Abortion Practice is the only single-author medical textbook concerning abortion. It begins with a comprehensive view in its first chapter of The Epidemiologic Foundations of Abortion Practice. This chapter is a unique in the medical literature in presenting a public health view of pregnancy and abortion. Pregnancy is seen as a biocultural adaptation to the survival needs of the human species, and the management of pregnancy as a biocultural phenomenon that is determined by human culture. In many cultures, pregnancy is defined as a life-threatening illness, but in western culture, pregnancy is defined as normal. This reflects the role of women in western society and it affects the kinds of medical and surgical management of pregnancy that are available. Abortion alters the mortality statistics - the risk of death - for women who are pregnant. The remainder of the book provides a framework for modern abortion practice including evaluation of the patient, operative procedures and techniques, postoperative procedures, management of complications, diagnostic evaluation of pregnancy duration and fetal age, long-term risks of abortion, and program evaluation.

The April 20th 2010 explosion of the Deepwater Horizon offshore drilling rig led to the largest oil spill in U.S. waters. Federal government officials estimated that the deepwater well ultimately released over 200 million gallons of crude oil. Although decreasing amounts of oil were observed on the ocean surface following the well's containment on July 15th 2010, oil spill response officials and researchers have found oil in other places. This new book examines the fate of the oil from the Deepwater Horizon spill. Direct observation and measurement of the fate of the vast majority of the estimated 200 million gallons of oil presents a considerable challenge.
