Energy policies for rural electrification: a social multi-criteria evaluation approach

In this article, a real-world case- study is presented with two general objectives: to give a clear and simple illustrative example of application of social multi-criteria evaluation (SMCE) in the field of rural renewable energy policies, and to help in understanding to what extent and under which circumstances solar energy is suitable for electrifying isolated farmhouses. In this sense, this study might offer public decision- makers some insight on the conditions that favour the diffusion of renewable energy, in order to help them to design more effective energy policies for rural communities.

Social Multi-Criteria Evaluation (SMCE)

The main argument developed here is the proposal of the concept of “Social Multi-Criteria Evaluation” (SMCE) as a possible useful framework for the application of social choice to the difficult policy problems of our Millennium, where, as stated by Funtowicz and Ravetz, “facts are uncertain, values in dispute, stakes high and decisions urgent”. This paper starts from the following main questions: 1. Why “Social” Multi-criteria Evaluation? 2. How such an approach should be developed? The foundations of SMCE are set up by referring to concepts coming from complex system theory and philosophy, such as reflexive complexity, post-normal science and incommensurability. To give some operational guidelines on the application of SMCE basic questions to be answered are: 1. How is it possible to deal with technical incommensurability? 2. How can we deal with the issue of social incommensurability? To answer these questions, by using theoretical considerations and lessons learned from realworld case studies, is the main objective of the present article.

Indicators and evaluation tools for the assessment of urban sustainability

This paper attempts to provide an explanation of why reductionistic approaches are not adequate to tackle the urban sustainability issue in a consistent way. Concepts such as urban environmental carrying capacity and ecological footprint are discussed. Multicriteria evaluation is proposed as a general multidimensional framework for the assessment of urban sustainability. This paper deals with the following main topics: 1) definition of the concept of urban sustainability 2) discussion of relevant sustainability indicators 3) multicriteria evaluation as a framework for the assessment of urban sustainability 4) an illustrative example.

The Spanish cadet in the European military context a comparative analysis of the professional socialisation

Research on the attitudes, motivations and social and political behavior of European cadets have been made throughout the last decade. Nowadays Spain also joins those surveys. Thru the analysis of polling data, we can consider the different attitudes of Spanish cadets in relation with the other European ones. The conclusion is that although the Spanish political transition to democracy has not ended already in the military teaching system, there are a lot of similarities among Spanish and European cadets.

Contractive metrics for a Boltzmann equation for granular gases: diffusive equilibriaThe Patterson-Sullivan embedding and minimal volume entropy for outer space

We quantify the long-time behavior of a system of (partially) inelastic particles in a stochastic thermostat by means of the contractivity of a suitable metric in the set of probability measures. Existence, uniqueness, boundedness of moments and regularity of a steady state are derived from this basic property. The solutions of the kinetic model are proved to converge exponentially as t→ ∞ to this diffusive equilibrium in this distance metrizing the weak convergence of measures. Then, we prove a uniform bound in time on Sobolev norms of the solution, provided the initial data has a finite norm in the corresponding Sobolev space. These results are then combined, using interpolation inequalities, to obtain exponential convergence to the diffusive equilibrium in the strong L¹-norm, as well as various Sobolev norms.

Contractive probability metrics and asymptotic behavior of dissipative kinetic equations

The present notes are intended to present a detailed review of the existing results in dissipative kinetic theory which make use of the contraction properties of two main families of probability metrics: optimal mass transport and Fourier-based metrics. The first part of the notes is devoted to a self-consistent summary and presentation of the properties of both probability metrics, including new aspects on the relationships between them and other metrics of wide use in probability theory. These results are of independent interest with potential use in other contexts in Partial Differential Equations and Probability Theory. The second part of the notes makes a different presentation of the asymptotic behavior of Inelastic Maxwell Models than the one presented in the literature and it shows a new example of application: particle's bath heating. We show how starting from the contraction properties in probability metrics, one can deduce the existence, uniqueness and asymptotic stability in classical spaces. A global strategy with this aim is set up and applied in two dissipative models.

HCV infection after liver transplantation is associated with lower levels of alloreactive CD4+CD25+CD45RO+IL-7R+high+ T cells

Aim: Expression of IL-7R discriminates alloreactive CD4 T cells (Foxp3 negative), from IL-7Rlow regulatory CD4 T cells (Foxp3 positive). Chronic hepatitis C virus infection (HCV) reduces expression of IL-7R on T cells thus promoting persistence of infection. The aim of this study was to analyze the effect of HCV infection on the expression of IL-7R of activated CD4+ T cells in liver transplant patients. Patients and methods: We analyzed PBMC from liver transplant recipients for the expression of CD4, CD25, FoxP3, IL-7R (24 HCV negative and 29 HCV-chronically infected). We compared these data with non-transplanted individuals (52 HCV-chronically infected patients and 38 healthy donors). Results: In HCV-infected liver transplant recipients, levels of CD4+CD25+CD45RO+IL-7R+ T cells were significantly reduced (10.5+/-0.9%) when compared to non-HCV-infected liver transplant recipients (17.6+/-1.4%) (P<0.001), while both groups (HCV-infected and negative transplant recipients) had significantly higher levels than healthy individuals (6.6+/-0.9%) (P<0.0001). After successful antiviral therapy (sustained antiviral response), 6 HCV-infected transplant recipients showed an increase of CD4+CD25+CD45RO+IL-7R+ T cells, reaching levels similar to that of non-HCVinfected recipients (10.73+/-2.63% prior therapy versus 21.7+/-6.3% after clearance of HCV). (P<0.05) In 4 non-responders (i.e. HCVRNA remaining present in serum), levels of CD4+CD25+CD45RO+IL-7R+ T cells remained unmodified during and after antiviral treatment (11.8+/- 3.3% versus 11.3+/-3.3% respectively). Conclusions: Overall, these data indicate that CD4+CD25+CD45RO+IL-7R+ T cells appear to be modulated by chronic HCV infection after liver transplantation. Whether lower levels of alloreactive T cells in HCV-infected liver transplant recipients are associated with a tolerogenic profile remains to be studied.
