A novel "raisin bun"-like nanocomposite, where Pd clusters are embedded in porphyrin matrix, is developed as a promising electrocatalyst. Thanks to the synergy between the Pd clusters and the porphyrin matrix, this composite exhibits a low oxidation potential, high mass activity and excellent stability toward electrochemical oxidation of formic acid, which opens new routes for the design of high-performance catalysts in fuel cells.
Judges tend to discount the opinions of others even though advice is often helpful in improving their accuracy. The present research proposes that this phenomenon of advice discounting results from the judges’ confidence in their initial decision and little trust in advice. Furthermore, the degree of advice discounting may be predicted by the combined roles of confidence and trust. Three studies provide evidence for these hypotheses. Participants were very confident in their initial estimation and had little trust in the advice (study 1). The degree of advice discounting decreased when participants felt less confidence in performing difficult tasks compared with easy tasks (study 2) or when participants placed more trust in advice because the advice was from an expert rather than from a novice (study 3). In addition, confidence and trust predicted the degree of advice discounting across three studies. These findings shed new light on the mechanism underlying advice discounting and advice taking by indicating the combined roles of confidence and trust.
Cooperation is vital for modern society. Previous studies showed that procedural fairness promotes cooperation; however, they mainly focused on cooperation intention, which may fail to reveal actual cooperative behaviour. Moreover, little is known regarding the personality boundary of the effect of procedural fairness on cooperation. Guided by previous findings that self‐esteem increases sensitivity to procedural unfairness, we attempted to explore the moderating effect of self‐esteem on the association between procedural fairness and cooperative behaviour. In Experiment 1, 160 participants' self‐esteem was measured using the Rosenberg Self‐Esteem Scale; procedural fairness was manipulated in two conditions, depending on whether money was allocated in an economic game by rolling the dice twice or an allocator's arbitrary choice. Cooperative behaviour was assessed using the chicken game paradigm. Experiment 2 (148 participants) aimed to replicate and extend the results of Experiment 1 using a more rigorous experimental design, in which the possible effect of outcome favourability was excluded. The results of both experiments consistently showed that procedural fairness positively predicted cooperative behaviour, and this association was significant in high‐self‐esteem individuals, but not in low‐self‐esteem individuals. These findings shed light on the vital role of self‐esteem in understanding the relationship between procedural fairness and cooperative behaviour.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
