With the rapid development of e-commerce technology, cross-channel consumption has become the mainstream mode of contemporary consumers. However, there are several problems of cross-channel consumption such as inconsistency of online and offline channel information and service, disfluency of channel switching which have brought adverse effects on user experience. The question arises here as to what factors influence user experience and how to build a scientific and effective evaluation index system. Different from previous studies based on sellers, this paper used grounded theory to analyze and summarize the evaluation index system of user experience under cross-channel consumption from the perspective of consumers. We summarized and refined four first level indexes which are “online platform attribute, offline entity attribute, channel switching attribute, and individual demand” and 13 second level indexes which are “platform operation, platform information, platform service, platform promotion, product quality, service quality, environment quality, channel consistency, channel switching cost, channel switching fluency, psychological expectation, personal interests and individual needs.” Then, we used BP neural network to build the evaluation model and trained and simulated the performance of the sample. The results show that the evaluation model has a good generalization ability and can effectively evaluate user experience under cross-channel consumption. Finally, implications and limitations are also discussed. This study helps to enrich the theoretical research on user experience and consumer behavior. It also provides targeted basis for in-depth analysis of cross-channel consumption behavior, establishment of user experience evaluation index system, and improving user experience and multichannel management of physical stores.

With the change of health concept and medical mode, the nursing personnel in the 21st century will confront day by day expanding work domain, and new opportunities and challenges put forward new requirements for the scale and quality of nursing personnel training. The core problem of nursing education reform is course reform. At present, nursing specialty teaching has such problems as the lack of learning initiative and imperfect course evaluation system which seriously affect the teaching effect. Hence, this study applied UCD theory, summarized the principles of multimedia teaching design based on UCD theory, and applied it in network course design of nursing teaching. The detailed design application method expanded in detail from three aspects: course process, course content and course experience. Meanwhile, four-in-one (blended-flipped-autonomous-collaborative) teaching model was proposed. The teaching model is based on the functional structure relation between course objective and course implementation process, and element analysis model of course quality process. The course quality evaluation index system oriented to objective-process was constructed from six dimensions (including course objective adaptation, teaching resource guarantee, teaching program execution, teaching program suitability, quality assurance effectiveness and course objective attainment) to assess the application effect of four-in-one teaching model in Fundamental Nursing. The results show that the four-in-one teaching model better improves students’ self-management ability, information acquisition ability, learning and cooperation ability, compared with traditional teaching models. Objective-process course quality evaluation index system can quantify evaluation of teaching effect from multiple dimensions and make teachers optimize course design with pertinence.

Effectiveness evaluations are one of the important ways to guide grid investment and to improve investment efficiency. Improving the effectiveness of grid investment evaluations is studied based on the optimization of the investment evaluation index system and the utility evaluation model. The index system is optimized by establishing an evaluation index system of grid investment effectiveness, considering the redundancy between the indices, and constructing an ISM-DEA model. The utility function model was introduced to fully consider the different risk appetites of decision-makers, and a utility evaluation model that takes risk appetite into account was established. An improved weight integration model based on multiobjective optimization was established by considering the minimum deviation and the trend-optimal objective function when setting the index weights. The calculation results show that the feasibility of the index system optimization model and utility evaluation model constructed in this study is verified under the premise of satisfying the assumptions. By adjusting the risk preference coefficient of decision-makers, the dynamic optimization of the grid investment utility evaluation results can be realized.
