Behaviour modification process

This chapter considers how behaviour modification processes can assist to control risks and reduce injury. 

Employee behaviour modification processes, as with all other human processes, can become stale and ineffective. A significant proportion of the safety improvement comes from the early interaction between the observer and the observed. If this process becomes superficial then few improvements in safety performance can be expected. Refreshing the whole intervention process periodically is essential and can be achieved by ... 

Figure 2.8.9 provides an illustrative example that demonstrates how several levels and fxmctions of management as well as front line employees can contribute to the occurrence of an imsafe situation, ft is therefore important that behaviour modification processes are applied to people in management and supervisory roles. 

Behaviour modification processes can fail to have the aimed-for impact... 

The behaviour modification process designed does not include managers or supervisors, only front-line operators. 

There is a lack of willingness to make a sustained commitment over several years. Behaviour modification processes are seen as a quick fix to boost safety performance. 

For success, the organisation must be ready to adopt a behaviour modification process and the factors which indicate this is so include ... 

It must be understood that behaviour modification processes are inappropriate where failure will result in a serious or fatal injury. Human beings by their very nature are not perfect - they fail. If the consequence of a single failure is so serious, the risk must be controlled by other means. 

The model thus shows how thresholds in the phosphorylation-dephosphorylation cascade controlling cdc2 kinase play a primary role in the mechanism of mitotic oscillations. The model further shows how these thresholds are necessarily associated with time delays whose role in the onset of periodic behaviour is no less important. The first delay indeed originates from the slow accumulation of cyclin up to the threshold value C beyond which the fraction of active cdc2 kinase abruptly increases up to a value close to unity. The second delay comes from the time required for M to reach the threshold M beyond which the cyclin protease is switched on. Moreover, the transitions in M and X do not occur instantaneously once C and M reach the threshold values predicted by the steady-state curves the time lag in each of the two modification processes contributes to the delay that separates the rise in C from the increase in Af, and the latter increase from the rise in X. The fact that the cyclin protease is not directly inactivated when the level of cyclin drops below C prolongs the phase of cyclin degradation, with the consequence that M and X will both become inactivated to a further degree as C drops well below C. ... 

The possible roles of 5-HT4-RS in emotional and rewarding processes are only suggested by their presence in limbic structures such as septum, nucleus accumbens, ventral pallidum, and frontal cortex in human (Table 4, Figure 5) [55, 56]. One has to take in account that steroid release elevates mood and consequently putative behavioural modifications induced by 5-HT4-R agonists could be complicated by these effects [98, 99, 137].

Early laboratory and field study work carried out by Adam and Scott (1971), Adam (1975), McCarthy (1978) and Kim and Hammer (1976) had already demonstrated the potential of behaviour modification techniques in a quality improvement process. These studies, however, tended to focus on specific, time-bound experiments within a particular setting or occupation. We were much more interested in applying a behaviour-based approach within a plant operating a continuous production process, involving several departments, and consisting of multiple skills and skill levels. So, it seemed to us that quality behaviour, unlike safety behaviour, would be contingent on interactions with other people and we would need to optimize... 

The application of load in materials produces internal modifications such as crack growth, local plastic deformation, corrosion and phase changes, which are accompanied by the emission of acoustic waves in materials. These waves therefore contain information on the internal behaviour of the material and can be analysed to obtain this information. The waves are detected by the use of suitable sensors, that converts the surface movements of the material into electric signal. These signals are processed, analysed and recorded by an appropriate instrumentation. 

Characterization of zeolites is primarily carried out to assess tire quality of materials obtained from syntliesis and postsyntlietic modifications. Secondly, it facilitates tire understanding of tire relation between physical and chemical properties of zeolites and tlieir behaviour in certain applications. For tliis task, especially, in situ characterization metliods have become increasingly more important, tliat is, techniques which probe tire zeolite under actual process conditions. 

Although specific calculations for i and g are not made until Sect. 3.5 onwards, the mere postulate of nucleation controlled growth predicts certain qualitative features of behaviour, which we now investigate further. First the effect of the concentration of the polymer in solution is addressed - apparently the theory above fails to predict the observed concentration dependence. Several modifications of the model allow agreement to be reached. There should also be some effect of the crystal size on the observed growth rates because of the factor L in Eq. (3.17). This size dependence is not seen and we discuss the validity of the explanations to account for this defect. Next we look at twin crystals and any implications that their behaviour contain for the applicability of nucleation theories. Finally we briefly discuss the role of fluctuations in the spreading process which, as mentioned above, are neglected by the present treatment. 

Efforts at synthesis and studies of temperature-dependent solution behaviour of these chemically hydrophobized polyacrylamides are now in progress. However, it is reasonable to point out that in this case, contrary to the hydrophilization of the hydrophobic precursor, the problems associated with additional swelling of the globular core (as the modification proceeds) are absent however, the problem of the choice of working concentration for the precursor is still present since above the coil overlapping concentration the intermolecular aggregation processes at elevated temperatures can compete with the intramolecular formation of core-shell structures. 

Hammond behaviour may be observed if the intersecting parabolae are of different curvature. The physical interpretation of this difference in curvature is that bond-making and bond-breaking processes are not necessarily synchronous as is assumed in conventional Marcus theory. While such a modification in the theory may overcome the inherent problem of treating anti-Hammond effects it does make application of the Marcus theory more difficult by the introduction of additional unknowns into the free energy relationship of (112).
