The anatomical sculpture in the second half of XVIIth century: the artistic career of Giovan Battista Manfredini
No full textSome researches have been started within a collaboration project between the University of Modena and the University of Padua and about the anatomist Antonio Scarpa (at the conference of UNIVERSEUM - June 2011 http://www.musei.unipd.it/eventi/doc/universeum/Book_Abstracts.pdf), who graduated at the University of Padua and had his first teaching appointment in Anatomy and surgery in 1772 at the University of Modena, to provide an in-depth overview on how in the second half of XVIIIth century the progress of the study and of the teaching of Obstetrics determined the realization of a considerable “suppellex obstetricia”, that is to say obstetric models in wax or clay for educational purposes. It was fundamental the activity of Giovan Battista Manfredini (1742-1789), a bolognese sculptor who had been very active in the production of anatomical models: his activity as a sculptor was recognized by his contemporaries who in 1785 appointed him effective member of the Accademia Clementina, in the Class of Anatomical Sculptors, not less important than his Bolognese forerunners, Giovanni Manzolini and Anna Maria Morandi Manzolini.The researches aim at first at comparing the documentation on Manfredini with the works that have been attributed to him also according to stylistic comparisons, starting from colored wax and clay anatomical models that have been attributed to him, with specific in-depth researches for those that at present are preserved at the University of Padua (Department of Woman and Child Health – Obstetrical Clinic) and at the University of Modena (Anatomical Museums) in comparison with those preserved in Bologna (Museum of Palazzo Poggi) and Rome (National Museum of Medical History of Art), trying to define those stylistic and fabrication peculiar features that characterize his anatomical production.At second to re-discover and recognize other models created by Manfredini, not only for other Italian towns, like those of Mantua, but also for other European countries, like Poland or Russia, for which it is necessary to deepen the researches and, however, testify the close connection of the expertise of Manfredini with the progress of the studies of Obstetrics in Europ
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
The phosphorylation state of DARPP-32, a third messenger for dopamine, is regulated by in vivo pharmacological treatments
No full textIt has been recently proposed that DARPP-32 participates, as third messenger, in the mediation of effects induced by dopamine at the cellular level. DARPP-32 is indeed localized almost exclusively on dopaminoceptive neurons bearing the D1 receptor subtype and it is phosphorylated by cAMP-dependent protein kinase. In its phospho-form, DARPP-32 acts as an inhibitor of protein phosphatase-1. In vivo pharmacological treatment with selective D1 agonists and antagonists induces changes in the phosphorylation state of DARPP-32 that can be correlated to changes in cAMP, mediated in turn by D1 and D2 receptors. These data demonstrate that the measurement of the phosphorylation state of DARPP-32 with the back-phosphorylation assay can represent a useful biochemical tool to gain further insight into the sequence of events elicited by specific dopaminergic drugs in vivo
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
