| Data on net turnoff for small, medium-sized and large cow-calf and small and large size yearling ranches were tested for normality using the Shapiro - Wilk test. The yield data examined were accepted as normally distributed at the alpha = .10 level. The probability of profit for each type of ranch was assessed using normal curve techniques for nine different cost-price alternatives and weather conditions. Yearling cattle ranchers had higher profit probabilities than cow-calf ranchers. Prices received had more influence on profit probabilities than weather conditions. |

| For many international students who study agricultural economics in the United States, English is not their first language nor the language of academic instruction in their home country. This paper evaluates a program designed to permit international students with English deficiencies to begin their graduating training while simultaneously taking an intensive course in English as a second language. It is found that there is no significant difference in the performance of students in this program and other international students who begin their training with a capability in English. |

| This paper demonstrates the differences that result from estimating coal demand functions using highly aggregated regional data rather than less aggregated state data. At first glance the coal demand functions based on regional data appear to explain well and seem useful in policy making. However, coal demand functions based on state data show differences in the demand structure in each state of the region. Policy decisions that may seem appropriate based on aggregated regional data may have much different impacts on individual states in the region. |
