关于兽面纹内涵的探讨

关于兽面纹的内涵的探讨,学者主要提出两种意见,一是关于其图案形式所代表的形象的争论,另一方面是关于其蕴含的宗教文化功能的探讨.而根据兽面纹的的载体青铜器的用途和纹样图案特点分析,兽面纹的内涵应具有时代性和多样性的特征.     

专利保护期滥用解析——以跨国公司在中国专利战问题为视角

在日益激烈的高科技竞争背景下,专利权滥用的认定演变为不断更新的全球问题.WTO-TRIPS协议对专利滥用并没有明确认定范围,不同国家的做法不尽相同,而我国的相关立法尚属空白.只有从专利保护期滥用争议在全球范围、国内内外资企业范围、历史范围和我国市场整体利益范围上的主要特点,以及滥用认定中懈怠原则的基本法理层面上,透视滥用专利战的产生与存在现象,我们才可以对全球专利战产生相对客观理性的认识态度.面对全球化的专利战,应当有序提高专利注册标准、合理借鉴西方懈怠制度.通过有组织的强化专利法及其滥用认定规范,才能对专利权人利益予以合法保护,进而维护我国在技术市场开放及技术进出口方面的整体利益.     

International Trade and the Urbanization of Developing Countries: Evidence from Asia

Abstract

A grain surplus and the grain trade are closely related to the urbanization of developing countries. However, existing literature has not given adequate attention to this issue. Our paper develops a theoretical model to explain the mechanisms whereby changes in the grain surplus constrain the level of urbanization in a closed economy context and the grain trade affects the level of urbanization by acting on the grain surplus in an open economy context. A test of the theoretical model applied to some developing countries in Asia during the period 1993-2010 shows that international trade is generally negatively correlated with level of urbanization. However, cereal and non-cereal trade vary in terms of their relation to urbanization: whereas the former is positively correlated with level of urbanization, the latter is negatively correlated with it. Since the net import of cereals relaxes the constraint imposed on the level of urbanization by the domestic grain surplus, it can have a marked positive effect on the course of urbanization. Our research findings show that provided grain production or grain security is guaranteed, developing countries may adopt a policy of importing an appropriate amount of grain to increase their level of urbanization.     

Uniform asymptotics for ruin probability of a two-dimensional dependent renewal risk model

ABSTRACT

In this paper we consider the tail behavior of a two-dimensional dependent renewal risk model with two dependent classes of insurance business, in which the claim sizes are governed by a common renewal counting process, and their inter-arrival times are dependent, identically distributed. For the case that the claim size distribution belongs to the intersection of long-tailed distribution class and dominant variation class, we obtain an asymptotic formula, which holds uniformly for all time in an infinite interval. Moreover, we point out that the formula still holds uniformly for all time in an infinite interval for widely dependent random variables (r.v.s) under some conditions.     

读懂《多余的话》的一些想法

瞿秋白在《多余的话》中通过自我否定、自我丑化,自制了一个负面形象的瞿秋白,目的是要使杨之华厌恶自己,忘却自己.他不愿因自己的死给亲人留下巨大的伤痛.瞿秋白的这一良苦用心也给《多余的话》带来不应有的负面效应.《多余的话》中有真话、反话,也有不少夸大真实的话,读懂《多余的话》,不能望文生义.     

物理化学设计型实验的测量知识准备

物理化学是一门与其他学科交叉渗透的综合性强大学科.从训练学生综合分析解决实际问题的能力、培养创新意识等方面来看,物理化学实验很具有代表性.因此物理化学实验教学改革的方案也比较多,很多很好的设计型或者叫科研型方案被提出.然而开设该设计型实验课之前,学生需要对于传感器、测量、计算机等方面知识做些准备,文章就此提出一些想法和建议.

生态行政学:理论源流、分化及其困顿

由于生态环境的恶化,政府和公民迫切需要行动起来,以应对日益严峻的生存危机.在反思工业文明的过程中,具有后现代情境的生态主义为生态行政理论提供了实践理性的基础.生态政治的核心价值和现实偏向以及行政生态理论的历史发展,均催化着生态行政理论的萌芽.由于概念认定和价值趋向的差异,以及范式转换和治理领域悖论的存在,生态行政研究亦呈现出分化、多元化与发展的困顿.生态行政理论应在整体性与共生性的原则下着力提升治理系统的开放性和必要的多样性,以应对环境领域日益严峻的复杂性与不确定性.     

Statistical evaluation of individual bioequivalence

Drug switchability requires the evidence of individual bioequivalence which -refers to the comparison of the closeness between the two distributions of the pharmacokinetic (PK) responses from the same subject obtained under the repeated administrations of the test and reference formulations. Advantages and drawbacks of the current statistical procedures for assessment of individual bioequivalence are discussed with emphasis on the aggregate-based criteria, An intersection-union test based on disaggregate criteria is proposed for the evaluation of individual bioequivalence. In addition, a modified aggregated criterion is suggested to overcome the drawbacks suffered by aggregate criteria. The relationships among different criteria are examined, and the performance of the procedures will be compared. A numerical example is given to illustrate the proposed procedures.
