The Relationship

Abstract A systematic scoping review of anti-smoking mass media campaign literature provided opportunity to explore how social normative theories and constructs are used to influence smoking cessation. Synthesis of findings was constrained by significant heterogeneity. Nevertheless, the results indicate that a broader conceptualization of social norm is worthy of further exploration. Perceptions of what others think and do contributed in multiple ways to the relationship between anti-smoking messaging and quitting outcomes. Furthermore, integrating research on social norms, social identity and communication may improve understanding of why quitting intentions are enhanced in some circumstances but reactance and counter-arguing responses corresponding to lower quitting intentions occur in others. Integrating a broader theoretical understanding of normative influences into campaign development and evaluation may prove useful in demonstrating the effectiveness of this approach in behaviour change campaigns.

The Relationship

The relationship between social movements and the legal field is controversial and complex. This paper begins by recognizing that the concept of social movement does not belong to legal doctrine and then synthetically reconstruct the relevance of it for a legal understanding. In fact, even if this concept is not formally taken into account by constitutions or by legal codes, a socio-legal approach underscores the need for the comprehension and inclusion of collective phenomena into legal theory. First, the paper explores the way in which ‘social movement’ has been taken up and translated in the legal field through the concept of social change and constitutional change. Second, this research goes through various cases in which social movements use law strategically, from the phenomenon of cause lawyering to the litigation strategy. Finally, it stands for a theoretical understanding of the role of social movements in legal theory as a lively expression of ‘becoming-constituent’.

By facilely pre-implanting Co[Formula: see text] ions in the graphene oxide, a novel 5,15-diphenyl-10,20-di(4-pyridyl)porphyrin pillared graphene oxide was fabricated by means of electrostatic interaction and coordination interaction. It was shown that the morphology and the structure of graphene oxide and pyridylporphyrin nanocomposite were modified by introducing Co[Formula: see text] ions on the interface between graphene oxide and pyridylporphyrin. Furthermore, it was found that the photocatalytic hydrogen evolution activity over the Co[Formula: see text] ions implanted in the graphene oxide and pyridylporphyrin nanocomposite was evidently higher than in the graphene oxide and pyridylporphyrin nanocomposite without Co[Formula: see text]. This confirmed that strong interaction and efficient electron transfer between pyridylporphyrin and graphene oxide are the important reasons for the enhanced photocatalytic activity for hydrogen evolution. Subsequently, this technique will be a simple and efficient approach to optimize the transfer pathway of photogenerated electrons and to improve photocatalytic performance by implanting metal ions in the interface of nanocomposites.
