    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    Digital Video Interaction to support frontal lecturing inmultiple platforms of internet based communication

    This paper reports on an active role played by the students of the Digital Communication degree at the School of Sciences of the University of Milan, Italy, to develop e-learning supports both in their university and in the high schools where they studied previously. Creating and maintaining portal websites, discussion forums, learning objects to be exchanged, and more recently, an interactive video-journal that’s accessible on mobile phones and WEB-TV, have enhanced the learning process both in the University of Milan and in the aforementioned high schools, through the use of new digital technologies in order to supplement the traditional teaching methods in the classroom, that are bound to the dimensions of space (location) and time. Explanations and feedback regarding the lectures in class are made available through videos uploaded to our WEBCEN server in the LCAD University Research Laboratory, while teaching support is implemented by a community effort which involves teachers as well. Results achieved are measured through the reduction in the amount of insufficient marks among the students at the end of each Academic Year. Interactive Digital Television (IDTV) has opened new frontiers for the diffusion of e-learning support platforms, and when internet connection and internet-based content will also be available on IDTV networks starting from the Spring of 2009, the amount of interaction will reach a new and more significant dimension. Hypertexts will also play a key role in the reachability and fruition of our e-learning support and Interactive VideoJournal applications in multiple platforms with internet connection capability

    Standard and ontologies perspectives in building and planning learning future

    Recent developments in ICT offer more opportunties to improve and widen communications with an obvious impact on E-learning methods and the distribution of educational content. E-learning represents a new concept of education and leads to a common standard to implement interoperability and to share resources. Teachers and students do not have to learn the use of different platforms, thus saving time, money and hard work. Moreover, it is more complex to manage different platforms than a single one. Finally, the adoption of such a standard allows economy of scale by allowing teachers to share contents created with different authoring systems. ADL Scorm is the more credited standard allowing the teacher to interact with other material from an existing course. Along this line of integrating services, it emerges the innovative role of the Semantic Web, which aims to make web-based information services universally understandable and reusable. E-learning standards and the semantic web are strictly related, because they both aim to share and reuse information through the web. Moreover, since ontologies are a significative component of the Semantic Web, both of them will influence the development of new generation elearning systems. At the University of Milano are experimenting both concepts while accomplishing the new version of WEBCEN, www.webcen.unimi.it, an in-house educational environment that manages the four Undergraduat Curricula offered in the Information Technology Are

    Appropriate Similarity Measures for Author Cocitation Analysis

    We 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

    We 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 text
    We 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
