Going Beyond Counting First Authors in Author Co-citation Analysis
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
Factors Influence Reading From Screen of Arabic Textbook for Learning by Children Aged 9 to 13
The problem with e-texts are related to the way texts are displayed on a screen, with multiple and different aspects that affect legibility, making readers prefer to read a paper format rather than e-resources. This research describes the factors that affect the legibility of online texts aimed at obtaining a better understanding of the usability of electronic Arabic texts for learning purposes within the field of electronic reading; mainly reading Arabic texts for students aged 9 to 13. This study sets out three particular aims: (1) building a reading strategy for Arabic schoolbook in both formats electronic and paper format based on users’ cognitive and behavioural processes; (2) defining the influence of three typographical variables that affect reading Arabic texts on a screen (font size, font-type and line length); and (3) studying the efficiency of reading Arabic texts and the related factors impacting the efficiency of reading and comprehension.
Based on the nature of the research questions and objectives, positivism and phenomenology are adopted as the underlying philosophy for this research. The empirical research was divided into three phases; the first phase focused on collecting data about using the internet among students in primary schools by means of a questionnaire. This has helped in the selection of samples and determined the extent of the students’ reluctance to read from a screen. The second phase was to investigate the reading process of school book in two formats [ paper and electronic format] to build reading model based on users’ cognitive and behavioural processes. The third phase was to examine the factors that affect negatively the usability of electronic texts by examining three issues: font size [10, 14, 16 and 18], font type [Arabic traditional, Arial, Times New Roman, Simplified Arabic, and Courier New], and line length [single column and double columns]. Observation was applied as a tool to collect the data.
The study has made a significant contribution to the understanding of electronic reading of Arabic language. This contribution addressed five aspects: (1) Two models of reading process for schoolbook using Arabic language were built according to users’ interaction with the school textbook in two formats ( electronic and paper). These models will not only help define the interaction amongst users and e-books, but will also help designers to understand user behaviour of e-books and thereby to establish the most appropriate functions/features when building an e-book interface. (2) Identify the optimal font size for reading an Arabic script from screen by children aged 9 to 13. (3) Based on collecting data from experiments (2) and (3) and comparing this date with other researches that have done in the same field, new model explains the interaction between three topographical variables [font size, font type and line length] and their relationships with independent variables were provided. (4) Test a new display technique to improve the legibility of reading Arabic online texts by using colour to increase the ability to focus vision when moving from one line to another so as to improve the screen display. And (5) according to quantitative and qualitative several of the rules were recommended for designers and educators to follow when designing and presenting Arabic text on screen.
On the other hand, some recommendations for future research have been derived from this thesis, such as the following. (1) Investigating the effect of the colour factor on improving the legibility of Arabic texts on screen for children, e.g. using different colours to distinguish between dots and vowels. (2) Exploring and developing an e-reading model based on all the factors recorded in the empirical studies in the reading field which will lead to building a theory on e- reading. (3) Investigating the influence of a variable effect reading process and the variables that have a positive or negative impact on it. (4) Applying a model that used colour to increase the ability to focus using different age-range and type of information such as journals or books

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
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
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
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
