Scientists With Data Agree…A Deepwater Oil Plume Exists in the Gulf

by Dr. M in Deep Sea News

BP want’s to deny the presence of a deepwater oil plume in the Gulf of Mexico.  The very oil plume both predicted by models published in 2003.  The very oil plume that the massive amounts of dispersant injected at depth created to prevent oil from washing ashore.  Even the government wants to deny the existence of any . . . → Read More: Scientists With Data Agree…A Deepwater Oil Plume Exists in the Gulf...

Cleaning up emissions

by sciencebase in Sciencebase Science Blog

Emissions trading is an economic workaround, a fudge if you will, to reducing one’s pollution levels by buying off the emissions credits of others who are polluting less. Emissions trading (also known as cap and trade) is a market-based approach used to control pollution by providing economic incentives for achieving reductions in the emissions of [...]Cleaning up emissions is a post from: Sciencebase Science Blog

Jumping Spiders Prefer Vegetated Corridors

by Kevin Zelnio in The Online Laboratory of Kevin Zelnio


Barriers to dispersal come in all shapes and sizes and not all are obvious. Baker conducted experiments with jumping spiders, Phidippus princeps (Salticidae) in which he manipulated corridors connecting patches of old growth fields (clover and alfalfa). Patches were either not connected (bare corridors), all connected, or partly connected by vegetated corridors (see schema [...]... Read more »

Evolution of Colour Terms: 3 Perceptual Constraints

by Sean Roberts in A Replicated Typo 2.0

Continuing my series on the Evolution of Colour terms, this post reviews evidence for perceptual constraints on colour terms. For the full dissertation and for references, go here.

The perceptual space that results from the processing of opponent colours is non-uniform (see Figure below), meaning that there are optimal ways to describe it (Jameson & D’Andrade, . . . → Read More: Evolution of Colour Terms: 3 Perceptual Constraints... Read more »

Can Energy Sector Workers Serve as Influential Public Ambassadors?

by Matthew C. Nisbet in Age of Engagement

Earlier today, in response to Sheril Kirshenbaum’s query at Discover’s Intersection blog, I spotlighted the key influence of opinion-leaders on energy related behavior.  As a follow up, let’s take a look at a new study out this month, co-authored by John Besley, an assistant professor of Communication at the University of South Carolina (and a friend of mine from our doctoral studies together at Cornell.)
In the study appearing at the International Journal of Hydrogen Ener........ Read more »

Picking Winners?

by Shaun Hendy in A Measure of Science






It seems to have become received wisdom recently that New Zealand must pick winners with its public science investment.  In this post, I argue that this is not new:  we picked our winners a long time ago, with a strong focus on agricultural and environmental sciences.  So what are the pros and cons of backing [...]...

The Evolution of Colour terms

by Sean Roberts in A Replicated Typo 2.0

In a series of posts, I’ll review the current state of the field of the Evolution of Colour Categories. It has been argued that universals in colour naming across cultures can be traced back to constraints from many domains including genetic, perceptual and environmental. I’ll review these arguments and show that if our perception is affected by our language, then many conflicts can be resolved.... Read more »

Identifying important Activities within the SCOR Process Categories

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management


The Supply Chain Operations Reference (SCOR) model has been developed by the Supply Chain Council to provide a best-practice framework for supply chain management practices and processes with the goal to increase performance.

SCOR
The SCOR model consists of five major process categories: Plan, Source, Make, Deliver and Return
Starting from that best practice processes are defined up to level three. Supply Chain Operations Reference Model (SCOR, SCC 2000)

Wolf Spider Leg Regeneration Impairs Foraging

by Kevin Zelnio in The Online Laboratory of Kevin Zelnio

Study organism, photo from Uetz Lab (click through).
Wrinn & Uetz studied how leg loss and regeneration affected the condition, growth and development time of the wolf spider, Schizocosa ocreata (Lycosidae, photo at left). Spiders may amputate their legs as a defense strategy, but it’s not clear what trade-offs exist. For instance, if a spider [...]... Read more »

Language Evolution and Language Acquisition

by Sean Roberts in A Replicated Typo 2.0

Science Bloggers: Diversifying the news

by Colin Schultz in CMBR

So you know that old, sorry debate about science journalism versus science blogging? The one where the mainstream media are the legitimate suppliers of news about the world, and bloggers are resigned to being snarky commentators? Or how about the one where blogging creates an echo chamber, where the diversity of sources withers, leaving people [...]... Read more »

Some Snails Prefer Doing It Anti-Chiral

by Kevin Zelnio in The Online Laboratory of Kevin Zelnio

Most snails walk the line and stick with doing the dirty deed missionary-style. No one even thinks about any of that kinky, low-down, unholy ways of propagating the world. But Schilthuizen and colleagues report in the Journal of Evolutionary Biology (open access!) that one disgusting species of snail actually [...]... Read more »

If you’re having a baby scan, rest assured there’s nothing to worry about here, this piece of research is about high-energy ultrasound. The difference is like comparing a research laser beam to the light from a cheap flashlight… Anyway, according to Ken Suslick, when high-intensity ultrasound passes through a liquid, the expansion wave of the [...]...

Designing the Green Supply Chain

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management


Nowadays green logistics is an often heard buzz-word, but already eleven years ago Beamon published an article about the challenges with creating Green Supply Chains.

Traditional vs. Extended Supply Chain
A traditional supply chain has been mostly a one-way street. The issues analyzed were eg. the number of echelons, buyer-supplier relationships and inventory levels.
As a basis the extended supply chain has to consider at least the recycling / re-use and remanufacturing processes to be com........ Read more »
