Agricultural research in marginal dry areas can contribute to reducing poverty through the development of technological, institutional and policy options for poor farmers. Such research should address diversified opportunities and development pathways. This article analyses the diversity of livelihood strategies of rural people living in the Khanasser Valley in northwestern Syria, an area that is typical of marginal drylands. It proposes an operational classification of households based on their different livelihood strategies, applying an integrated methodology within a Sustainable Livelihoods framework. Households are classified into three clusters: agriculturists, labourers and pastoralists. The article examines the diversity of livelihoods involved, and considers where and how research should be directed to have greatest impact on poverty. Given that rural households are not homogeneous but dynamic entities, with diverse assets, capabilities and opportunities, the definition of household typologies can help to target development research. The article concludes that while agriculturists benefit most, poor labourers with enough land can also gain from pro‐poor agricultural research. The poorest households with little land, and pastoralists, benefit little or only indirectly. 相似文献

The cruise ship is as much a process as an object. Indeed, while the ship appears stable in its material and affective form, this state is maintained only through the interventions of a vast array of human and non-human agencies. The cascading affects flowing from these interactions allow for alternative sociomaterial orders to be established through the suspension and splintering of fixed notions of time and space. This paper brings the theories of heterotopia and assemblage together, through a speculative realist ontology, to explore these temporal and spatial discontinuities, and the way they can create a sense of enclosure amongst passengers on-board. This theoretical approach is utilized to examine articulations of the cruise ship in the self-solicited blog entries of passengers that demonstrate both the mutable and emergent qualities of the ship and the way in which its seeming enclosure is subject to constant disruption. Rather than a static reading of the ship as a heterotopic ‘other space’, we propose that these spatial configurations are vulnerable to entropic forces and unruly agencies that frame the cruise ship as an emerging, rather than realized object, affording it the potential to enact alternative sociomaterial orders. 相似文献

An osteometric scoring technique is developed for the quantification of rickets deformational effects persisting in the healed adult skeleton. Termed RR-15 scoring (for residual rickets estimate, based on 15 main diagnostic osteometric traits), the method is first validated for sunshine deficit, and is then tested in a comparison of three climatically distinct archaeological populations from southeastern England. Two well-dated cemetery series were sampled: the Saint Bride's Church columbarium collection (SBC) from London at the time of the Industrial Revolution, for which the sex, age, and calender year at death of each individual are known; and the early Anglo-Saxons from Abingdon, near Oxford (AAS). Estimates of insolation in the past were developed indirectly by reference to δ18O mass spectrometer analyses of dated layers of the Greenland ice sheet. In SBC and AAS, the RR-15 score varies primarily as a direct function of computed sunshine deficit, but is also incremented by deficits of bioavailable calcium in their reconstructed diets, and by demographic stress in AAS, the inferred result of a high birth rate. The amounts of interglobular dentine present in the permanent first and third molar crowns of SBC and AAS have been shown to correlate similarly with sunshine and calcium deficits. The relatively high RR-15 score obtained in a small sample of northwestern European neanderthals lends quantitative support to the bioenvironmental hypothesis that sunshine-deficit rickets accounts for much of their paranormal gross morphology. 相似文献
