Public Perceptions of the Midwest’s Pavements - Minnesota - Phase I (Winter Ride)

The Minnesota Winter Ride Survey was designed to gauge the extent to which motorists were tolerant of the rougher ride of pavements on rural two-lane highways in the winter. Survey objectives, therefore, were centered around this focal question of winter ride tolerance. A telephone survey was conducted during the first quarter of the year (January 15 to March 15, 1997) by the Wisconsin Survey Research Laboratory (WSRL), which simultaneously conducted a similar survey in Wisconsin. Random digit dial samples were drawn for both states according to accepted sampling procedure. The survey data set provided by WSRL included 417 respondents. Analysis of the survey responses, performed by Marquette University, yielded insights into the sample composition and relationships between respondents’ perception/tolerance and their driving and demographic characteristics. In terms of demographics, the sample was evenly split male versus female, with two-thirds of the respondents in the 21-49 age range. Almost half were lifetime residents of Minnesota, and one-third had a college degree or beyond. A majority drove cars, as opposed to minivans, trucks, etc., and very few of the respondents rated the roughness of their vehicle’s ride as less than average. Minnesota Winter Ride Survey findings, on the whole, were reasonably consistent. Minnesota drivers who had noticed a change in the pavement’s ride since the beginning of winter were largely more tolerant of the rough ride than they would be the rest of the year. Based on the analysis, it was apparent that the perception and tolerance of the survey respondents was influenced by particular driving and demographic characteristics

National report on biochemical indicators of diet and nutrition in the U.S. population

The National Report on Biochemical Indicators of Diet and Nutrition in the U.S. Population is a series of publications that provide ongoing assessment of the U.S. population's nutrition status by measuring blood and urine levels of diet-and-nutrition biochemical indicators. This is the second report in this series. The Centers for Disease Control and Prevention's (CDC) Division of Laboratory Sciences at the National Center for Environmental Health (NCEH/DLS) conducted the laboratory analyses for 58 biochemical indicators presented in this 2012 report. CDC measured these indicators in specimens from a representative sample of the U.S. population during all or part of the four-year period from 2003 through 2006. Where available, data are also presented on changes of biochemical indicator levels over time since 1999. Similarly, data are also presented on the prevalence of low or high biochemical indicator levels during 2003-2006, and on changes in the prevalence over time since 1999. The first report of this series was published in July 2008 and it contains information on 27 biochemical indicators from all or part of the four-year period from 1999 through 2002. Both reports can be accessed online: http://www.cdc.gov/nutritionreport. The specimens for the Second Nutrition Report were collected by CDC's National Health and Nutrition Examination Survey (NHANES), which is conducted by the National Center for Health Statistics (NCHS). NHANES is a series of surveys designed to collect data on the health and nutrition status of the U.S. population. This report covers one important facet in the assessment of nutrition status of the U.S. population: biochemical measurements. Other nutrition-related aspects from NHANES, such as dietary intake, supplement usage, hematologic measurements, and anthropometric body measurements are not covered

Storms, Floods, and Debris Flows in Southern California and Arizona, 1978 and 1980: Proceedings of a Symposium, September 17-18,1980

Following the floods of 1978 and 1980 in southern California and Arizona a symposium was convened at the California Institute of Technology in September 1980 to document the significant events of these floods and to exchange information and evaluations. The symposium laid the groundwork for a volume of proceedings, which serves as a compact permanent source of information on these floods for not only local readers but national readers as well. Special attention is given in the proceedings to documenting problems--some engineering, some institutional--and to drawing conclusions and making recommendations for research. The papers included are not intended to be research papers or to replace the much more detailed reports of individual agencies. The emphasis was on preparing and presenting the papers soon after the event in such a way as to emphasize the regional nature of floods and flood control problems. The proceedings are organized into several sections, with 35 papers altogether. Following the overview and summary, Section 2, STORM METEOROLOGY, which consists of four papers, describes the long-range weather patterns that affect the southwestern United States; the relationship of these patterns to sea surface temperatures in the North Pacific Ocean; the short-term synoptic meteorology of the storms under consideration, showing the importance of multiple storm sequences; and statistical analyses of return periods, based on historical data, for precipitation at a point. Section 3, DOWNSTREAM RIVER FLOODING, consisting of nine papers, gives an overview of the floods on the larger rivers, how the flood control works responded, and what damages occurred. Section 4, UPLAND FLOODS AND SEDIMENT TRANSPORT (five papers), focuses on the unique aspects of sedimentation in regional floods. Section 5, LANDSLIDES, with four papers, explains the problems of landslides, both large and small, that were triggered by the prolonged periods of heavy rainfall. Section 6, CASE STUDIES OF ENGINEERING PROBLEMS (four papers), gives detailed analyses of three particular engineering problems: the failure of levees on the San Jacinto River, the uncontrolled filling of Lake Elsinore to damaging stages, and the severe streambed scour threatening to undermine the Interstate 10 highway bridge over the Salt River at Phoenix, Arizona. The experiences and analyses described in these papers should be useful to engineers who deal with similar structures and situations in the future. Section 7, EFFECTS ON THE SHORELINE, consisting of two papers, illustrates the damaging effects of the high storm waves and high tides that occurred in 1978 and 1980. Beach profiles shifted very rapidly, with sand being moved temporarily offshore, which exposed many shoreline structures to direct wave attack, causing severe damages. Section 8, POLICIES FOR FLOOD CONTROL AND HAZARD MITIGATION (six papers),focuses on institutional issues. Four of these papers advocate a strong new emphasis on hazard mitigation, better flood warning systems, and other nonstructural approaches as part of the mix of society's activities to deal with floods. About 300 people participated in the symposium, and many contributed to the questions and discussion. In the closing session there was a panel discussion by Russell Campbell, Engineering Geologist with the U.S. Geological Survey; John F. Kennedy, Director of the Iowa Institute on Hydraulic Research at the University of Iowa and member of the Committee on Natural Disasters of the National Research Council; Dale Peterson, Director of Community Services with the Federal Emergency Management Agency (FEMA) in San Francisco; and Richard Wainer, Los Angeles City Engineer's Office in Van Nuys. The writer served as moderator. Since it was not feasible to digest and record all of these discussions, I am attempting in this summary to capture the main conclusions and issues.* Nonetheless, the following conclusions and recommendations are solely the responsibility of the author and do not necessarily represent a consensus by the participants at the symposium. For the record it should be noted that the following papers included in the proceedings were not presented at the symposium: "Geotechnical Origin and Repair of the Bluebird Canyon Landslide, Laguna Beach, California" by Beach Leighton and "Levee Failures and Distress, San Jacinto River Levee and Bautista Creek Channel, Riverside County, Santa Ana River Basin, California" by Joe Sciandrone, Ted Albrecht, Jr., Richard Davidson, Jacob Douma, Dave Bamer, Charles Hooppaw, and A1 Robles, Jr. The latter paper is a shortened version of the official Corps of Engineers report on the San Jacinto River levee failure , which was not available in time for presentation at the conference. Numerous brief discussions at the symposium are gratefully acknowledged, although very few are included in the proceedings
