Using longitudinal panel data from the Western Chitwan Valley of Nepal, this study investigates the impact of the use of modern farm technologies on fertility transition-specifically, the number of births in a farm household. Previous explanations for the slow pace of fertility transition in rural agricultural settings often argued that the demand for farm labor is the primary driver of high fe...
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...
The study's aim was to assess the robustness of farm-type anaerobic digestion with cattle slurry as main feedstock under change co-feedstock type and quality. Fish biomass, rainbow trout offal, potato, reindeer offal were investigated possible co-feedstocks in a 428-day semi-continuous reactor experiment. Using fish biomass or (19 % VS feed) produced an average 220 305 L CH 4 /kg compared 201 f...
Fish farming is promoted in the Republic of Benin to meet demands fish consumption and increase exports neighbouring countries. Targeting farm policy interventions efficiency heterogeneous systems a challenge. Farm type delineation allows for simplifying diversity systems. Multivariate statistical techniques combined with Calinski Harabasz pseudo F statistic bootstrapping were applied determine...
Abstract This study gives a deeper understanding of how service providers think and work when offering farm-based days care (FDC) services for people with dementia. Seven semi-structured interviews providers, analyzed using text condensation, resulted in the five main themes; “On fertile ground”; “The foundation”; “Activities rippling effects”, “Positive social emotional environment” and, “Maki...
