Work Design and Integration Glitches in Globally Distributed Technology Projects

In a technology project, project integration represents the pooling together of complete, interdependent task modules to form a physical product or software delivering a desired functionality. This study develops and tests a conceptual framework that examines the interrelationships between the elements of work design, project integration challenges, and project performance. We identify two distinct elements of work design in technology projects: (i) the type of project organization based on whether a technology project spans a firm boundary (Domestic‐Outsourcing) or a country boundary (Offshore‐Insourcing) or both boundaries (Offshore‐Outsourcing) or no boundaries (Domestic‐Insourcing), and (ii) the joint coordination practices among key stakeholders in a technology project—namely, Onsite Ratio and Joint‐Task Ownership. Next, we measure the effectiveness of project integration using integration glitches that capture the incompatibility among interdependent task modules during project integration. Based on analysis of data from 830 technology projects, the results highlight the differential effects of distributed project organizations on integration glitches. Specifically, we find that project organizations that span both firm and country boundaries (Offshore‐Outsourcing) experience significantly higher levels of integration glitches compared to domestic project organizations (Domestic‐Outsourcing and Domestic‐Insourcing). The results further indicate that the relationship between project organization type and integration glitches is moderated by the extent of joint coordination practices in a project. That is, managers can actively lower integration glitches by increasing the levels of onsite ratio and by promoting higher levels of joint‐task ownership, particularly in project organization types that span both firm and country boundaries (Offshore‐Outsourcing). Finally, the results demonstrate the practical significance of studying integration glitches by highlighting its significant negative effect on project performance.     

铁路既有线电气化改造工程安全预警模型研究

铁路既有线电气化改造施工工程与新线建设工程相比具有的特点是：连续的工程施工流程被分割、分散;工程施工不能对已建立的设施和设备造成伤害;受到客流及货流等人为影响因素多。施工环境的特殊性决定了既有线电气化改造工程施工的高风险性。根据安全管理理论及人－机－环系统工程理论,既有线电气化改造工程施工中的不安全因素有人员因素、设备材料因素、环境因素、安全管理因素等。分析安全影响因素可以建立安全预警模型,在一定程度上预防安全事故的发生,实现安全生产。

A Strange Kind of Science: Making Sense of the Millennium Villages Project

Abstract

The Millennium Development Goals (MDGs) are often critiqued as a strategy of social engineering. This analysis would seem to be supported by the case of the Millennium Villages Project (MVP), the world's leading programme for the achievement of the MDGs. At the level of its discursive articulation, the MVP appears as a scientific ‘proof of concept’ for the comprehensive engineering of neoliberal social orders. But its evaluation methodology has been widely criticised for a lack of scientific rigour, and field research that I conducted in the Ruhiira Millennium Village in Uganda in 2013 revealed serious problems of implementation. I argue that the MVP is better understood not as a strategy of social engineering but as the staging of a social fantasy in which the constitutive antagonisms of capitalist development are concealed. In this fantasy space, the MDGs function to fill the gap between the promise of development and the impossibility of capitalism without poverty.     

水利水电工程建设对移民社会系统的影响与重建

水利水电工程的建设可能会对移民的生产生活方式、社会交往与社会心理、基础设施与公共设施、社会关系网络、收入与支出、就业与生计模式等产生影响。随着社会的转型,移民发展观和安置理念的转变,移民政策的完善,安置模式的创新,工程建设对移民社会系统的影响逐步减小,但无法完全消除。为了实现移民社会系统的恢复与重建,需要优化安置点的选择,对移民实施外援和内源干预,提供就业服务和能力再造,加强资源倾斜与整合力度、加强移民制度建设,通过上述手段的合力共同促进移民社会系统的重建。     

少数民族地区水利水电工程移民问题探讨

西部少数民族地区是我国水利水电开发的重点区域。少数民族地区移民的特殊性对移民安置的实施提出了挑战。综合利用文献和田野经验,在梳理少数民族地区移民安置主要研究领域的同时,分析了研究的前沿科学问题。已有研究主要围绕少数民族地区移民的搬迁补偿、移民安置、移民适应、移民融合等问题。后续研究中,需要关注少数民族人地关系与生计、少数民族宗教信仰与文化习俗及其恢复补偿、少数民族移民可持续发展研究等。     

现金流不确定状态下财务指标IRR的应用探析

内含报酬率是目前评价项目可行性的主要指标之一,在应用时都是建立在对现金净流量值给出确切估计的基础上,但在实际经营活动中现金净流量存在着很多不确定性,往往是不能确切地估计出来。在此基础上考虑了各期现金流是概率排序型、各期现金净流量值是一个区间数以及各期现金净流量满足特定的概率分布这三种不确定状态下的IRR应用情形,使其能够更加贴近现实,提高项目评估的准确性。
