LENGTH-BIASING, CHARACTERIZATIONS OF LAWS AND THE MOMENT PROBLEM

A positive random variable X with a finite mean has an induced length-biased law represented by Y, and Y is stochastically larger than X. An independent uniform random contraction of Y, UY, has the same law as X if and only if the latter is exponential. This property is extended to non-uniform contractions and a more general notion of length-biasing. The distributional equality of X and W leads to a functional equation for the moment function of X, which has either Infinitely many solutions or none. When U is constant, X can have a log-normal law, but it can also have laws with the same moment sequence as this log-nod law. The case where U has a certain beta, or generalized beta, law give t3 characterizations of generalized gamma laws, or to products of independent copies of them. This occurs even when these laws are not determined by their moment sequences.     

Generalized Laplacian approximations in Bayesian inference

This paper presents a new Laplacian approximation to the posterior density of η = g(θ). It has a simpler analytical form than that described by Leonard et al. (1989). The approximation derived by Leonard et al. requires a conditional information matrix R_η to be positive definite for every fixed η. However, in many cases, not all R_η are positive definite. In such cases, the computations of their approximations fail, since the approximation cannot be normalized. However, the new approximation may be modified so that the corresponding conditional information matrix can be made positive definite for every fixed η. In addition, a Bayesian procedure for contingency-table model checking is provided. An example of cross-classification between the educational level of a wife and fertility-planning status of couples is used for explanation. Various Laplacian approximations are computed and compared in this example and in an example of public school expenditures in the context of Bayesian analysis of the multiparameter Fisher-Behrens problem.

西部地区投资管理体制存在的主要问题及影响因素分析

西部现行投资体制存在着企业的投资主体地位尚未确立,政府职能转变滞后,金融支持弱化,市场化融资机制尚未形成,法规制度建设有待完善等问题。改革政府投资体制必须考虑到投资活动自身的特点、整个经济体制和管理制度、经济发展的不同阶段、市场经济体制对投资改革的要求、政府投资的功能特点和WTO规则对投资管理的要求。     

非传统安全视角下的云南跨界民族问题

冷战结束后,云南边境地区的安全因素发生了重大变化,安全威胁由防御邻国向我国侵犯等传统安全要素逐渐转向防止各种跨国犯罪和贩毒走私为特征的非传统安全,跨界民族问题成为引发云南边疆地区非传统安全的重要因素之一,给边疆安全带来前所未有的挑战。从云南跨界民族问题与非传统安全关系入手,分析由云南跨界民族所产生的非传统安全问题,提出解决云南跨界民族问题的一些设想,是十分必要的。
