W. W. Duffield Letter, MSS.1652
No full textAbstract: A letter from W. W. Duffield, former Union soldier, to Lewis Maney, former Confederate officer, Woodside, Pennsylvania, May 7, 1866.Scope and Content Note: This collection consists of one letter from Duffield to Major Lewis M. Maney, C.S.A., relative to a grape vine sent by Duffield to Maney in 1862, and to Maney's impending visit to Woodside. It also refers to Maney as one "who sheltered me when a stranger, and who healed and comforted me when wounded and a prisoner," evidently a reference to the two men's encounter during the Civil War. That, however, is the lone reference to the conflict.Biographical/Historical Note: William Ward Duffield was a former Union soldier and prisoner of war, writing after the war from Woodside, Pennsylvania, May 7, 1866
George Negus on Media and Culture: Interview by Lee Duffield
No full textThe interview was commissioned by M/C Dialogue online journal as one in a series with "cultural scholars". George Negus as a veteran reporter, presenter and commentator in Australian television current affairs, was questioned about responses of the journalistic profession to changes dveeloping in media at the start of this Century. He adopts a position that practitioners must adjust to the "opportunities" of new media, convergence or globalisation. In response to proliferation of media producers and outlets, he advocates a continuing role for professional journalists as centrally placed sense-makers. He says: "I hink what the information age will do is make analytical and opinion journalism even more important than it always has been, because the information being available to you, you’ll probably still require assistance in sifting it, assessing it, evaluating it … I think the great paradox will be that as information journalism becomes less important, because the information will be so freely available to any one of these gatekeepers, self styled journalists, the opinion journalism, and commentary and analysis will become more important – because most people don’t have time to do that; they’re too busy doing other things.

Comparison of the .VO2 response to 800-m, 1 500-m and 3 000-m track running events
No full textThe present study examined the V.O2 response to middle-distance track running events of 800 m, 1 500 m and 3 000 m and investigated the relationship between the speed of the V.O2 response ((1) and subsequent race performance
The validity of a repeated sprint ability test
No full textMany team sports require participants to repeatedly produce maximal or near maximal sprints of short duration (1-7s) with brief recovery periods, over an extended period of time (60-90 min). Therefore, an important fitness component for these sports is what is often termed repeated sprint ability (RSA). A variety of tests have been devised to assess RSA. However, while the reliability of some of these tests has been reported, there has been no published attempt to assess the validity of RSA tests. The purpose of the present paper was to assess the validity of a popular RSA test--the 5 x 6 s cycle test. Ten moderately-trained males (Mean+/-SD age: 23.6+/-3.0 yrs, mass: 71.8+/-7.4 kg, peak VO2: 46.32+/-4.16 ml.kg(-1)min(-1)) participated in the investigation. Following familiarisation, subjects reported to the laboratory at the same time of day, on three occasions, each separated by at least 48 hours. Testing consisted of a 5 x 6 s cycle test (5 x 6 s maximal sprints every 30 s), a graded exercise test (GXT) and a simulated game (3 x 15 min periods separated by five min). The simulated game consisted of a 1-min circuit that was repeated 15 times in each period. The circuit replicated typical movement patterns observed during motion analysis of field hockey games. Each circuit commenced with a 15-m maximum sprint through timing gates. Time to run 5, 10 and 15 m was recorded. Oxygen consumption was measured during both the GXT and the simulated game with a portable gas analysis system (Cosmed K4 b2, Italy). Correlation coefficients between dependent variables were calculated using Pearson's Product Moment (r). There was a significant correlation between power decrement during the 5 x 6 s cycle test and decrement in 15-m time across the three periods (r = 0.76, P<0.05), but not decrement in 10-m time (r = 0.54) or 5-m time (r = 0.42). These results suggest that the 5 x 6 s cycle test is valid for assessing the decrement in 15-m time, but not the decrement in 5 or 10m time. Thus, one measure of RSA (sprint decrement) appears to be specific to the test protocol, rather than a general quality. The most likely explanation is that the energy requirements of the 5 x 6 s cycle test more closely match those required to repeatedly run 15 m (mean time = 2.74 s) than to repeatedly run 10 m (mean time = 1.97 s) or 5 m (mean time = 1.13 s). It is therefore suggested that, while the 5 x 6 s cycle test is often used to assess RSA ability in a wide range of sports, it may need to be modified to reflect the common sprint distances found in specific sports
