UNICORE summit 2011 : proceedings, 7 - 8 July 2011, Torun, Poland
Full text linkWhen the foundations of UNICORE were laid in the late 90’s of the 20th century the "ancestors" intended to create a uniform interface to computing resources for a (small) number of computing centres. Today - in the era of eSciences and large distributed eInfrastructures - UNICORE has become one of the most innovative and major middlewares in Grid Computing serving users around the world. The UNICORE Summit is a unique event for users, developers, researchers, administrators and service providers to meet. They hear the latest news, share their experiences, present recent and intended developments, get new ideas for projects, find partners and discuss the future of UNICORE. The Summit has been held every year since it started in 2005. The 2011 Summit took place in Torun on July 7 and 8. Torun is an ancient city in Northern Poland picturesquely located on the Vistula river. At about the same time when UNICORE was founded the medieval part of Torun was designated a World heritage by the UNESCO. The event was opened with an invited talk by Abdulrahman Azab from the University of Stavanger on the usage of R and UNICORE for medical research. In the following, 16 technical contributions gave more insights to various development and usage aspects. Additionally, posters were presented by the authors in a poster session on Friday. In the second invited talk Piotr Bala from Warsaw reported on the usage of UNICORE in the polish national Grid initiative PL-Grid. A unique feature of the Summit were the lively plenary discussions. The topics focused on the future ways UNICORE should go, with subjects like "UNICORE and Clouds" or "UNICORE and Portals". We would like to thank all contributors for their presentations and papers as well as the organisers of the UNICORE Summit 2011 in Torun for their excellent work. We are sure every participant will keep this wonderful event in mind. More information about the UNICORE summit series can be found at http://www.unicore.eu/summit/. We are looking forward to the next UNICORE Summit 2012
Adopting GLUE 2.0 for an Interoperable Grid Monitoring System
No full textInteroperability is an important issue, especially in Grid infrastructures that use multiple, inhomogeneous Grid middlewares. Monitoring such heterogeneous scenarios requires interoperability of different information services. The approach taken bases on an integration proxy together with a standardized information model. This proxy functions as a bridge between the information models used in different Grid information services by using GLUE 2.0 as the homogeneous common model. This paper outlines the chosen architecture and details the experiences gained with the GLUE 2.0 schema

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
UNICORE Summit 2013
Full text linkThe UNICORE Grid technology provides a seamless, secure, and intuitive access to distributed Grid resources. UNICORE is a full-grown and well-tested Grid middleware system, which today is used in daily production worldwide. Beyond this production usage, the UNICORE technology serves as a solid basis in many European and International projects. In order to foster these ongoing developments, UNICORE is available as open source under BSD licence at http://www.unicore.eu. The UNICORE Summit is a unique opportunity for Grid users, developers, administrators, researchers, and service providers to meet and share experiences, present past and future developments, and get new ideas for prosperous future work and collaborations. The UNICORE Summit 2013, the nineth in its series, has been held as a satellite event at the ISC Conference in Leipzig, Germany, on 18 June 2013. The proceedings at hand include a selection of 9 papers that show the spectrum of where and how UNICORE is used and further extended, especially with respect to data management and application support
