Dark Triad and relational aggression: the mediating role of relative deprivation and hostile attribution bias.

Introduction: Relational aggression, as a distinct form of aggressive behavior in social relationships, is associated with various physiological and psychological disorders. Although previous research has provided theoretical support for the connection between the Dark Triad (Machiavellianism, psychopathy, and narcissism) and relational aggression, the mediating factors between the two still require in-depth exploration. This study employed a cross-sectional research method to examine the mediating roles of relative deprivation and hostile attribution bias between the Dark Triad and relational aggression.

C(60) reduces the flammability of polypropylene nanocomposites by in situ forming a gelled-ball network.

The thermal and flame retardancy properties of polypropylene/fullerene (PP/C(60)) nanocomposites were investigated by thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and cone calorimetry with the C(60) loading varied from 0.5 to 2% by weight. Dispersion of C(60) in the PP matrix was characterized by transmission electron microscopy (TEM) and optical microscopy (OM).
