    Per il Pozzoserrato: opere sacre

    No full text
    Il pittore neerlandese Lodewijk Toeput naturalizzatosi a Venezia e poi più a lungo residente a Treviso è noto soprattutto per la sua dedizione al genere “paesistico”. Partendo da questa constatazione si propone il catalogo delle opere più trascurate, quelle “di figura” di destinazione sacra, alcune delle quali inedite e attribuite per la prima volta. Oltre ad accertare l’impegno in questo ambito del Toeput si distinguono altre personalità a lui vicine protagoniste nella Terraferma veneziana, in particolare nella Marca Trevigiana, della pittura post tridentina. Si osservano le declinazioni del lascito tintorettesco e veronesiano che lasciò la sua impronta in Toeput

    Kriegskarte 1798-1805: Il Ducato di Venezia nella carta di Anton von Zach/Das Herzogtum Venedig auf der Karte Antons von Zach

    This scholarly edition of the Anton von Zach map will be published in 2005, to mark the 200th anniversary of its completion in 1805: an invaluable source of information about the configuration and life of an area of about forty thousand square kilometres which corresponds, with partial historical border differences, to the present Italian regions of the Veneto and Friuli. The Topographisch-geometrische Kriegskarte von dem Herzogthum Venedig (Topographic-geometrical military map of the Duchy of Venice), now conserved in the Kriegsarchiv of Vienna, was produced for the Austrian General Staff by a group of topographers coordinated by Staff Officer Anton von Zach. The edition includes all 120 of the sheets at the original scale (1: 28.800 ca.), a transcription of the 922 manuscript military description papers (Militärische Beschreibungen) together with an Italian translation, a German/Italian glossary of about four hundred technical terms and an index of the thousands of place names mentioned. The work as a whole constitutes an essential source of knowledge about the history and geography of North-East Italy in the troubled transition phase connecting the Republic of Venice to the period of Hapsburg domination. Five years of research and a further two years of editing have led to a publication on profitable purchase terms which is indispensable in several fields. Scientific and professional spheres have acquired new references for historians and geographers, for cartographers and topographers, for town planners and landscape experts. Institutions at European, national and local levels, especially regions, provinces and municipalities, now have new means of identifying changes and environmental and territorial layering over a period of two centuries. And the community in general is enriched because the work constitutes documentary evidence of places, symbols and names that now re-emerge as distinctive components of our common heritage in the construction of Europe

    La galleria pittorica di Santa Maria della Vittoria Nuova, una ricostruzione virtuale

    No full text
    Si presta attenzione, dapprima, alla chiesa di fondazione scaligera di Santa Maria della Vittoria e San Giorgio (Santa Maria della Vittoria Vecchia) e alle sue pitture, in particolare alla Madonna con il Bambino di Nicola Giolfino ora alla Gemäldegalerie di Berlino. Si prendono in esame le opere di Girolamo Dai Libri, Francesco Morone, Liberale da Verona ora al Museo di Castelvecchio. Attraverso i disegni e gli appunti di Giovanni Battista Cavalcaselle, riprodotti nell’occasione, e alla sua documentazione degli affreschi che il grande conoscitore poteva ancora esaminare in una porzione superstite della chiesa, si ricostruisce la particolare congiuntura creatasi in questa chiesa nei primi decenni del Cinquecento, di particolare importanza per la pittura veronese del momento. È ricostruito il contesto in cui si collocava il Compianto di Cristo prima della deposizione nel sepolcro, rappresentativa opera giovanile di Paolo Veronese. Si definisce l’intervento in più riprese nella cappella di Sant’Anna di Francesco Perezzoli detto il Ferrarino. Nonostante sia superstite un’unica opera, si congettura quale fosse lo stile delle opere perdute realizzate nel corso degli anni ottanta del Seicento, quando il pittore veronese svolge i suoi aggiornamenti a Milano, Bologna e Roma

    Le opere d’arte già in San Francesco di Paola: dalla chiesa al museo e ritorno

    Si ricostruisce il contesto dei dipinti d’altare pubblicati nella chiesa dei Minimi veronesi a partire dallo scorcio del Cinquecento fino alle soglie del 1630, anno del gran contagio. Le opere di Santo Creara, Orazio Farinati, Claudio Ridolfi, Dario Pozzo e Pasquale Ottino affrontano temi comuni ad altre chiese dei Minimi, secondo le istanze di un’arte post-tridentina e una sensibilità propria della congregazione fedele allo spirito del fondatore, il taumaturgo sostenitore del quarto voto di quaresima perpetua. Particolare rilievo ha la verifica sulla qualità della tela del Cristo deposto nel sepolcro di Ottino originariamente collocata nel coro e celebrata dagli storiografi veronesi. È stata identificata di recente presso la cattedrale di San Vito a Praga, ma si valuta nell’occasione una copia antica. Si ricostruisce nel suo contenuto iconografico il ciclo perduto delle storie del santo fondatore che vide all’opera a fine Seicento un gruppo di comprimari della pittura veronese caratterizzati da un’esperienza bolognese. Si identifica presso la chiesa la cappella dedicata alla Madonna di Loreto, che ripete per la prima volta in ordine di tempo a Verona il modello della Santa Casa. È ricostruito, infine, lo spettacolare altare maggiore di Orazio Marinali grazie al progetto disegnativo di quello della chiesa di San Giuliano a Vicenza tuttora in loco. Su base documentaria di stabilisce l’indubbia precedenza di quello della chiesa dei Minimi veronesi

    Herd Level Yield Gap Analysis in a Local Scale Dairy Farming System: A Practical Approach to Discriminate between Nutritional and Other Constraining Factors

    This study performed a yield gap analysis to help farmers understand whether their constraints were mainly due to nutritional factors or management and health issues. Twenty-nine farms were periodically evaluated. Milk yield (MY), dry matter intake (DMI), total mixed ration (TMR) composition and homogeneity index (HI), TMR digestibility, income over feed cost (IOFC), and MY summer–winter ratio (SWR) were collected. Farms were divided and compared according to the average annual MY: Low (L), Medium (M) and High (H), characterised by 36.7 kg/head/day. An ANOVA mixed model and a stepwise regression to assess the relationship between nutritional variables and MY were run. H farms showed higher IOFC (p < 0.001), DMI (p = 0.006), DDM (p < 0.001), digestible crude protein (DCP, p = 0.019), HI (p = 0.09), SWR (p = 0.041) and lower HI coefficient of variation (p = 0.04). The conversion of DDM into milk was higher in H and M farms. Stepwise regression for MY selected DDM and CP (R2 = 0.716, p < 0.05). M farms were mainly constrained by nutritional factors, whereas L farms were also affected by other factors such as those related to management and health

    MeSH term explosion and author rank improve expert recommendations

    Information overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank

    Going Beyond Counting First Authors in Author Co-citation Analysis

    No full text
    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    "Closing the R&D Gap, Evaluating the Sources of R&D Spending"

    No full text
    Both spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
