Ranking Universities Worldwide

The Webometrics Ranking of World Universities provides another estimate of the top universities. The methodology is far ideal however I still find it interesting. The various attempts to rank schools can provide a general idea of impact of various institutions (though the measures are fairly crude). Still a sensible picture (especially at the country level) can emerge. And the various rankings should be a able to track shifts in the most influential institutions and relative country strength over time. How quickly those rankings track changes will vary depending on the measures used. I would imagine most will lag the “real” changes as it is easy to imagine many measures that would lag. Still, as I have said before, I expect the USA will lose in relative ranking compared to China, India, Japan, Singapore, Mexico…

The ranking methodology used here weighed rankings in: Jiao Tong academic rankings, Essential Science Indicators, Google Scholar, Alexa (a measure of web site visits to universities) and The Times Higher World University Rankings.

Antibiotics Too Often Prescribed for Sinus Woes

This is not one of the more amazing articles, rather one more in the long line of those reporting on the overuse of anti-biotics: Antibiotics Too Often Prescribed for Sinus Woes:

But it’s hard to preach that wisdom to someone with a drippy, hurting sinus who wants immediate relief, Leopold acknowledged. Because more effective drugs are lacking, “patients are desperate, physicians are desperate, and it is not a happy situation,” he said.

I guess I am just out of touch but why do physicians think it is ok to practice bad medicine because people will whine if they try to practice sensible medicine? These stories often tell of doctors that can’t say no to patients even if it means going against what is the best medical advice. Is it any wonder that helath costs continue to escalate, now totaling 16% of GDP, with such practices accepted? How hard is it to say, yeah great you want x drug, that is not medically advisable and is only available by prescription because it is not advisable for people to decide they need it but rather physicians are suppose to make that decision.

And so the physician often makes the practical choice of giving what the patient wants, with a chance of relief, over the more abstract issue of antibiotic resistance, he said.

I understand this reality. I just find it very sad that that professionals sacrifice the future to today’s ignorance and short sightedness. I wish physicians would not reward those demanding they get what they want today since they are simultaneously condemning others to suffer the consequences of such decisions.

But I also want us to stop spending our grandchildren’s money today. Still the politicians act just like the physicians choosing to give the voters what they want today and let someone else deal with the consequences later. Current USA federal deficit: $8,841,291,672,873 (see live debt clock), $29,349 for every citizen of the USA. It seems pretty obvious the same willingness to sacrifice the future for an easier life today is at the root of the actions by both doctors and politicians. Thankfully some are trying to counter this behavior, by both parties, to varying success.

China Leads in Producing Post Graduate Engineers

Highly recommended for those interested in the macro view of engineering education in the USA, India and China. Where the Engineers Are is an excellent article building off the work mentioned in previous posts including: Worldwide Science and Engineering Doctoral Degree Data, USA Under Counting Engineering Graduates and House Testimony on Engineering Education. The data they have collected and interpreted shows that China has moved ahead of the USA in doctoral degrees in engineering and India has not been growing there doctoral graduate counts.

In the United States, close to 60% of engineering PhD degrees awarded annually are currently earned by foreign nationals, according to data from the American Society for Engineering Education. Indian and Chinese students are the dominant foreign student groups. Data for 2005 that we obtained from the Chinese government show that 30% of all Chinese students studying abroad returned home after their education, and various sources report that this number is steadily increasing. Our interviews with business executives in India and China confirmed this trend.

The bottom line is that China is racing ahead of the United States and India in its production of engineering and technology PhD’s and in its ability to perform basic research. India is in particularly bad shape, as it does not appear to be producing the numbers of PhD’s needed even to staff its growing universities.

FDA May Make Decision That Will Speed Antibiotic Drug Resistance

FDA Rules Override Warnings About Drug:

The government is on track to approve a new antibiotic to treat a pneumonia-like disease in cattle, despite warnings from health groups and a majority of the agency’s own expert advisers that the decision will be dangerous for people. The drug, called cefquinome, belongs to a class of highly potent antibiotics that are among medicine’s last defenses against several serious human infections. No drug from that class has been approved in the United States for use in animals.

This is why it is so important for government decisions that require scientific knowledge be made by knowledgeable scientists.

But Sundlof said that under FDA rules, those decisions must be left up to veterinarians unless there is clear evidence that wider use is causing harm.

“That is our policy” is not a good excuse for endangering public health. The dangers of anti-biotic resistance are obvious, well known, we see the results of bad decisions in the past creating havoc today and still government wants to act as though the inevitable consequences of their actions are somehow out of their hands. A policy that will lead to the deaths of many people should be fought. If you want to claim this policy will not do that, then make that argument. Don’t claim some policy prohibits you from saving lives.

Democratic/Republican forms of government give politicians oversight over bureaucracy to guide decisions for the public good. When politicians don’t understand basic science (in this day and age – when decisions require that understanding) that can lead to very dangerous policies. You would think that adults would be able to understand that just because consequences will be delayed a few years that doesn’t mean you should allow special interests to get what they want today. But the deficit (nearly $8,800,000,000,000 for the federal government now) provides a visible sign how much they care about future consequences of their actions. Combine that with little scientific understanding and that is not a prescription for good decisions.

Correlation is Not Causation

Why so much medical research is rot:

People born under the astrological sign of Leo are 15% more likely to be admitted to hospital with gastric bleeding than those born under the other 11 signs. Sagittarians are 38% more likely than others to land up there because of a broken arm. Those are the conclusions that many medical researchers would be forced to make from a set of data presented to the American Association for the Advancement of Science by Peter Austin of the Institute for Clinical Evaluative Sciences in Toronto. At least, they would be forced to draw them if they applied the lax statistical methods of their own work to the records of hospital admissions in Ontario, Canada, used by Dr Austin.

Dr Austin, of course, does not draw those conclusions. His point was to shock medical researchers into using better statistics, because the ones they routinely employ today run the risk of identifying relationships when, in fact, there are none. He also wanted to explain why so many health claims that look important when they are first made are not substantiated in later studies.

As I said in, Seeing Patterns Where None Exists: “Page 8 of Statistics for Experimenters by George Box, William Hunter (my father) and Stu Hunter (no relation) shows a graph of the population (of people) versus the number of storks which shows a high correlation. “Although in this example few would be led to hypothesize that the increase in the number of storks caused the observed increase in population, investigators are sometimes guilty of this kind of mistake in other contexts.'”

Skin Bacteria

Close Look at Human Arm Finds Host of Microbes:

“The skin is home to a virtual zoo,” said Blaser, a microbiologist who last week published online the first molecular analysis of the bacteria living on one small patch of human skin. “We’re just beginning to explore it.” The analysis revealed that human skin is populated by a diverse assortment of bacteria, including many previously unknown species, offering the first detailed peek at this potentially crucial ecosystem.

The work is part of a broader effort by a small coterie of scientists to better understand the microbial world that populates the human body. Virtually every orifice and the digestive tract are swarming with bacteria, fungi and other microbes. By some estimates, only one out of every 10 cells in the body is human.

Blaser’s team swabbed an area of skin about the size of silver dollar on the right and left forearms of three healthy men and three healthy women. They then used sophisticated molecular techniques to amplify and analyze fragments of bacterial DNA captured by the swabs. The analysis revealed 182 species, the researchers reported. Of those, 30 had never been seen. They identified an additional 65 species when they sampled four of the volunteers eight to 10 months later, including 14 new species.

Cancer Cure – Not so Fast

Follow up on Cheap, Safe Cancer Drug?: In which my words will be misinterpreted as “proof” that I am a “pharma shill”:

This drug has only been tested in cell culture and rats. Yes, the results were promising there, but that does not–I repeat, does not– mean the results will translate to humans. In fact, most likely, they will not. Those of us who’ve been in the cancer field a while know that all too common are drugs that kill tumors in the Petrie dish and in mice or rats but fail to be nearly as impressive when tested in humans.

Perhaps the blog post I quote above just resonates with me (see: confirmation bias). To me,it supports my contention in my “Cheap, Safe Cancer Drug?” post, though much more effectively and with supporting evidence. But this is my blog so I get to quote whoever I want, and it isn’t surprising I find those that share my thoughts to be the most compelling 🙂 Anyway the post I quote is definitely worth reading.

Educating the Engineer of 2020: NAE Report

Educating the Engineer of 2020:

The BS degree should be considered as a pre-engineering or “engineer in training” degree.

I am not convinced of this idea. It seems to me a BS degrees in engineering should be a full degree not some “pre” degree like pre-law. Obviously no engineering degree is an invitation to stop learning; life long learning is a requirement whether the engineering degree is earned in 4, 6, 8… years. Improving the life long learning methods is where effort should be focused in my opinion not in making the original degree take longer to earn.

The engineering education establishment should participate in efforts to improve public understanding of engineering and the technology literacy of the public and efforts to improve math, science and engineering education at the K-12 level.
NSF should collect or assist collection of data on program approach and student outcomes for engineering departments/schools so prospective freshman can

These seem like good ideas to me.

Eat food. Not too much. Mostly plants.

Excellent articles on eating healthy but also provides a nice insight in the practice scientific inquiry: Unhappy Meals by Michael Pollan:

Eat food. Not too much. Mostly plants. That, more or less, is the short answer to the supposedly incredibly complicated and confusing question of what we humans should eat in order to be maximally healthy.

That is the advice on how to eat more healthfully by Michael Pollan the author of The Omnivore’s Dilemma

If nutritional scientists know this, why do they do it anyway? Because a nutrient bias is built into the way science is done: scientists need individual variables they can isolate. Yet even the simplest food is a hopelessly complex thing to study, a virtual wilderness of chemical compounds, many of which exist in complex and dynamic relation to one another, and all of which together are in the process of changing from one state to another. So if you’re a nutritional scientist, you do the only thing you can do, given the tools at your disposal: break the thing down into its component parts and study those one by one, even if that means ignoring complex interactions and contexts, as well as the fact that the whole may be more than, or just different from, the sum of its parts. This is what we mean by reductionist science.

Interactions are critical in many experiments. That is why multi-factor experimentation is so important (One-Factor-at-a-Time Versus Designed Experiments) though even using these techniques the complexity of interactions provides an incredibly challenging environment.

Science, Engineering and the Future of the American Economy

9 leaders (Craig Barrett, Charles Vest, Scott McNealy, Gururaj “Desh” Deshpande, Judith Rodin, Rick Rashid, Nick Donofrio, Dr. Ralph Wyndrum Jr. and Lou Dobbs) share their thoughts in Keeping Research and Leadership at Home by Vivek Wadhwa:

[several] stress the need to improve K-12 education, encourage students to study more math and engineering, bring in the best and brightest talent from around the world, and up the ante in basic research.

Craig Barrett, Intel chairman – Currently we have lost the race in K-12 education, we are losing our position as a top educator of science, technology, engineering and mathematics students, we are losing our lead in university research, and we have our head in the sand on government policy.

Gururaj “Desh” Deshpande, Sycamore Networks co-founder and chairman – We believe that all of this greatly increases the chances of a particular innovation having impact. Such sophisticated systems can only be developed in the U.S. because it is the only country with both flexible thinking and free markets.

Charles Vest, former president of MIT, president-elect of the National Academy of Engineering – We’re on top, but our share of the world’s R&D spending, new patents, scientific publications, researchers, and BA and PhD. degrees in science and engineering are all dropping. We need to start right now to strengthen investment in basic research, get serious about K-12 education, especially in math and science, and attract more of our best and brightest young men and women into what will be crucial and exciting careers in engineering and science.
