In the 1970s, Michael Manley set out a vision of democratic socialism that was internationalist, anti-imperialist, and centred on the needs of poor and working-class people. Manley also recognised that [...]

Symmetry-forming closest approaches of aromatic rings; 'Symthons', are usually the strongest interactions in halobenzene crystal structures. Where they combine to create π–π stacking, they are as strong as hydrogen bonds. This π–π stacking is disrupted when fluorine is present, as revealed in this analysis of all 290 closest aromatic approaches in the crystal structures of halobenzenes. Closest aromatic approaches involving fluorine show fewer examples of 'Symthon I' π–π stacking, and more examples of offset translations with larger displacements. Edge⋯face approaches are also more common in the presence of fluorine, frequently accommodating fluorine atoms in the 'edges'. Some edge⋯face approaches do not embody any symmetry. These findings are consistent with lower melting points and favourable connections between fluorine and positively charged carbon atoms. [ABSTRACT FROM AUTHOR]

Resumen En este artículo se investiga la contribución de las organizaciones de trabajadores domésticos al control del cumplimiento de la legislación laboral. Se examina cualitativamente el caso del Sindicato de Trabajadores Domésticos de Jamaica tras la ratificación del Convenio sobre las trabajadoras y los trabajadores domésticos, 2011 (núm. 189) por este país. Se constata que el sindicato participa directa e indirectamente en los procesos de control. El enfoque participativo centrado en los trabajadores no sustituye a los mecanismos estatales, pero puede contribuir a la observancia en el sector y sugiere que la voz y la representación colectiva de los trabajadores son esenciales para cumplir las expectativas del convenio.
