with very few medications available to treat it. Being able to identify the environmental and genetic components that influence AUD can help improve diagnosis and treatment options. Previous studies in humans have shown a link between initial sensitivity and risk for alcohol abuse. Our laboratory uses Drosophila melanogaster as a model to study the genetic and environmental components of alcohol-related behaviors. Previous lab …

Estimating Response Status In Sequential Multiple Assignment (Smar)-Like Trials, Keighly Bradbrook

Theses and Dissertations

Sequential, multiple assignment, randomized trials (SMARTs) allow investigators to develop and compare experimental treatment regimens in which individuals are successively randomized to different treatments based on some set of predetermined rules. The rules used to make decisions on when and how to switch treatments are based on a chosen set of tailoring variables. Although not always true, intermediate response is commonly used as the primary tailoring variable as it is often predictive of future treatment success. As such, successful implementation depends on identifying patients who respond to treatment, though in some situations such mechanisms may not exist. Further, patient-level covariates …

Examining The Role Of Racial Discrimination In Obesity Treatment Disparities Among African American Emerging Adult Women, Kristal Brown

Theses and Dissertations

The overarching goal of the proposed work was to examine how racial discrimination contributes to disparities in adiposity and treatment response between non-Hispanic Black and non-Hispanic White emerging adult women, and to identify potential protective and risk factors that might moderate this association—all in service of improving lifestyle interventions for this high-risk population. Project aims were achieved across three studies. In Study 1, we extracted data for emerging adults (N=261, BMI=33.8+4.9 kg/m², age=21.9+2.1 years) who recently completed a BWL program adapted specifically for emerging adults and compared treatment outcomes for non-Hispanic White and non-Hispanic Black women. In Study …

Flexible Methods For Accounting For Distributional Misspecification Of The Response-Adaptive Randomization Ratio In Two-Arm Clinical Trials With Continuous Or Survival Outcomes, Victoria C. Garcia

Theses and Dissertations

Optimal response-adaptive randomization (RAR) is used in clinical trials (CTs) to balance ethics and power by randomizing patients according to the unknown population parameters of an assumed parametric response distribution selected prior to data collection. If the distribution of the observed response data is misspecified, the resulting randomization may produce unanticipated trial characteristics. This dissertation introduces flexible estimators of the optimal RAR ratio that adjust for such misspecification.

When observed response data were continuous in nature, sample moments were estimated from a continuous fit of the empirical CDF. These sample moments then served as the operands for the first flexible …

Integration Of Multi-Omic Platforms To Understand The Regulation Of Genes In Human Disease, Eva Lancaster

Theses and Dissertations

Epigenetic mechanisms have been hypothesized to modify gene expression (GE) in response to both genetic variation and environmental exposures, ultimately contributing to the development of complex traits. Epigenome-wide association studies (EWAS) aim to test the theory that marks of DNA methylation (DNAm) have downstream consequences that result in the development of complex diseases. Although these methods have been successful in identifying DNAm patterns in complex traits, specific molecular mechanisms involved in the etiology of complex diseases remain unidentified. This knowledge gap does not originate from a lack of DNAm-trait associations, but rather stems from study design issues that affect the …

Knowledge And Skill Predictors Of Voice Behavior: Voice As An Upward Influence, Zitong Sheng

Theses and Dissertations

Abstract

In recent years, there has been a growing body of research focused on improving our understanding of employee voice behavior. Yet this literature focuses mainly on factors that influence employees’ decisions regarding whether to speak up (i.e., quantity of voice behavior), rather than factors that influence whether voice behavior turns out to be effective. As a result, job attitudes and personality characteristics have been identified as the major personal factors predicting voice behavior. The current study contributes to the voice literature by viewing voice from an upward influence angle, examining the influences of the quality of content and …

A Comparison Of Computer- And Interviewer-Administered Measures To Identify Heavy/Problem Alcohol And Other Drug Use In Primary Care Patients, David J. Pomm

Theses and Dissertations

Substance use is a leading cause of morbidity and mortality that is under-identified in primary care settings. Screening for substance use in primary care requires an efficient and accurate approach. Exploring methods to collect sensitive and accurate data about substance use and related problems is important to inform research practice and clinical care. Using RCT data comparing computerized and therapist delivered brief intervention for substance use problems, the present study had a unique opportunity to compare computerized anonymous and confidential surveys to a confidential, interviewer-administered assessment in a sample of N = 540 males and females at risk for heavy/problem …

Black Women And Body Image: Implications Of The Racialized Beauty Aesthetic, Rachel L. Boutte

Theses and Dissertations

Black women have the highest prevalence of overweight and obesity relative to any other demographic group in the United States, however current weight management interventions appear least effective for them. Although several hypotheses have been proposed to explain these outcomes, few studies have collected data to evaluate how well they fit the lived experiences of Black women. In particular, the potential roles of body image and body dissatisfaction in the development and maintenance of overweight and obesity in Black women are not well understood. Extant literature largely reports that Black women are inoculated from body dissatisfaction due to cultural factors, …

Design Hub: Activating Community By Design, Ed Williams

Theses and Dissertations

MOTIVATION

At the turn of the century, Robert Putnam (2000, 27) wrote “...a powerful tide bore Americans into ever deeper engagement in the life of their communities, but a few decades ago that tide reversed and we were overtaken by a treacherous rip current.” Putnam is describing a loss of “social capital” throughout American society. Research suggests that many of our contemporary issues are the result of a decline in “social capital,” or “community.”

This pervasive lack of community is thought to be detrimental to “educational performance, safe neighborhoods, equitable tax collection, democratic responsiveness, everyday honesty, and even our health …

Adverse Childhood Experiences In Children Presenting To Integrated Pediatric Primary Care, Irene A. Jacobs

Theses and Dissertations

The prevalence of adverse childhood experiences (ACEs) has created a significant public health concern in the United States. A vast body of literature examining adult populations has displayed a dose-response association between cumulative ACEs and chronic illnesses (Chapman et al., 2004; Felitti et al., 1998). ACEs research conducted with children and adolescents has indicated higher ACE scores associated with learning and behavioral problems (Burke et al., 2011), health risk behaviors (Garrido et al., 2018), and mental health challenges (Mackner et al., 1997). However, ACEs research and subsequent interventions have largely relied upon retrospective data retrieved from adults (Felitti et al., …

Competing Models Of Exposure To Community Violence Among Urban Youth: Dimensional Versus Person-Centered Approaches, Sarah K. Pittman

Theses and Dissertations

Exposure to community violence is prevalent among urban youth residing in neighborhoods with high rates of crime and violence. Although there is strong evidence suggesting that community violence exposure is associated with negative consequences on youth development, there are inconsistencies in theories and evidence regarding the nature of these associations. Methodological limitations of dimensional approaches to conceptualizing exposure, including the assumption that adolescents are similar in their frequency and patterns of exposure, likely contribute to the inconsistencies in findings of associations. Recently, person-centered methods have been used to elucidate associations between community violence exposure and consequences on adolescent development. However, …

Effects Of A Self-Advocacy Intervention On The Abilities Of College Students With Intellectual And Developmental Disabilities To Request Academic Accommodations, Katherine R. Brendli

Theses and Dissertations

Students with intellectual and developmental disabilities (IDD) are pursuing college at higher rates than ever before. However, many of these students experience barriers to success in college and need to self-advocate for their needs, such as requesting academic accommodations. This study examined the effects of a virtually delivered self-advocacy intervention package on the abilities of college students with IDD to request their academic accommodations. This is the first study to virtually implement a modified version of the Self-Advocacy and Conflict Resolution strategy with college students with IDD. Using a single-subject multiple-probe across participants design, this study was implemented with three …

Separate And Unequal: Latinx Access, Enrollment And Completion Of Ap Coursework In The State Of Virginia, Virginia Elizabeth Palencia

Theses and Dissertations

In response to the national problem of overrepresentation of Latinx students in general education classes, this study addresses Latinx access to Advanced Placement (AP) coursework, enrollment, and completion patterns in Virginia, a growing destination state for many Latinx families and students. Through a secondary data analysis of both the Civil Rights Data Collection (2015-6) and College Board data (2016), this quantitative study mapped patterns of disproportionality in AP access, enrollment, and completion for Latinx students, who comprise 13% of enrollment in Virginia public high schools. In addition, a case study of two diverse school districts provides evidence of segregation and …

An Online Mindfulness Training For Improved Eudaimonic Well-Being And Sleep Outcomes In Caregivers: A Preliminary Study, Tarah L. Raldiris

Theses and Dissertations

As the United States population continues to age, the number of older adults with dementia is projected to rise. Much of the care for those with dementia is provided by unpaid, informal caregivers who are typically family members. Unfortunately, these informal caregivers express significantly higher levels of negative psychological and physical health outcomes compared to non-caregivers. One potential pathway for improving caregiver outcomes may be through increased mindfulness. Using a two-week, online-based mindfulness training program and a structurally equivalent cognitive reappraisal training program, study aims were to: 1.) investigate the acceptability and feasibility of using an online intervention format for …

Characterizing Patterns Of Cannabis Use And Related Health Effects Among Young Adults Using Ecological Momentary Assessment, Alyssa Rudy

Theses and Dissertations

Introduction: Rapid changes in cannabis use policy and prevalence, particularly among young adults, and the lack of information regarding cannabis harms warrant investigation regarding the daily use patterns of cannabis users. Little is known regarding how variability in cannabis use frequency and administration method use patterns may be associated with differential acute cannabis-related health effects (i.e., subjective intoxication and respiratory symptoms). The purpose of the study was to characterize daily and weekly cannabis use patterns and associated cannabis-related intoxication and respiratory symptoms and test the interactions of cannabis use frequency and cannabis administration method use on cannabis-related intoxication and respiratory …

Differential Identification Of Hyperacusis And Misophonia: Implications Of Discrete Decreased Sound Tolerance (Dst) Condition Subtypes, Rachel E. Wallace

Theses and Dissertations

Hyperacusis and misophonia are two conditions of decreased sound tolerance (DST) studied in the psychological literature due to their association with psychological symptoms and mechanisms. DSTs are differentiated from normal sound sensitivity due to the reported impairment and distress individuals experience. Researchers suggest that DSTs are differentiated by types of sounds and emotional reactions elicited, such that hyperacusis is a fear and pain response to ordinary environmental sounds perceived as uncomfortably loud, and misophonia is an anger and disgust response to human-made sounds, but these distinctions, and associated characteristics, have not been empirically demonstrated. Undergraduate students (N = 1572) …

The Role Of Receptive Reasoning In The Development Of Intellectual Humility, Cathryn Richmond

Theses and Dissertations

Intellectual humility (IH) develops throughout childhood and adolescence and is critically important for effective learning, particularly with regard to science; however, the research examining the development of IH in children is quite limited. As such, this study utilized an exploratory, mixed methods, community-engaged research design with children ages three to 10 (n = 60; M_age = 5.98; 69.6% female) and their parents/guardians recruited from a public children’s museum.. As the construct of IH is intended to describe adult cognition, I operationalized the set of components that may lead to the development of IH in preschool children as Receptive …

Interpersonal Competency Configurations And The School Adjustment Of Early Adolescents With Disabilities: A Person-Centered Approach, Brittany I. Sterrett

Theses and Dissertations

The transition to middle school is a critical time in adolescence. The more complex school environment provides opportunities for growth and challenges for students with disabilities. Although special education strives to provide individualized supports to students with disabilities through data-based decision-making, the tools used to understand and meet the needs of these students are often unresponsive to the dynamic nature of development and student adjustment as they age. Grounded in developmental science, this study sought to create a data collection framework through a person-centered approach to inform the individualization process. Specifically, this study: 1) explored a decision process that allows …

A Longitudinal Test Of Mexican Teen Mothers’ Cultural Characteristics And Children’S Language Skills Via Mothers’ Language, Arlenis A. Santana

Theses and Dissertations

The current study includes 204 Mexican teen mothers and their children from a larger study who were interviewed when children were 3 years old (Wave 4; W4), 4 years old (W5), and 5 years old (W6). The current study is guided by the integrative model of developmental competencies (García Coll et al., 1996), which suggests that parents’ adaptive cultural characteristics and exchanges with their children inform children’s developmental competencies. Thus, the current study examined whether teen mothers’ adaptive cultural characteristics (i.e., familism values, language competency pressures, and involvement in Mexican culture and U.S. mainstream culture) at W4 informed mothers’ Spanish …

Dating Violence Victimization And Posttraumatic Stress Outcomes Among Urban Adolescents: The Moderating And Mediating Role Of Positive Outlook, Carine Leslie

Theses and Dissertations

Adolescent dating violence occurs far too frequently in early adolescence and is related to adverse mental health outcomes, including posttraumatic stress symptoms. One focus within this literature has been to determine and better understand how protective processes may function in influencing relations between risk factors and dating violence victimization. A protective factor that has not been explored in the dating literature is positive outlook. The current short-term longitudinal study investigated whether dating violence victimization at Time 1 predicted posttraumatic stress symptoms at Time 2 among African American middle school students and examine whether positive outlook moderated or mediated this relation. …

Making Implementation Last: Understanding The Sustainability Of An Evidence-Based Treatment, Carrie Beth Jackson

Graduate Theses, Dissertations, and Problem Reports (ETD)

Although advances have been made in facilitating the implementation of evidence-based treatments, little is known about the most effective way to sustain their use over long periods of time. Prior systematic reviews and research have suggested that organizational characteristics and training methods may be strategies that support sustainability, yet this has remained relatively unstudied in the field of behavioral health. The current study examined the sustainability of Parent-Child Interaction Therapy following a statewide implementation trial testing three training methods. Participants included 100 clinicians and 50 administrators from 50 organizations across Pennsylvania. Multi-level path analysis was utilized to examine the role …

Changing Seasons Of Resistance: Impacts Of Settler Colonialism And Climate Change In Indigenous Worlds, Elizabeth Jackson

Cal Poly Humboldt theses and projects

This paper looks at the relationship between neoliberal capitalism, genocide, the biopolitics of settler colonialism and the impacts of climate change on the cultures and traditional lifeways of Indigenous communities. It also explores Indigenous modes and methods of adaptation and resilience. Climate Change is almost certainly the most urgent social problem in the history of human life on planet Earth. Many Indigenous people are more vulnerable to the effects of climate change due to marginalization and their commitment to land-based practices. Using in depth interviews with Indigenous Peoples, primarily from the Pacific Northwest, and the analysis of existing literature, this …

The Effects Of Feral Cat Removal On Rat Abundance In An Insular, Tropical Ecosystem, Douglas A. Page

Cal Poly Humboldt theses and projects

The colonization by rats (Rattus spp.) and cats (Felis catus) on islands are known to contribute to the decline of native birds. On the island of Rota, Commonwealth of the Northern Mariana Islands, cats are being lethally removed to conserve two endangered bird species. Although cats are controlled to reduce impacts on birds, they can also prey heavily on sympatric rats. Of euthanized feral cats on Rota, 60% had ≥1 rat in the stomach. Predation by cats could be a mechanism of top-down control of rats. Removing feral cats may reduce the magnitude of that control, leading …

Collective Healing Within Queer Paradoxes: Deconstructing Emotional Abuse In Lgbtq2sia* Communities To Cultivate More Accountable And Compassionate Worlds, Alexia Siebuhr

Cal Poly Humboldt theses and projects

Emotional abuses within LGBTQ2SIA* communities are rarely acknowledged as existing or often normalized. Through care and anti-oppression works, transformative justice models such as community and self-accountability have helped carve out ways of addressing harm directly and breaking cycles of violence. The research in this thesis has been through mixed qualitative methodologies including semi-structured interviews and surveys. The participants' along with other authors, artists, activists and scholars’ narratives draws upon the experiences of emotional abuse lived within structural and social surveillance. The settler colonial state sanctioned projects have responded to harm by perpetuating violence upon those most marginalized. Deconstructing emotional abuse …

Comparisons Of Spatial Reasoning Abilities Of String And Non-String Professional Musicians, Baby Vivian L. Esenbock

Cal Poly Humboldt theses and projects

This study provides evidence to support the transferable benefits of musical training to enhance performance on cognitive tasks involving spatial reasoning abilities. Spatial reasoning is an important skill that is essential for success in science, technology, engineering, and mathematics (STEM) achievement. Previous research indicates that students involved with musical instrument training score higher on measures of spatial temporal abilities than students with no musical training. We hypothesized that the greatest development of spatial visualization will be found in string instrument musicians when compared to non-string musicians, because of the visualization required due to the design of these instruments. Two studies …

Perceptions Of Academic Achievement In A Community College Sample, Devon Burg

Cal Poly Humboldt theses and projects

Self-reported GPA is often used in academic achievement research when gathering GPA as a variable, though it is not always completely accurate. Previous studies have shown that actual GPA affects self-report as those with higher GPAs tend to be more accurate. Those with lower GPAs tend to inflate their self-reported GPA. Race has also been identified as a variable that affects self-reported GPA as White students tend to be more accurate than non-White students. Gender has had mixed outcomes with accuracy of self-reported GPA.

Previous research showing self-reported GPA to be a valid measure of GPA has used samples from …

Mand Training And Prompt Fading: Teaching Yes-No Manding, Jessica M. Kelly

Cal Poly Humboldt theses and projects

Language is a collection of verbal skills which allows the speaker to have some control over how others interact with them. Saying the words “yes” and “no” are fundamental language abilities; The words impact the speaker’s environment by communicating acceptance or rejection of stimuli and experiences. Caregivers, teachers, and friends may have to make choices for an individual who cannot respond to yes-no questions. This skill deficit deprives the individual of autonomy and can lead to challenging behaviors occurring in place of clear communication. Applied Behavior Analysis offers techniques to teach language skills such as saying “yes” and “no” in …

Constructing Commonmentalities: Toward Collaborative Governance, Knowledge And Subjectivity, Imil Ferrara

Cal Poly Humboldt theses and projects

Western society’s intractable social and environmental problems arise outside the bounds of classical liberal ideation, challenging the utilitarian rationality, decision-making faculty, and popular legitimacy of our liberal institutions. Through a qualitative analysis of three collaborative, community-based institutions, this study aims to identify and illuminate alternative conceptions and organizational relationships, which transcend liberal shortcomings and succeed precisely where liberal institutions have failed. It draws on Michel Foucault’s account of liberal governance, discourse and subject formation, but employs a complex-systems lens to move from critical deconstruction to intentional normative construction, from radical subjectivism to a collaborative pragmatic realism, and from the critique …

Relationship Of Parent Academic Socialization To Academic Success Among First Generation College Students, Aubrey Pellicano

Cal Poly Humboldt theses and projects

Research shows that First Generation College Students (FGCS) have lower rates of college degree attainment than their continuing generation peers. Many of these students face challenges navigating social, academic, financial, and administrative domains when working toward a post-secondary degree. Academic self-efficacy (ASE) is an important predictor of academic success in college. Research suggests that parents can influence ASE through parent academic socialization (PAS), which includes academic expectations set by the parents (PAE), parent academic advice (PAA), and parental attitudes about education (PEA). The current study sought to examine the influence of PAS on ASE in FGCS and its subsequent effect …
