印度暴力袭击事件的时空演变及其驱动机制

基于全球恐怖主义数据库（GTD）和南亚恐怖主义门户网站（SATP）所收录的印度暴力袭击事件数据,借助统计分析和核密度分析法,对1980—2017年印度暴力袭击事件时空演变及其驱动机制进行分析。结果表明：印度国内的暴力袭击事件频发,1980年以来呈现出波动上升态势。从空间上看,印度国内的暴力袭击事件具有自西到东、从北到南以及由边境地区向内地发展的扩散特点,展现出局部集中、面上扩散的发展趋势;呈现出以西北部的查馍-克什米尔地区和旁遮普邦、东北部的阿萨姆邦和曼尼普尔邦、中部的恰蒂斯格尔邦和东部的贾坎德邦、比哈尔邦和西孟加拉邦为主的四大集聚中心;形成以印度河上游—恒河—布拉马普特拉河一线为横轴,东高止山脉及其北部山区为纵轴的“T”字形空间格局。印度暴力袭击事件的时空演变受到身份认同、经济问题、历史问题和利益诉求等多方面因素的影响,通过宗教极端主义组织、民族分离主义组织、武装革命主义组织推动以及行动主体之间的互相作用,推动了暴力袭击事件的时空演变。要从根本上解决印度国内暴力袭击事件频发的态势,需要从政治、经济、宗教、社会等多方面进行综合施策。

From national to post-national territorial identities in Israel-Palestine

Territory remains a central component of national identity in the contemporary political discourse between Israelis and Palestinians, both populations opposing power sharing within the same space, for fear of the other's domination. The contemporary political discourse relates to conflict management and the desire for separate spaces within which national identities are strengthened through territorial/national homogeneity. The Zionist national ideology of most Jewish citizens of Israel has strong territorial roots; hence they reject the post-Zionist post-nationalist ideology, regardless of whether they accept the possibility of change in Israel's territorial configuration or of a diminishment in the importance of the territorial dimension of national struggle. The rights of residency and citizenship even of second and third generation Jewish citizens remain linked with the territorial configurations of a State that will continue to be called Israel and have a national anthem expressing the aspirations of a single, exclusive, national group. But within territorial readjustment, issues of configuration may become less relevant and in it is this sense that post-Zionism focuses on a discourse of territorial pragmatism, rather than the disappearance of territory from the nationality-citizenship debate altogether. It is part of a process of re-territorialization and spatial reconfiguration of political and national identities, not a reversal of territorialization, if only because there is no such thing as a post-territorial notion of the organization of political power. The boundaries of national identity become more permeable, more inclusive, but they do not disappear altogether.     

Ecological conflicts in Poland

Transformation of the political system, observed in Poland for 10 years in connection with economic restructuring and basic socio-economic reforms to harmonise with European Union structures, is also evident in terms of environmental management. Pollution has been reduced in many ways but the rise in living standards, linked with the rapid growth of cars and other forms of consumption, has had a negative effect and environmental conditions have deteriorated in the central areas of large cities. The growth of waste water and refuse is a considerable problem. More areas are now officially protected and the three levels of local government established at the beginning of January 1999 (voivodeship, district and community) all have certain defined environmental protection responsibilities which are cumulatively greater than before. Meanwhile there is a greater awareness in society of environmental issues, although it does not yet lead to a high level of participation in protection work. However, there are strongly-expressed opinions on the ecological acceptability of certain economic developments and conflicts are frequently arising within communities and local governments and also between investors on the one side and ecological organisations and environmental protection institutions on the other. Most controversial are new roads, power stations (like the Zarnowiec nuclear project) and reservoirs like the one on the Dunajec river at Czorsztyn. Local communities frequently resist plans for waste dumps, incinerating plants and other developments which are seen as injurious to health or the quality of life. The planned reprivatisation of the state-owned forests is also criticised by foresters and ecological movements. Conflicts are likely to grow as economic development accelerates but better information and greater public understanding of the need for sustainability should make for consensus.

National territorial planning at the turn of the 21st century

In the early stages of economic development in Korea, national territorial planning was used as a policy tool to guide spatial structure and to provide physical infrastructure for urban and industrial development. Such a top-down approach was inevitable because Korea maintained the centralized political and government system until the early 1990s. Circumstances, however, have changed recently since the 1990s with progress in democratization and localization. In addition, forces of globalization are making significant impacts on the parameters of national territorial planning. Reflecting these changes in both internal and external conditions, the Fourth National Territorial Plan (2000–2020) has adopted a different approach from the past three territorial plans. This paper reviews the socio-economic background that necessitated such changes in approaches to national territorial planning. A major thrust of the Fourth Plan, a focus on emergent or anticipated planning issues in Korea, is discussed. Finally, the paper examines the rationale for long-term strategic planning in the highly fluctuating situation facing Korean society in the new century.

An experiment on reservoir representation schemes to improve hydrologic prediction: coupling the national water model with the HEC-ResSim

ABSTRACT

This study experiments with reservoir representation schemes to improve the ability to model active water management in the National Water Model (NWM). For this purpose, we developed an integrated water management model, NWM-ResSim, by coupling the NWM with HEC-ResSim, and two reservoir representation schemes are tested: simulation of reservoir operations and retrieval of scheduled operations. The experiments focus on a pilot reservoir domain in the Russian River basin – Lake Mendocino, California – and its contributing watershed. The evaluation results suggest that the NWM-ResSim improves the simulation performance of reservoir outflow from this managed reservoir over the NWM default level pool routing scheme. The degree of this improvement depends on the suitability of the operation guidance; the reservoir operations simulation scheme could have acceptable errors for the purposes of water resources management, but not for flood operations. Results of the retrieval scheme of scheduled operations demonstrated better performance for sub-daily flood operations.
