ABSTRACT

This article analyses the limits of ECOWAS’ top-down approach to mediation, based on a case study from Burkina Faso in 2014 and 2015. It shows the growing importance of ordinary citizens in the regulation of political arenas, both at the domestic and the regional level, as well as citizens’ impact on ECOWAS mediation in Burkina Faso. It thereby argues that mediation in ‘revolutionary’ situations is hardly feasible. In Burkina Faso, the 2014 popular uprising created a new kind of citizenry who felt ‘sovereign’ and expressed its grievances through mass mobilisations. In such political contexts, regional mediation, which aims at re-establishing stability and power-sharing agreements, becomes problematic because it contradicts the spirit ‘from the streets’. Moreover, the top-down approach also erodes the legitimacy of the mediators, who are perceived to work against ‘the people’s will’. The reflection draws attention to the tensions between international mediators and actors from below and highlights the need to craft new strategies for conducting mediation in the context of popular uprisings.  相似文献

A number of N‐substituted piperazines have been described as drugs of abuse in recent years. This new drug category includes several series of aromatic ring substituted phenylpiperazines. The wide variety of available precursors makes regioisomerism a significant issue in these totally synthetic compounds. In this study, a complete series of regioisomeric dimethoxyphenylpiperazines were synthesized and evaluated using GC‐MS and FT‐IR. The EI mass spectra show fragments characteristic of both the dimethoxyphenyl and the piperazine portions of the molecules including the dimethoxyphenylaziridinium cation (m/z 180) and dimethoxyphenyl cation (m/z 137). The ion at m/z 56 for the C3H6N+ fragment is characteristic of the piperazine ring and was observed in all the spectra. The perfluoroacyl derivatives were resolved by GC, and their mass spectra showed some differences in relative abundance of ions. FTIR provides direct confirmatory data for differentiation between the regioisomeric dimethoxyphenylpiperazines, and GC separation was accomplished on an Rtx‐200 phase.  相似文献
