The Impact Of Elementary Mathematics Specialists, P. F. Campbell, N. N. Malkus

Journal of Mathematics and Science: Collaborative Explorations

Elementary Mathematics Specialists are placed in schools to construct leadership roles and to provide on-site professional development addressing mathematical content and pedagogy in order to enhance instruction and to improve student achievement. A three-year, randomized, control study found that, over time, Specialists had a significant positive impact on student achievement in Grades 3, 4, and 5. This effect on student achievement was not evident at the conclusion of the Specialist's first year of placement. It emerged as knowledgeable Specialists gained experience and as the schools' instructional and administrative staffs learned and worked together. Specialists who were highly engaged with a …

Patient Ventilator Dyssynchrony: Types, Frequency And Patterns In Critically Ill Adults, Karen Mellott

Theses and Dissertations

Patient ventilator dyssynchrony (PVD) occurs frequently, but little is known about the types, frequency and patterns of PVD for longer than 30 minutes. Deeper levels of sedation are associated with PVD. Evaluation of ventilator graphics and the ability to identify PVD should assist clinicians to optimize patient ventilator interactions and promote earlier interventions. The purpose of this study was to identify the different types, frequency and patterns of PVD in critically ill adults and determine the effect of sedation level on PVD. Thirty medical and surgical ICU adult patients were enrolled; 27 were used for analysis. Pressure/time and flow/ time …

Contributions Of Neglect Subtypes And Family History In Dsm-Iv Disorders: Findings From The Ncs-R, Leanne Heaton

Theses and Dissertations

Despite the prevalence of neglect in the child welfare system, understanding of the etiology of neglect remains limited in scope. Limitations are driven by the frequent reliance on child protective services (CPS) data which consists of identified cases and consequently, the most serious of all cases, or through a few population based studies that operationalize neglect as a homogenous phenomenon rather than as distinct subtypes. Furthermore, most studies of neglect focus on maternal deficiencies while paternal factors are largely ignored. This study is meant to address these considerations by utilizing the National Comorbidity Survey Replication (NCS-R), a broad population based …

A Post-Communist Picnic, Yi Sheng

Theses and Dissertations

Signaling the moon, packing balls of mud, carving a big sphere, cleaning with a giant unwieldy mop, playing with indigo, wrangling cardboard, setting sunflowers ablaze, playing a tune with a soda bottle, taking a walk with other people’s laundry, kindling smoke signals, weaving a bed, cracking seeds all night, listening to sleep, dressing a plant, these are some of the activities that have been incorporated into my work over the last two years. Most ideas begin in the studio and then are realized outside. Many of the tasks mentioned allow me to easily integrate into a crowd, where the project …

The Effects Of Pet Ownership On Physical Well-Being In Older Adults, Tami Pohnert

Theses and Dissertations

A large percentage of Americans own pets which may impact their health. This study examines pet ownership’s effect on well being in older adults looking at race/ethnicity. A sample of 6,565 older adults (>60) was selected from the Third National Health and Nutrition Survey. Pet owners comprised 28.3% of the sample. The theories of symbolic interaction and social integration were used to examine pet ownership’s effect on physical components of well-being. The descriptive results showed statistically significant differences in age, education, income, and marital status between pet owners and non-pet owners. Pet owners were younger, more educate, higher income …

Planning Serendipitous Liaison Outreach, John Glover, Bettina Peacemaker

VCU Libraries Faculty and Staff Presentations

College and university students, staff, and faculty are busier in 2010 than ever before. Many students work full-time in addition to school. With budget cuts, staff members are doing multiple jobs. Faculty members are being hired as fixed-term, temporary, or adjunct instructors more than ever. People do not come to the library as much as they used to, and they are often in a rush when they do.

At the same time, evolving models of reference service mean that liaison librarians are often sequestered in their offices, working elsewhere on campus, or otherwise not available when their patrons happen to …

P53 Mediated Cell Motility In H1299 Lung Cancer Cells, Mi-Yon Choi

Theses and Dissertations

Studies have shown that gain-of- function mutant p53, AKT, and NFκB promote invasion and metastasis in tumor cells. Signals transduced by AKT and p53 are integrated via negative feedback between the two pathways. Tumor derived p53 was also indicated to induce NFκB gene expression. Due to the close relationship between p53/AKT and p53/NFκB, we hypothesized that AKT and NFκB can enhance motility in cells expressing mutant p53. Effects on cell motility were determined by scratch assays. CXCL5- chemokine is also known to induce cell motility. We hypothesized that enhanced cell motility by AKT and NFκB is mediated, in part, by …

In-Vitro Metabolism And Protein Binding Of 5-Hmf, A Potential Antisickling Agent, Taghrid Obied

Theses and Dissertations

Purpose. 5-HMF is a potential antisickling agent forming a Schiff-adduct with hemoglobin (Hb). In-vitro studies were designed to identify the metabolic pathways of 5-HMF in human hepatic cytosol, to assess inter-species differences in its hepatic metabolism, and to predict in-vivo PK properties. Moreover, metabolism of 5-HMF in human RBCs was investigated. Finally, in-vitro studies were done to characterize 5-HMF binding kinetics with human Hb and albumin (HSA). Methods. NAD+ reduction was monitored at 340 nm in human hepatic cytosol for 5-HMF (26 mM) and prototypical ADH and ALDH substrates in the presence or absence of their inhibitors. Furthermore, concentration-dependency studies …

An Examination Of Factors That Influence Friendships In Young Adults From Intact And Divorced Families, Stephanie Wolf

Theses and Dissertations

Specific factors affecting young adult friendship development have been identified by the literature with little focus on which are most influential in determining friendship composition.. Hierarchical regression was used to examine such factors. Participants included 400 undergraduate Psychology students at a state university in the mid-Atlantic region. Findings indicated parental relationships were the strongest predictor of friendship quality. Parent-child bonds, conflict between parents, and emotion regulation skills best predicted levels of intimacy. Parent-child bond-especially with mother-best predicted satisfaction with friendship network as did conflict between parents. In addition, parent-child bond with mother and conflict between parents were found more important …

Theses and Dissertations

Background: Intimate partner violence (IPV) during pregnancy increases the risks of adverse outcomes for both mothers and their unborn children, including maternal and fetal death. However, more research is needed to determine if IPV increases in frequency or severity during pregnancy and to determine what the risk factors are for IPV during pregnancy. Objectives: To use data from the Chicago Women’s Health Risk Study to determine (1) if abuse is more prevalent during the pregnancy period, 2) if abuse during the pregnancy period increases in frequency or severity, 3) if pregnant women who are abused are at increased risk for …

Mindfulness, Health, Well-Being, And Patient Care Of Oncologists, Amanda Kracen

Theses and Dissertations

Demands on physicians in the workplace are growing, as are the occupational and psychosocial stressors they encounter. However, there is scant research regarding physicians, their patient care, and strategies that enhance their well-being. Mindfulness, the ability to be present in the moment, is increasingly being encouraged among healthcare workers for personal benefits and possible positive effects for patients. Thus, the present study examined (a) the health, well-being, and patient care practices of oncologists, (b) the relationship between oncologists’ mindfulness and health indicators (general health and sleep problems) with three outcomes (satisfaction with life [SWL], job satisfaction, and suboptimal patient care), …

Association Tests Of The Opioid Receptor System And Alcohol-Related Traits, Ryan Bennett

Theses and Dissertations

The opioid receptors and their endogenous ligands have long been implicated in a variety of traits including addiction, impulsive behaviors and substance dependence. Using phenotypic measurements collected from the IASPSAD, data from a latent class analysis and data from a SNP array and additional genotyping assays, association and regression tests were performed to determine the effects of common SNPs encoded in the genes of the opioid receptors and ligands on various traits relating to alcohol dependence. Although only one SNP can be reported as significant for substance dependence within alcoholics, there were a few results approaching significance that may offer …

Examining Job Satisfaction Online Adjunct Instructors': A Phenomenological Study, Shalyn Lapke

Theses and Dissertations

The study of job satisfaction for professors in the work place has been prevalent in the research for decades (COACHE, 2007). As online education grows exponentially each year (Allen & Seaman, 2006), this aspect of professorial teaching is emerging as an increasingly critical factor. Many professors that teach in the online sector have taught or are currently teaching in a face-to-face setting as well (Preziosi & Gooden, 2003). Also, many of the professors teaching online courses in the higher education arena are being hired as adjunct instructors. There is a lack of literature dealing with the satisfaction of the educator …

Lee Bontecou's Early Reliefs (1959-1965): A Critical And Contextual Analysis, Rachel Dalton

Theses and Dissertations

American artist Lee Bontecou’s oeuvre is often described as difficult to categorize or “mysterious.” Her early work—a series of metal and canvas reliefs made between 1959 and 1965—is linked to a range of stylistic associations including such radically divergent movements as assemblage, minimalism and abstract expressionism. Alternately, contemporary art historian Mona Hadler cites a series of iconographic connections between Bontecou’s reliefs and the popular culture and politics of the late 1950’s and early ‘60s. Using historian Reinhardt Koselleck’s theorization of historical time where history is constituted by an amalgamation of “temporal layers” based on particular historical perspectives, this thesis will …

Assessment Of Perceived Positive And Negative Outcomes In Risky Adolescent Dating And Peer Situations: A Descriptive Analysis Of Risk And Benefit Perception, Sarah Helms

Theses and Dissertations

Peer and dating violence perpetration and victimization are common experiences placing adolescents at-risk for maladaptive outcomes, yet little research has focused on specific problematic situations associated with these types of violence and other related risk-taking behaviors. Further, prevention programs have typically focused on changing beliefs, attitudes, and skill-deficits, with little attention to adolescents’ motivations or perceptions of costs and benefits associated with risky situations, despite support for this type of research in other health-related fields (e.g., substance abuse, behavioral medicine). The current study assessed adolescents’ perceptions of potential positive and negative outcomes associated with risky dating and peer situations, many …

Ethnic Effects On Biological, Psychosocial And Disease Care Factors In African-American Youth With Type 1 Diabetes, Priscilla Powell

Theses and Dissertations

Person-oriented and variable-oriented analyses were conducted to investigate sociodemographic differences in biological, psychosocial and disease care factors in youth with type 1 diabetes. Additionally, diabetes knowledge was evaluated as a potential mediator of SES effects on HbA1c and disease care. The sample included 349 youth, age 9-17 years (79.9% Caucasian, 71.3% lived with two biological parents, M SES = 46.24). Person-oriented t-tests confirmed commonly reported ethnic differences in HbA1c and disease care behaviors. However, variable-oriented analyses controlling for confounding sociodemographic influences showed most disease care effects attributed to ethnicity were better explained by SES. While diabetes knowledge was not a …

Examining The Mindfulness – Stress Resistance Relation: The Mediational Role Of Autonomy, Melissa Holt

Theses and Dissertations

Mindfulness – a receptive attentiveness to present experience – has been shown to promote more adaptive emotion regulation (Brown, et al. 2007) and predict autonomy - motivation to behave in a self-directed manner. In turn, autonomy has been shown to predict self-regulation (Ryan & Deci, 2000). This suggests a psychological pathway from mindfulness to autonomy to emotion regulation. To better understand the regulatory potential of a mindful disposition and the possible mediating role of autonomy in healthy adult participants (N = 69), a laboratory social evaluative threat was used called the Trier Social Stress Task (Kirschbaum, et al., 1993). Results …

Three research objectives included: 1) To explore the association between ecological protective factors and four developmental outcomes-emotional adjustment, behavioral adjustment, school performance, and educational aspiration; 2) To identify the robust protective factors; and 3) To explore the interactive relationships between risk and robust protective factors. Families (N=126) where the primary caregiver had a diagnosis of major depression and had a child …

The Genetic Epidemiology Of Purging Disorder, Anorexia Nervosa, And Obsessive Compulsive Personality Disorder, Sara Trace

Theses and Dissertations

Although a variety of factors influence the development of eating disorders, genetic factors contribute notably to their etiology. Understanding genetic factors associated with eating disorders is important, as they can influence how these disorders are recognized, researched, and treated. This dissertation included two studies addressing important questions within the fields of eating disorders and genetics; specifically, Study 1 addressed the prevalence and heritability of purging and purging disorder in a population-based sample of female twins from the United States; and Study 2 investigated the nature of the co-morbidity between anorexia nervosa and obsessive compulsive personality disorder in a population-based sample …

The Effectiveness Of Religiously Tailored Couple Counseling, Joshua Hook

Theses and Dissertations

Large numbers of couples seek treatment from religious counselors who integrate religion and spirituality (R/S) into counseling. The present dissertation reviewed the literature examining the effectiveness of R/S counseling. Several R/S treatments were helpful in treating psychological problems. There was little evidence that R/S treatments outperformed secular treatments. In Study 1, a nationwide survey was conducted that examined the beliefs of Christian counselors about integrating R/S into couple counseling. Christian counselors (N = 630) completed measures of religious commitment, experience in couple counseling, attitudes toward using religious techniques in couple counseling, and the use of theory in couple counseling. Counselors …
