growth in web technologies and increased transparency in the literature - and data - may be contributing to a shift in our perceptions of what constitutes a prior publication. Innovative online journals with virtually unlimited space provide researchers with opportunities to produce novel (original) contributions to the literature that are clearly and transparently linked to previously published articles. These include significantly extended/re-analysed reports of previously published summary findings in journals such as Trials and legitimate or incremental updates to previous studies in BMC Research Notes.

SL is a Linux release put together by Fermilab, CERN, and various other labs and universities around the world. Its primary purpose is to reduce duplicated effort of the labs, and to have a common install base for the various experimenters. The base SL distribution is basically Enterprise Linux, recompiled from source. Our main goal for the base distribution is to have everything compatible with Enterprise, with only a few minor additions or changes. An example of of items that were added are Pine, and OpenAFS. Our secondary goal is to allow easy customization for a site, without disturbing the Scientific Linux base. The various labs are able to add their own modifications to their own site areas. By the magic of scripts, and the anaconda installer, each site is to be able to create their own distributions with minimal effort. Or, if a users wishes, they can simply install the base SL release.

THIS is the kind of thinking I needed a LOT more of when I was in (and pre-) grad school -- and for that matter, throughout my career.

In the Laysan albatross, for example, previous research has shown that a third of all bonded pairs in a Hawaii colony are two females. This behavior helps the birds, whose colony has far more females than males, by allowing them to share parenting responsibilities. It also gives more stability to the offspring of males, already bonded to a female, who mate opportunistically with females in a same-sex couple. Such a dynamic, then may force gradual changes in behavior and even physical appearance of the birds, the authors note.
