Physiological responses to 1000-m ergometer time-trial performance in outrigger canoeing

Graded exercise tests are commonly used to assess peak physiological capacities of athletes. However, unlike time trials, these tests do not provide performance information. The aim of this study was to examine the peak physiological responses of female outrigger canoeists to a 1000-m ergometer time trial and compare the time-trial performance to two graded exercise tests performed at increments of 7.5 W each minute and 15 W each two minutes respectively. 17 trained female outrigger canoeists completed the time trial on an outrigger canoe ergometer with heart rate (HR), stroke rate, power output, and oxygen consumption (VO2) determined every 15 s. The mean (+/- s) time-trial time was 359 +/- 33 s, with a mean power output of 65 +/- 16 W and mean stroke rate of 56 +/- 4 strokes min(-1). Mean values for peak VO2, peak heart rate, and mean heart rate were 3.17 +/- 0.67 litres min(-1), 177 +/- 11 beats min(-1), and 164 +/- 12 beats min(-1) respectively. Compared with the graded exercise tests, the time-trial elicited similar values for peak heart rate, peak power output, peak blood lactate concentration, and peak VO2. As a time trial is sport-specific and can simultaneously quantify sprint performance and peak physiological responses in outrigger canoeing, it is suggested that a time trial be used by coaches for crew selection as it doubles as a reliable performance measure and a protocol for monitoring peak aerobic capacity of female outrigger canoeists.  相似文献

Democratic and Anti-Democratic Regulators of the Internet: A Framework     

Michael L. Best  Keegan W. Wade 《The Information Society》2007,23(5):405-411

We employ Lessig's framework of regulation to conceptualize the relationship between the Internet and democracy. Lessig defines four classes of regulators, forces that control and define systems such as the Internet. They are markets, architectures, norms, and laws. We propose that a “democratic regulator” is a force that serves to enhance civil or political liberties. And we argue by example that there are democratic (and, indeed, anti-democratic) regulators that control aspects of cyberspace. Expressing the democratic effects of the Internet in this manner may prove useful for future comparisons across existing Internet and democracy theories, especially in the realm of quantitative analyses.  相似文献   

Interpretative Responses to English Educational Television     

B. Wade  R. A. Poole 《Learning, Media and Technology》1985,11(3):171-176

The paper is concerned with the need to stimulate and evaluate pupils’ responses to educational television broadcasts in English. In particular, it presents a comparative assessment of written follow‐up work during a series of broadcasts. Case study methods are used within one comprehensive school and involve 49 15‐year‐old pupils. Results suggest that those pupils consistently engaging in small‐group discussion are likely to produce better written work and to develop greater independence in formulating their ideas.  相似文献

Teacher evaluation in Illinois: school leaders’ perceptions and practices     

Alyson Leah Lavigne  Roger Wade Chamberlain 《Educational Assessment, Evaluation and Accountability》2017,29(2):179-209

The aim of the current study is to assess school leaders’ perceptions and practices in the context of a new policy that emphasizes teacher evaluation. The study draws from survey data of 606 K-12 school leaders in the USA in a state implementing a new teacher evaluation model under Race to the Top. Findings illustrate that school leaders spent significant time on teacher evaluation. Some felt this was a good investment of time (e.g., rich conversations with teachers), increasing the ability for evaluations to improve instruction. Most, however, perceived the time demands as a cost (e.g., spending longer hours on the job, delegating more tasks to others). School leaders felt very confident in their ability to conduct observations and provide feedback to teachers. The opposite was found for student achievement data. Administrators’ reported preparedness, confidence, and beliefs suggest that barriers exist to using student achievement data to evaluate teachers. Findings suggest that school leaders need resources to build capacity, particularly in accommodating the new time demands of teacher evaluation. Administrators could benefit from professional development that addresses the use and value of student achievement if this measure continues to be a substantial component in teacher evaluation models.  相似文献

Beyond the Repository: A Mixed Method Approach to Providing Access to Collections Online     

Brian Wade Garrison 《New Review of Academic Librarianship》2013,19(3):291-299

After providing access to over 100 video interviews conducted by a professor with notable entertainers and personalities from film through an institutional repository, an experiment was conducted to discover whether a larger audience could be gained by adding a subset of 32 of these videos to YouTube. The results, over 400,000 views, indicate that libraries should cultivate a mixed method approach to providing access to digital content.  相似文献
