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
Investigation Of Feel For 6dof Inputs: Isometric And Elastic Rate Control For Manipulation In 3d Environments
No full textthis paper has been conducted to compare a 6DOF elastic rate controller and a 6DOF isometric rate controller on a 3D object positioning task. With all other factors kept similar, the elastic controller is hypothesised to produce better performance. EXPERIMENT Experimental Apparatus The experiment was conducted using the MITS (Manipulation in Three Space) system developed by the author. MITS is a non-immersive stereoscopic virtual reality environment, based on a SGI IRIS 4D/310 GTX graphics workstation equipped with a Spaceball^TM, an Ascension Bird^TM, CrystalEyes^TM stereoscopic glasses and some self-designed controllers. MITS allows the user to perform dynamic 6 DOF manipulation tasks, such as target acquisition, critical tracking (Jex, McDonell & Phatak, 1966), and compensatory and pursuit tracking (Poulton, 1974) with a variety of 3D objects in various display and control modes. The MITS system automatically records detailed and summary data of user control behaviour and performance score and presents knowledge of results (KR) feedback whenever necessary. In this experiment, the isometric rate control mode is implemented by means of a Spaceball^TM (Model 2003). Th
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
Touch Behavior with Different Postures on Soft Smart Phone Keyboards
No full textText entry on smartphones is far slower and more error-prone than on traditional desktop keyboards, despite sophisticated detection and auto-correct algorithms. To strengthen the empirical and modeling foundation of smartphone text input improvements, we explore touch behavior on soft QWERTY keyboards when used with two thumbs, an index finger, and one thumb. We collected text entry data from 32 participants in a lab study and describe touch accuracy and precision for different keys. We found that distinct patterns exist for input among the three hand postures, suggesting that keyboards should adapt to different postures. We also discovered that participants’ touch precision was relatively high given typical key dimensions, but there were pronounced and consistent touch offsets that can be leveraged by keyboard algorithms to correct errors. We identify patterns in our empirical findings and discuss implications for design and improvements of soft keyboards. Author Keywords Mobile text entry, touch interfaces
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
Modeling human performance of pen stroke gestures
No full textThis paper presents a quantitative human performance model of making single-stroke pen gestures within certain error constraints in terms of production time. Computed from the properties of Curves, Line segments, and Corners (CLC) in a gesture stroke, the model may serve as a foundation for the design and evaluation of existing and future gesture-based user interfaces at the basic motor control efficiency level, similar to the role of previous “laws of action ” played to pointing, crossing or steeringbased user interfaces. We report and discuss our experimental results on establishing and validating the CLC model, together with other basic empirical findings in stroke gesture production.
