The speech scripts and video excerpts from the subsequent manuscript collection with the CD-Rom published by FLTRP were studied. Lucas＇ framework of speech communication process was borrowed to bridge elements of the communication models and speech delivery process. Three key aspects of the speakers＇ encoding endeavors were under close examination： the verbal preferences, the non-verbal preferences, and the topic selection for exemplification. It was found that successful speakers demonstrated a clear and strong audience orientation. They chose more first person pronouns, fewer abstract words, a controlled number of dependent clauses, clear transition words, and limited figures of speech. They used very few verbal fillers, slips of tongue, a moderate speech rate and varied tone inflections. The speakers also showed distinctive features in gestures, eye contact and facial expressions. They employed anecdotes which shared a common field of experience. Pedagogical implications on the teaching of public speaking were discussed.展开更多

Typical SI includes fish schooling, ant foraging, bird migration, and so on. A great deal of models have been introduced to characterize the mechanism of SI. This article reviews several typical models and classifies them into four categories: self-driven particle models, with Boids model as the primary example;pheromone communication models, including the ant colony pheromone model which serves as the foundation for ant colony optimization;leadership decision models, utilizing the hierarchical dynamics model of pigeon flock as a prime instance;empirical research models, which employ the topological rule model of starling flock as a classic model. On this basis, each type of model is elaborated upon in terms of its typical model overview, applications, and model evaluation. More specifically, multi-agent swarm control, path optimization and obstacle avoidance, formation and consensus control, trajectory tracking in the dense crowd and social networks analysis are surveyed in the application of each category, respectively. Furthermore, the more precise and effective modeling techniques for leadership decision and empirical research models are described. Limitations and potential directions for further exploration in the study of SI are presented.展开更多

The study combines quantitative and qualitative approaches by using questionnaires and action research, to investigate how Chinese EFL and American CFL learners increase their intercultural communication competence by assessing their knowledge, awareness, attitudes, and skills of discovery and awareness. The findings reveal their changes and progress in the following variables: knowledge about the variety and subtlety of both the home and target cultures, a different worldview, and cultural study methods;awareness of the importance of differences and similarities between the home and target cultures, their negative reactions to these differences(e.g., fear, ridicule, disgust, feeling of superiority, etc.) and therefore, critical evaluation of the target and home cultures;attitudes from excitement or blind admiration of the target culture to confusion, anxiety or frustration about the cultural differences, later to toleration and appreciation of cultural differences, adaptation to the target culture, and eventually to openness and readiness to suspend disbelief about other cultures and belief about one’s own;skills to contrast the target culture with their own, to demonstrate a capacity to interact appropriately in a variety of different social situations in the target culture and resolve cross-cultural conflicts and misunderstandings. This research will serve as a valuable reference for computer-mediated intercultural communication teaching and open up new possibilities to extend classroom teaching by bridging the gap between second-hand knowledge and hands-on experience.展开更多

The globalization leaves its tracks in separate spheres of the educational system as well as it impacts all spheres of modern life. The relation between a teacher and a student differs with its peculiarity in the contemporary life. A pupil or a student differs totally in classifying the information gained in his activity. A modem student demonstrates a special attitude to everyday events and gets an independent position. Such reality demands the teacher of the day to have a very high practice; the necessity of contemporary training in the process of training-education can be marked as the appearance of globalization.

The 5G system is facing grand challenges such as the ever-increasing traffic volumes and remarkably diver- sified services connecting humans and machines alike. As a result, the future network has to deliver massively increased capacity, greater flexibility, incorporated computing capabili- ty, support of significantly extended battery lifetime, and ac- commodation of varying payloads with fast setup and low latency, etc. In particular, as 5G requires more spectrum resource, higher frequency bands are desirable. Nowadays, millimeter wave has been widely accepted as one of the main communication bands for 5G.展开更多

Methods: from November, 2018 to November, 2018, a total of 90 undergraduate nursing students from Affiliated Hospital of our hospital were selected for systematic communication training. SBAR communication model scale and cognitive questionnaire were used to investigate their application and cognition. Results: among 90 nursing students, 15 (16.7%) were excellent, 56 (62.2%) were good and 19 (21.1%) were qualified. SBAR communication mode has been recognized by most nursing students, and is willing to continue to use in the future work. Conclusion: SBAR communication mode has achieved satisfactory results in clinical practice of surgical nursing, which is worthy of promotion in clinical teaching.展开更多

In this paper, the architecture of Software Defined Space Optical Network (SDSON) based on cloud platform is designed by means of Software Defined Optical Network (SDON) and cloud services. The new architecture combining centralized and distributed management-control mechanism is a multi-layer and multi-domain architecture with powerful computing and storage ability. Moreover, reliable service and unreliable service communication models employed in the space information network are proposed considering the characteristic of Disruption/Delay Tolerant Network (DTN).

文摘The core goal of network security is to protect the security of data sharing.Traditional wireless network security technology is committed to guaranteeing end-to-end data transmission security.However,with the advancement of mobile networks,cloud computing,and Internet of Things,communication-computing integration and cloud-network integration have been important technical routes.As a result,the main application requirements of wireless networks have changed from data transmission to cloud-based information services.Traditional data transmission security technology cannot overcome the security requirements of cloud-network-end collaborative services in the new era,and secure semantic communication has become an important model.To address this issue,we propose a cloud-network-end collaborative security architecture.Firstly,we clarify security mechanisms for end system security,network connection security,and cloud services security,respectively.Next,based on the above three aspects,we elaborate on the connotation of cloud-network-end collaborative security.By giving example applications,including heterogeneous network secure convergence framework,unmanned system collaborative operations security framework,and space-air-ground integrated network security framework,we demonstrate the universality of the proposed architecture.Finally,we review the current research on end system security,network connection security,and cloud services security,respectively.
