The Supply Chain Uncertainty Circle

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management


How to shrink the "Uncertainty Circle" is the topic of a paper I read today. It has been written by Rachel Mason-Jones and Denis R. Towill and can be downloaded here free of charge.

This article from 1998 focusses on how to shrink the uncertainty within a supply chain and therefore improve performance, since we believe that those companies which cope best with
uncertainty, are most likely to produce internationally
competitive bottom-line performance.
This hypothesis is also backed by seve........ Read more »

Antioxidant backlash

by David Bradley in Reactive Reports Chemistry Blog

More  research is needed into antioxidants found in plants, which may actually aggravate health conditions rather than benefiting people who eat them. Specifically, quercetin and ferulic acid have been shown to aggravate kidney cancer in severely diabetic laboratory rats, according to a  study in the Journal of Agricultural and Food Chemistry. Kuan-Chou Chen, Robert Peng, and [...]... Read more »

Supply Chain Crisis Management

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management


Supply Chain Risk Management is one way to look at risks within a company (and beyond). But there are broader and more narrow disciplines as well, with Business Continuity on the one end and Supply Chain Crisis Management on the other.

I wanted to get an overview of current research on Supply Chain Crisis Management first, so today I explore "Managing supply chains in times of crisis: a review of literature and insights" by Natarajarathinam, Capar and Narayanan. The article is focussed on ........ Read more »

Friday Weird Science: SLIME MOLD TAKES TOKYO

by Scicurious in Neurotic Physiology

This week Sci continues her coverage of the IgNobel prizes, those prizes given for the greatest and WEIRDEST (but not at all useless) science on the planet. It’s an award after Sci’s own little heart. And today we get to one of my personal favorites from this year: GODZILLA SLIME MOLDS!!! Oops. This is a [...]... Read more »

Supplier Selection in a Turbulent World

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management


At the moment I am focussing more on the interviews I am conducting for my research, so I am not reading as much anymore. I therefore try to select articles which are both useful for my research and my blog.

Today I read an article with the fuzzy title "Supply chain risk in turbulent environments — A conceptual model for managing supply chain network risk" by Peter Trkman and Kevin McCormack.

The authors present a framework for the identification and prediction of supply risk.

Number Needed to Ban: a new tool for calculating the benefits of banning particular dog breeds

by The Dog Zombie in The Dog Zombie

A study published this month in the Journal of the American Veterinary Association (JAVMA) takes on the issue of whether breed-specific legislation (BSL) is effective. BSL is a tool used by some communities to attempt to reduce injuries from dog bites. The idea is that particular breeds of dogs are responsible for more than their share of injuries, so banning or otherwise controlling those breeds will result in a reduction in injuries. The group of breeds collectively known as “pit bulls” re........ Read more »

Nanodiamonds could revolutionize the current styrene synthesis industry

by Michael Berger in nanowerk

Catalytic dehydrogenation of ethylbenzene is one of the most important processes in the chemical industry world-wide. Styrene, for instance, is commonly produced using this process. The annual production of some 20 million metric tonnes of styrene is an important precursors in the plastics industry. Being able to develop a new metal-free, energy-saving, and efficient catalyst for alkane dehydrogenation would have a significant positive impact on the environment. Coke formation during the current........ Read more »

When Tyrannosauraus rex had for breakfast… another Tyrannosaurus rex

by Rogue in Into Oblivion

(This was first published at The Urban Times) In a study published in the online journal PLoS ONE yesterday, researchers show evidence for cannibalistic behaviour in Tyrannosaurus rex. Indeed, the king of the dinosaurs not only fed on other dinos, but also on fellow T. rex, say the researchers after identifying bite marks on giants’ [...]... Read more »

The ultimate cause of social disparity in preventative health behavior may be rooted in environmental harm

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

In a fascinating new article in PLOS One (open access), Daniel Nettle asks why we see social gradients in preventative health behaviors:
People of lower socioeconomic position have been found to smoke more, exercise less, have poorer diets, comply less well with therapy, use medical services less, adopt fewer safety measures, ignore health advice more, and [...]... Read more »

New analysis of population trends and their impact on global greenhouse gas emissions

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


In 40 years, there will be about 3 billion additional people living on the Earth (~9.5 billion total) compared with today.   With all of these new folks, it’s easy to think about the added demands of energy, food, and water required to sustain their lifestyles.  And in terms of climate warming, it’s hard to escape [...]...

An open or shut case for nanotechnology secrets Should nanotechnology R&D be more open to allow it to thrive in the commercial world, or should companies working in this field be more secretive?

More on genetically modified (Bt) corn: Is it an economic boon to all corn farmers?

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


There’s a new paper in this week’s issue of Science that suggests that growing a landscape mixed with genetically modified (GM) Bt corn and non-GM hybrid varieties of corn can be mutually beneficial to all corn farmers.
Why?  They argue that the populations of GM corn knock down the populations of insect herbivores enough that, on [...]... Read more »

Findings: The Causality Implicit in Language

by gameswithwords in Games with Words

Finding Causes

Consider the following:

(1) Sally hates Mary.
a. How likely is this because Sally is the kind of person who hates people?
b. How likely is this because Mary is the kind of person whom people hate?

Sally hates Mary doesn't obviously supply the relevant information, but starting with work by Roger Brown and Debora Fish in 1983, numerous studies have found that people nonetheless rate (a) as more likely than (b). In contrast, people find Sally frightens Mary more indicative of Sal........ Read more »

Are global energy supplies inadequate to slow human population growth?

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


When we think of human population change and resource use, it’s easy to assume that more people will consume more resources, such as water, energy, and food. An important corollary is that resource limitations will limit population growth.  Thomas Malthus was perhaps the most influential proponent of this idea.
However, several factors complicate this story:
(1) Affluence [...]... Read more »
