2007 Greenhouse Gas Emissions from Selected Iowa Source Categories

The Department’s 2007 Greenhouse Gas Inventory is a refinement of previous statewide inventories. It is a bottom-up inventory of two sectors – fossil fuel combustion at federally-recognized major sources of air pollution and fossil fuel combustion and ethanol fermentation at dry mill ethanol plants. This is the first bottomup greenhouse gas inventory conducted for Iowa and the first bottom-up greenhouse gas inventory of ethanol plants in the nation that the Department is aware of. In a bottom-up inventory, facility-specific activity data is used to calculate emissions. In a top-down inventory, aggregate activity data is used to calculate emissions. For example, this bottom-up inventory calculates greenhouse gas emissions from the fossil fuel combustion at each individual facility instead of using the total amount of fossil fuel combusted state-wide, which would be a top-down inventory method. The advantage to a bottom-up inventory is that the calculations are more accurate than a top-down inventory. However, because the two methods differ, the results from a bottom-up inventory are not directly comparable to a top-down inventory.

Evalution of Hot Mix Asphalt Moisture Sensitivity Using the Nottingham Asphalt Test Equipment, July 2005

Moisture sensitivity of Hot Mix Asphalt (HMA) mixtures, generally called stripping, is a major form of distress in asphalt concrete pavement. It is characterized by the loss of adhesive bond between the asphalt binder and the aggregate (a failure of the bonding of the binder to the aggregate) or by a softening of the cohesive bonds within the asphalt binder (a failure within the binder itself), both of which are due to the action of loading under traffic in the presence of moisture. The evaluation of HMA moisture sensitivity has been divided into two categories: visual inspection test and mechanical test. However, most of them have been developed in pre-Superpave mix design. This research was undertaken to develop a protocol for evaluating the moisture sensitivity potential of HMA mixtures using the Nottingham Asphalt Tester (NAT). The mechanisms of HMA moisture sensitivity were reviewed and the test protocols using the NAT were developed. Different types of blends as moisture-sensitive groups and non-moisture-sensitive groups were used to evaluate the potential of the proposed test. The test results were analyzed with three parameters based on performance character: the retained flow number depending on critical permanent deformation failure (RFNP), the retained flow number depending on cohesion failure (RFNC), and energy ratio (ER). Analysis based on energy ratio of elastic strain (EREE ) at flow number of cohesion failure (FNC) has higher potential to evaluate the HMA moisture sensitivity than other parameters. If the measurement error in data-acquisition process is removed, analyses based on RFNP and RFNC would also have high potential to evaluate the HMA moisture sensitivity. The vacuum pressure saturation used in AASHTO T 283 and proposed test has a risk to damage specimen before the load applying.

Iowa Adult Basic Education Program Benchmark Objective for Program Year, 2002

The benchmark objectives for Program Year 2002 are designed to improve Iowa's basic skills literacy program in those instructional programs, educational functioning levels, and follow-up categories which did not achieve the negotiated benchmark levels for Program Year 2001. The instructional programs, educational functioning levels and follow-up categories in which the attained benchmarks met or exceeded the negotiated benchmarks for Program Year 2001 should not be allowed to fall below the Program Year 2001 levels for Program Year 2002.

The Soil and Water Assessment Tool:Historical Development, Applications, and Future Research Directions, 2007

The Soil and Water Assessment Tool (SWAT) model is a continuation of nearly 30 years of modeling efforts conducted by the U.S. Department of Agriculture (USDA), Agricultural Research Service. SWAT has gained international acceptance as a robust interdisciplinary watershed modeling tool, as evidenced by international SWAT conferences, hundreds of SWAT-related papers presented at numerous scientific meetings, and dozens of articles published in peer-reviewed journals. The model has also been adopted as part of the U.S. Environmental Protection Agency’s BASINS (Better Assessment Science Integrating Point & Nonpoint Sources) software package and is being used by many U.S. federal and state agencies, including the USDA within the Conservation Effects Assessment Project. At present, over 250 peer-reviewed, published articles have been identified that report SWAT applications, reviews of SWAT components, or other research that includes SWAT. Many of these peer-reviewed articles are summarized here according to relevant application categories such as streamflow calibration and related hydrologic analyses, climate change impacts on hydrology, pollutant load assessments, comparisons with other models, and sensitivity analyses and calibration techniques. Strengths and weaknesses of the model are presented, and recommended research needs for SWAT are provided.

Final Report: 2007 Alzheimer's Disease Task Force, January 2008

Following an overview of the history of the task force and background information on Alzheimer’s disease, the report is divided into four sections. These sections correspond to the delineation of four subcommittees into which task force members were divided. It should be noted that the term “Alzheimer’s Disease” is used to encompass not only Alzheimer’s disease but also additional brain disorders such as vascular dementia, mixed dementia, mild cognitive impairment, dementia with Lewy bodies, and other types of dementia. Interspersed throughout the report are verbatim comments received from Iowans who responded to on-line surveys about how Alzheimer’s disease has affected their lives. Their words poignantly give voice to the emotions, frustrations, and hopes of Iowans who are personally experiencing the impact of Alzheimer’s disease. The Report includes 22 recommendations to the Iowa General Assembly designed to improve the availability and quality of services for people with dementia, their caregivers, and their families. The recommendations fall into four categories; a) Education and Training; b) Services and Housing; c) Wellness and Disease Management; and, d) Funding and Reimbursement.

Iowa Gender Wage Equity Study, 2008

In 1993, Iowa Workforce Development (then the Department of Employment Services) conducted a survey to determine if there was a gender gap in wages paid. The results of that survey indicated that females were paid 68 cents for every dollar paid to males. Another study was conducted in 1999 which found that females made approximately 73 cents for every dollar made by males in Iowa. These calculations took into account the average number of hours respondents worked weekly. In January 2008, Iowa Workforce Development (IWD) was contacted by the Iowa Commission on the Status of Women (ICSW) to request that IWD conduct research to update the 1999 gender wage equity study to determine if the wage disparity between males and females has changed since the 1999 study. This study was completed by IWD using 2007/2008 Laborshed data consisting of responses from 5,669 employed respondents. Of the respondents, 59.6 percent (3,379) were female, 40.3 percent (2,285) were male, and 0.1 percent (5) refused to identify their gender. Statewide sampling was provided by the University of Northern Iowa’s Institute for Decision Making based on the population per ZIP code. The results of the survey show that females who are paid an hourly wage earn 21.8 percent (78.2 cents for every dollar) less than males earn and females who are salaried earn 21.6 percent less than males. Additional survey results detail the occupational categories, industries and the education and experience levels. All of these characteristics contribute to the disparity.
