O mito de don juan e a subjetividade moderna

The legendary Don Juan character inhabits the popular imaginary with such a vibrancy of a myth, despite its slight recognition as such by the scientific literature. The purpose of this article is to verify if Don Juan’s play can be understood, scientifically, as a modern myth, as well as understand its mythical nature and its relation to the modern man. A structural and historical analysis of the two first plays on Don Juan has guided us: the one written by Tirso de Molina in 1630, and the one by Molière, written in 1665. The studies allow us to say that Don Juan is a typical modern myth, once it is constituted by narratives that expose a world looming under the signs of individualism, hedonism, arrogance and audacity forged under the appeals of sexual desire.

Solvation in aqueous binary mixtures: consequences of the hydrophobic character of the ionic liquids and the solvatochromic probes

Information on the solvation in mixtures of water, W, and the ionic liquids, ILs, 1-allyl-3-R-imidazolium chlorides; R = methyl, 1-butyl, and 1-hexyl, has been obtained from the responses of the following solvatochromic probes: 2,6-dibromo-4-[(E)-2-(1-R-pyridinium-4-yl)ethenyl] phenolate, R = methyl, MePMBr2; 1-octyl, OcPMBr(2), and the corresponding quinolinium derivative, MeQMBr(2). A model developed for solvation in binary mixtures of W and molecular solvents has been extended to the present mixtures. Our objective is to assess the relevance to solvation of hydrogen-bonding and the hydrophobic character of the IL and the solvatochromic probe. Plots of the medium empirical polarity, E-T(probe) versus its composition revealed non-ideal behavior, attributed to preferential solvation by the IL and, more efficiently, by the IL-W hydrogen-bonded complex. The deviation from linearity increases as a function of increasing number of carbon atoms in the alkyl group of the IL, and is larger than that observed for solvation by W plus molecular solvents (1-propanol and 2-(1-butoxy)ethanol) that are more hydrophobic than the ILs investigated. This enhanced deviation is attributed to the more organized structure of the ILs proper, which persists in their aqueous solutions. MeQMBr(2) is more susceptible to solvent lipophilicity than OcPMBr(2), although the former probe is less lipophilic. This enhanced susceptibility agrees with the important effect of annelation on the contributions of the quinonoid and zwitterionic limiting structures to the ground and excited states of the probe, hence on its response to both medium composition and lipophilicity of the IL.

Libro, diaspora e ri-costruzioni identitarie. Per una storia della tipografia sefardita portoghese nell'Italia del Cinquecento

Il lavoro ripercorre le tracce che gli ebrei portoghesi, esuli dopo il biennio 1496-97, lasciarono nel loro cammino attraverso l'Europa. In particolare, l'interesse si concentra sulla breve parentesi italiana, che grazie all'apertura e alla disponibilità  di alcuni Signori, come i Gonzaga di Mantova, i Medici, i Dogi della Serenissima e gli Este, risulta ricchissima di avvenimenti e personaggi, decisivi anche per la storia culturale del Portogallo. L'analisi parte evidenziando l'importanza che ebbe la tipografia ebraica in Portogallo all'epoca della sua introduzione nel Paese; in secondo luogo ripercorre la strada che, dal biennio del primo decreto di espulsione e del conseguente battesimo di massa, porta alla nascita dell'€™Inquisizione in Portogallo. Il secondo capitolo tenta di fare una ricostruzione, il più possibile completa e coerente, dei movimenti degli esuli, bollati come marrani e legati alle due maggiori famiglie, i Mendes e i Bemveniste, delineando poi il primo nucleo di quella che diventerà  nel Seicento la comunità  sefardita portoghese di Amsterdam, dove nasceranno le personalità  dissidenti di Uriel da Costa e del suo allievo Spinoza. Il terzo capitolo introduce il tema delle opere letterarie, effettuando una rassegna dei maggiori volumi editi dalle officine tipografiche ebraiche stanziatesi in Italia fra il 1551 e il 1558, in modo particolare concentrando l'attenzione sull'€™attività  della tipografia Usque, da cui usciranno numerosi testi di precettistica in lingua ebraica, ma soprattutto opere cruciali come la famosa «Bibbia Ferrarese» in castigliano, la «Consolação às Tribulações de Israel», di Samuel Usque e la raccolta composta dal romanzo cavalleresco «Menina e Moça» di Bernardim Ribeiro e dall'ecloga «Crisfal», di un autore ancora non accertato. L'ultimo capitolo, infine, si propone di operare una disamina di queste ultime tre opere, ritenute fondamentali per ricostruire il contesto letterario e culturale in cui la comunità  giudaica in esilio agiva e proiettava le proprie speranze di futuro. Per quanto le opere appartengano a generi diversi e mostrino diverso carattere, l'€™ipotesi è che siano parte di un unicum filosofico e spirituale, che intendeva sostanzialmente indicare ai confratelli sparsi per l'Europa la direzione da prendere, fornendo un sostegno teoretico, psicologico ed emotivo nelle difficili condizioni di sopravvivenza, soprattutto dell'integrità religiosa, di ciascun membro della comunità.

INTERACTIVE CONTROLS OF WATER TABLE POSITION AND PLANT FUNCTIONAL TYPES ON PEAT POREWATER CHARACTER IN NORTHERN BOG ECOSYSTEMS: IMPLICATIONS FOR CARBON CYCLING DYNAMICS

Northern wetlands, and particularly peatlands, have been shown to store around 30% of the world's soil carbon and thus play a significant role in the carbon cycle of our planet. Changes in climate are altering peatland hydrology and vegetation communities. These changes are possibly resulting in declines in the ability of peatlands to sequester carbon because losses through carbon oxidation and mineralization are likely to increase relative to C inputs from net primary production in a warmer, drier climate. However, the consequences of interactive effects of altered hydrology and vegetation on carbon storage are not well understood. This research evaluated the importance of plant species, water table, and their interactive effects on porewater quality in a northern peatland with an average pH of 4.54, ranging from 4.15 to 4.8. We assessed the effects of plant functional group (ericaceous shrubs, sedges, and bryophytes) and water table position on biogeochemical processes. Specifically, we measured dissolved organic carbon (DOC), total dissolved nitrogen (TDN), potential enzyme activity, organic acids, anions and cations, spectral indexes of aromaticity, and phenolic content. Our results indicate that acetate and propionate concentrations in the sedge-dominated communities declined with depth and water table drawdown, relative to the control and ericaceous treatments. DOC increased in the lowered water table treatments in all vegetation community types, and the peat porewater C:N ratio declined in the sedge-dominated treatments when the water table was lowered. The relationship between DOC and ferrous iron showed significant responses to vegetation type; the exclusion of Ericaceae resulted in less ferrous iron per unit DOC compared to mixed species treatments and Ericaceae alone. This observation was corroborated with higher mean oxidation redox potential profiles (integrating 20, 40, and 70 cm) measured in the sedge treatments, compared with the mixed and Ericaceae species treatments over a growing season. Enzymatic activities did not show as strong of a response to treatments as expected; the oxidative enzyme peroxidase and the hydrolytic enzyme phosphatase were the only enzymes to respond to water table, where the potential activity of both enzymes increased with water table drawdown. Overall, there were significant interactive effects between changes in vegetation and water table position on peat porewater composition. These data suggest that vegetation effects on oxidation reduction potentials and peat porewater character can be as important as water table position in northern bog ecosystems.
