ABSTRACT

This study aimed to compare mechanical variables derived from torque-cadence and power-cadence profiles established from different cycle ergometer modes (isoinertial and isokinetic) and modelling procedures (second- and third-order polynomials), whilst employing a novel method to validate the theoretical maximal power output (P_max). Nineteen well-trained cyclists (n = 12 males) completed two experimental sessions comprising six, 6-s maximal isoinertial or isokinetic cycling sprints. Maximal pedal strokes were extracted to construct power–cadence relationships using second- and third-order polynomials. A 6-s sprint at the optimal cadence (F_opt) or optimal resistance (T_opt) was performed to assess construct validity of P_max. No differences were found in the mechanical parameters when derived from isokinetic (P_max = 1311 ± 415, F_opt = 118 ± 12) or isoinertial modes (P_max = 1320 ± 421, F_opt = 116 ± 19). However, R² improved (P < 0.02) when derived from isoinertial sprints. Third-order polynomial modelling improved goodness of fit values (Standard Error, adjusted R²), but derived similar mechanical parameters. Finally, peak power output during the optimised sprint did not significantly differ from the theoretical P_max in both cycling modes, thus providing construct validity. The most accurate P-C profile can be derived from isoinertial cycling sprints, modelled using third-order polynomial equations.  相似文献   

Motivation to read in grades K – 2: a cross-cultural perspective

ABSTRACT

We examined early elementary children’s reading motivation in four different countries. Results revealed that reading motivation is a stable construct in countries like Chile, Finland, Greece, and the United States. Motivation to read followed similar patterns across the countries, with increased scores at the end of the school year. This trend differs from what has been reported in the literature for older students. Significant gender differences were observed mainly for Finnish and Greek students. Understanding early reading motivation from a cross-cultural perspective can help identify commonalities in the initial development of reading motivation, and deepen our understanding about how it may differ in different cultural contexts.  相似文献

On reliability and robustness of scientometrics indicators based on stochastic models. An evidence-based opinion paper     

Wolfgang Glänzel 《Journal of Informetrics》2010,4(3):313-319

In the present paper we give an overview over the opportunities of probabilistic models in scientometrics. Four examples from different topics are used to shed light on some important aspects of reliability and robustness of indicators based on stochastic models. Limitations and future tasks are discussed as well.  相似文献   

Changing from a special school to an inclusion service     

Carol Bannister  Vivienne Sharland  Vivian Upton  David Walker  & Gary Thomas 《British Journal of Special Education》1998,25(2):65-69

Members of the Somerset Inclusion Project and Gary Thomas (professor and reader in education at the University of the West of England, Bristol) discuss the need for schools to become more inclusive in response to the Government's recent Green Paper (DfEE, 1997), which emphasises that special schools need to work in different ways and to provide services to local mainstream schools. The notion that inclusion is right and segregation is wrong led the staff to convert the Princess Margaret School (PMS) in Taunton, Somerset to an inclusion service.  相似文献

Redefining library space: managing the co-existence of books, computers, and readers     

Mary Augusta Thomas   《The Journal of Academic Librarianship》2000,26(6)

Library design must better integrate space for collections and computers than it has. This article presents planning strategies that integrate digital products and print collections based on patron needs. Many flexible solutions in developing buildings will enhance library service in the technologically dynamic future.  相似文献

Senior Design Project Course: A Case Study     

Thomas F. Hain  Stephen M. Jodis 《Computer Science Education》2013,23(2):169-187

The two‐quarter Senior Design Project course given in the Computer Science and Engineering Department of Auburn University gives undergraduate students a significant computer system development experience by working on a project from proposal to prototype. Heavy emphasis is placed on team‐ and project‐management principles, team presentations, the application of standard structured development methodologies, and the generation of formal deliverables after each project phase. Project ideas are canvassed from faculty, graduate students, local industry and community, and from the students themselves. We believe that the knowledge and experience acquired by students from working in a team on a substantial project gives them an insight and perspective that is unattainable through the standard lecture paradigm. The course has received enthusiastic endorsement from industry, accrediting boards, and participating students (albeit at the end of the course!).  相似文献
