Purpose:

The authors conducted a survey examining (1) the current state of evidence-based medicine (EBM) curricula in US and Canadian medical schools and corresponding learning objectives, (2) medical educators'' and librarians'' participation in EBM training, and (3) barriers to EBM training.

Methods:

A survey instrument with thirty-four closed and open-ended questions was sent to curricular deans at US and Canadian medical schools. The survey sought information on enrollment and class size; EBM learning objectives, curricular activities, and assessment approaches by year of training; EBM faculty; EBM tools; barriers to implementing EBM curricula and possible ways to overcome them; and innovative approaches to EBM education. Both qualitative and quantitative methods were used for data analysis. Measurable learning objectives were categorized using Bloom''s taxonomy.

Results:

One hundred fifteen medical schools (77.2%) responded. Over half (53%) of the 900 reported learning objectives were measurable. Knowledge application was the predominant category from Bloom''s categories. Most schools integrated EBM into other curricular activities; activities and formal assessment decreased significantly with advanced training. EBM faculty consisted primarily of clinicians, followed by basic scientists and librarians. Various EBM tools were used, with PubMed and the Cochrane database most frequently cited. Lack of time in curricula was rated the most significant barrier. National agreement on required EBM competencies was an extremely helpful factor. Few schools shared innovative approaches.

Conclusions:

Schools need help in overcoming barriers related to EBM curriculum development, implementation, and assessment.

Implications:

Findings can provide a starting point for discussion to develop a standardized competency framework.  相似文献

This article demonstrates that recent Romanian cinema manifests the features of a new, coherent, and strong film movement that was correctly tagged as a late new wave in the context of postcommunist significant changes that have shaped the Romanian society and its artistic milieu over the past two decades. By discussing the general characteristics of new waves and the legacies of the most influential cinematic movements of the 20th century, several common features are highlighted, as is the Romanian directors’ capacity to integrate and restate these influences through innovative techniques and an original approach to reality. The analysis is exemplified through the exploration of some of the most representative films of the recent Romanian cinema, prizewinners at prestigious international film festivals.  相似文献

Visualization and mapping techniques can build a dynamic picture of information practices, including action research, within libraries, raising awareness of how the information landscape at each library may both support and retard research into the library's information practices. These techniques have implications for researchers as they generate richer data than interview or survey techniques, or methods that only take one “snapshot” of the state of practice. The data are also available to participants immediately, thus, allow for co-operative inquiry to take place in the library. Examples are offered from a project under way in two Norwegian academic libraries.  相似文献

In August 2009, the Herbert Wertheim College of Medicine Medical Library opened its doors to students, faculty, and staff. One of the many challenges before opening the library was developing a unique and autonomous interlibrary loan service for its patrons. This article examines the decisions in choosing the best document delivery system, the management of funds, and the selection of holdings for a new medical library. Along with these decisions, there is discussion on the significance of costs, turnaround times, and challenges going forward.  相似文献

If one wanted to measure the historic level of multimedia industry concentration in Mexico, it would not be necessary to use statistics, financial analysis, viewer ratings, or other evaluation systems. The maximum level of concentration is 1, and, in Mexico, that number belonged for 20 years to Grupo Televisa (1973–1993). Televisa's position was lost in 1993 when entrepreneur Ricardo Salinas Pliego launched TV Azteca. This paper explores the principal strategies used by TV Azteca to overcome the entry barriers set by the Televisa monopoly. The paper also presents an economic valuation of this duopoly market 7 years after the shift in market structure.  相似文献

The chances are the first thing you when you set out to write an article is the title. But what factors transform a mediocre title into a good title? Firstly, it should be both informative and specific, using words or phrases likely to be used when searching for information, for example ‘nurse education’ rather than simply ‘nurse’. Secondly, it should be concise yet convey the main ideas clearly; articles with short titles reporting study findings have been found to attract higher numbers of viewing and citations. Thirdly, provide details of the study design to assist the reader in making an informed choice about the type of project your article is reporting. In taking these small steps when developing your title, your title can present a more concise, retrievable and clear articulation of your article.  相似文献

In this paper, the robust stability problem of structured linear systems is analyzed. In order to preserve the structure of the initial system, the structure of the admissible perturbations is characterized. Frobenius and infinity matrix norms are used to study the robust stability of the system affected by different admissible perturbations. Upper bounds for the perturbations are obtained, which guarantee that the perturbed system remains stable. Finally, some examples are shown to illustrate the results.  相似文献
