Attività del gruppo vaccini della SItI e calendario vaccinale per la vita
No full textAs a consequence of the revised title 5th of the Italian Constitution, the regional devolution on health organization
has led to a significant five-year drift in the vaccination offer following the absence of a National
Immunization Plan. Thus, the Società Italiana di Igiene Medicina Preventiva e Sanità Pubblica (SItI) identified
the need to provide disoriented public health operators a scientific support for a larger immunization offer
based on the equity principles. Consequently, the SItI Vaccine Working Group issued numerous evidence-based
recommendations on the immunization policies and practices (for instance, the Childhood Immunization
Schedule, the Adulthood Immunization Schedule, and so on), based on the interactive discussions with other
national scientific societies and all the stakeholders in the field. Eventually, it is worthwhile to mention the
last outcome of this fruitful cooperation: the Immunization Schedule for Life, issued in March 2012. It emphasizes
the early start of adequate vaccination practices in the childhood, followed by the integration of
other relevant immunization practices in the adolescence and adulthood until the elderly. This holistic and
integrated approach could allow to reach the quality objectives, underlined in the new 2012-2014 National
Prevention Plan, and to satisfy the equity principle of a homogeneous vaccination offer countrywide
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
Booster vaccination: The role of reduced antigen content vaccines as a preschool booster
No full textThe need for boosters for tetanus, diphtheria, pertussis, and polio, starting from preschool age, is related to the waning immune
protection conferred by vaccination, the elimination/reduction of natural boosters due to large-scale immunization programs,
and the possibility of reintroduction of wild agents from endemic areas. Taking into account the relevance of safety/tolerability
in the compliance with vaccination among the population, it have been assessed whether today enough scientific evidences are
available to support the use of dTap-IPV booster in preschool age.The review of the literature was conducted using the PubMed
search engine. A total of 41 works has been selected; besides, the documentation produced by the World Health Organization,
the European Centre for Disease Control, and the Italian Ministry of Health has been consulted. Many recent papers confirm
the opportunity to use a low antigenic dose vaccine starting from 4 to 6 years of age. There is also evidence that 10 years after
immunization the rate of seroprotected subjects against diphtheria does not differ significantly between those vaccinated with
paediatric dose (DTaP) or reduced dose (dTaP or dTap) product.The dTpa vaccine is highly immunogenic for diphtheria toxoids
regardless of prior vaccination history (2 + 1 and 3 + 1 schedules)
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
