优秀背越式跳高运动员技术的快速特征   总被引：4，自引：0，他引：4  

吴敏  陈亚中 《首都体育学院学报》2005,17(1):74-75,78

本文运用文献资料法和逻辑分析法从助跑、起跳、过杆三个技术环节深入分析优秀背越式跳高运动员技术的“三快”特点。得出以下结论：助跑阶段起跳脚着地瞬间较高的质心水平速度和最后两步良好的助跑节奏是取得成功的必要条件。起跳快表现为起跳脚蹬伸速度快，摆臂摆腿快且节奏明显。过杆快体现在头肩开始过杆时展体快，头肩过杆后挺髋快、臀部过杆后收腹举腿快。  相似文献

Formale objektorientierte Softwareentwicklung mit FOX{\cal F}{{\scriptstyle{\cal O}{\cal X}}}     

Klaus Achatz und Wolfram Schulte 《Informatik - Forschung und Entwicklung》1997,12(4):174-185

Zusammenfassung.   Wir stellen die neue Methode vor, die auf die formale Entwicklung sequentieller, objektorientierter Softwaresysteme abzielt. ist eine synergetische Kombination aus der semiformalen Methode Fusion und der formalen Spezifikationssprache Object-Z. Die Methode unterscheidet ausdrücklich Analyse und Entwurf, um die Komplexit?t und die unterschiedlichen Aufgaben der Softwareentwicklung zu bew?ltigen. In jeder Entwicklungsphase werden Zustands- und Verhaltensspezifikationen in graphischer oder textueller Form erstellt. Wir geben Beweisverpflichtungen an, um zu gew?hrleisten, da? die entwickelten Spezifikationen formal konsistent und vollst?ndig sind, und da? das resultierende System zur Ausgangsspezifikation konform ist. Wir illustrieren die Anwendung von an einem einfachen Beispiel, einem Grapheditor. Eingegangen am 24. Dezember 1996 / Angenommen am 8.10.1997  相似文献

The multi-paradigmatic character of contemporary educational action research: a promising perspective or an underlying threat?     

Eleni Katsarou 《Educational Action Research》2017,25(5):673-686

From the very first moment action research started to be used in the social research field until now, it has presented significant variations. Action research looks like a mosaic of theoretical and methodological approaches, named differently from time to time and/or from place to place: for example, practitioner inquiry, practitioner research, teacher research, participatory action research, and so forth. The basic aims of this article are to find the reasons for this and to discuss the implications of the phenomenon. Starting with the first issue, we could ask ourselves: why do we today find so many and considerable variations in action research approaches in the literature? The evident reason is because action research draws upon many theoretical paradigms that – in some circumstances – are not only different, but also contradict each other. Hammersley states characteristically that action research draws upon positivism, pragmatism, hermeneutics, critical theory and postmodernism! After such claims, we can easily wonder: how can such a multi-paradigmatic approach compose cohesive methodological proposals? We can also pose another crucial question: although we can easily understand that this multi-paradigmatic nature is a real advantage which gives action research a pluralistic essence, is it really ‘a strong indicator of the power of action research to reinvent itself according to local needs’ as Somekh stated, or might it at the same time conceal serious risks?  相似文献   

College/University Counseling Centers Supporting Study Away: Challenges and Opportunities     

Charles C. Morse  Janet Dee Spoltore  Paul Galvinhill 《Journal of College Student Psychotherapy》2017,31(4):325-335

Research points to significant numbers of students on college campuses experiencing mental health distress and an ever increasing number of college students who are choosing to make an off-campus educational experience a part of their college careers. When we consider both of these trends together, it is quite apparent that a significant number of students with mental health concerns will spend periods of time studying away from campus, with converging concerns among college mental health and study away professionals about how to best support these students. This article seeks to outline both challenges and opportunities inherent in the collaboration between campus professionals in supporting students with mental health issues before and during their study away experiences.  相似文献
