Relationship between accuracy and speed in the Raven’s coloured progressive matrices test: Normative data for Italian children aged 5-6 years
Full text linkThe Raven’s Coloured Matrices (CPM) is one of the most used tests for assessing fluid intelligence in children. Although the speed factor is considered important for the measurement of this construct, normative data for speed are not available for the CPM test, and the speed contribution on the test performance is not known in the literature. To help fill these gaps, we provide the CPM Accuracy and Speed norms, and data on the relationship between the two measures, concerning a sample of 468 Italian children aged 5-6 years. A negative correlation emerged between accuracy and speed for the Ab and B Sets of the test, which include the most complex problems. The association in Set B (the most difficult) between a decrease in accuracy and an increase in speed suggests the prevalence of random responses, advising the exclusion of this Set from the computation of the total score in the considered ages. Comparisons between three groups of children (inaccurate and fast; inaccurate and slow; accurate and slow) indicate that the poor accuracy of fast children may be due to an impulsive approach to the task. This pattern of results calls into question the practice of evaluating the test performance taking into account only the accuracy factor
Il percorso dell'insufficienza renale acuta in un presidio ospedaliero organizzato per intensità di cure
No full textIl modello per intensità di cure prevede la valutazione del paziente secondo parametri che, nel complesso, riescono a definire in modo esatto il livello e il modulo a cui assegnare lo stesso. Le cure ospedaliere, nel caso dell’insufficienza renale acuta (IRA), devono essere impostate innanzitutto con l’intento di prevenire o risolvere sia l’ipovolemia che l’ischemia renale e la somministrazione di liquidi deve tenere conto del complesso emodinamico e della risposta renale al carico idrico. Lo scopo del presente lavoro è quello di elaborare il percorso dell’IRA nel presidio ospedaliero Sant’Andrea di Massa Marittima, facente parte della Asl 9 della provincia di Grosseto. Allo stesso tempo, però, si mira anche ad assicurare un’ottimale gestione del paziente adulto con IRA (residente nel territorio delle Colline Metallifere) a partire dalle necessità che quest’ultimo può sviluppare al proprio domicilio
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
