Verso una terceira margem cinematografica: difficoltà e luoghi comuni nella trasposizione dei racconti di Guimarães Rosa
No full textIl presente saggio vuole evidenziare la tipologia di difficoltà insite nella trasposizione cinematografica delle opere di João Guimarães Rosa. Difatti, gli ostacoli che la maggior parte dei registi trova nella
ricerca di un equivalente creativo del magma letterario di JGR sono tali che la maggior parte delle trasposizioni hanno raramente superato la soglia della mediocrità
Palavras de Rosa: análise estilométrica da obra de João Guimarães Rosa
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Literatura, Florianópolis, 2013.Nesta tese analisamos a obra literária de João Guimarães Rosa a partir da estilometria, com o objetivo de buscar as características do estilo rosiano que sejam possíveis de detectar por meio de ferramentas informatizadas de análise estatística. Nossa tese é verificar se esse tipo de estudo permite confirmar ou complementar intuições derivadas de leituras convencionais e, além disso, oferecer novos elementos textuais e estilísticos que nem sempre estão explícitos no texto. Para isso, privilegiaremos três estudos rosianos: Signo e sentimento (SPERBER, 1982) sobre a organização da linguagem de Rosa; O insólito em Guimarães Rosa e Borges (COVIZZI,1978), a qual propõe uma linha cronológica de expressão e explicação da obra rosiana; João Guimarães Rosa: travessia literária, (DANIEL, 1968), que afirma haver uma separação do léxico rosiano em duas fases: uma rural e outra urbana. A ferramenta estatística adotada foi o programa Hyperbase, de Étienne Brunet. Para os procedimentos de análises, trabalhamos com duas bases, uma com a cronologia de produção de escrita das obras e outra seguindo a cronologia de primeira publicação das obras, que foram respeitadas a fim de viabilizar a verificação da evolução e do crescimento do vocabulário do escritor. Levantamos muitas características do léxico rosiano, dentre elas verificamos que mais da metade de seu vocabulário não se repete; e que as obras de caráter sertanejo apresentam vocabulário menos diversificado. Por fim, veremos como Guimarães Rosa, ao final de sua carreira literária, tratou mais do seu material linguístico.Résumé : Cette thèse s'occupera de l'oeuvre littéraire de João Guimarães Rosa à partir de la stylométrie, ayant pour objectif la recherche de caractéristiques du style de l'auteur qui puissent être identifiées par moyen d'outils informatisés d'analyse statistique. Notre thèse consiste à verifier si ce type d'étude permet de confirmer ou d'enrichir des intuitions résultantes de lectures conventionnelles et aussi à offrir de nouveaux éléments textuels et stylistiques qui ne sont pas toujours explicites dans le texte. Pour cela, on privilégiera trois études sur l'écrivain : Signo e sentimento (SPERBER, 1982), texte sur l'organisation du langage de Rosa ; O insólito em Guimarães Rosa e Borges (COVIZZI, 1978), qui propose une frise chronologique de l'expression et explication de l'oeuvre de Rosa ; João Guimarães Rosa, travessia literária, (DANIEL, 1968), selon laquelle il y a deux phases concernant le lexique de l'écrivain : l'une rurale et l'autre urbaine. L'outil statistique adopté a été le logiciel Hyperbase, d'Étienne Brunet. Pour le procédés d'analyse, on a travaillé avec deux bases, à savoir, l'une qui contenait la chronologie de production d'écriture des oeuvres ; l'autre, la chronologie de la première publication des oeuvres, considérée dans ce travail afin de rendre possible une investigation effective de l'évolution et de l'expansion du lexique de l'auteur. Parmi la grande quantité de donnéés recuillies, on a pu constater que plus de la moitié de son lexique ne se répète pas. En outre, les oeuvres "sertanejas" présentent moins de variations lexicales. Pour conclure, on démontrera comment Guimarães Rosa, à la fin de sa vie, s'est occupé davantage de son matériel linguistique.Mots clés: Guimarães Rosa. Stylométrie. Statistique textuel
Lo spirito anarchico
No full textIl presente saggio introduce il volume di cui l'autrice è anche curatrice e traduttrice dei contributi internazionali ivi presenti. Dopo aver introdotto in Italia il contributo di Nathalie Zaltzman con la cura e traduzione del suo ultimo libro (Lo spirito del male, Borla, 2011), oltre che del saggio «Un problematico raccordo di memoria» (2010, in Per un’etica del disagio, Filema), De Rosa ne prosegue l'opera di diffusione ideando e dirigendo questa collaborazione internazionale che persegue un confronto scientifico tra autorevoli psicoanalisti del Quatrième Groupe ed il gruppo di ricerca interdisciplinare di cui è animatrice, "Rileggere il disagio", da tempo impegnato sul tema del disagio della civiltà e delle sue variazioni nell’orizzonte contemporaneo. Figura originale nel panorama psicoanalitico contemporaneo, Nathalie Zaltzman (1933-2009) ha segnato con Piera Aulagnier la vitalità scientifica del Quatrième Groupe, tra le società psicoanalitiche francesi contemporanee più impegnate nel campo della psicoanalisi applicata. Rinvigorendo il legame tra individuale e collettivo incardinato solidamente nella clinica psicoanalitica, e nella convinzione che la psicoanalisi vada intesa come strumento del lavoro di civiltà (Kulturarbeit), Zaltzman ha posto questioni coraggiose sul rapporto tra Kulturarbeit e male estremo: le potenzialità e le aporie del lavoro di civiltà; la resistenza dell’uomo di fronte alla barbarie; l’inumano nell’umano; il totalitarismo di eros e la funzione vitale di thanatos in situazioni estreme. Riferimento, quest’ultimo, al concetto di pulsione anarchica introdotto da Zaltzman che percorre carsicamente la sua intera produzione scientifica e che costituisce il fil rouge del saggio introduttivo di De Rosa che qui si presenta. Attraversando l’opera di Zaltzman e analizzando il dibattito scientifico della comunità psicoanalitica francese e canadese nei convegni e nei volumi a lei dedicati post mortem, De Rosa approfondisce il concetto di pulsione anarchica come operatore di resistenza di fronte alle forme di impossessamento totalitario nelle dimensioni del collettivo e dell’individuale. Siamo, dunque, in un’area di nicchia della ricerca umanistica, quella della ricerca psicoanalitica applicata alle questioni di civiltà, ma che appare non anodina per il suo sforzo di portare avanti uno sguardo integrato, interdisciplinare, sulle problematiche che funestano la nostra contemporaneità: l’avanzare dei fanatismi, le politiche totalitarie, le nuove forme di malessere che destrutturano le società civilizzate
Empirical fragility curves for masonry buildings struck by the 2016 Central Italy earthquake
No full textThe prevention of seismic risk at urban scale can be pursued through the estimate of the probability to reach or exceed a certain
damage grade given the seismic input. In this framework, seismic fragility curves are nowadays of large interest as they express
this probability in a synthetic way, also extended to large-scale applications. Real damage data are crucial in making more reliable
predictions of damage occurrence, although they can be influenced by a proper definition of the structural types and the
completeness of observations. The paper shows the empirical fragility curves obtained for a sample of 2263 masonry buildings
located within 19 historical centers struck by the 2016 Central Italy earthquake. The damage grade was evaluated according to the
European Macroseismic Scale (EMS-98), also considering undamaged buildings, at the end of the sequence that spanned between
August and October. The buildings largely underwent several repairs and strengthening actions with reinforced concrete elements
starting from the 1980s. The systematization of the structural features led to a taxonomy for strengthened and original buildings,
which, based on the observed damage patterns, was matched to the EMS-98 vulnerability classification. The sample ranges from
class A (worst behavior) to D (best behavior). Class A was typically assigned to original buildings (without interventions) or illadvisedly tampered ones, i.e., those in which interventions had an unfavorable contribution to their seismic behavior. Class D
described buildings with properly designed strengthening interventions, classes B and C intermediate situations. Fragility curves
were obtained per each vulnerability class, as a function of the highest peak ground acceleration (PGA) observed in the sequence
from ShakeMaps. The results were then compared to other empirical fragility model
Implementation of ROSA radio occultation data handling into EUMETSAT and GRAS SAF processing
No full textTopic of the GRAS-SAF Visiting Scientist activity 16 has been the implementation of ROSA radio occultation data handling into EUMETSAT and GRAS SAF processing tools. ROSA data referred to observations taken on-board OCEANSAT-2 mission. Even if we are talking of standard Radio Occultation data, the format of raw binary data is peculiar, and processing chains already implemented for other Radio Occultation missions, should be adapted to this further format. Moreover, ROSA antennas, ROSA coverage, ROSA sampling rate, etc. are different from GRAS or COSMIC data. Main goals of this VS activity have therefore been the implementation of ROSA processing into the EUMETSAT YAROS prototype (in order to produce excess-phases, amplitudes and bending angles over impact parameter) and into the GRAS SAF ROPP processor (for the processing into bending angle, refractivity and higher level atmospheric profiles), dealing mainly with data interfacing issues. The first part of the activity was carried out in EUMETSAT, where the YAROS prototype has been adapted to handle ROSA data. Before doing that, an in-depth analysis has been done in order to identify all the ROSA data characteristics and issues. In particular, the Thales Alenia Space "decoding" software has been completely review, in order to understand how these data were formatted inside the native binary ROSA data stream coming from the OCEANSAT-2 telemetry, and inside the standard Level1 Engineered data file available for users. This preliminary analysis allows the definition of several ROSA data structures that could be easily implemented directly inside the YAROS prototype. At the end of this first part, two different releases of the EUMETSAT prototype were available: the first one able to manage only the scientific ROSA engineered data, containing the basic observables for Radio Occultation purposes (the Level 1a data, the one normally made available for users); the second one which implements ad-hoc data structures where all the data generated by the ROSA receiver (and contained in the raw binary format, the Level 0 data) are stored. About thirty hours of ROSA observations, for which orbit and clocks were already available, were used as input to the adapted YAROS/ROSA prototype and completely analyzed. Only the YAROS prototype adapted to ROSA Engineered Level 1 format was used. A quality check of L1 and L2 basic observables (mainly L1 and L2 Excess-Phase and Signal-to-Noise ratio profiles) contained in the Level 1a YAROS output file has been performed. Even if a complete ROSA dataset is available for one entire month of observations, the production of all the necessary POD products for the entire month was not undertaken. Its in-depth analysis will be carried out in the future, when the Memorandum of Understanding between Italian Space Agency and EUMETSAT for the ROSA data processing will be signed. During this activity we preferred to concentrate the work on the YAROS prototype adaptation to ROSA data, making the prototype ready to handle all the ROSA data available, and not only the one contained in the Level1 Engineered data normally available to the user. In order to let these NetCDF Level1a YAROS/ROSA output files to be further processed into higher Radio Occultation products, a converter from NetCDF 4.0 to NetCDF 3.0 file (with the required data structures correctly set for the GRAS-SAF ROPP processing). This was performed during the second part of the Visiting Scientist activity at DMI, where YAROS/ROSA Level 1a files were both processed to bending angles, to refractivity and higher level products. Analysis of the bending angle and refractivity data against ECMWF and collocated radio occultation data were also performed, in order to have a preliminary idea on the quality of the final atmospheric products that can be achieved analyzing ROSA data. Moreover, YAROS/ROSA Level 1a files were also processed into Level 1b products (bending angle profiles) using the L1a2L1b YAROS code and compared with the correspondent forward modelled ECMWF collocated data. As a general comment on the ROSA data quality it has to be noted that, even thought L1 data are in line with that observed by the other Radio Occultation instruments, L2 data shows some problems. Problems which are mainly related to OCEANSAT-2 issues. ROSA on-board OCEANSAT-2 was equipped only with the Velocity Radio Occultation antennas, therefore only rising events can be recorded. Moreover local multipath on-board OCEANSAT-2 is very strong because of solar panels and because of the scatterometer antenna which both are moving. In particular this local multipath was not modelled or measured on ground, since an in-orbit platform manoeuvre was made necessary and created a permanent and unexpected yaw bias on the platform. And these problems mainly impact L2 tracking, which basically starts too high in atmosphere and which is affected by long data gaps. Only for a small number of events L2 is available in troposphere. In these cases, the quality of atmospheric profiles retrieved using the GRAS-SAF ROPP processing chain is in line with that obtainable from other Radio Occultation missions. But, for all the other cases for which L2 is available higher in the atmosphere, modifications to the L2 extrapolation/interpolations and different Statistical Optimization setting are probably necessary to adapt the GRAS-SAF ROPP_PP Processor to such bad data. From the other point of view, YAROS software correctly handle such ROSA data, even if a high number of rejected profiles are seen with respect what normally happens in processing data from other Radio Occultation observation
Optimized Ultrasound-Assisted Enzymatic Extraction of Phenolic Compounds from Rosa canina L. Pseudo-Fruits (Rosehip) and Their Biological Activity
No full textTwo techniques, namely, optimized ultrasound-assisted extraction (UAE) and enzyme-assisted extraction (EAE), were used to promote the extraction of phenolic compounds from the pseudo-fruits of Rosa canina L. (RC). For UAE, an optimization process based on the design of experiment (DoE) principles was used for determining the dependence between three variables (i.e., time of extraction, ultrasound amplitude, and the material-to-water ratio) and the total phenolic content of the samples. For EAE, a 2:1:1 pectinase, cellulase, and hemicellulase enzymatic blend was used as pre-treatment for optimized UAE, inducing a higher total phenolic content. The untargeted phenolic profiling approach revealed a great abundance of lower molecular weight phenolics (1.64 mg Eq./g) in UAE-RC extracts, whilst gallic acid (belonging to hydroxybenzoic acid derivatives) was the most abundant individual compound of both extracts. The unsupervised multivariate statistics clearly discriminated the impact of enzymatic pre-treatment on the phenolic profile of RC pseudo-fruits. Finally, Pearson’s correlation coefficients showed that anthocyanins, phenolic acids, and tyrosol derivatives were those compounds mostly correlated to the in vitro antioxidant potential of the extracts, whilst negative and significant (p < 0.05) correlation coefficients were recorded when considering the enzymatic inhibition activities. The highest enzyme-inhibitory activity has been identified against α-glucosidase, which indicates an antidiabetic effect
Determination of the Chemical Composition, Antioxidant and Antimicrobial Activities of Different Parts of Rosa canina L. and Rosa pimpinellifolia L. Essential Oils
No full textToday, the use of essential oils is increasing day by day, and it is considered as raw materials in many industries. Therefore, this study aims to identify the essential oil profile, antioxidant and antimicrobial activity of Rosa canina L. and Rosa pimpinellifolia L. reveal their potential use in the industry. Essential oils that were obtained in 2013-2014 from different parts (flower, leaf, stem, and fruit) of Rosa canina L. and Rosa pimpinellifolia L. by the hydro-distillation method were analyzed by GC/MS. The dominant components in Rosa canina L. were found as trans-geraniol in the flowers (42.08 % for 2013), linalool in the leaves (11.55 % for 2014), and stem (14.91 % for 2013) and vitispirane in the fruits (37.19 % for 2014). The dominant components in R. pimpinellifolia L. were found as heneicosane in the flowers (22.07 % for 2014), gamma-elemene in the leaves (30.21 % for 2013), linalool in the stem (14.76 % for 2013) and the fruits, (E)-2-hexenal for those collected in 2013 (14.09 %). The IC50 and FRAP values of the samples ranged from 127.54 to 142.22 mu g/g and 121.43 to 296.78 mu mol TE/g, respectively. According to the results obtained, both R. canina L. and R. pimpinellifolia L. were found to show poor antioxidant values of DPPH and FRAP. In general, it was determined that the essential oils obtained from different plant parts of both species had a moderate antimicrobial effect against Escherichia coli, Staphylococcus aureus, Bacillus subtilis, Bacillus cereus, and Pseudomonas aeruginosa.WOS:0006603262000012-s2.0-8510781136
Accents and dialect as a source of humour: the case of Rio
No full textThe present work stems from a research project carried out with G. De Rosa on the dubbing and subtitling of the film Rio (Saldanha, 2011), produced by Blue Sky Studios, in which the original English dialogues are compared and contrasted to translations into several languages, i.e. Brazilian Portuguese and Italian, making occasional reference to other dubbed versions, e.g. the Mexican, Spanish and Portuguese versions. In particular, this paper is devoted to an analy-sis of the Italian dubbing of Rio into Italian, focusing especially on humorous aspects and sociolinguistic variation and drawing a comparison with another animated film, i.e. The Aristocats (Reitherman, 1970)
