Abstract

Although there is evidence that some populations of large whales in the Southern Hemisphere have increased in recent years, differences in feeding behaviour and migration patterns largely precludes direct competition between these and coastal and pelagic fisheries in the South Pacific Ocean. In particular, many of the whales that spend at least part of their year in the South Pacific make feeding migrations in summer to Antarctic waters where some estimates put their food intake at 90% of annual consumption. Others, such as female sperm whales (Physeter macrocephalus), which do not migrate from tropical/subtropical South Pacific waters, feed at depths greater than that usually occupied by species that are the targets of commercial fisheries, such as the tunas (Thunmisspp.). Thus, even though consumption by whales is high, dietary overlap with commercially fished species is relatively low as much of their feeding is in waters that are not exploited by fisheries. However, there are a number of anecdotal reports that some smaller cetacean species, in particular killer and pilot whales, take fish from longlines set in the region, although more are lost to sharks. However, it should be noted that any assessment of interactions between whales and fisheries is limited by a lack of qualitative and quantitative data. Abundance estimates, particularly for some of the smaller species in the South Pacific region, are only order of magnitude estimates. Furthermore, knowledge of food chains (and their interactions) for many cetaceans in the South Pacific is sketchy making assessment of their impact on local fisheries‐difficult.  相似文献

One of the most significant public risk management developments of the past 15 years has been the creation of local government risk control and risk financing pools. Today it is estimated that over 200 pools provide services for up to 20,000 local governments. This article is an introductory discussion of pooling and includes information drawn from the first nationwide survey of pools, and gives suggestions for future research.  相似文献

In this article we introduce a new scoring system for doing operational code analysis and test its reliability and validity by measuring and modeling President Jimmy Carter's operational code. Using speeches from the public record, we construct indices for the elements of the operational code construct. Based upon the valences and scaled intensities of verbs uttered in the speeches, President Jimmy Carter's views of the political universe and approaches to political action in different issue areas are identified and compared. The results of the analysis provide reasonable support for the face, construct, and content validity of the operational code indices. We find that Carter's view of the political universe and approach to political action were consistent across issue areas during the first three years of his term as president. Following the Soviet invasion of Afghanistan President Carter's support for human rights remained steadfast. Statistically significant shifts occurred in his views of the Soviet Union and others in the political universe and in his approach to political action regarding the conduct of U.S.-Soviet relations and other issues.  相似文献
