L’acceptation de l’homosexualité et de l’adoption par les couples homosexuels à six mois de l’élection présidentielle de 2012

Premières lignes : L’acceptation croissante de l’homosexualité et, dans une moindre mesure de l’homoparentalité, sont révélatrices de l’évolution des valeurs dans les sociétés démocratiques. Ronald Inglehart[1] met ainsi en évidence la transformation des systèmes de valeurs des citoyens des démocraties occidentales. Cela constituerait une « révolution silencieuse »[2] marquée par le passage de valeurs matérialistes à des valeurs post-matérialistes. Ces évolutions possèdent des conséquences politiques dans la mesure où le post-matérialisme est vecteur de nouveaux clivages sociopolitiques. Si l’homoparentalité est apparue comme un enjeu lors des élections présidentielles de 2007, aucune avancée législative concernant la reconnaissance des droits des couples homosexuels n’a été observée en France depuis le PaCS en 1999. Or, la mobilisation, notamment associative, sur ces enjeux reste importante, en témoigne le mot d’ordre de la dernière marche des fiertés LGBT en 2011 : « Pour l’égalité : en 2011 je marche, en 2012 je vote ». Nous nous attacherons, dans le contexte pré-électoral, à étudier, au-delà de l’acceptation croissante des enjeux associés à l’homosexualité et à l’homoparentalité, la persistance des dynamiques sociales et politiques permettant de comprendre les différents niveaux d’acceptation de l’homosexualité comme manière de vivre sa vie et du droit d’adopter pour les couples homosexuels

Les traces de La Manif pour tous

Les élections régionales des 6 et 13 décembre 2015 interviennent peu après le troisième anniversaire du collectif de La Manif pour tous dont la première manifestation en opposition au projet de loi Taubira sur l’ouverture du mariage aux couples de même sexe se tenait le 17 novembre 2012. Quatre ans et demi après sa fondation et quatre ans après l’adoption définitive de la loi à l’Assemblée nationale le 23 avril 2013, le collectif est toujours mobilisé. L’abrogation de la loi Taubira reste au cœur des revendications du mouvement mais il s’est saisi de nouveaux enjeux. De même, ses répertoires d’action ont évolué et se sont diversifiés. La dernière manifestation de rue organisée à Paris remonte au 16 octobre 2016. Par ailleurs, plusieurs groupes affiliés au mouvement investissent l’espace public avec leurs actions. Le collectif a aussi développé ses activités de lobbying et s’est saisi de toutes les échéances électorales pour interpeller les candidats et les inviter à se prononcer sur ses revendications. Dans le cadre des élections régionales, huit meetings ont été organisés, intitulés « Questions pour un président de région », durant lesquels des têtes de liste des Républicains, de l’UDI, du MoDem, du FN et de Debout la France ont accepté de répondre aux questions axées sur les compétences des régions concernant la « vie quotidienne des familles ».

Compte-rendu de Jeunes socialistes, jeunes UMP. Lieux et processus de socialisation politique

L’ouvrage de Lucie Bargel, issu directement d’une thèse parfaitement maîtrisée, relève d’abord de l’étude de la socialisation politique secondaire puisqu’elle observe l’apprentissage en train de se faire dans ces groupes d’affinités que constituent les groupements politiques. Il participe également de l’analyse des partis politiques en se focalisant sur deux organisations de jeunesse, les Jeunes populaires (JP) et les Jeunes socialistes (MJS), donc sur des jeunes partisans d’organisations centrales peu étudiées (...)

L'appréhension par le droit de l'Union européenne des sanctions dans le domaine des activités sportives

European sport is on the verge of an upheaval as to its consideration by EU law and by the law of the European Convention on Human Rights. The finding of overlapping standards and different legal frameworks producing effects on the sanctions on the "European citizen athlete" leads to the repetition of difficulties relating to the infringement of the principles of equal treatment and of integrity of sport competitions. This thesis demonstrates the need for Europeanisation of sanctions imposed on the "European citizen athlete", and develops a reflection on the legal instruments of soft law and hard law - existing or to be developed - that may be of interest to meet that objective of Europeanisation. The originality of the work primarily lies in conducting field surveys, and secondly in the development and future changes in instruments of soft law or hard law existing for the purpose of combating violations of these principles, by contributing in various ways, to the Europeanisation of sanctions in the field of sportsLe sport européen est à la veille d'un bouleversement quant à sa prise en compte par le droit de l'UE et par le droit de la Convention européenne des droits de l’homme. Le constat du chevauchement de normes et de référentiels juridiques différents produisant des effets sur les sanctions infligées au « sportif citoyen européen » conduit à la répétition de difficultés relatives à la violation des principes d'égalité de traitement et d'intégrité des compétitions sportives. Cette thèse démontre la nécessité d'une européanisation des sanctions infligées au « sportif citoyen européen », et propose une réflexion sur les instruments juridiques de droit souple et de droit dur - existants ou à exploiter - susceptibles de répondre à cet objectif d'européanisation. L'originalité des travaux réside d'abord dans la réalisation d'enquêtes de terrain, puis dans le développement et les modifications à venir d'instruments de droit souple ou de droit dur existants, aux fins de combattre les atteintes aux principes précités en contribuant, de diverses façons, à l'européanisation des sanctions dans le domaine des activités sportive

Time resolved XANES illustrates a substrate-mediated redox process in Prussian blue cultural heritage materials

The pigment Prussian blue is studied in heritage science because of its capricious fading behavior under light exposure. We show here that XANES can be used to study the photosensitivity of Prussian blue heritage materials despite X-ray radiation damage. We used an original approach based on X-ray photochemistry to investigate in depth the redox process of Prussian blue when it is associated with a cellulosic substrate, as in cyanotypes and watercolors. By modifying cation and proton contents of the paper substrate, we could tune both rate and extent of Prussian blue reduction. These results demonstrate that the photoreduction and fading of Prussian blue is principally mediated by the substrate and its interaction with the oxygen of the environment

Light and anoxia fading of Prussian blue dyed textiles.

Although Prussian blue is a popular pigment, its stability has been questioned since its discovery in 1704. Its stability upon exposure to light and anoxia remains difficult to apprehend. The present paper focuses on the relative influences of light, anoxia and type of substrate on the discoloration of Prussian blue dyed textiles. Spectrophotometry and X-ray absorption spectroscopy measurements of samples artificially aged by light in air or anoxia show that both the extent of the reduction process at the origin of Prussian blue discoloration and the aging of the textile substrate are linked and strongly differ with the environment. The complex inter-relationship existing between Prussian blue discoloration and textile degradation and the final impact it may have on the conservation of the entire system is discussed

Toward a typeface for the transcription of facial actions in sign languages

International audienceNon-manual actions, and more specifically facial actions (FA) can be found in all Sign Languages (SL). Those actions involve all the different facial parts and can have various and intricate linguistic relations with manual signs. Unlike in vocal languages, FA in SL provide more meaning than simple expressions of feelings and emotions. Yet non-manual parameters are among the most unknown formal features in SL studies. During the past 30 years, some studies have started questioning the meanings and linguistic values and the relations between manual and non-manual signs (Crashborn et al. 2008; Crashborn & Bank 2014); more recently, SL corpora have been analysed, segmented, and transcribed to help study FA (Vogst-Svenden 2008; Bergman et al. 2008; Sutton-Spence & Day 2008).Moreover, to fill the lack of an annotation system for FA, a few manual annotation systems have integrated facial glyphs, such as HamNoSys (Prillwitz et al. 1989) and SignWriting (Sutton 1995). On one hand, HamNoSys has been developed to describe all existing SLs at a phonetic level; it allows a formal, linear, highly detailed and searchable description of manual parameters. As for non-manual parameters, HamNoSys offers the replacement of hands by another articulators. Non-manual parameters can be written as “eyes” or “mouth” and described by the same symbols developed for hands (Hanke 2004). Unfortunately only a limited number of manual symbols can be translated into FA and the annotation system remains incomplete. On the other hand, SignWriting describes SL with iconic symbols placed in a 2D space representing the signer’s body. Facial expressions are divided into mouth, eyes, nose, eyebrows, etc., and are drawn in a circular “head” much like emoticons. SignWriting offers a detailed description of posture and actions of non-manual parameters, but does not ensure compatibility with the most common annotation software used by SL linguists (e.g., ELAN).Typannot, a interdisciplinary project led by linguists, designers, and developers, which aims to set up a complete transcription system for SL that includes every SL parameter (handshape, localisation, movement, FA), has developed a different methodologie. As mentioned earlier, FA have various linguistic values (mouthings, adverbial mouth gestures, semantically empty, enacting, whole face) and also include prosody and emotional meanings. In this regard, they can be more variable and signer-related than manual parameters. To offer the best annotation tool, Typannot’s approach has been to define facial parameters and all their possible tangible configurations. The goal is to set up the most efficient, simple, yet complete and universal formula to describe all possible FA.This formula is based on a 3 dimensional grid. Indeed all the different configurations of FA can be described by its X, Y, Z axis position. As a result, all FA can be described and encoded using a restricted list of 39 qualifiers. Based on this model and to help reduce the annotation process, a set of generic glyphs has been developed. Each qualifier has its own symbolic “generic” glyph. This methodical decomposition of all facial components enables a precise and accurate transcription of a complex FA using only a few glyphs.This formula and its generic glyphs have gone through a series of tests and revisions. Recently, an 18m20s long FA corpus of two deaf signers has been recorded using two different cameras. The first one, RGB HQ, is used to capture a high quality image and the second, infrared Kinect, is used to captured the depth. The latter was linked with Brekel Proface 2 (Leong et al. 2015), a 3D animation software that enables an automatic recognition of FA. This corpus has been fully annotated using Typannot’s generic glyphs. These annotations have enabled the validation of the general structure of Typannot FAformula and to identify some minor corrections to be made. For instance, it has been shown that the description of the air used to puff out or suck in cheeks is too restrictive and the description of the opening and closure of the eyelids is too unnecessarily precise.When those changes are implemented, our next task will be to develop a morphological glyphic system that will combine the different generic glyphs used for each facial parameter into one unique morphological glyph. This means that for any given FA, all the information contained in Typannot descriptive formula will be contained within one legible glyph. Some early research and work has already begun on this topic, but needs further development before providing a statement on its typographic structure. When this system is completed, it will be released with its own virtual keyboard (Typannot Keyboard, currently in development for handshapes) to help transcription and improve annotation processes.Bibliography :-Chételat-Pelé, E.

Trace elements discriminate between tissues in highly weathered fossils

Palaeontologists assess the affinities of fossils using either morphology-based phylogenetic analyses, possibly enhanced by the use of advanced imaging techniques, or the identification of remnants or derivatives of fossil organic molecules with high taxonomic specificity (“biomarkers”). However, these approaches are often of little use for the majority of fossils whose original morphology and chemistry have been severely altered or completely lost during decay, diagenesis and modern weathering. Here we show that the inorganic incorporation of trace elements during fossilization and diagenesis can be used to assess the affinity of highly altered fossils, constituting a powerful tool overlooked so far. This is illustrated by the study of a wide range of animals from the Early Ordovician Fezouata Shale (Tremadocian, Morocco) using synchrotron X-ray fluorescence major-to-trace elemental mapping. Although all fossils studied here have turned into iron oxides, spectral analyses reveal that their different tissue types (i.e. biomineralised, sclerotised, cuticularised, and internal tissues) can be distinguished on the basis of their trace element inventories. The resulting elemental classes and distributions allowed us to identify an enigmatic, highly weathered organism as a new stem euarthropod preserving remains of its nervous system

Study of the influence of physical, chemical and biological conditions that influence the deterioration and protection of Underwater Cultural Heritage

Two wrecks related to the Battle of Trafalgar (1805) were studied. Following the guidelines of the UNESCO-2001 Convention for the Protection of the Underwater Cultural Heritage, a holistic and interdisciplinary approach based on the development of four of the thirty-six Rules of this international agreement was applied. A non-destructive survey technique was developed to obtain information from the scattered cannons and anchors without altering their condition (Rule 4). The work performed provided information about the origin of both wrecks, the Fougueux and the Bucentaure, two ships of the line of the French Navy, and allowed to characterize the state of conservation at each site without jeopardizing their future conservation in the marine environment. In addition, measurements of the main physical, chemical and biological variables allowed correlating the conservation status at each site with the marine environmental conditions (Rule 15). Thus, in Fougueux shipwreck large iron objects are corroding at a higher rate (between 0.180 and 0.246 mmpy) due to high sediment remobilization and transport induced by waves at this site, causing damage by direct mechanical effect on metallic material and by removing the layer of corrosion products developed on the artefacts. Meanwhile artillery on Bucentaure site, covered with thick layers of biological concretion, is well preserved, with lower corrosion rates (0.073 to 0.126 mmpy), and archaeological information is guaranteed. Finally, the effectiveness of the cathodic protection as a temporary measure for in situ conservation (Rule 1) was evaluated on a cannon. The use of a sacrificial anode after 9 months reduced the average corrosion rate (from 0.103 to 0.064 mmpy) and the percent of corrosion rate in 37.9%. These results are very useful for developing a decision making system of the Site Management Program, based on predictive models of artefacts permanence and risk factors in the marine environment (Rule 25)
