Origins of Life – Darwin’s Little Warm Pond

by ogremkv in Cassandra's Tears

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 »

Emergence of linguistic diversity in the lab

by Sean Roberts in A Replicated Typo 2.0


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...

Information Sharing in Supply Chains

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management

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.

Drivers of Information ........ Read more »

Research Suggests that File Sharing has a Positive Effect of Film Audiences

by Tomas Rawlings in A Great Becoming

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. (The US General Accounting Office did a huge survey of the reseach in 2009 and were unable to conclude a positive nor negative effect either way.) This [...]... Read more »

Origins of Life – Can RNA Spontaneously Assemble?

by ogremkv in Cassandra's Tears

We know that it is almost trivial for inorganic compounds to spontaneously react to form organic compounds.  We can see this in hundreds, if not thousands of similar experiments since Miller-Urey.  We can also observe these organic products in places … Continue reading →... Read more »

Origins of Life – What are the odds?

by ogremkv in Cassandra's Tears

I hope to make this the first in a series of posts about current (relatively) origins of life research.  The reasoning behind this is two-fold.  The first is because I’m curious and the blog provides an opportunity to share what … Continue reading →... Read more »

The Cortical Lottery: Dopamine and the Activity Set-point [Research Review]

by Matt Perryman in

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 ...

How Systems Design Themselves

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management

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.

Actors and Stages of Design
Under most circumstances the newly designed system has a........ Read more »

Effects of the Anthropocene | Indicator Species

by Michael Lombardi in a New Life in the Sea

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.

Customer Service or Cost? Optimization of the Supply Chain Design

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management

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 Effect of Pseudonymity on Blogger Credibility

by Colin Schultz in CMBR

In July, 2010, one corner of the blogosphere erupted with the seething, burning rage that online communities seem to have a unique ability to muster. The spark that lit bloggers’ fuse was a decision by SEED Media Group decision-makers to allow a team of writers from PepsiCo Inc. to operate a blog about nutrition and [...]... Read more »

Mesophotic Coral Ecosystems | the benthic buzz

by Michael Lombardi in a New Life in the Sea

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 »

Supply Chain Risk Sources, Consequences, Drivers and Mitigation

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management

I just stumbled upon one of the articles I already read about a year ago, shortly after I started my research. Beside indication of a future research agenda (see as well here), Jüttner et al. (2003) also explain some fundamental concepts of supply chain risk management.

How to get there?
Jüttner et al. decided to conduct a exploratory study with practitioner interviews and compare these results with a literature review. Four basic concepts for Supply Chain Risk Management evolved from th........ Read more »

Can we count on journal metrics?

by sciencebase in Sciencebase Science Blog

How do you rank science, how do you rate scientists, what kudos do you give their papers and what metrics do you attach to the impact of a paper? They’re questions as old as the scientific literature itself. But, no one has resolved them.

Mitigation or Contingency Strategies against Disruptions

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management

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
From case studies analyzed in literature the author first deducts disruption management strategies used in practices. The summary can be seen in figure 1.

Strategic Supply Chain Design and the Product-Relationship Matrix

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management

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).
Research question might be: Are there general categories which can be used to make different decision situations comparable? And if yes, what would optimal strategies under these circumstances be?

Seuring (2009) tries to answer the first research question using case studies. From........ Read more »
