Ten Questions Shaping 21st-century Earth Science Identified

ScienceDaily (Mar. 15, 2008) — Ten questions driving the geological and planetary sciences were have been identified in a new report by the National Research Council. Aimed at reflecting the major scientific issues facing earth science at the start of the 21st century, the questions represent where the field stands, how it arrived at this point, and where it may be headed.

* How did earth and other planets form?

* What happened during earth's "dark age" (the first 500 million years)?

* How did life begin?

* How does earth's interior work, and how does it affect the surface?

* Why does earth have plate tectonics and continents?

* How are earth processes controlled by material properties?

* What causes climate to change -- and how much can it change?

* How has life shaped earth -- and how has earth shaped life?

* Can earthquakes, volcanic eruptions, and their consequences be predicted?

* How do fluid flow and transport affect the human environment?

* New Journals in 2008:

- The Journal of Proteomics covers all areas of applied and basic research in Proteomics using multi-disciplinary approaches to unravel biological processes. Emphasis is placed on translational research and biomarker discovery in human, animal, micro-organism and plant systems. The journal provides a forum for activities in proteomics and helps strengthen the links between research scientists all over the world. Articles in Press are available on: http://0-www.sciencedirect.com.ujlink.uj.ac.za/science/journal/18743919

- Elsevier announced today (3/01/08) that it is launching a new journal, the Journal of Natural Gas Science and Engineering. The journal will be published bimonthly, and will focus on the advances in the rapidly expanding area of natural gas science and engineering. The first issue will appear in late 2008. cover the fields of natural gas exploration, production, processing and transmission in its broadest possible sense. The objective of the Journal of Natural Gas Science and Engineering will be to bridge the gap between the engineering and the science of natural gas by publishing papers by and for scientists and engineers working in any field of natural gas science and engineering

A Student Guide to Footnoting for Informational Clarity and Scholarly Discourse

Abstract:

This short article is a guide for authors, student editors, and research assistants to the major types of footnotes and how to prepare them. First, I introduce the three basic types of text requiring footnote citations – those containing (a) references, (b) facts, and (c) ideas. Footnotes for references are designed to allow your readers to retrace your research and to decide for themselves whether your line of analysis is correct. Footnotes for facts are designed to provide your reader with additional background information about anything you have mentioned that may not be familiar to your readers, including potentially obscure people, places, objects, events. Footnotes for ideas are designed to place your arguments, ideas, and analyses in the broader intellectual context of those scholars who have already considered your subject, and often offers glimpses down the side avenues of discourse that cannot be pursued in the article itself. The article concludes with some guidelines for undertaking research in ways that make it easier to prepare scholarly footnotes efficiently and correctly.

Reliability of Journal Impact Factor Rankings

BMC Medical Research Methodology 2007, 7:48 (for provisional full-text - click on the titile)

Journal impact factors and their ranks are used widely by journals, researchers, and research assessment exercises.Decisions placed on journal impact factors are potentially misleading where the uncertainty associated with the measure is ignored. This article proposes that caution should be exercised in the interpretation of journal impact factors and their ranks, and specifically that a measure of uncertainty should be routinely presented alongside the point estimate.
