| The dichotomy between perceptions of the acceptability of risk associated with genetically modified (GM) foods and willingness to consume GM foods is investigated. Results indicate that some consumers are willing to consume GM foods even though they may perceive such foods as somewhat unsafe, with determinants such as self-perceived knowledge about the availability of GM foods and altruistic motives having positive and significant effects on their consumption decisions. Efforts toward decreasing perception of risk and ultimately increasing acceptance of and demand for GM foods should address issues related to their altruistic characteristics and outrage. |

| Participation in an international study program provides students with invaluable exposure to another culture and a multitude of academic and life experiences. Rapid advances in communication technologies now make it possible for students to share these experiences with their support network at home as they occur. The responsibility of doing so by means of a web page built on-location 1) motivates students to increase their awareness of, and participation in, their surroundings, 2) changes how students view their surroundings and activities in which they participate, 3) increases content learning, 4) extends the number of people involved in the international study program, and 5) results in a professional written and visual documentary.

| Canadian exports of beef and live cattle to the United States have increased significantly since the late 1980s. Hog exports have increased since the mid-1990s. Major factors affecting exports of beef, pork, cattle, and hogs from Canada to the United States include the exchange rate, increased Canadian production, U.S.-Canada price differentials, and trade liberalization under the Canada - United States Free Trade Agreement (CUSTA) of 1989. Increased Canadian exports have resulted in small but significant reductions in U.S. domestic prices of beef, pork, and hogs. |

| University students took part in an experimental auction designed to elicit and estimate the influence of information bias on consumer willingness to pay for GM versus non-GM food products. Surveys before and after the auction queried participants on their perceptions about GM foods and the associated risks, and their beliefs and attitudes about the interaction between farming practices and the environment. Students received either positive- or negative-biased information about the impact of biotechnology on the environment during the auction. Consumer perceptions were influenced by information bias. |

| Bid prices were elicited for standard-label cookies, muffins, and potato chips and those identified as not including genetically modified (GM) ingredients using an experimental auction. Including a statement that the product did not include GM ingredients increased bids over those offered for standard-label products. Providing negative-biased information about the impact of GM crops on the environment increased the risk participants associated with GM foods, and positive-biased information decreased perceived risk. Overall, providing impact information, whether positive- or negative-biased, increased bids for products presumed GM. The influence of information bias on bids varied among selected participant groups, supporting the presence of uniquely... |

| Co-products of processing agricultural commodities are often marketed through private transaction rather than through public markets or those in which public transaction information is recorded or available. The resulting lack of historical price information prohibits the use of positive time series techniques to estimate demand. Demand estimates for co-products are of value to both livestock producers, who obtain them for use in livestock rations, and processors, who must sell or otherwise dispose of them. Linear programming has long been used, first by researchers and later as a mainstream tool for nutritionists and producers, to formulate least cost livestock rations. Here it is used as a normative technique to estimate step function demand... |

| A framework which permits estimation of economically optimal stocking rates for alternative economic parameters and alfalfa forage availability was developed and applied to a controlled grazing experiment conducted with Holstein steers (243 kg) placed on direct seeded alfalfa pastures in Central Michigan. Responses of ADG to alternative levels of forage availability per standard livestock unit (FA) were summarized by a quadratic function and the associated gains/ha were calculated. The ADG decreased as standard stocking rate (SSR; SLU/ha) increased except for the combination of the lowest observed SSR and highest FA, where ADG was curvilinear as SSR increased. The trend for gain/ha was curvilinear for all FA. The SSR which maximized gain/ha increased... |

| Student satisfaction with and performance in an on-line agrisales course is compared with that of students enrolled in a simultaneously-taught classroom course. Assessment tools are developed for both sections. Online and classroom students were equally satisfied with the course and the instructor using most measures, but had different motivators for course enrollment. Overall student performance did not differ, but the composition of such was unique for each group. Results suggest instructors be well prepared to handle unique learner situations prior to marketing an online course. |

Assessment tools are developed for both sections. Online and classroom students were equally satisfied with the course and the instructor using most measures, but had different motives for course enrollment. Overall student performance did not differ. However, online students tended to do better on exams and homework assignments while classroom students demonstrated a greater ability to apply course concepts to a practical setting. Results suggest instructors be well-prepared to handle unique learner situations prior to marketing an online course and work to ensure students are motivated to... |

| Student satisfaction with, and performance in, a first-offer online agrisales course was compared with that of students enrolled in a simultaneously-taught classroom course. Online and classroom students were equally satisfied with the course and the instructor using most measures, and student overall performance did not differ. However, online students tended to do better on exams while classroom students demonstrated a greater ability to apply course concepts to a practical setting. Changes were made in the online course to improve student understanding of and ability to apply course concepts. Specifically, online student exams were no longer open-note / open-book and were proctored. On-campus online students also participated in their final sales... |
