No full textInner Loaded Annular Piezoelectric Sensor
No full textIn this work the possibility of realizing a novel accelerometer by using a ring-shaped piezoceramic, loaded by a seismic mass in its inner space, has been investigated. Measurements were carried out by using two different electrode configurations in order to reveal both symmetrical and antisymmetrical modes. The experimental results show that this structure allows an increase of the sensitivity, by increasing the seismic mass, without sacrificing the useful bandwidth, as happens in traditional accelerometers. Moreover, for the symmetrical modes, this sensor exhibits planar isotropy, i.e., it shows the same response for any mechanical excitation in the plane
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
Le fondazioni dei frati predicatori in Sicilia tra XIII e XVIII secolo: un primo bilancio storiografico
No full textThe historiographical literature dedicated to the architecture of the Friar Preachers in Sicily, if one excludes the few studies on the complexes in Palermo, which are anyhow focussed on the churches only, is still substantially limited to the sporadic studies by local scholars or members of the Order on the history of the Dominicans in Sicily. The aim of our research, therefore, was to outline a general framework that could serve as a stepping stone for further research. It was first of all necessary to carry out a census of all the Dominican architectural complexes in Sicily, in order to determine the overall dimensions of the phenomenon and its chronological and territorial articulation, and then match it with the unfolding of historical events within the Order and the Kingdom’s socio-political context. Therefore, four main periods were identified with clear distinctive features: 1) from 1220 to 1250; 2) the 150-year period between the second half of the thirteenth century and the whole of the fourteenth century; 3) between the first decade of the fifteenth century and the 1580’s; and 4) between the seventeenth and the first half of the eighteenth centuries. Starting with this cognitive basis, the following analytical phase focussed on identifying the original architectural layout of the monastery complexes and any shared settlement strategies - in relation to the different periods of their construction and the different social forces involved (municipality or feudal nobility).
In drawing an overall balance, it can be concluded that the spread of the Friar Preachers in Sicily, rather slow in the long initial phase spanning the thirteenth and fourteenth centuries, was a macroscopic phenomenon substantially linked to the fifteenth and sixteenth centuries. Moreover, the Order’s settlement took place following the logic of a widespread presence of small communities throughout the Kingdom, rather than through the construction of large complexes in major cities. The only exception to this logic was the Dominican community in Palermo
