___________________

At Guadalupe Peak, the highest point in Texas at 8,749 feet in Guadalupe Mountains National Park I found a huge city of ladybugs. They covered the bark of many bushes and trees and crawled over rocks (as seen in the photos). They were everywhere. It seems odd to me that they would have such a huge concentration since it would seem like food would then be a problem, but there they were.

Historical Engineering: Hanging Flume

Hanging flumephoto of hanging flume overlook in Colorado, by John Hunter, Creative Commons Attribution.

While driving from Dinosaur National Monument to Mesa Verde National Park last year I passed the sight above with the remnants of a hanging flume. The Montrose Placer Mining Company built a 13 mile canal and flume to deliver water from the San Miguel River for gold mining operations. The last 5 miles of the flume clung to the wall of the canyon itself, running along the cliff face in the photo above (see more photos).

Constructed between 1888 and 1891, the 4 foot deep 5 foot 4 inch wide hanging flume carried 23,640,000 gallons of water in a 24 hour period. The mining operations used water and sluice boxes to separate the gold from lighter materials (dirt and gravel).

The technology was not yet available to pump the water directly from the river at the necessary volume and pressure to wash the gold from the gravel, therefore they constructed the flume to transport the water.

Keeping Out Technology Workers is not a Good Economic Strategy

The barriers between countries, related to jobs, are decreasing. Jobs are more international today than 20 years ago and that trend will continue. People are going to move to different countries to do jobs (especially in science, engineering and advanced technology). The USA has a good market on those jobs (for many reasons). But there is nothing that requires those jobs to be in the USA.

The biggest impact of the USA turning away great scientists and engineers will be that they go to work outside the USA and increase the speed at which the USA loses its place as the leading location for science, engineering and technology work. This is no longer the 1960′s. Back then those turned away by the USA had trouble finding work elsewhere that could compete with the work done in the USA. If the USA wants to isolate ourselves (with 5% of the population) from a fairly open global science and engineering job market, other countries will step in (they already are trying, realizing what a huge economic benefit doing so provides).

Those other countries will be able to put together great centers of science and engineering innovation. Those areas will create great companies that create great jobs. I can understand wanting this to be 1960, but wanting it doesn’t make it happen.

You could go even further and shut off science and engineering students access to USA universities (which are the best in the world). That would put a crimp in plans for a very short while. Soon many professors would move to foreign schools. The foreign schools would need those professors, and offer a great deal of pay. And those professors would need jobs as their schools laid off professors as students disappeared. Granted the best schools and best professors could stay in the USA, but plenty of very good ones would leave.

I just don’t think the idea of closing off the companies in the USA from using foreign workers will work. We are lucky now that, for several reasons, it is still easiest to move people from Germany, India, Korea, Mexico and Brazil all to the USA to work on advanced technology projects. The advantage today however, is much much smaller than it was 30 years ago. Today just moving all those people to some other location, say Singapore, England, Canada or China will work pretty well (and 5 years from now will work much better in whatever locations start to emerge as the leading alternative sites). Making the alternative of setting up centers of excellence outside the USA more appealing is not a good strategy for those in the USA wanting science, engineering and computer programming jobs. We should instead do what we can to encourage more companies in the USA that are centralizing technology excellence in the USA.

USA Losing Scientists and Engineers Educated in the USA

The USA continues to lose ground, in retaining the relative science and engineering strength it has retained for the last 50 plus years. As I have said before this trend is nearly inevitable – the challenge for the USA is to reduce the speed of their decline in relative position.

A new open access report, Losing the World’s Best and Brightest, explores the minds of current foreign science and engineering students that are studying in the USA. This is another in the list of reports on similar topics by Vivek Wadhwa and Richard Freeman. And again they point out the long term economic losses the USA is setting up by failing to retain the talent trained at our universities. It is a problem for the USA and a great benefit for countries like India and China.

“Foreign students receive nearly 60% of all engineering doctorates and more than half of all mathematics, computer sciences, physics and economics doctorates awarded in the United States. These foreign nationals end up making jobs, not taking jobs,” said Wadhwa. “They bring insights into growing global markets and fresh ideas. Research has shown that they even end up boosting innovation by U.S. inventors. Losing them is an economic tragedy.”

According to the study’s findings, very few foreign students would like to stay in the United States permanently—only 6% of Indian, 10 percent of Chinese and 15% of Europeans. And fewer foreign students than the historical norm expressed interest in staying in the United States after they graduate. Only 58% of Indian, 54% of Chinese and 40% of European students wish to stay for several years after graduation. Previous National Science Foundation research has shown 68% of foreigners who received science and engineering doctorates stayed for extended periods of time, including 73% of those who studied computer science. The five-year minimum stay rate was 92% for Chinese students and 85% for Indian students.

The vast majority of foreign student and 85% of Indians and Chinese and 72% of Europeans are concerned about obtaining work visas. 74% of Indians, 76% of Chinese, and 58% of Europeans are also worried about obtaining jobs in their fields. Students appear to be less concerned about getting permanent-resident visas than they are about short-term jobs. Only 38% of Indian students, 55% of Chinese, and 53% of Europeans expressed concerns about obtaining permanent residency in the USA.

On the tonight show yesterday, President Obama said

we need young people, instead of — a smart kid coming out of school, instead of wanting to be an investment banker, we need them to decide they want to be an engineer, they want to be a scientist, they want to be a doctor or a teacher.

And if we’re rewarding those kinds of things that actually contribute to making things and making people’s lives better, that’s going to put our economy on solid footing. We won’t have this kind of bubble-and-bust economy that we’ve gotten so caught up in for the last several years.

Eric Schmidt, Google CEO, recently expressed his frustration with the policies discouraging science and engineering graduates staying in the USA after they complete their education.

That is a brilliant [actually not brilliant at all] strategy take the best people hire them in American universities and then kick them out” It happens. “Its shocking.” It happens. “I know we are fighting against it.” “We America remain, by far the place of choice for education, particularly higher education.”

Thanksgiving, Appropriately

photo of Frew Wube in Ethiopia

This is a post from my Curious Cat Investing and Economics Blog: Financial Thanksgiving. I have tweaked a bit to tie into appropriate technology since that is the related area to me on this blog.

For me, giving back to others is part of my personal financial plan. As I have said most people that are actually able to read this are financially much better off than billions of other people today. At least they have the potential to be if they don’t chose to live beyond their means. Here are some of the ways I give back to others.

Kiva is a wonderful organization and particularly well suited to discuss because they do a great job of using the internet to make the experience rewarding for people looking to help – as I have mentioned before: Reducing Poverty. One of my goals for this blog is to increase the number of readers participating in Kiva – see current Curious Cat Kivans. I have also created a lending team on Kiva. Kiva added a feature that allows people to connect online. When you make a loan you may link you loan to a group.

I actually give more to Trickle Up, I have been giving to them for a long time. They appeal to my same desire to help people help themselves. I believe in the power of capitalism and people to provide long term increases in standards of living. I love the idea of providing support that grows over time. I like investing and reaping the rewards myself later (with investment I make for myself). But I also like to do that with my gifts. I would like to be able to provide opportunities to many people and have many of them take advantage of that to build a better life for themselves, their families and their children.

The photo shows Frew Wube, Haimanot and Melkan (brother and two sisters), an entrepreneur that received a grant from Trickle up. Trickle Up provides grants to entrepreneur, similar to micro loans, except the entrepreneur does not have to pay back the grant. They are able to use the full funds to invest in their business and use all the income they are able to generate to increase their standard of living and re-invest in the business.

Toward a More Open Scientific Culture

Michael Nielsen wrote a great post, The Future of Science, which is also the topic of a book he is writing. He discusses how scientific advancement has often been delayed as those making discoveries did not share them openly. And how 300 years ago scientific journals and reward systems created ways for scientists to be rewarded for publication. And he continues with the need for the process to again change and promote more open sharing of scientific knowledge, which I agree with and have written about previously: Publishers Continue to Fight Open Access to Science, Science Journal Publishers Stay Stupid, The Future of Scholarly Publication, etc..

Why were Hooke, Newton, and their contemporaries so secretive? In fact, up until this time discoveries were routinely kept secret.

This cultural transition was just beginning in the time of Hooke and Newton, but a little over a century later the great physicist Michael Faraday could advise a younger colleague to “Work. Finish. Publish.” The culture of science had changed so that a discovery not published in a scientific journal was not truly complete. Today, when a scientist applies for a job, the most important part of the application is their published scientific papers.

This has been a great advance. Now we need to continue that advance to use the internet to make that publication open and increase the advantage of shared knowledge to society.

The adoption of the journal system was achieved by subsidizing scientists who published their discoveries in journals. This same subsidy now inhibits the adoption of more effective technologies, because it continues to incentivize scientists to share their work in conventional journals, and not in more modern media.

This means: making many more types of content available than just scientific papers; allowing creative reuse and modification of existing work through more open licensing and community norms; making all information not just human readable but also machine readable; providing open APIs to enable the building of additional services on top of the scientific literature, and possibly even multiple layers of increasingly powerful services. Such extreme openness is the ultimate expression of the idea that others may build upon and extend the work of individual scientists in ways they themselves would never have conceived.

To create an open scientific culture that embraces new online tools, two challenging tasks must be achieved: (1) build superb online tools; and (2) cause the cultural changes necessary for those tools to be accepted.

I agree we need to take advantage of the new possibilities to advance the practice of science. His full post is well worth reading.

Bacteria and Efficient Food Digestion

Gut Bacteria May Cause And Fight Disease, Obesity

“We’re all sterile until we’re born,” says Glenn Gibson, a microbiologist at the University of Reading in Britain. “We haven’t got anything in us right up until the time we come into this big, bad, dirty world.”

But as soon as we pass out of the birth canal, when we are fetched by a doctor’s hands, placed in a hospital crib, put on our mother’s breast, when we drag a thumb across a blanket and stick that thumb in our mouths, when we swallow our first soft food, we are invaded by all sorts of bacteria. Once inside, they multiply – until the bacteria inside us outnumber our human cells.

University of Chicago immunologist Alexander Chervonsky, with collaborators from Yale University, recently reported that doses of the right stomach bacteria can stop the development of type 1 diabetes in lab mice. “By changing who is living in our guts, we can prevent type 1 diabetes,” he told The Wall Street Journal.

The bottom line: We now have two sets of genes to think about – the ones we got from our parents and the ones of organisms living inside us. Our parents’ genes we can’t change, but the other set? Now that is one of the newest and most exciting fields in cell biology.

Follow link with related podcast: Gut bacteria may cause and fight, disease, obesity. This whole area of the ecosystem within us and our health I find fascinating. And I fall for confirmation bias on things like becoming inefficient at converting food to energy as a way reduce obesity.

You could have two people sitting down to a bowl of cheerios, they could each eat the same number of cheerios but because of a difference in their gut bacteria one will get more calories than the other.

.

They then gave an example of the difference being 95 calories versus 99 calories. Hardly seems huge but it would add up. Still that is a less amazing difference than I was expecting.

William G. Hunter Award 2008: Ronald Does

The recipient of the 2008 William G. Hunter Award is Ronald Does. The Statistics Division of the American Society for Quality (ASQ) uses the attributes that characterize Bill Hunter’s (my father – John Hunter) career – consultant, educator for practitioners, communicator, and integrator of statistical thinking into other disciplines to decide the recipient. In his acceptance speech Ronald Does said:

The first advice I received from my new colleagues was to read the book by Box, Hunter and Hunter. The reason was clear. Because I was not familiar with industrial statistics I had to learn this from the authors who were really practicing statisticians. It took them years to write this landmark book.

For the past 15 years I have been the managing director of the Institute for Business and Industrial Statistics. This is a consultancy firm owned by the University of Amsterdam. The interaction between scientific research and the application of quality technology via our consultancy work is the core operating principle of the institute. This is reflected in the type of people that work for the institute, all of whom are young professionals having strong ambitions in both the academic world and in business and industry.

The kickoff conference attracted approximately 80 statisticians and statistical practitioners from all over Europe. ENBIS was officially founded in June 2001 as “an autonomous Society having as its objective the development and improvement of statistical methods, and their application, throughout Europe, all this in the widest sense of the words” Since the first meeting membership has grown to about 1300 from nearly all European countries.

Reducing Poverty

photo of Rita Bashnet

Today is blog action day, which this year is focused on poverty. We have highlighted various uses of appropriate technology, many of which help those in poverty improve their lives. Such as: Water Pump Merry-go-Round and Smokeless Stove Uses 80% Less Fuel.

I am also very interested in using micro loans to help entrepreneur improve their lives – I have written about Kiva before. Kiva fellows are funded by Kiva (fellows are unpaid) to go to spend time in the countries Kiva facilitates loans for working with the local partners. This post is about Rita Bashnet (in photo) an entrepreneur from Nepal:

Field visits are by far the best part about being a Kiva Fellow. You’re given the opportunity to hop on a motorbike, hike up a village trail, and actually see the impact of a Kiva loan firsthand.

Five years ago, Ms. Rita took her first loan of NRs. 10,000 (USD $150) and purchased some extra seed and fertilizer in the hopes of expanding her small vegetable patch. With the profits from this initial investment and a second loan from Patan Business and Professional Women (they offer a graduated loan program), she then purchased her first dairy cow.

After hearing about a program that subsidized the installation of methane gas storage tanks, Ms. Rita took another loan and applied for the program. With this new system, she is now able to capture the valuable gas released from her cow’s waste in a simple controlled-release storage tank. Today she no longer purchases gas from the city and can even sell some during times of shortage.

Ms. Rita exemplifies the potential of microfinance. A combination of access to capital and strategic investment has allowed her and her family to drastically improve their economic situation in a short five years.

Great story, and exactly my hope for using capitalism to improve the standard of living for people around the globe.

If you haven’t loaned money through Kiva, please consider it now. If you do (or already have a Kiva page), send me your Kiva lender link and I will add it to Curious Cat Kivans. I would love to add more of our readers to that page.
