Sponges are important but often‐neglected organisms. The absence of classical animal traits (nerves, digestive tract, and muscles) makes sponges challenging for non‐specialists to work with and has delayed getting high quality genomic data compared to other invertebrates. Yet analyses of sponge genomes and transcriptomes currently available have radically changed our understanding of animal evolution. Sponges are of prime evolutionary importance as one of the best candidates to form the sister group of all other animals, and genomic data are essential to (...) understand the mechanisms that control animal evolution and diversity. Here we review the most significant outcomes of current genomic and transcriptomic analyses of sponges, and discuss limitations and future directions of sponge transcriptomic and genomic studies.

Sponges branch basally in the metazoan phylogenetic tree and are believed to be composed of four distinct lineages with still uncertain relationships. Indeed, some molecular studies propose that Homoscleromorpha may be a fourth Sponge lineage, distinct from Demospongiae in which they were traditionally classified. They harbour many features that distinguish them from other sponges and are more evocative of those of the eumetazoans. They are notably the only sponges to possess a basement membrane with collagen IV and specialized cell‐junctions, thus (...) possessing true epithelia. Among Homoscleromorphs, we have chosen Oscarella lobularis as a model species. This common and easily accessible sponge is characterized by relatively simple histology and cell composition, absence of skeleton, and strongly pronounced epithelial structure. In this review, we explore the specific features that make O. lobularis a promising homoscleromorph sponge model for evolutionary and developmental researches. (shrink)

Les théories de l'Institution: essai d'ontologie juridique / Georges Renard Date de l'édition originale: 1930 Le présent ouvrage s'inscrit dans une politique de conservation patrimoniale des ouvrages de la littérature Française mise en place avec la BNF. HACHETTE LIVRE et la BNF proposent ainsi un catalogue de titres indisponibles, la BNF ayant numérisé ces oeuvres et HACHETTE LIVRE les imprimant à la demande. Certains de ces ouvrages reflètent des courants de pensée caractéristiques de leur époque, mais qui seraient aujourd'hui (...) jugés condamnables. Ils n'en appartiennent pas moins à l'histoire des idées en France et sont susceptibles de présenter un intérêt scientifique ou historique. Le sens de notre démarche éditoriale consiste ainsi à permettre l'accès à ces oeuvres sans pour autant que nous en cautionnions en aucune façon le contenu.

A typology of rumours is constructed according to their relation to reality after their veracity has been authenticated. True rumours become information. Untrue rumours are categorized as affirming or denying rumours; affirming rumours state the reality of imaginary facts, whereas denying rumours undermine the reality of established facts. Denying rumour types are distinguished and discussed under rubrics of alleged survival, doubles, bogus events and so on, and through their characteristic features of hypercritical thinking, hidden reality revelation and plot denunciation. In (...) a world where knowledge is no longer seen as objective or final, where the public have become suspicious of governments and the media, and where real and synthetic images are often indistinguishable, denying rumours and ideas are expected to feature more significantly on the information market, as already typified by activity on the web.

Since the beginning of the new millennium, initiatives known as roundtables have been developed to create voluntary sustainability standards for agricultural commodities. Intended to be private and voluntary in nature, these initiatives claim their legitimacy from their ability to ensure the participation of all categories of stakeholders in horizontal participatory and inclusive processes. This article characterizes the political and material instruments employed as the means of formulating agreement and taking a variety of voices into consideration in these arenas. Referring to (...) the specific case of the “Roundtable on Sustainable Palm Oil”, I undertake a detailed analysis of the tensions relating to different forms of participation, which create a gap between “local minority voices” and international stakeholders—either non-governmental organizations or industries. Local communities and small-scale farmers face difficulties when making their voices heard in the form of debate proposed. Firstly, some participants attempt to re-impose a vertical hierarchical relationship between small-scale farmers or affected communities and company managers/directors in order to deprive the former of their powers of representation and of being able to transform reality. Secondly, the liberalism of interest groups in the roundtable accords value to experts, global knowledge, strategy, and detachment, at the expense of other capabilities of rooted or attached people who come to defend their real lives with a desire to raise critical issues of injustice. In this context, I highlight the capacity of local NGOs to relieve some of those tensions and to help locally affected communities and small-scale farmers introduce public stages for debates, by accommodating other forms of participation apart from the liberal one. By being close to and by restoring their dignity through a specific work of solicitude and care, local NGOs prepare affected people for public speaking. (shrink)

At first approach the use of the word “superstition” is such that it is impossible to apply the term strictly in the human sciences. Its connotation, that is its content, is particularly subjective and negative. And its extension, that is its area of application, is indefinite and makes of it a concept that can refer to just about anything.

With an overwhelming volume of studies on Venice's port architecture and coastal protection, the challenge remains to convey to lay readers how the science of hydraulics was applied. This article reports an experiment in creating a vivid narrative of the movement and effects of sand over a relatively short period of twelve years (1610-1622), which, in this case, started with the fifteen-year-old carcass of a shipwreck at risk of capsizing. I emulate how the erosion of sandbanks triggered by the stranded (...) wreck affected the subsequent silting of the canal. This, in turn, influenced the relationships between land and sea, access and obstruction, and arrivals and departures. Such a microhistory of sand offers a broad picture of the maritime know-how and technology that came into play. Finally, the essay reflects on microhistory's potential to explore port architecture’s technicalities. This approach yields an understanding of the exquisitely practical, in-depth details of the engineering response to significant, contemporary, normal, and catastrophic events. (shrink)

En este texto confluyen logradamente varios géneros literarios: es una autobiografía, porque ante nuestros ojos vemos transcurrir parte de la vida del autor; pero también es un testimonio histórico, porque aborda acontecimientos verídicamente ocurridos en el Chile que existió entre los años 1965 y 1973. Paralelamente, estamos en presencia de un texto político, que aborda la problemática de la lucha de clases y su expresión en cuanto a correlación de fuerzas sociales, políticas y, al menos esb..

The image of the Other, particularly in the Western World, expresses itself through a continuous flow of representations of fabulous peoples with strange physical appearance living in far-away places. In our day, the successors to the sirens, Cyclops, unípedes and cynecephala of Antiquity, the Middle Ages and the Renaissance are the Sirians, Saturnians, Selenites and Martians of the 17th through the 20th centuries.

Le rapprochement entre émancipation féminine et religion peut sembler incongru, car il est généralement admis que les convictions religieuses sont un obstacle au féminisme et à toute forme d'émancipation. Il apparaît toutefois que les idées religieuses de George Sand, issues de différents courants de pensée du romantisme, peuvent servir de point d'appui à l'émancipation féminine. Elles semblent en outre préfigurer certaines découvertes des sciences humaines, de la sociologie historique et de l'ethnologie notamment, qu'avait résumées Bachofen vers 1860 sous le vocable (...) " religions favorables au droit de la mère ". The parallel between emancipation of women and religion could seem incongruous since it is generally accepted that religious convictions are an obstacle to feminism or to any form of emancipation. It would appear however that George Sand's religious ideas, stemming from various thought trends in romanticism, could serve to support women's emancipation. Sand's ideas also prefigure certain discoveries of human sciences, notably historical sociology and ethnology, which Bachofen had summarised around 1860 under the expression " religions favourable to maternal right ".

This article puts forth a theory and history of the experiential moment of romance, traced from Homer’s Odyssey to Jean-Jacques Rousseau. Differing from other forms of the moment that have been bequeathed by Western tradition—such as kairos, conversio, the Aristotelian pair peripeteia and anagnorisis, or the Romantic Augenblick—the experiential moment foregrounds experientiality within a self-enclosed and atelic temporality: a time that goes nowhere. Building on previous theories of epic and romance that see them as conflicting temporal forms, the first part (...) of the article demonstrates how the experiential moment in traditional romance always exists in tension with the temporality of the epic project of the collective. The second part proposes a new reading of Rousseau by showing how his three works, Julie, ou La Nouvelle Héloïse, Les Confessions, and Les Rêveries du promeneur solitaire not only continue this conflict into the modern period but also begin to reverse the old hierarchical relationship between epic and romance or the temporality of the collective and that of the experiencing individual in her individual consciousness. It is argued that Rousseau in his final work the Rêveries strives to liberate the experiential moment from epic temporality altogether and thereby lays the foundation for a wholly new way of approaching the moment in literary modernity.
