Potential impact on birth rates of reforms in laws governing contraceptive marketing

This article attempts to estimate the potential impact on birth rates of relaxing various legal restrictions on the marketing of contraceptives and to identify countries offering particular potential for such policies. The approach is through a quasi-experimental cross-sectional analysis of various configurations of laws in 82 countries. Results indicate that relaxation of a complex of interrelated restrictions offers the potential to lower birth rates and hence population growth by a full percentage point. The estimates are made in context of an analysis of covariance in which other key determinants of birth rates (measures of economic, demographic and health status) are also considered. While the cross-sectional design does not allow assessment of time frame for the impact of such changes, some guidance is available from the experience of two countries.     

The processing of the results of chemical toxicological research using microcalculators

Three programs for computer microcalculators "Elektronika MK-52", "Elektronika MK-54", "Elektronika MK-56", "Elektronika MK-61", and "Elektronika BZ-34" were studied. The first program allows one to calculate degree of substance extraction and rate of its distribution between two liquid unmixing phases; the second program is used for calculations on substance distribution in the organs of laboratory animals; the third program helps to calculate specific and molar rates of light absorption. Programs may be used in mathematical processing of results obtained in scientific research.     

President Roosevelt,Admiral Stark,and the Unsent Warning to Pearl Harbor: A Research Note

Admiral Harold R. Stark (1880–1972) was appointed Chief of Naval Operations in August 1939 and served in that role until removed in March 1942. It was on his watch that the Japanese raided Pearl Harbor on 7 December 1941. Nowadays the prevailing view of Stark seems to be largely shaped by the official verdict of the Secretary of the Navy, James V. Forrestal, namely that “Admiral Harold R. Stark, USN (Retired), shall not hold any position in the United States Navy which requires the exercise of superior judgment”. Our very different view is that Stark was a patriot who willingly sacrificed his reputation to preserve that of President Franklin D. Roosevelt and to enable him, as the one person capable of leading the Allies to victory in war against Nazi Germany, to assume his proper mantle.
