As knowledge discovery (KD) matures and enters the mainstream, there is an onus on the technology developers to provide the technology in a deployable, embeddable form. This transition from a stand-alone technology, in the control of the knowledgeable few, to a widely accessible and usable...

When planning and designing a policy intervention and evaluation, the policy maker will have to define a strategy which will define the (conditional independence) structure of the available data. Here, Dawid's extended influence diagrams are augmented by including 'experimental design' decisions...

This paper draws on Ciborra's insightful concept of xenia (i.e., hospitality) to analyze how successful infrastructural service innovation was managed at the local operations of an international financial services firm. The xenia concept. The xenia concept problematizes the information system...

A conditional simulation technique has previously been presented for variance reduction when estimating rail probabilities. particularly extreme ones. for a wide class of moving-average processes. Here. ve generalize the technique from continuous ro discrete random variables. Two distinct...

The calculation of interval forecasts for highly persistent autoregressive (AR) time series based on the bootstrap is considered. Three methods are considered for countering the small-sample bias of least-squares estimation for processes which have roots close to the unit circle: a bootstrap...

A robust minimax approach for optimal investment decisions with imprecise return forecasts and risk estimations in financial portfolio management is considered. Single-period and multi-period mean-variance optimization models are extended to worst-case design with multiple rival risk estimations...

This paper proposes a new priority scheduling algorithm to maximise site revenue of session-based multi-tier Internet services in a multicluster environment. This research is part of a larger study in support of large-scale online trading systems and, as a result, this case study is chosen as a...

This article examines the interdependency of population-level adaptation (evolution) and individual-level adaptation (learning). More specifically, we assume a trade-off between the two means of adaptation, that is, a higher individual-level adaptation can only be achieved with a reduced...

This paper presents a model, which allows managers to identify the influence of their decisions to the potential innovation activity of the firm by simulation. Systems Thinking methodology has been used to understand the framework of innovation systems and to design and run the simulation model....

In recent years, there has been and continues be an increasing numbers of company mergers and takeovers. However, many of them such as the AOL - Time Warner, merger destroy shareholder value instead of increasing it. Mirivis (1992) and Vansina (1992) observe that approximately half of all...
