The librarians of the Health Sciences Library worked with the director of the Primary Care Clerkship to reinforce the principles of Evidence-Based Medicine (EBM) searching, taught during the first two years of medical school, through an intensive workshop. The purpose of the program was to ensure that students apply EBM principles in a timely and effective manner in clinical situations. Working in teams led by a resident and librarian, students researched real cases and then evaluated the effectiveness of their approach to the problems. This paper outlines the rationale for the team approach, reviews the administration of a computer-based workshop, and discusses the evaluation process. Evaluation focused on both the current workshop and its implications for the informatics program presented to students during years one and two. 相似文献

Efficient lysis is critical when analyzing single cells in microfluidic droplets, but existing methods utilize detergents that can interfere with the assays to be performed. We demonstrate robust cell lysis without the use of detergents or other chemicals. In our method, cells are exposed to electric field immediately before encapsulation in droplets, resulting in cell lysis. We characterize lysis efficiency as a function of control parameters and demonstrate compatibility with enzymatic assays by measuring the catalysis of β-glucosidase, an important cellulase used in the conversion of biomass to biofuel. Our method enables assays in microfluidic droplets that are incompatible with detergents. 相似文献

The use of formal specification in software development is becoming increasingly prevalent. The Z nota-tion is a formal method, a language, and a style for expressing formal specification of software systems. This paperpresents a part of the specification work on a hotel guestroom reservation system. 相似文献

We present a method to add reagent to microfluidic droplets by enveloping them as a double emulsions in reagent-filled droplets and then rupturing them with an electric field. When the double emulsions rupture, they release their contents into the enveloping droplets, ensuring mixing with reagent while limiting cross-droplet contamination. 相似文献

Funds made available at the close of the 2010–11 fiscal year allowed purchase of the EBSCO Discovery Service (EDS) for a year-long trial. The appeal of this web-scale discovery product that offers a Google-like interface to library resources was counter-balanced by concerns about quality of search results in an academic health science setting and the challenge of configuring an interface that serves the needs of a diverse group of library users. After initial configuration, usability testing with library users revealed the need for further work before general release. Of greatest concern were continuing issues with the relevance of items retrieved, appropriateness of system-supplied facet terms, and user difficulties with navigating the interface. EBSCO has worked with the library to better understand and identify problems and solutions. External roll-out to users occurred in June 2012. 相似文献

This research work presents a Bayesian Performance Prediction Model that was created in order to determine the strength of personality traits in predicting the level of mathematics performance of high school students in Addis Ababa. It is an automated tool that can be used to collect information from students for the purpose of effective group composition. During the study, attributes that affect performance in mathematics were identified and the sources of the data were analysed. Based on collected data, a predictive tool was developed and a 70.9% prediction accuracy was achieved vis‐à‐vis actual exam results. Further work and modification of the prediction model increased the level of prediction accuracy to 78.4%. The findings of this research provide an insight into the possible applications of uncertainty management techniques, particularly to address some of the conflicting results relating to the significance of factors affecting student performance of the mathematics subject. This has implications regarding methods of grouping learners for optimum performance. Future research may include a deeper exploration of factors related to performance and more specifically how the Bayesian predictive model can be incorporated for effective group formation. Furthermore, researchers might be able to extend the application of similar performance prediction models for other academic subjects. 相似文献

This essay makes the case that Barbara Park’s picture book MA! There’s Nothing to Do Here!: A Word from Your Baby-in-Waiting (2008) adds another equal-parts absurdist and alarming item to the ever-growing responsibilities of expecting mothers: ensuring that their fetus is entertained. The messages that Park’s narrative sends about fetal needs, however, have implications that extend beyond individual mothers; they also encompass larger societal issues concerning the origins of human life, the embryonic capacity for discomfort, and the existence of “fetal children.” Given the way in which MA! There’s Nothing to Do Here! ascribes thoughts and emotions to an unborn baby, the narrative engages with current highly-politicized questions about the rights of the unborn and the debate over personhood. The fetus in Park’s text may be ostensibly complaining about being bored in the womb, but he is making a far more powerful, if tacit, argument for life beginning before birth. 相似文献
