Multivariate Matsumoto–Yor property is rather restrictive

Matsumoto and Yor [2001. An analogue of Pitman's 2M-X$2M-X$ theorem for exponential Wiener functionals. Part II: the role of the GIG laws. Nagoya Math. J. 162, 65–86] discovered an interesting invariance property of a product of the generalized inverse Gaussian (GIG) and the gamma distributions. For univariate random variables or symmetric positive definite random matrices it is a characteristic property for this pair of distributions. It appears that for random vectors the Matsumoto–Yor property characterizes only very special families of multivariate GIG and gamma distributions: components of the respective random vectors are grouped into independent subvectors, each subvector having linearly dependent components. This complements the version of the multivariate Matsumoto–Yor property on trees and related characterization obtained in Massam and Weso?owski [2004. The Matsumoto–Yor property on trees. Bernoulli 10, 685–700].     

Regression models for functional data by reproducing kernel Hilbert spaces methods

Non-parametric regression models are developed when the predictor is a function-valued random variable X={_Xt}t∈T$X=\{X_t{\}}_{t\in T}$. Based on a representation of the regression function f(X)$f(X)$ in a reproducing kernel Hilbert space such models generalize the classical setting used in statistical learning theory. Two applications corresponding to scalar and categorical response random variable are performed on stock-exchange and medical data. The results of different regression models are compared.

多分销中心供应链模型及其牛鞭效应的H∞控制

本文在文^[1]具有一个分销中心供应链模型的基础上,建立了具有多个分销中心的供应链结构模型,采用供应链上游库存与订货偏差波动之和与下游顾客需求偏差波动之比描述牛鞭效应。提出顾客末端需求波动最差条件下H_∞控制方法,以抑制牛鞭效应。这一方法本质就是供应链末端需求波动最差情况下,制定供应链管理的最优决策。并且以一个石油分销系统为对象进行了供应链牛鞭效应的H_∞控制仿真实验。     

《白孔雀》——劳伦斯哲学探索的起点

劳伦斯的哲学思想贯穿在他的所有作品中,他的第一部小说《白孔雀》则是他以文学的形式探索哲学的起点.他的宇宙观是:宇宙是以对立物而存在的.他在《白孔雀》里着重探讨了理性与直觉、肉体与精神、自然与文明的对立关系.正是这部作品为他今后的创作奠定了基础.     

试论劳伦斯小说对生命哲学的探索

劳伦斯的整个文学创作过程,也是他对生命哲学的探索过程。《白孔雀》,揭示了理性与直觉、肉体与精神、自然与文明的对立关系;《儿子与情人》,继续了性爱题材的生命哲学探索;《虹》与《恋爱中的女人》,则集中展示了劳伦斯的以“血的意识”为标志的生命哲学探索;《查特莱夫人的情人》是他探索生命哲学的“天鹅之歌”,倾注他毕生对人类命运的艺术思考,达到了他探索生命哲学的顶峰。     

新中国60年劳伦斯研究之考察与分析

中国的劳伦斯研究从20世纪30年代开始起步,自80年代起走向繁荣。在80年代,劳伦斯笔下的性描写是学者关注的中心,也鼓舞和启发了中国作家对人性的深入探索。90年代之后,中国学者对劳伦斯研究的范围不断扩大,对其创作中的工业文明与大自然的冲突主题、两性关系主题、死亡与再生主题,非理性心理描写、原始主义等问题都进行了深入探究,也对其作品中的象征隐喻手法进行了全面的分析。精神分析、生态批评、比较文学,以及原型批评、解构主义批评、叙事学、伦理学批评等研究方法,都应用于劳伦斯研究,取得了可观的成绩。另一方面,中国的劳伦斯作品翻译良莠不齐,研究的低水平重复、缺乏学术规范现象也十分严重。     

The transformation of Industrial Citizenship in the course of European integration

The question of the social dimension of European integration has so far remained unsettled. While on the European level, the civil and political dimension of citizenship has been strengthened, the evolution of economic and social rights are unclear, contradictory—and still under-investigated. Our contribution applies citizenship as a central category of modernization theory to inquire into European integration. In particular, our focus is set on the analysis of Economic Citizenship as a specific category of civil rights in the case of Germany. We discuss these dynamics by drawing on the example of three policy fields which illustrate various levels of Economic Citizenship. In this article we are pursuing two goals: Firstly, we revise Marshall's modernization theory against the background of European integration. Secondly, we draw attention to the concept of Industrial Citizenship, which has so far been neglected as a source of further development. We argue that in the process of European integration, industrial rights develop through a double movement, meaning an individual extension of market-based rights complemented through national de-collectivization and—connected to this—a re-stratification of market correcting rights.     

Moderate wage increases and flexible labour contracts to protect employment in Colombian manufacturing

Based on conditional and unconditional demands for labour, we exploit the variations of real minimum wage across manufacturing subsectors to present evidence that this variable affects formal employment. The long-term elasticity of labour demand to the minimum wage is around –0.7. Accordingly, increases in the minimum wage lead to job losses for unskilled labour, mainly in plants with fewer than 100; thus, small increases in the minimum wage are desirable to protect employment. Labour demand is highly cyclical: the output elasticity is about 1.7. Thus, some flexibility in labour contracts is desirable to reduce the link between employment and variation of plants’ sales. Open-ended labour contracts might allow reductions of the nominal wage rather than inducing job losses during periods of severe slumps, as has happened during the COVID-19 pandemic.
