The loss of farmland in four counties of south-central Ontario was examined for the 1951–71 period, with the use of township census data. The study has indicated the need to be cautious regarding the accuracy of official statistics. Regression analysis of the census data revealed that the best predictor of farmland loss was the extent of part-time farming. Since 1971, the role of part-time farming has changed greatly. The percentage of part-time farmers is increasing steadily because off-farm income is vital to the maintenance of the economic viability of farming today. In contrast to the 1950s and 1960s, the part-time farmer now is often coming into full-time farming rather than phasing out. The results of this analysis present further evidence of the complexity of the loss-of-farmland problem and the variability of the findings that emerge from studies conducted for different periods 相似文献

In this article the author discusses the projected enlargement of NATO, focusing on the candidacy of the three Baltic states. He examines the factors that have induced the Baltic governments to seek NATO membership, the steps the alliance has taken in the lead–up to the Prague summit in November 2002, the evolution of US policy with regard to the potential entry of the Baltic states into NATO, and the arguments that have sometimes been raised against Baltic membership. He argues that the admission of the Baltic states into NATO will be a step forward both for the alliance and for European security, but he believes that it should be accompanied by a restructuring of the alliance that would give much greater weight to its political dimension. One key objective of this restructuring would be to establish a closer relationship with Russia, moving beyond the NATO–Russia Council that was set up in May 2002. The way to do this is not by treating Russia as a special case, but by encouraging the Russian government to apply for NATO membership (as other countries have) and then helping Russia to carry out far–reaching political and military changes that would eventually qualify it to enter the alliance. 相似文献

This article presents and discusses a corpus of worked and decorated shell discs from recently excavated archaeological sites in southern Arabia, including Dibba (northern Oman), Saruq al‐Hadid (UAE) and Sumhuram/Khor Rori (southern Oman). The artefacts are compared to a wide range of shell discs from controlled excavations in Arabia and the broader Near East in order to better understand their date, manufacture and use. The comparative study highlights the wide distribution of decorated shell discs across the ancient Near East, particularly during the early Iron Age, and the complex economic and cultural connections that underpinned the collection, crafting, exchange and significance of such items. 相似文献

This paper investigates the role of specialized production strategies in the development of socio-economic inequalities in Bronze Age south-eastern (SE) Arabia, and particularly, the ways in which a localized, internal exchange economy may have produced stress and instability in the SE Arabian socio-economic system. While archaeological research has established that the communities of SE Arabia participated in a widespread Bronze Age exchange system that included areas of the ancient Near East, South Asia, and Central Asia, it is unclear to what degree this interaction fostered the broad-scale socio-economic changes seen in the Early Bronze Age of SE Arabia. Here we present the results of an agent-based model that suggest the nature of the internal exchange economy in SE Arabia itself may have precipitated the social conditions necessary for change by allowing individuals to profit disproportionately. We thus emphasize the importance of local production strategies in generating socio-economic change, in addition to the well-established economic and cultural contacts with the wider Bronze Age world. 相似文献
