Transsexuals in Sport–Fairness and Freedom,Regulation and Law

The question of if, and under what conditions transsexuals should be allowed to participate in sports in their acquired sex is becoming increasingly relevant partly because the number of transsexuals is increasing partly because many countries now provide mechanisms for achieving legal recognition as belonging to the new acquired sex. This paper develops (1) an analysis of the justification for maintaining sex segregation in some sports and (2) an account of the rights of transsexuals to be recognised in their new sex. On the basis of these two analyses it critically evaluates two set of rules for the participation of transsexuals in elite sports: the UK guidelines issued in pursuance of the Gender Recognition Act 2004 and the International Olympic Committee's guidelines. It is argued that these guidelines are conflicting and that a modified set of criteria is more justifiable.     

An Evolutionary Approach to Revising Modernization Theory: An Introduction to the Credible Polity

The future global distribution of the political regimes of countries, just like that of their economic incomes, displays a surprising tendency for polarization into only two clubs of convergence at the extrema. This, in itself, is a persuasive reason to analyze afresh the logical validity of an endogenous theory for political and economic development inherent in modernization theory. I suggest how adopting a simple evolutionary game theoretic view on the subject allows an explanation for these parallel clubs of convergence in political regimes and economic income within the framework of existing research in democratization theory. I also suggest how instrumental action can be methodically introduced into such a setup using learning strategies adopted by political actors. These strategies, based on the first principles of political competition, are motivated by introducing the theoretical concept of a Credible Polity.     

Engaging Environments Enhance Motor Skill Learning in a Computer Gaming Task

Engagement during practice can motivate a learner to practice more, hence having indirect effects on learning through increased practice. However, it is not known whether engagement can also have a direct effect on learning when the amount of practice is held constant. To address this question, 40 participants played a video game that contained an embedded repeated sequence component, under either highly engaging conditions (the game group) or mechanically identical but less engaging conditions (the sterile group). The game environment facilitated retention over a 1-week interval. Specifically, the game group improved in both speed and accuracy for random and repeated trials, suggesting a general motor-related improvement, rather than a specific influence of engagement on implicit sequence learning. These data provide initial evidence that increased engagement during practice has a direct effect on generalized learning, improving retention and transfer of a complex motor skill.     

When happiness makes us selfish, but sadness makes us fair: Affective influences on interpersonal strategies in the dictator game

Does temporary mood influence how fair or selfish we are in interpersonal situations? These three experiments predicted and found that when people have the power to allocate scarce resources between themselves and others in the dictator game, positive mood increased selfishness, and sad mood produced greater fairness. In a public setting (Experiment 1), happy persons kept more raffle tickets to themselves when making allocations, and Experiment 2 confirmed this effect in the laboratory. Experiment 3 showed that mood effects on selfishness were strongest when the external norms for fairness were relaxed. The results are discussed in terms recent affect-cognition theories, suggesting that positive mood recruits more assimilative, internally focused processing, while negative affect promotes more externally oriented, accommodative processing and thus greater concern with social norms. The implications of the findings for everyday interpersonal decisions are considered.     

Media violence and the self: The impact of personalized gaming characters in aggressive video games on aggressive behavior

A recent development in video games is that players can design and personalize their own in-game characters. It was predicted that this innovation could lead to elevations in the intensity of the psychological effects of video games. The present study confirmed this hypothesis, revealing that participants who played an aggressive video game using their own, personalized character exhibited higher levels of aggressive behavior than participants who played an aggressive game with a non-personalized character. The aggressive behavior levels of the own-character players also exceeded those of individuals who played a non-aggressive game, regardless of whether or not they used a personalized character. Process analyses revealed that participants playing a violent video game with a personalized game character experienced more arousal and self-activation than they did when playing with an impersonal, default game character, which in turn increased aggressive responses.     

The influence of the Chinese sport system and Chinese cultural characteristics on Olympic sport psychology services

ObjectivesThe purpose of this study was to investigate the influence of sociocultural factors on Chinese Olympic sport psychology services.Design and methodsFifteen sport psychology consultants (SPCs), who served Chinese national teams for the 2008 Beijing Olympic Games, participated in this study after the Olympics. Semi-structured interviews were conducted within three months of the closing of the Olympics, followed by a hybrid approach to inductive and deductive thematic analyses.ResultsTwo general dimensions of sociocultural influence on Chinese Olympic sport psychology services were identified: (a) the Whole-Nation System and (b) Chinese cultural characteristics. They consisted of eight higher order themes, which comprised 26 lower order themes. This study revealed that Chinese sport psychology services were enhanced by recognizing the features of the Whole-Nation System (e.g., resource centralization and top-down management) and the successful blending of these features with Chinese cultural characteristics (e.g., holistic thinking style, keeping face and interpersonal order) into the psychological service.ConclusionsSociocultural factors had a marked influence on Chinese Olympic sport psychology services, which enabled Chinese SPCs to provide a culturally competent service (e.g., prioritizing collective interests, respecting the authority of administrative officials and coaches, and keeping face with others) for the Beijing Olympic Games.     

The expressibility of fragments of Hybrid Graph Logic on finite digraphs

Hybrid Graph Logic is a logic designed for reasoning about graphs and is built from a basic modal logic, augmented with the use of nominals and a facility to verify the existence of paths in graphs. We study the finite model theory of Hybrid Graph Logic. In particular, we develop pebble games for Hybrid Graph Logic and use these games to exhibit strict infinite hierarchies involving fragments of Hybrid Graph Logic when the logic is used to define problems involving finite digraphs. These fragments are parameterized by the quantifier-rank of formulae along with the numbers of propositional symbols and nominals that are available. We ascertain exactly the relative definability of these parameterized fragments of the logic.
