India's rise in Africa has been largely overlooked, despite the important implications of the growing presence of Indian corporations and a rise in New Delhi's political ties with the continent. Not only are Indian actors providing much‐needed investment and capital, but Indo‐African connections represent a further important diversification of Africa's international relations, something which reflects a major development for the continent. Indian activity in Africa may be said to constitute a middle ground between China's profit‐maximizing and largely statist approach and the much‐resented intrusive conditionalities associated with western policies. It is evident that India's growing activity in Africa has the potential to help African companies become more efficient by exposing them to competition, new advances in technology and modern labour skills. African governments could potentially use the opportunity of an increased Indian corporate presence in Africa as sources of appropriate technology, skills and advice for economic development. However, if not handled correctly, any goodwill that India possesses in Africa will quickly be squandered and/or India will become just another actor in Africa. It is up to Africans to negotiate with Indian actors to ensure that the benefits accrued from Indo‐African ties are evenly shared and that Indian interest in the continent, alongside that of others, may help to serve as a catalyst for economic revitalization. The key issue is how African leaders can seek to leverage newfound Indian investment and interest in Africa so that Africa's place in global trade networks becomes more proactive and beneficial to the continent's citizens.  相似文献

Globally, sea‐level rise is expected to impact on many coastal regions and settlements. While mitigation of global greenhouse gas emissions remains an important task, adaptation is now seen as a critical component of the policy equation. Local government is a key player in adaptation planning and managing risk through their mandated role in land use planning and development control. Yet, managing the predicted impacts of climate change is proving to be a complex and difficult task for planners and policy makers. This paper reports on a case of local government deliberation on possible planning responses to address future sea‐level rise impacts in New South Wales, Australia. Using structured, expert opinion of planners and other technical experts engaged in a collaborative network in the Sydney region, we explore the feasibility of implementing planning and policy measures at the local and regional scales to respond to inundation risk as a result of sea‐level rise and storm surge events. Our research shows how local governments employ specific scale‐oriented strategies to engage private and public actors at different scales to manage legal, financial, and technical risks in coastal adaptation.  相似文献

The Uncoupled Modal Response History Analysis (UMRHA) method developed by Chopra et al. is modified in this paper to estimate damage to welded moment-resisting connections in a steel frame (MRSF) subjected to earthquake ground motions. The behaviour of these connections is modelled by a moment-rotation relationship that accounts for the cracking of the beam flange-to-column flange groove weld. The behaviour of the frame is approximated by a sequence of single-degree-of-freedom (SDOF) models for the first three modes to allow for the contribution of higher modes of vibration. The dynamic properties of these SDOF systems are determined by nonlinear static pushover analyses of the building frame. Because of the significant drop in connection strength caused by beam-to-column weld cracking, the pushover procedure uses a changing rather than invariant distribution of horizontal loads, while the structural responses are calculated from shapes that are based on the displaced shape of the frame after damage occurs. The accuracy of the method is demonstrated by a comparison with the results of a nonlinear time history analysis of the frame. This method can be used for rapid assessment of seismic damage or damage potential and to identify buildings requiring more detailed investigation.  相似文献

Chancellor Gordon Brown has declared that 2005 will be a milestone in the United Kingdom's campaign to meet the UN Millennium Goals. Owing to Britain's chairmanship of both the G8 and the European Union in 2005, Brown believes that an opportunity to raise the continent's star in global politics presents itself. This comes after the launch in 2004 of the Blair Commission for Africa and a recent spate of high profile interventions by assorted politicians and famous musicians. It also follows a trend begun at the G8 meetings where Africa is placed on the G8 agenda. Such an interest in the continent is to be welcomed. Yet this article contends that Gordon Brown's assumptions regarding Africa's troubles, and the ingredients found within his proposals, are mistaken and need rethinking. The article argues that Brown's approach to Africa's problems is based on incomplete information or a misreading of the situation, and by default may serve to prolong Africa's crises rather than alleviate them.  相似文献

An intriguing feature of electoral systems is that apparently insignificant modifications of their constituent rules can have important consequences. One such potentially important change, following the increase in the size of the Senate in 1984, was the shift from five to six places for each state to be filled at each half Senate election. Attention has been drawn, most notably by Sharman \[1986. 'The Senate, Small Parties and the Balance of Power.' Politics 21(2): 20-3], to the capacity of this change to reduce the representation of small parties, with adverse consequences for the role of the Senate in national government. A decline in Labor's share of the vote and growth in support for minor parties are identified as the primary reasons why the predicted outcomes have not eventuated. The paper speculates about the possible future relevance of Sharman's argument.  相似文献
