Before 1960, little empirical research was done on forecasting methods. Since then, the literature has grown rapidly, especially in the area of judgmental forecasting. This research supports and adds to the forecasting guidelines proposed before 1960, such as the value of combining forecasts. New findings have led to significant gains in our ability to forecast and to help people to use forecas...

We examine the joint distribution of levels of income per capita, life expectancy, and years of schooling across countries in 1960 and in 2000. In 1960 countries were clustered in two groups; a rich, highly educated, high longevity "developed" group and a poor, less educated, high mortality, "underdeveloped" group. By 2000 however we see the emergence of three groups; one underdeveloped group r...

The United States has made progress in decreasing the black-white gap in civil rights, housing, education, and income since 1960, but health inequalities persist. We examined trends in black-white standardized mortality ratios (SMRs) for each age-sex group from 1960 to 2000. The black-white gap measured by SMR changed very little between 1960 and 2000 and actually worsened for infants and for A...

We present CCD photometry and proper motion studies of the two open star clusters NGC 1960 (M 36) and NGC 2194. Fitting isochrones to the colour magnitude diagrams, for NGC 1960 we found an age of t = 16 Myr and a distance of roughly d = 1300 pc and for NGC 2194 t = 550 Myr and d = 2900 pc, respectively. We combined membership determination by proper motions and statistical field star subtracti...

Two chigger mite species, Ericotrombidium tarentolae (Vercammen-Grandjean and Langston, 1976) Neotrombicula orycti Taufflieb, 1960, have been recorded outside their type localities on two species of geckos from the genus Quedenfeldtia Boettger for first time. One new subjective synonym has established base examination specimens additional materials — 1960 (syn.: lemni n. syn.).

The possibility of obtaining intervillous blood from pregnant women has made it feasible to study the placental exchange of various substances. Those which are perhaps most vital, i.e. oxygen and carbon dioxide, have already been studied to some extent (Prystowsky, 1957, 1958, 1959, 1960; Prystowsky, Hellegers and Bruns, 1960; Walker, 1959; Sjostedt, Rooth and Caligara, 1960; Rooth, Sjostedt an...
