In terms of stochastic orders, the purpose of this paper is to show how the random environment can affect the number of working components of a system with heterogeneous components sharing a common random environment. Applications to a class of semiparametric mixture models, stress-strength model and warm standby system are presented. 相似文献

This study overviews the development of 11 Asian equity markets, namely, China, Hong Kong, India, Indonesia, Japan, Korea, Malaysia, Philippines, Singapore, Taiwan, and Thailand. Prior to the onset of the global financial crisis, the Asian stock exchanges were generally bullish, underpinned particularly by China's robust economic performance. Innovations in financial products and services have been growing in importance, as stock exchanges in these countries have been making a concerted effort to introduce new features and best practices, with the objectives of raising market efficiency, enhancing service quality, and generally bringing operations up to par with international standards. But the potential to realize or support market efficiency can only be possible within an adequate legal framework, a sound market infrastructure, and appropriate corporate governance mechanisms. Thus, many challenges are still to be overcome in the region. 相似文献

本文通过汇改以来的月度宏观经济数据分别构建我国的货币状况指数和金融形势指数,并对其进行比较分析。研究结果表明货币状况指数和金融形势指数能够反映我国货币松紧状况,并可以预测通货膨胀率,从而作为货币政策调控的辅助参考指标。分析结果还表明,FCI是通货膨胀率的先行指标,是引起通胀的Granger原因,在控制通胀方面作为指示器要优于MCI。 相似文献

The city of Kaohsiung has been urgently reducing its rates of ownership and usage of privately owned motor vehicles. The most important strategy undertaken thus far has been to build mass rapid transit systems. This study aims to apply the Involvement Theory to construct an inventory to measure level of travelers’ involvement in public transport services. The results indicate that the number of low involvement travelers is the critical factor that determines whether the new public transport system can effectively operate. They also provide authorities with precise marketing strategies targeting different groups in order to allow the new public transport systems to sufficiently meet public needs. 相似文献

This study investigates the influence of consumers’ motivational orientations (“prevention” vs. “promotion”) on their susceptibility to demand‐based versus supply‐based scarcity, measured by purchase intention scores. Prevention‐focused participants were more inclined to adopt a product when it was perceived to be demand‐scarce rather than supply‐scarce, while those who were identified as promotion‐focused responded positively to scarcity attributed to supply shortfall. In addition, products that could be associated with a prevention motive enhanced purchase intentions when presented as demand‐scarce but not if perceived to be supply‐scarce; conversely, products associated with the promotion motive scored better if the scarcity was seen to be supply‐generated rather than demand‐generated. Lastly, messages focused on prevention were more effective than those focused on promotion in the case of perceived demand scarcity, whereas the converse holds true for supply scarcity. These findings highlight the importance of understanding the motivational differences underlying the effectiveness of scarcity appeals. They furthermore suggest the strategic implication that improved intention to purchase occurs when the regulatory focus evoked by a scarcity‐related message is compatible with the appeal it communicates. 相似文献

Passenger orientation (wayfinding) is one of the important factors for the layout design of airport terminals. It is common that some people have difficulties in locating their destinations in spite of availability of wayfinding aids. Visibility index is commonly used to evaluate the ease of wayfinding. However, there is a lack of studies for the determination of the appropriate locations for setting up wayfinding aids in airport terminals so as to enhance the ease of wayfinding. In this paper, a binary linear program is proposed for better allocation of directional signs for wayfinding. The proposed model can be widely applied to practical situations so as to improve the design of signage system in various enclosed environments including airport terminals, multi-function railway stations, and shopping malls. 相似文献
