The primary goal of this research is to design and develop an education technology to support learning in global operations management. The research implements a series of studies to determine the right balance among user requirements, learning methods and applied technologies, on a view of student-centred learning. This research is multidisciplinary by nature, involving topics from various disciplines such as global operations management, curriculum and contemporary learning theory, and computer aided learning. Innovative learning models that emphasise on technological implementation are employed and discussed throughout this research.

The paper extends the current literature on peer review journal evaluations by providing a number of insights based on the diversity of Production and Operations Management (POM) research. We provide peer review evaluations for POM research outlets, based on a sampling frame that includes a large number of POM researchers worldwide. More specifically, the paper develops and tests various hypotheses as to whether the perceived quality and relevance of a journal is affected by such factors as: (i) nature of research work (empiricists versus modelers), (ii) society membership, (iii) research productivity, (iv) geographical location, and (v) seniority. Our findings suggest that caution must be exercised when utilizing existing POM journal rankings, as some factors, particularly the difference between empiricists and modelers, may influence journal evaluation. These must be considered when addressing issues such as faculty promotions, tenure, and salary. © 2006 Elsevier B.V. All rights reserved.

This study of concentrating solar thermal power generation sets out to evaluate the main existing collection technologies using the framework of the Analytical Hierarchy Process (AHP). It encompasses parabolic troughs, heliostat fields, linear Fresnel reflectors, parabolic dishes, compound parabolic concentrators and linear Fresnel lenses. These technologies are compared based on technical, economic and environmental criteria. Within these three categories, numerous sub-criteria are identified; similarly sub-alternatives are considered for each technology. A literature review, thermodynamic calculations and an expert workshop have been used to arrive at quantitative and qualitative assessments. The methodology is applied principally to a case study in Gujarat in north-west India, though case studies based on the Sahara Desert, Southern Spain and California are included for comparison. A sensitivity analysis is carried out for Gujarat. The study concludes that the linear Fresnel lens with a secondary compound parabolic collector, or the parabolic dish reflector, is the preferred technology for north-west India.
