The results of calculations of semileptonic Bc meson exclusive decay channels using the quark potential model are presented. These results are compared with estimations made using the spectator model. The polarization of charmonia states resulting from b to c decay are also calculated, providing a more detailed experimental check of the model.

During the late 1990s, significant government-led policy debate in the UK on the tackling of social exclusion and the reduction of health inequalities produced a focus on the linkages which might exist between compound social exclusion, poor food retail access, compromised diets, and poor health in deprived urban neighbourhoods. Areas of poor access to the provision of healthy affordable food where the population is characterized by deprivation and compound social exclusion became known as food deserts (Beaumont et al, 1995; Dept of Health, 1996). It was a metaphor which caught the imagination of those involved in policy development, not least because it encouraged a shift in focus in health promotion activity (Lang and Caraher, 1998).
It soon became clear, however, that it was a metaphor which urgently needed ‘unpacking’ and subjecting to critical evidence-based assessment. In response, a number of major cross disciplinary investigations of food access and food poverty in British cities were funded by the research councils and government departments and are currently in progress. In this paper we report findings from one part of one of those studies specifically the first ‘before/after’ study of food consumption in a highly deprived area of a British city experiencing a sudden and significant change in its food retail access.
