文摘Randomized controlled trials(RCTs)provide optimal evidence of the effectiveness and safety of a new drug,a new medical device,or a new therapeutic strategy with the necessary scientific design[1].Traditional electronic data collection(EDC)systems for clinical trials primarily focus on data entry,validation,and compliance monitoring.However,their reliance on centralized architectures introduces vulnerabilities in data security and integrity。

文摘This paper considers a platform-led e-commerce supply chain consisted of a supplier and an online platform.The supplier distributes products through the online platform operated with reselling or agency mode.The online platform invests in blockchain technology and the supplier shares partial investment cost.The paper formulates four platform Stackelberg models to analyze the optimal pricing and information traceability level without and with cost-sharing mechanism under two platform modes.Through the model comparison,the impact of the cost-sharing mechanism and the choice of the platform mode are investigated.Results suggests that the cost-sharing mechanism is effective in improving two members profits under two platform modes.Without cost-sharing mechanism,the supplier benefits from the agency platform mode while the online platform benefits from the reselling platform mode,and thereby the win-win outcome cannot be achieved between two members.With cost-sharing mechanism,the supplier benefits from the agency platform mode while the online platform benefits from the reselling(agency)platform mode with a low(high)blockchain investment efficiency,and thereby the win-win outcome can be achieved between two members through the agency platform mode under a high blockchain investment efficiency.This paper further extends to the case that the online platform operates with hybrid mode,and derive the insights into the value of the agency platform mode in achieving the win-win outcome through the cost-sharing mechanism.

文摘The application of Blockchain Technology(BT)makes consumers trace more product information and enhances their trust in the product brand,but it also brings cost pressure to some participants who adopt the technology.Thus,it is particularly important how to encourage and support more enterprises to participate in BT.This study incorporates the altruistic preference into a BT-enabled three-echelon supply chain consisting of a powerful retailer,a supplier,and a manufacturer.We investigate the optimal strategies of the supply chain in different scenarios:without and with the BT,and without and with the altruistic preference.Then,we explore the effects of the BT and the retailer’s altruistic preference on the profit performance of the supply chain system.The results show that the retailer,the manufacturer,and the supplier do not always benefit from the traceability of the BT,and while the powerful retailer’s altruistic preference decreases his or her own profit but increases the profits of the manufacturer,the supplier,and the entire supply chain.Finally,a profit redistribution mechanism is designed to coordinate the supply chain with the retailer’s altruistic preference under the BT.

文摘The integration of Blockchain Technology(BT)with Digital Twins(DTs)is becoming increasingly recognized as an effective strategy to enhance trust,interoperability,and data privacy in virtual spaces such as the metaverse.Although there is a significant body of research at the intersection of BT and DTs,a thorough review of the field has not yet been conducted.This study performs a systematic literature review on BT and DTs,using the CiteSpace analytic tool to evaluate the content and bibliometric information.The review covers 976 publications,identifying the significant effects of BT on DTs and the integration challenges.Key themes emerging from keyword analysis include augmented reality,smart cities,smart manufacturing,cybersecurity,lifecycle management,Ethereum,smart grids,additive manufacturing,blockchain technology,and digitalization.Based on this analysis,the study proposes a development framework for BTenhanced DTs that includes supporting technologies and applications,main applications,advantages and functionalities,primary contexts of application,and overarching goals and principles.Additionally,an examination of bibliometric data reveals three developmental phases in cross-sectional research on BT and DTs:technology development,technology use,and technology deployment.These phases highlight the research field’s evolution and provide valuable direction for future studies on BTenhanced DTs.
文摘With the continuous advancement of technology and the rapid development of the Internet,digital education has gradually become an important component of current educational models.Among them,blockchain technology,as an emerging information processing and storage method,demonstrates tremendous potential in ensuring data security,enhancing teaching quality,and improving efficiency.Digital education stands out as a crucial aspect of educational modernization.Blockchain technology,a new information technology integrating cryptography,distributed computing,and other cutting-edge technologies,is profoundly impacting the global education landscape with unparalleled security,transparency,and innovation.This paper comprehensively reviews the potential value of blockchain technology in digital education,meticulously analyzes the problems encountered in its implementation,proposes corresponding countermeasures,and ultimately outlines a hopeful yet challenging vision for future education.
文摘As the world grapples with increasing environmental challenges,innovative technologies are essential for promoting sustainability and accountability.This study examined the impact of environmental performance indices(EPIs)on the growth and investment trends of blockchain-based sustainability-focused companies in 15 countries(Belgium,Czechia,Denmark,Estonia,Finland,France,Germany,Italy,Norway,Poland,Sweden,Spain,Switzerland,the United Kingdom,and the United States)from Europe and America during 2010-2022.This study used the negative binomial regression model to assess the relationship between EPIs and blockchain-based sustainability-focused companies based on the data from the CrunchBase and EarthData.Results indicated that in ecosystem vitality,national terrestrial biome protection efforts were negatively correlated the formation of blockchain-based sustainability-focused companies,while global terrestrial biome protection efforts and marine protected areas had a positive impact on the formation of these companies and the number of funding rounds.In environmental health,PM2.5 exposure had a positive impact on the number of funding rounds.Conversely,pollutants such as sulfur dioxide(SO_(2))and ocean plastics deterred the formation of blockchain-based sustainability-focused companies and reduced the number of funding rounds.In climate change performance,adjusted emission growth rate for carbon dioxide(CO_(2)),adjusted emission growth rate for F-gases,and adjusted emission growth rate for black carbon had a significantly positive impact on the formation of blockchain-based sustainability-focused companies.Conversely,adjusted emission growth rate for Nitrous Oxide(N_(2)O)and projected greenhouse gas emissions in 2050 negatively affected the formation of these companies.These findings highlight the dual role of EPIs as driving factors and barriers in the development and investment of blockchain-based sustainability-focused companies in countries from Europe and America.
