Practical considerations for working with athletes with disabilities

This paper presents general considerations for working with athletes with disabilities and the usefulness and possible modification of specific mental skills for those athletes. Common concerns for athletes with specific disabilities are discussed. Specific disabilities are considered under the headings of amputees, blind and visually impaired, cerebral palsy, deaf and hearing impaired, intellectual disabilities, and wheelchair. Arousal control, goal setting, attention/concentration, body awareness, imagery, self-confidence, and precompetition preparation are discussed in terms of disability-specific issues as well as suggestions for application.

Teaching in rural and remote schools: a literature review

In this paper. the authors examine a wide range of recent research into the preparation and support for teachers working in rural and remote schools. The paper reviews many preservice and inservice initiatives which highlight issues affecting:teaching and learning in schools outside the major metropolitan centres. The work is reviewed from an Australian perspective but evaluates research from throughout the world. The paper concludes that despite a large body of research (Gibson, 1994), that has identified the need for specialised pre-service preparation which accommodates the social and professional differences associated with work in rural and remote areas, the implementation of such programs by teacher training institutions has been sparse, lacking in cohesion and in many cases non-existent.

Climate change, coral bleaching and the future of the world's coral reefs

Sea temperatures in many tropical regions have increased by almost 1 degrees C over the past 100 years, and are currently increasing at similar to 1-2 degrees C per century. Coral bleaching occurs when the thermal tolerance of corals and their photosynthetic symbionts (zooxanthellae) is exceeded. Mass coral bleaching has occurred in association with episodes of elevated sea temperatures over the past 20 years and involves the loss of the zooxanthellae following chronic photoinhibition. Mass bleaching has resulted in significant losses of live coral in many parts of the world. This paper considers the biochemical, physiological and ecological perspectives of coral bleaching. It also uses the outputs of four runs from three models of global climate change which simulate changes in sea temperature and hence how the frequency and intensity of bleaching events will change over the next 100 years. The results suggest that the thermal tolerances of reef-building corals are likely to be exceeded every year within the next few decades. Events as severe as the 1998 event, the worst on record, are likely to become commonplace within 20 years. Most information suggests that the capacity for acclimation by corals has already been exceeded, and that adaptation will be too slow to avert a decline in the quality of the world's reefs. The rapidity of the changes that are predicted indicates a major problem for tropical marine ecosystems and suggests that unrestrained warming cannot occur without the loss and degradation of coral reefs on a global scale.
