Whether bringing mental retardation, emotional and behavioral disorders, hearing impairment, exceptional abilities ("gifted") or other conditions, all are there to learn to the best of their abilities.
Despite a decade of public dissent and protests staged nationwide, it took a handful of senators to halt the war in Vietnam. A new book edited by distinguished professor of history Randall Woods examines the origins of their opposition. In the process, it suggests that challenging a president’s foreign policy can be both conscientious and patriotic — a fight for American values, rather than a betrayal of them.
No single acquisition of land did more to shape the United States than the Louisiana Purchase. But when Thomas Jefferson bought the land from France in 1803, the boundaries and features of the territory were largely unknown. The quest to map and measure that mysterious land began at the territory’s edge in a wilderness that would one day be known as the state of Arkansas.
A convergence of two great American pastimes — movies and baseball — "Reel Baseball" focuses on the ways that baseball has been used in movies as a form of cultural shorthand. As an example, author David Pincus, who teaches management in the Sam M. Walton College of Business, points to the movie "Pearl Harbor."
In the wake of the Iraqi conflict comes a timely translation: "Scattered Crumbs," a novel by Muhsin al-Ramli, translated from the Arabic by Yasmeen S. Hanoosh. Set in an Iraqi village during the Iran-Iraq war, the book tells the story of a peasant family in turmoil. The father, a fierce supporter of Saddam Hussein — here called "The Leader" — clashes with his artist son, who loves his homeland but finds himself unable to paint the leader’s portrait for his father’s wall. Hanoosh says the novel "evokes the processes of deterioration undergone both by the country and by the individual characters caught up in the maelstrom."
In "Promises Kept: A Memoir," by Sidney S. McMath, the former Arkansas governor discusses his early life in rural Arkansas, his military service, his political life and his career as a lawyer.

Most people don’t realize how much they rely on optical data networks in their daily lives until a cut in a cable or a faulty piece of equipment causes a split-second interruption in data flow. A massive power outage that crippled much of the northeastern United States in August demonstrated the incredible speed that optical data networks require to recover quickly from fault incidents and the serious consequences of a short interruption to critical systems.
You can find bottles on a grocery store shelf in the vitamins and minerals section with names like "Super Charge," "Over Drive" and "Optimum Omega." These products promise to "enhance natural killer cell activity," "support cardiovascular health" and "support healthy joint function." If these promises sound too good to be true, it’s because they are, says nutrition sciences professor Jerald Foote. He says that the majority of these products—called dietary supplements—never have been tested to support the claims they make, and they vary in quality, efficacy and safety.
Most Americans learned everything they know about courtroom law from Perry Mason and Jack McCoy, including the cornerstones of the American judicial system — "presumption of innocence" and "beyond a reasonable doubt." But law professor Steve Sheppard knows that the concept of reasonable doubt is changing, and that change may do away with the presumption of innocence.
