We develop an efficient algorithm to implement the adjoint method that computes sensitivities of an interest rate derivative to different underlying rates in the co-terminal swap-rate market model. The order of computation per step of the new method is shown to be proportional to the number of rates times the number of factors, which is the same as the order in the LIBOR market model. 相似文献

In the age of growing foreign tourism, providing excellent quality service at hotels is increasingly more important. Service
quality and customer satisfaction have gradually been recognized as key factors used to gain competitive advantage and customer
retention. Most companies conducted satisfaction surveys of their customers, with a view of using analysed results to identify
attributes of potential improvement. However, this kind improvement decisions on the attributes with a lower satisfaction
level needs not to be appropriated. Thus, to achieve higher levels of overall satisfaction with the hotel experience, this
study combined four simple methods, including Kano’s model, refined Kano’s model, Importance-Satisfaction model, and the Improvement
index, to evaluate two types of hotels. The integrated approach of service quality measurement is based on the importance
and satisfaction survey of the quality attributes. The survey, with 24 attributes and service items, were administrated to
a random sample of 400 customers at one business hotel and one resort hotel in Taiwan. The strategies of these two kinds of
hotels were compared and discussed in this study. On the basis of the key quality attributes identified by employing the integrated
approach, which are significantly different from those identified on the basis of a simple satisfaction survey, hotels can
make appropriate decisions on specific areas for improvement to further enhance the hotel service quality in Taiwan. 相似文献

Using the instrumental variable model and the regression discontinuity approach,this paper explores how access to primary education affects the Chinese labor market and helps people to escape poverty.Several important findings are obtained.The popularization of primary education has significantly reduced poverty in China,especially in urban areas.In contrast,the Compulsory Education Law has not been well implemented for older children in rural areas.In addition,the labor market premium for completing primary education is much larger in urban areas than in rural areas.Poor rural school quality might explain this rural-urban disparity.Effort needs to be made to further reduce poverty by ensuring adequate financial resources for primary education in poor areas and improving school quality in rural China. 相似文献

Zhagana Agriculture-Forest-Animal Husbandry Composite System (ZCS) is the first Globally Important Agricultural Heritage Systems site in the Tibetan Plateau. Similar to many traditional agricultural regions, with the development of tourism and leisure agriculture, the peasant households in ZCS have gradually changed their livelihood strategies and livelihood activities in the past 10 years, resulting in the disappearance of some traditional farming methods and agricultural landscapes with a long history. By taking livelihood assets as the entry point and livelihood strategies as the core, this paper analyzed the basic situation of households’ livelihood and the transition mechanism of different livelihood strategies in order to offer suggestions for the dynamic conservation and sustainable development of Agricultural Heritage Systems (AHS). (1) The livelihood strategies of peasant households in ZCS can be divided into two major categories: specialized strategies and diversified strategies. (2) According to the empirical calculation of the livelihood asset accounting framework of AHS, the average livelihood asset value of peasant households in ZCS is 2.040, showing that the situation of peasant households’ livelihood is inadequate. (3) The transition of peasant households’ livelihood strategies from traditional strategy to specialized or diversified livelihood strategies is mainly influenced by natural assets, human assets, cultural assets, social assets and informational assets. In order to meet the growing material and spiritual needs of peasant households and achieve the sustainable development of ZCS simultaneously, it is suggested that the agriculture-forestry-animal husbandry-tourism composite strategies shall be taken as the development direction of peasant households’ livelihood strategies. 相似文献
