Utilización de la Historia de las Matemáticas en clase con alumnos de 6 a 13 años

En mi conferencia consideraré varias maneras de utilizar la historia de las matemáticas en la didáctica de las matemáticas para la escuela obligatoria; se trata de experiencias y reflexiones relacionadas con la elaboración y la experimentación de currículos para la enseñanza de las Matemáticas en las edades comprendidas entre los 6 y los 13 años, desarrollados a partir de 1975 en el grupo de universitarios y enseñantes que coordino personalmente en Génova. El trabajo se ha efectuado en colaboración con Elda Guala; algunos artículos relacionados con estas cuestiones ya han sido publicados o están en curso de publicación.

Distributed belief revision as applied within a descriptive model of jury deliberations

Belief revision is a well-research topic within AI. We argue that the new model of distributed belief revision as discussed here is suitable for general modelling of judicial decision making, along with extant approach as known from jury research. The new approach to belief revision is of general interest, whenever attitudes to information are to be simulated within a multi-agent environment with agents holding local beliefs yet by interaction with, and influencing, other agents who are deliberating collectively. In the approach proposed, it's the entire group of agents, not an external supervisor, who integrate the different opinions. This is achieved through an election mechanism, The principle of "priority to the incoming information" as known from AI models of belief revision are problematic, when applied to factfinding by a jury. The present approach incorporates a computable model for local belief revision, such that a principle of recoverability is adopted. By this principle, any previously held belief must belong to the current cognitive state if consistent with it. For the purposes of jury simulation such a model calls for refinement. Yet we claim, it constitutes a valid basis for an open system where other AI functionalities (or outer stiumuli) could attempt to handle other aspects of the deliberation which are more specifi to legal narrative, to argumentation in court, and then to the debate among the jurors.

Healthcare: rejection of privatisation and patient fees in Central Europe

Since 2006, there have been successful campaigns against commercialisation of public health services in the four central European countries – Czech Republic, Hungary, Poland and Slovakia.

Deal or no deal

Discusses the pre-action protocol for mortgage possession claims which came into effect on November 19, 2008, highlighting the situations in respect of which it is suggested the lender "considers" not starting proceedings and the lenders entitlement to be informed of progress on the sale of the property. Reviews the guidance on mortgages and arrears issued by the Council for Mortgage Lenders, aimed at assisting lenders in complying with the Financial Services Agency's Mortgage Conduct of Business Rules Pt 13.

Intracellular fate of bioresponsive poly(amidoamine)s in vitro and in vivo

Linear poly(amidoamine)s (PAAs) have been designed to exhibit minimal non-specific toxicity, display pH-dependent membrane lysis and deliver genes and toxins in vitro. The aim of this study was to measure PAA cellular uptake using ISA1-OG (and as a reference ISA23-OG) in B16F10 cells in vitro and, by subcellular fractionation, quantitate intracellular trafficking of (125)I-labelled ISA1-tyr in liver cells after intravenous (i.v.) administration to rats. The effect of time after administration (0.5-3h) and ISA1 dose (0.04-100mg/kg) on trafficking, and vesicle permeabilisation (N-acetyl-b-D-glucosaminidase (NAG) release from an isolated vesicular fraction) were also studied. ISA1-OG displayed approximately 60-fold greater B16F10 cell uptake than ISA23-OG. Passage of ISA1 along the liver cell endocytic pathway caused a transient decrease in vesicle buoyant density (also visible by TEM). Increasing ISA1 dose from 10mg/kg to 100mg/kg increased both radioactivity and NAG levels in the cytosolic fraction (5-10 fold) at 1h. Moreover, internalised ISA1 provoked NAG release from an isolated vesicular fraction in a dose-dependent manner. These results provide direct evidence, for the first time, of PAA permeabilisation of endocytic vesicular membranes in vivo, and they have important implications for potential efficacy/toxicity of such polymeric vectors.

Evidence for the Confraternity of S. Pietro Martire at San Zanipolo, Venice

This conference paper looks at evidence of 15th- and 16th-century saints' images on carved door frames at the church of S. Zanipolo (SS Giovanni e Paolo) in Venice, using them to help locate and reconstruct the history of the 'albergo' of the confraternity dedicated to St Peter Martyr and St Vincent Ferrer. Suggestions are made concerning the possible relationship of confraternity buildings outside a church to altars dedicated to the same saint(s) within that church.
