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
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
Management of Research Data in ETD Systems
Full text linkPurpose
To establish the research data management practices in institutions which have ETD programmes. These may include the systems in place (software and hardware), and the integration of data and text.
Design/methodology/approach
Along with a review of the literature the authors carried out a brief survey of existing practices in the management of the raw data on which a thesis/dissertation is based. A questionnaire was sent to the members of the Networked Digital Library of Theses and Dissertations (NDLTD) and a number of other institutions.
Findings
Sixty percent of the respondents indicated that their institutions have research data management centres/services. Only in one institution is there a relationship between the ETD programme and the data management centre/service. In this instance, ETDs were previously housed on the Academic Computing Services servers. Most of the institutions have no policy on the stewardship of raw data of a thesis/dissertation, and raw data is only stored if provided by the author along with the full text. Other forms of data pose challenges to institutions, and they are investigating options for including other data such as artwork, datasets and recordings, that form part of the submission.
Practical implications The paper will be a source of information to institutions considering embarking on the management of research data, especially that research data on which a thesis/dissertation is based.
Originality/value
The work draws attention to the need to collect research data of long term value. Such data may for example be utilised for the transfer of knowledge and skills by using postgraduate students to train less experienced students, using the archived/stored data without duplicating costly experiments, or for multiple projects based on the same or expanded datasets
Knowledge Management (KM) in Higher Education: The Role of Librarians/Information Professionals

In the US, mergers are happening at small liberal colleges.
In China, Australia & the UK, mergers have happened in big universities.

Sometimes the position of University Librarian (Director of Libraries) is eliminated.
New organisation structures have been developed. But
The blended model is said to have failed in research universities in the US. (A. Foster, 2008)

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
IR and OA Initiatives in Africa
No full textEarly IR and OA initiatives in Africa began in 1998, before the term OA was current.
•
Rhodes University (RU) in South Africa mounted its first digital thesis on the World Wide Web in 1998; it became the first institution in Africa to do so. Other grey literature also gathered.
•
RU, like many institutions in South Africa, has developed an OA repository, using EPrintsoftware, containing other digital knowledge products.
•
The Database of African Theses and Dissertations (DATAD) programme of the Association of African Universities (AAU), which was designed to improve management and access to African scholarly work, was a precursor to the development of OA repositories by institutions which participated in the programme
