Biodiversity of the Collembola Fauna of Wetland Kerkini (N. Greece), with description of the sexual dimorphism of Entomobrya atrocincta Schött 1896 (Collembola: Entomobryomorpha)

A report on the results of a research into some aspects of the collembolan fauna of the Greek Nature Reserve associated with Lake Kerkini, known as Wetland Kerkini, is presented. The nature reserve is large and includes a wide variety of habitats, many of which were not included in this preliminary survey. From the areas sampled we recorded 44 species, of which 39 were previously described, two (Folsomia potapovi Jordana & Baquero n. sp., Entomobrya naziridisi Jordana & Baquero n. sp.), are new to science, while three are identifi ed to generic level; a further 21 are new records for Greece, and an additional 11 species are new records to the Greek Mainland. Sampling with Berlese- Tullgren funnels and Malaise traps allowed us to capture species typical of soil and species present over vegetation. This summary is based on the records held in the online database of the Fauna Europaea Project

Uneven distribution of nanoparticles in immiscible fluids: Morphology development in polymer blends

AbstractThe present review aims at summarizing the current knowledge on how solid nanoparticles organize in polymer blends. First, the behavior of low viscosity fluid emulsions containing solid colloidal particles is briefly presented. By contrast with polymer blends, they have been the subject of intensive studies for a long time, with both applicative and comprehensive objectives. High viscosity fluid emulsions like polymer blends loaded with nanofillers have received less attention until the recent enthusiasm about nanotechnology and more specifically polymer nanocomposites. Some similarities and differences between both types of emulsions are highlighted. The solid particles are well known to distribute unevenly in those types of complex fluids and the factors that determine their distribution in polymer blends are discussed. A particular emphasis is given on the competition between thermodynamic wetting of the solid by the polymeric phases and kinetic control of the filler localization directly linked to the rate of the mixing process. This aspect is believed to be a specificity of filled polymer blends and is known to have a drastic and sometimes predominant effect on particle localization. It explains that finely tuned morphologies can be obtained where the particles do not occupy their equilibrium position

Les clivages sociaux en Europe autour de la construction politique européenne en 2005-2010: l’Europe des élites contre l’État-Nation des classes populaires?

The rejection of the European Constitution by French and Dutch voters in 2005 has brought about an unprecedented crisis for European integration, with strong risks of regression into nationalism and xenophobia. However, in a paradoxical way, that crisis has not prevented the building of a political Europe - even a federal Europe - because it has hampered intergovernmental negotiations more than the functioning of European institutions. Moreover, social polarisation means that Europhiles in the élites have been able to press for institutional solutions culminating in the ratification of the Lisbon Treaty, a landmark in the consolidation of the European Union

Les périphéries espagnoles après 1978: Catalyseurs de l’intégration européenne?

Since 1978 and the return to democracy, Spain’s three main peripheral spaces from a linguistic, cultural point of view (Catalonia, the Basque Country and Galicia) have been constantly trying to get more and more autonomy from the central Spanish state. As regiones históricas (“historical regions”), they claim more competences than those enjoyed by other comunidades autónomas. That is particularly spectacular in the case of the Basque Country and Catalonia. From that perspective, belonging to the European Union was long perceived as an essential element in order to act without the Spanish state’s permission in the field of public policies. Therefore it was seen as a clearly beneficial political commitment. At a time when identities often clash in new ways, it is necessary to wonder whether those Spanish peripheral spaces go on playing such a role of catalysts of European integration

Portrait. Véronique Joumard

Depuis les années 1980, Véronique Joumard développe un travail qui identifie le faire-œuvre à sa dématérialisation, mettant en tension les polarités de l’invisible et du visible, à travers la matérialisation des flux, de l’énergie, de la lumière. L’artiste explore des médiums et des supports diversifiés (photographie, vidéo, installations, volume), faisant de la condition paradoxale du médium instable la forme même de son appareillage : de perception, de réflexion, de conduction, de lecture, ..

Les univers intérieurs de Gertrud Kolmar : à propos de Welten (1937)

En 1937, six ans avant sa mort à Auschwitz, Gertrud Kolmar écrivit à Berlin un cycle de 17 poèmes intitulé Mondes (Welten). Ces univers imaginaires dans lesquels on ne trouve pas de références explicites à la persécution nazie sont situés pour la plupart dans un ‘ailleurs’ à la fois spatial et temporel, occidental et ‘oriental’, intérieur et extérieur. Peut-on dire pour autant que Kolmar ‘se réfugie’ dans un univers irréel de création littéraire ? Si le sujet aime se présenter comme entrant dans l’espace même qu’il a construit, cet espace est toutefois marqué par la mélancolie ou l’angoisse, de sorte que s’ouvre souvent un deuxième espace, un ‘ailleurs de l’ailleurs’ qui n’est pas moins ambigu. On est en quelque sorte en présence d’un « Autre » de l’utopie qui vient jeter son ombre sur le lieu premièrement construit. Les mondes imaginés, à la beauté de pierre mais désertés par les humains, peuvent certes faire signe vers l’Être pur mais sont également associés à la mort ou à la disparition du sujet. L’écriture apparaît non pas comme une simple conduite de fuite devant les événements contemporains, mais comme l’exploration d’un espace littéraire qui est aussi un ‘ailleurs’ intérieur ou extérieur dans lequel le sujet affronte sa propre mort.1937, sechs Jahre vor ihrem Tod in Auschwitz, schrieb Gertrud Kolmar einen aus 17 Gedichten bestehenden, Welten betitelten Zyklus. Die Mehrzahl dieser imaginären Landschaften, in denen nicht explizit auf die NS-Verfolgungen verwiesen wird, befindet sich in einem zugleich räumlichen und zeitlichen, westlichen und östlichen, inneren und äußeren ‘Anderswo’. Kann man aber sagen, Kolmar würde in unwirkliche erdichtete Welten flüchten ? Zwar wird das lyrische Ich gern als ein schaffendes dargestellt, das dann in den von ihm geschaffenen Raum eintritt ; dieser Raum ist jedoch durch Melancholie bzw. Angst geprägt, so dass sich oft ein zweiter Raum eröffnet, der aber wiederum nicht weniger zweideutig ist. Man steht sozusagen vor dem ‘Anderen der Utopie’, das seinen Schatten auf die primär erfundene Landschaft wirft. Die imaginären, ineinander verschachtelten Räume mit ihrer erstarrten und menschenleeren Schönheit können zwar auf das reine Sein hindeuten, sie werden aber auch mit dem Tod oder dem Verschwinden des Subjekts verbunden. Schreiben erweist sich demnach nicht als bloße Flucht vor dem Zeitgeschehen, sondern als Erkundung eines inneren bzw. äußeren ‘Anderswo’, in dem das Subjekt sich seinem Tod stellt.In 1937, six years before her death in Auschwitz, Gertrud Kolmar wrote in Berlin a cycle of 17 poems, untitled Worlds (Welten). These imaginary universes in which no explicit reference to Nazi persecution can be found, are located for most of them in a “distance” meanwhile spatial and temporal, western and “eastern”, inner and outer. It is necessarily possible to say that Kolmar 'shelters' in an unreal universe of literary creation? If the subject likes presenting itself as entering in the very space he has built, this space is yet marked par melancholia or anxiety; so that a second space, “an elsewhere of an elsewhere”, not less ambiguous, often open. We are in a way, in presence of an “Other” of utopia that comes or cast a shadow on the place firstly built. The imagined worlds, with stone beauty but deserted by human beings, can indeed make a sign to the pure Being but are also associated with death and loss of the subject. The writing appears not as a simple conduct of escape before the contemporary events but as the exploration of a literary space that is also an inner or outer “elsewhere” where the subject faces his own death

O Direito Autoral Apreendido Pela Citação / Uma Outra História Do Século XX

Em seu saboroso artigo intitulado Plágio por antecipação (2009), Pierre Bayard faz do anacronismo um método de análise da literatura ou da arte (Fra Angelico plagiou a técnica desenvolvida alguns séculos depois por Jackson Pollock, Sófocles copiou Freud, Voltaire copiou Conan Doyle e Kafka copiou Beckett) para estabelecer ressonâncias entre os textos a partir da figura do plágio. Delito que repousa sobre um empréstimo de uma ideia ou de um texto sem o conhecimento de seu autor, o plágio sinaliza tanto uma semelhança entre duas entidades quanto uma sutil diferença que indica que o texto de empréstimo não pertence ao contexto no qual aparece. Pierre Bayard opta por evidenciar essa dissonância ao tratar do plágio por antecipação, indicando uma problemática estética fundamental: o empréstimo, a citação, o jogo de referências comprovadas. Haveria, de certa forma, autores que se inspirariam em obras posteriores. Palavras-chave: Direito autoral, plágio, citaçã

Le discours identitaire d’extrême droite: révélateur d’une idéologie aux marges du paysage politique?

In his book Histoire de l’extrême droite en France (A history of the extreme right in France), the French historian Michel Winock shows how difficult it is to give a simple, accurate definition of the extreme right, which he presents as ‘a hard political tendency but a soft concept’. However, one of the characteristics which are common to most extreme right-wing parties is that they tend to inscribe their discourse on identity (not only from a political point of view but also from a cultural or even biological point of view) inside a marginal space and even a space of marginality, a domain for marginal personalities.We shall see that those organisations choose to place themselves deliberately into the margins of the political landscape and that they do it in both senses of the term: first because their discourses sound scandalous to democratic parties and secondly because those speeches often reflect their will to exclude themselves from the political game. Indeed, extreme right-wing theorists and politicians frequently refuse to exercise power because they consider that such an activity is almost inevitably tainted with compromise and corruption. So they prefer resorting to verbal – or even physical – violence in order to attract voters eager to protest against the supposed unfairness of the establishment. That is why extreme right-wing factions have to face a difficult situation in which they need to be marginal and scandalous to exist, but in which democratic, governmental parties can easily use their marginal character to turn them into political scarecrows and ensure their own dominance in an even surer way
