British government policy in Africa under Labour has been motivated by a combination of humanitarianism and self-interest. The policy has been shaped principally by the Department for International Development (DFID), but also by the Foreign and Commonwealth Office (FCO) and by Prime Minister Tony Blair himself, as he has become more interested in Africa issues. The main focus of the policy has been on poverty reduction and development. The approach has been multi-dimensional, aiming to tackle the principal obstacles to development such as conflict, HIV, debt, governance and trade barriers. The UK has sought to increase its leverage in Africa by working multilaterally with its allies and through the UN, the World Bank and the EU. But the policy has been hampered by the inherent difficulty of promoting sound development policies in weak states, by a lack of UK leverage to affect change, and by a UK preference for statist solutions. Strategic and commercial objectives pursued by the FCO and the prime minister have sometimes appeared as being at odds with the developmental objectives of DFID. Post-9/11 concerns have reinforced the UK's motivation for dealing with Africa's problems, particularly the problems of weak and failed states. But western policies related to the war on terror may give rise to new contradictions and complicate the UK's developmental efforts in Africa. 相似文献

For many decades tephrochronology has been used as a scientific method for dating archaeological as well as geological remains in Iceland. Recently, parts of the tephrochronology for the eruptions of the famous volcano Hekla have been questioned by the author. This is due to obvious differences in dating results of archaeological artefacts from the valley of Thjórsárdalur in southern Iceland and the current tephrochronological dating of its devastation. While the devastation of the valley has been dated to AD 1104 and is thought to have been caused by a huge eruption of mount Hekla in that year, the artefacts from excavations and stray finds, as well as new 14C results, show somewhat later 12th‐13th century dates. The paper deals with this obvious discrepancy, which has hitherto been ignored, together with the results of archaeological excavations in 1983–86 at Stóng in Thjórsárdalur; it also gives a critical analysis of the historical methodology of the tephrochronologists. 相似文献

This article examines the complex and tangled relationships between home, city, and gender in Bagcilar, a municipality in Istanbul governed by Islamist-oriented political parties since 1992. Focusing on women’s spatial experiences at the intersection of the private and the public, the traditional and the modern, the secular and the religious, this article argues that home provides a medium through which gendered forms of governance and publicness are produced in the city. Home as a domestic sphere confines women’s roles to those of motherhood and wifehood, but also functions as a place of sociability for women. The municipality’s Islamic political discourse, combined with secular urban practices, mobilizes women through familial norms, gender-segregated events, and women-only sites in Bagcilar, where home and urban space are mutually constructed, regulated, and legitimized. Thus, women’s publicness, which derives from but goes beyond domesticity, also enables intimate same-sex sociality in urban spaces. Although this creates only conditional access to the city for women, their agency and engagement with the city emanate from such publicness. 相似文献

The effect of carbonic anhydrase enzyme on the precipitation kinetics and phase transformations of calcium carbonate, and on the strength development of lime mortars has been investigated with saturated lime solutions, lime pastes and lime mortars under atmospheric conditions. The results clearly show that carbonic anhydrase catalyzes the reaction between carbon dioxide and aqueous lime, and increases the rate of calcium carbonate crystallization, the yield of the carbonation reaction and mortar strength at early ages. This is most likely a kinetic effect associated with the increased rate of carbonate ions supply to the solution by the enzyme. In addition, this enzyme favors the formation of stable calcite and significantly modifies its morphology by developing new crystal faces. These results suggest a novel approach for accelerating the hardening of lime mortars using carbonic anhydrase enzyme, which may offer a potentially novel approach with significant benefits on the applications of lime mortars in architectural heritage conservation as well as in construction. 相似文献

Little research examines the stage of the policy process during which policy alternatives are formulated. Using quantitative and qualitative data from Swedish local politics, we address this deficiency by analyzing the process by which the number of specific policy alternatives is reduced. The findings suggest that, in approximately 20 percent of issues, more than one alternative will reach all politicians making the binding decisions. Most local politicians, in both the majority and opposition factions, think that they lack sufficient information on alternative policy designs. We also find a “political bias,” that is, alternatives are discarded at an early stage because they are deemed not politically feasible. Politicians outside the inner circles, especially those with higher education, would like to see more policy alternatives to discuss and from which they can make choices. 相似文献
