谈如何实现档案工作的规范化标准化

在档案管理的实际工作中,档案工作规范化、标准化是实现管理现代化的重要环节,在搞好硬件建设的同时,做好文书处理工作则是实现档案工作规范化、标准化的重要基础工作.虽然文书处理工作与档案工作各有不同的工作任务,具有相对的独立性,但由于文书是档案的来源,档案是文书的归宿,所以,两者又是文档工作流程中紧密相关的工作环节.因此,我们必须强化系统思维意识,树立文书处理工作规范化、标准化与档案工作规范化、标准化同行的工作指导思想.……

体态语言在体育教学中的作用

正同学们都一致认为:体育课是最好上的课,大家可以任意运动,任意玩耍,老师也不管,放松放松多得劲。有的学习好的学生为了多学习,多做题,干脆就不去上。所以,体育课倒不如说是差学生的玩耍课,好学生的自习课。在中招体育加试上,同学们的滑稽动作和可怜的成绩,惹人发笑。为了扭转这一现象,我们学校上学期调来了一位新的体育老师,新体育老师的到来,改变了同学们对体育课的错误想法和认识。体育老师的得体谈吐举止,优美标准的体操动作,上课与同学们的亲和力等等,像磁石一样吸引着每一位学生,使他们对体育课着了迷、中了魔。我作为一名体育老师,不得不     

Medical neglect of a child: challenges for pediatricians in developing countries

OBJECTIVE: To conceptualize the underlying causes of the medical neglect of children in a developing country and to provide suggestions for the management of neglect by pediatricians. METHODS: A case history of a 4-year-old boy from Turkey with neglect of the required treatment for acute lymphoblastic leukemia is used to examine the causes and management of medical neglect. Results: Although epidemiological studies on child neglect are lacking, this case exemplifies how in DEVELOPING countries, reasons for neglect or non-compliance with medical recommendations and the roles and actions taken by the health care and the social service systems may differ from western populations. Common to both western and developing countries, the characteristics of the child, family, and society may be reasons for medical neglect. However, cultural fatalistic beliefs profoundly present in the developing world may also contribute to the medical neglect of a child. Identification of the neglect, a comprehensive, multidisciplinary assessment emphasizing the strengths within the family and the society, and the determination of the pediatric team to act in the best interest of the child may result in resolution of the neglect even in circumstances where resources within systems are not sufficient. CONCLUSIONS: In developing countries, increased emphasis on child neglect, its prompt recognition and management within the pediatric profession as well as at a health care and social service system levels are needed to address this prevalent and potentially fatal child health problem.     

Nutritional composition of Pakistani wheat varieties

Pakistani wheat varieties are grown over a wide agro-climatic range and as such are anticipated to exhibit yield and quality differences. It is therefore necessary to investigate the nutritional status of wheat varieties in terms of biochemical and physiochemical characteristics available for food and nutritional purposes in Pakistan. The result shows that wheat grains of different varieties contain a net protein level of 9.15%～10.27%, 2.15%～2.55% total fats, 1.72%～1.85% dietary fibers,77.65×10^-6～84.25×10^-6 of potassium and 7.70× 10 6～35.90× 10^-6 of sodium ions concentration, 0.24× 10^-6～0.84× 10^-6 of phosphorus, 1.44%～2.10% ash, 31.108～43.602 g of thousand grain mass （TGM） and 8.38%～9.67% moisture contents. This study is significant in providing an opportunity to explore the available wheat varieties and to further improve their nutritional excellence and also essential for setting nutritional regulations for domestic and export purposes.     

中职学校学生心理健康教育的探索研究

由于普高扩招,生源大战,职校学生的生源普遍欠佳,与普高生相比,无论是学习动机、学习兴趣、学习习惯、意志品质上都有一定的差距,而产生这些因素的本质其实在于他们没有良好的心理健康平台。因此、就职校学生的心理健康问题进行调查分析研究,并从寻找到相应的矫正对策成为当前广大职业教育工作者面临的一项迫切任务。     

Effort on homework in grades 5-9: development, motivational antecedents, and the association with effort on classwork

In 2 studies, an expectancy-value framework was applied to investigate effort expended on mathematics homework. In Study 1 (2,712 students in grades 5, 7, and 9; mean age=13.37 years), lower homework effort was found in higher grades. The effects of intrinsic value on homework effort were higher in the older cohorts, whereas the effects of the expectancy component were lower. In Study 2 (571 students in grades 8 and 9; mean age=14.72), an expanded expectancy-value framework was found to explain both homework and classwork variables. The means for effort and value were lower for homework than for classwork; these differences were partly moderated by students' conscientiousness. The implications of homework behavior and motivation for developmental research are highlighted.     

SVM for density estimation and application to medical image segmentation

A method of medical image segmentation based on support vector machine （SVM） for density estimation is presented. We used this estimator to construct a prior model of the image intensity and curvature profile of the structure from training images. When segmenting a novel image similar to the training images, the technique of narrow level set method is used. The higher dimensional surface evolution metric is defined by the prior model instead of by energy minimization function. This method offers several advantages. First, SVM for density estimation is consistent and its solution is sparse. Second, compared to the traditional level set methods, this method incorporates shape information on the object to be segmented into the segmentation process. Segmentation results are demonstrated on synthetic images, MR images and ultrasonic images.     

Proximity-to-goal as a constraint on patterns of behaviour in attacker-defender dyads in team games

The aim of this study was to determine whether spatiotemporal interactions between footballers and the ball in 1 vs. 1 sub-phases are influenced by their proximity to the goal area. Twelve participants (age 15.3 ± 0.5 years) performed as attackers and defenders in 1 vs. 1 dyads across three field positions: (a) attacking the goal, (b) in midfield, and (c) advancing away from the goal area. In each position, the dribbler was required to move beyond an immediate defender with the ball towards the opposition goal. Interactions of attacker-defender dyads were filmed with player and ball displacement trajectories digitized using manual tracking software. One-way repeated measures analysis of variance was used to examine differences in mean defender-to-ball distance after this value had stabilized. Maximum attacker-to-ball distance was also compared as a function of proximity-to-goal. Significant differences were observed for defender-to-ball distance between locations (a) and (c) at the moment when the defender-to-ball distance had stabilized (a: 1.69 ± 0.64 m; c: 1.15 ± 0.59 m; P < 0.05). Findings indicate that proximity-to-goal influenced the performance of players, particularly when attacking or advancing away from goal areas, providing implications for training design in football. In this study, the task constraints of football revealed subtly different player interactions than observed in previous studies of dyadic systems in basketball and rugby union.
