随着现在建设工程投资规模、领域的扩大、投资来源多样化、工程项目对环境、经济影响增强,业主工程项目管理应该是包括项目从决策立项到交付使用维护全过程的管理,工程项目的采购也从单纯的施工承包发展到项目管理、工程总承包等多种形式。对于具体的工程项目,其目标也不仅是在限定的投资、工期、质量目标内对工程项目进行综合管理以实现项目预定目标,还应与资金筹措、风险分析、使用维护以及与所在地经济、环境等联系起来,工程项目管理的方法,除了具体的技术性方法,还要向前后期的评价延伸,将工程项目自身作为一个系统来管理,也就是运用系统科学的方法,通过信息反馈与调控,对工程项目进行全面综合管理,包括计划、组织、指挥、协调、控制,以实现项目的综合目标。建设项目管理的核心任务是项目的目标控制。要满足可持续发展的要求。 相似文献

Understandings of informality commonly derive from research undertaken in states perceived as lacking the capacity to regulate the practices of their populations. This Interventions forum aims to expand the geographical parameters of empirical research on urban informality. A more global approach, we argue, also necessitates questioning assumptions that undergird this concept—in particular the underlying conception of the state. In this vein, this collection of papers aims to rethink theories of the state through the lens of informality, and vice versa, to inform and refine the concept of informality through a more thorough understanding of states. In so doing, the contributions engage with concepts that have been central both to theories of the state and to the study of informality, namely governance, agency, legitimacy, sovereignty and legality. Following this introduction setting out our theoretical approach, the Interventions forum unites five empirical studies that discuss the nexus of informality and states in contexts that have been researched less extensively from this perspective, each tackling one of the above‐mentioned concepts. Based on these different entry points, the papers provide novel angles on a state‐theoretical understanding of informality. A concluding essay brings these approaches together, reflecting on the possibilities of translating concepts to different sites. 相似文献

Resource-rich African countries are often saddled with high external indebtedness. Yet, their management of resource endowment, a logical source of debt repayment, also remains a challenge, alongside their characteristic weak institutions. We investigate the relationship between external indebtedness and welfare whilst considering the pervasive influence of both natural resource rents and the quality of institutions. Using a two-stage analysis, we find that the quality of institutions, mineral- and oil-resource rents negatively affect indebtedness, while rents of aggregated natural resources, which include agricultural commodities, increase indebtedness. In the second stage, we find that welfare is enhanced by the quality of institutions, mineral- and oil-resource rents. These sets of results are interestingly conditional on the degree of resource endowment and the income level of countries, alongside the interesting effects of external indebtedness on welfare, both of which, importantly, nuance past results on the “resource curse”. Furthermore, the proxy for welfare matters: the human development index proxy reflects more the theoretical expectations of unsustainable indebtedness on welfare, than does the GDP per capita alternative. These and other results of our paper, which hold useful policy guides for African countries, are robust to alternative estimation techniques and other checks. 相似文献

This paper focuses on the fashion industry, one characterised by issues such as dramatic shifts in the scale and power of
major retail buyers in the market, the advent of retailer own brands, and the nature of sourcing and supply chain decisions,
issues that are increasingly global in nature. The aim of this research is to explore the nature of relationships between
UK high street multiple fashion retailers and their contracted suppliers, many of whom are entrepreneurial firms by most definitions
of the term. Four core themes emerge from the literature and provide a framework for the research, namely, power, process,
partnership, and people. The research approach was qualitative, and conducted over a period of twelve months. The paper ends
with an agenda for future research. 相似文献

以往的常规熏蒸存在着费用高、劳动强度高、残留高等特点,而单纯的环流熏蒸方式虽然在一定程度上节省人力,降低有毒气体对操作人员的身体损害,比较适用于现在的高大平房仓,但是其熏蒸过程相对复杂、各种机械设备运用程度高、熏蒸投药过程长,如果仓房密闭效果不是太好的话还必须进行补药.针对以上情况,经过几年的研究、摸索、对比,最后采用了仓内粮面投药,仓外环流的缓释环流熏蒸方法.此种熏蒸方法降低了熏蒸费用,同时也减少了熏蒸时间和人员接触毒气时间,不需要补药,熏蒸效果相对较好. 相似文献
