Engineering 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

No full textA general framework for networked multimedia applications enabling access to laboratory equipment: The LABNET project experience
No full textThe issue of accessing remote complex laboratories in a networked environment and performing experiments and measurements in which several applications and diverse devices are involved is addressed. A proposal is described for a common architecture for enhanced multimedia remote device control. The aim is to have the ability to set up a "gate" device that is the structured sum of real devices (from routers to microscopes) and virtual ones (e.g. software applications). The architecture exploits the most recent WWW "products", using the flexibility of embedding Java within a middleware framework. The authors do not claim that this will be "the" common architecture in such environment, but this exercise is useful for highlighting a number of problems through the proposal of different sets of solutions. The definition and initial implementation of this concept is part of the activities carried on within the framework of the LABNET project, at the CNIT Multimedia Communications Laboratory in Naples, Italy. The project, which started in April 2000, aims at the implementation of tools for network access to real laboratories and the management of experiments at a distance. The main structure of the project and the on-going activities are also briefly described
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
