Spirituality As A Positive Youth Development Construct: A Conceptual Review, Daniel T. L. Shek

Pediatrics Faculty Publications

The concept of spirituality as a positive youth development construct is reviewed in this paper. Both broad and narrow definitions of spirituality are examined and a working definition of spirituality is proposed. Regarding theories of spirituality, different models pertinent to spiritual development and the relationship between spirituality and positive youth development are highlighted. Different ecological factors, particularly family and peer influences, were found to influence spirituality. Research on the influence of spirituality on adolescent developmental outcomes is examined. Finally, ways to promote adolescent spirituality are discussed.

Beliefs In The Future As A Positive Youth Development Construct: A Conceptual Review, Rachel C. F. Sun, Daniel T. L. Shek

Pediatrics Faculty Publications

Beliefs in the future are an internalization of hope and optimism about future outcomes. This paper reviews and compares several theories of hope and optimism and highlights the features constituting beliefs in the future. This paper points out that beliefs in the future include a series of goal-directed thoughts and motivation, such as setting up valued and attainable goals, planning pathways, and maintaining self-confidence and mastery, so as to keep adolescents engaged in the pursuit of goals. This kind of personal mastery, together with sociocultural values, family, school, and peers are the antecedents leading to beliefs in the future, which …

Pediatrics Faculty Publications

To assess the effectiveness of the Tier 1 Program of the Project P.A.T.H.S., a randomized group trial with eight waves of data collected was carried out. At the fifth year of data collection, 19 experimental schools (n = 2, 662 students) and 24 control schools (n = 3, 272 students) participated in the study. Analyses based on individual growth curve modeling showed that participants in the experimental schools displayed better positive youth development than did participants in the control schools in terms of different indicators derived from the Chinese Positive Youth Development Scale, including moral competence and behavioral competence and …

Spontaneous Recovery In Children With Expressive Language Delay, Jaimie Sierakowski

Honors Theses

By age 2, most children have an expressive vocabulary of approximately 200 words and begin to combine these words into meaningful phrases. However, some children acquire expressive language skills more slowly than others while displaying no signs of cognitive, receptive, or sensory delays. These children who experience an expressive language delay are often characterized in the literature as late talkers. Research shows that many of these children have delays early in childhood, but eventually catch up to their typically-developing peers, with no need for language intervention. Others, however, continue to experience expressive delays and. have an increased risk of developing …

Hormonal Birth Control And Abortifacient Mechanisms, Catherine M. Powell

Senior Honors Theses

Recently, there has been a growing controversy, especially among evangelicals, over whether the birth control pill might have an abortifacient mechanism that sometimes causes early chemical abortions. An understanding of this controversy necessitates a clear definition of abortion, abortifacient, pregnancy, implantation, and especially personhood. If a zygote (fertilized egg) is not a person, then it has no fundamental rights and there is essentially no debate concerning the possible link between birth control pills and abortion. There is strong indirect evidence of post-fertilization, or abortive, effects of hormonal birth control. If zygotes are people, and birth …

Evaluation Of Methods To Relieve Parental Perceptions Of Vaccine-Associated Pain And Anxiety In Children: A Pilot Study, Karlen E. (Beth) Luthy, Renea L. Beckstrand, Amy Pulsipher

Faculty Publications

Introduction: The pain and anxiety associated with vaccination is a significant reason why parents are reluctant to have their children vaccinated. Distraction methods and vapocoolant sprays may be use to modify the parent's perceptions of their child's pain and anxiety, thus encouraging parents to return for the child's next vaccination.

Methods: A convenience sample of 68 parents with children ranging in age from 2 to 12 years was selected. The parents and the child were randomly assigned to three groups: a control group, a DVD distraction group, or a vapocoolant spray group. After the child was vaccinated, parents evaluated the …

A School-Based Intervention Of Adolescent Obesity Prevention In At-Risk Youth, Leah M. Potecha

Senior Honors Theses

Obesity has become an epidemic in the United States, affecting individuals of all ages. Adolescents are particularly susceptible to obesity due to their decrease in physical activity, as well as to the greater availability of foods void of nutritional value. Adolescents’ impressionable natures and changing bodies also contribute to their increased weights. To combat the problem of obesity, many schools have implemented obesity prevention programs. Most of these programs are based on physical education and nutrition education. However, some schools have started mentorship programs, or worked with organizations that employ mentorship programs, to prevent obesity. The Lynchburg Healthy Living program …

Mandibular Symphyseal Distraction Osteogenesis (Msdo): Association With Temporomandibular Dysfunction (Tmd) Symptoms, Sheldon Bates

Theses and Dissertations

Background: Transverse mandibular discrepancies are often overlooked during orthodontic treatment. MSDO is a treatment to address this issue, but much debate exists over the long-term implications on the temporomandibular joint (TMJ). Few studies have sample sizes sufficient to draw clear conclusions about the impact of MSDO on TMJ health. Materials and Methods: This study evaluated private practice records including 49 MSDO patients and 57 traditionally-treated controls. The subjects were assessed by TMD exams that evaluated jaw pain and discomfort using visual analog scales, range of motion for opening, right and left lateral, and protrusive movements, and the presence of clenching, …

Heterotopic Ossification: Cellular Basis, Symptoms, And Treatment, Brian Wolfe

Senior Honors Theses

Heterotopic ossification (HO) is the process by which calcified bone develops in soft tissues. Because of the abnormal calcification, complications such as bone deformation, loss of range of motion, and joint immobility adversely affect patients. There are many genetic types of heterotopic ossification, namely fibrodysplasia ossificans progressiva, progressive osseous heteroplasia, and Albright hereditary osteodystrophy. However, this condition can also arise from surgery, burns, or traumatic injuries, so it is seen as an important area for research in the future. There are various treatments available such as non-steroidal anti-inflammatory drugs and radiation therapy, as well as combinations of the two. The …

Molecular Analysis Of Oligoclonal T Cells Associated With Graft-Versus-Host Disease Following Allogeneic Stem-Cell Transplantation, Kassi Avent

Theses and Dissertations

The goal of hematopoietic stem cell transplantation (HSCT) is to induce graft-versus-tumor effect (GVT), which is the recognition of and response against tumor- associated antigens (TAAs) by donor immune cells to clear the recipient of residual tumor. A complication of HSCT as a treatment for hematologic malignancies is graft-versus-host disease (GVHD), which is the recognition and reactivity of donor immune cells against healthy tissues. As of now, the differentiation between GVHD and GVT effects has been a hindrance to the development of effective therapies against GVHD. Certain T cell clones may induce both GVHD and GVT effects, making targeted therapy …

Parental Understanding Of Anesthesia Risk For Dental Treatment, Andrew Zale

Theses and Dissertations

Purpose: To determine which method of anesthesia risk presentation parents understand and prefer across their demographic variables Methods: As a cross-sectional study, questionnaires were distributed to 50 parents of patients (<7 years of age) in the VCU Pediatric Dental Clinic. Parents were asked of their own and their children’s demographics, previous dental and anesthesia experiences, and anesthesia understanding. Parents were then asked to rate the level of risk of several risk presentations and finally asked which method of risk presentation they most understood or preferred. Data analysis was performed using descriptive statistics, correlation coefficients, likelihood chi square tests, and repeated measures logistic regression. Results: There was no evidence of a differential preference due to gender (P = 0.28), age (P > .9), education (P = 0.39) or whether they incorrectly answered any risk question (P > 0.7). There was some evidence that the three types were not equally preferred (likelihood ratio chi- square = 5.31, df =2, P-value = 0.0703). The best estimate is that 60% prefer charts, 34% prefer numbers, and 36% prefer activity comparisons. There was a relationship between the average relative risk of general anesthesia and age (r …

The Effectiveness Of Visual Aids In Motivational Counseling On Oral Health Literacy, Christian Peck

Theses and Dissertations

Purpose: The purpose of this study is to determine if motivational interviewing with written/illustrated infant oral health education provided to caregivers of pediatric dental patients increases caregivers’ oral health literacy compared to verbal only motivational instruction. Methods: This is a cohort study of caregivers and their child receiving oral health anticipatory guidance utilizing motivational interviewing with and without visual aids. Caregivers (N=20) of pediatric dental patients age 0-4 that presented to the Virginia Commonwealth University School of Dentistry for a new patient exam were recruited for the study. Caregivers were randomly assigned into 2 groups: the intervention group (IG), and …

Clinical Utility Of Folate-Containing Oral Contraceptives., Zohra S Lassi, Zulfiqar Ahmed Bhutta

Woman and Child Health

Folate is a generic term for a water-soluble B-complex vitamin which plays an important role in protein synthesis and metabolism and other processes related to cell multiplication and tissue growth. Pregnant and lactating women are at increased risk of folic acid deficiency because generally their dietary folate is insufficient to meet their physiological requirements and the metabolic demands of the growing fetus. The evidence pertaining to the reduction of the risk of neural tube defects (NTDs) due to folate is so compelling that supplementation with 400 mug of folic acid to all women trying to conceive until 12 weeks of …

Electromyography (Emg) Biofeedback Training In Music Performance: Preventing And Reducing Musculoskeletal Pain In Musicians, Carolyn Yarbrough

Scripps Senior Theses

Musicians are a high-risk occupational group for musculoskeletal disorders. Often manifesting in muscle tension, pain and paresthesia, musculoskeletal disorders can drastically affect comfort, mentality and endurance while performing. This study sought to examine the effects of electromyography (EMG) biofeedback training in reducing musculoskeletal symptoms in music performance. The subjects were university-level violinists and cellists. Over a period of 2-4 weeks, all participants underwent EMG biofeedback training while performing their instrument using audio feedback. No significant results were found, but patterns of decreased muscle tension and increased performance comfort and endurance were observed.

The Effect Of Esthetic Crown Lengthening On Perceptions Of A Patient’S Attractiveness, Friendliness, Trustworthiness, Intelligence, And Self-Confidence, Samuel Lyon Malkinson

Theses and Dissertations

BACKGROUND: Smile esthetics play a major role in the perception of a person’s attractiveness, as well as other social parameters. The study aim was to see if altering the gingival display of patients would affect perceptions of the aforementioned social parameters. METHODS: Smiling photographs were taken and then digitally altered so as to lengthen the teeth and reduce the amount of gingiva. These photographs were shown to a group of senior dental students, and a group of evaluators with no formal dental training. Groups were asked to rate each picture’s attractiveness, friendliness, trustworthiness, intelligence, and self-confidence. RESULTS: The digitally altered …

Global Impacts Of Media On Tobacco Use Among Adolescents: A Comparative Analysis Of The United States And China, Katherine Theresa Lesyna

Scripps Senior Theses

Tobacco use is responsible for five million deaths annually and is one of the leading causes of preventable death worldwide. Many smokers initiate smoking behavior during adolescence. Adolescent smoking rates have been on the rise and there are a variety of different factors that contribute to the initiation of smoking behavior. While the World Health Organization (WHO) and the National Cancer Institute (NCI) have endorsed the claim that smoking in movies increases adolescents’ risk of initiating smoking, few studies have examined the impact of media on adolescent smoking in China following the expansion of transnational tobacco companies. The aim of …

An Investigation Of The Effects Of Pitocin For Labor Induction And Augmentation On Breastfeeding Success, Megan J. Lewis

Scripps Senior Theses

Rates of labor induction and augmentation have been increasing in recent decades (Glantz, 2005). According to the Listening to Mothers II survey, half of all labors in the U.S. are induced or augmented with Pitocin or other synthetic form of the hormone oxytocin (Declercq et al., 2006). Oxytocin, a naturally occurring hormone released in the pituitary gland, is involved in the stimulation of uterine contractions during labor and in the milk ejection reflex during breastfeeding, and research suggests it also has various effects on the brain, such as eliciting maternal behavior. However, studies have shown that exogenous oxytocin can interfere …

Examining Racial Differences In Sympathetic Activity Assessed During Recovery From Exercise In Obese Adolescent Females, Stacey Hall

Theses and Dissertations

Sympathetic overactivity (SO) is associated with obesity and cardiovascular disease (CVD) mortality. Black adolescents have an increased risk of obesity and CVD later in life, particularly females. PURPOSE: To evaluate differences in SO between black (BOA) and white obese female adolescents (WOA). METHODS: Sixty-one BOA (n=49, 13.7±1.6 yrs, 38.1±6.1 kg/m2) and WOA (n=12, 13.3±2.2 yrs, 34.3±4.9 kg/m2) completed a maximal graded treadmill test after which an exercise recovery index (ERI; heart rate/VO2 plateau) was calculated. RESULTS: The ERI was significantly greater in BOA compared to WOA (29.8 ± 6.4 vs. 24.1 ± 3.1, P = 0.004). Multiple linear regression modeling …

An Investigation Of The Role Of Experiential Avoidance In Posttraumatic Stress Disorder, Meaghan M. Lewis

Honors Theses

Experiential avoidance is a construct that researchers have proposed as a possible mediating factor between psychopathology and a prior history of traumatic events. Among the traumatic events investigated in the research literature, experiential avoidance has demonstrated correlations with prior experiences of sexual victimization. Posttraumatic stress disorder (PTSD) and PTSD symptoms have also been linked with incidence of sexual victimization and engaging in experiential avoidance. Another variable commonly associated with this construct is problematic alcohol consumption. The present study presumed that women with a history of sexual victimization would report high PTSD symptoms, a stronger likelihood of partaking in problem drinking, …

Analysis Of The Effects And Current Treatments Of Laminin Deficiency, Joshua Mark Reynolds

Senior Honors Theses

Laminin (LM) is a network of proteins that functions as a connective framework of most cells in the body. It is composed of multiple different subunits and therefore has many different variations. It is a trimeric protein, meaning that it is composed primarily of ⍺, β, and γ chains. The differentiation of these subunits is what gives the different variants their functions. In addition, although LM is the primary molecule in scope, the network of other connective proteins involved in LM-associated diseases will also be covered in lesser detail because molecules like dystrophin, dystroglycan, collagen, and integrin are vital to …

Accuracy Of Cone-Beam Computerized Tomography In Determining The Thickness Of The Palatal Masticatory Mucosa, Justin Hardison

Theses and Dissertations

BACKGROUND: The aim was to compare the thickness of the palatal masticatory mucosa as determined on a cone-beam computerized (CBCT) scan versus thickness determined via bone-sounding. METHODS: A total of twenty patients requiring palatal surgery participated. Thickness of the palatal tissue was measured at various points radiographically and clinically. The two techniques were compared to determine the agreement of the two measurement modalities. RESULTS: Analysis of variance determined that there was no significant difference between the two methods. A small bias of the radiographic measurement being larger was found to be statistically significant (0.09 ± 0.69mm; p <0.0001). Moreover, the tissue thickness was shown to increase as the distance from the gingival margin increased and the tissue over the molars was thinner than the tissue over the premolars. CONCLUSIONS: CBCT can be used to accurately determine the soft tissue thickness of the palatal masticatory mucosa with minimal bias.

Tgf-Beta Receptors And Alcohol Sensitivity In Drosophila, Kristyn Sennett

Theses and Dissertations

Clic proteins influence ethanol-related behavior in flies and other species and also mediate TGF-β signaling. These findings suggest that Clics and the TGF-β signaling pathway might work together to modulate behavioral responses to ethanol. I used the Drosophila model to address the hypothesis that TGF-β signaling is important for ethanol sensitivity. Ethanol sensitivity was blunted by multiple transposon insertions in the TGF-β receptor gene thickveins. Collectively, however, I found no consistent correlation between expression of thickveins and altered ethanol sensitivity in flies harboring transposons. I therefore also assessed ethanol sensitivity in flies with loss of function point mutations in thickveins. …

Mitochondrial Lysyl-Trna Synthetase Independent Import Of Trna Lysine Into Yeast Mitochondria., Naresh Babu V Sepuri, Madhavi Gorla, Michael P King

Department of Biochemistry and Molecular Biology Faculty Papers

Aminoacyl tRNA synthetases play a central role in protein synthesis by charging tRNAs with amino acids. Yeast mitochondrial lysyl tRNA synthetase (Msk1), in addition to the aminoacylation of mitochondrial tRNA, also functions as a chaperone to facilitate the import of cytosolic lysyl tRNA. In this report, we show that human mitochondrial Kars (lysyl tRNA synthetase) can complement the growth defect associated with the loss of yeast Msk1 and can additionally facilitate the in vitro import of tRNA into mitochondria. Surprisingly, the import of lysyl tRNA can occur independent of Msk1 in vivo. This suggests that an alternative mechanism is present …

The Role Of Sulfatide In The Development And Maintenance Of The Nodal And Paranodal Domains In The Peripheral Nervous System, Heather Herman

Theses and Dissertations

Sulfatide is a galactolipid and a major lipid component of the myelin sheath. Its production is catalyzed by the enzyme cerebroside sulfotransferase (CST). To determine the functions of sulfatide, the gene encoding CST was genetically disrupted resulting in mice incapable of sulfatide synthesis. Using these mice, it has been shown in the central nervous system (CNS) that sulfatide is essential for normal myelin synthesis and stability even though the onset of myelination is not impaired. Additionally, proper initial clustering of paranodal proteins and cluster maintenance of nodal proteins is impaired suggesting that paranodal domains are important for long-term node stability. …
