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
Local cooling in spinal cord injury
No full textEight patients with acute spinal cord injury at different levels were treated by local cooling. Early laminectomy was performed and the subdural space was irrigated with saline at 5°C for about two hours. In addition to this treatment, five patients, after closure of the operative wound, received local epidural cooling that was prolonged for a few days. All patients before treatment had a complete loss of function of the spinal cord below the injured segment. Four of these regained some sensory and motor functions and two were able to walk. Somatosensory cortical evoked responses were consistent with the results obtained, thus demonstrating their prognostic value. The clinical application of local spinal cord hypothermia in order to minimize the catastrophic effects of spinal cord trauma is discussed. The results obtained in these eight patients agree with the several experimental observations and seem to justify the application of this procedure to human beings
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
Public Engagement, Local Policies, and Citizens Participation: An Italian Case Study of Civic Collaboration
Full text linkSince the 1990s, the theme of participation has come to the fore in international debates regarding at least three critical issues: the relationship between representative democracy and deliberative democracy and the possibility of citizens’ empowerment through their involvement in policy making; the role of communication and of digital media in promoting new forms of participation; the feeling of disaffection toward politics and of democratic deficit. What we observe is a proliferation of experiences of both bottom-up and top-down enhanced forms of civic engagement. Our article focuses on “public engagement.” We analyze the civic collaboration policy promoted by the Municipality of Bologna (Italy) in the frame of “collaborative governance” of the commons, based on civic involvement and governance transparency. Civic collaboration is characterized by a mixed communication ecology. We focus on the inclusiveness of this form of public engagement with local policies and on the role of digital media in supporting citizen’s engagement. Civic collaboration emerges as a new, interesting frontier in top-down enhanced participation in local policies. We are currently witnessing some promising changes in the boundaries of participation, in civic practices and competencies. In conclusion, we argue that the concreteness of the projects of civic collaboration can enhance citizens’ trust in the municipal administration, but we wonder whether it is likely to become a substitute for fuller citizen participation in local governance and whether it could also foster a removal of the controversial dimension of the political
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
