These areas of knowledge have converged into a modern theory of epidemiology that has been slow to penetrate into textbooks, particularly at the introductory level. Epidemiology: An Introduction closes the gap. It begins with a brief, lucid discussion of causal thinking and causal inference and then takes the reader through the elements of epidemiology, focusing on the measures of disease occurrence and causal effects. With these building blocks in place, the reader learns how to design, analyze and interpret problems that epidemiologists face, including confounding, the role of chance, and the exploration of interactions. All these topics are layered on the foundation of basic principles presented in simple language, with numerous examples and questions for further thought.

    Containing the black-and-white interiors and full-color covers of Primer #2 and Grendel #1-3 originally published by Comico, this handsome hardcover volume is an essential piece of comics history, presenting the earliest work of Matt Wagner, the legendary creator behind such acclaimed projects as Mage, Sandman Mystery Theatre and Batman: The Monster Men among many others.

    Out of this rare collaboration has come a dramatic work that is eminently readable and at the same time suitable for staging.

    The devices presented allow the speaker of a foreign language to demonstrate the level of his/her language more impressively.

    Now, in On the Air, Dunning has completely rethought this classic work, reorganizing the material and doubling its coverage, to provide a richer and more informative account of radio's golden age. Here are some 1,500 radio shows presented in alphabetical order. The great programs of the '30s, '40s, and '50s are all here--Amos 'n' Andy, Fibber McGee and Molly, The Lone Ranger, Major Bowes' Original Amateur Hour, and The March of Time, to name only a few. For each, Dunning provides a complete broadcast history, with the timeslot, the network, and the name of the show's advertisers. He also lists major cast members, announcers, producers, directors, writers, and sound effects people--even the show's theme song. There are also umbrella entries, such as News Broadcasts, which features an engaging essay on radio news, with capsule biographies of major broadcasters, such as Lowell Thomas and Edward R. Murrow. Equally important, Dunning provides a fascinating account of each program, taking us behind the scenes to capture the feel of the performance, such as the ghastly sounds of Lights Out (a horror drama where heads rolled and bones crunched), and providing engrossing biographies of the main people involved in the show. A wonderful read for everyone who loves old-time radio, On the Air is a must purchase for all radio hobbyists and anyone interested in 20th-century American history. It is an essential reference work for libraries and radio stations.
