统筹城乡经济社会发展新模式的绩效与不足——以厦门市同安区“金包银”工程为例

厦门市“金包银”工程在促进工业化、农村就地城市化的同时，还在一定程度上确保了农民失地不失业、不失收，实不失为统筹城乡经济社会发展的一种新模式。但尚处于探索之中的新模式仍不可避免在“银里”改造、“金边”管理、园区内配套的教育设施、服务设施规划布局等方面留下“后遗症”。为此，要有针对性地通过加快工业集中区内公共配套设施建设、创新管理机制、加大政策扶持力度等有效途径予以完善，最大限度地增扩该模式的绩效。     

工程项目建设和运营阶段有限理性的应对

工程项目的建设和运营阶段在整个项目周期中占重要地位,而决策者有限理性行为导致项目初期目标在这两阶段发生偏差。分析了有限理性在项目建设、运营阶段的表现之后,提出可以通过项目中的知识管理和信息的事后补充两种方法来应对建设和运营阶段的有限理性,并分别构建了两种方法所对应的模型,希望对工程项目管理具有一定的理论及实际意义。

Supporting the allocation of software development work in distributed teams with multi-criteria decision analysis

In the fast moving software industry, projects have been increasingly developed by distributed teams, which are located in geographically remote offices and collaborate using information communication technologies. In such environments, project distribution presents specific challenges, as work in distributed teams increases project technical complexity, communication lines multiply and stakeholders’ interests may be divergent. Despite the importance and complexity of this type of problem, it seems that there is a lack of reports, in the literature, of systems that could support these decisions. This paper presents a real-world case study, where we developed a multi-criteria model for supporting the distributed team work allocation decision for a major global software company. It was developed with a group of software development project managers, using decision conferencing and multi-attribute value analysis. The model deals not only with software engineering attributes, but also “soft” and strategic issues, like team satisfaction and training opportunities. We also discuss some issues and challenges faced during this modelling process.     

基于关键链的项目工期风险断链式控制研究

以关键链为物质载体的风险效应的传递在外界环境的作用下，具有一定的扩增性。本文在关键链的基础上，从风险效应链式形态出发，通过对项目工期风险链式传递机理的分析，识别项目关键链上的关键工期风险结点，针对性的将关键链管理中的项目缓冲分解到关键结点之后，有效抑制其关键结点的传递途径，从而达到断链的效果，减少破坏的扩增性，达到风险控制的目的，从而提高项目管理的效率。     

项目经理的领导力要素分析

项目经理作为项目团队的领导者,就要具备很高的能力和素质才能带领好整个团队。本文重点对项目经理的领导力进行研究,全面分析领导力的内在要求和外在表现,并基于分析提出领导力模型和评价要素,为项目经理的领导力研究提供了一种新的思维方法。     

我国知名大学校长个人特征研究

对34位知名大学校长个人特征研究发现:33位为男性而只有1位女性,他们主要来自东部和中部发达地区,94.11%在40~59岁时成为大学掌舵人,91.17%具备研究生学历,94.11%理工科专业出身,61.76%有国外大学学习的经历,50%至少有一个本校的学位,50%是中国科学院或中国工程院士,平均任职年限为4.6年,这些特征表现出与国外知名大学校长特征的差异性,并对知名大学校长的涌现和更好成长以及知名大学的发展有一定启示。

Environmental Exposures to Metals in Native Communities and Implications for Child Development: Basis for the Navajo Birth Cohort Study

Two disparate statistics often cited for the Western United States raise concern about risks for developmental disabilities in Native American children. First, 13 of the states with the highest percentage of Native American population are located in the Western United States (U.S. Census Bureau, 2012 U.S. Census Bureau. (2012). The American Indian and Alaska Native Population: 2010 (U.S. Census Briefs, January, #C2010BR-10). Retrieved from http://www.census.gov/prod/cen2010/briefs/c2010br-10.pdf [Google Scholar]). Second, more than 161,000 abandoned hard-rock mines are located in 12 Western states (General Accounting Office, 2014 General Accounting Office. (2014, July 14). GAO-11–834T: Abandoned Mines. Information on the number of hardrock mines, cost of cleanup, and value of financial assurances. Statement of Anu K. Mittal, Director, Natural Resources and Environment Team, Testimony before the Subcommittee on Energy and Mineral Resources, Committee on Natural Resources, House of Representatives. Retrieved from http://www.gao.gov/products/GAO-11-834T [Google Scholar]). Moreover, numerous studies have linked low-level metals exposure with birth defects and developmental delays. Concern has emerged among tribal populations that metals exposure from abandoned mines might threaten development of future generations.
