Effects of problem-based learning as reported in curricular comparison studies have been shown to be inconsistent over different medical schools. Therefore, we decided to summarize effects of a single well-established problem-based curriculum rather than to add up sometimes-conflicting findings from different problem-based curricula. Effect sizes were computed for 270 comparisons. The results suggest that students and graduates from the particular curriculum perform much better in the area of interpersonal skills, and with regard to practical medical skills. In addition, they consistently rate the quality of the curriculum as higher. Moreover, fewer students drop out, and those surviving need less time to graduate. Differences with respect to medical knowledge and diagnostic reasoning were on average positive but small. These outcomes are at variance with expectations voiced in recent contributions to the literature. They demonstrate that constructivist curricula can have positive effects on learning even if they deemphasize direct instruction. 相似文献

Because of a proposed policy, public school teachers in Hawaii are facing the possibility of being randomly tested for illegal drugs. Random drug testing has many implications and its impact is questionable. In this article, the author scrutinizes the controversial drug-testing policy for both troubling and promising aspects and how educators may perceive it. Is this a safety issue or an invasion of privacy issue? 相似文献

摘要：习近平总书记高度重视体育事业，并围绕建设体育强国，加快“健康中国”建设发表了系列重要讲话。习近平关于体育系列重要讲话系统地阐述了对体育的认识与观点，是习近平体育观的集中体现。文章根据习近平系列重要讲话、有关体育指示的文献资料,应用原典分析法和对照式研究方法，系统分析和探析了习近平的体育观，深刻学习和全面领会了习近平新时代中国特色社会主义思想。首先，习近平体育观，涵盖严谨的科学体系。习近平明确指出，“人民身体健康是全面建成小康社会的重要内涵”，这既是“体育定位的新论”，又是习近平体育观的逻辑起点。“两大发展思想”，是习近平体育观的根本指导方针。“两大战略目标”，是习近平体育观的战略目标体系。“六大战略任务”，是习近平体育观的发展战略任务。“深化体育三大改革”是习近平体育观的发展动力机制。“坚持党的领导”是习近平体育观的制度保证；其次，习近平体育观具有坚持体育的问题导向、坚持体育发展的人民性、时代性、社会引领示范性、坚持体育创新驱动性的创新特征，这彰显了习近平体育观的伟大时代价值；最后，习近平体育观是新时代的创新性理论，是建设体育强国，努力实现建设“健康中国”目标的指导思想。 相似文献

Objective:
This paper examines the development and evaluation of an automatic summarization system in the domain of molecular genetics. The system is a potential component of an advanced biomedical information management application called Semantic MEDLINE and could assist librarians in developing secondary databases of genetic information extracted from the primary literature.Methods:
An existing summarization system was modified for identifying biomedical text relevant to the genetic etiology of disease. The summarization system was evaluated on the task of identifying data describing genes associated with bladder cancer in MEDLINE citations. A gold standard was produced using records from Genetics Home Reference and Online Mendelian Inheritance in Man. Genes in text found by the system were compared to the gold standard. Recall, precision, and F-measure were calculated.Results:
The system achieved recall of 46%, and precision of 88% (F-measure = 0.61) by taking Gene References into Function (GeneRIFs) into account.Conclusion:
The new summarization schema for genetic etiology has potential as a component in Semantic MEDLINE to support the work of data curators.Highlights
- Semantic MEDLINE streamlines information retrieval by succinctly expressing the meaning of sometimes complicated text and summarizing output according to a user''s needs.
- Semantic MEDLINE identifies genes noted in biomedical text as associated with a disease process.
- Semantic MEDLINE can potentially simplify secondary database curation.
Implications
- Library information retrieval services can potentially benefit from automated applications such as Semantic MEDLINE.
- Use of such automated applications can facilitate the library''s work in interdepartmental collaborative endeavors, thus reinforcing the library''s core value in its parent institution.

Structuration theory helps to explain the role of human agency in the reciprocal relationship between social systems and structures, which Giddens called the “duality of structure.” The theory explicates how power struggles emerge and are negotiated and, depending on the restructuration, can help to resolve conflict or lead to deteriorations and dysfunction. Research has reported that at least 60% of corporations are privately held and backed by venture capital. The relationships among investors, the corporate board members, and operating officers are strategic relationships that can build or destroy a venture. I used structuration theory to frame a case study of a power struggle over control of a private firm that evolved among investors and board members. This article describes the structuration processes that contributed to functional and dysfunctional outcomes, with implications for performance improvement specialists and human resource development practice and research. 相似文献

课程文化的实质,是课程文化最根本、最深层、最终极的规定性。以往的研究侧重从课程的角度或文化的角度来理解课程文化的内涵,应该说这是理解课程文化内涵的一种视角。本文从课程与文化两个概念的共同属性来把握课程文化的内涵。它是主体发展的文化资源。 相似文献

当今世界主要市场经济国家准备金率及其调整频率一般很低,部分国家甚至完全取消准备金工具使用,而我国不仅准备金率较高而且调整频繁,是重要的货币政策工具。准备金制度地位和作用巨大反差的原因在于,其调控目标和发挥作用的金融环境的不同。短期来看,准备金率依然是我国央行倚重的货币政策工具,但长期来看,弱化其使用是必然趋势,而弱化的主要条件是外部经济失衡问题明显好转、金融体系流动性过剩局面得到明显缓解、利率市场化机制基本形成。 相似文献
