Remote Hardware-In-the-Loop Measurement System for Electrolyser Characterization
Full text linkThe installation of facilities replicating the real-world condition is often required for carrying out meaningful tests on new devices and for collecting data with the aim to create realistic device model. However, these facilities require huge investments, as well as areas where they can be properly installed. In this paper, we present a test infrastruc- ture exploiting the concept of Remote Power Hardware-In-the-Loop (RPHIL), applied for characterizing the performances of a 8kW Pro- ton Exchange Membrane (PEM) electrolyser installed at the Hanze University of Applied Sciences in Groningen (The Netherlands). The electrolyser is subjected to dierent test conditions imposed both lo- cally and remotely. The results show that this measurement procedure is eective and can open new perspectives in the way to share and exploit the existing research infrastructure in Europe
Virtù e società perfette: una questione pedagogica di lungo periodo
No full textForme di immaginazione di realtà sociali, politiche ed economiche pensate come alternative rispetto alla realtà storica in cui vengono elaborate; disegni di società perfette, proiettate in una dimensione spazio-temporale indefinita, le utopie vengono assunte in questo contributo come privilegiata fonte storica. La tensione al miglioramento sociale è però anche, intrinsecamente, questione pedagogica, le società perfette infatti richiedono l’esistenza di uomini altrettanto perfetti capaci di far esistere e sussistere le stesse società. La felicità individuata come stato sociale ottimale è il risultato di un’educazione alla virtù a sua volta testimonianza di una subordinazione della felicità del singolo a quella della collettività. Attraverso l’analisi di alcune utopie moderne si cercherà di evidenziare, nel reciproco rimando tra politeia e paideia, le virtù necessarie alla perfetta felicità
«Society is a hole»: la virtù della disobbedienza civile e incivile nelle controculture della seconda metà del Novecento
No full textIl rapporto tra le diverse generazioni si è sempre definito in termini conflittuali, a maggior ragione nel Novecento, un secolo non solo “breve” (secondo la celebre definizione di Hobsbawm), ma anche “accelerato” (riprendendo il sottotitolo del romanzo Generazione X di Coupland), in cui la ricerca di modalità espressive autonome da quella dei genitori ha portato a ridurre sempre più l’arco cronologico in cui si inscrive una generazione. In questa prospettiva il giovane, qualunque giovane in qualunque momento del secondo Novecento, diventa il perfetto folks devil e suscita quel fenomeno ben descritto da Stanley Cohen, proprio partendo dalle sottoculture dei Mod e dei Rocker britannici, che conosciamo come panico morale (moral panic). L’intervento punta ad evidenziare come nel Novecento le sottoculture e controculture abbiano definito nuovi canoni etici ed estetici che disobbedivano al comune sentire e che progressivamente sono rientrati (in parte o in tutto) nell’alveo della cultura dominante in un susseguirsi di conflitti più o meno espliciti. La disobbedienza, quindi, diventa un modo di affermazione individuale e generazionale, uno strumento per affermare un passaggio di consegne generazionale e in questi termini, una virtù
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
