A new confidence interval in measurement error model with the reliability ratio known

For the slope parameter of the measurement error model with the reliability ratio known, this article constructs a fiducial generalized confidence interval (FGCI) which is proved to have correct asymptotic coverage. Simulation results demonstrate that the FGCI often outperforms the existing intervals in terms of empirical coverage probability, average interval length, and false parameter coverage rate. Two examples are also provided to illustrate our approach.     

中外网络环境下著作权限制制度的比较及启示

网络技术的应用带来了著作权人权利范围的扩张,从而破坏了权利人与公众之间的利益平衡,激化了权利人与使用者的矛盾。目前,我国还没有关于网络环境下著作权权利限制方面的明确立法,而网络环境下著作权的纠纷却层出不穷,给司法实践中的具体操作带来了困难。通过对国外相关的立法经验和国际条约的规定进行分析和比较,可得出有益的启示,应从权能限制即合理使用和法定许可这两个方面来构建我国网络环境下著作权的权利限制。     

专业化交易组织成长与区域经济发展--再论农村市场经济发展的"义乌模式"

义乌区域经济发展的动因不是工业化,而是市场化;商人的集体行动与政府的开明决策,使义乌成为全国最大的小商品流通中心;"义乌模式"的优势,在于交易方式的专业化,小商品市场的专业化交易形成了信息规模经济、外部规模经济和范围经济,从而确立了义乌小商品的低成本优势;尔后,市场秩序扩展、专业化交换组织成长与产业集聚发展的良性互动,形成了义乌独特的工业化、城市化路径.     

略论闽语研究的“西进”

闽语通行地域跨越多个省份及海外华人社区,人口大约不会少于7000万人。闽语研究历史悠久,成果丰硕。研究面日益扩大,研究内容日益深化。然而,以往的闽语研究,仍存在着研究布局不够平衡的问题。研究的范围多集中在闽南、闽东这两支上,以福建的厦、漳、泉闽南话及粤东属闽南方言系统的潮汕话,和以福州话为代表的闽东闽语成果较为可观。而相对忽略了对边远的、分散的闽语方言点的调查。为此,文章认为闽语研究应尽可能扩大调查的覆盖面,提出多把眼光射向那些分布在闽语大本营闽、台以西的海南岛、粤西南以及广西境内的闽语通行地区,是为“西进”。     

边限检验理论及几点讨论

检验经济变量之间长期关系的协整技术要求变量是同阶单整的,这不可避免地涉及一定程度的预检验问题,而预检验问题会增加变量间长期关系分析的不确定性。当不能确定变量的单整类型时,边限检验理论提出了一个可以直接检验一个变量和一组解释变量之间长期关系的新方法。在介绍了边限检验方法中基本的VAR模型和假设及边限检验方法中用到的重要统计量——Wald统计量和T统计量及它们各自的渐近分布形式后,说明了边限检验理论在理论和实际运用当中需要注意的几个问题,最后通过实例分析说明了边限检验理论的运用。     

西方国家意识形态扩张的现代性路径及应对方略

生态、潮流、反恐、普世等问题已异化为西方意识形态扩张的现代性路径;从全球化趋势的形成和发展、主流意识形态建设的弱化、新媒体发展和普及等方面着力分析西方意识形态扩张现代性路径的诸多原因,加强马克思主义意识形态宣传教育、提升马克思主义意识形态交往的主动权和影响力、促进社会发展和惠民建设等进行应对。     

品牌拓展新市场过程中消费者选择行为研究

研究消费者品牌选择行为是进行品牌拓展新市场的前提。本文基于消费者决策理论,利用元胞自动机分析了品牌文化、广告宣传、邻居关系及数量、竞争者、市场的经济环境等对消费者进行品牌选择时的影响,研究结果表明该模型能较好地模拟出品牌进行拓展新市场过程中的消费者选择行为。通过对品牌拓展新市场过程中的消费者选择行为的分析,找出更适合进行品牌扩张的区域。     

Asymptotic non-null distribution of a test of equality of exponential populations

In this paper further asymptotic expansions of the non-null distribution of the likelihood ratio criterion for testing the equality of several one parameter exponential distributions are obtained when the alternatives are close to the hypothesis. These expansions are obtained for the first time in terms of beta distributions.     

Surveillance of the interaction parameter of the ising model

Surveillance to detect changes of spatial patterns is of interest in many areas such as environmental control and regional analysis. Here the interaction parameter of the Ising model, is considered. A minimal sufficient statistic and its asymptotic distribution are used. It is demonstrated that the convergence to normal, distribution is rapid. The main result is that when the lattice is large, all approximations are better in several respects. It is shown that, for large lattice sizes, earlier results on surveillance of a normally distributed random variable can be used in cases of most interest. The expected delay of alarm at a fixed level of false alarm probability is examined for some examples.     

A powerful test for uniformity to detect highly peaked alternativedensities

A new class of statistical tests for uniformity based on sample ranges is proposed to detect a uniform density contaminated by a density with one or more high peaks. These kinds of alternatives occur quite frequently, especially in physics. It is shown that the proposed tests arc consistent and have high Pitman asymptotic relative efficiencies. Results of a Monte Carlo power study indicate that they, compared with other tests of uniformity, possess good power properties.A comparative study of various tests is also conducted using real data. An effcient algorithm for computing out test statistic and a table of percentage points are given, providing a practical guide for using the new test.
