In June 2014, the SFX® MISCELLANEOUS_FREE_EJOURNALS target contained more than 24,000 portfolios of all kinds. The SFX Knowledge Base Advisory Board (KBAB) decided to carry out an international survey to get an overview of the usage that is done of this target by the SFX community and to precisely identify what could be done to improve it. The target is widely used among the community. However, many respondents complained about these top three problems: (1) Incorrect parse params (broken links); (2) Full texts actually not free; (3) Incorrect or missing thresholds. [less ▲]

Faisant suite à une première phase (2006-2008), le projet pilote Développement d’Alternatives Communautaires à l’Exploitation Forestière Illégale (DACEFI-2, de 2010 à 2014) s’emploie à tester au Gabon la mise en oeuvre des premières forêts communautaires. Un de ses objectifs majeurs consiste à tester le concept de foresterie communautaire au sein de plusieurs sites partenaires et de témoigner de l’expérience acquise afin que le Ministère en charge des Forêts adapte le cadre réglementaire. Quatre textes majeurs régissent la foresterie communautaire au Gabon, une loi (n°16/01), un décret d’application (n°1028/PR/MEFEPEPEN) et deux arrêtés (n°018/MEF/SG/DGF/DFC et n°106/MEFEPRN). Ils encadrent le processus de création d’une forêt communautaire. Afin de les rendre accessibles à un plus grand nombre, le projet DACEFI-2 s’est proposé de développer plusieurs supports de vulgarisation à destination des agents des Eaux et Forêts et des villageois. En éditant et en diffusant une série de posters, de films ou encore de bandes dessinées, le projet a contribué à faire connaître dans les provinces de l’Ogooué-Ivindo et du Moyen-Ogooué, l’esprit de ces textes légaux qui visent à favoriser le développement des communautés locales. Ce document de capitalisation présente une compilation des outils développés par les équipes du projet pour mener à bien cette campagne de sensibilisation. Nous abordons la gestion forestière durable par le prisme de la foresterie communautaire en évoquant l’esprit de la loi et les enjeux de la foresterie sociale. Nous proposons également une série de recommandations, basées sur notre expérience au Gabon, afin d’optimiser l’efficacité des communautés engagées dans ce processus. [less ▲]

CoRoT and Kepler observations of red giant stars revealed very rich spectra of non-radial solar-like oscillations. Of particular interest was the detection of mixed modes that exhibit significant amplitude, both in the core and at the surface of the stars. It opens the possibility of probing the internal structure from their innermost layers up to their surface throughout their evolution on the red giant branch, as well as on the red clump. Our objective is primarily to provide physical insight into the mechanism responsible for mixed-mode amplitudes and lifetimes. Subsequently, we aim at understanding the evolution and structure of red-giant spectra along with their evolution. The study of energetic aspects of these oscillations is also important for predicting the mode parameters in the power spectrum. Non-adiabatic computations, including a time-dependent treatment of convection, are performed and provide the lifetimes of radial and non-radial mixed modes. We then combine these mode lifetimes and inertias with a stochastic excitation model that gives us their heights in the power spectra. For stars representative of CoRoT and Kepler observations, we show under which circumstances mixed modes have heights comparable to radial ones. We stress the importance of the radiative damping in determining the height of mixed modes. Finally, we derive an estimate for the height ratio between a g-type and a p-type mode. This can thus be used as a first estimate of the detectability of mixed modes. [less ▲]

Termites digestive tract and hindgut especially still holds many secrets despites hundreds of years of research. The complexity of the symbiotic microbial community and the contrast of physio-chemical environments found in lower termites paunch are potentially the key point to explain the efficiency of ligno-cellulose digestion. Contribution of advancing technologies accelerates the progress of our knowledge in this field. Here, we present multiple approaches combining old and recent techniques used to highlight the effect of ligno-cellulosic compounds on termite gut and the role of populations from the symbiotic microbial community. Termites Reticulitermes flavipes (Kollar) submitted to various artificial diets showed variations in flagellates populations profile and enzymatic activities. Differential protein expression was investigated using 2D-DIGE MALDI-TOF-TOF and 2D-LC-MS/MS using high resolution orbitrap analyzer. Results from both proteomic experiments tend to support each-other and bring complementary points of view. The gel-free analysis resulted in highly contrasted identification of enzymes involved in ligno-cellulose digestion and metabolism. Finally, differential feeding experiments leaded to in vivo selection of different symbiotic communities. These communities were characterized following some metabolism assays and allowed the cultivation of diverse microbial consortia using media closely related to the respective artificial diets. This work provides relevant data on termite and associated microbial community response to alimentary diets. [less ▲]

The numerical solution of high-frequency time-harmonic propagation problems by volumic discretization methods is a challenging task, most notably because of the very large size of the resulting linear systems. We present a framework for a class of iterative methods that distribute the work between several CPUs and exchange information between physical or artificial interfaces. The goal is to define subproblems of manageable sizes, and to exploit the power of parallel supercomputers. [less ▲]

On 14 June 2004, Benin ratified a new Code on Persons and Family – regulating, amongst other things, inheritance matters. Over the last couple of years, the number of inheritance cases handled by state courts has drastically increased in the capital city. How do people understand and use the law? While modern courts, like other public services, have been analyzed as part of everyday governance and the local state in West Africa, I on the other hand will focus on the ways in which the judiciary interprets and implements law. Within that context, hearings are a key moment of legal proceedings. How do litigants argue their cases? How do judges manage to settle inheritance quarrels? Using case studies of inheritance disputes and their litigation under the 2004 ‘Code on Persons and Family’, I try to understand how state laws are understood, utilized, and/or questioned in Cotonou.

Virus-like particles (VLPs) of human papillomavirus (HPV) are used as a vaccine against HPV-induced cancer, and recently we have shown that these VLPs are able to activate natural killer (NK) cells. Since NK cells collaborate with dendritic cells (DCs) to induce an immune response against viral infections and tumors, we studied the impact of this crosstalk in the context of HPV vaccination. NK cells in the presence of HPV-VLPs enhanced DC maturation as shown by an upregulation of CD86 and HLA-DR and an increased production of IL-12p70, but not of the immunosuppressive cytokine IL-10. This activation was bi-directional. Indeed, in the presence of HPV-VLPs, DCs further activated NK cells by inducing the upregulation of cell surface activation markers (CD69 and HLA-DR). The function of NK cells was also improved as shown by an increase in IFN-gamma secretion and cytotoxic activity against an HPV+ cell line. This crosstalk between NK cells and DCs needed CD40 interaction and IL-12p70 secretion, whereas NKG2D was not implicated. Our results provide insight into how VLPs interact with innate immune cells and how NK cells and DCs play a role in the immune response induced by this vaccine agent.

Ant mill, caterpillar circle, bat donut, bacteria vortex, duck swirl and fish torus are different names for rotating circular formations of animals, where individuals turn around a common centre. Even if the ubiquity of this behavioural phenomenon might have suggested common causes or fundamental underlying principles across contexts, a variety of proximate mechanisms can give rise to vortex behaviours. Here, we investigate if stigmergic process (mechanism of self-organisation wit hout direct communication or interaction between individuals) is able to produce different collective behaviours, notably collective vortices. We present an individual-based simulation model for the movement of populations in a resource landscape that allows us to vary the strength of the interactions mentioned above. The key assumption and novelty of our model is that individuals can cause the release of additional nutrients, as well as consuming them. Our model produces clear predictions. For example, we expect more tortuous individual movement paths and higher levels of aggregation in populations occupying homogeneous environments where individual movement makes more nutrients available. We also show how observed movement dynamics could change when local nutrient sources are depleted or when the population density increases. Our predictions are testable and qualitatively reproduce the different feeding behaviours observed in filter-feeding ducks (Anas clypeata), for example. We suggest that considering two-way interactions between feeding individuals and resource landscapes could help to explain fine-scale movement dynamics. [less ▲]

INTRODUCTION Toute société humaine construit son héritage collectif sur la transmission de valeurs et de rites permettant aux descendants de réguler leurs schèmes comportementaux, affectifs, sociaux et moraux sur base des repères culturels alloués depuis des décennies. Investiguer les balises culturelles et l’appréhension sociétale du néoplasme pédiatrique reste peu développé dans la littérature. Ce champ « anthropo-clinique » prend initialement son essor dans la clinique oncologique adulte où des résultats significatifs montrent un lien entre la culture et la perception du cancer. OBJECTIFS Les objectifs de cette étude sont multiples: (a) étudier l’effet de la culture dans la représentation de la maladie cancéreuse de l’enfant, (b) analyser transculturellement les similitudes et les dissimilitudes entre la culture japonaise et occidentale, et (c) mettre en exergue les diverses implications cliniques pour les professionnels de la santé. METHODE Une revue de littérature est conduite afin de dégager les tendances culturelles dans la politique sanitaire, le service hospitalier, la relation médecin-malade, le concept de douleur, l’environnement familial et la perception de la mort au Japon et en Occident. Le choix s’est porté sur ce pays asiatique par la présence de certains repères culturels intéressants dans le domaine de l’oncologie pédiatrique. RESULTATS (a) Etudier l’effet de la culture dans la représentation de la maladie cancéreuse de l’enfant Les correspondances effectuées ont permis d’entrevoir la situation onco-pédiatrique comme relevant de faits biologiques et de faits culturels. Les paramètres culturels interviennent au sein des nombreuses conceptions et représentations sociales de la maladie cancéreuse d’un enfant. L’ensemble de ces perceptions sociales étant notamment influencées par les valeurs et les truismes véhiculés dans la culture. (b) Analyser transculturellement les similitudes et les dissimilitudes entre la culture japonaise et occidentale. Eléments de similitudes : Il a été noté l’universalité des mécanismes pathogéniques du cancer chez l’enfant et le développement de politiques sanitaires dans la lutte contre le cancer. Eléments de dissimilitudes : A. Le Japon Le système familial japonais et son organisation des soins en cancérologie de l’enfant varient et se teintent de nombreuses coutumes shintoïstes et bouddhistes. Il a été identifié le chaos régnant dans ses familles où des attitudes désengagées existent. L’organisation hospitalière japonaise est décrite comme carencée en réseaux de soutien psychologique pour la mère, très souvent seule face à la maladie de son enfant. Des risques majeurs de dépression, de traits anxieux et d’un stress post-traumatique sont observés. Le médecin japonais dispose d’un pouvoir de décision médicale et sociale, se manifestant notamment par un degré de variabilité dans la communication diagnostique et pronostique envers la famille et l’école d’origine. La situation de soin est variable avec l’inclusion en premier lieu d’une pharmacopée naturelle afin de traiter le cancer et ses effets iatrogènes. Enfin, il subsiste une inhibition du partage social des émotions où, des attitudes de retenue et de silence chez les parents se manifestent durant tout le processus thérapeutique mais aussi en cas de décès de l’enfant. B. L’Occident Les pays occidentaux présentent une appréhension sociale et médicale singulière du cancer pédiatrique. La variabilité observée concerne l’organisation hospitalière et la communication médicale. Le praticien occidental établit une communication médicale ouverte avec l’enfant et sa famille et ce, dès le départ du processus thérapeutique. Le contexte curatif est caractérisé par une forte médication d’opioïdes afin de pallier aux nombreuses douleurs et effets des traitements. L’aménagement hospitalier permet la création de réseaux de soutien psychologique pour l’enfant et sa famille et l’établissement d’activités ludiques.(c) Mettre en exergue les diverses implications cliniques pour les professionnels de la santé L’intention de cette étude est de sensibiliser les professionnels de la santé à la pléiade de facteurs psycho-sociaux intervenant dans un contexte de maladie néoplasique. Éléments qui doivent requérir d’une bienveillance clinique où tant l’enfant traité que son entourage familial, doivent être entendus dans toute leur spécificité d’être humain. DISCUSSION Une stratégie d’action intéressante concernerait une grille de lecture culturelle du patient et de sa famille. Cette grille peut offrir un entendement de la diversité culturelle en psycho-oncologie et peut permettre au professionnel de réajuster finement son travail clinique dans un contexte quotidien de multiculturalité. Cette grille de lecture doit rester simple et proposer un petit nombre de « repères culturels » (items culturels) pour professionnels, leurs permettant d’ajuster certains paramètres cliniques (communication médicale, gestion des émotions, rapport à la mort, etc.). Cette considération ethnologique du patient doit supposer au préalable une formation de compétences dans le domaine de la culture et de la santé/maladie. [less ▲]

In order to operate an electrical distribution network in a secure and cost-efficient way, it is necessary, due to the rise of renewable energy-based distributed generation, to develop Active Network Management (ANM) strategies. These strategies rely on short-term policies that control the power injected by generators and/or taken of by loads in order to avoid congestion or voltage problems. While simple ANM strategies would curtail the production of generators, more advanced ones would move the consumption of loads to relevant time periods to maximize the potential of renewable energy sources. However, such advanced strategies imply solving large-scale optimal sequential decision-making problems under uncertainty, something that is understandably complicated. In order to promote the development of computational techniques for active network management, we detail a generic procedure for formulating ANM decision problems as Markov decision processes. We also specify it to a 75-bus distribution network. The resulting test instance is available at http://www.montefiore.ulg.ac.be/~anm/ . It can be used as a test bed for comparing existing computational techniques, as well as for developing new ones. A solution technique that consists in an approximate multistage program is also illustrated on the test instance. [less ▲]

In this paper I look at the particular situation of Congolese and Belgian-Congolese citizens in Belgium, the former colonial metropole. From research conducted over ten years within Congolese circles I argue that postcolonial immigrants/citizens have for the last three decades been experiencing a significant social malus. Not only does daily racial discrimination inform and supply it but so also does treatment by the state itself through its various institutions. Looking at some data collected from political, associative and artistic spheres I argue that the Congolese in Belgium have to deal with a postcolonial malus. My research is grounded on a comprehensive anthropology which privileges the actors’ own perspective. I thereby explore the elements, trends or configurations of the post-migratory situation which may be considered inherited from colonialism. Finally, I discuss the reason why despite three decades of “postcolonial activism”, the postcolonial critique is not a live social issue in French-speaking Belgium. [less ▲]
