Bruce L. Rhoads 《Geographical analysis》1991,23(4):346-361
Simultaneous-equation statistical models are an attractive method for directly analyzing interactions among components of geomorphic systems. This study demonstrates that the utility of simultaneous-equation analysis is limited for fluvial systems by inherent multicollinearity among hydrologic and morphologic variables. Although multicollinearity for observed data may not be severe, estimation procedures for simultaneous-equation models often enhance this multicollinearity to problematic levels. Diagnostic tests are applied to three models of fluvial systems to illustrate the severity of the problem. It is recommended that investigators who develop simultaneous-equation models perform appropriate diagnostic evaluations to determine the impact of multicollinearity on specific parameter estimates. 相似文献

Bruce G. Trigger 《Journal of Archaeological Research》1994,2(1):113-136
Publications and organizational developments relating to the history of archaeology from 1989 until June 1993 are critically examined. Attention is paid to the changing motivations for producing such publications, their shifting intellectual orientation, controversies, especially as they relate to internal vs external approaches and the epistemological status of explanations, problems of verification, and the status of these studies as a subfield within archaeology. 相似文献

Bruce Scates 《Gender & history》1997,9(2):285-309
The Great Strike of 1890 in Australia and New Zealand symbolized the rise of class, influenced nationalist discourse, and shaped labour politics. It also signified a crisis in gender relations. Conservatives and unionists openly contested the meaning of masculinity, mobilizing concepts of manhood in ways specific to class, community, ethnicity and age. Both groups were alarmed by the role women played in the dispute; attacks on scabs and special constables and the occupation of public, ‘male’ spaces challenged ascribed boundaries, customs and locales, and revived a rich tradition of pre-industrial protest. 相似文献
