A new communication aid for the handicapped
No full textPeople with bad speech impediments are unable to communicate rapidly and effectively. A review is given of the various categories of speech . impediment and the range of communication aids available. This shows that although many communication aids of various forms are available, a need exists for a highly portable device which can be carried around and used anywhere and which preserves the interactive nature of normal conversation. Recent advances in microelectronics have made such a device possible. This thesis describes an aid comprising a small hand held keyboard and an electroluminescent:display which can be worn in a top pocket so that it is positioned close too the 'talker's' face. This arrangement enables one to look at the person talking and it allows the message to be read whilst it is being typed,' rather than waiting until the end as with a written note.The display needed to be)read across a normal sized room and yet its size was strictly:limited. The solution adopted was to use a display similar to the 'newscasters' used on some buildings, with the. letters of the message moving smoothly across the display window from right to left. A prototype aid of this form was designed and constructed, using a display matrix of Light-Emitting Diodes.' Experiences with this prototype indicated that the idea was sound and that a demand existed for such a device. Reading tests, using a computer simulation, showed that a display with smooth motion approximated by moving the letters along one column of the display matrix at a time could be read more quickly -end accurately than one with the motion in steps of one letter at a time. The effect of display length' was investigated and a five- letter display was chosen as a good balance between cost and readability, allowing reading at speeds of between 200 and 300 words per minute with some concentration whilst permitting a high accuracy at typing speeds,:of: 50 to 100 words per minute.Same further improvements have bean made to the design and a small' production run is now being made by the University of Southampton's Wolf car Industrial Unit, for evaluation in operational use.</p
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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 linkWe 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 linkWe 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
