Quand Bradley Manning devint Chelsea. De la NBC à Wikipédia, l'espace public comme scène d'une transition de genre

Scène de phénoménalisation de Chelsea Manning, l'espace public est aussi son lieu de naissance. En effet, le 22 août 2013, Bradley Manning, ex-analyste du renseignement en Irak alors incarcéré dans une prison militaire américaine pour avoir délivré des documents confidentiels à WikiLeaks, fait savoir dans un communiqué de presse remis à la NBC qu'il se sent avoir toujours été une femme. Il demande également à être désigné désormais sous le prénom de « Chelsea ». Cette auto-déclaration identitaire de genre est en réalité proférée par la journaliste du Today Show, lors de l'entretien qu'elle mène avec l'avocat de Manning. Une fois la demande transmise, la journaliste et l'avocat se réfèrent à Manning au féminin. C'est ainsi qu'un plateau de télévision s'est transformé en la scène d'une transition de genre. Mais l'annonce de Manning a eu des effets, durables, bien au-delà de cette scène locale. Ainsi, au sein de la scène globale qu'est l'encyclopédie en ligne Wikipédia, les contributeurs ont débattu, parfois avec acharnement, de l'opportunité de renommer la page de l'article intitulé « Bradley Manning » pour consacrer sa féminité nouvellement acquise. Sur la base d'une analyse énonciative, notre article montre comment le Today Show du 22 août 2013 a transformé la déclaration de Manning en un performatif. Restituant la trajectoire d'(in)félicité de ce performatif, il s'attache également à ethnographier les pages « discussion » de la Wikpédia anglophone et francophone.

Managing the size of the Olympic Games

The last two decades have seen dramatic increases in the size and scope of the Summer Olympic Games. In many ways, London 2012 reached even higher summits than the Beijing Games in 2008. This growth is a major challenge for the Olympics and its future organizers, as it is making the Games increasingly difficult to stage and has greatly reduced the number of cities capable of hosting them. This study shows how various participation and organization indicators have expanded over six Olympiads, from Barcelona 1992 to London 2012, and examines the reasons for this growth. It suggests ways of reducing the size of the Summer Olympic Games in order to make them more manageable and to encourage candidatures from smaller cities and countries.

Spectators play a fundamental role in sports events because they co-create value with the athletes, and they can provide substantial revenues for the organisers. This is even more the case for the Olympic Games, as was strikingly illustrated by London 2012. Although most people see the Games on television, the Olympics need large numbers of flesh-and-blood spectators and fans to encourage and applaud the Olympians and to create the festive atmosphere that is such an important part of Olympic competitions. Spectators can transform simple sporting competitions between athletes into spectacles that generate strong emotions. In the arena provided by the organisers, they create with the athletes an event that is worthy of being reported by the media. Coubertin was himself convinced that knowledgeable spectators are essential to obtaining high levels of performance, while regretting that stadiums had (already) become too big (Coubertin 2000: 184 and 199).

Consensus recommendations on training and competing in the heat.

Exercising in the heat induces thermoregulatory and other physiological strain that can lead to impairments in endurance exercise capacity. The purpose of this consensus statement is to provide up-to-date recommendations to optimize performance during sporting activities undertaken in hot ambient conditions. The most important intervention one can adopt to reduce physiological strain and optimize performance is to heat acclimatize. Heat acclimatization should comprise repeated exercise-heat exposures over 1-2 weeks. In addition, athletes should initiate competition and training in a euhydrated state and minimize dehydration during exercise. Following the development of commercial cooling systems (e.g., cooling vest), athletes can implement cooling strategies to facilitate heat loss or increase heat storage capacity before training or competing in the heat. Moreover, event organizers should plan for large shaded areas, along with cooling and rehydration facilities, and schedule events in accordance with minimizing the health risks of athletes, especially in mass participation events and during the first hot days of the year. Following the recent examples of the 2008 Olympics and the 2014 FIFA World Cup, sport governing bodies should consider allowing additional (or longer) recovery periods between and during events for hydration and body cooling opportunities when competitions are held in the heat.
