No full textSicily monthly high resolution solar radiation climatologies and comparison with future projections
No full textWe developed a methodology to estimate solar radiation climatologies starting from a network of global radiation and/or sunshine duration records and a digital elevation model and applied it to a data set of 41 Sicilian global radiation records covering the 2002-2011.
All records were subjected to quality and homogeneity control. Moreover, the monthly record were subjected to a procedure aiming at estimate missing data.
The first step of the methodology consists in calculating global radiation monthly normals for all station sites or estimating them from sunshine duration normals, when global radiation data are not available.
The second step consists in estimating, the bias due to shading and adjusting the normal values in order to make them representative of un-shaded sites.
The third step consists in interpolating shading-bias-adjusted global radiation normals onto a 30 arc-resolution regular grid. This global radiation normals are then decomposed into the direct and diffuse components. Atmospheric turbidity is then evaluated over the same grid by means of the direct component obtained from shading-bias-adjusted global radiation.
The last steps consists in calculating direct, diffuse and reflected components of global radiation for any grid-cell, taking into account its slope and aspect and considering shading from the cell itself and from the neighboring cells. Knowing the direct, diffuse and reflected components, the global radiation can easily calculated by their sum.
This procedure will be presented and the resulting climatologies will be compared with those obtained from future projections (ENSEMBLES RCMs) with the objective to compare modelled and observed radiation climatologies
Report on future evolution of sunshine duration and solar radiation over Sicily - Work package : WP6 – ENERGY – TASK 6.6 : past and future solar radiation estimation for Sicily
No full textThis report describes the activities performed by ISAC-CNR to produce Deliverable 6.13 of the
ECLISE Project - Future evolution of sunshine duration and solar radiation over Sicily. These activities
were performed within task 6.6 - Past and future solar radiation estimation for Sicily that also allowed
producing Deliverable 6.12 - Climatology of sunshine duration and solar radiation for Sicily. Both
deliverables were produced on the basis of SIAS (Servizio Informativo Agrometeorologico Siciliano,
one of the users of the ECLISE Project) needing. The deliverable mainly consists of maps reporting
monthly solar radiation climatologies for a number of time periods of 1961-2100 interval
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
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
