Phylogeographic analysis of barley DNA as evidence for the spread of Neolithic agriculture through Europe

Results of analyses of the photoperiod response gene (PPD-H1) and simple sequence repeats (SSRs) in modern landraces of cultivated barley were used as evidence for the mechanism of agricultural spread in Neolithic Europe. In particular, we explored the usefulness of considering adaptive genes as indicators of past selective pressures acting on crops, during their spread through Europe. In some areas, such as the Alpine region, Britain and Scandinavia, we have evidence to suggest that the adaptation of crops to certain climatic conditions may have contributed to the timing of agricultural spread. At the northern fringes of Europe, and in higher altitude locations in central Europe, the introduction of more suitably adapted cereals may have facilitated successful agriculture to trigger agricultural expansion. This research opens up the possibility of investigating other genetic adaptations to climate, which would permit a fuller evaluation of the relative contributions of climate/crop and forager/farmer interactions in the process of agricultural spread.     

Ancient DNA typing shows that a Bronze Age mummy is a composite of different skeletons

Excavations at Cladh Hallan, a Bronze Age-Iron Age settlement on South Uist in the Outer Hebrides off the west coast of Scotland, revealed the skeletons of two adults, a sub-adult and a child buried beneath the foundations of three roundhouses. Osteological and isotopic evidence has shown that the male adult skeleton is a composite made up of parts of at least three different individuals. To test the hypothesis that the female skeleton was also a composite we examined ancient DNA from four of its components: the skull, mandible, right humerus and right femur. Seven polymerase chain reactions (PCRs) were attempted, these covering positions 15,996–16,420, 16–132 and 232–368 of the mitochondrial DNA hypervariable I and II regions. Three PCRs were successful for each sample and a total of 55 sequences were obtained from the cloned products. After exclusion of possible contaminating sequences, the remaining 34 were compared. It was concluded that the mandible, humerus and femur come from different individuals. Insufficient data were obtained to draw conclusions regarding the origin of the skull. The presence of two composite skeletons at Cladh Hallan indicates that the merging of identities may have been a deliberate act, perhaps designed to amalgamate different ancestries into a single lineage.

CASH TRANSFERS AND POVERTY REDUCTION IN CHILE*

ABSTRACT The headcount ratio in Chile has declined from 40 percent to 14 percent since 1987. However, most analysis of this reduction uses national and regional poverty statistics. In contrast, we employ poverty mapping methodologies to find heterogeneity in the effectiveness of transfers across counties. To better understand this variation, we explore the roles of characteristics of the local population, structural features of the county, and geography. The greatest reductions in poverty occur in rural households, yet population characteristics and geography are also important. These findings suggest that targeting at low levels of aggregation can deliver further reductions in poverty.     

Towards an understanding of local protest: hospital closure and community resistance

The aim of this paper is to suggest an analytical framework through which the complex question of hospital closure and local protest can be further explored. The significance of this area of study lies with the extraordinary events that surrounded a campaign to save the Kidderminster General Hospital from downsizing. Whilst the hospital was not saved, the local campaign committee organizing the protest took their fight into the political arena and were successful in gaining a parliamentary voice in the 2001 general elections. Such an achievement has had considerable political implications, however, the question asked here is how might we begin to interpret the events that took place. To this end, the paper draws on current geographical literature in an attempt to construct a framework that accounts for both national policy debates and the local context within which such campaigns emerge.
