Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
Parazitarnye antropozoonozy kak vyrazhenie edinstva zhivotnogo mira s chelovekom
The author discusses Kozar's point of view as to the question of definition of the notion „anthropozoonosis" and the epidemiological division of parasitic anthropozoonoses into main groups, as suggested by Kozar. Assuming that the epidemiological criteria of the classification of parasitic diseases should be in accordance with general biological principles obligatory in this regard, the author suggests that the only right definition of the anthropozoonosis parasite should be first of all based on a fundamental etiological (and at the same time epidemiological) element of the invasive diseases, i. e. on the animal as the source of infection for man. In the subsequent part of this work the author, basing on Kozar's interpretation of the phenomenon of specificity of the parasites, and the criterion, admitted by himself, to consider the invasive disease as anthropozoonosis (animal organism as source of parasitic invasion for man), is of the opinion that invasions of such parasites as T. solium or T. saginatus (very specific for man) should be consequently considered as strict (incontestable) anthropozoonoses, others however, in the course of which the specificity is less distinct - as relative anthropozoonoses. Such a division, being in accordance with the biological premises mentioned above, has also a practical importance in the analysis of epidemiological processes as well as in the practical work on finding new methods for eradication of invasive anthropozoonoses. When discussing the localization of parasites in the organisms of hosts and further, the problem of vectors and intermediate hosts, the author emphasizes the significance of the focus problem of many parasitic anthropozoonoses for better comprehension of the evolutional interdependence between the organisms of parasite and host, which doubtless are one of the expressions of unity of the animal world with man
Appropriate Similarity Measures for Author Cocitation Analysis
We 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
Patogenez invazionnykh boleznejj na fone teorii stressa
The author stating that the defensive reactions of the body of the host to the invasion of parasites has a stressor character he deals closer with the invasion of the larvae Ascaris suum Goeze, 1782 as a stressor which causes a typical alarm reaction (AR), which in turn is an element of the general and local adaptation syndrome (GAS and LAS). In particular he submits to discussion the current views on the changes in the haemogram of hosts of the larvae of worms and the observed differences of these changes in relation to changes taking place in the blood owing to the action of other, not parasitic stressors, explains among others by the allergic character of the pathological changes of the host's organism in parasitological invasions. The author stresses also the meaning of the vitamin C defficiency for the development of the pathological processes in invasive diseases and sees the possibility to regard the parasitologic stress as the control mechanism by way of increasing the production of the hormones of the pituitary gland and adrenals and by way of influencing the course of the allergic proccsses in organisms affected with a parasitic invasion. Expressing the opinion, that Selye 's theory is particular useful for the synthetic presentation of the problem of the pathogenesis of parasitic diseases the author points, however, to the need to develop studies on the role of the central nervous system, which according to his view is very essential in the pathogenesis of invasive diseases
Vitaminy i parazitnye izvazii
In commemoration of the 50th anniversary of the vitamin B discovery by Kazimkrz Funk, the author describes in a series of examples chosen for that purpose, the value of varius vitamins in the course of parasites invasions, emphasitzing the role of those parasites as factors handicapping vitamin exchange in the body of the host
Dispelling the Myths Behind First-author Citation Counts
We 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
We 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
