Normes et formes de l'intérêt et du désintéressement à l'heure de la marchandisation du lien communautaire
2016
Market exchanges would be evolving into a more horizontal and collaborative model. We can notice the strength of this movement within 2.0 merchant platforms. Then, we propose to explore the tension between giving and commodification through the concepts of interest and empowerment. Our main hypothesis is about a reconfiguration of online giving in a form of "disinterested interest". We will bring this issue through an exploratory study on Airbnb.
Temas e interpretaciones del derecho sucesorio italiano
2021
El articulo quiere mostrar que las interpretaciones de las instituciones del derecho de sucesiones que consideran el interés familiar, como expresión del principio de solidaridad (cada vez más en una protección patrimonialista de la legitimidad), siempre prevalente sobre todos los demás intereses, ya no pueden ser compartidas, porque la solidaridad no se distingue del personalismo. Modernizar el derecho de sucesiones no significa tener que abdicar en favor del contrato, sino descubrir el valor de la autonomía privada y el potencial del acto de última voluntad. Es la centralidad de la persona humana y no sólo el principio de solidaridad (más aún si se entiende en un sentido patrimonialista) …
Mujeres e Ilustración: una perspectiva europea
2008
Este artículo sitúa la relación entre mujeres e Ilustración en España dentro de su contexto internacional, desde un tripe enfoque: en primer lugar, situando la trayectoria de los estudios en el marco de la historiografía europea y norteamericana; en segundo lugar, señalando las conexiones entre los debates acerca de la naturaleza y funciones de los sexos dentro y fuera de nuestras fronteras (a través de traducciones, citas e influencias mutuas) y, por último, revisando cómo para ls gentes de la época las relaciones entre hombres y mujeres constituyeron un elemento clave a la hora de valorar las diferencias nacionales y el grado de civilización alcanzado por una sociedad. En este sentido, se…
Women-translators in Russia
2011
The paper considers the history of women’s involvement in translation in Russia. The emphasis is laid on social issues of women translators’ work. The main problems discussed are as follows: How have women contributed to social and literary processes? To what extent were translational activities of women different and/or separate from those of men? Women participated in all major social processes in Russian and Soviet history. From the eighteenth century onwards to the present day, they have been involved in translational work and other types of social-systemic transfer (primarily from the West). Women played their role of translators in the same spheres where men did.
Crystallization of hard spheres revisited. II. Thermodynamic modeling, nucleation work, and the surface of tension
2018
Combining three numerical methods (forward flux sampling, seeding of droplets, and finite-size droplets), we probe the crystallization of hard spheres over the full range from close to coexistence to the spinodal regime. We show that all three methods allow us to sample different regimes and agree perfectly in the ranges where they overlap. By combining the nucleation work calculated from forward flux sampling of small droplets and the nucleation theorem, we show how to compute the nucleation work spanning three orders of magnitude. Using a variation of the nucleation theorem, we show how to extract the pressure difference between the solid droplet and ambient liquid. Moreover, combining th…
Hyperspectral imaging in perfusion and wound diagnostics – methods and algorithms for the determination of tissue parameters
2018
Abstract Blood perfusion is the supply of tissue with blood, and oxygen is a key factor in the field of minor and major wound healing. Reduced perfusion of a wound bed or transplant often causes various complications. Reliable methods for an objective evaluation of perfusion status are still lacking, and insufficient perfusion may remain undiscovered, resulting in chronic processes and failing transplants. Hyperspectral imaging (HSI) represents a novel method with increasing importance for clinical practice. Therefore, methods, software and algorithms for a new HSI system are presented which can be used to observe tissue oxygenation and other parameters that are of importance in supervising…
Polystyrene nanoparticle-templated hollow titania nanosphere monolayers as ordered scaffolds
2018
We report a novel multi-step method for the preparation of ordered mesoporous titania scaffolds and show an illustrative example of their application to solar cells. The method is based on (monolayer) colloidal nanosphere lithography that makes use of polystyrene nanoparticles organised at a water–air interface and subsequently transferred onto a solid substrate. A titania precursor solution (titanium(IV) isopropoxide in ethanol) is then drop-cast onto the monolayer and left to “incubate” overnight. Surprisingly, instead of the expected inverse monolayer-structure, a subsequent calcination step of the precursor yields an ordered monolayer of hollow titania nanospheres with a wall thickness …
Methods to Compute Pressure and Wall Tension in Fluids containing Hard Particles
2011
Colloidal systems are often modelled as fluids of hard particles (possibly with an additional soft attraction, e.g. caused by polymers also contained in the suspension). in simulations of such systems, the virial theorem cannot be straightforwardly applied to obtain the components of the pressure tensor. In systems confined by walls, it is hence also not straightforward to extract the excess energy due to the wall (the "wall tension") from the pressure tensor anisotropy. A comparative evaluation of several methods to circumvent this problem is presented, using as examples fluids of hard spheres and the Asakura-Oosawa model of colloid-polymer mixtures with a size ratio $q=0.15$ (for which th…
Remote Photoplethysmography Based on Implicit Living Skin Tissue Segmentation
2016
International audience; Region of interest selection is an essential part for remote photoplethysmography (rPPG) algorithms. Most of the time, face detection provided by a supervised learning of physical appearance features coupled with skin detection is used for region of interest selection. However, both methods have several limitations and we propose to implicitly select living skin tissue via their particular pulsatility feature. The input video stream is decomposed into several temporal superpixels from which pulse signals are extracted. Pulsatility measure for each temporal superpixel is then used to merge pulse traces and estimate the photoplethysmogram signal. This allows to select …
Preprocessing of region of interest localization based on local surface curvature analysis for three-dimensional reconstruction with multiresolution
2009
We present an approach to integrate a preprocessing step of the region of interest ROI localization into 3-D scanners laser or ste- reoscopic. The definite objective is to make the 3-D scanner intelligent enough to localize rapidly in the scene, during the preprocessing phase, the regions with high surface curvature, so that precise scanning will be done only in these regions instead of in the whole scene. In this way, the scanning time can be largely reduced, and the results contain only per- tinent data. To test its feasibility and efficiency, we simulated the prepro- cessing process under an active stereoscopic system composed of two cameras and a video projector. The ROI localization is…
