Why economics needs to be distinguished from physics,and why economists need to talk to physicists: a response to Foster and Holleman

Foster and Holleman argue that the systems ecologist H.T. Odum offered a valid theoretical framework for conceptualizing ecologically unequal exchange, and demonstrate its affinity with the Marxian theory of unequal exchange of embodied labour. However, both approaches suffer from the same fundamental confusion of the biophysical and the economic. The affinity between labour and energy theories of the unequal exchange of value was demonstrated by S.C. Lonergan already in 1988, but to thus define asymmetric transfers of biophysical resources in terms of underpaid ‘use values’ is misleading. Foster's recent endorsement of Odum is inconsistent with his earlier rejection of Odum's intellectual ancestor S. Podolinsky. While the ambition to ecologize Marx is laudable, it is in the interests of correct historiography and contemporary environmental justice activism to untangle some of the analytical problems in Foster and Holleman's article. A major problem is their failure to acknowledge the implications of N. Georgescu-Roegen's conceptualization of the relation between economics and thermodynamics.

Intersectoral efficiency between agriculture and industry in six C.M.E.A. countries: Introducing a simple equilibrium model

The purposes of this paper is to show how the long-run preferences for industry and agriculture of the planning bodies in six C.M.E.A. countries can be analyzed by using data on factor allocations in these sectors. Indicative results describing these preferences are obtained and existing inefficiencies in labor allocation and the relative domestic prices of industrial and agricultural goods are discussed. The conclusions suggest that the preferences of the planning bodies have stayed completely constant over 1950–1980 only in the case of the GDR, and that allocations of labor and domestic price ratios have mostly been far from optimal over that period in the countries that were analyzed.     

A case of sudden cardiac death in connection with Salmonella typhimurium infection

A case of fatal myocarditis in a 24-year-old otherwise healthy man is described. It was possible to cultivate Salmonella typhimurium from the alimentary tract, the blood, the liver and skeletal muscles. The possibility of a solitary myocarditis with fatal outcome due to Salmonella typhimurium infection is discussed. Such a case seems not to have been mentioned previously in the literature.The problems concerning the statistical registration of such a death are briefly discussed.

Measures for mines: approaches to impact assessment in humanitarian mine action

The ability to assess the impact of humanitarian interventions is key both for priority-setting and for maximising the quality of projects. Humanitarian mine action (hma) is a young sector, where the application of impact assessment is still in its infancy. In this article we will briefly revisit the history of impact assessment in hma, before reviewing the strengths and weaknesses of three different impact-assessment approaches: 1) the Landmine Impact Survey; 2) economic analysis; and 3) community studies. Each of the approaches has its own merits as well as its own shortcomings and the selection of one approach, or several approaches combined, needs to be informed by the particular conditions in a given setting. We argue that hma should always be based on sound impact-assessment practices, but also that it is important to encourage a general understanding of broader impact issues—as opposed to narrow output definitions—among all relevant stakeholders. In spite of considerable progress over the past few years on this issue, impact in mine action is still largely perceived as an event rather than an integral part of the process and specialised units responsible for impact assessment isolate this activity from day-to-day field management.
