我国数据库法律保护探析

随着科技的不断进步和计算机网络的广泛推广,数据库已经成为人们获取信息资源的主要途径之一。我国作为发展中国家,数据库产业仍处于起步阶段,没有明确的法律保护规定。因此,我国应努力加强人们对知识产权保护的认识;结合中国国情,不应对数据库采取特殊有利保护;并要加快数据库的法制建设,以便于创造良好的数据库产业发展的法制环境。     

游志贺岛

暮春,一个日暖风熏的周日,我们游访了志贺岛. 志贺岛在福冈市区北部,一条由东向西凸进大海,环抱博多湾的细长半岛的顶端.从地图上看,志贺岛的形状很像意大利靴子形半岛尖上的西西里岛.不同的是,它是一个由被称作"海中之道"的自然沙道同陆地连在一起的陆连岛.     

基于Toastmasters的外贸实践能力培养研究——以福建农林大学国际经济与贸易2009级为例

Risks Perception of Electromagnetic Fields in Taiwan: The Influence of Psychopathology and the Degree of Sensitivity to Electromagnetic Fields

Little is known about the perceived health risks of electromagnetic fields (EMFs) and factors associated with risk perception in non‐Western countries. Psychological conditions and risk perception have been postulated as factors that facilitate the attribution of health complaints to environmental factors. This study investigated people's perceived risks of EMFs and other environmental sources, as well as the relationships between risk perception, psychopathology, and the degree of self‐reported sensitivity to EMFs. A total of 1,251 adults selected from a nationwide telephone interviewing system database responded to a telephone survey about the relationships between environmental sources and human health. The interview included questions assessing participants’ psychiatric conditions and the presence and degree of sensitivity to EMFs. One hundred and seventy participants were self‐identified as having sensitivity to EMFs, and 141 met the criteria for psychiatric conditions without EMF sensitivity. More than half of the survey respondents considered power lines and mobile phone base stations to affect people's health to a big extent. Higher sensitivity to EMFs, psychopathology, being female, being married, more years of education, and having a catastrophic illness had positive associations with perceived risks of EMF‐related environmental sources as well as for all environmental sources combined. We observed no moderating effect of psychopathology on the association between degree of sensitivity to EMF and risk perception. Thus, psychopathology had influence on general people's risk perception without having influence on the relationship between people's degree of sensitivity to EMF and risk perception. The plausible explanations are discussed in the text.     

Improved likelihood-based inference for the stationary AR(2) model

An improved likelihood-based method based on Fraser et al. (1999) is proposed in this paper to test the significance of the second lag of the stationary AR(2) model. Compared with the test proposed by Fan and Yao (2003) and the signed log-likelihood ratio test, the proposed method has remarkable accuracy. Simulation studies are performed to illustrate the accuracy of the proposed method. Application of the proposed method on historical data is presented to demonstrate the implementation of this method. Furthermore, the method can be extended to the general AR(p) model.
