Nonlinear Dynamics in Economics: A Theoretical and by Bärbel Finkenstädt PDF

1. 1 advent In economics, one frequently observes time sequence that show various styles of qualitative habit, either normal and abnormal, symmetric and uneven. There exist assorted views to provide an explanation for this sort of habit in the framework of a dynamical version. the conventional trust is that the time evolution of the sequence could be defined by way of a linear dynamic version that's exogenously disturbed by means of a stochastic technique.

Until 1,2 ka the water level rises again strongly and the Ruzizi River is reactivated (Hecky, 1978). 3 Alluvia and slope surface sediments For the interpretation of fluvial deposits on slopes and in valleys of the humid tropics under the aspects of climate and landscape change there is no universal conception existent. The alluvial deposits in the tropics are apparently more interlocked with colluvia of the interfluves and slopes than it is the case in the temperate regions. The more intensive rearrangement of coarse and fine material in the glacial periods on the slopes and in the valleys has led to a less prominent morphological development of fluvial terraces.

Considerable human impact on landscape and vegetation can be assumed as a consequence of intensified land use. Erosion processes, the replacement of forest by secondary formations, savannization and the establishment of anthropogenic plant communities are the major human induced landscape changes to be expected from at least 500 BC onwards. It is a major objective in the project’s second phase to detect and specify man-induced landscape changes in the palaeorecord. As most of the archaeological sites are located in areas where no continuous sedimentological and palynological sequences can be obtained from lake sediments, the Research Unitexploits alternative proxy-data archives and interprets them in terms of vegetation and landscape development.

Adams und H. Faure gives an overview of some of the most important geo- and bio-scientific conclusions about the development of climate and vegetation of Central Africa (and other regions) for the Quaternary. For the Central African area the following scenario resulted on the basis of the preceded proxy-data discussion: The majority of the newer geomorphologic, zoological and palaeobotanical indications underline the fact that today’s Central African rain forest spread in the Congo Basin was clearly reduced in extension during the LGM due to profound reductions in temperature and precipitation (Runge, 1992, 2001; Thomas, 1994; Kadomura, 1995, 1998).
