Tarabotti fra omissioni e femminismo: il mistero della sua formazione

This paper given at the conference "Donne a Venezia" in May 2008 discloses the complexity of Arcangela Tarabotti (1604-1652), a proto-feminist polemist and writer who lived all her life in a remoted convent, Sant'Anna in Castello, in a remoted part of Venice. Despite having been cloistered at the age of 11, according to her account, she managed to publish her books and become a recognised member of the République des Lettres. How did she manage to develop her incredibly modern ideas, suggesting women should study and work and avoid getting married with astronomical dowries? The article deals with entirely new documents, uncovered in archives and tries to provide an answer to such dearing questions.

L'environnement auditif au travail

À haute intensité, les deux principales sources d'inconfort physique au travail sont la chaleur et le bruit (Pellerin & Candas, 2003). Même à des intensités modérées et faibles, le bruit affecte les performances cognitives, y compris dans les tâches de bureau courantes, mais il le fait de plusieurs manières différentes selon la nature du bruit (par exemple, discours vs. non-discours, intensité sonore, variabilité et prévisibilité etc.) et le type de tâche dans laquelle l'individu ou le groupe est engagé. Il est un peu surprenant, donc, que les individus expriment souvent une préférence pour travailler dans des conditions de bruit modérées (Schlittmeier & Hellbrück, 2009). Les multiples formes de perturbation auditive nuisant aux performances cognitives sont examinées et comparées avec leurs avantages potentiels dans le cadre du travail, résultant du traitement du bruit de fond en termes de sens du lieu, d'apprentissage fortuit des régularités dans le monde auditif, et de commutation intelligente de l'attention.

EXACT AND QUASI-EXACT MODELS OF STRANGE STARS

We construct and compare in this work a variety of simple models for strange stars, namely, hypothetical self-bound objects made of a cold stable version of the quark-gluon plasma. Exact, quasi-exact and numerical models are examined to find the most economical description for these objects. A simple and successful parametrization of them is given in terms of the central density, and the differences among the models are explicitly shown and discussed. In particular, we present a model starting with a Gaussian ansatz for the density profile that provides a very accurate and almost complete analytical integration of the problem, modulo a small difference for one of the metric potentials.

Star products made (somewhat) easier

We develop an approach to the deformation quantization on the real plane with an arbitrary Poisson structure which is based on Weyl symmetrically ordered operator products. By using a polydifferential representation for the deformed coordinates, xj we are able to formulate a simple and effective iterative procedure which allowed us to calculate the fourth-order star product (and may be extended to the fifth order at the expense of tedious but otherwise straightforward calculations). Modulo some cohomology issues which we do not consider here, the method gives an explicit and physics-friendly description of the star products.

BASS CYCLIC UNITS AS FACTORS IN A FREE GROUP IN INTEGRAL GROUP RING UNITS

Marciniak and Sehgal showed that if u is a non-trivial bicyclic unit of an integral group ring then there is a bicyclic unit v such that u and v generate a non-abelian free group. A similar result does not hold for Bass cyclic units of infinite order based on non-central elements as some of them have finite order modulo the center. We prove a theorem that suggests that this is the only limitation to obtain a non-abelian free group from a given Bass cyclic unit. More precisely, we prove that if u is a Bass cyclic unit of an integral group ring ZG of a solvable and finite group G, such that u has infinite order modulo the center of U(ZG) and it is based on an element of prime order, then there is a non-abelian free group generated by a power of u and a power of a unit in ZG which is either a Bass cyclic unit or a bicyclic unit.
