Some issues in blockchain for accounting and the supply chain,with an application of distributed databases to virtual organizations

This paper reviews some recent blockchain‐based applications for information capture, distribution and preservation. As part of that review, this paper examines two key concerns with current blockchain designs for accounting and supply chain transactions: data independence and multiple semantic models for the same information distribution problem. Blockchain applications typically integrate database, application and presentation tiers all in the same ledger. This results in a general inability to query information in the ledger and other concerns. Further, since most applications appear to be private blockchain applications, there is a concern of agents needing to accommodate multiple blockchains depending on who their trading partners are and what they request. Finally, this paper uses a distributed database to design a ‘blockchain‐like’ system for virtual organizations.     

From the margins: globalization with(out) home economics

Pies and peas, noughts and crosses, fish and chips, chicken and egg, teaching and learning, home economics and . . . globalization? In psychotherapy, this simple technique of providing a word and another automatically coming to mind is called free association and some of the internationally accepted pairings are noted above. Do we want ‘home economics’ and ‘globalization’ to have an automatic association? In this paper, I argue that home economics must make a shift from the margins of patriarchy by re‐thinking the ways in which the field is legitimized and positioned if it is to be a key player in taking on the challenges and dilemmas raised by globalization.

后疫情时期服务业发展的思考与对策——基于服务生态系统的视角

服务生态系统是服务企业进行资源整合、服务交换和价值共创的重要场所,也是数字经济背景下服务产业实现升级发展的重要手段。本文基于服务生态系统理论,通过文献梳理阐明了服务业服务生态系统中价值创造、参与者关系和共享制度等基本问题,分析了新冠肺炎疫情对服务业造成的巨大影响即减少了参与者互动和价值共创、缩小了生态系统规模、加剧了生态系统动荡、催生出大量创新。最后为后疫情时期的服务业发展提出加强服务企业扶持力度、通过科技手段搭建互动桥梁、坚定服务业的发展方向、利用变革期大力发展服务创新等对策建议。     

基于可持续发展的建设项目后评价问题探讨

建设项目后评价作为项目管理过程中的一个重要环节,从可持续发展对建设项目客观要求的角度出发,建设项目后评价系统不仅突出重视环境资源的价值,而且从动态角度强调对其永续利用、代际公平等,在实现可持续发展的同时更好地发挥后评价的作用,是对项目前期评价工作的补充和完善.
