Infancy is a critical developmental period involving establishment of the neurological underpinnings of psychological, affective and relational functioning. The integration of findings from developmental and attachment theories and neurodevelopment has contributed to greater understanding of the significance of early relationships and the developmental impact of interactional disturbance. This ...

It is widely agreed that overtraining should be employed in order to achieve peak performance but it is also recognised that overtraining can actually produce decrements in performance. The challenge appears to be one of monitoring stress indicators in the athlete in order to titrate the training stimulus and prevent the onset of staleness. The present paper summarises a ten-year research effor...

Epidemic transmission is one of the critical density-dependent mechanisms that affect species viability and dynamics. In a predator-prey system, epidemic transmission can strongly affect the success probability of hunting, especially for social animals. Predators, therefore, will suffer from the positive density-dependence, i.e., Allee effect, due to epidemic transmission in the population. The...

This study compares the rate and perceptions of interruptions experienced by practice nurses and GPs. During two recording periods, nurses noted the number of interruptions they experienced before and during their consultations (Paxton et al 1996). The nurses reported 48.5 interruptions per 100 consultations in the first period and 30.2 in the second. Fifty per cent of nurses in the first perio...

A description is given of a practical clinical test of contrast sensitivity and of the results obtained on a normal population. An account is given of recent physiological work which illustrates the potential usefulness of the method in ophthalmology, and the clinical results obtained by the author and others are summarised.

A primary impediment to understanding how species diversity and anthropogenic disturbance are related is that both diversity and disturbance can depend on the scales at which they are sampled. While the scale dependence of diversity estimation has received substantial attention, the scale dependence of disturbance estimation has been essentially overlooked. Here, we break from conventional exam...
