[null,null,null,"Sommario/riassunto","The transferability of vocational education and training qualifications across international borders is a live issue in this heterogeneous field. Key to this goal is defining a common methodology for measuring vocational competences. This publication sets out a proposal for just that, based on the results of a pilot project known as ‘COMET’ on competence diagnostics in the field of electrical engineering. The study deploys longitudinal analysis to explore issues of competence "]

It focuses on two discrete occupational profiles in electrical engineering in an ambitious test of a model currently applied to other professions as well. The model’s success in its first phase is detailed in the second part of the volume, where the authors show that the transfer of the competence framework into an empirical model was successful. They also demonstrate that the methodology can be applied to designing and evaluating vocational education and training processes, making the material relevant to VET teachers and trainers as well as academics. With its first section comprising a full description of the theoretical framework, this book is a significant step forward in an urgent task facing administrations, labor forces and employers around the world. The achievement is in proportion to the notorious complexities of a field whose diversity makes tough demands on large-scale methods of assessment."]

[null,null,null,"Sommario/riassunto","This book presents the ideas and industrial concepts in compact heat exchanger technology that have been developed in the last 10 years or so. Historically, the development and application of compact heat exchangers and their surfaces has taken place in a piecemeal fashion in a number of rather unrelated areas, principally those of the automotive and prime mover, aerospace, cryogenic and refrigeration sectors. Much detailed technology, familiar in one sector, progressed only slowly over the boundary into another sector. This compartmentalisation was a feature both of the user industries themse"]
