From 1900 to 1902, the General Federation of Women's Clubs' official commitment to "unity in diversity" was tested to the limits when an explosive debate over the admission of African American women's clubs deeply, and in some cases irreparably, divided individual clubs and state federations and nearly resulted in the loss of half of the organization's burgeoning membership. The controversy reveals a captivating, complicated, and at times bizarre struggle between Northern and Southern white members of the General Federation to defend their particular views of race and, in many cases, to obfuscate their own deep-seated racial prejudices. Most members ultimately sacrificed principle for the sake of federation unity, albeit a unity without racial diversity, and thus squandered the opportunity to combine the talents and energies of all organized women in an effort toward social justice and humanitarian reform.  相似文献

The islands of Western Torres Strait, between Papua New Guinea and Australia, saw the emergence of ritual dugong bone mounds approximately 400 years ago. These mounds were used as a means to commune with, and as an aid for the hunting of, dugongs. This paper explores the bone contents of three dugong bone mounds on the small, uninhabited island of Koey Ngurtai as a means to determine their construction and in doing so to explore the historical emergence of ritual bone mounds associated with dugong hunting magic—and thereby to historicise ethnographically known cultural practices—in Torres Strait.

ABSTRACT

Kettle Falls, located 1125?km from the mouth of the Columbia River in present-day Washington State (USA), was the second-most important salmon fishing and trading locus on that river in the early historic era. We encapsulate the late Holocene history of the fishery by deriving a summed probability distribution function (SPDF) from 50 radiocarbon ages from 13 archaeological sites within 2?km of the falls. When compared to an SPDF from 307 sites from elsewhere on the Columbia Plateau, and a null model, the Kettle Falls SPDF exhibits two phases of elevated activity at 1700–1300?cal BP and 800–500?cal BP, and an intervening lull. These phases are not related to the excavation history or differential exposure of sites to taphonomic processes, but they are concordant with episodes of glacial advance in the local mountains, which reflect hemispheric-scale changes in climate. Modern returns of summer-run Chinook salmon to the Columbia River are inversely correlated with sea-surface temperature regimes in the northeast Pacific Ocean, and we propose that the occupational history of the Kettle Falls fishery echoes long-term variations in the returns of salmon to the upper Columbia River linked to climate change.  相似文献
