What the Higgs is going on? The idiot’s ludicrously simple guide to what the ‘God Particle’ is… (and in under 4 minutes)

by Stuart Farrimond in Dr Stu's Science Blog

Does science make you queasy? Thinking about physics tends to make me feel rather seasick. If you’ve ever tried to imagine how big infinity is then you’ll probably know what I mean. News agencies have been buzzing with reports that the discovery of the fabled ‘God particle’ is close at hand. But who really knows … Continue reading »... Read more »

Is Facebook a waste of time for political parties? #cdnpoli #elxn41

by Anatoliy Gruzd in Social Media Lab

One of the questions during this ‘social media’ election is, can Facebook, a social networking site that was developed as a venue for friends and family to stay in touch and strengthen personal connections, also be used as an effective platform to engage in political discussion? Most of the political parties and candidates running for [...]... Read more »

Supply Chain Simulation and the Bullwhip Effect

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management


I already reviewed some articles of Denis Towill primarily because he does some interesting research on simulation and supply chains, but also because I like his clear style in his articles.
In one of his early papers (1992) he teamed up with Naim and Wikner and described state of the art strategies to fight the bullwhip effect or as it is called in the paper by its older name: Industrial Dynamics.

Social learning

by David Bradley in Sciencetext

Social networking sites, forums, blogs and wikis are increasingly open, readily available and user friendly and as such have become platforms for human interaction that can foster and promote the development of networks and learning communities. The great potential for unplanned interaction and serendipitous discovery through such tools also seems to have a synergistic effect [...]Post from: David Bradley's Sciencetext Tech TalkSocial learning ...

In the race to spread their political messages and win over voters during this year’s election, all of the leaders and their parties are making a mad dash to see who can gain the most number of followers, “Likes”, retweets, and comments, etc. on social media.  For many in the mainstream media, these absolute numbers [...]...

Practitioner Views on Supply Chain Risk Management

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management


In 2005 Uta Jüttner was researcher at the Cranfield University, UK, especially renowned for several minds working on supply chain risk management, like Martin Christopher or Denis Towill.

Key in understanding this field of research is to make an inquiry into how supply chain risks are managed in business environments. Jüttner first laid grounds for this by some conceptual work, I introduced here a while ago

Methodology
Jüttner used an exploratory, quantitative survey. They selected 17........ Read more »

The NW of the Iberian Peninsula is a remanent of the doubly vergent Hercynian Orogen (see figure attached), formed during the Devonian-Carboniferous time by the collision of Laurussia (or Euramerica) with Gondwana, forming Pangaea.

Measuring agile Capabilities in the Supply Chain

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management


Today I introduce you to the process of measuring agility in a supply chain. Agility is a major concept in the research of the last 10 years or so. I already have written some articles on this topic:
Design of Agile Supply Chains
Distribution Centers in Agile Supply Chain Design
Agile Supply Chains
Foundation for a Responsive Supply Chain

Consequently, the goal of today's article is to expand on those and define what are the key factors of SC agility and how it could be measured.

Supply Chain Management Literature Review

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management


It's not that there are no articles on supply chain risk management anymore. But after writing on current research in the last weeks (like the one on system failure here) I have been wondering more about the foundations of supply chain management in general. So I decided to review an article today on general supply chain management research, in this case a literature review by Sachan and Datta (2005).
The complete article can be found here.

The analysis is pretty straight forward,........ Read more »

How old am I?

by Sean Roberts in A Replicated Typo 2.0


Tweet


It’s my birthday!  But how old am I?  Well, that’s not such a straightforward question.  Even a seemingly well-defined concept such as age can be affected by cultural factors
First, my age in years is a bit of an estimate of the actual amount of time I’ve been alive, due to leap-years etc.  Second, a year is . . . → Read More: How old am I?... Read more »
