We compare the relative impacts of political and socioeconomic factors on state restrictiveness toward abortion during the pre-Roe, pre-Webster and post-Webster time frames. This analysis tests the value of cycle theory, where shifting epochs dominated by liberalism and conservatism enhance the role of political variables in shaping policy formation. It also tests the explanatory value of public opinion theory which holds that bimodal issues which cut across party lines accentuate the role of socioeconomic variables in shaping issue evolution. The results of this analysis lend support to cycle theory and public opinion theory, although public opinion theory receives stronger support. When socioeconomic independent variables are regressed against our dichotomous measures of state restrictiveness toward abortion, they explain more variance than political independent variables. Political variables were more important in the conservative era (1989) than in the liberal era (1972). 相似文献

In West Africa, containment practices have long been localized in their production, moulded by environmental forces, and scaled to the human body. In the twentieth century, fossil fuels have changed how people keep and carry things. But newer technologies have tended to alter, rather than eliminate, older forms of storage. 相似文献

It is generally thought, largely on the basis of a letter of Cardinal Bessarion, that, by the 1440s, the Byzantine Empire had been completely overtaken by the West in all spheres of technical expertise. This idea is challenged the evidence of some documents the Public Record Office in London which show that, between at least 1441 and 1483, two gold wire drawers from Constantinople, named Andronicus and Alexius Effomatos, lived and worked in the English capital. It is argued that these craftsmen were welcomed because they specialised in making gold thread of a type which had long been manufactured in Byzantium but was superior in strength and economy to that produced in England. Indeed, since the earliest evidence for native English production of this type of gold thread dates from the period of their residence in London, there is at least the possibility that they actually introduced their craft into England, reversing the relative balance of technology as it is usually portrayed. 相似文献

ABSTRACT. The occurrence of rural retail activity may be related to the concept of threshold, which suggests the direct relationship between surrounding populations and the hierarchical functions provided. Empirid studies have typically examined individual categories of retail firm concentration or multiplication in isolation of the extent of other retail activities. This study develops models of retail business concentration for sparsely populated rural markets, and emphasizes proper statistical treatment of the discrete firm-count data. The analytical approach specifies systems of multivariate count data models that can capture the interdependencies among merent types of retail firms. The degree of interdependence is tested and shown to be a significant statistical feature of the model of rural retail firm counts. 相似文献

Augustus claimed that the moral decay of the Roman Republic was especially due to Roman women who had forsaken their traditional role of custos domi (‘preserver of the house/hold’). In reforming feminine morality, Augustus created a new pictorial language that troped the feminine body as a ‘moral sign’ of civic morality and authorized a distinctive costume for women. Sebesta investigates the relationship between women’s garments, the female body and the Roman concept of feminine civic morality. 相似文献

Roller explores the evidence for eunuch priests who castrated themselves to honour the Great Mother Goddess Cybele. While the custom of sacred eunuchism originated in Phrygia (in central Turkey), such priests are best attested in Greek and Roman society, where they were viewed with disgust and loathing because of their asexual condition and because they adopted the dress, hairstyles and mannerisms of women. The negative reactions to the eunuch priest rest on an unspoken assumption of the superiority of masculine appearance and of the inviolability of appropriate gender roles for men and women. 相似文献

In the time interval between approximately 2.5 million years and 1.5 million years ago and against a background of changing environmental conditions and the emergence of highly diversified populations of early hominids, the earliest archaeological occurrences have been documented from a number of localities in the Rift Valley of East Africa. These have been attributed to the Oldowan Industrial Complex. More recently, broadly comparable archaeological occurrences have been discovered from Hadar and the Middle Awash located in adjacent areas of the Afar, in Ethiopia. This paper summarizes the age, context and characteristics of these occurrences and offers preliminary comments on their contribution to greater understanding of early hominid adaptive patterns of behavior. 相似文献
