This paper provides a synthesis of the currently known evidence for cross-hatch patterning on stone, ochre and ostrich eggshell from Middle Stone Age Africa, between 100,000 and 60,000?BP. The significance of the incised artefacts is that they are used as proxies for an early capacity for symbolic thought, and potentially the emergence of language to convey their meaning. Beyond their significance in theoretical debates, these marked objects demonstrate conjunctions in the expression of design, exhibiting vertical, horizontal and oblique incised or engraved lines, patterns that have been classified as cross-hatching. Yet very little attention has been paid to the patterns themselves. This paper examines the archaeological evidence and looks at why these patterns might be important from a perceptual perspective. Taking a neurological approach, it considers current knowledge of neural, and especially visual, plasticity and the interconnectedness of brain areas relating to vision, learning, memory and emotion.  相似文献

The topic of physical disability has long been neglected in the field of geography. Geographers have challenged this neglect by undertaking studies of, for, and by persons with disabilities. This paper extends that challenge by examining the roles that disability and persons with disabilities play within the field of geography itself. The recognition and integration of persons with disabilities includes concerns with physical access, but also requires an examination of the institutional means by which geography departments, publications and conferences have worked and can work to challenge ableism: the neglect of disabled people's lives and perspectives. After centuries of exclusion, the recognition and integration of disability into society will surely be an issue of profound importance in coming years. We need geographers prepared and willing to study these processes.  相似文献

Reflecting on a recently completed ethnographic research project, I try to understand how things that may seem marginal to my central question nonetheless remain active within my arguments in unanticipated ways. I begin with an overview of my original research aims and activities before presenting eight marginal examples from fieldwork. I conclude with a meditation on the epistemic force that the marginal must be understood to exert on projects of knowledge production.  相似文献

One overlooked feature of Andrea's arrival in Barcelona at the beginning of Nada is the old and battered suitcase that she drags with her to her relatives’ apartment. It is filled almost entirely with books, books that—we may assume—she has read and plans to read again. Reading, it is clear, has played a large part in her intellectual and psychological formation as a teenager, but one of the strands of her overall maturation process during the forthcoming year will involve achieving a greater understanding of the distortions involved in how people (including her) see life through the optic of literature and literature through the optic of life. Gradually disabused of her overly literary adolescent imaginings, then, she eventually becomes a writer—of the text that is Nada—who is well aware of the traps that reading and writing hold.  相似文献

While it has been argued that conventional methodological resources are incapable of effectively representing ‘everyday social practice’ (see Latham 2003 Latham, A. 2003. Research, performance, and doing human geography: Some reflections on the diary-photograph, diary-interview method. Environment and Planning A, 35: 19932017. [Crossref], [Web of Science ®] [Google Scholar], Environment and Planning A, 35, 1993), this paper posits that a consideration of the ‘where’ of methodology can go some way to taking social practices seriously. Drawing on research into young people's spatial practices, conventional interview techniques were adopted in a range of different sites: a classroom, a school store-cupboard, and in teenage ‘hang outs’. Through discussion of these emplaced techniques, the paper demonstrates the difference the where of method makes to research. It will argue that, if harnessed appropriately, emplaced methodology can enhance social science's capacity to access the range of intelligences that constitute everyday social practice.  相似文献

ABSTRACT This paper considers a two‐community model with free mobility, public expenditures set by majority voting, amenities that differ across communities, and two types of taxpayers sorting across communities according to different preferences. Residents pay local taxes, consume public services, and have the right to vote. Vacationers cannot vote, yet pay local taxes, and consume amenities. Amenities attract vacationers whose tax payments produce rents reducing the costs of public spending for permanent residents. These extractable rents produce stability in otherwise unstable equilibria. Relatively wealthy communities are generally less able than poor communities to extract rents.  相似文献

Two juvenile skeletons excavated from medieval Norwich each have a well‐defined cystic cavitation. One involves the distal femur and the other the proximal tibia. The dry bone and radiographic appearance, as well as the location and age of the individuals, support a diagnosis of metaphyseal cortical defects. Although well‐known in clinical practice, especially in children, this appears to be the first published evidence for the condition in British archaeological material. No other anomalies were detected on the two skeletons. However, the occurrence of two cases in the same cemetery raises the possibility of a genetic influence in the condition.
