A inserção e o impacto internacional da pesquisa brasileira em 'estudos métricos': uma análise na base Scopus

This research aims at analyzing the Brazilian scientific contribution on “metric studies” in the mainstream science through journals indexed in the Scopus basis, intending to visualize its insertion and international impact in the area. Mainly, to diachronically study the researches, the most productive authors and the scientific support network generated among them, as well as to identify the journals in which such production has been disseminated. It is based upon the three main target groups of current bibliometrics, as in Glänzel’s perspective (2003), and upon the impact of Brazilian researches in the international community through the citations received. Were found 263 articles and tables concerning the diachronical study and the highlighted researchers and journals were constructed analyzing the insertion in the target groups, the number of articles, number of citations and the average of citations. As results, researchers from the Federal Universities of Rio de Janeiro and São Paulo have stood out. All the researchers permeate the application of metric studies to several scientific areas, with emphasis on the health and biological sciences. The least contemplated researches were the ones whose objective was to develop and to discuss the bibliometrics as methodology, contributing to its on conceptual-theoreticalmethodological development, as well as those focusing on contributing, assessing and guiding scientific policies. We conclude by suggesting scientific and academic policies which motivate the researchers to publish in journals indexed in international bases in order to internationalize Brazilian science.

Estudos de Análise de Cocitação de Autores: uma abordagem teórico-metodológica para a compreensão de um domínio

This piece of research aims at analyzing the absolute and relative co-citation indicators, especially Salton’s Cosine and comparing the contribution of these indicators to the understanding of a domain, applying them to the universe of "Metric Studies" at the BRAPCI base. It also aims at presenting the co-citation network generated from the absolute frequencies and highlighting the groupings of co-cited authors, depending on the relative values, integrating and explaining the information from the two indexes. The domain analysis, by means of its 11 approaches, including “Bibliometric Studies”, focuses on the science characterization and evaluation, in that it allows us to identify and to analyze the conditions under which the scientific knowledge is constructed and socialized. In these studies, the contribution of citation and co-citation analysis is highlighted. Of the total of 147 articles retrieved at BRAPCI base, the authors cited in at least 11 articles, in a total of 38 researchers, were selected. The 38 x 38 symmetric matrix with the absolute frequencies of co-citation and the matrix with the relative values of Salton’s Cosine were generated. The co-citation network with absolute frequency values were constructed, through Ucinet software. Cluster analysis of data with relative values wer performed, using the SPSS software. Significant differences between the absolute and relative indexes, with some high absolute values of co-citation were observed; when considered in relation to the presence of each author, their significance is decreased. As to the generated network, seven groups were determined, in which only one is established for close themes and comes from co-citations in the original sense of the term. Five groups present closeness in absolute and relative indicators. It can be concluded about the importance of the studies of authors' co-citation analysis, which associate the two indexes, absolute and relative, in order to visualize and understand the underlying structures of a scientific domain.

Investigação da produção científica no tema 'Estudos Métricos' na base de dados Brapci: uma análise bibliométrica

The objective of this research is to analyze the scientific production about „Metric Studies‟. It was used the data base BRAPCI (data base of articles and journals in Information Science) to outline the authors and institutions that produced more. As research procedure it was analyzed the articles with the keywords that represent the area of metric studies such as: Bibliometric, Cientometric, Informetric, Webmetric and Patentometric between 1991 and 2011. It was analyzed the variable in study, building the collaborative network through the software Pajek. From these results, it was possible to delineate the tendencies presented in the scientific community on this subject from the data base BRAPCI.

A pesquisa sobre o fazer pesquisa: uma análise de citação da literatura periódica em Ciência da Informação

Introduction: This paper considers that information science (IS) literature covers a diversity of thematics with low emphasis on researches about conducting research. The study analyzes the scientific production of authors who investigate about research methodology in the information science (IS) literature, and the references used to lay the foundation of the methodological issues regarding the area. It discusses the methodological and epistemological positions of the leading researchers highlighted as the most productive investigators on the subject in the country. Method: The research adopts the content analysis coupled with metric studies to contextualize the indicators related to productivity, to the types of authorship and citation analysis. The bibliographic coupling method is considered an analysis mode which analyzes concomitant citations. It develops a theoretical framework about the importance of scientific production analysis in different knowledge fields. The study investigates, from a theoretical perspective, the concepts about research methodology and the complementarity between methodology and epistemology in conducting research. Results: The results of the analysis showed that the production of the highlighted authors presents the methodology as a thematic focus to be applied to IS contexts, as well as a research object in the field. The prominent productivity of the authors is justified especially by deepening the meta studies about the ways to conduct research in IS. This study also identifies a trend to single-authored studies about the theme. Conclusions: The research considers that meta studies and applied and methodological studies are important to recognize a consistent theoretical and practical core in the IS area. Regarding the epistemological influences identified by the citation analysis, the study observes that the critical rationalist epistemology and the social and political epistemology are highlighted in the construction of the theoretical framework of the most productive authors.

Estudo sobre as unidades de medidas das grandezas físicas básicas: comprimento, massa e tempo

Measurement units are used almost automatically nowadays, but few people know the origin of the units of length (meter), mass (kilogram) and time (second). And do not care to know what were anciently units of which our ancestors used, the difficulties that existed to make a set of measures. The aim of this work is to make a historical approach, through various units of measure. They are old, unusual to others that have been forgotten since the standardization of meters, and is also discussed about the metric system Englih (Once and foot), AV system (eg pound grain) that are still used in some countries like United States and England, the Troy system consisting of units of measure for precious stones and metals (eg gold and diamond) are also cited some physical concepts as reference: inertial, non-inertial; mass: gravity, relativistic, inertial

Patentes patéticas

The objective of this project is to publish a book of scientific dissemination aimed at the subject of intellectual or industrial property, in particular patent, and its approval process. Based on a series of weekly blog posts published by its author, Patentes Patéticas use scientific, literary journalism and humour techniques to analyze a selection of U.S. patents that stand out for their questionable utility and criticize the number of patents granted as a metric of technological innovation in a country

Sílabas métricas em Terenciano Mauro, De Syllabis, 997-1299

This monograph addresses to the study of Latin metrical notions and concepts as showed in the volume VI of Heinrich Keil’s work, entitled Grammatici Latini (GL): Scriptores Artis Metricae. From that book, it was chosen Terentianus Maurus’s work for corpus, particularly the excerpt between verses 997 and 1299 of De Syllabis, a part of Terentianus’s De Litteris, De Syllabis, De Metris, which is a metric manual written in verses. Until now, there are only three translations of that text into modern languages: two in Italian (one of them was used for comparison with the translation prepared for this monograph) and a French one. That work still contains many reference notes whenever Terentianus Maurus uses ancient authors to demonstrate his explanations on Metrics. Thus this research intends to join in other analysis made on Latin metrical manuals that have already been translated or are still going to be, as well as to notice the importance and the specific value of meter in ancient poetry

Velocidades superluminais na relatividade geral: métrica de Alcubierre

The constancy of the speed of light appears to be an unbreakable barrier for future interstellar journeys, tending to infinite energy would be needed to achieve such speed. However in the general relativity one can circumvent this limit and get arbitrarily higher global speeds, without violating the constancy of the speed of light. The so-called “warp-drive metrics is a theoretical means to achieve global superluminal speeds. The Alcubierre metric is one case in which the science fiction inspired reality, from which was drawn the term “warp-drive. In the present work, a study of the theories of special and general relativity and of some works on solutions that allow superluminal speeds will be done

A segmentação não-convencional de palavras em textos do ciclo II do ensino fundamental

This paper deals with unconventional segmentations of words in texts produced by students of the last four years of elementary school. The main hypothesis is that these data allow us to observe the characteristics of written and spoken utterances. Through analysis of data on prosodic constituents, we argue that students deal with (conflicting) hypotheses on the organization of unstressed syllables into prosodic constituents: metric feet, prosodic word and clitic group. We found evidence that unconventional spellings have their main motivation in the difficulty of students to assign the status of written word to grammatical items that are prosodic clitics.

Aplicações do fluxo de Ricci à teoria da relatividade geral: estudo dos buracos negros

The flow of Ricci is an analytical tool, and a similar equation for heat geometry, a diffusive process which acts on a variety of metrics Riemannian and thus can be used in mathematics to understand the topology of varieties and also in the study geometric theories. Thus, the Ricci curvature plays an important role in the General Theory of Relativity, characterized as a geometric theory, which is the dominant term in the Einstein field equations. The present work has as main objectives to develop and apply Ricci flow techniques to general relativity, in this case, a three-dimensional asymptotically flat Riemannian metric as a set of initial data for Einstein equations and establish relations and comparisons between them.

A simple observation concerning contraction mappings

In this short note we show that the results obtained by Walter in [4] remain valid if we change the metric by another metric. Furthermore, if we use the norm jjT; given in [3], Theorem B in[4] remains valid.
