Ações de informação em ciência e tecnologia: aspectos institucionais em um modelo sociotécnico emergente
Full text linkInformation actions in science and technology: institutional aspects in an emergent sociotechnical model Considering initiatives from the Brazilian Institute for Information on Science and Technology (IBICT) regarding excellence of information on science and technology (S&T), this paper aims to identify theoretical aspects regarding information actions in mediating information institutes in S&T considering new forms of intervention and interaction of subjects with such institutions, starting from the hypothesis that they have a productive influence to rethink excellence criteria for information in S&T within dissimilarities in contexts of validation. The assumption here is the influence of a theoretical model named “sociotechnical emergent” in counterpoint, but in dialogue, with a previous model denominated “systemic”, bearing in sight current interventional and interactive forms reach using the Worldwide Web. The text is structured in three section approaching: i) the categorization of theoretical repertoire of S&T on information “user”, placing conceptual aspects better aligned to “systemic” or “emergent” models; ii) theoretical and epistemic theoretical constructions of the “information action” approach; and iii) bringing back theoretical-conceptual elements, building an interpretation oriented by the “information action in S&T” construct and taking IBICT action spaces and initiatives as an analysis object. Finally, there is a discussion on the relevance of the investigations performed in the ambit of the “emergent model” towards the questioning of paradigms around information, subject and management inherent to the “systemic model”, especially before the diversified forms of information validation in the current social and institutional scenery
Sujeito e agência informacional: comportamento, prática e ação.
No full textRegarding contemporary informational demands, we aim to relate informational agency approaches so as to bring light to conceptions of subject in information science. Aspects are identified transcending the intermediating context concerning the information system, stemming from the assumption that professionals, in a strict sense, are information users and actors, thus admitting other subjects with influence in informational policies acting in differing information regimes. So we consider informational challenges and contemporary theoreticians, researching informational agencies (behavior, practice and action) identifying converging and diverging aspects. We observe that the construct “information action” presents itself as an alternative comprehending new study objects – e.g. informational validation – as it considers, among other aspects, a broad notion of subject and coexistence of different forms of informational agency
Sujeito, Agência e informação: tradição e leituras transversais
Full text linkConcerning the emergence of new demands and informational settings regarding interactions and socio-technical links, we aimed to relate the constructs “information” and “agency” so as to obtain subsidies for a reflection on the perspectives of “subject” in the field of information. Hence, we considered aspects such as transversality of the production of knowledge; the historical trajectory of concepts; and the creation of objects, thus making it possible to identify what the study of informational agencies and subjects can allow the coexistence of traditional approaches, in the field of information science, and those involving transversal readings in dialogue with information philosophy and other knowledge within human and social sciences. In the case of the first approach – intertwined under the scope of disciplinarity – we introduced aspects involving objective, subjective and social dimensions of information, guided by the search and use of information. In the second one, information and agencies are thought beyond the limits of a single field, transversal through readings that can consider politics, ethics and economy, not restrained within the relations among subjects, institutionalities, technologies and informational resources, but also with everyday agencies found in multiple networks and regimes
Agentes, intermediações e instucionalidades: apontamentos sobre um mosaico interpretativo no campo informacional.
No full textIn our current informational set, we here consider the coexistence of specific technological objects with the dynamics of communicative network processes reflect and/or the influence of the agency of subjects and informative institutions. We infer that part of the difficulty in understanding this phenomenon comes from how fast these changes have been sticking out to researchers who, immerse in this new context, seek perspectives in which to report on their interpretations. We intend, in this book, to bring a few pieces of this interpretational mosaic found in the literature of Information Science in dialogue with Social Sciences and Philosophy, always seeking to understand the roles of subjects and institutions before shapeless and significant contemporary communicative contexts. We assume there is a possible way for this proposition to fit, passing through interpretations of new theoretical and conceptual paradigms concerning what goes in between subjects’ agencies and challenges for the intermediation of information in an institutional ambit
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
