Rice Consumption in the United States: New Evidence from Food Consumption Surveys, July 2005

Evidence from recent U.S. food consumption surveys provides new information on the distribution of rice consumption, the characteristics of rice consumers, and the diets of people who consume rice. Recently available data from nationally representative surveys of food consumed by individuals in the United States allowed comparison of consumption today (2001-02) with consumption in the mid-1990s. Data come from the Continuing Survey of Food Intakes by Individuals (1994-96) and the National Health and Nutrition Examination Survey (2001-02). Rice is consumed by a significant portion of the U.S. adult population. In 2001-02, over 18 percent (18.2 percent) of adults reported eating at least half a serving of white or brown rice in one day of observed intake. This share was slightly higher than that of 1994-96 (17.4 percent). Compared with others, individuals who consumed at least half a serving of white or brown rice in the observed day of intake consumed a smaller share of calories per day from fat and saturated fat; less discretionary fat or added sugar; and more fiber, dietary folate, fruit, vegetables, and enriched grains. Consumers eating rice were more likely to eat a diet that included choices of foods consistent with the 2005 U.S. Dietary Guidelines.

What can the United States learn from Spain's Pork Sector? Implications from a Comparative Economic Analysis, September 2005

This study provides a comparative economic analysis of the primary production of pork and its marketing channel in Spain and the United States. The focus on Spain is due to the profound growth and transformation of its pork sector over the last 20 years, compared with other major players in the world market for pig meat. The analysis reveals a number of similar characteristics but also important differences between the two countries. The significant expansion of Spain’s pork production sector stemmed from a number of factors that apply, to a relatively large extent, to some U.S. states (in particular, North Carolina) but do not apply to the U.S. pork production sector as a whole. This implies that it is unlikely that the U.S. pork production sector as a whole will mimic an expansion driven by the same type of factors in the future. Likewise, it seems highly unlikely that the U.S. consumption of pig meat will expand in the future based on the same driving forces behind the sharp increase in Spain’s domestic demand for pig meat over the last 20 years. The analysis also indicates that Spanish pig producers are currently being subjected to more stringent environmental and animal welfare regulations than their U.S. counterparts and that these regulations are becoming increasingly more restrictive. It would not be surprising to see similar trends emerging in the United States, leading to a substantially more restrictive regulatory environment for U.S. hog producers.

EU Enlargement and Technology Transfer to New Member States, November 2005

The European Union (EU) accomplished its biggest enlargement process in 2004 in terms of the number of countries, area, and population. This study focuses on the impact of enlargement, the resulting technology transfer on the grain sectors of the New Member States (NMS), and the consequent welfare implications. The study finds that EU enlargement has important implications for the EU and the NMS, but its impact on the world grain markets is minimal. The results show that producers in the NMS gain from accession because of higher prices, whereas consumers in most NMS face a welfare loss. Incorporating technology transfer into the accession increases the welfare gain of producers despite falling prices because of the larger supply shift. The loss of welfare for consumers in most NMS is lower in this case because of the decline in grain prices.

Economic Aspects of Agricultural and Food Biosecurity in the United States, March 2007

Concerns about biosecurity in the food system raise a variety of issues about how the system is presently organized, why it might be vulnerable, what one could reasonably do to better secure it, and the costs of doing so. After presenting some facts about US agriculture and food, this paper considers three economic aspects of the general problem. One is the global problem, or the way biosecurity measures can affect how countries relate to each other and the global consequences that result. Another is how to best manage the immediate aftermath of a realized threat in order to minimize damage. The third is how to seek to prevent realization of the threat. Some policy alternatives are also presented.

The Growth and Direction of the Biodiesel Industry in the United States, 2007

The biodiesel industry in the United States has realized significant growth over the past decade through large increases in annual production and production capacity and a transition from smaller batch plants to larger-scale continuous producers. The larger, continuous-flow plants provide operating cost advantages over the smaller batch plants through their ability to capture co-products and reuse certain components in the production process. This paper uses a simple capital budgeting model developed by the authors along with production data supplied by industry sources to estimate production costs, return-on-investment levels, and break-even conditions for two common plant sizes (30 and 60 million gallon annual capacities) over a range of biodiesel and feedstock price levels. The analysis shows that the larger plant realizes returns to scale in both labor and capital costs, enabling the larger plant to pay up to $0.015 more per pound for the feedstock to achieve equivalent return levels as the smaller plant under the same conditions. The paper contributes to the growing literature on the biodiesel industry by using the most current conversion rates for the production technology and current price levels to estimate biodiesel production costs and potential plant performance, providing a useful follow-up to previous studies.

Iowa "50 States Project": A Review of the 1983 Code for Sexuality Discrimination, February 1984

The "50 States Project" is the name given to President Ronald D. Reagan;s 1981 pledge to encourage the fifty governors to initiate individual state projects to review their state Codes for unequal treatment of persons based upon sex. We believe that Iowa is the first state to complete this project. Project efforts in Iowa began in June of 1981, when the Governor Robert D. ray appointed Dr. Patricia L. Geadelmann, Chairperson on the Iowa commission on the Status of Women, as Iowa's 50 State Project representative. A 50 States planning committee was formed consisting of members from the Governor Ray's staff, the Iowa Commission on the Status of Women, and the Iowa Legislature. Various alternatives for reviewing the Iowa code and the Iowa Administrative Rules were studied and recommendations of the group were reported to Governor Terry E. Branstad prior to his inauguration.

Wind Loads on Dynamic Message Cabinets and Behavior of Supporting Trusses, TR-612, 2013

Large Dynamic Message Signs (DMSs) have been increasingly used on freeways, expressways and major arterials to better manage the traffic flow by providing accurate and timely information to drivers. Overhead truss structures are typically employed to support those DMSs allowing them to provide wider display to more lanes. In recent years, there is increasing evidence that the truss structures supporting these large and heavy signs are subjected to much more complex loadings than are typically accounted for in the codified design procedures. Consequently, some of these structures have required frequent inspections, retrofitting, and even premature replacement. Two manufacturing processes are primarily utilized on truss structures - welding and bolting. Recently, cracks at welding toes were reported for the structures employed in some states. Extremely large loads (e.g., due to high winds) could cause brittle fractures, and cyclic vibration (e.g., due to diurnal variation in temperature or due to oscillations in the wind force induced by vortex shedding behind the DMS) may lead to fatigue damage, as these are two major failures for the metallic material. Wind and strain resulting from temperature changes are the main loads that affect the structures during their lifetime. The American Association of State Highway and Transportation Officials (AASHTO) Specification defines the limit loads in dead load, wind load, ice load, and fatigue design for natural wind gust and truck-induced gust. The objectives of this study are to investigate wind and thermal effects in the bridge type overhead DMS truss structures and improve the current design specifications (e.g., for thermal design). In order to accomplish the objective, it is necessary to study structural behavior and detailed strain-stress of the truss structures caused by wind load on the DMS cabinet and thermal load on the truss supporting the DMS cabinet. The study is divided into two parts. The Computational Fluid Dynamics (CFD) component and part of the structural analysis component of the study were conducted at the University of Iowa while the field study and related structural analysis computations were conducted at the Iowa State University. The CFD simulations were used to determine the air-induced forces (wind loads) on the DMS cabinets and the finite element analysis was used to determine the response of the supporting trusses to these pressure forces. The field observation portion consisted of short-term monitoring of several DMS Cabinet/Trusses and long-term monitoring of one DMS Cabinet/Truss. The short-term monitoring was a single (or two) day event in which several message sign panel/trusses were tested. The long-term monitoring field study extended over several months. Analysis of the data focused on trying to identify important behaviors under both ambient and truck induced winds and the effect of daily temperature changes. Results of the CFD investigation, field experiments and structural analysis of the wind induced forces on the DMS cabinets and their effect on the supporting trusses showed that the passage of trucks cannot be responsible for the problems observed to develop at trusses supporting DMS cabinets. Rather the data pointed toward the important effect of the thermal load induced by cyclic (diurnal) variations of the temperature. Thermal influence is not discussed in the specification, either in limit load or fatigue design. Although the frequency of the thermal load is low, results showed that when temperature range is large the restress range would be significant to the structure, especially near welding areas where stress concentrations may occur. Moreover stress amplitude and range are the primary parameters for brittle fracture and fatigue life estimation. Long-term field monitoring of one of the overhead truss structures in Iowa was used as the research baseline to estimate the effects of diurnal temperature changes to fatigue damage. The evaluation of the collected data is an important approach for understanding the structural behavior and for the advancement of future code provisions. Finite element modeling was developed to estimate the strain and stress magnitudes, which were compared with the field monitoring data. Fatigue life of the truss structures was also estimated based on AASHTO specifications and the numerical modeling. The main conclusion of the study is that thermal induced fatigue damage of the truss structures supporting DMS cabinets is likely a significant contributing cause for the cracks observed to develop at such structures. Other probable causes for fatigue damage not investigated in this study are the cyclic oscillations of the total wind load associated with the vortex shedding behind the DMS cabinet at high wind conditions and fabrication tolerances and induced stresses due to fitting of tube to tube connections.

A Comparative Study: Service Animals and Emotional Support Animals under the Fair Housing Act and the Americans with Disabilities Act & An Overview of Assistance Animal Laws of Select States, April 18, 2010

The Americans with Disabilities Act (ADA) and the Fair Housing Act (FHA) prohibit discrimination on the basis of disability and govern the use of service or emotional support animals in places where pets may not be permitted. However, courts have been struggling with how to define and treat animals that qualify for protection under each law. This has created confusion as to what rights and duties are owed disabled persons and the animals that live with or accompany them. This essay attempts to clarify these two federal laws with regard to service or emotional support animals and the differing parties‘ rights and interests. It also includes an overview of select state laws that govern assistance animals of all types and our recommendations for enhancing the Iowa Civil Rights Act.
