为什么运动会诱发哮喘?
哮喘是儿童期最常见的慢性呼吸系统疾病,我国儿童哮喘的患病率呈逐年上升趋势,这是一种对患儿和他的家庭都有很大影响的疾病.
确实,运动和呼吸道病毒感染、变应原暴露、情绪等诱因一样,是常见的哮喘诱发因素,多达90％的哮喘患儿存在一定程度的运动诱发的支气管收缩. 相似文献

The current study examined the relationship between oral reading fluency (ORF) and reading comprehension for students in second grade. A total of 84 participants were randomly assigned to one of four conditions that involved reading a grade‐appropriate passage with either 0%, 10%, 20%, or 30% scrambled words and answering subsequent comprehension questions. The correlation coefficient between ORF and the number of comprehension questions correctly answered was r = .54. Receiver operating characteristics were then used to empirically derive a minimum ORF score necessary for comprehension, indicating that when these students read 63 words correct per minute they successfully comprehended what they read. Finally, the diagnostic accuracy of the derived criterion of 63 words read correctly per minute was tested and resulted in overall correct classification of .80. © 2010 Wiley Periodicals, Inc. 相似文献

Potential growth of two widely-grown hybrid rice varieties in the Jinhua district of Zhejiang Province, Shanyou63 for mid-rice and Xieyou46 for late rice, was simulated using a crop growth model of WOFOST. Parameters of the rice growth in WOFOST were calibrated through field experiments from 1999 to 2002 in Jinhua. The potential yield simulated with WOFOST was about 12 t/ha for Shanyou63 and 10 t/ha for Xieyou46, which are in good agreement with the highest recorded yield obtained in this area. Under farmers practice, current yield is about 7.5 t/ha for Shanyou63 and 6.5 t/ha for Xieyou46. There is a gap between the actual rice yield and the potential yield for these two hybrid rice varieties grown in this area. The attainable target yields were set to 70% to 75% of their potential yields for the two varieties. A recently developed software ＂Nutrient Decision Support System （NuDSS）＂ for irrigated rice was used to optimize nutrient management for these two rice varieties. According to NuDSS, the optimal fertilizer N requirement for the target yields was about 150 kg/ha for Shanyou63 and about 120 kg/ha for Xieyou46, which were only about 70% of the fertilizer N application under current farmers＇ practice. Comparing with farmers＇ practice, there is great potential to increase actual rice yields and to reduce fertilizer N use rates by improving rice crop management practice in Jinhua. 相似文献

Abstract The status of the environmental education component of preservice teacher education programs is unknown nationally. This study surveyed 715 institutions of teacher education using a mail questionnaire. The response rate was approximately 63%. The results indicate that most schools have few requirements related to environmental education, and in the majority of schools environmental education is not institutionalized. 相似文献

Based on 30 syllabi and 108 questionnaire responsesfrom randomly selected U.S. colleges and universities,college geometry courses were analyzed with respect tocontent, pedagogy, and assessment. About 40% of thecourses start with elementary axioms and emphasizeEuclidean geometry or a mix of Euclidean andnon-Euclidean geometry; 23% employ a survey approach;and 20% employ an analytic or projective geometryapproach. In about 63% of the courses, the instructorlectures most or all of the time; in 36% of thecourses a substantial amount of class time is devotedto group work; and about 27% of the courses reflectnearly all the characteristics of good mathematicsteaching as defined by the NCTM Professional TeachingStandards. In most courses, in-class examinations,homework, and a final examination are the primaryevaluation tools; in about half of the courses atleast one alternative assessment contributes to thefinal grade. Common characteristics are evident butwide diversity exists also. A typical geometry coursedid not emerge from the data. 相似文献

Abstract The compliance of an integrated approach, principal component analysis （PCA）, coupled with Tagu chi＇s robust theory for simultaneous optimization of cor related multiple responses of wire electrical discharge machining （WEDM） process for machining SiCp rein forced ZC63 metal matrix composites （MMCs） is investi gated in this work. The WEDM is proven better for its efficiency to machine MMCs among others, while the particulate size and volume percentage of SiCp with the composite are the utmost important factors. These improve the mechanical properties enormously, however reduce the machining performance. Hence the WEDM experiments are conducted by varying the particulate size, volume fraction, pulseon time, pulseoff time and wire tension. In the view of quality cut, the most important performance indicators of WEDM as surface roughness （Ra）, metal removal rate （MRR）, wire wear ratio （WWR）, kerf （Kw） and white layer thickness （WLT） are measured as respon ses. PCA is used as multiresponse optimization technique to derive the composite principal component （CPC） which acts as the overall quality index in the process. Consequently, Taguchi＇s S/N ratio analysis is applied to optimize the CPC. The derived optimal process responses are confirmed by the experimental validation tests results. The analysis of vari ance is conducted to find the effects of choosing process variables on the overall quality of the machined component.The practical possibility of the derived optimal process conditions is also presented using SEM. 相似文献

Conclusion The study in this article provided insights into the emotional needs of managers during the Preacquisition Stage of a potential acquisition. One manager claimed that mergers are the wave of the future. If one of six managers believes this in the retail industry, then we might assume that one out of every six employees has thought this at some time in his/her working life or at least thought about how mergers in general affect his/her working life. Therefore, it seems vital that retail employees have the attitude that Acquisitions, of course, produce stress, but they are not always bad experiences that end up hurting the employees. With the opposite attitude, the Preacquisition Stage will most likely be fraught with low employee morale, increased stress, resistance to change, higher turnover, and lower productivity.The managers in the current study shared their reactions to the announcement of a potential merger. As can be expected, much stress and uneasiness was occurring. The suggested interventions in this article will help the EAP counselor respond to the stress through crisis, preventive, and educational methods. The employee assistance counselor can no longer wait for the merger to occur; rather, he/she must be involved early in the merger process, during the Preacquisition Stage. If employee assistance counselors do not begin insisting on early involvement, business mergers may remain on a contractual level only. The contractual level allows Hunsaker and Coombs (1988) to conclude that the psychological needs of the merging work forces are not typically considered, and people issues are mishandled as the acquirer improvises instead of following a strategically designed, systematically conducted program for corporate integration (p. 57). A systematically conducted program may help managers and employees feel more secure about their own careers; thus, about mergers in general. 相似文献

Abstract Two sets of software developed for early reading instruction (top rated and best selling) were reviewed and evaluated for gender portrayal of central and secondary characters of the opposite sex. Male central characters were present in 37% of the top-rated computer software and in 63% of the best selling software. Female central characters were observed in 16% of the top-rated software and 11% of the best selling software. The lack of consistency between children's software requires further investigation. In a more positive vein, when central characters and secondary characters of the opposite sex were compared for salient characteristics that could be classified as sex role stereotyping, no differences were observed. 相似文献
