  • The paper reports calculations about reasons for the exceptional growth of Japan and for the slowdown in growth in the OECD since the early 1970s. The calculations are based on a multi-region off-equilibrium dynamic model of two regions. The Japan
  • -Rest of the OECD system was on a trajectory far above dynamic equilibrium levels of profit, accumulation, and growth in 1960. The post-1973 slowdown is simply the effect of the system returning to a trajectory that is nearer dynamic equilibrium.

  • The European Soil Erosion Model (EUROSEM) : a dynamic approach for predicting sediment transport from fields and small catchments
  • The European Soil Erosion Model (EUROSEM) is a dynamic distributed model, able to simulate sediment transport, erosion and deposition over the land surface by rill and interill processes in single storms for both individual fields and small

  • Concept ; Geochemistry ; Glacial features ; Glacier dynamics ; Glacier mass balance ; Periglacial features ; Permafrost ; Rock glacier ; Spatial variation
  • This paper focuses on a long-standing debate in rock glacier literature : whether rock glaciers develop mainly from glacial or periglacial processes. It indicates that several previously held concepts of rock glacier dynamics and development should
  • be re-evaluated. In addition, it highlights the need for researchers to move beyond taxonomic arguments, and to improve understanding of fundamental aspects of rock glaciers such as climatic sensitivity, geochemistry, hydrology, dynamics, structure, mass
