This paper explores the dynamics of smallholder technology adoption, with particular reference to a high-yielding, low-external input rice production method in Madagascar. We present a simple model of technology adoption by farm households in an environment of incomplete financial and land markets. We then use a probit model and a symmetrically trimmed least squares estimation of a dynamic Tobi...

This paper is concerned with some feasibility issues in mathematical programs with equilibrium constraints (MPECs) where additional joint constraints are present that must be satis ed by the state and design variables of the problems. We introduce su cient conditions that guarantee the feasibility of these MPECs. It turns out that these conditions also guarantee the feasibility of the quadratic...

In two-sided and coalition matching games, agents must all agree for a match to be formed, and agents can make only a finite number of matches. I examine the nonparametric identification and estimation of match production functions in matching games with endogenous prices and transferable utility. Inequalities derived from necessary conditions for equilibrium underly a nonparametric maximum sco...

Segmentation of femurs in Anterior-Posterior x-ray images is very important for fracture detection, computer-aided surgery and surgical planning. Existing methods do not perform well in segmenting bones in x-ray images due to the presence of large amount of spurious edges. This paper presents an atlas-based approach for automatic segmentation of femurs in x-ray images. A robust global alignment...

Information Technology (IT) adoption is an important field of study in a number of areas, which include small and medium-sized enterprises (SMEs). Due to the numerous advantages of IT, SMEs are trying to adopt IT applications to support their businesses. IT adoption by SMEs differs from larger organizations because of their specific characteristics, such as resources constraints. Therefore, thi...

AbstractThe challenges of agroforestry systems’ adoption by farmers in the North central zone of Nigeria, was carried out to address the following objectives; find out the perception of farmers on agroforestry technologies, identify the adoption level and ascertain why farmers discontinue agroforestry adoption.. Data were collected from 722 agroforestry farmers out of 782 sets of questionnaire ...

Background Systems Thinking (ST) has recently been promoted as an important approach to health systems strengthening. However, ST is not common practice, particularly in Low- and Middle-Income Countries (LMICs). This paper seeks to explore the barriers that may hinder its application in the Eastern Mediterranean Region (EMR) and possible strategies to mitigate them.   Methods A survey consistin...
