Un Test Breve di Intelligenza: il K-BIT
No full textConsiderando che in ambito evolutivo la valutazione del funzionamento intellettivo costituisce un criterio base di ogni assessment cognitivo, è sempre più sentita l’esigenza di strumenti che forniscano una valutazione accurata, completa e al contempo veloce dell’intelligenza. Il Kaufman Brief Intelligence Test (K-BIT) (Kaufman & Kaufman, 1990) è un test breve di intelligenza che fornisce indici di QI Verbale, Non Verbale e Composito. Il presente contributo fornisce una valutazione preliminare dell’adattamento del K-BIT su un campione italiano (820 partecipanti, 6-14 anni). Metodo: Vengono forniti i dati preliminari riferiti ai valori normativi per il campione italiano, suddivisi per fasce d’età, e una stima dei coefficienti di correlazione con la WISC-R. Una riflessione particolare è riferita all’analisi degli indici di difficoltà per i diversi subtest (Vocabolario Espressivo, Definizioni, Matrici) e alla valutazione della tipologia di errori rilevati nel subtest di Vocabolario Espressivo. Risultati: Si è osservata una distribuzione degli indici di QI omogenea rispetto a quella della standardizzazione originale ed è emersa una buona validità concorrente con la WISC-R. L’analisi degli errori al Vocabolario Espressivo è stata discussa in riferimento alla frequenza della parola nel lessico italiano e alle caratteristiche dell’immagine. Conclusioni: Il K-BIT si configura come un buono strumento per attività di screening e valutazioni rapide del funzionamento intellettivo. La standardizzazione italiana completa è in corso di realizzazione

Surface transport of DOC acts as a trophic link among Mediterranean sub-basins
No full textLateral advection affects the spatial distribution of dissolved substances in the ocean but very few studies, so far, have been devoted to describe and quantify its impact on the distribution of dissolved organic carbon (DOC) which, in oligotrophic environments, accounts for the largest fraction of chemical energy. In this contribution, using an integrated approach, we explore the importance of surface advection on carbon dynamics in the Western Mediterranean Sea, where strong inter-basin differences in primary production do exist. Detailed information on the surface circulation, derived from high-resolution model simulations, is combined with the analysis of spatially resolved, accurate DOC vertical profiles, repeated over time. Our data show that surface circulation plays a crucial role in regulating DOC concentrations and distributions in the Tyrrhenian Sea and that horizontal transport of DOC into the Tyrrhenian Sea is of the same order of magnitude as in-situ DOC production. Our study addresses this process for the first time in the Mediterranean Sea, whose small size allows for fast, inter-basin transfer times which, in turn, favors the preservation of the DOC stock produced elsewhere. We highlight that this mechanism may be important also in other regions of the oceans, where surface advection may set up a sort of compensation among regions with different trophic regimes, thus smoothing trophic gradients. We posit that understanding these transport processes is a crucial and preliminary step to understand and quantify all the other processes (biological, chemical, geological) that influence DOC distribution on a variety of timescales
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
