Moving workers with the work: State selection, key workers and spatial development policy in post-war Britain

Spatial and planning policies in Britain have increasingly become focused on regional inequalities and the creation of mixed, sustainable and balanced communities. Within these new policy paradigms the category of the key workers has emerged as an essential element in the socio-economic sustainability of any bounded area programmes have been introduced to support their needs. Yet, defining key workers is an inherently political process as it necessitates the selection of essential and non-essential workers. Theoretical approaches that highlight state selectivity and the ways in which key policy subjects and objects are identified and mobilised have become increasingly popular across the social sciences and key worker support programmes provide a clear example of these processes in action. This paper draws on archival research to explore the formation of the category ‘key’ worker as an object of government in spatial development policies of the post-war period. It examines how key worker programmes were established to tackle the economic problems of Development Areas. It argues that definitions of key workers were forged in and through particular social, political, and economic contexts and that their emergence as an object of government presupposed and reinforced the existence of different classes of workers and different types of citizens. The paper highlights the significance of such historical work in assessments of contemporary policy and academic debates concerning the changing character of sustainable communities and citizenship, regional development, and changing modes of state regulation.

Short note: Crustal deformation in the key stone network detected by satellite laser ranging

The paper presents the results of crustal deformation, as evidenced by changed station coordinates, in the Tokyo metropolitan area detected by the satellite laser ranging (SLR) technique. The coordinates of two Key Stone SLR stations, Tateyama and Kashima, were determined from 4 weeks of orbital arcs of the LAGEOS-1 and LAGEOS-2 satellites with respect to 16 SLR stations kept fixed in the ITRF2000 reference frame. The station coordinates were calculated using the NASA GEODYN-II orbital program. The orbital RMS-of-fit for both satellites was 16 mm. The standard deviation of the estimated positions was 3 mm. A jump of about 5 cm in the baseline length between the Kashima and Tateyama stations was detected in June–August 2000 by VLBI and GPS techniques. This work confirms this crustal deformation as determined by SLR and vice versa. Analysis of coordinates of these stations shows that this effect was caused by a 4.5-cm displacement of the Tateyama station in the north-east direction. The change in the vertical component was not significant.     

Oxygen and hydrogen isotope study of minerals from metapelitic rocks, staurolite to sillimanite zones, Mica Creek, British Columbia

Abstract Oxygen and hydrogen isotope analyses have been made of coexisting quartz, ilmenite, muscovite, and biotite from Late Precambrian metapelitic rocks, staurolite-kyanite to K-feldspar-muscovite-sillimanite zones, from Mica Creek, British Columbia. The δ¹⁸O and †D values of these minerals are generally uniform and do not decrease significantly with increasing metamorphic grade. This implies that there has not been significant infiltration of deep crustal, possibly magmatic, fluids into the metapelites that has been suggested for other high-grade metamorphic terranes. The uniformity of oxygen isotope compositions of the Mica Creek metapelite rocks may reflect isotopic uniformity in the sedimentary protolith rather than widespread exchange with an isotopically homogeneous metamorphic pore fluid.
Temperature estimates based upon ¹⁸O exchange thermometry for samples below the sillimanite zone are in reasonable agreement with the results of garnet-biotite Fe–Mg exchange thermometry. In the higher grade rocks, the oxygen isotope and garnet-biotite thermometry yield results which disagree by about 100°C. The highest temperatures recorded by oxygen isotope thermometry, 595°C, are at least 60°C below the minimum temperatures required by phase equilibria. These discrepancies appear to result from pervasive equilibrium retrograde exchange of oxygen isotopes between coexisting minerals. In addition, there are problems with calibration of garnet-biotite thermometry at higher temperatures. Retrograde oxygen isotope exchange may be a general characteristic of high-grade metamorphic rocks and oxygen isotope thermometry may not usually record peak metamorphic temperatures if they significantly exceed 600°C.     

Topography and palaeogeographic evolution of a middle Miocene foredeep basin plain (Northern Apennines, Italy)

The Marnoso–arenacea basin was a narrow, northwest–southeast trending, foredeep of Middle–Late Miocene age bounded to the southwest by the Apennine thrust front. The basin configuration and evolution were strongly controlled by tectonics.

Geometrical and sedimentological analysis of Serravallian turbidites deposited within the Marnoso–arenacea foredeep, combined with palaeocurrent data (turbidite flow provenance, reflection and deflection), identify topographic irregularities in a basin plain setting in the form of confined troughs (the more internal Mandrioli sub-basin and the external S. Sofia sub-basin) separated by an intrabasinal structural high. This basin configuration was generated by the propagation of a blind thrust striking northwest to southeast, parallel to the main trend of the Apennines thrust belt.

Ongoing thrust-induced sea bed deformation, marked by the emplacement of large submarine landslides, drove the evolution of the two sub-basins. In an early stage, the growth and lateral propagation of a fault-related anticline promoted the development of open foredeep sub-basins that were replaced progressively by wedge-top or piggy-back basins, partially or completely isolated from the main foredeep. Meanwhile, the depocenter shifted to a more external position and the sub-basins were incorporated within an accretionary thrust belt.     

Women and the access to knowledge and new technologies: The case of Pisa

Emphasis has been given to a number of aspects which characterise technological development in today's economic systems and which have an impact on the working environment and on gender differences. Technological change is leading to a strong divide between knowledge “producers” and “users”. The possibility of access to one or both knowledge systems indicates the extent of women's participation in the economic and spatial transformations brought about by the new technologies. This research aims to analyse the development of new technologies and the presence of the female workforce in the field of new knowledge generation, and also to verify gender-related conditions in learning and using new technologies. In particular, an analysis has been carried out of the empirical case study of Pisa, a point of reference for comparisons with other Italian and European cases. The research focuses on: the examination of women's capabilities in the field of new technologies through the analysis of University training courses; the analysis of women's presence and status among the university staff, especially in science and technology; a detailed survey of female employment in innovative sectors. The results of the research emphasise the gender perspectives of inclusion — as regards the application of technologies — and exclusion — as regards the generation of knowledge — of women in or from new technologies. At the same time, the research stresses the growth of women's roles in this sector during recent years and, by reconstructing life histories, underlines the conditions and difficulties that have been met by women entering these new types of employment.
