Thomas Willis made numerous contributions to the neurosciences that were broad in scope. In an age of scientific breakthroughs and intellectual revolutions, Willis bestowed upon medical research the clinical rigor that set the stage for subsequent medical breakthroughs. In Cerebri Anatome, Willis introduced a measure of empiricism hitherto unknown in medieval times. By coupling the delineation of brain and neural anatomy with functional studies, Willis brought the science of clinical neurology into fruition. Psychiatry, too, benefited from Willis' elucidation of mental illness and intellectual disability, and modern behavioral psychologists claim Willis as one their early, most ardent champions.  相似文献

Chicago's remarkably flexible growth machine, like their brethren across Rust Belt America, continues to aggressively press forward to build an internationally competitive city. This paper deepens our understanding of Chicago's recently changed growth machine. It focuses on its current redevelopment narrative as it is used on the South Side and chronicles two new features about it: its revamped use of fear and its re-fashioned notion of culture. I flesh out these two elements as they circulate through a now dominant redevelopment program: historic preservation. I chronicle three points in this paper. First, programs like historic preservation, like so many current city programs, have now fully shifted to being a neoliberal economic development tool to promote the “go-global Chicago” project. Second, two dominant fears recently nuanced anchor the narrative: fear of a city-destroying globalization and fear of city-subverting poor African-Americans. Third, a revamped notion of culture is used that helps provide resonance and dark appeal to the two offered fears. The culture notion is put into play as two dominant things, as the idealized and timeless glue that unifies Chicago's mainstream and as problematic values and meanings carried by black bodies which renders them civic tainting “ocular trash”.  相似文献

The Rio Grande border of the United States and Mexico is over 1,000 miles long. This presentation of that border is by means of a photo essay interpreting the physical, economic, political, and cultural complex that has evolved. These photos were all taken in 1990 on a reconnaissance that followed both sides of the border for the entire distance from Ciudad Juarez and El Paso on the west to the Gulf of Mexico on the east. Numerous crossings of the border were made at official and non-official points. Informal field interviews were conducted on both sides of the border with government officials, agricultural workers, tourists, farmers, industrial managers, factory laborers, retirees, undocumented migrants, beachcombers, shoe-shiners in the plaza, sportsmen, clergymen, children, and loafers. The photos with an accompanying text are presented in an order that is conducive to a comprehension of the salient aspects of the physical and human geography and the complex social issues found in the borderland. The final photos and text are on the maquiladoras and the international interplay of history, markets, labor, and technology resulting in striking structural change.  相似文献

This article examines how concepts of ‘play’ can be used within studies of cultural heritage to build an alternative to the dominant use of consumer-orientated models within current scholarship. Using the example of how the traditions, motifs and history of Ancient Greece have been reused within New York, from the nineteenth century to the present day this work demonstrates that this is a heritage that has been ‘played with’ by successive generations as a means of establishing identity within the metropolis. Whilst the ideals of Athenian democracy and classical learning inspired the formation of the early American republic, these associations were brought into wider usage in New York with the arrival of significant Greek immigration into the city during the twentieth century. This provided a new opportunity of a playful use of Ancient Greek heritage as this émigré community built new identities and became established in the metropolis. The Greek American enclave of Astoria, located in the borough of Queens, will be the focus of this study as the site where this playful use of heritage has taken place, undertaken both by members of the Greek American community and also by individuals and groups responding to their presence.  相似文献

Many ecofeminists see women's subordination as a result of linking women with nature. Thus one of their tasks has been to unravel the underlying dualistic structure of the categories ‘women’ and ‘nature’ and to argue for a reconceptualization of these categories. However, there exist amongst ecofeminists epistemological differences pertaining to the ways in which the women–nature connection should be addressed. Spiritual ecofeminists argue that the connection between women and nature is worth reclaiming and celebrating. In contrast, social ecofeminists contend that the connection represents a patriarchal artifice that reinforces oppression. In support of both perspectives, ‘Western’ ecofeminists have invoked the cultural beliefs and histories of Aboriginal peoples. Such use of Aboriginal beliefs and experiences within much of Western ecofeminist discourses is partial and uninformed. In this article an alternative approach is offered—one that emphasizes the importance of listening to Aboriginal voices describing contemporary connections to nature. Aboriginal voices are presented in the context of in-depth interviews conducted with Anishinabek (Ojibway and Odawa peoples) living in one First Nations community and three cities in Ontario, Canada. The interviews highlight the importance of listening to Anishinabek describe their connections to Mother Earth (nature) as they reveal counter-narratives that offer the potential to reconcile spiritual and social ecofeminism and to reconceptualize nature (Mother Earth) as an active and dynamic agent. Such counter-narratives may improve current understandings of gender–nature connections within Western ecofeminisms.  相似文献

In this study, we attempt to relate hydrologic regimes of the 1997 flood in the Red River Valley to the areal extent of flooding, determined from RADARSAT imagery. We obtained ten scenes of RADARSAT imagery, from 27 April to 1 July, including bitmaps delineating flooded areas for each date, from the Manitoba Centre of Remote Sensing. These images were co-registered using an image-to-image registration process. By overlaying these flood maps in chronological order, we compared the areal extent of flooding with the hydrologic regimes of the Red River, expressed as relative depths of flooding above the bankful stage at selected gauging stations. The results of the study indicated that the area of flooding on 4 May (1,984 km 2 ) corresponded well with the highest flood levels at several gauging stations. A previous scene on 27 April showed a larger area under water, but visual inspection of the processed imagery indicated a lack of conformity between flood level regimes and the areal extent of flooding on this date due to surface detention of pre-flood storm runoff. Thus, the RADARSAT imagery represented the flood regimes adequately only when its interpretations were combined with hydrologic analysis and visual inspection of surface characteristics of the floodplain.  相似文献
