Do women and men differ in their acceptance of climate warming?

by Phil Camill in Global Change: Intersection of Nature and Culture


In my series on why people don’t engage climate change, we saw major socioeconomic and demographic differences in how people perceive climate change.
In the current issue of Population and Environment, Aaron McCright authors an article, The effects of gender on climate change knowledge and concern in the American public, in which he examines whether women [...]... Read more »

Glucosamine chondroitin = FAIL

by David Bradley in SciScoop Science Forum

Glucosamine and chondroitin do not work in alleviating the pain of osteoarthritis (of hip or knee), other than perhaps as an expensive placebo that sufferers who do gain some relief daren’t stop paying for. A new meta analysis of 10 trials amounting to 3803 patients has been carried out. On a 10 cm visual analogue [...]... Read more »

Going green… literally

by Brian Lambson in Berkeley Science Review Blog

While impressive, the last few decades of human achievement in photovoltaics pale in comparison to nature’s equivalent technology: photosynthesis. Just look at the numbers—every year photosynthesis produces about 3,000 exajoules (EJ) of chemical energy, or 7 x 1017 kilocalories, which equates to about half the total energy stored in the world’s petroleum reserves (and approximately the average daily caloric intake of eating champ Joey Chestnut). Compare this to the 0.1 EJ of electrical en........ Read more »

Supply Chain Risk Management Dissertations (Process oriented Risk Management of Product Risks)

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management


This is the second contribution to my series on doctoral dissertations on Supply Chain Risk Management. An immense effort and dedication is spent on these works only to find the results hidden in the libraries. So the goal is raise interest in their research.

Author / Topic
This dissertation was written by Jörn Dahmen 2009 as his doctoral thesis at the RWTH, Aachen (one of the most renowned Technical Universities in Germany). It was published by Shaker, Aachen and can be ordered here from........ Read more »

Finding Truth in a Messy World

by jebyrnes in I'm a chordata, urochordata!

*-note, this was derived from a combination of emails between myself and my former phd advisor. See if you can pick out who is arguing what and where. It’s fun – well, for some of you, anyway. How do we know the world? This is a seemingly simple and vast question – one with no [...]... Read more »

Foundation for a Responsive Supply Chain

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management


In the following I summarize the major points of the article "Responsive supply chain: A competitive strategy in a networked economy" by Gunasekaran, Lai and Cheng (2008).

Responsive Supply Chain (RSC)
The authors define a RSC to contain both aspects of Agile Manufacturing and Supply Chain Management. They argue, that both complement each other in the objective to improve organizational competitiveness.

The concept of SCM, Agile manufacturing and RSC can be compared as follows:

How much would climate change if we used existing infrastructure to the end of its life?

by Phil Camill in Global Change: Intersection of Nature and Culture


Here’s an interesting thought question:  How much would global temperature warm if we used only the existing energy infrastructure (i.e., power plants, furnaces, motor vehicles) until these machines reached the end of their useful lives?  Once they died, they would be replaced by devices that did not emit CO2.
Steven Davis and colleagues addressed this question [...]... Read more »

More acupuncture quackademic medicine infiltrates PLoS ONE

by Orac in Respectful Insolence

I hate to do this to Bora again. I really do. I'm also getting tired of blogging all these crappy acupuncture studies. I really am. However, sometimes a skeptic's gotta do what a skeptic's gotta do, and this is one of those times.

As you may recall, a mere week ago I was disturbed to have discovered the publication of a truly horrifically bad acupuncture study in PLoS ONE. It had all the hallmarks of quackademic medicine: an implausible hypothesis, trying to correlate mystical concepts of merid........ Read more »

It’s A Waterbird Wasteland

by Journal Watch Online in Journal Watch Online

Maybe sewage could offer salvation. Wetlands built to filter sewage and polluted runoff have become essential habitat for some of the world’s endangered waterbirds, but pose disease risks and other problems. Now, two recent studies offer some insight into the potential conservation promise – and peril – of artificial swamps.
One of the studies, published […] Read More »... Read more »

Phantom radiation protection

by sciencebase in Sciencebase Science Blog

Ionizing radiation exists as either subatomic particles (alpha and beta particles, and neutrons) or photons (electromagnetic waves at X-ray and gamma ray wavelengths, i.e. energies of a few electron volts). The energy from such radiation can strip electrons from atoms or molecules, thus ionizing them, but it has to have an energy above a certain [...]Phantom radiation protection is a post from: Sciencebase Science Blog

For many years I was fortunate to conduct seminars for the Bureau of Research in Education (BER), an organization that provides staff development and training resources for educators in North America.  One of the principles that provided the framework for the seminars that I did, and others that the BER offers is the link between [...]

Disease detector

by David Bradley in SciScoop Science Forum

A while back my doctor did some routine tests for some vague symptoms I reported (all came back negative thankfully) and yes, I know you can get drugs to treat hypochondria. Anyway, of those tests was an ESR (erthythrocyte sedimentation rate, also known as sed rate). A test for patients with wide-ranging symptoms that may [...]... Read more »
