病毒性心肌炎患者血清 SOD 与心肌炎特异性标志物的相关性研究

为探讨病毒性心肌炎患儿超氧化物歧化酶（ SOD）与心肌炎特异性标志物的相关性及其临床意义，将48例小儿病毒性心肌炎患者作为实验组，以48例健康儿童作为对照组，检测实验组和对照组血清中心肌肌钙蛋白（ cTnT）、超敏C反应蛋白（ HS-CRP）、肌酸激酶同工酶（ CK -MB）和 SOD，评价其相关性。结果为：实验组cTnT、HS-CRP和CK-MB水平明显高于对照组（P＜0．05），SOD 的活性明显低于对照组（P＜0．01）；治疗3周后 cTnT、HS -CRP 和 CK -MB 水平明显降低（P ＜0．05）， SOD的活性明显升高（P＜0．01），与cTnT、HS-CRP和CK-MB 水平呈负相关（P＜0．05）。 SOD、cT-nT、HS-CRP、CK-MB均参与了病毒性心肌炎的发病过程。     

我国信托业市场结构与绩效关系研究

我国信托业的经营绩效与市场份额之间存在显著的正相关关系，与市场集中度存在弱性的负相关关系。现阶段我国信托市场还处于垄断程度较低的低中占寡型市场，信托业绩效水平的提升有赖于市场份额、营业费用率、资产负债率等影响因素的进一步优化。     

Fast delta computations in the swap-rate market model

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.     

Using integrated quality assessment for hotel service quality

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.

进一步提高中国花卉产业国际竞争力对策研究

进入21世纪以来,我国花卉产业一直呈现出快速发展的态势,生产规模已居世界首位,但也存在着横向扩展过快、纵向挖潜不足的问题。在国际竞争日益激烈的背景下,新兴花卉生产国哥伦比亚、肯尼亚、马来西亚已分别成为全球最大的康乃馨、玫瑰和菊花的生产、出口基地,印度、越南等国也在迅速崛起。中国花卉产业应该通过合理有效的制度创新,建立经营型行业协会,加强物流体系建设,引导资源禀赋优势向竞争优势转变。     

Poverty Reduction in China： The Contribution of Popularizing Primary Education

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.
