核心价值观视域下现代礼仪之构建

核心价值观的培育和践行体现在生活的各个方面,最为重要的是体现在普通民众的言行举止方面。作为人们在长期的生活实践中约定俗成的行为规范与准则,礼仪包含礼貌以及礼节等内容,是现代社会人与人、社会、国家之间交往互动的重要“介质”。社会主义国家中的人际交往应该自觉剔除不符合核心价值观的规范,在个人层面的交往互动上体现诚信和友善,在社会交往层面上体现平等自由,才能最终形成国家层面的文明和谐共处。因此,现代礼仪的构建应该在继承优秀传统和吸收现代文明成果的基础上,形成个人礼节、社会礼仪文化和国家仪式三个层面的内容,并建立相对应的社会机制来设计、制作和推广现代礼仪体系。     

民族认同与国家认同研究述评

民族认同与国家认同的研究一直以来都是学界关注的重点内容之一,学者们为此进行了不懈的努力,成就卓然。文章通过对目前国内外民族认同和国家认同的相关研究成果进行系统梳理,指出通过引入身份认同理论,把群体或个体的意识和行为同文化和社会结构因素联系起来,从综合性、历时性的动态视角来研究民族问题,并由此总结出民族认同与国家认同变迁的规律或机理,将会更好地服务于现实社会。     

Convergence of Discount Time Series Dynamic Linear Models

This article studies the limiting behavior of multiple discount time series dynamic linear models (TSDLMs). It is shown that, under mild conditions, all discount TSDLMs converge to the constant (time-invariant) TSDLM. In particular, the limiting posterior precision matrix of the superposition of multiple discount TSDLMs is explored. For non seasonal models, the elements of the limiting posterior precision of the states are given in a recurrence relationship, while for seasonal models the solution of a linear system provides the elements of the respective limiting precision matrix. The proposed methodology uses canonical Jordan forms and it is illustrated with a detailed example of simulated data featuring both trend and seasonal time series.     

Some further aspects of the löwner-ordering antitonicity of the moore-penrose inverse

A survey is given of known proofs of the antitonicity of the inverse matrix function for positive definite matrices w.r.t. the Lowner partial ordering, and of the corresponding result for the Moore-Penrose inverse of nonnegative definite matrices [the theorem of Milliken and Akdeniz (1977)]. A short new proof of the latter result is obtained by employing an extremal representation of a nonnegative definite quadratic form. Another proof of this result involving Schur complements is also given, and is seen to be extendable to the case of symmetric (not necessarily nonnegative definite) matrices. A geometrical interpretation of Milliken and Akdeniz's theorem is presented. As an application, the relationship between the concepts of greater (maximum) concentration and smaller (minimum) dispersion is considered for a pair (class) of vector-valued statistics with possibly degenerate distributions.     

A test for gamma DFR alternative

In this article, a test for exponentiality against gamma DFR alternative based on a quadratic form of the logarithmic observations is proposed. The percentage points and the power of the test are computed through Monte-Carlo simulation. The test is seen to perform well as compared to a chi-square test proposed by Bain and Engelhardt(1975).     

On the Choice of Functional Forms: Summary of a Monte Carlo Experiment

The use of flexible functional forms is a standard practice in applied econometrics. Many flexible forms have been proposed. In this study, we investigate the behavior of three of them—the translog, the symmetric McFadden, and the symmetric generalized Barnett. Based on Monte Carlo experiments, we assess the ability of these forms to test theoretical properties and to measure technological characteristics.     

Random sampling from the watson distribution

An envelope-rejection method is used to generate random variates from the Watson distribution. The method is compact and is competitive with, if not superior to, the existing sampling algorithms. For the girdle form of the Watson distribution, a faster algorithm is proposed. As a result, Johnson's sampling algorithm for the Bingham distribution is improved.     

《资本论》的历史哲学意蕴

马克思是历史哲学领域中的旗帜性人物。在对以“永恒论”为基调的“一般历史哲学”的“批判性拒绝”中,马克思推出了以“发展论”为核心的“批判的历史哲学”。在《资本论》中,马克思遵循了哲学服务历史的基本取向,并沿着两条并行不悖的路径稳步推进了他的“历史之思”:一是依托于唯物史观的分析范式,深入物质生产领域探掘了历史的本质与规律,二是以政治经济学批判为武器切近现代工商业实践格局,洞悉了资本主义的前景和命运。据此而论,马克思在《资本论》中竭力探掘社会历史的根源并展开对资本主导下的经济运行规则和文化道德机制的实质性批判,确证了以生产方式为基础、以人类解放为核心的“经济基础—上层建筑”的历史哲学运思路向。马克思的历史哲学就是一种基于实践的历史性批判,它在回应“时代之问”中完成了关于人类“历史之谜”的哲学思考。这种历史哲学以“世界历史”为基本定向,以“人类社会”为立脚点,实现了对“当代的自我阐明”,开辟了历史哲学的新境界和开启了人类文明的新方向。     

提升供应链韧性和安全水平推动经济高质量发展的路径

在百年未有之大变局和中国进入高质量发展阶段的背景下,明确中国供应链安全面临的挑战与优势,提升中国供应链韧性和安全水平,是构建新发展格局、实现制造业高质量发展、维护国家经济安全的必然要求。中国供应链安全面临着关键核心技术“卡脖子”、供应链“断链”与产业跨境转移等风险,同时也具备产业体系优势、市场规模优势、举国体制优势和数字基建优势。为增强供应链韧性和安全水平,要以新型举国体制推动关键核心技术突破,推动数字化转型和数智供应链建设,优化制造业产业链高中低端产业布局,发挥超大规模内需市场的稳定作用,推进高水平对外开放,进而推动中国经济高质量发展。
