Las limitaciones de la matriz hobbesiana en la actualidad política

open access: yesDoisPontos, 2009
In the present article we make two Hobbesian problems converge, to wit, what we call “Hobbesian Matrix” of the contemporary political culture and the “decisionist” aprouch of the order.

Linking Process‐Induced Degradation to Mechanical Property Deterioration in Flax Fiber–Reinforced Bio‐Polymer Matrix Composites

open access: yesPolymer Composites, EarlyView.
Effect of processing‐induced thermal degradation on the mechanical performance of thermoplastic flax fiber composites. ABSTRACT The drawback of biobased polymer matrix composites (PMCs) is their limited temperature stability, resulting from degradation, which restricts their processability in established composite manufacturing processes requiring ...

Global Health Governance Cannot Keep Relying on the Development‐Goals Model to Effectively Address Health Inequalities Around the World

open access: yesSustainable Development, EarlyView.
ABSTRACT The Sustainable Development Goals (SDGs) are nearing their end in 2030, and it is highly unlikely that many of the SDGs would be met by the target date. This calls for the urgent need for an upgraded approach or a new strategy from the “development‐goals” model.

Market regulation and productivity: The case of the Canadian Wheat Board

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Changes to regulatory environments influence firm‐level incentives, which can move the productivity frontier or reposition firms within an existing frontier. Estimating causal effects of policy changes requires a credible counterfactual for productivity in the absence of policy change.
