The Chinese version of the Modified Barthel Index (MBI-C) seems to be valid and reliable for use with older people with stroke. Changes were made to the item content and the rating criteria that were specific to Chinese culture. The structural validity and the reliability of the Chinese version were shown to be robust across the original and Chinese groups.

This pilot study investigated teachers' symptoms of stress and their coping strategies. Measurements of 'stress levels' and 'coping strategies' used were acquired by constructing a questionnaire made up of four individual standardized questionnaires. The data were analysed by a series of correlational analyses that highlighted significant relationships between ways of coping and levels of distress. Differences between the stress-related areas were measured using the Friedman test and Wilcoxon signed rank test for hierarchy. The findings implied that 'escape avoidance', 'accepting responsibility' and 'uncontrolled aggression' were used as negative coping strategies and only one strategy, 'exercise', was indicated to be an effective way of coping. The teachers' strategies were examined for similarities and differences with those recommended by occupational therapists. This pilot study was limited to two schools and it is recommended that it be extended to better generalize the results. Furthermore, ways of coping, as measured by psychological measures, do not seem to reduce stress so it is possible that the activity-based Stress Management Questionnaire, as advocated by Stein et al. (2003), might be more advantageous.

Background Dinoflagellates in the family Symbiodiniaceae are important photosynthetic symbionts in cnidarians (such as corals) and other coral reef organisms. Breakdown of the coral-dinoflagellate symbiosis due to environmental stress (i.e. coral bleaching) can lead to coral death and the potential collapse of reef ecosystems. However, evolution of Symbiodiniaceae genomes, and its implications for the coral, is little understood. Genome sequences of Symbiodiniaceae remain scarce due in part to their large genome sizes (1–5 Gbp) and idiosyncratic genome features. Results Here, we present de novo genome assemblies of seven members of the genus Symbiodinium, of which two are free-living, one is an opportunistic symbiont, and the remainder are mutualistic symbionts. Integrating other available data, we compare 15 dinoflagellate genomes revealing high sequence and structural divergence. Divergence among some Symbiodinium isolates is comparable to that among distinct genera of Symbiodiniaceae. We also recovered hundreds of gene families specific to each lineage, many of which encode unknown functions. An in-depth comparison between the genomes of the symbiotic Symbiodinium tridacnidorum (isolated from a coral) and the free-living Symbiodinium natans reveals a greater prevalence of transposable elements, genetic duplication, structural rearrangements, and pseudogenisation in the symbiotic species. Conclusions Our results underscore the potential impact of lifestyle on lineage-specific gene-function innovation, genome divergence, and the diversification of Symbiodinium and Symbiodiniaceae. The divergent features we report, and their putative causes, may also apply to other microbial eukaryotes that have undergone symbiotic phases in their evolutionary history.
