Open-access mega-journals
Purpose – Open-access mega-journals (OAMJs) represent an increasingly important part of the scholarly communication landscape. OAMJs, such as PLOS ONE, are large scale, broad scope journals that operate an open access business model (normally based on article-processing charges), and which employ a novel form of peer review, focussing on scientific “soundness” and eschewing judgement of novelty...
متن کاملOpen access: What price affordability?
The situation was further exacerbated by the fact that learned societies struggled to cope with the growing demand from researchers for publication outlets. Spotting a lucrative market opportunity, for-profit companies (led by Robert Maxwell’s Pergamon Press) began to launch new scholarly journals [2], and to invite learned societies to outsource their journals to them, on the promise that by d...
متن کاملOpen-Access Mega-Journals: A Bibliometric Profile
In this paper we present the first comprehensive bibliometric analysis of eleven open-access mega-journals (OAMJs). OAMJs are a relatively recent phenomenon, and have been characterised as having four key characteristics: large size; broad disciplinary scope; a Gold-OA business model; and a peer-review policy that seeks to determine only the scientific soundness of the research rather than eval...
متن کاملOptimal Design of Open Channel Sections Using PSO Algorithm
This paper applies an evolutionary algorithm, the particle swarm optimization (PSO), to design the optimum open channel section. Depth, channel side slope and bottom width are considered as the variables for rectangular, triangular and trapezoidal channels, respectively. The objective function is minimizing the construction cost of the channel section. MATLAB software is used for programming an...
متن کاملFour Steps Toward Open-Ended Evolution
In 1998, Bedau et al. de ned a set of metrics for characterizing the long-term evolutionary dynamics of a system. They argued that no known arti cial system demonstrates the unbounded evolutionary activity observed in the fossil record. In response we have developed a series of toy models that approach and eventually succeed in demonstrating unbounded evolutionary activity. The underwhelming su...
