路径与旨趣：近代浙江文化史研究嬗变

近代江南史研究见证并参与了近代中国社会文化的变迁,相比上海、苏南等地,浙江近代文化史研究亟需进一步拓展与深化。以革命与事件、结构与认同、学人与学派等研究路径为线索,回顾浙江近代文化史研究的关键要素,应能展望今后研究的方向：去意识形态化、突破单向度思维,以多元视角阐释近代浙江的革命群体与事件;揭示近代浙江文化现象背后深层次的社会关系和权力关系、结构与心态、集体记忆与文化认同,进一步认知近代精英与民众、国家与社会的能动关系;浙江学人在近代学术流变中发挥承前启后的作用,学人学术思想的本意及其实践成为近代浙学重建的重要参考。运用整体视角综合事件、结构、学理,积极拓展史料与理论范式,深入发掘近代浙江文化的历史经验和内在脉络,将为探索中国原理提供有效的知识与思想资源。     

基于伯克认同理论的品牌命名研究

有利砂体识别与解释

天然气的产量与砂岩的厚度,孔隙度,连通性,砂泥比等有密切的关系。为了解决砂体在空间以什么形态出现,其方向如何,纵向上如何变化,连通形式如何等问题,在前人研究的基础上,对篷来镇组某工区的砂体进行了精细识别和解释。在地震剖面上,砂体的响应一般表现为强振幅,低频率。孔隙性好,含气丰度高的砂体往往表现为速度低和极性反转的特点。但发现该工区的砂体在地震剖面上表现形式多变,甚至出现了合成地震记录与井旁地震记录严重不吻合的现象,故砂体识别工作不能遵循统一模式。因此,采用了多井约束,多层标定,分层解释来识别有利砂体。     

Dealing with the Initial Observation in the LM Unit Root Test

This article proposes a linearly weighted unit root test with a new weighting scheme which reflects the trade-off in power between the ADF and LM tests regarding the initial value of a time series. Simulation results indicate that the proposed test has better power performance and works better than other available tests in the literature for a range of initial conditions.     

Pooled Panel Unit Root Tests and the Effect of Past Initialization

This paper analyzes the role of initialization when testing for a unit root in panel data, an issue that has received surprisingly little attention in the literature. In fact, most studies assume that the initial value is either zero or bounded. As a response to this, the current paper considers a model in which the initialization is in the past, which is shown to have several distinctive features that makes it attractive, even in comparison to the common time series practice of making the initial value a draw from its unconditional distribution under the stationary alternative. The results have implications not only for theory, but also for applied work. In particular, and in contrast to the time series case, in panels the effect of the initialization need not be negative but can actually lead to improved test performance.     

The Local Power of the CADF and CIPS Panel Unit Root Tests

Very little is known about the local power of second generation panel unit root tests that are robust to cross-section dependence. This article derives the local asymptotic power functions of the cross-section argumented Dickey–Fuller Cross-section Augmented Dickey-Fuller (CADF) and CIPS tests of Pesaran (2007), which are among the most popular tests around.     

信任对农民创业机会识别的影响

基于信任视角,构建农民创业者信任对创业机会识别的理论分析框架,运用链式多重中介方法,对浙江、安徽、河南和陕西4省880份农民创业者访谈数据进行实证分析,结果发现:信任能显著提高农民创业机会识别;农民创业者信任能通过外部知识获取与创业警觉性对创业机会识别产生间接影响,其作用路径有三条:外部知识获取的部分中介作用、创业警觉性的部分中介作用及外部知识获取与创业警觉性的链式中介作用。因此,政府应完善农民创业相关规章与制度;推进农村文化建设,提高信任水平;增加农民创业知识与技能的供给,培养农民创业者的机会警觉性。     

农民合作社信用合作满意度实证研究——基于内部社会资本分析视角

基于对3个省的3个县市区253家合作社的调查数据,运用因子分析法和二元Logistic分析法实证研究合作社社员满意度的影响因素。因子分析结果表明:内部社会资本由内部信任、内部规范和社会网络等3个因子构成。Logistic回归分析结果显示:内部信任、内部规范这两个测量变量与社员满意度存在显著的正相关性,而社会规范与社员满意度之间呈显著的负向相关关系。组织认同能够提高社员对合作社的满意度,且加入合作社时间越短的社员对合作社的满意度越高。此外,还通过剔除不显著变量和增加变量的方法对社员满意度进行回归分析,结果证明研究结论具有高度的稳健性。据此提出建立健全信用合作管理制度、加强合作社的社会整合功能、发挥合作社示范作用的政策建议。     

A new heavy-tailed distribution defined on the bounded interval: the logit slash distribution and its application

This paper proposes a new heavy-tailed and alternative slash type distribution on a bounded interval via a relation of a slash random variable with respect to the standard logistic function to model the real data set with skewed and high kurtosis which includes the outlier observation. Some basic statistical properties of the newly defined distribution are studied. We derive the maximum likelihood, least-square, and weighted least-square estimations of its parameters. We assess the performance of the estimators of these estimation methods by the simulation study. Moreover, an application to real data demonstrates that the proposed distribution can provide a better fit than well-known bounded distributions in the literature when the skewed data set with high kurtosis contains the outlier observations.
