“沧浪之水”今何在?——文化生态系统视域下的文化生成、传播与实证研究

文化生态系统是特定文化生成、发展和传播的基础.文化内在的“生成性”特征决定了文化生成、发展和传播的基本规律.文化是特定“时间-历史”情境中的主体不断建构的结果,建构形成的“文化”又在新的“时间-历史”情境中得到继承、诠释和传播.纵观以“沧浪之水”为载体、以“有道则出、无道则隐”为核心的“沧浪文化”生成、发展和传播全过程, “沧浪文化”从文化的原始生长点出发,早期为扩展扩散,后期为迁移扩散;经由地理表征“升华”到经典文化中,又从经典文化“落实”到地理表征上的双向互动的生成和反身建构过程.就现实意义而言,不同地域的同类文化之间并非互相排斥而是互相联系、互相支持的关系,绝大多数地理性的“文化正宗”之争可以就此打住.     

Estimation of Deprivation Level Functions using a Numerical Rating Scale

Evaluating and quantifying human suffering in humanitarian operations offers an innovative and potentially powerful way to assess the performance of humanitarian logistics (HL) and help build optimization models. Previous studies have suggested deprivation cost as a metric and have estimated deprivation cost functions for water using willingness‐to‐pay. Our study proposes deprivation levels, defined as the degree of human suffering caused by lack of access to a good or service, and estimates deprivation level functions using a numerical rating scale. Analyzing data collected from respondents with and without disaster experience, we find that individuals in the latter category estimate deprivation differently from the beneficiaries of disaster relief. Our study demonstrates that deprivation levels can be expressed as logistic growth functions with a typical S‐shape, and that these can be integrated into HL optimization models to better account for human suffering.     

A lower bound for the adaptive two-echelon capacitated vehicle routing problem

Adaptive two-echelon capacitated vehicle routing problem (A2E-CVRP) proposed in this paper is a variant of the classical 2E-CVRP. Comparing to 2E-CVRP, A2E-CVRP has multiple depots and allows the vehicles to serve customers directly from the depots. Hence, it has more efficient solution and adapt to real-world environment. This paper gives a mathematical formulation for A2E-CVRP and derives a lower bound for it. The lower bound is used for deriving an upper bound subsequently, which is also an approximate solution of A2E-CVRP. Computational results on benchmark instances show that the A2E-CVRP outperforms the classical 2E-CVRP in the costs of routes.     

我国户口迁移制度弊端与改革刍议

随着社会的发展,户口迁移制度的弊端日益显现,具体表现为：制约了经济统筹协调发展;严重妨害了人力资源的优化配置;延缓了城市化进程;导致产生腐败;影响了社会公正等。当前,改革户口迁移的经济条件和政策条件已经具备,改革的总体思路是：新建、发展新城市群和小城镇,就地、就近转化农业人口为城市居民;采取经济、市场等多种有效措施引导人口合理有序流动;按照因地制宜、循序渐进原则逐步放宽户口迁移限制等。     

执政党建设理论的创立与发展

内容提要改革开放以来,党的执政党理论逐步完善,包括邓小平党建理论、江泽民建党思想以及党的十六大以来党的建设理论三个重要部分。这一理论紧密结合中国特色社会主义实践,借鉴世界其他国家执政党建设经验。以改革创新精神不断推进执政党建设理论的进一步发展。     

父职参与水平:夫妻配对资料的共识和歧见

鉴于国内目前尚未见到使用夫妻配对资料比较双方一致性的方法,本研究使用上海城乡860对夫妻配对样本资料,采用一致百分比和Kappa值,在排除了恰巧一致的偶然性因素后,考察两性对父职参与评价的共识与歧见,不仅归纳出夫妻共识度较高事项的基本特征,同时还通过统计检验,探寻不一致配对数据中存在的性别取向或类似模式,并分析了夫妻认同不一致背后潜在的文化规范、社会暗示、个体需求和期望以及测量误差等原因.     

河南开放型经济发展阶段跨越的理性思考

河南开放型经济发展目前还处于规模扩张阶段的前期,因此,河南不能再沿袭沿海地区的发展阶段推进模式,应直接由规模扩张前期,向以延长现代制造业的产业链并进一步拥有现代制造业核心技术为产业特征的产业升级阶段跨越.     

地方立法听证探析

立法听证是一种重要的民主立法形式.我国把立法听证纳入地方立法程序,于促进我国的民主化进程具有非常重要的意义.但由于地方立法听证制度在我国实践的时间短,存在着许多不足.这就严重影响了我国地方立法听证的发展,进而影响着地方立法的民主化.针对其存在的问题,本文提出了相关制度建议.     

Conditional variance estimation in heteroscedastic regression models

First, we propose a new method for estimating the conditional variance in heteroscedasticity regression models. For heavy tailed innovations, this method is in general more efficient than either of the local linear and local likelihood estimators. Secondly, we apply a variance reduction technique to improve the inference for the conditional variance. The proposed methods are investigated through their asymptotic distributions and numerical performances.     

保护和开发青海农村文化资源探析——以湟中县鲁沙尔镇的民间手工制造业为例

青海著名旅游胜地塔尔寺所在地湟中县鲁沙尔地区拥有源远流长、多民族融合、色彩斑斓的民间手工制造业文化资源。通过对湟中县鲁沙尔镇的民俗文化资源考察发现,由于多种原因,一些民间手工制造业文化资源尚未得到保护和开发。因此,利用农村文化资源发展文化产业,一定要处理好农村文化资源的保护和发展特色文化产业的关系,才能实现民俗文化与文化产业的双赢。
