La dinamica della legislazione elettorale nella Russia post-Sovietica: le elezioni libere tra forma e sostanza
Full text linkNegli ultimi decenni in Russia si è potuto osservare un continuo declino delle istituzioni rappresentative ed elettorali. Tale tendenza – legata da un lato allo svuotamento del contenuto democratico del meccanismo elettorale e dall’altro allo scivolamento graduale dell’ordinamento verso una forma di presidenzialismo sempre più personalistico – ha portato molti a ripensare in termini meno ottimistici il processo di democratizzazione nel Paese. Oggi, infatti, come mai prima, è divenuto chiaro quanto il modello politico-istituzionale della Russia si discosti dal modello occidentale di democrazia rappresentativa pluralista
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
An empirical method for modelling and simulating some complex macroscopic phenomena by cellular automata
No full textNovel parallel computing models sometime represent a valid alternative to standard differential equation methods inmodelling complex phenomena. In particular, Cellular Automata (CA) provide such an alternative approach for some complexnatural systems, whose behaviour can be described in terms of local interactions of their constituent parts. This paper illustratesan empirical method applied with interesting results in modelling and simulating some complex macroscopic phenomena.While classical CA are based upon elementary automata, with few states and a simple transition function, in order to dealwith macroscopic phenomena it is often necessary to allow a large number of different states a more complicated transition.The notion of substate is introduced in the macroscopic case for decomposing the state of the cell. The values associatedto substates can change in time either due to interactions among substates inside the cell (internal transformations) or to localinteractions among neighbouring cells.The internal transformations are treated in a way similar to ordinary difference equations.The local interactions among cells can be often treated according to an algorithm for the minimisation of differences, whichdescribes a tendency of conserved quantities to reach an equilibrium distribution.A large class of complex macroscopic phenomena seem to satisfy the applicability conditions of such an empirical method;some of them are briefly reviewed
On line e su carta. "La Repubblica" e "Repubblica.it": un confronto
No full textIl giornale on line è il più recente tra i mezzi d’informazione. Nato dalla nuova tecnologia telematica della rete, in breve tempo emerge come nuovo possibile mezzo di informazione, modificando in parte i contenuti del giornale tradizionale, da cui trae origine. Il giornale elettronico inizialmente si è riferito prevalentemente ad un pubblico giovane, mentre quello cartaceo ad un pubblico più adulto. Sembra plausibile, quindi, ipotizzare una certa differenza nel tipo di informazione veicolata dai due tipi di giornale. Lo studio, presentato in questo articolo, pone a confronto la prima pagina del giornale ‘la Repubblica’ nella versione cartacea ed elettronican analizzati per 120 giorni raggruppati in 18 settimane per un totale di 240 pagine e 3269 titoli. E’ stata usata la tecnica dell’analisi del contenuto e i risultati hanno evidenziato che il giornale on line sta affrancandosi da quello cartaceo e si sta evolvendo verso una differenziazione che porta anche a contenuti propri.. Il giornale on line approfondisce di meno i contenuti rispetto al giornale cartaceo, tanto che si può dire che il giornale on line ha una funzione pedagogica più sfumata rispetto al cartaceo: il giornale on line lascia al lettore il compito di approfondire, riflettere e commentare
