网格技术:改进数据访问的性能

<正>谈起网格,肯定要涉及数据、信息以及如何在分布式的基础设施上对二者进行智能化处理。而这个时候似乎更让大家着迷的是网格的计算能力,而数据在以计算为重点的网格中仅能占据次席。这是为什么呢?通常,我们从媒体对网格计算方面的报道就可以看出。例     

Open publishing

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.     

Neurocognitive predictors of reading outcomes for children with reading disabilities

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.     

Economic returns to education: What We Know, What We Don’t Know, and Where We Are Going—Some brief pointers

The estimation of the economic return to education has perhaps been one of the predominant areas of analysis in applied economics for over 50 years. In this short note we consider some of the recent directions taken by the literature, and also some of the blockages faced by both science and policymakers in pushing forward some key issues. This serves by way of introduction to a set of papers for a special issue of the Economics of Education Review.     

Developing teaching self-efficacy in research institutions: A study of award-winning professors

The purpose of this study was to assess the sources of award-wining research professors’ (six women; six men) teaching self-efficacy through the framework of Bandura’s (1986) social cognitive theory. Semi-structured interviews revealed that mastery experiences and social persuasions were particularly influential sources of self-efficacy and that these sources tended to be closely related. Professors reported that their self-efficacy had generally stabilized within their first few years of assuming a tenure-track position. Participants framed negative events in adaptive ways that had little cost to their teaching self-efficacy.     

‘The constant rejections hurt’: Skills and personal attributes needed to successfully complete a thesis by publication

The thesis by publication (TBP) is an increasingly popular approach to doctoral education that sees candidates publishing their research during their candidature, and including these outputs in their final thesis submission. Responsive to the realities of modern academia, a TBP provides doctoral candidates with opportunities to engage in the scholarly publication process, and to build their research portfolio. As the TBP gains further traction in many fields and countries, there is a need to better understand the skills and attributes needed to complete a TBP successfully. This paper draws on the views of 246 recent doctoral graduates of Australian universities to identify the skills and attributes they felt supported their success. Their responses have implications for the development and refinement of institutional policies and programs that are sensitive to the needs and experiences of doctoral candidates seeking to publish during candidature and create a TBP. As editors, peer‐reviewers, and publishers see a growing influx of papers sole‐ or co‐authored by doctoral candidates in response to the trend toward TBP, they may find themselves involved in supporting students to develop the skills and attributes needed to successfully publish during candidature.     

The European university landscape: A micro characterization based on evidence from the Aquameth project

This paper provides a new and systematic characterization of 488 universities, from 11 European countries: Finland, France, Germany, Hungary, Italy, Netherlands, Norway, Portugal, Spain, Switzerland and UK. Using micro indicators built on the integrated Aquameth database, we characterize the European university landscape according to the following dimensions: history/foundation of university, dynamics of growth, specialization pattern, subject mix, funding composition, offer profile and productivity.
