The parameters K and n are related to the vertical and fractal dimensions of the self-affine roughness components, respectively. Surfaces roughness features with characteristic mean vertical and lateral dimensions can be described using the ABC model ... 

From the three parameters A, B and C, the rms roughness a and correlation length T can be derived. The roughness characteristics of a large variety of real surfaces can be approximated either by a single kind of PSD model or by their combinations. Typical PSD curves for the fractal and ABC model under variation of parameters are shown schematically in Fig. 5.

By varying the model parameters within reasonable limits we searched for parameter sets that met the above defined kb threshold criterion for ultra-hydrophobicity. In the case of the ABC model, parameter variation corresponds to a modification of the mean vertical and lateral dimensions of the characteristic roughness features. 

Specific results of calculated kb values for a diversity of ABC model functions are shown in Fig. 6. The model parameters A and B were varied within defined bandwidths (parameter C fixed at a value of 2.5) and translated into equivalent parameters a r and r. The mean vertical and lateral dimensions of the described roughness features are in the nanometer range. They can, however, be generally extended into the micrometer range as well, as the diagram expresses the independence of /CB on the absolute structural dimension. 

For comparison of the roughness characteristics of all mentioned nanorough optical surfaces the corresponding Master-PSD curves are shown in Fig. 19. It is obvious that the typical shape of the thin film PSDs can be well approximated by ABC model functions within the scope of the design process (Fig. 5, left).

Behavior-based safety trainers and consultants teach the ABC model (or three-term contingency) as a fi amework to understand and anatyze behavior or to develop interventions for improving behavior. As given in Principle 3, the A stands for activators or antecedent events that precede behavior B, and C refers to the consequences following behavior and produced by it. Activators direct behavior consequences motivate behavior. 

What about the intervention step This phase of DO IT involves one or more behavior-change techniques, based on the simple ABC model depicted in Figure 8.3. As I discussed in the preceding chapter, activators direct behavior and consequences motivate behavior. For example, a ringing telephone or doorbell activates the need for certain behaviors from residents, but residents answer or do not answer the telephone or door depending on current motives or expectations developed from prior experiences. The activators listed in Figure 8.3 are discussed in Chapter 10. Consequences are discussed in Chapter 11. 

Figure 8.3 The ABC model is used to develop behavior change interventions.

In Chapter 9,1 showed how the Activator-Behavior-Consequence (ABC) model can be used to diagnose the contributing factors to an incident or at-risk behavior and to decide on a plan for corrective action. With this chapter, we begin our discussion of intervention design and implementation to improve safety-related behavior. As such, the ABC model is used as introduced in Chapter 8—-as a framework for designing behavior-change interventions. 

One of the best way to describe behaviors is by using the ABC model (antecedents (activators), behaviors (at-risk events), and consequences (of exposure)). While this model has been around for many years, it is not always fully understood or used properly in assessing the workplace. 

Behaviors can be somewhat forecast by using the ABC model that stands for Antecedent, Behavior, and Consequences (what happens when the behavior occurs). An antecedent is something that comes before a behavior, and may trigger that behavior. A behavior is anything an individual does. A consequence is something that follows the behavior (ABC (Antecedent-Behavior-Consequence) Model, Fact Sheet, n.d.).
