Abstract: Jharkhand is at the centre of India's struggles to define ‘the environment’ and ‘economically relevant natural resources’. Although cultural labels are applied by leaders who seek influence in these struggles as well as by many of those people who listen, an ethnonational analytic frame does not help answer the questions: How, why and when has the political idea of environment changed in India? When and why has the Jharkhand movement chosen violent tactics? When and why has the Jharkhand statehood movement realised electoral success? Or, why was Jharkhand state formed? To address such questions, a long range historical‐institutional approach is much more fruitful. 相似文献

Abstract: West Kalimantan (West Borneo) has a history of violent communal conflict.1 It also has extensive forests that have been looted for decades. The argument will be that these two are linked, but not by the grievances of the forest dwellers. Except in its first few days, the two main episodes of 1997 and 1999 were not driven mainly by grievances among marginal groups. Rather, explanations based on the ‘resource curse’ carry more weight. These focus attention on the contested nature of the state, rather than on rebellious activities of marginal groups. When state institutions were thrown into disarray by the sudden resignation of President Suharto in 1998, Dayak militants already close to state power rewrote the rules of local politics by demonstratively ‘cleansing’ certain areas of an unpopular immigrant minority. This theatrical manoeuvre impressed political rivals sufficiently to allow Dayaks to gain control over several timber‐rich districts, which had a thriving black economy. Malays later imitated these techniques to stem the tide. 相似文献

不同蔬菜对重金属汞、铬、砷、镉、铅积累效应的研究 总被引：3，自引：1，他引：2
为了对辽宁省葫芦岛龙岗区蔬菜生产基地蔬菜生产结构的调整提供科学的参考,采用原子吸收的方法,对该生产基地的土壤与蔬菜中重金属(Hg、Cr、As、Cd、Pb)的含量进行检测。结果表明：该蔬菜基地土壤中Hg的含量平均为0.42 mg/kg,Cr的含量平均为52.20 mg/kg,As的含量平均为34.92 mg/kg,Cd的平均含量为0.93 mg/kg,Pb的含量平均为98.49 mg/kg,说明该地区的土壤中重金属含量基本符合农业生产的要求;该蔬菜基地蔬菜中Hg的含量平均为0.92 μg/kg,Cr的含量平均为120.09 μg/kg,As的含量平均为13.80 μg/kg,Pb的含量平均为94.17 μg/kg,Cd的平均含量为15.65 μg/kg,并且所测定的蔬菜样本中甘蓝在5种重金属的含量上均比其他蔬菜的含量高,但也能符合国家卫生标准。此实验可为该蔬菜区蔬菜生产结构的调整提供一定的参考。 相似文献

ABSTRACT Today rapidly growing economies depend more on the creation, acquisition, distribution, and use of knowledge. As such, strategies for enhancing research and innovation capabilities have come to occupy a more important position in many developing nations, including China. Already the leading production center, and often seen as China's economic locomotive, Shanghai is striving aggressively to retain its national preeminence and has launched concerted efforts to increase local innovative output. The primary purpose of this paper is to understand how state‐led efforts have fared in promoting technology innovation. By situating the city in the national and global context, the paper shows that Shanghai has gained a substantial lead in developing an innovation environment with extensive global linkages and leading research institutions. Recent efforts in building up the research and innovation capacity of the enterprise sector have begun to show progress. Although firms are enthusiastic about its future as an innovation center, Shanghai continues to face challenges of inadequate protection of intellectual property, lack of venture capital investment, and the tightening supply of highly qualified knowledge workers. 相似文献

Abstract: Many in Thailand have begun to worry about the future, when a new monarch will reign. There is fear that without the wise use of informal royal influence, Thailand may not be able to resolve future crises without major conflict. There have thus been attempts to re‐engineer the political system to increase stability, at the expense of democracy and participation. Yet, of the many achievements of King Bhumibol, perhaps the most overlooked has been his strengthening of the institutions of the monarchy. In this article, I will argue that the institutions of the monarchy have been greatly strengthened in the last four decades. Although the current monarch came to the throne with little institutional support, any future monarch will come to the throne with the assistance of large numbers of personnel, a stable budget and a council of powerful and experienced advisors. The informal role of the monarch in supporting democracy has also been shared, to some degree, with a larger and more influential privy council, and especially with its president. Consequently, future monarchical succession should see considerable continuity and stability. Such preparations make the sacrifice of democracy in pursuit of stability unnecessary and unfortunate. 相似文献

Abstract: This paper considers the convergence of immigration/globalisation and education in New Zealand. The issues of immigrant students at Epsom Normal Primary School were raised nationally in 1995, and this incident serves as a useful departure point to consider some of the challenges involved in bridging the gap between immigration and education. Educational immigration is a notion used by Belich (2001) amongst others, to suggest that immigrants arrive in New Zealand in order to bypass full cost fees paid by international students. This notion, while useful, is challenged. Research undertaken in North Shore City as well as official immigration figures show the complexities of the issue: immigrant communities may be indirect recruiters of these students, but there are also an increasing number of international students becoming permanent residents. Either way, education providers face particular challenges with migrant students, not only in terms of English language abilities, but also in the lack of financial incentive migrant students give to an education provider relative to international students’ contributions. These micro issues are placed in perspective when returning to considering the transient nature of many young migrants exploring opportunities in a globalised world. 相似文献

Acid soils containing high levels of aluminum (Al) are known to severely limit plant growth on over 1.6 billion hectares worldwide.
In the United States, a gradual decline in the pH of many soils both in the Great Plains as well as the Southeast, has caused
many soils to become high in levels of free Al. This worldwide condition encouraged the analysis of wheat (Triticum aestivum L. em Thell.), triticale (X Triticosecale Wittmack), and rye (Secale cereale L.) germplasm from one of the major acid soil regions of the world (Brazil) in order to evaluate and compare the genetic
potential of Al genes for cereal improvement. The objectives were to compare Al-tolerance levels in wheats, triticales, and
ryes by measuring root elongation responses in Al-containing hydroponic nutrient solutions. Root elongation was impaired for
all species grown in 1 mg/L concentrations of Al. Rye had the longest root regrowth and Al-sensitive wheats had the shortest
root regrowth. The triticales containing a 2D(2R) substitution developed in the mid-1970s had the poorest root regrowth of
all triticale types. The newly developed advanced triticale lines (AABBRR) yet to be released for commercial production showed
the highest degree of Al tolerance of all the triticale types and approached or exceeded the levels observed in rye. This
indicated that progress is being made in improving Al-tolerance of triticale in Brazil. Of all the old and new wheat varieties
showing the highest degree of Al-tolerance, none of them were better than ‘BH 1146’ a variety that is at least 50 years old.
This indicated that over the past 50 years, although Brazilian wheat breeders have made yield improvements in wheat production,
they have not improved Al-tolerance. Rye showed a higher degree of Al-tolerance than the other cereals when tested in 1 mg/L
of Al, but as expected, some variation was noted.

With the advancement of urban-rural integration, township waterfront functioning as urban waterfront is increasingly emphasized by people. Township waterfront is expected to not only meet the basic needs of urban waterfront in landscape, but also give consideration to both leisure tourism and ecological protection. This paper analyzes the existing problems in the revetment design on the township waterfront and elaborates the importance and feasibility of constructing the ecological revetment in the traditional townships as well as design procedures. The concept of ecological design is introduced into the revetment design on the township waterfront to meet the requirements of both man and nature, so as to achieve a harmonious coexistence between man and nature and sustainable development in a real sense. 相似文献
