Casi controversi in materia di diritto delle successioni
Full text linkLa presente Opera segna la conclusione del progetto “Casi controversi in materia di diritto delle successioni”, finanziato dall’Università di Verona nell’ambito del “Bando di Ateneo per la ricerca di base 2015”, ma iniziato – attraverso l’organizzazione di un ciclo di convegni, conferenze e seminari – già nel 2011, in concomitanza con l’attivazione a Verona del corso di “Diritto delle successioni”. Il progetto ha visto la partecipazione di un gruppo di ricerca veronese e di gruppi di ricerca di Francia (responsabile Anne-Marie Leroyer), Germania (responsabile Christian Baldus), Austria (responsabile Johannes Michael Rainer), Spagna (responsabile Esther Arroyo Amayuelas), Brasile (responsabile Elena de Carvalho Gomes) e Cina (responsabile Qing Lu), nonché di accademici italiani di varia provenienza, al fine fondamentalmente di elaborare proposte per una rivisitazione del diritto delle successioni, soprattutto (ma non solo) italiano. Alla luce non tanto del gran numero di scritti raccolti, quanto piuttosto della necessità che il diritto delle successioni sia spinto a evolversi con cautela, integrando esso – più di altri settori del diritto privato – un complesso macchinario composto da tanti ingranaggi tra loro strettamente collegati, alcuni dei quali può auspicarsi che siano ammodernati, ma solo dopo averne approfonditamente valutato le ripercussioni sistematiche (ciò che è particolarmente importante per il diritto delle successioni italiano, che, a differenza di quelli di altri Paesi, non ha costituito oggetto – quantomeno non direttamente – di riforme organiche in tempi recenti), si è scelto di articolare l’Opera – che deve peraltro intendersi fondamentalmente unitaria – in due volumi, dedicati il primo alle “Esperienze italiane” e il secondo alle “Esperienze straniere”, così da sottolineare già tramite tale scelta la prudenza con cui le suggestioni provenienti dai diritti stranieri dovrebbero essere sempre valutate prima di un loro eventuale recepimento da parte del diritto italiano

No full textEnvironmental controls of epilithic diatom depth-distribution in an oligotrophic lake characterized by marked water-level fluctuations
No full textThe depth-distribution of epilithic diatoms in a carbonate meromictic lake (south-eastern Alps), characterized by marked water-level fluctuations, was investigated. Fixed stations were placed along a depth-profile at intervals of 2-3 m and sampled throughout the year using scuba diving. Diatom analysis included quantification of living cells (biovolume calculations) and the estimation of fucoxanthin concentration, which, coupled with the analysis of digested material, permitted taxonomic determination at specific or subspecific level. Multivariate analyses indicated the following variables to be significant: water-level fluctuations, photosynthetically active radiation, silica and nitrates. Diatoms had distinct depth-distributions. Quantification of densities, biovolumes and Chl a, and physiological (senescence index, fucoxanthin), functional (photosynthetic efficiency), and community structure (diversity) parameters allowed the definition of three depth-distribution zones (shallow, mid-depth and deep). The different diatom communities in these zones were confirmed by ANOSIM (analysis of similarity). The shallow, mid-depth, and deep zone were characterized by disturbance due to water-level fluctuations, high stability with favourable growth conditions and severe light limitation, respectively. Community composition and diversity depth-distribution features remained relatively stable throughout the year, while marked changes in benthic diatom biovolumes were modulated by competition for light with phytoplankton. Fucoxanthin was strongly correlated with epilithic diatom biovolumes. The results indicate that depth-distribution patterns should be considered when performing lake diatom biodiversity inventories and integrity evaluations because water-level fluctuations are likely to increase in many lakes due to increased withdrawal of water and climate change in the future. © 2009 British Phycological Society
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
