Ongoing tetanus prophylaxis of injured patients in five hospital emergency rooms
No full textThe adequacy of antitetanus prophylaxis given in five hospital emergency rooms to 729 individuals up to 15 years, suffering from different types of injuries, was evaluated retrospectively using vaccinal data retrieved from a terminal of the computerized files of the City of Milan Health Authority operated in our Department. Comparing the recommended treatment (according to the guidelines issued by the Italian Ministry of Health, 1982) with that actually obtained, we have classified the subjects into three ("correctly treated", "undertreated" and "overtreated") groups. Correct treatment ranged from 70 to 90 percent, undertreatment from 4 to 6 percent, and overtreatment from 8 to 26 percent at the different hospitals. Undertreatment was most likely in incompletely immunized patients (having previously received one or two doses of tetanus toxoid), while overtreatment was much more common in patients fully immunized. By comparison, 545 patients sixteen and older, whose immunization history was unknown, were evaluated to obtain information about the behaviour adopted by the physicians in the same circumstances. Grouping the subjects by age we found that in two hospitals the highest proportion of untreated (18 and 25 percent) belonged to the group of individuals more prone to the disease (over 60 years of age). Compliance with the Ministerial Instructions would have led to an increase in the use of tetanus toxoid and to a decrease in the use of human immunoglobulin, improving the quality of prevention without adding to its cost

Epidemiology of tetanus
No full textThe vaccinal preventive measures which were made compulsory since 1963 for the new working levies of some professional high risk categories, and since 1968 for the newborns, contributed to a large extent to the tetanus control in our country. In the last twenty years a progressive drop in the notified tetanus cases was observed. The epidemiology of this disease is conditioned, on the one hand by the correct application of the legal directions in force; on the other hand, by the level of health education, acquired by those who have not yet been involved, so far, by the compulsory antitetanus vaccination
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
