The socio-technical theory concerning technical and social systems is introduced. The emergency management system concepts of “technology enabling” and “enabling value creation” are defined according to bibliometric analysis and socio-technical theory. Second, a research framework that includes technology enabling and enabling value creation for the decision-making paradigm in emergency management according to the big data environment is constructed. A detailed analysis approach from intelligent emergency technology enabling to enabling value creation in emergency management is proposed. Finally, earthquake disasters are taken as examples, and specific analyses of the intelligent emergency enabling and enabling value creation are explored; enabling value creation is discussed based on measurable indicators. The clear concept of emergency management system technology enabling and enabling value creation, as well as the detailed analysis approach from intelligent emergency technology enabling to enabling value creation, provide a theoretical bases for scholars and practitioners to evaluate the value (performance) of intelligent emergency for the first time.</div></div>","PeriodicalId":100353,"journal":{"name":"Data Science and Management","volume":"8 1","pages":"Pages 11-22"},"PeriodicalIF":0.0,"publicationDate":"2024-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141409093","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study provides an updated learning strategy for artificial neural network (ANN) to address data categorization problems caused by unbalanced data. Compared to traditional approaches, the augmented ANN’s 92% accuracy is a significant improvement owing to the network’s increased resilience to disturbances and computational complexity, brought about by the addition of a random weight and standard scaler.

As this immersive virtual world gains prominence, the role of avatars and the digital representations of users in shaping educational experiences within a metaverse becomes increasingly crucial. This study examined the design of avatars and their effectiveness in virtual education. Using the cognitive walkthrough (CW) method, a well-established user-centric assessment approach, this study examined how users engage in avatar design in virtual educational settings, highlighting their cognitive processes. Through the CW approach, this study identified usability issues and learning challenges, providing valuable insights into the user experience. The investigation focuses on the VRoid platform for avatar design, selected for its user-friendly interface and robust customization features. Participants (n ​= ​12; six men and six women) from diverse educational backgrounds were carefully selected to offer a comprehensive range of perspectives. They performed avatar design tasks that closely mirrored the learning environment of the metaverse, followed by in-depth post-exercise interviews. The findings of this study highlight the essential role of avatar design in enhancing user engagement and improving the learning outcomes of virtual education. Furthermore, we provide practical recommendations for educators and designers to effectively leverage avatar innovation.
