Pédiatrie. (2.) Consultation de médecine du sport dédiée à l'adolescent [Sport medicine consultation for adolescents].

Sport activity is a determinant of health and well-being for adolescents' psychological and physic development. Early detection of traumatic lesions or pathological condition among sportive adolescent in the light of their developmental stage is of outmost importance and is best done by an interdisciplinary team. This clinical management also aims at preventing consequences of inappropriate training. The CHUV has set-up a specific sports medicine outpatient consultation clinic for adolescents in the order to provide the best integrative management of young athletes.

Le sport en contexte colonial et postcolonial : une historiographie en friche

Réunissant quelques-uns des meilleurs experts français sur la question, le projet de cet ouvrage est de dresser un bilan des principales orientations historiographiques de l'histoire du sport. Cette réflexion complète la table ronde organisée lors du congrès du comité français des sciences historiques (Reims 2012). Elle s'interroge sur la spécificité d'un champ qui s'est développé en marge de l'Histoire en abordant un objet - le sport - qui traverse les cultures et les périodes, et entretient avec les registres politiques, sociaux, économiques, médiatiques, ou scientifiques des liens originaux. Appuyée sur des comparaisons européennes et nordaméricaines, elle suggère aussi des perspectives et de nouvelles pistes à investiguer. Cet ouvrage constitue une base de données précieuse pour les étudiants, doctorants, enseignants, chercheurs, archivistes et conservateurs et, plus largement, tout public averti et désireux de comprendre comment l'histoire a, jusqu'ici, questionné le phénomène sportif. Le lecteur y puisera des éléments conceptuels et des points d'appui historiographiques essentiels. Les grands débats du moment s'y reflètent : sport dans l'Antiquité, histoire de l'éducation physique, histoire économique du sport, histoire des techniques, des médias, du genre, ou encore histoire du sport en milieu colonial.

Which governance for which Olympic sport organization? : a postface

This brief conclusion suggests that, although governance is an important goal for sport organizations, it must be applied by taking into consideration the type of sport organizations, in particular whether the organization is an association of moral or physical persons and whether these persons are direct beneficiaries or not of the organization.

Animal modelling for inherited central vision loss.

Disease-causing variants of a large number of genes trigger inherited retinal degeneration leading to photoreceptor loss. Because cones are essential for daylight and central vision such as reading, mobility, and face recognition, this review focuses on a variety of animal models for cone diseases. The pertinence of using these models to reveal genotype/phenotype correlations and to evaluate new therapeutic strategies is discussed. Interestingly, several large animal models recapitulate human diseases and can serve as a strong base from which to study the biology of disease and to assess the scale-up of new therapies. Examples of innovative approaches will be presented such as lentiviral-based transgenesis in pigs and adeno-associated virus (AAV)-gene transfer into the monkey eye to investigate the neural circuitry plasticity of the visual system. The models reported herein permit the exploration of common mechanisms that exist between different species and the identification and highlighting of pathways that may be specific to primates, including humans.

Development of a systematic computer vision-based method to analyse and compare images of false identity documents for forensic intelligence purposes-Part I: acquisition, calibration and validation issues

Following their detection and seizure by police and border guard authorities, false identity and travel documents are usually scanned, producing digital images. This research investigates the potential of these images to classify false identity documents, highlight links between documents produced by a same modus operandi or same source, and thus support forensic intelligence efforts. Inspired by previous research work about digital images of Ecstasy tablets, a systematic and complete method has been developed to acquire, collect, process and compare images of false identity documents. This first part of the article highlights the critical steps of the method and the development of a prototype that processes regions of interest extracted from images. Acquisition conditions have been fine-tuned in order to optimise reproducibility and comparability of images. Different filters and comparison metrics have been evaluated and the performance of the method has been assessed using two calibration and validation sets of documents, made up of 101 Italian driving licenses and 96 Portuguese passports seized in Switzerland, among which some were known to come from common sources. Results indicate that the use of Hue and Edge filters or their combination to extract profiles from images, and then the comparison of profiles with a Canberra distance-based metric provides the most accurate classification of documents. The method appears also to be quick, efficient and inexpensive. It can be easily operated from remote locations and shared amongst different organisations, which makes it very convenient for future operational applications. The method could serve as a first fast triage method that may help target more resource-intensive profiling methods (based on a visual, physical or chemical examination of documents for instance). Its contribution to forensic intelligence and its application to several sets of false identity documents seized by police and border guards will be developed in a forthcoming article (part II).

Video Gaming Disorder and Sport and Exercise in Emerging Adulthood: A Longitudinal Study.

Among the negative consequences of video gaming disorder, decreased participation in sport and exercise has received little attention. This study aimed to assess the longitudinal association between video gaming disorder and the level of sport and exercise in emerging adult men. A questionnaire was completed at baseline and 15-month follow-up by a representative national sample of 4,933 respondents. The seven items of the Game Addiction Scale were used to construct a latent variable representing video gaming disorder. Level of sport and exercise was also self-reported. Cross-lagged path modeling indicated a reciprocal causality between video gaming disorder and the level of sport and exercise, even after adjusting for a large set of confounders. These findings support the need for better promotion of sport and exercise among emerging adults in order to contribute to the prevention of video gaming disorder, and to raise the level of sport and exercise activity in addicted gamers.

Olympic social responsibility : a challenge for the future

Social responsibility, especially in the fields of education, society and peace, is one of the cornerstones of the olympic ideal and strategic vision (contribute to building a better world through sport). The article reviews the literature on organizational social responsibility (OSR) and the relationship between sport/olympism and OSR in order to examine the conditions governing the implementation and success of the International Olympic Committee's strategic vision. Several ways in which the IOC could promote a more ambitious and better-integrated social strategy: revise its performance model, notably evaluate and present in a social responsibility report; promote the adoption of OSR initiatives and strategies within the Olympic System from the bottom-up, rather than from the top-down; share best practices in the different countries for promoting and developing "sport for all"; create a World Agency for Development through Sport, or partnering and funding the international platform on sport and development; creating a World Agency for the International Governance of Sport. Two possible scenarios for the future of Olympic responsibility are finally discussed: strategy of "small steps" and a more ambitious local and global social strategy through sport and olympism.

A rationalist perspective on the autonomy of international sport governing bodies : towards a pragmatic autonomy in the steering of sports

International sport governing bodies (ISGBs) are built on the foundations of freedom of association and traditionally enjoy a large degree of autonomy in their decision-making. Their autonomy is increasingly confined, however, and their hierarchical self-governance is giving way to a more networked governance, in which different stakeholders exert power in different ways and in different contexts in a complex web of interrelationships. Taking a rationalist perspective on the autonomy of ISGBs, this article demonstrates that ISGBs are deploying strategies to safeguard their waning governing monopoly over international sport. Opting for an inductive approach, the authors present four possible conceptualizations of autonomy as applied to ISGBs, namely political autonomy, legal autonomy, financial autonomy and pyramidal autonomy. For each dimension, they describe the different strategies ISGBs wield in order to safeguard different dimensions of their autonomy. This article uses governance theories to hypothesize that the autonomy of ISGBs can be understood as 'pragmatic autonomy' since ISGBs only cede certain aspects of their autonomy under particular circumstances and when being subject to specific threats. Acting in a rationalist manner, they are able to keep control over governance developments in sport by using indirect and more subtle forms of governance.
