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

Knowledge and science transfer – introductory remarks. The article presents introductory remarks on the historical study of knowledge and science transfer. Discussion focuses initially on the reasons for speaking of knowledge transfer and not only about science transfer, and the relations of this topic to current research in general history on cultural transfer. Multiple levels of knowledge / science transfer are then discussed, specifically: (1) transfer by means of migration or other movement of people across geographic boundaries; (2) scientific changes related to the transfer of objects (such as plant specimens or instruments) across continents or disciplines; (3) knowledge or science transfer in practical contexts. Addressed throughout is the problematic character of the concept of transfer itself. The author suggests that users of this concept often presuppose a static conception of scientific and cultural contents being more or less successfully transferred; more interesting, however, are the changes in science and culture conditioned or caused by the migration of individuals as well as the transfer of culture by other means.  相似文献

Professional visual artists have always enjoyed considerable latitude in the selection of a place of work and residence. Recent decades have witnessed their growing presence within the Canadian countryside. This paper seeks to provide an interpretation of this phenomenon by exploring two sub-objectives. First is to determine whether artists who establish themselves in rural communities can be considered to be part of the counter‐urbanisation movement, involving the relocation of urban residents down the settlement hierarchy. Second is to identify what types of migration are occurring and why. Our surveys of visual artists residing in the southern Ontario communities of Elora and Parry Sound reveal that most participants are part of a movement involving the decision to take up both residence and employment in a rural locale. We further find that the relocation of visual artists is driven to some extent by a strong attachment to natural landscapes. By way of conclusions, we briefly speculate about the broader population of urban residents. We remind ourselves that artists often have been harbingers of new movements and that today there are growing numbers of workers outside the artistic community who also have increasing latitude in regards to choosing where to live and work. Overall, our findings suggest that there is ongoing blurring of geographic boundaries—between space and place, between place of work and place of residence and, of course, between rural and urban.  相似文献

Dislocation is the most severe form of developmental dysplasia of the hip (DDH). It significantly impairs hip function in the young, and may lead to debilitating early‐onset osteoarthritis in adults. To our knowledge no thorough study of a large skeletal population has ever been undertaken to determine the wide range of diagnostic criteria for this condition in pathological specimens. To identify these criteria we have analysed the cases of developmental dislocation from a large series of 6000 individuals (6580 hips) from the medieval cemetery at Spitalfields in London, UK. We describe the changes at the true acetabulum, and have created a four‐stage classification of the false acetabulum. The skeletal response to the altered biomechanics and limb shortening that occurs in developmental dislocation is described in the pelvis, lower limb and spine. This includes asymmetric growth in childhood, and asymmetric degenerative change in adulthood. We conclude with a discussion of the clinical literature on developmental dislocation of the hip that will aid palaeopathologists to estimate the symptoms that an excavated individual may have experienced during their lifetime.

Dysentery was a significant cause of ill health during medieval times according to written sources of the period. However, it has been very difficult to detect the organisms that cause dysentery in archaeological samples from latrines and cesspools. This is because the cysts of the enteric parasites that cause dysentery are very small and usually fragment in the soil, in contrast to the robust ova of parasitic intestinal worms. This study uses a monoclonal enzyme-linked immunosorbent assay (ELISA) technique to identify the fragments of those enteric parasites that cause diarrhoea. Samples were taken from two excavated medieval latrines in the city of Acre. Coins and radiocarbon dating suggest that the latrines were in use during the thirteenth century CE. Positive results were noted for Entamoeba histolytica and Giardia duodenalis, while Cryptosporidium parvum was negative. This is the first time that either of these parasites have been identified in the Middle East using these methods.  相似文献
