To integrate lessons from the U.S. Department of Agriculture (USDA), National Institute of Food and Agriculture–Conservation Effects Assessment Project (NIFA CEAP) program, key informant (KI) interviews were conducted in all 13 project areas. The purpose of these interviews was to supplement technical information about watersheds, their contaminants, modeling, economics, and key findings. We interviewed a wide range of people to develop a systematic look at individual project results, synthesize meanings, and derive principles useful in guiding future watershed management. Findings revealed common themes, which tended to align with KI categories, regardless of location. For instance, farmers and ranchers often understood water quality problems as well as federal and state personnel and university employees do. Conservation adoption by farmers was related to perceived need, cost, and convenience of the practice, as well as practice specifics and individual situations. Possible implications of these findings are advanced. 相似文献

Although continued knowledge acquisition is necessary, there is an increasing need for innovative manipulation. Consequently, the roles of sound science and considered educational practice need clarification within coastal policy. Research data, collected via semi-structured interviews with representatives of government and quasi government organisations encompassing various Mediterranean and Black Sea countries, was subsequently assessed alongside published work. Principal findings emphasised that policy makers need to engage more coherently with the existing science education nexus to facilitate, but not format research agendas. Although extensive information is readily available, there is need for further manipulation, translation, coordination, communication and adaptation between policy portfolios. Consequently, the science education nexus should be internalised into policy formulation, implementation and monitoring. Furthermore, to develop shared awareness, considered dissemination of knowledge and understanding requires both vertical and horizontal integration. Policy results should be clear and innovative knowledge transfer fora, using Technology Enhanced Dissemination (TED) within culturally sensitive contexts, must be developed. Science and education require legal incorporation from which professional norms and authority can evolve. Findings suggested that although the science is ‘hard’, incorporating it into policy decisions is ‘harder’ and hence, more effort is needed. 相似文献

“数字地球”是一个可以嵌入海量地理数据的、多分辨率的、真实地球的三维表示。自美国前副总统戈尔提出“数字地球”概念以来 ,世界上许多国家都在探讨如何实施本国的“数字地球”战略 ,力争在当今科技制高点上占据一席之地。在实施“数字地球”战略时 ,作为地球表面人口、资源、环境、信息最密集的地区 ,城市必然成为主要切入点之一。“数字城市”研究是当前地理信息科学研究的一个热点。与“数字地球”不同 ,“数字城市”是在城市数字化基础上建立的一个能够实现城市综合管理与决策支持的、虚拟的、具有开放性的城市模型。 相似文献

This paper examines social and spatial inequalities in personal usage of information technologies, drawing on data made available recently as part of Australia's national census, undertaken by the Bureau of Statistics in 2001. Data on both computer and Internet use are analysed in a number of ways: patterns of use and non-use of the technology are examined across New South Wales in relation to a number of variables, including age, place of birth, indigeneity, income and educational status. Selected results are mapped for State-wide trends and within Sydney, revealing spatial inequalities both across and among regions. Correlation and regression analysis are used to demonstrate the strength of association between computer and Internet use and other socio-economic variables. The results suggest that there is a strong class as well as spatial dimension to Australia's digital divides. Educational status and income mediate use of computers and Internet technologies, in addition to factors associated with location, indigeneity and birthplace. Such observations reinforce those made elsewhere regarding the uneven geometries of power apparent in information economies, and suggest interventions in public policy debates, particularly in the areas of telecommunications provision, resourcing of public schools, and regional economic development. 相似文献
