遗产:历史表述与历史记忆

"遗产"与"历史"都具有鲜明的时间属性,都与人类的过去、现在和未来相关联。当遗产不再被视为一种现成之物,而被理解为一种与人们对过去的表述和回忆相关的动态过程时,遗产就为理解历史提供了新的可能。一方面历史(过去的事件和行为)是遗产表述的基本内容,是遗产存在和延续的基本框架,也是人们理解、认知遗产的前提和基础;另一方面,今天的遗产运动作为在当下表述过去的一种新实践类型,既是对过去历史记忆的选择与重构,又具有"制造历史"的内在特征。     

Weak representation of the cumulative hazard function under semiparametric random censorship models

In this paper we derive a weak representation of the semiparametric estimator A^se _nof the cumulative hazard function A in the random censorship model. Based on this representation we show that |A^se _n- A| is uniformly bounded in probability up to the last order statistic of the observations.     

Estimation of Periodic Bilinear Time Series Models

In this article, a new class of models is proposed for modeling nonlinear and nonstationary time series. This new class of models, referred to as the periodic bilinear models, has a state space representation and can be characterized by a set of recursive equations. Condition for the stationarity is presented. Procedures for parameter estimation using the cumulants of order less than four are described and the accuracy of the proposed method is demonstrated in the Monte Carlo simulations.     

Linear Combinations,Products and Ratios of Simplicial or Spherical Variates

The density level sets of the two types of measures under consideration are l _{2, p} -circles with p = 1 and p = 2, respectively. The intersection-percentage function (ipf) of such a measure reflects the percentages which the level set corresponding to the p-radius r shares for each r > 0 with a set to be measured. The geometric measure representation formulae in Richter (2009 Richter , W.-D. (2009). Continuous l _{n, p} -symmetric distributions. Lithuanian Mathemat. J. 49:93–108.[Crossref], [Web of Science ®] , [Google Scholar]) is based upon these ipf's and will be used here for evaluating exact cdf's and pdf's for the linear combination, the product, and the ratio of the components of two-dimensional simplicial or spherically distributed random vectors.     

On random walks on affine group

Diaconis' presumption that the number of steps required to get close to uniform for a random walk on the affine group A _pis c(p)p ²with c(p) →ã is verified. We also discuss the random number generation associated with the random walk on the affine group. The number of steps to force the generated number to become random is improved. A modified version of Diacohis-Shahshahani's upper bound lemma is given and applied     

Integral Representation of a Distribution Associated with a Pure Birth Process

ABSTRACT

This article deals with a distribution associated with a pure birth process starting with no individuals, with birth rates λ _n  = λ for n = 0, 2,…, m ? 1 and λ _n  = μ for n ≥ m. The probability mass function is expressed in terms of an integral that is very convenient for computing probabilities, moments, generating functions, and others. Using this representation, the kth factorial moments of the distribution is obtained. Some other forms of this distribution are also given.     

中国Z世代的媒介形象建构及其反思

随着互联网技术的快速发展,Z世代作为拥有特定生命历程的青年群体被社会各界广泛关注。作为概念,Z世代是借助差异性与同一性指代符号而生成的,大众媒介将其形象建构为顺势而生的“数字原住民”、寻求认同的“文化盗猎者”以及彰显风格的“个性消费者”。在“技术+文化”与“技术+消费”的叠加框架中,Z世代媒介形象呈现出多元化的特征,然而积极话语与消极话语之冲突也造成了Z世代媒介形象的内在矛盾。作为一种媒介建构,Z世代的媒介形象虽然再现了社会现实,但也遮蔽了阶层差异、地区差异等现实问题。     

Clinical implications of attachment narratives

This paper discusses attachment theory and research with emphasis on the empirical studies of Many Main. Main's work emphasizes the relationship between an individual's narrative regarding attachment relationships and their underlying internal working model of attachment. The internal working model of attachment is a representation of attachment experience and a set of rules for processing attachment experience. This paper describes various categories of attachment narrative construction and presents a case history that is discussed from an attachment theory perspective.     

The Launch of Banking Instruments and the Figuration of Markets. The Case of the Polish Car-Trading Industry

The paper aims at analyzing the production of creditworthiness within the context of commercial banking in international banks. Taking the interim financing in the Polish automobile sector as an example, the paper reconstructs the process between legal framing of the financial instrument, marketing, and risk management. Firstly, it shows that changes in the state vehicle registry function as a prerequisite upon which the bank uses the newly introduced vehicle registration document as a security. Secondly, it analyzes the change of perspectives which takes place between the marketing of the product (Corporate Banking) and the analysis of documents (Risk Management). Thirdly, it argues that creditworthiness cannot be deduced from the economic representation of the enterprise but is the very result of negotiations between the actors involved.
