Algorithms for Wireless Communication (Dagstuhl Seminar 14051)
No full textThis report documents the talks and discussions of Dagstuhl Seminar 14051 "Algorithms for Wireless Communication". The presented talks represent a wide spectrum of work on wireless networks. The topic of wireless communication continues to grow in many domains, new applications and deployments of wireless networks in a variety of contexts are being reported. A key focus of the talks and discussions presented here is to discuss models for wireless networks as well as algorithmic results and real world deployments
ISO 14051: A new era for MFCA implementation and research
No full textMaterial flow cost accounting (MFCA) is a tool designed to encourage eco-efficiency in organizations by focusing on a reduction in use of materials and related improvements in economic performance of corporations. It provides a way to identify win–win situations where monetary and environmental performance can both be improved. But take-up by business is slow, which seems to go against the notion of strong competition driving economic performance. A recent standard, ISO 14051, has been produced by the International Organization for Standardization, and could bring substantial change to MFCA implementation and research. Drawing on Rogers (2003) theory of diffusion of innovation, and with a focus on the first two stages of the innovation-decision process, knowledge and persuasion, this study sought to analyze MFCA and predict how the 2011 release of ISO 14051 might be expected to influence take-up of MFCA by business, and what this might mean for future research. The analysis revealed that, when combined with ISO involvement, MFCA is well placed in terms of Rogers’ theory, with the future likely to see increased diffusion of MFCA and, as adoption rates increase, more opportunities for research in this area. Specific areas identified as a result of the analysis include: the introduction of new research methods, the need for theoretically informed research, and the potential to address new research questions previously considered impractical

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
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
