No full textMethod and system for establishing an internet access by using a wireless local area network communication protocol from a mobile client station
No full textA method for establishing an Internet access by using a WLAN protocol from a mobile client station, via an access point to be chosen from a set of identified access points, includes: providing a general database of the identified access points with connection information; requesting Internet access using the protocol, successively moving through browsing through, selecting, associating, authenticating and configuring; establishing the Internet access of the mobile client station via the selected access point. Before and independently of the requesting the Internet access, connection information of at least a portion of the access points of the general database is downloaded into an onboard database of the mobile client station. The browsing through and selecting are carried out based on the downloaded connection information, without soliciting the general database and the identified access points

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
Multimedia Transport Protocol And Multicast Communication
No full textThe emerging of high speed networks provides the infrastructure for handling a wide set of new applications, covering distributed multimedia cooperative features. In this framework, multipeer communication is a major service/protocol issue because most of these applications exhibit the need for such a functionality. Besides many functions and mechanisms, the semantics of transport layer multicast conversation has to be defined. We show that a new service semantic called statistical-reliable, in which the reliability is enforced when desired by applications, is of major interest for the high-performance networking paradigm. This new reliability semantic can be implemented using a protocol akin to the XTP bucket algorithm. The interest of the developed protocol is that 1) it can perform efficiently on top of wide area (for instance ATM-based) networks as well as LANs, 2) it provides a continuous reliability service from best-effort to all-reliable as a function of the application require..
