Small tourism business entrepreneurs (STBEs) are important stakeholders in rural destinations, so that their community citizenship behavior for the environment (CCBE) greatly influences the sustainable development of rural tourism communities. This paper thus focuses on STBEs’ CCBE. Guided by equity theory and social exchange theory, this article examines the impact of perceived justice on CCBE and the mediating roles of place identity and subjective well-being in that process. The survey data was collected from 434 STBEs in rural China. Results indicate that perceived justice positively relates to place identity and subjective wellbeing. Furthermore, place identity and subjective well-being fully mediate the effect of perceived justice on CCBE. These findings offer a newer understanding of the underlying mechanism between perceived justice and CCBE and offer implications for destination managers to promote sustainable development of rural destinations.

Molecular dynamics simulation was applied to investigate the metabolism mechanism for quinone analogues. Favourable hydrogen bonds between ligand and NQO1, and parallel orientation between ligand and flavin adenine dinucleotide could explain the difference of metabolism rate (in μmol/min/mg) for quinone analogues. This is consistent with the experimental observation ( Structure 2001;9:659–667). Then Support Vector Machines was used to construct quantitative structure–metabolism rate model. The model was evaluated by 14 test set compounds. Some descriptors selected by Support Vector Machine, were introduced into standard fields of three-dimensional quantitative structure–metabolism relationship to improve the statistical parameters of three-dimensional quantitative structure–metabolism relationship models. The results show that the inclusion of highest occupied molecular orbital and lowest unoccupied molecular orbital is meaningful for three-dimensional quantitative structure–metabolism relationship models. These in silico absorption, distribution, metabolism and excretion models are helpful in making quantitative prediction of their metabolic rates for new lead compounds before resorting in vitro and in vivo experimentation.
