Performance Enhancement and Politicisation of High-Performance Sport: The West German ‘air clyster’ Affair of 1976     

Henk Erik Meier  Marcel Reinold 《国际体育史杂志》2013,30(12):1351-1373

While the politicisation of high-performance sport is perceived to represent one of the driving forces behind doping, we know not much how exactly the cold war in sports has affected sporting misconduct in western societies. Therefore, we propose here to distinguish between ideological and institutional politicisation and explicit and implicit acceptance of dubious practices. We apply our framework to analyse the West German ‘air clyster’ affair of 1976 in order to examine to what extent the politicisation of high-performance sport during the cold war affected the search for innovation in performance enhancement. We find that political pressure for improved competitiveness in West German sport had served to create a semi-autonomous high-performance sport sector in West Germany where blurred lines of accountability allowed questionable practices to prosper. While the public despised the use of questionable methods, sportive nationalism served to eclipse dubious practices. West German sport leaders adopted insofar a permissive attitude towards questionable practices as sporting misconduct was not sanctioned. Thus, our results strongly suggest that sport's politicisation during the cold war facilitated the search for performance-increasing methods in western societies.  相似文献   

Effects of Ventilation on Segmental Bioimpedance Spectroscopy Measures Using Generalizability Theory     

A. Allan Turner  Albert Lozano-Nieto  Marcel Bouffard 《Measurement in physical education and exercise science》2013,17(2):116-129

The purpose of this study was to examine the effect of three ventilation conditions (i.e., normal, regimented, and no-ventilation) on the reproducibility of bioimpedance scores in humans for the forearm and trunk segments. One hundred able-bodied North American men and women, from 18 to 71 years of age, volunteered as participants. The experimenters used a Xitron Bio-Impedance Analyzer System model 4200 instrument with Hydra software (Xitron Technologies, San Diego, California, USA) to collect bioimpedance data on extracellular fluid and intracellular fluid scores. The experimenters analyzed the data using the generalizability theory,with persons as the facet of differentiation and time as the facet of generalization. The major findings were (a) ventilation conditions did not have a significant impact on the reproducibility of the test scores, (b) the forearm segment produced consistently higher intracellular fluid generalizability coefficients across three ventilation conditions for both gender groups when compared to the trunk segment, (c) the trunk segment produced intracellular fluid generalizability coefficients that were higher for the male group, and (d) the measurement error affected extracellular fluid scores less than segmental intracellular fluid scores.  相似文献

Metacognitive skills and intellectual ability of young adolescents: a longitudinal study from a developmental perspective     

Manita van der Stel  Marcel V. J. Veenman 《European Journal of Psychology of Education - EJPE》2014,29(1):117-137

In the last decades, students increasingly have been placed in the role of active learners with responsibilities for their own learning. Students have to be able to plan their learning activities and execute them in a systematic and orderly way and to monitor and to evaluate their learning and to reflect on it. All aforementioned skills are components of metacognitive skillfulness. The first objective was to gain insight in the development of both quantity and quality of metacognitive skills in young adolescents (aged 12–15 years). The second objective was to establish whether development of metacognitive skills is intelligence related or relatively intelligence independent. Finally, the generality vs. domain specificity of developing metacognitive skills was investigated. In a 3-year longitudinal study, participants performed two different tasks (text studying and problem solving) in two different domains (history and math), while thinking aloud. Results show that between the age of 12 and 15 years, metacognitive skills do not develop linearly or at the same pace. Furthermore, metacognitive skills contribute to learning performance, partly independent of intellectual ability. Finally, the results show that metacognitive skills appear to be predominantly general by nature over the years. Although a smaller domain-specific component was found as well in the first 2 years, this component disintegrated in the third year. The age around 15 years appears to be a relevant point in time during the developmental trajectory of metacognitive skills: Growth is (temporarily) put on hold, while the nature of these skills becomes fully general.  相似文献

Innovative product and customer retention: Strategies in the music business ‐ An analysis of Santana's enhanced album “Shaman”;     

Michel Clement  Marcel Engh  Bodo Thielmann 《媒体管理杂志》2013,15(3):190-198

Abstract

The music business is facing hard times with declining CD sales and increasing piracy. Whereas the economic downturn is one reason for lower sales, the industry has decided to target the second factor, the fast diffusion of technologies such as CD burners and peer‐to‐peer networks like KaZaA allowing massive illegal distribution of music. Some labels focused on an offensive strategy to promote their artists. New services are being added to so called Enhanced CDs that create a new user experience. These CDs offer bonus content (i.e. videos, additional songs, pictures, or lyrics) stored directly on the CD that can be accessed on the PC. Other CDs offer (additionally) online access to actual bonus content or services (i.e. tour dates or news) if the CD is entered in the FC. The impact of these services on consumer experience has not yet been researched in depth and it remains unclear if consumers actually use the offered services on Enhanced CDs. The music label Arista has introduced several new albums on Enhanced CDs to the market providing more value to the user instead of reducing the utility by focusing only on copy protection. This article analyzes the usage of such services provided by Arista and focuses on Santana's new album “Shaman”;. Using a unique data set provided byfavakitty Media (Bandlirik) and Arista, we show for the first time what services are actually used by Santana fans and compare the results to albums of other artists such as TIC or Toni Braxton. Our results indicate that Enhanced CDs are used frequently by a relatively small group of fans, providing more value to the customer and creating a stronger relation between fans and artists.  相似文献   

Buttercups and daisies: building a community of practice amongst teachers in a Brazilian university     

Marcel do Nascimento Botelho  Steve Bartlett 《Educational Action Research》2013,21(2):183-196

This article examines the promotion and adoption of action research as an instrument of institutional change by academic staff in a Brazilian rural university. The results of the research are presented showing the mobilisation of a group of volunteers, the implementation of their action research projects and the sustainability of the process. Particular attention is drawn to the significance of an insider change agent/facilitator as the initiator of the action research process and how his role became superfluous as the networks evolved into true communities of practice. On reflection the original composite daisy model of Melrose and Reid has been discarded in favour of a simpler buttercup‐type flower model of analysis to describe the process.  相似文献

Un profil de compétences pour les professeurs d’informatique de l’enseignement secondaire camerounais     

Marcel Fouda Ndjodo  Virginie Blanche Ngah  Erick Patrick Zobo 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》2013,59(2):177-196

A competency profile for teachers of Computer Science in Cameroonian secondary education – In 1998, the Cameroonian government decided to introduce Computer Science as a school subject. To implement this decision, it began to train teachers of Computer Science according to the same training model used for teachers of other disciplines. Despite the consensus that seems to be emerging from the scientific community regarding the need to give priority to a cross-disciplinary use of information and communication technologies (ICT) in primary and secondary education, some countries, such as Cameroon, have opted to teach Computer Science. While such a political choice might in principle appear to be inappropriate for the development of students’ ICT skills, the article shows that it nevertheless introduces teachers into the system who have a predisposition to act as catalysts for the pedagogical integration of ICT. Such a development could occur provided these teachers are trained in a range of additional skills – those proposed in the article – which would enable them to contribute effectively. If this approach were implemented, sub-Saharan countries such as Cameroon would, in their Computer Science teachers, have access to human resources capable of quickly generalising the cross-disciplinary use of ICT in the education system.  相似文献   

The Crux of Crucial Experiments: Duhem's Problems and Inference to the Best Explanation     

Weber  Marcel 《The British journal for the philosophy of science》2009,60(1):19-49

Going back at least to Duhem, there is a tradition of thinkingthat crucial experiments are impossible in science. I analyseDuhem's arguments and show that they are based on the excessivelystrong assumption that only deductive reasoning is permissiblein experimental science. This opens the possibility that someprinciple of inductive inference could provide a sufficientreason for preferring one among a group of hypotheses on thebasis of an appropriately controlled experiment. To be sure,there are analogues to Duhem's problems that pertain to inductiveinference. Using a famous experiment from the history of molecularbiology as an example, I show that an experimentalist versionof inference to the best explanation (IBE) does a better jobin handling these problems than other accounts of scientificinference. Furthermore, I introduce a concept of experimentalmechanism and show that it can guide inferences from data withinan IBE-based framework for induction.
