Landscapes in southern Australia have been extensively modified by a variety of human activities, predominantly agriculture and urban development. Over much of the area, native vegetation has been replaced with agriculture or buildings and infrastructure. A continuum exists from areas that remain largely intact, but are modified in some way (e.g. forests managed for timber production), to areas where the remaining native vegetation is fragmented to varying degrees. Habitat management will vary across this continuum, depending on the degree of habitat loss and isolation. In areas outside the main zones of agricultural and urban development, the process of habitat loss and fragmentation is less in evidence. Here, instead, the landscapes remain apparently structurally intact, in that the native vegetation is not actually removed. However, these landscapes have also, in many cases, been significantly modified, particularly by pastoralism and related activities, to the extent that their value as habitat is impaired. Declining habitat value in northern landscapes may lead to the same types of functional fragmentation as found in the south. An examination of the differences and similarities between southern and northern landscapes can highlight what can be learned from the southern experience which may be of value in savanna landscapes. In both cases, the importance of considering impacts in relation to species-specific responses needs to be emphasised.

Richard Hobbs examines one of society's greatest problems: the need for reconciliation between the democratic dislike of war and the appropriate use of the military instrument in world politics. He questions whether the results obtained in war are worth the expenditures made and contends that victory gained from total war--war pushed to its outer li

We present a model of CSR as a set of mechanisms for aligning corporate behaviour with the interests of society in reducing externalities and promoting a sustainable corporate sector. These mechanisms include voluntary action by companies to go above minimum legal standards, with the aim of enhancing competitiveness ("action beyond compliance"); interventions by regulators designed to promote self‐regulation by industry ("reflexive law"); and steps taken by shareholders to put pressure on companies to make effective use of corporate assets ("shareholder engagement"). We then assess the degree to which the model is realised in current British practice. Focusing on the issue of working conditions, we find managerial resistance to the linking of CSR with internal employee relations, and obstacles to shareholder engagement on this issue.

Prevailing patterns of dispersed share ownership and rules of corporate governance for UK listed companies appear to constrain the ability of managers to make credible, long‐term commitments to employees of the kind needed to foster effective labour‐management partnerships. We present case study evidence which suggests that such partnerships can nevertheless emerge where product market conditions and the regulatory environment favour a stakeholder orientation. Proactive and mature partnerships may also be sustained where the board takes a strategic approach to mediating between the claims of different stakeholder groups, institutional investors are prepared to take a long‐term view of their holdings, and strong and independent trade unions are in a position to facilitate organisational change.
