Black American women are shrinking in height at a faster rate than other groups, a phenomenon that has consequences for the physical health and economic well-being of black females. Relative to the cohort born from 1955 to 1974, the most recent cohort (1970–1986) of black American women and girls have lost more than half an inch (approximately 0.56) in height. Adult height is a measure of net nutrition acquired during childhood and adolescence and is correlated with a wide variety of economic and health outcomes. Simultaneously, the body mass index (BMI) among blacks has also increased at a faster rate than whites in both the periods of 1988–1994 (1.06 kg/m2) and 1999–2002. Black women and girls, in particular, experienced the greatest increase in BMI since the 1990s. Evidence that black American women are shrinking and BMI is growing highlights the need to examine the nutritional intake of black girls during childhood and adolescence; early nutritional deficiencies have persistent impact over their life course. In this policy brief, we consider several public health policy interventions that affect black girls’ nutritional intake across the life course, particularly during childhood and adolescence. 相似文献

The paper examines methodological and subject aspects of some problem questions that arise in organizing and technologization a long-term forecast procedure. It looks at the basic elements of the methodology and technique of a long-term forecast performed during the development of the Concept for Long-term Socioeconomic Development of the Russian Federation. Key conditions for technology application in the framework of two possible scenarios of Russian economic growth, primary-and-energy and innovation-active, are analyzed. 相似文献

The authors examine current textbook representations of Coase's analysis of negative externalities [Coase, 1960]. Standard
treatments identify Coase's ideas with Stigler's Coase Theorem: a zero transaction cost world in which efficient solutions
emerge automatically, regardless of legal rules and the initial allocation of rights. Yet Coase's seminal paper breaks from
this mode of analysis. The authors use this intellectual history to distinguish two approaches to negative externalities:
blackboard (Pigou, Stigler, Samuelson) and Coasean. They survey 45 microeconomics textbooks and find that 80 percent misrepresent
Coase's arguments. They argue that a Coasean approach increases students' critical thinking skills by challenging them to
move beyond simple laissez faire or interventionist solutions. 相似文献
