Exploring the use of Controlled English for communication with ACT-R agents

Research is being undertaken into sense-making by collaborative agents, based upon a cognitive framework of human behaviour, ACT-R, together with communication between the agents. We explore the use of Controlled English for this purpos

A Brief Summary of U.S. Farm Program Provisions

This brief publication began as a need for a short summary of farm programs and farm bills for two agricultural economics courses focusing on agricultural policy -- ag. economics 429, and ag. economics 614. It became clear that many students taking these courses had less and less background in agriculture and less (even cursory) knowledge of policies than those of the recent past. After this list was developed a number of other professional agricultural economists found copies and began to use it, hence its publication in a more structured form. The list of Farm Program Provisions is not all-inclusive. It certainly does not contain all the laws and provisions that have affected agriculture over the years. However, it is an easy reference to farm bills and provisions since 1933. We intend to update this list as time goes on to continue its usefulness to professionals and students alike.Agricultural and Food Policy,

ECONOMETRIC MODEL OF THE U.S. SHEEP INDUSTRY FOR POLICY ANALYSIS

The U.S. sheep inventory has been declining for many years. To further investigate this trend, an econometric sector model using single demand equations was developed to analyze the impacts of two alternative levels of wool marketing loan rates.Marketing,

The Impact of Land Fragmentation on Beef Cattle Inventory

Many groups have discussed with alarm the impact of agricultural land conversion to non-agricultural uses. This research indicates little evidence that beef cow inventory has been negatively affected by land fragmentation. Average acres per transaction, total transactions, or a fragmentation index did not have an important effect on cattle inventory.Land Economics/Use, Livestock Production/Industries,

Short-term climate response to a freshwater pulse in the Southern Ocean

The short-term response of the climate system to a freshwater anomaly in the Southern Ocean is investigated using a coupled global climate model. As a result of the anomaly, ventilation of deep waters around Antarctica is inhibited, causing a warming of the deep ocean, and a cooling of the surface. The surface cooling causes Antarctic sea-ice to thicken and increase in extent, and this leads to a cooling of Southern Hemisphere surface air temperature. The surface cooling increases over the first 5 years, then remains constant over the next 5 years. There is a more rapid response in the Pacific Ocean, which transmits a signal to the Northern Hemisphere, ultimately causing a shift to the negative phase of the North Atlantic Oscillation in years 5–10

The Impact of the National Counter-Cyclical Income Support Program for Dairy Producers on Representative Dairy Farms

This report contains the results of an analysis of the National Counter-Cyclical Income Support Program for Dairy Producers on the Agricultural and Food Policy Center’s (AFPC) representative dairy farms. The impact of the proposal on the representative farms is evaluated in terms of the change in average annual cash receipts and the change in the average annual net cash farm income. The role and potential importance of payment limits on these farms are discussed. All milk prices by state and program benefits under the payment limit binding and nonbinding scenarios were developed by FAPRI and were applied to the representative dairies. For more information on those results see the FAPRI analysis of this program.Agribusiness, Agricultural and Food Policy, Livestock Production/Industries,

Can We Save the Traditional Family Farm?

What is a traditional family farm? Is it a family of four living on a farm and supplying all of the labor, capital and management or is it a family corporation with four families supplying all of the capital and management? These types of questions continue to arise in policy debates, as they have for many years. While subject to heated debate and the core of many people’s positions on farm programs the answer is more sociological as it is becoming less and less economically relevant. Whether these types of farms or any other farm sizes should survive is not a question that can be answered by a policy analyst. The job of an analyst is to determine if and under what conditions family farms can survive. To this end, this paper reviews the various definitions of family farms and draws inferences as to the economic and financial survival of these different size farms using the results generated from simulating representative farms.Agricultural and Food Policy,

The Effectiveness of Dairy Risk Management at Managing Income, Revenue, and Margin Risk

With the 2009 milk prices still fresh on everyone’s mind, there has been increased interest in ways to limit milk price volatility. Using SERF, this paper determined some dairies are willing to pay for limited milk price volatility and found a value they are willing to pay using risk premiums.Dairy, Stochastic Simulation, price volatility, Agricultural and Food Policy, Farm Management,

Regional and Structural Impacts of Alternative Dairy Policy Options

Milk and dairy product prices have fallen to their lowest levels in 3 years following the record highs of 2004 and 2005. The large government stockpiles of non-fat dry milk are gone, but threaten to build again as non-fat dry milk and cheese prices decline nearer the support price level. A new farm bill is scheduled to be written in 2007. The Milk Income Loss Contract (MILC) program included in the last farm bill was only authorized through September 2005. Subsequent legislation reinstated the MILC program through August 2007. WTO negotiations are on-going and could influence U.S. farm programs 1/. Dairy’s role in the U.S. amber box limit of $19.1 billion may necessitate some possible trade-offs with other commodities. Dairy counts about$4.2 billion toward the annual amber box limit, but actual spending only averages about $1 billion (Outlaw, et al). The pressure of low prices, WTO negotiations, MILC continuation, and a new farm bill has created the potential for a number of options and alternatives for dairy policy. This paper examines the regional and structural impacts of 3 dairy policy options: MILC continuation, a target price/deficiency payment program, and an increase in the support price. All three options are designed to spend$400 million in amber box payments per year. The analysis uses representative dairy farms in major milk producing regions of the country developed by the AFPC for policy analysis.Agribusiness, Agricultural and Food Policy, Livestock Production/Industries,
