This article addresses theoretical issues concerning differentiation and class formation using North American data. It explores how socio‐economic characteristics vary and impact survival in agriculture. The study is based on panel data collected from a sample of smallholders in three Piedmont North Carolina counties. Factor analysis reveals five major dimensions of differentiation: scale, household labour, off‐farm family labour and income, demographic characteristics, and land tenure. An index of propensity to survive in agriculture, constructed from three waves of panel data is regressed upon five indices measuring the underlying dimensions of differentiation. Land tenure manifests a statistically significant net effect on survival in agriculture. These empirical results support theoretical arguments in favour of integrating analyses of socio‐economic and demographic differentiation in the study of agricultural enterprises.  相似文献

In this paper the author focuses on Australian land management and in particular on the environmental management issues that could have been prompted by the High Court recognition in 1996 (in Wik Peoples v. The State of Queensland ) that native title to land and pastoral leaseholdings can co-exist. Drawing on themes of self-determination and co-existence, the paper looks at more specific topics such as aboriginal title to land—what has been called land rights or native title in Australia—and some implications of that for land, sea and resource management. Central to this analysis are competing theories of Aboriginal land management and links between Aboriginal traditional knowledge and conservation of species. These are illustrated through the marine mammal, the dugong. The Australian debates lead to the Canadian debates and then to Scandinavia and the role of the Sami people in protection and management of the Arctic region. Issues of indigenous self determination inevitably provide an overall theme to these discussions. As a matter of global concern, the paper asks, but does not decide, whether indigenous peoples may manage fragile eco-systems more effectively than outsiders. It maintains that what is important in this context is a broader question. This concerns how culturally inclusive land and resource management can emerge from recognition of indigenous land and human rights and how comparative developments can provide crucial cross-jurisdictional information for future developments and opportunities in the interests of environmental conservation.  相似文献

The detrimental effect of parental conflict in protracted child custody and visitation disputes is well established in the literature. However, little is known about the impact of parental conflict on children when visitation takes place in a protected setting. Part of a larger study that examined the broader issues related to parental and child involvement in a supervised access and custody exchange service, this article specifically explores the influence of parental participation on child well-being. This exploratory effort reveals that children's level of adjustment remained stable over 6 months of participation while visitation returned to court-ordered levels and interparental contact was precluded by staff intervention.  相似文献
