The influence of the binder viscosity on the laboratory short term aging
No full textThe plant mixing temperature and the field work condition of Warm Binders are not generally the same of those adopted with
traditional and modified ones. This Difference makes RTFOT procedure and temperature (163°C) potentially not
representative of the real aging affecting. Consequently the binder durability evaluation and the performance prediction,
introduced by EN 12591 and estimated after RTFOT, could result affected by inappropriate short term aging procedure.
The main purpose is the evaluation of a new RTFOT procedure based on binder viscosity influence, that justifies the
appropriate laboratory conditions to simulate the effective short term aging during mixing and compaction
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
The organisational performance of national swimming federations in Mediterranean countries: A comparative approach
No full textInternational audiencehis paper confronts the basic questions involved in the measurement of the performance of national sport organisations through a specific approach conceived and carried out for national swimming federations in four Mediterranean countries (Italy, Greece, Portugal and Spain). In the past there has been a number of studies assessing the effectiveness or the performance of NSOs (national sporting organisations/national governing bodies/national sport federations), but these were predominantly descriptive, specific to a particular point in time, and were not related to the establishment of a stable measurement system for management control. Performance is viewed here, in a broad sense, as the ability to acquire and process human, financial and physical resources to achieve the goals of the organisation. To measure a multidimensional performance we propose to use a specific model with a systemic approach (applied from Madella, A. (1998). La performance di successo delle organizzazioni‐Spunti di riflessione per gestire efficacemente le società di atletica leggera. Atleticastudi , 101–112). This approach combines at the same time, input and process variables and output measures. The final data collected, incorporate five basic dimensions: human resources, finance, institutional communication, partnership and inter‐organisational relations, volume and quality of services, and athletes’ international performance. An analysis of the global performance of each federation is illustrated. Finally interviews with key actors are used to identify some of the principal factors of success of performance
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
