This paper is based on a study that was to design and test the usability of a tablet app prototype named NETA (Nota Elektronik Tatabahasa) as an assisting tool in Malay grammar learning process. For this purpose, an app prototype and a questionnaire consist of 26 items was developed based on the literature and expert opinions. Human-computer interface theories, usability theories and ID models such as Fitts Law, ARCS Motivation Model, Gagnes Nine Events of Instruction and the Dick and Carey Instructional Design Model provided a basis for the development of the prototype and the questionnaire items. 40 form one students from a secondary school in the state of Penang, Malaysia filled the questionnaire. The Cronbachs alpha coefficient of the questionnaire was found to be .832 indicating a relatively high internal consistency and reliability of the items. The findings generally show that the NETA prototype helps to engage and motivate student to learn Malay grammar. The results also suggest that there are a number of areas for the NETA prototype to improve and promote the app in a more realistic manner that suits the needs of the students. Several recommendations are also presented for future research.

Reading System

As a significant component of the Human Computer Interface (HCI), automatic lip reading is designed for the purpose of understanding the content of speech by interpreting the movements of the lips. Although performance of automatic lip reading system is easily affected by challenging conditions such as noise, illumination and low resolution, enormous advancements in the relevant fields accompanied with enhancement in computer capability have improved the robustness of the system, making it more adaptable to the real environment. In this paper, we study the field and gives a detailed discussion on the actuality and the developing level of automatic lip reading. We emphatically introduce the feature extraction and recognition model algorithms. We also compare and analyze the various visual speech databases for their characteristics and functions in speech recognition systems. In addition, we describe the challenges and offer our insights into future research direction of automatic lip reading.

This article describes a computer-based writing assistant called REVISE, which implements some “Plain English” guidelines in an easy-to-use, efficient computerized tool. Some existing computer-based writing systems are reviewed and some problems with these systems are discussed, particularly in the area of the human-computer interface. The article describes the design principles that formed the basis of REVISE and how REVISE improves upon some of the difficulties noted in the existing systems. A preliminary evaluation of the effectiveness of REVISE is described. Some limitations of REVISE are discussed as are directions for future research and development on computer-based writing aids.

Microcomputers could help reduce two of the principal fears of the elderly: inadequate income and loss of independence; yet there are indications that the elderly do not use computers very extensively because they see them as too complicated or because some of the physical impairments of advancing age make using standard systems too difficult for them. Previous research has shown a high degree of interest in computers among the aging, even in those over 85; however, the research has not focused on the elderly's special needs in the human-computer interface. Research is required on alternative input devices, such as the touchscreen and voice recognition, on menus and screen design, and on the use of color for coding or display background.

Preliminary Study

Purpose The purpose of this study was to investigate executive function measures as they relate to clinical and academic performance outcomes of graduate speech-language pathology students. Method An observational design incorporating correlations and stepwise multiple regressions was used to determine the strength of the relationships between clinical outcomes that occurred at various time points throughout the graduate program (clinical coursework grades throughout the program and case study paper scores at the end of the program), academic outcomes (graduate grade point average and Praxis II exam in speech-language pathology scores), and executive function (EF) scores (EF assessment scores, self-reported EF scores). Participants were 37 students (36 women, M age = 24.1) in a master's degree program in speech-language pathology at a southeastern U.S. university during the 2017–2018 academic year. Results Findings of this preliminary study indicated that a limited number of objective EF scores and self-reported EF scores were related to clinical and academic outcomes of graduate speech-language pathology students. Conclusion As results of this preliminary study suggest that EF tests may be related to clinical and academic outcomes, future research can move to study the potential role of EF measures in the graduate admissions process in clinical graduate programs such as speech-language pathology.

AbstractSecurity vulnerability in third-party dependencies is a growing concern not only for developers of the affected software, but for the risks it poses to an entire software ecosystem, e.g., Heartbleed vulnerability. Recent studies show that developers are slow to respond to the threat of vulnerability, sometimes taking four to eleven months to act. To ensure quick adoption and propagation of a release that contains the fix (fixing release), we conduct an empirical investigation to identify lags that may occur between the vulnerable release and its fixing release (package-side fixing release). Through a preliminary study of 231 package-side fixing release of npm projects on GitHub, we observe that a fixing release is rarely released on its own, with up to 85.72% of the bundled commits being unrelated to a fix. We then compare the package-side fixing release with changes on a client-side (client-side fixing release). Through an empirical study of the adoption and propagation tendencies of 1,290 package-side fixing releases that impact throughout a network of 1,553,325 releases of npm packages, we find that stale clients require additional migration effort, even if the package-side fixing release was quick (i.e., package-side fixing releasetypeSpatch). Furthermore, we show the influence of factors such as the branch that the package-side fixing release lands on and the severity of vulnerability on its propagation. In addition to these lags we identify and characterize, this paper lays the groundwork for future research on how to mitigate propagation lags in an ecosystem.
