Evaluating large‐scale government investments in fertilizer adoption: The Ethiopian experience

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract We evaluate the impact of a large Government of Ethiopia intervention to raise fertilizer supply by establishing five fertilizer blending facilities supplying fertilizers tailored to local soil nutrient profiles. We rely on the phased geographic rollout of blending facility establishment to identify the causal effect on fertilizer use ...

Trial‐Based Hemolysis Modeling to Investigate Operating Modes of Continuous‐Flow LVADs

open access: yesArtificial Organs, EarlyView.
This work presents a methodology for determining online‐capable hemolysis models for continuous‐flow LVADs, derived from in vitro trials. The models are based on fitting a modified power law and applying the Lagrangian approach. They assist clinicians in selecting treatment strategies that minimize hemolysis, as demonstrated with the Sputnik1 LVAD ...

Cost–benefit analysis and ‘next best’ methods to evaluate the efficiency of social policies: As in pitching horseshoes, closeness matters

open access: yesAnnals of Public and Cooperative Economics, EarlyView.
Abstract Many policymakers are unwilling, or think that it is infeasible, to perform comprehensive cost–benefit analysis (CBA) of programmes in social policy arenas. What principles actually underlie CBA? An understanding is necessary to assess whether other evaluation methods are close enough to CBA to provide useful information on social efficiency ...

An extension of the basic local independence model to multiple observed classifications

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract The basic local independence model (BLIM) is appropriate in situations where populations do not differ in the probabilities of the knowledge states and the probabilities of careless errors and lucky guesses of the items. In some situations, this is not the case. This work introduces the multiple observed classification local independence model
