Isometric Force Matching Asymmetries Depend on the Position of the Left Hand Regardless of Handedness
No full textSeveral studies highlighted differences in behavioral performance between the two hands, either due to hand dominance or to specialization of the brain hemisphere. In a previous study, right-handed individuals performed a bimanual isometric force-matching task with the arms in different configurations. There we found that the accuracy of the performance depended on the position of the left hand. Matching performance was worse when the left hand was in the lower position, regardless the symmetry of the arm configurations. In the present study, we tested the hypothesis that this effect is related to handedness, i.e., that in both right- and left-handed individuals the performance depends on the position of the non-dominant hand. Left-handed and age-matched right-handed participants were required to apply simultaneously the same amount of force in the upward direction, with the arms in symmetric or asymmetric configurations. No visual feedback of limb positions was provided. We found that for both groups the absolute and the signed (bias) difference of force between the sides depended on the position of the left hand. Thus, this role of the left arm was not determined by handedness, but likely by the specialization of the brain hemisphere. However, handedness influenced the performance: left-handers had a higher absolute error than right-handers in almost all conditions. No main effect of the left hand position was found for the variable error, but left-handers in most configurations had higher variable error when the left hand was in the lower position
Le vedute di Pietro Fabris e il collezionismo britannico a Napoli durante il Grand Tour: tempi, modi e formule di un successo
Full text linkIl lavoro di ricerca condotto nel triennio dottorale è incentrato sul pittore anglo-napoletano Pietro Fabris, attivo a Napoli nella seconda metà del XVIII secolo come autore di vedute e scene di genere. Protetto dall'ambasciatore britannico William Hamilton, Fabris entrò in contatto con i Grand Tourists e con la Corte borbonica, riscuotendo largo consenso a Napoli e in Inghilterra. Esaminando l'evoluzione del fenomeno del Grand Tour a Napoli dal XVII al XVIII secolo, vengono delineate le ragioni e le dinamiche che hanno decretato il successo dei dipinti di Pietro Fabris presso i viaggiatori stranieri, in particolare britannici, mentre attraverso l'analisi di documenti inediti, rinvenuti nell'Archivio Storico del Banco di Napoli e nell'Archivio di Stato di Napoli, sono state ricostruite la vicenda biografica e le relazioni del pittore con acquirenti e collezionisti. La tesi è dunque punto di partenza per studi futuri sul pittore e sul collezionismo di vedute napoletane
Ragweed pollen travels long distance
No full textAltough Ambrosia artemisiifolia is considered a non relevant allergenic pollen in Italy, since it's not indigenous to the country, we found that 37% of our atopic patients are indeed sensitized to this aeroallergen. This could be due either to cross-reactivity with other plants of the Compositae family or to a primary sensitization to A. artemisiifolia pollen, brought to Italy by winds from Eastern European countries

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
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
Non solo reliquie : traduzioni di materiali dal suburbio alla città e la spoliazione dei cimiteri : spunti per un'inchiesta
No full textThe present study aims to verify whether sometimes the translation of the holy bodies – a practice in which Paschal
I was an undisputed protagonist – may have been associated with the movement of some materials and connected
with phenomena of spoliation of sanctuaries and cemeteries. The development of the theme is not easy and clashes
with some difficulties: the complexity of the relics removal’ phenomenon from the original tombs; the general difficulty
to refer cemeterial marbles present in the various churches of Rome to specific suburban sites and to chronologically
frame their displacement; the general lack of knowledge on the procedures of the spoliation, widely documented in the
the early Middle Ages to the centuries of the modern age.
As a starting point, an attempt has been made to trace the
origin of the ‘historical’ inscriptions, i.e. those linked to clearly
recognisable original burial contexts and then dispersed
in various urban churches
Pasquale I e gli orizzonti culturali del papato nei secoli VIII e IX. Riflessioni sulla documentazione papiracea
No full textThe article aims at reflecting on the cultural references of papal documentary production at the time of Paschal I, more in
general during the eighth and ninth centuries, starting from sources hitherto scarcely exploited by historians: the original
documents written on papyrus. The analysis of materials, structures, contents, and writers allows not only to better
understand some writing practices at the basis of the Liber Pontificalis, but also to grasp more clearly the Mediterranean
horizon within which documents and writers operated. It was in a context of intense exchanges between East and West – especially in the seventh century but also during the eighth and ninth centuries – that papal officers and scriniarii in particular acquired their cultural physiognomy: this is well demonstrated by the formation of the so-called “curial writing”, part of a wider Mediterranean cultural koinè. The pontificate of Paschal I fits well within such frame: without putting aside the relationships with Carolingian rulers, both administrative structures and religious affairs mantained contact with the East
