基于SAP R/3的信息化设备管理系统的实施

通过对企业设备管理的需求以及设备管理业务流程的分析，开发了基于SAP R/3 PM平台的设备管理信息化系统。通过与其他SAP模块的集成，该系统以维修通知单为我体实现了设备的技术管理，以维修订单为我体实现了设备的经济管理，并实现了相关信息的查询。     

齿轮箱系统特性分析

利用时间序列ARMA模型求出单级齿轮箱系统的传递函数，然后求出系统正常工作、齿轮断齿、轴承滚柱磨损、轴卺守圈和外圈裂纹5种情况下系统稳态和瞬态的Bode图。齿轮箱系统特性只与本身结构有关，5种情况下同种故障的系统稳态和瞬态Boide图图像特征一致，说明可以用它来分析瞬态信号。通过图形比较，可以简单、有效地判断故障状态。

Risk Awareness of Interpersonal Trust and Entrepreneurship in China: Evidence from Survey Data

This paper aims to build a theoretical framework for the influence of risk awareness of interpersonal trust (RAIT) on entrepreneurship, and explores the influence of RAIT on entrepreneurship with the micro survey data from the Chinese General Social Survey (CGSS) 2010–2013. The study found that, individuals with higher level of RAIT, their probability of starting new business will increase significantly, and with every increase of RAIT level, the probability of business venturing increase almost 4.0%. No mediation effects of information screening and cooperative mechanism are found in the relationship between RAIT and entrepreneurship. Moreover, during the venturing process, risks accompanying interpersonal trust cannot be reduced by social input; the reduction occurs only in eastern China where the economic system and the industrial development standards are more comprehensive and mature. This paper contributes to the literatures in the following two areas: it provides new evidence on how to deal with risks in the entrepreneurship process that accompanying interpersonal trust; meanwhile, it provides an explanatory mechanism on how the risk awareness affects business venturing.     

Can Trade Agreements Curtail Trade Creation and Prevent Trade Diversion?

This paper investigates how pre‐existing preferential trade agreements (PTAs) dilute the trade creation effect and shield the trade diversion effect of new PTAs. Countries having pre‐existing PTAs enjoy smaller gains in intra‐bloc trade because of the dilution effect and experience smaller losses or even gains in extra‐bloc trade because of the shielding effect. The findings support the proposition that PTAs could be used to fend off future trade diversion.     

Properties of Census Dual System Population Size Estimators

We study parametric and non‐parametric approaches for assessing the accuracy and coverage of a population census based on dual system surveys. The two parametric approaches being considered are post‐stratification and logistic regression, which have been or will be implemented for the US Census dual system surveys. We show that the parametric model‐based approaches are generally biased unless the model is correctly specified. We then study a local post‐stratification approach based on a non‐parametric kernel estimate of the Census enumeration functions. We illustrate that the non‐parametric approach avoids the risk of model mis‐specification and is consistent under relatively weak conditions. The performances of these estimators are evaluated numerically via simulation studies and an empirical analysis based on the 2000 US Census post‐enumeration survey data.     

高新技术企业间知识治理对协同创新绩效的影响

知识治理是知识管理理论发展的新阶段，在动态复杂的创新环境下，知识治理与创新的关系已成为学术界关注的热点话题。对高新技术企业进行问卷调查，探讨知识治理对协同创新绩效的影响并采用有调节的中介效应模型，分析知识转移和制度环境在其中的作用机制。结果表明，正式知识治理与非正式知识治理均会对知识转移产生正向影响；知识转移在知识治理与协同创新绩效关系中存在完全中介效应，即知识治理对协同创新绩效的正向效应是通过知识转移实现的；制度环境正向调节知识转移对协同创新绩效的影响，即在良好的制度环境下，知识转移的中介作用更强。     

论先秦思想家的环境保护思想

先秦思想家的思想中蕴含着丰富的环境保护思想,"天人合一""仁民爱物""知曰常明""取之有节""圣王之制"等环保观念,设置环境保护机构,制定比较完善的环境保护法律和法规的实践,都对今天的可持续发展具有十分重要的意义,值得我们借鉴。
