Maximizing strategic value from megaprojects: The influence of information-feed on decision-making by the project manager

Large projects are notorious for erosion of value during execution. Decisions made by project managers have a significant impact on the strategic value of the asset delivered, and those decisions depend on the information feed on which they are based. This study uses theories of organizational behavior, decision-making and program management to investigate the impact of information feed used by project managers on the strategic value delivered by mega projects in the oil and gas industry. A global survey of 69 managers of mega-projects was conducted. Results showed that information feed to project managers significantly influences the strategic value created by megaprojects. Also some moderating effects of contextual factors on this relationship were found. The contextual factors that influenced project manager decision-making relate to what they perceived to be Senior Management drivers for their projects. However the hypothesized moderating influence of project manager experience on decision-making was not found—an interesting observation. It was found that the extent to which project managers feel in control should influence the scope and quality of information-feed that should be sought. Four risk areas were observed as significant to long-term value creation from megaprojects: government relations; host community relations; contract management and procurement; and the influence of multi-location execution.

近30年太湖流域湿地生态系统服务价值 对景观格局变化的响应：基于“退田还湖” 工程的实施

由于太湖流域湿地生态系统服务价值(ESV)受到"退田还湖"工程实施的影响,定量研究其发展演变规律,能够为流域湿地的保护提供参考。运用RS和GIS技术,以1990、2000、2010和2019年TM遥感影像为数据源,对4个时期太湖流域湿地景观格局动态变化进行研究,并分析"退田还湖"工程实施前后湿地ESV变化规律,探讨工程对湿地生态效益的影响。研究表明:1)1990—2000年,在"围湖造田"工程的影响下,太湖流域湿地总面积减少了3010.35km~2,其中自然湿地减少了4554.01km~2,湿地ESV降低了35.73%;2)2000—2010年,在"退田还湖"工程实施初期,自然湿地的减少趋势得到控制,湿地ESV提高了77.96%,湿地斑块数目(NP)增加了126%,香农多样性指数(SHDI)呈上升趋势;3)2010—2019年,在"退田还湖"工程的推进下,湖泊湿地呈增长趋势,坑塘与水库面积显著增加,受湿地总面积减少的影响,湿地ESV下降;4)总体来看,1990—2019年太湖流域湿地面积减少了29.40%,湿地ESV减少了50.07%。"退田还湖"工程实施前后,太湖流域湿地ESV对湿地...
