Accessibility Is in the Eye of the Beholder

According to the U.S. National Center for Education Statistics, 19% of undergraduates report having a disability. Many of these students access our libraries in person or online. While theological and academic librarians recognize the need to accommodate people with disabilities, librarians without disabilities might not be aware of ways in which their library places obstacles in the way of those with disabilities, such as computers that cannot have the font color or size changed or steps but no ramps for wheelchairs. This essay describes issues for patrons with disabilities in accessing library services and resources. There are several ways to improve the accessibility of libraries. This essay highlights challenges for those with visual, auditory, and mobility disabilities and describes ways to address these challenges and thus give those with disabilities a more equitable, inclusive library experience.

MatchVIE: Exploiting Match Relevancy between Entities for Visual Information Extraction

Visual Information Extraction (VIE) task aims to extract key information from multifarious document images (e.g., invoices and purchase receipts). Most previous methods treat the VIE task simply as a sequence labeling problem or classification problem, which requires models to carefully identify each kind of semantics by introducing multimodal features, such as font, color, layout. But simply introducing multimodal features can't work well when faced with numeric semantic categories or some ambiguous texts. To address this issue, in this paper we propose a novel key-value matching model based on a graph neural network for VIE (MatchVIE). Through key-value matching based on relevancy evaluation, the proposed MatchVIE can bypass the recognitions to various semantics, and simply focuses on the strong relevancy between entities. Besides, we introduce a simple but effective operation, Num2Vec, to tackle the instability of encoded values, which helps model converge more smoothly. Comprehensive experiments demonstrate that the proposed MatchVIE can significantly outperform previous methods. Notably, to the best of our knowledge, MatchVIE may be the first attempt to tackle the VIE task by modeling the relevancy between keys and values and it is a good complement to the existing methods.

Reading Speed Performance based on Interface Design Elements for Web Interfaces

The development of technology and internet has contributed to more people viewing on-screen content and an increase the amount of material that can be read directly from a Web-based platform. The transformation from paper-based materials to digital materials on the Web, more or less has affected the readability of the materials in which information presented on the printed and web-based documents is dissimilar. However, only few studies have been carried out on the presentation of information specifically, the readability of the text in web-based platform. Meanwhile, readability is one of the crucial aspect of Web usability and could affect the success of a website. The speed of reading is regarded as a good measure of readability. Therefore, this study aims to measure the readers reading speed for web interfaces. This study followed a quantitative analysis method that used experiments to collect data and involved university students as the test subjects. A Web-based Reading Speed Test System (RSTS) was developed for data collection and analysis purpose. The findings of this study found that the web interface with the combination of blue font color, yellow background color and Arial font type have the highest reading speed. In contrary, web interface that consists of combination black font color, white background color and Arial font type have the lowest reading speed. In addition, the reading speed of male participants was slightly higher than the female participants. To conclude, the results of this study signify that the interface design had a significant impact on the students reading speed for web pages.

Use of PowerPoint Presentation by the Teachers for Instruction in Selected Dental Colleges of Bangladesh

This descriptive type of cross-sectional study was conducted to find out the views of undergraduate dental college teachers about the PowerPoint presentations as instructional media used by teachers in dental colleges of Bangladesh. The study period was from January 2018 to December 2018. The study was carried out among the teachers of all 4 phases of BDS course of 2 government and 2 non-government dental colleges of Bangladesh. Out of 4 dental colleges, 2 were within Dhaka and 2 were outside Dhaka. The sample size was 100 for teachers. Convenience sampling technique was adopted for data collection. Self-administered semi-structured questionnaires using five points Likert scale were used for collections of data from teachers. The study revealed that 72% teachers consider Eye appealing appearance for choosing PowerPoint slides and 58% teachers did not use master slide. For selection of font style, 67% teacher agreed they consider readability, 88% agreed they consider visibility from last bench of classroom to select font size but 61% teacher disagree that they consider background for selecting font color. The study recommended, during the preparation of a PowerPoint presentation by teachers some areas like using the master slide, background, the number of words and lines need attention.

Age-related effects on a novel dual-task Stroop paradigm

The Stroop task is a traditional measure of cognitive control processes, yet results remain mixed when it comes to assessing age-related differences perhaps in part due to strategies participants use to reduce inhibitory control demands required for success on the task. Thirty-three older adults and 34 younger adults completed a Baseline (traditional, single-task) version of Stroop, followed by two, novel dual-task Stroop variants: Color-Dual (maintain secondary count of prespecified font color regardless the lexical content) and Lexical-Dual (maintain secondary count of prespecified word regardless the font color). With regard to Baseline performance, we predicted an Age x Trial Type interaction in which older adults would be selectively impaired on Incongruent trials compared to younger adults, and this prediction was supported. When we added secondary task demands, we predicted a Trial Type x Dual-Task Type interaction in which performance in the Lexical-Dual condition would be worse than performance in the Color-Dual condition. This prediction was also supported, suggesting that having a secondary task that activated the irrelevant stream of information required more inhibitory control. Finally, we also predicted that Age would interact with Trial Type and Dual-Task Type, which was partially supported in response latencies and more definitively supported in error rates. Overall, our results indicate that Stroop performance is differentially influenced by additional dual-task demands that potentially minimize strategy usage, which has implications for both young and older adult Stroop performance.
