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.

American Journal of Agricultural Economics, EarlyView.Abstract Large‐scale land reforms constitute a substantial redistribution of wealth and reallocation of agricultural land, which is a major form of asset and production input in developing countries. While land redistribution (from the rich to the poor) remains a highly controversial issue, extensive evidence on its effect is limited.

The role of venture‐financed startups in innovation for US agriculture
American Journal of Agricultural Economics, EarlyView.Abstract To evaluate the role played by startup companies in the innovation ecosystem of US agriculture, we compile a unique dataset of 6024 new entrants founded 1987–2019 that details their financing lifecycles, annual economic performance, and patenting activities.

American Journal of Industrial Medicine, EarlyView.ABSTRACT Background Homecare aides (HCAs) are professional non‐family caregivers, who support dependent individuals to live at home with dignity; yet in Spain they remain understudied and vulnerable, often facing precarious working conditions. We aimed to characterize HCAs’ employment, living conditions, health, and exposure to workplace violence and ...

Journal of Applied Polymer Science, EarlyView.Kevlar is traditionally modeled as a rigid‐rod polymer, yet rheological behavior deviates from this assumption. The review introduces a novel “twist‐tie” entanglement theory for aramid polymer chains in the nematic liquid crystal state, providing a molecular explanation for deviations from rigid‐rod models. Understanding twist‐tie entanglement dynamics

Integral representations of the solutions to the homogenized transport equations [PDF]
This paper provides two general representations of the weak limit u(t,x) of the solution uε(t,x) for (t,x) ∈ (0,T)×Rd, to the linear transport equation with an oscillating regular velocity b(x/ε), an initial datum u0ε(x) and a right-hand side fε(t,x ...

Journal of Applied Polymer Science, EarlyView.Microwave‐assisted alcoholysis converts EVA into EVAOH terpolymers, promoting a progressive transition from EVA‐like crystallites to VOH‐rich hydrogen‐bonded crystalline domains. Solvent‐controlled swelling influences conversion kinetics, while thermal analysis reveals a sigmoidal increase in melting temperature that a two‐population crystallization ...

A methodological framework for Monte Carlo probabilistic inference for diffusion processes [PDF]
, 2009 The methodological framework developed and reviewed in this article concerns the unbiased Monte Carlo estimation of the transition density of a diffusion process, and the exact simulation of diffusion processes.

Journal of Applied Polymer Science, EarlyView.Cooling holes provide a simple passive cooling strategy for polymer spur gears, reducing maximum operating temperature by up to 9.39% while introducing a measurable gear mesh stiffness penalty. A validated response‐surface model reveals how hole size and location govern this thermal–mechanical trade‐off, enabling design optimization for thermally and ...
