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

No full textKnowledge, attitudes, beliefs and practices of construction workers towards tetanus vaccine in Northern Italy
Get PDFConstruction workers (CWs) are both more exposed to tetanus and at higher risk to be inadequately immunized. Our aim was to evaluate tetanus immunization status and knowledge/attitudes towards tetanus vaccination in CWs in Italy. In this field report, the immunization status of 554 unskilled CWs (i.e. labourers). Immunization status was assessed recalling immunization booklets/certificates. Attitudes and knowledge were collected through a standardized questionnaire. In 240/554 CWs, immunization status was inadequate/not documented: in 184 subjects (33.2%), the last vaccination shot was older than 10 years, whereas basal immunization was incomplete in 20 cases, more frequently in foreign-born people (FBP) than in Italian born (IBP) (OR=7.116). In 198 cases (35.7%), an Occupational Physician (OPh) performed last booster, usually with monovalent (T, n=173) vaccine. The main reason for inadequate immunization was having forgotten the periodic booster (148/554; 26.7%), whereas 42 subjects (7.6%) deliberately avoided tetanus vaccine because of personal/religious beliefs, more frequently in FBP than in IBP (OR=3.182). In summary, the prevalence of inadequate immunization status was relatively high (43.4%): the high prevalence of \"forgotten boosters\" enlightens the key role of OPh in recalling and promoting vaccination policies. Moreover, the inappropriate use of Td vaccine points out the opportunity for educational campaigns in OPh
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
The management of air contamination control in operating theaters: the experience of the Parma University Hospital (IT)
No full textAs part of the overall management of a Hospital, the Hygiene Unit has specific tasks including the improvement in the levels of hospital safety by air quality monitoring in hospital environments to control the sources of infection and assessing the healthiness of hospital facilities. Operating theaters (OTs) and cleanrooms air quality control can represent a focal point considering that environmental contamination depends on not only factors such as characteristics and level of maintenance of Heating, Ventilation and Air Conditioning systems (HVAC), but it also depends on the number of people present, their behavioral habits, sanitation and disinfection procedures adopted. Several studies demonstrate a high variability in microbial air contamination in different OTs with similar HVAC, suggesting the need for achieving strict control over the factors affecting air quality. The control of air contamination, as an indicator of the quality care provided, therefore sets precise objectives, accuracy from a scientific point of view including planning, analysis and interpretation of results to propose corrective actions. However, there are no generally accepted standards for sampling nor threshold values on microbial air contamination. Aerobiology skills can improve the approach to involved issues. The monitoring plan of air quality assessment at the Parma University Hospital, by the Laboratory of Aerobiology, involves approximately 80 environments equipped with turbulent or mixed air flow. This paper describes the practical approach to air contamination control of the Hospital Hygiene Department at the Parma University Hospital as an example of how Health Departments can improve safety standards for patients and operators
