In this paper, an explanatory design theory for Financial Market Surveillance Systems is presented, which addresses both user requirements and regulatory demands. The identified general requirements and generated general components of the proposed design theory provides a theoretical foundation for design of implementation of highly flexible and real-time surveillance systems for capital markets.

End-user modifiability allows different users to tailor a system to pursue different tasks, to have different preferences, and to adapt it to changing needs over time. User studies were performed with a system called MODIFIER, an end-user modification component for design environments. These studies helped refine previously hypothesized principles of end-user modifiability and identify new prin...

Combinatorial designs are very effective tools for managing keys in an infrastructure where power and memory are two major constraints. None of the present day wireless technologies takes the advantage of combinatorial designs. In this paper, we have proposed a general framework using combinatorial designs which will enable the participating devices to communicate securely among themselves with...

Biologists are faced with the problem of integrating information from multiple heterogeneous public sources with their own experimental data contained in individual sources. It is difficult for them to choose between the numerous sources without assistance. Interestingly, biologists not only express preferences concerning the sources to be queried but also differ in their strategies i.e. the qu...

Providing computational support to group meetings is a challenge some applications are now addressing. Nonetheless, there are specific areas which need special attention by developers to cover all inherent issues, which can reveal themselves as workflow, interface or context requirements, among other. In the group psychotherapy field of study it is necessary to be careful with both the therapis...

Current systems aiming at facilitating and extending musical expression typically rely on concepts that nonmusicians can hardly comprehend. To attract such users, different interaction metaphors laying outside of the musical domain need to be considered. This study is a step towards the definition of a new class of interfaces for musical expression that targets non-musicians and is centered on ...

People who suffer from Diabetes are required to make frequent decisions on their personal treatment based on results from glucose monitors. Yet the results returned from the devices form only a part of the decisionmaking process. We seek to understand the role that glucose monitors have in patient’s management practices and how technology could support patients’ management further. From a serie...

Nowadays, developers and service providers put a lot of effort on collecting and analyzing user feedback with the purpose of improving their applications and services. This motivates the proposal of new tools to collect and analyze feedback. In our work, we develop a user feedback ontology, aimed at clarifying the concepts of this domain. For that, we follow a goal-oriented methodology to ident...

The generation of design ideas in group discussion is a complex and dynamic process. Some design ideas are accepted; others are rejected; many others are modified and combined. The fluent expression of ideas and the ability to interact and build on representations created by others contributes significantly to the idea generation process. Computerized shared drawing tools support this fluency a...

Given a specication that includes a number of user requirements , we wish to focus on the requirements in turn, and derive a partly dened program for each; then combine all the partly dened programs into a single program that satises all the requirements simultaneously. In this paper we introduces a mathematical basis for solving this problem ; and we illustrate it by means of a simple example.
