Building on extant literature in crisis communication and rhetorical strategies for persuasion, the current study examined the efficacy of a refutation appealing to rationality in mitigating the negative effects from an activist’s accusation of which validity can be contentious. In a posttest-only control group design, participants in either of two experimental conditions or a control condition evaluated a government’s refutation message appealing to either logos or pathos or a “no comment” response respectively and indicated their attitude, perceived credibility and trust toward the organization. Results indicate that a refutation appealing to logos generated more positive evaluations than a refutation showing indignation in the message evaluations of transparency and reliability. In addition, a refutation appealing to logos generated more positive attitude, greater perceived credibility and trust toward the organization than a refutation appealing to pathos and a “no comment” response.

Axial cyclone was designed to collect iron oxide rear the heat recovery steam generator. In this study, we used the numerical method to estimate the fluid characteristics and particle dynamics in axial cyclone with conical tube which enhanced the swirl flow for higher collection efficiency. As a result, particle density increased near the wall which to particle absorbed and swirl number increased.
