Response guided strategy

Although quite a detailed picture of the compound types that are generally found in the exocrine secretions of the artiodactyls is slowly emerging, attempts to demonstrate the semiochemical activity of these compounds in field tests were not met with unqualified success, probably because it is mostly not feasible to apply the so-called response-guided strategy in work on the artiodactyls. Nevertheless, an enormous volume of chemical information has been made available to zoologists that are interested in studying these animals. 

A complementary approach to such response-guided strategies is to examine as far as possible the entire "chemical image" which one mammal presents to another, paying particular attention to those features which vary with important biological parameters, for these contain information which the species could exploit semiochemically. An emphasis on the patterns of occurrence of compounds associated with a semiochemical substrate would also accord with the view of Beauchamp et al. (1976), that mammalian chemical signals are more likely to be encoded in the patterns of occurrence of compounds rather than in individual biologically active substances. 

The responses of the beaver show that a number of components are necessary for a behavioral effect, and that the response grows more intense with increasing complexity of the chemical stimulus. Thus, what started out as an experiment using "response-guided strategy" to pin down some active components, came to demonstrate an "odor image" (Albone, 1984). 

In our present study, the bioassay response is diminshed in the course of fractionation and the "response-guided strategy" (Albone, 1984) is not appropriate. Redundant components can further complicate the bioassay, but may function biologically to ensure the effectiveness of an important scent mark. In future studies, we propose to identify and synthesize as many of the odor components as possible in order to reproduce the odor image. 

Major problems which attend the future development of the subject are associated with the need to mesh the complexities of mammalian behaviour with the complexities of chemical composition. An approach in which both response-guided and chemical image strategies are employed to unite the chemical and biological inputs seems to be the most profitable.

TDM can detect interindividual variability in pharmacokinetics that can determine clinical outcome (83, 84, 85, 86, 87, 88 and 89). It is essentially a refinement of the traditional approach of adjusting dose based on clinical response. Using this strategy, the clinician titrates the dose based on an assessment of efficacy versus the development of nuisance or toxic effects. The discussion in this chapter has enumerated those pharmacokinetic factors that may produce variable clinical outcomes in different patients taking the same medication. TDM can be used to detect those differences among patients to guide rational dose adjustment. 

As a subject matter expert on the process, the owner has the capacity to deliver results outlined in the list of owner responsibilities, mentor future process owners, assist in staff development, and accurately guide management in its strategy related to the process. The process owner s personal development of his or her process expertise is essential in delivering operational results and providing direction for future strategic changes to the process. 

Generally, an objective function is required for the adaptation strategy which guides the adaptation mechanism to produce the best settings of the controller parameters. For example, the A decay ratio specification could be employed, or the ISE criterion (Section 7.11). For instance, if the A decay ratio criterion is used, then, if any change in process parameters leads to decay ratios other than A, the adaptation mechanism adjusts the controller parameters until a A decay ratio in the controlled response is achieved once again. 

Sensitivity analysis should be an integral component of the uncertainty analysis in order to identify key sources of variability, uncertainty or both and to aid in iterative refinement of the exposure model. The results of sensitivity analysis should be used to identify key sources of uncertainty that should be the target of additional data collection or research, to identify key sources of controllable variability that can be the focus of risk management strategies and to evaluate model responses and the relative importance of various model inputs and model components to guide model development.
