冠心病人康复训练后有氧工作能力和心肌供氧的变化

目的：探讨康复训练后冠心病人进行定量负荷运动时有氧工作能力和心肌供氧的变化，以此为康复效果的评估提供依据。方法：25名男性冠心病人参加了12周有氧多样化运动康复训练，训练前、后对他们在递增负荷运动中的生理和临床指标进行了测定。结果：1）反映冠脉血流和心肌耗氧量的指标RPP，康复训练前在跑台的V级负荷时已超过200，康复训练后增加幅度则有显著下降（P〈0．01）；2）康复训练前受试者的血乳酸浓度（BL）在Ⅳ级运动负荷之后出现了突增（达到4．6mmol／L），而康复训练后他们运动中的BL增加平缓，始终保持较低水平；3）康复训练前在V级运动负荷时受试者的ST下降达到-0．9mm水平，这已接近心肌缺血的阈值，训练后心肌供血出现了明显的改善。结论：康复训练前冠心病人运动中反映运动系统缺氧的BL突增领先于心肌缺血阈值的到达；与康复训练前相比，康复训练后冠心病人在进行相同负荷运动时显示出有氧工作能力有所增强，心肌供氧状况有所改善。

Are preservice teachers prepared to teach struggling readers?

Reading disabilities such as dyslexia, a specific learning disability that affects an individual’s ability to process written language, are estimated to affect 15–20% of the general population. Consequently, elementary school teachers encounter students who struggle with inaccurate or slow reading, poor spelling, poor writing, and other language processing difficulties. However, recent evidence may suggest that teacher preparation programs are not providing preservice teachers with information about basic language constructs and other components related to scientifically based reading instruction. As a consequence preservice teachers have not exhibited explicit knowledge of such concepts in previous studies. Few studies have sought to assess preservice teachers’ knowledge about dyslexia in conjunction with knowledge of basic language concepts. The purpose of the present study was to examine elementary school preservice teachers’ knowledge of basic language constructs and their perceptions and knowledge about dyslexia. Findings from the present study suggest that preservice teachers, on average, are able to display implicit skills related to certain basic language constructs (i.e., syllable counting), but fail to demonstrate explicit knowledge of others (i.e., phonics principles). Also, preservice teachers seem to hold the common misconception that dyslexia is a visual perception deficit rather than a problem with phonological processing. Implications for future research as well as teacher preparation are discussed.     

歌唱呼吸与情感的联系

自16世纪美声唱法诞生以来，诸多声乐教育家认为：歌唱的动力是呼吸。“谁懂得了呼吸，谁就掌握了歌唱。”由此可见，呼吸在声乐演唱中的重要性。而歌唱发声的技巧是为歌唱的内容服务的，歌唱蕴藏着丰富的情感要素。但如何借助作品本身的情感因素合理地运用具体恰当的呼吸演唱好作品，充分体现作品的情感，使听众产生情感上的共鸣是声乐教学与演唱的目的之一。

贵州省旅游引导水库移民安置模式的研究

水库移民安置是水库顺利建设的基础,也是贵州省的重要民生问题.从安置区移民的长远发展分析,目前“大分散,小集中”的有土安置模式存在着局限性,新的安置思路迫切需要探索和实践.而旅游引导安置的模式有鼓励和吸引投资,促进社区重建;促使移民脱离有土安置的依赖,推动当地建设开发;有利于库区社会稳定与文化发展、重构等诸多优势,应该成为贵州省水库移民安置探索的重要内容.     

"Sea Turtles" and "Ground Beetles" [Land Turtles] Should Shake Hands

In accordance with Chairman Mao's brilliant directive, "Choose students from among workers and peasants who have practical experience," and under the direction and with the assistance of the University Student Recruitment Work Group of Kansu Province, we selected in September last year 211 workers and peasants and sent them to study at Lanchow University, Kansu Normal University, and other institutions of higher learning. These institutions have generally reported that the quality of the students chosen is quite good.     

Peter Effect in the Preparation of Reading Teachers

The Peter Effect (Applegate & Applegate, 2004 Applegate, A. J. and Applegate, M. D. 2004. The Peter Effect: Reading habits and attitudes of teacher candidates. The Reading Teacher, 57: 554–563. [Web of Science ®] , [Google Scholar]) claimed that one cannot be expected to give what one does not possess. We applied this notion to reading teacher preparation and hypothesized that teacher educators who do not possess an understanding of basic language constructs would not prepare teacher candidates with an understanding of these constructs considered essential for early reading success. Results from a survey of basic language constructs revealed similar patterns in performance between teacher educators and their respective teacher candidates, which served as initial validation of the Peter Effect in reading teacher preparation.
