Mechanics of Rumor Mills and Epistemic Motivational Processes of Food-related Rumor Spread: Interplay between Attitude and Issue Motivation.

This study tested the manner in which attitude toward an object of rumor affects people's epistemic motivation to solve a problem and to share a rumor, specifically on social media, using two rumors regarding food safety issues including McDonald's and genetically modified food. An online survey administered to 184 undergraduate students who use Twitter showed that negative attitudes increased the likelihood of rumor sharing, mediated by issue-related epistemic motivation. However, positive attitudes showed no effects on issue-related motivation and the likelihood of rumor sharing.

Justificatory Information Forefending in Digital Age: Self-Sealing Informational Conviction of Risky Health Behavior.

This study proposes the idea of justificatory information forefending, a cognitive process by which individuals accept information that confirms their preexisting health beliefs, and reject information that is dissonant with their attitudes. In light of the sheer volume of often contradictory information related to health that is frequently highlighted by the traditional media, this study sought to identify antecedents and outcomes of this justificatory information forefending. Results indicate that individuals who are exposed to contradictory health information, currently engage in risky health behavior, are comfortable using the Internet to search for information, and are currently taking steps to maintain their health are likely to actively select health information that confirms their preexisting notions about their health, and to reject information that is contradictory to their beliefs.

Polymer Nanodot-Hybridized Alkyl Silicon Oxide Nanostructures for Organic Memory Transistors with Outstanding High-Temperature Operation Stability.

Organic memory devices (OMDs) are becoming more important as a core component in flexible electronics era because of their huge potentials for ultrathin, lightweight and flexible plastic memory modules.
