Weight Gain During Pregnancy


Book Description

As women of childbearing age have become heavier, the trade-off between maternal and child health created by variation in gestational weight gain has become more difficult to reconcile. Weight Gain During Pregnancy responds to the need for a reexamination of the 1990 Institute of Medicine guidelines for weight gain during pregnancy. It builds on the conceptual framework that underscored the 1990 weight gain guidelines and addresses the need to update them through a comprehensive review of the literature and independent analyses of existing databases. The book explores relationships between weight gain during pregnancy and a variety of factors (e.g., the mother's weight and height before pregnancy) and places this in the context of the health of the infant and the mother, presenting specific, updated target ranges for weight gain during pregnancy and guidelines for proper measurement. New features of this book include a specific range of recommended gain for obese women. Weight Gain During Pregnancy is intended to assist practitioners who care for women of childbearing age, policy makers, educators, researchers, and the pregnant women themselves to understand the role of gestational weight gain and to provide them with the tools needed to promote optimal pregnancy outcomes.







Preparing for Future Products of Biotechnology


Book Description

Between 1973 and 2016, the ways to manipulate DNA to endow new characteristics in an organism (that is, biotechnology) have advanced, enabling the development of products that were not previously possible. What will the likely future products of biotechnology be over the next 5â€"10 years? What scientific capabilities, tools, and/or expertise may be needed by the regulatory agencies to ensure they make efficient and sound evaluations of the likely future products of biotechnology? Preparing for Future Products of Biotechnology analyzes the future landscape of biotechnology products and seeks to inform forthcoming policy making. This report identifies potential new risks and frameworks for risk assessment and areas in which the risks or lack of risks relating to the products of biotechnology are well understood.




Fighting for the Speakership


Book Description

The Speaker of the House of Representatives is the most powerful partisan figure in the contemporary U.S. Congress. How this came to be, and how the majority party in the House has made control of the speakership a routine matter, is far from straightforward. Fighting for the Speakership provides a comprehensive history of how Speakers have been elected in the U.S. House since 1789, arguing that the organizational politics of these elections were critical to the construction of mass political parties in America and laid the groundwork for the role they play in setting the agenda of Congress today. Jeffery Jenkins and Charles Stewart show how the speakership began as a relatively weak office, and how votes for Speaker prior to the Civil War often favored regional interests over party loyalty. While struggle, contention, and deadlock over House organization were common in the antebellum era, such instability vanished with the outbreak of war, as the majority party became an "organizational cartel" capable of controlling with certainty the selection of the Speaker and other key House officers. This organizational cartel has survived Gilded Age partisan strife, Progressive Era challenge, and conservative coalition politics to guide speakership elections through the present day. Fighting for the Speakership reveals how struggles over House organization prior to the Civil War were among the most consequential turning points in American political history.
