Integrating security services into computer supported cooperative work

This research describes the development of a groupware system which adds security services to a Computer Supported Cooperative Work system operating over the Internet. The security services use cryptographic techniques to provide a secure access control service and an information protection service. These security services are implemented as a protection layer for the groupware system. These layers are called External Security Layer (ESL) and Internal Security Layer (ISL) respectively. The security services are sufficiently flexible to allow the groupware system to operate in both synchronous and asynchronous modes. The groupware system developed - known as Secure Software Inspection Groupware (SecureSIG) - provides security for a distributed group performing software inspection. SecureSIG extends previous work on developing flexible software inspection groupware (FlexSIG) Sahibuddin, 1999). The SecureSIG model extends the FlexSIG model, and the prototype system was added to the FlexSIG prototype. The prototype was built by integrating existing software, communication and cryptography tools and technology. Java Cryptography Extension (JCE) and Internet technology were used to build the prototype. To test the suitability and transparency of the system, an evaluation was conducted. A questionnaire was used to assess user acceptability.

Doing action research in English language teaching:a guide for practitioners

This hands-on, practical guide for ESL/EFL teachers and teacher educators outlines, for those who are new to doing action research, what it is and how it works. Straightforward and reader friendly, it introduces the concepts and offers a step-by-step guide to going through an action research process, including illustrations drawn widely from international contexts. Specifically, the text addresses: •action research and how it differs from other forms of research •the steps involved in developing an action research project •ways of developing a research focus •methods of data collection •approaches to data analysis •making sense of action research for further classroom action. Each chapter includes a variety of pedagogical activities: •Pre-Reading questions ask readers to consider what they already know about the topic •Reflection Points invite readers to think about/discuss what they have read •action points ask readers to carry out action-research tasks based on what they have read •Classroom Voices illustrate aspects of action research from teachers internationally •Summary Points provide a synopsis of the main points in the chapter
