从量词看苗汉两种语言的关系

“名物量词”在各种语言中的产生、发展规律不尽一致。因此 ,透过“名物量词”探查两种语言的源流 ,不失为一条可行的途径。从苗汉两种语言量词的统计材料中 ,可以看到两种语言量词的兴起和发展过程。湘西苗语的量词与同时代汉语的量词相比 ,在数量上没有汉语的多 ,在范围上没有汉语的宽。各个历史时期 ,湘西苗语都从汉语借用一批词语 ,相应的汉语量词就跟着进入苗语了。从量词的起源和发展来看 ,苗语深受汉语的影响 ,但是很难说苗汉两种语言出于同一母语。     

立陶宛《能源法》及其对我国能源立法的启示

我国在能源法治建设方面相对滞后,在《能源法》起草过程中广泛借鉴和合理移植国外先进和有益的立法经验已经成为共识。虽然立陶宛在能源和能源资源状况以及能源产业和能源消费结构方面与我国差异明显,但2002年立陶宛《能源法》在处理能源领域基本法与特别法关系以及若干具体制度方面仍然对我国《能源法》的起草具有一定的借鉴意义。     

构建新型政民关系之我见

政府职能的转变和社会自主空间的扩大，对政府与公民的关系产生了相应的影响。政府在其公共政策制定和实施中，必须在追求客观、公正的同时，更加注重法治化、制度化建设，这些都对构建政府与公民良好的互助关系产生积极的作用和影响。     

中东油气与中国石油发展的战略思考

在当前国际环境下,中国的石油安全战略应是开放和外向型的,其核心思想是“保内争外”,即中国政府应进一步加强对中国石油企业参与国际能源合作的宏观指导和支持;中国石油企业应加强国内油气资源的可持续开发和利用,坚持开展国际能源合作,直面国际博弈。中东国家油气资源丰富,且与中国关系友好,应是中国石油企业对外开展能源合作的首选地区。     

Ecocultural Attributes: Evaluating Ecological Degradation in Terms of Ecological Goods and Services Versus Subsistence and Tribal Values

It is becoming increasingly clear that scientists, managers, lawyers, public policymakers, and the public must decide how to value what is provided by, and is a consequence of, natural resources. While “Western” scientists have clear definitions for the goods and services that ecosystems provide, we contend that these categories do not encompass the full totality of the values provided by natural resources. Partly the confusion results from a limited view of natural resources derived from the need to monetize the value of ecosystems and their component parts. Partly it derives from the “Western” way of separating natural resources from cultural resources or values, and partly it derives from the false dichotomy of assuming that ecosystems are natural, and anything constructed by man is not natural. In this article, we explore the previous assumptions, and suggest that because cultural resources often derive from, and indeed require, intact and unspoiled natural ecosystems or settings, that these values are rightly part of natural resources. The distinction is not trivial because of the current emphasis on cleaning up chemically and radiologically contaminated sites, on restoration of damaged ecosystems, on natural resource damage assessments, and on long‐term stewardship goals. All of these processes depend upon defining natural resources appropriately. Several laws, regulations, and protocols depend upon natural resource trustees to protect natural resources on trust lands, which could lead to the circular definition that natural resources are those resources that the trustees feel they are responsible for. Where subsistence or tribal peoples are involved, the definition of natural resources should be broadened to include those ecocultural attributes that are dependent upon, and have incorporated, natural resources. For example, a traditional hunting and fishing ground is less valued by subsistence peoples if it is despoiled by contamination or physical ecosystem degradation; an Indian sacred ground is tarnished if the surrounding natural environment is degraded; a traditional homeland is less valued if the land itself is contaminated. Our argument is that intact natural resources are essential elements of many cultural resources, and this aspect requires and demands adequate consideration (and may therefore require compensation).     

不同减排合同下企业间纵向持股对供应链决策的影响

本文针对节能服务公司融资难、回款难及其与用户之间缺乏信任等现象,结合实际中节能服务公司与制造企业采取的不同减排合同机制,分别构建了减排效益分享型合同和减排量保证型合同下企业间纵向持股的三级低碳供应链模型,并对比分析了不同减排合同下持股策略对供应链企业决策及利润的影响。通过模型分析并结合案例及数值算例发现,在减排效益分享型合同中,当制造商单独持股节能服务公司时,增加持股比例会使产品减排量和链条上其他成员利润增加,同时低碳产品市场价格增加;当零售商和制造商同时持股节能服务公司时,两公司增加持股比例同样会使企业决策和利润得到优化,实现真正意义上的供应链企业大联盟,但该种情形会加大持股比例与企业决策和利润的协调难度。此外,在减排效益分享型合同下,制造商对节能服务公司持股可使环保红利和企业效益均得到增加,建议此种减排模式下的供应链企业实施持股策略;但对于减排量保证型合同,持股策略对各企业决策及利润并无明显改善,因此该种减排合同下不建议企业间采取股权合作策略。     

Energy conservation through resource-aware movement in heterogeneous mobile ad hoc networks

Energy conservation in mobile ad hoc networks is of paramount importance because most mobile nodes usually have very limited energy supply. Previous research on this issue focused on the design at the network or MAC or physical layer. In this paper, we study this problem from the new perspective of node mobility, i.e., analyzing the impact of node movement on energy conservation. In particular, armed with the inherent resource heterogeneity in mobile ad hoc networks, we propose a novel resource-aware movement strategy to make better use of some powerful nodes to achieve energy conservation. We also formulate the resource-aware movement as a NP-complete distance-constrained least-cost (DCLC) routing problem and propose an efficient heuristic solution. Extensive simulations have been used to demonstrate the effectiveness of the proposed schemes.     

Layouts for ocean wave energy farms: Models,properties, and optimization

Renewable energy, such as wave energy, plays a significant role in sustainable energy development. Wave energy represents a large untapped source of energy worldwide and potentially offers a vast source of sustainable energy. We present models and a heuristic algorithm for choosing optimal locations of wave energy conversion (WEC) devices within an array, or wave farm. The location problem can have a significant impact on the total power of the farm due to the interactions among the incident ocean waves and the scattered and radiated waves produced by the WECs. Depending on the nature of the interference (constructive or destructive) among these waves, the wave energy entering multiple devices, and thus the power output of the farm, may be significantly larger or smaller than the energy that would be seen if the devices were operating in isolation. Our algorithm chooses WEC locations to maximize the performance of a wave farm as measured by a well known performance measure called the q-factor, which is the ratio of the power from an array of N WECs to the power from N WECs operating independently, under the point absorber approximation. We prove an analytical optimal solution for the 2-WEC problem and, based on the properties of the 2-WEC solution, we propose an iterative heuristic optimization algorithm for the general problem.     

布莱尔对英国工党与工会关系的定位与调整论析

基于1980年代以来工党和保守党处理工会问题的经验教训以及工会的新变化,1994年出任工党领袖的布莱尔把对工会的定位由工党的劳工运动盟友转变为社会合作伙伴,对工会开始采取疏远和强硬的态度,尽力削弱附属工会在党内的权力。布莱尔对工党与工会关系的调整总体上是成功的,但也产生工党失去身份特征、核心选民减少等问题,对此要给予全面辩证地认识。     

Scrambled systems: the (im)mobilities of ‘storm Desmond’

This article examines a 3-day blackout, triggered by a ‘1-in-100-year’ rainfall event. Storms and floods account for almost three-quarters of weather-related disasters, and are typically accompanied by cascading infrastructure failures, which pattern and amplify their effects in highly significant ways. Such disruptions reveal aspects of everyday life that ordinarily remain obscure, including capacities for resilience embodied in people, cities and infrastructure. The article proposes that disruption events be understood in terms of ‘scrambles’, as they involve abrupt demobilisation and remobilisation of a range of people and materials. The article firstly examines the astonishing capacity for failure latent in ‘pervasively powered’ arrangements, as well as the many ways in which people and things were ‘scrambled’ in response. The article then proceeds to explore the ways in which vulnerabilities result in part from mobilisation in response to previous disruption events, before examining the ‘circuits’ that link far-flung places in mobile disaster geographies, global patterns of electricity dependence, the rise of data overload in the ‘cloud’ to carbon overload in the atmosphere. The article concludes by presenting further evidence in support of the thesis that disruptions and disasters are part of a ‘new normal’, and what this means for prevailing sociotechnical arrangements reliant on ‘sunk’ infrastructure.
