Aerobic Exercise Alters Opioid Receptors Following Chronic Alcohol Exposure, James N. Brundage

Theses and Dissertations

Opioid receptors have been a target of pharmacological manipulation in alcohol use disorder (AUD) recovery protocols for many years. Aerobic exercise, a common adjunct in AUD recovery, is known to modulate opioid receptors (ORs) both during both acute and long term exposure. The three subtypes of ORs: mu (MOR), delta (DOR), and kappa (KOR) are all expressed on neurons in the mesocorticolimbic circuitry. Kappa-opioid receptors are expressed directly on dopamine (DA) neuron terminals in the nucleus accumbens (NAc). Mu and Delta ORs are expressed on cholinergic interneurons (CINs) and GABA neurons in the NAc. In alcohol dependent rodents, KORs are …

Men, Women And Witchcraft: The Feminist Reclamation Of The Witch In The Modern Horror Film, Brian Joseph Hadsell

Theses and Dissertations

The witch as a figure possesses a powerful and enduring legacy in Euro-American culture; she is both a victim of patriarchal persecution and the natural enemy of a deeply-gendered society. Recent horror films that employ the witch, however, have generally done so in the form of reclaimed feminist icon: a violently retributive figure avenging the wrongs done to women both past and present. The purpose of this research is to provide insight about our acutely gendered society and culture in the times during and preceding the #MeToo movement through a semiological analysis of three recent horror films that center on …

Relationship Of Posterior Intracranial Venous Structures In Homo Sapiens And Handedness, Brianne Finley

Theses and Dissertations

The transverse sinus spans the endocranial surface of the occipital bone and ultimately transmits deoxygenated blood to the sigmoid sinus and jugular vein en route to the heart. This paired sinus tends to be more defined on either the left or right side in human crania. Left and right dominance, or the use of one side of the body more than the other, leaves traces on the human skeleton. Methods to determine handedness upon examination of various elements of the human skeleton mostly focus on the use of the extremities, while little research exists examining the skull for evidence of …

Three Essays On Ceo Activism, Strategic Choices And Firm Performance, Keshab Acharya

Theses and Dissertations

There is a longstanding societal expectation that business leaders refrain from involving in social and political issues and primarily focus on managing their firms. In recent years, however, there is a growing trend of CEOs taking a stance on controversial sociopolitical issues that are not directly related to their company’s core business. This dissertation consists of three essays focusing on this phenomenon of CEO activism.

In my first essay, given that CEO activism represents a nascent phenomenon, I explore the conceptualization of CEO activism. Additionally, I propose three main motives behind CEO activism: intrinsic, instrumental, and stakeholder-focused. In my second …

Seeking A Perfect Match: The Effect Of Spousal Capital On Performance Of Family Firms, Xi Yang

Theses and Dissertations

The research about family business has received increasing attention. However, the research that focuses on the effect of owner-managers marriage on family firm performance is scarce. In this study, I argue that the family business manager's spouse can affect firm performance through firm-level and individual-level channels. First, I propose that a family business's firm performance is influenced by owner-managers marriage in terms of spousal human, social, and financial capital based on a family capital topology—a firm-level lens. I build a conceptual model of spousal capital in a family business and develop hypotheses. Further, by integrating the complementary needs theory of …

Embryonic Exposure To The Synthetic-Progesterone Levonorgestrel (Lng) Results In Hyperactive Behavior In Zebrafish (Danio Rerio), Austin D. Fuentes

Theses and Dissertations

Exposure to endocrine-disrupting chemicals has been associated with an increased risk of anxiety-like behavior at various life stages. Levonorgestrel (LNG), a synthetic contraceptive, could potentially alter steroidal regulated brain development based on the findings of this thesis. In-silico measurements were used for comparing LNG, which had been found in surface water, to chemical databases to predict the bioavailability, half-life, and estrogen binding potential. Zebrafish (Danio rerio) for illuminating the effects of LNG exposure during early zebrafish embryonic development, similar to fetal development, on behavior was investigated. Our data suggests exposure in a dose-dependent manner of LNG can potentially …

An Exploration Of Mental Contrasting And Social Networks Of English Language Learners, Adam T. Pinkston

Theses and Dissertations

This study focuses on how applying MCII, a wish-fulfillment and goal-setting method researched by Gabriele Oettingen, benefits the quantity and quality of English language learners' (ELLs) social networks while participating in a study abroad program in the United States. This is done by instructing participants in the use of MCII, giving them weekly reminders on that instruction and the goals they set, and by measuring change from beginning to end. Analyzing the social networks of 36 English language learners at an intensive English program (IEP) after 14 weeks of instruction shows that the ELLs displayed growth in the number of …

Representation Of U.S. Minority Groups In The Marriage And Family Therapy Literature Over An 18-Year Period: A Content Analysis, Kensington Osmond

Theses and Dissertations

Research relevant to the unique needs and experiences of racial/ethnic/cultural (REC) minority groups in social science literature is essential to the work of policymakers and clinical practitioners. However, the social sciences have traditionally failed to publish a sufficient number of articles that address these needs and experiences or even adequately report the racial and ethnic makeup of their samples. The purpose of this study is to provide an updated look at Marriage and Family Therapy (MFT) literature and how often sample participants’ ethnicity is reported, how frequently studies focus on ethnic issues or specific REC minority groups, which REC minority …

Heterogenity In Brain Injury: An Investigation Of The Efficacy Of Qualitative Comparative Analysis In Diffusion Tensor Imaging, Cooper Benton Hodges

Theses and Dissertations

Traumatic brain injury (TBI) and its associated neural and cognitive sequelae are of increasing interest in military populations. Blast-related TBI is becoming more commonplace in military Service Members and Veterans since Operation Iraqi Freedom/Operation Enduring Freedom/Operation New Dawn and their following conflicts. It is currently unclear whether blast-related injuries cause unique neural and cognitive deficits. The present investigation, in Study 1, aims to investigate the differences in blast-related and non-blast related TBI using traditional statistical techniques. In Study 2, this study will demonstrate the use of Qualitative Comparative Analysis (QCA) in diffusion tensor imaging data. QCA is a relatively new …

Childhood Trauma And Attachment Theory: Estimating A Growth Curve Relationship Between Adverse Childhood Experiences And The Therapeutic Alliance, Connor C. Barham

Theses and Dissertations

The therapeutic alliance is a core element of successful treatment in therapy. Recent literature has explored variables that predict the alliance at various time points during therapy, but few studies have explored how the alliance develops over time and the factors that influence its rate of change. The current study addresses these questions by estimating latent growth-curve models to analyze how male and female partners' alliance scores develop over time and how adverse childhood experiences (ACEs) impact the development of the alliance during the first six sessions of therapy. Results from these analyses show that neither men nor women's ACEs …

A Fmri Of Fear Conditioning And Auditory Looming In Autism Spectrum Disorder, David Nicholas Top Jr.

Theses and Dissertations

Many autistic adults experience debilitating anxiety that interferes with their daily functioning. Atypical sensory processing and intolerance of uncertainty are cognitive processes linked to atypical limbic system functioning and impaired fear conditioning as potential mediators of anxiety in autism. A previous fear conditioning study using fMRI found atypical amygdala functioning in autism when the threat stimulus was only partially reinforced. The first aim of this dissertation is a multimethod examination of brain and psychophysiological response in autistic and in neurotypical adults during a fear conditioning/extinction task with the threat stimulus reinforced 100% percent of the time. We were also interested …

Be Good For Goodness' Sake: Parenting Practices That Promote Value-Congruent Behavior During Adolescence, Ryan David Mclean

Theses and Dissertations

Research indicates that adolescence is an especially crucial time for developing habits of values congruent behavior that will persist throughout the lifespan. Past research has suggested that parents may play an important role in socializing their children, however few studies have looked at the mechanism through which this socialization occurs. The current study explored associations between different types of proactive and reactive parenting and value congruent behavior using nationally representative data from across three years during adolescence. Additionally, the current study attempted to further explain these associations through the mechanism of extrinsic and intrinsic values regulation. The current sample included …

At Ages 1-2, Will Tv Impact If I Help You? Prosocial Media, Joint Media Engagement, And Infant Prosocial Development During The Second Year, Sara Catherine Brown

Theses and Dissertations

Prosocial behavior typically emerges during an infant's second year. Because it is posited to be continuous from infancy to adulthood, and past research has identified numerous positive outcomes associated with prosocial behavior, it is important to understand the mechanisms involved in early prosocial behavior, such as prosocial media. Past research has examined the relation between prosocial media and prosocial behavior in preschool children, but no studies have explored this association with infants. The current study includes 60 infants and their primary caregivers. Data about media use, parent-infant media interactions, and infant prosocial helping was collected through survey and observational measures. …

Domestic Bliss, Or Technological Diss? Problematic Media Use, Attachment, And Relationship Outcomes, Mccall A. Booth

Theses and Dissertations

The purpose of this study was to examine how problematic media use (technoference, internet gaming disorder symptoms, and pornography use) predicted later partner relationship outcomes, operating through the mediator of attachment behaviors. Participants (N = 1039) were from Waves II–IV of the Couple Relationships and Transition Experiences (CREATE) study, a nationally representative quantitative study on marriage relationships across the United States. Both spouses completed surveys reporting problematic media use, attachment behaviors, and relationship outcomes at three separate time points each spaced a year apart. In order to test the hypotheses, three longitudinal actor-partner interdependence models with indirect paths were estimated, …

The Role Of Microfinance Workers In Financialization: Negotiating The Meaning Of Development In China, Xue Ma

Theses and Dissertations

Microfinance is an attempt to alleviate poverty through offering collateral-free small loans to poor borrowers, especially women in developing countries or rural areas. Though it is indeed an actual economic activity, usually engaged in through some type of bank, there is much that is informal and context-bound in these transactions, making microfinance a kind of “social business.” While the impact of microfinance on women borrowers has been discussed many times, only a few studies have looked at the significance of the other members of the interaction: the microfinance workers, who are instrumental intermediaries between the women-borrowers and the microfinance institutions …

Online Dialogue In Response To Disclosures Of Intimate Partner Violence, Bria Nicole Davies

Theses and Dissertations

Intimate partner violence (IPV) impacts the lives of millions of individuals, devastating survivors, and damaging families. Many survivors are unsure of how to get help, and many have limited access to resources. In recent years, those affected by IPV have turned online for answers and support, including forums such as Reddit, to anonymously disclose their experiences. This study examined the dialogue online between survivors of violence and those who respond to their posts on Reddit. The aim is to better understand the kinds of conversations and responses that are occurring in online communities discussing IPV. Analysis of the domestic violence …

Managing Citizen Engagement: Local Leader Perspectives From A Midwestern Small City, Isabella B. Green

Theses and Dissertations

Small cities, with their mix of urban capacity and small-town charm, are a promising environment for interactive and inclusive citizen engagement. However, small cities have received very limited attention by sociological and planning literature, and even less attention has been paid to the leaders of small city communities. This study contributes to this gap through an analysis of the dynamics of participation between small city leaders and their constituents from the leaders’ perspective. Studying up through interviews with planners and officials of a midwestern small city, this study examines how small city leaders pursue citizen engagement while managing the bureaucratic …

As Good As Woke? : Mutuality And Third Spaces In A Guatemalan Volunteer Tourism Organization, Hannah Gdalman

Theses and Dissertations

It is estimated that as many as 10 million individuals participate in international volunteering projects annually (McGehee, 2014). Since its rise in the late nineties and early aughts, voluntourism has drawn the attention of academic and non-academic audiences alike, who have warned of the perils of exploitation, commodification, and white saviorism. This study conducts an issue-focused analysis to examine the extent to which the voluntourism experience has evolved into one of mutuality rather than cultural hegemony. Sixteen semi-structured interviews and participant observation were conducted at a longstanding Guatemalan voluntourism site. Wearing & Wearing’s (2006) Third Space interactive cultural tourism framework …

Social Withdrawal Associated With Regret And Fulfillment In Three Long-Term Care Facilities, Melanie Mei Yukie Serrao

Theses and Dissertations

The study of social withdrawal continues to grow among younger samples, including childhood, adolescence, and emerging adulthood. Little research has addressed socially withdrawn older adults, despite the various losses, declines, and changes experienced by those in later life and their known benefits resulting from social interactions. Shy, avoidant, or unsocial individuals at younger ages may withdraw and possibly miss out on important opportunities; as a result, when they are grown, these same socially withdrawn individuals may experience greater regret and lower fulfillment in later life. Further, socially withdrawn older adults residing in long-term care (LTC) facilities may have more time …

Status Of Social Studies Within One Georgia School District, Tonya Fields Pinckley

Theses and Dissertations

The purpose of this causal-comparative research was to examine whether differences exist between the time allotted for delivering content, the time allotted for lesson planning, the time allotted for student assessment, instructional perceptions regarding mandated testing, perceptions regarding pedagogical content knowledge (PCK), level of ease of planning, level of understanding of Georgia Standards of Excellence (GSE), level of understanding of the teaching-assessment cycle, and usage of the system provided pacing guides within public elementary schools in one Georgia school district across the content areas of ELA/reading, mathematics, science, and social studies. The research also examined the differences in instructional strategies …

Unraveling The Temporal Aspects Of Victimization: The Reciprocal, Additive, And Cumulative Effects Of Direct/Vicarious Victimization On Crime, Yeoju Park

Theses and Dissertations

The current study aims to assess the continuous impact of direct/vicarious victimization on subsequent victimization and delinquency/crime across waves using an incorporated model of Agnew’s general strain theory and the lifestyle/routine activities perspective. This study also aims to assess the additive and cumulative impact of dual victimization (i.e., exposure to direct and vicarious victimization) on offending. A cross-lagged model is conducted to examine the impacts of direct victimization, vicarious victimization, and delinquency/crime at an early point in time on these variables at later points in time using three waves from the Pathways to Desistance Study. Negative binomial regression models and …

Campbell’S Chicken Noodle Soup™ And Saltine Crackers: A Milpero’S Autoethnographic Study Of Struggle And Success In Life And In Education, Ernesto Cantu

Theses and Dissertations

The state of Texas has close to 3,000 colonias, with most of them found along the Texas/Mexico border (“Colonias in Texas,” n.d.) and the most citizens of any state living in colonias. I grew up in a colonia in South Texas called Las Milpas, located in Pharr, Texas. Colonia children are often stigmatized and marginalized. This autoethnographic study is a look into my life as an educator and the social and cultural factors that have contributed to my survival and success. As a child, I lost both my mother and father. I was fortunate that my oldest …

A Legacy Preserved: A Comparison Of The Careers And Recordings Of Stanley Drucker And Karl Leister, Peter M. Geldrich

Theses and Dissertations

Today’s musician has an unprecedented amount of recordings through which they can influence their tonal concept, guide their phasing, and instill appropriate musical style. However, this abundance of recordings is both a treasure trove and a labyrinth in which one can lose their way without proper background on the recording artist. This context is necessary to determine the recordings in which a particular artist is most adept, and what stylistic lessons the artist best imparts. This document provides a comprehensive study of the careers and recordings of two of the most important clarinetists of the twentieth-century; Stanley Drucker and Karl …

Theses and Dissertations

This action research project, based on 15 days of study, examined the impact of blended learning on student engagement and achievement in a high school Reading Seminar classroom. This action research study answered three research questions: 1) What impact do blended learning strategies have on student motivation in a Reading Seminar elective course classroom? 2) How does the implementation of blended learning strategies in a Reading Seminar elective course affect student writing skills? 3) How does the implementation of blended learning strategies in a Reading Seminar elective course affect student reading skills? The participants included 13 high school freshmen in …

The Deconstruction Of Patriarchal War Narratives In Svetlana Alexievich’S The Unwomanly Face Of War, Liubov Kartashova

Theses and Dissertations

This thesis examines how the Soviet construction of womanhood resulted first in females’ active participation in World War II and then in the silencing of women’s war experiences by fabricating a reality in which women’s trauma did not exist. Such a deprivation of women’s agency led to female soldiers’ confusion of identity, experience of shame and consequential self-censorship. In The Unwomanly Face of War (У войны не женское лицо, 1985), Svetlana Alexievich acknowledges these neglected experiences and traumas, and creates a space in which women’s stories have a right to exist. Applying Jean Elshtain’s theory on the lack of attention …

Promoting Critical Consciousness: The Role Of Positive Youth Development Programming, Mackenzie Jaclyn Hart

Theses and Dissertations

This study examined the role of positive youth development programming and individual-level characteristics in promoting critical reflection (CR) in youth and adolescent participants. CR refers to the analytical component of critical consciousness (CC), or the exercise of challenging institutional practices that systemically marginalize or oppress certain subgroups. Survey and interview data were analyzed from at-risk high school students (N=250) participating in an after-school program across six sites in urban areas in the United States. Multiple regression models were used to predict the development of CR, and interviews were examined to look for themes related to quantitative findings. Results support that …

Immigrant Belonging In Belgium: Laws, Localities, And Living Together, Samuel P. Nielson

Theses and Dissertations

Nationalism is rising in Europe and the world. Much of it responds to massive migration, with nationalistic Europeans vocalizing their belief that immigrants do not “belong” in their countries. Many states respond to this influx of people and rising antiimmigrant sentiment by creating laws demanding immigrant “integration.” Yet a clear understanding of what defines “integration” remains elusive. So too does an understanding of how laws aimed at immigrant integration influence relationships between immigrants and local citizens, institutions, and spaces. This research addresses both of these points in Belgium, a politically and culturally fractured country that serves as a microcosm of …

Teacher Beliefs In Sex-Specific Neuromyths And Gender-Specific Instructional Strategies: Prevalence, Predictors, And Implications, Marriah Schwallier

Theses and Dissertations

Neuromyths are misconceptions or overgeneralizations about brain research and its relevance to education. A number of recent studies have demonstrated that teachers endorse neuromyths at high rates, but none have examined neuromyths related to sex-specific learning differences. This study is the first to create and utilize a neuromyth inventory designed to measure misconceptions about sex learning differences. The overarching goal of the study was to determine the prevalence and predictors of both sex-specific neuromyths and gender-specific instructional strategies. The study was conducted in three large South Carolina school districts that offered single-gender classes at some point between 2007–2016. An electronic …

Bifurcated Elementary Sister-Schools: Do They Affect Student Growth During Transition Years?, Victoria Gelbert

Theses and Dissertations

The purpose of this study was to determine whether students who attend a sister-school modeled elementary school experience a negatively disproportionate amount of academic growth the year students transition from the primary school to the elementary school in third grade. This study looked at two different elementary grade span configurations, the traditional PreK–5 model and the 3–5 sister-school model, to determine if there is a difference between third grade student academic growth in different grade configurations. Four sample schools agreed to participate in the study and were paired based on their grade span configuration and demographics. The sample schools provided …

Semiparametric Regression Analysis Of Survival Data And Panel Count Data, Lu Wang

Theses and Dissertations

Both censored survival data and panel count data arise commonly in real-life studies in many fields such as epidemiology, social science, and medical research. In these studies, subjects are usually examined multiple times at periodical or irregular follow-up examinations. Censored data are studied when the exact failure times of the events are of interest but not all of these exact times are directly observed. Some of the failure times of event of interest are only known to fall within some intervals formed by the observation times. Panel count data are under investigation when the exact times of the recurrent events …
