Caging techniques for field exposures of fish to chemical contaminants
2005
The article reviews current state-of-the-art to conduct fish caging as an assessment and monitoring technique in aquatic toxicology. A multitude of scientific, practical and management factors influence and may restrict how field research is carried out. For many purposes the advantages of transplant fish caging outweigh the alternative methodologies of impact studies of xenobiotics. However, besides mortality, virtually no study has evaluated the physiological consequences of caging fish. It is not known how caging itself affects the responses of fishes to chemical pollution. The used caging densities are commonly too high. However, with the aid of variables describing physiological stress…
Calculating the regional economic impact of the olympic games
2004
This study introduces a methodological concept to combine the cost‐benefit analysis and input‐output models to create a new method to regionalize Olympic costs and benefits in order to define the economic impact at the regional level. This new form of analysis is used to calculate the regional economic impact of the Frankfurt Rhein/Main region, which bid to stage the 2012 Olympics. A generalised view of the Frankfurt case study shows patterns that are valid for all impact studies of major sport events. Finally a sensitivity analysis is used to determine critical variables.
