Dynamic schema model

The model presented in Figure 12.2 integrates the dynamic schema model developed by Price (2002) with the traditional Beckian model of stress (Beck 1987 Beck et al. 1985) outlined in Chapter 1 and Young s schema-focused model (Young et al. 2003) presented earlier in this chapter. The model places particular emphasis on the re-enactment of early maladaptive schemata (EMS) and behavioural coping strategies in the context of the workplace in the causation and maintenance of occupational stress. 

Concerning the implementation aspects of FireS, we will concentrate on modeling the dynamic behavior. The graph schema shown in Fig. 5.67 defines the abstract syntax for the collaboration diagrams used in phase 4. It is an extension of the formerly introduced graph schema of Fig. 5.60, which serves as meta model for defining the static data model in phase 3.

Secondly, the model is consistent with naturahstic explanations of expertbehaviour whereby action schema are frequently activated in response to environmental stimrrh with little or no conscious processing on behalf of the operator. Indeed, the model allows for situations whereby safety breaches are contained through immediate response to the emergence of a mismatch in system state. Accordingly, error management can itself be seen as dynamic expert behavioirr rather than a serial and rational process. 

Fig. 1. Model schema of the lysosome-vacuolar apparatus in mammalian cells. The Integrated components of the membrane structured apparatus are presented as existing in dynamic equilibrium. Acid hydrolases, produced (phase 1) in the endoplasmic reticulum, are channeled and packaged in the Golgi system (phase of vesiculatlon, phase 2). The subsequent translocation of acid hydrolases or secretory product is dependent upon the metabolic state of the cell, need for segregated catabolic activity of macromolecules (phase 3), or endocytic-exocytic activity.

The determination of the inverse model encounters additional problems because the dynamic properties of the course control system are highly influenced by a steering gear. The block schema of the steering gear is shown in Figure 3...
