Google Scholar: potentially good for users of academic information
No full textUse of the Google search engine is commonplace amongst all sectors of the academic community. The development of the specialist Google Scholar search service will benefit the academic community in bringing to their attention content more relevant to their needs. The vast number of Web sites containing potentially relevant information requires a search engine ranging over many millions of Web sites but with the ability to target very specific types of information. The Google Scholar service has the potential to grow if it develops close contacts with both providers and users of academic information. Use of Google Scholar will benefit the authors and managers of open access content, but there are opportunities for all types of academic content providers in the way Google Scholar is set up. Google Scholar will face competition and have to keep pace with user expectations and technological developments

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
How can there be open access to journal articles?
No full textThe possibility of open access to journal literature has generated considerable discussion in the academic, publishing and library communities. The discussion has largely centred not on the desirability of open access in principle but upon its practicability and its effect upon the traditional journal publication system. This article will examine points made in the public discussion of the two major routes to open access outlined in the Budapest Open Access Initiative (BOAI), author self-archiving in academic repositories and the publication of journals using new toll-free economic models. Issues both for and against open access have been raised by authors, by publishers and by librarians, and a realistic approach to the feasibility of open access is important. The conclusion reached will be that open access to journal literature is feasible through either BOAI strategy but that more investigation is needed of both the positive and the negative messages received from stakeholders with as much experimentation of different models as possible
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
