Family dynamics working with

This close definition of the client and service remit was true of virtually all of the practitioners interviewed. This segmentation was not an apparently intentional outcome, but a product of a prevalent model of service delivery that in being highly individualized tends to miss the influential interplay of family relationships and roles and their effect on all family members behaviours. It is just possible that a more family-centred approach that takes into account these dynamics, and works with them as they play out between family members, could achieve some alleviation of the near intolerable stresses that families seem to experience. This kind of family systems therapeutic work is not common. It is difficult, resource-intensive work and undoubtedly requires very skilful management given the emotional tenor of such intervention. As many of these practitioners described, intervention with families, even in the limited terms of enlisting help for their client, invited great caution. 

In view of this, a robust scheme based on the Hoo control theory [24] is developed in the present work. The algorithm guarantees both stability and performance for a family of perturbed plants with model uncertainties and exogenous inputs (i.e., chamber disturbances and sensor noises) over a wide range of operating conditions, an advantage especially desired for combustion dynamics problems. 

In the presence of both order-disorder and displacive, as in the KDP family, the two dynamic concepts have somehow to be merged. It could well be that the damping constant Zs becomes somewhat critical too (at least in the over-damped regime of the soft mode), because of the bihnear coupling of r/ and p. It would, however, lead too far to discuss this here in more detail. The corresponding theory of NMR spin-lattice relaxation for the phase transitions in the KDP family has been worked out by Blinc et al. [19]. Calculation of the spectral density is here based on a collective coordinate representation of the hydrogen bond fluctuations connected with a soft lattice mode. Excellent and comprehensive reviews of the theoretical concepts, as well as of the experimental verifications can be found in [20,21].
