Abstract

This study investigated the effects of using a long-duration, project-based science professional development model on the acquisition of declarative knowledge and basic terminology associated with the use of geographic information technologies (GIT), teachers' self-assessed confidence in using GIT skills, and the implementation of GIT in participants' classrooms. Results suggest that a long-duration, project-based science model was effective in teaching GIT declarative knowledge and raising teachers' self-confidence in using GIT tools. The academy was funded through a grant from the US Department of Education with additional support from Environmental Science Resources Institute (ESRI), Inc., and members of the New Mexico Geographic Information Council.  相似文献

This article examines the science–policy interface in volcanic risk assessment. It analyses empirical data from research on Montserrat, where new volcanic risk assessment methodologies were pioneered. We discuss the ways in which these methods contributed towards the ordering of scientific advice in its geographical context, and we provide examples of the complex and overlapping topologies that are assembled in a volcanic eruption. In this case, the science–policy interface can be conceptualised as diffusive: both science and policy contain multiple overlapping networks of actors, objects and ideas that interact with one another through flows of responsibilities, attribution, identity and interpretation. Volcanic risk management involves negotiation of conceptual, relational and physical boundaries, and as a result requires the use of qualitative and quantitative methods across human and physical geography.  相似文献

The taxonomic status of previously misplaced species of an ant-like stone beetle from Spanish amber (Albian) is clarified. Specimens of Kachinus magnificus (originally placed as incertae sedis within Scydmaenitae) were re-examined and their characters were found different from those of the type species of Kachinus from Myanmar amber. Consequently, Archeutheia gen. nov. is proposed to accommodate the Spanish species, resulting in Archeutheia magnifica comb. nov. Moreover, in a comprehensive phylogenetic analysis Archeutheia was placed as a sister group to extant Eutheia, within the tribe Eutheiini of Cephenniitae. A specimen of an undetermined genus from Myanmar amber clearly belonging in Cephenniini is also recorded. Both taxa represent the first definite Cretaceous Cephenniitae, a supertribe whose recent members are distributed on all continents but are especially diverse in the Oriental and East Palaearctic regions. This finding demonstrates a diversification of two presently most species-rich tribes of Cephenniitae already in Early Cretaceous. Archeutheia is strikingly similar to the extant species of Eutheia and Veraphis, showing male dimorphic characters (modified protrochanters) and antennal cavities characteristic of Palaearctic Eutheiini. This fact suggests a long morphological stability in the supertribe. A previously proposed hypothesis of an early presence of the Cephenniitae in the Northern Hemisphere is for the first time supported by the fossil record, and the palaeolocalities (western Europe and Southeast Asia) demonstrate a wide distribution of Cephenniitae in the Cretaceous and an early split of its ancestral lineage.  相似文献

During several decades of investigation, the East Pacific Rise seafloor-spreading center at 9°-10°N has been explored by marine geologists, geophysicists, chemists, and biologists, and has emerged as one of the best studied sections of the global midocean ridge. It is an example of a region for which there is now a great wealth of observational data, results, and data-driven theoretical studies. However, these have yet to be fully utilized, either by research scientists or educators. While the situation is improving, a large amount of data, results, and related theoretical models still exist either in an inert, noninteractive form (e.g., journal publications) or as unlinked and currently incompatible computer data or algorithms. Presented here is the prototype of a computational environment and toolset, called the Virtual Research Vessel, to improve the situation by providing marine scientists and educators with simultaneous access to data, maps, and numerical models. While infrastructure is desired and needed for ready access to data and the resulting maps via web GIS in order to link disparate data sets (data to data), it is argued that data must also be linked to models for better exploration of new relations between observables, refinement of numerical simulations, and the quantitative evaluation of scientific hypotheses. For widespread data access, web GIS is therefore only a preliminary step rather than a final solution, and the ongoing implementation of the Virtual Research Vessel (scheduled for final completion in 2004-2005) is a case study for the midocean ridge community to test the effectiveness of moving beyond the data-to-data mode towards data-to-models and data-to-interpretation.  相似文献

流域科学与水资源管理   总被引:1,自引:0,他引:1  
流域是水资源管理的基本单位。基于水资源文献的综合分析,讨论了自20世纪以来水资源管理概念、目标及途径的变迁,提出建立流域科学,以流域为研究对象,以揭示流域生态水文过程的客观规律为前提,采用现代管理科学理论和方法,应用先进工程技术手段优化配置水资源,满足人类活动及生态系统的多种需求,促进社会、经济及环境的可持续发展。并且指出流域科学的内涵应包括:①水资源的调查、监测和模拟;②水资源利用多目标设定;③水资源分配机制;④水资源管理指标的确定与评价;⑤水资源管理决策机构;⑥水资源管理反馈分析与人类活动调控。  相似文献

To settle the difficulties of the shortage of oceanographic research vessels in our country, the National Natural Science Foundation Committee of China founded Oceanographic Research Vessel Sharing Plan in 2009. It is aimed at enhancing efficiency and optimization of the vessel resources,and coordinating the use demands of vessels for the different foundation projects and the efficient use of the research vessels. We have summarized the achievements made in the Plan from 2010 to 2014, as well as the use system of the research vessels sharing, the specific operating mode ,the organization and the management framework of the Plan. In the end, we put forward our suggestions on the improvement of the Plan after the primary analysis of the present situation of the sharing of the survey data and the existing problems.  相似文献
