This article provides a summary of a landmark study on labor, in a large, multicenter modern cohort of women with singleton, vertex gestations. Emanuel Friedman published his original labor curve showing the expected progression of normal labor in 1955, and that for multiparous patients in 1956.2,3 He plotted the individual labor progression of 500 nulliparous laboring women from a single center to calculate the average progression of labor. In his cohort, 70% of whom were between 20 and 30 years old, many were Caucasian, and 55% of women were delivered via forceps. Dr. Friedman classically identified the second stage of labor starting at 4cm dilatation. Since the mid-20th century, many practice patterns have changed, and today’s population of women delivering in the United States is diverse and, on average, older and heavier than in 1955; therefore, use of the traditional labor curve has been questioned. The investigators in this study performed a secondary analysis of data from a multicenter cohort of 26,838 patients with singleton gestation, spontaneous labor, and normal outcomes. Using a sophisticated statistical approach Zhang et al. produced a modern labor curve.

This article reviews the history of empirical aesthetics since its foundation by Fechner in 1876 to Berlyne’s new empirical aesthetics in the 1970s. The authors explain why and how Fechner founded the field, and how Wundt and Müller’s students continued his work in the early 20th century. In the United States, empirical aesthetics flourished as part of American functional psychology at first, and later as part of behaviorists’ interest in reward value. The heyday of behaviorism was also a golden age for the development of all sorts of tests for artistic and aesthetic aptitudes. The authors end the article by covering the contributions of Gestalt psychology and Berlyne’s motivational theory to empirical aesthetics.

AbstractIn recent years, the migration rates from both China and India to the U.S. have accelerated. Since 2000 more than a third of foreign-born Chinese and 40% of foreign-born Indians have arrived in that country. This paper will document the evolving patterns of immigration from China and India to the U.S. by tracing the history of immigration and racial discrimination, the dramatic transitions that have occurred since the mid-20th century, and the current demographic and socioeconomic profiles of these two migrant groups.

From biblical times to the modern period, leprosy has been a disease associated with stigma. This mark of disgrace, physically present in the sufferers' sores and disfigured limbs, and embodied in the identity of a 'leper', has cast leprosy into the shadows of society. This paper draws on primary sources, written in Spanish, to reconstruct the social history of leprosy in Puerto Rico when the United States annexed this island in 1898. The public health policies that developed over the period of 1898 to the 1930s were unique to Puerto Rico because of the interplay between political events, scientific developments and popular concerns. Puerto Rico was influenced by the United States' priorities for public health, and the leprosy control policies that developed were superimposed on vestiges of the colonial Spanish public health system. During the United States' initial occupation, extreme segregation sacrificed the individual rights and liberties of these patients for the benefit of society. The lives of these leprosy sufferers were irrevocably changed as a result.

Long periods of one-party domination, increased average tenure in office for Representatives, and the institutionalization of patterns of succession to the Speakership, have all contributed to a tendency toward leadership stability in the 20th-century House of Representatives. The election of Sam Rayburn (D., Texas) and John McCormack (D., Mass.) to the offices of Speaker and Majority Leader in 1940, of Joseph Martin (R., Mass.) to the office of Minority Leader in 1939, and of Leslie Arends (R., Ill.) to the position of Republican Whip in 1943, mark the beginnings of the longest tenures in these four positions for any incumbents in the history of Congress. When changes in top leadership occur—as with the overthrow of Minority Leader Charles A. Halleck by Republican Representative Gerald R. Ford, Jr., in 1965, or the succession of Majority Leader McCormack to the office of the Speaker in 1962 following the death of Rayburn—the consequences are considerable. In the case of revolt, individual careers are made and broken. The organization and policy orientations of a congressional party may be extensively altered. While orderly succession has less dramatic impact, it too has a significant effect on “who gets what, when and how.” Some members move closer to the seats of power and others fall out of favor. Key committee assignments, and hence the development of entire legislative careers, are likely to ride or fall on the outcomes.

AbstractThis article reconstructs the 19th century history of events regarding a few female wax anatomical models made in Florence. More or less faithful copies of those housed in Florence's Museum of Physics and Natural History, these models were destined for display in temporary exhibitions. In their travels through Europe and the United States, they transformed the expression "Florentine Venus" into a sort of brand name used to label and offer respectability to pieces of widely varying quality.
