Since its implementation in 2013, China has ushered in a significant change in communication ideas and approaches. This strategy also enriches the communication genres of "China's stories" and more importantly enhances its communication effect. In this context, it is necessary to understand and study the significance of this strategic practice, assess the value realization of "China's stories" during the communication process, and thereby establish a basis for future communication of more "China's stories." Based on the factors of relevance theory, this paper analyzes the ideas of and approaches to effective communication of "China's stories" and proposes corresponding strategies.展开更多

Employing a rigorous mixed-methods approach, we conduct an in-depth analysis of the effects of AI-driven personalization on audience engagement, brand perception, and conversion rates across various industries and communication channels. Our findings reveal that while AI-powered personalization significantly enhances communication effectiveness and offers unprecedented opportunities for audience connection, it also raises critical ethical considerations and implementation challenges. The study contributes substantially to the growing body of literature on AI in communications, offering both theoretical insights and practical guidelines for professionals navigating this rapidly evolving landscape. Furthermore, we propose a novel framework for ethical AI implementation in strategic communications and outline a robust agenda for future research in this dynamic field.展开更多

The contact, in different domains between English and indigenous languages in the country continues to affect performance in English and contact languages, making effective communication in either English or any of the indigenous languages unattainable. The purpose of this study is to show that although no particular document, so named, exists expressing the nation＇s policy on language, nonetheless, the country has a policy on language that accommodates the indigenous languages as substrates, while the English language holds sway in various linguistic domains. Using a simple descriptive survey with data from previous studies, this paper examines the linguistic implications of the contact between English and indigenous languages on the younger generations who are losing contact with the mother tongue, and also not demonstrating enough proficiency in the English language. It is recommended that the opportunities that competence and maturation afforded a second language learner should be latched onto to gain the needed proficiency in English thus making them effective bilinguals and communicators in a world that is fast becoming a global village, and the inhabitants global citizens.展开更多

The aim of the study was to review the literature on how good communication might improve treatment outcomes for Kenyan patients with chronic and terminal illnesses and to determine whether Cybernetic electronic communication can improve those outcomes even more. We uncovered the history of treatment outcomes for chronic and terminal diseases in this research study, both with and without communication at the core of the patient’s care plan. We discussed the importance of good communication in the treatment of patients with chronic and terminal illnesses and why it is a momentous endeavor comparable to medical diagnosis and treatment for the long-term health of patients. To locate pertinent material for the background literature study, we carried out a comprehensive literature search. Although the preliminary literature review was a continuation of the introduction research, it also highlighted the paucity of local Kenyan literature and suggested that improved communication might help patients with chronic and terminal illnesses have better treatment outcome. Methodology maintained the literature search, as a systematic literature review focused on core of the study, making separate sections of the same body necessary. This ensured that a methodological literature search section is as comprehensive as possible. We used an integrated PRISM model to limit a comprehensive literature search and a systematic literature review design as part of the overall process. Non-probability sampling and snowball approaches on literary papers over the previous 17 years were used in this arrangement. Since this was a multidisciplinary study, the four experts who also serve as authors were chosen from within their respective fields of expertise to design the study. They created search strategies, generated key words, looked up keywords in database engines, assessed the results of the literature using the PRISMA logical model, looked over successful literature, and triangulated their findings. The conclusions of the experts individually revealed a convergence of thoughts, beliefs, and practices across. The study concluded that even though there isn’t much research done in Kenya on the same subject;what is available illustrates how crucial good communication is for patients with chronic illnesses. The study’s findings also highlighted the positive effects of effective communication between patients and healthcare professionals on treatment plan adherence, patient satisfaction, and overall health outcomes. The results also noted that in order to improve patient care and outcome, Kenyan healthcare workers should underscore developing their communication skills. The study also found that the incorporation of cybernetics is crucial if a truly effective communication is required so as to enable centered care for patients with long-term diseases in Kenya. The goal of the Cybernetics is to activate genuinely effective communication in the care of Patients with long-term disease in Kenya. This study is organized to begin with an abstract, followed by keywords, an introduction, literature review, methodology, findings, discussion, and finally conclusions.展开更多

This study is one of the few studies concerning scientific research groups in China. In 2018, our research team surveyed the public-oriented science communication activities of 601scientific research groups in China using questionnaires. The survey shows that Chinese scientific research groups are active in promoting science to the public, and that related work structure and guarantee mechanisms have been established and have already produced some social benefits. However, there remain challenges, including limited channels for science communication, insufficient collaboration among the participants in the communication process and unbalanced investment. Based on an analysis of the survey results, we put forward several suggestions on how to encourage scientific research groups of universities and research institutions to engage in public-oriented science communication activities.展开更多

FSOIs use lasers in board-to-board and rack-to-rack communication to achieve improved performance in next generation servers and are expected to help meet the growing demand for massive amounts of inter-card data communication. An array of transmitters and receivers arranged to create an optical bus for inter-card and card-to-backplane communication could be the solution. However, both chip heating and cooling fans produce temperature gradients and hot air flow that results in air turbulence inside the server, which induces signal fading and, hence, influences the communication performance. In addition, the proximity between neighboring transmitters and receivers in the array leads to crosstalk in the received signal, which further contributes to signal degradation. In this Letter, the primary objective is to experimentally examine the off-axis crosstalk between links in the presence of turbulence inside a server chassis. The effects of geometrical and inter-chassis turbulence characteristics are investigated and first-and second-order statistics are derived.展开更多
