Thin-section study of Mesolithic-Neolithic axes from five sites in eastern central Sweden and of dolerites occurring in the vicinity showed that the axes were almost definitely produced from local material. Knapping experiments were carried out on blanks from two of these local dolerite varieties and on control material from Delaware, New Jersey, to produce thin-butted axes. These showed that the unconventional shape of the Swedish preforms is mainly, if not completely, determined by the intrinsic properties of the rock and not by local or regional cultural differences or bad craftsmanship. A number of features were observed in thin-section, such as a relatively coarse grain size, veining and small cracks, which may lead to the inferior knapping qualities of the Swedish dolerites. 相似文献

THE IMPACT OF ECONOMIC OPPORTUNITY, AMENITIES AND FISCAL FACTORS ON AGE-SPECIFIC MIGRATION RATES 总被引:5,自引:0,他引:5
ABSTRACT. Migration models have considered several different categories of determinants, including economic opportunities, amenities, and state and local fiscal factors. Migration has also been shown to depend on the individual's position in the life cycle. This paper represents a first attempt to integrate all three categories of determinants of migration into a life-cycle framework. Empirical findings generated from a countrywide model of white male migration, over the period 1970 to 1980, reveal that all three types of determinants are important. Specifically, economic opportunities are most influential for males during their working years. Amenities are also found to follow a life-cycle pattern with older migrants more attracted to amenable locations than their younger cohorts. Finally, state income and death taxes display life-cycle effects; working males in their peak earning years are detracted by high income taxes while all migrants aged 55 to 69 avoid counties in states with high inheritance and estate taxes. 相似文献
