Vapour Compression

The elastocaloric cooling, utilizing latent heat associated with martensitic transformation in shape-memory alloys, is being considered in the recent years as one of the most promising alternatives to vapour compression cooling technology. It can be more efficient and completely harmless to the environment and people. In the first part of this work, the basics of the elastocaloric effect (eCE) and the state-of-the-art in the field of elastocaloric materials and devices are presented. In the second part, we are addressing crucial challenges in designing active elastocaloric regenerators, which are currently showing the largest potential for utilization of eCE in practical devices. Another key component of elastocaloric technology is a driver mechanism that needs to provide loading for active elastocaloric regenerators in an efficient way and recover the released energy during their unloading. Different driver mechanisms are reviewed and the work recovery potential is discussed in the third part of this work.

The Third World

Abstract:The state of the art is summarized showing many efforts but only few results which can serve as demonstration examples for developing countries. Education in health informatics in developing countries is still mainly dealing with the type of health informatics known from the industrialized world. Educational tools or curricula geared to the matter of development are rarely to be found. Some WHO activities suggest that it is time for a collaboration network to derive tools and curricula within the next decade.

Abstract. This paper introduces the Atmospheric Measurement Techniques special issue on tropospheric profiling, which was conceived to host full papers presenting the results shown at the 9th International Symposium on Tropospheric Profiling (ISTP9). ISTP9 was held in L'Aquila (Italy) from 3 to 7 September 2012, bringing together 150 scientists representing of 28 countries and 3 continents. The tropospheric profiling special issue collects the highlights of ISTP9, reporting recent advances and future challenges in research and technology development.

The Impact

The chapter provides an overview of how policy analysis takes place in Mexican Think Tanks. It focuses on two of the few organisations of this kind that currently exist in the country: the Centro de Investigación para el Desarrollo (CIDAC, or Centre for Research for Development) and the Centro de Estudios Espinosa Yglesias (CEEY, or Centre of Studies Espinosa Yglesias). The chapter is divided into four sections. The first discusses the main features of think tanks, with a particular focus on the Mexican ones. The second presents the origins and general objectives of CIDAC and CEEY, and describes how these two organizations conduct policy analysis. The third compares both cases, paying particular attention to how they define their topics of interest, how they gather relevant information, what kind of policy products they generate, what kind of communication channels they use, and how they assess the impact that their analyses may have had. The chapter closes with some conclusions and general remarks about the future challenges of policy analysis in Mexican think tanks.

Towards a Model of Learner Variation in Autonomous Foreign Language Learning

Language Needs

My intent in this short piece is to provide a context for consideration of learner variables in foreign language learning. I first propose a question set outlining the major issues, as I see them, arising in the design of learner-based foreign language learning systems. I then present a simplified three-part design model comprising knowledge considerations (language needs assessment), instructional considerations (learning access alternatives) and learner considerations (characteristics of learners). A review of some recent work in the first two of these prefaces the discussion of the third, learner considerations. A brief state of the art report on research in learner variables is followed by some speculation on next directions in the determination and description of learner variables within a general design model for learning foreign languages.
