端午节的历史传承与当代复兴     

黄涛  杨雯雯 《温州大学学报(社会科学版)》2011,(4)

端午节在战国时代初步形成,源于古人虔诚的原始信仰。原始信仰是当时节俗传承的足够动力。魏晋时期原始信仰比以前淡化了,端午节传承的原初动力也消弱了,这时人们加入了纪念屈原等历史人物传说来解释端午习俗,为端午节增加了新的文化内涵和习俗。但是由于端午节习俗不重视家庭团聚和祭祀祖先,在契合儒家文化方面不很显著,因而在魏晋以后的儒教时代出现了传承动力不足的问题。到现代社会,端午习俗面临传承危机。但经研究可见到,端午习俗包含着适合现代文化的丰富要素,可以进行适应现代社会的调适、更新。在重视非物质文化遗产保护的社会背景下,它更有了复兴的契机和动力。  相似文献

A blockchain-based framework of cross-border e-commerce supply chain     

《International Journal of Information Management》2020

Blockchain technology provides us a new tool to solve the product traceability problem in supply chain management. This research focuses on the cross-border e-commerce context, to propose a blockchain-based framework, and develop a set of corresponding techniques and methods for achieving traceable products and transactions in supply chain management. A general blockchain-based product traceability framework is introduced. This framework is based on a cross-border e-commerce supply chain context, incorporating a series of blockchain-based models, including multi-chain structure model, data management model and block structure model. Several core methods and algorithms are also developed, such as information anchoring method, key distribution method, information encryption algorithm and anti-counterfeiting method. The framework, models and methods form a complete and comprehensive solution, which are evaluated by applying to several typical problems and attack cases. The case analysis results show that the framework, models and methods can successfully deal with key recover problem, and protect against clone attack, counterfeit tag attack and counterfeit product attack. The effectiveness, extendibility, security, implementation and governance issues of applying these solutions are also discussed. This research contributes to the theoretical and practical literatures on blockchain technology, cross-border e-commerce and supply chain management research fields.  相似文献   

Blockchain in the operations and supply chain management: Benefits,challenges and future research opportunities     

《International Journal of Information Management》2020

Blockchain technologies have captured the imagination of scholars, managers, and practitioners around the world. It is widely accepted by these actors that blockchain is not a buzzword, but a highly disruptive technology that is already remodeling the organizations and their supply chain business models. Despite the meaningful advance in the last years, blockchain applications regarding the operations and supply chain management (OSCM) are still in their infancy. Little is known about the role of blockchain in terms of operations traceability, as well in areas such as e-commerce, agriculture, public services, etc. Therefore, this Special Issue seeks to extend our understanding of blockchain applications in OSCM and how firms create and capture business value with blockchain. To this effect, this Special Issue will provide a well-articulated and in-depth discussion of the role of blockchain in creating value in the domain of OSCM. Specifically, it is expected that more light is shed on how blockchain integrates with and impacts new business models, transforms relationships, and improves performance and competitive advantage in OSCM. Also, the evolution of blockchain was reviewed in order to provide a strong background to the readers. The literature review was performed taking into account a bibliometric perspective of blockchain-related publications. The review supports the importance of this Special Issue by highlighting the urgent needs of this topic in this reputable journal. Finally, we provide future research directions and a guide for the papers presented in this Special Issue.  相似文献
