A current and significant challenge in the design and implementation of information systems (IS) is to deal with the high failure rate of IS projects. A large number of IS projects fail. Most of these failures are not due to flawed technology, but rather due to the lack of systematic considerations of human and other non-technology issues in the design and implementation processes. In other wor...

We introduce stochastic R&D in the Hotelling model and show that if the technical risk is sufficiently high, all firms focus on the most valuable market segment. We then endogenize technical risk by allowing firms to choose between a safe and a risky R&D technology. In equilibrium, firms either both target the most attractive market with at least one firm using the risky technology or they choo...

in order to have better insight of project characteristics, different kinds of fuzzy analysis for project networks have been recently proposed, most of which consider activities duration as the main and only source of imprecision and vagueness, but as it is usually experienced in real projects, the structure of the network is also subject to changes. in this paper we consider three types of imp...

Implementing information technology projects requires a calculated process to prevent failure. At the same time application of information technology in organizations faces various potential risks. Exploring information technology environment in organizations reveals the potential risks and provides a structure for comprehensive risk management. There are various methods available for risk mana...

Recent advances in technology have created a modern computational environment in which high performance commodity superclusters are interconnected by high bandwidth Internet connections, thus establishing a worldwide computational grid with large aggregate computational capabilities. Several projects attempt to build on this infrastructure by providing mechanisms that allow grid resources to be...

Limited research has focused on recruitment strategies for health promotion researchers conducting small-scale pilot studies. Such research is important because small studies often have limited funding streams and personnel resources. Accordingly, many techniques implemented by large-scale studies are of limited use to smaller research projects. This article provides an overview effective parti...
