Basic measurements and applications of six selected general but critical operational performance‐based indicators—effectiveness, efficiency, productivity, profitability, return on investment, and benefit‐cost ratio—are presented. With each measurement, goals and potential impact are explored. Errors, risks, limitations to measurements, and a final check for validity, applicability, accountability, and usability of these measurements are discussed. This article provides a simple, practical guide to performance measurement for organizations and human performance technology practitioners' accountability and continuous improvement. 相似文献

From the early 19th century until the most recent two decades, open‐space and satellite museums featuring anatomy and pathology collections (collectively referred to as “medical museums”) had leading roles in medical education. However, many factors have caused these roles to diminish dramatically in recent years. Chief among these are the great advances in information technology and web‐based learning that are currently at play in every level of medical training. Some medical schools have abandoned their museums while others have gradually given away their museums' contents to devote former museum space to new classrooms, lecture halls, and laboratories. These trends have accelerated as medical school enrollment has increased and as increasing interest in biological and biomedical research activities have caused medical schools to convert museum space into research facilities. A few medical schools, however, have considered the contents of their museums as irreplaceable resources for modern medicine and medical education and the space these occupy as great environments for independent and self‐directed learning. Consequently, some medical schools have updated their medical museums and equipped them with new technologies. The Anatomical Museum of Leiden University Medical Center in The Netherlands and the Medical Museum of Kawasaki Medical School in Kurashiki, Okayama, Japan, are two examples of such upgraded museums. Student surveys at Leiden University have indicated that all students (100%) found audio‐guided museum tours to be useful for learning and majorities of them found guided tours to be clinically relevant (87%). However, 69% of students felt that museum visits should be optional rather than compulsory within the medical training curriculum.

The gross anatomy dissection course is a cost‐intensive piece of undergraduate medical education that students and professionals alike describe as very important within the overall medical curriculum. We sought to understand more explicitly students' valuation of gross anatomy as an “important” course and so developed a quantitative longitudinal questionnaire. Medical students (n = 124) enrolled in the winter term 2006/2007 gross anatomy course at the Ulm University Faculty of Medicine were surveyed anonymously prior to, in the middle of, and at the end of the dissection course. Subgroups of students expressing rising or falling opinions of course value were identified and correlated with student opinions about the course's ability to convey professional competencies. Five‐point Likert scales were used for each survey item, which included such standardized instruments as the NeoFFI, BSI, and FBM. The study confirmed that medical students believe dissection to be valuable. Students indicated that participation in the course facilitated acquisition of anatomy knowledge as well as skills related to teamwork, coping with stress, and, to a lesser extent, time management. Students also noted that they developed less empathy than expected beforehand. Significant subgroup differences were observed relative to the competencies of teamwork, stress coping strategies, and empathy, as well as in students' stress levels associated with having to take a dissection course. Our study builds on previous work that has shown dissection courses help students develop professional competencies. The increase in professionalism might be a reason for the generally high value students place on the gross anatomy dissection course, Anat Sci Educ 3:3–11, 2010. © 2010 American Association of Anatomists. 相似文献

In this article we will provide a general overview of the situation of the digital publishing in Europe starting from the
insights provided by the Editech conference, the international day of advanced study organized by the Italian Publishers Association
and focused on the trends, perspectives and applications of technological innovation in publishing at an international level.
It is the main Italian event dedicated to book publishing with the aim of helping publishers define their short- and medium-term
digital strategies, while being aware of the opportunities and risks involved in the conversion to digital of their business
model. The Editech 2010 main focus had been: the market and the national and international situation of digital publishing,
the new buying and reading behaviors of consumers, e-books and content for e-readers and mobile devices, new production processes
(XML, ePub, digital printing) and the distribution scenario and the diffusion of digital content. 相似文献

Introduction: Pharmacists need effective skills in accessing and using Internet‐based medicines information (IBMI) for themselves and their consumers. However, there is limited information regarding how pharmacists use the Internet. Objectives: To develop and use a research instrument to measure pharmacists’ Internet knowledge, search skills, evaluation of and opinions about using IBMI. Methods: A structured questionnaire examining general Internet knowledge, ability to search for and select pertinent IBMI, evaluation of IBMI, opinions about using IBMI and current Internet use was developed. Exploratory factor analysis was performed to analyse IBMI evaluation. Results: 208 pharmacists responded (response rate 20.6%). There was a large variation in pharmacists’ scores. Mean scores were low for General Internet Knowledge (mean 7.91 ± 3.62; scale 0–16), Search and Selection of IBMI (4.98 ± 2.91; 0–10) and Opinions on IBMI (44.51 ± 9.61; 0–80). Four factors [Professionalism of website (4 items; factor loading 0.62–0.87; Cronbach’s α 0.84), Disclosure (5; 0.37–0.79; 0.73), Appropriateness of content (5; 0.32–0.50; 0.65), Standard of information (6; 0.31–0.48; 0.58)] were extracted from the evaluation scale, explaining 36.89% of the total variance. Conclusions: A tool was developed to evaluate pharmacists’ skills and opinions in using IBMI. A wide range of skills and opinions highlighted the need for training in online information literacy. 相似文献

This study aimed to compare specific technical and tactical indicators of the team and centre forward role of Euro League, and Italian Serie A1, Serie A2, and Serie B men's water polo club competitions. A notational analysis was performed on 21 water polo matches to evaluate the occurrence of technical and tactical team and centre forward indicators, highlighting differences among championships according to chi-square analyses. Differences emerged for Counterattack (P < 0.001) and Power-Play (P < 0.001) possessions, Even (P < 0.001; Euro League: 3 ± 1, Serie A1: 3 ± 2, Serie A2: 3 ± 2, Serie B: 6 ± 4) and Power-Play (P = 0.001) goals, and exclusions and penalties (P = 0.008) of the team during Even possessions. Relatively to the role analyses, effects emerged for perimeter players playing events (P = 0.049), as well as for centre forwards' goals (P = 0.007) and exclusions and penalties (P < 0.001; Euro League: 8 ± 1, Serie A1: 6 ± 2, Serie A2: 6 ± 2, Serie B: 3 ± 2) occurring at the end of Even possessions. Therefore, in Euro League, and Italian Serie A1 and Serie A2, teams perform a high occurrence of Power-Play possessions following up an exclusion, especially achieved by the centre forward during Even possessions, while, in Italian Serie B, goals were mostly scored during Even possessions, with a relevant contribution from the centre forward role. 相似文献

This study investigated the impact of contingent variables on the relationship between four predictors and students' satisfaction with e‐learning. Five hundred and twenty‐two university students from 10 intact classes engaging in online instruction were asked to answer questionnaires about their learning styles, perceptions of the quality of the proposed predictors and satisfaction with e‐learning systems. The results of analysis of variance and structural equation modelling analyses showed that two contingent variables, gender and job status, significantly influenced the perceptions of predictors and students' satisfaction with the e‐learning system. This study also found a statistically significant moderating effect of two contingent variables, student job status and learning styles, on the relationship between predictors and e‐learning system satisfaction. The results suggest that a serious consideration of contingent variables is crucial for improving e‐learning system satisfaction. The implications of these results for the management of e‐learning systems are discussed. 相似文献
