The history of the synapse concept is traced from its inception in the 1890s to the present day. Three major periods are highlighted: the 1890s, the mid-twentieth century and modern times. The dependence of progress on the development of techniques is emphasised. The significance of the external context, the metaphors and general theory within which work proceeds, is also stressed. The development of the synapse concept can be seen to depend on a complex interplay between these internal and external factors. The reticularist/neuronist controversy provides a continuing leitmotiv.  相似文献

路易十五时代的法国启蒙思想家们掀起了持续不断的争取报刊自由的运动.英国诗人弥尔顿发表于1644年主张报刊自由的辩护词,以及1776年弗吉尼亚宣告报刊自由的行动,都激励了法国报刊自由的拥护者.1788年7月5目的法兰西王国行政法院决议给予了报刊一种事实上的自由.此后至1789年7月,法国社会各阶层拥护报刊自由的人士,在该决议的框架内主要通过小册子和陈情书来表达他们的诉求.大多数法国资产阶级人士强烈拥护报刊自由,他们希望完全废除审查制度.1789年,争取报刊自由的潮流极其猛烈,摇摇欲坠的旧制度已无力抵挡.  相似文献

Birth control movements that emerged in Europe and the United States during the last third of the nineteenth century lost their emancipatory and feminist potential in the twentieth century as they succumbed to control by the medical profession, eugenicists, and institutionalized goals of planned parenthood. The neo-Malthusian movement in France, however, retained a radical character and became a focal point for the convergence of libertarian, feminist, and anarchist concerns. By emancipating women from their "biological destiny" and separating sexuality and reproduction, neo-Malthusian rhetoric reconfigured womanhood and established the basis for women's development as full individuals and citizens.  相似文献

Cultural landscapes offer potential insights into cultural processes. As a cultural/political landscape element, the domestic campaign sign is linked to a variety of socio-cultural and political processes. Examination of the geographical distribution of 2004 presidential election campaign signs posted throughout the town of Hattiesburg, Mississippi, illustrates that race is a factor in understanding who chooses to post signs. Historically, limitations on political participation in the South would have included use of landscape for communication, imposing a sort of metacommunicative landscape hegemony. Further, patterns of sign postings and voter turnout indicate that both activities are forms of political participation that are embraced differently by different social groups.  相似文献

This study explores the spatial structure of retailing in Milwaukee, Wisconsin, in the era before the introduction of the electric streetcar in 1890. It uses city directory listings to chart changes in the numbers and types of retail outlets, their degree of nucleation and the functional complexity of such nucleations. The evidence suggests the early appearance of non-central retailing, the rapid dispersal of high as well as low order goods to non-central sites and the early emergence initially of a three-level and then, by 1870, a four-level hierarchy of shopping clusters. The pattern of retail clustering varied with the class and ethnic character of neighbourhoods, and clusters gravitated toward major arterial routes even in the pre-mass transit ear. Urban retailing in the second half of the nineteenth century was neither randomly dispersed nor over-whelmingly concentrated in a single central retail district, but developed a spatial hierarchy that clearly anticipated modern patterns.  相似文献

Relieving poverty amongst skilled but unemployed workers during the Tasmanian economic collapse in the 1890s challenged both a conservative government's policy of avoiding public debt by initiating minimal relief and the limited financial and human resources of voluntary philanthropic agencies, the Anglican Church amongst them, whom the Tasmanian governments expected to carry the burden of delivering relief to those deemed to deserve it. With labour organisations too weak to lead, and amidst the silence of church leaders, it fell to individuals like the Reverend Archibald Turnbull to articulate a Christian socialist critique of government policies and values and to advocate the desperate plight of the poor. In this context, this study examines how contemporary government and Anglican Church leaders responded to Turnbull's political and pastoral initiatives in Hobart in 1893–96.  相似文献

This article's focus is on the role of mothers in Simbo, one of the New Georgia islands in the western Solomon Islands. Mother's role is examined from the standpoint of the actual experiences of motherhood and mother's perceptions and reactions to child rearing, child care, burdensome tasks, and social participation. Anthropological studies emphasize non-Western notions of maternity or romanticize the primitive. Obscured in the process is who these women really are. Western feminist accounts of Third World women emphasize the oppression and uniformity of the "natural" mother. This characterization of Simbo women is presented as a single non-Western view and is unrelated to a global vision. Simbo women as mothers feel oppressed and are envious of Western notions of parenting, yet at the same time feel that Western child rearing deprives the child. Maternity is a state of ambivalence, where women feel both love for and oppression by children, spouses, and other women. The tasks and responsibilities of childbearing are more difficult because of increased fertility and changes in social practices. Women without children are viewed with sympathy and mild condescension. Changes in social practices are in part due to the presence of missionaries after 1903 and the over 200 year involvement of the islands in world trading. The most significant impact on women post-Christianity is the change from the emphasis on female-child relationships to male-female relationships. Pre-Christianity, marriage ceremonies stressed equality of spouses and their kin groups. New customs emphasize brideprice and the husband's authority over women's bodies. The change in power affects fertility levels, child care, women's work, and contraception. Men today do less labor relative to women and, when husbands are absent due to temporary labor migration, women may not have any help. The nuclear family is responsible for all labor. Women specifically tend the gardens and house, care for children, and care for ill members of the family. The concept of maternity changes with the stage in the life cycle. The first child is the easiest because grandmothers help with infant care. Children are both indulged and then resented when the demands interfere with activities or the children are too difficult.  相似文献
