Decades ago, when the Outcome Based Education movement was trying to take hold, educators who were already overburdened did not want to be saddles with managing social and emotional development of diverse classrooms and the competing goals of parents.
Parents agreed that turning over the social development of children to school districts was a bad idea but a new paper says that classroom programs designed to improve elementary school students' social and emotional skills also increase reading and math achievement, even if academic improvement is not a direct goal of the skills building. The benefit holds true for students across a range of socio-economic backgrounds, they say.
According to the results of a recent study, soil color changes in the atmosphere basically through the oxidation of chemical substances in the soil. The fundamental mechanism is the remodeling effect of micro-structures because of motion effects and chemical reactions of the water–soil–electrolyte–atmosphere system leading to the coupling and transforming of soil particles. The above provides a theoretical foundation for the assessment and forecast of the stability of the geotechnical environment.
COLUMBIA, S.C. — Dispersants are often used in oil spill responses because they may mitigate the environmental impacts of the spill by moving the oil from the water surface into the water column enhancing its biodegradation. While this process helps reduce the likelihood of oil exposure to marine wildlife such as seabirds and marine mammals, aquatic toxicity on marine communities from the dispersant and the chemically dispersed oil needs to be considered more carefully.
Collectors,museums and art dealers face a lot of problems determining origin, authenticity and discovery of forgery of artwork. Experts are easily fooled - but science, not so much.
They get help through the application of modern, non-destructive, "hi-tech" techniques. Spectroscopy is a technique that has been useful in the fight against art fraud because it can determine chemical composition of pigments and binders, which is essential information in the hands of an art specialist in revealing fakes. As described in a recent paper, "…according to the FBI, the value of art fraud, forgery and theft is up to $6 billion per year, which makes it the third most lucrative crime in the world after drug trafficking and the illegal weapons trade."
If you feel ill, chances are you go to the Internet before you see a doctor. Most Americans have seen dramatic rises in health care premiums thanks to new government mandates and penalties, but the cultural groundwork to visit doctors less was laid a decade ago in most developed nations.
Professor Sue Ziebland, Director of the Health Experiences Research Grou at the University of Oxford, share findings with health practitioners and researchers at the South West Society for Academic Primary Care (SW SAPC) meeting at the University of Bristol on Thursday.
A theoretical study led by the University of Exeter has shed new light on the conditions that lead to the evolution of spite or altruism in structured populations.
Understanding the way in which social behaviours such as altruism – when animals benefit others at their own expense – develop is a long-standing problem that has generated thousands of articles and heated debates.
Dr Florence Débarre of Biosciences at the University of Exeter led a study, published today in Nature Communications, which presents a comprehensive framework that applies to a large class of population structures and identifies the crucial elements which support the evolution of social behaviour.
The uplifting effects of energy drinks are well advertised, but a new report finds consumption among teenagers may be linked with poor mental health and substance use.
Researchers are calling for limits on teen's access to the drinks and reduction in the amount of the caffeine in each can.
The paper by researchers at the University of Waterloo and Dalhousie University, published in Preventive Medicine, found that high school students prone to depression as well as those who are smoke marijuana or drink alcohol are more likely to consume energy drinks than their peers.
Millions of high school and college algebra students are united in a shared agony over solving for x and y, and for those to whom the answers don't come easily, it gets worse: Most preschoolers and kindergarteners can do some algebra before even entering a math class.
In a recently published study in the journal Developmental Science, lead author and post-doctoral fellow Melissa Kibbe and Lisa Feigenson, associate professor of psychological and brain sciences at Johns Hopkins University's Krieger School of Arts and Sciences, find that most preschoolers and kindergarteners, or children between 4 and 6, can do basic algebra naturally.
Light can trigger coordinated, wavelike motions of atoms in atom-thin layers of crystal, scientists have shown. The waves, called phonon polaritons, are far shorter than light waves and can be "tuned" to particular frequencies and amplitudes by varying the number of layers of crystal, they report in the early online edition of Science March 7.
These properties - observed in this class of material for the first time - open the possibility of using polaritons to convey information in tight spaces, create images at far finer resolution than is possible with light, and manage the flow of heat in nanoscale devices.
The Earth's magnetic field, or magnetosphere, stretches from the planet's core out into space, where it meets the solar wind, a stream of charged particles emitted by the sun. For the most part, the magnetosphere acts as a shield to protect the Earth from this high-energy solar activity.
But when this field comes into contact with the sun's magnetic field — a process called "magnetic reconnection" — powerful electrical currents from the sun can stream into Earth's atmosphere, whipping up geomagnetic storms and space weather phenomena that can affect high-altitude aircraft, as well as astronauts on the International Space Station.
In the tropical highlands of South America and East Africa, cool temperatures have historically kept mosquito-borne diseases, such as malaria, at bay. New research by Howard Hughes Medical Institute (HHMI) scientists shows that as annual temperatures rise in these areas, malaria can spread to populations in higher elevations that had historically not been at as much risk of being infected by malaria parasites.
A team of researchers led by Mayland Chang and Shahriar Mobashery have discovered a new class of antibiotics to fight bacteria such as methicillin-resistant Staphylococcus aureus (MRSA) and other drug-resistant bacteria that threaten public health.
Changes to two previously unstudied genes are the centerpiece of a new theory regarding the cause and development of endometriosis, a chronic and painful disease affecting 1 in 10 women.
The discovery by Northwestern Medicine scientists suggests epigenetic modification, a process that enhances or disrupts how DNA is read, is an integral component of the disease and its progression. Matthew Dyson, research assistant professor of obstetrics and gynecology at Northwestern University Feinberg School of Medicine and and Serdar Bulun, MD, chair of obstetrics and gynecology at Feinberg and Northwestern Memorial Hospital, also identified a novel role for a family of key gene regulators in the uterus.
We often think of playing fair as an altruistic behavior. We're sacrificing our own potential gain to give others what they deserve. What could be more selfless than that? But new research from Northeastern University assistant professor of philosophy Rory Smead suggests another, darker origin behind the kindly act of fairness.
ITHACA, N.Y. – To buy, or not to buy? That is the question for the more than 5 million annual visitors to New York's wineries. Cornell University researchers found that customer service is the most important factor in boosting tasting room sales, but sensory descriptions of what flavors consumers might detect were a turn-off.
The findings stem from two studies on how the tasting room experience affects customer purchases and what wineries can do to create satisfied sippers, published in the current issue of the International Journal of Wine Business Research.
I’ll borrow an analogy for a simplified description of how public key encryption works from Simon Singh. Imagine a sturdy metal box that can be locked shut with a padlock.-->
EVANSTON, Ill. --- There is a lot that 19-month-old children can't do: They can't tie their shoes or get their mittens on the correct hands. But they can use words they do know to learn new ones.
New research from Northwestern University demonstrates that even before infants begin to talk in sentences, they are paying careful attention to the way a new word is used in conversations, and they learn new words from this information in sentences.
People with type 2 diabetes have epigenetic changes on their DNA that healthy individuals do not have. This has been shown in a major study by researchers at Lund University. The researchers also found epigenetic changes in a large number of genes that contribute to reduced insulin production.
"This shows that the risk of developing type 2 diabetes is not only genetic, but also epigenetic", said Charlotte Ling, who led the study.
Researchers at Brigham and Women's Hospital (BWH) in Boston, Massachusetts, in collaboration with investigators at the Maastricht University Medical Centre and Maastricht University School of Public Health in the Netherlands and The University of Edinburgh in the United Kingdom, have published findings strongly suggesting that preterm birth (prior to 37 weeks gestation) increases the risk of asthma and wheezing disorders during childhood and that the risk of developing these conditions increases as the degree of prematurity increases.
