Agents in Bioinformatics

The scope of the Technical Forum Group (TFG) on Agents in Bioinformatics (BIOAGENTS) was to inspire collaboration between the agent and bioinformatics communities with the aim of creating an opportunity to propose a different (agent-based) approach to the development of computational frameworks both for data analysis in bioinformatics and for system modelling in computational biology. During the day, the participants examined the future of research on agents in bioinformatics primarily through 12 invited talks selected to cover the most relevant topics. From the discussions, it became clear that there are many perspectives to the field, ranging from bio-conceptual languages for agent-based simulation, to the definition of bio-ontology-based declarative languages for use by information agents, and to the use of Grid agents, each of which requires further exploration. The interactions between participants encouraged the development of applications that describe a way of creating agent-based simulation models of biological systems, starting from an hypothesis and inferring new knowledge (or relations) by mining and analysing the huge amount of public biological data. In this report we summarise and reflect on the presentations and discussions

A report on the ULTRLAB's development of online components in NCSL programmes

This report is one of two produced by ULTRALAB forthe National College of School Leadership (NCSL). Here we discuss the research and development of online components of two NCSL programmes. The other report looks at the Talking Heads project, an online community for Headteachers in England. This report considers our work on two NCSL programmes. The new model National Qualification for Headship (NPQH) had its first cohort of learners in March 2001. ULTRALAB was involved in consultancy with the DfES, the writers of the programme materials and the ten regional training providers, in setting up the online elements from September 2000. The online community aspects of NPQH were established using think.com software, with the name Virtual Heads chosen for the overarching national community. The pilot for the Certificate of School Business Management started in February 2002. Our involvement here was to develop the online community and support the tutors in its use.The online community aspects were established using think.com software, with the name Bursars’ Count chosen for the overarching national community

Interactivity in professional online learning: A review of research based studies

Over the last few years, the higher education and the vocational education and training sectors have increased the number of online learning courses available for professionals. Yet, research on e-learning opportunities for professionals has not developed at the same pace. This paper describes the results of a systematic search for research based, empirical studies on professional online learning that examined interactivity and other forms of social learning. Based on four selection criteria (online learning course, professionals, interactivity and research study), the search yielded 18 articles. These were examined first in relation to the characteristics and context of the professional online courses under scrutiny, and second in relation to four levels of interactivity focus in the research. The highest level represents studies where the interactivity was planned, supported and implemented successfully, and the lowest level studies where minimal opportunities for interactivity were available. Overall, although some studies were of a high academic and educational quality, there was little evidence of pedagogical innovations that would give this field of educational research and practice a clear direction for the future

Communication aspects of virtual learning environments: perspectives of early adopters

Virtual Learning Environments (VLEs) are increasingly used in higher education to support communication and collaboration among students. However, there is little research into the effectiveness of VLE communication tools, and how they might be improved. This paper reports findings from interviews with teaching staff at UK universities who were early adopters of VLEs. The interviews revealed how these staff used VLE communication tools, what benefits and problems they experienced, and how VLEs might be improved to provide better support for collaborative learning

A Factory-based Approach to Support E-commerce Agent Fabrication

With the development of Internet computing and software agent technologies, agent-based e-commerce is emerging. How to create agents for e-commerce applications has become an important issue along the way to success. We propose a factory-based approach to support agent fabrication in e-commerce and elaborate a design based on the SAFER (Secure Agent Fabrication, Evolution & Roaming) framework. The details of agent fabrication, modular agent structure, agent life cycle, as well as advantages of agent fabrication are presented. Product-brokering agent is employed as a practical agent type to demonstrate our design and Java-based implementation

A tutorial task and tertiary courseware model for collaborative learning communities

RAED provides a computerised infrastructure to support the development and administration of Vicarious Learning in collaborative learning communities spread across multiple universities and workplaces. The system is based on the OASIS middleware for Role-based Access Control. This paper describes the origins of the model and the approach to implementation and outlines some of its benefits to collaborative teachers and learners

Investigating design features of a computer-mediated communication system

Computer-mediated communication (CMC) is increasingly used in higher education, but it is not without problems. The effectiveness of CMC depends on many factors, including the characteristics of CMC systems themselves. The research reported here therefore aimed to investigate how an educational CMC system might be improved, in order to support learning more effectively. The main context for the research was distance learning at the UK Open University (OU). A two-stage, mixed methods research approach was adopted. In the first stage, interviews and observations were carried out to explore the benefits and problems experienced by users. This revealed two major issues: information overload and lack of social presence. Information overload relates to users’ problems dealing with large numbers of messages. Social presence relates to the need for users to feel connected with each other. The second stage investigated system features aimed at addressing these issues, implemented in a prototype computer conferencing system. Features to address overload included branched message threading and user recommendations. Features to address social presence were ‘résumés’ and instant messaging. These features were evaluated using questionnaires, with several cohorts of students in an OU course. Students expressed approval of the features, although some features were not widely used. Students preferred branched threading to chronological threading because branching helped them to follow ‘conversations’. Students were uncomfortable recommending messages, feeling that the value of a message would vary between people. They were also uncomfortable using instant messaging to contact others whom they did not know. However, the awareness aspect of instant messaging provided a sense of solidarity. The research demonstrated that the problems of overload and lack of social presence are significant, and each has social aspects which must be addressed. Students’ relationships with each other affect whether and how they use the features of CMC systems. We can conclude that particular attention must be paid to the social aspects of online communication, both when designing educational CMC systems and when considering how they are used. To maximise the benefits for learning, students need to feel comfortable with each other online, and there are few short cuts to achieving this

Building capacity in climate change policy analysis and negotiation: methods and technologies

Capacity building is often cited as the reason “we cannot just pour money into developing countries” and why so many development projects fail because their design does not address local conditions. It is therefore a key technical and political concept in international development. Some of the poorest countries in the world are also some of the most vulnerable to the impacts of climate change. Their vulnerability is in part due to a lack of capacity to plan and anticipate the effects of climate change on crops, water resources, urban electricity demand etc. What capacities do these countries lack to deal with climate change? How will they cope? What steps can they take to reduce their vulnerability? This innovative and high-profile research project was part of a larger project (called C3D) and conducted with non-governmental organisations in Senegal, South Africa and Sri Lanka. The research involved several participatory workshops and a questionnaire to all three research centres
