American Native Beef Cooperative

The American Native Beef project involved a failed attempt to establish cow and bull slaughter operation in Southeast Oklahoma. The effort was initially organized as a new generation cooperative and raised over US$2.5M from area producers who retained their funds in escrow for over 5 years despite numerous opportunities to withdraw their investment. The business model was restructured several times to attract equity capital from outside investors. The case provides insights into the linkages between business strategy and business structure. It also raises the question as to whether the project could have been successful under the original business model.Agribusiness, Livestock Production/Industries,

Factors Impacting Participation In and Purchases Made by Members of the Oklahoma Food Cooperative

The Oklahoma Food Cooperative (OFC) facilitates transactions between producers and consumers of locally-grown food items. Even with more than 3,000 members and roughly $1M in annual sales, the OFC still needs to establish its long-term sustainability. Both customer-members and supplier-members of the OFC were surveyed to determine the factors driving their current and continued participation in the cooperative.cooperative, local food movement, member communications, business sustainability, strategic planning, Agribusiness, Institutional and Behavioral Economics, Marketing,

Feasibility of a Co-operative Winery

The number of operating wineries in the United States has doubled during the past decade. Most of this growth has been due to a large number of entrepreneurial landowners developing their own small acreage vineyards and trying to branch into winemaking. However, wineries are capital-intensive enterprises which require high initial investment and experience lagged cash flow associated with the time between the purchase of grapes and initial wine sales. Additionally, the availability of local grape production often limits the production capabilities of an entrepreneur’s small winery. As a result, some vineyard owners consider establishing co-operative wineries. This paper describes a feasibility assessment tool developed to assist vineyard owners in examining the potential for a co-operative winery and provides an example of how this tool can be used to examine a number of co-operative operating scenarios.co-operative, feasibility template, qualified and nonqualified stock, revolving equity, winery, Agribusiness, Financial Economics,

Effect of Mn doping on ultrafast carrier dynamics in thin films of the topological insulator Bi2Se3

Transient reflectivity (TR) measured at laser photon energy 1.51 eV from the indirectly intersurface coupled topological insulator Bi2-xMnxSe3 films (12 nm thick) revealed a strong dependence of the rise-time and initial decay-time constants on photoexcited carrier density and Mn content. In undoped samples (x = 0), these time constants are exclusively governed by electron-electron and electron-phonon scattering, respectively, whereas in films with x = 0.013 - 0.27 ultrafast carrier dynamics are completely controlled by photoexcited electron trapping by ionized Mn2+ acceptors and their dimers. The shortest decay-time (~0.75 ps) measured for the film with x = 0.27 suggests a great potential of Mn-doped Bi2Se3 films for applications in high-speed optoelectronic devices. Using Raman spectroscopy exploiting similar laser photon energy (1.58 eV), we demonstrate that due to indirect intersurface coupling in the films, the photoexcited electron trapping in the bulk enhances the electron-phonon interaction strength in Dirac surface states
