雍正初年,清世宗在钱塘江海塘修筑中提出了“一劳永逸”的目标,并且为实现治水目的,在意识形态层面将海塘工程纳人到了“天人感应”理念的范畴。但是,“天神赐佑”、“非人力所能”与“一劳永逸”目标之间存在着明显的逻辑矛盾,从而对塘工修筑产生了深刻影响。意识形态与水利工程的交融,因此成为雍正朝治水政治的一大特点。  相似文献

Public investment project (PIP) plays an important role in the China economy. In order to improve the project management performance of public projects, the government is searching for a scientific system to build a construction management supervision mode. This paper introduces the policy background and connotation of Agent Construction System (ACS). As a public investment construction management model, ACS, is gradually being incorporated into the legal framework, it is necessary to improve the construction agent supervision mechanism. This article analyzes the supervision mechanism of construction agent quality management under the principle of two-stage agent mode and establishes an agent quality self-control system and a government co-supervision system. These systems take the contract management as the core and the project quality objective as the guidance. These systems also consist of a two-dimensional framework of vertical self-control and horizontal supervision, which form a quality supervision mechanism. Based on Rough Set theory, the article proposes the idea of building an agent quality self-control and government co-supervision model, and illustrates it with a flow chart for building the model, which paves the way of quantitative research for the future.  相似文献

The paper focused on evaluation of stakeholder capacity to implement the millennium village primary school meal project in Kenya. The study which was anchored on the stakeholder theory as well as the Context Input Process Product (CIPP) model of evaluation used mixed methods research design with ex-post facto and case study as its two research elements. The mixed methods was adopted because when both qualitative and quantitative approaches are used in a single study, the strengths of both produce a research synergy in which the collective benefits are greater than what is obtained from either approach when used alone. A sample size of 186 participants was selected from seven (7) primary schools using stratified random sampling. The participants selected purposively included pupils, teachers, head teachers, parents, Area Education Officer (AEO) and project staff. Data was collected using questionnaires, face to face interview guide, Focus Group Discussion (FGD) and document analysis guide. The study findings indicated that the project was implemented with great success as indicated by stakeholders’ capacity to understand project objectives, their involvement in project planning and implementation and their positive attitude towards the project. This has contribute to poverty reduction in the community through the project and sustainable approaches for project implementation.  相似文献

针对由一个制造工厂和多个区域服务中心组成的服务型制造企业,研究了考虑生产时间和服务时间均具有随机性且工期可指派的产品服务系统(PSS)订单调度问题。首先以最小化订单提前、误工和工期指派费用的期望总额为目标构建问题的优化模型,然后分析目标函数近似值的最优性条件,据此提出加权最短平均生产时间排序规则,并结合该规则与插入邻域局部搜索设计了启发式算法对问题进行求解,最后通过数值仿真验证算法的可行性和有效性。研究表明,提前费用偏差对PSS订单调度与工期指派决策的影响很小,因此企业管理者无需准确估计库存费用也能制定出比较有效的PSS订单调度策略;而工期指派费用偏差对决策结果的影响非常大,因此企业管理者在决策时必须谨慎估计该项费用。  相似文献

项目教学法是德国"双元制"职业院校中盛行的教学模式,但多用于工科专业。自引入我国以来,对于工科类高职院校来说,效果非常明显,但对于财经类专业应用效果不尽人意。本文选取财经类专业岗位财务管理岗位实际工作情境之一——筹资,以项目教学法为基础,构建了包括教学情境的设计、学生学习步骤一览表的制定、学生学习步骤计划书的设计、学生自我测试及测试题库的设计、工作任务的设计、参考信息的提供、学习方法和策略的指导、项目成果的展示要求、教学评价方法的制定共9个部分组成的课堂教学体系。  相似文献

This study provides a unique perspective in the field of cross-cultural management by exploring the relationship between “cultural dissonance”—the gap between cultural values and actual practice—and effective leadership attributes in the Middle East and North Africa (MENA) region. Incorporating cultural dissonance into implicit leadership theory, the study uses measurements of dissonance on nine cultural dimensions to identify particular leadership preferences in seven MENA countries. The overall findings suggest that societies prefer leaders who counterbalance cultural dissonance by allowing space for negotiations by members of society to reduce disparities between cultural values—“the way things should be”—and actual practices—“the way things are.” The greater the disparity between cultural values and practices, the greater the citizens' desire that leaders act as agents of change by creating space for negotiation.  相似文献

剩余收益模型(Residual Income Model,RIM)是评估公司权益价值的经典模型,特别地,奥尔森系列剩余收益模型由于可以利用历史财务与会计数据而得到广泛运用。本文在一般剩余收益模型的基础上,运用规范研究、逻辑推理等方法,基于产品生命周期理论,即项目处于产品生命周期的不同阶段时,其净资产收益率不同,在增长期的净资产收益率持续上升,衰退期的净资产收益率持续下降,而成熟期的净资产收益率则围绕行业平均水平波动,从理论上就项目投资价值的评估构建了多阶段剩余收益项目决策模型,并就所构建的多阶段剩余收益项目决策模型进行参数赋值分析。研究结果表明该新构建的决策模型具有较好的理论和运用价值,可以作为一种有效的项目投资决策模型。本文的研究一是拓展了剩余收益模型的应用,从主要用于对公司权益价值的估值拓展至对项目投资决策的评估;二是有利于寻求项目投资决策的价值最大化。  相似文献

Many optimisation problems arise in managing the Blood Donation (BD) supply chain. Most of them have been addressed in the literature, while other problems, e.g. donation scheduling, have not been sufficiently addressed so far. However, blood collection from donors may have a disruptive impact on the entire BD supply chain if not properly managed. For example, scheduling donation appointments based on some system metrics may improve the flow of blood units through the BD supply chain and increase the quality of service perceived by donors. In this short communication, we present the donation scheduling problem and highlight the lack of work in the literature that deals with this problem. Then, we analyse the impact of an unbalanced flow of blood units on the BD system and the benefits that may derive from a suitable appointment scheduling. Finally, we propose suggestions for future research in BD collection scheduling that may improve the BD process.  相似文献
