Alternative Economics and Sustainable Future: Diverse Cultures/Beliefs/Values as Indispensable Factors

This article argues for a theoretical framework of alternative economics pertinent to Sustainable Development. The alternative economics requires an appropriate belief/value system based on a dynamic, sound and holistic society-specific culture (abbreviated as “Culture”). To represent the Culture-based belief/value system, a general framework for overarching Integral Harmony is introduced as an appropriate social value system for a paradigm shift toward sustainability. Such a social value system is now related to the value premises of the alternative economics. Then, the framework of alternative economics is explained in terms of basic theoretical construct that is simplified as a summary equation comprising value and real aspects. Finally, a typical working of the alternative economics is demonstrated diagrammatically as constant interactions of the value aspect and the real aspect (abbreviated as “Value-Real Interactions”).     

Categorization of risk factors for distributed agile projects

ContextOrganizations combine agile approach and Distributed Software Development (DSD) in order to develop better quality software solutions in lesser time and cost. It helps to reap the benefits of both agile and distributed development but pose significant challenges and risks. Relatively scanty evidence of research on the risks prevailing in distributed agile development (DAD) has motivated this study.ObjectiveThis paper aims at creating a comprehensive set of risk factors that affect the performance of distributed agile development projects and identifies the risk management methods which are frequently used in practice for controlling those risks.MethodThe study is an exploration of practitioners’ experience using constant comparison method for analyzing in-depth interviews of thirteen practitioners and work documents of twenty-eight projects from thirteen different information technology (IT) organizations. The field experience was supported by extensive research literature on risk management in traditional, agile and distributed development.ResultsAnalysis of qualitative data from interviews and project work documents resulted into categorization of forty-five DAD risk factors grouped under five core risk categories. The risk categories were mapped to Leavitt’s model of organizational change for facilitating the implementation of results in real world. The risk factors could be attributed to the conflicting properties of DSD and agile development. Besides that, some new risk factors have been experienced by practitioners and need further exploration as their understanding will help the practitioners to act on time.ConclusionOrganizations are adopting DAD for developing solutions that caters to the changing business needs, while utilizing the global talent. Conflicting properties of DSD and agile approach pose several risks for DAD. This study gives a comprehensive categorization of the risks faced by the practitioners in managing DAD projects and presents frequently used methods to reduce their impact. The work fills the yawning research void in this field.     

复种指数遥感监测研究进展

复种指数是对耕地资源利用状况的一种度量,其对于指导农业生产及研究气候变化等具有重要意义。利用遥感技术进行复种指数监测,不仅客观、高效、低成本,而且可以获取更佳的空间分布信息,近些年已成为农业遥感领域的研究热点。对复种指数遥感监测进展进行了综述:首先归纳和梳理了已有的几种复种指数遥感监测方法,并分析了各种方法的优缺点;然后在总结该领域研究现存关键问题的基础上,探讨了未来的发展趋势:(1)在内容上丰富,加强特殊的作物熟制信息监测;(2)在空间上拓展,加强地形复杂区域的复种指数监测;(3)在时间上延伸,加强复种指数长期的动态变化监测。     

An environment for End-User Development of Web mashups

End-User Development aims to find novel ways that are suitable and intuitive for end users to create their own applications. We present a graphical environment in which users create new mashups by directly selecting interaction elements, content and functionalities from existing Web applications without requiring the intervention of expert developers. Then, users just need to exploit a copy–paste metaphor to indicate how to compose the selected interactive content and functionalities in the new mashup. The environment is enabled by a Web-based platform accessible from any browser, and is suitable for users without particular programming skills. We describe the architecture of our platform and how it works, including its intelligent support, show example applications, and report the results of first user studies.

面向大型分布式软件项目的敏捷开发模型研究

面向分布运行的大规模信息化项目,支持基于广域网络的协同开发团队,规避软件过程风险,确立在需求演进状态下实现"业务驱动开发"的软件过程管理模型,是软件工程领域的重要课题。我们采用的方法是:基于一个支持分布式软件开发的支撑平台,并拓展XP的基本属性,改"结对编程"为"分布式编程"和"IRC资源分配",从而完善传统XP存在的先天性不足,保证软件开发元素的完整性和关联紧密性,提高了系统开发效率和软件制品质量。
