Searching for alternatives to using animals in research is not a standard service currently offered by most medical research libraries. The goal of this article is to demystify this type of expert search for medical librarians and to do so using a language they know well, that of the Medical Subject Headings (MeSH) thesaurus. An attempt is made in this paper to discuss possible search strategies and to include examples of recommended approaches to searching-all in the context of the 3Rs of alternatives: Replacement, Refinement, and Reduction.  相似文献

Academic health sciences libraries can take various approaches to support the problem-based learning component of the curriculum. This article presents one such approach taken to integrate information navigation skills into the small group discussion part of the Pathophysiology course in the second year of the Dental school curriculum. Along with presenting general resources for the course, the Library Toolkit introduced an algorithmic approach to finding answers to sample clinical case questions. While elements of Evidence-Based Practice were introduced, the emphasis was on teaching students to navigate relevant resources and apply various database search techniques to find answers to the clinical problems presented.  相似文献

This paper presents a new transformation by which the stability-equation method can be applied for analysis and design of sampled-data systems. New stability criteria applicable to systems with transfer function having both real and complex coefficients are presented. Several kinds of examples are considered with computer results given.  相似文献

The aim of this study is to present spatial estimates of Phragmen-Lindelof type for a dynamical system. We show that an appropriate measure of the solutions either tends to infinity by exponential rate or decays to zero by exponential rate.  相似文献

A comparison is given of two exact methods for the analysis of nonlinear systems with stochastic input and stochastic parameters: the Taylor-Cauchy Transform method and the Volterra-Wiener Functional method. The final results check with each other. Examples are provided.  相似文献

The extent to which clients understand the nature and anticipated course of therapy is referred to as informed consent. Counseling psychologists often provide informed consent documents to enhance the education of services and for liability purposes. Professionals in numerous health care settings have evaluated the readability of their informed consent documents, but no such peer-reviewed research exists for university counseling centers. This study evaluated the informed consent documents for psychotherapy from university counseling centers using three readability formulas (Flesch-Kincaid Grade Level, Flesch Reading Ease Score, and Simple Measure of Gobbledygook [SMOG] Grading). The findings support the authors’ exploratory hypotheses that informed consent documents in university counseling centers are rated as challenging to read for college students. Recommendations and implications for practice are discussed.  相似文献

This article demonstrates how neoliberal higher education has come to play a distinct role in the global market for migrant labor, where a growing number of developing nations educate its citizens for overseas work in order to maximize future monetary remittances. Located in the Philippines, this study shows how local colleges and universities attempt to impose an ideal notion of flexibility, quickly shifting academic manpower and resources to programs that would produce the ‘right’ types of workers to address foreign labor demands. Based on qualitative interviews with Filipino college educators and students, the article then discusses how such ‘flexible’ strategies undermine the job security of college faculty and lead to the constant restructuring of physical space within university campuses. Such changes negatively affect both students and teachers.  相似文献

The current study examined relations between distinct aspects of moral functioning, and their cognitive and emotional correlates, in preschool age children. Participants were 171 typically developing 3- to 6-year-olds. Each child completed several tasks, including (a) moral tasks assessing both performance of various moral actions and evaluations of moral scenarios presented both verbally and nonverbally; and (b) non-moral tasks assessing general cognitive skill, executive functioning, theory-of-mind, and emotion recognition. Shyness and empathic concern were assessed from video acquired during participation. Results demonstrated positive associations among distinct moral actions, as well as among distinct moral evaluation tasks, but few associations between tasks assessing moral actions and moral evaluation. Empathic concern and inhibitory control each emerged as important predictors of preschoolers’ moral functioning.  相似文献
