Understanding Urban Cultural Festivals As Social Infrastructure, Bernadette Quinn Jan 2025

Understanding Urban Cultural Festivals As Social Infrastructure, Bernadette Quinn

Research Outputs: 2025-Present

This paper is concerned with the role that urban cultural festivals play in enhancing the quality and vitality of social life. It acknowledges that their reputation has become tarnished in recent years and that festivals now frequently feature in debates because they are charged with inciting tensions, exclusions and contestations. However, of note here is that cities tend to narrowly conceive of festivals as temporarily bounded moments of commodifiable spectacle. The fact that festivals function, on an ongoing manner, as embedded, sustained practices capable of supporting urban social living in numerous ordinary ways is rarely acknowledged, much less prioritised. This …

Research Outputs: 2025-Present

Bimanes, a class of molecules based on the 1H,7H-pyrazolo[1,2-a]pyrazole-1,7-dione scaffold, were first introduced by E. M. Kosower in 1978. In this study, we report the topochemical cycloaddition of diethyl 2,6-dichloro-1,7-dioxo-1H,7H-pyrazolo[1,2-a]pyrazole-3,5-dicarboxylate (Cl2B), initiated by visible light. Crystal structure analysis confirmed that the reactive double bonds are parallel and coplanar, in line with the Schmidt criteria for topochemical cycloaddition. Additionally, two other bimane derivatives with different substitution patterns were synthesized and investigated. Our findings suggest that functionalizing bimanes to redshift their absorption maxima into the visible-light spectrum provides a promising strategy for synthesizing substituted cyclobutanes without the need for ultraviolet …
