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
Call me by your name: towards an authority data control shared between archives and libraries
No full textAn important and not often addressed topic – considering the issues opened by cross-disciplinary projects – is the shared control of authority records, or better authority metadata, extended to other documentary and cultural heritage sciences. This paper will examine the potential opened by multi-dimensional and networked logic in the representation of entities in the form of data towards which the document communities are converging. This approach is even more valid if we consider the users’ point of view, presently forced to jump from one information environment to another, and confront
different names, forms, and attributes for the same entities. The core entities to work on are persons, corporate bodies, places, chronological contexts, events, and qualifying their relationships. After a brief resume of archival description’s peculiarity,
the paper highlights the updated standards available, mostly IFLA-LRM and RiC, precious documents to start from and stimulate an active collaboration. To facilitate the sharing, control, and enrichment of authority data in the form of RDF assertions, librarians and archivists may follow several pathways: matching the existing conceptual models, converging on a shared data playground like Wikidata, and developing foundational meta-ontology
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
Motivations to volunteer and satisfaction among mentors in the Mentor-UP program | LA MOTIVAZIONE E LA SODDISFAZIONE DEI MENTOR CHE PARTECIPANO AL PROGRAMMA MENTOR-UP
No full textWhereas the positive impact of mentoring programs on at-risk children (mentee) has been shown in previous research in the field, limited studies have focused on young adult volunteers (mentor) and their motivations to volunteer. The aims of the current study are (i) to highlight mentors' initial motivations; (ii) to test whether the initial motivations are reflected in the final benefits of their participation in the «Mentor- UP» program; and (iii) to test the associations between such motivations-benefits, the satisfaction with the mentoring experience, and the intention to engage in civic activities in the future. 62 mentors (university students) took part to the program and completed a series of questionnaires at the beginning and at the end of the program. Results revealed that, at the beginning of the program, mentors mainly expected to increase their knowledge and to express their values through the participation (motivations). At the end of the program, they reported the highest benefits in knowledge and carrier functions. Moreover, mentors reporting high levels of knowledge function were more satisfied with the program and more likely to engage in civic activities in the future as well as mentors reporting high levels of carrier benefit. In conclusion, these results should be taken into account by researchers and educational practitioners in the field of mentoring and Service-learning. © 2020 Societa Editrice il Mulino.

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
