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
Scientific, Technical and Economic Committee for Fisheries (STECF). Review of Guidelines for the National Programs and Technical Reports under the Data Collection Framework. Report of the Subgroup on Research Needs (SGECA/SGRN 09-03) Joint Subgroup on Economic Affairs (SGECA) and on Research Needs (SGRN) of the Scientific, Technical and Economic Committee for Fisheries (STECF)
Full text linkArticles 6(1) and 7(2) of Council Regulation (EC) No 199/2008 state that the evaluation of both NP proposals and TRs should be carried out by STECF. Therefore, the guidelines and templates should also facilitate SGRN�s evaluation of Member States� compliance with the DCF. SGRN received a mandate to review these guidelines and templates in its July 2009 meeting (SGRN-09-02), and proposed a new structure for both NP proposals and TRs, and a totally revised version of the Standard Tables. The RCMs subsequently provided an in-depth review of the revised tables. The purpose of the SGRN/ECA-09-03 meeting (Ispra, 19-21 October 2009) to review of NP and TR guidelines was to finalise the templates and guidelines, starting from the work done in SGRN in July 2009 and the comments made by the four RCMs (RCM North Sea and Eastern Arctic, RCM North Atlantic, RCM Baltic, RCM Mediterranean and Black Sea).JRC.G.4 - Maritime affair

Scientific, Technical and Economic Committee for Fisheries (STECF) Opinion by Written Procedure - Review of Scientific Advice for 2010 Advice on Stocks in the Baltic Sea (SGECA/SGRST- 09-01)
Full text linkThe STECF SGRST/ECA -09-01 met in Carlottenlund (Denmark) to review the scientific advice given by the ICES on Baltic Sea stocks and fisheries. The scientific advice on the stocks and fisheries in the Baltic Sea in 2010 was evaluated and endorsed by the Scientific, Technical and Economic Committee for Fisheries (STECF) by written procedure in June 2009 on request oif the European Commission.JRC.G.4 - Maritime affair
ICES 2009 - Report of the planning on commercial catches, discards and biological sampling (PGCCDBS)
No full textPGCCDBS is the ICES forum for planning and co-ordination of collec-tion of data for stock assessment purposes; it coordinates and initiates the develop-ment of methods and adopts sampling standards and guidelines. Many activities in this group are closely linked to the activities of the DCR, and DG MARE is a member of PGCCDBS to ensure coordination with the DCR activities. Stock assessment re-quires data covering the total removal from the fish stocks and the PG serves as a forum for coordination with non-EU member countries where appropriate. Since 2007, Mediterranean scientists have organised a Mediterranean Planning Group for Methodological Development (PGMED) to deal with specific sampling issues of this area. Although organised in an autonomous group, it was agreed among all scientists that the contact and cooperation between the Mediterranean area the ICES area should be promoted and maintained. The link between the two planning groups is maintained through: (i) the inclusion of each group's report as an annex of the oth-er; (ii) the organisation of parallel meetings; (iii) the organisation of joint plenary ses-sions for generic issues, and (iv) the organisation of joint workshops. Last year�s recommendations and intersession work were reviewed. Most of them were concluded with success and those not concluded gave raise to developments carried out during this year. The intersession work was related to mixed species land-ings, and minimum sampling protocols for sampling length and for age calibration. An age readers forum is about to be established, and would be used as a �one stop shop� for all those involved in age reading. ICES Cooperative Research Reports should be written on the current status of age determination of a species (or group of species) after exchanges and workshops have been conducted. A Common Open Source Tool (COST) for assessing the accuracy of the biological data and parameters estimates collected for stock assessment purpose, and a WebGR project to develop a set of web services to support the organization and data analysis of calibration work-shops are among the methodological achievements discussed in the report. The Group reviewed reports from relevant Expert Groups with respect to recom-mendations addressed to PGCCDBS. As feedback mechanism from data users (mainly Assessment WGs) to the PG, 'data contact persons' were proposed with a set of tasks to report on data problems etc. PGCCDBS will act as an advisory group on the further development of InterCatch. InterCatch is a web-based system to ease the data handling for assessment purpose. PGCCDBS were strongly of the opinion that the improvement of InterCatch needs to be addressed with urgency. Recent changes in data collection (e.g. through the revised EU Data Collection Framework) were reviewed and the need for workshops was defined.JRC.G.4 - Maritime affair
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
