Dairy Food Consumption, Production, and Policy in Japan, August 2005

We explore and investigate Japanese dairy markets. We first provide an overview of consumer demand and how it evolved after World War II. Using historical data and econometric estimates of Japanese dairy demand, we identify economic, cultural, and demographic forces that have been shaping consumption patterns. Then we summarize the characteristics of Japanese milk production and dairy processing and policies affecting them. We next describe the import regime and trade flows in dairy products. The analysis of the regulatory system of the dairy sector shows how its incentive structure affects the long-term prospects of various segments of the industry. The paper concludes with policy recommendations of how to reform the Japanese dairy sector.

LSTA Five Year Plan 2003-2007, 2007

The Iowa Commission of Libraries, the State Library’s governing board, convened the Library Services Task Force in August 2000. This group consisted of 46 Iowans from across the state, including librarians from all types of libraries, library trustees, legislators, members of Iowa Regional Library system (now called Library Service Areas) and Area Education Agencies, and citizens. Their mission was to make recommendations to the Commission on positioning libraries to effectively and efficiently meet the future needs of Iowans. Needs and expectations of Iowa Library customers and funding authorities were identified and examined by the Task Force, and are reflected in its recommendations. The Commission received the Task Force recommendations in December 2000, carefully studied them, solicited input from the Iowa library community, and with a few changes, forwarded the recommendations to the Governor and the Iowa General Assembly. These recommendations are now known as Iowa Commission of Libraries priorities and serve as a blueprint for future development of the Iowa library system. A second need assessment was conducted in 2001 as part of the process to formulate the joint Library Service Area – State Library Plan of Service 2003-2005. Biennial development of this plan is mandated by the Code of Iowa. In 2001, Library Service Area and Library Development staff from the State Library chose to completely revamp this plan, and used the process outlined in the The New Planning for Results by Sandra Nelson (the Public Library Association planning model) to do so. The group conducted a strengths/weaknesses/opportunities/threat analysis of the Iowa library situation, identified needs and put them in priority order, and identified service responses. Needs identified by the Library Services Task Force were similar to those identified by the Library Service Area and Library Development staff group. These needs were further analyzed and documented by State Library staff during the development of the LSTA plan. Sources consulted are identified in the text of the LSTA plan and/or listed at the close of this document. The text of the Library Services Task Force report and the documents created during the development of the Plan of Service 2003-2005 are cited in the appendix to this document.

A Comparison of Mobile Scanning to a Total Station Survey at the I-35 and IA 92 Interchange in Warren County, Iowa, August 15, 2012

The purpose of this project was to investigate the potential for collecting and using data from mobile terrestrial laser scanning (MTLS) technology that would reduce the need for traditional survey methods for the development of highway improvement projects at the Iowa Department of Transportation (Iowa DOT). The primary interest in investigating mobile scanning technology is to minimize the exposure of field surveyors to dangerous high volume traffic situations. Issues investigated were cost, timeframe, accuracy, contracting specifications, data capture extents, data extraction capabilities and data storage issues associated with mobile scanning. The project area selected for evaluation was the I-35/IA 92 interchange in Warren County, Iowa. This project covers approximately one mile of I-35, one mile of IA 92, 4 interchange ramps, and bridges within these limits. Delivered LAS and image files for this project totaled almost 31GB. There is nearly a 6-fold increase in the size of the scan data after post-processing. Camera data, when enabled, produced approximately 900MB of imagery data per mile using a 2- camera, 5 megapixel system. A comparison was done between 1823 points on the pavement that were surveyed by Iowa DOT staff using a total station and the same points generated through the MTLS process. The data acquired through the MTLS and data processing met the Iowa DOT specifications for engineering survey. A list of benefits and challenges is included in the detailed report. With the success of this project, it is anticipate[d] that additional projects will be scanned for the Iowa DOT for use in the development of highway improvement projects.

Work Zone Simulation Model, 1999

To support the analysis of driver behavior at rural freeway work zone lane closure merge points, Center for Transportation Research and Education staff collected traffic data at merge areas using video image processing technology. The collection of data and the calculation of the capacity of lane closures are reported in a companion report, "Traffic Management Strategies for Merge Areas in Rural Interstate Work Zones". These data are used in the work reported in this document and are used to calibrate a microscopic simulation model of a typical, Iowa rural freeway lane closure. The model developed is a high fidelity computer simulation with an animation interface. It simulates traffic operations at a work zone lane closure. This model enables traffic engineers to visually demonstrate the forecasted delay that is likely to result when freeway reconstruction makes it necessary to close freeway lanes. Further, the model is also sensitive to variations in driver behavior and is used to test the impact of slow moving vehicles and other driver behaviors. This report consists of two parts. The first part describes the development of the work zone simulation model. The simulation analysis is calibrated and verified through data collected at a work zone in Interstate Highway 80 in Scott County, Iowa. The second part is a user's manual for the simulation model, which is provided to assist users with its set up and operation. No prior computer programming skills are required to use the simulation model.
