The Reflexive Producer: The Influence of Farmer Knowledge Upon the Use of Bt Corn*

Abstract This paper examines the influence of farmer knowledge upon decision making processes. Drawing upon the sociological debates around the ideas of reflexive modernity and biotechnology as well as from classic adoption and diffusion studies, I explore the influences upon farmers' use of Bacillus thuringiensis (Bt) corn. Utilizing survey data gathered from corn farmers in Minnesota and Wisconsin, I argue that farmers are ‘reflexive’ actors who actively negotiate between ‘expert’ and ‘local’ knowledges when deciding to plant Bt corn. Furthermore, I hypothesize that farmers are more likely to be influenced by their first‐hand or local experiences than by state or expert observations.     

SCHEDULING HYBRID FLOWSHOPS IN PRINTED CIRCUIT BOARD ASSEMBLY LINES*

We treat a three‐stage hybrid flowshop for the production of printed circuit boards (PCB), suggested to us by a real‐life production situation. The problem is to determine a schedule that minimizes the makespan for a given demand profile over a finite planning horizon. We propose a global procedure that utilizes genetic algorithms and three subproblems. The performance of the procedure is evaluated via experimentation over thousands of problem realizations that are randomly generated. The experimental results show the efficiency of the global procedure and provides qualitative answers to the allocation of machines to the various stages.
