Broken Window Theory Bolstered with Experiments

The broken window theory is that as the visible deterioration of an area (broken windows, graffiti, lettering…) takes place, crime will increase. And that this starts a cycle of decline for the area feeds upon itself (a negatively reinforcing loop in system thinking parlance). The theory was put forth in an article in The Atlantic in 1982 by George L. Kelling and James Q. Wilson.

Criminology Can the can, The Economist

Kees Keizer and his colleagues at the University of Groningen deliberately created such settings as a part of a series of experiments designed to discover if signs of vandalism, litter and low-level lawbreaking could change the way people behave.

The most dramatic result, though, was the one that showed a doubling in the number of people who were prepared to steal in a condition of disorder. In this case an envelope with a €5 ($6) note inside (and the note clearly visible through the address window) was left sticking out of a post box. In a condition of order, 13% of those passing took the envelope (instead of leaving it or pushing it into the box). But if the post box was covered in graffiti, 27% did. Even if the post box had no graffiti on it, but the area around it was littered with paper, orange peel, cigarette butts and empty cans, 25% still took the envelope.

The researchers’ conclusion is that one example of disorder, like graffiti or littering, can indeed encourage another, like stealing. Dr Kelling was right. The message for policymakers and police officers is that clearing up graffiti or littering promptly could help fight the spread of crime.

Genes Counter a Bacterial Attack

Gene against bacterial attack unravelled

Humans have an innate defence system against deadly bacteria. However, how the step from gene to anti-bacterial effect occurs in the body is not yet known. To date, B. Pseudomallei, a bacterium suitable for bioweapons, had managed to elude medics. It can remain hidden in the human body for many years without being detected by the immune system. The bacteria can suddenly become activated and spread throughout the body, resulting in the patient dying from blood poisoning. AMC physician Joost Wiersinga and the Laboratory for Experimental Internal Medicine discovered which gene-protein combination renders the lethal bacteria B. pseudomallei harmless.

Wiersinga focussed on the so-called Toll-like receptors. These are the proteins that initiate the fight against pathogens. There are currently ten known Toll-like receptors which are located on the outside of immune cells, our body’s defence system. The toll-like receptors jointly function as a 10-figure alarm code. Upon coming into contact with the immune cell each bacterium enters its own Toll code. For known pathogens this sets off an alarm in the immune system and the defence mechanism is activated. Yet B. pseudomallei fools the system by entering the code of a harmless bacterium. As a result the body’s defence system remains on standby.

Yet some people are resistant: they become infected but not ill. Wiersinga found a genetic cause for this resistance. He discovered which toll receptor can fend off B. pseudomallei. He did this by rearing mice DNA in which the gene for Toll2 production was switched on and off. ‘The group where the gene for Toll2 was switched off, survived the bacterial infection’, says Wiersinga. ‘The other receptor that we investigated, Toll4, had no effect – even though for the past ten years medics had regarded this as the most important receptor.’ The ultimate aim of this study is to develop a vaccine.

Huge Tomb Uncovered in Rome

‘Gladiator’ tomb is found in Rome

The tomb of a general thought to have been an inspiration for the main character in the Oscar-winning film Gladiator has been unearthed in Rome.

The tomb was discovered along the northbound Via Flaminia where construction work has been taking place. Many marble columns, inscriptions and decorations have been beautifully preserved thanks to the mud caused by a centuries-old flood of the River Tiber. It is “the most important ancient Roman monument to come to light for 20 or 30 years”, said senior archaeologist Daniela Rossi.

Workers renovating a rugby stadium have uncovered a vast complex of tombs that mimic the houses, blocks and streets of a real city… Meanwhile, archaeologists restoring imperial residences in the heart of ancient Rome are also reported to have found what they believe to be the underground passageway where the Emperor Caligula was murdered by his guards…

59 MPG Toyota iQ Diesel Available in Europe

59 MPG Toyota iQ On Sale In Europe, US Plans Unclear

With lower carbon dioxide emissions than the Prius — around 159 grams of CO2 emitted per mile by the 1.0 liter gas engine and 166 g/mile for the diesel version — not only does the iQ deliver on fuel economy, but its straight-up conventional engine is a pollution winner too.

At just about 9.8 feet long, 5.5 feet wide and 4.9 feet tall, Toyota certainly has pulled of a near engineering miracle with the amount of stuff they’ve crammed into this tiny vehicle. Toyota claims the iQ can fit 3 adults and 1 child “comfortably.”

Toyota expects to sell about 80,000 of them a year in Europe.

I own some Toyota stock (and bought a bit more recently) based on their excellent management and production system and the results they have achieved (so I pay attention to what they are doing – plus I own them because they do things I see as wise so it is a self reinforcing dynamic). Business week recently wrote about Ford’s 65 mpg Diesel Car the U.S. Can’t Have.

I owned Ford stock back when they were adopting Deming based management principles but when they dropped those to pursue short sighted goals and poor management practices I sold and bought Toyota (turned out to be a very wise decision – my mistake was holding Ford too long hoping they would realize their mistake).

Incident in LHC Sector 34

Incident in LHC sector 34

During commissioning (without beam) of the final LHC sector (sector 34) at high current for operation at 5 TeV, an incident occurred at mid-day on Friday 19 September resulting in a large helium leak into the tunnel. Preliminary investigations indicate that the most likely cause of the problem was a faulty electrical connection between two magnets, which probably melted at high current leading to mechanical failure. CERN ’s strict safety regulations ensured that at no time was there any risk to people.

A full investigation is underway, but it is already clear that the sector will have to be warmed up for repairs to take place. This implies a minimum of two months down time for LHC operation. For the same fault, not uncommon in a normally conducting machine, the repair time would be a matter of days.

Symptom of America’s Decline in Particle Physics

Land Of Big Science

Probing more deeply than ever before into the stuff of the universe requires some big hardware. It also requires the political will to lavish money on a project that has no predictable practical return, other than prestige and leadership in the branch of science that delivered just about every major technology of the past hundred years.

Those advances came, in large measure, from the United States. The coming decades may be different.

A third of the scientists working at the LHC hail from outside the 20 states that control CERN. America has contributed 1,000 or so researchers, the largest single contingent from any non-CERN nation.

The U.S. contribution amounts to $500 million—barely 5 percent of the bill. The big bucks have come from the Europeans. Germany is picking up 20 percent of the tab, the British are contributing 17 percent, and the French are giving 14 percent.

The most worrying prospect is that scientists from other countries, who used to flock to the United States to be where the action is, are now heading to Europe instead.

This is a point I have made before. The economic benefits of investing in science are real. The economic benefits of having science and engineering centers of excellence in your country are real. That doesn’t mean you automatically gain economic benefit but it is a huge advantage and opportunity if you act intelligently to make it pay off.

Best Research University Rankings – 2008

The annual ranking of research Universities are available from Shanghai’s Jiao Tong University. The methodology values publications and faculty awards which provides a better ranking of research (rather than teaching). Results from the 2008 rankings of Top 500 Universities worldwide, country representation of the top schools:

location Top 100 % of World
Population
% of World GDP % of top 500
USA 54     4.6%   27.2%  31.6%
United Kingdom 11  0.9  4.9 8.3
Germany   6  1.3  6.0 8.0
Japan   4  2.0  9.0 6.2
Canada   4  0.5  2.6 4.2
Sweden   4  0.1  0.8 2.2
France   3  0.8  4.6 4.6
Switzerland   3  0.1  0.8 1.6
Australia   3  0.3  1.6 3.0
Netherlands   2  0.2  1.4 2.4
Denmark   2  0.1  0.6 0.8
Finland   1  0.1  0.4 1.2
Norway   1  0.1  0.7 0.8
Israel   1  0.1  0.3 1.2
Russia   1  2.2  2.0 0.4
China  20.5  6.6 6.0
India  17.0  1.9 0.4

There is little change in most of the data from last year, which I think is a good sign, it wouldn’t make much sense to have radical shifts over a year in these rankings. Japan lost 2 schools in the top 100, France lost 1. Denmark (Aarhus University) and Australia (University of Sydney) gained 1. Last year there was a tie so there were 101 schools in the top 100.

The most dramatic data I noticed is China’s number of top 500 schools went from 14 to 30, which made me a bit skeptical of what caused that quick change. Looking more closely last year they reported the China top 500 totals as (China 14, China-Taiwan 6 and China-Hong Kong 5). That still gives them an impressive gain of 5 schools.

Singapore has 1 in the 102-151 range. Taiwan has 1 ranked in the 152-200 range, as do Mexico, Korea and Brazil. China has 9 in the 201-302 range (including 3 in Hong Kong). India has 2 in the 303-401 range.

The Brain Hides Information From Us To Prevent Mistakes

The Brain Hides Information From Us To Prevent Mistakes

“The main finding of the study is that it has enabled us to confirm that tactile sensations are initially located unconsciously in anatomical coordinates, but they reach our awareness only when the brain has formed an image of their origin in the spatial coordinates, external to the body,” explained Salvador Soto-Faraco. The coexistence of different spatial reference frames in the brain has been known for some time. So has the fact that confusions between them may result in some cases, such as when we invert the usual anatomical position of some body parts (e.g. when crossing our arms over the body midline). “The brain sorts out problems of this kind rapidly, in a matter of tenths of a second. To do so, however, it has to integrate information arriving in formats that are quite disparate”, Sotoa-Faraco added. “Our research has helped us understand how this process works and how the brain manages spatial realignment when faced with conflict”, he concluded.

Interesting. I think my brain might be hiding more from me lately (like right now where the key to my shed is) :-)

Germany Looking to Kindergarten for Engineering Future

German groups seek next crop of engineers in the kindergarten

Germany’s shortage of engineers has become so acute that some of its leading companies are turning to kindergartens to guarantee future supplies.

Groups such as Siemens and Bosch are among hundreds of companies giving materials and money to kindergartens to try to interest children as young as three in technology and science.

Many European countries from Switzerland to Spain suffer shortages of graduates. But the problem is especially acute in Germany, renowned as a land of engineering. German companies have 95,000 vacancies for engineers and only about 40,000 are trained, according to the engineers’ association.

“It is a new development in that we have seen we need to start very early with children. Starting at school is not good enough – we need to help them to understand as early as possible how things work,” said Maria Schumm-Tschauder, head of Siemens’ Generation21 education programme.

Siemens has provided about 3,000 “discovery boxes” filled with science experiments for three- to six-year-olds to kindergartens throughout Germany, at a cost to the company of €500 (£395) a box. It also trains kindergarten teachers on how to use them as well as providing similar boxes around the world to pre-schools from China and South Africa to Ireland and Colombia.

Germany Bans Chemicals Linked to Bee Deaths

Germany bans chemicals linked to honeybee devastation

Germany has banned a family of pesticides that are blamed for the deaths of millions of honeybees. The German Federal Office of Consumer Protection and Food Safety (BVL) has suspended the registration for eight pesticide seed treatment products used in rapeseed oil and sweetcorn.

The move follows reports from German beekeepers in the Baden-Württemberg region that two thirds of their bees died earlier this month following the application of a pesticide called clothianidin. “It’s a real bee emergency,” said Manfred Hederer, president of the German Professional Beekeepers’ Association. “50-60% of the bees have died on average and some beekeepers have lost all their hives.” Tests on dead bees showed that 99% of those examined had a build-up of clothianidin.

The company says an application error by the seed company which failed to use the glue-like substance that sticks the pesticide to the seed, led to the chemical getting into the air.
