Mexico’s Central Highlands form one of Mesoamerica’s fundamental cultural seams, a point of overlap between two traditions, one to the east and the other to the west. Although this area is usually included in the west, it can be more productively viewed as an interface, the physical space where people, goods, and ideas passed from one side to the other, and thus it holds many keys for our understanding of emerging social complexity in Mesoamerica. In reviewing the last two decades of Formative period (1500 BC–AD 100) research in this crucial territory, we focus on themes that reveal the variation and dynamism of interregional interaction, including the formation of regional traditions, exchange systems, and foreign “influence,” and others that help contextualize the events and processes of that time, like household studies and environmental degradation. We stress that this part of Mexico is undergoing relentless development so time is of the essence if we are to broaden our perspectives on social evolution in the Central Highlands. This issue cannot be resolved by rescue and salvage work because it requires long-term, interdisciplinary projects to unravel multifaceted problems.  相似文献

In Picturing Heaven in Early China,a consideration of the symbolism of Heaven in early Chinese culture,Lillian Lan-ying Tseng examines the evolution of a pictorial language for the expression of "religious" ideals.By analyzing the architectural,material and literary evidence from the Han dynasty,the author traces the trajectory of Han thought from its first concerns with the notion of Heaven and the involvement of the emperor,to the growing desire for personal immortality at all levels.The book comprises five chapters,which plot the development of Han thought and images of heaven.This is a complex and well-researched examination,whose depth and detail can only be suggested here.  相似文献

Situated within the political ecology of hazard, this article is an extended case study of the devastating 2003 wildfires in and around Kelowna, British Columbia (also known as the Okanagan Mountain Park Fire). This article reveals how compliance (or lack thereof) with fire mitigation strategies recommended by provincial, regional, and municipal agencies is complicated by differing social constructions of what constitutes ecologically sustainable forest management and community safety. Three perspectives emerge regarding the urban forests: “nature as hazard”—a volatile force to be controlled; “nature as instrumentally valuable”—a contribution to the character of one's surroundings and subsequent sense of place; and “nature as intrinsically valuable”—a distinct entity to be preserved and protected for its own sake. The article also examines how experiences of disaster influence community perceptions and result in a greater willingness to engage in fire mitigation strategies due to perceptions of heightened vulnerability. Forestry and fire mitigation agencies need to determine multiple courses of action among the varied and valid range of residents’ nature perspectives. The role of human agency in disaster mitigation must be examined, particularly as the risk of fire at the wildland‐urban interface continues to be exacerbated by encroaching human settlements and climate change.  相似文献

Benson, R.B.J., Fitzgerald, E.M.G., Rich, T.H. & Vickers-Rich, P., 2013. Large freshwater plesiosaurian from the Cretaceous (Aptian) of Australia. Alcheringa 37, 1–6. ISSN 0311-5518

We report a large plesiosaurian tooth from the freshwater early–middle Aptian (Early Cretaceous) Eumeralla Formation of Victoria, Australia. This, combined with records of smaller plesiosaurian teeth with an alternative morphology, provides evidence for a multitaxic freshwater plesiosaurian assemblage. Dental and body size differences suggest ecological partitioning of sympatric freshwater plesiosaurians analogous to that in modern freshwater odontocete cetaceans. The evolutionarily plastic body plan of Plesiosauria may have facilitated niche differentiation and helped them to exclude ichthyosaurs from freshwater environments during the Mesozoic. However, confirmation of this hypothesis requires the discovery of more complete remains.

This article examines how younger migrant women from Turkey maneuver the public and private spaces of their everyday lives in a neighborhood in Germany, and how they challenge and affirm the patriarchal practices and gender norms that husbands, fathers, and older migrant women seek to impose within and outside private homes. Younger migrant women selectively comply with gendered and generational norms of veiling and dress, while at the same time also reworking gender roles, and avoiding and transgressing masculinist spaces. Younger migrant women's practices and spatial representations in mental maps reveal the complex entanglements of compliances and resistance, and dispel simple assumptions of being overwhelmingly victimized by their potentially violent men that are so prominent in contemporary Western societies.  相似文献
