A preliminary analysis of volcanic Na-Tech risks in the Vesuvius area
No full textThe area surrounding Vesuvius is considered as one of the most hazardous zone in the world. Several civil protection actions (prediction and prevention, emergency plans, evacuation plan) have been managed for the population but, quite surprisingly, industrial risks triggered by the interaction with this catastrophic natural event have been neglected (Na-Tech risks). Furthermore, Naples and its province have several industrial areas, two industrial harbors with LPG and fuel docks, and large fiiel storage plants, in the close surrounding of crowded suburbs. The analysis of volcanic Na-Tech risks presented in the paper shows a revised event tree starting from simplification of geophysicist studies, taking into account only the possible interaction with industrial equipment. Among the eruption phenomena (tephra fall, lava flows, pyroclastic flows and surges, atmospheric phenomena, pyroclastic bombs) the tephra fall has been analyzed in the following, starting from the intensity of explosive eruption predicted by Italian Civil Protection. ©2009 Taylor & Francis Group
The Risk Related to the Interaction Between Natural Hazards and Technologies
No full textA large European integrating project on early recognition, monitoring and integrated management of risks related to emerging and new technologies (iNTeg-Risk) has recently started. Among several research activities, a specific task has been devoted to the interaction of natural hazards and technology (Na-Tech risks). The main goal of this task is to improve the resilience of industrial facilities to technological accidents caused or aggravated by natural hazards. In this context, the authors have analysed Na-Tech accidents due to impact of earthquakes, floods and lightning on chemical and process plants, aiming at giving a general framework for the assessment of industrial risks
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
The risk of storage plant of pyrotechnics
No full textRecent updating of Seveso Directive have made mandatory safety report of storage plants of pyrotechnics (fireworks). However, few guidelines are published in the open literature. The following work deals with the determination of maximum explosion pressures in confined and vented enclosures containing hazardous substances ranging from high-energy explosives to low-energy pyrotechnics.

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
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
