Parameter estimation of a composite production function model based on improved artificial fish swarm algorithm and model application

The traditional Cobb–Douglas production function uses the compact mathematical form to describe the relationship between the production results and production factors in the production technology process. However, in macro-economic production, multi-structured production exists universally. In order to better demonstrate such input–output relation, a composite production function model is proposed in this article. In aspect of model parameter estimation, artificial fish swarm algorithm is applied. The algorithm has satisfactory performance in overcoming local extreme value and acquiring global extreme value. Moreover, realization of the algorithm does not need the gradient value of the objective function. For this reason, it is adaptive to searching space. Through the improved artificial fish swarm algorithm, convergence rate and precision are both considerably improved. In aspect of model application, the composite production function model is mainly used to calculate economic growth factor contribution rate. In this article, a relatively more accurate calculating method is proposed. In the end, empirical analysis on economic growth contribution rate of China is implemented.     

Testing homogeneity in semiparametric mixture case–control models

Parametric and semiparametric mixture models have been widely used in applications from many areas, and it is often of interest to test the homogeneity in these models. However, hypothesis testing is non standard due to the fact that several regularity conditions do not hold under the null hypothesis. We consider a semiparametric mixture case–control model, in the sense that the density ratio of two distributions is assumed to be of an exponential form, while the baseline density is unspecified. This model was first considered by Qin and Liang (2011 Qin, J., Liang, K.Y. (2011). Hypothesis testing in a mixture case–control model. Biometrics 67(1):182–198.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar], biometrics), and they proposed a modified score statistic for testing homogeneity. In this article, we consider alternative testing procedures based on supremum statistics, which could improve power against certain types of alternatives. We demonstrate the connection and comparison among the proposed and existing approaches. In addition, we provide a unified theoretical justification of the supremum test and other existing test statistics from an empirical likelihood perspective. The finite-sample performance of the supremum test statistics was evaluated in simulation studies.     

浅析和服图案中的自然崇拜

太平洋地震带所带来的天灾,海洋带来的自然恩惠,让大和民族对自然既敬畏又依赖,进而发展出咏诵自然的“物哀”之情,对自然的情感激发了对“现世”的感怀和珍惜,这样的情感反映在他们的服饰文化上,尤其是图案上.他们从邻邦中国引入了汉族的服饰形制,结合本土的自然风物,创造出独特的纹饰图案.     

后现代视野与文学经典问题域的新问题

本文以我国文学经典问题域业已形成为基本判断,全面和历史性地梳理了其形成原因和过程,分析了问题域中诸问题之间的逻辑关系,目前面临的研究困境等。籍此提出文学经典重读的问题,旨在从文学经典现象和重读主体实践活动角度,从该问题的界定、研究目的和重读对象的确定等基本方面做了交代。最后,提出文学经典重读问题需要置于现代与后现代相互交融的"思考和感觉方式"中。     

知识主体的突进与退隐:从笛卡尔到福柯

在西方哲学的知识论传统中,哲学家们倾向于把主体和客体理解为他们各自规范的知识观念所要求的必要功能。在古代哲学家们的思想中,自然和客体知识的可能性问题受到主要讨论,但没有明确地思考主体问题。近现代主体观的兴起所依赖的个体观念只是在后来的基督教思想中才进入哲学传统。以个体观念为先决条件的个体责任的观念已然现身于奥古斯丁的著作中。奥古斯丁对自我的直接诉求,天才般地开启了笛卡尔的"我思"观念的源头。由此形成的笛卡尔的知识主体,是一个抽象的认识论的假定,一个消极的旁观者。康德有限度地追随了笛卡尔的主体观念,但把笛卡尔的作为消极的旁观者的主体改造成了积极的行动者。康德在知识观上的这种"哥白尼式的"革命,构成了随后德国唯心主义主体观的基础。整体上看,康德之后的主体观存在着一种越来越向笛卡尔的主体观和古希腊的主体观隐退的明显倾向,及至海德格尔后期和后结构主义,这种倾向最终导致了向古希腊知识主体的全面回归。

基于制造业转移的长三角地区产业结构优化研究

经济增长发展到一定阶段,必然伴随着产业结构的调整和优化。中国制造业虽大但不强,多数企业尚处于产业链中低附加值的底部。制造业转移,特别是我国如何承接国际制造业转移是值得关注的话题。对于区域而言,制造业转移对于区域产业结构的优化具有促进作用,选择合适的主导产业是长三角地区产业结构优化的重要路径。长三角地区制造业转移促进产业结构优化的实证研究结果表明,制造业的转移对产业结构优化具有较为显著的影响。长三角地区应当在科学发展观的指引下,遵循制造业发展规律和产业结构优化规律,积极推动制造业在不同地区间的转移。     

论高校协商民主管理模式的建构

由于民主涵义的复杂性和实际操作中的选择偏好,当前中国高校在民主管理模式上往往重视代议民主,而轻视或忽略协商民主.协商民主是代议民主的必要补充,它有助于解决代议民主在实际运作中存在的不足,对于维护广大师生合法权益、提高高校公共决策质量、培养师生公民人格和精神具有重要的实践意义.当前中国高校的协商民主管理模式建构,可以在参与主体的广泛性、参与事务的公开性、参与问题的价值性、参与过程的论辩性、参与行为的有效性等方面重点展开,从而为和谐校园的创建奠定政治基础.     

以红色文化推进马克思主义大众化的基本路径探析

推广红色文化是推进马克思主义大众化的重要隐性教育方式,当前以红色文化推进马克思主义大众化,需要进一步加大红色文化资源的宣传营销力度,不断提高其马克思主义大众化载体的现实影响力;努力建立红色文化精神产品体系,不断强化马克思主义理论的市场渗透力和感染力;着力开发红色旅游资源,不断增强大众对马克思主义理论的体验性认同。
