Getting off the escalator? A study of Scots out-migration from a global city region

Something new is happening to reverse the historical trend of skilled Scots moving to London for career progression. The Scottish population of London and the South East is falling and this despite Scots enjoying continued occupational success within the South East labour market. The authors ask why Scots are leaving the UK's main escalator region and then investigate how these migration changes can best be theorised relative to literature on the mobility of the 'new service class'. Building on Fielding's escalator region hypothesis, the authors report on recent research on longer distance flows out of the UK's main escalator region. They advance the critique of the escalator region hypothesis set out by Findlay et al and ask why people would leave a global city offering good opportunities for occupational mobility. Demographic regime change provides only a partial answer. Other explanations can be found in the changing mobilities of the new service class as they engage in what Smith has defined as 'translocal' and 'transnational' urbanism. The authors argue that Scotland's changing relationship with London and the South East may be representative of a wider set of changes in migration linkages between regional economies and global cities.

Pre-Retirement Age Migration to Remote Rural Areas

Recent literature suggests that the increasingly blurred relationship between paid employment and retirement facilitates a retirement transition period, a life course stage, which may involve a change of residence. The role of such pre-retirement age mobility in the repopulation of rural areas has, however, received relatively little academic scrutiny. This paper draws upon findings from a two-year study conducted in three UK case study areas. It examines the extent of pre-retirement age (aged 50–64) migration into remote rural communities and the impacts this type of movement has upon economic activity, social and community engagement and service provision. It is argued that while this under-researched cohort offers opportunities to support the social and economic sustainability of rural communities (at least in the short and medium term), there are notable challenges which are likely to emerge as it ages in situ. The findings are particularly relevant given national trends on population ageing.

Retirement Transition Migration: Implications for Rural Development

Recent literature suggests that the increasingly blurred relationship between paid employment and retirement facilitates a retirement transition period, a life course stage which may involve a change of residence. The role of pre-retirement mobility in the repopulation of rural areas has, however, received relatively little academic scrutiny from UK geographers. This article draws upon findings from a two-year study conducted in three UK case study areas. It examines the extent of pre-retirement age (aged 50-64) migration into rural communities and the impacts this type of movement has upon economic activity, social and community engagement and service provision. It is argued that while this under-researched group offers significant potential to support the social and economic sustainability of rural communities (at least in the short and medium term), there are notable regional variations which are likely to have important long term implications for rural communities as this cohort ages in situ.

Influence of service loading and the resulting micro-cracks on chloride resistance of concrete

Chloride-induced corrosion of steel in reinforced concrete structures is one of the main problems affecting their durability, but most previous research projects and case studies have focused on concretes without cracks or not subjected to any structural load. Although it has been recognised that structural cracks do influence the chloride transport and chloride induced corrosion in reinforced concrete structures, there is little published work on the influence of micro-cracks due to service loads on these properties. Therefore the effect of micro-cracks caused by loading on chloride transport into concrete was studied. Four different stress levels (0%, 25%, 50% and 75% of the stress at ultimate load – fu) were applied to 100 mm diameter concrete discs and chloride migration was measured using a bespoke test setup based on the NT BUILD 492 test. The effects of replacing Portland cement CEMI by ground granulated blast-furnace slag (GGBS), pulverised fuel ash (PFA) and silica fume (SF) on chloride transport in concrete under sustained loading were studied. The results have indicated that chloride migration coefficients changed little when the stress level was below 50% of the fu; however, it is desirable to keep concrete stress less than 25% fu if this is practical. The effect of removing the load on the change of chloride migration coefficient was also studied. A recovery of around 50% of the increased chloride migration coefficient was found in the case of concretes subjected to 75% of the fu when the load was removed.
