The place of the inns in the commercial life of London and western England, 1660-1760

The economic history of England has long been dominated by the Industrial Revolution, examining its degree of uniqueness, and its longer-term implications for both the domestic economy and that of the nations whose advance to the modern industrial state took place rather later. In this study , scholars have tended to concentrate on the period after 1750, often dismissing the previous century rather naively in terms of 'preconditions' for industrial growth. Relatively few have looked at the later seventeenth and early eighteenth centuries in depth, except in the fields of public finance and overseas trade. For most purposes, the century before the Industrial Revolution is still, in Professor Fisher's words, a 'Dark Age'. One sector of the economy, the retail trade and retailing institutions, has been generally deprived of scholarly attention. Apart from the development of the great chain stores in the nineteenth century, the bulk of our knowledge of the sector of the economy stems from research conducted prior to 1920. While age is hardly synonymous with a lack of quality, the time had clearly come for some revision. As scholars such as Professor Eversley have come to stress the significance of changing patterns of consumption in the home market to the Industrial Revolution, this sector of the economy has increasingly demanded more research.

Heterocyclic dithiocarbazate iron chelators: Fe coordination chemistry and biological activity

The iron coordination and biological chemistry of a series of heterocyclic dithiocarbazate Schiff base ligands is reported with regard to their activity as Fe chelators for the treatment of Fe overload and also cancer. The ligands are analogous to tridentate heterocyclic hydrazone and thiosemicarbazone chelators we have studied previously which bear NNO and NNS donor sets. The dithiocarbazate Schiff base ligands in this work also are NNS chelators and form stable low spin ferric and ferrous complexes and both have been isolated. In addition an unusual hydroxylated ligand derivative has been identified via an Fe-induced oxidation reaction. X-ray crystallographic and spectroscopic characterisation of these complexes has been carried out and also the electrochemical properties have been investigated. All Fe complexes exhibit totally reversible Fe couples in mixed aqueous solvents at potentials higher than found in analogous thiosemicarbazone Fe complexes. The ability of the dithiocarbazate Schiff base ligands to mobilise Fe from cells and also to prevent Fe uptake from transferrin was examined and all ligands were effective in chelating intracellular Fe relative to known controls such as the clinically important Fe chelator desferrioxamine. The Schiff base ligands derived from 2-pyridinecarbaldehyde were non-toxic to SK-N-MC neuroepithelioma (cancer) cells but those derived from the ketones 2-acetylpyridine and di-2-pyridyl ketone exhibited significant antiproliferative activity

EDSN Development Lessons Learned

The Edison Demonstration of Smallsat Networks (EDSN) is a technology demonstration mission that provides a proof of concept for a constellation or swarm of satellites performing coordinated activities. Networked swarms of small spacecraft will open new horizons in astronomy, Earth observations and solar physics. Their range of applications include the formation of synthetic aperture radars for Earth sensing systems, large aperture observatories for next generation telescopes and the collection of spatially distributed measurements of time varying systems, probing the Earth’s magnetosphere, Earth-Sun interactions and the Earth’s geopotential. EDSN is a swarm of eight 1.5U Cubesats with crosslink, downlink and science collection capabilities developed by the NASA Ames Research Center under the Small Spacecraft Technology Program (SSTP) within the NASA Space Technology Mission Directorate (STMD). This paper describes the concept of operations of the mission and planned scientific measurements. The development of the 8 satellites for EDSN necessitated the fabrication of prototypes, Flatsats and a total of 16 satellites to support the concurrent engineering and rapid development. This paper has a specific focus on the development, integration and testing of a large number of units including the lessons learned throughout the project development

Food beyond the City – Analysing Foodsheds and Self-Sufficiency under different Food System Scenarios in European Metropolitan Regions

The debate on urban resilience and metabolism has directed increasing attention to the ecological footprint of food consumption, self-sufficiency as a means of food security, and regionalisation of food systems for shortening supply chains. Recently, metropolitan regions have proposed food policies that aim to foster local food systems connected to their cities. Our research thus focused on the relationship between urban food demand and metropolitan land use.We have developed the Metropolitan Foodshed and Self-sufficiency Scenario (MFSS) model, which combines regional food consumption and agricultural production parameters in a data-driven approach to assess the spatial extent of foodsheds as well as the theoretical self-sufficiency of the communities they serve. The model differentiates between food groups, food production systems, levels of food loss and waste as well as food origin. With regard to future urban growth, we applied the model to current and future population projections.Results show substantial variations in the spatial extent of metropolitan foodsheds and self-sufficiency levels between the case study regions London, Berlin, Milan and Rotterdam, depending on population density and distribution, geographical factors and proximity to neighbouring urban agglomerations. The application of the model as a food planning tool offers a new perspective on the potential role of metropolitan regions for strengthening urban self-sufficiency. It also enables the ex-ante assessment of spatial consequences of changes within metropolitan food systems, on both demand and supply sides. In particular, we discuss possible dietary and consumption changes, but also production and supply chain alternatives.</p
