Although idealizations of motherhood are ever in flux, specific historical moments can be said to produce distinctive tropes of ‘good’ motherhood that have very real impacts on how women act and conceptualize themselves as mothers. This article examines good motherhood in its current iteration, and how now-common beliefs about breastfeeding are implicated in its construction. Furthermore, it looks at the ways in which idealizations of motherhood discipline the breastfeeding body so that it will fit into public space without disruption. I discuss the contradictory impacts of characterizations of the good mother as they appeared in the pro-breastfeeding dialogs that arose following a 2007 incident in which a mother was asked to cover herself up while nursing in a Kentucky restaurant. I posit that while these characterizations helped to make breastfeeding a more widely accepted public activity, they also had the effect of reifying a very narrow conception of what it means to be a good mother. I make this claim through an analysis of two common refrains heard in pro-public-breastfeeding arguments: breast milk is exceedingly healthy and mothers should not be persecuted if they nurse discreetly. Although these assertions together are compelling to the general public in that they provide a scientific justification for breastfeeding while at once assuaging fears of discomfort presented by a reproductive act being performed in a public space, I suggest that they also work to discipline women and maintain public-space-as-usual.  相似文献

Remains of the 16th-century Yarmouth Roads wreck, buried in sediments, were imaged using high-resolution geophysical techniques. The remains appear as strong reflectors underlain by an acoustic blanking zone, which was used to create maps of the wreck material. Close survey line-spacing allowed the construction of contour maps and hull sections, which revealed that the bow and stern sections are tilted to port at different angles, implying that they are detached. The seismic data have enhanced our understanding of the site beyond what was known from conventional archaeological investigations and confirms that this wreck was once a large carrack.

The presence of many phytolith-rich layers in late Bronze and Iron Age deposits at Tel Dor, Israel, are indicative of specific locations where plants were concentrated. Detailed studies of six of these phytolith-rich layers and associated sediments from Tel Dor show that the phytoliths were derived mainly from wild and domestic grasses. The most common domestic grass was the cereal Triticum aestivum (bread wheat). Three of these layers have a microlaminated microstructure, associated dung spherulites and phosphate nodules; characteristics that all point to the phytolith-rich layers having formed from dung in animal enclosures. In two of the layers, the microlaminated structure is absent while dung spherulites and phosphate nodules are present, suggesting that these too originate from dung that was not deposited in an enclosure. The sixth layer is microlaminated but does not contain spherulites. We thus cannot suggest a parsimonious explanation of its observed properties. Concentrations of burnt phytoliths are present in three locations, implying that dung was either burnt in situ or the ashes from burnt dung were redeposited. The transformation of dung accumulations into phytolith-rich layers involves a loss of organic material and hence a significant reduction in sediment volume, which is clearly apparent in the stratigraphy of some of the locations examined. The volume reduction can be observed in the macrostratigraphy and has important implications with regard to macrostratigraphic interpretation. The presence of abundant phytolith-rich layers on the tell has significant implications for the concept of ‘urbanism’ during these periods.  相似文献
