  5. Entropy Evaluation Based on Value Validity

    Directory of Open Access Journals (Sweden)

    Tarald O. Kvålseth

    2014-09-01

    Full Text Available Besides its importance in statistical physics and information theory, the Boltzmann-Shannon entropy S has become one of the most widely used and misused summary measures of various attributes (characteristics in diverse fields of study. It has also been the subject of extensive and perhaps excessive generalizations. This paper introduces the concept and criteria for value validity as a means of determining if an entropy takes on values that reasonably reflect the attribute being measured and that permit different types of comparisons to be made for different probability distributions. While neither S nor its relative entropy equivalent S* meet the value-validity conditions, certain power functions of S and S* do to a considerable extent. No parametric generalization offers any advantage over S in this regard. A measure based on Euclidean distances between probability distributions is introduced as a potential entropy that does comply fully with the value-validity requirements and its statistical inference procedure is discussed.

  6. [Self-deliverance or infanticide?].

    Science.gov (United States)

    Rittner, Christian; Gehb, Iris; Püschel, Klaus

    2008-01-01

    Self-deliverance by a woman in labour is nowadays a very rare event. The authors report the case of a 24-year-old primipara and a newborn of 49 cm length and 2484 g body weight with a complex pattern of injuries on the head, neck, shoulder and back who had breathed for at least 15 to 30 minutes after birth and died from massive craniocerebral trauma and lesions in the oral and cervical region. As one of the experts considered it possible that the skull fractures were exclusively due to the self-deliverance, the woman was acquitted of the charge of manslaughter. This hypothesis is critically discussed on the basis of the presumable course of the delivery and the literature.

  15. Predicting deliverability of volumetric-modulated arc therapy (VMAT) plans using aperture complexity analysis.

    Science.gov (United States)

    Younge, Kelly C; Roberts, Don; Janes, Lindsay A; Anderson, Carlos; Moran, Jean M; Matuszak, Martha M

    2016-07-08

    The purpose of this study was to evaluate the ability of an aperture complexity metric for volumetric-modulated arc therapy (VMAT) plans to predict plan delivery accuracy. We developed a complexity analysis tool as a plug-in script to Varian's Eclipse treatment planning system. This script reports the modulation of plans, arcs, and individual control points for VMAT plans using a previously developed complexity metric. The calculated complexities are compared to that of 649 VMAT plans previously treated at our institution from 2013 to mid-2015. We used the VMAT quality assurance (QA) results from the 649 treated plans, plus 62 plans that failed pretreatment QA, to validate the ability of the complexity metric to predict plan deliverability. We used a receiver operating characteristic (ROC) analysis to determine an appropriate complexity threshold value above which a plan should be considered for reoptimization before it moves further through our planning workflow. The average complexity metric for the 649 treated plans analyzed with the script was 0.132 mm-1 with a standard deviation of 0.036 mm-1. We found that when using a threshold complexity value of 0.180 mm-1, the true positive rate for correctly identifying plans that failed QA was 44%, and the false-positive rate was 7%. Used clinically with this threshold, the script can identify overly modulated plans and thus prevent a significant portion of QA failures. Reducing VMAT plan complexity has a number of important clinical benefits, including improving plan deliverability and reducing treatment time. Use of the complexity metric during both the planning and QA processes can reduce the number of QA failures and improve the quality of VMAT plans used for treatment.

  16. Supply chain integration scales validation and benchmark values

    Full Text Available Purpose: The clarification of the constructs of the supply chain integration (clients, suppliers, external and internal, the creation of a measurement instrument based on a list of items taken from earlier papers, the validation of these scales and a preliminary benchmark to interpret the scales by percentiles based on a set of control variables (size of the plant, country, sector and degree of vertical integration. Design/methodology/approach: Our empirical analysis is based on the HPM project database (2005-2007 timeframe. The international sample is made up of 266 plants across ten countries: Austria, Canada, Finland, Germany, Italy, Japan, Korea, Spain, Sweden and the USA. In each country. We analized the descriptive statistics, internal consistency testing to purify the items (inter-item correlations, Cronbach’s alpha, squared multiple correlation, corrected item-total correlation, exploratory factor analysis, and finally, a confirmatory factor analysis to check the convergent and discriminant validity of the scales. The analyses will be done with the SPSS and EQS programme using the maximum likelihood parameter estimation method. Findings: The four proposed scales show excellent psychometric properties. Research limitations/implications: with a clearer and more concise designation of the supply chain integration measurement scales more reliable and accurate data could be taken to analyse the relations between these constructs with other variables of interest to the academic l fields. Practical implications: providing scales that are valid as a diagnostic tool for best practices, as well as providing a benchmark with which to compare the score for each individual plant against a collection of industrial companies from the machinery, electronics and transportation sectors. Originality/value: supply chain integration may be a major factor in explaining the performance of companies. The results are nevertheless inconclusive, the vast range

    VALUE is an open European network to validate and compare downscaling methods for climate change research (http://www.value-cost.eu). A key deliverable of VALUE is the development of a systematic validation framework to enable the assessment and comparison of both dynamical and statistical downscaling methods. This framework is based on a user-focused validation tree, guiding the selection of relevant validation indices and performance measures for different aspects of the validation (marginal, temporal, spatial, multi-variable). Moreover, several experiments have been designed to isolate specific points in the downscaling procedure where problems may occur (assessment of intrinsic performance, effect of errors inherited from the global models, effect of non-stationarity, etc.). The list of downscaling experiments includes 1) cross-validation with perfect predictors, 2) GCM predictors -aligned with EURO-CORDEX experiment- and 3) pseudo reality predictors (see Maraun et al. 2015, Earth's Future, 3, doi:10.1002/2014EF000259, for more details). The results of these experiments are gathered, validated and publicly distributed through the VALUE validation portal, allowing for a comprehensive community-open downscaling intercomparison study. In this contribution we describe the overall results from Experiment 1), consisting of a European wide 5-fold cross-validation (with consecutive 6-year periods from 1979 to 2008) using predictors from ERA-Interim to downscale precipitation and temperatures (minimum and maximum) over a set of 86 ECA&D stations representative of the main geographical and climatic regions in Europe. As a result of the open call for contribution to this experiment (closed in Dec. 2015), over 40 methods representative of the main approaches (MOS and Perfect Prognosis, PP) and techniques (linear scaling, quantile mapping, analogs, weather typing, linear and generalized regression, weather generators, etc.) were submitted, including information both data

  7. The validity and value of inclusive fitness theory.

    Science.gov (United States)

    Bourke, Andrew F G

    2011-11-22

    Social evolution is a central topic in evolutionary biology, with the evolution of eusociality (societies with altruistic, non-reproductive helpers) representing a long-standing evolutionary conundrum. Recent critiques have questioned the validity of the leading theory for explaining social evolution and eusociality, namely inclusive fitness (kin selection) theory. I review recent and past literature to argue that these critiques do not succeed. Inclusive fitness theory has added fundamental insights to natural selection theory. These are the realization that selection on a gene for social behaviour depends on its effects on co-bearers, the explanation of social behaviours as unalike as altruism and selfishness using the same underlying parameters, and the explanation of within-group conflict in terms of non-coinciding inclusive fitness optima. A proposed alternative theory for eusocial evolution assumes mistakenly that workers' interests are subordinate to the queen's, contains no new elements and fails to make novel predictions. The haplodiploidy hypothesis has yet to be rigorously tested and positive relatedness within diploid eusocial societies supports inclusive fitness theory. The theory has made unique, falsifiable predictions that have been confirmed, and its evidence base is extensive and robust. Hence, inclusive fitness theory deserves to keep its position as the leading theory for social evolution.

  11. An Improved Fuzzy Based Missing Value Estimation in DNA Microarray Validated by Gene Ranking

    Directory of Open Access Journals (Sweden)

    Sujay Saha

    2016-01-01

    Full Text Available Most of the gene expression data analysis algorithms require the entire gene expression matrix without any missing values. Hence, it is necessary to devise methods which would impute missing data values accurately. There exist a number of imputation algorithms to estimate those missing values. This work starts with a microarray dataset containing multiple missing values. We first apply the modified version of the fuzzy theory based existing method LRFDVImpute to impute multiple missing values of time series gene expression data and then validate the result of imputation by genetic algorithm (GA based gene ranking methodology along with some regular statistical validation techniques, like RMSE method. Gene ranking, as far as our knowledge, has not been used yet to validate the result of missing value estimation. Firstly, the proposed method has been tested on the very popular Spellman dataset and results show that error margins have been drastically reduced compared to some previous works, which indirectly validates the statistical significance of the proposed method. Then it has been applied on four other 2-class benchmark datasets, like Colorectal Cancer tumours dataset (GDS4382, Breast Cancer dataset (GSE349-350, Prostate Cancer dataset, and DLBCL-FL (Leukaemia for both missing value estimation and ranking the genes, and the results show that the proposed method can reach 100% classification accuracy with very few dominant genes, which indirectly validates the biological significance of the proposed method.

    Yüksel GÜNDÜZ

    2012-04-01

    Full Text Available Aim of this study is to develop a valid and reliable scale that measure teachers’ ethical values according to students perceptions. The sampling of the research consisted of 617 students attending the elemantary schools 4, 5, 6 and 7th grades in the city of Artvin Center county in academic year of 2010-2011. In order to determine structural validity of scale, explanatory factor analysis procedure is applied by Varimax with Kaiser Normalization. Also, in order to determine criteria validity of Teachers’ Ethical Values Scale According to Student Perception, Adjective Check List (ACL test is applied. For calculation of scale reliability Cronbach-alpha internal coherence coefficient and test-retest calculations were made. After the explanatory and corroborant factor analysis, the scale consisted of 30 items and two dimentions. Internal coherence coefficient of the scale is .95 and test-retest correlation coefficient is .88. These values could be considered as an indication that this scale can perform a valid and reliable measurement of teachers’ ethical values.

    VALUE is an open European network to validate and compare downscaling methods for climate change research. Within VALUE a systematic validation framework to enable the assessment and comparison of both dynamical and statistical downscaling methods has been developed. In the first validation experiment the downscaling methods are validated in a setup with perfect predictors taken from the ERA-interim reanalysis for the period 1997 - 2008. This allows to investigate the isolated skill of downscaling methods without further error contributions from the large-scale predictors. One aspect of the validation is the representation of spatial variability. As part of the VALUE validation we have compared various properties of the spatial variability of downscaled daily temperature and precipitation with the corresponding properties in observations. We have used two test validation datasets, one European-wide set of 86 stations, and one higher-density network of 50 stations in Germany. Here we present results based on three approaches, namely the analysis of i.) correlation matrices, ii.) pairwise joint threshold exceedances, and iii.) regions of similar variability. We summarise the information contained in correlation matrices by calculating the dependence of the correlations on distance and deriving decorrelation lengths, as well as by determining the independent degrees of freedom. Probabilities for joint threshold exceedances and (where appropriate) non-exceedances are calculated for various user-relevant thresholds related for instance to extreme precipitation or frost and heat days. The dependence of these probabilities on distance is again characterised by calculating typical length scales that separate dependent from independent exceedances. Regionalisation is based on rotated Principal Component Analysis. The results indicate which downscaling methods are preferable if the dependency of variability at different locations is relevant for the user.

    (i) To develop the Pharmacy Value-Added Services Questionnaire (PVASQ) using emerging themes generated from interviews. (ii) To establish reliability and validity of questionnaire instrument. Using an extended Theory of Planned Behavior as the theoretical model, face-to-face interviews generated salient beliefs of pharmacy value-added services. The PVASQ was constructed initially in English incorporating important themes and later translated into the Malay language with forward and backward translation. Intention (INT) to adopt pharmacy value-added services is predicted by attitudes (ATT), subjective norms (SN), perceived behavioral control (PBC), knowledge and expectations. Using a 7-point Likert-type scale and a dichotomous scale, test-retest reliability (N=25) was assessed by administrating the questionnaire instrument twice at an interval of one week apart. Internal consistency was measured by Cronbach's alpha and construct validity between two administrations was assessed using the kappa statistic and the intraclass correlation coefficient (ICC). Confirmatory Factor Analysis, CFA (N=410) was conducted to assess construct validity of the PVASQ. The kappa coefficients indicate a moderate to almost perfect strength of agreement between test and retest. The ICC for all scales tested for intra-rater (test-retest) reliability was good. The overall Cronbach' s alpha (N=25) is 0.912 and 0.908 for the two time points. The result of CFA (N=410) showed most items loaded strongly and correctly into corresponding factors. Only one item was eliminated. This study is the first to develop and establish the reliability and validity of the Pharmacy Value-Added Services Questionnaire instrument using the Theory of Planned Behavior as the theoretical model. The translated Malay language version of PVASQ is reliable and valid to predict Malaysian patients' intention to adopt pharmacy value-added services to collect partial medicine supply.

J Strength Cond Res 30(11): 3007-3013, 2016-The aim of this study was to determine the validity of an accelerometer to measure average acceleration values during high-speed running. Thirteen subjects performed three sprint efforts over a 40-m distance (n = 39). Acceleration was measured using a 100-Hz triaxial accelerometer integrated within a wearable tracking device (SPI-HPU; GPSports). To provide a concurrent measure of acceleration, timing gates were positioned at 10-m intervals (0-40 m). Accelerometer data collected during 0-10 m and 10-20 m provided a measure of average acceleration values. Accelerometer data was recorded as the raw output and filtered by applying a 3-point moving average and a 10-point moving average. The accelerometer could not measure average acceleration values during high-speed running. The accelerometer significantly overestimated average acceleration values during both 0-10 m and 10-20 m, regardless of the data filtering technique (p < 0.001). Body mass significantly affected all accelerometer variables (p < 0.10, partial η = 0.091-0.219). Body mass and the absence of a gravity compensation formula affect the accuracy and practicality of accelerometers. Until GPSports-integrated accelerometers incorporate a gravity compensation formula, the usefulness of any accelerometer-derived algorithms is questionable.

    To study the impact of different smoothing parameters on IMRT plan quality and deliverabilityMethods: Five previously treated patients of carcinoma cervix were chosen. Planning target volume (PTV) and organ at risk (OAR) i.e. bladder and rectum were contoured. In each case, five different dynamic IMRT plans with 6MV photon beam were created in eclipse TPS for Varian 2300C/D linear accelerator. During optimization, dose volume constraints and priorities were kept constant and smoothing parameters were varied as follows: 10/5, 40/30 (TPS default value), 80/60, 100/80 and 200/150 in x/y direction. Total dose was 5040cGy in 28 fractions and prescribed at 95% isodose. Plan quality was analyzed by means of coverage index (CI=PTV covered by prescription dose/PTV), OAR mean doses and total monitor units (MUs) required to deliver a plan. In each case, deliverability of treatment plans were verified with I'matriXX ion-chamber array and compared with TPS dose-plane using gamma index of 3% dose difference and 3mm distance to agreement criteria. The CI values were 0.9435±0.032, 0.9418±0.034, 0.9380±0.041, 0.9330±0.047 and 0.8681±0.072 for 10/5, 40/30, 80/60, 100/80 and 200/150 in x/y direction. PTV dose maximum decreases with the increase of smoothing parameters and values were 5724.38±106.08 5723.30±131.60, 5708.44±1 16.74, 5697.92±116.82 and 5587.50±189.50cGy. The bladder mean doses were 4027.46±630.40, 3821.62±420.62, 3819.58±427.08, 3813.42±435.02 and 3814.78±438.0cGy. Rectum mean doses were 3839.88±466.02, 3835.52±473.18, 3837.52±472.88, 3839.10±471.20 and 3918.94±469.76cGy. Similarly, Total MUs were 1588±205, 1573±214, 1513±274, 1456±335 and 1219±68. Gamma pass rate increases with the increase of smoothing parameters and values were 99.16±0.21%, 99.07±0.19%, 99.24±0.28%, 99.29±0.29% and 99.75±0.15%.

    Full Text Available We present here a gas deliverability computational model for single reservoir with multi wells. The questions of how long the gas delivery can be sustained and how to estimate the plateau time are discussed here. In order to answer such a question, in this case, a coupling method which consists of material balance method and gas flow equation method is developed by assuming no water influx in the reservoir. Given the rate and the minimum pressure of gas at the processing plant, the gas pressure at the wellhead and at the bottom hole can be obtained. From here, the estimation of the gas deliverability can be done. In this paper we obtain a computational method which gives direct computation for pressure drop from the processing plant to the wells, taking into account different well behavior. Here AOF technique is used for obtaining gas rate in each well. Further Tian & Adewumi correlation is applied for pressure drop model along vertical and horizontal pipes and Runge-Kutta method is chosen to compute the well head and bottom hole pressures in each well which then being used to estimate the plateau times. We obtain here direct computational scheme of gas deliverability from reservoir to processing plant for single reservoir with multi-wells properties. Computational results give different profiles (i.e. gas rate, plateau and production time, etc for each well. Further by selecting proper flow rate reduction, the flow distribution after plateau time to sustain the delivery is computed for each well.

    Several organizations have developed frameworks to systematically assess the value of new drugs. To evaluate the convergent validity and interrater reliability of 4 value frameworks to understand the extent to which these tools can facilitate value-based treatment decisions in oncology. Eight panelists used the American Society of Clinical Oncology (ASCO), European Society for Medical Oncology (ESMO), Institute for Clinical and Economic Review (ICER), and National Comprehensive Cancer Network (NCCN) frameworks to conduct value assessments of 15 drugs for advanced lung and breast cancers and castration-refractory prostate cancer. Panelists received instructions and published clinical data required to complete the assessments, assigning each drug a numeric or letter score. Kendall's Coefficient of Concordance for Ranks (Kendall's W) was used to measure convergent validity by cancer type among the 4 frameworks. Intraclass correlation coefficients (ICCs) were used to measure interrater reliability for each framework across cancers. Panelists were surveyed on their experiences. Kendall's W across all 4 frameworks for breast, lung, and prostate cancer drugs was 0.560 (P= 0.010), 0.562 (P = 0.010), and 0.920 (P fair to excellent, increasing with clinical benefit subdomain concordance and simplicity of drug trial data. Interrater reliability, highest for ASCO and ESMO, improved with clarity of instructions and specificity of score definitions. Continued use, analyses, and refinements of these frameworks will bring us closer to the ultimate goal of using value-based treatment decisions to improve patient care and outcomes.

  9. Valuing structured professional judgment: predictive validity, decision-making, and the clinical-actuarial conflict.

    Falzer, Paul R

    2013-01-01

    Structured professional judgment (SPJ) has received considerable attention as an alternative to unstructured clinical judgment and actuarial assessment, and as a means of resolving their ongoing conflict. However, predictive validity studies have typically relied on receiver operating characteristic (ROC) analysis, the same technique commonly used to validate actuarial assessment tools. This paper presents SPJ as distinct from both unstructured clinical judgment and actuarial assessment. A key distinguishing feature of SPJ is the contribution of modifiable factors, either dynamic or protective, to summary risk ratings. With modifiable factors, the summary rating scheme serves as a prognostic model rather than a classification procedure. However, prognostic models require more extensive and thorough predictive validity testing than can be provided by ROC analysis. It is proposed that validation should include calibration and reclassification techniques, as well as additional measures of discrimination. Several techniques and measures are described and illustrated. The paper concludes by tracing the limitations of ROC analysis to its philosophical foundation and its origin as a statistical theory of decision-making. This foundation inhibits the performance of crucial tasks, such as determining the sufficiency of a risk assessment and examining the evidentiary value of statistical findings. The paper closes by noting a current effort to establish a viable and complementary relationship between SPJ and decision-making theory.

    The development of professional values is a significant factor in improving nursing practice. It is important to develop nursing curricula for establishing and investigating nursing students' professional values. Professional values of Korean nursing students may differ from those of nursing students in other countries, and research on the professional values of Koreans using a validated scale is needed. The purpose of this study was to test the validity and reliability of the Korean version of the Nursing Professional Values Scale-Revised. Convenience samples of 1077 baccalaureate nursing students were recruited from four universities in Korea. Construct validity and internal consistency reliability using explanatory factor analysis were examined. The validity was obtained using a principle component analysis of a five-factor structure (variance explained 58.90%). The five factors were labeled human dignity, professionalism, innovation, contribution, and advocacy. The Cronbach's alphas were .93 for the total scale and .89-.62 for the subscales. The overall Korean version of the Nursing Professional Values Scale-Revised was valid and reliable for measuring nursing professional values. Criterion-related validation of the Korean version of the Nursing Professional Values Scale-Revised and the development of items congruent with Korean culture are needed to support the validity and reliability of the Korean version of the Nursing Professional Values Scale-Revised.

    Digital breast tomosynthesis (DBT) is an emerging imaging modality that provides quasi-three-dimensional structural information of the breast and has strong promise to improve the differentiation of normal tissue and suspicious masses reducing the tissue overlaps. DBT images are reconstructed from a sequence of low-dose X-ray projections of the breast acquired at a small number of angles over a limited angular range. The Ho logic Selen ia Dimensions system is equipped with an amorphous Selenium (a-Se) detector layer of 250 μm thickness and a 70 μm pixel pitch. Studies are needed to determine the radiation dose of patients that are undergoing this emerging procedure to compare with the results obtained in DBT images. The mean glandular dose (D{sub G}) is the dosimetric quantity used in quality control of the mammographic systems. The aim of this work is to validate D{sub G} values for different breast thicknesses provided by a Ho logic Selen ia Dimensions system using a DBT mode in comparison with the same results obtained by a calibrated 90 X 5-6M-model Radcal ionization chamber. D{sub G} values were derived from the incident air kerma (K{sub i}) measurements and tabulated conversion coefficients that are dependent on the half value layer (HVL) of the X-ray spectrum. Voltage and tube loading values were recorded in irradiations using W/Al anode/filter combination, automatic exposure control mode and polymethyl methacrylate (PMMA) slabs which simulate different breast thicknesses. For K{sub i} measurements, the ionization chamber was positioned at 655 mm from the focus and the same radiographic technique values were selected with the manual mode. D{sub G} values for a complete procedure ranged from 0.9 ± 0.1 to 3.7 ± 0.4 mGy. The results for different breast thicknesses are in accordance with values obtained by DBT images and with acceptable levels established by the Commission of the European Communities (Cec) and the International Atomic Energy Agency (IAEA

    The Control of Allergic Rhinitis and Asthma Test for Children (CARATKids) assesses asthma and allergic rhinitis control in children younger than 12 years. To validate the Brazilian Portuguese version of the CARATKids and to define the cutoff values for identifying uncontrolled disease. Children aged 6 to 12 years with asthma and allergic rhinitis were studied (n = 102). CARATKids, childhood Asthma Control Test (cACT), total nasal symptom score (TNSS), and visual analog scale (VAS) scores were obtained at baseline and after 4 to 6 weeks. Internal consistency, test-retest reliability, responsiveness, and validity of the Brazilian CARATKids were assessed according to the Consensus-based Standards for the Selection of Health Measurements Instruments checklist. The minimal clinically important difference (MCID) was evaluated using distribution and anchor methods. Spearman correlations were used to compare CARATKids scores with external measures of control. Receiver operating characteristic curve analysis was performed to establish cutoff values. Fifty children completed both visits. The Cronbach α and intraclass correlation coefficient of CARATKids were 0.81 and 0.85, respectively. The Guyatt responsiveness index was -1.34, and within-patient change in clinically unstable patients (n = 31) was significant (P = .02). As for cross-sectional and longitudinal validity, correlation coefficients ranged from 0.58 to 0.77 (P asthma and allergic rhinitis control in Brazilian children. A score of 6 or higher on CARATKids identifies uncontrolled disease, and a score of 3 or lower excludes poor disease control. Copyright © 2017 American College of Allergy, Asthma & Immunology.

    The challenges faced in developing value-based diagnostics has resulted in few of these tests reaching the clinic, leaving many treatment modalities without matching diagnostics to select patients for particular therapies. Many patients receive therapies from which they are unlikely to benefit, resulting in worse outcomes and wasted health care resources. The paucity of value-based diagnostics is a result of the scientific challenges in developing predictive markers, specifically: (1) complex biology, (2) a limited research infrastructure supporting diagnostic development, and (3) the lack of incentives for diagnostic developers to invest the necessary resources. Better access to biospecimens can address some of these challenges. Methodologies developed to evaluate biomarkers from biospecimens archived from patients enrolled in randomized clinical trials offer the greatest opportunity to develop and validate high-value molecular diagnostics. An alternative opportunity is to access high-quality biospecimens collected from large public and private longitudinal observational cohorts such as the UK Biobank, the US Million Veteran Program, the UK 100,000 Genomes Project, or the French E3N cohort. Value-based diagnostics can be developed to work in a range of samples including blood, serum, plasma, urine, and tumour tissue, and better access to these high-quality biospecimens with clinical data can facilitate biomarker research.

    Full Text Available The aim of this study was to determine and validate prediction equations for digestible (DE and metabolizable energy (ME of corn for growing pigs. The prediction equations were developed based on data on the chemical composition, digestible and metabolizable energy of corn grain (30 samples evaluated in experiments in Embrapa Suínos e Aves, Brazil. The equations were evaluated using regression analysis, and adjusted R² was the criterion for selection of the best models. Two equations were tested for DE and ME, each. To validate the equations, 1 experiment with 2 assays was performed to determine the values of DE and ME of 5 corn cultivars. In each assay, we used 24 growing pigs with initial average weight of 54.21 ± 1.68 kg in complete randomized block design with 6 treatments and 4 replicates. Treatments consisted of a reference diet and 5 ration tests composed of 60% of the reference diet and 40% of corn (1 of the 5 cultivars. Based on the results of the metabolic experiment and predicted values obtained in the equations, the validation of the equations was conducted using the lowest prediction error (pe as a criterion for selection. The equations that produced the most accurate estimates of DE and ME of corn were as follows: DE = 11812 – 1015.9CP – 837.9EE – 1641ADF + 2616.3Ash + 47.5(CP2 + 114.7(CF2 + 46(ADF2 – 1.6(NDF2 – 997.1(Ash2 + 151.9EECF + 23.2EENDF – 126.4CPCF + 136.4CPADF – 4.0CPNDF, with R2 = 0.81 and pe = 2.33; ME = 12574 – 1254.9CP – 1140.5EE – 1359.9ADF + 2816.3Ash + 77.6(CP2 + 92.3(CF2 + 54.1(ADF2 – 1.8(NDF2 – 1097.2(Ash2 + 240.6EECF + 26.3EENDF – 157.4CPCF + 96.5CPADF – 4.4CPNDF, with R2 = 0.89 and pe = 2.24. Thus, using the data on chemical composition, it is possible to derive prediction equations for DE and ME of corn for pigs; these equations seem to be valid because of the small prediction errors suggestive of high accuracy of these models.

    Objective The majority of cardiovascular diagnoses in the Danish National Patient Registry (DNPR) remain to be validated despite extensive use in epidemiological research. We therefore examined the positive predictive value (PPV) of cardiovascular diagnoses in the DNPR. Design Population-based validation study. Setting 1 university hospital and 2 regional hospitals in the Central Denmark Region, 2010–2012. Participants For each cardiovascular diagnosis, up to 100 patients from participating hospitals were randomly sampled during the study period using the DNPR. Main outcome measure Using medical record review as the reference standard, we examined the PPV for cardiovascular diagnoses in the DNPR, coded according to the International Classification of Diseases, 10th Revision. Results A total of 2153 medical records (97% of the total sample) were available for review. The PPVs ranged from 64% to 100%, with a mean PPV of 88%. The PPVs were ≥90% for first-time myocardial infarction, stent thrombosis, stable angina pectoris, hypertrophic cardiomyopathy, arrhythmogenic right ventricular cardiomyopathy, takotsubo cardiomyopathy, arterial hypertension, atrial fibrillation or flutter, cardiac arrest, mitral valve regurgitation or stenosis, aortic valve regurgitation or stenosis, pericarditis, hypercholesterolaemia, aortic dissection, aortic aneurysm/dilation and arterial claudication. The PPVs were between 80% and 90% for recurrent myocardial infarction, first-time unstable angina pectoris, pulmonary hypertension, bradycardia, ventricular tachycardia/fibrillation, endocarditis, cardiac tumours, first-time venous thromboembolism and between 70% and 80% for first-time and recurrent admission due to heart failure, first-time dilated cardiomyopathy, restrictive cardiomyopathy and recurrent venous thromboembolism. The PPV for first-time myocarditis was 64%. The PPVs were consistent within age, sex, calendar year and hospital categories. Conclusions The validity of

    The authors assessed the psychometric properties of the Valued Activity Inventory for Adults With Cancer (VAI-AC), a self-report instrument that measures activity limitations. Participants included 50 older adults undergoing chemotherapy who completed the VAI-AC and measures of physical and mental function, symptom intensity, and mood 3 days before and the day of chemotherapy. Test-retest reliability was assessed by determining the average number of items for which the importance of an activity was rated consistently and by calculating the intraclass correlation coefficient (ICC) for the first and second VAI-AC scores. Convergent validity was assessed by correlating the VAI-AC scores with the other measures. Participants consistently rated the importance of 90% of the items. The 72-hour test-retest reliability ICC was 0.67. Participants with fewer activity limitations indicated better physical function (r = 0.58, p < .001), better mental function (r = 0.55, p < .001), lower symptom intensity (r = -0.57, p < .001), and fewer depressive symptoms (r = -0.68, p < .001). The VAI-AC demonstrated evidence of test-retest reliability and convergent validity in this convenience sample of older adults undergoing chemotherapy for cancer.

    The main goal of flight clearance is to use the structured singular value (μ) analysis of the flight control system when some parameters in the system vary in a certain range. As theμ-analysis can only be done on a linear fractional transformation (LFT) model, the first step of flight clearance is to generate the LFT model of the flight control system. In this paper, based on the introduction of basic theory of LFT and μ-analysis, an X-fighter is chosen as an example to utilize the proposed methods. In order to realize the flight clearance process automatically, a novel software package based on MATLAB programming language is developed. The results of simulation experiments validate the feasibility and effectiveness of the novel methods proposed in this paper.

A total of 730 adolescents participated in the study, 482 Brazilian (213 boys and 269 girls with average age of 15 years (SD= 1.1 and 238 Portuguese (117 boys and 121 girls with average age of 15.4 years (SD= 1.8. In both samples, the PVQ-24 showed satisfactory internal consistency, and the proposed factor structure was confirmed (four systems: materialistic, religious, hedonistic, and post-materialist. The post-materialist system was organized into three subsystems: social well-being, individual well-being and occupational well-being. In both samples, confirmatory factor analysis and multidimensional scaling supported the hypotheses regarding content (four systems and three subsystems, structure (two dimensions and compatibility (positive correlations between systems.

  8. Project deliverables - a waste of time or a chance for knowledge transfer and dissemination?

    Science.gov (United States)

    2016-04-01

    Deliverables are a common tool to measure a distinct output of a project. They should be meaningful in terms of the project's objectives and are normally constituted by e.g. a written report or document, a developed tool or software, an organized training or conference. They can be scientific or technical. The number of deliverables must be reasonable and commensurate to the project and its content. Deliverables as contractual obligations are often time consuming and often seen as a waste of "research" time, as one more administrative task without any use. However, deliverables are needed to verify the progress of a project and to convince the sponsor that the project is going in the right direction and the money well-invested. The presentation will deal with the question on how to use a deliverable in a profitable way for the project and what are the possibilities of use.

    A practical intervention program, targeting the safety belt use of pizza deliverers at two stores, increased significantly the use of both safety belts (143% above baseline) and turn signals (25% above baseline). Control subjects (i.e., pizza deliverers at a third no-intervention store and patrons driving to the pizza stores) showed no changes in belt or turn signal use over the course of 7-month study. The intervention program was staggered across two pizza stores and consisted of a group meeting wherein employees discussed the value of safety belts, received feedback regarding their low safety belt use, offered suggestions for increasing their belt use, and made a personal commitment to buckle up by signing buckle-up promise cards. Subsequently, employee-designed buckle-up reminder signs were placed in the pizza stores. By linking license plate numbers to individual driving records, we examined certain aspects of driving history as moderators of pre- and postintervention belt use. Although baseline belt use was significantly lower for drivers with one or more driving demerits or accidents in the previous 5 years, after the intervention these risk groups increased their belt use significantly and at the same rate as drivers with no demerits or accidents. Whereas baseline belt use was similar for younger (under 25) and older (25 or older) drivers, younger drivers were markedly more influenced by the intervention than were older drivers. Individual variation in belt use during baseline, intervention, and follow-up phases indicated that some drivers require more effective and costly intervention programs to motivate their safe driving practices.

    This deliverable provides a preliminary specification of the layout and target operation parameters for the FCC-hh hadron collider concept. They serve as starting point for the studies in all work packages. The goal of the FCC hadron collider is to provide proton-proton collisions at a centre-of-mass energy of 100 TeV. The machine is compatible with ion beam operation. Assuming a nominal dipole field of 16 T, such a machine is based on a perimeter of 100 km. The machine is designed to accommodate two main proton experiments that are operated simultaneously. The machine delivers a peak luminosity of 5-30 x 1034 cm-2s-1. The layout allows for two additional special-purpose experiments.

    1998-05-01

    Deliverability on the Interstate Natural Gas Pipeline System examines the capability of the national pipeline grid to transport natural gas to various US markets. The report quantifies the capacity levels and utilization rates of major interstate pipeline companies in 1996 and the changes since 1990, as well as changes in markets and end-use consumption patterns. It also discusses the effects of proposed capacity expansions on capacity levels. The report consists of five chapters, several appendices, and a glossary. Chapter 1 discusses some of the operational and regulatory features of the US interstate pipeline system and how they affect overall system design, system utilization, and capacity expansions. Chapter 2 looks at how the exploration, development, and production of natural gas within North America is linked to the national pipeline grid. Chapter 3 examines the capability of the interstate natural gas pipeline network to link production areas to market areas, on the basis of capacity and usage levels along 10 corridors. The chapter also examines capacity expansions that have occurred since 1990 along each corridor and the potential impact of proposed new capacity. Chapter 4 discusses the last step in the transportation chain, that is, deliverability to the ultimate end user. Flow patterns into and out of each market region are discussed, as well as the movement of natural gas between States in each region. Chapter 5 examines how shippers reserve interstate pipeline capacity in the current transportation marketplace and how pipeline companies are handling the secondary market for short-term unused capacity. Four appendices provide supporting data and additional detail on the methodology used to estimate capacity. 32 figs., 15 tabs.

    Isotope angiography performed by intravenous injection of technetium 99m pertechnetate has been demonstrated to be of value in the diagnosis and management of a variety of disorders of the large arteries. An improved technique of isotope angiography is described and the technique validated (53 cases) in normal and diseased arteries by correlating it with conventional contrast arteriography and/or operative findings. Peripheral arteries as far distal as the wrist or mid-calf have been accurately visualized and quantitation of isotope arrival times and total isotope activity in different parts of the arterial tree has provided a means of evaluating the hemodynamic significance of stenosing lesions. Thirty-nine arterial reconstructions were studied by this technique. Seven of 27 (26%) clinically patent arterial reconstructions were found to be harboring significant and potentially dangerous imperfections which were clinically unsuspected. Nine of 12 (75%) arterial reconstructions thought clinically to be occluded were demonstrated to be patent, obviating the need for invasive contrast arteriography. Isotope angiography may be used with no risk for the immediate postoperative and long-term evaluation of arterial reconstructions. Only those patients with abnormalities identified on isotope angiography need have conventional contrast arteriography for further delineation of the abnormality so that it may be repaired before it causes failure of the reconstruction.

  16. A fundamental special-relativistic theory valid for all real-valued speeds

    1984-01-01

    Full Text Available This paper constitutes a fundamental rederivation of special relativity based on the c-invariance postulate but independent of the assumption ds′2=±ds2 (Einstein [1], Kittel et al [2], Recami [3], the equivalence principle, homogeneity of space-time, isotropy of space, group properties and linearity of space-time transformations or the coincidence of the origins of inertial space-time frames. The mathematical formalism is simpler than Einstein's [4] and Recami's [3]. Whilst Einstein's subluminal and Recami's superluminal theories are rederived in this paper by further assuming the equivalence principle and “mathematical inverses” [4,3], this paper derives (independent of these assumptions with physico-mathematical motivation an alternate singularity-free special-relativistic theory which replaces Einstein's factor [1/(1−V2/c2]12 and Recami's extended-relativistic factor [1/(V2/c2−1]12 by [(1−(V2/c2n/(1−V2/c2]12, where n equals the value of (m(V/m02 as |V|→c. In this theory both Newton's and Einstein's subluminal theories are experimentally valid on account of negligible terms. This theory implies that non-zero rest mass luxons will not be detected as ordinary non-zero rest mass bradyons because of spatial collapse, and non-zero rest mass tachyons are undetectable because they exist in another cosmos, resulting in a supercosmos of matter, with the possibility of infinitely many such supercosmoses, all moving forward in time. Furthermore this theory is not based on any assumption giving rise to the twin paradox controversy. The paper concludes with a discussion of the implications of this theory for general relativity.

    Full Text Available The project MUSICA (MUlti-platform remote Sensing of Isotopologues for investigating the Cycle of Atmospheric water integrates tropospheric water vapour isototopologue remote sensing and in-situ observations. This paper presents a first empirical validation of MUSICA's H2O and δD remote sensing products (generated from ground-based FTIR, Fourier Transform InfraRed, spectrometer and space-based IASI, Infrared Atmospheric Sounding Interferometer, observation. As reference we use well calibrated in-situ measurements made aboard an aircraft (between 200 and 6800 m a.s.l. by the dedicated ISOWAT instrument and on the island of Tenerife at two different altitudes (at Izaña, 2370 m a.s.l., and at Teide, 3550 m a.s.l. by two commercial Picarro L2120-i water isotopologue analysers. The comparison to the ISOWAT profile measurements shows that the remote sensors can well capture the variations in the water vapour isotopologues and the scatter with respect to the in-situ references suggests a δD random uncertainty for the FTIR product of much better than 45‰ in the lower troposphere and of about 15‰ for the middle troposphere. For the middle tropospheric IASI δD product the study suggests a respective uncertainty of about 15‰. In addition, we find indications for a positive δD bias in the remote sensing products. The δD data are scientifically interesting only if they add information to the H2O observations. We are able to qualitatively demonstrate the added value of the MUSICA δD remote sensing data by comparing δD-vs.-H2O curves. First, we show that the added value of δD as seen in the Picarro data is similarly seen in FTIR data measured in coincidence. Second, we document that the δD-vs.-H2O curves obtained from the different in-situ and remote sensing data sets (ISOWAT, Picarro at Izaña and Teide, FTIR, and IASI consistently identify two different moisture transport pathways to the subtropical north eastern Atlantic free troposphere.

    2009-04-01

    Many geomorphological studies focus on fundamental research questions in large parts, although there are lots of applied fields like landslide hazard assessment or water framework directive. As fundamental research is a common property, their outcomes should be more "open" and accessible to the public. This means that scientists have to find new ways presenting their results and outcomes besides publishing in scientific journals. This paper shows possibilities for a valorisation of geomorphologic research deliverables using print as well as digital media. Geotrails explain remarkable and exciting landscape features using information boards and become more and more popular and important for tourism in many parts of the world. With the growing interest in environmental change and outdoor activities, print media like field guides reach an increasing number of people. Field guides and Geotrails can be coupled in order to arise awareness about geomorphological landforms and to deliver more specific information on the site beyond the information given on the boards in the field. As field guides are designed for the general public they can be used for educational purposes as well. Today, this information can also be found in the internet offering virtual trips through landscapes using dynamic maps. Here, server side GIS technologies (WebGIS) using standardised interfaces provide new possibilities to show geomorphic data to the public and to share them with the scientific community. Furthermore, data formats like XML or KML are powerful tools for data exchange and can be used in interactive data viewers like Google Earth. We will present the Geotrail "Geomorphologischer Lehrpfad am Fuße der Zugspitze. Das Reintal - Eine Wanderung durch Raum und Zeit" (Bavarian Alps, Germany). Additionally, three geomorphologic WebGIS applications (Geomorphologic map Turtmanntal, Permafrostmap of Austria, Geomorphologic maps of Germany) will exemplify how geomorphologic information and

    Full Text Available Despite its popularity, the concept of service quality in the marketingliterature is still ambiguously and vaguely defined. Several measurementscales have been proposed, but some of these take into accountonly the method of measurement and ignore the idea that the sameinstrument may not be able to be automatically applied in different industriesor in different cultures. Therefore the purpose of this paperis twofold: first to validate the perceived retail banking service scale inthe case of a small transitional economy of Europe, and second to researchservice quality-customer satisfaction relationship and the role ofperceived value within it. Content validity, face validity, construct validity,convergent validity, discriminant validity as well as nomologicalvalidity were assessed with EFA, CFA and SEM. The present research isthe first attempt to measure the relationships among the concepts researchedin the retailing banking industry in transitional economies inEurope. Therefore, its major finding, that the perceived value variablehas a potential to be mediating variable between perceived quality andcustomer satisfaction relationship in retail banking settings, could be ofinterest also for other researchers in transitional economies in Europeand also for researchers from other environments.

    The Jobs and Economic Development Impacts (JEDI) models, developed by the National Renewable Energy Laboratory (NREL) for the U.S. Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy (EERE), use input-output methodology to estimate gross (not net) jobs and economic impacts of building and operating selected types of renewable electricity generation and fuel plants. This analysis provides the DOE with an assessment of the value, impact, and validity of the JEDI suite of models. While the models produce estimates of jobs, earnings, and economic output, this analysis focuses only on jobs estimates. This validation report includes an introduction to JEDI models, an analysis of the value and impact of the JEDI models, and an analysis of the validity of job estimates generated by JEDI model through comparison to other modeled estimates and comparison to empirical, observed jobs data as reported or estimated for a commercial project, a state, or a region.

The comparison to the ISOWAT profile measurements shows that the remote sensors can well capture the variations in the water vapour isotopologues, and the scatter with respect to the in situ references suggests a δD random uncertainty for the FTIR product of much better than 45‰ in the lower troposphere and of about 15‰ for the middle troposphere. For the middle tropospheric IASI δD product the study suggests a respective uncertainty of about 15‰. In both remote sensing data sets we find a positive δD bias of 30-70‰. Complementing H2O observations with δD data allows moisture transport studies that are not possible with H2O observations alone. We are able to qualitatively demonstrate the added value of the MUSICA δD remote sensing data. We document that the δD-H2O curves obtained from the different in situ and remote sensing data sets (ISOWAT, Picarro at Izaña and Teide, FTIR, and IASI) consistently identify two different moisture transport pathways to the subtropical north eastern Atlantic free troposphere.

    Full Text Available Electropolymerization processes of pyrrole and the usage of polypyrrole membrane as lysine and alanine deliverance have been studied by cyclic voltammetry technique. Polypyrrole membrane was prepared by electropolymerization processes of pyrrole in water based solvent containing sodium perchlorate as supporting electrolyte. Electropolymerization processes were carried out within potential range of 0-1100 mV vs Ag/AgCl reference electrode and at the scanning rate of 100 mV/s. In this study, lysine and alanine have been used as molecules which could easily be loaded on and released from polypyrrole membrane. The presence of lysine or alanine during electropolymerization process reduced the rate of electropolymerization of polypyrrole. In lysine or alanine transfer processes into polypyrrole membrane, the interaction between polypyrrole and lysine or alanine showed by the curve of E½ oxidation in respect of - log C. It proved that the E½ oxidation shifted to more positive potential showed by the increasing of concentration of lysine or alanine. Beside that, voltammetric responses of lysine and alanine transfered into polypyrrole membrane were found to be Nernstian. The results indicated that polypyrrole could be used as a sensor of lysine and alanine.   Keywords: Electropolymerization, polypyrrole membrane, voltammetry technique

  11. Multiple Imputation based Clustering Validation (MIV) for Big Longitudinal Trial Data with Missing Values in eHealth.

    Zhang, Zhaoyang; Fang, Hua; Wang, Honggang

    2016-06-01

    Web-delivered trials are an important component in eHealth services. These trials, mostly behavior-based, generate big heterogeneous data that are longitudinal, high dimensional with missing values. Unsupervised learning methods have been widely applied in this area, however, validating the optimal number of clusters has been challenging. Built upon our multiple imputation (MI) based fuzzy clustering, MIfuzzy, we proposed a new multiple imputation based validation (MIV) framework and corresponding MIV algorithms for clustering big longitudinal eHealth data with missing values, more generally for fuzzy-logic based clustering methods. Specifically, we detect the optimal number of clusters by auto-searching and -synthesizing a suite of MI-based validation methods and indices, including conventional (bootstrap or cross-validation based) and emerging (modularity-based) validation indices for general clustering methods as well as the specific one (Xie and Beni) for fuzzy clustering. The MIV performance was demonstrated on a big longitudinal dataset from a real web-delivered trial and using simulation. The results indicate MI-based Xie and Beni index for fuzzy-clustering are more appropriate for detecting the optimal number of clusters for such complex data. The MIV concept and algorithms could be easily adapted to different types of clustering that could process big incomplete longitudinal trial data in eHealth services.

  12. Development and Preliminary Validation of a New Measure of Values in Scientific Work.

    Science.gov (United States)

    English, Tammy; Antes, Alison L; Baldwin, Kari A; DuBois, James M

    2017-06-08

    In this paper we describe the development and initial psychometric evaluation of a new measure, the values in scientific work (VSW). This scale assesses the level of importance that investigators attach to different VSW. It taps a broad range of intrinsic, extrinsic, and social values that motivate the work of scientists, including values specific to scientific work (e.g., truth and integrity) and more classic work values (e.g., security and prestige) in the context of science. Notably, the values represented in this scale are relevant to scientists regardless of their career stage and research focus. We administered the VSW and a measure of global values to 203 NIH-funded investigators. Exploratory factor analyses suggest the delineation of eight VSW, including autonomy, research ethics, social impact, income, collaboration, innovation and growth, conserving relationships, and job security. These VSW showed predictable and distinct associations with global values. Implications of these findings for work on research integrity and scientific misconduct are discussed.

  13. Validating a method for transferring social values of ecosystem services between public lands in the Rocky Mountain region

    Sherrouse, Benson C.; Semmens, Darius J.

    2014-01-01

    With growing pressures on ecosystem services, social values attributed to them are increasingly important to land management decisions. Social values, defined here as perceived values the public ascribes to ecosystem services, particularly cultural services, are generally not accounted for through economic markets or considered alongside economic and ecological values in ecosystem service assessments. Social-values data can be elicited through public value and preference surveys; however, limitations prevent them from being regularly collected. These limitations led to our three study objectives: (1) demonstrate an approach for applying benefit transfer, a nonmarket-valuation method, to spatially explicit social values; (2) validate the approach; and (3) identify potential improvements. We applied Social Values for Ecosystem Services (SolVES) to survey data for three national forests in Colorado and Wyoming. Social-value maps and models were generated, describing relationships between the maps and various combinations of environmental variables. Models from each forest were used to estimate social-value maps for the other forests via benefit transfer. Model performance was evaluated relative to the locally derived models. Performance varied with the number and type of environmental variables used, as well as differences in the forests' physical and social contexts. Enhanced metadata and better social-context matching could improve model transferability.

    2016-01-01

    We investigate the utility of the convex hull to analyze physical questions related to the dispersion of a group of much more than four Lagrangian tracer particles in a turbulent flow. Validation of standard dispersion behaviors is a necessary preliminary step for use of the convex hull to describe turbulent flows. In simulations of statistically homogeneous and stationary Navier-Stokes turbulence, neutral fluid Boussinesq convection, and MHD Boussinesq convection we show that the convex hull can be used to reasonably capture the dispersive behavior of a large group of tracer particles. We validate dispersion results produced with convex hull analysis against scalings for Lagrangian particle pair dispersion. In addition to this basic validation study, we show that convex hull analysis provides information that particle pair dispersion does not, in the form of a extreme value statistics, surface area, and volume for a cluster of particles. We use the convex hull surface area and volume to examine the degree of...

    2016-07-01

    Full Text Available In many structures and components cracks, which are exposed to a 3D-mixed-mode-loading, occur due to multiaxial loading situation. A reliable evaluation of those components requires fracture mechanical criteria validated by experimental investigations. Within this article 3D-mixed-mode criteria for static as well as cyclic loadings will be presented. Experiments for pure mode I-loading, pure mode II-loading, pure mode IIIloading and 2D- as well as 3D-mixed-mode-loading combinations are performed using specially developed specimens and loading devices. By comparing the experimental results with criteria a widely validity of criteria and a generally conservative behaviour are revealed.

    To measure the $R$ value in an energy scan experiment with $\\ee$ collisions, precise calculation of initial state radiation is required in event generators. We present an event generator for this consideration, which incorporates initial state radiation effects up to the second order accuracy, and the radiative correction factor is calculated using the totally hadronic Born cross section. The measured exclusive processes are generated according to their cross sections, while the unknown processes are generated using the LUND Area Law model, and its parameters are tuned with data collected at $\\sqrt s=3.65$ GeV. The optimized values are validated with data in the range $\\sqrt s=2.2324\\sim3.671$ GeV. These optimized parameters are universally valid for event generation below the $D\\bar D$ threshold.

  19. Different Diagnosis, Shared Vulnerabilities: The Value of Cross Disorder Validation of Capacity to Consent.

    Science.gov (United States)

    Rosen, Allyson; Weitlauf, Julie C

    2015-01-01

    A screening measure of capacity to consent can provide an efficient method of determining the appropriateness of including individuals from vulnerable patient populations in research, particularly in circumstances in which no caregiver is available to provide surrogate consent. Seaman et al. (2015) cross-validate a measure of capacity to consent to research developed by Jeste et al. (2007). They provide data on controls, caregivers, and patients with mild cognitive impairment and dementia. The study demonstrates the importance of validating measures across disorders with different domains of incapacity, as well as the need for timely and appropriate follow-up with potential participants who yield positive screens. Ultimately clinical measures need to adapt to the dimensional diagnostic approaches put forward in DSM 5. Integrative models of constructs, such as capacity to consent, will make this process more efficient by avoiding the need to test measures in each disorder. Until then, cross-validation studies, such as the work by Seaman et al. (2015) are critical.

  20. Adaptive interpretation of gas well deliverability tests with generating data of the IPR curve

    2017-01-01

    The paper considers topical issues of improving accuracy of estimated parameters given by data obtained from gas well deliverability tests, decreasing test time, and reducing gas emissions into the atmosphere. The aim of the research is to develop the method of adaptive interpretation of gas well deliverability tests with a resulting IPR curve and using a technique of generating data, which allows taking into account additional a priori information, improving accuracy of determining formation pressure and flow coefficients, reducing test time. The present research is based on the previous theoretical and practical findings in the spheres of gas well deliverability tests, systems analysis, system identification, function optimization and linear algebra. To test the method, the authors used the field data of deliverability tests of two wells, run in the Urengoy gas and condensate field, Tyumen Oblast. The authors suggest the method of adaptive interpretation of gas well deliverability tests with the resulting IPR curve and the possibility of generating data of bottomhole pressure and a flow rate at different test stages. The suggested method allows defining the estimates of the formation pressure and flow coefficients, optimal in terms of preassigned measures of quality, and setting the adequate number of test stages in the course of well testing. The case study of IPR curve data processing has indicated that adaptive interpretation provides more accurate estimates on the formation pressure and flow coefficients, as well as reduces the number of test stages.

  5. Landscape-scale learning: from lectures to professional deliverables

    Science.gov (United States)

    Follain, S.; Devaux, N.; Colin, F.

    2009-04-01

    Earth Science ingenieers (Master degree) need to be trained in multidisciplinary approaches but also to learn how to combine theoretical and practical knowledge. Nevertheless we notice it is not always easy to combine in a same lecture, theoretical and practical issues. In order to build bridges between these instructions we propose to student a new teaching unit: "Sustainability Diagnosis". Its originalities are i) to be couple to an other (theoretical) teaching unit dealing with landscape-scale learning ii) to be performed under a project mode and iii) to provide deliverables ordered by professional users, e.g. farmers, catchment managers. The landscape-scale learning is a classical learning period with lectures provided by specialists in various disciplines e.g. Soil Science, Hydrology, Agronomy, which focus on a common spatial scale, the landscape. It explicitly develops knowledge on energy and matter transfers between landscape components and explains potential effects of human-induced disturbances on both landscape and fluxes evolution. The deliverables for the farmer (chosen professional user) concern issues on his crop system sustainability. It requires a diagnosis in one hand on soil use and management potentialities and in another hand on environmental externalities (soil and water conservation) induced by the cropping system. The communication will present the work done by 14 students during this new teaching unit (Sustainability Diagnosis) of two weeks. This first attempt expertized a one square kilometer area located in Saint-Chinian vineyard region (South of France). This production area with guarantee of origin (AOC) has productivity constraints linked to landscape properties which directly impact farmer decisions. In the same time it has been shown that vineyard crop system induces water pollution by pesticides and increases soil degradation; in a sustainability perspective, these environmental impacts need to be reduced. The learning period was

    Recent developments in service marketing have demonstrated the potential value co-creation by customers who participate in online brand communities (OBCs). Therefore, this study forecasts the co-created value by understanding the participation/behavior of customers in a multi-stakeholder OBC. This six-phase qualitative and quantitative investigation conceptualizes, constructs, refines, and tests a 12-item three-dimensional scale for measuring key factors that are related to the experience, interpersonal interactions, and social relationships that affect the value co-creation by customers in an OBC. The scale captures stable psychometric properties, measured using various reliability and validity tests, and can be applied across various industries. Finally, the utility implications and limitations of the proposed scale are discussed, and potential future research directions considered.

  7. Heart rate variability indicates emotional value during pro-social economic laboratory decisions with large external validity.

    Fooken, Jonas

    2017-03-10

    The present study investigates the external validity of emotional value measured in economic laboratory experiments by using a physiological indicator of stress, heart rate variability (HRV). While there is ample evidence supporting the external validity of economic experiments, there is little evidence comparing the magnitude of internal levels of emotional stress during decision making with external stress. The current study addresses this gap by comparing the magnitudes of decision stress experienced in the laboratory with the stress from outside the laboratory. To quantify a large change in HRV, measures observed in the laboratory during decision-making are compared to the difference between HRV during a university exam and other mental activity for the same individuals in and outside of the laboratory. The results outside the laboratory inform about the relevance of laboratory findings in terms of their relative magnitude. Results show that psychologically induced HRV changes observed in the laboratory, particularly in connection with social preferences, correspond to large effects outside. This underscores the external validity of laboratory findings and shows the magnitude of emotional value connected to pro-social economic decisions in the laboratory.

    1999-12-01

    Full Text Available Teacher orientation to the inculcation of values across school curriculum-a function of the teacher knowledge and attitudes-has been conceptualised as his or her (1 identification with the goals of the curriculum, and (2 conformity with the predetermined instructional behaviours. Based on this framework, the study explored the construct of teacher orientation to the inculcation of values across school subjects. More specifically, the study examined the likelihood of two underlying dimensions explaining the presence of variability in teacher orientation and the reliability of the dimensions. Using a 15-item instrument developed earlier for a descriptive inquiry, the present study measured and analysed responses from 103 secondary school teachers from two randomly selected schools. To arrive at the conclusions, the study applied principal component analysis and Cronbach's alpha procedures. The results suggested that teacher orientation to value inculcation is a multidimensional construct. The more reliable dimensions of Teacher Orientation were found to be goal identification, conformity to planning tasks, and conformity to delivery tasks. The results add new information to, and may serve as a guide for future research.

    2009-01-01

    The flowing mechanism of a low permeability gas reservoir is different from a conventional gas reservoir, espe-cially for that with higher irreducible water saturation the threshold pressure gradient exists. At present, in all the deliverability equation, the additional pressure drop caused by the threshold pressure gradient is viewed as constant, but this method has big error in the practical application. Based on the non-Darcy steady flow equation, the limited integral of the additional pressure drop is solved in this paper and it is realized that the additional pressure drop is not a constant but has something to do with production data, and a new deliverability equation is derived, with the relevant processing method for modified isochronal test data. The new deliverability equation turns out to be practical through onsite applica-tion.

    Metal-organic frameworks (MOFs) are a rapidly emerging class of nanoporous materials with largely tunable chemistry and diverse applications in gas storage, gas purification, catalysis, etc. Intensive efforts are being made to develop new MOFs with desirable properties both experimentally and computationally in the past decades. To guide experimental synthesis with limited throughput, we develop a computational methodology to explore MOFs with high methane deliverable capacity. This de novo design procedure applies known chemical reactions, considers synthesizability and geometric requirements of organic linkers, and evolves a population of MOFs with desirable property efficiently. We identify about 500 MOFs with higher deliverable capacity than MOF-5 in 10 networks. We also investigate the relationship between deliverable capacity and internal surface area of MOFs. This methodology can be extended to MOFs with multiple types of linkers and multiple SBUs. DE-FG02- 12ER16362.

    Metal organic frameworks (MOFs) are actively being explored as potential adsorbed natural gas storage materials for small vehicles. Experimental exploration of potential materials is limited by the throughput of synthetic chemistry. We here describe a computational methodology to complement and guide these experimental efforts. The method uses known chemical transformations in silico to identify MOFs with high methane deliverable capacity. The procedure explicitly considers synthesizability with geometric requirements on organic linkers. We efficiently search the composition and conformation space of organic linkers for nine MOF networks, finding 48 materials with higher predicted deliverable capacity (at 65 bar storage, 5.8 bar depletion, and 298 K) than MOF-5 in four of the nine networks. The best material has a predicted deliverable capacity 8% higher than that of MOF-5. US Department of Energy.

Beef tallow was added to the summer milkfat in the ratios 5%, 10%, 15% and 50% w/w. Thin layer chromatography was applied to obtain the triglycerides fraction of each sample obtained. Gas chromatography was used to identify the fatty acid content of the winter, summer and the admixtures. Reichert-Meissl (RM, Polenske (P and Iodine values were also determined for each sample. It was concluded that the (RM of the winter and the summer milkfat were 25.52±0.511 and 28.74±0.568, respectively. The (P and iodine values were 1.94±0.162, 2.53±0.146 and 42.1±0.85, 30.33±0.839 in the same respect. The addition of beef tallow to the milkfat in the ratios 5% and 10% did not affect the (RM and (P values of the resultant admixtures. The presence of 15% beef tallow in milkfat slightly affected the (RM, (P and iodine values. The addition of 50% beef tallow to the milkfat got the values of (RM and (P out of the normal range. The iodine values was still within the normal range of milkfat. It was also observed that the addition of beef tallow in the ratios 5%, 10% and 15% to summer milkfat, improved the fatty acid pattern of the milk fat, while the 50% beef tallow in milkfat, decreased all the short chain fatty acids. The determination of the (RM, (P and iodine values to detect the beef tallow as an adulterant in pure milkfat is not sufficient at 5% and 10% beef tallow in milkfat.

    Extreme events are of widespread concern due to their damaging consequences on natural and anthropogenic systems. From science to applications the statistical attributes of rare and infrequent occurrence and low probability become connected with the socio-economic aspect of strong impact. Specific end-user needs regarding information about extreme events depend on the type of application, but as a joining element there is always the request for easily accessible climate change information with a clear description of their uncertainties and limitations. Within the Perfect-Predictor Experiment of the COST Action VALUE extreme indices modelled from a wide range of downscaling methods are compared to reference indices calculated from observational data.

    , the authors have tried to determine if the ICP monitors from major manufacturers were affected by electrostatic discharges (ESDs), if the changes were permanent or transient in nature, and if the changes were modified by the addition of different electrical appliances normally used in the neurointensive care...... unit environment. Methods The authors established a test setup in the neurointensive care unit using a large container filled with isotonic saline, creating a phantom patient. Intracranial pressure monitors were sequentially lowered into the container and subjected to a predefined test battery of ESDs....... Results Five pressure monitors from 4 manufacturers were evaluated. Three monitors containing electrical circuitry at the tip of the transducer were all affected by ESDs. Clinically significant permanent changes in the reported ICP values for 1 pressure monitor were observed, as well as temporary...

  17. Gene expression classification of colon cancer into molecular subtypes: characterization, validation, and prognostic value.

    Laetitia Marisa

    Full Text Available BACKGROUND: Colon cancer (CC pathological staging fails to accurately predict recurrence, and to date, no gene expression signature has proven reliable for prognosis stratification in clinical practice, perhaps because CC is a heterogeneous disease. The aim of this study was to establish a comprehensive molecular classification of CC based on mRNA expression profile analyses. METHODS AND FINDINGS: Fresh-frozen primary tumor samples from a large multicenter cohort of 750 patients with stage I to IV CC who underwent surgery between 1987 and 2007 in seven centers were characterized for common DNA alterations, including BRAF, KRAS, and TP53 mutations, CpG island methylator phenotype, mismatch repair status, and chromosomal instability status, and were screened with whole genome and transcriptome arrays. 566 samples fulfilled RNA quality requirements. Unsupervised consensus hierarchical clustering applied to gene expression data from a discovery subset of 443 CC samples identified six molecular subtypes. These subtypes were associated with distinct clinicopathological characteristics, molecular alterations, specific enrichments of supervised gene expression signatures (stem cell phenotype-like, normal-like, serrated CC phenotype-like, and deregulated signaling pathways. Based on their main biological characteristics, we distinguished a deficient mismatch repair subtype, a KRAS mutant subtype, a cancer stem cell subtype, and three chromosomal instability subtypes, including one associated with down-regulated immune pathways, one with up-regulation of the Wnt pathway, and one displaying a normal-like gene expression profile. The classification was validated in the remaining 123 samples plus an independent set of 1,058 CC samples, including eight public datasets. Furthermore, prognosis was analyzed in the subset of stage II-III CC samples. The subtypes C4 and C6, but not the subtypes C1, C2, C3, and C5, were independently associated with shorter relapse

    Electroconvulsive therapy is the most effective therapy for major depressive disorder (MDD). The remission rate is above 50% in previously pharmacoresistant patients but the mechanisms of action are not fully understood. Electroconvulsive stimulation (ECS) in rodents mimics antidepressant electroconvulsive therapy (ECT) in humans and is widely used to investigate the underlying mechanisms of ECT. For the translational value of findings in animal models it is essential to establish models with the highest construct, face and predictive validity possible. The commonly used model for ECT in rodents does not meet the demand for high construct validity. For ECT, cortical surface electrodes are used to induce therapeutic seizures whereas ECS in rodents is exclusively performed by auricular or corneal electrodes. However, the stimulation site has a major impact on the type and spread of the induced seizure activity and its antidepressant effect. We propose a method in which ECS is performed by screw electrodes placed above the motor cortex of rats to closely simulate the clinical situation and thereby increase the construct validity of the model. Cortical ECS in rats induced reliably seizures comparable to human ECT. Cortical ECS was more effective than auricular ECS to reduce immobility in the forced swim test. Importantly, auricular stimulation had a negative influence on the general health condition of the rats with signs of fear during the stimulation sessions. These results suggest that auricular ECS in rats is not a suitable ECT model. Cortical ECS in rats promises to be a valid method to mimic ECT. Copyright © 2014 Elsevier Ltd. All rights reserved.

  19. Can a threshold value be used to classify chondrichthyan reproductive modes: systematic review and validation using an oviparous species.

    Directory of Open Access Journals (Sweden)

    Holly A Frazer

    Full Text Available The maternal-embryonic nutritional relationship in chondrichthyans has been poorly explored. Consequently, accurately discerning between their different reproductive modes is difficult; especially lecithotrophy and incipient histotrophy. This present study is the first to assess changes in mass throughout embryonic development of an oviparous chondrichthyan other than Scyliorhinus canicula. Heterodontus portusjacksoni egg cases were collected and used to quantify the gain or loss of wet mass, dry mass, water content, inorganic and organic matter from freshly deposited eggs (without macroscopically visible embryos to near full-term embryos. A loss in organic mass of ~40% found from this study is approximately double the values previously obtained for S. canicula. This raises concerns for the validity of the current threshold value used to discern between lecithotrophic and matrotrophic species. Accordingly, 26 studies published in the primary literature between 1932 and 2012 addressing the maternal-embryonic nutritional relationship in sharks were reviewed. Values for changes in mass reported for over 20 different shark species were synthesised and recalculated, revealing multiple typographical, transcribing, calculation and rounding errors across many papers. These results suggest that the current threshold value of -20% established by previous studies is invalid and should be avoided to ascertain the reproductive mode of aplacental viviparous species.

    This paper shows the procedure performed to validate the migration equation and the migration parameters' values presented in a previous paper (Legarda et al., 2011) regarding the migration of (137)Cs in Spanish mainland soils. In this paper, this model validation has been carried out checking experimentally obtained activity concentration values against those predicted by the model. This experimental data come from the measured vertical activity profiles of 8 new sampling points which are located in northern Spain. Before testing predicted values of the model, the uncertainty of those values has been assessed with the appropriate uncertainty analysis. Once establishing the uncertainty of the model, both activity concentration values, experimental versus model predicted ones, have been compared. Model validation has been performed analyzing its accuracy, studying it as a whole and also at different depth intervals. As a result, this model has been validated as a tool to predict (137)Cs behaviour in a Mediterranean environment.

    According to Recommendation N°196 of the Australian Law Reform Commission (ALRC), the age at which a child reaches adulthood for the purposes of criminal law should be 18 years in all Australian jurisdictions. With specific reference to age at majority, the only tooth with development spanning adolescence (and thus the legally relevant 18 years of age) is the third molar, which limits the number of methods that can be applied from those available in the published literature. The aim of the present study is to test the accuracy of the third molar index (I3M=0.08), based on the correlation between chronological age and normalized measures of the open apices and height of the third mandibular molar, in order to assess the legal adult age of 18 years. Digital orthopantomographs of 143 living Australian subjects (72 boys and 71 girls) are analyzed. The results demonstrate that the sensitivity is 0.90 in boys and 0.90 in girls; associated specificity values are 0.85 and 0.87 respectively. We conclude that the cut-off value of I3M=0.08 is statistically robust and thus valid for forensic application in an Australian population.

    To determine normative values for the Timed Up and Go (TUG) test in typically developing children and adolescents and to validate its use in individuals with Down syndrome. Participants in this cross-sectional study were South Brazilian schoolchildren aged 3 to 18 years. In phase 1, 459 typically developing individuals (227 males, 232 females; mean age 10 y 8 mo (SD 4 y 4 mo) were included; and in phase 2, 40 individuals with Down syndrome (16 males, 24 females; mean age 10 y 6 mo (SD 4 y 4 mo). Anthropometric measurements, real leg length, TUG test scores, and Gross Motor Function Measure (GMFM) scores were evaluated. The association between the TUG test and possible predictive variables was analyzed. In phase 1, the mean time to perform the TUG test was 5.61 seconds (SD 1.06). Values were stratified in age groups that served as normative data for both sexes. A multiple linear regression analysis was conducted and the best variables to predict TUG scores were age and weight. The best model obtained presented an R(2) of 0.25 and a standard error of the estimate of 0.92. Excellent intrasession reliability in the three tests performed (intraclass correlation coefficient [ICC] of 0.93, 0.94, and 0.95) and between the sessions (both with an ICC of 0.95) was demonstrated. In phase 2, the test also showed excellent reproducibility (ICC=0.82 between the two tests performed). The performance time was significantly longer (ptest. This study provides normative values for the TUG test and shows that TUG scores can be predicted as a function of age and weight in typically developing individuals. The test can also be used for assessment of functional mobility in individuals with Down syndrome. © 2013 Mac Keith Press.

    Full Text Available Since the publication of the book“The occult debate” (Janse van Rensburg, 1999 it has become clear that epistemological views on occultism within the reformed tradition have drastically diverged. During the General Synod of the Dutch Reformed Church in 2007, the report of the Algemene Taakspan vir Leer en Aktuele Sake (ATLASon a ministry of deliverance denied the existence of the devil and claimed that it would be un-scientific to embark on an empirical research in this regard, because of the impossibility to verify information gathered in this manner. However, it is the hypothesis of this article that qualitative information could assist in attaining a clearer under-standing of the need for a ministry of deliverance. In this article the methodology of the qualitative research is explained and the narratives of participants are revealed. Thereafter the respon-ses of the participants are evaluated.

    2016-12-01

    While discrete choice experiments (DCEs) are increasingly used in the field of environmental valuation, they remain controversial because of their hypothetical nature and the contested reliability and validity of their results. We systematically reviewed evidence on the validity and reliability of environmental DCEs from the past thirteen years (Jan 2003-February 2016). 107 articles met our inclusion criteria. These studies provide limited and mixed evidence of the reliability and validity of DCE. Valuation results were susceptible to small changes in survey design in 45% of outcomes reporting reliability measures. DCE results were generally consistent with those of other stated preference techniques (convergent validity), but hypothetical bias was common. Evidence supporting theoretical validity (consistency with assumptions of rational choice theory) was limited. In content validity tests, 2-90% of respondents protested against a feature of the survey, and a considerable proportion found DCEs to be incomprehensible or inconsequential (17-40% and 10-62% respectively). DCE remains useful for non-market valuation, but its results should be used with caution. Given the sparse and inconclusive evidence base, we recommend that tests of reliability and validity are more routinely integrated into DCE studies and suggest how this might be achieved.

    AIMS/HYPOTHESIS: The list of validated type 2 diabetes susceptibility variants has recently been expanded from three to 19. The variants identified are common and have low penetrance in the general population. The aim of the study is to investigate the combined effect of the 19 variants by applyi...... analysis of the 19 validated variants enables detection of subgroups at substantially increased risk of type 2 diabetes; however, the discrimination between glucose-tolerant and type 2 diabetes individuals is still too inaccurate to achieve clinical value....

  11. Cost savings deliverables and criteria for the OST technology decision process

    Energy Technology Data Exchange (ETDEWEB)

    McCown, A.

    1997-04-01

    This document has been prepared to assist focus area (FA) technical and management teams in understanding the cost savings deliverables associated with a technology system during its research and development (R and D) phases. It discusses the usefulness of cost analysis in the decision-making process, and asserts that the level of confidence and data quality of a cost analysis is proportional to the maturity of the technology system`s development life cycle. Suggestions of specific investment criteria or cost savings metrics that a FA might levy on individual research projects are made but the final form of these elements should be stipulated by the FA management based on their rationale for a successful technology development project. Also, cost savings deliverables for a single FA will be more detailed than those for management of the Office of Science and Technology (OST). For example, OST management may want an analysis of the overall return on investment for each FA, while the FA program manager may want this analysis and the return on investment metrics for each technology research activity the FA supports.

    Ogan Komering Ilir (OKI) is located at the eastern of South Sumatra Province, 2030‧-4015‧ latitude and 104020‧-106000‧ longitude. Digital image of land was captured from Landsat 8 satellite path 124/row 062. Landsat 8 is new generation satellite which has two sensors, Operation Land Manager (OLI) and Thermal Infra-Red Sensor (TIRS). In pre-processing step, there are a geometric correction, radiometric correction, and cropping of the digital images which resulting coordinated geography. Classification uses maximum likelihood estimator algorithm. In segmentation process and classification, grey value spread is into evenly after applying histogram technique. The results of entropy value are7.42 which is the highest of result image classification, then the smallest entropy value in the result of correction mapping are 6.39. The three of them prove that they have enough high entropy value. Then the result of peatlands classification is given overall accuracy value = = 94.0012% and overall kappa value = 0.9230 so the result of classification can be considered to be right.

    Full Text Available Abstract Background The EQ-5D is a generic questionnaire which generates a health profile as well as index scores for health-related quality of life that may be used in cost-utility analysis. Aims of the study To examine validity and responsiveness of the EQ-5D in patients with anxiety disorders. Methods 389 patients with anxiety disorders completed the EQ-5D at baseline and 6-month follow-up. Subjective measures of quality of life (WHOQOL-BREF and psychopathology (BAI, BDI-II, BSQ, ACQ, MI were used for comparison. Validity was analyzed by assessing associations between EQ-5D scores and related other scores. Responsiveness was analyzed by calculating effect sizes of differences in scores between baseline and follow-up for 3 groups indicating more, constant or less anxiety. Meaningful difference scores for shifting to less or more anxiety were derived by means of regression analysis. Results 88.4% of respondents reported problems in at least one of the EQ-5D dimension at baseline; the mean EQ VAS score was 63.8. The EQ-5D dimension most consistently associated with the measures used for comparison was 'anxiety/depression'. EQ VAS and EQ-5D index scores were highly correlated (|r|>0.5 with scores of the WHOQOL-BREF dimensions 'physical', 'mental' and 'overall' as well as BAI and BDI-II. The EQ-5D index tended to be the most responsive score. Standardized meaningful difference scores were not significantly different between EQ VAS, EQ-5D index and measures used for comparison. Conclusions The EQ-5D seems to be reasonably valid and moderately responsive in patients with anxiety disorders. The EQ-5D index may be suitable for calculating QALYs in economic evaluation of health care interventions for patients with anxiety disorders.

    The Tin House Courtyard is a property of the National Capital Commission (NCC) in Ottawa, Canada. The site is located within the `Mile of History', a historical route running from Parliament Hill to the Governor General's residence. Currently, existing assets are under intervention works that include several preservation and renewal actions. Within the broader project, one of the tasks before construction works started was the documentation of the set of facades. The Carleton Immersive Media Studio (CIMS) at Carleton University in Ottawa was commissioned by NCC to conduct the recording of the area. This paper describes the process undertaken from field work to the final deliverable to the client, as well as the issues faced in between. Nowadays, up to date surveying technologies have revolutionized the methodologies for cultural heritage documentation. In this regard, the recording strategy employed encompassed the use of photogrammetry, laser scanner, total station, as well as different pre and post processing software in order to generate the desired outcomes.

    An inter-arm systolic blood pressure difference (IAD) is associated with cardiovascular disease. The aim of this study was to develop and validate the optimal cut-off value of IAD as a predictor of major adverse cardiac events in patients with arteriosclerosis risk factors. From 2009 to 2014, 1076 patients who had at least one cardiovascular risk factor were included in the analysis. We defined 700 randomly selected patients as a development cohort to confirm that IAD was the predictor of cardiovascular events and to determine optimal cut-off value of IAD. Next, we validated outcomes in the remaining 376 patients as a validation cohort. The blood pressure (BP) of both arms measurements were done simultaneously using the ankle-brachial blood pressure index (ABI) form of automatic device. The primary endpoint was the cardiovascular event and secondary endpoint was the all-cause mortality. During a median period of 2.8 years, 143 patients reached the primary endpoint in the development cohort. In the multivariate Cox proportional hazards analysis, IAD was the strong predictor of cardiovascular events (hazard ratio: 1.03, 95% confidence interval: 1.01-1.05, p=0.005). The receiver operating characteristic curve revealed that 5mmHg was the optimal cut-off point of IAD to predict cardiovascular events (p<0.001). In the validation cohort, the presence of a large IAD (IAD ≥5mmHg) was significantly associated with the primary endpoint (p=0.021). IAD is significantly associated with future cardiovascular events in patients with arteriosclerosis risk factors. The optimal cut-off value of IAD is 5mmHg.

    We present a novel assessment tool for measuring biology students' values and experiences across their undergraduate degree program. Our Survey of Teaching Beliefs and Practices for Undergraduates (STEP-U) assesses the extent to which students value skills needed for the workplace (e.g., ability to work in groups) and their experiences with teaching practices purported to promote such skills (e.g., group work). The survey was validated through factor analyses in a large sample of biology seniors (n = 1389) and through response process analyses (five interviewees). The STEP-U skills items were characterized by two underlying factors: retention (e.g., memorization) and transfer (e.g., knowledge application). Multiple linear regression models were used to examine relationships between classroom experiences, values, and student characteristics (e.g., gender, cumulative grade point average [GPA], and research experience). Student demographic and experiential factors predicted the extent to which students valued particular skills. Students with lower GPAs valued retention skills more than those with higher GPAs. Students with research experience placed greater value on scientific writing and interdisciplinary understanding. Greater experience with specific teaching practices was associated with valuing the corresponding skills more highly. The STEP-U can provide feedback vital for designing curricula that better prepare students for their intended postgraduate careers.

    2010-01-01

    Background The purpose of this study was to reduce the number of items, create a scoring method and assess the psychometric properties of the Freedom from Glasses Value Scale (FGVS), which measures benefits of freedom from glasses perceived by cataract and presbyopic patients after multifocal intraocular lens (IOL) surgery. Methods The 21-item FGVS, developed simultaneously in French and Spanish, was administered by phone during an observational study to 152 French and 152 Spanish patients who had undergone cataract or presbyopia surgery at least 1 year before the study. Reduction of items and creation of the scoring method employed statistical methods (principal component analysis, multitrait analysis) and content analysis. Psychometric properties (validation of the structure, internal consistency reliability, and known-group validity) of the resulting version were assessed in the pooled population and per country. Results One item was deleted and 3 were kept but not aggregated in a dimension. The other 17 items were grouped into 2 dimensions ('global evaluation', 9 items; 'advantages', 8 items) and divided into 5 sub-dimensions, with higher scores indicating higher benefit of surgery. The structure was validated (good item convergent and discriminant validity). Internal consistency reliability was good for all dimensions and sub-dimensions (Cronbach's alphas above 0.70). The FGVS was able to discriminate between patients wearing glasses or not after surgery (higher scores for patients not wearing glasses). FGVS scores were significantly higher in Spain than France; however, the measure had similar psychometric performances in both countries. Conclusions The FGVS is a valid and reliable instrument measuring benefits of freedom from glasses perceived by cataract and presbyopic patients after multifocal IOL surgery. PMID:20497555

    With growing populations, economic expansion, and rising standards of living the demand for water is increasing across the globe. Demographic developments and a changing climate will further aggravate the pressure on global water resources. In the EU FP7 project EartH2Observe in-situ data, earth observations, and models will be assimilated to provide a comprehensive reanalysis of the global water resources system, accounting for all components of the global water cycle including information on the impacts of human activities, e.g., through water consumption and man-made reservoirs. Synthesizing as many sources of information as possible bears great potential to improve global water balance estimates and to consequently allow for consistent and informed decisions in water management. One of the modelling suites participating in EartH2Observe is the global hydrological model PCR-GLOBWB (Van Beek et al., 2011) which already accounts for anthropogenic perturbations in the water cycle. Here we present an extensive validation of the latest model version PCR-GLOBWB 2.0 (Sutanudjaja et al., 2014) which comprises dynamic withdrawal, allocation and consumptive use of ground- and surface water resources, irrigation, return flows of unconsumed water to surface water and groundwater resources, and more than 6000 reservoirs of the GRanD database. This study presents the first step towards a full reanalysis merging earth observations, in-situ data and models. We focus on human activities altering the hydrologic cycle over the past 30 years by evaluating PCR-GLOBWB 'natural' and 'humanly-modified' simulations in 0.5°× 0.5° spatial and daily temporal resolution. To this end our model is forced with the newly available WFDEI (WATCH Forcing Data methodology applied to ERA-Interim data) data set. PCR-GLOBWB 2.0 simulations of river discharge, water abstraction and water use are validated against observations from the Global Runoff Data Centre as well as available national and

    Feedback control of total peripheral resistance (TPR) by the arterial and cardiopulmonary baroreflex systems is an important mechanism for short-term blood pressure regulation. Existing methods for measuring this TPR baroreflex mechanism typically aim to quantify only the gain value of one baroreflex system as it operates in open-loop conditions. As a result, the normal, integrated functioning of the arterial and cardiopulmonary baroreflex control of TPR remains to be fully elucidated. To this end, the laboratory of Mukkamala et al. (Mukkamala R, Toska K, and Cohen RJ. Am J Physiol Heart Circ Physiol 284: H947-H959, 2003) previously proposed a potentially noninvasive technique for estimating the closed-loop (dimensionless) gain values of the arterial TPR baroreflex (GA) and the cardiopulmonary TPR baroreflex (GC) by mathematical analysis of the subtle, beat-to-beat fluctuations in arterial blood pressure, cardiac output, and stroke volume. Here, we review the technique with additional details and describe its experimental evaluation with respect to spontaneous hemodynamic variability measured from seven conscious dogs, before and after chronic arterial baroreceptor denervation. The technique was able to correctly predict the group-average changes in GA and GC that have previously been shown to occur following chronic arterial baroreceptor denervation. That is, reflex control by the arterial TPR baroreflex was virtually abolished (GA = -2.1 +/- 0.6 to 0.3 +/- 0.2; P TPR baroreflex more than doubled (GC = -0.7 +/- 0.4 to -1.8 +/- 0.2; P TPR baroreflex functioning in both humans and animals in health and disease.

    The objectives of this study were to evaluate the reliability of Bath ankylosing spondylitis functional index (BASFI) and Bath ankylosing spondylitis disease activity index (BASDAI) in Chinese ankylosing spondylitis (AS) and undifferentiated spondyloarthropathy (USpA) patients. 664 AS patients by the revised New York criteria for AS and 252 USpA patients by the European Spondyloarthropathy Study Group criteria were enrolled. BASDAI and BASFI questionnaires were translated into Chinese. Participants were required to fill in BASFI and BASDAI questionnaires again after 24 h. Moreover, BASDAI and BASFI were compared in AS patients receiving Enbrel or infliximab before and after treatment. For AS group, BASDAI ICC: 0.9502 (95% CI: 0.9330-0.9502, α=0.9702), BASFI ICC: 0.9587 (95% CI: 0.9521-0.9645, α=0.9789). For USpA group, BASDAI ICC: 0.9530 (95% CI: 0.9402-0.9632, α=0.9760), BASFI ICC: 0.9900 (95% CI: 0.9871-0.9922, α=0.9950). In the AS group, disease duration, occipital wall distance, modified Schober test, chest expansion, ESR, and CRP showed significant correlation with BASDAI and BASFI (all P<0.01). In the USpA group, onset age, ESR, and CRP were significantly correlated with BASDAI (all P<0.05), while modified Schober test, ESR, and CRP were significantly associated with BASFI (all P<0.05). The change in BASDAI and BASFI via Enbrel or infliximab treatment showed a significant positive correlation (P<0.01). The two instruments have good reliability and reference value regarding the evaluation of patient's condition and anti-TNF-α treatment response.

    Peripheral venous blood gas (pVBG) analysis in replacement of arterial blood gas (ABG) is limited by the unpredictable differences between arterial and venous values, especially for PCO2 and pH (ΔPCO2 and ΔpH). We hypothesized that, using the theoretical relationship linking SvO2 and blood flow, we could diminish the effect of local circulatory conditions on ΔPCO2 and ΔpH and thereby increase pVBG validity. This was a prospective cross-sectional study performed in emergency patients requiring a blood gas analysis in which ABG and pVBG were performed simultaneously. The data of 50 randomly selected patients (model group) were used for developing two equations to correct PvCO2 and pHv according to the peripheral SvO2 (SpvO2) level. The formulas derived were PvCO2cor = PvCO2 - 0.30 × (75 - SpvO2), and pHvcor = pHv + 0.001 × (75 - SpvO2). The validity of the corrected values was then tested on the remaining population (validation group). There were 281 patients included in the study, mainly for dyspnea. ΔPCO2 and ΔpH were strongly correlated with SpvO2 (r(2) = 0.62 and r(2) = 0.53, respectively, p 45 mm Hg (AUC ROC = 0.96 ± 0.01 vs. 0.89 ± 0.02, p 7.45 (AUC = 0.91 ± 0.02 vs. 0.81 ± 0.04, p arterial abnormality.

    M-MOF-74s were examined for potential applications in ethylene abatement and/or storage/delivery. Due to labile binding resulting from a Jahn-Teller distortion, Cu-MOF-74 exhibits a gradual initial uptake that, in turn, translates into the highest deliverable capacity among the MOFs examined (3.6 mmol g(-1)). In contrast, Co-MOF-74 is the most promising candidate for ethylene abatement due to the sharp uptake at low pressure.

  2. An editorial approach: Mike Nelson’s corridors and The Deliverance and The Patience

    Full Text Available This essay contrasts the contemporary British artist Mike Nelson’s approach to constructing his large, multi-room installations with his approach to editing the numerous artist books that he has produced since 2000. This comparison reveals several compositional symmetries between the two, namely pertaining to narrative non-linearity and meta-fictionality. The logic of montage is shown to similarly underscore both the books and the installations. This essay argues that the corridors connecting the different rooms of Nelson’s installations function in a similar way to the logic of montage: they play an integral role as the support that binds the structure of the installation (its multiple rooms together as a whole. This essay argues that the corridor is the primary viewing framework of the installation for the viewer, and that this vantage point is significant because the necessarily partial vision of the installation from the space of the corridor demonstrates the logic of installation art more broadly. I conclude by mapping the key compositional elements of Nelson’s artist books onto his installations, taking the 2001 work The Deliverance and The Patience as a case study, to show that the books do not exemplify the artwork as with traditional exhibition catalogues, but rather parallel it. That is, a structural continuity is established between these two facets of his work.

    The main goal of the present study was to determine and validate an aquatic Maximum Acceptable Concentration-Environmental Quality Standard (MAC-EQS) value for the agricultural fungicide azoxystrobin (AZX). Assessment factors were applied to short-term toxicity data using the lowest EC50 and after the Species Sensitivity Distribution (SSD) method. Both ways of EQS generation were applied to a freshwater toxicity dataset for AZX based on available data, and to marine toxicity datasets for AZX and Ortiva(®) (a commercial formulation of AZX) obtained by the present study. A high interspecific variability in AZX sensitivity was observed in all datasets, being the copepoda Eudiaptomus graciloides (LC50,48h = 38 μg L(-1)) and the gastropod Gibbula umbilicalis (LC50,96h = 13 μg L(-1)) the most sensitive freshwater and marine species, respectively. MAC-EQS values derived using the lowest EC50 (≤0.38 μg L(-1)) were more protective than those derived using the SSD method (≤3.2 μg L(-1)). After comparing the MAC-EQS values estimated in the present study to the smallest AA-EQS available, which protect against the occurrence of prolonged exposure of AZX, the MAC-EQS values derived using the lowest EC50 were considered overprotective and a MAC-EQS of 1.8 μg L(-1) was validated and recommended for AZX for the water column. This value was derived from marine toxicity data, which highlights the importance of testing marine organisms. Moreover, Ortiva affects the most sensitive marine species to a greater extent than AZX, and marine species are more sensitive than freshwater species to AZX. A risk characterization ratio higher than one allowed to conclude that AZX might pose a high risk to the aquatic environment. Also, in a wider conclusion, before new pesticides are approved, we suggest to improve the Tier 1 prospective Ecological Risk Assessment by increasing the number of short-term data, and apply the SSD approach, in order to ensure the safety of

    Background: Preanalytical factors affects different biochemical parameters. Therefore reference intervals are recommended to apply to rules of standardization that state that blood samples should be taken in the morning after 15 min rest. However, both hospital and patients have a wish to minimize...... waiting time prior to blood sampling. Moreover, some parameters have diurnal variation and since there is a growing desire to expand opening hours in the clinics this variation is worth investigating further. Therefore our aim is to test whether the reference intervals of albumin and thyrotropin are valid...... electronically using Q-MATIC Suite. Impact of resting time and time of day on thyreotropin and albumin values was analyzed using a simple linear regression. The "maximum allowable bias" was used as quality indicator for the reference interval. Results: Using linear regression we found significant diurnal...

    Full Text Available This study investigated the added value, i.e. discriminative and concurrent validity and reproducibility, of an eye-hand coordination test relevant to table tennis as part of talent identification. Forty-three table tennis players (7-12 years from national (n = 13, regional (n = 11 and local training centres (n = 19 participated. During the eye-hand coordination test, children needed to throw a ball against a vertical positioned table tennis table with one hand and to catch the ball correctly with the other hand as frequently as possible in 30 seconds. Four different test versions were assessed varying the distance to the table (1 or 2 meter and using a tennis or table tennis ball. 'Within session' reproducibility was estimated for the two attempts of the initial tests and ten youngsters were retested after 4 weeks to estimate 'between sessions' reproducibility. Validity analyses using age as covariate showed that players from the national and regional centres scored significantly higher than players from the local centre in all test versions (p<0.05. The tests at 1 meter demonstrated better discriminative ability than those at 2 meter. While all tests but one had a positive significant association with competition outcome, which were corrected for age influences, the version with a table tennis ball at 1 meter showed the highest association (r = 0.54; p = 0.001. Differences between the first and second attempts were comparable for all test versions (between -8 and +7 repetitions with ICC's ranging from 0.72 to 0.87. The smallest differences were found for the test with a table tennis ball at 1 meter (between -3 and +3 repetitions. Best test version as part of talent identification appears to be the version with a table tennis ball at 1 meter regarding the psychometric characteristics evaluated. Longitudinal studies are necessary to evaluate the predictive value of this test.

    The basic objective of iTREN-2030 is to extend the forecasting and assessment capabilities of the TRANS-TOOLS transport model to the new policy issues arising from the technology, environment and energy fields. This is achieved by couplin the TRANS-TOOLS model with three other models, ASTRA, POLES and TREMOVE covering these new policy issues. The TRANS-TOOLS transport network model has been developed to constitute the reference tool for supporting transport policy in the EU and currently is being developed in several European projects. The scenario set-up to be developed in iTREN-2030 has been modified, so that the projects develops a reference scenario and an integrated scenario. For the reference scenario, the three other modelling tools are harmonised with TRANS-TOOLS and made consistent with each other. This results in a coherent scenario for Europe until 2030 for technology, transport, energy, environment and economic development. The integrated scenario will consider the changing framework conditions until 2030, inparticular the policy pressure coming from climate policy and the increasing scarcity of fossil fuels as well as the impact of the financial and economic crisis. Within the iTREN-2030 project, the overall objective of Work Package 4 (WP4) producing tis deliverable is to develop the reference scenario for the quantitative projections using the four modelling tools involved in the project. The main aims of WP4 are to (a) define a consistent framework for using the different tools in an integrated way; (b) calibrate models with exchanged input to a coherent joint reference; (c) implement external input from WP3 and running models for projections; (d) produce output procedures and templates to facilitate assessment in WP5.

  8. Transfer factor (diffusing capacity) standardized for alveolar volume: validation, reference values and applications of a new linear model to replace KCO (TL/VA)

    Transfer factor (TL) varies with alveolar volume (VA), but not in the manner implied by the carbon monoxide transfer coefficient (KCO (TL/VA)). This paper considers two other simple models (one linear and one exponential) which might standardize TL for VA, and asks the questions: 1) Is either model valid? 2) What are appropriate reference values? and 3) Will the model be useful? The relationship of TL to VA within subjects at different depths of inspiration, and between subjects having lungs of different sizes, were measured and compared. The subjects were asymptomatic, nonsmoking, Caucasian adults, including 31 males assessed in the laboratory and 503 male and female participants in population studies. The linear partial regression coefficients of TL on VA (L corrected for body temperature, atmospheric pressure and water saturation (BTPS)) standardized for height (H) in metres, were similar within- and between-subjects; the coefficients applied over a wide range of values for VA. This was not the case for the exponential model. The resulting reference equations in SI units for males and females were: TL = 11.52 H + 2.72 VA.H-2 - 0.051 Age -12.35. RSD 1.17; and TL = 4.87 H + 2.29 VA.H-2 - 0.019 Age -3.03. RSD 0.92, respectively. The residual standard deviations (RSD) about the new relationships were less than in other series. The new linear model could account for much of the variation between different published reference values for TL; it could be useful clinically, in circumstances when VA deviates from the norm. The model does not explain differences in TL associated with gender. Inclusion of VA.H-2 as a covariate in the reference equation for transfer factor, in addition to age and height, improves the accuracy of prediction of normal transfer factor compared with current reference values; its use suggests that some of the differences between published values is due to the volume term. The equations can be used clinically, and eliminate the need for carbon

    2010-12-15

    A ZephIR prototype wind lidar manufactured by QinetiQ was mounted on the nacelle of a Vestas V27 wind turbine and measurements of the incoming wind flow towards the rotor of the wind turbine were acquired for approximately 3 months (April - June 2009). The objective of this experiment was the investigation of the turbulence attenuation induced in the lidar measurements. In this report are presented results from data analysis over a 21-hour period (2009-05-05 12:00 - 2009-05-06 09:00). During this period the wind turbine was not operating and the line-of-sight of the lidar was aligned with the wind direction. The analysis included a correlation study between the ZephIR lidar and a METEK sonic anemometer. The correlation analysis was performed using both 10 minutes and 10 Hz wind speed values. The spectral transfer function which describes the turbulence attenuation, which is induced in the lidar measurements, was estimated by means of spectral analysis. An attempt to increase the resolution of the wind speed measurements of a cw lidar was performed, through the deconvolution of the lidar signal. A theoretical model of such a procedure is presented in this report. A simulation has validated the capability of the algorithm to deconvolve and consequently increase the resolution of the lidar system. However the proposed method was not efficient when applied to real lidar wind speed measurements, probably due to the effect, that the wind direction fluctuations along the lidar's line-of-sight have, on the lidar measurements.

    At local level, public support has proven crucial to the implementation of CO2 capture and storage (CCS) demonstration projects. Whereas no method exists to guarantee public acceptability of any project, a constructive stakeholder and community engagement process does increase the likelihood thereof. This deliverable is a follow-up to deliverable D8.1 'Social site characterisation'. Social site characterisation can be used as an instrument to explore, plan and evaluate a process of active and constructive local stakeholder and citizen engagement in a prospective CCS project as a parallel activity to technical site characterisation. It serves as an analytical tool to describe the local social circumstances in the area and to design and evaluate stakeholder and community engagement efforts with the aims of building trust and raising public awareness. Using results from the social site characterisation of the area, the present deliverable focuses on the second purpose. It presents results from public engagement activities designed to raise public awareness and inform public opinion of a prospective CCS site in Poland (onshore) and the UK (offshore): focus conferences. Furthermore, by initiating an enhanced cooperation in planning of new storage sites between project developers, authorities and the local public, focus conferences aim to serve as a 'hinge' between social site characterisation as a research effort and application to real-life project settings. The focus conferences are part of a range of public engagement activities including the setup of public information websites on generic and site-specific CCS, information meetings. A second survey eventually shall evaluate the results of the public engagement activities. The aim of the focus conferences was to raise public awareness and assist public opinion forming processes of a prospective CCS site in Poland (onshore) and the UK (offshore). At the same time, it aimed to present and test a

    The early detection of upper limb complications is important in women operated on for breast cancer. The "FACT-B+4-UL" questionnaire, a specific variant of the Functional Assessment of Cancer Therapy-Breast (FACT-B) is available among others to measure the upper limb function. The Spanish version of the upper limb subscale of the FACT-B+4 was validated in a prospective cohort of 201 women operated on for breast cancer (factor analysis, internal consistency, test-retest reliability, construct validity and sensitivity to change were determined). Its predictive capacity of subsequent lymphoedema and other complications in the upper limb was explored using logistic regression. This subscale is unifactorial and has a great internal consistency (Cronbach's alpha: 0.87), its test-retest reliability and construct validity are strong (intraclass correlation coefficient: 0.986; Pearson's R with "Quick DASH": 0.81) as is its sensitivity to change. It didn't predict the onset of lymphedema. Its predictive capacity for other upper limb complications is low. FACT-B+4-UL is useful in measuring upper limb disability in women surgically treated for breast cancer; but it does not predict the onset of lymphoedema and its predictive capacity for others complications in the upper limb is low.

    Wounds that exhibit delayed healing add extraordinary clinical, economic, and personal burdens to patients, as well as to increasing financial costs to health systems. New interventions designed to ease such burdens for patients with cancer, renal, or ophthalmologic conditions are often cleared for approval by the U.S. Food and Drug Administration (FDA) using multiple endpoints but the requirement of complete healing as a primary endpoint for wound products impedes FDA clearance of interventions that can provide other clinical or patient-centered benefits for persons with wounds. A multidisciplinary group of wound experts undertook an initiative, in collaboration with the FDA, to identify and content validate supporting FDA criteria for qualifying wound endpoints relevant to clinical practice (CP) and patient-centered outcomes (PCO) as primary outcomes in clinical trials. As part of the initiative, a research study was conducted involving 628 multidisciplinary expert wound clinicians and researchers from 4 different groups: the interdisciplinary core advisory team; attendees of the Spring 2015 Symposium on Advanced Wound Care (SAWC); clinicians employed by a national network of specialty clinics focused on comprehensive wound care; and Association for the Advancement of Wound Care (AAWC) and Wound Healing Society (WHS) members who had not previously completed the survey. The online survey assessed 28 literature-based wound care endpoints for their relevance and importance to clinical practice and clinical research. Fifteen of the endpoints were evaluated for their relevance to improving quality of life. Twenty-two endpoints had content validity indexes (CVI) ≥ 0.75, and 15 were selected as meriting potential inclusion as additional endpoints for FDA approval of future wound care interventions. This study represents an important first step in identifying and validating new measurable wound care endpoints for clinical research and practice and for regulatory

  13. Validation of odor concentration from mechanical-biological treatment piles using static chamber and wind tunnel with different wind speed values.

    Science.gov (United States)

    Szyłak-Szydłowski, Mirosław

    2017-09-01

    The basic principle of odor sampling from surface sources is based primarily on the amount of air obtained from a specific area of the ground, which acts as a source of malodorous compounds. Wind tunnels and flux chambers are often the only available, direct method of evaluating the odor fluxes from small area sources. There are currently no widely accepted chamber-based methods; thus, there is still a need for standardization of these methods to ensure accuracy and comparability. Previous research has established that there is a significant difference between the odor concentration values obtained using the Lindvall chamber and those obtained by a dynamic flow chamber. Thus, the present study compares sampling methods using a streaming chamber modeled on the Lindvall cover (using different wind speeds), a static chamber, and a direct sampling method without any screens. The volumes of chambers in the current work were similar, ~0.08 m(3). This study was conducted at the mechanical-biological treatment plant in Poland. Samples were taken from a pile covered by the membrane. Measured odor concentration values were between 2 and 150 ouE/m(3). Results of the study demonstrated that both chambers can be used interchangeably in the following conditions: odor concentration is below 60 ouE/m(3), wind speed inside the Lindvall chamber is below 0.2 m/sec, and a flow value is below 0.011 m(3)/sec. Increasing the wind speed above the aforementioned value results in significant differences in the results obtained between those methods. In all experiments, the results of the concentration of odor in the samples using the static chamber were consistently higher than those from the samples measured in the Lindvall chamber. Lastly, the results of experiments were employed to determine a model function of the relationship between wind speed and odor concentration values. Several researchers wrote that there are no widely accepted chamber-based methods. Also, there is still a need

    To determine the negative predictive value of sonographically guided 14-gauge core needle biopsy of breast masses, with detailed analysis of any false-negative cases. We reviewed 669 cases of sonographically guided 14-gauge core needle biopsies that had benign pathologic findings. Given a benign pathology on core biopsy, true-negatives had either benign pathology on surgical excision or at least 2 years of stable imaging and/or clinical follow-up; false-negatives had malignant histology on surgical excision. Follow-up was available for 339 breast lesions; 117 were confirmed to be benign via surgical excision, and 220 were stable after 2 years or more of imaging or clinical follow-up (mean follow-up time 33.1 months, range 24-64 months). The negative predictive value was determined to be 99.4%. There were 2 false-negative cases, giving a false-negative rate of 0.1%. There was no delay in diagnosis in either case because the radiologist noted discordance between imaging and core biopsy pathology, and recommended surgical excision despite the benign core biopsy pathology. Sonographically guided 14-gauge core needle biopsy provides a high negative predictive value in assessing breast lesions. Radiologic/pathologic correlation should be performed to avoid delay in the diagnosis of carcinoma.

  15. Greater decision-making competence is associated with greater expected-value sensitivity, but not overall risk taking: An examination of concurrent validity

    2015-05-01

    Full Text Available Decision-making competence reflects individual differences in the susceptibility to decision-making errors, measured using tasks common from behavioral decision research (e.g., framing effects, under/overconfidence, following decision rules. Prior research demonstrates that those with higher decision-making competence report lower incidence of health-risking and antisocial behaviors, but there has been less focus on intermediate mechanisms that may impact real-world decisions, and, in particular, those implicated by normative models. Here we test the associations between measures of youth decision-making competence (Y-DMC and one such mechanism, the degree to which individuals make choices consistent with maximizing expected value (EV. Using a task involving hypothetical gambles, we find that greater EV sensitivity is associated with greater Y-DMC. Higher Y-DMC scores are associated with (a choosing risky options when expected value favors those options and (b avoiding risky options when expected value favors a certain option. This relationship is stronger for gambles that involved potential losses. The results suggest that Y-DMC captures decision processes consistent with standard normative evaluations of risky decisions.

    This report presents near-term station cost results and discusses cost trends of different station types. It compares various vehicle rollout scenarios and projects realistic near-term station utilization values using the station infrastructure rollout in California as an example. It describes near-term market demands and matches those to cost-effective station concepts. Finally, the report contains detailed designs for five selected stations, which include piping and instrumentation diagrams, bills of materials, and several site-specific layout studies that incorporate the setbacks required by NFPA 2, the National Fire Protection Association Hydrogen Technologies Code. This work identified those setbacks as a significant factor affecting the ability to site a hydrogen station, particularly liquid stations at existing gasoline stations. For all station types, utilization has a large influence on the financial viability of the station.

    Medical imaging plays a key role in guiding treatment of traumatic brain injury (TBI) and for diagnosing intracranial hemorrhage; most commonly rapid computed tomography (CT) imaging is performed. Outcomes for patients with TBI are variable and difficult to predict upon hospital admission. Quantitative outcome scales (e.g., the Marshall classification) have been proposed to grade TBI severity on CT, but such measures have had relatively low value in staging patients by prognosis. Herein, we examine a cohort of 1,003 subjects admitted for TBI and imaged clinically to identify potential prognostic metrics using a "big data" paradigm. For all patients, a brain scan was segmented with multi-atlas labeling, and intensity/volume/texture features were computed in a localized manner. In a 10-fold cross-validation approach, the explanatory value of the image-derived features is assessed for length of hospital stay (days), discharge disposition (five point scale from death to return home), and the Rancho Los Amigos functional outcome score (Rancho Score). Image-derived features increased the predictive R(2) to 0.38 (from 0.18) for length of stay, to 0.51 (from 0.4) for discharge disposition, and to 0.31 (from 0.16) for Rancho Score (over models consisting only of non-imaging admission metrics, but including positive/negative radiological CT findings). This study demonstrates that high volume retrospective analysis of clinical imaging data can reveal imaging signatures with prognostic value. These targets are suited for follow-up validation and represent targets for future feature selection efforts. Moreover, the increase in prognostic value would improve staging for intervention assessment and provide more reliable guidance for patients.

    This report is Deliverable 4.1 of the EU project 'Wind Power Inte-gration in Liberalised Electricity Markets' (WILMAR) and de-scribes the application of two policy instruments, Tradable Emis-sions Permits (TEPs) and Tradable Green Certificates (TGCs) for electricity produced from renewable energy sources in the European Union and the implications for implementation in the Wilmar model. The introduction of a common emission-trading system in the EU is expected to have an upward effect on the spot prices at the electric-ity market. The variations of the spot price imply that some types of power generation may change the situation from earning money to losing money despite the increasing spot price. Heavy restrictions on emissions penalise the fossil-fuelled technologies significantly, and the associated increase in the spot price need not compensate for this. Therefore, a market of TEPs is expected to have a signifi-cant influence on the electricity spot price. However, the expected price level of TEPs are met with great uncertainty and a study of a number of economical studies shows a price span between zero and 270 USD per ton of CO{sub 2} depending on the participation or non-participation of countries in the scheme. The price-determination at the TGC market is expected to be closely related to the price at the power spot market as the RE-producers of electricity will have expectations to the total price paid for the energy produced, i.e., for the price of electricity at the spot market plus the price per kWh obtained at the green certificate mar-ket. In the Wilmar model, the TGC market can either be handled exogenously, i.e., the increase in renewable capacity and an average annual TGC price are determined outside the model, or a simple TGC module is developed, including the long-term supply functions for the most relevant renewable technologies and an overall TGC quota. Both solutions are rather simple, but to develop a more ad-vanced model for the TGC

    This report describes the results of the last stage of the in-depth social site characterisation activities at two prospective CCS sites as part of the SiteChar project: a CCS onshore site and a CCS offshore site. The onshore site is the Zalecze and Zuchlow site application (Poland - WP5) and the offshore site is the North Sea Moray Firth site (UK - WP3). This deliverable describes the results from a repeated quantitative measurement of local awareness, knowledge, and perceptions of CCS at both sites using representative surveys. For comparison and discussion of all SiteChar WP8 results we refer to the final summary report D8.5. The 2nd survey showed some interesting results. First of all, awareness of CCS was still very low. While in the UK around half of the respondents had at least heard of local plans for CCS, in Poland this was only 21%. It seems that awareness in the UK was mostly induced by specific plans in the area that were abandoned in the course of the SiteChar project. Second, it seems that on the whole the local publics were rather positive about CCS. Most respondents expected a positive impact of CCS on the region. In the UK, arguments for that were mainly economic, while in Poland arguments were mainly related to environmental concerns. Although there are some worries about risks of leakage, especially at the onshore site in Poland, people think that authorities will properly regulate CCS and monitor the safety of CCS. Expectations were mostly that it would be good for the country and that it will help reach international targets for CO2 reduction and buy time to develop renewable energy. Respondents seemed uncertain about the costs of using CCS and whether the technique is ready for widespread use. Especially in Poland people seemed to agree that CCS is essential for tackling climate change. Most differences between the two sites may be attributed to the proximity of the site to the local community. The Polish site is onshore and therefore much

    Purpose: To study the influence of clipping PTV from body contour on plan quality and deliverability in build-up region for superficial target. Methods: Five previously treated patients of post-operative carcinoma of parotid were re-planned for IMRT (6MV X-rays, sliding window technique, five fields and 60Gy/30 fractions) using eclipse treatment planning system (TPS) by keeping dose volume constraints and all other parameters constant, only PTV was clipped from body contour by 0mm, 1mm, 2mm and 3mm respectively. Planned fluence was transferred to previously scanned solid water phantom by placing I’matriXX array at 0.5cm depth (2mm slab+3mm inherent). Fluence was delivered by Varian CL2300C/D linac at 99.5cm source to detector distance. Measured fluence was compared with TPS dose plane using 2D gamma evaluation using 3%/3mm DTA criteria. Total MU (monitor unit) required to deliver a plan was also noted. For plan quality, PTV, maximum-dose, minimum-dose, coverage index (CI=PTV volume covered by prescription dose/PTV) and heterogeneity index HI=D5/D95 were analyzed using dose volume histogram (DVH). Results: The Result of gamma function analysis for I’matriXX and TPS were 97.63±1.79%, 97.48±0.99, 98.08±0.89% and 98.01±0.78% at 0.5cm build-up depth for 0, 1, 2 and 3mm PTV clipping, respectively. I’matriXX measured dose was higher compared to TPS. Total MU required for delivering a plan were 552±61, 503±47, 436±24 and 407±22. Maximum-dose to PTV was 6635.80±62.01cGy, 6635.80±40.60cGy, 6608.43±51.07cGy and 6564.20±28.51cGy. Similarly, minimum-dose to PTV was 3306.23±458.56cGy, 3546.57±721.01cGy, 4591.43±298.81cGy and 4861.90±412.40cGy. CI was 0.9347±0.020, 0.9398±0.021, 0.9448±0.022 and 0.9481±0.021. Similarly, HI was 1.089±0.015, 1.084±0.014, 1.078±0.009 and 1.074±0.008 for 0, 1, 2 and 3mm PTV clipping, respectively. Conclusion: Gamma function analysis resulted in almost similar results. However, I’matriXX was overestimating the dose

    Recording Cultural Heritage objects using terrestrial laserscanning becomes more and more popular over the last years. Since terrestrial Laserscanning System (TLS) Manufacturers have strongly increased the amount and speed of data captured with a single scan at each system upgrade and cutting down system costs the use of TLS Systems for recording cultural heritage is an option for recording worth to think about beside traditional methods like Photogrammetric. TLS Systems can be a great tool for capturing complex cultural heritage object within a short amount of time beside the traditional methods but can be a nightmare to handle for further process if not used right while capturing. Furthermore TLS Systems still have to be recognized as survey equipment, even though some of the manufactures promote them as everyday tool. They have to be used in an intelligent way having in mind the clients and the individual cultural objects needs. Thus the efficient way to use TLS Systems for data recording becomes a relevant topic to deal with the huge Amount of data the Systems collect while recording. Already small projects can turn into huge Pointcloud Datasets that End user, like Architects or Archaeologist neither can't deal with as their technical equipment doesn't fit the requirements of the Dataset nor do they have the software tools to use the Data as the current software tools still are high prized. Even the necessary interpretation of the Dataset can be a tough task if the people who have to work on with the Pointcloud aren't educated right in order to understand TLS and the results it creates. The use of TLS Systems has to have in mind the project requirements of the individual Heritage Object, like the required accuracy, standards for Levels of Details (e.g. "Empfehlungen für die Baudokumentation, Günther Eckstein, Germany"), the required kind of Deliverables (Visualization, 2D Drawings, True Deformation Drawings, 3D Models, BIM or 4D - Animations) as well as the

    The aim of this study was to evaluate the significance of the Ki67 labeling index and p53 status as prognostic and predictive indicators of operable estrogen receptor (ER)-positive and human epidermal growth factor receptor 2 (HER2)-negative breast cancer. Among 697 consecutive patients with primary breast cancer who underwent curative surgery between 2002 and 2013, 308 patients with ER-positive and HER2-negative breast cancer were assessed. The results of the multivariate Cox analysis demonstrated that a high Ki67 labeling index was significantly associated with a short recurrence-free interval (RFI) (p=0.004) and was marginally associated with a worse overall survival (p=0.074). A positive p53 status was not associated with worse outcomes. To validate the cut-off values of the Ki67 labeling index for identifying patients who may benefit from additional chemotherapy, prognostic factors were investigated in breast cancer patients treated postoperatively with endocrine therapy alone. Analysis of receiver operating characteristic curves demonstrated that a Ki67 labeling index cut-off of 20.0% was optimal for predicting recurrence among patients who did not receive adjuvant chemotherapy. The 5-year RFIs for patients with Ki67 <20 and ≥20% were 97.2 and 86.6%, respectively (p=0.0244). A high Ki67 labeling index (≥20%) was significantly associated with large tumors (p<0.01), lymph node metastasis (p=0.0236) and positive p53 status (p<0.001). The univariate analysis demonstrated that Ki67 labeling index ≥20%, lymph node metastasis and progesterone receptor negativity were significant worse prognostic factors for RFI (p=0.0333, 0.0116 and 0.0573, respectively). The Ki67 labeling index was found to be a useful prognostic factor in patients with ER-positive and HER2-negative breast cancer and the cut-off values of the Ki67 labeling index for making a decision regarding adjuvant treatment were validated.

    The Plug-In Hybrid Electric Vehicle (PHEV) Value Propositions Workshop held in Washington, D.C. in December 2007 served as the Task 1 Milestone for this study. Feedback from all five Workshop breakout sessions has been documented in a Workshop Summary Report, which can be found at www.sentech.org/phev. In this report, the project team compiled and presented a comprehensive list of potential value propositions that would later serve as a 'grab bag' of business model components in Task 2. After convening with the Guidance and Evaluation Committee and other PHEV stakeholders during the Workshop, several improvements to the technical approach were identified and incorporated into the project plan to present a more realistic and accurate case study and evaluation. The assumptions and modifications that will have the greatest impact on the case study selection process in Task 2 are described in more detail in this deliverable. The objective of Task 2 is to identify the combination of value propositions that is believed to be achievable by 2030 and collectively hold promise for a sustainable PHEV market by 2030. This deliverable outlines what the project team (with input from the Committee) has defined as its primary scenario to be tested in depth for the remainder of Phase 1. Plans for the second and third highest priority/probability business scenarios are also described in this deliverable as proposed follow up case studies in Phase 2. As part of each case study description, the proposed utility system (or subsystem), PHEV market segment, and facilities/buildings are defined.

    2017-01-01

    Introduction While anxiety is a major public health problem in adults with arthritis and other rheumatic diseases (AORD), the effects of exercise on anxiety in adults are not well established despite numerous studies on this topic. The purpose of this study is to conduct a systematic review with an aggregate data meta-analysis to determine the effects of community-deliverable exercise interventions (aerobic, strength training or both) on anxiety in adults with AORD. Methods and analysis Randomised controlled exercise intervention trials ≥4 weeks and published in any language up to 31 December 2016 will be included. Studies will be retrieved by searching 8 electronic databases, cross-referencing and expert review. Dual selection and abstraction of data will occur. The primary outcome will be changes in anxiety. Risk of bias will be assessed using the Cochrane risk of bias assessment instrument while confidence in the cumulative evidence will be assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) instrument. Standardised effect sizes for anxiety will be calculated from each study and then pooled using the inverse variance heterogeneity (IVhet) model. Meta-regression based on the IVhet model will be used to examine the relationship between changes in anxiety and selected covariates. Dissemination The results of this study will be presented at a professional conference and published in a peer-reviewed journal. Trial registration number CRD42016048728. PMID:28264834

    Purpose - The purpose of the paper is to explicate how connectedness of relationships results in varying value potentials of triads. Design/methodology/approach - First connectedness is re-described as an actor-perceived and actor-interpreted phenomenon. The re-description is used to theorize...... the triad value function. Next, the applicability and validity of the concept is examined in a case study of four closed vertical supply chain triads. Findings - The case study demonstrates that the triad value function facilitates the analysis and understanding of an apparent paradox; that distributors...... are not dis-intermediated in spite of their limited contribution to activities in the triads. The results indicate practical adequacy of the triad value function. Research limitations/implications - The triad value function is difficult to apply in the study of expanded networks as the number of connections...

    In 1996, at the request of the Government of the Islamic Republic of Mauritania, a team of U.S. Geological Survey (USGS) scientists produced a strategic plan for the acquisition, improvement and modernization of multidisciplinary sets of data to support the growth of the Mauritanian minerals sector and to highlight the geological and mineral exploration potential of the country. In 1999, the Ministry of Petroleum, Energy, and Mines of the Islamic Republic of Mauritania implemented a program for the acquisition of the recommended basic geoscientific information, termed the first Projet de Renforcement Institutionnel du Secteur Minier (Project for Institutional Capacity Building in the Mining Sector, PRISM-I). As a result of the PRISM-I efforts, a great deal of new geological, geophysical, geochemical, remote sensing, and hydrological data became available for evaluation and synthesis. However, the Ministry of Petroleum, Energy, and Mines recognized that additional work was required to extract the full benefit of the data before it could be of greatest use to the international community and of benefit to the Mauritanian minerals and development sector.

  4. The value of value congruence.

    Edwards, Jeffrey R; Cable, Daniel M

    2009-05-01

    Research on value congruence has attempted to explain why value congruence leads to positive outcomes, but few of these explanations have been tested empirically. In this article, the authors develop and test a theoretical model that integrates 4 key explanations of value congruence effects, which are framed in terms of communication, predictability, interpersonal attraction, and trust. These constructs are used to explain the process by which value congruence relates to job satisfaction, organizational identification, and intent to stay in the organization, after taking psychological need fulfillment into account. Data from a heterogeneous sample of employees from 4 organizations indicate that the relationships that link individual and organizational values to outcomes are explained primarily by the trust that employees place in the organization and its members, followed by communication, and, to a lesser extent, interpersonal attraction. Polynomial regression analyses reveal that the relationships emanating from individual and organizational values often deviated from the idealized value congruence relationship that underlies previous theory and research. The authors' results also show that individual and organizational values exhibited small but significant relationships with job satisfaction and organizational identification that bypassed the mediators in their model, indicating that additional explanations of value congruence effects should be pursued in future research.

    2008-09-06

    The four experiments, ALICE, ATLAS, CMS and LHCb are currently under constructionat CERN. They will study the products of proton-proton collisions at the Large Hadron Collider. All experiments are equipped with sophisticated tracking systems, unprecedented in size and complexity. Full exploitation of both the inner detector andthe muon system requires an accurate alignment of all detector elements. Alignmentinformation is deduced from dedicated hardware alignment systems and the reconstruction of charged particles. However, the system is degenerate which means the data is insufficient to constrain all alignment degrees of freedom, so the techniques are prone to converging on wrong geometries. This deficiency necessitates validation and monitoring of the alignment. An exhaustive discussion of means to validate is subject to this document, including examples and plans from all four LHC experiments, as well as other high energy experiments.

    2014-08-01

    SANSMIC is solution mining software that was developed and utilized by SNL in its role as geotechnical advisor to the US DOE SPR for planning purposes. Three SANSMIC leach modes - withdrawal, direct, and reverse leach - have been revalidated with multiple test cases for each mode. The withdrawal mode was validated using high quality data from recent leach activity while the direct and reverse modes utilized data from historical cavern completion reports. Withdrawal results compared very well with observed data, including the location and size of shelves due to string breaks with relative leached volume differences ranging from 6 - 10% and relative radius differences from 1.5 - 3%. Profile comparisons for the direct mode were very good with relative leached volume differences ranging from 6 - 12% and relative radius differences from 5 - 7%. First, second, and third reverse configurations were simulated in order to validate SANSMIC over a range of relative hanging string and OBI locations. The first-reverse was simulated reasonably well with relative leached volume differences ranging from 1 - 9% and relative radius differences from 5 - 12%. The second-reverse mode showed the largest discrepancies in leach profile. Leached volume differences ranged from 8 - 12% and relative radius differences from 1 - 10%. In the third-reverse, relative leached volume differences ranged from 10 - 13% and relative radius differences were %7E4 %. Comparisons to historical reports were quite good, indicating that SANSMIC is essentially the same as documented and validated in the early 1980's.

  8. Validation of Serious Games

    2015-09-01

    Full Text Available The application of games for behavioral change has seen a surge in popularity but evidence on the efficacy of these games is contradictory. Anecdotal findings seem to confirm their motivational value whereas most quantitative findings from randomized controlled trials (RCT are negative or difficult to interpret. One cause for the contradictory evidence could be that the standard RCT validation methods are not sensitive to serious games’ effects. To be able to adapt validation methods to the properties of serious games we need a framework that can connect properties of serious game design to the factors that influence the quality of quantitative research outcomes. The Persuasive Game Design model [1] is particularly suitable for this aim as it encompasses the full circle from game design to behavioral change effects on the user. We therefore use this model to connect game design features, such as the gamification method and the intended transfer effect, to factors that determine the conclusion validity of an RCT. In this paper we will apply this model to develop guidelines for setting up validation methods for serious games. This way, we offer game designers and researchers handles on how to develop tailor-made validation methods.

    2017-02-01

    The Quick-EBP-VIK is a new instrument for measuring nurses' value, implementation, and knowledge of EBP. Psychometric testing was conducted in two parts. Part 1 describes the tool development and validity testing which resulted in the development of a 25-item survey after receiving ≥0.80 Item-Level Content Validity Index for both clarity and relevance. Part 2 describes psychometric testing was necessary to assess additional types of validity and reliability. The purpose of this paper is to further describe the psychometric testing of the Quick-EBP-VIK survey instrument. This descriptive study was designed to assess test-retest reliability, internal consistency and construct validity via a web-based survey. The survey instrument was e-mailed to all nurses at the study hospital. Nurses who responded to the first survey (Wave 1) received another e-mail invitation to complete the survey instrument again (Wave 2) for the purpose of assessing the test-retest reliability of the instrument. A total of 1,177 deliverable e-mails were sent to all nursing staff at one free standing pediatric hospital with Magnet(®) designation in the northeast. A total of 382 nurses returned completed surveys, indicating a 32.5% response rate for Wave 1. A total of 131 nurses responded to Wave 2 indicating a response rate of 34.3%. The intraclass correlation coefficients for the items included in the final instrument ranged from 0.43 to 0.80 and were deemed sufficient. These represent a sufficient intraclass correlation coefficient. The Cronbach's Alpha values for each of the three domains are all higher than 0.7 indicating that the items of each of the measurement dimension are internally consistent. However, the composite reliability of the third domain was slightly lower than 0.7 when using Raykov's Rho. The Quick-EBP-VIK instrument has gone through rigorous comprehensive testing and has demonstrated good psychometric properties. © 2016 Sigma Theta Tau International.

    2008-11-15

    This report represents Deliverable D.3.2 of Work Package 3 in the Night Wind project. The aim of this Work Package was to simulate a cold store (or number of cold stores) within a power system where there is a high degree of wind power penetration. The Night Wind Control System, developed as part of Work Package 5, was to be integrated into the simulations so that the wind power could be 'stored' in the cold store with maximum benefit to the electrical network, utility or cold store owner. To this end, the following have been accomplished: 1) The Night Wind concept has been described in terms of demand side management. 2) Input requirements and data have been specified and collected. Measured data from the existing cold store facility of Partner Logistics has been analysed. 3) Component models for the simulations (including the cold store model itself) have been developed for the simulation platform, IPSYS. 4) The Night Wind Control System (NWCS) from Work Package 5 has been developed so that it finishes computations within two minutes. 5) Controllers including the NWCS) have been operated with the cold store model within IPSYS. 6) Simulations have been performed with the cold store model and an increasing penetration of wind power. This report presents the results of the work undertaken in Work Package 3 which would have benefited from the additional time requested at the project meeting in March 2008, however, this extension of time was not granted. Nevertheless, the work that was possible is considered significantly complete, although it is acknowledged that there has been a delay in the presentation of this report. It should be noted that it was not possible to address the new aspects of Task 3.7 'Verification of simulation results' as there was no implementation of the night wind concept at the demonstration site (Task 7). Verification of the simulation of the present system has, naturally, been carried out and described in this report. (ln)

    A hydrogeologic study was conducted to support mineral-resource assessment activities in Mauritania, Africa. Airborne magnetic depth estimates reveal two primary groundwater basins: the porous coastal Continental Terminal Basin (fill deposits); and the interior, fractured interior Taoudeni Basin. In the Continental Terminal Basin, there is uniform vertical recharge and localized discharge that is coincident with groundwater pumping at Nouakchott. This pumping center induces eastward flow of groundwater from the Atlantic Ocean resulting in a salinity gradient that diminishes quality over 100 km. Groundwater also flows southward into the basin from Western Sahara. By contrast, an interbasin exchange occurs as fresh groundwater flows westward from the Taoudeni Basin. In the Taoudeni Basin, zones of local recharge occur in three areas: northwest at the edge of the Rgueïbat Shield; at the city of Tidjikja; and near the center of the basin. Groundwater also flows across international boundaries: northward into Western Sahara and westward into Mali. At the southern country boundary, the Senegal River serves as both a source and sink of fresh groundwater to the Continental Terminal and Taoudeni basins. Using a geographical information system, thirteen hydrogeologic units are identified based on lateral extent and distinct hydraulic properties for future groundwater model development. Combining this information with drilling productivity, groundwaterquality, and geophysical interpretations (fracturing and absence of subsurface dikes) three potential water-resource development targets were identified: sedimentary rocks of the Jurassic, Cretaceous, and Quaternary Periods; sedimentary rocks of Cambrian and Ordovician Periods; and sedimentary rocks of Neoproterozoic age.

  17. Real-time infrared signature model validation for hardware-in-the-loop simulations

    Sanders, Jeffrey S.; Peters, Trina S.

    1997-07-01

    Techniques and tools for validation of real-time infrared target signature models are presented. The model validation techniques presented in this paper were developed for hardware-in-the-loop (HWIL) simulations at the U.S. Army Missile Command's Research, Development, and Engineering Center. Real-time target model validation is a required deliverable to the customer of a HWIL simulation facility and is a critical part of ensuring the fidelity of a HWIL simulation. There are two levels of real-time target model validation. The first level is comparison of the target model to some baseline or measured data which answers the question `are the simulation inputs correct?'. The second level of validation is a simulation validation which answers the question `for a given target model input is the simulation hardware and software generating the correct output?'. This paper deals primarily with the first level of target model validation. IR target signature models have often been validated by subjective visual inspection or by objective, but limited, statistical comparisons. Subjective methods can be very satisfying to the simulation developer but offer little comfort to the simulation customer since subjective methods cannot be documented. Generic statistical methods offer a level of documentation, yet are often not robust enough to fully test the fidelity of an IR signature. Advances in infrared seeker and sensor technology have led to the necessity of system specific target model validation. For any HWIL simulation it must be demonstrated that the sensor responds to the real-time signature model in a manner which is functionally equivalent to the sensor's response to a baseline model. Depending on the application, a baseline method can be measured IR imagery or the output of a validated IR signature prediction code. Tools are described that generate validation data for HWIL simulations at MICOM and example real-time model validations are presented.

  2. Valuing hope.

    McMillan, John; Walker, Simon; Hope, Tony

    2014-01-01

    This article argues that hope is of value in clinical ethics and that it can be important for clinicians to be sensitive to both the risks of false hope and the importance of retaining hope. However, this sensitivity requires an understanding of the complexity of hope and how it bears on different aspects of a well-functioning doctor-patient relationship. We discuss hopefulness and distinguish it, from three different kinds of hope, or 'hopes for', and then relate these distinctions back to differing accounts of autonomy. This analysis matters because it shows how an overly narrow view of the ethical obligations of a clinician to their patient, and autonomy, might lead to scenarios where patients regret the choices they make.

    We performed 24- and 48-h MIC determinations of posaconazole and voriconazole against more than 16,000 clinical isolates of Candida species. By using the 24- and 48-h epidemiological cutoff values (ECVs), the categorical agreement between the 24-h and reference 48-h broth microdilution results ranged from 97.1% (C. parapsilosis and voriconazole) to 99.8% (C. krusei and voriconazole), with 0.0 to 2.9% very major discrepancies (VMD). The essential agreement (within 2 log2 dilutions) between the 24- and 48-h results was 99.6% for both posaconazole and voriconazole. The MIC results obtained for both posaconazole and voriconazole after only 24 h of incubation may be used to determine the susceptibilities of Candida spp. to these important antifungal agents. The applications of ECVs to this large collection of Candida isolates suggests the potential to develop 24-h species-specific clinical breakpoints for both posaconazole and voriconazole.

MÉTODOS: Realizou-se espirometria forçada, de acordo com as normas da Sociedade Brasileira de Pneumologia e Tisiologia, em 643 adultos brancos não-fumantes. Os valores previstos obtidos por pesquisadores brasileiros em 1992 e os obtidos por quatro grupos de pesquisadores estrangeiros foram comparados com os novos valores previstos brasileiros obtidos em 2006. Em uma segunda fase, os valores médios obtidos em 65 mulheres e 79 homens adultos foram comparados aos valores previstos obtidos pelas diversas equações de referência. RESULTADOS: O teste t para amostras pareadas revelou diferenças significativas entre os valores previstos obtidos pelas seis equações e os obtidos pela equação brasileira de 2006. Na segunda fase, observou-se que os valores previstos obtidos por Crapo et al. e os obtidos por Hankinson et al. para os méxico-americanos mostraram valores médios semelhantes aos observados na nova amostra. Porém, quando os valores previstos obtidos na nova amostra foram comparados com os obtidos por esses autores, discrepâncias foram observadas, com valores previstos altos e baixos. Os valores obtidos pela equação brasileira de 2006 mostraram as menores diferenças em comparação com os valores médios obtidos na nova amostra. CONCLUSÕES: Estes resultados sublinham a importância de se usar equações de predição para espirometria que sejam apropriadas para nossa população.OBJECTIVE: To compare the most recent (2006 predicted values of forced vital capacity and forced expiratory volume in one second for spirometry in Brazilians with those obtained using other reference equations and to validate the findings

  7. Valuing vaccination

    2014-01-01

    Vaccination has led to remarkable health gains over the last century. However, large coverage gaps remain, which will require significant financial resources and political will to address. In recent years, a compelling line of inquiry has established the economic benefits of health, at both the individual and aggregate levels. Most existing economic evaluations of particular health interventions fail to account for this new research, leading to potentially sizable undervaluation of those interventions. In line with this new research, we set forth a framework for conceptualizing the full benefits of vaccination, including avoided medical care costs, outcome-related productivity gains, behavior-related productivity gains, community health externalities, community economic externalities, and the value of risk reduction and pure health gains. We also review literature highlighting the magnitude of these sources of benefit for different vaccinations. Finally, we outline the steps that need to be taken to implement a broad-approach economic evaluation and discuss the implications of this work for research, policy, and resource allocation for vaccine development and delivery.

    网络交易中日益增长的欺诈行为阻碍了人们参与网上交易的积极性,激励参与方在网络交易中保持诚信交易是非常必要的。而目前电子商务网站中使用的在线信誉反馈系统难以实现激励卖方一直保持诚信交易。基于此,构建了基于交易时间价值的信誉反馈集结模型。理论模型表明:在生存期无限的情形下,只要历史交易信息对目前信誉度的影响足够小,卖方会保持持续的诚信交易。同时通过模拟分析比较了生存期有限的卖方在不同的历史信誉评价权重下的策略,卖方在不同的超额收益下的策略。分析表明:卖方从欺诈交易中获得的超额利润越大,卖方越不会保持诚信交易;基于交易时间价值的信誉反馈集结模型能够激励卖方保持持续的诚信交易行为。%Fraud has been on rise recently and it prevents people from participating in online auction markets, actuating the auctioneers to trade honestly is very important. Since the simple reputation model of the reputation feedback systems cannot promote honest trade sustainedly, this paper proposes the reputation model based on time value. The theoretical analysis shows that: in an unlimited survival circumstances, the auctioneers will maintain honest trade as long as the impact of the history transaction information is small enough to true current reputation. At the same time, through simulation analysis, we compared the linfited survival auctioneers' strategy under different weight of the historical reputation evaluation and different above quota cheating income. The result shows that: the more profit the auctioneers earn from cheating, the auctioneers will not maintain the integrity transaction; the model based on time value will encourage the auctioneers to maintain honestly in the future transactions.

    This thesis is concerned with ``Automatic Validation of Numerical Solutions''. The basic theory of interval analysis and self-validating methods is introduced. The mean value enclosure is applied to discrete mappings for obtaining narrow enclosures of the iterates when applying these mappings...... is the possiblility to combine the three methods in an extremely flexible way. We examine some applications where this flexibility is very useful. A method for Taylor expanding solutions of ordinary differential equations is presented, and a method for obtaining interval enclosures of the truncation errors incurred...... with intervals as initial values. A modification of the mean value enclosure of discrete mappings is considered, namely the extended mean value enclosure which in most cases leads to even better enclosures. These methods have previously been described in connection with discretizing solutions of ordinary...

    Evidence for the factorial, convergent and discriminant, and criterion-related validity of the Metacomprehension Scale (MCS) was examined in a sample of 237 young adults. The instrument was factorially heterogeneous but exhibited homogeneity within each of the seven subscales. Evidence for the convergent and discriminant validity of the MCS was examined by correlating the subscales from the MCS with subscales from metacognitive questionnaires measuring similar constructs from related domains. In general, correlations within constructs were larger than correlations between constructs, providing preliminary evidence of the convergent and discriminant validity of the MCS. The criterion-related validity of the MCS relative to other metacognitive measures was examined by using the metacognitive measures and the MCS to predict comprehension performance. The MCS predicted performance better than the other measures of metacognition and accounted for variance in performance not accounted for by the other measures. These results show promise for the value of self-assessments of metacomprehension. Copyright 1997Academic Press

    As a unique way to resolve the disputes, the court mediation which has the authority and the mobility bears the internal tension of the legality and validity in the meantime. The court system emphasizes the two values respectively through the“solving problem with case closed”and“mediating according to the law”, but the pursuit to the validity still occupies the leading position. In practice, this pursuit faces the double difficulties on the self digestion of validity and the lack of legality, while it is also hard that the mediation by law becomes the foundation of effective mediation due to its fuzzy connotation and the deficient reasons. Two modes,“legality by validity”and“validity based on legality”, do not completely fit China’s reality. As a result, it’s necessary to seek another way of new balance between the legality and validity under the background of social transformation.%作为一种独特的纠纷解决方式,法院调解在具备了权威性和灵活性的同时,也承受着合法性与有效性的内在张力。我国法院在调解中分别通过“案结事了”和“依法调解”的要求对这两种价值加以强调,但是对有效性的追求占据了主导地位。在实践中,这种选择面临着有效性的自我消解和合法性不足的双重困难,而依法调解又由于自身内涵模糊和依据不足而难以成为有效调解的基础。“通过有效性累积合法性”和“基于合法性获得有效性”两种模式都不能完全契合中国的现实与理想,必须在转型社会背景下寻求两者间新的平衡之道。

    2009-07-31

    ADAM research identifies and appraises existing and new policy options that can contribute to different combinations of adaptation and mitigation strategies. These options address the demands a changing climate will place on protecting citizens and valuable ecosystems - i.e., adaptation - as well as addressing the necessity to restrain/control humankind's perturbation to global climate to a desirable level - i.e., mitigation. The work package Mitigation 1 (Ml) has the core objective to simulate mitigation options and their related costs for Europe until 2050 and 2100 respectively. The focus of this deliverable is on the period 2005 to 2050. The long-term period until 2100 is covered in the previous deliverable D2, applying the POLES model for this time horizon. The analysis constitutes basically a techno-economic analysis. Depending on the sector analyzed it is either directly combined with a policy analysis (e.g. in the transport sector, renewables sector) or the policy analysis is performed qualitatively as a subsequent and independent step after the techno-economic analysis is completed (e.g. in the residential and service sectors). The book includes the following chapters: scenarios and macroeconomic assumptions; methodological issues analyzing mitigation options; the integrated global energy model POLES and its projections for the reference and 2 deg C scenarios; forest and basic materials sector; residential sector in Europe; the service (tertiary) and the primary sectors in Europe; basic products and other manufacturing industry sectors; transport sectors in Europe; renewable sector in Europe; conversion sector in Europe; syntheses and sectoral analysis in Europe; macroeconomic impacts of climate policy in the EU; the effects of the financial crisis on baseline simulations with implications for climate policy modeling: an analysis using the global model E3MG 2008-2012; conclusions and policy recommendations.

    The Excavator Design Validation tool verifies excavator designs by automatically generating control systems and modeling their performance in an accurate simulation of their expected environment. Part of this software design includes interfacing with human operations that can be included in simulation-based studies and validation. This is essential for assessing productivity, versatility, and reliability. This software combines automatic control system generation from CAD (computer-aided design) models, rapid validation of complex mechanism designs, and detailed models of the environment including soil, dust, temperature, remote supervision, and communication latency to create a system of high value. Unique algorithms have been created for controlling and simulating complex robotic mechanisms automatically from just a CAD description. These algorithms are implemented as a commercial cross-platform C++ software toolkit that is configurable using the Extensible Markup Language (XML). The algorithms work with virtually any mobile robotic mechanisms using module descriptions that adhere to the XML standard. In addition, high-fidelity, real-time physics-based simulation algorithms have also been developed that include models of internal forces and the forces produced when a mechanism interacts with the outside world. This capability is combined with an innovative organization for simulation algorithms, new regolith simulation methods, and a unique control and study architecture to make powerful tools with the potential to transform the way NASA verifies and compares excavator designs. Energid's Actin software has been leveraged for this design validation. The architecture includes parametric and Monte Carlo studies tailored for validation of excavator designs and their control by remote human operators. It also includes the ability to interface with third-party software and human-input devices. Two types of simulation models have been adapted: high-fidelity discrete

    The Earth System Grid Federation (ESGF) Peer-to-Peer (P2P) is a software infrastructure for the management, dissemination, and analysis of model output and observational data. The ESGF grid is composed with several types of nodes which have different roles. About 40 data nodes host model outputs and datasets using thredds catalogs. About 25 compute nodes offer remote visualization and analysis tools. About 15 index nodes crawl data nodes catalogs and implement faceted and federated search in a web interface. About 15 Identity providers nodes manage accounts, authentication and authorization. Here we will present an actual size test federation spread across different institutes in different countries and a python test suite that were started in December 2013. The first objective of the test suite is to provide a simple tool that helps to test and validate a single data node and its closest index, compute and identity provider peer. The next objective will be to run this test suite on every data node of the federation and therefore test and validate every single node of the whole federation. The suite already implements nosetests, requests, myproxy-logon, subprocess, selenium and fabric python libraries in order to test both web front ends, back ends and security services. The goal of this project is to improve the quality of deliverable in a small developers team context. Developers are widely spread around the world working collaboratively and without hierarchy. This kind of working organization context en-lighted the need of a federated integration test and validation process.

    2012-10-01

    We propose a refined theory of basic individual values intended to provide greater heuristic and explanatory power than the original theory of 10 values (Schwartz, 1992). The refined theory more accurately expresses the central assumption of the original theory that research has largely ignored: Values form a circular motivational continuum. The theory defines and orders 19 values on the continuum based on their compatible and conflicting motivations, expression of self-protection versus growth, and personal versus social focus. We assess the theory with a new instrument in 15 samples from 10 countries (N = 6,059). Confirmatory factor and multidimensional scaling analyses support discrimination of the 19 values, confirming the refined theory. Multidimensional scaling analyses largely support the predicted motivational order of the values. Analyses of predictive validity demonstrate that the refined values theory provides greater and more precise insight into the value underpinnings of beliefs. Each value correlates uniquely with external variables.

  19. Jack knifing for semivariogram validation

    2010-01-01

    Full Text Available The semivariogram function fitting is the most important aspect of geostatistics and because of this the model chosen must be validated. Jack knifing may be one the most efficient ways for this validation purpose. The objective of this study was to show the use of the jack knifing technique to validate geostatistical hypothesis and semivariogram models. For that purpose, topographical heights data obtained from six distinct field scales and sampling densities were analyzed. Because the topographical data showed very strong trend for all fields as it was verified by the absence of a sill in the experimental semivariograms, the trend was removed with a trend surface fitted by minimum square deviation. Semivariogram models were fitted with different techniques and the results of the jack knifing with them were compared. The jack knifing parameters analyzed were the intercept, slope and correlation coefficient between measured and estimated values, and the mean and variance of the errors calculated by the difference between measured and estimated values, divided by the square root of the estimation variances. The ideal numbers of neighbors used in each estimation was also studied using the jack knifing procedure. The jack knifing results were useful in the judgment of the adequate models fitted independent of the scale and sampling densities. It was concluded that the manual fitted semivariogram models produced better jack knifing parameters because the user has the freedom to choose a better fit in distinct regions of the semivariogram.

    1990-03-01

    Opinion is divided on the clinical usefulness of the postcoital (Sims-Huhner) test in diagnosing infertility. To evaluate the validity of this test, we reviewed the world's literature in English and calculated four indexes of validity for each study with sufficient information. The sensitivity of the test ranged from 0.09 to 0.71, specificity from 0.62 to 1.00, predictive value of abnormal from 0.56 to 1.00, and predictive value of normal from 0.25 to 0.75. In addition to the problem of poor validity, the test suffers from a lack of standard methodology, lack of a uniform definition of normal, and unknown reproducibility. The postcoital test lacks validity as a test for infertility.

    This report describes the status of the Busted Butte Unsaturated Zone Transport Test (UZTT) and documents the progress of construction activities and site and laboratory characterization activities undertaken in fiscal year 1998. Also presented are predictive flow-and-transport simulations for Test Phases 1 and 2 of testing and the preliminary results and status of these test phases. Future anticipated results obtained from unsaturated-zone (UZ) transport testing in the Calico Hills Formation at Busted Butte are also discussed in view of their importance to performance assessment (PA) needs to build confidence in and reduce the uncertainty of site-scale flow-and-transport models and their abstractions for performance for license application. The principal objectives of the test are to address uncertainties associated with flow and transport in the UZ site-process models for Yucca Mountain, as identified by the PA working group in February 1997. These include but are not restricted to: (1) The effect of heterogeneities on flow and transport in unsaturated and partially saturated conditions in the Calico Hills Formation. In particular, the test aims to address issues relevant to fracture-matrix interactions and permeability contrast boundaries; (2) The migration behavior of colloids in fractured and unfractured Calico Hills rocks; (3) The validation through field testing of laboratory sorption experiments in unsaturated Calico Hills rocks; (4) The evaluation of the 3-D site-scale flow-and-transport process model (i.e., equivalent-continuum/dual-permeability/discrete-fracture-fault representations of flow and transport) used in the PA abstractions for license application; and (5) The effect of scaling from lab scale to field scale and site scale.

    1999-08-01

    The literature on natural resource scarcity indicators is reviewed. Scarcity indicators can be classified by what is being measured: value of the resource stock or value of extracted resource commodities; whose value is considered: social vs. private scarcity; and by the mode of valuation considered: exchange value and use value. Prices and rents are common measures of exchange value or indicators of ''exchange scarcity'' and unit costs can be seen as use value indicators or indicators of {sup u}se scarcity{sup .} The major aim of this paper is to demonstrate the links between productivity indicators such as unit costs and the classical concept of use value. The two classes of indicator relate to John Commons' discussions of scarcity and efficiency, and a marginal vs. a non-marginal approach to value and scarcity. The classical use value concept also has wider relevance for issues of valuation in energy, resource, and environmental policy. (author)

  3. Indigenous environmental values as human values

    2016-12-01

    Full Text Available The claim that in natural resource management (NRM a change from anthropocentric values and ethics to eco-centric ones is necessary to achieve sustainability leads to the search for eco-centric models of relationship with the environment. Indigenous cultures can provide such models; hence, there is the need for multicultural societies to further include their values in NRM. In this article, we investigate the environmental values placed on a freshwater environment of the Wet Tropics by a community of indigenous Australians. We discuss their environmental values as human values, and so as beliefs that guide communities’ understanding of how the natural world should be viewed and treated by humans. This perspective represents a step forward in our understanding of indigenous environmental values, and a way to overcome the paradigm of indigenous values as valued biophysical attributes of the environment or processes happening in landscapes. Our results show that the participant community holds biospheric values. Restoring these values in the NRM of the Wet Tropics could contribute to sustainability and environmental justice in the area.

    Generally accepted standards for testing and validating ecosystem models would benefit both modellers and model users. Universally applicable test procedures are difficult to prescribe, given the diversity of modelling approaches and the many uses for models. However, the generally accepted scientific principles of documentation and disclosure provide a useful framework for devising general standards for model evaluation. Adequately documenting model tests requires explicit performance criteria, and explicit benchmarks against which model performance is compared. A model's validity, reliability, and accuracy can be most meaningfully judged by explicit comparison against the available alternatives. In contrast, current practice is often characterized by vague, subjective claims that model predictions show 'acceptable' agreement with data; such claims provide little basis for choosing among alternative models. Strict model tests (those that invalid models are unlikely to pass) are the only ones capable of convincing rational skeptics that a model is probably valid. However, 'false positive' rates as low as 10% can substantially erode the power of validation tests, making them insufficiently strict to convince rational skeptics. Validation tests are often undermined by excessive parameter calibration and overuse of ad hoc model features. Tests are often also divorced from the conditions under which a model will be used, particularly when it is designed to forecast beyond the range of historical experience. In such situations, data from laboratory and field manipulation experiments can provide particularly effective tests, because one can create experimental conditions quite different from historical data, and because experimental data can provide a more precisely defined 'target' for the model to hit. We present a simple demonstration showing that the two most common methods for comparing model predictions to environmental time series (plotting model time series

    Holloway, Michael Andrew [Los Alamos National Laboratory

    2015-03-04

    We have conducted an experiment to explore an alternative non-contact method of measuring the Inconel target window temperature. This experiment involves using a standard color camera to observe the visible light emitted from the Inconel target window at high heat in order to estimate the window temperature. The safety limit to prevent target window failure is 700 °C and therefore we need a reliable and accurate method of measuring temperature especially in the range of 600 °C to 700 °C if it is to replace the IR camera. In this temperature range the window will emit a significant amount of black body radiation within the visible range and hence the idea of using a color camera. The goal is to see if the shift in window color (determined by the RBG pixel values of the camera) as the target window is heated to 700 °C can be calibrated to the temperature.The reasons for exploring this as an alternative to an IR are camera are: significant cost reduction and potentially less complicated to calibrate.

    Full Text Available El propósito de este artículo es revisar la validez explicativa de la teoría marxista del valor a la luz de los cambios que se producen en el capitalismo tras la crisis de los años '70, cuando progresivamente se instaura (sobre todo en los países centrales un régimen de acumulación y regulación -que muchos autores han denominado "posfordismo"- con diferencias importantes respecto al dominante desde la posguerra. La tesis central que se defiende es que gran parte de las tendencias ancladas en las transformaciones operadas en el sistema de producción de núcleos hegemónicos del capital internacional -desde la terciarización a los nuevos modos de gestión y formación de la fuerza de trabajo- ponen en cuestión el concepto de "trabajo abstracto" que estaba en la base de la teoría del valor en su formulación clásica por Marx, tornando necesaria la revisión crítica de esta teoría.The purpose of this article is to go through the explanatory validity of the marxist theory of value in the light of the changes that are produced in the capitalism after the crisis of 70's, when a regime of accumulation an regulation - that many authors have named "post-fordism" - is progressively established (especially in central countries with important differences regarding the dominant since the post-war period. The main thesis defended is that a great part of the trends anchored in the transformations operated on the system of production of hegemonic cores of the international capital - since the service economy to the new manners of management and training of the labour forces - put in question the concept of "abstract labour" that was in the base of the theory of value in its classic formulation by Marx, making necessary the critical review of this theory.

    针对裂缝性致密油藏,基于拉普拉斯变换及Stehfest数值反演,建立了一种可用于直井体积改造产能评价的半解析两区复合模型,模型内区包含有限条无限导流水力裂缝,外区是经典的Warren-Root双重介质系统。并分析了导压系数比α、裂缝传导率比β、储容比ω、窜流系数λ以及改造半径reD等参数敏感性,绘制了产量递减图版。结果表明:从产量递减曲线,可以看出体积改造直井产能遵循“L”形递减规律;导压系数比越大,初期产量越高;裂缝传导率比对整个生产周期的产能都有影响,裂缝传导率比越大,单井产量越高,同时还会伴有明显的复合边界流特征;储容比和窜流系数分别影响双重介质基质-裂缝系统窜流发生的程度和时间;内区人工主裂缝条数越多或改造渗透率越大,复合边界流越明显,产能也越高,这说明改造程度与改造体积对产能的增加都很重要,应注意两者的合理优化。矿场实例验证了该模型在裂缝性封闭边界油藏直井多次压裂改造以及裂缝性致密油藏直井体积改造方面的适用性和实用性。%In this study,based on Laplace transformation and Stehfest numerical algorithm,a vertical well frac-ture network reconstruction semi-analytical deliverability evaluation model which can be used for fractured tight oil reservoirs was established.The proposed model is a composite system with two concentric regions.The inner region contains finite number of hydraulic fractures and the flow in each fracture is assumed linear.The outer region is modeled with the classical Warren-Root model and radial flow takes place in this region.The influ-ences of related parameters,such as diffusivity coefficient ratio,fracture conductivity ratio,storativity ratio, cross-flow factor and so forth,on the seepage flow were analyzed by using the established model.The results show that the

    This paper introduces a bibliometric, citation network-based method for assessing the social validation of novel research, and applies this method to the development of high-throughput toxicology research at the US Environmental Protection Agency. Social validation refers to the acceptance of novel research methods by a relevant scientific community; it is formally independent of the technical validation of methods, and is frequently studied in history, philosophy, and social studies of science using qualitative methods. The quantitative methods introduced here find that high-throughput toxicology methods are spread throughout a large and well-connected research community, which suggests high social validation. Further assessment of social validation involving mixed qualitative and quantitative methods are discussed in the conclusion. PMID:28005974

    /or knowledge (i.e. a better understanding of public 'perception') grounds. Although relying on a wide array of philosophical backgrounds, their aim is usually to capture values through the creation of small public spaces where citizens can discuss the issues with each other, scientists and decision makers. As a consequence, a number of concepts are used in literature such as participative, deliberative and discursive democracy. Following Habermas's seminal work, the term 'deliberative democracy' is sometimes used as an umbrella concept for a rich and diverse set of approaches in recent and contemporary thinking about democracy. Deliberation is seen as a form of discourse, theoretically and ideologically requiring ideal conditions of equality of access and justification of arguments. Deliberation involves reasoned debate between citizens. It draws on a notion of procedural legitimacy. That is, if the conditions for deliberation are fulfilled, then the outcomes are supposed to be the best possible. Nevertheless, many subtle conceptual differences remain between theorists of deliberative democracy; analysing these is the first aim of this work package. The RISCOM model adds to this essentially free and unconstrained communication in the 'deliberative arena' the communications going on in a 'transparency arena'. These are oriented more towards the practical requirements of decision making in the political system. In the transparency arena there is a function of 'stretching' that makes it possible for stakeholders to evaluate claims of truth, legitimacy and authenticity. The primary focus is not to reach consensus on all matters at hand but rather to increase awareness among both the decision makers and the more general public about all perspectives. Participation is therefore also required but for another purpose than in the 'deliberative arena'. Participation is mobilized for stretching and for transforming the

    The primary objective for the Model Validation Status Review was to perform a one-time evaluation of model validation associated with the analysis/model reports (AMRs) containing model input to total-system performance assessment (TSPA) for the Yucca Mountain site recommendation (SR). This review was performed in response to Corrective Action Request BSC-01-C-01 (Clark 2001, Krisha 2001) pursuant to Quality Assurance review findings of an adverse trend in model validation deficiency. The review findings in this report provide the following information which defines the extent of model validation deficiency and the corrective action needed: (1) AMRs that contain or support models are identified, and conversely, for each model the supporting documentation is identified. (2) The use for each model is determined based on whether the output is used directly for TSPA-SR, or for screening (exclusion) of features, events, and processes (FEPs), and the nature of the model output. (3) Two approaches are used to evaluate the extent to which the validation for each model is compliant with AP-3.10Q (Analyses and Models). The approaches differ in regard to whether model validation is achieved within individual AMRs as originally intended, or whether model validation could be readily achieved by incorporating information from other sources. (4) Recommendations are presented for changes to the AMRs, and additional model development activities or data collection, that will remedy model validation review findings, in support of licensing activities. The Model Validation Status Review emphasized those AMRs that support TSPA-SR (CRWMS M&O 2000bl and 2000bm). A series of workshops and teleconferences was held to discuss and integrate the review findings. The review encompassed 125 AMRs (Table 1) plus certain other supporting documents and data needed to assess model validity. The AMRs were grouped in 21 model areas representing the modeling of processes affecting the natural and

    Full Text Available The objective was to validate the content of an instrument on nasogastric intubation skills based on Pasquali's model of content validation. This was a methodological study conducted with 23 nursing teachers in public higher education institutions in Rio Grande do Norte. The Content Validation Index (CVI and Kappa Index was applied. In the overall evaluation, the instrument obtained a CVI with values above 0.75 with a total CVI of 0.95 and a total Kappa of 0.91. However, some changes were made on the instructional sequence requirements of the topics, and to vocabulary. The instrument proved to be reliable and trustworthy in facilitating nursing care quality and can be used for health services and educational institutions to assess skill levels of professionals and undergraduate students. However, the instrument requires additional stages for a more precise and specific content validation.

    2016-04-01

    Full Text Available This essay was motivated by the gap between proclaimed democratic principles and the perceptions of politics which are exhibited by the citizens in transitional countries -more specifically in the Republic of Macedonia. It is based on research data collected in the past few decades, which illustrate that, in their political actions, the citizens are highly motivated by personal benefits and profits, rather than by their internalized values and ideologies. Non-democratic, authoritarian values prevail, while politics is perceived as a value itself, in the most materialistic meaning of the word. It creates a suitable milieu for growth of corruption, nepotism and clientelism. The authors conclude that such a circulus vitsiosus is a corner stone of the Macedonian political regime, and an enormous obstacle for the advancement of the participative, democratic political culture in reality, in spite of its formal acceptance.

  17. On Validating Boolean Optimizers

    CERN Document Server

    Morgado, Antonio

    2011-01-01

    Boolean optimization finds a wide range of application domains, that motivated a number of different organizations of Boolean optimizers since the mid 90s. Some of the most successful approaches are based on iterative calls to an NP oracle, using either linear search, binary search or the identification of unsatisfiable sub-formulas. The increasing use of Boolean optimizers in practical settings raises the question of confidence in computed results. For example, the issue of confidence is paramount in safety critical settings. One way of increasing the confidence of the results computed by Boolean optimizers is to develop techniques for validating the results. Recent work studied the validation of Boolean optimizers based on branch-and-bound search. This paper complements existing work, and develops methods for validating Boolean optimizers that are based on iterative calls to an NP oracle. This entails implementing solutions for validating both satisfiable and unsatisfiable answers from the NP oracle. The wo...

    Full Text Available This article provides a discussion on the question of validity in qualitative evaluation. Although validity in qualitative inquiry has been widely reflected upon in the methodological literature (and is still often subject of debate, the link with evaluation research is underexplored. Elaborating on epistemological and theoretical conceptualizations by Guba and Lincoln and Creswell and Miller, the article explores aspects of validity of qualitative research with the explicit objective of connecting them with aspects of evaluation in social policy. It argues that different purposes of qualitative evaluations can be linked with different scientific paradigms and perspectives, thus transcending unproductive paradigmatic divisions as well as providing a flexible yet rigorous validity framework for researchers and reviewers of qualitative evaluations.

    Validation is one of the software engineering disciplines that help build quality into software. The major objective of software validation process is to determine that the software performs its intended functions correctly and provide information about its quality and reliability. This paper identifies general measures for the specific goals and its specific practices of Validation Process Area (PA) in Capability Maturity Model Integration (CMMI). CMMI is developed by Software Engineering Institute (SEI). CMMI is a framework for improvement and assessment of a software development process. CMMI needs a measurement program that is practical. The method we used to define the measures is to apply the Goal Question Metrics (GQM) paradigm to the specific goals and its specific practices of Validation Process Area in CMMI.

  2. Verification and validation benchmarks.

    Energy Technology Data Exchange (ETDEWEB)

    Oberkampf, William Louis; Trucano, Timothy Guy

    2007-02-01

    Verification and validation (V&V) are the primary means to assess the accuracy and reliability of computational simulations. V&V methods and procedures have fundamentally improved the credibility of simulations in several high-consequence fields, such as nuclear reactor safety, underground nuclear waste storage, and nuclear weapon safety. Although the terminology is not uniform across engineering disciplines, code verification deals with assessing the reliability of the software coding, and solution verification deals with assessing the numerical accuracy of the solution to a computational model. Validation addresses the physics modeling accuracy of a computational simulation by comparing the computational results with experimental data. Code verification benchmarks and validation benchmarks have been constructed for a number of years in every field of computational simulation. However, no comprehensive guidelines have been proposed for the construction and use of V&V benchmarks. For example, the field of nuclear reactor safety has not focused on code verification benchmarks, but it has placed great emphasis on developing validation benchmarks. Many of these validation benchmarks are closely related to the operations of actual reactors at near-safety-critical conditions, as opposed to being more fundamental-physics benchmarks. This paper presents recommendations for the effective design and use of code verification benchmarks based on manufactured solutions, classical analytical solutions, and highly accurate numerical solutions. In addition, this paper presents recommendations for the design and use of validation benchmarks, highlighting the careful design of building-block experiments, the estimation of experimental measurement uncertainty for both inputs and outputs to the code, validation metrics, and the role of model calibration in validation. It is argued that the understanding of predictive capability of a computational model is built on the level of

  3. Validation suite for MCNP

    Energy Technology Data Exchange (ETDEWEB)

    Mosteller, R. D. (Russell D.)

    2002-01-01

    Two validation suites, one for criticality and another for radiation shielding, have been defined and tested for the MCNP Monte Carlo code. All of the cases in the validation suites are based on experiments so that calculated and measured results can be compared in a meaningful way. The cases in the validation suites are described, and results from those cases are discussed. For several years, the distribution package for the MCNP Monte Carlo code1 has included an installation test suite to verify that MCNP has been installed correctly. However, the cases in that suite have been constructed primarily to test options within the code and to execute quickly. Consequently, they do not produce well-converged answers, and many of them are physically unrealistic. To remedy these deficiencies, sets of validation suites are being defined and tested for specific types of applications. All of the cases in the validation suites are based on benchmark experiments. Consequently, the results from the measurements are reliable and quantifiable, and calculated results can be compared with them in a meaningful way. Currently, validation suites exist for criticality and radiation-shielding applications.

    Viviana Fernandez

    2003-03-01

    Full Text Available Value at Risk (VaR is a measure of the maximum potential change in value of a portfolio of financial assets with a given probability over a given time horizon. VaR became a key measure of market risk since the Basle Committee stated that banks should be able to cover losses on their trading portfolios over a ten-day horizon, 99 percent of the time. A common practice is to compute VaR by assuming that changes in value of the portfolio are normally distributed, conditional on past in-formation. However, assets returns usually come from fat-tailed distri-butions. Therefore, computing VaR under the assumption of conditional normality can be an important source of error. We illustrate this point with Chilean and U.S. returns series by resorting to extreme value theory (EVT and GARCH-type models. In addition, we show that dynamic estimation of empirical quantiles can also give more accurate VaR estimates than quantiles of a standard normal.

    The GHG Functions and Extensions to be added to the NASA Electronic Library System (NELS) 1.1 product are described. These functions will implement the 'output request' capability within the Object Browser. The functions will be implemented in two parts. The first part is a code to be added to the Object Browser (X version) to implement menus allowing the user to request that objects be copied to specific media, or that objects be downloaded to the user's system following a specific protocol, or that the object be printed to one of the printers attached to the host system. The second part is shell scripts which support the various menu selections. Additional scripts to support functions within the GHG shell (X version) will also be created along with the X version of the GHG Shell as initial capability for the 27 Mar. prototype. The scripts will be composed of C shell routines that will accept parameters (primary file pathways). Certain limitations in functionality will invoke Mail instead of Oracle Mail since that has yet to be delivered and the NELS invocation will default to the X-Windows version instead of the ASCII version.

    Oriental medicine, since its origin in China, has had a long history extending over 2000 years. Today, it comprises several types of medicine predominately practiced in East Asia, including traditional Chinese, traditional Korean, and Kampo medicine. The distinctive medical system of traditional Korean medicine was established shortly after the publication of Donguibogam by Dr. Heo Jun in 1613. Donguibogam is highly acclaimed across East Asia; in 2009, in light of its historical medical value, the United Nations Educational, Scientific, and Cultural Organization registered the book on its cultural heritage list. Here, we review the historical medical value of Donguibogam. The findings confirm that Donguibogam developed a unique and independent form of traditional Korean medicine and innovatively reformed the disease classification system. Moreover, Donguibogam emphasized the importance of disease prevention and medical pragmatism. This book also accelerated the development of folk medicine. Owing to its historical medical value, Donguibogam is now considered the 'bible' of Oriental medicine. Its wide acceptance has contributed to the expansion of Korean medicine utilization among the general public. Donguibogam has also played an important role in the establishment of traditional Korean medicine as a universally valid and original form of medicine, independent of traditional Chinese medicine.

    This paper introduces an innovative statistical approach towards understanding how variation impacts the acceptance criteria of quality attributes. Because of more complex stage-wise acceptance criteria, traditional process capability measures are inadequate for general application in the pharmaceutical industry. The probability of acceptance concept provides a clear measure, derived from specific acceptance criteria for each quality attribute. In line with the 2011 FDA Guidance, this approach systematically evaluates data and scientifically establishes evidence that a process is capable of consistently delivering quality product. The probability of acceptance provides a direct and readily understandable indication of product risk. As with traditional capability indices, the acceptance probability approach assumes that underlying data distributions are normal. The computational solutions for dosage uniformity and dissolution acceptance criteria are readily applicable. For dosage uniformity, the expected AV range may be determined using the s lo and s hi values along with the worst case estimates of the mean. This approach permits a risk-based assessment of future batch performance of the critical quality attributes. The concept is also readily applicable to sterile/non sterile liquid dose products. Quality attributes such as deliverable volume and assay per spray have stage-wise acceptance that can be converted into an acceptance probability. Accepted statistical guidelines indicate processes with C pk > 1.33 as performing well within statistical control and those with C pk  1.33 is associated with a centered process that will statistically produce less than 63 defective units per million. This is equivalent to an acceptance probability of >99.99%.

  19. Feasibility of voxel-based Dose Painting for recurrent Glioblastoma guided by ADC values of Diffusion-Weighted MR imaging.

    2016-12-01

    Glioblastoma Multiforme (GBM) is the most common malignant brain tumor and frequently recurs in the same location after radiotherapy. Intensive treatment targeting localized lesion is required to improve GBM outcome, but dose escalation using conventional methods is limited by healthy tissue tolerance. Helical Tomotherapy (HT) Dose Painting (DP) treatments were simulated to safely deliver high doses in the recurrent regions. Apparent Diffusion Coefficient (ADC) data from five recurrent GBM were retrospectively considered for planning. Hypo-fractionated (25-50Gy, 5 fractions) voxel-based prescriptions were opportunely converted to personalized structured-based dose maps to create DP plans with a commercial Treatment Planning System. Optimized plans were generated and analyzed in terms of plan conformity to dose prescription (Q0.90-1.10), tolerance of the healthy tissues (DMAX), and dosimetry accuracy of the deliverable plans (γ-index). Only three of the five cases could receive a safe retreatment without violating the maximum critical organs dose constraints. The conformity of the simulated plans was between 40.9% and 79.9% (Q0.90-1.10), their delivery time was in the range of 38.3-63.6min, while the dosimetry showed γ-index of 82.4-92.4%. This study proved the ability of our method to simulate personalized, deliverable and dosimetrically accurate DPBN plans. HT hypo-fractionated treatments guided by ADC maps can be realized and applied to deliver high doses in the GBM recurrent regions, although there are some critical issues related to low Q0.90-1.10 values, to exceeding of healthy-tissue dose constraints for some patients and long delivery times.

  4. Software Validation via Model Animation

    Dutle, Aaron M.; Munoz, Cesar A.; Narkawicz, Anthony J.; Butler, Ricky W.

    2015-01-01

    This paper explores a new approach to validating software implementations that have been produced from formally-verified algorithms. Although visual inspection gives some confidence that the implementations faithfully reflect the formal models, it does not provide complete assurance that the software is correct. The proposed approach, which is based on animation of formal specifications, compares the outputs computed by the software implementations on a given suite of input values to the outputs computed by the formal models on the same inputs, and determines if they are equal up to a given tolerance. The approach is illustrated on a prototype air traffic management system that computes simple kinematic trajectories for aircraft. Proofs for the mathematical models of the system's algorithms are carried out in the Prototype Verification System (PVS). The animation tool PVSio is used to evaluate the formal models on a set of randomly generated test cases. Output values computed by PVSio are compared against output values computed by the actual software. This comparison improves the assurance that the translation from formal models to code is faithful and that, for example, floating point errors do not greatly affect correctness and safety properties.

Five main types of problems were used for validation: small criticality benchmark problems; full-core reactor benchmarks for light water reactors; fixed-source coupled neutron-photon dosimetry benchmarks; depletion/burnup benchmarks; and full-core reactor performance benchmarks. We compared Shift results to measured data and other simulated Monte Carlo radiation transport code results, and found very good agreement in a variety of comparison measures. These include prediction of critical eigenvalue, radial and axial pin power distributions, rod worth, leakage spectra, and nuclide inventories over a burn cycle. Based on this validation of Shift, we are confident in Shift to provide reference results for CASL benchmarking.

    2015-01-01

    Political homogeneity within a scientific field nurtures threats to the validity of many research conclusions by allowing ideologically compatible values to influence interpretations, by minimizing skepticism, and by creating premature consensus. Although validity threats can crop in any research, the usual corrective activities in science are more likely to be minimized and delayed.

    Full Text Available In this paper, I respond to the challenge raised against contemporary experimental neurobiology according to which the field is in a state of crisis because of the multiple experimental protocols employed in different laboratories and strengthening their reliability that presumably preclude the validity of neurobiological knowledge. I provide an alternative account of experimentation in neurobiology which makes sense of its experimental practices. I argue that maintaining a multiplicity of experimental protocols and strengthening their reliability are well justified and they foster rather than preclude the validity of neurobiological knowledge. Thus, their presence indicates thriving rather than crisis of experimental neurobiology.

    Full Text Available Changes in today's business environment require companies to orient to strategic marketing. The company accepting strategic marketing has a proactive approach and focus on continuous review and reappraisal of existing and seeking new strategic business areas. Difficulties in achieving target profit and growth require turning marketing from the dominant viewpoint of the tangible product to creating superior value and developing relationships with customers. Value orientation implies gaining competitive advantage through continuous research and understanding of what value represents to the consumers and discovering new ways to meet their required values. Strategic marketing investment requires that the investment in the creation of values should be regularly reviewed in order to ensure a focus on customers with high profit potential and environmental value. This increases customer satisfaction and retention and long-term return on investment of companies.

  19. The problem with value

    Science.gov (United States)

    O’Doherty, John P.

    2015-01-01

    Neural correlates of value have been extensively reported in a diverse set of brain regions. However, in many cases it is difficult to determine whether a particular neural response pattern corresponds to a value-signal per se as opposed to an array of alternative non-value related processes, such as outcome-identity coding, informational coding, encoding of autonomic and skeletomotor consequences, alongside previously described “salience” or “attentional” effects. Here, I review a number of experimental manipulations that can be used to test for value, and I identify the challenges in ascertaining whether a particular neural response is or is not a value signal. Finally, I emphasize that some non-value related signals may be especially informative as a means of providing insight into the nature of the decision-making related computations that are being implemented in a particular brain region.

  2. Globalization and Values

    OpenAIRE

    John WHALLEY

    2005-01-01

    This paper discusses a central element in globalization debate little addressed by economists, namely the interactions at global, national, and community levels between globalization and societally based values. Social values refer to wider notions of collective identity: religious values, attitudes towards materialism, moral beliefs, and a sense of collective awareness and are a broader and more encompassing concept than social capital discussed in recent economics and sociology literature. ...

    Impact of chosen behavioural factors on imprecision of present value is discussed here. The formal model of behavioural present value is offered as a result of this discussion. Behavioural present value is described here by fuzzy set. These considerations were illustrated by means of extensive numerical case study. Finally there are shown that in proposed model the return rate is given, as a fuzzy probabilistic set.

  4. Emerging sacred values

    Directory of Open Access Journals (Sweden)

    Sonya Sachdeva

    2009-12-01

    Full Text Available Sacred values are different from secular values in that they are often associated with violations of the cost-benefit logic of rational choice models. Previous work on sacred values has been largely limited to religious or territorial conflicts deeply embedded in historical contexts. In this work we find that the Iranian nuclear program, a relatively recent development, is treated as sacred by some Iranians, leading to a greater disapproval of deals which involve monetary incentives to end the program. Our results suggest that depending on the prevalence of such values, incentive-focused negotiations may backfire.

  5. Business Value Game

    Marchenko, Artem; Duarte, Vasco

    Agile teams want to deliver maximum business value. That’s easy if the on-site Ccstomer assigns business value to each story. But how does the customer do that? How can you estimate business value? This workshop is run as a game, where teams have to make tough business decisions for their ”organizations”. Teams have to decide which orders to take and what to deliver first in order to earn more. The session gives the participants basic business value estimation techniques, but the main point is to make people live through the business situation and to help them feel the consequences of various choices.

    Tore, C.; Rodriguez Rivada, A.

    2014-07-01

    Estimation of the burn-up value of irradiated fuel and its isotopic composition are important for criticality analysis, spent fuel management and source term estimation. The practical way to estimate the irradiated fuel composition and burn.up value is calculation with validated code and nuclear data. Such validation of the neutronic codes and nuclear data requires the benchmarking with measured values. (Author)

    Current practice of validating predicted protein structural model is knowledge-based where scoring parameters are derived from already known structures to obtain decision on validation out of this structure information. For example, the scoring parameter, Ramachandran Score gives percentage conformity with steric-property higher value of which implies higher acceptability. On the other hand, Force-Field Energy Score gives conformity with energy-wise stability higher value of which implies low...

  8. A greenhouse-gas information system monitoring and validating emissions reporting and mitigation

    Energy Technology Data Exchange (ETDEWEB)

    Jonietz, Karl K [Los Alamos National Laboratory; Dimotakis, Paul E [JPL/CAL TECH; Roman, Douglas A [LLNL; Walker, Bruce C [SNL

    2011-09-26

    Current GHG-mitigating regimes, whether internationally agreed or self-imposed, rely on the aggregation of self-reported data, with limited checks for consistency and accuracy, for monitoring. As nations commit to more stringent GHG emissions-mitigation actions and as economic rewards or penalties are attached to emission levels, self-reported data will require independent confirmation that they are accurate and reliable, if they are to provide the basis for critical choices and actions that may be required. Supporting emissions-mitigation efforts and agreements, as well as monitoring energy- and fossil-fuel intensive national and global activities would be best achieved by a process of: (1) monitoring of emissions and emission-mitigation actions, based, in part, on, (2) (self-) reporting of pertinent bottom-up inventory data, (3) verification that reported data derive from and are consistent with agreed-upon processes and procedures, and (4) validation that reported emissions and emissions-mitigation action data are correct, based on independent measurements (top-down) derived from a suite of sensors in space, air, land, and, possibly, sea, used to deduce and attribute anthropogenic emissions. These data would be assessed and used to deduce and attribute measured GHG concentrations to anthropogenic emissions, attributed geographically and, to the extent possible, by economic sector. The validation element is needed to provide independent assurance that emissions are in accord with reported values, and should be considered as an important addition to the accepted MRV process, leading to a MRV&V process. This study and report focus on attributes of a greenhouse-gas information system (GHGIS) needed to support MRV&V needs. These needs set the function of such a system apart from scientific/research monitoring of GHGs and carbon-cycle systems, and include (not exclusively): the need for a GHGIS that is operational, as required for decision-support; the need for a

  20. VALUES AND VALORIZATION

    Directory of Open Access Journals (Sweden)

    2015-07-01

    Full Text Available I live with the feeling that, in the past few years, Romania has been a drifting ship. We do not know where is it going, nor the place it will arrive at. Like any individual endowed with reason, I wonder why chaos took over this society and, if I would have the power to change anything, what would be the solution to less troubled waters. I think we lost our way because we forgot to always refer to the values that should guide us ... or because we refer too often to non-values. I think we could find our way and stop wandering if we will rely our evolution on values, if we will teach our children from a young age what values and non-values are and if we could run our existence in the spirit of a real value horizon. People live together, not just coexist, as so deeply professor Gheorghe Mihai highlighted1. Coexistence is specific to herds, packs, hordes; but human community means collaboration, cooperation, consensualisation, which implies a consciousness towards values. "What is missing now to the human society is a behavior that relates to a code of virtue"2. Moral values are the support for the legal values. Unfortunately, today, it seems to me that values are inverted and that the belief in the perfectibility of the individual (and therefore the perfectibility of law is increasingly being questioned. Contemporary society is characterized by lack of motivation, lack of a strategy and the absence of any ideals. In this context, I believe that the individual today feels the necessity of some value referrences more acutely, whilst the society needs a law deeply based on moral values. As morality itself contributes to the valorization of the law, I think that moral appeal is more necessary today than yesterday, as a remedy for the individual and, consequently, the law to overcome their crisis. For all these reasons and also because I share the view that "the concrete law is not viable without values and these values are always expressed in the

  1. Values in dialogic pedagogy

    Directory of Open Access Journals (Sweden)

    Eugene Matusov

    2015-02-01

    Full Text Available In November 2014 on the Dialogic Pedagogy Journal Facebook page, there was an interesting discussion of the issue of values in dialogic pedagogy[1]. The main issue can be characterized as the following. Should dialogic pedagogy teach values? Should it avoid teaching values? Is there some kind of a third approach? The participants of the Facebook discussions were focusing on teaching values in dialogic pedagogy and not about teaching aboutvalues. On the one hand, it seems to be impossible to avoid teaching values. However, on the other hand, shaping students in some preset molding is apparently non-dialogic and uncritical (Matusov, 2009. In the former case, successful teaching is defined by how well and deeply the students accept and commit to the taught values. In the latter case, successful dialogic teaching may be defined by students’ critical examination of their own values against alternative values in a critical dialogue. Below, Eugene Matusov and Jay Lemke, active participants of this Facebook dialogue, provide their reflection on this important issue and encourage readers to join their reflective dialogue.[1] See in a public Facebook domain: https://www.facebook.com/DialogicPedagogyJournal/posts/894734337204533, https://www.facebook.com/DialogicPedagogyJournal/posts/896916850319615

    The following paper presents a practical approach to the validation process of coordinate measuring methods at an accredited laboratory, using a statistical model of metrological compatibility. The statistical analysis of measurement results obtained using a highly accurate system was intended to determine the permissible validation threshold values. The threshold value constitutes the primary criterion for the acceptance or rejection of the validated method, and depends on both the differences between measurement results with corresponding uncertainties and the individual correlation coefficient. The article specifies and explains the types of measuring methods that were subject to validation and defines the criterion value governing their acceptance or rejection in the validation process.

  3. Strange Weak Values

    CERN Document Server

    Hosoya, Akio

    2010-01-01

    We develop a formal theory of the weak values with emphasis on the consistency conditions and a probabilistic interpretation in the counter-factual processes. We present the condition for the choice of the post-selected state to give a negative weak value of a given projection operator and strange values of an observable in general. The general framework is applied to Hardy's paradox and the spin $1/2$ system to explicitly address the issues of counter-factuality and strange weak values. The counter-factual arguments which characterize the paradox specifies the pre-selected state and a complete set of the post-selected states clarifies how the strange weak values emerge.

  4. Many-valued logics

    CERN Document Server

    Bolc, Leonard

    1992-01-01

    Many-valued logics were developed as an attempt to handle philosophical doubts about the "law of excluded middle" in classical logic. The first many-valued formal systems were developed by J. Lukasiewicz in Poland and E.Post in the U.S.A. in the 1920s, and since then the field has expanded dramatically as the applicability of the systems to other philosophical and semantic problems was recognized. Intuitionisticlogic, for example, arose from deep problems in the foundations of mathematics. Fuzzy logics, approximation logics, and probability logics all address questions that classical logic alone cannot answer. All these interpretations of many-valued calculi motivate specific formal systems thatallow detailed mathematical treatment. In this volume, the authors are concerned with finite-valued logics, and especially with three-valued logical calculi. Matrix constructions, axiomatizations of propositional and predicate calculi, syntax, semantic structures, and methodology are discussed. Separate chapters deal w...

  5. Quantitative model validation techniques: new insights

    CERN Document Server

    Ling, You

    2012-01-01

    This paper develops new insights into quantitative methods for the validation of computational model prediction. Four types of methods are investigated, namely classical and Bayesian hypothesis testing, a reliability-based method, and an area metric-based method. Traditional Bayesian hypothesis testing is extended based on interval hypotheses on distribution parameters and equality hypotheses on probability distributions, in order to validate models with deterministic/stochastic output for given inputs. Two types of validation experiments are considered - fully characterized (all the model/experimental inputs are measured and reported as point values) and partially characterized (some of the model/experimental inputs are not measured or are reported as intervals). Bayesian hypothesis testing can minimize the risk in model selection by properly choosing the model acceptance threshold, and its results can be used in model averaging to avoid Type I/II errors. It is shown that Bayesian interval hypothesis testing...

    1997-07-01

    The FACTAR code models the thermal and mechanical behaviour of a CANDU fuel channel under degraded cooling conditions. FACTAR is currently undergoing a process of validation against various data sets in order to qualify its use in nuclear safety analysis. This paper outlines the methodology being followed in this effort. The BTF-104 and BTF-105A tests, conducted at Chalk River Laboratories, have been chosen as the first in reactor tests to be used for FACTAR validation. The BTF experiments were designed to represent CANDU fuel behaviour under typical large LOCA conditions. The two tests are summarized briefly, and the results of code comparisons to experimental data are outlined. The comparisons demonstrate that FACTAR is able to accurately predict the values of selected key parameters. As anticipated in the validation plan, further work is required to fully quantify simulation biases for all parameters of interest. (author)

  7. Orthorexia nervosa: validation of a diagnosis questionnaire.

    Donini, L M; Marsili, D; Graziani, M P; Imbriale, M; Cannella, C

    2005-06-01

    To validate a questionnaire for the diagnosis of orhorexia oervosa, an eating disorder defined as "maniacal obsession for healthy food". 525 subjects were enrolled. Then they were randomized into two samples (sample of 404 subjects for the construction of the test for the diagnosis of orthorexia ORTO-15; sample of 121 subjects for the validation of the test). The ORTO-15 questionnaire, validated for the diagnosis of orthorexia, is made-up of 15 multiple-choice items. The test we proposed for the diagnosis of orthorexia (ORTO 15) showed a good predictive capability at a threshold value of 40 (efficacy 73.8%, sensitivity 55.6% and specificity 75.8%) also on verification with a control sample. However, it has a limit in identifying the obsessive disorder. For this reason we maintain that further investigation is necessary and that new questions useful for the evaluation of the obsessive-compulsive behavior should be added to the ORTO-15 questionnaire.

    2002-12-06

    This paper represents a summary of our methodology for Verification and Validation and Uncertainty Quantification. A graded scale methodology is presented and related to other concepts in the literature. We describe the critical nature of quantified Verification and Validation with Uncertainty Quantification at specified Confidence levels in evaluating system certification status. Only after Verification and Validation has contributed to Uncertainty Quantification at specified confidence can rational tradeoffs of various scenarios be made. Verification and Validation methods for various scenarios and issues are applied in assessments of Quantified Reliability at Confidence and we summarize briefly how this can lead to a Value Engineering methodology for investment strategy.

  9. Cultural Values and Alexithymia

    Directory of Open Access Journals (Sweden)

    Chris Lo

    2014-10-01

    Full Text Available Alexithymia refers to difficulty with reflecting on and articulating emotional states. Previous research has found that Asian groups may tend toward greater alexithymia and that cultural values may mediate this difference, although the content of Asian values that form these pathways is unclear. This study examined the relationship between Confucian values, ethnicity, and alexithymia. A sample of 216 undergraduate students completed the Chinese Value Survey and the Toronto Alexithymia Scale. Asian Canadians scored more highly on alexithymia than non-Asian Canadians. Individuals who valued trustworthiness, patience, and kindness were found to be less alexithymic. The ability to be a source of kindness and security to others may be tied to the development of reflective awareness. Individuals who valued purity from desire and respect for social order were found to be more alexithymic. Such individuals may tend not to reflect on impure or socially disruptive thoughts and feelings. Values associated with purity and order mediated the difference between Asians and non-Asians on alexithymia. Asian Canadians may therefore score more highly on alexithymia because they prefer not to reflect on emotions associated with impurity or social disorder.

    Mendl, Christian B

    2013-01-01

    We develop a numerical framework for the quantum analogue of the "classical" lattice Boltzmann method (LBM), with the Maxwell-Boltzmann distribution replaced by the Fermi-Dirac function. To accommodate the spin density matrix, the distribution functions become 2x2-matrix valued. We show that the efficient, commonly used BGK approximation of the collision operator is valid in the present setting. The framework could leverage the principles of LBM for simulating complex spin systems, with applications to spintronics.

    Self-Validating Thermocouple (SVT) Systems capable of detecting sensor probe open circuits, short circuits, and unnoticeable faults such as a probe debonding and probe degradation are useful in the measurement of temperatures. SVT Systems provide such capabilities by incorporating a heating or excitation element into the measuring junction of the thermocouple. By heating the measuring junction and observing the decay time for the detected DC voltage signal, it is possible to indicate whether the thermocouple is bonded or debonded. A change in the thermal transfer function of the thermocouple system causes a change in the rise and decay times of the thermocouple output. Incorporation of the excitation element does not interfere with normal thermocouple operation, thus further allowing traditional validation procedures as well.

    Lee, Sang-Gun; Min, Jae H.

    In this paper, we validate MEDIQUAL constructs through the different media users in help desk service. In previous research, only two end-users' constructs were used: assurance and responsiveness. In this paper, we extend MEDIQUAL constructs to include reliability, empathy, assurance, tangibles, and responsiveness, which are based on the SERVQUAL theory. The results suggest that: 1) five MEDIQUAL constructs are validated through the factor analysis. That is, importance of the constructs have relatively high correlations between measures of the same construct using different methods and low correlations between measures of the constructs that are expected to differ; and 2) five MEDIQUAL constructs are statistically significant on media users' satisfaction in help desk service by regression analysis.

    2017-02-01

    The Center for NDE (CNDE) at Iowa State University has a long history of developing physics models for NDE and packaging these models into simulation tools which make the modeling capabilities accessible to CNDEs industrial sponsors. Recent work at CNDE has led to the development of a new ultrasonic simulation package, UTSim2, which aims to continue this tradition of supporting industrial application of CNDE models. In order to meet this goal, UTSim2 has been designed as an extensible software package which can support previously-developed physics models as well as future models yet to be developed. Initial work has focused on the implementation of a Gauss-Hermite beam model, a paraxial approximation, which is implemented as part of the Thompson-Gray measurement model. This paper will present recent validation results and include comparisons against both previously-validated model output and newly-performed experiments.

    2012-01-01

    This paper addresses the problem of learning a finite linear combination of operator-valued kernels. We study this problem in the case of kernel ridge regression for functional responses with a lr-norm constraint on the combination coefficients. We propose a multiple operator-valued kernel learning algorithm based on solving a system of linear operator equations by using a block coordinate descent procedure. We experimentally validate our approach on a functional regression task in the context of finger movement prediction in Brain-Computer Interface (BCI).

  5. Values in psychotherapy.

    Science.gov (United States)

    Holmes, J

    1996-01-01

    There is a tension between those who hold that psychotherapy is a scientific discipline and therefore "value-free," and those who believe that values are inherent in the nature of psychotherapy. Psychoanalysis has moved from a science-based ideology, through the ethical concerns of Melanie Klein, to a recognition of the "aesthetic" dimension--the creation of suitable forms that can contain psychological distress. From this latter perspective, the antagonism between religion and psychotherapy, initiated by Freud, becomes less acute. Action-based ethical systems, which ignore the inner world, are critically scrutinized. The evidence suggesting there is a relationship between good outcome in psychotherapy and shared values between therapist and client is reviewed. It is posited that through examination of the "ethical countertransference," therapists should become aware of their own value systems and how they influence practice.

    Full Text Available This paper reports the results of a questionnaire for assessing social values in university students (VASOL. Increasingly, society demands that its professionals must know how to cope with complexity, considering the human and social aspects of such situations. The European Higher Education Area (ehea has emphasized the interest in training future professionals as agents of social change, not only as regards the creation and management of new knowledge but also in the action of citizens who contribute to greater social cohesion. This research team has developed a new questionnaire to assess social justice and solidarity values. The questionnaire revealed a unifactorial configuration coherent with the theory. A sample of 945 university students completed the VASOL and these were subjected to a series of instruments aimed at evaluating the validity of the questionnaire. The VASOL proved to be a reliable and valid instrument. We discuss the usefulness of this new instrument for the screening of social justice and solidarity values, specifically for their detection, and for assessing social or interpersonal skills in the current model of the ehea and validation of psycho-educational programs.

    2013-01-01

    Full Text Available The present article deals with value orientations and their role in men’s lives, particularly, in young people’s lives. This notion was introduced by the American theoretical sociologist T. Parsons, one of the creators of modern theoretical sociology. The scientist made an attempt to construct the structural and analytical theory of social action, combining personal interests (needs and aims and situation, it takes place in. The issue of value orientations remains acute for psychology. Herein we have considered several most important works, relating to the considered issue. Age aspects of young people’s value orientations are of peculiar interest to us. When analyzing this phenomenon, one should take into consideration the psychological formations, inhere for a certain age. In fact every age has its unique structure, which may change when passing from one development stage to another. Basing on this fact, we’ve considered the values, depending on the age features of the youth, relying upon the works of the scientists, working with different categories of the youth, such as: teenagers, students, children of different nationalities. It is not surprising that most scientists have come to the conclusion that the chief role in value orientation belongs to a family, originates in relations with parents and teachers. The positive reinforcement to the future develops throughout life in accordance with a lifestyle of a family, society and political situation in a state.Life orientations as a type of value orientations show different types of young people’s preferences. Value structure of its consciousness has its own specific character, depending on the age peculiarities. The dynamics of the transition from one age to another is accompanied with the reappraisal of values, eventually, influencing the life strategy of the future generation

    2007-01-01

    In this book, we consider various many-valued logics: standard, linear, hyperbolic, parabolic, non-Archimedean, p-adic, interval, neutrosophic, etc. We survey also results which show the tree different proof-theoretic frameworks for many-valued logics, e.g. frameworks of the following deductive calculi: Hilbert's style, sequent, and hypersequent. We present a general way that allows to construct systematically analytic calculi for a large family of non-Archimedean many-valued logics: hyperrational-valued, hyperreal-valued, and p-adic valued logics characterized by a special format of semantics with an appropriate rejection of Archimedes' axiom. These logics are built as different extensions of standard many-valued logics (namely, Lukasiewicz's, Goedel's, Product, and Post's logics). The informal sense of Archimedes' axiom is that anything can be measured by a ruler. Also logical multiple-validity without Archimedes' axiom consists in that the set of truth values is infinite and it is not well-founded and well...

  13. Value of Fundamental Science

    Science.gov (United States)

    Burov, Alexey

    Fundamental science is a hard, long-term human adventure that has required high devotion and social support, especially significant in our epoch of Mega-science. The measure of this devotion and this support expresses the real value of the fundamental science in public opinion. Why does fundamental science have value? What determines its strength and what endangers it? The dominant answer is that the value of science arises out of curiosity and is supported by the technological progress. Is this really a good, astute answer? When trying to attract public support, we talk about the ``mystery of the universe''. Why do these words sound so attractive? What is implied by and what is incompatible with them? More than two centuries ago, Immanuel Kant asserted an inseparable entanglement between ethics and metaphysics. Thus, we may ask: which metaphysics supports the value of scientific cognition, and which does not? Should we continue to neglect the dependence of value of pure science on metaphysics? If not, how can this issue be addressed in the public outreach? Is the public alienated by one or another message coming from the face of science? What does it mean to be politically correct in this sort of discussion?

  14. Getting Value from Research

    Science.gov (United States)

    Duke, Charles

    2004-03-01

    During the past decade the environment for and execution of industrial research has changed profoundly, as recently documented in Robert Buderi, Engines of Tomorrow (Simon and Shuster, New York, 2000). The vertically integrated single-firm research-through-product value chains of the twentieth century are gone, replaced by value chains the various elements of which can come from different firms in different parts of the world as described, e.g., by Henry W. Cheesbrough, Open Innovation (Harvard Business School Press, Boston, 2003). The consequences of this change are profound for national R policy, the R strategies of specific firms, and individual researchers. (See e.g., C. B. Duke, How to get value from R, Physics World, 17 (August 1997), 17.) In this presentation I sketch the strategies that firms employ to generate value from their research. Then I discuss the ingredients that are required to implement these strategies by creating value chains to deliver the fruits of research to customers. I indicate how the role of physical sciences is changing as unique hardware, based on advanced research in the physical sciences, becomes an increasingly minor (and often outsourced) component of integrated systems offerings. I close by noting implications of these developments on the nature of the careers that physicists can expect in industry and on the skills and cultural attributes that are required to be successful in the new industrial research environment.

    2001-01-01

    For more than 30 years, the author has studied the model-theoretic aspects of the theory of valued fields and multi-valued fields. Many of the key results included in this book were obtained by the author whilst preparing the manuscript. Thus the unique overview of the theory, as developed in the book, has been previously unavailable. The book deals with the theory of valued fields and mutli-valued fields. The theory of Prüfer rings is discussed from the `geometric' point of view. The author shows that by introducing the Zariski topology on families of valuation rings, it is possible to distinguish two important subfamilies of Prüfer rings that correspond to Boolean and near Boolean families of valuation rings. Also, algebraic and model-theoretic properties of multi-valued fields with near Boolean families of valuation rings satisfying the local-global principle are studied. It is important that this principle is elementary, i.e., it can be expressed in the language of predicate calculus. The most important...

    Organizations that follow the principles of good Earned Value Management (EVM) create an environment that allows teams to successfully operate and thrive ? even in the face of challenges that could negatively impact their projects. Earned Value Project Management (EVPM) is a methodology used to measure and communicate the real physical progress of a project taking into account the work completed, the time taken and the costs incurred to complete that work. As a result, EVPM allows more educated and effective management decision-making, which helps evaluate and control project risk by measuring project progress in monetary terms. In the first two editions of Earned Value Project Management, Quentin W. Fleming and Joel M. Koppelman provided guidance for project management practitioners already familiar with EVPM, was well as those who were new to the use of this technique. The third edition expanded the information available on of EVPM for medium and smaller projects while still being relevant for larger projec...

    The objective of this paper was to advance towards finding sustainable solutions to deal with biogas digestate and contribute to faster development of the market for digestate treatment products. The study compares digestate treatment costs through four different treatment plants, estimates the potential fertilizing and humus value (PFHV) of the derived products and allocates the cash flows to show the possible regional benefits. The treatment costs for the pre-dried solid fraction of digestate ranged from €19 to €23/tonne output. These costs may be covered by vending treatment products at a price reaching at least 34-41% of their PFHV (ca €55/tonne). Treatment of raw digestate generates high operating costs (€216-247/tonne output), much higher than the PFHV of the products (ca €35-51/tonne). For such systems either the treatment has to be financially subsidized by the authorities or €13-32/tonne input should be covered by the substrate deliverers as a disposal fee. Nevertheless, a well-prepared investment concept in this field may allow the local binding of up to 80% of total cash flows. Finally, the current difficult market situation of the treatment products can be primarily improved by clearing their legal status at European level.

  3. Recursive Palindromic Smarandache Values

    In [1] Recursive Prime Numbers were studied and shown to be finite. This article deals with the same "recursive" topic, but applies the method to numbers whose Smarandache value, S(n), gives a palindromic number. Here, S(n) denotes the Smarandache function of least m such that n divides m!, and a palindrome is an integer that reads the same forwards and backwards (23432, for example). This sequence of recursive palindromic Smarandache values is shown to be finite...

    Do Americans have any morals? That’s a good question.Many people insist that ideas about right and wrong are merely personal opinions.Some voices,though,are calling Americans back to traditional moral values.William J.Bennett,former U.S.Secretary of Education,edited The Book of Virtues in 1993 to do just that.Bennett suggests that great moral stories can build character.The success of Bennett's book shows that many Americans still believe in moral values.But what are they?

    This paper investigates the relationship between the normality and the shared values for a meromorphic function on the unit disc △.Based on Marty's normality criterion and through a detailed analysis of the meromorphic functions,it is shown that if for every f∈F,f and f(k) share a and b on △ and the zeros of f(z)-a are of multiplicity k≥3,then F is normal on △,where F is a family of meromorphic functions on the unit disc △,and a and b are distinct values.

    The validation of modern software systems incorporates both functional and quality requirements. This paper proposes a validation approach for software quality requirement - its power consumption. This approach validates whether the software produces the desired results with a minimum expenditure of energy. We present energy requirements and an approach for their validation using a power consumption model, test-case specification, software traces, and power measurements. Three different appro...

    Full Text Available The complexity of business environment imposes the need for continuous change and reexamination of business marketing strategies of enterprises. Theory and practice of strategic management and marketing show that the activities of marketing, which are closely connected to corporate strategy, are the key drivers of growth. There is a positive correlation between competition intensity, marketing strategy and business performance of companies. Even though, managers of many companies don't see a clear connection between marketing strategy and business performance, numerous empirical research show that the companies which possess and efficiently use marketing resources and capabilities are more successful. In knowledge-based economics, the development of value oriented marketing strategies for all participants in the chain is a supposition of the survival, growth and development of companies. Competitive advantage is the essence of any strategy. Acquisition and maintenance of competitive advantage is more successful if the potentials for value creation are used efficiently. The paper examines the critical factors that influence alignment and transformation of marketing strategies in accordance with changes in value estimation. Superior value, is created in different network classes. Theory and practice researches create a reliable basis for the development of new concepts, marketing strategy business models that will contribute to competitive advantage of enterprises and the economy.
