Yes, but that’s not what I’m thinking of. Is it…getting some exercise? Yes, but that’s not what I’m thinking of. Give up? It’s….putting things away in the proper place!

Take yesterday, for example. I was peering into my nightly stack of “I’m-going-to-eventually-get-to-these-books,” when I came across the yellow covered copy of Frances Hodgson Burnett’s The Secret Garden. The only reason why I hadn’t finished yet, is that I did what I normally do when I’m infatuated with a book. I read it slowly as if each word were being analyzed with a microscope. I would ponder over an author’s choice of one word over another, for example or got lost in why a particular passage was so magical, so descriptively perfect.

Dr. Joel Schneider and I, Dr. Kevin McGrew say "no."Do psychologists who include simple pseudo-composite scores in their reports, or make interpretations and recommendations based on such scores, have a professional responsibility to alert recipients of psychological reports (e.g., lawyers, the courts, parents, special education staff, other mental health practitioners, etc.) of the potential amount of error in their statements when simple pseudo-composite scores are the foundation of some of their statements?

The results are summarized in the abstract below (click to enlarge). The WAIS-IV was found to measure the same theoretical constructs across the two countries. However, the reported difference in latent mean factor intercepts indicated that the WAIS-IV provides higher scores with Canadian subjects.

I then ran across a legal blog post where someone had investigated trends in different law terms...and I couldn't help myself but to give it a try.As described by Robert Ambrogi at the legal blog:"Using data drawn from the millions of books it has digitized covering the years 1500 to 2008, it lets you see and compare the frequency of words and phrases as they were used in books over a span of years or centuries.

When talking with others I often have trouble spitting out the exact date of publication of the various revisions of tests, as I keep track of more than just the Wechsler batteries (which are the primary IQ tests in Atkins reports). I often wonder if others question my expertise...but most don't realize that there are more IQ batteries out there than just the Wechsler adult battery....and, in particular, a large number of child normed batteries and other batteries spanning childhood and adulthood.

A team of Rice University and Lockheed Martin scientists has discovered a way to use simple silicon to radically increase the capacity of lithium-ion batteries. Sibani Lisa Biswal, an assistant professor of chemical and biomolecular engineering, revealed how she, colleague Michael Wong, a professor of chemical and biomolecular engineering and of chemistry, and Steven Sinsabaugh, a Lockheed Martin Fellow, are enhancing the inherent ability of silicon to absorb lithium ions. They believe they've figured out how to prevent silicon from cracking after a couple of cycles of absorbing and releasing lithium atoms.

Planar Energy has developed a roll-to-roll process for making larger solid lithium-ion batteries. The company, which received $4 million in funding from the Advanced Research Projects Agency Energy program this spring, says it can print solid batteries that offer three times more storage than liquid lithium-ion batteries of the same size. This boost in energy storage is possible primarily because the company's all-solid batteries don't require many of the support structures and materials that take up space in conventional batteries, making more space for energy storage.

MIT battery researcher Yang Shao-Horn thinks lithium air batteries aren't coming to market in the next 10 years. But before the technology goes commercial, researchers have to pass a gantlet of scientific challenges. A material may "breathe" oxygen into the battery excellently, but it has little commercial potential if it's platinum or gold. Lithium in the anode reacts explosively with even a little water, so it must be sheltered with a stable and, yes, cheap substance.

British company Qinetiq claims 1.6 times the energy density of existing lithium batteries at half the cost. The battery is based on lithium-ion iron-sulfide chemistry, which has a number of advantages over the chemistry of existing batteries, says Gary Mepsted, technical manager for Qinetiq's power sources group.

If this technology works out it could revolutionize the auto industry with capacity at least double current lithium batteries. A "digital quantum battery" concept proposed by a physicist at the University of Illinois at Urbana-Champaign could provide a dramatic boost in energy storage capacity--if it meets its theoretical potential once built. The concept calls for billions of nanoscale capacitors and would rely on quantum effects--the weird phenomena that occur at atomic size scales--to boost energy storage. Conventional capacitors consist of one pair of macroscale conducting plates, or electrodes, separated by an insulating material. Applying a voltage creates an electric field in the insulating material, storing energy. But all such devi...

Yesterday I discovered another reason to like electric motors: They are quieter on a river that is rich with wildlife. You end up finding more of the noisy wildlife. In my case the wildlife was on the Silver River in Florida. In particular, we were looking for the Rhesus monkeys that are descendants of monkeys that escaped (I am told) from the sets of Tarzan movies back in the 1920s. We went up the river on internal combustion engine power and didn't find the monkeys. We...

A start-up based in Menlo Park, CA, plans to sell a new type of anode for lithium-ion batteries that, the company says, will let electric vehicles travel farther and mobile devices last longer without a recharge. Amprius' lithium-ion anodes are made of silicon nanowires, which can store 10 times more charge than graphite, the material used for today's lithium-ion battery anodes. According to the company, electric vehicles that run 200 miles between charges could go 380 miles on its batteries, and laptops that have four hours of run time could last for seven hours between charges. All of the start-up activity in battery technology makes me optimistic that...

A Swiss company claims to be making strides toward a longer lasting zinc air battery. A Swiss company says it has developed rechargeable zinc-air batteries that can store three times the energy of lithium ion batteries, by volume, while costing only half as much. ReVolt, of Staefa, Switzerland, plans to sell small "button cell" batteries for hearing aids starting next year and to incorporate its technology into ever larger batteries, introducing cell-phone and electric bicycle batteries in the next few years. It is also starting to develop large-format batteries for electric vehicles. Read the full article for the details. Note that the company isn't ready to start selling tomorrow.
