The protective effect of psychological suzhi on the relationship between school climate and alcohol use among Chinese adolescents.

Background: There issome research on school climate impact on adolescent alcohol use in the Western social context; however, there is no research on school climate impact on adolescent alcohol use in China. This study aimed to explore the effect of school climate on Chinese adolescents' alcohol use, and the moderating role of psychological suzhi between them. Methods: A total of 801 adolescents (45.8% boys, 14.96±1.66 years) completed self-reports on school climate, psychological suzhi, and alcohol use. Results: Moderation analyses revealed that both school climate and psychological suzhi significantly negatively predicted adolescents' alcohol use, and the interaction of school climate and psychological suzhi significantly positively predicted adolescents' alcohol use. Moreover, the effect of school climate on adolescents' alcohol use was stronger for low psychological suzhi adolescents than high psychological suzhi adolescents. Conclusions: We can build good school climate by formulating of national level legal and regulations and good social norms, and use mature interventions or cultivation strategies to improve adolescents' psychological suzhi in order to better play its role in protection.

Assembly of a series of coordination polymers built from rigid a tetracarboxylate ligand and flexible bis(imidazole) linker: syntheses, structural diversities, luminescence sensing, and photocatalytic properties.

Hydrothermal reactions of aromatic terphenyl-4,2'',5'',4'-tetracarboxylic acid (H4tta) and transitional metal cations in the presence of two flexible N-donor ancillary ligands afforded four novel coordination polymers, namely, {[Zn(tta)0.5(m-bimb)]·H2O}n (1), [Ni2(tta)(m-bimb)2(H2O)]n (2), [Ni(H2tta)(o-bimb)·H2O]n (3), and [Cd(tta)0.5(o-bimb)]n (4), from solvothermal reactions in the presence of bis(imidazole) bridging linkers (m-bimb = 1,3-bis(imidazol-1-ylmethyl)benzene, and o-bimb = 1,2-bis(imidazol-1-ylmethyl)benzene). Their structures were determined by single-crystal X-ray diffraction analyses and further characterized by elemental analyses (EA), powder X-ray diffraction (PXRD), and thermogravimetric (TG) analyses. Compound 1 displayed a 2-fold 3D → 3D parallel entangled (4,4)-connected bbf net with the point symbol of (64·82)(66)2. Compound 2 featured a predocumented 3D (4,8)-connected (32·53·6)(34·44·59·611) net. Compound 3 exhibited a 2D 4-connected sql sheet with the point symbol of (44·62), and compound 4 showed a 2D 4-connected (32·62·72) kgm sheet. To our delight, fluorescence measurements showed that compound 1 could selectively and sensitively detect Cr3+ cations and nitrobenzene derivatives (nitrobenzene (NB), p-nitrotoluene (PNT), and p-nitroaniline (PNA)), which suggested that CPs of 1 was a promising bifunctional luminescence sensor material that could sense metal ions and small organic molecules. Moreover, 1 showed excellent photocatalytic activity.
