Rogers, Neil, Wald, Mike and Draffan, E.A. (2016) Evaluating the mobile web accessibility of electronic text for print impaired people in higher education. In, 13th Web for All Conference (W4A '16), Montreal, CA, 11 - 13 Apr 2016.
The data provided here was gathered by mapping identical or equivalent settings relating to accessibility across three different smartphone devices, namely: the Android, iOS and Windows Phones. This was to provide core settings that if tested a comparison could be made across all three devices.</span
Automatically evaluating the mobile web accessibility of Higher Education electronic texts for print impairments
No full textThe aim of this thesis is to investigate how to automatically evaluate the mobile web accessibility of Higher Education (HE) electronic texts for those with print impairments. The outcome is a master key component referred to as accessibility metadata. This unlocks hidden information that can be presented in human readable form and provides a means to automatically assess the accessibility support offered by mobile device settings, mobile browsers, ereader applications and downloadable formats. This process involves an academic or student searching for, finding, downloading, navigating and reading an electronic text while using a Higher Education Institute (HEI) library web portal on a mobile device. Two research questions are addressed using expert reviews. RQ1: determines four physical and sensory control categories, namely: visual, audio, touch and speech that support automatic evaluation. This also incorporates issues arising for those with dyslexia a form of cognitive impairment. The control categories analysed against user tasks, specific to searching for, finding, downloading, navigating and reading HE electronic texts provides the basis to answer RQ2. The latter investigates how automatic evaluation is achieved through the production of an instrument that provides Barrier Walkthrough (BW) success criteria. This criteria enables a specification to be written for a mobile web accessibility evaluation tool that is incorporated into a wireframe for four mobile web applications and a web service. In the future, the framework can be repurposed to other sectors, from pre‐school tablet content to the use of adaptive mobile technologies by older adults who may experience age‐related disabilities

Classic accessibility checks fail e-readers
No full textEvaluations undertaken for digital materials and technologies that consider accessibility and ease of use for the type of resource – device, software or digital content – tend to be assessed in isolation. In doing so they exclude the importance of the interrelated aspects of accessing eBooks, failing to support the needs of those with print disabilities: such as visual impairment; dyslexia; and/or physical difficulties. Each individual embarking on the process of reading digital texts must: choose an eReading device or application; navigate and access the eBook market-place; decide on or by choice of device or software, accept a type of format; and then interact with the eContent. This paper aims to illustrate how we, by combining a group of accessibility standards, guidelines and criteria, evaluate these facets of eText accessibility using a single review method. The combination of evaluation scores with descriptions has the potential to help users, those supporting the users and those providing or developing content to gain an understanding of accessibility issues that may arise. Since no accessibility guidelines exist specifically for mobile eReader applications, this paper identifies a framework for user-centred accessibility criteria, incorporating all aspects of eReading that could enhance existing guidelines
Evaluating the mobile web accessibility of electronic text for print impaired people in higher education
No full textThe aim of this extended abstract is to demonstrate a framework that provides a novel solution for evaluating the mobile web accessibility of electronic text for print impaired people in Higher Education (HE). The current framework explores over 500 device settings. Furthermore, the scope of this research is outlined alongside two research questions. The paper then concludes by suggesting the potential impact this research could have on existing standards, the public availability of metadata and guidelines, and the automatic generation of personalised eTexts as per user need
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
