Crossing spatial analyses and livestock economics to understand deforestation processes in the Brazilian Amazon: the case of São Félix do Xingú in South Pará

The Amazon is the largest tropical forest area on Earth, and has been undergoing rapid deforestation for the last four decades. In the Brazilian Amazon, large‐scale pasture for cattle ranching and soybean production are the main land uses, leading to a yearly deforestation rate of 0.5%. These conversions are mostly located in frontier areas distributed along the so‐called “arc of deforestation”. Within this large zone, various land use change processes are interacting through several modes of land valuation and organisation. From several case studies in the State of Pará (Brazil), the current project aims at analysing how landscape dynamics are related to infrastructure development, ecological conditions, zoning policies and to the evolution and the organisation of the production, consumption and marketing chains of livestock products. This paper presents the results for one test site, the region of São Félix do Xingú, South of Pará This region is the focus of land speculation, cattle expansion, and deforestation. Road construction, investments in electrical energy, financial credit for cattle, and the land reform policies have all fuelled this process. All these factors make this region one of the most dynamic agricultural frontiers in the Brazilian Amazon. The main objective of the paper is to improve our understanding of deforestation processes by crossing spatial analyses and 1ivestock economics.studies, and to characterise the role and impact of various natural and anthropic factors in the location and development of the main types of farmers, and their policy implications.     

Computing equilibria of GEI by relocalization on a Grassmann manifold

An algorithm is described to compute equilibria of the general economic model with incomplete asset markets, that is, of GEI. The algorithm is based on the existence of a route of zeros of a homotopy whose domain includes the price simplex and a Grassmann Manifold. This route is followed, in effect, by localizing and following diffeomorphic pieces in Euclidean space, and by relocalizing as is necessary.     

Buildings for the Japanese information economy : Neighbourhood and resort offices

A new physical infrastructure to support activities based on communications and the transmission of information is being developed. Part of this infrastructure includes the construction of ‘intelligent’ buildings which are seen to play as important a role in improving efficiency of office workers as automation has played on the shopfloor of manufacturing industry. The location of these buildings is important. This article focuses on two types of experimental office development—neighbourhood offices and resort offices.     

Corporate Social Performance, Stakeholder Orientation, and Organizational Moral Development

This article begins with an explanation of how moral development for organizations has parallels to Kohlberg's categorization of the levels of individual moral development. Then the levels of organizational moral development are integrated into the literature on corporate social performance by relating them to different stakeholder orientations. Finally, the authors propose a model of organizational moral development that emphasizes the role of top management in creating organizational processes that shape the organizational and institutional components of corporate social performance. This article represents one approach to linking the distinct streams of business ethics and business-and-society research into a more complete understanding of how managers and firms address complex ethical and social issues.
