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
Impiego di dati MODIS in supporto alla valutazione del rischio associato a microrganismi patogeni in ambiente acquatico
No full textWe show the first results of a study aimed to set simplified procedures and methodologies to use MODIS data and derived products for activities of sea water control and monitoring. The research is carried out in the framework of a project supported by the Ministry for Health, concerning the development of criteria to evaluate the environmental and sanitary risk due to pathogenic micro-organisms in water environment. The remote sensing team acts in support of the biologic research teams that study the environmental conditions that favour the development and growth of such micro-organisms. MODIS data are selected, downloaded, organized in an easy-to-read format and analyzed by integrating with measurements performed by the other teams, in a georeferenced data-base. The goal of this study is to make the great information content of MODIS data available for operational use, providing public organizations in charge of environmental risk management with an operative tool, easy to use and at low cost, to support conventional techniques
Occupational safety and major accident hazard at an industrial park,
No full textLarge chemical parks feature a number of single establishments, managed by different companies, which share materials and structures in a restricted area. The duties of Occupational Safety and Health (OSH) man-agement are spread among a number of employers. A number of major accident scenarios, which potentially impact many single facilities, have to be considered. Even though the OSH management, the control of Major Accident Hazard (MAH) are traditionally considered separately in practice, in legislation and in research, their integration is an emerging topic for industrial clusters. The objective of the present work is to integrate OSH risk assessment with issue characterizing the spatial-based MAH assessment. At plant unit level, information about damage area, derived from MAH, will be combined to the exposure time of a worker in a specific plant area; thus, the personal risk for each job profile may be derived and added in the OSH risk matrix. A simplified method has been developed, considering the available information and the assumptions. The proposed algorithm aims to assure the consistency between the OSH risk assessment document and the MAH ones. For each job profile, a risk map, which combines severity, exposure and probability, could be evaluated. The test site for the proposed method is a large petrochemical park, which features eight independent opera-tors, 1000 hectares area, and about 1500 employees and 1500 contractors
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
