This essay synthesizes the history of the birth control movement in the US and describes changes in sexual behavior, social values, and public policy in order to provide a context for the changes in human reproductive public policy. After an introduction, the essay outlines the history of contraception from the early nineteenth to the early twentieth centuries. Part 3 covers the period of World War I to the Depression when civil libertarians and eugenicists began to question the suppression of contraception and Margaret Sanger organized her clinics. The fourth part of the essay carries the history forward to the end of World War II, a period in which Dr. Clarence J. Gamble began to expose the marketing of defective contraceptive methods and to illustrate the willingness of poor women to accept contraceptives. The social changes which began in the 1950s are the subject of the fifth section of the essay. During this period, Roman Catholic opposition to contraception lessened, and social scientists began to focus world attention on overpopulation. Frank Notestein was appointed the first head of the Office of Population Research at Princeton, and John D. Rockefeller III founded the Population Council which conducted research into the IUD and began to attempt to influence population growth in nonindustrialized countries. This period also saw the development of the oral contraceptive. The changes of this era were institutionalized in 1967 when the federal government took a positive stance towards family planning in its Social Security Amendments. The decade of the 1970s is the subject of the last part of this essay. This period saw the Supreme Court assign a constitutionally protected right to abortion and Congress pass the Helms Amendment which denied the use of foreign aid funds for abortions. Challenges to the right to individual birth control practice continued during this period, and debate centered around the specter of overpopulation, the threat of adolescent pregnancy, and perceptions of "family values."  相似文献

This paper presents the results of in situ monitoring of waterlogged burial contexts in southwest Scotland. The sites investigated are Iron Age crannogs (lake dwellings) which have a proven waterlogged archaeological component, and which are being assessed as part of a national program of study by the Scottish Wetland Archaeology Programme (SWAP) team. A monthly monitoring program commenced in July of 2004. To date, monitoring of water levels, pH, and redox potential, has been undertaken for a period of 17 months in order to encompass any seasonal variability at the sites studied. The results have proven robust in that an ‘ideal’ site for in situ preservation has been identified from the five sites investigated, and the monitoring has highlighted external variables and seasonal impacts that have the potential to influence the long-term in situ preservation at the remaining sites studied. In general, these results have expanded upon our knowledge of the potential for the preservation of existing archaeological remains within such contexts. This study represents the first stage of monitoring aimed at developing a holistic understanding of in situ conditions at the crannog sites studied in southwest Scotland.  相似文献

On the Rank-Size Distribution for Human Settlements   总被引:9,自引:0,他引:9  
An explanation for the rank-size distribution for human settlements based on simple stochastic models of settlement formation and growth is presented. Not only does the analysis of the model explain the rank-size phenomenon in the upper tail, it also predicts a reverse rank-size phenomenon in the lower tail. Furthermore it yields a parametric form (the double Pareto-lognormal distribution) for the complete distribution of settlement sizes. Settlement-size data for four regions (two in Spain and two in the U.S.) are used as examples. For these regions the lower tail rank-size property is seen to hold and the double Pareto-lognormal distribution shown to provide an excellent fit, lending support to the model and to the explanation for the rank-size law.  相似文献

In 1994 investigations comprising geophysical and earthwork surveys, together with evaluation excavations were carried out at Hylton Castle, Sunderland. The results confirmed the former presence of buildings east of the gatehouse tower, and contemporary with it. Some evidence for a hitherto unknown sixteenth- or seventeenth- century successor to the castle was discovered on an artificial terrace overlooking the earthworks of an ornamental garden with associated water features.  相似文献

At Rockley, Yorkshire (SE338021) there survives the stone stack of a blast furnace which archive sources suggest was built in about 1700 and was used with charcoal until at least 1741. Antiquarian suggestions of a later period of operation using coke have received archaeological support in excavations carried out between 1978 and 1982. These established the layout of the blowing and casting houses, as well as the position of a head race, and of a water wheel of which only fragments survived. Of particular significance was a stone-lined casting pit, inserted into the floor of the casting house. The results of this excavation provide new impetus for research on the adaptation of charcoal blast furnaces for the use of coke.  相似文献
