Efficient processing of ordered XML twig pattern matching based on extended Dewey

Finding all occurrences of a twig pattern is a core operation of extensible markup language （XML） query processing. Holistic twig join algorithms, which avoid a large number of intermediate results, represent the state-of-the-art algorithms. However, ordered XML twig join is mentioned rarely in the literature and previous algorithms developed in attempts to solve the problem of ordered twig pattern （OTP） matching have poor performance. In this paper, we first propose a novel children linked stacks encoding scheme to represent compactly the partial ordered twig join results. Based on this encoding scheme and extended Dewey, we design a novel holistic OTP matching algorithm, called OTJFast, which needs only to access the labels of the leaf query nodes. Furthermore, we propose a new algorithm, named OTJFaster, incorporating three effective optimization rules to avoid unnecessary computations. This works well on available indices （such as B~-tree）, skipping useless elements. Thus, not only is disk access reduced greatly, but also many unnecessary computations are avoided. Finally, our extensive experiments over both real and synthetic datasets indicate that our algorithms are superior to previous approaches.     

社会心理层面精神文明建设的几个问题

作为一种社会现象，社会心理反映社会生活的直观性浅表性、作用于社会生活的直接性、影响社会生活的广泛性的特点，决定了它是两个文明之间相互作用、辩证运动的中介。随着我国现代社会经济制度从计划体制向市场体制的转型和现代科技的迅速发展及其在社会生产生活中的广泛作用，现代中国人的社会心理出现了两大变化趋向，即转型期社会心理问题和科技社会心理问题。这给社会主义精神文明建设提出了新课题、新任务。社会主义精神文明建设应当在弘扬积极健康的社会心理，克服治疗消极的社会心理，建设良好的社会心理环境等方面多做工作，做好工作，促进两个文明的协调发展和社会的全面进步。、     

Perceptions of anatomy: critical components in the clinical setting

The evolution in undergraduate medical school curricula has significantly impacted anatomy education. This study investigated the perceived role of clinical anatomy and evaluated perceptions of medical students' ability to apply anatomical knowledge in the clinic. The aim of this study was to develop a framework to enhance anatomical educational initiatives. Unlike previous work, multiple stakeholders (clinicians, medical students, and academic anatomists) in anatomy education were evaluated. Participants completed an eleven-point Likert scale survey written by the investigators. Responses from both clinical educators and medical students at Penn State Milton S. Hershey Medical Center and College of Medicine suggest that medical students are perceived as ill-prepared to transfer anatomy to the clinic. Although some areas of patient management differ in relevancy to anatomical education, there are areas of clinical care which were uniformly ranked as relying heavily on anatomical knowledge (imaging and diagnostic studies, physical examination, and arrival at correct diagnosis) by a variety of clinical specialists. Our results suggest a need for advanced anatomy courses to be taught coincidental with medical students' clinical education. Development of these courses would optimally rely on input from both clinicians and academic anatomists, as both cohorts rated clinical anatomy similarly (P ≥ 0.05). Additionally, we hypothesize that preclinical students' application of anatomy would be enhanced if clinical context was derived from areas of clinical care which rely heavily on anatomy, whereas courses designed for advanced medical students will benefit from anatomical context focused on specialty specific aspects of clinical care identified in this study.     

高职院校开设英语晨读课之探析

随着国际交往的日益频繁,英语作为国际交流语言的作用也日渐重要,英语口语也越来越受到重视。因此,口语教学已成为英语教学的重点。开设晨读课有利于创造英语氛围,有助于提升学习兴趣,是高职学生提高口语水平的有效途径之一。探讨如何通过选取晨读的内容、形式,如何加强晨读监管和考核等来改进晨读实施方法,促进晨读效果。     

试论高校思想政治教育进大学生公寓

新的世纪,我国的高等教育事业正处于加速发展的重要时期,随着高校结构调整和办学规模的扩大,以及高校后勤服务社会化步伐加快和学分制改革的推行,学生公寓越来越成为大学生学习、生活的重要场所.相应地,思想政治教育的基本组织形式和主要工作渠道也应该有所改变.因此,学生思想政治工作进公寓,成为高等教育改革与发展的时代要求,更是新时期加强高校学生思想政治教育工作实效的必由之路.
