This research aims to create a methodology for the integration of leadership development in teaching Information Technology (IT) courses by using the Problem Based Learning method (PBL). The research objective was pursued through a review of important current and future leadership skills that IT students need to develop in order to meet IT job market challenges. A conceptual leadership model was developed. This research then investigated the alignment of this conceptual model with the skills requirements of the IT job market and the impact of employing the PBL approach. This study used a quantitative method of survey that was completed by undergraduate students enrolled in an IT web development course. Findings indicated that the use of PBL is an integral part of the process of daily leadership development in teaching IT courses. Students’ perceptions were studied and positive views were recorded.

This paper discusses the concepts and operations related to the specification and management of a community of Web services, respectively. Web services offering the same functionality are gathered into one community, independently of their origins. The community is led by a master component, which is responsible among others for attracting new Web services to the community, retaining existing Web services in the community, and identifying the Web services in the community that will participate in composite Web services. The identification of these Web services is based on the contract-net protocol. 1 Similar Web services and Web services with a similar functionality are interchangeably used.
