Sommario/riassunto |
|
Dynamic environmental processes are complex; the easiest and most effective way to understanding them lies through the disciplines of dynamic modelling and computer simulation.The prerequisite modelling fundamentals are presented in the first chapter in a manner comprehensible to students as well as to practising scientists and engineers. The second chapter describes the many environmental processes that lend themselves to modelling, for example pollution and wastewater treatment. The third part of the book provides 65 simulation examples both on the page and on an accompanying diskett |

Sommario/riassunto |
|
Lending practices of commercial banks in Afghanistan were analyzed using CAMEL ratings. Statistically significant correlations were found: Banks with worse ratings (a) had more lending to domestic clients and (b) paid less tax. There was no statistically significant relationship between profits and total assets or between lending/assets versus profit/assets. Interviews of senior management of 8 banks accounting for about 90 percent of the commercial banking system corroborated evidence that poorly rated banks lend to domestic clients, whereas highly rated banks do not lend. Banks that lend extensively domestically engage in extra-judicial, non-traditional contract enforcement. |
