In this article, we evaluate, from the point of view of banks, the potential of articulations between commercial banks and microfinance institutions (MFIs) in Cameroun in terms of financing of the rural and the micro, small and medium enterprises (MSMEs). Furthermore, we seek to define the best form of partnership between the two types of institutions. The results obtained suggest that the articulations between banks and MFIs can potentially be beneficial to all stakeholders (banks, MFIs but also recipients). This study also highlights the fact that these articulations can be even more beneficial if national commercial banks, under the Cameroonian law in our case, participate rather than branches of foreign banking groups. Indeed, our research reveals that through these partnerships, from their cultural proximity and their propensity to take more risks, national commercial banks will more likely offer either directly or indirectly (through MFIs) more adapted financial products and services to both the rural and the MSMEs’ segments. The question of knowing if a better form of partnership between commercial banks and MFIs exists, results suggest that there is no better form of partnership as such; that the best form depends on the MFI’s development stage and that in any case this partnership should privilege a national commercial bank rather than a branch of a foreign bank. Even if the foreign banks’ contest might be necessary at a given stage of the process, the results make it also possible to consider a new model of interactions implying Microfinance investment vehicles and national commercial banks. This model would have the advantage to help mitigate risks that those vehicles perceive when deciding to directly invest in MFIs. [less ▲]

For five years, a postgraduate program in Educational and Training Technology has been developed by both Universities of Liège and Namur (Belgium). This program addresses already graduated adults having a training background. Depending on his/her training experience and a personnal project, the participant has the opportunity of developing different competencies profiles like: educational designer, designer and manager of training systems integrating ICT, e-tutor or trainer in e-learning environments, designer and producer of information or learning multimedia products. The plan of action articulates face-to-face and distance activities. It is based on several principles like definition and follow-up of a personal learning project, clarification of the actors’ roles, systematical use of technologies, active pedagogical methods and quality process. The authors present a series of scenarios including several types of distance activities. On the one hand, they illustrate these activities, insisting on their target goals, their meaning and usefulness, their development and their evaluation criteria. On the other hand, they discuss the organization of face-toface, blended or distance activities taking into account different sides of a learning system in order to stimulate the thought of designers and animators of such learning environments.

Une maison explose en plein coeur de la ville de Liège, piégeant plusieurs victimes sous les décombres... C'est le déclenchement de nombreuses actions menées dans l'urgence par des professionnels du risque et de la gestion de crise. Partant de l'analyse de cet événement et de ses enseignements, cet ouvrage, fruit de rencontres entre chercheurs et professionnels, tente d'articuler risques, planification d'urgence et gestion de crise. La diversité des phénomènes auxquels nos sociétés sont confrontées est grande et l'organisation de l'action publique dans ce domaine nécessite la coordination d'acteurs et d'institutions aux compétences et horizons différents. Cet ouvrage a pour ambition de décortiquer cette réalité en l'éclairant ici avec des considérations théoriques et là avec des exemples concrets issus de l'expérience de terrain. [less ▲]

Que se passe-t-il lorsqu'un romancier tourne le fait divers en récit ? Réfléchir sur ce sujet signifie élargir la notion de « narratologie restreinte », pour adopter une terminologie à la Genette, centrée essentiellement sur la fiction en vertu de l'idée de roman comme genre narratif privilégié. Or ce privilège apparaît désormais suranné, d'autant plus que l'hybridation des formes narratives (fiction et non-fiction) et la mobilité des frontières (littérature et cinéma) rendent problématique l'inscription dans un statut défini. À priori, la transposition littéraire d'un fait divers n'est pas esthétiquement inférieure à un ouvrage inventé de toutes pièces. Les artifices de la non-fiction, dans les expressions les plus réussies, restituent une forme d'(in)crédibilité à la fiction, l'exposent aux interférences ordinaires du hasard, de même que les stratégies de la fiction authentifient le journal intime, le fait divers et le reportage, leur conférant ce gradient de vérité que la simple information ne possède pas. À l'époque de la simulation et de l'agonie des référentiels forts, « ce n'est plus le roman qui est en quête d'authenticité, c'est l'authenticité qui est en quête de fiction » (M. Laouyen). [less ▲]

We analyze the influence of dipole-dipole interactions between Rydberg atoms on the generation of Abelian artificial gauge potentials and fields. When two Rydberg atoms are driven by a uniform laser field, we show that the combined atom-atom and atom-field interactions give rise to nonuniform, artificial gauge potentials. We identify the mechanism responsible for the emergence of these gauge potentials. Analytical expressions for the latter indicate that the strongest artificial magnetic fields are reached in the regime intermediate between the dipole blockade regime and the regime in which the atoms are sufficiently far apart such that atom-light interaction dominates over atom-atom interactions. We discuss the differences and similarities of artificial gauge fields originating from resonant dipole-dipole and van der Waals interactions. We also give an estimation of experimentally attainable artificial magnetic fields resulting from this mechanism and we discuss their detection through the deflection of the atomic motion. [less ▲]

For now over a decade, real-time strategy (RTS) games have been challenging intelligence, human and artificial (AI) alike, as one of the top genre in terms of overall complexity. RTS is a prime example problem featuring multiple interacting imperfect decision makers. Elaborate dynamics, partial observability, as well as a rapidly diverging action space render rational decision making somehow elusive. Humans deal with the complexity using several abstraction layers, taking decisions on different abstract levels. Current agents, on the other hand, remain largely scripted and exhibit static behavior, leaving them extremely vulnerable to flaw abuse and no match against human players. In this paper, we propose to mimic the abstraction mechanisms used by human players for designing AI for RTS games. A non-learning agent for StarCraft showing promising performance is proposed, and several research directions towards the integration of learning mechanisms are discussed at the end of the paper.

A framework is proposed to tackle the online transient stability problem of power systems. Based on artificial intelligence, it successively makes use of an inductive inference method to build decisions automatically and a deductive inference method to apply them online. The authors lay the foundations of an inductive inference method, where the rules explicitly relate a system's stability with relevant parameters of it. A simple but realistic power system is treated to illustrate important features of the method and to suggest how the derived decision rules could be used online. [less ▲]

Knowing the metabolic balance of an ecosystem is of utmost importance in determining whether the system is a net source or net sink of carbon dioxide to the atmosphere. However, obtaining these estimates often demands significant amounts of time and manpower. Here we present a simplified way to obtain an estimation of ecosystem metabolism. We used artificial neural networks (ANNs) to develop a mathematical model of the gross primary production to community respiration ratio (GPP:CR) based on input variables derived from three widely contrasting European coastal ecosystems (Scheldt Estuary, Randers Fjord, and Bay of Palma). Although very large gradients of nutrient concentration, light penetration, and organic-matter concentration exist across the sites, the factors that best predict the GPP:CR ratio are sampling depth, dissolved organic carbon (DOC) concentration, and temperature. We propose that, at least in coastal ecosystems, metabolic balance can be predicted relatively easily from these three predictive factors. An important conclusion of this work is that ANNs can provide a robust tool for the determination of ecosystem metabolism in coastal ecosystems. [less ▲]
