We present direct detection constraints on the absorption of hidden-photon dark matter with particle masses in the range 1.2-30 eV$c^{-2}$ with the DAMIC experiment at SNOLAB. Under the assumption that the local dark matter is entirely constituted of hidden photons, the sensitivity to the kinetic mixing parameter $\\kappa$ is competitive with constraints from solar emission, reaching a minimum value of 2.2$\\times$$10^{-14}$ at 17 eV$c^{-2}$. These results are the most stringent direct detection constraints on hidden-photon dark matter with masses 3-12 eV$c^{-2}$ and the first demonstration of direct experimental sensitivity to ionization signals $<$12 eV from dark matter interactions.

Poly(3-hydroxybutyrate) (PHB) production and mobilization in Ralstonia eutropha are well studied, but in only a few instances has PHB production been explored in relation to other cellular processes. We examined the global gene expression of wild-type R. eutropha throughout the PHB cycle: growth on fructose, PHB production using fructose following ammonium depletion, and PHB utilization in the absence of exogenous carbon after ammonium was resupplied. Our results confirm or lend support to previously reported results regarding the expression of PHB-related genes and enzymes. Additionally, genes for many different cellular processes, such as DNA replication, cell division, and translation, are selectively repressed during PHB production. In contrast, the expression levels of genes under the control of the alternative sigma factor sigma(54) increase sharply during PHB production and are repressed again during PHB utilization. Global gene regulation during PHB production is strongly reminiscent of the gene expression pattern observed during the stringent response in other species. Furthermore, a ppGpp synthase deletion mutant did not show an accumulation of PHB, and the chemical induction of the stringent response with DL-norvaline caused an increased accumulation of PHB in the presence of ammonium. These results indicate that the stringent response is required for PHB accumulation in R. eutropha, helping to elucidate a thus-far-unknown physiological basis for this process.

Paolo Giorgi Rossi

Full Text Available Pap test, and especially HPV DNA test, identify a large group of women who do not have any clinically relevant lesions, i.e., CIN2+ (Cervical Intraepithelial Neoplasia grade 2 or worse, but who are at greater risk of getting lesions in the future. The follow up of these women needs new biomarkers with prognostic value. The objective of this study is to evaluate the prognostic value of E6/E7 mRNA over-expression assay (PreTect HPV-Proofer, Norchip for 5 HR-HPV types (16, 18, 31, 33, and 45 for progression to CIN2+ after a negative colposcopy. This prospective study, conducted at four Italian centres, enrolled 673 women with either a negative colposcopy or a negative or CIN1 histology. The clinical end-point was histological confirmation of CIN2+. Women were classified at baseline according to mRNA results and managed according to local colposcopy protocols. At least one conclusive follow-up test was obtained for 347 women (25 months average lapse since recruitment, range 5-74. Only seven CIN2+ were detected during follow up, three among the 82 women positive for mRNA at baseline, two among the 250 negative (Fisher exact test, p = 0.02, and two among the 12 with an invalid test. Absolute CIN2+ risk was 6.7/1,000 person/years in the whole cohort. The absolute CIN2+ risk was 18.4/1,000 person/years and 3.6/1,000 person/years in mRNA-positive and mRNA-negative women, respectively. In conclusion, E6/E7 mRNA over-expression appears to be a good candidate as a prognostic biomarker to manage HR-HPV DNA-positive women with negative colposcopy or histology, particularly in order to decrease follow-up intensity in those who are negative.

Flight Hardware Packaging Design for Stringent EMC Radiated Emission Requirements

Science.gov (United States)

Lortz, Charlene L.; Huang, Chi-Chien N.; Ravich, Joshua A.; Steiner, Carl N.

2013-01-01

This packaging design approach can help heritage hardware meet a flight project's stringent EMC radiated emissions requirement. The approach requires only minor modifications to a hardware's chassis and mainly concentrates on its connector interfaces. The solution is to raise the surface area where the connector is mounted by a few millimeters using a pedestal, and then wrapping with conductive tape from the cable backshell down to the surface-mounted connector. This design approach has been applied to JPL flight project subsystems. The EMC radiated emissions requirements for flight projects can vary from benign to mission critical. If the project's EMC requirements are stringent, the best approach to meet EMC requirements would be to design an EMC control program for the project early on and implement EMC design techniques starting with the circuit board layout. This is the ideal scenario for hardware that is built from scratch. Implementation of EMC radiated emissions mitigation techniques can mature as the design progresses, with minimal impact to the design cycle. The real challenge exists for hardware that is planned to be flown following a built-to-print approach, in which heritage hardware from a past project with a different set of requirements is expected to perform satisfactorily for a new project. With acceptance of heritage, the design would already be established (circuit board layout and components have already been pre-determined), and hence any radiated emissions mitigation techniques would only be applicable at the packaging level. The key is to take a heritage design with its known radiated emissions spectrum and repackage, or modify its chassis design so that it would have a better chance of meeting the new project s radiated emissions requirements.

Sensitivity Analysis in Observational Research: Introducing the E-Value.

Science.gov (United States)

VanderWeele, Tyler J; Ding, Peng

2017-08-15

Sensitivity analysis is useful in assessing how robust an association is to potential unmeasured or uncontrolled confounding. This article introduces a new measure called the "E-value," which is related to the evidence for causality in observational studies that are potentially subject to confounding. The E-value is defined as the minimum strength of association, on the risk ratio scale, that an unmeasured confounder would need to have with both the treatment and the outcome to fully explain away a specific treatment-outcome association, conditional on the measured covariates. A large E-value implies that considerable unmeasured confounding would be needed to explain away an effect estimate. A small E-value implies little unmeasured confounding would be needed to explain away an effect estimate. The authors propose that in all observational studies intended to produce evidence for causality, the E-value be reported or some other sensitivity analysis be used. They suggest calculating the E-value for both the observed association estimate (after adjustments for measured confounders) and the limit of the confidence interval closest to the null. If this were to become standard practice, the ability of the scientific community to assess evidence from observational studies would improve considerably, and ultimately, science would be strengthened.

Zhang, J.-Y.; Mitroy, J.

2007-01-01

Close to converged energies and expectation values for e + PsH are computed using a ground-state wave function consisting of 1500 explicitly correlated Gaussians. The best estimate of the e + PsH ∞ energy was -0.810 254 hartrees, which has a binding energy of 0.021 057 hartrees against dissociation into e + +PsH. The 2γ annihilation rate was 2.7508x10 9 s -1 . Binding energies and annihilation rates are also given for the different finite-mass variants of e + PsH. Comparisons between expectation values for e + PsH and PsH provide compelling evidence that the e + PsH ground state can be regarded as consisting of a weakly bound positron orbiting the PsH ground state

2012-06-01

Full Text Available Abstract Background The aim of this study was to investigate the role of specific IgG4 antibodies to hen’s egg white and determine their utility as a marker for the outcome of oral challenge test in children sensitized to hen’s egg Methods The hen’s egg oral food challenge test was performed in 105 sensitized children without atopic dermatitis, and the titers of egg white-specific immunoglobulin G4 (IgG4 and immunoglobulin E (IgE antibodies were measured. To set the cut-off values of IgG4, IgE, and the IgE/IgG4 ratio for predicting positive results in oral challenges, receiver operating characteristic curves were plotted and the area under the curves (AUC were calculated. Results Sixty-four of 105 oral challenges with whole eggs were assessed as positive. The AUC for IgE, IgG4, and IgE/IgG4 for the prediction of positive results were 0.609, 0.724, and 0.847, respectively. Thus, the IgE/IgG4 ratio generated significantly higher specificity, sensitivity, positive predictive value (%, and negative predictive value (% than the individual IgE and IgG4. The negative predictive value of the IgE/IgG4 ratio was 90% at a value of 1. Conclusions We have demonstrated that the egg white-specific serum IgE/IgG4 ratio is important for predicting reactivity to egg during food challenges.

Systematics of B(E2;01+→21+) values for even-even nuclei

Raman, S.; Nestor, C.W. Jr.; Bhatt, K.H.

1988-01-01

We have completed a compilation of experimental results for the electric quadrupole transition probability B(E2)up-arrow between the 0 + ground state and the first 2 + state in even-even nuclei. The adopted B(E2)up-arrow values have been employed to test the various systematic, empirical, and theoretical relationships proposed by several authors (Grodzins, Bohr and Mottelson, Wang et al., Ross and Bhaduri, Patnaik et al., Hamamoto, Casten, Moeller and Nix, and Kumar) on a global, local, or regional basis. These systematics offer methods for making reasonable predictions of unmeasured B(E2) values. For nuclei away from closed shells, the SU(3) limit of the intermediate boson approximation implies that the B(E2)up-arrow values are proportional to (e/sub p/N/sub p/+e/sub n/N/sub n/) 2 , where e/sub p /(e/sub n/) is the proton (neutron) effective charge and N/sub p/ (N/sub n/) refers to the number of valence protons (neutrons). This proportionality is consistent with the observed behavior of B(E2)up-arrow vs N/sub p/N/sub n/. For deformed nuclei and the actinides, the B(E2)up-arrow values calculated in a schematic single-particle ''SU(3)'' simulation or large single-j simulation of major shells successfully reproduce not only the empirical variation of the B(E2)up-arrow values but also the observed saturation of these values when plotted against N/sub p/N/sub n/. .AE

Augmenting the Genetic Toolbox for Sulfolobus islandicus with a Stringent Positive Selectable Marker for Agmatine Prototrophy

Science.gov (United States)

Cooper, Tara E.; Krause, David J.

2013-01-01

Sulfolobus species have become the model organisms for studying the unique biology of the crenarchaeal division of the archaeal domain. In particular, Sulfolobus islandicus provides a powerful opportunity to explore natural variation via experimental functional genomics. To support these efforts, we further expanded genetic tools for S. islandicus by developing a stringent positive selection for agmatine prototrophs in strains in which the argD gene, encoding arginine decarboxylase, has been deleted. Strains with deletions in argD were shown to be auxotrophic for agmatine even in nutrient-rich medium, but growth could be restored by either supplementation of exogenous agmatine or reintroduction of a functional copy of the argD gene from S. solfataricus P2 into the ΔargD host. Using this stringent selection, a robust targeted gene knockout system was established via an improved next generation of the MID (marker insertion and unmarked target gene deletion) method. Application of this novel system was validated by targeted knockout of the upsEF genes involved in UV-inducible cell aggregation formation. PMID:23835176

E-CAI: a novel server to estimate an expected value of Codon Adaptation Index (eCAI

Directory of Open Access Journals (Sweden)

Garcia-Vallvé Santiago

2008-01-01

Full Text Available Abstract Background The Codon Adaptation Index (CAI is a measure of the synonymous codon usage bias for a DNA or RNA sequence. It quantifies the similarity between the synonymous codon usage of a gene and the synonymous codon frequency of a reference set. Extreme values in the nucleotide or in the amino acid composition have a large impact on differential preference for synonymous codons. It is thence essential to define the limits for the expected value of CAI on the basis of sequence composition in order to properly interpret the CAI and provide statistical support to CAI analyses. Though several freely available programs calculate the CAI for a given DNA sequence, none of them corrects for compositional biases or provides confidence intervals for CAI values. Results The E-CAI server, available at http://genomes.urv.es/CAIcal/E-CAI, is a web-application that calculates an expected value of CAI for a set of query sequences by generating random sequences with G+C and amino acid content similar to those of the input. An executable file, a tutorial, a Frequently Asked Questions (FAQ section and several examples are also available. To exemplify the use of the E-CAI server, we have analysed the codon adaptation of human mitochondrial genes that codify a subunit of the mitochondrial respiratory chain (excluding those genes that lack a prokaryotic orthologue and are encoded in the nuclear genome. It is assumed that these genes were transferred from the proto-mitochondrial to the nuclear genome and that its codon usage was then ameliorated. Conclusion The E-CAI server provides a direct threshold value for discerning whether the differences in CAI are statistically significant or whether they are merely artifacts that arise from internal biases in the G+C composition and/or amino acid composition of the query sequences.

Our limit on B (J /ψ →D0e+e-+c .c .) is more stringent by 2 orders of magnitude than the previous results, and B (ψ (3686 )→D0e+e-+c .c .) is measured for the first time.

Achieving stringent climate targets. An analysis of the role of transport and variable renewable energies using energy-economy-climate models

Energy Technology Data Exchange (ETDEWEB)

Pietzcker, Robert Carl

2014-07-01

technologies photovoltaics (PV) and concentrating solar power (CSP) in REMIND confirms the dominant role of these variable renewable energies for the decarbonization of the power sector. Recent cost reductions have brought PV to cost-competitiveness in regions with high midday electricity demand and high solar irradiance. The representation of system integration costs in REMIND is found to have significant impact on the competition between PV and CSP in the model: the low integration requirements of CSP equipped with thermal storage and hydrogen co-firing make CSP competitive at high shares of variable renewable energies, which leads to substantial deployment of both PV and CSP in low stabilization scenarios. A cross-model study of transport sector decarbonization confirms the earlier finding that the transport sector is not very reactive to intermediate carbon price levels: Until 2050, transport decarbonization lags 10-30 years behind the decarbonization of other sectors, and liquid fuels dominate the transport sector. In the long term, however, transportation does not seem to be an insurmountable barrier to stringent climate targets: As the price signals on CO{sub 2} increase further, transport emissions can be reduced substantially - if either hydrogen fuel cells or electromobility open a route to low-carbon energy carriers, or second generation biofuels (possibly in combination with CCS) allow the use of liquid-based transport modes with low emissions. The last study takes up the fundamental question of this thesis and analyses the trade-off between the stringency of a climate target and the resulting techno-economic requirements and costs. We find that transforming the global energy-economy system to keep a two-thirds likelihood of limiting global warming to below 2 C is achievable at moderate economic implications. This result is contingent on the near-term implementation of stringent global climate policies and full availability of several technologies that are still in

Induction of a stringent metabolic response in intracellular stages of Leishmania mexicana leads to increased dependence on mitochondrial metabolism.

Directory of Open Access Journals (Sweden)

Eleanor C Saunders

2014-01-01

Full Text Available Leishmania parasites alternate between extracellular promastigote stages in the insect vector and an obligate intracellular amastigote stage that proliferates within the phagolysosomal compartment of macrophages in the mammalian host. Most enzymes involved in Leishmania central carbon metabolism are constitutively expressed and stage-specific changes in energy metabolism remain poorly defined. Using (13C-stable isotope resolved metabolomics and (2H2O labelling, we show that amastigote differentiation is associated with reduction in growth rate and induction of a distinct stringent metabolic state. This state is characterized by a global decrease in the uptake and utilization of glucose and amino acids, a reduced secretion of organic acids and increased fatty acid β-oxidation. Isotopomer analysis showed that catabolism of hexose and fatty acids provide C4 dicarboxylic acids (succinate/malate and acetyl-CoA for the synthesis of glutamate via a compartmentalized mitochondrial tricarboxylic acid (TCA cycle. In vitro cultivated and intracellular amastigotes are acutely sensitive to inhibitors of mitochondrial aconitase and glutamine synthetase, indicating that these anabolic pathways are essential for intracellular growth and virulence. Lesion-derived amastigotes exhibit a similar metabolism to in vitro differentiated amastigotes, indicating that this stringent response is coupled to differentiation signals rather than exogenous nutrient levels. Induction of a stringent metabolic response may facilitate amastigote survival in a nutrient-poor intracellular niche and underlie the increased dependence of this stage on hexose and mitochondrial metabolism.

The Wisdom of e-crowds: Can Masses Create Value?

Directory of Open Access Journals (Sweden)

Wieczerzycki Marcin

2016-09-01

Full Text Available With the rising popularity of the Internet, interactions between companies and their consumers have become more common and meaningful. Researchers often tend to apply the metaphor of community to these on-line networks of B2C relationships. However, this term implies durability and a long-term orientation. It does not cover more incidental, short-lived groups of consumers, who therefore should not be treated as communities. The purpose of this paper is to explore the ability of these short-term, collective consumer phenomena (addressed as e-crowds within the scope of this paper to create value. Based on a critical literature analysis that considers works from several different fields of knowledge (including management, economics, psychology and media studies and empirical examples, we argue that while lacking a complex internal organization, e-crowds are capable of creating use, exchange and sign value when certain conditions are met. However, they are equally likely to perform value-destroying activities, which present real risks for companies that interact with e-crowds.

Dual Regulation of Bacillus subtilis kinB Gene Encoding a Sporulation Trigger by SinR through Transcription Repression and Positive Stringent Transcription Control.

Fujita, Yasutaro; Ogura, Mitsuo; Nii, Satomi; Hirooka, Kazutake

2017-01-01

It is known that transcription of kinB encoding a trigger for Bacillus subtilis sporulation is under repression by SinR, a master repressor of biofilm formation, and under positive stringent transcription control depending on the adenine species at the transcription initiation nucleotide (nt). Deletion and base substitution analyses of the kinB promoter (P kinB ) region using lacZ fusions indicated that either a 5-nt deletion (Δ5, nt -61/-57, +1 is the transcription initiation nt) or the substitution of G at nt -45 with A (G-45A) relieved kinB repression. Thus, we found a pair of SinR-binding consensus sequences (GTTCTYT; Y is T or C) in an inverted orientation (SinR-1) between nt -57/-42, which is most likely a SinR-binding site for kinB repression. This relief from SinR repression likely requires SinI, an antagonist of SinR. Surprisingly, we found that SinR is essential for positive stringent transcription control of P kinB . Electrophoretic mobility shift assay (EMSA) analysis indicated that SinR bound not only to SinR-1 but also to SinR-2 (nt -29/-8) consisting of another pair of SinR consensus sequences in a tandem repeat arrangement; the two sequences partially overlap the '-35' and '-10' regions of P kinB . Introduction of base substitutions (T-27C C-26T) in the upstream consensus sequence of SinR-2 affected positive stringent transcription control of P kinB , suggesting that SinR binding to SinR-2 likely causes this positive control. EMSA also implied that RNA polymerase and SinR are possibly bound together to SinR-2 to form a transcription initiation complex for kinB transcription. Thus, it was suggested in this work that derepression of kinB from SinR repression by SinI induced by Spo0A∼P and occurrence of SinR-dependent positive stringent transcription control of kinB might induce effective sporulation cooperatively, implying an intimate interplay by stringent response, sporulation, and biofilm formation.

Close to converged energies and expectation values for e + Li are computed using a ground state wave function consisting of 1200 explicitly correlated Gaussians. The best estimate of the e + Li energy was -7.532 895 5 hartree which has a binding energy of 0.002 482 hartree against dissociation into Ps+Li + . The 2γ annihilation rate for the spin singlet state was 6.996x10 9 s -1 . The annihilation rate for the triplet state, taking into account core annihilation and the 3γ decay, was 9.36x10 6 s -1

Signatures of massive sgoldstinos at e+e- colliders

International Nuclear Information System (INIS)

Perazzi, Elena; Ridolfi, Giovanni; Zwirner, Fabio

2000-01-01

In supersymmetric extensions of the Standard Model with a very light gravitino, the effective theory at the weak scale should contain not only the goldstino G-tilde, but also its supersymmetric partners, the sgoldstinos. In the simplest case, the goldstino is a gauge-singlet and its superpartners are two neutral spin-0 particles, S and P. We study possible signals of massive sgoldstinos at e + e - colliders, focusing on those that are most relevant at LEP energies. We show that the LEP constraints on e + e - →γS (γP), ZS (ZP) or e + e - S (e + e - P), followed by S(P) decaying into two gluon jets, can lead to stringent combined bounds on the gravitino and sgoldstino masses

Direct check of QED in e/sup +/e/sup -/ interactions at high q/sup 2/- values

A study of 1824 e/sup +/e/sup -/ to e/sup +or-/e/sup -or+/ events in the total centre-of-mass energy range from 1.6 GeV to 2.0 GeV, allows one to establish that production angular distributions, acollinearity and acoplanarity distributions, and absolute value of the cross- sections and their energy-dependence, follow QED predictions including first-order radiative corrections. In particular, the absolute value of the cross-section and the power of its energy-dependence agree with theoretical expectations within +or-6% and +or-2%, respectively. The inadequacy of the peaking approximation in the experimental conditions of observations has been measured to be (2.8+or-0.4)%. (6 refs).

Stringent limits on the ionized mass loss from A and F dwarfs

International Nuclear Information System (INIS)

Brown, A.; Veale, A.; Judge, P.; Bookbinder, J.A.; Hubeny, I.

1990-01-01

Following the suggestion of Willson et al. (1987) that A- and F-type main-sequence stars might undergo significant mass loss due to pulsationally driven winds, upper limits to the ionized mass loss from A and F dwarfs have been obtained using VLA observations. These stringent upper limits show that the level of ionized mass loss would have at most only a small effect on stellar evolution. Radiative-equilibrium atmospheric and wind models for early A dwarfs indicate that it is highly likely that a wind flowing from such stars would be significantly ionized. In addition, late A and early F dwarfs exhibit chromospheric emission indicative of significant nonradiative heating. The present mass-loss limits are thus representative of the total mass-loss rates for these stars. It is concluded that A and F dwarfs are not losing sufficient mass to cause A dwarfs to evolve into G dwarfs. 24 refs

Thermodynamic properties of (an ester+an alkane). XVII. Experimental HmE and VmE values for (an alkyl propanoate+an alkane) at 318.15K

International Nuclear Information System (INIS)

Ortega, J.; Espiau, F.; Toledo, F.J.; Dieppa, R.

2005-01-01

In this article, we record the experimental values of H m E and V m E , obtained at a temperature of T=318.15K and atmospheric pressure for a set of 30 binary mixtures comprised of five alkyl propanoates (methyl to pentyl) with six odd alkanes (heptane to heptadecane). The net values obtained for these properties are the result of different effects of the selected compounds on the mixing process. These effects and the variation with temperature are studied. The H m E are positive in all cases and increase with the saturated hydrocarbon chain and diminish with the alkanolic portion of the ester. The variation in V m E is similar to that occurring in the H m E . For the data correlation, a new form of polynomial equation is used in which the variable is the so-called active fraction which, in turn, is a function of the concentration of the mixture, giving acceptable estimations for simultaneous correlations between the values of Gibbs function obtained in the isobaric (liquid+vapour) equilibria and the enthalpies of the mixture, for some of the mixtures studied. The results are explained with the molecular model proposed for (ester+alkane) mixtures. Finally, the application of two versions of the UNIFAC groups contribution method to estimate enthalpies of the mixtures does not give satisfactory results, although the modified UNIFAC gives somewhat better results

E-learning: controlling costs and increasing value.

Science.gov (United States)

Walsh, Kieran

2015-04-01

E-learning now accounts for a substantial proportion of medical education provision. This progress has required significant investment and this investment has in turn come under increasing scrutiny so that the costs of e-learning may be controlled and its returns maximised. There are multiple methods by which the costs of e-learning can be controlled and its returns maximised. This short paper reviews some of those methods that are likely to be most effective and that are likely to save costs without compromising quality. Methods might include accessing free or low-cost resources from elsewhere; create short learning resources that will work on multiple devices; using open source platforms to host content; using in-house faculty to create content; sharing resources between institutions; and promoting resources to ensure high usage. Whatever methods are used to control costs or increase value, it is most important to evaluate the impact of these methods.

The evaluation is an important approach to promote the development of the E-Government. Since the rapid development of E-Government in the world, the E-Government performance evaluation has become a hot issue in the academia. In this paper, we develop a new evaluation method for the development of the E-Government based on the interval-valued intuitionistic fuzzy set which is a powerful technique in expressing the uncertainty of the real situation. First, we extend the geometric Heronian mean (GHM) operator to interval-valued intuitionistic fuzzy environment and proposed the interval-valued intuitionistic fuzzy GHM (IIFGHM) operator. Then, we investigate the relationships between the IIFGHM operator and some existing ones, such as generalized interval-valued intuitionistic fuzzy HM (GIIFHM) and interval-valued intuitionistic fuzzy weighted Bonferoni mean operator. Furthermore, we validate the effectiveness of the proposed method using a real case about the E-Government evaluation in Hangzhou City, China.

Interception of values as a result of the business model restructuring – case study

Nogalski Bogdan

2017-12-01

Full Text Available The main objective of this paper is to present a case of value interception as a result of restructuring the business model of a manufacturing company that operates in the agricultural machinery sector. A company that focuses on core activities in the value chain and commissions the manufacturing of most components to specialised suppliers – as a result of restructuring – becomes an integrator that controls all parts of the supply chain; from obtaining a raw material, through its own production of a possibly large number of components, to the distribution of a finished composite product. The framework of the conducted research featured the identification of the relationships occurring between own production of components comprising a given product, and an alternative solution, i.e. possibility of acquiring them by way of co-operation. The authors assumed that a derivative of the value intercepted in the finished product implementation process is the number of components manufactured using own production resources.

2010-01-01

The ALPS collaboration runs a ''Light Shining through a Wall'' (LSW) experiment to search for photon oscillations into ''Weakly Interacting Sub-eV Particles'' (WISPs) often predicted by extensions of the Standard Model. The experiment is set up around a superconducting HERA dipole magnet at the site of DESY. Due to several upgrades of the experiment we are able to place limits on the probability of photon-WISP-photon conversions of a few x 10 -25 . These limits result in today's most stringent laboratory constraints on the existence of low mass axion-like particles, hidden photons and minicharged particles. (orig.)

1998-07-01

We established the cutoff value for plasma folic acid, using plasma homocyst(e)ine as the functional marker. To do this, we investigated the relationship of the plasma folic acid of 103 apparently healthy adults with their fasting plasma homocyst(e)ine and with their plasma homocyst(e)ine 6 h after oral methionine challenge (100 mg/kg). We also studied the relationship of their plasma folic acid with the decline of fasting plasma homocyst(e)ine after 7 days of folic acid supplementation (5 mg/day). The three approaches suggested a cutoff value of 10 nmol/L. The chances of individuals to significantly (P ine after folic acid supplementation proved significantly higher at plasma folic acid concentrations < or = 10 nmol/L, as compared with folic acid concentrations above this value (odds ratio, 5.02; 95% confidence interval, 1.87-13.73). We suggest adopting a 10 nmo/L plasma folic acid cutoff value on functional grounds.

Value-added benefits of technology: e-procurement and e-commerce related to the health care industry.

Smith, Alan D; Correa, Joseph

2005-01-01

To provide insights into the current supply chain for original equipment manufacturers (OEM) in the radiology diagnostic imaging equipment business. As is common in many manufacturing and service firms, the rationale of bridging suppliers of OEMs is the ability to leverage technology, software, and accessories pertaining to the various pieces of equipment. Several models of e-procurement and e-commerce related to the health care industry are presented. Although the radiology capital equipment market presents numerous idiosyncrasies that must be addressed to successfully implement an e-business strategy effectively, incredible opportunities exist all along the supply chain for e-business strategies to both eliminate costs and acquire strategic initiatives. Those firms that most successfully listen to their customers and address the barriers to efficiency (B2E) will help move the industry toward more effective utilization of the benefits e-business can create and also obtain first mover advantages. Although the efficiencies that e-business provides are extremely important in the radiology capital equipment market, the main value of e-business in this industry of high-priced and relatively infrequently purchased equipment may well be the value-added benefits the technology brings to its customers, as illustrated in the modeling process. The OEMs that eventually market their finished product directly to hospital and imaging centers via a direct sales force can best take advantage of the connectivity and accessibility of e-commerce.

2014-01-01

We complete the two-loop calculation of β-functions for vacuum expectation values (VEVs) in gauge theories by the missing O(g 4 )-terms. The full two-loop results are presented for generic and supersymmetric theories up to two-loop level in arbitrary R ξ -gauge. The results are obtained by means of a scalar background field, identical to our previous analysis. As a by-product, the two-loop scalar anomalous dimension for generic supersymmetric theories is presented. As an application we compute the β-functions for VEVs and tan β in the MSSM, NMSSM, and E 6 SSM

1985-01-01

A survey is presented of Mark III results on the iota(1440), a possible glueball state observed in radiative J/psi decays. The measurements include a spin-parity determination using both the iota → Ksub(s) 0 K +- π +- and iota → K + K - π 0 decay modes; an upper limit on the K*anti-K content of the Kanti-Kπ Dalitz plot; branching fractions and isospin; stringent upper limits for several hadronic channels, including iota → zetaπ→etaππ; and results from a search for iota radiative decays into vector mesons. These measurements are discussed in the context of theoretical ideas about the iota and results on the E(1420), a state observed in hadronic interactions. 11 refs., 7 figs

Close to converged energies and expectation values for e + He( 3 S e ) are computed using a ground state wave function consisting of 1500 explicitly correlated Gaussians. The best estimate of the e + He( 3 S e ) energy was -2.250 595 08 hartree, which has a binding energy of 0.000 595 08 hartree against dissociation into Ps+He + . The 2γ annihilation rate for the spin doublet state was 5.713x10 9 s -1 . The estimated annihilation rate with the core He + electron was 2.506x10 6 s -1 . The derived enhancement factor for annihilation with the He + (1s) core was 2.29, just over 10% smaller than the enhancement factor derived from analyses of annihilation during e + -He + scattering. The diffuse nature of the wave function, with well separated He + and Ps subsystems, is demonstarted to be on the threshold of satisfying the formal criteria that define a quantum halo state

M1-E2 mixing ratios and B(E2) values for transitions in 131Xe

International Nuclear Information System (INIS)

Vijay Sai, K.; Deepa, S.; Ashish, T.; Venkataramaniah, K.; Madhusudan, K.

2012-01-01

The accuracies of M1-E2 mixing ratios calculated from the experimental conversion coefficients α i depend upon the accuracy with which the conversion coefficients are determined and also on the accuracy of the theoretical values. Recently a new calculation of ICCs by Band et al, BRICC has been published. The calculations are based on the relativistic DF method in which the exchange interactions between bound electrons and free electrons receding to infinity during the conversion process are treated exactly. Gerl et al showed that BRICC values are more closer to experimental values when compared to earlier theoretical values of Hager and Seltzer and Rosel. The availability of the BRICC values is expected to increase the accuracy with which the estimated quadrupole contents can be obtained

Are Dutch residents ready for a more stringent policy to enhance the energy performance of their homes?

International Nuclear Information System (INIS)

Middelkoop, Manon van; Vringer, Kees; Visser, Hans

2017-01-01

Investments in the energy performance of houses offer good prospects for reducing energy consumption and CO_2 emissions. However, people are not easily convinced of the need to take measures to improve the energy performance of their houses, even when financial benefits outweigh the costs. This article analyses the factors that influence the decision for improving the energy performance of existing homes, including policy instruments. Subsequently, the article provides policy suggestions on how to stimulate energy performance improvements. Both owners and tenants (50–70%) support government policy on energy performance improvements to existing homes. Nevertheless, people also have strong feelings of autonomy regarding their homes. Our results underline the importance of well-informed and competent decision-makers. Introducing the use of Energy Performance Certificates (EPCs) into the tax system for energy and residential buildings might therefore be an effective way to increase the interest of owners in the EPC, improve the use and effect of this informative instrument, and make the first step towards bridging the tension between autonomy and more stringent instruments.

Recently, a set of nine nonmagic nuclei with anomalous values of the B(E2) ratio B 4/2 ≡B(E2;4 1 + →2 1 + )/B(E2;2 1 + →0 1 + ) 1 + →2 1 + ) values for two of these nuclei, 98 Ru and 180 Pt, were re-measured to determine if the current literature values for these nuclei are correct. 98 Ru was studied in a 27 Al( 98 Ru, 98 Ru*) Coulomb excitation experiment in inverse kinematics, while the lifetime of the 4 1 + state in 180 Pt was measured in a 122 Sn( 62 Ni, 4n) 180 Pt recoil distance method (RDM) experiment. For both nuclei, the remeasured B 4/2 values are well above 1, removing the deviations from collective models

The evolution of B(E2) values around the doubly-magic nucleus {sup 132}Sn

Energy Technology Data Exchange (ETDEWEB)

Behrens, Thomas

2009-08-24

In this work the evolution of B(E2) values in nuclei around the N=82 shell closure has been studied. The reduced transition strength between ground state and rst excited 2{sup +} state is a good indicator for the collectivity in even-even nuclei. Former experimental and theoretical investigations of the region above N=82 indicated that the B(E2) values might be systematically lower than expected and questioned the current understanding of collective excitations. Since the experimental data concerning the proposed N=82 shell quenching for nuclei below {sup 132}Sn is not yet conclusive, a systematic investigation of neutron-rich nuclei both below and above this shell closure has been performed at the Radioactive Ion Beam Facility REX-ISOLDE at CERN. The B(E2) values of {sup 122-126}Cd (N<82) and {sup 138-144}Xe (N>82) have been measured by Coulomb excitation in inverse kinematics, applying the MINIBALL {gamma}-detector array. The values of {sup 124,126}Cd and {sup 138,142,144}Xe have been determined for the first time, whereas for {sup 140}Xe the ambiguity of the two contradicting published B(E2) values has been solved. The relative uncertainty of the B(E2) value of {sup 122}Cd could be reduced significantly. For {sup 140,142}Xe the Coulomb excitation cross section for the 2{sub 1}{sup +}{yields}4{sub 1}{sup +} transition has also been determined. Further, the deorientation e ect and the influence of the quadrupole deformation on the Coulomb excitation cross section have been taken into account for {sup 138-142}Xe. It could be shown that the latter plays an important role for the determination of the B(E2) values. Assuming only a small or even vanishing quadrupole moment, all measured B(E2) values agree with the expectations and no sign for a quenching of the N=82 gap could be seen. (orig.)

Key to the realization of gene therapy is the development of efficient and targeted gene transfer vectors. Therapeutic gene transfer by replication-deficient or more recently by conditionally replication-competent/oncolytic adenoviruses has shown much promise. For specific applications, however, it will be advantageous to provide vectors that allow for external control of gene expression. The efficient cellular heat shock system in combination with available technology for focused and controlled hyperthermia suggests heat-regulated transcription control as a promising tool for this purpose. We investigated the feasibility of a short fragment of the human hsp70B' promoter, with and without upstream insulator elements, for the regulation of transgene expression by replication-deficient or oncolytic adenoviruses. Two novel adenoviral vectors with an insulated hsp70B' promoter were developed and showed stringent heat-inducible gene expression with induction ratios up to 8000-fold. In contrast, regulation of gene expression from the hsp70B' promoter without insulation was suboptimal. In replication-competent/oncolytic adenoviruses regulation of the hsp70B' promoter was lost specifically during late replication in permissive cells and could not be restored by the insulators. We developed novel adenovirus gene transfer vectors that feature improved and stringent regulation of transgene expression from the hsp70B' promoter using promoter insulation. These vectors have potential for gene therapy applications that benefit from external modulation of therapeutic gene expression or for combination therapy with hyperthermia. Furthermore, our study reveals that vector replication can deregulate inserted cellular promoters, an observation which is of relevance for the development of replication-competent/oncolytic gene transfer vectors.

About 10 4 charm decays have been reconstructed from first-run data of Fermilab experiment E687 using the Fermilab Wide-Band Photon Spectrometer with the world's highest energy photon beam. The success of techniques for isolating and reconstructing charm event samples based on two complementary vertexing strategies is illustrated. Preliminary results are presented. These include lifetime value of (0.50 ± 0.06 ± 0.03)ps for the D s + , and (0.20 ± 0.03 ± 0.03)ps for the Λ c + . Preliminary values for the D + and D 0 lifetimes are consistent with currently accepted world averages. Signals for the Cabibbo-suppressed decays D 0 → π + π - π + π - , D + → K + K - π + , and D + → φπ + are shown; for B(D 0 → π + π - π + π - )/B(D 0 → K - π + π + π - ) our preliminary value is 0.10 ± 0.02 ± 0.02. Preliminary values for ratios B(D 0 → Kstring 0 K + K - )/B(D 0 → Kstring 0 π + π - ) and B(D 0 → Kstring 0 φ)/B(D 0 → Kstring 0 π + π - ) are 0.20 ± 0.06 and 0.16 ± 0.06. Preliminary results are given for cross sections of D* ± and D ± photoproduction on a Be target for the p 2 τ dependence of D minus-plus photoproduction and for the ratios D double-prime/D* + and D* - /D minus-plus . The energy dependence of the total open charm photoproduction cross section is compared with model predictions for photon energies up to 350 GeV. 18 refs., 5 figs

The drift velocity of electrons in water vapour at low values of E/N

Cheung, B.; Elford, M.T.

1990-01-01

The drift velocity of electrons in water vapour at 294 K has been measured over the E/N range 1.4 to 40 Td with an error estimated to be 35 Td. The present data show that μN decreases monotonically with decreasing E/N at low E/N values as observed by Wilson et al. (1975) and does not become independent of E/N as indicated by Lowke and Rees (1963). The present values although lower than those of Lowke and Rees, lie within the combined error limits, except for values below 2 Td. The present data suggested that the momentum transfer cross section at low energies is approximately 10% larger than that obtained by Pack et al. (1962) from their drift velocity measurements. 13 refs., 2 tabs., 5 figs

The rapidly evolving centromere-specific histone has stringent functional requirements in Arabidopsis thaliana.

Centromeres control chromosome inheritance in eukaryotes, yet their DNA structure and primary sequence are hypervariable. Most animals and plants have megabases of tandem repeats at their centromeres, unlike yeast with unique centromere sequences. Centromere function requires the centromere-specific histone CENH3 (CENP-A in human), which replaces histone H3 in centromeric nucleosomes. CENH3 evolves rapidly, particularly in its N-terminal tail domain. A portion of the CENH3 histone-fold domain, the CENP-A targeting domain (CATD), has been previously shown to confer kinetochore localization and centromere function when swapped into human H3. Furthermore, CENP-A in human cells can be functionally replaced by CENH3 from distantly related organisms including Saccharomyces cerevisiae. We have used cenh3-1 (a null mutant in Arabidopsis thaliana) to replace endogenous CENH3 with GFP-tagged variants. A H3.3 tail domain-CENH3 histone-fold domain chimera rescued viability of cenh3-1, but CENH3's lacking a tail domain were nonfunctional. In contrast to human results, H3 containing the A. thaliana CATD cannot complement cenh3-1. GFP-CENH3 from the sister species A. arenosa functionally replaces A. thaliana CENH3. GFP-CENH3 from the close relative Brassica rapa was targeted to centromeres, but did not complement cenh3-1, indicating that kinetochore localization and centromere function can be uncoupled. We conclude that CENH3 function in A. thaliana, an organism with large tandem repeat centromeres, has stringent requirements for functional complementation in mitosis.

Effective diffusion coefficients and porosity values for argillaceous rocks and bentonite: measured and estimated values for the provisional safety analyses for SGT-E2

2014-11-01

In Stage 2 of the Sectoral Plan for Deep Geological Repositories, safety analyses have to be performed. Geochemical parameters describing the transport and retardation of radionuclides in the argillaceous rocks considered and in compacted bentonite are required. In the present report, diffusion parameters for all clay host rocks, confining units and compacted bentonite are derived. Diffusion of tritiated water (HTO), "3"6Cl"- and "2"2Na"+ was studied. The measurements gave values for effective diffusion coefficients (D_e) and diffusion accessible porosities. The general observed trend "N"aD_e > "H"T"OD_e > "C"lD_e is in agreement with the expected behaviour of the three species in clay materials: ion exchanging cations show an enhanced mobility due to surface diffusion effects and anions are slowed down due to anion exclusion. Due to the negatively charged clay surfaces, anionic species are repelled from these surfaces resulting in an accessible porosity that is smaller than the total porosity as measured with HTO. The effect of porewater composition on the diffusion of HTO, "3"6Cl"- and "2"2Na"+ in Opalinus Clay was investigated. For ionic strength (IS) values between 0.17 M and 1.07 M, no significant effect on D_e could be observed. In the case of "3"6Cl"-, no effect on the accessible porosity was observed. The anion diffusion accessible porosity equals 50-60 % of the total porosity, independent on the ionic strength of the porewater. The diffusion parameters were measured on sedimentary rocks such as chalk, clay and limestone rocks. All data could be described by one single modified version of Archie's relation (extended Archie's relation). For values of porosity greater than about 0.1, the classical Archie's relation was valid. For values smaller than 0.1, the data deviated from the classical Archie's relation; this can be explained by additional changes of tortuosity with porosity values. At high porosity values (low density rocks), the microfabric of the clay

The five-fold differential cross section for the 12C(e,e'p)11B reaction was determined over a missing momentum range of 200-400 MeV/c, in a kinematics regime with Bjorken x > 1 and Q2 = 2.0 (GeV/c)2. A comparison of the results and theoretical models and previous lower missing momentum data is shown. The theoretical calculations agree well with the data up to a missing momentum value of 325 MeV/c and then diverge for larger missing momenta. The extracted distorted momentum distribution is shown to be consistent with previous data and extends the range of available data up to 400 MeV/c.

Measuring Values in Environmental Research: A Test of an Environmental Portrait Value Questionnaire

Science.gov (United States)

Bouman, Thijs; Steg, Linda; Kiers, Henk A. L.

2018-01-01

Four human values are considered to underlie individuals’ environmental beliefs and behaviors: biospheric (i.e., concern for environment), altruistic (i.e., concern for others), egoistic (i.e., concern for personal resources) and hedonic values (i.e., concern for pleasure and comfort). These values are typically measured with an adapted and shortened version of the Schwartz Value Survey (SVS), to which we refer as the Environmental-SVS (E-SVS). Despite being well-validated, recent research has indicated some concerns about the SVS methodology (e.g., comprehensibility, self-presentation biases) and suggested an alternative method of measuring human values: The Portrait Value Questionnaire (PVQ). However, the PVQ has not yet been adapted and applied to measure values most relevant to understand environmental beliefs and behaviors. Therefore, we tested the Environmental-PVQ (E-PVQ) – a PVQ variant of E-SVS –and compared it with the E-SVS in two studies. Our findings provide strong support for the validity and reliability of both the E-SVS and E-PVQ. In addition, we find that respondents slightly preferred the E-PVQ over the E-SVS (Study 1). In general, both scales correlate similarly to environmental self-identity (Study 1), energy behaviors (Studies 1 and 2), pro-environmental personal norms, climate change beliefs and policy support (Study 2). Accordingly, both methodologies show highly similar results and seem well-suited for measuring human values underlying environmental behaviors and beliefs. PMID:29743874

1996-01-01

A quantitative value-to-cost analysis was performed for the upstream technology portfolio of Mobil Oil for the period 1993 to 1998, by quantifying the cost of developing and delivering various technologies, including the net present value from technologies applied to thirty major assets. The value captured was classified into four general categories: (1) reduced capital costs, (2) reduced operating costs, (3) increased hydrocarbon production, and (4) increased proven reserves. The methodology used in quantifying the value-to-cost of upstream technologies and the results of asset analysis were described, with examples of value of technology to specific assets. A method to incorporate strategic considerations and business alignment to set overall program priorities was also discussed. Identifying and quantifying specific cases of technology application on an asset by asset basis was considered to be the principal advantage of using this method. figs

The primary objective of this study was to assess the expression of cyclin E in tumour tissues from 661 patients with epithelial ovarian tumours. The second was to evaluate whether cyclin E tissue expression levels correlate with clinico-pathological parameters and prognosis of the disease. Using...... tissue arrays (TA), we analysed the cyclin E expression levels in tissues from 168 women with borderline ovarian tumours (BOT) (147 stage I, 4 stage II, 17 stage III) and 493 Ovarian cancer (OC) patients (127 stage I, 45 stage II, 276 stage III, 45 stage IV). Using a 10% cut-off level for cyclin E......-off value showed that cyclin E had no independent prognostic value. In conclusion, we found cyclin E expression in tumour tissue to be of limited prognostic value to Danish OC patients....

2012-01-01

The aim of this study was to elucidate the distribution of estimated glomerular filtration rate (eGFR) values in patients who underwent gadolinium-based contrast agent (GBCA)-enhanced magnetic resonance imaging (MRI) at different types of hospitals. We retrospectively studied 2,550 patients who underwent MRI at five institutions. We recorded the date and value of each patient's eGFR test. The distribution of eGFR values was compared with that in the general Japanese population. A total of 84.3% of patients had their eGFRs evaluated before GBCA-enhanced MRI. Of these, 84.7% were evaluated within 3 months before the GBCA-enhanced MRI, and 1.3% were evaluated on the day of the GBCA-enhanced MRI. A total of 87.2% of patients tested had an eGFR of ≥60 ml/min/1.73 m 2 ; 12.8% had an eGFR of 2 , and no patients had an eGFR of 2 . The rate of renal function evaluation differed among hospitals. The prevalence of low eGFR values was greater in Juntendo Tokyo Koto Geriatric Medical Center than in the other hospitals, and the prevalence of low eGFR values was greater in patients who underwent GBCA-enhanced MRI than in the general Japanese population.

Attitudes toward older adults: A matter of cultural values or personal values?

2016-02-01

The current research aimed to address the inconsistent findings regarding cultural differences in attitudes toward older adults by differentiating the effects of personal and cultural values. In Study 1, we used data from the sixth wave of the World Values Survey to examine attitudes toward older adults across cultures, and how different personal values (i.e., communal vs. agentic) and cultural values (i.e., individualism) predicted these attitudes. The results of hierarchical linear modeling analyses showed that after controlling for potential covariates, personal communal values positively correlated with positive attitudes toward older adults; however, cultural individualistic values did not. To further examine the causal effects of personal values (vs. cultural values), we conducted an experimental study and confirmed that priming personal values rather than cultural values had significant effects on ageism attitudes. The present studies help to reconcile conflicting results on cultural differences in attitudes toward older adults. (c) 2016 APA, all rights reserved).

Lepton flavor violating decays τ→lll and μ→eγ in the Higgs triplet model

International Nuclear Information System (INIS)

Akeroyd, A. G.; Aoki, Mayumi; Sugiyama, Hiroaki

2009-01-01

Singly and doubly charged Higgs bosons in the Higgs triplet model mediate the lepton flavor violating (LFV) decays τ→lll and μ→eγ. The lepton flavor violating decay rates are proportional to products of two triplet Yukawa couplings (h ij ) which can be expressed in terms of the parameters of the neutrino mass matrix and an unknown triplet vacuum expectation value. We determine the parameter space of the neutrino mass matrix in which a signal for τ→lll and/or μ→eγ is possible at ongoing and planned experiments. The conditions for respecting the stringent upper limit for μ→eee are studied in detail, with emphasis given to the possibility of |h ee |≅0, which can only be realized if Majorana phases are present.

About 10 4 charm decays have been reconstructed from first-run data of Fermilab experiment E687 using the Fermilab Wide-Band Photon Spectrometer with the world's highest energy photon beam. Charm selection strategies and preliminary results are discussed. Lifetime values are (.50 ± .06 ± .03)ps for the D s + and (.20 ± .03 ± .03)ps for the Λ c + . Preliminary D + and D 0 lifetimes are consistent with current world averages. Signals for charm baryon and Cabibbo-suppressed charm meson decays are shown. Preliminary branching ratios are: B(D 0 → π + π - π + π - )/B(D 0 → K - π + π + π - ) = .10 ± .02 ± .02; B(D 0 → bar K 0 K + K - )/B(D 0 → bar K 0 π + π - ) = .20 ± .06(stat); B(D 0 → bar K 0 φ)/B(D 0 → bar K 0 π + π - ) = .16 ± .06(stat). Preliminary results are given on D* ± and D ±,0 photoproduction for photon energies from 100 to 350 GeV. 13 refs., 3 figs

Guidance for a personal target value of F(E)NO in allergic asthma: case report and theoretical example.

Science.gov (United States)

Högman, Marieann; Meriläinen, Pekka

2013-03-01

In clinically stable asthma the exhaled NO values (F(E)NO) are generally higher than in control subjects. Therefore, reference values are of limited importance in clinical practice. This is demonstrated in this case report, but it is also shown that NO parameters from non-linear modelling do have a clinical value. A subject with asthma was treated with inhaled corticosteroids for 1 week. The non-linear NO model was used to measure the response to treatment. The NO parameters from subjects with atopic rhinitis and asthma were fed into a computer program to generate theoretical F(E)NO₀.₀₅ values, i.e. target values. There was a dramatic decrease in F(E)NO₀.₀₅ due to treatment, from 82 to 34 ppb, but it remained higher than in healthy controls. This is due to the elevated diffusion rate of NO, unchanged by treatment. When the NO parameters are known, a personal best value of F(E)NO₀.₀₅ (fractional concentration of exhaled NO in the gas phase, 0.05 L/s) can be calculated, which can be the target value when only F(E)NO₀.₀₅ can be monitored. In conclusion, reference values for NO parameters are shown to be clinically useful. It is essential that every patient receives his/her target value of F(E)NO₀.₀₅, when only a single NO measurement is available. In our opinion, this is the reason why there are few successful studies of trying to target the NO value with inhaled corticosteroids.

We retrospectively studied 22 oligodendroglioma and 54 astrocytic tumor patients, including glioblastoma multiforme (GBM). The morphological tumor characteristics were evaluated using MR imaging. The rCBV, K{sup trans}, and V{sub e} values were recorded. All imaging and clinical values were compared. The ability to discriminate between the two entities was evaluated using receiver operating characteristic curve analyses. Separate comparison analysis between oligodendroglioma and astrocytic tumors excluding GBM was also performed. The presence of calcification, higher cortex involvement ratio, and lower V{sub e} value were more representative of oligodendrogliomas than astrocytic tumors (P = <0.001, 0.038, and <0.001, respectively). The area under the curve (AUC) value of a combination of calcification and cortex involvement ratio was 0.796. The combination of all three parameters, including V{sub e}, further increased the diagnostic performance (AUC = 0.881). Comparison test of the two AUC areas revealed significant difference (P = 0.0474). The presence of calcification and higher cortex involvement ratio were the only findings suggestive of oligodendrogliomas than astrocytic tumors with exclusion of GBMs (P = 0.014 and <0.001, respectively). Cortex involvement ratio and the presence of calcification with V{sub e} values were diagnostically accurate in identifying oligodendrogliomas. The V{sub e} value calculated from dynamic contrast-enhanced MR imaging could be a supportive tool for differentiating between oligodendrogliomas and astrocytic tumors including GBMs. (orig.)

Flavored e-cigarette use has risen rapidly, especially among young adults who also smoke cigarettes. We sought to determine whether flavoring enhances the subjective rewarding value, relative reinforcing value, and absolute reinforcing value of an e-cigarette with nicotine compared to an unflavored e-cigarette with nicotine. Using a within-subjects design, young adult smokers (n=32) participated in three human laboratory sessions. Session 1 evaluated the rewarding value of flavoring by having participants rate unflavored and flavored e-cigarettes with nicotine. Session 2 assessed the relative reinforcing value of a flavored vs unflavored e-cigarette via a choice task that evaluated the willingness to "work" to hit targets on a computer screen to earn flavored or unflavored e-cigarette puffs. Session 3 measured the absolute reinforcing value of flavored versus unflavored e-cigarettes via a 90-min ad-libitum vaping session where puffs from each e-cigarette were counted. Subjective reward value was higher for the flavored versus the unflavored e-cigarette (β=0.83, CI 0.35-1.32, p=0.001). Participants worked harder for flavored e-cigarette puffs versus unflavored e-cigarette puffs (breakpoint=5.7; 597 responses versus 127 responses; β=460.733, CI 246.58-674.88, pe-cigarettes with nicotine, and thus their abuse liability in young adult smokers. Further research is necessary to determine whether the use of flavoring in e-cigarettes impacts cigarette smoking behavior among young adults. Copyright © 2016 Elsevier Ireland Ltd.

We have studied the evolutionary stages of pure e-tailers, click & mortar (C&M) and brick & mortar (B&M) retailers for three points of time: June 1999, June 2000, and June 2001. To evaluate the dynamic stages of e-tailing business as an innovative venture, we propose four stages: exploration, breakeven, growth, and maturity. The stages are measured by the impact of revenue and income on the firm value, and a regression model is adopted to formulate the model. To empirically examine the stages...

We have evaluated the fibrinogen/fibrin fragment E antigen assay as a diagnostic test in patients with clinically suspected venous thrombosis by comparing the results of this assay with venography in 272 patients. The result of the fragment E antigen assay was elevated in 79 of 80 patients with positive venograms for recent venous thrombosis (sensitivity 99%) and within the normal range in 161 of 192 patients with normal venograms (specificity 84%). The fragment E assay was also evaluated in 130 medical and surgical controls without evidence of venous thrombosis by leg scanning and the test was found to be relatively nonspecific. However, in the patient group under study, a correct clinical diagnosis of no thrombosis, based on a normal fragment E result, was made in 161 of 162 cases (negative predictive value of 99%). Therefore, a normal test result effectively excludes a diagnosis of venous thrombosis in clinically symptomatic patients. The assay, as currently performed, is technically demanding and takes 24 hr to complete. Therefore, it will have to be simplified before it can be applied to clinical practice

To explore the value of human papillomavirus (HPV) E6/E7 and signal transducer and activator of transcription 3 (STAT3) mRNA detection in the screening of cervical lesions. 192 patients with abnormal ThinPrep cytology test (TCT) results and/or high-risk HPV infection were screened to identify possible cervical lesions in cases. Diagnoses were confirmed by histopathology. Fluorescence in situ hybridization (FISH) was performed to detect and qualify the mRNAs of HPV E6/E7, STAT3, and Survivin in cervical exfoliated cells. In addition, the performance of separate and combined mRNA detection methods were compared with TCT, HR-HPV DNA schemes respectively. 1. Compared with HPVE6/E7 and STAT3 mRNA methods, Survivin mRNA assay had poor specificity (Sp), Youden index (YI) and concordance rate. 2. HPV E6/E7, STAT3, and STAT3 + HR-HPV methods had the best Sp, concordance rate and positive predictive value (PPV) for cervical lesions screening and atypical squamous cells of undetermined significance (ASCUS) triage. For screening of high grade squamous intraepithelial lesions or greater (HSILs+), no difference was observed in the Se of mRNA detection methods in comparison with that of TCT, HR-HPV and TCT + HR-HPV, whereas the false positive rate (FPR) decreased by 41.48%/55.99%/17.19% and the colposcopy referral rate reduced by about 20.00%/25.00%/11.17%. For triage of women with ASCUS, no difference was observed in the Se of mRNA detection methods as compared to that of HR-HPV (χ 2  = 1.05, P > 0.75), while the FPR decreased by 45.83%/37.50%/41.66% and the colposcopy referral rate reduced by 32.42%/22.60%/25.28%, respectively. The Se, YI, and PPV of the combined methods increased in comparison to each method alone. 3. Compared with the TCT + HR-HPV method, HPV E6/E7 + STAT3 method had perfect Sp (95.92%) and PPV (95.40%) for screening HSILs+, the FPR and colposcopy referral rate decreased by 31.06% and 22.48% respectively. 1.

E-waste is a term used to cover items of all types of electrical and electronic equipment and its parts that have been discarded by the owners as waste without the intention of re-use, because this equipment has ceased to be of any value to its owners. E-waste is one of the fastestgrowing waste streams globally. Since the Rio Summit Earth summit organized by the United Nations in 1992, the concept of sustainability extends to rendering basic services such as Solid Waste Management and dealing with e-waste. People are afraid of e-waste because of its possible negative effects on health and because it could pollute the environment. Indicators of unsustainable service provision concerninge-waste include irregular collection, open dumping, burning of solid and e-waste in open spaces. Often collection covers a small part of the country, cost recovery is limited or not existent, and one notes poor utilization of available resources with no or very limited reuse and recycling

Reference values and evaluation of the results of intercomparisons

International Nuclear Information System (INIS)

Aigner, H.; Deron, S.; Kuhn, E.

1981-01-01

The need of a reference value for the composition of materials distributed in intercomparisons is generally recognized. A single reference laboratory or a group of reference laboratories may be used to establish this reference value. The respective advantages and limitations of the two approaches are discussed. The reference measurements must be evaluated to provide the confidence limits of the reference value but also an estimate of the possible heterogeneity of the materials and its samples. The results of the intercomparison measurements should themselves be evaluated to test and discuss the significance of the biases of individual and selected groups of laboratories or techniques. The approach taken by the Analytical Quality Control Services of the International Atomic Energy Agency is illustrated by the SR-1 intercomparison on uranium assay in UO 2 powder

The mass region 3.2 to 5.9 GeV was searched for evidence of narrow resonances in e + e - /sub f/ → hadron. No evidence was found for any such resonances other than the psi (3695) in this region with a sensitivity ranging from about 12 to 45 percent of the integrated cross section of the psi (3695). The more stringent bounds apply to resonances of a few MeV width, while the looser bounds apply to resonances of up to 20 MeV width. (U.S.)

The objective of the study was to discuss the findings of intraoperative electrically evoked auditory brainstem response (eABR) test results with a recently designed intracochlear test electrode (ITE) in terms of their relation to decisions of cochlear or auditory brainstem implantation. This clinical study was conducted in Hacettepe University, Department of Otolaryngology, Head and Neck Surgery and Department of Audiology. Subjects were selected from inner ear malformation (IEM) database. Eleven subjects with profound sensorineural hearing loss were included in the current study with age range from 1 year 3 months to 4 years 3 months for children with prelingual hearing loss. There was only one 42-year-old post-lingual subject. eABR was recorded with an ITE and intraoperatively with an original cochlear implant (CI) electrode in 11 cases with different IEMs. Findings of eABR with ITE and their relation to the decision for CI or auditory brainstem implant (ABI) are discussed. Positive eABR test results were found to be dependent on close to normal cochlear structures and auditory nerve. The probability of positive result decreases with increasing degree of malformation severity. The prediction value of eABR via ITE on decision for hearing restoration was found to be questionable in this study. The results of eABR with ITE have predictive value on what we will get with the actual CI electrode. ITE appears to stimulate the cochlea like an actual CI. If the eABR is positive, the results are reliable. However, if eABR is negative, the results should be evaluated with preoperative audiological testing and MRI findings.

Stringent complete response (sCR) criteria are used in multiple myeloma as a deeper response category compared with CR, but prospective validation is lacking, it is not always clear how evaluation of clonality is performed, and is it not known what the relative clinical influence is of the serum free light chain ratio (sFLCr) and bone marrow (BM) clonality to define more sCR. To clarify this controversy, we focused on 94 patients that reached CR, of which 69 (73%) also fulfilled the sCR criteria. Patients with sCR displayed slightly longer time to progression (median, 62 vs 53 months, respectively; P = .31). On analyzing this contribution to the prognosis of sFLCr or clonality, it was found that the sFLCr does not identify patients in CR at distinct risk; by contrast, low-sensitive multiparametric flow cytometry (MFC) immunophenotyping (2 colors), which is equivalent to immunohistochemistry, identifies a small number of patients (5 cases) with high residual tumor burden and dismal outcome; nevertheless, using traditional 4-color MFC, persistent clonal BM disease was detectable in 36% of patients, who, compared with minimal residual disease-negative cases, had a significantly inferior outcome. These results show that the current definition of sCR should be revised. © 2015 by The American Society of Hematology.

The thyroid imaging reporting and data system (TIRADS) and Bethesda system for reporting thyroid cytopathology (BSRTC) have been used for interpretation of ultrasound and fine-needle aspiration cytology (FNAC) results of thyroid nodules. BRAF(V600E) mutation analysis is a molecular tool in diagnosing thyroid carcinoma. Our objective was to compare the diagnostic value of these methods in differentiating high-risk thyroid nodules. Total 220 patients with high-risk thyroid nodules were recruited in this prospective study. They all underwent ultrasound, FNAC and BRAF(V600E) mutation analysis. The sensitivity and specificity of TIRADS were 73.1% and 88.4%. BSRTC had higher specificity (97.7%) and similar sensitivity (77.6%) compared with TIRADS. The sensitivity and specificity of BRAF(V600E) mutation (85.1%, 100%) were the highest. The combination of BSRTC and BRAF(V600E) mutation analysis significantly increased the efficiency, with 97.8% sensitivity, 97.7% specificity. In patients with BSRTC I-III, the mutation rate of BRAF(V600E) was 64.5% in nodules with TIRADS 4B compared with 8.4% in nodules with TIRADS 3 or 4A (P value in differentiating high-risk thyroid nodules. The TIRADS is useful in selecting high-risk patients for FNAB and patients with BSRTC I-III for BRAF(V600E) mutation analysis.

A first analysis of a database of shared preclinical safety data for 1214 small molecule drugs and drug candidates extracted from 3970 reports donated by thirteen pharmaceutical companies for the eTOX project (www.etoxproject.eu) is presented. Species, duration of exposure and administration route data were analysed to assess if large enough subsets of homogenous data are available for building in silico predictive models. Prevalence of treatment related effects for the different types of findings recorded were analysed. The eTOX ontology was used to determine the most common treatment-related clinical chemistry and histopathology findings reported in the database. The data were then mined to evaluate sensitivity of established in vivo biomarkers for liver toxicity risk assessment. The value of the database to inform other drug development projects during early drug development is illustrated by a case study.

Economic analysis of the profitability of energy-saving architectural measures for the achievement of the EPB-standard

International Nuclear Information System (INIS)

Audenaert, A.; De Boeck, L.; Roelants, K.

2010-01-01

Energy efficiency in buildings has become a key goal of any energy policy. Europe relies on the Energy Performance of Buildings Directive (EPBD), which has been converted by Flanders into the 'Energy Performance and Interior Climate' (EPB). Taking into account this Flemish EPB-standard (in terms of maximum U-values, E-level and K-value), this study seeks the economically most profitable combination of insulation - facade, roof, floor and glazing - for the Flemish citizen. For this purpose, a scenario-analysis is conducted using the EPB-software Flanders and a self-designed Excel file. Based on some important profitability criteria, the most profitable combination is determined for three representative types of dwellings studied. The scenario-analysis generates some well-founded guidelines for the Flemish citizen when building a house. It shows that in order to ensure the maximum profitability from investment in insulation, the key factor for the semi-detached dwelling is the insulation of roof and floor, whereas for a detached dwelling the key factor is the insulation of facade and floor. As a subsidiary consideration, the study also indicates that the U-values resulting from the more stringent E-level are still not sufficiently stringent because the U-values obtained for the most profitable combination are far below their maximum value. The same consideration applies in the case of the K-value.

1993-12-01

The asymmetry of positrons in the K + → μ + ν, μ + → e + ν e ν-bar μ decay chain was measured in a search for right-handed weak currents in ΔS = 1 semi-leptonic decay. High-intensity low-background monoenergetic polarized muons of 236 MeV/c momentum resulting from kaon decay at rest were directly extracted from a primary production target which was hit by a proton beam of the KEK 12-GeV proton synchrotron. Muons were stopped in a pure-aluminum plate, and the energy-integrated asymmetry of the decay positrons with respect to the incoming muon direction was determined to high precision. The observed asymmetry yielded ξP μ = -0.9996 ± 0.0030(stat) ± 0.0048(sys). This result revealed no evidence of right-handed currents in this kaon-decay chain, and set a stringent bound on the mass of the right-handed weak boson. (author) 52 refs

The objective of this experiment was to evaluate the comparative value of cigarettes versus high dose e-cigarettes among nicotine-dependent cigarette smokers when compared with money or use of their usual cigarette brand. The experiment used a within-subject design with four sessions. After baseline assessment, participants attended two 15-min unrestricted smoking sessions: one cigarette smoking session and one e-cigarette smoking session. Participants then attended two multiple-choice procedure (MCP) sessions: a session comparing cigarettes and money and a session comparing e-cigarettes and money. Participants (n=27) had used cigarettes regularly, had never used e-cigarettes, and were not currently attempting to quit smoking. The sample consisted primarily of males (72%), with a mean age of 34 years. When given the opportunity to choose between smoking a cigarette or an e-cigarette, participants chose the cigarette 73.9% of the time. Findings from the MCP demonstrated that after the first e-cigarette exposure sessions, the crossover value for cigarettes ($3.45) was significantly higher compared with the crossover value for e-cigarettes ($2.73). The higher participant preference, self-reported smoking effects, and higher MCP crossover points indicate that cigarettes have a higher comparative value than high dose e-cigarettes among e-cigarette naive smokers.

Prospects of type-II seesaw models at future colliders in light of the DAMPE e+e- excess

Science.gov (United States)

Sui, Yicong; Zhang, Yongchao

2018-05-01

The DAMPE e+e- excess at around 1.4 TeV could be explained in the type-II seesaw model with a scalar dark mater D which is stabilized by a discrete Z2 symmetry. The simplest scenario is the annihilation D D →H++H- followed by the subsequent decay H±±→e±e±, with both the DM and triplet scalars roughly 3 TeV with a small mass splitting. In addition to the Drell-Yan process at future 100 TeV hadron colliders, the doubly charged components could also be produced at lepton colliders like ILC and CLIC in the off shell mode and mediate lepton flavor violating processes e+e-→ℓi±ℓj∓ (with i ≠j ). A wide range of parameter space of the type-II seesaw could be probed, which are well below the current stringent lepton flavor constraints.

The coplanar (e, 3e) relative cross sections for double ionization of argon have been measured at an electron impact energy of E 0 = 561.4 eV and under equal energy sharing among the two 'ejected' electrons, E b = E c = 9 eV. The scattering angle is fixed to θ a = 1.5 degrees, corresponding to a momentum transfer K=0.4 au to the target. The experimental results have been compared with calculations in the first Born approximation, which include only first-order processes in the target-projectile interaction. The comparison shows severe deviations between the experimental and theoretical results. These deviations are much larger than the ones previously observed in helium under comparable kinematics. To fill this gap between theory and experiment, a decisive improvement in the theory is needed. This can be achieved by improving the first-order calculations and by including higher-order processes such as the two-step mechanism, or even new mechanisms, for instance the simultaneous ejection of the pair of target electrons.

Stringent constraints on the dark matter annihilation cross section from subhalo searches with the Fermi Gamma-Ray Space Telescope

Energy Technology Data Exchange (ETDEWEB)

Berlin, Asher; Hooper, Dan

2014-01-01

The dark matter halo of the Milky Way is predicted to contain a very large number of smaller subhalos. As a result of the dark matter annihilations taking place within such objects, the most nearby and massive subhalos could appear as point-like or spatially extended gamma-ray sources, without observable counterparts at other wavelengths. In this paper, we use the results of the Aquarius simulation to predict the distribution of nearby subhalos, and compare this to the characteristics of the unidentified gamma-ray sources observed by the Fermi Gamma-Ray Space Telescope. Focusing on the brightest high latitude sources, we use this comparison to derive limits on the dark matter annihilation cross section. For dark matter particles lighter than ~200 GeV, the resulting limits are the strongest obtained to date, being modestly more stringent than those derived from observations of dwarf galaxies or the Galactic Center. We also derive independent limits based on the lack of unidentified gamma-ray sources with discernible spatial extension, but these limits are a factor of ~2-10 weaker than those based on point-like subhalos. Lastly, we note that four of the ten brightest high-latitude sources exhibit a similar spectral shape, consistent with 30-60 GeV dark matter particles annihilating to b quarks with an annihilation cross section on the order of sigma v ~ (5-10) x 10^-27 cm^3/s, or 8-10 GeV dark matter particles annihilating to taus with sigma v ~ (2.0-2.5) x 10^-27 cm^3/s.

Full Text Available O artigo explorou a associação entre atribuições de causas ao desemprego e valores pessoais. Participaram do estudo 205 pessoas empregadas e desempregadas. Utilizou-se uma escala de atribuição sobre as causas do desemprego baseada em Furnham (1982, o Perfil de Valores Pessoais (PVQ 21 - versão breve de Schwartz incluído no European Social Survey (ESS e um questionário sociodemográfico. Desempregados e empregados não diferem significativamente em relação às atribuições de causas do desemprego. Em relação aos valores, enquanto os desempregados apresentam valores de universalismo e benevolência, ligados à dimensão de autotranscedência, os trabalhadores empregados apresentam valores de segurança, ligados à dimensão de conservadorismo. Finalmente, encontrou-se uma associação significativa entre atribuições fatalistas e valores de tradição e segurança, entre atribuições sociais e valores de tradição, e entre atribuições individuais e valores de estimulação.This article explored the association between explanations of unemployment and values. 205 people - employed and unemployed - were part of the study. Furnham´s attribution scale on unemployment (1982 and a short version of Schwartz's. Portrait Value Questionnaire (PVQ 21 included in the European Social Survey (ESS, together with a social and demographic questionnaire were used. The conclusion was that employed and unemployed showed no differences in the attribution of causes for unemployment. In relation to values, unemployed showed differences in universalism and benevolence, linked to the domain of self-trascendence, whereas employed individuals had a greater attach to security values, linked to the domain of conservation. Finally, it was found a significant association between fatalistic attributions and security and tradition values, between tradition and social attributions and between stimulation and individualistic reasons for unemployment.

Great efforts have been put forward to determine the neutrino mass from tritium β decay. The most prominent experimental setup, KATRIN, is expected to deliver an upper limit to the neutrino mass that is one order of magnitude more stringent than the current value by measuring the endpoint and the shape of the β spectrum of the tritium decay. The endpoint energy (assuming zero neutrino mass) can also be deduced from the Q-value of the decay by measuring the mass difference of tritium and the daughter {sup 3}He using high-resolution mass spectrometry. Such a measurement would give an excellent, independent calibration point for the KATRIN experiment to deduce its systematics. Our mass-difference measurement utilizes the Tritium- Helium double Penning trap (THe-Trap) setup. Based on the anharmonic cyclotron frequency determination method pioneered at the University of Washington, Seattle, precision at the level of 1 part in 10{sup 11} in the T/{sup 3}He mass ratio is expected. In this contribution, I describe the motivation, the principle, current status, and expectations of the experiment.

Under the European Union (EU) Biocidal Products Directive 98/8/EC, comprehensive evaluations on substances of the Third Priority List were conducted until 31 July 2007. This list includes, among other categories, disinfectants for human hygiene (e.g., skin and surface disinfection). For environmental exposure assessment of biocides, the EU emission scenarios apply. Currently available default values for disinfectants are based on consumption data from not more than 8 hospitals and were originally assembled for other purposes. To revalidate these default values, a survey on annual consumption data was performed in 27 German hospitals. These data were analyzed to provide consumption data per bed and day and per nurse and day for particular categories of active ingredients and were compared with default values from the EU emission scenario documents. Although several deviations were detected, an overall acceptable correspondence between Emission Scenario Documents default values and the current survey data was found. (c) 2009 SETAC

This paper shows that the model-independent account of correlations in an interest rate process or a log-consumption growth process leads to declining long-term tails of discount curves. Under the assumption of an exponentially decaying memory in fluctuations of risk-free real interest rates, I derive the analytical expression for an apt value of the long run discount factor and provide a detailed comparison of the obtained result with the outcome of the benchmark risk-free interest rate models. Utilizing the standard consumption-based model with an isoelastic power utility of the representative economic agent, I derive the non-Markovian generalization of the Ramsey discounting formula. Obtained analytical results allowing simple calibration, may augment the rigorous cost-benefit and regulatory impact analysis of long-term environmental and infrastructure projects.

The study includes analyses of current technical state of radiodiagnostic equipment from the Public Medico-Sanitary Institution of Ministry of Health of Republic of Moldova (IMSP MS RM). The traditional radiodiagnostic apparatuses were morally and physically outrun at 96,6% (in regional MSPI - 93,5%), inclusive the dental one - 92,0% (in raional MSPI - 97,2%), X-Ray exam -100%, mobile - 84,1% etc. The exploitation of the traditional radiodiagnostic apparatuses with high degree of physical and moral wear essentially diminished the quality of profile investigation, creates premises for diagnostic error perpetrating, increase the collective ionizing irradiation of population etc. In recent years the subvention of MSPI HM RM with digital radiodiagnostic equipment was started. This process is very hard unfold because of grave socio-economic crises in Republic of Moldova. Despite these obstacles the subvention of MSPI HM RM with digital equipment represents a stringent necessity and a time request.

e+e- interactions at PETRA-PEP energies (12 to 36 GeV) provide clear tests for QCD. First, results concerning annihilation total cross-section and inclusive spectra, in particular scaling violation, are considered. Next, energy-energy correlations, which provide an interesting test of QCD in the leading logarithm approximation, are reviewed. The third part deals with 3-jet events interpreted as evidence for hard gluon bremsstrahlung, and with various problems occuring in the determination of ..cap alpha..sub(s). e+e- annihilation on top of narrow resonances (..gamma..), and deep inelastic electron-photon scattering, which allow important tests of the theory, are briefly considered in the last part.

Heliotron E results (1981-March 1988)

1988-01-01

The original proposal of heliotron configuration was made by Professor Uo. The experimental studies were started in 1959 by Heliotron A, and Heliotron B (1960), Heliotron C (1965), Heliotron D (1970), Heliotron DM (1975), Heliotron E (1980) and Heliotron DR (1981) followed for more than 25 years in order to establish the proof of the principle of heliotron configuration. In this way, the heliotron has become a promising candidate for toroidal magnetic fusion reactors. The Heliotron E results obtained in the Plasma Physics laboratory, Kyoto University, have been well accepted in the world fusion community. The data obtained in the Heliotron E are the basis for the design of a next large helical device in Japan. To commemorate the achievements of Professor Uo, the collection of all the papers concerning the Heliotron E that were published in various scientific journals from 1981 through March, 1988, including the proceedings of the European Physical Society Conference and the IAEA International Conference on Plasma Physics and Fusion Research is published. 74 papers are grouped into five categories: confinement and heating experiments, plasma-wall interaction studies, diagnostics, heating systems, and the theory related to stellarator/heliotron devices.

Detailed descriptions of implementation strategies are lacking, and there is a corresponding dearth of information regarding methods employed in implementation strategy development. This paper describes methods and findings related to the alpha testing of eLearning modules developed as part of the Housing First Technical Assistance and Training (HFTAT) program's development. Alpha testing is an approach for improving the quality of a product prior to beta (i.e., real world) testing with potential applications for intervention development. Ten participants in two cities tested the modules. We collected data through (1) a structured log where participants were asked to record their experiences as they worked through the modules; (2) a brief online questionnaire delivered at the end of each module; and (3) focus groups. The alpha test provided useful data related to the acceptability and feasibility of eLearning as an implementation strategy, as well as identifying a number of technical issues and bugs. Each of the qualitative methods used provided unique and valuable information. In particular, logs were the most useful for identifying technical issues, and focus groups provided high quality data regarding how the intervention could best be used as an implementation strategy. Alpha testing was a valuable step in intervention development, providing us an understanding of issues that would have been more difficult to address at a later stage of the study. As a result, we were able to improve the modules prior to pilot testing of the entire HFTAT. Researchers wishing to alpha test interventions prior to piloting should balance the unique benefits of different data collection approaches with the need to minimize burdens for themselves and participants.

Energy management in buildings is becoming more transactive. Pacific Northwest National Laboratory and the U.S. Department of Energy Building Technologies Office recently defined innovative use cases wherein market-like mechanisms are used to manage energy within buildings, between buildings, and between buildings and third-party entities, such as power utilities. A next step toward defining a set of transactive use cases in the buildings domain is to carefully diagram the corresponding business cases to capture details of transactions among all stakeholders and their economic value propositions. The principles of e3-value diagramming are applied in this report toward creating business value diagrams. These principles are extended to be consistent with Universal Modeling Language use-case diagrams. Example diagrams are presented for a subset of buildings-domain use cases that were introduced in an earlier Pacific Northwest National Laboratory report. The diagrams are intended to clearly represent an understanding of the transactions through which individual entities accumulate value in their respective use cases, and the diagrams should therefore support economic valuation studies. The report reviews some of the foundational principles of e3 value and includes authors’ insights concerning the formulation of these diagrams using Universal Modeling Language as a more systematic modeling approach.

Value Encounters - Modeling and Analyzing Co-creation of Value

Science.gov (United States)

Weigand, Hans

Recent marketing and management literature has introduced the concept of co-creation of value. Current value modeling approaches such as e3-value focus on the exchange of value rather than co-creation. In this paper, an extension to e3-value is proposed in the form of a “value encounter”. Value encounters are defined as interaction spaces where a group of actors meet and derive value by each one bringing in some of its own resources. They can be analyzed from multiple strategic perspectives, including knowledge management, social network management and operational management. Value encounter modeling can be instrumental in the context of service analysis and design.

Global climate change presents a two-pronged threat to coral reef ecosystems: increasing sea surface temperatures will increase the likelihood of episodic bleaching events, while increasing ocean carbon dioxide concentrations will change the carbonate chemistry that drives coral growth. Because coral reefs have important societal as well as ecological benefits, climate change mitigation policies that ameliorate these impacts may create substantial economic value. We present a model that evaluates both the ecological and the economic impacts of climate change on coral reefs in the United States. We use a coral reef mortality and bleaching model to project future coral reef declines under a range of climate change policy scenarios for south Florida, Puerto Rico and Hawaii. Using a benefits transfer approach, the outputs from the physical model are then used to quantify the economic impacts of these coral reef declines for each of these regions. We find that differing climate change trajectories create substantial changes in projected coral cover and value for Hawaii, but that the ecological and economic benefits of more stringent emissions scenarios are less clear for Florida and Puerto Rico. Overall, our results indicate that the effectiveness of climate change mitigation policies may be region-specific, but that these policies could result in a net increase of nearly $10 billion in economic value from coral reef-related recreational activities alone, over the 21st century.

Circuitry linking the global Csr and σE-dependent cell envelope stress response systems.

Science.gov (United States)

CsrA of Escherichia coli is an RNA-binding protein that globally regulates a wide variety of cellular processes and behaviors including carbon metabolism, motility, biofilm formation, and the stringent response. CsrB and CsrC are sRNAs that sequester CsrA, thereby preventing CsrA-mRNA interaction. RpoE (σ E ) is the extracytoplasmic stress response sigma factor of E. coli Previous RNA-seq studies identified rpoE mRNA as a CsrA target. Here we explored the regulation of rpoE by CsrA and found that CsrA represses rpoE translation. Gel mobility shift, footprint and toeprint studies identified three CsrA binding sites in the rpoE leader transcript, one of which overlaps the rpoE Shine-Dalgarno (SD) sequence, while another overlaps the rpoE translation initiation codon. Coupled in vitro transcription-translation experiments showed that CsrA represses rpoE translation by binding to these sites. We further demonstrate that σ E indirectly activates transcription of csrB and csrC , leading to increased sequestration of CsrA such that repression of rpoE by CsrA is reduced. We propose that the Csr system fine-tunes the σ E -dependent cell envelope stress response. We also identified a 51 amino acid coding sequence whose stop codon overlaps the rpoE start codon, and demonstrate that rpoE is translationally coupled with this upstream open reading frame (ORF51). Loss of coupling reduces rpoE translation by more than 50%. Identification of a translationally coupled ORF upstream of rpoE suggests that this previously unannotated protein may participate in the cell envelope stress response. In keeping with existing nomenclature, we name ORF51 as rseD , resulting in an operon arrangement of rseD-rpoE-rseA-rseB-rseC IMPORTANCE CsrA posttranscriptionally represses genes required for bacterial stress responses, including the stringent response, catabolite repression, and the RpoS (σ S )-mediated general stress response. We show that CsrA represses translation of rpoE , encoding the

Health significance and statistical uncertainty. The value of P-value.

The P-value is widely used as a summary statistics of scientific results. Unfortunately, there is a widespread tendency to dichotomize its value in "P0.05" ("statistically not significant"), with the former implying a "positive" result and the latter a "negative" one. To show the unsuitability of such an approach when evaluating the effects of environmental and occupational risk factors. We provide examples of distorted use of P-value and of the negative consequences for science and public health of such a black-and-white vision. The rigid interpretation of P-value as a dichotomy favors the confusion between health relevance and statistical significance, discourages thoughtful thinking, and distorts attention from what really matters, the health significance. A much better way to express and communicate scientific results involves reporting effect estimates (e.g., risks, risks ratios or risk differences) and their confidence intervals (CI), which summarize and convey both health significance and statistical uncertainty. Unfortunately, many researchers do not usually consider the whole interval of CI but only examine if it includes the null-value, therefore degrading this procedure to the same P-value dichotomy (statistical significance or not). In reporting statistical results of scientific research present effects estimates with their confidence intervals and do not qualify the P-value as "significant" or "not significant".

Value-Based Standards Guide Sexism Inferences for Self and Others.

2017-09-01

People often disagree about what constitutes sexism, and these disagreements can be both socially and legally consequential. It is unclear, however, why or how people come to different conclusions about whether something or someone is sexist. Previous research on judgments about sexism has focused on the perceiver's gender and attitudes, but neither of these variables identifies comparative standards that people use to determine whether any given behavior (or person) is sexist. Extending Devine and colleagues' values framework (Devine, Monteith, Zuwerink, & Elliot, 1991; Plant & Devine, 1998), we argue that, when evaluating others' behavior, perceivers rely on the morally-prescriptive values that guide their own behavior toward women. In a series of 3 studies we demonstrate that (1) people's personal standards for sexism in their own and others' behavior are each related to their values regarding sexism, (2) these values predict how much behavioral evidence people need to infer sexism, and (3) people with stringent, but not lenient, value-based standards get angry and try to regulate a sexist perpetrator's behavior to reduce sexism. Furthermore, these personal values are related to all outcomes in the present work above and beyond other person characteristics previously used to predict sexism inferences. We discuss the implications of differing value-based standards for explaining and reconciling disputes over what constitutes sexist behavior.

Neural evidence of motivational conflict between social values.

Motivational interdependence is an organizing principle in Schwartz's circumplex model of social values, which has received abundant cross-cultural support. We used fMRI to test whether motivational relations between social values predict different brain responses in a situation of choice between values. We hypothesized that differences in brain responses would become evident when the more important value had to be selected in pairs of congruent (e.g., wealth and success) as opposed to incongruent (e.g., curiosity and stability) values as they are described in Schwartz's model, because the former serve mutually facilitating motives, whereas the latter serve mutually inhibiting motives. Consistent with the model, choosing between congruent values led to longer response times and more activation in conflict-related brain regions (e.g., the supplementary motor area, dorsolateral prefrontal cortex) than selecting between incongruent values. These results provide novel neural evidence supporting the circumplex model's predictions about motivational interdependence between social values. In particular, our results show that the neural networks underlying social values are organized in a way that allows activation patterns related to motivational similarity between congruent values to be dissociated from those related to incongruent values.

Prominent features in the received 9.303-MHz signal were periodic Faraday fading of signal intensity at rates up to 13 Hz and a time of arrival delay between the O- and X-modes of up to 0.8 ms. Both features occurred when the satellite was above or south of the Ottawa transmitter. Ionospheric models for ray tracing were constructed using both International Reference Ionosphere (IRI profiles and local peak electron density values from ISIS ionograms. Values for fade rate and differential mode delay were computed and compared to the values observed in the ISIS II data. The computed values showed very good agreement to the observed values of both received signal parameters when the topside sounding foF2 values were used to scale IRI profiles, but not when strictly modelled IRI profiles were used. It was determined that the primary modifier of the received signal parameters was the foF2 density and not the shape of the profile. This dependence was due to refraction, at the 9.303-MHz signal frequency, causing the rays to travel larger distances near the peak density where essentially all the mode splitting occurred. This study should assist in interpretation of ePOP RRI data when they are available.

We report results from the analysis of the K{sup {+-}}{yields}{pi}{sup +}{pi}{sup -}e{sup {+-}}{nu} (K{sub e4}) decay by the NA48/2 collaboration at the CERN SPS, based on the total statistics of 1.13 million decays collected in 2003-2004. The hadronic form factors in the S- and P-wave and their variation with energy are obtained. The phase difference between the S- and P-wave states of the {pi}{pi} system is accurately measured and allows a precise determination of a{sub 0}{sup 0} and a{sub 0}{sup 2}, the I=0 and I=2 S-wave {pi}{pi} scattering lengths: a{sub 0}{sup 0}=0.2220 {+-}0.0128 {sub stat}{+-}0.0050{sub syst}{+-}0.0037{sub th}, a{sub 0}{sup 2}=-0.0432{+-}0.0086{sub stat}{+-}0.0034{sub syst}{+-}0.0028{sub th}. Combination of this result with the other NA48/2 measurement obtained in the study of K{sup {+-}}{yields}{pi}{sup 0}{pi}{sup 0}{pi}{sup {+-}} decays brings an improved determination of a{sub 0}{sup 0} and the first precise experimental measurement of a{sub 0}{sup 2}, providing a stringent test of Chiral Perturbation Theory predictions and lattice QCD calculations. Using constraints based on analyticity and chiral symmetry, even more precise values are obtained: a{sub 0}{sup 0}=0.2196{+-}0.0028{sub stat}{+-}0.0020{sub syst} and a{sub 0}{sup 2}=-0.0444{+-}0.0007{sub stat}{+-}0.0005{sub syst}{+-}0.0008{sub ChPT}.

The muon as a laboratory for studying charged lepton-flavour violation (cLFV) has proven to be one of the most sensitive areas to probe for 'New Physics', due to the muon's copious production rate and relatively long lifetime. The search at the intensity frontier with precision-type experiments is complementary to the search for new particles at the high-energy frontier of TeV colliders. Of the three 'golden' muon channels: {mu} {yields} e{gamma}, {mu} {yields} 3e and {mu} {yields} econversion, an overview of the status of the coincidence experiments MEG, together with the latest results, which constitute the most stringent limit to date on this decay and the recently initiated Mu3e experiment, will be given.

Implications of results from the CERN e+e- collider LEP for SO(10) grand unification with two intermediate stages

We consider the breaking of the grand unification group SO(10) to the standard model gauge group through several chains containing two intermediate stages. Using the values of the gauge coupling constants at a scale M Z derived from recent data from the CERN e + e- collider LEP, we determine the range of their intermediate and unification scales. In particular, we identify those chains that permit new gauge structure at relatively low energy (∼1 TeV)

In the second part, upper limits on the dark matter annihilation cross-section into electron-positron pairs are obtained by combining observed data at different wavelengths (from Haslam, WMAP, and Fermi all-sky intensity maps) with recent measurements of the electron and positron spectra in the solar neighbourhood by PAMELA, Fermi, and H.E.S.S. We consider synchrotron emission in the radio and microwave bands, as well as inverse Compton scattering and final-state radiation at gamma-ray energies. For most values of the model parameters, the tightest constraints are imposed by the local positron spectrum and synchrotron emission from the central regions of the Galaxy. According to our results, the annihilation cross-section should not be higher than the canonical value for a thermal relic if the mass of the dark matter candidate is smaller than a few GeV. In addition, we also derive a stringent upper limit on the inner logarithmic slope α of the density profile of the Milky Way dark matter halo (α dm dm dm e ± =3 x 10 -26 cm 3 s -1 , as predicted for thermal relics from the big bang.

In Part I of this series, I introduced the concept of memes (1). Memes are ideas or concepts, the information world equivalent of genes. The goal of this series of articles is to infect you with my memes, so that you will assimilate, translate, and express them. We discovered that no matter what our area of expertise or "-ology," we all are in the information business. Our goal is to be in the wisdom business. We saw that when we convert raw data into wisdom we are moving along a value chain. Each step in the chain adds a different amount of value to the final product: timely, relevant, accurate, and precise knowledge which can then be applied to create the ultimate product in the value chain: wisdom. In Part II of this series, I infected you with a set of memes for measuring the cost of adding value (2). In Part III of this series, I infected you with a new set of memes for measuring the added value of knowledge, i.e., intellectual capital (3). In Part IV of this series, I will infect you with memes for measuring the value of people, structural, and customer capital.

Humans receive multiple benefits from various landscapes that foster ecological services and aesthetic attractiveness. In this study, a hybrid framework was proposed to evaluate ecological and aesthetic values of five landscape types in Houguanhu Region of central China. Data from the public aesthetic survey and professional ecological assessment were converted into a two-dimensional coordinate system and distribution maps of landscape values. Results showed that natural landscapes (i.e. water body and forest) contributed positively more to both aesthetic and ecological values than semi-natural and human-dominated landscapes (i.e. farmland and non-ecological land). The distribution maps of landscape values indicated that the aesthetic, ecological and integrated landscape values were significantly associated with landscape attributes and human activity intensity. To combine aesthetic preferences with ecological services, the methods (i.e. field survey, landscape value coefficients, normalized method, a two-dimensional coordinate system, and landscape value distribution maps) were employed in landscape assessment. Our results could facilitate to identify the underlying structure-function-value chain, and also improve the understanding of multiple functions in landscape planning. The situation context could also be emphasized to bring ecological and aesthetic goals into better alignment.

We present the results of a search for transversely polarised hidden photons (HPs) with ∝3 eV energies emitted from the Sun. These hypothetical particles, known also as paraphotons or dark sector photons, are theoretically well motivated for example by string theory inspired extensions of the Standard Model. Solar HPs of sub-eV mass can convert into photons of the same energy (photon<->HP oscillations are similar to neutrino flavour oscillations). At SHIPS this would take place inside a long light-tight high-vacuum tube, which tracks the Sun. The generated photons would then be focused into a low-noise photomultiplier at the far end of the tube. Our analysis of 330 h of data (and 330 h of background characterisation) reveals no signal of photons from solar hidden photon conversion. We estimate the rate of newly generated photons due to this conversion to be smaller than 25 mHz/m 2 at the 95%C.L. Using this and a recent model of solar HP emission, we set stringent constraints on χ, the coupling constant between HPs and photons, as a function of the HP mass.

Full Text Available Purpose - This study aims to examine the antecedents of perceived value in the Airbnb context using the variables of perceived benefits (i.e. monetary saving, hedonic benefit, novelty and social interaction and perceived risks (i.e. performance, physical, psychological and time. Design/methodology/approach - The study population was Airbnb users in South Korea. This study applied a survey research method using a questionnaire. A link to the survey was sent via e-mail to panel members of a multinational research company. Findings - The results revealed the positive influence of monetary saving, hedonic benefit and novelty on perceived value and the negative influence of psychological risk on perceived value. Research limitations/implications - The results of this study, which identified the specific factors that influence Airbnb users’ perception of value, can assist Airbnb managers and Airbnb hosts in developing appropriate marketing plans and strategies to enhance the value of their offerings. Originality/value - This study provided empirical support to the inclusion of affective factors and risk in determining perceived value. Moreover, while previous Airbnb studies focused on consumers from Western countries (e.g. USA and Canada, this study used a sample of South Korean consumers.

The Potential Value of Evaluation as Budgeting Tool for South African Municipalities

Directory of Open Access Journals (Sweden)

Malefetsane A. Mofolo

2016-03-01

Full Text Available The paradox around performance in the South African municipalities is undoubtedly exposed by the released reports of the Auditor-General for 2012/13 and Statistics South Africa’s Non-Financial Census of Municipalities, 2013. On the analyses of these reports, it became clear that municipalities could achieve more if stringent measures could be put in place and implemented to ensure that resources are used efficiently and effectively. To that effect, this article argues that monitoring and evaluation (M&E policy framework should be fully implemented in South African municipalities. This argument emanates from the fact that exorbitant amounts are incurred on fruitless and wasteful expenditure in municipalities. This article then presents a compelling case through which maximisation of expenditure prioritisation in municipalities is warranted. To investigate the concept of expenditure prioritisation, as a principle that municipalities should espouse, the study embarks on literature review as a method deemed suitable to explore the value of evaluation as budgeting tool for South African municipalities.  The findings to this investigation, recommended that on-going or process evaluation should be more useful to inform budget decision makers in the provincial and national governments about the required capacity interventions, which could assist to deal with financial weaknesses in municipalities.

Sandars, P.G.H.; Sternheimer, R.M.

1975-01-01

Some time ago, an accurate upper limit on a possible permanent electric dipole moment of the thallium atom in the 6 2 P 1 / 2 ground state was obtained by Gould. The result was D/sub Tl/ = [(1.3 +- 2.4) x 10 -21 cm]e. In connection with this value, a calculation of the electric dipole enhancement factor R/sub Tl/, which is defined as the ratio D/sub Tl//D/sub e/, where D/sub e/is the corresponding upper limit on a possible electric dipole moment of the (valence) electron was carried out. A value R/subTl/ = 700 was obtained, which leads to an upper limit D/sub e/ = [(1.9 +- 3.4) x 10 -24 cm]e. This result is comparable with the value D/sub e/ -24 cm)e previously obtained by Weisskopf et al. from measurements on the cesium atom, and with the result of Player and Sandars of [(0.7 +- 2.2) x 10 -24 cm]e obtained from the search for an electric dipole moment in the 3 P 2 metastable state of xenon. All three results set a stringent upper limit on the amount of a possible violation of T and P invariance in electromagnetic interactions. (U.S.)

Full Text Available Objective ‐ This study seeks to highlight the profound effect of Customer Value Discovery research on the internal business processes of two university libraries in the areas of cataloguing and acquisitions.Methods ‐ In this project, “Customer Discovery Workshops” with academic staff, students, and university stakeholders provided library managers and staff with information on what services and resources were of value to customers. The workshops also aimed to discover what features of existing library services and resources irritated the students, staff, and faculty. A student satisfaction survey assessed longer‐term impact of library changes to students in one university.Results ‐ The findings resulted in significant changes to collection development, acquisitions, and cataloguing processes. A number of value added services were introduced for the customer. The project also resulted in greater speed and efficiency in dealing with collection development, acquisitions, and cataloguing by the introduction of more technology‐enhanced services. Overall customer satisfaction was improved during the project period.Conclusion ‐ The changes to services introduced as a result of customer feedback also improved relationships between librarians and their university community, through the introduction of a more proactive and supportive service.

A production-theory-based framework for analysing recycling systems in the e-waste sector

International Nuclear Information System (INIS)

Schmidt, Mario

2005-01-01

Modern approaches in the production theory of business and management economics propose that objects (e.g. materials) be divided into good, bad or neutral. In transformation processes such as occur in production or recycling this makes it possible to distinguish stringently between the economic revenue of a process and the economic and ecological expenditures for it. This approach can be transferred to entire systems of processes in order to determine the system revenue and the system expenditure. Material flow nets or graphs are used for this purpose. In complex material flow systems it becomes possible to calculate not only the costs, but also the direct and indirect environmental impacts of an individual process or a system revenue (for example a product or the elimination of waste) consistently. The approach permits a stringent analysis as well as different analysis perspectives of a material flow system. It is particularly suitable for closed-loop economic systems in which material backflows occur. With the aid of an example developed jointly with Hewlett Packard Europe, the paper outlines how this approach can be employed in the field of e-waste management

Os resultados mostram que as representações dos estudantes sobre o envolvimento nos DHs envolvem quatro princípios organizadores: pessoal-abstrato; pessoal-concreto; governamental-abstrato; governamental-concreto. Em relação à ancoragem social dos princípios organizadores do envolvimento nos DHs, observou-se que os valores pós-materialistas se relacionaram positivamente com o envolvimento pessoal-abstrato, enquanto a adesão aos valores religiosos implicou maior envolvimento no princípio pessoal-concreto. Além disso, a adesão aos valores materialistas levou a uma avaliação mais positiva do envolvimento do Governo Brasileiro nos DHs, ao passo que os valores pós-materialistas contribuíram com uma avaliação mais crítica desse governo.

Full Text Available Breeding cassava relies on several selection stages (single row trial-SRT; preliminary; advanced; and uniform yield trials - UYT. This study uses data from 14 years of evaluations. From more than 20,000 genotypes initially evaluated only 114 reached the last stage. The objective was to assess how the data at SRT could be used to predict the probabilities of genotypes reaching the UYT. Phenotypic data from each genotype at SRT was integrated into the selection index (SIN used by the cassava breeding program. Average SIN from all the progenies derived from each progenitor was then obtained. Average SIN is an approximation of the breeding value of each progenitor. Data clearly suggested that some genotypes were better progenitors than others (e.g. high number of their progenies reaching the UYT, suggesting important variation in breeding values of progenitors. However, regression of average SIN of each parental genotype on the number of their respective progenies reaching UYT resulted in a negligible coefficient of determination (r2 = 0.05. Breeding value (e.g. average SIN at SRT was not efficient predicting which genotypes were more likely to reach the UYT stage. Number of families and progenies derived from a given progenitor were more efficient predicting the probabilities of the progeny from a given parent reaching the UYT stage. Large within-family genetic variation tends to mask the true breeding value of each progenitor. The use of partially inbred progenitors (e.g. S1 or S2 genotypes would reduce the within-family genetic variation thus making the assessment of breeding value more accurate. Moreover, partial inbreeding of progenitors can improve the breeding value of the original (S0 parental material and sharply accelerate genetic gains. For instance, homozygous S1 genotypes for the dominant resistance to cassava mosaic disease could be generated and selected. All gametes from these selected S1 genotypes would carry the desirable allele

Allergen-specific immunotherapy for house-dust mite (HDM) allergies is associated with lower success rates when compared with similar treatments for other inhalant allergens, such as grass or birch. One reason might be the greater difficulty in diagnosing patients with assumed HDM allergies because symptoms occur perennially and may differ from those of a conventional allergic rhinitis. The aim of the study was to compare the different methods of diagnosis in patients with assumed HDM allergy. We performed a retrospective analysis of nasal provocation tests (NPT) from patients (n = 161) evaluated for Dermatophagoides pteronyssinus (n = 127) and Dermatophagoides farinae (n = 104) allergies, and compared the results with other allergen testing methods (skin-prick test [SPT], intracutaneous test, and allergen specific immunoglobulin E levels [sIgE] to detect sensitization). Receiver operating characteristic curves were used for the analyses and the areas under the curve were calculated. For D. pteronyssinus and D. farinae, 86 and 70 complete data files, respectively, were available. For both tested HDMs, the results of the receiver operating characteristic curves showed a significant correlation for SPT and sIgE, with the results of the NPT (area under the curve, 0.742 to 0.763) but not for the intracutaneous test. In patients with a positive SPT (≥3 mm), an allergy was confirmed by the NPT in 69% of cases for D. pteronyssinus and 71% for D. farinae. A positive sIgE result (ImmunoCAP class of ≥2) was verified by the NPT in 69% of cases (D. pteronyssinus) and 70% (D. farinae). The predictability value for a positive NPT result is best for SPT and sIgE. Nevertheless, even if the results of both test systems are combined, the positive predictive value that was achieved was only 0.77 for D. pteronyssinus and 0.69 for D. farinae. Therefore, in patients eligible for immunotherapy for HDM, an NPT should be performed before the start of the therapy to verify a clinically

Management and financing of e-Government projects in India: Does financing strategy add value?

Full Text Available How do managers structure e-government projects and address challenges of risks, lack of technical expertise, and mitigation of strategic error for preventing loss of investments? Our aim was to compare the traditional finance approach and the strategy-driven, innovative financing approaches under the PPP model, to examine their managerial value-addition. We found that e-government projects require a carefully crafted structuring strategy and that innovative financing is more suitable in facilitating flexible decision making, building core capabilities, managing and sharing project risks, providing funds needed for growth and innovation, and customising tailor-made project governance strategy. Based on our findings, we develop five theoretical propositions.

Externalities - an analysis using the EU ExternE-results

International Nuclear Information System (INIS)

2003-10-01

The EU project ExternE quantified the externalities for the different energy technologies. In this work, the ExternE results are used in a MARKAL-analysis for the Nordic countries. The analysis does not go into detail, but gives some interesting indications: The external costs are not fully covered in the Nordic energy systems, the present taxes and charges are not high enough. The emissions from the energy systems would be strongly reduced, if taxes/environmental charges were set at the level ExternE calculate. The emissions from power production would be reduced most. Renewable energy sources and natural gas dominate the energy systems in the ExternE case

Consumer Complaints and Company Market Value

Danny Pimentel Claro

2014-07-01

Full Text Available Consumer complaints affect company market value and common sense suggests that a negative impact is expected. However, do complaints always negatively impact company market value? We hypothesize in this study that complaints may have a non-linear effect on market value. Positive (e.g. avoiding high costs to solve complaints and negative (e.g. speedy and intense diffusion tradeoffs may occur given the level of complaints. To test our non-linear hypothesis, a panel data was collected from cell phone service providers from 2005 to 2013. The results supported our tradeoff rationale. Low levels of complaints allow for companies to increase market value, while high levels of complaints cause increasing harm to market value. The sample, model and period considered in this study, indicates a level of 0.49 complaints per thousand consumers as the threshold for a shift in tradeoffs. The effects on market value become increasingly negative when trying to make reductions to move below this level, due to negative tradeoffs.

Search for lepton flavour violating decays of the Higgs boson to eτ and eμ in proton–proton collisions at s=8 TeV

2016-12-01

Full Text Available A direct search for lepton flavour violating decays of the Higgs boson (H in the H→eτ and H→eμ channels is described. The data sample used in the search was collected in proton–proton collisions at s=8 TeV with the CMS detector at the LHC and corresponds to an integrated luminosity of 19.7 fb−1. No evidence is found for lepton flavour violating decays in either final state. Upper limits on the branching fractions, B(H→eτ<0.69% and B(H→eμ<0.035%, are set at the 95% confidence level. The constraint set on B(H→eτ is an order of magnitude more stringent than the existing indirect limits. The limits are used to constrain the corresponding flavour violating Yukawa couplings, absent in the standard model.

Estimating the monetary value of willingness to pay for E-book reader's attributes using partially confounded factorial conjoint choice experiment

Science.gov (United States)

Yong, Chin-Khian

2013-09-01

A partially confounded factorial conjoint choice experiments design was used to examine the monetary value of the willingness to pay for E-book Reader's attributes. Conjoint analysis is an efficient, cost-effective, and most widely used quantitative method in marketing research to understand consumer preferences and value trade-off. Value can be interpreted by customer or consumer as the received of multiple benefits from a price that was paid. The monetary value of willingness to pay for battery life, internal memory, external memory, screen size, text to Speech, touch screen, and converting handwriting to digital text of E-book reader were estimated in this study. Due to the significant interaction effect of the attributes with the price, the monetary values for the seven attributes were found to be different at different values of odds of purchasing versus not purchasing. The significant interactions effects were one of the main contribution of the partially confounded factorial conjoint choice experiment.

Concurrent growth rate and transcript analyses reveal essential gene stringency in Escherichia coli.

Shan Goh

Full Text Available BACKGROUND: Genes essential for bacterial growth are of particular scientific interest. Many putative essential genes have been identified or predicted in several species, however, little is known about gene expression requirement stringency, which may be an important aspect of bacterial physiology and likely a determining factor in drug target development. METHODOLOGY/PRINCIPAL FINDINGS: Working from the premise that essential genes differ in absolute requirement for growth, we describe silencing of putative essential genes in E. coli to obtain a titration of declining growth rates and transcript levels by using antisense peptide nucleic acids (PNA and expressed antisense RNA. The relationship between mRNA decline and growth rate decline reflects the degree of essentiality, or stringency, of an essential gene, which is here defined by the minimum transcript level for a 50% reduction in growth rate (MTL(50. When applied to four growth essential genes, both RNA silencing methods resulted in MTL(50 values that reveal acpP as the most stringently required of the four genes examined, with ftsZ the next most stringently required. The established antibacterial targets murA and fabI were less stringently required. CONCLUSIONS: RNA silencing can reveal stringent requirements for gene expression with respect to growth. This method may be used to validate existing essential genes and to quantify drug target requirement.

A representation result for hysteresis operators with vector valued inputs and its application to models for magnetic materials

Energy Technology Data Exchange (ETDEWEB)

Klein, Olaf, E-mail: Olaf.Klein@wias-berlin.de

2014-02-15

In this work, hysteresis operators mapping continuous vector-valued input functions being piecewise monotaffine, i.e. being piecewise the composition of a monotone with an affine function, to vector-valued output functions are considered. It is shown that the operator can be generated by a unique defined function on the convexity triple free strings. A formulation of a congruence property for periodic inputs is presented and reformulated as a condition for the generating string function.

Extending Value Logic Thinking to Value Logic Portfolios

Based on value creation logic theory (Stabell & Fjeldstad, 1998), this paper suggests an extension of the original Stabell & Fjeldstad model by an additional fourth value logic, the value system logic. Furthermore, instead of only allowing one dominant value creation logic for a given firm...... or transaction, an understanding of firms and transactions as a portfolio of value logics (i.e. an interconnected coexistence of different value creation logics) is proposed. These additions to the original value creation logic theory imply interesting avenues for both, strategic decision making in firms...

Recent QCD results from ATLAS

CERN Document Server

Meyer, C; The ATLAS collaboration

2014-01-01

The ATLAS collaboration has performed studies of a wide range of QCD phenomena, from soft particle to hard photon and jet production. Recent soft-QCD measurements include studies of underlying event and vector meson production. Differential measurements of inclusive and dijet production provide stringent tests of high-order QCD predictions and provide input for determination of parton density functions. Measurements of isolated inclusive and di-photons cross sections for high transverse momentum photons test theoretical predictions of perturbative QCD and constrain parton density functions. An overview of these results is given.

Full Text Available This paper introduces a 43-level asymmetric uniform step cascaded multilevel inverter (CMLI that consists of four H-bridges per phase, with different dc sources of values E, 2E, 7E and 11E. A mixed integer linear programming (MILP optimization model is applied to determine the switching angles of the CMLI power switches that can minimize the values of any undesired harmonics. Single phase and three phase cases are considered. The results show very low values of all the undesired harmonics over wide voltage ranges, which agree with the IEEE standards 519-1992 for voltage distortion limits for both the values of %THDE and %VHmax so that no output filters are needed.

The value of innovation under value-based pricing

Science.gov (United States)

Moreno, Santiago G.; Ray, Joshua A.

2016-01-01

Objective The role of cost-effectiveness analysis (CEA) in incentivizing innovation is controversial. Critics of CEA argue that its use for pricing purposes disregards the ‘value of innovation’ reflected in new drug development, whereas supporters of CEA highlight that the value of innovation is already accounted for. Our objective in this article is to outline the limitations of the conventional CEA approach, while proposing an alternative method of evaluation that captures the value of innovation more accurately. Method The adoption of a new drug benefits present and future patients (with cost implications) for as long as the drug is part of clinical practice. Incidence patients and off-patent prices are identified as two key missing features preventing the conventional CEA approach from capturing 1) benefit to future patients and 2) future savings from off-patent prices. The proposed CEA approach incorporates these two features to derive the total lifetime value of an innovative drug (i.e., the value of innovation). Results The conventional CEA approach tends to underestimate the value of innovative drugs by disregarding the benefit to future patients and savings from off-patent prices. As a result, innovative drugs are underpriced, only allowing manufacturers to capture approximately 15% of the total value of innovation during the patent protection period. In addition to including the incidence population and off-patent price, the alternative approach proposes pricing new drugs by first negotiating the share of value of innovation to be appropriated by the manufacturer (>15%?) and payer (price that satisfies this condition. Conclusion We argue for a modification to the conventional CEA approach that integrates the total lifetime value of innovative drugs into CEA, by taking into account off-patent pricing and future patients. The proposed approach derives a price that allows manufacturers to capture an agreed share of this value, thereby incentivizing

1980-01-01

The experimental information on B(E2) transition rates in the yrast bands of doubly even nuclei (126 2 (J: moment of inertia) are plotted versus the rotational frequency squared h/2π 2 ω 2 for each nucleus. In strongly deformed nuclei (N >= 90), the Ssub(exp) curves smoothly increase for low rotational frequencies suggesting that up to spin values I approx. 8 the ratio Q 2 0 /J is nearly constant (Q 0 : quadrupole moment). This is not the case in nuclei with a soft core (N <= 88). In the relevant discussion, the hydrodynamical model as well as the CAP effect are considered. The results in the backbending region are qualitatively discussed in terms of the two-band crossing model. Evidence is found supporting the prediction of an oscillating behavior of the yrast-yrare interaction. (orig.)

Value and growth stocks in Brazil: risks and returns for one - and two-dimensional portfolios under different economic conditions Ações de valor e de crescimento no Brasil: riscos e retornos de carteiras uni e bidimensionais em diferentes estados da economia

Leandro da Rocha Santos

Full Text Available For empirical purposes, value stocks are usually defined as those traded at low price-to-earnings ratios (stock prices divided by earnings per share, low price-to-book ratios (stock prices divided by book value per share or high dividend yields (dividends per share divided by stock prices. Growth stocks, on the other hand, are traded at high price-to-earnings ratios, high price-to-book ratios or low dividend yields. Academic research so far produced, international and Brazilian alike, shows that value stocks outperform growth stocks, challenging the Efficient Market Hypothesis, which states that the market prices of traded stocks are the best estimate of their intrinsic values. Most studies use a single ratio to sort stocks on percentiles; risks (generally defined as beta or standard deviations and returns are then calculated for the resulting value and growth portfolios. In the present paper, we aim to further contribute to the growing literature on the field by applying a method not previously tested on the Brazilian market. We build portfolios sorted by the price-to-earnings and price-to-book ratios alone and by a combination of both in order to assess value and growth stocks' risks and returns on the Brazilian stock market between 1989 and 2009. Furthermore, our risk analysis may be regarded as the paper's main contribution, since its approach departs from conventional risk concepts, as we not only test for beta: portfolios' returns are measured under different economic conditions. Results support a pervasive value premium in the Brazilian stock market. Risk analysis shows that this premium holds under every economic condition analyzed, suggesting that value stocks are indeed less risky. Beta proved not to be a satisfactory risk measure. Portfolios sorted by the price-to-earnings ratio yielded the best results.Para fins de pesquisas empíricas, ações de valor são geralmente definidas como aquelas negociadas a baixos índices pre

Cultural estrangement: the role of personal and societal value discrepancies.

Science.gov (United States)

Bernard, Mark M; Gebauer, Jochen E; Maio, Gregory R

2006-01-01

Study 1 examined whether cultural estrangement arises from discrepancies between personal and societal values (e.g., freedom) rather than from discrepancies in attitudes toward political (e.g., censorship) or mundane (e.g., pizza) objects. The relations between different types of value discrepancies, estrangement, subjective well-being, and need for uniqueness also were examined. Results indicated that personal-societal discrepancies in values and political attitudes predicted estrangement, whereas mundane attitude discrepancies were not related to estrangement. As expected, value discrepancies were the most powerful predictor of estrangement. Value discrepancies were not related to subjective well-being but fulfilled a need for uniqueness. Study 2 replicated the relations between value discrepancies, subjective well-being, and need for uniqueness while showing that a self-report measure of participants' values and a peer-report measure of the participants' values yielded the same pattern of value discrepancies. Together, the studies reveal theoretical and empirical benefits of conceptualizing cultural estrangement in terms of value discrepancies.

Experimental tests of QCD: Deep inelastic scattering, e+e- annihilation and hard hadron-hadron scattering

International Nuclear Information System (INIS)

Hansl-Kozanecka, T.

1992-01-01

In this set of lectures the author examines phenomenological aspects of quantum chromodynamics (QCD) which are relevant for lepton-hadron, electron-positron, and hadron-hadron collisions. He points how the strength of the strong coupling constant, αs, makes QCD calculations converge much more slowly in powers of αs, and missing higher order terms must be carefully estimated. The most stringent test of QCD can be performed in deep inelastic lepton scattering and in e + e - annihilation. In deep inelastic scattering the virtual γ or W/Z are used as a probe of the nucleon structure. They couple to quarks, not gluons. Only the incoming and outgoing lepton have to be measured. The hadronic fluid state does not have to be analyzed. In e + e - annihilation the virtual γ or Z 0 decays to lepton and quark pairs. The branching ratio into quarks is a counter for the number of colours available, the detailed structure of the final state reflects the radiation of gluons as the initial quark-antiquark separate from each other. Quarks and gluons are observed here, though in the presence of hadron formation. Hard hadron-hadron, or parton-parton collisions provide cross sections dominated by the gluon component, which is only weakly measured in deep inelastic collisions. Recent experimental results in these three areas are reviewed, and compared to QCD calculations. Scaling violations and analysis of structure functions in deep inelastic scattering are reviewed. QCD in e + e - branching to hadrons is reviewed near the Z 0 resonance, and a number of cross sections and jet related properties which can be calculated as a function of the single parameter αs are reviewed. Hadron-hadron collisions are reviewed for three processes; jet production, direct photon production, and high p perpendicular W/Z boson production

Buckwheat (BW) is the source of a life-threatening allergen. Fag e 3-specific serum IgE (sIgE) is more useful than BW-sIgE for diagnosis; however, it is unknown whether Fag e 3-sIgE can predict oral food challenge (OFC) results and anaphylaxis. This study aimed to clarify the efficacy of Fag e 3-sIgE in predicting OFC results and anaphylaxis. We conducted a retrospective review of BW- and Fag e 3-sIgE data obtained using the ImmunoCAP® assay system and fluorescent enzyme-linked immunosorbent assay from children who underwent OFC using 3,072 mg of BW protein between July 2006 and March 2014 at Sagamihara National Hospital, Kanagawa, Japan. We analyzed 60 patients aged 1.9-13.4 years (median 6.0 years); 20 (33%) showed objective symptoms upon BW OFC. The patients without symptoms had significantly lower Fag e 3-sIgE than those with non-anaphylactic (p tested factor that significantly predicted positive OFC results (odds ratio 8.93, 95% confidence interval 3.10-25.73, p < 0.001) and OFC-induced anaphylaxis (2.67, 1.12-6.35, p = 0.027). We suggest that a threshold Fag e 3-sIgE level of 18.0 kUE/L has 95% probability of provoking a positive reaction to BW. Fag e 3-sIgE predicted OFC results and OFC-induced anaphylaxis. We further emphasize paying careful attention to the risk of BW OFC-induced anaphylaxis. © 2018 The Author(s) Published by S. Karger AG, Basel.

Results of an OECD/NEA comparison of minimum critical values

International Nuclear Information System (INIS)

Weber, Wolf; Mennerdahl, Dennis

2003-01-01

An OECD/NEA expert group has compiled international data on existing minimum critical values for UO 2 -, PuO 2 -, UNH- and PuNH-systems to identify any significant discrepancies in the data and to propose explanations. The paper examines the spread of the compiled data and the influence of the time of generation of the data on the spread. It turns out, that the remarkable spread reduces by omitting values older than five years. Considering only data generated in the last three years, the spread further reduces. The number of cases with a large spread in the reported minimum critical values falls from 28 to four cases, and the smallest and largest data values converge. (author)

Missing value imputation for epistatic MAPs

LENUS (Irish Health Repository)

Ryan, Colm

2010-04-20

Abstract Background Epistatic miniarray profiling (E-MAPs) is a high-throughput approach capable of quantifying aggravating or alleviating genetic interactions between gene pairs. The datasets resulting from E-MAP experiments typically take the form of a symmetric pairwise matrix of interaction scores. These datasets have a significant number of missing values - up to 35% - that can reduce the effectiveness of some data analysis techniques and prevent the use of others. An effective method for imputing interactions would therefore increase the types of possible analysis, as well as increase the potential to identify novel functional interactions between gene pairs. Several methods have been developed to handle missing values in microarray data, but it is unclear how applicable these methods are to E-MAP data because of their pairwise nature and the significantly larger number of missing values. Here we evaluate four alternative imputation strategies, three local (Nearest neighbor-based) and one global (PCA-based), that have been modified to work with symmetric pairwise data. Results We identify different categories for the missing data based on their underlying cause, and show that values from the largest category can be imputed effectively. We compare local and global imputation approaches across a variety of distinct E-MAP datasets, showing that both are competitive and preferable to filling in with zeros. In addition we show that these methods are effective in an E-MAP from a different species, suggesting that pairwise imputation techniques will be increasingly useful as analogous epistasis mapping techniques are developed in different species. We show that strongly alleviating interactions are significantly more difficult to predict than strongly aggravating interactions. Finally we show that imputed interactions, generated using nearest neighbor methods, are enriched for annotations in the same manner as measured interactions. Therefore our method potentially

New measurement of G_E/GM for the proton

Science.gov (United States)

Segel, Ralph

2003-10-01

Recent polarization transfer measurements of the ratio of the proton electric to magnetic form factor, G E /G_M, find μ_pG E /GM = 1 - 0.13Q ^2 while a long series of L-T separations are fit by μ_pG_E/GM ≈ 1. Jefferson Lab experiment E01-001 used a new technique for making L-T separations that greatly reduces the dominant systematic uncertainties present in previous determinations. Protons from ep scattering were measured over a wide range in ɛ at Q^2 = 2.64, 3.20 and 4.10 GeV^2 and, simultaneously, protons scattered at Q^2 = 0.5 GeV^2 were measured over a small range in ɛ. The Q^2 = 0.5 GeV^2 measurements provided an internal monitor and only kinematic factors and ratios of simultaneously measured cross sections enter into the determinations of G_E/G_M. Measuring the proton cross sections has the advantage that for the same Q^2, count rates change very little with ɛ and also proton momentum is the same at all ɛ thus eliminating the effect of any momentum-dependent inefficiencies. Neither of these is true for L-T separations performed by measuring electron cross sections. Furthermore, the radiative corrections for the proton cross sections are a factor of about 2.5 smaller. All previous L-T separations measured electron cross sections and none had the advantage of an internal monitor. Therefore, the results of E01-001 stringently test whether systematic uncertainties in previous L-T separations may have been sufficient to explain the discrepancy with the recent polarization transfer results.

Multi-valued fields

CERN Document Server

Ershov, Yuri L

2001-01-01

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

Stringent tests of constrained Minimal Flavor Violation through ΔF=2 transitions

International Nuclear Information System (INIS)

Buras, Andrzej J.; Girrbach, Jennifer

2013-01-01

New Physics contributions to ΔF=2 transitions in the simplest extensions of the Standard Model (SM), the models with constrained Minimal Flavor Violation (CMFV), are parametrized by a single variable S(v), the value of the real box diagram function that in CMFV is bounded from below by its SM value S 0 (x t ). With already very precise experimental values of ε K , ΔM d , ΔM s and precise values of the CP-asymmetry S ψK S and of B K entering the evaluation of ε K , the future of CMFV in the ΔF = 2 sector depends crucially on the values of vertical stroke V cb vertical stroke, vertical stroke V ub vertical stroke, γ, F B s √(B B s ) and F B d √(B B d ). The ratio ξ of the latter two non-perturbative parameters, already rather precisely determined from lattice calculations, allows then together with ΔM s / ΔM d and S ψK S to determine the range of the angle γ in the unitarity triangle independently of the value of S(v). Imposing in addition the constraints from vertical stroke ε K vertical stroke and ΔM d allows to determine the favorite CMFV values of vertical stroke V cb vertical stroke, vertical stroke V ub vertical stroke, F B s √(B B s ) and F B d √(B B d ) as functions of S(v) and γ. The vertical stroke V cb vertical stroke 4 dependence of ε K allows to determine vertical stroke V cb vertical stroke for a given S(v) and γ with a higher precision than it is presently possible using tree-level decays. The same applies to vertical stroke V ub vertical stroke, vertical stroke V td vertical stroke and vertical stroke V ts vertical stroke that are automatically determined as functions of S(v) and γ. We derive correlations between F B s √(B B s ) and F B d √(B B d ), vertical stroke V cb vertical stroke, vertical stroke V ub vertical stroke and γ that should be tested in the coming years. Typically F B s √(B B s ) and F B d √(B B d ) have to be lower than their present lattice values, while vertical stroke V cb vertical stroke has to

SU-E-I-27: Establishing Target Exposure Index Values for Computed Radiography

Murphy, N; Tchou, P; Belcher, K; Scott, A

2014-01-01

Purpose: To develop a standard set of target exposure index (TEI) values to be applied to Agfa Computed Radiography (CR) readers in accordance with International Electrotechnical Committee 62494-1 (ed. 1.0). Methods: A large data cohort was collected from six USAF Medical Treatment Facilities that exclusively use Agfa CR Readers. Dose monitoring statistics were collected from each reader. The data was analyzed based on anatomic region, view, and processing speed class. The Agfa specific exposure metric, logarithmic mean (LGM), was converted to exposure index (EI) for each data set. The optimum TEI value was determined by minimizing the number of studies that fell outside the acceptable deviation index (DI) range of +/− 2 for phototimed techniques or a range of +/−3 for fixed techniques. An anthropomorphic radiographic phantom was used to corroborate the TEI recommendations. Images were acquired of several anatomic regions and views using standard techniques. The images were then evaluated by two radiologists as either acceptable or unacceptable. The acceptable image with the lowest exposure and EI value was compared to the recommended TEI values using a passing DI range. Results: Target EI values were determined for a comprehensive list of anatomic regions and views. Conclusion: Target EI values must be established on each CR unit in order to provide a positive feedback system for the technologist. This system will serve as a mechanism to prevent under or overexposures of patients. The TEI recommendations are a first attempt at a large scale process improvement with the goal of setting reasonable and standardized TEI values. The implementation and effectiveness of the recommended TEI values should be monitored and adjustments made as necessary

Rayleigh-Taylor instability and resulting failure modes of ablatively imploded inertial fusion targets

International Nuclear Information System (INIS)

Montierth, L.; Morse, R.

1984-01-01

This chapter discusses small amplitude growth of the outside surface instability and modes of failure resulting from nonlinear development of the inside surface instability. It is demonstrated that pellets with initial pellet aspect ratio, A /SUB p/ >5 may have difficulty with Rayleigh-Taylor instability and that shells with A /SUB p/ greater than or equal to10 will probably demand stringent smoothness specification in order not to experience failure in the final implosion. The linear amplification of the outside surface instability can easily exceed 10 3 for A /SUB p/ and resulting A values in the range of programmatic interest. Amplifications of this order, starting from attainable surface finishes, can then penetrate to the inside shell surface, producing perturbations there which approach the nonlinear development amplitude and at the start of the final deceleration. It is shown that such inside surface perturbations can be amplified to large amplitude by the inside instability and cause failure through reduction of the maximum fuel temperature achieved. Insight into the scaling of failure mechanisms is offered

New Physics contributions to {Delta}F=2 transitions in the simplest extensions of the Standard Model (SM), the models with constrained Minimal Flavor Violation (CMFV), are parametrized by a single variable S(v), the value of the real box diagram function that in CMFV is bounded from below by its SM value S{sub 0}(x{sub t}).

Raw fruits and vegetables have been known to harbor pathogenic microorganisms such as Escherichia coli and Salmonella typhimurium. Associated diseases upon ingestion of contaminated fruits and vegetables include, but not limited to stomach cramps, diarrhea, vomiting and even kidney failure. Irradiation technology was proven to be an effective way of reducing and controlling pathogenic microorganisms in fruits and vegetables. The study was conducted to determine the D10 value of E.coli and S. typhimurium in pre-cut mixed vegetables and pre-cut mixed fruits, respectively, as an indicator of the effectiveness of gamma irradiation as an alternative treatment to improve the microbial safety and quality of fresh vegetables and fruits E. coli ATCC no.25922 and S. typhimurium ATCC No. 14028 were inoculated separately in ten (10) mL tryptic soy broth and incubated for 24 hrs at 37oC. Twenty five (25) grams of fresh pre-cut vegetables and pre-cut mixed fruits were inoculated separately with 0.5 mL cultured E. coli and 0.2 mL cultured S. typhimurium, respectively. The E. coli strains in fresh vegetable were exposed to irradiation doses of 0.2 to 0.8kGy. The samples were analyzed by making serial dilutions in sterile phosphate buffer using a petrifilm and tryptic soy agar according to the standards methodology describe in Bacteriological Analytical Manual (BAM). The D10 value of E. coli and S. typhimurium in fresh vegetables and mixed fruits were determined using linear regression analysis of the radiation dose with the log cfu/gm. The calculated D10 value ranged from 0.19 ± 0.02kGy and 0.22 ± 0.01kGy for pre-cut mixed vegetables and pre-cut mixed fruits, respectively. The results translate to irradiation dose of 1.0 kGy (5D10) to inactivate E. coli and S. typhimurium in mixed vegetables and fruits. (author)

Physicians' personal values in determining medical decision-making capacity: a survey study.

Science.gov (United States)

Hermann, Helena; Trachsel, Manuel; Biller-Andorno, Nikola

2015-09-01

Decision-making capacity (DMC) evaluations are complex clinical judgements with important ethical implications for patients' self-determination. They are achieved not only on descriptive grounds but are inherently normative and, therefore, dependent on the values held by those involved in the DMC evaluation. To date, the issue of whether and how physicians' personal values relate to DMC evaluation has never been empirically investigated. The present survey study aimed to investigate this question by exploring the relationship between physicians' value profiles and the use of risk-relative standards in capacity evaluations. The findings indicate that physicians' personal values are of some significance in this regard. Those physicians with relatively high scores on the value types of achievement, power-resource, face and conformity to interpersonal standards were more likely to apply risk-relative criteria in a range of situations, using more stringent assessment standards when interventions were riskier. By contrast, those physicians who strongly emphasise hedonism, conformity to rules and universalism concern were more likely to apply equal standards regardless of the consequences of a decision. Furthermore, it has been shown that around a quarter of all respondents do not appreciate that their values impact on their DMC evaluations, highlighting a need to better sensitise physicians in this regard. The implications of these findings are discussed, especially in terms of the moral status of the potential and almost unavoidable influence of physicians' values.

To gain a deeper understanding of the guiding core values that deans of academic medical centers (AMCs) considered most essential for their leadership and the major leadership challenges that confront them. In 2003-04, semistructured interviews of 18 deans at U.S. colleges of medicine or AMCs were organized around four dimensions: background, leadership challenges, organizational effectiveness, and systems enablers/restrainers for leadership. A values Q-sort was used to determine how widely core values were shared among deans and how the complex challenges they faced did or did not align with these values. Fourteen of the 18 (78%) deans identified financial difficulties as their most pressing leadership challenge, followed by weak institutional alignment (61%), staffing problems (33%), and poor morale (28%). Open, candid communication was reported as the most effective means of addressing these complex problems. Enacting espoused shared values and having a positive attitude were identified as the most important enablers of systemic leadership, whereas micromanagement and difficult people were the major restraints. Q-sort results on 38 positive leadership values indicated that participants considered integrity most essential. Integrity was positively correlated with humanistic values and negatively correlated with results. Vision, another highly espoused value, correlated strongly with performance-oriented values but correlated negatively with humanistic values. A dynamic tension exists in AMCs between humanistic values and performance-based core values. The ability to manage that tension (i.e., when to prioritize one set of values over the other) is inherent in a dean's work.

On expectation values for nuclear energy levels

The nuclear model is built up by constructing measured states, including the ground state, from the vacuum state. All states are, however, not accessible from the ground state so that selection rules may be found which at the same time impose even more stringent conditions on the labelling of energy levels. These are the subject of this paper

RSG Deployment Case Testing Results

2005-09-01

The RSG deployment case design is centered on taking the RSG system and producing a transport case that houses the RSG in a safe and controlled manner for transport. The transport case was driven by two conflicting constraints, first that the case be as light as possible, and second that it meet a stringent list of Military Specified requirements. The design team worked to extract every bit of weight from the design while striving to meet the rigorous Mil-Spec constraints. In the end compromises were made primarily on the specification side to control the overall weight of the transport case. This report outlines the case testing results.

The production of prompt isolated photons at hadron colliders provides a stringent test of perturbative QCD and can be used to probe the gluon density function of the proton. The ATLAS collaboration has performed precise measurements of the inclusive production o f isolated prompt photons at a center-of-mass energy of 13 TeV, differential in both rap idity and the photon transverse momentum. In addition, the integrated and differential c ross sections for isolated photon pair production 8 TeV have been measured. The results are compared with state-of-the-art theory predictions at NLO in QCD and with predictions of several MC generators.

Statistical model calculations relative to the reactions sup(40)Ca (e,e'p) sup(39)K and sup(40)Ca(e,e'P sub(o)) sup(39)K sup(gs), using a modified version of the program STAPRE are compared with experimental results obtained from coincidence experiments carried out at the Mainz microtron MAMI A. Preliminary results indicate that the statistical decay of a 1 sup(-) level in the sup(40)Ca compound nucleus, at an excitation energy + 20 MeV, to the ground state of the sup(39)K residual nucleus is only about 15% of the total decay, indicating that direct and/or semi-direct mechanisms contribute to the major part of the decay.

Purpose: Use of high density concrete for radiation shielding is increasing, trading cost for space savings associated with the reduced tenth value layer (TVL). Precise information on the attenuation properties of high-density concretes is not readily present in the literature. A simple approximation is to scale the TVLs from NCRP 151 according relative increase in density. Here we present measured TVLs for heavy concretes of various densities using a built-in shielding test port. Methods: Concrete densities tested range from 2.35 g cc{sup −1} (147 pcf) to 5.6 g cc{sup −1} (350 pcf). Measurements were taken using 6MV, 6FFF, and 10FFF on a Varian Truebeam linear accelerator. Field sizes of 4x4, 9x9 and 30x30 cm{sup 2} were measured. A PTW 31013 Farmer chamber with a buildup cap was positioned 5.5 m from isocenter along the beam CAX. Concrete thicknesses were incremented in 5 cm intervals. Comparison TVLs were determined by scaling the NCRP 151 TVLs by the density ratio between the sample and standard density. Results: The trend from the first to equilibrium TVL was an increase in thickness, compared with MC modeling, which predicted a decrease. Measured TVLs for 6 MV were reduced by as much as 8.9 cm for TVL{sub 1} and 3.4 cm for TVL{sub E} compared to values scaled from NCRP 151. There was 1–3 mm difference in TVL between measurements done at 4x4 versus 30x30 cm{sup 2}. TVL{sub 1} for 6FFF was 1.1 cm smaller than TVL{sub 1} for 6MV, but TVL{sub E} was consistent to within 4 mm. TVL{sub 1} and TVL{sub E} for 10FFF were reduced by 8.8 and 3.7 cm from scaled NCRP values, respectively. Conclusions: We have measured the TVL thicknesses for various concretes. Simple density scaling of the values in NCRP 151 is a conservatively safe approximation, but actual TVLs may be reduced enough to eliminate some of the expense of installation.

Purpose: Use of high density concrete for radiation shielding is increasing, trading cost for space savings associated with the reduced tenth value layer (TVL). Precise information on the attenuation properties of high-density concretes is not readily present in the literature. A simple approximation is to scale the TVLs from NCRP 151 according relative increase in density. Here we present measured TVLs for heavy concretes of various densities using a built-in shielding test port. Methods: Concrete densities tested range from 2.35 g cc −1 (147 pcf) to 5.6 g cc −1 (350 pcf). Measurements were taken using 6MV, 6FFF, and 10FFF on a Varian Truebeam linear accelerator. Field sizes of 4x4, 9x9 and 30x30 cm 2 were measured. A PTW 31013 Farmer chamber with a buildup cap was positioned 5.5 m from isocenter along the beam CAX. Concrete thicknesses were incremented in 5 cm intervals. Comparison TVLs were determined by scaling the NCRP 151 TVLs by the density ratio between the sample and standard density. Results: The trend from the first to equilibrium TVL was an increase in thickness, compared with MC modeling, which predicted a decrease. Measured TVLs for 6 MV were reduced by as much as 8.9 cm for TVL 1 and 3.4 cm for TVL E compared to values scaled from NCRP 151. There was 1–3 mm difference in TVL between measurements done at 4x4 versus 30x30 cm 2 . TVL 1 for 6FFF was 1.1 cm smaller than TVL 1 for 6MV, but TVL E was consistent to within 4 mm. TVL 1 and TVL E for 10FFF were reduced by 8.8 and 3.7 cm from scaled NCRP values, respectively. Conclusions: We have measured the TVL thicknesses for various concretes. Simple density scaling of the values in NCRP 151 is a conservatively safe approximation, but actual TVLs may be reduced enough to eliminate some of the expense of installation.

81 patients with renal anormalities or renal disorders of different genesis and severity with and without restricted renal functions were investigated by means of the classical PAH- and inulin-clearance. Furthermore a radioisotope nephrography was carried out after application of I 131-Hippuran followed by Cr 51-EDTA. In addition the activity reduction was measured above the shoulder, as well as the activity in serum samples and urine samples gained 30 min after application. A comparison of the clearance values found with those of conventional clearance resulted in poor correlation for I 131-Hippuran (r = 0.54) and no correlation for Cr 51-EDTA. Of the many parameters of the radioisotope nephrogram curves only the following are able to give sufficient quantitative functional results: The parameters connected with the rise of the curve between the 48sup(rh) and 120sup(rh) s and those connected with the slope of the secant. This is also true for the value of activity measured in the urine. (orig.) [de

New diffractive results from the Tevatron

Energy Technology Data Exchange (ETDEWEB)

Gallinaro, Michele; /Rockefeller U.

2005-05-01

Experimental results in diffractive processes are summarized and a few notable characteristics described in terms of Quantum Chromodynamics. Exclusive dijet production is used to establish a benchmark for future experiments in the quest for diffractive Higgs production at the Large Hadron Collider. Using new data from the Tevatron and dedicated diffractive triggers, no excess over a smooth falling distribution for exclusive dijet events could be found. Stringent upper limits on the exclusive dijet production cross section are presented. The quark/gluon composition of dijet final states is used to provide additional hints on exclusive dijet production.

QCD Results from ATLAS and CMS

Leyton, M; The ATLAS collaboration

2014-01-01

The ATLAS and CMS collaborations have performed a wide range of studies of QCD phenomena, from soft particle to hard photon and jet production. Recent soft-­QCD measurements include studies of the underlying event, double parton interactions and vector meson production. Differential measurements of inclusive and dijet production provide stringent tests of high­-order QCD predictions and provide input for the determination of parton density functions. Measurements of isolated, inclusive and di­-photon cross sections for high-pT photons test various theoretical predictions and further constrain PDFs. An overview of these results is given.


Assessing the value of Landsat imagery: Results from a 2012 comprehensive user survey

2012-12-01

Landsat satellite imagery has long been recognized as unique among remotely sensed data due to the combination of its extensive archive, global coverage, and relatively high spatial and temporal resolution. Since the imagery became available at no cost in 2008, the number of users registered with the U.S. Geological Survey (USGS) has increased tenfold while the number of scenes downloaded annually has increased a hundredfold. It is clear that the imagery is being used extensively, and understanding the benefits provided by this imagery can help inform decisions involving its provision. However, the value of Landsat imagery is difficult to measure for a variety of reasons, one of which stems from the fact that the imagery has characteristics of a public good and does not have a direct market price to reflect its value to society. Further, there is not a clear understanding of the full range of users of the imagery, as well as how these users are distributed across the many different end uses this data is applied to. To assess the value of Landsat imagery, we conducted a survey of users registered with USGS in early 2012. Over 11,000 current users of Landsat imagery responded to the survey. The value of the imagery was measured both qualitatively and quantitatively. To explore the qualitative value of the imagery, users were asked about the importance of the imagery to their work, their dependence on the imagery, and the impacts on their work if there was no Landsat imagery. The majority of users deemed Landsat imagery important to their work and stated they were dependent on Landsat imagery to do their work. Additionally, if Landsat imagery was no longer available, over half of the users would have to discontinue some of their work. On average, these users would discontinue half of their current work if the imagery was no longer available. The focus of this presentation will be the quantitative results of a double-bounded contingent valuation analysis which reveals

A method for preparation of copper nanoparticles (Cu-NPs) was developed by simple reduction of CuCl2 in the presence of gelatin as a stabilizer and without applying stringent conditions like purging with nitrogen. The NPs were characterized by spectrophotometry, dynamic light scattering, x-ray diffraction, transmission electron microscopy, atomic force microscopy and x-ray photoelectron spectroscopy. The particles were about 50-60 nm in size and highly stable. The antibacterial activity of this Cu-NP on Gram-negative Escherichia coli was demonstrated by the methods of agar plating, flow cytometry and phase contrast microscopy. The minimum inhibitory concentration (3.0 µg ml-1), minimum bactericidal concentration (7.5 µg ml-1) and susceptibility constant (0.92) showed that this Cu-NP is highly effective against E. coli at a much lower concentration than that reported previously. Treatment with Cu-NPs made E. coli cells filamentous. The higher the concentration of Cu-NPs, the greater the population of filamentous cells; average filament size varied from 7 to 20 µm compared to the normal cell size of ˜2.5 µm. Both filamentation and killing of cells by Cu-NPs (7.5 µg ml-1) also occurred in an E. coli strain resistant to multiple antibiotics. Moreover, an antibacterial effect of Cu-NPs was also observed in Gram-positive Bacillus subtilis and Staphylococcus aureus, for which the values of minimum inhibitory concentration and minimum bactericidal concentration were close to that for E. coli.

To reduce pediatric obesity in clinical settings, multidisciplinary behaviorally-based treatment programs are recommended. High attrition and poor compliance are two difficulties frequently encountered in such programs. A brief, empathic and directive clinical intervention, Motivational Interviewing (MI), might help address these motivational and behavioral issues, ultimately resulting in more positive health outcomes. The efficacy of MI as an adjunct in the treatment of pediatric obesity remains relatively understudied. MI Values was developed to implement within an existing multidisciplinary treatment program for obese, ethnically diverse adolescents, the T.E.E.N.S. Program (Teaching, Encouragement, Exercise, Nutrition, Support). T.E.E.N.S. participants who consent to MI Values are randomized to either MI or an education control condition. At weeks 1 and 10 of T.E.E.N.S. participation, the subset of participants assigned to the MI condition engages in individual MI sessions and control participants view health education videos. All MI sessions are audiotaped and coded to monitor treatment fidelity, which has been satisfactory thus far. Participants complete comprehensive assessments at baseline, 3- and 6-month follow-ups. We hypothesize that MI participants will demonstrate greater reductions in Body Mass Index (BMI) percentile, improved diet and physical activity behaviors, better compliance with T.E.E.N.S., and lower attrition than participants in the control group. We present study design and methods for MI Values as well as data on feasibility of recruitment methods and treatment integrity. At study completion, findings will contribute to the emerging literature examining the efficacy of MI in the treatment of pediatric obesity. Copyright © 2011 Elsevier Inc. All rights reserved.

Quantifying how smokers value attributes of electronic cigarettes.

Nonnemaker, James; Kim, Annice E; Lee, Youn Ok; MacMonegle, Anna

2016-04-01

Rates of electronic cigarette (e-cigarette) use have increased quickly among US adults (3.3% in 2010 to 8.5% in 2013) and youth (4.5% in 2013 to 13.4% in 2014). As state and local governments consider regulatory policies, understanding what smokers believe about e-cigarettes and how they value e-cigarettes is important. Using data from a convenience sample of Florida adult smokers (N=765), we investigated the value smokers place on specific attributes of e-cigarettes (availability of flavours, effectiveness of e-cigarettes as a cessation aid, healthier alternative to regular cigarettes, ability to use e-cigarettes in public places) by asking smokers how much they would be willing to pay for e-cigarettes with and without each of these attributes. For cigarette-only and dual users, losing the ability to use an e-cigarette as a quit aid and losing the harm reduction of an e-cigarette significantly reduced the price respondents were willing to pay for an e-cigarette. For cigarette-only users, not being able to use an e-cigarette indoors and losing flavours also significantly reduced the price respondents were willing to pay for an e-cigarette. Our results suggest that smokers value multiple attributes of e-cigarettes. Our valuation measures also appear to align with smokers' beliefs about e-cigarettes.

Utilizou-se um delineamento inteiramente ao acaso, com quatro forrageiras e cinco repetições. As forragens foram ensiladas em silos de PVC com 50 cm de altura e 10 cm de diâmetro, providos de válvula de Bunsen, que foram armazenados por 60 dias. As perdas por gases e por efluente foram avaliadas por diferença de peso antes e após a ensilagem. As perdas por gases foram relativamente pequenas em comparação às perdas por efluente. A silagem de milho se destacou por apresentar menores perdas, enquanto as de girassol e sorgo-sudão apresentaram maiores perdas por efluente. A silagem de sorgo-sudão possui menor valor nutritivo, em decorrência dos maiores teores das frações fibrosas, enquanto a de milho destaca-se positivamente pelo seu valor nutricional.The objective of this study was to assess the losses and nutritional value of silages of different forage crops (corn, Sudan sorghum, forage sorghum and sunflower ensiled at the ideal time for each crop. A randomized complete design was used, with four forage crops and five replications. The forages were ensiled in PVC silos, 50 cm high and 10 cm in diameter, equipped with a Bunsen valve, that were stored for 60 days. The losses through gases and effluent were assessed for difference in weight before and after ensilaging. The losses by gases were relatively small compared with the losses by effluent. The corn silage stood out because it presented smaller losses, while the sunflower and Sudan sorghum presented greater losses by effluent. The Sudan sorghum silage presents the lowest nutritional value, due to the greater contents of the fibrous fractions, while the corn silage stand out positively because of its nutritional value.

Introduction Given the rapid increase in e-cigarette use, it is important to understand factors that may contribute to their initiation and maintenance. Because gender differences in tobacco use, product preferences, and expectancies are well established, similar gender differences may exist with e-cigarettes. The aim of this study was to identify gender differences among e-cigarette users in patterns of use, reasons for initiation and maintenance, and outcome expectancies regarding e-cigarettes. Methods Participants (N = 1815) completed an online survey from August through November, 2013. We assessed sociodemographics, smoking and e-cigarette history and use, and expectancies about e-cigarettes. Results We found gender differences in type of e-cigarette used, flavors used, nicotine dosage, source of information about e-cigarettes, place of purchase, and use of e-cigarettes where smoking is prohibited. In addition, males were more likely to report initiating e-cigarette use to quit smoking due to health concerns, whereas females were more likely to report initiation based on recommendations from family and friends. Males reported higher attributions for maintenance of e-cigarette use related to positive reinforcement (enjoyment), whereas females reported higher negative reinforcement attributions (stress reduction or mood management). Males reported more positive expectancies about e-cigarettes, including taste, social facilitation, and energy, whereas women rated e-cigarettes higher for weight control. Males also reported greater addiction-related e-cigarette expectancy than females. Conclusions Many of the gender differences with e-cigarettes parallel those previously found with traditional cigarette smoking. Although effect sizes associated with these differences were small, the results may help advance research and intervention development with respect to e-cigarette initiation, maintenance and cessation.

The value of innovation under value-based pricing.

Science.gov (United States)

Moreno, Santiago G; Ray, Joshua A

2016-01-01

The role of cost-effectiveness analysis (CEA) in incentivizing innovation is controversial. Critics of CEA argue that its use for pricing purposes disregards the 'value of innovation' reflected in new drug development, whereas supporters of CEA highlight that the value of innovation is already accounted for. Our objective in this article is to outline the limitations of the conventional CEA approach, while proposing an alternative method of evaluation that captures the value of innovation more accurately. The adoption of a new drug benefits present and future patients (with cost implications) for as long as the drug is part of clinical practice. Incidence patients and off-patent prices are identified as two key missing features preventing the conventional CEA approach from capturing 1) benefit to future patients and 2) future savings from off-patent prices. The proposed CEA approach incorporates these two features to derive the total lifetime value of an innovative drug (i.e., the value of innovation). The conventional CEA approach tends to underestimate the value of innovative drugs by disregarding the benefit to future patients and savings from off-patent prices. As a result, innovative drugs are underpriced, only allowing manufacturers to capture approximately 15% of the total value of innovation during the patent protection period. In addition to including the incidence population and off-patent price, the alternative approach proposes pricing new drugs by first negotiating the share of value of innovation to be appropriated by the manufacturer (>15%?) and payer (price that satisfies this condition. We argue for a modification to the conventional CEA approach that integrates the total lifetime value of innovative drugs into CEA, by taking into account off-patent pricing and future patients. The proposed approach derives a price that allows manufacturers to capture an agreed share of this value, thereby incentivizing innovation, while supporting health

Recreation value of a waterway and changes in this value

International Nuclear Information System (INIS)

Aittoniemi, P.

1991-01-01

The uniquely rich hydrological and archipelagic nature of Finland creates versatile opportunities for spending of leisure time. As various uses of waterways compete with each other, it is difficult to compare advantages and disadvantages of operations in view of various interests. This is why efforts have been made to develop methods to make the effect commensurable. Usability of shores is one important factor in the assessment of recreation use of waterways. When influence of water level changes in usability of shores is estimated, shore and bottom slope and quality, and uses and user numbers of the shores must be known. In several assessment methods, usability of shore is depicted by distance of the shifted shoreline (due to the changed water level) from the 'good' status. The studies on changes in the recreation value or usability of shores should be started by making efforts to classify and estimate various effects separately. If the value is wished to be given as one figure, the calculation basis applied, the weights and the used value functions must be stated clearly with the results. It is equally important to make a sensitivity analysis, i.e. to study effects of changes in uncertain input data on the results

Cloud Computing Value Chains: Understanding Businesses and Value Creation in the Cloud

Mohammed, Ashraf Bany; Altmann, Jörn; Hwang, Junseok

Based on the promising developments in Cloud Computing technologies in recent years, commercial computing resource services (e.g. Amazon EC2) or software-as-a-service offerings (e.g. Salesforce. com) came into existence. However, the relatively weak business exploitation, participation, and adoption of other Cloud Computing services remain the main challenges. The vague value structures seem to be hindering business adoption and the creation of sustainable business models around its technology. Using an extensive analyze of existing Cloud business models, Cloud services, stakeholder relations, market configurations and value structures, this Chapter develops a reference model for value chains in the Cloud. Although this model is theoretically based on porter's value chain theory, the proposed Cloud value chain model is upgraded to fit the diversity of business service scenarios in the Cloud computing markets. Using this model, different service scenarios are explained. Our findings suggest new services, business opportunities, and policy practices for realizing more adoption and value creation paths in the Cloud.

Reduced transition strengths expressed with B(E2) values are good signatures to describe collective excitations of atomic nuclei and are indispensable to understand nuclear shell structures. Along the N=Z line in the pf shell they provide stringent tests of recent shell model interactions. So far, B(E2, 2{sub 1}{sup +} → 0{sub 1}{sup +}) values for the self-conjugate {sub 22}{sup 44}Ti, {sub 24}{sup 48}Cr, {sub 26}{sup 52}Fe isotopes are known only with considerable errors. Recoil Distance Doppler Shift (RDDS) experiments were performed employing the Cologne coincidence plunger device to measure lifetimes with high precision in order to deduce model-independent B(E2) values for the 2{sub 1}{sup +} → 0{sub 1}{sup +} transition. Excited states in the nuclei of interest were populated with fusion-evaporation reactions. γ rays were detected by an array of 12 HPGe detectors, positioned at favourable forward and backward angles with respect to the beam axis. First results on {sup 44}Ti, {sup 48}Cr and {sup 52}Fe are presented.

Qualitative Analysis of Chang'e-1 γ-ray Spectrometer Spectra Using Noise Adjusted Singular Value Decomposition Method

Yang Jia; Ge Liangquan; Xiong Shengqing

2010-01-01

From the features of spectra shape of Chang'e-1 γ-ray spectrometer(CE1-GRS) data, it is difficult to determine elemental compositions on the lunar surface. Aimed at this problem, this paper proposes using noise adjusted singular value decomposition (NASVD) method to extract orthogonal spectral components from CE1-GRS data. Then the peak signals in the spectra of lower-order layers corresponding to the observed spectrum of each lunar region are respectively analyzed. Elemental compositions of each lunar region can be determined based upon whether the energy corresponding to each peak signal equals to the energy corresponding to the characteristic gamma-ray line emissions of specific elements. The result shows that a number of elements such as U, Th, K, Fe, Ti, Si, O, Al, Mg, Ca and Na are qualitatively determined by this method. (authors)

e+-e- hadronic multiplicity distributions

Carruthers, P.; Shih, C.C.

1986-01-01

The 29 GeV multiplicity data have been analyzed for e + -e - → hadrons using the partially coherent laser distribution (PCLD). The latter interpolates between the negative binomial and Poisson distributions as the ratio S/N of coherent/incoherent multiplcity varies from zero to infinity. The negative binomial gives an excellent fit for rather large values of the cell parameter k. Equally good fits (for full and partial rapidity range, and for the forward/backward 2 jet correlation) are obtained for the mostly coherent (almost Poissonian) PCLD with small values of k (equal to the number of jets). The reasons for the existence of this tradeoff are explained in detail. The existence of the resulting ambiguity is traced to the insensitivity of the probability distribution to phase information in the hadronic density matrix. The study of higher order correlations (intensity interferometry) among like sign-particles is recommended to resolve this question

Full Text Available Introduction. Financial results of the banking institution activity are one of the most important indicators of its functioning. They characterize the stability and reliability of a commercial bank, which is necessary to create reserve funds, to encourage staff and offer guidance to develop and improve operations on the market, reduce costs and improve the quality of services provided. Purpose. The purpose of the study is to determine the composition and significance of financial results for the functioning of the banking institution in the existing competitive environment. Results. The article considers the concept of financial results of a commercial bank as an important element of its activity for achieving competitive advantages in the banking services market. The composition and structure of financial results, factors of possible impact on them are determined. The source of the mapping and recording of the results of the activity is indicated. Attention is paid to the significance of profit as a positive financial result of a commercial bank activity and the priority directions of its distribution are formed. The importance of the relative indicator of the effective activity of a commercial bank as one of the elements of the formation of financial results is substantiated. Conclusions. Thus, in today’s market conditions, one can talk about the expediency of determining the composition of financial results and their significance to ensure the main directions of the functioning of a commercial bank. First of all, in order to increase the level of profitability it is necessary to carry out a comprehensive analysis of income and expenditure, to identify the factors of influence on them, to increase the reserves of activity. Receiving a positive or negative value of financial performance depends primarily on the effectiveness of the interaction of each component of the organization of a modern commercial bank.

Hydraulic testing was conducted in three boreholes in southeastern Utah to provide a portion of the data needed to characterize the hydrogeology of the Elk Ridge and Gibson Dome areas of the western Paradox Basin, Utah. The tests at the E. J. Kubat borehole yielded representative values of transmissivity, hydraulic conductivity, storativity, and potentiometric levels of the Leadville Limestone. Testing at Elk Ridge No. 1 provided values of similar parameters for the combined thickness of the upper Honaker Trail, Elephant Canyon, and Cedar Mesa formations. Composite transmissivities of similar zones from these borehole tests compared closely with the results of testing at borehole GD-1. A comparison of results from lab tests on core with results of extensive borehole testing at GD-1 indicates that short-term drill stem tests in a single well can provide representative estimates of bulk transmissivities and hydraulic conductivities in this field area for test zones that have a hydraulic conductivity of greater than about 1 x 10 -7 cm/sec. However, lab tests produce more representative values of effective porosity and matrix permeability of individual strata. Results of lab tests and long-term borehole tests confirm that the lower Honaker Trail and upper Paradox formations have extremely low conductivities in the vicinity of the GD-1 borehole. The results of these tests were complete as of January 1981. 22 references, 29 figures, 5 tables

O EVA® é definido como a diferença entre o lucro operacional líquido depois de impostos e o custo do capital investido na empresa, enquanto o MVA® é determinado pela diferença entre o valor de mercado da empresa e o capital total nela investido. Um estudo realizado por G. Bennett Stewart III, que idealizou essas metodologias juntamente com o seu sócio Joel M. Stern, encontrou uma forte correlação entre o EVA® e o MVA®. Visando averiguar se tal resultado se aplica também ao caso das empresas brasileiras, os autores deste artigo realizaram uma pesquisa semelhante, baseada numa amostra formada por empresas de capital aberto cujas ações foram negociadas na Bovespa (Bolsa de Valores de São Paulo durante o período de 1996 a 2001.This article deals with value creation as measured by Economic Value Added (EVA® and Market Value (MVA® which are methods developed by an American consultant, Stern Stewart & Co, in the late l980's. Economic Value Added is defined as the difference between net operating profit after taxes and the cost of capital invested in a company, while Market Value Added is the difference between market value and the total capital invested in a company. G. Bennett Stewart III, who conceived this approach together with his partner Joel M. Stern, found a strong correlation between Economic Value Added and Market Value Added. Our research investigated whether this also applies to a sample of publicly owned Brazilian companies traded on the São Paulo Stock Exchange between 1996 and 2001.

Recent QCD results from ATLAS at the LHC

CERN Document Server

Keoshkerian, H; The ATLAS collaboration

2014-01-01

The ATLAS collaboration has performed studies of a wide range of QCD phenomena, from soft particle to hard photon and jet production. Recent soft-QCD measurements include studies of underlying event, vector meson production. Differential measurements of inclusive and dijet production provide stringent tests of high-order QCD predictions and provide input for determination of parton density functions. Measurements of isolated inclusive and di-photons cross sections for high p_T photons test various theoretical predictions and constrain parton density functions. An overview of these results is given.

Some recent results are presented from AGS E802, a survey experiment which is studying reactions of 14.6 A · GeV beams of protons, 16 O and 28 Si on targets ranging from 9 Be to 197 Au. Spectra for the global forward and transverse energy are shown; in nucleus-nucleus collisions these two quantities are anticorrelated, consistent with a large amount of stopping. Slope parameters from inclusive particle spectra are presented, with the most interesting effect being an apparent ''heating'' of mid-rapidity protons which emerge from the collisions of the largest nuclei. Also given are preliminary data on the production of antiprotons. 8 refs., 4 figs., 1 tab

Users, uses, and value of Landsat satellite imagery: results from the 2012 survey of users

Landsat satellites have been operating since 1972, providing a continuous global record of the Earth’s land surface. The imagery is currently available at no cost through the U.S. Geological Survey (USGS). Social scientists at the USGS Fort Collins Science Center conducted an extensive survey in early 2012 to explore who uses Landsat imagery, how they use the imagery, and what the value of the imagery is to them. The survey was sent to all users registered with USGS who had accessed Landsat imagery in the year prior to the survey and over 11,000 current Landsat imagery users responded. The results of the survey revealed that respondents from many sectors use Landsat imagery in myriad project locations and scales, as well as application areas. The value of Landsat imagery to these users was demonstrated by the high importance of and dependence on the imagery, the numerous environmental and societal benefits observed from projects using Landsat imagery, the potential negative impacts on users’ work if Landsat imagery was no longer available, and the substantial aggregated annual economic benefit from the imagery. These results represent only the value of Landsat to users registered with USGS; further research would help to determine what the value of the imagery is to a greater segment of the population, such as downstream users of the imagery and imagery-derived products.

To study clinical significance of combined detection of leptin, T and E 2 for teenager obesity patients, levels of leptin, T and E 2 in male teenagers obesity patients and male adult obesity patients were determined by RIA. The result showed that in all obesity patients, the levels of leptin and E 2 were much higher than those in normal controls and T was lower than that in normal controls. After treatment, leptin and E 2 were decreased and T was increased significantly in teenager obesity patients, but only leptin was decreased in adult obesity patients. All results indicate that combined detection of leptin, T and E 2 could find endocrine and metabolism disorder of obese teenagers at early stage, instituting prevention and treatment without delay.(authors)

The K_L -> pi+pi-e+e- and K_S -> pi+pi-e+e- decay modes have been studied in detail using the NA48 detector at CERN SPS. Based on the data collected during the 1998 and 1999 run periods, a sample of 1162 K_L -> pi+pi-e+e- candidates has been observed with an expected background level of 36.9 events, yielding the branching ratio measurement BR(K_L -> pi+pi-e+e-)=(3.08+-0.20)x10^-7. The distribution of events in the sin\\phicos\\phi variable, where \\phi is the angle between the pi+pi- and the e+e- decay planes in the kaon centre of mass, is found to exhibit a large CP-violating asymmetry with the value A_\\phi(14.2+-3.6)%. For the K_S -> pi+pi-e+e- decay channel, 621 candidates have been identified in the 1999 data sample with an estimated background contribution of 0.7 event.

1978-01-01

The results of zero power physics testing measurements in LOFT have been evaluated to assess the adequacy of the physics data used in the safety analyses performed for the LOFT FSAR and Technical Specifications. Comparisons of measured data with computed data were made for control rod worths, temperature coefficients, boron worths, and pressure coefficients. Measured boron concentrations at exact critical points were compared with predicted concentrations. Based on these comparisons, the reactivity parameter values used in the LOFT safety analyses were assessed for conservatism

This thesis presents the DELPHI measurement of event shape distributions and inclusive spectra in e+e- annihilation at LEP between 183 and 207 GeV. These data have been reprocessed in 2001 and the results supersede some older DELPHI measurements at the corresponding energies [1, 2, 3, 4, 5]. The differential distributions in Ep = ln 1/xp and their maxima E* are compared with predictions in the MLLA/LPHD framework. These tests support the manifestation of coherence effects on the hadronic level. From the event shapes Thrust, C parameter heavy jet mass wide and total jet broadening s is extracted with four different methods: The differential distributions are compared to predictions in O s pure NLLA and O s + NLLA logR folded with fragmentation models For the mean values s is extracted using an analytical power correction ansatz. The s values are combined with results obtained at other LEP energies and at and around MZ This allows both a combined measurement of s and a test of the running of s The smallest unce...

Thermodynamic properties of indan: Experimental and computational results

Chirico, Robert D.; Steele, William V.; Kazakov, Andrei F.

2016-01-01

Highlights: • Heat capacities were measured for the temperature range (5 to 445) K. • Vapor pressures were measured for the temperature range (338 to 495) K. • Densities at saturation pressure were measured from T = (323 to 523) K. • Computed and experimentally derived properties for ideal gas entropies are in excellent accord. • Thermodynamic consistency analysis revealed anomalous literature data. - Abstract: Measurements leading to the calculation of thermodynamic properties in the ideal-gas state for indan (Chemical Abstracts registry number [496-11-7], 2,3-dihydro-1H-indene) are reported. Experimental methods were adiabatic heat-capacity calorimetry, differential scanning calorimetry, comparative ebulliometry, and vibrating-tube densitometry. Molar thermodynamic functions (enthalpies, entropies, and Gibbs energies) for the condensed and ideal-gas states were derived from the experimental studies at selected temperatures. Statistical calculations were performed based on molecular geometry optimization and vibrational frequencies calculated at the B3LYP/6-31+G(d, p) level of theory. Computed ideal-gas properties derived with the rigid-rotor harmonic-oscillator approximation are shown to be in excellent accord with ideal-gas entropies derived from thermophysical property measurements of this research, as well as with experimental heat capacities for the ideal-gas state reported in the literature. Literature spectroscopic studies and ab initio calculations report a range of values for the barrier to ring puckering. Results of the present work are consistent with a large barrier that allows use of the rigid-rotor harmonic-oscillator approximation for ideal-gas entropy and heat-capacity calculations, even with the stringent uncertainty requirements imposed by the calorimetric and physical property measurements reported here. All experimental results are compared with property values reported in the literature.

The correction of the littlest Higgs model to the Higgs production process e+e-→e+e-H at the ILC

Wang, Xuelei; Liu, Yaobei; Chen, Jihong; Yang, Hua

2007-01-01

The littlest Higgs model is the most economical one among various little Higgs models. In the context of the littlest Higgs model, we study the process e + e - →e + e - H at the ILC and calculate the correction of the littlest Higgs model to the cross section of this process. The results show that, in the favorable parameter spaces preferred by the electroweak precision data, the value of the relative correction is in the range from a few percent to tens percent. In most cases, the correction is large enough to reach the measurement precision of the ILC. Therefore, the correction of the littlest Higgs model to the process e + e - →e + e - H might be detected at the ILC, which will give an ideal way to test the model. (orig.)

2012-01-01

This book is the second enlarged and revised edition of the first successful monograph on complex-valued neural networks (CVNNs) published in 2006, which lends itself to graduate and undergraduate courses in electrical engineering, informatics, control engineering, mechanics, robotics, bioengineering, and other relevant fields. In the second edition the recent trends in CVNNs research are included, resulting in e.g. almost a doubled number of references. The parametron invented in 1954 is also referred to with discussion on analogy and disparity. Also various additional arguments on the advantages of the complex-valued neural networks enhancing the difference to real-valued neural networks are given in various sections. The book is useful for those beginning their studies, for instance, in adaptive signal processing for highly functional sensing and imaging, control in unknown and changing environment, robotics inspired by human neural systems, and brain-like information processing, as well as interdisciplina...

Value is in the eye of the beholder: early visual cortex codes monetary value of objects during a diverted attention task.

Persichetti, Andrew S; Aguirre, Geoffrey K; Thompson-Schill, Sharon L

2015-05-01

A central concern in the study of learning and decision-making is the identification of neural signals associated with the values of choice alternatives. An important factor in understanding the neural correlates of value is the representation of the object itself, separate from the act of choosing. Is it the case that the representation of an object within visual areas will change if it is associated with a particular value? We used fMRI adaptation to measure the neural similarity of a set of novel objects before and after participants learned to associate monetary values with the objects. We used a range of both positive and negative values to allow us to distinguish effects of behavioral salience (i.e., large vs. small values) from effects of valence (i.e., positive vs. negative values). During the scanning session, participants made a perceptual judgment unrelated to value. Crucially, the similarity of the visual features of any pair of objects did not predict the similarity of their value, so we could distinguish adaptation effects due to each dimension of similarity. Within early visual areas, we found that value similarity modulated the neural response to the objects after training. These results show that an abstract dimension, in this case, monetary value, modulates neural response to an object in visual areas of the brain even when attention is diverted.

Politicians, philosophers, and rhetors engage in co-value argumentation: appealing to one value in order to support another value (e.g., “equality leads to freedom”). Across four experiments in the United Kingdom and India, we found that the psychological relatedness of values affects the persuasiveness of the arguments that bind them. Experiment 1 found that participants were more persuaded by arguments citing values that fulfilled similar motives than by arguments citing opposing values. Experiments 2 and 3 replicated this result using a wider variety of values, while finding that the effect is stronger among people higher in need for cognition and that the effect is mediated by the greater plausibility of co-value arguments that link motivationally compatible values. Experiment 4 extended the effect to real-world arguments taken from political propaganda and replicated the mediating effect of argument plausibility. The findings highlight the importance of value relatedness in argument persuasiveness. PMID:25147529

This programme is offered at the College of Polytechnics Jihlava and covers two fields of study - Travel and Tourism, Finance and Management. The comparison is aimed at the results of the period before the start of the e-learning (2008 for full time students and 2010 for combined form with the year 2012 (after the e-learning implementation. The results from eight biggest subjects are tested via Chi-square test of independence. It should answer the question if the e-learning has had an impact on the study results and if it is possible to find dependence between results of two different types of study, two different years, two different study branches and two different subjects. The comparison has shown the differences of combined/full time students but we have not proved the influence of the e-learning on the evaluation.

B(E2;0+1→2+1) values for the unstable, neutron-rich nuclei 132,134Te were determined through Coulomb excitation, in inverse kinematics, of accelerated beams of these nuclei. The systematics of measured B(E2) values from the ground state to the first excited state have been extended to the N=82 shell closure in the Te nuclei and have been compared with the predictions of different theories. The measurements were performed at the Holifield Radioactive Ion Beam Facility (HRIBF) using the GRAFIK detector. The success of this approach, which couples a 5.7% efficient through-well NaI(Tl) γ-ray detector with thin foil microchannel plate beam detectors, also demonstrates the feasibility for Coulomb excitation studies of neutron-rich nuclei even further from the valley of beta stability, both at present-generation ISOL facilities and at the proposed Rare Isotope Accelerator.

Reduced transition strengths expressed with B(E2) values are sensitive signatures to describe collective excitations of atomic nuclei and are indispensable to understand nuclear shell structures. Along the N=Z line in the 1f{sub 7/2} shell they provide stringent tests of recent shell-model interactions. So far, B(E2, 2{sub 1}{sup +} → 0{sub g.s.}{sup +}) values for the self-conjugate {sup 44}{sub 22}Ti,{sup 48}{sub 24}Cr,{sup 52}{sub 26}Fe isotopes are known only with considerable errors. Recoil Distance Doppler-Shift (RDDS) experiments were performed employing the Cologne coincidence plunger device to measure lifetimes with high precision in order to deduce model-independent B(E2) values. Excited states in the nuclei of interest were populated with fusion-evaporation reactions. γ rays were detected by an array of 12 HPGe detectors. Precise B(E2, 2{sub 1}{sup +} → 0{sub g.s.}{sup +}) values are measured to be 204{sup +16}{sub -14} e{sup 2}fm{sup 4}, 262 ± 3 e{sup 2}fm{sup 4}, and 269 ± 8 e{sup 2}fm{sup 4} for {sup 44}Ti, {sup 48}Cr, and {sup 52}Fe, respectively. The results are compared to recent shell-model calculations on the basis of GX1A interaction. While the excitation energies are reproduced quite well, the B(E2) values show considerable differences.

A method for preparation of copper nanoparticles (Cu-NPs) was developed by simple reduction of CuCl 2 in the presence of gelatin as a stabilizer and without applying stringent conditions like purging with nitrogen. The NPs were characterized by spectrophotometry, dynamic light scattering, x-ray diffraction, transmission electron microscopy, atomic force microscopy and x-ray photoelectron spectroscopy. The particles were about 50–60 nm in size and highly stable. The antibacterial activity of this Cu-NP on Gram-negative Escherichia coli was demonstrated by the methods of agar plating, flow cytometry and phase contrast microscopy. The minimum inhibitory concentration (3.0 µg ml −1 ), minimum bactericidal concentration (7.5 µg ml −1 ) and susceptibility constant (0.92) showed that this Cu-NP is highly effective against E. coli at a much lower concentration than that reported previously. Treatment with Cu-NPs made E. coli cells filamentous. The higher the concentration of Cu-NPs, the greater the population of filamentous cells; average filament size varied from 7 to 20 µm compared to the normal cell size of ∼2.5 µm. Both filamentation and killing of cells by Cu-NPs (7.5 µg ml −1 ) also occurred in an E. coli strain resistant to multiple antibiotics. Moreover, an antibacterial effect of Cu-NPs was also observed in Gram-positive Bacillus subtilis and Staphylococcus aureus, for which the values of minimum inhibitory concentration and minimum bactericidal concentration were close to that for E. coli.

In this contribution the path independent J-integral according to J.R. Rice, respective J.D. Landes and J.A. Begley due to ASTME 813 is calculated by the product J pl = d v J el for 3 point bend type specimen. Here d v is the load point displacement up to the point of the onset of stable crack growth V, which is taken from the load versus load point displacement diagram and J el a value which is equivalent to K 2 /E, where K is the stress intensity factor (ASTME 399) and E is Young's modulus. The advantage of the new procedure is the simplicity of the test arrangement and of the evaluation with the determination of initiation point V without computer or other auxiliary equipment. (orig.)

Long-term risks of metal contaminants in drinking water: a critical appraisal of guideline values for arsenic and vanadium

Directory of Open Access Journals (Sweden)

Riccardo Crebelli

2012-12-01

Full Text Available Metal contaminants in drinking water represent a relevant health issue in several areas of the world. In Italy, because of the geological features of the territory, high arsenic and vanadium are frequently reported in ground waters in concentrations above current guideline values. The implications for public health of the presence of contaminants above their legal limit are directly related to the biological basis of the guideline value. In the case of arsenic there are still major uncertainties in the mechanism of carcinogenesis which prevent a precise evaluation of long-term risks. Thus, the guideline value endorsed in the European Community (10 µg/L has to be considered as a pragmatic tool rather than a quality objective, bearing in mind that "every effort should be made to keep concentrations as low as reasonably possible" (WHO, 2011. A reverse situation holds for vanadium, for which a strict national limit (50 µg/L was previously proposed in consideration of data gaps, and for which new evidence indicated a less stringent health-based limit.

2001-01-01

The 40 Ca(e,e'x; x=p,α) reaction has been measured in the giant resonance excitation region for E x ≅8-26 MeV. The present article is the first out of three describing the experiments and giving an overview of the results. Data were taken at four momentum transfers in the range q=0.26-0.66 fm -1 . Angular correlations for decay to the ground state and low-lying states of 39 K and 36 Ar could be extracted as a function of excitation energy in 40 Ca. Excitation energy spectra integrated over the particle emission angle were generated for the various resolved decay channels. Comparisons of the giant resonance cross-section distributions with results using other electromagnetic or hadronic probes have been made and good agreement is found in most cases

The skeletal trauma resulting from a fatal B.A.S.E jump: A case study showing the impact of landing feet-first under extreme vertical deceleration.

The term 'B.A.S.E jump' refers to jumping from a building, antenna, span (i.e., bridge) or earth (i.e., cliff) structure, and parachuting to the ground. There are numerous hazards associated with B.A.S.E jumps which often result in injury and, occasionally, fatality. This case report details the skeletal trauma resulting from a fatal B.A.S.E jump in Australia. In this case, the jumper impacted the ground from a fall of 439m in a feet-first landing position, as a result of a partially deployed parachute, under extreme vertical deceleration. Skeletal trauma was analyzed using full-body post mortem computed tomography (PMCT) and contextual information related to the circumstances of the jump as reported by the Coroner. Trauma to 61 skeletal elements indicates the primary impact was to the feet (i.e., feet-first landing), followed by an anterior impact to the body (i.e., fall forwards). Details of the individual fracture morphologies indicate the various forces and biomechanics involved in this fall event. This case presents the types of fractures that result from a B.A.S.E jump, and highlights the value of using PMCT and coronial data as tools to augment skeletal trauma interpretations.

Understanding what shape values (which ultimately shape human behavior) will help improve the effectiveness of conservation solutions that depend on public support. To contribute to this understanding, we investigated the influence of societal-level changes, such as modernization, on values in a multilevel framework. We collected survey responses (n = 4183) to questionnaires mailed to a random selection of households within each county in Washington (U.S.A.) (response rate 32%). We used multilevel modeling to determine the relationship between modernization (e.g., county-level urbanization, wealth, and education) and wildlife value orientations (values that shape thought about wildlife) while controlling for individual-level sociodemographics. We then explored how values influence conservation support at different levels (e.g., individual and county) and how values explain conservation support in a case study of public responses to wolf (Canis lupis) recovery. We found positive associations between county-level examples of modernization and mutualism (a wildlife value orientation that prioritizes the perceived needs of wildlife) independent of a respondent's sociodemographics, and negative associations between modernization and domination (a wildlife value orientation that prioritizes human needs). Our results suggest that context has an additive impact on one's values; certain locations exhibited domination values, whereas others exhibited a mix of value types. This finding is important because actions that restrict human interests to promote biodiversity were negatively associated with domination and positively associated with mutualism. In the wolf case study, mutualism was strongly correlated with less social conflict over wolf recovery in many, but not all, counties (e.g., Pearson's r correlation = 0.59 in one county and a nonsignificant correlation in another). Our findings suggest that modernization operates on values within a state with implications for

the opinion regarding DTCA, 69.9% physicians had a patient discussing DTCA that was clinically inappropriate. One hundred (64.5%) out of 155 physicians opined that DTCA encourage patients to attend physicians regarding preventive healthcare. On the contrary, 82/155 (52.9%) physicians felt that DTCA would damage the same. Similarly, 69 out of the total 100 patients felt that drug advertisements aid them to have better discussions with their treating physicians. Surprisingly, a large majority (91/100) were of the opinion that only safe drugs are allowed to be advertised. To conclude, from the findings of this study both the physicians and patients should be cautious and not overzealous while dealing with drug advertisements or promotional literature. More stringent scrutiny and issue of WLs or blacklisting of indulging pharmaceutical companies are mandatory by the regulatory agency to contain the same.

However, while the observed temporal increases in vitamin concentrations were likely POP related, the question remains as to whether they stem from influence of contaminants only or also, e.g., changes in prey species. Further studies are needed...... between POPs and vitamin concentrations. In addition, vitamin concentrations were analyzed for temporal trends (1994–2008). Results showed vitamin A in liver to be higher in adult bears and the concentrations of vitamin E in kidney and blood to likewise be generally higher in adult bears. In addition, all...

Employee-Organization Pro-environmental Values Fit and Pro-environmental Behavior: The Role of Supervisors' Personal Values.

Science.gov (United States)

Lu, Hui; Liu, Xia; Chen, Hong; Long, Ruyin

2017-12-18

This study examines the relationship among the employees-organization pro-environmental values fit (E-O PEVs fit), supervisors' PEVs and employees' pro-environmental behaviors (PEB). Informed by the PEB, organizational values and employee-organization fit literature, we propose and test hypotheses that under egoistic, altruistic and biosphere-value orientations, E-O PEVs fit versus non-fit have significant effects on employees' private-sphere PEB and public-sphere PEB, identifying supervisors' PEVs as a moderator. An empirical investigation indicates that the effect of E-O PEVs fit on employees' private-sphere PEB and public-sphere PEB varies as the value orientation differs. More specifically, under the context of altruistic and biosphere-value orientations, if the organizational PEVs do not match the employees' PEVs, especially when the former exceeds the latter, employees' PEB will rise as the organizational PEVs increase. As for egoistic value orientation, when organizational PEVs exceed employees' PEVs, not only will public-sphere PEB stop decreasing and tend to stabilize, but also private-sphere PEB will rise to a slight degree. Furthermore, compared with altruistic and biospheric values dimensions, supervisors who promote egoistic PEVs will have a more significant effect on the relationship between global E-O PEVs fit and employees' PEB. Finally, we suggest that the goals of an organization and its supervisors need to be combined within the actual situation of Chinese corporations to truly implement corporate green practices by balancing the profit goal and the environmental goal.

Steganography based on pixel intensity value decomposition

Science.gov (United States)

Abdulla, Alan Anwar; Sellahewa, Harin; Jassim, Sabah A.

2014-05-01

This paper focuses on steganography based on pixel intensity value decomposition. A number of existing schemes such as binary, Fibonacci, Prime, Natural, Lucas, and Catalan-Fibonacci (CF) are evaluated in terms of payload capacity and stego quality. A new technique based on a specific representation is proposed to decompose pixel intensity values into 16 (virtual) bit-planes suitable for embedding purposes. The proposed decomposition has a desirable property whereby the sum of all bit-planes does not exceed the maximum pixel intensity value, i.e. 255. Experimental results demonstrate that the proposed technique offers an effective compromise between payload capacity and stego quality of existing embedding techniques based on pixel intensity value decomposition. Its capacity is equal to that of binary and Lucas, while it offers a higher capacity than Fibonacci, Prime, Natural, and CF when the secret bits are embedded in 1st Least Significant Bit (LSB). When the secret bits are embedded in higher bit-planes, i.e., 2nd LSB to 8th Most Significant Bit (MSB), the proposed scheme has more capacity than Natural numbers based embedding. However, from the 6th bit-plane onwards, the proposed scheme offers better stego quality. In general, the proposed decomposition scheme has less effect in terms of quality on pixel value when compared to most existing pixel intensity value decomposition techniques when embedding messages in higher bit-planes.

Value analysis for advanced technology products

Science.gov (United States)

Soulliere, Mark

2011-03-01

Technology by itself can be wondrous, but buyers of technology factor in the price they have to pay along with performance in their decisions. As a result, the ``best'' technology may not always win in the marketplace when ``good enough'' can be had at a lower price. Technology vendors often set pricing by ``cost plus margin,'' or by competitors' offerings. What if the product is new (or has yet to be invented)? Value pricing is a methodology to price products based on the value generated (e.g. money saved) by using one product vs. the next best technical alternative. Value analysis can often clarify what product attributes generate the most value. It can also assist in identifying market forces outside of the control of the technology vendor that also influence pricing. These principles are illustrated with examples.

Small and medium sized wine producers dealing with business to business e-commerce: Towards a relational model for enhancing value (co- creation

Directory of Open Access Journals (Sweden)

Saba Andrea

2017-01-01

Full Text Available The internet has produced a forward-looking shift in the way we communicate, think and run economic activities around the globe. The revolution in Information and Communication Technology (ICT has generated an innovating process in the agri-food sector that is far from being unwind. The wine industry is a case in point. Indeed, the industry has attempted to address the multifaceted challenges posed by electronic commerce since always. Business to business electronic commerce has been slower to develop than its counterpart, i.e. business to consumer E-commerce. However business to business e-commerce is starting to attract an increased interest, by showing a significant business value in terms of potential. Against this background, the slow development of B2B e-commerce has been linked to regulatory and economic reasons. In order to deal with such stumbling blocks, the paper suggests a shift towards an open platform that is aimed at facilitating transactions and interactions among businesses through a continuous problem-solving process in which trust and value is co-created by producers and customers through relational contracting.

The paper presents the main examination results on the condition of fuel rods claddings, guide tubes and spacer grids of the WWER FA made of E110 and E635 alloys operated under standard operating conditions. The paper is based on the data obtained during the examination of 28 WWER-1000 FA and 12 WWER-400 FA. E110 alloy is shown to be suitable material for the WWER fuel rod claddings under the normal operating conditions. E635 alloy is attractive to manufacturing of the skeleton components. The currently used combination (E110 as a material of fuel rods claddings and E635 - as a material of the skeleton components) is the optimal solution for the WWER fuel assembly because the advantages of the both alloys are used.

Discrepancy between Clambda and Csub(E)

International Nuclear Information System (INIS)

Williams, P.C.

1977-01-01

The conversion factors Clambda and Csub(E) are used in relating ionization chamber readings (M) to absorbed dose in water for measurements made in phantoms irradiated with photons of quality lambda and electrons of mean energy - E respectively. New calculations of Clambda (Nahum, A.E., and Greening, J.R., 1976, Phys. Med. Biol., vol.21, 862) have yielded values which differ by up to 5% from those quoted by ICRU (ICRU, 1969, Report 14, ICRU Publications, P.O. Box 30165, Washington, DC 20014). Nahum and Greening have also pointed out that the recommended values of Clambda and Csub(E) for radiations of approximately the same primary electron energy should be the same, but differ by approximately 4%. Alternative explanations are offered for these discrepancies. If the ICRU values are corrected for the perturbation of the electron flux in the phantom by the introduction of a cavity, the ionization chamber, into the phantom, then the resulting values are in good agreement with those quoted by Nahum and Greening. The discrepancy between Clambda and Csub(E) is the result of inconsistent definitions. The ICRU definition of Csub(E) leads to a dose conversion factor which is dimensionally correct but is based on the assumption that the product M.Nsub(c), where Nsub(c) is the exposure calibration factor for the ionization chamber at the calibration quality, 2MV, can be identified as exposure, whereas this is only true at the calibration quality. More accurate definitions of Clambda and Csub(E) are therefore proposed. (U.K.)

This work presents the experimental values of H{sub m}{sup E}andV{sub m}{sup E} obtained at a temperature of 318.15 K and atmospheric pressure for a group of 24 binary mixtures comprised of the first four alkyl butanoates (methyl to butyl) with six odd alkanes, from heptane to heptadecane. All the mixtures are endothermic, and present a regular increase in H{sub m}{sup E} with the molecular weight of the saturated hydrocarbon, while, for a same alkane, the enthalpic effects diminish with increasing alcoholic chain of the butanoate. The variation in V{sub m}{sup E} occurs in the same direction. In this paper the structural behaviour of these systems and the influence of temperature on excess properties are analysed. Experimental data are correlated with a suitable polynomial equation which is given as a function of concentration and temperature, that permits a simultaneous correlation to be established with other properties of the mixture, such as (vapour + liquid) equilibria; and acceptable results are obtained. Finally, an estimation of H{sub m}{sup E} is made with two known versions of the UNIFAC model. In the version by Dang and Tassios [J. Dang, D.P. Tassios, Ind. Eng. Chem. Process Des. Dev. 25 (1986) 22-31.], a method is proposed that considers the interaction parameters as a function of the butanoate alkanolic chain. The estimations obtained for H{sub m}{sup E} are good.

Handling missing Mini-Mental State Examination (MMSE) values: Results from a cross-sectional long-term-care study.

Godin, Judith; Keefe, Janice; Andrew, Melissa K

2017-04-01

Missing values are commonly encountered on the Mini Mental State Examination (MMSE), particularly when administered to frail older people. This presents challenges for MMSE scoring in research settings. We sought to describe missingness in MMSEs administered in long-term-care facilities (LTCF) and to compare and contrast approaches to dealing with missing items. As part of the Care and Construction project in Nova Scotia, Canada, LTCF residents completed an MMSE. Different methods of dealing with missing values (e.g., use of raw scores, raw scores/number of items attempted, scale-level multiple imputation [MI], and blended approaches) are compared to item-level MI. The MMSE was administered to 320 residents living in 23 LTCF. The sample was predominately female (73%), and 38% of participants were aged >85 years. At least one item was missing from 122 (38.2%) of the MMSEs. Data were not Missing Completely at Random (MCAR), χ 2 (1110) = 1,351, p < 0.001. Using raw scores for those missing <6 items in combination with scale-level MI resulted in the regression coefficients and standard errors closest to item-level MI. Patterns of missing items often suggest systematic problems, such as trouble with manual dexterity, literacy, or visual impairment. While these observations may be relatively easy to take into account in clinical settings, non-random missingness presents challenges for research and must be considered in statistical analyses. We present suggestions for dealing with missing MMSE data based on the extent of missingness and the goal of analyses. Copyright © 2016 The Authors. Production and hosting by Elsevier B.V.

It is shown that a very satisfactory estimate of the energy values (for all values of the anharmonicity) and moments of the ground state of the quartic anharmonic oscillator can be obtained in the variational method, by considering trial wavefunctions which have the correct asymptotic properties. The results derived with a single variational parameter are a considerable improvement over the recent results of C.A. Ginsburg and E.W. Montroll (1978). (author)

Full Text Available Este trabalho foi realizado com o objetivo de avaliar o valor nutritivo de perfilhos e componentes morfológicos em pastos diferidos e adubados com nitrogênio de Brachiaria decumbens cv. Basilisk. Dois experimentos foram realizados em delineamento de blocos casualizados com três repetições e esquema de parcela subdivida. No primeiro experimento, foram realizadas combinações entre doses de nitrogênio (0, 40, 80 e 120 kg/ha com os componentes morfológicos (folha verde, colmo verde, folha morta e colmo morto ou com as categorias de perfilhos (vegetativo e reprodutivo do pasto. No segundo experimento, estudaram-se as combinações entre períodos de diferimento (73, 95 e 116 dias com categorias de perfilhos (vegetativo e reprodutivo. A adubação nitrogenada aumentou o percentual de fibra em detergente neutro (FDN nos colmos verdes e o teor de proteína bruta (PB nas folhas verdes e mortas e no colmo verde. Elevou também os percentuais de PB nos perfilhos vegetativos e reprodutivos, assim como o teor de FDN do perfilhos vegetativos. Maior período de diferimento causou acréscimo no percentual de FDN e redução no percentual de proteína bruta nos perfilhos vegetativos e reprodutivos. A dose de nitrogênio e o período de diferimento alteram o valor nutritivo dos componentes morfológicos e dos perfilhos dos pastos de B. decumbens cv. Basilisk.

Full Text Available Trata o presente artigo de uma investigação, no sentido de análise, do conceito do Fair Value (Valor Justo, tão debatido nos anos mais recentes e que promete ser, se generalizada sua aplicação nas demonstrações contábeis, uma verdadeira revolução valorativa. No decorrer do trabalho são analisadas, resumidamente, no que se refere aos aspectos mais importantes, as disposições e conceituações sobre Valor Justo apresentadas pelo IASB (International Accounting Standards Board, pelo FASB (Financial Accounting Standards Board e pelas Normas Brasileiras. A análise efetuada tem um caráter inicialmente semântico, no sentido de expressar, da forma mais clara possível, o sentido das palavras contidas nas conceituações. Em seguida, é feita uma análise qualitativa, visando extrair e avaliar o efetivo impacto das conceituações no avanço das práticas contábeis. Inicialmente, é importante ressaltar que a conceituação de Valor Justo é bastante antiga. Em 1939, Kenneth MacNeal, em seu pioneiro trabalho, Truth in Accounting, já definia a expressão, de forma brilhante; na verdade, falava em fair and true, atribuindo às valorações, sempre, um significado econômico. A discussão sobre Valor Justo acentuou-se sobremaneira, ganhando até contornos sensacionalistas, a partir do SFAS 133, emitido pelo FASB em 1998. Através da análise e investigação assim procedidas, é avaliada, por comparação, a eficácia e "justeza" do conceito, ou melhor, conceitos, de Valor Justo em face dos critérios de Custo Histórico, Custo Corrente de Reposição e outros, já praticados há mais tempo pelos contadores. Sugere-se, ao final, um período de experimentação com informações complementares ao modelo tradicional, e não a pura e simples substituição deste último, permitindo então à Contabilidade Positiva o papel de, mediante suas pesquisas empíricas, avaliar a relação entre a utilidade e o custo dessas alternativas antes de

ANTARES uses sea water as as a detection medium to observe cosmic neutrinos. The ANTARES neutrino telescope is taking data with its complete configuration since 2008. Its main goal is the detection of cosmic neutrinos from the Southern hemisphere sky, coming from Galactic and extragalactic sources. Recently, the ANTARES collaboration has published many results from data collected from 2007 to 2010 using detector configurations containing between 5 to 12 detection strings. Among those, search of point sources and diffuse flux from high energy cosmic neutrinos, both resulted in stringent and competitive upper limits for the flux of cosmic neutrinos. In addition, ANTARES is involved in multi-messenger projects looking for correlations between neutrinos and gamma rays or gravitational wave emitted by sources like Gamma-Ray bursts. In this paper we report on some recent results published by the ANTARES collaboration

Given the rapid increase in e-cigarette use, it is important to understand factors that may contribute to their initiation and maintenance. Because gender differences in tobacco use, product preferences, and expectancies are well established, similar gender differences may exist with e-cigarettes. The aim of this study was to identify gender differences among e-cigarette users in patterns of use, reasons for initiation and maintenance, and outcome expectancies regarding e-cigarettes. Participants (N=1815) completed an online survey from August through November, 2013. We assessed sociodemographics, smoking and e-cigarette history and use, and expectancies about e-cigarettes. We found gender differences in type of e-cigarette used, flavors used, nicotine dosage, source of information about e-cigarettes, place of purchase, and use of e-cigarettes where smoking is prohibited. In addition, males were more likely to report initiating e-cigarette use to quit smoking due to health concerns, whereas females were more likely to report initiation based on recommendations from family and friends. Males reported higher attributions for maintenance of e-cigarette use related to positive reinforcement (enjoyment), whereas females reported higher negative reinforcement attributions (stress reduction or mood management). Males reported more positive expectancies about e-cigarettes, including taste, social facilitation, and energy, whereas women rated e-cigarettes higher for weight control. Males also reported greater addiction-related e-cigarette expectancy than females. Many of the gender differences with e-cigarettes parallel those previously found with traditional cigarette smoking. Although effect sizes associated with these differences were small, the results may help advance research and intervention development with respect to e-cigarette initiation, maintenance and cessation.

Full Text Available Xingyun Su,1 Xiaoxia Jiang,1 Xin Xu,1 Weibin Wang,1 Xiaodong Teng,2 Anwen Shao,3 Lisong Teng1 1Department of Surgical Oncology, 2Department of Pathology, First Affiliated Hospital, 3Department of Neurosurgery, Second Affiliated Hospital, School of Medicine, Zhejiang University, Hangzhou, People’s Republic of China Abstract: Fine-needle aspiration (FNA is a reliable method for preoperative diagnosis of thyroid nodules; however, about 10%–40% nodules are classified as indeterminate. The BRAFV600E mutation is the most promising marker for thyroid FNA. This meta-analysis was conducted to investigate the diagnostic value of BRAFV600E analysis in thyroid FNA, especially the indeterminate cases. Systematic searches were performed in PubMed, Web of Science, Scopus, Ovid, Elsevier, and the Cochrane Library databases for relevant studies prior to June 2015, and a total of 88 studies were ultimately included in this meta-analysis. Compared with FNA cytology, the synergism of BRAFV600E testing increased the diagnostic sensitivity from 81.4% to 87.4% and decreased the false-negative rate from 8% to 5.2%. In the indeterminate group, the mutation rate of BRAFV600E was 23% and varied in different subcategories (43.2% in suspicious for malignant cells [SMC], 13.77% in atypia of undetermined significance/follicular lesion of undetermined significance [AUS/FLUS], and 4.43% in follicular neoplasm/suspicious for follicular neoplasm [FN/SFN]. The sensitivity of BRAFV600E analysis was higher in SMC than that in AUS/FLUS and FN/SFN cases (59.4% vs 40.1% vs 19.5% respectively, while specificity was opposite (86.1% vs 99.5% vs 99.7% respectively. The areas under the summary receiver-operating characteristic curve also confirmed the diagnostic value of BRAFV600E testing in SMC and AUS/FLUS rather than FN/SFN cases. Therefore, BRAFV600E analysis can improve the diagnostic accuracy of thyroid FNA, especially indeterminate cases classified as SMC, and select malignancy

1986-01-01

Final results from the Berkeley-Northwestern-TRIUMF muon decay experiment are summarized. If right-handed neutrinos are less massive than ∼ 6 MeV, the mass of a possible right-handed W 2 must exceed 514 GeV (with no mixing of left- and right-handed gauge bosons), or 432 GeV (with any mixing). Stringent limits are also set on left-right mixing, on non-V,A components of charged weak interactions, and on the energy scales for lepton compositeness and family symmetry breaking. 10 refs.; 5 figs

results. METHODS: All newborn infants admitted to our neonatal intensive care unit from March 1997 through December 1998 were prospectively evaluated just at completion of 24 hours of life for SNAP and SNAP-PE. Exclusion criteria were: death or discharge from the neonatal intensive care unit in the first 24 hours of life, congenital malformations incompatible with life, and outborn infants. RESULTS: 553 newborn infants were included in the study and 54 died. The median SNAP and SNAP-PE values were higher in those who died. Infants were allocated to five different raising ranges of SNAP and SNAP-PE severity. SNAP: up to 6, 7-11, 12-15, 16-24, higher than 24 (mortality: 3%, 11%, 29%, 48%,75%, respectively. SNAP-PE: up to 11, 12-23, 24-32, 33-50, higher than 50 (mortality: 3%, 10%, 53%, 78%, 83%, respectively. The optimal cut off points based on ROC curve were 12 for SNAP, and 24 for SNAP-PE. Sensitivity, specificity, positive predictive value (PPV, and negative predictive value (NPV for death were figured out. SNAP 12: sensitivity 79.6%, specificity 71.7%, PPV 23.4%, NPV 97%. SNAP-PE 24: sensitivity 79.6%, specificity 80%, PPV 30%, NPV 97.3%. The area under the curve (Az were 81.4% for SNAP, and 85.1% for SNAP-PE, both statistically significant. There were no statistical differences between the two areas under the curve. CONCLUSIONS: SNAP and SNAP-PE are excellent predictors of neonatal survival. Therefore, we recommend their use in Neonatal Intensive Care Units.

Hadron production in e⁺e^- annihilation at BABAR, and implication for the muon anomalous magnetic moment

The BABAR collaboration has an extensive program of studying hadronic cross sections in low-energy e⁺e^- collisions, accessible via initial-state radiation. Our measurements allow significant improvements in the precision of the predicted value of the muon anomalous magnetic moment. These improvements are necessary for illuminating the current 3.6 sigma difference between the predicted and the experimental values. We have published results on a number of processes with two to six hadrons in the final state. We report here the results of recent studies with final states that constitute the main contribution to the hadronic cross section in the energy region between 1 and 3 GeV, as e⁺e^- → K⁺K^-, π⁺π^-, and e⁺e^- → 4 hadrons

Exploring intrinsic, instrumental, and relational values for sustainable management of social-ecological systems

Full Text Available The values (i.e., importance that people place on ecosystems have been identified as a crucial dimension of sustainable management of social-ecological systems. Recently, the call for integrating plural values of ecosystems beyond intrinsic and instrumental values has prompted the notion of "relational values." With the aim of contributing to environmental management, we assess the environmental motivations (i.e., egoistic, biospheric, altruistic and values that people attribute to the ecosystems of the mid-upper stream of the Otún River watershed, central Andes, Colombia. We analyzed 589 questionnaires that were collected in urban and rural areas of the Otún River watershed using the nonparametric Mann-Whitney U test and logistic regressions. We found salient biospheric motivations and the attribution of plural values (i.e., intrinsic, relational, and instrumental to the ecosystems of the mid-upper stream of the Otún River watershed. Particularly, relational values were the most frequently mentioned value domain. Further, our results showed that environmental motivations and socioeconomic factors are associated with the expression of different value domains. We found negative associations between egoistic motivations and intrinsic values and between rural respondents and instrumental values. We found positive associations between altruistic motivations and relational values and between rural respondents and both intrinsic and relational values. In light of our results, we argue that intrinsic, instrumental, and relational values coexist in people's narratives about the importance of ecosystems. Plural valuation approaches could be enhanced by differentiating relational from instrumental values and by expressing them in nonmonetary terms. We argue that multiple values of ecosystems expressed by rural and urban societies should be included in environmental management to tackle social conflicts and consider the diverse needs and interests of

BACKGROUND Healthcare workers (HCWs) lack familiarity with evidence-based guidelines for the prevention of healthcare-associated infections (HAIs). There is good evidence that effective educational interventions help to facilitate guideline implementation, so we investigated whether e-learning could enhance HCW knowledge of HAI prevention guidelines. METHODS We developed an electronic course (e-course) and tested its usability and content validity. An international sample of voluntary learners submitted to a pretest (T0) that determined their baseline knowledge of guidelines, and they subsequently studied the e-course. Immediately after studying the course, posttest 1 (T1) assessed the immediate learning effect. After 3 months, during which participants had no access to the course, a second posttest (T2) evaluated the residual learning effect. RESULTS A total of 3,587 HCWs representing 79 nationalities enrolled: 2,590 HCWs (72%) completed T0; 1,410 HCWs (39%) completed T1; and 1,011 HCWs (28%) completed T2. The median study time was 193 minutes (interquartile range [IQR], 96-306 minutes) The median scores were 52% (IQR, 44%-62%) for T0, 80% (IQR, 68%-88%) for T1, and 74% (IQR, 64%-84%) for T2. The immediate learning effect (T0 vs T1) was +24% (IQR, 12%-34%; P300 minutes yielded the greatest residual effect (24%). CONCLUSIONS Moderate time invested in e-learning yielded significant immediate and residual learning effects. Decision makers could consider promoting e-learning as a supporting tool in HAI prevention. Infect Control Hosp Epidemiol 2016;37:1052-1059.

2013-01-01

Full Text Available Multiple zeta values are the numbers defined by the convergent series ζ(s1,s2,…,sk=∑n1>n2>⋯>nk>0(1/n1s1 n2s2⋯nksk, where s1, s2, …, sk are positive integers with s1>1. For k≤n, let E(2n,k be the sum of all multiple zeta values with even arguments whose weight is 2n and whose depth is k. The well-known result E(2n,2=3ζ(2n/4 was extended to E(2n,3 and E(2n,4 by Z. Shen and T. Cai. Applying the theory of symmetric functions, Hoffman gave an explicit generating function for the numbers E(2n,k and then gave a direct formula for E(2n,k for arbitrary k≤n. In this paper we apply a technique introduced by Granville to present an algorithm to calculate E(2n,k and prove that the direct formula can also be deduced from Eisenstein's double product.

Effluent monitoring: Its purpose and value

International Nuclear Information System (INIS)

Schoen, A.A.

1978-01-01

The purpose of effluent monitoring is described in terms of the primary objectives, the most important of which is to verify that the facility is functioning as it was designed and that the waste treatment and effluent control systems are performing as planned and expected. The object of a monitoring programme should be periodically re-examined to ensure that the programme serves a contemporary purpose. The value of the effluent monitoring programme is determined by the extent to which users of the monitoring data, i.e. the operator, the regulating authorities and the public, accept the result as indicating that the plant is operating safely, and in an environmentally acceptable manner. The credibility of the monitoring results is therefore the most important factor determining the value of an effluent monitoring programme. (author)

e/sup +/ -e/sup -/ hadronic multiplicity distributions

International Nuclear Information System (INIS)

Carruthers, P.; Shih, C.C.

1987-01-01

The authors have analyzed the 29 GeV multiplicity data for e/sup +/ -e/sup -/ → hadrons using the partially coherent laser distribution (PCLD). The latter interpolates between the negative binomial and Poisson distributions as the ratio S/N of coherent/incoherent multiplicity varies from zero to infinity. The negative binomial gives an excellent fit for rather large values of the cell parameter κ. Equally good fits (for full and partial rapidity range, and for the forward/backward 2 jet correlation) are obtained for the mostly coherent (almost Poissonian) PCLD with small values of κ (equal to the number of jets). The reasons for the existence of this tradeoff are explained in detail. The existence of the resulting ambiguity is traced to the insensitivity of the probability distribution to phase information in the hadronic density matrix. They recommend the study of higher order correlations (intensity interferometry) among like-sign particles to resolve this question

Weak values as context-dependent values of observables and Born's rule

International Nuclear Information System (INIS)

Hosoya, Akio; Koga, Minoru

2011-01-01

We characterize a value of an observable by a 'sum rule' for generally non-commuting observables and a 'product rule' when restricted to a maximal commuting subalgebra of observables together with the requirement that the value is unity for the projection operator of the prepared state and the values are zero for the projection operators of the states which are orthogonal to the prepared state. The crucial requirement is that the expectation value and the variance of an observable should be independent of the way of measurement, i.e. the choice of the maximal commuting subalgebra of observables. We shall call the value a 'contextual value'. We show that the contextual value of an observable coincides with the weak value advocated by Aharonov and his colleagues by demanding the consistency of quantum mechanics with Kolmogorov's measure theory of probability. This also gives a derivation of Born's rule, which is one of the axioms of conventional quantum mechanics. (paper)

Full Text Available Fibromyalgia Syndrome (FMS is a chronic pain condition characterized by pain, fatigue, and nonrestorative sleep. The disruptive symptoms of FMS are associated with reductions in quality of life related to family, intimate relationships, and work. The present study was part of a randomized pilot study of an 8-week Acceptance and Commitment Therapy (ACT intervention compared to education in a sample of 28 women with FMS. The Chronic Pain Values Inventory was administered at baseline, postintervention, and 12 week follow-up. Both groups showed significant improvements in family success, which were maintained at follow-up. Groups showed a differential pattern of success in work. The ACT group demonstrated significant, maintained improvements in success in intimate relationships, while the education group reported no changes over time. Findings suggest that both interventions may lead to improvements in valued living; however different interventions may be best suited for certain valued domains. The results of this study indicate that FMS patients are able to improve their success in family and intimate relationships and losses in these areas are not necessarily permanent.

Full Text Available Most finance textbooks present the Weighted Average Cost of Capital (WACC calculation as: WACC = Kd×(1-T×D% + Ke×E%, where Kd is the cost of debt before taxes, T is the tax rate, D% is the percentage of debt on total value, Ke is the cost of equity and E% is the percentage of equity on total value. All of them precise (but not with enough emphasis that the values to calculate D% y E% are market values. Although they devote special space and thought to calculate Kd and Ke, little effort is made to the correct calculation of market values. This means that there are several points that are not sufficiently dealt with: Market values, location in time, occurrence of tax payments, WACC changes in time and the circularity in calculating WACC. The purpose of this note is to clear up these ideas, solve the circularity problem and emphasize in some ideas that usually are looked over. Also, some suggestions are presented on how to calculate, or estimate, the equity cost of capital.

Recent results from VENUS experiments on e + e - reactions at energies between 52 and 60.8 GeV are presented. The R-values, the ratio of the total hadronic cross section to that of μ pair production, look slightly high within the present energy region. To understand this observation, a detailed study was carried out on the production of a heavy quark with |Q|=e/3. By using a next-to-leading log. approximation, the QCD cut-off parameter, Λ MS , was obtained as being Λ MS =208 MeV(+80MeV, -62MeV). The differential cross sections for e + e - → e + e - , γγ, μ + μ - , and τ + τ - were found to be consistent with predictions of the standard model. The average charge asymmetry for e + e - → qq-bar was also measured and found to be consistent with the prediction of the standard model. No evidence was observed indicating new particle production. No single photon production was observed and the upper limit of the number of light neutrino types was set to be N ν < 17.8 (90 % CL). (author)

Naturalness, value systems and perception of risk

International Nuclear Information System (INIS)

Drottz Sjoberg, B.M.

1998-01-01

Full text of publication follows: what is natural? And what is Nature? Are perceptions of Nature and naturalness related to perceptions of risk? This paper focuses on these aspects based on results from a Swedish representative sample (N=731), where subjects indicated e.g. the degree of naturalness of various phenomena, their views of nature, and personal life values, as well as perceptions of risk in specified contexts. The results showed a tendency to perceive as natural the phenomenon which is positively valued, i.e. what is natural is also good or desirable. Further, there were weak correlations between perceived naturalness and indicators of technological optimism, possibly indicating that persons with a more generous view of what is natural also more easily might accept change and outcomes due to human intelligence and activity. The construct of 'tampering with nature' has previously been shown to be one good predictor of perceived risk. The respondents also rated their agreement with items aimed to reflect the four 'views of nature' as suggested by Cultural Theory, i.e. nature as robust, capricious, tolerant and fragile. Nature was foremost perceived as fragile, but the main result clearly revealed that peoples' views of nature were complex and most often involved several of the suggested categories. The discussion focuses on the possible implications on environmental concern and risk perception given that Nature would develop into an undesirable type of locality. (author)

In Greece, due to the ongoing economic crisis a number of measures aiming at rationalising expenditure implemented. A new e-prescribing system, under a unified healthcare fund was the main pillar of these reforms focus on monitoring and auditing prescribing patterns. Main objective of this study was to document the Greek experience with the new national e-prescribing system. We analyse the dispensed prescriptions over the period 2013-2014, stratified into four levels: therapeutic subgroup, patent status, physician's specialty and geographical region. Data analysis offered a comprehensive insight into pharmaceutical expenditure over the timeframe and revealed discrepancies regarding composition of spending, brand-generic substitution within certain therapeutic subgroups, physicians' prescribing behaviour based on medical specialty, therapeutic subgroup as well as regional per capita measures. E-prescribing system is a valuable tool providing sound information to health policymakers in order to monitor and rationalize pharmaceutical expenditure, in value and volume terms.

The value of Geoheritage and implications for the assessment

Perret, Amandine; Reynard, Emmanuel

2014-05-01

Geological, geomorphological, hydrological and pedological features form with biological elements the natural heritage, which, in addition to cultural material features (historical monuments, archaeological vestiges) or intangible elements of the culture (e.g. traditions) constitute the heritage of an area, a country or even the World. Heritage recognition is the result of a complex process including the awareness of the heritage value by specialists (e.g. scientists), by militants (e.g. environmental associations) and then by large circles of the society. The emergence of this awareness often happens in times of crisis (Di Méo, 2008) (e.g. when species are close to disappear) and is not concomitant for all parts of nature or culture. Until recently geological and geomorphological features have not been fully recognized as heritage by the society. The current context of environmental crisis (climate change, overexploitation of natural resources) seems to be one of the drivers of a process of geoheritage recognition in several parts of the World. In this process, the first stage is often the selection of objects worth to be conserved and transmitted to the future generations. This selection, carried out by geoscientists, is funded on a set of values attributed to the potential heritage objects. The definition of these values is underway in the scientific community since the 1990s. Two main lines of research have emerged. (1) The first one reflects an anthropo-centred conception of Nature. These authors (e.g. Reynard, 2005) consider that the core value of geosites is their scientific importance for the knowledge of the Earth, climate and life history on the planet Earth; this central value (scientific) may be completed by several so-called additional values (e.g. ecological, cultural, aesthetic); they form together the intrinsic value of geosites. In this context, "intrinsic" is understood as inherent in the nature of the object as defined by the Earth sciences. In

Full Text Available Laboratory testing is the single highest-volume medical activity, making it useful to ask how well one can anticipate whether a given test result will be high, low, or within the reference interval ("normal". We analyzed 10 years of electronic health records--a total of 69.4 million blood tests--to see how well standard rule-mining techniques can anticipate test results based on patient age and gender, recent diagnoses, and recent laboratory test results. We evaluated rules according to their positive and negative predictive value (PPV and NPV and area under the receiver-operator characteristic curve (ROC AUCs. Using a stringent cutoff of PPV and/or NPV≥0.95, standard techniques yield few rules for sendout tests but several for in-house tests, mostly for repeat laboratory tests that are part of the complete blood count and basic metabolic panel. Most rules were clinically and pathophysiologically plausible, and several seemed clinically useful for informing pre-test probability of a given result. But overall, rules were unlikely to be able to function as a general substitute for actually ordering a test. Improving laboratory utilization will likely require different input data and/or alternative methods.

A major task for decision makers is deciding how to consider monetary, cultural and conservation values of biodiversity explicitly when planning sustainable land use. Thus, there is a great need to understand just what "valuing" biodiversity or species really means, e.g. regarding how many and which species are important in providing ecosystem services or other values. Constructing ecosystem-level indices, however, requires weighting the relative contribution of species to the different values. Using farmland birds, we illustrate how species contribute to different biodiversity values, namely utilitarian (pest seed predation potential), cultural (species occurrence in poetry), conservational (declines and rarity) and inherent (all species equal) value. Major contributions to each value are often made by a subset of the community and different species are important for different values, leading to no correlations or, in some cases, negative correlations between species' relative contributions to different values. Our results and methods using relative contributions of species to biodiversity values can aid decisions when weighing different values in policies and strategies for natural resource management. We conclude that acknowledging the importance of the range of biodiversity values that are apparent from different perspectives is critical if the full value of biodiversity to society is to be realised.

The study of the K{sub L,S} {yields} {pi}{sup +}{pi}{sup -}e{sup +}e{sup -} decay modes in the NA48 experiment at CERN is presented in this thesis. Using the full data samples collected in 1998 and 1999, 1285 {+-} 37 events K{sub L} {yields} {pi}{sup +}{pi}{sup -}e{sup +}e{sup -} have been extracted over a background of 41 events. The measured branching ratio is: BR(K{sub L} {yields} {pi}{sup +}{pi}{sup -}e{sup +}e{sup -})=[3,16{+-}0,09(stat.){+-}0,16(syst.)] x 10{sup -7}. Concerning the K{sub S} mode, a signal of 768 {+-} 28 candidates has been observed over a negligible background. The obtained branching ratio is: BR(K{sub S} {yields} {pi}{sup +}{pi}{sup -}e{sup +}e{sup -})=[4,28{+-}0,18(stat.){+-}0,26(syst.)] x 10{sup -5}. Both results are in very good agreement with the values predicted by phenomenological models where the processes K{sub L,S} {yields} {pi}{sup +}{pi}{sup -}e{sup +}e{sup -} are described in terms of inner Bremsstrahlung and direct emission contributions. In the K{sub L} mode, the presence of two components with opposed CP states leads to a large asymmetry A in the distribution of the angle {phi} between the decay planes of the two pions and the two electrons. The detailed analysis of the K{sub L} {yields} {pi}{sup +}{pi}{sup -}e{sup +}e{sup -} mode ends up to a non-zero value of the asymmetry with more than 4 standard deviations: A(K{sub L} {yields} {pi}{sup +}{pi}{sup -}e{sup +}e{sup -})=[13,8{+-}2,8(stat.){+-}2,3(syst.)]%. This result is a clear manifestation of CP violation in this channel. The large value of this asymmetry, in excellent agreement with theoretical prediction, accounts for CP violation in the K{sup 0}-K-bar{sup 0} mixing. Furthermore, it was verified that in the K{sub S} {yields} {pi}{sup +}{pi}{sup -}e{sup +}e{sup -} mode which is dominated by the inner Bremsstrahlung component, the asymmetry is compatible with zero: A(K{sub S} {yields} {pi}{sup +}{pi}{sup -}e{sup +}e{sup -})=[-0,8{+-}3,6(stat.){+-}1,2(syst.)]%.

Full Text Available Abstract Background CD4+ T lymphocyte counts are the most important indicator of disease progression and success of antiretroviral treatment in HIV infection in resource limited settings. The nationwide reference range of CD4+ T lymphocytes was not available in India. This study was conducted to determine reference values of absolute CD4+ T cell counts and percentages for adult Indian population. Methods A multicentric study was conducted involving eight sites across the country. A total of 1206 (approximately 150 per/centre healthy participants were enrolled in the study. The ratio of male (N = 645 to female (N = 561 of 1.14:1. The healthy status of the participants was assessed by a pre-decided questionnaire. At all centers the CD4+ T cell count, percentages and absolute CD3+ T cell count and percentages were estimated using a single platform strategy and lyse no wash technique. The data was analyzed using the Statistical Package for the Social Scientist (SPSS, version 15 and Prism software version 5. Results The absolute CD4+ T cell counts and percentages in female participants were significantly higher than the values obtained in male participants indicating the true difference in the CD4+ T cell subsets. The reference range for absolute CD4 count for Indian male population was 381-1565 cells/μL and for female population was 447-1846 cells/μL. The reference range for CD4% was 25-49% for male and 27-54% for female population. The reference values for CD3 counts were 776-2785 cells/μL for Indian male population and 826-2997 cells/μL for female population. Conclusion The study used stringent procedures for controlling the technical variation in the CD4 counts across the sites and thus could establish the robust national reference ranges for CD4 counts and percentages. These ranges will be helpful in staging the disease progression and monitoring antiretroviral therapy in HIV infection in India.

Pre- and post-selection, weak values and contextuality

International Nuclear Information System (INIS)

Tollaksen, Jeff

2007-01-01

By analysing the concept of contextuality (Bell-Kochen-Specker) in terms of pre- and post-selection, it is possible to assign definite values to observables in a new and surprising way. Physical reasons are presented for restrictions on these assignments. When measurements are performed which do not disturb the pre- and post-selection (i.e. weak measurements), then novel experimental aspects of contextuality can be demonstrated. We also prove that every PPS-paradox with definite predictions directly implies 'quantum contextuality' which is introduced as the analogue of contextuality at the level of quantum mechanics rather than at the level of hidden variable theories. Finally, we argue that certain results of these measurements (e.g. eccentric weak values outside the eigenvalue spectrum) cannot be explained by a 'classical-like' hidden variable theory

The instantaneous wave-free ratio (iFR) is a vasodilator-free, invasive pressure wire index of the functional severity of coronary stenosis and is calculated under resting conditions. In a recent study, iFR was found to be more closely linked to coronary flow reserve (CFR) than fractional flow reserve (FFR). E/e' is a surrogate marker of left ventricular (LV) filling pressure and LV diastolic dysfunction. Coronary resting flow was found to be increased in patients with elevated E/e', and higher coronary resting flow was associated with lower CFR. Higher baseline coronary flow induces a greater loss of translesional pressure and may affect iFR. However, no reports have examined the impact of E/e' on iFR. The purpose of this study was to assess the relationship between iFR and E/e' compared with FFR. We retrospectively examined 103 consecutive patients (142 with stenosis) whose iFR, FFR, and E/e' were measured simultaneously. The mean age, LV mass index, and systolic blood pressure of patients with elevated E/e' were higher than those of patients with normal E/e'. Although no significant differences were observed in mean FFR values and % diameter stenosis, the mean iFR value in patients with elevated E/e' was significantly lower than that in patients with normal E/e'. The iFR was negatively correlated with E/e', while there was no correlation between FFR and E/e'. Multivariate analysis showed that E/e' and % diameter stenosis were independent determinants of iFR. E/e' ratio affects iFR values. Our results suggest that FFR mainly reflects the functional severity of the epicardial stenosis whereas iFR could potentially be influenced by not only epicardial stenosis but also other factors related to LV filling pressure or LV diastolic dysfunction. Further research is needed to understand the underlying mechanisms that influence the evaluation of iFR in patients with elevated E/e'. Copyright © 2017 Japanese College of Cardiology.

Values reflect how people want to experience the world; emotions reflect how people actually experience the world. Therefore, we propose that across cultures people desire emotions that are consistent with their values. Whereas prior research focused on the desirability of specific affective states or 1 or 2 target emotions, we offer a broader account of desired emotions. After reporting initial evidence for the potential causal effects of values on desired emotions in a preliminary study (N = 200), we tested the predictions of our proposed model in 8 samples (N = 2,328) from distinct world cultural regions. Across cultural samples, we found that people who endorsed values of self-transcendence (e.g., benevolence) wanted to feel more empathy and compassion, people who endorsed values of self-enhancement (e.g., power) wanted to feel more anger and pride, people who endorsed values of openness to change (e.g., self-direction) wanted to feel more interest and excitement, and people who endorsed values of conservation (e.g., tradition) wanted to feel more calmness and less fear. These patterns were independent of differences in emotional experience. We discuss the implications of our value-based account of desired emotions for understanding emotion regulation, culture, and other individual differences.

We sought to determine the effect of patient selection on the 99th reference percentile of 2 sensitive and 1 high-sensitivity (hs) cardiac troponin assays in a well-defined reference population. Individuals>45 years old were randomly selected from 7 representative local community practices. Detailed information regarding the participants was collected via questionnaires. The healthy reference population was defined as individuals who had no history of vascular disease, hypertension, or heavy alcohol intake; were not receiving cardiac medication; and had blood pressure60 mL·min(-1)·(1.73 m2)(-1), and normal cardiac function according to results of echocardiography. Samples were stored at -70 °C until analysis for cardiac troponin I (cTnI) and cardiac troponin T (cTnT) and N-terminal pro-B-type natriuretic peptide. Application of progressively more stringent population selection strategies to the initial baseline population of 545 participants until the only individuals who remained were completely healthy according to the study criteria reduced the number of outliers seen and led to a progressive decrease in the 99th-percentile value obtained for the Roche hs-cTnT assay and the sensitive Beckman cTnI assay but not for the sensitive Siemens Ultra cTnI assay. Furthermore, a sex difference found in the baseline population for the hs-cTnT (P=0.0018) and Beckman cTnI assays (Pstrategy significantly influenced the 99th percentile reference values determined for troponin assays and the observed sex differences in troponin concentrations.

Results of our search for short lived neutral particles emitted in K + decay are given. We also seek to make an accurate measurement of the branching ratio for π 0 → e + e - by looking for the decay chain K + → π + π 0 , π 0 → e + e - . The world average branching ratio for this decay is (1.8 +- 0.7) x 10 -7 based on about 30 events from two experiments. Theory predicts that this branching ratio should be of order 6 x 10 -8 . If the branching ratio remains at the 2 x 10 -7 level when measured with smaller errors, this could be an indication of new physics. 24 refs., 7 figs

, attending high school and with different socioeconomic backgrounds. Genders and socioeconomic backgrounds were compared as to the values of beauty and intelligence assigned by adolescents to themselves. In a hypothetical and mutually exclusive manner, these characteristics were assessed to check which were the most valued for themselves and possible partners. The results demonstrated that boys with high socioeconomic background assigned higher intelligence scores for themselves. Adolescents of both genders from low socioeconomic background would like to have a higher level of intelligence instead of beauty, whereas adolescents from high socioeconomic background prefer a balance between beauty and intelligence. The girls assigned more value to intelligence in their partners than the boys, which assigned more value to beauty in their partners.

Full Text Available The chemical composition and energy value of guava and tomato wastes for broilers at different ages were determined in this research. The metabolism assays were carried out by using the methodology of total excreta collection to calculate the chemical composition of wastes collected in different months. A total of 270 COBB broiler chicks was used: 150 in the period from 1 to 8 days of age (phase 1 and 120 chicks were used in the period from 10 to 17 days of age (phase 2. The trials were analyzed as completely randomized design with three treatments with five replications of 10 and 8 birds at the respective ages. The treatments consisted of different diets: one reference diet, one with 30% tomato meal and another with 20% guava meal, both partially replacing the reference diet. The values of the chemical composition of guava and tomato wastes varied according to the collection season. The chemical composition indicated that the wastes can be used in poultry feed, but with high crude fiber contents. The values of apparent metabolizable energy and nitrogen-corrected apparent metabolizable energy and of gross energy metabolizability coefficient of guava waste was not affected by the birds age, different from the result observed for tomato waste, whose digestibility coefficients and apparent metabolizable energy values varied among growing phases. The apparent metabolizable energy values (AME for broilers form 1 to 8 and from 10 to 17 days of age were 1,331 and 1,358 kcal/kg for guava waste and from 2,351 to 2,465 kcal/kg for tomato waste.Objetivou-se determinar a composição química e os valores nergéticos dos resíduos de goiaba e de tomate para frangos de corte em diferentes idades.

Full Text Available   We present the QCD models based on the hadronization of final states of e+e- annihilations, in 60 GeV centre of mass energy in the AMY detector at the KEK collider TRISTAN. To achieve this, we first find the jet axis by using the momentum tensor and diagonilizing it for each event. The models under consideration are the Webber, the Matrix Elements and the Parton Shower. In most cases our results are consistent with the models. Our results are also consistent with those obtained from other experiments.

Immunoglobulin E-mediated allergy to cow's milk protein (CMP) tends to subside over years of follow-up. The gold standard for detecting such allergy has been the oral challenge test. The development of some other test for determining the correct timing of the oral challenge test would avoid unnecessary patient discomfort. The aim of this study was to determine whether monitoring cow's milk (CM) specific IgE levels over time can be used as a predictor for determining when patients develop clinical tolerance. A prospective 4-year follow-up study was made of 170 patients with IgE-mediated allergy to CMP, involving periodic evaluations (12, 18, 24, 36 and 48 months) with the determination of casein and CM specific IgE on each visit, along with CM challenge testing. ROC curves were used to analyse the sensitivity, specificity and predictive values of the casein and CM specific IgE levels versus the challenge test outcomes at the different moments of follow-up. In the course of follow-up, 140 infants (82 %) became tolerant. Specific IgE levels to CM: 2.58, 2.5, 2.7, 2.26, 5 kU(A)/l and to casein: 0.97, 1.22, 3, 2.39, 2.73 kU(A)/l, respectively, predicted clinical reactivity (greatest diagnostic efficiency values) at the different analysed moments of follow-up (12, 18, 24, 36 and 48 months). Quantification of CMP specific IgE is a useful test for diagnosing symptomatic allergy to CM in the paediatric population, and could eliminate the need to perform oral challenges tests in a significant number of children.

The presence of Macro prolactin is a significant cause of elevated prolactin resulting in misdiagnosis in all automated systems. Poly ethylene glycol (PEG) pretreatment is the preventive process but such process includes the probability of loss of a fraction of bioactive prolactin. Surprisingly, PEG treated EQAS & IQAS samples in Cobas e 411 are found out to be correlating with direct results of at least 3 immunoassay systems and treated and untreated Cobas e 411 results are comparable by a correlation coefficient. Comparison of EQAS, IQAS and patient samples were done to find out the trueness of such correlation factor. Study with patient's results have established the correlation coefficient is valid for very small concentration of prolactin also. EQAS, IQAS and 150 patient samples were treated with PEG and prolactin results of treated and untreated samples obtained from Roche Cobas e 411. 25 patient's results (treated) were compared with direct results in Advia Centaur, Architect I & Access2 systems. Correlation coefficient was obtained from trend line of the treated and untreated results. Two tailed p-value obtained from regression coefficient(r) and sample size.

Measurements of plasma parameters are made on the T-10 tokamak with a toroidal magnetic field of 3.5 T and a plasma current of 0.4 MA. In macroscopically stable discharges of 1 s duration, the central electron temperature is Tsub(e)(0)=1.2 keV, the mean electron density reaches a value of nsub(e)=5X10 13 cm -3 , and the central ion temperature is measured to be 0.6-0.8 keV. The thermonuclear neutron yield reaches a value of 4X10 9 neutrons per shot, in agreement with the Tsub(i)(0) value measured by charge exchange. Sawtooth X-ray oscillations are observed. The effective ionic charge is found to be less than 2 for the inner region of the plasma column. The energy confinement time tausub(E) is calculated from the experimental profiles of the plasma parameters. The value of tausub(E) is 40 ms and increases up to 60 ms, while nsub(e) is increased up to 8.5X10 13 cm -3 as a result of cold-gas injection by a pulse valve. Violent disruption is observed in several regimes. Hard-X-ray and neutron radiation bursts take place during the disruption, both in hydrogen and in deuterium. More intensive and prolonged radiation fluxes of hard X-rays and non-thermonuclear neutrons are observed in some discharges where very intensive beams of relativistic runaway electrons seem to exist.

Is place-value processing in four-digit numbers fully automatic? Yes, but not always.

García-Orza, Javier; Estudillo, Alejandro J; Calleja, Marina; Rodríguez, José Miguel

Knowing the place-value of digits in multi-digit numbers allows us to identify, understand and distinguish between numbers with the same digits (e.g., 1492 vs. 1942). Research using the size congruency task has shown that the place-value in a string of three zeros and a non-zero digit (e.g., 0090) is processed automatically. In the present study, we explored whether place-value is also automatically activated when more complex numbers (e.g., 2795) are presented. Twenty-five participants were exposed to pairs of four-digit numbers that differed regarding the position of some digits and their physical size. Participants had to decide which of the two numbers was presented in a larger font size. In the congruent condition, the number shown in a bigger font size was numerically larger. In the incongruent condition, the number shown in a smaller font size was numerically larger. Two types of numbers were employed: numbers composed of three zeros and one non-zero digit (e.g., 0040-0400) and numbers composed of four non-zero digits (e.g., 2795-2759). Results showed larger congruency effects in more distant pairs in both type of numbers. Interestingly, this effect was considerably stronger in the strings composed of zeros. These results indicate that place-value coding is partially automatic, as it depends on the perceptual and numerical properties of the numbers to be processed.

On nonepistemic values in conservation biology.

Baumgaertner, Bert; Holthuijzen, Wieteke

2017-02-01

Conservation biology is a uniquely interdisciplinary science with strong roots in ecology, but it also embraces a value-laden and mission-oriented framework. This combination of science and values causes conservation biology to be at the center of critique regarding the discipline's scientific credibility-especially the division between the realms of theory and practice. We identify this dichotomy between seemingly objective (fact-based) and subjective (value-laden) practices as the measure-value dichotomy, whereby measure refers to methods and analyses used in conservation biology (i.e., measuring biodiversity) and value refers to nonepistemic values. We reviewed and evaluated several landmark articles central to the foundation of conservation biology and concepts of biodiversity with respect to their attempts to separate measures and values. We argue that the measure-value dichotomy is false and that conservation biology can make progress in ways unavailable to other disciplines because its practitioners are tasked with engaging in both the realm of theory and the realm of practice. The entanglement of measures and values is by no means a weakness of conservation biology. Because central concepts such as biodiversity contain both factual and evaluative aspects, conservation biologists can make theoretical progress by examining, reviewing, and forming the values that are an integral part of those concepts. We suggest that values should be included and analyzed with respect to the methods, results, and conclusions of scientific work in conservation biology. © 2016 Society for Conservation Biology.

Indigenous environmental values as human values

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

Anatomy of a value proposition for laboratory medicine.

Science.gov (United States)

Price, Christopher P; St John, Andrew

2014-09-25

Value is now becoming a key driver in the ongoing development of healthcare delivery; key facets include the identification of what is valuable and how that value can be identified, leveraged, and delivered. The concept of a value proposition is widely used in business but can be used in healthcare as a statement of the benefits, costs and value that an organization can deliver to its customers. The foundation of this statement in laboratory medicine is evidence of clinical and cost effectiveness, not only for the patient, but also for other stakeholders involved in the delivery of healthcare, e.g., the carer, service provider, commissioner, purchaser, and the supplier of the test or device, as well as society as a whole. However the value of any laboratory medicine investigation is only achieved if the output (the test result(s)), is acted upon by the initiator of the investigation. Laboratory medicine is one part of a complex intervention, and so the value proposition should encompass the breadth of that intervention - from addressing the unmet need through the generation of clinical, operational and economic outcomes. A value proposition in laboratory medicine is central to successful innovation and quality improvement in healthcare. Copyright © 2014 Elsevier B.V. All rights reserved.

Managing e-government

Public sector managers take much of the responsibility for selecting, commissioning, implementing and realising benefits from information technology (IT) projects. However, e-Government initiatives often suffer from complexity, vision failure, lack of goal clarity and insufficient commitment....... These problems may stem from value traditions that are deeply ingrained in managers' cultural environments but not always in harmony with each other. A first step towards working with value complexity is to understand it; we synthesise a model of value positions for e-Government derived from major traditions...... in the public administration literature. Four value positions relevant to e-Government together with their IT assumptions are identified; they reflect the ideals of professionalism, efficiency, service and engagement. A qualitative investigation of Danish local authority managers displays both value congruence...

Many-valued logics

CERN Document Server

Bolc, Leonard

1992-01-01

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

Social Traces of Generic Humans Increase the Value of Everyday Objects.

Science.gov (United States)

Job, Veronika; Nikitin, Jana; Zhang, Sophia X; Carr, Priyanka B; Walton, Gregory M

2017-06-01

Past research finds that people behave as though the particular qualities of specific, strongly valenced individuals "rub off" on objects. People thus value a sweater worn by George Clooney but are disgusted by one worn by Hitler. We hypothesized that social traces of generic humans can also adhere to objects, increasing their value. Experiments 1 and 2 found that simply marking that consumer products (mugs, giftwrap) were made by generic strangers (e.g., "by people using machines" vs. "by machines run by people") increased their perceived value. Experiment 3 demonstrated that this effect was mediated by thoughts about attention the object received from other people, which, in turn, led people to see the object as possessing more positive social qualities (e.g., friendly), increasing valuation. The results suggest that generic humans are perceived positively, possessing warm social qualities, and these can "rub off" and adhere to everyday objects increasing their value.

A diagnostic prediction model for peanut allergy in children was recently published, using 6 predictors: sex, age, history, skin prick test, peanut specific immunoglobulin E (sIgE), and total IgE minus peanut sIgE. To validate this model and update it by adding allergic rhinitis, atopic dermatitis, and sIgE to peanut components Ara h 1, 2, 3, and 8 as candidate predictors. To develop a new model based only on sIgE to peanut components. Validation was performed by testing discrimination (diagnostic value) with an area under the receiver operating characteristic curve and calibration (agreement between predicted and observed frequencies of peanut allergy) with the Hosmer-Lemeshow test and a calibration plot. The performance of the (updated) models was similarly analyzed. Validation of the model in 100 patients showed good discrimination (88%) but poor calibration (P original model: sex, skin prick test, peanut sIgE, and total IgE minus sIgE. When building a model with sIgE to peanut components, Ara h 2 was the only predictor, with a discriminative ability of 90%. Cutoff values with 100% positive and negative predictive values could be calculated for both the updated model and sIgE to Ara h 2. In this way, the outcome of the food challenge could be predicted with 100% accuracy in 59% (updated model) and 50% (Ara h 2) of the patients. Discrimination of the validated model was good; however, calibration was poor. The discriminative ability of Ara h 2 was almost comparable to that of the updated model, containing 4 predictors. With both models, the need for peanut challenges could be reduced by at least 50%. Copyright © 2012 American Academy of Allergy, Asthma & Immunology. Published by Mosby, Inc. All rights reserved.

Search for lepton flavour violating decays of the Higgs boson to $\\mu\\tau$ and e$\\tau$ in proton-proton collisions at $\\sqrt{s}=$ 13 TeV

Energy Technology Data Exchange (ETDEWEB)

Sirunyan, Albert M; et al.

2017-12-19

A search for lepton flavour violating decays of the Higgs boson in the $\\mu\\tau$ and e$\\tau$ decay modes is presented. The search is based on a data set corresponding to an integrated luminosity of 35.9 fb$^{-1}$ of proton-proton collisions collected with the CMS detector in 2016, at a centre-of-mass energy of 13 TeV. No significant excess over the standard model expectation is observed. The observed (expected) upper limits on the lepton flavour violating branching fractions of the Higgs boson are $\\mathcal{B}$(H$\\to\\mu\\tau$) < 0.25% (0.25%) and $\\mathcal{B}$(H$\\to$e$\\tau$) < 0.61% (0.37%), at 95% confidence level. These results are used to derive upper limits on the off-diagonal $\\mu\\tau$ and e$\\tau$ Yukawa couplings $\\sqrt{|{Y_{\\mu\\tau}}|^{2}+|{Y_{\\tau\\mu}}|^{2}}<1.43\\times 10^{-3}$ and $\\sqrt{|{Y_{\\mathrm{e}\\tau}}|^{2}+|{Y_{\\tau\\mathrm{e}}}|^{2}}<2.26\\times 10^{-3}$ at 95% confidence level. The limits on the lepton flavour violating branching fractions of the Higgs boson and on the associated Yukawa couplings are the most stringent to date.

Full Text Available Today, there are many conceptions involving creation of the company value, as it is the main objective for the owners. However, there are still many companies interested primarily in the different company’s objectives and enhance its competitive position differently. The aim of the paper is to present and analyze the viewpoints of Czech and foreign specialists on the issue of company value creation. The paper provides the determination of factors positively influencing the company value, the description of their characteristics, and on the basis of a detailed academic discussion proposes conclusions. Attention is paid especially to the value drivers which are not recorded in the financial documents.The introduction of the paper gives a brief overview of the topic. The paper is divided into three main parts. The first part introduces the effective cost management. It clarifies the concept of the managerial accounting and explains its contribution to the creation of the company value. The second part deals with the external relationships of the company. It focuses on the buyer-supplier relationships and offers the detailed perspective on the specific issue of the agricultural companies and their competitiveness in relation to the land leases. The third part concentrates on the internal company environment, namely on the human capital potential and its effects on the value of the company. In the concluding part, the findings are summarized. Based on the results, the figure describing the determinants and generators of the company value is formed. This figure can be considered a systematic procedure how to create a company value.All findings are supported with the literature review e.g. Armstrong (2007, Fibírová and Šoljaková (2005, Marinič (2008, Petřík (2007 and Porter (2004.

Anwuli Irene Ofuani

2011-09-01

Full Text Available The advancement of technology has led to the rapid development of the offshore oil and gas industry and a corresponding increase in the amount of wastes generated from the industry. These wastes must be properly managed so as to curtail their potential to negatively affect human health and the environment. As a result, environmental regulation of offshore oil and gas operations is becoming more stringent worldwide. The Environmental Guidelines and Standards for the Petroleum Industry in Nigeria (EGASPIN were issued to ensure that oil and gas industry operators do not degrade the environment in the course of their operations in Nigeria. Nonetheless, more attention has been focused on the economic aspects of offshore oil and gas industry rather than environmental aspects such as waste management. This article examines the legal aspects of offshore oil and gas waste management in Nigeria. It assesses the effectiveness of the mechanisms for the management of offshore E&P wastes in Nigeria as provided under EGASPIN in relation to other jurisdictions.

The ATLAS collaboration

2018-01-01

This note presents the first collider search for light scalar particles that could contribute to the accelerating expansion of the observable universe. The results are based on a re-interpretation of a search for top super-partners using the $t\\bar{t}+E_{T}^{\\text{miss}}$ signature and a search for dark matter using the mono-jet signature. The analysis uses a dataset of LHC $pp$ collision events collected with the ATLAS detector at $\\sqrt{s}=13$ TeV corresponding to an integrated luminosity of 36.1~fb$^{-1}$. No significant excess over the predicted background is observed. The search allows to set the most stringent constraints on the suppression scale of conformal and disformal couplings of dark energy to standard model matter in the context of an effective field theory of dark energy.

The forced feeding method was utilized, by using 24 adult Leghorn roosters with means 2.35 ± 165 g. The rooster was considered as an experimental unit and each feed was given to 6 roosters (6 replicates, two replicates in each time. Simultaneously, 6 roosters were kept in fasting for determination of the endogenous and metabolic losses. Before the experimental period, each rooster was maintained without any feed for 24 hours for emptying of the digestive tract and then forced to ingest 30 grams of the test feed. For that reason, four collections of excreta were done every 12 hours, to avoid fermentation. At the end of this period, the feeds and also the excreta were homogenized for analysis of dry matter, nitrogen and gross energy and then calculated the values of energy. The values of EMVn calculated were then contrasted with values of EMVn estimated from the prediction equations presented in the national literature for groups of feeds similar to those of the present work. The values of EMVn of the soybean meals ranged from 2531 to 2730 Kcal/kg of DM and those of toasted and micronized whole soybean were 3732 and 4027 Kcal/kg of DM, respectively. For the whole soybeans and soybean meals, the equation which best estimated the values of energy were TMEn = 2690.62 - 40.87ADF + 19.96NDF + 63.09EE. In general, the equations tested in the present work shown not good estimates of the values of EMVn, so, they are not adequate to be utilized as a

Rights and Intentions in Value Modeling

Science.gov (United States)

Johannesson, Paul; Bergholtz, Maria

In order to manage increasingly complex business and IT environments, organizations need effective instruments for representing and understanding this complexity. Essential among these instruments are enterprise models, i.e. computational representations of the structure, processes, information, resources, and intentions of organizations. One important class of enterprise models are value models, which focus on the business motivations and intentions behind business processes and describe them in terms of high level notions like actors, resources, and value exchanges. The essence of these value exchanges is often taken to be an ownership transfer. However, some value exchanges cannot be analyzed in this way, e.g. the use of a service does not influence ownership. The goal of this chapter is to offer an analysis of the notion of value exchanges, based on Hohfeld's classification of rights, and to propose notation and practical modeling guidelines that make use of this analysis.

The purpose of the present study was to extend past research on the antecedents of self-objectification. We were interested in the role played by specific ideological components, i.e., higher order personal values (self-enhancement, conservation, self-transcendence, and openness to change, in influencing the degree to which individuals internalize the objectifying perspective of the Western cultural milieu, i.e., self-objectify. Undergraduate participants (N = 371, 76.8% women completed measures of self-objectification (i.e., body surveillance and body shame, and endorsement of higher order values. Regression analyses demonstrated that self-enhancement is linked to higher self-objectification in both men and women, whereas conservation is related only to women’s body surveillance. Self-transcendence seemed to act as a buffer against men’s body surveillance, whereas openness to change resulted as a buffer against women’s body surveillance. Implications are discusses.

We were interested in the role played by specific ideological components, i.e., higher order personal values (self-enhancement, conservation, self-transcendence, and openness to change), in influencing the degree to which individuals internalize the objectifying perspective of the Western cultural milieu, i.e., self-objectify. Undergraduate participants ( N = 371, 76.8% women) completed measures of self-objectification (i.e., body surveillance and body shame), and endorsement of higher order values. Regression analyses demonstrated that self-enhancement is linked to higher self-objectification in both men and women, whereas conservation is related only to women's body surveillance. Self-transcendence seemed to act as a buffer against men's body surveillance, whereas openness to change resulted as a buffer against women's body surveillance. Implications are discusses.

Using R2* values to evaluate brain tumours on magnetic resonance imaging: Preliminary results

To determine the usefulness of the R2* value in assessing the histopathological grade of glioma at magnetic resonance imaging and differentiating various brain tumours. Sixty-four patients with brain tumours underwent R2* mapping and diffusion-weighted imaging examinations. ANOVA was performed to analyse R2* values among four groups of glioma and among high-grade gliomas (grades III and IV), low-grade gliomas (grades I and II), meningiomas, and brain metastasis. Spearman's correlation coefficients were used to determine the relationships between the R2* values or apparent diffusion coefficient (ADC) and the histopathological grade of gliomas. R2* values of low- and high-grade gliomas were analysed with the receiver-operator characteristic curve. R2* values were significantly different among high-grade gliomas, low-grade gliomas, meningiomas, and brain metastasis, but not between grade I and grade II or between grade III and grade IV. The R2* value (18.73) of high-grade gliomas provided a very high sensitivity and specificity for differentiating low-grade gliomas. A strong correlation existed between the R2* value and the pathological grade of gliomas. R2* mapping is a useful sequence for determining grade of gliomas and in distinguishing benign from malignant tumours. R2* values are better than ADC for characterising gliomas. (orig.)

Thermodynamic properties of (an ester + an alkane). XVIII. Experimental HmEandVmE values for (an alkyl butanoate + an alkane) at T = 318.15 K

This work presents the experimental values of H m E andV m E obtained at a temperature of 318.15 K and atmospheric pressure for a group of 24 binary mixtures comprised of the first four alkyl butanoates (methyl to butyl) with six odd alkanes, from heptane to heptadecane. All the mixtures are endothermic, and present a regular increase in H m E with the molecular weight of the saturated hydrocarbon, while, for a same alkane, the enthalpic effects diminish with increasing alcoholic chain of the butanoate. The variation in V m E occurs in the same direction. In this paper the structural behaviour of these systems and the influence of temperature on excess properties are analysed. Experimental data are correlated with a suitable polynomial equation which is given as a function of concentration and temperature, that permits a simultaneous correlation to be established with other properties of the mixture, such as (vapour + liquid) equilibria; and acceptable results are obtained. Finally, an estimation of H m E is made with two known versions of the UNIFAC model. In the version by Dang and Tassios [J. Dang, D.P. Tassios, Ind. Eng. Chem. Process Des. Dev. 25 (1986) 22-31.], a method is proposed that considers the interaction parameters as a function of the butanoate alkanolic chain. The estimations obtained for H m E are good

As a result, besides the description of strategies and the systematization of procedures that may lead schools to succeed in implementing such proposal, we have demonstrated how an educational process based on values can help students to develop greater ethical and sociopolitical consciousness.

The value relevance of voluntary disclosure in the annual report

DEFF Research Database (Denmark)

Banghøj, Jesper; Plenborg, Thomas

2006-01-01

This paper examines if the level of voluntary disclosure affects the association between current returns and future earnings. Economic theory suggests that firms might find it advantageous to provide additional pieces of information (i.e., voluntary disclosure) to investors and analysts (Verrecchia...... 1983). Our results indicate that more voluntary disclosure does not improve the association between current returns and future earnings; i.e. current returns do not reflect more future earnings news. This finding raises the question whether voluntary information in the annual report contains value...... relevant information about future earnings or if investors are simply not capable of incorporating voluntary information in the firm value estimates. Key words: Disclosure, future earnings, informativeness...

Exact multiplicity results for quasilinear boundary-value problems with cubic-like nonlinearities

The nonlinearity $f$ is cubic-like with three distinct roots 0=a less than b less than c. By means of a quadrature method, we provide the exact number of solutions for all $lambda >0$. This way we extend a recent result, for $p=2$, by Korman et al. cite{KormanLiOuyang} to the general case $p>1$. We shall prove that when 1less than $pleq 2$ the structure of the solution set is exactly the same as that studied in the case $p=2$ by Korman et al. cite{KormanLiOuyang}, and strictly different in the case $p>2$.

Values and entrepreneurship

Full Text Available This paper deals with the importance of values ​​in business development. The authors remind M. Weber and his study about the impact of Protestantism on business development. After defining the concept of value, attention is focused on the theory of R.K. Merton, T. Parsons, R. Inglehart. Using the critical sociological approach the authors reflect on the research strategies in the area of values. In this context is mentioned for example the issue of ideal and real cultures – ideal cultures consist of norms and values to which people officially claim, e.g. values of Christian civilization, values of Central Europe; so-called universal values are very often (or should be a base for legal norms. Real cultures represent a pattern according to which people act and regard it socially acceptable. In this context is also discussed the question of individualism without responsibility that is typical for current western society as well as for the Czech society of last decades. Value orientations are patterns for expected roles, culturally defined types of human relations, expressing the basic attitudes in social interaction. The level of prevailing business values is visible also in many multinational corporations espousing the concept of corporate social responsibility within their promotion but violating it in reality.

KIMS is a dark matter search experiment using low background CsI(TB) crystals at Yangyang Underground Laboratory in Korea. With a total exposure of 3409 kg·d data, we set a new limit on WIMP-nucleon cross section. We achieved the most stringent limit on the spin-dependent interaction for a pure proton case. We were able to exclude the DAMA signal region for both spin-dependent and spin-independent interaction for the WIMP mass greater than 20 GeV/c 2 . KIMS experiment is upgraded with 12 CsI(TB) crystals corresponding to a total mass of 104 kg and accumulating data since Jan. 2008.

Rapamycin combined with anti-CD45RB mAb and IL-10 or with G-CSF induces tolerance in a stringent mouse model of islet transplantation.

Nicola Gagliani

Full Text Available BACKGROUND: A large pool of preexisting alloreactive effector T cells can cause allogeneic graft rejection following transplantation. However, it is possible to induce transplant tolerance by altering the balance between effector and regulatory T (Treg cells. Among the various Treg-cell types, Foxp3(+Treg and IL-10-producing T regulatory type 1 (Tr1 cells have frequently been associated with tolerance following transplantation in both mice and humans. Previously, we demonstrated that rapamycin+IL-10 promotes Tr1-cell-associated tolerance in Balb/c mice transplanted with C57BL/6 pancreatic islets. However, this same treatment was unsuccessful in C57BL/6 mice transplanted with Balb/c islets (classified as a stringent transplant model. We accordingly designed a protocol that would be effective in the latter transplant model by simultaneously depleting effector T cells and fostering production of Treg cells. We additionally developed and tested a clinically translatable protocol that used no depleting agent. METHODOLOGY/PRINCIPAL FINDINGS: Diabetic C57BL/6 mice were transplanted with Balb/c pancreatic islets. Recipient mice transiently treated with anti-CD45RB mAb+rapamycin+IL-10 developed antigen-specific tolerance. During treatment, Foxp3(+Treg cells were momentarily enriched in the blood, followed by accumulation in the graft and draining lymph node, whereas CD4(+IL-10(+IL-4(- T (i.e., Tr1 cells localized in the spleen. In long-term tolerant mice, only CD4(+IL-10(+IL-4(- T cells remained enriched in the spleen and IL-10 was key in the maintenance of tolerance. Alternatively, recipient mice were treated with two compounds routinely used in the clinic (namely, rapamycin and G-CSF; this drug combination promoted tolerance associated with CD4(+IL-10(+IL-4(- T cells. CONCLUSIONS/SIGNIFICANCE: The anti-CD45RB mAb+rapamycin+IL-10 combined protocol promotes a state of tolerance that is IL-10 dependent. Moreover, the combination of rapamycin+G-CSF induces

Background eHealth is widely used as a tool for improving health care delivery and information. However, distinct policies and strategies are required for its proper implementation and integration at national and international levels. Objective To determine the scope of policy issues faced by individuals, institutions, or governments in implementing eHealth programs. Methods We conducted a structured review of both peer-reviewed and gray literature from 1998–2008. A Medline search for peer-reviewed articles found 40 papers focusing on different aspects of eHealth policy. In addition, a Google search found 20 national- and international-level policy papers and documents. We reviewed these articles to extract policy issues and solutions described at different levels of care. Results The literature search found 99 policy issues related to eHealth. We grouped these issues under the following themes: (1) networked care, (2) interjurisdictional practice, (3) diffusion of eHealth/digital divide, (4) eHealth integration with existing systems, (5) response to new initiatives, (6) goal-setting for eHealth policy, (7) evaluation and research, (8) investment, and (9) ethics in eHealth. Conclusions We provide a list of policy issues that should be understood and addressed by policy makers at global, jurisdictional, and institutional levels, to facilitate smooth and reliable planning of eHealth programs.

2008-12-01

Full Text Available Abstract Background Although point-of-purchase calorie labeling at restaurants has been proposed as a strategy for improving consumer food choices, a limited number of studies have evaluated this approach. Likewise, little research has been conducted to evaluate the influence of value size pricing on restaurant meal choices. Methods To examine the effect of point-of-purchase calorie information and value size pricing on fast food meal choices a randomized 2 × 2 factorial experiment was conducted in which participants ordered a fast food meal from one of four menus that varied with respect to whether calorie information was provided and whether value size pricing was used. Study participants included 594 adolescents and adults who regularly ate at fast food restaurants. Study staff recorded the foods ordered and consumed by each participant. Participants also completed surveys to assess attitudes, beliefs and practices related to fast food and nutrition. Results No significant differences in the energy composition of meals ordered or eaten were found between menu conditions. The average energy content of meals ordered by those randomized to a menu that included calorie information and did not include value size pricing was 842 kcals compared with 827 kcals for those who ordered their meal from a menu that did not include calorie information but had value size pricing (control menu. Results were similar in most analyses conducted stratified by factors such as age, race and education level. Conclusion Additional research is needed to better evaluate the effects of calorie labeling and value size pricing on fast food meal choices. Studies in which participants are repeatedly exposed to these factors are needed since long term exposure may be required for behavior change.

In this investigation, the authors explored the impact of individuals' cultural values on their partners' relationship adjustment and perceptions of their parenting relationship. The authors examined Mexican cultural values of simpatía (i.e., harmonious interpersonal relationships) and respeto (i.e., respect for authority figures) using a sample of 50 Mexican-origin couples in southern Arizona. Congruent with their hypotheses, results supported the proposition that fathers' simpatía is positively associated with both relationship adjustment and the parenting relationship as reported by mothers, whereas fathers' respeto is negatively associated with both relationship adjustment and the parenting relationship as reported by mothers. However, the authors found little evidence of a contribution of mothers' cultural values to fathers' perceptions of either relationship adjustment or the parenting relationship. They interpret these findings to suggest that mothers' relationship adjustment and parenting relationship are more sensitive to and dependent on fathers' degree of traditional cultural values among Mexican-origin families.

This study looks at the performance of household electrical and electronic waste (WEEE) collection in 20 Italian regions from 2008 to 2015. The impact of several explicative variables on the results of e-waste collection is evaluated. The independent variables are socio-economic and demographic ones (age, gender, household size, education level, migration and income) along with technical-organisational variables (population density, presence of metropoles, macro regions, characteristics of the territory, percentage of household waste collected separately and number of e-waste collection points). The results show that the presence of collection points, the percentage of household waste collected separately and the percentage of females are positively correlated with the kg collected per inhabitant per year. For example, a variation of 1% of input (presence of collection points) corresponds to a 0.25% variation in the output (collection results) while 1% difference in the percentage of females in the population corresponds to a 7.549% difference in the collection rate. Population density, instead, is negatively correlated. It is interesting to note that there is a discrepancy between the Southern regions and the Centre regions (the former have an outcome 0.66 times lower than the latter) while the Northern regions perform similarly to the Centre ones. Moreover, the first year (2008) had a very low performance compared to the following years when the scheme constantly improved, mainly due to the additional collection points available. The Stochastic Frontier Model allows for the identification of the optimal production function among the 20 Italian regions. The best performing region is Tuscany (in the Centre), followed by Sardinia and Sicily (in the South). Copyright © 2017. Published by Elsevier Ltd.

Latina/o college students experience cultural stressors that negatively impact their mental health, which places them at risk for academic problems. We explored whether cultural values buffer the negative effect of cultural stressors on mental health symptoms in a sample of 198 Latina/o college students (70 % female; 43 % first generation college students). Bivariate results revealed significant positive associations between cultural stressors (i.e., acculturative stress, discrimination) and mental health symptoms (i.e., anxiety, depressive, psychological stress), and negative associations between cultural values of familismo, respeto, and religiosity and mental health symptoms. Several cultural values moderated the influence of cultural stressors on mental health symptoms. The findings highlight the importance of helping Latina/o college students remain connected to their families and cultural values as a way of promoting their mental health.

Combination therapy has been proposed as an alternative therapeutic approach for the treatment of Chagas disease. In this study, we evaluated the effect of treatment with benznidazole combined with E1224 (ravuconazole prodrug) in an experimental murine model of acute infection. The first set of experiments assessed the range of E1224 doses required to induce parasitological cure using Trypanosoma cruzi strains with different susceptibilities to benznidazole (Y and Colombian). All E1224 doses were effective in suppressing the parasitemia and preventing death; however, parasitological cure was observed only in mice infected with Y strain. Considering these results, we evaluated the effect of combined treatment against Colombian, a multidrug-resistant T. cruzi strain. After exclusion of antagonistic effects using in vitro assays, infected mice were treated with E1224 and benznidazole in monotherapy or in combination at day 4 or 10 postinoculation. All treatments were well tolerated and effective in suppressing parasitemia; however, parasitological and PCR assays indicated no cure among mice treated with monotherapies. Intriguingly, the outcome of combination therapy was dependent on treatment onset. Early treatment using optimal doses of E1224-benznidazole induced a 100% cure rate, but this association could not eliminate a well-established infection. The beneficial effect of combination therapy was evidenced by further reductions of the patent parasitemia period in the group receiving combined therapy compared with monotherapies. Our results demonstrated a positive interaction between E1224 and benznidazole against murine T. cruzi infection using a multidrug-resistant strain and highlighted the importance of a stringent experimental model in the evaluation of new therapies.

New measurements of W-values for protons and alpha particles

Giesen, U.; Beck, J.

2014-01-01

The increasing importance of ion beams in cancer therapy and the lack of experimental data for W-values for protons and heavy ions in air require new measurements. A new experimental set-up was developed at PTB and consistent measurements of W-values in argon, nitrogen and air for protons and alpha particles with energies from 0.7 to 3.5 MeV u -1 at PTB, and for carbon ions between 3.6 and 7.0 MeV u -1 at GSI were carried out. This publication concentrates on the measurements with protons and alpha particles at PTB. The experimental methods and the determination of corrections for recombination effects, beam-induced background radiation and additional effects are presented. W-values in argon, nitrogen and air were measured for protons with energies of 1-3 MeV and for alpha particles with energies of 2.7-14 MeV. The energies of the primary particle beam were corrected for energy losses in the gold and Mylar foils, as well as for the kinematic energy loss due to scattering by 45 deg.. Beam-induced radiation backgrounds as well as recombination effects were determined and corrected for. The present results are summarised in Figure 2 for all three gases. The solid lines through the data points for each gas indicate an average W-value for that gas. The higher values for 2.7-MeV alpha particles agree with the trend in previous data towards lower energies. They are excluded from the averages. The relative standard uncertainties of the individual data points range from 1.3 to 3 %. The weighted averages over all energies are W(Ar) = 25.7 eV, W(N 2 ) = 35.6 eV and W(Air) = 34.2 eV. The averages serve as a first comparison and the lines on the plot are to guide the eye and are not meant to imply constant W-values for all energies and particles. The W-values for protons and alpha particles in argon and nitrogen have smaller uncertainties and are lower than the suggested values, but they are still in agreement within the uncertainties. For alpha particles with energies of 12

Measurements of the differential cross sections for e + e - → μ + μ - and e + e - → τ + τ - at values of √s from 52 to 57 GeV are reported. The forward-backward asymmetries and the total cross sections for these reactions are found to be in agreement with predictions of the standard model of the electro-weak interactions. These measurements are used to extract values of the weak-coupling constants g V e g V l and g A e g A l , where l = μ or τ. (orig.)

Dry matter yield and nutritive value of forage le-gume Arachis    pintoi (Krap. & Greg. cv. Alqueire-1 (BRA 037036, was evaluated under different cutting mana-gement regimes and levels of P and K fertilization, in a yellow-red argisoil, at CAP-UFPEL, Capão do Leão, RS, Brazil during Spring-Summer and Fall. Cutting regimes compared were: no cutting, one, two, three, four and five cuttings, at 5 cm above ground. Fertilization levels con-sisted in supplying zero, 50 and 100% of requirements for P and K recommended by Brazilian Soil Science Society, for warm season perennial forage legumes. Fertilization treatments were alocated to main plots and cutting regi-mes to subplots, in a complete splitplot randomized block design, with three replications. Data of the following va-riables were submitted to analysis of variance and polino-mial regression: dry matter yield and quality of autumnal cutting, dry matter accumulation rate of autumnal cutting and total dry matter yield. If the purpose is the utilization of the forage during Autumn, 70% of the recommended phosphorus and potassium fertilization is sufficient to ob-tain maximum forage yield. However, if the objective are cuttings during the growing season (Spring-Summer and also in Autumn, it is necessary 100% of the recommended fertilization. The increase in number of cuttings during Spring-Summer decreases in the same proportion the fo-rage yield in Autumn. Forage nutritive value in Autumn is better when greater number of cuttings are made during Spring-Summer. Spring deferments also result in higher autumnal forage quality.

Values beyond value? Is anything beyond the logic of capital?

We are living in a time when it is frequently assumed that the logic of capital has subsumed every single aspect of our lives, intervening in the organization of our intimate relations as well as the control of our time, including investments in the future (e.g. via debt). The theories that document the incursion of this logic (often through the terms of neoliberalism and/or governmentality) assume that this logic is internalized, works and organizes everything including our subjectivity. These theories performatively reproduce the very conditions they describe, shrinking the domain of values and making it subject to capital's logic. All values are reduced to value. Yet values and value are always dialogic, dependent and co-constituting. In this paper I chart the history by which value eclipses values and how this shrinks our sociological imagination. By outlining the historical processes that institutionalized different organizations of the population through political economy and the social contract, producing ideas of proper personhood premised on propriety, I detail how forms of raced, gendered and classed personhood was formed. The gaps between the proper and improper generate significant contradictions that offer both opportunities to and limits on capitals' lines of flight. It is the lacks, the residues, and the excess that cannot be captured by capital's mechanisms of valuation that will be explored in order to think beyond the logic of capital and show how values will always haunt value. © London School of Economics and Political Science 2014.

Search for the rare decay π0→e+e- and measurement of the π-p→e+e-n reaction at 304 MeV/c

The experiment described was performed to measure the branching ratio for the π 0 →e + e - decay. With an accurate value for the branching ratio more can be learned about the interactions which play a role in this decay. With this experiment, information can also be obtained about the cross section for the reaction π - d→e + e - n. An upper limit of 8x10 -7 was obtained for the π 0 decay branching ratio. A value for the cross section of the π - p reaction of 68+-15 nbarn is derived. (Auth.)

This study examined whether children's values, global and abstract motivations serving as guiding principles, are organized similarly to those of adults, whether values can predict individual differences in children's sharing behaviors, and whether the normative nature of the situation influences the expression of these individual differences. Children (N=243, ages 5-12years) participated in a values ranking task as part of a visit to a science museum. The majority of children (n=150) also participated in a task examining costly sharing (i.e., sharing that results in giving up part of one's own resources) and non-costly giving (i.e., giving that does not influence one's own share). Starting from 5years of age, children showed a structure of values similar to that of adolescents and adults, specifically contrasting preferences for opposing values (i.e., self-transcendence with self-enhancement and openness to change with conservation). Importance given to self-transcendence values related positively to costly sharing but not to non-costly giving, indicating that in situations where it is more normative to share, individual differences in values are less expressed in children's actual sharing. In addition, children's sex and age moderated the relation between values and behavior. Children's values are an important aspect of their developing personalities. Taking them into consideration can greatly promote the research of prosocial and normative development as well as our understanding of individual differences in children's behavior.

The LUX (Large Underground Xenon) experiment aims at the direct detection of dark matter particles via their collisions with xenon nuclei. The 370 kg two-phase liquid xenon time projection chamber measures simultaneously the scintillation and ionization from interactions in the target. The ratio of these two signals provides very good discrimination between potential nuclear recoil and electronic recoil signals to search for WIMP-nucleon scattering. The LUX detector operates at the Sanford Underground Research Facility (Lead, South Dakota, USA) since February 2013. First results were presented in late 2013 setting the world's most stringent limits on WIMP-nucleon scattering cross-sections over a wide range of WIMP masses. A 300 day run beginning in 2014 will further improve the sensitivity and new calibration techniques will reduce systematics for the WIMP signal search.
