The KB paradigm and its application to interactive configuration

The knowledge base paradigm aims to express domain knowledge in a rich formal language, and to use this domain knowledge as a knowledge base to solve various problems and tasks that arise in the domain by applying multiple forms of inference. As such, the paradigm applies a strict separation of concerns between information and problem solving. In this paper, we analyze the principles and feasibility of the knowledge base paradigm in the context of an important class of applications: interactive configuration problems. In interactive configuration problems, a configuration of interrelated objects under constraints is searched, where the system assists the user in reaching an intended configuration. It is widely recognized in industry that good software solutions for these problems are very difficult to develop. We investigate such problems from the perspective of the KB paradigm. We show that multiple functionalities in this domain can be achieved by applying different forms of logical inferences on a formal specification of the configuration domain. We report on a proof of concept of this approach in a real-life application with a banking company.

From Offshore Operation to Onshore Simulator: Using Visualized Ethnographic Outcomes to Work with Systems Developers

This paper focuses on the process of translating insights from a Computer Supported Cooperative Work (CSCW)-based study, conducted on a vessel at sea, into a model that can assist systems developers working with simulators, which are used by vessel operators for training purposes on land. That is, the empirical study at sea brought about rich insights into cooperation, which is important for systems developers to know about and consider in their designs. In the paper, we establish a model that primarily consists of a ‘computational artifact’. The model is designed to support researchers working with systems developers. Drawing on marine examples, we focus on the translation process and investigate how the model serves to visualize work activities; how it addresses relations between technical and computational artifacts, as well as between functions in technical systems and functionalities in cooperative systems. In turn, we link design back to fieldwork studies

A mathematica‐based CAL matrix‐theory tutor for scientists and engineers

Under the TLTP initiative, the Mathematics Departments at Imperial College and Leeds University are jointly developing a CAL method directed at supplementing the level of mathematics of students entering science and engineering courses from diverse A‐level (or equivalent) backgrounds. The aim of the joint project is to maintain — even increase ‐ the number of students enrolling on such first‐year courses without lowering the courses’ existing mathematical standards

Using technology in service delivery to families, children and young people

This paper provides an overview of how the innovative use of technology can add value to service delivery in organisations working with families, children and young people.Key messages:Most Australians have access to the Internet and use mobile devices to connect from anywhere, at any time. Research suggests that even isolated and marginalised groups are using technology in their everyday lives.For some groups (e.g., young people), technology may be their preferred method of communication.There appears to be a difference between how people are using the Internet (regularly, from anywhere, connecting with social networks, investigating services) and how some organisations are engaging with it (infrequently, in one direction).Technology works best when used to augment or improve existing services for clients, or to offer innovative approaches to existing services.Technology can be used in diverse ways for organisational improvement (e.g., remote access, staff training, professional development) or client services (e.g., online counselling, SMS appointment reminders, access to resources).Using technology does not necessarily involve large monetary investments or reinventing the wheel in terms of policy and procedures. Often it is a matter of adapting and refining existing services and policies to better suit the online world.Incorporating technology into services takes time, and will need continued assessment and refinement to be successful

Mentoring Former Prisoners: A Guide for Reentry Programs

Few social programs have attempted to provide high-risk adults -- and, particularly, former prisoners -- with mentors. And thus there are few resources that offer practical advice and recommendations for mentoring this population, given its distinct needs, assets and challenges. While much remains to be tested and learned, this manual draws on the experience of the 11 sites involved in P/PV'sReady4Work prisoner reentry demonstration, as well as established best practices in the mentoring field, to provide guidelines for practitioners who are interested in developing a mentoring program to support former prisoners and enhance the effectiveness of other reentry services, such as employment and case management services.The guide was originally published by the US Department of Labor in November 2007 under the title Mentoring Ex-Prisoners: A Guide for Prisoner Reentry Programs. However, because of growing interest in establishing mentoring programs as part of larger reentry efforts around the country, P/PV decided to reissue the guide, along with updated information related to P/PV's evaluation of Ready4Work (particularly findings published in Mentoring Formerly Incarcerated Adults, 2009.

Elementary School Children\u27s Perspective of Interactive Activities in English Class in China

Much research regarding implementation of interactive English activities in Chinese elementary schools has been conducted. Missing, however, are studies from children’s perspectives. To garner an initial look into young Chinese students’ perspectives regarding English learning, a 41-question survey was conducted to investigate their perceptions of interactive activities. Sixty-seven participants (30 boys and 37 girls) between ages nine and twelve were included. Results showed that 88% of these students want interactive activities because they can learn happily, and 79% reported that the interactive activity help improve their test scores. Indeed, most students agreed that interactive activities enhance relationships among students, teachers, and parents. However, 19% of the students complained that interactive activities are a waste of time. Overall, students mostly lauded interactive activity but with caveats, namely one of a learning curve. Indeed, Chinese students may appreciate interactive learning, but many students may require years adapting themselves to such in-class structure

Blog-based online journals for English As A Second Language learners

The research on the use of blogs as online journals was carried out with a group of twenty five Form Four students in a secondary school in Kuantan, Pahang. The aim of the research is to find out the effects of blogs as a tool in developing writing in English as A Second Language. The instruments include questionnaire, semi-structured interviews and analysis of the blogs content. The research covered students’ perspectives of blogs as the medium for online journals, the effectiveness of blogs as a tool to assist students’ writing skill and to what extent blogs could help students to enhance their writing skills. From the findings, it is discovered that there is a positive impact on the development of students’ writing throughout the research as gained through the instruments. From the research, the students claimed that blogs is an interesting medium for them to write their journals as compared to writing in their log books. Blogs also could help them developed their writing skill in English Language; and through the various features in blogs, students were able to write more effectively
