Non-Abelian Discrete Groups from the Breaking of Continuous Flavor Symmetries
We discuss the possibility of obtaining a non-abelian discrete flavor
symmetry from an underlying continuous, possibly gauged, flavor symmetry SU(2)
or SU(3) through spontaneous symmetry breaking. We consider all possible cases,
where the continuous symmetry is broken by small representations. "Small"
representations are these which couple at leading order to the Standard Model
fermions transforming as two- or three-dimensional representations of the
flavor group. We find that, given this limited representation content, the only
non-abelian discrete group which can arise as a residual symmetry is the
quaternion group D_2'.Comment: 15 page

Working Arrangements of Fruit and Vegetable Processing Cooperatives
Organization and operations of nine working arrangements developed by fruit and vegetable processing cooperatives are described and evaluated. Three distinct approaches are identified - contractual agreement, affiliation through membership status, and formation of separate business entity. The specific structure and functions of joint undertakings reflect the needs and preferences of the participants. Benefits perceived in the cases cited included scale economies in processing and marketing, capital cost avoidance, product diversification, assured commodity supply, and enhanced market entry.Fruit and vegetable cooperatives, joint ventures, contractual agreements, marketing services, processing services, Agribusiness,
