Cross-cultural storytelling is a primary way for humankind to seek mutual recognition of value orientations between cultures,which facilitates the ability to jointly address the problems of human existence in the context of globalization.In this study,we conducted an interview survey of 6,130 respondents who were college students or graduates from 107 countries.The results show that there were a number of cross-cultural values embodied in China’s stories seen by the respondents as part of a common vision for the future of humankind and widely identified guidance on collaborative responses to global challenges.These cross-cultural values are common prosperity,ecological harmony,individual-collective integration,the urgency of global peace,as well as respect for multicultural and indigenous development paths. 展开更多

As socialism with Chinese characteristics enters a new era,ideological and political education in universities is presented with new opportunities.Telling the“Stories of China”is not only necessary for inheriting and promoting the excellent traditional Chinese culture but also an important way to build the socialist core value system and cultivate qualified builders of socialism.Effectively integrating the“Stories of China”with the ideological and political theory courses in universities is of great significance for guiding students to establish correct worldviews,outlooks on life,and values.This paper focuses on the practical paths of integrating the“Stories of China”with ideological and political theory in universities,deeply analyzes the existing integration mechanisms,principles to follow,and challenges faced,and explores innovative paths.It aims to provide a new perspective for ideological and political education in universities,promote the comprehensive development of students,and provide solid theoretical support for cultivating qualified socialist builders. 展开更多

While people from Western countries do not always understand of the underlying cultural values of most Chinese stories,the Hua Mulan story has gained significant recognition from Western audiences.Therefore,it would be quite beneficial if we could understand the key elements that have contributed to the success of the Hua Mulan story so that we can employ similar elements in other intercultural communication programs and promote the communication and dissemination of cultures between China and the rest of the world.According to the findings from the interviews of 6,130 respondents from 107 countries,we found that the Hua Mulan story gains global acceptance because it represents a story of“a hero with a thousand faces,”which embodies the integration of Chinese traditions and contemporary spirit through sharing a global meaning while responding to various culturally common challenges.Five key cultural value dimensions are responsible for this Chinese story’s cross-cultural affinity and influence,which helped it win recognition and empathy worldwide.The five key cultural value dimensions are loyalty and patriotism,the courage to take responsibility,compatibility of individualism and collectivism,respondence to the multicultural appeal,and hero growth.These dimensions are then generalized as the value identity orientation grounded in a Global Shared Meaning(GSM)in this study. 展开更多

In the existing ghost-imaging-based cryptographic key distribution(GCKD)protocols,the cryptographic keys need to be encoded by using many modulated patterns,which undoubtedly incurs long measurement time and huge memory consumption.Given this,based on snapshot compressive ghost imaging,a public network cryptographic key distribution protocol is proposed,where the cryptographic keys and joint authentication information are encrypted into several color block diagrams to guarantee security.It transforms the previous single-pixel sequential multiple measurements into multi-pixel single exposure measurements,significantly reducing sampling time and memory storage.Both simulation and experimental results demonstrate the feasibility of this protocol and its ability to detect illegal attacks.Therefore,it takes GCKD a big step closer to practical applications. 展开更多

We take phase modulation to create discrete phase-controlled sources and realize the super-bunching effect by a phasecorrelated method. From theoretical and numerical simulations, we find the space translation invariance of the bunching effect is a key point for the ghost imaging realization. Experimentally, we create the orderly phase-correlated discrete sources which can realize high-visibility second-order ghost imaging than the result with chaotic sources. Moreover, some factors affecting the visibility of ghost image are discussed in detail. 展开更多

This paper describes shaking table tests of three eight-story building models: all are masonry structures in the upper stories, with or without frame-shear walls of one- or two- stories at the bottom. The test results of damage characteristics and seismic responses are provided and compared. Then, nonlinear response analyses are conducted to examine the reliability of the dynamic analysis. Finally, many nonlinear response analyses are performed and it is concluded that for relatively hard sites under a certain lateral stiffness ratio (i.e., the ratio of the stiffness of the lowest upper masonry story to that of the frame- shear wall story), the masonry structure with one-story frame-shear wall at the bottom performs better than a structure built entirely of masonry, and a masonry structure with frame-shear wall of two stories performs better than with one-story frame- shear wall. In relatively soft soil conditions, all three structures have similar performane. In addition, some suggestions that could be helpful for design of masonry structures with ground story of frame-shear wall structure in seismic intensity region VII, such as the appropriate lateral stiffness ratio, shear force increase factor of the frame-shear wall story, and permissible maximum height of the building, are proposed. 展开更多

Purpose: Communicating scientific results to the public is essential to inspire future researchers and ensure that discoveries are exploited. News stories about research are a key communication pathway for this and have been manually monitored to assess the extent of press coverage of scholarship.Design/methodology/Approach: To make larger scale studies practical, this paper introduces an automatic method to extract citations from newspaper stories to large sets of academic journals. Curated ProQuest queries were used to search for citations to 9,639 Science and3,412 Social Science Web of Science(WoS) journals from eight UK daily newspapers during2006–2015. False matches were automatically filtered out by a new program, with 94% of the remaining stories meaningfully citing research.Findings: Most Science(95%) and Social Science(94%) journals were never cited by these newspapers. Half of the cited Science journals covered medical or health-related topics,whereas 43% of the Social Sciences journals were related to psychiatry or psychology. From the citing news stories, 60% described research extensively and 53% used multiple sources,but few commented on research quality.Research Limitations: The method has only been tested in English and from the ProQuest Newspapers database.Practical implications: Others can use the new method to systematically harvest press coverage of research.Originality/value: An automatic method was introduced and tested to extract citations from newspaper stories to large sets of academic journals. 展开更多
