    The purpose of this review is to take stock as the historiography of rural France pauses for breath following the headlong expansion of the post-Second World War decades.It examines some of the themes that continue to exert an attraction on scholars,and also some of the most recent attempts to challenge and reformulate the research agendas inherited from the Annales historians.The works discussed below raise questions concerning growth and stagnation in the rural economy,the basic characteristics of the rural community,and the role of quantification in rural history

    Automatic assembly design project 1968/9 :|breport of economic planning committee

    Get PDF
    Investigations into automatic assembly systems have been carried out. The conclusions show the major features to be considered by a company operating the machine to assemble the contact block with regard to machine output and financial aspects. The machine system has been shown to be economically viable for use under suitable conditions, but the contact block is considered to be unsuitable for automatic assembly. Data for machine specification, reliability and maintenance has been provided

    A new proof is given of the Mattila-Melnikov-Verdera theorem on the uniform rectifiability of an Ahlfors-David regular measure whose associated Cauchy transform operator is bounded.Comment: 31 pages, 5 figure

    Not just old and sick - the 'will to health' in later life

    Get PDF
    The end of the ‘Golden Age’ of welfare capitalism in the 1970s was the prelude to a period of greater individualisation within societies and was accompanied by an increase in the importance of consumption as a way of organising social relations. During the same period there was also an expansion in the discourses aimed at enhancing the government of the autonomous self. One such discourse operates around what has been termed the ‘will to health’: it suggests that health has become a required goal for individual behaviour and has become synonymous with health itself. The generational groups whose lifecourses were most exposed to these changes are now approaching later life. We explore the extent to which social transformations related to risk, consumption and individualisation are reflected in the construction of later-life identities around health and ageing. We examine how the growth in health-related ‘technologies of the self’ have fostered a distinction between natural and normal ageing, wherein the former is associated with coming to terms with physical decline and the latter associated with maintaining norms of self-care aimed at delaying such decline. Finally, we consider anti-ageing medicine as a developing arena for the construction of later-life identities and discuss the implications of the social changes for researching later life

    The segregation of starless and protostellar clumps in the Hi-GAL l=224deg region

    Stars form in dense, dusty structures, which are embedded in larger clumps of molecular clouds often showing a clear filamentary structure on large scales (> 1pc). One of the best-studied regions in the Hi-GAL survey can be observed toward the l=224deg field. Here, a filamentary region has been studied and it has been found that protostellar clumps are mostly located along the main filament, whereas starless clumps are detected off this filament and are instead found on secondary, less prominent filaments. We want to investigate this segregation effect and how it may affect the clumps properties. We mapped the 12CO(1-0) line and its main three isotopologues toward the two most prominent filaments observed toward the l=224deg field using the Mopra radio telescope, in order to set observational constraints on the dynamics of these structures and the associated starless and protostellar clumps. Compared to the starless clumps, the protostellar clumps are more luminous, more turbulent and lie in regions where the filamentary ambient gas shows larger linewidths. We see evidence of gas flowing along the main filament, but we do not find any signs of accretion flow from the filament onto the Hi-GAL clumps. We analyze the radial column density profile of the filaments and their gravitational stability. The more massive and highly fragmented main filament appears to be thermally supercritical and gravitationally bound, assuming that all of the non-thermal motion is contributing thermal-like support, suggesting a later stage of evolution compared to the secondary filament. The status and evolutionary phase of the Hi-GAL clumps would then appear to correlate with that of the host filament.Comment: Accepted for publication on "Astronomy and Astrophysics
