Geographic inequality and racial disharmony are considered major factors in America's political divergence. This paper calculates geographic earnings inequality from 1960 to 2016 separately by race. From 2000 to 2016, White geographic inequality was significantly higher, and Hispanic geographic inequality was significantly lower, than Black and Asian geographic inequality. White geographic inequality rose from 1980 to 2008. Black and Hispanic geographic inequality fell from 1960 to 1980. Rural controls explain substantial shares of White geographic inequality in all years. Region and rural controls account for large shares of Black geographic inequality, especially from 1960 to 1990. Post-1990, geographic inequality changes are largely explained by changes in overall earnings inequality, but 1960–1990 changes are not. Between-race differences in geographic inequality translate into high-income metropolitan statistical areas having had, since 1980, significantly smaller shares of Whites among their low-income residents. 相似文献

ABSTRACTAcross a number of disciplines at the University of Aberdeen, there is a long tradition of research focused upon the interrogation of issues associated with rural places and rural communities. Since the mid-1960s, rural geographical research has been a prominent component of the research undertaken by academic staff in Geography. Drawing upon an analysis of the large corpus of ‘rural’ publications arising from this scholarly enterprise, this paper presents a chronologically structured overview of how rural geographical research at Aberdeen has reflected developments in, and contributed to, the evolution of the sub-discipline of rural geography. 相似文献

Collapsing Commodities or Lavish Offerings? Understanding Massive Metalwork Deposition at Langton Matravers,Dorset During the Bronze Age–Iron Age Transition 下载免费PDF全文

The discovery of 373 intact and broken tin‐bronze socketed axes accompanied by 404 fragments in four pits at Langton Matravers collectively represents one of the largest hoards found to date in prehistoric Britain and Ireland. They were very probably never meant to be used as axes as the very high levels of tin they contain would have made them brittle. Many were poorly finished, with the majority still containing their casting cores. The axes are typologically dated to the Llyn Fawr metalwork phase (c.800–600 BC) and span the Bronze Age/Iron Age transition, when the production, circulation and deposition of bronze appear to have been substantially reduced throughout north‐west Europe. By placing the Langton Matravers hoard(s) in a broader metallurgical, material and archaeological context, existing theories for this phenomenon, such as the preference for iron, a collapse in bronze supply, or the sharp devaluation of a social or ritual ‘bronze standard’, are evaluated. It is proposed that the Langton Matravers axes belong to a short phase in the centuries‐long processes underlying the changing roles of bronze and iron. 相似文献
