But I thought the publishers name sounded familiar and went googling and found http://www.the-scientist.com/?articles.view/articleNo/32426/...

Which contains this gem:

"""Bolstering this trend is the so-called “gold open-access” model, in which publishing is supported not by subscription fees but by author fees. An example of a gold open-access journal is The Scientific World Journal, currently published by Cairo-based Hindawi Publishing Corporation. This megajournal covers virtually all scientific fields and imposes an article processing charge of $1,000 for each accepted article. Similarly, the better-known Public Library of Science (PLoS) journals charge authors anywhere from $1,350 to $2,900 to publish, with a discount if the researcher is affiliated with a university that is an institutional member."""

So effectively, if you are giving this article your attention, you are supporting a sketchy vanity press that does not appear to engage in the same level of peer review as more traditional journals, open-access or not.
