No full textEngineering applications on the eInfrastructure: The case of telecommunication measurement instrumentation
No full textRemote Instrumentation Services can provide unprecedented boost to the generalized use of sophisticated and costly scientific
equipment, and foster the diffusion of eScience applications. However, this paradigm does not only apply to large-scale laboratories and
devices, but it can be fruitfully employed even with smaller and relatively widespread measurement instrumentation adopted in engineering
applications. In this context, we consider the case of telecommunication measurements, and of their execution within the eInfrastructure,
by using a subset of the service capabilities. We highlight some specific aspects of this environment, and we present an application
example and some performance evaluation results
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

No full textAlthough access to remote laboratory equipment
through a networking infrastructure is becoming an actively investigated
and experimented topic, most current implementations are
dedicated to specific application environments. Nonetheless, essentially
the same basic structure, in terms of protocol and software
architecture, can be used to face a great deal of heterogeneous
experimental settings. The variability in the resources available to
users, both in terminal and access network capabilities, requires
a high degree of flexibility, abstraction, application independence,
and ease of configuration in the user’s access devices. A further
aspect regards the possible need of distributing the experiment’s
results to a large user population, which calls for the adoption of
multicasting. This paper reports the architecture developed and
the results achieved within the three-year term LABNET project,
which has addressed these issues within an integrated laboratory
environment, aimed at providing unified access to heterogeneous
equipment for a multiplicity of users with potentially different
capabilities and skills
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
