A simple two-step procedure using the Fellegi–Sunter model for frequency-based record linkage

The widely used Fellegi–Sunter model for probabilistic record linkage does not leverage information contained in field values and consequently leads to identical classification of match status regardless of whether records agree on rare or common values. Since agreement on rare values is less likely to occur by chance than agreement on common values, records agreeing on rare values are more likely to be matches. Existing frequency-based methods typically rely on knowledge of error probabilities associated with field values and frequencies of agreed field values among matches, often derived using prior studies or training data. When such information is unavailable, applications of these methods are challenging. In this paper, we propose a simple two-step procedure for frequency-based matching using the Fellegi–Sunter framework to overcome these challenges. Matching weights are adjusted based on frequency distributions of the agreed field values among matches and non-matches, estimated by the Fellegi–Sunter model without relying on prior studies or training data. Through a real-world application and simulation, our method is found to produce comparable or better performance than the unadjusted method. Furthermore, frequency-based matching provides greater improvement in matching accuracy when using poorly discriminating fields with diminished benefit as the discriminating power of matching fields increases.     

论近代法国民族主义运动的蜕变——从"左翼"民族主义到"右翼"民族主义

西方学者普遍认为,近代法国民族主义在19世纪后半叶经历了一次"右转弯",即从"左翼"民族主义向"右翼"民族主义过渡。事实上,这种过渡不在于"左翼"民族主义的急流勇退和"右翼"民族主义的狂飙突进,而在于"左"、"右"两翼先后垄断民族主义话语。在这一蜕变过程中,"左"、"右"两翼都保留了各自的民族主义传统,并于第一次世界大战前夕实现了"神圣联合"。

The moderating effect of foreign direct investment intensity on local firms' intangible resources investment and performance implications: A case from China

Foreign direct investment (FDI) has been known to generate positive externalities to increase the productivity and competitiveness of domestic industries through knowledge and technology spillover. This study focuses on the indirect effect of FDI by investigating whether FDI intensity benefits local firms by enhancing the local intellectual property rights (IPR) environment. We argue that due to the inadequate IPR environment in emerging economies, local firms' intangible resources investment can be negatively related to firm performance. Further, we suggest that FDI intensity can improve the local IPR environment, thereby enhancing the appropriability of local firms' intangible resources investment. We find empirical evidence to support our arguments by examining 70 semiconductor firms in China from 1999 to 2006, and we discuss the theoretical and practical implications of the impact of FDI intensity on the local IPR environment.     

社会文化变迁与民族心理

科学的进步所引起的并不仅仅是一场生产革命或经济革命,而是整个社会以及人们生活方式和价值观念的急剧变革。在这种全世界范围内的现代化进程中,我们要剔除各民族文化的糟粕,有所选择地继承世界各民族的优秀文化,从而推进民族心理和文化的现代化发展。     

论严复对中国传统道德的改铸

严复对中国传统道德的改铸主要表现在义利关系、群己关系、自由责任关系、权利义务关系、善恶标准等方面。严复对中国传统道德的改铸,具有两大特点:鲜明的资本主义伦理色彩和较强烈的后现代主义价值诉求;具有两大作用:改造、更新着中国传统道德的内容、价值和提示着当今道德建设的方式和方向。     

文化产业竞争力影响就业水平的FDI效应研究

本文通过构建交易成本信号传递模型及FD I就业效应模型,并运用面板数据联立方程计量方法,定量研究了文化产业竞争力影响就业水平的FD I效应机理及其与直接效应的比较。研究发现:文化产业竞争力越强的地区,其通过吸收FD I进而促进就业的效应就越大,反之则越小;文化产业发展促进就业的FD I效应大于其直接效应。基于研究结论,最后就如何提高我国的文化产业竞争力进而促进就业水平提出了相应的政策建议。     

普列汉诺夫的史学方法论及其评价

普列汉诺夫的史学方法论坚持了唯物史观从社会存在说明社会意识,从经济状况寻找决定历史发展的根本原因,从经济、政治、文化、宗教、道德等历史因素的相互作用阐述历史过程等基本原理.特别是提倡将哲学方法作为历史研究的基本方法看待,把促进唯物史观理论发展作为历史研究的任务加以强调,为发展唯物史观史学方法论做出了贡献.但将相互作用理解为折衷主义则体现了其局限性.     

论期刊社与作者的权利冲突——对著作权法第33条、第34条的反思

我国著作权法第33条、第34条把期刊社的权利确定为两项,其一为审稿权,其二为修改权。在实践中,这两项权利通常表现为期刊社的审稿权与作者发表权的冲突、期刊社修改权与作者许可修改权及保护作品完整性权的冲突、期刊社声明的专有出版与作者法定的转载、摘编权之冲突。第33条、第34条在平衡这些冲突时有所偏颇或界限模糊,容易引起争议。
