The technique of the processor farm has become very widely used for paral-lelising applications, often being mentioned without reference to any source. The goal of this work has been to put together a complete and rigorous understanding of what the technique can be used for and what is needed in order to arrive at an eeciently farmed application. This paper consists of these two parts. We have ...

This contribution is based on the personal experiences of the author as a typical crop farmer in Holland in 1925-1991, as a researcher at the Dutch Institute of Agricultural Engineering (19541964), and as the Director of that Institute in the period 1964-1983. In essence, the 20th century developments in mechanized agriculture are considered from a historical perspective. The future of farm mec...

targeted extension for heterogeneous farming systems is a challenge in developing countries. farm type identification and characterization based on estimates of income from different farm components allows simplifying diversity in farming systems. use of multivariate statistical techniques, such as principal component analysis (pca) and cluster analysis (ca), help in such farm typology delineat...

Every year, the United States employs nearly two million seasonal farm laborers, approximately half of whom are migrants (Rothenberg 1998). This article utilizes one year of participant observation on a berry farm in Washington State to analyze hierarchies of ethnicity and citizenship, structural vulnerability, and health disparities in agriculture in the United States. The farm labor structure...

This work uses unique data from three dairy dependent communities in rural Wisconsin to test established theory and empirical studies that link farm structure to local purchasing patterns and community economic development. A theoretical model of purchasing choices is developed to derive the determinants of local purchasing by dairy farms. This model is tested empirically using a double bounded...

Today people have become more and more dependent on search engines such as Google, Yahoo, and MSN, etc., for their information needs. Web spamming has emerged to take the economic advantage of high search rankings and threatened the accuracy and fairness of those rankings. Understanding spamming techniques is essential for evaluating the strength and weakness of a ranking algorithm, and for fig...

This study aims to analyze the determinants of vertical integration (ownership and contract-ing) among peasant farmers in Northern Algeria. The choice of asset control is between ownership and a simple contracting. Thus, the integration of vertical stages of agricultural produc-tion leads to higher gross margins, influences the choice of marketing and supply channels, and improves market partic...
