Optimization or Bricolage? Overcoming Resource Constraints in Global Social Entrepreneurship

Abstract: Resources play a vital role in the development of an entrepreneurial venture. For ventures operating in the public interest, the process of effective resource mobilization can be especially critical to the social mission. However, there has been limited empirical examination of the approaches used by social ventures to mobilize critical resources. We study two processes of resource mobilization -- optimization and bricolage, and examine the antecedent conditions that influence a venture’s selection of these processes. Our theory predicts that environmental munificence and organizational prominence have U-shaped associations with the use of bricolage and positive associations with the use of optimization. We test our hypotheses on a sample of 202 technology social ventures from 42 countries, and discuss implications for the social entrepreneurship and broader entrepreneurship literatures.

Nonparaxial Mathieu and Weber accelerating beams.

Abstract: We demonstrate both theoretically and experimentally nonparaxial Mathieu and Weber accelerating beams, generalizing the concept of previously found accelerating beams. We show that such beams bend into large angles along circular, elliptical, or parabolic trajectories but still retain nondiffracting and self-healing capabilities. The circular nonparaxial accelerating beams can be considered as a special case of the Mathieu accelerating beams, while an Airy beam is only a special case of the Weber beams at the paraxial limit. Not only do generalized nonparaxial accelerating beams open up many possibilities of beam engineering for applications, but the fundamental concept developed here can be applied to other linear wave systems in nature, ranging from electromagnetic and elastic waves to matter waves.

Exploring individual and institutional drivers of proactive environmentalism in the US Wine industry

Abstract: Industry transformation related to environmental stewardship proceeds through multiple stages, and there is as of yet no clear understanding of the importance of certain drivers of transformation at different stages. We bring together previous environmental management research regarding individual- and institutional-level drivers of environmental stewardship to develop a model and series of questions regarding proactive environmental behavior in the US wine industry. A qualitative research method, including interviews and focus groups, is used to test the model. At the early stage of environmental transformation in the wine industry, we find that managerial attitudes and norms, existing regulations, employee welfare and competitive pressures are all strong drivers of proactive environmental behavior. However, our multi-level analysis suggests that drivers of environmentalism vary in relevance and relative importance and that future environmental management research needs to consider the relationship between drivers of environmentalism and the stage of an industry's environmental transformation.
