This paper examines the financial performance of the FTSE4Good indices; the indices include companies from different geographical areas on the basis of pre‐determined social responsibility criteria: currently environmental sustainability, relationships with stakeholders, attitudes to human rights, supply chain labour standards and the countering of bribery. The results indicate that over the period of analysis from 1996 to 2005 these indices outperformed their relevant benchmarks. However, most of this outperformance was due to risk differences between the FTSE4Good indices and their benchmarks. In addition, much of the outperformance arose in the period before the indices could be used by practitioners. Nevertheless, the results suggest that investors who invest in a portfolio of companies that satisfy FTSE4Good's corporate social responsibility criteria do no worse than their counterparts who do not follow a socially responsible strategy when purchasing equities.

Evaluating the consequences and future of land protection requires broad temporal and spatial perspectives of ecological and cultural factors. We assessed the development of a system of protected areas comprising 37% of central Massachusetts in terms of changing rates and means of land protection. We compared protected areas to the surrounding matrix in terms of physical, biological, and historical features and used these results to raise issues concerning future planning. The rate, purpose, and means of land protection in the North Quabbin Region (168,312 ha) have been dynamic as a result of changes in cultural values and transformation of the landscape from predominantly agriculture to forest. Protected lands are managed by 25 federal and state agencies, private groups, and municipal departments and commissions and are physically and biologically typical of the regional landscape which results from (1) participation of diverse organizations with varied agendas; (2) predominance of large government acquisitions driven by landscape-scale criteria; and (3) absence of coordination among groups. The large area, relative homogeneity and largely undeveloped status of the North Quabbin Region suggest conservation goals distinct from those in the fragmented and extensively developed neighboring areas of the Connecticut River Valley and Cape Cod and Islands Region. Large tracts of forests, wetlands, and lakes in the North Quabbin Region provide (1) habitat for species requiring extensive, intact areas; (2) the opportunity to maintain broad-scale ecological processes; (3) connections to regional conservation areas; and (4) recreation. To realize the area's potential, a comprehensive plan must be based on a broad-scale perspective and historical understanding of the landscape.  相似文献

Much effort has been directed toward elucidating pollution effects on marine benthic communities (Pearson and Rosenberg, 1978; Sanders et al., 1980; NAS 1985). Less effort has been directed at methods of data analysis which will identify distribution patterns and relationships between communities. Traditional community structure summary parameters such as species richness and various indices of diversity utilize only part of the information contained in a data set and are not very useful in elucidating relationships between communities of animals.  相似文献
