Such variability probably means that social support fulfils different functions during different developmental stages or during different phases of a crisis. For example at the onset of a crisis, informational support may be more essential than tangible aid. The source of support, its density and the length of time it is operative will also be in flux. The reciprocal relationship between stress and social support must be recognized. Some stressors themselves have a direct impact on available support. Death of a spouse, for example, usually reduces the extent of the network and may have serious consequences for the survivor (Goldberg et al. 1985).

In our group of investigators at the Karolinska Institute in Stockholm, recent research has been focused on factors that promote host resistance. We have hypothesized that one such powerful factor is the health-promoting effects of well-functioning social networks and social support.

Our empirical knowledge about the accuracy of this model is still insufficient and unclear at this stage, but further insight will be gained by applying the interactive model to stress research. For example, our ability to predict disease may increase if the attempt is made to apply the model.

It is clear that there is little correlation between assessed l.Q. and what people are able to learn and do in the real world. Many cognitive researchers are proving that intelligence is, in fact, an open, dynamic system, modifiable at any age and ability level. For example, over 750 research studies based on the work of Reuven Feuerstein support his theory of Structural Cognitive Modifiability.

Smokers who express high motivation to smoke have reported, in several studies, above-average stress that they had experienced before smoking, rather than below-average stress after smoking (Parrott 1995). Consequently, stress management and anxiety reduction programmes in the workplace do have the potential of influencing motivation for smoking. However, workplace-based smoking-cessation programmes do bring to the fore the conflict between health and performance. Among aviators, as an example, smoking is a health hazard in the cockpit. However, pilots who are required to abstain from smoking during and before flights may suffer cockpit performance decrements (Sommese and Patterson 1995).

Under this hypothesis, dense hare populations decrease the quantity of suitable foods, which in turn causes a decline in the hare population.

Most importantly, there has to be demonstrable commitment to the issue of stress and mental health at work from both senior management and unions. This may require a move to more open communication and the dismantling of cultural norms within the organization which inherently promote stress among employees (e.g., cultural norms which encourage employees to work excessively long hours and feel guilty about leaving “on time”). Organizations with a supportive organizational climate will also be proactive in anticipating additional or new stressors which may be introduced as a result of proposed changes. For example, restructuring, new technology and take steps to address this, perhaps by training initiatives or greater employee involvement. Regular communication and increased employee involvement and participation play a key role in reducing stress in the context of organizational change.
