巴里温斯顿(Barry Winston),这名专门负责时代广场的标志专家说:“Walgreens已经为入驻时代广场做出了一个新的构想,其中包括一个令人惊叹的LED显示屏,那将是迄今为止在时代广场出现过的最大,最独特的LED显示屏。“  相似文献

This article argues that lessons on how to achieve a sustainable financial system can be learnt from the work done on sustainable commons (on common‐pool resources – CPRs – where there is no ‘tragedy of the commons’). Existing approaches to financial regulation may not give proper attention to available solutions. The article proposes that innovative solutions could be tested using experimental methods commonly used in CPRs: repeat run, feedback driven games.  相似文献

Recent events have sparked renewed interest in disaster mitigation for public infrastructures. Presidential Decision Directive 63 identifies water distribution as being among the most vital and vulnerable of our large-scale infrastructures. Water distribution networks are vulnerable to threats such as chemical and biological contamination, cyber attacks on computer-based management systems, and physical destruction from acts of nature and intentional attack. This research develops methods for configuring the undamaged portion of the water network to mitigate the consequences of physical destruction. The approach is to find a hydraulically feasible residual network that can be pressurized to meet the demand of a subset of demand sectors. Demand sectors not pressurized then receive water through truck distribution from pressurized sectors. The objective is to minimize weighted water shortage and water truck distribution costs by identifying sectors to pressurize along with an assignment of unpressurized sectors to pressurized sectors for water delivery by truck. The paper develops an optimization model, describes a solution method, and presents computational results for three example networks.  相似文献

This paper presents estimates of export and import demand functions for the G7 economies over the period 1956 to 1995 and over two sub-periods 1956-73 and 1974-95. These estimates are used to construct predictions of the equilibrium growth rates for these economies by use of the 'Thirlwall's Law' relationship. The estimates are consistent with observed cross country growth patterns over the whole sample and the post 1973 period but are less convincing in the pre 1973 sub-period. It is argued that the slowdown in economic growth after 1973 can be partly explained by the growing internationalisation of the world economy coupled with a slowdown in the overall growth of world trade.  相似文献

The paper analyzes empirical evidence from 368 environmentally responsive small and medium-sized enterprises (SMEs) operating in four industries. The results demonstrate that firms' environmental performance cannot be viewed as a one-dimensional concept and that determinants of firms' environmental performance depend on the dimension retained. The impacts of firms' environmental performance on their innovativeness and competitiveness vary according to the industry within which they operate. However, impacts on product and process innovations as well as on managerial innovations are positive and significant in all four industries.  相似文献

English local authorities are expected to promote 'effective community engagement'. The ways in which they can do this are various, ranging from the provision of information to direct involvement in decision-making. This paper focuses on the impact of adopting different types of community engagement strategy on local democracy. Two principal types of community engagement strategy are identified: consumerist and participatory, and their potential for encouraging effective engagement is discussed, before their implications for local democracy are modelled. The paper argues that the relative priority accorded to different types of community engagement are likely to cause local democracy to evolve towards consumer, stakeholder, radical or citizen-centred democracy.  相似文献
