Effects Of The Self- Determined Learning Model Of Instruction On Goal Attainment And Self-Determination For Students With Autism Spectrum Disorder., Meredith M. Moates

Theses and Dissertations

Even with current transition practice and service delivery requirements mandated for students with disabilities by the Individuals with Disabilities Education Act (IDEA, 2004) participation in postsecondary education and employment for individuals with autism remains low (Shattuck et al., 2012; Newman, Wagner, Cameto, & Knokey, 2011). The purpose of this study was to determine the effects of the Self-Determined Learning Model of Instruction (SDLMI; Wehmeyer, Palmer, Agran, Mithaug, & Martin, 2000). The intervention was designed to facilitate student development, and participation in community college course settings, increase academic and vocational goal attainment and self-determined behavior while decreasing support needs. The SDLMI …

An Investigation Of Neurological Soft Signs As A Discriminating Factor Between Veterans With Post-Traumatic Stress Disorder, Mild Traumatic Brain Injury, And Co-Occurring Post-Traumatic Stress Disorder And Mild Traumatic Brain Injury, David J. Rothman

Theses and Dissertations

While multiple Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn veterans suffer from mild Traumatic Brain Injury (mTBI), Post-traumatic Stress Disorder (PTSD), and co-morbid mTBI and PTSD, there remains difficulty disentangling the specific symptoms associated with each disorder using self-report and neurocognitive assessments. We propose that neurological soft signs (NSS), which are tasks associated with general neurologic compromise, may prove useful in this regard. Based on our review of the literature we hypothesized that individuals with PTSD would present with a greater number of NSS than controls or individuals with mTBI. Further, we hypothesized a synergistic effect, such that individuals with …

The Wild Beasts, Peter Cochrane

Theses and Dissertations

The Wild Beasts springs from my desire to thank my ever-expanding queer chosen family and mentors for their strength. Working through the often violent and othering aspects of the lens and photographic histories I create floral portraits responding to each person’s being and our relationship. Using the 19th century, 8x10 large format view camera—the same used by colonialists and ethnographers to “capture” the divinity of Nature—I erect each as a traditional still life studio setup at the threshold between the natural world and that constructed by humans. These environments speak both to the character of each friend and also to …

The Puppets Look Like Flowers At Last, Evie Metz

Theses and Dissertations

The urge to uncover aspects of human condition permeates my work, from the fundamental curiosity of a child tearing apart their doll to uncover what lies within to continuing a quest in uncovering basic human urges through my puppet animated dramas and tragedies. There is a controversial line between the childlike and the adult-like that can be ambiguous, and at some times more discernible while other times less. I create handcrafted stop-frame puppet animations that explore self-conscious emotions such as embarrassment, shame, and envy within unpredictable life scenarios. These are animations about inner life, attempting to resolve conflicting elements of …

The Analgesic-Like Properties Of Alcohol In Animal Models Of Chronic Pain, Bradley Neddenriep

Theses and Dissertations

Chronic pain and excessive alcohol consumption are individually problems in our society today. Alcohol Use Disorder (AUD) affects 15.1 million adult Americans each year. Chronic pain affects over 100 million people annually in the United States. However, there is growing evidence suggesting that these two conditions can often be interrelated with chronic pain increasing consumption of alcohol, and excessive alcohol consumption increasing pain that leaves a feedback cycle trapping millions of patients in an ever worsening spiral. Large population-based studies show an association between pain and alcohol abuse, suggesting a link between increased alcohol use and reduced pain. While rodent …

Executive Functions As Moderators Of Response To Behavioral Interventions For Adolescents With Attention-Deficit/Hyperactivity Disorder, Stephen J. Molitor

Theses and Dissertations

Adolescents with Attention-Deficit/Hyperactivity Disorder (ADHD) experience significant academic impairment and multiple interventions have been developed to address common academic problems, such as difficulties with homework, organization, and planning skills. Given cost and resource constraints, research is needed on factors that mental health providers can use to select the most appropriate interventions. To date, there has been minimal research evaluating moderators of response to ADHD interventions. Further, many of the variables that have been studied do not have strong theoretical ties to the mechanisms of change invoked by the interventions. This study examined potential moderators of treatment response to two academic …

Group Decision-Making, Edward Cook

Theses and Dissertations

The present work explores improvements in group decision-making. It begins with a practical example using state-of-the-art techniques for a complex, high-risk decision. We show how these techniques can reveal a better alternative. Although we created an improved decision process, decision-makers were apt to protect their own organizations instead of the project. This tendency was reduced over the course of the decision-making process but inspired the first conceptual component of this work.

The first concept describes the “Cost of Conflict” that can arise in a group decision, using game theory to represent the non-cooperative approach and comparing the outcome to the …

Variable- And Person-Centered Approaches To Examining Construct-Relevant Multidimensionality In Writing Self-Efficacy, Morgan Debusk-Lane

Theses and Dissertations

Writing self-efficacy is a vital component to a students’ motivation and will to succeed towards writing. The measurement of writing self-efficacy over the past 40 years, despite its development, continues to largely be represented by Confirmatory Factor Analysis models that are limited due to their restricted item to factor constraints. These constraints, given prior literature and the theoretical understanding of self-efficacy, do not adequately model construct- relevant psychometric multidimensionality as a product of conceptual overlap or a hierarchical or general factor. Given this, the present study’s purpose was to examine the adapted Self-efficacy for Writing Scale (SEWS) for the presence …

Parallel Narrative: Short-Video Social Media Platforms’ Influences On Contemporary Narrative, Ruiqi Zhang

Theses and Dissertations

Through the study of Kwai, a popular short-video social media platform in China, this thesis investigates the social issues, media class divides and aesthetics specific to Kwai culture. It further proposes a strategy of artistic practice - parallel narrative - an experiment in video art production and editing techniques that explores new possibilities of narrative in video art. Integrating theoretical research on Post-Internet art and object-oriented ontology, this thesis reveals people’s ability to digest multisource information and shows how mobile technologies and open-source materials contribute to the formation of parallel narratives.

The Efficacy Of A Group Visual Art Bereavement Intervention With Older Adults, Rachel E. Weiskittle

Theses and Dissertations

Research on expressive art interventions for bereavement has burgeoned in recent years. Studies have supported their effectiveness in facilitating participants’ adjustment to loss (e.g., Rosner, Kruse, & Hagl, 2010; Uttley, 2015) and have revealed the frequency with which they are clinically implemented (Thompson & Neimeyer, 2014). Clinicians and recipients of expressive art interventions advocate for their helpfulness in grief processing (e.g., Gamino, 2015). Publications have highlighted particular visual art modules that facilitate adaptive adjustment to loss by providing avenues for self-expression, meaning making and continuing bonds with the deceased (Neimeyer, 2016), but few studies have quantitatively investigated whether they improve …

Drawing As Language, Rebecca B. Whitson

Theses and Dissertations

All too often, the “I can’t draw” sentiment is believed by both the frustrated adolescent and adult alike. This is especially evident within the school environment. This paper aims to discuss how visual art --specifically drawing-- is structured, formed and expressed as a type of language, similar to a verbal, written, or physical one. This may give hope to even the most reluctant drawer that they can learn how to draw, opening another means of communication. An individual attains fluency when they are adept at drawing through the use of expression, technical, and observational skills, through practice and motivation, and …

Young Adults With Disabilities Financial Skills And Goals: A Mixed Methods Strengths And Needs Assessment, Allison D'Aguilar

Theses and Dissertations

Young adults with disabilities face barriers that affect their financial capability and financial inclusion in the marketplace. Barriers include a lack of autonomy, skills, and opportunities. This mixed method strengths and needs assessment aimed to explain and explore the financial skills and goals of young adults with disabilities. A standardized scale captured young adults with disabilities financial skills, photovoice participatory action research documented their valued financial skills and goals, and semi-structured interviews notated parents financial aspirations and goals for their daughters and sons. The mixed methods analysis suggested young adults with disabilities underlying financial skills fell 25 percent below the …

The Role Of Mindfulness In Self-View Investment: Neural And Subjective Indicators, Hadley Rahrig

Theses and Dissertations

Self-concept is strongly influenced by beliefs about one’s personal psychological attributes, and these beliefs are held with varying degrees of confidence and consequence. Hence, it is investment in self-views of those attributes that helps to regulate and maintain stable self-concept. Self-view investment is relevant to numerous self-related functions, but high self-view investment can also contribute to maladaptive self-views. Theory suggests that mindfulness cultivates a less personal, more objective perception of one’s thoughts, emotions and behaviors, and training in mindfulness has been shown to alter self-referential processing. The current pilot study (N=21) investigates the possible role of dispositional mindfulness in two …

Longitudinal Patterns Of Depression Symptoms Among Emerging Adults, Sarah W. Clark

Theses and Dissertations

Research has suggested that depression symptoms generally decrease after late adolescence; however, there is increasing attention paid to depression symptoms among college students given the stressors unique to this time period and negative outcomes associated with depression. This study examined latent trajectories of depression symptom severity among college students. Participants were 9,889 college students who participated in the Spit for Science project (Dick et al., 2011). Growth Mixture Modeling was used to identify the presence of four subgroups of individuals with similar patterns of initial level and change in depression severity over four years of college, including Low/Minimal (55.9%), Decreasing …

Structure-Activity Relationship Studies Of Synthetic Cathinones And Related Agents, Rachel A. Davies

Theses and Dissertations

Synthetic cathinones and related agents represent an international drug abuse problem, and at the same time an important class of clinically useful compounds. Structure-activity relationship studies are needed to elucidate molecular features underlying the pharmacology of these agents. Illicit methcathinone (i.e., MCAT), the prototype of the synthetic cathinone class, exists as a racemic mixture. Though the differences in potency and target selectivity between the positional and optical isomers of synthetic cathinones and related agents have been demonstrated to have important implications for abuse and therapeutic potential, the two MCAT isomers have never been directly compared at their molecular targets: the …

Training Future Mental Health Professionals In An Evidence-Informed System Of Care, Julia R. Cox

Theses and Dissertations

High quality mental health services do not reach the youth who need them, leading to efforts to implement effective treatments more broadly. One focus of these efforts concerns training the mental health workforce, of which master’s-level social workers represent a large proportion. However, the curricula of master’s in social work (MSW) programs do not often emphasize evidence-based approaches. One possible solution is Managing and Adapting Practice (MAP; PracticeWise, LLC), a system that allows clinicians to (1) identify clinically indicated evidence-based programs by searching a growing evidence-base of randomized controlled trials (RCTs) and (2) build individualized evidence-informed treatment plans by focusing …

Perceived Impact Of Ambient Operating Room Noise By Certified Registered Nurse Anesthetists, Marianne S. Cosgrove

Theses and Dissertations

It is widely acknowledged that elevated levels of noise are commonplace in the healthcare environment, particularly in high acuity areas such as the operating room (OR). Excessive ambient noise may pose a threat to patient safety by adversely impacting provider performance and interfering with communication among perioperative care team members. With respect to the certified registered nurse anesthetist (CRNA), increased ambient OR noise may engender distractibility, diminish situation awareness and cause untoward health effects, thereby increasing the possibility for the occurrence of error and patient injury.

This research project analytically examines the perceived impact of ambient noise in the operating …

From Sunrise To Sunset: A Lifespan Approach To Understanding The Mental Health Of A Subset Of American Farmers, Janna L. Imel

Theses and Dissertations

Prior research has indicated higher risk of suicide for farmers and identified depression and anxiety as mental health concerns, though the majority of research was conducted in the 1980s-1990s. In today’s economic, social, and political climate, farmers are exposed to situations and stressors reminiscent of the 1980s Farm Crisis. An added risk is the aging workforce of farmers, as age-related conditions can make farming even riskier. This study investigated the mental health of a subset of American farmers by exploring farm-related stressors, coping mechanisms, and mental health outcomes. Dispositional mindfulness was explored as a specific coping mechanism. Participants (N …

Do Sluggish Cognitive Tempo Symptoms Improve With School-Based Adhd Interventions? Outcomes And Predictors Of Change., Zoe Smith

Theses and Dissertations

Sluggish cognitive tempo (SCT) is a construct that includes symptoms of slowness, mental confusion, excessive daydreaming, low motivation, and drowsiness/sleepiness. SCT is often co-morbid with attention-deficit/hyperactivity disorder (ADHD), and SCT symptoms are associated with significant academic and interpersonal impairment above and beyond the influence of ADHD symptoms. Despite the overlap between ADHD and SCT and associated impairments, no studies have evaluated how evidence-based psychosocial interventions for adolescents with ADHD impact symptoms of SCT. This study examined whether SCT symptoms improved in a sample of 274 young adolescents with ADHD who received either an organizational skills or a homework completion intervention. …

An Adaptation And Psychometric Evaluation Of The Teacher Attribution Measure For Early Elementary (Tam-Ee), Shannon L. Nemer

Theses and Dissertations

This study examined the reliability and validity of the Teacher Attribution Measure for Early Elementary (TAM-EE), a measure adapted from the Preschool Teaching Attributions (PTA) measure, to assess the challenging behavior attributions of early elementary teachers. Like the PTA, the TAM-EE uses a series of student-specific behavior scenarios as prompts for teachers who then rate statements aligned with dimensions of attribution theory on a 6-point scale. A sample of 41 teachers completed the TAM-EE on 79 students in grades K-3 screened for risk of emotional and behavioral disorders (EBD). Teachers also completed reports of student behavior, self-efficacy, and perceptions of …

Investigating Daily Writing Emotions, Attention Regulation, And Productivity: An Intensive Longitudinal Study, Eric Ekholm

Theses and Dissertations

Emotions pervade academic situations and influence the ways that learners think, behave, and achieve (Pekrun, 2006; Schutz & Lanehart, 2002). Writing may be a particularly emotion-laden activity, and especially so for students concentrating in fields that value writing production. However, very few studies have quantitatively investigated writers’ emotional experiences. The goal of the current study was to examine the writing-related emotions of graduate students enrolled in writing-intensive disciplines as well as how these emotions related to writers’ daily productivity and attention-regulation behaviors. To do so, the study employed a daily diary design (Gunthert & Wenze, 2012) in which participants completed …

Teacher-Child Relationships, Interactions, And Problem Behavior: A Longitudinal Analysis Examining Bi-Directional Associations, Rachel Kunemund

Theses and Dissertations

A number of preschool children engage in consistent problem behaviors that place them at-risk for developing emotional and behavioral disorders. These problem behaviors have been associated with poorer short and long-term outcomes for young children. Teacher-child relationships (i.e. conflict and closeness) and positive interactions between teachers and children may be reciprocally associated with problem behavior (e.g. teacher-child closeness reducing problem behavior). The purpose of this study was to explore the longitudinal bi-directional relations between teacher-child relationships, teacher-child interactions, and problem behavior over a single school year. Using a cross-lagged panel model, data from a larger randomized control trial of the …

The Influence Of Electronic Cigarette Heating Coil Resistance On Nicotine Delivery, Heart Rate, Subjective Effects, And Puff Topography, Marzena M. Hiler

Theses and Dissertations

Electronic cigarette (ECIG) users can manipulate several device features including liquid nicotine concentration (mg/ml) and heating coil resistance (Ohms). One class of ECIG models, called “sub-Ohm” devices, use coils with a resistance of < 1 Ohms, lower than those observed in conventional ECIGs (e.g., ≥ 1.5 Ohms). Increasing voltage or decreasing coil resistance increases device power. Given that ECIG coil resistance and liquid nicotine concentration have not been manipulated systematically and simultaneously in clinical laboratory studies, the influence of these factors on ECIG acute effects remain unclear. The primary purpose of this study was to examine the influence of coil resistance and liquid nicotine concentration on nicotine delivery, heart rate (HR), subjective effects, puff topography, and liquid consumption.

Thirty-two experienced ECIG users completed four independent laboratory sessions that differed by coil resistance (0.5Ohm or 1.5Ohm ) and liquid nicotine concentration (3 or 8 mg/ml). In each session, participants used a 4.5 V “Kanger SUBOX” loaded with 3.5 ml ECIG liquid in a 10-puff directed and 60-minute ad libitum bout. Nicotine delivery was greatest when using 8 mg+0.5Ohm combination and lowest when using the 3 mg/ml+1.5Ohm …

Axon Initial Segment Integrity In Aging And Traumatic Brain Injury, Mazen M. Gouda

Theses and Dissertations

According to the Center for Disease Control’s (CDC) report to the Congress, there are 2.2 million emergency department visits; 80,000 hospitalizations; and 50,000 deaths each year due to traumatic brain injury. Adults 65 years and older account substantially for the majority of the hospitalization and deaths. Over 70% of the traumatic brain injuries of the older adults are classified as mild to moderate; however, even with these milder injuries, older adults present with a significantly higher morbidity and mortality compared to all other age groups (LeBlanc et al., 2006). With that in mind, it seems essential to develop a deeper …

Etiological Contributions Of Genetic And Environmental Factors To Nonmedical Use Of Prescription Drugs Among Young Adults, Cassie Overstreet

Theses and Dissertations

Key variables such as trauma exposure (TE) and internalizing symptoms (e.g., posttraumatic stress disorder [PTSD]) have been shown to correlate with non-medical use of prescription drugs (NMUPD); however, the temporal associations between these phenotypes remain poorly understood. Moreover, there is a paucity of research that incorporates the influence of genetic factors in the etiology of NMUPD. Although it has been demonstrated that drug use disorders are moderately heritable, research aimed at identifying the specific genes conferring risk is virtually non-existent for NMUPD. Therefore, determining the contribution of genetic and environmental factors associated with risk is critical to understanding NMUPD. To …

Factors That Influence Mental Health Services Utilization By Children Who Have Experienced Adversity, Mary B. Stebbins

Theses and Dissertations

Adverse childhood experiences (ACEs) are linked to increased mental health problems in children, but their association with mental health services utilization is not well known. This secondary analysis used 2016 National Survey of Children’s Health data from two samples: children aged 6-17-years-old with a mental or behavioral condition in need of treatment or counseling (N = 5,723); and a subsample of children who experienced at least one ACE (n = 3,812). Multiple logistic regression and latent class analysis (LCA) were performed to examine the association between ACEs and mental health services utilization. Multiple logistic regressions also examined the …

Latent Growth Model Approach To Characterize Maternal Prenatal Dna Methylation Trajectories, Dana Lapato

Theses and Dissertations

Background. DNA methylation (DNAm) is a removable chemical modification to the DNA sequence intimately associated with genomic stability, cellular identity, and gene expression. DNAm patterning reflects joint contributions from genetic, environmental, and behavioral factors. As such, differences in DNAm patterns may explain interindividual variability in risk liability for complex traits like major depression (MD). Hundreds of significant DNAm loci have been identified using cross-sectional association studies. This dissertation builds on that foundational work to explore novel statistical approaches for longitudinal DNAm analyses. Methods. Repeated measures of genome-wide DNAm and social and environmental determinants of health were collected up to six …

The Effects Of Notch Signaling On Functional Recovery Following Traumatic Brain Injury, Jyoti Lodha

Theses and Dissertations

2.5 million people sustain a traumatic brain injury (TBI) annually in the United States. Although there is potential for functional recovery following TBI, there is no definitive treatment to improve recovery after TBI. Our lab has shown that TBI enhances an endogenous neurogenic response in the subventricular zone and hippocampus. TBI-induced neural stem cells (NSCs) can integrate into regions such as the hippocampus and olfactory bulb. Although the mechanism behind TBI-enhanced neurogenesis remains unknown, the Notch signaling pathway has been implicated as a regulator in the maintenance and survival of NSCs.

This thesis explores the effects of Notch pathway manipulation …

Exploring The Standard: A Look Into Modern Voice And Speech Curriculum, Taylor L. Bosta

Theses and Dissertations

This thesis explores the current state of voice and speech education to discover if there is a standard of learning from university to university. By examining the history of voice and speech, discovering basic skills, breaking down teaching methodologies, and taking a look at current university and conservatory acting programs, the thesis discovers there is not a standard way of teaching, but there is a standard set of skills that should be upheld when planning voice and speech curriculum.

When Empathy Only Goes So Far: Development Of A Trait Parochial Empathy Scale, Anna Maria C. Behler

Theses and Dissertations

Empathy, the ability to feel and/or understand another’s emotional state, plays a significant role in interpersonal interactions, mitigating hostility and enhancing affiliation and helping. However, empathy also biases interpersonal reactions. For example, at the group level empathy can become amplified towards members of their ingroup and blunted towards individuals in outgroups, a term called parochial empathy. Currently, no validated measures of parochial empathy at the dispositional level exist, and development of such a scale would be important to understanding the role of group-based emotions in prejudice and discrimination against outgroups. I conducted five studies to develop and validate a …
