Whose Land? Land Tenure in Late Nineteenth- and Early Twentieth-Century Palestine
The present article aims to uncover the different meanings attached to land ownership in Palestine during the late Ottoman and British Mandate eras and to show how a ‘modern’ understanding of ownership was imposed on the local population, particularly the fellahin (peasants), without a consideration of their needs and traditions. Many widespread claims are challenged, first and foremost the one according to which, at the time of the partition of Palestine (1947), ‘over 70 percent’ of it did not ‘legally’ belong to the local Arab majority, but to the British Mandate power, an assumption that has had political, cultural and social ramifications that have lasted until the present day.
Israel Remains on the Right. The Historical Reasons Behind a Long-established Political Supremacy
As a result of the last Israeli elections 48 out of 120 members of the previous Knesset will not return for another term something hard to imagine in most democratic countries of the world. Despite this, the coming government will remain firmly on the right. This is explained by the fact that what is commonly considered the center is actually the right (at least with regard to the conflict). This paper analyses the historical conditions that favoured this longestablished political supremacy. It is argued that demographic, regional and Palestinian related factors are relevant aspects for a comprehensive understanding of the issue, but that only a deeper analysis that takes on board the way in which religion, security and international law have been (mis)used can provide a full-fledged explanation.
Effect of Calcium Glycerophosphate on Demineralization in an in vitro Biofilm Model
The aim was to investigate the anti-caries properties of calcium glycerophosphate (CaGP) using an in vitro bacterial flow cell model. Four flow cells, inoculated from a chemostat containing a seven-organism bacterial consortium, were pulsed with sucrose twice daily, to provide an acidic challenge and pH-cycling conditions. Blocks of enamel and dentine were mounted in each flow cell. In a study on the effect of CaGP concentration, CaGP was pulsed into three of the flow cells, at the same time as the sucrose, to give concentrations of 0.10, 0.25 and 0.50%. Water was pulsed into the fourth flow cell with the sucrose. Microradiography revealed a significant dose response of decreasing demineralization as CaGP concentration increased. Reductions at 0.25 and 0.5% were significant when compared to the control. A second study investigated the effect of timing of CaGP pulsing, relative to sucrose, on enamel and dentine demineralization. CaGP (flow cell concentration 0.2%), was pulsed 1 h before, during or 1 h after the sucrose pulse; a water control was employed. In enamel, pulsing CaGP before the sucrose reduced demineralization significantly compared to concurrent pulsing, which in turn gave a significant reduction compared to pulsing after sucrose, which did not reduce demineralization significantly compared to the water control. In dentine, CaGP reduced demineralization significantly only when pulsed before the sucrose. The findings suggest that in vivo, the anti-caries potential of CaGP may be greater if it is applied before a cariogenic challenge.
