Quello sulla valutazione d'impatto sociale è un decreto rivoluzionario, che per l'economista Maria Vella con i suoi principi riconduce al sistema dei valori connaturato al Terzo Settor
Analisi citazionale e indicatori bibliometrici nel modello Open Access
Get PDFThis article is focused on the bibliometric methods used for research evaluation, within the well known field of the bibliometrics which uses mathematical and statistical techniques to analyze the publications distribution patterns, and to explore their impact into the scholarly communities. While the bibliometric methods are used more often in the LIS, bibliometrics offers a wide range of applications in a variety of fields of knowledge. Since the research evaluation requires a double approach: quantitative (bibliometric analysis) and qualitative (peer-review, panel...), the fundamental idea is that the measurement of the scientific knowledge uses both the methods.
Though the IF or impact factor is the most well known bibliometric index, is not the only one suggested by ISI (now Thompson) to refer. In the Open Access world are spreading a wide number of initiatives and projects regarding the “bibliometrics” field, in which are being testing alternative solutions to the traditional IF, for example the Eigenfactor, the Hirsch index and its variations like the g-index, a-index, h-b-index, tools that mark a meaningful change in this fascinating field.
While the indicators “author-produced” are the citations, those “reader-produced” are usage data collected through webserver and linkresolver logs. A quantitative bibliometric indicator of new generation is the Usage Factor UF, complementary but non substitutive of traditional or alternative impact factor indicator. It will be necessary to organize the log data collection to share methods to obtain significant analysis. The article goes over some examples of new tools/projects for citational analysis in the Web area, among these the Web Impact Factor (WIF), and for the statistical analysis of logs and data, both bringing back to the new science known as metric of the web or Webometric.
Within the OAI framework there are many research projects of the webometric type, involving the intellectual output archivied into the repositories and their impact within the constitutive processes of the scholarly communication.
The theory assuming that an open access article in more likely to be read and therefore cited is matter of international debates and object of several studies, aimed to analyze the effects of the open access model and of the download on the citational impact. The article closes with a critical report on some of the most important works investigating the validity of this theory, from the original study of Lawrence, on Nature 2001, to the most recent works, the three postulates of Kurtz, the analysis run in 2006 by the Cornell’s Library staff on the MathSciNet database, the study of Moed which imposed a completely new methodological level with the introduction of the “variable citation window”.
Useful tools for the citational bibliometric analysis, on the statistical usage measurement of the researchs for the successful data monitoring, should be in the hands of the research producers, not in the hands of those commercial oligopoles that can influence the investment strategies and the national and international policies for the research
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
