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
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
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
Ontwerpvereisten voor LED-gebaseerde operatielampen
No full textIn March 2012, UZ Jette has announced that they will expand their surgical facility. During this Ph.D. research project, an innovative light and ventilation concept has been developed to reduce post-operative infections. The system is currently patent-pending.
When a patient undergoes surgery, there is still a chance between 1 and 4 that he or she will develop a post-operative infection. Besides pain and discomfort, these infections can lead to hospital re- admission, additional surgical procedures or even death of the patient. Also, these infections lead to increased costs for the patient and health care. One of the measures to reduce the infection rate is the ventilation system which refreshes the air in the operating room. In modern operating rooms, a ”laminar downflow” is installed. Such a laminar downflow system provides clean, cooled air, that descends on the patient from the plenum. However, this laminar flow is perturbed by the surgical luminaire, thus causing turbulent air flows. Post-operative infections may originate as airborne pathogenic particles from outside the protective zone enter the surgical site by these turbulent air flows. To reduce or even eliminate this disturbance of the laminar airflow by the surgical lighting, we propose an integrated concept of an LED-based and automated light source, mounted above a ventilation chamber. This integrated system needs to be as effective as state-of-the-art surgical luminaires. The technological know-how needed to build surgical luminaires, is not described in literature. Instead, this knowledge is part of the intellectual property of the companies that produce them. Therefore, this thesis first develops different tools that are needed to design adequate surgical lighting: both photometric and spectroscopic aspects are taken into account. Using this knowledge, an innovative and patent-pending lighting system is then proposed which will improve patient safety during surgery.status: Publishe
