The power of fiction and its controversies in Azar Nafisi’s portrayals of a new compliant nationality
No full textAccording to Anderson’s positions on nation and nationalism as cultural artifacts, Azar Nafisi’s literary memoirs show a controversial case study, focused on the ambiguities of the exile discourse and of the so-called «imaginative knowledge». Through the lens of a recurring celebration of Western myths of freedom, a series of stereotypes and paradoxes will be examined, in relation to the censorship experienced by the author under the Islamic Republic of Iran. Moreover, Nafisi’s juxtaposition of political and literary perspectives will be shown as an ambivalent narrative strategy, despite her search for a true self without any ideological engagement. In the end, the explored duality between oriented dissertations and pure imaginative recreations will enable to reconsider Nafisi’s memoirs as committed depictions of a Westernized national legacy
La necessità come categoria giuridica: un’ipotesi di lavoro per Jacopo Menochio
No full textNella biblioteca trivulziana di Milano si conserva, in un unico voluminoso manoscritto, il trattato De necessitate, eiusque privilegiis et prerogativis di Jacopo Menochio.L’impostazione scelta da Menochio può essere meglio compresa grazie al confronto con altri trattati cinque-seicenteschi che affrontano temi dalla stessa natura trasversale e articolata (la povertà, la malattia e simili).Benchè l’opera sia incompleta, la lettura si rivela di notevole interesse sia nella prima parte, più rifinita e meditata, dedicata all’introduzione teorica sul concetto filosofico-giuridico di necessità, sia in quella, assai più confusa e frammentaria, in cui l’autore progettava di analizzare in modo analitico i numerosi privilegia, che nell’ambito del diritto si collegano alle diverse concezioni e situazioni di necessità. Proprio il carattere disorganico del codice lo rende anzi di particolare rilievo: oltre a dare un saggio del sapere giuridico del professore pavese, alle prese con un concetto dalle molteplici sfaccettature teorico-pratiche, il testo offre una interessante visione del metodo di lavoro con il quale va costruendosi un trattato su un tema così complesso, e ci mostra il modo in cui un illustre giurista dell’età del tardo diritto comune padroneggia l’immensa mole delle fonti e delle autorità di riferimento per giungere alla soluzione di ogni possibile caso concreto.In the Trivulziana Library in Milan, the treatise De necessitate, eiusque privilegiis et prerogativis, by Jacopo Menochio, is preserved in a single voluminous manuscript.The method chosen by Menochio can be better understood through comparison with other sixteenth-seventeenth century treatises that deal with themes of the same transversal and complex nature (poverty, illness and the like).Although the work is incomplete, the reading reveals itself of considerable interest both in the first part, more refined and meditated, dedicated to the theoretical introduction on the philosophical-juridical concept of necessity, as in the much more confused and fragmentary part, in which the author planned to analytically analyze the numerous privilegia, which in the field of law are connected to the different conceptions and situations of necessity. The very disorganized nature of the code gives it a particularly significant: in addition to providing a sample of the juridic knowledge of the professor from Pavia, dealing with a concept of multiple theoretical and practical facets, the text offers an interesting vision of the working method with which a treatise on such a complex theme is being constructed, and shows us the way in which an illustrious jurist of the late ius commune era masters the immense mass of sources and reference authorities to reach the solution of every possible concrete case
Contributo alla conoscenza del genereEchium: I.Echiumdella Sardegna
No full textThe author makes in this work a survey of the species of the
genusEchium, known up to now in Sardinia, and points out some of the
problems connected with them. For some species further research in the
distribution area of the genus (with particular regard to Italy) and accurate
comparisons with similar entities are necessary in order to ascertain their
specific character, for some species their actual presence in Sardinia has to
be verified.
The following species have been recognized:E. italicumL.;E. asperrimumLam.;E. plantagineumL.;E. parviflorumMoench;E. sabulicofumPomel;E. creticumL. ssp.creticume ssp.coincyanum(Lac.) Fernandes;E. vulgareL.;E. pustulatumS. et S.
A careful study is still necessary to come to definitive conclusions onE. arenariumGuss. andE. elegansLehm
Formation of tritium-labeled polysialylated gangliosides in the cytosol of rat cerebellar granule cells in culture following administration of [3H]GM1 ganglioside
No full textAbstractGM1 ganglioside tritium-labeled at C-3 of sphingosine has been administered to rat cerebellar granule cells. Tritiated polysialylated gangliosides were observed in the cytosol of the cells, where they resulted in a higher amount after a short period of chase. This, together with the data showing an increase of the tritiated polysialylated gangliosides in the total particulate fraction in parallel to the prolonging of the chase period, suggests that cytosolic gangliosides could be a way of transporting neosynthesized gangliosides from the Golgi apparatus to the plasma membranes
Age-related changes of the ganglioside long-chain base composition in rat cerebellum
No full textThe ganglioside mixture from the cerebellum of young, 6 month old and two years old rats, was fractionated by reversed phase high performance liquid chromatography, each ganglioside homogeneous in the oligosaccharide chain as well as in the long-chain base being subsequently quantified. Two long-chain bases, LCB, were components of the five major gangliosides GM1, GD1a, GD1b, GT1b and GQ1b, these being the C18:1 LCB and C20:1 LCB. The content of C20:1 ganglioside molecular species was lower than that of the C18:1 one. In very young animals, day 8, the C20:1 ganglioside species represented about 8% of the total ganglioside content, then they progressively increased and reached, at 2 years, about 42% of the total. C18:1 GD1a and C18:1 GT1b, were the major species in young animals and reached their highest content at day 29, being 1.45 and 1.28 nmol/mg protein, respectively. The content of these two species decreased in adult and old animals and at two years it was 0.71 and 0.82 nmol/mg protein, respectively
Selection of visual information for lightness judgements by eye movements
No full textWhen judging the lightness of objects, the visual system has to take into account many factors such as shading, scene geometry, occlusions or transparency. The problemthen is to estimate global lightness based on a number of local samples that differ in luminance. Here,we showthat eye fixations play a prominent role in this selection process. We explored a special case of transparency for which the visual system separates surface reflectance from interfering conditions to generate a layered image representation. Eye movements were recorded while the observers matched the lightness of the layered stimulus. We found that observers did focus their fixations on the target layer, and this sampling strategy affected their lightness perception. The effect of image segmentation on perceived lightness was highly correlated with the fixation strategy and was strongly affected whenwe manipulated it using a gaze-contingent display. Finally, we disrupted the segmentation process showing that it causally drives the selection strategy. Selection through eye fixations can so serve as a simple heuristic to estimate the target reflectance. © 2013 The Author(s) Published by the Royal Society. All rights reserved

Identità in transito: prove di riscrittura del sé nella memorialistica e narrativa femminile irano-americana
No full textBefore and after the Iranian Revolution, the experience of restrictions and gender confinement drove many Iranian women writers to fight for their forbidden role. What many of them now call their first exile at home went on until the chance of migration, above all to Europe and to the Usa, changed the perils of writing under Iranian censorship into a free, but unbalanced condition aware of cultural dissociations.
Those dissociations are not simply due to diasporic estrangement, but to a more confused doubling, which is rooted in a quest for the self that passes through hyphenation and in-betweenness. Moreover, if the veil often emerges as a narrative symbol of women’s oppression, it sometimes acquires the valency of a dramatic “fourth wall”.
This thesis aims to overthrow that “invisible wall”, in order to show a relationship between dramatization and new writing by the women of the Iranian diaspora. In line with Brechtian epic drama based on the concept of estrangement, it will explore estrangement both as an existential condition and as the distance required to rewrite the self through new roles.
More in detail, if the author lives between two worlds and tries to depict their dualisms, she also becomes the playwright of her past and present selves. The metaphors and dualisms will be examined through a comparison of some memoirs and novels by Iranian-American women writers – such as Azadeh Moaveni, Firoozeh Dumas, Nahid Rachlin, Porochista Khakpour and Azar Nafisi – coming from different generations and cultural heritages. Each narration will be analysed as a dramatic scene of memories and linguistic splits, which dramatize recurring senses of estrangement and turn them into a more “visible wall” of identities in transit
