Sports are increasingly shaped by science and technology. Sportspersons now routinely operate in an environment consisting of devices, data flows, laboratories, and scientists. While governments, research industries, and many scientists across the world promote the integration of science and technology into sports as a means of inspiring innovation in sports, how this integration is achieved has not been systematically investigated. To remedy this shortcoming in science and technology studies (STS) and to grasp how science, technology, and sports are mutually attuned in everyday situations, this paper examines a sociotechnical device developed by scientists in Flanders (Belgium) popularly known as the ‘sports compass’ (sportkinelab.be/sportkompas). As the sports compass is designed to detect and develop sports talent in young children through standardized physical trials, it is used in the Flemish sports field. Drawing on ethnographic methods and on preliminary interviews with sports compass developers and users (scientists, children, parents), the paper argues that the compass’s solidity as a scientific conduit for talent is disrupted by the multiple social aims it serves (e.g. sports participation, striving for excellence) and the multiple expectations it elicits. Accordingly, multiple solidarities and shifting alliances can be discerned between technology developments and uses, devices and humans, and between research institutes, schools, and sports organizations. The paper’s findings serve to open a discussion both on the meaning and viability of talent detection among children and sportspersons, and on sports and innovation policies designed to render sports more scientific and technological.

La crise actuelle du virus Ebola en Afrique de l’Ouest qui a probablement commencé en Guinée en décembre 2013 (Baize et al., 2014) progresse maintenant de manière fulgurante. Le 14 septembre 2014, cinq pays étaient officiellement touchés: Liberia, Guinée, Sierra Leone, Nigeria et Sénégal. Le nombre total de cas recensés était alors de 5357, dont 2630 ont mené au décès des malades. Près de 45% des cas recensés d’Ebola ont été dénombrés au cours des trois dernières semaines (WHO, 2014).

At any point in time, human performance results from the interaction of two main factors: a circadian signal varying with the time of the day and the sleep need accrued throughout the preceding waking period. But what’s happen at the cortical cerebral level? We used a novel technique coupling transcranial magnetic stimulation with electroencephalography (TMS/EEG) to assess the influence of time spent awake and circadian phasis on human cortical excitability. Twenty-two healthy young men underwent 8 TMS/EEG sessions during a 28 hour sleep deprivation protocole. We found that cortical excitability depends on both time spent awake and circadian phasis.

This presentation highlights the last reflections of the author on NWM in Belgium. It focuses on the new governance practices in Belgian nuclear waste management (NWM) from its ‘participatory turn’ in the late 1990s. Rather than praising (or rejecting) participation versus expert analysis, we make use of a theoretical and analytical framework in which the important dynamics for the analysis are ‘opening up’ and ‘closing down’ technological appraisals and commitments. Even though NWM agencies often plea for an integrative approach between experts analysis and participation, in practice this reveals itself rather complicated as both exercises are often kept separate. We address this separation and its consequences and we find that societal concerns remain subsumed in the technical options which have long been favoured by the Belgian agency. This taming of uncertainty may come at a high price, if it systematically reduces the scope of alternative options for governance intervention or if societal consultations ultimately appear like an instrument of legitimation of already-taken decisions.

Background and purpose Patients may experience clinically relevant anxiety at their first radiotherapy (RT) sessions. To date, studies have not investigated during/around the RT simulation the key communication and communication-related predictors of this clinically relevant anxiety. Material and methods Breast cancer patients (n = 227) completed visual analog scale (VAS) assessments of anxiety before and after their first RT sessions. Clinically relevant anxiety was defined as having pre- and post-first RT session VAS scores ⩾4 cm. Communication during RT simulation was assessed with content analysis software (LaComm), and communication-related variables around the RT simulation were assessed with questionnaires. Results Clinically relevant anxiety at the first RT session was predicted by lower self-efficacy to communicate with the RT team (OR = 0.65; p = 0.020), the perception of lower support received from the RT team (OR = 0.70; p = 0.020), lower knowledge of RT-associated side effects (OR = 0.95; p = 0.057), and higher use of emotion-focused coping (OR = 1.09; p = 0.013). Conclusions This study provides RT team members with information about potential communication strategies, which may be used to reduce patient anxiety at the first RT session. [less ▲]

The University of Liège Library's books collection is composed of some 2,000,000 print volumes, of which only 60% are catalogued. Most of the uncatalogued books have been published before 1970 and cataloguing these according usual standards and norms would certainly take decades. To decrease the cost of treatments and increase the number of catalogued volumes, the Library developed a light PHP/MySQL application, Scriptorium, that enables non-catalogers (mostly students) to quickly encode the books (ca 3 min. per item) by providing the most essential information. References are then daily exported in MarcXML to the ILS. Scriptorium has been developed to permit to easily create new independent instances for different parallel retro-cataloguing projects and also to be used by other libraries. [less ▲]

Etant donné que le vieillissement normal s’accompagne d’un déclin de la recollection tandis que la familiarité reste préservée, les tâches mnésiques facilitant l’utilisation de la familiarité permettraient de réduire les différences liées à l’âge en mémoire épisodique. Cette étude a évalué deux questions : 1) L’utilisation de la familiarité en reconnaissance peut-elle être favorisée en augmentant la différence de facilité de traitement perceptif (fluence) entre les items étudiés et les nouveaux items ? ; 2) Cette manipulation permet-elle de réduire l’effet de l’âge ? Deux tâches de reconnaissance ont été proposées à 24 participants jeunes et 24 participants âgés. Dans une tâche « sans recouvrement », les mots cibles et les mots nouveaux ne possédaient aucune lettre commune. L’exposition préalable aux mots cibles induisait donc une fluence sur les mots, mais également sur les lettres de sorte que la différence de fluence devenait un indice saillant et fiable pour distinguer cibles et distracteurs. Dans une tâche « avec recouvrement », les mots cibles et les mots nouveaux contenaient des lettres communes. Les résultats ont répliqué l’effet de l’âge sur la recollection (réponses Remember), avec préservation de la familiarité (réponses Know). Par ailleurs, nous observons 1) une amélioration de la discrimination dans la tâche « sans recouvrement », avec un plus grand nombre de reconnaissances correctes et moins de fausses reconnaissances (les deux basés sur la familiarité). De plus, 2) les différences liées à l’âge dans la capacité à discriminer cibles et distracteurs (reconnaissances correctes - fausses reconnaissances) étaient significativement réduites dans la tâche sans recouvrement par rapport à la tâche avec recouvrement. Ces données suggèrent que minimiser la similarité perceptive entre les mots cibles et les mots distracteurs, et donc augmenter la fluence, permet de réduire les différences liées à l’âge en reconnaissance en facilitant l’utilisation de la familiarité.

A general physically based method is presented to assess vulnerability of groundwater to external pressures with respect to quality and/or quantity issues. In the vulnerability assessments, many scientific authors agree nowadays that ‘physically based’ methods must be preferred to traditional approaches based on empirical overlay and index methods where physical attributes are often mixed with implicitly embedded conventional priorities. Results from one or another of these last methods can consequently be very dissimilar for a given case study and decision makers are losing confidence in these tools. A methodology is proposed to reframe the groundwater vulnerability assessment in a Pressure-State-Impact causal chain that is familiar to decision makers. The DPSIR framework, for describing interactions between society and the environment, defines a chain of Drivers that exert Pressures on the State of a given resource, such as water, which then generates an Impact that will require an appropriate Response (Kristensen, 2004). The concept of groundwater vulnerability assessment considered here is based on the calculation of sensitivity coefficients for a user-defined groundwater state for which several physically-based indicators are proposed. These sensitivity coefficients reflect the easiness with which the groundwater state transmits pressures into impacts. They are grouped into a vulnerability matrix of pressures and impacts that quantify vulnerability for every combination of causal links identified in the DPSIR chain. For that reason, the sensitivity coefficients are converted to vulnerability, using the concept of ‘falling below a given threshold’, which is commonly used in socioeconomic sciences (Luers et al. 2003). Outside the careful selection of the sensitivity analysis method that can significantly influence the computational effort (Beaujean et al., 2013), emphasis will be given to the illustration of the general methodology on a simple case (of an alluvial aquifer with concerns related to water supply) demonstrating the potential use of this general and physically based vulnerability assessment method. While the methodology is general, the choice of causal chains has to be made prior to the calculation. The vulnerability is also related to a damaged state and is related to the ‘distance’ between the current state and a given threshold. This choice is arbitrary such that the vulnerability is sensitive to the choice of the threshold. The framework is general and, when applied to water, can include states that are not limited to quality such as, for example, water quantity and availability. [less ▲]
