EI caso espanol de dopaje conocido como "Operaci6n Puerto" queda enmarcado dentro del
abandono de las antiguas concepciones legales y la construcci6n de un nuevo sistema funcional de alcance global. "Operaci6n Puerto" ilustra el temor de Verner Moeller de que la politica anti dopaje senala el final de la modernidad - donde se elabora y aplica la ley tanto en los tribunales como en los medios de comunicaci6n. OP es el ejemplo perfecto de la distancia existente entre la ret6rica de la crisis mediatica que rodea al dopaje y al ciclismo profesional y la verdadera realidad de los procesos materiales que tienen lugar mientras el ciclismo atraviesa por un proceso global de reajuste estructural y de construcci6n de una nueva cartografla global del ciclismo. La legitimidad se obtiene a traves de la gesti6n de las crisis y de los acontecimientos: la excepci6n, la funcionalidad y el espectaculo bajo una apariencia de guerra justa contra el mal del dopaje

This paper describes the construction of the visual space of surveillance by the global anti-doping apparatus, it is a space inhabited daily by professional cyclists. Two principal mechanisms of this apparatus will be discussed—the Whereabouts System and the Biological Passport; in order to illustrate how this space is constructed and how it visualises the invisible act of doping. These mechanisms act to supervise and govern the professional cyclist and work to classify them as either clean or dirty in terms of the use of prohibited doping substances or methods. Contrary to the analysis of liberal anti-doping scholars such as Hanstad, Loland and Møller this paper argues that Foucault’s Panopticon paradigm is a useful tool for the analysis of this apparatus. The Whereabouts System and Biological Passport are the instruments by which the anti-doping apparatus intensifies the construction of the space of surveillance in professional sport. This space of surveillance not only locates and makes visible the physical location of each individual cyclist, but it also makes visible their internal bodily functions, in this case the composition and the fluctuations of the composition of their blood. In making the cyclist visible the instruments do not allow the cause of doping, or the event of doping to be known or observed. Rather what they do is cast the body in terms of abnormalities of time, place or blood. In the case of an abnormality of the cyclist’s blood, the cause itself cannot be identified with any certainty, all that is made visible is a suggestion, or a probability, that doping may have occurred. The ultimate effects are twofold—an internalisation and continual monitoring of one’s self as well as by the authorities, and a radical change in the nature and the definition of the offence of doping. No longer is it positive evidence of doping that is punishable, but what becomes punishable is an abnormality, in the cyclist’s location, or their body, which suggests a probability that the invisible act of doping may have occurred. In the course of this process accepted manners of proving an offence by the use of scientific evidence and expert commentary are transformed. The Whereabouts System and the Biological Passport open up a new manner in which the invisible can be visualised. Through the discourse and the attendant commentary of the expert a new alliance between doping and the law is constructed. The result is a redistribution of the way in which the law visualises and treats the symptoms (the signifier) and the signified act of doping.

 Through a study of the global anti-doping apparatus and professional cycling this thesis concerns how law and governance is changing in the global context and how these changes are inherent to broader processes associated with neoliberalism and affecting all aspects of society.

This article describes the utilisation of an unsupervised machine learning technique and statistical approaches (e.g., the Kolmogorov-Smirnov test) that assist cycling experts in the crucial decision-making processes for athlete selection, training, and strategic planning in the track cycling Omnium. The Omnium is a multi-event competition that will be included in the summer Olympic Games for the first time in 2012. Presently, selectors and cycling coaches make decisions based on experience and intuition. They rarely have access to objective data. We analysed both the old five-event (first raced internationally in 2007) and new six-event (first raced internationally in 2011) Omniums and found that the addition of the elimination race component to the Omnium has, contrary to expectations, not favoured track endurance riders. We analysed the Omnium data and also determined the inter-relationships between different individual events as well as between those events and the final standings of riders. In further analysis, we found that there is no maximum ranking (poorest performance) in each individual event that riders can afford whilst still winning a medal. We also found the required times for riders to finish the timed components that are necessary for medal winning. The results of this study consider the scoring system of the Omnium and inform decision-making toward successful participation in future major Omnium competitions.

This project explores the potential of electronic communications to support peer-to-peer interaction between separate whole-school communities as a means of providing both authentic, situated, professional development for teachers, concurrent with the development of enhanced student learning outcomes, and the intentional sharing of school 'culture'.  The intense use of telecommunications by both teacher and students in a 'many-to-many' manner provides rich opportunities for teachers to rethink their pedagogy, reconceptualise their classroom culture, and for students to see teachers as learners 'in situ'.  An extensive trial between two schools some 120km apart has demonstrated the basic functionality of the model.  This paper discusses the origins of the project, findings from the trial, and the nature of the changes to be made to the model to enhance its effects.

Previous studies looking at the sources of stress in sport have generally overlooked the unique experiences of professional athletes participating in team sports. This paper describes the results of a qualitative study aimed at identifying the sources of stress experienced by a cross-section of professional Australian footballers. Players from two Australian Football League clubs took part in the study involving in-depth, one-to-one interviews and focus group discussions. The results revealed that players identified sources of stress that went beyond those associated with the competitive event (such as poor performances) and included a lack of feedback, difficulty balancing football and study commitments, and job insecurity. The influence of both competition and non-competition sources of stress parallels previous research involving non-professional athletes and indicates that the entire sporting experience needs to be taken into account when developing stress management strategies.

We have estimated the reliability of performance in a commonly employed exercise test consisting of repeated sprints on a cycle ergometer. Eight recreationally active young men completed a practice trial and three more trials at 3- to 6-day intervals. Each trial consisted of two bouts of 30-s maximal-effort cycling on an electromagnetically braked cycle ergometer; the bouts were separated by 4 min of rest. The typical (standard) errors of measurement for peak and mean power between trials 2 to 4 were 2.5 and 1.7% respectively for the first bout and 1.9 and 1.8% for the second bout. These errors are substantially less than those in previous reliability studies of single 30-s sprint tests, probably because of differences in quality of ergometer. The typical errors for the difference between bouts (i.e., fatigue) for peak power and mean power were 3.0 and 2.5%, respectively. Typical errors for the average of the two bouts were 1.6 and 1.2% for peak and mean power respectively, which are small enough to give adequate precision for moderate treatment effects in studies with modest sample sizes.

The aim of the present study was to determine the influence of pedal rate on the precision and quantification of the accumulated oxygen deficit (AOD). Eight trained male triathletes completed a lactate threshold test, VO2 peak test, 10 x 3 min submaximal exercise bouts and a high-intensity exercise bout, all performed at 80 and 120 rev/min. For both pedal rates the intensities for the sub-maximal and high-intensity tests were relative to the lactate threshold and VO2 peak work rates. The VO2-power regressions were calculated using 5 intensities from above the lactate threshold combined with a y intercept value with VO2 measured after 3 min of exercise. For the 120 compared to the 80 rev/min tests, the lactate threshold work rate (255±13 versus 276±47 Watts) (p<0.01) and VO2 peak work rate (352±17 versus 382±20, Watts) (p<0.05) were lower at 120 rev/m. Conversely, the VO2 peak and the VO2 measured during the exhaustive exercise were the same for both pedal rates (p>0.05). Using linear regression modelling the slope of the VO2-power regression (0.0112 versus 0.010 L/Watt) (p<0.01), the estimated total energy demand (ETED) (5.13±0.75 versus 4.89±0.88 L/min) and the AOD (4.27±0.94 versus 3.66±1.25 L) (p<0.05) were greater at 120 rev/m. However, the 95% confidence interval for the ETED and the standard error of the predicted value were the same for both pedal rates (p>0.05). Our results demonstrate that pedal rate effects the size but not the precision of the calculated AOD and should therefore be considered when developing an AOD protocol.

A transformational model of professional identity formation, anchored and globalized in workplace conversations, is advanced. Whilst the need to theorize the aims and methods of clinical education has been served by the techno-rational platform of 'reflective practice', this platform does not provide an adequate psychological tool to explore the dynamics of social episodes in professional learning and this led us to positioning theory. Positioning theory is one such appropriate tool in which individuals metaphorically locate themselves within discursive action in everyday conversations to do with personal positioning, institutional practices and societal rhetoric. This paper develops the case for researching social episodes in clinical education through professional conversations where midwifery students, in practice settings, are encouraged to account for their moment-by-moment interactions with their preceptors/midwives and university mentors. It is our belief that the reflection elaborated by positioning theory should be considered as the new epistemology for professional education where professional conversations are key to transformative learning processes for persons and institutions.

Cheating, it is claimed, is anathema to sport. But is this the case? In this paper it is argued that cheating is integral to modern sport, that the model of sport as 'fair play' is simply an ideological guise of amateurism. The paper focuses on the sport of professional running which, since its origins in the eighteenth century, has been a gambling sport. Strategies involving cheating to manipulate wins, or losses, have featured in this sport as ways of increasing the probability of striking successful wagers. Such strategies are an accepted part of professional running: participants anticipate and expect others to be playing it in this way. However, a distinction is made between what is referred to in the paper as 'clean' cheating and 'dirty' cheating. The former is an accepted way of the sport, the latter occurs but is deprecated. The paper explores these different forms of cheating and the athletes' responses to them. Through a focus on the discourses of success in capitalist society, a model of cheating is developed to interpret such practices. Within the context of professional running, a working class sport, it is argued that, given the habitus of its practitioners, 'success' may be measured in terms of monetary gains and the 'kick-on' in life that these might provide. Cheating practices may serve to enhance the probability of success and social mobility. Given the relatively short career spans of sports people and the costs involved in developing the requisite skills, cheating may promote success and establish a financial base for post-sport careers. The paper concludes that cheating in sport can be anticipated as a feature of an acquisitive capitalist society.
