An Examination Of The Technical And Relational Hypotheses Of Motivational Interviewing In A Sample Of African American Adolescent Girls Seeking Obesity Treatment, Rachel L. Boutte

Theses and Dissertations

Adolescent obesity has increased exponentially over the past three decades in the United States. In response, behavioral interventions have been developed and implemented to address this epidemic; however, treatment adherence is often suboptimal. Motivational interviewing (MI) is a directive, person centered approach to reducing patient ambivalence about change, which has been shown to increase engagement in obesity interventions. The current study investigated the underlying process of MI by exploring two different, but related pathways that explain how change happens (e.g., the technical and relational hypotheses) in the context of a multidisciplinary obesity intervention with African American adolescent girls (N …

Trabecular Bone Microarchitecture In Association With Systemic And Local Factors As Potential Predictors Of Implant Failure, Diego A. Camacho Dmd

Theses and Dissertations

Clinicians have described the success rates of dental implants. The use of implants is projected to increase in the future. With a 5-10% failure rate, it is unclear the exact factors that are associated with implant failures. To improve upon these success rates, it is critical to understand parameters associated with implant failure including: periodontitis, peri-implantitis, systemic diseases, site preparation, dental history of the implant site, bone quality, materials, occlusion, and treatment timelines. While bone quality is associated with failure, objective measures to assess bone quality and characteristics are scarce. Therefore, the aim of this study is to determine whether …

Acute And Chronic Effects Of Inhalants In Intracranial Self-Stimulation, Matthew Tracy

Theses and Dissertations

Inhalants are a loosely defined diverse group of volatile substances which people abuse. Despite widespread misuse of inhalants, there are limited preclinical methods available to study the reinforcement-like properties of inhalants. One procedure which has demonstrated substantial promise as a tool to investigate inhalant pharmacology is the intracranial self-stimulation (ICSS) procedure. ICSS utilizes pulses of electrical stimulation to the mesolimbic reward pathway to serve as a temporally defined and controlled operant reinforcer with a highly adjustable efficacy. The first aim of the project was to characterize the effects of commonly abused inhalants: including toluene, trichloroethane, nitrous oxide, isoflurane and R134a …

Longitudinal Relations Between Parental And Peer Support For Violent And Nonviolent Responses To Conflict And Early Adolescent Dating Aggression, Rachel C. Garthe

Theses and Dissertations

High prevalence and the negative legal, health, and psychological consequences of adolescent dating aggression underscore the need to identify risk and protective processes associated with this type of aggression. Studying dating aggression in early adolescence is important, as this is the developmental time frame when most youth are establishing attitudes, beliefs, and norms for dating behaviors. The current study investigated longitudinal associations between perceived parental and peer support for violent and nonviolent responses to conflict and dating aggression perpetration among middle school students. Participants included 1,399 adolescents (52% female) in the sixth (n = 466), seventh (n = …

Hidden In Plain Sight: Image, Text, And Social Commentary In Victor Ekpuk's Cartoons For The Daily Times Of Nigeria, 1989-1998, Kaleb W. Jewell

Theses and Dissertations

This thesis provides an analysis of the cartoons produced by Victor Ekpuk for The Daily Times newspaper of Nigeria from 1989 through 1998 and the artist’s use of ancient nsibidi script to “hide in plain sight” his social commentaries on sociopolitical and economic issues in Nigeria. Victor Ekpuk’s original cartoons within the permanent collection of the Smithsonian Institution’s National Museum of African Art are examined in the context of indigenous masking practices and other indirect methods employed by indigenous comedians to protect themselves. Moreover, the cartoons’ use of caricature and their nsibidi scripts within are argued to provide a connotative …

Sciatic Peripheral Nerve Blockade For Pain Control Following Hamstring Autograft Harvest In Adolescents: A Comparison Of Two Techniques, James Furstein

Theses and Dissertations

Anterior cruciate ligament reconstruction utilizing a hamstring autograft is a surgical technique that has gained popularity among orthopedic surgeons caring for adolescent patients. While utilization of a hamstring autograft is a revered technique, harvest of the hamstring yields significant pain. Sciatic peripheral nerve blockade has proven to reliably provide analgesia at the hamstring donor site. Single-injection sciatic peripheral nerve blockade is considered a basic and effective technique, making its use following anterior cruciate ligament reconstruction standard practice in many institutions. The duration of action of a single-injection sciatic peripheral nerve blockade may fail to outlast the pain arising from the …

Loneliness, Cynical Hostility, And Cognitive Decline In Americans Above Age 50, Sarah C. Griffin

Theses and Dissertations

Background. Research identifies isolation (being alone) as a risk factor for cognitive decline— yet it is possible that subjective dimensions of isolation are more critical. Potential risk factors are loneliness (the distress stemming from feeling alone) and cynical hostility (an attitude of distrust and cynicism). The present study examined the relationship between these factors and cognitive functioning and decline.

Methods. Data came from the Health and Retirement Study, a nationally representative longitudinal study of US adults over 50. Loneliness was measured using the Hughes Loneliness Scale; cynical hostility was measured using items from the Cook-Medley Hostility Inventory. Cognitive functioning was …

Exploring The Influence Of Socioeconomic Status On The Executive Function And Theory Of Mind Skills Of Preschoolers, Andrea Molzhon

Theses and Dissertations

Executive function (EF) and theory of mind (ToM) skills develop rapidly during the preschool years and have been found to directly and indirectly contribute to school readiness. Evidence indicates that EF may influence ToM development, though this relation may not be consistent across children from different backgrounds. Additionally, socioeconomic status (SES) has been shown to affect preschoolers’ EF, while the literature is mixed regarding the effects – if any – that SES may have on ToM development. Though the relation between EF and ToM appears robust across the literature, the possible effects of SES on this relation have yet to …

Characterization Of Poly(Dimethylsiloxane) Blends And Fabrication Of Soft Micropillar Arrays For Force Detection, Thomas J. Petet Jr

Theses and Dissertations

Diseases involving fibrosis cause tens of thousands of deaths per year in the US alone. These diseases are characterized by a large amount of extracellular matrix, causing stiff abnormal tissues that may not function correctly. To take steps towards curing these diseases, a fundamental understanding of how cells interact with their substrate and how mechanical forces alter signaling pathways is vital. Studying the mechanobiology of cells and the interaction between a cell and its extracellular matrix can help explain the mechanisms behind stem cell differentiation, cell migration, and metastasis. Due to the correlation between force, extracellular matrix assembly, and substrate …

Longitudinal Relations Between Parental Messages Supporting Fighting And Aggressive Behavior In Early Adolescence: The Moderating Role Of Positive Parenting Practices, Megan M. Carlson

Theses and Dissertations

The prevalence of physical aggression increases during adolescence and is associated with negative health outcomes. It is important to identify risk and protective processes for adolescent aggression in the context of the parent-adolescent relationship. The current study examined the potential moderating role of positive parenting at Wave 1 on relations between perceived parental messages supporting fighting at Wave 1 and adolescent aggression based on parent- and student-report at Wave 2. Participants included a sample of 537 adolescents and their primary caregivers, recruited from four sites in the U.S. No significant moderating effects were found. However, parental messages supporting fighting were …

Adjustment Profiles Among Youth In Diverse Cultural Contexts: Individual, Family, And Contextual Influences, Alicia Borre

Theses and Dissertations

Recent literature has noted that not all youth who experience adverse circumstances (e.g. poverty, exposure to violence, maltreatment) end up displaying expected unfavorable outcomes (e.g. academic failure, depression, drug dependence); in fact, some youth display “resilience,” broadly understood as adaptive functioning in the face of adversity (Luthar, Cicchetti, & Becker, 2000). Overall, research on resilience has offered a new approach to the study of at-risk populations, emphasizing the study of strengths, processes, and mechanisms among individuals and communities that may favor positive adaptation, rather than emphasizing deficits among those experiencing adversity (Schoon, 2012). Although resilience research has come a long …

The Netflix Effect And Defining Binge-Watching, Brenna C. Davis

UROP Posters

With the accessibility of television programs provided by popular streaming platforms, like Netflix, consumers can watch episodes or seasons of their favorite programming in just one sitting. This new practice of watching television has been referred to as binge-watching, and is defined by Netflix as watching two to six episodes of the same show in one sitting. Netflix’s definition is the most widely used definition of binge-watching, but does not account for the varying lengths of episodes for the different types of programming. There is a lack of standardization in what constitutes a television binge, like the standards that exist …

Examining The Psychological Adjustments Of Neurotypical Siblings Of Individuals With Autism Spectrum Disorder (Asd) And Determining The Efficiency Of Support Groups, Swathi Deo Sambatha

UROP Posters

Neurotypical siblings of individuals with behavioral disorders are reported to have complex, complicated psychological adjustments that vary significantly due to a multitude of sociodemographic factors. In addition, these children are at risk of mental health disorders and negative psychological symptoms. Support groups or extensive social support are known to increase intra-communication and create better sibling dynamics between the neurotypical and autistic siblings. This paper investigates such complications to the psychological adjustment of neurotypical siblings of individuals with autism spectrum disorder (ASD) and determines the implications of the utilization of support groups/social support. The analyzed trends and reportings of multiple studies …

The Relation Between Infant Construction Strategy And Language Development In Toddlers, Gullnar Syed, Emily C. Marcinowski, Stacey C. Dusing, George F. Michel, Eliza L. Nelson

UROP Posters

Infants learn from interaction with physical objects in their environments. Object construction, or merging individual objects into a single structure, has been linked previously to language. Items and toys can be structured and combined with similarity to word combinations (Greenfield, 1991). Infants initially combine 2 objects and then graduate on to combine 3 pieces or more. Words are put together in comparable ways, with each word corresponding to an object, and a sentence corresponding to a single structure. The purpose of this project is to explore how construction ability in infants affects language ability in toddlers. We hypothesize that the …

"Black People Don't Tip": Racism In The Restaurant Industry, Hortance E. Houngbeke

UROP Posters

Due to discrimination, waiters are less likely to provide good customer service to their black dinners solely based on the assumption that they are poor tippers. The theory of discrimination is the foundation of this observational study where attentiveness is measured to reflect waiters’ avoidance of African American diners. Assuming waiters start with their preconceived notions about Black customers, this research will use the critical race theory to determine if waiters are less attentive to African American diners. To further understand the subtle discriminatory behavior of waiters toward African Americans, this study analyzes observational data from a sample of waiters …

Promoting Prosocial Responsiveness Across Racial Divides Through Mindfulness, Chris J. Wall, Paul E. Plonski, Daniel R. Berry, Kirk W. Brown

UROP Posters

In interracial and other intergroup interactions, prosocial emotions and actions are often undermined (Cikara & van Bavel, 2014). Perceiving psychological separateness between “us” and “them” – which is often an automatic, unintentional process – is psychological kindling for lower prosocial responsiveness that leads to prejudice, discrimination, aggressive conflict (Cikara, 2015). Recent research has shown that mindfulness, an open and unconditional attention to one’s present experiences, is associated with decreased automaticity and racial bias (Kang, Gruber, & Gray, 2013; Lueke & Gibson, 2014), barriers that hinder prosocial responsiveness (Trautwien, Schmidt, & Naranjo, 2014). Two experiments investigated whether brief mindfulness training promoted …
