Blâmée par Jules Michelet, en raison d'un goût que l'historien du XIXe siècle estime trop prononcé pour les intrigues, Louise de Savoie (1476-1531) est sans conteste l'une des personnalités les plus fascinantes de la première Modernité européenne. Comtesse puis duchesse d'Angoulême, Louise n'est pas seulement la mère de deux illustres enfants, Marguerite et François, futur François Ier. Elle se charge de leur éducation ; une fois son fils devenu le roi de France, elle devient un conseiller des plus influents, avant d'assurer, à deux reprises, la régence du royaume. Amatrice d'art et bibliophile avertie, son action concerne encore la musique, la littérature et l'architecture. Les textes rassemblés dans cet ouvrage - issu d'un colloque tenu, en décembre 2010, à Romorantin-Lanthenay, où Louise possédait le château et des terres sur lesquelles Léonard de Vinci avait projeté d'édifier une ville nouvelle pour la cour - ambitionnent de passer en revue tant les aspects biographiques du personnage, que son action dans le champ politique, religieux et culturel.

The main objective of this document is to establish if the UE can be considered as an actor of the Latin-American regional integration. The method of the current research is qualitative. The different aspects of the interregional European strategy for regional integration towards Latin America (E.I.S.R.I. – L.A.) are analyzed as follows. First, the discourse that places regional integration as one of the priorities of the given strategy is studied. Second, the economic actions responsible of materializing that priority are checked. Third, the political actions of the E.I.S.R.I. – L.A. are introduced. The results of the analysis make it evident that although EU appears to be an actor of the Latin-American regional integration, its influence seems to be restricted. Nevertheless, this affirmation should be relativized because this lack of influence can be due to an absence of mechanisms of measurement of results in terms of regional integration. [less ▲]

Through their different encounters with union, court, and government equality agency lawyers, workers report diverse understandings of their personal experience of injustice in the workplace. This paper examines workers’ experiences of discrimination and the role legal professionals play in litigating these issues in Belgium. Bringing together legal and rights consciousness studies and the sociology of intermediation and tracking different stages in the construction of discrimination cases, from the moment when a future litigant describes an event as an injustice to the moment when the judge recognises a discriminatory behaviour (or conversely, dismisses a case), we suggest several possible empirical explanations of the way in which interactions with legal intermediaries affect workers’ rights consciousness. Because we refer to socio-legal studies from common law countries, this paper also calls into question how best to import these studies to assist in analysing legal mobilisations and legal consciousness in continental Europe.

Historical soil contamination within a 3 km radius of a former ore treatment plant was evaluated. A total of 247 topsoil samples were collected in a stratified random sampling design taking into account three factors: land use (LU), soil type (ST) and wind direction (WD). Concentrations of trace elements (Cd, Co, Cr, Cu, Ni, Pb and Zn) and major elements (Ca, Mg, K, Fe, Al, Mn) as well as various soil properties (pHwater, pHKCl, TOC and N) were measured. Total Cd, Pb and Zn concentrations were higher than typical background values. Enrichment factors for these three metals were, respectively, 260, 77.4 and 35.5. Principal components analysis (PCA) and factor analysis segregated anthropogenic contamination as a premier factor in influencing concentrations, followed by a second lithogenic factor. The anthropogenic origin of substantial contamination was confirmed though mapping of sample locations relative to contaminant sources. Factor 1 (26.5% of the variance) impacts a large area around the contaminated site and is also indicative of WD influence. Factor 2 (23.9% of the variance) is naturally linked to the local lithology and geology. LU and soil fertility are, respectively, represented by factor 3 (16.5% of the variance), which is linked to pH, and factor 4 (9.3% of the variance), related to organic content. The significance of landscape factors in the spatial distribution of metallic trace elements (MTE) was assessed with an ANCOVA using “distance to the source” as a covariate. Results of the analysis support the hypothesis that Cd, Cu, Pb and Zn concentrations are mainly driven by anthropogenic factors, specifically historical industrial activity at the former ore treatment plant. The ANCOVA also provides a means to quantify the impact of LU and ST as well, particularly on MTE availability in soils. The presence of MTE in soil poses known, and potentially significant, risks to both human health and the environment. [less ▲]

We develop a method for computing facet-defining valid inequalities for any mixed-integer set PJ. Our practical implementation does not return only facet- defining inequalities, but it is able to find a separating cut whenever one exists. The separator is not comparable in speed with the specific cutting-plane generators used in branch-and-cut solvers, but it is general-purpose. We can thus use it to compute cuts derived from any reasonably small relaxation PJ of a general mixed- integer problem, even when there exists no specific implementation for computing cuts with PJ. Exploiting this, we evaluate, from a computational perspective, the usefulness of cuts derived from several types of multi-row relaxations. In particular, we present results with four different strengthenings of the two-row intersection cut model, and multi-row models with up to fifteen rows. We conclude that only fully-strengthened two-row cuts seem to offer a significant advantage over two-row intersection cuts. Our results also indicate that the improvement obtained by going from models with very few rows to models with up to fifteen rows may not be worth the increased computing cost. [less ▲]

Context. GJ 436b is one of the few transiting warm Neptunes for which a detailed characterisation of the atmosphere is possible, whereas its non-negligible orbital eccentricity calls for further investigation. Independent analyses of several individual datasets obtained with Spitzer have led to contradicting results attributed to the different techniques used to treat the instrumental effects. Aims. We aim at investigating these previous controversial results and developing our knowledge of the system based on the full Spitzer photometry dataset combined with new Doppler measurements obtained with the HARPS spectrograph. We also want to search for additional planets. Methods. We optimise aperture photometry techniques and the photometric deconvolution algorithm DECPHOT to improve the data reduction of the Spitzer photometry spanning wavelengths from 3-24 {\mu}m. Adding the high precision HARPS radial velocity data, we undertake a Bayesian global analysis of the system considering both instrumental and stellar effects on the flux variation. Results. We present a refined radius estimate of RP=4.10 +/- 0.16 R_Earth, mass MP=25.4 +/- 2.1 M_Earth and eccentricity e= 0.162 +/- 0.004 for GJ 436b. Our measured transit depths remain constant in time and wavelength, in disagreement with the results of previous studies. In addition, we find that the post-occultation flare-like structure at 3.6 {\mu}m that led to divergent results on the occultation depth measurement is spurious. We obtain occultation depths at 3.6, 5.8, and 8.0 {\mu}m that are shallower than in previous works, in particular at 3.6 {\mu}m. However, these depths still appear consistent with a metal-rich atmosphere depleted in methane and enhanced in CO/CO2, although perhaps less than previously thought. We find no evidence for a potential planetary companion, stellar activity, nor for a stellar spin-orbit misalignment. [ABRIDGED] [less ▲]

Apple (Malus sp.) is among the most processed fruit that generates high amount of wastes. Depending on processes, various by-products are available offering a great diversity of low-cost raw materials. Biorefinery processes are expected to convert them into new added-value products such as hemicelluloses, oligosaccharides and polyphenols. This paper reviews the current uses of apple by-products as source of fibre and phytochemicals with special emphasis on recent fractionation processes. Future trends and challenges of apple by-product reuse are discussed. [less ▲]

A variable-resolution atmospheric general circulation model (AGCM) is used for climate change projections over the Antarctic. The present-day simulation uses prescribed observed sea-surface conditions, while a set of five simulations for the end of the 21st century (2070-2099) under the SRES-A1B scenario uses sea- surface condition anomalies from selected CMIP3 coupled ocean-atmosphere climate models. Analysis of the results shows that the prescribed sea-surface condition anomalies have a very strong influence on the simulated climate change on the Antarctic continent, largely dominating the direct effect of the prescribed greenhouse gas concentration changes in the AGCM simulations. Complementary simulations with idealized forcings confirm these results. An analysis of circulation changes using self-organizing maps shows that the simulated climate change on regional scales is not principally caused by shifts of the frequencies of the dominant circulation patterns, except for precipitation changes in some coastal regions. The study illustrates that in some respects the use of bias-corrected sea- surface boundary conditions in climate projections with a variable-resolution atmospheric general circulation model has some distinct advantages over the use of limited-area atmospheric circulation models directly forced by generally biased coupled climate model output.
