Accounting for animal health in efficiency analysis: An application to Swedish dairy farms
American Journal of Agricultural Economics, EarlyView.Abstract Poor animal health is a central concern in modern livestock production. Despite the necessity to incorporate animal health in efficiency analysis, the theoretical and empirical developments are limited on this subject. This article appropriately characterizes the axiomatic properties of animal health within a production framework.

Electrochemical Control of Scholl Reaction: Arenium Cation Versus Radical Cation Pathways
Angewandte Chemie, EarlyView.Electrochemical control of Scholl reactions allows selective access to the arenium cation and radical cation pathways via low‐potential acidic (LPA) and high‐potential neutral (HPN) conditions, respectively. This control reveals that most substrates react through both pathways, albeit with clear preferences, and provides an experimental foundation for ...

, 1994 Cet article essaie de montrer en quoi la conception néoclassique de la rationalité est inadaptée pour traiter les problèmes de décision en avenir incertain. Pour des raisons pratiques mais surtout logiques la théorie traditionnelle de la décision ne peut

American Journal of Agricultural Economics, EarlyView.Abstract Discrete choice experiments are increasingly being used to estimate land managers' willingness to accept participation in incentive‐based environmental programs. This is a specific application of discrete choice experiments: the estimation of willingness to accept for a private good (program participation) where respondents have to make trade ...

Double Reduction of Ph3B to a Dianionic Borane With a Powerful SrI Intermediate
Angewandte Chemie, EarlyView.Although dianionic boranes follow the octet rule and are isoelectronic to carbanions or amines, the high electron density combined with the electropositive nature of the B center make them highly unstable species. In this study, we present synthesis and full characterization of a complex in which Ph3B2− is sandwiched between two Sr2+ ions and describe ...

Le développement durable : enfant prodigue ou rejeton matriphage de la protection de la nature ?
Les Ateliers de l’Ethique, 2006 Bien qu’une forte incertitude pèse sur l’évaluation chiffrée de l’érosion de la biodiversité, et une incertitude plus grande encore sur les projections du déclin à venir, il n’y a pas de controverse sur le fait que le rythme d’extinction actuel en est un

Unconventional methods of strategic distribution of the incertitude [PDF]
The incertitude became a phenomenon in itself, and it can be due both to the theoretical errors of the deciding factor, and to the imprecision and lack of informational wholeness.

American Journal of Botany, EarlyView.Abstract Premise The soil depth of underground storage organs (USOs) of geophytes involves cost–benefit trade‐offs and may relate to USO age, size, and disturbances such as fire and herbivory. Yet determinants of USO depth are poorly studied. We posit that belowground mammalian predation of USOs is a selective force for the positive relationship ...
