In a recently published study, Mayo Clinic researchers determined Math Learning Disorder (LD) is common among school-age children. Results show that boys are more likely to have Math LD than girls. The research also indicates that although a child can have a Math LD and a reading LD, a substantial percentage of children have Math LD alone. In fact, the cumulative incidence of Math LD through age 19 ranges from 6% to as high as 14%, depending on the Math LD definition. LD is used to describe the seemingly unexplained difficulty a person of at least average intelligence has in acquiring basic academic skills -- skills that are essential for success at school, work and for coping with life in general. The results appear in the September-October issue of Ambulatory Pediatrics.
"Our research on the incidence of Math LD indicates that Math LD is common, affecting many children at some time during their school years," says William Barbaresi, M.D., a Mayo Clinic developmental and behavioral pediatrician and an author of the study. "Our results support the notion that Math LD is an important problem that deserves attention from both researchers and educators."
Despite the recognized importance of mathematics, the majority of learning disability research has focused on reading. The prevalence of Math LD has been estimated at anywhere from one percent to six percent of school-age children. Research on Math LD has been hampered by differing definitions of Math LD and poorly defined criteria for identifying it. Most studies have looked at the prevalence of Math LD, ignoring changes in the group of students being studied, and making it difficult to determine the precise number of children affected by Math LD.

Nondestructive material testing (NDT) is a fast and effective way to analyze the quality of a product during the manufacturing process. Because defective materials can lead to malfunctioning finished products, NDT is an essential quality assurance measure, especially in the manufacture of safety-critical components such as automotive B-pillars. NDT examines the quality without damaging the component or modifying the surface of the material. At this year's Blechexpo trade fair in Stuttgart, Fraunhofer IZFP will have an exhibit that demonstrates the nondestructive testing of high-strength automotive body parts using 3MA. The measurement results are available in a matter of seconds.
To minimize vehicle weight and fuel consumption while providing the highest level of crash safety, automotive bodies are reinforced with elements made from...
The MICADO camera, a first light instrument for the European Extremely Large Telescope (E-ELT), has entered a new phase in the project: by agreeing to a Memorandum of Understanding, the partners in Germany, France, the Netherlands, Austria, and Italy, have all confirmed their participation. Following this milestone, the project's transition into its preliminary design phase was approved at a kick-off meeting held in Vienna. Two weeks earlier, on September 18, the consortium and the European Southern Observatory (ESO), which is building the telescope, have signed the corresponding collaboration agreement.
As the first dedicated camera for the E-ELT, MICADO will equip the giant telescope with a capability for diffraction-limited imaging at near-infrared...
Self-driving cars will be on our streets in the foreseeable future. In Graz, research is currently dedicated to an innovative driver assistance system that takes over control if there is a danger of collision. It was nature that inspired Dr Manfred Hartbauer from the Institute of Zoology at the University of Graz: in dangerous traffic situations, migratory locusts react around ten times faster than humans. Working together with an interdisciplinary team, Hartbauer is investigating an affordable collision detector that is equipped with artificial locust eyes and can recognise potential crashes in time, during both day and night.
