This article introduces a new approach to measure corporate contributions to sustainability called Sustainable Value Added. Existing approaches to measure sustainability are based on a comparative assessment of environmental and social burdens and can thus be characterised as burden-based approaches. However, these approaches suffer from severe limitations as a comparative assessment and aggregation of all relevant environmental and social burdens fails in practice. In contrast to these burden-based approaches Sustainable Value Added is value-based. It determines the value that is created by the reduced or increased use of different environmental and social resources. For this purpose the use of environmental and social resources is valued at their opportunity cost. Sustainable Value Added allows an integrated assessment of the economic, environmental, and social performance of a company and expresses the corporate contribution to sustainability in a single monetary indicator. This article explains the theoretical background of Sustainable Value Added, relates it to existing approaches to measure sustainability, and - using the example of Henkel KGaA - demonstrates its practical applicability.

With reference to the Kosovo war, we examined how the (un-)justness of military intervention is cognitively constructed. Four types of reinterpretation were hypothesized to relate to positive evaluation of the intervention: minimisation of negative consequences of NATO's intervention, denial of responsibility of the Western countries for the war, blame of Yugoslavia, and justification of the intervention through positive motives. As determinants of evaluation of the war, belief in a just world, militarism-pacifism, authoritarianism, and diffuse political support were taken into account. Hypotheses were tested with 165 university students using structural equation modelling. Consistent with our assumptions, the four types of reinterpretation related strongly to positive evaluation of the intervention, showing their relevance with regard to military intervention. Further, the assessed political attitudes influenced evaluation of the war while, contrary to predictions, belief in a just world did not. The causal status of the reinterpretations and the interplay of belief in a just world and political attitudes are discussed.

Based on the analysis model favored by the study of the conditions in which the seventeenth century Querelle des Anciens et des Modernes took place, we examine the case of confrontation between realism and abstraction, which occurred in the context of Spanish art in the nineties of the twentieth century. Connections are established with other aesthetic conflicts which are considered part of a genealogy whose most explicit antecedent could be placed in the before mentioned complaint, such as the confrontation between realism and abstraction in the American art scene, which occurred in the fifties of the last century, and the more recent controversy on pluralism and the end of art.
