论大数据时代背景下宏观调控决策的法治化

大数据正以难以想象的速度给社会带来新的商业变革、管理变革乃至思维变革,在宏观经济调控领域,大数据带来的变革对国家的宏观调控既提供了机遇又提出了挑战。在宏观调控决策过程中,我们要适应大数据时代的新要求,加强宏观调控决策的独立性、参与性和透明化,对调控的专业性与民主性进行协调和保障,做到以数据为核心,对决策数据（信息）的收集、公开、处理、保护分别进行相应的法律调整,做好多层次的制度设计,才能用宏观调控决策的法治化来提高宏观调控的有效性。     

布依族稻作文化及其起源

布依族是我国最早种植水稻的民族之一,它以善于种植水稻著称于世.在布依族社会生活的各个方面都呈现着浓郁的稻作文化特色.布依族稻作文化源远流长,其起源可以追溯到母系社会时代,我国南方古越人及其先民的稻作文化是布依族稻作文化的源头.     

A Note on the Invariance Law for Surrogate Dimension Reduction

In this article, we give an alternative and much shorter proof for the invariance law of surrogate dimension reduction for measurement error regression that was established by Li and Yin (2007 Li , B. , Yin , X. ( 2007 ). On surrogate dimension reduction for measurement error regression: an invariance law . Ann. Statist. 35 : 2143 – 2172 . [Google Scholar]).     

Modeling of covariance structures of random effects and random errors in linear mixed models

Abstract

In this paper, we discuss how to model the mean and covariancestructures in linear mixed models (LMMs) simultaneously. We propose a data-driven method to modelcovariance structures of the random effects and random errors in the LMMs. Parameter estimation in the mean and covariances is considered by using EM algorithm, and standard errors of the parameter estimates are calculated through Louis’ (1982 Louis, T.A. (1982). Finding observed information using the EM algorithm. J. Royal Stat. Soc. B 44:98–130. [Google Scholar]) information principle. Kenward’s (1987 Kenward, M.G. (1987). A method for comparing profiles of repeated measurements. Appl. Stat. 36:296–308.[Crossref], [Web of Science ®] , [Google Scholar]) cattle data sets are analyzed for illustration,and comparison to the literature work is made through simulation studies. Our numerical analysis confirms the superiority of the proposed method to existing approaches in terms of Akaike information criterion.     

基于双层规划的反恐应急设施选址模型及算法

恐怖袭击常以人流密集地区的平民作为袭击目标，并存在突发性和随机性等特点，极易造成严重的袭击后果。通过反恐应急设施的合理布局可以缩短救援人员和物资的到达时间，从而减轻袭击后果。首先，对反恐应急设施选址问题进行描述，并将其构造为一类离散双层规划模型。其中，上层规划是关于政府选址的0-1规划问题，下层规划则是关于恐怖分子袭击目标选择的0-1规划问题。其次，结合模型和问题的特征设计算法，利用分支定界算法实现上层选址变量的隐枚举，同时通过下层问题的求解来确定上下界并判断是否满足分枝或剪枝的条件。最后，结合南疆地区的交通拓扑网络进行算例分析，结果证明有效的选址方案可以大大降低袭击损失。     

Exploring the roles of government involvement and institutional environments in the internationalization of Chinese Internet companies

The interactions between government, institutions, and Internet companies have gained attention in the research on the globalization of China’s Internet. However, few studies have been conducted at the company level, and the knowledge about the roles of government and institutions remains limited. Drawing on institutional theory, this empirical study explored the roles and mechanisms of government involvement and the institutional environment in the internationalization of Chinese Internet companies. The results indicated that government involvement could improve these companies’ degree of international breadth through both state ownership and governmental affiliation. However, the results showed that state ownership had a restraining function on their degree of international depth. In the context of institutional transition in China, these effects could vary according to whether Internet companies operate in good or poor institutional environments. By revealing these relationships, this study contributes to both the theoretical and the empirical understanding of governmental influence and institutional roots in the globalization of China’s Internet.     

以一流专业"双万计划"为契机,加强基层教学组织内涵建设——以安徽理工大学为例

高校基层教学组织是高校教学管理体系的重要组成部分和加强内涵建设的重要方面,在"双一流"和"双万计划"建设背景下,其工作成效对于加快学校高质量发展具有基础性乃至决定性作用.认清基层教学组织工作开展中存在的问题并采取措施加以解决,通过规范教学活动、深化教研室管理、加强教学改革、提升基层教学组织活力,将基层教学组织建设成为教学研究和教学管理的中心,这对促进基层教学组织内涵建设和提高学校人才培养质量具有重要的作用.     

论王国维的“本色”观——基于王国维对元曲的评价

王国维用“意境”“境界”等概念建构起自己的美学体系。他认为作为抒情文学的词作必须有作者的真情实感蕴藏于内，“真情”是“境界”说的重要组成部分。出于对“真情”的看重，王国维着力于对元剧的研究，从戏剧艺术的角度，他对元剧十分鄙视，但从文辞的角度，他对元剧十分欣赏。王国维称元曲为“活文学”，与元曲作者蕴于其中的“真情”有莫大关系。王国维对元曲的研究基本延续了治词的角度和观点，论曲仍以“真情”为首要标准。不同之处在于，“当行”也是他的“本色”观的组成部分，是其“本色”观比“意境”说在理论范围上更为广阔之处。相比较而言，吴梅的“本色”观亦注重“真情”，对作品的评论，他更多的是从排场角度分析、评价作品。对作品的用字，吴梅亦崇尚自然，同时又有所保留。
