The "mouchard" in panoramic literature
No full textThis study aims at analysing some problems related to the representation of the mouchard during the July monarchy by comparing three texts belonging to the field of panoramic literature: the article Espions in Louis-Sébastien Mercier's Tableau de Paris (1788); Armand Durentin's L'agent de rue Jérusalem in Français peints par eux-memes (1839-1842) and Balzac's Un espion à Paris in Le Diable à Paris (1844-1845). If Mercier's text serves as a model for later works, we will try to show how, through the 19th-century texts, this figure is involved in a broader operation of exploration of the lesser-known Parisian milieus considered more dangerous, giving rise to attempts of definition and classification with original implications. In this perspective, the caricature acts both as a visual support that dialogues with the written texts and as thematic, hermeneutic and stylistic baggage capable of bringing out the despicable but fascinating character of the spy

No full textIn this paper we present a methodology for the solution of binary systems that allows the simultaneous use of all the available information. We give a statistical criterion to judge about the quality of the results. This methodology, based mainly on the Wilson-Price procedure devised by our group for the solution of binary systems (by Barone et al., in 1988 and 1990 and Milano et al. in 1989), has here been applied to the analysis of four W UMa binaries for which the existing solutions were, for different reasons, unsatisfactory. We show the cases for which more observational data are necessary or those for which a better analysis would be sufficient to give final answers.
The new solutions found for the four systems fit well the data, overcome the discrepancies among results and observations found by previous investigators, and confirm that these systems belong to the W-type category.
Finally, a working hypothesis on a possible new correlation that might link DT, q and the filling factor F of W UMa systems is shown, extending that suggested by Sarna & Fedorova in 1988
