Structure of expert players' activity during competitive interaction in table tennis

This study analyzed the activity of expert table tennis players during a match, in reference to course of action theory (Theureau, 1992). Matches were videotaped, and the players' verbalizations as they viewed the tapes were collected a posteriori. The data was analyzed by (a) transcribing the players' actions and verbalizations, (b) decomposing their activity into elementary units of meaning, and (c) grouping the elementary units into larger sets. The results showed that the matches began with an inquiry into the specific features of the opponent's play. This was followed by reproducing the actions identified as effective during the inquiry. The results are discussed in relation to the role of training in expert performance.     

The concept of localised outdoor sports tourist systems: its application to Ardèche in south-east France

Tourism is important for many rural territories in France, notably with respect to economic development. A growing element of such tourist activity concerns outdoor sports which rely heavily on a region’s natural resources and are centred predominantly on a series of entrepreneurs and small businesses. Given the importance of tourism to local economies, a fuller understanding of the nature and operational characteristics of these enterprises, and of their relationship with other local actors, is essential to ensure their future development. With this objective, this paper aims to explore and evaluate the emergence of ‘localised tourist systems’ and the adaptation of this concept to outdoor sports. By using a systems approach, emphasis is given to analysing the interplay between different actors in the public, private and associative sectors and the mutual benefits that derive from such collaboration. Using evidence from the region of Ardèche in south-east France, it is argued that outdoor sports entrepreneurs form part of a ‘localised outdoor sports tourist system’ which provides added-value to the activities of these enterprises and to local institutional actors and the means to create a competitive advantage for the region’s tourist development. Future research might usefully explore in more detail the relative strength of linkages between the different actors.     

Post-exercise ingestion of a unique, high molecular weight glucose polymer solution improves performance during a subsequent bout of cycling exercise

The aim of the present study was to determine the effect of post-exercise ingestion of a unique, high molecular weight glucose polymer solution, known to augment gastric emptying and post-exercise muscle glycogen re-synthesis, on performance during a subsequent bout of intense exercise. On three randomized visits, eight healthy men cycled to exhaustion at 73.0% (s = 1.3) maximal oxygen uptake (90 min, s = 15). Immediately after this, participants consumed a one-litre solution containing sugar-free flavoured water (control), 100 g of a low molecular weight glucose polymer or 100 g of a very high molecular weight glucose polymer, and rested on a bed for 2 h. After recovery, a 15-min time-trial was performed on a cycle ergometer, during which work output was determined. Post-exercise ingestion of the very high molecular weight glucose polymer solution resulted in faster and greater increases in blood glucose (P < 0.001) and serum insulin (P < 0.01) concentrations than the low molecular weight glucose polymer solution, and greater work output during the 15-min time-trial (164.1 kJ, s = 21.1) than both the sugar-free flavoured water (137.5 kJ, s = 24.2; P < 0.05) and the low molecular weight glucose polymer (149.4 kJ, s = 21.8; P < 0.05) solutions. These findings could be of practical importance for athletes wishing to optimize performance by facilitating rapid re-synthesis of the muscle glycogen store during recovery following prolonged sub-maximal exercise.     

Practical precooling: effect on cycling time trial performance in warm conditions

The purpose of this study was to compare the effects of two practical precooling techniques (skin cooling vs. skin + core cooling) on cycling time trial performance in warm conditions. Six trained cyclists completed one maximal graded exercise test (VO2(peak) 71.4 +/- 3.2 ml x kg(-1) x min(-1)) and four approximately 40 min laboratory cycling time trials in a heat chamber (34.3 degrees C +/- 1.1 degrees C; 41.2% +/- 3.0% rh) using a fixed-power/variable-power format. Cyclists prepared for the time trial using three techniques administered in a randomised order prior to the warm-up: (1) no cooling (control), (2) cooling jacket for 40 min (jacket) or (3) 30-min water immersion followed by a cooling jacket application for 40 min (combined). Rectal temperature prior to the time trial was 37.8 degrees C +/- 0.1 degrees C in control, similar in jacket (37.8 degrees C +/- 0.3 degrees C) and lower in combined (37.1 degrees C +/- 0.2 degrees C, P < 0.01). Compared with the control trial, time trial performance was not different for jacket precooling (-16 +/- 36 s, -0.7%; P = 0.35) but was faster for combined precooling (-42 +/- 25 s, - .8%; P = 0.009). In conclusion, a practical combined precooling strategy that involves immersion in cool water followed by the use of a cooling jacket can produce decrease in rectal temperature that persist throughout a warm-up and improve laboratory cycling time trial performance in warm conditions.     

Effects of crowd size on referee decisions: analysis of the FA Cup

Data were collected on the number of first yellow cards awarded during 857 games, over six seasons (1996 - 2002), played in the Football Association (FA) Cup. Overall, a significantly higher number of yellow cards were awarded against the away team, while a non-linear relationship between crowd size and yellow cards was observed. In general, the probability of a yellow card being awarded against the home team decreased as crowd size increased, but was attenuated for the largest crowd sizes. Crowd size may be related to the probability of the home team receiving a yellow card in two potential ways. Crowd noise may be a decision-making heuristic whereby the likelihood that an incident is a foul is increased when accompanied by crowd noise. Alternatively, referees may seek to appease the crowd and are more likely to do so as crowd size increases. The present findings have implications for the training of match officials and for coaches and players as they prepare to play away from home.     

Fast bowling arm actions and the illegal delivery law in men's high performance cricket matches

This study investigated the bowling arm kinematics of 21 elite fast bowlers (mean +/- SD; age = 27.8 +/- 3.9 years) while performing in test, tour and one day international matches. Thirty-one of the 34 deliveries analysed exhibited straightening at the elbow joint (straightening min = 3 degrees, max = 22 degrees, mean +/- SD = 9 +/- 5 degrees), which by strict definition in the 2000 laws of cricket made them illegal. Five deliveries from three bowlers exhibited hyperextension of the bowling elbow (19 +/- 5 degrees). When assessed against an arbitrary threshold of 15 degrees for elbow straightening, ball speeds for deliveries above this threshold (39.5 +/- 2.0 m/s) were significantly faster (effect size = 1.4; p = 0.006) than deliveries below it (37.1 +/- 1.4 m/s). When grouped by delivery length, the bouncers and short deliveries recorded more elbow straightening (12 +/- 6.6 degrees) than the good length deliveries (9 +/- 4.4 degrees) and the full deliveries (8 +/- 5.7 degrees), although these were not statistically significant differences. The results of this study support the implementation of a tolerance threshold for assessing the legality of fast bowling actions. Further research is recommended into in-match kinematic modelling, laboratory based assessments of illegal bowling actions, perceptual aspects of bowling actions and remedial methods to reduce elbow straightening in bowling actions.     

Munchausen by Proxy in an international context

OBJECTIVE: The professional literature on Munchausen by Proxy (MBP) abuse consists of more than 400 articles, chapters, and books. Most have come from a handful of English-speaking industrialized countries. Our aims were to establish the extent to which published work about MBP has emerged from outside these countries, and to determine the characteristics of any reported cases. METHOD: Numerous health care computer databases were queried, and the results supplemented by materials accumulated less formally. RESULTS: We identified 59 articles from 24 countries describing at least 122 cases in 9 different languages. Among cases in which the information was available, the mother was the sole perpetrator in 86%, the victim was aged between 3 years and 13 years in 52%, and the victim was male in 54%. The presentations of MBP appear to be similar across the world with the exception of induced apnea, which emerged as notably uncommon in this review. An extensive table presents the characteristics of each case. CONCLUSIONS: MBP clearly is not a phenomenon unique to Western or highly medicalized societies. This form of abuse is being increasingly recognized and reported throughout the world. The literature from the US, Canada, UK, Australia, and New Zealand often presupposes access to resources, such as subspecialists and social service agencies, that may be seriously constrained in other countries. The contributions of professionals elsewhere will be vital in ensuring that the efforts in English-speaking industrialized settings to develop standards of care encompass an international perspective.     

About Face: The Rebirth of the Portrait Gallery in the Twenty‐first Century

Abstract Given the Victorian origins of the idea of a national portrait gallery, how relevant are such institutions today? The rebirth of the National Portrait Gallery in Washington, D.C. has involved a reinvestigation of notions of greatness, national identity, and the ongoing vitality of portraiture as an artistic form. Who should be deemed crucial to the telling of our national history? The evolution of thinking in our own day about the nature of national identity has undergone a dramatic shift. We have made decisions that might curl a Victorian's toes.
