MEASURING THE EFFECT OF INCREASED HORTICULTURAL IMPORTS: AN APPLICATION TO WINTER VEGETABLES

This report describes and applies a methodology to measure the impact of increased horticultural imports on U.S. vegetable producers. The methodology is applied to a hypothetical surge in winter vegetable imports. The paper describes how Florida winter vegetables could be affected by both short-term and long-term changes in import availabilities.Florida, imports, Mexico, trade model, winter vegetables, Crop Production/Industries, International Relations/Trade,

U.S. IMPORTS OF CANADIAN WHEAT: ESTIMATING THE EFFECT OF THE U.S. EXPORT ENHANCEMENT PROGRAM

It is hypothesized that the U.S. Export Enhancement Program (EEP) has had a role in increased U.S. imports of Canadian wheat. Using a set of world wheat models that differentiate wheat according to class and source, several conclusions concerning the role of EEP are reached. Over the period 1986-1993, EEP has been accountable for 40 to 48 percent of the yearly growth in U.S. imports of Canadian wheat. EEP subsidies in 1991/92 to China and Brazil caused significant diversion of Canadian wheat that would have been destined for those markets instead to the U.S. market. Further, it is argued that a quota on imports is not likely to have price-enhancing effects for U.S. wheat.Canada, export enhancement program, wheat, Agricultural and Food Policy, International Relations/Trade,

The Common Core: An Enhancement or Hindrance for the Youth of America?

Education in America differs from other nations and may benefit from modeling some of these foreign practices. Although there are many improvements that the country could make, curriculum could be one of the sources of inadequacy in the education system and is often what receives the most attention. Therefore, the subsequent sections will explore the United States’ major attempt in improving education through creating consistency through the Common Core curriculum. In all, if the United States seeks to maintain its power in various sectors, it must strengthen its education system to ensure success

The Value of Evidence-Based Computer Simulation of Oral Health Outcomes for Management Analysis of the Alaska Dental Health Aide Program

Objectives: To create an evidence‐based research tool to inform and guide policy and program managers as they develop and deploy new service delivery models for oral disease prevention and intervention. Methods: A village‐level discrete event simulation was developed to project outcomes associated with different service delivery patterns. Evidence‐ based outcomes were associated with dental health aide activities, and projected indicators (DMFT, F+ST, T‐health, SiC, CPI, ECC) were proxy for oral health outcomes. Model runs representing the planned program implementation, a more intensive staffing scenario, and a more robust prevention scenario, generated 20‐year projections of clinical indicators; graphs and tallies were analyzed for trends and differences. Results: Outcomes associated with alternative patterns of service delivery indicate there is potential for substantial improvement in clinical outcomes with modest program changes. Not all segments of the population derive equal benefit when program variables are altered. Children benefit more from increased prevention, while adults benefit more from intensive staffing. Conclusions: Evidence‐ based simulation is a useful tool to analyze the impact of changing program variables on program outcome measures. This simulation informs dental managers of the clinical outcomes associated with policy and service delivery variables. Simulation tools can assist public health managers in analyzing and understanding the relationship between their policy decisions and long‐term clinical outcomes.The Ford Foundation

From flux to dust mass: Does the grain-temperature distribution matter for estimates of cold dust masses in supernova remnants?

The amount of dust estimated from infrared to sub-millimetre (submm) observations strongly depends on assumptions of different grain sizes, compositions and optical properties. Here we use a simple model of thermal emission from cold silicate/carbon dust at a range of dust grain temperatures and fit the spectral energy distribution (SED) of the Crab Nebula as a test. This can lower the derived dust mass for the Crab by ~50% and 30-40% for astronomical silicates and amorphous carbon grains compared to recently published values (0.25M_sun -> 0.12M_sun and 0.12M_sun -> 0.072M_sun, respectively), but the implied dust mass can also increase by as much as almost a factor of six (0.25M_sun -> 1.14M_sun and 0.12M_sun -> 0.71M_sun) depending on assumptions regarding the sizes/temperatures of the coldest grains. The latter values are clearly unrealistic due to the expected metal budget, though. Furthermore, we show by a simple numerical experiment that if a cold-dust component does have a grain-temperature distribution, it is almost unavoidable that a two-temperature fit will yield an incorrect dust mass estimate. But we conclude that grain temperatures is not a greater uncertainty than the often poorly constrained emissivities (i.e., material properties) of cosmic dust, although there is clearly a need for improved dust emission models. The greatest complication associated with deriving dust masses still arises in the uncertainty in the dust composition.Comment: 13 pages, 7 figures, to appear in MNRA
