This article discusses recent standardization efforts related to cognitive radio focusing on the work of IEEE Standards Coordinating Committee 41, formerly known as IEEE 1900. Some important tasks to be performed by the CR standardization community also are presented. These tasks will expedite the introduction of CR devices to the market while promoting a fair use of scarce radio resources. Some avenues for using the currently available standards for rapid deployment of CR devices, such as ISO standards, also are discussed.

The rapid expansion in users of mobile devices, particularly among university students, makes mobile learning (m-learning) the modern style of learning for the new millennium. Thus, it is important to identify and explore the factors that may influence students' intention to use m-learning. In Jordan, research on mobile learning adoption is still very narrow. For the purpose of this study, we propose a framework that is based on the unified theory of acceptance and use of technology (UTAUT) model, to explore the potential factors that may impact students' intention to acceptance and use of m-learning in developing countries such as Jordan. The proposed framework is empirically tested using a total of 444 paper-based questionnaires, collected from students at four Jordanian universities. The results reveal that effort expectancy, performance expectancy, trust expectancy, self-management of learning, system functionality and social influence are significant determinants of m-learning adoption, and explain 64.8% of the variance in the students' intentions to adopt m-learning. Gender and uncertainty avoidance are found to have moderating effects on some of the relationships of the research model. These findings offer multiple useful implications for m-learning adoption, in terms of both research and practice.

This paper describes an investigation into the utility of an agile development approach known as rapid application development (RAD) within a largescale development project conducted within the public sector in the UK. Features of RAD as an 'agile' information systems development method (ISDM) are discussed and previous research identifying properties of development environments most conducive to its application are described. A case study is then presented based upon a long-term qualitative investigation of the 'unbundling' of a commercial RAD-like ISDM. The evidence from this case leads us to question established wisdom in relation to appropriate adoption and application of agile developmentwithin large-scale and complex development environments.i sj_329 549..570
