Bearing Witness to the 'Pain of Others': Researching Power, Violence and Resistance in a Women's Prison

Addressing the dynamics of interpersonal violence, institutionalised abuses and prisoner isolation, this article consolidates critical analyses as challenges to the essentially liberal constructions and interpretations of prisoner agency and penal reformism. Grounded in long-term research with women in prison in the North of Ireland, it connects embedded, punitive responses that undermine women prisoners’ self-esteem and mental health to the brutalising manifestations of formal and informal punishments, including lockdowns and isolation. It argues that critical social research into penal policy and prison regimes has a moral duty, an ethical obligation and a political responsibility to investigate abuses of power, seek out the ‘view from below’. Challenging the revisionism implicit within the ‘healthy prison’ discourse, it argues for alternatives to prison as the foundation of decarceration and abolition.

The dichotomy in the DNA-binding behaviour of ruthenium(II) complexes bearing benzoxazole and benzothiazole groups

The substituted tris(bipyridine)ruthenium(II) complexes {[Ru(bpy)(2)(4,4'-bbob)](2+) and [Ru(bpy)(2)(5,5'-bbob)](2+) [where bpy = 2,2'-bipyridine and bbob = bis(benzoxazol-2-yl)-2,2'-bipyridine] have been prepared and compared to the previously studied complex [Ru(bpy)(2)(4,4'-bbtb)](2+) [where bbtb = bis(benzothiazol-2-yl)-2,2'-bipyridine]. From the UV/VIS titration studies, Delta-[Ru(bpy)(2)(4,4'bbob)](2+) displays a stronger association than the Lambda-isomer with calf-thymus DNA (ct-DNA). For [Ru(bpy)(2)(5,5'-bbob)](2+), there appears to be minimal interaction with ct-DNA. The results of fluorescence titration studies suggest that [Ru(bpy)(2)(4,4'-bbob)](2+) gives an increase in emission intensity with increasing ct-DNA concentrations, with an enantiopreference for the A isomer, confirmed by membrane dialysis studies. The fluorescent intercalation displacement studies revealed that [Ru(bpy)(2)(4,4'-bbob)](2+) and [Ru.(bpy)(2)(5,5'bbob)](2+) display a preference for more open DNA structures such as bulge and hairpin sequences. While Delta-[Ru(bpy)(2)(4,4'-bbtb)](2+) has shown the most significant affinity for all the oligonucleotides sequences screened in previous studies, it is the A isomer of the comparable benzoxazole ruthenium(II) complex (Delta-[Ru(bpy)(2)(4,4'-bbob)](2+)) that preferentially binds to DNA.
