PERT技术在机电安装工程中的工期——人力资源优化实例

PERT技术的网络计划软件是基于编制工程进度计划要求而开发的一种新兴的工程管理技术软件。但是，目前该网络计划软件在国内应用仍然较少，基本上仅局限于工程投标阶段使用，笔者试图将该技术应用于机电安装工程工期——人力资源优化管理工作中，以企用实例来推广该项技术的广泛应用。     

Q-analytics: An ethics case on unlicensed software usage

This short role-taking ethics case is designed to provide students with several different perspectives related to the unauthorized/unlicensed use of software within a realistic accounting setting. Although the case could be considered for use in a variety of accounting classes at both undergraduate and graduate levelswith limited preparation, it is likely to be most relevant to Accounting Information Systems, Auditing, Controllership, and Accounting Ethics courses. The case can be read in about ten minutes, after which the class is assigned to groups that deliberate over the concerns of six different roles regarding the software-usage issues implied in the case.The issues are relevant to the students because they will inevitably encounter software-usage problems in their personal or professional lives. Furthermore, they inevitably have been exposed to similar copyright-infringement issues in the realms of music and video, which helps make for a rich class discussion.The case has consistently generated considerable discussion and debate within a graduate-level controllership course. A survey of students from five graduate accounting classes over a three-year period indicates favorable perceptions of the case.     

江汉测录井质量管理信息化实践

江汉测录井公司按照"系统管理"的质量管理新理念,建立了基于因特网的B/S架构的QM-600质量管理信息系统。该系统加强了企业质量管理信息交流的"分布性",淡化了"过程控制"信息,多个独立地智能信息集成与发布智能模块,能更好地服务企业的"自组织"。整个系统恰似一个完整的质量管理"数字神经网络",供石油工程企业实现质量管理信息化借鉴。

Foresighting FLOSS (free/libre/open source software) from a developing country perspective: The case of Turkey

Since free/libre open source software (FLOSS) promotes collaboration and contributions from different parties in software production and innovation processes, it can create a unique opportunity for developing countries, by generating an innovative capability in software technology. To benefit from this opportunity, it is important to understand the strategic factors and future trends that affect the development of an efficient FLOSS economy in developing countries.This paper aims to examine the strategic factors and future trends that are likely to affect the development and deployment of FLOSS in Turkey. Based on the internal and external factors identified through the practice of technological foresight, a SWOT analysis will be carried out to identify the strengths, weaknesses, opportunities and threats for Turkey in creating a competitive software industry that can benefit from the advantages of FLOSS. Accordingly, with regard to the required technical infrastructure, an innovative/competitive business climate, skilled human resources and support for institutional structures, policy suggestions are outlined here that could be usefully implemented by government, industry and universities.
