La prospettiva di genere nella valutazione dell’esposizione ai rischi lavorativi
No full textIn order to create a correct gender-sensitive risk assessment, hazards identification and exposure evaluation have to be led considering several inequalities related to gender differences. In this respect, authors put their attention to different occupational segregations (both horizontal and vertical) and to various hazards (injuries, chemical, physical, ergonomic, biological and psychosocial) to which female and male workers are submitted, to create a more realistic picture of all the risks which mostly affect safety and health at work. To generate a complete view of occupational risks, authors also consider the unequal domestic load distribution between male and female workers which takes the latters to be exposed to multiple hazards, both in domestic and working places. It also provides an overall picture of useful indications to a correct evaluation and to a proper risks management, to improve health and safety level of all worker
Possible Internalization of an Enterovirus in Hydroponically Grown Lettuce
Full text linkSeveral studies have shown that enteric viruses can be transferred onto the surface of vegetables and fruits through spray irrigation, but, recently, reports have suggested viral contamination of vegetables sub-irrigated with reused wastewater. Hydroponic cultures, used to grow ready to eat fresh lettuce, have also been used to study the possibility of viral absorption through roots. This study was conducted to assess a possible risk of viral contamination in lettuce from contaminated water. The leaves of lettuce plants grown in hydroponic cultures where the roots were exposed to water containing Coxsakievirus B2, were analysed for evidence of the virus. The plants and water were sampled at different times and virus was measured using quantitative RT-PCR and infectivity assay. In leaf samples, the lowest observed infective data were lower than the qRT-PCR detection limits, suggesting that free viral RNA or damaged viruses are eliminated rapidly while infectious particles remain stable for a longer time. The obtained data revealed that the leaves were contaminated at a water concentration of 4.11 ± 1 Log Most Probable Number/L (8.03 ± 1 Log GC/L) a concentration observed in contaminated untreated water of wastewater treatment plants. However, the absorption dynamics and whether the virus is inactive in the leaves still remains to be clarified. Nevertheless, this work has practical implications for risk management in using reclaimed water for agricultural use; when irrigated vegetables are destined for raw consumption, virological contamination in water sources should be evaluated
Sperimentazione di un nuovo modello di valutazione della sensibilità al genere nell'analisi dei rischi lavorativi
No full textNonostante la normativa vigente in materia di salute e sicurezza sui luoghi di lavoro abbia introdotto l'obbligo di considerare il paradigma di genere nel processo di analisi dei rischi lavorativi, ancora oggi, possiamo rilevare un'evidente difficoltà di tradurre questa importante affermazione in prassi e procedure operative. In questa cornice si inserisce il progetto di ricerca multidisciplinare dell'Università di Pisa, con la collaborazione dell'INAIL Regionale, che ha come scopo quello di individuare e progettare un modello di valutazione riguardante l'applicazione dell'approccio di genere all'analisi dei rischi lavorativi. Nella fase iniziale del progetto di ricerca è stata condotta un'attenta revisione della letteratura al fine di individuare gli ambiti di indagine influenzati dal paradigma di genere nei luoghi di lavoro. Sono stati individuati così quattro settori di studio inerenti la struttura e l'organizzazione aziendale, la salute e la sicurezza sul lavoro, l'informazione, la formazione e la partecipazione dei lavoratori/trici e gli aspetti collegati alla conciliazione lavoro-famiglia. Per ciascun ambito di studio sono stati elaborati elementi di indagine (items) organizzati in uno strumento di valutazione per le aziende (questionario). Tale strumento di valutazione verrà validato per la comprensibilità e l'accettabilità mediante somministrazione assistita ad un numero ristretto di aziende, al fine anche di verificarne la reale applicabilità sul campo e la reperibilità delle informazioni richieste. Una volta terminata la fase di validazione, la somministrazione sarà estesa ad un numero maggiore di aziende, individuate e selezionate per diversa tipologia di comparto produttivo e per differente numero di addetti/e, allo scopo di verificare l'efficacia e l'agevolezza dello strumento stesso all'interno del sistema di valutazione dei rischi di ogni azienda. Durante questa fase verranno, inoltre, assegnati ad ogni item dei punteggi che attribuiranno ad ogni azienda testata un risultato finale che si tradurrà nel loro grado di adeguatezza (modello interpretativo 'a semaforo') di inclusione del 'parametro di genere' nel processo di valutazione dei rischi. Lo strumento, infatti, una volta completata la messa a punto, potrà consentire ad ogni azienda di auto-valutare l'adeguatezza e l'efficacia del proprio percorso di gestione del rischio in ottica di genere e di individuare le possibili azioni di miglioramento, anche attraverso il portale INAIL
Salute, sicurezza sul lavoro e differenze di genere: necessità di una adeguata valutazione dei rischi [Occupational health and safety and gender differences: Need for the identification of an adequate risk assessment ]
No full textRecent legislation has made mandatory to perform the risk assessment taking into account gender differences. This should imply to consider not only the simple differences due to biologic difference between male and female workers, but also what is more related to the social role they really play in the current society. This second aspect of gender difference has not yet been addressed from a technical point of view. The University of Pisa in cooperation with INAIL has recently started a project aimed at identifying technical tools to perform a risk assessment which took into account gender difference
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
