A deductive model of the energy budgets of urban landscapes, based on the exchanges of energy, mass, and momentum, is introduced. The absorption of shortwave and longwave radiation and their dissipation via the channels of reradiation, convection, conduction, and evaporation are generated by the model in order to simulate the interplay of the many energy cascades among the myriad of city surfaces. A city can be geographically analyzed by determining its energy budget and resultant surface temperatures on a block-by-block basis. In spite of some simplifying assumptions, the predictions of surface temperatures of this initial model compare favorably with observations. 相似文献

Since it's early days modern science is confronted with the following dilemma: Scientific investigation of nature requires the availability of the scientist's body in nearly all of its activities, though on the other hand science feels obliged to minimalize any influence of this body for methodological reasons. How has science dealt with this dilemma? How has it managed to keep the balance between using the body in favour of knowledge and keeping the required distance to it? In answering these questions the paper tries to reconstruct the history of early modern science from an anthropological perspective. 相似文献

Systems thinking is regarded as a key competence in the field of education for sustainable development (ESD), because it helps students to understand the complexity and dynamics of natural, social and economic systems. In our research group, we developed a competence model that distinguishes four dimensions of systems thinking in ESD. Based on this model, we designed different university courses in biology and geography teacher education and measured their effects on student teachers’ systems thinking and the pedagogical content knowledge for teaching systems thinking with two different tests. Both variables could be effectively promoted depending on the course. 相似文献

AbstractThis paper presents an analysis of a research project conducted by a network of environmental research institutes called Partnership for European Environmental Research (PEER). Our analysis constitutes a reflection on this research project based on a proposed ideal-typical transdisciplinary research process developed by . The aim of the PRESS project (PEER Research on EcoSystem Services) was to provide support for the development and implementation of the EU Biodiversity Strategy to 2020, with a special emphasis on the ecosystem services concept. Our analysis of the research phases of the PRESS project shows that not all of the project elements accord with the notion of a full-scale transdisciplinary process. Despite this, a number of lessons can be learned regarding the use of different boundary objects for knowledge integration and the various roles played by researchers. We also identify some constraints with regard to synchronizing policy and project cycles and consider the advantages and disadvantages of research network structures in facilitating long-term cooperation. 相似文献
