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

Linking Research and Practice in Science Teaching

by Jack Hassard in The Art of Teaching Science

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 »

A management strategy developed by electronics giant Motorola in the 1980s could help Coca Cola reduce the amount of water it uses to make its products, cut overall energy demands and trim its carbon footprint, according to a study published in the International Journal of Six Sigma and Competitive Advantage. Numerous companies, including Volvo, Nokia [...]... Read more »

New land for agriculture coming mainly at the expense of tropical ecosystems

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


There have traditionally been two ways to produce more food for an increasing population:  Convert native ecosystems like forests and grasslands into agricultural fields (what we call “extensification”) or make the yields on existing croplands go up, through the use of things like machinery, fertilizers, irrigation, pesticides, and GMOs (what we call “intensification”).
Historically, these processes [...]... Read more »

Segmenting Supply Chain Strategies

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management


For researchers and practitioners alike it is important to differentiate supply chain strategies.

Introduction
Not only Fisher (1997) showed, that there is no one-fits-all supply chain. But what are the criteria for should be used for supply chain segmentation?
Fisher focusses on on the product only, and he concludes, that a standard/functional product should be processed by a lean supply chain and innovative products by agile supply chains.

Genomic analysis can be powerful – in the right hands

by Rachel Bernstein in Berkeley Science Review Blog

You may have heard about the controversial genetics study connecting a set of 150 genetic markers to “exceptional longevity” (people living past 100). Everybody’s interested in living longer, so it’s not surprising that the work, published by Boston University researchers in July in the journal Science, was covered with much fanfare in many main-stream news outlets (for example, in the NY Times and Scientific American). Science even hosted a media teleconference to promote the story. Con........ Read more »

Supply Chain Risk Management Dissertations (No. 1)

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management


Today I start an irregular 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 libraries. So the goal is raise interest in their research.

Author / Topic
The first dissertation was written by Ingo Schneider in 2009 as his doctoral thesis at the Helmut Schmidt University in Hamburg, Germany. It was published by Shaker, Aachen and can be ordered here from amazon.de or your local library......... Read more »

Resolving conflicts to make finding a job easier

by David Bradley in Sciencetext

Politicians might tell you that, “the ongoing evaluation of global joblessness data can be represented by a negative slope on the current employment hysteresis”. Unemployment is on the rise, in other words. So, it’s rather timely that a powerful “meta job search” engine is being developed by Austrian and UK computer scientists.
