In the decade of the 1970s, item response theory became the dominant topic for study by measurement specialists. But, the genesis of item response theory (IRT) can be traced back to the mid-thirties and early forties. In fact, the term "Item Characteristic Curve," which is one of the main IRT concepts, can be attributed to Ledyard Tucker in 1946. Despite these early research efforts, interest in item response theory lay dormant until the late 1960s and took a backseat to the emerging development of strong true score theory. While true score theory developed rapidly and drew the attention of leading psychometricians, the problems and weaknesses inherent in its formulation began to raise concerns. Such problems as the lack of invariance of item parameters across examinee groups, and the inadequacy of classical test procedures to detect item bias or to provide a sound basis for measurement in "tailored testing," gave rise to a resurgence of interest in item response theory. Impetus for the development of item response theory as we now know it was provided by Frederic M. Lord through his pioneering works (Lord, 1952; 1953a, 1953b). The progress in the fifties was painstakingly slow due to the mathematical complexity of the topic and the nonexistence of computer programs.
By using familiar concepts from classical measurement methods and basic statistics, this book introduces the basics of item response theory (IRT) and explains the application of IRT methods to problems in test construction, identification of potentially biased test items, test equating and computerized-adaptive testing. The book also includes a thorough discussion of alternative procedures for estimating IRT parameters and concludes with an exploration of new directions in IRT research and development.
In 1880, ancient-growth forest still covered two-thirds of West Virginia, but by the 1920s lumbermen had denuded the entire region. Ronald Lewis explores the transformation in these mountain counties precipitated by deforestation. As the only state that lies entirely within the Appalachian region, West Virginia provides an ideal site for studying the broader social impact of deforestation in Appalachia, the South, and the eastern United States. Most of West Virginia was still dominated by a backcountry economy when the industrial transition began. In short order, however, railroads linked remote mountain settlements directly to national markets, hauling away forest products and returning with manufactured goods and modern ideas. Workers from the countryside and abroad swelled new mill towns, and merchants ventured into the mountains to fulfill the needs of the growing population. To protect their massive investments, capitalists increasingly extended control over the state's legal and political systems. Eventually, though, even ardent supporters of industrialization had reason to contemplate the consequences of unregulated exploitation. Once the timber was gone, the mills closed and the railroads pulled up their tracks, leaving behind an environmental disaster and a new class of marginalized rural poor to confront the worst depression in American history.

Perhaps the most spectacular reaction to court-ordered busing in the 1970s occurred in Boston, where there was intense and protracted protest. Ron Formisano explores the sources of white opposition to school desegregation. Racism was a key factor, Formisano argues, but racial prejudice alone cannot explain the movement. Class resentment, ethnic rivalries, and the defense of neighborhood turf all played powerful roles in the protest. In a new epilogue, Formisano brings the story up to the present day, describing the end of desegregation orders in Boston and other cities. He also examines the nationwide trend toward the resegregation of schools, which he explains is the result of Supreme Court decisions, attacks on affirmative action, white flight, and other factors. He closes with a brief look at the few school districts that have attempted to base school assignment policies on class or economic status.

Exceptional Children: Integrating Research and Teaching provides a com prehensive introduction to the constantly changing area of special educa tion. The book is research-based, and its title reflects our opinion regarding the important link between research and classroom practice. There is one feature of Exceptional Children: Integrating Research and Teaching that warrants attention and perhaps justification; it was written specifically to address the graduate student or sophisticated undergraduate student mar ket. As such, the book is written at a higher level and with a greater concept density than typical introductory special education texts. We feel that this type of book is very much needed and will be received favorably by the special education community. There are also several unique features of Exceptional Children: Integrat ing Research and Teaching that we feel will be quite valuable. First, we have emphasized the area of teaching practices and not simply included basic facts about definitions, characteristics, and causes. Although some intro ductory texts include information about teaching considerations, that area is not discussed as in depth as it is in our text. We feel that it is important that readers not only understand the educational needs of exceptional chil dren, but also can identify the best educational practices to meet those needs.
The War of 1812 is typically noted for a handful of events: the burning of the White House, the rise of the Star Spangled Banner, and the battle of New Orleans. But in fact the greatest consequence of that distant conflict was the birth of the U.S. Navy. During the War of 1812, America’s tiny fleet took on the mightiest naval power on earth, besting the British in a string of victories that stunned both nations. In his new book, Ships of Oak and Guns of Iron: The War of 1812 and the Birth of the American Navy, author Dr. Ronald Utt not only sheds new light on the naval battles of the War of 1812 and how they gave birth to our nation’s great navy, but tells the story of the War of 1812 through the portraits of famous American war heroes. From the cunning Stephen Decatur to the fierce David Porter, Ships of Oak and Guns of Iron relates how thousands of American men and boys gave better than they got against the British Navy. The great age of fighting sail is as rich in heroic drama as any epoch. Dr. Utt’s Ships of Oak and Guns of Iron retrieves the American chapter of that epoch from unjustified obscurity, and offers readers an intriguing chronicle of the War of 1812 as well as a unique perspective on the birth of the U.S. Navy.

Selling Folk Music: An Illustrated History highlights commercial sources that reveal how folk music has been packaged and sold to a broad, shifting audience in the United States. Folk music has a varied and complex scope and lineage, including the blues, minstrel tunes, Victorian parlor songs, spirituals and gospel tunes, country and western songs, sea shanties, labor and political songs, calypsos, pop folk, folk-rock, ethnic, bluegrass, and more. The genre is of major importance in the broader spectrum of American music, and it is easy to understand why folk music has been marketed as America's music. Selling Folk Music presents the public face of folk music in the United States via its commercial promotion and presentation throughout the twentieth century. Included are concert flyers; sheet music; book, songbook, magazine, and album covers; concert posters and flyers; and movie lobby cards and posters, all in their original colors. The 1964 hootenanny craze, for example, spawned such items as a candy bar, pinball machine, bath powder, paper dolls, Halloween costumes, and beach towels. The almost five hundred images in Selling Folk Music present a new way to catalog the history of folk music while highlighting the transformative nature of the genre. Following the detailed introduction on the history of folk music, illustrations from commercial products make up the bulk of the work, presenting a colorful, complex history.
