A Case Study of China’s Commercial Pork Value Chain, August 2005

In China, with the cost of improved technology rising, surplus labor shrinking, and demand for food quality and safety increasing, it will be just a matter of time before the country’s hog production sector will be commercialized like that of developed countries. However, even if China’s cost of production converges to international levels, as shown in this case study, China may continue to retain some competitive advantage because of the labor-intensive nature of the marketing services involved in hog processing and meat distribution. The supply of variety meats offers the most promising market opportunity for foreign suppliers in China. The market may open further if the tariff rate for variety meats is reduced from 20% and harmonized with the pork muscle meat rate of 12%, and if the value-added tax of 13% is applied equally to both imported and domestic products. The fast-growing Western-style family restaurant and higher-end dining sector is another market opportunity for high-quality imported pork.

Improving Transition Outcomes-Value of IVRS Partnership, 2004

Iowa Vocational Rehabilitation Services, a Division of the State of Iowa Department of Education, in partnership with six other state agencies, applied for and was awarded funding for “Improving Transition Outcomes for Youth with Disabilities Through the Use of intermediaries.” This Innovative State Alignment Grant is funded by the Department of Labor, Office of Disability Employment Policy. For clarity and brevity, the Iowa team chose to use “Improving Transition Outcomes” as the project name, thus providing the acronym ITO. Grant funding began October 1, 2003 with the possibility of renewal for five years.

Iowa Brownfield Reuse Guide, September 15, 2008

Brownfield sites come in all shapes and sizes, from vacated industrial sites to a single building plagued with asbestos materials. Brownfield sites are found in both urban and rural settings and present challenges that make the cleanup and redevelopment of these sites unique as compared with other real estate projects.

Medicaid Value Management Program SFY 2008 Report Executive Summary, 2007

In SFY 2007 the Medicaid Value Management program was developed under the direction of the Iowa Medicaid Director to establish a more comprehensive approach for improving the quality and value of medical services to Iowa Medicaid members. Medical services Unit provided the leadership for the program development and implementation.

Medicaid Value Management Program SFY 2008 Report Executive Summary, 2007

In June, 2007, the Commonwealth Fund released a report entitled, “Aiming Higher: Results from a State Scorecard on Health System Performance.” The report ranked states’ health care performance based upon four areas: access, quality, potentially avoidable use of hospitals and costs of care, and healthy lives. Iowa was ranked second overall and was the only state to rank in the top 25 percent on each of the four measures.1 Coupling the HEDIS measures and CAHPS survey results with the Commonwealth report outcomes provides additional information for determining how the state performs with regard to the health care system, in general, and the Medicaid program specifically. For the past five years the results of eight outcome measures encompassing children and adults, and preventive, chronic and acute care have been reported by the University of Iowa Public Policy Center (PPC). The PPC is the independent evaluator for the Medicaid managed care programs and assists the state in an effort to understand the process of care within the Medicaid program. Seven of the eight measures are recommended by the Centers for Medicare and Medicaid, while the eighth, annual dental visit, is used in recognition of the challenges found in providing dental care to Medicaid‐enrolled children and adults.

The Value of the County Engineer: Strategies to Expand the Shrinking Employment Pool, HR-338, 1993

The first phase of this research involved an effort to identify the issues relevant to gaining a better understanding of the County Engineering profession. A related objective was to develop strategies to attract responsible, motivated and committed professionals to pursue County Engineering positions. In an era where a large percentage of County Engineers are reaching retirement age, the shrinking employment pool may eventually jeopardize the quality of secondary road systems not only in Iowa, but nationwide. As we move toward the 21st century, in an era of declining resources, it is likely that professional staff members in charge of secondary roads will find themselves working with less flexible budgets for the construction and maintenance of roads and bridges. It was important to understand the challenges presented to them, and the degree to which those challenges will demand greater expertise in prioritizing resource allocations for the rehabilitation and maintenance of the 10 million miles of county roads nationwide. Only after understanding what a county engineer is and what this person does will it become feasible for the profession to begin "selling itself", i.e., attracting a new generation of County Engineers. Reaching this objective involved examining the responsibilities, goals, and, sometimes, the frustrations experienced by those persons in charge of secondary road systems in the nine states that agreed to participate in the study. The second phase of this research involved addressing ways to counter the problems associated with the exodus of County Engineers who are reaching retirement age. Many of the questions asked of participants asked them to compare the advantages and disadvantages of public sector work with the private sector. Based on interviews with nearly 50 County Engineers and feedback from 268 who returned surveys for the research, issues relevant to the profession were analyzed and recommendations were made to the profession as it prepares to attract a new generation. It was concluded that both State and Regional Associations for County Engineers, and the National Association of County Engineers are most well-situated to present opportunities for continued professional development. This factor is appealing for those who are interested in competitive advantages as professionals. While salaries in the public sector may not be able to effectively compete with those offered by the private sector, it was concluded that this is only one factor of concern to those who are in the business of "public service". It was concluded, however, that Boards of Supervisors and their equivalents in other states will need to more clearly understand the value of the contributions made by County Engineers. Then the selling points the profession can hope to capitalize on can focus on the strength of state organizations and a strong national organization that act as clearinghouses of information and advocates for the profession, as well as anchors that provide opportunities for staying current on issues and technologies.

Reuse of Lime Sludge from Water Softening and Coal Combustion Byproducts, TR-459, 2004

Disposal of lime sludge remains a major challenge to cities in the Midwest. Disposal of lime sludge from water softening adds about 7-10% to the cost of water treatment. Having effective and safe options is essential for future compliance with the regulations of the State of Iowa and within budget restrictions. Dewatering and drying are essential to all reuse applications as this affects transportation costs and utility. Feasibility tests were conducted on some promising applications like SOx control in power generation facilities that burn coal, replacement of limestone as an ingredient in portland cement production, dust control on gravel roads, neutralization of industrial wastewater pH, and combination with fly ash or cement in construction fill applications. A detailed report and analysis of the construction fills application is presented in the second half of the report. A brief discussion of the results directly follows.

Applications for Reuse of Lime Sludge from Water Softening, TR-535, 2005

Lime sludge, an inert material mostly composed of calcium carbonate, is the result of softening hard water for distribution as drinking water. A large city such as Des Moines, Iowa, produces about 30,700 tons of lime sludge (dry weight basis) annually (Jones et al., 2005). Eight Iowa cities representing, according to the United States (U.S.) Census Bureau, 23% of the state’s population of 3 million, were surveyed. They estimated that they collectively produce 64,470 tons of lime sludge (dry weight basis) per year, and they currently have 371,800 tons (dry weight basis) stockpiled. Recently, the Iowa Department of Natural Resources directed those cities using lime softening in drinking water treatment to stop digging new lagoons to dispose of lime sludge. Five Iowa cities with stockpiles of lime sludge funded this research. The research goal was to find useful and economical alternatives for the use of lime sludge. Feasibility studies tested the efficacy of using lime sludge in cement production, power plant SOx treatment, dust control on gravel roads, wastewater neutralization, and in-fill materials for road construction. Applications using lime sludge in cement production, power plant SOx treatment, and wastewater neutralization, and as a fill material for road construction showed positive results, but the dust control application did not. Since the fill material application showed the most promise in accomplishing the project’s goal within the time limits of this research project, it was chosen for further investigation. Lime sludge is classified as inorganic silt with low plasticity. Since it only has an unconfined compressive strength of approximately 110 kPa, mixtures with fly ash and cement were developed to obtain higher strengths. When fly ash was added at a rate of 50% of the dry weight of the lime sludge, the unconfined strength increased to 1600 kPa. Further, friction angles and California Bearing Ratios were higher than those published for soils of the same classification. However, the mixtures do not perform well in durability tests. The mixtures tested did not survive 12 cycles of freezing and thawing and wetting and drying without excessive mass and volume loss. Thus, these mixtures must be placed at depths below the freezing line in the soil profile. The results demonstrated that chemically stabilized lime sludge is able to contribute bulk volume to embankments in road construction projects.
