Attenzione alla Responsabilità Sociale di Impresa
No full textIl presente lavoro è diretto a investigare l’evoluzione dell’attenzione alla tematica di Responsabilità Sociale
di Impresa. A tal fine, si è utilizza una metodologia che non risente dei tipici problemi che potrebbero
influenzare i risultati nel caso in cui si utilizzassero le tipiche modalità di ricerca in tema di attenzione,
tipicamente i questionari. Si è invece optato per analizzare l’interesse di una alquanto più vasta platea di
soggetti, osservando i loro comportamenti su internet. In particolare, si sono analizzati due campioni volti
a cogliere l’effettivo interesse alla responsabilità sociale di impresa. Il primo è legata al numero di
visualizzazioni giornaliere della pagina Corporate Social Responsibility di Wikipedia. Il secondo è costituito
da un indicatore sintetico delle ricerche del termine “CSR” effettuate sul motore di ricerca più diffuso al
mondo, ossia Google. Quest’ultima modalità ha il vantaggio di consentire anche di discriminare le ricerche
a livello geografico. I risultati mostrano alcuni spunti alquanto interessanti su cui orientare la futura
ricerca, tenendo conto che l’attenzione è un argomento cruciale per far si che la responsabilità sociale di
impresa possa tradursi anche in un effettivo vantaggio competitivo
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
Analysis and Optimization of a Puffer-type Water Heater
No full textAbstractIn this paper we present the design optimization of a Puffer-type water heater for sanitary water production in residential buildings. The optimization study is performed with the aim to fulfill the design requirements of the heater, i.e. the provided mass flow rate and the outlet water temperature, while minimizing the surface area of the coil characterizing the Puffer and thus reducing the overall cost of the device. The coil diameter and pitch and the diameter of the pipe composing the coil are analyzed in the optimization study. Starting from available correlations providing the heat transfer rate between the sanitary water and the heated water surrounding the coil, a simplified thermal resistance model of the heat transfer process within the heater is developed. The analysis show a significant impact on the overall heat transfer rate between the sanitary water and the heated water when the geometrical parameters of the coil are varied. Using an optimal value of the pitch to pipe diameter of the coil for a given coil diameter in particular, it is possible to maximize the heat transfer rate and thus minimize the size of the coil. As a first step, the optimization study is performed by introducing sizing constraints allowing for sharing the same coil among several types of water heaters. In this case, a reduction as high as 14% of the coil surface area can be obtained, whereas a reduction as high as 23% can be achieved if the optimization is performed free of such constraints
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
