Continuity Estimates for Ruin Probabilities

A method of continuity analysis of ruin probabilities with respect to variation of parameters governing risk processes is proposed. It is based on the representation of the ruin probability as the stationary probability of a reversed process. We apply Kartashov's technique designed for continuity analysis of stationary distributions of general Markov chains in order to obtain desired continuity estimates. The method is illustrated by the Sparre Andersen and Markov modulated risk models.     

项目挣值的绩效差异分析方法缺陷与解决方案

Does mandatory food safety training and certification for restaurant employees improve inspection outcomes?

The purpose of this study was to explore the relationship between mandatory food safety training and certification and inspection results of chain restaurants and independent restaurants, using current food safety inspection results of food service establishments in Central Florida. More specifically, this study examines whether there is any statistically significant difference in the violation frequency among chain and independent restaurants. Reducing the risk of any foodborne illness is a critical strategy that industry stakeholders should pursue in an area dominated by tourism such as Orlando, Florida. A one-way ANOVA was used to determine the differences between the two types of restaurants. Findings indicate that there is significant difference between chain and independent restaurants for critical violations. No difference was found when comparing chain verses independent restaurants for non-critical violations.     

The value contribution of strategic foresight: Insights from an empirical study of large European companies

This paper focuses on exploring the potential and empirically observable value creation of strategic foresight activities in firms. We first review the literature on strategic foresight, innovation management and strategic management in order to identify the potential value contributions. We use survey data from 77 large multinational firms to assess how much value is generated from formalized strategic foresight practices in these firms. We show that it is possible to capture value through (1) an enhanced capacity to perceive change, (2) an enhanced capacity to interpret and respond to change, (3) influencing other actors, (4) and through an enhanced capacity for organizational learning.     

社会和谐：转型期社会建设的重要价值目标

社会和谐是指社会关系中的各种要素处于相互依存、相互协调、相互促进的状态，表现为人际关系和谐、人与社会关系和谐、人与自然关系和谐、人自身和谐四种形式。紧迫性、前瞻性和远景性是影响我国社会和谐的三种形态。因此，促进社会和谐，应从解决那些已经和正在危及社会和谐的问题．解决和消除那些可能危及社会和谐的隐患以及构建一种合理的社会结构三个层面着手。

Size,value, and momentum in developed country equity returns: Macroeconomic and liquidity exposures

The paper investigates value and momentum factors in 23 developed international stock markets. We find that typically value and momentum premia are smaller and more negatively correlated for large market capitalization stocks relative to small. Momentum factors are more highly correlated internationally relative to value. We provide international evidence on three sets of risk exposures of value and momentum returns: macroeconomic risk, funding liquidity risk, and stock market liquidity risk. We find that value returns are typically lower prior to a recession while momentum returns often exhibit little sensitivity. Value returns are typically lower in times of poor funding liquidity, whereas, with notable exceptions, momentum returns are typically unaffected. Lastly, for almost all countries, value returns are high in poor stock market liquidity conditions.     

PSC指标在VFM评价中的应用研究

英国是PFI/PPP模式的发起者和主要推广者。采用了PSC指标为基准的评价方法来获得最佳的VFM。本文研究表明:PSC指标的应用随着PPP项目在全球的开展并不具有广泛意义,分别受到来自实践和理论的质疑。这对建立我国的VFM评价体系有一定启示作用。
