The Reinforcement Enhancing Effects Of Delta-9-Tetrahyrdrocannabinol (Thc) In Male And Female Rats, Kynah Walston

Electronic Theses and Dissertations

Cannabis is widely consumed by humans for pharmacological effects that are mediated by THC, though there is little evidence that THC is a primary reinforcer in non-human animal models. We hypothesized that THC may have potent reinforcement enhancing effects, comparable to other drugs (e.g., nicotine and caffeine) which are also widely consumed by humans, but difficult to establish as primary reinforcers in non-humans. In three experiments with male and female rats saccharin (SACC) or a visual stimulus (VS) served as reinforcers for operant behavior. We explored several pharmacological parameters of THC on responding for SACC or VS, including THC dose, …

Dyadic And Ecological Associations With Intimate Partner Violence (Ipv): Using Hierarchical Linear Modeling To Differentiate Ipv From Community Crime, Rachel Carpenter

Electronic Theses and Dissertations

Research on intimate partner violence (IPV) and intimate partner sexual violence (IPSV) has largely focused on individual and dyadic-level risk factors, but recently studies have explored how the surrounding environment is associated with IPV/IPSV. Studies that have explored community-level variables typically only use IPV/IPSV samples and do not first compare indicators of IPV/IPSV to those of general crime in those same communities. To address these gaps, this study was conducted in two parts. Data were retrieved from the Tennessee Bureau of Investigation Reporting System, County Health Rankings and Roadmaps System, the US Census Bureau, and other sources. Study 1 first …

Trust Is Not Enough: Examining The Role Of Distrust In Human-Autonomy Teams, Sydney Begerowski

All Theses

As automation solutions in manufacturing grow more accessible, there are consistent calls to augment capabilities of humans through the use of autonomous agents, leading to human-autonomy teams (HATs). Many constructs from the human-human teaming literatures are being studied in the context of HATs, such as affective emergent states. Among these, trust has been demonstrated to play a critical role in both human teams and HATs, particularly when considering the reliability of the agent performance. However, the HAT literature fails to account for the distinction between trust and distrust. Consequently, this study investigates the effects of both trust and distrust in …

Awe And Relationship Quality, Gloria Junyan Lai

Dissertations and Theses Collection (Open Access)

The experience of awe has been studied as having self-transcending outcomes that produce a decrease in importance of the individual’s interests and an increase in the interests of others. This shift in self-concept is said to be a sense of self-diminishment vis-à-vis perceived vast stimuli. When applied to a romantic relationship context, it is possible that a shift of attention away from self-serving motives, towards relationship-enhancing motives, may promote positive relationship outcomes. As such, the current study examined how experimentally induced awe may influence relationship commitment and forgiveness via an expected increase in self-diminishment. 607 participants were randomly assigned to …

Employee Perceptions Of Stressors At Work: An Attachment Perspective, Emma Josephine Naudet

Electronic Theses, Projects, and Dissertations

The current study applied an attachment perspective to elucidate how individuals appraise stressors at work. Attachment theory proposes that individuals’ interactions with a caregiver shape their expectations and beliefs about the world, themselves, and others and predict how individuals behave. Attachment at work is a budding research topic because it informs the social aspect of work relationships, such as the leader-subordinate dyad. However, few studies have explored the potential of attachment security as a job resource. Our findings demonstrated strong support for our predictions about the relationship between transformational leadership, employee perceptions of demands and resources, and the potential explanatory …

Developmental Differences In School Climate Predictors Of Chronic School Absenteeism, Michael Fensken

UNLV Theses, Dissertations, Professional Papers, and Capstones

School attendance problems (SAPs) represent a critical developmental challenge for youth. SAPs represent a spectrum from difficulties attending school despite complete school attendance to complete absence. Ongoing SAPs can lead to chronic absenteeism, which may be defined as missing 8.3–10.0% (15–18 days) of school in an academic year. However, debate exists over the utility of a demarcation for chronic absenteeism. A shortcoming of cutoffs to defining problematic chronic absenteeism is that demographic, academic, symptom, and family variables are not delineated clearly. Yet, the present intervention frameworks (e.g., multi-tiered systems of supports models; MTSS) rely on clear delineations of such variables …

Self-Perceived Stigma Of Caregivers With Children On The Autism Spectrum In Latin America, Leah Michelle Jara

Theses and Dissertations

With the prevalence of Autism Spectrum Disorder (ASD) continuing to spread along with limited knowledge on the disorder’s service accessibility, many caregivers are required to care for lifelong obligations, often at the sake of their own mental, physiological, and emotional health. This study aimed to explore self-perceived stigmas of caregivers in Latin America based on predictors including demographics, severity, and type of healthcare coverage. Participants included 2483 caregivers in Latin America who completed a survey targeting the challenges, priorities, barriers to care, and stigma they face caring for an individual with autism. Findings showed that age had a weak inverse …

Empirical Evaluation Of A Novel Spatial Disorientation Induction Strategy, Michaela Cathlin Satter

Theses and Dissertations

It is estimated that spatial disorientation-related accidents account for roughly 33% of all aviation mishaps with a 90% fatality rate (Gibb et al., 2011). Research meant to establish common practices and standardization of spatial disorientation (SD) training is needed to work toward decreasing this staggering statistic. The current study investigated the viability of a novel SD Induction Strategy that combined rotation about the vertical axis, visual cue input from a wireless virtual reality (VR) head mounted display (HMD) flight environment, and tactile input from a wireless joystick controller. To assess this combination’s effectiveness, Bank situation awareness (SA) and Pitch SA, …

Exploring Factors That Influence Disagreements In Self-Other Ratings In 360-Degree Feedback Systems, Robert Allen Miller

Theses and Dissertations

360-degree feedback systems are some of the most widely used ratings systems in organizations today. The current study examined the use of 360-degree feedback systems as a method for capturing job performance in organizations and the challenges associated with accuracy in ratings due to individual differences in perception. The study investigated the links between self-other rating tendencies and narrow facets of personality and examined how an individual’s personality affects self- and other-ratings of their performance behaviors. The findings suggest that various aspects of personality differentially affect both self- and other-ratings of performance, providing a deeper understanding of how individual differences …

A Multi-Level Comparison Of Increasing Training Modalities To Train Behavior Analysts To Conduct An Intensive Pediatric Feeding Intervention, Ronald Joseph Clark

Theses and Dissertations

A common focus within behavior analytic clinical practice is to incorporate training with caregivers to promote successful transition of clinical services. In the pediatric feeding literature, for example, training caregivers to ensure maintenance and generalization of the intervention is expected. However, training staff members to provide specific behavioral interventions has received less attention. The current study systematically implemented three levels of training to evaluate the level of intensity required to train behavior analytic staff (i.e., behavior technicians, Registered Behavior Technicians®, and Board-Certified Behavior Analysts®) to implement a feeding protocol with a role play partner. Only one participant met the mastery …

Effect Of Brain Injury On Demand Of Alcohol, Whitney Michele Chaney

Theses and Dissertations

Brain injury, or damage to the brain and/or surrounding structures, is listed by the CDC as the leading cause of disability and death in the United States. This kind of injury can result in symptoms that physical, cognitive, and behavioral functioning in those affected. Despite this, current literature reflects a significant deficiency in the understanding and management of behavioral symptoms, that present after the injury, in most neurorehabilitative treatments. This study aimed to investigate whether sustaining a brain injury can effect an individual’s demand intensity for alcohol, if their demand was inelastic, and their probability for misuse of alcohol. To …

Monoracials’ Perceptions Of Biracials In Singapore, Sheila Xi Rui Wee, Chi-Ying Cheng

Research Collection School of Social Sciences

Objectives: Drawing on social identity theory, present research examined the effects of overlapping racial membership on monoracials’ categorization of biracials as in-/out-group members, as well as its impact on monoracials’ social perceptions of biracials in Singapore. Within Singapore, it is hypothesized that biracials who share racial membership with monoracials would be rated more as monoracials’ racial in-group and be evaluated more positively. Furthermore, monoracials’ positive perceptions of biracials with (vs. without) shared racial membership would be less influenced by biracials’ confrontation of racial prejudice. Method: Studies 1 (N = 242) and 2 (N = 153) sampled Chinese Singaporeans to assess …

The Future Of Socialization: Linking Socialization To Employee Engagement, Alexander Michael Dechurch

Theses and Dissertations

This study examines the relationship between socialization and engagement. In doing so this study investigates and measures the impact that social integration, task mastery, autonomy, role clarity, satisfaction with socialization, job embeddedness, network characteristics, network capital, and online socialization have in linking socialization to engagement. The sample for this study utilized data from Amazon Mechanical Turk. The results suggest that institutionalized socialization tactics relate to higher reported engagement. In addition, social integration, autonomy, job embeddedness, network strength, and network capital each play a significant role in the observed relationship

Bilingual Profiles Differentially Predict Executive Functions During Early Childhood: A Latent Profile Analysis, Hwajin Yang, Germaine Y. Q. Tng, Wee Qin Ng, Sujin Yang

Research Collection School of Social Sciences

Recent studies suggest that heterogeneous bilingual experiences implicate different executive functions (EF) in children. Using a latent profile analysis, we conducted a more nuanced investigation of multifaceted bilingual experiences. By concurrently considering numerous bilingual indicators – age of L1 and L2 acquisition, interactional contexts of verbal exchanges, L1 and L2 proficiency, balance of language use at home and school, and receptive vocabulary – we identified three latent profiles (subgroups): balanced dual-language, dominant single-language, and mixed-interaction. We found that the balanced dual-language and dominant single-language profiles predicted significantly better switching than the mixed-interaction profile. However, no profile differences were found in …

The Impact Of Music Therapy On Language Acquisition In Children With Nonverbal Autism, Alecia Bernau

Senior Honors Theses

Through an experimental method, the researcher investigated whether children with autism spectrum disorder (ASD) are more likely to develop verbal communication skills after consistent exposure to songs with lyrics. Six children with nonverbal ASD were exposed to the same song with lyrics, with the goal of increased vocalization and language acquisition. Over nine sessions, subjects were pulled to participate in the experiment. The researcher played the song for the participants, recording the responses from each trial and categorizing them as either full words, verbal approximations, or miscellaneous verbalizations. The findings of the study suggest that there is a relationship between …

Rattus Norvegicus As A Biological Detector Of Clandestine Remains And The Use Of Ultrasonic Vocalizations As A Locating Mechanism, Gabrielle M. Johnston

Master's Theses

In investigations, locating missing persons and clandestine remains are imperative. One way that first responder and police agencies can search for the remains is by using cadaver dogs as biological detectors. Cadaver dogs are typically used due to their olfactory sensitivity and ability to detect low concentrations of volatile organic compounds produced by biological remains. Cadaver dogs are typically chosen for their stamina, agility, and olfactory sensitivity. However, what is not taken into account often is the size of the animal and the expense of maintaining and training the animal. Cadaver dogs are typically large breeds that cannot fit in …

The Diagnostic Odyssey Of Hypermobile Eds Patients: Diagnosis, Clinical Expectations, And Psychosocial Concerns, Madeline Alpar

Dissertations and Theses (Open Access)

Background: Ehlers-Danlos syndrome (EDS) is a highly variable, heritable connective tissue disorder. Hypermobile EDS (hEDS) is the most common subtype of EDS and has no identifiable underlying genetic etiology. Patients with clinical features of hEDS face a long diagnostic odyssey due to lack of genetic testing and wide clinical heterogeneity. Additionally, recent research has shown that genetic institutions limit evaluations for suspected hEDS, adding another barrier to care.

Methods: We developed an online patient survey to explore the diagnostic odyssey of hEDS for those who were diagnosed with or suspicious for hEDS. This survey included sections on demographics, diagnostic information …

Resilience To Stress Across The Lifespan: Childhood Maltreatment, Heart Rate Variability, And Bereavement, Michelle A Chen, Robert Suchting, Julian F Thayer, Christopher P Fagundes

Faculty, Staff and Student Publications

Following a stressful life event, there is considerable variation in how individuals respond and adapt. Multiple models of risk and resilience show that adverse childhood experiences may be associated with an individual's response to stress later in life. While there is considerable support that early adversity can sensitize the stress response system and lead to adverse outcomes later in life, there is mounting evidence that in adolescence and young adulthood, certain biological predispositions to stress may be associated with resilience in the context of subsequent stressors. In this study, we evaluated how individual differences in vagally mediated heart rate variability …

Making The Subconscious Conscious - Showcasing Unresolved Childhood Trauma Through Animation, Alexis Hunter

All Theses

The focus of this work is to shed light on unresolved childhood trauma that can contribute to mental hardships - whether people are aware of its presence in their lives or not. In this paper, I will discuss childhood trauma, its impact on adult life when left unresolved, self-parenting as a method to manage it, and how it is portrayed in various media. Drawing inspiration from my research on trauma and visual storytelling, I will present a proof-of-concept for a 2D animated short film, Strongholds, which visualizes the internal mental struggles through the character dynamics of the personifications of the …

Individual Differences In Vulnerability To Phishing, Fake News, And Vishing, Jeff Black

All Theses

Digital deception, such as phishing emails, scam phone calls, and fake news, poses a threat to anyone using digital devices. Research on digital deception often points to individual differences like age, cognitive impulsivity, and digital literacy, but has only investigated different types of digital deception independent of each other. Therefore, it is unclear whether users vulnerable to one type of deception are also vulnerable to others, and why. The present research examined relationships between vulnerability to different types of deception, and how this vulnerability is associated with common individual differences like age, cognitive impulsivity, digital literacy, and gullibility, and exploratory …

Steps Toward Healing From The Possessive Other: The Vital Role Of Fantastical Literature In Trauma Theory, Rebekah Izard

English (MA) Theses

Fantastical narratives such as fairy tales and magical realist literature utilizes fantastic and intangible spaces to unpack that which is often beyond the limitations imposed on our understanding by reality: the stunting experience of individual and generational traumas. This study aims to contribute to the current literary discourse’s understandings of fantastic literature and its subgenres as a tool for healing from trauma through the application of ontological notions of Selfhood and Otherness supplied by 20th century philosopher, Paul Ricoeur, and the notion of Orientalism by postcolonial scholar, Edward Said. The dialogue generated by these schools of thought provide a space …

Parental Well-Being And Children’S Internalizing Symptoms During The Beginning Of The Covid-19 Pandemic In The United States, Diana Duran

Theses and Dissertations

During the beginning of the COVID-19 pandemic stay-at-home orders in the U.S., many parents of school-age children faced new challenges, such increased child-care demands (Adams, 2021). Prime et al. (2020) theorized these negative pandemic impacts would decrease parents' well-being and thereby impact children's psychological adjustment. This study hypothesized that higher number of negative pandemic impacts would predict worsened stress and relationship satisfaction levels among parents, and that this would in turn predict worsened child internalizing symptoms. 595 U.S. parents of school-age children were recruited online during May 2020. Higher number of negative pandemic impacts predicted worsened parents' stress and relationship …

Approaching Trans Healthcare Competency: The Implementation Of Trans Health Education For Medical Providers In Appalachia, Rebecca Altschuler

Electronic Theses and Dissertations

Barriers to competent and safe healthcare disproportionately impact people who are marginalized because of their race, ethnicity, gender, or socioeconomic status. It is well documented that transgender patients in particular experience barriers to both accessing care and receiving high quality, non-discriminatory care (Hatzenbuehler & Pachankis, 2016; James et al., 2016; Rahman et al., 2019; Safer et al., 2016). This lack of access to culturally competent healthcare services contributes to health disparities that disproportionately impact the trans community. Literature on barriers to competent care for trans patients indicates that providers experience discomfort related to their ability to provide competent care (Safer …

Preference For Abstinence-Based Recovery And Public Stigma Toward Substance Use Disorders, Diamond Meadows

Electronic Theses and Dissertations

The present study drew from the publicly available Amerispeak survey (n = 6,515) and examined public stigma towards different substances, the relationship between preferences for abstinence-based recovery and stigma toward each substance, and whether perceived dangerousness of substances moderates the relationship between preferences for abstinence-based recovery and public stigma. The results indicate that the general public has greater stigmatizing attitudes towards methamphetamine use disorder than cocaine use disorder, opioid use disorder, and alcohol use disorder. Furthermore, a preference for abstinence-based recovery was associated with greater stigmatizing attitudes toward all SUDs. The perceived dangerousness of a substance did not moderate the …

The Relationships Between Academic Entitlement, Grit, Prospective Memory, Retrospective Memory, And Undergraduate Gpa, Kathrin Underwood

Honors Theses

The present study was conducted in order to investigate the relationships between academic entitlement, grit, prospective memory, retrospective memory, and GPA. To investigate these relationships, participants were asked to fill out multiple questionnaires including the AEQ, PRMQ, and the Grit Scale survey. GPAs for participants were taken from the Institutional Research, Effectiveness, and Planning office. The results of this study showed that students with high grit scores were more likely to have lower academic entitlement, higher GPAs, and higher prospective and retrospective memory scores. Ultimately, these results suggest that certain traits and abilities may be predictive of academic success. Looking …

College-Related Stress And Substance Use: Experiences Of Honors And Non-Honors Students, Melanie Fischer

Undergraduate Honors Theses

Although there is a wealth of research knowledge related to risk behavior engagement of the general student population, there is less specifically reported about honors students. To address this gap in research, non-honors and honors students were surveyed to determine possible differences in risk behavior engagement. Students were recruited through the East Tennessee State University psychology subject pool and via direct email messages to an honors student-specific listserv. We hypothesized that honors students would have differences in terms of GPA and number of credit hours, endorse more substance use and have more perceived stress compared to non-honors students. The survey …

Undergraduate Honors Theses

Parents’ adverse childhood experiences in relation to parent-child emotion socialization

Objective: Parents have an integral role in a child’s development of important emotional and psychosocial processes through emotion socialization. The goal of this paper is to examine the presence of adverse childhood experiences during the parents’ childhood and adolescence alongside the parents’ responses to their child’s emotional expression. The impact of adverse childhood experiences on a parent’s ability to socialize their child’s emotions is a key factor in the continued objective of cultivating positive parent-child interaction and improving adolescent mental health.

Methods: Participants were 165 adolescents and their parents. Adolescent …

Assessing The Learning Of Qualitative Research Through A Critical Reflective Essay, Elida Cena, Stephanie Burns

The Qualitative Report

Despite a longstanding commitment to the notion of reflection as an integral part of qualitative research, there are few explicit learning tools or published assignment guides to aid understanding of this important aspect of student learning. Reflection both as a researcher and within the context of an educational perspective can be challenging; however, creating reflective assignments can help students consolidate and assess the learning of qualitative research skills in practice. This article describes a critical reflective assignment highlighting the challenges, rewards, and reflections on designing and conducting an interview process as part of a qualitative research methods module with postgraduate …

The Role Of Organizational Support In The Relationship Between Safety Climate And Organizational Outcomes, Lee Chambers

Electronic Theses, Projects, and Dissertations

Organizations employing individuals in high-risk or safety-sensitive occupations (e.g., construction workers, commercial drivers, pilots, and oil rig workers) face the challenge of ensuring their employees’ safety and well-being amidst various hazards and dangerous situations. To address this, cultivating a positive safety climate has been identified as a crucial factor in reducing workplace accidents or injuries. However, despite its importance, the link between safety climate and non-safety outcomes remains underexplored in the literature. In response, this study proposed a model based on social exchange theory, which highlights the crucial role of organizational support in explaining the relationship between safety climate and …

The Impact Of Transformational Leadership And Workplace Relationships On Employee Burnout And Their Correlation To Turnover Intention And Organizational Commitment, Teni Davoudian

Electronic Theses, Projects, and Dissertations

Organizations are built through the contributions of their employees, which is why when employees leave, organizations suffer a significant loss. This can be foreseen by an employee’s level of organizational commitment and burnout which contribute to turnover intention. Measures can be taken to reduce burnout through nurturing leadership and the development of healthy workplace relationships. The purpose of this study is to examine the respective relationship between transformational leadership and workplace relationships on turnover intention and organizational commitment with interest in the mediating role of employee burnout. Leadership has a strong influence on individuals and organizations. It largely contributes to …
