基础教育场域中的跨文化教育与管理——上海市三所接受外籍学生随班就读学校的个案研究

伴随着上海国际化大都市发展进程,越来越多的外籍中小学生选择随班就读于上海市中小学校。文中通过对国家、上海市及各区县、相关学校制订的招收外籍中小学生的政策、规定,申请入读程序和就读方式的整理,选取其中三所学校做个案研究,希望对处于摸索阶段的基础教育场域中的跨文化教育与管理有所启示。     

关于建构中小学教师跨文化培训体系的几点设想——基于上海市中小学接收外籍学生随班就读的管理现状

伴随着上海市基础教育国际化的悄然走近,中小学教师跨文化培训呼之欲出。本文在总结国内外教师跨文化培训研究现状的基础上,结合上海市中小学外籍学生跨文化管理实地调研的相关结果,对开展中小学教师跨文化培训提出了＂跨文化教师培训需分层部署,多方协调,注重借鉴,辐射推广＂、＂紧紧围绕‘培养文化移情能力,形成多元文化平等共存的自觉意识’和‘增强跨文化敏感度,提高跨文化交际能力’这两大基础开展培训＂以及＂跨文化教师培训课程可采用必修、选修和校本研究的形式＂等设想。     

1980年以来河南省主要粮食作物产量对气候变化的敏感性分析

根据1980—2015年河南省及周边39个气象站点逐日观测数据,选取与主要粮食作物生育机理相关的气候指标,运用气候统计方法分析河南省主要粮食作物生育期内水热气候要素的时空变化。结合统计数据,运用面板非线性回归模型分析主要粮食作物产量对气候变化的敏感性。研究发现：①河南省冬小麦返青期最低气温和生育期平均气温均呈显著增加趋势,在空间上两者升温速率呈现从河南省中部向周边递减的特征。夏玉米生育期总日照时数呈明显减少趋势,其减少速度在豫中地区最快,在豫西南地区最慢。②从敏感效应来看,冬小麦和夏玉米产量分别对生育期平均气温和生育期总日照时数的敏感效应最强,对生育期总降水量的敏感效应均最弱。从敏感区看,冬小麦产量敏感区主要分布在豫北、豫西和豫南地区,夏玉米则集中在豫西和豫东地区。③冬小麦生育期平均气温突变后有利于除豫北以外共83.3%区域内产量的增加,返青期最低气温突变后有利于豫北和豫东共44.4%区域内产量的增加。夏玉米生育期总日照时数突变后对豫中和豫西共44.4%区域的产量增加有利。     

Intercultural language teaching as a catalyst for teacher inquiry

This study investigated how two teachers of languages, facilitated by university researchers, developed their practices with regard to intercultural language teaching. Taking a qualitative case study approach, we collected data from classroom observations, interviews, debriefing conversations, and guided reflective pieces written by the teachers. Findings indicate that the opportunities for teachers to inquire into their own practices shifted these teachers' approaches to language teaching to accommodate a curriculum expectation to develop students' intercultural communicative competence in plurilingual contexts. The study offers valuable insights for teacher education into the ways teachers' inquiries can support teachers’ responses to curricular change.     

网球拍弦磅数变化对优秀网球职业运动员底线击球效果的研究

为研究优秀的网球职业运动员是否对球拍拍弦磅数变化有更好的区分能力以及拍弦磅数变化是否会影响到击球效果,本研究使用网球发球机发球,让18名优秀的网球职业运动员参加一个用不同拍弦磅数球拍的(从47磅~64磅)击球测试。从实验结果来看,61%测试者不能准确的区分6磅的拍弦磅数变化,击球后球飞行的平均速度是117 km/h,击球平均速度与落点失误数都与球拍拍弦磅数不存在显著性差异。研究结果表明,优秀网球职业运动员对网球拍弦磅数变化的分辨能力与敏感度较低;优秀的网球职业运动员击球的落点与球拍磅数不存在显著性相关;在底线击球中优秀的网球职业运动员对使用不同磅数的球拍有着很强的适应能力与控制能力。

运用文献资料法、运动力学和数学分析等方法,建立了铅球投掷距离与铅球的出手速度、出手角度和出手高度三个因素之间关系的数学模型。利用MATLAB编程计算,通过作图逐层对影响铅球投掷成绩的因素进行了灵敏度分析和定量分析,分析了三个影响因素的主次关系,尤其是明确了一直以来备受争议的出手角度和出手高度的影响,为科学的训练、选材以及成绩的提高提供理论依据。     

Insulin sensitivity derived from oral glucose tolerance testing in athletes: Disagreement between available indices

The aims of the present study were to determine whether available “fasting” and oral glucose tolerance test-derived insulin sensitivity indices could effectively discriminate between individuals with higher than normal insulin sensitivity, and whether they would all provide similar information in clinical practice. Sprint runners (n = 8), endurance runners (n = 8) and sedentary controls (n = 7) received a 75-g oral glucose tolerance test. All participants were healthy lean males, aged 21?–?29 years. Besides glucose and insulin responses, a total of nine such indices were computed. Fasting as well as post-load glucose concentrations were similar in the three groups, while basal plasma insulin and the insulinaemic response to glucose were both higher in untrained individuals (at P?<?0.05 and P?<?0.02, respectively). There were no differences between endurance and sprint runners. The results for insulin sensitivity, however, were quite variable: three indices showed that both groups of athletes were more insulin-sensitive than controls; three indicated that this was the case for endurance runners only; one indicated that this was the case for sprint runners only; and two showed that sprint runners were more insulin-sensitive than either sedentary individuals or endurance runners (all differences were significant at P?<?0.05). Controlling for total body weight or lean mass did not effectively resolve this disagreement. Apparently, the various insulin sensitivity indices examined provided different quantitative and qualitative information, despite insulin action being greater in both groups of athletes relative to controls, as reflected by their similar glucose tolerance with lower insulin concentrations. We suggest, therefore, that the use and interpretation of such indices among physically active individuals be made with caution.     

WASMOD模型参数敏感性与相关性分析

对水文模型参数进行敏感性和相关性分析,可以减少率定参数的数量、提高模型运行效率,并可以为优化和改进模型结构提供依据.本文采用局部分析法和相关系数法讨论了WASMOD模型中的五个参数对目标函数的敏感程度以及参数之间的相关程度.研究发现,在黑河流域上游山区的径流模拟过程中,WASMOD模型中影响降水形态的温度参数a1对目标函数最为敏感;其次是影响地表径流的参数a6和影响融雪过程的温度参数a2;基流参数a5最不敏感.模型参数之间的相关性不是很强,这也说明,模型结构已得到很好的优化;为保证模型的模拟效果,模型参数的数量不能减少.
