Última Diffusion of Innovations on Community Based Small Worlds: the Role of Correlation between Social Spheres AgEcon Tanimura, Emily. Which types of networks favor the diffusion of innovations in the sense that an innovation whose intrinsic benefits are greater than those of an established choice will be able to replace the latter when it is initially used only by a small fraction of a large population? For deterministic and regular networks there are characterizations, based on a coordination game model of the diffusion of innovations. Here we study this question for a class of irregular random networks, Small world networks, which are of interest as more realistic models of social networks. We consider a random graph model based on a community structure, in which the choice of a parameter allows us to obtain as special cases several well known models, in particular Watts' Small world....

Ano: 2010 URL: http://purl.umn.edu/96842 THE ADOPTION OF IPM TECHNIQUES BY VEGETABLE GROWERS IN FLORIDA, MICHIGAN AND TEXAS AgEcon Fernandez-Cornejo, Jorge; Beach, E. Douglas; Huang, Wen-Yuan. Factors influencing the adoption of Integrated Pest Management (IPM) techniques are studied using survey data from individual vegetable producers from Florida, Michigan, and Texas. Farmers who adopt IPM tend to be less risk averse and use more managerial time on farm activities than nonadopters. Adopters are also more likely to operate large, irrigated farms and use more family labor. Locational factors and the type of crop grown are also influential in IPM adoption. The analysis uses a logit framework and introduces adopter categories first conceptualized by rural sociologists.

Ano: 1994 URL: http://purl.umn.edu/15441 Adopting New Zealand Dairy Farm Principles and Practices in Argentina AgEcon Peluffo, Matias; Shadbolt, Nicola M.. The dairy sector is important to Argentina because it creates genuine wealth and employment. Milk production at competitive costs is crucial for the endurance of the Argentine dairy sector; therefore the development of competitive dairy farm systems is important for Argentina. New Zealand (hereafter NZ) dairy farm systems are internationally known for their competitiveness without the presence of subsidies. Though Argentine dairy farmers have been attracted to NZ systems for more than 40 years and despite the fact that the NZ knowledge appears to be beneficial to Argentine farms, NZ practices have been rarely adopted. This seemingly fruitless effort in extending this technology shapes the research question of the present study: Can Argentine dairy farmers...

The objective is to analyse the diffusion over time process of the knowledge and adoption of a sustainable technological innovation -organic agriculture- in the South of Spain -Andalusia region- and for a crop of paramount importance there -olive- within the framework of the Diffusion of Innovations Theory. Results show that diffusion is essentially due to an autonomous "contagion" among olive growers with a little external intervention. In many regions, particularly in low yield conditions, adoption of organic farming has come to an standstill, demonstrating the need to strengthen or modify the mechanisms of diffusion commonly used up to this time.
