Cognitive Differences In Parkinson’S Disease With Amyloid Positivity And Negativity, Kenya Luna

Electronic Theses, Projects, and Dissertations

In Parkinson’s Disease (PD), research has shifted to investigate how biomarkers commonly seen in Alzheimer’s Disease (AD), such as amyloid beta (AB), may be associated with cognitive functioning in PD. AB is considered a reliable biomarker for AD pathology, however in PD there is a lacking biomarker that can accurately reflect severity of cognitive impairment. AD research has shown an association between low AB and cognitive decline, but the data in PD has mixed results. Most studies that analyze cognitive decline and biomarkers do not use a cutoff level and the few that do have a threshold vary greatly in …

The purpose of this study was to investigate work-family identity and its role in experiences of work meaningfulness. Specifically, we utilized a cross-sectional survey design to examine the moderating effects of boundary management and FSSB in determining the relationship between identity and experiences of work meaningfulness. We tested our hypotheses using data collected from 196 employees who were categorized as either “work-identified” or …

Serotonin 1a Receptor Modulation On Behavioral Flexibility In Btbr And C57bl/6j Mice, Cassandra Cavazos

Electronic Theses, Projects, and Dissertations

Autism spectrum disorder (ASD) is a neurodevelopmental disorder that is characterized by a subset of symptoms known as restricted repetitive behaviors (RRBs). RRBs are categorized into both lower order and higher order RRBs, where the latter can be described as behavioral inflexibility. The BTBR T+ tf/J (BTBR) mouse strain has been an extensively used animal model that demonstrate the behavioral symptoms of these individuals, including inflexible behavior. Currently, there are few effective treatments for individuals with ASD that express RRBs. Past research has investigated treatments that target serotonin due its historic involvement in ASD. 8-OH-DPAT (8-hydroxy-2-(di-n-propylamine) tetralin) is a research …

The Cultural Mismatch Between Latinas' Interdependent Self-Concept And The Independent Culture Of Stem, Maria Guadalupe Velasco

Electronic Theses, Projects, and Dissertations

I assessed the role of self-concept fit, as outlined in the SAFE model (Schmader & Sedikides, 2018), in Latina college students’ feelings toward pursuing a STEM course. Research on the underrepresentation of certain social groups in STEM has mainly focused on the role of goal fit. More specifically, researchers have found that portraying STEM environments as affording communal goals promotes goal fit, which is related to positive outcomes like interest, belonging, and favorable ratings for STEM courses, careers, and lab positions (Belanger et al., 2017; Belanger et al., 2020; Diekman et al., 2011). Because Latinas are socialized within an interdependent …

The Role Of 5-Ht6 Receptor Activation In Learning Consolidation, Jasmine Alyssa Robinson

Electronic Theses, Projects, and Dissertations

The focus on serotonergic dysfunction as a contributor to cognitive deficits in disorders such as autism spectrum disorder, Alzheimer's disease, and schizophrenia drives researchers to investigate the functional impact of specific serotonin receptor types on executive functioning. By discerning the potential enhancement or impairment effects, this endeavor seeks to unravel the complex interplay between serotonin receptors and cognitive abilities. Specifically, within the three domains of learning, acquisition, consolidation, and retrieval, we find serotonergic modulation to be pivotal. Recent studies have highlighted the 5-HT6 receptor as a novel target for cognitive enhancement. However, the majority of the research investigates the effects …

Examining Construal Level Priming As A Potentional Intervention For Misinformation Sharing, Xiangyu Cui

Electronic Theses, Projects, and Dissertations

Misinformation has become increasingly difficult to combat in the digital age. The current study tested a model exploring the relationships between self-regulation, habitual social media use, construal level, and propagation of misinformation. Drawing from previous research, I hypothesized that individuals with higher self-regulation would exhibit lower susceptibility to misinformation sharing. I also hypothesized that habitual social media use mediates the relationship between self-regulation and misinformation sharing. In addition, I introduced construal level priming as an experimental intervention, where individuals primed with abstract construal levels may demonstrate more discerning information processing, thereby reducing the likelihood of misinformation sharing. Results from data …

Examining The Impact Of Transformational Leadership On Employee Development And Performance: The Role Of Inspiration And Trust, Kayla Pham

Electronic Theses, Projects, and Dissertations

Transformational leaders are known to encourage, motivate, and engage followers in ways that enhance organizational outcomes. Researchers like Bernard Bass expanded on transformational leadership after James V. Downton introduced the idea. Bernard Bass was critical since he found ways to measure the success of transformational leadership (Givens, 2008). The four major principles of the transformational leadership theory are idealized influence, inspirational motivation, intellectual stimulation, and individualized consideration (Bass, 1985). This study aims to determine whether transformational leaders increase employee development and performance through their ability to inspire and trust in their followers. Variables such as performance, employee development, inspiration, and …

Beyond Initial Engagement: Investigating Factors That Contribute To Continued Participation In Social Movements, Alejandro Garcia

Electronic Theses, Projects, and Dissertations

Historically, social movements have been important in addressing social issues and driving social change, particularly in challenging both systemic racism and structural inequalities faced by minority groups. However, these movements require sustained participation to be effective. While it is important to understand the psychological factors as to how and why one engages in social movements, few empirical studies have evaluated the psychological factors that influence ongoing participation in social movements. This study examines predictors of continued engagement in social movements among individuals who have participated in two or more in-person demonstrations. A sample of 305 participants involved in four different …

The Role Of Social Support And Emotional Regulation In Relationship With Adverse Childhood Experiences And Food Addiction, Negin Ghaffari

Electronic Theses, Projects, and Dissertations

Adverse childhood experiences (ACEs) are potentially traumatic experiences that occur before the age of 18 and can have long-standing impacts on mental and physical health. Individuals with high exposure to ACEs may be at increased risk for depression, substance use disorders, and cardiovascular disease (Hughes et al., 2017). Social support has been shown to play an essential role in reducing the likelihood of adverse outcomes, such as substance dependence following exposure to adverse experiences. Furthermore, emotional regulation difficulties have been shown to mediate the relationship between childhood trauma and food addiction. There has been little research on adverse events in …

The purpose of this study was to evaluate perceptions of social workers and social work students have the necessary skills, knowledge, and training to identify, and provide intervention for Commercially Sexually Exploited Children (CSEC). Data was collected from thirty-five participants. Findings were that there appears to be no significance between the level of skills, knowledge and training among social workers and social work students in their ability to provide intervention for commercially …

Impact Of Perinatal Escitalopram Exposure On Adolescent Behavior, Jessica Bezenah - Bottorff

Electronic Theses, Projects, and Dissertations

Escitalopram (EST), a selective serotonin reuptake inhibitor (SSRI), is an antidepressant frequently used during pregnancy, yet there is limited knowledge of its long-term effects on maternal use. Past studies suggest that maternal exposure may adversely affect the fetus, which may be due to the hyperserotonergic environment caused by the nature of SSRIs during early development. Modifications of the serotonergic system in offspring during certain critical periods of development may result in long-term behavioral and cognitive changes in adulthood. Further, recent human studies have demonstrated that prenatal exposure to SSRIs in humans may increase susceptibility to autism spectrum disorder (ASD) and …

Career Motivation As Mediator Between Cultural Self-Construal And Interest, Mengxuan Zhang

Electronic Theses, Projects, and Dissertations

Understanding the association between career motivations and interest-occupation congruence can help people with different cultural backgrounds make better career decisions. The goal of the study was to examine how cultural differences predicted interest congruence, and whether career motivation was a significant mediator in the prediction. I hypothesized that independent self-construal would be associated with internal career motivation most strongly (H1), while interdependent self-construal will be associated with interpersonal career motivation most strongly (H2). Additionally, internal career motivation would mediate the relationship between independent self-construal and interest congruence (H3), and whether internal career motivation mediated the relationship between interdependent self-construal and …

Examining A Relationship Between Sexual Satisfaction And Child Maltreatment, Amanda Titone

Electronic Theses, Projects, and Dissertations

Child maltreatment is prevalent despite extensive research informing interventions. While many risk factors have been identified, exploring additional determinants may improve existing methods or reveal better alternatives. This study’s basis was family systems theory, and it utilized the post-positivist paradigm to explore the topics of relationship fulfillment, sexual satisfaction, and parenting. Qualitative interviews with five heterosexual, cisgender parents born between 1971 and 1991 (average age 39-40) revealed four main themes: participants' childhood/parental relationships, history of abusive relationships, current sex life, and role balancing between relationships and parenting. Although limited by a small sample size and a specialized population (social work …

The Relationship Between Role Models, Socioeconomic Mobility Beliefs, And Academic Outcomes, Christian Koeu, Marisol Espinoza Garcia

Electronic Theses, Projects, and Dissertations

Objective: This study aims to provide insights into the relationships between role models, socioeconomic mobility beliefs and the education outcomes of students from low socioeconomic backgrounds. While previous studies highlight the positive influence of role models on academic and career aspirations, the specific relationship between role models and socioeconomic beliefs remains unexplored. Our study addresses this gap by examining whether the presence of role models relates with more optimistic socioeconomic beliefs and how these beliefs, in turn, affect academic outcomes (academic engagement, academic intentions, and grade point average [GPA]). Additionally, we investigate the influence of role model characteristics to …

Children and adolescents whose siblings die due to pediatric cancer are at an increased risk for several mental health issues and high risky behavior engagement. There is currently very little literature on the topic of a sibling’s grief despite its potentially critical and persisting consequences. Through qualitative research in analyzing art projects made by bereaved siblings, this is an exploratory study of how an art program may help bereaved or grieving children access their feelings using a non verbal modality of expression. The research study was conducted at a community-based non-profit organization which focuses on supporting families of children with …

Repeated Treatment With 5-Ht1a And 5-Ht1b Receptor Agonists: Evidence Of Tolerance And Behavioral Sensitization, Jordan Taylor

Electronic Theses, Projects, and Dissertations

Serotonin has been found to regulate several cognitive and physiological functions, and its role in depression and other neuropsychiatric disorders has been a focus of research. More specifically, a wealth of research regarding serotonin focuses on serotonergic medications in the treatment of neuropsychiatric disorders, such as depression and anxiety, and stimulates the 5-HT_1A and 5-HT_1B receptors. Within the last decade, there has been an increase in prescriptions of psychotropic medication for children, however, the efficacy and adverse effects of these drugs have not been evaluated in younger populations. While antidepressants reduce symptoms of depression in adults, they are …

Biomarkers Of Objective Criteria For Subtle Cognitive Decline In Parkinson’S Disease, Mary Ellen Garcia

Electronic Theses, Projects, and Dissertations

Mild cognitive impairment in Parkinson’s disease (PD-MCI) is the continuum from normal cognitive function to dementia. Recent studies suggest that objectively defined subtle cognitive decline (Obj-SCD), which uses non-traditional “process” neuropsychological scores, may be a better pathway to earlier detection of cognitive impairment. Obj-SCD has been defined as the stage where cognition is not impaired, but biomarkers are present or cognitive impairment is minimal but not sufficient to meet MCI or dementia criteria. We examined the longitudinal trajectories of neurodegenerative markers among individuals who are classified as cognitive normal (CN), Obj-SCD, and PD-MCI. Past literature has been inconsistent about the …

The Role Of Muslim Communities In Easing The Challenges For Young U.S. Muslim Immigrant Children’S School Outcomes, Ghada Kassir

This study investigates the experience of Muslim immigrants in the U.S. and its impact on their children’s school outcomes. Using the theoretical frameworks of segmented assimilation, acculturation, social identity theory, and critical race theory, post-9/11 Muslim immigrants and their elementary school children are the focus of this study. Specifically, this study examines the associations among the following constructs: Muslim identity, culture and traditions, community connectedness, and children's school outcomes. This study hypothesized that there is a negative correlation between Muslim …

Cerebrospinal Fluid Biomarkers Not Associated With Neurologic Compromise Among Mild Cognitively Impaired Reverters With Parkinson's Disease, Cameron Ryczek

Electronic Theses, Projects, and Dissertations

Parkinson's Disease (PD) is a neurodegenerative disease characterized by motor (e.g. tremors) and non-motor symptoms (e.g. cognitive impairment). PD patients' change in cognitive functioning can be observed using the following classifications: cognitively intact, mild cognitive impairment (MCI), or dementia (PDD). MCI has many subtypes, one of which is MCI reversion which is defined as those with MCI at one time point reverting to cognitively intact later. While there is limited research into the utility of MCI reversion and its relationship with cerebrospinal fluid (CSF) biomarkers in PD, this study will begin to elucidate this relationship. To this end, data from …

Helping Your Child Manage Anxiety: A Parent Education Workshop, Clarissa Aglaén Gallardo

Electronic Theses, Projects, and Dissertations

Anxiety has become one of the most common mental health disorders in young children, and it has been shown to have a significant impact on their development. Anxiety can make a child more susceptible to a number of negative effects, including a weakened immune system, developing “negative” habits such as nail biting, increased proneness to anger or crying, as well as difficulties in learning and retaining information. Conversely, when parents/caregivers can prevent or decrease anxiety in their children, children can better regulate their emotions, have more successful relationships, take more risks, and cope better with challenges. The purpose of this …

Grief, Depression, And Well-Being: The Role Of Social Support And Psychological Inflexibility, Ashley Wicochea

Electronic Theses, Projects, and Dissertations

Grief/bereavement is a normal emotional process that individuals experience upon the death of a loved one. Complicated grief or prolonged grief disorder results when grief becomes prolonged and associated with impairment in functioning (Howarth, 2011; Al-Gamal et al., 2018). Previous research has found a positive relationship between prolonged grief and depression. Moreover, research has found that the relationship between grief and depression was strongest under conditions of low peer support (Al-Gamal et al., 2018). Previous research on psychological inflexibility has found a positive relationship with grief and psychological distress, and a negative relationship with psychological well-being (Howell & Demuynck, 2021). …

Pathways Through Care Of Latinx Individuals Experiencing First-Episode Psychosis, Estevan Hernandez

Electronic Theses, Projects, and Dissertations

Many individuals experiencing first-episode psychosis (FEP) are unable to work or live independently due to the debilitating nature of their illness. Many individuals experiencing FEP fail to seek mental health treatment for their symptoms. The families of these individuals are often the first to notice early signs of psychosis and seek treatment for the individual (Bridges et al., 2012). there continues to be a high percentage of disengagement from mental health services which may, in turn, contribute to poorer outcomes across various areas in one’s life (Kreyenbuhl et al., 2009). There continues to be a high percentage of disengagement from …

One Of Us: Monoracial Latinx Perspectives Of Multiracial Latinx-White Individuals, Rosemary Rojas

Electronic Theses, Projects, and Dissertations

Little is known about bias against Multiracial individuals, but no research has specifically examined the experiences of Latinx-White Multiracial people and their exclusion from the Latinx community. Two experimental studies tested the effects of a target’s perceived Multiracial identity on Latinx participants’ beliefs and attitudes towards about Multiracial Latinx-White individuals. Utilizing social categorization theory, I hypothesized that Multiracial Latinx-Whites pose a threat to the distinctiveness of the Latinx community via perceived better social status and less discrimination. Specifically, Multiracial targets who appear more White than Latinx will be perceived by Monoracial Latinx participants to have higher social status, experience less …
