Social Anxiety And Cannabis Use Context, Brooke Beckius

Dissertations and Theses

Cannabis use is highly prevalent among young adults in the United States, with many experiencing associated problems. Social anxiety has been identified as a significant risk factor for cannabis use and related consequences; however, it remains unclear whether cannabis facilitates or inhibits social engagement among socially anxious individuals. Solitary cannabis use is consistently linked to use-related problems, but the term “solitary use” may encompass distinct contexts—such as social preparatory use, use to aid sleep, or use while spending time alone. The present study aimed to examine how cannabis use influences social engagement among socially anxious individuals and test how specific …

Saving Tomorrow: The Triumphs And Tribulations Of Innovational Behavioral, Social-Emotional, Or Mental Health Support In A Rural Public School, Andrea Powell

Dissertations and Theses

Although some research has established the use of diffusion of innovation in technical fields, few studies show its utilization in public schools. This qualitative case study aimed to understand the trials and tribulations associated with implementing behavioral, social-emotional, or mental health support in a rural K–12th public school. Further, this study sought to understand how innovation diffuses throughout public school districts. Specifically, this qualitative study analyzed the perception of innovation through survey data collected from teachers and administrators in a rural K–12th grade public school district. When implementing behavioral, social-emotional, or mental health supports in a rural school, five themes …

Upward Distortion And Organizational Culture, Benjamin Gellerman

Dissertations and Theses

The “MUM effect," a social phenomenon in which people prefer to avoid sharing bad news, can cause “upward distortion,” as employees give incomplete information to their supervisors to avoid reprisal. Organizations require upward communication to transmit critical information, and disruptions to this process have implications for both workplace efficiency and job satisfaction. Strauss (2011) developed the Upward Communication Distortion Index (UCDI) to measure the propensity of individuals to distort upward organizational communication. The UCDI was compared with the subscales for LMX (leader-member exchange) and Locus of Control. This project analyzed upward distortion in American businesses, specifically how four different organizational …

The Effects Of A Game-Based Social Skills Intervention On Social Skills Acquistion For Autistic Youth In Training And Generalized Settings, Sales Libby Ann

Dissertations and Theses

Individuals with autism spectrum disorder (ASD) commonly have difficulties with social communication which is often targeted using social skills teaching (SST) (Mikami et al., 2014). These programs are effective, however, many lack evidence of social validity measures or procedures as well as generalization of the skills targeted in intervention. The current study investigated the skill acquisition of three participants through the use of social skills teaching embedded within a role-playing game. The primary dependent variable was the skill acquisition of each participant within the RPG setting. Immediate increases in level and trend were noted across participants for most skills following …

The Impact And Perceptions Of Open Educational Resources And Oer-Enabled Pedagogy On Affordability, Enrollment, And Student Success In Undergraduate Anatomy And Physiology, Justin Burr

Dissertations and Theses

Open educational resources (OER) can help improve the affordability of higher education. While the impacts of OER on student success and cost savings have been studied in some areas, the literature lacks evidence for undergraduate anatomy and physiology. Additionally, the potential impact OER has on student enrollment choices in undergraduate anatomy and physiology remains unstudied. The cost of textbooks has been a notable hurdle to higher education participation and success, particularly among minority and underserved populations. This study aimed to evaluate the impacts of OER on affordability (cost), access (enrollment), and student success. A mixed-methods approach was used to answer …

Personality Functioning And Sexual Aggression: How Criterion A Of The Alternative Model Of Personality Disorders (Ampd) Relates To Sexually Aggressive Cognitions In Men, Ryan Van Fossen

Dissertations and Theses

This study investigated how personality functioning and maladaptive traits contribute to sexually aggressive cognitions (SAC) in men, extending existing research on personality pathology. Three primary aims were examined. Aim 1 explored the relationships between SAC and the four components of personality functioning (identity, self-direction, empathy, intimacy). Aim 2 evaluated the structure of personality functioning as measured by the Levels of Personality Functioning Scale-Self Report (LPFS-SR).

Childhood Betrayal Trauma, Psychopathy, And Ptsd: The Role Of Ambiguity Tolerance, Distress Tolerance, And Impulse Control Difficulties In A College Sample., Surabhi Swaminath

Dissertations and Theses

Childhood betrayal trauma engenders negative outcomes such as post-traumatic stress disorder (PTSD) and psychopathy. Though these outcomes are viewed as functional opposites, this multi-finality suggests similar underlying mechanisms. Childhood betrayal trauma results in low tolerance for different types of distress, including emotional distress and ambiguity. Distress is known to induce impulse control difficulties, which are associated with both PTSD and psychopathy. This cross-sectional study tested hypothesized indirect associations between childhood betrayal trauma and two outcomes: PTSD symptoms and psychopathy in a sample of young adults (N¬ = 753). We hypothesized direct paths from childhood betrayal trauma to PTSD, and psychopathy. …

The Lived Experiences Of Fathers With Transgender Children Under 18 In States Banning Gender-Affirming Care, Ashley Perez

Dissertations and Theses

Parents of transgender individuals can experience numerous stressors in accessing overall care and support for their child's health and well-being. Parents can also undergo significant personal growth and change because their child is transgender. Unfortunately, the majority of the current literature focuses on mothers' experiences with transgender children. This study advances knowledge that can further support families navigating life with a transgender child, as the lived experiences of fathers are greatly lacking. Furthermore, the political and environmental scope in which the family is located can impact what families face when accessing care and support for their child and can result …

Childhood Betrayal Trauma And Suicidal Ideation: The Role Of Early Maladaptive Schemas And Interpersonal Problems, Christine Yost

Dissertations and Theses

Betrayal trauma (Freyd, 1996) is a specific form of trauma that occurs when a child is significantly harmed by someone they depend on or trust. Prior research has demonstrated that betrayal trauma is more strongly associated with adverse mental health outcomes than traumas lower in interpersonal betrayal, yet few studies have examined its relationship with suicidal ideation or identified mechanisms that explain this association. The present study tested a path model in a sample of 391 young adults aged 18-34 who endorsed suicidal ideation in the past year. The model examined whether specific early maladaptive schemas (emotional deprivation, social isolation/alienation, …

Design And Validation Of A Multiple Axis, Passive 3d-Printed Ankle-Foot Prosthetic For Functional Gait, Brogan Rene Landeen

Dissertations and Theses

By 2050, an estimated 3.6 million individuals will be living with lower limb loss, with transtibial (below the knee) amputations being the most common type of lower limb surgery. Prosthetic devices are the standard of care for rehabilitating these amputees; each device is explicitly designed to enhance stability, energy storage and release, flexibility, and active propulsion. Prosthetic selection is based on user specifications, including activity level, comfort, and anthropometry. Despite the consensus that prosthetics help to restore impaired gait, traditional, commercial prosthetics fabricated with carbon fiber via injection molding are expensive and often require multiple modifications by a prosthetist before …

Perceptions Of Plant-Based Meat And Cultured Meat Within The Northern Great Plains Region, Donald Chase Stehly

Dissertations and Theses

Conventional meat consumption derived from livestock farming is one of the leading causes of greenhouse gas emissions and environmental degradation on our planet. Substituting conventional meat products with “meat alternatives” such as plant-based meat or cultured meat would drastically decrease greenhouse gas emissions, reduce land and water pollution, and decrease land and water usage. However, it is necessary to first gauge how people feel about eating plant-based meat and cultured meat before it is possible to discern the magnitude of environmental benefits that occur with a significant dietary change such as this. By administering a questionnaire to over 400 participants …

Automated Thermo-Mechanical Therapy For Immediate Relief In Chronic Non-Specific Lower Back Pain (Cnslbp): A Randomized Controlled Trial, Kyle V. Donnery

Dissertations and Theses

Objective: Chronic non-specific lower back pain (cNSLBP) is a prevalent and disabling condition, imposing a substantial socioeconomic burden due to high healthcare costs and productivity losses, with limited accessible and effective long-term treatment options. Automated Thermo-mechanical Therapy (ATT) is a promising, non-drug intervention that leverages innovative technical advances to provide multimodal pain relief, offering accessibility and low-cost delivery. This study tested ATT for immediate pain relief in individuals with cNSLBP in a single-session, double-blind, randomized controlled trial.

Methods: Forty participants with cNSLBP were randomly assigned to receive either active ATT (n=20) or control ATT (n=20) in a 40-minute session. The …

Effects Of Mental Fatigue On Gait Performance And Variability, Ali Zardosht

Dissertations and Theses

Mental fatigue has been shown to negatively impact physical performance, including motor skills and neuromuscular function. This study aimed to investigate the effects of mental fatigue on gait performance and variability in healthy young male adults. Eighteen participants walked over-ground at their preferred speed before and after completing a mentally fatiguing Stroop task. Kinematic data were recorded to assess gait variables such as speed, step length, step time, and step width, along with their coefficients of variation (CV). While subjective ratings of mental fatigue significantly increased following the Stroop task, no significant changes were observed in gait performance or CV …

Alexander And The Influence Of Aretē, Alex Toupal

Dissertations and Theses

This thesis examines Alexander III of Macedon through the lens of aretē, the Greek ideal of excellence. Rather than viewing his ambition only as a longing (pothos) for exploration, it argues that Alexander’s drive is best understood as a competitive pursuit to embody and surpass the highest standards of his age. The study traces the development of aretē from its Homeric roots to Aristotle’s philosophical refinement, then situates Alexander’s actions within the cultural ideals of the Macedonian court and the wider Hellenic world. Using primary accounts and modern scholarship, it explores how Alexander measured himself against legendary and historical figures …

The Impact And Influence Of Sexual Interpersonal Violence And Beliefs On Barriers In Help-Seeking For College Students, Caitlin N. Bedard

Dissertations and Theses

Sexual interpersonal violence (SIPV) has significant negative impacts on college students yet there is frequent underuse of formal support resources. Consequently, understanding help-seeking for this population is vital. Current research has examined SIPV experiences, rape myth beliefs, and help-seeking barriers in isolation. However, understanding how these factors interact is crucial to understanding how to improve resources for survivors. The present study investigated the relationship among these three constructs in 89 college students who experienced unwanted sexual events after age 18. SIPV experiences, rape myth endorsement, and help-seeking barriers were all positively associated. Regression analysis revealed that four types of SIPV …

Cognitive Map Generation For Vision And Language Navigation, Alexander Sandoval Mesa

Dissertations and Theses

Visual-Language Navigation (VLN) presents significant challenges for autonomous agents, such as robots and virtual assistants, particularly in complex, dynamic environments where the seamless integration of visual perception and natural language understanding is critical. Traditional VLN systems often struggle with effectively aligning language instructions and visual scene understanding, limiting their adaptability and navigation efficiency.

This thesis proposes a novel Cognitive Map-based framework that addresses these challenges by transforming natural language navigation instructions into structured graph representations. The Cognitive Map consists of nodes representing waypoints, landmarks, decision points, and edges encoding spatial relationships and navigational actions. These maps are generated using Large …

An Exploration Of Object Representations And Defense Mechanisms In Caregiver-Child Dyads On The Thematic Apperception Test, Hannah L. Bloom

Dissertations and Theses

Caregiver-child interactions, beginning in infancy, are essential for socio-emotional development. Through these exchanges, caregivers impart fantasies, fears, and beliefs—both consciously and unconsciously—that shape the child’s internal models of self and others (object representations) and strategies for managing intense emotions (defense mechanisms). Historically, projective tests, such as the Thematic Apperception Test (TAT), have been used to explore these constructs. In the TAT, participants craft narratives based on images that portray characters in different emotional states and interpersonal situations. Through their responses, participants project elements of their own internal world into the stories they create. Despite the TAT’s success in differentiating diagnostic …

The Role Of Social Inequality In The “Feminization” Of Borderline Personality Disorder, Jane Goldie Ekhtman

Dissertations and Theses

Borderline personality disorder (BPD) is a severe and prevalent mental illness that is three times more likely to be diagnosed in women than men. BPD research has attempted to explain this gender disparity, with clinician gender bias emerging as a possible factor. Yet, no research to date has examined the role of social status in the overdiagnosis of women with BPD. There is merit in examining BPD through a class lens as low SES is a risk factor for BPD, poverty and income inequality disproportionately affect women, and low status is associated with stereotypical traits of femininity. Additionally, mental health …

Examining The Complex Interplay Of Stress, Social Support, And Drinking Motives On Alcohol Use Behaviors: A Moderated Mediation Model Among College Students, Sabrina Perrin

Dissertations and Theses

College student alcohol use remains a public health concern, yet the psychological and social mechanisms that contribute to high-risk drinking patterns are not fully understood. Guided by the motivational model of alcohol use and stress-buffering theory, this study tested a moderated mediation model to examine how perceived stress, coping motives for drinking, and perceived social support interact to influence alcohol use behaviors. A sample of over 1,100 diverse urban college students completed measures of stress, social support, drinking motives, and four alcohol-related outcomes: binge drinking, frequency of alcoholic drinks consumed, negative drinking consequences, and use of protective behavioral strategies (PBS) …

Testing An Educational Intervention To Improve Recognition And Understanding Of Emotional Manipulation In Romantic Relationships, Tiss Zaitz

Dissertations and Theses

Romantic relationships significantly impact happiness and well-being, yet rarely is it taught how to build them or recognize unhealthy relationship dynamics. This gap has profound implications, as Emotional Manipulation (EM) can have severe and lasting consequences. This study examined whether an educational intervention could improve participants' ability to recognize and understand EM in interpersonal relationships. Participants (N = 327) completed a pretest assessing recognition and comprehension of EM and were then given an answer sheet with detailed explanations to enhance understanding. A subset (n = 46) completed a posttest to measure changes in recognition and knowledge. Results showed significant improvement …

Unveiling Invisible Wounds: Experiences Of Racial Microaggressions, Racial Gaslighting, And Mental Health Among Racially And Ethnically Minoritized Adults, Supriya Pandit

Dissertations and Theses

Racial microaggressions are momentary, subtle, and often unintentional comments or behaviors that nonetheless communicate negative race-based messages towards racially and ethnically minoritized individuals. Given the accumulated and differential impact of racial microaggressions on individuals' mental health over time, it is crucial to investigate its associations with specific mental health symptoms and intrapsychic alleviating factors. To further clarify which coping strategies for racial microaggressions can be more empowering versus harmful, it is also crucial to investigate the processes and mental health consequences that unfold when individuals choose to challenge racial microaggressions, such as racial gaslighting. Racial gaslighting is an insidious interpersonal …

Living By The Sword: Religiosity And The Terrorist Subculture Of Russian Revolutionaries, 1904-1910, Gregory I. Mcevoy

Dissertations and Theses

The Marxist dictum of “religion is the opiate of the masses” has led to a prevailing assumption in scholarship that the socialist movements of the early twentieth century have been inherently atheistic. Religion is often associated as a remnant of old, antiquated society and incompatible with the claimed modernity of socialist progress. This assumption has led to overlooking the religiosity within certain radical movements and revolutionary culture at large. Scholarship on the political underground in Tsarist Russia has, thus far, perpetuated this impression. While it is the true that the Bolsheviks and Leninist Social Democrats rejected religion as obscurantist and …
