现代经济条件下企业统计信息化建设的实现途径

在社会主义市场经济环境中，企业统计信息是企业信息的主体，企业统计位居企业信息的中心地位，贯穿于企业经营管理的全过程。依据我国企业统计不能适应现代企业发展的客观现实并通过对我国企业统计信息化发展的研究分析，提出企业统计信息化建设的基本条件和现代企业统计信息化建设的实现途径。     

基于文献计量的中文科技新词探讨

文章以中国知网的中文学术文献数据库为基础,利用词频统计,结合时间参数,对中文科技新词做了探讨。文章认为,高被引论文的关键词包含了专业领域的重要中文科技名词。统计结果表明,大部分高被引论文为基金论文。由于基金论文在全部论文中所占比例较低,因此,不需要考虑全部新论文,只要对其中基金论文的关键词做词频统计,就有助于发现大部分重要中文科技新词。这样,既减少了工作量,也减少了盲目性。此项工作对科研工作者和术语工作者有一定帮助。     

Maxwell's color statistics: From reduction of visible errors to reduction to invisible molecules

This paper presents a cross-disciplinary and multi-disciplinary account of Maxwell's introduction of statistical models of molecules for the composition of gases. The account focuses on Maxwell's deployment of statistical models of data in his contemporaneous color researches as established in Cambridge mathematical physics, especially by Maxwell's seniors and mentors. The paper also argues that the cross-disciplinary, or cross-domain, transfer of resources from the natural and social sciences took place in both directions and relied on the complex intra-disciplinary, or intra-domain, dynamics of Maxwell's researches in natural sciences, in color theory, physical astronomy, electromagnetism and dynamical theory of gases, as well as involving a variety of types of communicating and mediating media, from material objects to concepts, techniques and institutions.     

Can the behavioral sciences self-correct? A social epistemic study

Advocates of the self-corrective thesis argue that scientific method will refute false theories and find closer approximations to the truth in the long run. I discuss a contemporary interpretation of this thesis in terms of frequentist statistics in the context of the behavioral sciences. First, I identify experimental replications and systematic aggregation of evidence (meta-analysis) as the self-corrective mechanism. Then, I present a computer simulation study of scientific communities that implement this mechanism to argue that frequentist statistics may converge upon a correct estimate or not depending on the social structure of the community that uses it. Based on this study, I argue that methodological explanations of the “replicability crisis” in psychology are limited and propose an alternative explanation in terms of biases. Finally, I conclude suggesting that scientific self-correction should be understood as an interaction effect between inference methods and social structures.

用数理统计方法建立钢的淬透性曲线模型

利用统计学中的Ｌｏｇｉｓｔｉｃ数理模型，经过适当改造后可以建立起主要钢种的淬透性曲线的数学模型，并且具有较同的拟合性，误差较小，结合此种方法，通过少量的实测点就可以作出一般钢种的淬透性曲线。此种方法在实践上对于机械零件热处理的自动化，在理论上对探索钢的物理冶金机理，可能具有较大的意义。
