Mathematics subject classification and related schemes in the OAI framework
Full text linkThis paper aims to give a feeling of the roles that discipline-oriented subject classifications can play in the Open Archive movement for the free dissemination of information in research activities. Mathematics, and Mathematics Subject Classification, will be the focuses around which we will move to discover a variety of presentation modes, protocols and tools for human and machine interoperability. The Open Archives Initiative (OAI) is intended to be the effective framework for such a play. In the first part of this paper, we start by describing the most important subject classification schemes in mathematics and related disciplines. Then we sketch the structure of discipline-oriented schemes in view of browsing and we give an account of different browsing modalities, implemented in the tools we produced and collected in The Scientific Classifications Page. Finally we give an insight on the design, implementation and use of a programming language for the generation of hypertextual presentations of complex structured data. In the second part, we list different strategies for e-print communication in scientific research, up to the basic definitions of the Open Archives Initiative. A review of the functionalities actually implemented in OAI compatible archives managed by the EPrints software will lead us to some working hypotheses about the roles that subject classifications in mathematics and related disciplines can play in the scenarios of the Open Archives movement

CHANGES IN SLEEP WAKING CYCLE INDUCED BY LESIONS OF MEDIALIS DORSALIS THALAMIC NUCLEI IN THE CAT
No full textBilateral lesions of medialis dorsalis (MD) thalamic nuclei in chronically implanted cats disrupt the sleep-waking cycle by inducing a reduction of both slow-wave and desynchronized sleep and a corresponding increase of wakefulness. Bilateral lesions of the anterior thalamic group produce some postural deficits but no changes in the percentage of sleep and wakefulness. The hypothesis that MD lesions alter the sleep processes by interrupting an anterior forebrain-MD-cortical link has been put forward
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
