Aiming for an Online/ Onsite Format and Finally Moving to Online Only
Full text linkBased on the past two years of experience as an online event due to the Covid-19 outbreak, DATE 2022 has been planned to cope with the uncertainty of the situation, having two days onsite, in Antwerp, Belgium, from March 14 to 15, 2022, to be followed by an online program until March 23, 2022. A different organization and format had been adopted to engage the DATE community, with a two-day rich program and numerous talks and panels to gather again, in person. The scientific program online had been completed by live panels and presentations to offer a valuable virtual experience. Unfortunately, for the third year in a row, DATE moved to a completely virtual event, which nevertheless attracted a broad audience.status: Published onlin

The (in)security of proprietary cryptography
Full text linkContains fulltext :
140089.pdf (Publisher’s version ) (Open Access)Proprietary cryptography is a term used to describe custom encryption
techniques that are kept secret by its designers to add additional security. It is questionable if such an approach increases the cryptographic strength of the underlying mathematical algorithms. The security of proprietary encryption techniques relies entirely on the competence of the semi - conductor companies, which keep the technical description strictly confidential after designing. It
is difficult to give a public and independent security assessment of the
cryptography, without having access to the detailed information of the design.
The first part of this dissertation is dedicated to an introduction of the
general field of computer security and cryptography. It includes an extensive description of the theoretical background that refers to related literature and gives a summary of well - known cryptographic at
tack techniques. Additionally, a broad summary of related scientific research on proprietary cryptography is given. Finally, the technical part of this doctoral dissertation presents serious weaknesses in widely deployed proprietary cryptosystems, which are still actively used by billions of consumers in their daily lives.Radboud Universiteit Nijmegen, 21 april 2015Promotores : Jacobs, Bart, Verbauwhede, I.

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
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
