    Going Beyond Counting First Authors in Author Co-citation Analysis

    Full text link
    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

    Full text link
    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

    Dispelling the Myths Behind First-author Citation Counts

    Full text link
    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

    Graduate Festival Academic Poster Competition Winner 2014

    The poster examines whether a touch screen smart phone is faster to use in either portrait or landscape orientation. It shows that a phone is faster to operate in landscape orientation when operated with the index finger and that targets in the middle of the screen are fastest to interact with, followed by targets at the bottom/top or right/left of the screen. The results can be used to inform interface design of mobile applications and are part of my preliminary PhD research into improving the operation of touch screen smart phones. Rationale A research poster should be a greatly simplified version of your paper with as little text as possible. Rather than using text and tables, try to explain your research using imagery and boil it down to only the most important aspects. Ideally you can tell a story, starting with a problem, followed by your approach and ending with your results and conclusion. The people looking at your poster are most likely conference attendees in their coffee break looking for something to "read" while munching away on free cake - not super-focussed researchers scavenging the library for exact information. Therefore, you should offer them something that looks nice and is easy to digest. Once you've got people interested, they are likely to download your paper afterwards and read the full story. Success! Posters are extremely useful to help you express your research in a more simplified manner than your probably pretty complicated paper. It will force you to be precise and concise, allowing people not knowledgeable in the field to understand your work. Reading the above I could have certainly improved my poster in a few areas, but altogether I think it has turned out quite nicely

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    No full text
    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

    Improving one-handed interaction with touchscreen smartphones

    Full text link
    One-handed operation of touchscreen smartphones presents challenges such as hard-to-reach targets and the thumb occluding the interface. There are two main approaches to address these challenges: Modification of the graphical user interface (GUI) and extension of the device's input modalities using its sensors. Previous work has presented techniques addressing a specific problem in isolation, but has failed to provide one solution which tackles all main challenges of thumb interaction together. This thesis examines whether this can be done. To establish the background, the thesis finds that users prefer convenience over efficiency and confirms that they predominantly use one hand. To detect mode of operation, the thesis presents an approach to classify a user's finger with a high degree of accuracy using a single touch. Following the first research avenue, the thesis presents a thumb-optimised GUI that increases usability and efficiency of one-handed website operation. Following the second avenue of research, the thesis presents a novel one-handed input technique for smartphones, using a set of three off-screen gestures. Both approaches address the most common problems of one-handed smartphone operation via the thumb largely successfully, but fail to completely solve the problem of interface occlusion. The thesis adds to the literature in the field of visual perception, input classification, GUI optimisation, and input techniques. Readers learn that visual search strategies of the desktop world may also apply to the mobile world and that eye gaze position may have a greater impact on target acquisition time than Fitts's law. The one-touch finger classification technique provides an additional layer of context and new opportunities for improving the human-machine dialogue. The thumb-optimised GUI presents practitioners with a potential blueprint for translating classical WIMP UI elements into thumb-friendly touch interfaces while the novel input technique provides a new layer of complexity for off-screen interaction
