In the mid 1980s, Brassica vegetable production in southern Queensland was at crisis point with insecticide resistance in diamondback moth, Plutella xylostella (L.), leading to frequent spray failures. Through a succession of projects, an Integrated Pest Management (IPM) system targeted at the local Brassica pest complex was developed with farmers and industry using participative processes. Str...

By comparing the network structure of venture capital (VC) firms in Silicon Valley (California) to that of VC firms in Route 128 (Massachusetts), the present study challenges any market-centred theory of regional development. I show that there are advantages in examining the structure of social networks of cooperation within the venture capital industry to understand the level of development of...

This article treats social capital as a multidimensional phenomenon along which neighborhoods are differentially organized. The authors assess this notion by linking two original surveys carried out in Chicago based on community residents (N = 8,782) and positional leaders (N = 2,822) representing six organizational dimensions. These data are used to examine both the dimensionality and structur...

Unlike previous studies, the model in this paper includes network externalities in both the human capital investment stage and the subsequent career stages. This implies that not on...
