La morte cardiaca improvvisa in Italia: dimensioni, percezioni, politiche ed impatto economico-finanziario
No full textThis study is based on the consideration that sudden cardiac death (SCD) incidence is increasing in
today’s society and, despite the efforts of clinicians, there is great lack of awareness and focus for its
prevention on behalf of society and institutions.
During 2006 a research project on SCD was initiated in Italy by the CUSAS (Centro Universitario
di Studi in Amministrazione Sanitaria) and the Institute for Internal Medicine and Cardiology of the
University of Florence with the intention to: estimate the dimension(s) of the SCD phenomenon in the
general population; underline the economical consequences of SCD; identify the causes for the lack
of interest in SCD; evaluate the degree of use of biomedical technologies for SCD prevention, and
compare the actual scenario with the ideal one (driven by treatment guidelines implementation); the
last part of the study analyzes economical sustainability of the implementation of the 2006 European
Society of Cardiology new guidelines.
We estimated an occurrence of SCD in young subjects (between 35 and 65 years of age) of roughly 9300 cases per year (~17% of total): nearly one case of SCD in 5 afflicts young and still active individuals. Causes of the phenomenon vary greatly: in older subjects the pathology that most frequently
causes SCD is ischemic heart disease, whereas in younger subjects it is more often related to heart failure. The most optimistic hypothesis is that each year SCD causes the loss of nearly 600 000 life years.
We came up with a first estimate of the socio-economic impact due to life years lost each year to
SCD, using net individual work salary for the basis of the calculation. Results are extremely variable
(between 6.482 and 12.216 millions of euros each year).
Considering that half of the events occur in patients in whom SCD can be accurately predicted,
due to their high risk factor, it is possible to estimate the financial investment necessary to prevent
SCD in at least these individuals. The DRG tariff is used as a proxy for the economic calculation of
the procedure costs. An additional investment of 310 million euros would have been necessary, which
represents only 0.33% of the national health budget for that same year.
We strongly believe that preventing SCD is not only financially feasible but very beneficial from
the societal perspective.

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
