Several researchers have suggested use of watercraft during the Early Paleoindian period 11,500 and 10,800 rcybp (13,400–12,700 cal B.P.), but none have brought empirical data to bear on this possibility. This paper addresses the potential for fluted point-making groups to have made and used boats circa 11,000 rcybp (13,000–12,800 cal B.P.). Fluted point data from a large region of the upper and central Mississippi River valley strongly suggest that the Mississippi River was a barrier to movement and that Early Paleoindians in the midcontinent did not routinely use watercraft.  相似文献

Lithic artifacts from the lowest strata of the Debra L. Friedkin site, located on Buttermilk Creek in central Texas, have been interpreted as an undisturbed pre-Clovis assemblage (Waters et al., 2011a). Stone tools and debitage were recovered from sediments stratified just below diagnostic Clovis artifacts and dated by OSL to between 13.2 and >15.5 cal kya. Invoking commonly observed cultural and natural site formation processes, we offer an alternative explanation of the “Buttermilk Creek Complex” as a Clovis assemblage in secondary association with the dated sediments.  相似文献

This paper considers T.H. Green's theory of property in relation to recent studies of late nineteenth and early twentieth century liberal democratic thought. It is argued that neither the ‘Marxist’ spectacles worn by C.B. Macpherson nor the ‘Whiggish’ ones of Melvin Richter, Peter Clarke and Stefan Collini produce very clear or accurate images of Green's political philosophy. Macpherson's Green appears on close examination as yet another possessive individualist, while the ‘Whigs’ take a turn of the century standpoint and describe Green as holding positions that are ambivalent and fit awkwardly into the categories of individualism/ collectivism. In the remainder of the paper it is argued Green's property theory is best understood by focussing on his interest in the relationship between social life and personal development. By drawing on Green's published and unpublished writings it can be shown that Green's idea of personal development could be expressed in other language than that of economic individualism and that it cut across the individualist/collectivist categories in terms of which it is often discussed.  相似文献

In this article, we explore how normative ideologies of good mothering are being reproduced and contested through urban homesteading, a sustainable lifestyle that emphasizes household self-provisioning. Urban homesteading practices may include gardening and urban agriculture, canning, and pickling, and a variety of do-it-yourself and craft projects. Based on qualitative research with 19 urban homesteading households with children in the Boston and Chicago Metropolitan areas, we argue that urban homesteading discourses and practices reflect and align with intensive mothering ideologies in the United States. Intensive mothering ideologies encourage a selfless devotion of physical, emotional, and mental energy to childrearing, and are often associated with individualized, privileged, and gendered subjectivities. We find these intensive mothering ideologies especially visible in the ways that mothers perceive and respond to environmental risk by adopting and enacting urban homesteading labors. We also note that the choice to respond to risk by homesteading is often, but not always, mediated and animated by economic, temporal, and social privilege. In this way, urban homesteading and surrounding discourses may inadvertently raise the bar of ‘good’ motherhood in ways that demand more of women and marginalize or burden mothers with less resources and privilege. However, rather than dismiss homesteading entirely on these grounds, we suggest that it may be possible to harvest impulses of care, connection, and collectivity associated with homesteading in ways that benefit rather than burden all mothers.  相似文献

The Internet is growing in popularity as a research site and is often framed as the next frontier in human subjects research. The opportunities the Internet provides for political organizing, making personal experiences more public, and creating spaces for a variety of voices makes it particularly relevant to feminist geographers and researchers such as ourselves. However, many qualitative researchers approach online research as though the Internet simply archives an abundance of data that is ‘there for the taking.’ Being trained in feminist research methods, we took issue with this approach, yet also encountered challenges when trying to apply feminist practices and ethical perspectives to online research environments. We explore these challenges through a collaborative reflection on our own independent online research experiences. Three themes emerge: (1) interpreting politics and visibility in online spaces, (2) researcher positionality across virtual and material study sites, and (3) subjectivity and power in online research ethics. Reflecting on these themes, we argue that the insights of feminist ethics and a feminist geographical lens are crucial for bringing much-needed reflexivity and reciprocity into online research. Simultaneously, online research opens up exciting new ways of conceptualizing central ideas within feminist research ethics, including politicization, positionality, and power.  相似文献
