The journey to school in Britain since the 1940s: continuity and change

The journey to school has major significance both for families and urban environments, yet little is known in detail about the ways this has changed over the twentieth century. This study uses oral history evidence to compare decisions about the journey to school in the past and the present, and to assess the impact of these changes on the mobility experience of children. The paper argues that despite obvious increases in car use, and decreases in children travelling alone, other characteristics of the journey to school in British urban areas have changed little over the past 60 years.     

The foreshore: geographical implications of the three legal systems in Great Britain

Despite the word 'foreshore' being in common usage relating to the coast, it has three distinct legal definitions in Great Britain. There are three property law regimes, English law in England and Wales, Scots law (feudal) in Scotland and Udal tenure in parts of Orkney and Shetland. These result in the boundaries between private property interests and public property interests lying in a different position on the beach area under each of these property regimes. This paper examines the physical extent of each of the foreshore definitions and highlights a number of associated issues that rely on these different boundaries fundamentally impacting upon the management of the coast.     

Remote sensing of temporal and spatial patterns of suspended particle size in the Irish Sea in relation to the Kolmogorov microscale

Suspended sediments form an integral part of shelf sea systems, determining light penetration for primary production through turbidity and dispersion of pollutants by adsorption and settling of particles. The settling speed of suspended particles depends on their size and on turbulence. Here a method of determining particle size via remote sensing measurements of ocean colour and brightness has been applied to a set of monthly satellite images of the Irish Sea covering a full year (2006). The suspended sediment concentration was calculated from the ratio between green (555 nm) and red (665 nm) wavelengths in MODIS imagery. Empirical formulae were employed to convert suspended sediment concentrations and irradiance reflectance in the red part of the spectrum into specific scattering by mineral particles and floc size. A geographical pattern was evident in all images with shallow areas with fast currents having high year-average suspended sediment concentrations (7.6 mg l⁻¹), high specific scattering (0.225 m² g⁻¹) and thus small particle sizes (143 μm). The reverse is true for deeper areas with slower currents, e.g. the Gyre southwest of the Isle of Man where turbidity levels are lower (3.3 mg l⁻¹), specific scattering is lower (0.081 m² g⁻¹) and thus particle sizes are larger (595 μm) on average over a year. Temporal signals are also seen over the year in these parameters with minimum seasonal amplitudes (a factor 3.5) in the Turbidity Maximum and maximum seasonal amplitudes twice as large (a factor 7) in the Gyre. In the Gyre heating overcomes mixing in summer and stratification occurs allowing suspended sediments to settle out and flocs to grow large. The size of aggregated flocs is theoretically proportional to the Kolmogorov scale. This scale was calculated using depth, current, and wind speed data and compared to the size of flocculated particles. The proportionality changes through the year, indicating the influence of biological processes in summer in promoting larger flocs.     

ONE NATION OR TWO? THE CHANGING GEOGRAPHY OF UNEMPLOYMENT IN GREAT BRITAIN, 1983–1988*

Unemployment affected large numbers of people in Great Britain during the 1980s. An economic upturn since the mid-1980s has resulted in declining numbers of unemployed. Disaggregated data show that the geography of unemployment decline has not led to regional convergence in numbers out of work: unemployment has fallen most in those regions which were least affected by it.

Unusual cases of mining subsidence from Great Britain, Germany and Colombia

Subsidence involves sinking of the ground surface. The movement generally is localised and may or may not involve some amount of horizontal movement. It may be rapid or take place gradually over a period of time. Subsidence may be brought about by natural causes as, for example, when the roof of a cavern in limestone is weakened to the extent that it is no longer self-supporting and so collapses. Other more exotic examples are associated with volcanism and earthquakes. Perhaps, however, subsidence is more frequently associated with movements caused by mining activities, that is, the removal of mineral deposits, be they in solid, liquid or gaseous form, from within the ground. Mining is one of the earliest activities of man and has taken place in every continent. Subsidence also can result from subsurface excavations such as tunnels, caverns, cellars and sewers. One of the added problems of some forms of subsidence is that it is impossible to predict. This, coupled with the fact that the presence of potentially collapsible voids may be unknown, unrecorded or simply forgotten about further complicates the problem. The objectives of this paper are to document and draw attention to a number of unusual examples of subsidence. These have been generated due to the mining of chalk in southern England, the collapse of slate mines and caverns in Germany, the underground extraction of evaporites in Northern Ireland, fault reactivation in Wales and northern England and the extensive extraction of pumice on the flanks of Galeras volcano in Colombia.
