Health surveillance for former asbestos exposed worker: A specific programme developed in an Italian region
Full text linkAsbestos-related diseases usually have a long latency since first exposure and this legitimates a health surveillance programme addressed to asbestos workers after the cessation of their occupational exposure. After a brief history of health surveillance initiatives performed in Italy as well as in other countries, we describe a regional programme for former asbestos-exposed workers, focusing on organizational features. A regional group of experts defined its operational and economical aspects. The Regional Council supported the whole programme, making it free of charge for all subjects who fulfil the predefined enrolment criteria (being resident in the region, being younger than 80 years old with cessation of occupational asbestos exposure within the last 30 years). The programme activities are classified in two levels: a first level for a basic health evaluation and a second level for in-depth analyses. In order to guarantee an homogeneous delivery in the whole region, the programme has to be performed by public health services with a quality control of activities. The involvement of specific public health services and the cooperation of social stakeholders are expected to play a major role in overcoming still open critical issues, such as the lack of programme existence awareness and adhesion, the correct stratification of subjects for the follow-up, and the real homogeneous delivery of the health surveillance in whole region
Scomposizione del guadagno di speranza di vita per morti evitate in Toscana
No full textLa speranza di vita (SdV) è tra i più importanti indicatori di civiltà di una zona/popolazione. Essa è infatti il portato di fattori economici, ambientali, sociali, oltreché sanitari. La Toscana è tra le cinque regioni italiane più longeve: nel 2015 la SdV alla nascita (SdVn) era 80,6 anni per maschi e 85,1 per le femmine. La scomposizione del guadagno o della perdita di SdVn per tipologie delle morti (evitate ed aumentate) fornisce indicazioni sulle azioni che l’hanno determinati
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
Breast cancer in healthcare shift-and night-workers – preliminary results of a case control study and risk management
No full textShift work, in particular the night shift, has a significant impact on health, especially increasing the onset of digestive, cardiovascular and oncological pathologies. In 2019, IARC confirmed the shift and night work as a probable carcinogen for humans (Group 2A), due to its association with breast cancer. Mechanisms involved are genetic predisposition, de-synchronization of circadian rhythms due to sleep losses with alterations in the cell cycle’ regulation and immunological deficiencies. Nevertheless, epidemiological evidences are still limited. The purpose of this case-control study was to estimate breast cancer risk due to night shift work in health settings also considering some possible confounders such as personal and organizational factors. Data were collected by a dedicated questionnaire investigating shift work exposure, along with other personal risk factors for breast cancer. Overall 433 subjects (79 cases and 354 controls) were recruited from two large health settings in central Italy. The preliminary results showed an increased risk of developing breast cancer in female workers who have used oral contraceptives for a period from 5 to 20 years, compared to the subpopulation that does not use it (OR 2.70, IC 95% 1.21 – 6.01). No significant association was found with shift work exposure. The prolonged use of oral contraceptives as birth control method could have relevant health and organizational implications in health care settings. Further efforts are warranted to clarify the role shift work and contraceptive use on the development of breast cancer
