¿Debemos tomarnos en serio la desintermediación?
Full text linkBibliographic review about citation analysis of research publications as a method for study information needs and use by research users of libraries. Once compared the local citation analysis studies from the works of potential users of a library against the citation studies from the bibliography in the international or national data bases, the review takes account of the different document sources for the local citation analysis studies. As an indirect method for user and information use studies is an efficient unobtrusive method, that allow to collect information at a level of detail not available through other methodsThe implications of disintermediation for librarians and information specialists (intermediaries) can be experienced as either a threat or a challenge, depending on how the issue is viewed. The different ways in which information specialist can react to disintermediation are discussed. Although most of these are viable, none addresses all implications of desintermediation. A holistic approach to desintermediation is therefore proposed, in which the situation of the intermediary is viewed within the wider society. The following aspects should be analyzed with regard to their effect on desintermediation: changes in the society at large, the availability of information services. The specific end-users and the information specialist involved should also be analyzed. With this approach it will be found that the effects of desintermediation will vary according to the particular situations. To prepare information specialists for the effects of desintermediation, their training should also be adapted accordingly.

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
Understanding and exploiting idiosyncrasy in the use of ICT devices such as tablets : setting the background
Full text linkWhen using information communication technology (ICT) devices it is easy to be trapped by purely the purpose of their design, how they are marketed, product reviews and noting, or even copying, the behaviour of the younger, Net Generation. The purpose of this column is to argue for encouraging all to contribute to deepening our understanding of fully exploiting technology. This includes encouraging people who may be less techno-savvy but with a richer life-world and life-experience to share their use of devices such as tablets, and to allow all to benefit from the idiosyncrasy in use that should be aimed at a life-fit with personality, learning style, preferences, etc., and widening information spaces and information horizons. The column is written against the background of research from information behaviour, and the learning sciences (especially andragogics). There are many reasons to explore more than the obvious ways in which ICT devices such as tablets can be used, and for encouraging a spectrum of users to share the idiosyncrasies in
their use thereof. Library and information (LIS) services should move from merely teaching people information literacy and ICT skills to creating grounds for sharing practices and experiences in using
devices such as tablets. The focus should move to exploiting the benefit of exploring idiosyncrasies in ICT use and how to encourage people to reflect their life-world and life-experience in their use of ICT
devices such as tablets to widen their (and our) information spaces and information horizons. Although much has been published on ICT in the library and information science literature and more recently in relation to the Net Generation, the author is not aware of
publications exploiting idiosyncrasy and the value that can be added by considering the life-world and life-experience of people in their choices in using ICT devices such as tablets. This paper sets the
background for further reflection.http://www.emeraldinsight.com/0737-8831.htmdm201
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
