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.

Generation and optimization of electron currents along the walls of a conical target for fast ignition

The interaction of an ultraintense laser pulse with a conical target is studied by means of numerical particle-in-cell simulations in the context of fast ignition. The divergence of the fast electron beam generated at the tip of the cone has been shown to be a crucial parameter for the efficient coupling of the ignition laser pulse to the precompressed fusion pellet. In this paper, we demonstrate that a focused hot electron beam is produced at the cone tip, provided that electron currents flowing along the surfaces of the cone sidewalls are efficiently generated. The influence of various interaction parameters over the formation of these wall currents is investigated. It is found that the strength of the electron flows is enhanced for high laser intensities, low density targets, and steep density gradients inside the cone. The hot electron energy distribution obeys a power law for energies of up to a few MeV, with the addition of a high-energy Maxwellian tail.

Maternal situations: Sectarianism and civility in a divided city

This paper explores the tensions between civility and sectarianism in contemporary Belfast. Drawing on interviews with mothers engaged in raising young children in the largely working class and divided inner city, the paper offers a pragmatic account of the dynamics of social reproduction and change. This is pursued through an analysis of the interplay between expectations of civility and sectarianism in four specific situations: walking, shopping, playing and schooling. The tensions and dilemmas of maternal action as the divided inner city is navigated indicate the constitutive role situations play in shaping maternal action. The situation of motherhood itself, both at the centre of ethno-national reproduction and at the interface of public and private life, is not insignificant in routinely drawing mothers into the everyday dynamics of post-conflict continuity and change.
