Preface paper to the Semi-Arid Land-Surface-Atmosphere (SALSA) Program special issue
The Semi-Arid Land-Surface-Atmosphere Program (SALSA) is a multi-agency, multi-national research effort that seeks to evaluate the consequences of natural and human-induced environmental change in semi-arid regions. The ultimate goal of SALSA is to advance scientific understanding of the semi-arid portion of the hydrosphere–biosphere interface in order to provide reliable information for environmental decision making. SALSA approaches this goal through a program of long-term, integrated observations, process research, modeling, assessment, and information management that is sustained by cooperation among scientists and information users. In this preface to the SALSA special issue, general program background information and the critical nature of semi-arid regions is presented. A brief description of the Upper San Pedro River Basin, the initial location for focused SALSA research follows. Several overarching research objectives under which much of the interdisciplinary research contained in the special issue was undertaken are discussed. Principal methods, primary research sites and data collection used by numerous investigators during 1997–1999 are then presented. Scientists from about 20 US, five European (four French and one Dutch), and three Mexican agencies and institutions have collaborated closely to make the research leading to this special issue a reality. The SALSA Program has served as a model of interagency cooperation by breaking new ground in the approach to large scale interdisciplinary science with relatively limited resources

Improved student learning in ophthalmology with computer-aided instruction
© Royal College of OphthalmologistsPURPOSE: Recent changes in the medical school curriculum and in teaching styles have stimulated the development of novel learning resources. We investigated the impact of computer-aided learning in the field of ophthalmology at a large Australian undergraduate medical school. METHODS: Clinical case studies describing common ophthalmic conditions were incorporated into a computing program which uses a problem-solving format. The program was made available to 85 medical students for a 2 week period. A control group of 20 medical students did not have access to this material. Acquisition of new knowledge was assessed as the improvement in score on a knowledge-based multiple-choice examination which students took both before and following the learning interval. RESULTS: Students in the control group showed no improvement over the test period, whilst the students who had access to the computer significantly increased their knowledge base, both for material provided on the program (p = 0.0001) and in related areas (p = 0.0015). CONCLUSIONS: Suitably constructed material on the computer is a useful aid in teaching ophthalmology to medical undergraduates. The material and the medium may also act as a stimulus for further learning.P. Devitt, J.R. Smith and E. Palmerhttp://www.ncbi.nlm.nih.gov/pubmed/1170297
