This paper highlights technical and economic choices for rural electrification in Africa and presents the rationale for trigeneration in health and education applications. An archetypal load profile for a rural health clinic (25 kWh/day 118-139 kWht ) is described and a regional analysis is performed for sub Saharan Africa by aggregating NASA meteorological data for e.g. insolation, temperature, and heating and cooling degree days using correlates to latitude. As a baseline for comparison, the technical, economic (using discounted cash flow) and environmental aspects of traditional electrification approaches, Photovoltaic (PV) systems and diesel generators, are quantified and options for meeting heating and cooling loads (e.g. gas-fired heaters, absorption chillers, or solar water heaters) are evaluated alongside an emerging micro-scale Concentrating Solar Power (CSP) technology featuring a solar thermal Organic Rankine Cycle (ORC). Photovoltaics hybridized with LPG/Propane and μ-CSP trigeneration are the lowest cost alternatives for satisfying important but often overlooked thermal requirements, with cost advantages for μ-CSP depending on latitudinal variation in insolation and thermal parameters. For a 15-year project lifetime the net present cost for meeting clinic energy needs varied from 44-55k USD, with specific levelized electricity costs of 0.26-0.31 USD/kWh. Diesel generation is both costly and polluting (94 tons CO2 per site over 15 years), while LPG/Propane based heating and cooling results in 160-400 tons CO2 emittted. The comparative analysis of available technologies implies that where the energy demand includes a mixture of electrical and thermal loads, as in typical health and education outposts, μ-CSP trigeneration approaches are cost effective and a non-carbon emitting.

La thèse analyse les politiques et les interventions en matière de protection de l'enfance au Burkina Faso. Les enseignements de cette recherche concernent sa dimension empirique d'une part et son objet spécifique d'autre part. Cet objet n'est pas le travail des enfants comme tel, mais la construction d'une politique publique dans un pays qui reste massivement rural et largement dépendant de l'aide internationale. [less ▲]

The concept of Community of Practice (CoP) takes nowadays a great part in the formal or informal learning domain. In addition, computerised tools are often used to sustain the activities of these communities (Wenger, White & Smith, 2009). The ÉduCoP case study deals with the creation and the animation process of a CoP that was launched in 2010 at the University of Liège. Initiated by a master student in educational sciences, it aims at developing and making durable a community of practice composed of learners in this field and supported by Information and Communication Technologies. This paper presents several actions undertaken to develop this CoP: the analysis of the potential members' needs, stakes and motivations of students to enrol in this project; the choice of useful and usable technological tools to provide them (here, the eGroupWare platform) and the training sessions linked to its efficient uses; the activities conducted to develop the CoP's members identity and to lead them to debate about common topics, to produce and share resources. The CoP's evolution was observed through qualitative and quantitative data collection processes (e.g. interviews about the members' implication and roles, support from animator, obstacles, feeling to belong to a CoP, analysis of the topics presented in the posted documents and messages, uses of the technological tools, frequency of connection...). The results are discussed here and perspectives are evoked for this CoP. If the actions undertaken show encouraging results, neverthless obstacles to the creation and the evolution of such a CoP have been identified (e.g. lack of technological culture among some members, reluctance to share personal productions). Some perspectives are considered to overcome these problems. Since October 2011, this initiative has been recognised at the institutional level: the university is interested in lessons learned in order to implement CoP into other faculties that would be willing to start networking and create communities of learners or of practice.

Uncertainty quantification of multiphysics systems represents numerous mathematical and computational challenges. Indeed, uncertainties that arise in each physics in a fully coupled system must be captured throughout the whole system, the so-called curse of dimensionality. We present techniques for mitigating the curse of dimensionality in network-coupled multiphysics systems by using the structure of the network to transform uncertainty representations as they pass between components. Examples from the simulation of nuclear power plants will be discussed. [less ▲]

We present a computational framework based on stochastic expansion methods for the efficient propagation of uncertainties through multiphysics models. The framework leverages an adaptation of the Karhunen-Loeve decomposition to extract a low-dimensional representation of information passed from component to component in a stochastic coupled model. After a measure transformation, the reduced-dimensional interface thus created enables a more efficient solution in a reduced-dimensional space. We demonstrate the proposed approach on an illustration problem from nuclear engineering [less ▲]

In contrast to general expectations the growth of EU membership as well as European treaty reform has not had any significant impact on the Council’s overall legislative and roll call activity. On the basis of a new dataset representing the total population of public roll calls and recorded votes in the Council this paper explains why the EU Council has been so successful in guaranteeing legislative and roll call stability between 1995 and 2010. The quantitative and qualitative analysis finds that frontloading legislation, changing voting behaviour, reinforcement of existing coalition patterns and the successful adjustment of newer Member States to the EU Council have contributed to the EU Council’s decision-making capacity during the observed 16 years. In explaining the apparent contradiction between institutional change and the Council’s legislative stability this paper contributes to our knowledge of the functioning, the decision-making processes and the geography of contestation in the EU Council.
