As human milk is exceptionally low in strontium-calcium () ratios, but solid foods are relatively high, it should be possible to examine the pattern of dietary supplementation and the age of weaning in prehistoric groups by reference to the ratios of juvenile skeletons. The data are presented that support this rationale, along with an investigation of the Sr/Ca values of juvenile and adult skeletons from a medieval Arab graveyard. The data from these skeletons are shown to coincide with the age-curves expected in theory, suggesting that new palaeodemographic information is indeed obtainable from studies. However, until further research is conducted, the technique provides a functional estimate of weaning patterns that is only suitable for comparative purposes. Additional research should clarify the relationship of functional to actual estimates of dietary supplementation and weaning. 相似文献

ABSTRACTChildren’s school transport has become a major research focus over the past 20 years, particularly within the fields of planning, transport geography, and children’s geographies. However, this work has rarely considered children living with disability. This article presents the pilot component of a visual ethnographic study about school transport within families living with childhood disability. It explains why we piloted the study, details the pilot process, and presents lessons learned from piloting the study with two families of children living with different mobility needs. The lessons largely concern the design of interview guides and the interviewing process, as well as the development of an adaptive photo kit to enable children’s independent participation. The article shows how piloting qualitative studies, particularly those involving disabled children, can be invaluable in terms of improving data collection technologies and logistics, as well as enabling inclusive participation. 相似文献

ABSTRACTAcross a number of disciplines at the University of Aberdeen, there is a long tradition of research focused upon the interrogation of issues associated with rural places and rural communities. Since the mid-1960s, rural geographical research has been a prominent component of the research undertaken by academic staff in Geography. Drawing upon an analysis of the large corpus of ‘rural’ publications arising from this scholarly enterprise, this paper presents a chronologically structured overview of how rural geographical research at Aberdeen has reflected developments in, and contributed to, the evolution of the sub-discipline of rural geography. 相似文献
