Using targeted survey, excavation, and radiocarbon dating, we assess the extent to which human settlement patterns on California’s northern Channel Islands fit predictions arising from the ideal free distribution (IFD): (1) people first established and expanded permanent settlements in the regions ranked high for environmental resource suitability; (2) as population grew, they settled in progressively lower ranked habitats; and (3) changes in the archaeological record associated with high population levels such as increases in faunal diversity and evenness in high-ranked habitats are coincident with the expansion to other areas. On Santa Rosa Island, the early permanent settlements were located in both high- and middle-ranked locations, with the most extensive settlement at the highest ranked locations and only isolated sites elsewhere. Settlement at a low-ranked habitat was confined to the late Holocene (after 3600 cal BP). Drought influenced the relative rank of different locations, which is an example of climate adding a temporal dimension to the model that episodically stimulated population movement and habitat abandonment. Because the IFD includes a wide range of cultural and environmental variables, it has the potential to be a central model for guiding archaeological analysis and targeted field research.  相似文献

Based on existing work, there are clear differences in the incidence of degree holders across the urban–rural hierarchy in favor of large urban areas. In large part, this gradient can be traced to the higher probability of obtaining a degree among residents of larger urban centers. Utilizing data from the Youth in Transition Survey (YITS), this paper explores factors that may account for university participation among Canadian youth. It asks whether this difference is due to local access to universities, family characteristics (e.g., parental income, education, and immigrant status), and local labor market characteristics that may increase the incentive for urban youth to attend university.  相似文献

This paper provides a unique perspective on trust in Australian society using data from the first wave of a longitudinal study of young people in Queensland. Questions central to young people's expectations regarding institutions and significant others are interrogated. Trust assumes critical importance in this context because it is an important aspect of the future-oriented deliberative processes young people engage in. Gender, indigenous status and religiosity are key determinants of trust across a range of indicators. Boys are less likely than girls to trust significant others such as friends and siblings or to trust environmental groups, but are more trusting of sportspeople, television and the Internet. Aboriginal children are more trusting of their siblings, teachers and neighbours, but less so of their parents. ‘Smart’ children are more trusting of their teachers and schools and feel more confident about their future, while general life satisfaction is positively associated with most measures of trust.  相似文献
