The world's subsurface space, including Britain's, is already used in a variety of ways, ranging from occupancy to disposal and the bulk storage of materials and fuels. In the future it is likely that it will be put to further use in response to trends in technology, resource supply and demand, socioeconomics and geopolitics. Here the present and future uses of underground space, and the potential planning and social issues affecting its development, are reviewed. Future uses are likely to be in the area of increasing occupancy (both commercial and residential), the secure storage of documents and data, the storage of carbon dioxide for carbon abatement, natural gas, compressed air stores of energy from traditional and renewable sources, the use of underground heat in buildings and the proposed deep geological disposal of radioactive waste. The article will also explore pressure points and challenges. These will include the regulation of multiple uses of subsurface storage space and, for projects of national importance including natural gas and radioactive waste storage, legislation to lessen the effect of local opposition relative to the ‘national need’. This article does not discuss future mining, hydrocarbon extraction, or water resources. 相似文献

多伦多大学的OTA:历史及一个核心问题的讨论 总被引:1,自引:0,他引:1
多伦多大学的OTA(教学促进办公室)成立于2002年1月,其职责是改变多伦多大学传统的科研主宰型文化、帮助教师开发教学技能、并通过科学的晋升和薪酬机制确保科研型大学的教师在教学和科研之间建立有效的平衡。这必然涉及到一个最根本的问题:在高级职称的晋升中,卓越的教学业绩是否能与一流的科研成果相提并论?对这一问题,学生、教师、管理层持有不同的观点,西欧、澳洲、北美地区也有不同的做法。 相似文献

The stochastic approach to index numbers has been successfully applied to the estimation of inflation, the world interest rate and international competitiveness.?One distinct advantage of this approach is that it provides the whole distribution of the index, not simply one value. In this article, we extend the stochastic approach to the estimation of a stock market index. We demonstrate how this approach can be used to identify ‘redundant stocks’ that do not contribute significantly to the overall index.?For index tracking purposes, these stocks can be safely excluded. 相似文献

Extreme interannual variability of precipitation within Ethiopia is not uncommon, inducing droughts or floods and often creating serious repercussions on agricultural and nonagricultural commodities. A dynamic climate module is integrated into an economy‐wide model containing a detailed zonal level agricultural structure. This coupled climate‐economic model is used to evaluate the effects of climate variability on prospective irrigation and infrastructure investment strategies, and the ensuing country‐wide economy. The linkages between the dynamic climate module and the economic model are created by the introduction of a climate‐yield factor (CYF), defined at the crop level and varied across Ethiopian zones. Nine sets of variable climate (VC) data are processed by the coupled model, generating stochastic wet and dry shocks, producing an ensemble of potential economic prediction indicators. Analysis of gross domestic product and poverty rate reveal a significant overestimation of the country's future welfare under all investment strategies when climate variability is ignored. The coupled model ensemble is further utilized for risk assessment to guide Ethiopian policy and planning. 相似文献

Volunteers at music festivals play a critical role in festival operation and success. As the music festival industry continues to grow, the ability for these large productions to effectively execute a large volunteer program is augmented. Volunteers from the 2013 Austin City Limits Music Festival were surveyed in regards to their self-image congruency, motivation, satisfaction, and intent to return as a volunteer at the festival. Analysis resulted in three distinct segments which has significant practical implications for festival management. Academic implications exist with the addition of self-image congruency and further discovery of volunteers in the festival and event industry. 相似文献

Progress toward decentralized agriculture in which entrepreneurial initiative of Soviet farm managers could be given fuller range is impeded by the double function of Soviet agricultural prices: as factors affecting input and output decisions and as extractors of land rent. Claims that the Soviet land cadastre inhibits the setting of uniform marginal-cost prices are here examined and found wanting. The real culprits are special interest opposition, ignorance of the potential role of prices, and inability to achieve the necessary complementary reforms, which can be traced to shortcomings in Soviet agricultural economic research and education. 相似文献

Changes in the exchange rate have direct and indirect effects on the prices of domestically produced goods and imports in the domestic market. The direct effects originate with the impact of the exchange rate on the marginal cost of imports; the indirect effects, with its impact on the price of materials used by domestic producers and hence on their marginal costs. Direct and indirect exchange rate pass-through elasticities are estimated for 37 Canadian manufacturing industries and their determinants are examined in a cross-section analysis. It is found that the direct and indirect elasticities are approximately equal in size for domestic goods, while the direct effect is dominant for imports. For a small number of industries, the net result of the direct and indirect effects is that a depreciation of the domestic currency increases the competitiveness of imports, contrary to conventional analysis. Important determinants of the direct (indirect) elasticities are the import share and non-tariff barriers (the responsiveness of domestic costs to changes in the exchange rate, and concentration). 相似文献

A theory of property needs to give an account of the whole lifecycle of a property right: How it is initiated, transferred, and terminated. Economics has focused on the transfers in the market and almost completely neglected the question of initiation and termination of property in normal production and consumption (not in some original state or in the transition from common to private property). The institutional mechanism for the normal initiation and termination of property is an invisible hand function of the market — the market mechanism of appropriation. Does this mechanism satisfy an appropriate normative principle? The standard normative juridical principle is to assign or impute legal responsibility according to de facto responsibility. It is given a historical tag of being "Lockean," but the basis is contemporary jurisprudence, not historical exegesis. Then, the fundamental theorem of the property mechanism is proven, which shows that if "Hume's conditions" (no transfers without consent and all contracts fulfilled) are satisfied, then the market automatically satisfies the Lockean responsibility principle — i.e., "Hume implies Locke." As a major application, the results in their contrapositive form, "Not Locke implies Not Hume," are applied to a market economy based on the employment contract. I show that the production based on the employment contract violates the Lockean principle (all who work in an employment enterprise are de facto responsible for the positive and negative results), and thus Hume's conditions must also be violated in the marketplace (de facto responsible human action cannot be transferred from one person to another — as is readily recognized when an employer and employee together commit a crime).1 相似文献
