UNITED STATES ENERGY PROJECTIONS AND OPTIONS

Evaluation of energy options and adoption of appropriate policies require rigorous demand and supply projections. The wider the options, the more difficult the task. The author reviews the various projections which have been made in the United States to support a policy toward energy independence. He sets the stage for a similar review of the 1977 National Energy Outlook, scheduled for publication early in the year, in a subsequent issue of the Forum.     

Bridging the gap between romantic relationships and sexual harassment in organizations

Workplace romances and sexual harassment are pervasive in today's organizations. However, despite the fact that these two phenomena share a social-sexual component, they have primarily been treated as unrelated organizational issues. We advance an affective link between workplace romances and sexual harassment. Based on this theoretical connection, we discuss conditions under which workplace romances may result in sexual harassment. Finally, we address managerial implications of the romance–harassment link. © 1997 John Wiley & Sons, Ltd.     

Use of Fatty Acid Analysis to Determine Dispersal of Caspian Terns in the Columbia River Basin,U.S.A.

Abstract: Lethal control, which has been used to reduce local abundances of animals in conflict with humans or with endangered species, may not achieve management goals if animal movement is not considered. In populations with emigration and immigration, lethal control may induce compensatory immigration, if the source of attraction remains unchanged. Within the Columbia River Basin (Washington, U.S.A.), avian predators forage at dams because dams tend to reduce rates of emigration of juvenile salmonids (Oncorhynchus spp.), artificially concentrating these prey. We used differences in fatty acid profiles between Caspian Terns (Hydroprogne caspia) at coastal and inland breeding colonies and terns culled by a lethal control program at a mid‐Columbia River dam to infer dispersal patterns. We modeled the rate of loss of fatty acid biomarkers, which are fatty acids that can be traced to a single prey species or groups of species, to infer whether and when terns foraging at dams had emigrated from the coast. Nonmetric multidimensional scaling showed that coastal terns had high levels of C₂₀ and C₂₂ monounsaturated fatty acids, whereas fatty acids of inland breeders were high in C18:3n3, C20:4n6, and C22:5n3. Models of the rate of loss of fatty acid showed that approximately 60% of the terns collected at Rock Island Dam were unlikely to have bred successfully at local (inland) sites, suggesting that terns foraging at dams come from an extensive area. Fatty acid biomarkers may provide accurate information about patterns of dispersal in animal populations and may be extremely valuable in cases where populations differ demonstrably in prey base.
