La biblioteconomia comparata e l’apporto di Peter Johan Lor: una strategia di ricerca per l’analisi di influenze, divergenze e consonanze
Get PDFThe paper presents Peter Johan Lor’s book, International and comparative librarianship: concepts and methods for global studies (Berlin; Boston: De Gruyter Saur, 2019). As a result of a long research, the book shows the origins and the evolution of international and comparative librarianship as fields of study and research; it explains professional literature development on the subject; it deals with methodological aspects in terms of approaches, techniques and tools of comparison intended as a research strategy to analyze influences, divergences and consonances between different library contexts. Lor’s book is an opportunity for theoretical study but also a working tool, thanks also to the numerous examples that concern different geographic areas of the world and types of library as well as a variety of themes, functions and services. For its systematic approach, completeness and accuracy it is the most updated reference point for comparative studies, especially for library contexts, such as the Italian one, that are still too poor in reflections and real applications.Il contributo presenta il volume di Peter Johan Lor, International and comparative librarianship: concepts and methods for global studies (Berlin; Boston: De Gruyter Saur, 2019). Il libro, frutto di un lavoro decennale dello studioso, traccia le origini e l’evoluzione della biblioteconomia internazionale e della biblioteconomia comparata come campi di studio e ricerca, ricostruisce lo sviluppo della letteratura professionale in materia, affronta gli aspetti metodologici in termini di approcci, tecniche e strumenti della comparazione intesa come strategia di ricerca funzionale ad analizzare influenze, divergenze e consonanze tra contesti bibliotecari diversi. Il testo di Lor è occasione di approfondimento teorico e pratico strumento di lavoro, grazie anche ai numerosi esempi che riguardano aree geografiche del mondo e tipologie di biblioteca diverse oltre a una grande varietà di temi, funzioni e servizi. Per sistematicità, completezza e rigore costituisce il più aggiornato punto di riferimento per gli studi comparati, soprattutto per contesti biblioteconomici, come quello italiano, ancora troppo poveri di riflessioni sul tema e di applicazioni concrete
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
Democracy, information, and libraries in a time of post-truth discourse
No full text
Purpose
To serve their clients in a time of post-truth discourse and fake news, librarians need to understand the post-truth phenomenon. The purpose of this paper is to examine it, what is being done in response to it, and specifically what libraries can do.
Design/methodology/approach
Recent literature on the post-truth phenomenon was examined. Traditional assumptions about the role of libraries in promoting democracy were questioned and an alternative view was put forward. Libraries’ responses to the post-truth phenomenon were examined and critically discussed.
Findings
Traditional assumptions about the role of libraries and information and democracy are outdated. The susceptibility of people to false beliefs and the persistence of these beliefs in spite of corrective information, is the product of many factors, including the evolving media ecosystem and psychosocial processes which are the subject of ongoing empirical research. It not primarily an information or knowledge deficit, hence there are no simple antidotes to fake news. Libraries need to rethink their responses.
Research limitations/implications
The paper deals with very recent developments and relies heavily on informal online resources.
Practical implications
Relevant library activities are examined and suggestions are made for developing appropriate library responses.
Originality/value
At the time of writing this was the first attempt in the library management literature to engage in a systematic and thoughtful manner with the literature on the post-truth phenomenon.
