Origin of Life – RNA Self Replicators

by ogremkv in Cassandra's Tears

We have previously established that organic compounds, including nucleotides, are trivially easy to produce from inorganic sources.  We have also established at least two methods from which long chain RNA molecules could develop without organic processes… including one that requires … Continue reading →...

March Madness: Priceless For Some, Overpriced For Others.

When I was in college, I slept outside in a tent almost every night during the 2 coldest months of the year. OK, before you call me crazy, there’s more to the story. I actually did this for four years … Continue reading →... Read more »

Intensity & Training to Failure [Muscle Gain]

by Matt Perryman in

Heavy is always better, right? That's the going mantra. Lift heavy things and you'll grow and get stronger. I push this position myself, because I think it's mostly right. If you want to reap gains from a strength training workout, you focus on the basics. Anything involving a barbell, picking it up, putting it ...

Managing Strategic Partnerships

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management

Setting up the right partnerships is hard to do. There are multiple levels to the decision with which companies to setup formal relations and how deep this relationship should be? Christopher and Jüttner (2000) develop a framework for managing partnerships. The full paper can be found here.

The authors use focus group interviews and multiple case studies to gain insights into practitioners' experiences.
Several factors are affecting an increasing focus on partnership manageme........ Read more »

Art in the Eye of the Beholder: Preliminary Evidence?

by Maria P. in noustuff

Does monocular viewing affect judgement of art? According to a 2008 paper by Finney and Heilman it does. The two researchers from the University of Florida inspired by previous studies investigating the effect of monocular viewing on performance on visual-spatial and verbal memory tasks, attempted to see what the results would be in the case [...]...

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?

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

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 »
