10041 Abstracts Collection – Perspectives Workshop: Digital Social Networks
Get PDFFrom 24.01.2010 to 29.01.2010, the Dagstuhl Seminar 10041 ``Perspectives Workshop: Digital Social Networks'' was held in Schloss Dagstuhl ~--~ Leibniz Center for Informatics.
During the seminar, several participants presented their current
research, and ongoing work and open problems were discussed. Abstracts of
the presentations given during the seminar as well as abstracts of
seminar results and ideas are put together in this paper. The first section
describes the seminar topics and goals in general.

Biorhythms in the life cycle of myxococcus xanthus Myxococcus Xanthus UCM 10041 and Polyangium Cellulosum UCM 10043

З’ясовано, що частка життєздатних клітин та здатність міксобактерій утворювати плодові тіла циклічно коливаються. Частка клітин, здатних утворювати колонії, обернено пропорційна кількості утворюваних плодових тіл.Установлено наличие биологических ритмов в жизнедеятельности культур миксобактерий М. xanthus UCM 10041 и P. cellulosum UCM 10043. Показано, что относительное число жизнеспособных клеток и способность миксобактерий образовывать плодовые тела циклично колеблется. Долевая часть клеток, способных образовывать колонии, обратно пропорциональна количеству формируемых плодовых тел.Biological rhythms in the vital activity of myxobacteria strains Myxococcus xanthus UCM 10041 and Polyangium cellulosum UCM 10043 has been found. Part of viable cells and an ability of myxobacteria to form fruiting bodies are fluctuating cyclically. The part of viable cells is reverse proportional to the ability to form fruiting bodie
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
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
10041 Manifesto – Perspectives Workshop: Digital Social Media
No full textThis manifesto explains and stresses the importance of “digital social media”, "social software" and "social computing". In particular, it makes the claim that we need a better
understanding of how this mix of enabling technology, social behaviour and market practises is challenging our socio-economical and political systems, and puts forward an action plan for the areas of education, fundamental research and applied research, to address these challenges.
The goal of this manifesto is to raise awareness for digital social media and to stress the need for research, research funding, and education in a field so far under-represented in public research funding programmes and in education. This manifesto does not cover all aspects of digital social media, or provide a comprehensive treatment of their socio-economical impact. Such issues are beyond the scope of this manifesto.
This manifesto is an outcome of a Perspective Workshop held from the 25th to 29th of January 2010 at the research centre Schloss Dagstuhl. The workshop brought together scientists and practitioners from academia and industry, across the fields of social sciences
and computer science
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
