[more ▼] The European Landscape Convention acknowledges landscape as a key element in territorial development, management and planning (assessment of the effects of certain public and private projects on the environment, re-landscaping, landscape projects design, charters…). Based on a doctoral research investigating the processes of landscape project design on a local scale in Wallonia (Belgium) in Nature Parks, Local Action Groups or River Contracts, the paper tries to analyze how landscape influences territorial practices and issues. It aims also to produce an evaluation on how landscape action transforms territorial governance and decision-making process. In doing so, the paper relates landscape project contributions and limits assuming new landscape management challenges. And finally, it reframes the contribution of the landscape issue to regional and local development.

[more ▼] Les processus de gestion de la qualité sont relativement récents dans l'enseignement universitaire en Belgique francophone. Sous la pression européenne, avec le soutien des responsables des universités, les autorités ont mis en places des dispositifs d''évaluation tout à fait nouveaux. Après quelques années de rodage, ces instruments semblent se stabiliser, bien qu'ils continuent encore à susciter çà et là des réactions de rejet. Pour mieux comprendre ces dynamiques, c'est par la base qu'il convient de démarrer l'analyse, pour suivre au plus près les instruments d'évaluation, leur mode d'emploi et comprendre leurs effets inattendus au sein des universités, mais pour observer l'émergence de nouveaux modes de coordination entre universités, avec l'administration, ou avec les autres acteurs sociaux. Ce chapitre présente en détail le processus d'évaluation, après un bref rappel de ses origines et du contexte qui a favorisé son émergence. Ensuite, il proposera un analyse transversale de cet instrument d'action publique : en quoi les nouvelles formes de coopération qui se mettent en place sont emblématiques à la fois d'un nouveau rapport entre gouvernants et gouvernés mais aussi entre les universités et la société qui les nourrit tout en lui fiant leurs enfants.

[more ▼] Gammaherpesviruses are the archetypes of persistent viruses that have been identified in a range of animals from mice to man. As the human gammaviruses have no well-established in vivo infection model, related animal gammaherpesviruses are an important source of information. We are studying Murid herpesvirus 4 (MuHV-4) in inbred laboratory mouse strains which are commonly accepted as a good model for studying gammaherpesviruses in vivo. To date, it has however never been possible to monitor viral reexcretion and virus transmission in this species. In order to identify potential re-excretion sites, intranasally infected mice were followed through global luciferase imaging for up to six months after infection. Surprisingly, we detected transient viral replication in mice genital tract at various times after latency establishment. Ex vivo imaging, quantitative PCR and immunohistochemistry revealed that virus genomes were present in high quantity in the vaginal tissue and that viral replication occurred mainly at the vaginal external border. Moreover, we highlighted the presence of free infectious viruses in the vaginal cavity at the moment of the observation of viral replication. As this ephemeral viral reexcretion could reveal a link with reproductive cycle, we compared reexcretion in normal and ovariectomized mice. Interestingly, no viral reactivation was observed in absence of hormonal cycle. In conclusion, we experimentally indentified for the first time a reexcretion site for MuHV-4 in mice that had been intranasaly infected. In the future, these results could help us to better understand the biology of gammaherpesviruses but should also allow us to develop strategies that could prevent the spread of these viruses in natural populations.

[more ▼] The term « Pet bird » designates birds housed and breeded for an exclusively ornamental use. This category includes mainly Passeriformes (canaries, finches…) and Psittaciformes (parrots, parakeets…), and is a not-so-well known vet’s clientship fraction. Many families indeed own their « kitchen canary », which represent a lucrative business for pet shops or local breeders (e.a. via birds fairs and markets). Besides, some birds are bred for their very high value; for example, in the case of canaries, male and female reproductors with recognized genetic potential are presented in international contests for their posture (the Bossu Belge : fig 1a), their colour (red mosaic: fig 1b) and for their song (Harzer: fig 1c) and sold for rising prices. Finally, exotic birds like parrots (ara, cockatoo…), legally or illegaly traded from Asia, are however very popular pets and profusely represented in zoos and parks. Notwithstanding these economic facts, these animals are potential carriers and/or transmitters of zoonotic diseases. Some of them could have an important impact on human health, like ornithosis, salmonellosis or even H5N1 high pathogenic avian influenza. This review, although non exhausive, has as aim to enlighten, by the description of several cases of birds-humans transmission the risks encountered by birds owners, including children, and on another point of view to assess the potential economic consequences.

[more ▼] Le but de cette étude a été d’évaluer la conservabilité de viandes bovines de différentes origines (Royaume-Uni et Irlande, Australie et Brésil) et l’influence sur celle-ci de la température de conservation (1 °C vs. +4 °C). Des paramètres physico-chimiques (pH, couleur, proportion des différentes formes redox de la myoglobine (FRMb), indice TBARS et acides organiques) et microbiologiques (flore aérobie totale, flore lactique, Enterobacteriaceae, Pseudomonas spp. et Brochothrix thermosphacta) ont été mesurés sur sept lots de contre-filet conditionnés sous vide : aux ⅔ de la DLC et à la fin de la DLC. La diversité bactérienne a été évaluée par galeries API50 CHL et par métagénomique. Le pH a diminué au cours de la conservation dans deux lots. La couleur et la proportion des FRMb sont restées stables. Une augmentation de l’indice TBARS, plus prononcée à +4 °C, a été observée. Les viandes australiennes et brésilienne ont présenté des taux en acides acétique et citrique plus élevés. Tous les lots conservés à 1 °C ont présenté une qualité microbiologique satisfaisante à la fin de leur DLC (viandes britanniques et irlandaises = 35 ~ 45 jours; australiennes = 140 jours et brésilienne = 120 jours). La conservation à +4 °C a favorisé la croissance d’entérobactéries, facteur limitant de la conservation de plusieurs lots. L’identification bactérienne a révélé la présence de bactéries connues pour leur effet bioprotecteur. La phase ultérieure de ce travail consistera à étudier la dynamique de la flore microbienne endogène en fonction des conditions environnementales appliquées (température, atmosphère).

[more ▼] In large-scale networks, full-mesh active probing of end-to-end performance metrics is infeasible. Measuring a small set of pairs and predicting the others is more scalable. Under this framework, we formulate the prediction problem as matrix completion, whereby unknown entries of an incomplete matrix of pairwise measurements are to be predicted. This problem can be solved by matrix factorization because performance matrices have a low rank, thanks to the correlations among measurements. Moreover, its resolution can be fully decentralized without actually building matrices nor relying on special landmarks or central servers. In this paper we demonstrate that this approach is also applicable when the performance values are not measured exactly, but are only known to belong to one among some predefined performance classes, such as "good" and "bad". Such classification-based formulation not only fulfills the requirements of many Internet applications but also reduces the measurement cost and enables a unified treatment of various performance metrics. We propose a decentralized approach based on Stochastic Gradient Descent to solve this class-based matrix completion problem. Experiments on various datasets, relative to two kinds of metrics, show the accuracy of the approach, its robustness against erroneous measurements and its usability on peer selection.
