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
New routes to crystallographic data publication
No full textA full-day workshop organised by Simon Coles (Chair) and Mike Hursthouse (University of Southampton, UK), John Huffman (Indiana University, USA), Peter Strickland (IUCr), Frank Allen (CCDC) and John Westbrook (PDB).This event is aimed at initiating a wide-ranging debate on new routes for the effective and efficient dissemination of the ever-increasing volume of crystallographic raw and results data, as a complementary approach to the conventional route of publication of scientific journal articles. The workshop is concerned with:
a) raising awareness of innovative procedures under development for data dissemination and the new opportunities they can provide for publication,
b) enabling groups working in the area to compare approaches and develop a unified strategy for data management, including publication and preservation and
c) inviting participation in this topic from interested parties.
The methods and approaches to publishing scientific research output (i.e. making it available to the public domain) are currently undergoing a seed-change. New initiatives include such processes as author self deposition of reprints in Institutional Repositories, author-pays open access journals and open discussion of results in Wiki’s or Blogs, and these are gathering momentum. On one hand this movement has been slow to appear in some disciplines (eg Chemistry), yet is widely accepted and routine in others (eg Physics and Biology). The field of crystallography is a data-rich subject that supports a vast number of conventional journal articles across a very broad range of disciplines, and seeds of change are very much evident here. Recent developments include:
1. The IUCr prepared an extensive report to the Science and Technology Committee in 2004 regarding electronic publishing, data and open access (http://www.iucr.org/iucr/stcttee04.html) and a position paper (http://www.iucr.org/iucr/gicsi/positionpaper.html).
2. IUCr were awarded three rounds of funding to enable the content of their journals provided by UK authors to be made publicly available through Open Access (JISC funded) and examine the culture changes and impact on their business model.
3. From Jan 2008 Acta Cryst Section E will become Open Access (Author pays).
4. Numerous successful projects aimed at authors self-publishing data (eCrystals, ReciprocalNet, Crystallography Open Database) have been created.
The indications are therefore that the time is now right to explore these new routes to publishing, with a particular emphasis on the crystallographic raw and results data, as an alternative to conventional journal articles. This is especially relevant in the light of a recognised data deluge (F.H. Allen, Crystallogr. Reviews, 2004, 10, 3-15), where it is commonly recognised that approximately only 20% of small-molecule crystal structures determined as a result of publicly funded research reach the public domain. This is a direct consequence of the way in which data is traditionally published.
The principal contributions to this workshop would be from those responsible for recent developments and innovations in the area and are outlined below. The primary aims of the workshop will be to:
1. Raise awareness in the crystallographic community of these new innovations and the opportunities they offer for data publication, and invite participation.
2. Enable projects and interested parties working in the area to compare approaches and develop a unified way forward for the future of data publication.
The topics to be covered as sessions of the workshop include:
1. Self publication by an author: Institutional data repositories (eg eCrystals project), Open databases (e.g. COD) and consortia (eg ReciprocalNet)
2. Author pays Open Access (eg Acta Cryst E, Chemistry Central)
3. Interoperability and linking between data sources
4. Interactions between data sources and data centres, publishers & learned societies
5. Data discovery and linking to journal articles and other sources of electronic information openly available
6. Support, training, raising awareness and advocacy for data publication
7. Future sustainability and preservation of openly available data, -policy and finance.
8. Ownership of data

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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
