医保新方案     
贺端斯:嗯,首先,我认为这次新方案糟透了。我是说,55美元的挂号费?这太荒谬了。我可不想每次看病都要付55美金。更不要说500美元的自付额了,这样一来,每次看病都要花去半张千元大钞!天啊!  相似文献

Three experiments examine 18- to 24-month-old (N = 78) toddlers' ability to spatially orient objects by their major axes for insertion into a slot. This is a simplified version of the posting task that is commonly used to measure dorsal stream functioning. The experiments identify marked developmental changes in children's ability to preorient objects for insertion, with 18-month-olds failing completely and 24-month-olds succeeding easily. In marked contrast, 18-month-olds preorient their empty hands for insertion into the same slots. This developmental dissociation between aligning hands and aligning objects to slots suggests that the key developmental change is in action with the goal of object-to-object alignment versus action on an object.  相似文献

选取CISR的IT治理框架,对中国企业的IT治理状况进行调查,引用《中国计算机用户》的调查问卷,提出关于CISR的三个假设。进行描述性统计和相关性分析,展示了中国IT治理的基本状况,通过实证来验证假设,得出:一流绩效的企业都有着精心设计的治理机制;IT治理绩效呈钟形的正态分布;注重利润率的一流绩效企业常采用集权的IT治理模式;注重增长率的一流绩效企业常采用分权的IT治理模式;注重资产利用率的一流绩效企业常采用集权与分权混合的IT治理模型,据此推断各行业的IT治理实践经验。  相似文献

有专家认为,教练员的指导不应被简单地定义为一些教学方法或他们所传授某种专门体育知识,而应被看作一种更为复杂的活动。“它本质上是一种社会实践活动,是教练员、运动员及俱乐部环境之间的互动产生的活动”,因此,教练员的指导是一种“复杂的社会关系”,是发生在“教学背景”下的一种关系。所谓的教学背景就是一个整体,即这个背景中的所有参与者及个人行为都是一个整体过程。正是每一部分之间的互相依赖才使“教学背景”成为一个单独的实体。  相似文献

The aim of this study was to examine the effects of match location, quality of opposition, and match status on the technical aspects of performance within a single professional British football team. Forty matches from the 2002--2003 and 2003--2004 domestic league seasons were notated post-event using a computerized notational analysis system with 13 on-the-ball behaviours and corresponding outcomes (successful or unsuccessful) assessed. Log-linear modelling procedures indicated that the incidences of all on-the-ball technical behaviours, with the exception of "set-pieces", were influenced by at least one of the three situation variables, with both independent and interactive effects found. In contrast, logit modelling suggested that there was no general influence of the situation variables on the outcomes of the on-the-ball behaviours. The findings emphasize the need for notational analysts and coaches to consider the potential independent and interactive effects of match location, quality of opposition, and match status when assessing the technical components of football performance, particularly those relating to behaviour occurrence. Future research should consider the effects of additional situation variables purported to influence the mental, physical, technical, and tactical components of football performance.  相似文献

Squash is a popular racket sport that requires intermittent activity with frequent bursts of near maximal-intensity exercise. Consequently, effective physiological and thermoregulatory responses are important contributors to performance during squash match-play. Controlled field-based simulation protocols have been introduced in a growing number of sports, which allow sports scientists to investigate changes in physiology and the efficacy of various interventions in sport-specific contexts. This study aimed to develop an exercise protocol that simulates the physiological requirements of elite squash match-play. Eight elite junior squash players (age 16.2+/-0.8 years, height 1.76+/-0.06 m, body mass 61.3+/-5.9 kg; mean+/-s) completed the following in a randomized order: (1) a squash match against a player of similar standard and (2) a squash-specific incremental exercise protocol (multistage squash test [MST]) followed by the squash simulation protocol (SSP). The multistage squash test was continued for 18.0+/-1.0 min and elicited near maximal post-MST heart rates, blood lactate concentrations and ratings of perceived exertion (198+/-9 beats.min-1, 5.7+/-1.7 mmol.l-1 and 18+/-1, respectively). The SSP was 12.2 min in length compared with mean game length during competitive matches of 10.0+/-1.6 min (P=0.27). Peak heart rates were similar during the SSP and match-play (192+/-11 and 189+/-6 beats.min-1, respectively; P=0.44). Mean exercising heart rates were similar during the SSP (180+/-8 beats.min-1) and match-play (179+/-13 beats.min-1; P=0.73). Peak blood lactate concentrations during the SSP and match-play were 3.5+/-1.5 and 2.4+/-1.2 mmol.l-1 (P=0.07), respectively. Peak ratings of perceived exertion during the SSP and match-play were similar (17+/-2 and 17+/-2, respectively; P=0.64). It was concluded that the SSP closely replicated the demands of squash match-play in elite junior squash players. Furthermore, the SSP provides coaches and scientific support staff with a controlled squash-specific exercise protocol that has potential application in the objective investigation of a range of interventions such as training programmes, nutritional supplements and strategies to maintain core body temperature.  相似文献

世界各国的种族、民族、文化、语言和宗教的多样性随着新移民的到来不断丰富.这也给公民身份和公民教育这两个概念带来了新的挑战.此研究指出民族国家(nation-states)建构既能适应新人口群体又能保证国家统一之新理念的必要性.文化多元的民族国家需要在统一性和多样性中寻找平衡点.同时,文章还介绍了民族、文化、语言和宗教多样性给公民身份带来的挑战,并强调应该通过改革公民教育使学生不仅能同时具有明显的文化、国家、地区和全球身份,还能获得参与到公民生活申所需的知识与技能.  相似文献
