巨灾风险债券的契约条款是债券交易各方权利义务关系的载体。基于剩余索取权与控制权对应的一般原则,必须在理顺债券运行中多方主体的权利义务关系,因为巨灾风险债券的条款设计须解决的一个核心问题,也不例外的在于如何平衡债权债务双方的权利义务关系,保证债券的顺利运作。但是,在进行巨灾风险债券契约条款设计时,必须比较巨灾风险债券在现金流结构、信用结构和期权结构上与一般债券的异同,在债券契约条款设计中应包含一些限制性条款,以便巨灾风险债券的契约条款的科学性。 相似文献

Graphical Models for Composable Finite Markov Processes 总被引:1,自引:0,他引:1
VANESSA DIDELEZ 《Scandinavian Journal of Statistics》2007,34(1):169-185
Abstract. Composable Markov processes were introduced by Schweder (1970) in order to capture the idea that a process can be composed of different components where some of these only depend on a subset of the other components. Here we propose a graphical representation of this kind of dependence which has been called 'local dependence'. It is shown that the graph allows to read off further independencies characterizing the underlying Markov process. Also, some standard methods for inference are adapted to exploit the graphical representation, e.g. for testing local independence. 相似文献

This article presents theoretical elements concerning the ‘nature versus culture’ confrontation as a particular aspect of the worldwide expansion of Western civilization. Several speculations are made concerning the philosophical foundations which have provided the base for the current political and economic mega-scenarios in the contemporary world. We turn our attention to the articulations of the concept of nature with the processes of mondialization of Western culture and with the history of universal culture. Finally, several considerations are made on the dynamics of economic processes on a world scale and projections on the impact of science and technology in the social and political frames that are taking place in the contemporary world. 相似文献

社会风险治理是社会治理的重要组成部分,增强基层政府社会风险治理能力是推进国家治理体系和治理能力现代化的一大关键。随着我国社会的进一步转型,社会风险呈现出虚拟化、网络化、联动化等新态势,它使得基层政府社会风险治理面临着新的挑战。因此,需要从流程优化的角度,对基层政府社会风险治理的机制与方式进行创新,从而提高基层政府社会风险治理的水平。 相似文献

Research on same‐sex relationships has informed policy debates and legal decisions that greatly affect American families, yet the data and methods available to scholars studying same‐sex relationships have been limited. In this article the authors review current approaches to studying same‐sex relationships and significant challenges for this research. After exploring how researchers have dealt with these challenges in prior studies, the authors discuss promising strategies and methods to advance future research on same‐sex relationships, with particular attention given to gendered contexts and dyadic research designs, quasi‐experimental designs, and a relationship biography approach. Innovation and advances in the study of same‐sex relationships will further theoretical and empirical knowledge in family studies more broadly and increase understanding of different‐sex as well as same‐sex relationships. 相似文献

采用纵贯研究、内容分析、深度访谈相结合的定性研究方法,以推动我国物联网产业发展的3个宏观政策决策过程为研究对象,旨在讨论政企互动是如何帮助政府进行不确定性管理的.研究结论表明:新兴产业的宏观政策决策是由数个存在递进关系的渐进式阶段组成,而每个渐进式事项的解决依赖于众多在政企互动中形成的微观政策工具的实施.政企互动帮助政策决策者通过4种机制(信息获取、行动协调、企业行动承诺和政府政策承诺)实现了对因信息缺乏以及对产业行动者资源依赖所造成的不确定性的管理. 相似文献

Psychological theories often posit the existence of several different states. Individuals are viewed as belonging to one of the states at a given age, but with development pass to another state. A main problem in evaluating such theories is representing the transition from one state to another over age. A stochastic transition framework is proposed which should be useful in many different settings. The model is illustrated with data from a cognitive development task. 相似文献

Bathtub distributions are characterized by bathtub failure rate functions . These are possibly more realisitic models than the monotone failure rate models . A systematic account of such distributions is not available and this review aims to give such an account . We give some easily verifiable conditions to check the bathtub property of a distribution along with methods to construct such distributions . We also discuss some stochastic and reliablity mechanisms which lead to bathtub distributions. These include mixtures ( stochastic failure rate models ) , series system , stochastic differential equation models and so on. We also review inference on bathtub distributions. The paper concludes with a rather exhaustive list of bathtub distributions. 相似文献

Recently, cumulative residual entropy (CRE) has been found to be a new measure of information that parallels Shannon's entropy (see Rao et al. [Cumulative residual entropy: A new measure of information, IEEE Trans. Inform. Theory. 50(6) (2004), pp. 1220–1228] and Asadi and Zohrevand [On the dynamic cumulative residual entropy, J. Stat. Plann. Inference 137 (2007), pp. 1931–1941]). Motivated by this finding, in this paper, we introduce a generalized measure of it, namely cumulative residual Renyi's entropy, and study its properties. We also examine it in relation to some applied problems such as weighted and equilibrium models. Finally, we extend this measure into the bivariate set-up and prove certain characterizing relationships to identify different bivariate lifetime models. 相似文献
