Mutated bodies: stage performances of Beckett's late prose texts by Mabou Mines (1984) and Gare St. Lazare Players, Ireland (2005)

An exploration of the stage adaptations of Beckett's fictional texts by the New York based Mabou Mines theatre company.

Information and efficiency: goal arrival in soccer betting

An efficient market incorporates news into prices immediately and fully. Tests for efficiency in financial markets have been undermined by information leakage. We test for efficiency in sports betting markets – real-world markets where news breaks remarkably cleanly. Applying a novel identification to high-frequency data, we investigate the reaction of prices to goals scored on the ‘cusp’ of half-time. This strategy allows us to separate the market's response to major news (a goal), from its reaction to the continual flow of minor game-time news. On our evidence, prices update swiftly and fully.

Technical variation in a sample of high level judo players

Technical actions performed by two groups of judokas who won medals at World Championships and Olympic Games during the period 1995-2001 were analyzed. In the Super Elite group (n = 17) were the best athletes in each weight category. The Elite group (n = 16) were medal winners who were not champions and did not win more than three medals. Super Elite judokas used a greater number of throwing techniques which resulted in scores, even when expressed relative to the total number of matches performed, and these techniques were applied in more directions than those of Elite judokas. Further, the number of different throwing techniques and the variability of directions in which techniques were applied were significantly correlated with number of wins and the number of points and ippon scored. Thus, a greater number of throwing techniques and use of directions for attack seem to be important in increasing unpredictability during judo matches.

Kartläggning av tillslagsprecision i fotboll

Syfte Syftet med studien är att analysera tillslagsprecision i fotboll och jämföra eventuella skillnader mellan juniorer och seniorer på både herr- och damsidan. Metod Totalt 30 elitspelare varav 16 herrar och 14 damer utförde tester i tillslagsprecision. De färdigheter som testades var passning och skott. Upplägget var 60 skott (30 stillaliggande och 30 halvvolley) och 80 passningar (20 stillaliggande bästa fot, 20 rullande bästa fot, 20 stillaliggande näst bästa fot och 20 rullande näst bästa fot). Testresultaten analyserades via Excel och Kinovea, där kunde medelvärden och standardavvikelser för varje testperson och testgrupp räknas ut. Resultat Resultatet visar att det endast var signifkant skillnad på ett av sex moment vad gäller tillslagsprecisionen på herrsidan. På damsidan var det ingen signifikant skillnad på något moment. Slutsatser Författarna har i denna studie identifierat en platå mellan spelare i åldrarna 16-18 år och seniorspelare vad gäller tillslagsprecision. Spelare i åldrarna 16-18 är lika bra som seniorspelare på de individuella färdigheterna passning och skott. Denna platå kan vara resultatet av för lite individuell träning, sk isolerad träning vad det gäller tillslagsprecision, på föreningsträningarna. Om föreningstränarna följer den utbildning SvFF ger dem ska endast två minuter per träning gå till varje individuell färdighet (13 st enligt SvFF). Bristen av tid för dessa färdigheter kan vara en avgörande faktor för att utvecklingen av tillslagsprecision står stilla idag.

Beyond indifferent players: on the existence of prisoners dilemmas in games with amicable and adversarial preferences

Why don’t agents cooperate when they both stand to gain? This question ranks among the most fundamental in the social sciences. Explanations abound. Among the most compelling are various configurations of the prisoner’s dilemma (PD), or public goods problem. Payoffs in PD’s are specified in one of two ways: as primitive cardinal payoffs or as ordinal final utility. However, as final utility is objectively unobservable, only the primitive payoff games are ever observed. This paper explores mappings from primitive payoff to utility payoff games and demonstrates that though an observable game is a PD there are broad classes of utility functions for which there exists no associated utility PD. In particular we show that even small amounts of either altruism or enmity may disrupt the mapping from primitive payoff to utility PD. We then examine some implications of these results.

Sports administration: an examination of the competitive balance concept through european and brazilian domestic soccer leagues comparison

A questão do Equilíbrio Competitivo é um tema importante da economia dos esportes profissionais nos Estados Unidos e na Europa. Muitas pesquisas foram feitas para estabelecer os critérios mais relevantes para avaliar a competitividade das ligas profissionais de futebol. Esta pesquisa analisou a relevância do Equilíbrio Competitivo como determinante da competitividade comparando o Brasileirão Série A com as nove principais ligas na Europa (Bélgica, Inglaterra, Alemanha, Holanda, França, Itália, Portugal, Escócia e Espanha). A competitividade é a capacidade de uma empresa (um clube) ou de uma indústria de enfrentar a concorrência efetiva ou potencial. A medida da competitividade deve levar em consideração uma série de fatores importantes como a qualidade e a relação qualidade/preço, a gestão de recursos humanos e a organização empresarial. Esse trabalho visa demonstrar que, apesar da incerteza do resultado ter sido considerado por muito tempo como um fator positivo de atratividade/interesse dos fãs nos esportes, um campeonato equilibrado poderia ter um efeito insignificante, para não dizer desprezível sobre a competitividade das ligas de futebol a longo prazo. Os resultados mostraram que o aumento do Equilíbrio Competitivo pode ser relevante para os campeonatos mais fracos (Bélgica, Holanda, Portugal, Escócia), mas nao dos cincos melhores (Alemanha, Espanha, França, Inglaterra, Itália). Consequentemente, o Equilíbrio Competitivo deve ser contemplado como uma variável desprezível quanto à competitividade das ligas de futebol, apesar do interesse crescente pelo conceito na literatura. Baseado principalmente em pesquisas de Dell'Osso e Symanski (1991) e de Oughton e Michie (2004), o índice HHI (Herfindahl-Hirschman) tem sido utilizado para determinar o nível de concentração de 11 ligas de futebol estudadas. Uma revisão da literatura sobre administração de futebol e esportes foi realizada.

A new playing field: retrospective voting and soccer in Brazil

O propósito deste estudo é analisar o possível impacto que um viés emocional possa ter nos julgamentos dos eleitores. Nesse sentido utilizamos o futebol como fonte exógena de um choque. O nosso modelo de efeitos fixos nos leva a concluir que vitórias de equipes no final de semana da eleição estão associadas a maior votação no incumbente indicando que um viés emocional pode influenciar o eleitor.
