Phenotype Extraction: Estimation And Biometrical Genetic Analysis Of Individual Dynamics, Kevin L. Mckee

Theses and Dissertations

Within-person data can exhibit a virtually limitless variety of statistical patterns, but it can be difficult to distinguish meaningful features from statistical artifacts. Studies of complex traits have previously used genetic signals like twin-based heritability to distinguish between the two. This dissertation is a collection of studies applying state-space modeling to conceptualize and estimate novel phenotypic constructs for use in psychiatric research and further biometrical genetic analysis. The aims are to: (1) relate control theoretic concepts to health-related phenotypes; (2) design statistical models that formally define those phenotypes; (3) estimate individual phenotypic values from time series data; (4) consider hierarchical …

Predictors Of Mental Health Need And Treatment In Safety Net Primary Care, Kristen O'Loughlin

Theses and Dissertations

Many mental health (MH) needs go unidentified in primary care, and certain patients appear to be at higher risk of needs going unidentified and subsequently untreated. Little is known about patterns of detection and treatment in clinics with integrated mental health services. The purpose of this study was to characterize the prevalence of MH needs and evaluate patient characteristics as predictors of both the presence of a MH need and type of MH services received. Subjects were patients receiving care at two safety net primary care clinics with integrated mental health services (N=816; 52.7% Latinx, 15.9% African American), …

Associations Between Stress, Racial Discrimination, And Cytokine Levels In Black Americans, Takia Williams

Theses and Dissertations

Inflammation is a common pathophysiological pathway for a number of chronic diseases and is influenced by exposure to stress. Although there are racial disparities in health outcomes, relatively little is known about factors that may influence the inflammatory response in Black American individuals. This study examined whether racial discrimination and other forms of stress are associated with the balance of pro- and anti- inflammatory cytokines in Black American adults. Data from 22 participants were drawn from a larger study of Black American children (ages 5-12) and their primary caregivers drawn from low income neighborhoods in Richmond, Virginia. Caregivers reported demographics, …

The Effects Of Ingroup Threat On The Anchoring And Adjustment Heuristic, Mattie V. Hedgebeth

Theses and Dissertations

Since its introduction in 1974, the anchoring and adjustment heuristic has been a topic of interest within the field of decision making. Although much work has examined factors that affect the process of the anchoring and adjustment heuristic, very little has been studied about the self-processes that may influence how individuals anchor. More specifically, self and ingroup motivations have yet to be explored. This research sought to identify whether an individual’s magnitude of adjustment from an anchor can be affected by either an enhancement or threat of the individual’s ingroup. I hypothesized that ingroup enhancing information would induce a smaller …

What Happens When Cross-Sector Partnerships Are Mandated? Analyzing Trust Through A Transaction Cost Approach, Vanessa Hubbard Rastberger Dr

Theses and Dissertations

Cross-sector partnerships that combine the perspectives and needs of public, private, and nonprofit sectors have been used to address public policy challenges. Research has shown that trust and reputation among partners play an important role in the performance of partnerships. Trust has been positively associated with the reduction of transaction costs of partnerships, and therefore, this study used a Transaction Cost Economics (TCE) approach as the theoretical framework.

Some partnerships are volitional while others are the results of legal or other mandates. Does this volitional or non-volitional (mandated) status affect how collaboration is perceived? For instance, will collaboration and trust …

From The Margins To The Center: Legitimation Strategies From An Alt-Right Case Study, Lauren C. Garcia

Theses and Dissertations

Despite a growing interest in understanding Donald Trump’s election in 2016 as part of the historical trajectory of white racial identity politics, we do not know much about how ideas deemed “radical right” become mainstreamed. My study builds on extant research that implicates the emergence of the think tank industry by viewing one such right wing think tank as a racialized organization. My analysis focuses on the organizational strategies of the National Policy Institute (NPI). Google searches for NPI spiked in 2016 with their vocal support of Trump and visible organizing in D.C. Using Williams’ (2018) theoretical framework of organizational …

Profiles Of Adjustment Among Children In Institutional Care In Ghana: Predictors Of Positive Functioning, Anna W. Wright

Theses and Dissertations

Worldwide, approximately 2-8 million children reside in institutional care, which can lead to developmental setbacks. Given the need for institutional care persists, it is important to continue investigating which improvements can be made to provide optimal care. The current mixed-methods study included participants from Accra, Ghana. Study 1 involved cluster analyses to determine patterns of adjustment for 100 children in institutional care (CIC) (M age = 13.31 years, SD = 3.14; 40% female) and 100 children in families (CIF) (M age = 13.37 years, SD = 3.08; 40% female) across several domains. ANOVA was used to evaluate whether …

Exploring Whether Contextual Factors Relate To The Hoped-For And Feared Possible Selves Of Latinx Youth, Stephanie M. Romo

Theses and Dissertations

Youth’s hopes and fears for their future (i.e., hoped-for and feared possible selves) are related to their academic and health behavior outcomes. Much of the literature on possible selves focuses on African-American and European-American youth. In a sample of 132 Latinx youth, the present cross-sectional study utilized widely-used measures (i.e., Possible Selves Questionnaire, Beliefs about Education, Youth Risk Surveillance Survey) to identify the content and characteristics (e.g., strategies, balance) of their possible selves; investigate the relationship between contextual factors (e.g., sex, immigrant status) and possible selves; and, explore whether possible selves predicted youth’s beliefs about education and sexual risk behaviors. …

Orbiting Forward (Thoughts On The Nature Of Conflict - Sighs On The Struggles Of Change), Bushra A. Alsughayer

Theses and Dissertations

Today’s world is a wide open hyper-connected sphere where human societies worldwide exist in a complex crossroads of historical conditions, ideologies, and power structures. A pool of constant confrontations, minor or major, between the traditional and the progressive, the local and the international, the materialistic and the transcendent, the pragmatic and the idealistic, and countless layers of meaning. For an individual who exists in such an intense moment of history, it seems almost inescapable to be exposed to, affected by, or even involved in a major conflict. A situation that makes individuals always in a critical position where every role …

Legal Permanent Residents In The Us Labor Market: Occupational Mobility Of High-Skilled And Low-Skilled Immigrants, Larissa Ferreira Coelho

Theses and Dissertations

Despite the vast research concerning immigrants and occupational mobility, little is known if the patterns for high-skilled and low-skilled workers differ. In this project, I analyze the pre-to-post migration occupational mobility of legal permanent residents in the US by using occupation and migration histories from the New Immigrant Survey. I contrast the first occupation in the US to the last occupation abroad using descriptive statistics, hypothesis testing, and multinomial logistic regression models. Findings show different patterns of occupational mobility for low-skilled and high-skilled workers. High-skilled immigrants were less likely to experience downward occupational mobility than their low-skilled counterparts. The high-skilled …

Cultural Placemaking In Washington’S U Street Corridor: A Catch 22, Maya Coleman

Theses and Dissertations

Placemaking is a tool largely employed in gentrifying cities to create social and cultural character in space. However, the informal placemaking that naturally occurs in communities and public space is often left out of the placemaking planning process. Informal placemaking that existed in space before and after gentrification, often by the working class, may find itself the target of policing from class and racial power structures that new residents now making up the majority bring. Alongside gentrification is its use of placemaking as branding for space, which Black American culture is increasingly being operationalized. Using Washington D.C.’s U Street Corridor …

Come And Get Your Capital, Sis: The Use Of Twitter To Compensate For Gendered And Racialized Job Networks Among Creatives, Sasha A. Pierre- Louis

Theses and Dissertations

Due to racialized and gendered exclusion and discrimination, Black and women jobseekers do not have the same access to social ties in the labor market as white men. A number of Black Twitter users, particularly Black women, have cultivated networks on Twitter and elsewhere as explicit alternatives to this old boys’ network. This study aimed to understand how workers in creative industries—which tend to be more reliant on referrals—use Twitter to expand their social networks and gain access to job opportunities, and how their use of Twitter differed by race and gender. Four hashtags were queried through the Twitter application …

A Meta-Analysis Investigating The Correlation Between Treatment Integrity And Youth Client Outcomes, Ruben G. Martinez

Theses and Dissertations

Objective: The relation between treatment integrity and youth client outcomes in psychosocial treatment research has implications for therapist training, study design, and study interpretation. Despite work done in this area, this relation remains unclear. The aim of the current study was to meta-analyze and describe characteristics of investigations of integrity and outcome in youth.

Method and Analytic Plan: A total of N = 30 studies were identified. Conceptual and methodological factors were coded. Pearson’s r represented the magnitude of the integrity-outcome correlation. Robust variance estimation was used to account for dependency of within-study effect sizes. Two models were run with …

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., …

A Phenomenological Study Of Nonbinary Resilience And Mental Health, Calvin J. Hall Iii

Theses and Dissertations

Nonbinary individuals, or those who do not exclusively identify with a male or female gender, have gained increasing recognition and representation within the past ten years. Despite these steps forward, nonbinary individuals still experience higher rates of sexual assault, police brutality/harassment, job-related discrimination, and erasure when compared to binary transgender individuals, or gender-diverse individuals who exclusively identify as male or female. These disparities in violence, discriminatory practices, and erasure have been linked to exceptionally high rates of depression and anxiety in nonbinary people within the U.S. Thus, efforts to improve nonbinary mental health are critically needed. Previous research finds that …

Social Learning Theory And Digital Piracy: Explaining Uploading Behaviors Of Digital Pirates, Cydney J. Lowenstein

Theses and Dissertations

Digital piracy has received significant attention in criminological research but almost no studies have explored illegal uploading and how it may differ from illegal downloading. It is important to examine what theories can explain illegal uploading behaviors and their related factors to develop more effective policies to address digital piracy. This dissertation examined whether Akers’ (1998) social learning theory could explain engagement in digital piracy, both illegal downloading and uploading behavior. Additionally, this research examined the relationship between reciprocity and digital piracy. Questionnaires were administered to 398 university students and 315 visitors to several online communities using a combination of …

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 …

Comorbidity In Context: Identifying Patterns Of Depressive And Anxiety Symptoms In African American Early Adolescents, Kathryn Behrhorst

Theses and Dissertations

Depression and anxiety during adolescence includes symptoms of irritability, sleeplessness, feelings of guilt or worthlessness, worry, avoidance, and/or restlessness. Anxiety and depressive symptoms are often comorbid and are associated with impairments across academic, social, and emotional areas of functioning. No studies to date have examined patterns of depressive and anxiety symptoms together for African American adolescents using person-centered analyses. The current study examined patterns of symptoms and domains of anxiety and depression during early adolescence using latent profile analyses (LPA). A sample of 196 African American early adolescents in grades six through eight (M_age = 12.6; 50% female) were …

Credit The Parents? The Impact Of Racial Socialization On African American Students’ Stress-Related Coping And College Adjustment, Briana Bouldin

Theses and Dissertations

Many new stressors emerge in college and have a significant impact on college adjustment. However, little is known about common stressors, their causes, and impact on college adjustment for students attending Historically Black Colleges and Universities (HBCUs). This project investigated the extent to which different college stressors impact sleep-related college adjustment, and whether racial socialization and emotion regulation strategies serve as coping strategies that moderate this relationship for HBCU students. The theoretical framework for the study was an adapted version of the Integrative Conceptual Model of Adaptive Socialization (ICMAS; Dunbar et al., 2017). Data were collected via an online survey …

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 Second Shift.” Female Police Officers And The Struggle Of Work/Life Balance And Promotion, Ashlyn Decruise-Fortune

Theses and Dissertations

This study examined how women in law enforcement maintained a work-life balance with responsibilities such as motherhood, domestic responsibility and other care-taker roles. While there has been some research conducted on female police officers, much of the literature was outdated. Further, many of these studies focused on women’s performance and competence as police officers, and the associated burnout rate of female police officers. Very few studies examined the gender gaps in supervisory positions in relation to the Law Enforcement field within the United States, as well as the continued underrepresentation of women in Law Enforcement. Additionally, previous literature did not …

It’S Funny Because It’S True: The Transmission Of Explicit And Implicit Racism In Internet Memes, Tabitha Fairchild

Theses and Dissertations

Video games are traditionally seen as the domain of heteronormative white males. The purpose of this study is to explore how racism is transmitted and reproduced within digital communities, and how humor is being used to frame racist discourse in virtual spaces. Digitally, internet memes are widely used rhetorical vehicles, reaching large and broad audiences. The roles these artifacts play in the reproduction and transmission of racist ideology is often obfuscated by the perception that internet memes are "just jokes." This study analyzes internet memes collected from 16 months of communication between members of Discord servers that self-identify as communities …

Predators And Principles: Think Tank Influence, Media Visibility, And Political Partisanship, Timothy Beryl Bland

Theses and Dissertations

By some measures, the major U.S. political parties have become more extreme in their political positions in recent decades, and scholars have raised concerns about whether the policy expertise provided by today’s think tanks has become similarly partisan and polarized. Furthermore, there is a perception that certain overtly partisan and highly visible think tanks wield considerable and growing influence over the policy platforms of the major U.S. parties, using their media presence to shape public and policymaker views of particular issues. Using publicly accessible tax, media, and congressional data, my proposed study assesses the extent to which media visibility and …

Why We Use A New Currency: The Role Of Trust And Control In Explaining The Perception And Usage Of Bitcoin, Joseph B. Walton

Theses and Dissertations

Social media, e-commerce, global peer-to-peer technologies, and the near ubiquity of computers and smartphones allow people to interact, trust, and exchange value across traditional socio-economic control boundaries and over significant distances. Since the creation in 2008 of a new cryptographic currency system called Bitcoin, a financial technology market sector of about 250 billion USD has rapidly emerged, raising questions about the nature of currency in society and whether new types of non-national money are warranted and viable. This debate has pitted heterodox economic interests against orthodox economic interests while it has rekindled interest in theories that view money as a …

Psychological Effects Of Reading: The Role Of Nostalgia In Re-Reading Favorite Books, Margaret A. Kneuer

Theses and Dissertations

There are many positive outcomes from feeling nostalgic, including reductions in loneliness and greater meaning and social connectedness. My primary research goal was to investigate whether I could trigger feelings of nostalgia from re-reading an old favorite book, and whether this elicited nostalgia would increase feelings of connectedness and meaning in life and reduce loneliness. I designed a two-study package (one correlational study and one experiment) to assess re-reading novels. Trait nostalgia was positively associated with enjoyment of re-reading books (Study 1). Re-reading a favorite novel, relative to reading a new novel or a set of newspaper articles, elicited nostalgia. …

The Intersection Of Social Stress, Mental Well-Being, And Sexual Health Among Black Women In Emerging Adulthood, Brandi Galloway

Theses and Dissertations

With an estimated 37,000 new HIV infections each year, HIV continues to be a major public health concern. HIV affects some populations more than others. Young Black women, in particular, are disproportionately affected by HIV. While being a woman does not typically increase a person’s HIV risk, being Black and being a woman does.

Data indicate that individual-level factors do not fully address the differences in HIV and STIs between Black emerging adult women and their White counterparts. Thus, it is critical to better understand contextual factors such as social stress and mental-wellbeing which might better account for these disparities. …

State Economic Development: Analyzing The Moderating Effects Of Business Climate On Economic Growth, Sean A. Brazier

Theses and Dissertations

States across the country focus intensely on creating jobs, catalyzing capital investment, and stimulating economic output. They pursue different strategies, mixing and matching a variety of tactics in the pursuit of their economic objectives. While scholars have studied the relationship between economic development tactics and economic growth or business climate and economic growth, none to my knowledge have studied the impact of economic development efforts on economic outcomes while accounting for a state’s business climate.

I found economic development spending to be negatively associated with employment growth (other measures, real gross state product and per capita income growth, were not …

Transcriptomic Profiling Of Postmortem Prefrontal Cortex And Nucleus Accumbens From Chronic Alcohol Abusers., Eric S. Vornholt

Theses and Dissertations

Alcohol use disorder (AUD) is a debilitating psychiatric illness that develops from a combination of genetic and environmental factors. While it is well documented that AUD is heritable, the shift from recreational alcohol use to abuse/dependence is poorly understood. In this dissertation, using postmortem brain tissue from individuals with alcohol dependence (AD), we profiled the genome-wide expression of circular RNA (circRNA), microRNA (miRNA), and messenger RNA (mRNA) to better understand the impact of gene expression on the development of AUD. To achieve this, we performed two independent studies that explore transcriptome differences between AD cases and controls. The first of …

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 …
