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

No full textVariations 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
Experimentation and challenge: on-line criminology at the University of Bologna (Italy)
No full textApproximately since the second half of the 1990s, it has been heatedly debated in Italy as to how and whether data communication networks can offer new learning contexts.
In this first phase of intellectual turmoil and experimentation at various levels which, in my opinion finished April 17th, 2003 when a decree was issued, signed by both the Minister of Education and University and the Minister of Innovation and Technology which also establishes Open Universities in Italy, my three year experience while in charge of an on-line course on criminological topics carried out in an undergraduate course for “Security and Social Control Operators” (Faculty of Political Science “Ruffilli”, University of Bologna).
I believe that this on-line course represented a real challenge for four different reasons:
1) it was inserted in the syllabus of a three year undergraduate course which had recently been established and was the first university course in Italy intended for the training of operators to carry out an activity which calls for being able to manage modern investigative, security and control strategies;
2) it dealt with the teaching of criminology and it is useful to emphasize that, in Italy, criminology has a difficult time freeing itself from similar disciplines (legal medicine, criminal law, sociology, psychology), even while knowing that it has to maintain a good relationship with them;
3) it dealt with one of the first on-line courses activated at the Faculty “Ruffilli”;
4) it was intended for the university training of the Marshals of the Carabinieri.
The on-line teaching activities I organized and managed were preceded by a lesson requiring physical presence and were accompanied by my availability to receive the students face-to-face numerous times each week.
The course, in its three years of activation, had the overall participation of 418 students; it was received with favour and interest on the part of the participants and also gave me the possibility to reflect on the potential and the limits of this teaching method.
On the one hand, I feel the use of data communication technology is fundamental in liberating teaching from physical presence and established schedules in order to give university students the possibility of personalizing their educational courses on the basis of their needs as well as allowing them to take advantage of university teaching as lifelong learning, also reaching sectors of the population which, for various reasons, find it impossible to take part in “traditional physical presence university education”.
On the other hand, I think that the use of e-learning should be concentrated on those areas in which there are major advantages and which would therefore be used strategically for specific pedagogic ends. In fact, I have realized that, if one wants a high quality on-line course, it is necessary to dedicate a lot of time to it, much more in comparison to a traditional course requiring physical presence. A remarkable technological and human resource investment is necessary involving a large amount of change and, more precisely, challenges which, perhaps, not everyone is ready to face
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
