省域经济洼地区域中心城市发展战略研究——以江苏淮安为例

省域经济洼地地区是实现区域协调发展的重要板块和关键区域。以江苏省淮安市为例,从战略角度审视淮安建设成为苏北重要中心城市的意义和基础,并提出淮安在区域经济和流域经济层面上两个维度的发展定位和三个方向的发展路径。通过纵向融入京沪高铁和京杭运河两条复合发展轴,横向建设淮河流域生态经济带,打造苏皖在江北地区的跨界合作示范区等战略,推动淮安苏北重要中心城市的建设和省域经济协调发展格局的形成。     

Stress-strength reliability of exponentiated Fréchet distributions based on Type-II censored data

In this paper, we consider inference of the stress-strength parameter, R, based on two independent Type-II censored samples from exponentiated Fréchet populations with different index parameters. The maximum likelihood and uniformly minimum variance unbiased estimators, exact and asymptotic confidence intervals and hypotheses testing for R are obtained. We conduct a Monte Carlo simulation study to evaluate the performance of these estimators and confidence intervals. Finally, two real data sets are analysed for illustrative purposes.     

Estimation of geodesic tortuosity and constrictivity in stationary random closed sets

We investigate the problem of estimating geodesic tortuosity and constrictivity as two structural characteristics of stationary random closed sets. They are of central importance for the analysis of effective transport properties in porous or composite materials. Loosely speaking, geodesic tortuosity measures the windedness of paths, whereas the notion of constrictivity captures the appearance of bottlenecks resulting from narrow passages within a given materials phase. We first provide mathematically precise definitions of these quantities and introduce appropriate estimators. Then, we show strong consistency of these estimators for unboundedly growing sampling windows. In order to apply our estimators to real data sets, the extent of edge effects needs to be controlled. This is illustrated using a model for a multiphase material that is incorporated in solid oxide fuel cells.     

A general central limit theorem and a subsampling variance estimator for α‐mixing point processes

We establish a central limit theorem for multivariate summary statistics of nonstationary α‐mixing spatial point processes and a subsampling estimator of the covariance matrix of such statistics. The central limit theorem is crucial for establishing asymptotic properties of estimators in statistics for spatial point processes. The covariance matrix subsampling estimator is flexible and model free. It is needed, for example, to construct confidence intervals and ellipsoids based on asymptotic normality of estimators. We also provide a simulation study investigating an application of our results to estimating functions.

《麦田里的守望者》中的叙事策略和“反英雄”形象

《麦田里的守望者》是美国小说家塞林格（Jerome David Salinger）发表于1951年的长篇小说,也是他最负盛名的小说之一。本文从视点及叙述者的可靠性问题出发,探讨了《麦田里的守望者》中独特的叙事策略所产生的修辞效果。同时以分析小说中“反英雄”形象的塑造为切入点,展示出资本主义消费型社会对人性的异化和解构,从而引发读者对现代人生存困境的深刻反思。     

虚拟社会与道德构建

随着网络的普及 ,虚拟社会中人们的思想、行为、生存方式都发生了新的变化。虚拟社会具有虚拟性、自由性、开放性、非人性化的特点 ;虚拟社会的自由和民主精神、权利意识和平等意识、自主精神、奉献精神、开放思想为道德建设提供了新的生长点 ,但同时带来了一系列负效应。因此 ,道德建设要采取一系列相应的措施 ,以构造文明虚拟社会

简论社会心理学的知识体系

文章通过对多种社会心理学教材的研究,认为社会心理学的基本知识应包括个体社会心理(社会化、自我意识、社会认知、社会动机、社会态度),人际互动(人际沟通、人际关系、合作与竞争、侵犯与利他),社会影响(社会助长、社会惰化、从众与服从)和群体心理(群体规范、群体压力、群体凝聚力、群体首领、群体决策、群体人格)四个方面;认为必须研究和发现这些知识之间的内在联系,从而构建严密的体系;主张以社会化作为社会心理学的逻辑起点。     

“诗意地栖居”：生态女性主义批评视角下的《雪花秘扇》

从生态女性主义批评视角对邝丽莎的小说《雪花秘扇》进行分析与解读。首先对《雪花秘扇》和生态女性主义进行了简单介绍;然后,从女性与自然和谐相处、父权制社会对女性与自然的迫害、女性与自然对父权制社会的解构和邝丽莎和谐生态观与诗意地栖居等四方面进行分析,进一步阐述了作者关于实现男性与女性平等相处,社会与自然和谐发展的“诗意地栖居”的美好境界。
