Predictors of parental involvement activities in sport

The purpose of this research is to examine the utility of a theoretical model to predict parental involvement activities in children’s sport. Participants included 486 parents of young athletes of various sports, subdivided in two studies (n1 = 206, n2 = 280). Confirmatory factor analysis (CFA) conducted in Study 1 supported the proposed measurement model. All factors also show reliability, convergent and discriminant validity. In the Study 2, a structural equation model demonstrated that the parental role beliefs, parental self-efficacy, perceptions of child invitations, selfperceived time and energy, and knowledge and skills predicted parents’ home-based involvement. Perceptions of coach invitations were a significant negative predictor. These same constructs, with the exception of perceptions of knowledge and skills and perceptions of coach invitations, predicted parents’ club-based involvement. Multi-group analysis demonstrated the invariance of the model. Findings suggest that this model offers a useful framework to understand parents’ home and clubbased involvement.

Development of antibacterial ZnO-loaded cotton fabric based on in situ fabrication

A method provided for the deposition of nanostructured ZnO on cotton fabric to introduce antibacterial functionality was presented in this article. This strategy enabled fabric to be coated with inorganic-based functional materials through in situ synthesis of nanoparticles using ultrasonic irradiation. The amino-terminated silicon sol (AEAPTS) was employed to generate nanostructured ZnO, and the mechanism of the ultrasound-assisted coating was proposed. Antibacterial activities, UV protection and other properties of ZnO-loaded cotton characterized by SEM, FTIR, XRD and TGA were investigated. The results indicated that ZnO-loaded cotton exhibited excellent UV protective property, efficient antibacterial activities, well water-resistant effect, together with moderate cytotoxicity against L929 and lower tensile strength. The developed method provides not only a facile way for in situ synthesis of ZnO on textile but also the production of antibacterial materials for healthcare applications.
