College Students' Development Of Civic Commitment: Experiences Of Service Learning Across The College Years, Kailee Ann Brickner-Mcdonald

Graduate College Dissertations and Theses

Functional democracy in a just society requires citizens who are complex thinkers and skilled, caring leaders. This study examines how undergraduate college students become committed citizens, the kind demanded by our changing world. In particular, it addresses the developmental and experiential factors that influence students' journeys of commitment to the public good, and how students understand their lived experiences integrating these diverse influences. Framed by my constructivist epistemology, I used the qualitative tradition of narrative inquiry to address these questions. I interviewed twelve highly engaged students about their experiences in diverse community-based work and learning over four years of college. …

Comparing The Smoking Topography Of Usual Brand Cigarettes In Pregnant And Non-Pregnant Smokers, Cecilia Louise Bergeria

Graduate College Dissertations and Theses

Introduction: Most pregnant smokers report abruptly reducing their cigarettes per day (CPD) by ~50% shortly after learning of pregnancy and of making further smaller reductions over the remainder of their pregnancy. Laboratory and naturalistic studies with non-pregnant smokers have found that these types of reductions often lead to changes in smoking topography (i.e., changes in smoking intensity to maintain a desired blood-nicotine level). 19, 20 If pregnant women engage in compensatory smoking, they may expose themselves and their offspring to the same level of toxicants despite reporting reductions in CPD.

Methods: Pregnant and non-pregnant female smokers (n = 17 and …

Multidimenional Assessment Of Parenting Across Three Developmental Stages, Justin Parent

Graduate College Dissertations and Theses

BACKGROUND: The primary aim of the current study was to create a new measure of parenting practices, constituted by items from already established measures in order to advance the measurement of parenting practices in clinical and research settings. The current study utilized five stages designed to select only the best parenting items, establish a factor structure consisting of positive and negative dimensions of parenting, meaningfully consider child developmental stage, ensure strong psychometric properties, and provide initial evidence for the validity of the final measure.

METHODS: A total of 1,790 parents (44% fathers) were recruited online through Amazon's Mechanical Turk for …

The Moderating Role Of Rsa Baseline, Reactivity, And Recovery In The Link Between Parental Socialization Of Emotion Regulation And Children's Internalizing Symptoms, Wesley Sanders

Graduate College Dissertations and Theses

In this study I examined the moderating effect of three profiles of respiratory sinus arrhythmia (RSA at baseline, in response to a stressor, and in recovery from a stressor) on the relationship between parental emotion socialization during an emotion-related discussion and parental report of child internalizing symptoms 6 months later. Parents were observed during an emotion discussion task and coded for their use of emotion encouragement and general positive involvement. A total of 65 families with children between the ages of eight and ten years old completed this task while RSA scores were obtained from children during baseline, task, and …

Transdermal Testosterone For Menopause-Related Hyposexual Desire Disorder: Current Guidelines And Provider Perceptions, Knowledge, And Practice, Kelly Christine White

Graduate College Dissertations and Theses

Hypoactive sexual desire or low libido in women are collectively referred to as hypoactive sexual desire disorder (HSDD). HSDD is estimated to occur in 10% to 15% of adult women. HSDD is likely the most common female sexual dysfunction (FSD) in menopausal women. The hallmark of the diagnosis is personal distress and interpersonal difficulties resulting from low sex drive. Most women will not seek help for this problem. Studies have suggested that primary care providers and gynecologic healthcare providers report not feeling qualified to treat patients with sexual dysfunction, especially HSDD. Testosterone, specifically transdermal testosterone, has been suggested to play …

Making I-Contact: Fostering Shared, In-The-Moment Subjective Experiences, Mark Huneke

Graduate College Dissertations and Theses

Numerous research studies have offered evidence that I-sharing (perceived subjective similarity) facilitates interpersonal connection (e.g. Huneke & Pinel, 2016; Pinel, Long, Landau, Alexander, & Pyszczynski, 2006; Pinel & Long, 2012). Despite this research, no interventions currently exist to foster I-sharing between individuals, thereby leaving interventionists and others unable to utilize I-sharing to nurture authentic connections. The current dissertation takes an important step in the direction of developing usable interventions based on I-sharing research. Specifically, I examine the effectiveness of a technique designed to foster I-sharing genuinely between individuals. Building on I-sharing theory, which specifies that people most confidently believe that …

Transitions In Subtypes Of Withdrawn Behavior From Childhood To Adolescence: The Role Of Sports Participation, Meghan Conboy Schreck

Graduate College Dissertations and Theses

Withdrawn behavior broadly describes individuals who are isolated from their peer group. Though not a clinical disorder, withdrawn behavior is a construct involved in many psychological problems, and it is likely the behavioral manifestation of distinct motivations and developmental processes. Additionally, withdrawn behavior is often used interchangeably with other psychological constructs, including shyness, social disinterest, and peer exclusion, making accurate classification difficult. In an effort to better understand the classification and developmental course of withdrawn behavior in youth, the current study used latent class analysis (LCA) and latent transition analysis (LTA) to identify distinct subclasses of withdrawn youth and to …

Predictive Modeling Of Adolescent Cannabis Use From Multimodal Data, Philip Spechler

Graduate College Dissertations and Theses

Predicting teenage drug use is key to understanding the etiology of substance abuse. However, classic predictive modeling procedures are prone to overfitting and fail to generalize to independent observations. To mitigate these concerns, cross-validated logistic regression with elastic-net regularization was used to predict cannabis use by age 16 from a large sample of fourteen year olds (N=1,319). High-dimensional data (p = 2,413) including parent and child psychometric data, child structural and functional MRI data, and genetic data (candidate single-nucleotide polymorphisms, "SNPs") collected at age 14 were used to predict the initiation of cannabis use (minimum six occasions) by age 16. …

Relational, Indirect, And Social Aggression: Measure Development For Emerging Adults, Nicole Lafko Breslend

Graduate College Dissertations and Theses

Research indicates that relational aggression, social aggression, and indirect aggression are important predictors and outcomes of social development (Archer & Coyne, 2005). Socially, indirectly, and relationally aggressive behaviors are utilized in order to harm an individual's social status, relationships, and/or social resources (Archer, & Coyne, 2005), but scholars disagree about the extent of the similarities and differences between these subtypes. Previous efforts to understand the distinction between these subtypes of aggression have been limited by how these behaviors have been operationalized and studied. The primary aim of the current study was to develop a self-report measure of these aggressive behaviors …

Protein Kinase Mzeta (Pkm-Ζ) Regulates Kv1.2 Dependent Cerebellar Eyeblink Classical Conditioning, Kutibh Chihabi

Graduate College Dissertations and Theses

Learning and memory has been a topic that has captured the attention of the scientific and public communities since the dawn of scientific discovery. Without the faculty of memory, mammals cannot experience nor function in the world; among homosapiens specifically, language, relationships, and personal identity cannot be developed (Eysenck, 2012). After all, some philosophers such as John Locke argued we are nothing but a collection of past memories in which we have developed and improved upon (Nimbalkar, 2011).

Understanding the cellular mechanisms behind learning, and the subsequent formation of memory, has been a topic that has garnered scientific interest for …

The Influence Of Adverse Childhood Experiences, Families, Neighborhoods, And School Environments On Cognitive Outcomes Among Schoolchildren, Mark William Olofson

Graduate College Dissertations and Theses

Schools, families, and neighborhoods can support the development of happy, healthy children and adolescents. However, a majority of children in the United States also experience adversity in their early lives that can have deleterious effects on their cognitive and socioemotional development. Measuring and modeling early adversity is fundamental to understanding development as it occurs through interactions with schools, families and neighborhoods. As outlined by Bronfenbrenner's bioecological model of human development, proximal and distal forces shape development, and cannot be isolated when relating measures of the developmental context to outcomes for individuals. For schools and other social programs to support students …

Comparing The Effects Of Menthol Status On The Behavioral Pharmacology Of Smoking Reduced Nicotine Content Cigarettes, Danielle Davis

Graduate College Dissertations and Theses

Introduction: An active area of tobacco regulatory science research focuses on examining the effects of varying the nicotine content of cigarettes as part of a potential national policy to lower their nicotine content levels to reduce addiction potential. The present study examines differences in the behavioral effects of reduced nicotine content cigarettes related to their menthol status. Menthol is the only cigarette flavoring that is still legally permissible according to Food and Drug administration regulations.

Methods: Participants were 26 current adult smokers from three populations especially vulnerable to tobacco use and addiction (economically disadvantaged women, opioid-dependent individuals, individuals with affective …

Cues Associated With Alternative Reinforcement Can Attenuate Resurgence Of An Extinguished Instrumental Response, Sydney Trask

Graduate College Dissertations and Theses

In resurgence, a target behavior (R1) is acquired in an initial phase and extinguished in a second phase while an alternative behavior (R2) is reinforced. When reinforcement for the second response is removed, however, R1 behavior returns or “resurges.” The resurgence paradigm may have implications for understanding relapse after behavioral interventions in humans such as contingency management, or CM, in which (for example) drug users can earn vouchers contingent upon drug abstinence. The present experiments examined the effectiveness of a putative retrieval cue for treatment in attenuating the resurgence effects and determined the likely mechanism by which this cue functions. …

The Impact Of Stigma On The Mental Health Of Resettled African And Asian Refugees, Victoria M. Baptiste

Graduate College Dissertations and Theses

The global refugee crisis worsens day-by-day, with millions of refugees forced to seek safe haven abroad. Pre-migration trauma exposure contributes to disproportionately higher rates of psychopathology, especially among torture survivors and women. The extant literature has largely focused on the effects of pre-migration factors; however, increasingly, researchers recognize the critical impact of post-migration living difficulties (PMLD) in exacerbating refugee mental health. One example of a PMLD is stigma, defined as a socially devalued attribute (e.g., minority race, ethnicity, sex). A robust literature documents the deleterious effects of stigma on psychological functioning, but few studies of refugees have explored stigma, which …

The Impact Of Depression On Treatment Adherence And Cardiorespiratory Fitness In Cardiac Rehabilitation, Sheau-Yan Ho

Graduate College Dissertations and Theses

Major depression and coronary heart disease are two strongly linked, major causes of death and disability. After an acute coronary event, many patients are referred to cardiac rehabilitation (CR), a medically supervised exercise intervention and lifestyle training program. Depression may partially account for poor CR adherence and resulting cardiovascular problems in patients with a history of heart disease; however, underlying mechanisms through which depression impacts cardiac functioning are not well understood. The current project tests a theoretical model in which CR adherence (i.e., number of CR sessions attended) mediates the relation between baseline depression and cardiorespiratory fitness after CR. A …

The Psychopathic Personality: Measurement, Variants, And Utility Of The Construct, Melissa L. Paiva-Salisbury

Graduate College Dissertations and Theses

Antisocial behaviors (AB), which place an enormous burden on society, are committed by a heterogeneous population, including psychopaths (Poythress et al., 2010). Psychopathy denotes a more serious and entrenched pattern of AB (Hare, 1996) and appears to be a heterogeneous construct as well. In fact, Primary and Secondary psychopathic variants are consistently identified in a variety of samples using person-centered analysis (Drislane et al., 2014; Gill & Stickle, 2016). Both Reinforcement Sensitivity Theory (Gray & McNaughton, 2000) and the Triarchic Model of Psychopathy (Patrick, Fowles, & Krueger, 2009) provide useful frameworks to understand the etiology of the psychopathic variants. The …

Renewal In The Context Of Stress: A Potential Mechanism Of Stress-Induced Reinstatement, Scott Timothy Schepers

Graduate College Dissertations and Theses

In the animal laboratory, stressors can produce the relapse of drug-seeking behaviors after the behavior has been inhibited by extinction. This type of relapse has been called stress-induced reinstatement, and it models the relapse that is commonly reported in human populations. Interestingly, in the laboratory, stress does not typically reinstate extinguished behaviors that have been reinforced by food. One account of the discrepancy is that drugs of abuse may induce stress; therefore, when organisms learn to respond for drugs, they might learn to make the response in the “context” of stress. If so, then stress-induced reinstatement may be better described …
