Origins of life is a tricky business. We can’t know how it happened. We weren’t there and chemical reactions and molecules just don’t fossilize well. The point is not to show how it happened. Likewise, the point is not (necessarily) … Continue reading →... Read more »
There is a huge amount of linguistic diversity in the world. Isolation and drift due to cultural evolution can explain much of this, but there are many cases where linguistic diversity emerges and persists within groups of interacting individuals. Previous research has identified the use of linguistic cues of identity as an important factor in the . . . → Read More: Emergence of linguistic diversity in the lab... Read more »

Obstacles to Information Sharing
There are many obstacles to information sharing in a supply chain. Confidentiality is probably one of the biggest issues, but there are others not so obvious like antitrust regulations, the timeliness and accuracy of the provided information, differing technologies between the supply chain partners or a mismatch in the alignment of incentives. Therefore trust and cooperation become critical ingredients in a supply chain partnership.

This is an interesting bit of research, adding to the growing body of data trying to understand the positive or negative impacts of P2P downloading of films and the like.

Years ago in one of my criminology classes, the professor introduced us to various theories on social deviance. Criminologists want to know what makes people act up and steal, or rob you in the street for crack, or stab their neighbors in the face. That's social deviance. Lots of theories have come and gone ...

Continuing with on with articles on general Systems Design and foundational articles, today I would like to talk about Conway's seminal paper on "How Do Committees Invent" from 1968. If you want to read the paper completely, you can do so on Conway's web page.
In his article Conway describes system design at its most generic level. Be it a system to prevent natural disasters or a new product of a company.

A recent CNN news piece reported on baby dolphin deaths in the Gulf of Mexico. The report went on to discuss that these deaths were not the norm in considering the shear numbers, and the time of year - that is very early in the birthing season, indicating that some births may be premature. The report went on to imply that this may be a consequence of the BP oil disaster. Makes sense.

In several articles I talked about competing objectives to the classical cost reduction goals (eg. with responsiveness or with reducing uncertainty).
Shen and Daskin (2005) explore the "Trade-offs Between Customer Service and Cost in Integrated Supply Chain Design". The goal is to find ways to simultaneously improve customer service and reduce operating cost.
The authors model a three tier supply chain, with a supplier, distribution center, and retailer.

The buzz words for today's benthic marine scientists are undoubtedly 'mesophotic coral ecosystems', or MCEs. The term mesophotic, or middle/medium light, refers to the region of the ocean below the photic zone where light is the major driver for photosynthesis by corals and algae, but above the aphotic zone where in the dark organisms rely on other means for productivity. These transitional depths, say from 200 to 500 feet (60 to 150 meters) in depth encompass a significant area of our ocea........ Read more »

Uncertainty can be categorized in continuous risk, more slowly changing patterns, and disruptions, which describe abrupt changes in a system.
Tomlin (2006) investigates the question which supply chain strategies perform best when dealing with the later.
Mitigation vs. Contingency Planning

Yet another case study. This time on strategic network design. Why? A major problem for businesses is to find the right strategy for a given situation. And "right" here means optimal (for a given KPI).
