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
Detecting Replay Attacks by Freshness Annotations
No full textWe present a reduction semantics for the LYSA calculus extended
with session information and a static analysis for it. If a protocol
passes the analysis then it is free of replay attacks
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
A Formal Analysis of Complex Type Flaw Attacks on Security Protocols
No full textA simple type confusion attack occurs in a security protocol, when
a principal interprets data of one type as data of another. These
attacks can be successfully prevented by tagging types of each
field of a message. Complex type confusions occur instead when
tags can be confused with data and when fields or sub-segments of
fields may be confused with concatenations of fields of other
types. Capturing these kinds of confusions is not easy in a
process calculus setting, where it is generally assumed that
messages are correctly interpreted. In this paper, we model in the
process calculus LySa only the misinterpretation due to the
confusion of a concatenation of fields with a single field, by
extending the notation of one-to-one variable binding to
multi-to-one binding. We further present a formal way of detecting
these possible misinterpretations, based on a Control Flow
Analysis for this version of the calculus. The analysis
over-approximates all the possible behaviour of a protocol,
including those effected by these type confusions. As an example,
we considered the amended Needham-Schroeder symmetric protocol,
where we succeed in detecting the type confusion that lead to a
complex type flaw attacks it is subject to.
Therefore, the analysis can capture potential type confusions of this kind on
security protocols, besides other security properties such as
confidentiality, freshness and message authentication
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
Distinct myeloid population phenotypes dependent on TREM2 expression levels shape the pathology of traumatic versus demyelinating CNS disorders
No full text(Cell Reports 42, 112629; June 27, 2023) In the originally published version of this article, Han Gao, the first author of this paper, was given the position of corresponding author as well as lead contact due to a misunderstanding regarding these roles. After an explanation of the roles were given, the three original corresponding authors (Han Gao, Roberta Brambilla, and Limin Rong) agreed that corresponding author duties should be limited to Brambilla and Rong. Furthermore, the position of lead contact should be given to Limin Rong, who is designated as corresponding author and has accepted responsibility of handling communications about the paper from readers. The article has since been updated to reflect the accurate responsibilities of each author. The authors regret this error and any confusion that it may have caused
