    1998-01-01

    Continuous quality improvement (CQI) activities depend on valid and reliable instruments to generate data. An evaluation of internal and external customer satisfaction is one of the pillars of the CQI process. This article describes the development of a valid and reliable instrument for measuring physicians' satisfaction with the orthopedic nursing units at a major medical trauma center. The physician satisfaction survey instrument was found to be internally consistent (alpha = .95). Confirmatory factor analysis revealed that 68% of the variance in physician satisfaction scores (eigenvalue = 8.14) was explained by using a single-factor model.

    2015-04-01

    The development of a self-report instrument to measure antisocial sport behavior, labeled the Antisocial Sport Behavior Survey (ASBS), among large and diverse samples of athletes is reported. Grounded in the social cognitive theory of moral thought and action (Bandura, 1991) and interpersonal theory (Horowitz, 2004), this instrument was developed and tested in accordance with the traditions of construct validity and classical test theory (Gehlback & Brinkworth, 2011). In Phase 1, 272 college-aged competitive sport participants confirmed a theoretical structure of antisocial sport behavior including eight factors (hypercompetitive, intimidating, antagonistic, disrespectful, exploitable, overly accommodating, abetting, and melodramatic). Phase 2 reports on item development and the response structure of the instrument. In Phase 3, evidence of structural validity and external validity for the ASBS was established with 340 college-aged competitive sport participants. The ASBS presents as a promising new instrument to advance understanding of antisocial sport behavior acts committed by competitive athletes.

    The next generation of multi-object spectrographs (MOS) will deliver comprehensive surveys of the Galaxy, Magellanic Clouds and nearby dwarfs. These will provide us with the vast samples, spanning the full extent of the Hertzsprung-Russell diagram, that are needed to explore the chemistry, history and dynamics of their host systems. Further ahead, the Extremely Large Telescopes (ELTs) will have sufficient sensitivity and angular resolution to extend stellar spectroscopy well beyond the Local Group, opening-up studies of the chemical evolution of galaxies across a broad range of galaxy types and environments. In this contribution I briefly reflect on current and future studies of stellar populations, and introduce plans for the MOSAIC instrument for the European ELT.

    1993-02-01

    Argonne National Laboratory (ANL) is reviewing the survey research studies completed by Mountain West Research (1987-1989) for the state of Nevada`s Nuclear Waste Project Office. In this research, 14 survey instruments were used to seek data on whether perceptions of risk could be associated with the possible siting of a high-level radioactive waste repository in Nevada and could be a dominant source of potential, significant, adverse economic impacts. This report presents results from phase 1 of the review, in which ANL contracted with the National Opinion Research Center (NORC) at the University of Chicago to evaluate the technical merits of the nine survey instruments that ANL had been able to acquire. The scope of NORC`s work was limited to rating the questions and stating their strengths and weaknesses. NORC concluded that the surveys could provide valuable data about risk perceptions and potential behavioral responses. NORC identified a few minor problems with a number of questions and the calculated response rates but claimed these problems would probably not have any major biasing effect. The NORC evaluation would have been more complete if the terms used in the questionnaires had been defined, all survey instruments had been acquired, and all data had been made available to the public.

    In a 2008 survey of the 73 emergency and critical care centers around the nation that were equipped with the drug and chemical analytical instrument provided by the Ministry of Welfare (currently the Ministry of Health, Labour, and Welfare) in 1998, 36 of those facilities were using the analytical instruments. Of these 36 facilities, a follow-up survey of the 17 facilities that recorded 50 or analyses per year. Responses were gained from 16 of the facilities and we learned that of those, 14 facilities (87.5%) were conducting analyses using the instrument. There was a positive mutual correlation between the annual number of cases of the 14 facilities conducting analyses with the instrument and the number of work hours. Depending on the instrument in use, average analytical instrument parts and maintenance expenses were roughly three million yen and consumables required a maximum three million yen for analysis of 51-200 cases per year. From this, we calculate that such expenses can be covered under the allowed budget for advanced emergency and critical care centers of 5,000 NHI points (1 point = 10 yen). We found there were few facilities using the instrument for all 15 of the toxic substances recommended for testing by the Japanese Society for Clinical Toxicology. There tended to be no use of the analytical instrument for compounds with no toxicology cases. However, flexible responses were noted at each facility in relation to frequently analyzed compounds. It is thought that a reevaluation of compounds subject to analysis is required.

    1985-01-01

    An inertial guidance system for aerial surveying has been developed under contract to the U.S. Geological Survey. This prototype system, known as the aerial profiling of terrain (APT) system, is designed to determine continuously the positions of points along an aircraft flight path, or the underlying terrain profile, to an accuracy of + or - 0.5 ft (15 cm) vertically and + or - 2 ft (61 cm) horizontally. The system 's objective thus is to accomplish, from a fixed-wing aircraft, what would traditionally be accomplished from ground-based topographic surveys combined with aerial photography and photogrammetry. The two-part strategy for measuring the terrain profile entails: (1) use of an inertial navigator for continuous determination of the three-coordinate position of the aircraft, and (2) use of an eye-safe pulsed laser profiler for continuous measurement of the vertical distance from aircraft to land surface, so that the desired terrain profile can then be directly computed. The APT system, installed in a DeHavilland Twin Otter aircraft, is typically flown at a speed of 115 mph (105 knots) at an altitude of 2,000 ft (610 m) above the terrain. Performance-evaluation flights have shown that the vertical and horizontal accuracy specifications are met. (USGS)

    To evaluate French residents in Obstetrics and Gynaecology's training in instrumental deliveries in 2015. We conducted a national descriptive survey among 758 residents between December 2014 and January 2015. Respondents were invited by email to specify their University Hospital, their current university term, the number of instrumental deliveries performed by vacuum extractor, forceps or spatulas, and whether they made systematic ultrasound exams before performing the extraction. Response rate was 34.7 % (n=263). There were important differences between regions in terms of type of instruments used. Vacuum extractor was the most commonly used instrument for instrumental deliveries by French residents (56.9 %), more than forceps (25.2 %) and spatulas (17.9 %). At the end of the residency, all the residents had been trained in instrumental deliveries with at least two instruments. The training of difficult techniques as well as their perfect control is required for instrumental deliveries. Yet, we are forced to note that there are substantial differences in the French residents' training in instrumental deliveries depending on their region. So, teaching at least two techniques seems essential as well as improving the training capacities and standardizing practices. A greater systematization of the teaching of the mechanics and obstetric techniques might be a solution to be considered too. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    2010-09-01

    A questionnaire was sent to 73 emergency and critical care centers where high-performance instruments for analyzing drugs and chemicals were provided by the Ministry of Health and Welfare (currently Ministry of Health, Labour and Welfare) in fiscal 1998. 52 centers (71.2%) responded to the questionnaire. Among these, the instruments have been in operation at 36 centers. This means that analytical work has been performed in at least 49.3% (36/73) of facilities with the instruments. A positive correlation was observed between the annual number of patients tested for drugs and chemicals and analytical work hours at the 36 facilities. The results indicated that 150 cases may be tested for drugs and chemicals in a year on the condition that 100 hours a month of analytical work are secured, and 200 or more cases may be tested if 200 hours a month are secured. As for the running costs required for the operation of the instruments, the instrument maintenance and repair cost was estimated at 2 million yen a year, and it was calculated that 100 cases could be handled with a maximum annual supply expense of 1 million yen and 150 cases could be handled with a maximum annual supply expense of 2 million yen. These results suggest that the instrument running cost would be fully covered at nationwide emergency and critical care centers if the additional 5,000 NHI points (1 point = 10 yen) for hospital admission, which is approved for advanced emergency and critical care centers, were applicable to all facilities. Among the 36 facilities, the implementation of analysis varied for each of the 15 toxic substances recommended for analysis by the Japanese Society for Clinical Toxicology. Further research will be necessary to investigate and assess the frequency of analysis requests and combination of simple qualitative and instrumental analyses for each of the 15 substances, in order to evaluate the approach to the 15 substances in analytical work.

    We present predictions for number counts and redshift distributions of galaxies detectable in continuum and in emission lines with the Mid-infrared (MIR) Instrument (SMI) proposed for the Space Infrared Telescope for Cosmology and Astrophysics (SPICA). We have considered 24 MIR fine-structure lines, four Polycyclic Aromatic Hydrocarbon (PAH) bands (at 6.2, 7.7, 8.6 and 11.3$\\mu$m) and two silicate bands (in emission and in absorption) at 9.7$\\mu$m and 18.0$\\mu$m. Six of these lines are primarily associated with Active Galactic Nuclei (AGNs), the others with star formation. A survey with the SMI spectrometers of 1 hour integration per field-of-view (FoV) over an area of $1\\,\\hbox{deg}^2$ will yield $5\\,\\sigma$ detections of $\\simeq 140$ AGN lines and of $\\simeq 5.2\\times10^{4}$ star-forming galaxies, $\\simeq 1.6\\times10^{4}$ of which will be detected in at least two lines.

    Carter, R.J.

    1989-01-01

    A survey oriented towards identifying the human factors issues in regard to the use of advanced instrumentation and controls (I C) in the nuclear industry was conducted. A number of United States (US) and Canadian nuclear vendors and utilities were participants in the survey. Human factors items, subsumed under the categories of computer-generated displays (CGD), controls, organizational support, training, and related topics, were discussed. The survey found the industry to be concerned about the human factors issues related to the implementation of advanced I C. Fifteen potential human factors problems were identified. They include: the need for an advanced I C guideline equivalent to NUREG-0700; a role change in the control room from operator to supervisor; information overload; adequacy of existing training technology for advanced I C; and operator acceptance and trust. 11 refs., 1 tab.

    Parker, Quentin A

    2010-01-01

    In this review we cover the detection, identification and astrophysical importance of planetary nebulae (PN). The legacy of the historic Perek & Kohoutek and Acker et al. catalogues is briefly covered before highlighting the more recent but significant progress in PN discoveries in our Galaxy and the Magellanic Clouds. We place particular emphasis on the major MASH and the IPHAS catalogues, which, over the last decade alone, have essentially doubled Galactic and LMC PN numbers. We then discuss the increasing role and importance that multi-wavelength data is playing in both the detection of candidate PN and the elimination of PN mimics that have seriously biased previous PN compilations. The prospects for future surveys and current efforts and prospects for PN detections in external galaxies are briefly discussed due to their value both as cosmic distance indicators and as kinematical probes of galaxies and dark matter properties.

    A wide field space-based imaging telescope is necessary to fully exploit the technique of observing dark matter via weak gravitational lensing. This first paper in a three part series outlines the survey strategies and relevant instrumental parameters for such a mission. As a concrete example of hardware design, we consider the proposed Supernova/Acceleration Probe (SNAP). Using SNAP engineering models, we quantify the major contributions to this telescope's Point Spread Function (PSF). These PSF contributions are relevant to any similar wide field space telescope. We further show that the PSF of SNAP or a similar telescope will be smaller than current ground-based PSFs, and more isotropic and stable over time than the PSF of the Hubble Space Telescope. We outline survey strategies for two different regimes - a ''wide'' 300 square degree survey and a ''deep'' 15 square degree survey that will accomplish various weak lensing goals including statistical studies and dark matter mapping.

  7. Lateral Violence in Nursing Survey: Instrument Development and Validation

    2017-07-01

    Full Text Available An examination of the psychometric properties of the Lateral Violence in Nursing Survey (LVNS, an instrument previously developed to measure the perceived incidence and severity of lateral violence (LV in the nursing workplace, was carried out. Conceptual clustering and principal components analysis were used with survey responses from 663 registered nurses and ancillary nursing staff in a southeastern tertiary care medical center. Where appropriate, Cronbach’s alpha (α evaluated internal consistency. The prevalence/severity of lateral violence items constitute two distinct subscales (LV by self and others with Cronbach’s alpha of 0.74 and 0.86, respectively. The items asking about potential causes of LV are unidimensional and internally consistent (alpha = 0.77 but there is no conceptually coherent theme underlying the various causes. Respondents rating a potential LV cause as “major” scored higher on both prevalence/severity subscales than those rating it a “minor” cause or not a cause. Subsets of items on the LVNS are internally reliable, supporting construct validity. Revisions of the original LVNS instrument will improve its use in future work.

  8. Archeops: an instrument for present and future cosmology

    CERN Document Server

    Tristram, M

    2003-01-01

    Archeops is a balloon-borne instrument dedicated to measure the cosmic microwave background (CMB) temperature anisotropies. It has, in the millimetre domain (from 143 to 545 GHz), a high angular resolution (about 10 arcminutes) in order to constrain high l multipoles, as well as a large sky coverage fraction (30%) in order to minimize the cosmic variance. It has linked, before WMAP, Cobe large angular scales to the first acoustic peak region. From its results, inflation motivated cosmologies are reinforced with a flat Universe (Omega_tot=1 within 3%). The dark energy density and the baryonic density are in very good agreement with other independent estimations based on supernovae measurements and big bang nucleosynthesis. Important results on galactic dust emission polarization and their implications for Planck are also addressed.

    New water-level sensing and recording instrumentation is being used by the U.S. Geological Survey for monitoring water levels, stream velocities, and water-quality characteristics. Several of these instruments are briefly described. The Basic Data Recorder (BDR) is an electronic data logger, that interfaces to sensor systems through a serial-digital interface standard (SDI-12), which was proposed by the data-logger industry; the Incremental Shaft Encoder is an intelligent water-level sensor, which interfaces to the BDR through the SDI-12; the Pressure Sensor is an intelligent, nonsubmersible pressure sensor, which interfaces to the BDR through the SDI-12 and monitors water levels from 0 to 50 feet; the Ultrasonic Velocity Meter is an intelligent, water-velocity sensor, which interfaces to the BDR through the SDI-12 and measures the velocity across a stream up to 500 feet in width; the Collapsible Hand Sampler can be collapsed for insertion through holes in the ice and opened under the ice to collect a water sample; the Lighweight Ice Auger, weighing only 32 pounds, can auger 6- and 8-inch holes through approximately 3.5 feet of ice; and the Ice Chisel has a specially hardened steel blade and 6-foot long, hickory D-handle.

    The SAMI Galaxy Survey will observe 3400 galaxies with the Sydney-AAO Multi-object Integral-field spectrograph (SAMI) on the Anglo-Australian Telescope (AAT) in a 3-year survey which began in 2013. We present the throughput of the SAMI system, the science basis and specifications for the target selection, the survey observation plan and the combined properties of the selected galaxies. The survey includes four volume limited galaxy samples based on cuts in a proxy for stellar mass, along with low-stellar mass dwarf galaxies all selected from the Galaxy And Mass Assembly (GAMA) survey. The GAMA regions were selected because of the vast array of ancillary data available, including ultraviolet through to radio bands. These fields are on the celestial equator at 9, 12, and 14.5 hours, and cover a total of 144 square degrees (in GAMA-I). Higher density environments are also included with the addition of eight clusters. The clusters have spectroscopy from 2dFGRS and SDSS and photometry in regions covered by the Slo...

This instrument is being designed and assembled by a team of scientists and engineers at New Mexico Tech (NMT), the Magdalena Ridge Observatory (MRO) and NASA's Jet Propulsion Lab (JPL), and is scheduled for deployment in late 2010 at the MRO 2.4m telescope. NESSI's unique design is driven by recent space and ground-based NIR spectroscopy of exoplanet atmospheres by members of our team. Optimization of the instrument to achieve 0.01% relative accuracies in spectra of exoplanetary molecular constituents requires careful attention to certain design features and a new technical approach. We present an overview of NESSI's design, including the four major subassemblies: 1) a field derotator, 2) a reimaging module, 3) an optical guiding module, and 4) a multi-object spectrograph subassembly. We also present an overview of our science program specifically designed to build the community of exoplanet researchers and students in NM. The financial support of our team and NESSI itself have been made possible by a NM NASA EPSCoR grant, matching funds from the NMT administration, and internal support for the NESSI hardware from Dr. Van Romero, NMT's Research Vice-President.

    This paper is a report of a study to explore Australian parents' knowledge, beliefs, practices and information sources about fever management and develop a scale to measure parents' fever management practices. Parental fever phobia and overuse of antipyretics to reduce fever continue. No scales to measure parents' fever management practices are available. A community-based, postal survey was carried out in 2005 with 401 Australian parents of well children aged 6 months-5 years. Respondents were recruited through advertising (48.4%), face-to-face (26.4%) and snowball (24.4%) methods. A 33-item instrument was developed; construct and content validity were determined by an expert panel and item reliability by test-retest. Moderate fever (40.0 +/- 1.0 degrees C) was reported to be harmful (88%), causing febrile convulsions (77.7%). Usual practices targeted temperature reduction, antipyretic administration (87.8%), temperature monitoring (52.5%). Fewer evidence-based practices, such as encouraging fluids (49.0%) and light clothing (43.8%), were reported. Positive changes over time (36.4%) included less concern and delayed or reduced antipyretic use. Negative practice changes (22.7%) included greater concern and increased antipyretic use. Medical advice was sought for illness symptoms (48.7%) and high (37.4%) or persistent (41.5%) fevers. Fever management was learnt from doctors, family and friends and working experience, while receiving conflicting information (41.9%) increased concerns and created uncertainty about best practice. Parents need consistent evidence-based information about childhood fever management. The Parental Fever Management Scale requires further testing with different populations and in different cultures and healthcare systems to evaluate its usefulness in nursing practice and research.

    Teamwork in health care settings is widely recognized as an important factor in providing high-quality patient care. However, the behaviors that comprise effective teamwork, the organizational factors that support teamwork, and the relationship between teamwork and patient outcomes remain empirical questions in need of rigorous study. To identify and review survey instruments used to assess dimensions of teamwork so as to facilitate high-quality research on this topic. We conducted a systematic review of articles published before September 2012 to identify survey instruments used to measure teamwork and to assess their conceptual content, psychometric validity, and relationships to outcomes of interest. We searched the ISI Web of Knowledge database, and identified relevant articles using the search terms team, teamwork, or collaboration in combination with survey, scale, measure, or questionnaire. We found 39 surveys that measured teamwork. Surveys assessed different dimensions of teamwork. The most commonly assessed dimensions were communication, coordination, and respect. Of the 39 surveys, 10 met all of the criteria for psychometric validity, and 14 showed significant relationships to nonself-report outcomes. Evidence of psychometric validity is lacking for many teamwork survey instruments. However, several psychometrically valid instruments are available. Researchers aiming to advance research on teamwork in health care should consider using or adapting one of these instruments before creating a new one. Because instruments vary considerably in the behavioral processes and emergent states of teamwork that they capture, researchers must carefully evaluate the conceptual consistency between instrument, research question, and context.

    The Dark Energy Spectroscopic Instrument (DESI) will enable an ambitious redshift survey to probe dark energy by the baryon acoustic oscillation and redshift-space distortion methods. The same data set will serve numerous other goals in cosmology and astrophysics. Using a new 5000-fiber instrument and 8 square degree field of view at the Mayall telescope, the DESI survey plans to cover 14,000 square degrees and about 25 million high-redshift objects. The targets include 4M luminous red galaxies (redshift 0.4-1.0), 18M emission line galaxies (redshift 0.6-1.6), and 2.4M quasars, including 0.7M Lyman-alpha forest sight lines. With this, DESI can map the expansion history of the Universe to redshift 3, achieving unprecedented performance from the baryon acoustic oscillation method. We will describe the present state of the survey design and the cosmological forecasts for dark energy, inflation, and neutrino physics. We also give an update on the DESI Science Collaboration.

    To develop a theoretically informed and empirically validated survey instrument for assessing prescribers' perception of computerized drug-drug interaction (DDI) alerts. The survey is grounded in the unified theory of acceptance and use of technology and an adapted accident causation model. Development of the instrument was also informed by a review of the extant literature on prescribers' attitude toward computerized medication safety alerts and common prescriber-provided reasons for overriding. To refine and validate the survey, we conducted a two-stage empirical validation study consisting of a pretest with a panel of domain experts followed by a field test among all eligible prescribers at our institution. The resulting survey instrument contains 28 questionnaire items assessing six theoretical dimensions: performance expectancy, effort expectancy, social influence, facilitating conditions, perceived fatigue, and perceived use behavior. Satisfactory results were obtained from the field validation; however, a few potential issues were also identified. We analyzed these issues accordingly and the results led to the final survey instrument as well as usage recommendations. High override rates of computerized medication safety alerts have been a prevalent problem. They are usually caused by, or manifested in, issues of poor end user acceptance. However, standardized research tools for assessing and understanding end users' perception are currently lacking, which inhibits knowledge accumulation and consequently forgoes improvement opportunities. The survey instrument presented in this paper may help fill this methodological gap. We developed and empirically validated a survey instrument that may be useful for future research on DDI alerts and other types of computerized medication safety alerts more generally.

    2010-06-01

    This article places the famous images of Johannes Hevelius's instruments in his Machina Coelestis (1673) in the context of Hevelius's contested cometary observations and his debate with Hooke over telescopic sights. Seen thus, the images promote a crafted vision of Hevelius's astronomical practice and skills, constituting a careful self-presentation to his distant professional network and a claim as to which instrumental techniques guarantee accurate observations. Reviewing the reception of the images, the article explores how visual rhetoric may be invoked and challenged in the context of controversy, and suggests renewed analytical attention to the role of laboratory imagery in instrumental cultures in the history of science.

    Both personal digital assistants (PDAs) and tablet computers have emerged to facilitate data collection at the point of care. However, little research has been reported comparing these mobile computing devices in specific care settings. In this study we present an approach for comparing functionally identical applications on a Palm operating system-based PDA and a Windows-based tablet computer for point-of-care documentation of clinical observations by eye care professionals when caring for patients with diabetes. Eye-care professionals compared the devices through focus group sessions and through validated usability surveys. This poster describes the development and use of the survey instrument used for comparing mobile computing devices. PMID:16779327

    Full Text Available Abstract Background The primary objective was to systematically review the medical literature for instruments validated for use in epidemiological and clinical research on waterpipe smoking. Methods We searched the following databases: MEDLINE, EMBASE, and ISI the Web of Science. We selected studies using a two-stage duplicate and independent screening process. We included papers reporting on the development and/or validation of survey instruments to measure waterpipe tobacco consumption or related concepts. Two reviewers used a standardized and pilot tested data abstraction form to collect data from each eligible study using a duplicate and independent screening process. We also determined the percentage of observational studies assessing the health effects of waterpipe tobacco smoking and the percentage of studies of prevalence of waterpipe tobacco smoking that have used validated survey instruments. Results We identified a total of five survey instruments. One instrument was designed to measure knowledge, attitudes, and waterpipe use among pregnant women and was shown to have internal consistency and content validity. Three instruments were designed to measure waterpipe tobacco consumption, two of which were reported to have face validity. The fifth instrument was designed to measure waterpipe dependence and was rigorously developed and validated. One of the studies of prevalence and none of the studies of health effects of waterpipe smoking used validated instruments. Conclusions A number of instruments for measuring the use of and dependence on waterpipe smoking exist. Future research should study content validity and cross cultural adaptation of these instruments.

    A study was conducted of instrumentation used to determine metals in water. Several of the techniques most commonly used for analysis and routine determinations of metals in water are shown in Table 1. They are atomic absorption spectroscopy, both flame and flameless, atomic emission spectroscopy using conventional flame sources and inductively-coupled plasma sources, and ultraviolet-visible absorption techniques. Other less frequently employed methods are x-ray fluorescence analysis using both photon and charged particle excitation with energy-dispersive and wavelength-dispersive spectral analysis. Also electrochemical techniques and activation analysis are studied.

    The Multi-sensor Airborne Radiation Survey (MARS) project has developed a new single cryostat detector array design for high purity germanium (HPGe) gama ray spectrometers that achieves the high detection efficiency required for stand-off detection and actionable characterization of radiological threats. This approach, we found, is necessary since a high efficiency HPGe detector can only be built as an array due to limitations in growing large germanium crystals. Moreover, the system is ruggedized and shock mounted for use in a variety of field applications, including airborne and maritime operations.

    2015-01-01

    The Galactic All-Sky Survey is a survey of Galactic atomic hydrogen emission in the southern sky observed with the Parkes 64-m Radio Telescope. The first data release (GASS I) concerned survey goals and observing techniques, the second release (GASS II) focused on stray radiation and instrumental corrections. We seek to remove the remaining instrumental effects and present a third data release. We use the HEALPix tessellation concept to grid the data on the sphere. Individual telescope records are compared with averages on the nearest grid position for significant deviations. All averages are also decomposed into Gaussian components with the aim of segregating unacceptable solutions. Improved priors are used for an iterative baseline fitting and cleaning. In the last step we generate 3-D FITS data cubes and examine them for remaining problems. We have removed weak, but systematic baseline offsets with an improved baseline fitting algorithm. We have unraveled correlator failures that cause time dependent oscil...

    Questionnaires for the assessment of knowledge and self-perception can be useful to diagnose what a dentist knows about management and administration. The aim of the present study was to create and validate the Dental Management Survey Brazil (DMS-BR) scale, based on meetings with experts in the field. After having elaborated the first version, 10 audits were performed in dental offices in order to produce the final version, which included nine dimensions: location, patient, finance, marketing, competition, quality, staff, career, and productivity. The accuracy of the instrument was measured by intrarater and interrater reliability. In the validation phase, 247 Brazilian dentists answered a web-based questionnaire. The data were processed using Stata 13.0 and the significance level was set at 95%. The instrument had intrarater and interrater reliability (ICC-0.93 and 0.94). The overall average of respondents for the DMS-BR scale was 3.77 (SD = 0.45). Skewness and kurtosis were below absolute values 3 and 7, respectively. Internal validity measured by Cronbach's alpha was 0.925 and the correlation of each dimension with the final result of the DMS-BR ranged between 0.606 and 0.810. Correlation with the job satisfaction scale was 0.661. The SEM data ranged between 0.80 and 0.56. The questionnaire presented satisfactory indicators of dentists' self-perception about management and administration activities.

    Economic theory suggests that willingness to pay for two goods independently offered should remain unchanged when the survey instrument changes slightly. Four survey treatments consisting of comprehensive good and a subset of that good were used. The surveys alternated in the question ordering and in the embedded good which accompanied the comprehensive good. We tested for sequencing and instrument context effects using both a combined and split sample designs. In the combined sample case we found some evidence to sequencing effects in the data containing the first subset good. Likelihood ratio tests indicated that sequencing did not effect scale or location of parameters. In the test for instrument context effects, evidence was found indicating context does effect willingness to pay estimates.

    Full Text Available This paper surveys the workflow analysis in the view of business process for all organizations. The business can be defined as an organization that provides goods and services to others, who want or need them. The concept of managing business processes is referred to as Business Process Management (BPM. A workflow is the automation of a business process, in whole or part, during which documents, information or tasks are passed from one participant to another for action, according to a set of procedural rules. The process mining aims at extracting useful and meaningful information from event logs, which is a set of real executions of business process at any organizations. This paper briefly reviews the state-or-the-art of business processes developed so far and the techniques adopted. Also presents, the survey of workflow analysis in the view of business process can be broadly classified into four major categories, they are Business Process Modeling, Ontology based Business Process Management, Workflow based Business Process Controlling and Business Process Mining.

    SCK-CEN's research and development programme on instrumentation involves the assessment and the development of sensitive measurement systems used within a radiation environment. Particular emphasis is on the assessment of optical fibre components and their adaptability to radiation environments. The evaluation of ageing processes of instrumentation in fission plants, the development of specific data evaluation strategies to compensate for ageing induced degradation of sensors and cable performance form part of these activities. In 2000, particular emphasis was on in-core reactor instrumentation applied to fusion, accelerator driven and water-cooled fission reactors. This involved the development of high performance instrumentation for irradiation experiments in the BR2 reactor in support of new instrumentation needs for MYRRHA, and for diagnostic systems for the ITER reactor.

    The Gaia SpectroPhotometric Standard Stars (SPSS) survey started in 2006, it was awarded almost 450 observing nights, and accumulated almost 100,000 raw data frames, with both photometric and spectroscopic observations. Such large observational effort requires careful, homogeneous, and automated data reduction and quality control procedures. In this paper, we quantitatively evaluate instrumental effects that might have a significant (i.e.,$\\geq$1%) impact on the Gaia SPSS flux calibration. The measurements involve six different instruments, monitored over the eight years of observations dedicated to the Gaia flux standards campaigns: DOLORES@TNG in La Palma, EFOSC2@NTT and ROSS@REM in La Silla, CAFOS@2.2m in Calar Alto, BFOSC@Cassini in Loiano, and LaRuca@1.5m in San Pedro Martir. We examine and quantitatively evaluate the following effects: CCD linearity and shutter times, calibration frames stability, lamp flexures, second order contamination, light polarization, and fringing. We present methods to correct ...

  19. Measuring social exclusion in routine public health surveys: construction of a multidimensional instrument.

    Directory of Open Access Journals (Sweden)

    Addi P L van Bergen

    Full Text Available INTRODUCTION: Social exclusion is considered a major factor in the causation and maintenance of health inequalities, but its measurement in health research is still in its infancy. In the Netherlands the Institute for Social Research (SCP developed an instrument to measure the multidimensional concept of social exclusion in social and economic policy research. Here, we present a method to construct a similar measure of social exclusion using available data from public health surveys. METHODS: Analyses were performed on data from the health questionnaires that were completed by 20,877 adults in the four largest cities in the Netherlands. From each of the four questionnaires we selected the items that corresponded to those of the SCP-instrument. These were entered into a nonlinear canonical correlation analysis. The measurement properties of the resulting indices and dimension scales were assessed and compared to the SCP-instrument. RESULTS: The internal consistency of the indices and most of the dimension scales were adequate and the internal structure of the indices was as expected. Both generalisabiliy and construct validity were good: in all datasets strong associations were found between the index and a number of known risk factors of social exclusion. A limitation of content validity was that the dimension "lack of normative integration" could not be measured, because no relevant items were available. CONCLUSIONS: Our findings indicate that a measure for social exclusion can be constructed with available health questionnaires. This provides opportunities for application in public health surveillance systems in the Netherlands and elsewhere in the world.

    Full Text Available One of the principal issues in any university community is the lack of communication between community categories – leadership, administration, teaching staff and students. Sometimes is important to know in a short time the opinion of one particular group, without investing a lot of resources and without being extremely formal. The aim of this study was to test if an open-source platform – Moodle – can be used for quick surveys inside the Faculty of Medicine, UMF “Iuliu Hatieganu” Cluj-Napoca community. For this, on existing Moodle platform was installed one specific survey instrument – a questionnaire module and a survey containing a real life issue to the students of Faculty of Medicine was launched. The researchers have focused on how the specific problems of a survey - preparing of the survey, the survey process and the analysis of the results can be handle in Moodle. The pilot survey was a success; the conclusion of the study was that Moodle can be used as on-line survey instrument for that community.

    Measurement and our understanding of safety culture are still evolving. The objectives of this study were to assess variation in safety and teamwork climate and in the neonatal intensive care unit (NICU) setting, and compare measurement of safety culture scales using two different instruments (Safety Attitudes Questionnaire (SAQ) and Hospital Survey on Patient Safety Culture (HSOPSC)). Cross-sectional survey study of a voluntary sample of 2073 (response rate 62.9%) health professionals in 44 NICUs. To compare survey instruments, we used Spearman's rank correlation coefficients. We also compared similar scales and items across the instruments using t tests and changes in quartile-level performance. We found significant variation across NICUs in safety and teamwork climate scales of SAQ and HSOPSC (pteamwork scales (teamwork climate and teamwork within units) of the two instruments correlated strongly (safety r=0.72, pteamwork r=0.67, p<0.001). However, the means and per cent agreements for all scale scores and even seemingly similar item scores were significantly different. In addition, comparisons of scale score quartiles between the two instruments revealed that half of the NICUs fell into different quartiles when translating between the instruments. Large variation and opportunities for improvement in patient safety culture exist across NICUs. Important systematic differences exist between SAQ and HSOPSC such that these instruments should not be used interchangeably. Published by the BMJ Publishing Group Limited.

    The Tropospheric Monitoring Instrument (TROPOMI) on-board the Sentinel-5 Precursor satellite is an Earth-observing spectrometer with bands in the ultraviolet, visible, near infrared and short-wave infrared (SWIR). It provides daily global coverage of atmospheric trace gases relevant for tropospheric air quality and climate research. Three new techniques will be presented that are unique for the TROPOMI-SWIR spectrometer. The retrieval of methane and CO columns from the data of the SWIR band requires for each detector pixel an accurate instrument spectral response function (ISRF), i.e. the normalized signal as a function of wavelength. A new determination method for Earth-observing instruments has been used in the on-ground calibration, based on measurements with a SWIR optical parametric oscillator (OPO) that was scanned over the whole TROPOMI-SWIR spectral range. The calibration algorithm derives the ISRF without needing the absolute wavelength during the measurement. The same OPO has also been used to determine the two-dimensional stray-light distribution for each SWIR pixel with a dynamic range of 7 orders. This was achieved by combining measurements at several exposure times and taking saturation into account. The correction algorithm and data are designed to remove the mean stray-light distribution and a reflection that moves relative to the direct image, within the strict constraints of the available time for the L01b processing. A third new technique is an alternative calibration of the SWIR absolute radiance and irradiance using a black body at the temperature of melting silver. Unlike a standard FEL lamp, this source does not have to be calibrated itself, because the temperature is very stable and well known. Measurement methods, data analyses, correction algorithms and limitations of the new techniques will be presented.

  8. Understanding Teachers' Conceptions of Classroom Inquiry With a Teaching Scenario Survey Instrument

    2008-08-01

    A survey instrument using everyday teaching scenarios was developed to measure teacher conceptions of inquiry. Validity of the instrument was established by comparing responses for a group of secondary teachers to narrative writing and group discussion. Participating teachers used only three of the five essential features of inquiry detailed in the standards documents (NRC 2000) when expressing their ideas of classroom inquiry. The features of ‘evaluating explanations in connection with scientific knowledge’ and ‘communicating explanations’ were rarely mentioned. These missing components indicate a gap between the teachers’ conceptions of inquiry and the ideals of the reform movement.

  9. The Mathematics Attitudes and Perceptions Survey: an instrument to assess expert-like views and dispositions among undergraduate mathematics students

    2016-08-01

    One goal of an undergraduate education in mathematics is to help students develop a productive disposition towards mathematics. A way of conceiving of this is as helping mathematical novices transition to more expert-like perceptions of mathematics. This conceptualization creates a need for a way to characterize students' perceptions of mathematics in authentic educational settings. This article presents a survey, the Mathematics Attitudes and Perceptions Survey (MAPS), designed to address this need. We present the development of the MAPS instrument and its validation on a large (N = 3411) set of student data. Results from various MAPS implementations corroborate results from analogous instruments in other STEM disciplines. We present these results and highlight some in particular: MAPS scores correlate with course grades; students tend to move away from expert-like orientations over a semester or year of taking a mathematics course; and interactive-engagement type lectures have less of a negative impact, but no positive impact, on students' overall orientations than traditional lecturing. We include the MAPS instrument in this article and suggest ways in which it may deepen our understanding of undergraduate mathematics education.

    Full Text Available A review of the past and present instrumentation at Ebre Observatory seismological station (EBR is presented in this work. In order to assess the quality of EBR from the point of view of modern seismic instrumentation site requirements, the noise conditions at EBR are also investigated by means of velocity power spectral density analysis in the frequency band 0.01< f <15 Hz by exploiting the three component broadband and digital data processing current capability. A correlation between noise levels and meteorological conditions at the site is observed, using the data of a complete meteorological station located a few tens of meters from the seismic cave. Results show that for long periods ( f < 0.04 Hz and wind speeds ranging from 0 to 15.5 m/s, seismic noise levels may vary up to 45 dB for the horizontal components. These variations are related to tilts due to wind-generated pressure fl uctuations. Secondly, the seasonal variation of noise levels at the frequency band 0.04 < f < 0.3 Hz is characterized, obtaining that the amplitude of the seasonal variation is higher for secondary (up to 52 dB than for primary (up to 44 dB microseisms. On the other hand, a seasonal variation of the frequency of the three-component main noise peak is also suggested in this site and its variation is opposite to the velocity power spectral density amplitude evolution. Finally, a correlation between wind speed and seismic background noise is also observed at high frequencies.

    2012-01-01

    Over the last decade Galactic planetary nebula discoveries have entered a golden age due to the emergence of high sensitivity, high resolution narrow-band surveys of the Galactic plane. These have been coupled with access to complimentary, deep, multi-wavelength surveys across near-IR, mid-IR and radio regimes in particular from both ground-based and space-based telescopes. These have provided powerful diagnostic and discovery capabilities. In this review these advances are put in the context of what has gone before, what we are uncovering now and through the window of opportunity that awaits in the future. The astrophysical potential of this brief but key phase of late stage stellar evolution is finally being realised.

    Most measures of cognitive function used in large-scale surveys of older adults have limited ability to detect subtle differences across cognitive domains, and standard clinical instruments are impractical to administer in general surveys. The Montreal Cognitive Assessment (MoCA) can address this need, but has limitations in a survey context. Therefore, we developed a survey adaptation of the MoCA, called the MoCA-SA, and describe its psychometric properties in a large national survey. Using a pretest sample of older adults (n=120), we reduced MoCA administration time by 26%, developed a model to accurately estimate full MoCA scores from the MoCA-SA, and tested the model in an independent clinical sample (n=93). The validated 18-item MoCA-SA was then administered to community-dwelling adults aged 62 to 91 as part of the National Social life Health and Aging Project Wave 2 sample (n=3196). In National Social life Health and Aging Project Wave 2, the MoCA-SA had good internal reliability (Cronbach α=0.76). Using item-response models, survey-adapted items captured a broad range of cognitive abilities and functioned similarly across sex, education, and ethnic groups. Results demonstrate that the MoCA-SA can be administered reliably in a survey setting while preserving sensitivity to a broad range of cognitive abilities and similar performance across demographic subgroups.

    The Mediterranean diet (MD) can reduce chronic disease risk and is a recommended diet for prevention and management of diabetes. Adherence to the MD in the southeast United States where obesity and diabetes are highly prevalent is unknown. The purpose of the present study was to: 1) construct a survey instrument relevant to the general population integrating both MD related nutrition knowledge and adherence questions from previously validated instruments, and 2) assess MD related nutrition knowledge and adherence in a sample population in the southest United States. Adherance was assessed using the validated short MD Adherence Screener (MEDAS). A MD nutrition knowledge (MDNK) questionnaire was developed from previously validated general nutrition knowledge questionnaires and was validated using 127 university students enrolled in three courses with varying levels of nutrition education. Cronbach's α for internal validity of MDNK was acceptable for a short questionnaire (0.653). Test-retest reliability was established (r = 0.853). Field validation of the three-part survey instrument (MEDAS, MDNK and demographic questions) was subsequently performed in 230 adults shopping at supermarkets and farmers markets in eastern Alabama. Total MDNK and MEDAS scores were significantly higher in students with formal nutrition education and in patrons of farmers markets. Greater MD adherence, assessed by dividing MEDAS scores into thirds, was found with increasing formal nutrition education in university students (p = 0.002) and in farmers market participants (p < 0.001). There was a weak but significant association between MDNK and MEDAS scores within university students and participants in the field. Together, the MDNK-MEDAS survey instrument is an effective tool for assessing baseline knowledge and adherence and can be used to target nutritional interventions to improve MD adherence for prevention and management of diabetes and other chronic disease.

    1991-01-01

    The U.S. Geological Survey is acquiring a new generation of field computers and communications software to support hydrologic data-collection at field locations. The new computer hardware and software mark the beginning of the Survey's transition from the use of electromechanical devices and paper tapes to electronic microprocessor-based instrumentation. Software is being developed for these microprocessors to facilitate the collection, conversion, and entry of data into the Survey's National Water Information System. The new automated data-collection process features several microprocessor-controlled sensors connected to a serial digital multidrop line operated by an electronic data recorder. Data are acquired from the sensors in response to instructions programmed into the data recorder by the user through small portable lap-top or hand-held computers. The portable computers, called personal field computers, also are used to extract data from the electronic recorders for transport by courier to the office computers. The Survey's alternative to manual or courier retrieval is the use of microprocessor-based remote telemetry stations. Plans have been developed to enhance the Survey's use of the Geostationary Operational Environmental Satellite telemetry by replacing the present network of direct-readout ground stations with less expensive units. Plans also provide for computer software that will support other forms of telemetry such as telephone or land-based radio.

    The Advanced Camera for Surveys (ACS), a third-generation instrument, was installed in the Hubble Space Telescope during Servicing Mission 3B, on March 7, 2002. Its primary purpose was to increase HST imaging discovery efficiency by about a factor of 10, with a combination of detector area and quantum efficiency that surpasses previous instruments. ACS has three independent cameras that have provided wide-field, high resolution, and ultraviolet imaging capabilities respectively, using a broad assortment of filters designed to address a large range of scientific goals. In addition, coronagraphic, polarimetric, and grism capabilities have made the ACS a versatile and powerful instrument. The ACS Instrument Handbook, which is maintained by the ACS Team at STScI, descr ibes the instrument properties, performance, operations, and calibration. It is the basic technical reference manual for the instrument, and should be used with other documents (listed in Table 1.1) for writing Phase I proposals, detailed Phase II programs, and for data analysis. (See Figure 1.1). In May 2009, Servicing Mission 4 (SM4) successfully restored the ACS Wide Field Camera (WFC) to regular service after its failure in January 2007. Unfortunately, the ACS High Resolution Camera (HRC) was not restored to operation during SM4, so it cannot be proposed for new observations. Nevertheless, this handbook retains description of the HRC to support analysis of archived observations. The ACS Solar Blind Channel (SBC) was unaffected by the January 2007 failure of WFC and HRC. The SBC has remained in steady operation, and was not serviced during SM4. It remains available for new observations.

    Full Text Available A 2014 nationwide survey in radish fields investigated the distribution of common viruses and possible emerging viruses. Radish leaves with virus-like symptoms were collected and 108 samples assayed by RT-PCR using specific primers for Radish mosaic virus (RaMV, Cucumber mosaic virus (CMV, and Turnip mosaic virus (TuMV; 47 samples were TuMV positive, and RaMV and CMV were detected in 3 and 2 samples, respectively. No samples showed double infection of TuMV/RaMV, or RaMV/CMV, but two double infections of TuMV/CMV were detected. TuMV isolates were sorted by symptom severity, and three isolates (R007-mild; R041 and R065-severe selected for BLAST and phylogenetic analysis, which indicated that the coat protein (CP of these isolates (R007, R041, and R065 have approx. 98-99% homology to a previously reported TuMV isolate. RaMV CP showed approx. 99% homology to a previously reported isolate, and the CMV CP is identical to a previously reported Korean isolate (GenBank : GU327368. Three isolates of TuMV showing different pathogenicity (degree of symptom severity will be valuable to study determinants of pathogenicity.

    Communication between the patient and the professional carer lies at the heart of all decisions regarding diagnosis and treatment. However, patients and doctors often have divergent views on care needs; 2-COM (for 2-communication) is a simple patient-completed self-report instrument designed in order to facilitate patient-professional carer communication. Aims - To present 2-COM and to examine whether providing patients with an opportunity to identify and discuss their needs would improve communication and induce changes in care. Methods - The 2-COM is a simple list of 20 common problems, or areas of perceived need, that might be experienced by patients with severe mental illness. The list includes problems with housing, relationships, money, lack of activities, psychological distress, sexuality, symptoms and treatment side effects; 2-COM has shown adequate test-retest reliability and is well accepted by patients as a valued aid to communication with their doctor; 134 patients in a clinical diagnosis of schizophrenia or schizoaffective disorder were recruited at seven European centres: Maastricht, Oviedo, Gijon, Hamburg, Copenhagen, Milan and Nice. The assessment took place over 3 out patient clinic visits; at visit 1, the clinician recorded a list of all current interventions, including medication and non-medical treatments, together with demographic information and an assessment of current level of functioning, using the Global Assessment of Functioning scale. Prior to the second visit, patients were randomised to receive either 2-COM or "standard care" - a routine appointment without 2-COM. Immediately after the interview, all patients, whether they had completed 2-COM or not, completed a confidential questionnaire in which they could indicate the perceived quality of communication. Similarly, clinicians completed a repeat of the list of all current interventions, together with an assessment of any changes to the treatment plan implemented after the interview

    3d scanning technologies had a significant development and have been widely used in documentation of cultural, architectural and archeological heritages. Modern methods of three-dimensional acquiring and modeling allow to represent an object through a digital model that combines visual potentialities of images (normally used for documentation) to the accuracy of the survey, becoming at the same time support for the visualization that for metric evaluation of any artefact that have an historical or artistic interest, opening up new possibilities for cultural heritage's fruition, cataloging and study. Despite this development, because of the small catchment area and the 3D laser scanner's sophisticated technologies, the cost of these instruments is very high and beyond the reach of most operators in the field of cultural heritages. This is the reason why they have appeared low-cost technologies or even free, allowing anyone to approach the issues of acquisition and 3D modeling, providing tools that allow to create three-dimensional models in a simple and economical way. The research, conducted by the Laboratory of Photogrammetry of the University IUAV of Venice, of which we present here some results, is intended to figure out whether, with Arc3D, it is possible to obtain results that can be somehow comparable, in therms of overall quality, to those of the laser scanner, and/or whether it is possible to integrate them. They were carried out a series of tests on certain types of objects, models made with Arc3D, from raster images, were compared with those obtained using the point clouds from laser scanner. We have also analyzed the conditions for an optimal use of Arc3D: environmental conditions (lighting), acquisition tools (digital cameras) and type and size of objects.

  1. GASS: The Parkes Galactic All-Sky Survey. Update: improved correction for instrumental effects and new data release

    Kalberla, P. M. W.; Haud, U.

    2015-06-01

    Context. The Galactic All-Sky Survey (GASS) is a survey of Galactic atomic hydrogen (H i) emission in the southern sky observed with the Parkes 64-m Radio Telescope. The first data release (GASS I) concerned survey goals and observing techniques, the second release (GASS II) focused on stray radiation and instrumental corrections. Aims: We seek to remove the remaining instrumental effects and present a third data release. Methods: We use the HEALPix tessellation concept to grid the data on the sphere. Individual telescope records are compared with averages on the nearest grid position for significant deviations. All averages are also decomposed into Gaussian components with the aim of segregating unacceptable solutions. Improved priors are used for an iterative baseline fitting and cleaning. In the last step we generate 3D FITS data cubes and examine them for remaining problems. Results: We have removed weak, but systematic baseline offsets with an improved baseline fitting algorithm. We have unraveled correlator failures that cause time dependent oscillations; errors cause stripes in the scanning direction. The remaining problems from radio frequency interference (RFI) are spotted. Classifying the severeness of instrumental errors for each individual telescope record (dump) allows us to exclude bad data from averages. We derive parameters that allow us to discard dumps without compromising the noise of the resulting data products too much. All steps are reiterated several times: in each case, we check the Gaussian parameters for remaining problems and inspect 3D FITS data cubes visually. We find that in total ~1.5% of the telescope dumps need to be discarded in addition to ~0.5% of the spectral channels that were excluded in GASS II. Conclusions: The new data release (GASS III) facilitates data products with improved quality. A new web interface, compatible with the previous version, is available for download of GASS III FITS cubes and spectra.

    A new polarimeter based on the wedged double Wollaston concept has been built at the Torino Observatory and installed on a 1-m telescope at the Calern observing station of the Observatoire de la Côte d'Azur, France. Its main purpose is to carry out a polarimetric survey of minor Solar system objects, which is called the Calern Asteroid Polarimetric Survey. In this paper, we describe the new Torino polarimeter and the results of preliminary scientific validation tests. A number of standard stars with known polarization states, as well as a number of asteroids for which the polarimetric properties are known, have been observed in order to assess the instrument's accuracy. The instrumental polarization has been found to be stable within a few 10-4 units. A total of 124 new polarimetric observation of 78 asteroids are presented. In the case of asteroids already observed in the past, the new data are in agreement with available phase-polarization curves with error bars smaller than most previously published data. We also present data for 21 asteroids that have never been observed before in polarimetry.

    The possibility of the application of Surveying Biochemistry Light Instrument (SBLI) in the reaction system of starch with Mn3+was studied. The results showed: neither starch nor initiator(Mn3+) could produce light because no factor that could produce light existed in them. But starch could produce light when it was acted by Mn3 + and the intensity of light depended on the kind and concentration of starch, the amount of Mn3 +, the temperature and pH of the reaction system. In addition, the intensity of light decreased with the reaction time because of the gradual disappearance of starch free radicals.

  4. Understanding nature's particle accelerators using high energy gamma-ray survey instruments

    Science.gov (United States)

    Abeysekara, Anushka Udara

    Nature's particle accelerators, such as Pulsars, Pulsar Wind Nebulae, Active Galactic Nuclei and Supernova Remnants accelerate charged particles to very high energies that then produce high energy photons. The particle acceleration mechanisms and the high energy photon emission mechanisms are poorly understood phenomena. These mechanisms can be understood either by studying individual sources in detail or, alternatively, using the collective properties of a sample of sources. Recent development of GeV survey instruments, such as Fermi-LAT, and TeV survey instruments, such as Milagro, provides a large sample of high energy gamma-ray flux measurements from galactic and extra-galactic sources. In this thesis I provide constraints on GeV and TeV radiation mechanisms using the X-ray-TeV correlations and GeV-TeV correlations. My data sample was obtained from three targeted searches for extragalactic sources and two targeted search for galactic sources, using the existing Milagro sky maps. The first extragalactic candidate list consists of Fermi-LAT GeV extragalactic sources, and the second extragalactic candidate list consists of TeVCat extragalactic sources that have been detected by Imaging Atmospheric Cerenkov Telescopes (IACTs). In both extragalactic candidate lists Markarian 421 was the only source detected by Milagro. A comparison between the Markarian 421 time-averaged flux, measured by Milagro, and the flux measurements of transient states, measured by IACTs, is discussed. The third extragalactic candidate list is a list of potential TeV emitting BL Lac candidates that was synthesized using X-ray observations of BL Lac objects and a Synchrotron Self-Compton model. Milagro's sensitivity was not sufficient to detect any of those candidates. However, the 95% confidence flux upper limits of those sources were above the predicted flux. Therefore, these results provide evidence to conclude that the Synchrotron Self-Compton model for BL Lac objects is still a viable

    Reticular dysgenesis (RD) is a rare congenital disorder defined clinically by the combination of severe combined immunodeficiency (SCID), agranulocytosis, and sensorineural deafness. Mutations in the gene encoding adenylate kinase 2 were identified to cause the disorder. Hematopoietic stem cell transplantation (HSCT) is the only option to cure this otherwise fatal disease. Retrospective data on clinical presentation, genetics, and outcome of HSCT were collected from centers in Europe, Asia, and North America for a total of 32 patients born between 1982 and 2011. Age at presentation was <4 weeks in 30 of 32 patients (94%). Grafts originated from mismatched family donors in 17 patients (55%), from matched family donors in 6 patients (19%), and from unrelated marrow or umbilical cord blood donors in 8 patients (26%). Thirteen patients received secondary or tertiary transplants. After transplantation, 21 of 31 patients were reported alive at a mean follow-up of 7.9 years (range: 0.6-23.6 years). All patients who died beyond 6 months after HSCT had persistent or recurrent agranulocytosis due to failure of donor myeloid engraftment. In the absence of conditioning, HSCT was ineffective to overcome agranulocytosis, and inclusion of myeloablative components in the conditioning regimens was required to achieve stable lymphomyeloid engraftment. In comparison with other SCID entities, considerable differences were noted regarding age at presentation, onset, and type of infectious complications, as well as the requirement of conditioning prior to HSCT. Although long-term survival is possible in the presence of mixed chimerism, high-level donor myeloid engraftment should be targeted to avoid posttransplant neutropenia. © 2017 by The American Society of Hematology.

    A system dedicated to the optical transmittance characterization of Fresnel lenses has been developed at NREL, in collaboration with the UPM. The system quantifies the optical efficiency of the lens by generating a performance map. The shape of the focused spot may also be analyzed to understand change in the lens performance. The primary instrument components (lasers and CCD detector) have been characterized to confirm their capability for performing optical transmittance measurements. Measurements performed on SoG and PMMA lenses subject to a variety of indoor conditions (e.g., UV and damp heat) identified differences in the optical efficiency of the evaluated lenses, demonstrating the ability of the Scanning Lens Instrument (SLI) to distinguish between the aged lenses.

    To measure the parameter of job satisfaction among anesthesiologists. Survey instrument. Academic anesthesiology departments in the United States. 320 anesthesiologists who attended the annual meeting of the ASA in 2009 (95% response rate). The anonymous 50-item survey collected information on 26 independent demographic variables and 24 dependent ranked variables of career satisfaction among practicing anesthesiologists. Mean survey scores were calculated for each demographic variable and tested for statistically significant differences by analysis of variance. Questions within each domain that were internally consistent with each other within domains were identified by Cronbach's alpha ≥ 0.7. P-values ≤ 0.05 were considered statistically significant. Cronbach's alpha analysis showed strong internal consistency for 10 dependent outcome questions in the practice factor-related domain (α = 0.72), 6 dependent outcome questions in the peer factor-related domain (α = 0.71), and 8 dependent outcome questions in the personal factor-related domain (α = 0.81). Although age was not a variable, full-time status, early satisfaction within the first 5 years of practice, working with respected peers, and personal choice factors were all significantly associated with anesthesiologist job satisfaction. Improvements in factors related to job satisfaction among anesthesiologists may lead to higher early and current career satisfaction. Copyright © 2013 Elsevier Inc. All rights reserved.

    2016-06-01

    The purpose of this study was to evaluate, through a systematic review, assessment instruments for evidence-based practice (EBP). The specific objectives were to (1) identify survey instruments testing EBP knowledge, skills, attitudes and behaviour; (2) determine the attributes measured by each instrument; (3) evaluate the psychometric properties of the instruments; and (4) evaluate the methodological quality of the instruments. Using the Cochrane approach, searches were conducted in Pubmed, EBSCOHost and Scopus from inception to February 2014. Papers were screened by two independent assessors, and data were extracted by one researcher. Forty papers reporting 34 instruments met the inclusion criteria and were included in the qualitative synthesis. Most instruments measured EBP behaviour (n = 33) and attitudes (n = 21). This review provides a single source of information to enable researchers to select the most robust descriptive instruments to measure EBP learner attributes. Instruments used only with occupational therapists may have resulted in some instruments being missed. For further research, it is recommended that attention is given to developing objective instruments with a focus on knowledge and skills. Copyright © 2015 John Wiley & Sons, Ltd.

  13. A novel automated instrument designed to determine photosensitivity thresholds (Conference Presentation)

    As there is no clinically available instrument to systematically and reliably determine the photosensitivity thresholds of patients with dry eyes, blepharospasms, migraines, traumatic brain injuries, and genetic disorders such as Achromatopsia, retinitis pigmentosa and other retinal dysfunctions, a computer-controlled optoelectronics system was designed. The BPEI Photosensitivity System provides a light stimuli emitted from a bi-cupola concave, 210 white LED array with varying intensity ranging from 1 to 32,000 lux. The system can either utilize a normal or an enhanced testing mode for subjects with low light tolerance. The automated instrument adjusts the intensity of each light stimulus. The subject is instructed to indicate discomfort by pressing a hand-held button. Reliability of the responses is tracked during the test. The photosensitivity threshold is then calculated after 10 response reversals. In a preliminary study, we demonstrated that subjects suffering from Achromatopsia experienced lower photosensitivity thresholds than normal subjects. Hence, the system can safely and reliably determine the photosensitivity thresholds of healthy and light sensitive subjects by detecting and quantifying the individual differences. Future studies will be performed with this system to determine the photosensitivity threshold differences between normal subjects and subjects suffering from other conditions that affect light sensitivity.

    NESSI: the New Mexico Tech Extrasolar Spectroscopic Survey Instrument is a ground-based multi-object spectrograph that operates in the near-infrared. It will be installed on one of the Nasmyth ports of the Magdalena Ridge Observatory (MRO) 2.4-meter Telescope sited in the Magdalena Mountains, about 48 km west of Socorro-NM. NESSI operates stationary to the telescope fork so as not to produce differential flexure between internal opto-mechanical components during or between observations. An appropriate mechanical design allows the instrument alignment to be highly repeatable and stable for both short and long observation timescales, within a wide-range of temperature variation. NESSI is optically composed of a field lens, a field de-rotator, re-imaging optics, an auto-guider and a Dewar spectrograph that operates at LN2 temperature. In this paper we report on NESSI's detailed mechanical and opto-mechanical design, and the planning for mechanical construction, assembly, integration and verification.

    Full Text Available Abstract Background Comprehensive, multi-level approaches are required to address obesity. One important target for intervention is the economic domain. The purpose of this study was to synthesize existing evidence regarding the impact of economic policies targeting obesity and its causal behaviours (diet, physical activity, and to make specific recommendations for the Canadian context. Methods Arksey and O'Malley's (2005 methodological framework for conducting scoping reviews was adopted for this study and this consisted of two phases: 1 a structured literature search and review, and 2 consultation with experts in the research field through a Delphi survey and an in-person expert panel meeting in April 2010. Results Two key findings from the scoping review included 1 consistent evidence that weight outcomes are responsive to food and beverage prices. The debate on the use of food taxes and subsidies to address obesity should now shift to how best to address practical issues in designing such policies; and 2 very few studies have examined the impact of economic instruments to promote physical activity and clear policy recommendations cannot be made at this time. Delphi survey findings emphasised the relatively modest impact any specific economic instrument would have on obesity independently. Based on empirical evidence and expert opinion, three recommendations were supported. First, to create and implement an effective health filter to review new and current agricultural polices to reduce the possibility that such policies have a deleterious impact on population rates of obesity. Second, to implement a caloric sweetened beverage tax. Third, to examine how to implement fruit and vegetable subsidies targeted at children and low income households. Conclusions In terms of economic interventions, shifting from empirical evidence to policy recommendation remains challenging. Overall, the evidence is not sufficiently strong to provide clear policy

    1999-12-01

    This study determined which types of laparoscopic instruments are most often used in Europe, why they are being used, and what problems exist while using the instruments. The handles were also evaluated according to ergonomic design criteria. A questionnaire was send to 62 experienced surgeons in 19 countries. The laparoscopic instruments were divided into four groups: instruments with similar functionality and handgrip model were grouped together. Eight questions were asked for every group about the type of instrument (disposable, reusable, or semireusable), the type of handle, the reason for using a specific instrument, and the experience of discomfort while using the instrument. The handles of the instruments of the group that were associated with the greatest discomfort were ergonomically evaluated on eight aspects (dimensions, angles, and control). Half of the questionnaires were returned. In every group, about 80% of the instruments the surgeons employed were reusable. The chief reason for using a specific type was the good cost-quality of the product and satisfying experiences with other products of the brand. The discomfort was pressure on thumb and fingers (scissors handle) and fixating the tip (ratchet). The handle of the instruments that causes the most discomfort met only three of the eight ergonomic requirements. Most of the laparoscopic instruments employed by surgeons in Europe are reusable. A significant number of the instruments cause discomfort. These instruments do not meet standard ergonomic requirements.

    Heinemann, A W; Bode, R K; O'Reilly, C

    2003-12-01

    The need to measure and evaluate orthotics and prosthetics (O&P) practice has received growing recognition in the past several years. Reliable and valid self-report instruments are needed that can help facilities evaluate patient outcomes. The objective of this project was to develop a set of self-report instruments that assess functional status, quality of life, and satisfaction with devices and services that can be used in an orthotics and prosthetics clinic. Selecting items from a variety of existing instruments, the authors developed and revised four instruments that differentiate patients with varying levels of lower limb function, quality of life, and satisfaction with devices and services. Evidence of construct validity is provided by hierarchies of item difficulty that are consistent with clinical experience. For example, with the lower limb function instrument, running one block was much more difficult than walking indoors. The instruments demonstrate adequate internal consistency (0.88 for lower limb function, 0.88 for quality of life, 0.74 for service satisfaction, 0.78 for device satisfaction). The next steps in their research programme are to evaluate sensitivity and construct validity. The Orthotics and Prosthetics Users' Survey (OPUS) is a promising self-report instrument which may, with further development, allow orthotic and prosthetic practitioners to evaluate the quality and effectiveness of their services as required by accreditation standards such as those of the American Board for Certification in Orthotics and Prosthetics that mandate quality assessment.

    The global burden of headache is very large, but knowledge of it is far from complete and needs still to be gathered. Published population-based studies have used variable methodology, which has influenced findings and made comparisons difficult. The Global Campaign against Headache is undertaking initiatives to improve and standardize methods in use for cross-sectional studies. One requirement is for a survey instrument with proven cross-cultural validity. This report describes the development of such an instrument. Two of the authors developed the initial version, which was used with adaptations in population-based studies in China, Ethiopia, India, Nepal, Pakistan, Russia, Saudi Arabia, Zambia and 10 countries in the European Union. The resultant evolution of this instrument was reviewed by an expert consensus group drawn from all world regions. The final output was the Headache-Attributed Restriction, Disability, Social Handicap and Impaired Participation (HARDSHIP) questionnaire, designed for application by trained lay interviewers. HARDSHIP is a modular instrument incorporating demographic enquiry, diagnostic questions based on ICHD-3 beta criteria, and enquiries into each of the following as components of headache-attributed burden: symptom burden; health-care utilization; disability and productive time losses; impact on education, career and earnings; perception of control; interictal burden; overall individual burden; effects on relationships and family dynamics; effects on others, including household partner and children; quality of life; wellbeing; obesity as a comorbidity. HARDSHIP already has demonstrated validity and acceptability in multiple languages and cultures. Modules may be included or not, and others (e.g., on additional comorbidities) added, according to the purpose of the study and resources (especially time) available.

    2017-08-01

    Following the Fukushima Dai-ichi Nuclear Power Plant accident in March 2011, extensive radiation monitoring and environmental clean-up activities have been conducted throughout the Fukushima region. Outside air temperatures there reach 40 °C in summer and -20 °C in winter, which are beyond the quoted operational range of many radiation survey instruments. Herein, temperature performance of four types of portable Japanese radiation survey instruments widely used in Fukushima was experimentally investigated using a temperature-controlled chamber. They included two ionization chamber type instruments, Fuji NHA1 and Aloka ICS-323C, and two NaI(Tl) scintillation type ones, Fuji NHC7 and Aloka TCS-172B. Experimental results showed significantly diverse characteristics on the temperature dependences from one type of instrument to another. For example, NHA1 overestimated the ambient dose-equivalent rate by as much as 17% at -30 °C and 10% at 40 °C, whereas the TCS-172B readings underestimated the rate by 30% at -30 °C and 7% at 40 °C.

    Hospitals currently rely on simple human visual inspection for assessing cleanliness of surgical instruments. Studies showed that surgical site infections are in part attributed to inadequate cleaning of medical devices. Standards groups recognize the need to objectively quantify the amount of residues on surgical instruments and establish guidelines. We developed a portable technology for the detection of contaminants on surgical instruments through fluorescence following cleaning. Weak fluorescence signals are usually detected in the obscurity only with the lighting of the excitation source. The key element of this system is that it works in ambient lighting conditions, a requirement to not disturb the normal workflow of hospital reprocessing facilities. A biocompatible fluorescent dye is added to the detergent and labels the proteins of organic residues. It is resistant to the harsh environment in a washer-disinfector. Two inspection devices have been developed with a 488nm laser as the excitation source: a handheld scanner and a tabletop station using spectral-domain and time-domain ambient light cancellation schemes. The systems are eye safe and equipped with image processing and interfacing software to provide visual or audible warnings to the operator based on a set of adjustable signal thresholds. Micron-scale residues are detected by the system which can also evaluate soil size and mass. Unlike swabbing, it can inspect whole tools in real-time. The technology has been validated in an independent hospital decontamination research laboratory. It also has potential applications in the forensics, agro-food, and space fields. Technical aspects and results will be presented and discussed.

    Open clusters (OCs) are crucial for studying the formation and evolution of the Galactic disc. However, the lack of a large number of OCs analyzed homogeneously hampers the investigations about chemical patterns and the existence of Galactocentric radial and vertical gradients, or an age-metallicity relation. To overcome this, we have designed the Open Cluster Chemical Abundances from Spanish Observatories survey (OCCASO). We aim to provide homogeneous radial velocities, physical parameters and individual chemical abundances of six or more Red Clump stars for a sample of 25 old and intermediate-age OCs visible from the Northern hemisphere. To do so, we use high resolution spectroscopic facilities (R> 62,000) available at Spanish observatories. We present the motivation, design and current status of the survey, together with the first data release of radial velocities for 77 stars in 12 OCs, which represents about 50% of the survey. We include clusters never studied with high-resolution spectroscopy before (NG...

    Developments in the remote detection of trace gases in the atmosphere using Differential Absorption Lidar have been driven largely by improvements in two key technologies: lasers and detectors. We have designed and built a narrow linewidth pulsed laser source with a well-controlled output wavelength and sufficient pulse energy to measure the concentration profile of CO2 and CH4 to a range in excess of 4km. We describe here the initial measurements of concentration profiles recorded with this instrument. The system is built around a custom-designed Newtonian telescope with a 40cm diameter primary mirror. Laser sources and detectors attach directly to the side of the telescope allowing for flexible customization with a range of additional equipment. The instrument features an all-solid-state laser source based on an optical parametric oscillator (OPO) pumped by an YLF based diode-laser pumped solid-state laser and seeded by a tuned DFB seed. This provides a range of available wavelengths suitable for DIAL within the 1.5-1.6 μm spectral region. The output of the OPO is beam expanded and transmitted coaxially from the receiver telescope. A gas cell within the laser source controls the seed wavelength and allows the wavelength to be tuned to match a specific absorption feature of the selected gas species. The source can be rapidly tuned between the on-line and off-line wavelengths to make a DIAL measurement of either CO2 or CH4 The receiver is based on an InGaAs avalanche photodetector. Whilst photodiode detectors are a low-cost solution their limited sensitivity restricts the maximum range over which a signal can be detected. The receiver signal is digitised for subsequent processing to produce a sightline concentration profile. The instrument is mounted on a robust gimballed mount providing full directional movement within the upper hemisphere. Both static pointing and angular scan modes are available. Accurate angular position is available giving the sightline

    Despite the health benefits associated with children's sport participation, the occurrence of injury in this context is common. The extent to which sport injuries impact children's ongoing involvement in sport is largely unknown. Surveys have been shown to be useful for collecting children's injury and sport participation data; however, there are currently no published instruments which investigate the impact of injury on children's sport participation. This study describes the processes undertaken to assess the validity of two survey instruments for collecting self-reported information about child cricket and netball related participation, injury history and injury risk perceptions, as well as the reliability of the cricket-specific version. Face and content validity were assessed through expert feedback from primary and secondary level teachers and from representatives of peak sporting bodies for cricket and netball. Test-retest reliability was measured using a sample of 59 child cricketers who completed the survey on two occasions, 3-4 weeks apart. Based on expert feedback relating to face and content validity, modification and/or deletion of some survey items was undertaken. Survey items with low test-retest reliability (κ≤0.40) were modified or deleted, items with moderate reliability (κ=0.41-0.60) were modified slightly and items with higher reliability (κ≥0.61) were retained, with some undergoing minor modifications. This is the first survey of its kind which has been successfully administered to cricketers aged 10-16 years to collect information about injury risk perceptions and intentions for continued sport participation. Implications for its generalisation to other child sport participants are discussed.

    A practical, reliable, and valid instrument is needed to measure the impact of the learning environment on medical students' well-being and educational experience and to meet medical school accreditation requirements. From 2012 to 2015, medical students were surveyed at the end of their first, second, and third year of studies at four medical schools. The survey assessed students' perceptions of the following nine dimensions of the school culture: vitality, self-efficacy, institutional support, relationships/inclusion, values alignment, ethical/moral distress, work-life integration, gender equity, and ethnic minority equity. The internal reliability of each of the nine dimensions was measured. Construct validity was evaluated by assessing relationships predicted by our conceptual model and prior research. Assessment was made of whether the measurements were sensitive to differences over time and across institutions. Six hundred and eighty-six students completed the survey (49 % women; 9 % underrepresented minorities), with a response rate of 89 % (range over the student cohorts 72-100 %). Internal consistency of each dimension was high (Cronbach's α 0.71-0.86). The instrument was able to detect significant differences in the learning environment across institutions and over time. Construct validity was supported by demonstrating several relationships predicted by our conceptual model. The C-Change Medical Student Survey is a practical, reliable, and valid instrument for assessing the learning environment of medical students. Because it is sensitive to changes over time and differences across institution, results could potentially be used to facilitate and monitor improvements in the learning environment of medical students.

    Through the SNL New Mexico Small Business Assistance (NMSBA) program, several Sandia engineers worked with the Environmental Restoration Group (ERG) Inc. to verify and validate a novel algorithm used to determine the scanning Critical Level (L c ) and Minimum Detectable Concentration (MDC) (or Minimum Detectable Areal Activity) for the 102F scanning system. Through the use of Monte Carlo statistical simulations the algorithm mathematically demonstrates accuracy in determining the L c and MDC when a nearest-neighbor averaging (NNA) technique was used. To empirically validate this approach, SNL prepared several spiked sources and ran a test with the ERG 102F instrument on a bare concrete floor known to have no radiological contamination other than background naturally occurring radioactive material (NORM). The tests conclude that the NNA technique increases the sensitivity (decreases the L c and MDC) for high-density data maps that are obtained by scanning radiological survey instruments.

The question is what causes consumers choose certain convenience store to buy RTE Product and not choose another outlet category. To understand consumer perceptions, it is necessary to develop an instrument for measuring consumer perceptions of the option to purchase RTE Product at convenience stores. Variables used in this research are the perception and knowledge of the public/consumers against food safety, store attributes, service, and product attributes. The instrument used in this study is a questionnaire with a scalemeasuring1-5 to see the relationship between variables, we used the method of Structural Equation Modeling (SEM. The sample used in this study was 223 respondents that were divided into five areas in Jakarta, namely Central Jakarta, West Jakarta, South Jakarta, East Jakarta, and North Jakarta. The final outcome of the instrument development process was 25 observed variables, consisting of 4 indicators, which valid and reliable, with T-values for each observed variable is above 2,58, and Construct Reliability values range between 0,76 to 0,853.

We have chosen the theme “The life and work of Prof. Dr. Jürgen Moltmann” as its special emphasis. It is our way to pay homage to J. Moltmann in the year the Universidade Metodista de São Paulo awards him an honorary Doctor Honoris Causa degree. Sincethe seventies, Moltmann and Latin America have been in dialog. In his emblematic work “A Theology of Liberation”, Gustavo Gutiérrez, the Catholic, discussed with Moltmann, the Reformed, the relationship between eschatology and history (GUTIÉRREZ, Gustavo.Teologia da Libertação. 5ª edição. Petrópolis, RJ: Vozes, 1985, p. 27, 137-139. A dialog held in the premises of IMS, which nowadays is called UMESP, has produced the little book “Passion for life” (MOLTMANN, Jürgen. Paixão pela vida. São Paulo, SP: ASTE - Associaçãode Seminários Teológicos Evangélicos, 1978.In the following years, the wide theological work of J. Moltmann went all the way from debates to congresses and has conquered the classrooms. Most probably, J. Moltmann is nowadays the most widely read European author in Brazilian theological seminaries. Thisrecognition can only be held in unison and the wide response to our request for articles confirms the huge repercussion that Moltmann’s work has been having up to today in Brazil. The ecumenical theologian J. Moltmann is ecumenically read. We believe that thisway we may be better equipped to answer to anyone who asks us for the reason there is hope in us. We have organized the articles on J. Moltmann’s theology according to the original publication date of the books dealt with in each essay. We also communicate that some articles which were originally requested for this edition of the journal will be published in the journal Estudos de Regilião in May 2009.As it is usual with the journal Caminhando, we have, besides this thematic emphasis, yet other contributions in the areas of

    Information systems (IS) benefits for nurses are outcomes related to the tangible products or improvements that nurses realize from using IS. This study examined the development and psychometric testing of a measure of nurses' benefits from IS. A random sample of 570 nurses working in hospitals, providing direct patient care, and using IS completed the study questionnaire. The internal consistency reliability of the results was .97. Exploratory factor analysis, using principal components extraction and varimax rotation, revealed items loaded on four factors (saving time and efficiency, quality of care, charting, and professional practice) that were confirmed by confirmatory factor analysis. Continued refinement of the instrument is needed with more diverse samples of nurses.

    Coalitions are often composed of member organizations. Member involvement is thought to be associated with coalition success. No instrument currently exists for evaluating organizational member involvement in physical activity coalitions. This study aimed to develop a survey instrument for evaluating organizational member involvement in physical activity coalitions. The study was carried out in three phases: (a) developing a draft survey, (b) assessing the content validity of the draft survey, and (c) assessing the underlying factor structure, reliability, and validity of the survey. A cross-sectional design was employed. In Phase 1, a team of experts in survey development produced a draft survey. In Phase 2, the content validity of the draft survey was evaluated by a panel of individuals with expertise in physical activity coalitions. In Phase 3, the survey was administered to 120 individuals on local-, state-, and national-level physical activity coalitions. Responses were subjected to an exploratory factor analysis in order to determine the survey's underlying factor structure, reliability, and validity. Phases 1 and 2yielded a survey instrument with demonstrated content validity. Phase 3 yielded a three-factor model with three subscales: Strategic Alignment, Organizational Alignment, and Providing Input. Each subscale demonstrated high internal consistency reliability and construct validity. The survey instrument developed here demonstrated sound psychometric properties and provides new insight into organizational member involvement in physical activity coalitions. This instrument may be an important tool in developing a more complete picture of coalition functioning in physical activity coalitions specifically and health-based coalitions overall. © 2014 Society for Public Health Education.

This survey has been undertaken by EFOMP in 2005, to update the document "Policy Statement No. 1", which represents the starting point of the EFOMP recommendations on Education and Training in Medical Physics. Ultimate results have been collected at the end of 2006. To perform the survey, a questionnaire was sent to 34 National Member Organisations (NMOs) for Medical Physics, to collect information on the present state of education and training in each European country. Twenty-five countries participated in the enquiry and responded to it. The most outstanding results are as follows: In all countries, the basic requirement to enter the Medical Physics education is a university degree. The length of this university education ranges from 2 to 5 years. Concerning the Post-graduate education in Medical Physics: A nationally approved educational programme is in operation in 16 of the 25 countries. Postgraduate education takes place essentially within 3 different approaches and the total length of Medical Physics education and training ranges from 2 1/2 years to 9 years. In 14 countries, it is mandatory to hold a diploma or license to work as a Medical Physicist. It allows working in all areas of competence (the most mentioned were Radiotherapy, Nuclear Medicine, Diagnostic Radiology and Radiation Protection) in 14 countries, whereas in 4 countries it allows to work only in 1 or 2 areas. Seventeen countries have a register for Medical Physicists. A formal CPD (Continuing Professional Development) programme is in operation in 13 countries.

    We explored the psychometric properties of 15 survey questions that assessed abortion providers' perceptions of stigma and its impact on providers' professional and personal lives referred to as the Abortion Provider Stigma Survey (APSS). We administered the survey to a sample of abortion providers recruited for the Providers' Share Workshop (N = 55). We then completed analyses using Stata SE/12.0. Exploratory factor analysis, which resulted in 13 retained items and identified three subscales: disclosure management, resistance and resilience, and discrimination. Stigma was salient in abortion provider's lives: they identified difficulties surrounding disclosure (66%) and felt unappreciated by society (89%). Simultaneously, workers felt they made a positive contribution to society (92%) and took pride in their work (98%). Paired t-test analyses of the pre- and post-Workshop APSS scores showed no changes in the total score. However, the Disclosure Management subscale scores were significantly lower (indicating decreased stigma) for two subgroups of participants: those over the age of 30 and those with children. This analysis is a promising first step in the development of a quantitative tool for capturing abortion providers' experiences of and responses to pervasive abortion stigma.

    We present initial results from the Herschel GT key program: Herschel observations of EXtra-Ordinary Sources (HEXOS) and outline the promise and potential of spectral surveys with Herschel/HIFI. The HIFI instrument offers unprecedented sensitivity, as well as continuous spectral coverage across the gaps imposed by the atmosphere, opening up a largely unexplored wavelength regime to high-resolution spectroscopy. We show the spectrum of Orion KL between 480 and 560 GHz and from 1.06 to 1.115 THz. From these data, we confirm that HIFI separately measures the dust continuum and spectrally resolves emission lines in Orion KL. Based on this capability we demonstrate that the line contribution to the broad-band continuum in this molecule-rich source is ~20-40% below 1 THz and declines to a few percent at higher frequencies. We also tentatively identify multiple transitions of HD18O in the spectra. The first detection of this rare isotopologue in the interstellar medium suggests that HDO emission is optically thick i...

    The aim of this study was to describe the initial stages of the cross-cultural adaptation of the instrument The Vulnerable Elders Survey (VES-13) for use in the context of cancer care in Brazil. Two translations into Portuguese and two back-translations into English were carried out independently, and a formal assessment of the general and referential meanings was performed in order to obtain a synthesis version. Understanding of the synthesis version was evaluated in a pretest applied to 33 patients in an oncologic hospital of the Brazilian Unified National Health System (SUS). The version was easily applied in the intended context and was well-accepted by elders. The Portuguese version of the VES-13 proved to be well understood and adequate for testing its psychometric qualities. The latter step is currently in the final phase.

    The town of Mesagne is one of the sites at greatest geological risk in the north Salento peninsula. In the last few decades, the historical centre of Mesagne has been affected by a series of subsidence events, which have, in some cases, resulted in the partial collapse of buildings and road surfaces. The last event was in the January 2014. It caused subsidence phenomenon in a wide area and many families have been forced from their homes. These events have had both social repercussions, causing alarm and emergency situations, and economic repercussions in terms of the expense of restoration. In order to determine the causes of the ground subsidence events, integrated geophysical surveys were undertaken in the historical centre of Mesagne. In addition, the analysis of several wells allowed the 3D model reconstruction related both to the geology and to the groundwater depth in the surveyed areas. With the purpose of estimating the dimensions of the phenomenon and its possible relationship with both specific environmental conditions (for instance groundwater depth variation) and anthropic conditions (for instance the losses in water supply and sanitation) some geophysical measurements were repeated in the time. For this purpose a modified ERT instrumentation together GPR were used. The study led to the production of a detailed description of the subsidence causes that allows a quick action to restore security conditions in the area.

    The paper integrates some earlier and the recent findings of the author in the area of network internal reliability and presents a consistent system of concepts in this respect. The concepts of outlier detection and outlier identification linked directly with the global model test and the outlier tests respectively, are shown as a basis for the concepts such as outlier detectability and outlier identifiability. Also, a four level classification of gross errors expressed in a form of a tree-diagram is presented including perceptible and imperceptible errors, detectable and undetectable errors and identifiable and unidentifiable errors. Their properties are given mainly in a descriptive way, deliberately limiting rigorous mathematical formulas to a necessary minimum. Understanding of different types of gross errors is useful in analyzing the results of the outlier detection and identification procedures as well as in designing the networks to make them duly robust to observation gross errors. It is of special importance for engineering surveys where quite often low-redundancy networks are used. Main objective of the paper is to demonstrate a clear and consistent system of basic concepts related to network internal reliability.

    Full Text Available Background Clinical data are collected for routine care in family practice; there are also a growing number of genetic and cancer registry data repositories. The Translational Research and Patient Safety in Europe (TRANSFoRm project seeks to facilitate research using linked data from more than one source. We performed a requirements analysis which identified a wide range of data and business process requirements that need to be met before linking primary care and either genetic or disease registry data.Objectives To develop a survey to assess the readiness of data repositories to participate in linked research – the Transform International Research Readiness (TIRRE survey.Method We develop the questionnaire based on our requirement analysis; with questions at micro-, meso- and macro levels of granularity, study-specific questions about diabetes and gastro-oesophageal reflux disease (GORD, and research track record. The scope of the data required was extensive. We piloted this instrument, conducting ten preliminary telephone interviews to evaluate the response to the questionnaire.Results Using feedback gained from these interviews we revised the questionnaire; clarifying questions that were difficult to answer and utilising skip logic to create different series of questions for the various types of data repository. We simplified the questionnaire replacing free-text responses with yes/no or picking list options, wherever possible. We placed the final questionnaire online and encouraged its use (www.clininf.eu/jointirre/info.html.Conclusion Limited field testing suggests that TIRRE is capable of collecting comprehensive and relevant data about the suitability and readiness of data repositories to participate in linked data research.

    Full Text Available Since the 13th Association of Southeast Asian Nations (ASEAN Summit in November 2007, held in Singapore, ASEAN has accelerated its response to climate change issues, including REDD+ as a mechanism for climate change mitigation and adaptation, and to enhance conservation and sustainable use of natural resources. There are many wetlands in ASEAN including more than 25 million ha of peatlands spread over Indonesia, Malaysia, Thailand, Brunei, Philippines, Vietnam and Lao PDR. The peatlands account for 60 per cent of global tropical peatland resources. They are of significance for sequestration of carbon. However, degraded wetlands, including peatlands, are also a major source of greenhouse gases contributing to global warming. Of the types of wetlands, ASEAN has focused attention predominantly on peatlands in relation to REDD+, mainly because of the ‘Indonesian Haze’. The Asia-Pacific Centre for Environmental Law (APCEL organised a Workshop titled, REDD+ and Legal Regimes of Mangroves, Peatland and Other Wetlands: ASEAN and the World, in Singapore from 15-16 November 2012. The articles contained in this special themed edition of the International Journal of Rural Law and Policy (IJRLP contains a selection of the papers presented. This editorial will provide a brief background to some aspects of REDD+. Included in this issue of IJRLP is a summary of the proceedings of the workshop as interpreted by the assigned rapporteur and editors of APCEL. These summaries were reviewed and approved by the presenters.

  20. Patient experience and satisfaction with inpatient service: development of short form survey instrument measuring the core aspect of inpatient experience.

    Full Text Available Patient experience reflects quality of care from the patients' perspective; therefore, patients' experiences are important data in the evaluation of the quality of health services. The development of an abbreviated, reliable and valid instrument for measuring inpatients' experience would reflect the key aspect of inpatient care from patients' perspective as well as facilitate quality improvement by cultivating patient engagement and allow the trends in patient satisfaction and experience to be measured regularly. The study developed a short-form inpatient instrument and tested its ability to capture a core set of inpatients' experiences. The Hong Kong Inpatient Experience Questionnaire (HKIEQ was established in 2010; it is an adaptation of the General Inpatient Questionnaire of the Care Quality Commission created by the Picker Institute in United Kingdom. This study used a consensus conference and a cross-sectional validation survey to create and validate a short-form of the Hong Kong Inpatient Experience Questionnaire (SF-HKIEQ. The short-form, the SF-HKIEQ, consisted of 18 items derived from the HKIEQ. The 18 items mainly covered relational aspects of care under four dimensions of the patient's journey: hospital staff, patient care and treatment, information on leaving the hospital, and overall impression. The SF-HKIEQ had a high degree of face validity, construct validity and internal reliability. The validated SF-HKIEQ reflects the relevant core aspects of inpatients' experience in a hospital setting. It provides a quick reference tool for quality improvement purposes and a platform that allows both healthcare staff and patients to monitor the quality of hospital care over time.

    Full Text Available Abstract Background A frailty paradigm would be useful in primary care to identify older people at risk, but appropriate metrics at that level are lacking. We created and validated a simple instrument for frailty screening in Europeans aged ≥50. Our study is based on the first wave of the Survey of Health, Ageing and Retirement in Europe (SHARE, http://www.share-project.org, a large population-based survey conducted in 2004-2005 in twelve European countries. Methods Subjects: SHARE Wave 1 respondents (17,304 females and 13,811 males. Measures: five SHARE variables approximating Fried's frailty definition. Analyses (for each gender: 1 estimation of a discreet factor (DFactor model based on the frailty variables using LatentGOLD®. A single DFactor with three ordered levels or latent classes (i.e. non-frail, pre-frail and frail was modelled; 2 the latent classes were characterised against a biopsychosocial range of Wave 1 variables; 3 the prospective mortality risk (unadjusted and age-adjusted for each frailty class was established on those subjects with known mortality status at Wave 2 (2007-2008 (11,384 females and 9,163 males; 4 two web-based calculators were created for easy retrieval of a subject's frailty class given any five measurements. Results Females: the DFactor model included 15,578 cases (standard R2 = 0.61. All five frailty indicators discriminated well (p N = 10,420; 66.9%, pre-frail (N = 4,025; 25.8%, and frail (N = 1,133; 7.3%. Relative to the non-frail class, the age-adjusted Odds Ratio (with 95% Confidence Interval for mortality at Wave 2 was 2.1 (1.4 - 3.0 in the pre-frail and 4.8 (3.1 - 7.4 in the frail. Males: 12,783 cases (standard R2 = 0.61, all frailty indicators had p N = 10,517; 82.3%, pre-frail (N = 1,871; 14.6%, and frail (N = 395; 3.1%; age-adjusted OR (95% CI for mortality: 3.0 (2.3 - 4.0 in the pre-frail, 6.9 (4.7 - 10.2 in the frail.

    The flux is still a major limiting factor in neutron research. For instruments being supplied by cold neutrons using neutron guides, both at present steady-state and at new spallation neutron sources, it is therefore important to optimize the instrumental setup and the neutron guidance. Optimization of neutron guide geometry and of the instrument itself can be performed by numerical ray-tracing simulations using existing open-access codes. In this paper, we discuss how such Monte Carlo simulations have been employed in order to plan improvements of the Neutron Resonant Spin Echo spectrometer RESEDA (FRM II, Germany) as well as the neutron guides before and within the instrument. The essential components have been represented with the help of the McStas ray-tracing package. The expected intensity has been tested by means of several virtual detectors, implemented in the simulation code. Comparison between simulations and preliminary measurements results shows good agreement and demonstrates the reliability of the numerical approach. These results will be taken into account in the planning of new components installed in the guide system.

    This paper reports a pilot study of Context Evaluation using a self-developed questionnaire distributed among engineering undergraduates at a university under study. The study aims to validate the self-developed questionnaires used in the Context evaluation, a component in the CIPP Model. The Context evaluation assesses background information for needs, assets, problems and opportunities relevant to beneficiaries of the study in a defined environment. Through the questionnaire, background information for the assessment of needs, assets and problems related to the engineering undergraduates' perceptions on the teaching and learning of technical oral presentation skills was collected and analysed. The questionnaire was developed using 5-points Likert scale to measure the constructs under study. They were distributed to 100 respondents with 79 returned. The respondents consisted of engineering undergraduates studied at various faculties at one technical university in Malaysia. The descriptive analysis of data for each item which makes up the construct for Context evaluation is found to be high. This implied that engineering undergraduates showed high interest in teaching and learning of technical oral presentation skills, thus their needs are met. Also, they agreed that assets and facilities are conducive to their learning. In conclusion, the context evaluation involving needs and assets factors are both considerably important; their needs are met and the assets and facilities do support their technical oral presentation skills learning experience.

    2013-07-01

    Wind industry has been challenged by premature subsystem/component failures. Various reliability data collection efforts have demonstrated their values in supporting wind turbine reliability and availability research & development and industrial activities. However, most information on these data collection efforts are scattered and not in a centralized place. With the objective of getting updated reliability statistics of wind turbines and/or subsystems so as to benefit future wind reliability and availability activities, this report is put together based on a survey of various reliability databases that are accessible directly or indirectly by NREL. For each database, whenever feasible, a brief description summarizing database population, life span, and data collected is given along with its features & status. Then selective results deemed beneficial to the industry and generated based on the database are highlighted. This report concludes with several observations obtained throughout the survey and several reliability data collection opportunities in the future.

    In an effort to better understand the details of the stellar structure and evolution of metal-poor stars, the Gemini North telescope was used on two occasions to take speckle imaging data of a sample of known spectroscopic binary stars and other nearby stars in order to search for and resolve close companions. The observations were obtained using the Differential Speckle Survey Instrument, which takes data in two filters simultaneously. The results presented here are of 90 observations of 23 systems in which one or more companions was detected, and six stars where no companion was detected to the limit of the camera capabilities at Gemini. In the case of the binary and multiple stars, these results are then further analyzed to make first orbit determinations in five cases, and orbit refinements in four other cases. The mass information is derived, and since the systems span a range in metallicity, a study is presented that compares our results with the expected trend in total mass as derived from the most recent Yale isochrones as a function of metal abundance. These data suggest that metal-poor main-sequence stars are less massive at a given color than their solar-metallicity analogues in a manner consistent with that predicted from the theory.

    Although we know a great deal about the percentage of youth who drink alcohol, we know very little about the specific brands they choose to drink. This information gap needs to be addressed if public health officials are to develop more effective interventions. Unfortunately, there are no national youth surveys that collect data on alcohol brand consumption. In this paper, we describe the development and pilot testing of what we believe to be the first comprehensive, Internet-based youth survey of brand-specific alcohol use. We used online advertising in 3 U.S. cities to recruit a convenience sample of 241 respondents, ages 16 to 18 years. We used Craigslist, a network of online communities that features local classified advertisements, to recruit the sample. We used SurveyGizmo, an online software program for designing Internet surveys, collecting data, and performing basic analysis, to survey these respondents about their brand-specific alcohol consumption patterns. The survey instrument assessed each respondent's 30-day drinking history, including the frequency of consumption for each alcohol brand. Using Internet survey technology, we were able to collect information on 366 brands and still have respondents complete the instrument quickly and easily. The total number of brands consumed in the past 30 days ranged from 1 to 18, with a median of 4 brands. The top 5 brands consumed were beer brands, as were eleven of the top 15 brands. The remaining 4 brands in the top 15 included 3 brands of flavored alcoholic beverages and 1 brand of mixed drink. Among the top 15 alcohol brands consumed during heavy drinking episodes were 8 brands of beer, 4 brands of flavored alcoholic beverages, 2 brands of wine, and 1 brand of mixed drink. This pilot study helps establish the feasibility of including brand-specific questions on federal or other national youth alcohol surveys. Copyright © 2011 by the Research Society on Alcoholism.

    2013-09-01

    Full Text Available The study deals with the activity carried on within the Office of Studies and Polls of the Romanian Radiotelevision during Communism and, at the same time, with the relation between the Office and the official propaganda. The Office was inaugurated in 1967 and was managed by the Marxist historian and sociologist Pavel Câmpeanu. The surveys conducted by its members were perceived as a form of mediation between the Romanian Television and its audience that still evinced, at that time, the (relative freedom of speech of the TV-viewers, in general. At the beginning of the 1970s, however, the political pressure and the wooden discourse of the Communist propaganda took over audio - visual media. The importance of the surveys and of their results rests on the conveyance of the social echo that the pro - Ceauşescu propaganda had. Nonetheless, they reveal that, in terms of popularity, the social visibility of the Romanian Television was broadened thanks to TV shows that provided entertainment, and not to those which pursued ideology. This paper focuses on an analysis undertaken by the members of the Office of Studies and Polls in 1969, concerning the public opinion about the schedules of the radio and television broadcasts.

    Environmental reporting is increasingly important for medical facilities. Currently, hospitals can determine the content of an environmental report as they see fit. To examine the utility and scope of an employee survey as an instrument for the preparation of an environmental report at the University Hospital Greifswald. For this purpose a questionnaire was developed with a focus on environmental behaviour and the significance attached to the protection of the environment. The employees of the University Medicine Greifswald attach an unexpectedly high significance to the protection of the environment. Based on this finding, this potential should be used to promote the optimal implementation of ecological-economic behaviour within the University Medicine. An employee survey is a useful instrument in the preparation of an environmental report.

    Many developed and used conventional survey methods are applicable for Gio Front project related survey. However, more complicated measuring instruments might be in need under the deeper and defficult situations. The figure adjustment and the analysis in the simulation have to be carefully studied as this project is nothing like the previous architectual experience. Because of the purpose of this project, it is very important to consider about environmental care not only the blue print and the building methods of underground space.

    Objectives To investigate practicing physicians' preferences, perceived usefulness and understanding of a new multilayered guideline presentation format—compared to a standard format—as well as conceptual understanding of trustworthy guideline concepts. Design Participants attended a standardised lecture in which they were presented with a clinical scenario and randomised to view a guideline recommendation in a multilayered format or standard format after which they answered multiple-choice questions using clickers. Both groups were also presented and asked about guideline concepts. Setting Mandatory educational lectures in 7 non-academic and academic hospitals, and 2 settings involving primary care in Lebanon, Norway, Spain and the UK. Participants 181 practicing physicians in internal medicine (156) and general practice (25). Interventions A new digitally structured, multilayered guideline presentation format and a standard narrative presentation format currently in widespread use. Primary and secondary outcome measures Our primary outcome was preference for presentation format. Understanding, perceived usefulness and perception of absolute effects were secondary outcomes. Results 72% (95% CI 65 to 79) of participants preferred the multilayered format and 16% (95% CI 10 to 22) preferred the standard format. A majority agreed that recommendations (multilayered 86% vs standard 91%, p value=0.31) and evidence summaries (79% vs 77%, p value=0.76) were useful in the context of the clinical scenario. 72% of participants randomised to the multilayered format vs 58% for standard formats reported correct understanding of the recommendations (p value=0.06). Most participants elected an appropriate clinical action after viewing the recommendations (98% vs 92%, p value=0.10). 82% of the participants considered absolute effect estimates in evidence summaries helpful or crucial. Conclusions Clinicians clearly preferred a novel multilayered presentation format to the

    Improving the transparency of information about the quality of health care providers is one way to improve health care quality. It is assumed that Internet information steers patients toward better-performing health care providers and will motivate providers to improve quality. However, the effect of public reporting on hospital quality is still small. One of the reasons is that users find it difficult to understand the formats in which information is presented. We analyzed the presentation of risk-adjusted mortality rate (RAMR) for coronary angiography in the 10 most commonly used German public report cards to analyze the impact of information presentation features on their comprehensibility. We wanted to determine which information presentation features were utilized, were preferred by users, led to better comprehension, and had similar effects to those reported in evidence-based recommendations described in the literature. The study consisted of 5 steps: (1) identification of best-practice evidence about the presentation of information on hospital report cards; (2) selection of a single risk-adjusted quality indicator; (3) selection of a sample of designs adopted by German public report cards; (4) identification of the information presentation elements used in public reporting initiatives in Germany; and (5) an online panel completed an online questionnaire that was conducted to determine if respondents were able to identify the hospital with the lowest RAMR and if respondents' hospital choices were associated with particular information design elements. Evidence-based recommendations were made relating to the following information presentation features relevant to report cards: evaluative table with symbols, tables without symbols, bar charts, bar charts without symbols, bar charts with symbols, symbols, evaluative word labels, highlighting, order of providers, high values to indicate good performance, explicit statements of whether high or low values indicate

    The use of displacement values (DVs) when preparing intravenous (IV) medication for children enables accurate doses to be given1 and is assumed to be common paediatric practice. This survey aimed to assess views of UK paediatric pharmacists on DVs in practice to explore:▸ How prevalent is DV use in the paediatric hospital setting▸ Which type of IV administration guidelines were being used▸ Which form of DV presentation is perceived to be most practical▸ Which method of calculation is preferred A national cross-sectional survey study was undertaken. The questionnaire comprised of 13 closed and open questions as well as samples of how DVs are currently displayed on the Medusa Injectable Medicines Guide2. After piloting the questionnaire the survey was sent to 365 paediatric pharmacists across 120 UK hospitals utilising Qualtrics Survey Software. Fifty-five completed questionnaires covering 52 (43%) United Kingdom (UK) hospital trusts were received. Of 55 respondents, 52 (95%) reported the clinical significance of DVs in paediatric care. This was reflected in the fact that all local guides provided information on DVs. The majority (32;59%) used locally produced guides, while 15 (27%) of respondents used Medusa as a resource. All respondents commented on methods of presentation and calculation of DV information. Of four methods presented, the method involving presentation of reconstitution information in a brand-specific table was ranked as most practical (46;84% respondents). This method was viewed as being clear and concise. Respondents also expressed the importance of having this tabulated method visually embedded in the monograph to allow easy access to information on the wards. This concurs with suggested information presentation to aid error reduction in the literature.3 National standardisation of DV information was viewed as 'very useful' or 'preferred' by 52 (95%) of respondents; reasons for this preference were risk reduction due to errors or

    Piezoelectric ultrasonic motors have been investigated for several years and have already found their first practical applications. Their key feature is that they are able to produce a high thrust force related to their volume. Beside rotary drives like the travelling wave motor, linear drives have also been developed, but only a few are presently commercially available. In the present paper, we first describe the state of the art of linear piezoelectric motors. The motors are characterized with respect to their no-load velocity, maximum thrust force, efficiency and other technical properties. In the second part, we present a new motor, which is judged to be capable of surpassing the characteristics of other piezoelectric motors because of its unique design which allows the piezoelectric drive elements to be pre-stressed in the direction of their polarization. The piezoelectric elements convert energy using the longitudinal d33 effect which allows an improved reliability, large vibration amplitudes and excellent piezoelectric coupling. Energy loss by vibration damping is minimized, and the efficiency can be improved significantly. Experimental results show that the motor characteristics can be optimized for a particular task by choosing the appropriate operating parameters such as exciting voltage, exciting frequency and normal force.

    Full Text Available Objectives: The goal of this project was to develop the first disease-specific instrument for the evaluation of quality of life in chronic pancreatitis. Methods: Focus groups and interview sessions were conducted, with chronic pancreatitis patients, to identify items felt to impact quality of life which were subsequently formatted into a paper-and-pencil instrument. This instrument was used to conduct an online survey by an expert panel of pancreatologists to evaluate its content validity. Finally, the modified instrument was presented to patients during precognitive testing interviews to evaluate its clarity and appropriateness. Results: In total, 10 patients were enrolled in the focus groups and interview sessions where they identified 50 items. Once redundant items were removed, the 40 remaining items were made into a paper-and-pencil instrument referred to as the Pancreatitis Quality of Life Instrument. Through the processes of content validation and precognitive testing, the number of items in the instrument was reduced to 24. Conclusions: This marks the development of the first disease-specific instrument to evaluate quality of life in chronic pancreatitis. It includes unique features not found in generic instruments (economic factors, stigma, and spiritual factors. Although this marks a giant step forward, psychometric evaluation is still needed prior to its clinical use.

    Systemic mastocytosis is a rare heterogeneous myeloproliferative neoplasm characterized by abnormal proliferation and activation of mast cells. We describe a large multicentre series of 460 adult patients with systemic mastocytosis, with a diagnosis based on WHO 2008 criteria, in a "real-life" setting of ten Italian centers with dedicated multidisciplinary programs. We included indolent forms with (n = 255) and without (n = 165) skin lesions, smouldering (n = 20), aggressive (n = 28), associated with other hematological diseases mastocytosis (n = 21) and mast cell leukemia (n = 1). This series was uniquely characterized by a substantial proportion of patients with low burden of neoplastic mast cells; notably, 38% of cases were diagnosed using only minor diagnostic criteria according to WHO 2008 classification, underlying the feasibility of early diagnosis where all diagnostic approaches are made available. This has particular clinical relevance for prevention of anaphylaxis manifestations, that were typically associated with indolent forms. In multivariate analysis, the most important features associated with shortened overall survival were disease subtype and age at diagnosis >60 years. Disease progression was correlated with mastocytosis subtype and thrombocytopenia. As many as 32% of patients with aggressive mastocytosis suffered from early evolution into acute leukemia. Overall, this study provides novel information about diagnostic approaches and current presentation of patients with SM and underlines the importance of networks and specialized centers to facilitate early diagnosis and prevent disease-associated manifestations.

    Full Text Available A research study was conducted (1 to examine the practices employed by US manufacturers to achieve productivity goals and (2 to understand what level of intelligent maintenance technologies and strategies are being incorporated into these practices. This study found that the effectiveness and choice of maintenance strategy were strongly correlated to the size of the manufacturing enterprise; there were large differences in adoption of advanced maintenance practices and diagnostics and prognostics technologies between small and medium-sized enterprises (SMEs. Despite their greater adoption of maintenance practices and technologies, large manufacturing organizations have had only modest success with respect to diagnostics and prognostics and preventive maintenance projects. The varying degrees of success with respect to preventative maintenance programs highlight the opportunity for larger manufacturers to improve their maintenance practices and use of advanced prognostics and health management (PHM technology. The future outlook for manufacturing PHM technology among the manufacturing organizations considered in this study was overwhelmingly positive; many manufacturing organizations have current and planned projects in this area. Given the current modest state of implementation and positive outlook for this technology, gaps, future trends, and roadmaps for manufacturing PHM and maintenance strategy are presented.

    Diabetes (DM) adversely affects prognosis in acute coronary syndromes (ACS). Guidelines promote optimal glycemic management. Cardiac care often occurs in subspecialty units where DM care might not be a primary focus. A questionnaire was circulated to 1183 cardiologists (CARDs), endocrinologists (ENDOs), and internists between February and May 2012 to determine current practices of DM management in patients presenting with ACS. The response rate was 14%. ENDOs differed in perception of DM frequency compared with CARDs and the availability of ENDO consultation within 24 hours and on routinely-ordered tests. Disparity also existed in who was believed to be primarily responsible for in-hospital DM care in ACS: ENDOs perceived they managed glycemia more often than CARDs believed they did. CARDs indicated they most often managed DM after discharge and ENDOs said this occurred much less. However, CARDs reported ENDOs were the best health care professional to follow patients after discharge. ENDOs had higher comfort initiating and titrating oral hypoglycemic agents or various insulin regimens. There was also no difference in these specialists' perceptions that optimizing glucose levels during the acute phase and in the long-term improves cardiovascular outcomes. Significant differences exist in the perception of the magnitude of the problem, acute and longer-term process of care, and comfort initiating new therapies. Nevertheless, all practitioners agree that optimal DM care affects short- and long-term outcomes of patients. Better systems of care are required to optimally manage ACS patients with DM during admission and after discharge from cardiology services.

    Full Text Available Abstract Background During the last 20 years the rate of CS has increased in Sweden as it has in many other countries. The proportion of pregnant women suffering from a high BMI has also increased rapidly during the same time period. It would therefore be of interest to study both how and if these two observations are related to each other. The aim was therefore to study trends in mode of caesarean section (CS and instrumental deliveries among women in three BMI groups over a time span of almost 25 years with special focus on the observed body weight of pregnant women. Method The design is a retrospective cohort study using medical records of consecutively delivered women at two delivery wards in South East Sweden during the years 1978, 1986, 1992, 1997 and 2001. Results No significant time-trends were found for CS and instrumental delivery within each BMI-group for the time period studied. The proportion of women with BMI ≥ 25 delivered by means of CS or instrumental delivery increased quite dramatically from 1978 to 2001 (χ2 test for trend; p Conclusion Overweight and obese pregnant women constitute a rapidly growing proportion of the total number of CS and instrumental deliveries. Planning and allocation of health resources must be adjusted to this fact and its implications.

    Full Text Available Abstract Background Shorter time to treatment is associated with lower mortality in acute coronary syndromes (ACS. A previous (1994 survey showed substantial delays for acute myocardial infarction (AMI in Ireland. The present study compared current practice with 1994 and surveyed acute coronary syndromes as a more complete contemporary evaluation of critical cardiac care than assessing AMI alone. Methods Following ethics committee approval, all centres (N = 39 admitting acute cardiac patients to intensive/coronary care unit provided information on 1365 episodes. A cross-sectional survey design was employed. Results Since 1994, median hospital arrival to thrombolysis time was reduced by 41% (76 to 45 minutes. Thrombolysis was delivered more often in the emergency department in 2003 (48% vs 2%. Thrombolysis when delivered in the emergency department was achieved faster than thrombolysis delivered in intensive/coronary care (35 mins v 60 mins; z = 5.62, p Conclusions Substantial improvements in time to thrombolysis have occurred since 1994, probably relating to treatment provision in emergency departments. Patient delay pre-hospital is still the principal impediment to effective treatment of ACS. A recent change of definition of AMI may have precluded an exact comparison between 1994 and 2003 data.

    Concordance studies indicate the degree to which instruments measure the same or similar constructs or something different. The aims of this study were to identify the factor structure of the Deamonte Driver Survey and determine the relationship between the Deamonte Driver (a measure of social class stereotyping), the Defining Issues Test 2 (DIT2; a measure of ethical sensitivity), the Color-Blind Racial Attitudes Scale (CoBRAS; a measure of racial stereotyping), and the Knowledge, Efficacy, and Practices Instrument (KEPI; a measure of cultural competence). The results showed a three-factor solution for the Deamonte Driver Survey and significant relationships between CoBRAS and DIT2 subscales and between CoBRAS and Deamonte Driver subscales. Significant relationships between the measures and exploratory variables, underrepresented minority status, age, citizenship, marital status, political stance, English as a first language, and gender were found. The lack of a significant relationship between the KEPI and Deamonte Driver, DIT2, or CoBRAS subscales suggests that the KEPI is measuring a unique construct. These findings showed how these scales contributed to the assessment of cultural competence among dental students and faculty.

    In order to extend the current suite of instruments offered in the Observatorio Astrofísico Guillermo Haro (OAGH) in Cananea, Mexico (INAOE), and to explore a second-generation instrument for the future 6.5 m Telescopio San Pedro Martir (TSPM), we propose a prototype instrument that will provide un-biased wide-field (few arcmin) spectroscopic information, with the flexibility of operating at different spectral resolutions (R˜1-104), with a spatial resolution limited by seeing, and therefore to be used in a wide range of astronomical problems. This instrument will make use of the Fourier Transform Spectroscopy technique, which has been proved to be feasible in the optical wavelength range. Here we give the basic technical description of a Fourier transform spectrograph, as well as the technical advantages and weaknesses, and the science cases in which this instrument can be implemented.

    Aims: Detailed data on patients admitted for acute myocardial infarction (AMI) on a European-wide basis are lacking. The Euro Heart Survey 2009 Snapshot was designed to assess characteristics, management, and hospital outcomes of AMI patients throughout European Society of Cardiology (ESC) member countries in a contemporary ‘real-world’ setting, using a methodology designed to improve the representativeness of the survey. Methods: Member countries of the ESC were invited to participate in a 1-week survey of all patients admitted for documented AMI in December 2009. Data on baseline characteristics, type of AMI, management, and complications were recorded using a dedicated electronic form. In addition, we used data collected during the same time period in national registries in Sweden, England, and Wales. Data were centralized at the European Heart House. Results: Overall, 4236 patients (mean age 66±13 years; 31% women) were included in the study in 47 countries. Sixty per cent of patients had ST-segment elevation myocardial infarction, with 50% having primary percutaneous coronary intervention and 21% fibrinolysis. Aspirin and thienopyridines were used in >90%. Unfractionated and low-molecular-weight heparins were the most commonly used anticoagulants. Statins, beta-blockers, and angiotensin-converting enzyme inhibitors were used in >80% of the patients. In-hospital mortality was 6.2%. Regional differences were observed, both in terms of population characteristics, management, and outcomes. Conclusions: In-hospital mortality of patients admitted for AMI in Europe is low. Although regional variations exist in their presentation and management, differences are limited and have only moderate impact on early outcomes. PMID:24338295

    This interim report is designed to show the present status of the Geological Survey's information and the parts of a comprehensive program necessary to improve our information about the raw material resources of uranium and thorium. Rarely in geologic work has it been necessary. to determine so completely a nation's resources of useful minerals in so brief a span of time. Ordinarily, information on mineral resources Is accumulated during a long period of years. However, uranium and thorium were suddenly thrust from a position of subsidiary economic interest into one of great strategic importance. Information concerning their occurrence must, therefore, be obtained as rapidly as reliable methods of investigation will permit. Accordingly the program must be at once comprehensive and carried out over an area more extensive than is usual in the search for and appraisal of most other mineral resources.

A subset of parents (n = 156 completed the HES a second time to determine test-retest reliability. Finally, 41 parent dyads living in the same home (n = 41 completed the survey to determine inter-rater reliability. Initial psychometric analyses were completed to trim items from the measure based on lack of variability in responses, moderate or higher item to scale correlation, or contribution to strong internal consistency. Inter-rater and test-retest reliability were completed using intraclass correlation coefficients. Validity was assessed using Pearson correlations between the HES scores and child and parent nutrition and PA. Results Eight items were removed and acceptable internal consistency was documented for all scales (α = .66–84 with the exception of the F&V accessibility. The F&V accessibility was reduced to a single item because the other two items did not meet reliability standards. Test-retest reliability was high (r > .75 for all scales. Inter-rater reliability varied across scales (r = .22–.89. PA accessibility, parent role modelling, and parental policies were all related significantly to child (r = .14–.21 and parent (r = .15–.31 PA. Similarly, availability of F&V and SS, parental role modelling, and parental policies were related to child (r

    Full Text Available Abstract Background Many epidemiological and public health surveys report increasing difficulty obtaining high participation rates. We conducted a pilot follow-up study to determine whether a mailed or telephone survey would better facilitate data collection in a subset of respondents to an earlier telephone survey conducted as part of the National Birth Defects Prevention Study. Methods We randomly assigned 392 eligible mothers to receive a self-administered, mailed questionnaire (MQ or a computer-assisted telephone interview (CATI using similar recruitment protocols. If mothers gave permission to contact the fathers, fathers were recruited to complete the same instrument (MQ or CATI as mothers. Results Mothers contacted for the MQ, within all demographic strata examined, were more likely to participate than those contacted for the CATI (86.6% vs. 70.6%. The median response time for mothers completing the MQ was 17 days, compared to 29 days for mothers completing the CATI. Mothers completing the MQ also required fewer reminder calls or letters to finish participation versus those assigned to the CATI (median 3 versus 6, though they were less likely to give permission to contact the father (75.0% vs. 85.8%. Fathers contacted for the MQ, however, had higher participation compared to fathers contacted for the CATI (85.2% vs. 54.5%. Fathers recruited to the MQ also had a shorter response time (median 17 days and required fewer reminder calls and letters (median 3 reminders than those completing the CATI (medians 28 days and 6 reminders. Conclusions We concluded that offering a MQ substantially improved participation rates and reduced recruitment effort compared to a CATI in this study. While a CATI has the advantage of being able to clarify answers to complex questions or eligibility requirements, our experience suggests that a MQ might be a good survey option for some studies.

    Abstract Background  Growing recognition of the role of citizens and patients in health and health care has placed a spotlight on health literacy and patient education. Objective  To identify specific competencies for health in definitions of health literacy and patient‐centred concepts and empirically test their dimensionality in the general population. Methods  A thorough review of the literature on health literacy, self‐management, patient empowerment, patient education and shared decision making revealed considerable conceptual overlap as competencies for health and identified a corpus of 30 generic competencies for health. A questionnaire containing 127 items covering the 30 competencies was fielded as a telephone interview in German, French and Italian among 1255 respondents randomly selected from the resident population in Switzerland. Findings  Analyses with the software MPlus to model items with mixed response categories showed that the items do not load onto a single factor. Multifactorial models with good fit could be erected for each of five dimensions defined a priori and their corresponding competencies: information and knowledge (four competencies, 17 items), general cognitive skills (four competencies, 17 items), social roles (two competencies, seven items), medical management (four competencies, 27 items) and healthy lifestyle (two competencies, six items). Multiple indicators and multiple causes models identified problematic differential item functioning for only six items belonging to two competencies. Conclusions  The psychometric analyses of this instrument support broader conceptualization of health literacy not as a single competence but rather as a package of competencies for health.

    2012-01-01

    Hohashi's Concentric Sphere Family Environment Model (CSFEM; Hohashi & Honda, 2011) is a newly proposed family nursing theory for holistically understanding the family environment that acts on family well-being. The purpose of this article is to develop and psychometrically test the Japanese version of the Survey of Family Environment (SFE-J), grounded in the CSFEM, for measuring family's perceived family functioning and family's perceived needs for family support. The SFE-J is a 30-item self-administered instrument that assesses five domains (suprasystem, macrosystem, microsystem, family internal environment system, and chronosystem) and has been subjected to rigorous reliability and validity investigations among paired partners in child-rearing families (N of family = 1,990). Internal consistency reliability was high as measured by Cronbach's alpha coefficients. Temporal stability over a 2-week interval was supported by high (substantial or perfect) and significant intraclass correlation coefficients. The total score for the SFE-J was significantly correlated with the Japanese version of the Feetham Family Functioning Survey (FFFS-J), indicating an acceptable concurrent validity. Construct validity was supported by a confirmatory factor analysis that evaluated the five-factor structure to measure the concept of CSFEM. Results also demonstrate that the SFE-J family functioning scores show no significant differences between paired partners. The SFE-J is a reliable and valid instrument to assess not only intrafamily functioning but also interfamily functioning and, by identifying items/domains with high requirements for family support, serves to facilitate the providing of appropriate support to families.

    Developing competence in clinical skills is important if graduates are to provide entry-level care but it is dependent on having had sufficient hands-on practice. Clinical skills laboratories provide opportunities for students to learn on simulators and models in a safe environment and to supplement training with animals. Interest in facilities for developing veterinary clinical skills has increased in recent years as many veterinary colleges face challenges in training their students with traditional methods alone. For the present study, we designed a survey to gather information from established veterinary clinical skills laboratories with the aim of assisting others considering opening or expanding their own facility. Data were collated from 16 veterinary colleges in North America and Europe about the uses of their laboratory, the building and associated facilities, and the staffing, budgets, equipment, and supporting learning resources. The findings indicated that having a dedicated veterinary clinical skills laboratory is a relatively new initiative and that colleges have adopted a range of approaches to implementing and running the laboratory, teaching, and assessments. Major strengths were the motivation and positive characteristics of the staff involved, providing open access and supporting self-directed learning. However, respondents widely recognized the increasing demands placed on the facility to provide more space, equipment, and staff. There is no doubt that veterinary clinical skills laboratories are on the increase and provide opportunities to enhance student learning, complement traditional training, and benefit animal welfare.

    The Single Particles, Clusters and Biomolecules (SPB) instrument at the European XFEL is located behind the SASE1 undulator, and aims to support imaging and structure determination of biological specimen between about 0.1 micrometer and 1 micrometer size. The instrument is designed to work at photon energies from 3 keV up to 16 keV. This wide operation range is a cause for challenges to the focusing optics. In particular, a long propagation distance of about 900 m between x-ray source and sample leads to a large lateral photon beam size at the optics. The beam divergence is the most important parameter for the optical system, and is largest for the lowest photon energies and for the shortest pulse duration (corresponding to the lowest charge). Due to the large divergence of nominal X-ray pulses with duration shorter than 10 fs, one suffers diffraction from mirror aperture, leading to a 100-fold decrease in fluence at photon energies around 4 keV, which are ideal for imaging of single biomolecules. The nominal...

    Full Text Available Although there are numerous threats to ecosystems and the resultant ecosystem services, alien and invasive plants (AIP have been identified as being one of the major causes of ecosystem destruction. In addressing the threat of alien and invasive plants through the use of various mechanisms, the regulatory framework imposed by legislation is key in ensuring that that controlling AIPs does in fact not do more harm than good. One such control mechanism, which has the potential to do wonders or wreak havoc if not adroitly implemented, is that of using biological control agents. This contribution provides a brief overview on the three main regulatory instruments used to control biological control agents in South Africa, namely the Conservation of Agricultural Resources Act 43 of 1983, the Agricultural Pests Act 36 of 1983 and the National Environmental Management: Biodiversity Act 10 of 2004. It also considers possible future developments on the regulation of biological control agents.

We developed the 16-item Patient-Reported Arthralgia Inventory (PRAI to measure arthralgia severity in 16 joints, in the context of a longitudinal cohort study to assess aromatase inhibitor-associated arthralgia in breast cancer survivors and arthralgia in postmenopausal women without breast cancer. We sought to evaluate the reliability and validity of the PRAI instrument in these populations, as well as to examine the relationship of patient-reported morning stiffness and arthralgia. Methods: We administered the PRAI on paper in 294 women (94 initiating aromatase inhibitor therapy and 200 postmenopausal women without breast cancer at weeks 0, 2, 4, 6, 8, 12, 16, and 52, as well as once in 36 women who had taken but were no longer taking aromatase inhibitor therapy. Results: Cronbach's alpha was 0.9 for internal consistency of the PRAI. Intraclass correlation coefficients of test-retest reliability were in the range of 0.87–0.96 over repeated PRAI administrations; arthralgia severity was higher in the non-cancer group at baseline than at subsequent assessments. Women with joint comorbidities tended to have higher PRAI scores than those without (estimated difference in mean scores: -0.3, 95% confidence interval [CI] -0.5, -0.2; P<0.001. The PRAI was

    Four radionuclides have been identified as being sufficiently volatile in the reprocessing of nuclear fuel that their gaseous release needs to be controlled to meet regulatory requirements (Jubin et al. 2011, 2012). These radionuclides are 3H, 14C, 85Kr, and 129I. Of these, 129I has the longest half-life and potentially high biological impact. Accordingly, control of the release of 129I is most critical with respect to the regulations for the release of radioactive material in stack emissions. It is estimated that current EPA regulations (EPA 2010) would require any reprocessing plant in the United States to limit 129I release to less than 0.05 Ci/MTIHM for a typical fuel burnup of 55 gigawatt days per metric tonne (GWd/t) (Jubin 2011). The study of inorganic iodide in off-gas systems has been almost exclusively limited to I2 and the focus of organic iodide studies has been CH3I. In this document, we provide the results of an examination of publically available literature that is relevant to the presence and sources of both inorganic and organic iodine-bearing species in reprocessing plants. We especially focus on those that have the potential to be poorly sequestered with traditional capture methodologies. Based on the results of the literature survey and some limited thermodynamic modeling, the inorganic iodine species hypoiodous acid (HOI) and iodine monochloride (ICl) were identified as potentially low-sorbing iodine species that could present in off-gas systems. Organic species of interest included both short chain alkyl iodides such as methyl iodide (CH3I) and longer alkyl iodides up to iodododecane (C10H21I). It was found that fuel dissolution may provide conditions conducive to HOI formation and has been shown to result in volatile long-chain alkyl iodides, though these may not volatilize until later in the reprocessing sequence. Solvent extraction processes were found to be significant sources of various organic iodine-bearing species; formation of these

The instrument is designed to work at photon energies from 3 keV up to 16 keV. This wide operation range is a cause for challenges to the focusing optics. In particular, a long propagation distance of about 900 m between X-ray source and sample leads to a large lateral photon beam size at the optics. The beam divergence is the most important parameter for the optical system, and is largest for the lowest photon energies and for the shortest pulse duration (corresponding to the lowest charge). Due to the large divergence of nominal X-ray pulses with duration shorter than 10 fs, one suffers diffraction from mirror aperture, leading to a 100-fold decrease in fluence at photon energies around 4 keV, which are ideal for imaging of single biomolecules. The nominal SASE1 output power is about 50 GW. This is very far from the level required for single biomolecule imaging, even assuming perfect beamline and focusing efficiency. Here we demonstrate that the parameters of the accelerator complex and of the SASE1 undulator offer an opportunity to optimize the SPB beamline for single biomolecule imaging with minimal additional costs and time. Start to end simulations from the electron injector at the beginning of the accelerator complex up to the generation of diffraction data indicate that one can achieve diffraction without diffraction with about 0.5 photons per Shannon pixel at near-atomic resolution with 10{sup 13} photons in a 4 fs pulse at 4 keV photon energy and in a 100 nm focus, corresponding to a fluence of 10{sup 23}ph/cm{sup 2}. This result is exemplified using the RNA Pol II molecule as a case study.

    The objectives of this study were (1) to clarify changes in social concern in intergenerational programs and (2) to determine the current state of and issues affecting intergenerational programs. Articles including the words "intergenerational programs" were selected from 3 major Japanese newspapers (Asahi Shimbun, Yomiuri Shimbun, and Mainichi Shimbun) using an online database (399 articles). Content analysis was conducted to check changes in the number and content of articles. A total of 56 cases of intergenerational programs were selected, and a questionnaire survey was conducted with the responsible organization. The problems were classified using cluster analysis. Content analysis revealed that the number of articles relating to this topic increased towards the end of the 1990s, which corresponds with a change in social policy. The questionnaire survey revealed that most of the intergenerational programs were either annual or periodic activities. Furthermore, it was shown that the 4 main issues facing current intergenerational programs were the intergenerational gap, operating problems, activity selection, and lack of participants. In summary, social concern regarding the intergenerational programs has increased. However, most intergenerational programs were infrequent and quite time-intensive. Furthermore, the 4 issues mentioned above must be addressed in order to create programs that have wide-ranging benefits for each community. Resolving the problem of compartmentalized administration and appointing local coordinators is necessary to solve these problems.

    Context: The ESO Public Survey "VISTA Variables in the V\\'ia L\\'actea" (VVV) provides deep multi-epoch infrared observations for an unprecedented 562 sq. degrees of the Galactic bulge, and adjacent regions of the disk. Aims: The VVV observations will foster the construction of a sample of Galactic star clusters with reliable and homogeneously derived physical parameters (e.g., age, distance, and mass, etc.). In this first paper in a series, the methodology employed to establish cluster parameters for the envisioned database are elaborated upon by analyzing a subsample of 4 known young open clusters: Danks 1, Danks 2, RCW 79, and DBS 132. The analysis offers a first glimpse of the information that can be gleaned for the final cluster database from the VVV observations. Methods: Wide-field, deep JHKs VVV observations, combined with new infrared spectroscopy, are employed to constrain fundamental parameters for a subset of clusters. Results: Results inferred from the deep near-infrared photometry which features ...

    Aging is unavoidable and natural phenomenon of life. Modern gerontologists are realizing the fact that aging is a disease, which Ayurveda had accepted as natural disease since long. Rate of aging is determined by one's biological, social, lifestyle, and psychological conditions and adversity of which leads to accelerated form of aging (Akalaja jara or premature aging). The aim of this study is to identify potential factors that may accelerate aging in the context of dietry factors, lifestyle and mental makeup. The 120 diagnosed subjects of premature-ageing of 30-60 years were randomly selected in the survey study. Premature ageing was common among females (75.83%), in 30-40 age group (70%), 86.67% were married, had secondary level of education (36.66%), house-views (61.67%), belongs top middle class (58.33%) and engaged in occupations that dominating physical labour (88.33%). The maximum patients are constipated (60%), had mandagni (80%), vata-kapha prakriti (48.33%), rajasika prakriti (58.33%), madhyama vyayama shakti (73.33%), and madhyama jarana shakti (85.83%). Collectively, 43.33% patients were above normal BMI. The more patients had anushna (38.33%) and vishamasana dietary pattern (25.83%), consumed Lavana (88.33%) and Amla rasa (78.33%) in excess on regular basis. Some patients had addicted to tobacco (11.67%) and beetle chewing (5.83%). The maximum patients had no any exercise (79.17%) and specific hobby (79.17%) in their leisure times. Analyzing Hamilton Anxiety and Depression Rating Scales revealed that 39.80%, 37.86%, 33.98%, 24.27% and 18.44% patients had insomnia, depression, tension, GIT symptoms and anxious mood respectively. These data suggest that certain social, dietary and lifestyle factors contribute towards accelerated ageing among young individuals.

    Full Text Available Abstract Background Leptospirosis is a potentially fatal disease which can cause multi-organ dysfunction. It can rarely present as acute pancreatitis. This is the first ever report of leptospirosis presenting with acute pancreatitis and myocarditis followed by diffuse pulmonary hemorrhages to the best of our knowledge. Case presentation A 15-year-old South Asian boy presented with high grade fever, epigastric discomfort and was anicteric on admission. He developed tachycardia, transient hypotension, changes of electro-cardiogram and positive troponin I suggestive of myocarditis. Acute pancreatitis was diagnosed with 12 fold high serum amylase and with the evidence of computerized tomography. Then he developed diffuse pulmonary hemorrhages and later acute renal failure. Leptospirosis was confirmed by positive leptospira IgM, negative IgG and strongly positive Microscopic Agglutination Test. Other possible infective and autoimmune causes were excluded. Patient recovered completely with antibiotics and the supportive care. Conclusion This case illustrates diagnostic difficulties especially in resource poor settings where leptospirosis is common. Additionally it highlights the fact that leptospirosis should be considered in patients presenting with pancreatitis which can be complicated with myocarditis and diffuse pulmonary hemorrhages. We hypothesize that Toll like receptors may play a role in such systemic involvement.

    European cancer survival rates vary widely. System factors, including whether or not primary care physicians (PCPs) are gatekeepers, may account for some of these differences. This study explores where patients who may have cancer are likely to present for medical care in different European countries, and how probability of presentation to a primary care clinician correlates with cancer survival rates. Seventy-eight PCPs in a range of European countries assessed four vignettes representing patients who might have cancer, and consensus groups agreed how likely those patients were to present to different clinicians in their own countries. These data were compared with national cancer survival rates. A total of 14 countries. Consensus groups of PCPs. Probability of initial presentation to a PCP for four clinical vignettes. There was no significant correlation between overall national 1-year relative cancer survival rates and the probability of initial presentation to a PCP (r  = -0.16, 95% CI -0.39 to 0.08). Within that there was large variation depending on the type of cancer, with a significantly poorer lung cancer survival in countries where patients were more likely to initially consult a PCP (lung r = -0.57, 95% CI -0.83 to -0.12; ovary: r = -0.13, 95% CI -0.57 to 0.38; breast r = 0.14, 95% CI -0.36 to 0.58; bowel: r = 0.20, 95% CI -0.31 to 0.62). There were wide variations in the degree of gatekeeping between countries, with no simple binary model as to whether or not a country has a "PCP-as-gatekeeper" system. While there was case-by-case variation, there was no overall evidence of a link between a higher probability of initial consultation with a PCP and poorer cancer survival. KEY POINTS European cancer survival rates vary widely, and health system factors may account for some of these differences. The data from 14 European countries show a wide variation in the probability of initial presentation to a PCP. The degree to

    Oral and poster presentations at congresses are essential to spread scientific knowledge among the medical community. Many scientific societies have analyzed the quality of papers presented at their meetings but no information on abstracts' evaluation has been presented in Public Health field. This study aims to examine the quality of abstracts presented at annual meetings of Italian Public Health Society (SItI) in the period 2005-2010 through a validated checklist grid, evaluating eight dimensions: Inherency, Structure, Originality, Objectives, Study design, Sources, Results, Conclusions. Each item was scored from 0 to 3 points (max score: 24) and we used the average score in our study (15) as threshold of good quality. A multivariate analysis was performed in order to investigate predictors of score of abstracts presented. A total of 4,399 abstracts (1,172 oral communications, 3,227 posters) was examined. Around 60% were submitted by Universities and around 40% were from Central Italy. The highest quality was found in the fields of Vaccines (average score 18.9), Infectious Diseases (18) and in abstracts submitted by Universities (16.4). Predictors of lower quality identified were geographical area and affiliation (p= 0.002). Abstracts containing well-written Results, Conclusions and Objectives (3 points) were more likely to be of high quality(OR=55.6, OR=41.9, and OR=157.4; p>0.001) CONCLUSIONS: This is the first European study evaluating the quality of abstracts in the public health field. A reliable evaluation tool is fundamental to offer a transparent methodology of assessment and to improve the quality of research.

    WFIRST-AFTA is the NASA's highest ranked astrophysics mission for the next decade that was identified in the New World, New Horizon survey. The mission scientific drivers correspond to some of the deep questions identified in the Canadian LRP2010, and are also of great interest for the Canadian scientists. Given that there is also a great interest in having an international collaboration in this mission, the Canadian Space Agency awarded two contracts to study a Canadian participation in the mission, one related to each instrument. This paper presents a summary of the technical contributions that were considered for a Canadian contribution to the coronagraph and wide field instruments.

    2013-01-01

    High intraoral pressure generated when playing some wind instruments has been linked to a variety of health issues. Prior research has focused on Western classical instruments, but no work has been published on ethnic wind instruments. This study measured intraoral pressure when playing six classes of ethnic wind instruments (N = 149): Native American flutes (n = 71) and smaller samples of ethnic duct flutes, reed instruments, reedpipes, overtone whistles, and overtone flutes. Results are presented in the context of a survey of prior studies, providing a composite view of the intraoral pressure requirements of a broad range of wind instruments. Mean intraoral pressure was 8.37 mBar across all ethnic wind instruments and 5.21 +/- 2.16 mBar for Native American flutes. The range of pressure in Native American flutes closely matches pressure reported in other studies for normal speech, and the maximum intraoral pressure, 20.55 mBar, is below the highest subglottal pressure reported in other studies during singing...

    Some active galactic nuclei (AGN) are surrounded by extended emission-line regions (EELRs), which trace both the illumination pattern of escaping radiation and its history over the light-travel time from the AGN to the gas. From a new set of such EELRs, we present evidence that the AGN in many Seyfert galaxies undergo luminous episodes 20,000-200,000 years in duration. Motivated by the discovery of the spectacular nebula known as Hanny's Voorwerp, ionized by a powerful AGN which has apparently faded dramatically within ~ 100,000 years, Galaxy Zoo volunteers have carried out both targeted and serendipitous searches for similar emission-line clouds around low-redshift galaxies.We present the resulting list of candidates and describe spectroscopy identifying 19 galaxies with AGN-ionized regions at projected radii > 10 kpc. This search recovered known EELRs and identified additional previously unknown cases, one with detected emission to r = 37 kpc. At least 14/19 are in interacting or merging systems; tidal tail...

    In this paper, which is the first in a series of papers associated with cataclysmic variables and related objects, we introduce the CATUABA code, a numerical machinery written for analysis of the MOCCA simulations, and show some first results by investigating the present-day population of cataclysmic variables in globular clusters. Emphasis was given on their properties and the observational selection effects when observing and detecting them. In this work we analysed in this work six models, including three with Kroupa distributions of the initial binaries. We found that for models with Kroupa initial distributions, considering the standard value of the efficiency of the common envelope phase adopted in BSE, no single cataclysmic variable was formed only via binary stellar evolution, i. e., in order to form them, strong dynamical interactions have to take place. We show and explain why this is inconsistent with observational and theoretical results. Our results indicate that the population of cataclysmic var...

    Induced abortion on demand or for socio-economic indications is illegal in Papua New Guinea under the 1974 Criminal Code. Nevertheless, the procedure is known to be widely practised. This prospective study examines the demographic and medical features of women presenting with complications of induced abortion to Goroka Hospital in a 6-month period. It was noted that abortion was most commonly induced using the synthetic prostaglandin analogue misoprostol. Although illegal induced abortion cannot be condoned, it appears that misoprostol, much safer in this context than mechanical or traditional herbal methods, is now being widely used for the purpose of induced abortion in Papua New Guinea, as it is in other developing countries.

    Surveys are a valuable research tool for studying the knowledge, attitudes, and behavior of a study population. This article explores quantitative analyses of written questionnaires as instruments for survey research. Obtaining accurate and precise information from a survey requires minimizing the possibility of bias from inappropriate sampling or a flawed survey instrument, and this article describes strategies to minimize sampling bias by increasing response rates, comparing responders to nonresponders, and identifying the appropriate sampling population. It is crucial that the survey instrument be valid, meaning that it actually measures what the investigator intends it to measure. In developing a valid survey instrument, it can be useful to adapt survey instruments that were developed by other researchers and to conduct extensive pilot-testing of your survey instrument.

  9. Can postponement of an adverse outcome be used to present risk reductions to a lay audience? A population survey

    2007-03-01

    Full Text Available Abstract Background For shared decision making doctors need to communicate the effectiveness of therapies such that patients can understand it and discriminate between small and large effects. Previous research indicates that patients have difficulties in understanding risk measures. This study aimed to test the hypothesis that lay people may be able to discriminate between therapies when their effectiveness is expressed in terms of postponement of an adverse disease event. Methods In 2004 a random sample of 1,367 non-institutionalized Danes aged 40+ was interviewed in person. The participants were asked for demographic information and asked to consider a hypothetical preventive drug treatment. The respondents were randomized to the magnitude of treatment effectiveness (heart attack postponement of 1 month, 6 months, 12 months, 2 years, 4 years and 8 years and subsequently asked whether they would take such a therapy. They were also asked whether they had hypercholesterolemia or had experienced a heart attack. Results In total 58% of the respondents consented to the hypothetical treatment. The proportions accepting treatment were 39%, 52%, 56%, 64%, 67% and 73% when postponement was 1 month, 6 months, 12 months, 2 years, 4 years and 8 years respectively. Participants who thought that the effectiveness information was difficult to understand, were less likely to consent to therapy (p = 0.004. Conclusion Lay people can discriminate between levels of treatment effectiveness when they are presented in terms of postponement of an adverse event. The results indicate that such postponement is a comprehensible measure of effectiveness.

    Directory of Open Access Journals (Sweden)

    Bryan Mitchell Evans

    2013-07-01

    Full Text Available Various analysts have raised concerns respecting declining research, evaluation and analytical capacities within public services. Typically, the decline is attributed to reforms associated with neoliberal restructuring of the state and its concomitant managerial expression in New Public Management (NPM.  This has given rise to a conceptual shift now commonly captured as a movement from ‘government’ to ‘governance’. Policy advising from a new governance perspective entails an image of a more distributed policy advisory system where a plurality of actors, including non-state actors, engages with government in deliberating policy interventions to address collective problems.The original research presented here suggests that those responsible for policy work across four policy communities in the three Canadian provinces surveyed differ in terms of their capacities, depth of commitment to a specific policy file/field, roles and functions, as well as perceptions of the policy work that they undertake. Over the past several years, a number of primarily quantitative analyses examining the processes, tools and perspectives of Canadian federal and provincial government policy analysts have been published.  Consequently, a significant knowledge-base has been acquired respecting what government policy analysts do and their attitudes toward their work but very little is known about external interactions with non-governmental organizations (NGOs.

    TAIPAN will conduct a stellar and galaxy survey of the Southern sky. The TAIPAN positioner is being developed as a prototype for the MANIFEST instrument on the GMT. The design for TAIPAN incorporates 150 optical fibres (with an upgrade path to 300) situated within independently controlled robotic positioners known as Starbugs. Starbugs allow precise parallel positioning of individual fibres, thus significantly reducing instrument configuration time and increasing the amount of observing time. Presented is an engineering overview of the UKST upgrade of the completely new Instrument Spider Assembly utilized to support the Starbug Fibre Positioning Robot and current status of the Starbug itself.

    To search photometric variability in chemically peculiar A type stars in the northern hemisphere. High-speed photometric observations of Ap and Am star candidates have been carried out from ARIES (Manora Peak, Nainital) using a three-channel fast photometer attached to the ARIES 104-cm Sampurnanand telescope. This paper presents three new variables: HD 113878, HD 118660 and HD 207561. During the time span of the survey (1999 December to 2004 January) pulsations of the $\\delta$ Sct type were also found for the two evolved Am stars HD 102480 and HD 98851, as reported in Joshi et al. (2002, 2003). Additionally, we present 140 null results of the survey for this time span. The star HD 113878 pulsates with a period of 2.31 hr, which is typical of $\\delta$ Sct stars. HD 118660 exhibits multi-periodic variability with a prominent period of nearly 1 hr. These periods need to be investigated and make HD 118660 a particularly interesting target for further observations. For HD 207561, a star classified as Am, a probabl...

    The present survey aimed to clarify the prevalence of gastroesophageal reflux disease (GERD) and functional dyspepsia (FD) in patients presenting with epigastric symptoms in Japan based on the Montreal definition and the Rome III criteria, respectively, and to determine the degree of overlap between the two disease entities and the validity of using these Western-developed diagnostic criteria in Japan. Patients presenting with epigastric symptoms for whom the first upper gastrointestinal endoscopy was scheduled from April through August 2007 at 55 institutions were asked to complete a questionnaire to ascertain the type, frequency, and severity of epigastric symptoms. The prevalence of esophageal mucosal damage was also determined from endoscopic findings. A total of 1,076 patients were included in the analysis population. There was a high degree of coincidence for all symptoms, with the mean number of symptoms per patient of 2.8. With strict application of the Montreal and Rome III definitions, symptomatic GERD accounted for 15.6% (168 patients), whereas FD accounted for 10.3% (111 patients), and the overlap between GERD and FD symptoms was less than 10%. However, when frequency and severity alone were considered in more broadly defined criteria, the overlap between GERD and FD symptoms was 30-40%. A highly specific disease classification is possible when the Montreal definition and the Rome III criteria are strictly applied. On the other hand, the present survey highlighted a problem with the criteria whereby a definitive diagnosis could not be made in a substantial number of patients. This problem will require further research.

    Woźniak, Przemysław

    Robotic telescopes are revolutionizing the way astronomers collect their dataand conduct sky surveys. This chapter begins with a discussion of principles thatguide the process of designing, constructing, and operating telescopes andobservatories that offer a varying degree of automation, from instruments remotelycontrolled by observers to fully autonomous systems requiring no humansupervision during their normal operations. Emphasis is placed on designtrade-offs involved in building end-to-end systems intended for a wide range ofscience applications. The second part of the chapter contains descriptions ofseveral projects and instruments, both existing and currently under development.It is an attempt to provide a representative selection of actual systems thatillustrates state of the art in technology, as well as important ideas and milestonesin the development of the field. The list of presented instruments spans the fullrange in size starting from small all-sky monitors, through midrange robotic andsurvey telescopes, and finishing with large robotic instruments and surveys.Explosive growth of telescope networking is enabling entirely new modesof interaction between the survey and follow-up observing. Increasingimportance of standardized communication protocols and software is stressed.These developments are driven by the fusion of robotic telescope hardware,massive storage and databases, real-time knowledge extraction, and datacross-correlation on a global scale. The chapter concludes with examplesof major science results enabled by these new technologies and futureprospects.

    The development of specialized units dedicated to life-threatening management has demonstrated to improve the prognosis of patients requiring such treatments. However, apart those focused on trauma and stroke, networks are still lacking in France. Despite, the implementation of standardisation of practices and guidelines, particularly in prehospital care, in-hospital clinical practices at admission remain heterogenous. This survey aimed to assess the structural and human organization of teaching hospitals in France concerning the primary in-hospital care for critically ill patients. A questionnaire of 45 items was sent by e-mail to 32 teaching hospitals between January and March 2013. It included information related to the description of the emergency department, of ICUs, and both structural and human organizations for primary in-hospital care of life-threatening patients. Seventy-five percent of teaching hospitals answered to the survey. Seven hundred to 1400 patients were admitted to emergency units per week and among them 10 to 20 were admitted for critically ill conditions. These latter were addressed in a specialized room of the emergency unit (Service d'admission des urgences vitales [SAUV]) in 40% of hospitals and in specialized room in ICU in 18% of cases. Intensivists were involved in 50% of hospitals, emergency physicians in 26% and it was mixed in 24% of hospitals. This survey is the first to assess the in-hospital organization of primary care for instable and life-threatening patients in France. Our results confirmed the extreme heterogeneity of structural and human organizations for primary in-hospital care of patients presenting at least one organ failure. Thus, a consensus is probably needed to homogenize and improve our practices. Copyright © 2015 Société française d’anesthésie et de réanimation (Sfar). Published by Elsevier Masson SAS.

    2009-05-27

    NERSC recently undertook a project to access and analyze Secure Shell (SSH) related data. This includes authentication data such as user names and key fingerprints, interactive session data such as keystrokes and responses, and information about noninteractive sessions such as commands executed and files transferred. Historically, this data has been inaccessible with traditional network monitoring techniques, but with a modification to the SSH daemon, this data can be passed directly to intrusion detection systems for analysis. The instrumented version of SSH is now running on all NERSC production systems. This paper describes the project, details about how SSH was instrumented, and the initial results of putting this in production.

    A growing body of evidence indicates that the star formation rate per unit stellar mass (sSFR) decreases with increasing mass in normal "main-sequence" star forming galaxies. Many processes have been advocated as responsible for such a trend (also known as mass quenching), e.g., feedback from active galactic nuclei (AGNs), and the formation of classical bulges. We determine a refined star formation versus stellar mass relation in the local Universe. To this aim we use the Halpha narrow-band imaging follow-up survey (Halpha3) of field galaxies selected from the HI Arecibo Legacy Fast ALFA Survey (ALFALFA) in the Coma and Local superclusters. By complementing this local determination with high-redshift measurements from the literature, we reconstruct the star formation history of main-sequence galaxies as a function of stellar mass from the present epoch up to z=3. In agreement with previous studies, our analysis shows that quenching mechanisms occur above a threshold stellar mass M_knee that evolves with redsh...

    Full Text Available Settings and Design: This study documents a survey of final-year ophthalmology postgraduates on the subject of their surgical training and their future plans after residency. Purpose: This survey aimed to answer the question, "What is the present status of surgical training in ophthalmic training centers?" by obtaining information from students about (1 various methods used in surgical training (2 numbers and types of surgeries performed by them in the training centers (3 their plans after residency. Materials and Methods: A questionnaire containing 21 questions was distributed to 155 students attending an intensive 4-day teaching program. The questions related to orientation training, wet lab training, facilities for training, free surgical camps and detailed information about numbers and types of surgeries observed and performed. Completed questionnaires were collected, and responses analyzed. Results: One hundred and seven completed responses were analyzed. The majority had not received formal orientation training. More than half had undergone wet lab training. Most residents performed their first ophthalmic surgery during the 1 st year of residency and went to the operation theatre multiple times a week. Most of the students planned to undergo further training after residency. More than half of the students found their surgical training to be fair or satisfactory. Conclusions: The number and frequency of ophthalmic surgeries done by residents appear satisfactory, but further efforts from trainers on enhancing the quality and range of surgical training would benefit students and improve their satisfaction.

    With the aim to achieve a more equitable budgetary allocation to nursing homes, an instrument for the evaluation of the patients' dependency has been developed and tested in 55 institutions, for a total of about 23000 observations. Statistical analyses show that the internal validity of the gathered data is quite good. The tool criteria are judged relevant by experts, and the tool performance is adequate: its use should permit the constitution of groups (clustering) of nursing homes homogeneous from the point of view of their nursing care load.

    Validity is a contextual aspect of a scale which may differ across sample populations and study protocols. The objective of our study was to validate the Care-Related Quality of Life Instrument (CarerQol) across two different study design features, sampling framework (general population vs. different care settings) and survey mode (interview vs. written questionnaire). Data were extracted from The Older Persons and Informal Caregivers Minimum DataSet (TOPICS-MDS, www.topics-mds.eu ), a pooled public-access data set with information on >3,000 informal caregivers throughout the Netherlands. Meta-correlations and linear mixed models between the CarerQol's seven dimensions (CarerQol-7D) and caregiver's level of happiness (CarerQol-VAS) and self-rated burden (SRB) were performed. The CarerQol-7D dimensions were correlated to the CarerQol-VAS and SRB in the pooled data set and the subgroups. The strength of correlations between CarerQol-7D dimensions and SRB was weaker among caregivers who were interviewed versus those who completed a written questionnaire. The directionality of associations between the CarerQol-VAS, SRB and the CarerQol-7D dimensions in the multivariate model supported the construct validity of the CarerQol in the pooled population. Significant interaction terms were observed in several dimensions of the CarerQol-7D across sampling frame and survey mode, suggesting meaningful differences in reporting levels. Although good scientific practice emphasises the importance of re-evaluating instrument properties in individual research studies, our findings support the validity and applicability of the CarerQol instrument in a variety of settings. Due to minor differential reporting, pooling CarerQol data collected using mixed administration modes should be interpreted with caution; for TOPICS-MDS, meta-analytic techniques may be warranted.

    Human papillomavirus (HPV) vaccine was approved for girls aged 9-24 years in 2006 to prevent HPV infection and cervical cancer. The Parental Human Papillomavirus Survey (PHPVS) was framed on theoretical constructs of the health belief model (HBM) and developed to survey parents regarding their HPV knowledge, attitudes, and intent to vaccinate. We evaluated the psychometric properties of the PHPVS using classical item analysis and exploratory factor analysis (EFA) among a sample of 200 parents/caregivers. The EFA yielded a 4-factor unidimensional model that explained between 62% and 68% of the total variance depending on the extraction method used. The estimated Cronbach's alpha for the PHPVS was .96. The PHPVS is a reliable measure of HPV knowledge, attitudes, and intent to vaccinate.

    A first order, second class leveling survey in the Mexicali Valley had been just finished in February 2010, for a project carried out by CICESE (Center for Scientific Research and Higher Education of Ensenada), IMTA (Mexican Institute of Water Technology) and CONAGUA (National Water Comission). Immediately after the M=7.2 earthquake the survey was repeated along 240 km of the profiles in the area of the Cerro Prieto pull-apart basin. The leveling started at the LN00 GPS monument in La Puerta. Overall, an uplift of about 30 cm towards the NE, along the 38 km line, in direction SW-NE is observed with larger gradient to the South of the area. Three subsidence bowls differ from this general pattern. One, south from Ejido Saltillo, with the relative subsidence of 19 cm (considering the displacement at LN00 as zero subsidence), probably reflects subsidence of the Saltillo-Guerrero graben; the second, with a subsidence of 23 cm, is situated south from Ejido Nuevo Leon and can be related to the subsidence triggered by the earthquake in the production area of Cerro Prieto IV. For the third one, with relative depth of 36 cm, situated close to Zacamoto, the southeastern limit cannot be determined, so only a comparison with other methods can explain the origin of this anomaly. All the subsidence bowls are associated with liquefaction observed in the area, with more liquefaction observed close to Zacamoto. Since 1996, CICESE has been operating a network of geotechnical instruments (REDECVAM) for continuous recording of deformation related to tectonic (seismic and interseismic) phenomena, as well as anthropogenic deformation caused by the deep fluid extraction at the Cerro Prieto Geothermal Field. The instruments are installed along the faults which limit the Cerro Prieto pull-apart basin at a distance from 8 to 15 km from the epicenter. Coseismic step-like groundwater level changes ranging from 0.4 to 5.0 meters were recorded at 4 wells in the Cerro Prieto Pull apart

    We present a detailed analysis of the spatial distribution of the stellar population and the present-day mass function (PDMF) of the Westerlund 2 (Wd2) region using the data from our high-resolution multiband survey with the Hubble Space Telescope. We used state-of-the-art artificial star tests to determine spatially resolved completeness maps for each of the broadband filters. We reach a level of completeness of 50% down to F555W=24.8 mag (0.7 {M}ȯ ) and F814W=23.3 mag (0.2 {M}ȯ ) in the optical and F125W=20.2 mag and F160W=19.4 mag (both 0.12 {M}ȯ ) in the infrared throughout the field of view. We had previously reported that the core of Wd2 consists of two clumps: namely the main cluster and the northern clump. From the spatial distribution of the completeness-corrected population, we find that their stellar surface densities are 1114 {stars} {{pc}}-2 and 555 {stars} {{pc}}-2, respectively, down to F814W=21.8 mag. We find that the PDMF of Wd2 has a slope of {{Γ }}=-1.46+/- 0.06, which translates to a total stellar cluster mass of (3.6+/- 0.3)\\cdot {10}4 {M}ȯ . The spatial analysis of the PDMF reveals that the cluster population is mass-segregated and most likely primordial. In addition, we report the detection of a stellar population of spatially uniformly distributed low-mass (< 0.15 {M}ȯ ) stars, extending into the gas ridges of the surrounding gas and dust cloud, as well as a confined region of reddened stars, likely caused by a foreground CO cloud. We find hints that a cloud–cloud collision might be the origin of the formation of Wd2.

    Rapid recognition and treatment of myocardial infarction (MI) reduces morbidity and mortality. Although emergency department (ED) nurses are often the first provider to evaluate individuals and are in a prime position to initiate MI guideline recommendations, no valid and reliable instrument was found to quantify their decision-making processes. The purpose of this study was to develop and test the psychometric properties of a new theoretically driven, empirically based instrument for measuring nurses' cardiac triage decisions. Using a descriptive research design, data were collected using a mailed survey. There were 158 ED nurses who completed a mailed questionnaire. Factor analysis revealed three factors (patient presentation, unbiased nurse reasoning process, and nurse action) with good internal consistency (Cronbach's alpha = .903, .809, .718) and sample adequacy (KMO = .758) of the 30-item instrument. The newly developed instrument has the potential to improve patient outcomes surrounding early MI identification and treatment.

    The possibility of prolonging the service life of stomatological instruments by the local hardening of their working parts is discussed. Such hardening should be achieved by using hard and wear-resistant materials. The examples of hardening dental elevators and hard-alloy dental drills are given. New trends in the local hardening of instruments are the treatment of their working parts with laser beams, the application of coating on their surface by the gas-detonation method. The results of research work and trials are presented.

    In this Chapter we review the challenges of, and opportunities for, 3D spectroscopy, and how these have lead to new and different approaches to sampling astronomical information. We describe and categorize existing instruments on 4m and 10m telescopes. Our primary focus is on grating-dispersed spectrographs. We discuss how to optimize dispersive elements, such as VPH gratings, to achieve adequate spectral resolution, high throughput, and efficient data packing to maximize spatial sampling for 3D spectroscopy. We review and compare the various coupling methods that make these spectrographs ``3D,'' including fibers, lenslets, slicers, and filtered multi-slits. We also describe Fabry-Perot and spatial-heterodyne interferometers, pointing out their advantages as field-widened systems relative to conventional, grating-dispersed spectrographs. We explore the parameter space all these instruments sample, highlighting regimes open for exploitation. Present instruments provide a foil for future development. We give an...

    Instrumental reasons play a central role in our practical deliberations because we apply the distinction between reasonable and unreasonable not only to beliefs, but to actions also. The question of what one has an instrumental reason to do is an important substantive question that is relevant to the general theory of practical reasoning and to ethics, too. It will be my object in the present study to show that we have different kinds of instrumental reasons, which depend solely on their logi...

    This paper gives an overview of the CARMENES instrument and of the survey that will be carried out with it during the first years of operation. CARMENES (Calar Alto high-Resolution search for M dwarfs with Exoearths with Near-infrared and optical Echelle Spectrographs) is a next-generation radial-velocity instrument under construction for the 3.5m telescope at the Calar Alto Observatory by a consortium of eleven Spanish and German institutions. The scientific goal of the project is conducting a 600-night exoplanet survey targeting ~ 300 M dwarfs with the completed instrument. The CARMENES instrument consists of two separate echelle spectrographs covering the wavelength range from 0.55 to 1.7 μm at a spectral resolution of R = 82,000, fed by fibers from the Cassegrain focus of the telescope. The spectrographs are housed in vacuum tanks providing the temperature-stabilized environments necessary to enable a 1 m/s radial velocity precision employing a simultaneous calibration with an emission-line lamp or with a Fabry-Perot etalon. For mid-M to late-M spectral types, the wavelength range around 1.0 μm (Y band) is the most important wavelength region for radial velocity work. Therefore, the efficiency of CARMENES has been optimized in this range. The CARMENES instrument consists of two spectrographs, one equipped with a 4k x 4k pixel CCD for the range 0.55 - 1.05 μm, and one with two 2k x 2k pixel HgCdTe detectors for the range from 0.95 - 1.7μm. Each spectrograph will be coupled to the 3.5m telescope with two optical fibers, one for the target, and one for calibration light. The front end contains a dichroic beam splitter and an atmospheric dispersion corrector, to feed the light into the fibers leading to the spectrographs. Guiding is performed with a separate camera; on-axis as well as off-axis guiding modes are implemented. Fibers with octagonal cross-section are employed to ensure good stability of the output in the presence of residual guiding errors. The

    We devised an algorithm for integrating similar clinical research data collection instruments to create a common measurement instrument. We tested this algorithm using questions from several similar surveys. We encountered differing levels of granularity among questions and responses across surveys resulting in either the loss of granularity or data. This algorithm may make survey integration more systematic and efficient.

  14. The U.S. Geological Survey's Earthquake Summary Posters: A GIS-based Education and Communication Product for Presenting Consolidated Post-Earthquake Information

    Science.gov (United States)

    Tarr, A.; Benz, H.; Earle, P.; Wald, D. J.

    2003-12-01

    Earthquake Summary Posters (ESP's), a new product of the U.S. Geological Survey's Earthquake Program, are produced at the National Earthquake Information Center (NEIC) in Golden. The posters consist of rapidly-generated, GIS-based maps made following significant earthquakes worldwide (typically M>7.0, or events of significant media/public interest). ESP's consolidate, in an attractive map format, a large-scale epicentral map, several auxiliary regional overviews (showing tectonic and geographical setting, seismic history, seismic hazard, and earthquake effects), depth sections (as appropriate), a table of regional earthquakes, and a summary of the reional seismic history and tectonics. The immediate availability of the latter text summaries has been facilitated by the availability of Rapid, Accurate Tectonic Summaries (RATS) produced at NEIC and posted on the web following significant events. The rapid production of ESP's has been facilitated by generating, during the past two years, regional templates for tectonic areas around the world by organizing the necessary spatially-referenced data for the map base and the thematic layers that overlay the base. These GIS databases enable scripted Arc Macro Language (AML) production of routine elements of the maps (for example background seismicity, tectonic features, and probabilistic hazard maps). However, other elements of the maps are earthquake-specific and are produced manually to reflect new data, earthquake effects, and special characteristics. By the end of this year, approximately 85% of the Earth's seismic zones will be covered for generating future ESP's. During the past year, 13 posters were completed, comparable to the yearly average expected for significant earthquakes. Each year, all ESPs will be published on a CD in PDF format as an Open-File Report. In addition, each is linked to the special event earthquake pages on the USGS Earthquake Program web site (http://earthquake.usgs.gov). Although three formats

    as a case, this paper examines whether non-economic rationales may trump economic ones in farmer decisions, and, unlike previous research, we quantify how widespread non-economic values are compared to more economic values. Data derive from a survey (1164 responses) of Danish conventional farmers' decision...... to policy instruments; farmers who focus on yield indicate less responsiveness to economic policy instruments. The results imply that it is important to implement a broad array of policy instruments to match different farmer rationales....

    Reducing consumption volumes or introducing climate conscious consumption patterns can be efficient ways to mitigate climate change. Twenty existing policy instruments affecting the greenhouse gas emissions of housing, passenger traffic and food are described in this report of the KUILU-project. The policy instruments and the possibilities to develop effective instrument packages were discussed in two expert workshops, the results of which are presented in annexes of this report. There are already several policy instruments that target on housing and passenger traffic. Their differences in estimated emission reductions are large, which can ease the prioritization and selection of the instruments for further development. So far, only one policy instrument exists that aims to reduce the climate impacts of food choices, namely a Council of State Decision of Principle on Promoting Sustainability in Public Purchasing. However, it includes several measures that can be used to influence private companies and citizens, and thus it opens the field of policy instrument for mitigation of climate impacts of food. According to the expert survey, the most effective policy instrument involved in the analysis was building regulations, and the four most effective instruments after this were the following: gradated procurement tax of cars based on emissions, gradation of car tax, taxation of transport fuels, energy taxes of housing, and the effect of ecodesign directive on appliances. The effectiveness of policy instruments related to food was assessed to be on average level. The five least effective instruments were: EU energy label, voluntary energy experts, the tax of beverage packing, energy certificates, and subsidies for energy efficiency reparation in buildings.

    Full Text Available Background: The aim of the article is to verify the logistics and marketing instruments used in transport enterprises in Lubuskie voivodeship. The article presents the results of surveys of transport companies. Based on these studies in transport enterprises in Lubuskie, the current level of the use of logistics and marketing instruments was determined. Logistics and marketing instruments were separated to study the needs of transport companies in Lubuskie voivodeship. The choice of these instruments gave rise to a study f the possibility of using them in the implementation of business operations. From the findings it can be inferred that they are useful for the voivodeship, and that such a system can be implemented in the whole country. Methods: The study was conducted in the second half of 2014 and 140 transport enterprises in Lubuskie. Based on the research results, classifications of instruments were developed using logistics and marketing division at their levels. Results: On the basis of these findings and observations, the authors have analysed the levels of identification instruments, logistics and marketing. On this basis, it was possible to identify the instruments used by logistics and marketing in these companies. Conclusions: Based on the study of transport companies in Lubuskie voivodeship, a selection of logistics and marketing instruments were identified, along with a classification of the logistics and marketing instruments used. With the implementation of the above steps to classify the usage level of logistics and marketing instruments, the ability to match these levels to data transport companies was established.

    Clinicians continue to be compelled to evaluate the impact of immunosuppressive medication side effects on the quality of life of transplant recipients. We Were asked to develop an instrument to measure side effects in immunosuppressed transplant recipients. To construct an instrument that measures the impact and severity of side effects of immunosuppressive medications used in transplantation and to assess the reliability and validity of the newly developed instrument called the Memphis Survey. The instrument was constructed by a panel of physicians, nurses, and pharmacists with experience in treating transplant recipients. A small group of kidney transplant recipients (n= 13) provided pilot data for refining and testing the instrument. A national sample of kidney, liver, and heart transplant recipients (n = 505) provided data that were used to further develop the instrument. Factor analysis was used to determine the psychological dimensions underlying the instrument and to guide the construction of scales from the survey items. The instrument scales were then computed from the dataset of 505 transplant recipients to quantify the impact of immunosuppressant side effects on the quality of life of transplant recipients. Analyses showed the final instrument scales to be valid and reliable. Exploratory analysis suggests the need for further testing of the instrument to determine gender differences.

  4. Z-Spec: A broadband spectrometer for millimeter-wave astrophysics---Instrument development and results of a molecular line survey of nearby star-forming galaxy NGC 253

    Science.gov (United States)

    Earle, Lieko

    We have built Z-Spec, a broadband spectrometer for millimeter-wave astrophysics. The instrument's instantaneous bandwidth of 185-305 GHz covers the entire 1 millimeter atmospheric transmission window with a moderate resolving power ( R = n/Dn) of 250-350. The spectrometer employs a novel architecture called WaFIRS (Waveguide Far-Infrared Spectrometer) which confines the light propagation for a curved diffraction grating within a parallel-plate waveguide, resulting in a minimum mechanical envelope. An array of 160 silicon- nitride micromesh bolometers is cooled to 60 mK via an adiabatic demagnetization refrigerator (ADR) backed by a closed-cycle 3 He- 4 He sorption pump refrigerator. Z-Spec's compact design serves as a concept demonstration for a future far-infrared spectrometer aboard a cold telescope in space. Routine observations with Z-Spec from the Caltech Submillimeter Observatory on Mauna Kea have been conducted since April 2006, and the instrument currently achieves good sensitivities that are within a factor of two of the photon background limit set by the atmosphere and telescope. Z-Spec's primary science objectives are to determine the redshifts of faint submillimeter galaxies using the 12 CO rotational ladder, and to conduct systematic line surveys of local galaxies. The millimeter waveband hosts low- to mid- J rotational transitions for several molecular species which trace the dense interstellar gas associated with active star formation. Z-Spec's bandwidth offers a unique advantage over the traditional single-dish heterodyne approach: the spectral lines and the corresponding continua are all observed simultaneously, greatly reducing relative uncertainties in flux calibration and line-to-continuum ratios. The starburst galaxy NGC 253 was observed with Z-Spec in November 2006, for a total integration of 3.49 hours over two nights. NGC 253 is one of the brightest neighbors outside the Local Group of galaxies and its compact nuclear region is a site of

    The main goal of the CARMENES instrument is to perform high-accuracy measurements of stellar radial velocities (1m/s) with long-term stability. CARMENES will be installed in 2015 at the 3.5 m telescope in the Calar Alto Observatory (Spain) and it will be equipped with two spectrographs covering from the visible to the near-infrared. It will make use of its near-IR capabilities to observe late-type stars, whose peak of the spectral energy distribution falls in the relevant wavelength interval. The technology needed to develop this instrument represents a challenge at all levels. We present two software packages that play a key role in the control layer for an efficient operation of the instrument: the Instrument Control System (ICS) and the Operational Scheduler. The coordination and management of CARMENES is handled by the ICS, which is responsible for carrying out the operations of the different subsystems providing a tool to operate the instrument in an integrated manner from low to high user interaction level. The ICS interacts with the following subsystems: the near-IR and visible channels, composed by the detectors and exposure meters; the calibration units; the environment sensors; the front-end electronics; the acquisition and guiding module; the interfaces with telescope and dome; and, finally, the software subsystems for operational scheduling of tasks, data processing, and data archiving. We describe the ICS software design, which implements the CARMENES operational design and is planned to be integrated in the instrument by the end of 2014. The CARMENES operational scheduler is the second key element in the control layer described in this contribution. It is the main actor in the translation of the survey strategy into a detailed schedule for the achievement of the optimization goals. The scheduler is based on Artificial Intelligence techniques and computes the survey planning by combining the static constraints that are known a priori (i.e., target

    A desire has recently been increasing that with the rapidly aging society, old people themselves live an independent life without troubles. To realize it, support from the whole society is indispensable. For the reference, the paper made a questionnaire survey on daily life and the needs in use of electricity to the retired and their spouses of the Hokuriku Electric Power Company. The questionnaire was sent to 300 persons with age over 65 living in three Hokuriku prefectures, 74% of which answered. Questions were asked on eight items like physically subjective symptoms, anxieties felt daily, burdens in daily life. Anxieties such as sickness, care and loneliness are taken notice of among old people. In the future, the following are expected: networking with a core formed by people paying visits to the aged, emergency informing system, full-scale introduction of a supporting system with data communication as media, consulting service for the use of electric home appliances, etc. 12 figs.

    In recent years, due to the rapid development of infrastructure and the conduct of the 5. 12 post-disaster reconstruction in China, topographic measurements increased significantly. However, as many of the construction area of the terrain is more complicated, for measurements made new demands, in addition to improving the conventional measurement methods, more efficient e-quipment are also needed to provide technical support. In this paper, taking Xianxugou 1:500 post-earthquake Geological Disaster Engineering Projects in Jiuzhaigou County of Sichuan Province for example, it introduced the principle of super total station in topographic measurement Combined with the construction area, it discussed the implementation methods, notes, measuring result' s repeatability and reproducibility and so on were analyzed. Finally, a method of measuring in complex terrain was taken. Super total station had more advantage than common measurement instruments in complex topographical surveys. This method would have a significant impact on other surveys.%由于很多施工区域的地形较为复杂,对测量工作提出了新的要求,除改进常规测量方法外,同时需要更高效的仪器提供技术保障.本文以震后四川省九寨沟县鲜浒沟地质灾害工程1:500地形测绘项目为例,介绍了超站仪在地形测量中的应用原理,结合施工区,讨论了其实施方法、注意事项、对测量成果的重复性、复现性等问题进行了分析,提出了复杂地形测量的新方法.实践证明,超站仪在复杂地形测量工作中较常规测量仪器有较大的优势.

  10. Comparison of Satellite Surveying to Traditional Surveying Methods for the Resources Industry

    Science.gov (United States)

    Osborne, B. P.; Osborne, V. J.; Kruger, M. L.

    Modern ground-based survey methods involve detailed survey, which provides three-space co-ordinates for surveyed points, to a high level of accuracy. The instruments are operated by surveyors, who process the raw results to create survey location maps for the subject of the survey. Such surveys are conducted for a location or region and referenced to the earth global co- ordinate system with global positioning system (GPS) positioning. Due to this referencing the survey is only as accurate as the GPS reference system. Satellite survey remote sensing utilise satellite imagery which have been processed using commercial geographic information system software. Three-space co-ordinate maps are generated, with an accuracy determined by the datum position accuracy and optical resolution of the satellite platform.This paper presents a case study, which compares topographic surveying undertaken by traditional survey methods with satellite surveying, for the same location. The purpose of this study is to assess the viability of satellite remote sensing for surveying in the resources industry. The case study involves a topographic survey of a dune field for a prospective mining project area in Pakistan. This site has been surveyed using modern surveying techniques and the results are compared to a satellite survey performed on the same area.Analysis of the results from traditional survey and from the satellite survey involved a comparison of the derived spatial co- ordinates from each method. In addition, comparisons have been made of costs and turnaround time for both methods.The results of this application of remote sensing is of particular interest for survey in areas with remote and extreme environments, weather extremes, political unrest, poor travel links, which are commonly associated with mining projects. Such areas frequently suffer language barriers, poor onsite technical support and resources.

    The cores of clusters at 0 $\\lesssim$ z $\\lesssim$ 1 are dominated by quiescent early-type galaxies, whereas the field is dominated by star-forming late-type ones. Galaxy properties, notably the star formation (SF) ability, are altered as they fall into overdense regions. The critical issues to understand this evolution are how the truncation of SF is connected to the morphological transformation and the responsible physical mechanism. The GaLAxy Cluster Evolution Survey (GLACE) is conducting a study on the variation of galaxy properties (SF, AGN, morphology) as a function of environment in a representative sample of clusters. A deep survey of emission line galaxies (ELG) is being performed, mapping a set of optical lines ([OII], [OIII], H$\\beta$ and H$\\alpha$/[NII]) in several clusters at z $\\sim$ 0.40, 0.63 and 0.86. Using the Tunable Filters (TF) of OSIRIS/GTC, GLACE applies the technique of TF tomography: for each line, a set of images at different wavelengths are taken through the TF, to cover a rest fra...

  14. Developments in analytical instrumentation

    Science.gov (United States)

    Petrie, G.

    The situation regarding photogrammetric instrumentation has changed quite dramatically over the last 2 or 3 years with the withdrawal of most analogue stereo-plotting machines from the market place and their replacement by analytically based instrumentation. While there have been few new developments in the field of comparators, there has been an explosive development in the area of small, relatively inexpensive analytical stereo-plotters based on the use of microcomputers. In particular, a number of new instruments have been introduced by manufacturers who mostly have not been associated previously with photogrammetry. Several innovative concepts have been introduced in these small but capable instruments, many of which are aimed at specialised applications, e.g. in close-range photogrammetry (using small-format cameras); for thematic mapping (by organisations engaged in environmental monitoring or resources exploitation); for map revision, etc. Another innovative and possibly significant development has been the production of conversion kits to convert suitable analogue stereo-plotting machines such as the Topocart, PG-2 and B-8 into fully fledged analytical plotters. The larger and more sophisticated analytical stereo-plotters are mostly being produced by the traditional mainstream photogrammetric systems suppliers with several new instruments and developments being introduced at the top end of the market. These include the use of enlarged photo stages to handle images up to 25 × 50 cm format; the complete integration of graphics workstations into the analytical plotter design; the introduction of graphics superimposition and stereo-superimposition; the addition of correlators for the automatic measurement of height, etc. The software associated with this new analytical instrumentation is now undergoing extensive re-development with the need to supply photogrammetric data as input to the more sophisticated G.I.S. systems now being installed by clients, instead

  20. Instrumental variables and Mendelian randomization with invalid instruments

    Science.gov (United States)

    Kang, Hyunseung

    Instrumental variables (IV) methods have been widely used to determine the causal effect of a treatment, exposure, policy, or an intervention on an outcome of interest. The IV method relies on having a valid instrument, a variable that is (A1) associated with the exposure, (A2) has no direct effect on the outcome, and (A3) is unrelated to the unmeasured confounders associated with the exposure and the outcome. However, in practice, finding a valid instrument, especially those that satisfy (A2) and (A3), can be challenging. For example, in Mendelian randomization studies where genetic markers are used as instruments, complete knowledge about instruments' validity is equivalent to complete knowledge about the involved genes' functions. The dissertation explores the theory, methods, and application of IV methods when invalid instruments are present. First, when we have multiple candidate instruments, we establish a theoretical bound whereby causal effects are only identified as long as less than 50% of instruments are invalid, without knowing which of the instruments are invalid. We also propose a fast penalized method, called sisVIVE, to estimate the causal effect. We find that sisVIVE outperforms traditional IV methods when invalid instruments are present both in simulation studies as well as in real data analysis. Second, we propose a robust confidence interval under the multiple invalid IV setting. This work is an extension of our work on sisVIVE. However, unlike sisVIVE which is robust to violations of (A2) and (A3), our confidence interval procedure provides honest coverage even if all three assumptions, (A1)-(A3), are violated. Third, we study the single IV setting where the one IV we have may actually be invalid. We propose a nonparametric IV estimation method based on full matching, a technique popular in causal inference for observational data, that leverages observed covariates to make the instrument more valid. We propose an estimator along with

    Surveys with questionnaires play a vital role in decision and policy making in society. Within medicine, including otolaryngology, surveys with questionnaires may be the only method for gathering data on rare or unusual events. In addition, questionnaires can be developed and validated to be used as outcome measures in clinical trials and other clinical research architecture. Consequently, it is fundamentally important that such tools be properly developed and validated. Just asking questions that have not gone through rigorous design and development may be misleading and unfair at best; at worst, they can result in under- or overtreatment and unnecessary expense. Furthermore, it is important that consumers of the data produced by these instruments understand the principles of questionnaire design to interpret results in an optimal and meaningful way. This article presents a practical guide for understanding the methodologies of survey and questionnaire design, including the concepts of validity and reliability, how surveys are administered and implemented, and, finally, biases and pitfalls of surveys.

    The objective of this study was to develop a valid and reliable instrument to measure the job satisfaction of physicians practicing emergency medicine. A prospective survey involving four separate stages (an item evaluation and reduction stage, a factor analysis stage, a construct validity stage, and a reliability stage) was distributed in Canada to full-time emergency physicians. Three separate survey instruments were administered (an initial draft instrument with 228 items, a pilot instrument with 142 items, and the final instrument with 79 items). Construct validity of the final instrument was tested by evaluating the correlation between physician scores on the instrument, and scores on two instruments measuring the same construct, and three measuring different but related constructs. A draft instrument with 228 items and six hypothetical domains was tested on 61 physicians. Evaluation for frequency endorsement, redundancy, and homogeneity reduced the item pool to 157. The remaining 157 items were used as a pilot instrument and tested on 223 physicians. Factor analysis eliminated 66 items from the pilot instrument, creating a final instrument with 79 items, 11 factors, and six domains. Cronbach's coefficient alpha for the final instrument domains is 0.81, and all domain-total correlations are greater than 0.4. All correlations between the final instrument and the construct validity instruments were statistically significant (P job satisfaction, which is both internally consistent and stable.

  4. IRIS Controlled Source Seismic Experiments: Continental Structure, Instrumentation, and Education

    2004-12-01

    The controlled-source seismology program of IRIS/PASSCAL has made major contributions to the study of continental structure and evolution. It has also undergone major developments in seismic instrumentation. The first PASSCAL experiments (1984/85) targeted the Basin and Range Province and the Ouachita orogenic belt. The Basin and Range study provided remarkably clear images of this thin, highly-extended crust, while the Ouachita experiment tested competing hypotheses for the deep structure of this Paleozoic orogen. However, both of these projects were limited by a lack of seismic instruments. The situation improved in the late 1980's with the benefit of a mixed array of 600 seismic recorders from the USGS, Stanford, and the Geological Survey of Canada. The resolution achieved with these instruments was revolutionary. Results include the imaging of such remarkable features as crustal-scale duplexes in the Brooks Range compressional orogen of northern Alaska, and of crustal "core complexes" in the extended crust of southwest Arizona. The 3-channel PASSCAL Jr. instrument was developed, leading to experiments in which ˜1000 instruments were deployed, including three-component recording. This complex mix of instruments served the community well for several years, but required large, complex instrument centers and lots of technical support. With input from PASSCAL and the international community, a newly designed, compact instrument (the Texan) was finalized in the spring of 1998, and the first 200 instruments was delivered to the Univ. of Texas-El Paso in late 1998. The present instrument pool of Texans exceeds 1,400 and these have been used on such projects as the high-resolution imaging of the Los Angeles and San Fernando basins (LARSE I and II experiments), where active thrust faults have been imaged. Controlled-source seismic experiments are now very numerous. During calendar year 2004 alone, portable Texan instruments have traveled from Venezuela to Denmark

  5. Measurement equivalence in mixed mode surveys

    2015-02-01

    Full Text Available Surveys increasingly use mixed mode data collection (e.g., combining face-to-face and web because this controls costs and helps to maintain good response rates. However, a combination of different survey modes in one study, be it cross-sectional or longitudinal, can lead to different kinds of measurement errors. For example, respondents in a face-to-face survey or a web survey may interpret the same question differently, and might give a different answer, just because of the way the question is presented. This effect of survey mode on the question-answer process is called measurement mode effect. This study develops methodological and statistical tools to identify the existence and size of mode effects in a mixed mode survey. In addition, it assesses the size and importance of mode effects in measurement instruments using a specific mixed mode panel survey (Netherlands Kinship Panel Study. Most measurement instruments in the NKPS are multi-item scales, therefore confirmatory factor analysis (CFA will be used as the main analysis tool, using propensity score methods to correct for selection effects.The results show that the NKPS scales by and large have measurement equivalence, but in most cases only partial measurement equivalence. Controlling for respondent differences on demographic variables, and on scale scores from the previous uni-mode measurement occasion, tends to improve measurement equivalence, but not for all scales. The discussion ends with a review of the implications of our results for analyses employing these scales.

    The Palos Verdes Fault (PVF) is one of few active faults in Southern California that crosses the shoreline and can be studied using both terrestrial and subaqueous methodologies. To characterize the near-seafloor fault morphology, tectonic influences on continental slope sedimentary processes and late Pleistocene to present slip rate, a grid of high-resolution multibeam bathymetric data, and chirp subbottom profiles were acquired with an autonomous underwater vehicle (AUV) along the main trace of PVF in water depths between 250 and 600 m. Radiocarbon dates were obtained from vibracores collected using a remotely operated vehicle (ROV) and ship-based gravity cores. The PVF is expressed as a well-defined seafloor lineation marked by subtle along-strike bends. Right-stepping transtensional bends exert first-order control on sediment flow dynamics and the spatial distribution of Holocene depocenters; deformed strata within a small pull-apart basin record punctuated growth faulting associated with at least three Holocene surface ruptures. An upper (shallower) landslide scarp, a buried sedimentary mound, and a deeper scarp have been right-laterally offset across the PVF by 55 ± 5, 52 ± 4 , and 39 ± 8 m, respectively. The ages of the upper scarp and buried mound are approximately 31 ka; the age of the deeper scarp is bracketed to 17–24 ka. These three piercing points bracket the late Pleistocene to present slip rate to 1.3–2.8 mm/yr and provide a best estimate of 1.6–1.9 mm/yr. The deformation observed along the PVF is characteristic of strike-slip faulting and accounts for 20–30% of the total right-lateral slip budget accommodated offshore Southern California.

    In this study, an investigation of 231 articles of the oral communication sections presented at the National Symposium on Physics Teaching (NSPT) was conducted, trying to identify those related to Information and Communication Technology (ICT), its form of organization, the involved thematic areas and the degree of teaching, allowing to compare the different perspectives and trends in this field. The conducted state of the art-study had a bibliographical character and qualitative contours involving content analysis. It was realized that the thematic area "Information technology, technology diffusion and Physics teaching", where most of the research related to ICT is concentrated, represent 11.7% of the total number of papers at the XIX NSPT, confirming a trend of research in this area. It was found, among other things, the predominance of studies where learning objects are used in Physics Education, especially in High School and University Education; the use of ICT in multidisciplinary work and that some features need to be further explored, such as thermodynamics. It was also noted an expressive amount of studies involving the use of ICT in teacher training proposals, which can contribute to the enlargement of the methodological options of teachers and meet their training needs.

    There is evidence suggesting that the nutritional content of recipes promoted by celebrity chefs or television cooking programmes contradict healthy eating guidelines. This study aims to investigate people's attitudes and beliefs about popular television cooking programmes and celebrity chefs. Males and females who watch television cooking programmes were recruited to participate in a self-administered online questionnaire (22-items) which included multiple-choice and rank order questions. A total of n = 207 participants undertook the questionnaire with fully completed questionnaires available for n = 150 participants (Males, n = 22; Females, n = 128; aged 38.4 ± 14 years). The majority of respondents watch ≤30 minutes of television cooking programming per day (total responses, n = 153/207; 74%) with almost three-quarters (total responses, n = 130/175; 74%) having attempted a recipe. New cooking ideas (total responses, n = 81/175; 46%) and entertainment (total responses, n = 64/175; 36.5%) were the two main reasons participants gave for watching these programmes. Significantly more respondents believed recipes use excessive amounts of unhealthy fat, sugar or salt (unhealthy: 24%; healthy: 7%; P people watch these programmes. However results generated from the present study are descriptive and subjective and further investigation into the impact of television cooking programmes and celebrity chefs on behavioural change requires attention. Further investigation including a systematic investigation into the dietary quality of recipes promoted by celebrity chefs against national healthy eating benchmarks is also warranted.

    Christian, David E. (Danbury, CT)

    1990-07-24

    The present invention relates to a musical instrument amplifier which is particularly useful for electric guitars. The amplifier has a rigid body for housing both the electronic system for amplifying and processing signals from the guitar and the system's power supply. An input plug connected to and projecting from the body is electrically coupled to the signal amplifying and processing system. When the plug is inserted into an output jack for an electric guitar, the body is rigidly carried by the guitar, and the guitar is operatively connected to the electrical amplifying and signal processing system without use of a loose interconnection cable. The amplifier is provided with an output jack, into which headphones are plugged to receive amplified signals from the guitar. By eliminating the conventional interconnection cable, the amplifier of the present invention can be used by musicians with increased flexibility and greater freedom of movement.

    Simulation of systems at an architectural level can offer an effective way to study critical design choices if (1) the performance of the simulator is adequate to examine designs executing significant code bodies, not just toy problems or small application fragements, (2) the details of the simulation include the critical details of the design, (3) the view of the design presented by the simulator instrumentation leads to useful insights on the problems with the design, and (4) there is enough flexibility in the simulation system so that the asking of unplanned questions is not suppressed by the weight of the mechanics involved in making changes either in the design or its measurement. A simulation system with these goals is described together with the approach to its implementation. Its application to the study of a particular class of multiprocessor hardware system architectures is illustrated.

    The Dark Energy Spectroscopic Instrument (DESI) is a Stage IV ground-based dark energy experiment that will study baryon acoustic oscillations (BAO) and the growth of structure through redshift-space distortions with a wide-area galaxy and quasar spectroscopic redshift survey. The DESI instrument consists of a new wide-field (3.2 deg. linear field of view) corrector plus a multi-object spectrometer with up to 5000 robotically positioned optical fibers and will be installed at prime focus on the Mayall 4m telescope at Kitt Peak, Arizona. The fibers feed 10 three-arm spectrographs producing spectra that cover a wavelength range from 360-980 nm and have resolution of 2000-5500 depending on the wavelength. The DESI instrument is designed for a 14,000 sq. deg. multi-year survey of targets that trace the evolution of dark energy out to redshift 3.5 using the redshifts of luminous red galaxies (LRGs), emission line galaxies (ELGs) and quasars. DESI is the successor to the successful Stage-III BOSS spectroscopic redshift survey and complements imaging surveys such as the Stage-III Dark Energy Survey (DES, currently operating) and the Stage-IV Large Synoptic Survey Telescope (LSST, planned start early in the next decade).

    The Visible Integral-Field Replicable Unit Spectrograph (VIRUS) instrument will be installed at the Hobby-Eberly Telescope† in the near future. The instrument will be housed in two enclosures that are mounted adjacent to the telescope, via the VIRUS Support Structure (VSS). We have designed the enclosures to support and protect the instrument, to enable servicing of the instrument, and to cool the instrument appropriately while not adversely affecting the dome environment. The system uses simple HVAC air handling techniques in conjunction with thermoelectric and standard glycol heat exchangers to provide efficient heat removal. The enclosures also provide power and data transfer to and from each VIRUS unit, liquid nitrogen cooling to the detectors, and environmental monitoring of the instrument and dome environments. In this paper, we describe the design and fabrication of the VIRUS enclosures and their subsystems.

  17. RHEED streaks and instrument response

    Energy Technology Data Exchange (ETDEWEB)

    Van Hove, J.M.; Pukite, P.; Cohen, P.I.; Lent, C.S.

    1983-04-01

    Reflection high-energy electron diffraction (RHEED) is so sensitive to surface morphology that it is difficult to separate the roles of instrument response and surface imperfection in the diffraction. To address this difficulty we have used MBE grown GaAs(001) as a test surface to study the angular dimensions of the diffracted beams. This is important if RHEED is to be useful as a quantitive probe of surface structure for in situ studies of crystal growth. The limitations placed by instrumental uncertainties on the maximum resolvable distance are estimated. Measurements of the angular length of the RHEED steaks versus angle of incidence are presented which show the changes expected from a combination of a uniformly broadened reciprocal lattice rod and an instrument limit due to angular uncertainties. Resolvable distances are obtained with RHEED that are much larger than those typically obtained with low-energy electron diffraction.

    It is pointed out that no instrument is sensitive to only one oceanographic variable; rather, each responds to a combination of atmospheric and oceanic phenomena. This complicates data interpretation and usually requires that a number of observations, each sensitive to somewhat different phenomena, be combined to provide unambiguous information. The distinction between active and passive instruments is described. A block diagram illustrating the steps necessary to convert data from satellite instruments into oceanographic information is included, as is a diagram illustrating the operation of a radio-frequency radiometer. Attention is also given to the satellites that carry the various oceanographic instruments.

    Lauritzen, T.; Sah, R.C.

    1979-03-01

    A Laser Surveying System has been developed to survey the beam elements of the PEP storage ring. This system provides automatic data acquisition and analysis in order to increase survey speed and to minimize operator error. Two special instruments, the Automatic Readout Micrometer and the Small Automatic Micrometer, have been built for measuring the locations of fiducial points on beam elements with respect to the light beam from a laser. These instruments automatically encode offset distances and read them into the memory of an on-line computer. Distances along the beam line are automatically encoded with a third instrument, the Automatic Readout Tape Unit. When measurements of several beam elements have been taken, the on-line computer analyzes the measured data, compared them with desired parameters, and calculates the required adjustments to beam element support stands.

  4. Present time

    2014-01-01

    The idea of a moving present or `now' seems to form part of our most basic beliefs about reality. Such a present, however, is not reflected in any of our theories of the physical world. I show in this article that presentism, the doctrine that only what is present exists, is in conflict with modern relativistic cosmology and recent advances in neurosciences. I argue for a tenseless view of time, where what we call `the present' is just an emergent secondary quality arising from the interaction of perceiving self-conscious individuals with their environment. I maintain that there is no flow of time, but just an ordered system of events.

    2016-01-01

    We present a statistical survey of the latitudinal structure of the fast magnetosonic wave mode detected by the Van Allen Probes spanning the time interval of 21 September 2012 to 1 August 2014. We show that statistically, the latitudinal occurrence of the wave frequency (f) normalized by the local proton cyclotron frequency (f(sub cP)) has a distinct funnel-shaped appearance in latitude about the magnetic equator similar to that found in case studies. By comparing the observed E/B ratios with the model E/B ratio, using the observed plasma density and background magnetic field magnitude as input to the model E/B ratio, we show that this mode is consistent with the extra-ordinary (whistler) mode at wave normal angles (theta(sub k)) near 90 deg. Performing polarization analysis on synthetic waveforms composed from a superposition of extra-ordinary mode plane waves with theta(sub k) randomly chosen between 87 and 90 deg, we show that the uncertainty in the derived wave normal is substantially broadened, with a tail extending down to theta(sub k) of 60 deg, suggesting that another approach is necessary to estimate the true distribution of theta(sub k). We find that the histograms of the synthetically derived ellipticities and theta(sub k) are consistent with the observations of ellipticities and theta(sub k) derived using polarization analysis.We make estimates of the median equatorial theta(sub k) by comparing observed and model ray tracing frequency-dependent probability occurrence with latitude and give preliminary frequency dependent estimates of the equatorial theta(sub k) distribution around noon and 4 R(sub E), with the median of approximately 4 to 7 deg from 90 deg at f/f(sub cP) = 2 and dropping to approximately 0.5 deg from 90 deg at f/f(sub cP) = 30. The occurrence of waves in this mode peaks around noon near the equator at all radial distances, and we find that the overall intensity of these waves increases with AE*, similar to findings of other studies.

Policy instruments here refers to laws, directives, taxes/fees, national/local goals and other regulating measures that the society introduce to steer the development of the waste management system. This work can thus be used as a dictionary or a guideline for these measures. The investigation has two goals: 1. To give representatives of the Swedish waste management system a summary of important policy instruments for the future development of the waste management system. 2. To give Waste Refinery a summary of these policy instruments that can be used for the discussions of how the research within the centre should develop during stage 2. A large number of policy instruments have been found during the study. These instruments have been, most likely will become, or may become important for the development of the waste management system. Most of them are described in this report. The selection made is presented in Table 1. Focus for the selection has been policy instruments that are important for the research activities within Waste Refinery, meaning policy instruments that direct or indirect can change the use of thermal and/or biological treatment as well as techniques and methods supporting these treatment methods.

    1997-06-01

    Although speech and vocal music are consistently shown to impair serial recall for visually presented items, instrumental music does not always produce a significant disruption. This study investigated the features of instrumental music that would modulate the disruption in serial recall. 24 students were presented sequences of nine digits and required to recall the digits in order of presentation. Instrumental music as played either forward or backward during the task. Forward music caused significantly more disruption than did silence, whereas the reversed music did not. Some higher-order factor may be at work in the effect of background music on serial recall.

    Lucey, Paul G.

    1993-01-01

    The recent successes of the Galileo solid-state imaging (SSI) experiment at the Moon and Gaspra show the utility of multispectral imaging of planetary objects. 'Clementine' is the planetary community's 'code name' for the SDIO (Space Defense Initiative Organization), mission to the Moon and the asteroid Geographos. This mission is designed as a long term stressing test on sensors and space systems developed for SDIO. In the course of this test Clementine will obtain science data using a varied and powerful array of remote sensing instruments which were developed by or for Lawrence Livermore National Laboratory in Livermore, California. Clementine carries five cameras, one for navigation and four for science experiments. In addition, a laser ranger is included which will serve as a laser altimeter. The Clementine cameras cover a wider range of spatial resolutions and wavelength range than did Galileo and are almost ideally suited to mapping of mafic rock types as are present on the Moon and expected at Geographos. Calibration of the cameras will occur at the sensor calibration laboratory at LLNL. In flight calibrations, using standard stars and other standards should improve the stated accuracies. Signal-to-noise ratios (SNRs) include the following noise sources: shot noise, calibration error, digitization noise, readout noise, and frame transfer noise (where applicable). The achieved SNRs are a balance between detector saturation and acceptable image smear. The 'worst' case uses the longest possible integration times.

    1992-09-01

    Developments in mass spectrometry instrumentation over the past three years are reviewed. The subject is characterized by an enormous diversity of designs, a high degree of competition between different laboratories working with either different or similar techniques and by extremely rapid progress in improving analytical performance. Instruments can be grouped into genealogical charts based on their physical and conceptual interrelationships. This is illustrated using mass analyzers of different types. The time course of development of particular instrumental concepts is illustrated in terms of the s-curves typical of cell growth. Examples are given of instruments which are at the exponential, linear and mature growth stages. The prime examples used are respectively: (i) hybrid instruments designed to study reactive collisions of ions with surfaces: (ii) the Paul ion trap; and (iii) the triple quadrupole mass spectrometer. In the area of ion/surface collisions, reactive collisions such as hydrogen radical abstraction from the surface by the impinging ion are studied. They are shown to depend upon the chemical nature of the surface through the use of experiments which utilize self-assembled monolayers as surfaces. The internal energy deposited during surface-induced dissociation upon collision with different surfaces in a BEEQ instrument is also discussed. Attention is also given to a second area of emerging instrumentation, namely technology which allows mass spectrometers to be used for on-line monitoring of fluid streams. A summary of recent improvements in the performance of the rapidly developing quadrupole ion trap instrument illustrates this stage of instrument development. Improvements in resolution and mass range and their application to the characterization of biomolecules are described. The interaction of theory with experiment is illustrated through the role of simulations of ion motion in the ion trap. It is emphasized that mature instruments play a

Consequently, a standardized and meticulous care is essential; they should go through the decontamination, cleaning and sterilization process. These instruments are designed in order to provide surgeons with tools that help them to perform a basic surgical procedure; there are multiple variations and the design depends on their function. This paper aims at showing all surgical instruments that can be used in an operating room during surgery and are not generally included in the medical literature.

  6. TESTING DIFFERENT SURVEY TECHNIQUES TO MODEL ARCHITECTONIC NARROW SPACES

    Directory of Open Access Journals (Sweden)

    A. Mandelli

    2017-08-01

    Full Text Available In the architectural survey field, there has been the spread of a vast number of automated techniques. However, it is important to underline the gap that exists between the technical specification sheet of a particular instrument and its usability, accuracy and level of automation reachable in real cases scenario, especially speaking about Cultural Heritage (CH field. In fact, even if the technical specifications (range, accuracy and field of view are known for each instrument, their functioning and features are influenced by the environment, shape and materials of the object. The results depend more on how techniques are employed than the nominal specifications of the instruments. The aim of this article is to evaluate the real usability, for the 1:50 architectonic restitution scale, of common and not so common survey techniques applied to the complex scenario of dark, intricate and narrow spaces such as service areas, corridors and stairs of Milan’s cathedral indoors. Tests have shown that the quality of the results is strongly affected by side-issues like the impossibility of following the theoretical ideal methodology when survey such spaces. The tested instruments are: the laser scanner Leica C10, the GeoSLAM ZEB1, the DOT DPI 8 and two photogrammetric setups, a full frame camera with a fisheye lens and the NCTech iSTAR, a panoramic camera. Each instrument presents advantages and limits concerning both the sensors themselves and the acquisition phase.

    In the architectural survey field, there has been the spread of a vast number of automated techniques. However, it is important to underline the gap that exists between the technical specification sheet of a particular instrument and its usability, accuracy and level of automation reachable in real cases scenario, especially speaking about Cultural Heritage (CH) field. In fact, even if the technical specifications (range, accuracy and field of view) are known for each instrument, their functioning and features are influenced by the environment, shape and materials of the object. The results depend more on how techniques are employed than the nominal specifications of the instruments. The aim of this article is to evaluate the real usability, for the 1:50 architectonic restitution scale, of common and not so common survey techniques applied to the complex scenario of dark, intricate and narrow spaces such as service areas, corridors and stairs of Milan's cathedral indoors.

    Shoulder instability is a relatively common condition occurring in 2% of the population. PROMIS (Patient-Reported Outcome Measurement Information System) was developed by the National Institutes of Health in an effort to advance patient-reported outcome (PRO) instruments by developing question banks for major health domains. To compare PROMIS instruments to current PRO instruments in patients who would be undergoing operative intervention for recurrent shoulder instability. Cohort study (diagnosis); Level of evidence, 2. A total of 74 patients with a primary diagnosis of shoulder instability who would be undergoing surgery were asked to fill out the American Shoulder and Elbow Surgeons shoulder assessment form (ASES), Marx shoulder activity scale (Marx), Short Form-36 Health Survey Physical Function subscale (SF-36 PF), Western Ontario Shoulder Instability Index (WOSI), PROMIS physical function computer adaptive test (PF CAT), and PROMIS upper extremity item bank (UE). Correlation between PRO instruments was defined as excellent (>0.7), excellent-good (0.61-0.7), good (0.4-0.6), and poor (0.2-0.3). Utilization of the PROMIS UE demonstrated excellent correlation with the SF-36 PF ( r = 0.78, P ceiling effects were present in 28.6% of patients aged 18 to 21 years. Patients, on average, answered 4.6 ± 1.8 questions utilizing the PROMIS PF CAT. The PROMIS UE and PROMIS PF CAT demonstrated good to excellent correlation with common shoulder and upper extremity PRO instruments as well as the SF-36 PF in patients with shoulder instability. In patients aged ≤21 years, there were significant ceiling effects utilizing the PROMIS UE. While the PROMIS PF CAT appears appropriate for use in adults of any age, our findings demonstrate that the PROMIS UE has significant ceiling effects in patients with shoulder instability who are ≤21 years old, and we do not recommend use of the PROMIS UE in this population.

    A robust identification of the instrument currently used by the surgeon is crucial for the automatic modeling and analysis of surgical procedures. Various approaches for intra-operative surgical instrument identification have been presented, mostly based on radio-frequency identification (RFID) or endoscopic video analysis. A novel approach is to identify the instruments on the instrument table of the scrub nurse with a combination of video and weight information. In a previous article, we successfully followed this approach and applied it to multiple instances of an ear, nose and throat (ENT) procedure and the surgical tray used therein. In this article, we present a metric for the suitability of the instruments of a surgical tray for identification by video and weight analysis and apply it to twelve trays of four different surgical domains (abdominal surgery, neurosurgery, orthopedics and urology). The used trays were digitized at the central sterile services department of the hospital. The results illustrate that surgical trays differ in their suitability for the approach. In general, additional weight information can significantly contribute to the successful identification of surgical instruments. Additionally, for ten different surgical instruments, ten exemplars of each instrument were tested for their weight differences. The samples indicate high weight variability in instruments with identical brand and model number. The results present a new metric for approaches aiming towards intra-operative surgical instrument detection and imply consequences for algorithms exploiting video and weight information for identification purposes.

    Full Text Available During his time as a state senator in Illinois, Barack Obama voted “Present” 129 times, a deliberate act of nonvoting that subsequently became an important campaign issue during the 2008 presidential elections. In this article, I examine the use of Present votes in the Illinois state senate. I find evidence that Present votes can largely be characterized as protest votes used as a legislative tool by the minority party. Incorporating information from Present votes into a Bayesian polytomous item-response model, I find that this information increases the efficiency of ideal point estimates by approximately 35%. There is little evidence of significant moderation by Obama when Present votes are accounted for, though my results suggest that Obama’s voting record may have moderated significantly before his subsequent election to the U.S. Senate. My results also suggest that because legislative nonvoting may occur for a variety of reasons, naive inclusion of nonvoting behavior into vote choice models may lead to biased results.

    The Tevatron in Collider Run II (2001-present) is operating with six times more bunches, many times higher beam intensities and luminosities than in Run I (1992-1995). Beam diagnostics were crucial for the machine start-up and the never-ending luminosity upgrade campaign. We present the overall picture of the Tevatron diagnostics development for Run II, outline machine needs for new instrumentation, present several notable examples that led to Tevatron performance improvements, and discuss the lessons for the next big machines--LHC and ILC.

    Few case-finding instruments are available to community healthcare professionals. This review aims to identify short, valid instruments that detect older community-dwellers risk of four adverse outcomes: hospitalisation, functional-decline, institutionalisation and death. Data sources included PubMed and the Cochrane library. Data on outcome measures, patient and instrument characteristics, and trial quality (using the Quality In Prognosis Studies [QUIPS] tool), were double-extracted for derivation-validation studies in community-dwelling older adults (>50 years). Forty-six publications, representing 23 unique instruments, were included. Only five were externally validated. Mean patient age range was 64.2-84.6 years. Most instruments n=18, (78%) were derived in North America from secondary analysis of survey data. The majority n=12, (52%), measured more than one outcome with hospitalisation and the Probability of Repeated Admission score the most studied outcome and instrument respectively. All instruments incorporated multiple predictors. Activities of daily living n=16, (70%), was included most often. Accuracy varied according to instruments and outcomes; area under the curve of 0.60-0.73 for hospitalisation, 0.63-0.78 for functional decline, 0.70-0.74 for institutionalisation and 0.56-0.82 for death. The QUIPS tool showed that 5\\/23 instruments had low potential for bias across all domains. This review highlights the present need to develop short, reliable, valid instruments to case-find older adults at risk in the community.

    Since 2004 NASA has surveyed users of its Earth Observing System Data and Information System (EOSDIS) to determine user satisfaction with its services. The surveys have been conducted by CFI Group under contract with the Federal Consulting Group, Executive Agent in government for the American Customer Satisfaction Index (ACSI). The purpose of these annual surveys is to help EOSDIS and the data centers assess current status and improve future services. The survey questions include demographic and experiential questions in addition to the ACSI and EOSDIS specific rating questions. In addition to customer satisfaction, analysis of each year's results has provided insight into the survey process. Although specific questions have been added, modified, or deleted to reflect changes to the EOSDIS system and processes, the model rating questions have remained the same to ensure consistency for evaluating cross year trends. Working with the CFI Group, we have refined the invitation and questions to increase clarity and address the different ways diverse groups of users access services at EOSDIS data centers. We present challenges in preparing a single set of questions that go to users with backgrounds in many Earth science disciplines. These users may have contacted any of the 12 EOSDIS data centers for information or may have accessed data or data products from many kinds of aircraft and satellite instruments. We discuss lessons learned in preparing the invitation and survey questions and the steps taken to make the survey easier to complete and to encourage increased participation.

    2010-01-01

    We describe telescopes and instruments that were developed and used for astronomical research in the ultraviolet (UV) and extreme ultraviolet (EUV) regions of the electromagnetic spectrum. The wavelength ranges covered by these bands are not uniquely defined. We use the following convention here: The EUV and UV span the regions ~100-912 and 912-3000 Angstroem respectively. The limitation between both ranges is a natural choice, because the hydrogen Lyman absorption edge is located at 912 Angstroem. At smaller wavelengths, astronomical sources are strongly absorbed by the interstellar medium. It also marks a technical limit, because telescopes and instruments are of different design. In the EUV range, the technology is strongly related to that utilized in X-ray astronomy, while in the UV range the instruments in many cases have their roots in optical astronomy. We will, therefore, describe the UV and EUV instruments in appropriate conciseness and refer to the respective chapters of this volume for more technic...

    Signal processing techniques in acoustics address many concerns. Included are such things as wave propagation variables, amplitude considerations, spectral content, wavelength, and phase. Phase is primarily of concern when waves interact with each other, as well as with a medium, and the imposition of boundary conditions leads to normal mode vibrations. Such conditions are prevalent in all musical instruments, and thus relevant signal processing techniques are essential to both understanding and modeling the structure of musical instruments and the sound radiated.

    Although urinary incontinence is common in children, no validated pediatric instruments exist for measuring urinary incontinence symptoms and bother. We developed and validated a patient reported pediatric survey for urinary incontinence measurement. The Incontinence Symptom Index-Pediatric is an 11-item instrument comprising 2 domains, that is 1) impairment and 2) symptom severity, including subdomains for stress urinary incontinence, urge urinary incontinence, insensate urinary incontinence, nocturnal urinary incontinence and pad use. The survey was self-administered twice, 2 weeks apart, to boys and girls ages 11 to 17 years. Children completed the survey independently. Cases consisted of patients presenting to pediatric urology clinic with the chief complaint of urinary incontinence. Controls consisted of healthy children presenting for evaluation up at a general pediatric practice. Formal validation analysis was performed. A total of 19 subjects per arm completed at least 1 survey. Internal consistency was good with a Cronbach's alpha of 0.84 for the complete instrument. Item-scale correlations were greater than 0.60 for all except 1 item. Test-retest reliability was also good (r = 0.97, p <0.0001). Discriminative validity was good with a total severity scale score of 9.3 in wet children and 0.7 in controls (p <0.0001). Impairment scale scores differed by 2.2 points (p <0.0001). Mean scores differed significantly between subscales for all domains except pad use. The most dramatic difference was in the urge urinary incontinence domain, which differed by a mean of 3.6 points (p = 0.0002). This pilot study provides initial validation of a survey instrument for urinary incontinence in children and adolescents. This instrument can be used in children ages 11 to 17 years to objectively and reproducibly measure patient reported urinary incontinence.

    In this paper we present the development and validation of a Mathematics Teaching Pedagogical and Discourse Beliefs Instrument (MTPDBI), a 20 item partial-credit survey designed and analyzed using Rasch measurement theory. Items on the MTPDBI address beliefs about the nature of mathematics, teaching and learning mathematics, and classroom discourse practices. A Rasch partial credit model (Masters, 1982) was estimated from the pilot study data. Results show that item separation reliability is .96 and person separation reliability is .71. Other analyses indicate the instrument is a viable measure of secondary teachers' beliefs about reform-oriented mathematics teaching and learning. This instrument is proposed as a useful measure of teacher beliefs for those working with pre-service and in-service teacher development.

    The oral language development depends on the effective development of the hearing system. In cases of children presenting with hearing loss, a cochlear implant is an electronic device indicated to (re)habilitate the hearing function. Thus, it is of paramount importance to assess and follow the oral language development of children fitted with a cochlear implant (CI) to measure the effectiveness of the electronic device and support the therapeutic planning of these children. Questions are currently being raised about the instruments to assess the oral language of children using a CI, and, seeking the answers, this systematic review aimed at surveying these instruments. Searches were performed in three different databases utilizing six different descriptors to select articles published from 2004 to 2009 that performed an oral language assessment of children with a CI. Initially, 373 articles were found, and, after the application of inclusion criteria, 47 articles were analyzed, resulting in a survey of 74 instruments for oral language assessment, including tests, questionnaires and inventories. In analyzing the articles, it was realized that the studies included in this systematic review presented varied methodologies and low levels of evidence, with a greater concentration of instruments assessing receptive and expressive language, emphasizing the survey of the child's vocabulary and questionnaires. Thus, it can be verified that other linguistic skills, such as morphosyntactic, semantic, and narrative-pragmatic ones that are important in structuring speech and language for the effectiveness of the child's speech, are not being focused on. Just one of the instruments cited, a questionnaire, was specific for the oral language assessment of children with cochlear implants.

  10. Increased Science Instrumentation Funding Strengthens Mars Program

    2012-01-01

    As the strategic knowledge gaps mature for the exploration of Mars, Mars sample return (MSR), and Phobos/Deimos missions, one approach that becomes more probable involves smaller science instrumentation and integrated science suites. Recent technological advances provide the foundation for a significant evolution of instrumentation; however, the funding support is currently too small to fully utilize these advances. We propose that an increase in funding for instrumentation development occur in the near-term so that these foundational technologies can be applied. These instruments would directly address the significant knowledge gaps for humans to Mars orbit, humans to the Martian surface, and humans to Phobos/ Deimos. They would also address the topics covered by the Decadal Survey and the Mars scientific goals, objectives, investigations and priorities as stated by the MEPAG. We argue that an increase of science instrumentation funding would be of great benefit to the Mars program as well as the potential for human exploration of the Mars system. If the total non-Earth-related planetary science instrumentation budget were increased 100% it would not add an appreciable amount to the overall NASA budget and would provide the real potential for future breakthroughs. If such an approach were implemented in the near-term, NASA would benefit greatly in terms of science knowledge of the Mars, Phobos/Deimos system, exploration risk mitigation, technology development, and public interest.

    The Large Synoptic Survey Telescope (LSST) will continuously image the entire sky visible from Cerro Pachon in northern Chile every 3-4 nights throughout the year. The LSST will provide data for a broad range of science investigations that require better than 1% photometric precision across the sky (repeatability and uniformity) and a similar accuracy of measured broadband color. The fast and persistent cadence of the LSST survey will significantly improve the temporal sampling rate with which celestial events and motions are tracked. To achieve these goals, and to optimally utilize the observing calendar, it will be necessary to obtain excellent photometric calibration of data taken over a wide range of observing conditions - even those not normally considered 'photometric'. To achieve this it will be necessary to routinely and accurately measure the full optical passband that includes the atmosphere as well as the instrumental telescope and camera system. The LSST mountain facility will include a new monochromatic dome illumination projector system to measure the detailed wavelength dependence of the instrumental passband for each channel in the system. The facility will also include an auxiliary spectroscopic telescope dedicated to measurement of atmospheric transparency at all locations in the sky during LSST observing. In this paper, we describe these systems and present laboratory and observational data that illustrate their performance.

    The burden of chronic respiratory disease (CRD) is alarming. International studies suggest that women with CRD are undersurveyed and underdiagnosed by physicians worldwide. It is unclear what the prevalence of CRD is in the general population of Syria, particularly among women, since there has never been a survey on CRD in this nation. The purpose of this study was to investigate the impact of different patterns of smoking on CRD in women. We extracted data on smoking patterns and outcome in women from the Global Alliance Against Chronic Respiratory Diseases survey. Using spirometric measurements before and after the use of inhaled bronchodilators, we tracked the frequency of CRD in females active and passive narghile or cigarette smokers presenting to primary care. We administered the questionnaire to 788 randomly selected females seen during 1 week in the fiscal year 2009-2010 in 22 primary care centers in six different regions of Syria. Inclusion criteria were age >6 years, presenting for any medical complaint. In this cross-sectional study, three groups of female subjects were evaluated: active smokers of cigarettes, active smokers of narghiles, and passive smokers of either cigarettes or narghiles. These three groups were compared to a control group of female subjects not exposed to active or passive smoking. Exposure to active cigarette smoke but not narghile smoke was associated with doctor-diagnosed chronic obstructive pulmonary disease (COPD). However, neither cigarette nor narghile active smoking was associated with increased incidence of spirometrically diagnosed COPD.

    The Geostationary Trace gas and Aerosol Sensor Optimization (GeoTASO) and the GEO-CAPE Airborne Simulator (GCAS) instruments are pushbroom sensors capable of making remote sensing measurements of air quality and ocean color. Originally developed as test-bed instruments for the Geostationary Coastal and Air Pollution Events (GEO-CAPE) decadal survey, these instruments are now also part of risk reduction for the upcoming Tropospheric Emissions: Monitoring of Pollution (TEMPO) and Geostationary Environment Monitoring Spectrometer (GEMS) geostationary satellite missions, and will provide validation capabilities after the satellite instruments are in orbit. GeoTASO and GCAS flew on two different aircraft in their first intensive air quality field campaigns during the DISCOVER-AQ missions over Texas in 2013 and Colorado in 2014. GeoTASO was also deployed in 2016 during the KORUS-AQ field campaign to make measurements of trace gases and aerosols over Korea. GeoTASO and GCAS collect spectra of backscattered solar radiation in the UV and visible that can be used to derive 2-D maps of trace gas columns below the aircraft at spatial resolutions on the order of 250 x 500 m. We present spatially resolved maps of trace gas retrievals of ozone, nitrogen dioxide, formaldehyde and sulfur dioxide over urban areas and power plants from flights during the field campaigns, and comparisons with data from ground-based spectrometers, in situ monitoring instruments, and satellites.

    1997-05-01

    A 20-MeV, 100-mA-CW proton-accelerator, Low Energy Development Accelerator (LEDA), is presently being developed, fabricated, and tested at Los Alamos National Laboratory. The beam diagnostics instrumentation for LEDA and the final 1700-GeV Accelerator Production of Tritium (APT), may be classified into two categories: operational and characterization instrumentation. The operational instrumentation for both facilities must not intercept the beam and must be sufficiently prompt and robust to provide accurate information to the operators and commissioners during full-current CW beam operation. The characterization instrumentation, primarily utilized during commissioning project-phases and off-normal tuning procedures, operate under more traditional 100-mA-peak and approximately 0.1-mA-average beam-current conditions. This paper will review some of the LEDA operational and characterization beam diagnostics instrumentation.

  20. Intonation and Compensation of Fretted String Instruments

    CERN Document Server

    Varieschi, Gabriele U

    2009-01-01

    In this paper we present mathematical models and we analyze the physics related to the problem of intonation of musical instruments such as guitars, mandolins and similar, i.e., we study how to produce perfectly in tune notes on these instruments. This analysis begins with the correct fret placement on the instrument fingerboard, following precise mathematical laws, but then it becomes increasingly complicated due to the geometrical deformation of the strings when these instruments are played, and also due to the inharmonic characteristics of the same strings. As a consequence of these factors, perfect intonation of all the notes on the instrument can never be achieved, but complex compensation procedures are introduced and studied to minimize the problem. To test the validity of these compensation procedures, we have performed extensive measurements using standard monochord sonometers and other basic acoustical devices, which confirm the correctness of our theoretical models. In particular, these experimenta...

    Full Text Available Security breaches are largely caused by the vulnerable software. Since individuals and organizations mostly depend on softwares, it is important to produce in secured manner. The first step towards producing secured software is through gathering security requirements. This paper describes Software Security Requirements Gathering Instrument (SSRGI that helps gather security requirements from the various stakeholders. This will guide the developers to gather security requirements along with the functional requirements and further incorporate security during other phases of software development. We subsequently present case studies that describe the integration of the SSRGI instrument with Software Requirements Specification (SRS document as specified in standard IEEE 830-1998. Proposed SSRGI will support the software developers in gathering security requirements in detail during requirements gathering phase.

    2014-06-01

    Now that the field of performing arts medicine has been in existence for over three decades, we are approaching a key point: we should start to see more articles that bring together the data that have been collected from several studies in order to draw more robust conclusions. Review articles and their more structured relative, the meta-analysis, can help to improve our understanding of a particular topic, comparing and synthesizing the results of previous research that has been done on that subject area. One way this could be done would be to review the research that has been carried out on the performance-related problems associated with playing a particular instrument or group of instruments. While I am not going to do that myself, I hope that others will. In this editorial, I will do a very selective review of the playing-related musculoskeletal disorders (PRMDs) associated with one instrument group (the keyboard instruments), focusing on the most played instrument in that group (the piano;).

    2004-01-01

    The objective of this review was to identify health-related workplace productivity loss survey instruments, with particular emphasis on those that capture a metric suitable for direct translation into a monetary figure. A literature search using Medline, HealthSTAR, PsycINFO and Econlit databases between 1966 and 2002, and a telephone-administered survey of business leaders and researchers, were conducted to identify health-related workplace productivity measurement survey instruments. This review was conducted from the societal perspective. Each identified instrument was reviewed for the following: (i). reliability; (ii). content validity; (iii). construct validity; (iv). criterion validity; (v). productivity metric(s); (vi). instrument scoring technique; (vii). suitability for direct translation into a monetary figure; (viii). number of items; (ix). mode(s) of administration; and (x). disease state(s) in which it had been tested. Reliability and validity testing have been performed for 8 of the 11 identified surveys. Of the 11 instruments identified, six captured metrics that are suitable for direct translation into a monetary figure. Of those six, one instrument measured absenteeism, while the other five measured both absenteeism and presenteeism. All of the identified instruments except for one were available as paper, self-administered questionnaires and many were available in languages other than English. This review provides a comprehensive overview of the published, peer-reviewed survey instruments available to measure health-related workplace productivity loss. As the field of productivity measurement matures, tools may be developed that will allow researchers to accurately calculate lost productivity costs when performing cost-effectiveness and cost-benefit analyses. Using data captured by these instruments, society and healthcare decision makers will be able to make better informed decisions concerning the value of the medications, disease management and

    In addition to being mandatory, the radiometric survey is a necessity, especially in the Brazilian reality with the construction of smaller and smaller rooms. However, calibration conditions, the instrumentation and its use, can produce underestimated factors. Measures made at Labprosaud/IFBA, with five different instruments and the ISO N 25 radiation quality, show the possibility of the values presented in the radiometric surveys are underestimated by up to 10 times. The results indicate the need for meters to be calibrated in ISO N qualities, in mammography energy range, in integrated dose mode and exposure times shorter or equal to 1 s. (author)

    The Aethalometer is an instrument that provides a real-time readout of the concentration of “Black” or “Elemental” carbon aerosol particles (BC or E) in an air stream (see Figure 1 and Figure 2). It is a self-contained instrument that measures the rate of change of optical transmission through a spot on a filter where aerosol is being continuously collected and uses the information to calculate the concentration of optically absorbing material in the sampled air stream. The instrument measures the transmitted light intensities through the “sensing” portion of the filter, on which the aerosol spot is being collected, and a “reference” portion of the filter as a check on the stability of the optical source. A mass flowmeter monitors the sample air flow rate. The data from these three measurements is used to determine the mean BC content of the air stream.

    An electronics circuit which provides for the recording of instrumentation data on an optical disk is disclosed. The optical disk is formatted in a spiral format instead of concentric tracks. The spiral format allows data to be recorded without the gaps that would be associated with concentric tracks. The instrumentation system provides each channel with a program instrumentation amplifier, a six pole lowpass switched capacitor filter, a sample and hold amplifier, and a digital to analog converter to provide automatic offset capability. Since each channel has its own components, simultaneous samples of every channel can be captured. All of the input signal's channel variables can be captured. All of the input signal's channel variables can be changed under software control without hardware changes. A single board computer is used for a system controller.

    Full Text Available The rules laid down by Romanian Capital Market Law and the regulations put in force for its implementation apply to issuers of financial instruments admitted to trading on the regulated market established in Romania. But the issuers remain companies incorporated under Company Law of 1990. Such dual regulations need increased attention in order to observe the legal status of the issuers/companies and financial instruments/shares. Romanian legislator has chosen to implement in Capital Market Law special rules regarding the administration of the issuers of financial instruments, not only rules regarding admitting and maintaining to a regulated market. Thus issuers are, in Romanian Law perspective, special company that should comply special rule regarding board of administration and general shareholders meeting.

  13. Virtual Sensor Test Instrumentation

    Wang, Roy

    2011-01-01

    Virtual Sensor Test Instrumentation is based on the concept of smart sensor technology for testing with intelligence needed to perform sell-diagnosis of health, and to participate in a hierarchy of health determination at sensor, process, and system levels. A virtual sensor test instrumentation consists of five elements: (1) a common sensor interface, (2) microprocessor, (3) wireless interface, (4) signal conditioning and ADC/DAC (analog-to-digital conversion/ digital-to-analog conversion), and (5) onboard EEPROM (electrically erasable programmable read-only memory) for metadata storage and executable software to create powerful, scalable, reconfigurable, and reliable embedded and distributed test instruments. In order to maximize the efficient data conversion through the smart sensor node, plug-and-play functionality is required to interface with traditional sensors to enhance their identity and capabilities for data processing and communications. Virtual sensor test instrumentation can be accessible wirelessly via a Network Capable Application Processor (NCAP) or a Smart Transducer Interlace Module (STIM) that may be managed under real-time rule engines for mission-critical applications. The transducer senses the physical quantity being measured and converts it into an electrical signal. The signal is fed to an A/D converter, and is ready for use by the processor to execute functional transformation based on the sensor characteristics stored in a Transducer Electronic Data Sheet (TEDS). Virtual sensor test instrumentation is built upon an open-system architecture with standardized protocol modules/stacks to interface with industry standards and commonly used software. One major benefit for deploying the virtual sensor test instrumentation is the ability, through a plug-and-play common interface, to convert raw sensor data in either analog or digital form, to an IEEE 1451 standard-based smart sensor, which has instructions to program sensors for a wide variety of

    The Kiso Supernova Survey (KISS) is a high-cadence optical wide-field supernova (SN) survey. The primary goal of the survey is to catch the very early light of a SN, during the shock breakout phase. Detection of SN shock breakouts combined with multi-band photometry obtained with other facilities would provide detailed physical information on the progenitor stars of SNe. The survey is performed using a 2.2x2.2 deg field-of-view instrument on the 1.05-m Kiso Schmidt telescope, the Kiso Wide Field Camera (KWFC). We take a three-minute exposure in g-band once every hour in our survey, reaching magnitude g~20-21. About 100 nights of telescope time per year have been spent on the survey since April 2012. The number of the shock breakout detections is estimated to be of order of 1 during our 3-year project. This paper summarizes the KISS project including the KWFC observing setup, the survey strategy, the data reduction system, and CBET-reported SNe discovered so far by KISS.

  19. Spectroelectrochemical Instrument Measures TOC

    Science.gov (United States)

    Kounaves, Sam

    2011-01-01

    A spectroelectrochemical instrument has been developed for measuring the total organic carbon (TOC) content of an aqueous solution. Measurements of TOC are frequently performed in environmental, clinical, and industrial settings. Until now, techniques for performing such measurements have included, various ly, the use of hazardous reagents, ultraviolet light, or ovens, to promote reactions in which the carbon contents are oxidized. The instrument now being developed is intended to be a safer, more economical means of oxidizing organic carbon and determining the TOC levels of aqueous solutions and for providing a low power/mass unit for use in planetary missions.

    This group of figurines, each 0.15m tall, were unearthed from a Tang Dynasty tomb in Changsha in 1977. Music was very developed in the Tang Dynasty. Colorful musical instruments and dances were popular both among the people and in the palace. These vivid-looking figurines wear pleated skirts with small sleeves and open chest, a style influenced by the non-Han nationalities living in the north and west of China. Some of the musical instruments were brought from the Western Regions. The figurines are playing the xiao (a vertical bamboo flute), the konghou (an

International studies suggest that women with CRD are undersurveyed and underdiagnosed by physicians worldwide. It is unclear what the prevalence of CRD is in the general population of Syria, particularly among women, since there has never been a survey on CRD in this nation. The purpose of this study was to investigate the impact of different patterns of smoking on CRD in women. Materials and methods: We extracted data on smoking patterns and outcome in women from the Global Alliance Against Chronic Respiratory Diseases survey. Using spirometric measurements before and after the use of inhaled bronchodilators, we tracked the frequency of CRD in females active and passive narghile or cigarette smokers presenting to primary care. We administered the questionnaire to 788 randomly selected females seen during 1 week in the fiscal year 2009–2010 in 22 primary care centers in six different regions of Syria. Inclusion criteria were age >6 years, presenting for any medical complaint. In this cross-sectional study, three groups of female subjects were evaluated: active smokers of cigarettes, active smokers of narghiles, and passive smokers of either cigarettes or narghiles

    2009-01-01

    The Spitzer Deep, Wide-Field Survey (SDWFS) is a four-epoch infrared survey of ten square degrees in the Bootes field of the NOAO Deep Wide-Field Survey using the IRAC instrument on the Spitzer Space Telescope. SDWFS, a Cycle four Spitzer Legacy project, occupies a unique position in the area-depth survey space defined by other Spitzer surveys. The four epochs that make up SDWFS permit -- for the first time -- the selection of infrared-variable and high proper motion objects over a wide field on timescales of years. Because of its large survey volume, SDWFS is sensitive to galaxies out to z~3 with relatively little impact from cosmic variance for all but the richest systems. The SDWFS datasets will thus be especially useful for characterizing galaxy evolution beyond z~1.5. This paper explains the SDWFS observing strategy and data processing, presents the SDWFS mosaics and source catalogs, and discusses some early scientific findings. The publicly-released, full-depth catalogs contain 6.78, 5.23, 1.20, and 0.9...

    2010-01-01

    This slide presentation reviews the results of a study on the use of wireless instrumentation and sensors on future launch vehicles. The use of wireless technologies would if feasible would allow for fewer wires, and allow for more flexibility. However, it was generally concluded that wireless solutions are not currently ready to replace wired technologies for launch vehicles. The recommendations of the study were to continue to use wired sensors as the primary choice for vehicle instrumentation, and to continue to assess needs and use wireless instrumentation where appropriate. The future work includes support efforts for wireless technologies, and continue to monitor the development of wireless solutions.

    1994-12-31

    In the October 1994 round of proposals at the ILL, the external biology review sub- committee was asked to allocate neutron beam time to a wide range of experiments, on almost half the total number of scheduled neutron instruments: on 3 diffractometers, on 3 small angle scattering instruments, and on some 6 inelastic scattering spectrometers. In the 3.5 years since the temporary reactor shutdown, the ILL`s management structure has been optimized, budgets and staff have been trimmed, the ILL reactor has been re-built, and many of the instruments up-graded, many powerful (mainly Unix) workstations have been introduced, and the neighboring European Synchrotron Radiation Facility has established itself as the leading synchrotron radiation source and has started its official user program. The ILL reactor remains the world`s most intense dedicated neutron source. In this challenging context, it is of interest to review briefly the park of ILL instruments used to study the structure and energetics of small and large biological systems. A brief summary will be made of each class of experiments actually proposed in the latest ILL proposal round.

    Uin, J. [Brookhaven National Lab. (BNL), Upton, NY (United States)

    2016-03-01

    The Integrating Nephelometer (Figure 1) is an instrument that measures aerosol light scattering. It measures aerosol optical scattering properties by detecting (with a wide angular integration – from 7 to 170°) the light scattered by the aerosol and subtracting the light scattered by the carrier gas, the instrument walls and the background noise in the detector (zeroing). Zeroing is typically performed for 5 minutes every day at midnight UTC. The scattered light is split into red (700 nm), green (550 nm), and blue (450 nm) wavelengths and captured by three photomultiplier tubes. The instrument can measure total scatter as well as backscatter only (from 90 to 170°) (Heintzenberg and Charlson 1996; Anderson et al. 1996; Anderson and Ogren 1998; TSI 3563 2015) At ARM (Atmospheric Radiation Measurement), two identical Nephelometers are usually run in series with a sample relative humidity (RH) conditioner between them. This is possible because Nephelometer sampling is non-destructive and the sample can be passed on to another instrument. The sample RH conditioner scans through multiple RH values in cycles, treating the sample. This kind of setup allows to study how aerosol particles’ light scattering properties are affected by humidification (Anderson et al. 1996). For historical reasons, the two Nephelometers in this setup are labeled “wet” and “dry”, with the “dry” Nephelometer usually being the one before the conditioner and sampling ambient air (the names are switched for the MAOS measurement site due to the high RH of the ambient air).

  3. High resolution tomographic instrument development

    1992-08-01

    Our recent work has concentrated on the development of high-resolution PET instrumentation reflecting in part the growing importance of PET in nuclear medicine imaging. We have developed a number of positron imaging instruments and have the distinction that every instrument has been placed in operation and has had an extensive history of application for basic research and clinical study. The present program is a logical continuation of these earlier successes. PCR-I, a single ring positron tomograph was the first demonstration of analog coding using BGO. It employed 4 mm detectors and is currently being used for a wide range of biological studies. These are of immense importance in guiding the direction for future instruments. In particular, PCR-II, a volume sensitive positron tomograph with 3 mm spatial resolution has benefited greatly from the studies using PCR-I. PCR-II is currently in the final stages of assembly and testing and will shortly be placed in operation for imaging phantoms, animals and ultimately humans. Perhaps the most important finding resulting from our previous study is that resolution and sensitivity must be carefully balanced to achieve a practical high resolution system. PCR-II has been designed to have the detection characteristics required to achieve 3 mm resolution in human brain under practical imaging situations. The development of algorithms by the group headed by Dr. Chesler is based on a long history of prior study including his joint work with Drs. Pelc and Reiderer and Stearns. This body of expertise will be applied to the processing of data from PCR-II when it becomes operational.

    Netherlands Hydrological Modeling Instrument A decision support system for water basin management. J.C. Hoogewoud , W.J. de Lange ,A. Veldhuizen , G. Prinsen , The Netherlands Hydrological modeling Instrument (NHI) is the center point of a framework of models, to coherently model the hydrological system and the multitude of functions it supports. Dutch hydrological institutes Deltares, Alterra, Netherlands Environmental Assessment Agency, RWS Waterdienst, STOWA and Vewin are cooperating in enhancing the NHI for adequate decision support. The instrument is used by three different ministries involved in national water policy matters, for instance the WFD, drought management, manure policy and climate change issues. The basis of the modeling instrument is a state-of-the-art on-line coupling of the groundwater system (MODFLOW), the unsaturated zone (metaSWAP) and the surface water system (MOZART-DM). It brings together hydro(geo)logical processes from the column to the basin scale, ranging from 250x250m plots to the river Rhine and includes salt water flow. The NHI is validated with an eight year run (1998-2006) with dry and wet periods. For this run different parts of the hydrology have been compared with measurements. For instance, water demands in dry periods (e.g. for irrigation), discharges at outlets, groundwater levels and evaporation. A validation alone is not enough to get support from stakeholders. Involvement from stakeholders in the modeling process is needed. There fore to gain sufficient support and trust in the instrument on different (policy) levels a couple of actions have been taken: 1. a transparent evaluation of modeling-results has been set up 2. an extensive program is running to cooperate with regional waterboards and suppliers of drinking water in improving the NHI 3. sharing (hydrological) data via newly setup Modeling Database for local and national models 4.

    Only little information is available on health-related quality of life (HRQoL) and its changes during the course of a normal pregnancy. We studied changes in HRQoL in a pregnant population during pregnancy and until 1 year postpartum in different body mass index (BMI) groups. Seven hundred and fifty pregnant women attending the first ultrasound examination before gestational week 14 were invited to participate in a longitudinal, communal-based survey. The participants were divided into three groups according to their BMI; <25, 25-29.9, and ≥30 kg/m(2) . The women were asked to fill in questionnaires assessing HRQoL (15D), depressive symptoms (Edinburgh Depression Scale, EPDS), medical, obstetric and socioeconomic status at baseline. HRQoL and EPDS were re-assessed at 30 weeks of gestation, and 6 weeks, 3 and 12 months postpartum. Of the invited 750 mothers, 325 (43%) returned the questionnaires and at least one follow-up questionnaire. At baseline, mean 15D scores decreased with increasing BMI but the difference was not statistically significant when adjusted for age, educational attainment, parity or EPDS-scores (0.929, 0.921 and 0.916, p = 0.16). During the course of pregnancy, the HRQoL of all women decreased but this decrease was significantly greater in the obese group (-0.088; 95% CI -0.110 to -0.065) than in the other groups [-0.054 (95% CI -0.062 to -0.045) and -0.051 (95% CI -0.068 to -0.033), p = 0.019]. Within 3 months postpartum the mean HRQoL recovered in all BMI groups to baseline levels, irrespective of the mode of delivery or pregnancy-related complications. The burden of pregnancy is heavier for the heaviest. © 2016 Nordic Federation of Societies of Obstetrics and Gynecology.

    2011-01-01

    Full Text Available Instruments of promotion as a part of marketing mix are usually associated with companies but more and more countries use this instrument in order to boost their exports. These foreign trade promotion instruments are now popular in many countries in the world since their use is not opposed to any World Trade Organization rules. Marketing instruments of trade promotions are the most important. They include National Exhibitions and National labels of origin and quality. In order to coordinate the application of these instruments countries have established national bodies for trade promotion. Many studies in the past had argued that national Agencies established to promote export did not had any real success, but recent studies indicate that they could have a significant impact on country export promotion. The result of this rise in impact of national export promotion agencies is due to international effort spearheaded by International Trade Center. The aim of this paper is to point out types and methods of marketing instruments application in trade promotion and to present the effectiveness of these instruments applications.

    1980-01-01

    The physician has, for whatever reasons, diminished his or her level of involvement on the team dedicated to developing, refining, and evaluating medical technology. As a result, the challenge confronting the physician and the technology development team today is to orchestrate a team structure that will ensure the greatest input and commitment from physicians and other professionals during current and future technology development. The charges of cost escalation and dehumanization in our system of health care delivery will also be discussed, as will the lack of, or confusion about, access to data concerning cost of a given instrument, and fuzzy semantics and perspectives on technology and instrumentation. The author suggests answers to, or means to ameliorate, the problems.

    Fiber optic sensing technology has emerged in recent years offering tremendous advantages over conventional aircraft instrumentation systems. The advantages of fiber optic sensors over their conventional counterparts are well established; they are lighter, smaller, and can provide enormous numbers of measurements at a fraction of the total sensor weight. After a brief overview of conventional and fiber-optic sensing technology, this paper presents an overview of the research that has been conducted at NASA Dryden Flight Research Center in recent years to advance this promising new technology. Research and development areas include system and algorithm development, sensor characterization and attachment, and real-time experimentally-derived parameter monitoring for ground- and flight-based applications. The vision of fiber optic smart structure technology is presented and its potential benefits to aerospace vehicles throughout the lifecycle, from preliminary design to final retirement, are presented.

    2011-06-01

    We describe the design of an instrument that can fully implement a new nanopatterning method called ice lithography, where ice is used as the resist. Water vapor is introduced into a scanning electron microscope (SEM) vacuum chamber above a sample cooled down to 110 K. The vapor condenses, covering the sample with an amorphous layer of ice. To form a lift-off mask, ice is removed by the SEM electron beam (e-beam) guided by an e-beam lithography system. Without breaking vacuum, the sample with the ice mask is then transferred into a metal deposition chamber where metals are deposited by sputtering. The cold sample is then unloaded from the vacuum system and immersed in isopropanol at room temperature. As the ice melts, metal deposited on the ice disperses while the metals deposited on the sample where the ice had been removed by the e-beam remains. The instrument combines a high beam-current thermal field emission SEM fitted with an e-beam lithography system, cryogenic systems, and a high vacuum metal deposition system in a design that optimizes ice lithography for high throughput nanodevice fabrication. The nanoscale capability of the instrument is demonstrated with the fabrication of nanoscale metal lines.

    One of the tasks specified in the NASA Langley controlled impact demonstration (CID) work package was to furnish dynamic instrumentation sensors. The types of instrumentation sensors required were accelerometers for aircraft structural loads measurements, seat belt load cells to measure anthropomorphic dummy responses to the aircraft impact, and strain gage bending bridges to measure the aircraft fuselage and wing bending during impact. The objective in the selection of dynamic instrumentation for the CID was to provide 352 of the highest quality transducers and remain within budget allocation. The transducers that were selected for the CID evaluation process were each subjected to rigorous laboratory acceptance tests and to aircraft fuselage section drop tests at the LaRC Impact Dynamics Research Facility. Data compiled from this series of tests showed the selected transducers to be best suited for the CID mission requirement. The transducers installation technique on the airframe proved successful. The transducer quality assurance was guaranteed through rigorous acceptance testing. Data acquired was 97.0%.

    An overview of the current status of the science instruments for the Thirty Meter Telescope is presented. Three first-light instruments as well as a science calibration unit for AO-assisted instruments are under development. Developing instrument collaborations that can design and build these challenging instruments remains an area of intense activity. In addition to the instruments themselves, a preliminary design for a facility cryogenic cooling system based on gaseous helium turbine expanders has been completed. This system can deliver a total of 2.4 kilowatts of cooling power at 65K to the instruments with essentially no vibrations. Finally, the process for developing future instruments beyond first light has been extensively discussed and will get under way in early 2017.

  11. INTELLIGENT VIRTUAL CONTROL:MEASURING INSTRUMENT FROM WHOLE TO PART

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

    A new concept called intelligent virtual control (IVC), which can be driven by measuring functions, is put forward. This small "intelligent measurement instrument unit (IMIU)", carrying with functions of instrument, consists of different types of intelligent virtual instrument (IVI) through individual components together as building blocks and can be displayed directly on the computer screen. This is a new concept of measuring instrument, and also an important breakthrough after virtual instrument (VI). Virtual control makes instrument resources obtain further exploitation. It brings about a fundamental change to the design and manufacturing mode. The instrument therefore, can not only be produced directly inside a PC, but the product is involved in the "green product" system. So far, all the present digital instruments will grow to be replaced by intelligent control with green characteristics.

  12. FHR Process Instruments

    Holcomb, David Eugene [ORNL

    2015-01-01

    Fluoride salt-cooled High temperature Reactors (FHRs) are entering into early phase engineering development. Initial candidate technologies have been identified to measure all of the required process variables. The purpose of this paper is to describe the proposed measurement techniques in sufficient detail to enable assessment of the proposed instrumentation suite and to support development of the component technologies. This paper builds upon the instrumentation chapter of the recently published FHR technology development roadmap. Locating instruments outside of the intense core radiation and high-temperature fluoride salt environment significantly decreases their environmental tolerance requirements. Under operating conditions, FHR primary coolant salt is a transparent, low-vapor-pressure liquid. Consequently, FHRs can employ standoff optical measurements from above the salt pool to assess in-vessel conditions. For example, the core outlet temperature can be measured by observing the fuel s blackbody emission. Similarly, the intensity of the core s Cerenkov glow indicates the fission power level. Short-lived activation of the primary coolant provides another means for standoff measurements of process variables. The primary coolant flow and neutron flux can be measured using gamma spectroscopy along the primary coolant piping. FHR operation entails a number of process measurements. Reactor thermal power and core reactivity are the most significant variables for process control. Thermal power can be determined by measuring the primary coolant mass flow rate and temperature rise across the core. The leading candidate technologies for primary coolant temperature measurement are Au-Pt thermocouples and Johnson noise thermometry. Clamp-on ultrasonic flow measurement, that includes high-temperature tolerant standoffs, is a potential coolant flow measurement technique. Also, the salt redox condition will be monitored as an indicator of its corrosiveness. Both

    Oil and gas exploration and production in the Fort Worth Basin (FWB) in north Texas have accelerated in the last 10 years due to the success of unconventional gas production. Here, hydraulic fracturing wastewater is disposed via re-injection into deep wells that penetrate Ordovician carbonate formations. The rise in wastewater injection has coincided with a marked rise in earthquake rates, suggesting a causal relationship between industry practices and seismicity. Most studies addressing this relationship in intraplate regions like the FWB focus on current seismicity, which provides an a-posteriori assessment of the processes involved. 3D seismic reflection data contribute complementary information on the existence, distribution, orientation and long-term deformation history of faults that can potentially become reactivated by the injection process. Here we present new insights into the tectonic evolution of faults in the FWB using multiple 3D seismic reflection surveys in the basin, west of the Dallas Fort-Worth Metroplex, where high-volume wastewater injection wells have increased most significantly in number in the past few years. The datasets image with remarkable clarity the 3,300 m-thick sedimentary rocks of the basin, from the crystalline basement to the Cretaceous cover, with particular detail of the Paleozoic section. The data, interpreted using coincident and nearby wells to correlate seismic reflections with stratigraphic markers, allow us to identify faults, extract their orientation, length and displacements at several geologic time intervals, and therefore, reconstruct the long-term deformation history. Throughout the basin, the data show that all seismically detectable faults were active during the Mississippian and Pennsylvanian, but that displacement amounts drop below data resolution ( 7 m) in the post-Pennsylvanian deposits. These results indicate that faults have been inactive for at least the past 300 Ma, until the recent 2008 surge in

    Virtual instruments based on Monte-Carlo techniques are now integral part of novel instrumentation development and the existing codes (McSTAS and Vitess) are extensively used to define and optimise novel instrumental concepts. Neutron spectrometers, however, involve a large number of parameters and their optimisation is often a complex and tedious procedure. Artificial intelligence algorithms are proving increasingly useful in such situations. Here, we present an automatic, reliable and scalable numerical optimisation concept based on the canonical genetic algorithm (GA). The algorithm was used to optimise the 3D magnetic field profile of the NSE spectrometer SPAN, at the HMI. We discuss the potential of the GA which combined with the existing Monte-Carlo codes (Vitess, McSTAS, etc.) leads to a very powerful tool for automated global optimisation of a general neutron scattering instrument, avoiding local optimum configurations.

  16. Splinting for adaptation of musical instruments.

    Science.gov (United States)

    Boyette, Jennifer

    2005-01-01

    Classic instrument design does not always match the physical capacity of the musician, as instruments are often chosen because of the pleasing sound and not the ease of play. Devices that are commercially available to create a more ergonomic structure may not address the specific needs of a musician with a chronic condition. Through basic splinting of the musician with an injury, these physical stressors can be reduced, allowing the continuation of musical practice and performance. Appropriate design modification requires a solid understanding of upper extremity anatomy, splint design technique, and the biomechanic principles of playing the instrument. Through knowledge of music theory and appreciation, one may modify the instrument while protecting tonal flexibility, resonance, mechanical freedom, and sound quality. Two case studies present a range of splint design, from small to large, static to dynamic, and for congenital or chronic conditions.

    In a companion paper, we have reported a >5σ detection of degree scale B-mode polarization at 150 GHz by the Bicep2 experiment. Here we provide a detailed study of potential instrumental systematic contamination to that measurement. We focus extensively on spurious polarization that can potentially arise from beam imperfections. We present a heuristic classification of beam imperfections according to their symmetries and uniformities, and discuss how resulting contamination adds or cancels in maps that combine observations made at multiple orientations of the telescope about its boresight axis. We introduce a technique, which we call “deprojection,” for filtering the leading order beam-induced contamination from time-ordered data, and show that it reduces power in Bicep2's actual and null-test BB spectra consistent with predictions using high signal-to-noise beam shape measurements. We detail the simulation pipeline that we use to directly simulate instrumental systematics and the calibration data used as input to that pipeline. Finally, we present the constraints on BB contamination from individual sources of potential systematics. We find that systematics contribute BB power that is a factor of ∼10× below Bicep2's three-year statistical uncertainty, and negligible compared to the observed BB signal. The contribution to the best-fit tensor/scalar ratio is at a level equivalent to r = (3–6) × 10{sup −3}.

    2015-01-01

    Full Text Available Patient satisfaction surveys can be an interesting way to improve quality and discuss the concept of patient-centered care. This study aimed to conduct a systematic review of the validated patient satisfaction measurement instruments applied in healthcare. The systematic review searched the MEDLINE/PubMed, LILACS, SciELO, Scopus and Web of Knowledge. The search strategy used the terms: "Patient Satisfaction" AND "Patient centered care" AND "Healthcare survey OR Satisfaction questionnaire" AND "Psychometric properties". 37 studies were included and almost all studies showed that satisfaction is a multidimensional construct. In these studies, 34 different instruments were used and most surveys contained the dimension patient-healthcare professional interactions, physical environment and management process. The COSMIN score for methodological quality showed that most of them scored a good or fair average. We can conclude that there is not a gold standard instrument for patient satisfaction assessment but some dimensions are essential for this construct.

The spectra of 40 million galaxies over 14,000 sq deg will be measured during the life of the experiment. A new prime focus corrector for the KPNO Mayall telescope will deliver light to 5,000 fiber optic positioners. The fibers in turn feed ten broad-band spectrographs. We present the design details of the instrument mechanism control systems for the spectrographs. Each spectrograph has a stand-alone mechanism control box that operates the unit's four remotely-operated mechanisms (two shutters and two Hartmannn doors), and provides a suite of temperature and humidity sensors. Each control box is highly modular, and is operated by a dedicated on-board Linux computer to provide all of the control and monitoring functions. We describe our solution for integrating a number of network-connected devices within each unit spectrograph, and describe the basic software architecture.

    Kaukler, William

    2001-01-01

    The past year's contribution from Dr. Kaukler's experimental effort consists of these 5 parts: a) Construction and proof-of-concept testing of a novel shearing plate viscometer designed to produce small shear rates and operate at elevated temperatures; b) Preparing nonlinear polymeric materials to serve as standards of nonlinear Theological behavior; c) Measurements and evaluation of above materials for nonlinear rheometric behavior at room temperature using commercial spinning cone and plate viscometers available in the lab; d) Preparing specimens from various forms of pitch for quantitative comparative testing in a Dynamic Mechanical Analyzer, Thermal Mechanical Analyzer; and Archeological Analyzer; e) Arranging to have sets of pitch specimens tested using the various instruments listed above, from different manufacturers, to form a baseline of the viscosity variation with temperature using the different test modes offered by these instruments by compiling the data collected from the various test results. Our focus in this project is the shear thinning behavior of ZBLAN glass over a wide range of temperature. Experimentally, there are no standard techniques to perform such measurements on glasses, particularly at elevated temperatures. Literature reviews to date have shown that shear thinning in certain glasses appears to occur, but no data is available for ZBLAN glass. The best techniques to find shear thinning behavior require the application of very low rates of shear. In addition, because the onset of the thinning behavior occurs at an unknown elevated temperature, the instruments used in this study must provide controlled low rates of shear and do so for temperatures approaching 600 C. In this regard, a novel shearing parallel plate viscometer was designed and a prototype built and tested.

    2011-01-01

    More than 700 exoplanets have been discovered and studied using indirect techniques, leading our field into the exciting new era of comparative exoplanetology. However, the direct detection of exoplanetary systems still remains at the sensitivity limits of both ground- and space-based observatories. The development of new technologies for adaptive optics systems and high contrast instruments continues to increase the ability to directly study exoplanets. The scientific impact of these developments has promising prospects for both short and long timescales. In my talk, I will discuss recent highlights from the SEEDS survey and the current instrumentation in use at the Subaru telescope. SEEDS is a high contrast imaging strategic observing program with 120 nights of time allocated at the NAOJ's flagship optical and infrared telescope. I will also describe new instrumentation I designed to improve the SEEDS capabilities and efficiency. Finally, I will briefly discuss the conceptual design of a transiting planet camera to fly as a potential second generation instrument on-board NASA's SOFIA observatory.

    Harper, Stuart E; Battye, Richard; Olivari, Lucas

    2016-01-01

    It has been proposed recently that the SKA1-MID could be used to conduct an HI intensity mapping survey that could rival upcoming Stage IV dark energy surveys. However, measuring the weak HI signal is expected to be very challenging due to contaminations such as residual Galactic emission, RFI, and instrumental 1/f noise. Modelling the effects of these contaminants on the cosmological HI signal requires numerical end-to-end simulations. Here we present how 1/f noise within the receiver can double the effective uncertainty of an SKA-like survey to HI on large angular scales (l < 50).

  11. SCUBA-2 instrument: an application of large-format superconducting bolometer arrays for submillimetre astronomy

    Science.gov (United States)

    Hollister, Matthew Ian

    2009-01-01

    This thesis concerns technical aspects related to the design and operation of the submillimetre common-user bolometer array 2 (SCUBA-2) instrument, a new wide-field camera for submillimetre astronomy currently undergoing commissioning on the James Clerk Maxwell Telescope on Mauna Kea, Hawaii. Offering unprecedented sensitivity and mapping capabilities, SCUBA-2 is expected to make a major impact in surveys of the sky at submillimetre wavelengths, a largely unexplored part of the electromagnetic spectrum, and provide better understanding of the formation and evolution of galaxies, stars and planets by providing large, unbiased samples of such objects. SCUBA-2 uses large arrays of bolometers, with superconducting transition edge sensors (TESs) as the temperature-sensitive element. TES devices are a relatively new technology, utilising the sharp resistance change between the normal and superconducting states to make a sensitive thermistor. Kilopixel arrays of such devices are multiplexed using superconducting quantum interference devices (SQUIDs). This thesis derives the key detector performance parameters, and presents analysis of engineering data to confirm the detector performance on array scales. A key issue for bolometric instruments for far infrared and submillimetre astronomy is the need to operate at extremely low temperatures in the sub-kelvin and millikelvin ranges to achieve the necessary detector sensitivity. This work describes the design, testing and performance of the liquid cryogen-free millikelvin cryostat, the first such instrument to be deployed for astronomy. Subsequent chapters detail the design and testing of a magnetic shielding scheme for the instrument, an important aspect of the operation of superconducting devices. Based on experience with the construction and testing of this instrument, a number of potential improvements for future instruments are presented and discussed.

    Through the use of multi-modal methods, the purpose of this study was to develop and assess measurement properties of an instrument evaluating specific sexual behaviors of college students and the role alcohol intoxication plays in one's intention to participate in these behaviors. A modified version of N. Krause's instrument development process was applied to create a behavior-specific instrument assessing oral, vaginal, and anal sex behaviors. The process included a review by expert scholars in relevant fields, cognitive interviews with the target population using screen-capture program Camtasia, piloting to assess measurement scales, and a formal investigation. The applied instrument development process employed screen capture software and web-based surveying in a cost-effective format suitable for mixed-method measurement development. The development and application of the instrument provides a clearer understanding of the relationship between alcohol use and sexual activity and aids in the development of effective public health interventions and policies.

    1978-01-01

    Think of guitars and you think of rock and country music, or the vigorous rhythms of the gypsy flamenco, or perhaps the classical strumming of a Segovia. About the last thing you would associate with guitars is aerospace technology. Yet there is a connection. A whole family of quality guitars is an outgrowth of helicopter rotor research conducted for the military services and NASA by an aerospace contractor. These musical spinoffs, commercially available and rapidly gaining in popularity, are the Ovation guitar line, manufactured by Ovation Instruments, Inc., Bloomfield, Connecticut. Ovation Instruments is a subsidiary of Kaman Corporation, a diversified company originally formed to develop and build helicopters. A helicopter's rotor system, with thousands of moving parts, is highly susceptible to vibration. For rotor efficiency, vibration must be "dampened," or reduced. Like other helicopter builders, Kaman Corporation spent years of research toward that end. The technology thus developed, together with the availability of staff experts in vibration engineering, sparked an idea in the mind of the company's president and founder, Charles H. Karnan. A guitarist of professional caliber, Kaman reasoned that vibration-dampening technology could be turned around to enhance vibration and thereby produce a guitar with superior sound.

    2012-07-01

    The Q/U Imaging ExperimenT (QUIET) is designed to measure polarization in the Cosmic Microwave Background, targeting the imprint of inflationary gravitational waves at large angular scales ({approx}1{sup o}). Between 2008 October and 2010 December, two independent receiver arrays were deployed sequentially on a 1.4m side-fed Dragonian telescope. The polarimeters which form the focal planes use a highly compact design based on High Electron Mobility Transistors (HEMTs) that provides simultaneous measurements of the Stokes parameters Q, U, and I in a single module. The 17-element Q-band polarimeter array, with a central frequency of 43.1 GHz, has the best sensitivity (69 {mu}Ks{sup 1/2}) and the lowest instrumental systematic errors ever achieved in this band, contributing to the tensor-to-scalar ratio at r < 0:1. The 84-element W-band polarimeter array has a sensitivity of 87 {mu}Ks{sup 1/2} at a central frequency of 94.5 GHz. It has the lowest systematic errors to date, contributing at r < 0:01. The two arrays together cover multipoles in the range {ell} {approx} 25 -- 975. These are the largest HEMT-based arrays deployed to date. This article describes the design, calibration, performance of, and sources of systematic error for the instrument.

    Sall, Ken; Ames, Troy; Warsaw, Craig; Koons, Lisa; Shafer, Richard

    1998-01-01

    The Instrument Remote Control (IRC) project ongoing at NASA's Goddard Space Flight Center's (GSFC) Information Systems Center (ISC) supports NASA's mission by defining an adaptive intranet-based framework that provides robust interactive and distributed control and monitoring of remote instruments. An astronomical IRC architecture that combines the platform-independent processing capabilities of Java with the power of Extensible Markup Language (XML) to express hierarchical data in an equally platform-independent, as well as human readable manner, has been developed. This architecture is implemented using a variety of XML support tools and Application Programming Interfaces (API) written in Java. IRC will enable trusted astronomers from around the world to easily access infrared instruments (e.g., telescopes, cameras, and spectrometers) located in remote, inhospitable environments, such as the South Pole, a high Chilean mountaintop, or an airborne observatory aboard a Boeing 747. Using IRC's frameworks, an astronomer or other scientist can easily define the type of onboard instrument, control the instrument remotely, and return monitoring data all through the intranet. The Astronomical Instrument Markup Language (AIML) is the first implementation of the more general Instrument Markup Language (IML). The key aspects of our approach to instrument description and control applies to many domains, from medical instruments to machine assembly lines. The concepts behind AIML apply equally well to the description and control of instruments in general. IRC enables us to apply our techniques to several instruments, preferably from different observatories.
