Bridge over troubled waters? Connecting research and pedagogy in composition and business/technical communication

Although different writing courses exist because of the different forms and purposes of writing they teach, some continuity between composition and business/technical communication would allow students to move more readily from one course to the next, while clarifying for them that writing is primarily a system of options based on analyses of situations, readers, obstacles, and goals. In this article, I call for that kind of continuity not only in pedagogy but also in research. Explaining the value of connections in pedagogy and research between composition and professional communication studies, I conclude with various questions and avenues for further research.     

Planning for the Budget-ocalypse: The Evolution of a Serials/ER Cancellation Methodology

The University of North Texas (UNT) Libraries are funded almost entirely by undergraduate student use fees. As the undergraduate enrollment has plateaued in recent years, the libraries have not been able to keep up with rising costs, resulting in a series of cuts to the materials budget totaling around $3.25 million. While some of these cuts took the form of reductions in firm orders and dissolution of approval plans, for the past three years the bulk has come from cancellations of serials and electronic resources. With each year’s cuts, the UNT Collection Development department has been forced to modify and refine their deselection process. This article will show the development of UNT’s strategy for determining cancellations using a variety of methods (overlap analysis, usage statistics, faculty input) and tools (EBSCO Usage Consolidation, Serials Solutions 360).     

Microfluidic chemical processing with on-chip washing by deterministic lateral displacement arrays with separator walls

We describe a microfluidic device for on-chip chemical processing, such as staining, and subsequent washing of cells. The paper introduces “separator walls” to increase the on-chip incubation time and to improve the quality of washing. Cells of interest are concentrated into a treatment stream of chemical reagents at the first separator wall for extended on-chip incubation without causing excess contamination at the output due to diffusion of the unreacted treatment chemicals, and then are directed to the washing stream before final collections. The second separator wall further reduces the output contamination from diffusion to the washing stream. With this approach, we demonstrate on-chip leukocyte staining with Rhodamine 6G and washing. The results suggest that other conventional biological and analytical processes could be replaced by the proposed device.     

Correlation between maximum in-shoe plantar pressures and clubhead speed in amateur golfers

Disagreements exist in the literature regarding the manner in which weight should be dynamically shared during the golf swing, both within-feet and between the back- and target-foot, to generate maximal clubhead speed. The purpose of this study was to determine whether preferential foot-loading locations underlie weight sharing by examining the correlation between clubhead speed and maximum plantar pressure (PP) distributions. Thirty-two amateur golfers with handicap indexes ranging from 2.7 to 25 performed 10 driver swings on artificial turf following a warm-up. PP distributions were recorded at 100 Hz, and clubhead speed was recorded using a ball-tracking Doppler radar system. Maximum PPs were extracted from a 2-s window approximately centred on ball contact and were regressed against clubhead speed. Significance was assessed over the entire foot surface using statistical parametric mapping (SPM), a spatially continuous technique. SPM revealed, at relatively high anatomical resolution, significant positive correlations between clubhead speed and PPs in the lateral target-foot (P < 0.05). This suggests that not only weight transfer but also weight-transfer location may be an important determinant of clubhead speed in amateur golfers.
