The Structure of Legal Relations in Online Transactions*

As the civil law expression of internet plus transactions, the legal relations in online trading platform transactions constitute a complex aggregate of legal relationships composed of groups of legal relations. Specifically, they consist of three basic interlinked legal relationships: Contract relations for online trading platform services between the platform provider and the seller or service provider, and between the platform provider and the consumer. This includes the sales or service contract relations between the triad of the seller, the service provider and the consumer. These relations contain five kinds of major content, viz., the provision of transaction space, the publishing of transaction information, price escrow payment, distribution and delivery of the commodity, and transaction credit evaluation. They involve three forms of supplementary legal relations: the supplementary contract relationship between the platform provider and a third party payment institution; between the seller and third party credit reporting agency; and between the seller and a logistics enterprise. The three forms of supplementary contractual legal relations are set up to act on the major contents of the basic legal relationships in online transactions. On the basis of the online trading platform service contract relationships between the platform provider and the triad of the seller, the service provider and the consumer, the flow of the above- mentioned legal relations centers on the contract of sales or service set up between the seller, the service provider and the consumer to accomplish the aim of the online transaction, meet social needs and boost economic development.     

独立学院文化现状及改进对策

大学文化是大学所有成员在历史时间内创造的精神财富和物质财富的总和。而独立学院文化的现状是文化不够鲜明、完整、深厚,因此,独立学院需要从文化培育、文化落实、文化传承、文化创新等方面加以改进。     

Uniformly strong consistency and Berry-Esseen bound of frequency polygons for α-mixing samples

In this article, the frequency polygon investigated by Scott is studied as a nonparametric estimator for α-mixing samples. By some known exponent and moment inequalities, we obtain the uniformly strong consistency and Berry-Esseen bound of the estimator. The present results relax the relevant conditions used by Carbon et al. Furthermore, the convergence rate of the uniformly asymptotic normality is derived, which is O(n^{? 1/11}) under the given conditions.     

浅谈笑话语言的修辞方式与修辞效果

笑话,顾名思义,是一种通过幽默的文字或图示来达到令人会心一笑或捧腹大笑效果的文学形式。而这种通俗的文学形式主要是借助各种修辞手段来呈现。研究笑话中的修辞格,有助于我们更好地有意识地把修辞格运用到笑话幽默的创作当中,从而为人们提供更丰富的精神娱乐。     

基于超总体模型的设计效应分解

本文基于超总体模型研究抽样调查中设计效应的计算问题。首先以随机效应模型为基础，明确了简单随机、二阶段、不等概率和分层抽样对应的超总体模型，进而通过所给模型推导出分层、类集、加权单因素设计效应的计算公式和多因素组合的设计效应计算公式并给出了对应估计量，公式表明：多因素同时存在的组合设计效应等于对应单因素设计效应的乘积。最后，对设计效应的理论值、估计值和真实值之间的关系进行了蒙特卡洛仿真，并利用相对偏倚、相对均方误进行了评价。本文的研究，对复杂抽样设计中正确计算、使用设计效应具有指导意义。

国际商事仲裁裁决效力考辨

关于“国际性”与“商事”内涵的界定，已呈现出由国内标准向国际标准演进的趋势。此种趋势一方面导致了二者解释的逐步扩大，另一方面也促成各国对二者内涵的趋同认识。相比较而言，“裁决”内涵的界定受国内法影响较多，但仍应以“解决了纠纷”作为“裁决”的基本构成要件。建构在以上三个基本概念基础之上的国际商事仲裁裁决的效力，则主要是指裁决对当事人、各相关仲裁庭和法院所产生的保护力、拘束力和执行力，     

An omnibus lack of fit test in logistic regression with sparse data

The usefulness of logistic regression depends to a great extent on the correct specification of the relation between a binary response and characteristics of the unit on which the response is recoded. Currently used methods for testing for misspecification (lack of fit) of a proposed logistic regression model do not perform well when a data set contains almost as many distinct covariate vectors as experimental units, a condition referred to as sparsity. A new algorithm for grouping sparse data to create pseudo replicates and using them to test for lack of fit is developed. A simulation study illustrates settings in which the new test is superior to existing ones. Analysis of a dataset consisting of the ages of menarche of Warsaw girls is also used to compare the new and existing lack of fit tests.     

徐家围子断陷油气运移体系及成藏模式分析

在对含油气组合特征和成藏要素配置关系综合分析基础上，根据断陷盆地发育特征以及天然气藏形成的主控因素，重点分析了地震泵对油气纵向运移的影响，建立了该区油气藏成藏模式，本区发育的油气藏类型主要有构造气藏，岩性气藏和由构造、岩性二者共同控制作用的构造—岩性气藏、地层超覆油气藏以及基岩风化壳油气藏。徐家围子断陷两期构造运动进而形成了正反转构造，为油气提供了良好的构造圈闭及纵向疏导通道。沙河子组共经历了3 次生排烃高峰，第一次由于强烈的构造活动，没有聚集成藏，后两次在其他成藏要素的配合下，最终得以聚集成藏。
