Il movimento cattolico umbro fra intransigentismo,conciliatorismo e modernismo
No full textIl saggio ripercorre la storia del movimento cattolico in Umbria partendo, all’indomani dell’Unità, dall’attività del prete perugino don Umberto Benigni, che dopo aver manifestato orientamenti cristiano-sociali diverrà uno dei maggiori animatori della lotta contro ogni forma di modernismo e contro ogni tendenza liberale all’interno del mondo cattolico, per poi verificare la forte presenza del movimento conciliatorista, da legare all’esistenza nella regione di una fitta rete di opere pie, che alimentarono nel laicato una diffusa volontà di partecipare, attraverso gli enti territoriali locali, alla gestione del ricco “patrimonio dei poveri”, fino a sottolineare l’impatto della lettera enciclica Rerum Novarum, che non va ricercata tanto nella somma innumerevole di iniziative assunte, anche se queste non mancarono, quanto piuttosto in una mobilitazione delle coscienze che riuscì almeno ad avvicinare Chiesa e vita. Con il nuovo secolo l’enciclica leonina rappresentò per i democratici cristiani della regione un obiettivo da realizzare e la premessa per superare la pretesa di svolgere un'azione sociale senza scelte politiche. La stagione del modernismo, assai significativa in Umbria, verrà affrontata attraverso lo studio dell’atteggiamento di mons. Michele Faloci Pulignani, appartenente a quella schiera di ecclesiastici che contrastarono quella corrente religiosa-politica-culturale, ma da una posizione dialogante, aliena da quegli eccessi che spesso condussero altri oppositori a utilizzare nella lotta metodi inquisitori, sostenuti dalla delazione, dal sospetto o peggio dalla calunnia
Innovative Radiating Systems for Train Localization in Interference Conditions
No full textThe design of innovative radiating systems based on the metamaterial technology for GNSS (Global Navigation Satellite System) applications in radio frequency (RF) interference conditions is proposed. To this aim, firstly two typical adaptive array techniques (i.e., nulling and beam-forming) are discussed and tradeed off. Secondly, FRPA (Fixed Radiation Pattern Antenna) and CRPA (Controlled Radiation Pattern Antenna) phased array configurations of miniaturized patch antennas are studied by means of electromagnetic commercial tools and phased array optimization algorithms. This process leads to the identification of a phased array design. Benefits and drawbacks for GNSS applications are highlighted. Finally, the design of the phased array is applied to a GNSS user receiver in a navigation realistic environment. Simulation results are obtained in a realistic scenario for railway applications, comprising of a GNSS satellite constellation, a GNSS user receiver (i.e., on-board train equipment) running along a track in Western Australia, and a constellation of interfering satellites. Navigation service performances (i.e., user location accuracy and service availability) are computed taking into account the adaptive array radiation pattern in two different modes (i.e., FRPA or CRPA) and band-limited white noise interference
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
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
