In this study, we argue that while community forest management is effective in protecting forest resources as argued by Ostrom, it may fail to provide proper incentives to take care of such resources because of collective sharing of benefits of forest management. This study proposes a mixed...

SUMMARY We propose a method for detecting changes in the order balance in stock markets by applying a stochastic model to the feature vectors extracted from the order‐book data of stocks. First, the data are divided into training and test periods. Next, a Gaussian mixture model is estimated...

A power router has been recently developed for both AC and DC applications that has the potential for smart-grid applications. This study focuses on three-phase power switching through the development of an experimental setup which consists of a three-phase direct AC/AC matrix converter with a...

In recent years, shade coffee certification programs have attracted increased attention from conservation and development organizations. The certification programs offer an opportunity to link environmental and economic goals by providing a premium price to producers and thereby contribute to...

This study estimates the effect of farmer field schools in rural Ethiopia on income from agriculture. The farmer field schools were established in association with participatory forest management associations for forest protection funded by Japanese aid. We employ a difference-in-differences...

This study uses remote sensing data to quantitatively examine the impact of establishing participatory forest management associations in Ethiopia. The results indicate that where there is a forest association, forest area declines more in the year the association is established than it does in a...

The dispatching properties of power packets in indoor power line channel were investigated. A power packet is physically composed of a power payload and information signals. For evaluation, the arrival power ratio and the bit error rate were calculated by numerical simulation. The results are...
