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.

Climate Change Irreversible? United Nations Chief Urges Breakthrough After Dire IPCC Report Released

ScienceDaily (Nov. 18, 2007) — Secretary-General Ban Ki-moon has challenged the world's policymakers to start devising a comprehensive deal for tackling climate change at next month's summit in Bali, Indonesia, after a United Nations report released Nov. 17 found that global warming is unequivocal and could cause irreversible damage to the planet.

Oceans Could Slurp Up Carbon Dioxide To Fight Global Warming

ScienceDaily (Nov. 20, 2007) — Researchers in Massachusetts and Pennsylvania are proposing a new method for reducing global warming that involves building a series of water treatment plants that enhance the ability of the ocean to absorb carbon dioxide from the atmosphere. About 100 such plants -- which essentially use the ocean as "a giant carbon dioxide collector" -- could cause a 15 percent reduction in emissions over many years, they say. About 700 plants could offset all CO2 emissions.

New European Loess Map

Leipzig. A new map showing the distribution of loess sediments in Europe has been published for the first time in 75 years, in digital format. With this map, Dagmar Haase, a geographer at the Helmholtz Centre for Environmental Research (UFZ), has completed the work of various researchers who had begun as far back as the 1970s and 80s to revise the last comprehensive inventory produced by Rudolf Grahmann, which appeared in Mitteilungen der Gesellschaft für Erdkunde in Leipzig in 1932. Haase and her colleagues have produced the new map with a scale of 1:2,500,000 with the help of modern digital information systems.
In total, loess soils cover around one fifth of Europe: especially in the Eastern European lowlands, in a belt north of the low mountain range, in the foothills of the Alps and the Danube basin and in various other river basins. The publication of the map in Quaternary Science Reviews marks the completion of a project on which geographers and soil scientists have been working for decades.

Climate scepticism: The top 10

What are some of the reasons why "climate sceptics" dispute the evidence that human activities such as industrial emissions of greenhouse gases and deforestation are bringing potentially dangerous changes to the Earth's climate? As the Intergovernmental Panel on Climate Change (IPCC) finalises its landmark report for 2007, we look at 10 of the arguments most often made against the IPCC consensus, and some of the counter-arguments made by scientists who agree with the IPCC.

The World University Rankings 2007

Martin Ince reveals the winners and losers in The Times Higher-QS World University Rankings 2007. The world's top ten universities are in the UK or the US, according to the annual Times Higher-QS World University Rankings published with this issue.
Harvard has emerged as the world's top university for the fourth time in succession, with Cambridge, Oxford and Yale universities all tied for second place. The UK has four institutions in the top ten this year, compared with three last year. Imperial College London makes fifth place, up from ninth last year. University College London rose 16 places, making it to ninth place. Princeton, California Institute of Technology, Chicago and Massachusetts Institute of Technology make up the rest of the top ten....
The rankings confirm the modest world status of universities in continental Europe, with the top university being France's Ecole Normale Superieure in 26th place. This places continental Europe behind institutions in Canada, Australia, Japan and Hong Kong, the US and UK.
The top 200 includes four from the developing world: two in Brazil, one from Mexico and, for the first time, an African university, Cape Town, in 200th place.
A total of 28 nations have at least one institution in the 200. Virtually every university in Australia is in the rankings, with 12 representatives, while the Netherlands, with 11, emerges as continental Europe's principal power in higher education.

First-ever 'State Of The Carbon Cycle Report' Finds Troubling Imbalance

ScienceDaily (Nov. 14, 2007) — The first "State of the Carbon Cycle Report" for North America, released online this week by the U.S. Climate Change Science Program, finds the continent's carbon budget increasingly overwhelmed by human-caused emissions. North American sources release nearly 2 billion tons of carbon into the atmosphere each year, mostly as carbon dioxide. Carbon "sinks" such as growing forests may remove up to half this amount, but these current sinks may turn into new sources as climate changes.Click on the TITLE to view the full article.

Show Your Librarian Some Love

Show Your Librarian Some Love / by Todd Gilman
Many academic librarians feel unloved and underappreciated on their campuses, and the main reason is that they sense they are viewed as second-class citizens by members of the teaching faculty.Certainly that sentiment will not come as news to librarians. I wonder, though, to what extent teaching faculty members know how their library colleagues feel.....
.....Many professors summarily dismiss librarians' earnest and repeated offers of research instruction or, at the very least, don't take full advantage of those offers. When prodded they may claim they have "too much to cover" in their courses to make time for a library visit.....
.....Your students need the library and the librarians in it. If your students didn't get enough exposure to research education before your course (and trust me, they didn't) you owe it to them to bring them in. Most undergraduates come to college having mastered only the most basic tools for research. They can use a dictionary. They can conduct a search in Google that yields results (5 million, in fact!). They may even be able to run an online search by author or title and then find the book on the shelf.....
....Better yet, why not work with that librarian to develop one or more assignments for a grade that will enable your students to apply what they have learned while the library is still fresh in their minds? That way they are sure to take the library seriously, reap the maximum benefit from their interaction with the librarian, and get practice using the library for something more than study space...

Climate: SA 'not bothered'

Some of the research findings on how South Africans feel about the Climate Change & Global Warming were published in News24 on 9/11/07.
Cape Town - Only a third of adults living in South Africa's metro areas feel that climate change or global warming will affect them. This is one of the findings of a study conducted in September by South Africa's leading marketing and social insights company, TNS Research Surveys. The company interviewed 2 000 adults in all seven of South Africa's major metropolitan areas in a study that looked at how people feel about climate change, their use of key resources and what their carbon footprint is.
Most people put issues such as crime, HIV/Aids, corruption, poverty and unemployment, and poor service and housing delivery higher in importance than climate change.
