OP50 Socio-Economic Inequalities in Lung Cancer Treatment
Background Socio-economic inequalities in receipt of lung cancer treatment have been demonstrated in our recently published systematic review and meta-analysis, in both universal (UHCS) and non-universal healthcare systems. These findings could not be explained by type of healthcare system or stage at diagnosis. However, not all of the included studies reported details of stage and histology, both of which influence treatment type, and very few U…
Simulated geographic variations of plant species richness, evenness and abundance using climatic constraints on plant functional diversity
Among the most pronounced large-scale geographic patterns of plant biodiversity are the increase in plant species richness towards the tropics, a more even distribution of the relative abundances of plant species in the tropics, and a nearly log-normal relative abundance distribution. Here we use an individual-based plant diversity model that relates climatic constraints to feasible plant growth strategies to show that all three basic diversity p…
East-West Orientation of Historical Empires and Modern States
Jared Diamond (1997) hypothesized that if environment is important in limiting the spread of cultures, cultural units would also tend to extend more broadly along lines of latitude than along lines of longitude. We test this hypothesis by studying the range shapes of (a) historical empires and (b) modern states. Our analysis of the 62 largest empires in history supports this conjecture: there is a statistically significant tendency to expand more…
A GIS-based Vegetation Map of the World at the Last Glacial Maximum (25,000-15,000 BP)
A preliminary, broad-scale vegetation map reconstruction for use by archaeologists and anthropologists is presented here for the world at the Last Glacial Maximum (18,000 BP, but broadly representing the interval from 25,000 to 15,000 BP). The global LGM map was produced from a range of literature and map sources, and drawn on a GIS with topographic information. Extended coastlines due to LGM sea-level drop were obtained using bathymetric informa…
Could Pre-Last Glacial Maximum Humans Have Existed in North America Undetected? An Interregional Approach to the Question
Modelling Paleoindian dispersals
It is reasonable to expect that the global dispersal of modern humans was influenced by habitat variation in space and time; but many simulation models average such variation into a single, homogeneous surface across which the dispersal process is modelled. We present a demographic simulation model in which rates of spatial range expansion can be modified by local habitat values. The broad‐scale vegetation cover of North America during the late l…
Preliminary Vegetation Maps of the World since the Last Glacial Maximum
Achieving Optimum Quality in Computer Drawing
Computer-generated line drawings are most commonly produced by pen plotters, and quality depends primarily on the equipment used. The main controlling parameters are accuracy and precision, but the plotter mechanism may impose a stepped or ragged structure on lines. Thus while they may remain within tolerance, their visual quality is affected. Pens for plotters must be chosen for reliable operation under conditions of mechanical handling, usually…
