Dyslexics are different
Get PDFDyslexia is a universal reading difficulty. It can be found in all countries, cultures and languages: Arabian, European, Chinese, etc. However, everybody is different. Dyslexic individuals are different too. They face different problems while reading. Some of them may not understand what is written, while others may omit, transpose or alter letters while reading a word. And the same at the word level. The aim of this research is to overcome these problems by providing each dyslexic individual with the appropriate learning to improve his/her reading. This may also result in improving other aspects of their difficulties: such as spelling, self-esteem, etc. To do this,the research will follow three stages:
• Diagnosing a dyslexic child to identify their dyslexic type,
• Developing a training system to provide a series of learning exercises tailored to the needs of the individual dyslexic child.
• Evaluating the proposed system in terms of learning and satisfaction
HCI: Adaptive learning For Dyslexic users
No full textDyslexia is a lifelong reading difficulty that exists everywhere regardless of an individual's language or culture. They face various difficulties in reading, writing and spelling. Whilst it is impossible to find two individuals with dyslexia with exactly the same difficulties, most current research treated them similarly. Further, the manifestation of dyslexia is affected by the language's structure and orthography. Because of the lack of research on Arabic dyslexia, especially on the benefits of adaptive e-learning in this domain, this research aimed to understand the impact of adapting the e-training material to the characteristics of a learner with Arabic dyslexia on their reading performance, satisfaction and behaviour. The focus was on Arabic dyslexia types as the learner's characteristic because they reflect the reading difficulties they face with reading being their main problem.
We first analysed the literature on Arabic dyslexia and current e-learning systems that support individuals with dyslexia to understand dyslexia and to identify the weaknesses in these systems. Next, we conducted two controlled experiments to understand the effect of matching the training material to one of the Arabic dyslexia types on the learner's reading performance, satisfaction and behaviour and to validate the developed system and tools. Because each experiment focused on vowel letter dyslexia and short vowel dyslexia, we designed a dyslexia diagnostic test to determine the Arabic dyslexia type that a learner with Arabic dyslexia has. In each experiment, we measured reading improvement and learner satisfaction and observed the learner's behaviour. The findings showed that the reading of learners with Arabic vowel letter dyslexia and short vowel dyslexia improved similarly and that all learners were highly satisfied with the system.
From these two experiments, we discovered a new common Arabic dyslexia reading difficulty named short vowel dyslexia. Therefore, we noticed that the literature and practice were inconsistent. So, we designed a questionnaire to understand dyslexia in practice from the perspective of special education teachers. We found that visual dyslexia is also common among learners with Arabic dyslexia. Therefore, the final experiment targeted vowel letter dyslexia and visual dyslexia taking into account lessons learned from the first two experiments. In this experiment, the training material was adapted to the learner's Arabic dyslexia type (vowel letter dyslexia and visual dyslexia). We can conclude that adapting training material to learner's Arabic dyslexia type improved their reading and the learners were highly satisfied in both conditions and no opportunity to discriminate between them. On the other hand, we cannot conclude that what has been learned can be generalised to other words with similar features. Finally, learners were happy and engaged as they learned and they followed some good practices to improve their learning
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
