Peer-Led Team Learning In Introductory Biology And Chemistry Courses: A Parallel Approach, A. Tenney, B. Houck

Journal of Mathematics and Science: Collaborative Explorations

Peer-Led Team Learning has been in use in Introductory Biology and Introductory Chemistry since Fall 1999 at the University of Portland. lts effect on improved conceptual understanding, retention of students, and improvement in study skills will be discussed. An ancillary, but no less important benefit in the development of interest in science teaching among the peer leaders, is also addressed.

Factors Associated With Metabolic Syndrome, Patricia Marie Selig

Theses and Dissertations

The metabolic syndrome, a clinical condition linked to diabetes and cardiovascular disease is a powerful predictor for overall mortality, and is present in more than 20% of the US. population (Ford, Giles, & Dietz, 2002). This study examines gender differences as well as other factors associated with metabolic syndrome as defined by the Adult Treatment Panel III of the National Cholesterol Education Program.

A sample of 10,134 adults between 20-64 years of age was selected from the Third National Health and Nutrition Survey. Metabolic syndrome was present in 19.6 % of this sample. An ecological model of health services was …

Vascular Cell Dysfunction And Transendothelial Migration Of Neutrophils In Preeclampsia, Courtney Elizabeth Leik

Theses and Dissertations

Oxidative stress, hyperlipidemia, neutrophil activation and endothelial cell dysfunction are characteristic of women with preeclampsia. We used in vitro experiments to test if a combination of oxidative stress and linoleic acid favors a mechanism for neutrophil transendothelial migration. We used linoleic acid because it is one of the fatty acids elevated in preeclampsia and the precursor for arachidonic acid and its inflammatory metabolites. For these studies, we developed a methodology for isolating and Culturing human vascular smooth muscle cells from placental chorionic plate arteries. Treatment of these cells with an oxidizing solution enriched with linoleic acid, but neither component alone, …

Mechanisms Underlying Protection Against Rt-2 Gliomagenesis In Rat Brain Utilizing Primary And Secondary Vaccination, Andrea M. Lister

Theses and Dissertations

Primary brain tumor affects some 18,000 adults in the United States each year (Silverberg et al., 1990; Merchant et al., 1997) and over 30% are high-grade anaplastic astrocytoma or glioblastoma multiforme (GBM) (Parney et al., 1997). According to Kruse et al., 1989, the treatment of patients with recurrent or persistent high-grade gliomas represents a major therapeutic challenge. The use of conventional therapy consisting of surgery, followed by radiation therapy and chemotherapy for gliomas, has been relatively ineffective (Jaecle et al., 1994) despite the fact that these therapies are cytoreductive in nature (Black, 1991). Most malignancies will recur locally but may …

Afm, Cafm, And Efm Studies Of The Gan System, John C. Dickinson

Theses and Dissertations

This thesis discusses a variety of techniques based on the atomic force microscope (AFM), and their application to the GaN materials system. In particular, the local conductivity and contact potential of surfaces have been measured using the techniques of Conductive AFM (CAFM) and Surface Potential Electric Force Microscopy (SPEFM), respectively. CAFM studies of GaN surfaces have revealed that prismatic planes around islands and pits on surfaces can lead to enhanced conductivity, which may be related to leakage problems in device applications. With regard to SP-EFM work, the change in surface potential associated with inversion domains on Ga-polar GaN has been …

Moments Of Trust: Sibling Responses To The Disclosure Of A Sister's Lesbian Identity, Ryan Walter Mckee

Theses and Dissertations

To better understand the responses of siblings to the disclosure of a sister's lesbian identity, eight pairs of siblings, each consisting of one lesbian participant and one of her siblings, were interviewed. Both lesbian and sibling participants were asked to discuss family relationships before disclosure (coming out), the actual disclosure, sibling reactions, parental reactions, and family relationships since disclosure. Notable results include "closeness" in sibling relationships and high levels of "trust" as strong predictors of supportive sibling responses. Siblings were also found to take on the role of confidant and counselor for their parents as they negotiated their daughters' newly-disclosed …

The Bond Strength Of Adhesive Resin Cement: Time Differential Between Cementation And Finishing Of Cast Dowel-Cores, Purnima Joan Shahani

Theses and Dissertations

THE BOND STREGTH OF ADHESIVE RESIN CEMENT: TIME DIFFERENTIAL BETWEEN CEMENTATION AND FINISHING OF CAST DOWEL-CORES By Purnima Joan Shahani, D.D.S., M.S.A Thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Dentistry at Virginia Commonwealth University.Virginia Commonwealth University, 2003Major Director: Peter C. Moon, M.S., PhDDirector of VCU Dental Biomaterials LaboratoryThis study compared the retention of cast dowel-cores cemented with Panavia® 21 subjected to immediate versus delayed high-speed finishing. Conventionally, finishing is delayed for 24 hours to one week to allow for optimal setting and ultimate strength of the cement. Forty-five recently extracted human …

Normal Mixture Models For Gene Cluster Identification In Two Dimensional Microarray Data, Eric Scott Harvey

Theses and Dissertations

This dissertation focuses on methodology specific to microarray data analyses that organize the data in preliminary steps and proposes a cluster analysis method which improves the interpretability of the cluster results. Cluster analysis of microarray data allows samples with similar gene expression values to be discovered and may serve as a useful diagnostic tool. Since microarray data is inherently noisy, data preprocessing steps including smoothing and filtering are discussed. Comparing the results of different clustering methods is complicated by the arbitrariness of the cluster labels. Methods for re-labeling clusters to assess the agreement between the results of different clustering techniques …
