Basic principles and theory

Some of the important types of coordination compounds occur in biological systems (for example, heme and chlorophyll). There are also significant applications of coordination compounds that involve their use as catalysts. The formation of coordination compounds provides the basis for several techniques in analytical chemistry. Because of the relevance of this area, an understanding of the basic theories and principles of coordination chemistry is essential for work in many related fields of chemistry. In the next few chapters, an introduction will be given to the basic principles of the chemistry of coordination compounds. 

The immediate impression is that the risk-homeostasis theory may be in conflict with the basic theories and principles of SHE information systems. We tend to evaluate SHE information systems by looking into the safety measures that have been implemented as a result. They are often of the non-motivational type that according to the risk-homeostasis theory will have marginal effect. In general, the SHE-information-system approach does not involve any particular preferences as to the selection of remedial actions. They may be motivationally oriented as well as non-motivational. 

Part II reviews some of the basic theories and principles in the design of SHE information systems. Thereafter, an accident model is introdnced that represents a synthesis of many existing models. It provides a framework for a presentation of the different types of methods and tools in Parts HI to V. Part II also introduces a number of theoretical concepts and principles including accident-barrier theory, theories on human performance and errors, and feedback mechanisms in decision-making. This part ends with a set of criteria for the evaluation of SHE information systems.
