Opening Moves Involved in Text-based Computer-Mediated-Communication (CMC) by Chinese Adults

The development of science and technology has made it not only possible but very convenient for people living in different parts of the world to communicate with each other, thus bringing forth a new form of communication: computer-mediated communication (CMC). Text-based CMC is one of the most popular forms of CMC in which people send instant messages to others in different settings. Since this mode of interaction combines features of both the written and spoken language (Greenfield & Subrahmanyam, 2003), it's of great interest whether it follows the same sequential rule as the telephone conversation. However, compared to telephone conversations, computer-mediated communication has received much less attention, let alone text-based CMC. The existing body of literature mostly focuses on content analysis and linguistic features but neglects the sequential organization of such interaction (Paolillo, 1999; Greenfield and Subrahmanyam, 2003; Herring, 1999). In light of this, this paper examines the opening moves of instant message exchanges among Chinese adults in an attempt to find out the unique features characterizing the way they open an online chat. The framework that was chosen for data analysis was the sequential model proposed by Schegloff for American telephone openings.

An Empirical Analysis of the Effect of Text-Based Computer-Mediated Communication on Communicative Competence

It has been suggested that text-based computer-mediated communication can help learners to use target language both in classrooms and in social contexts.It’s necessary to investigate the effect of text-based CMC on learners’communicative competence by conducting the method of systematic review.The findings implied that text-based CMC settings allowed learners to interact.The interaction provided learners with more opportunities to develop their communicative competence of target language.

Usability and Security of Arabic Text-based CAPTCHA Using Visual Cryptography

Recently,with the spread of online services involving websites,attack-ers have the opportunity to expose these services to malicious actions.To protect these services,A Completely Automated Public Turing Test to Tell Computers and Humans Apart(CAPTCHA)is a proposed technique.Since many Arabic countries have developed their online services in Arabic,Arabic text-based CAPTCHA has been introduced to improve the usability for their users.More-over,there exist a visual cryptography(VC)technique which can be exploited in order to enhance the security of text-based CAPTCHA by encrypting a CAPTCHA image into two shares and decrypting it by asking the user to stack them on each other.However,as yet,the implementation of this technique with regard to Arabic text-based CAPTCHA has not been carried out.Therefore,this paper aims to implement an Arabic printed and handwritten text-based CAPTCHA scheme based on the VC technique.To evaluate this scheme,experi-mental studies are conducted,and the results show that the implemented scheme offers a reasonable security and usability levels with text-based CAPTCHA itself.

A Reading Response to Siegel(2013)

This paper records the author's comments and reflection on reading Siegel's(2013) article on L2 listening instruction.It first summarizes major arguments put forward in Siegel's(2013) article, and then proceeds to review commonly used approaches to L2 listening instruction, after which it examines the discrepancy between research and practice. In the end, the author gives some suggestions for further research.

How Do Patients Prefer to Receive Patient Education Material about Treatment, Diagnosis and Procedures? <br/>—A Survey Study of Patients Preferences Regarding Forms of Patient Education Materials;Leaflets, Podcasts, and Video

Aim: The aim of this study was to explore patients’ preferences for forms of patient education material, including leaflets, podcasts, and videos;that is, to determine what forms of information, besides that provided verbally by healthcare personnel, do patients prefer following visits to hospital? Methods: The study was a mixed-methods study, using a survey design with primarily quantitative items but with a qualitative component. A survey was distributed to patients over 18 years between May and July 2020 and 480 patients chose to respond. Results: Text-based patient education materials (leaflets), is the form that patients have the most experience with and was preferred by 86.46% of respondents;however, 50.21% and 31.67% of respondents would also like to receive patient education material in video and podcast formats, respectively. Furthermore, several respondents wrote about the need for different forms of patient education material, depending on the subject of the supplementary information. Conclusion: This study provides an overview of patient preferences regarding forms of patient education material. The results show that the majority of respondents prefer to use combinations of written, audio, and video material, thus applying and co-constructing a multimodal communication system, from which they select and apply different modes of communication from different sources simultaneously.

系统功能类型学视阈下的语法描写范式——以语气系统为例

随着系统功能类型学理论体系的初步建立,系统功能语法描写逐渐形成了一定的范式。系统功能类型学视阈下的语法描写范式主要体现在五个方面:语法描写基于语篇;采用三维视角;突出自上而下的视角;运用轴线论证的描写模式;探究语言的隐性语法。本文以人际语法中的语气系统为主要例证,对这些描写范式进行逐一说明。
