As our understanding of the Qing empire and its various borderlands has evolved, so too have we come to appreciate China's early modem commercial sophistication. In recent North American studies of the Qing, the links between commerce and conquest have come under investigation, and we are increasingly urged to pay attention to merchants and merchant capital. But how should we understand the relationship between merchants and the Qing empire in the borderlands? This article surveys selected work on the borderlands and commercialization, primarily in the Northwest and Southwest. The goal is to initiate a more comprehensive discussion of how to understand the intersection of commerce and empire while also making some suggestions for ways that borderlands history might shape future work on China. 展开更多

Blockchain technology is a shared database of logs of all consumer transactions which are registered on all machines on a network.Both transactions in the system are carried out by consensus processes and to preserve confidentiality all thefiles contained cannot be changed.Blockchain technology is the fundamental software behind digital currencies like Bitcoin,which is common in the marketplace.Cloud computing is a method of using a network of external machines to store,monitor,and process information,rather than using the local computer or a local personal computer.The software is currently facing multiple problems including lack of data protection,data instability,and reliability.This paper aims to give the highest security for multiple user environments in cloud for storing and accessing the data in blocks.The users who are legitimate are only allowed for storing and accessing the data as like a secured block chain approach.As like the Blockchain which does not require a centralized system for transactions,the proposed system is also independent on centralized network interface.The decentralized system is developed in such a way to avoid counterfeiting.The system enables the fabricator to spend less or null resources to perform the validations for its direct operated stores.This ensures the product fabricator to avoid the circulation of its duplicate products.The customer as an end-user is also ensured to have only the genuine products from the fabricator.The Fabricator(F),Merchant(M)and consumer(C)forms an interconnected triangular structure without allowing any counterfeiting agents in their secured cloud chain.The pro-posed approach provides the stability in the security system of the cloud using the chaining mechanism within different blocks at each node.It takes roughly 4.7,6.2,and 7.5 ms,respectively,to register each node in the proposed system for 5,10,and 15 nodes.The overall registration time for each scenario is 11.9,26.2,and 53.1 ms,despite the fact that each node’s registration time was greatest for 10 nodes.By looking at the data,it’s clear that the number of nodes is a func-tion of time. 展开更多

William Shakespeare is the most well-known playwright in the world.The Merchant of Venice is one of the four great comedies by William Shakespeare.It is set during the Elizabethan period with rapid economic development and wide spread Renaissance humanism.Kindness and love are the main themes of the play.Against the backdrop of the spirit of humanism,the female characters in the play have preliminary feminist spirit and subject consciousness though there are some limitations.This article analyzes the feminist spirit in the play and women’s progress on their road of liberation.It suggests that while reflecting the initial emancipation of women in the West in the 16th century,the play also reveals the reality of the enormous social barriers on the road of women’s emancipation.The emancipation of women is an enduring topic in the development of society and a goal that people all over the world are still striving for. 展开更多
