Experiencias de inclusión: Presentación.

La mejor manera de entender la inclusión educativa es viéndola como un proceso. En efecto, no hace mucho más de una década que empezó a hablarse de la escuelanclusiva como de una forma de superación de determinadas concepciones dentegración educativa en las que poníamos (debemos hablar en primera persona, por supuesto) demasiado énfasis en el carácter diferencial de las necesidades de determinados alumnos y en el carácterndividualizado de los apoyos requeridos

Two types of empirical relation governing the variation of permittivity with fractional weight of the binders have been tried. Parameters involved in only one type of formulation have been evaluated by the usual curve fitting using non-linear regression method’. Correlation of parameters with the nature of the binders has also been attempted.</span

Exploration of crossover criticality in an aqueous electrolyte solution

The light scattering measurements that yield the osmotic susceptibility (chi(T)) in a ternary liquid mixture of 3-methylpyridine + water + sodium bromide are presented. The measurements have been performed in the one-phase region near the lower consolute points T-L's of samples with different concentrations (X) of NaBr. The data analysis has been performed by incorporating both one and ntwo correction-to-scaling terms. Results indicate that for large concentrations of NaBr, two correction-to-scaling terms are necessary for a proper description of the data. Moreover, it is observed that the amplitude of the first correction-to-scaling term (chi(1)) is negative for all the cases studied. These results are interpreted as a nonmonotonic crossover of the effective susceptibility exponent, gamma(eff), from its Ising value of 1.24 to the mean-field value of 1.00, when moving away from a given T-L. Investigations on the existence of an additional length scale in this mixture, using excess molar volume measurements, are also reported

Mechanism design for green, truthful procurement auctions

Auction based mechanisms have become popular in industrial procurement settings. These mechanisms minimize the cost of procurement and at the same time achieve desirable properties such as truthful bidding by the suppliers. In this paper, we investigate the design of truthful procurement auctions taking into account an additional important issue namely carbon emissions. In particular, we focus on the following procurement problem: A buyer wishes to source multiple units of a homogeneous item from several competing suppliers who offer volume discount bids and who also provide emission curves that specify the cost of emissions as a function of volume of supply. We assume that emission curves are reported truthfully since that information is easily verifiable through standard sources. First we formulate the volume discount procurement auction problem with emission constraints under the assumption that the suppliers are honest (that is they report production costs truthfully). Next we describe a mechanism design formulation for green procurement with strategic suppliers. Our numerical experimentation shows that emission constraints can significantly alter sourcing decisions and affect the procurement costs dramatically. To the best of our knowledge, this is the first effort in explicitly taking into account carbon emissions in planning procurement auctions
