  4. Joel Stebbins and Light Pollution

    NASA Astrophysics Data System (ADS)

    Garstang, R. H.

    2002-05-01

    Joel Stebbins (1878 - 1966), Director of the Washburn Observatory of the University of Wisconsin, pioneered the use of photocells for astronomical brightness measurements. He seems to have been the first to use photocells to measure night sky brightnesses. He was a Research Associate of the Mount Wilson Observatory. During a visit to Pasadena in the winter of 1931-32 he measured the night sky brightness with a portable photometer on Palomar Mountain and at the Mount Wilson Observatory. The latter had begun to be affected by light pollution even at that early date. He does not seem to have published his results in detail, but reported them in a letter that he sent on 1932 October 5 to John A. Anderson, the Executive Officer of the Palomar Observatory Council. Donald Osterbrock recently found a copy of the letter in the Washburn Observatory archives, and kindly communicated the details to me for analysis. Stebbins' most important result was that the night sky near the North Pole at Mount Wilson was 0.38 magnitude brighter than the night sky at Palomar. He also stated that in the evening at Mount Wilson the sky at altitude 10 deg over Pasadena and Los Angeles could be as much as 5 times as bright as at the Pole. I have used my light pollution model to analyze these and other results of Stebbins. I estimate that the light emission of the cities in 1932 was about 220 lumens per capita. Using this emission I calculated the Mount Wilson sky brightness at 10 deg altitude over Pasadena and Los Angeles as about 5.4 times the brightness at the Pole, in excellent agreement with Stebbins. This light emission may be compared with 1000 lumens per capita that my earlier analyses indicated for 1970.

    2013-01-01

    Objective This study was designed to compare the Pfannenstiel versus Joel-Cohen incisions during caesarean deliveries. Material and Methods Women undergoing caesarean deliveries (n=153) were randomly assigned to the conventional Pfannenstiel or the Joel-Cohen incision. The outcome measures included postoperative pain, requirement for analgesics, operative time and other postoperative data. Results Maternal age, parity, gestational age and indications for caesarean delivery were similar across groups. Total operative time, postoperative recovery duration, time to get out of bed, to walk straight without support, to detect audible intestinal sounds and to pass gases or stools were shorter in the Joel-Cohen group. Postoperative haematocrit decreases and estimated intraoperative blood loss were similar between the two techniques. Moderate and severe pain at 6, 12 and 18 hours postoperatively was less frequent after the Joel-Cohen technique. Conclusion Joel-Cohen incision in the non-scarred abdomen may provide a faster technique for caesarean section with less postoperative pain and probably early postoperative recovery in our circumstances.

    2013-01-01

    Objective: Pfanennstiel incision is the most commonly used incision for cesarean section, but may not be the best. This study compared the modified Joel-Cohen incision with the Pfannenstiel incision to evaluate whether techniques to open the abdomen might influence operative time, and maternal and neonatal outcomes. Material and Methods: In a randomized comparative trial, 302 women with gestational age >34 weeks, requiring cesarean section, were randomly assigned to either modified Joel-Cohen incision or Pfannenstiel incision for entry into the peritoneal cavity. The primary outcome measure was total time required for performing operation and secondary outcome measures were baby extraction time, number of haemostatic procedures used in the abdominal wall, postoperative morbidity, postoperative hospital stay and neonatal outcome. Results: Mean total operative time was significantly less in the modified Joel-Cohen group as compared to the Pfannenstiel group (29.81 vs 32.67 min, p<0.0001, 95%CI=2.253 to 3.467). Time taken to deliver the baby and haemostatic procedures required during operation were also significantly less in the modified Joel-Cohen group as compared to the Pfannenstiel group. Requirement of strong analgesics was higher in the Pfannenstiel group (53.64% vs 21.85%, p<0.0001). There was no statically significant difference in the incidence of postoperative wound complications but postoperative stay in hospital was significantly less in the modified Joel-Cohen group (p=0.002). Neonatal outcomes were similar in both groups. Conclusion: The modified Joel-Cohen incision for entry into peritoneal cavity during cesarean section is associated with reduced mean total operative and baby extraction times with less postoperative pain and shorter hospital stay, which may be beneficial and cost effective.

  2. Partially supervised speaker clustering.

    PubMed

    Tang, Hao; Chu, Stephen Mingyu; Hasegawa-Johnson, Mark; Huang, Thomas S

    2012-05-01

    Content-based multimedia indexing, retrieval, and processing as well as multimedia databases demand the structuring of the media content (image, audio, video, text, etc.), one significant goal being to associate the identity of the content to the individual segments of the signals. In this paper, we specifically address the problem of speaker clustering, the task of assigning every speech utterance in an audio stream to its speaker. We offer a complete treatment to the idea of partially supervised speaker clustering, which refers to the use of our prior knowledge of speakers in general to assist the unsupervised speaker clustering process. By means of an independent training data set, we encode the prior knowledge at the various stages of the speaker clustering pipeline via 1) learning a speaker-discriminative acoustic feature transformation, 2) learning a universal speaker prior model, and 3) learning a discriminative speaker subspace, or equivalently, a speaker-discriminative distance metric. We study the directional scattering property of the Gaussian mixture model (GMM) mean supervector representation of utterances in the high-dimensional space, and advocate exploiting this property by using the cosine distance metric instead of the euclidean distance metric for speaker clustering in the GMM mean supervector space. We propose to perform discriminant analysis based on the cosine distance metric, which leads to a novel distance metric learning algorithm—linear spherical discriminant analysis (LSDA). We show that the proposed LSDA formulation can be systematically solved within the elegant graph embedding general dimensionality reduction framework. Our speaker clustering experiments on the GALE database clearly indicate that 1) our speaker clustering methods based on the GMM mean supervector representation and vector-based distance metrics outperform traditional speaker clustering methods based on the “bag of acoustic features” representation and statistical

    The Iowa Flood Information System (IFIS) is a web-based platform developed by the Iowa Flood Center (IFC) to provide access to flood inundation maps, real-time flood conditions, flood forecasts both short-term and seasonal, flood-related data, information and interactive visualizations for communities in Iowa. The key element of the system's architecture is the notion of community. Locations of the communities, those near streams and rivers, define basin boundaries. The IFIS provides community-centric watershed and river characteristics, weather (rainfall) conditions, and streamflow data and visualization tools. Interactive interfaces allow access to inundation maps for different stage and return period values, and flooding scenarios with contributions from multiple rivers. Real-time and historical data of water levels, gauge heights, and rainfall conditions are available in the IFIS by streaming data from automated IFC bridge sensors, USGS stream gauges, NEXRAD radars, and NWS forecasts. Simple 2D and 3D interactive visualizations in the IFIS make the data more understandable to general public. Users are able to filter data sources for their communities and selected rivers. The data and information on IFIS is also accessible through web services and mobile applications. The IFIS is optimized for various browsers and screen sizes to provide access through multiple platforms including tablets and mobile devices. The IFIS includes a rainfall-runoff forecast model to provide a five-day flood risk estimate for around 500 communities in Iowa. Multiple view modes in the IFIS accommodate different user types from general public to researchers and decision makers by providing different level of tools and details. River view mode allows users to visualize data from multiple IFC bridge sensors and USGS stream gauges to follow flooding condition along a river. The IFIS will help communities make better-informed decisions on the occurrence of floods, and will alert communities

    2014-06-01

    In a recent article, Joel Marks presents the amoralist argument against vivisection, or animal laboratory experimentation. He argues that ethical theories that seek to uncover some universal morality are in fact useless and unnecessary for ethical deliberations meant to determine what constitutes an appropriate action in a specific circumstance. I agree with Marks' conclusion. I too believe that vivisection is indefensible, both from a scientific and philosophical perspective. I also believe that we should become vegan (unfortunately, like the two philosophers mentioned by Marks, I too am still struggling to reduce my meat and dairy consumption). However, I am in the dark as to Marks' vision of normative deliberations in the spirit of amoralism and desirism.

  19. Flooding near Hamburg, Iowa

    NASA Image and Video Library

    2017-09-27

    NASA image acquired July 17, 2011 In mid-July 2011, more than a month after the Missouri River broke through two levees and flooded fields near Hamburg, Iowa, muddy water lingered near the city. Hamburg residents were relieved, however, that a newly built levee had spared the town from flooding. On July 17, 2011, the Advanced Land Imager (ALI) on NASA’s Earth Observing-1 (EO-1) satellite captured this natural-color image. Compared to an image acquired on June 24, flooding has apparently receded slightly in some areas. Sediment-choked water nevertheless lingers on large swaths of land. On July 13, 2011, KETV of Omaha, Nebraska, reported that a newly built, 2-mile levee designed to protect Hamburg already exceeded federal standards. The U.S. Army Corps of Engineers handed control of the levee over to city officials on July 12. In the end, the levee was expected to cost the Army Corps $6 million, and the city of Hamburg about $800,000. On July 18, 2011, the Advanced Hydrological Prediction Service reported moderate flooding along the Missouri River not far from Hamburg, Iowa. In the northwest, the river reached 24.37 feet (7.43 meters) at Nebraska City. In the southeast, the river reached 38.98 feet (11.88 meters) at Brownville, Nebraska.

  8. The "Iowa Way" revisited.

    PubMed

    Zebrowski, Patricia M; Arenas, Rick M

    2011-09-01

    This paper attempts to bridge the gap between past and present stuttering therapy approaches. Specifically, the ideas and methods of Wendell Johnson and Dean Williams are compared to current approaches used in treating mental illness and communication disorders in which there is an emphasis on focusing on what is "right" with the individual and spending less time focusing on the "disorder". There is particular emphasis on tying Johnson's and Williams' overall philosophy to modern psychological approaches rooted in "Positive Psychology", to highlight how these early ideas in stuttering therapy may help us to discover the common factors that underlie the success of several different stuttering therapy approaches, independent of the specific techniques employed. It is proposed that future research on clinical efficacy in stuttering should use focused hypotheses techniques to investigate common factors that make therapy effective across individuals and therapy approaches. The reader will be able to: (1) summarize the basic philosophy of the "Iowa" approach to stuttering as laid out by Wendell Johnson and Dean Williams; (2) describe current therapeutic techniques that incorporate "positive psychology"; (3) discuss possible common factors that influence therapy outcome that are independent of the therapeutic technique employed.

    In recent years Iowa and the U.S. Midwest has experienced both extreme drought and flood periods. With a drought in 2012 bounded by major floods in 2011 and 2013, the rapid progression from one extreme to the next is on the forefront of the public mind. Given that Iowa is a major agricultural state, extreme weather conditions can have severe socioeconomic consequences. In this research we investigate the large-scale climate processes that occurred concurrently and before a range of dry/wet and cold/hot periods to improve process understanding of these events. It is essential to understand the large-scale climate processes, as these can then provide valuable insight toward the development of long-term climate forecasts for Iowa. In this study monthly and seasonal surface temperature and precipitation over 1950-2012 across Iowa are used. Precipitation and surface temperature data are retrieved from the Parameter-elevation Regressions on Independent Slopes Model (PRISM) Climate Group at Oregon State University. The large-scale atmospheric fields are obtained from the National Center for Environmental Prediction (NCEP) / National Center for Atmospheric Research (NCAR) Reanalysis 1 Project. Precipitation is stratified according to wet, normal, and dry conditions, while temperature according to hot, average, and cold periods. Different stratification criteria based on the precipitation and temperature distributions are examined. Mean sea-level pressure and sea-surface temperature composite maps for the northern hemisphere are then produced for the wet/dry conditions, and cold/hot conditions. Further analyses include correlation, anomalies, and assessment of large-scale planetary wave activity, shedding light on the differences and similarities among the opposite weather conditions. The results of this work will highlight regional weather patterns that are related to the climate over Iowa, providing valuable insight into the mechanisms controlling the occurrence of

    Public health is an important component of veterinary medicine. In the last 10 years, there has been growing recognition of the need to increase the number of veterinarians trained in public health. The Center for Food Security and Public Health (CFSPH) at Iowa State University (ISU), College of Veterinary Medicine, received a grant from the Centers for Disease Control and Prevention (CDC) to support veterinarians working at CFSPH while pursuing the Master of Public Health degree. CFSPH and ISU administrators worked with the University of Iowa (UI) College of Public Health to establish three cooperative programs for veterinarians to earn the MPH degree. This article describes how these programs were developed and how they operate. (1) Between 2002 and 2005, CFSPH used funds provided by the CDC to support 15 veterinarians as they worked for CFSPH and toward the MPH degree. As the program grew, distance-education methods such as the Internet, Polycom videoconferencing, and the Iowa Communications Network (ICN) were incorporated. (2) A concurrent DVM/MPH degree is now offered; students can complete both degrees in four years. As of January 2008, three students have received their DVM and MPH degrees and 16 students are enrolled in the program. (3) In June 2007, the UI and ISU launched a distance MPH program for veterinarians working in private practice, industry, and government. Eight veterinarians are participating in the program, which includes two two-week, in-person summer sessions, with the remainder of the coursework taken at a distance via the Internet.

  15. Iowa's oldest oaks. [Quercus alba

    1983-01-01

    Tree-ring analysis revealed 33 living white oaks (Quercus alba) in Iowa that began growing before 1700. Core of wood 4 mm in diameter, each extracted from a radius of a tree trunk were analyzed. The oldest white oak, found in northeastern Warren County, began growing about 1570 and is thus over 410 years old. A chinkapin oak (Quercus muehlenbergii) was also found which was more than 300 years old. Ring widths from the white oaks are well correlated with total precipitation for the twelve months preceding completion of ring formation in July. Reconstructions of annual (August-July) precipitation for 1680-1979, based on the tree rings, indicate that the driest annual period in Iowa was August 1799-July 1800, and that the driest decade began about 1816. Climatic information of this kind, pre-dating written weather records, can be used to augment those records and provide a longer baseline of information for use by climatologists and hydrologic planners.

  3. Additive attacks on speaker recognition

    Farrokh Baroughi, Alireza; Craver, Scott

    2014-02-01

    Speaker recognition is used to identify a speaker's voice from among a group of known speakers. A common method of speaker recognition is a classification based on cepstral coefficients of the speaker's voice, using a Gaussian mixture model (GMM) to model each speaker. In this paper we try to fool a speaker recognition system using additive noise such that an intruder is recognized as a target user. Our attack uses a mixture selected from a target user's GMM model, inverting the cepstral transformation to produce noise samples. In our 5 speaker data base, we achieve an attack success rate of 50% with a noise signal at 10dB SNR, and 95% by increasing noise power to 0dB SNR. The importance of this attack is its simplicity and flexibility: it can be employed in real time with no processing of an attacker's voice, and little computation is needed at the moment of detection, allowing the attack to be performed by a small portable device. For any target user, knowing that user's model or voice sample is sufficient to compute the attack signal, and it is enough that the intruder plays it while he/she is uttering to be classiffed as the victim.

    Major flooding occurred June 8-9, 2008, in the Upper Iowa River Basin in northeast Iowa following severe thunderstorm activity over the region. About 7 inches of rain were recorded for the 48-hour period ending 4 p.m., June 8, at Decorah, Iowa; more than 7 inches of rain were recorded for the 48-hour period ending 7 a.m., June 8, at Dorchester, Iowa, about 17 miles northeast of Decorah. The maximum peak discharge measured in the Upper Iowa River was 34,100 cubic feet per second at streamgage 05387500 Upper Iowa River at Decorah, Iowa. This discharge is the largest discharge recorded in the Upper Iowa River Basin since streamgaging operations began in the basin in 1914. The flood-probability range of the peak discharge is 0.2 to 1 percent. High-water marks were measured at 15 locations along the Upper Iowa River between State Highway 26 near the mouth at the Mississippi River and U.S. Highway 63 at Chester, Iowa, a distance of 124 river miles. The high-water marks were used to develop a flood profile.

  1. The High Fidelity Plasma Speaker

    NASA Astrophysics Data System (ADS)

    McGall, James

    2014-10-01

    A plasma speaker is a device that uses ionized gas as the driving source of sound production, rather than the traditional magnetic coil and membrane setup found on a standard speaker. Similar to how lightning produces sound, or even a small static shock, a plasma speaker uses a modulating electric arc between two electrodes to produce sound. An electric circuit is built that allows the variance of the high voltage electric potential to be controlled by a 3.5 mm standard audio headphone jack, allowing sound energy to be transferred from the plasma to the air by means of pulse width modulation. For my summer project I have built two different models of plasma speakers and am working on a third. The speaker benefits from having a nearly massless driver, and I hypothesize that it should show a response rate faster than that of a traditional speaker and a decreased impulse response while having the drawbacks of inefficiency and a low maximum decibel output. The speakers are currently being optimized with magnetic stabilization of the plasma and will be tested soon for impulse response, frequency generation, efficiency, and audio coloration.

  2. Speaker age and vowel perception.

    PubMed

    Drager, Katie

    2011-03-01

    Recent research provides evidence that individuals shift in their perception of variants depending on social characteristics attributed to the speaker.This paper reports on a speech perception experiment designed to test the degree to which the age attributed to a speaker influences the perception of vowels undergoing a chain shift. As a result of the shift, speakers from different generations produce different variants from one another. Results from the experiment indicate that a speaker's perceived age can influence vowel categorization in the expected direction. However, only older participants are influenced by perceived speaker age.This suggests that social characteristics attributed to a speaker affect speech perception differently depending on the salience of the relationship between the variant and the characteristic.The results also provide evidence of an unexpected interaction between the sex of the participant and the sex of the stimulus.The interaction is interpreted as an effect of the participants' previous exposure with male and female speakers.The results are analyzed under an exemplar model of speech production and perception where social information is indexed to acoustic information and the weight of the connection varies depending on the perceived salience of sociophonetic trends.

Speakers cover a wide range of arctic research topics and can address a variety of audiences including K-12 students, graduate and undergraduate students, and the general public. Host applications are accepted on an on-going basis, depending on funding availability. Applications need to be submitted at least 1 month prior to the expected tour dates. Interested hosts can choose speakers from an online Speakers Bureau or invite a speaker of their choice. Preference is given to individuals and organizations to host speakers that reach a broad audience and the general public. AVS tours are encouraged to span several days, allowing ample time for interactions with faculty, students, local media, and community members. Applications for both domestic and international visits will be considered. Applications for international visits should involve participation of more than one host organization and must include either a US-based speaker or a US-based organization. This is a small but important program that educates the public about Arctic issues. There have been 27 tours since 2007 that have impacted communities across the globe including: Gatineau, Quebec Canada; St. Petersburg, Russia; Piscataway, New Jersey; Cordova, Alaska; Nuuk, Greenland; Elizabethtown, Pennsylvania; Oslo, Norway; Inari, Finland; Borgarnes, Iceland; San Francisco, California and Wolcott, Vermont to name a few. Tours have included lectures to K-12 schools, college and university students, tribal organizations, Boy Scout troops, science center and museum patrons, and the general public. There are approximately 300 attendees enjoying each AVS tour, roughly 4100 people have been reached since 2007. The expectations for each tour are extremely manageable. Hosts must submit a schedule of events and a tour summary to be posted online

    Bedrock in Iowa (Hershey 1969) generally is overlain by deposits of glacial drift and alluvium. The drift, consisting of glacial till and glacial outwash, ranges in thickness from zero to more than 500 feet in western Iowa; the alluvium in stream valleys ranges in thickness from less than 1 to more than 70 feet. The configuration of the bedrock surface is the result of a long period of preglacial erosion and during shorter, but more intense, periods of interglacial erosion.

    Comparison of biochemical test results and protein electrophoretic patterns of 21 strains of Mycoplasma iowae indicated that all were similar. Comparison of agglutination test results indicated marked within-species antigenic variation. None of 21 antigens prepared from different strains were effective in demonstrating turkey antibody against five reference strains. Examination of sera from turkeys exposed by intra-air-sac inoculation to two pathogenic strains also indicated antigenic variation. Neither the M. iowae type-strain, Iowa 695, nor the other reference strains were effective in demonstrating antibody against both strains used to expose the turkeys. These findings suggest that antigenic variation may be a major problem in effective serodiagnosis of M. iowae infections.

  10. The Vienna Heritage of Iowa Orthopaedics

    PubMed Central

    Buckwalter, Joseph A

    2003-01-01

    Strong traditions of basic research, clinical innovation, teaching and integrating science and evaluation of outcomes into clinical practice have characterized University of Iowa orthopaedics for ninety years. These traditions were brought to Iowa City from Vienna when Iowa City was a town of fewer than 10,000 people in a sparsely populated rural state. In the last third of the 19th century, surgeons at the University of Vienna, led by Theodore Billroth (1829-1894), helped transform the practice of surgery. They developed new more effective procedures, analyzed the results of their operations, promoted the emergence and growth of surgical specialties and sought understanding of tissue structure, physiology and pathophysiology. Their efforts made Vienna one of the world's most respected centers for operative treatment, basic and clinical research and surgical education. Two individuals who followed Billroth, Eduard Albert (1841-1900) and Adolf Lorenz (1854-1946) focused their research and clinical practice on orthopaedics. Their successes in the study and treatment of musculoskeletal disorders led one of their students, Arthur Steindler (1878-1959), a 1902 graduate of the Vienna Medical School, to pursue a career in orthopaedics. Following medical school, he worked in Lorenz's orthopaedic clinic until 1907 when he joined John Ridlon (1852-1936) at the Chicago Home for Crippled Children. In 1910, Steindler became Professor of Orthopaedics at the Drake Medical School in Des Moines, Iowa, and, in 1913, John G. Bowman, the President of the University of Iowa, recruited him to establish an orthopaedic clinical and academic program in Iowa City. For the next third of a century he guided the development of the University of Iowa Orthopaedics Department, helped establish the fields of orthopaedic biomechanics and kinesiology and tirelessly stressed the importance of physiology, pathology and assessment of the outcomes of operations. From the legacy of Billroth, Albert and

    Christiansen, Daniel E.; Eash, David A.

    2008-01-01

    The city of Decorah, Iowa, has experienced severe flooding from the Upper Iowa River resulting in property damage to homes and businesses. Streamflow data from two U.S. Geological Survey (USGS) streamflow-gaging stations, the Upper Iowa River at Decorah, Iowa (station number 05387500), located upstream from the College Drive bridge; and the Upper Iowa River near Decorah, Iowa (station number 05388000), at the Clay Hill Road bridge (locally known as the Freeport bridge) were used in the study. The three largest floods on the Upper Iowa River at Decorah occurred in 1941, 1961, and 1993, for which the estimated peak discharges were 27,200 cubic feet per second (ft3/s), 20,200 ft3/s, and 20,500 ft3/s, respectively. Flood-discharge information can be obtained from the World Wide Web at URL (uniform resource locator) http://waterdata.usgs.gov/nwis/. In response to the need to provide the City of Decorah and other flood-plain managers with an assessment of the risks of flooding to properties and facilities along an 8.5-mile (mi) reach of the Upper Iowa River, the USGS, in cooperation with the City of Decorah, initiated a study to map 100- and 500-year flood-prone areas.

  15. Iowa satellite project ISAT-1

    NASA Technical Reports Server (NTRS)

    1993-01-01

    Satellite systems to date have been mainly scientific in nature. Only a few systems have been of direct use to the public such as for telephone or television transmission. Space enterprises have remained a mystery to the general public and beyond the reach of the small business community. The result is a less than supportive public when it comes to space activities. The purpose of the ISAT-1 program is to develop a small and relatively inexpensive satellite that will serve the State of Iowa, primarily for educational purposes. It will provide products, services, and activities that will be educational, practical, and useful for a large number for people. The emphasis is on public awareness, 'space literacy', and routine practical applications rather than high technology. The initial conceptual design phase was complete when the current team took over the project. Some areas of the conceptual design were taken a little farther, but for the most part this team started at the detailed design stage.

  16. Biosolids composting in Davenport, Iowa

    SciTech Connect

    Boyette, R.A.; Williams, T.; Plett, S.

    1996-09-01

    The City of Davenport, Iowa constructed an aerated static pile composting facility to process 28 dry tons per day of dewatered biosolids and 25,000 cubic yards per year of yard wastes. This is the first large totally enclosed aerated static pile biosolids composting facility to be built in several years in the US. Design of the facility was completed in March 1994, construction began in July 1994, with substantial completion of the facility in August 1995. This paper outlines the major operating systems and describes the major components of the facility. The facility processes all of the City`s anaerobically digested biosolids which is currently dewatered by belt filter presses to 20% solids. Yard wastes are used as the primary bulking agent supplemented by wood chips and shredded rubber tires to minimize O and M costs. A mechanized continuous feed mixing system consisting of hoppers, conveyors, and pugmill mixers is used to combine bulk agents with the dewatered biosolids to the desired ratio for composting. Composting and drying of these materials occurs in a totally enclosed pre-fabricated metal building for maximum environmental control and odor control. Multiple aeration stations provide both positive and negative aeration through pre-cast aeration trenches beneath compost piles.

  17. Quantifying stressors among Iowa farmers.

    PubMed

    Freeman, S A; Schwab, C V; Jiang, Q

    2008-10-01

    In order to identify events/activities that are particularly stressful for farmers/ranchers, afarm stress survey based on the proportionate scaling method was mailed to a stratified random sample of 3000 Iowa farmers by the USDA National Agricultural Statistics Service. The participants were asked to compare 62 life events and farm activities to a marriage (assigned a baseline rating of 50), decide if it was less stressful or more stressful, and then assign a stress rating between 1 and 100. As expected, the most stressful events were the death of a spouse or child. Other high-stress events were disabling injuries, foreclosure on a mortgage, divorce, machinery breakdown during harvest, and loss of crop to weather. Mean stress ratings varied by age, marital status, and type of farming enterprise. Farmers between the ages of 40-59 and 60-79 had the most items with high stress levels. Females had more high-stress items than males. Divorced farmers had fewer high-stress items than other respondents. Farmer's whose primary focus was raising horses had more high-stress items than other farm types. Significant outcomes of this study go beyond the specific mean stress ratings of the events and activities. The results indicate that farm stressors can be quantified using the proportionate scaling method and that the impact of the stressor is based not just on the event but is also dependent on the characteristics of the farmer (e.g., age, gender, marital status, etc.).

    2013-12-01

    The Arctic Visiting Speakers Program (AVS) is a program of the Arctic Research Consortium of the U.S. (ARCUS) and funded by the National Science Foundation. AVS provides small grants to researchers and other Arctic experts to travel and share their knowledge in communities where they might not otherwise connect. The program aims to: initiate and encourage arctic science education in communities with little exposure to arctic research; increase collaboration among the arctic research community; nurture communication between arctic researchers and community residents; and foster arctic science education at the local level. Individuals, community organizations, and academic organizations can apply to host a speaker. Speakers cover a wide range of arctic topics and can address a variety of audiences including K-12 students, graduate and undergraduate students, and the general public. Preference is given to tours that reach broad and varied audiences, especially those targeted to underserved populations. Between October 2000 and July 2013, AVS supported 114 tours spanning 9 different countries, including tours in 23 U.S. states. Tours over the past three and a half years have connected Arctic experts with over 6,600 audience members. Post-tour evaluations show that AVS consistently rates high for broadening interest and understanding of arctic issues. AVS provides a case study for how face-to-face interactions between arctic scientists and general audiences can produce high-impact results.

  13. Holocene paleoenviroments of northwest Iowa

    SciTech Connect

    Baker, R.G.; Bettis, E.A. III; Schwert, D.P.

    1996-05-01

    This paper presents the biotic, sedimentary, geomorphic, and climatic history of the upper part of the Roberts Creek Basin, northeastern Iowa for the late-glacial and Holocene, and compares these records with a C-O isotopic sequence from Coldwater Cave, 60 km northwest of Roberts Creek. the biotic record (pollen, vascular plant and bryophyte macrofossils, and insects) is preserved in floodplain alluvium that underlies three constructional surfaces separated by low scarps. Each surface is underlain by a lithologically and temporally distinct alluvial fill. The highest surface is underlain by the Gunder Member of the Deforest Formation, dating from 11,000 to 4000 yr BP; beneath the intermediate level is the Roberts Creek Member, dating from 4000 to 400 yr BP; and the lowest level is underlain by the Camp Creek Member, deposited during the last 380 yr. Pollen and plant macrofossils in the alluvial fill show that a typical late-glacial spruce forest was replaced by Quercus and Ulmus in the early Holocene. This early-to-middle Holocene forest became dominated by medic elements such as Acer saccharum, Tila americana, Ostyra virginiana, and Carpinus caroliniana as late as 5500 yr BP; in contrast, the closest sites to the west and north were at their warmest and driest were covered by prairie vegetation between 6500 and 5500 yr BP. After 5500 yr BP, the forest in the roberts Creek area was replaced by prairie, as indicated by a rich assemblage of plant macrofossils, although only Ambrosia and Poaceae became abundant in the pollen record. The return of Quercus {approx} 3000 BP (while nonarboreal pollen percentages remained relatively high) indicates the oak savanna prevailed with little change until settlement time. 83 refs., 17 figs., 5 tabs.

    This paper presents the biotic. sedimentary, geomorphic, and climatic history of the upper part of the Roberts Creek Basin, northeastern Iowa for the late-glacial and Holocene, and compares these records with a C-O isotopic sequence from Coldwater Cave. 60 km northwest of Roberts Creek. The biotic record (pollen, vascular plant and bryophyle macrofossils. and insects) is preserved in floodplain alluvium that underlies three constructional surfaces separated by low scarps. Each surface is underlain by a lithologically and temporally distinct alluvial fill. The highest surface is underlain by the Gunder Member of the Deforest Formation, dating from 11 000 to 4000 yr BP; beneath the intermediate level is the Roberts Creek Member, dating from 4000 to 400 yr BP; and the lowest level is underlain by the Camp Creek Member, deposited during the last 380 yr. Pollen and plant macrofossils in the alluvial fill show that a typical late-glacial spruce forest was replaced by Quercus and Ulmus in the early Holocene. This early-to-middle Holocene forest became dominated by mesic elements such as Acer saccharum, Tilia americana, Ostrya virginiana, and Carpinus caroliniana as late as 5500 yr BP; in contrast, the closest sites to the west and north were at their warmest and driest and were covered by prairie vegetation between 6500 and 5500 yr BP. After 5500 yr BP, the forest in the Roberts Creek area was replaced by prairie, as indicated by a rich assemblage of plant macrofossils, although only Ambrosia and Poaceae became abundant in the pollen record. The return of Quercus ??? 3000 BP (while nonarboreal pollen percentages remained relatively high) indicates that oak savanna prevailed with little change until settlement time. The bryophyte assemblages strongly support the vascular plant record. Rich fen species characteristic of boreal habitats occur only in the late-glacial. They are replaced by a number of deciduous-forest elements when early-to-middle Holocene forests were

  3. Speaker independent acoustic-to-articulatory inversion

    NASA Astrophysics Data System (ADS)

    Ji, An

    Acoustic-to-articulatory inversion, the determination of articulatory parameters from acoustic signals, is a difficult but important problem for many speech processing applications, such as automatic speech recognition (ASR) and computer aided pronunciation training (CAPT). In recent years, several approaches have been successfully implemented for speaker dependent models with parallel acoustic and kinematic training data. However, in many practical applications inversion is needed for new speakers for whom no articulatory data is available. In order to address this problem, this dissertation introduces a novel speaker adaptation approach called Parallel Reference Speaker Weighting (PRSW), based on parallel acoustic and articulatory Hidden Markov Models (HMM). This approach uses a robust normalized articulatory space and palate referenced articulatory features combined with speaker-weighted adaptation to form an inversion mapping for new speakers that can accurately estimate articulatory trajectories. The proposed PRSW method is evaluated on the newly collected Marquette electromagnetic articulography -- Mandarin Accented English (EMA-MAE) corpus using 20 native English speakers. Cross-speaker inversion results show that given a good selection of reference speakers with consistent acoustic and articulatory patterns, the PRSW approach gives good speaker independent inversion performance even without kinematic training data.

    The leaching of phosphorus (P), nitrogen (N), and radionuclides [sup 232]Th, [sup 226]Ra, [sup 228]Ra, and [sup 40]K from Joel sands amended with red mud/gypsum (RMG) at 9 rates (0, 2, 4, 8, 16, 32, 64, 128, and 256 t/ha) was measured using columns. Intense leaching conditions (34 mm/day for 12 days) and a high rate of applied P (320 kg/ha as superphosphate) and N (680 kg/ha as ammonium nitrate) were used to simulate extremes of irrigated vegetable production on the Swan Coastal Plain. Addition of the highest rate of RMG (256 t/ha) reduced leaching of fertiliser P and ammonium-nitrogen (NH4-N) by 85% and 50%, respectively, compared with 0 t/ha after 12 days. At 64 t RMG/ha P leaching was reduced 50% compared with 0 t/ha. Nitrate-nitrogen (NO3-N) leaching was not affected by addition of RMG. Reduced leaching of NH4-N was attributed to an increase in cation exchange capacity of the soil with the addition of RMG. Bicarbonate-extractable P in the soil increased with rate of RMG to >50 [mu]g P/g soil at 256 t/ha. This indicates that soil testing of residual P could be used to reduce P inputs to vegetable crops after soils were amended with RMG. This would further reduce the impact of vegetable production on the water systems of the Swan Coastal Plain and extend the period of effectiveness of RMG amended soils. The increase in [sup 232]Th specific activity in Joel sand amended with RMG was well below statutory limits even at the highest rate. Neither [sup 40]K nor [sup 226]Ra were detectable in RMG amended sands up to 256 t RMG/ha. There was no evidence of leaching of [sup 226]Ra or [sup 228]Ra at any rate of RMG. These results suggest that the use of RMG amendment on commercial horticultural properties on the Swan Coastal Plain could be feasible. 30 refs., 7 figs., 2 tabs.

    Human listeners are capable of identifying a speaker, over the telephone or an entryway out of sight, by listening to the voice of the speaker. Achieving this intrinsic human specific capability is a major challenge for Voice Biometrics. Like human listeners, voice biometrics uses the features of a person's voice to ascertain the speaker's identity. The best-known commercialized forms of voice Biometrics is Speaker Recognition System (SRS). Speaker recognition is the computing task of validating a user's claimed identity using characteristics extracted from their voices. This literature survey paper gives brief introduction on SRS, and then discusses general architecture of SRS, biometric standards relevant to voice/speech, typical applications of SRS, and current research in Speaker Recognition Systems. We have also surveyed various approaches for SRS.

  7. Magnetic Fluids Deliver Better Speaker Sound Quality

    NASA Technical Reports Server (NTRS)

    2015-01-01

    In the 1960s, Glenn Research Center developed a magnetized fluid to draw rocket fuel into spacecraft engines while in space. Sony has incorporated the technology into its line of slim speakers by using the fluid as a liquid stand-in for the speaker's dampers, which prevent the speaker from blowing out while adding stability. The fluid helps to deliver more volume and hi-fidelity sound while reducing distortion.

  8. Automatic source speaker selection for voice conversion.

    Turk, Oytun; Arslan, Levent M

    2009-01-01

    This paper focuses on the importance of source speaker selection for a weighted codebook mapping based voice conversion algorithm. First, the dependency on source speakers is evaluated in a subjective listening test using 180 different source-target pairs from a database of 20 speakers. Subjective scores for similarity to target speaker's voice and quality are obtained. Statistical analysis of scores confirms the dependence of performance on source speakers for both male-to-male and female-to-female transformations. A source speaker selection algorithm is devised given a target speaker and a set of source speaker candidates. For this purpose, an artificial neural network (ANN) is trained that learns the regression between a set of acoustical distance measures and the subjective scores. The estimated scores are used in source speaker ranking. The average cross-correlation coefficient between rankings obtained from median subjective scores and rankings estimated by the algorithm is 0.84 for similarity and 0.78 for quality in male-to-male transformations. The results for female-to-female transformations were less reliable with a cross-correlation value of 0.58 for both similarity and quality.

  9. Analysis of Polish Vowels of Tracheoesophageal Speakers.

    The aim of this study was to determine the acoustical differences between normal and tracheoesophageal Polish speakers during Polish vowel production. Formant frequencies, namely, the first (F1) and second (F2) formant frequencies for 6 Polish vowels produced by 11 normal and 11 tracheoesophageal speakers, were analyzed using statistical analysis of variance and discriminant analysis. Spectral analysis showed that the F1 and F2 values of Polish vowels produced by tracheoesophageal speakers were significantly higher than those produced by normal speakers, with the exception of the F2 value of /i/ produced by tracheoesophageal speakers. Analysis of variance showed significant differences between speeches based on the F1 and F2 formant frequencies. Discriminant analysis based on the formant frequencies for F1 and F2 exhibited 73.33% of the mean classification score for tracheoesophageal speakers and 96.36% for normal speakers. Tracheoesophageal speakers exhibit higher F1 and F2 formant frequencies, with the exception of the F2 value for the vowel /i/ than normal speakers. Discriminant analysis showed that the classification process for TE speech exhibits lower accuracy due to the poorer classification of the vowels /i/, /u/, and /y/.

    The bedrock in Iowa (Hershey, 1969) is generally overlain by deposits of glacial drift and alluvium, which range in thickness from less than 1 ft to more than 400 ft, and from less than 1 ft to about 60 ft respectively. The configuration of the bedrock surface is the result of a complex system of ancient drainage courses which were developed during a long period of preglacial erosion and during shorter, but mroe intense, periods of interglacial erosion.

  19. Eleven-year trend in acetanilide pesticide degradates in the Iowa River, Iowa.

    Kalkhoff, Stephen J; Vecchia, Aldo V; Capel, Paul D; Meyer, Michael T

    2012-01-01

    Trends in concentration and loads of acetochlor, alachlor, and metolachlor and their ethanasulfonic (ESA) and oxanilic (OXA) acid degradates were studied from 1996 through 2006 in the main stem of the Iowa River, Iowa and in the South Fork Iowa River, a small tributary near the headwaters of the Iowa River. Concentration trends were determined using the parametric regression model SEAWAVE-Q, which accounts for seasonal and flow-related variability. Daily estimated concentrations generated from the model were used with daily streamflow to calculate daily and yearly loads. Acetochlor, alachlor, metolachlor, and their ESA and OXA degradates were generally present in >50% of the samples collected from both sites throughout the study. Their concentrations generally decreased from 1996 through 2006, although the rate of decrease was slower after 2001. Concentrations of the ESA and OXA degradates decreased from 3 to about 23% yr. The concentration trend was related to the decreasing use of these compounds during the study period. Decreasing concentrations and constant runoff resulted in an average reduction of 10 to >3000 kg per year of alachlor and metolachlor ESA and OXA degradates being transported out of the Iowa River watershed. Transport of acetochlor and metolachlor parent compounds and their degradates from the Iowa River watershed ranged from <1% to about 6% of the annual application. These trends were related to the decreasing use of these compounds during the study period, but the year-to-year variability cannot explain changes in loads based on herbicide use alone. The trends were also affected by the timing and amount of precipitation. As expected, increased amounts of water moving through the watershed moved a greater percentage of the applied herbicides, especially the relatively soluble degradates, from the soils into the rivers through surface runoff, shallow groundwater inflow, and subsurface drainage.

  7. Voice aftereffects of adaptation to speaker identity.

    2010-09-01

    While adaptation to complex auditory stimuli has traditionally been reported for linguistic properties of speech, the present study demonstrates non-linguistic high-level aftereffects in the perception of voice identity, following adaptation to voices or faces of personally familiar speakers. In Exp. 1, prolonged exposure to speaker A's voice biased the perception of identity-ambiguous voice morphs between speakers A and B towards speaker B (and vice versa). Significantly biased voice identity perception was also observed in Exp. 2 when adaptors were videos of speakers' silently articulating faces, although effects were reduced in magnitude relative to those seen in Exp. 1. By contrast, adaptation to an unrelated speaker C elicited an intermediate proportion of speaker A identifications in both experiments. While crossmodal aftereffects on auditory identification (Exp. 2) dissipated rapidly, unimodal aftereffects (Exp. 1) were still measurable a few minutes after adaptation. These novel findings suggest contrastive coding of voice identity in long-term memory, with at least two perceptual mechanisms of voice identity adaptation: one related to auditory coding of voice characteristics, and another related to multimodal coding of familiar speaker identity.

It is organized into a model based on (i) application of a rigorous research program validating the system, (ii) an upgrading of the organization of the SI area, and (iii) exploitation of new technology. The second part of the presentation will describe an illustrative speech/voice approach to SI development. This effort is also based on an extensive corpus of research. It is suggested that application of the cited standards, plus the illustrative model, will permit reasonable progress to be made. Finally, a number of procedural recommendations are made; they should enhance the efficacy of the proposed approach. © 2016 American Academy of Forensic Sciences.

  9. Learning words from speakers with false beliefs.

    2017-07-01

    During communication, hearers try to infer the speaker's intentions to be able to understand what the speaker means. Nevertheless, whether (and how early) preschoolers track their interlocutors' mental states is still a matter of debate. Furthermore, there is disagreement about how children's ability to consult a speaker's belief in communicative contexts relates to their ability to track someone's belief in non-communicative contexts. Here, we study young children's ability to successfully acquire a word from a speaker with a false belief; we also assess the same children's success on a traditional false belief attribution task. We show that the ability to consult the epistemic state of a speaker during word learning develops between the ages of three and five. We also show that false belief understanding in word-learning contexts proceeds similarly to standard belief-attribution contexts when the tasks are equated. Our data offer evidence for the development of mind-reading abilities during language acquisition.

  10. Floods of May 30 to June 15, 2008, in the Iowa and Cedar River basins, eastern Iowa

    2010-01-01

    As a result of prolonged and intense periods of rainfall in late May and early June, 2008, along with heavier than normal snowpack the previous winter, record flooding occurred in Iowa in the Iowa River and Cedar River Basins. The storms were part of an exceptionally wet period from May 29 through June 12, when an Iowa statewide average of 9.03 inches of rain fell; the normal statewide average for the same period is 2.45 inches. From May 29 to June 13, the 16-day rainfall totals recorded at rain gages in Iowa Falls and Clutier were 14.00 and 13.83 inches, respectively. Within the Iowa River Basin, peak discharges of 51,000 cubic feet per second (flood-probability estimate of 0.2 to 1 percent) at the 05453100 Iowa River at Marengo, Iowa streamflow-gaging station (streamgage) on June 12, and of 39,900 cubic feet per second (flood-probability estimate of 0.2 to 1 percent) at the 05453520 Iowa River below Coralville Dam near Coralville, Iowa streamgage on June 15 are the largest floods on record for those sites. A peak discharge of 41,100 cubic feet per second (flood-probability estimate of 0.2 to 1 percent) on June 15 at the 05454500 Iowa River at Iowa City, Iowa streamgage is the fourth highest on record, but is the largest flood since regulation by the Coralville Dam began in 1958. Within the Cedar River Basin, the May 30 to June 15, 2008, flood is the largest on record at all six streamgages in Iowa located on the mainstem of the Cedar River and at five streamgages located on the major tributaries. Flood-probability estimates for 10 of these 11 streamgages are less than 1 percent. Peak discharges of 112,000 cubic feet per second (flood-probability estimate of 0.2 to 1 percent) at the 05464000 Cedar River at Waterloo, Iowa streamgage on June 11 and of 140,000 cubic feet per second (flood-probability estimate of less than 0.2 percent) at the 05464500 Cedar River at Cedar Rapids, Iowa streamgage on June 13 are the largest floods on record for those sites.

  20. Iowa Wavering on Medicaid: From Expansion to Modernization.

    PubMed

    Wright, Brad; Potter, Andrew J; Nattinger, Matthew C

    2016-04-01

    Iowa is one of six states to expand Medicaid through section 1115 waivers. Iowa's alternative approach to Medicaid expansion, known as the Iowa Health and Wellness Plan, was the result of a bipartisan compromise, motivated by the pending expiration of a preexisting section 1115 waiver that served sixty-five thousand Iowans. The Iowa Health and Wellness Plan emphasizes personal responsibility and private involvement. Key features include beneficiary premiums, incentives for healthy behaviors, and premium assistance for some beneficiaries to purchase insurance in the health insurance marketplace. However, Iowa has struggled to implement its expansion as initially envisioned, due largely to the lack of private insurers willing and able to insure new Medicaid enrollees in the marketplace. In 2016 Iowa will dramatically increase the role of managed care in Medicaid, with the vast majority of beneficiaries receiving almost all Medicaid services through a capitated managed care organization. This article highlights the local factors driving expansion, the interplay of the state and federal political landscape, the challenges of providing consumer choice within Iowa's marketplace, and the future of Iowa's Medicaid program under managed care.

  18. Planned Parenthood of Greater Iowa, Inc. v. Miller.

    PubMed

    1999-09-24

    The U.S. Court of Appeals for the Eighth Circuit found an Iowa statute banning partial-birth abortions to be unconstitutional. Nonprofit corporations that operate abortion clinics, physicians who perform abortions, and medical professors who taught abortion methods, had challenged the constitutionality of Iowa's statute in a lower court. The lower court had held that Iowa's statute was unconstitutional under the Fourteenth Amendment to the U.S. Constitution, and the U.S. Court of Appeals agreed. Although the Iowa statute was intended to ban the dilation and extraction procedure, it implicitly banned commonly used abortion procedures in the second trimester, such as suction-curettage and dilation and evacuation. The Court of Appeals ruled that the Iowa statute created an undue burden for women seeking pre-viability abortions.

  19. Evaluation of Iowa's anti-bullying law.

    Ramirez, Marizen; Ten Eyck, Patrick; Peek-Asa, Corinne; Onwuachi-Willig, Angela; Cavanaugh, Joseph E

    Bullying is the most common form of youth aggression. Although 49 of all 50 states in the U.S. have an anti-bullying law in place to prevent bullying, little is known about the effectiveness of these laws. Our objective was to measure the effectiveness of Iowa's anti-bullying law in preventing bullying and improving teacher response to bullying. Sixth, 8th, and 11th grade children who completed the 2005, 2008 and 2010 Iowa Youth Survey were included in this study (n = 253,000). Students were coded according to exposure to the law: pre-law for 2005 survey data, one year post-law for 2008 data, and three years post-law for 2010 data. The outcome variables were: 1) being bullied (relational, verbal, physical, and cyber) in the last month and 2) extent to which teachers/adults on campus intervened with bullying. Generalized linear mixed models were constructed with random effects. The odds of being bullied increased from pre-law to one year post-law periods, and then decreased from one year to three years post-law but not below 2005 pre-law levels. This pattern was consistent across all bullying types except cyberbullying. The odds of teacher intervention decreased 11 % (OR = 0.89, 95 % CL = 0.88, 0.90) from 2005 (pre-law) to 2010 (post-law). Bullying increased immediately after Iowa's anti-bullying law was passed, possibly due to improved reporting. Reductions in bullying occurred as the law matured. Teacher response did not improve after the passage of the law.

  1. Quantity language speakers show enhanced subcortical processing.

    Dawson, Caitlin; Aalto, Daniel; Šimko, Juraj; Putkinen, Vesa; Tervaniemi, Mari; Vainio, Martti

    2016-07-01

    The complex auditory brainstem response (cABR) can reflect language-based plasticity in subcortical stages of auditory processing. It is sensitive to differences between language groups as well as stimulus properties, e.g. intensity or frequency. It is also sensitive to the synchronicity of the neural population stimulated by sound, which results in increased amplitude of wave V. Finnish is a full-fledged quantity language, in which word meaning is dependent upon duration of the vowels and consonants. Previous studies have shown that Finnish speakers have enhanced behavioural sound duration discrimination ability and larger cortical mismatch negativity (MMN) to duration change compared to German and French speakers. The next step is to find out whether these enhanced duration discrimination abilities of quantity language speakers originate at the brainstem level. Since German has a complementary quantity contrast which restricts the possible patterns of short and long vowels and consonants, the current experiment compared cABR between nonmusician Finnish and German native speakers using seven short complex stimuli. Finnish speakers had a larger cABR peak amplitude than German speakers, while the peak onset latency was only affected by stimulus intensity and spectral band. The results suggest that early cABR responses are better synchronised for Finns, which could underpin the enhanced duration sensitivity of quantity language speakers. Copyright © 2016 The Authors.

  2. Nonuniform speaker normalization using affine transformation.

    PubMed

    Bharath Kumar, S V; Umesh, S

    2008-09-01

    In this paper, a well-motivated nonuniform speaker normalization model that affinely relates the formant frequencies of speakers enunciating the same sound is proposed. Using the proposed affine model, the corresponding universal-warping function that is required for normalization is shown to have the same parametric form as the mel scale formula. The parameters of this universal-warping function are estimated from the vowel formant data and are shown to be close to the commonly used formula for the mel scale. This shows an interesting connection between nonuniform speaker normalization and the psychoacoustics based mel scale. In addition, the affine model fits the vowel formant data better than commonly used ad hoc normalization models. This work is motivated by a desire to improve the performance of speaker-independent speech recognition systems, where speaker normalization is conventionally done by assuming a linear-scaling relationship between spectra of speakers. The proposed affine relation is extended to describe the relationship between spectra of speakers enunciating the same sound. On a telephone-based connected digit recognition task, the proposed model provides improved recognition performance over the linear-scaling model.

    The hydrologic investigations atlas shows the areas in and around Iowa City, Iowa, that were flooded by the Iowa River in 1993. This map also depicts the Federal Emergency Management Agency (FEMA) 100-year flood boundaries. The drainage basin of the Iowa River at Iowa City received well over 100 percent of normal rainfall in June, July, and August, 1993. At the Cedar Rapids airport, located about 20 miles north-northwest of Iowa City, July rainfall was 414 percent of normal. The discharges at U.S. Geological Survey streamflow-gaging stations on the Iowa River upstream of Coralville Reservoir, just downstream from Coralville Reservoir, and at Iowa City are shown. A profile of the maximum water-surface elevations of the 1993 flood in Iowa City and vicinity is higher than the FEMA 100-year flood profile. The water-surface elevation of Coralville Reservoir is shown from June 29-September 18, 1993.

    Urban storm water runoff is being investigated as a nonpoint source of pollution across the country as urban areas with populations over 100,000 conduct studies designed to meet U.S. Environmental Protection Agency guidelines for National Pollutant Discharge Elimination System permits for their stormwater discharges. From 1991 through 1994, the City of Davenport, Iowa (fig. 1), and the U.S. Geological Survey cooperatively conducted a study designed to meet technical conditions of the permit application and to develop the criteria for ongoing monitoring during the term of the permit.

    2017-03-01

    Although the word and sentence recognition skills of cochlear implant (CI) users have been studied extensively, little is known about their ability to distinguish between individuals on the basis of voice, an important skill for social communication. Speech material from the Oldenburg Logatome Corpus (OLLO) was used to build a set of 120 logatome pairs spoken by 15 male and 15 female speakers, with no overlap of the fundamental frequencies of the two groups of speakers. Each pair contained two different logatomes. For half of the pairs, the two logatomes were spoken by the same speaker, for the other half they were spoken by different speakers. Using a same-different paradigm, 13 adult normal-hearing listeners and 13 adult post-lingually deafened CI users were asked whether the pair of different logatomes were spoken by the same or by different speakers. Mean speaker discrimination score for the CI users was 74.6 % correct and for the normal-hearing listeners 89.6 % correct. A significant influence of voice gender on speaker discrimination score was found in CI users and in normal hearing listeners. The results of the CI users were significantly above the level of chance and no ceiling effect was observed for the normal-hearing listeners, i. e., the presented set of logatome pairs from the OLLO seems to be very well suited to speaker discrimination experiments in CI users and quantitative comparison to normal-hearing listeners. CI users are able to discriminate between speakers but their performance is slightly worse than that of normal-hearing listeners.

  16. Climate Change and Maize Yield in Iowa.

    Xu, Hong; Twine, Tracy E; Girvetz, Evan

    2016-01-01

    Climate is changing across the world, including the major maize-growing state of Iowa in the USA. To maintain crop yields, farmers will need a suite of adaptation strategies, and choice of strategy will depend on how the local to regional climate is expected to change. Here we predict how maize yield might change through the 21st century as compared with late 20th century yields across Iowa, USA, a region representing ideal climate and soils for maize production that contributes substantially to the global maize economy. To account for climate model uncertainty, we drive a dynamic ecosystem model with output from six climate models and two future climate forcing scenarios. Despite a wide range in the predicted amount of warming and change to summer precipitation, all simulations predict a decrease in maize yields from late 20th century to middle and late 21st century ranging from 15% to 50%. Linear regression of all models predicts a 6% state-averaged yield decrease for every 1°C increase in warm season average air temperature. When the influence of moisture stress on crop growth is removed from the model, yield decreases either remain the same or are reduced, depending on predicted changes in warm season precipitation. Our results suggest that even if maize were to receive all the water it needed, under the strongest climate forcing scenario yields will decline by 10-20% by the end of the 21st century.

  19. What the speaker means: the recognition of speakers plans in discourse

    SciTech Connect

    Sidner, C.L.

    1983-01-01

    Human conversational participants depend upon the ability of their partners to recognize their intentions, so that those partners may respond appropriately. In such interactions, the speaker encodes his intentions about the hearer's response in a variety of sentence types. Instead of telling the hearer what to do, the speaker may just state his goals, and expect a response that meets these goals at least part way. This paper presents a new model for recognizing the speaker's intended meaning in determining a response. It shows that this recognition makes use of the speaker's plan, his beliefs about the domain and about the hearer's relevant capacities. 12 references.

  20. Between-speaker and within-speaker variation in speech tempo of American English.

    Jacewicz, Ewa; Fox, Robert Allen; Wei, Lai

    2010-08-01

    This study characterizes the speech tempo (articulation rate, excluding pauses) of two distinct varieties of American English taking into account both between-speaker and within-speaker variation. Each of 192 speakers from Wisconsin (the northern variety) and from North Carolina (the southern variety), men and women, ranging in age from children to old adults, read a set of sentences and produced a spontaneous unconstrained talk. Articulation rate in spontaneous speech was modeled using fixed-mixed effects analyses. The models explored the effects of the between-speaker factors dialect, age and gender and included each phrase and its length as a source of both between- and within-speaker variation. The major findings are: (1) Wisconsin speakers speak significantly faster and produce shorter phrases than North Carolina speakers; (2) speech tempo changes across the lifespan, being fastest for individuals in their 40s; (3) men speak faster than women and this effect is not related to the length of phrases they produce. Articulation rate in reading was slower than in speaking and the effects of gender and age also differed in reading and spontaneous speech. The effects of dialect in reading remained the same, showing again that Wisconsin speakers had faster articulation rates than did North Carolina speakers.

  1. Floods of May and June 2008 in Iowa

    USGS Publications Warehouse

    Buchmiller, Robert C.; Eash, David A.

    2010-01-01

    An unusually wet winter and spring of 2007 to 2008 resulted in extremely wet antecedent conditions throughout most of Iowa. Rainfall of 5 to 15 inches was observed in eastern Iowa during May 2008, and an additional 5 to 15 inches of rain was observed throughout most of Iowa in June. Because of the severity of the May and June 2008 flooding, the U.S. Geological Survey, in cooperation with other Federal, State, and local agencies, has summarized the meteorological and hydrological conditions leading to the flooding, compiled flood-peak stages and discharges, and estimated revised flood probabilities for 62 selected streamgages. Record peak discharges or flood probabilities of 1 percent or smaller (100-year flooding or greater) occurred at more than 60 streamgage locations, particularly in eastern Iowa. Cedar Rapids, Decorah, Des Moines, Iowa City, Mason City, and Waterloo were among the larger urban areas affected by this flooding. High water and flooding in small, headwater streams in north-central and eastern Iowa, particularly in June, combined and accumulated in large, mainstem rivers and resulted in flooding of historic proportions in the Cedar and Iowa Rivers. Previous flood-peak discharges at many locations were exceeded by substantial amounts, in some cases nearly doubling the previous record peak discharge at locations where more than 100 years of streamflow record are available.

  2. Relation of baseflow to row crop intensity in Iowa

    USGS Publications Warehouse

    Schilling, K.E.

    2005-01-01

    Increasing baseflow and baseflow percentage over the second half of the 20th century in Iowa has contributed to increasing nitrate-nitrogen concentrations measured in Iowa rivers because nitrate is primarily delivered to streams as baseflow and tile drainage. The relation of baseflow and baseflow percentage to row crop land use was evaluated for 11 Iowa rivers and their watersheds for their period of streamflow record (58-73 years period). Results indicated increasing baseflow in Iowa's rivers is significantly related to increasing row crop intensity. A 13-52% increase in row crop percentage in many Iowa watersheds has contributed to an increase of 33-135 mm increase in baseflow and 7-31% increase in baseflow percentage. Limited historical water quality data from two larger Iowa rivers (Cedar and Raccoon rivers) suggest that increasing row crop land use over the 20th century has produced more baseflow and contributed to increasing nitrate concentrations in Iowa's rivers. ?? 2004 Elsevier B.V.

  3. Pitch Correlogram Clustering for Fast Speaker Identification

    NASA Astrophysics Data System (ADS)

    Jhanwar, Nitin; Raina, Ajay K.

    2004-12-01

    Gaussian mixture models (GMMs) are commonly used in text-independent speaker identification systems. However, for large speaker databases, their high computational run-time limits their use in online or real-time speaker identification situations. Two-stage identification systems, in which the database is partitioned into clusters based on some proximity criteria and only a single-cluster GMM is run in every test, have been suggested in literature to speed up the identification process. However, most clustering algorithms used have shown limited success, apparently because the clustering and GMM feature spaces used are derived from similar speech characteristics. This paper presents a new clustering approach based on the concept of a pitch correlogram that captures frame-to-frame pitch variations of a speaker rather than short-time spectral characteristics like cepstral coefficient, spectral slopes, and so forth. The effectiveness of this two-stage identification process is demonstrated on the IVIE corpus of 110 speakers. The overall system achieves a run-time advantage of 500% as well as a 10% reduction of error in overall speaker identification.

  4. Generalized dimensions applied to speaker identification

    Hou, Limin; Wang, Shuozhong

    2004-08-01

    This paper describes an application of fractal dimensions to speech processing and speaker identification. There are several dimensions that can be used to characterize speech signals such as box dimension, correlation dimension, etc. We are mainly concerned with the generalized dimensions of speech signals as they provide more information than individual dimensions. Generalized dimensions of arbitrary orders are used in speaker identification in this work. Based on the experimental data, the artificial phase space is generated and smooth behavior of correlation integral is obtained in a straightforward and accurate analysis. Using the dimension D(2) derived from the correlation integral, the generalized dimension D(q) of an arbitrary order q is calculated. Moreover, experiments applying the generalized dimension in speaker identification have been carried out. A speaker recognition dedicated Chinese language speech corpus with PKU-SRSC, recorded by Peking University, was used in the experiments. The results are compared to a baseline speaker identification that uses MFCC features. Experimental results have indicated the usefulness of fractal dimensions in characterizing speaker's identity.

  7. Agro-energy: Redefining energy and agriculture in Iowa

    SciTech Connect

    Cooper, J.T.

    1995-11-01

    Recent advantages in technology are leading to increased interest in agriculture as a source of energy. The replacement of fossil fuels with biomass is quite feasible in the near future. Investigation of renewable energy in Iowa has centered around the use of agricultural crops to generate electrical energy. Switchgrass, a native grass of Iowa, is one of the most promising biomass producers. Chariton Valley RC&D Inc., a USDA sponsored rural development organization based in southern Iowa and IES Utilities, a major Iowa energy company, are leading a statewide coalition of public and private interests to merge Iowa`s agricultural potential with long-term energy requirements to develop a locally sustainable source of biomass fuel. Many of the sois of southern Iowa are best suited to the production of forages and trees. Farm program changes, and the eventual end of the Conservation Reserve Program (CRP) make adding value and establishing long term markets for perennial forage crops vital for the area`s continued prosperity. Ten percent of the total land in the four county Chariton Valley area is in CRP -- 140,000 acres. Thousands more acres of marginal lands not in CRP, have limited production potential and would be available for biomass production. The associated benefits to water quality, sustainable soil capabilities and the local economy are phenomenal. IES Utilities is working with Iowa State University, R.W. Beck and other private industry interests to identify and develop the technology to convert agricultural crops to energy. The long term plan calls for 35 MW of electrical power production using a dedicated supply of biomass to be established in southern Iowa. This facility would use approximately 30,000 to 40,000 acres. Co-firing biomass with coal appears to provide a short cut to commercial use of biomass and will enhance interest in emerging advanced technologies.

    At the request of the U.S. Department of Energy (DOE), a team from Oak Ridge National Laboratory conducted an indoor radiological survey of property at the Iowa Army Ammunition Plant (IAAAP), Middletown, Iowa in June 2000. The purpose of the survey was to determine if radioactive residuals resulting from previous Atomic Energy Commission (AEC) activities were present inside selected Line 1 buildings at the IAAAP and conduct sampling in those areas of previous AEC operations that utilized radioactive components at some point during the manufacturing process, in order to evaluate any possible immediate health hazards and to collect sufficient information to determine the next type of survey. The AEC occupied portions of IAAAP from 1947 to 1975 to assemble nuclear weapons. The surveyed areas were identified through interviews with current and former IAAAP employees who had worked at the plant during AEC's tenure, and from AEC records.

    1988-01-01

    Periodic assessments of water use in Iowa are needed to understand and manage the demands for the available water resources. This report summarizes where, how much, and for what purposes water was used in Iowa during 1985. The data are presented for the following categories: agricultural, self-supplied commercial, self-supplied domestic, self-supplied industrial, irrigation, mining, power generation (excluding hydroelectric plants), and public-water supply. The water-use data are further categorized by county, hydrologic unit subregion, and major aquifer system. During 1985, a total of 1,010,000 million gallons was estimated to have been withdrawn from Iowa's surface- and ground-water resources. Of this, 76 percent was withdrawn from surface-water sources and 24 percent from ground-water sources. Power generation was the largest water-use category, withdrawing 66 percent of the total withdrawals; 99 percent was from surface-water sources. Public-water supply was the second largest water-use category and accounted for 13 percent of total withdrawals; 74 percent was from ground-water sources. Self-supplied industries withdrew 7 percent of the total water use and agricultural withdrawals were 6 percent of the total water use. The remaining 8 percent was accounted for by irrigation (3 percent), self-supplied domestic (2 percent), mining (2 percent), and self-supplied commercial (1 percent) water users. The largest estimated water use occurred in Woodbury County where 201,000 million gallons was withdrawn. Pottawattamie County had the second largest water use with 182,000 million gallons. Other counties with significant withdrawals were Allamakee (74,900 million gallons), Muscatine (63,900 million gallons), and Clinton (62,300 million gallons). Power generation plants are in each of these counties. Surface-water withdrawals were most intensive along the Mississippi and Missouri Rivers. Nearly 80 percent of the surface water used in the State was by power generation

    To determine whether Iowa's license restriction program identifies older drivers who appear to be at greater crash risk and to assess compliance with license restrictions. A total of 522 drivers 70 and older who were attempting to renew their driver's licenses at licensing offices in Iowa participated in two telephone surveys: one shortly after renewal to discuss driving before renewal and another 6months later to assess any changes. Surveys assessed driving behavior, crashes, and violations as well as self-reported visual impairments, prescription medications, and physical mobility limitations. Of the 522 drivers, 232 renewed their licenses without having to take a road test (Group 1), and 290 were required to take a road test; of the drivers taking a road test, 191 renewed without restrictions (Group 2), 93 received restrictions (Group 3), and 6 had their licenses suspended (Group 4). The small number of drivers with suspensions precluded including this group in analyses. There were clear distinctions among drivers in the first three groups at the initial survey. Driver age increased across Groups 1-3, as did some visual impairments, number of prescription medications, and physical mobility limitations. Many drivers who received restrictions (Group 3) already were driving fewer miles than drivers in Groups 1-2, and were driving less often at night and on high-speed roads. Following license renewal, reported average weekly mileage decreased more among drivers with license restrictions (Group 3) (36%) than among drivers without restrictions (Groups 1-2) (4% each). For all license restriction types (headlight, geographic area, or speed), decreases in the likelihood of driving during these restricted conditions were greater for drivers with the relevant restrictions than without. Most drivers complied with restrictions. Iowa's license restriction program identifies drivers with more self-reported visual impairments, prescription medications, and physical mobility

Survival of eastern wild turkey poults (M. g. silvestris) 0-4 weeks posthatch was studied in southcentral Iowa during 1994-97. Survival estimates of poults were calculated based on biweekly flush counts and daily locations acquired via radiotelemetry. Poult survival averaged 0.52 ?? 0.14% (?? ?? SE) for telemetry counts and 0.40 ?? 0.15 for flush counts. No within-year or across-year differences were detected between estimation techniques. More than 72% (n = 32) of documented poult mortality occurred ???14 days posthatch, and mammalian predation accounted for 92.9% of documented mortality. If mortality agents are not of concern, we suggest biologists conduct 4-week flush counts to obtain poult survival estimates for use in population models and development of harvest recommendations.

    This report summarizes where, how much and for what purpose water is allocated for use in Iowa with permits issued by the Department of Water, Air and Waste Management. In Iowa, from a total permitted water use of 855,175.45 million gallons per year, about 58 percent is from surface-water sources and about 42 percent is from ground-water sources. Streams are 80.5 percent of the total surface-water use and wells make up 80.1 percent of the total ground-water use, with 65.4 percent of ground water coming from surficial aquifers. Power generation is the use category that is permitted the largest amount of total water use, 46.6 percent, with surface water being the source of 96.7 percent and 77.9 percent of the surface water is from streams. The public water suppliers' category is the next largest use type with 15.7 percent of the total permitted water. Ground water constitutes 74.4 percent of the public water supplier category with 51.7 percent from surficial aquifers. Surface water makes up 25.6 percent of this category with 83.0 percent of the surface water withdrawn from streams. Mining comprises 13.4 percent of the total water use and is the third largest water-use category. Ground water is the source of 63.3 percent of permitted mining water use with 94.3 percent of this from quarries and sand and gravel pits. Surface water is the source of 36.7 percent of the permitted mining water use with 97.6 percent from streams. Irrigation is the fourth largest permitted use type using 12.0 percent of the total water use. Eighty-eight percent of irrigation is from ground-water sources where surficial aquifers account for 94.7 percent. Streams are 81.1 percent of irrigational surface-water use. Self-supplied industrial users are permitted 10.6 percent of the total permitted water use with 85.5 percent of this from ground-water sources and 14.5 percent from surface-water sources. Of the self-supplied industrial ground-water use, 47.9 percent comes from surficial aquifers and

    The Department of Energy is developing an estimate of the undeveloped hydropower potential in this country. The Hydropower Evaluation Software is a computer model that was developed by the Idaho National Engineering Laboratory for this purpose. The software measures the undeveloped hydropower resources available in the United States, using uniform criteria for measurement. The software was developed and tested using hydropower information and data provided by the Southwestern Power Administration. It is a menu-driven software program that allows the personal computer user to assign environmental attributes to potential hydropower sites, calculate development suitability factors for each site based on the environmental attributes present, and generate reports based on these suitability factors. This report details the resource assessment results for the State of Iowa.

    Van Allen, James A.

    On November 1, three distinguished faculty members of the Department of Physics and Astronomy at the University of Iowa were among the victims of a murderous assault.Each of these individuals was at the height of his professional career. Each was devoted to teaching and advising students at all academic levels ranging from undergraduate freshmen to doctoral candidates and postdoctoral associates. Each was of national and international stature. All were specializing in the study of complex properties of ionized gases or plasma, the so-called fourth state of matter. This field is known technically as theoretical plasma physics. It is estimated that over 99% of matter in the universe is in the form of plasma—hence its central importance in the upper atmospheres and magnetospheres of planets, the Sun, the interplanetary medium, and in almost all large astrophysical systems.

    The overarching objective of NASA Global Precipitation Measurement Mission (GPM) integrated hydrologic ground validation (GV) is to provide a better understanding of the strengths and limitations of the satellite products, in the context of hydrologic applications. Accordingly, the NASA GPM GV program recently completed the first of several hydrology-oriented field efforts: the Iowa Flood Studies (IFloodS) experiment. IFloodS was conducted in central Iowa during the months of April-June, 2013. IFloodS science objectives focused on: a) The collection of reference multi-parameter radar, rain gauge, disdrometer, soil moisture, and hydrologic network measurements to quantify the physical character and space/time variability of rain (e.g., rates, drop size distributions, processes), land surface- state and hydrologic response; b) Application of the ground reference measurements to assessment of satellite-based rainfall estimation uncertainties; c) Propagation of both ground and satellite rainfall estimation uncertainties in coupled hydrologic prediction models to assess impacts on predictive skill; and d) Evaluation of rainfall properties such as rate and accumulation relative to basin hydrologic characteristics in modeled flood genesis. IFloodS observational objectives were achieved via deployments of the NASA NPOL S-band and D3R Ka/Ku-band dual-polarimetric radars (operating in coordinated scanning modes), four University of Iowa X-band dual-polarimetric radars, four Micro Rain Radars, a network of 25 paired rain gauge platforms with attendant soil moisture and temperature probes, a network of six 2D Video and 14 Parsivel disdrometers, and 15 USDA-ARS rain gauge and soil-moisture stations (collaboration with the USDA-ARS and NASA Soil Moisture Active-Passive mission). The aforementioned platforms complemented existing operational WSR-88D S-band polarimetric radar, USGS streamflow, and Iowa Flood Center-affiliated stream monitoring and rainfall measurements.

    This Memorandum of Understanding requests beam time at Fermilab during the Winter 2005-2006 Meson Test Run to measure the signal size from various configurations of Cerenkov light generators and phototubes. The University of Iowa has pioneered in application of Cerenkov radiation for high-energy detectors. One of the results of this effort is the huge forward calorimeter for CMS (at the LHC) with a half million quartz fibers in iron. The laboratory plans to use this expertise to develop a variety of detectors making use of Cerenkov light and phototubes as the active elements in calorimeters for high-energy particles. There are three immediate applications related to forward angle calorimeters in CMS; ZDC, CASTOR, and the HE upgrade. The University of Iowa will make the detailed design for the Zero Degree Calorimeter. The proposed design uses tungsten plates interleaved with sheets of quartz fibers. In the EM part the plates are perpendicular to the beam, in the rear hadronic part they are at an angle of 45{sup o}. Because of the limited cross sectional area of the plates, there will be considerable leakage of shower particles out of the four sides. We plan to measure this leakage and compare the results with simulations. The leakage will be measured by placing a polished aluminum tank, 4 in wide, 20 in long and 8 in deep on top of absorber material made of blocks of tantalum and copper. The fluid in the tank, that generates the Ccrcnkov light, could be water; but ethylene glycol (antifreeze, but without the added color) would be better. Being non-polar, it is not corrosive like water, and it has a higher index of refraction, 1.42 vs. 1.33. The larger index of refraction would result in more Cerenkov light and better coupling to the PMT. The University of Iowa has been asked to design the light guides for CASTOR that take the light from the quartz plates, in which the light is produced, and carry it to the PMTs. These plates, interleaved with tungsten plates, are

    Downey, E. C.; Mutel, R. L.

    We describe a CCD-based automated telescope system in operation at the University of Iowa. Observers initiate observing programs using a simple free-format scripting language for preparing observing requests. The schedule file describes sources, durations, filters and other observing parameters. A telescope scheduling program generates an ordered master observing list for a given night based on priority telescope control daemon then reads the sorted schedule file and issues commands to the hardware control daemons. All CCD images are calibrated (bias, thermal, flat) by default and pattern matched to the Guide Star Catalog, with accurate WCS coordinates written to the FITS header. Additional post-processing tools include an interactive image display and analysis program which supports photometry and astrometry, batch tools to automate supernova searches and time-sequenced photometry, and a stand-alone world coordinate calibration tool. Additional details are available {http://inferno.physics.uiowa.edu} on the WWW.

  12. Iowa Flood Center Model Performance Evaluation

    Quintero, F.; Krajewski, W. F.; Mantilla, R.; Seo, B. C.

    2016-12-01

    We evaluated the performance of a hydrologic model which produces real-time flow forecasts. The model was developed by the Iowa Flood Center (IFC) and it is implemented operationally to produce streamflow forecast for the communities of the state of Iowa in the United States. The model parameters are calibration-free. It has a parsimonious structure that reproduces the more significant processes involved in the transformation from rainfall to runoff. The operational model uses a rainfall forcing produced by IFC, derived from the combination of rainfall fields of seven NEXRAD radars. This rainfall forcing does not include bias adjustment from rain gauges, due to the non-existence of a raingage network that enable the correction in real-time. Therefore, the model was also evaluated using the bias-adjusted rainfall product Stage IV. We used six years of IFC rainfall and Stage IV to evaluate the performance of the hydrologic model and the sensitivity of the flow simulations to the model input. The model was not calibrated to any particular rainfall product. The distributed structure of the model allows obtaining results at any channel of the drainage network. We produced simulated hydrographs at about 140 locations with different sub-basin spatial scales, where USGS streamflow observations are available. We compared flow simulations to observations and obtained several metrics of error including Nash Sutcliffe efficiency, normalized root mean square error, volume error and time to peak error. We also evaluated the number of occurrences of hits and false alarms of discharge forecasts exceeding flood stage.

    In the Agricultural Health Study, information on participant live births was largely provided by female partners of male private applicators. At the Iowa site, such information was available for 13,599 (42.9%) of 31,707 applicators. To improve identification of live births among Iowa participants, we used a probabilistic and deterministic approach to link available demographic data from 31,707 households and information on live births from 13,599 households with 1,014,916 Iowa birth certificates. Record linkage identified 16,611 (93.7%) of 17,719 reported live births and 17,883 additional live births, most (14,411 or 80.6%) not reported due to nonresponse by female partners. This record linkage produced an expanded cohort of live-born children among Iowa participants, which will facilitate improved study of the effects of agricultural exposures, including pesticides, on selected birth outcomes and childhood disease.

    The purpose of this study is to examine and compare the amount of inter-speaker variability in the articulation of monozygotic twin pairs (MZ), dizygotic twin pairs (DZ), and pairs of unrelated twins with the goal of examining in greater depth the influence of physiology on articulation. Physiological parameters are assumed to be very similar in MZ twin pairs in contrast to DZ twin pairs or unrelated speakers, and it is hypothesized that the speaker specific shape of articulatory looping trajectories of the tongue is at least partly dependent on biomechanical properties and the speaker's individual physiology. By means of electromagnetic articulography (EMA), inter-speaker variability in the looping trajectories of the tongue back during /VCV/ sequences is analyzed. Results reveal similar looping patterns within MZ twin pairs but in DZ pairs differences in the shape of the loop, the direction of the upward and downward movement, and the amount of horizontal sliding movement at the palate are found.

    The length of the vocal tract is correlated with speaker size and, so, speech sounds have information about the size of the speaker in a form that is interpretable by the listener. A wide range of different vocal tract lengths exist in the population and humans are able to distinguish speaker size from the speech. Smith et al. [J. Acoust. Soc. Am. 117, 305–318 (2005)] presented vowel sounds to listeners and showed that the ability to discriminate speaker size extends beyond the normal range of speaker sizes which suggests that information about the size and shape of the vocal tract is segregated automatically at an early stage in the processing. This paper reports an extension of the size discrimination research using a much larger set of speech sounds, namely, 180 consonant-vowel and vowel-consonant syllables. Despite the pronounced increase in stimulus variability, there was actually an improvement in discrimination performance over that supported by vowel sounds alone. Performance with vowel-consonant syllables was slightly better than with consonant-vowel syllables. These results support the hypothesis that information about the length of the vocal tract is segregated at an early stage in auditory processing. PMID:16419826

    Effective field understanding of soils is crucial. This is true everywhere but especially so in Iowa, a 15 million hectare state in the central USA's "corn belt." Iowa is intensely farmed and almost exclusively privately owned. Many regions of Iowa have had over 90% of their land area in row crops for the past 60 years. In these regions two very common land management strategies are tile drainage (1.5 million km total) and high rates of fertilization (e.g., 200 kg N/ha-yr for cropland) Iowa also has problematic environmental issues including high rates of erosion, excessive sediment and nutrient pollution in water bodies and episodic catastrophic floods. Given the preceding the Agronomy, Environmental Science and Sustainable Agriculture programs at Iowa State University (ISU) offer a strong suite of soil science classes - undergraduate through graduate. The objective of this presentation is to review selected field based soil science courses offered by those programs. This review includes contrasting and comparing campus-based and immersion classes. Immersion classes include ones offered at Iowa Lakeside Laboratory, as "soil judging" and internationally. Findings over the past 20 years are consistent. Students at all levels gain soil science knowledge, competency and confidence proportional to the amount of time spent in field activities. Furthermore their professional skepticism is sharpened. They are also preferentially hired even in career postings that do not require fieldwork. In other words, field learning results in better soil science professionals who have highly functional and sought after knowledge.

  4. The kinesthetic speaker. Putting action into words.

    PubMed

    Morgan, N

    2001-04-01

    Speeches and presentations offer an interesting catch-22: executives don't want to spend long hours creating them, and people don't want to sit for long hours listening to them. Ultimately, though, executives can't live without them. That's because a good speech or presentation has the power to inspire people to act on the speaker's behalf and create change. Author Nick Morgan, a longtime speech-writer and speaking coach, says what's most often lacking in today's speeches and presentations is what he calls the "kinesthetic connection." Many good speakers connect aurally with their audiences, telling dramatic stories and effectively pacing their speeches to hold people's attention. Others connect visually, with a vivid film clip or a killer slide. Some people do both, but not many also connect kinesthetically. Morgan says the kinesthetic speaker feeds an audience's primal hunger to experience a presentation on a physical, as well as an intellectual, level. Through awareness of their own physical presence--gestures, posture, movements--and through the effective use of the space in which they present, kinesthetic speakers can create potent nonverbal messages that reinforce their verbal ones. In this article, Morgan describes techniques for harnessing kinesthetic power and creating a sense of intimacy with an audience--a closeness that is more widely expected from speakers since the advent of television. For instance, kinesthetic speakers should make use of audience proxies--individuals in the crowd who serve as representatives for the others. Ultimately, the author says, a speech or presentation offers something of great value to business executives: it's the best vehicle for winning trust from large groups of people--be they employees, colleagues, or share-holders.

  5. Perception of pitch location within a speaker's range: fundamental frequency, voice quality and speaker sex.

    PubMed

    Bishop, Jason; Keating, Patricia

    2012-08-01

    How are listeners able to identify whether the pitch of a brief isolated sample of an unknown voice is high or low in the overall pitch range of that speaker? Does the speaker's voice quality convey crucial information about pitch level? Results and statistical models of two experiments that provide answers to these questions are presented. First, listeners rated the pitch levels of vowels taken over the full pitch ranges of male and female speakers. The absolute f0 of the samples was by far the most important determinant of listeners' ratings, but with some effect of the sex of the speaker. Acoustic measures of voice quality had only a very small effect on these ratings. This result suggests that listeners have expectations about f0s for average speakers of each sex, and judge voice samples against such expectations. Second, listeners judged speaker sex for the same speech samples. Again, absolute f0 was the most important determinant of listeners' judgments, but now voice quality measures also played a role. Thus it seems that pitch level judgments depend on voice quality mostly indirectly, through its information about sex. Absolute f0 is the most important information for deciding both pitch level and speaker sex.

    Many studies have described and analyzed the singer's formant. A similar phenomenon produced by trained speakers led some authors to examine the speaker's ring. If we consider these phenomena as resonance effects associated with vocal tract adjustments and training, can we hypothesize that trained singers can carry over their singing formant ability into speech, also obtaining a speaker's ring? Can we find similar differences for energy distribution in continuous speech? Forty classically trained singers and forty untrained normal speakers performed an all-voiced reading task and produced a sample of a sustained spoken vowel /a/. The singers were also requested to perform a sustained sung vowel /a/ at a comfortable pitch. The reading was analyzed by the long-term average spectrum (LTAS) method. The sustained vowels were analyzed through power spectrum analysis. The data suggest that singers show more energy concentration in the singer's formant/speaker's ring region in both sung and spoken vowels. The singers' spoken vowel energy in the speaker's ring area was found to be significantly larger than that of the untrained speakers. The LTAS showed similar findings suggesting that those differences also occur in continuous speech. This finding supports the value of further research on the effect of singing training on the resonance of the speaking voice.

Major ions, nitrogen and other nutrients, and pesticides and some of their breakdown compounds were analyzed in both surface and ground water. Biological communities that included fish, invertebrates, and algae, were described in relation to stream water quality. Volatile organic compounds that originate from fuels, solvent, and industry were analyzed from ground-water samples. Agricultural and urban land-use effects on shallow ground-water compared and contrasted.

  8. Speaker normalization for chinese vowel recognition in cochlear implants.

    2005-07-01

    Because of the limited spectra-temporal resolution associated with cochlear implants, implant patients often have greater difficulty with multitalker speech recognition. The present study investigated whether multitalker speech recognition can be improved by applying speaker normalization techniques to cochlear implant speech processing. Multitalker Chinese vowel recognition was tested with normal-hearing Chinese-speaking subjects listening to a 4-channel cochlear implant simulation, with and without speaker normalization. For each subject, speaker normalization was referenced to the speaker that produced the best recognition performance under conditions without speaker normalization. To match the remaining speakers to this "optimal" output pattern, the overall frequency range of the analysis filter bank was adjusted for each speaker according to the ratio of the mean third formant frequency values between the specific speaker and the reference speaker. Results showed that speaker normalization provided a small but significant improvement in subjects' overall recognition performance. After speaker normalization, subjects' patterns of recognition performance across speakers changed, demonstrating the potential for speaker-dependent effects with the proposed normalization technique.

  9. The predictability of Iowa's hydroclimate through analog forecasts

    NASA Astrophysics Data System (ADS)

    Rowe, Scott Thomas

    Iowa has long been affected by periods characterized by extreme drought and flood. In 2008, Cedar Rapids, Iowa was devastated by a record flood with damages around 3 billion. Several years later, Iowa was affected by severe drought in 2012, causing upwards of 30 billion in damages and losses across the United States. These climatic regimes can quickly transition from one regime to another, as was observed in the June 2013 major floods to the late summer 2013 severe drought across eastern Iowa. Though it is not possible to prevent a natural disaster from occurring, we explore how predictable these events are by using forecast models and analogs. Iowa's climate records are analyzed from 1950 to 2012 to determine if there are specific surface and upper-air pressure patterns linked to climate regimes (i.e., cold/hot and dry/wet conditions for a given month). We found that opposing climate regimes in Iowa have reversed anomalies in certain geographical regions of the northern hemisphere. These defined patterns and waves suggested to us that it could be possible to forecast extreme temperature and precipitation periods over Iowa if given a skillful forecast system. We examined the CMC, COLA, and GFDL models within the National Multi-Model Ensemble suite to create analog forecasts based on either surface or upper-air pressure forecasts. The verification results show that some analogs have predictability skill at the 0.5-month lead time exceeding random chance, but our overall confidence in the analog forecasts is not high enough to allow us to issue statewide categorical temperature and precipitation climate forecasts.

    2012-01-01

    Equivocal evidence exists regarding the degree of cognitive stability and prevalence of cognitive impairment in very late life. The objective of the current study was to examine mental status performance and change over time within a sample of Iowa centenarians. The baseline sample consisted of 152 community-dwelling and institutionalized centenarians. Twenty eight of these centenarians participated in the next phase of the study which involved up to four subsequent assessments conducted over a 6-month period. Centenarians' Short Portable Mental Status Questionnaire (SPMSQ; Pfeiffer, 1975) performance indicated that 40% of the baseline sample performed within the normal range while an additional 40% of centenarians' performed within the moderately or severely impaired range. Examination of individual-level change indicated four patterns of short-term longitudinal performance which depicted stability, enhancement, decrement, and variability in scores across the 8-month testing period. The degree of reliable change as assessed by standard error of measurement largely mirrored change as classified by the traditional scoring categories, however, the former approach appeared more sensitive to meaningful intraindividual change in later assessments.

    Background Somatic Marker Hypothesis (SMH), based on clinical observations, delineates neuronal networks for interpreting consciousness generation and decision-making. The Iowa gambling task (IGT) was designed to verify the SMH. However, more and more behavioral and brain imaging studies had reported incongruent results that pinpointed a need to re-evaluate the central representations of SMH. The current study used event-related fMRI (functional Magnetic Resonance Imaging) to examine neural correlates of anticipation vs. outcome, wins vs. losses, and differential decks' contingencies of IGT. Results Behavioral results showed a prominent effect of frequency in driving choices. The insula and basal ganglia were activated during the anticipation phase while the inferior parietal lobule was activated during the outcome phase. The activation of medial prefrontal cortex was especially targeted during the high punishment contingencies. The data suggest that under uncertainty the normal decision makers can become myopic. Conclusion The insula and basal ganglia might play a vital role in long-term guidance of decision-making. Inferior parietal lobule might participate in evaluating the consequence and medial prefrontal cortex may service the function of error monitoring. PMID:18655719

  5. Speaker recognition through NLP and CWT modeling.

    SciTech Connect

    Brown-VanHoozer, A.; Kercel, S. W.; Tucker, R. W.

    1999-06-23

    The objective of this research is to develop a system capable of identifying speakers on wiretaps from a large database (>500 speakers) with a short search time duration (<30 seconds), and with better than 90% accuracy. Much previous research in speaker recognition has led to algorithms that produced encouraging preliminary results, but were overwhelmed when applied to populations of more than a dozen or so different speakers. The authors are investigating a solution to the ''huge population'' problem by seeking two completely different kinds of characterizing features. These features are extracted using the techniques of Neuro-Linguistic Programming (NLP) and the continuous wavelet transform (CWT). NLP extracts precise neurological, verbal and non-verbal information, and assimilates the information into useful patterns. These patterns are based on specific cues demonstrated by each individual, and provide ways of determining congruency between verbal and non-verbal cues. The primary NLP modalities are characterized through word spotting (or verbal predicates cues, e.g., see, sound, feel, etc.) while the secondary modalities would be characterized through the speech transcription used by the individual. This has the practical effect of reducing the size of the search space, and greatly speeding up the process of identifying an unknown speaker. The wavelet-based line of investigation concentrates on using vowel phonemes and non-verbal cues, such as tempo. The rationale for concentrating on vowels is there are a limited number of vowels phonemes, and at least one of them usually appears in even the shortest of speech segments. Using the fast, CWT algorithm, the details of both the formant frequency and the glottal excitation characteristics can be easily extracted from voice waveforms. The differences in the glottal excitation waveforms as well as the formant frequency are evident in the CWT output. More significantly, the CWT reveals significant detail of the

    1989-01-01

    A study was made of possible hazardous working conditions at Iowa Industrial Hydraulics, Pocahontas, Iowa. About 140 production workers were employed in manufacturing hydraulic pumps. The major exposures investigated were to nine different types of cutting fluids with their biocides, the solvent-based floor cleaner Marvella, mineral spirits, two hand cleaners, oils used for the lubrication of machines, and metal chippings. Most machines were supplied with coolant from a central system. There was no mechanism in place to clean the coolant and no regular monitoring was conducted for coolant concentration, pH, or bacterial or fungal counts. Workers had experienced an outbreak of dermatitis in September 1986 at which time the coolant in most machines had become dense, brown, and had a foul odor. Sampling revealed the coolant to be ten times more concentrated than it should have been and contaminated with lubricating oils. Medical histories, patch tests, and questionnaires were used to obtain data from the workers. The report concludes that workers exposed to Lubrisyn-plus with its biocide Ducide-20, or Trim-sol, or to Marvella had a significantly higher risk of developing dermatitis. Specific measures for fluid maintenance, employee education, hazard communication, and personal protection are recommended.

  11. Assessment practices of Iowa science teachers from a constructivist perspective

    NASA Astrophysics Data System (ADS)

    Harris Freedman, Robin Lee

    How do students learn? What can they do? When assessments evolve out of instruction as is expected in inquiry and constructivist based classrooms, one can derive definitive results. It was the purpose of this study to describe the assessment environment found in the Iowa SS&C compared to those in other Iowa science classrooms. Science instruction in classrooms of Iowa SS&C teachers is based on NSES, Constructivist theory, and an STS approach. In Iowa SS&C classrooms the primary focus is to make science personal and relevant to students. Iowa science teachers were surveyed. Survey results revealed that the two groups of teachers had different perceptions regarding their grading philosophies and in the use of traditional and non-traditional assessments. The two groups were similar in their ability to identify appropriate uses for assessments and the use of a variety of assessments that make up a student's grade. Several methods were used to gain understanding of how the two teacher groups were different, i.e., in-depth interviews, a collection of assessment artifacts, and a student survey of a sub-sample of teachers. Artifact analysis revealed that the Iowa SS&C teachers used more application items, were more familiar and more likely to use non-traditional assessments, and used more assessments of higher order thinking skills than other Iowa science teachers. Student perspectives regarding assessments were surveyed. Students who completed the survey felt competent to assess themselves. Iowa SS&C students perceived that they have an active role in establishing the classroom assessment environment, share and listen to each others' ideas, and have a voice in how and by what means they are assessed. Synthesis of interview data revealed an assessment environment that reflected NSES philosophy and the STS approach. The assessment environment according to Iowa SS&C teachers was defined by teacher beliefs and practices, how teachers engage students, and internal and external

    Researchers, engineers, and students at the Iowa Flood Center (IFC) have designed, built, deployed, and maintained a network of river stage sensors. The network consists of 120+ (and growing) sensors deployed across Iowa. The impetus for this endeavor was the unprecedented and devastating floods Iowa experienced in 2008. The sensors measure river stage using a commercial ultrasonic distance module. The sensors are mounted on bridges, powered by solar panels, and make river stage measurements every 15 minutes, which are transmitted via cell phones to IFC servers on the internet. At the servers, the data are ingested into relational databases and made available to researchers and the general public in real-time via the IFC flood information system (IFIS). IFIS provides a very convenient map-based view of the river stage measurement along with a wealth of other relevant information. The Iowa Department of Transportation (DOT) and the Iowa Department of Natural Resources (DNR) are keenly interested in the bridge-mounted sensors, and have helped fund their development and deployment. The sensors are relatively inexpensive and complement existing USGS discharge station measurements.

    2004-12-01

    This paper presents an overview of a state-of-the-art text-independent speaker verification system. First, an introduction proposes a modular scheme of the training and test phases of a speaker verification system. Then, the most commonly speech parameterization used in speaker verification, namely, cepstral analysis, is detailed. Gaussian mixture modeling, which is the speaker modeling technique used in most systems, is then explained. A few speaker modeling alternatives, namely, neural networks and support vector machines, are mentioned. Normalization of scores is then explained, as this is a very important step to deal with real-world data. The evaluation of a speaker verification system is then detailed, and the detection error trade-off (DET) curve is explained. Several extensions of speaker verification are then enumerated, including speaker tracking and segmentation by speakers. Then, some applications of speaker verification are proposed, including on-site applications, remote applications, applications relative to structuring audio information, and games. Issues concerning the forensic area are then recalled, as we believe it is very important to inform people about the actual performance and limitations of speaker verification systems. This paper concludes by giving a few research trends in speaker verification for the next couple of years.

    2015-03-01

    Between-speaker variability of acoustically measurable speech rhythm [%V, ΔV(ln), ΔC(ln), and Δpeak(ln)] was investigated when within-speaker variability of (a) articulation rate and (b) linguistic structural characteristics was introduced. To study (a), 12 speakers of Standard German read seven lexically identical sentences under five different intended tempo conditions (very slow, slow, normal, fast, very fast). To study (b), 16 speakers of Zurich Swiss German produced 16 spontaneous utterances each (256 in total) for which transcripts were made and then read by all speakers (4096 sentences; 16 speaker × 256 sentences). Between-speaker variability was tested using analysis of variance with repeated measures on within-speaker factors. Results revealed strong and consistent between-speaker variability while within-speaker variability as a function of articulation rate and linguistic characteristics was typically not significant. It was concluded that between-speaker variability of acoustically measurable speech rhythm is strong and robust against various sources of within-speaker variability. Idiosyncratic articulatory movements were found to be the most plausible factor explaining between-speaker differences.

  15. Occurrence, distribution, and transport of nutrients in Eastern Iowa Rivers

    USGS Publications Warehouse

    Becher, Kent D.

    2001-01-01

    Total nitrogen loads contributed to the Mississippi River from the Eastern Iowa Basins during 1996, 1997, and 1998 were 97,000, 120,000, and 230,000 metric tons respectively. Total phosphorus loads contributed to the Mississippi River from the Eastern Iowa Basins during 1996, 1997, and 1998 were 6,900, 4,600, and 8,800 metric tons, respectively. The highest nitrogen and phosphorus yields typically occurred in streams draining small watersheds that were dominated by a single land use and geology. Sampling sites located in drainage basins with higher row-crop percentage typically had higher nitrogen and phosphorus yields. Sites that were located in the Des Moines Lobe and the Southern Iowa Drift Plain typically had higher phosphorus yields probably due to more erodible soils and steeper slopes.

  16. Contraction scour at a bridge over the Iowa River

    USGS Publications Warehouse

    Fischer, Edward E.

    1994-01-01

    Flooding of the Iowa River during July and August 1993 caused extensive contraction scour at the State Highway 99 bridge over the Iowa River at Wapello, Iowa. At least 3.3 m of piling under the footing of the second pier from the right (west) abutment were exposed. The scoured streambed did not fill in again after the flood receded, and a bathymetric survey in November 1993 showed that the streambed had been scoured for a distance of about 500 m upstream from the bridge. The bridge was closed to traffic, first because of water over the roadway when a levee failed, and then remained closed because of the exposed piling. The bridge subsequently was reopened to traffic with a weight limit of 13.6 tons.

  17. Physiological responses at short distances from a parametric speaker.

    PubMed

    2012-06-13

    In recent years, parametric speakers have been used in various circumstances. In our previous studies, we verified that the physiological burden of the sound of parametric speaker set at 2.6 m from the subjects was lower than that of the general speaker. However, nothing has yet been demonstrated about the effects of the sound of a parametric speaker at the shorter distance between parametric speakers the human body. Therefore, we studied this effect on physiological functions and task performance. Nine male subjects participated in this study. They completed three consecutive sessions: a 20-minute quiet period as a baseline, a 30-minute mental task period with general speakers or parametric speakers, and a 20-minute recovery period. We measured electrocardiogram (ECG) photoplethysmogram (PTG), electroencephalogram (EEG), systolic and diastolic blood pressure. Four experiments, one with a speaker condition (general speaker and parametric speaker), the other with a distance condition (0.3 m and 1.0 m), were conducted respectively at the same time of day on separate days. To examine the effects of the speaker and distance, three-way repeated measures ANOVA (speaker factor x distance factor x time factor) were conducted. In conclusion, we found that the physiological responses were not significantly different between the speaker condition and the distance condition. Meanwhile, it was shown that the physiological burdens increased with progress in time independently of speaker condition and distance condition. In summary, the effects of the parametric speaker at the 2.6 m distance were not obtained at the distance of 1 m or less.

  2. Quantification of Knickpoint Migration in Western Iowa

    NASA Astrophysics Data System (ADS)

    Wilson, C. G.; Thomas, J. T.; Papanicolaou, T.; Elhakeem, M.

    2009-12-01

    Knickpoints threaten the stability of bridge structures in Western Iowa, thus the overarching goal of this research was to provide a predictive tool for knickpoint propagation. The study involved detailed field investigations over two years in order to monitor the upstream migration of a knickpoint on Mud Creek in Mills County, IA and identify the key mechanisms triggering knickpoint propagation. A state-of-the-art laser level system mounted on a movable truss provided continuous measurements of the knickpoint front for different flow conditions. A pressure transducer in proximity of the truss provided simultaneous flow depth measurements. The laser and pressure transducer measurements led to the identification of the conditions, at which the knickpoint migration commenced. It is suggested that negative pressures developed by the reverse roller flow near the toe of the knickpoint face triggered undercutting of the knickpoint at this location. The pressure differential between the negative pressure and the atmospheric pressure also pulled the impinging jet closer to the knickpoint face producing scour. In addition, the pressure differential may have induced suction of sediment from the face. Other contributing factors included slump failure, seepage effects, and local fluvial erosion due to the exerted fluid shear. The prevailing flow conditions and soil information along with the channel cross-sectional geometry and gradient were used as inputs to a transcritical, one dimensional, hydraulic/geomorphic numerical model, which was used to map the flow characteristics and shear stress conditions near the knickpoint. Such detailed flow calculations do not exist in the published literature. The coupling of field and modeling work resulted in the development of a blueprint methodology, which can be adopted in different parts of the country for evaluating knickpoint evolution. This information will assist local government agencies in better understanding the principal

  3. The Iowa Chemistry Education Alliance, ICEA: Process and product

    NASA Astrophysics Data System (ADS)

    Burke, Kathleen Annette

    2005-12-01

    The Iowa Chemistry Education Alliance, ICEA, supported by Department of Education Star Schools funding (R203F5000198), was both a Process and a Product. The Process included: (a) Design and support of high school teacher training sessions that incorporated distance learning techniques, cooperative learning and guided inquiry strategies, and a constructivist, student-centered classroom focus; (b) Design and incorporation of eight supplemental learning modules, corresponding assessment rubrics, and supporting videotapes into the existing Iowa high school chemistry curriculum; (c) Adaptation of the learning modules throughout the course of the academic year while the units were being integrated into the existing curriculum; (d) Modification and final editing of the curriculum modules and videotapes. The Product consisted of eight supplemental ICEA learning modules with corresponding assessment rubrics, and three supporting videotapes. To integrate ICEA materials into the existing curriculum, students at high schools around the state of Iowa conducted cooperative, guided-inquiry laboratory exercises. Via electronic mail and Iowa's two-way interactive audio-video system, the Iowa Communications Network (ICN), they discussed strategies for experimentation and shared results obtained. Invited guest experts also visited student groups via the ICN. Teachers conducted regular biannual on-site face-to-face planning meetings. These were augmented and supported by weekly or biweekly "staff" meetings conducted via the ICN. From the original three hundred students in four central Iowa high schools (rural, urban, and suburban), by its third and fourth year, the Project evolved to include over 1500 students in twenty-five high schools statewide.

  4. Formant frequency characteristics of elderly speakers in contextual speech.

    PubMed

    Rastatter, M P; McGuire, R A; Kalinowski, J; Stuart, A

    1997-01-01

    The present study measured F1 and F2 formant frequency levels of elderly and young male and female speakers producing the /i/, /ae/, [symbol: see text], /u/, and /a/ vowels in two carrier phrases. Results of a series of ANOVAs showed significant interactions of speaker age x vowel for both F1 and F2 formant frequencies for the male and female speakers. Results suggested that while elderly male speakers exhibit significant alterations in vowel production during contextual speech, elderly female speakers generally maintain formant frequency integrity or appropriate articulatory posturing during contextual vowel productions.

    2011-03-10

    To evaluate the impact guest speakers have on student development in a professional development seminar series. Over a 5-semester period, presentations were given by 18 guest speakers as part of a professional development seminar series. A 28-item survey instrument was constructed and administered to 68 students to assess the impact of the guest speakers on the students' professional development. Forty-six (68%) students completed the survey instrument, and the results demonstrated the value of the guest speakers, most notably in the areas of career development and professional responsibility. Exposing pharmacy students to guest speakers from varied pharmacy career paths positively impacted students' knowledge of career options and professional development.

    USGS Publications Warehouse

    Lambert, R.B.

    1992-01-01

    The objectives of the ground-water-level monitoring network in Iowa are to provide the data needed to: (1) determine the change in aquifer storage, (2) document the effects of climatic stress and human activities on discharge and recharge to the principal aquifers, (3) quantify the physical characteristics of ground-water flow including the transmissivity, hydraulic conductivity, and specific capacity of aquifers; and (4) provide historical baseline data for future research. The design of the ground-water-level monitoring network in Iowa that satisfies these objectives includes three types of data: (1) hydrologic data, (2) water-management data for use by State and local officials, and (3) baseline data.

    Kukersite samples from Estonia and Iowa were analyzed for elemental composition, functional group distribution, and carbon and hydrogen stable isotope ratios. The elemental and hydrogen isotope values, together with other analytical data, suggest a higher thermal maturity for the Iowa kukersite. The wide carbon isotopic range of 9.3??? among kukersites, with unusually negative ??13C values reaching -33.2???, indicates isotopically variable carbon sources for production of biomass, and thus major paleoceanographic differences between the environments supporting biosynthesis. ?? 2003 Elsevier Ltd.

    Greenberg, Craig S.; Martin, Alvin F.

    2009-05-01

    From 1996 through 2008, the NIST Speaker Recognition Evaluations have focused on the task of automatic speaker detection based on recorded segments of spontaneous conversational speech. Earlier evaluations were limited to English language telephone speech. More recent evaluations (2004-2008) have included some conversational telephone speech in multiple languages, with the 2008 evaluation including 24 different languages. These recent evaluations have also explored cross channel effects by including phone conversations recorded over multiple microphone channels, and the 2008 evaluation also examined interview type speech recorded over multiple microphone channels. The considerable progress observed over the period of these evaluations has made the technology potentially useful for detecting individuals of interest in certain applications. Performance capability is measurably affected by a number of situational factors, including the number and duration of the training speech segments available, the durations of the test speech segments available, the language(s) spoken in these segments, and the types and variability of the recording channels involved.

  9. Vocal caricatures reveal signatures of speaker identity

    PubMed Central

    López, Sabrina; Riera, Pablo; Assaneo, María Florencia; Eguía, Manuel; Sigman, Mariano; Trevisan, Marcos A.

    2013-01-01

    What are the features that impersonators select to elicit a speaker's identity? We built a voice database of public figures (targets) and imitations produced by professional impersonators. They produced one imitation based on their memory of the target (caricature) and another one after listening to the target audio (replica). A set of naive participants then judged identity and similarity of pairs of voices. Identity was better evoked by the caricatures and replicas were perceived to be closer to the targets in terms of voice similarity. We used this data to map relevant acoustic dimensions for each task. Our results indicate that speaker identity is mainly associated with vocal tract features, while perception of voice similarity is related to vocal folds parameters. We therefore show the way in which acoustic caricatures emphasize identity features at the cost of loosing similarity, which allows drawing an analogy with caricatures in the visual space.

    McCarthy, Kathleen A.; Rose, Claire E.; Kalkhoff, Stephen J.

    2012-01-01

    Studies of the transport and fate of agricultural chemicals in different environmental settings were conducted by the U.S. Geological Survey (USGS) National Water-Quality Assessment (NAWQA) Program's Agricultural Chemicals Team (ACT) at seven sites across the Nation, including the South Fork Iowa River basin in central Iowa and the Bogue Phalia basin in northwestern Mississippi. The South Fork Iowa River basin is representative of midwestern agriculture, where corn and soybeans are the predominant crops and a large percentage of the cultivated land is underlain by artificial drainage. The Bogue Phalia basin is representative of corn, soybean, cotton, and rice cropping in the humid, subtropical southeastern United States. Details of the environmental settings of these basins and the data-collection activities conducted by the USGS ACT over the 2006-10 study period are described in this report.

    Mahlstede, J. P.; Carlson, R. E.; Thomson, G. W. (Principal Investigator)

    1973-01-01

    The author has identified the following significant results. Results of the continuing analysis of ERTS-1 imagery covering Iowa during 1972 and periods during 1973 are covered. Emphasis is placed on the identification and classification of major crop types at two test sites in Iowa. Standard photointerpretive methods were used in this analysis including the direct enlargement of black and white single-band products and additive color multi-band procedures using a miniadcol system. The use of sequential coverage during the crop growing season is emphasized as a means to improve the effectiveness of ERTS-1 photointerpretations of crop land acreage estimates in Iowa. Illustrative black and white and color prints of both ERTS-1 and underflight imagery are included. In addition, forest land inventories at one test site are reported. A new method for the inventory of forest lands using ERTS-1 imagery is reported and compared with estimates obtained using earlier underflight imagery.

  12. How Cognitive Load Influences Speakers' Choice of Referring Expressions.

    PubMed

    Vogels, Jorrig; Krahmer, Emiel; Maes, Alfons

    2015-08-01

    We report on two experiments investigating the effect of an increased cognitive load for speakers on the choice of referring expressions. Speakers produced story continuations to addressees, in which they referred to characters that were either salient or non-salient in the discourse. In Experiment 1, referents that were salient for the speaker were non-salient for the addressee, and vice versa. In Experiment 2, all discourse information was shared between speaker and addressee. Cognitive load was manipulated by the presence or absence of a secondary task for the speaker. The results show that speakers under load are more likely to produce pronouns, at least when referring to less salient referents. We take this finding as evidence that speakers under load have more difficulties taking discourse salience into account, resulting in the use of expressions that are more economical for themselves. © 2014 Cognitive Science Society, Inc.

  13. Aircraft interior ANC with flat panel speakers

    NASA Astrophysics Data System (ADS)

    Gerner, Christian; Sachau, Delf; Breitbach, Harald

    2004-07-01

    In propeller driven aircraft the main source for internal noise are tonal disturbances caused by the propeller blades that are passing the fuselage. In a certain four propeller military transport aircraft the maximum sound level in the cabin can reach up to 110 dB(A), not taking into account any noise control treatments. Inside the semi closed loadmaster working station (LMWS) the sound level must be reduced down to 86 dB(A). It is proposed to reach this goal with an active noise control system, because passive solutions are to heavy at low frequencies. Optimal positions of the loudspeakers are found by finite element calculations. These positions have been realized in a full-scale test bed. A reduction of the sound pressure level of more than 30dB within a specified volume was achieved at a frequency of 100 Hz. HiFi speakers are used as secondary actuators in this test bed. These speakers are heavy and have unsuitable geometric dimensions for an aircraft. Therefore, other actuators, e.g. flat panel speakers, will be investigated with respect to the application in a mock-up of the LMWS.

  14. Assessment of variation between and within speakers

    NASA Astrophysics Data System (ADS)

    Bahr, Ruth Huntley

    2003-10-01

    While few individuals would argue that vocal cues can signal a person's identity, it is difficult to specify exactly which parameter(s) provide the most salient information for speaker identification. Previous literature has suggested that speaking fundamental frequency, long-term spectra, vowel formant frequencies, and speech tempo can provide speaker-specific information. However, investigations focused on automatic speaker identification have provided less than satisfactory results. These findings could be related to how each acoustic parameter is measured or, more probably, to the idea that these acoustic parameters interact in specific ways that may be more obvious in the perceptual realm and may vary across speaking situations. To further complicate matters, individuals may speak more than one language or use multiple dialects. Little is known about the effect of code switching on voice production and identification. The purpose of this presentation is to present some of the relevant literature on voice recognition and factors related to misidentification. The role of intraspeaker variability will be discussed with a special emphasis on bilingualism and bidialectalism. Implications for voice production in augmentative and alternative communication devices will be described.

    Once forensic speaker identification (SI) was recognized as an entity, it was predicted that valid computer based identification systems would quickly become a reality. This has not happened and the review to follow will provide some of the reasons why. Notable among them are (1) the sharp underestimation of its complexity and (2) its confounding with speaker verification (SV). Consideration of these (and related) issues will be followed by a brief history about how the need for SI developed and some of the responses to the problem. Since much of the SI development preceded the structuring of appropriate standards, the recommended stop-gap response described here is based on somewhat uncoordinated, but extensive, research. The product of that effort will be reviewed and organized into a platform which supports SI procedures consistent with the forensic model. Also discussed are the standards which have been established, their impact on SI development and its present limitations. How the cited approach interacts both with progress in verification and the developing SI machine-based identification systems also will be considered. Finally, a few suggestions will be made that should assist in upgrading the effectiveness of aural perceptual speaker identification (AP SI).

    The Iowa Department of Natural Resources. Geological Survey Bureau: the University of Iowa Hygienic Laboratory; and the U.S. Geological Survey (USGS) have been working together to address this question. As part of the Iowa Ground-Water Monitoring Program (IGWM). water samples have been collected from selected Iowa municipal wells since 1982. An examination of this data identified two trends: (1) concentrations of atrazine in Iowa's ground water generally were decreasing over time, and (2) concentrations of metolachlor generally were increasing. Continuing ground-water sampling can determine if these trends represent long-term changes in chemical concentrations.

    The present study investigated the effects of sequence complexity, defined in terms of phonemic similarity and phonotoactic probability, on the timing and accuracy of serial ordering for speech production in healthy speakers and speakers with either hypokinetic or ataxic dysarthria. Sequences were comprised of strings of consonant-vowel (CV) syllables with each syllable containing the same vowel, /a/, paired with a different consonant. High complexity sequences contained phonemically similar consonants, and sounds and syllables that had low phonotactic probabilities; low complexity sequences contained phonemically dissimilar consonants and high probability sounds and syllables. Sequence complexity effects were evaluated by analyzing speech error rates and within-syllable vowel and pause durations. This analysis revealed that speech error rates were significantly higher and speech duration measures were significantly longer during production of high complexity sequences than during production of low complexity sequences. Although speakers with dysarthria produced longer overall speech durations than healthy speakers, the effects of sequence complexity on error rates and speech durations were comparable across all groups. These findings indicate that the duration and accuracy of processes for selecting items in a speech sequence is influenced by their phonemic similarity and/or phonotactic probability. Moreover, this robust complexity effect is present even in speakers with damage to subcortical circuits involved in serial control for speech.

  19. Spelling and dialect: comparisons between speakers of African American vernacular English and White speakers.

    One characteristic of African American vernacular English (AAVE) is final obstruent devoicing, where the final consonant of a word like rigid is pronounced more like /t/ than /d/. To determine whether this dialect characteristic influences adults' spelling, African American and White college students spelled words such as rigid and ballot, pronounced by either a speaker of their own dialect or a speaker of the other dialect. African Americans, especially those who often devoiced final /d/, were more likely than Whites to confuse d and t. Both African American and White spellers made more d/t confusions when the words were spoken by an African American experimenter than by a White experimenter. Thus, the different phonological systems of AAVE and White speakers can cause them to make different types of spelling errors. Discussions of AAVE and literacy have focused on its syntax, but its phonology must also be considered.
