One of the central narratives of the 1908 Olympic Games is the intense Anglo-American acrimony which culminated in the nadir of their sporting relations. One of the major controversies involved the 400 metres final which featured Halswelle, a British athlete, and three Americans – Carpenter, Robbins and Taylor. The final was declared void after Carpenter obstructed Halswelle and was disqualified. In protest the Americans withdrew Robbins and Taylor from the re-run and Halswelle won the gold medal unopposed. This paper explores the 400 metres final from the perspective of the British athlete Wyndham Halswelle utilising his diaries, photo albums, scrapbooks and the papers of his elder brother, Gordon. Serendipitously, the continual digitisation of newspapers also gave further insight into allegations of illegal team tactics by Carpenter and Robbins in the initial race. The article then further exploits these resources to develop a case study of Halswelle as an elite early-twentieth-century British amateur athlete. Differences in ideas of the amateur athlete ideal are often identified as an underpinning cause of international squabbling at the IV Olympiad and may have led to Halswelle’s decision to retire after the games at the age of 26 while still improving his performances. 相似文献

We present a user-centred, task-oriented, comparative evaluation of two within-document retrieval tools. ProfileSkim computes a relevance profile for a document with respect to a query, and presents the profile as an interactive bar graph. FindSkim provides similar functionality to the web browser “Find” command. A novel simulated work task was devised, where participants are asked to identify (index) relevant pages of an electronic book, given topics from the existing book index. The original book index provides the ground truth, against which the indexing results of the participants can be compared. We confirmed a major hypothesis, namely ProfileSkim proved significantly more efficient than Find-Skim, as measured by time for task. The study indicates that ProfileSkim was as least as effective as FindSkim in identifying relevant pages, as measured by traditional information retrieval measures, and there is some evidence that ProfileSkim is a precision-enhancing tool. Based on qualitative data from questionnaires, we also provide strong evidence to support our conjecture that the participants would be more satisfied when using ProfileSkim than FindSkim. The experimental study confirmed the potential of relevance profiling for improving within-document retrieval. Relevance profiling should prove highly beneficial for users trying to identify relevant information within long documents. 相似文献

Dynamic behaviour of soils used for natural turf sports surfaces 总被引:1,自引:0,他引:1
The modulus and damping properties of soils in compression are a function of soil type, water content, stress history and
loading rate. To model human–surface interaction with natural turf sports surfaces, stiffness and damping properties must
be determined at dynamic loading rates. Two contrasting soil types, a Sand and a Clay Loam, commonly used in sports surfaces
were loaded uniaxially to 2 kN at loading rates between 0.6 and 6 kN s−1 in modified dynamic soil testing apparatus. Soils were compacted prior to loading but initial cycles resulted in viscoplastic
deformation, with strain accumulation with repeated cycles of loading. Ultimately a resilient, viscoelastic steady-state equilibrium
with loading was established. Resilient modulus and damping ratio varied with soil type, water content, stress history and
increased significantly with loading rate. The resilient modulus of the Sand soil, typical of modern free-draining sand construction
natural turf sports surfaces, was significantly greater than that of a Clay Loam soil more characteristic of traditional natural
turf surfaces; reducing water content caused an increase in modulus and a decrease in damping ratio in the Clay Loam soil.
Determination of these properties provides initial data for the modelling natural turf surface behaviour in terms of both
ball and human interactions, with further research required to determine the effect of both grass roots and leaves on mechanical
behaviour. 相似文献

In the light of predictions of future protein shortages the non-agricultural routes to protein production have become an industrial reality. These routes are based on the continuous fermentation of micro-organisms to produce single cell proteins. Seen as only a long-term possibility a few years ago, many commercial enterprises now have successful SCP production facilities, while research and development in this field continues at a rapid pace. 相似文献

A case study of a lengthy and potentially disruptive experimental research project is used to examine ways in which the interests of researchers and schools may be reconciled. Attention is drawn particularly to the importance of joint recognition of the legitimacy of both sets of objectives. The pivotal role of a research assistant/teacher in facilitating sensitive and flexible responses to problems confronting both the research project and the school is discussed. Unexpected social benefits to the school arising from our implementation of the research assistant/teacher role are described. 相似文献

As part of the impetus to increase and widen participation in the UK, and in Scotland in particular, there has been considerable
effort put into creating links between Further Education Colleges (FECs) and Higher Education Institutions (HEIs). However,
because no unique identifier is used to track students between the two sectors, little is known in quantitative terms of the
nature of this progression. In this article using substantial datasets, and an approach known as Probability Matching, we
are able to provide novel data on the proportions of Scottish domiciled former FEC students within Scottish HEIs, and are
able to compare the characteristics of this subset of all students with the whole cohort within HE in a given year, 1999–2000. 相似文献
