Recent studies in high-income industrialized countries have shown that equivalence scales are income-dependent. We investigate whether this dependence also holds in poorer, services oriented countries, by considering the example of Cyprus. We also examine whether household economies of scale and relative children costs differ. [less ▲]

Aujourd'hui l'analyse sociologique permet d'envisager la consommation de psychotropes par les seniors comme une caractéristique de nos sociétés modernes contemporaines. Le recours à ces médicaments est devenu l'une des clefs de la compréhension des comportements occidentaux où la recherche de bien-être physique, mental et social à tout prix est ressentie comme une nécessité avérée.Comment les consommateurs parviennent-ils à gérer leur consommation au point de la considérer comme non problématique ? Quelles attitudes pratiques et symboliques mettent-ils en œuvre pour y parvenir ? Est-il réellement possible de gérer son rapport à des produits intrinsèquement générateurs de dépendance ? Existe-t-il vraiment des personnes capables de contrôler leur consommation de psychotropes au point de la rendre compatible avec un mode de vie détaché de la dépendance à ce produit ? Existe-t-il une consommation invisible en raison même de son caractère non problématique pour les seniors ? Avec l'aide du psychotrope ne s'agit-il donc pas de rendre supportable et acceptable les effets du stigmate vécus par les seniors qui glissent peu à peu hors de la sphère productive ? La prescription de ces médicaments n'amène-t-elle pas à traduire des défaillances personnelles, des problèmes d'ordre social en besoin de solutions biomédicales ? Au-delà de cette médicalisation, ne doit-on pas également voir ces substances comme des moyens permettant de mieux répondre à la demande de performance définissant la normativité contemporaine ? Cette consommation ne révèle-t-elle pas une attitude de démission thérapeutique de la part des professionnels de la santé ? Les objectifs de ce travail ont été d’analyser les valeurs attribuées aux psychotropes, à la dépendance et le sens que les consommateurs et les consommatrices ayant une trajectoire continue ou occasionnelle donnent aux recours à ces médicaments.

We present ab initio calculations of the nonresonant Raman spectra of zigzag and armchair BN nanotubes. In comparison, we implement a generalized bond-polarizability model where the parameters are extracted from first-principles calculations of the polarizability tensor of a BN sheet. For light polarization along the tube axis, the agreement between model and ab initio spectra is almost perfect. For perpendicular polarization, depolarization effects have to be included in the model in order to reproduce the ab initio Raman intensities. [less ▲]

present calculations for the optical absorption spectra of hexagonal boron nitride (hBN) and BN nanotubes, using many-body perturbation theory. Solution of the Bethe-Salpeter equation for hBN leads to optical absorption and loss spectra where the positions and shapes of the peaks are strongly dominated by excitonic effects. The binding energy of the first exciton is about 0.71 eV. Comparison of the calculations with recently measured optical absorption and EELS demonstrates that DFT underestimates the "true" band gap of BN by 2.25 eV. This band gap difference can be partially (hot not completely) reproduced by a calculation of the quasi-particle band-structure on the level of the GW-approximation. We show, how the lower dimensionality of BN nanotubes leads to a much stronger excitonic binding energy and at the same time to a larger quasi-particle gap. This leaves the position of the first absorption peak almost unchanged. However, the difference in the series of excitonic peaks allows the spectroscopic distinction between BN nanotubes and bulk BN.

To ensure the long-time stability of the terrestrial reference system with an accuracy of 10‑9 in the global and continental scale, the interactions between different time-dependent influences of the system Earth to the terrestrial reference system and the related observation has to be considered in the evaluation models. It is proposed to establish a kinematic European Combined Geodetic Network (ECGN) and to integrate the spatial and height reference system into the Earth gravity field parameter estimation. This plan is in agreement with the foreseen IAG project of an Integrated Global Geodetic Observation System (IGGOS). In selected European stations ECGN will establish the combination of time series of spatial/geometric GNSS observations, precise levelling and tide gauge records with gravity field related observations (gravity, Earth tides). Observations are complemented with meteorological parameters, surrounding information of the stations, e.g. eccentricities and ground water level. A first call for participation in the project was directed to the implementation of the ECGN stations. These stations include the standard observation techniques GNSS (GPS/GLONASS—permanent), gravity (super conducting gravimeter and/or absolute gravimeter—permanent or repeated), levelling connections to nodal points of the European levelling network (UELN) (repeated) and meteorological parameters (permanent). A basic constituent of the ECGN stations is a local network for controlling the eccentricities at the 1 mm accuracy level in all three spatial components. For the contributing observation techniques, guidelines have been agreed upon to ensure equal observation principles [less ▲]

A number of RGD-type integrins rely on a synergistic site in addition to the canonical RGD site for ligand binding and signaling, although it is still unclear whether these two recognition sites function independently, synergistically, or competitively. Experimental evidence has suggested that fibrinogen binding to the RGD-type integrin alphaIIbbeta3 occurs exclusively through the synergistic gamma(400-411) sequence, thus questioning the functional role of the RGD recognition site. Here we have investigated the respective role of the fibrinogen gamma(400-411) sequence and the RGD motif in the molecular events leading to ligand-induced alphaIIbbeta3-dependent Chinese hamster ovary (CHO) cell or platelet spreading, by using intact fibrinogen and well characterized plasmin-generated fibrinogen fragments containing either the RGD motif (fragment C) or the gamma(400-411) sequence (fragment D), and CHO cells expressing resting wild type (alphaIIbbeta3wt), constitutively active (alphaIIbbeta3T562N), or non-functional (alphaIIbbeta3D119Y) receptors. Our data provide evidence that the gamma(400-411) site by itself is able to initiate alphaIIbbeta3 clustering and recruitment of intracellular proteins to early focal complexes, mediating cell attachment, FAK phosphorylation, and Rac1 activation, while the RGD motif subsequently acts as a molecular switch on the beta3 subunit to trigger cell spreading. More importantly, we show that the premier functional role of the RGD site is not to reinforce cell attachment but, rather, to imprint a conformational change on the beta3 subunit leading to maximal RhoA activation and actin cytoskeleton organization in CHO cells as well as in platelets. Finally, alphaIIbbeta3-dependent RhoA stimulation and cell spreading, but not cell attachment, are Src-dependent and phosphoinositide 3-kinase-independent and are inhibited by the Src antagonist PP2.

Within a group of cooperating agents the decision making of an individual agent depends on the actions of the other agents. In dynamic environments, these dependencies will change rapidly as a result of the continuously changing state. Via a context-specific decomposition of the problem into smaller subproblems, coordination graphs offer scalable solutions to the problem of multiagent decision making. In this work, we apply coordination graphs to a continuous (robotic) domain by assigning roles to the agents and then coordinating the different roles. Moreover, we demonstrate that, with some additional assumptions, an agent can predict the actions of the other agents, rendering communication superfluous. We have successfully implemented the proposed method into our UvA Trilearn simulated robot soccer team which won the RoboCup-2003 World Championship in Padova, Italy. (C) 2004 Elsevier B.V.

Cardiomyocytes are notoriously difficult to transfect using standard techniques unless viral vectors such as recombinant adenoviruses are used. Generation of recombinant adenoviruses is, however, a complex and time-consuming procedure and not possible for every DNA construct. We therefore optimized DNA/polylysine/adenovirus complexing for efficient gene transfer in neonatal rat cardiomyocytes determining the critical parameters for this method. Importantly, not only the concentration of the various components but also the method used for plasmid purification is critical for this transfection technique. Cesium-chloride-purified DNA is inferior to anion-exchange methods for this purpose possibly because of altered ionic properties. In the second part of this study, we could demonstrate silent gene transfer into cardiomyocytes applying this optimized technique to plasmids encoding luciferase or beta-galactosidase cDNAs under the control of the cytomegalovirus immediate-early promoter. Phorbol myristate acetate and/or forskolin increased the amount of beta-galactosidase positive cells up to fivefold. Luciferase activity could even be increased as much as ninefold. These results demonstrate that the cytomegalovirus promoter is not maximally active in neonatal rat cardiomyocytes under basal conditions. In fact, a large proportion of cells is silently transfected and seems to express (an) inhibitor(s) of transcription from the CMV promoter that can be overcome by stimulation of cAMP- or protein kinase C-dependent pathways.

This is the report of a workshop organised by the European Centre for the Validation of Alternative Methods (ECVAM). ECVAM's main goal, as defined in 1993 by its Scientific Advisory Committee, is to promote the scientific and regulatory acceptance of alternative methods that are of importance to the biosciences and which replace, reduce or refine the use of laboratory animals. One of the first priorities set by ECVAM was the implementation of procedures that would enable it to become well informed about the state-of-the-art of non-animal test development and validation, and the potential for the possible incorporation of alternative tests into regulatory procedures. It was decided that this would be best achieved by the organization of ECVAM workshops on specific topics, at which small groups of invited experts would review the current status of various types of in vitro tests and their potential uses, and make recommendations about the best ways forward (Anonymous, 1994). The workshop on "The use of in vitro systems for evaluating Immunotoxicity" was held at ECVAM (Ispra), Italy, on 24th-26th November 2003. The participants represented academia, national organizations, international regulatory bodies and industry. The aim of the workshop was to review the state-of-the-art in the field of in vitro immunotoxicology, and to develop strategies towards the replacement of in vivo testing. At the end of this report are listed the recommendations that should be considered for prevalidation and validation of relevant and reliable procedures, that could replace the use of animals in chemical and cosmetics toxicity testing.
