The site of Combe-Grenal is arguably the reference site for the Mousterian of southwest France. Bordes excavated the site over a period of 13 years and generated a large collection of lithics and fauna from a deep series of 64 Lower and Middle Paleolithic levels. Though Bordes only partially published his work at the site, its long stratigraphic sequence and particularly its collections have been subjected to numerous studies over the years and have figured prominently in several long-running debates concerning the Mousterian. Recently, the authors undertook a project to inventory and analyzed these collections along with the documentation of their archaeological context. In so doing, however, a number of serious problems became apparent with the collection in its current state, problems that cannot easily be resolved given the state of the available documentation. These problems have important implications not only for results of studies based on these collections, but more generally, they also point to problems in terms of how archaeological collections are curated.  相似文献

The seismic vulnerability of housing stock in El Salvador was demonstrated during the recent 2001 earthquakes. Relative to other types of common residential construction, confined masonry dwellings performed well. A coordinated pilot study was conducted with the objective of improving the seismic resistance of this form of construction while reducing associated costs and greenhouse gas emissions. Laboratory tests examined brick strength in relation to firing temperature and duration. Analytical studies examined the potential for voided bricks to improve seismic performance, the reduction in demands associated with stiffening the roof diaphragm, and demands imposed on the roof bracing system. This pilot study identifies the potential for voided bricks to reduce construction costs and greenhouse gas emissions with negligible effects on performance. The addition of end-bay diagonal bracing at the roof level resulted in significant performance enhancements.  相似文献

In the wake of ecological crises, there has been a resurgence of interest in the relation between dialectical thought and nature. The work of Herbert Marcuse and Murray Bookchin offers unique approaches to this question that remain highly relevant. In the first half of the article, we engage with Marcuse's application of the dialectical method in which he gestured to the “vital need” to push beyond the appearance of “the real” and yet lamented the loss of the ability for negative thinking to pierce the dominance of the “technical apparatus” that tied humanity to this “radical falsity”. Here, we suggest the need for a more holistic dialectical understanding of the social totality—one that is directly located within, and takes as foundational, the environmental conditions of human society. In the second half, we examine Murray Bookchin's conception of “dialectical naturalism” as a more thorough engagement with the human/nature relation that surpasses Marcuse's late engagements with ecologism. In particular, we offer critical reflections on the concept of “nature” in the contemporary ecology movement and illustrate how dialectical naturalism is capable of not only transcending dualistic conceptions of “man/nature” but in expanding our awareness of the potentialities of history along what Bookchin terms the “libertory pathways” to a restorative relation between human “second nature” and biological “first nature”. We posit that systemic, interconnected and accelerating ecological crises (climatic, biospheric and oceanic) form the objective and absolute contradiction of contemporary global social life that compels an awareness of the potentialities of an ecological society. Only through this awareness can we break through the reified “solutions” that have often plagued the ecology movement, bringing about the urgent social and ecological transformation that our species requires for its liberation and long‐term survival.  相似文献

While lithic objects can potentially inform us about past adaptations and behaviors, it is important to develop a comprehensive understanding of all of the various processes that influence what we recover from the archaeological record. We argue here that many assumptions used by archaeologists to derive behavioral inferences through the definition, conceptualization, and interpretation of both individual stone artifact forms and groups of artifacts identified as assemblages do not fit squarely with what we have learned from both ethnographic sources and analyses of archaeological materials. We discuss this in terms of two fallacies. The first is the fallacy of the “desired end product” in stone artifact manufacture, which also includes our ability to recognize such end products. The second fallacy has to do with the notions that lithic assemblages represent simple accumulations of contemporary behaviors and the degree to which the composition of the depositional units we study reliably match the kinds of activities that took place. Although it is beyond the scope of this paper to offer a comprehensive set of new methodologies and theoretical perspectives to solve these problems, our goal here is to stress the importance of rethinking some of our most basic assumptions regarding the nature of lithic objects and how they become part of the archaeological record. Such a revision is needed if we want to be able to develop research questions that can be addressed with the data we have available to us.  相似文献
