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

by Matt Perryman in Myosynthesis.com

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. Independent organisations and publishers have attempted with the likes of the [...]Can we count on journal metrics? is a post from: Sciencebase Science Blog

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?

Risk, Information and Incentives in Telecom Supply Chains

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management


Supply chains risks can also be analyzed in a specific industry context and this is exactly what Agrell et al. (2004) did with telecom supply chains. They used a three tier SC (2nd tier supplier, EMS, OEM) to include the selection, coordination and motivation of independently operating suppliers in the model.

In terms of risk handling and sharing the telco industry is to some extent unique as well; there are several possible complications, like
differing business logic in the different sta........ Read more »

Ezekiel's Merkabah | Knowing, Part 3

by Michael Lombardi in a New Life in the Sea

For this last installment of our review of the film 'Knowing', we will discuss the reference to Ezekiel's Chariot, and the prophecy that it conveys.
Some background - Ezekial is the author and central protagonist of the Book of Ezekial in the Hebrew Bible which goes on to discuss his prophecies of the destruction of Jerusalem. In 592 BCE, Ezekiel describes an encounter where is is visited by God appearing in "the likeness of man" who is riding a Chariot (or Merkabah in Hebrew) accompanied ........ Read more »

Competence, Participation, Opportunity in Science Communication

by Janet Krenn in Talking Winston


“…the main concern of community activities is now increasingly about public participation, rather than public competence [of science].”


A recent study in Public Understanding of Science reveals that individuals that report “high” interest in science and technology make up a majority of the members of the general public who participate in science/policy decision making. Yet some that are very interested actually may lack a basic science competence, and what good is any discussion w........ Read more »

Codex of all Codecies | Knowing, Part 2

by Michael Lombardi in a New Life in the Sea

In continuing this review and analysis of the film 'Knowing', we must absolutely address the numeric sequence which was obsessively scribed by the character Lucinda Embry. The sheet of paper containing several hundred seemingly random digits was placed into an elementary school's 'time capsule' to be opened some 50 years later. Upon opening and rediscovery of this number sequence, we are taken on a thrilling journey to unlock the secrets embedded in this sequence of digits - which as i........ Read more »

Case Study: Stress Testing Supply Chains

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management


Stress tests are an acknowledged method to test systems under extreme conditions. The method is not only used in engineering (eg. Great picture of a Boing wing stress test (Guardian Eyewitness)), but also in business, most notably and in the banking industry. But can this method also be used to test supply chain designs?

Method / Case Study
There is limited literature on using simulation to evaluate supply chains under stress. The authors took the following approach: Determining the scope ........ Read more »
