A J‐function for Inhomogeneous Spatio‐temporal Point Processes

We propose a new summary statistic for inhomogeneous intensity‐reweighted moment stationarity spatio‐temporal point processes. The statistic is defined in terms of the n‐point correlation functions of the point process, and it generalizes the J‐function when stationarity is assumed. We show that our statistic can be represented in terms of the generating functional and that it is related to the spatio‐temporal K‐function. We further discuss its explicit form under some specific model assumptions and derive ratio‐unbiased estimators. We finally illustrate the use of our statistic in practice. © 2014 Board of the Foundation of the Scandinavian Journal of Statistics

Bayesian optimal design for changepoint problems

We investigate Bayesian optimal designs for changepoint problems. We find robust optimal designs which allow for arbitrary distributions before and after the change, arbitrary prior densities on the parameters before and after the change, and any log‐concave prior density on the changepoint. We define a new design measure for Bayesian optimal design problems as a means of finding the optimal design. Our results apply to any design criterion function concave in the design measure. We illustrate our results by finding the optimal design in a problem motivated by a previous clinical trial.

浅论社会主义精神文明建设中的强制

社会主义精神文明建设中的强制是制定和强化社会主义精神文明建设中人们的权利义务关系、道德责任以及必须遵守的公共规则，以此来规范人们的行为，促进精神文明建设。现阶段，我国社会主义精神文明建设中的强制包括法律、道德和制度三种类型。在实践中，应把积极的引导、思想教育同外在的强制有机结合起来，促进全社会精神文明的发展。

A Note on the Characterization of Positive Linnik Laws

Recently, Jayakumar & Pillai (1996) gave an interesting characterization of the positive Linnik laws in terms of the spectrum function of an infinitely divisible law. This paper improves their result and simplifies their proof. It proves another characterization result in terms of the Pareto law. Further, it represents the positive Linnik random variable as a function of independent gamma random variables.

医疗体制改革的深入和市场经济的发展使医患关系发生了巨大变化 ,医患关系变成了法律或合同关系、经营者与消费者关系 ,患者已从过去的求医变成了现在的选择医生。如何应对这些变化 ?作者认为 ,医务人员应通过转变观念、依法行医、给患者提供优质服务等来建立市场经济条件下的融洽、相互信赖与尊重的新型医患关系     

高校体育场馆对外有偿服务若干因素探析

对影响中国高校体育场馆有偿服务的因素进行分析,影响体育场馆有偿服务的因素主要是学校的地理位置、场馆规模及设施是否齐全等方面。高校可以通过采取制订合理政策、培养人们的体育消费意识、建立健全运营机制、拓展经营项目、加强对外宣传、吸纳社会资金、建立综合性体育休闲中心等对策,提高场馆有偿开放程度。     

Comparing two treatments in terms of the likelihood ratio order

In this paper new families of test-statistics are introduced and studied for the problem of comparing two treatments in terms of the likelihood ratio order. The considered families are based on φ-divergence measures and arise as natural extensions of the classical likelihood ratio test and Pearson test-statistics. It is proven that their asymptotic distribution is a common chi-bar random variable. An illustrative example is presented and the performance of these statistics is analysed through a simulation study. Through a simulation study it is shown that, for most of the proposed scenarios adjusted to be small or moderate, some members of this new family of test-statistic display clearly better performance with respect to the power in comparison to the classical likelihood ratio and the Pearson's chi-square test while the exact size remains closed to the nominal size. In view of the exact powers and significance levels, the study also shows that the Wilcoxon test-statistic is not as good as the two classical test-statistics.     

考虑投资者情绪的中国股市自激发效应研究

本文在极值理论中引入行为金融学，结合标值自激发点过程（MSEPP）刻画股指收益率极端值序列的集聚性、短期相依性，并将传统的超阈值模型所描述的齐次泊松过程拓展为非齐次泊松过程，探讨投资者情绪对极端收益率的冲击。运用风险偏好指数的方法，基于沪深300指数成份股合成中国投资者情绪指数（EMSI），进一步构建MSEPP-EMSI模型预测沪深300指数、上证综合指数及深圳成分指数的极端风险爆发概率，并对其进行动态ES风险测度。实证结果表明，沪深股市在短期内股指连续暴跌现象时有发生，投资者极度负面情绪会加剧股市的剧烈动荡，当考虑投资者情绪对极端风险的冲击时，MSEPP-EMSI模型能有效的提高对极端风险的概率预测精度及ES预测精度。
