- This project investigated the prevalence of sensory processing problems in a clinical group and also examined the clinical effectiveness of a specialised therapeutic technique, sensory integrative therapy (SIT), in the treatment of maladaptive behaviours in two adults with learning disabilities. The Sensory Integration Inventory - Revised for Individuals with Developmental Disabilities (SII-R, Reisman and Hanschu 1992) was used to identify two clients suspected of having poor sensory processing. A single-subject experimental design (ABAB) was used to assist the objective measurement of the effects of SIT. The results suggest that the SII-R has some limitations in identifying clients who would benefit from SIT. One client (Ms D) was seen to instigate more positive interactions with her environment during and following the treatment phases; however, the overhabituated behaviours of the other client (Mr K) showed little response to SIT. These results are discussed in the form of a practitioner's update, with respect to the indicators of sensory processing dysfunction and the potential therapeutic benefits of SIT as an adjunct to therapeutic interventions for individuals with learning disabilities.

- To assess the presence or absence of lags in biotic responses to rapid climatic changes, we: (1) assume that the delta(18)O in biogenically precipitated carbonates record global or hemispheric climatic change at the beginning and at the end of the Younger Dryas without any lag at our two study sites of Gerzensee and Leysin, Switzerland; (2) derive a time scale by correlating the delta(18)O record from these two sites with the delta(18)O record of the GRIP ice core; (3) measure delta(18)O records in ostracods and molluscs to check the record in the bulk samples and to detect possible hydrological changes; (4) analyse at Gerzensee and Leysin as well as at two additional sites (that lack carbonates and hence a delta(18)O record) pollen, plant macrofossils, chironomids, beetles and other insects, and Cladocera; (5) estimate our sampling resolution using the GRIP time scale for the isotope stratigraphies and the biostratigraphies; and (6) summarise the major patterns of compositional change in the biostratigraphies by principal component analysis or correspondence analysis. We conclude that, at the major climatic shifts at the beginning and end of the Younger Dryas, hardly any biotic lags occur (within the sampling resolution of 8-30 years) and that upland vegetation responded as fast as aquatic invertebrates. We suggest that the minor climatic changes associated with the Gerzensee and Preboreal oscillations were weakly recorded in the biostratigraphies at the lowland site, but were more distinct at higher altitudes. Individualistic responses of plant and animal species to climatic change may reflect processes in individuals (e.g. productivity and phenology), in populations (e.g. population dynamics), in spatial distributions (e.g. migrations), and in ecosystems (e.g. trophic state). We suggest that biotic responses may be telescoped together into relatively short periods (50 to 150 years), perhaps disrupting functional interactions among species and thus destabilising ecosystems.
