2014 Ranking of the World’s Best Research Universities

Shanghai’s Jiao Tong University produces an annual ranking of research universities. The methodology values publications and faculty awards (Nobel and Fields) which belies the focus on ranking research not for example the quality of education provided.

You could argue one measure does partially address teaching as the Nobel and Fields prizes to alumni are created to the institution (that is separate from a measure of faculty that receive those honors). I would agree it partially measure the education though it also measures the ability of that school to attract the absolute best candidates (whether they would have been just as successful going elsewhere is a fair question).

Results from the 2014 rankings of top 500 universities with the number of schools by country:

location Top 100 % of World
Population
% of World GDP % of top 500
USA 52     4.5%   22.2%  29.2%
United Kingdom   8  0.9  3.5 7.6
Germany   4  1.1  5.0 7.8
Canada   4  0.5  2.4 4.2
France   4  0.9  3.8 4.2
Japan   3  1.8  7.8 3.8
Australia   4  0.3  1.5 3.8
China   0  19.2  11.7 8.8
Netherlands   4  0.2  1.3 2.6
Sweden   4  0.1  0.8 2.2
Switzerland   5  0.1  0.8 1.4
South Korea   0  .7  1.7 2.0
India   0  17.0  1.9 0.2

The top countries for top 100 and top 500 schools are listed above, but I skip over many after the top 7 or 8 to include a few countries I like to watch, see the ranking site for the full list. Country population and GDP data were taken from the World Development Indicators 2013, by the World Bank.

There is little change in top 100 since 2008, which I think is a good sign, it wouldn’t make much sense to have radical shifts quickly in this type of ranking. The USA lost 2 schools in the top 100, UK lost 3, Germany lost 2, Switzerland gained 2, Netherlands gain 2…

There is more change in the top 500 where changes are more sensible (there is probably not much separating schools ranked in the 300’s from those in the 500’s so variation and strong pushes (from countries like China) can have an impact. China gained 14 more schools in the top 500. China’s GDP also increased from 6.6% of global GDP to 11.7%.

Ranking Countries by Scientific Publication Citations: USA, UK, Germany…

The SCImago Journal and Country Rank provides journal and country scientific indicators developed from the information contained in the Scopus database. I posted about this previously (in 2014, 2011 and 2008).

The data in the post is based on their data from 1996 through 2013. The web site also lets you look at these ranking by very specific categories. For example biotechnology #1 USA, #2 Germany, #3 UK, #4 Japan, #12 China or human computer interaction #1 USA, #2 Germany, #3 UK #4 Japan, #13 China).

I like looking at data and country comparisons but in doing so it is wise to remember this is the results of a calculation that is interesting but hardly definative. We don’t have the ability to measure the true scientific research output by country.

The table shows the top 6 countries by h-index and then some others I chose to list.

Math Education Results Show China, Singapore, Korea and Japan Leading

The most comprehenvise comparison of student achievement in math and science around the globe undertaken by the Organisation for Economic Co-operation and Development (OECD). The 2012 Program for International Student Assessment (PISA) focuses on math understanding of 15 year olds (the 2014 report will focus on science). The 2009 report focused on the results of science education student achievement around the globe.

2012 results for the math portion (rank – country – mean score)(I am not listing all countries):

  • 1 – Singapore – 573
  • 2 – Korea – 554
  • 3 – Japan – 536
  • 5 – Switzerland – 531
  • 6 – Netherlands – 523
  • 7 – Estonia – 521
  • 8 – Finland – 519
  • 9 – Canada – 518
  • 12 – Germany – 514
  • 24 – UK – 494 (this is also the OECD average)
  • 34 – USA – 481
  • 49 – Malaysia – 421
  • 50 – Mexico – 413

All 34 OECD member countries and 31 partner countries and economies participated in PISA 2012, representing more than 80% of the world economy. Portions of China participated and did very well including Shanghai-China (highest mean score of 613 points – if you ranked that as a country, I ignored these “regional results” in the ranks I shown here), Hong Kong-China (561, 3rd if including countries and regions together), Chinese Taipei [Taiwan] (560, 4th), Macao-China (538, 6th).

Boys perform better than girls in mathematics in 38 out of the 65 countries and economies that participated in PISA 2012, and girls outperform boys in 5 countries.

Toyota Human Support Robot

Toyota continues to develop their partner robot initiative. Demographics in Japan make a compelling case for the need to provide solutions to those who need assistance to support independent living.

The aim is to contribute to the maintenance and improvement of quality of life.

In cooperation of the Yokohama Rehabilitation Center, Toyota conducted experiments for disabled people, using HSR in their homes, in 2011. Toyota has been integrating the feedback to the design, based on actual user experience.

The Human Support Robot (HSR) can pick up something on and bring it to the person. Also it can do small tasks such as opening the curtains.

Controlling the robot can be done easily, by using the voice recognition function or using a tablet control. In addition, Toyota is designing it to directly assist the person, helping them get into and out of a bathtub, for example.

They are also developing new features for remote viewing and remote operation (to provide off site help to make the robot more useful). They are working with health care professionals, including nurses, and research institutions aimed at practical use for such a robot.

Toyota, along with several other Japanese companies, continue to invest a great deal to create personal care robots.

Mitsubishi Uses a Sled of Bubbles To Improve Ship Efficiency

Mitsubishi completed the conceptual design of a new container ship; this eco-ship achieves a 25% decrease in CO2 emissions over existing ships. Three, of these ships, with the Mitsubishi Air Lubrication System (MALS), are being built now (they should be completed in 2014).

In addition to blowers to create air bubbles under the vessel bottom, the three grain carriers will also feature a newly designed bow shape that will reduce wave-making resistances. For propulsion, the ship adopts a system to effectively convert the main engine power into propulsion power by positioning fins forward of the propellers and placing particular grooves in the propeller boss cap.

Using “eco-ships” to substantially reduce CO2 emissions from maritime transport

Reducing the frictional drag on the hull of a ship saves fuel and lowers CO2 emissions. To achieve this, MHI developed the Mitsubishi Air Lubrication System (MALS), which reduces frictional drag by introducing air bubbles by air blower into the water around the bottom of a ship’s hull, covering the ship in bubbles. By arranging the air blowhole location and shape and controlling the air volume, the lubrication effect has been enhanced, reducing CO2 emissions per container transportation by 10 percent.

This system has already been introduced on module carriers, and has been proven to reduce CO2 emissions significantly.

YouTube SpaceLab Experiment Competition

YouTube SpaceLab is an open competition inviting 14 – 18 year olds (anywhere in the world) to create an idea for a science experiment in space. You don’t have to actually do the experiment, you just have to record yourself explaining it.

Entries must have be submitted on YouTube by 07:59 GMT on December 8th.

The winning experiments will be conducted on the International Space Station (ISS) and beamed live on YouTube for the whole planet to see.

Winners get the choice to either watch the rocket blast off with your idea on it in Japan or take a specially tailored astronaut training course in Russia when you turn 18. There are other amazing prizes for the runners-up too.

Here is an example entry from 3 students in UK on an experiment to learn about quorum sensing by bacteria in the micro gravity of space.

Driving Via Direct Signals from the Brain

Last year we learned of Google’s Self Driving Car, which is actually making great progress in the real world (cool). And a few years ago I wrote about Toyota’s wheelchair you control with your mind. Now Nissan is looking at cars that you drive aided by accessing brain signals.

This idea is a bit scary to me, the self driving car is less so. But it is great to see us pushing the engineering boundaries forward. It is such a shame that the huge economic failures in the USA, Europe and Japan are rightly grabbing much of the attention these days. If we just reduced the waste and corruption in the political and financial systems it would allow us to take more joy is the great time we do for awesome engineering breakthroughs. Still, if we can try to block out those painful economic realities, these types of breakthroughs are really cool.

The webcast shows the work of the Artificial Intelligence Group of the Freie Universität Berlin in Germany (BrainDriver).

Bleeding Heart Flowers

photo of some bleeding heart flowers

One the first flowers to bloom in my yard this year are some bleeding heart flowers (shown the photo). If I remember right, I planted them last year. I love perennials: I just plant them once and then get to keep enjoying them. I also find that some plants that are supposedly annuals seem to keep coming back (I think the plant must just manage to hang on, even if they often don’t, and so are called annuals). I enjoy gardening a bit, but don’t really spend enough time to know much about it. I just do as much as I feel like – and often am so busy that amounts to not much.

Also known as Lamprocapnos spectabilis they are a rhizomatous perennial plant native to eastern Asia from Siberia south to Japan.

Top Countries for Science and Math Education: Finland, Hong Kong and Korea

The 2009 Programme for International Student Assessment (PISA)* report has been released. The report examines the science of 15 year olds from 57 countries in math, science and reading. The main focus of PISA 2009 was reading. The survey also updated performance assessments in mathematics and science.

The Asian countries continue to do very well for several reason including tutoring; they have even turned tutors into rock stars earning millions of dollars. The results show that the focus on student achievement in sciences has had an impact in Asia.

The emphasis is on mastering processes, understanding concepts and functioning in various contexts within each assessment area. the PISA 2012 survey will return to mathematics as the major assessment area, PISA 2015 will focus on science.

Results for the Science portion (rank – country – mean score)(I am not listing all countries):

  • 1 – Finland – 554
  • 2 – Hong Kong – 549
  • 3 – Japan – 539

Honda U3-X Personal Transport

Honda and Toyota continue to develop personal transport and personal robotics assistance products. While other car companies can barely stay in business Honda and Toyota not only are doing well (even if Toyota will lose money this year) they are investing in the future and pushing strong engineering programs. I must say the personal transportation devices seem less than awesome to me though this video does make the Honda U3-X seem reasonable – better than the Toyota Winglet looked.

Honda unveiled U3-X, a compact experimental device that fits comfortably between the rider’s legs, to provide free movement in all directions – forward, backward, side-to-side, and diagonally. Honda will continue research and development of the device including experiments in a real-world environment to verify the practicality of the device.

This new personal mobility device makes it possible to adjust speed and move, turn and stop in all directions when the rider leans the upper body to shift body weight. This was achieved through application of advanced technologies including Honda’s balance control technology, which was developed through the robotics research of ASIMO, Honda’s bipedal humanoid robot, and the world’s first omni-directional driving wheel system (Honda Omni Traction Drive System, or HOT Drive System), which enables movement in all directions, including not only forward and backward, but also directly to the right and left and diagonally. In addition, this compact size and one-wheel-drive personal mobility device was designed to be friendly to the user and people around it by making it easier for the rider to reach the ground from the footrest and placing the rider on roughly the same eye level as other people or pedestrians.
