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
The occupational and active research, diagnosis and reporting of occupational diseases (Il medico competente e la ricerca attiva, diagnosi e denuncia delle malattie professionali)
No full textThe Occupational Doctor plays a key role on the protection of workers safety and prevention of occupational and work-related disease. His training and his need of updating, due to the constant transformation of work, the evolution of technology and the medical progress, set him in the center of all activities carried out to protect health in workplaces. The Occupational Doctor should devote special attention to the working anamnesis as well as to the pathological anamnesis both close and remote. He should also pay attention to semeiotics. Another important element is the relationship between the Occupational Doctor and the Doctor of General Medicine (MMG); this synergy is of vital importance in protecting health and in investigating diseases whether occupational or not. D.Lgs. 81/08 emphasizes this synergy, in fact name and phone number of Doctor of General Medicine is compulsory in Case History. Major source of information for aliform of prevention is the survey of occupational disease which is a tool for epidemiological control. The use of a systematic collection of data, of protocols, of guidelines and of scientific evidence is the basis for identifying occupational diseases, their diagnosis and subsequent denunciations. This is the line suggested in MAL PROF informative system, made for registration of work-related diseases, and which is important, with other instruments, in realizing an integrated informative system for prevention in workplace. The Covenant for the Protection of Health and Prevention in Workplaces (DPCM 1711212007) indicates the strategic objectives of the National Health System for the consolidation and development of the existing system and of the programs promoting health and safety. These include the growth of the culture of prevention and of the epidemiological control of occupational diseases. The Occupational Doctor has an important role because he can identify the early onset of diseases during the working age and start all forms of prevention and health promotion. In the case of diagnosis of a suspected professional disease the Occupational Doctor has three distinct obligations. The first is to report to the legal authority (C.P.P. art. 365). The second requirement is the declaration of the occupational disease (D.P.R. 1124/65 art. 139) and the third is to issue the first certificate of occupational disease for compensation insurance (D.P.R. 1124/65 artt. 53, 251). © PI-ME, Pavia 2008
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

No full textAppropriate 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
