This study presents an empirical test and a conceptual account of the role of within-border foreign publics (WBFPs) as important communicative influencers, explicating how shared experiences shape the ideas and opinions of a foreign country. The study focuses on two communicative concepts, megaphoning and echoing, and finds they explicate network impacts of sociological public diplomacy. The information megaphoned by the WBFP (e.g., international students) is echoed in their relational networks back home. The findings provide evidence that the megaphoning behaviors of WBFPs are significantly related to the directionality and magnitude of echoing among their social networks in their home countries.

拥护者还是反对者？通过扩音和呼应，阐释境内外国公众在塑造软实力中的作用

本研究对境内外国公众 (WBFP) 作为重要的交流影响者的作用进行了实证检验和概念说明，解释了共享经验如何塑造外国的想法和观点。该研究侧重于两个交际概念，扩音器和回声，并发现它们解释了社会学公共外交的网络影响。WBFP（例如，国际学生）通过扩音器传播的信息在他们国内的关系网络中得到回响。调查结果提供证据表明，WBFP 的扩音行为与其本国社交网络之间的回声的方向性和幅度显着相关。
