Driving Sustainable Innovation: A Pioneer for the 21st Century

An interesting look into one of the premier automobile manufacturers and the design team behind its emergence as a force – not only in the development of new and more efficient vehicles – but in the application of these eco-centered guidelines to other consumer products as well. Verena Kloos provides a rare insight into the role of not just a female officer in an industry largely dominated by men, but of a leader committed to embracing change where demanded

El futuro de la tecnología educativa

Aprendizaje es cambio, y, de forma natural, el campo de la educación siempre ha estado abierto a innovaciones tecnológicas. El campo interdisciplinar emergente del "technology-enhanced learning" o TEL (que podríamos traducir como "aprendizaje potenciado por la tecnología") se puede decir que hoy en día avanza a gran velocidad. Especialmente en los últimos años, en los que ha habido un apoyo significativo de financiación de la Unión Europea, de grandes iniciativas nacionales y de la dedicación entusiasta de organizaciones e individuos, se han logrado avances considerables

Authoring courses with rich adaptive sequencing for IMS learning design

This paper describes the process of translating an adaptive sequencing strategy designed using Sequencing Graphs to the semantics of IMS Learning Design. The relevance of this contribution is twofold. First, it combines the expressive power and flexibility of Sequencing Graphs, and the interoperability capabilities of IMS. Second, it shows some important limitations of IMS specifications (focusing on Learning Design) for the sequencing of learning activities

Improving water use efficiency under worsening scarcity: Evidence from the Middle Olifants sub-basin in South Africa

With the political changes in South Africa in the early 1990s, the South African government introduced a reform process in the entire water sector with the goal of a more enhanced and equitable water management system. This paper analyzes existing water allocation situations and applies a nonlinear optimization model to investigate the optimal intra- and inter-regional allocations in the Middle Olifants sub-basin of South Africa. Results show higher benefit from inter-regional water allocation. Reducing water supply levels to conform to the sustainable water supply policy, it can be shown that although water supply is reduced by approximately 50%, total benefits from water are only reduced by 5% and 11% for inter- and intra-regional allocation regimes respectively. These results indicate that alternative water allocation mechanisms can serve as instruments to offset for the effects of water scarcity.Water allocation, IWRM, Olifants basin, South Africa, Africa, Resource /Energy Economics and Policy,

A simple, ultrahigh vacuum compatible scanning tunneling microscope for use at variable temperatures

We present the construction of a very compact scanning tunneling microscope (STM) which can be operated at temperatures between 4 and 350 K. The tip and a tiny tip holder are the only movable parts, whereas the sample and the piezoscanner are rigidly attached to the body of the STM. This leads to an excellent mechanical stability. The coarse approach system relies on the slip-stick principle and is operated by the same piezotube which is used for scanning. As an example of the performance of the device, images of a NbSe2 surface with atomic resolution are obtained

MEDICAL GEOGRAPHY : ITS ROLE IN DISEASE CONTROL AND HEALTH DEVELOPMENT IN AFRICA WITH PARTICULAR REFERENCE TO ETHIOPIA

ABSTRACTThis paper attempts to review selected medical geographical studies with objective of providing an overview of the sub field to geography and suggesting possible areas of collaboration with epidemiologists and public health officials in disease control programmes in Africa, particularly Ethiopia. A combination of: (1) complimentarity between medical geography and epidemiology; (2) the appropriateness of geography in analysing man-environment interactions; (3) the broad range of topics in disease ecology and health care delivery and utilization covered by medical geographers; (4) the need to evaluate aspects of the physical and socioeconomic environment in socialist Ethiopia for planning purposes and; (5) existence of viable programmes in medical geography in other African countries warrant consideration of this applied discipline in collaborative and interdisciplinary disease control programmes in Ethiopia
