Redistributive land reforms, agricultural productivity, and structural change: New cross‐national evidence

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.

Choice experiments on land managers' participation in environmental programs: A systematic review and meta‐analysis of estimate validity

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 ...

Hierarchical control-based fault ride-through of VSC-HVDC considering impacts of renewable energy

International Journal of Electrical Power & Energy Systems
When a short-circuit fault occurs at the receiving-end grid, the unbalanced power in voltage source converter based high voltage direct current (VSC-HVDC) should be consumed to prevent excessive DC voltage rise, thereby enabling fault ride-through ...

Risk management externalities in agrifood supply chains

American Journal of Agricultural Economics, EarlyView.
Abstract Firms may under‐ or over‐invest in risk management from the social planner's perspective, resulting in a negative externality on other economic agents in the supply chain. The externality of risk management is particularly relevant for agrifood supply chains, which frequently experience disruptions and play a primary role in preventing major ...

Income sharing for common pool resources with uncertain productivity

American Journal of Agricultural Economics, EarlyView.
Abstract We address the interconnected issues of externalities in the use of a natural common‐pool resource system and adverse effects of environmental uncertainty on risk‐averse resource users. We set up a simple analytical model and derive conditions such that insurance by means of an income sharing mechanism mitigates externalities and hence ...

Cerebellar Abnormalities in the Neuroimaging Spectrum of CLTC‐Related Disorder

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Pathogenic variants in CLTC, which encodes the clathrin heavy chain involved in vesicle‐mediated trafficking in neurons, cause a rare neurodevelopmental disorder associated with variable severity of global developmental delay and intellectual disability and structural brain abnormalities. Although corpus callosum and white matter anomalies are

Study on fault ride-through control of islanded wind farm connected to VSC-HVDC grid based on the VSC converter AC-side bus forced short circuit

The Journal of Engineering, 2019
Wind farms integrated to an AC power system through a voltage source converter-based high-voltage direct current system (VSC-HVDC) are viewed as islanded wind farms. The wind farm side converter of VSC-HVDC maintains a constant frequency of the wind farm

Artificial Intelligence and Access to Justice at the ‘Shop Front’: The Potential and Limitations of Meeting Legal Need Through Technology

Australian Journal of Social Issues, EarlyView.
ABSTRACT In Australia, governments fund Community Legal Centres (CLCs) as part of the legal assistance sector (LAS) to meet the ‘legal needs’ of people experiencing disadvantage who cannot afford private legal services. Persistent unmet demand for CLCs is well‐documented. As artificial intelligence (AI) is increasingly used in private legal practice to
