Case Study: Exploring Inservice Teachers’ Perceptions And Experiences Of The Effectiveness Of Gifted Preparation And Training Programs In Saudi Arabia, Khlood Khaled Alshareef

Graduate Theses and Dissertations

In Saudi Arabia, the teaching of gifted and talented students is relatively new, and research that describes the quality and effectiveness of teachers' gifted preparation programs and the training sessions they receive remain rather limited and inconsistent. Purpose: This dissertation focuses on understanding the perceptions and experiences of in-service teachers regarding gifted-focused preparation and training programs in the country. Research Design: Data were collected through observation and semi-structured interviews with teachers of gifted and talented students in the country. Findings: Analysis of the data revealed six themes related to teachers’ perceptions and experiences of preparation and training programs in Saudi …

The Effects Of Physical Function And Genetics On Cognition And Blood Biomarkers In Individuals At-Risk For Alzheimer’S Disease And Related Dementias, Joshua Louis Gills

Graduate Theses and Dissertations

Alzheimer’s disease and related dementia (ADRD) rates are expected to triple by the year 2050. Early detection and specific mitigation efforts are warranted to blunt the alarming rate. Physical function (PF) declines with age, but higher physical function is associated with better cognitive functioning in middle-to- older age individuals. Moreover, greater physical activity (PA) is associated with better global cognition; however, Apoliporotein e4 carriers may not gain the same benefits with exercise. Additionally, plasma phosphorylated tau 217 (p-tau217) has been identified as a novel diagnostic ADRD biomarker which needs further research to examine associations with risk factors. Therefore, the aims …

Technology Agency On Usage: Grounded Theory And Measurement Of Technology Induced Usage Behavior, Sandip Kumar Sarkar

Graduate Theses and Dissertations

Most of today’s software applications involve a dyadic interplay between human and technology agency. The use of algorithms driven by user can alter users' interaction patterns by affording them novel and relevant technology action possibilities. I argue that algorithmic activities and features embedded in apps can keep users on IT applications (apps) for longer periods of time. I refer to the behavior of interacting with the apps for longer time than planned as technology-induced excessive use. While practitioners are beginning to recognize characteristics of technology-induced excessive use, research on this topic is very limited. I used a multimethod approach to …

Through The Heart Of The City: Interstates And Black Geographies In Urban America, Airic Hughes

Graduate Theses and Dissertations

Federal urban renewal projects changed the landscape of numerous American cities throughoutthe twentieth century. Many of these projects worked cohesively in tandem with discriminatory urban planning policies such as redlining. The conclusions of this project demonstrate how U.S. Interstate 630 (I-630) intentionally re-segregated Arkansas' capital city, following the U.S. Supreme Court’s 1954 national desegregation order and the infamous desegregation of Little Rock Central High School in 1957. I further contend that I-630 was constructed using the racialized language and tactics of urban renewal and was fundamental to improving Little Rock’s national reputation by purging the city's social memory and legacy …

Is Artificial Intelligence A Double-Edged Sword? Insights From Three Essays On Its Impacts, Ankur Arora

Graduate Theses and Dissertations

"If we do it right, we might be able to evolve a form of work that taps into our uniquely human capabilities and restores our humanity. The ultimate paradox is that this technology may become a powerful catalyst that we need to reclaim our humanity." - John Hagel

Artificial intelligence (AI) is viewed as a disruptive technology that some executives believe will take over a lot of jobs. However, others believe that AI will bolster growth, improve business processes, and create new business opportunities. This dissertation focuses on the tension arising from such contrasting expected impacts of AI. Extant research …

An Innocent Bystander Walks Into A Bar: The Influence Of Temporal Proximity And Familiarity On Unconscious Transference, Nia Gipson

Graduate Theses and Dissertations

According to The Innocence Project, 69% of DNA exonerations in the United States involved mistaken eyewitness identification as a contributing factor to these errant convictions. Psychologists have contributed towards minimizing mistaken identifications by proposing best practices that law enforcement still follow today. One understudied cause of mistaken eyewitness identification is unconscious transference (UT). UT is a memory error in which a person encountered in an innocent context becomes confused with a person seen in a guilty context (Loftus, 1976). Past research has established some boundary conditions for when UT can occur; however, the limited methodology has resulted in narrow conclusions …

The Effects Of Consumer Loan Application Formats And Advertised Terms On Consumer Borrowing Decisions, Alicia M. Johnson

Graduate Theses and Dissertations

Consumers continue to demonstrate a willingness to accrue more debt. They are also more accepting of increased repayment risk via the acceptance of longer loan terms. Extant research on consumer borrowing consists primarily of experiments designed to assess consumer choices and understand how consumers evaluate loan attributes in relation to one another within consumer borrowing contexts (Kamleitner, Hoelzl, and Kirchler 2012; Ranyard et al., 2006). Thus, prior research examines consumer responses to loan information rather than the generation of loan parameters at the time of financing. With important implications for consumers, marketers of financial products, academic researchers, and federal regulators, …

Collaborating With Big Brothers Big Sisters And Parents To Develop Caregiver-Initiated Mentoring, Meredith J. Scafe

Graduate Theses and Dissertations

Research shows that youth enrolled in formal mentoring programs often wait months before being matched with a mentor. This paper describes the development and pilot test of Caregiver-Initiated Mentoring (CG-IM), a program originally designed to equip caregivers to assist Big Brothers Big Sisters (BBBS) mentoring program staff in identifying and recruiting mentors from their social network. Using a mixed-methods design, the initial efficacy of the CG-IM program was evaluated via a small pilot test. I broadly explored caregivers’ experiences participating in the CG-IM program and a BBBS staff member’s experience implementing it. Caregivers completed a post-survey that included quantitative measures …

Mentors In Violence Prevention: Differential Impacts On Adolescent Bystander Intentions About Bullying, Dating Violence, And Sexual Harassment, Ayla Mapes

Graduate Theses and Dissertations

Bystander approaches are promising interventions that can engage bystanders as prosocial allies to intervene in interpersonal violence situations among youth within school settings. The Mentors in Violence Prevention (MVP) bystander intervention program targets interpersonal violence using a peer-to-peer mentoring model to engage students in a discussion about violence prevention. Research on the MVP program is promising but limited. The current study examined the specificity of MVP intervention effects in two high school samples. The first was a pre/post-test design that included a smaller sample of high school students who participated in the MVP program in the 2013-2014 academic year. The …

The Social Ontology Of Psychiatry: Psychiatric Diagnosis As An Ontogenetic, Interpellative Speech Act, Ashton Sorrels

Graduate Theses and Dissertations

Psychiatry is the study, evaluation, and treatment of mental disorders – disorders that affect the behavior and cognition of individuals and which are associated with underlying dysfunctions in the brain and nervous system. Though psychiatry is a medical and scientific discipline, it also takes place within a social context that modifies its effects, particularly in its application of diagnostic categories to individuals. In this thesis, I argue that, because of this context, psychiatric diagnosis can be modeled as an ontogenetic, interpellative speech act. A speech act is an utterance or sign that constitutes an action through its performance, called an …

Hiding In Plain Sight: Accounting For Rate Heterogeneity In Trait Evolution Models, James Boyko

Graduate Theses and Dissertations

Within the last four decades, phylogenetic comparative methods have become the defacto method of analysis for comparative biologists. The availability of high-quality comparative datasets has been matched by an explosion of possible phylogenetic models. In large part, the efforts to increase the realism of phylogenetic comparative methods has been successful as evidenced by their widespread use. To this extensive literature, my contributions are modest. I have focused my dissertation work on two main themes. First, most phenotypic evolution is not independent of other phenotypes. Changes in a particular character may influence changes in another and modeling these characters in isolation …

Examining The Intersection Of Cultural Competence And Classroom Management Self-Efficacy In Northwest Arkansas K-6 Teachers, Bonnie Culp King

Graduate Theses and Dissertations

This study aims to examine the relationship between Northwest Arkansas K-6 teachers’ cultural competence and classroom management self-efficacy. Multiple linear regression will be the quantitative approach used for analyzing K-6 teachers’ self-reported data. Valid and reliable instruments will be used to measure the concepts as operationalized for this study. Cultural competence will be measured using the “Multicultural Teaching Competency Scale” and classroom management self-efficacy will be measured using the “Teachers’ Sense of Efficacy Scale.” Demographic information will be collected to control for two variables: a teacher’s years of experience in teaching and race/ethnicity. Descriptive statistics and inferential statistics will be …

Church, Country, Culture: How Three Aspects Of Authoritarianism Predict Support For Donald Trump, Trenton Leslie

Graduate Theses and Dissertations

In the American bipartisan system, ideologies and beliefs create political views that sort voters between two groups. Political sorting increases polarization based on cultural preferences for an in-group that become ethnocentric views, which develop into ethnocentric cultural politics. I present an augmented concept of authoritarianism in America that encompasses sorting based on aspects of political belief, encapsulating sources of polarization and cultural attachments to political associations.

I develop the argument that authoritarianism is the result of political attachment to identities that feed off one another as individuals identify with an in-group, such as a party platform. My central theory is …

A Script And Acting Analysis Of David Mamet’S Glengarry Glen Ross, Abdelrahman Metwally

Graduate Theses and Dissertations

Glengarry Glen Ross is a Pulitzer Prize-winning play by David Mamet. This paper is a practical guide for the actor to understanding the events of the play and, specifically, to approaching the role of Richard Roma, with a particular emphasis on Michael Chekhov’s psycho-physical work. First, I will discuss the circumstances, values and themes of the world of the play in relation to the character Shelley Levene as the main agent of the events. Then my focus in character analysis will shift to Richard Roma as the lead character of the ensemble. Together, the two characters create a contrasting duo …

Discrete Choice Experiments In Agricultural And Food Economics: Two Essays On Information Provision Modalities, Uncertainty Adjustment, And Hypothetical Bias, Monsoïa Arsène Juste Agossadou

Graduate Theses and Dissertations

Stated discrete choice experiments are extensively used in applied economics to study preferences and valuation for new products, as well as costs and benefits of new policies and programs. Moreover, information provision experiments widely use the method to examine information effects on different outcomes. This thesis explores two methodological issues in discrete choice experiments: (i) information provision modalities and (ii) hypothetical bias. The first study examines the effect of information modality by testing the effect of using combined text script and audio clip (treatment) versus only text script (control) to convey information in discrete choice experiments. Specifically, the study elicits …

Characteristics Of Collegiate Ranch/Stock Horse Teams And Team Member Perceptions Of Benefits Of Participation, Ashton Rein Williams

Graduate Theses and Dissertations

The purpose of this study was to describe characteristics of collegiate ranch horse teams and team member’s perceived benefits from participation. A lack of research and literature on this category of competition, that is rapidly growing in popularity, is the problem that this study was designed to solve. In recent years, students have begun choosing where to further their education based upon their participation on a ranch horse team. With collegiate ranch horse teams being prevalent, there is a need for a simplified presentation of facts about the teams that can be referenced. This study will be used to guide …

Characterization Of Genetic Pathways Involved In Resistance To A Novel Antifungal Peptide, Kayla L. Haberman

Graduate Theses and Dissertations

Antibiotic resistance is increasing prevalence, particularly in Candida glabrata. This opportunistic pathogen is closely phylogenetically related to Saccharomyces cerevisiae; however, its characterization is limited. C. glabrata is only second to Candida albicans as a fungal pathogen in immunocompromised patients. Commonly resistant to azoles, the most common fungal therapy, it has become costly and challenging to treat. A histatin 5 derived antifungal peptide, KM29, has a high degree of efficacy in Candida species and S. cerevisiae. The objective of this work is to advance our understanding of the mechanism of action of KM29 against C. glabrata. Previous work in the lab …

Exploring The Divergent Social Dimensions Of Ceo Narcissism On Internal Firm Outcomes, Andrew Brandon Blake

Graduate Theses and Dissertations

In this study, I move away from the common clinical conception of narcissism in management to a novel two-dimensional concept and measurement of narcissism. Because these dimensions are shown to have divergent motives, goals, social strategies, and behaviors, I theorize that these differences in narcissism will have diverging effects on the firm. Then, I shift the conceptual focus of CEO narcissism research from the CEO as an agentic decision-maker seeking external praise for firm consequences to an implicit social strategist who prioritizes short-term interpersonal interactions in service of narcissistic supply. I examine four internal outcomes likely to be influenced by …

Gender Neutral Parenting: Raising A Generation Outside The Gender Binary, Toni Noelle Martinez

Graduate Theses and Dissertations

In the United States, the social and cultural reality remains organized around the gender binary. The binary legitimizes itself on the widely held belief that gender is determined by biology and, therefore, is “natural.” By exploring and firmly placing gender as a cultural construct, this thesis looks at the possibilities of fracturing the binary. Borrowing from Stephan Hirschauer (1994) and Judith Butler’s (2004), this thesis theorizes what a gender neutral world could look like and examines how Gender Neutral Parents contribute toward a gender revolution. Gender Neutral Parents, a community that is mostly found online, represent a small group that …

Court Actor Decision-Making: The Influence Of Victim Characteristics On Legal Outcomes In Cases Of Bias Homicide, Taylor June

Graduate Theses and Dissertations

While most states in America have passed laws permitting harsher punishments for those convicted of hate (or bias) crimes, there has been no research to date on the adjudication of these defendants, including how legal and extralegal attributes of bias crime shape prosecutorial and judicial decision-making. This gap in research is likely due in part to the limitations of official data on bias crimes. Fortunately, new data on legal outcomes for bias homicide offenders who target victims because of their race, ethnicity, nationality, religion, sexual orientation, gender identity or homed status have become available from the open-source database known as …

Three Essays On The Effect Of Scarcity On Consumer Behavior And Firm Performance, Pritosh Kumar

Graduate Theses and Dissertations

Studies have consistently shown that scarcity plays a significant role in shaping decision making. Under conditions of scarcity, individuals tend to behave impulsively, and firms are inclined to redefine their set of priorities and strategies, ultimately impacting their performance. Considering the scant investigation of the mechanisms and effects of scarcity in the supply chain management literature, this dissertation aimed to investigate the roles of scarcity in shaping consumer behavior and firm strategy in three essays.

The first essay investigated the effect of post-stockout scarcity disclosures on consumer responses to stockouts through the lens of product scarcity and signaling theory. The …

Can I Choose My Offer: How Choice On Sales Offer Impacts Consumer Purchase Decision?, Atmadeep Mukherjee

Graduate Theses and Dissertations

While making a purchase decision consumers tend to evaluate various assortments. Most of the research in choice literature has focused on the impact of focal product assortment size and consumer preferences. With the advent of a novel sales promotion strategy, where consumers are provided with a choice to select an offer, this dissertation investigates the effect of choice on sales offer, specifically free offers on purchase evaluations. Building on choice literature and sales promotion this dissertation argues that choice on sales offers, particularly free offers, will have a positive effect on purchase evaluations and the effect gets accentuated under certain …

Hurting To Helping: Regret As A Potential Motivator Of Helping Behavior, Chandler Ann Findley

Graduate Theses and Dissertations

Previous research has suggested that emotions can influence people’s motivation to engage in prosocial behaviors. Even negatively-valenced emotions, like sadness, guilt, and shame, have been shown to motivate prosocial behaviors. Exploratory analyses of a previous study indicated that regret may also motivate increased prosocial intentions, but no research has been published to experimentally test whether feelings of regret may motivate prosocial behaviors. Therefore, the present research seeks to experimentally manipulate participants’ current emotional state to empirically examine whether regret motivates greater helping behavior than other, similar negative emotions that have already been demonstrated to motivate prosocial behaviors in humans. These …

Examining First-Year, First-Generation College Students' Perceptions Of Parental Involvement, Quincy D. Spencer

Graduate Theses and Dissertations

Parental engagement and support have been shown to have a positive impact on the academic performance, mental health, and overall well-being of undergraduate students (Harper et al., 2012). While continuing-generation college students utilize knowledge and insight from their parents to navigate the collegiate experience, first-generation undergraduate students face hurdles that can impact their experience due to the unfamiliarity associated with being the first in their family to pursue higher education. The purpose of this qualitative study was to examine underrepresented first-year, first-generation undergraduate students’ perceptions of their parent(s) involvement when deciding to attend college, high school to college transition, and …

An Evaluation Of The Convergent Construct Validity Of The Boldness Inventory Of Psychopathy Using A Five-Minute, 10% Carbon-Dioxide-Enriched Air Challenge, Morgan Alexandra Hill

Graduate Theses and Dissertations

Psychopathy is a constellation of maladaptive interpersonal, affective, and behavioral features, including grandiosity, manipulativeness, emotional detachment, and impulsivity (Hare, 2003). Fearlessness, immunity to stress, self-assurance, and social dominance are considered to be adaptive features of psychopathy. Patrick and colleagues (2009) sought to reconcile differences between opposing conceptualizations of psychopathy by formulating a triarchic model of the condition. One core construct in this model, boldness, captures an ability to remain calm in the face of threat, an appetite for dangerous or risky activities, and an increased tolerance for uncertainty and danger. Boldness is believed to originate from differences in the brain’s …

The Relationship Between Psychosocial Factors And Food Waste-Related Behaviors Among College Students, Kacy Raquel Wright

Graduate Theses and Dissertations

Food waste is a significant environmental, economic, and social issue, with younger consumers as the most significant contributors. Specific behaviors, like over-purchasing food and misusing date labels, result from a complex interaction between social and psychological factors, which influence food waste among this demographic. The purpose of this study was to identify the psychosocial factors influencing food waste behaviors among college students at the University of Arkansas. Guided by the Theory of Planned Behavior, this study utilized online and face-to-face quantitative surveys, distributed to students enrolled at the University of Arkansas in the spring of 2022. Demographics, attitudes, subjective norms, …

The Effects Of Immersive Virtual Environments On Motivation, Oral Communication, And Instructional Strategy In Efl Classrooms, John Martin Shipko

Graduate Theses and Dissertations

The creation of web-based real-time computer simulations has given language educators incredible new opportunities to create immersive experiences for English as a Foreign Language (EFL) learners. This thesis reviewed 12 empirical studies, 3 previous literature reviews, 3 non-empirical journal articles, and 23 additional background sources investigating the impact of Immersive Virtual Environments (IVE) on EFL learners’ motivation and oral communication in EFL learning. 12 empirical studies were analyzed closely while other sources were used to provide additional information and theoretical insights. The findings indicate that IVEs offer novel ways to connect EFL learners to native-speaking communities where they can acquire …

Diversity, Equity, And Inclusion: Three Essays In The Educational Context, James D. Paul

Graduate Theses and Dissertations

Many universities and K-12 public school systems express a significant, formal commitment to the ideals of diversity, equity, and inclusion (DEI). Relative to the emphasis on DEI in America’s educational institutions, however, there has been little research describing DEI trends and evaluating the efficacy of DEI bureaucracies. This three-chapter dissertation examines DEI trends that have been the subject of much discussion—but rarely studied empirically.

For example, chapter one analyzes how universities promote DEI when hiring new faculty. I audit a subset of academic job postings and present the first evidence on how many require DEI statements, as well as the …

Children’S Positive Peer Relationships And Their Bullying Behaviors: A Latent Profile Analysis, Lauren Mutignani

Graduate Theses and Dissertations

In the current study, I aim to expand upon traditional methods for classifying children based on positive peer nominations and contribute to the field’s understanding of high-status bullies who maintain social resources despite bulling behaviors (e.g., van der Ploeg et al., 2020). Both reciprocated and one-sided (i.e., received and sent) positive peer nominations were used to distinguish socially meaningful subgroups. Participants included 659 children from 34 classrooms (M Age = 9.31 years, SD = .49 years; girls = 50.6%; Hispanic/Latino/a/x = 42.5%, White/European American = 29.9%, Black/African American = 2.3%, Asian/Asian American/Pacific Islander = 11.7%, Native American = 2.3%, Bi/Multiracial …

Mental Health Stigma And Psychological Help-Seeking In Adolescence, Laura Austin

Graduate Theses and Dissertations

Although an overwhelming number of adolescents in the U.S. experience significant psychological distress, the majority of these youth do not receive formal mental health services. Mental health stigma has been identified as a significant barrier to psychological help-seeking during adolescence, with treatment stigma (or the stigma associated with seeking formal psychological services) as the strongest predictor of help-seeking when compared to other types of mental health stigma. Given the long-term impacts of untreated psychological distress in adolescence, more research is needed to understand the influence of mental health stigma on help-seeking during this developmental stage. Furthermore, more research is needed …
