Between tradition and change: the Scottish social economy sector at a crossroad

This paper discusses the origins and motives behind the rich institutional and policy infrastructure that Scotland has developed in previous decades to support the social economy sector. Drawing on a large body of primary data collected through an EU funded project this paper reflects upon the effects of the economic and financial crisis, and how such changes may shed light on the future of the social economy in Scotland

An investigation on the mechanics of homogeneous expansion in gas-fluidized beds

The Richardson and Zaki (1954, Sedimentation and fluidization. Trans. Inst. Chem. Eng. 32, pp. 35–53.) equation has been used extensively to investigate the expansion profiles of homogeneous gas-fluidized beds. The experimental value of the parameter n appearing in the equation indicates how significantly interparticle forces affect the expansion of these beds, revealing the relative importance of these forces with respect to the fluid dynamic ones. In this work, we modeled the stable expansion of gas-fluidized beds of different diameter, accounting for enduring contacts among particles and wall effects. We solved the model numerically to obtain the bed expansion profiles, back-calculating from them the values of the parameter n. For all the cases considered, we observed that the values of n are higher than those obtained by purely fluid dynamic correlations, such as those advanced by Richardson and Zaki, and Rowe (1987, A convenient empirical equation for estimation of the Richardson and Zaki exponent. Chem. Eng. Sci. 42, pp. 2795.). This effect was more pronounced in beds of smaller diameter. To validate our model, we carried out fluidization and defluidization experiments, analyzing the results by means of the Richardson and Zaki equation. We obtained a reasonable agreement between numerical and experimental findings; this suggests that enduring contacts among particles, which are manifestations of cohesiveness, affect homogeneous bed expansion. This effect is amplified by wall friction

Self reliant groups from India to Scotland: lessons from south to north

There is a move towards partnership working across the global north and south but there remain questions about how to do it most effectively. This paper reports on the findings from a project that built a partnership between women in Scotland and India in order to transfer knowledge about Indian Self Help Groups. By creating peer to peer relationships that challenged traditional roles of 'teacher' and 'learner', the project was effective in transferring learning from south to north and generating meaningful outcomes for those involved. Despite the contextual differences, the successful transfer of key components of the model, savings, and loans, has led to a sense of empowerment in the Scottish women that is comparable to their Indian counterparts. As the project continues, it will be important that the dialogue between the partners continues, so there is ongoing learning as the Scottish groups expand and develop
