Strategies to the success of Online Course Development

Introduction Online courses provide flexible access to education from a distance. However, learners may encounter frustration and disappointment in the learning process for various reasons. Faculties might not be familiar with adult learning principles. The online course developer may have no knowledge, experience, or the skills necessary for developing online courseware. Online course development can take longer time and more resources. It can also take longer time to deliver the course. It is, therefore, important that online course development be made efficient and effective for best student learning. [See PDF for complete abstract]

Smart Classrooms: Guidelines for Educational Technology in Classroom Facility in The University of Texas System

Problem Statement: Classroom facilities developed as new construction or renovation projects for UT System institutions tend to be developed as individual, ad hoc project. There are significant opportunities for process improvement is establishing standard business processes for developing Smart Classroom, establishing design standards and referring to prototype facilities developed at other institutions.

Role of technology: Podcast in influencing respondents to receive a flu shot

Background and Problem: Studies have demonstrated that flu shots are an effective method to control flu infection. However, statistics reveal that only about 68% of people get vaccinated in the U.S. every year. We wanted to develop and evaluate an intervention to increase influenza vaccination rate.

Impact of BCR -ABL on DNA repair

The BCR-ABL fusion gene is the molecular hallmark of Philadelphia-positive leukemias. Normal Bcr is a multifunctional protein, originally localized to the cytoplasm. It has serine kinase activity and has been implicated in cellular signal transduction. Recently, it has been reported that Bcr can interact with xeroderma pigmentosum group B (XPB/ERCC3)—a nuclear protein active in UV-induced DNA repair. Two major Bcr proteins (p160 Bcr and p130Bcr) have been characterized, and our preliminary results using metabolic labeling and immunoblotting demonstrated that, while both the p160 and p130 forms of Bcr localized to the cytoplasm, the p130 form (and to a lesser extent p160) could also be found in the nucleus. Furthermore, electron microscopy confirmed the presence of Bcr in the nucleus and demonstrated that this protein associates with metaphase chromatin as well as condensed interphase heterochromatin. Since serine kinases that associate with condensed DNA are often cell cycle regulatory, these observations suggested a novel role for nuclear Bcr in cell cycle regulation and/or DNA repair. However, cell cycle synchronization analysis did not demonstrate changes in levels of Bcr throughout the cell cycle. Therefore we hypothesized that BCR serves as a DNA repair gene, and its function is altered by formation of BCR-ABL. This hypothesis was investigated using cell lines stably transfected with the BCR-ABL gene, and their parental counterparts (MBA-1 vs. M07E and Bcr-AblT1 vs. 4A2+pZAP), and several DNA repair assays: the Comet assay, a radioinimunoassay for UV-induced cyclobutane pyrimidine dimers (CPDs), and clonogenic assays. Comet assays demonstrated that, after exposure to either ultraviolet (UV)-C (0.5 to 10.0 joules m −2) or to gamma radiation (200–1000 rads) there was greater efficiency of DNA repair in the BCR-ABL-transfected cells compared to their parental controls. Furthermore, after UVC-irradiation, there was less production of CPDs, and a more rapid disappearance of these adducts in BCR-ABL-bearing cells. UV survival, as reflected by clonogenic assays, was also greater in the BCR-ABL-transfected cells. Taken together, these results indicate that, in our systems, BCR-ABL confers resistance to UVC-induced damage in cells, and increases DNA repair efficiency in response to both UVC- and gamma-irradiation. ^
