It was an interdisciplinary approach of ecological and cultural views of biodiversity. Special educational material was prepared with photos and texts of archaeological excavations and field sampling which was used in real and virtual environment, in t~ discovery teaching of Natural Sciences and History subjects. Students, in a scientific research project with constructive teachings, followed the procedures by which scientists gather, analyze, synthesize, process and evaluate information of organisms of Crete since 4000 years. Crete is located between the natural limits of three continents, having the unique privilege to host permanently or in migration, distinctive species of these three continents. After having the research questions, teachers collected the educational material, organized the work groups, implemented the didactic intervention in the classroom, had the field sampling of plants, recognized the synchronous local and scientific names of the plants, constructed the botany book, photographed the collected organisms and all the concentrated material was delivered to the team members.展开更多

These studies involve unique difficulties, especially in the calibration of hydro-models because there is no direct way to continuously measure the SIM at hydrostations. The recursive digital filter （RDF） and the isotopic hydro-geochemical method （IHM） were coupled to separate the SIM from eight observed series of alpine streamflows in northwestern China. Validation of the calibrated methods suggested a good capture of the SIM characteristics with fair accuracy in both space and time. Applications of the coupled methods in the upper reaches of the Hei River Basin （HRB） suggested a double peak curve of the SIM fraction to streamflow for the multi-component recharged （MCR） rivers, while a single peak curve was suggested for the rainfall-dominant recharged （RDR） rivers. Given inter-annual statistics of the separation, both types of the alpine rivers have experienced an obvious decrease of SIM since 196os. In the past 10 years, the SIM in the two types of rivers has risen to the levels of the 1970s, but has remained lower than the level of the 1960s. The study provided a considerable evidence to quantify the alpine SIMbased on the separation of observed data series at gauge stations. Application of the coupled method could be helpful in the calibration and validation of SIM-related hydro-models in alpine regions.展开更多

Campus sports culture is a combination of basic social culture and sports culture in the campus group products, with cultural characteristics. System science is to provide the comprehensive approach for us, whether it is system engineering or operations research, whether the system analysis and network planning, the system provides the scientific research methods are first in the whole system of standing height above, students through the independent thinking, listening carefully, hands-on operation, active speech and other explicit behavior, and while constantly internalized teaching content and enrich their knowledge structure. Under this basis, this paper proposes the new idea of the teaching model of the physical education in colleges based on interactive teaching method and participatory teaching. The effect will be evaluated in the future research.展开更多

It is a theoretical and empirical approach, whose developments have been used by the Communication and Work Research Group of Communications and Arts School--University of SAo Paulo, Brazil. The reception from the world of work shows how changes in the labor act concretely in daily life subjectively and how they manifest in the sphere of cultural consumption. The research shows how, from the reception, the journalists reveal from which place they talk about the world, the society, and their own work. The reception is revealed as the moment par excellence ＂to talk about work＂. When talking about the other＇s work, the journalists are confronted with their own work and reveal, in their discourse, values and dramas of real activity of communication and work.展开更多
