The paper describes exploratory research into the nature of IMP conference papers with particular focus on content. A qualitative analysis of the proceedings of the 16th annual IMP conference is presented. The results provide insights into the diversity of academic thought that fuels the development of the IMP network and allows us to begin charting the development of knowledge structures within past IMP conferences. Of particular interest are, firstly, the tentative knowledge structure that emerges, secondly, the depth of analysis that emerges from using multi dimension coding and thirdly the utility of the process of successive categorisation.

Reforms which increase the stock of education in a society have long been held by policy-makers as key to improving rates of intergenerational social mobility. Yet, despite the intuitive plausibility of this idea, the empirical evidence in support of an effect of educational expansion on social fluidity is both indirect and weak. In this paper we use the raising of the minimum school leaving age from 15 to 16 years in England and Wales in 1972 to estimate the effect of educational participation and qualification attainment on rates of intergenerational social class mobility. Because, in expectation, children born immediately before and after the policy was implemented are statistically exchangeable, the difference in the amount of education they received may be treated as exogenously determined. The exogenous nature of the additional education gain means that differences in rates of social mobility between cohorts affected by the reform can be treated as having been caused by the additional education. The data for the analysis come from the ONS Longitudinal Study, which links individual records from successive decennial censuses between 1971 and 2001. Our findings show that, although the reform resulted in an increase in educational attainment in the population as a whole and a weakening of the association between attainment and class origin, there was no reliably discernible increase in the rate of intergenerational social mobility.

This chapter analyses the successive ways in which Macmillan re-wrote his experiences of the Cuban missile crisis and in the process sought to re-configure the memory of the event in Britain.

Between 1945 and 1957, West Germany made a dizzying pivot from Nazi bastion to Britain's Cold War ally against the Soviet Union. Successive London governments, though faced with bitter public and military opposition, tasked the British Army of the Rhine (BAOR) to serve as a protecting force while strengthening West German integration into the Western defense structure. Peter Speiser charts the BAOR's fraught transformation from occupier to ally by looking at the charged nexus where British troops and their families interacted with Germany's civilian population. Examining the relationship on many levels, Speiser ranges from how British mass media representations of Germany influenced BAOR troops to initiatives taken by the Army to improve relations. He also weighs German perceptions, surveying clashes between soldiers and civilians and comparing the popularity of the British services with that of the other occupying powers. As Speiser shows, the BAOR's presence did not improve the relationship between British servicemen and the German populace, but it did prevent further deterioration during a crucial and dangerous period of the early Cold War. An incisive look at an under-researched episode, The British Army of the Rhine sheds new light on Anglo-German diplomatic, political, and social relations after 1945, and evaluates their impact on the wider context of European integration in the postwar era.

A modified tri-axial electrospinning process was developed for the generation of a new type of pH-sensitive polymer/lipid nanocomposite. The systems produced are able to promote both dissolution and permeation of a model poorly water-soluble drug. First, we show that it is possible to run a tri-axial process with only one of the three fluids being electrospinnable. Using an electrospinnable middle fluid of Eudragit S100 (ES100) with pure ethanol as the outer solvent and an unspinnable lecithin-diclofenac sodium (PL–DS) core solution, nanofibers with linear morphology and clear core/shell structures can be fabricated continuously and smoothly. X-ray diffraction proved that these nanofibers are structural nanocomposites with the drug present in an amorphous state. In vitro dissolution tests demonstrated that the formulations could preclude release in acidic conditions, and that the drug was released from the fibers in two successive steps at neutral pH. The first step is the dissolution of the shell ES100 and the conversion of the core PL–DS into sub-micron sized particles. This frees some DS into solution, and later the remaining DS is gradually released from the PL–DS particles through diffusion. Ex vivo permeation results showed that the composite nanofibers give a more than twofold uplift in the amount of DS passing through the colonic membrane as compared to pure DS; 74% of the transmitted drug was in the form of PL–DS particles. The new tri-axial electrospinning process developed in this work provides a platform to fabricate structural nanomaterials, and the core–shell polymer-PL nanocomposites we have produced have significant potential applications for oral colon-targeted drug delivery.
