A imagem de Alessandro Baricco no Brasil
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Estudos da Tradução, Florianópolis, 2013.Com a intenção de delinear o modo pelo qual o escritor italiano Alessandro Baricco se inseriu no sistema literário brasileiro e os caminhos percorridos pelos seus livros traduzidos, esta dissertação dá voz às experiências tradutórias de seus tradutores. A inserção de Bariccono Brasil tem seu início em 1997, através de uma proposição da Profa. Dra. Roberta Barni à editora Iluminuras da tradução de Oceano Mare. A partir daí, outras sete obras foram publicadas no Brasil, sendo três delas traduzidas por Roberta Barni e as outras quatro por quatro tradutores diferentes. De um lado, considera-se o tradutor como figura principal namediação entre culturas, e, de outro, se analisa a realidade desta figuradentro do sistema literário, sua invisibilidade, seus limites e o exercíciode sua profissão. A pesquisa conta, ainda, com críticas e resenhas referentes ao autor italiano publicadas em jornais consagrados no Brasil, considerando estas como parte constituinte da imagem de Baricco refletida em território nacional. Abstract : Intending to delineate the way the Italian writer Alessandro Baricco has been inserted in the Brazilian literary system and the paths his translated books have followed, this thesis gives voice to the translating experiences of his translators. Baricco's insertion in Brazil began in 1997, through a personal project of Dr. Roberta Barni, with her translation of Oceano Mare. Since then, seven other of his works have been published in Brazil, three of which were translated by Roberta Barni and the other four by four different translators. On the one hand,the translator is considered as the main figure in mediation betweencultures and, on the other, this figure's reality is analyzed within theliterary system: its invisibility, its limits and its professional practice. Criticisms and reviews of this Italian author published in well established Brazilian newspapers are also considered, with the understanding that they are part of Baricco's image reflected here
The swrAA gene, regulating swarming behaviour in Bacillus subtilis, is sigD-dependent but displays additional regulative features
No full textIn Bacillus subtilis, a wild-type copy of swrAA gene is necessary for swarming and stimulates swimming motility. The biological function of its product is presently unknown. SwrAA shows no homology to any entry in Protein databases, and no particular feature can be found by in silico analysis. We therefore concentrated our efforts on the expression profile of this gene, in order to gain some insight on the role it plays in the activation of the swarming behavior.
Accurate inspection of swrAA upstream sequence, suggested the presence of sequences (TTGCCT-N17-TACAAT and TAAA-N12-CCCGATAT) for the binding of Sigma A and Sigma D respectively, the latter being almost identical to the consensus. In in vitro transcription assay, we confirmed the promoter dependence on the presence of SigD but no transcription could be detected with E(sigA). In vivo, site-directed mutagenesis of the SigD consensus sequence completely abolishes transcription of a PswrAA-lacZ transcriptional fusion.
swrAA expression is extremely low in conditions where other sigD-dependent genes are normally well expressed but displays additional regulative features which do not affect other sigD-dependent promoters.
We explored the expression profile of PswrAA in the presence of mutations which are known to impair motility. In swimming assays, the positive role of SwrAA is lost in the absence of the DegS/DegU two component system.
Taken together our results (see also the work presented by Amati et al.) point to a central role of SwrAA in the decision process B. subtilis cells face at the end of the exponential growth, possibly finely tuning the responses regulated by DegS/DegU

No full textSocial Network Modeling
No full text The development of stochastic models for the analysis of social networks is an important growth area in contemporary statistics. The last few decades have witnessed the rapid development of a variety of statistical models capable of representing the global structure of an observed network in terms of underlying generating mechanisms. The distinctive feature of statistical models for social networks is their ability to represent directly the dependence relations that these mechanisms entail. In this review, we focus on models for single network observations, particularly on the family of exponential random graph models. After defining the models, we discuss issues of model specification, estimation and assessment. We then review model extensions for the analysis of other types of network data, provide an empirical example, and give a selective overview of empirical studies that have adopted the basic model and its many variants. We conclude with an outline of the current analytical challenges. </jats:p
Deg-U-P Represses Expression of the Motility fla-che Operon in Bacillus subtilis.
No full textBacillus subtilis implements several adaptive strategies to cope with nutrient limitation experienced at the end of exponential growth. The DegS-DegU two-component system is part of the network involved in the regulation of postexponential responses, such as competence development, the production of exoenzymes, and motility. The degU32(Hy) mutation extends the half-life of the phosphorylated form of DegU (DegU-P); this in turn increases the production of alkaline protease, levan-sucrase, and other exoenzymes and inhibits motility and the production of flagella. The expression of the flagellum-specific sigma factor SigD, of the flagellin gene hag, and of the fla-che operon is strongly reduced in a degU32(Hy) genetic background. To investigate the mechanism of action of DegU-P on motility, we isolated mutants of degU32(Hy) that completely suppressed the motility deficiency. The mutations were genetically mapped and characterized by PCR and sequencing. Most of the mutations were found to delete a transcriptional termination signal upstream of the main flagellar operon, fla-che, thus allowing transcriptional readthrough from the cod operon. Two additional mutations improved the {sigma}A-dependent promoter sequence of the fla-che operon. Using an electrophoretic mobility shift assay, we have demonstrated that purified DegU binds specifically to the PA promoter region of the fla-che operon. The data suggest that DegU represses transcription of the fla-che operon, and they indicate a central role of the operon in regulating the synthesis and assembly of flagella
La maturità di Alessandro Fei del Barbiere, in bilico tra Maniera e Riforma
No full textThis article studies the mature career of the Florentine painter Alessandro Fei del Barbiere (1537-1592), beginning with the rediscovery of the 'Ascension' altarpiece formerly in the Albizi Chapel in the destroyed church of San Pier Maggiore, Florence. Studying this painting and others recorded in 1584 by the biographer Raffaello Borghini, such as the two altarpieces for Santa Maria delle Grazie and the Madonna dell'Umiltà in Pistoia, the author reconstructs a body of works showing how in the 1580s Fei gradually went beyond the archaic style of his apprenticeship - he had been trained by Ridolfo del Ghirlandaio and Pierfrancesco Foschi, but was also marked by the Maniera of Vasari - evolving towards naturalism in both mimesis and pictorial handling. In Florence, his development partly parallels that of Santi di Tito and his circle, but Fei was also influenced by a probable sojourn during the early part of that decade in Rome, where he could have been inspired by Girolamo Muziano and the painters working for Pope Gregory XIII. Among other proposals, the author suggests that the artist was responsible for decorating the chancel of Fiesole Cathedral (c. 1584-1589), which consisted of an altarpiece, only rarely discussed by scholars, and a cycle of frescoes hitherto attributed to Nicodemo Ferrucci

Some days are better than others: Examining time-specific variation in the structuring of interorganizational relations
No full textThe generative mechanisms controlling change in interorganizational relations are typically assumed to be time-independent, i.e., operate homogeneously and synchronously over time. In this paper we consider some of the
implications of violating this assumption. We adopt and extend statistical models for relational events to reveal
time-specific variations in mechanisms underlying interorganizational relations observed within a small community
of health care organizations. We find that aggregate estimates of parameters associated with mechanisms
of theoretical interest mask fine-grained temporal variation in relational events sequences. We discuss the implications
of this result for studies of interorganizational relations – and social networks more generally
