Local earthenware associated with enslaved African populations in the Americas, variously called Colono-Ware, Afro-Caribbean Ware. Yabbas, and Criollo ware, has received considerable attention from researchers. What unifies this disparate group of ceramics is not method of manufacture, design and decoration, or even form and function but the association or potential association with African diaspora populations. The ceramics incorporate some skills and techniques possibly brought by African potters to the Americas, as well as skills reflecting European and Native American traditions, and local adaptations in form, function, and manufacture. Analogies linking African ceramic traditions to American industries have at times been employed uncritically and have relied on generalized characteristics to infer overly specific meanings. With particular reference to low-fired earthenwares from Jamaica, this paper examines the historical and cultural context of these ceramics and the methodological and theoretical problems faced in their interpretation.  相似文献

关于中国早期国家的几个问题   总被引:5,自引:0,他引:5  
目前学术界对有关中国早期国家的概念存在着分歧.我们认为中国早期国家是指夏商周三代已具备公共权力,但社会仍滞留在居民血缘组织基础之上的政治组织.所谓中国在龙山时代就已出现了早期国家的说法是不能成立的.至于中国早期国家的产生,则是走的部落联盟酋长因其职务的“独立化“转变为“社会主人“这样一条路径.  相似文献

Archaeologists can learn from models of evolution as a self-organized critical phenomenon. Self-organized critical systems are large, interactive systems that organize into a critical state where minor events can trigger chain reactions. Such systems demonstrate power-law distributions in the size of changes, or avalanches, that occur. The theory of self-organized criticality is important in that it implies that the evolution of complex systems may be driven more by interactions between agents than by external events or natural selection. Stylistic changes may be examples of avalanches of interconnected events. Evidence for self-organized criticality is shown for stylistic evolution in historical pottery styles from New York State and is used to evaluate the nature of a prehistoric pottery typology from the Southwest.  相似文献

Stable oxygen isotope ratios in archaeological human dental enamel represent an under‐utilised tool in the examination of changing climatic patterns in the ancient world. In the Oman Peninsula at the end of the third millennium bc , rapid aridification was accompanied by a breakdown in interregional trade relations; however, the human response to these changes is poorly understood. At the Bronze Age necropolis at Shimal in the United Arab Emirates, dental enamel from individuals interred in both Umm an‐Nar (ca 2700–2000 bc ) and Wadi Suq (ca 2000–1300 bc ) tombs underwent oxygen, strontium and carbon isotope analyses to examine how local inhabitants of southeastern Arabia responded to both environmental and socioeconomic change. While individuals from Shimal exhibit a clear shift in mean δ18Oc(VPDB) values from the Umm an‐Nar (−3.5 ± 0.6‰, 1σ) to the Wadi Suq (−2.4 ± 0.9‰, 1σ), corresponding 87Sr/86Sr and δ13Cap signatures display homogeneity indicative of continuity in Bronze Age lifeways. Together, these data highlight the ability of local communities to successfully adapt to their changing environs (in lieu of societal collapse or a shift to a more mobile lifestyle) in an effort to maintain their way of life.

Historians have taken a beating in recent times from an array of critics troubled by our persistent unwillingness to properly theorize our work. This essay contends that their criticisms have generally failed to make headway among mainstream historians owing to a little noticed cognitive byproduct of our work that I call history as philosophy. In so doing I offer a novel defense of professional history as it has been understood and practiced in the Anglophone world over the last half‐century or so while suggesting, in conclusion, that historians could not do other than they do without serious psychic and societal loss.  相似文献

Many studies have documented the benefits of urban agriculture, including increased food access, job creation, educational opportunities, and green space. A focus on its social benefits has fed an association of urban agriculture with social justice, yet there is a distinction between alleviating symptoms of injustice (such as disparate access to food or environmental amenities) and disrupting structures that underlie them. Despite its positive impacts, urban agriculture systems may reinforce inequities that practitioners and supporters aim to address. This paper reports findings from a 2‐year study of urban agriculture in New York City, which found race‐ and class‐based disparities among practitioners citywide. Using the lens of critical race theory, it argues that a failure to examine urban agriculture's role in either supporting or dismantling unjust structures may perpetuate an inequitable system. The paper concludes with recommendations for urban agriculture supporters and scholars to help advance social justice at structural levels.  相似文献

Following the spontaneous occupation of Madrid's Puerta del Sol in 2011, many academic accounts have found these mobilizations new and noteworthy for their technological savvy and networked capabilities. In this article, I argue that such depictions fail to capture both the influence of Spanish urbanism's material conditions on certain disadvantaged populations, and the broad diversity of these contemporary activisms. Looking to struggles over the proposed demolition of a squatter settlement in Madrid, I demonstrate how Madrid's planning has propagated racial imaginaries to legitimate dispossession and subvert anti‐poverty policies. Second, I examine how resistance and contestation emerge out of specific urban experiences of inequality, and transcend traditional modes of activist organizing through the formation of broad coalitions between various civil society actors. In doing so, I argue that Madrid's mobilizations have paradoxically opened new avenues for the inclusion minority voices, against popular understandings that read rising xenophobia during crisis.  相似文献

Voluntary programs have emerged as important instruments of public policy. We explore whether programs lacking monitoring and enforcement mechanisms can curb participants’ shirking with program obligations. Incentive‐based approaches to policy see monitoring and enforcement as essential to curb shirking, while norm‐based approaches view social mechanisms such as norms and learning as sufficient to serve this purpose. The United Nations Global Compact (UNGC), a prominent international voluntary program, encourages firms to adopt socially responsible policies. Its program design, however, relies primarily on norms and learning to mitigate shirking. Using a panel of roughly 3,000 U.S. firms from 2000 to 2010, and multiple approaches to address endogeneity and selection issues, we examine the effects of Compact membership on members’ human rights and environmental performance. We find that members fare worse than nonmembers on costly and fundamental performance dimensions, while showing improvements only in more superficial dimensions. Exploiting the lack of monitoring and enforcement, UNGC members are able to shirk: enjoying goodwill benefits of program membership without making costly changes to their human rights and environmental practices.  相似文献
