Mihi... amplectenda est Frontonis imitatio: Frontone tra Ausonio e Simmaco
Full text linkIl lavoro considera le modalità di ricezione del corpus epistolare frontoniano nella Tarda Antichità e in particolare in Ausonio e Simmaco. Negli ultimi decenni del IV secolo la figura di Marco Aurelio gode di grande fortuna in quanto incarna un ideale di potere positivo da riprendere e emulare. In questo contesto l’appropriazione della produzione del suo amato maestro Frontone non si limita alla ripresa di termini arcaici ma agisce a livello più profondo, influenzando la concezione che Ausonio e Simmaco hanno della prassi epistolare nonché la loro la strategia di autorappresentazione
Rileggendo l’ultimo carteggio tra Ausonio e Paolino di Nola: qualche spunto di riflessione
No full textIl contributo propone una riconsiderazione unitaria dell’ultimo carteggio tra Ausonio e il suo antico allievo Paolino alla luce della bibliografia più recente. L’analisi di momenti significativi delle epist. 21 e 22 (Green) di Ausonio e del carme 10 di Paolino non solo aggiunge qualche ulteriore tessera ovidiana (trist. 4, 7, 1-4) e oraziana (epist. 1, 14, 19-20 e epist. 1, 1, 39-40) ai modelli poetici di Paolino, ma mette in luce che le ricercate strategie argomentative e letterarie dei due interlocutori, basate su un differente rapporto tra creazione letteraria e dato di realtà, travalicano la
dimensione personale e riflettono il confronto in seno alla società aristocratica del tempo tra fedeltà assoluta ai valori della tradizione (Ausonio) e possibilità di recuperare quei valori a una radicale prospettiva cristiana di vita e di letteratura (Paolino)
Drone swarms in fire suppression activities: A conceptual framework
No full textThe recent huge technological development of unmanned aerial vehicles (UAVs) can provide breakthrough means of fighting wildland fires. We propose an innovative forest firefighting system based on the use of a swarm of hundreds of UAVs able to generate a continuous flow of extinguishing liquid on the fire front, simulating the effect of rain. Automatic battery replacement and extinguishing liquid refill ensure the continuity of the action. We illustrate the validity of the approach in Mediterranean scrub first computing the critical water flow rate according to the main factors involved in the evolution of a fire, then estimating the number of linear meters of active fire front that can be extinguished depending on the number of drones available and the amount of extinguishing fluid carried. A fire propagation cellular automata model is also employed to study the evolution of the fire. Simulation results suggest that the proposed system can provide the flow of water required to fight low-intensity and limited extent fires or to support current forest firefighting techniques
Scheduling Landing and Payload Switch of Unmanned Aerial Vehicles on a Single Automatic Platform
No full textWe focus on the problem of optimally managing a set of unmanned aerial vehicles performing given missions that require to land on an automatic platform, unmount the currently-carried payload, and take off with another payload to complete mission objectives. Such a problem often arises when swarms of drones cooperate to complete monitoring applications or other tasks requiring an efficient schedule of landings and payload switches in a resource-constrained environment. First, the problem is formulated as a mixed-integer linear programming one, which, however, may be complex to be solved for a large number of drones. Thus, we also propose a heuristic algorithm able to find suboptimal solutions with a reduced computational effort. Preliminary simulation results are reported and discussed

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
