The communities around the Kaligandaki Gorge Hydropower Project in the Myagdi District of Nepal depend on river flow for most of their rural and agricultural needs. Without a sustainable development plan, the growing population of the region, confined in an area with declining water resources, will face serious challenges to economic growth. Meteorological data show increasing annual average rainfall at a slight rate of about 0.284 mm/year, with erratic annual percentage change in rainfall in the area. The mean and minimum temperatures show decreasing trends at the rates of 0.05-C and 0.14-C per year, respectively. An assessment of the impacts on water availability for domestic and irrigation usage in the face of competing demands caused by the hydropower development project in the Kaligandaki Gorge was undertaken. The water demand and supply modeling were conducted using the water evaluation and planning (WEAP) model, based on discharge data from the Kaligandaki River, which were obtained from the Department of Hydrology and Meteorology, Nepal. The available data from 2001 to 2003 were used to estimate the model parameters while the stability of these parameters was tested with a validation period from 2004 to 2007. The performance of the model was assessed through statistical measures of calibration with the root mean square error and coefficient of determination, whose values were 0.046% and 0.79, respectively. Two scenarios were created in addition to the base case scenario: the discharge decrement scenario and new irrigation technology scenario. Analysis showed that a prioritization of demands will be necessary in the area in the near future for the purpose of sustainability of water resources, due to climate change impacts.展开更多

Their per-unit cost does not decrease but increase with the growth of such projects product size. Thus this is diseconomies of scale that occur in them. The significance of this phenomenon results from the fact that it is commonly considered to be one of the fundamental objective causes of their low effectiveness. This is of particular significance with regard to Business Software Systems （BSS） D＆EP characterized by exceptionally low effectiveness comparing to other software D＆EP. Thus the paper aims at answering the following two questions： （1） Do economies of scale really not occur in BSS D＆EP？ （2） If economies of scale may occur in BSS D＆EP, what factors are then promoting them？ These issues classify into economics problems of software engineering research and practice.展开更多

It is imperative that major infrastructure projects (MIPs) adhere to the principles of sustainable development in order to promote sustainability. This requires identifying sustainable strategies that are capable of serving as a guide to inculcating sustainability into major infrastructural projects. The current paper examines ways of inculcating sustainability into infrastructure projects bearing in mind that construction, maintenance and the way we use facilities have significant impacts on the environment. In addition to the fact that, decision making tools on methods of inculcating sustainability into infrastructure project appear too complex to stakeholders;and in most cases they do not provide stakeholders the necessary information required to make a good judgement. Hence, the present paper relies on desk study to gather existing data on infrastructure project and sustainable development. Existing data are obtained from books, scholarly articles and the WebPages of municipal authorities in the UK. Amongst other findings, the paper reveals that the utilization of environmental impact statements and environmental assessment documents at the formative stage of projects will aid the assessment of the level of sustainability to be achieved in any infrastructure development.展开更多

In line with this issue, this study investigates a wide range of relevant literature, proposes a new conceptual framework for managing risk in software development projects, introduces new conceptual factors, brings out their interrelation, and suggests new prospects and managerial implications for both practitioners and academics. The conceptual framework has two basic axes. Firstly, the determination of the impact of constructs such as Project Characteristics, Project Risk Management Team, Risk Identification Approaches, and Project Quality on the level of Project Risk. The majority of the items used to measure these constructs are proposed for the first time in the literature. Additionally, the assessment of the impact of Project Risk (and all of the dimensions that compose it), simultaneously with the estimation of the impact of the Residual Performance Risk on the final subjective and objective Project Performance could provide project managers with a better picture of the effectiveness and adequacy of their risk management practices.展开更多

文摘Bargaining between the host country and oil companies is very common to international oil and gas development projects.The existence of information asymmetry gives the host country an endogenous bargaining advantage.Foreign oil companies might change their unfavorable negotiating position by changing the order of bidding and adjusting bidding strategies.This paper introduces both factors into a bilateral bargaining model to study the impact of information asymmetry and bidding order on the strategy and equilibrium returns of oil companies.According to the ownership of the right to bid first,two scenarios are designed for the model to compare the equilibrium returns of the host country and oil companies.The results show that:1)There is a first-mover advantage in the process of bilateral bidding,so oil companies better bid first;2)The information asymmetry will lead to a higher nominal income ratio of oil companies and a lower nominal income ratio of the host country,but it doesn’t affect the total income ratio at all.
文摘The frequently observed positive impact of adopting risk management strategies on projects’ overall outcome has led many software development organizations to appreciate its significant role in the pursuit of cost reduction, schedule overruns decrease and, generally, improved performance. In line with this issue, this study investigates a wide range of relevant literature, proposes a new conceptual framework for managing risk in software development projects, introduces new conceptual factors, brings out their interrelation, and suggests new prospects and managerial implications for both practitioners and academics. The conceptual framework has two basic axes. Firstly, the determination of the impact of constructs such as Project Characteristics, Project Risk Management Team, Risk Identification Approaches, and Project Quality on the level of Project Risk. The majority of the items used to measure these constructs are proposed for the first time in the literature. Additionally, the assessment of the impact of Project Risk (and all of the dimensions that compose it), simultaneously with the estimation of the impact of the Residual Performance Risk on the final subjective and objective Project Performance could provide project managers with a better picture of the effectiveness and adequacy of their risk management practices.
文摘Mobile Application Development is a well-known undergraduate specialized course majoring in Computer Science and Software Engineering.Since it is a rapid developing technique and requires extensive project samples to help understand,current teaching mechanism has still limitations in rare real project examples,outdated course contents,and lack of automatic assessment platforms.In order to improve the teaching effects and cultivate students’practical ability,we employ this teaching reform with industrial projects,double instructors,and automatic assessment platform to allow students participating in every course process.We aim to improve students’practical and collaboration ability during conducting the project spontaneously,and cultivate their awareness of self-learning and lifelong learning.Our classroom feedback has demonstrated that this teaching reform is effective on improving students’practical abilities,learning initiatives and comprehensive qualities.

文摘To keep up with the time,culture is integrated to large-scale construction project management in China,which will absolutely add more vitality into construction project management in our country.Engineering culture is an integration of project construction and engineering culture.However,engineering culture development enjoys its own particularity as a project is constructed once only within a limited period of time.This paper gives affirmative opinion that engineering culture development in large-scale projects backs project management on the basis of thorough investigation of engineering culture development in Sutong Bridge Project and after deepened analysis,proposes new thinking pattern of engineering culture development in large-scale projects in a systematic manner,including thorough understanding of the essence of engineering culture,principle and contents of engineering culture development as well as efficient method in respect of establishment and implementation of engineering culture,and therefore provides a standard reference and systematic thinking pattern for engineering culture development in future large-scale projects.
文摘Although previous studies on Korean manufacturing firms have empirically analyzed the causal relationship between activities during the FFE(Fuzzy Front End)and success of NPD(New Product Development)of Korean manufacturing firms,no study has concretely focused on Korean ICT(Information and Communications Technology)firms and their FFE activities.The main aim of this study is to identify the activities of these firms during their FFE and provide managerial insights into the other ICT firms.The authors conducted a survey(106 valid responses)that their FFE activities on new product development project managers in Korean ICT firms.The results showed that even though new product development managers of Korean ICT firms did not search for ideas systemically,they communicated with those departments/divisions that had frequent interaction with customers for idea assessment,with the active involvement of middle-or higher-level managers.They thoroughly established initial plans in the pre-development stages and seriously analyzed competitors’products and direct and indirect customer interactions in their market survey activities.
