This article studies the relationship between the off-farm participation behavior of farm operators and their spouses and the demographic composition of the household. I focus on farm families without parents, siblings or partners, and examine the effects of the existence of elderly children of the farm couple. I find that both the father and the mother tend to reduce their participation in off...

This paper presents the wind farm simulation model developed in the EU-FP7 project, AEOLUS. The idea is to provide a publicly available simulation package for researchers developing farm level control solutions. With the software it is possible to auto generate a wind farm simulation model in Matlab/Simulink based on turbine parameters and farm geometry. The input to the farm simulator is power...

Korean pig farms face challenges from free trade environment. Many farms have adopted Information System to improve the productivity on the farm. This study applies statistical analysis to verify the productivity gain and its determinants by using information system on the pig farm. Using the farm level weekly data from the PigPlan from 2006 to 2012, we find productivity gain on the farm increa...

In a wind farm, the wakes formed by upstream wind turbines decrease the power outputs of downstream wind turbines by reducing wind speed. This wake interference significantly lowers the power production of a wind farm, especially that of a large-scale wind farm. In this paper, we express wind farm power as a differentiable function of location variables. We then apply a sequential convex progra...

OBJECTIVE The main objective of this study was to systematically review the existing evidence for the effectiveness of farm injury prevention interventions. SEARCH STRATEGY We used a systematic approach to search the following electronic databases: MEDLINE, EMBASE, ERIC, PsycInfo, Sociofile, NTIS, Agricola, Expanded Academic Index, Dissertation Abstracts, and Occupational Safety and Health (N...

This paper considers the use of spatial microsimulation in the aggregation of regional environmental benefit values. The developed spatial microsimulation model uses simulated annealing to match the Irish Census of Agriculture data to a Contingent Valuation Survey that contains information on Irish farmers’ willingness to pay (WTP) to have the corncrake restored as a common sight in the Irish c...

The transmission risk of foot-and-mouth disease (FMD) in Japan was evaluated using a mathematical FMD transmission model. The distance-based transmission rate between farms, which was parameterized using the FMD epidemic data in 2010 in Japan, was used to calculate the local-level reproduction numbers-expected numbers of secondary infections caused by one infected farm-for all cattle and pig fa...

This research evaluates the efficiency of swine firms differing by specialization type and employed technologies. Measures of technical, allocative, scale, economic, and overall efficiency are separately and jointly estimated for farrow-to-finish, farrow-to-feeder, feeder-tofinish, farrow-to-weanling, weanling-to-feeder, and mixed operations. Findings confirm appreciable differences in efficien...

Next-generation sequencing (NGS) approaches are widely used in genome-wide genetic marker discovery and genotyping. However, current NGS approaches are not easy to apply to general outbred populations (human and some major farm animals) for SNP identification because of the high level of heterogeneity and phase ambiguity in the haplotype. Here, we reported a new method for SNP genotyping, calle...

This paper examines the factors that influence the earned income of organic farmers, given their decisions to engage in local selling. The model explicitly accounts for the sorting of producers across different levels of commitment to local sales on the basis of both observable and unobservable heterogeneity. The significant selectivity coefficients confirm that when producers choose to market ...
