*NATIONAL GEOGRAPHIC BEST TRAVEL BOOKS OF 2020* The curious and vanishing world of ice in Greenland, told through 24 hours in the life of a polar scientist. 'Insightful, lyrical, and personal' - Jon Gertner 'Evokes the ice sheet's magnificence and fragility' - Elizabeth Kolbert One of the least inhabited and most mysterious parts of the world, Greenland is a singular place on Earth from which to look for the future of our planet and question its history. Polar scientist Marco Tedesco, a world-leading expert on ice and on climate change, takes us along as he and his fellow researchers conduct all-important measurements to understand the dramatic changes afoot on the immense polar ice cap.

Few economic events have had a more profound or enduring impact than the German hyperinflation of 1923, still remembered popularly as a root cause of Hitler's rise to power. Yet many historians have argued that inflationary policies were, on balance, advantageous to post-1918 Germany, both boosting growth and helping to reduce reparations. The scholarly consensus is that there was no viable alternative to inflation. In Paper and Iron Niall Ferguson takes a different view. He argues that inflation was indeed an economic and political disaster, and further that there were alternative economic policies which could have stabilised the German currency in 1920. To explain why these were not adopted he points to long-term defects in the political institutions of the Reich which went back as far as the 1890s and which persisted beyond 1918. The book therefore reveals the Wilhelmine origins of Weimar's failure, as well as casting light on the origins of the Third Reich.
Shared-workspace systems with structured graphical representations allow for the free user interaction and the joint construction of problem solutions for potentially open-ended tasks. However, group modelling in shared workspaces has to take on a process-orientated perspective due to the reduced system control in shared workspaces. This text is defined as the monitoring of user actions and the abstraction and interpretation of the raw data in the context of the group interaction and the problem representation. Formally based on plan recognition and the situation calculus, an approach has been developed that incorporates an operational hierarchy for generally modelling activities. The system performs an automatic inline analysis of group interactions and the results are visualized in different forms to give feedback and stimulating self-reflection.

This Festschrift was "presented" in electronic form to Buchanan on the occasion of his eightieth birthday on October 3, 1999, after dinner in Fairfax, Virginia. As one might have expected, the response to our call for papers was vo luminous. In looking over the many contributions, we felt that a "published" Festschrift was also possible and fitting for the eightieth birthday of so prodi gious and influential a scholar as Professor Buchanan. To that end we have assembled the following volume. In selecting the papers to be included here we have basically tried to choose those papers which in some way bear on Buchanan's contributions. Perfectly good papers about issues not related to Buchanan's...
This book is the first book of its kind, focusing exclusively on the optical properties of snow. As a complex and turbid medium, snow is approached as a strongly light-scattering (in the visible spectrum) medium with large, nonspherical ice grains. The book discusses both experimental and theoretical results, as well as the remote sensing of snow using ground-based, airborne and satellite optical instrumentation. The book will be of particular importance for researchers studying snow characteristics (the size of grains, snow pollution and albedo) using various remote-sensing techniques.
Italian Economists of the 20th Century provides a unique up-to-date assessment and appreciation of the work of 12 pioneering economists. The essays - written by a group of leading international scholars - are a fitting tribute to the important contribution that Italian economists have made to 20th century economics.

Melt takes place where the surface of glaciers or ice sheets interacts with the atmosphere. While the processes governing surface melt are fairly well understood, the pathways of the meltwater, from its origin to the moment it leaves a glacier system, remain enigmatic. It is not even guaranteed that meltwater leaves a glacier or ice sheet. On Greenland, for example, only slightly more than 50% of the meltwater runs off. The remainder mostly refreezes within the so-called firn cover of the ice sheet. This eBook contains 11 studies which tackle the challenge of understanding meltwater retention in snow and firn from various angles. The studies focus both on mountain glaciers and on the Greenland ice sheet and address challenges such as measuring firn properties, quantifying their influence on meltwater retention, modelling firn processes and meltwater refreezing as well as unravelling the mechanisms within the recently discovered Greenland firn aquifers.
