优秀举重运动员降体重后体重控制与运动能力恢复的个案研究

目的:通过对优秀举重运动员大幅度降低体重导致运动能力大幅度下降后的能力恢复训练的个案进行研究,探索大幅度降低体重对运动员机体的影响和能力恢复期运动员机体各项指标的变化规律.方法:长期跟踪测试优秀举重运动员降体重后的体重控制与运动能力恢复期间的身体成分、血象(红细胞计数、血球压积、血红蛋白等)、肌酸激酶、血尿素、血清睾酮、皮质醇等指标的变化及营养情况调查.结果:运动员体重在降体重后控制良好,运动能力逐步恢复,血清睾酮持续低下.结论:大幅度持续降体重将导致运动能力和血清睾酮大幅度下降,在较长一段时间内难以恢复;随着能力恢复训练的进程,运动员的竞技能力逐渐上升,但并未完全恢复;降体重造成的HB等氧运系统指标下降能在较短时间内通过营养和训练手段的调节得以恢复.     

What Can the Teacher Learn in the Classroom?

Our research is concerned with teacher’s knowledge, and especially with teacher’s processes of learning, in the classroom, from observing and interacting with students’ work. In the first part of the paper, we outline the theoretical framework of our study and distinguish it from some other perspectives. We argue for the importance of distinguishing a kind of teacher’s knowledge, which we call didactic knowledge. In this paper, we concentrate on a subcategory of this knowledge, namely observational didactic knowledge, which grows from teacher’s observation and reflection upon students’ mathematical activity in the classroom. In modeling the processes of evolution of this particular knowledge in teachers, we are inspired, among others, by some general aspects of the theory of didactic situations. In the second part of the paper, the model is applied in two case studies of teachers conducting ordinary lessons. In conclusion, we will discuss what seems to be taken into account by teachers as they observe students’ activity, and how in-service teacher training can play a role in modifying their knowledge about students’ ways of dealing with mathematical problems.     

论司法考试语境下的法学案例教学

实行司法资格准入制以来,司法资格证书是就业＂敲门砖＂。目前的法学案例教学所占比例较小,以＂解决案例＂为目的,缺乏对案例的学理反思,与司法考试的要求相去甚远。应加强案例教学,拓展推理式、比较式、抗辩式、模拟式等多元化案例教学途径。     

Bullying and the Unique Socioemotional Needs of Gifted and Talented Early Adolescents: Veteran Teacher Perspectives and Practices

Much is written at the elementary school level concerning bullying and the socioemotional needs of gifted and talented (GT) students; however, in the last 10 years, little qualitative research exists concerning the early adolescent GT age group. In the social environment of classroom life, early and current research indicates that many of these students experience neurotic perfectionism, overexciteabilities (OEs), developmental asynchrony, and bullying. The formation of autonomous classes (GT-only classes) has afforded some hope concerning the amelioration of such problems; nevertheless, in this study, detailed evidence of classroom bullying in the form of social ostracism and teasing has been found with this GT age group. If left unchecked, psychological autopsies have shown these students suffering emotional difficulties and even committing suicide as a result of school and classroom torment. With such potential for classroom bullying problems, few studies address what veteran teachers of early adolescent GT students do to keep students psychologically safe. Within the social milieu of classroom life, and in comparison to research standards, this study explores three efficacious teacher perspectives and practices.

格理论与例外格结构推导

管约论认为ECM受NP格的驱动推导而成，赋格主要允准条件为管辖和邻近，其结果往往因限制过于严格而无法达到完全解释。简约论认为DP的格特征是固有的，DP的移动是为了满足对功能词的形态特征核查的需要。结合BowerB(2002)将v的功能分成Pr和Tr的假设，我们认为在简约论的框架内对ECM的推导进行解释更为合理：DP必须前移到[Spec，Tr]，[Spec，T]位置，对Tr、T的格特征进行核查。     

Case study research: training interdisciplinary engineers with context-dependent knowledge

It is now widely acknowledged that water management discipline is transforming, from being a public health and flood prevention challenge of the nineteenth century to a multi-dimensional challenge of water security for the twenty-first century. In order to train water engineers to be capable of working with this holistic multi-dimensional approach, a new paradigm in engineering education is required. Adjustments already made to undergraduate coursework are not enough; this new paradigm requires modifications to the PhD in engineering, with greater emphasis on interdisciplinary case study research. Such a change can deliver PhD graduates with both sufficient social and technical knowledge, who can then go on to become the hybrid lecturers crucially needed for training future water engineers.

Learning through working: a case study of Chinese college students in South Korea

This qualitative case study was designed to provide an understanding of the work experience of Chinese college students in South Korea. A growing number of Chinese students are coming to South Korea for college education, and their aspirations for better work materialize into work experiences in South Korean businesses. In-depth interviews were conducted with five Chinese students to investigate their learning experience at local workplaces. The Chinese students' work experience not only led them to a deeper understanding of local culture and language, but also gave them integral learning within an experiential, situated learning environment.
