STS-51L Challenger Tragedy | 25 Years Today

by Michael Lombardi in a New Life in the Sea

Twenty-five years ago this very morning (at age 6) I was sitting on a tile floor in the hallway of Martin Elementary School in Seekonk, Massachusetts watching history unfold in real-time. This school assembly followed a series of classroom lessons about space - our solar system, the moon, and exploration.
As the world turns, it often takes tragedy to so well ingrain lessons to be learned, and this case was no exception. As I sat there with three classrooms worth of schoolmates, I watc........ Read more »

Severity of Supply Chain Disruptions

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management

We already know that supply chain disruptions can be quite costly, and have not only direct but also indirect effects (eg. on stock prices). So do all supply chain disruptions have the same effect on the focal company? Of course not, but what are the driving factors that influence the impact?

In their conceptual note Craighead et al. (2007) analyse the factors of the impact supply chain disruptions.

As many companies, the authors take the view that supply chain disruptions are inevitable ........ Read more »

Process oriented Approach to Supply Chain Risk Management

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management

Supply Chain Risk Management started from the need to better control the risks within Supply and Demand Networks. The processes in (Corporate) Risk Management have been developed and convene in the classic, cyclic processes:Risk IdentificationRisk AssessmentMeasures (Development and Implementation)Risk Monitoring

Hallikas et al. (2004) tried to transfer this process into the supply chain setting.Figure 1: Risk Diagramm (Hallikas et al. 2004) Continue reading "Process oriented Approach to S........ Read more »

Weekend Short Stories

by Matthew DiLeo in The Scientist Gardener

Some pretty cool links for your weekend:

Jurassic Park beer:

Fossil Fuels Brewing Co. makes beer with an Eocene-era yeast, formerly encased in a 45 million year old chunk of amber! Incredible, but apparently true. Viable Bacillus spores were discovered first in 25-40 million year old amber by Raul Cano (these spores are so tough you can't kill them with an autoclave). He then founded a startup (Ambergene) with the hopes of discovering ancient antibiotics (this was back during the natural ........ Read more »

Supply Chain Disruptions and Shareholder Wealth

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management

In last weeks article (Hendricks and Singhal, 2005) I described the effects of supply chain glitches on supply chain performance. This week should be viewed an update to that.

Already in 2003 Hendricks and Singhal showed in an article the devastating effects supply chain glitches can have on the shareholder value. Up to that time a strong correlation between excellence in supply chain management and shareholder value has always been presumed. Many have alluded to the compelling bottom-line........ Read more »

Merger Success and Supply Chain Integration

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management

What are the major obstacles to a successful merger? Today I'll have a look at the 2003 article by Langabeer and Seifert. The authors argue that supply chain integration plays a major role before, during and after the merger.

Why is the Supply Chain Key?
The authors start by making the case for the supply chain as one of the major drivers of financial performance in a company. After analyzing quantitative data from 400 mergers during a ten-year period, exploring relationships between merge........ Read more »

Third-hand tobacco smoke

by David Bradley in SciScoop Science Forum

Smokers, primarily, put their own health at risk with their habit, but their second-hand smoke puts others at risk too. New research now suggests that there are risks from so-called “thirdhand smoke”, toxic particles and aerosols released from surfaces that have previously been exposed to tobacco smoke. Now, I hate tobacco smoke as much as [...]Third-hand tobacco smoke is a post from: SciScoop Science News

Supply Chain Disruptions and Operating Performance

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management

I just realized, that up to now I have not written much about why Supply Chain Risk Management should be an important factor many more companies.

Hendricks and Singhal wanted to understand this as well and researched on what effect a missing supply chain risk management can have on a company's performance. They therefore started a research series, the first article was on the "Effect of Supply Chain Glitches on Shareholder Wealth" (mentioned here). And today I have a look at their second a........

Protein Crystallization, biologics style

by Peter Nollert in Protein Crystallization Blog

Looking beyond your typical day-to-day work and finding out what ‘the rest of the world’ is doing can be a lot of fun. This is one of the reasons I’m enjoying myself so much at the PepTalk 2011 meeting that is currently taking place in San Diego. As I’m learning about the unique challenges faced in protein drug formulations I am quite surprised at the arsenal of analytical techniques that are available to investigate the ‘health’ of a protein prep.

Managing Supply Chains with multiple Pipelines

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management

Companies offer a smaller or larger range of products serving different markets, depending on their history and primarily the respective business model.

From a supply chain management point of view this poses the question if it is ok just to use the same supply chain strategy for all those products.

Pipelines vs. Supply Chains
Aitken et al. (2005) make a convincing argument against this approach and instead suggest the "pipeline" to describe the specific operational mechanisms and procedu........ Read more »

Definition of Risk

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management

What is risk anyway?
I read this paper already some time ago. It is very important to have a clear definition of the terms used in research. But from my previous experience I know that also in business a clear understanding of the different aspects of risks is important to stay consistent.

Case Study
At a client I was involved in a company wide risk assessment. The participating middle managers were required to list and assess relevant risks using an Excel sheet. There were predefined cate........ Read more »

Invisible hairs cause baldness

by sciencebase in Sciencebase Science Blog

A topic close to my scalp: male-pattern baldness. Regular readers will be aware of my long, wavy locks from teenage years. But, as I got older, it all waved goodbye (my Dad’s joke! He’s even less than cranially hirsute too). Now, scientists in Pennsylvania reckon they have shown that faulty stem cells in the scalp [...]Invisible hairs cause baldness is a post from: Sciencebase Science Blog

Learn from Christine O'Donnell's Possible 'Witch Trial': Be Cautious in the Court of Public Opinion

by Dr. Ken Broda-Bahm in Persuasive Litigator

By: Dr. Ken Broda-Bahm - When Christine O'Donnell, the Tea Party favorite who won the Republican nomination for a Delaware Senate seat before losing in November's general election, received word of an U.S. Attorney's Office investigation and possible charges stemming from misuse of about $20,000 in campaign funds to pay her personal expenses, she immediately took to the airwaves. On a variety of network and cable news shows, she unequivocally denied the charges and went further to call the inves........ Read more »

Effective Performance Management

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management

Aviation and steering a company can be viewed as somehow alike. At least this is the starting point for the article by Srinivas (2009) reviewed today.

Aviation Analogy
But unlike companies a pilot has some advantages: a clear starting point, a given destination, he knows on which path to get there, he knows anytime if he is off course and he also knows how to get back on track.

Company as a staggering Airplane
On the other hand within a company you have a hard time defining those parame........ Read more »

So maybe reading *should* be harder

by gameswithwords in Games with Words

Some weeks back I chided Jonah Lehrer for his assertion that he'd
love [e-readers] to include a feature that allows us to undo their ease, to make the act of reading just a little bit more difficult. Perhaps we need to alter the fonts, or reduce the contrast, or invert the monochrome color scheme. Our eyes will need to struggle, and we’ll certainly read slower, but that’s the point: Only then will we process the text a little less unconsciously, with less reliance on the ventral pathway. We ........ Read more »

Burrowing Owls Embark on Cross-Continent Migration

by Scott A. in JournOwl

I’ve definitely been neglecting my journal reading over the last few months, and if I want to be honest it’s probably more like a 6 month hiatus.  As I returned from a field visit in Winters, California, I got the itch to see what’s up with the latest in raptor research.  And the little voice [...]...
