La « modestie » de Jugurtha
Authors: Josserand Charles
Published: March 2014

Pour caractériser la docilité calculée de Jugurtha au sein de l'armée romaine assiégeant Numance sous le commandement de Scipion, Salluste écrit modestissume pa rendo. Si l'on considère les propositions de Cicerón touchant le sens de modestia et si l'on relit, d'autre part, le portrait de Scipion dessiné par Polybe, on est amené à voir, dans le texte de Salluste, un reflet de εὐταξία stoïcienne. Dès lors, par modestissume pa rendo, il conviendrait d'entendre « en obéissant avec un sens aigu de l'opportunité ».
Le symbolisme funéraire de la chouette
Authors: Laffineur Robert
Published: March 2014

La présence de petites figures de chouette en or dans le mobilier des tombes mycéniennes (Kakovatos, Ano Englianos, Peristeria) est liée au symbolisme funéraire qui était attaché à l'oiseau de nuit dans l'antiquité, en particulier à son rôle apotropaïque. Les allusions à ce symbolisme chez les auteurs anciens permettent d'en préciser la nature. Les documents archéologiques postérieurs confirment par ailleurs l'interprétation proposée.

Persuasion et violence chez Platon
Authors: Motte André
Published: March 2014

La présence continue, dans les Dialogues, du couple peithô-bia fait écho à l'important débat, moral et politique, qui mit aux prises divers penseurs du Ve siècle. Pour le clarifier, Platon étend la problématique aux domaines de la psychologie et de la métaphysique. S'il opte résolument pour une éthique de la juste persuasion, fondée sur la recherche du vrai, et s'est efforcé d'y conformer sa conduite, certaines de ses conceptions politiques, en raison de l'idéalisme qui les inspire, restent, sous ce rapport, fort équivoques.
Sur la Domestica seditio de Justin (XXVII 1 9)
Authors: Peremans Willy
Published: March 2014

Le texte de Justin (XXVII, 1, 9), qui mentionne une domestica seditio en Egypte au début du règne de Ptolémée III, continue à attirer l'attention des historiens. Rapprochant le P. Haun. 6 (ed. T. Larsen, Copenhague, 1942, pp. 37-43) du passage de Justin, W. Huss [Aegyptus, 58 (1978), pp. 151-156] défend la thèse que les Égyptiens, poussés par un sentiment antihellène, se sont révoltés contre Ptolémée III en 245 av. J.-C. Sans vouloir prétendre que l'élément national soit complètement absent dans la conduite des Égyptiens, l'auteur du présent article est cependant d'avis que la seditio dont parle Justin a été plus sociale que nationale.
La langue homérique et le rayonnement littéraire de l'Eubée
Authors: Wathelet Paul
Published: March 2014

Dans l'ensemble, la langue épique atteste le troisième allongement compensatoire, les formes avec allongement étant susceptibles d'en recouvrir de plus anciennes, qui maintiendraient les groupes dont la disparition entraîne l'allongement. Il y a toutefois quelques exceptions, qui ne sont pas d'emploi formulaire et pourraient résulter de l'influence de l'ionien occidental sur la tradition épique. Il en va de même pour les quelques rares cas de correptio attica. On rapprochera ces faits de l'importance que semblent avoir eue l'Eubée et surtout Chalcis au VIIIe s.
Nouvelles orientations dans l'étude de l'arrhéphorie attique
Authors: Van Sichelen Laurence
Published: March 2014

Cette étude, qui repose sur les sources littéraires et lexicographiques, s'oriente vers trois centres d'intérêt : en premier heu, le problème de topographie soulevé par une phrase de Pausanias (I, 27, 3) ; ensuite, une brève révision de la tradition relative à la durée et au calendrier de l'arrhéphorie ; enfin, une remise en question de la signification religieuse du terme « arrhéphorie », fondée sur l'analyse étymologique.

L'illusionnisme spatial dans la peinture grecque des VIIe et VIe siècles. Essai de typologie
Authors: Martens Didier
Published: March 2014

Les peintres attiques sur support céramique essayèrent dès le VIIe siècle de remédier aux limitations inhérentes à l'usage de pictogrammes plans de forme standardisée en tentant d'intégrer à l'image le volume convexe du vase. Cette absorption plus ou moins importante du support dans la représentation donne lieu à des perceptions de nature illusionniste, l'image acquérant un caractère de réalité inattendu. Sur de nombreuses pièces d'époque archaïque, on peut ainsi constater que le galbe de la panse apporte aux figures peintes le volume qui leur fait défaut par rapport à leurs prototypes naturels, tandis que le plan horizontal formé par l'épaule tend à devenir le lieu même de l'action représentée.
Poseidon and the Tuna
Authors: Shapiro H. A.
Published: March 2014

Une des peintures les plus fameuses de la Grèce archaïque, connue seulement par une description que l'on trouve chez Athénée (VIII, 346 b-c), représentait Zeus juste avant la naissance d'Athéna, ainsi que son frère en train de lui offrir un thon. L'article propose d'identifier le même sujet sur une amphore à figures noires du peintre Affecter, conservée à Harvard University. La popularité de la Naissance d'Athéna, de Poséidon et de son thon sur des vases s'expliquerait par référence au tyran Pisistrate, protégé d'Athéna et descendant de Poséidon, qui, en 546, au moment de son retour à Athènes, reçut un oracle où il était question de ce poisson.
The Ceremony of the Helots in Thucydides IV 80
Authors: Jordan Borimir
Published: March 2014

L'A. propose une explication d'un curieux texte de Thucydide qui rapporte l'extermination de 2000 hilotes par les Spartiates. Après les avoir libérés, ils leur avaient donné la permission de faire le tour des sanctuaires de Sparte avec des couronnes ; après quoi, ils les tuèrent. Liant les événements, comme le fait Thucydide, l'A. défend l'idée que les Spartiates ne laissèrent les hilotes accomplir le rite que pour obtenir un prétexte à leur action homicide : une telle cérémonie étant la prérogative des membres de la Gérousia, les imiter constituait une grave offense, digne de la peine de mort.
Delphinion ou Daphnéphoreion ?
Authors: Loucas Ioannis , Loucas-Durie Eveline
Published: March 2014

En 1982, Cl. Bérard, dans les Hommages à H. Metzger, rapportait la scène en question à l'expulsion du pharmakos. Il la localisait devant un sanctuaire apollinien, qui serait le Delphinion d'Athènes, écartant sans explication l'éventualité plus probable d'un daphnéphoreion, qu'il avait proposée auparavant [dans Ant. Kunst, 14 (1971)]. Cependant, un réexamen d'ATHËNÉE, X, 424 e-f, que Cl. Bérard ne paraît pas avoir alors exploité en profondeur, invite les A. à défendre l'idée qu'il s'agit d'un daphnéphoreion, celui de Phlya en Attique.
Matière et signification. Rituel, sexe et pharmacologie dans le corpus hippocratique
Authors: von Staden Heinrich
Published: March 2014

Les relations entre la matière médicale utilisée à l'époque classique et le sens dont la matière est porteuse peuvent se préciser si l'on analyse les rapports entre la valeur accordée, par les auteurs hippocratiques, aux ingrédients particuliers (par exemple, aux excréments animaux, au soufre, à l'asphalte et à la seule) et leur valorisation dans les cultes. C'est ainsi que la réservation hippocratique de la prescription des excréments au traitement des femmes peut être éclaircie au moyen des lois sacrées grecques.
Nietzsche e le Baccanti di Euripide
Authors: Bonelli Guido
Published: March 2014

Nietzsche a ses idées à lui sur la naissance et sur le développement de la tragédie : c'est pourquoi il escamote sa dette envers les Bacchantes d'Euripide, en qui il voit un poète tardif dépourvu d'esprit tragique. Ce qui lui manque, selon Nietzsche, c'est précisément la puissance dionysiaque. Cependant, le dionysiaque est le même dans les Bacchantes et dans la Naissance de la tragédie : il s'agit d'un acte de libération de nos énergies primordiales, chargé d'ambivalence entre la joie et la douleur.
Platon peintre des âges de la vie humaine (République VIII 544 a - IX 580 c)
Authors: Meulder Marcel
Published: March 2014

Au livre VIII de la République de Platon, le timocrate se comporte en guerrier d'âge mûr, l'oligarque en vieillard, le démocrate en jeune adulte, le tyran en enfant et en adolescent. Héritière de la tradition, cette peinture des âges annonce celle de la Rhétorique d'Aristote. D'autre part, les séquences timocrate-oligarque et démocrate-tyran annoncent les deux mouvements décrits dans le Politique (270 b - 273 a), l'une celui qu'impriment les dieux, l'autre celui qui est abandonné de ces derniers et oublieux de leurs instructions.

Platón: la transición a la ciudad ideal
Authors: Solana Dueso José
Published: March 2014

Plato: the transition to the ideal city.

This paper analyses two related issues. Firstly, we ask whether the platonic proposal for the ideal city is merely a theoretical one, as many scholars maintain, or whether it must be understood in a practical sense. The article argues in favour of the second possibility. Secondly, assuming the Platonic postulate of an union between philosophy and political power, the paper searches for a model of transition to the perfect city, which would consist of a government of centralized power, formed by a virtuous tyrant associated with a good legislator (philosopher). In this way, the linear process of political degradation, which is described in Book 8 of the Republic, would have to be understood as a cyclical process. This is suggested by some Platonic remarks and is explicitly asserted by an Aristotelian text in Politics.

Allopatric diversification, multiple habitat shifts, and hybridization in the evolution of Pericallis (Asteraceae), a Macaronesian endemic genus
Authors: Jones Katy E. , Reyes‐Betancort J. Alfredo , Hiscock Simon J. , Carine Mark A.
Published: March 2014

• Premise of the study: Geographic isolation, habitat shifts, and hybridization have contributed to the diversification of oceanic island floras. We investigated the contribution of these processes to the diversification of Pericallis, a genus endemic to Macaronesia.

• Methods: Data from the chloroplast psaI‐accD and trnV‐ndhC regions and the nuclear ribosomal internal transcribed spacer region (ITS) were sampled for multiple accessions of all taxa and used to establish phylogenetic hypotheses. Habitat preferences were optimized to investigate habitat shifts, and divergence times were estimated. Species nonmonophyly was investigated using Bayes factors.

• Key results: Much of the diversification in Pericallis has occurred recently, within the past 1.7 Ma. Three habitat shifts have occurred in the evolution of the genus. However, geographic isolation has played a greater role in its diversification. Novel allopatric patterns were revealed within some species, highlighting the significance of geographic isolation in the evolution of Pericallis. One species (P. appendiculata) that resolved as monophyletic in the ITS analysis was polyphyletic in the chloroplast analysis. Bayes factors provide strong support for the nonmonophyly of P. appendiculata haplotypes, and their phylogenetic placement suggests that ancient hybridization is responsible for the haplotype diversity observed.

• Conclusions: Multiple markers and extensive sampling provided new insights into the evolution of Pericallis. In contrast to previous studies, our results reveal a more significant role for allopatry than habitat shifts and new evidence for ancient hybridization in the evolution of Pericallis. Our study highlights the power of broad taxon sampling for unraveling diversity patterns and processes within oceanic island radiations.
Les conditions de la résilience des services urbains parisiens par l’apprentissage collectif autour des interdépendances
Authors: Toubin Marie , Diab Youssef , Laganier Richard , Serre Damien
Published: March 2014

Si le concept de résilience, avec ses notions d’absorption, d’adaptation et d’apprentissage à l’occasion d’une perturbation, semble prometteur pour la gestion des villes exposées aux risques, il manque aujourd’hui d’opérationnalité. Notre recherche vise alors, non pas à définir ou évaluer les caractéristiques de la résilience urbaine, mais à construire une démarche collaborative visant à développer une connaissance partagée et améliorer la coordination entre gestionnaires de la ville. En particulier, notre travail porte sur les services urbains qui ont montré leur importance dans la propagation des perturbations et dans le maintien et le rétablissement des fonctions urbaines pendant et après une crise. Sur la base de données collectée lors d’entretiens avec les gestionnaires des services urbains parisiens, des ateliers collaboratifs ont été organisés avec l’appui de la Ville de Paris. Ils ont permis d’améliorer la connaissance commune des interdépendances des services urbains puis de modéliser les stratégies mises en place par chaque service dans le cadre de leur préparation au risque de crue centennale. L’analyse de ces résultats montre la complexité de la situation de la métropole francilienne face au risque d’inondation et le besoin d’une gestion intégrée des grands services urbains : transports, énergie, eau, déchets, télécommunications. L’approche collaborative répond alors au besoin de communication et de coordination exprimé par ces acteurs fortement interdépendants et favorise l’élaboration de solution intégrée et contribuant à la résilience de la ville.

Published: March 2014

In this paper, we present a method to estimate the [α/Fe ]using the spectra from ninth data release of Sloan Digital Sky Survey (SDSS). We first use principal component analysis (PCA) to reduce the dimension of the spectra, and then use Gaussian process regression (GPR) to estimate the [α/Fe ]ratios. The results show that GPR is accurate and efficient in estimating the [α/Fe]ratios. Further analysis shows that using PCA can improve the estimation accuracy of GPR.

Published: March 2014

Considering the fuzzy reasoning can be distributed over every node of a pervasive computing environment, we propose a fuzzy reasoning Petri net model with load detection (LD-FRPN) towards the decomposition of distributed fuzzy reasoning in this paper. The LD-FRPN model applies a hierarchical structure to make a description of reasoning on nodes more clear. We divide transitions of LD-FRPN into three classes to describe the reasoning, migrating and integrating of contexts respectively. With these transitions, the distributed reasoning of the pervasive computing environment will be specified.

An Algorithm for Mesh Simplification Based on Energy-Aware
Authors: Liu Fu Yan , Fan Chong Yuan
Published: March 2014

Mesh simplification should not only emphasize high compression ratio, but also maximize retention of a mesh representation which is another objective of mesh compression. In one of our 3D projects, in order to pursue the optimization model display, we proposed a new mesh simplification algorithm. This article describes the algorithm based on energy-aware which used to simplify a mesh of 3D model. Our approach has two major contributions. Firstly, we used an optimization method based on energy-aware, which seeks to collect low energy value vertexes of a mesh. Vertex energy is calculated by an energy function that describes the potential energy between the vertex and its directly related vertexes in a space. Secondly, our optimization method transforms a mesh into a series of triangle stripes, and reduces low energy vertexes of those stripes effectively. The process of compression is simple, efficient and adjustable for users. From the result of experiments, we can learn that our algorithm is suitable for processing several kinds of grid, and retains the characterization from original mesh very well. Our approach solved the problem of obvious distortions of a simplified mesh of 3D model, and significantly improved the efficiency of simplification process.

in the field of artificial intelligence, Case Based Reasoning (CBR) is an arising reasoning technique, in which choosing reasoning index has been the hot topic and difficulty. In order to get optimal feature subset in the process of index selection, this paper combined gray correlation analysis with genetic algorithm (GA) to optimize the feature selection process, taking the gray correlation analysis result as the initial population for GA heuristic search, which can on one hand get better feature combination, on the other hand, effectively reduce the evolution of GA, finally improving GAs execution efficiency. Based on this, an optimized GA-CBR case reasoning model is put forward, which has been proved by empirical results to have an improved CBR forecasting accuracy.
