There is increasing pressure from academia to make the results of publicly funded research freely available to all. Preprint archives have grown up in some disciplines, and institutional archives are now being developed. While openly accessible preprints seem to have damaged publishers less than was originally feared, the final published versions of articles – when combined with sophisticated retrieval software – may turn out to be a different matter. Publishers have already done much to make their content more accessible through bundling, consortia licensing, access for less‐developed countries, more liberal customer and author agreements, and collective licensing. Some are experimenting with open access journals, although this may not work in all disciplines. It seems clear, however, that there are elements of value in journals themselves, and in the functions performed by journal publishers, which should survive. 相似文献

This study reports on several specific neurocognitive process predictors of reading outcomes for a sample of 278 children with reading disabilities. Three categories of response (i.e., poor, average, and good) were formed via growth curve models of six reading outcomes. Two nested discriminant function analyses were conducted to evaluate the predictive capability of the following models: (a) an intervention and phonological processing model that included intervention group, phonological awareness, and rapid naming and (b) an additive cognitive neuropsychological model that included measures of memory, visual processes, and cognitive or intellectual functioning. Over and above the substantial explanatory power of the base model, the additive model improved classification of poor and good responders. Several of the cognitive and neuropsychological variables predicted degree of reading outcomes, even after controlling for type of intervention, phonological awareness, and rapid naming. 相似文献
