Planning Support Systems: Progress, Predictions, and Speculations on the Shape of Things to Come
In this paper, we review the brief history of planning support systems, sketching the way both the fields of planning and the software that supports and informs various planning tasks have fragmented and diversified. This is due to many forces which range from changing conceptions of what planning is for and who should be involved, to the rapid dissemination of computers and their software, set against the general quest to build ever more generalized software products applicable to as many activities as possible. We identify two main drivers – the move to visualization which dominates our very interaction with the computer and the move to disseminate and share software data and ideas across the web. We attempt a brief and somewhat unsatisfactory classification of tools for PSS in terms of the planning process and the software that has evolved, but this does serve to point up the state-ofthe- art and to focus our attention on the near and medium term future. We illustrate many of these issues with three exemplars: first a land usetransportation model (LUTM) as part of a concern for climate change, second a visualization of cities in their third dimension which is driving an interest in what places look like and in London, a concern for high buildings, and finally various web-based services we are developing to share spatial data which in turn suggests ways in which stakeholders can begin to define urban issues collaboratively. All these are elements in the larger scheme of things – in the development of online collaboratories for planning support. Our review far from comprehensive and our examples are simply indicative, not definitive. We conclude with some brief suggestions for the future

Networked Living: a new approach to teaching introductory ICT
The course T175 Networked Living is a 300 hour, multiple media, distance learning course offered by the UK
Open University. The first presentation of the course, in 2005, attracted over 1600 students. T175 introduces
students to general concepts of information and communication technology in a range of contexts, including:
communication and identity; entertainment and information; and health, transport and government. It is an
introductory (level 1) course for a variety of bachelors’ degrees, including the BSc programmes in: Information
and Communication Technology; IT and Computing; and Technology; as well as the BEng engineering
programme. The course was designed with a focus on retention of students and preparing them for further study.
Student workload and pacing was carefully planned and there is a significant study skills component. The course
uses a range of media, including: text, audio, computer animation and other software, and a website. Active
learning is encouraged by means of activities, online quizzes, animations, spreadsheets and a learning journal.
Continuous assessment is carried out via a mix of multiple-choice assignments (to test factual and numerical
skills) and written assignments (which include elementary research into new topics). The course culminates with
a written end-of-course assessment. This includes a major reflective component, as well as more traditional
questions designed to test knowledge and understanding

E-learning for Networked Living
Networked Living is a Level 1 course in Information and Communication Technologies (ICT) offered by the UK Open University. The first two presentation of the course, in 2005 and 2006, attracted over 3000 students between them. Networked Living introduces students to ICT concepts and issues in a range of contexts. The course adopts a blended learning approach, using printed texts, web resources, DVD and computer conferencing.
All the above media are used where appropriate to support students' learning. About 60% of the material is print-based – teaching texts, together with selected third-party articles. About 20% is web-based – using a comprehensive course web site, but also requiring students to find and use third-party sites. The remaining 20% is based on offline computer resources (e.g. spreadsheets) and collaborative activities using computer conferencing.
The course web site contains short animations, quizzes and several interactive activities where students contribute information and commentaries, and can then see the collated contributions of other students. The DVD contains longer animations, simulations and software. Computer conferencing is used for tutor-group and whole-cohort conferences, and for online tutorials, with both asynchronous and synchronous discussion. The course web site provides a new, shareable 'online journal' facility, where students can record their work for the course.
This paper discusses the various e-learning elements of Networked Living, based on the first two presentations of the course. The paper considers how e-learning can be combined with printed resources to create a successful blended learning experience for students
Decision Support Tools for Cloud Migration in the Enterprise
This paper describes two tools that aim to support decision making during the
migration of IT systems to the cloud. The first is a modeling tool that
produces cost estimates of using public IaaS clouds. The tool enables IT
architects to model their applications, data and infrastructure requirements in
addition to their computational resource usage patterns. The tool can be used
to compare the cost of different cloud providers, deployment options and usage
scenarios. The second tool is a spreadsheet that outlines the benefits and
risks of using IaaS clouds from an enterprise perspective; this tool provides a
starting point for risk assessment. Two case studies were used to evaluate the
tools. The tools were useful as they informed decision makers about the costs,
benefits and risks of using the cloud.Comment: To appear in IEEE CLOUD 201
THE DECISION SUPPORT SYSTEMS FOR THE INFORMATION SOCIETY (i-Society)
The globalization process needs exact information flows that should be collected in due time. The Information Society ensures the communication between people with different expertise from various geographical areas that have similar interests. The increase of the companies’ activities leads implicitly to the increase of the volume and the complexities of databases, as well as the continuous modernization of the integrated information systems in order to collect the information in due time, that is requested by the decision takers and the frequent use of DSS. The paper presents the DSS structure, the main facilities offered by the associated software products, an evolution of the databases technologies, as well as a list of the program products used to process the statistical data and data mining in order to obtain the main sources of information that is necessary to take decisions.Information Society (i-Society); Data Base; Information Systems; Decision Support Systems (DSS); Statistical Package, Portal technology
Research Objects: Towards Exchange and Reuse of Digital Knowledge
What will researchers be publishing in the future? Whilst there is little question that the Web will be the publication platform, as scholars move away from paper towards digital content, there is a need for mechanisms that support the production of self-contained units of knowledge and facilitate the publication, sharing and reuse of such entities.

 In this paper we discuss the notion of _research objects_, semantically rich aggregations of resources, that can possess some scientific intent or support some research objective. We present a number of principles that we expect such objects and their associated services to follow
Spreadsheets and OR/MS Models: An End-User Perspective
In 1986, Bodily stated that practitioners could use spreadsheets to model management science/operations research (OR/MS) problems. We surveyed OR practitioners to determine the extent of implementation of these OR/MS problems in a spreadsheet environment and found that end users are solving OR/MS problems using spreadsheets across many functional areas of business, though in varying degrees. Some areas show higher use than others and spreadsheet models are being used to implement various OR tools in a pattern very similar to their use in the nonspreadsheet environment
