    Full Text Available OBJECTIVE: This in situ study evaluated the discriminatory power and reliability of methods of dental plaque quantification and the relationship between visual indices (VI and fluorescence camera (FC to detect plaque. MATERIAL AND METHODS: Six volunteers used palatal appliances with six bovine enamel blocks presenting different stages of plaque accumulation. The presence of plaque with and without disclosing was assessed using VI. Images were obtained with FC and digital camera in both conditions. The area covered by plaque was assessed. Examinations were done by two independent examiners. Data were analyzed by Kruskal-Wallis and Kappa tests to compare different conditions of samples and to assess the inter-examiner reproducibility. RESULTS: Some methods presented adequate reproducibility. The Turesky index and the assessment of area covered by disclosed plaque in the FC images presented the highest discriminatory powers. CONCLUSION: The Turesky index and images with FC with disclosing present good reliability and discriminatory power in quantifying dental plaque.

    Objective: Using the standard genotype method, variable number of tandem repeats (VNTR), we constructed a VNTR database to cover all provinces and proposed a set of optimized VNTR loci combinations for each province, in order to improve the preventive and control programs on tuberculosis, in China. Methods: A total of 15 loci VNTR was used to analyze 4 116 Mycobacterium tuberculosis strains, isolated from national survey of Drug Resistant Tuberculosis, in 2007. Hunter-Gaston Index (HGI) was also used to analyze the discriminatory power of each VNTR site. A set combination of 12-VNTR, 10-VNTR, 8-VNTR and 5-VNTR was respectively constructed for each province, based on 1) epidemic characteristics of M. tuberculosis lineages in China, with high discriminatory power and genetic stability. Results: Through the completed 15 loci VNTR patterns of 3 966 strains under 96.36 % (3 966/4 116) coverage, we found seven high HGI loci (including QUB11b and MIRU26) as well as low stable loci (including QUB26, MIRU16, Mtub21 and QUB11b) in several areas. In all the 31 provinces, we found an optimization VNTR combination as 10-VNTR loci in Inner Mongolia, Chongqing and Heilongjiang, but with 8-VNTR combination shared in other provinces. Conclusions: It is necessary to not only use the VNTR database for tracing the source of infection and cluster of M. tuberculosis in the nation but also using the set of optimized VNTR combinations in monitoring those local epidemics and M. tuberculosis (genetics in local) population.

    Full Text Available The aims of this study were (i to compare women's water polo game-related statistics by match outcome (winning and losing teams and phase (preliminary, classificatory, and semi-final/bronze medal/gold medal, and (ii identify characteristics that discriminate performances for each phase. The game-related statistics of the 124 women's matches played in five International Championships (World and European Championships were analyzed. Differences between winning and losing teams in each phase were determined using the chi-squared. A discriminant analysis was then performed according to context in each of the three phases. It was found that the game-related statistics differentiate the winning from the losing teams in each phase of an international championship. The differentiating variables were both offensive (centre goals, power-play goals, counterattack goal, assists, offensive fouls, steals, blocked shots, and won sprints and defensive (goalkeeper-blocked shots, goalkeeper-blocked inferiority shots, and goalkeeper-blocked 5-m shots. The discriminant analysis showed the game-related statistics to discriminate performance in all phases: preliminary, classificatory, and final phases (92%, 90%, and 83%, respectively. Two variables were discriminatory by match outcome (winning or losing teams in all three phases: goals and goalkeeper-blocked shots

    The use of parasites as biological tags to discriminate among marine fish stocks has become a widely accepted method in fisheries management. Here, we first link this approach to its unstated ecological foundation, the decay in the similarity of the species composition of assemblages as a function of increasing distance between them, a phenomenon almost universal in nature. We explain how distance decay of similarity can influence the use of parasites as biological tags. Then, we perform a meta-analysis of 61 uses of parasites as tags of marine fish populations in multivariate discriminant analyses, obtained from 29 articles. Our main finding is that across all studies, the observed overall probability of correct classification of fish based on parasite data was about 71%. This corresponds to a two-fold improvement over the rate of correct classification expected by chance alone, and the average effect size (Zr = 0·463) computed from the original values was also indicative of a medium-to-large effect. However, none of the moderator variables included in the meta-analysis had a significant effect on the proportion of correct classification; these moderators included the total number of fish sampled, the number of parasite species used in the discriminant analysis, the number of localities from which fish were sampled, the minimum and maximum distance between any pair of sampling localities, etc. Therefore, there are no clear-cut situations in which the use of parasites as tags is more useful than others. Finally, we provide recommendations for the future usage of parasites as tags for stock discrimination, to ensure that future applications of the method achieve statistical rigour and a high discriminatory power.

    DNA barcoding of United Arab Emirates (UAE) native plants is of high practical and scientific value as the plants adapt to very harsh environmental conditions that challenge their identification. Fifty-one plant species belonged to 22 families, 2 monocots, and 20 eudicots; a maximum number of species being legumes and grasses were collected. To authenticate the morphological identification of the wild plant taxa, rbcL and matK regions were used in the study. The primer universality and discriminatory power of rbcL is 100%, while it is 35% for matK locus for these plant species. The sequences were submitted to GenBank; accession numbers were obtained for all the rbcL sequences and for 6 of matK sequences. We suggest rbcL as a promising barcode locus for the tested group of 51 plants. In the present study, an inexpensive, simple method of identification of rare desert plant taxa through rbcL barcode is being reported.

    2003-01-01

    The objective of this study was to compare discriminatory power of two different measures-graphic positioning scale (GPS) versus traditional scale (TS)-in assessing respondent acceptability of three preference measures: visual analog scale (VAS), standard gamble (SG), and willingness to pay (WTP). Two face-to-face interviews were conducted at least 1 week apart in a convenience sample of women aged 22 to 50 years with no history of breast cancer or cancer requiring chemotherapy. Study participation required completion of two surveys: one evaluating health preferences for an acute condition (chemotherapy-induced nausea and vomiting) and one evaluating a chronic condition (breast cancer). Data were collected from March 2000 to June 2000 at Ohio State University. Respondents were randomized to either GPS or TS surveys. Data analysis was a two-step process. First, a four-way multivariate repeated-measures analysis of variance (MANOVA) was conducted to assess respondent acceptability of three-preference metrics-VAS, SG, and WTP-in health-care decision making. Each of the four dependent variables, difficulty, clarity, reasonableness, and comfort in use in decision making, was measured on 9-point Likert scale. Second, a mixed design univariate analysis of variance (ANOVA) was performed for each dependent variable to optimize MANOVA analysis. Univariate ANOVAs, 2 x (2 x 3), were composed of three independent variables: assessment (GPS/TS), condition (acute and chronic), and preferences (VAS, SG, WTP). Of 126 respondents, 119 were usable and complete. MANOVA results showed (P <.05) for two main effects, condition (F4,114 = 6.375) and preferences (F8,110 = 9.290), and two significant interactions, condition x assessment (F4,114 = 3.421) and condition x preferences (F8,110 = 2.087). GPS has higher discriminatory power than TS in assessing respondent attitudes toward health preference measures. Results showed that respondents had more difficulty and less comfort when making

    The purpose of this study was to evaluate the discriminatory power of two DNA-based technique and a protein-based technique for the typing of nosocomial isolates of Klebsiella pneumoniae. A second objective was to determine the antimicrobial susceptibility pattern and characterise the presence of genes encoding extended-spectrum beta-lactamases (ESBLs) and carbapenemases. Forty-six K. pneumoniae isolates from patients with bloodstream infections at a tertiary care hospital in India between December 2014 and December 2015 were studied. All isolates were typed using enterobacterial repetitive intergenic consensus sequence-polymerase chain reaction (ERIC-PCR), randomly amplified polymorphic DNA (RAPD) analysis and matrix-assisted laser desorption ionisation time-of-flight (MALDI-TOF) mass spectrometry. Antimicrobial susceptibility profiles and ESBLs were detected using the BD Phoenix system. The types of ESBL and carbapenemase genes present were detected using PCR. Isolates were subtyped into 31, 30 and 33 distinct genotypes by ERIC-PCR, RAPD and MALDI-TOF, respectively. Several isolates displaying identical DNA fingerprints were binned into different branches based on their proteomic fingerprint. Antimicrobial susceptibility tests revealed that 33/46 strains were multidrug resistant (MDR); a majority of the strains (83%) were sensitive to colistin. PCR-based analysis demonstrated 19 strains to harbour two or more ESBL and carbapenemase genes. ERIC-PCR was the most reproducible method for typing K. pneumoniae isolates and could not be substituted by MALDI-TOF for clonality analysis. A high degree of genetic diversity and the presence of MDR genes highlight the challenges in treating K. pneumoniae-associated infections.

    To determine the feasibility, concurrent validity and discriminatory power of the instrument for Identification of Parents At Risk for child Abuse and Neglect (IPARAN) among Dutch parents with a newborn child. Community paediatrics. Data from a controlled trial were used. In total, 2659 Dutch parents with a newborn child were invited to participate. Of the 2659 parents, 759 parents filled in the consent form and participated in the study. Concurrent validity was determined by calculating correlations-using the Pearson's correlation (r)-between the IPARAN score and related constructs from the following instruments: the Empowerment Questionnaire 2.0, the Family Functioning Questionnaire and the Parenting Stress Questionnaire. Discriminatory power was determined by calculating receiver operating characteristic (ROC) curves between high-risk mothers and low-risk mothers according to their scores on the related constructs. Feasibility was determined by examining the percentage of missing answers. In terms of concurrent validity, we found that 3 out of 12 correlations between the IPARAN score and related constructs were strong (ie, r>0.50) and 4 out of 12 were medium (ie, r=0.30-0.49). In terms of discriminatory power, mothers with a score in the borderline/clinical range or lowest 10 percent (P10) range of the related constructs (high-risk mothers) had a higher IPARAN score than mothers with a score in the normal range or highest 90 percent (P90) range of the related constructs (low-risk mothers). Effect sizes varied from d=0.37 to d=1.93, and the area under the ROC curve varied from 0.62 to 0.93. Regarding feasibility, the part of the IPARAN filled in by the mother had on average 0.7% missing answers, whereas the part of the IPARAN filled in by the father had on average 1.7% missing answers. The results of this study support the concurrent validity, discriminatory power and feasibility of the IPARAN among a population of Dutch parents with a newborn child.

    The purpose of our study was to evaluate the discriminatory power of MRI in high-field magnet (1.5 T) for differentiation of adrenal non-adenomas vs adenomas assessing the following parameters separately and in combination: mean diameter of adrenal mass; previously described and new ratios as well as index calculated from signal intensity (SI) on SE T2-weighted images, chemical shift imaging (CSI), and Gd-DTPA-enhanced dynamic studies. One hundred eight adrenal masses (36 non-hyperfunctioning adenomas, 27 pheochromocytomas, 23 aldosterone-secreting adenomas, 20 malignant masses and 2 cortisol-secreting adenomas) in 95 patients were evaluated with SE sequences, CSI and Gd-DTPA dynamic studies. Indices and ratios of SI for all examined MRI methods were calculated and examined retrospectively for significance of differences between the groups with calculation of sensitivity and specificity. Receiver operating characteristics (ROC) analysis of calculated parameters in combination was performed. The multifactorial analysis of all four parameters, including size of the tumor, T2{sub liver} index, CSI ratio reflecting lipid content in the tumor and Wo{sub max/last} ratio reflecting maximal washout of contrast agent from the tumor had 100 % sensitivity and 100 % specificity in characterization of adrenal non-adenoma. The best performance of combination of mean tumor diameter with single MRI SI parameter was achieved in combination with T2{sub liver} index for all adrenal masses (area under ROC 0.987) and CSI ratio for non-hyperfunctioning adrenal masses (area under ROC 0.991). Magnetic resonance imaging enables sensitive and specific diagnosis of adrenal non-adenoma. (orig.)

  14. The impact of mixing lithologies in clast shape measurements on its discriminatory power - a case study from a temperate Alpine glacier

    Clast shape measurements have become a standard tool in the reconstruction of transport histories in a variety of depositional settings (Demir et al., 2009). In glacial environments, the combined use of clast form and roundness has become an established tool in the past 15 years or so, and environments where this tool has been used range from temperate and polythermal to cold-based glaciers. In addition, the method has been transferred to palaeo-environments where the knowledge gained in aforementioned studies has taken the degree of accuracy in sedimentological investigations to a higher level (cf. Lukas et al., 2009, and references therein). All of these studies use the approach originally advocated by Benn and Ballantyne (1994), but perhaps the most notable difference is that some researchers mix different lithologies within their samples of 50 clasts. However, the role of lithology on clast shape in a glacial environment has never been systematically analysed, except for one pilot study (Bennett et al., 1997). Likewise, some previous studies have highlighted the problem of distinguishing between fluvial and subglacially-transported clasts using co-variance plots, and thus, more work is needed in both these respects. We here present a set of clast shape data gathered from the foreland and surrounding slopes of temperate Findelengletscher, Switzerland, to (a) test the versatility of clast shape in distinguishing of populations of clasts transported along different paths and (b) assess the role of lithology on the discriminatory potential of the method, most notably using co-variance plots. The main result of this pilot study is that the sampled lithology has a marked effect on clast shape results within the same control group. This is manifest in an overlap of envelopes in both RA- or RWR-C40-covariance plots. If kept separate, all three lithologies display separate control envelopes, in this case in RWR-C40-co-variance plots, thus keeping their discriminatory

    The purpose of this work is to investigate the discriminatory power of the Biopharmaceutics Classification System (BCS)-biowaiver in vitro methodology, i.e., to investigate if a BCS-biowaiver approach would have detected the Cmax differences observed between two zolpidem tablets and to identify the cause of the in vivo difference. Several dissolution conditions were tested with three zolpidem formulations: the reference (Stilnox), a bioequivalent formulation (BE), and a nonbioequivalent formulation (N-BE). Zolpidem is highly soluble at pH 1.2, 4.5, and 6.8. Its permeability in Caco-2 cells is higher than that of metoprolol and its transport mechanism is passive diffusion. None of the excipients (alone or in combination) showed any effect on permeability. All formulations dissolved more than 85% in 15 min in the paddle apparatus at 50 rpm in all dissolution media. However, at 30 rpm the nonbioequivalent formulation exhibited a slower dissolution rate. A slower gastric emptying rate was also observed in rats for the nonbioequivalent formulation. A slower disintegration and dissolution or a delay in gastric emptying might explain the Cmax infra-bioavailability for a highly permeable drug with short half-life. The BCS-biowaiver approach would have declared bioequivalence, although the in vivo study was not conclusive but detected a 14% mean difference in Cmax that precluded the bioequivalence demonstration. Nonetheless, these findings suggest that a slower dissolution rate is more discriminatory and that rotation speeds higher than 50 rpm should not be used in BCS-biowaivers, even if a coning effect occurs.

    value of TNM staging in survival prediction, but not the value of the IASLC/ATS/ERS classification. Further analysis suggested that only BRCA1 and ERBB3 in the signature were independent risk factors after adjusting for the IASLC/ATS/ERS classification by Cox regression. A new algorithm of the two-gene expression signature containing BRCA1 and ERBB3 was generated. Adding the two-gene signature into the IASLC/ATS/ERS classification model further improved the discriminatory c-statistic from 0.728 to 0.756. Conclusion: The two-gene signature composed of BRCA1 and ERBB3 was an independent risk factor of the IASLC/ATS/ERS classification, which can be used to improve the discriminatory power of prognosis prediction of the IASLC/ATS/ERS classification in early-stage lung adenocarcinoma. The two-gene signature combination with the IASLC/ATS/ERS classification might contribute to better patient stratification for adjuvant chemoradiotherapy or targeted therapy after the surgery.

    Using a social identity perspective, two experiments examined the effects of power and the legitimacy of power differentials on intergroup bias. In Experiment 1, 125 math-science students were led to believe that they had high or low representation in a university decision-making body relative to social-science students and that this power position was either legitimate or illegitimate. Power did not have an independent effect on bias; rather, members of both high and low power groups showed more bias when the power hierarchy was illegitimate than when it was legitimate. This effect was replicated in Experiment 2 (N = 105). In addition, Experiment 2 showed that groups located within an unfair power hierarchy expected the superordinate power body to be more discriminatory than did those who had legitimately high or low power. The results are discussed in terms of their implications for group relations. Copyright 2003 Society for Personality and Social Psychology, Inc.

    The power supply working group was assigned the problem of pulse charging the 3-MeV gun. The gun is a radial line structure that has two charging configurations: a single ring charged to 500 kV or nine rings charged from 100 to 200 kV. In either configuration, the pulsed source must rapidly charge the structure's ring(s) before breakdown can begin. The issues encountered in charging the structure can be divided into two categories. First, the charging system must be well matched to the gun structure. Proper impedance matching will avoid reflections and limit the fault current if the ring should spark. Second, several systems can achieve the wide range of charge voltages necessary. Some are better suited to high voltages, while others are better at low voltages. The following paragraphs will address the impedance matching issues are review three choices for pulse generators.

    The aims of this study were (a) to compare water polo game-related statistics by context (winning and losing teams) and phase (preliminary, classification, and semifinal/bronze medal/gold medal), and (b) identify characteristics that discriminate performances for each phase. The game-related statistics of the 230 men's matches played in World Championships (2007, 2009, and 2011) and European Championships (2008 and 2010) were analyzed. Differences between contexts (winning or losing teams) in each phase (preliminary, classification, and semifinal/bronze medal/gold medal) were determined using the chi-squared statistic, also calculating the effect sizes of the differences. A discriminant analysis was then performed after the sample-splitting method according to context (winning and losing teams) in each of the 3 phases. It was found that the game-related statistics differentiate the winning from the losing teams in each phase of an international championship. The differentiating variables are both offensive and defensive, including action shots, sprints, goalkeeper-blocked shots, and goalkeeper-blocked action shots. However, the number of discriminatory variables decreases as the phase becomes more demanding and the teams become more equally matched. The discriminant analysis showed the game-related statistics to discriminate performance in all phases (preliminary, classificatory, and semifinal/bronze medal/gold medal phase) with high percentages (91, 90, and 73%, respectively). Again, the model selected both defensive and offensive variables.

    Full Text Available This study analyzes discriminatory intentions shared by members of the German majority against several outgroups in Germany. Patterns of discriminatory intentions against various minority groups were investigated for several indicators, including gender, age, and political orientation, by means of a representative survey (N = 1,778. The relationship between prejudices and discriminatory intentions against different target groups was also analyzed. Prejudice and discriminatory intentions show moderate but consistently positive correlations in relation to one and the same target group. Moreover, it was found that discriminatory intentions against one outgroup are related to hostile attitudes towards other outgroups, too. The results support the hypothesis of a syndrome of group-focused enmity.

  6. Action group for nuclear power information

    Following the nuclear power controversy in the Swedish general election of 1976, a group of technical employees of ASEA-Atom formed an action group for nuclear power information. This was a spontaneous move in which management was not involved. The object was to provide a balance to uninformed campaigns by 'environmental' action groups. The level of political activity among technical personnel is low, but once the threshold has been crossed the desire for information by the public has been shown to be great. It has however been difficult to obtain a hearing in radio, TV or the national press. The local press has on the other hand proved open. While no significant effect among the public can be demonstrated, there seems to have been some influence on politicians. There has been contact with corresponding organisations in Denmark, Finland and the UK, and in the Federal Republic of Germany in July 1978 a European Energy Association was formed to balance such organisations as European Environmental Bureau.

    To compare the discriminatory power of pulsed-field gel electrophoresis (PFGE) and sequence-based typing (SBT) in Legionella outbreaks for determining the infection source. Twenty-five investigations of Legionnaires' disease were analyzed by PFGE, SBT and Dresden monoclonal antibody. The results suggested that monoclonal antibody could reduce the number of Legionella isolates to be characterized by molecular methods. The epidemiological concordance PFGE-SBT was 100%, while the molecular concordance was 64%. Adjusted Wallace index (AW) showed that PFGE has better discriminatory power than SBT (AWSBT→PFGE = 0.767; AWPFGE→SBT = 1). The discrepancies appeared mostly in sequence type (ST) 1, a worldwide distributed ST for which PFGE discriminated different profiles. SBT discriminatory power was not sufficient verifying the infection source, especially in worldwide distributed STs, which were classified into different PFGE patterns.

  12. Trade Facilitation Provisions in Regional Trade Agreements: Discriminatory or Non-discriminatory?

    2016-12-01

    Full Text Available The RTAs with trade facilitation provisions have been expected to generate a larger net trade-creating effect and complement the discriminatory feature of RTAs but have yet to be empirically proven. Recognizing the limitations of existing studies, we conducted a quantitative analysis on the effects of RTAs with and without trade facilitation provisions on both intra- and extra-bloc trade by using a modified gravity equation. We applied the Poisson Pseudo-Maximum Likelihood (PPML estimation with time varying exporter and importer fixed effect method to panel data consisting of 45,770 country pairs covering 170 countries for 2000-2010. We found that the trade facilitation provisions in existing RTAs are non-discriminatory by generating more intra- and extra-bloc trade in general. In particular, we found that the trade effects of RTAs in the APEC region are much stronger than the general case covering all RTAs in the world. In addition, as we control the trade effect of a country's trade facilitation, which is ranked by the World Bank's logistic performance index, RTAs consisting of trade facilitation provisions are discriminatory for trade in final goods and non-discriminatory for trade in intermediate goods. Overall, we endeavor to "explain," instead of "hypothesizing," why most of the recent RTAs contain trade facilitation provisions, especially in light of the deepening regional interdependence through trade in parts and components under global value chains and support the necessity of multilateralizing RTAs by implementing non-discriminatory trade facilitation provisions.

    Historically, a number of typing methods have been evaluated for Staphylococcus aureus strain characterization. The emergence of contemporary strains of community-associated S. aureus, and the ensuing epidemic with a predominant strain type (USA300), necessitates re-evaluation of the discriminatory power of these typing methods for discerning molecular epidemiology and transmission dynamics, essential to investigations of hospital and community outbreaks. We compared the discriminatory index of 5 typing methods for contemporary S. aureus strain characterization. Children presenting to St. Louis Children's Hospital and community pediatric practices in St. Louis, Missouri (MO), with community-associated S. aureus infections were enrolled. Repetitive sequence-based PCR (repPCR), pulsed-field gel electrophoresis (PFGE), multilocus sequence typing (MLST), staphylococcal protein A (spa), and staphylococcal cassette chromosome (SCC) mec typing were performed on 200 S. aureus isolates. The discriminatory index of each method was calculated using the standard formula for this metric, where a value of 1 is highly discriminatory and a value of 0 is not discriminatory. Overall, we identified 26 distinct strain types by repPCR, 17 strain types by PFGE, 30 strain types by MLST, 68 strain types by spa typing, and 5 strain types by SCCmec typing. RepPCR had the highest discriminatory index (D) of all methods (D = 0.88), followed by spa typing (D = 0.87), MLST (D = 0.84), PFGE (D = 0.76), and SCCmec typing (D = 0.60). The method with the highest D among MRSA isolates was repPCR (D = 0.64) followed by spa typing (D = 0.45) and MLST (D = 0.44). The method with the highest D among MSSA isolates was spa typing (D = 0.98), followed by MLST (D = 0.93), repPCR (D = 0.92), and PFGE (D = 0.89). Among isolates designated USA300 by PFGE, repPCR was most discriminatory, with 10 distinct strain types identified (D = 0.63). We identified 45

    2015-01-01

    To present the theoretical basis for the group process known as "Peace and Power." A dialectic between two dominant forms of power-peace powers and power-over powers-forms the basis for a synthesis that yields an emancipatory group process characterized by praxis, empowerment, awareness, cooperation, and evolvement for individuals and groups. Critical analysis of prevailing competitive group dynamics and the ideals of cooperative group dynamics was conducted to project the potential for achieving group interactions that yield profound changes in the direction of justice, empowerment, and well-being for all. The theoretical framework of "Peace and Power" is consistent with characteristics of emancipatory integrity that are vital for social change. The processes of "Peace and Power" can be used to create peaceful, cooperative interactions among nurses, with other health professionals, with patients and families, and in communities. © 2014 Sigma Theta Tau International.

    Social dominance theory was developed to account for why societies producing surplus take and maintain the form of group-based dominance hierarchies, in which at least one socially-constructed group has more power than another, and in which men are more powerful than women and adults more powerful than children. Although the theory has always allowed for societies to differ in their severity of group-based dominance and how it is implemented, it has predicted that alternative forms of societa...

  16. Intrinsic thermoelectric power of group VB metals

    2012-03-01

    Full Text Available We have reinvestigated the thermopower of group VB metals in polycrystalline forms in the temperature range of 6-300K, taking into account the critical nature of the sample surface and heat treatment especially for niobium. Strikingly small magnitude, negative sign, phonon drag dip and superconductivity not reported previously were observed in surface-cleaned single crystalline Nb. However, while thermopower magnitudes are small, mixed signs were found in the polycrystalline V, Nb and Ta samples. These properties were therefore interpreted as their intrinsic properties and were briefly discussed taking into account of the existing theory by fitting also the data that give the Fermi energies of 10.94 eV, 5.08 eV and 1.86eV, respectively.

  17. When does power disparity help or hurt group performance?

    2016-03-01

    Power differences are ubiquitous in social settings. However, the question of whether groups with higher or lower power disparity achieve better performance has thus far received conflicting answers. To address this issue, we identify 3 underlying assumptions in the literature that may have led to these divergent findings, including a myopic focus on static hierarchies, an assumption that those at the top of hierarchies are competent at group tasks, and an assumption that equality is not possible. We employ a multimethod set of studies to examine these assumptions and to understand when power disparity will help or harm group performance. First, our agent-based simulation analyses show that by unpacking these common implicit assumptions in power research, we can explain earlier disparate findings--power disparity benefits group performance when it is dynamically aligned with the power holder's task competence, and harms group performance when held constant and/or is not aligned with task competence. Second, our empirical findings in both a field study of fraud investigation groups and a multiround laboratory study corroborate the simulation results. We thereby contribute to research on power by highlighting a dynamic understanding of power in groups and explaining how current implicit assumptions may lead to opposing findings.

    2000-06-01

    Facing the new law on the electric power market liberalization, the french government created an experts group to analyze solutions and assessment methods of the electrical networks costs and tariffs and to control their efficiency. This report presents the analysis and the conclusions of the group. It concerns the three main subjects: the regulation context, the tariffing of the electric power transmission and distribution (the cost and efficiency of the various options) and the tariffing of the electric power supply to the eligible consumers. The authors provide a guideline for a tariffing policy. (A.L.B.)

    Using an optical sensor, to automatically evaluate the marginal seal of restorations placed with 21 adhesive systems of all four adhesive categories in cylindrical cavities of bovine dentin applying different outcome variables, and to evaluate their discriminatory power. Twenty-one adhesive systems were evaluated: three 3-step etch-and-rinse systems, three 2-step etch-and-rinse systems, five 2-step self-etching systems, and ten 1-step self-etching systems. All adhesives were applied in cylindrical cavities in bovine dentin together with Tetric Ceram (n=8). In the control group, no adhesive system was used. After 24 h of storage in water at 37 degrees C, the surface was polished with 4000-grit SiC paper, and epoxy resin replicas were produced. An optical sensor (FRT MicroProf) created 100 profiles of the restoration margin, and an algorithm detected gaps and calculated their depths and widths. The following evaluation criteria were used: percentage of specimens without gaps, the percentage of gap-free profiles in relation to all profiles per specimen, mean gap width, mean gap depth, largest gap, modified marginal integrity index MI. The statistical analysis was carried out on log-transformed data for all variables with ANOVA and post-hoc Tukey's test for multiple comparisons. The correlation between the variables was tested with regression analysis, and the pooled data accordingto the four adhesive categories were compared by applying the Mann-Whitney nonparametric test (p adhesive systems demonstrated the best marginal adaptation, followed by the 2-step self-etching and the 1-step self-etching adhesives; the latter showed the highest variability in test results between materials and within the same material. The only exception to this rule was Xeno IV, which showed a marginal adaptation that was comparable to that of the best 3-step etch-and-rinse systems. Except for the variables "largest gap" and "mean gap depth", all the other variables had a similar ability to

    2017-02-01

    Full Text Available This paper presents an analytical model of group based hand-off management based on bird flocking behavior. In the proposed scheme, a number of mobile devices form a group if these devices move together for a long time duration. Although call delivery or call generation are performed individually, hand-off is performed in a group. Dynamic group formation, group division and group merging methods are proposed in this paper. From the simulation results it is demonstrated that approximately 75%, 65% and 90% reduction in power, cost and latency consumption can be obtained respectively using group hand-off management. Thus the proposed scheme is referred as green, economic and fast hand-off strategy. In this paper instead of a macrocell network, a microcell-femtocell network is considered as the transmission power of a microcell or a femtocell base station is much less than a macrocell base station. Simulation results present that the microcell-femtocell network achieves approximately 25–55% and 35–55% reduction in power transmission, and 50–65% and 15–45% reduction in path loss than only a macrocell network and macrocell-femtocell network respectively. Thus microcell-femtocell network is a power-efficient network.

    We study the amenability property for the group J(k) of formal power series in one variable with coefficients in a commutative ring k with identity. We show that there exists an invariant mean on the space C{sub u}*(J(k)) of uniformly continuous bounded functions on this group. This is equivalent to the fact that every continuous action of J(k) on every compact space has an invariant probability measure.

  3. Standard compensation for power cuts. Working group report

    International Nuclear Information System (INIS)

    2002-07-01

    The Working Group was commissioned to draw up a proposal in the form of a Government Bill for provisions to be included in the Electricity Market Act on imposing an obligation on the distribution net operator to pay a standard compensation to the users of electricity for the event that they get no access to electricity. The Working Group should consider especially a model of standard compensation presented in the final report by Mr. Jarl Forsten, Deputy Director General of the Technical Research Centre of Finland VTT, published on 30 April 2002 that the amount of standard compensation should not depend on the reason for the power cut. The Working Group proposes that the Electricity Market Act should be amended by provisions providing that a distribution net operator shall pay to the user of electricity a standard compensation for power cuts lasting over 12 hours. The amount of compensation shall be based on the annual network service fee and a sliding scale of compensation related to the duration of the power cut shall be applied. The maximum compensation shall be paid when the power cut lasts more than five days. The maximum amount of individual compensations shall be fixed at EUR 700. The proposed provisions on standard compensation in the event of power cuts are aimed at amending the provisions in Chapter 6a of the Electricity Market Act on price reduction and compensation because of fault in the supply of electricity. The aim of the introduction of standard compensation for power cuts is to persuade distribution net operators to make an effort to minimize the time for power cuts. (orig.)

  4. Endomorphism Algebras of Tensor Powers of Modules for Quantum Groups

    We determine the ring structure of the endomorphism algebra of certain tensor powers of modules for the quantum group of sl2 in the case where the quantum parameter is allowed to be a root of unity. In this case there exists -- under a suitable localization of our ground ring -- a surjection from...... the group algebra of the braid group to the endomorphism algebra of any tensor power of the Weyl module with highest weight 2. We take a first step towards determining the kernel of this map by reformulating well-known results on the semisimplicity of the Birman-Murakami-Wenzl algebra in terms of the order...... of the quantum parameter. Before we arrive at these main results, we investigate the structure of the endomorphism algebra of the tensor square of any Weyl module....

    Full Text Available Social dominance theory was developed to account for why societies producing surplus take and maintain the form of group-based dominance hierarchies, in which at least one socially-constructed group has more power than another, and in which men are more powerful than women and adults more powerful than children. Although the theory has always allowed for societies to differ in their severity of group-based dominance and how it is implemented, it has predicted that alternative forms of societal organization will occur rarely and not last. This paper revisits aspects of the theory that allow for the possibility of societal alternatives and change. We also consider boundary conditions for the theory, and whether its current theoretical apparatus can account for societal change. By expanding the typical three-level dynamic system to describe societies (micro-meso-macro into four levels (including meta to consider how societies relate to one another, we identify political tensions that are unstable power structures rather than stable hierarchies. In research on institutions, we identify smaller-scale alternative forms of social organization. We identify logical, empirical, and theoretical shortcomings in social dominance theory’s account of stability and change, consider alternative forms of social organization, and suggest fruitful avenues for theoretical extension.

    Full Text Available Type II diabetes is a chronic condition that affects the way our body metabolizes sugar. The body's important source of fuel is now becoming a chronic disease all over the world. It is now very necessary to identify the new potential targets for the drugs which not only control the disease but also can treat it. Support vector machines are the classifier which has a potential to make a classification of the discriminatory genes and non-discriminatory genes. SVMRFE a modification of SVM ranks the genes based on their discriminatory power and eliminate the genes which are not involved in causing the disease. A gene regulatory network has been formed with the top ranked coding genes to identify their role in causing diabetes. To further validate the results pathway study was performed to identify the involvement of the coding genes in type II diabetes. The genes obtained from this study showed a significant involvement in causing the disease, which may be used as a potential drug target.

    2017-10-01

    Full Text Available The article focuses on the application of social psychology, and visual technologies, such as photography. It stresses that this type of visual technology is used in research aimed at the study of communication, interpersonal knowledge, and inter-ethnic relations. Within these areas of research we apply photos of human appearance with the status of the criterion of categorization, identification, classification, the mechanism of recognition of certain social and ethnic groups, and attitudes. So far visual technology was insufficiently applied in studying relationships in various discriminatory practices including discrimination, which is designated as ethnic-lookism. The work discusses researches that studied identification and assessment of the man's face of different races through the application of visual technologies. The authors come to the conclusion, that the visual experience in the mainstreaming of discriminatory practices including ethnic-lookism becomes a promising direction in studying the attitudes to discriminatory behaviour in various situations of interaction.

    Subjective health measurements are increasingly used in clinical research, particularly for patient groups comparisons. Two main types of analytical strategies can be used for such data: so-called classical test theory (CTT), relying on observed scores and models coming from Item Response Theory (IRT) relying on a response model relating the items responses to a latent parameter, often called latent trait. Whether IRT or CTT would be the most appropriate method to compare two independent groups of patients on a patient reported outcomes measurement remains unknown and was investigated using simulations. For CTT-based analyses, groups comparison was performed using t-test on the scores. For IRT-based analyses, several methods were compared, according to whether the Rasch model was considered with random effects or with fixed effects, and the group effect was included as a covariate or not. Individual latent traits values were estimated using either a deterministic method or by stochastic approaches. Latent traits were then compared with a t-test. Finally, a two-steps method was performed to compare the latent trait distributions, and a Wald test was performed to test the group effect in the Rasch model including group covariates. The only unbiased IRT-based method was the group covariate Wald's test, performed on the random effects Rasch model. This model displayed the highest observed power, which was similar to the power using the score t-test. These results need to be extended to the case frequently encountered in practice where data are missing and possibly informative.

  13. Government's role in power supply security. A working group report

    International Nuclear Information System (INIS)

    2004-01-01

    The working group was to analyse the Government's role in terms of improving the security of supply of the electricity market in exceptionally difficult capacity situations and to make propositions for the ways of arranging a tendering procedure concerning security of supply and capacity control, so as to meet the requirements of the EC Energy Internal Market Directives after 1 July 2004. The Working Group considers that there is no need at this stage to introduce a separate new system intended as a supplement to technical reserves in Finland. Such a system would not bring new capacity for the use of the power system, and in the case of existing capacity, production would only be transferred from one market to another. However, the situation may change from this, if there occur such factors on the market that aim to raise the market price of electricity or if it turned out that reserve power plants would be decommissioned on a large scale. The working group proposes that such a provision be added to the Electricity Market Act that would oblige the electricity supplier to notify the Energy Market Authority of a planned service outage of a power plant of at least 100 MVA producing electricity separately, which would fall within the time period 1 December - 28 February. The Energy Market Authority would be vested with the powers to postpone the outage due to a tight output situation, if there are not technical or safety- bound obstacles to this. It is important for the sufficiency of the power need of the Internal Market that the price signals of the market are reflected to both producers and consumers of electricity. The working group further proposes that the Ministry of Trade and Industry would look into development of the meter-reading requirements, so that they would, for their part, create the conditions for price flexibility in power consumption and for new sales products of electricity. In addition, tightening of the hourly metering requirement related to the

    Full Text Available We defend the importance of studying the discriminatory treatment of criminal law from the analysis of discourses on the subjectivities, resulting in dichotomy citizen/enemy. Rationalisations about the category of enemy in so-called "law of risk", seem to justify the unequal exercise of power punitive and the neutralization of individuals labelled as harmful and abnormal behavior, even if this is at the expense of principles, fundamental rights and guarantees of the rule of law. Such discourses also favors the neoliberal environment, to the extent that translate the entire conflitividade on punishment and legitimized stigmatization processes, criminalization of poverty and criminal selectivity.

    Highlights: • A direct fitting multi-group pin power reconstruction method is developed. • The 1D nodal solution flux profiles are used as the condition. • The least square fit problem is analytically solved. • A slowing down source improvement method is applied. • The method shows good accuracy for even challenging problems. - Abstract: A group-decoupled direct fitting method is developed for multi-group pin power reconstruction, which avoids both the complication of obtaining 2D analytic multi-group flux solution and any group-coupled iteration. A unique feature of the method is that in addition to nodal volume and surface average fluxes and corner fluxes, transversely-integrated 1D nodal solution flux profiles are also used as the condition to determine the 2D intra-nodal flux distribution. For each energy group, a two-dimensional expansion with a nine-term polynomial and eight hyperbolic functions is used to perform a constrained least square fit to the 1D intra-nodal flux solution profiles. The constraints are on the conservation of nodal volume and surface average fluxes and corner fluxes. Instead of solving the constrained least square fit problem numerically, we solve it analytically by fully utilizing the symmetry property of the expansion functions. Each of the 17 unknown expansion coefficients is expressed in terms of nodal volume and surface average fluxes, corner fluxes and transversely-integrated flux values. To determine the unknown corner fluxes, a set of linear algebraic equations involving corner fluxes is established via using the current conservation condition on all corners. Moreover, an optional slowing down source improvement method is also developed to further enhance the accuracy of the reconstructed flux distribution if needed. Two test examples are shown with very good results. One is a four-group BWR mini-core problem with all control blades inserted and the other is the seven-group OECD NEA MOX benchmark, C5G7

    Full Text Available The text aims to present less visible facet of discrimination by identifying social and cultural mechanisms that generate and maintain multiple forms of discrimination, the intersection of which gender has a central position, because he combine with all other criteria of discrimination (race, ethnicity, nationality, religion, social class, age, disability, multiplying the effect of discriminatory behavior. This paper highlights the gender inequalities, the disparities between women and men, boys and girls who are socially constructed which are produced in the process of education and differential gender socialization, asymmetric and hierarchical, correlated with educational and professional orientation and also with labor market access and situation. The fact that gender inequalities exist at a structural level and they are deeply rooted in social practices and collective mental lead to situations where discriminatory behavior manifested without being noticed and as less as sanctioned.

  18. Sequence-based classification using discriminatory motif feature selection.

    Directory of Open Access Journals (Sweden)

    Hao Xiong

    Full Text Available Most existing methods for sequence-based classification use exhaustive feature generation, employing, for example, all k-mer patterns. The motivation behind such (enumerative approaches is to minimize the potential for overlooking important features. However, there are shortcomings to this strategy. First, practical constraints limit the scope of exhaustive feature generation to patterns of length ≤ k, such that potentially important, longer (> k predictors are not considered. Second, features so generated exhibit strong dependencies, which can complicate understanding of derived classification rules. Third, and most importantly, numerous irrelevant features are created. These concerns can compromise prediction and interpretation. While remedies have been proposed, they tend to be problem-specific and not broadly applicable. Here, we develop a generally applicable methodology, and an attendant software pipeline, that is predicated on discriminatory motif finding. In addition to the traditional training and validation partitions, our framework entails a third level of data partitioning, a discovery partition. A discriminatory motif finder is used on sequences and associated class labels in the discovery partition to yield a (small set of features. These features are then used as inputs to a classifier in the training partition. Finally, performance assessment occurs on the validation partition. Important attributes of our approach are its modularity (any discriminatory motif finder and any classifier can be deployed and its universality (all data, including sequences that are unaligned and/or of unequal length, can be accommodated. We illustrate our approach on two nucleosome occupancy datasets and a protein solubility dataset, previously analyzed using enumerative feature generation. Our method achieves excellent performance results, with and without optimization of classifier tuning parameters. A Python pipeline implementing the approach is

    Power relations affect dynamics within groups. Power-holders' decisions not only determine their personal outcomes, but also the outcomes of others in the group that they control. Yet, power-holders often tend to overlook this responsibility to take care of collective interests. The present research investigated how social identification - with the group to which both the powerful and the powerless belong - alters perceived responsibility among power-holders (and the powerless). Combining research on social power and social identity, we argue that power-holders perceive more responsibility than the powerless when strongly (rather than when weakly) identifying with the group. A study among leaders and an experiment supported this, highlighting that although power-holders are often primarily concerned about personal outcomes, they do feel responsible for considering others' interests when these others are included in the (social) self. © 2017 The British Psychological Society.

    Full Text Available Using dictator games in experimental analysis, this lesson report demonstrates the process and results of a postgraduate class project in which university students were instructed to scientifically investigate and explore one of German society’s most hotly-contested issues: the level of discriminatory tendencies of non-Muslims towards Muslims. The results of this class project show little or no discriminatory tendencies toward Muslims. Instead, the university students under our investigation tended to act favorably, or at the very least, fairly toward Muslims. We expect that this lesson report can demonstrate how a postgraduate course can be conducted in an innovative way, empowering students to collect primary data and finishing a small scientific project during the span of a semester.

    Objective: To explore the factors correlative with the early hypothyroidism after 131 I therapy for Graves' hyperthyroidism so as to cure it and decrease the early hypothyroidism occurring and prevent it from becoming irreversible hypothyroidism. Methods: Logistic regression discriminatory analysis by introducing multiple factors from group data and forward stepwise selection of 11 independent variables of 240 hyperthyroidism patients from clinical data and 1 dependent variable from follow-up data after 131 I therapy was conducted. Univariate analysis of each observed factor was performed, too. Results: (1)The results of multivariate analysis showed that the age of patients, the weight of thyroid, the suffering situation, the curve of 131 I absorption rate and the giving 131 I dosage/g thyroid tissue were correlated to early hypothyroidism. The results of univariate analysis showed that the weight of thyroid, the highest absorption of 131 I, the total treatment dosage of 131 I were correlated to early hypothyroidism. (2) The logistic regression equation was statistically significant. (3) The positive and negative predicting accuracy of the early hypothyroidism occurring was 64.08 %, 78.83 %, respectively, the overall predicting accuracy was 72.50%. Conclusions: The dosage of 131 I for treatment of hyperthyroid is the key factor according to the five correlative factors which are relating to the early hypothyroidism and the discriminatory classification. Enhanced follow-up and in time supplement of thyroid hormone are important measures for preventing the early hypothyroidism from becoming irreversible hypothyroidism

    2007-01-01

    Full Text Available This article presents findings from a quantitative survey (N = 301 to evaluate the impact discriminatory incidents have on the attitudes of immigrants towards the majority society in Germany.The findings show that there is a strong relationship between experiences of discrimination and a hostile or alienated attitude towards German society. As an attempt to explain this generalization from single incidents to the macro relation between immigrants and autochthonous Germans in general a theory of framing, taken from developments in the field of rational choice theory, is applied. The reasoning is that a generalizing and rather hostile framing in terms of the attitude towards Germans can minimize psychic, emotional and social costs resulting from acts of discrimination.

    To investigate the possibility that Koreans show different patterns in reporting discriminatory experiences based on their gender and education level, we analyzed the participants who answered "Not Applicable" for the questions of discriminatory experiences that they were eligible to answer. Discriminatory experiences in eight social situations were assessed using the 7(th) wave of Korean Labor and Income Panel Study. After restricting the study population to waged workers, a logistic regression model was constructed to predict the probability that an individual has experienced discrimination based on the observed covariates for each of eight situations, using the data of participants who answered either Yes or No. With the model fit, the predicted logit score of discrimination (PLSD) was obtained for participants who answered Not Applicable (NA), as well as for those who answered Yes or No. The mean PLSD of the NA group was compared with those of the Yes group and the No group after stratification by gender and education level using an ANOVA model. On the questions of discrimination in getting hired and receiving income, the PLSD of the NA group was significantly higher than that of the No group and was not different from that of Yes group for female and junior high or less educated workers, suggesting that their NA responses were more likely to mean that they have experienced discrimination. For male and college or more educated workers, the NA group had a PLSD similar to that for the No group and had a significantly higher PLSD than the Yes group, implying that their NA responses would mean they that they have not experienced discrimination. Our findings suggest that the responses of NA on the discrimination questionnaire may need different interpretation based on the respondents' gender and education level in South Korea.

    Creativity and innovation are evergreen topics. Particularly in today's tough marketplace, companies in every industry are looking for ways to harness creativity and innovation to spur growth and enhance competitiveness. This book differs from many books on creativity in that its focus is on how to manage a group, rather than individual creativity. It refutes much conventional wisdom about where creativity comes from, particularly that creativity does not stem from the random genius of individuals. The authors reveal specific group configurations and strategies that can unleash the collective creativity of any team or group.

    The prevalence of mental disorders in Mexico is 26.1%. This shows that an important percentage of the population suffers from mental disability. Despite this the country's healthcare system does not provide the least acceptable standard of care for the mentally disabled. The aim of this study was to describe the general population's social representations of the disabled and analyze their relationship with the discriminatory practices from the state towards the mentally ill with respect to their right to health. This study was a secondary analysis of the First National Survey on Discrimination in Mexico. In the survey 1,437 effective interviews that comprised a representative sample, were obtained from people aged 18 to 60 living in rural and urban settings. The response rate was 76.5%. The assessment tool was a self-administered questionnaire that yielded perceptions, attitudes, values and social representations about discrimination towards groups of people that supposedly were targets of discrimination by the general population. In the survey the mentally ill were included under disability. As a secondary analysis of the survey for the purpose of this study, we selected a subset of questions that provided important information about social representations of the general Mexican population towards persons with disabilities. The general population's social representations of the disabled were analyzed. The disabled are the second group after the elderly perceived as the most discriminated and neglected and bearing more suffering. A whole set of negative representations concerning the disabled, such as lack of acceptance and respect, low self-confidence, mistreatment, incomprehension, isolation, intolerance, indifference and bad attitudes from others, were elicited. Social representations are social correspondents of the discriminatory practices that the state exerts toward the mentally ill with respect to their right to health. These representations serve to

    First Nations and Metis communities are now initiating and managing projects in the Canadian energy sector. Federal and provincial governments are now developing training programs to ensure that Aboriginal communities develop the skills needed to successfully manage energy projects. The Supreme Court of Canada has issued a number of rulings ensuring that companies and government agencies have a duty to consult with Aboriginal people when Crown decisions impact Treaty or Aboriginal rights. The Ministry of Energy and Infrastructure has now set up a unit to provide advice and guidance to facilitate partnership opportunities with First Nations and Metis communities. Major companies in Ontario have also developed consultation policies that focus on relationship building, internal education, and promoting business and workforce development. The Pic River First Nation group now owns a minority interest in the Wawatay generating station. A 23 MW facility is fully owned by the First Nations group. The province of Ontario has made a provision for up to $250 million to serve as loan guarantees for First Nations groups. It was concluded that the Electricity Sector Council (ESC) has developed an Aboriginal participation engagement project designed to increase Aboriginal awareness of opportunities within the electricity and renewable energy sector. 3 figs.

  11. Attracted to power: challenge/threat and promotion/prevention focus differentially predict the attractiveness of group power

    2015-01-01

    Depending on their motivation, individuals prefer different group contexts for social interactions. The present research sought to provide more insight into this relationship. More specifically, we tested how challenge/threat and a promotion/prevention focus predict attraction to groups with high- or low-power. As such, we examined differential outcomes of threat and prevention focus as well as challenge and promotion focus that have often been regarded as closely related. According to regulatory focus, individuals should prefer groups that they expect to “feel right” for them to join: Low-power groups should be more attractive in a prevention (than a promotion) focus, as these groups suggest security-oriented strategies, which fit a prevention focus. High-power groups should be more attractive in a promotion (rather than a prevention) focus, as these groups are associated with promotion strategies fitting a promotion focus (Sassenberg et al., 2007). In contrast, under threat (vs. challenge), groups that allow individuals to restore their (perceived) lack of control should be preferred: Low-power groups should be less attractive under threat (than challenge) because they provide low resources which threatened individuals already perceive as insufficient and high-power groups might be more attractive under threat (than under challenge), because their high resources allow individuals to restore control. Two experiments (N = 140) supported these predictions. The attractiveness of a group often depends on the motivation to engage in what fits (i.e., prefer a group that feels right in the light of one’s regulatory focus). However, under threat the striving to restore control (i.e., prefer a group allowing them to change the status quo under threat vs. challenge) overrides the fit effect, which may in turn guide individuals’ behavior in social interactions.

  12. Differential reporting of discriminatory experiences in Brazil and the United States

    Directory of Open Access Journals (Sweden)

    Sarah Burgard

    Full Text Available Abstract: There has been little cross-national comparison of perceived discrimination, and few studies have considered how intersectional identities shape perception of discriminatory treatment in different societies. Using data from the ELSA-Brasil, a study of Brazilian civil servants, and the Americans’ Changing Lives Study, a nationally-representative sample of U.S. adults, we compare reports of lifetime discrimination among race-by-gender groups in each society. We also consider whether educational attainment explains any group differences, or if differences across groups vary by level of education. Results reveal higher lifetime discrimination experiences among Black respondents in both countries, especially Black men, than among Whites, and lower reports among White women than White men. Brown men and women also reported higher levels than White men in Brazil. For all race-by-gender groups in both countries, except Brazilian White men, reports of discrimination were higher among the more educated, though adjusting for educational differences across groups did not explain group differences. In Brazil, we found the greatest racial disparities among the college educated, while U.S. Black men were more likely to report discrimination than White men at all levels of education. Results reveal broad similarities across countries, despite important differences in their histories, and an intersectional approach contributed to identification of these similarities and some differences in discrimination experiences. These findings have implications for social and public health surveillance and intervention to address the harmful consequences of discrimination.

    An extensive body of literature exists on the obstacles that have to be overcome in green power retailing. In this article, target group-specific marketing is evaluated as a strategy to increase the share of residential customers of green power. A sample of students in the city of Freiburg, Germany was interviewed in order to assess their awareness of environmental issues, their willingness to change to green power products, and to better understand individual hindrances in changing the power supplier. The analysis shows that students are highly positive towards green power products, but for several reasons difficult to reach in marketing campaigns. Aspects to be considered in addressing this consumer-group include the students' particular expectations towards green products, their living-conditions, price sensitivity, and their perception of the relative effort involved in changing the power provider.

    A method to design the distribution and composition of nuclear fuel for the array of fuel rods in a lattice for BWRs is presented in this work. The aim of the method is to minimize the power peaking factor until an adequate value is reached. Also, this method uses a few calculations of lattice. The method is based on the classification of the fuel rods in two groups: the group of fuel rods with the higher power level (group pow ), and the other group of fuel rods (no-group pow ). The enrichment of 235 U of each fuel rod of the group pow is multiplied by a factor called group fissile factor (f group ), and the enrichment of 235 U of each fuel rod of the no-group pow is multiplied by a factor called no-group fissile factor (f no-group ). These factors are fitted so that the power peaking factor is minimized. The importance of the method with the use of these two factors is applied to the design of a fuel lattice for BWRs as the Laguna Verde nuclear power plant. The calculations of lattice are made by means of the Helios code. (Author)

    1996-01-01

    A three year survey, beginning in 1991, was conducted by the Canadian Electrical Association to study the levels of power quality that exist in Canada, and to determine ways to increase utility expertise in making power quality measurements. Twenty-two utilities across Canada were involved, with a total of 550 sites being monitored, including residential and commercial customers. Power disturbances, power outages and power quality were recorded for each site. To create a group average power quality plot, the transient disturbance activity for each site was normalized to a per channel, per month basis and then divided into a grid. Results showed that the average power quality provided by Canadian utilities was very good. Almost all the electrical disturbance within a customer premises were created and stayed within those premises. Disturbances were generally beyond utility control. Utilities could, however, reduce the amount of time the steady-state voltage exceeds the CSA normal voltage upper limit. 5 figs

    2016-01-01

    Full Text Available We can easily come to the conclusion that the general settings of the theory of social interactionism, and especially the process of social labeling and stigmatization, as a concretization of those theories, can serve as a basis for explaining certain aspects of discriminatory activities in policing. And this problem is a key subject of this work, which we tried to explain in the light of three different but inter-related labeling theory. In this way, we also wanted to find their practical application in a particular social phenomenon or as it is popularly said 'to put theory into operation'. In fact, the key purpose of this paper is to show how the interaction of social subjects, which takes place at a general level, particularly categorization, classification, social stigma and stereotypes that result from these interactions, significantly shape the way the police behave. Moreover, if we take into consideration that police officers have a significant level of power to label others from the position of professional authority this theoretical concept becomes more important. To what extent (of course, empirically speaking this social process affects in such a way and creates such consequences, it should be established by a scientific investigation of individual cases. It is certain, however, that our life often assures us of this outcome, confirming that it is not a coincidence, but the unwritten rules. And such examples should serve us as a starting point for scientific research of this phenomenon.

  3. Design and validation of a highly discriminatory 10-locus Y-chromosome STR multiplex system

    2011-03-01

    The Y-chromosome STRs (short tandem repeat) markers are routinely utilized in the resolution of forensic casework related to sexual assault. For this, the forensic community has adopted a set of eleven (core) Y-STR that is incorporated in all commercial diagnostic systems. Our previous studies of Y-STR polymorphisms in the South African population identified low levels of diversity and discrimination capacity for many commercial marker sets, determining a limited applicability of these systems to the local population groups. To overcome this shortcoming, we designed a Y-STR 10-plex system that shows higher discriminatory capacity (DC) than available commercial systems. The markers were selected from a population group of 283 individuals with African, European and Asian ancestry genotyped at 45 Y-STRs, applying an optimization based selection procedure to achieve the highest possible DC with the minimal number of markers. The 10-plex was satisfactorily subjected to developmental validation tests following the SWGDAM guidelines and shows potential for its application to genealogical and evolutionary studies. © 2010 Elsevier Ireland Ltd.

    Full Text Available As an effective aggregation tool, power average (PA allows the input arguments being aggregated to support and reinforce each other, which provides more versatility in the information aggregation process. Under the probabilistic linguistic term environment, we deeply investigate the new power aggregation (PA operators for fusing the probabilistic linguistic term sets (PLTSs. In this paper, we firstly develop the probabilistic linguistic power average (PLPA, the weighted probabilistic linguistic power average (WPLPA operators, the probabilistic linguistic power geometric (PLPG and the weighted probabilistic linguistic power geometric (WPLPG operators. At the same time, we carefully analyze the properties of these new aggregation operators. With the aid of the WPLPA and WPLPG operators, we further design the approaches for the application of multi-criteria group decision-making (MCGDM with PLTSs. Finally, we use an illustrated example to expound our proposed methods and verify their performances.

    Full Text Available Electrical Power Network in recent time requires an intelligent, virtual environment based decision process for the coordination of all its individual elements and the interrelated tasks. Its ultimate goal is to achieve maximum productivity and efficiency through the efficient and effective application of generation, transmission, distribution, pricing and regulatory systems. However, the complexity of electrical power network and the presence of conflicting multiple goals and objectives postulated by various groups emphasized the need of an intelligent group decision support system approach in this field. In this paper, an Integrated Multimedia based Intelligent Group Decision Support System (IM1GDSS is presented, and its main components are analyzed and discussed. In particular attention is focused on the Data Base, Model Base, Central Black Board (CBB and Multicriteria Futuristic Decision Process (MFDP module. The model base interacts with Electrical Power Network Load Forecasting and Planning (EPNLFP Module; Resource Optimization, Modeling and Simulation (ROMAS Module; Electrical Power Network Control and Evaluation Process (EPNCAEP Module, and MFDP Module through CBB for strategic planning, management control, operational planning and transaction processing. The richness of multimedia channels adds a totally new dimension in a group decision making for Electrical Power Network. The proposed IMIGDSS is a user friendly, highly interactive group decision making system, based on efficient intelligent and multimedia communication support for group discussions, retrieval of content and multi criteria decision analysis.

    Full Text Available Background: Helicobacter pylori is a major human gastric for various gastro duodenal diseases.A number of putative virulence factors such as dupA, homB, tnpA have been described. To date,none were found to be significantly associated with specific H. pylori-related diseases (e.g. gastric cancer and duodenal ulcer.Methods: the primary aim of this study was to test the H. pylori hrgA genotype isolated from 253 Iranian symptomatic patients to investigate possible association with clinical outcomes. The positive culture results were confirmed by glmM (genetic control for H. pylori PCR assay.Results: The results showed hrgA gene was detected in 44/253 strains (17.3%. Prevalence of the hrgA gene was relatively high in strains isolated from duodenal ulcer patients (P=0.0063; Odd ratio: 3.54; CI 95%: 1.42-8.77.Conclusions: In contrast our findings showed that the prevalence of hrgA in our control group (gastritis patients was 22.7% (P>0.05. Conclusively, hrgA gene is a good candidate as a discriminatory biomarker for patients with duodenal ulcer

  8. The Method of Optimization of Hydropower Plant Performance for Use in Group Active Power Controller

    Full Text Available The problem of optimization of hydropower plant performance is considered in this paper. A new method of calculation of optimal load-sharing is proposed. The method is based on application of incremental water flow curves representing relationship between the per unit increase of water flow and active power. The optimal load-sharing is obtained by solving the nonlinear equation governing the balance of total active power and the station power set point with the same specific increase of water flow for all turbines. Unlike traditional optimization techniques, the solution of the equation is obtained without taking into account unit safe operating zones. Instead, if calculated active power of a unit violates the permissible power range, load-sharing is recalculated for the remaining generating units. Thus, optimal load-sharing algorithm suitable for digital control systems is developed. The proposed algorithm is implemented in group active power controller in Novosibirsk hydropower plant. An analysis of operation of group active power controller proves that the application of the proposed method allows obtaining optimal load-sharing at each control step with sufficient precision.

    2010-01-01

    Only four states used auction in Phase Ⅰ (2005-2007) of the European Union Emission Trading System, of which four used a uniform-price sealed auction format. Here we discuss whether the auction should adopt a uniform-price or discriminatory-price format using an agent-based carbon allowances...... auction model established for the purpose. The main conclusions are as follows: (1) when carbon allowances are relatively scarce, the government should use a discriminatory-price auction; when carbon allowances are relatively abundant, the government should use a uniform-price auction. (2) Uncertainty......) The uniform-price auction is relatively insensitive to market structure. However, a monopoly market is more likely to develop under the discriminatory-price auction format. The results of the model have some policy implications for designing carbon market mechanisms in the future....

    In this paper, we report a linear polarization-discriminatory state inverter made of three-layer sculpture thin film fabricated by oblique angle deposition technique. The first and third layers are quarter-wave plates of zigzag structure and the middle of them is a circular Bragg reflector of left-handed helical structure. It is found that the normal incidence of P-polarized light on this polarization-discriminatory state inverter becomes the S-polarized light at output, while the incident S-polarized light of wavelength lying in the Bragg regime is reflected. The microstructure of the linear polarization-discriminatory state inverter is also investigated by using a scanning electron microscope.

    Full Text Available Discrimination is a complex phenomenon with adverse consequences at personal and organisational levels. Past studies have demonstrated that workers who are victims of discrimination might show less job satisfaction, less organisational commitment and worse levels of health and productivity. Although most research has focused on the effects of discrimination on victims, less is known about the extent to which discrimination produces consequences on workers who perceive the existence of a discriminatory work environment. The goal of this article is to analyse the consequences of the perception of a discriminatory work environment on employees’ health. The importance of this relationship is studied taking into account the mediating effect of job satisfaction. In order to reach this goal a cross-sectional study was carried out with a sample of 1633 Italian workers (male= 826, female= 764, employed in private and public sectors, and in different hierarchical positions. Results suggest that the perception of a discriminatory work environment is negatively associated with employees’ health. This relationship is partially mediated by job satisfaction (R²= .17. This study demonstrates that perceiving a discriminatory work environment might have a negative impact on workers’ health. A higher level of job satisfaction might buffer this effect. These findings have several practical implications. On the one hand, Human Resource Managers need to intervene in order to recognise and diminish implicit biases, creating a healthy and inclusive environment (e.g. through training, diversity policies, etc.. On the other hand, promoting job satisfaction (e.g. providing mechanisms of voice might help workers to preserve their well-being, coping with the negative effects of a discriminatory work environment.Keywords: Discriminatory work environment, Job satisfaction, Employees’ health, Human Resource Management, Italian workers, Workplace, Work-related stress

    C-tactile afferents (CTs) are slowly conducting nerve fibres, present only in hairy skin. They are optimally activated by slow, gentle stroking touch, such as those experienced during a caress. CT stimulation activates affective processing brain regions, alluding to their role in affective touch perception. We tested a theory that CT-activating touch engages the pro-social functions of serotonin, by determining whether reducing serotonin, through acute tryptophan depletion, diminishes subjective pleasantness and affective brain responses to gentle touch. A tryptophan depleting amino acid drink was administered to 16 healthy females, with a further 14 receiving a control drink. After 4 h, participants underwent an fMRI scan, during which time CT-innervated forearm skin and CT non-innervated finger skin was stroked with three brushes of differing texture, at CT-optimal force and velocity. Pleasantness ratings were obtained post scanning. The control group showed a greater response in ipsilateral orbitofrontal cortex to CT-activating forearm touch compared to touch to the finger where CTs are absent. This differential response was not present in the tryptophan depleted group. This interaction effect was significant. In addition, control participants showed a differential primary somatosensory cortex response to brush texture applied to the finger, a purely discriminatory touch response, which was not observed in the tryptophan depleted group. This interaction effect was also significant. Pleasantness ratings were similar across treatment groups. These results implicate serotonin in the differentiation between CT-activating and purely discriminatory touch responses. Such effects could contribute to some of the social abnormalities seen in psychiatric disorders associated with abnormal serotonin function. © 2016 Federation of European Neuroscience Societies and John Wiley & Sons Ltd.

    Full Text Available Basic methods are presented to design a simple filter group and a method of shaping the resultant of the filter group’s impedance characteristics (distribution of the characteristics’ extremes and then project equations were transformed into a uniform, common form that addresses issues of the reactive power distribution between component filters. The analysis also takes into account the filters’ detuning from the reduced harmonics and quality factors of passive elements. Another important factor of the analysis considered was the power grid equivalent impedance affecting the filtration effectiveness. A criterion for the filter group’s filtration effectiveness evaluation was proposed and optimisation was completed for the reactive power distribution between separate filters in the function of the power grid’s equivalent inductance.

  16. Power plant siting; an application of the nominal group process technique

    1976-01-01

    The application of interactive group processes to the problem of facility siting is examined by this report. Much of the discussion is abstracted from experience gained in applying the Nominal Group Process Technique, an interactive group technique, to the identification and rating of factors important in siting nuclear power plants. Through this experience, interactive group process techniques are shown to facilitate the incorporation of the many diverse factors which play a role in siting. In direct contrast to mathematical optimization, commonly represented as the ultimate siting technique, the Nominal Group Process Technique described allows the incorporation of social, economic, and environmental factors and the quantification of the relative importance of these factors. The report concludes that the application of interactive group process techniques to planning and resource management will affect the consideration of social, economic, and environmental concerns and ultimately lead to more rational and credible siting decisions

    The objectives of this working group were to provide the ''Future Light Source Community'' information on: Electron-Laser interaction based sources; Plasma based radiation sources and accelerators; and Present and future high-power laser technology. A summary of presentations, discussions and opinions is presented next. At the end of this report, a few references are given. The list is very far from being complete but is meant as a start for further exploring the various topics discussed in this working group. Based on presentations and discussions during the workshop, a summarizing table of the performance of three different types of laser systems has been made. The emphasis is on listing performance parameters of solid state, FEL and gas based lasers, relevant to the development of a future fourth generation light source. Two types of solid state lasers capable of producing peak power in the multi-terawatt range are described: Nd:glass and Ti:sapphire lasers [1]. The main development for these lasers is towards higher average power levels: from the 10 W to the > 100 W level. An infrared FEL has recently produced 1 kW average power but with peak power on the order of 0.1 GW [2]. A terawatt class, short pulse CO 2 based gas laser is under development at the Advanced Test Facility at BNL [3

  19. The Role of Metaphor in Discriminatory Hegemony: The Use of Metaphor in Reporting of Syrians

    2016-12-01

    Full Text Available With the critical approaches in the study of rhetoric as well as critical approaches exhibited in cognitive semantic studies, metaphor has come to be interpreted not only as a means of language, meaning and adornment but also as a way of understanding and describing the World, and as a way of thinking. These studies offer a perspective on how metaphors do and can assume an ideological role in construction and maintenance of hegemonic meanings in the relationship between language, discourse and meaning; and also on how the ideological structure of a discourse can be systematically deciphered using metaphors. Based on the inputs of critical studies, this study aims to problematize the metaphors used to describe asylum seekers, migrants and refugees in newspapers play a role in the construction of discriminatory discourses. Within this scope, this study is based on the analysis of selected news stories regarding the entrance of first large groups of Syrians to Turkey in April 2011; the economic costs of their prolonged stay coupled with the arrival of new refugees especially in 2015; and the death of Ayan Kurdi, a three-year-old toddler who symbolized the ‘death trip’ of refugees on September 2, 2015. Within this framework, the study focuses on the use of metaphors contributing to the production and dissemination of discrimination against refugees through the analysis of news stories in Daily newspapers of Sabah, Posta,Hürriyet, Zaman ve Cumhuriyet,which represent different ideological strains and mind-sets of reporting. In these analyses, the study benefits from the conceptual framework on metaphors developed by Lakoff and Johnson as well as critical discourse analysis method of van Dijk

  6. Individual differences in discriminatory fear learning under conditions of ambiguity: A vulnerability factor for anxiety disorders?

    Directory of Open Access Journals (Sweden)

    Inna eArnaudova

    2013-05-01

    Full Text Available Complex fear learning procedures might be better suited than the common differential fear conditioning paradigm for detecting individual differences related to vulnerability for anxiety disorders. Two such procedures are the blocking procedure and the protection-from-overshadowing procedure. Their comparison allows for the examination of discriminatory fear learning under conditions of ambiguity. The present study examined the role of individual differences in such discriminatory fear learning. We hypothesized that heightened trait anxiety would be related to a deficit in discriminatory fear learning. Participants gave US-expectancy ratings as an index for the threat value of individual CSs following blocking and protection-from-overshadowing training. The difference in threat value at test between the protected-from-overshadowing CS and the blocked CS was negatively correlated with scores on a self-report tension-stress scale that approximates facets of generalized anxiety disorder (DASS-S, but not with other individual difference variables. In addition, a behavioral test showed that only participants scoring high on the DASS-S avoided the protected-from-overshadowing CS. This observed deficit in discriminatory fear learning for participants with high levels of tension-stress might be an underlying mechanism for fear overgeneralization in diffuse anxiety disorders such as generalized anxiety disorder.

    Full Text Available The physicochemical and fatty acid compositions of meat from 81 calves were measured in order to prove whether the extension of suckling period could distinguish “Normal” from “Suprema” class calves. Three groups of animals were investigated depending on their weaning status: NW (animals were milk-fed until seven months, W1 and W2 (animals which were weaned at different ages and reared either in family farms or in feedlot, respectively. There was no difference among animals in relation to the main components (moisture, protein and ash. Significant differences (p<0.05 were found regarding intramuscular fat; the contents were higher in animals weaned at early ages. Color and texture parameters were significantly affected by weaning status. The intramuscular fatty acid composition in the three types of animals showed that saturated fatty acids were the predominant ones in the three groups with values ranging between 48.71% and 49.52% of total methyl esters. Significant differences (p<0.001 were found depending on weaning status in linolenic acid and in the n-6/n-3 ratio, obtaining the highest values in NW animals. Factor analysis method using principal component was applied to the data. The data matrix constructed was subjected to a canonical discriminant analysis in order to classify the NW, W1 and W2 groups. These results showed that 96.6% for the NW group, and 66.7% and 82.4% for W1 and W2 groups respectively, were correctly classified.

  12. Power Distribution System Planning Evaluation by a Fuzzy Multi-Criteria Group Decision Support System

    Directory of Open Access Journals (Sweden)

    Tiefeng Zhang

    2010-10-01

    Full Text Available The evaluation of solutions is an important phase in power distribution system planning (PDSP which allows issues such as quality of supply, cost, social service and environmental implications to be considered and usually involves the judgments of a group of experts. The planning problem is thus suitable for the multi-criteria group decision-making (MCGDM method. The evaluation process and evaluation criteria often involve uncertainties incorporated in quantitative analysis with crisp values and qualitative judgments with linguistic terms; therefore, fuzzy sets techniques are applied in this study. This paper proposes a fuzzy multi-criteria group decision-making (FMCGDM method for PDSP evaluation and applies a fuzzy multi-criteria group decision support system (FMCGDSS to support the evaluation task. We introduce a PDSP evaluation model, which has evaluation criteria within three levels, based on the characteristics of a power distribution system. A case-based example is performed on a test distribution network and demonstrates how all the problems in a PDSP evaluation are addressed using FMCGDSS. The results are acceptable to expert evaluators.

The tasks that give high doses to these work groups were examined and techniques described that were found to be particularly successful in reducing dose. Quantitative information on the extent of radiation doses to various work groups shows that significant numbers of workers in several critical groups receive doses greater than 1 and even 2 rem per year, particularly contract personnel and workers at BWR-type plants. The number of radiation workers whose lifetime dose is greater than their age is much less. Although the techniques presented would go some way in reducing dose, it is likely that a sizeable reduction to the high-dose work groups may require development of new dose-reduction techniques as well as major changes in procedures. 10 refs., 26 tabs

    Negative and discriminatory attitudes towards people living with HIV/AIDS (PLWHA) are one of the biggest experienced challenges by people suffering from HIV, and these attitudes have been regarded as a serious threat to the fundamental rights of all infected people who are affected or associated with this disease in Iran. This study aimed to determine the relationship between public perception about HIV/AIDS and discriminatory attitudes toward PLWHA . The present study was conducted using a descriptive and survey design. Data were collected from 450 patients (236 male and 214 female) in Tehran and Yazd cities. The research instruments were modified HIV-related knowledge/attitude and perception questions about PLWHA, and discriminatory attitudes toward PLWHA. The results showed that prevalence of discriminatory attitudes toward PLWHA in the studied population was 60.0%. There was a significant negative correlation between citizens' awareness about HIV/AIDS, HIV-related attitudes, negative perception toward people with HIV/AIDS symptoms and their discriminatory attitudes toward PLWHA (p AIDS explained for 23.7% of the variance of discriminatory attitudes toward PLWHA. Negative public perceptions about HIV/AIDS in Iran associated with discriminatory attitudes toward PLWHA and cultural beliefs in Iran tend to stigmatize and discriminate against the LWHA.

  16. Growth, institutions and power groups. The forgotten effects in Sinaloa, 1994-2014

    2018-01-01

    Full Text Available Through a non-numerical model, this research identifies the relations of causality revealed by omissions of the power groups that are in charge of political and economic institutions in Sinaloa, and which account for the weak local economic growth. This contribution lies in the use of a methodology that evaluates economic performance based on the subjective assessment of experts’ thinking, who are members of the power elite. For this purpose, postulates of the fuzzy subset theory and the forgotten effects model are introduced. The results suggest that the causes of technological backwardness are a fragile democracy and a weak citizen participation, which reduce growth potential by accumulating degrees of omission. Deficient investment in human capital, technology and research and development leads to insufficient technical progress, educational backwardness, technological stagnation and crime.

    1959-01-01

    The total diffusing power for a crystallite of any form containing a centrosymmetric defect has been established. The antisymmetrical part of the deformation potential only contributes very slightly to the primary dissymmetry. We then go on to study the case of a group of defects of the same type. The calculation converges sufficiently to describe the thermal agitation of an infinite crystal.

    2014-03-01

    Full Text Available In many data envelopment analysis (DEA applications, the analyst always confronts the difficulty that the selected data set is not suitable to apply traditional DEA models for their poor discrimination. This paper presents an approach using Shannon’s entropy to improve the discrimination of traditional DEA models. In this approach, DEA efficiencies are first calculated for all possible variable subsets and analyzed using Shannon’s entropy theory to calculate the degree of the importance of each subset in the performance measurement, then we combine the obtained efficiencies and the degrees of importance to generate a comprehensive efficiency score (CES, which can observably improve the discrimination of traditional DEA models. Finally, the proposed approach has been applied to some data sets from the prior DEA literature.

  1. Concordance and discriminatory power of cough measurement devices for individuals with Parkinson disease.

    2014-05-01

    Dysphagia and aspiration pneumonia are two causes of morbidity in Parkinson disease (PD). In PD, impaired airway clearance can lead to penetration of foreign material, resulting in a high prevalence of aspiration pneumonia and death. This study examines three different devices for measurement of peak airflow during voluntary cough in healthy control subjects and those with PD. Two simple and low-cost devices for measuring peak cough airflow were compared with the "gold standard" pneumotachograph. Thirty-five healthy control subjects and 35 individuals with PD produced voluntary cough at three perceived strengths (weak, moderate, and strong cough) for each of the three devices. A significant difference in mean peak cough airflow was demonstrated for disease (F[1,56] = 4.0, P < .05) and sex (F[1,56] = 9.59, P < .003) across devices. The digital and analog meters were comparable to the gold standard demonstrating no significant difference (statistical) by device (digital vs analog) in receiver operating characteristic curve analysis. Both devices were discriminative of the presence of PD. The analog and digital peak airflow meters are suitable alternatives to the gold standard pneumotachograph due to their low cost, portability, ease of use, and high sensitivity relative to normative peak cough airflows. Voluntary cough airflow measures may serve as a noninvasive means of screening for aspiration risk in target populations. Additionally, quantification of cough strength through use of predetermined limens for weak, moderate, and strong cough may assist clinicians in better describing and tracking cough strength as a contributing factor to aspiration risk.

    Beginning in 1998, the Pacific Northwest National Laboratory (PNL), US Postal Inspection Service Forensic Laboratory (USPIS), and the Data Fusion Laboratory, Drexel University (DFL) have been collaborating on a large scale research project ''Handwriting Individuality--Moving From Art to Science''. In April 1998 a survey was distributed to the community of forensic document examiners (FDEs) requesting input on the habit areas used and their utility in distinguishing handwriting. The information obtained from this survey was intended to provide the data necessary to select the criteria and begin the evaluation of the handwriting samples currently in the project. Preliminary results of the survey were made available to the community at the American Society of Questioned Document Examiners (ASQDE) meeting in August 1998 and the American Academy of Forensic Sciences (AAFS) meeting in February 1999. This report provides final documentation of the survey and its results. This survey has two objectives: (1) to compile a list of handwriting features and characteristics used by professional forensic document examiners in the examination and comparison of handwriting and (2) to gather information about the significance of these features and characteristics. These objectives are met by having the FDEs provide an indication of their experience in the frequency of habit area evaluation and the utility of the habit area for discrimination.

    The aims of this study were (1) to compare water polo game-related statistics by context (winning and losing teams) and sex (men and women), and (2) to identify characteristics discriminating the performances for each sex. The game-related statistics of the 64 matches (44 men's and 20 women's) played in the final phase of the Olympic Games held in Beijing in 2008 were analysed. Unpaired t-tests compared winners and losers and men and women, and confidence intervals and effect sizes of the differences were calculated. The results were subjected to a discriminant analysis to identify the differentiating game-related statistics of the winning and losing teams. The results showed the differences between winning and losing men's teams to be in both defence and offence, whereas in women's teams they were only in offence. In men's games, passing (assists), aggressive play (exclusions), centre position effectiveness (centre shots), and goalkeeper defence (goalkeeper-blocked 5-m shots) predominated, whereas in women's games the play was more dynamic (possessions). The variable that most discriminated performance in men was goalkeeper-blocked shots, and in women shooting effectiveness (shots). These results should help coaches when planning training and competition.

    2012-01-01

    Full Text Available The aim of this study was to establish which final game actions discriminate final victories and defeats in women volleyball formative stages during ended sets, which are solved by regulation with a minimal advantage of two points. A total of 57 sets were analyzed in infantile category and 69 sets in cadet category during the national volleyball championship at school age (12-16, Valladolid 2008 and Huelva 2009. Statistics analysis shows differences between the condition of both the winner and the loser teams in sets in the positive attack in infantile category and in positive block and error in cadet category. Discriminative analysis, statistical test that determines those most significant game actions when establishing the differences existing between the winner and loser teams, shows how to predict victory and defeat in the ended sets regarding the positive attack, negative service and error in infantile category and positive block and error in cadet category. These ones suggest that during decisive set moments in both categories, either technical gestures control or errors which arise from a regulation infraction may predict their final performance.

    We study certain properties of the group J(Z) of substitutions of formal power series in one variable with integer coefficients. We show that J(Z), regarded as a topological group, has four generators and cannot be generated by fewer elements. In particular, we show that the one-dimensional continuous homology of J(Z) is isomorphic to Z oplus Z oplus Z 2 oplus Z 2 . We study various topological and geometric properties of the coset space J(R)/J(Z). We compute the real cohomology H-tilde*(J(Z);R) with uniformly locally constant supports and show that it is naturally isomorphic to the cohomology of the nilpotent part of the Lie algebra of formal vector fields on the line

    2010-09-01

    Throughout human history, leaders have been responsible for helping groups attain important goals. Ideally, leaders use their power to steer groups toward desired outcomes. However, leaders can also use their power in the service of self-interest rather than effective leadership. Five experiments identified factors within both the person and the social context that determine whether leaders wield their power to promote group goals versus self-interest. In most cases, leaders behaved in a manner consistent with group goals. However, when their power was tenuous due to instability within the hierarchy, leaders high (but not low) in dominance motivation prioritized their own power over group goals: They withheld valuable information from the group, excluded a highly skilled group member, and prevented a proficient group member from having any influence over a group task. These self-interested actions were eliminated when the group was competing against a rival outgroup. Findings provide important insight into factors that influence the way leaders navigate the essential tension between leadership and power.

    having nuclear power plants of similar design, and the various technical cooperation activities conducted by international organizations, in particular the IAEA. The first major task for the regulatory body will be carrying out a review of the safety evaluation report of the proposed site for the first nuclear power plant. For this, the regulatory body must lay down the safety requirements that could be developed or adopted from IAEA safety standards on the subject. It will also require a set of specialized competences in areas such as seismology, hydrology, geochemistry and geology that is not necessarily nuclear related. In developing the strategy to secure and maintain a technically competent regulatory body, a decision should be made early whether to recruit staff with those competences or to outsource these activities to agencies where competences in such areas may already be available in the country. Notwithstanding this, the regulatory body still requires a core technical group in the key disciplines to be able to understand and compile the information from the site evaluation reports as input to the site licensing process.

    2013-01-01

    Fusion development has many different challenges in the areas of plasma physics, fusion technologies, materials development and plasma wall interaction. For making fusion power a reality, a coherent approach is necessary, interlinking the different areas of work. To this end, the German fusion program started in 2010 the German DEMO Working Group, bringing together high-level experts from all the different fields, from the 3 German fusion centers Max-Planck-Institut fuer Plasmaphysik (IPP), Karlsruher Institut fuer Technologie (KIT) and Forschungszentrum Juelich (FZJ). An encompassing view of what will be needed with high priority, in plasma physics, in fusion technology and in the interrelation of the fields, to make fusion energy real, has been elaborated, and is presented here in a condensed way. On this basis, the 3 German fusion centers now are composing their work program, towards a fusion demonstration reactor DEMO. (orig.)

    A pragmatic pairwise group-decision approach is applied to compare two regions in order to select the more suitable one for construction of nulcear power plants in the Kingdom of Saudi Arabia. The selection methodology is based on pairwise comparison by forced choice. The method facilitates rating of the regions or sites using simple calculations. Two regions, one close to Dhahran on the Arabian Gulf and another close to Jeddah on the Red Sea, are evaluated. No specific site in either region is considered at this stage. The comparison is based on a set of selection criteria which include (i) topography, (ii) geology, (iii) seismology, (iv) meteorology, (v) oceanography, (vi) hydrology and (vii) proximetry to oil and gas fields. The comparison shows that the Jeddah region is more suitable than the Dhahran region. (orig.)

    2013-01-01

    The prime purpose of this study is to assess HIV/AIDS-related self-stigma and discrimination (S&D) attitudes and associated factors using multivariate analysis of data from the 2010-11 National Survey of Understanding the Root of HIV/AIDS Related Stigma and Discrimination. A national telephone survey was carried out with 2271 of the Malaysian public aged 18-60 years. The sample was contacted by random digit dialing covering the whole of Peninsular Malaysia from December 2010 to May 2011. The HIV-transmission knowledge, HIV-related self-stigma, and public stigma were investigated. Despite high level of HIV-transmission knowledge [mean (SD)=10.56 (2.42), mean score at 70th percentile] the respondents in this study had moderate levels (mean scores near midpoints) of self-stigma and public stigma attitudes. HIV-transmission knowledge score was not significantly correlated with self-stigma score, but showed a significantly small positive effect (r<0.2) for public stigma scores. Ethnicity is the strongest correlate of HIV-transmission knowledge, self-stigma, and public stigma attitudes in the multivariate analyses. Other significant correlates were age, socioeconomic group, and urban-rural setting. The root causes of HIV stigma and discriminatory attitudes were not associated with knowledge deficiency. Interventions should be oriented towards promoting de-stigmatization of HIV/AIDS, and tailored socio-culturally. Copyright © 2013 Elsevier Inc. All rights reserved.

  19. Three experimental approaches to measure the social context dependence of prejudice communication and discriminatory behavior.

    Beyer, Heiko; Liebe, Ulf

    2015-01-01

    Empirical research on discrimination is faced with crucial problems stemming from the specific character of its object of study. In democratic societies the communication of prejudices and other forms of discriminatory behavior is considered socially undesirable and depends on situational factors such as whether a situation is considered private or whether a discriminatory consensus can be assumed. Regular surveys thus can only offer a blurred picture of the phenomenon. But also survey experiments intended to decrease the social desirability bias (SDB) so far failed in systematically implementing situational variables. This paper introduces three experimental approaches to improve the study of discrimination and other topics of social (un-)desirability. First, we argue in favor of cognitive context framing in surveys in order to operationalize the salience of situational norms. Second, factorial surveys offer a way to take situational contexts and substitute behavior into account. And third, choice experiments - a rather new method in sociology - offer a more valid method of measuring behavioral characteristics compared to simple items in surveys. All three approaches - which may be combined - are easy to implement in large-scale surveys. Results of empirical studies demonstrate the fruitfulness of each of these approaches.

    2009-02-01

    As the number of persons living with HIV/AIDS (PLWHA) continues to increase in Puerto Rico, it becomes increasingly important to address the issues of stigma and other discriminatory attitudes. Therefore, the objective of the present study is to examine the attitudes toward PLWHA of a large sample of women living in public housing in Puerto Rico, including sympathy and support for PLWHA in the workplace and in school. A total of 1138 women completed a self-administered 218-item survey made up of questions that measured HIV-related knowledge, attitudes and behaviors. Levels of sympathy varied depending upon the target group, with HIV-infected drug users receiving the least sympathy. Most women reported that HIV-positive teachers should be allowed to teach and that HIV-positive children should be allowed to attend school. However, a significantly lower percentage reported that HIV-infected nurses should be allowed to continue working. Women who were more sympathetic toward PLWHA were more tolerant of PLWHA in the workplace and school, while those with inaccurate knowledge concerning HIV transmission were less tolerant. Also, those who knew a PLWHA were more tolerant. Levels of discriminatory attitudes in Puerto Rico are high and warrant both individual- and societal-level interventions.

    nuclear power plant and the risk of leukaemia in children? There is no official answer to this question, barring that exposure to high doses or to high dose rates increases the risk. Many other genetic and environmental causes must also be taken into consideration, in order to prevent any misunderstanding. The molecular heterogeneity of leukaemia must also be taken into account when interpreting the data. Despite this complexity, the general public needs objective, comprehensible information. Scientists are under the obligation to meet the legitimate expectations of a society that is not only fully aware of its 'right to know', but is also eager for greater humanity and trust. For the reasons listed above, an independent, pluralist, technical working group composed of French and foreign experts with complementary skills and interests was created with the following mandate: - Issue an opinion on the available epidemiological knowledge of the effects of nuclear power plant (NPP), focusing in particular on the risk of childhood leukaemia; - Define the research needed to improve the existing data; - Help to deliver clear, transparent and regular information to the general public.; - Draw up guidelines for improving the existing knowledge on the link between childhood leukaemia and nuclear power plant (especially the impact of very low doses of ionising radiations). These guidelines will be made public. - Present the progress of this work to a national committee tasked with planning and monitoring the measures needed to improve the available knowledge of the effects of discharge from the nuclear industry on the health of people living nearby

    Many studies have focused on the negative effects of discrimination on workers' well-being. However, discrimination does not affect just victims but also those people who witness discriminatory acts or who perceived they are working in a discriminatory work environment. Although perceiving a discriminatory work environment might be a stressor, the presence of job resources might counteract its negative effects, as suggested by the Job Demand-Resources model. The goal of this study is to test the effect of perceiving a discriminatory work environment on workers' psychological well-being when job autonomy and co-workers and supervisor support act as mediator and moderators respectively. To test the moderated mediation model data were gathered with a sample of Italian 114 truckers. Results demonstrated that job autonomy partially mediates the relationship between perceiving a discriminatory work environment and workers' well-being. Main interactional effects have been observed when co-workers support is introduced in the model as moderator, while no main interactional effects exist when supervisor support is introduced. Theoretical and practical implications are discussed.

    Full Text Available Many studies have focused on the negative effects of discrimination on workers’ well-being. However, discrimination does not affect just victims but also those people who witness discriminatory acts or who perceived they are working in a discriminatory work environment. Although perceiving a discriminatory work environment might be a stressor, the presence of job resources might counteract its negative effects, as suggested by the Job Demand-Resources model. The goal of this study is to test the effect of perceiving a discriminatory work environment on workers’ psychological well-being when job autonomy and co-workers and supervisor support act as mediator and moderators respectively. To test the moderated mediation model data were gathered with a sample of Italian 114 truckers. Results demonstrated that job autonomy partially mediates the relationship between perceiving a discriminatory work environment and workers’ well-being. Main interactional effects have been observed when co-workers support is introduced in the model as moderator, while no main interactional effects exist when supervisor support is introduced. Theoretical and practical implications are discussed.

    Elevation of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) is prominent in acute dengue illness. The World Health Organization (WHO) 2009 dengue guidelines defined AST or ALT ≥ 1000 units/liter (U/L) as a criterion for severe dengue. We aimed to assess the clinical relevance and discriminatory value of AST or ALT for dengue hemorrhagic fever (DHF) and severe dengue. We retrospectively studied and classified polymerase chain reaction positive dengue patients from 2006 to 2008 treated at Tan Tock Seng Hospital, Singapore according to WHO 1997 and 2009 criteria for dengue severity. Of 690 dengue patients, 31% had DHF and 24% severe dengue. Elevated AST and ALT occurred in 86% and 46%, respectively. Seven had AST or ALT ≥ 1000 U/L. None had acute liver failure but one patient died. Median AST and ALT values were significantly higher with increasing dengue severity by both WHO 1997 and 2009 criteria. However, they were poorly discriminatory between non-severe and severe dengue (e.g., AST area under the receiver operating characteristic [ROC] curve=0.62; 95% confidence interval [CI]: 0.57-0.67) and between dengue fever (DF) and DHF (AST area under the ROC curve=0.56; 95% CI: 0.52-0.61). There was significant overlap in AST and ALT values among patients with dengue with or without warning signs and severe dengue, and between those with DF and DHF. Although aminotransferase levels increased in conjunction with dengue severity, AST or ALT values did not discriminate between DF and DHF or non-severe and severe dengue.

    In settings of high methicillin-resistant Staphylococcus aureus (MRSA) prevalence, detection of nosocomial transmission events can be difficult without strain typing. Prospective typing of all MRSA isolates could potentially identify transmission in a timely fashion, making infection control responses to outbreaks more effective. We describe the development and evaluation of a novel 19-target binary typing system for MRSA using the multiplex-PCR/reverse line blot hybridization platform. Pulse-field gel electrophoresis (PFGE), spa typing, and phage-derived open reading frame (PDORF) typing were performed for comparison. The system was utilized to identify transmission events in three general surgical wards over a 12-month period. Initial MRSA isolates from 273 patients were differentiated into 55 unique binary types. One or more potential contacts colonized with the same MRSA strain were identified in 69 of 87 cases (79%) in which definite or possible nosocomial MRSA acquisition had occurred. The discriminatory power of the typing system was similar to that of PFGE (Simpson's index of diversity [D] = 0.994, versus 0.987) and higher than that of spa typing (D = 0.926). Strain typing reduced the total number of potential MRSA-colonized source contacts from 859 to 212 and revealed temporal clustering of transmission events. Prospective MRSA typing using this novel binary typing method can rapidly identify nosocomial transmission events, even in high-prevalence settings, which allows timely infection control interventions. The system is rapid, inexpensive, discriminatory, and suitable for routine, high-throughput use in the hospital microbiology laboratory. PMID:22895043

  16. Power and status within small groups: An analysis of students' verbal and nonverbal behavior and responses to one another

    Science.gov (United States)

    Morris, Lynnae Carol

    The purpose of this research has been to determine the influence of verbal and nonverbal behavior on power and status within small groups. The interactions which took place within five small groups of students in a middle school spatial reasoning elective were analyzed. Verbal responses to requests for help were analyzed using sequential analysis techniques. Results indicated that the identity of the student asking a question or requesting help in some form or another is a better predictor of whether he/she will receive help than the type of questions he/she asks. Nonverbal behavior was analyzed for social gestures, body language, and shifts in possession of tools. Each nonverbal act was coded as either "positive" (encouraging participation) or "negative" (discouraging participation); and, the researchers found that in groups in which there was unequal participation and less "help" provided among peers (according to the verbal analysis results) there tended to be more "negative" nonverbal behavior demonstrated than in groups in which "shared talk time" and "helping behavior" were common characteristics of the norm. The combined results from the analyses of the verbal and nonverbal behavior of students within small groups were then reviewed through the conflict, power, status perspective of small group interactions in order to determine some common characteristics of high functioning (collaborative) and low functioning (non-collaborative) groups. Some common characteristics of the higher functioning groups include: few instances of conflict, shared "talk time" and decision making, inclusive leadership, frequent use of encouraging social gestures and body language, and more sharing of tools than seizing. Some shared traits among the lower functioning groups include: frequent occurrences of interpersonal conflict, a focus on process (rather than content), persuasive or alienating leadership, unequal participation and power, frequent use of discouraging social gestures

    Full Text Available Socioeconomic, ethnic and gender disparities in Chronic Obstructive Pulmonary Disease (COPD risk are well established but no studies have applied multilevel analysis of individual heterogeneity and discriminatory accuracy (MAIHDA within an intersectional framework to study this outcome. We study individuals at the first level of analysis and combinations of multiple social and demographic categorizations (i.e., intersectional strata at the second level of analysis. Here we used MAIHDA to assess to what extent individual differences in the propensity of developing COPD are at the intersectional strata level. We also used MAIHDA to determine the degree of similarity in COPD incidence of individuals in the same intersectional stratum. This leads to an improved understanding of risk heterogeneity and of the social dynamics driving socioeconomic and demographic disparities in COPD incidence. Using data from 2,445,501 residents in Sweden aged 45–65, we constructed 96 intersectional strata combining categories of age, gender, income, education, civil- and migration status. The incidences of COPD ranged from 0.02% for young, native males with high income and high education who cohabited to 0.98% for older native females with low income and low education who lived alone. We calculated the intra-class correlation coefficient (ICC that informs on the discriminatory accuracy of the categorizations. In a model that conflated additive and interaction effects, the ICC was good (20.0%. In contrast, in a model that measured only interaction effects, the ICC was poor (1.1% suggesting that most of the observed differences in COPD incidence across strata are due to the main effects of the categories used to construct the intersectional matrix while only a minor share of the differences are attributable to intersectional interactions. We found conclusive interaction effects. The intersectional MAIHDA approach offers improved information to guide public health

    Background Social networking sites, in particular Facebook, are not only predominant in students’ social life but are to varying degrees interwoven with the medical curriculum. Particularly, Facebook groups have been identified for their potential in higher education. However, there is a paucity of data on user types, content, and dynamics of study-related Facebook groups. Objective The aim of this study was to identify the role of study-related Facebook group use, characterize medical students that use or avoid using Facebook groups (demographics, participation pattern, and motivation), and analyze student posting behavior, covered topics, dynamics, and limitations in Facebook groups with regards to educational usage. Methods Using a multi-method approach (interviews, focus groups, and qualitative and quantitative analysis of Facebook posts), we analyzed two representative Facebook groups of medical preclinical semesters at Ludwig-Maximilians-University (LMU) Munich. Facebook primary posts and replies over one semester were extracted and evaluated by using thematic content analysis. We developed and applied a coding scheme for studying the frequency and distribution of these posts. Additionally, we interviewed students with various degrees of involvement in the groups, as well as “new minorities,” students not registered on Facebook. Results Facebook groups seem to have evolved as the main tool for medical students at LMU to complement the curriculum and to discuss study-related content. These Facebook groups are self-organizing and quickly adapt to organizational or subject-related challenges posed by the curriculum. A wide range of topics is covered, with a dominance of organization-related posts (58.35% [6916/11,853] of overall posts). By measuring reply rates and comments per category, we were able to identify learning tips and strategies, material sharing, and course content discussions as the most relevant categories. Rates of adequate replies in these

    Asymptotically safe quantum gravity predicts running gravitational and cosmological constants, while it remains a meaningful quantum field theory because of the existence of a finite number of non-Gaussian ultraviolet fixed points. We have investigated the effect of such running couplings on the cosmological perturbations. We have obtained the improved Mukhanov-Sassaki equation and solved it for two models. The effect of such running of the coupling constants on the cosmological power spectrum is also studied. (orig.)

    A physical-topological model of societal response to the introduction of a technology such as nuclear power is proposed. The formation is based on a conceptual-geometric construct familiar in physics and mathematics. An interesting feature of the model is that it provides for the intrinsic inclusion of such intra-societal conflict manifestations as opinion reversals, opinion polarizations and apparent inconsistencies. The general applicability of this characterization to other societal conflict domains is suggested. (author)

    Depth of anaesthesia monitors usually analyse cerebral function with or without other physiological signals; non-invasive monitoring of the measured cardiorespiratory signals alone would offer a simple, practical alternative. We aimed to investigate whether such signals, analysed with novel, non-linear dynamic methods, would distinguish between the awake and anaesthetised states. We recorded ECG, respiration, skin temperature, pulse and skin conductivity before and during general anaesthesia in 27 subjects in good cardiovascular health, randomly allocated to receive propofol or sevoflurane. Mean values, variability and dynamic interactions were determined. Respiratory rate (p = 0.0002), skin conductivity (p = 0.03) and skin temperature (p = 0.00006) changed with sevoflurane, and skin temperature (p = 0.0005) with propofol. Pulse transit time increased by 17% with sevoflurane (p = 0.02) and 11% with propofol (p = 0.007). Sevoflurane reduced the wavelet energy of heart (p = 0.0004) and respiratory (p = 0.02) rate variability at all frequencies, whereas propofol decreased only the heart rate variability below 0.021 Hz (p cardiorespiratory synchronisation time was increased (p < 0.05). A classification analysis based on an optimal set of discriminatory parameters distinguished with 95% success between the awake and anaesthetised states. We suggest that these results can contribute to the design of new monitors of anaesthetic depth based on cardiovascular signals alone. © 2015 The Authors.

  3. Mentoring overseas nurses: barriers to effective and non-discriminatory mentoring practices.

    2010-09-01

    In this article it is argued that there are barriers to effective and non-discriminatory practice when mentoring overseas nurses within the National Health Service (NHS) and the care home sector. These include a lack of awareness about how cultural differences affect mentoring and learning for overseas nurses during their period of supervised practice prior to registration with the UK Nursing and Midwifery Council. These barriers may demonstrate a lack of effective teaching of ethical practice in the context of cultural diversity in health care. This argument is supported by empirical data from a national study. Interviews were undertaken with 93 overseas nurses and 24 national and 13 local managers and mentors from six research sites involving UK health care employers in the NHS and independent sectors in different regions of the UK. The data collected showed that overseas nurses are discriminated against in their learning by poor mentoring practices; equally, from these data, it appears that mentors are ill-equipped by existing mentor preparation programmes to mentor overseas-trained nurses from culturally diverse backgrounds. Recommendations are made for improving mentoring programmes to address mentors' ability to facilitate learning in a culturally diverse workplace and thereby improve overseas nurses' experiences of their supervised practice.

    Stigma and discriminatory attitudes (SDAs) have a negative impact on human immunodeficiency virus (HIV) prevention, testing, and treatment as well as on family and social networks. There is a lack of understanding about HIV-related SDAs among people living outside large cities. This study is aimed to determine the level of HIV-related SDAs among a semi-urban population in Malaysia and to compare the SDA results among people with different sociodemographic characteristics. A sample of 106 respondents was generated by convenience sampling during the screening campaign in Alor Gajah, Malaysia. Data collection was carried out based on a pre-tested questionnaire via face-to-face interviews. More than half of the respondents (62.3%) thought that an HIV-positive teacher should not be allowed to continue teaching at school; 81.1% were unsure or were unwilling to care for their family member with AIDS at home; 81.2% thought children with HIV/AIDS should not continue to be raised in families; and 77.3% thought they would not reveal if a family member had HIV/AIDS. Priority should be given to evidence-based interventions to reduce HIV-related SDAs. This study did not reveal any significant relationship between sociodemographic profiles and HIV-related SDAs. Therefore, further research with a larger sample size is needed to investigate the underlying causes of HIV-related SDAs.

    Conducting focus groups with adolescents can be challenging given their developmental needs, particularly with sensitive topics. These challenges include intense need for peer approval, declining social trust, short attention span, and reliance on concrete operations thinking. In this article, we describe an adaptation of interactive performance as an alternative to traditional focus group method. We used this method in a study of discrimination experienced by Muslims (ages 13-17) and of peer pressure to engage in sexual behavior experienced by Hispanic girls (ages 10-14). Recommendations for use of this method include using an interdisciplinary team, planning for large amounts of disclosure towards the end of the focus group, and considering the fit of this method to the study topic.

    Full Text Available Chinese patent medicines (CPM, generally prepared from several traditional Chinese medicines (TCMs in accordance with specific process, are the typical delivery form of TCMs in Asia. To date, quality control of CPMs has typically focused on the evaluation of the final products using fingerprint technique and multi-components quantification, but rarely on monitoring the whole preparation process, which was considered to be more important to ensure the quality of CPMs. In this study, a novel and effective strategy labeling "retracing" way based on HPLC fingerprint and chemometric analysis was proposed with Shenkang injection (SKI serving as an example to achieve the quality control of the whole preparation process. The chemical fingerprints were established initially and then analyzed by similarity, principal component analysis (PCA and partial least squares-discriminant analysis (PLS-DA to evaluate the quality and to explore discriminatory components. As a result, the holistic inconsistencies of ninety-three batches of SKIs were identified and five discriminatory components including emodic acid, gallic acid, caffeic acid, chrysophanol-O-glucoside, and p-coumaroyl-O-galloyl-glucose were labeled as the representative targets to explain the retracing strategy. Through analysis of the targets variation in the corresponding semi-products (ninety-three batches, intermediates (thirty-three batches, and the raw materials, successively, the origins of the discriminatory components were determined and some crucial influencing factors were proposed including the raw materials, the coextraction temperature, the sterilizing conditions, and so on. Meanwhile, a reference fingerprint was established and subsequently applied to the guidance of manufacturing. It was suggested that the production process should be standardized by taking the concentration of the discriminatory components as the diagnostic marker to ensure the stable and consistent quality for multi

    Full Text Available Nigeria has an estimated 3.6 million people with HIV/AIDS and is home to one out of every 11 people with HIV/AIDS worldwide. This study is the first population-based assessment of discrimination against people living with HIV/AIDS in the health sector of a country.

The study involved a cross-sectional survey of 1,021 Nigerian health-care professionals (including 324 physicians, 541 nurses, and 133 midwives identified by profession in 111 health-care facilities in four Nigerian states.Fifty-four percent of the health-care professionals (550/1,021 were sampled from public tertiary care facilities. Nine percent of professionals reported refusing to care for an HIV/AIDS patient, and 9% indicated that they had refused an HIV/AIDS patient admission to a hospital. Fifty-nine percent agreed that people with HIV/AIDS should be on a separate ward, and 40% believed a person's HIV status could be determined by his or her appearance. Ninety-one percent agreed that staff and health-care professionals should be informed when a patient is HIV-positive so they can protect themselves. Forty percent believed that health-care professionals with HIV/AIDS should not be allowed to work in any area of health-care that requires patient contact. Twenty percent agreed that many with HIV/AIDS behaved immorally and deserve the disease. Basic materials needed for treatment and prevention of HIV were not adequately available. Twelve percent agreed that treatment of opportunistic infections in HIV/AIDS patients wastes resources, and 8% indicated that treating someone with HIV/AIDS is a waste of precious resources. Providers who reported working in facilities that did not always practice universal precautions were more likely to favor restrictive policies toward people with HIV

    Full Text Available BACKGROUND: Nigeria has an estimated 3.6 million people with HIV/AIDS and is home to one out of every 11 people with HIV/AIDS worldwide. This study is the first population-based assessment of discrimination against people living with HIV/AIDS in the health sector of a country. The purpose of this study was to characterize the nature and extent of discriminatory practices and attitudes in the health sector and indicate possible contributing factors and intervention strategies. The study involved a cross-sectional survey of 1,021 Nigerian health-care professionals (including 324 physicians, 541 nurses, and 133 midwives identified by profession in 111 health-care facilities in four Nigerian states.

    Full Text Available Introduction: Care providers consistently report negative consequences to their mental health as a direct result of their caregiving responsibilities. Specifically, they describe higher levels of distress, mental health problems, and depressive symptoms compared to their non-caregiving matched controls. Powerful Tools for Caregivers (PTC is a national program that aims to empower caregivers to better care for themselves and enhance their self-efficacy. The purpose of the present study was to determine and quantify the effectiveness of the PTC program through pre/post data analysis. Methods: PTC intervention was evaluated at two questionnaire time points: pre-PTC and post-PTC between June 30, 2004 and Oct 16, 2013. Paired sample t-tests (n=409 were conducted using SPSS Statistics Version 22 (IBM Corp., Armonk, NY. Results: PTC increased caregivers who conducted self-care behaviors, who demonstrated self-efficacy, management of depressing emotions and those who used community resources. Conclusion: PTC results in caregivers reporting that they are taking better care of themselves, reacting to their emotions in a healthier manner, gaining more confidence in their caregiving abilities and coping skills, and becoming more knowledgeable about receiving assistance from their community resources.

  13. A discriminatory function for prediction of protein-DNA interactions based on alpha shape modeling.

    Protein-DNA interaction has significant importance in many biological processes. However, the underlying principle of the molecular recognition process is still largely unknown. As more high-resolution 3D structures of protein-DNA complex are becoming available, the surface characteristics of the complex become an important research topic. In our work, we apply an alpha shape model to represent the surface structure of the protein-DNA complex and developed an interface-atom curvature-dependent conditional probability discriminatory function for the prediction of protein-DNA interaction. The interface-atom curvature-dependent formalism captures atomic interaction details better than the atomic distance-based method. The proposed method provides good performance in discriminating the native structures from the docking decoy sets, and outperforms the distance-dependent formalism in terms of the z-score. Computer experiment results show that the curvature-dependent formalism with the optimal parameters can achieve a native z-score of -8.17 in discriminating the native structure from the highest surface-complementarity scored decoy set and a native z-score of -7.38 in discriminating the native structure from the lowest RMSD decoy set. The interface-atom curvature-dependent formalism can also be used to predict apo version of DNA-binding proteins. These results suggest that the interface-atom curvature-dependent formalism has a good prediction capability for protein-DNA interactions.

  14. The Power of Urban Planning on Environmental Sustainability: A Focus Group Study in Finland

    Directory of Open Access Journals (Sweden)

    2014-09-01

    Full Text Available Sustainable communities are promoted as a desirable policy goal and, in particular, local authorities are encouraged to contribute to climate change mitigation through urban planning. Furthermore, recent research takes a broad perspective on the environmental sustainability of urban areas and considers the environmental impact of all consumption. A focus group study was conducted in Finland for the purpose of examining how increased environmental awareness influences urban land use. The 32 participants of three focus groups were professionals of urban planning and environmental sustainability, at both a municipal and a state level. The main finding was that urban planning is viewed as being unable to support environmental sustainability in the broader sense. In general, the participants did not see a connection between urban structure and sustainable lifestyles and only the influence of planning on housing and daily journeys was recognised. Three main reasons for this were identified. Firstly, environmental sustainability in its broader definition is seen as too complex for urban planners to influence alone. Secondly, the dominance of short-term economic issues in decision-making and the lack of co-operation from other stakeholders to achieve environmental aims demotivate land use planners. Thirdly, the prioritisation of urban density may overrule alternative means of promoting environmental sustainability, such as the encouragement of sustainable suburban or non-urban lifestyles.

    The paper summarizes the quality assurance (QA) activities of the Mitsubishi group regarding PWR plant construction. 1. To ensure a uniform approach to QA activities in the group, the Nuclear System Quality Assurance Administration Centre was established at the headquarters of Mitsubishi Heavy Industries. This Centre is engaged in establishing and promoting comprehensive QA plans, in supervising the interface control between the companies concerned, and in auditing each company's QA programme. 2. In parallel with endeavours to complete QA systems, a great effort has been made to instill consciousness of QA in everyone concerned with the work. It is emphasized that quality control (QC) circle activities play an important role in maintaining a high level of quality. An innovative system of design computerization coupled with model engineering is now being developed to improve design reliability and to prevent human error. Reliability improvement and preventive maintenance systems using computers are being introduced with the object of performing systematic corrective actions based on analyses of plant operation.

    Nociceptive testing is a valuable tool in the development of pharmaceutical products, for basic nociceptive research, and for studying changes in pain sensitivity is investigated after inflammatory states or nerve injury. However, in pigs only very limited knowledge about nociceptive processes...... nociceptive stimulation from a computer-controlled CO2-laser beam applied to either the caudal part of the metatarsus on the hind legs or the shoulder region of gilts. In Exp. 1, effects of laser power output (0, 0.5, 1, 1.5 and 2 W) on nociceptive responses toward stimulation on the caudal aspects...... of the metatarsus were examined using 15 gilts kept in one group and tested in individual feeding stalls after feeding. Increasing the power output led to gradually decreasing latency to respond (P 

  19. The utilization of water courses for the production of electric power. Report from a working group

    International Nuclear Information System (INIS)

    1992-01-01

    The problems connected with damming Danish water courses to enable the production of hydroelectricity are discussed. These constraints are generally related to conservation principles and cultural historical interests. It is observed that attempts are usually made to remove dams constructed in water courses such as streams and brooks, in order to ensure the free passage of fish and small animals and it is the opinion of the working group that this policy should continue to be followed. Otherwise alternative methods (such as fish staircases and fish sluices) should be set up to enable the fish to pass through without getting entangled with any turbines. Consideration must be given to the preservation of items of cultural-historical interest. Where waters are stagnant, at least half of the water volume should be left untouched for fish passage, and in other non-stagnant water areas water should be reserved for fish passage. The amount of necessary water volume should be assessed in individual cases. The local authorities have agreed that legislation on dams, the establishment of fauna and fish passages and the dedication of free waters to fish passage should be coordinated. (AB)

    It is presented the absorption-production nodal method for steady and dynamical calculations in one-dimension and one group energy. It was elaborated the NOD1D computer code (in FORTRAN-IV language). Calculations of neutron flux and power distributions, burnup, effective multiplication factors and critical boron concentration were made with the NOD1D code and compared with results obtained through the CITATION code, which uses the finite difference method. The nuclear constants were produced by the LEOPARD code. (M.C.K.) [pt

  2. Critical group doses arising from routine aquatic discharges of activity from the Heysham 2 nuclear power station

    1986-07-01

    An assessment of critical group doses arising from routine discharges of activity to sea from the Heysham 2 nuclear power station has been undertaken using the CODAR2 computer program. The largest critical group dose rate was calculated to be 50 μSv/y, about 80 per cent of which arose from the external exposure of individuals occupying intertidal sediments of the Lune Estuary from the single nuclide 60 Co. CODAR2 employs a single well mixed local compartment for critical group calculations and can not include the effects of processes varying over the compartment. A more detailed study of the critical group exposure has been carried out using recently developed methods to assess the uncertainties and pessimisms involved in the CODAR2 calculations. It is concluded that these calculations are pessimistic by about a factor of 2, with a reference calculation using the more detailed methods giving a dose rate of 23 μSv/y for the Lune Estuary group. Further reductions in the dose estimate might be possible if site specific measurements of the concentration factor for Co on estuarine sediments and the sedimentation rate in the Lune Estuary could be made.

Moreover, this process works best in unstable power hierarchies, which implies that power is treated as a negotiable....... It is thus a central point that power is not necessarily something that breaks down and represses. On the contrary, an explicit focus on the dynamics of power in relation to creativity can be productive for the organisation. Our main focus is to elaborate the implications of this for practice and theory...

  5. Analyzing indirect effects in cluster randomized trials. The effect of estimation method, number of groups and group sizes on accuracy and power.

    Full Text Available Cluster randomized trials assess the effect of an intervention that is carried out at the group or cluster level. Ajzen’s theory of planned behaviour is often used to model the effect of the intervention as an indirect effect mediated in turn by attitude, norms and behavioural intention. Structural equation modelling (SEM is the technique of choice to estimate indirect effects and their significance. However, this is a large sample technique, and its application in a cluster randomized trial assumes a relatively large number of clusters. In practice, the number of clusters in these studies tends to be relatively small, e.g. much less than fifty. This study uses simulation methods to find the lowest number of clusters needed when multilevel SEM is used to estimate the indirect effect. Maximum likelihood estimation is compared to Bayesian analysis, with the central quality criteria being accuracy of the point estimate and the confidence interval. We also investigate the power of the test for the indirect effect. We conclude that Bayes estimation works well with much smaller cluster level sample sizes such as 20 cases than maximum likelihood estimation; although the bias is larger the coverage is much better. When only 5 to 10 clusters are available per treatment condition even with Bayesian estimation problems occur.

  6. Information technology impact on nuclear power plant documentation. Report prepared within the framework of the International Working Group on Nuclear Power Plant Control and Instrumentation

    International Nuclear Information System (INIS)

    2002-04-01

    As the majority of the nuclear power plants (NPPs) in the world were designed and constructed about twenty to forty years ago, these older power plants may have shortcomings in documentation on construction, commissioning, operations, maintenance, or decommissioning. Therefore, facility documentation does not always reflect actual plant status after years of plant operation, modification, and maintenance. To deal with these shortcomings, computer and information technologies that provide sophisticated and modern design tools as well as information processing and storage facilities can offer dramatic innovation from paper-centric documentation towards data-centric documentation. This report addresses all aspects of documentation associated with various life-cycle phases of NPPs and the information technology (IT) that are relevant to the documentation process. It also provides a guide for planning, designing, and executing an IT documentation project. Examples are given to demonstrate successful implementations at plants. Finally, it discusses the issues related to the application of the IT in NPPs and the trends for applications of the IT at NPPs as well as the technology itself. It is recognized that this can also improve configuration management. reliability of data, quality of personnel work, and ultimately plant performance reliability and safety. The aspects of using the IT for NPP documentation are closely related to configuration management at NPPs. The report consists of nine sections, a reference section, and five additional appendices.

    countries having nuclear power plants of similar design, and the various technical cooperation activities conducted by international organizations, in particular the IAEA. The first major task for the regulatory body will be carrying out a review of the safety evaluation report of the proposed site for the first nuclear power plant. For this, the regulatory body must lay down the safety requirements that could be developed or adopted from IAEA safety standards on the subject. It will also require a set of specialized competences in areas such as seismology, hydrology, geochemistry and geology that is not necessarily nuclear related. In developing the strategy to secure and maintain a technically competent regulatory body, a decision should be made early whether to recruit staff with those competences or to outsource these activities to agencies where competences in such areas may already be available in the country. Notwithstanding this, the regulatory body still requires a core technical group in the key disciplines to be able to understand and compile the information from the site evaluation reports as input to the site licensing process

    Full Text Available Research Statement: With an increase in competition within the South African property sector, real estate agencies need to ensure that their channels are as effective as possible. Using the Internet and mobile technologies represents a new means to reach customers and achieve lower operating costs. This study seeks to ascertain which factors potential buyers consider important when perusing residential property in an online environment. Hence, the dimensions of e-service quality, which constitute their online experience, will be explored. In addition, this research explores buyer typologies and probes whether other forms of technology, such as a mobile interface, may be of commercial value to the realtor. Methodology: The empirical analysis was conducted by means of a quantitative survey. A questionnaire was designed to test the application of the e-service quality construct in the South African real-estate sector. Data was obtained from 300 respondents, across the age spectrum, who filled the criteria of being prospective buyers. Convenience sampling was primarily used to collect responses as the researchers were unable to obtain access to a specific database of listed property buyers. Results & Conclusion: As mirrored in other studies of this nature, it was found that trust is paramount when initiating property sales online. All other variables in the construct (site features, information, accessibility, communication, reliability, responsiveness and personalisation also proved significant. A cluster analysis revealed that older respondents preferred a higher level of support - across all attributes of e-service quality - when interacting with online property services. Lastly, the mobile interface appears to appeal to 'students' as well as 'mature workers'. It is surmised that these individuals have access to smart phones capable of being used for accessing property portals. However, the 'young workers' appear less enthusiastic about the mobile interface, seemingly preferring to either access such portals via the Internet or visiting agents personally.

    The New England River Basins Commission/United States Geological Survey-Resource Planning Analysis Office (NERBC/USGS-RPA) Power Plant Siting Task Force has formerly met seven times between July 1979 and August 1980. At the first meeting on July 13, 1979, the members agreed that there were many problems with the current process of selecting sites for power plants in New England, and that they would work by consensus to find solutions for these problems. At the second meeting on October 19, 1979, NERBC staff presented information on the site selection and approval processes in New England. The Task Force began a preliminary discussion of problems in these processes, and agreed that the initial scope of work of the Task Force would focus on issues in site selection. At the third meeting on January 18, 1980, the Task Force began initial discussions in three areas: imperfections in the site selection process, stakeholders in the site selection process, and principles to guide solutions to the problems in site selection. On March 7, 1980, at the fourth meeting, the Task Force continued discussions on imperfections, stakeholders, and principles. At the fifth meeting on May 2, 1980, the Task Force reached a wide range of agreements on the difficulties encountered in the site selection process and on the principles guiding problem solving in site selection. At the sixth meeting on May 29, 1980, the Task Force focused on solutions to the problems identified at earlier meetings. Groups of Task Force members constructed eight different scenarios describing alternative power plant siting processes. In July 1980, the Task Force met for the seventh time and refined the eight scenarios, paring them down to five. An attempt was made to develop two scenarios using the common elements from the five. One of these two graphic models was based on government involvement in the site selection process, and the other was based on stakeholder involvement in the process

    Colors are widely used to warn risk levels and to attract attention of the public. Korea Standard Nuclear Reactor Control Room (KSNRCR) also uses several colors to differentiate warnings, priorities, status, borders, and messages based on the HF010 guideline. However the previous studies showed that the general public not engaged in a specific job domain had different associations of colors as regulated in the standards or the guidelines. It is also expected that the general public not engaged in nuclear power plant industry will have different color association system from the color coding system applied to the KSNRCR. So, this study was performed to show whether there is any difference between color association of a sample Korean group and the color meanings specified in the HF010 guideline. The general public not engaged in the nuclear power plant industry have no idea of the color usage in the nuclear control room. So we converted the specific color usage situation into similar but general situations. In questionnaire, we gave subjects the general situation where color coding is appled and alternative colors which were applied to the HF010 guidelines. And we asked the subjects to choose the colors proper to the situation and to rank the colors according to the degree of suitability. A hundred college students participated in the experiment. 10 refs., 7 tabs. (Author)

    McMunn, et al. v Babcock and Wilcox Power Generation Group, Inc., et al. was one of 17 related public liability actions filed between 2010 and 2015 by individuals living and/or working in the vicinity of two former fuel fabrication facilities who alleged that releases of radioactive materials from those facilities contaminated the air, soil, surface water and groundwater in the surrounding communities, causing them personal injury and property damage. The plaintiffs in all 17 cases claimed they had contracted various cancers and their property was contaminated with uranium. Plaintiffs brought their claims pursuant to the Price-Anderson Amendments Act (PAA) and the Atomic Energy Act of 1954, as amended (AEA), and also asserted related state law claims of negligence, negligence per se, strict liability, civil conspiracy, and wrongful death and survival. The defendants, Babcock and Wilcox Power Generation Group, Inc., B and W Technical Services, Inc. and Atlantic Richfield Company (ARCO), were unrelated companies who, at different times, owned and operated those facilities. The PAA, which became law on 2 September 1957, is a federal statute that governs claims for personal injury and property damage 'arising from the activities of NRC licensees and DOE contractors'. These claims are defined in the PAA as public liability actions. In order to prevail in a public liability action, plaintiffs must establish through expert evidence that the defendants released radiation into the environment in excess of the limits then permitted by federal regulations and that the plaintiffs were exposed to those releases. They must also establish that their respective exposures to radionuclides were capable of causing their illnesses and that the doses of radiation they received did in fact cause their illnesses

    An extensive body of literature exists on the obstacles that have to be overcome in green power retailing. In this article, target group-specific marketing is evaluated as a strategy to increase the share of residential customers of green power. A sample of students in the city of Freiburg, Germany was interviewed in order to assess their awareness of environmental issues, their willingness to change to green power products, and to better understand individual hindrances in changing the power supplier. The analysis shows that students are highly positive towards green power products, but for several reasons difficult to reach in marketing campaigns. Aspects to be considered in addressing this consumer-group include the students' particular expectations towards green products, their living-conditions, price sensitivity, and their perception of the relative effort involved in changing the power provider.

  16. Management of operational safety in nuclear power plants. INSAG-13. A report by the International Nuclear Safety Advisory Group

    International Nuclear Information System (INIS)

    1999-01-01

    The International Atomic Energy Agency's activities relating to nuclear safety are based upon a number of premises. First and foremost, each Member State bears full responsibility for the safety of its nuclear facilities. States can be advised, but they cannot be relieved of this responsibility. Secondly, much can be gained by exchanging experience; lessons learned can prevent accidents. Finally, the image of nuclear safety is international; a serious accident anywhere affects the public's view of nuclear power everywhere. With the intention of strengthening its contribution to ensuring the safety of nuclear power plants, the IAEA established the International Nuclear Safety Advisory Group (INSAG), whose duties include serving as a forum for the exchange of information on nuclear safety issues of international significance and formulating, where possible, commonly shared safety principles. Engineering issues have received close attention from the nuclear community over many years. However, it is only in the last decade or so that organizational and cultural issues have been identified as vital to achieving safe operation. INSAG's publication No. 4 has been widely recognized as a milestone in advancing thinking about safety culture in the nuclear community and more widely. The present report deals with the framework for safety management that is necessary in organizations in order to promote safety culture. It deals with the general principles underlying the management of operational safety in a systematic way and provides guidance on good practices. It also draws on the results of audits and reviews to highlight how shortfalls in safety management have led to incidents at nuclear power plants. In addition, several specific issues are raised which are particularly topical in view of organizational changes that are taking place in the nuclear industry in various countries. Advice is given on how safety can be managed during organizational change, how safety

    Maternal psychopathology and traumatic life experiences may adversely impact family functioning, the quality of the parent-child relationship and the attachment bond, placing the child's early social-emotional development at risk. Attachment-based parenting interventions may be particularly useful in decreasing negative outcomes for children exposed to risk contexts, yet high risk families frequently do not engage in programs to address mental health and/or parenting needs. This study evaluated the effects of Mom Power (MP), a 13-session parenting and self-care skills group program for high-risk mothers and their young children (age parenting competence, and engagement in treatment. Mothers were referred from community health providers for a phase 1 trial to assess feasibility, acceptability, and pilot outcomes. At baseline, many reported several identified risk factors, including trauma exposure, psychopathology, poverty, and single parenthood. Ninety-nine mother-child pairs were initially recruited into the MP program with 68 women completing and providing pre- and post-self-report measures assessing demographics and trauma history (pre-assessment only), maternal mental health (depression and post-traumatic stress disorder (PTSD)), parenting, and intervention satisfaction. Results indicate that MP participation was associated with reduction in depression, PTSD, and caregiving helplessness. A dose response relationship was evident in that, despite baseline equivalence, women who attended ≥70 % of the 10 groups (completers; N = 68) improved on parenting and mental health outcomes, in contrast to non-completers (N = 12). Effects were most pronounced for women with a mental health diagnosis at baseline. The intervention was perceived as helpful and user-friendly. Results indicate that MP is feasible, acceptable, and holds promise for improving maternal mental health and parenting competence among high-risk dyads. Further research is warranted to evaluate

    This study evaluates potential markers in blood and stools for their ability to distinguish bacterial from viral gastroenteritis. A total of 108 patients were prospectively recruited, of which 27 showed bacterial, 30 viral, and 51 no detectable pathogen, respectively. Cytokines, C-reactive protein (CRP), and white blood cells as well as the 2 fecal markers lactoferrin and calprotectin were determined. Statistics comprised Kruskal-Wallis test and U test in addition to an assessment of receiver operating characteristic. Interferon γ (IFNγ) levels were significantly increased in the viral group compared to the bacterial and nonspecific group. For the bacterial group, both fecal markers lactoferrin and calprotectin as well as CRP were significantly higher in comparison to the other 2 groups. To differentiate between bacterial and viral gastroenteritis, CRP, serum IFNγ, and the fecal proteins lactoferrin and calprotectin may be useful. A corresponding algorithm should be evaluated prospectively. Copyright © 2013 Elsevier Inc. All rights reserved.

    In intractable intergroup conflicts, groups often try to frame intergroup violence as legitimate through the use of emotional appeals. Two experiments demonstrate that outsiders' perception of which emotion conflict parties communicate influences the extent to which they legitimize their violence.

    Exposure-outcome studies, for instance on work-related low-back pain (LBP), often classify workers into groups for which exposures are estimated from measurements on a sample of workers within or outside the specific study. The present study investigated the influence on bias and power in exposure-outcome associations of the sizes of the total study population and the sample used to estimate exposures. At baseline, lifting, trunk flexion, and trunk rotation were observed for 371 of 1131 workers allocated to 19 a-priori defined occupational groups. LBP (dichotomous) was reported by all workers during 3 years of follow-up. All three exposures were associated with LBP in this parent study (P power (P power >0.80 (P level = 0.05). A similar performance required n ≥ 30 workers for rotated trunk. Small numbers of observed workers (k) resulted in biased OR, while power was, in general, more sensitive to the total number of workers (n). In epidemiologic studies using a group-based exposure assessment strategy, statistical performance may be sufficient if outcome is obtained from a reasonably large number of workers, even if exposure is estimated from only few workers per group. © The Author 2014.

    Modapothala, J. R.; Issac, B.; Jayamani, E.

    The voluntary disclosure of the sustainability reports by the companies attracts wider stakeholder groups. Diversity in these reports poses challenge to the users of information and regulators. This study appraises the corporate sustainability reports as per GRI (Global Reporting Initiative) guidelines (the most widely accepted and used) across all industrial sectors. Text mining is adopted to carry out the initial analysis with a large sample size of 2650 reports. Statistical analyses were performed for further investigation. The results indicate that the disclosures made by the companies differ across the industrial sectors. Multivariate Discriminant Analysis (MDA) shows that the environmental variable is a greater significant contributing factor towards explanation of sustainability report.

    The purpose of this article is to assess the diagnostic performance of quantitative shear wave elastography in the evaluation of solid breast masses and to determine the most discriminatory parameter. B-mode ultrasound and shear wave elastography were performed before core biopsy of 123 masses in 112 women. The diagnostic performance of ultrasound and quantitative shear wave elastography parameters (mean elasticity, maximum elasticity, and elasticity ratio) were compared. The added effect of shear wave elastography on the performance of ultrasound was determined. The mean elasticity, maximum elasticity, and elasticity ratio were 24.8 kPa, 30.3 kPa, and 1.90, respectively, for 79 benign masses and 130.7 kPa, 154.9 kPa, and 11.52, respectively, for 44 malignant masses (p shear wave elastography parameter was higher than that of ultrasound (p shear wave elastography parameters to the evaluation of BI-RADS category 4a masses, about 90% of masses could be downgraded to BI-RADS category 3. The numbers of downgraded masses were 40 of 44 (91%) for mean elasticity, 39 of 44 (89%) for maximum elasticity, and 42 of 44 (95%) for elasticity ratio. The numbers of correctly downgraded masses were 39 of 40 (98%) for mean elasticity, 38 of 39 (97%) for maximum elasticity, and 41 of 42 (98%) for elasticity ratio. There was improvement in the diagnostic performance of ultrasound of mass assessment with shear wave elastography parameters added to BI-RADS category 4a masses compared with ultrasound alone. Combined ultrasound and elasticity ratio had the highest improvement, from 35.44% to 87.34% for specificity, from 45.74% to 80.77% for positive predictive value, and from 57.72% to 90.24% for accuracy (p shear wave elastography parameters of benign and malignant solid breast masses. By adding shear wave elastography parameters to BI-RADS category 4a masses, we found that about 90% of them could be correctly downgraded to BI-RADS category 3, thereby avoiding biopsy.

    Confirmatory factor analyses of data (from five samples: N = 308 accountants and finance professionals, N = 578 management and non-management employees, and N = 588 employed management students in the U.S.; N = 728 management and non-management employees in S. Korea, N = 250 management and non-management bank employees in Bangladesh) on the 29 items of the Rahim Leader Power Inventory were performed with LISREL 7. The results provided support for the convergent and discriminant validities of the subscales measuring the five bases of leader power (coercive, reward, legitimate, expert, and referent), and the invariance of factor pattern and factor loadings across organizational levels and the three American samples. Additional analysis indicated that leader power profiles differed across the three national cultures represented in the study.

  14. Comprehensive Evaluation of the Sustainable Development of Power Grid Enterprises Based on the Model of Fuzzy Group Ideal Point Method and Combination Weighting Method with Improved Group Order Relation Method and Entropy Weight Method

    Full Text Available As an important implementing body of the national energy strategy, grid enterprises bear the important responsibility of optimizing the allocation of energy resources and serving the economic and social development, and their levels of sustainable development have a direct impact on the national economy and social life. In this paper, the model of fuzzy group ideal point method and combination weighting method with improved group order relation method and entropy weight method is proposed to evaluate the sustainable development of power grid enterprises. Firstly, on the basis of consulting a large amount of literature, the important criteria of the comprehensive evaluation of the sustainable development of power grid enterprises are preliminarily selected. The opinions of the industry experts are consulted and fed back for many rounds through the Delphi method and the evaluation criteria system for sustainable development of power grid enterprises is determined, then doing the consistent and non dimensional processing of the evaluation criteria. After that, based on the basic order relation method, the weights of each expert judgment matrix are synthesized to construct the compound matter elements. By using matter element analysis, the subjective weights of the criteria are obtained. And entropy weight method is used to determine the objective weights of the preprocessed criteria. Then, combining the subjective and objective information with the combination weighting method based on the subjective and objective weighted attribute value consistency, a more comprehensive, reasonable and accurate combination weight is calculated. Finally, based on the traditional TOPSIS method, the triangular fuzzy numbers are introduced to better realize the scientific processing of the data information which is difficult to quantify, and the queuing indication value of each object and the ranking result are obtained. A numerical example is taken to prove that the

    Weight-loss programmes for adults with type 2 diabetes are less effective in the long term owing to regain of weight. Our aim was to determine the 2 year effectiveness of a cognitive behavioural group therapy (group-CBT) programme in weight maintenance after diet-induced weight loss in overweight and obese adults with type 2 diabetes, using a randomised, parallel, non-blinded, pragmatic study design. We included 158 obese adults (median BMI 36.3 [IQR 32.5-40.0] kg/m 2 ) with type 2 diabetes from the outpatient diabetes clinic of Erasmus MC, the Netherlands, who achieved ≥5% weight loss on an 8 week very low calorie diet. Participants were randomised (stratified by weight loss) to usual care or usual care plus group-CBT (17 group sessions). The primary outcomes were the between-group differences after 2 years in: (1) body weight; and (2) weight regain. Secondary outcomes were HbA 1c levels, insulin dose, plasma lipid levels, depression, anxiety, self-esteem, quality of life, fatigue, physical activity, eating disorders and related cognitions. Data were analysed using linear mixed modelling. During the initial 8 week dieting phase, the control group (n = 75) lost a mean of 10.0 (95% CI 9.1, 10.9) kg and the intervention group (n = 83) lost 9.2 (95% CI 8.4, 10.0) kg (p = 0.206 for the between-group difference). During 2 years of follow-up, mean weight regain was 4.7 (95% CI 3.0, 6.3) kg for the control group and 4.0 (95% CI 2.3, 5.6) kg for the intervention group, with a between-group difference of -0.7 (95% CI -3.1, 1.6) kg (p = 0.6). The mean difference in body weight at 2 years was -1.2 (95% CI -7.7, 5.3) kg (p = 0.7). None of the secondary outcomes differed between the two groups. Despite increased treatment contact, a group-CBT programme for long-term weight maintenance after an initial ≥5% weight loss from dieting in obese individuals with type 2 diabetes was not superior to usual care alone.

    Matrix-assisted laser desorption/ionization, time-of-flight mass spectrometry (MALDI-TOF MS), is a sensitive analytical method capable of resolving DNA fragments varying in mass by a single nucleotide. MALDI-TOF MS is applicable to blood group genotyping, as the majority of blood group antigens are encoded by single nucleotide polymorphisms. Blood group genotyping by MALDI-TOF MS can be performed using a panel (Hemo ID Blood Group Genotyping Panel, Agena Bioscience Inc., San Diego, CA) that is a set of genotyping assays that predict the phenotype for 101 antigens from 16 blood group systems. These assays involve three fundamental stages: multiplex target-specific polymerase chain reaction amplification, allele-specific single base primer extension, and MALDI-TOFMS analysis using the MassARRAY system. MALDI-TOF MS-based genotyping has many advantages over alternative methods including high throughput, high multiplex capability, flexibility and adaptability, and the high level of accuracy based on the direct detection method. Currently available platforms for MALDI-TOF MS-based genotyping are not without limitations, including high upfront instrumentation costs and the number of non-automated steps. The Hemo ID Blood Group Genotyping Panel, developed and optimized in a collaboration between the vendor and the Blood Transfusion Service of the Swiss Red Cross in Zurich, Switzerland, is not yet widely utilized, although several laboratories are currently evaluating the MassARRAY system for blood group genotyping. Based on the accuracy and other advantages offered by MALDITOF MS analysis, in the future, this method is likely to become widely adopted for blood group genotyping, in particular, for population screening.

    The global literature has revealed a potential negative impact of social stigma on both physical and mental health among stigmatized individuals; however, the mechanisms through which social stigma affects the individual's quality of life and mental health are not well understood. This research simultaneously examines the relationships of several determinants and mediating factors of psychological distress and quality of life. Data were collected through a cross-sectional survey among 1006 adult (predominantly male) rural-to-urban migrants in 2004-2005 in Beijing, China. Participants reported on their perceived social stigma, discriminatory experiences in daily life, preparation for migration, discrepancy between expectation and reality, coping with stigma-related stress, psychological distress, and quality of life. Structural equation modeling was performed. We found that perceived social stigma and discriminatory experiences had direct negative effects on psychological distress and quality of life among rural-to-urban migrants. Expectation-reality discrepancy mediated the effects of perceived social stigma and discriminatory experiences on psychological distress and quality of life; coping mediated the effect of social stigma on quality of life. Psychological distress was associated with quality of life. Preparation prior to migration was positively related to coping skills, which were positively related to quality of life. We conclude that perceived social stigma and daily discriminatory experiences have a significant influence on psychological distress and quality of life among rural-to-urban migrants. Pre-migration training with a focus on establishment of effective coping skills and preparation of migration may be helpful to improve their quality of life and mental health.

    1976-01-01

    The major air pollutants released from conventional power plants have been found to be sulfur dioxide (SO 2 ), nitrogen oxides (NOx) and suspended particulates beside these three major pollutants other substances (CO, O 3 , hydrocarbons, vanadium...) occur in air or in water. Origin and extent of these pollutants as well as their main health hazards, especially for the respiratory system, have been evaluated. Other risks connected with the whole fuel cycle (coal extraction, petrol refining...) have been considered to be significant for human health. A mathematical model has been set up by the C.E.N. of Mol (Belgium) in order to predict the content of pollutants at the soil level, especially for SO 2 . A relationship between SO 2 content and the concentration of the other pollutants has been found by assuming certain hypothesis. Epidemiological and toxicological data connected with the SO 2 release have been given. As for nonradioactive pollutants released from nuclear power plants their amount has been considered to be negligible. (G.C.)

    A set of 711 samples from four U.S. population groups was analyzed using a novel mass spectrometry based method for mitochondrial DNA (mtDNA) base composition profiling. Comparison of the mass spectrometry results with Sanger sequencing derived data yielded a concordance rate of 99.97%. Length heteroplasmy was identified in 46% of samples and point heteroplasmy was observed in 6.6% of samples in the combined mass spectral and Sanger data set. Using discrimination capacity as a metric, Sanger sequencing of the full control region had the highest discriminatory power, followed by the mass spectrometry base composition method, which was more discriminating than Sanger sequencing of just the hypervariable regions. This trend is in agreement with the number of nucleotides covered by each of the three assays. Published by Elsevier Ireland Ltd.

    Hydrologic models are developed, tested, and refined based on the ability of those models to explain available hydrologic data. The optimization of model performance based upon mismatch between model outputs and real world observations has been extensively studied. However, identification of plausible models is sensitive not only to the models themselves - including model structure and model parameters - but also to the location, timing, type, and number of observations used in model calibration. Therefore, careful selection of hydrologic observations has the potential to significantly improve the performance of hydrologic models. In this research, we seek to reduce prediction uncertainty through optimization of the data collection process. A new tool - multiple model analysis with discriminatory data collection (MMA-DDC) - was developed to address this challenge. In this approach, multiple hydrologic models are developed and treated as competing hypotheses. Potential new data are then evaluated on their ability to discriminate between competing hypotheses. MMA-DDC is well-suited for use in recursive mode, in which new observations are continuously used in the optimization of subsequent observations. This new approach was applied to a synthetic solute transport experiment, in which ranges of parameter values constitute the multiple hydrologic models, and model predictions are calculated using likelihood-weighted model averaging. MMA-DDC was used to determine the optimal location, timing, number, and type of new observations. From comparison with an exhaustive search of all possible observation sequences, we find that MMA-DDC consistently selects observations which lead to the highest reduction in model prediction uncertainty. We conclude that using MMA-DDC to evaluate potential observations may significantly improve the performance of hydrologic models while reducing the cost associated with collecting new data.

    In recent years, interest for the development of micro hydro-electric power plants have been on the increase. There are many and often varying public interests associated with energy development. We have particularly examined the main arguments that are used and what values seem to be based on prevailing attitudes and opinions. Our selected study sites are three municipalities with a relatively extensive small hydro power development: Foerde, Sogn and Fjordane, Hordaland and Kvinnherad Sirdal in Vest-Agder. We have used qualitative methods through semi-structured interviews and discussions in groups, so-called focus groups. Focus groups create an interaction between group participants that can bring out more information than by interviewing each participant individually. Qualitative methods are used to capture the phenomena and assessments that are difficult to quantify or measure, such as people's views and assessments. Our data is not documented facts, but 'assessments of reality.' We had two focus groups in each municipality, a group with representatives from interested organizations in conservation, outdoor recreation, or personal scientific expertise / interest (referred to as environmental groups), and one with representatives from landowners, developers, and other economic interests (called Business Groups). For many of the topics we touched upon such varied viewpoints fairly systematically between our two groups. Business groups see great economic opportunities for both local communities and landowners, arguing that while the development of small hydro power is a very important environmental measure because it allows renewable energy without adverse climate effects and will replace the climate damaging coal in Europe. Environmental groups argue that the new small hydro energy produces no net greenhouse benefit because it only comes on top of polluting coal power, it replaces it. They think it is important to question the environmental impact

    1996-01-01

    The report attempts to address a very wide range of circumstances from, old plant operating at very low powers that face major ageing issues, to new potentially high performance plant for which it has been decided I and C improvements are required to resolve safety issues. The process of change raises many issues as to what potentially might be achieved by such a change to overcome obsolescence, economic and safety problems. The report must also include appropriate consideration of the increasingly international nature of the instrumentation and control system supply industry. Consequently, it does not ignore the different national approaches that are used to demonstrate the systems are suitable to be brought into service. The report does not seek to provide advice on how the different national licensing processes should be approached

    The nature of the effects of the low-doses from ionizing radiation has been the subject of considerable interest in the scientific community. The deleterious health effects caused by the relatively high doses of radiation led to the belief that radiation was harmful at all doses. Afterwards, the concept of the threshold dose explained that negative health effects were observed only at certain dose levels. Furthermore, it has been suggested that low doses of ionizing radiation might have beneficial effects on organisms leading to an hermetic effect of these low doses. The specific objectives of the study were to compute the morbidity (prevalence) of cancer among the radiation occupational workers and their families and to compare with suitable controls and to study prevalence of congenital anomalies among the offspring of the employees of the nuclear power plants in India and to determine, if any, their causal relation with radiation exposure

    Diffusion tensor imaging (DTI) is a promising approach for investigating the white matter microstructure of the spinal cord. However, it suffers from severe susceptibility, physiological, and instrumental artifacts present in the cord. Retrospective correction techniques are popular approaches to reduce these artifacts, because they are widely applicable and do not increase scan time. In this paper, we present a novel outlier rejection approach (reliability masking) which is designed to supplement existing correction approaches by excluding irreversibly corrupted and thus unreliable data points from the DTI index maps. Then, we investigate how chains of retrospective correction techniques including (i) registration, (ii) registration and robust fitting, and (iii) registration, robust fitting, and reliability masking affect the statistical power of a previously reported finding of lower fractional anisotropy values in the posterior column and lateral corticospinal tracts in cervical spondylotic myelopathy (CSM) patients. While established post-processing steps had small effect on the statistical power of the clinical finding (slice-wise registration: -0.5%, robust fitting: +0.6%), adding reliability masking to the post-processing chain increased it by 4.7%. Interestingly, reliability masking and registration affected the t-score metric differently: while the gain in statistical power due to reliability masking was mainly driven by decreased variability in both groups, registration slightly increased variability. In conclusion, reliability masking is particularly attractive for neuroscience and clinical research studies, as it increases statistical power by reducing group variability and thus provides a cost-efficient alternative to increasing the group size.

  11. Safe management of the operating lifetimes of nuclear power plants. INSAG-14. A report by the International Nuclear Safety Advisory Group

    International Nuclear Information System (INIS)

    2014-01-01

    The International Atomic Energy Agency's activities relating to nuclear safety are based upon a number of premises. First and foremost, each Member State bears full responsibility for the safety of its nuclear facilities. States can be advised, but they cannot be relieved of this responsibility. Secondly, much can be gained by exchanging experience; lessons learned can prevent accidents. Finally, the image of nuclear safety is international; a serious accident anywhere affects the public's view of nuclear power everywhere. With the intention of strengthening its contribution to ensuring the safety of nuclear power plants, the IAEA established the International Nuclear Safety Advisory Group (INSAG), whose duties include serving as a forum for the exchange of information on nuclear safety issues of international significance and formulating, where possible, commonly shared safety principles. The present report by INSAG deals with a general approach to the safe management of the operating lifetimes of nuclear power plants. It responds to the concerns about maintaining adequate safety levels at ageing plants, even beyond their design lifetimes. Maintaining adequate safety levels implies first and foremost stringent control of equipment ageing, consistent with the design safety bases of the plants. However, as stated in the 75-INSAG-3 report, 'Basic Safety Principles for Nuclear Power Plants', nuclear safety requires a continuing quest for excellence; this implies enhancinuest for excellence; this implies enhancing the safety levels of operating nuclear power plants as far as reasonably practicable, with due account taken of experience and advancement in knowledge. Moreover, in view of the present situation of the nuclear industry, it may become difficult to maintain adequate competences in many countries with nuclear power programmes. These topics are considered in this latest INSAG report and released to a wider audience

    International Nuclear Information System (INIS)

    1996-01-01

    After a background information on the mandate of the task group and its organisation, the longevity of nuclear power plants is first addressed: the present status of nuclear power plants in the 25 OECD Member Countries is summarised and the importance of ensuring continued safe operation of nuclear power plants described. Safety-related concrete structures (primarily containments) for several reactor concepts are briefly described as well as their materials of construction. Primary mechanisms that can produce adverse ageing of the concrete structures are described (e.g., chemical attack and corrosion of steel reinforcement). The overall performance of nuclear power plant concrete structures is described and age-related degradation incidences that have occurred are noted (e.g., corrosion of steel in water intake structures and corrosion of metal liners). National ageing management programmes of OECD Member Countries are then described with the emphasis placed on nuclear power plant safety-related concrete structures. Although the majority of these programmes are addressing components such as the reactor pressure vessel and steam generator, several national programmes have sophisticated activities that address the concrete structures (e.g., Canada, France, Japan, Switzerland, United Kingdom, and the United States). International ageing management activities are then summarised, primarily addressed under the auspices of the International Atomic Energy Agency (IAEA) (ageing management activities for concrete containment buildings) and the Commission of European Communities (CEC) (assessment of the long-term durability of reinforced and prestressed concrete structures and buildings, and steel containments in nuclear power plants). General conclusions and recommendations are provided at the end of the report

    Prediction of Alzheimers disease (AD) progression based on baseline measures allows us to understand disease progression and has implications in decisions concerning treatment strategy. To this end we combine a predictive multi-task machine learning method 1 with novel MR-based multivariate morphometric surface map of the hippocampus 2 to predict future cognitive scores of patients. Previous work by Zhou et al. 1 has shown that a multi-task learning framework that performs prediction of all future time points (or tasks) simultaneously can be used to encode both sparsity as well as temporal smoothness. They showed that this can be used in predicting cognitive outcomes of Alzheimers Disease Neuroimaging Initiative (ADNI) subjects based on FreeSurfer-based baseline MRI features, MMSE score demographic information and ApoE status. Whilst volumetric information may hold generalized information on brain status, we hypothesized that hippocampus specific information may be more useful in predictive modeling of AD. To this end, we applied Shi et al. 2 s recently developed multivariate tensor-based (mTBM) parametric surface analysis method to extract features from the hippocampal surface. We show that by combining the power of the multi-task framework with the sensitivity of mTBM features of the hippocampus surface, we are able to improve significantly improve predictive performance of ADAS cognitive scores 6, 12, 24, 36 and 48 months from baseline.

    We study the contribution of environmental groups to new technology adoption and diffusion by dominant incumbents. Building on institutional and social movement theory, we develop a theoretical framework that sheds light on environmental groups as change-actors. We theorize that by approaching embedded key constituents with various strategic actions, environmental groups affect taken-for-granted beliefs, build legitimacy for renewable energy technologies, and convince skeptical constituents to support the new technology. We verify our theoretical framework with a case study of wind power development in Colorado. We find that environmentalists educate constituents on the benefits of the new technology, engage in activities leading to regulatory and legislative decisions for wind, while also providing direct assistance to the utility. As a result, utilities are both pressured and encouraged to adopt and diffuse wind power on a large-scale. This research directs attention to the role of environmental groups as change-actors and the legitimating effects of their actions. It highlights their part in creating a more favorable institutional environment for new technologies while directly influencing the incumbent's technology choice. This paper contributes to an understanding of bottom-up, actor-initiated changes in energy systems taking into account both the systemic technological infrastructure and the institutional context. - Highlights: • We study environmentalists′ impact on utility-scale renewable technology diffusion. • Incumbent-dominated systems hinder the diffusion of new technologies. • Environmental groups′ strategic actions increase legitimacy for new technologies. • Environmental groups′ legitimating actions affect incumbent′s technology choice. • Environmental groups create a favorable institutional context for new technologies

  18. Group method of data handling and neral networks applied in monitoring and fault detection in sensors in nuclear power plants

    Bueno, Elaine Inacio

    2011-01-01

    The increasing demand in the complexity, efficiency and reliability in modern industrial systems stimulated studies on control theory applied to the development of Monitoring and Fault Detection system. In this work a new Monitoring and Fault Detection methodology was developed using GMDH (Group Method of Data Handling) algorithm and Artificial Neural Networks (ANNs) which was applied to the IEA-R1 research reactor at IPEN. The Monitoring and Fault Detection system was developed in two parts: the first was dedicated to preprocess information, using GMDH algorithm; and the second part to the process information using ANNs. The GMDH algorithm was used in two different ways: firstly, the GMDH algorithm was used to generate a better database estimated, called matrix z , which was used to train the ANNs. After that, the GMDH was used to study the best set of variables to be used to train the ANNs, resulting in a best monitoring variable estimative. The methodology was developed and tested using five different models: one Theoretical Model and four Models using different sets of reactor variables. After an exhausting study dedicated to the sensors Monitoring, the Fault Detection in sensors was developed by simulating faults in the sensors database using values of 5%, 10%, 15% and 20% in these sensors database. The results obtained using GMDH algorithm in the choice of the best input variables to the ANNs were better than that using only ANNs, thus making possible the use of these methods in the implementation of a new Monitoring and Fault Detection methodology applied in sensors.

  19. Ideology, interest-group formation, and protest: the case of the anti-nuclear power movement, the Clamshell Alliance, and the New Left

    The thesis analyzes the development of the Clamshell Alliance, the first and most successful anti-nuclear power protest group. The key question the dissertation asks is how did this organization stage such popular and well-attended protests during a period when leftist political activity seemed to have died out, and little mass protest was taking place. The thesis also explores why the Clamshell Alliance disintegrated at the same time as the anti-nuclear power movement's cause was gaining public acceptance in the wake of the Three Mile Island power-plant accident. The thesis finds that the principal resources the Clamshell drew upon to solve the problems of organizational formation were the activists, organizations, and ideology of the surviving New Left. The dissertation studies the struggles of the Clamshell Alliance as an example of the recurrent problems of leftist political activism in the U.S. It is concluded that only under special conditions can protest outside of regular political channels be both popular and effective. It is also proved that a larger organizational and ideological legacy of the sixties remains than is generally recongnized. Leftist beliefs continued to have adherents even after the protests stopped. Further, many individuals who came to political maturity after the sixties also were found to hold leftist beliefs. However, the political potential of this group can only be realized when an organization temporarily overcomes the barriers to mass leftist political action by developing an issue and a set of tactics that can appeal to leftists and nonleftists alike. Between such special acts of innovation the Left remains a political undercurrent outside of mainstream politics and without a means of effective influence because of its unwillingness to engage in conventional politics

    The hyperglycaemic clamp technique and the frequently sampled IVGTT are unsuitable techniques to assess beta cell function (BCF) in large cohorts. Therefore, the aim of this study was to evaluate the discriminatory ability of simple OGTT-based BCF indices for prediction of prediabetes (meaning impaired fasting glucose and/or impaired glucose tolerance) and type 2 diabetes. Glucose metabolism status was assessed by 2 h 75 g OGTT at baseline (n = 476, mean age 59.2 years, 38.7% women) and after 7 years of follow-up (n = 416) in the Cohort on Diabetes and Atherosclerosis Maastricht (CODAM) study (1999-2009). Baseline plasma glucose, insulin and C-peptide values during OGTTs were used to calculate 21 simple indices of BCF. Disposition indices (BCF index × Matsuda index), to compensate for the prevailing level of insulin resistance, were calculated for the BCF indices with the best discriminatory abilities. The discriminatory ability of the BCF indices was estimated by the area under the receiver operating characteristics curve (ROC AUC) with an outcome of incident prediabetes (n = 73) or type 2 diabetes (n = 60 and n = 18 cases, respectively, in individuals who were non-diabetic or had normal glucose metabolism at baseline). For incident prediabetes (n = 73), all ROC AUCs were less than 70%, whereas for incident type 2 diabetes, I 30 /I 0 , CP 30 /CP 0 , ΔI 30 /ΔG 30 , ΔCP 30 /ΔG 30 (where I, CP and G are the plasma concentrations of insulin, C-peptide and glucose, respectively, at the times indicated), and corrected insulin response at 30 min had ROC AUCs over 70%. In at-baseline non-diabetic individuals, disposition indices ΔI 30 /ΔG 30 , ΔCP 30 /ΔG 30 and corrected insulin response at 30 min had ROC AUCs of over 80% for incident type 2 diabetes. Moreover, these BCF disposition indices had significantly better discriminatory abilities for incident type 2 diabetes than the Matsuda index alone. BCF indices reflecting early

    1998-01-01

    Several IAEA publications consider the role of training and particularly the role of simulator training to enhance the safety of NPP operations. Initially, the focus was on full scope simulators for the training of main control room operators. Experience shows that other types of simulator are also effective tools that allow simulator training for a broader range of target groups and training objectives. This report provides guidance to training centers and suppliers on the proper selection, specification, design and use of various forms of simulators. In addition, it provides examples of their use in several Member States. This report is the result of a series of advisory and consultants meetings held in the framework of the International Working Group on Nuclear Power Plant Control and Instrumentation (IWG-NPPCI) in 1995-1996

  2. Management of ageing of I and C equipment in nuclear power plants. Report prepared within the framework of the International Working Group on Nuclear Power Plant Control and Instrumentation

    2000-06-01

    Experience has shown that ageing and obsolescence have the potential to cause the maintainability and operability of many instrumentation and control (I and C) systems to deteriorate well before the end of plant life. An I and C ageing management strategy is therefore required to control and minimize this threat. This report gives guidance on how to develop such a strategy and provides examples and supporting information on how established and recently developed maintenance, surveillance, and testing techniques may be employed to support the strategy. In some cases, equipment refurbishment may be necessary and guidance on this subject is given in a companion publication (IAEA-TECDOC-1016, Modernization of Instrumentation and Control in Nuclear Power Plants, IAEA, Vienna, 1998). The International Working Group on Nuclear Power Plant Control and Instrumentation (IWG-NPPCI) of the IAEA proposed in 1995 that a technical report be prepared to provide general guidelines on the management of ageing of important I and C equipment in nuclear power plants. The purpose of the report would be to guide the worldwide nuclear industry on potential effects of I and C ageing on plant safety and economy, and the means that are available to help minimize or eliminate any detrimental consequences of ageing. In response, a consultants meeting of five experts from Finland, France, Germany, the United Kingdom and the USA was held by the IAEA in Vienna in September 1997 to exchange national experience on the subject and to discuss the possible content of the report. The group of experts was tasked with bringing together all the information that is available on I and C ageing and ageing management methods. After a thorough discussion and analysis of the available information, an extended outline of the report on the subject was produced. The purpose of the extended outline was to identify a structure of the report, bring together information available at the moment and to provide guidance

  3. Information integration in control rooms and technical offices in nuclear power plants. Report prepared within the framework of the International Working Group on Nuclear Power Plant Control and Instrumentation

    2001-11-01

    The majority of the nuclear power plants in the world were designed 25 to 45 years ago. The information, instrumentation, safety, and control systems in these plant designs were based on analog, relay, and primitive digital technology. Computers that were available when most of the nuclear power plants were built were unsophisticated compared with those currently available. These less powerful machines with limited computational capabilities and memory were used to collect and store information. The main means for obtaining information from the plant were analog meters and strip chart recorders. In many cases these pieces of data had to be integrated and correlated with other data manually, in order to be usable. Procedures and plant information resided on paper only and were frequently hard to find and access in a timely manner. This report provides guidance to help with the integration of information in order to enhance the usability and usefulness of the information. It can also be used to help avoid the pitfalls that can occur when implementing new systems with respect to the information they need and produce. This reports philosophy is based on three important issues that allow the convenient structuring of the problem and to keep all of its important features. The first issue is the process of information systems integration and use. This is achieved by long term planning and the creation of the plant infrastructure plan. The second is to take care of the end users' needs in relation to their abilities. This is realized through analyses of user needs. Third is the design of the human-system interface (HSI), for example to distinguish between types of information for use in the plant control room and in technical offices. The development of this report was initiated by the IAEA International Working Group on Nuclear Power Plant Control and Instrumentation (IWG-NPPCI). It is a logical follow-up to IAEA-TECDOC-1016, Modernization of Instrumentation and Control

    The objective of the IAEA's International Working Group on Life Management of Nuclear Power Plants (IWG-LMNPP) is to provide the Member States with information and guidance on design aspects, material selection, testing, maintenance, monitoring and mitigation of degradation related to major components with the aim to assure high availability and safe operation of NPPs. Technical documents and reports on proceedings of specialists meetings on many of these topics have been produced or are in preparation. Coordination of research aimed at understanding the phenomena which occur and the consequent degradation mechanisms is an extensive field of the IWG-LMNPP activities. Radiation embrittlement of reactor pressure vessel steels has been a major subject of concern. Thermal degradation, corrosion and fatigue are also considered to be very significant.

    1999-01-01

    The need to develop good specifications of requirements for instrument and control (I and C) systems applies throughout the world and is becoming more and more important as more upgrades are planned. Better guidance on how to develop good requirements specifications would support safer, more effective and more economical refits and upgrades. The need for this was pointed out by the IAEA International Working Group on Nuclear Power Plant Control and Instrumentation (IWG-NPPCI). This report is the result of a series of advisory and consultants meetings held by the IAEA in 1997 and 1998 in Vienna. The scope of the activities described covers a methodology for the determination of requirements and the development of the necessary specifications and plans needed through the life-cycle of digital instrumentation and control systems. It is restricted to technical aspects and indicates subjects which should be included in specifications and plans at different phases

    1988-01-01

    The accident at the Chernobyl reactor in April 1986 had serious consequences, not just for Russia but for many countries in Europe. Following the accident, the National Society for Clean Air formed a Working Group to look at the Society's policy on civil nuclear power. Its finding and recommendations are presented in this first report. The subject was considered under several headings - radioactivity (public education in measurement and dose evaluation), emergency procedures in the event of incidents overseas, radiation monitoring, a national monitoring and information service, plant safety, nuclear materials handling and radioactive waste disposal, energy policy and conservation. Four main recommendations are made on public education, risk assessment and radiation monitoring, radioactive waste disposal and energy policy. (U.K.)

    There is an apparent paradox in Britain`s privatisation programme. It was carried out by an administration which proclaimed the virtues of market liberalisation, but its main feature was the ownership transfer, not liberalisation. The privatisation schemes, determined by the interplay between government and powerful pressure groups, are now leading to consequences in utility markets with some dangers of re-politicisation. [Italiano] Vi e` un evidente paradosso nella privatizzazione inglese: portata avanti da un`amministrazione che proclamava le virtu` del libero mercato, la sua principale caratteristica e` stata il cambiamento di proprieta`, non la liberalizzazione. Le modalita` della privatizzazione, determinate dall`interagire del governo con potenti gruppi di pressione, stanno ora ripercuotendosi sui mercati delle utility, con il pericolo di una loro ri-politicizzazione.

  10. Small power and heat generation systems on the basis of propulsion and innovative reactor technologies. Proceedings of an advisory group meeting

    International Nuclear Information System (INIS)

    2000-09-01

    In the future for developing regions and remote areas one or two power reactors in the 50 MWe to 100 MWe range could be appropriately applied for electricity and heat generation. Introducing and managing such a small program with conventional reactor systems would require a mature supporting technological infrastructure and many skilled highly-trained staff at the site, which might be a problem in some countries. An increased number of small conventional reactors would increase the burden and expenditure for assuring security and non-proliferation. To this end, the time has come to develop an innovative small reactor concept which meets the following requirements: reliable, safe operation with a minimum maintenance and supporting infrastructure, economic competitiveness with alternative energy sources available to the candidate sites, and significant improvements in proliferation resistance relative to existing reactor systems. Successful resolution of such a problem requires a comprehensive system approach that considers all aspects of manufacturing, transportation, operation and ultimate disposal. Some elements of this approach have been used previously in the development of propulsion nuclear power systems, with consideration given to many diverse requirements such as highly autonomous operation for a long period of time, no planned maintenance, no on-site refueling and ultimate disposition. It is with this focus that the IAEA convened the Advisory Group on Propulsion Reactor technologies for Civilian Applications

    Platinum group metal-free (PGM-free) catalyst with different loadings was investigated in air breathing electrodes microbial fuel cells (MFCs). Firstly, the electrocatalytic activity towards oxygen reduction reaction (ORR) of the catalyst was investigated by rotating ring disk electrode (RRDE) setup with different catalyst loadings. The results showed that higher loading led to an increased in the half wave potential and the limiting current and to a further decrease in the peroxide production. The electrons transferred also slightly increased with the catalyst loading up to the value of ≈3.75. This variation probably indicates that the catalyst investigated follow a 2x2e - transfer mechanism. The catalyst was integrated within activated carbon pellet-like air-breathing cathode in eight different loadings varying between 0.1 mgcm -2 and 10 mgcm -2 . Performance were enhanced gradually with the increase in catalyst content. Power densities varied between 90 ± 9 μWcm -2 and 262 ± 4 μWcm -2 with catalyst loading of 0.1 mgcm -2 and 10 mgcm -2 respectively. Cost assessments related to the catalyst performance are presented. An increase in catalyst utilization led to an increase in power generated with a substantial increase in the whole costs. Also a decrease in performance due to cathode/catalyst deterioration over time led to a further increase in the costs.

    An Fe group ternary nanoalloy (NA) catalyst enabled selective electrocatalysis towards CO2-free power generation from highly deliverable ethylene glycol (EG). A solid-solution-type FeCoNi NA catalyst supported on carbon was prepared by a two-step reduction method. High-resolution electron microscopy techniques identified atomic-level mixing of constituent elements in the nanoalloy. We examined the distribution of oxidised species, including CO2, produced on the FeCoNi nanoalloy catalyst in the EG electrooxidation under alkaline conditions. The FeCoNi nanoalloy catalyst exhibited the highest selectivities toward the formation of C2 products and to oxalic acid, i.e., 99 and 60%, respectively, at 0.4 V vs. the reversible hydrogen electrode (RHE), without CO2 generation. We successfully generated power by a direct EG alkaline fuel cell employing the FeCoNi nanoalloy catalyst and a solid-oxide electrolyte with oxygen reduction ability, i.e., a completely precious-metal-free system.

    The objective of this paper is to develop strategies useful for raising prices of rural power in India. Such power is currently subsidized and policymakers are eager to make the transition to more efficient prices. The traditionally used measure, willingness to pay (WTP), is shown to have no useful policy implications due to the rationing of power. Using survey data from rural Andhra Pradesh, we show that the utility's cost of power exceeds the income generated by the power. This suggests a political problem - the possibility that low power prices have led to large-scale farming of unproductive land - that will be hard to resolve. Our survey also shows that subsidies are regressive with income. We use measured WTP for higher income groups to propose a discriminatory pricing regime that will raise total revenue by 20%. When combined with removing the causes of motor burnout, such as voltage fluctuations, and eliminating rostering, subsidies can be reduced substantially but probably remain too high to be resolved without political action.

  17. Management of Operational Safety in Nuclear Power Plants. INSAG-13. A report by the International Nuclear Safety Advisory Group (Russian Edition)

    International Nuclear Information System (INIS)

    2015-01-01

    The International Atomic Energy Agency's activities relating to nuclear safety are based upon a number of premises. First and foremost, each Member State bears full responsibility for the safety of its nuclear facilities. States can be advised, but they cannot be relieved of this responsibility. Secondly, much can be gained by exchanging experience; lessons learned can prevent accidents. Finally, the image of nuclear safety is international; a serious accident anywhere affects the public's view of nuclear power everywhere. With the intention of strengthening its contribution to ensuring the safety of nuclear power plants, the IAEA established the International Nuclear Safety Advisory Group (INSAG), whose duties include serving as a forum for the exchange of information on nuclear safety issues of international significance and formulating, where possible, commonly shared safety principles. Engineering issues have received close attention from the nuclear community over many years. However, it is only in the last decade or so that organizational and cultural issues have been identified as vital to achieving safe operation. INSAG's publication No. 4 has been widely recognized as a milestone in advancing thinking about safety culture in the nuclear community and more widely. The present report deals with the framework for safety management that is necessary in organizations in order to promote safety culture. It deals with the general principles underlying the management of operational safety in a systematic way and provides guidance on good practices. It also draws on the results of audits and reviews to highlight how shortfalls in safety management have led to incidents at nuclear power plants. In addition, several specific issues are raised which are particularly topical in view of organizational changes that are taking place in the nuclear industry in various countries. Advice is given on how safety can be managed during organizational change, how

    International Nuclear Information System (INIS)

    2000-03-01

    This report reviews possible types of anomalies that are related to software in nuclear power plants, outlines techniques that can be used to identify anomalies throughout the entire software life-cycle, and discusses important issues that must be considered during anomaly investigation and resolution. Typically, anomalies are identified, investigated and resolved during the normal process of developing or maintaining plant software, where these activities are covered by procedures and tools that are part of this process. Nevertheless, to reduce the number and impact of anomalies under plant operating conditions, it is important to ensure that good plans, procedures and tools are in place throughout the software life-cycle. The need for this was pointed out by the IAEA International Working Group on Nuclear Power Plant Control and Instrumentation (IWG-NPPCI). The report is the result of a series of consultants meetings held by the IAEA in 1997 and 1998 in Vienna. It was prepared with the participation and contributions of experts from Austria, Canada, Germany, Hungary, the United Kingdom and the United States of America. The scope of activities described in this report covers a methodology for anomaly identification, anomaly investigation and anomaly resolution. The activities to be done within these steps strongly depend on the safety category of the software, the actual life-cycle phase of the software, the type of the software and the severity of the anomaly

    This meeting, organised by CRISM-PROMETEY in St Petersburg, Russia, is held to honour the memory of Academician Myrddin Davies, who passed away due to a tragic road accident on 11 March 2003 in Stretton, England. Academician Myrddin Davies started technical collaboration with the IAEA in the early 1980s, and in 1985 became chairman of the International Working Group on Reliability of Reactor Pressure Components (IWG-RRPC). Under his chairmanship this grew to become the Technical Working Group on Life Management of Nuclear Power Plants (TWG-LMNPP) covering broader issues and with world wide collaboration. An insight to the creation, working methods and achievements of the TWG-LMNPP is given in this paper. Acad. Myrddin Davies was a competent chairman at many specialist meetings, major conferences hosted by IAEA, other European organizations and Nuclear Engineering International activities. The direction given to the TWG-LMNPP by Acad. Myrddin Davies is shown to have made a significant contribution to the safe use of nuclear energy. Major contributions to nuclear technology of the TWG-LMNPP, during the Chairmanship of Myrddin Davies, are thus cited

    The obesity epidemic has major public health consequences. Expert dietetic and behavioural counselling with intensive follow-up is effective, but resource requirements severely restrict widespread implementation in primary care, where most patients are managed. We aimed to estimate the effectiveness and cost-effectiveness of an internet-based behavioural intervention (POWeR+) combined with brief practice nurse support in primary care. We did this pragmatic, parallel-group, randomised controlled trial at 56 primary care practices in central and south England. Eligible adults aged 18 years or older with a BMI of 30 kg/m(2) or more (or ≥28 kg/m(2) with hypertension, hypercholesterolaemia, or diabetes) registered online with POWeR+-a 24 session, web-based, weight management intervention lasting 6 months. After registration, the website automatically randomly assigned patients (1:1:1), via computer-generated random numbers, to receive evidence-based dietetic advice to swap foods for similar, but healthier, choices and increase fruit and vegetable intake, in addition to 6 monthly nurse follow-up (control group); web-based intervention and face-to-face nurse support (POWeR+Face-to-face [POWeR+F]; up to seven nurse contacts over 6 months); or web-based intervention and remote nurse support (POWeR+Remote [POWeR+R]; up to five emails or brief phone calls over 6 months). Participants and investigators were masked to group allocation at the point of randomisation; masking of participants was not possible after randomisation. The primary outcome was weight loss averaged over 12 months. We did a secondary analysis of weight to measure maintenance of 5% weight loss at months 6 and 12. We modelled the cost-effectiveness of each intervention. We did analysis by intention to treat, with multiple imputation for missing data. This trial is registered as an International Standard Randomised Controlled Trial, number ISRCTN21244703. Between Jan 30, 2013, and March 20, 2014, 818

    2002-12-01

    The introduction of software based instrumentation and control (I and C) systems for use in nuclear power plants, mainly due to I and C modernization activities, has raised many issues of safety and economics. Many of these issues have been raised in the IAEA Technical Working Group on Nuclear Power Plant Control and Instrumentation (TWG-NPPCI) meetings and by other organizations, such as the OECD and the European Commission. One increasingly important issue is the need for engineering solutions to justify them for the cost effective assessment and deployment of software based I and C systems. To address this important issue, the IAEA put together the Co-ordinated Research Project (CRP) on Solutions for Cost Effective Assessments of Software based I and C Systems. The overall objective of the project is to facilitate the cost effective assessment of software based I and C systems in nuclear power plants. This is necessary to address obsolescence issues, to introduce new beneficial functionality, and to improve overall performance. The engineering solutions developed in this CRP will contribute to this overall objective. The objective of the CRP was reached through co-ordinated research and collected experience in the areas of project management; requirements specifications; use of software explicitly designed for nuclear applications, use of commercial off the shelf (COTS) products, generic pre-qualification of systems and components; safety and reliability enhancements; verification and validation; and licensing impact. This TECDOC is the result of the research and collected experience put together under this CRP. The CRP participants gave presentations on their work performed as part of this CRP at the various meetings of the group. The first meeting of the CRP was held in Vienna on 8-12 November 1999 in which the participants developed the objectives, scope, and outline of this report. The second meeting was held in Halden, Norway on 4-8 December 2000 and the

    A three-group model (PLUTON) is described, which predicts the power density distribution, plutonium buildup, and burnup profiles across the fuel pellet radius as a function of in-pile time and parameters characterizing the type of reactor system with respect to fuel temperature and changes of density during the irradiation period. The PLUTON model is a part of two fuel performance codes (ASFAD and FEMAXI-V), which provide all necessary input for this model, mainly local temperatures and fuel matrix density across the radius. Comparisons between measurements and predictions of the PLUTON model are made on fuels with enrichments in the range 2.9 to 8.25% and with burnup between 21 000 and 64 000 MWd/t. It is shown that the PLUTON predictions are in good agreement with measurements as well as with predictions of the well-known TUBRNP model. The proposed model is flexibly applicable for all types of light water reactor (LWR) fuels, including mixed oxide, and for fuel tested in the Organization for Economic Corporation and Development's Halden heavy water reactor. The PLUTON three-group model is based on analytical (theoretical) consideration of neutron absorption in a resonant region of the fuel in its apparent form. It makes the model more flexible in comparison with the semi-empirical TUBRNP one-group model and allows the physically based model analysis of commercial LWR-type fuels at high burnup as well as analysis of experimental fuel rods tested in the Halden heavy water reactor, which is one of the main test reactors in the world. The differences in fuel behavior in the Halden reactor in terms of burnup distribution and plutonium buildup can be more clearly understood with the PLUTON model

    We isolated and characterized a peptide fragment corresponding to amino acid sequence 14-28 of human osteocalcin in urine from Paget's disease, and developed a polyclonal antibody reactive to this peptide in urine. We used this antibody to measure urinary fragments of osteocalcin and compared to efficacy of the urinary osteocalcin assay with a serum osteocalcin (sOC) assay (ELISA-Osteo, Cis-Bio International) to monitor the short-term changes in bone turnover in response to alendronate treatment. The synthetic peptide-based urinary osteocalcin (uOC) radioimmunoassay (RIA) showed an analytical sensitivity of 6.25 ng/mL, standard curve range of 3.12-400 ng/mL, and mean intra- (n = 20) and interassay (n = 30) coefficient of variation (CV) of sALP) (Alkphose-B, Metra Biosystems) in serum samples. The percent change data obtained between baseline and 30 days (n = 18) posttreatment suggested a rapid decline in uOC concentration (-27%, p sALP (-3.4%, p = 0.689), two specific markers of bone formation. As expected, due to the coupling of bone formation and bone resorption, the concentration of all markers showed a 30%-45% decline compared with baseline values after 90 days (n = 16) of treatment. Correlation of markers after a 30 day treatment with alendronate revealed a higher correlation (r = 0.61, p sALP (r = -0.14, p = 0.295) with uNTx. Similarly, correlation coefficients with r values between 0.48 and 0.55 (p < 0.05) were observed between uOC, sNTx, and sCTx, whereas no significant correlation was observed between sOC and sNTx or sCTx. These results provide indirect evidence that fragments measured by the urine assay probably originated from bone resorption, and suggest that the uOC assay could be used to assess short-term changes in bone metabolism with regard to osteocalcin.

    To assess the transcultural equivalency of the Spanish version of the Fibromyalgia Rapid Screening Tool (FiRST) and its discriminatory ability in different Latin American samples. Validation study. Departments of Rheumatology in general hospitals and private centers; fibromyalgia unit in a university hospital. 350 chronic pain patients from Spain, Argentina, Mexico, Peru, and Ecuador. The cultural relevance of the Spanish version of the FiRST was evaluated. The ability of the FiRST as a screening tool for fibromyalgia was assessed by logistic regression analysis. To determine the degree to which potential confounders, such as differences in demographics, pain, affective distress, catastrophizing, and disability, might affect the discriminatory ability, the tool was reassessed by hierarchical multivariate logistic regression. Slightly different versions of the FiRST were recommended for use in each Latin American subsample. The FiRST showed acceptable criterion validity and was able to discriminate between fibromyalgia and non-fibromyalgia patients even after controlling for the effect of potential confounders. However, low specificities were observed in samples from Spain and Mexico. The Spanish version of the FiRST may be used as a screening tool for fibromyalgia in several Latin American subsamples, even in those patients with high scores on potential confounders. In Spain and Mexico, the low specificity of the FiRST suggests, however, that it would be best used to support a suspected diagnosis of fibromyalgia, rather than to exclude the diagnosis. © 2015 American Academy of Pain Medicine.

    From the beginning of 2002, Troyes prefecture has initiated a reflection about the management of a nuclear crisis caused by an accident at the Nogent-sur-Seine nuclear power plant. Five workshops have been created, dealing with the following themes: 'Administrative and economic organization', 'Health risk assessment and the epidemiology', 'Monitoring of environment', 'Movement in the contaminated area' and 'Decontamination of soil and Food chain'. The first results of the 'Decontamination of soil and Food chain' working group, which involves the District Agricultural and Forestry Department, the Farmer's Association, the Institute for Radiological Protection and Nuclear Safety and the Veterinary Division are presented in the poster. The scenario that had been developed for the accident considers the release of 3 radionuclides ( 131 I, 134 Cs and 137 Cs) in the environment. The scale of the crisis didn't require the evacuation and the sheltering of the population during the emergency phase. The consequences on the local agricultural products (cereal, beetroot, vine, milk, cow meat...) have been assessed up to 50 km and different strategies of agricultural countermeasures have been studied regarding to the local constraints (soil types, surfaces and quantities concerned) and to the consequences of their implementation (waste types and quantities, costs). Then, decision-making diagrams summed up the technical results and allowed to deepen the global thought. (author)

  7. Validation and predictive power of radiation therapy oncology group (RTOG) recursive partitioning analysis classes for malignant glioma patients: a report using RTOG 90-06

    1996-01-01

    Background/Purpose: The recursive partitioning analysis (RPA) classes for malignant glioma patients were previously established by Curran et al. (JNCI 85:704-10, 1993) using data on over 1500 patients from the Radiation Therapy Oncology Group (RTOG). The current analysis was to validate the RPA classes on a new dataset (RTOG 90-06) and determine the predictive power of the RPA classes. Patients and Methods: There are six RPA classes for malignant glioma patients that comprise distinct groups of patients with significantly different survival outcome. RTOG 90-06 is a randomized phase III study of 712 patients accrued from 1990 to 1994. The minimum potential follow-up is 18 months. The treatment arms were combined for the purpose of this analysis. There were 84, 13, 105, 240, 150, and 23 patients in the six RPA classes from RTOG 90-06. Results: The median survival times (MST) and two-year survivals for the six RPA classes in RTOG 90-06 are compared to those published by Curran et al. (JNCI 1993). The RPA classes appear in descending order in the following table. The MST and 2-year survivals for the RTOG RPA classes were within 95% confidence intervals of the 90-06 estimates for classes I, III, IV, and V. The RPA classes explained 43% of the variation (squared error loss). By comparison, a model containing only histology explains only 13% of the variation. The RPA classes are statistically distinct with all comparisons exceeding 0.0001, except those involving class II. Conclusion: The validity of the model is verified by the reliability of the RPA classes to define distinct groups with respect to survival. Further evidence is given by prediction of MST and 2-year survival for all classes except class II. The RPA classes explained a good portion of the variation in the data. RPA class II did not perform well which may be an artifact of the small sample size or an indication that this class is not distinct. The validation of the RPA classes attests to their usefulness as

    Purpose: The recursive partitioning analysis (RPA) classes for malignant glioma patients were previously established using data on over 1500 patients entered on Radiation Therapy Oncology Group (RTOG) clinical trials. The purpose of the current analysis was to validate the RPA classes with a new dataset (RTOG 90-06), determine the predictive power of the RPA classes, and establish the usefulness of the database norms for the RPA classes. Patients and Methods: There are six RPA classes for malignant glioma patients that comprise distinct groups of patients with significantly different survival outcome. RTOG 90-06 is a randomized Phase III study of 712 patients accrued from 1990 to 1994. The minimum potential follow-up is 18 months. The treatment arms were combined for the purpose of this analysis. There were 84, 13, 105, 240, 150, and 23 patients in the RPA Classes I-VI from RTOG 90-06, respectively. Results: The median survival times (MST) and 2-year survival rates for the six RPA classes in RTOG 90-06 are compared to those previously published. The MST and 2-year survival rates for the RTOG RPA classes were within 95% confidence intervals of the 90-06 estimates for Classes I, III, IV, and V. The RPA classes explained 43% of the variation (squared error loss). By comparison, a Cox model explains 30% of the variation. The RPA classes within RTOG 90-06 are statistically distinct with all comparisons exceeding 0.0001, except those involving Class II. A survival analysis from a prior RTOG study indicated that 72.0 Gy had superior outcome to literature controls; analysis of this data by RPA classes indicates the survival results were not superior to the RTOG database norms. Conclusion: The validity of the model is verified by the reliability of the RPA classes to define distinct groups with respect to survival. Further evidence is given by prediction of MST and 2-year survival for all classes except Class II. The RPA classes explained a good portion of the variation in

    To examine the feasibility, safety, and secondary benefit potential of exoskeleton-assisted walking with one device for persons with multiple sclerosis (MS). Single-group longitudinal preliminary study with 8-week baseline, 8-week intervention, and 4-week follow-up. Outpatient MS clinic, tertiary care hospital. Participants (N=13; age range, 38-62y) were mostly women with Expanded Disability Status Scale scores ranging from 5.5 to 7.0. Exoskeleton-assisted walk training. Primary outcomes were accessibility (enrollment/screen pass), tolerability (completion/dropout), learnability (time to event for standing, walking, and sitting with little or no assistance), acceptability (satisfaction on the device subscale of the Quebec User Evaluation of Satisfaction with Assistive Technology version 2), and safety (event rates standardized to person-time exposure in the powered exoskeleton). Secondary outcomes were walking without the device (timed 25-foot walk test and 6-minute walk test distance), spasticity (Modified Ashworth Scale), and health-related quality of life (Patient-Reported Outcomes Measurement and Information System pain interference and Quality of Life in Neurological Conditions fatigue, sleep disturbance, depression, and positive affect and well-being). The device was accessible to 11 and tolerated by 5 participants. Learnability was moderate, with 5 to 15 sessions required to walk with minimal assistance. Safety was good; the highest adverse event rate was for skin issues at 151 per 1000 hours' exposure. Acceptability ranged from not very satisfied to very satisfied. Participants who walked routinely improved qualitatively on sitting, standing, or walking posture. Two participants improved and 2 worsened on ≥1 quality of life domain. The pattern of spasticity scores may indicate potential benefit. The device appeared feasible and safe for about a third of our sample, for whom routine exoskeleton-assisted walking may offer secondary benefits. Copyright

  12. State powers and responsibilities concerning the flow of waste

    International Nuclear Information System (INIS)

    Snyder, Patrick M.; Monaco, Cindy M.

    1992-01-01

    The primary source of federal jurisdiction over the transportation and management of waste is derived from the Commerce Clause of the U.S. Constitution. That authority is of two main types - active, which empowers federal supervision over matters affecting commerce, and passive, which restrains state activity regarding commerce-related issues. The passive, or dormant, powers prevent a state from undertaking economic protectionist actions, but they do not prevent legitimate regulation for public health and safety where there is not a less intrusive alternative. The Commerce Clause does not prohibit states from making market-based decisions as proprietors, and discriminatory activities may be undertaken in that capacity. A federally approved compact empowers states or groups of states to act in ways that would otherwise be precluded by the Commerce Clause. The public policy issues at work in the above situations are discussed. Several proposals to revise the Low-Level Radioactive Waste Policy Amendments Act to conform with these principles are described. (author)

The forages were sampled in Spring, Summer and Winter, with four replications per species per season. The n-alkanes C24 to C35, using C32 and C34 as internal markers, were considered in the analyses. Concentrations of n-alkanes in these species and their respective fractions (leaf blade, top and bottom portions of the stem and dead matter for grasses; leaves, top and bottom of stem and dead matter for legumes were evaluated by multivariate analysis. The discriminatory potential of n-alkanes was determined by the canonical variables analysis. The species and their respective fractions were divided into groups by cluster analysis. N-alkanes with the smallest potential discriminatory potential were: C26, C29, C25, C27 and C28 (spring, C26, C28, C27, C30 and C29 (summer and C28, C26, C25, C29 and C27 (winter. The n-alkanes in the spring and winter samples allowed discrimination of Coast-cross leaf blade from the top and bottom stems portions of this grass and between grass and legumes. It was possible to discriminate fractions of nutritional importance of Brachiaria brizantha, leaf blade and higher portion of stem in the summer. The multivariate analysis, the canonical variables and the cluster analysis are good procedures to be used in n-alkanes studies for herbivores diets discriminating.

  15. Harmonization of the licensing process for digital instrumentation and control systems in nuclear power plants. Report prepared within the framework of the Technical Working Group on Nuclear Power Plant Control and Instrumentation

    2002-12-01

    This report was prepared in response to the recommendation of the Technical Working Group on Nuclear Power Plant Control and Instrumentation (TWG-NPPCI). This recommendation was based on the recognition of the present diversity in national practices in licensing digital Instrumentation and control (I and C). The goal of this report is to promote harmonization of I and C licensing requirements in the Member States. It applies to I and C modernization, retrofits, upgrades, replacement, new installation, and other aspects of digital I and C in both existing and new nuclear power plants. It should be pointed out that a single publication, like this report, can only take the first step towards initiating a process leading to licensing requirements, which are more harmonized. It is therefore hoped that that this report will get a broad readership among those who can influence requirements that are set on digital I and C. This report provides general and high level recommendations to assist senior officials at utilities, vendor organizations, regulatory bodies, and their support organizations who are involved in the licensing of digital I and C. It is also intended to be read by persons participating in technical committees which are writing standards. The authors of this report believe that harmonization can be achieved through a consideration of the technical and scientific basis of high integrity digital I and C systems. It is also believed that many benefits can be reached in resolving various issues of a technical and engineering nature, which presently are creating controversies in the licensing of digital I and C in NPP safety applications. This publication is based on a consideration of the licensing process of I and C in a top down fashion to discuss generic principles to be applied when assessing digital I and C in NPP safety applications. This report gives an overview of the confidence building process in which evidence is created that digital I and C fulfils

    Minorities are in an inferior position in society and therefore vulnerable in many aspects. This study analyzes legislative vulnerability and aims to categorize as "weak" or "strong" the protection conferred by law to the following minorities: elderly, disabled, LGBT, Indians, women, children/ adolescents and black people. In order to do so, it was developed a documental research in 30 federal laws in which legal provisions were searched to protect minorities. Next, the articles were organized in the following categories: civil, criminal, administrative, labor and procedural, to be analyzed afterwards. Legal protection was considered "strong" when there were legal provisions that observed the five categories and "weak" when it did not meet this criterion. It was noted that six groups have "strong" legislative protection, which elides the assertion that minorities are outside the law. The exception is the LGBT group, whose legislative protection is weak. In addition, consecrating rights through laws strengthens the institutional channels for minorities to demand their rights. Finally, it was observed that the legislative protection granted tominorities is not homogeneous but rather discriminatory, and there is an interference by the majority group in the rights regulation of vulnerable groups.

  17. Opportunities for independent power in Ontario : perspective of TransCanada Power

    1998-01-01

    The recent white paper of the Government of Ontario and its implications for independent power producers (IPPs), vis-a-vis Ontario Hydro's market power and dominance, was discussed. The conclusion was that opportunities do exist to establish a competitive market for power which is open and transparent, has non-discriminatory transmission access, and in which price is a function of supply and demand. However, IPPs will need strong marketing skills to survive in the new marketplace. In addition to skills in power marketing, there will be strong demand for skills in gas marketing, operations, risk management, and financing. Prospects for interconnected markets and generators, and pipeline capacity considerations for Ontario were explored. The corporate profile of TransCanada Power (an affiliate of TransCanada Pipelines) was also reviewed. . 4 figs

  18. Management of life cycle and ageing at nuclear power plants: Improved I and C maintenance. Report prepared within the framework of the Technical Working Group on Nuclear Power Plant Control and Instrumentation

    International Nuclear Information System (INIS)

    2004-08-01

    The topic of this TECDOC was originally suggested in the May 2001 meeting of the IAEA Technical Working Group on Nuclear Power Plant Control and Instrumentation (TWG NPPCI). It was then approved by the IAEA for work to begin in 2002. It originated from the remarks of the TWG members that it is now time to address the instrumentation and control (I and C) ageing issues in terms of plant life management and licence renewal. Furthermore, the nuclear industry is believed to be able to survive only if plant economy is favourable in addition to plant safety. Therefore, in dealing with I and C ageing and obsolescence, one has to consider how to proceed in addressing this question, not only from a plant operational and safety standpoint, but also in the context of plant economy in terms of the cost of electricity production, and including initial and recurring capital costs. For this important reason, consideration of new technologies, such as on-line monitoring and in situ testing methods is recommended. These can be used not only to predict the consequences of ageing, and guard against it, but also to verify equipment performance throughout the lifetime of the plant, and help establish replacement schedules for I and C equipment, and predict residual life. The basic ageing and obsolescence management process involves: Understanding the ageing and obsolescence phenomena and identifying the (potential) effects on I and C; Addressing the specific impact of these effects on the plant taking into account operational profiles and analyzing the risks; Carrying out necessary mitigating actions to counteract the effects of ageing and obsolescence. Based on the above listed activities the ageing and obsolescence management programme needs to be an iterative process. The goal of this TECDOC is to provide the latest information on ageing, obsolescence, and performance monitoring of those I and C equipment that are classified as safety equipment and/or safety-related equipment, are

    Full Text Available Abstract Background Single nucleotide polymorphisms (SNPs and genes that exhibit presence/absence variation have provided informative marker sets for bacterial and viral genotyping. Identification of marker sets optimised for these purposes has been based on maximal generalized discriminatory power as measured by Simpson's Index of Diversity, or on the ability to identify specific variants. Here we describe the Not-N algorithm, which is designed to identify small sets of genetic markers diagnostic for user-specified subsets of known genetic variants. The algorithm does not treat the user-specified subset and the remaining genetic variants equally. Rather Not-N analysis is designed to underpin assays that provide 0% false negatives, which is very important for e.g. diagnostic procedures for clinically significant subgroups within microbial species. Results The Not-N algorithm has been incorporated into the "Minimum SNPs" computer program and used to derive genetic markers diagnostic for multilocus sequence typing-defined clonal complexes, hepatitis C virus (HCV subtypes, and phylogenetic clades defined by comparative genome hybridization (CGH data for Campylobacter jejuni, Yersinia enterocolitica and Clostridium difficile. Conclusion Not-N analysis is effective for identifying small sets of genetic markers diagnostic for microbial sub-groups. The best results to date have been obtained with CGH data from several bacterial species, and HCV sequence data.

    The Smart Grid Network was established in 2010 by the Danish climate and energy minister tasked with developing recommendations for future actions and initiatives that make it possible to handle up to 50% electricity from wind energy in the power system in 2020. The task of working group 1 of the Smart Grid Network is stated as: ''The group will, building on existing surveys and analyses of structures and constraints in the Danish electricity system 2020, define concrete ideas on the technical and system development needs for the electricity supply system when the goal of intelligent integration of 50 percent power generated by renewable energy must be met. The group should come up with concrete suggestions on how to make the power system future-oriented, such as new network and management architectures, more measuring equipment, optical sensors, and new computer and communications systems that can monitor, control and operate the power system with the aim that the new intelligence can contribute to a reliable and cost-effective power system that can handle the deployment of renewable energy''. The working group has focused on a general description of the whole overall system needs and more specifically on the power grid and its management and control. (LN)

    The description of the population of M. bovis strains circulating in France from 1978 to 2013 has highlighted the discriminating power of the MLVA among predominant spoligotype groups. In the present study we aimed to characterize clonal groups via MLVA and to better understand the strain's population structure. MLVA was performed with eight MIRU-VNTR loci, most of them defined by the Venomyc European consortium. The discriminatory index of each MLVA loci was calculated for SB0120, SB0134, SB0121 and the "F4-family", the main spoligotype groups in France. Differences in global DI per spoligotype, but also by locus within each spoligotype, were observed, which strongly suggest the clonal complex nature of these major groups. These MLVA results were compared to those of other European countries where strain collections had been characterized (Spain, Portugal, Italy, Northern Ireland and Belgium). Overall, QUB 3232 and ETR D are respectively the most and the least discriminative loci, regardless of the strains geographical origin. However, marked DI differences are observed in the rest of the MIRU-VNTR loci, again highlighting that strain genetic variability in a country depends on the dominant existing clonal complexes. A web application for M. bovis, including spoligotyping and MIRU-VNTR typing data, was developed to allow inter-laboratory comparison of field isolates. In conclusion, combination of typing methods is required for M. bovis optimum discrimination and differentiation of groups of strains. Thus, the loci employed for MLVA in a country should be those which are the most discriminative for the clonal complexes which characterize their M. bovis population. Copyright © 2016 Elsevier B.V.

  3. Group dynamics.

    Scandiffio, A L

    1990-12-01

    Group dynamics play a significant role within any organization, culture, or unit. The important thing to remember with any of these structures is that they are made up of people--people with different ideas, motivations, background, and sometimes different agendas. Most groups, formal or informal, look for a leader in an effort to maintain cohesiveness of the unit. At times, that cultural bond must be developed; once developed, it must be nurtured. There are also times that one of the group no longer finds the culture comfortable and begins to act out behaviorally. It is these times that become trying for the leader as she or he attempts to remain objective when that which was once in the building phase of group cohesiveness starts to fall apart. At all times, the manager must continue to view the employee creating the disturbance as an integral part of the group. It is at this time that it is beneficial to perceive the employee exhibiting problem behaviors as a special employee, as one who needs the benefit of your experience and skills, as one who is still part of the group. It is also during this time that the manager should focus upon her or his own views in the area of power, communication, and the corporate culture of the unit that one has established before attempting to understand another's point of view. Once we understand our own motivation and accept ourselves, it is then that we may move on to offer assistance to another. Once we understand our insecurities recognizing staff dysfunction as a symptom of system dysfunction will not be so threatening to the concept of the manager that we perceive ourselves to be. It takes a secure person to admit that she or he favors staff before deciding to do something to change things. The important thing to know is that it can be done. The favored staff can find a new way of relating to others, the special employee can find new modes of behavior (and even find self-esteem in the process), the group can find new ways

    2007-04-01

    Full Text Available Abstract Background MLVA (multiple-locus variable-number tandem repeat analysis is a reliable typing technique introduced recently to differentiate also isolates of Enterococcus faecium. We used the established VNTR (variable number of tandem repeats scheme to test its suitability to differentiate 58 E. faecium isolates representing mainly outbreaks and clusters of infections and colonizations among patients from 31 German hospitals. All isolates were vancomycin-resistant (vanA type. Typing results for MLVA are compared with results of macrorestriction analysis in PFGE (pulsed-field gel electrophoresis and MLST (multi-locus sequence typing. Results All 51 but one hospital isolates from 1996–2006 were assigned to the clonal complex (CC of epidemic-virulent, hospital-adapted lineages (MLST CC-17; MLVA CC-1 and differed from isolates of sporadic infections and colonizations (n = 7; 1991–1995 and other non-hospital origins (n = 27. Typing of all 58 hospital VRE revealed MLVA as the least discriminatory method (Simpson's diversity index 0.847 when compared to MLST (0.911 and PFGE (0.976. The two most common MLVA types MT-1 (n = 16 and MT-159 (n = 14 combined isolates of several MLST types including also major epidemic, hospital-adapted, clonal types (MT-1: ST-17, ST-18, ST-280, ST-282; MT-159: ST-78, ST-192, ST-203. These data clearly indicate that non-related E. faecium could possess an identical MLVA type being especially critical when MLVA is used to elucidate supposed outbreaks with E. faecium within a single or among different hospitals. Stability of a given MLVA profile MT-12 (ST-117 during an outbreak over a period of five years was also shown. Conclusion MLVA is a suitable method to assign isolates of E. faecium into distinct clonal complexes. To investigate outbreaks the current MLVA typing scheme for E. faecium does not discriminate enough and cannot be recommended as a standard superior to PFGE.

    Pulmonary hypertension (PH) patients have high mortality due to right ventricular failure. Predictors of poor prognostic outcome are increased right atrial volume (RAV) and elevated mean right atrial pressure (mRAP). Our aim was to determine whether RAV measured with 2D echocardiography (2DE) and 3D echocardiography (3DE) can detect elevated mRAP in patients evaluated for PH. Of 85 patients prospectively evaluated for PH, 44 patients (63 ± 15 years, 57% female) had 2DE, 3DE and right heart catheterization within 48 h and were in sinus rhythm. Maximum (RAV max ) and minimum (RAV min ) volumes were measured with 3DE. 2D maximum RAV and RA area, inferior vena cava diameter and collapsibility were measured. Invasive mRAP > 8 mmHg was predefined as elevated. RAV max and RAV min correlated with mRAP (r = 0·40 and r = 0·35, P8 mmHg. The optimal threshold was 57 ml m -2 for RAV max , 31 ml m -2 for RAV min and 36 ml m -2 for 2DE RAV. Enlarged RA measures with 2DE and 3DE have better discriminatory ability compared with IVC measures, to detect elevated mRAP in patients evaluated for PH. © 2016 The Authors.

  9. A standard description and costing methodology for the balance-of-plant items of a solar thermal electric power plant. Report of a multi-institutional working group

    Science.gov (United States)

    1983-01-01

    Standard descriptions for solar thermal power plants are established and uniform costing methodologies for nondevelopmental balance of plant (BOP) items are developed. The descriptions and methodologies developed are applicable to the major systems. These systems include the central receiver, parabolic dish, parabolic trough, hemispherical bowl, and solar pond. The standard plant is defined in terms of four categories comprising (1) solar energy collection, (2) power conversion, (3) energy storage, and (4) balance of plant. Each of these categories is described in terms of the type and function of components and/or subsystems within the category. A detailed description is given for the BOP category. BOP contains a number of nondevelopmental items that are common to all solar thermal systems. A standard methodology for determining the costs of these nondevelopmental BOP items is given. The methodology is presented in the form of cost equations involving cost factors such as unit costs. A set of baseline values for the normalized cost factors is also given.

    Aim: To evaluate the prevalence of coronary artery disease (CAD) in relation to risk of coronary heart disease (CHD) and assess plaque characteristics from coronary computed tomography (CT) angiography in asymptomatic and symptomatic patients. Materials and methods: Three hundred and ninety consecutive patients [asymptomatic group, n = 138; symptomatic group (atypical or non-anginal chest pain), n = 252] were retrospectively enrolled. They were subsequently classified into three CHD risk categories, based on the National Cholesterol Education Program guidelines, and 10 year risks of coronary events were calculated using Framingham risk score. CT was evaluated for stenosis, plaque composition, and coronary calcium scores. Results: CAD was observed in 42% of the asymptomatic group and 62% of the symptomatic group. In the former, the prevalence of CAD in low-, moderate- and high-risk subgroups was 21.4, 47.4 and 65%, respectively, and was 33.3, 74.4, and 72.4% in the symptomatic group. Framingham 10-year risks of coronary events were significantly higher in patients with CAD than in normal participants, and receiver operating characteristics curves showed that discriminatory power was poor in the asymptomatic group and symptomatic men, and good in symptomatic women. Of the participants in the asymptomatic group, 12% exhibited only non-calcified plaques and of the symptomatic group, 7% exhibited only non-calcified plaques. The coronary calcium score was significantly higher for significant stenosis than for non-significant stenosis in both groups. Conclusions: The prevalence of CAD was not negligible even in subgroups with low-to-moderate CHD risk. Additionally, the Framingham risk score was effective for predicting CAD only in symptomatic women. Coronary calcium scores correlated with significant stenosis; however, a sizeable percentage of both groups had only non-calcified plaques.

    Resolution of USI A-46 was accomplished May, 1992 with the issuance of the SER for the GIP, Revision 2. The implementation of the resolution for the SQUG plants will be completed by 1996. Both the USNRC and the SQUG utilities have expended considerable resources to effect a common understanding that the effort has been worth the price. The Training Program developed to ensure that the efforts expended by the SQUG was indeed worth the price will be a major contributor in the success of the implementation. All of the older nuclear power plants in the United States now have an alternative standard to determine seismic resistance using experience data- a standard against which they can be evaluated and found seismically adequate to achieve and maintain a safe and reliable shutdown when subjected to strong motion earthquakes

    The Past Global Changes (PAGES) project of IGBP and Future Earth supports research to understand the Earth's past environment to improve future climate predictions and inform strategies for sustainability. Within this framework, the PAGES 2k Network was established to provide a focus on the past 2000 years, a period that encompasses Medieval Climate Anomaly warming, Little Ice Age cooling, and recent anthropogenically-forced climate change. The results of these studies are used for testing earth system models, and for understanding decadal- to centennial-scale variability, which is needed for long-term planning. International coordination and cooperation among the nine regional Working Groups that make up the 2k Network has been critical to the success of PAGES 2k. The collaborative approach is moving toward scientific achievements across the regional groups, including: (i) the development of a community-driven open-access proxy climate database; (ii) integration of multi-resolution proxy records; (iii) development of multivariate climate reconstructions; and (iv) a leap forward in the spatial resolution of paleoclimate reconstructions. The last addition to the 2k Network, the Ocean2k Working Group has further innovated the collaborative approach by: (1) creating an open, receptive environment to discuss ideas exclusively in the virtual space; (2) employing an array of real-time collaborative software tools to enable communication, group document writing, and data analysis; (3) consolidating executive leadership teams to oversee project development and manage grassroots-style volunteer pools; and (4) embracing the value-added role that international and interdisciplinary science can play in advancing paleoclimate hypotheses critical to understanding future change. Ongoing efforts for the PAGES 2k Network are focused on developing new standards for data quality control and archiving. These tasks will provide the foundation for new and continuing "trans-regional" 2k

    Full Text Available In this article the features of social-relationship systems are analyzed based on the data from a sociopsychological empirical study conducted in two stages (2002 and 2014 on a large sample with the help of g. Kelly’s Repertory grid Technique. A. V. Petrovsky’s three-factor interpersonal-relationships model as interpreted for closed groups by M. Yu. Kondratev and the concept of the closed society as described by Karl Popper provide the foundation for the theoretical hypothesis we tested. The empirical data obtained in 2002 came from 391 participants of different ages who were living in provincial towns in the Nizhny Novgorod region. The elderly respondents (232 people had lived almost all their lives under the Soviet regime; the middle-aged respondents (159 people got their education and started their careers in the USSR. Soviet society is considered to be closed because of its authoritarian and collectivist nature, static social structure, and dogmatic ideology. It is argued that both closed societies and closed groups are characterized by a rigid hierarchical social structure, isolation from other systems, and depersonalization of social relations. We have proved that members of a closed group and citizens of a closed society have similar social-relationship matrices.

    To study the subjective differences in direct lip support assessments and to determine if dentists and laypeople are able to discern and correctly identify direct changes in lip support between flange and flangeless dentures. A random sample of 20 maxillary edentulous patients described in part 2 of the study was used for analysis. A total of 60 judges comprising 15 general dentists, 15 prosthodontists, and 30 laypeople, the majority of who were distinct from part 2 of the study, were recruited. All images used in this study were cropped at the infraorbital level and converted to black and white tone, to encourage the judges to focus on lip support. The judges were un-blinded to the study objectives and told what to look for, and were asked to rate the lip support of each of the 80 images on a 100 mm visual analog scale (VAS). The judges then took a discriminatory sensory analysis test (triangle test) where they were required to correctly identify the image with a flangeless denture out of a set of 3 images. Both the VAS and triangle test ratings were conducted twice in a random order, and mean ratings were used for all analyses. The overall VAS ratings of lip support for images with flangeless dentures were slightly lower compared to images with labial flanges, and this difference was statistically significant (p differences was too small (no greater than 5 mm on a 100-mm scale) to be clinically significant or meaningful. The differences in VAS ratings were not significant between the judges. For the triangle test, judges overall correctly identified the flangeless denture image in 55% of frontal image sets and 60% of profile image sets. The difference in correct identification rate between frontal and profile images was statistically significant (p difference in correct identification rate was statistically significant between various judges (p = 0.012). For all judges, the likelihood of correctly identifying images with flangeless dentures was significantly

    The increasing demand in the complexity, efficiency and reliability in modern industrial systems stimulated studies on control theory applied to the development of Monitoring and Fault Detection system. In this work a new Monitoring and Fault Detection methodology was developed using GMDH (Group Method of Data Handling) algorithm and Artificial Neural Networks (ANNs) which was applied to the IEA-R1 research reactor at IPEN. The Monitoring and Fault Detection system was developed in two parts: the first was dedicated to preprocess information, using GMDH algorithm; and the second part to the process information using ANNs. The GMDH algorithm was used in two different ways: firstly, the GMDH algorithm was used to generate a better database estimated, called matrix{sub z}, which was used to train the ANNs. After that, the GMDH was used to study the best set of variables to be used to train the ANNs, resulting in a best monitoring variable estimative. The methodology was developed and tested using five different models: one Theoretical Model and four Models using different sets of reactor variables. After an exhausting study dedicated to the sensors Monitoring, the Fault Detection in sensors was developed by simulating faults in the sensors database using values of 5%, 10%, 15% and 20% in these sensors database. The results obtained using GMDH algorithm in the choice of the best input variables to the ANNs were better than that using only ANNs, thus making possible the use of these methods in the implementation of a new Monitoring and Fault Detection methodology applied in sensors.

    2006-06-01

    The time is right to address nuclear power plant life management and ageing management issues in terms of processes and refurbishments for long term operation and license renewal aspects of heavy water reactors (HWRs) because some HWRs are close to the design life. In general, HWR nuclear power plant (NPP) owners would like to keep their NPPs in service as long as they can be operated safely and economically. This involves the consideration of a number of factors, such as the material condition of the plant, comparison with current safety standards, the socio-political climate and asset management/ business planning considerations. This TECDOC deals with organizational and managerial means to implement effective plan life management (PLiM) into existing plant in operating HWR NPPs. This TECDOC discusses the current trend of PLiM observed in NPPs to date and an overview of PLiM programmes and considerations. This includes key objectives of such programs, regulatory considerations, an overall integrated approach, organizational and technology infrastructure considerations, importance of effective plant data management and finally, human issues related to ageing and finally integration of PLiM with economic planning. Also general approach to HWR PLiM, including the key PLiM processes, life assessment for critical structures and components, conditions assessment of structures and components and obsolescence is mentioned. Technical aspects are described on component specific technology considerations for condition assessment, example of a proactive ageing management programme, and Ontario power generation experiences in appendices. Also country reports from Argentina, Canada, India, the Republic of Korea and Romania are attached in the annex to share practices and experiences to PLiM programme. This TECDOC is primarily addressed to both the management (decision makers) and technical staff (engineers and scientists) of NPP owners/operators and technical support

    Full Text Available Abstract Background Patients-Reported Outcomes (PRO are increasingly used in clinical and epidemiological research. Two main types of analytical strategies can be found for these data: classical test theory (CTT based on the observed scores and models coming from Item Response Theory (IRT. However, whether IRT or CTT would be the most appropriate method to analyse PRO data remains unknown. The statistical properties of CTT and IRT, regarding power and corresponding effect sizes, were compared. Methods Two-group cross-sectional studies were simulated for the comparison of PRO data using IRT or CTT-based analysis. For IRT, different scenarios were investigated according to whether items or person parameters were assumed to be known, to a certain extent for item parameters, from good to poor precision, or unknown and therefore had to be estimated. The powers obtained with IRT or CTT were compared and parameters having the strongest impact on them were identified. Results When person parameters were assumed to be unknown and items parameters to be either known or not, the power achieved using IRT or CTT were similar and always lower than the expected power using the well-known sample size formula for normally distributed endpoints. The number of items had a substantial impact on power for both methods. Conclusion Without any missing data, IRT and CTT seem to provide comparable power. The classical sample size formula for CTT seems to be adequate under some conditions but is not appropriate for IRT. In IRT, it seems important to take account of the number of items to obtain an accurate formula.

    We present a seismogenic source model for site-specific probabilistic seismic hazard assessment at the sites of Swiss nuclear power plants. Our model is one of four developed in the framework of the PEGASOS project; it contains a logic tree with nine levels of decision-making. The two primary sources of input used in the areal zonation developed by us are the historical and instrumental seismicity record and large-scale geological/rheological units. From this, we develop a zonation of six macro zones, refined in a series of seven decision steps up to a maximum of 13 zones. Within zones, activity rates are either assumed homogeneous or smoothed using a Gaussian kernel with width of 5 or 15 km. To estimate recurrence rate, we assume a double truncated Gutenberg-Richter law, and consider five models of recurrence parameters with different degrees of freedom. Models are weighted in the logic tree using a weighted Akaike score. The maximum magnitude is estimated following the EPRI approach. We perform extensive sensitivity analyses in rate and hazard space in order to assess the role of de-clustering, the completeness model, quarry contamination, border properties, stationarity, regional b-value and magnitude-dependent hypocentral depth.

    Quantitative PCR (qPCR) and community fingerprinting methods, such as the Terminal Restriction Fragment Length Polymorphism (T-RFLP) analysis,are well-suited techniques for the examination of microbial community structures. The use of phylum and class-specific primers can provide enhanced sensitivity and phylogenetic resolution as compared with domain-specific primers. To date, several phylum- and class-specific primers targeting the 16S ribosomal RNA gene have been published. However, many of these primers exhibit low discriminatory power against non-target bacteria in PCR. In this study, we evaluated the precision of certain published primers in silico and via specific PCR. We designed new qPCR and T-RFLP primer pairs (for the classes Alphaproteobacteria and Betaproteobacteria, and the phyla Bacteroidetes, Firmicutes and Actinobacteria) by combining the sequence information from a public dataset (SILVA SSU Ref 102 NR) with manual primer design. We evaluated the primer pairs via PCR using isolates of the above-mentioned groups and via screening of clone libraries from environmental soil samples and human faecal samples. As observed through theoretical and practical evaluation, the primers developed in this study showed a higher level of precision than previously published primers, thus allowing a deeper insight into microbial community dynamics.

    Posterior fossa ependymomas (EPN_PF) in children comprise two morphologically identical, but biologically distinct tumor entities. Group-A (EPN_PFA) tumors have a poor prognosis and require intensive therapy. In contrast, group-B tumors (EPN_PFB) exhibit excellent prognosis and the current consensus opinion recommends future clinical trials to test the possibility of treatment de-escalation in these patients. Therefore, distinguishing these two tumor subtypes is critical. EPN_PFA and EPN_PFB can be distinguished based on DNA methylation signatures, but these assays are not routinely available. We have previously shown that a subset of poorly prognostic childhood EPN_PF exhibits global reduction in H3K27me3. Therefore, we set out to determine whether a simple immunohistochemical assay for H3K27me3 could be used to segregate EPN_PFA from EPN_PFB tumors. We assembled a cohort of 230 childhood ependymomas and H3K27me3 immunohistochemistry was assessed as positive or negative in a blinded manner. H3K27me3 staining results were compared with DNA methylation-based subgroup information available in 112 samples [EPN_PFA (n = 72) and EPN_PFB tumors (n = 40)]. H3K27me3 staining was globally reduced in EPN_PFA tumors and immunohistochemistry showed 99% sensitivity and 100% specificity in segregating EPN_PFA from EPN_PFB tumors. Moreover, H3K27me3 immunostaining was sufficient to delineate patients with worse prognosis in two independent, non-overlapping cohorts (n = 133 and n = 97). In conclusion, immunohistochemical evaluation of H3K27me3 global reduction is an economic, easily available and readily adaptable method for defining high-risk EPN_PFA from low-risk posterior fossa EPN_PFB tumors to inform prognosis and to enable the design of future clinical trials.

    In 1974 the IAEA established a Nuclear Safety Standards (NUSS) programme within which 5 Codes and 55 Safety Guides have been produced in the areas of Governmental Organization, Siting, Design, Operation and Quality Assurance. The NUSS Codes and Guides are a collection of basic and derived requirements for the safety of nuclear power plants with thermal neutron reactors. They have been developed in such a manner as to ensure the broadest international consensus. This broad consensus is one of the reasons for the relatively general wording of the main principles and sometimes causes problems when these principles are applied in the design of nuclear power plants. The requirements, particularly those of the Codes, often need interpretation in specific cases. In many areas national regulations and technical standards are available, but often these leave some questions unanswered and their practical application on a case-by-case basis is necessary. To assist in the application and interpretation of the NUSS Safety Standards and Safety Guides, the preparation of a number of Safety Practices publications has been commenced. Ibis publication is intended to assist regulators and also operating organizations.

    The Smart Grid Network was established in 2010 by the Danish climate and energy minister tasked with developing recommendations for future actions and initiatives that make it possible to handle up to 50% electricity from wind energy in the power system in 2020. The task of working group 4 was to investigate what it takes to involve consumers in smart grid and how to create good conditions for new services related to smart grid. Against this background, the working group agreed the following recommendations: 1) Enhance consumer engagement. A prerequisite for electricity customers becoming involved in smart grid is that they have awareness and knowledge about the smart grid and their own possibilities for action in relation thereto. Therefore it is important that concepts such as smart grid and flexible electricity consumption gradually become popular among electric customers; 2) Minimize the risk. In order to promote electric customers' and other stakeholders' participation in the smart grid, the risk of this participation must be minimized. It is therefore recommended to enhance the skills of the professionals and to establish a common framework for security; 3) Make it easier to create new services. Part of the potential of smart grid can be realized through new services such as delivery of flexible electricity consumption for electric cars and heat pumps and the resale of local power generation at the customer. To facilitate the conditions for these services, the working group recommends that better access to relevant data is created, that the interoperability of smart grid solutions is strengthened, that requirements for buildings are made, that it is made easier to be an aggregator, and that test and inspiration laboratories for small and medium enterprises in the smart grid area are established.

  9. Operating and maintenance experience with computer-based systems in nuclear power plants - A report by the PWG-1 Task Group on Computer-based Systems Important to Safety

    1998-01-01

    This report was prepared by the Task Group on Computer-based Systems Important to Safety of the Principal Working Group No. 1. Canada had a leading role in this study. Operating and Maintenance Experience with Computer-based Systems in nuclear power plants is essential for improving and upgrading against potential failures. The present report summarises the observations and findings related to the use of digital technology in nuclear power plants. It also makes recommendations for future activities in Member Countries. Continued expansion of digital technology in nuclear power reactor has resulted in new safety and licensing issues, since the existing licensing review criteria were mainly based on the analogue devices used when the plants were designed. On the industry side, a consensus approach is needed to help stabilise and standardise the treatment of digital installations and upgrades while ensuring safety and reliability. On the regulatory side, new guidelines and regulatory requirements are needed to assess digital upgrades. Upgrades or new installation issues always involve potential for system failures. They are addressed specifically in the 'hazard' or 'failure' analysis, and it is in this context that they ultimately are resolved in the design and addressed in licensing. Failure Analysis is normally performed in parallel with the design, verification and validation (V and V), and implementation activities of the upgrades. Current standards and guidelines in France, U.S. and Canada recognise the importance of failure analysis in computer-based system design. Thus failure analysis is an integral part of the design and implementation process and is aimed at evaluating potential failure modes and cause of system failures. In this context, it is essential to define 'System' as the plant system affected by the upgrade, not the 'Computer' system. The identified failures would provide input to the design process in the form of design requirements or design

This work included visiting many Group X websites to find information on splinter group leaders and finding their statements to new and old members. This proved difficult because the splinter groups of Group X are united in beliefs, but differ in public opinion. They are eager to tear each other down, prove their superiority, and yet remain anonymous. After a few weeks of intense searching, a list of eight recruiting texts and eight radicalizing texts from a variety of Group X leaders were compiled.

  15. Technology working group

    Tsujikura, Y.

    2000-01-01

    The workshop of 26-27 june 2000, on nuclear power Plant LIfe Management (PLIM), also included working groups in which major issues facing PLIM activities for nuclear power plants were identified and discussed. The first group was on Technology. Utilities should consider required provisions capacity by properly maintaining and preserving the existing power plants to the extent practicable and taking into account growing demand, limits of energy conservation, and difficulties in finding new power plant sites. Generally, the extension of the life of nuclear power plant (e.g. from 40 years to 60 years) is an attractive option for utilities, as the marginal cost of most existing nuclear power plants is lower than that of almost all other power sources. It is also an attractive option for environmental protection. Consequently, PLIM has become an important issue in the context of the regulatory reform of the electricity markets. Therefore, the three main objectives of the Technology working group are: 1) Documenting how the safety of nuclear power plants being operated for the long-term has been confirmed, and suggesting ways of sharing this information. 2) Addressing development of advanced maintenance technologies necessary over the plant lifetime, and clarifying their technical challenges. 3) Suggesting potential areas of research and development that might, be necessary. Some potential examples of such research include: - improving the effectiveness of maintenance methods to assure detection of incipient faults; - providing cost effective preventive maintenance programmes; - furnishing systematic, cost-effective refurbishment programmes framed to be consistent with efforts to extend the time between re-fuelling; - developing a methodology that moves routine maintenance on-line without compromising safety.

    Small-scale production and distribution of power, heat and cooling (CHCP) for a group of buildings is described in this report on a general level. Possible system solutions are identified and a summary of the state-of-the-art is provided. Costs have been compared for different system solutions using a fictitious group of buildings in a case study. CHCP (Combined Heat, Cooling and Power) is an acronym used for a compact cogeneration unit (CHP) that also provides cooling, where cooling may be produced using an absorption cooling machine. The advantage of heat-driven cooling process combined with a cogeneration unit offers is an increase of the annual number of hours during which the cogeneration is operated. This should lead to an increased competitiveness for small-scale cogeneration also in Sweden, which should become even better if the price for electricity continues to increase. Systems with cogeneration and cooling are often associated with the concept of 'distributed generation' of electricity and with units in single buildings such as hotels, hospitals, offices, shopping centers etc. They could also be considered for groups of buildings connected to a small distribution network for district heating, and district cooling. Both steam and hot water are possible energy carriers. The focus of the study was small-scale cogeneration units in the range 0,1 to 2 MW{sub e} with natural gas as fuel. For the sake of the analysis of profitability and of investment, a fictitious area has been defined with four buildings: two hotels, an office and a shopping centre. The maximum total heat and cooling loads of this area are 8 MW heat and 3.5 MW cooling. The alternatives to heat-only boilers and electric chillers in each building studied were based on piping networks. The results from the calculations show that local production of electric power, heat and cooling is possible in buildings and areas with large energy consumption. With prices and assumptions as in the

    The article presents a study that aims at the apprehension of the group learning in a top management team composed by teachers in a Brazilian Waldorf school whose management is collective. After deciding to extend the school, they had problems recruiting teachers who were already trained based...... on the Steiner´s ideas, which created practical problems for conducting management activities. The research seeks to understand how that group of teachers collectively manage the school, facing the lack of resources, a significant heterogeneity in the relationships, and the conflicts and contradictions......, and they are interrelated to the group learning as the construction, maintenance and reconstruction of the intelligibility of practices. From this perspective, it can be said that learning is a practice and not an exceptional phenomenon. Building, maintaining and rebuilding the intelligibility is the group learning...

    Written by one of the subject’s foremost experts, this book focuses on the central developments and modern methods of the advanced theory of abelian groups, while remaining accessible, as an introduction and reference, to the non-specialist. It provides a coherent source for results scattered throughout the research literature with lots of new proofs. The presentation highlights major trends that have radically changed the modern character of the subject, in particular, the use of homological methods in the structure theory of various classes of abelian groups, and the use of advanced set-theoretical methods in the study of undecidability problems. The treatment of the latter trend includes Shelah’s seminal work on the undecidability in ZFC of Whitehead’s Problem; while the treatment of the former trend includes an extensive (but non-exhaustive) study of p-groups, torsion-free groups, mixed groups, and important classes of groups arising from ring theory. To prepare the reader to tackle these topics, th...

  17. Statistical power in parallel group point exposure studies with time-to-event outcomes: an empirical comparison of the performance of randomized controlled trials and the inverse probability of treatment weighting (IPTW) approach.

    Austin, Peter C; Schuster, Tibor; Platt, Robert W

    2015-10-15

    Estimating statistical power is an important component of the design of both randomized controlled trials (RCTs) and observational studies. Methods for estimating statistical power in RCTs have been well described and can be implemented simply. In observational studies, statistical methods must be used to remove the effects of confounding that can occur due to non-random treatment assignment. Inverse probability of treatment weighting (IPTW) using the propensity score is an attractive method for estimating the effects of treatment using observational data. However, sample size and power calculations have not been adequately described for these methods. We used an extensive series of Monte Carlo simulations to compare the statistical power of an IPTW analysis of an observational study with time-to-event outcomes with that of an analysis of a similarly-structured RCT. We examined the impact of four factors on the statistical power function: number of observed events, prevalence of treatment, the marginal hazard ratio, and the strength of the treatment-selection process. We found that, on average, an IPTW analysis had lower statistical power compared to an analysis of a similarly-structured RCT. The difference in statistical power increased as the magnitude of the treatment-selection model increased. The statistical power of an IPTW analysis tended to be lower than the statistical power of a similarly-structured RCT.

    Full text: In his review 'Genesis of Unified Gauge Theories' at the symposium in Honour of Abdus Salam (June, page 23), Tom Kibble of Imperial College, London, looked back to the physics events around Salam from 1959-67. He described how, in the early 1960s, people were pushing to enlarge the symmetry of strong interactions beyond the SU(2) of isospin and incorporate the additional strangeness quantum number. Kibble wrote - 'Salam had students working on every conceivable symmetry group. One of these was Yuval Ne'eman, who had the good fortune and/or prescience to work on SU(3). From that work, and of course from the independent work of Murray Gell- Mann, stemmed the Eightfold Way, with its triumphant vindication in the discovery of the omega-minus in 1964.' Yuval Ne'eman writes - 'I was the Defence Attaché at the Israeli Embassy in London and was admitted by Salam as a part-time graduate student when I arrived in 1958. I started research after resigning from the Embassy in May 1960. Salam suggested a problem: provide vector mesons with mass - the problem which was eventually solved by Higgs, Guralnik, Kibble,.... (as described by Kibble in his article). I explained to Salam that I had become interested in symmetry. Nobody at Imperial College at the time, other than Salam himself, was doing anything in groups, and attention further afield was focused on the rotation - SO(N) - groups. Reacting to my own half-baked schemes, Salam told me to forget about the rotation groups he taught us, and study group theory in depth, directing me to Eugene Dynkin's classification of Lie subalgebras, about which he had heard from Morton Hamermesh. I found Dynkin incomprehensible without first learning about Lie algebras from Henri Cartan's thesis, which luckily had been reproduced by Dynkin in his 1946 thesis, using his diagram method. From a copy of a translation of Dynkin's thesis which I found in the British Museum Library, I

    The workshop of 26-27 june 2000, on nuclear power Plant LIfe Management (PLIM), also included working groups in which major issues facing PLIM activities for nuclear power plants were identified and discussed. The third group was on Business. The discussion concerned the following points: There are concerns about retaining experienced/trained personnel, and maintaining a good working relationship among them, as well as about the closure of research facilities, the reduction in staff numbers under increasing economic pressure and the lack of new nuclear power plant constructions. The marginal cost of producing electricity is lower for most existing nuclear power plants than for almost all other energy sources. Refurbishment costs are usually relatively small compared with new investments. The ongoing regulatory reform of the electricity market will bring increasing competition. Although PLIM has been carried out in many countries with favourable results, there are still uncertainties which affect business decisions regarding financial and market risks in PLIM activities. Recommendations were made. (author)

  4. From the Dog Whistle to the Dog Scream: The Republican Party's (AbUse of Discriminatory speech in Electoral Campaigns and Party Politics

    Directory of Open Access Journals (Sweden)

    Luiza-Maria Filimon

    2016-12-01

    Full Text Available The 2016 U.S. presidential election can be described as nostalgic. On one hand, there was the fond remembrance of the Clinton administration characterized by a period of economic prosperity which overshadowed the more disastrous aftermath of various policies (the crime bill, the welfare reform, the Defense of Marriage Act, the repeal of the 1933 Glass-Steagall Act, etc.. On the other, the 2016 election brought to the surface a dormant longing for a privileged past rooted in open discrimination, inequality, segregation, and white supremacy, echoed by Donald Trump’s campaign. The Republican candidate had won the party’s nomination by openly and devoutly proselytizing against minority groups that allegedly threaten the fabric, integrity, and security of the United States. The more ethnic stereotypical caricatures and outright lies he employed in his speeches, the more successful his primary campaign was and the more he unnerved the Republican establishment, the general electorate, and the media. Yet Donald Trump’s campaign was not innovative by any means. Instead, as this study will argue, Trump’s electoral success during the primary elections can be in part attributed to the Republican Party’s decades-long history of strategic racism that has been instrumental in grooming the party’s base into Donald Trump’s supporters. In order to showcase that Trump’s ascendancy to the top of the Republican primary election was not a political accident, but a natural progression of decades-old officially sanctioned electoral policies, the study analyzes the origins behind the “dog whistle” practice, based on the model of strategic racism advanced by Ian Haney López. In conducting this research, I provide examples from U.S. public officials – past and present – and also highlight the role of the media in the propagation and cultivation of dog whistle politics.

    Proper management of dynamic systems (e.g. cooling systems of nuclear power plants or production and warehousing) is important to ensure public safety and economic success. So far, research has provided broad evidence for systematic shortcomings in individuals' control performance of dynamic systems. This research aims to investigate whether groups manifest synergy (Larson, 2010) and outperform individuals and if so, what processes lead to these performance advantages. In three experiments - including simulations of a nuclear power plant and a business setting - I compare the control performance of three-person-groups to the average individual performance and to nominal groups (N = 105 groups per experiment). The nominal group condition captures the statistical advantage of aggregated group judgements not due to social interaction. First, results show a superior performance of groups compared to individuals. Second, a meta-analysis across all three experiments shows interaction-based process gains in dynamic control tasks: Interacting groups outperform the average individual performance as well as the nominal group performance. Third, group interaction leads to stable individual improvements of group members that exceed practice effects. In sum, these results provide the first unequivocal evidence for interaction-based performance gains of groups in dynamic control tasks and imply that employers should rely on groups to provide opportunities for individual learning and to foster dynamic system control at its best.

    This report describes a Smart Grid concept for how the currently untapped and potentially cheaper resources, i.e. flexible electricity consumption and electricity generation, are put into play through markets or directly where it is economically desirable. The concept provides a framework for how all the actors involved (consumers, power plant owners, BRP, electricity traders, DSO, TSO and other new players) can create increased value solely because a today untapped resource can be activated, namely flexibility in consumption and production from even small consumers. The concept does not attempt to identify all technical needs to operate a market-based power system with 50 % wind power, but the concept focuses on the mobilization of new flexible resources for the benefit of the capacity and voltage challenges in the distribution networks, management of var flow between voltage levels and balance challenge in the power transmission system.

The reader needs to have had an introduction to electrical circuits and AC power, although the text begins with a review of the basics of AC power. Balanced three-phase systems are studied by developing their single-phase equivalents. The study includes a look at how the cost of ""power"" is affected by reactive power and power factor.

    Small group sessions are regarded as a more active and student-centered approach to learning. Item analysis provides objective evidence of whether such sessions improve comprehension and make the topic easier for students, in addition to assessing the relative benefit of the sessions to good versus poor performers. Self-assessment makes students aware of their deficiencies. Small group sessions can also help students develop the ability to self-assess. This study was carried out to assess the effect of small group sessions on item analysis and students' self-assessment. A total of 21 female and 29 male first year medical students participated in a small group session on topics covered by didactic lectures two weeks earlier. It was preceded and followed by two multiple choice question (MCQ) tests, in which students were asked to self-assess their likely score. The MCQs used were item analyzed in a previous group and were chosen of matching difficulty and discriminatory indices for the pre- and post-tests. The small group session improved the marks of both genders equally, but female performance was better. The session made the items easier; increasing the difficulty index significantly but there was no significant alteration in the discriminatory index. There was overestimation in the self-assessment of both genders, but male overestimation was greater. The session improved the self-assessment of students in terms of expected marks and expectation of passing. Small group session improved the ability of students to self-assess their knowledge and increased the difficulty index of items reflecting students' better performance.

    Balancing the subject composition of case and control groups to create homogenous ancestries between each group is essential for medical association studies. We explored the applicability of single-tube 34-plex ancestry informative markers (AIM) single nucleotide polymorphisms (SNPs) to estimate the African Component of Ancestry (ACA) to design a future case-control association study of a Brazilian urban sample. One hundred eighty individuals (107 case group; 73 control group) self-described as white, brown-intermediate or black were selected. The proportions of the relative contribution of a variable number of ancestral population components were similar between case and control groups. Moreover, the case and control groups demonstrated similar distributions for ACA 0.50 categories. Notably a high number of outlier values (23 samples) were observed among individuals with ACA population. This can be achieved using a straight forward multiplexed AIM-SNPs assay of highly discriminatory ancestry markers.

    Full Text Available The participation of the women in the direction of the unions, including Agricultural Workers, has increased in recent years. Until the 80’s, the agricultural syndical movement, specially male, did not accept women associates. Nowadays, women are occupying positions in the executive directory but it does not mean that the unions have changed its pratical discriminatory. This paper presents an analysis concernig gender and power, i.e., a relation between men and women leadership in the west of Santa Catarina State. In spite of improving their participation in the unions and to be established by CUT that 30% of the minimum quota should be women, there are not enough women in the directory positions. They are effectly ocuppying administrative positions or they do not participate equally since the union did not improve its discriminatory participation. It is a frequently war to combine class claims and the search of equality and power gender. Sometimes, they have to choose one claim.

    To establish the discriminatory validity of the mini-mental test (MMSE) and the memory alteration test (M@T) for the diagnosis of amnestic mild cognitive impairment (aMCI) and probable Alzheimer's disease (AD), and also to study the association between the results obtained in screening tests, a neuropsychological battery and a functional questionnaire in healthy persons and in patients with aMCI and AD. We evaluated 27 normal controls, 27 patients with aMCI and 35 patients with AD using the MMSE and a memory screening test, the M@T, a neuropsychological battery and a questionnaire on functional activities of daily living. Pearson correlation coefficients were used to evaluate the relations between the scores on the M@T and the MMSE and the neuropsychological tests. The area below the curve, the sensitivity and the specificity were calculated for the screening tests. In patients with aMCI, the scores on the M@T and the MMSE were strongly associated with the performance in the episodic memory tests in frontal tests and with the scores on the functional questionnaire, but not with tests that evaluated praxias and perceptive functions. In patients with AD, the scores on the M@T and the MMSE were associated with results in semantic memory, language, executive functions and praxias, but not with perceptive tests and functional questionnaires. In patients with aMCI and AD, the association between MMSE and M@T only correlate with some cognitive functions, without there being any association with other cognitive functions. Therefore, screening tests cannot be used as the only instrument for evaluating the cognitive status in patients with suspected dementia.

  20. Culture and concepts of power.

    Torelli, Carlos J; Shavitt, Sharon

    2010-10-01

    Five studies indicate that conceptualizations of power are important elements of culture and serve culturally relevant goals. These studies provide converging evidence that cultures nurture different views of what is desirable and meaningful to do with power. Vertical individualism is associated with a conceptualization of power in personalized terms (i.e., power is for advancing one's personal status and prestige), whereas horizontal collectivism is associated with a conceptualization of power in socialized terms (i.e., power is for benefiting and helping others). Cultural variables are shown to predict beliefs about appropriate uses of power, episodic memories about power, attitudes in the service of power goals, and the contexts and ways in which power is used and defended. Evidence for the cultural patterning of power concepts is observed at both the individual level and the cultural-group level of analysis.

    The authors presents an introduction to quantum groups defined as a deformation of the universal enveloping algebra of a Lie algebra. After the description of Hopf algebras with some examples the approach of Drinfel'd and Jimbo is described, where the quantization of a Lie algebra represents a Hopf algebra, defined over the algebra of formal power series in an indetermined h. The authors show that this approach arises from a r-matrix, which satisfies the classical Yang-Baxter equation. As example quantum sl 2 is considered. Furthermore the approaches of Manin and Woroniwicz and the R-matrix approach are described. (HSI)

  12. Estimating the concordance probability in a survival analysis with a discrete number of risk groups.

    Science.gov (United States)

    Heller, Glenn; Mo, Qianxing

    2016-04-01

    A clinical risk classification system is an important component of a treatment decision algorithm. A measure used to assess the strength of a risk classification system is discrimination, and when the outcome is survival time, the most commonly applied global measure of discrimination is the concordance probability. The concordance probability represents the pairwise probability of lower patient risk given longer survival time. The c-index and the concordance probability estimate have been used to estimate the concordance probability when patient-specific risk scores are continuous. In the current paper, the concordance probability estimate and an inverse probability censoring weighted c-index are modified to account for discrete risk scores. Simulations are generated to assess the finite sample properties of the concordance probability estimate and the weighted c-index. An application of these measures of discriminatory power to a metastatic prostate cancer risk classification system is examined.

    The objective of this study is to examine factors and prospects for a resumption in growth of nuclear power in the United States over the next decade. The focus of analysis on the likelihood that current efforts in the United States to develop improved and safer nuclear power reactors will provide a sound technical basis for improved acceptance of nuclear power, and contribute to a social/political climate more conducive to a resumption of nuclear power growth. The acceptability of nuclear power and advanced reactors to five social/political sectors in the U.S. is examined. Three sectors highly relevant to the prospects for a restart of nuclear power plant construction are the financial sector involved in financing nuclear power plant construction, the federal nuclear regulatory sector, and the national political sector. For this analysis, the general public are divided into two groups: those who are knowledgeable about and involved in nuclear power issues, the involved public, and the much larger body of the general public that is relatively uninvolved in the controversy over nuclear power

    Nuclear reactors have provided energy for satellites-with nearly disastrous results. Now the US government is proposing to build nuclear-powered boosters to launch Star Wars defenses. These authors represent scientific groups that are opposed to the use of nuclear power in near space. The authors feel that the best course for space-borne reactors is to ban them from Earth orbit and use them in deep space

    Full Text Available Vitamin C stability and concentration was evaluated in isotonic beverages and B group vitamins (B1, B2, B3, B5 and B6 in power beverages. The amount of vitamins was found to be above of that declared on the labels, even after the shelf life had been exceeded. A small decrease in the amount of B group vitamins was observed during the shelf life of the products. In the case of vitamin C this decrease was slightly higher. The present research shows the need of increased quality control and inspection.

    Over the past ten years, the hoped for growth of an international air conditioning market fueled by natural gas, has not lived up to expectations. The purpose of this report is to assess causal factors and to pinpoint any key areas for corrective action, if our successes are to be enhanced. We started by evaluating the conditions in the Japanese market that allowed for the most successful penetration of the gas cooling market in the world, and then built a model that describes those conditions. Next we examined the market criteria and constructed models for two cities in the U.S., and for France and Spain, and then compared the results against the Japanese model. Biogas is the name given to a gas mixture with high methane content resulting from the bacteriological fermentation of organic material in an anaerobic environment. In addition to combustible methane gas, the mixture contains carbon dioxide, water and lesser amounts of other components. Today, there is an increased demand in some of the worlds' markets for environmentally friendly and sustainable energy systems. The fact that biogas is just as clean as natural gas and is renewable can be used by the natural gas industry in their efforts to increase gas demand. As natural gas can benefit from biogas, biogas can also benefit from natural gas. Biogas needs the support of the resources of the natural gas industry, such as infrastructure, marketing and research to become one, albeit small, part of our energy supply. IGU SG 6.2 presents in this paper a short description of the possible uses of biogas, a description of the biogas process, the different technologies for production, cleaning and upgrading biogas to natural gas quality, and some of the marketing concepts that have been successfully employed. A world-wide trend towards decentralized power generation is being observed in those countries where electricity is generated in centralized fossil-fuelled power stations. This is due to a variety of

  8. Monte Carlo simulations on marker grouping and ordering.

    Four global algorithms, maximum likelihood (ML), sum of adjacent LOD score (SALOD), sum of adjacent recombinant fractions (SARF) and product of adjacent recombinant fraction (PARF), and one approximation algorithm, seriation (SER), were used to compare the marker ordering efficiencies for correctly given linkage groups based on doubled haploid (DH) populations. The Monte Carlo simulation results indicated the marker ordering powers for the five methods were almost identical. High correlation coefficients were greater than 0.99 between grouping power and ordering power, indicating that all these methods for marker ordering were reliable. Therefore, the main problem for linkage analysis was how to improve the grouping power. Since the SER approach provided the advantage of speed without losing ordering power, this approach was used for detailed simulations. For more generality, multiple linkage groups were employed, and population size, linkage cutoff criterion, marker spacing pattern (even or uneven), and marker spacing distance (close or loose) were considered for obtaining acceptable grouping powers. Simulation results indicated that the grouping power was related to population size, marker spacing distance, and cutoff criterion. Generally, a large population size provided higher grouping power than small population size, and closely linked markers provided higher grouping power than loosely linked markers. The cutoff criterion range for achieving acceptable grouping power and ordering power differed for varying cases; however, combining all situations in this study, a cutoff criterion ranging from 50 cM to 60 cM was recommended for achieving acceptable grouping power and ordering power for different cases.

  12. Geometric group theory an introduction

    Löh, Clara

    2017-01-01

    Inspired by classical geometry, geometric group theory has in turn provided a variety of applications to geometry, topology, group theory, number theory and graph theory. This carefully written textbook provides a rigorous introduction to this rapidly evolving field whose methods have proven to be powerful tools in neighbouring fields such as geometric topology. Geometric group theory is the study of finitely generated groups via the geometry of their associated Cayley graphs. It turns out that the essence of the geometry of such groups is captured in the key notion of quasi-isometry, a large-scale version of isometry whose invariants include growth types, curvature conditions, boundary constructions, and amenability. This book covers the foundations of quasi-geometry of groups at an advanced undergraduate level. The subject is illustrated by many elementary examples, outlooks on applications, as well as an extensive collection of exercises.

    1990-01-01

    Written from the basis of neutrality, neither for nor against nuclear power this book considers whether there are special features of nuclear power which mean that its development should be either promoted or restrained by the State. The author makes it dear that there are no easy answers to the questions raised by the intervention of nuclear power but calls for openness in the nuclear decision making process. First, the need for energy is considered; most people agree that energy is the power to progress. Then the historicalzed background to the current position of nuclear power is given. Further chapters consider the fuel cycle, environmental impacts including carbon dioxide emission and the greenhouse effect, the costs, safety and risks and waste disposal. No conclusion either for or against nuclear power is made. The various shades of opinion are outlined and the arguments presented so that readers can come to their own conclusions. (UK)

    Renormalization groups used in diverse fields of theoretical physics are considered. The discussion is based upon functional formulation of group transformations. This attitude enables development of a general method by using the notion of functional self-similarity which generalizes the usual self-similarity connected with power similarity laws. From this point of view the authors present a simple derivation of the renorm-group (RG) in QFT liberated from ultra-violet divergences philosophy, discuss the RG approach in other fields of physics and compare different RG's

  5. Measurement of Glycosylated Alpha-Fetoprotein Improves Diagnostic Power over the Native Form in Hepatocellular Carcinoma

    2014-01-01

    Serum alpha-fetoprotein (AFP) has long been used as a diagnostic marker for hepatocellular carcinoma (HCC), albeit controversially. Although it remains widely used in clinics, the value of AFP in HCC diagnosis has recently been challenged due to its significant rates of false positive and false negative findings. To improve the efficacy of AFP as HCC diagnostic marker, we developed a method of measuring total and glycosylated AFP by multiple reaction monitoring (MRM)-MS. In this study, we verified the total amount of AFP (nonglycopeptide levels) and the degree of glycosylated AFP (deglycopeptide levels) in 60 normal (41 men and 19 women; mean age 53 years; range 32–74 years), 35 LC (23 men and 12 women; mean age 56 years; range 43–78 years; HBV-related), and 60 HCC subjects (42 men and 18 women; mean age 58 years; range 38–76 years; HBV-related; 30 stage I, 15 stage II, and 10 stage III). By MRM-MS analysis, the nonglycopeptide had 56.7% sensitivity, 68.3% specificity, and an AUC of 0.687 [cutoff value: ≥0.02 (light/heavy ratio)], comparing the normal and HCC group, whereas the deglycopeptide had 93.3% sensitivity, 68.3% specificity, and an AUC of 0.859 [cutoff value: ≥0.02 (light/heavy ratio)]. In comparing the stage I HCC subgroup with the LC group, the nonglycopeptide had a sensitivity of 66.7%, specificity of 80.0%, and an AUC of 0.712 [cutoff value: ≥0.02 (light/heavy ratio)], whereas the deglycopeptide had a sensitivity of 96.7%, specificity of 80.0%, and an AUC of 0.918 [cutoff value: ≥0.02 (light/heavy ratio)]. These data demonstrate that the discriminatory power of the deglycopeptide is greater than that of the nonglycopeptide. We conclude that deglycopeptide can distinguish cancer status between normal subjects and HCC patients better than nonglycopeptide. PMID:25310463

    The key element of our pulsed power program is concentration of power in time and space by suppression of breakdown in dielectrics and in vacuum. Magnetically insulated vacuum transmission lines and magnetic suppression of insulator flashover have continued as the main reserch directions. Vacuum insulated line studies at Physics International have been expanded and a test bed at Sandia, called MITE (Magnetically Insulated Transmission Experiment), is under development. The choice for the baseline EBFA design will depend on the outcome of these studies and should be made in July 1977. The slow and intermediate speed pulsed power approaches to EBFA will be based on Proto I and Proto II results and several of the projected EBFA subsystems are presently being tested in Proto II. A further stage of power concentration, within the vacuum diode itself, would considerably ease the burden on dielectrics; methods of power multiplication involving magnetically imploded plasmas are being considered and tests have begun using the Ripple III apparatus

The task group's report states that from the power industry's perspective, there is no reason to modify the existing system created by sections 103, 103a of the GWB. The EC internal market to come, and enhanced use of coal for power generation to be continued beyond the year 1995 are topics that will keep politicians, utilities, and lawmakers in this field busy enough.

    The committee concludes that the nature of the proliferation problem is such that even stopping nuclear power completely could not stop proliferation completely. Countries can acquire nuclear weapons by means independent of commercial nuclear power. It is reasonable to suppose if a country is strongly motivated to acquire nuclear weapons, it will have them by 2010, or soon thereafter, no matter how nuclear power is managed in the meantime. Unilateral and international diplomatic measures to reduce the motivations that lead to proliferation should be high on the foreign policy agenda of the United States. A mimimum antiproliferation prescription for the management of nuclear power is to try to raise the political barriers against proliferation through misuse of nuclear power by strengthening the Non-Proliferation Treaty, and to seek to raise the technological barriers by placing fuel-cycle operations involving weapons-usable material under international control. Any such measures should be considered tactics to slow the spread of nuclear weapons and thus earn time for the exercise of statesmanship. The committee concludes the following about technical factors that should be considered in formulating nuclear policy: (1) rate of growth of electricity use is a primary factor; (2) growth of conventional nuclear power will be limited by producibility of domestic uranium sources; (3) greater contribution of nuclear power beyond 400 GWe past the year 2000 can only be supported by advanced reactor systems; and (4) several different breeder reactors could serve in principle as candidates for an indefinitely sustainable source of energy

    In the second half of twentieth century, nuclear power became an industrial reality. Now the operating 433 power plants, the 37 plants under construction, near 9000 years/reactor with only one serious accident with emission of radioactive material to the environment (Chernobyl) show the maturity of this technology. Today nuclear power contribute a 17% to the global generation and an increase of 75 % of the demand of electricity is estimated for 2020 while this demand is expected to triplicate by 2050. How this requirement can be satisfied? All the indicators seems to demonstrate that nuclear power will be the solution because of the shortage of other sources, the increase of the prices of the non renewable fuels and the scarce contribution of the renewable ones. In addition, the climatic changes produced by the greenhouse effect make even more attractive nuclear power. The situation of Argentina is analyzed and compared with other countries. The convenience of an increase of nuclear power contribution to the total national generation seems clear and the conclusion of the construction of the Atucha II nuclear power plant is recommended

    As the implementation of the national guideline of 'proactively promoting nuclear power development', especially after China decided in 2006 to introduce Westinghouse's AP1000 technology, some of the power groups specialized in conventional power generation, have been participating in the preliminary work and construction of nuclear power projects in certain degrees. Meanwhile, such traditional nuclear power corporations as China National Nuclear Corporation (CNNC) and China Guangdong Nuclear Power Corporation (CGNPC) have also employed some employees with conventional power generation experience. How can these employees who have long been engaged in conventional power generation successfully adapt to the new work pattern, ideology, knowledge, thinking mode and proficiency of nuclear power, so that they can fit in with the work requirements of nuclear power and become qualified as soon as possible? By analyzing the technological, managerial and cultural features of nuclear power, as well as some issues to be kept in mind when engaged in nuclear power, this paper intends to make some contribution to the nuclear power development in the specific period.

This analysis reveals some frequently overlooked truths about the current state of nuclear technology: An examination of the issues also produces some noteworthy insights concerning government regulations and related technologies. Public opinion will play a major role in the unfolding story of the nuclear power renaissance. Some observers are betting that psychological, sociological, and political considerations will hod sway over public attitudes. Others wager that economic and technical concerns will prevail. The implications for the nuclear power renaissance are striking

    Two experiments explored the relations between prejudice (suppression), (cognitive) ambivalence and negative behavioural tendencies towards out-groups. The current work argues that expressing out-group ambivalence based on cognitive, but not affective, information is a strategy to justify one's otherwise suppressed prejudice, which may ultimately "cover" the discriminatory nature of out-group-directed negative behavioural tendencies. Two experiments show that (1) participants evaluating the out-group in a normative context inducing prejudice suppression are more likely to self-report ambivalent beliefs rather than ambivalent emotions concerning the out-group as compared with participants whose prejudice expression is induced and (2) high-prejudice participants compared with low-prejudice participants are more prone to out-group-directed negative behavioural tendencies when these latter are self-reported after the expression of ambivalent beliefs but not ambivalent emotions concerning the out-group, and when the expression of their prejudicial evaluations is salient but not when it is not. In light of the extent to which ambivalent attitudes towards out-groups are often seamlessly integrated into public discourse, the implications of the findings are discussed not only for intergroup research but also at the societal level.

    The object is to provide a method of operating a dual purpose power station so that the steam supply system is operated at a high load factor. The available steam not required for electricity generation is used to provide process heat and the new feature is that the process plant capacity is determined to make the most economic use of the steam supply system, and not to match the passout capacity of the turbine of the turbogenerator. The product of the process plant should, therefore, be capable of being stored. A dual-purpose power station with a nuclear-powered steam source, turbogenerating means connected to the steam source and steam-powered process plant susceptible to wide variation in its rate of operation is described.

    Over the course of childhood, children's thinking about social groups changes in a variety of ways. Developmental Subjective Group Dynamics (DSGD) theory emphasizes children's understanding of the importance of conforming to group norms. Abrams et al.'s study, which uses DSGD theory as a framework, demonstrates the social cognitive skills underlying young elementary school children's thinking about group norms. Future research on children's thinking about groups and group norms should explore additional elements of this topic, including aspects of typicality beyond loyalty. © 2014 The British Psychological Society.

    1988-09-01

    Lattice gauge theory, formulated in terms of invariant integrals over group elements on lattice bonds, benefits from many group theoretical notions. Gauge invariance provides an enormous symmetry and powerful constraints on expectation values. Strong coupling expansions require invariant integrals over polynomials in group elements, all of which can be evaluated by symmetry considerations. Numerical simulations involve random walks over the group. These walks automatically generate the invariant group measure, avoiding explicit parameterization. A recently proposed overrelaxation algorithm is particularly efficient at exploring the group manifold. These and other applications of group theory to lattice gauge fields are reviewed in this talk. 17 refs

    In the classic discriminant model of two multivariate normal distributions with equal variance matrices, the linear discriminant function is optimal both in terms of the log likelihood ratio and in terms of maximizing the standardized difference (the t-statistic) between the means of the two distributions. In a typical case-control study, normality may be sensible for the control sample but heterogeneity and uncertainty in diagnosis may suggest that a more flexible model is needed for the cases. We generalize the t-statistic approach by finding the linear function which maximizes a standardized difference but with data from one of the groups (the cases) filtered by a possibly nonlinear function U. We study conditions for consistency of the method and find the function U which is optimal in the sense of asymptotic efficiency. Optimality may also extend to other measures of discriminatory efficiency such as the area under the receiver operating characteristic curve. The optimal function U depends on a scalar probability density function which can be estimated non-parametrically using a standard numerical algorithm. A lasso-like version for variable selection is implemented by adding L1-regularization to the generalized t-statistic. Two microarray data sets in the study of asthma and various cancers are used as motivating examples. © 2014, The International Biometric Society.

    The main objective of the effluent treatment is to correct its undesirable characteristics, however, during this process, residues like sludge and biogas are generated, and those residues can be used as raw materials. The PUREFA (Program of Rational Energy Use and Alternative Sources), compound by 14 purposes, is about a project of the USP - University of Sao Paulo, financial backer FINEP - Financier of Studies and Projects. This project had three main objectives: to implant measures of management and action of energy efficiency, to increase the distributed generation in the USP from the renewable resource and not conventional energy and to introduce incentive permanent politics to the efficient and rational use of energy. In the context, the Brazilian Reference Center on Biomass was responsible for two purposes, related to the biogas use for electricity generation. The first purpose had main objective to implant the generation system, to capture and to stock the biogas, produced by biodigestor in the Technological Hydraulically Center (CTH - USP). The biodigestor is a UASB (Upflow Anaerobic Sludge Blanket), whose outflow of the biogas produce is near 4 m{sup 3}/day, opera rates 24 hours per day and utilize the sewer from the residential buildings located in Sao Paulo University, inside the campus. For the biogas utilization, was made its outflow, chemical composition and heat value identifications, parameters that allowed to determinate the real potential for generation and to shown the necessity of the previous treatment, as H2S removal. Finished this stage, was started the next purpose, regarding biogas used as fuel for electricity generation using a generator group Otto cycle. Nowadays this project is a demonstrative project. In this article the technical and environmental project results obtained will be presented. (author)

    The Radiation Sources Working Group addressed advanced concepts for the generation of RF energy to power advanced accelerators. The focus of the working group included advanced sources and technologies above 17 GHz. The topics discussed included RF sources above 17 GHz, pulse compression techniques to achieve extreme peak power levels, components technology, technology limitations and physical limits, and other advanced concepts. RF sources included gyroklystrons, magnicons, free-electron masers, two beam accelerators, and gyroharmonic and traveling wave devices. Technology components discussed included advanced cathodes and electron guns, high temperature superconductors for producing magnetic fields, RF breakdown physics and mitigation, and phenomena that impact source design such as fatigue in resonant structures due to RF heating. New approaches for RF source diagnostics located internal to the source were discussed for detecting plasma and beam phenomena existing in high energy density electrodynamic systems in order to help elucidate the reasons for performance limitations

    Gipe, P.

    2007-01-01

    This book is a translation of the edition published in the USA under the title of ''wind power: renewable energy for home, farm and business''. In the wake of mass blackouts and energy crises, wind power remains a largely untapped resource of renewable energy. It is a booming worldwide industry whose technology, under the collective wing of aficionados like author Paul Gipe, is coming of age. Wind Power guides us through the emergent, sometimes daunting discourse on wind technology, giving frank explanations of how to use wind technology wisely and sound advice on how to avoid common mistakes. Since the mid-1970's, Paul Gipe has played a part in nearly every aspect of wind energy development from installing small turbines to promoting wind energy worldwide. As an American proponent of renewable energy, Gipe has earned the acclaim and respect of European energy specialists for years, but his arguments have often fallen on deaf ears at home. Today, the topic of wind power is cropping up everywhere from the beaches of Cape Cod to the Oregon-Washington border, and one wind turbine is capable of producing enough electricity per year to run 200 average American households. Now, Paul Gipe is back to shed light on this increasingly important energy source with a revised edition of Wind Power. Over the course of his career, Paul Gipe has been a proponent, participant, observer, and critic of the wind industry. His experience with wind has given rise to two previous books on the subject, Wind Energy Basics and Wind Power for Home and Business, which have sold over 50,000 copies. Wind Power for Home and Business has become a staple for both homeowners and professionals interested in the subject, and now, with energy prices soaring, interest in wind power is hitting an all-time high. With chapters on output and economics, Wind Power discloses how much you can expect from each method of wind technology, both in terms of energy and financial savings. The book updated models

    In Japan, as the Rule on Electric Business was revised after an interval of 35 years in 1995, and a competitive bid on new electric source was adopted after 1996 fiscal year, investigation on further competition introduction to electric power market was begun by establishment of the Basic Group of the Electric Business Council in 1997. By a report proposed on January, 1999 by the Group, the Rule was revised again on March, 1999 to start a partial liberation or retail of the electric power from March, 2000. From a viewpoint of energy security and for solution of global environmental problem in Japan it has been decided to positively promote nuclear power in future. Therefore, it is necessary to investigate how the competition introduction affects to development of nuclear power generation and what is a market liberation model capable of harmonizing with the development on liberation of electric power market. Here was elucidated on effect of the introduction on previous and future nuclear power generation, after introducing new aspects of nuclear power problems and investigating characteristic points and investment risks specific to the nuclear power generation. And, by investigating some possibilities to development of nuclear power generation under liberation models of each market, an implication was shown on how to be future liberation on electric power market in Japan.

    The preparation of Country Nuclear Power Profiles was initiated within the framework of the IAEA`s programme for nuclear power plant performance assessment and feedback. It responded to a need for a database and a technical document containing a description of the energy and economic situation and the primary organizations involved in nuclear power in IAEA Member States. The task was included in the IAEA`s programmes for 1993/1994 and 1995/1996. In March 1993, the IAEA organized a Technical Committee meeting to discuss the establishment of country data ``profiles``, to define the information to be included in the profiles and to review the information already available in the IAEA. Two expert meetings were convened in November 1994 to provide guidance to the IAEA on the establishment of the country nuclear profiles, on the structure and content of the profiles, and on the preparation of the publication and the electronic database. In June 1995, an Advisory Group meeting provided the IAEA with comprehensive guidance on the establishment and dissemination of an information package on industrial and organizational aspects of nuclear power to be included in the profiles. The group of experts recommended that the profiles focus on the overall economic, energy and electricity situation in the country and on its nuclear power industrial structure and organizational framework. In its first release, the compilation would cover all countries with operating power plants by the end of 1995. It was also recommended to further promote information exchange on the lessons learned from the countries engaged in nuclear programmes. For the preparation of this publication, the IAEA received contributions from the 29 countries operating nuclear power plants and Italy. A database has been implemented and the profiles are supporting programmatic needs within the IAEA; it is expected that the database will be publicly accessible in the future. Refs, figs, tabs.

    We map for the first time the two-dimensional H{sub 2} excitation of warm intergalactic gas in Stephan's Quintet on group-wide (50 × 35 kpc{sup 2}) scales to quantify the temperature, mass, and warm H{sub 2} mass fraction as a function of position using Spitzer . Molecular gas temperatures are seen to rise (to T > 700 K) and the slope of the power-law density–temperature relation flattens along the main ridge of the filament, defining the region of maximum heating. We also performed MHD modeling of the excitation properties of the warm gas, to map the velocity structure and energy deposition rate of slow and fast molecular shocks. Slow magnetic shocks were required to explain the power radiated from the lowest-lying rotational states of H{sub 2}, and strongly support the idea that energy cascades down to small scales and low velocities from the fast collision of NGC 7318b with group-wide gas. The highest levels of heating of the warm H{sub 2} are strongly correlated with the large-scale stirring of the medium as measured by [C ii] spectroscopy with Herschel . H{sub 2} is also seen associated with a separate bridge that extends toward the Seyfert nucleus in NGC 7319, from both Spitzer and CARMA CO observations. This opens up the possibility that both galaxy collisions and outflows from active galactic nuclei can turbulently heat gas on large scales in compact groups. The observations provide a laboratory for studying the effects of turbulent energy dissipation on group-wide scales, which may provide clues about the heating and cooling of gas at high z in early galaxy and protogalaxy formation.

    Describes the organisation of the Malaysian electric power industry and the role of natural gas and coal in power generation in the country. At present, electricity is produced by three utilities: Tenaga Nasional Berhad (TNB) which was fully privatised in May 1992 with the Government holding about 73% of the equity, Sarawak Electricity Supply Corporation (SESCO) which the Government plans to privatise soon, and Sabah Electricity Board (SEB). These have installed capacities of 7000 MW, 400 MW and 350 MW, respectively. Five independent power producers have been given licences to build, own and operate power plants with a total installed capacity of 4000 MW. Natural gas is expected to account for about 72% of Malaysia's power generating fuel by the year 2010, compared to about 50% at present. Malaysia currently has only one coal-fired plant, but its expansion is in the final stage of contract awards. A number of small capacity coal-fired plants are being planned for Sabah and Sarawak where the bulk of Malaysia's coal resources are located. 3 figs., 1 photo.

    Full Text Available This is an introduction to finite simple groups, in particular sporadic groups, intended for physicists. After a short review of group theory, we enumerate the 1+1+16=18 families of finite simple groups, as an introduction to the sporadic groups. These are described next, in three levels of increasing complexity, plus the six isolated ''pariah'' groups. The (old five Mathieu groups make up the first, smallest order level. The seven groups related to the Leech lattice, including the three Conway groups, constitute the second level. The third and highest level contains the Monster group M, plus seven other related groups. Next a brief mention is made of the remaining six pariah groups, thus completing the 5+7+8+6=26 sporadic groups. The review ends up with a brief discussion of a few of physical applications of finite groups in physics, including a couple of recent examples which use sporadic groups.

    To describe and get a deeper understanding of how groups of young women and men reflect on and discuss pornography and its spread in the media and society, and its possible influence on sexual behaviour and relationships. Six focus group interviews were conducted with teenagers, three with women (n = 17) and three with men (n = 18). Open questions about pornography and its spread in the media and society were discussed. The interviews were tape-recorded and transcribed verbatim. Data were analysed according to Grounded Theory. The core category 'A discriminatory sexuality' illustrates how participants felt regarding the messages conveyed by pornography portraying a man's role as dominant and a woman's role as subordinate. Pornographic messages were described as 'Fiction' depicting a distorted reality. Feelings of ambivalence towards pornography were expressed: anxiety and fear, but also inspiration. Participants said pornography occurred everywhere in the media and society, and felt pressured by messages relating to looks and sexual techniques. Pornography and its spread in the media and society were considered as presenting a discriminatory image of body ideals, sexuality and relationships. Despite this awareness, both men and women considered pornography as sources of knowledge and inspiration: an apparent paradox.

    This presentation described Plug Power's GenDrive hydrogen fuel cell unit that supplies the power needs for folk lift trucks used in high-throughput distribution and high-volume manufacturing operations. The system offers an alternative to lead acid batteries, providing maximum performance at all times during use. The system is particularly useful in the material handling industry, where the revenue generated is based on operator uptime and lift truck productivity. The use of the system allows customers to reduce operational costs and expand valuable floor space by eliminating batteries and associated recharging infrastructure. Fuel cell units also reduce the wear on truck motors. Truck operators can easily and safely refuel at hydrogen fueling stations in 1-5 minutes. GenDrive works with all major OEM lift trucks, making the transition seamless. Commercial customers are investing in this solution to improve their current operations. In 2008, Plug Power sold to Wal-Mart, Bridgestone Firestone and Nestle. Most notably, Central Grocers purchased 220 fuel cell units for a new greenfield distribution center. Plug Power currently has more than 380 systems in operation.

    Ethnic group discrimination represents a notable risk factor that may contribute to mental health problems among ethnic minority college students. However, cultural resources (e.g., ethnic identity) may promote psychological adjustment in the context of group-based discriminatory experiences. In the current study, we examined the associations between perceptions of ethnic group discrimination and depressive symptoms, and explored dimensions of ethnic identity (i.e., exploration, resolution, and affirmation) as mediators of this process among 2,315 ethnic minority college students (age 18 to 30 years; 37% Black, 63% Latino). Results indicated that perceived ethnic group discrimination was associated positively with depressive symptoms among students from both ethnic groups. The relationship between perceived ethnic group discrimination and depressive symptoms was mediated by ethnic identity affirmation for Latino students, but not for Black students. Ethnic identity resolution was negatively and indirectly associated with depressive symptoms through ethnic identity affirmation for both Black and Latino students. Implications for promoting ethnic minority college students' mental health and directions for future research are discussed. (PsycINFO Database Record (c) 2015 APA, all rights reserved).

    Full text: In 1997 and as a result of political developments in the Dutch government's energy policy, the Nuclear Power Plant (NPP) Dodewaard was forced to stop producing electricity for the national grid. As a consequence, plans for the decommissioning of the NPP were developed. For the Netherlands this is a first-of-a-kind project: so far no nuclear installation has been actually dismantled in this country. GKN, the operator of NPP Dodewaard, started a vast decommissioning project. Four years elapsed before a concept was ready for the licence required to carry out the plans. The scope of activities is as follows. Once all spent fuel has been removed from the site the installation will be brought into a state of so-called Safe Enclosure, which will ensure that all radioactivity remaining inside components and buildings, can be kept safely locked in for a period of 40 years. At the end of this 40 year waiting period, when radiation levels will have dropped considerably in a natural way, the NPP will be dismantled and the grounds on which the complex was built can return to be the green meadow-land they once were. The process of convincing the Dutch government and obtaining approval for these plans took a lot of time and effort from GKN's side. Now - almost five years later - we have reached the stage that the text of the concept licence has been made public to the Dutch citizens who, within a defined period of time, may submit any objections they have, prior to the licence becoming final. In the Netherlands a majority of the people are not exactly enthusiastic about nuclear. Therefore, PR matters related to the Dodewaard NPP are mostly been handled low-key and in a reactive way rather than pro-actively. But with respect to the plans for the future of the Dodewaard plant, operator GKN felt a distinct obligation to inform in a timely and active manner both our government as well as the man in the street. With that objective in mind, we decided to develop an in

  14. Competitive electric power markets and grid reliability : something has changed during the past decade

    This white paper reviewed some of the fundamental changes in the way in which electricity is provided to customers. Previously, electricity was delivered by integrated electric utilities that owned both generation and transmission and directly served their customers. Restructuring altered the rules that govern control, operation, ownership and regulation of the industry. The traditional integrated utility has been disaggregated. Wholesale electricity costs are no longer regulated and prices are now set by supply and demand in a market context. Generation investment decisions are based on future expectations of market performance. It was suggested that transmission should become a facilitator of the competitive market. Inter-ties are an essential part of a competitive market, as a means to import power when needed and to export surplus energy. The role of transmission in facilitating new generation by providing non-discriminatory and efficient transport to the market was discussed. It was noted that the lack of transmission investment is resulting in economic penalties, rising losses and constraints on more economic generators. Transmission congestion is counterproductive to the interests of customers. A move away from regional planning to a recognition of the wider interconnectedness of the system was recommended. The current practice of deferring necessary maintenance as a way to generate short-term profit was examined. It was noted that despite the need for new transmission infrastructure, investment in merchant alternating current projects has been slow to materialize. Other challenges to transmission included the uncertainty of regulatory processes and investment recovery as well as the unpredictability of flow patterns in the bulk power system. It was concluded that competitive generation markets will not work with an inadequate transmission infrastructure. Transmission enables new generation by ensuring non-discriminatory and efficient transport to market

    Evaluations of patients with pulmonary hypertension (PH) commonly include chest CT imaging. We hypothesized that cardiac chamber volumes calculated from the same CT scans can yield additional information to distinguish PH related to left-sided heart disease (World Health Organization group 2) from other PH subtypes. Patients who had PH confirmed by right heart catheterization and contrast-enhanced chest CT studies were enrolled in this retrospective multicenter study. Cardiac chamber volumes were calculated using automated segmentation software and compared between group 2 and non-group 2 patients with PH. This study included 114 patients with PH, 27 (24%) of whom were classified as group 2 based on their pulmonary capillary wedge pressure. Patients with group 2 PH exhibited significantly larger median left atrial (LA) volumes (118 mL vs 63 mL; P volumes (90 mL vs 76 mL; P = .02), and smaller median right ventricular (RV) volumes (173 mL vs 210 mL; P = .005) than did non-group 2 patients. On multivariate analysis adjusted for age, sex, and mean pulmonary arterial pressure, group 2 PH was significantly associated with larger median LA and LV volumes (P volume ratios of RA/LA, RV/LV, and RV/LA (P = .001, P = .004, and P volumes demonstrated a high discriminatory ability for group 2 PH (area under the curve, 0.92; 95% CI, 0.870-0.968). Volumetric analysis of the cardiac chambers from nongated chest CT scans, particularly with findings of an enlarged left atrium, exhibited high discriminatory ability for identifying patients with PH due to left-sided heart disease.

    This study was conducted to check and see, using Hayashi's quantification method III, whether or not the respondents differed in their images of a nuclear power plant, depending on their demographic variables particularly occupations. In our simple tabulation, we compared subject groups of nuclear power plant employees with general citizens, nurses and students in terms of their images of a nuclear power plant. The results were that while the nuclear power plant employees were high in their evaluations of facts about a nuclear power plant and in their positive images of a nuclear power plant, general citizens, nurses and students were overwhelmingly high in their negative images of a nuclear power plant. In our analysis on category score by means of the quantification method III, the first correlation axis was the dimension of 'safety'-'danger' and the second correlation axis was the dimension of 'subjectivity'-'objectivity', and that the first quadrant was the area of 'safety-subjectivity', the second quadrant was the area of 'danger-subjectivity', the third quadrant as the area of 'danger-objectivity', and the forth quadrant was the area of 'safety-objectivity'. In our analysis of sample score, 16 occupation groups was compared. As a result, it was found that the 16 occupation groups' images of a nuclear power plant were, in the order of favorableness, (1) section chiefs in charge, maintenance subsection chiefs, maintenance foremen, (2) field leaders from subcontractors, (3) maintenance section members, operation section members, (4) employees of those subcontractors, (5) general citizens, nurses and students. On the 'safety-danger' dimension, nuclear power plant workers on the one hand and general citizens, nurses and students on the other were clearly divided in terms of their images of a nuclear power plant. Nuclear power plant workers were concentrated in the area of 'safety' and general citizens, nurses and students in the area of 'danger'. (J.P.N.)

    Milestones of electrical power development in Switzerland during 1982 are quoted. An energy balance is shown for the utilisation of 864,630 terajoules of primary energy. This is related to global data on per capita power consumption. In the electricity generation section, annual load factors are given for the four nuclear stations. A brief review is made of hydro potential and monthly export/import figures for power to other countries (mostly export, especially in summer). Total electrical power output grew about 1.3% in the last year. Recent transmission line developments are noted, mostly 2x380kV, and including a link with Austria. In the financial section, consumer price indices are quoted for liquid and solid fuel, gas and electricity since 1966. Under administration, details are listed of the main and about 18 supporting Committees and working groups with special functions (e.g. tariffs, electrical vehicles). Public relations have included nuclear power press conferences, a mobile video unit, information leaflets for the media and a teaching seminar. (G.C.)

  3. The nuclear power decisions

    International Nuclear Information System (INIS)

    Williams, R.

    1980-01-01

    Nuclear power has now become highly controversial and there is violent disagreement about how far this technology can and should contribute to the Western energy economy. More so than any other energy resource, nuclear power has the capacity to provide much of our energy needs but the risk is now seen to be very large indeed. This book discusses the major British decisions in the civil nuclear field, and the way they were made, between 1953 and 1978. That is, it spans the period between the decision to construct Calder Hall - claimed as the world's first nuclear power station - and the Windscale Inquiry - claimed as the world's most thorough study of a nuclear project. For the period up to 1974 this involves a study of the internal processes of British central government - what the author terms 'private' politics to distinguish them from the very 'public' or open politics which have characterised the period since 1974. The private issues include the technical selection of nuclear reactors, the economic arguments about nuclear power and the political clashes between institutions and individuals. The public issues concern nuclear safety and the environment and the rights and opportunities for individuals and groups to protest about nuclear development. The book demonstrates that British civil nuclear power decision making has had many shortcomings and concludes that it was hampered by outdated political and administrative attitudes and machinery and that some of the central issues in the nuclear debate were misunderstood by the decision makers themselves.

    The question 'Do we really need nuclear power' is tackled within the context of Christian beliefs. First, an estimate is made of the energy requirements in the future and whether it can be got in conventional ways. The dangers of all the ways of supplying energy (eg coal mining, oil and gas production) are considered scientifically. Also the cost of each source and its environmental effects are debated. The consequences of developing a new energy source, as well as the consequences of not developing it, are considered. Decisions must also take into account a belief about the ultimate purpose of life, the relation of men to each other and to nature. Each issue is raised and questions for discussion are posed. On the whole the book comes down in favour of nuclear power.

    Options for EBFA-I were narrowed as data became available from Proto II, MITE and power flow research. The solid dielectric capacitors proposed for intermediate stores have been eliminated for EBFA because of low reliability. Water capacitors based on data from Proto II and Hydra will be used on EBFA. Improved SF-6 switching data from Proto II shows that present parameters are adequate for EBFA. A switch jitter of 3 ns with reliability exceeding 0.986 was demonstrated. Proto II has achieved the design output and is now a user oriented accelerator. Several desirable features of the disc accelerator were proven. Initial magnetic insulation experiments on a 1.5 m-long-triplate show small energy and power losses. Theoretical understanding of magnetic insulation was greatly enhanced and agreement between projections and experiment were obtained

  6. Geometric group theory

    2018-01-01

    The key idea in geometric group theory is to study infinite groups by endowing them with a metric and treating them as geometric spaces. This applies to many groups naturally appearing in topology, geometry, and algebra, such as fundamental groups of manifolds, groups of matrices with integer coefficients, etc. The primary focus of this book is to cover the foundations of geometric group theory, including coarse topology, ultralimits and asymptotic cones, hyperbolic groups, isoperimetric inequalities, growth of groups, amenability, Kazhdan's Property (T) and the Haagerup property, as well as their characterizations in terms of group actions on median spaces and spaces with walls. The book contains proofs of several fundamental results of geometric group theory, such as Gromov's theorem on groups of polynomial growth, Tits's alternative, Stallings's theorem on ends of groups, Dunwoody's accessibility theorem, the Mostow Rigidity Theorem, and quasiisometric rigidity theorems of Tukia and Schwartz.

    The public opinion on Nuclear Power is not favorable. A purposeful work with public perception is necessary. One way to create a positive image of the nuclear industry is to improve public radiological education. This challenge can be resolved in the close cooperation with state school and preschool education. The formation about nuclear power should be simple and symbolical. Our society can be divided into 4 parts which can be called as target groups: First group - People from the nuclear industry with special education working at nuclear facilities or related to the industry. Second group - People working in the fields connected with nuclear power. Third group - People not related to nuclear power or even with negative impression to the industry. This group is the largest and the work required is the most difficult. Fourth group - The number of this group's members is the least, but it has strong influence on public opinion. 'Greens' and a broad spectrum of ecological organizations can be included in this group. (Authors)

    2006-01-01

    PowerPal micro-hydro equipment was developed in Vietnam by Asian Phoenix Resources Ltd. of Victoria, BC; a company who aims to help disadvantaged people in less developed countries by making renewable energy devices available to them. The idea for the micro-hydro system was conceived after mineral exploration parties in Vietnam noted that large numbers of poor quality propeller turbines were being used to supply AC power to individual homes. A plan was developed to improve the quality and reliability of low head turbines with better castings, magnets, superior bearings and electronic load controllers. Funding for the program was initially difficult to obtain. However, PowerPal micro-hydro equipment eventually came to the attention of the World Bank as well as other government and non-governmental organizations. Financing for the purchase and installation of larger numbers of units has now been achieved, and missionary groups in various parts of the world have ordered units. European markets have also opened up, and distributors of the micro-hydro equipment have been appointed in various countries. Sales are now strong in Central America, South America, the Caribbean, Australasia, Oceania, Africa and Europe. It was concluded that the surge of interest has coincided with a steep upturn in oil prices. 8 figs

    Based in Brussels, the European atomic forum FORATOM is the trade association of the European nuclear industry which was established in the early 1960s to promote nuclear power and to facilitate relations with the European institutions. One of the main mechanisms which FORATOM uses, in its dealings with the European Commission and other international organisations, is the involvement of several working groups bringing together groups of experts drawn from the industrial companies in order to identify the issues and to develop the widest possible common views on which the industry must express its representative, substantial and deliverable opinion. The Transport Working Group (TWG) has the objective of dealing with transport of radioactive material, especially nuclear materials. The TWG usually meets three times a year in Brussels or another selected location. It has strong links with the European Commission which are evidenced by the fact that it officially represents the European nuclear industry, with the status of observer, at the meetings of the Standing Working Group on Safe Transport of Radioactive Material which was set up in 1982, upon a request of the European Parliament, to advise the European Commission in the field of safe transport of radioactive materials. The Standing Working Group (SWG) assists the European Union's Member States in the revision process of IAEA recommendations and helps a correct and harmonious application of these recommendations within the European Union. In previous years, the Standing Working Group has proposed over 40 different studies, financed by the European Commission, on important transport issues. The FORATOM TWG encourages its member organisations to participate in studies proposed by the Commission and has been cooperating for many years with the Commission in the field of many studies aimed to improve the application of transport regulations.

    Wetrich, J G

    1987-07-01

    The various types and operational methods of purchasing groups are described, and evaluation of groups is discussed. Since group purchasing is increasing in popularity as a method of controlling drug costs, community and hospital pharmacy managers may need to evaluate various groups to determine the appropriateness of their services. Groups are categorized as independent, system based, or alliance or association based. Instead of "purchasing," some groups develop contracts for hospitals, which then purchase directly from the vendor. Aside from this basic difference between groups that purchase and groups that contract, comparisons among groups are difficult because of the wide variation in sizes and services. Competition developing from diversification among groups has led to "super groups," formed from local and regional groups. In evaluating groups, advantages and disadvantages germane to accomplishing the member's objectives must be considered. To ensure a group's success, members must be committed and support the group's philosophies; hospital pharmacists must help to establish a strong formulary system. To select vendors, groups should develop formal qualification and selection criteria and should not base a decision solely on price. The method of solicitation (bidding or negotiating), as well as the role of the prime vendor, should be studied. Legal implications of group purchasing, especially in the areas of administrative fees and drug diversion, must also be considered. The most advantageous group for each organization will include members with common missions and will be able to implement strategies for future success.

    Full Text Available Autistic traits can help people gain and sustain power, and has probably done so throughout history, says the present paper. A number of testable claims follow from this assumption. First, the powerful should have more autistic traits than others – which they do appear to have. Among other things, powerful people, and those with many autistic traits, tend to prefer solitary activities and are often aloof. Moreover, they are often rigid and socially insensitive, low on empathy and with low scores on the trait of agreeableness -- and as a rule they do not have many friends. Both groups are also more self-centered than others, more honest, less submissive, more sensitive to slights, and with a stronger tendency to engage in abstract thinking. They tend to behave in bossy or dominant ways, and their moral judgment is more based on rules than on feelings. In addition to experimental evidence, I cite biographies showing that a surprising number of presidents, prime ministers and other powerful people seem to have had traits like those in question – and interestingly, in animals, leaders are often rigid and insensitive to group members’ needs and feelings, mostly acting the way they are themselves inclined to, not responding much to others. Problem solving is important in leadership, and people with many autistic traits appear often to be better thinkers than typical subjects with similar IQs. However, these and other congruities could be coincidences. Hence the question of whether traits the two groups have in common also have a common cause constitutes a strong test of the paper’s thesis – and a common cause does appear to exist, in the form of testosterone’s effects on the central nervous system.

    1996-01-01

    The subjects of ordered groups and of infinite permutation groups have long en­ joyed a symbiotic relationship. Although the two subjects come from very different sources, they have in certain ways come together, and each has derived considerable benefit from the other. My own personal contact with this interaction began in 1961. I had done Ph. D. work on sequence convergence in totally ordered groups under the direction of Paul Conrad. In the process, I had encountered "pseudo-convergent" sequences in an ordered group G, which are like Cauchy sequences, except that the differences be­ tween terms of large index approach not 0 but a convex subgroup G of G. If G is normal, then such sequences are conveniently described as Cauchy sequences in the quotient ordered group GIG. If G is not normal, of course GIG has no group structure, though it is still a totally ordered set. The best that can be said is that the elements of G permute GIG in an order-preserving fashion. In independent investigations around that t...

    Several concrete measures have been initiated in Italy for the generation of nuclear power on a substantial scale. Two plants are already under construction and work will start soon on a third. Plans have also been announced for more stations. If the work already initiated is completed on schedule the installed capacity of nuclear power in Italy is likely to exceed 500 mw (electric) in the course of the next four years. This will constitute a sizeable proportion of the total electrical capacity in the country. After the Italian National Committee for Nuclear Research (Comitato Nazionale per le Ricerche Nucleari) was reorganized late in 1956, it prepared what can be described as a nuclear five-year plan for Italy. The plan, designed to cover the period 1957-1962, includes detailed schemes for a comprehensive development of the peaceful uses of nuclear energy, including a programme for the generation of power. The Comitato Nazionale per le Ricerche Nucleari (CNRN) promotes and co-ordinates the various activities in the field, and within the framework of its general programme certain industrial groups in Italy have formulated specific projects for nuclear power. At a Geneva conference (1958) it was disclosed that several companies were planning to build nuclear power stations in Italy. (1) SELNI (Societa Elettronucleare Italiana), pertaining to the Edison-Volta group, which plans to build a pressurized water reactor. (2) So.R.I.N. (Societa Ricerche Impianti Nucleari), a company founded by the Fiat and Montecatini groups, which is constructing a research centre, with a swimming pool reactor, and various laboratories for chemistry, physics and metallurgy. This centre will also be used for the training of specialized personnel, in view of the company's programme which envisages two 150 mw (e) plants: one operating with enriched uranium, the other with natural uranium. Such a programme will become effective only when the cost of power produced by these plants may actually

    This report summarizes the fiscal 1974 research result on 2- 6 group compound semiconductor solar cells. To obtain a probability of the technology for producing photovoltaic power generation systems at a cost less than 1/100 of those by current technology, this research aims at establishment of the pollution-free production technology of the titled solar cells, and development of an innovative photovoltaic power generation system using such solar cells. The research is composed of (1) study on deterioration mechanism, (2) measures against pollution, and (3) basic study on the production system of such semiconductors. In the 1st research, the analysis result showed that deterioration under solar radiation or by short circuit is derived from an increase in resistance around a positive electrode and a decrease around a junction caused by change in Cu{sub 2}S composition due to migration of Cu ions in a Cu{sub 2}S layer by photo current. In the 2nd research, study was made on preventive technology of Cd pollution. In the 3rd research, basic study was made on the production systems of semiconductors such as sintering, chemical separating and vapor-phase growth for cost reduction. (NEDO)

    Using a sample of galaxy groups found in the Sloan Digital Sky Survey Data Release 4, we measure the following four types of alignment signals: (1) the alignment between the distributions of the satellites of each group relative to the direction of the nearest neighbor group (NNG); (2) the alignment between the major axis direction of the central galaxy of the host group (HG) and the direction of the NNG; (3) the alignment between the major axes of the central galaxies of the HG and the NNG; and (4) the alignment between the major axes of the satellites of the HG and the direction of the NNG. We find strong signal of alignment between the satellite distribution and the orientation of central galaxy relative to the direction of the NNG, even when the NNG is located beyond 3r vir of the host group. The major axis of the central galaxy of the HG is aligned with the direction of the NNG. The alignment signals are more prominent for groups that are more massive and with early-type central galaxies. We also find that there is a preference for the two major axes of the central galaxies of the HG and NNG to be parallel for the system with both early central galaxies, however, not for the systems with both late-type central galaxies. For the orientation of satellite galaxies, we do not find any significant alignment signals relative to the direction of the NNG. From these four types of alignment measurements, we conclude that the large-scale environment traced by the nearby group affects primarily the shape of the host dark matter halo, and hence also affects the distribution of satellite galaxies and the orientation of central galaxies. In addition, the NNG directly affects the distribution of the satellite galaxies by inducing asymmetric alignment signals, and the NNG at very small separation may also contribute a second-order impact on the orientation of the central galaxy in the HG.

    The US Enron group and the Italian Enel group have decided to create a joint-venture for the production of electric power in Italy. Their activities will be based on the transformation of existing classical thermal power plants into natural gas fueled combined cycle power plants. The total capacity of the converted power plants will be of 5000 MW. Enron should invest about 3 billions of US Dollars in this project and will be in a privileged position when the Italian electric power market will be open to competition in 1999. Short paper.

  4. Thai Nuclear Power Program

    2011-01-01

    The Electricity Generating Authority of Thailand (EGAT), the main power producer in Thailand, was first interested in nuclear power as an electricity option in 1967 when the electricity demand increased considerably for the first time as a result of the economic and industrial growth. Its viability had been assessed several times during the early seventies in relation to the changing factors. Finally in the late 1970s, the proceeding with nuclear option was suspended for a variety of reasons, for instance, public opposition, economic repercussion and the uncovering of the indigenous petroleum resources. Nonetheless, EGAT continued to maintain a core of nuclear expertise. During 1980s, faced with dwindling indigenous fossil fuel resources and restrictions on the use of further hydro as an energy source, EGAT had essentially reconsidered introducing nuclear power plants to provide a significant fraction to the long term future electricity demand. The studies on feasibility, siting and environmental impacts were conducted. However, the project was never implemented due to economics crisis in 1999 and strong opposition by environmentalists and activists groups. The 1986 Chernobyl disaster was an important cause. After a long dormant period, the nuclear power is now reviewed as one part of the solution for future energy supply in the country. Thailand currently relies on natural gas for 70 percent of its electricity, with the rest coming from oil, coal and hydro-power. One-third of the natural gas consumed in Thailand is imported, mainly from neighbouring Myanmar. According to Power Development Plan (PDP) 2007 rev.2, the total installed electricity capacity will increase from 28,530.3 MW in 2007 to 44,281 MW by the end of plan in 2021. Significantly increasing energy demand, concerns over climate change and dependence on overseas supplies of fossil fuels, all turn out in a favor of nuclear power. Under the current PDP (as revised in 2009), two 1,000- megawatt nuclear

    Argentina has gone through very difficult times during the last years and, in particularly, new kinds of social practices have emerged in order to cope with the crisis. This situation demands and urges a new type of reflection upon the double role of groups, as tools to transform reality and as a way to elaborate those processes regarding subjectivity. In this paper we analyse some topics regarding the groupal field (considering spontaneous groups as well as groupal devices that allow to elaborate the crisis). We consider social bond to be the condition of possibility for the existence of the psyche and of time continuity, and that it also makes possible personal and social elaboration of trauma, crisis and social catastrophe. We develop some aspects of an specific device (the reflection group), which we have already depicted in another moment, showing it's usefulness to cope with social crisis and to promote the subjective elaboration of crisis.

  6. Power grids

    Viterbo, J.

    2012-01-01

    The implementation of renewable energies represents new challenges for electrical systems. The objective: making power grids smarter so they can handle intermittent production. The advent of smart grids will allow flexible operations like distributing energy in a multidirectional manner instead of just one way and it will make electrical systems capable of integrating actions by different users, consumers and producers in order to maintain efficient, sustainable, economical and secure power supplies. Practically speaking, they associate sensors, instrumentation and controls with information processing and communication systems in order to create massively automated networks. Smart grids require huge investments: for example more than 7 billion dollars have been invested in China and in the Usa in 2010 and France is ranked 9. worldwide with 265 million dollars invested. It is expected that smart grids will promote the development of new business models and a change in the value chain for energy. Decentralized production combined with the probable introduction of more or less flexible rates for sales or purchases and of new supplier-customer relationships will open the way to the creation of new businesses.

    This project is aimed at establishment of techniques for pollution-free production of II-VI group compound semiconductor type solar cells. The research items are (1) measures against aging, (2) methods for production of II-VI group compound semiconductors and for forming their joints, and (3) method for assembling solar cell devices.For the item (1), the aging tests are conducted for sintered film type CdS/CdTe solar cells. The C electrode is found to be less aged than the others. The aging tests for the CdS/Cu{sub 2}S cells indicate that it takes 10 years or longer for the performance to be halved under commercial conditions. For the item (2), the sintered film type CdS/CdTe solar cells can be produced by a mass-producible process of screen printing and belt furnace. This production method is promising for producing the solar cells at low cost. For the item (3), it is found that series resistance of the solar cell devices increases as the assembly area increases, resulting in decreased conversion efficiency. The divided structure of the CdTe layer is desired to avoid the above problem. Dividing each unit device increases intrinsic conversion efficiency, but decreases effective power generation area ratio. It is therefore necessary to improve printing precision. (NEDO)

    The paper describes research and development in the field of magnetohydrodynamic power generation technology, based on discussions held in the Joint IAEA/UNESCO International Liaison Group on MHD electrical power generation. Research and development programmes on open cycle, closed cycle plasma and liquid-metal MHD are described. Open cycle MHD has now entered the engineering development stage. The paper reviews the results of cycle analyses and economic and environmental evaluations: substantial agreement has been reached on the expected overall performance and necessary component specifications. The achievement in the Soviet Union on the U-25 MHD pilot plant in obtaining full rated electrical power of 20.4 MW is described, as well as long duration testing of the integrated operation of MHD components. Work in the United States on coal-fired MHD generators has shown that, with slagging of the walls, a run time of about one hundred hours at the current density and electric field of a commercial MHD generator has been achieved. Progress obtained in closed cycle plasma and liquid metal MHD is reviewed. Electrical power densities of up to 140 MWe/m 3 and an enthalpy extraction as high as 24 per cent have been achieved in noble gas MHD generator experiments. (Auth.)

    Cooperation is ubiquitous in the natural world. What seems nonsensical is why natural selection favors a behavior whereby individuals would lose out by benefiting their competitor. This conundrum, for almost half a century, has puzzled scientists and remains a fundamental problem in biology, psychology, and economics. In recent years, the explanation that punishment can maintain cooperation has received much attention. Individuals who punish noncooperators thrive when punishment does not entail a cost to the punisher. However when punishment is costly, cooperation cannot be preserved. Most literature on punishment fails to consider that punishers may act corruptly by not cooperating when punishing noncooperators. No research has considered that there might be power asymmetries between punishers and nonpunishers that turn one of these type of individuals more or less susceptible to experiencing punishment. Here, we formulate a general game allowing corruption and power asymmetries between punishers and nonpunishers. We show that cooperation can persist if punishers possess power and use it to act corruptly. This result provides a new interpretation of recent data on corrupt policing in social insects and the psychology of power and hypocrisy in humans. These results suggest that corruption may play an important role in maintaining cooperation in insects and human societies. In contrast with previous research, we contend that costly punishment can be beneficial for social groups. This work allows us to identify ways in which corruption can be used to the advantage of a society. © 2010 The Author(s). Evolution© 2010 The Society for the Study of Evolution.

    In the early fifties, the VGB working group 'Power station master training' elaborated plans for systematic and uniform training of power station operating personnel. In 1957, the first power station master course was held. In the meantime, 1.720 power station masters are in possession of a master's certificate of a chamber of commerce and trade. Furthermore, 53 power station masters have recently obtained in courses of the 'Kraftwerksschule e.V.' the know-how which enables them to also carry out their duty as a master in nuclear power stations.

    The Fermilab Steering Group has developed a plan to keep U.S. accelerator-based particle physics on the pathway to discovery, both at the Terascale with the LHC and the ILC and in the domain of neutrinos and precision physics with a high-intensity accelerator. The plan puts discovering Terascale physics with the LHC and the ILC as Fermilab's highest priority. While supporting ILC development, the plan creates opportunities for exciting science at the intensity frontier. If the ILC remains near the Global Design Effort's technically driven timeline, Fermilab would continue neutrino science with the NOVA experiment, using the NuMI (Neutrinos at the Main Injector) proton plan, scheduled to begin operating in 2011. If ILC construction must wait somewhat longer, Fermilab's plan proposes SNuMI, an upgrade of NuMI to create a more powerful neutrino beam. If the ILC start is postponed significantly, a central feature of the proposed Fermilab plan calls for building an intense proton facility, Project X, consisting of a linear accelerator with the currently planned characteristics of the ILC combined with Fermilab's existing Recycler Ring and the Main Injector accelerator. The major component of Project X is the linac. Cryomodules, radio-frequency distribution, cryogenics and instrumentation for the linac are the same as or similar to those used in the ILC at a scale of about one percent of a full ILC linac. Project X's intense proton beams would open a path to discovery in neutrino science and in precision physics with charged leptons and quarks. World-leading experiments would allow physicists to address key questions of the Quantum Universe: How did the universe come to be? Are there undiscovered principles of nature: new symmetries, new physical laws? Do all the particles and forces become one? What happened to the antimatter? Building Project X's ILC-like linac would offer substantial support for ILC development by accelerating the

    The aim of this study was to compare different typing methods, individually and combined, for use in the monitoring of Campylobacter in food. Campylobacter jejuni (n=94) and Campylobacter coli (n=52) isolated from different broiler meat carcasses were characterized using multilocus sequence typing (MLST), flagellin gene A restriction fragment length polymorphism typing (flaA-RFLP), antimicrobial resistance profiling (AMRp), the presence/absence of 5 putative virulence genes; and, exclusively for C. jejuni, the determination of lipooligosaccharide (LOS) class. Discriminatory power was calculated by the Simpson's index of diversity (SID) and the congruence was measured by the adjusted Rand index and adjusted Wallace coefficient. MLST was individually the most discriminative typing method for both C. jejuni (SID=0.981) and C. coli (SID=0.957). The most discriminative combination with a SID of 0.992 for both C. jejuni and C. coli was obtained by combining MLST with flaA-RFLP. The combination of MLST with flaA-RFLP is an easy and feasible typing method for short-term monitoring of Campylobacter in broiler meat carcass. Copyright © 2016 Elsevier B.V. All rights reserved.

    A sizeable sector of the public remains hesitant or opposed to the use of nuclear power. With other groups claiming nuclear power has a legitimate role in energy programs, there is a need to openly and objectively discuss the concerns limiting its acceptance: the perceived health effects, the consequences of severe accidents, and the disposal of high level waste. This paper discusses these concerns using comparisons with other energy sources. (author)

  17. Wind power

    Energy Technology Data Exchange (ETDEWEB)

    1979-01-01

    This publication describes some of the technical, economic, safety and institutional considerations involved in the selection, installation and evaluation of a wind generation system. This information is presented, where possible, in practical, non-technical terms. The first four sections provide background information, theory, and general knowledge, while the remaining six sections are of a more specific nature to assist the prospective owner of a wind generator in his calculations and selections. Meteorological information is provided relating to the wind regime in Nova Scotia. The section on cost analysis discusses some of the factors and considerations which must be examined in order to provide a logical comparison between the alternatives of electricity produced from other sources. The final two sections are brief summaries of the regulations and hazards pertaining to the use of wind generators. The cost of wind-generated electricity is high compared to present Nova Scotia Power Corporation rates, even on Sable Island, Nova Scotia's highest wind area. However, it may be observed that Sable Island is one of the areas of Nova Scotia which is not presently supplied through the power grid and, particularly if there was a significant increase in the price of diesel oil, wind-generated electricity may well be the most economical alternative in that area. Generally speaking, however, where a consumer can purchase electricity at the normal domestic rate, wind generators are not economical, and they will not become economical unless there is a great reduction in their cost, an great increase in electricity rates, or both. Includes glossary. 23 figs., 11 tabs.
