An Analysis of the Impact of the Internet on Coastal Management

The role of the Internet in coastal management practice is analyzed through the Internet's communication and information access capacity. Primary and secondary impacts of the Internet in coastal management are assessed. A broad research framework is employed, including background on the development and spread of the Internet worldwide; analysis of emerging literature on the societal impact of the Internet; limited existing research on the use of the Internet by environmental management professionals generally and coastal managers in particular; and personal experience of the authors in the development of coastal management Internet sites. This analytical framework is supplemented by the first survey of integrated coastal management (ICM) Internet websites by www.coastalmanagement.com and a case study of the Internet Center for Coastal Management (ICCM) Internet-based communication platform based at the University of Washington. The survey of ICM websites found a total of 77 websites worldwide, with a dominance of sites in English located in the developed world. Assessment of the first year of operation of the ICCM project to facilitate discussion between coastal management practitioners and students in the United States and the Philippines demonstrates the enormous potential of the Internet as a communications tool in coastal management and also reveals the many practical technological and cultural constraints of using the Internet, especially in working on a project between the developed and developing world. Three groups of scenarios of the future use of the Internet in coastal management with decreasing levels of forecast certainty, namely, "probable," and "possible," and "potential for" are presented and discussed. Finally, the potential for the Internet to fundamentally transform the practice of coastal management is analyzed. It is concluded that while such a potential exists, there remain significant research questions requiring further analysis before the full transformative potential, and the possible impacts of such a transformation on coastal management, can be fully assessed. This article aims to provide a benchmark against which such future assessments can be made.     

中职学生知识与技能的“专”与“广”及教学策略

中职教育对学生培养中知识和能力的"专"与"广"是对立统一的。"专"具有引领作用,是核心。"广"是基于"专"的拓展弥补和充实"专"的不足。它们在某种情况下又相互转化,主导它们之间的关系和地位的,是中职教育的就业导向。因此,必须从就业需要出发,处理好二者的关系。
