Abstract. The United States government has operated Dobson ozone spectrophotometers at various sites, starting during the International Geophysical Year (1 July 1957 to 31 December 1958). A network of stations for long-term monitoring of the total column content (thickness of the ozone layer) of the atmosphere was established in the early 1960s and eventually grew to 16 stations, 14 of which are still operational and submit data to the United States of America's National Oceanic and Atmospheric Administration (NOAA). Seven of these sites are also part of the Network for the Detection of Atmospheric Composition Change (NDACC), an organization that maintains its own data archive. Due to recent changes in data processing software the entire dataset was re-evaluated for possible changes. To evaluate and minimize potential changes caused by the new processing software, the reprocessed data record was compared to the original data record archived in the World Ozone and UV Data Center (WOUDC) in Toronto, Canada. The history of the observations at the individual stations, the instruments used for the NOAA network monitoring at the station, the method for reducing zenith-sky observations to total ozone, and calibration procedures were re-evaluated using data quality control tools built into the new software. At the completion of the evaluation, the new datasets are to be published as an update to the WOUDC and NDACC archives, and the entire dataset is to be made available to the scientific community. The procedure for reprocessing Dobson data and the results of the reanalysis on the archived record are presented in this paper. A summary of historical changes to 14 station records is also provided.

Abstract. The United States government has operated Dobson Ozone Spectrophotometers at various sites, starting during the International Geophysical Year (July 1, 1957 to December 31, 1958). A network of stations for longterm monitoring of the total column content (thickness of the ozone layer) of the atmosphere was established in the early 1960s, and eventually grew to sixteen stations, fourteen of which are still operational and submit data to the United States of America’s National Oceanic and Atmospheric Administration (NOAA). Seven of these sites are also part of the Network for the Detection of Atmospheric Composition Change (NDACC), an organization that maintains its own data archive. Due to recent changes in data processing software the entire data set was reevaluated for possible changes. To evaluate and minimize potential changes caused by the new processing software, the reprocessed data record was compared to the original data record archived in the World Ozone and UV Data Center (WOUDC) in Toronto, Canada. The history of the observations at the individual stations, the instruments used for the NOAA network monitoring at the station, the method for reducing zenith sky observations to total ozone, and calibration procedures were re-evaluated using data quality control tools built into the new software. At the completion of the evaluation, the new data sets are to be published as an update to the WOUDC and NDACC archives, and the entire data set is to be made available to the scientific community. The procedure for reprocessing Dobson data and the results of the re-analysis on the archived record is presented in this paper. A summary of historical changes to fourteen station records is also provided.

AbstractThis study employs the Solomon Four-Group Design to measure student knowledge of the United States government and student knowledge of current events at the beginning of a U.S. government course and at the end. In both areas, knowledge improves significantly. Regarding knowledge of the U.S. government, both males and females improve at similar rates, those with higher and lower GPAs improve at similar rates, and political science majors improve at similar rates to non-majors. Regarding current events, males and females improve at similar rates. However, those with higher GPAs and political science majors improve more than others.

The Security Council discussed this question at its 1022nd–1025th meetings, on October 23–25, 1962. It had before it a letter dated October 22, 1962, from the permanent representative of the United States, in which it was stated that the establishment of missile bases in Cuba constituted a grave threat to the peace and security of the world; a letter of the same date from the permanent representative of Cuba, claiming that the United States naval blockade of Cuba constituted an act of war; and a letter also dated October 22 from the deputy permanent representative of the Soviet Union, emphasizing that Soviet assistance to Cuba was exclusively designed to improve Cuba's defensive capacity and that the United States government had committed a provocative act and an unprecedented violation of international law in its blockade.

Soviet Russia

In March 1921 Lenin predicted, “If there is a harvest, everybody will hunger a little and the government will be saved. Otherwise, since we cannot take anything from people who do not have the means to satisfy their own hunger, the government will perish.“ By early summer, Russia was in the grip of one of the worst famines in its history. Lenin's gloomy forecast, however, was never put to the test. At almost the last moment, substantial help in the form of food, clothing, and medical supplies arrived from a most unexpected source —U.S. Secretary of Commerce Herbert Hoover.Hoover undertook the relief of Soviet Russia not as an official representative of the United States government but as the head of a private agency —the American Relief Administration (A.R.A.).
