Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
La competenza digitale e le disuguaglianze socio-scolastiche degli studenti. Un’analisi con test standardizzato nella scuola secondaria di I e II grado
Get PDFThe development of digital competence among youth is one of the main focuses of European and Italian policies, but only few international studies measure this construct in a statistically rigorous manner. This article analyses data collected up to 2024 using the first standardized performance test available in Italy, which has been developed following the European framework DigComp. The dataset consists of 6,646 records from students ranging from grade 6 to 13 who completed the test between 2021 and 2024, thanks to the participation of at least one of their teachers in the Benessere Digitale-Scuole project. The article examines the performance of the sample across different school levels and grades, as well as individual, family, and school factors influencing digital competence. Results show that digital competence increases with grade level, with communication being the most familiar area to students, while information & literacy appears to be the least mastered. Significant differences are observed on the basis of students’ school level, migratory background, and parental education. Additionally, digital competence shows a positive correlation with self-reported marks, especially in Italian, especially for students from disadvantaged socio-school contexts
Un’opportunità o un disincentivo al lavoro? L’impatto eterogeneo del Reddito di Cittadinanza sulle chances occupazionali: uno studio di caso
No full textThe Citizenship Income (Reddito di Cittadinanza, RdC) consists of the provision of a monetary subsidy to supplement the income of poor families, conditional on adherence to paths of social and work inclusion. The aim of this article is to present one of the first impact evaluations of the RdC on the employment outcomes of beneficiaries in the Sardinia Region who were in a state of unemployment at the time they began to receive the benefit, between April 2019 and June 2021. The empirical analysis is based on two large databases taken from administrative sources, provided by the Labor and Training Information System. Their integration makes it possible to reconstruct the socio-personal characteristics and the working careers of both the recipients of the RdC and non-beneficiaries who have had at least one contact with the Employment Centers (CPI). The analytical strategy is based on the innovative combination of statistical matching techniques (entropy balancing), binomial logistic regression, survival analysis, and meta-analysis techniques. The results indicate that, overall, having received the RdC reduced the subsequent employment chances almost negligibly for those who were unemployed when they began to receive the economic benefit. However, the heterogeneity analysis suggests that perceiving the RdC contributed to decreasing employment chances for those categories that were in a position of traditional weakness in relation to the labor market in Sardinia and more generally in Italy
