Proprietà qualitative e quantitative, intensive ed estensive, e altre distinzioni (I)
Full text linkDiscussing a number of distinctions and definitions by Kant, Hegel, Helmholtz, Duhem, Cohen & Nagel, Bergman & Spence, Hempel, Carnap, Agazzi, and others, we propose a taxonomy of properties employed in different sciences. In the first part we discuss how properties (including relations and meta-properties) are conventionally singled out from basic characters through qualitative, comparative or quantitative concepts. We thus distinguish properties into qualitative and quantitative, and quantitative properties into distributed and undistributed, intensive and extensive. Mental properties do not differ from physical ones in being qualitative rather than quantitative, but qualitative or intensive rather than extensive. On the other hand, objective prediction functions are possible even for qualitative properties. In the second part we distinguish extensive properties into additive, additive up to the whole, and compoundable according to other functions. We thus find that quantities may be limited or unlimited, constitutive or accessory, transferable or non-transferable. Moreover, all properties may be either intrinsic or extrinsic, structural or behavioural, essential or accidental, and these distinctions should not be confused with one another. Finally, our characterization of the intensive-extensive distinction shows it is more neat and objective than granted by Hempel and Carna
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
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
[Morpho-functional evaluation of subjects who had undergone surgery for ano-rectal malformations using the Peña technique]
No full textThe approach to patients with Ano-Rectal Malformations (ARM) has undergone a substantial change in these last years due to the evolution of the studies of the anatomy and physiology carried out by Peña and de Vries. The authors report their experience on 15 patients and analyse the clinical and instrumental results according to the quality of life of the patients. There are different clinical criteria for the postoperative evaluation of these patients. The authors considered the Kelly, Kiesewetter, Peña and Holdschneider methods and compared the different values obtained. Moreover, they analysed the results of anorectal manometry performed in 10 patients and their correlations with clinical scores. The authors assert that the TC or NMR tests are unnecessary for these patients, since these methods demonstrate a correct position of the rectum within the muscular structure, but do not allow a correct evaluation of the quality of life of these patients. The clinical results obtained by the authors are satisfying; however, the number of patients is limited and the follow-up is relatively short
