Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Train-For-Life : on-line interactive training for industry learners
No full textLearning a topic online via Massive Open Online Courses (MOOCs) has gained a lot of popularity due to their scalability and efficiency of knowledge distribution. However, participating in these courses usually means fully committing to the course for at least a few months in some cases. Providing engaging online education is a challenger for industry/non-academic trainees mainly due to their lack of time. In this paper, we describe a practical experience of online learning for non-academic audience in transport, logistics, security and safety industry. The proposed training courses are designed to be short, flexible and interactive to keep the trainees interested and engaged with the content. During any courses the trainees were challenged with different interactive tasks to emphasis on some important points.
Results show that more than 90% of the trainees managed to complete the training parts of the courses they are registered to do and enjoyed their experience
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
From source coding to MIMO : a Multi-Level Unequal Error Protection
No full textIn this paper, unequal error protection (UEP) on different levels of the transmission system is proposed. Starting from the source coding level, two priority layers are produced, high priority (HP) and low priority (LP). At channel coding, each priority layer is turbo encoded with a coding rate that reflects its importance. For modulation, a more immune modulation mode is used to modulate the HP bit stream. Finally at the transmission level, a 3 × 3 MIMO is used, where more transmit antennas and time slots are offered to HP data. This arrangement of inequality over several levels increases the flexibility of the UEP system and leads to a better performance. Results show that the proposed system outperforms other semi-unequal and equal error protection systems over a wide range of channel signal-to-noise ratio (SNR), especially at low SNR values
