Direct and Indirect Effects of Involvement on Hostile Media Perceptions in the Context of the Refugee Crisis in Germany and Switzerland

This article examines hostile media perceptions (HMPs) by building on recent trends in hostile media research. Our study considers the effects of people’s cognitive as well as their affective involvement on HMPs. As the media landscape has changed fundamentally since HMPs were initially identified, the role of social media is explored more profoundly. In addition, this article not only examines the direct effects of involvement and communication activities but tests for indirect effects of involvement mediated through media use and interpersonal discussions. Using data simultaneously collected from two online surveys conducted in Germany and the German-speaking part of Switzerland, the findings strengthen previous evidence that affective involvement is a stronger predictor of HMPs than cognitive involvement. In contrast, media use and interpersonal discussions had only marginal direct effects. The study provides initial evidence for the indirect effects of involvement mediated through exposure to online user comments and interpersonal discussions.     

Preparation of carbon encapsulated iron nanoparticles with very thin shells by DC arc discharge

Carbon encapsulated iron nanoparticles(CEINPs) with very thin shells and good core-shell structures were prepared by DC arc discharge at argon intake temperature(AIT) of 800 ℃. The results of high resolution transmission electron microscope(HRTEM), energy dispersive X-ray(EDX) spectroscope, X-ray diffraction(XRD), and X-ray photoelectron spectroscope(XPS) characterizations on the product B show that the thickness of the carbon shells of CEINPs in the product B is in the range of ca. 0.5—5.3 nm, i. e., which can be as thin as only two layers of graphite. The average diameter of the CEINPs is about 24. 7 nm. The total content of Fe element in the product B is 77.0 wt%. The saturation magnetization(Ms) and coercivity(Hc) of the product B are 107.4 emu/g and 143 Oe, respectively. The formation of the CEINPs in the product B is discussed briefly.
