A trial, monitored release on the Wingecarribee River over 27 days had a peak discharge below the Wingecarribee Dam of 1090 ML/d, which had a flow duration of 0.95 per cent. Morphological impacts on 29 km of channel below the dam included bank erosion, concentrated neck overflow, bed degradation and channel widening at recent cutoffs, sedimentation in weir pools and overbank flow, particularly at discharges greater than 800 ML/d. Prolonged operational releases at bankfull discharge (400–800 ML/d) will have the greatest morphologic impacts and should be avoided. Pulses which dissipate stream power over a broad, well-vegetated floodplain should be incorporated in the operational release policy, provided such pulses are phased to facilitate channel and vegetation recovery.  相似文献

This address is concerned with the lack of detailed understanding we have of rivers. It is argued that to manage river systems for environ- mental and ecological sustainability, there must be understanding of riverine biophysical processes. These are explored through a consideration of: (1) channel airspace and water; (2) the perimeter conditions of the channel as the boundary between erosional channel and depositional floodplain, both of which occupy the valley-floor trough; (3) ecological components of channels and (4) the human components where human interactions with catchment environments have such impacts on the biophysical systems. Finally, the implications of these four components for understanding the systems for more sustainable management are discussed.  相似文献

Few would have predicted in 1969 that the new Republican administration of Richard Nixon would initiate a rapprochement between the United States and communist China during his first term as president. That he succeeded in doing so was helped by the severity of the Sino‐Soviet dispute, which erupted into armed clashes in the spring and summer of 1969. By the end of 1970 China made it clear that it would not only be willing to receive a presidential envoy, but also the president himself. Two missions to Beijing by Nixon's national security adviser, Henry Kissinger—one secret in July 1971 and the other public in the following October—paved the way for a presidential visit in February 1972. The talks in July and October 1971 and February 1972 covered a whole range of issues including the war in Indochina, the potential threat from Japan and relations with the Soviet Union. The most dif cult problem, however, proved to be that of Taiwan, where the American‐backed Nationalist government not only laid claim to be the legitimate government of the whole of China, but occupied the Chinese seat in the United Nations. A modus vivendi was eventually reached in February 1972, helped perhaps by the United Nations General Assembly vote in October 1971 which unseated the Taiwan regime in favour of mainland China. The US negotiating position was not made any easier by the intense rivalry between Kissinger and the State Department and the latter's exclusion from much of the negotiation process led to a last‐minute crisis which threatened the success of the entire project. While neither the United States nor China achieved all that they had hoped, Nixon's visit to China had an enormous symbolic impact and contributed to a reconfiguration of the global balance of power.  相似文献

This article investigates attempts to portray Jesus as a “manly Man” for “manly men” in the wake of World War One. The Jesus that emerged as a result of this enterprise was a heroic personality formed through interplay between ideals about soldiers and Christ. Whilst only some military virtues were valued — and only in particular forms — even these proved problematic in certain respects. In particular, attempts to integrate soldierly and moral manliness, especially through resurgent use of notions like chivalry and crusade, failed to connect with soldiers’ actual experiences. Nonetheless, the manly Jesus represented an important religious response to World War One. It illuminated much about New Zealand religion and religious interaction with visions of ideal manhood. In particular, visions of a manly Jesus highlighted that ideals of moral and domestic manhood and more assertive ones coexisted in a state of tension.  相似文献

The role of private market agents in global monetary and financial governance has increased as globalization has proceeded. This shift in both markets and patterns of governance has often been encouraged by states themselves in pursuit of liberalization policies. Much of the literature views these developments in a positive light, yet there are other aspects of these developments that also merit attention. This article supports its central propositions with two cases of emerging global financial governance processes: the Basel II capital adequacy standards for international banking supervision and the International Organization of Securities Commissions‐based transnational regulatory processes underpinning the functioning of cross‐border securities markets. Based on the case findings, the article argues first that private sector self‐regulation and/or public‐private partnership in governance processes can leave public authorities vulnerable to dependence on the information and expertise provided by private agents in a fast‐moving market environment. Policy in the vital domain of financial regulation has been increasingly aligned to private sector preferences to a degree that should raise fears of bureaucratic capture. Second, the article contends that the overall outcome in terms of global financial system efficiency and stability has been mixed, bringing a range of important benefits but also instability and crisis for many societies to a degree that has led to challenges to global governance itself. The case material indicates that the input, output and accountability phases of legitimacy in global monetary and financial governance are highly problematic, and much of the problem relates to the way in which private market agents are integrated into the decision‐making process. Third, the article posits that a better consideration of these three ‘phases’ of legitimacy and their interrelationships is likely to enhance the political underpinnings and legitimacy of global financial and monetary order.  相似文献

The ministerial revolution of 1710 transformed a predominantly whig administration in April to a tory-dominated ministry by September. Historians have generally attributed this transformation to the political objectives and skills of Robert Harley. But such a conclusion makes the methodological error of deducing his intentions from the outcome. On close examination Harley did not intend to make such drastic changes initially. On the contrary, he wished to limit them to the removal of the earl of Sunderland from his secretaryship of state and the earl of Godolphin from the lord treasurership, and to curtail, if not eliminate, the influence of the duke of Marlborough and his duchess in affairs of state. Other whigs, especially the so-called junto, he hoped to retain in power. This would have necessitated the retention of the existing parliament which did not have to be dissolved under the Triennial Act until 1711. These plans came unstuck. The junto, though prepared to take Harley seriously, eventually refused to deal with him and resigned their offices. Harley was also obliged to take in more tories than he wanted. The main reason for the failure of his original plan was the influence of Queen Anne, which has been overlooked or underestimated in previous accounts.  相似文献

Interest in the battle of Pollentia in recent years has been confined to the issue of dating the year in which it occurred, the extent to which either Claudian or Prudentius, the two late Roman poets who mention it, depended on the other's work, and the significance of the battle in the political and military careers of its two chief protagonists, Stilicho, the Vandal regent of the emperor Honorius, and Alaric, the Visigothic leader and rebellious Roman agent. In this paper, I consider religion as a tactic in the conduct of the battle. We know from Orosius that it was fought at Easter, something for which he chastised Stilicho. While scholars refer to its Easter date and Vanderspoel has found Easter allusions in another of Claudian's poem written in the light of the battle, none has investigated the significance of the battle taking place at Easter. It is argued here that religious considerations were crucial in determining the moment of engagement and not just coincidental and that, by attacking Alaric at Easter, we have another indication of just how precarious Stilicho's position was.  相似文献
