The distance-time relationship over a century of running Olympic performances: A limit on the critical speed concept     

Dekerle J  Nesi X  Carter H 《Journal of sports sciences》2006,24(11):1213-1221

We analyse the evolution of the slope (critical speed) and the y-intercept (anaerobic distance capacity) of the linear distance-time relationship over a century of Olympic running performances. The distance-time relationship of each Olympic Games (1920-2004) was plotted using the performances in the 800-, 1500- and 5000-m track events. Values for critical speed and anaerobic distance capacity were determined by linear modelling. Mean performances for the 800, 1500 and 5000 m were 104.9 +/- 1.5 s (1.4%), 217.2 +/- 2.8 s (1.3%) and 808.9 +/- 18.4 s (2.3%), respectively. Critical speed improved during the first three-quarters of the twentieth century to reach a plateau in 1984. This is in accordance with the literature (Peronnet & Thibault, 1989) and suggests that "human aerobic endurance" has improved within the century (+13.4%) and tends to stabilize. Anaerobic distance capacity was highly variable over the century (coefficient of variation = 9.4%) and did not show a linear improvement over the years as has previously been suggested (Peronnet & Thibault, 1989). This could be due to an artefact in the application of the two-parameter model to only three Olympic performances. A limitation to the use of this linear mathematical model to fit physiological data may have been demonstrated.  相似文献

The production of available potash from the natural silicites     

Allerton S. Cushman  George W. Coggeshall 《Journal of The Franklin Institute》1912,174(6):663-678

In this paper a summary is given of the various processes which have been proposed for making the potash in the natural silicates available as a fertilizer.Experimental trials of a new rotary kiln process for treating feldspar are described, which depends upon a previous treatment before furnacing, consisting of a method of aggregating or clumping the mix so that chemical contact of the reacting substances is brought about during the subsequent processing. The qualitative and quantitative results obtained on a number of experimental trials on a mill scale of operation are presented and discussed. It is shown that it is possible to economically manufacture a potash fertilizer containing free lime from feldspar, and for a sufficiently low cost to make an industry based upon the method worthy of consideration.  相似文献

A survey of Web-based business models for e-government in the Netherlands     

Marijn Janssen  George Kuk  René W. Wagenaar 《Government Information Quarterly》2008

Governments worldwide are increasingly using Web-based business models to enhance their service delivery. Yet the concept of the business model is unexplored within the context of e-government. Drawing upon the literature on e-commerce, we develop a taxonomy for analyzing Web-based business models for e-government. Based on a systematic survey of 59 e-government Web sites in the Netherlands, our findings indicate that most of the Web sites use the content provider or direct-to-customer business models, while only a few are using novel business models. Overall, the concept of business model is appealing and useful in the public sector. Specifically it compliments research on Web site quality by analyzing and describing Web sites using atomic e-government business models and suggesting improvements by using combinations of business models.  相似文献   

Consortial Ebook Archiving Environmental Scan     

George Machovec 《图书馆管理杂志》2018,58(1):81-90

Academic libraries and consortia are spending the vast majority of their material budgets on digital content, including ebooks. A review of ebook preservation activities for the North American library consortia is provided along with a look at the major preservation services such as Portico, CLOCKSS and HathiTrust. Publishers and ebook aggregators are also examined to provide a broad environmental scan of the current ebook preservation activities and risks.  相似文献

‘Experimental’ secondary modern education in Britain, 1948–1958     

Laura Carter 《Cultural and Social History》2016,13(1):23-41

Studies of mid-twentieth century education in England and Wales have conventionally hinged on the 1944 Education Act, foregrounding policy over practice. This article considers the significance of the inter-war progressive educational movement for postwar educational developments. It presents a case study of one teacher who was active in the early ‘experimental’ years of secondary modern education, suggesting that this period was important in the making of ‘modern’ education. It seeks to complicate both negative and positive readings of ‘meritocracy’ in postwar educational history. This article also highlights the paucity of available source material for the study of the secondary modern school, arguing that attention should be paid to well-documented cases, placed in context.  相似文献
