Eine Karriere im Schatten von Rosalba Carriera. Felicita Sartori / Hoffmann in Venedig und Dresden

Felicita Sartori, nata a Pordenone nel 1714 ca. come figlia del notaio Felice Sartori e di Tommasa Scotti, ricevette la sua prima formazione artistica intorno al 1724 da suo zio, il calcografo Antonio dall'Agata a Gorizia. Tramite lo zio la quattordicenne si trasferisce a Venezia dove entra nella bottega-casa di Rosalba Carriera per perfezionarsi nella miniatura e nella pittura a pastello senoché nelle varie tecniche della grafica. Durante gli anni seguenti Felicita diventa, accanto alle sorelle di Rosalba, la collaboratrice piú stretta della Carriera che in questi anni tocca il colmo della fama artistica, dovuto soprattutto al suo strepitoso successo riscosso durante il soggiorno a Parigi dal 1720 al 1721. I numerosissimi incarichi che le giungono da tutta l'Europa incrementano la produttivitá e lasciano supporre che la bottega abbia contribuito in misura notevole a contentare tali richieste. Negli anni dopo il 1730 l'attività di Felicita oltre le varie attività pittoriche entro la bottega della Carriera si estende alla produzione di incisioni per le pubblicazioni di Gaspare Stampa e di Jacques-Bénigne Bossuet. Incide inoltre le stampe dai disegni di Giovanni Battista Piazetta, pubblicati da Antonio Maria Zanetti. La finora anonima collaboratrice della famosa veneziana esce dall'ombra quando, nel 1741, viene nominata artista di corte da Augusto III, principe elettore di Sassonia e ré di Polonia. Trasferitosi a Dresda, si unisce poche settimane dopo la nomina in matrimonio al consigliere di corte Franz Joseph von Hoffmann, che probabilmente aveva concosciuto nel 1740 nello studio veneziano di Rosalba spesso frequentato dall'elettore e del suo seguito. Felicita continua la su attività a Dresda dove nella Gemäldegalerie Alte Meister si conservano tuttora 15 miniature di sua mano. Grazie alle ricerche dedicate a queste opere è stato possibile di aumentare l'œuvre della Sartori di altre opere tra cui una Betsabea al bagno (coll. priv. München) già nelle collezioni reali sassoni. Sembra che l'artista dopo la morte del marito nel 1749, si sia trasferito con un secondo marito a Bamberg ma altre fonti citano la sua presenza a Dresda nel 1753 dove secondo le notizie fornite da Jean Pierre Mariette muore nel 1760 all'età di soli 46 anni.

O jogo das identidades como fator de mobilização político-eleitoral nas campanhas de Dilma Rousseff e Rosalba Ciarlini em 2010

Starting from the premise that we live in the society of spectacle, as proclaimed by Guy Debbord, and, in this context, the media feeds itself off of this spectacularization and constructs a culture of images and production of goods, providing templates from which the subject can identify himself/herself as being male or female, successful or unsuccessful, powerful or powerless. In other words, the culture conveyed by the media produces material for the creation of identities through which individuals insert and recognize themselves in contemporary society. Observing the election campaigns, we can see clearly that this profusion of identities is fairly explored in the advertising propaganda used by the candidates, particularly in the propaganda broadcasted on the Free Electoral Time on TV. Instigated by the explicit relation between the media and politics within the society of the spectacle, this study aims to investigate the main identities that emerge in the discursive practices of the media in the election campaigns of 2010 for president of the Republic and governor of the State of Rio Grande do Norte that had as protagonists the candidates at that moment Dilma Rousseff (PT) for president and Rosalba Ciarline (DEM) for governor. To do so, we based ourselves on the theory of Bakhtin Circle, which considers the statement as a unit of verbal communication and conceives language as a dialogical phenomena and a discursive practice and also in the conceptions of dialogical relationships, social voices and chronotope formulated by the previous mentioned theory. Still in the theoretical field, we have established an interconnection with the theories coming from the Cultural Studies (Hall, Woodward) about the identity, which conceives it as multiple, fragmented, non-fixed, so that, the subject assumes different identities, not always coherent, at different times, depending on the context in which they are approached. The research is situated in the frames of Applied Linguistics, which considers language as the center of its studies and settles on the border of an open number of areas of knowledge expanding its possibilities of investigation by means of the interdisciplinary. Our corpus consists in 20 electoral propaganda videos aired on TV during the Free Election Time in 2010 campaign; among these, 14 videos are Dilma Rousseff s propaganda and 06 videos are Rosalba Ciarline s propaganda. We seek for the purpose of the analysis to identify the identities which emerge from the discourses about the candidates in propaganda videos broadcasted in the referred campaign, as well as realize the dialogical relations established in these discourses and even if the identity construction of these subjects is located in the same axiological axis. The corpus analysis revealed that the multiple cultural identities of the candidates campaigning emerge in the discourses circulating in the electoral propaganda aired on TV such as: the identities of pioneer woman, competent, sensitive, mother, grandmother, religious. And, yet, those are changeable as the electoral demands, in other words, the need to obtain support and votes, outline a fluid identity construction about the candidate to the position in question

Nuovi orientamenti di carriera e qualità del lavoro. Un contributo di ricerca

Il presente contributo prende le mosse dalla consapevolezza che i modelli lineari tradizionali sulle carriere (Super, 1980) hanno lasciato il passo a concettualizzazioni più complesse e non lineari (Cohen, Duberley & Mallon, 2004; Pryor & Bright, 2007; Richardson, 2002), argomento tra l’altro approfondito operando una disanima delle principali transizioni di carriera e dei fenomeni psicosociali ad esse correlate (Schlossberg, Waters & Goodman, 1995). Vengono affrontati temi attuali quali quelli della Globalizzazione riflessiva (Beck, 1999), della complessità e delle Flessibilità (Sennett, 1998) e se ne mette in luce le interrelazioni con il fenomeno delle carriere, ed in particolare delle dinamiche che ne hanno modificato progressivamente e radicalmente la natura nel corso degli ultimi trent’anni (Hall, 1976, 1996). È stato approfondito il tema dei nuovi percorsi di carriera, con particolare attenzione ai costrutti teorici della Protean Career (Carriera Versatile) e della Boundaryless Career (Carriera senza confini). Sono stati condotti due studi, mediante il metodo dell’inchiesta, proponendo dei questionari autosomministrabili a due gruppi di lavoratori dipendenti. La selezione degli strumenti da inserire nel protocollo, e quindi delle ipotesi da verificare è stata operata in funzione delle caratteristiche intrinseche dei due gruppi coinvolti, cercando comunque di valorizzare sempre il ruolo dei nuovi orientamenti di carriera all’interno del disegno di ricerca. Lo studio 1 è stato condotto su un gruppo di 540 lavoratori dipendenti provenienti da Sardegna e Sicilia. Facendo riferimento agli studi tradizionali sull’insicurezza lavorativa (Sverke & Hellgren, 2002), si è cercato di valutare l’eventuale effetto moderante dei nuovi orientamenti di carriera (Briscoe, Hall & Frautschy De Muth, 2006) circa gli effetti dell’insicurezza su benessere psicofisico (Goldberg, 1972) e coinvolgimento lavorativo (Schaufeli, Bakker & Salanova, 2006; Scaufeli, Salanova, Gonzalez-Romá & Bakker, 2002). I risultati hanno mostrato alcuni effetti parziali, ma d’altro canto è emerso che i medesimi orientamenti di carriera risultano significativamente e direttamente associati a variabili quali l’Autoefficacia, la Proattività, il benessere e il Coinvolgimento. Lo studio 2, riguardante un gruppo di 79 neolaureati di Palermo e provincia al primo inserimento lavorativo, è stato condotto nell’arco di 8 mesi con tre rilevazioni dati. In questo caso si è cercato di evidenziare eventuali effetti causali longitudinali degli orientamenti di carriera sulle variabili dipendenti già incluse nello studio 2. Le ipotesi espresse hanno trovato soltanto parziale conferma nei risultati.

La carriera degli attori italiani di prosa dalla scena allo schermo (1909-1916)

Most actors of the Italian silent cinema in the early 1910s have a theatrical training. Some of them are already asserted or famous actors (like Cesare Dondini, Ermete Novelli, Ermete Zacconi, Giovanni Grasso) who are invited “to pose” for the cinema following their reputation, according to a strategy of an aesthetic and cultural legitimacy launched in 1909 by film d'art of the Pathé Consortium. I think it is the proverbial readiness and strength of the stage Italian actors that create a decisive contribution to the rapid development of the national cinema industry, despite its serious structural deficiencies, from the protoindustrialized phase (1909) to the golden age of divismo (starting in 1913), until the first signs of decadence (1919), and the so-called “fall” of the UCI production and distribution system. This is the main topic of the thesis: an investigation on the Italian stage actors engaged in the film industry (“from stage to screen” as the Italian title says, but in a “post-Vardac” approach) through many different sources: periodicals, memories, personal and business letters, and also contracts, found in several archive funds. A specific chapter is dedicated to the artistic career of Febo Mari (1881-1939), real name Alfredo Rodriguez, witch is a time-sample symptomatic of deep ties established between the growing film publishing and the Italian theatrical production system in the 1910s. The Mari debut in cinema and his ascent toward screen “divo” status coincides with the parable that leads from emergence to decadence of divismo in Italy.

SwarmPS: Rapid, semi-automated single particle selection software

Single particle analysis (SPA) coupled with high-resolution electron cryo-microscopy is emerging as a powerful technique for the structure determination of membrane protein complexes and soluble macromolecular assemblies. Current estimates suggest that ∼104–105 particle projections are required to attain a 3 Å resolution 3D reconstruction (symmetry dependent). Selecting this number of molecular projections differing in size, shape and symmetry is a rate-limiting step for the automation of 3D image reconstruction. Here, we present SwarmPS, a feature rich GUI based software package to manage large scale, semi-automated particle picking projects. The software provides cross-correlation and edge-detection algorithms. Algorithm-specific parameters are transparently and automatically determined through user interaction with the image, rather than by trial and error. Other features include multiple image handling (∼102), local and global particle selection options, interactive image freezing, automatic particle centering, and full manual override to correct false positives and negatives. SwarmPS is user friendly, flexible, extensible, fast, and capable of exporting boxed out projection images, or particle coordinates, compatible with downstream image processing suites.

Automatic particle picking of biological molecules imaged by electron microscopy

One of the next great challenges of cell biology is the determination of the enormous number of protein structures encoded in genomes. In recent years, advances in electron cryo-microscopy and high-resolution single particle analysis have developed to the point where they now provide a methodology for high resolution structure determination. Using this approach, images of randomly oriented single particles are aligned computationally to reconstruct 3-D structures of proteins and even whole viruses. One of the limiting factors in obtaining high-resolution reconstructions is obtaining a large enough representative dataset ($>100,000$ particles). Traditionally particles have been manually picked which is an extremely labour intensive process. The problem is made especially difficult by the low signal-to-noise ratio of the images. This paper describes the development of automatic particle picking software, which has been tested with both negatively stained and cryo-electron micrographs. This algorithm has been shown to be capable of selecting most of the particles, with few false positives. Further work will involve extending the software to detect differently shaped and oriented particles.

Paralelização em CUDA/GLSL do algoritmo SIFT para reconhecimento de íris

Neste trabalho é estudada a viabilidade de uma implementação em paralelo do algoritmo scale invariant feature transform (SIFT) para identificação de íris. Para a implementação do código foi utilizada a arquitetura para computação paralela compute unified device architecture (CUDA) e a linguagem OpenGL shading language (GLSL). O algoritmo foi testado utilizando três bases de dados de olhos e íris, o noisy visible wavelength iris image Database (UBIRIS), Michal-Libor e CASIA. Testes foram feitos para determinar o tempo de processamento para verificação da presença ou não de um indivíduo em um banco de dados, determinar a eficiência dos algoritmos de busca implementados em GLSL e CUDA e buscar valores de calibração que melhoram o posicionamento e a distribuição dos pontos-chave na região de interesse (íris) e a robustez do programa final.

On the Assumption of Bivariate Normality in Selection Models: A Copula Approach Applied to Estimating HIV Prevalence

Background: Heckman-type selection models have been used to control HIV prevalence estimates for selection bias when participation in HIV testing and HIV status are associated after controlling for observed variables. These models typically rely on the strong assumption that the error terms in the participation and the outcome equations that comprise the model are distributed as bivariate normal.
Methods: We introduce a novel approach for relaxing the bivariate normality assumption in selection models using copula functions. We apply this method to estimating HIV prevalence and new confidence intervals (CI) in the 2007 Zambia Demographic and Health Survey (DHS) by using interviewer identity as the selection variable that predicts participation (consent to test) but not the outcome (HIV status).
Results: We show in a simulation study that selection models can generate biased results when the bivariate normality assumption is violated. In the 2007 Zambia DHS, HIV prevalence estimates are similar irrespective of the structure of the association assumed between participation and outcome. For men, we estimate a population HIV prevalence of 21% (95% CI = 16%–25%) compared with 12% (11%–13%) among those who consented to be tested; for women, the corresponding figures are 19% (13%–24%) and 16% (15%–17%).
Conclusions: Copula approaches to Heckman-type selection models are a useful addition to the methodological toolkit of HIV epidemiology and of epidemiology in general. We develop the use of this approach to systematically evaluate the robustness of HIV prevalence estimates based on selection models, both empirically and in a simulation study.

Adjusting HIV Prevalence Estimates for Non-participation: an Application to Demographic Surveillance

Introduction: HIV testing is a cornerstone of efforts to combat the HIV epidemic, and testing conducted as part of surveillance provides invaluable data on the spread of infection and the effectiveness of campaigns to reduce the transmission of HIV. However, participation in HIV testing can be low, and if respondents systematically select not to be tested because they know or suspect they are HIV positive (and fear disclosure), standard approaches to deal with missing data will fail to remove selection bias. We implemented Heckman-type selection models, which can be used to adjust for missing data that are not missing at random, and established the extent of selection bias in a population-based HIV survey in an HIV hyperendemic community in rural South Africa.

Methods: We used data from a population-based HIV survey carried out in 2009 in rural KwaZulu-Natal, South Africa. In this survey, 5565 women (35%) and 2567 men (27%) provided blood for an HIV test. We accounted for missing data using interviewer identity as a selection variable which predicted consent to HIV testing but was unlikely to be independently associated with HIV status. Our approach involved using this selection variable to examine the HIV status of residents who would ordinarily refuse to test, except that they were allocated a persuasive interviewer. Our copula model allows for flexibility when modelling the dependence structure between HIV survey participation and HIV status.

Results: For women, our selection model generated an HIV prevalence estimate of 33% (95% CI 27–40) for all people eligible to consent to HIV testing in the survey. This estimate is higher than the estimate of 24% generated when only information from respondents who participated in testing is used in the analysis, and the estimate of 27% when imputation analysis is used to predict missing data on HIV status. For men, we found an HIV prevalence of 25% (95% CI 15–35) using the selection model, compared to 16% among those who participated in testing, and 18% estimated with imputation. We provide new confidence intervals that correct for the fact that the relationship between testing and HIV status is unknown and requires estimation.

Conclusions: We confirm the feasibility and value of adopting selection models to account for missing data in population-based HIV surveys and surveillance systems. Elements of survey design, such as interviewer identity, present the opportunity to adopt this approach in routine applications. Where non-participation is high, true confidence intervals are much wider than those generated by standard approaches to dealing with missing data suggest.
