Marriage in Western European society was the preserve of the Christian Church throughout the later middle ages. The law of the Church played a significant role in the formation of doctrine concerning that institution, including the sexual relationship of spouses. Adopting a debt-model of conjugal relations, the canonists maintained that each partner owed marital coitus to the other. The lawyers emphasized the mutually binding character of this obligation, and consistently dejended the right of spouses to exact their marital due, insisting that this duty could be abrogated only by mutual consent. As heirs to an ascetic patristic tradition, however, the lawyers tended to be suspicious of fleshly pleasure. A peculiar and ambivalent doctrine resulted from this tension between an appreciation of the intrinsic goodness of the married state and a distrust of sex, one of its major constituents.  相似文献

Landcare is a response to the land degradation crisis facing Australia and is both a community process and a government policy. ‘Landcare’ is a contested term with different meanings being placed on it by individuals and groups from different places with different levels of power and local knowledge. A key concept of Landcare is forming partnerships, which are also seen in very different terms by various Landcare stakeholders. Landcare places great value on local environmental knowledge and senses of place. The achievements of Landcare in facilitating cultural change are assessed and the factors identified that will determine whether Landcare can be ‘scaled up’ to address wider issues of ecological sustainability.  相似文献

South Korea experienced below replacement fertility for the first time in 1983, which also marked the point from which fertility rates continued to decline over the next 20 years to reach a low of 1.2 in 2003. In spite of recent pronatalist policies, the fertility rate has remained near this level and has not increased appreciably. The reasons for sustained low fertility in South Korea are complex and solutions remain elusive. One option that has been suggested is reunification with North Korea, which could address the eventual decline in the population and mitigate the increasing proportion of the elderly. Although the conditions surrounding the German reunification experience were vastly different than what Korea will likely undergo, it is informative to look at Germany as a guide to the demographic parameters of reunification. Three projection models for 2015–2050 are presented; even the highest fertility models show that reunification will not be the answer to population restructuring already underway in South Korea as a result of sustained low fertility.  相似文献
