Global app marketplaces make families in foreign countries easily accessible to developers, but most scholarship on joint media engagement (JME) between parents and children reports on data from participants in Western contexts. We conducted an observational lab study to examine how preschoolers (age 3-5) and parents (N=74) from three different regions of the world (communities in China, Taiwan, and the United States) engage with two types of tablet games: an instructional game with goals and an exploratory, open-ended game. We found systematic differences among groups and between games. For example, parents from China and Taiwan frequently picked up their child's hand and used it as a tool to engage with the screen, a practice parents in our U.S. sample did not employ. Dyads from all three samples exhibited more warmth when playing an instructional game than an exploratory one. Our results suggest that characteristics of the populations we sampled interact with design features, that is, the same design prompted opposing behaviors in different groups. We conclude that it may be useful to examine goal-free and goal-oriented JME as separate constructs, that design choices influence the roles parents adopt during JME, and that the range of behaviors we observed complicate the prevailing research narrative of what positive and productive JME looks like.
China’s e-commerce is developing steadily towards intelligence, extension, standardization, division of labour, regionalization, popularization and internationalization. The competition of domestic e-commerce market has shifted from Tier 1-2 cities to tier 3-6 cities and to rural areas. Online e-commerce platform and offline stores begin to accelerate the industrial integration. This new retail mode will be close to consumers and provide operational efficiency. The technology of e-commerce development platform is also changing with each passing day. According to the idea of service-oriented, the system uses Dubbo, a distributed service framework based on Java, and uses zookeeper as the service registry to provide consistent coordination services for applications. Using the framework of Spring boot and the method provided by TkMybatis, the system realizes an e-commerce online shopping mall system with high concurrency, distribution and high availability e-commerce system - a comprehensive B2C shopping platform. In addition, the system also greatly reduces the coupling of the system, enhances the high availability, and has significant characteristics in maintainability and scalability.
With the development of Internet plus era and the increasing popularity of mobile phone in China, people still use the traditional finger touch mode. However, in the face of some application scenarios with high repetition frequency, an automatic control method can be built to reduce repetitive operation of users. This paper introduces how to solve the problem of automatic control process for Android operating system, and provides a complete solution for the design and construction of automation tools. Starting from the wake-up of the device, the system automatically unlocks, and then uses intent to transfer parameters to start the target application and specify the activity. After entering the specified application interface, the tool will scan the XML information of the interface layout drawn by the system, and accurately capture the view control through the regular matching of attribute values and other information of the control. Finally, the control object can be operated by simulating events, so as to achieve the same effect as the user operation. In addition, the automatic control tool obtains the control information accurately through OCR identification, and realizes the multithreading cycle operation through the delay start function, which improves the operation efficiency of the tool automation degree and the user operation efficiency of the smart phone.
Large-scale instruments sharing platform has been completed based on using Java language to program, and using spring Boot framework technology for building the background project, and using MySQL database to store the data, and using Vue to design the front-page, which will been shared and used in District, University and Enterprise. The test system of eclipse is used for case test to realize the sharing function of large-scale instruments. Through this platform, the instruments’ information and leasing of large-scale instruments can be understood in real time, and the status information, online use records, equipment using experience, and online booking, comments and customer service consultation can also be carried out on the platform, so as to make rational and efficient use of large-scale instruments, reduce the using waste of large-scale instruments, and be more conducive to the sustainable development of economy, science and technology and expand the scope of resource sharing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
