Faecal carriage of Clostridium difficile in healthy animals has been reported recently, especially in piglets and calves. However there is limited data about carriage in animals just prior to slaughter in Europe. The main objective of this study was to determine the presence of C. difficile in pigs and cattle at the slaughterhouse. C. difficile was isolated in 6.9% of the cattle at the slaughterhouse. None of the pig slaughter samples were positive for C. difficile after an enrichment time of 72 h. For complementary data, a short study was conducted in piglets and calves at farms. C. difficile was more prevalent in piglets (78.3%) than in calves (22.2%) on the farms. Regarding the piglet samples, 27.8% of the positive samples were detected without enrichment of stools. The PCR ribotype 078 was predominant in farm animals. Samples isolated from slaughter cattle presented the widest range in PCR-ribotype variety, and the most prevalent PCR ribotype was 118a UCL. The results of this study confirm that C. difficile is present in slaughter animals in Belgium with a large percentage of toxigenic strains also commonly found in humans. [less ▲]

Pendant la petite enfance, les grands prématurés restent fragiles. Une étude récente (de Kieviet et al, 2009) met en évidence un retard psychomoteur de cette population par rapport à la normale. A partir de 3 ans, de nombreuses activités existent pour stimuler leur développement moteur mais avant cet âge, rien n’est organisé. Nous avons donc décidé de mettre sur pied une activité de psychomotricité adaptée à cette population, entre 1,5 et 3 ans. L’objectif de cette étude consistait à valider cette activité de développement originale. Appliquant les principes des recherches-action, nous avons structuré notre démarche en quatre phases : (1) la planification durant laquelle nous avons mené une réflexion sur l’organisation et le contenu de l’activité ; (2) l’intervention au cours de laquelle fut expérimentée l’activité et fut collectée une série d’informations ; (3) l’analyse des données et ; (4) l’aménagement d’un nouveau modèle tenant compte des étapes précédentes. La validation menée lors de l’intervention repose sur la triangulation des données : interview et questionnaires proposés aux parents, questionnaire adressé aux moniteurs et interviews semi-structurées réalisées auprès de 10 experts de la psychomotricité et/ou des prématurés (pédiatres, kinésithérapeutes, logopèdes, psychologues, psychomotriciens). Une analyse de contenu a été réalisée afin de dégager les éléments de sens qui ont été compilés. Les différents acteurs s’accordent sur la majorité des éléments proposés dans les activités (contenu, matériel, espaces, diversité) et sur l’organisation (structuration, jeux libre, binôme kinésithérapeute-éducateur sportif). Des ajustements paraissent nécessaires au niveau de la phase d’accueil et du rituel de fin de séance. La présence des parents durant l’activité fait débat. Le projet a été initialement bien pensé et la majorité du concept a été validée par les experts. De légères adaptations ont été programmées. Cette étude renforce la crédibilité de l’initiative dont l’intérêt a été chaleureusement salué par les parents. [less ▲]

Le dialogue intérieur est constitué de pensées qui sont généralement spontanées mais qui peuvent également être sous le contrôle direct du sportif. Selon Hatzigeorgiadis, Zourbanos, Galanis et Theodorakis (2011), le discours peut revêtir une orientation pédagogique ou motivante. Ces auteurs ont montré que les pensées motivantes sont plus efficaces pour améliorer la performance dans des situations nécessitant un effort de longue durée ou de la force. Par contre, le discours pédagogique est plus utile pour les tâches qui demandent du temps et/ou de la précision. Les pensées spontanées des sportifs sont à 80% négatives. Il est donc logique de tenter de modifier cette situation afin d’augmenter la part des pensées opérationnelles (objectif clair, énoncé bref et simple phonétiquement, initiation d’un acte ou un geste concret, stimulation). Dans cette étude, nous testons une approche visant justement à amener des sportifs à mieux exploiter leur dialogue intérieur. Notre étude porte sur 5 joueuses de volley-ball de 2ème nationale belge (postes de jeu différents) provenant de deux équipes, toutes volontaires. Nous avons filmé une première confrontation entre ces deux formations. Sur base de l’enregistrement vidéo, nous avons effectué des entretiens stimulés individuels ciblant divers événements survenus lors de la rencontre. Ces retours sur la pratique nous ont permis d’identifier les pensées des joueuses. Par la suite, chacune de celles-ci a participé à deux séminaires individuels qui avaient pour objectif de modifier les pensées négatives et positives en pensées opérationnelles. A l’issue du match retour, nous avons répété une séance de rappel stimulé et avons complété la collecte des données par un débriefing général. Parmi les résultats que nous avons déjà mis en évidence, nous retiendrons que le discours pédagogique s’avère particulièrement pauvre par rapport au discours motivant. Des implications pratiques sont proposées. [less ▲]

Over the past decades, video games have become increasingly popular and complex. Virtual worlds have gone a long way since the first arcades and so have the artificial intelligence (AI) techniques used to control agents in these growing environments. Tasks such as world exploration, con- strained pathfinding or team tactics and coordination just to name a few are now default requirements for contemporary video games. However, despite its recent advances, video game AI still lacks the ability to learn. In this paper, we attempt to break the barrier between video game AI and machine learning and propose a generic method allowing real-time strategy (RTS) agents to learn production strategies from a set of recorded games using supervised learning. We test this imitative learning approach on the popular RTS title StarCraft II® and successfully teach a Terran agent facing a Protoss opponent new production strategies. [less ▲]

This book presents and analyzes the results of a comprehensive collection of data on the extent and condition of transport infrastructure in Sub-Saharan Africa, identifies the reasons for poor performance, and estimates future financing needs. The transport facilities of Sub-Saharan Africa were built primarily for the colonial exploitation of mineral and agricultural resources. The chief goal of road and rail networks was to link mines, plantations, and other sites for the exploitation and transformation on natural resources to ports, rather than to provide general connectivity within the region. The road network of 1.75 million kilometers exhibits a low density with respect to population. Its average spatial density is very low by world standards. The network carries low average traffic levels. Even so, because most African countries have a low GDP, the fiscal burden of the network is the highest among world regions, maintenance is underfinanced, and road conditions are on average poor, while road accident rates are very high. Attempts to improve the financing of maintenance through “second generation road funds” have met with some success, but there remain serious weaknesses in implementation. Road freight transport is fragmented, but cartelized, with high rates and high profits. Railways were also built mainly as for the exportation of minerals and crops. With the exception of two or three very specialized bulk mineral lines, the traffic volumes are low, and the railways have been in financial decline since the 1960s. Concessioning of the lines to private operators has improved performance, but governments often impose unachievable requirements on the companies, and investment remains inadequate for long-term sustainability. Most of the 260 airports that provide year-round commercial service in Sub-Saharan Africa have adequate runway capacity, though some of the larger airports suffer from a shortage of terminal capacity. More than a quarter of the runways are in marginal or poor condition, and air traffic control and navigation facilities are below international standards. Though airport charges are high, few airports are truly financially sustainable. Three national carriers are quite successful, but most are small and barely sustainable. Protection persists in the domestic and intercontinental markets, but the international market in the region has been effectively liberalized. The safety record is poor. Most ports are small by international standards. Many are still publicly owned and suffer from inadequate equipment and poor productivity. Only a few highly specialized ports, including private ports integrated with the extraction companies, meet the highest international standards Costs and charges are high. But there is a trend toward concessioning of facilities to large groups specializing in international container terminals and port operations. Fortunately the shipping market is now deregulated. Urban transport suffers from some infrastructure deficiencies, particularly in the condition of urban roads. But the main problems of the sector are associated with the fragmented and poorly regulated nature of most urban bus markets. Finance for large buses is very difficult to obtain. In all modes the situation is made worse by failures of governance in both the provision and regulation of infrastructure. The overall deficit in financing for infrastructure is estimated using a model based on the application of hypothesized standards of connectivity for all modal networks and facilities. Once the amount of infrastructure needed to meet those standards was calculated, these “requirements” were compared with existing stocks and the costs of making the transition over a ten-year period were calculated. A “base” scenario used standards similar to those pertaining in developed regions, while a “pragmatic” scenario applied lower standards. In a separate exercise, the actual average expenditures on transport infrastructure from all sources were researched. This allowed the funding gap to be deduced by subtraction. The results showed that, excluding official development assistance, no country spent enough to meet the base standard, and that even with aid there remained substantial deficits in maintenance funding in many countries, with the worst situations found in the low-income, politically fragile group of countries.

The present study was carried out on 19 stress negative Piétrain pigs (Pietrain ReHal), consisting of 13 gilts and 6 young boars imported from Belgium, raised in the livestock farm of Dong Hiep (Hai Phong) in order to evaluate growth performances and their adaptability in the North of Vietnam. Results showed that the average body weight of the whole herd at 2, 4, 5.5, and 8.5 months old was 19.05, 51.05, 85.82, and 119.47 kg, respectively. During the growing periods, except the first stage, the male grew faster than the female and the pigs of the CT genotype grew faster than those of CC genotype although the difference was not significant (P>0.05). The average daily gain (ADG) was 528.56 grams for the whole herd. The ADG was higher for the male (546.48 grams) than for the female (520.29 grams), and its was higher for the CT than the CC, but the difference was not statistically significant (P>0.05). The feed conversion ratio (FCR) was 2.69 kg. The estimated lean percentage at 8.5 months old was 64.08%. The results indicate that Piétrain stress negative pigs could develop well on the farm conditions in Hai Phong, Vietnam. [less ▲]

This paper focuses on the assessment of the economic performance of seven African railway enterprises using a Total Factor Productivity index decomposition. This method shows the role of these public enterprises in the production and distribution of added value. The analysis allows to identify the, positive or negative, contribution of each production factor to productivity growth. At the same time, it shows how the firm's partners do, or do not benefit from the added value created by these companies. [less ▲]
