Does local dynamic stability of kayak paddling technique affect the sports performance? A pilot study     

Daniel Hamacher  Tobias Krebs  Guido Meyer  Astrid Zech 《European Journal of Sport Science》2018,18(4):491-496

During competition, kayak athletes must optimally adapt to environmental factors (e.g. wind, waves) to achieve peak performance. However, the ability to adapt to such perturbations has never been assessed in kayak paddling. Therefore, the aim of the current study was to evaluate the local dynamic stability in sports technique of youth sprint kayak athletes. In a cross-sectional study, 14 healthy male athletes were recruited from an elite youth sprint kayak squad. During an incremental kayak ergometer test, mean power, heart rates and local dynamic technique stability of hands, arms, trunk and paddle were registered and the association with the athletes 2000?m free-water times were estimated using mixed models. The 2000?m free-water performance significantly predicted the paddles (p?=?.037) local dynamic stability whereas no association was found for the trunk or the upper extremity kinematics. In conclusion, kayak athletes with high-performance capability over 2000?m paddling depict high local dynamic technique stability. This emphasizes the importance of a stable technique for advanced kayak skills, especially regarding paddling movements.  相似文献   

Sozialer Status und Spendenverhalten Ehrenamtlicher in Sportvereinen

While much research has been done to analyze whether socioeconomic status influences prosocial behavior in the form of donations, no consensus has yet emerged in the relevant literature. We contribute to this research by studying, based on a dataset from a questionnaire of volunteers of sports clubs in Palatinate (part of Rhineland–Palatinate, Germany) whether social status affects donations. We measured social status of volunteers of sports clubs along the dimensions income, vocation, education and we considered status crystallization. Results showed that social status has a positive effect on the likelihood of donations. We report similarities and differences across different categories of donations (donations to one’s own sports club, to other clubs, to aid projects, and political parties).  相似文献   

Pädagogische Begleitung: Handlungsform und Systemmerkmal     

Dieter Nittel  Nikolaus Meyer 《Zeitschrift für Erziehungswissenschaft》2018,21(5):1063-1082

This contribution aims to lay down the theoretical potential of accompaniment as a phenomenon and developing this point further from a pedagogical perspective. The core assumption is that accompaniment represents both a pedagogically relevant phenomenon of action as well as an essential characteristic of the system. In this sense, accompaniment can be understood as creating a possibility for looking at phenomena of education on a micro and a macro level. Thus, the assumption follows that a central signature of the social system – namely that of inclusion – has already been incorporated by the pedagogically organized system of lifelong learning a long time ago. This finding has far-reaching consequences for levelling the hierarchy between different layers of the education and learning systems.  相似文献

Video Presentations that have to Teach     

T. Earl  Katharina Meyer‐Hartwig 《Learning, Media and Technology》1986,12(3):167-173

To be successful, an instructional video presentation needs to be effective, valued, liked and efficient, and educationalists and designers should strive (explicitly and implicitly) to satisfy these criteria. In the interests of optimum teaching effect, a didactical distinction is recommended between video presentations that have to ‘instruct’, ‘explain’, ‘tell’ and ‘let encounter’. A schema or frame of reference is proposed, the use of which (it is claimed) can help to optimise communication between video producer, teacher and instructional designer  相似文献   

史怀哲、敬畏生命与世界宗教     

马文·梅耶  邵明 《宜宾学院学报》2012,12(1):1-5

史怀哲“敬畏生命”的生态伦理学认为一切生命不仅有价值,而且是神圣的.他把这看成是逻辑和思想的必然结果.他强调人类与其他各种生命形式之间休戚与共的关系,他所遵循的“不伤害生命”或“善待其他生命”等基本原则,与世界上其他宗教和文化的根本信念是一致的,如基督教、印度教、佛教、儒家和道家等,尽管理论上稍有不同.史怀哲还以自己一生都在非洲热带丛林里进行医疗事业的传奇经历,亲自实践着他的这一生命伦理理念,全身心地、多方面地努力追求敬畏生命的道德生活.  相似文献

The role of teacher behavior in adolescents’ intrinsic reading motivation     

Jessie De Naeghel  Martin Valcke  Inge De Meyer  Nele Warlop  Johan van Braak  Hilde Van Keer 《Reading and writing》2014,27(9):1547-1565

Given the weak intrinsic reading motivation of many adolescents on the one hand and the importance of this type of motivation for reading competence on the other hand, the aim of the present study is to identify the related role of teacher behavior. To pursue this aim, a secondary analysis was carried out on PISA 2009 data. More particularly, data of a subsample of 4,269 Flemish 15-year olds were examined by means of multilevel modeling. In line with self-determination theory, the results provide evidence for the significance of perceived autonomy-supportive, structured, and involved teacher behavior. Teacher involvement was most strongly associated with adolescents’ intrinsic reading motivation. Further, students’ perception of teachers’ autonomy support was particularly related to girls’ intrinsic reading motivation.  相似文献   

“I never felt more uncomfortable in my life”: University students' discursive constructions of “the lesbian convention”     

Laura Shue O'hara  Marcy Meyer 《Communication Studies》2013,64(2):137-153

In this paper, we draw from the body of theories on the discursive construction of prejudice to examine the communicative strategies that university students employ to manage their talk about lesbian women who visited their campus during a women's music festival. We found that, although students used a number of strategies that communicate heterosexism subtly, the students relied more often on strategies that communicate heterosexism in blatant ways‐a finding that contradicts much of what has been written about the discursive construction of prejudice. We theorize that these findings are, in part, due to the methods we used to gather data: No researcher was present during the discussions. We conclude that this methodology may be useful for teaching students the powerful nature of discourse in the perpetuation of prejudice.  相似文献   

The Library as Service-Learning Partner: A Win–Win Collaboration with Students and Faculty     

Nadean J. Meyer  Ielleen R. Miller 《College & Undergraduate Libraries》2013,20(4):399-413

ABSTRACT

This case study of a quarter-long collaborative service-learning project, repeated over several quarters, involves technical communication students and librarians at Eastern Washington University. The librarians needed to promote RefWorks, while the technical communication faculty needed a client with a computer-based tool for students to learn and then teach to others. Working in teams, fifty-eight students planned and executed fifteen RefWorks workshops for students. The majority of students liked using RefWorks and gave successful presentations to their peers. This project increased awareness and usage of RefWorks while also affording librarians a student-centered perspective on teaching and using this tool. In this win–win collaboration, students learned useful skills in addition to developing a sense of community with the library.  相似文献
