San Martino di Serravalle e San Bartolomeo de Castelàz. Due chiese di Valtellina: scavi e ricerche
No full textLe chiese di San Bartolomeo de Castelàz e San Martino di Serravalle, sorte sulla via di accesso alla contea di Bormio, in Valtellina, hanno avuto un importante ruolo in momenti storici definiti. Gli studi archeologici, storici e artistici condotti su questi edifici – illustrati nelle pagine di questo volume – permettono di ricostruire il succedersi degli avvenimenti che in epoche diverse hanno avvicinato queste valli alla storia europea. Così gli affreschi di San Martino e i materiali archeologici provenienti dallo scavo divengono illuminanti per comprendere l’importanza della maglia viaria che univa la pianura ai paesi transalpini, contribuendo con il transito di popolani e aristocratici, mercanti e pellegrini a creare una cultura artistica comune. Di contro, le indagini archeologiche effettuate nelle vicinanze della chiesa di San Bartolomeo hanno messo in luce un insediamento, distrutto da un incendio, i cui resti appaiono di grande interesse per ricostruire lo stile di vita delle genti del luogo. L’analisi dello scavo all’interno e accanto alla chiesa di San Bartolomeo chiarisce come questo edificio fu costruito dopo la prima distruzione delle mura di Serravalle, a cavallo tra XIII e XIV secolo. I cicli pittorici, che ancora oggi ne decorano l’interno, testimoniano un momento più recente della vita della vallata in età postmedievale. Ne risulta un quadro interessante dal punto di vista sia sociale sia artistico, che testimonia come queste valli, apparentemente isolate dalla grande storia, abbiano di fatto agito come snodo vitale nella intermediazione tra culture

No full textUndesired effects of steroids during pregnancy
No full textAntenatal corticosteroid administration for enhancing fetal lung maturity can be expected to induce negative maternal and fetal side-effects. Maternal short-term effects after multiple courses of corticosteroids are an increase of infections and a higher incidence of endometritis and chorionamnionitis in patients with premature rupture of membranes. A single dose of corticosteroid induces an increase in the count of maternal white blood cells and metabolic effects such as the augmentation of amino acid concentration and of fasting glucose levels in maternal plasma. Negative fetal effects of antenatal corticosteroids are a reduction of fetal body and breathing movements and a reduction of fetal heart rate variation, without any changes in Doppler waveform patterns of fetoplacental vessels. It has been suggested that a multiple course of corticosteroids antenatally might induce negative effects on fetal intrauterine growth and on neonatal birth weight. In addition, multiple courses are associated with an increased risk of early-onset neonatal sepsis
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

No full textVariations 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
