Major Difference: An Examination Of Student Writing Performance By Major And Its Implications For Business Communication, Lucia S. Sigmar, Geraldine E. Hynes

Administrative Issues Journal

This study analyzes the writing performance levels of 352 students to determine the extent to which business students are achieving written communication competency and whether differences exist among the business majors. Although most students met or exceeded expectations in format and content on a common writing task, students were weakest in grammar and mechanics, with almost half scoring below expectations across all majors. The findings indicate no statistically significant differences in writing competency among majors. This study also suggests that business communicators can serve as “collegial consultants” in a cross-disciplinary effort to improve student writing.

Retinoids Regulate The Formation And Degradation Of Gap Junctions In Androgen-Responsive Human Prostate Cancer Cells., Linda Kelsey, Parul Katoch, Kristen E. Johnson, Surinder K. Batra, Parmender P. Mehta

Journal Articles: Biochemistry & Molecular Biology

The retinoids, the natural or synthetic derivatives of Vitamin A (retinol), are essential for the normal development of prostate and have been shown to modulate prostate cancer progression in vivo as well as to modulate growth of several prostate cancer cell lines. 9-cis-retinoic acid and all-trans-retinoic acid are the two most important metabolites of retinol. Gap junctions, formed of proteins called connexins, are ensembles of intercellular channels that permit the exchange of small growth regulatory molecules between adjoining cells. Gap junctional communication is instrumental in the control of cell growth. We examined the effect of 9-cis-retinoic acid and all-trans retinoic …

Deletion Of Foxn1 In The Thymic Medullary Epithelium Reduces Peripheral T Cell Responses To Infection And Mimics Changes Of Aging, Jianfei Guo, Yan Feng, Peter Barnes, Fang-Fang Huang, Steven Idell, Dong-Ming Su, Homayoun Shams

School of Medicine Faculty Publications and Presentations

Aging increases susceptibility to infection, in part because thymic involution culminates in reduced naïve T-lymphocyte output. Thymic epithelial cells (TECs) are critical to ensure normal maturation of thymocytes and production of peripheral T cells. The forkhead-class transcription factor, encoded by FoxN1, regulates development, differentiation, and function of TECs, both in the prenatal and postnatal thymus. We recently showed that expression of FoxN1, by keratin 14 (K14)-expressing epithelial cells is essential for maintenance of thymic medullary architecture, and deletion of FoxN1 in K14 promoter-driven TECs inhibited development of mature TECs and reduced the number of total thymocytes. These findings are reminiscent …

A Social Controversy: Autism Spectrum Disorder's Correlation To The Measles-Mumps-Rubella Vaccination, Lindsay A. Frye

Senior Honors Theses

A 1998 research study lead by Dr. Andrew Wakefield linked the measles-mumps-rubella (MMR) vaccination as a probable cause to autism spectrum disorder. This publication has started a significant debate among healthcare professionals and instigated an anti-vaccination movement within the general population. This vaccination controversy was started by parents who readily accepted Wakefield’s findings as truth and frequently would choose to withdrawal the administration of vaccinations from their children’s care plans. There has also been disapproval by healthcare professionals over Wakefield’s study since numerous research teams have been unable to replicate his findings. This disagreement surrounding the MMR vaccination is likely …

Workplace Discrimination And The Perception Of Disability, William Draper

Protein Synthesis Factors (Rf1, Rf2, Rf3, Rrf, And Tmrna) And Peptidyl-Trna Hydrolase Rescue Stalled Ribosomes At Sense Codons., Serafín Vivanco-Domínguez, José Bueno-Martínez, Gloria León-Avila, Nobuhiro Iwakura, Akira Kaji, Hideko Kaji, Gabriel Guarneros

Department of Biochemistry and Molecular Biology Faculty Papers

During translation, ribosomes stall on mRNA when the aminoacyl-tRNA to be read is not readily available. The stalled ribosomes are deleterious to the cell and should be rescued to maintain its viability. To investigate the contribution of some of the cellular translation factors on ribosome rescuing, we provoked stalling at AGA codons in mutants that affected the factors and then analyzed the accumulation of oligopeptidyl (peptides of up to 6 amino acid residues, oligopep-)-tRNA or polypeptidyl (peptides of more than 300 amino acids in length, polypep-)-tRNA associated with ribosomes. Stalling was achieved by starvation for aminoacyl-tRNA(Arg4) upon induced expression of …
