This article examines the development of the incubator for premature infants in fin-de-siècle France. During a period of widespread anxiety in France regarding infant mortality and its implications for population growth, physicians in Paris developed and widely promoted the lifesaving technology. This article explores the ways in which the incubator reflected new scientific and symbolic approaches to creating hygienic spaces as well as how it reflected new scientific and symbolic approaches to the traditionally feminine project of infant care. By creating such an isolating and protective milieu around premature infants—an entirely new population of patients—the incubator, I argue, heralded a renegotiation of the boundary between motherhood and medical authority.  相似文献

早起的人们     
清晨的阳光倾洒在香港的一条横街上。那时的香港是英属殖民地,依着起伏的地势建了不少这样的“台阶街道”。1934年11月号的《国家地理》对这张照片的解说是“只有步行和坐轿的才能在这街上走动。大约有36万中国人在香港生活、做生意。”图说继续写道.“还有同等数量的居民住在海港对岸的九龙或船上。”今天已经有约700万人定居香港。  相似文献

This article aims at illustrating the historical circumstances that led Julius Bernstein in 1902 to formulate a membrane theory on resting current in muscle and nerve fibers. It was a truly paradigm shift in research into bioelectrical phenomena, if qualified by the observation that, besides Bernstein, many other electrophysiologists between 1890 and 1902 borrowed ideas from the recent ionistic approach in the physical-chemistry domain. But Bernstein's subjective perception of that paradigm shift was that it constituted a mere reinterpretation of the so-called preexistence theory advanced by his teacher Emil du Bois-Reymond in the first half of the nineteenth century.  相似文献

This study outlines a long history of divorce in Sweden, recognizing the importance of considering both economic and cultural factors in the analysis of marital dissolution. Following Ansley Coale, the authors examine how a framework of multiple theoretical constructs, in interaction, can be applied to the development toward mass divorce. Applying a long historical perspective, the authors argue that an analysis of gendered aspects of the interaction between culture and economics is crucial for the understanding of the rise of mass divorce. The empirical analysis finds support for a marked decrease in legal and cultural obstacles to divorce already during the first decades of the twentieth century. However, economic structures remained a severe obstacle that prohibited significant increases in divorce rate prior to World War II. It was only during the 1940s and 1960s, when cultural change was complemented by marked decreases in economic interdependence between spouses, that the divorce rate exhibited significant increases. The authors find that there are advantages to looking at the development of divorce as a history in which multiple empirical factors are examined in conjunction, recognizing that these factors played different roles during different time periods.  相似文献

Beginning in the 1850s, the struggling farming family of Elijah Dunham (1810-1893) and Anna Maria Briggs (1813-1899) ceased to function as a single economic and social unit. The children left the family home to establish lives and families of their own in various parts of Canada and the United States. As the family dispersed, however; they continued to maintain contact through letters. In the letters, the family shared news, sought advice, received comfort, and, at times, vented their frustrations and exposed internal family tensions. The letters provided a means of requesting and extending financial assistance, especially as it came to maintaining the elderly parents back in Ontario. Although the family would never again inhabit the same geographic location, they continued to function as a kinship network even though separated by time and space.  相似文献

On July 2, 1881, Charles Julius Guiteau shot President James Abram Garfield in the right flank. The President died because of infection produced by the unsterile fingers and probes repeatedly inserted into the wound. The major complaint of the wounded President was intractable pain in his legs and feet. This symptom failed to alert the doctors to the possibility of vertebral and spinal cord injury. Garfield died with sepsis after 80 days of intense national concern, and for the patient there was psychological, physical, and nutritional deprivation. His autopsy revealed the bullet was not in the pelvis as his doctors had expected, but adjacent to the first lumbar vertebra it had shattered. The trial and execution of Guiteau split the medical community into those that considered him insane and those who felt execution was justified. Guiteau was delusional and his brain revealed chronic inflammation and histological features suggestive of syphilis. At the time, and since, the propriety of the execution has been questioned.  相似文献
