牵动思维与表述功能的现代诗歌欧化语言

从外国诗歌语言中借鉴而来的欧化语言贯穿了整个中国现代诗歌的发展过程。这主要表现为欧化词语的介入、语法与句法的更新以及语言表述方式与诗歌功能的拓展三个层面。尽管其命运坎坷，但已经内化为现代诗歌不可离析的一部分。     

Distribution of linear combination of exponential variates

The exact distribution of a linear combination of n independent negative exponential random variables, when the coefficients of the linear combination are distinct and positive quantities, is well-known. This paper extends the above result to the general case, namely when the coefficients are arbitrary real numbers, positive or negative, distinct or coincident.     

Bayesian variable selection with spherically symmetric priors

We propose that Bayesian variable selection for linear parametrizations with Gaussian iid likelihoods should be based on the spherical symmetry of the diagonalized parameter space. Our r-prior results in closed forms for the evidence for four examples, including the hyper-g prior and the Zellner–Siow prior, which are shown to be special cases. Scenarios of a single-variable dispersion parameter and of fixed dispersion are studied, and asymptotic forms comparable to the traditional information criteria are derived. A simulation exercise shows that model comparison based on our r-prior gives good results comparable to or better than current model comparison schemes.     

On the Product of Inverse Wishart and Normal Distributions with Applications to Discriminant Analysis and Portfolio Theory

Abstract. In this article we analyse the product of the inverse Wishart matrix and a normal vector. We derive the explicit joint distribution of the components of the product. Furthermore, we suggest several exact tests of general linear hypothesis about the elements of the product. We illustrate the developed techniques on examples from discriminant analysis and from portfolio theory.     

On shrinkage m-estimators of location parameters

For a general class of continuous ( and marginally symmetric ) inultivariate distributions, based on suitable M-statistics ( involving bounded but possibly discontinuous score generating functions), shrinkage estimators of location are considered. These estimators are based on the James-Stein type rule and incorporates the idea of preliminary test estimation too. The main emphasis is laid on the study of asymptotic tdistributional ) risk properties of these est-innators, and asymptotic tin-) adraissibility results are also studied under fairly general regularity conditions.     

唐代文殊信仰兴盛的政治背景

文殊信仰在唐代达到顶峰与王权推动有直接关系。从政治角度入手探析其在唐代兴盛的原因。首先,唐初开放性的宗教政策促进了佛教的发展,为其兴盛奠定先机;其次,皇室对文殊道场的推崇在全国范围内强化了文殊信仰的传播和深入;再次,武则天的支持使文殊信仰盛行全国;最后,具护国护王性质的密教文殊信仰顺应"安史之乱"之后的政治需求,获得代宗朝的全力支持而达到信仰顶峰。     

汉代江南铜镜文化

《考古》、《文物》、《考古学报》三大杂志和《湖南出土铜镜图录》、《浙江出土铜镜》等书刊上有较多汉代江南的铜镜资料。汉代江南有发达的铜镜制造文化。固着在铜镜上的花纹、铭文展示了汉代江南人的各种信仰和社会风俗。汉代江南铜镜文化与中原铜镜文化相比既有共性又有突出的个性特征。     

儒家人文信仰的完成——朱熹《四书集注》的思想信仰分析

以《四书》为代表的早期儒学奠定了儒家人文信仰的基础,而理学家朱熹通过重新诠释《四书》完成了儒家的人文信仰。一方面,朱熹以更加理性主义思想方法与概念体系建构以"天理"为中心的哲学体系,以解决人文准则与终极实体之间的内在联系;另一方面,朱熹的理论又是一种宇宙目的的象征性表达,包含着生命体验的终极关切,故明显具有信仰的特征与宗教的功能。     

苏曼殊:无法救赎的自我--兼与李叔同比较

苏曼殊皈依佛门是由于"壮士"的理想无法实现和"美人"的情意不能解脱之后的一种自我救赎,这种皈依是苏曼殊的一种外部行为,并非一种内在的真诚信仰,因此苏曼殊注定无法救赎自我.     

Convexity-based clustering criteria: theory,algorithms, and applications in statistics

This paper deals with the construction of optimum partitions of for a clustering criterion which is based on a convex function of the class centroids as a generalization of the classical SSQ clustering criterion for n data points. We formulate a dual optimality problem involving two sets of variables and derive a maximum-support-plane (MSP) algorithm for constructing a (sub-)optimum partition as a generalized k-means algorithm. We present various modifications of the basic criterion and describe the corresponding MSP algorithm. It is shown that the method can also be used for solving optimality problems in classical statistics (maximizing Csiszárs -divergence) and for simultaneous classification of the rows and columns of a contingency table.
