Mergers and Efficiency in Cooperative Milk Assembly and Manufacturing in the Southwest

This study is concerned with estimating the effects of cooperative mergers on the milk marketing efficiency in the Southwest United States. Specific objectives include determining a market structure that may have existed in the absence of cooperative mergers, and comparing assembly and processing costs under the alternative market structures.Agricultural Economic

Triggermuscle: Exploring Weight Perception for Virtual Reality Through Adaptive Trigger Resistance in a Haptic VR Controller

It is challenging to provide users with a haptic weight sensation of virtual objects in VR since current consumer VR controllers and software-based approaches such as pseudo-haptics cannot render appropriate haptic stimuli. To overcome these limitations, we developed a haptic VR controller named Triggermuscle that adjusts its trigger resistance according to the weight of a virtual object. Therefore, users need to adapt their index finger force to grab objects of different virtual weights. Dynamic and continuous adjustment is enabled by a spring mechanism inside the casing of an HTC Vive controller. In two user studies, we explored the effect on weight perception and found large differences between participants for sensing change in trigger resistance and thus for discriminating virtual weights. The variations were easily distinguished and associated with weight by some participants while others did not notice them at all. We discuss possible limitations, confounding factors, how to overcome them in future research and the pros and cons of this novel technology

FORECASTING FUTURE PRICE TRENDS IN THE U.S. FRESH AND PROCESSED POTATO MARKET

A "demand" model for fresh and processed potatoes is formulated. The price forecasts for 1983-1992 suggest rising trends for both retail prices in both nominal and real terms. In the next ten years, nominal fresh and processed prices are predicted to increase by 106 percent and 72 percent, respectively
