High-School Social Skills Predict Better Earnings than Test Scores

High-School Social Skills Predict Better Earnings than Test Scores

Ten years after graduation, high-school students who had been rated as conscientious and cooperative by their teachers were earning more than classmates who had similar test scores but fewer social skills, said a new University of Illinois study.

The study’s findings challenge the idea that racial, ethnic, and socioeconomic gaps in educational attainment and earnings can be narrowed solely by emphasizing cognitive skills, said Christy Lleras, a University of Illinois assistant professor of human and community development.

“It’s important to note that good schools do more than teach reading, writing, and math. They socialize students and provide the kinds of learning opportunities that help them to become good citizens and to be successful in the labor market,” she said.

“Unless we address the differences in school climates and curriculum that foster good work habits and other social skills, we’re doing a huge disservice to low-income kids who may be entering the labor market right after high school, especially in our increasingly service-oriented economy,” Lleras added.

The University of Illinois study analyzed data from the National Educational Longitudinal Study, which followed a diverse group of 11,000 tenth graders for 10 years, tracking not only their scores on standard achievement tests but teacher appraisals of such qualities as the students’ work habits, their ability to relate well to peers, and their participation in extracurricular activities, a proxy for the ability to interact well with both students and adults.

The teachers’ assessments were then compared with the students’ self-reported educational attainments and earnings 10 years after high-school graduation. Even after controlling for students’ achievement test scores, family socioeconomic status, and educational attainment, Lleras found that such social skills as conscientiousness, cooperativeness, and motivation were as important as test scores for success in the workplace.

Reducing Poverty

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.

Mentors Prepare Women for Construction Career

Mentors prepare women for construction career

Now Cavitt and other women in the construction school, a part of ASU’s Ira A. Fulton School of Engineering, can give themselves another advantage: Learning from pioneering women who have already risen to leadership positions in the business.

The school recently established its Advancing Women in Construction program, a key part of which is a mentorship project. More than 70 women – and several men – in the construction industry in the greater Phoenix area have signed on to mentor female students and provide them an inside look at life in the industry.
…
plan to increase female enrollment from less than 15 percent of total enrollment to 30 percent – or about 200 female students – within five years.

Cavitt says her favorite things about the school’s construction management program are the opportunities to learn beyond the classroom, such as internships and building-project competitions between construction students at other universities. She expects the mentoring program to add significantly to the value of her college education. “I’m excited to learn about the real-world business of construction from women who have been successful at it for many years,” she says.

Silk E.coli Sensors

“Edible Optics” Could Make Food Safer

Scientists at Tufts University’s School of Engineering have demonstrated for the first time that it is possible to design such “living” optical elements that could enable an entirely new class of sensors. These sensors would combine sophisticated nanoscale optics with biological readout functions, be biocompatible and biodegradable, and be manufactured and stored at room temperatures without use of toxic chemicals. The Tufts team used fibers from silkworms to develop the platform devices.
…
The possibility of integrating optical readout and biological function in a single biocompatible device unconstrained by these limitations is tantalizing. Silk optics has captured the interest of the Defense Department, which has funded and been instrumental in enabling rapid progress on the topic. The Defense Advanced Research Projects Agency (DARPA) awarded Tufts a research contract in 2007 and is funding Tufts and others on groundbreaking projects that could someday result in biodegradable optical sensing communications technology.
…
To form the devices, Tufts scientists boiled cocoons of the Bombyx mori silkworm in a water solution and extracted the glue-like sericin proteins. The purified silk protein solution was ultimately poured onto negative molds of ruled and holographic diffraction gratings with spacing as fine as 3600 grooves/mm.
…
The Tufts team embedded three very different biological agents in the silk solution: a protein (hemoglobin), an enzyme (horseradish peroxidase) and an organic pH indicator (phenol red). In the hardened silk optical element, all three agents maintained their activity for long periods when simply stored on a shelf. “We have optical devices embedded with enzymes that are still active after almost a year of storage at room temperature.

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).

The Rush to Save Timbuktu’s Crumbling Manuscripts

Fabled Timbuktu, once the site of the world’s southernmost Islamic university, harbors thousands upon thousands of long-forgotten manuscripts. A dozen academic instutions from around the world are now working frantically to save and evaluate the crumbling documents.
…
The Ahmed Baba Library alone contains more than 20,000 manuscripts, including works on herbal medicine and mathematics, yellowed volumes of poetry, music and Islamic law. Some are adorned with gilded letters, while others are written in the language of the Tuareg tribes. The contents remain a mystery.

Manuscript hunters are now scouring the environs of Timbuktu, descending into dark, clay basements and climbing up into attics. Twenty-four family-owned collections have already been discovered in the area. Most of the works stem from the late Middle Ages, when Timbuktu was an important crossroads for caravans.
…
Archaeologists have shown that an incredible system of underground canals up to 20,000 kilometers (12,422 miles) long once existed at Wadi al-Hayat in Libya. Thanks to such hydraulic marvels, the desert blossomed and crops sprouted in the fields of the Tuareg.

Virgin Birth for Another Shark Species

Virgin shark birth in Virginia

The first time it happened, scientists thought it might be a fluke. A female hammerhead shark residing at a zoo in Omaha, Neb., had not been in contact with male sharks for at least three years and yet experienced a “virgin birth.” She delivered a single pup.

But it has happened again, according to today’s issue of the Journal of Fish Biology. This time, a blacktip shark… had spent nearly her entire eight years at either the Virginia Aquarium without any male companionship from her kind.

Science Postercasts

I wrote about SciVee, over a year ago, saying I thought they could become a valuable resource. It has been taking longer to really get going than I thought it would but this new feature, Postercasts, is great. I am glad to see SciVee living up to my high expectation. Keep up the great work SciVee. The experience can still use improvement but this is a great start.

They have provided a tutorial on: How to Synchronize my Poster to my Video. I hope some of our readers try this out.

Keeping Invassive Plants Out of Your Garden

Tending the Garden, Sparing the Ecosystem

The plants and animals that naturally exist in a place evolved together, adapted together and coexist for mutual benefit. Birds, insects and other animals help pollinate plants and distribute seeds. Plants provide food and shelter for the animals.

When you start adding exotic or nonnative species, or subtracting native species, you disrupt the balance. Native creatures may not be able to get nourishment from nonnative plants, and indigenous plants may not be able to compete with invasive alien plants.
…
The native plant society strongly recommends physical methods for getting rid of plants, as opposed to using herbicides. But where plant stands are large or hard to control by clipping or pulling, chemicals may well be the last resort.
