Editors of Cicero'sPro Archiahave assumed that Petrarch's lost transcription of the equally lost Liège manuscript that he discovered in 1333 survives in an almost unaltered version in a single Florentine manuscript, while the remaining 265Italireflect another stage of the text, when conjectural corrections by its learned discoverer were introduced into the text. This article proposes a reassessment of that dichotomy, based on a first comprehensive study of the whole transmission.

Selecting a large and diverse sample of 5–6-year-old preschool children, we aimed to extend previous findings on variability in children’s home math environment and its association with children’s mathematical skills. We operationalized mathematics in a broader way than in previous studies, by considering not only children’s numerical skills but also their patterning skills as integral components of early mathematical development. We investigated the effects of children’s gender and socioeconomic status on their home math environment, examined the associations between children’s home (...) math environment and their mathematical skills, and verified whether these associations were moderated by children’s gender and/or SES. Parents of 353 children completed a home math environment questionnaire and all children completed measures of their numerical and patterning skills. Results indicated no effect of children’s gender on their home math environment. There was no effect of SES on the performed home math activities, but small SES differences existed in parents’ math-related expectations and their attitudes. We found no evidence for associations between children’s home math environment and their mathematical skills. Furthermore, there were no moderating effects of gender or SES on these associations. One explanation for these findings might relate to the characteristics of the general preschool system in the country of the present study. Future studies should consider the effect of the preschool learning environment because it might explain differences between studies and countries with regard to the home math environment and its association with mathematical skills.

This article first presents a codicological and paleographical analysis of the Bibliotheca Medicea Laurenziana's manuscript Plut. 57.12, a codex containing the Epistolographi Graeci that was owned and annotated by Francesco Filelfo. The original nucleus of this composite was produced in Constantinople in the third decade of the 15th century. Afterwards, Filelfo himself had two copyists -one of whom is identifiable as Gerard of Patras - transcribe supplements to be added to the codex. Filelfo's ownership is proved not only by autograph (...) marginal notes, but also by the use of this manuscript as the source of Filelfo's Latin translation of several of these pseudepigraphic letters that were incorporated in his Commentationes Florentinae de Exilio, and by the correspondences between the marginalia accompanying the Commentationes and those in the Laur. Plut. 57.12. (shrink)

Investigating the writings of the Francesco Filelfo (1398-1481), twelve scholars are shedding new light on Filelfo’s intellectual endeavors and literary journey. This collection offers new inroads into Filelfo’s vast oeuvre, and through it to the world of Quattrocento humanism.

La réflexion sur l’éthique et la déontologie des médias en Afrique de l’Ouest suscite diverses questions. Il convient d’abord de clarifier les concepts pour alimenter le débat qui a ses moments forts, notamment pendant les périodes électorales.D’un côté, les professionnels de l’information, les acteurs des médias mettent l’accent sur la nécessaire liberté de la presse et peuvent être en porte-à-faux dans leur pratique avec la philosophie et les règles de la profession. D’un autre côté, différentes institutions, que ce soit les (...) institutions gouvernementales, la société civile ou de « simples » citoyens, s’appuient sur les médias, mais les interpellent au sujet d’une liberté qui ne saurait être sans responsabilité.Il s’agira donc de contextualiser l’environnement d’intervention des médias et d’examiner les réponses données aux problèmes posés y compris par les citoyens dans leurs rapports aux médias. La mise en place d’une législation et de structures institutionnelles – que ce soit les organes de régulation, dans leur diversité, ou de manière plus problématique, les organes d’autorégulation ou le tribunal des pairs – montre qu’il existe une dynamique à prendre en compte dans le dévelop­pement des médias en Afrique de l’Ouest.Enfin, nous nous attaquerons à quelques défis, qu’il s’agisse de la formation des professionnels, de la pratique des médias en période de conflit ou des technologies de l’information et de la communication, pour montrer que l’éthique et la déontologie sont au cœur du développement démocratique en Afrique de l’Ouest et en sont un élément constitutif.

The "decapitated of Fourni". A medical-legal and palaeopathological reexamination The two decapitated human skeletons discovered in 1960 in a bothros connected to the clearing of the latrines of the Maison de Fourni at Delos were published in 1973 (Études déliennes [BCH Suppl. I], p. 173-181) and have since led to divergent interpretations. They are here subjected to a new anthropolical study and, for the first time, to a palaeopathological examination, which leads to unexpected conclusions. Firstly, both victimes would have been (...) feminine. Secondly, the date of their beheading as provided by C-14 analysis is much higher than that proposed based on the historical context. The execution was preceded by a period of shackling and restraint. Finally, the bodies were thrown into a cesspool still in use. This episode cannot be connected to a precise event or social context. Nevertheless, this killing recalls more the ritual killing of a sect than a capital execution. (shrink)

In Éléments de l'art de la teinture, Claude-Louis Berthollet organized and described knowledge of a chemical craft in terms of contemporary chemical science. The resulting intellectual structure of his treatise established a programme and method for the subsequent improvement of dyeing. Berthollet's descriptive and hierarchical systematization of knowledge rendered problems intelligible and isolated them so that they could be attacked and solved by methodical experimentation. This double-edged processes of solving practical problems, first cognitively and then experimentally, provides a key to (...) understanding the way science has contributed to rapid and systematic technological change.

This work contrasts the formalist approach to defining explanation in science, exemplified in the Deductive-Nomenological Model of Carl G. Hempel, with the contextualist approach of Thomas Kuhn. It is argued that both of these attempts to define the explanatory processes of science are inadequate. A connection is made between the view of rationality upon which each view is based and the way that it defines explanation. It is argued that a process of thought, which scientific explanation represents, is considered rational (...) by these thinkers only if it meets the criteria of constraint under a rule, distance from subjective considerations and instrumental connection of method and goal. Given this strong definition of rationality, explanation is defined by both Kuhn and Hempel as thought within the constraint of a theory or a theoretical paradigm. Under this construal, explanation is separated as a process from theory invention which both thinkers hold to involve primarily non-cognitive criteria of choice. It is argued in this work that such a view contradicts the actual practice of science where theory invention seems to be primarily a process of rational explaining. ;A detailed historical case of an attempt to explain organic morphogenesis is given. It centers on the theory of generation of Pierre Louis Moreau de Maupertuis, an 18th Century scientific thinker. This case is meant to illustrate the kinds of cognitive interest and strategies of invention that go into dealing with an explanatory problem in science. ;Finally some general programmatic conclusions are made relating the foregoing arguments and the case, to the need to explore the nature of scientific explanation in the domain of theory invention where the reasoning processes seem to involve analogical reasoning and critical metaphysical thought.

À travers l’étude du système à effet intégrateur de rituels et de cérémonials célébrant la présidente de l’UFF et de la FDIF Eugénie Cotton, promue en autorité universelle dont les vertus renvoient au modèle marial, le présent travail explore la mise en place dans le monde communiste de la guerre froide du versant féminin du culte du leader. Afin d’en saisir les spécificités par rapport à un phénomène historique dont la riche production historiographique des vingt dernières années consacre naturellement et (...) exclusivement la masculinité, y sont examinés plus particulièrement les circonstances qui lui donnèrent naissance, les temps forts qui scandent son cheminement, les mécanismes de sa diffusion et les glissements genrés opérés dans le processus de son invention.

Eugénie Cotton est, à l’exception peut-être des ancien·nes communistes, une figure peu connue des historien·nes et du grand public, même si une modeste rue du 19e arrondissement de Paris porte son nom depuis la fin des années 1970 et lui rend hommage en la qualifiant de « docteur ès sciences, promotrice des droits de la femme ». La biographie que lui consacre Loukia Efthymiou, professeure de langue et littérature françaises à l’Université d’Athènes, et spécialiste d’histoire des femmes et du...

La révision du matériel mis au jour lors des fouilles de P. Orlandini dans le sanctuaire extra-urbain de Bitalemi à Géla dans les années 1960 conduit à s’interroger sur les pratiques rituelles accomplies en ce lieu et sur la fonction de la céramique qu’on y a trouvée. L’attention se porte sur un certain nombre de cratères, dont la fonction principale est le mélange de vin et d’eau. Mettant en doute la consommation de vin durant les Thesmopho­ries célébrées dans le sanctuaire, (...) on s’interroge sur la nature du breuvage le mieux adapté à des fidèles rassemblées en l’honneur de Déméter et qui pourrait avoir été préparé dans les cratères. Puisque les abeilles et le miel jouent un rôle central en relation avec les eugeneis gynaikes (les épouses légitimes et les mères qui participent à la fête), l’article fait l’hypothèse que, durant cette fête, les cratères ont pu être utilisés pour le mélange de l’hydromel, une boisson de tradition ancienne, composée d’eau et de miel, et au pouvoir enivrant.

Katherine Wilson-Chevalier propose avec Patronnes et mécènes en France à la Renaissance une somme qui marquera l’histoire du mécénat féminin. Les Anglo-Saxons ont un joli nom pour définir ce patronage au féminin, ils parlent de matronage, et c’est précisément à cette pratique qu’est consacré cet ouvrage fondamental. Il nous propose une galerie de fortes femmes destinées à jouer un rôle politique dans la France du XVIe siècle, mais aussi protectrices des arts. Certaines sont fort connues et se...

In the aftermath of the Spanish War, the Catalan philosopher Eugeni d'Ors and the Spanish philosopher José Ortega y Gasset offered a reading of Einstein’s theory of relativity in which discussions of unity and plurality connected their respective synthetic philosophies and nationalist projects of political and cultural analysis and reform. Besides their philosophical views, references to Einstein tracked their territorial concerns and personal circumstances in the relations between Catalonia, Spain and Europe. Einstein’s theory symbolized the saving connection between the classical (...) and the modern, Europe and the Mediterranean, and science and philosophy. In this paper I focus on the case of Ors in relation to Catalan nationalism and the project he called Noucentismeand the case of Ortega in relation to Spanish nationalism and his political philosophy in España Invertebrada.

Quines són les causes del dèficit filosòfic que arrossega la cultura catalana contemporània? Aquest llibre ofereix un panorama bastant complet —i amarg— de les condicions acadèmiques i extraacadèmiques en què s’ha hagut de conrear als Països Catalans la filosofia, tota la filosofia, centrant-se, això sí, en les aventures personals i col·lectives dels qui han tingut la vel·leïtat de dedicar-se a la lògica. Hi són narrades amb amenitat i lucidesa l’estada de Bertrand Russell a Barcelona, la defenestració d’Eugeni d’Ors, les aberracions (...) docents de Josep Daurella i Rull, la breu i fulgurant trajectòria intel·lectual de Joan Crexells, les peripècies eclesiàstiques de David Garcia Bacca i Miquel Soy, l’exili de Josep Ferrater Mora i la gestació del seu voluminós Diccionario de filosofía, la marginació de Manuel Sacristan, els conflictes de la Facultat de Filosofia de València en els anys 70... El resultat és una història de la filosofia apartada en molts aspectes de la imatge «abstracta» i «idealitzada» que sol oferir la historiografia filosòfica a l’ús. (shrink)

La filosofía práctica abre paso a diferentes temas. Se trata de entender el papel de la filosofía misma y, además, señalar sus implicaciones con la formación de las ideas. El caso de Alemania es especialmente significativo, donde la filosofía experimenta una especie de tensión entre la continuidad o la renovación. Esa tensión puede ser identificada también en América Latina o en Brasil, de modo especial por sus patrones foráneos y exógenos. Además del positivismo francés, hubo también una especie de Eugenia (...) racial. Lo que hoy se conoce de Brasil supone una trayectoria histórica que la filosofía intercultural exige reconstruir para entender la diversidad de sus matices y las características de su gente. The practical philosophy opens the way to different subjects. It treats to understand the role of the philosophy itself and, besides, to indicate its implication with the ideas formation. The German example is especial expressive, where the philosophy tries a kind of tension between the continuation and the renewal. This tension can be to found in Latin America or Brazil, specially by their foreign and external patterns. Besides the French positivism, there was a kind of racial Eugenie in Brazil. What we know about Brazil today supposes a historical course. The intercultural philosophy demands to reconstruct this course, so the diversity of nuances and the characteristic of people can be understood. (shrink)

A partir da temática abordada no filme Gattaca - a experiência genética , que trata de uma sociedade adepta da eugenia; mostraremos quais são as implicações morais que essa prática pode ocasionar em uma sociedade, bem como as diversas discriminações. Em contra-argumento a essa prática, abordaremos a teoria de Peter Singer em prol do princípio da igual consideração de interesses, demonstrando que dessa maneira teríamos sociedades menos discriminatórias. Enfim, queremos mostrar que caso não nos alertemos para as questões abordadas por (...) Singer, nós, agentes morais, faremos emergir uma sociedade preconceituosa, tal como vemos no filme Gattaca.: From selected themes in the movie Gattaca - A genetic experiment that describes a eugenics society, we will show what are the moral implications of the eugenic practice to the society as well as its several kinds of discrimination. We will argue against such practice by appropriating Peter Singer’s theory on behalf of the principle of equal consideration of interests by showing that societies based on it would be less discriminatory. Finally, we show that if we do not consider the issues raised by Singer we, moral agents, will make emerge a prejudiced society similar to that narrated by the movie Gattaca. Key words : Moral, Equality, Eugenie, discrimination. (shrink)
