    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

    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

    Project-based learning in consecutive modules on geotechnics: foundations

    No full text
    Three conditions of effective learning have been reported: active learning by doing, cooperation and teamwork in learning and learning through problem solving, essential to promote creativity and innovative capacity. Project-based learning can help to promote such skills in engineering programs as it allows recreating professional reality and relating fundamental theories and skills of an engineer. High-level thinking and sound judgment is developed through accumulated authentic professional experience by engineers. For engineering students a similar process can be triggered by a teaching environment which enables simulating and stimulating such skills. To prepare better professional and enhance students' employability Civil Engineering students of University of Aveiro, Portugal, have undertaken several modules on Geotechnics where a project based learning model has been used. These group projects included open-ended realistic scenarios tackled using different tools (spread-sheets and software). This paper refers to a module on Foundations. A collaborative project-based learning model was implemented. Students' perceptions on the added value of the project were collected using a questionnaire and are discussed. Most students had attended two modules on Soil Mechanics where a similar learning model was used, but initially they had negative reactions to it. Students report a severe workload; however their estimates match the expected working hours. The model has been evolving in order to optimise the learning and address the students’ feedback

    Promoting problem solving and high order thinking skills in Geotechnical courses

    According to the literature, traditional engineering educational strategies (lectures, lab experiences and homework) have been criticised. On one hand, they inadequately prepare engineering students to engage in collaborative partnerships (essential for the practicing engineer) and, on the other hand, they promote passive learning and contribute to a compartmentalized curriculum. These strategies may not prepare students for the innovative and flexible role of engineers in today’s society. Using non-traditional learning strategies is essential to prepare engineers ready to succeed in their professional life. To contribute to enhancing the problem solving skills and higher order thinking of the graduates in Civil Engineering program of University of Aveiro, Portugal, two complementary courses on Geotechnical subjects have been redesigned using non-traditional learning models: Soil Mechanics I and II. The non-traditional strategies include cooperative and collaborative learning models using team projects or problems. These models have been implemented since 2007/2008. The non-traditional learning strategies used are described and discussed, pointing out how they can contribute to the development of problem solving and high order thinking skills. The students’ reactions to these models are addressed and the strategies implemented to promote their acceptance are presented. To assess the impact of the models implemented three different and complementary strategies were used: students’ feedback during the semester; monitoring of marks; questionnaires at the end of the semester. The evolution of the students’ response to these models is discussed using data collected in the courses. The models have been adapted to overcome some of the difficulties faced during their implementatio

    Project-based learning in Geotechnics: cooperative versus collaborative teamwork

    Since 2007/2008 project-based learning models have been used to deliver two fundamental courses on Geotechnics in University of Aveiro, Portugal. These models have evolved and have encompassed either cooperative or collaborative teamwork. Using data collected in five editions of each course (Soil Mechanics I and Soil Mechanics II), the different characteristics of the models using cooperative or collaborative teamwork are pointed out and analysed, namely in terms of the students’ perceptions. The data collected include informal feedback from students, monitoring of their marks and academic performance, and answers to two sets of questionnaires: developed for these courses, and institutional. The data indicate students have good opinion of the project-based learning model, though collaborative teamwork is the best rated. The overall efficacy of the models was analysed (sum of their effectiveness, efficiency and attractiveness). The collaborative model was found more adequat

    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

    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
