Abuse genes

At Mind Hacks is Born to be bad?

The latest issue of Prospect magazine features a fresh in-depth analysis of whether there is such a thing as a criminal personality.

The author David Rose of the Observer notes that contemporary politicans have tended to focus on the social causes of criminality. But he points to new research showing that genetic factors are also key, in particular he highlights research by Terrie Moffitt and colleagues at the Institute of Psychiatry, including a study showing that whether childhood maltreatment leads to later increased risk of criminality depends in part on the variant of the MAOA gene that a person has. The gene codes for the enzyme monoamine oxidase A, and is involved in the regulation of neurotransmitter levels.

A person with a low activity variant of this gene who is maltreated is far more likely to develop antisocial behaviour.

MindHacks adds:

There’s a thought-provoking piece over at Brain Ethics about the role of genetics in violence, and particularly the role of a gene that codes for a type of monoamine oxidase enzyme involved in the breakdown of certain neurotransmitters in the brain.

Judged

It takes just a tenth of a second for people to make judgements about you based on your facial appearance.

Subjects were asked to rate attractiveness, likeability, competence, trustworthiness, and aggressiveness of faces after looking at their photos for just 100ms.

The ratings they gave the faces correlated strongly with ratings given by other students who were allowed as long as they wanted to rate the faces. The strongest correlation was for trustworthiness.
“Maybe as soon as a face is there, you know whether to trust it”, the researchers surmised.

Inking an egg

british egg logoThe age-old argument over the best way to cook the perfect boiled egg could be a thing of the past thanks to a new hi-tech ink logo going on shells.

After cooking begins, an invisible, temperature-sensitive thermochromic print appears in black to indicate when an egg is soft, medium or hard-boiled.

College in 2056?

“The Future Will Be Different! Why Study?” asks bookofjoe

“What will higher education look like in 50 years? If you weren’t in Honolulu a couple of weeks ago, you might not know. Alas, I wasn’t there either. But a glance at the panels of a conference convened there — called “The Campus of the Future” — offers a clue: College in the coming decades will have even less to do with learning than it does now.”

Early Infections Cause Chronic Illnesses

Even if one does not die while infected the infectious diseases take their toll and accelerate aging in a number of ways.

First off, the pathogens directly do damage to the body.

Second, the immune system’s response does damage. In the process of attacking pathogens the immune response causes collateral damage to human tissue. Chemical compounds released by immune cells do damage to our own cells.

Third, infection reduces our ability to stay nourished due to decreased appetite, diarrhea, decreased ability to do activities that bring in food, and other mechanisms.

Therefore a reduction in infectious disease exposure has reduced the rate at which our bodies accumulate damage.

Gina Kolata of the New York Times has written a great article surveying the building body of evidence which shows earlier generations got classic diseases of old age sooner and did so due to infections while very young and poorer nutrition. (and I strongly urge you to read the full article)

New research from around the world has begun to reveal a picture of humans today that is so different from what it was in the past that scientists say they are startled. Over the past 100 years, says one researcher, Robert W. Fogel of the University of Chicago, humans in the industrialized world have undergone “a form of evolution that is unique not only to humankind, but unique among the 7,000 or so generations of humans who have ever inhabited the earth.”

We humans alive today are physically way different on average as compared to previous generations.

In previous centuries heart disease, lung disease, and other ailments showed up decades earlier in human lives.

The biggest surprise emerging from the new studies is that many chronic ailments like heart disease, lung disease and arthritis are occurring an average of 10 to 25 years later than they used to. There is also less disability among older people today, according to a federal study that directly measures it. And that is not just because medical treatments like cataract surgery keep people functioning. Human bodies are simply not breaking down the way they did before.

What is most interesting about these results are the suspected causes: events in the womb and while still quite young can set people up for chronic diseases decades later.

The proposed reasons are as unexpected as the changes themselves. Improved medical care is only part of the explanation; studies suggest that the effects seem to have been set in motion by events early in life, even in the womb, that show up in middle and old age.

“What happens before the age of 2 has a permanent, lasting effect on your health, and that includes aging,” said Dr. David J. P. Barker, a professor of medicine at Oregon Health and Science University in Portland and a professor of epidemiology at the University of Southampton in England.

But it is too late for us to go back in time and tell our mothers to avoid people with colds and flus and other infectious diseases. Our bodies are damaged even from before birth.

no heartburn and no pain?

Why Stomach Acid is Good For You by Wright and Lenard.

Interesting theory on stomach function, stomach acid, and the damage done by antacids and acid suppressing drugs. If you are taking Prevacid, Nexium, Prilosec — you must read this book. It may or may not be right but it is a view you should understand for yourself.

The core of it is this — heartburn caused by acid reflux is actually a symptom of too little stomach acid, and the downstream effects on your helf of having too little acid and thus incorrectly digesting food are tremendous. The heavily-marketed treatment of eliminating stomach acid does more harm over your lifetime than good.

Brilliant articulation of how to think about the future

A couple years ago, I was talking the Institute’s Bob Johansen about wisdom, and he explained that – to deal with an uncertain future and still move forward – they advise people to have “strong opinions, which are weakly held.”

TOURBUS Volume 12, Number 04

On with the show…

Dale’s Cone of Nonesense
Audience: Educators, Librarians, and Trainers
———————————————–

Since many Tourbus riders are also educators or librarians, I thought
I’d don my powder blue academic hood [see http://tinyurl.com/qjubv ]
and share with you some interesting academic research. There is a
concept in education called “Dale’s Cone of Experience” that states
that people generally remember:

10% of what they read
20% of what they hear
30% of what they see
50% of what they hear and see
70% of what they say or write
90% of what they as they do a thing

Often displayed graphically as a cone — see
http://teacherworld.com/dalescone.gif — Dale’s Cone has had a
profound impact on the way we teach both children and adults.

And it is a complete and total fraud.

No, really. Will Thalheimer at Work-Learning Research delved into
Dale’s Cone and discovered that:

1. While Edgar Dale indeed did indeed create a model of the
concreteness of various audio-visual material back in 1946,
the model contained no numbers and no research was conducted
to create the model. Dale’s Cone was just a hunch, albeit an
educated hunch, one that Dale warned shouldn’t be taken too
literally.

2. The percentages — ‘people generally remember 10% of what they
read’ and so on — were most likely added to Dale’s Cone by an
employee of the Mobil Oil company in the late 1960s. These
percentages have since been discredited.

You can see Thalheimer’s complete report online at

http://www.work-learning.com/chigraph.htm

It’s an eye-opening read, especially if you’re an educator, librarian
or trainer. Let me also put in a plug for Thalheimer’s blog at

http://www.willatworklearning.com/

While I’ve known about Thalheimer’s investigation into Dale’s Cone
for a couple of years now, I’ve only recently discovered his blog.
It contains a collection of “research-based commentary on learning,
performance, and the industry thereof.”

'Man maps' link love and real estate

This is one even the writers of “Sex in the City” couldn’t dream up -– a map to identify neighborhoods with the most rich men. It’s real estate meets Mr. Right in the form of online “man maps.”

The maps are the brainchild of Kelly Kreth, a divorced New York City publicist who represents an online real estate firm called PropertyShark.com.

“I had asked the founder of Property Shark if he would construct a map with all his city-centric data of where all the rich single men are so I could find a date,” says Kreth.

Granite Frisbee

There are 1000s & 1000s of, I swear, perfect skipping stones in the delta bed of the Eel River.

I’m astounded. I would never have imagined anything like it. Every footstep reveals a handful of granite frisbee to spin. There can’t be another factory like it anywhere.

I’m stunned there isn’t a global championship event each year. A regional charity competition. Speaking of which, the Fortuna AutoExpo was a kick. Many many sweet rigs under the perfect coastal sun.

google offers up some fun entries with ‘perfect skipping stone‘, for instance, a physicist has answered his son’s quest for the perfect skipping stone that maximizes its number of bounces on a lake,

Mathematically speaking, the number of bounces equals
velocity squared divided by gravity and the distance.

In 1992, a man in Blanco River, Texas,
set the world record for the most bounces: 38.


Update:
In 2002, Kurt “Mountain Man” Steiner took the record to 40. But in the summer of 2007, Guinness certified a new record of an outstanding 51 skips by Russell “Rock Bottom” Byars.

How the nation changes

This study indicates that there are 35.2 million immigrants — legal and illegal — living in the US making it the largest immigrant population in US history.

The current immigration boom is two and a half times the 13.5 million immigrants in 1910.

Most landlords in America allow pets

The great majority of Americans own pets.
Caring for a pet is a signature of responsibility.
Pets provide an essential part of our humanity.

I’ve travelled many places.
I’m in the north coast of California now.
This area is unique.
Most nearby landlords condemn pets.

It is only a local fashion.
And it’s a thoughtless policy.

Directional fire alarms

times have really changed

Reputation is many things. For our nation, here’s one insight about how we’re doing.

…times have really changed.
Sellers or suppliers are finding that payments are not guaranteed even within the system in North America.

Many distributors, contractors, or buyers in North America are not even getting paid themselves by their own customers and thus can not afford to pay the supplier.

Bankruptcies and terms such as Chapter 11 are being learned by foreigners when they find out that the company they sold to cannot and will not pay the supplier at all.

Suppliers are finding that they do not understand the legal system or ways of collecting money from their American customers. Some suppliers are now changing their terms of sales to Letters of Credit only to find out that their competitors have not.

Since it is still a buyer’s market and hundreds of suppliers are selling with open account terms, how does one protect his investment and sell in North America?

Some suppliers are just backing out and saying to themselves “Let us sell to South America or the Far East where buyers pay by Letter of Credit or some guarantee of payment; plus these buyers are not so demanding.

Coffins for humanity

EveryBody Special is a new, low-cost wooden coffin created to meet extreme demand during emergency situations.

Designed by Dutch EveryBody Coffins, the EveryBody Special is a modular coffin that’s extremely easy to assemble. No tools, nails or screws are required – the pieces just click together. The standard material used is 12 mm multilayered wood, and more environmentally friendly options are also available.

Since they’re lightweight and packaged in flat-packs (Ikea-style), transporting EveryBody coffins is very cost efficient: up to 570 extra large (XL) caskets fit into a 20 foot container. Combined with their easy assembly, this makes the coffins highly suitable for burial and cremation in disaster areas and epidemic situations. The company hopes to offer a more dignified, humane alternative to plastic body bags that are often the only option when large-scale disaster strikes.

Besides selling to governmental and aid organisations, EveryBody is also offering its product to commercial distributors in those regions where consumers will welcome a low-cost alternative to expensive caskets. As we’ve pointed out before, everything can be reinvented!
