疏浚大多用于河道的过分淤积,拓宽则用于通水隘口的消除。而随着时空的演变河床疏浚与河槽拓宽的进行所需考虑的因子越来越多,故疏浚进行前应尽量考量整个河道的河性以及施工后可能引致的变动,使能维持预期的效果,并避免造成负面效应。本文主要以涧河为研究对象,利用NETSTARS拟似二维水理输砂模式,探讨河道疏浚后的水理与输砂演变趋势等相关课题。  相似文献

The subject of this study concerns individual vacationers' reactions to the global economic crisis. This crisis is lasting longer than expected, resulting in Europe in a “double dip”. Vacationers can use different strategies to cope with this crisis: from pruning (giving up the vacation) via cheese-slicing (economizing on vacation attributes) to non-economizing. Based on a theoretical framework, it was predicted that over time the pruning segment would become larger than the cheese-slicing segment. A longitudinal study in The Netherlands, covering 4 years, shows economic developments having a relatively minor effect on vacationers' holiday plans and intentions, with no increase in the size of the pruning segment. Six vacationer segments were found, three of which can be considered to be crisis-resistant. Each segment pursues different economizing strategies, with each requiring a customized marketing strategy. Five explanations are proposed for the relatively limited influence of the economic “double dip” on Dutch vacationers. Future research can be directed to comparing vacations with other consumer products, in order to explain the crisis-resistance of vacation planning during this economic crisis.  相似文献

In this paper, I study a model in which shocks to asset prices affect the real sector of the economy through a credit channel. As financial markets become internationally integrated, the economy becomes less vulnerable to domestic asset‐price shocks, but more vulnerable to foreign asset‐price shocks. To the extent that monetary policy stabilization is feasible and desirable, the globalization of financial markets shifts the focus of monetary policy from domestic asset prices to worldwide asset prices.  相似文献

The central intent of this qualitative inquiry is to investigate the benefits, drawbacks, and performance measures of hotel room inventory distribution via flash sales websites. Key advantages and disadvantages of using such a distribution channel fall within the categories of inventory management, revenue management, brand marketing, customer relationships, and operational challenges. The significance of the study is in providing a comprehensive review of the flash sales phenomenon in the lodging industry that may assist hotel managers with the performance evaluation of this distribution channel. Using grounded theory methodology, a flash sales evaluation framework was developed based on 46 phone interviews with hotel managers from different segments of the American hotel industry.  相似文献

This paper analyses the extent to which the level of bank competition influences monetary policy transmission. Using a large panel dataset of 978 banks from 55 countries, and employing the Lerner index model as a measure of market structure, our results show that an increase in banking sector competition weakens the effectiveness of monetary policy on bank lending. The findings are robust to a broad array of sensitivity checks including control of alternative measurements of the Lerner index, different samples and different methodological specifications. By extension, these results have important policy implications for regulators in assessing the effectiveness of monetary policy transmission mechanisms.  相似文献

This study utilizes a macro‐based VAR framework to investigate whether stock portfolios formed on the basis of their value, size and past performance characteristics are affected in a different manner by unexpected US monetary policy actions during the period 1967–2007. Full sample results show that value, small capitalization and past loser stocks are more exposed to monetary policy shocks compared with growth, big capitalization and past winner stocks. Sub‐sample analysis, motivated by variation in the realized premia and parameter instability, reveals that the impact of monetary policy shocks on these portfolios is significant and pronounced only during the pre‐1983 period.  相似文献
