Uncertainty and Supply Chain Redesign

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management

A very interesting part of Supply Chain Risk Management deals with the impact of uncertainty on the supply chain design process. Van der Vorst and Beulens (2002) address this topic, and focus on the redesign of supply chains.

They claim that sources of uncertainty can be a key driver for chain redesign and after analyzing the literature and own research (case study) they present a tool for supply chain redesign where the sources of uncertainty support the selection of the relevant strategy.... Read more »

Influenza variations, part II

by iayork in Mystery Rays from Outer Space

About 15 minutes after I wrote my last article on influenza variation, I was reading the Journal of Virology  and ran across another paper1 on the same thing, that at least partly addresses some of the missing points in the earlier ones.
To brutally truncate my earlier comments: influenza should generate a huge number of mutants [...]... Read more »

Modeling the paths of extinction

by Razib Khan in Gene Expression

Change is quite in the air today, whether it be climate change or human induced habitat shifts. What’s a species in the wild to do? Biologists naturally worry about loss of biodiversity a great deal, and many non-biologist humans rather high up on Maslow’s hierarchy of needs also care. And yet species loss, or the [...]...

Hosting a major sporting event - economic gains are unlikely, but will it bring happiness?

by BPS Research Digest in BPS Research Digest

The football World Cup in South Africa is almost upon us and the clock is ticking down on London 2012. It's a timely moment to ask: why, when it costs a country billions of pounds to host a major international sporting event, do they bother?The usual argument is that it's all about the legacy - the lasting economic benefit. But according to two economists, Georgios Kavetsos and Stefan Szymanski, the evidence for this simply isn't there. For example, there's research showing that the economic ben........ Read more »

Medical Costs For Severe Obesity Higher in The Rich?

by Dr. Arya Sharma in Dr. Sharma's Obesity Notes

A new study by Thomas von Lengerke and colleagues from the University of Hannover, Germany, published in Psychosomatic Medicine, looks at the impact of socioeconomic status (SES) on direct medical costs for severe obesity in Germany (which has a mixed private and public insurance based health care system)....

A decision framework for using fire as a restoration tool

For the land manager, fire represents a potentially valuable tool in controlling invasive species and restoring native ecosystems. But one of the challenges of utilizing fire in restoration is predicting how plants will ultimately respond to the treatment and planning accordingly...... Read more »

Saving face: Salamanders show why it's important to know thy enemies

Researchers: Voters Prefer the Candidate They Think Is Healthiest

by David Berreby in Mind Matters

If David Cameron wants to beat Gordon Brown next month, he might want to play a lot of tennis. According to this paper, anyway, gestures and small movements are enough to give people a clear impression of a candidate's overall health—and he who seems healthiest will get their vote.

It's another blow to the notion that we know what we are doing when we vote, which has taken a pounding in recent research. In 2008, for instance, Jonah Berger and his colleagues reported that where people vo........ Read more »

Silencing human RSV infection

by geekheartsscience in geek!

A new therapy based on RNA interference (RNAi) successfully reduces respiratory syncytial virus (RSV) infection in humans. The study, published free online in PNAS, demonstrates that therapeutic RNAi-based drugs are clinically effective, and suggests that similar ‘silencing’ therapies could be useful against other respiratory pathogens. RSV is an RNA virus that infects the lungs to [...]... Read more »

Battle of the diets: Mediterranean versus DASH

by Dave in The Daily Monthly

It seems like every few months we hear about some new diet that is supposed to help us melt away the pounds and add years to our lives. But how different are these diets, really? I’ve already discussed studies suggesting that the DASH diet does indeed appear to decrease risk of heart disease and reduce [...]... Read more »

How Confusion and Doubt Drive All Behavior

by Cole Bitting in Fable

Anxiety and False Assurances First

Confusion Second

Relief Third, Hopefully

Large rocks hurtle towards our heads. What happens? We duck. The process, however, is complex.

It involves answering two questions: what is that? and how do I behave? This anthropomorphic perspective is backwards and flawed. It suggests searching (for what, that and how) and then behaving.

The whole process (what, that and how) can be instinctive, like ducking the rock: body-as-it-was, object, body-as-it-is.1 Usual........ Read more »

When Vitamin D can’t replace UVB exposure: multiple sclerosis

by Colby in nutsci.org

Vitamin D is a hot topic lately, and many observational studies have linked it positively with a reduction in various disease risks.  However, we should be careful not to tout it as a panacea without large controlled studies and a deeper understanding of how it regulates various endogenous processes.
A recent publication studying UV radiation exposure [...]... Read more »

When Cutting Calories Doesn’t Cut It

by Christie Wilcox in Nutrition Wonderland

New research out of the Oregon Health and Science University may explain the discrepancy between the theory and reality of dieting. They found that, at least in some of our closest relatives, cutting calories isn't enough to lose weight because the body compensates for the reduced intake by lowering activity levels.

Global rates of forest loss – everyone’s a bastard

by CJA Bradshaw in ConservationBytes

I’ve written rather a lot about rates of forest loss around the world, including accumulated estimates of tropical forest loss and increasing fragmentation/loss in the boreal forest (see Bradshaw et al. 2009 Front Ecol Evol & Bradshaw et al. 2009 Trends Ecol Evol). For the tropics in particular, we used the index that an area [...]... Read more »

When it comes to chemistry, surfaces are the places to be. Where two phases meet, interesting stuff is bound to happen. One of the phase interactions that received increased attention during the last few years is the peculiar meeting of a liquid and a solid. One rather interesting phenomenon encountered here is the lotus effect, [...]... Read more »

6X His Protein Pulldowns: An Alternative to GST

by gkobs in Promega Connections

Pull-down assays probe interactions between a protein of interest that is expressed as fusion protein (e.g., (e.g., bait) and the potential interacting partners (prey). In a pull-down assay one protein partner is expressed as a fusion protein (e.g., bait protein) in E. coli and then immobilized using an affinity ligand specific for the fusion tag. [...]...

Installment #2 in the mini-series on multilingual signage
Much of the signage that can be found in contemporary public spaces is commercial. It is a form of advertising, and language choice in commercial signage such as shop names is a good indicator of the values associated with a particular language. The basic idea is that the [...]... Read more »
