We are in 1563, somewhere on a Brazilian beach about 100 kilometres north of what is now São Paulo. A young man in a cowled robe alone on the beach is writing a poem on the sand with the point of his stick. The hostage of a savage tribe for weeks, he struggles daily against manifold carnal temptations, personified in the voluptuous native women who come to visit him every evening in his hammock, and addresses his Latin verses to the (...) Virgin Mary in order to fortify his virtue. The threat of being killed and eaten by cannibals is nothing to him by comparison with the loss of his virginity. Recourse to his own original culture is the ultimate bulwark against contamination, the sign of resistance and strengthening of his identity. The definitive rejection of the Other is, in these circumstances, a survival reflex. (shrink)

Fragments of painted plaster found in the destruction layer of three first floor rooms in the House of Seals and of one first floor room of the House of the Sword had broken from the ceiling. They allow the restoration of the schema in the room of the House of the Sword and of two of the rooms in the House of Seals, the latter in colour. Composed of bands surrounding a quadrangular field, these décorations, evoking carpets stretched on the (...) ceiling, are richer (costly pigments, gold leaf) and more complex (some fifteen motifs) than those in tombs of the same period, which adopted the same « carpet » composition and which borrowed from the same repertoire, often confirmed by the textiles. Since we know of no other ceiling decoration in habitation rooms, it is unwise to contrast the exuberance of these ceilings with the tomb ceilings. The room that could not be restored had moreover a much more perfunctory decoration. (shrink)

Tri‐methylation of lysine 4 on histone H3 (H3K4me3) is a near‐universal chromatin modification at the transcription start site of active genes in eukaryotes from yeast to man and its levels reflect the amount of transcription. Because of this association, H3K4me3 is often described as an ‘activating’ histone modification and assumed to have an instructive role in the transcription of genes, but the field is lacking a conserved mechanism to support this view. The overwhelming finding from genome‐wide studies is that actually (...) very little transcription changes upon removal of most H3K4me3 under steady‐state or dynamically changing conditions, including at mammalian CpG island promoters. Instead, rather than a major role in instructing transcription, time‐resolved experiments provide more evidence supporting the deposition of H3K4me3 into chromatin as a result of transcription, influencing processes such as memory of previous states, transcriptional consistency between cells in a population and transcription termination. -/- .

Le transport aérien du courrier, en d'autres termes la poste aérienne, est moins une innovation technique qu'organisationnelle. Avec elle, il ne s'agit pas, seulement, de faire voler des avions, mais de les insérer dans un système complexe de collecte, de transport et de distribution de courrier à travers des territoires. L'exploit du vol en lui-même ne suffit pas, il doit aussi être régulier et sûr, et en somme s'articuler au mieux au reste de la chaîne postale pour satisfaire les usagers. (...) Seule une coopération, au sens strict une opération en commun du réseau par les acteurs concernés, le permet: les offices postaux d'une part et les compagnies aériennes d'autre part ont à travailler en étroite relation, et donc à communiquer. Dans les années 1920, la genèse de la poste aérienne se fait à travers la construction d'un espace de sens commun, mêlant institutions et signes. Une infrastructure de papier finit par porter les avions.Air transportation of mail, in other words airmail is less a technical innovation organizational. With it, it is not only to fly planes, but inserting them into a complex system of collection, transport and delivery of mail across territories. The feat of flying itself is not enough, it must also be smooth and safe, and in fact is the best articulate the rest of the mail stream to satisfy users. Only cooperation in the strict sense a joint operation of the network by stakeholders, allows: post offices on the one hand and the other airlines have to work closely, and thus communicate. In the 1920s, the genesis of airmail is done through the construction of a space of common sense, combining institutions and signs. Infrastructure eventually wear paper airplanes. (shrink)

Début 1871, Helmholtz donne une conférence à Heidelberg, devant un public de non spécialistes, sur « la genèse du système planétaire », dont le sujet sera ce qu’il appelle la théorie de Kant-Laplace. Plutôt que de commencer par expliquer ce qu’il faut entendre par cette dernière, Helmholtz expose devant ses auditeurs la représentation que l’on se fait désormais de la formation des corps célestes et de leur devenir probable, en s’appuyant sur les progrès des connaissances, la découverte de nouvelles lois, (...) l’usage d’instruments de plus en plus perfectionnés. C’est ainsi que la validité de l’hypothèse de Kant et de Laplace se trouve confirmée a posteriori et leur audace légitimée. Aussi, la démarche adoptée par Helmholtz relativise-t-elle implicitement, et peut-être à son insu, la rigueur postulée de la bonne méthode scientifique. La cosmogonie esquissée par Helmholtz ressemble à un spectacle bien étudié dont les auditeurs sont les spectateurs, les savants, les acteurs, et la science épurée, l’enjeu. L’analyse de ce texte a donc pour objectif principal d’identifier et de rappeler les éléments contextuels qui lui confèrent son épaisseur, depuis la guerre franco-prussienne jusqu’aux tensions idéologiques, philosophiques, scientifiques qui en sont l’arrière-plan.

À partir de l'étude de la constitution et de l'histoire des archives du parlement de Paris et de leur traitement archivistique, ainsi que des multiples collections de copies et d'extraits dont elles ont été l'objet, cet article propose une réflexion sur la manière dont ce fonds d'archives, qui allie une exceptionnelle importance matérielle et historique et une particulière complexité, a pu être traité par les archivistes et utilisé par les chercheurs, ainsi que sur les perspectives qu'il peut ouvrir à la (...) recherche. Ces archives du Parlement illustrent en effet toute la gamme des problèmes de conservation, de traitement, de communication au public et d'exploitation et rendent particulièrement manifeste la complémentarité et l'interpénétration nécessaires, voire la confusion, des approches historique et archivistique ; elles démontrent que la connaissance par les chercheurs de l'histoire du fonds d'archives va bien au-delà de la simple pratique archivistique et contribue à la perception de la documentation comme« source» d'histoire.

Abstract Recently, there has been a growing interest in public health and public health ethics. Much of this interest has been tied to efforts to draw up national and international plans to deal with a global pandemic. It is common for these plans to state the importance of drawing upon a well-developed (...) ethics framework and we argue that this framework should reflect the values and insights of feminist relational theory. More specifically, we argue that pandemic planning must be squarely situated in the larger realm of public health and that an ethics framework for public health will be one that recognizes the need to pay particular attention to the vulnerability of subpopulations lacking in social and economic power. We propose an ethics framework for public health that builds on the notions of relational personhood (including relational autonomy and social justice) and relational solidarity. In this way, we aim for a public health ethics that, as appropriate, promotes the public interest and the common good. CiteULike Connotea Del.icio.us What's this? (shrink)

En partant de la définition des rituels, et notamment du rôle de la parole, qu'elle soit verbale ou non-verbale, cet article interroge la façon dont la ritualisation peut contribuer à l'éducation, notamment en milieu scolaire. Après un tour d'horizon des principaux aspects rituels de l'enseignement et de l'école, l'auteur questionne plus particulièrement les rituels d'apprentissage, c'est-à-dire ceux qui structurent la relation enseignant/enseigné au sein de la classe. En s'appuyant sur une théorisation psychanalytique elle montre alors comment les rituels peuvent ou (...) non, notamment en fonction de leur degré « d'ouverture », contribuer à faire exister les élèves dans leur singularité et, ce faisant, les aider à se construire dans leur rapport au savoir.Starting from the definition of rituals, including the role of speech, either verbal or non-verbal, this article examines how ritual can contribute to education, particularly in schools. After an overview of the main aspects of teaching and rituals of the school, especially the author questions the rituals of learning, that is to say those that structure the relationship teacher / learner in the class. Based on psychoanalytic theorizing it then shows how rituals may or may not, depending on their particular degree of "openness" to help students exist in their singularity, thereby helping to build in their relation to knowledge.

Suddenly, COVID-19 has changed the world and the way people work. Companies had to accelerate something they knew was imminent in the future, but not immediate and extremely humongous. This situation poses a huge challenge for companies to survive and thrive in this complex business environment and for employees, who must adapt to this new way of working. An effective e-leadership, which promotes companies’ adaptability, is needed. This study investigates the existing knowledge on teleworking and e-leadership; and analyzes the supposed (...) challenges. The literature review shows that companies with effective e-leadership can view teleworking as an opportunity. It is advantageous for not only companies’ productivity but also the environment and people who work remotely. However, a traditional or no leadership can result in some risks. Thriving in remote work environments implies that managers must adjust the companies’ structure, making them less hierarchical, and developing new abilities to establish a strong and trustworthy relationship with their employees to maintain their competitiveness, while retaining a genuine concern for their employees’ well-being. Similarly, successful e-leadership must be able to consolidate and lead effective virtual teams to accomplish organizational goals. This study contributes to the literature and leaders during the pandemic. (shrink)

Les premières mythographies de l’Europe néo-latine, depuis la Genealogia deorum de Boccace, considèrent l’histoire des dieux sur le modèle des généalogies humaines, en cherchant à recomposer « la lignée de Saturne ». Les premiers historiens de la Grèce, comme les poètes, inventèrent des généalogies mythiques pour inscrire l’origine des hommes dans l’histoire de leur relation aux dieux. Que fondent les généalogies divines ? Non seulement des structures religieuses, non seulement la raison même des sociétés humaines, mais encore la préhistoire de (...) l’humanité. Mais si les engendrements divins donnent sens aux relations entre les hommes et les dieux, c’est l’histoire des commencements du monde que les mythographes cherchent à comprendre en interrogeant l’articulation des généalogies divines et humaines. Depuis que, dans le Timée, Platon a associé mythologia et genealogia comme deux modes de discours « archéologiques », les mythographes ont ouvertement revendiqué un savoir sur le monde qui se définit comme une synthèse des « sciences de la nature ».Mythologia, Genealogia, Archaiologia:A Paleontological Scope for Mythography. The first European mythographical treatises in the Middle Ages and Renaissance, since Boccaccio’s Genealogia deorum, were determined by a genealogical method, looking at the history of the gods with human patterns and seeking the reconstruction of “Saturn’s lineage”. The early Greek mythographers, like the poets, imagined various genealogies for seeking out the origins of humanity through their relationships with gods. What is founded on divine genealogies? Not only religious structures, nor only the true ratio of human sociability, but a human paleon­tology too. By interpreting filiations as a system of connexions between gods and humans, the mythographers aimed at understanding the protohistory of the universe. Since Plato’s Timaeus associated mythologia and genealogia as two modes of “archaeological” discourse, mythographers have wanted to assert their own “physical science” as a whole synthetic perception of the natural world.

A totally ordered group G is essentially periodic if for every definable non-trivial convex subgroup H of G every definable subset of G is equal to a finite union of cosets of subgroups of G on some interval containing an end segment of H; it is coset-minimal if all definable subsets are equal to a finite union of cosets, intersected with intervals. We study definable sets and functions in such groups, and relate them to the quasi-o-minimal groups introduced in Belegradek (...) et al. . Main results: An essentially periodic group G is abelian; if G is discrete, then definable functions in one variable are ultimately piecewise linear. A group such that every model elementarily equivalent to it is coset-minimal is quasi-o-minimal , and its definable functions in one variable are piecewise linear. (shrink)

Given a simple non-trivial finite-dimensional Lie algebra L, fields $K_i$ and Chevalley groups $L(K_i)$ , we first prove that $\Pi_{\mathcal{U}} L(K_i)$ is isomorphic to $L(\Pi_{\mathcal{U}}K_i)$ . Then we consider the case of Chevalley groups of twisted type ${}^n\!L$ . We obtain a result analogous to the previous one. Given perfect fields $K_i$ having the property that any element is either a square or the opposite of a square and Chevalley groups ${}^n\!L(K_i)$ , then $\pu{}^n\!L(K_i)$ is isomorphic to ${}^n\!L(\pu K_i)$ . (...) We apply our results to prove the decidability of the set of sentences true in almost all finite groups of the form L(K) where K is a finite field and L a fixed untwisted Chevalley type.

We need to distinguish two sorts of natural kinds, scientific and common NKs, because the notion of NK, which has to satisfy demands at three different levels—ontological, semantic and epistemological—, is subject to two incompatible sets of constraints. In order to prove this, I focus on the much-discussed case of jade. In the first part of the paper, I show that the current accounts are unsatisfactory because they are inconsistent. In the process, I explain why LaPorte’s analysis of “jade” as (...) a vernacular NK-term with an open-texture meaning does not offer a way out. Using a reductio ad absurdum argument, I conclude that according to the main tenets of NK-term theories, today’s “jade” has to be an NK-term, and jade thereby an NK. In the second part of the paper, I argue for this conclusion in a positive manner. First, I present a series of thought experiments demonstrating that today’s “jade” has the specific features of an NK-term. Then, I show that the kind that we presently call “jade” exhibits the typical ontological and epistemological features of an NK. More generally, I expound on why common NKs are more than mere classes, and why categories such as “jade” are useful in many inferences and explanations. (shrink)

We study extensions of Presburger arithmetic with a unary predicate R and we show that under certain conditions on R, R is sparse and the theory of $\langle\mathbb{N}, +, R\rangle$ is decidable. We axiomatize this theory and we show that in a reasonable language, it admits quantifier elimination. We obtain similar results for the structure $\langle\mathbb{Q},+, R\rangle$.

Given a model-complete theory of topological fields, we considered its generic differential expansions and under a certain hypothesis of largeness, we axiomatised the class of existentially closed ones. Here we show that a density result for definable types over definably closed subsets in such differential topological fields. Then we show two transfer results, one on the VC-density and the other one, on the combinatorial property NTP2.

In this article, I argue that there is no compelling therapeutic ‘need’ for human nuclear genome transfer to prevent mitochondrial diseases caused by mtDNA mutations. At most there is a strong interest in this technology on the part of some women and couples at risk of having children with mitochondrial disease, and perhaps also a ‘want’ on the part of some researchers who see the technology as a useful precedent – one that provides them with ‘a quiet way station’ in (...) which to refine the micromanipulations techniques essential for other human germline interventions and human cloning. In advance of this argument, I review basic information about mitochondrial disease and novel genetic strategies to prevent the transmission of mutated mitochondria. Next, I address common features of contemporary debates and discussions about so-called mitochondrial replacement. First, I contest the cliché that science-and-technology is fast outpacing ethics. Second, I dispute the accuracy of the term ‘mitochondrial replacement’. Third, I provide a sustained critique of the purported ‘need’ for genetically-related children. In closing, I call into question the mainly liberal defense of human nuclear genome transfer. I suggest an alternative frame of reference that pays particular attention to issues of social justice. I conclude that our limited resources should be carefully expended in pursuit of the common good, which does not include pandering to acquired desires. (shrink)
