  1. A variable-order fractal derivative model for anomalous diffusion

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available This paper pays attention to develop a variable-order fractal derivative model for anomalous diffusion. Previous investigations have indicated that the medium structure, fractal dimension or porosity may change with time or space during solute transport processes, results in time or spatial dependent anomalous diffusion phenomena. Hereby, this study makes an attempt to introduce a variable-order fractal derivative diffusion model, in which the index of fractal derivative depends on temporal moment or spatial position, to characterize the above mentioned anomalous diffusion (or transport processes. Compared with other models, the main advantages in description and the physical explanation of new model are explored by numerical simulation. Further discussions on the dissimilitude such as computational efficiency, diffusion behavior and heavy tail phenomena of the new model and variable-order fractional derivative model are also offered.

    A general framework for deriving and using a class of constitutive laws incorporating spatial gradients of internal variables is presented. It uses two basic ingredients: a derivation of such models by homogenization techniques and a reformulation of the evolution equation at the scale of the whole structure. (orig.)

    When they are subjected to excessive loads, some materials may exhibit a softening behaviour resulting from the deterioration of their mechanical properties. To idealize such behaviours, constitutive relations with softening are introduced, for which the size of the domain of reversibility in the stress-space decreases. These models feature a strain localization within the material, in agreement with experiments, but cannot predict the subsequent behaviour because they lead to shear bands the width of which is equal to zero, physically unacceptable and numerically troublesome. It has been proposed in the literature to overcome these difficulties by adding to the list of internal variable the spatial gradients of some of them. This procedure suffers from lack of firm methodological basis. Although, some quantitative justification have been advanced relying on some kind of microscopic analysis. Therefore, we propose to extend the classical (local) models by introducing the internal state variable first gradients. Given local model within the framework of standard generalized materials, consistent homogenization procedure is put forward to derive macroscopic free energy and dissipation potentials. The standard generalized character is preserved, with an extended set of state variables, containing not only the strain and the internal variables but also the internal variable derivatives. Nevertheless, when dealing with the whole structure, the independence between the new state variables is lost. We propose then to generalize the constitutive relations, leading to a new variational principle that ensures the Clausius-Duhem inequality at the structure scale. (authors)

    1 - Description of problem or function: OCOPTR and DRVOCR are computer programs designed to find minima of non-linear differentiable functions f: R n →R with n dimensional domains. OCOPTR requires that the user only provide function values (i.e. it is a derivative-free routine). DRVOCR requires the user to supply both function and gradient information. 2 - Method of solution: OCOPTR and DRVOCR use the variable metric (or quasi-Newton) method of Davidon (1975). For OCOPTR, the derivatives are estimated by finite differences along a suitable set of linearly independent directions. For DRVOCR, the derivatives are user- supplied. Some features of the codes are the storage of the approximation to the inverse Hessian matrix in lower trapezoidal factored form and the use of an optimally-conditioned updating method. Linear equality constraints are permitted subject to the initial Hessian factor being chosen correctly. 3 - Restrictions on the complexity of the problem: The functions to which the routine is applied are assumed to be differentiable. The routine also requires (n 2 /2) + 0(n) storage locations where n is the problem dimension

  5. Dynamics with infinitely many derivatives: variable coefficient equations

    2008-01-01

    Infinite order differential equations have come to play an increasingly significant role in theoretical physics. Field theories with infinitely many derivatives are ubiquitous in string field theory and have attracted interest recently also from cosmologists. Crucial to any application is a firm understanding of the mathematical structure of infinite order partial differential equations. In our previous work we developed a formalism to study the initial value problem for linear infinite order equations with constant coefficients. Our approach relied on the use of a contour integral representation for the functions under consideration. In many applications, including the study of cosmological perturbations in nonlocal inflation, one must solve linearized partial differential equations about some time-dependent background. This typically leads to variable coefficient equations, in which case the contour integral methods employed previously become inappropriate. In this paper we develop the theory of a particular class of linear infinite order partial differential equations with variable coefficients. Our formalism is particularly well suited to the types of equations that arise in nonlocal cosmological perturbation theory. As an example to illustrate our formalism we compute the leading corrections to the scalar field perturbations in p-adic inflation and show explicitly that these are small on large scales.

    2012-10-01

    Full Text Available The increasing involvement of individuals in social media over the past decade has enabled firms to pursue new avenues in communication and sponsoring activities. Besides general research on either social media or sponsoring, questions regarding the consequences of a joint activity (sponsoring activities in social media remain unexplored. Hence, the present study analyses whether the perceived image of the brand and the celebrity endorser credibility of a top sports team influence the perceived brand value of the sponsoring firm in a social media setting. Moreover, these effects are compared between existing customers and non-customers of the sponsoring firm. Interestingly, perceived celebrity endorser credibility plays no role in forming brand value perceptions in the case of the existing customers. Implications for marketing theory and practice are derived.

    U.S. Department of Energy (DOE) Cooperative Agreement DE-FC26-98FT40321 funded through the Office of Fossil Energy and administered at the National Energy Technology Laboratory (NETL) supported the performance of a Jointly Sponsored Research Program (JSRP) at the Energy & Environmental Research Center (EERC) with a minimum 50% nonfederal cost share to assist industry in commercializing and effectively applying highly efficient, nonpolluting energy systems that meet the nation's requirements for clean fuels, chemicals, and electricity in the 21st century. The EERC in partnership with its nonfederal partners jointly performed 131 JSRP projects for which the total DOE cost share was $22,716,634 (38%) and the nonfederal share was $36,776,573 (62%). Summaries of these projects are presented in this report for six program areas: (1) resource characterization and waste management, (2) air quality assessment and control, (3) advanced power systems, (4) advanced fuel forms, (5) value-added coproducts, and (6) advanced materials. The work performed under this agreement addressed DOE goals for reductions in CO{sub 2} emissions through efficiency, capture, and sequestration; near-zero emissions from highly efficient coal-fired power plants; environmental control capabilities for SO{sub 2}, NO{sub x}, fine respirable particulate (PM{sub 2.5}), and mercury; alternative transportation fuels including liquid synfuels and hydrogen; and synergistic integration of fossil and renewable resources.

  16. Chemical equilibrium. [maximizing entropy of gas system to derive relations between thermodynamic variables

    Science.gov (United States)

    1976-01-01

    The entropy of a gas system with the number of particles subject to external control is maximized to derive relations between the thermodynamic variables that obtain at equilibrium. These relations are described in terms of the chemical potential, defined as equivalent partial derivatives of entropy, energy, enthalpy, free energy, or free enthalpy. At equilibrium, the change in total chemical potential must vanish. This fact is used to derive the equilibrium constants for chemical reactions in terms of the partition functions of the species involved in the reaction. Thus the equilibrium constants can be determined accurately, just as other thermodynamic properties, from a knowledge of the energy levels and degeneracies for the gas species involved. These equilibrium constants permit one to calculate the equilibrium concentrations or partial pressures of chemically reacting species that occur in gas mixtures at any given condition of pressure and temperature or volume and temperature.

  17. On the derivation of thermodynamic restrictions for materials with internal state variables

    International Nuclear Information System (INIS)

    Malmberg, T.

    1987-07-01

    Thermodynamic restrictions for the constitutive relations of an internal variable model are derived by evaluating the Clausius-Duhem entropy inequality with two different approaches. The classical Coleman-Noll argumentation of Rational Thermodynamics applied by Coleman and Gurtin to an internal variable model is summarized. This approach requires an arbitrary modulation of body forces and heat supply in the interior of the body which is subject to criticism. The second approach applied in this presentation is patterned after a concept of Mueller and Liu, originally developed within the context of a different entropy inequality and different classes of constitutive models. For the internal variable model the second approach requires only the modulation of initial values on the boundary of the body. In the course of the development of the second approach certain differences to the argumentation of Mueller and Liu become evident and are pointed out. Finally, the results demonstrate that the first and second approach give the same thermodynamic restrictions for the internal variable model. The derived residual entropy inequality requires further analysis. (orig.) [de

    Hydrological studies have found in data assimilation systems and global reanalysis of land surface variables (e.g soil moisture, streamflow) a wide range of applications, from drought monitoring to water balance and hydro-climatology variability assessment. Indeed, these hydrological data sources have led to an improvement in developing and testing monitoring and prediction systems in poorly gauged regions of the world. This work tests the accuracy and error of land surface variables (precipitation, soil moisture, runoff and temperature) derived from the data assimilation reanalysis products GLDAS-2 and MERRA-2. Validate the performance of these data platforms must be thoroughly evaluated in order to consider the error of hydrological variables (i.e., precipitation, soil moisture, runoff and temperature) derived from the reanalysis products. For such purpose, a quantitative assessment was performed at 2,892 climatological stations, 42 stream gauges and 44 soil moisture probes located in Mexico and across different climate regimes (hyper-arid to tropical humid). Results show comparisons between these gridded products against ground-based observational stations for 1979-2014. The results of this analysis display a spatial distribution of errors and accuracy over Mexico discussing differences between climates, enabling the informed use of these products.

  19. Employer-sponsored pension plans

    Directory of Open Access Journals (Sweden)

    2004-01-01

    Full Text Available Apart from pension plans within social insurance, in developed pension systems there are also available to individuals schemes which may to a large extent ensure a significant part of their total pension. Among them are the following: employer-sponsored pension plans or individual pension plans. The most widely used employer-sponsored pension plan in the USA is 401(k, in which both the employer and the employee contribute to the financing of the pension. These contributions as well as the return to their investment have a preferential tax treatment, i.e. do not enter a tax base. The funds are taxed only when drawn from the account in the form of a pension. This paper aims to present the functioning of 401(k pension plan as the most widely used employer sponsored pension plan in the USA, which is likely, in a modified form, to have an important place within our future reformed pension insurance system.

    Primary hyperparathyroidism is associated with a cluster of cardiovascular manifestations, including hypertension, leading to increased cardiovascular risk. The aim of our study was to investigate the ambulatory blood pressure monitoring-derived short-term blood pressure variability in patients with primary hyperparathyroidism, in comparison with patients with essential hypertension and normotensive controls. Twenty-five patients with primary hyperparathyroidism (7 normotensive,18 hypertensive) underwent ambulatory blood pressure monitoring at diagnosis, and fifteen out of them were re-evaluated after parathyroidectomy. Short-term-blood pressure variability was derived from ambulatory blood pressure monitoring and calculated as the following: 1) Standard Deviation of 24-h, day-time and night-time-BP; 2) the average of day-time and night-time-Standard Deviation, weighted for the duration of the day and night periods (24-h "weighted" Standard Deviation of BP); 3) average real variability, i.e., the average of the absolute differences between all consecutive BP measurements. Baseline data of normotensive and essential hypertension patients were matched for age, sex, BMI and 24-h ambulatory blood pressure monitoring values with normotensive and hypertensive-primary hyperparathyroidism patients, respectively. Normotensive-primary hyperparathyroidism patients showed a 24-h weighted Standard Deviation (P blood pressure higher than that of 12 normotensive controls. 24-h average real variability of systolic BP, as well as serum calcium and parathyroid hormone levels, were reduced in operated patients (P blood pressure variability is increased in normotensive patients with primary hyperparathyroidism and is reduced by parathyroidectomy, and may potentially represent an additional cardiovascular risk factor in this disease.

  1. Modes of ocean variability in the tropical Pacific as derived from GEOSAT altimetry

    Satellite-derived (GEOSAT) sea surface height anomalies for the period November 1986 to August 1989 were investigated in order to extract the dominant modes of climate variability in the tropical Pacific. Four modes are identified by applying the POP technique. The first mode has a time scale of about 3 months and can be identified with the first baroclinic equatorial Kelvin wave mode. The second mode has a time scale of about six months and describes the semi-annual cycle in tropical Pacific sea level. Equatorial wave propagation is also crucial for this mode. The third mode is the annual cycle which is dominated by Ekman dynamics. Wave propagation or reflection are found to be unimportant. The fourth mode is associated with the El Nino/Southern Oscillation (ENSO) phenomenon. The ENSO mode is found to be consistent with the 'delayed action oscillator' scenario. The results are substantiated by a companion analysis of the sea surface height variability simulated with an oceanic general circulation model (OGCM) forced by observed wind stresses for the period 1961 to 1989. The modal decomposition of the sea level variability is found to be similar to that derived from the GEOSAT data. The high consistency between the satellite and the model data indicates the high potential value of satellite altimetry for climate modeling and forecasting. (orig.)

  2. Improving evapotranspiration in a land surface model using biophysical variables derived from MSG/SEVIRI satellite

    Full Text Available Monitoring evapotranspiration over land is highly dependent on the surface state and vegetation dynamics. Data from spaceborn platforms are desirable to complement estimations from land surface models. The success of daily evapotranspiration monitoring at continental scale relies on the availability, quality and continuity of such data. The biophysical variables derived from SEVIRI on board the geostationary satellite Meteosat Second Generation (MSG and distributed by the Satellite Application Facility on Land surface Analysis (LSA-SAF are particularly interesting for such applications, as they aimed at providing continuous and consistent daily time series in near-real time over Africa, Europe and South America. In this paper, we compare them to monthly vegetation parameters from a database commonly used in numerical weather predictions (ECOCLIMAP-I, showing the benefits of the new daily products in detecting the spatial and temporal (seasonal and inter-annual variability of the vegetation, especially relevant over Africa. We propose a method to handle Leaf Area Index (LAI and Fractional Vegetation Cover (FVC products for evapotranspiration monitoring with a land surface model at 3–5 km spatial resolution. The method is conceived to be applicable for near-real time processes at continental scale and relies on the use of a land cover map. We assess the impact of using LSA-SAF biophysical variables compared to ECOCLIMAP-I on evapotranspiration estimated by the land surface model H-TESSEL. Comparison with in-situ observations in Europe and Africa shows an improved estimation of the evapotranspiration, especially in semi-arid climates. Finally, the impact on the land surface modelled evapotranspiration is compared over a north–south transect with a large gradient of vegetation and climate in Western Africa using LSA-SAF radiation forcing derived from remote sensing. Differences are highlighted. An evaluation against remote sensing derived land

    We investigate breather solutions of the generalized derivative nonlinear Schrödinger (DNLS) equation with variable coefficients, which is used in the description of femtosecond optical pulses in inhomogeneous media. The solutions are constructed by means of the similarity transformation, which reduces a particular form of the generalized DNLS equation into the standard one, with constant coefficients. Examples of bright and dark breathers of different orders, that ride on finite backgrounds and may be related to rogue waves, are presented. - Highlights: • Exact solutions of a generalized derivative NLS equation are obtained. • The solutions are produced by means of a transformation to the usual integrable equation. • The validity of the solutions is verified by comparing them to numerical counterparts. • Stability of the solutions is checked by means of direct simulations. • The model applies to the propagation of ultrashort pulses in optical media.

  4. Failure mode analysis using state variables derived from fault trees with application

    Bartholomew, R.J.

    1982-01-01

    Fault Tree Analysis (FTA) is used extensively to assess both the qualitative and quantitative reliability of engineered nuclear power systems employing many subsystems and components. FTA is very useful, but the method is limited by its inability to account for failure mode rate-of-change interdependencies (coupling) of statistically independent failure modes. The state variable approach (using FTA-derived failure modes as states) overcomes these difficulties and is applied to the determination of the lifetime distribution function for a heat pipe-thermoelectric nuclear power subsystem. Analyses are made using both Monte Carlo and deterministic methods and compared with a Markov model of the same subsystem

  5. Mantle-derived trace element variability in olivines and their melt inclusions

    Trace element variability in oceanic basalts is commonly used to constrain the physics of mantle melting and the chemistry of Earth's deep interior. However, the geochemical properties of mantle melts are often overprinted by mixing and crystallisation processes during ascent and storage. Studying primitive melt inclusions offers one solution to this problem, but the fidelity of the melt-inclusion archive to bulk magma chemistry has been repeatedly questioned. To provide a novel check of the melt inclusion record, we present new major and trace element analyses from olivine macrocrysts in the products of two geographically proximal, yet compositionally distinct, primitive eruptions from the Reykjanes Peninsula of Iceland. By combining these macrocryst analyses with new and published melt inclusion analyses we demonstrate that olivines have similar patterns of incompatible trace element (ITE) variability to the inclusions they host, capturing chemical systematics on intra- and inter-eruption scales. ITE variability (element concentrations, ratios, variances and variance ratios) in olivines from the ITE-enriched Stapafell eruption is best accounted for by olivine-dominated fractional crystallisation. In contrast, ITE variability in olivines and inclusions from the ITE-depleted Háleyjabunga eruption cannot be explained by crystallisation alone, and must have originated in the mantle. Compatible trace element (CTE) variability is best described by crystallisation processes in both eruptions. Modest correlations between host and inclusion ITE contents in samples from Háleyjabunga suggest that melt inclusions can be faithful archives of melting and magmatic processes. It also indicates that degrees of ITE enrichment can be estimated from olivines directly when melt inclusion and matrix glass records of geochemical variability are poor or absent. Inter-eruption differences in olivine ITE systematics between Stapafell and Háleyjabunga mirror differences in melt

    Circulating cell-derived microparticles (MPs) have been implicated in several disease processes and elevated levels are found in many pathological conditions. The detection and accurate measurement of MPs, although attracting widespread interest, is hampered by a lack of standardisation. The aim of this study was to establish a reliable flow cytometric assay to measure distinct subtypes of MPs in disease and to identify any significant causes of variability in MP quantification. Circulating MPs within plasma were identified by their phenotype (platelet, endothelial, leukocyte and annexin-V positivity (AnnV+). The influence of key variables (i.e. time between venepuncture and centrifugation, washing steps, the number of centrifugation steps, freezing/long-term storage and temperature of thawing) on MP measurement were investigated. Increasing time between venepuncture and centrifugation leads to increased MP levels. Washing samples results in decreased AnnV+MPs (P=0.002) and platelet-derived MPs (PMPs) (P=0.002). Double centrifugation of MPs prior to freezing decreases numbers of AnnV+MPs (P=0.0004) and PMPs (P=0.0004). A single freeze thaw cycle of samples led to an increase in AnnV+MPs (P=0.0020) and PMPs (P=0.0039). Long-term storage of MP samples at -80° resulted in decreased MP levels. This study found that minor protocol changes significantly affected MP levels. This is one of the first studies attempting to standardise a method for obtaining and measuring circulating MPs. Standardisation will be essential for successful development of MP technologies, allowing direct comparison of results between studies and leading to a greater understanding of MPs in disease.

    A gap-filled, quality assessed eddy covariance dataset has recently become available for the AmeriFluxnetwork. This dataset uses standard processing and produces commonly used science variables. This shared dataset enables robust comparisons across different analyses. Of course, there are many remaining questions. One of those is how to define 'during the day' which is an important concept for many analyses. Some studies have used local time — for example 9am to 5pm; others have used thresholds on photosynthetic active radiation (PAR). A related question is how to derive quantities such as the Bowen ratio. Most studies compute the ratio of the averages of the latent heat (LE) and sensible heat (H). In this study, we use different methods of defining 'during the day' for GPP, LE, and H. We evaluate the differences between methods in two ways. First, we look at a number of statistics of GPP. Second, we look at differences in the derived Bowen ratio. Our goal is not science per se, but rather informatics in support of the science.

  9. A Method to Derive Monitoring Variables for a Cyber Security Test-bed of I and C System

    International Nuclear Information System (INIS)

    2013-01-01

    In the IT field, monitoring techniques have been developed to protect the systems connected by networks from cyber attacks and incidents. For the development of monitoring systems for I and C cyber security, it is necessary to review the monitoring systems in the IT field and derive cyber security-related monitoring variables among the proprietary operating information about the I and C systems. Tests for the development and application of these monitoring systems may cause adverse effects on the I and C systems. To analyze influences on the system and safely intended variables, the construction of an I and C system Test-bed should be preceded. This article proposes a method of deriving variables that should be monitored through a monitoring system for cyber security as a part of I and C Test-bed. The surveillance features and the monitored variables of NMS(Network Management System), a monitoring technique in the IT field, were reviewed in section 2. In Section 3, the monitoring variables for an I and C cyber security were derived by the of NMS and the investigation for information used for hacking techniques that can be practiced against I and C systems. The monitoring variables of NMS in the IT field and the information about the malicious behaviors used for hacking were derived as expected variables to be monitored for an I and C cyber security research. The derived monitoring variables were classified into the five functions of NMS for efficient management. For the cyber security of I and C systems, the vulnerabilities should be understood through a penetration test etc. and an assessment of influences on the actual system should be carried out.

    In the IT field, monitoring techniques have been developed to protect the systems connected by networks from cyber attacks and incidents. For the development of monitoring systems for I and C cyber security, it is necessary to review the monitoring systems in the IT field and derive cyber security-related monitoring variables among the proprietary operating information about the I and C systems. Tests for the development and application of these monitoring systems may cause adverse effects on the I and C systems. To analyze influences on the system and safely intended variables, the construction of an I and C system Test-bed should be preceded. This article proposes a method of deriving variables that should be monitored through a monitoring system for cyber security as a part of I and C Test-bed. The surveillance features and the monitored variables of NMS(Network Management System), a monitoring technique in the IT field, were reviewed in section 2. In Section 3, the monitoring variables for an I and C cyber security were derived by the of NMS and the investigation for information used for hacking techniques that can be practiced against I and C systems. The monitoring variables of NMS in the IT field and the information about the malicious behaviors used for hacking were derived as expected variables to be monitored for an I and C cyber security research. The derived monitoring variables were classified into the five functions of NMS for efficient management. For the cyber security of I and C systems, the vulnerabilities should be understood through a penetration test etc. and an assessment of influences on the actual system should be carried out. Thus, constructing a test-bed of I and C systems is necessary for the safety system in operation. In the future, it will be necessary to develop a logging and monitoring system for studies on the vulnerabilities of I and C systems with test-beds.

    The analysis of injection tests under nonisothermic conditions is important for the accurate estimation of the reservoir permeability and the well's skin factor; since previously an isothermical system was assumed without taking into account a moving temperature front which expands with time plus the consequent changes in both viscosity and mobility between the cold and the hot zone of the reservoir which leads to unreliable estimation of the reservoir and well parameters. To construct the solution an analytical approach presented by Boughrara and Peres (2007) was used. That solution was initially introduced for the calculation of the injection pressure in an isothermic system. It was later modified by Boughrara and Reynolds (2007) to consider a system with variable temperature in vertical wells. In this work, the pressure response was obtained by numerical solution of the anisothermical model using the Gauss Quadrature method to solve the integrals, and assuming that both injection and reservoir temperatures were kept constant during the injection process and the water saturation is uniform throughout the reservoir. For interpretation purposes, a technique based upon the unique features of the pressure and pressure derivative curves were used without employing type-curve matching (TDS technique). The formulation was verified by its application to field and synthetic examples. As expected, increasing reservoir temperature causes a decrement in the mobility ratio, then estimation of reservoir permeability is some less accurate from the second radial flow, especially, as the mobility ratio increases

    We compared classic ECG-derived versus a mobile approach to heart rate variability (HRV) measurement. 29 young adult healthy volunteers underwent a simultaneous recording of heart rate using an ECG and a chest heart rate monitor at supine rest, during mental stress and active standing. Mean RR interval, Standard Deviation of Normal-to-Normal (SDNN) of RR intervals, and Root Mean Square of the Successive Differences (RMSSD) between RR intervals were computed in 168 pairs of 5-minute epochs by in-house software on a PC (only sinus beats) and by mobile application "ELITEHRV" on a smartphone (no beat type identification). ECG analysis showed that 33.9% of the recordings contained at least one non-sinus beat or artefact, the mobile app did not report this. The mean RR intervals were significantly longer (p = 0.0378), while SDNN (p = 0.0001) and RMSSD (p = 0.0199) were smaller for the mobile approach. Measures of identical HRV parameters by ECG-based and mobile approaches are not equivalent. Copyright © 2018 Elsevier B.V. All rights reserved.

    2017-01-01

    Physical contaminants (glass, metal, plastic and 'other') and stones were isolated and categorised from three finished commercial composts derived from source segregated biodegradable municipal waste (BMW). A subset of the identified physical contaminant fragments were subsequently reintroduced into the cleaned compost samples and sent to three commercial laboratories for testing in an inter-laboratory trial using the current PAS100:2011 method (AfOR MT PC&S). The trial showed that the 'other' category caused difficulty for all three laboratories with under reporting, particularly of the most common 'other' contaminants (paper and cardboard) and, over-reporting of non-man-made fragments. One laboratory underreported metal contaminant fragments (spiked as silver foil) in three samples. Glass, plastic and stones were variably underreported due to miss-classification or over reported due to contamination with compost (organic) fragments. The results are discussed in the context of global physical contaminant test methods and compost quality assurance schemes. Copyright © 2016 Elsevier Ltd. All rights reserved.

  14. Temporal variability in SeaWiFS derived apparent optical properties in European seas

    2010-02-01

    The 10-year record of ocean color data provided by the SeaWiFS mission is an important asset for monitoring and research activities conducted on the optically complex European seas. This study makes use of the SeaWiFS data set of normalized water leaving radiances LWN to study the major characteristics of temporal variability associated with optical properties across the entire European domain. Specifically, the time series of LWN and associated band ratios are decomposed into terms representing a fixed seasonal cycle, irregular variations and trends, and the contribution of these components to the total variance is described for the various basins. The diversity of the European waters is fully reflected by the range of results varying with regions and wavelengths. Generally, the Mediterranean and Baltic seas appear as two end-members with, respectively, high and low contributions of the seasonal component to the total variance. The existence of linear trends affecting the satellite products is also explored for each basin. By focusing the analysis on LWN and band ratios, the validity of the results is not limited by the varying levels of uncertainty that characterize derived products such as the concentration of chlorophyll a in optically complex waters. Statistically significant, and in some cases large, trends are detected in the Atlantic Ocean west of the European western shelf, the central North Sea, the English Channel, the Black Sea, the northern Adriatic, and various regions of the Mediterranean Sea and the northern Baltic Sea, revealing changes in the concentrations of optically significant constituents in these regions.

    2016-06-01

    Full Text Available Skin factor is often regarded as a constant in most of the mathematical model for well test analysis in oilfields, but this is only a kind of simplified treatment with the actual skin factor changeable. This paper defined the average permeability of a damaged area as a function of time by using the definition of skin factor. Therefore a relationship between a variable skin factor and time was established. The variable skin factor derived was introduced into existing traditional models rather than using a constant skin factor, then, this newly derived mathematical model for well test analysis considering variable skin factor was solved by Laplace transform. The dimensionless wellbore pressure and its derivative changed with dimensionless time were plotted with double logarithm and these plots can be used for type curve fitting. The effects of all the parameters in the expression of variable skin factor were analyzed based on the dimensionless wellbore pressure and its derivative. Finally, actual well testing data were used to fit the type curves developed which validates the applicability of the mathematical model from Sheng-2 Block, Shengli Oilfield, China.

    Forget the headphones you saw in the Warner Brothers thriller Contact, as well as the guttural throbs emanating from loudspeakers at the Very Large Array in that 1997 movie. In real life, radio telescopes aren't used for "listening" to anything - just like visible-light telescopes, they are used primarily to make images of astronomical objects. Now, the National Radio Astronomy Observatory (NRAO) wants to encourage astronomers to use radio-telescope data to make truly compelling images, and is offering cash prizes to winners of a new image contest. Radio Galaxy Fornax A Radio Galaxy Fornax A Radio-optical composite image of giant elliptical galaxy NGC 1316, showing the galaxy (center), a smaller companion galaxy being cannibalized by NGC 1316, and the resulting "lobes" (orange) of radio emission caused by jets of particles spewed from the core of the giant galaxy Click on image for more detail and images CREDIT: Fomalont et al., NRAO/AUI/NSF "Astronomy is a very visual science, and our radio telescopes are capable of producing excellent images. We're sponsoring this contest to encourage astronomers to make the extra effort to turn good images into truly spectacular ones," said NRAO Director Fred K.Y. Lo. The contest, offering a grand prize of $1,000, was announced at the American Astronomical Society's meeting in Minneapolis, Minnesota. The image contest is part of a broader NRAO effort to make radio astronomical data and images easily accessible and widely available to scientists, students, teachers, the general public, news media and science-education professionals. That effort includes an expanded image gallery on the observatory's Web site.

    Cushing's syndrome is associated with high cardiovascular morbility and mortality. Blood pressure (BP) variability within a 24-h period is increasingly recognized as an independent predictor of cardiovascular risk. The aim of our study was to investigate the short-term BP variability indices in Cushing's syndrome. Twenty-five patients with Cushing's syndrome (mean age 49 ± 13 years, 4 males; 21 Cushing's disease and 4 adrenal adenoma patients) underwent 24-h ambulatory BP monitoring (ABPM) and evaluation of cardiovascular risk factors. Cushing patients were divided into 8 normotensive (NOR-CUSH) and 17 hypertensive (HYP-CUSH) patients and were compared with 20 normotensive (NOR-CTR) and 20 hypertensive (HYP-CTR) age-, sex-, and BMI-matched control subjects. Short-term BP variability was derived from ABPM and calculated as the following: (1) standard deviation (SD) of 24-h, daytime, and nighttime BP; (2) 24-h weighted SD of BP; and (3) average real variability (ARV), i.e., the average of the absolute differences between consecutive BP measurements over 24 h. In comparison with controls, patients with Cushing's syndrome, either normotensive or hypertensive, had higher 24-h and daytime SD of BP, as well as higher 24-h weighted SD and ARV of BP (P = 0.03 to P CUSH or between HYP-CTR and HYP-CUSH subgroups. ABPM-derived short-term BP variability is increased in Cushing's syndrome, independent of BP elevation. It may represent an additional cardiovascular risk factor in this disease. The role of excess cortisol in BP variability has to be further clarified.

    Multi-wavelength Hubble Space Telescope (HST) images of Jupiter from the Outer Planets Atmospheres Legacy (OPAL) and Wide Field Coverage for Juno (WFCJ) programs in 2015, 2016, and 2017 are used to derive wind profiles as a function of latitude and longitude. Wind profiles are typically zonally averaged to reduce measurement uncertainties. However, doing this destroys any variations of the zonal-component of winds in the longitudinal direction. Here, we present the results derived from using a "sliding-window" correlation method. This method adds longitudinal specificity, and allows for the detection of spatial variations in the zonal winds. Spatial variations are identified in two jets: 1 at 17 ° N, the location of a prominent westward jet, and the other at 7 ° S, the location of the chevrons. Temporal and spatial variations at the 24°N jet and the 5-μm hot spots are also examined.

  6. Composition variability in soy-derived dietary supplements designated for menopausal symptom prevention

    Full Text Available An increasing number of soy isoflavone supplements are commercialized and many investigations are conducted to define their real impact on human health. The presence of other compounds (soyasaponins, phytosterols, polyunsaturated fatty acids… is rarely considered when discussing the bioactivity of an isoflavone-enriched product. Moreover, the process used can modify the phytochemical content and composition of the final product. This report evaluated the variability in content and composition of isoflavones as well as soyasaponins, proteins, fatty acids and α-galactooligosaccharides of 25 soy based dietary supplements. For isoflavones and soyasaponins, analyzed by high performance liquid chromatography coupled with an ultraviolet detector (HPLC/UV, the ‘intra product’variability was investigated by analyzing two different lots of five of these 25 dietary supplements. Proteins were determined through the quantification of total nitrogen by an elementar analyzer, fatty acids by gaz chromatography, and α-galactooligosaccharides were analyzed using a refractive index detector. These components showed a high variability: the total isoflavone contents, expressed as aglycone equivalents, varied from 4.4 mg/g (16.7 lmol/g to 95.3 mg/g (365.6 lmol/g, and the isoflavones/ soyasaponins ratio varied from 0.9 (more saponins than isoflavones to 12.9. In the same way, the protein contents ranged from 0.4 to 42.9%, and the lipid contents from 1.6 to 20%. A high variability was also observed in the profiles of these metabolites. All these differences allowed us to distinguish two main classes of dietary supplements; the whole seed based products, with genistein occurring as the major isoflavone, and the soy germ based products, with a low genistein but high glycitein content. Soy germ and whole seed based products displayed also very contrasted profiles for the other components. An additional variability, more related to the process used, was detected

    In some risk areas water erosion as the present task has got the strong influence on agriculture and can threaten inhabitants. In our country combination of USLE and RUSLE models has been used for water erosion assessment (Krása et al., 2013). Role of vegetation cover is characterized by the help of vegetation protection factor, so-called C- factor. Value of C-factor is given by the ratio of washing-off on a plot with arable crops to standard plot which is kept as fallow regularly spud after any rain (Janeček et al., 2012). Under conditions we cannot identify crop structure and its turn, determination of C-factor can be problem in large areas. In such case we only determine C-factor according to the average crop representation. New technologies open possibilities for acceleration and specification of the approach. Present-day approach for the C-factor determination is based on the analysis of multispectral image data. Red and infrared spectrum is extracted and these parts of image are used for computation of vegetation index series (NDVI, TSAVI). Acquired values for fractional time sections (during vegetation period) are averaged out. At the same time values of vegetation indices for a forest and cleared area are determined. Also regressive coefficients are computed. Final calculation is done by the help of regressive equations expressing relation between values of NDVI and C-factor (De Jong, 1994; Van der Knijff, 1999; Karaburun, 2010). Up-to-date land use layer is used for the determination of erosion threatened areas on the base of selection of individual landscape segments of erosion susceptible categories of land use. By means of Landsat 7 data C-factor has been determined for the whole area of the Czech Republic in every month of the year of 2014. At the model area in a small watershed C-factor has been determined by the conventional (tabular) procedure. Analysis was focused on: i) variability assessment of C-factor values while using the conventional

    Full Text Available Aim. To determine the lifetime of the mutagenic cytosine derivatives through the investigation of the physicochemical mechanisms of their intramolecular proton transfer. Methods. Non-empirical quantum chemistry, the analysis of the electron density by means of Bader’s atoms in molecules (AIM theory and physicochemical kinetics were used. Results. It is shown that the modification of all investigated compounds, except DCyt, prevents their pairing in both mutagenic and canonical tautomeric forms with a base which is an interacting partner. This effect can inhibit their mutagenic potential. It is also established that Watson-Crick tautomeric hypothesis can be formally expanded for the investigated molecules so far as a lifetime of the mutagenic tautomers much more exceeds characteristic time for the incorporation of one nucleotides pair by DNA biosynthesis machinery. It seems that just within the frame of this hypothesis it will be possible to give an adequate explanation of the mechanisms of mutagenic action of N4-aminocytosine, N4-methoxycytosine, N4-hydroxycytosine and N4dehydrocytosine, which have much more energy advantageous imino form in comparison with amino form. Conclusions. For the first time the comprehensive conformational analysis of a number of classical mutagens, namely cytosine derivatives, has been performed using the methods of non-empirical quantum chemistry at the MP2/6-311++G (2df,pd//B3LYP/6-311++G(d,p level of theory

    1998-07-01

    We report spatial variability of oceanic phycoerythrin spectral types detected by means of a blue spectral shift in airborne laser-induced fluorescence emission. The blue shift of the phycoerythrobilin fluorescence is known from laboratory studies to be induced by phycourobilin chromophore substitution at phycoerythrobilin chromophore sites in some strains of phycoerythrin-containing marine cyanobacteria. The airborne 532-nm laser-induced phycoerythrin fluorescence of the upper oceanic volume showed distinct segregation of cyanobacterial chromophore types in a flight transect from coastal water to the Sargasso Sea in the western North Atlantic. High phycourobilin levels were restricted to the oceanic (oligotrophic) end of the flight transect, in agreement with historical ship findings. These remotely observed phycoerythrin spectral fluorescence shifts have the potential to permit rapid, wide-area studies of the spatial variability of spectrally distinct cyanobacteria, especially across interfacial regions of coastal and oceanic water masses. Airborne laser-induced phytoplankton spectral fluorescence observations also further the development of satellite algorithms for passive detection of phytoplankton pigments. Optical modifications to the NASA Airborne Oceanographic Lidar are briefly described that permitted observation of the fluorescence spectral shifts.

  12. Trends and inter-annual variability of methane emissions derived from 1979-1993 global CTM simulations

    2003-01-01

    Full Text Available The trend and interannual variability of methane sources are derived from multi-annual simulations of tropospheric photochemistry using a 3-D global chemistry-transport model. Our semi-inverse analysis uses the fifteen years (1979--1993 re-analysis of ECMWF meteorological data and annually varying emissions including photo-chemistry, in conjunction with observed CH4 concentration distributions and trends derived from the NOAA-CMDL surface stations. Dividing the world in four zonal regions (45--90 N, 0--45 N, 0--45 S, 45--90 S we find good agreement in each region between (top-down calculated emission trends from model simulations and (bottom-up estimated anthropogenic emission trends based on the EDGAR global anthropogenic emission database, which amounts for the period 1979--1993 2.7 Tg CH4 yr-1. Also the top-down determined total global methane emission compares well with the total of the bottom-up estimates. We use the difference between the bottom-up and top-down determined emission trends to calculate residual emissions. These residual emissions represent the inter-annual variability of the methane emissions. Simulations have been performed in which the year-to-year meteorology, the emissions of ozone precursor gases, and the stratospheric ozone column distribution are either varied, or kept constant. In studies of methane trends it is most important to include the trends and variability of the oxidant fields. The analyses reveals that the variability of the emissions is of the order of 8Tg CH4 yr-1, and likely related to wetland emissions and/or biomass burning.

    This paper presents an automatic stress-relieving music recommendation system (ASMRS) for individual music listeners. The ASMRS uses a portable, wireless photoplethysmography module with a finger-type sensor, and a program that translates heartbeat signals from the sensor to the stress index. The sympathovagal balance index (SVI) was calculated from heart rate variability to assess the user's stress levels while listening to music. Twenty-two healthy volunteers participated in the experiment. The results have shown that the participants' SVI values are highly correlated with their prespecified music preferences. The sensitivity and specificity of the favorable music classification also improved as the number of music repetitions increased to 20 times. Based on the SVI values, the system automatically recommends favorable music lists to relieve stress for individuals.

  14. Using a Budyko Derived Index to Evaluate the Internal Hydrological Variability of Catchments in Complex Terrain

    Dominguez, M.

    2017-12-01

    Headwater catchments in complex terrain typically exhibit significant variations in microclimatic conditions across slopes. This microclimatic variability in turn, modifies land surface properties presumably altering the hydrologic dynamics of these catchments. The extent to which differences in microclimate and land cover dictate the partition of water and energy fluxes within a catchment is still poorly understood. In this study, we attempt to do an assessment of the effects of aspect, elevation and latitude (which are the principal factors that define microclimate conditions) on the hydrologic behavior of the hillslopes within catchments with complex terrain. Using a distributed hydrologic model on a number of catchments at different latitudes, where data is available for calibration and validation, we estimate the different components of the water balance to obtain the aridity index (AI = PET/P) and the evaporative index (EI = AET/P) of each slope for a number of years. We use Budyko's curve as a framework to characterize the inter-annual variability in the hydrologic response of the hillslopes in the studied catchments, developing a hydrologic sensitivity index (HSi) based on the relative change in Budyko's curve components (HSi=ΔAI/ΔEI). With this method, when the HSi values of a given hillslope are larger than 1 the hydrologic behavior of that part of the catchment is considered sensitive to changes in climatic conditions, while values approaching 0 would indicate the opposite. We use this approach as a diagnostic tool to discern the effect of aspect, elevation, and latitude on the hydrologic regime of the slopes in complex terrain catchments and to try to explain observed patterns of land cover conditions on these types of catchments.

Design Cohort study. Under the Freedom of Information Act, we requested access to trial protocols approved by a research ethics committee in Denmark from October 2012 to March 2013. We received 17 consecutive protocols, which had been redacted before we got them, and nine protocols without redactions. In five additional cases, the companies refused to let the committees give us access, and in three other cases, documents were missing. Participants Not applicable. Setting Not applicable. Main outcome measure Amount and nature of redactions in 22 predefined key protocol variables. Results The redactions were most widespread in those sections of the protocol where there is empirical evidence of substantial problems with the trustworthiness of published drug trials: data analysis, handling of missing data, detection and analysis of adverse events, definition of the outcomes, interim analyses and premature termination of the study, sponsor's access to incoming data while the study is running, ownership to the data and investigators' publication rights. The parts of the text that were redacted differed widely, both between companies and within the same company. Conclusions We could not identify any legitimate rationale for the redactions. The current mistrust in industry-sponsored drug trials can only change if the industry offers unconditional access to its trial protocols and other relevant documents and data.

  16. The Political Economy of Federally Sponsored Data

    Full Text Available Librarian involvement in the Open Access (OA movement has traditionally focused on access to scholarly publications. Recent actions by the White House have focused attention on access on the data produced from federally sponsored research. Questions have emerged concerning access to the output of federally sponsored research and whether it is a public or private good. Understanding the political battle over access to federally funded research is closely tied to the ownership of the peer review process in higher education and associated revenue streams, and as a result, interest groups seeking to influence government regulation have politicized the issues. As a major funder of research in higher education, policies from the federal government are likely to drive change in research practices at higher education institutions and impact library services. The political economy of federally sponsored research data will shape research enterprises in higher education inspire a number of new services distributed throughout the research life cycle.

    Full Text Available This paper presents the first extensive reconstruction of precipitation variability in the Lesser Antilles using historical documentary sources. Over 13 250 items of documentation pertaining to Antigua from the period 1769–1890 were consulted, including missionary, plantation and governmental papers as well as contemporary scholarly publications. Based on the predominant meteorological conditions observed throughout the island, each "rain-year" (December–November was assigned one of five classifications (very wet, wet, "normal", dry and very dry. Local weather references relating to seven plantations in central-eastern Antigua were grouped according to dry (December–April and wet seasons (May–November, each of which were also categorised in the aforementioned manner. Results comprise individual island-wide and central-eastern Antiguan chronologies of relative precipitation levels, spanning the rain-years 1769–70 to 1889–90 and 1769–70 to 1853–54 respectively. The former is compared with available instrumental data for the years 1870–1890. Significant dry phases are identified in the rain-years 1775–80, 1788–91, 1820–22, 1834–37, 1844–45, 1859–60, 1862–64, 1870–74 and 1881–82, while wet episodes were 1771–74, 1833–34, 1837–38, 1841–44, 1845–46 and 1878–81. Evidence for major wet and dry spells is presented and findings are evaluated within wider historical and palaeoclimatic contexts.

    Soil erosion is an important phenomenon that contributes to the degradation of agricultural land. Even though it is a natural process, human activities can significantly increase its impact on land degradation and present serious limitation on sustainable agricultural land use. Nowadays, the risk of soil erosion is assessed either qualitatively by expert assessment or quantitatively using model-based approach. One of the primary factors affecting the soil erosion assessment is a cover-management factor, C-factor. In the Czech Republic, several models are used to assess the C-factor on a long-term basis based on data collected using traditional tabular methods. This paper presents work to investigate the estimation of both long-term and short-term cover-management factors using remote sensing data. The results demonstrate a successful development of C-factor maps for each month of 2014, growing season average, and annual average for the Czech Republic. C-factor values calculated from remote sensing data confirmed expected trend in their temporal variability for selected crops. The results presented in this paper can be used for enhancing existing methods for estimating C-factor, planning future agricultural activities, and designing technical remediations and improvement activities of land use in the Czech Republic, which are also financially supported by the European Union funds.

    Full Text Available In Lesotho, snow cover is not only highly relevant to the climate system, but also affects socio-economic factors such as water storage for irrigation or hydro-electricity. However, while sound knowledge of annual and inter-annual snow dynamics is strongly required by local stakeholders, in-situ snow information remains limited. In this study, satellite data are used to generate a time series of snow cover and to provide the missing information on a national scale. A snow retrieval method, which is based on MODIS data and considers the concept of a normalized difference snow index (NDSI, has been implemented. Monitoring gaps due to cloud cover are filled by temporal and spatial post-processing. The comparison is based on the use of clear sky reference images from Landsat-TM and ENVISAT-MERIS. While the snow product is considered to be of good quality (mean accuracy: 68%, a slight bias towards snow underestimation is observed. Based on the daily product, a consistent time series of snow cover for Lesotho from 2000–2014 was generated for the first time. Analysis of the time series showed that the high annual variability of snow coverage and the short duration of single snow events require daily monitoring with a gap-filling procedure.

  20. Variability of aerosol optical depth and Angstrom wavelength exponent derived from AERONET observations in recent decades

    2011-01-01

    Using aerosol loading data from 79 Aerosol Robotic Network (AERONET) stations with observations from more than six years, changes in aerosol optical depth (AOD) and Angstrom wavelength exponent (AWE) were studied. A statistical method was developed to determine whether AOD changes were due to increased background AOD values and/or an increased number of high AOD events. AOD decreased significantly at AERONET sites in northeastern North American and in Western Europe, which was accompanied by decreased AWE. Reduction of AOD there was mainly due to a decreased frequency of high AOD events and an increased frequency of background AOD events. In addition, decreased AOD values for high AOD events also accounted for ∼ 16–32% of the AOD reduction. This is indicative of significant meteorological effects on AOD variability. AOD trends in other regions were marginal and most were not significant; however, AOD increased significantly at one site in the Sahel and another in Saudi Arabia, predominantly due to the increased frequency of high AOD events and their average AOD.

  1. Genetic engineering of chimeric antigen receptors using lamprey derived variable lymphocyte receptors

    2016-01-01

    Full Text Available Chimeric antigen receptors (CARs are used to redirect effector cell specificity to selected cell surface antigens. Using CARs, antitumor activity can be initiated in patients with no prior tumor specific immunity. Although CARs have shown promising clinical results, the technology remains limited by the availability of specific cognate cell target antigens. To increase the repertoire of targetable tumor cell antigens we utilized the immune system of the sea lamprey to generate directed variable lymphocyte receptors (VLRs. VLRs serve as membrane bound and soluble immune effectors analogous but not homologous to immunoglobulins. They have a fundamentally different structure than immunoglobulin (Ig-based antibodies while still demonstrating high degrees of specificity and affinity. To test the functionality of VLRs as the antigen recognition domain of CARs, two VLR-CARs were created. One contained a VLR specific for a murine B cell leukemia and the other contained a VLR specific for the human T cell surface antigen, CD5. The CAR design consisted of the VLR sequence, myc-epitope tag, CD28 transmembrane domain, and intracellular CD3ζ signaling domain. We demonstrate proof of concept, including gene transfer, biosynthesis, cell surface localization, and effector cell activation for multiple VLR-CAR designs. Therefore, VLRs provide an alternative means of CAR-based cancer recognition.

    2014-01-01

    Two variable charge soils were incubated with biochars derived from straws of peanut, soybean, canola, and rice to investigate the effect of the biochars on their chemical properties and Pb(II) adsorption using batch experiments. The results showed soil cation exchange capacity (CEC) and pH signiifcantly increased after 30 d of incubation with the biochars added. The incorporation of the biochars markedly increased the adsorption of Pb(II), and both the electrostatic and non-electrostatic adsorption mechanisms contributed to Pb(II) adsorption by the variable charge soils. Adsorption isotherms illustrated legume-straw derived biochars more greatly increased Pb(II) adsorption on soils through the non-electrostatic mechanism via the formation of surface complexes between Pb(II) and acid functional groups of the biochars than did non-legume straw biochars. The adsorption capacity of Pb(II) increased, while the desorption amount slightly decreased with the increasing suspension pH for the studied soils, especially in a high suspension pH, indicating that precipitation also plays an important role in immobilizing Pb(II) to the soils.

    This research assesses the ability of a GC SCM to simulate uranium transport under variable geochemical conditions typically encountered at uranium in-situ recovery (ISR) sites. Sediment was taken from a monitoring well at the SRH site at depths 192 and 193 m below ground and characterized by XRD, XRF, TOC, and BET. Duplicate column studies on the different sediment depths, were flushed with synthesized restoration waters at two different alkalinities (160 mg/l CaCO 3 and 360 mg/l CaCO 3 ) to study the effect of alkalinity on uranium mobility. Uranium breakthrough occurred 25% - 30% earlier in columns with 360 mg/l CaCO 3 over columns fed with 160 mg/l CaCO 3 influent water. A parameter estimation program (PEST) was coupled to PHREEQC to derive site densities from experimental data. Significant parameter fittings were produced for all models, demonstrating that the GC SCM approach can model the impact of carbonate on uranium in flow systems. Derived site densities for the two sediment depths were between 141 and 178 μmol-sites/kg-soil, demonstrating similar sorption capacities despite heterogeneity in sediment mineralogy. Model sensitivity to alkalinity and pH was shown to be moderate compared to fitted site densities, when calcite saturation was allowed to equilibrate. Calcite kinetics emerged as a potential source of error when fitting parameters in flow conditions. Fitted results were compared to data from previous batch and column studies completed on sediments from the Smith-Ranch Highland (SRH) site, to assess variability in derived parameters. Parameters from batch experiments were lower by a factor of 1.1 to 3.4 compared to column studies completed on the same sediments. The difference was attributed to errors in solid-solution ratios and the impact of calcite dissolution in batch experiments. Column studies conducted at two different laboratories showed almost an order of magnitude difference in fitted site densities suggesting that experimental

    Electro-Mechanical Dual Acting Pulley (EMDAP) Continuously Variable Transmission (CVT) is a transmission utilized by electro-mechanical actuated system. It has a potential to reduce energy consumption because it only needs power during changing CVT ratio and no power is needed to maintain CVT ratio due to self lock mechanism design. This paper proposed simple proportional derivative plus conditional integral (PDCI) controller to control EMDAP CVT ratio which can be simply implemented on a microcontroller. This proposed controller used Astrom-Hagglund method and Ziegler-Nichols formula to tune PDCI gain. The Proportional Derivative controller is directly activated from the start but Integral controller is only activated when the error value reaches error value setting point. Simulation using Matlab/Simulink software was conducted to evaluate PDCI system performance. The simulation results showed PDCI controller has ability to perform maximum overshoot 0.1%, 0.001 steady state error and 0.5s settling time. For clamping condition, settling time is about 11.46s during changing ratio from 2.0 to 0.7, while for release condition, settling time is about 8.33s during changing ratio from 0.7 to 2.0.

    A lot of studies in the literature of Aerosol Optical Depth (AOD) done by using Moderate Resolution Imaging Spectroradiometer (MODIS) derived data, but the accuracy of satellite data in comparison to ground data derived from ARrosol Robotic NETwork (AERONET) has been always questionable. So to overcome from this situation, comparative study of a comprehensive ground based and satellite data for the period of 2001-2012 is modeled. The time series model is used for the accurate prediction of AOD and statistical variability is compared to assess the performance of the model in both cases. Root mean square error (RMSE), mean absolute percentage error (MAPE), stationary R-squared, R-squared, maximum absolute percentage error (MAPE), normalized Bayesian information criterion (NBIC) and Ljung-Box methods are used to check the applicability and validity of the developed ARIMA models revealing significant precision in the model performance. It was found that, it is possible to predict the AOD by statistical modeling using time series obtained from past data of MODIS and AERONET as input data. Moreover, the result shows that MODIS data can be formed from AERONET data by adding 0.251627 ± 0.133589 and vice-versa by subtracting. From the forecast available for AODs for the next four years (2013-2017) by using the developed ARIMA model, it is concluded that the forecasted ground AOD has increased trend.

    Time series of surface chlorophyll a concentration (Chl) and colored dissolved organic matter (CDOM) derived from the Ocean Color and Temperature Sensor and Sea-Viewing Wide Field-of-View Sensor were evaluated for the California Current area using regional algorithms. Satellite data composited for 8-day periods provide the ability to describe large-scale changes in surface parameters. These changes are difficult to detect based on in situ observations alone that suffer from undersampling the large temporal and spatial variability, especially in Chl. We detected no significant bias in satellite Chl estimates compared with ship-based measurements. The variability in CDOM concentration was significantly smaller than that in Chl, both spatially and temporally. While being subject to large interannual and short-term variations, offshore waters (100-1000 km from the shore) have an annual cycle of Chl and CDOM with a maximum in winter-spring (December-March) and a minimum in late summer. For inshore waters the maximum is more likely in spring (April-May). We detect significant increase in both Chl and CDOM off central and southern California during the La Niña year of 1999. The trend of increasing Chl and CDOM from October 1996 to June 2000 is statistically significant in many areas.

  17. The Complex Dynamics of Sponsored Search Markets

    Robu, Valentin; La Poutré, Han; Bohte, Sander

    This paper provides a comprehensive study of the structure and dynamics of online advertising markets, mostly based on techniques from the emergent discipline of complex systems analysis. First, we look at how the display rank of a URL link influences its click frequency, for both sponsored search and organic search. Second, we study the market structure that emerges from these queries, especially the market share distribution of different advertisers. We show that the sponsored search market is highly concentrated, with less than 5% of all advertisers receiving over 2/3 of the clicks in the market. Furthermore, we show that both the number of ad impressions and the number of clicks follow power law distributions of approximately the same coefficient. However, we find this result does not hold when studying the same distribution of clicks per rank position, which shows considerable variance, most likely due to the way advertisers divide their budget on different keywords. Finally, we turn our attention to how such sponsored search data could be used to provide decision support tools for bidding for combinations of keywords. We provide a method to visualize keywords of interest in graphical form, as well as a method to partition these graphs to obtain desirable subsets of search terms.

    Full Text Available Williamson's sapsucker (Sphyrapicus thyroideus is a migratory woodpecker that breeds in mixed coniferous forests in western North America. In Canada, the range of this woodpecker is restricted to three small populations in southern British Columbia, precipitating a national listing as 'Endangered' in 2005, and the need to characterize critical habitat for its survival and recovery. We compared habitat attributes between Williamson's sapsucker nest territories and random points without nests or detections of this sapsucker as part of a resource selection analysis to identify the habitat features that best explain the probability of nest occurrence in two separate geographic regions in British Columbia. We compared the relative explanatory power of generalized linear models based on field-derived and Geographic Information System (GIS data within both a 225 m and 800 m radius of a nest or random point. The model based on field-derived variables explained the most variation in nest occurrence in the Okanagan-East Kootenay Region, whereas nest occurrence was best explained by GIS information at the 800 m scale in the Western Region. Probability of nest occurrence was strongly tied to densities of potential nest trees, which included open forests with very large (diameter at breast height, DBH, ≥57.5 cm western larch (Larix occidentalis trees in the Okanagan-East Kootenay Region, and very large ponderosa pine (Pinus ponderosa and large (DBH 17.5-57.5 cm trembling aspen (Populus tremuloides trees in the Western Region. Our results have the potential to guide identification and protection of critical habitat as required by the Species at Risk Act in Canada, and to better manage Williamson's sapsucker habitat overall in North America. In particular, management should focus on the maintenance and recruitment of very large western larch and ponderosa pine trees.

    Science.gov (United States)

    Hopkins, Jo; Lucas, Marc; Dufau, Claire; Sutton, Marion; Lauret, Olivier

    2013-04-01

    The Congo River in Africa has the world's second highest annual mean daily freshwater discharge and is the second largest exporter of terrestrial organic carbon into the oceans. It annually discharges an average of 1,250 × 109 m3 of freshwater into the southeast Atlantic producing a vast fresh water plume, whose signature can be traced hundreds of kilometres from the river mouth. Large river plumes such as this play important roles in the ocean carbon cycle, often functioning as carbon sinks. An understanding of their extent and seasonality is therefore essential if they are to be realistically accounted for in global assessments of the carbon cycle. Despite its size, the variability and dynamics of the Congo plume are minimally documented. In this paper we analyse satellite derived sea surface temperature, salinity, ocean colour and sea level anomaly to describe and quantify the extent, strength and variability of the far-field plume and to explain its behaviour in relation to winds, ocean currents and fresh water discharge. Empirical Orthogonal Function analysis reveals strong seasonal and coastal upwelling signals, potential bimodal seasonality of the Angola Current and responses to fresh water discharge peaks in all data sets. The strongest plume-like signatures however were found in the salinity and ocean colour where the dominant sources of variability come from the Congo River itself, rather than from the wider atmosphere and ocean. These two data sets are then analysed using a statistically based water mass detection technique to isolate the behaviour of the plume. The Congo's close proximity to the equator means that the influence of the earth's rotation on the fresh water inflow is relatively small and the plume tends not to form a distinct coastal current. Instead, its behaviour is determined by wind and surface circulation patterns. The main axis of the plume between November and February, following peak river discharge, is oriented northwest, driven

  2. DOE-EERC jointly sponsored research program

    Energy Technology Data Exchange (ETDEWEB)

    Hendrikson, J.G.; Sondreal, E.A.

    1999-09-01

    U.S. Department of Energy (DOE) Cooperative Agreement DE-FC21-93MC30098 funded through the Office of Fossil Energy and administered at the Federal Energy Technology Center (FETC) supported the performance of a Jointly Sponsored Research Program (JSRP) at the Energy and Environmental Research Center (EERC) with a minimum 50% nonfederal cost share to assist industry in commercializing and effectively applying efficient, nonpolluting energy technologies that can compete effectively in meeting market demands for clean fuels, chemical feedstocks, and electricity in the 21st century. The objective of the JSRP was to advance the deployment of advanced technologies for improving energy efficiency and environmental performance through jointly sponsored research on topics that would not be adequately addressed by the private sector alone. Examples of such topics include the barriers to hot-gas cleaning impeding the deployment of high-efficiency power systems and the search for practical means for sequestering CO{sub 2} generated by fossil fuel combustion. The selection of particular research projects was guided by a combination of DOE priorities and market needs, as provided by the requirement for joint venture funding approved both by DOE and the private sector sponsor. The research addressed many different energy resource and related environmental problems, with emphasis directed toward the EERC's historic lead mission in low-rank coals (LRCs), which represent approximately half of the U.S. coal resources in the conterminous states, much larger potential resources in Alaska, and a major part of the energy base in the former U.S.S.R., East Central Europe, and the Pacific Rim. The Base and JSRP agreements were tailored to the growing awareness of critical environmental issues, including water supply and quality, air toxics (e.g., mercury), fine respirable particulate matter (PM{sub 2.5}), and the goal of zero net CO{sub 2} emissions.

    Full Text Available Bilfinger SE (Bilfinger is a leading international engineering and services group (Bilfinger.com, 2015, and was a local sponsor of the 2014 FIFA World Cup. The company is accused of paying bribes through its subsidiary company, Mauell, (dw. com, 2015 to public officials in Brazil for contracts related to the 2014 World Cup (Cassin, 2015. The corruption allegations relate to orders to equip security command centers at twelve host cities during the 2014 World Cup in Brazil (dw.com, 2015. Because Brazil hosted the 2014 FIFA World Cup and will host the 2016 Summer Olympic Games, companies need to consider the risks of many international anti-corruption laws, such as Brazil’s anti-corruption law commonly referred as The Clean Companies Act and other applicable anticorruption law like the United States’ Foreign Corrupt Practices Act (Rogers, et. al, 2014. This paper will analyze the Bilfinger case involving corruption activity at the 2014 FIFA World Cup and offer insights for sponsors of the 2016 Summer Olympic Games.

  7. Variability of the total ozone trend over Europe for the period 1950─2004 derived from reconstructed data

    Directory of Open Access Journals (Sweden)

    J. L. Borkowski

    2008-06-01

    Full Text Available The total ozone data over Europe are available for only few ground-based stations in the pre-satellite era disallowing examination of the spatial trend variability over the whole continent. A need of having gridded ozone data for a trend analysis and input to radiative transfer models stimulated a reconstruction of the daily ozone values since January 1950. Description of the reconstruction model and its validation were a subject of our previous paper. The data base used was built within the objectives of the COST action 726 "Long-term changes and climatology of UV radiation over Europe". Here we focus on trend analyses. The long-term variability of total ozone is discussed using results of a flexible trend model applied to the reconstructed total ozone data for the period 1950–2004. The trend pattern, which comprises both anthropogenic and "natural" component, is not a priori assumed but it comes from a smooth curve fit to the zonal monthly means and monthly grid values. The ozone long-term changes are calculated separately for cold (October–next year April and warm (May–September seasons. The confidence intervals for the estimated ozone changes are derived by the block bootstrapping. The statistically significant negative trends are found almost over the whole Europe only in the period 1985–1994. Negative trends up to −3% per decade appeared over small areas in earlier periods when the anthropogenic forcing on the ozone layer was weak . The statistically positive trends are found only during warm seasons 1995–2004 over Svalbard archipelago. The reduction of ozone level in 2004 relative to that before the satellite era is not dramatic, i.e., up to ~−5% and ~−3.5% in the cold and warm subperiod, respectively. Present ozone level is still depleted over many popular resorts in southern Europe and northern Africa. For high latitude regions the trend overturning could be inferred in last decade (1995–2004 as the ozone depleted

  8. Describing the interannual variability of precipitation with the derived distribution approach: effects of record length and resolution

    Directory of Open Access Journals (Sweden)

    C. I. Meier

    2016-10-01

    Full Text Available Interannual variability of precipitation is traditionally described by fitting a probability model to yearly precipitation totals. There are three potential problems with this approach: a long record (at least 25–30 years is required in order to fit the model, years with missing rainfall data cannot be used, and the data need to be homogeneous, i.e., one has to assume stationarity. To overcome some of these limitations, we test an alternative methodology proposed by Eagleson (1978, based on the derived distribution (DD approach. It allows estimation of the probability density function (pdf of annual rainfall without requiring long records, provided that continuously gauged precipitation data are available to derive external storm properties. The DD approach combines marginal pdfs for storm depths and inter-arrival times to obtain an analytical formulation of the distribution of annual precipitation, under the simplifying assumptions of independence between events and independence between storm depth and time to the next storm. Because it is based on information about storms and not on annual totals, the DD can make use of information from years with incomplete data; more importantly, only a few years of rainfall measurements should suffice to estimate the parameters of the marginal pdfs, at least at locations where it rains with some regularity. For two temperate locations in different climates (Concepción, Chile, and Lugano, Switzerland, we randomly resample shortened time series to evaluate in detail the effects of record length on the DD, comparing the results with the traditional approach of fitting a normal (or lognormal distribution. Then, at the same two stations, we assess the biases introduced in the DD when using daily totalized rainfall, instead of continuously gauged data. Finally, for randomly selected periods between 3 and 15 years in length, we conduct full blind tests at 52 high-quality gauging stations in Switzerland

    Compared the interannual variation in diatoms, cyanobacteria, coccolithophores and chlorophytes from the NASA Ocean Biogeochemical Model with those derived from satellite data (Hirata et al. 2011) between 1998 and 2006 in the Equatorial Pacific. Using NOBM, La Ni a events were characterized by an increase in diatoms (correlation with MEI, r=-0.81, Pphytoplankton community in response to climate variability. However, satellite-derived phytoplankton groups were all negatively correlated with climate variability (r ranged from -0.39 for diatoms to -0.64 for coccolithophores, Pphytoplankton groups except diatoms than NOBM. However, the different responses of phytoplankton to intense interannual events in the Equatorial Pacific raises questions about the representation of phytoplankton dynamics in models and algorithms: is a phytoplankton community shift as in the model or an across-the-board change in abundances of all phytoplankton as in the satellite-derived approach.

  12. Temporal variability in terrestrially-derived sources of particulate organic carbon in the lower Mississippi River and its upper tributaries

    Bianchi, Thomas S.; Wysocki, Laura A.; Stewart, Mike; Filley, Timothy R.; McKee, Brent A.

    2007-09-01

    In this study, we examined the temporal changes of terrestrially-derived particulate organic carbon (POC) in the lower Mississippi River (MR) and in a very limited account, the upper tributaries (Upper MR, Ohio River, and Missouri River). We used for the first time a combination of lignin-phenols, bulk stable carbon isotopes, and compound-specific isotope analyses (CSIA) to examine POC in the lower MR and upper tributaries. A lack of correlation between POC and lignin phenol abundances ( Λ8) was likely due to dilution effects from autochthonous production in the river, which has been shown to be considerably higher than previously expected. The range of δ 13C values for p-hydroxycinnamic and ferulic acids in POC in the lower river do support that POM in the lower river does have a significant component of C 4 in addition to C 3 source materials. A strong correlation between δ 13C values of p-hydroxycinnamic, ferulic, and vanillyl phenols suggests a consistent input of C 3 and C 4 carbon to POC lignin while a lack of correlation between these same phenols and POC bulk δ 13C further indicates the considerable role of autochthonous carbon in the lower MR POC budget. Our estimates indicate an annual flux of POC of 9.3 × 10 8 kg y -1 to the Gulf of Mexico. Total lignin fluxes, based on Λ8 values of POC, were estimated to be 1.2 × 10 5 kg y -1. If we include the total dissolved organic carbon (DOC) flux (3.1 × 10 9 kg y -1) reported by [Bianchi T. S., Filley T., Dria K. and Hatcher, P. (2004) Temporal variability in sources of dissolved organic carbon in the lower Mississippi River. Geochim. Cosmochim. Acta68, 959-967.], we get a total organic carbon flux of 4.0 × 10 9 kg y -1. This represents 0.82% of the annual total organic carbon supplied to the oceans by rivers (4.9 × 10 11 kg).

    In the past 25 years a trend away from lifetime commitment in religious institutes, a rising number of retired religious,, and the Second Vatican Council's call for greater lay involvement in all aspects of ministry have led to many changes in Catholic-sponsored health care facilities. The development process of religious institutes parallels that of individuals as they mature from infancy to late adulthood. After Vatican II, religious institutes underwent an "intimacy versus isolation" stage similar to that experienced by people in their twenties, in which interpersonal relationships became more important. Now institutes are in a stage of "ego integrity versus despair," where they must consider changes--closing facilities, mergers, affiliations,, or divestiture of sponsorship--and how they can keep their mission alive afterward. Religious leaders must be energetic in creating programs that allow laypersons who share the institute's mission, charism, and philosophy to carry out its ministry. But in the midst of these changes, religious members also will experience grief at the loss of their sponsorship or control over their facility. They pass through the same stages people experience after the death of a loved one: denial, anger, bargaining, depression, and acceptance. Only by confronting and accepting their grief can institute members go on to either new ministries or reaffirmed commitment to their current work.

    Purpose: To study the variability of patient-specific motion models derived from 4-dimensional CT (4DCT) images using different deformable image registration (DIR) algorithms for lung cancer stereotactic body radiotherapy (SBRT) patients. Methods: Motion models are derived by 1) applying DIR between each 4DCT image and a reference image, resulting in a set of displacement vector fields (DVFs), and 2) performing principal component analysis (PCA) on the DVFs, resulting in a motion model (a set of eigenvectors capturing the variations in the DVFs). Three DIR algorithms were used: 1) Demons, 2) Horn-Schunck, and 3) iterative optical flow. The motion models derived were compared using patient 4DCT scans. Results: Motion models were derived and the variations were evaluated according to three criteria: 1) the average root mean square (RMS) difference which measures the absolute difference between the components of the eigenvectors, 2) the dot product between the eigenvectors which measures the angular difference between the eigenvectors in space, and 3) the Euclidean Model Norm (EMN), which is calculated by summing the dot products of an eigenvector with the first three eigenvectors from the reference motion model in quadrature. EMN measures how well an eigenvector can be reconstructed using another motion model derived using a different DIR algorithm. Results showed that comparing to a reference motion model (derived using the Demons algorithm), the eigenvectors of the motion model derived using the iterative optical flow algorithm has smaller RMS, larger dot product, and larger EMN values than those of the motion model derived using Horn-Schunck algorithm. Conclusion: The study showed that motion models vary depending on which DIR algorithms were used to derive them. The choice of a DIR algorithm may affect the accuracy of the resulting model, and it is important to assess the suitability of the algorithm chosen for a particular application.

    2017-05-02

    Purpose The purpose of this article is to share the lessons learned about the role of team sponsors in action-learning teams as part of community-based health leadership development programs. Design/methodology/approach This case study uses program survey results from fellow participants, action learning coaches and team sponsors to understand the value of sponsors to the teams, the roles they most often filled and the challenges they faced as team sponsors. Findings The extent to which the sponsors were perceived as having contributed to the work of the action learning teams varied greatly from team to team. Most sponsors agreed that they were well informed about their role. The roles sponsors most frequently played were to provide the teams with input and support, serve as a liaison to the community and serve as a sounding board, motivator and cheerleader. The most common challenges or barriers team sponsors faced in this role were keeping engaged in the process, adjusting to the role and feeling disconnected from the program. Practical implications This work provides insights for program developers and community foundations who are interested in building the capacity for health leadership by linking community sponsors with emerging leaders engaged in an action learning experience. Originality/value This work begins to fill a gap in the literature. The role of team sponsors has been studied for single organization work teams but there is a void of understanding about the role of sponsors with multi-organizational teams working to improve health while also learning about leadership.

    Full Text Available The present study analyses the mean and seasonal mesoscale surface circulation of the Northern South China Sea (NSCS and determines the influence of El Niño/SouthernNiño/Southern Oscillation (ENSO. High resolution Eulerian velocity field is derived by combining the available satellite tracked surface drifter data with satellite altimetry during 1993 - 2012. The wind driven current is computed employing the weekly ocean surface mean wind fields derived from the scatterometers on board ERS 1/2, QuikSCAT and ASCAT. The derived mean velocity field exhibits strong boundary currents and broad zonal flow across NSCS. The anomalous field is quite strong in the southern part and the Seasonal circulation clearly depicts the monsoonal forcing. Eddy Kinetic Energy (EKE distribution and its spatial and temporal structures are determined employing Empirical Orthogonal Function (EOF analysis. The ENSO influence on NSCS surface circulation has been analyzed using monthly absolute geostrophic velocity fields during 1996 - 1999.

    This study combined measurements from the Chinese operational geostationary satellite Fengyun-2E (FY-2E) and ground-based weather radars to conduct a statistical survey of isolated convection initiation (CI) over central eastern China (CEC). The convective environment in CEC is modulated by the complex topography and monsoon climate. From May to August 2010, a total of 1,630 isolated CI signals were derived from FY-2E using a semiautomated method. The formation of these satellite-derived CI signals peaks in the early afternoon and occurs with high frequency in areas with remarkable terrain inhomogeneity (e.g., mountain, water, and mountain-water areas). The high signal frequency areas shift from northwest CEC (dry, high altitude) in early summer to southeast CEC (humid, low altitude) in midsummer along with an increasing monthly mean frequency. The satellite-derived CI signals tend to have longer lead times (the time difference between satellite-derived signal formation and radar-based CI) in the late morning and afternoon than in the early morning and night. During the early morning and night, the distinction between cloud top signatures and background terrestrial radiation becomes less apparent, resulting in delayed identification of the signals and thus short and even negative lead times. A decline in the lead time is observed from May to August, likely due to the increasing cloud growth rate and warm-rain processes. Results show increasing lead times with increasing landscape elevation, likely due to more warm-rain processes over the coastal sea and plain, along with a decreasing cloud growth rate from hill and mountain to the plateau.

    Full Text Available Increasing diffuse nitrate loading of groundwater has long been a major environmental and health concern in China, but little is known about the spatial and temporal variability of nitrate concentrations in groundwater at regional scales. The aim of this study was to assess the spatial distribution and variation of nitrate-nitrogen (NO3−-N concentrations in groundwater. We used groundwater quality monitoring data and soil physical characteristics from 21 agro-ecosystems in China for years 2004 to 2014. The results indicated that NO3−-N concentrations were highly variable in shallow groundwater across the landscape. Over the study period, most of the NO3−-N concentrations were below the World Health Organization permissible limit for drinking water (<10 mg N·L. NO3−-N concentrations in groundwater neither significantly increased nor decreased in most agro-ecosystems, but fluctuated with seasons. In addition, groundwater NO3−-N under purple soil (6.81 mg·L−1 and Aeolian sandy soil (6.02 mg·L−1 were significantly higher (p < 0.05 than that under other soil types, and it was medium-high (4.49 mg·L−1 under aquic cinnamon soil. Elevated nitrate concentrations occurred mainly in oasis agricultural areas of northwestern China, where farmlands with coarse-textured soils use flood irrigation. Therefore, arid and semi-arid areas are expected to sustain high NO3−-N concentrations in groundwater. Mitigation strategies can prevent this problem, and include control of N fertilizer input, balanced fertilization, proper rotation system, adoption of improved irrigation methods, and establishment of environmental policies.

    The multi-decadal variations of wintertime extra-tropical cyclones during the last century are studied using a vorticity-based tracking algorithm applied to the long-term ERA-20C reanalysis from ECMWF. The variability of moderate-to-deep extra-tropical winter cyclones in ERA-20C show three distinct periods. Two at the beginning and at the end of the century (1900-1935 and 1980-2010) present weak or no significant trends in the Northern Hemisphere as a whole and only some regional trends. The period in between (1935-1980) is marked by a significant increase in Northern Hemisphere moderate-to-deep cyclones frequency. During the latter period, polar regions underwent a significant cooling over the whole troposphere that increased and shifted poleward the mid-latitude meridional temperature gradient and the baroclinicity. This is linked to positive-to-negative shifts of the PDO between 1935 and 1957 and of the AMO between 1957 and 1980 which mainly reinforced the storm-track eddy generation in the North Pacific and North Atlantic regions respectively, as seen from baroclinic conversion from mean to eddy potential energy. As a result, both the North Pacific and North Atlantic extra-tropical storms increase in frequency during the two subperiods (1935-1957 and 1957-1980), together with other storm-track quantities such as the high-frequency eddy kinetic energy. In contrast, the first and third periods are characterized by a warming of the polar temperatures. However, as the stronger warming is confined to the lower troposphere, the baroclinicity do not uniformly increase in the whole troposphere. This may explain why the recent rapid increase in polar temperatures has not affected the behaviour of extratropical cyclones very much. Finally, the large magnitude of the positive trend found in moderate-to-deep cyclone frequency during the second period is still questioned as the period is marked by an important increase in the number of assimilated observations. However, the

  14. Variable behavior of iPSCs derived from CML patients for response to TKI and hematopoietic differentiation.

    Full Text Available Chronic myeloid leukemia disease (CML found effective therapy by treating patients with tyrosine kinase inhibitors (TKI, which suppress the BCR-ABL1 oncogene activity. However, the majority of patients achieving remission with TKI still have molecular evidences of disease persistence. Various mechanisms have been proposed to explain the disease persistence and recurrence. One of the hypotheses is that the primitive leukemic stem cells (LSCs can survive in the presence of TKI. Understanding the mechanisms leading to TKI resistance of the LSCs in CML is a critical issue but is limited by availability of cells from patients. We generated induced pluripotent stem cells (iPSCs derived from CD34⁺ blood cells isolated from CML patients (CML-iPSCs as a model for studying LSCs survival in the presence of TKI and the mechanisms supporting TKI resistance. Interestingly, CML-iPSCs resisted to TKI treatment and their survival did not depend on BCR-ABL1, as for primitive LSCs. Induction of hematopoietic differentiation of CML-iPSC clones was reduced compared to normal clones. Hematopoietic progenitors obtained from iPSCs partially recovered TKI sensitivity. Notably, different CML-iPSCs obtained from the same CML patients were heterogeneous, in terms of BCR-ABL1 level and proliferation. Thus, several clones of CML-iPSCs are a powerful model to decipher all the mechanisms leading to LSC survival following TKI therapy and are a promising tool for testing new therapeutic agents.

  15. Identification and verification of hybridoma-derived monoclonal antibody variable region sequences using recombinant DNA technology and mass spectrometry.

    Antibody engineering requires the identification of antigen binding domains or variable regions (VR) unique to each antibody. It is the VR that define the unique antigen binding properties and proper sequence identification is essential for functional evaluation and performance of recombinant antibodies (rAb). This determination can be achieved by sequence analysis of immunoglobulin (Ig) transcripts obtained from a monoclonal antibody (MAb) producing hybridoma and subsequent expression of a rAb. However the polyploidy nature of a hybridoma cell often results in the added expression of aberrant immunoglobulin-like transcripts or even production of anomalous antibodies which can confound production of rAb. An incorrect VR sequence will result in a non-functional rAb and de novo assembly of Ig primary structure without a sequence map is challenging. To address these problems, we have developed a methodology which combines: 1) selective PCR amplification of VR from both the heavy and light chain IgG from hybridoma, 2) molecular cloning and DNA sequence analysis and 3) tandem mass spectrometry (MS/MS) on enzyme digests obtained from the purified IgG. Peptide analysis proceeds by evaluating coverage of the predicted primary protein sequence provided by the initial DNA maps for the VR. This methodology serves to both identify and verify the primary structure of the MAb VR for production as rAb. Published by Elsevier Ltd.

    Introduction Elevated levels of tissue factor positive (TF+) microparticles (MPs) are observed in plasma from a variety of patients with an increased risk of thrombosis. We and others have described the measurement of TF activity in MPs isolated from plasma. The aim of this study was to investigate the effects of pre-analytical and analytical variables on TF activity of MPs isolated from blood of healthy volunteers treated ex vivo with or without bacterial lipopolysaccharide. Materials and Methods We evaluated the following parameters: use of different centrifugation speeds to isolate the MPs; comparison of TF activity of MPs isolated from platelet poor plasma versus platelet free plasma; effect of freeze/thaw on MP TF activity; and comparison of the MP TF activity assay with the measurement of TF protein by ELISA or flow cytometry. Results MPs prepared from platelet poor plasma by centrifugation at 20,000 × g or 100,000 × g for 15 minutes had similar levels of TF activity. However, significantly less TF activity was found in MPs isolated from platelet free plasma compared with platelet poor plasma. Interestingly, freeze/thawing of the plasma showed donor to donor variation in MP TF activity, with a moderate increase in some individuals. Conclusion TF+ MPs can be quantitatively isolated from platelet poor or platelet free plasma by centrifugation at 20,000 × g for 15 minutes. Measurement of MP TF activity in plasma can be used to detect a prothrombotic state in patients with various diseases. PMID:21737126

  17. Temporal and spatial variability of phytoplankton pigment concentrations in the Indian Ocean, derived from the CZCS time series images

    Directory of Open Access Journals (Sweden)

    2005-01-01

    Full Text Available A total of 93 monthly global composite remotely sensed ocean color images from the Coastal Zone Color Scanner (CZCS on board the Nimbus-7 satellite were extracted for the Indian Ocean region (35ºN–55ºS; 30–120ºE to examine the seasonal variations in phytoplankton pigment concentrations, resulting from large-scale changes in physical oceanographic processes. The CZCS data sets were analyzed with the PC-SEAPAK software, and revealed large phytoplankton blooms in the northwest Arabian Sea and off the Somali coast. The blooms were triggered by wind-driven upwelling during the southwest monsoonal months of August and September. In the northern Arabian Sea, phytoplankton blooms, detected from January to March, appeared to be associated with nutrient enhancement resulting from winter convective mixing. In the Bay of Bengal, higher pigment concentrations were confined to the coastal regions but varied only marginally between seasons both in the coastal and offshore regions. Phytoplankton pigment concentrations were consistently low in the open Indian Ocean. Analysis of pigment concentrations extracted from the monthly-accumulated images revealed that the Arabian Sea sustained a greater biomass of phytoplankton compared with any other region of the Indian Ocean. Overall, the coastal regions of the Indian Ocean are richer in phytoplankton pigment than the open Indian Ocean. The number of images in individual areas was highly variable throughout the region due to varying cloud cover.

  18. A simple signaling rule for variable life-adjusted display derived from an equivalent risk-adjusted CUSUM chart.

    The variable life-adjusted display (VLAD) is the first risk-adjusted graphical procedure proposed in the literature for monitoring the performance of a surgeon. It displays the cumulative sum of expected minus observed deaths. It has since become highly popular because the statistic plotted is easy to understand. But it is also easy to misinterpret a surgeon's performance by utilizing the VLAD, potentially leading to grave consequences. The problem of misinterpretation is essentially caused by the variance of the VLAD's statistic that increases with sample size. In order for the VLAD to be truly useful, a simple signaling rule is desperately needed. Various forms of signaling rules have been developed, but they are usually quite complicated. Without signaling rules, making inferences using the VLAD alone is difficult if not misleading. In this paper, we establish an equivalence between a VLAD with V-mask and a risk-adjusted cumulative sum (RA-CUSUM) chart based on the difference between the estimated probability of death and surgical outcome. Average run length analysis based on simulation shows that this particular RA-CUSUM chart has similar performance as compared to the established RA-CUSUM chart based on the log-likelihood ratio statistic obtained by testing the odds ratio of death. We provide a simple design procedure for determining the V-mask parameters based on a resampling approach. Resampling from a real data set ensures that these parameters can be estimated appropriately. Finally, we illustrate the monitoring of a real surgeon's performance using VLAD with V-mask.

    Full Text Available A low-level wind maximum is often found over the oceans near many coasts around the world. These Coastal Low-Level Jets (CLLJs play an important role in the coastal weather and have significant impacts on regional climate and ecology as well as on a number of human activities. The presence of CLLJs is related to various local circumstances such as land-sea temperature contrasts, upwelling, coastal terrain, orientation of the coast, and so on, but also to the large-scale atmospheric dynamics. This makes studies of CLLJs not only interesting but also challenging. In this study, based on ERA-Interim reanalysis data, the global distribution, spatio-temporal structure and the seasonal variability of CLLJs are documented. Seasonal data from 1980 to 2011 are used to identify areas where CLLJs are frequently found in the lowest 2 km, following criteria based on the vertical profiles of wind speed and temperature. The results are analysed to highlight the fundamental aspects and distinctive features of the CLLJs across the globe, including their occurrence rate, jet height, maximum wind speed and horizontal extent. Global maps of CLLJs are constructed for the summer and winter seasons. The west coasts of North America, the Iberian Peninsula, north-western Africa and the south-eastern coast of the Arabian Peninsula make up the Northern Hemispheric CLLJ regions, while the west coasts of South America, Australia, and southern Africa comprise the South Hemispheric equivalents. The existence and characteristics of CLLJs along the southern coast of Oman and the western coast of the Iberian Peninsula regions are also discussed, not fully envisaged before in the context of CLLJs. The highest occurrence of CLLJs is found during the summer in both hemispheres, and the coast of Oman has the globally highest CLLJ frequency, with also the highest maximum wind speeds. The most commonly found CLLJ has a maximum wind speed between 9 and 15 m s−1, and occurs at

    Full Text Available In the Sahel region, moderate to coarse spatial resolution remote sensing time series are used in early warning monitoring systems with the aim of detecting unfavorable crop and pasture conditions and informing stakeholders about impending food security risks. Despite growing evidence that vegetation productivity is directly related to phenology, most approaches to estimate such risks do not explicitly take into account the actual timing of vegetation growth and development. The date of the start of the season (SOS or of the peak canopy density can be assessed by remote sensing techniques in a timely manner during the growing season. However, there is limited knowledge about the relationship between vegetation biomass production and these variables at the regional scale. This study describes the first attempt to increase our understanding of such a relationship through the analysis of phenological variables retrieved from SPOT-VEGETATION time series of the Fraction of Absorbed Photosynthetically Active Radiation (FAPAR. Two key phenological variables (growing season length (GSL; timing of SOS and the maximum value of FAPAR attained during the growing season (Peak are analyzed as potentially related to a proxy of biomass production (CFAPAR, the cumulative value of FAPAR during the growing season. GSL, SOS and Peak all show different spatial patterns of correlation with CFAPAR. In particular, GSL shows a high and positive correlation with CFAPAR over the whole Sahel (mean r = 0.78. The negative correlation between delays in SOS and CFAPAR is stronger (mean r = −0.71 in the southern agricultural band of the Sahel, while the positive correlation between Peak FAPAR and CFAPAR is higher in the northern and more arid grassland region (mean r = 0.75. The consistency of the results and the actual link between remote sensing-derived phenological parameters and biomass production were evaluated using field measurements of aboveground herbaceous biomass

    Full Text Available Sponsorship as a marketing communications tool is well adopted in South Africa across various areas such as sports and entertainment. Although world markets have experienced economic turmoil in the last few years, the sponsorship market may be considered to be thriving as companies use this marketing communication tool as a vehicle to create and maintain relationships. The purpose of this study was to explore which sponsors of the South African National Rugby team are sports consumers aware of as a result of the sponsorship. Literature states that awareness also influences the judgments about brands in the consideration set, even without any brand associations in the consumer’s mind. In low involvement decision; where consumers do not need to search extensively for information in order to make a decision; minimal brand awareness levels may be enough to convince the consumer to make their final choice. The study is exploratory in nature however provides a South African perspective on how effective the sponsorship of the Springbok is with regards to creating awareness of the sponsors among sports consumers. The study made use of a qualitative approach whereby primary data was collected by means of focus groups and naïve sketches. Data collected was analyzed by means of content analysis. The findings suggest that participants were predominantly aware of the key sponsors of the Springboks; these were sponsors who had their branding on the Springbok jersey worn during rugby matches. The factors that participants mentioned to contribute to their awareness of the sponsors were the branding on the Springbok playing jersey as well as television adverts along with other promotional tools. This study urges sponsors to not only rely on the sponsorship initiative to create awareness but rather leverage the sponsorship with tools that are relevant to their target audience. This study contributes to sponsorship literature relating to the effectiveness of

    In order to assess the potential of various marine ecosystems for shellfish aquaculture and to evaluate their carrying capacities, there is a need to clarify the response of exploited species to environmental variations using robust ecophysiological models and available environmental data. For a large range of applications and comparison purposes, a non-specific approach based on 'generic' individual growth models offers many advantages. In this context, we simulated the response of blue mussel ( Mytilus edulis L.) to the spatio-temporal fluctuations of the environment in Mont Saint-Michel Bay (North Brittany) by forcing a generic growth model based on Dynamic Energy Budgets with satellite-derived environmental data (i.e. temperature and food). After a calibration step based on data from mussel growth surveys, the model was applied over nine years on a large area covering the entire bay. These simulations provide an evaluation of the spatio-temporal variability in mussel growth and also show the ability of the DEB model to integrate satellite-derived data and to predict spatial and temporal growth variability of mussels. Observed seasonal, inter-annual and spatial growth variations are well simulated. The large-scale application highlights the strong link between food and mussel growth. The methodology described in this study may be considered as a suitable approach to account for environmental effects (food and temperature variations) on physiological responses (growth and reproduction) of filter feeders in varying environments. Such physiological responses may then be useful for evaluating the suitability of coastal ecosystems for shellfish aquaculture.

    Human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) are in vitro models with the clear advantages of their human origin and suitability for human disease investigations. However, limitations include their incomplete characterization and variability reported in different cell lines and laboratories. The purpose of this study was to investigate in silico ionic mechanisms potentially explaining the phenotypic variability of hiPSC-CMs in long QT syndrome type 3 (LQT3) and their response to antiarrhythmic drugs. Populations of in silico hiPSC-CM models were constructed and calibrated for control (n = 1,463 models) and LQT3 caused by I NaL channelopathy (n = 1,401 models), using experimental recordings for late sodium current (I NaL ) and action potentials (APs). Antiarrhythmic drug therapy was evaluated by simulating mexiletine and ranolazine multichannel effects. As in experiments, LQT3 hiPSC-CMs yield prolonged action potential duration at 90% repolarization (APD 90 ) (+34.3% than controls) and large electrophysiological variability. LQT3 hiPSC-CMs with symptomatic APs showed overexpression of I CaL , I K1 , and I NaL , underexpression of I Kr , and increased sensitivity to both drugs compared to asymptomatic LQT3 models. Simulations showed that both mexiletine and ranolazine corrected APD prolongation in the LQT3 population but also highlighted differences in drug response. Mexiletine stops spontaneous APs in more LQT3 hiPSC-CMs models than ranolazine (784/1,401 vs 53/1,401) due to its stronger action on I Na . In silico simulations demonstrate our ability to recapitulate variability in LQT3 and control hiPSC-CM phenotypes, and the ability of mexiletine and ranolazine to reduce APD prolongation, in agreement with experiments. The in silico models also identify potential ionic mechanisms of phenotypic variability in LQT3 hiPSC-CMs, explaining APD prolongation in symptomatic vs asymptomatic LQT3 hiPSC-CMs. Copyright © 2017 The Authors.

    The lack of human data available to inform evidence-based treatment for illness during pregnancy has led to calls for greater inclusion of pregnant women in research, but the extent of their current representation is poorly characterized. Our objective was to measure the current exclusion of pregnant women from industry-sponsored clinical trials as a baseline for future comparison. We compiled data from studies enrolling women of childbearing potential posted on www.ClinicalTrials.gov between 1 October 2011 and 31 January 2012. The review was limited to open United States-based phase IV interventional studies sponsored by the pharmaceutical industry evaluating treatment of conditions that may be experienced by but are not limited to pregnant women and did not involve a medication classified as potentially teratogenic. If there was no mention of pregnancy in the inclusion or exclusion criteria, we contacted a study representative to confirm that pregnant women could be enrolled. Of 558 qualifying industry-sponsored studies, five (1%) were designed specifically for pregnant women. Of 367 phase IV clinical trials with verified inclusion and exclusion criteria, 348 (95%) excluded pregnant women and 19 (5%) did not. We found the exclusion of pregnant women from industry-sponsored clinical trials to be common practice. Moving beyond reflexive exclusion and developing thoughtful criteria for inclusion of pregnant women in clinical research would likely advance the evidence base to inform treatment decisions during pregnancy and lead to better health outcomes for women and children.

    2010-01-01

    Health care reform efforts in both the Clinton and Obama administrations have attempted to address college and university health. Yet, although the world of health care delivery has almost universally evolved to managed care, school health programs have not. In general, school-sponsored health plans do little to improve access and have adopted…

    The chemokine receptor CXCR7, belonging to the membrane-bound G protein-coupled receptor superfamily, is expressed in several tumor types. Inhibition of CXCR7 with either small molecules or small interference (si)RNA has shown promising therapeutic benefits in several tumor models. With the increased interest and effectiveness of biologicals inhibiting membrane-bound receptors we made use of the "Nanobody platform" to target CXCR7. Previously we showed that Nanobodies, i.e. immunoglobulin single variable domains derived from naturally occurring heavy chain-only camelids antibodies, represent new biological tools to efficiently tackle difficult drug targets such as G protein-coupled receptors. In this study we developed and characterized highly selective and potent Nanobodies against CXCR7. Interestingly, the CXCR7-targeting Nanobodies displayed antagonistic properties in contrast with previously reported CXCR7-targeting agents. Several high affinity CXCR7-specific Nanobodies potently inhibited CXCL12-induced β-arrestin2 recruitment in vitro. A wide variety of tumor biopsies was profiled, showing for the first time high expression of CXCR7 in head and neck cancer. Using a patient-derived CXCR7-expressing head and neck cancer xenograft model in nude mice, tumor growth was inhibited by CXCR7-targeting Nanobody therapy. Mechanistically, CXCR7-targeting Nanobodies did not inhibit cell cycle progression but instead reduced secretion of the angiogenic chemokine CXCL1 from head and neck cancer cells in vitro, thus acting here as inverse agonists, and subsequent angiogenesis in vivo. Hence, with this novel class of CXCR7 inhibitors, we further substantiate the therapeutic relevance of targeting CXCR7 in head and neck cancer.

  3. Generation of a Highly Reactive Chicken-Derived Single-Chain Variable Fragment against Fusarium verticillioides by Phage Display

    Full Text Available Fusarium verticillioides is the primary causal agent of Fusarium ear and kernel rot in maize, producing fumonisin mycotoxins that are toxic to humans and domestic animals. Rapid detection and monitoring of fumonisin-producing fungi are pivotally important for the prevention of mycotoxins from entering into food/feed products. Chicken-derived single-chain variable fragments (scFvs against cell wall-bound proteins from F. verticillioides were isolated from an immunocompetent phage display library. Comparative phage enzyme-linked immunosorbant assays (ELISAs and sequencing analyses identified four different scFv antibodies with high sensitivity. Soluble antibody ELISAs identified two highly sensitive scFv antibodies, FvCA3 and FvCA4, with the latter being slightly more sensitive. Three-dimensional modeling revealed that the FvCA4 may hold a better overall structure with CDRH3, CDRL1 and CDRL3 centered in the core region of antibody surface compared with that of other scFvs. Immunofluorescence labeling revealed that the binding of FvCA4 antibody was localized to the cell walls of conidiospores and hyphae of F. verticillioides, confirming the specificity of this antibody for a surface target. This scFv antibody was able to detect the fungal mycelium as low as 10−2 μg/mL and contaminating mycelium at a quantity of 10−2 mg/g maize. This is the first report that scFv antibodies derived from phage display have a wide application for rapid and accurate detection and monitoring of fumonisin-producing pathogens in agricultural samples.

    The nature, variability, and extent of early warning clinical practice alerts derived from automated query of electronic health records (e-alerts) currently used in acute care settings for clinical care or research is unknown. To describe e-alerts in current use in acute care settings at medical centers participating in a nationwide critical care research network. We surveyed investigators at 38 institutions involved in the National Institutes of Health-funded Clinical Trials Network for the Prevention and Early Treatment of Acute Lung Injury (PETAL) for quantitative and qualitative analysis. Thirty sites completed the survey (79% response rate). All sites used electronic health record systems. Epic Systems was used at 56% of sites; the others used alternate commercially available vendors or homegrown systems. Respondents at 57% of sites represented in this survey used e-alerts. All but 1 of these 17 sites used an e-alert for early detection of sepsis-related syndromes, and 35% used an e-alert for pneumonia. E-alerts were triggered by abnormal laboratory values (37%), vital signs (37%), or radiology reports (15%) and were used about equally for clinical decision support and research. Only 59% of sites with e-alerts have evaluated them either for accuracy or for validity. A majority of the research network sites participating in this survey use e-alerts for early notification of potential threats to hospitalized patients; however, there was significant variability in the nature of e-alerts between institutions. Use of one common electronic health record vendor at more than half of the participating sites suggests that it may be possible to standardize e-alerts across multiple sites in research networks, particularly among sites using the same medical record platform.

    Purpose: 2- and 3-dimensional evaluation of quantitative pharmacokinetic parameters derived from the Tofts model modeling dynamic contrast enhancement of lesions in MR mammography. Materials and methods: In 95 patients, MR mammography revealed 127 suspicious lesions. The initial rate of enhancement was coded by color intensity, the post-initial enhancement change is coded by color hue. 2D and 3D analysis of distribution of color hue and intensity, vascular permeability and extracellular volume were performed. Results: In 2D, malignant lesions showed significant higher number of bright red, medium red, dark red, bright green, medium green, dark green and bright blue pixels than benign lesions. In 3D, statistical significant differences between malignant and benign lesions was found for all this parameters. Vascular permeability was significant higher in malignant lesions than in benign lesions. Regression model using the 3D data found that the best discriminator between malignant and benign lesions was combined number of voxels and medium green pixels, with a sensitivity of 79.4% and a specificity of 83.1%. Conclusions: Quantitative analysis of pharmacokinetic variables of contrast kinetics showed significant differences between malignant and benign lesions. 3D analysis showed superior diagnostic differentiation between malignant and benign lesions than 2D analysis. The parametric analysis using a pharmacokinetic model allows objective analysis of contrast enhancement in breast lesions

    The astronomical theory of climate has revolutionized our understanding of past climate change and the development of highly accurate geologic time scales for the entire Cenozoic. Most of this understanding has come from the construction of astronomically tuned global ocean benthic foraminiferal oxygen isotope (δ18O) stacked record, derived by the international drilling operations of DSDP, ODP and IODP. The tuning includes fixed phase relationships between the obliquity and precession cycles and the inferred high-latitude climate, i.e. glacial-interglacial, response, which hark back to SPECMAP, using simple ice sheet models and a limited number of radiometric dates. This approach was largely implemented in the widely applied LR04 stack, though LR04 assumed shorter response times for the smaller ice caps during the Pliocene. In the past decades, an astronomically calibrated time scale for the Pliocene and Pleistocene of the Mediterranean has been developed, which has become the reference for the standard Geologic Time Scale. Typical of the Mediterranean marine sediments are the cyclic lithological alternations, reflecting the interference between obliquity and precession-paced low latitude climate variability, such as the African monsoon. Here we present the first benthic foraminiferal based oxygen isotope record of the Mediterranean reference scale, which strikingly mirrors the LR04. We will use this record to discuss the assumed open ocean glacial-interglacial related phase relations over the past 5.3 million years.

    To evaluate biopharmaceutical industry-sponsored clinical trials placed in countries previously described as emerging regions for clinical research, and potential differences for those placed in Brazil. Data regarding recruitment of subjects for clinical trials were retrieved from www.clinicaltrials.gov on February 2nd 2009. Proportions of sites in each country were compared among emerging countries. Multiple logistic regressions were performed to evaluate whether trial placement in Brazil could be predicted by trial location in other countries and/or by trial features. A total of 8,501 trials were then active and 1,170 (13.8%) included sites in emerging countries (i.e., Argentina, Brazil, China, Czech Republic, Hungary, India, Mexico, Poland, Russia, South Korea, and South Africa). South Korea and China presented a significantly higher proportion of sites when compared to other countries (pattractiveness for biopharmaceutical industry-sponsored clinical trials.

  9. On a State-Sponsored Sport System in China.

    Science.gov (United States)

    Cao, Jie; Zhiwei, Pan

    The gold medal success of China in recent Olympic Games can be traced to the advancement of the state-sponsored sport system (SSSS). While the program was developed initially through socialist ideals, it is more than a centralized government system to monopolize resources for glorified sport performance. Participation in competition is an inherent part of the human condition. Success in athletics is associated with national identity and has economic, social, and cultural implications. Because of this, it is essential that the SSSS adjust and improve to keep pace with other facets of China's quickly changing national reform. In association with emerging economic reform, some sports now receive equal or more funds from private investments compared to government allocation. The state-sponsored sport system must continue to adapt to maintain the Chinese tradition of excellence in competition.

  10. Laboratory incubation experiments assessing the factor interactions affecting urine-derived nitrous oxide emissions from spatially and temporally variable upland pastures

    Urine patches deposited to soils by grazing animals represent hot-spots of nitrous oxide (N2O) emissions (Hargreaves et al., 2015), a powerful greenhouse gas (GHG) and precursor of ozone depletion in the stratosphere. Urine N2O emissions are produced via nitrification of ureolysis-derived ammonium (NH4+) and/or subsequent nitrite (NO2-) and nitrate (NO3-) denitrification (Kool et al., 2006). The dominant process and the N2O fluxes generated depend on interactions between urine characteristics (e.g. nitrogen [N] concentration and volume), soil characteristics (e.g. carbon [C] availability and pH) and preceding and prevailing environmental conditions (e.g. soil moisture and temperature; Bergstermann et al., 2011; Butterbach-Bahl et al., 2013; Dijkstra et al., 2013). The spatial and temporal variability of these interactions in grazing systems is potentially large and greatly increases the uncertainty associated with N2O emission estimates from such systems. In particular, the contribution of extensively managed upland agroecosystems, which occupy ca. 5.5 million hectares in the UK and provide the bulk of land for sheep farming (Pollott & Stone, 2004), to UK GHG emissions is poorly defined. Improving understanding of the interactions between the wide range of factors affecting urine-derived N2O production and emission from pasture soils and considering this in the context of the spatial and temporal variability of the grazing environment could therefore be extremely valuable in improving the accuracy of N2O emission estimates from such systems. The factorial laboratory incubation experiments presented have been designed to assess the interactive effects of factors such as urine N concentration, volume and soil moisture affecting soil N2O (and nitric oxide [NO], nitrogen gas [N2] and carbon dioxide [CO2]) production and emissions (García-Marco et al., 2014) using the state-of-the-art Denitrification Incubation System (DENIS). This work forms part of a wider project

    2013-08-08

    This paper aims at exploring the potential of visible and near infrared (vis-NIR) spectroscopy for on-line measurement of soil pH, with the intention to produce variable rate lime recommendation maps. An on-line vis-NIR soil sensor set up to a frame was used in this study. Lime application maps, based on pH predicted by vis-NIR techniques, were compared with maps based on traditional lab-measured pH. The validation of the calibration model using off-line spectra provided excellent prediction accuracy of pH (R2 = 0.85, RMSEP = 0.18 and RPD = 2.52), as compared to very good accuracy obtained with the on-line measured spectra (R2 = 0.81, RMSEP = 0.20 and RPD = 2.14). On-line predicted pH of all points (e.g., 2,160) resulted in the largest overall field virtual lime requirement (1.404 t), as compared to those obtained with 16 validation points off-line prediction (0.28 t), on-line prediction (0.14 t) and laboratory reference measurement (0.48 t). The conclusion is that the vis-NIR spectroscopy can be successfully used for the prediction of soil pH and for deriving lime recommendations. The advantage of the on-line sensor over sampling with limited number of samples is that more detailed information about pH can be obtained, which is the reason for a higher but precise calculated lime recommendation rate.

    Providers can sponsor their own HMOs in one of three ways: by creating their own HMO, by joint venturing with an existing HMO, or by purchasing an existing HMO. When selecting the best option, providers must consider various market conditions. Managed care penetration in the area, potential competitive responses of existing HMOs, market demand, provider reputation, and provider marketing ability will all influence the feasibility of each option. Providers also must examine their own organizational identity, their ability to raise the necessary capital to start an HMO, their managed care expertise and risk contracting experience, and their information systems capabilities.

    Aboveground biomass estimation (AGB) is essential in determining the environmental and economic values of mangrove forests. Biomass prediction models can be developed through integration of remote sensing, field data and statistical models. This study aims to assess and compare the biomass predictor potential of multispectral bands, vegetation indices and biophysical variables that can be derived from three optical satellite systems: the Sentinel-2 with 10 m, 20 m and 60 m resolution; RapidEye with 5m resolution and PlanetScope with 3m ground resolution. Field data for biomass were collected from a Rhizophoraceae-dominated mangrove forest in Masinloc, Zambales, Philippines where 30 test plots (1.2 ha) and 5 validation plots (0.2 ha) were established. Prior to the generation of indices, images from the three satellite systems were pre-processed using atmospheric correction tools in SNAP (Sentinel-2), ENVI (RapidEye) and python (PlanetScope). The major predictor bands tested are Blue, Green and Red, which are present in the three systems; and Red-edge band from Sentinel-2 and Rapideye. The tested vegetation index predictors are Normalized Differenced Vegetation Index (NDVI), Soil-adjusted Vegetation Index (SAVI), Green-NDVI (GNDVI), Simple Ratio (SR), and Red-edge Simple Ratio (SRre). The study generated prediction models through conventional linear regression and multivariate regression. Higher coefficient of determination (r2) values were obtained using multispectral band predictors for Sentinel-2 (r2 = 0.89) and Planetscope (r2 = 0.80); and vegetation indices for RapidEye (r2 = 0.92). Multivariate Adaptive Regression Spline (MARS) models performed better than the linear regression models with r2 ranging from 0.62 to 0.92. Based on the r2 and root-mean-square errors (RMSE's), the best biomass prediction model per satellite were chosen and maps were generated. The accuracy of predicted biomass maps were high for both Sentinel-2 (r2 = 0

    Tort reform may affect health insurance premiums both by reducing medical malpractice premiums and by reducing the extent of defensive medicine. The objective of this study is to estimate the effects of noneconomic damage caps on the premiums for employer-sponsored health insurance. Employer premium data and plan/establishment characteristics were obtained from the 1999 through 2004 Kaiser/HRET Employer Health Insurance Surveys. Damage caps were obtained and dated based on state annotated codes, statutes, and judicial decisions. Fixed effects regression models were run to estimate the effects of the size of inflation-adjusted damage caps on the weighted average single premiums. State tort reform laws were identified using Westlaw, LEXIS, and statutory compilations. Legislative repeal and amendment of statutes and court decisions resulting in the overturning or repealing state statutes were also identified using LEXIS. Using a variety of empirical specifications, there was no statistically significant evidence that noneconomic damage caps exerted any meaningful influence on the cost of employer-sponsored health insurance. The findings suggest that tort reforms have not translated into insurance savings.

Methods Sports clubs known to have food sponsors and representing the most popular sports for Australian children across a range of demographic areas were recruited. Interview-based questionnaires were conducted at clubs with children aged 10-14 years (n = 103 to examine their recall of local sports club and elite sport sponsors, and their attitudes towards sponsors and sponsorship activities. Results Most children (68% could recall sponsors of their sports club, naming a median of two sponsors, including a median of one food company sponsor each. Almost half (47% of children could recall any sponsors of their favourite elite sporting team. Children aged 10-11 years were more likely than older children to report that they thought about sponsors when buying something to eat or drink (P Conclusions Children's high recall of food and beverage company sport sponsors and their positive attitudes towards these sponsors and their promotions is concerning as this is likely to be linked to children's food preferences and consumption. Limiting children's exposure to this marketing is an important initiative to improve children's nutrition.

    Full Text Available Swarnajayanti Gram Swarozgar Yojana (SGSY is a government-sponsored microfinance program. The scheme is based on four features: group lending with joint liability, progressive lending, back-ended subsidy, and social capital. We propose a new model of SGSY having these features: group lending with individual liability, progressive lending, back-ended subsidy, and social capital. “Joint liability” clause of the existing model is replaced with individual liability in the new model. The paper shows that problem of adverse selection is removed in both models, i.e. in “SGSY with group lending and joint liability” and “SGSY with group lending and individual liability.” The problem of “moral hazard” is more severe in the existing model of SGSY compared with the proposed model of SGSY. Borrowers are also benefitted from participation in the proposed scheme of SGSY than that in the existing model of SGSY.

    On January 12 to 14, 1977, Oak Ridge National Laboratory (ORNL) sponsored a Radwaste Management Workshop in New Orleans, Louisiana, the object of which was to obtain operating data on the uses of evaporation, ion exchange, filtration, and on solid radwaste practices at nuclear power plants. The collected data are being used to update three earlier generic reports done by ORNL on the status of evaporation, ion exchange, and solid radwaste practices at nuclear power plants and to prepare a new one on filtration. All segments of the nuclear power industry were invited to participate, and a total of 188 representatives came. There were four major Workshop groups: volume reduction, solidification, physical and chemical separations, and corrosion. The major findings of each group are reported

  14. Employer-sponsored health insurance and the gender wage gap.

    During prime working years, women have higher expected healthcare expenses than men. However, employees' insurance rates are not gender-rated in the employer-sponsored health insurance (ESI) market. Thus, women may experience lower wages in equilibrium from employers who offer health insurance to their employees. We show that female employees suffer a larger wage gap relative to men when they hold ESI: our results suggest this accounts for roughly 10% of the overall gender wage gap. For a full-time worker, this pay gap due to ESI is on the order of the expected difference in healthcare expenses between women and men. Copyright © 2015 Elsevier B.V. All rights reserved.

    The aim of this study was to assess the performance of health plans sponsored by provider organizations, with respect to plans generating strong positive cash flow relative to plans generating weaker cash flow. A secondary aim was to assess their capital adequacy. The study identified 24 provider-sponsored health plans (PSHPs) with an average positive cash flow margin from 2011 through 2013 at or above the top 75th percentile, defined as "strong cash flow PSHPs:" This group was compared with 72 PSHPs below the 75th percentile, defined as "weak cash flow PSHPs:" Atlantic Information Services Directory of Health Plans was used to identify the PSHPs. Financial ratios were computed from 2013 National Association of Insurance Commissioners Financial Filings. The study conducted a t test mean comparison between strong and weak cash flow PSHPs across an array of financial performance and capital adequacy measures. In 2013, the strong cash flow PSHPs averaged a cash-flow margin ratio of 6.6%. Weak cash flow PSHPs averaged a cash-flow margin of -0.4%. The net worth capital position of both groups was more than 4.5 times authorized capital. The operational analysis shows that strong cash-flow margin PSHPs are managing their medical costs to achieve this position. Although their medical loss ratio increased by almost 300 basis points from 2011 to 2013, it was still statistically significantly lower than the weaker cash flow PSHP group (P<.001). In terms of capital adequacy, both strong and weak cash-flow margin PSHP groups possessed sufficient capital to ensure the viability of these plans.

  17. Can the ministry collaborate to form the "next generation" of sponsors?

    Science.gov (United States)

    Stanley, Teresa

    2007-01-01

    In looking to the future of sponsored ministry of Catholic institutions, the formation of future sponsors--both religious and lay alike--is an important issue. As this ministry continues to evolve, and sponsoring groups determine how best to prepare new sponsors, might it not be time to think about how to pool the ministry's collective wisdom on formation? Sponsors act not only in the name of the health care institution (or other ministry) but on behalf of the faith community engaged in continuing the compassionate healing ministry of Jesus. In Catholic ministry, and particularly health care ministry, sponsors carry out their responsibilities through a multiplicity of organizational relationships. Just as structures differ, so too do criteria that guide who will be called to join a sponsoring group. There are several core elements that are incorporated in the majority of sponsor competency sets. Elements identified by a committee of ministry members, and reviewed by hundreds of sponsors and other ministry leaders are: mission oriented, animated, theologically grounded, collaborative, church related, and accountable. If one is looking at the potential for convening dialogues about possible areas of collaboration in formation, these core elements, with examples of how they are lived out, may offer an outline of areas new sponsors might need to learn more about for their personal and professional development. Our Catholic health ministry depends on leaders who can create and steward organizational cultures that incarnate Jesus' healing. The possibilities for collaboration in the formation of future sponsors are endless, but there are challenges. If you are a member of a sponsor body/council/corporate member in Catholic health care, and are interested in nominating potential persons to take part in a representative group that would discuss possibilities for collaboration in sponsor formation, please go to www.chausa.org/sponsorformation and complete all sections of the

  19. Making renewable energy competitive in India: Reducing financing costs via a government-sponsored hedging facility

    International Nuclear Information System (INIS)

    Farooquee, Arsalan Ali; Shrimali, Gireesh

    2016-01-01

    In India, a significant barrier to market-competitiveness of renewable energy is a shortage of attractive debt. Domestic debt has high cost, short tenors, and variable interest rates, adding 30% to the cost of renewable energy compared to renewable energy projects elsewhere. Foreign debt is as expensive as domestic debt because it requires costly market-based currency hedging solutions. We investigate a government-sponsored foreign exchange facility as an alternative to reducing hedging costs. Using the geometric Brownian motion (GBM) as a representative stochastic model of the INR–USD foreign exchange rate, we find that the expected cost of providing a currency hedge via this facility is 3.5 percentage points, 50% lower than market. This leads to an up to 9% reduction in the per unit cost of renewable energy. However, this requires the government to manage the risks related to unexpected currency movements appropriately. One option to manage these risks is via a capital buffer; for the facility to obtain India's sovereign rating, the capital buffer would need to be almost 30% of the underlying loan. Our findings have significant policy implications given that the Indian government can use this facility to make renewable energy more competitive and, therefore, hasten its deployment. - Highlights: • We analyze a government-sponsored foreign exchange facility in India. •We use geometric Brownian motion to represent the INR–USD exchange rate. •This facility can reduce the currency hedging costs by 50%. •This facility can reduce the levelized cost of renewable energy by 9%. •The capital buffer to reach India's sovereign rating is 30% of the original loan.

    Breon, Richard C

    2016-01-01

    Healthcare's movement to value-based care is causing health systems across the country to consider whether owning or partnering with a health plan could benefit their organizations. Although organizations have different reasons for wanting to enter the insurance business, potential benefits include improving care quality, lowering costs, managing population health, expanding geographic reach, and diversifying the organization's revenue stream. However, the challenges and risks of owning a health plan are formidable: Assuming 100 percent financial risk for a patient population requires considerable financial resources, as well as competencies that are wholly different from those needed to run a hospital or physician group. For Spectrum Health, an integrated, not-for-profit health system based in Grand Rapids, Michigan, owning a health plan has been vital to fulfilling its mission of improving the health of the communities it serves, as well as its value proposition of providing highquality care at lower costs. This article weighs the pros and cons of operating a health plan; explores key business factors and required competencies that organizations need to consider when deciding whether to buy, build, or partner; examines the current environment for provider-sponsored health plans; and shares some of the lessons Spectrum Health has learned over three decades of running its health plan, Priority Health.

  4. Strategic Bidding Behaviors in Nondecreasing Sponsored Search Auctions

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available To realize the specific results in the sponsored search auctions, most advertisers submit particular bid prices. The bidding behaviors with specific purposes are called as the strategic bidding. However, some strategic bidding behaviors will result in negative effects, such as the elimination of the equilibrium and the payment increase for some advertisers. The bidding behaviors with negative results are termed as the vindictive bidding. We survey four strategic bidding behaviors which include a rational bidding and three vindictive bidding strategies. In this paper, we study the relationship between the effects resulted by the vindictive bidding and the valuations of the vindictive advertisers. In our experiments, the search engine provider (SEP is benefited by all vindictive bidding behaviors, and the increment of the SEP's revenue is proportional to the degree of the vindictiveness. Bidding vindictively without sacrificing the own utility improves the advertiser's utility with high probability. Moreover, we observe that the SEP's revenue is improved by the following situations. First, the vindictive advertiser with low valuation in the keywords with high market value results in more SEP's revenue than that in the keywords with low market value. The second case is to raise the bidding competition between advertisers.

    During the last several decades, the scientific and ethics communities have addressed important ethical issues in medical research, resulting in the elaboration and adoption of concepts, guidelines, and codes. Ethical issues in the conduct of Multiregional Clinical Trials have attracted significant attention mainly in the last two decades. With the globalization of clinical research and the rapid expansion to countries with a limited tradition of biomedical research, sponsors must proactively address local ethical issues, the adequacy of oversight as well as the applicability and validity of data, and scientific conclusions drawn from diverse patient populations. This paper highlights some core ethical principles and milestones in medical research, and, from an industry perspective, it discusses ethical issues that the clinical trial team may face when conducting Multiregional Clinical Trials (MRCT, clinical trials conducted at sites located across multiple geographic regions of the world). This paper further highlights the areas of consensus and controversies and proposes points to consider. Copyright © 2010 John Wiley & Sons, Ltd.

  6. Who foregoes survivor protection in employer-sponsored pension annuities?

    Science.gov (United States)

    Johnson, Richard W; Uccello, Cori E; Goldwyn, Joshua H

    2005-02-01

    Retirees in traditional pension plans must generally choose between single life annuities, which provide regular payments until death, and joint and survivor annuities, which pay less each month but continue to make payments to the spouse after the death of the retired worker. This article examines the payout decision and measures the share of married retirees with pension annuities who forego survivor protection. The analysis consists of a probit model of the pension payout decision, based on data from the 1992-2000 waves of the Health and Retirement Study. More than one quarter (28%) of married men and two thirds of married women receiving employer-sponsored retirement annuities declined survivor protection. Men with small pensions and limited household wealth, men in better health than their spouses, and men whose spouses have pension coverage from their own employers are more likely than other men to reject survivor protection. Most workers appear to make payout decisions by rationally balancing the costs and benefits of each type of annuity, suggesting that existing measures to encourage joint and survivor annuities are adequate. However, the growth in 401(k) plans, which are generally not covered by existing laws protecting spousal pension rights, may leave widows vulnerable.

    2016-12-01

    Full Text Available Our objective was to model the average wood density in black spruce trees in representative stands across a boreal forest landscape based on relationships with predictor variables extracted from airborne light detection and ranging (LiDAR point cloud data. Increment core samples were collected from dominant or co-dominant black spruce trees in a network of 400 m2 plots distributed among forest stands representing the full range of species composition and stand development across a 1,231,707 ha forest management unit in northeastern Ontario, Canada. Wood quality data were generated from optical microscopy, image analysis, X-ray densitometry and diffractometry as employed in SilviScan™. Each increment core was associated with a set of field measurements at the plot level as well as a suite of LiDAR-derived variables calculated on a 20 × 20 m raster from a wall-to-wall coverage at a resolution of ~1 point m−2. We used a multiple linear regression approach to identify important predictor variables and describe relationships between stand structure and wood density for average black spruce trees in the stands we observed. A hierarchical classification model was then fitted using random forests to make spatial predictions of mean wood density for average trees in black spruce stands. The model explained 39 percent of the variance in the response variable, with an estimated root mean square error of 38.8 (kg·m−3. Among the predictor variables, P20 (second decile LiDAR height in m and quadratic mean diameter were most important. Other predictors describing canopy depth and cover were of secondary importance and differed according to the modeling approach. LiDAR-derived variables appear to capture differences in stand structure that reflect different constraints on growth rates, determining the proportion of thin-walled earlywood cells in black spruce stems, and ultimately influencing the pattern of variation in important wood quality attributes

    We propose a new methodology for the numerical solution of the isothermal Navier–Stokes–Korteweg equations. Our methodology is based on a semi-discrete Galerkin method invoking functional entropy variables, a generalization of classical entropy variables, and a new time integration scheme. We show that the resulting fully discrete scheme is unconditionally stable-in-energy, second-order time-accurate, and mass-conservative. We utilize isogeometric analysis for spatial discretization and verify the aforementioned properties by adopting the method of manufactured solutions and comparing coarse mesh solutions with overkill solutions. Various problems are simulated to show the capability of the method. Our methodology provides a means of constructing unconditionally stable numerical schemes for nonlinear non-convex hyperbolic systems of conservation laws.

    2017-12-01

    Full Text Available Biogenic emission algorithms predict that oak forests account for ∼ 70 % of the total European isoprene budget. Yet the isoprene emission potentials (IEPs that underpin these model estimates are calculated from a very limited number of leaf-level observations and hence are highly uncertain. Increasingly, micrometeorological techniques such as eddy covariance are used to measure whole-canopy fluxes directly, from which isoprene emission potentials can be calculated. Here, we review five observational datasets of isoprene fluxes from a range of oak forests in the UK, Italy and France. We outline procedures to correct the measured net fluxes for losses from deposition and chemical flux divergence, which were found to be on the order of 5–8 and 4–5 %, respectively. The corrected observational data were used to derive isoprene emission potentials at each site in a two-step process. Firstly, six commonly used emission algorithms were inverted to back out time series of isoprene emission potential, and then an average isoprene emission potential was calculated for each site with an associated uncertainty. We used these data to assess how the derived emission potentials change depending upon the specific emission algorithm used and, importantly, on the particular approach adopted to derive an average site-specific emission potential. Our results show that isoprene emission potentials can vary by up to a factor of 4 depending on the specific algorithm used and whether or not it is used in a big-leaf or canopy environment (CE model format. When using the same algorithm, the calculated average isoprene emission potential was found to vary by as much as 34 % depending on how the average was derived. Using a consistent approach with version 2.1 of the Model for Emissions of Gases and Aerosols from Nature (MEGAN, we derive new ecosystem-scale isoprene emission potentials for the five measurement sites: Alice Holt, UK (10 500 ± 2500

    1999-01-01

    This paper proposes the creation of a corporate sponsored ``Lecture from Space'' program on board the International Space Station (ISS) with funding coming from a host of new technology and marketing spin-offs. This program would meld existing education initiatives in NASA with new corporate marketing techniques. Astronauts in residence on board the ISS would conduct short ten to fifteen minute live presentations and/or conduct interactive discussions carried out by a teacher in the classroom. This concept is similar to a program already carried out during the Neurolab mission on Shuttle flight STS-90. Building on that concept, the interactive simulcasts would be broadcast over the Internet and linked directly to computers and televisions in classrooms worldwide. In addition to the live broadcasts, educational programs and demonstrations can be recorded in space, and marketed and sold for inclusion in television programs, computer software, and other forms of media. Programs can be distributed directly into classrooms as an additional presentation supplement, as well as over the Internet or through cable and broadcast television, similar to the Canadian Discovery Channel's broadcasts of the Neurolab mission. Successful marketing and advertisement can eventually lead to the creation of an entirely new, privately run cottage industry involving the distribution and sale of educationally related material associated with the ISS that would have the potential to become truly global in scope. By targeting areas of expertise and research interest in microgravity, a large curriculum could be developed using space exploration as a unifying theme. Expansion of this concept could enhance objectives already initiated through the International Space University to include elementary and secondary school students. The ultimate goal would be to stimulate interest in space and space related sciences in today's youth through creative educational marketing initiatives while at the

    The Global Climate Observing System (GCOS) has specified the need to systematically produce and validate Essential Climate Variables (ECVs). The Committee on Earth Observation Satellites (CEOS) Working Group on Calibration and Validation (WGCV) and in particular its subgroup on Land Product Validation (LPV) is playing a key coordination role leveraging the international expertise required to address actions related to the validation of global land ECVs. The primary objective of the LPV subgroup is to set standards for validation methods and reporting in order to provide traceable and reliable uncertainty estimates for scientists and stakeholders. The Subgroup is comprised of 9 focus areas that encompass 10 land surface variables. The activities of each focus area are coordinated by two international co-leads and currently include leaf area index (LAI) and fraction of absorbed photosynthetically active radiation (FAPAR), vegetation phenology, surface albedo, fire disturbance, snow cover, land cover and land use change, soil moisture, land surface temperature (LST) and emissivity. Recent additions to the focus areas include vegetation indices and biomass. The development of best practice validation protocols is a core activity of CEOS LPV with the objective to standardize the evaluation of land surface products. LPV has identified four validation levels corresponding to increasing spatial and temporal representativeness of reference samples used to perform validation. Best practice validation protocols (1) provide the definition of variables, ancillary information and uncertainty metrics, (2) describe available data sources and methods to establish reference validation datasets with SI traceability, and (3) describe evaluation methods and reporting. An overview on validation best practice components will be presented based on the LAI and LST protocol efforts to date.

    The variability of the water transport through three major straits of the Mediterranean Sea (Gibraltar, Sicily and Corsica) was investigated using a high-resolution model. This model of the Mediterranean circulation was developed in the context of the Mercator project. The region of interest is the western Mediterranean between the Strait of Gibraltar and the Strait of Sicily. The major water masses and the winter convection in the Gulf of Lions were simulated. The model reproduced the meso-scale and large-scale patterns of the circulation in very good agreement with recent observations. The western and the eastern gyres of the Alboran Sea were observed but high interannual variability was noticed. The Algerian Current splits into several branches at the longitude of the Strait of Sicily level, forming the Tyrrhenian branch, and, the Atlantic Ionian Stream and the Atlantic Tunisian Current in the eastern Mediterranean. The North Current retroflexed north of the Balearic Islands and a dome structure was observed in the Gulf of Lions. The cyclonic barotropic Algerian gyre, which was recently observed during the MATER and ELISA experiment, was evidenced in the simulation. From time-series of 10-day mean transport, the three straits presented a high variability at short time-scales. The transport was generally maximum, in April for the Strait of Gibraltar, in November for the Strait of Sicily, and in January for the Strait of Corsica. The amplitudes of the transport through the Straits of Gibraltar (0.11 Sv) and Sicily (0.30 Sv) presented a weaker seasonal variability than that of the Strait of Corsica (0.70 Sv). The study of the relation between transport and wind forcing showed that the transport through the Strait of Gibraltar is dependent on local zonal wind over short time-scales (70%), which was not the case for the other straits (less than 30%). The maximum (minimum) of the transport occurred for an eastward (westward) wind stress in the strait. An interannual

    Understanding interindividual variability in response to dietary polyphenols remains essential to elucidate their effects on cardiometabolic disease development. A meta-analysis of 128 randomized clinical trials was conducted to investigate the effects of berries and red grapes/wine as sources of anthocyanins and of nuts and pomegranate as sources of ellagitannins on a range of cardiometabolic risk biomarkers. The potential influence of various demographic and lifestyle factors on the variability in the response to these products were explored. Both anthocyanin- and ellagitannin-containing products reduced total-cholesterol with nuts and berries yielding more significant effects than pomegranate and grapes. Blood pressure was significantly reduced by the two main sources of anthocyanins, berries and red grapes/wine, whereas waist circumference, LDL-cholesterol, triglycerides, and glucose were most significantly lowered by the ellagitannin-products, particularly nuts. Additionally, we found an indication of a small increase in HDL-cholesterol most significant with nuts and, in flow-mediated dilation by nuts and berries. Most of these effects were detected in obese/overweight people but we found limited or non-evidence in normoweight individuals or of the influence of sex or smoking status. The effects of other factors, i.e., habitual diet, health status or country where the study was conducted, were inconsistent and require further investigation. PMID:29495642

    2008-09-01

    In order to accurately simulate (13)C NMR spectra of hydroxy, polyhydroxy and methoxy substituted flavonoid a quantitative structure-property relationship (QSPR) model, relating atom-based calculated descriptors to (13)C NMR chemical shifts (ppm, TMS=0), is developed. A dataset consisting of 50 flavonoid derivatives was employed for the present analysis. A set of 417 topological, geometrical, and electronic descriptors representing various structural characteristics was calculated and separate multilinear QSPR models were developed between each carbon atom of flavonoid and the calculated descriptors. Genetic algorithm (GA) and multiple linear regression analysis (MLRA) were used to select the descriptors and to generate the correlation models. Analysis of the results revealed a correlation coefficient and root mean square error (RMSE) of 0.994 and 2.53ppm, respectively, for the prediction set.

    Sulfite-oxidizing enzymes from eukaryotes and prokaryotes have five-coordinate distorted square-pyramidal coordination about the molybdenum atom. The paramagnetic Mo(v) state is easily generated, and over the years four distinct CW EPR spectra have been identified, depending upon enzyme source and the reaction conditions, namely high and low pH (hpH and lpH), phosphate inhibited (P i ) and sulfite (or blocked). Extensive studies of these paramagnetic forms of sulfite-oxidizing enzymes using variable frequency pulsed electron spin echo (ESE) spectroscopy, isotopic labeling and density functional theory (DFT) calculations have led to the consensus structures that are described here. Errors in some of the previously proposed structures are corrected.

  8. Partial reactive crystallization of variable CO2-bearing siliceous MORB-eclogite-derived melt in fertile peridotite and genesis of alkalic basalts with signatures of crustal recycling

    Science.gov (United States)

    Mallik, A.; Dasgupta, R.

    2013-12-01

    The presence of heterogeneity in the form of recycled altered oceanic crust (MORB-eclogite) has been proposed in the source of HIMU ocean island basalts (OIBs) [1]. Partial melts of recycled oceanic crust, however, are siliceous and Mg-poor and thus do not resemble the major element compositions of alkalic OIBs that are silica-poor and Mg-rich. In an upwelling heterogenous mantle, MORB-eclogite undergoes melting deeper than volatile-free peridotite, hence, andesitic partial melt derived from eclogite will react with subsolidus peridotite. We have examined the effect of such a melt-rock reaction under volatile-free conditions at 1375 °C, 3 GPa by varying the melt-rock ratio from 8 to 50 wt.% [2]. We concluded that the reacted melts reproduce certain major element characteristics of oceanic basanites, but not nephelinites. Also, the melt-rock reaction produces olivine and garnet-bearing websteritic residue. Because presence of CO2 has been invoked in the source of many HIMU ocean islands, the effect of CO2 on such a melt-rock reaction needs to be evaluated. Accordingly, we performed reaction experiments on mixtures of 25% and 33% CO2-bearing andesitic partial melt and peridotite at 1375 °C, 3 GPa by varying the dissolved CO2 content of the reacting melts from 1 to 5 wt.% (bulk CO2 from 0.25 to 1.6 wt.%) [3, this study]. Owing to melt-rock reaction, with increasing CO2 in the bulk mixture, (a) modes of olivine and cpx decrease while melt, opx and garnet increase, (b) reacted melts evolve to greater degree of Si-undersaturation (from andesite through basanite to nephelinite), (c) enhanced crystallization of garnet take place with higher CO2 in the melt, reducing alumina content of the reacted melts, and (d) CaO and MgO content of the reacted melts increase, without affecting FeO* and Na2O contents (indicating greater propensity of Ca2+ and Mg2+ over Fe2+ and Na+ to enter silicate melt as carbonate). For a given melt-MgO, the CO2-bearing reacted melts are a better

    As a consequence of the so-called ''Heart-Valve-Affair'' in 1994, the German public became aware of the potential criminal significance of industrial sponsoring and third-party financial support in medicine. Since 1997, when the German Anti-Corruption Law came into effect, the penal regulations regarding bribery and benefits for public officers were tightened. Due to the lack of explicit and generally accepted guidelines in combination with regional differences of jurisdiction, there is a lingering uncertainty regarding the criminal aspects of third-party funding and industrial sponsoring. The aim of this review is to summarize the penal and professional implications of third-party funding and sponsoring in medicine including recent aspects of jurisdiction. The currently available recommendations on this issue are introduced. (orig.)

    The Common Rule creates a division of moral labor in research. It implies that investigators and sponsors can outsource their ethical obligations to IRBs and participants, thereby fostering a culture of compliance, rather than one of responsibility. The proposed revisions to the Common Rule are likely to exacerbate this problem. To harness the expressive power of the law, I propose the Common Rule be revised to include the ethical responsibilities of investigators and sponsors. © 2013 American Society of Law, Medicine & Ethics, Inc.

    Mapping the international landscape of clinical trials may inform global health research governance, but no large-scale data are available. Industry or non-industry sponsorship may have a major influence in this mapping. We aimed to map the global landscape of industry- and non-industry-sponsored clinical trials and its evolution over time. We analyzed clinical trials initiated between 2006 and 2013 and registered in the WHO International Clinical Trials Registry Platform (ICTRP). We mapped single-country and international trials by World Bank's income groups and by sponsorship (industry- vs. non- industry), including its evolution over time from 2006 to 2012. We identified clusters of countries that collaborated significantly more than expected in industry- and non-industry-sponsored international trials. 119,679 clinical trials conducted in 177 countries were analysed. The median number of trials per million inhabitants in high-income countries was 100 times that in low-income countries (116.0 vs. 1.1). Industry sponsors were involved in three times more trials per million inhabitants than non-industry sponsors in high-income countries (75.0 vs. 24.5) and in ten times fewer trials in low- income countries (0.08 vs. 1.08). Among industry- and non-industry-sponsored trials, 30.3% and 3.2% were international, respectively. In the industry-sponsored network of collaboration, Eastern European and South American countries collaborated more than expected; in the non-industry-sponsored network, collaboration among Scandinavian countries was overrepresented. Industry-sponsored international trials became more inter-continental with time between 2006 and 2012 (from 54.8% to 67.3%) as compared with non-industry-sponsored trials (from 42.4% to 37.2%).

    several criteria. Using the deployment of the federal funding with industrial participation as a performance criterion, over the course of the program, the copsonsors contributed more dollars than the federal funds. As stated earlier, a little more than half of the funding for the Program was derived from industrial partners. The industrial partners also enthusiastically supported the research and development activities with cash contribution of $4,710,372.67, nearly 65% of the required cost share. Work on all of the tasks proposed under the Cooperative Agreement has been completed. This report summarizes and highlights the results from the Program. Under the Cooperative Agreement Program, energy-related tasks emphasized petroleum processing, upgrading and characterization, coal and biomass beneficiation and upgrading, coal combustion systems development including oxy-combustion, emissions monitoring and abatement, coal gasification technologies including gas clean-up and conditioning, hydrogen and liquid fuels production, and the development of technologies for the utilization of renewable energy resources. Environmental-related activities emphasized cleaning contaminated soils using microbial fuel cells, development of processes and sorbents for emissions reduction and recovery of water from power plant flue gas, and biological carbon capture and reuse. Technology enhancement activities included resource characterization studies, development of improved methods, monitors and sensors. In general the goals of the tasks proposed were to enhance competitiveness of U.S. technology, increase production of domestic resources, and reduce environmental impacts associated with energy production and utilization. Technologies being brought to commercialization as a result of the funds provided by the Cooperative Agreement contribute to the overall goals of the USDOE and the nation. Each has broad applicability both within the United States and abroad, thereby helping to enhance the

    To summarize the present development by analysis of projects in schistosomiasis funded by National Science Foundation of China (NSFC). Based on the ISIS database of NFSC, the projects in the studies of schistosomiasis from 2005 to 2016 were analyzed. The distributions of sponsored numbers, amounts, types, agencies, disciplines and changes in research topics by means of network profiles were described. During the study period, 198 projects were funded by NSFC totally with 76.05 million yuan in which the general and youth projects were main types. The main sponsored agencies were research institutes and medical colleges. The top three fields sponsored were medical pathogenic microbes and infection, veterinary and medical immunology. The funding on schistosomiasis researches has a downward trend, but studies are continuing in depth. In this situation, innovative and interdisciplinary researches need to be encouraged to promote the development of schistosomiasis.

    Philadelphia's Healthy Kids, Healthy Communities Out-of-School Time (OST) Initiative led by the Health Promotion Council developed 10 Healthy Living Guidelines for Out-of-School Time Programs to support a healthy environment for Philadelphia youth in 200 OST programs. Health Promotion Council participated in an enhanced cross-site evaluation with the national Robert Wood Johnson Foundation evaluator during the final year of funding to learn more about food and nutrition in the OST setting, and to share data and engage the OST food providers. A plate waste study measured the quantity and nutrition composition of meals served to youth compared to food not eaten. Staff interviews measured program adherence to the Healthy Living Guidelines, along with other facets of the food environment in 7 Philadelphia OST programs. Online surveys were sent to OST programs. Food providers (sponsors) were interviewed using Appreciative Inquiry methodology to gain insight into systems, goals, and common interests. Aggregated plate waste data from 7 observations showed an average of 42% of the food uneaten after meal/snack consumption, and high sodium content of the meals. Twenty-nine staff at OST programs completed the online survey, and 3 food sponsors were interviewed. Recommendations to improve the food included increasing variety, offering more salads, fruits and vegetables, and culturally appropriate foods. Food sponsor interviews showed a variety of meal production, distribution, service and training systems, and an interest in working together. The food sponsors met to review the data and prioritized common goals. They continue to work together to improve systems and meals for food service. A food sponsors work group formed and continues as a result of sharing enhanced cross-site data about food in OST settings. Food sponsors continue to work together to improve systems and nutritional offerings for Philadelphia OST programs.

This study seeks to explore how staff members consider the impact of sponsors and donors on exhibit content and design. The data collection involves a survey, interviews and a focus group...... interview with staff members, who work with planning and constructing new exhibitions at their science and technology centre. The results suggest that sponsors may interfere in exhibition construction both directly and indirectly. This means that sponsors could put explicit demands when it comes...... to the choice of scientific content and design and thereby interfere directly. Indirect impact, on the other hand, refers to implicit demands of sponsors where staff members take into account for what they believe are views of the sponsors through self-censorship....

    2006-02-01

    To examine whether adolescents' exposure to youth smoking prevention ads sponsored by tobacco companies promotes intentions to smoke, curiosity about smoking, and positive attitudes toward the tobacco industry. A randomised controlled experiment compared adolescents' responses to five smoking prevention ads sponsored by a tobacco company (Philip Morris or Lorillard), or to five smoking prevention ads sponsored by a non-profit organisation (the American Legacy Foundation), or to five ads about preventing drunk driving. A large public high school in California's central valley. A convenience sample of 9th and 10th graders (n = 832) ages 14-17 years. Perceptions of ad effectiveness, intention to smoke, and attitudes toward tobacco companies measured immediately after exposure. As predicted, adolescents rated Philip Morris and Lorillard ads less favourably than the other youth smoking prevention ads. Adolescents' intention to smoke did not differ as a function of ad exposure. However, exposure to Philip Morris and Lorillard ads engendered more favourable attitudes toward tobacco companies. This study demonstrates that industry sponsored anti-smoking ads do more to promote corporate image than to prevent youth smoking. By cultivating public opinion that is more sympathetic toward tobacco companies, the effect of such advertising is likely to be more harmful than helpful to youth.

    To analyze the projects on the infectious disease epidemiology sponsored by the National Natural Science Foundation of China (NSFC), explore the hotspot and development trend, and offer a reference for researchers in this field. Based on the NSFC database, the projects on the infectious disease epidemiology (H2609) sponsored from 1987 to 2014 were analyzed. The changes of fund numbers, amounts and research fields were described. During the study period, NSFC sponsored 373 projects, including 228 general projects (61.1%), 78 youth projects (20.9%) and 67 other projects (18.0%). The average amount of the grant was 358.2 thousand Yuan (20 thousand-8 million). The main sponsored research fields were mechanisms of pathogen and immunity (36.2%) and population-based epidemiological studies (33.0%). The top three diseases were hepatitis, HIV/AIDS and tuberculosis. The amount of funding on researches of infectious disease epidemiology has increased continuously, which has played an important role in training scientific talents in the field of prevention and control of infectious diseases.

  2. The Effect of Massachusetts' Health Reform on Employer-Sponsored Insurance Premiums.

    Science.gov (United States)

    Cogan, John F; Hubbard, R Glenn; Kessler, Daniel

    2010-01-01

    In this paper, we use publicly available data from the Medical Expenditure Panel Survey - Insurance Component (MEPS-IC) to investigate the effect of Massachusetts' health reform plan on employer-sponsored insurance premiums. We tabulate premium growth for private-sector employers in Massachusetts and the United States as a whole for 2004 - 2008. We estimate the effect of the plan as the difference in premium growth between Massachusetts and the United States between 2006 and 2008-that is, before versus after the plan-over and above the difference in premium growth for 2004 to 2006. We find that health reform in Massachusetts increased single-coverage employer-sponsored insurance premiums by about 6 percent, or $262. Although our research design has important limitations, it does suggest that policy makers should be concerned about the consequences of health reform for the cost of private insurance.

  9. Why Consumers Misattribute Sponsorships to Non-Sponsor Brands: Differential Roles of Item and Relational Communications.

    Science.gov (United States)

    Weeks, Clinton S; Humphreys, Michael S; Cornwell, T Bettina

    2018-02-01

    Brands engaged in sponsorship of events commonly have objectives that depend on consumer memory for the sponsor-event relationship (e.g., sponsorship awareness). Consumers however, often misattribute sponsorships to nonsponsor competitor brands, indicating erroneous memory for these relationships. The current research uses an item and relational memory framework to reveal sponsor brands may inadvertently foster this misattribution when they communicate relational linkages to events. Effects can be explained via differential roles of communicating item information (information that supports processing item distinctiveness) versus relational information (information that supports processing relationships among items) in contributing to memory outcomes. Experiment 1 uses event-cued brand recall to show that correct memory retrieval is best supported by communicating relational information when sponsorship relationships are not obvious (low congruence). In contrast, correct retrieval is best supported by communicating item information when relationships are obvious (high congruence). Experiment 2 uses brand-cued event recall to show that, against conventional marketing recommendations, relational information increases misattribution, whereas item information guards against misattribution. Results suggest sponsor brands must distinguish between item and relational communications to enhance correct retrieval and limit misattribution. Methodologically, the work shows that choice of cueing direction is critical in differentially revealing patterns of correct and incorrect retrieval with pair relationships.

    Kaspin, Lisa C; Gorman, Kathleen M; Miller, Ross M

    2013-02-01

    This review determines the characteristics and health-related and economic outcomes of employer-sponsored wellness programs and identifies possible reasons for their success. PubMed, ABI/Inform, and Business Source Premier databases, and Corporate Wellness Magazine were searched. English-language articles published from 2005 to 2011 that reported characteristics of employer-sponsored wellness programs and their impact on health-related and economic outcomes among US employees were accepted. Data were abstracted, synthesized, and interpreted. Twenty references were accepted. Wellness interventions were classified into health assessments, lifestyle management, and behavioral health. Improved economic outcomes were reported (health care costs, return on investment, absenteeism, productivity, workers' compensation, utilization) as well as decreased health risks. Programs associated with favorable outcomes had several characteristics in common. First, the corporate culture encouraged wellness to improve employees' lives, not only to reduce costs. Second, employees and leadership were strongly motivated to support the wellness programs and to improve their health in general. Third, employees were motivated by a participation-friendly corporate policy and physical environment. Fourth, successful programs adapted to the changing needs of the employees. Fifth, community health organizations provided support, education, and treatment. Sixth, successful wellness programs utilized technology to facilitate health risk assessments and wellness education. Improved health-related and economic outcomes were associated with employer-sponsored wellness programs. Companies with successful programs tended to include wellness as part of their corporate culture and supported employee participation in several key ways.

In 1996 it was realized that the attitude magnetometers on-board the Iridium satellites, then in fabrication, could potentially be used to obtain the first ever global and continuous measurements of the Birkeland currents with a sufficiently short re-sampling cadence (10 minutes) to track the dynamic evolution of the large-scale currents. The experience of taking this idea from 1996 through various research grant supported efforts, mission of opportunity proposal attempts, and finally through funding and implementation as a National Science Foundation geospace facility, revealed a number of challenges both in proposing innovative solutions to existing sponsor programs and also in working between the federal sponsor community and the private commercial space environment. Implementing AMPERE required a code change to on-board software on the Iridium satellites and it proved necessary to engage NASA to adjust the solicitation language to allow AMPERE. For NASA proposals we also encountered a conflict with respect to federal sponsorship such that the original business configuration of Iridium could not accept the accounting regime implied by a sub-contract derived from a federal contract acquisition. Subsequent mission of opportunity efforts encountered various other challenges including the cancellation of an explorer to fund the exploration initiative in 2001. The facilities proposal to NSF was almost not submitted owing a funding vehicle disparity between the preferred proposer structure (contract) vs NSF's requirement to fund only grants and a final hurdle concerned the structure of the contract with Iridium which was initially a sub-contract but was changed to a fixed-price data purchase due to NSF's limitations on funding fee-bearing engineering

    Children's thinking is highly variable at every level of analysis, from neural and associative levels to the level of strategies, theories, and other aspects of high-level cognition. This variability exists within people as well as between them; individual children often rely on different strategies or representations on closely related problems…

    The high spatial variability of soils is a relevant issue at local and global scales, and determines the complexity of soil ecosystem functions and services. This variability derives from strong dependencies of soil ecosystems on parent materials, climate, relief and biosphere, including human impact. Although present in all environments, the interactions of soils with these forming factors are particularly striking in mountain areas.

  18. Development, implementation and critique of a bioethics framework for pharmaceutical sponsors of human biomedical research.

    2015-11-01

    Pharmaceutical human biomedical research is a multi-dimensional endeavor that requires collaboration among many parties, including those who sponsor, conduct, participate in, or stand to benefit from the research. Human subjects' protections have been promulgated to ensure that the benefits of such research are accomplished with respect for and minimal risk to individual research participants, and with an overall sense of fairness. Although these protections are foundational to clinical research, most ethics guidance primarily highlights the responsibilities of investigators and ethics review boards. Currently, there is no published resource that comprehensively addresses bioethical responsibilities of industry sponsors; including their responsibilities to parties who are not research participants, but are, nevertheless key stakeholders in the endeavor. To fill this void, in 2010 Eli Lilly and Company instituted a Bioethics Framework for Human Biomedical Research. This paper describes how the framework was developed and implemented and provides a critique based on four years of experience. A companion article provides the actual document used by Eli Lilly and Company to guide ethical decisions regarding all phases of human clinical trials. While many of the concepts presented in this framework are not novel, compiling them in a manner that articulates the ethical responsibilities of a sponsor is novel. By utilizing this type of bioethics framework, we have been able to develop bioethics positions on various topics, provide research ethics consultations, and integrate bioethics into the daily operations of our human biomedical research. We hope that by sharing these companion papers we will stimulate discussion within and outside the biopharmaceutical industry for the benefit of the multiple parties involved in pharmaceutical human biomedical research.

    Using employees' longitudinal data, we study the effect of working hours on the propensity of firms to sponsor training of their employees. We show that, whereas male part-time workers are less likely to receive training than male full-timers, part-time working women are as likely to receive training as full-time working women. Although we cannot rule out gender-working time specific monopsony power, we speculate that the gender-specific effect of working hours on training has to do with gend...

    2005-11-01

    This article describes a university-sponsored home health nursing program in a large urban center in Pakistan and details the essential elements needed in implementing such a program in a developing country. Compared to in-hospital treatment, home healthcare reduced hospital stay from 12.8 days to 3.9 days, and resulted in a net savings of Pakistani rupees (PRs) 5,374,135 (USD 89,569). A cost-effective home treatment program in a resource-limited country can be successfully implemented by using the hospital pharmacy as the central point for the preparation and distribution of medications and specialty nursing services.

    2009-08-01

    We sought to examine the legal and ethical implications of workplace health risk reduction programs (HRRPs) using health risk assessments, individually focused risk reduction, and financial incentives to promote compliance. We conducted a literature review, analyzed relevant statutes and regulations, and considered the effects of these programs on employee health privacy. A variety of laws regulate HRRPs, and there is little evidence that employer-sponsored HRRPs violate these provisions; infringement on individual health privacy is more difficult to assess. Although current laws permit a wide range of employer health promotion activities, HRRPs also may entail largely unquantifiable costs to employee privacy and related interests.

    1993-01-01

    Sports are believed to contribute to physical well-being, social adjustment, and self-esteem. In this study, perceptions of social competence and family dynamics were examined among adolescent participants in school-sponsored and independent sports (baseball and skateboarding). Subjects, aged 12 to 19 years, completed a questionnaire consisting of FACES III, a social competence scale, and miscellaneous items concerning school performance, sports commitment, and perceptions of adult attitudes. Perceptions of social competence were differentially related to degree of sports involvement and perceived skill but were not related to the social acceptability of the sport. Adolescents in both groups depicted their families as demonstrating low levels of cohesion but high adaptability.

    As public utilities and regulators begin to define their new relationship under various forms of regulations, some have questioned the continuing need for commission-sponsored audits. This study evaluates the role of such audits by examining their core purpose: the reduction of information risk (risk that a commission might make a wrong decision because of reliance on faulty information). It identifies five generic types of information that will be needed by commissions in the future and describes a cost-benefit analysis for identifying the appropriate method for mitigating information risk for state regulatory commissions.

    Enrollment of a representative population to cancer clinical trials ensures scientific reliability and generalizability of results. This study evaluated the similarity of patients enrolled in NCI-supported group gynecologic cancer trials to the incident US population. Accrual to NCI-sponsored ovarian, uterine, and cervical cancer treatment trials between 2003 and 2012 were examined. Race, ethnicity, age, and insurance status were compared to the analogous US patient population estimated using adjusted SEER incidence data. There were 18,913 accruals to 156 NCI-sponsored gynecologic cancer treatment trials, ovarian (56%), uterine (32%), and cervical cancers (12%). Ovarian cancer trials included the least racial, ethnic and age diversity. Black women were notably underrepresented in ovarian trials (4% versus 11%). Hispanic patients were underrepresented in ovarian and uterine trials (4% and 5% versus 18% and 19%, respectively), but not in cervical cancer trials (14 versus 11%). Elderly patients were underrepresented in each disease area, with the greatest underrepresentation seen in ovarian cancer patients over the age of 75 (7% versus 29%). Privately insured women were overrepresented among accrued ovarian cancer patients (87% versus 76%), and the uninsured were overrepresented among women with uterine or cervical cancers. These patterns did not change over time. Several notable differences were observed between the patients accrued to NCI funded trials and the incident population. Improving representation of racial and ethnic minorities and elderly patients on cancer clinical trials continues to be a challenge and priority. Copyright © 2016 Elsevier Inc. All rights reserved.

    This updated Good Publication Practice (GPP) guideline, known as GPP3, builds on earlier versions and provides recommendations for individuals and organizations that contribute to the publication of research results sponsored or supported by pharmaceutical, medical device, diagnostics, and biotechnology companies. The recommendations are designed to help individuals and organizations maintain ethical and transparent publication practices and comply with legal and regulatory requirements. These recommendations cover publications in peer-reviewed journals and presentations (oral or poster) at scientific congresses. The International Society for Medical Publication Professionals invited more than 3000 professionals worldwide to apply for a position on the steering committee, or as a reviewer, for this guideline. The GPP2 authors reviewed all applications (n = 241) and assembled an 18-member steering committee that represented 7 countries and a diversity of publication professions and institutions. From the 174 selected reviewers, 94 sent comments on the second draft, which steering committee members incorporated after discussion and consensus. The resulting guideline includes new sections (Principles of Good Publication Practice for Company-Sponsored Medical Research, Data Sharing, Studies That Should Be Published, and Plagiarism), expands guidance on the International Committee of Medical Journal Editors' authorship criteria and common authorship issues, improves clarity on appropriate author payment and reimbursement, and expands information on the role of medical writers. By following good publication practices (including GPP3), individuals and organizations will show integrity; accountability; and responsibility for accurate, complete, and transparent reporting in their publications and presentations.

    2008-10-01

    This study aimed to elicit and compare the responses of Australian consumers towards New Zealand (NZ) direct-to-consumer-advertisements (DTCA) for prescription medicines and matched pharmaceutical company-sponsored advertisements from Australia. A survey questionnaire was mailed to a random sample of residents in a metropolitan area in NSW. Potential participants were randomised to receive one of four different advertisements: two for weight loss and two for Alzheimer's disease. A total of 413 responses were received and analysed. Participants reported that they were not likely to ask for a prescription from their doctor as a result of seeing any of the advertisements in the study. The Australian disease awareness advertisement that did not refer to a medicinal treatment was perceived as more valuable than the NZ DTCA or other Australian advertisement. Overall, participants found it easier to make sense of the more informational advertisements, and felt that there was insufficient information regarding the disease/condition and treatments in the more emotive and transformational advertisements. While there is concern over potential negative effects of pharmaceutical-sponsored disease awareness advertisements, this study found that Australian consumers perceived an informational advertisement with a list of disease symptoms to be valuable. These findings contribute to debate in New Zealand and Australia regarding DTCA and disease awareness advertising, and have the potential to inform guidelines relevant to the advertising of prescription medicine in each country.

  12. The international space station: An opportunity for industry-sponsored global education

    1999-01-01

    The International Space Station provides an excellent opportunity for industry sponsorship of international space education. As a highly visible worldwide asset, the space station already commands our interest. It has captured the imagination of the world's researchers and connected the world's governments. Once operational, it can also be used to capture the dreams of the world's children and connect the world's industry through education. The space station's global heritage and ownership; its complex engineering, construction, and operation; its flexible research and technology demonstration capability; and its long duration make it the perfect educational platform. These things also make a space station education program attractive to industry. Such a program will give private industry the opportunity to sponsor space-related activities even though a particular industry may not have a research or technology-driven need for space utilization. Sponsors will benefit through public relations and goodwill, educational promotions and advertising, and the sale and marketing of related products. There is money to be made by supporting, fostering, and enabling education in space through the International Space Station. This paper will explore various ISS education program and sponsorship options and benefits, will examine early industry response to such an opportunity, and will make the case for moving forward with an ISS education program as a private sector initiative.

  13. Derivative chameleons

    International Nuclear Information System (INIS)

    Noller, Johannes

    2012-01-01

    We consider generalized chameleon models where the conformal coupling between matter and gravitational geometries is not only a function of the chameleon field φ, but also of its derivatives via higher order co-ordinate invariants (such as ∂ μ φ∂ μ φ,□φ,...). Specifically we consider the first such non-trivial conformal factor A(φ,∂ μ φ∂ μ φ). The associated phenomenology is investigated and we show that such theories have a new generic mass-altering mechanism, potentially assisting the generation of a sufficiently large chameleon mass in dense environments. The most general effective potential is derived for such derivative chameleon setups and explicit examples are given. Interestingly this points us to the existence of a purely derivative chameleon protected by a shift symmetry for φ → φ+c. We also discuss potential ghost-like instabilities associated with mass-lifting mechanisms and find another, mass-lowering and instability-free, branch of solutions. This suggests that, barring fine-tuning, stable derivative models are in fact typically anti-chameleons that suppress the field's mass in dense environments. Furthermore we investigate modifications to the thin-shell regime and prove a no-go theorem for chameleon effects in non-conformal geometries of the disformal type

    We consider generalized chameleon models where the conformal coupling between matter and gravitational geometries is not only a function of the chameleon field φ, but also of its derivatives via higher order co-ordinate invariants (such as ∂{sub μ}φ∂{sup μ}φ,□φ,...). Specifically we consider the first such non-trivial conformal factor A(φ,∂{sub μ}φ∂{sup μ}φ). The associated phenomenology is investigated and we show that such theories have a new generic mass-altering mechanism, potentially assisting the generation of a sufficiently large chameleon mass in dense environments.

    Offering a concise but complete survey of the common features of the microstructure of electricity markets, this book describes the state of the art in the different proposed electricity price models for pricing derivatives and in the numerical methods used to price and hedge the most prominent derivatives in electricity markets, namely power plants and swings. The mathematical content of the book has intentionally been made light in order to concentrate on the main subject matter, avoiding fastidious computations. Wherever possible, the models are illustrated by diagrams. The book should allow prospective researchers in the field of electricity derivatives to focus on the actual difficulties associated with the subject. It should also offer a brief but exhaustive overview of the latest techniques used by financial engineers in energy utilities and energy trading desks.

    The Food and Drug Administration's final rule on investigational new drug application safety reporting, effective from 28 March 2011, clarified the reporting requirements for serious and unexpected suspected adverse reactions occurring in clinical trials. The Clinical Trials Transformation Initiative released recommendations in 2013 to assist implementation of the final rule; however, anecdotal reports and data from a Food and Drug Administration audit indicated that a majority of reports being submitted were still uninformative and did not result in actionable changes. Clinical Trials Transformation Initiative investigated remaining barriers and potential solutions to full implementation of the final rule by polling and interviewing investigators, clinical research staff, and sponsors. In an opinion-gathering effort, two discrete online surveys designed to assess challenges and motivations related to management of expedited (7- to 15-day) investigational new drug safety reporting processes in oncology trials were developed and distributed to two populations: investigators/clinical research staff and sponsors. Data were collected for approximately 1 year. Twenty-hour-long interviews were also conducted with Clinical Trials Transformation Initiative-nominated interview participants who were considered as having extensive knowledge of and experience with the topic. Interviewees included 13 principal investigators/study managers/research team members and 7 directors/vice presidents of pharmacovigilance operations from 5 large global pharmaceutical companies. The investigative site's responses indicate that too many individual reports are still being submitted, which are time-consuming to process and provide little value for patient safety assessments or for informing actionable changes. Fewer but higher quality reports would be more useful, and the investigator and staff would benefit from sponsors'"filtering" of reports and increased sponsor communication. Sponsors

    Pregnancy is associated with a significant cost for employers providing health insurance benefits to their employees. The latest study on the topic was published in 2002, estimating the unintended pregnancy rate for women covered by employer-sponsored insurance benefits to be approximately 29%. The primary objective of this study was to update the cost of unintended pregnancy to employer-sponsored health insurance plans with current data. The secondary objective was to develop a regression model to identify the factors and associated magnitude that contribute to unintended pregnancies in the employee benefits population. We developed stepwise multinomial logistic regression models using data from a national survey on maternal attitudes about pregnancy before and shortly after giving birth. The survey was conducted by the Centers for Disease Control and Prevention through mail and via telephone interviews between 2009 and 2011 of women who had had a live birth. The regression models were then applied to a large commercial health claims database from the Truven Health MarketScan to retrospectively assign the probability of pregnancy intention to each delivery. Based on the MarketScan database, we estimate that among employer-sponsored health insurance plans, 28.8% of pregnancies are unintended, which is consistent with national findings of 29% in a survey by the Centers for Disease Control and Prevention. These unintended pregnancies account for 27.4% of the annual delivery costs to employers in the United States, or approximately 1% of the typical employer's health benefits spending for 1 year. Using these findings, we present a regression model that employers could apply to their claims data to identify the risk for unintended pregnancies in their health insurance population. The availability of coverage for contraception without employee cost-sharing, as was required by the Affordable Care Act in 2012, combined with the ability to identify women who are at high

    This analysis uses new questions in the Current Population Survey Annual Social and Economic Supplement to examine rates of offer and take-up of employer-sponsored health insurance over early 2014 and early 2015, as well as reasons reported for why individuals did not enroll. We find increases in offer and eligible rates of 0.5 and 0.9 percentage points, respectively, and a decrease in the take-up rate of 1.5 percentage points, while the coverage rate remained stable. We further find an increase in the proportion of workers covered by another plan and decreases in the proportions eligible for coverage but having a preexisting condition, employed as contract or temporary employees not allowed in the plan, and who have not yet worked for an employer long enough.

The article demonstrates that a public institution like Team Danmark in its relations with the public as well as with the athletes runs a high risk for exposing hypocrisy and double standards when they ignore that it is the will to victory and not the virtues of the English gentleman sport that is the driving...... on the international arenas. The problems of the governement sponsored elite sport institution Team Danmark', is not only seen in their moral panic following doping cases that hardly can be surprising, but also in the institutions ambiguous handling of and advisory to athletes about the use of grey area products...

    This document contains the results of a collection of selected cooperative research projects between principal investigators in the microgravity combustion science programs, sponsored by NASA and NEDO. Cooperation involved the use of drop towers in Japan and the United States, and the sharing of subsequent research data and findings. The topical areas include: (1) Interacting droplet arrays, (2) high pressure binary fuel sprays, (3) sooting droplet combustion, (4) flammability limits and dynamics of spherical, premixed gaseous flames and, (5) ignition and transition of flame spread across thin solid fuel samples. All of the investigators view this collaboration as a success. Novel flame behaviors were found and later published in archival journals. In some cases the experiments provided verification of the design and behavior in subsequent experiments performed on the Space Shuttle. In other cases, the experiments provided guidance to experiments that are expected to be performed on the International Space Station.

    Employer-sponsored health insurance premiums rose moderately in 2013, the annual Kaiser Family Foundation/Health Research and Educational Trust (Kaiser/HRET) Employer Health Benefits Survey found. In 2013 single coverage premiums rose 5 percent to $5,884, and family coverage premiums rose 4 percent to $16,351. The percentage of firms offering health benefits (57 percent) was similar to that in 2012, as was the percentage of workers at offering firms who were covered by their firm's health benefits (62 percent). The share of workers with a deductible for single coverage increased significantly from 2012, as did the share of workers in small firms with annual deductibles of $1,000 or more. Most firms (77 percent), including nearly all large employers, continued to offer wellness programs, but relatively few used incentives to encourage employees to participate. More than half of large employers offering health risk appraisals to workers offered financial incentives for completing the appraisal.

This study focuses on a core relational concept found in workplaces, organizational identification-the feeling of belongingness-and the impact of partnering with employers and health clinics in health information dissemination. We use social-identity theory and multiple identification to test our predictions from a sample of working adults representing more than 100 different employers. We found that when people strongly identify with their employer, they have increased health behavioral intentions and they intend to talk about the health information with coworkers. The significant models explain more than 50% and 30% of the variance in these two outcomes. The experimental results examining single and multiple organizational sources revealed no differences on any outcomes. These findings offer a contribution to health information dissemination research by articulating how identification with an employer functions to affect behavioral intentions.

    Using two employer surveys, we evaluate the role of increased health maintenance organization (HMO) market share in containing costs of employer-sponsored coverage. Total costs for employer health plans are about 10 percent lower in markets in which HMOs' market share is above 45 percent than they are in markets with HMO enrollments of below 25 percent. This is the result of lower premiums for HMOs than for non-HMO plans, as well as the competitive effect of HMOs that leads to lower non-HMO premiums for employers that continue to offer these benefits. Slower growth in premiums in areas with high HMO enrollments suggests that expanded HMO market share may also lower the long-run growth in costs.

    Provider sponsored organizations (PSOs) are increasingly acquiring the risk for the management of Medicare Risk patients by accepting capitation directly from the Health Care Financing Administration (HCFA) or through contracts with HMOs or other organizations contracting with HCFA. The Medicare population and the requirements that the federal administration has put into place with respect to risk contracting are unique and demand specific responses on the part of the PSO for a contract to be successful. The PSO is cautioned to understand the actuarial risk, the clinical uniqueness of the Medicare beneficiary, Medicare reimbursement regulatory requirements, utilization management needs, and necessary reporting before entering into a contractual arrangement. This article attempts to describe some of the more common issues a provider organization must consider.

  8. Proposal to establish a Sponsoring Consortium for Open Access Publishing in Particle Physics

    CERN Document Server

    CERN. Geneva

    2007-01-01

    In the present proposal, the publishers' subscription income from multiple institutions is replaced by an "author-side" funding. Journals are paid through contracts between publishers and a single financial partner, the "Sponsoring Consortium for Open Access Publishing in Particle Physics" (SCOAP3). SCOAP3 is envisioned as a global network of funding agencies, research laboratories, and libraries that will contribute the necessary funding; each SCOAP3 partner will recover its contribution from the cancellation of journal subscriptions. This model avoids the obvious disadvantage of authors being directly charged for the OA publication of their articles, which is perceived as an even higher barrier than subscription charges, in particular for theoretical physicists from small institutions who account for the vast majority of HEP papers. The financing and governance of SCOAP3 will follow as much as possible the example of the memoranda of understanding governing large research collaborations. Its partners will c...

  9. Policy uncertainty and corporate performance in government-sponsored voluntary environmental programs.

    This study combines insights from the policy uncertainty literature and neo-institutional theory to examine corporate performance in implementing a government-sponsored voluntary environmental program (VEP) during 2004-2012 in Guangzhou, China. In this regulatory context, characterized by rapid policy changes, corporate performance in VEPs is affected by government surveillance, policy uncertainty, and peer pressures. Specifically, if VEP participants have experienced more government surveillance, they tend to perform better in program implementation. Such positive influence of government surveillance is particularly evident among those joining under high and low, rather than moderate uncertainty. Participants also perform better if they belong to an industry with more certified VEP firms, but worse if they are located in a regulatory jurisdiction with more certified VEP firms. At a moderate level of policy uncertainty, within-industry imitation is most likely to occur but within-jurisdiction imitation is least likely to occur. Copyright © 2018 Elsevier Ltd.

  10. Vioxx redux - or how I learned to worry about industry-sponsored clinical trials.

    Brophy, James M

    2016-01-01

    I read with interest Mark Wilson's recent article, "The New England Journal of Medicine: commercial conflict of interest and revisiting the Vioxx scandal". I believe this is an important contribution that underlines the aphorism "Those who don't know history are doomed to repeat it." As Vioxx is a seminal example, it is important to place it in its proper context, examining if this malfeasance extends beyond the VIGOR study. While the epicentre of this conflict of interest surely begins with the sponsor, I believe the following essay demonstrates that this wave of egregiously unethical behaviour can exist and be propagated only with the complicity of academic investigators, medical journals, a flawed peer-review system and an uncritical medical readership. Perhaps the most troubling is that the factors that coalesced into the Vioxx scandal are, if anything, more ubiquitous today, mandating increased vigilance to decrease the probability of "getting fooled" again.

    Disparities in glycemic control are reported in children with type 1 diabetes related to differences in access to health care and socioeconomic status. In the US military, rank is an indicator of socioeconomic status, but all have complete health care access without cost. We sought to determine if glycemic control in children with type 1 diabetes differs if their sponsor (parent) is an officer vs. enlisted military service member. We performed a cross-sectional retrospective chart review of children with type 1 diabetes >1 yr duration whose parent is a military service member. A total of 281 subjects met study criteria, 136 (48.4%) having an enlisted and 145 (51.6%) having an officer sponsor. The groups differed by race with 38.2% black in the enlisted and 9% black in the officer group (p 1). The median enlisted average hemoglobin A1c (HbA1c) over the most recent year of available data was significantly higher than the officer group (9.2 vs. 8.4%, p 1). The difference remained significant when controlled for age and race. Diabetes-related hospitalizations were greater in the enlisted group (39.0 vs. 19.3%, p 1). More subjects in the officer group were on insulin pumps (54.5 vs. 28.7%, p 1). Dependent children of enlisted service members with type 1 diabetes have higher HbA1c levels, more diabetes-related hospitalizations, and are less likely to use insulin pumps than children of officers. These differences are likely linked to socioeconomic status and education levels given the universal access to health care within the military system. Published 2015.

    2017-01-01

    The Lunar and Planetary Institute (LPI) and the Astromaterials Research and Exploration Science (ARES) Division, part of the Exploration Integration and Science Directorate at NASA Johnson Space Center (JSC), co-sponsored a training session in November 2016 for four early-career scientists in the techniques of coordinated analysis. Coordinated analysis refers to the approach of systematically performing high-resolution and -precision analytical studies on astromaterials, particularly the very small particles typical of recent and near-future sample return missions such as Stardust, Hayabusa, Hayabusa2, and OSIRIS-REx. A series of successive analytical steps is chosen to be performed on the same particle, as opposed to separate subsections of a sample, in such a way that the initial steps do not compromise the results from later steps in the sequence. The data from the entire series can then be integrated for these individual specimens, revealing important in-sights obtainable no other way. ARES/JSC scientists have played a leading role in the development and application of this approach for many years. Because the coming years will bring new sample collections from these and other planned NASA and international exploration missions, it is timely to begin disseminating specialized techniques for the study of small and precious astromaterial samples. As part of the Cooperative Agreement between NASA and the LPI, this training workshop was intended as the first in a series of similar training exercises that the two organizations will jointly sponsor in the coming years. These workshops will span the range of analytical capabilities and sample types available at ARES/JSC in the Astromaterials Research and Astro-materials Acquisition and Curation Offices. Here we summarize the activities and participants in this initial training.

    Assuming that preventive measures to avoid reactor pressure vessel (RPV) failure under core degradation scenarios have failed, the stabilisation of the core melts after its release from the RPV is a key issue. Adequate cooling of the ex-vessel corium and the control of its interactions with the coolant and structures are the main challenges to mitigate and stabilise the situation preserving the containment integrity. In this regard, the on-going Fourth Euratom Framework Programme (4 th EFP) contributes with experimental and theoretical research activities aimed at responding to the main challenges mentioned, by satisfying three objectives: - To improve the understanding of the basic physics related to ex-vessel corium behaviour from the phenomenological and technological viewpoints, as well as to provide a methodology for investigating it and setting up joint multi-partner projects to be co-sponsored and co-ordinated by the EC; - to quantify and reduce the uncertainties associated with the risk issues by conducting experimental and numerical investigations and eventually to achieve a European consensus on the phenomenology and on accident mitigation strategies; - to provide a technological response to the risk issues by developing engineered safety systems (e.g. core-catchers) and severe accident management strategies (e.g. guidelines), and to discuss such a technological response with the end users of these technologies, i.e. designers and licensers. To fulfil these objectives, the 4 th EFP co-sponsors a total of five projects within the cluster 'Ex-Vessel Corium Behaviour and Coolability' of the Nuclear Fission Safety Programme. The research undertaken addresses the main different aspects such as the determination of the composition and thermodynamic data of the melt; experiments on spreading behaviour on various types of surfaces, as well as on corium coolability by flooding or water injection; investigation of corium stratification, crust and heat transfer

    Maternal employment has been one of the greatest barriers to breastfeeding. Women are increasingly solving this problem by expressing milk at work and taking it home to their infants. The objective was to determine duration of breast milk expression among working mothers enrolled in an employer-sponsored lactation program. Retrospective reviews were conducted on the lactation records of 462 women employed by 5 corporations in order to describe and characterize their experiences. The lactation program included the employees' choice of (a) a class on the benefits of breastfeeding; (b) services of a certified lactation consultant (CLC); and (c) private room in the workplace with equipment for pumping. Breastfeeding was initiated by 97.5% of the participants, with 57.8% continuing for at least 6 months. Of the 435 (94.2%) who returned to work after giving birth, 343 (78.9%) attempted pumping milk at work, and 336 (98%) were successful. They expressed milk in the workplace for a mean of 6.3 months (SD = 3.9, range 2 weeks to 21 months). The mean age of infants when the mothers stopped pumping at work was 9.1 months (SD = 4.1, range 1.9 to 25 months). Most of the women who pumped their milk at work were working full time (84.2%). The mean postnatal maternity leave was 2.8 months. The proportion of women who chose to pump at work was higher among women who were salaried than among those who were paid hourly wages (p < 0.01). Company-sponsored lactation programs can enable employed mothers to provide breast milk for their infants as long as they wish, thus helping the nation attain the Healthy People 2010 goals of 50% of mothers breastfeeding until their infants are 6-months-old.

    2017-08-26

    The integrity of the medical literature about robotic surgery remains unclear despite wide-spread adoption. We sought to determine if payment from Intuitive Surgical Incorporated (ISI) affected quality of the research produced by surgeons. Publicly available financial data from the CMS website regarding the top-20 earners from ISI for 2015 was gathered. Studies conducted by these surgeons were identified using PubMed. Inclusion criteria consisted of publications about the da Vinci ® robot on patient outcomes. The primary outcome of our study was if the study conclusion was positive/equivocal/negative towards the robot. Secondary outcomes included authorship, sponsorship, study controls, and disclosure. The top earners received $3,296,844 in 2015, with a median of $141,959. Sub-specialties included general surgery (55%), colorectal (20%), thoracic (15%), and obstetrics/gynecology (10%). Of the 37 studies, there was 1 RCT, with observational studies comprising the rest. The majority of the studies (n = 16, 43%) had no control population, with 11 (30%) comparing to same institution/surgeon, Though ISI sponsored only 6 (16%) studies, all with positive conclusions, 27 (73%) studies had positive conclusions for robot use, 9 (24%) equivocal, and only 1 (3%) negative. Overall, 13 earners had lead authorship and 11 senior. This initial pilot study highlights a potential bias as current literature published by benefactors demonstrates low quality and highly positive conclusions towards approval of the robot. This substantiates the need for a large, systematic review of the potential influence of sponsoring surgeons on medical literature. Copyright © 2017 Elsevier Inc. All rights reserved.

    This article builds on an earlier viewpoint regarding the need for project-focussed fieldwork. It presents the findings of an evaluative study into the value of project placements undertaken by final year graduate entry master's students as part of a capstone subject. The authors argue that provision of project placements enable impending graduates to develop and implement macro level strategies to develop prevention, resource and service development skills often required of contemporary occupational therapy practitioners. A qualitative approach is adopted. Student cohorts from 2005 and 2006 completed open-ended, written questionnaires, and agency project sponsors were interviewed to obtain their perspectives of the project placement experience. Despite some concern that project placements might be undertaken at the expense of 'clinical' placements these findings reveal that projects managed by students were perceived by services to add great value enabling them to advance important priorities. Students and sponsors highlighted a range of positive learning outcomes, including the ability to work collaboratively with supervisors and develop advanced communication skills and political acumen. The success of such placements depends on supportive supervision from academic staff. CONCLUSIONS AND SIGNIFICANCE OF THE STUDY: The findings promote project placements as a highly authentic aspect of work integrated learning enabling learners to draw together a range of attributes that support the ability to manage complex issues that have occupational relevance at a macro level. In addition, such experiences help learners to develop agency and political acumen both increasingly important capabilities for the contemporary workplace. © 2012 The Authors Australian Occupational Therapy Journal © 2012 Occupational Therapy Australia.

    Only 53% and 63% of studies and clinical trials results presented at congresses are published. Company-sponsored trial results are being posted on publicly accessible Web sites. We analyzed the public availability (publication or posting on a Web site) rate, time to publication, and factors predicting public availability of results of studies sponsored by a pharmaceutical company. This was a retrospective cohort study analyzing all studies conducted by GlaxoSmithKline in Spain between 2001 and 2006. Initiation and completion were defined as first participant/first visit and last participant/last visit (or their equivalents). Papers published up to 31 March 2009 were considered. Logistic regression models were used to identify factors predicting public availability of results. The cohort comprised 143 studies (94 clinical trials; of these, 87 were included in international products clinical development plans). Public availability rate was 80% (114/143) for all studies and 78% (73/94) for clinical trials; publication rates were 68% and 61%, respectively. The median time to publication for all studies and trials was 27.3 and 28.4 months, respectively. Study associated to a cancelled project was the only significant factor associated with lower publication rate for all studies [odds ratio (OR) 0.069; 95% confidence interval (CI) 0.02-024; p public availability rate (OR 0.052; 95% CI 0.007-0.382; p = 0.004) for trial results. Therapy area, sample size, positive trial results, duration of experimental phase, and being a clinical trial did not predict publication or public availability. Eighty percent of studies included in this analysis are publicly available. Web site posting increases public availability rate of clinical trial results from 61% to 78%. Cancellation of projects is the single factor negatively influencing publication and public availability rates.

    Industry-sponsored websites for robotic surgery direct to surgeons listed as performing specific robotic surgical procedures. The purpose of this study was to compare average annual, surgeon-specific, case volumes for those procedures for which they were listed as performing on the commercial website with the volumes of all providers performing these same procedures across a defined geographic region. A list of providers within the state of Wisconsin cited as performing specific urologic procedures was obtained through the Intuitive Surgical website 〈http://www.davincisurgery.com/da-vinci-urology/〉. Surgeon-specific annual case volumes from 2009 to 2013 for these same cases were obtained for all Wisconsin providers through DataBay Resources (Warrendale, PA) based on International classification of diseases-9 codes. Procedural activity was rank ordered, and surgeons were placed in "volume deciles" derived from the total annual number of cases performed by all surgeons. The distribution of commercially listed surgeon volumes, both 5-year average and most recent year, was compared with the average and 2013 volumes of all surgeons performing a specific procedure. A total of 35 individual urologic surgeons listed as performing robotic surgery in Wisconsin were identified through a "search" using the Intuitive Surgical website. Specific procedure analysis returned 5, 12, 9, and 15 surgeon names for cystectomy, partial nephrectomy, radical nephrectomy, and prostatectomy, respectively. This compared with the total number of surgeons who had performed the listed procedure in Wisconsin at least 1 time during the prior 5 years of 123, 153, 242, and 165, respectively. When distributed by surgeon-volume deciles, surgeons listed on industry-sponsored sites varied widely in their respective volume decile. More than half of site-listed, procedure-specific surgeons fell below the fifth decile for surgeon volume. Data analysis based solely on 2013 case volumes had no effect on

    Online forums and partnerships with patients have several benefits, such as the creation of new products and services. However, as with any such initiatives, there are risks as well as benefits. Through analysis of a case of misinformation being spread through a health care provider-sponsored online support group for patients dealing with obesity, this article outlines best practices and strategies to deploy in such organization-sponsored patient support groups. These strategies would enable organizations and patients to use such forums to the fullest extent while preventing or managing their potential risks as best as possible. © 2017 American Medical Association.

    D. T. Gillespie recently derived a random variable transformation theorem relating to the joint probability densities of functionally dependent sets of random variables. The present author points out that the theorem can be derived as an immediate corollary of a simpler and more fundamental relation. In this relation the probability density is represented as a delta function averaged over an unspecified distribution of unspecified internal random variables. The random variable transformation is derived from this relation

  2. The effectiveness of environmental education programs from the perspectives of three stakeholders: Participants, sponsors, and professionals

    Luera, Gail Rose

    As the field of environmental education has matured since its inception in 1970, so have the number and variety of environmental programs. Along with the increased number of programs has come a need for in-depth program evaluations. This is especially critical because of reductions in educational funding and competition for a place in an already crowded curriculum. Evaluation is essential to convince the educational community that environmental education can improve the curriculum, ensure cost effectiveness, and become more relevant to students. Drawing on program evaluation research, action research, and interpretive (qualitative) research to strengthen the research design and methodology, this dissertation explores how different stakeholders of two environmental education programs determine program effectiveness. Effectiveness was investigated primarily through the use of in-depth interviews of participants, program sponsors, and professionals. Program success at the professional field level was determined by criteria set by the North American Association for Environmental Education. Characteristics considered in the selection of programs for this study included: method of dissemination, sponsor, subject focus, the method of action which they encourage, and their vision for the future. Using the qualitative case study approach, the Orange County Outdoor Science School in California and Project WILD in Michigan were evaluated. The results show that all levels of stakeholders perceived the two programs to be effective. Areas of effectiveness varied with each program and by stakeholder level. Issues facing each program also differed. At the Orange County Outdoor Science School, program cost was named as the major issue. The most often cited issues for Project WILD was public awareness of the program and stabilizing long term financial support for the Michigan program. Interview data were analyzed at the question level in addition to the thematic level. Themes which

    Our objective was to describe the implementation and clinical outcomes of an employer-sponsored, pharmacist-provided medication therapy management (MTM) program for health plan beneficiaries with diabetes mellitus and/or hypertension. We conducted a single-center retrospective medical record review. The setting was a Pharmacy MTM Clinic at a self-insured health system consisting of six hospitals and several ancillary facilities. A total of 161 health plan beneficiaries with diabetes identified during annual wellness screenings for the health plan in 2012 and 225 health plan beneficiaries with diabetes and/or hypertension identified during annual wellness screenings for the health plan in 2013 were referred to the MTM clinic based on specific criteria. In 2012 the health system expanded its existing wellness program by implementing a voluntary diabetes care program for health plan beneficiaries with uncontrolled diabetes (hemoglobin A(1c) [A1C] 7% or higher); a similar program was added for hypertension for the 2013 plan year. All participants' A1C and blood pressure results were tracked from the date of their wellness screening through the end of the plan year. The pharmacists involved had the capability to directly implement drug regimen changes according to hospital protocol or provide recommendations to the physician, as specified by the referring physician. For the 2012-2013 plan year, the mean difference in A1C from baseline to program completion was -0.38% (95% confidence interval [CI] -0.58 to -0.18%, p<0.05). For beneficiaries with a baseline A1C of 7% or higher, the mean difference was -0.69% (95% CI -0.99 to -0.39%, p<0.05). For the 2013-2014 plan year, the mean difference in A1C from baseline to program completion was -0.62% (95% CI -0.81 to -0.44%, p<0.05). In that year, the mean difference in A1C for beneficiaries with A1C 7% or higher was -0.97% (95% CI -1.23 to -0.72%, p<0.05). For those referred for hypertension, a mean difference of -13 mm Hg (95

  17. The Tax Exclusion for Employer-Sponsored Insurance Is Not Regressive-But What Is It?

    Science.gov (United States)

    White, Joseph

    2017-08-01

    Conventional wisdom says that the tax exclusion for employer-sponsored health insurance (ESI) is "regressive and therefore unfair." Yet, by the standard definition of regressive tax policy, the conventional view is almost certainly false. It confuses the absolute size of the tax exclusion with its proportional effect on income. The error results from paying attention only to the marginal tax rate applied to ESI benefits as a portion of income and ignoring the fact that benefits are normally a much larger share of income for people with lower wages. This article explains the difference and then considers other distributional effects of ESI. It suggests that ESI-for those who receive it-further redistributes toward those with lesser means or greater need. The most evident effect is by need, favoring employees with families over those without. Yet there is good reason to believe there is also a redistribution by income, with the package of wages plus benefits being less unequal than wages alone would be. Therefore reformers should be much more careful before criticizing either ESI or its subsidy through the tax code as "unfair," especially as the likelihood of enacting something better in the United States seems quite low.

  18. A Christian faith-based recovery theory: understanding God as sponsor.

    Timmons, Shirley M

    2012-12-01

    This article reports the development of a substantive theory to explain an evangelical Christian-based process of recovery from addiction. Faith-based, 12-step, mutual aid programs can improve drug abstinence by offering: (a) an intervention option alone and/or in conjunction with secular programs and (b) an opportunity for religious involvement. Although literature on religion, spirituality, and addiction is voluminous, traditional 12-step programs fail to explain the mechanism that underpins the process of Christian-based recovery (CR). This pilot study used grounded theory to explore and describe the essence of recovery of 10 former crack cocaine-addicted persons voluntarily enrolled in a CR program. Data were collected from in-depth interviews during 4 months of 2008. Audiotapes were transcribed verbatim, and the constant comparative method was used to analyze data resulting in the basic social process theory, understanding God as sponsor. The theory was determined through writing theoretical memos that generated key elements that allow persons to recover: acknowledging God-centered crises, communicating with God, and planning for the future. Findings from this preliminary study identifies important factors that can help persons in recovery to sustain sobriety and program administrators to benefit from theory that guides the development of evidence-based addiction interventions.

  19. Does company-sponsored egg freezing promote or confine women's reproductive autonomy?

    Mertes, Heidi

    2015-08-01

    A critical ethical analysis of the initiative of several companies to cover the costs of oocyte cryopreservation for their healthy employees. The main research question is whether such policies promote or confine women's reproductive autonomy. A distinction needs to be made between the ethics of AGE banking in itself and the ethics of employers offering it to their employees. Although the utility of the former is expected to be low, there are few persuasive arguments to deny access to oocyte cryopreservation to women who are well informed about the procedure and the success rates. However, it does not automatically follow that it would be ethically unproblematic for employers to offer egg banking to their employees. For these policies to be truly 'liberating', a substantial number of conditions need to be fulfilled, which can be reduced to three categories: (1) women should understand the benefits, risks and limitations, (2) women should feel no pressure to take up the offer; (3) the offer should have no negative effect on other family-friendly policies and should in fact be accompanied by such policies. Fulfilling these conditions may turn out to be impossible. Thus, regardless of companies' possible good intentions, women's reproductive autonomy is not well served by offering them company-sponsored AGE banking.

  20. NRC sponsored rotating equipment vibration research: a program description and progress report

    1986-01-01

    The Idaho National Engineering Laboratory (INEL) is currently involved in a research project sponsored by the United States Nuclear Regulatory Commission (NRC) regarding operational vibration in rotating equipment. The object of this program is to assess the nature of vibrational failures and the effect that improved qualification standards may have in reducing the incidence of failure. In order to limit the scope of the initial effort, safety injection (SI) pumps were chosen as the component group for concentrated study. The task has been oriented to addressing the issues of whether certain SI pumps experience more failures than others, examining the dynamic environments in operation, examining the adequacy of current qualification standards, and examining what performance parameters could be used more efficiently to predict degradation or failure. Results of a literature search performed to survey SI pump failures indicate that failures are due to a diversity of causes, many of which may not be influenced by qualification criteria. Cooperative efforts have been undertaken with a limited number of nuclear utilities to describe the variety of possible operating environments and to analyze available data. The results of this analysis as they apply to the research issues are presented and possibilities for the future direction of the program are discussed

    Full Text Available This study aims to investigate to what extent does a Fantasy Sports Game (FSG brand community’s members Identification and Engagement influence their Membership Continuance Intention as well as their perception of the brand equity of the FSG’s sponsor. The Consumer Culture Theory – CCT  CITATION Arn05 \\l 1046 (Arnould & Thompson, 2005 was used as the theoretical framework for this study, more specifically situated in the brand community group of CCT studies. The ‘Social Influence of Brand Communities’ model  CITATION Alg05 \\l 1046 (Algesheimer, Dholakia, & Herrmann, 2005 was used as the basis for the development of the conceptual model of this study, which focused on the players of Cartola FC, the most important Brazilian football (soccer FSG. A non-probabilistic judgment sample was collected through a web survey focusing on the Cartola FC’s official Facebook fan page members resulting in 3,710 valid responses. The constructs’ reliability, as well as their convergent, discriminant and nomological validities were assessed. Structural equation modeling was used to test the substantive hypotheses of this study. Five of the six substantive hypotheses were empirically supported. The results suggest that the sponsor’s consumer based brand equity is positively influenced by the brand communities members engagement and membership continuance intention.

  2. Should nutritional supplements and sports drinks companies sponsor sport? A short review of the ethical concerns.

    Science.gov (United States)

    Outram, Simon M; Stewart, Bob

    2015-06-01

    This paper proposes that the sponsorship of sport by nutritional supplements and sport drinks companies should be re-examined in the light of ethical concerns about the closeness of this relationship. A short overview is provided of the sponsorship of sport, arguing that ethical concerns about its appropriateness remain despite the imposition of severe restrictions on tobacco sponsorship. Further, the paper examines the main concerns about supplement use and sports drinks with respect to efficacy, health and the risks of doping. Particular consideration is given to the health implications of these concerns. It is suggested that they, of themselves, do not warrant the restriction of sponsorship by companies producing supplements and sports drinks. Nevertheless, it is argued that sports sponsorship does warrant further ethical examination--above and beyond that afforded to other sponsors of sport--as sport sponsorship is integral to the perceived need for such products. In conclusion, it is argued that sport may have found itself lending unwarranted credibility to products which would otherwise not necessarily be seen as beneficial for participation in sports and exercise or as inherently healthy products.

    Studies done in the mid-1970s documented increased risk for respiratory cancer and leukemia among employees in a chemical company manufacturing plant where chloromethyl ethers were used in production from 1948 to 1971. In the late 1980s, the company informed current and former employees about the results of follow-up studies which showed a moderation of risk of respiratory cancer and leukemia. New data showing elevated rates of mortality from colorectal, prostate, bladder, and pancreatic cancer in the population were also reported. Via mailed correspondence, the company made a no-cost program of colorectal and prostate cancer screening available to employees upon request; and information about bladder and pancreatic cancer was made available. Thirteen percent of employees in the population indicated interest in colorectal and prostate cancer screening (response). Thirty-one percent of these responders were screened (adherence). Multivariate analyses showed that education and length of employment in the plant were positively associated with response. Being white was positively associated with response for younger workers; while among older workers being male was positively associated with response. In terms of adherence, we found that older, more highly educated workers were more likely to have a screening examination. Findings indicate that employee participation in workplace-sponsored colorectal and prostate cancer screening can vary according to worker sociodemographic factors and length of employment in areas of potential exposure.

    This invention describes an automatic variable collimator which controls the width and thickness of X-ray beams in X-ray diagnostic medical equipment, and which is particularly adapted for use with computerized axial tomographic scanners. A two-part collimator is provided which shapes an X-ray beam both prior to its entering an object subject to radiographic analysis and after the attenuated beam has passed through the object. Interposed between a source of radiation and the object subject to radiographic analysis is a first or source collimator. The source collimator causes the X-ray beam emitted by the source of radiation to be split into a plurality of generally rectangular shaped beams. Disposed within the source collimator is a movable aperture plate which may be used to selectively vary the thickness of the plurality of generally rectangular shaped beams transmitted through the source collimator. A second or receiver collimator is interposed between the object subject to radiographic analysis and a series of radiation detectors. The receiver collimator is disposed to receive the attenuated X-ray beams passing through the object subject to radiographic analysis. Located within the receiver collimator are a plurality of movable aperture plates adapted to be displaced relative to a plurality of fixed aperture plates for the purpose of varying the width and thickness of the attenuated X-ray beams transmitted through the object subject to radiographic analysis. The movable aperture plates of the source and receiver collimators are automatically controlled by circuitry which is provided to allow remote operation of the movable aperture plates

    The Accreditation Council for Graduate Medical Education (ACGME) requires the graduate medical education committee and the designated institutional official to ensure that citations for noncompliance with the accreditation standards and institutional trends in citations are reviewed and corrected. To describe a citation tracking system (CTS) that uses Microsoft Office Access to efficiently catalogue, monitor, and document resolution of citations. The CTS was implemented in a sponsoring institution with oversight of 133 ACGME-accredited programs. The designated institutional official and the graduate medical education committee review all program letters of notification and enter citations into the CTS. A program-correction plan is required for each citation and is entered into the database. Open citations and action plans are reviewed by the graduate medical education committee and the designated institutional official on a quarterly basis, with decisions ranging from "closing" the citation to approving the action plan in process to requiring a new or modified action plan. Citation categories and subcategories are accessed on the ACGME website and entered into the CTS to identify trends. All 236 citations received since the 2006 Mayo School of Graduate Medical Education institutional site visit were entered into the CTS. On November 22, 2011, 26 of 236 citations (11%) were in active status with ongoing action plans, and 210 (89%) citations had been resolved and were closed. The CTS uses commercially available software to ensure citations are monitored and addressed and to simplify analysis of citation trends. The approach requires minimal staff time for data input and updates and can be performed without institutional information technology assistance.

    Mental illness in children increases the risk of developing mental health disorders in adulthood, and reduces physical and emotional well-being across the life course. The Mental Health Parity and Addiction Equity Act (MHPAEA, 2008) aimed to improve access to mental health treatment by requiring employer-sponsored health plans to include insurance coverage for behavioral health services. Investigators used IBM Watson/Truven Analytics MarketScan claims data (2007-2013) to examine: (1) the distribution of mental illness; (2) trends in utilization and out-of-pocket expenditures; and (3) the overall effect of the MHPAEA on mental health services utilization and out-of-pocket expenditures among privately-insured children aged 3 to 17 with mental health disorders. Multivariate Poisson regression and linear regression modeling techniques were used. Mental health services use for outpatient behavioral health therapy (BHT) was higher in the years after the implementation of the MHPAEA (2010-2013). Specifically, before the MHPAEA implementation, the annual total visits for BHT provided by mental health physicians were 17.1% lower and 2.5% lower for BHT by mental health professionals, compared to years when MHPAEA was in effect. Children covered by consumer-driven and high-deductible plans had significantly higher out-of-pocket expenditures for BHT compared to those enrolled PPOs. Our findings demonstrate increased mental health services use and higher out-of-pocket costs per outpatient visit after implementation of the MHPAEA. As consumer-driven and high-deductible health plans continue to grow, enrollees need to be cognizant of the impact of health insurance benefit designs on health services offered in these plans.

  7. Primary care COPD patients compared with large pharmaceutically-sponsored COPD studies: an UNLOCK validation study.

    Directory of Open Access Journals (Sweden)

    Annemarije L Kruis

    Full Text Available BACKGROUND: Guideline recommendations for chronic obstructive pulmonary disease (COPD are based on the results of large pharmaceutically-sponsored COPD studies (LPCS. There is a paucity of data on disease characteristics at the primary care level, while the majority of COPD patients are treated in primary care. OBJECTIVE: We aimed to evaluate the external validity of six LPCS (ISOLDE, TRISTAN, TORCH, UPLIFT, ECLIPSE, POET-COPD on which current guidelines are based, in relation to primary care COPD patients, in order to inform future clinical practice guidelines and trials. METHODS: Baseline data of seven primary care databases (n=3508 from Europe were compared to baseline data of the LPCS. In addition, we examined the proportion of primary care patients eligible to participate in the LPCS, based on inclusion criteria. RESULTS: Overall, patients included in the LPCS were younger (mean difference (MD-2.4; p=0.03, predominantly male (MD 12.4; p=0.1 with worse lung function (FEV1% MD -16.4; p<0.01 and worse quality of life scores (SGRQ MD 15.8; p=0.01. There were large differences in GOLD stage distribution compared to primary care patients. Mean exacerbation rates were higher in LPCS, with an overrepresentation of patients with ≥ 1 and ≥ 2 exacerbations, although results were not statistically significant. Our findings add to the literature, as we revealed hitherto unknown GOLD I exacerbation characteristics, showing 34% of mild patients had ≥ 1 exacerbations per year and 12% had ≥ 2 exacerbations per year. The proportion of primary care patients eligible for inclusion in LPCS ranged from 17% (TRISTAN to 42% (ECLIPSE, UPLIFT. CONCLUSION: Primary care COPD patients stand out from patients enrolled in LPCS in terms of gender, lung function, quality of life and exacerbations. More research is needed to determine the effect of pharmacological treatment in mild to moderate patients. We encourage future guideline makers to involve primary care

  8. The Role of a Provider-Sponsored Health Plan in Achieving Scale and Integration.

    In pursuit of two primary strategies-to become an integrated delivery network (IDN) on the local level and to achieve additional overall organizational scale to sustain operations-Health First, based in Rockledge, Florida, relies on the success of its provider-sponsored health plan (PSHP) as a critical asset. For Health First, the PSHP serves as an agent for holding and administering financial risk for the health of populations. In addition, we are learning that our PSHP is a critical asset in support of integrating the components of our care delivery system to manage that financial risk effectively, efficiently, and in a manner that creates a unified experience for the customer.Health First is challenged by continuing pressure on reimbursement, as well as by a substantial regulatory burden, as we work to optimize the environments and tools of care and population health management. Even with strong margins and a healthy balance sheet, we simply do not have the resources needed to bring an IDN robustly to life. However, we have discovered that our PSHP can be the vehicle that carries us to additional scale. Many health systems do not own or otherwise have access to a PSHP to hold and manage financial risk. Health First sought and found a not-for-profit health system with complementary goals and a strong brand to partner with, and we now provide private-label health plan products for that system using its strong name while operating the insurance functions under our license and with our capabilities.

    2014-12-01

    The NSF-sponsored Summit on the Future of Undergraduate Geoscience Education made major progress toward developing a collective community vision for the geosciences. A broad spectrum of the geoscience education community, ~200 educators from research universities/four and two year colleges, focused on preparation of undergraduates for graduate school and future geoscience careers, pedagogy, use of technology, broadening participation/retention of underrepresented groups, and preparation of K-12 science teachers. Participants agreed that key concepts, competencies and skills learned throughout the curriculum were more important than specific courses. Concepts included understanding Earth as complex, dynamic system, deep time, evolution of life, natural resources, energy, hazards, hydrogeology, surface processes, Earth materials and structure, and climate change. Skills/competencies included ability to think spatially and temporally, reason inductively and deductively, make and use indirect observations, engage in complex open, coupled systems thinking, and work with uncertainty, non-uniqueness, and incompleteness, as well as critical thinking, problem solving, communication, and ability to think like a scientist and continue to learn. Successful ways of developing these include collaborative, integrative projects involving teams, interdisciplinary projects, fieldwork and research experiences, as well as flipped classrooms and integration and interactive use of technology, including visualization, simulation, modeling and analysis of real data. Wider adoption of proven, effective best practices is our communities' main pedagogical challenge, and we focused on identifying implementation barriers. Preparation of future teachers in introductory and general geoscience courses by incorporating Next Generation Science Standards and using other sciences/math to solve real world geoscience problems should help increase diversity and number of future geoscientists and

  10. Skin injuries from discrete radioactive particles: A summary of EPRI-sponsored experiments. Final report

    1994-12-01

    In recent years there has been the debate over the risk to nuclear power plant workers from beta radiation-emitting discrete radioactive particles (or DRPs). DRPs-sometimes called open-quotes hot particlesclose quotes-are small, often microscopic, radioactive particles that can adhere to the skin and protective clothing of plant workers. They can potentially produce high radiation doses to very small areas of the skin. Concern is based on the knowledge that various types of nonstochastic skin injuries can result from sufficiently high beta radiation doses. While the effects for large-area irradiations (several square centimeters and larger) are generally well understood, the effects for doses to very small areas are less clear. However, the evidence is clear that the doses required to produce skin injuries from DRP irradiations are significantly larger than the dose limits prescribed in existing regulations for large-area skin exposures. One concern is that nuclear power plant efforts to comply with skin dose limits causes workers to receive unnecessary whole-body radiation exposure. In addition, DRP protection measures focus radiation protection resources on very low risk hazards, and may not be an optimum use of radiation protection resources. EPRI sponsored a series of irradiation experiments to address some of the DRP exposure issues. This report summarizes the results of experiments using sources covering a range of sizes and beta energies, simulating both activation product and fuel-bearing DRPS. NCRP Publication 106 states that all of these small skin injuries are minor, but that acute deep ulceration should be avoided. Accordingly, this research focused on open sores or scabs that remain unhealed for very long times. The ED 50 dose for these injuries was determined to be about 5 krad (50 Gy). A revised guideline might lower whole-body exposures associated with DRP control measures, while not significantly increasing the likelyhood of DRP injuries

    Postgraduate medical education in Singapore underwent major transition recently, from a British-style system and accreditation to a competency-based residency programme modelled after the American system. We aimed to identify the relative importance of factors influencing the choice of residency sponsoring institutions (SIs) among medical students during this transition period. A questionnaire-based cross-sectional study of Singaporean undergraduate medical students across all years of study was performed in 2011. Participants rated 45 factors (including research, academia and education, marketing, reputation of faculty, working conditions, posting experience and influence by peers/seniors) for degree of importance to their choice of SIs on a five-point Likert scale. Differences with respect to gender and seniority were compared. 705 of 1,274 students completed the survey (response rate 55.3%). The top five influencing factors were guidance by mentor (4.48 ± 0.74), reputation for good teaching (4.46 ± 0.76), personal overall experience in SIs (4.41 ± 0.88), quality of mentorship and supervision (4.41 ± 0.75), and quality and quantity of teaching (4.37 ± 0.78). The five lowest-rated factors were social networking (2.91 ± 1.00), SI security (3.01 ± 1.07), open house impact (3.15 ± 0.96), advertising paraphernalia (3.17 ± 0.95) and research publications (3.21 ± 1.00). Female students attributed more importance to security and positive work environment. Preclinical students rated research and marketing aspects more highly while clinical students valued positive work environment more. Quality of education, mentorship, experiences during clerkship and positive working environment were the most important factors influencing the choice of SIs.

    The last decade has seen dramatic changes in the regulatory landscape to support more trials involving children, but child-specific challenges and inequitable conduct across income regions persist. The goal of this study was to describe the attitudes and opinions of stakeholders toward trials in children, to inform additional strategies to promote more high-quality, relevant pediatric trials across the globe. Key informant semi-structured interviews were conducted with stakeholders (researchers, regulators, and sponsors) who were purposively sampled from low- to middle-income countries and high-income countries. The transcripts were thematically analyzed. Thirty-five stakeholders from 10 countries were interviewed. Five major themes were identified: addressing pervasive inequities (paucity of safety and efficacy data, knowledge disparities, volatile environment, double standards, contextual relevance, market-driven forces, industry sponsorship bias and prohibitive costs); contending with infrastructural barriers (resource constraints, dearth of pediatric trial expertise, and logistical complexities); navigating complex ethical and regulatory frameworks ("draconian" oversight, ambiguous requirements, exploitation, excessive paternalism and precariousness of coercion versus volunteerism); respecting uniqueness of children (pediatric research paradigms, child-appropriate approaches, and family-centered empowerment); and driving evidence-based child health (advocacy, opportunities, treatment access, best practices, and research prioritization). Stakeholders acknowledge that changes in the regulatory environment have encouraged more trials in children, but they contend that inequities and political, regulatory, and resource barriers continue to exist. Embedding trials as part of routine clinical care, addressing the unique needs of children, and streamlining regulatory approvals were suggested. Stakeholders recommended increasing international collaboration

    conjunction with the variability in the measured tree-growth curve. These provide detailed information on growth conditions and variations in temperature during the period 165 B.C. - A.D. 1400. The correlation of the present data with the previously published results from northern Sweden display great general similarity, but also some significant differences. We propose that the combined data give a more reliable indication of regional climatic variations and that the differences are due to local factors at the two locations. The similarity between these two independent series supports general conclusions made about changing summer climate over Fennoscandia after A.D. 500 and strongly suggests that our conclusions drawn here for the period 165 B.C. - A.D. 500 are on a firm basis. The present data thus enable us to infer the record of summer climate variability in northern Fennoscandia about 600 years back in time. Most of the subfossil pines preserved in the lake grew very close to the place where they were found. Reaction wood indicating tilting of the trunk, probably caused by rising water levels, was found in several trees. These trees grew on the lake shore where the soil was soft or eroding. The large number of relatively young trees indicates that storms may have occasionally felled pines. This cannot be proven (by demonstrating a common death year however, because the outermost tree rings in the subfossil material are frequently decayed. A small number of the pines found in Lake Ailigas were cut by Man. The pines, identified by axe marks may be remnants of barriers built by the Prehistoric Saami for hunting of wild reindeer. The dates of these indicate that traps were constructed in the mid 9th century and at the end of the 11th and start of the 12th centuries, i.e. late Iron Age times.

Besides the investigations of LWR tasks also projects on the safety of advanced reactors are sponsored by the BMFT. The individual reports are classified according to the research program on the safety of LWRs 1977-1980 of the BMFT. Another table of contents uses the same classification system as applied in the nuclear safety index of the CEC (Commission of the European Communities) and the OECD (Organization for Economic Cooperation and Development). The reports are arranged in the sequence of their project numbers. (orig./HP) [de

  19. Identifying associations between sport sponsorship decision-making variables

    2004-04-01

    Full Text Available Sport sponsorship spending in South Africa has increased steadily. This paper discusses the findings of an exploratory study into key sponsorship decision-areas, namely the setting of sponsorship objectives, the integration of marketing communication variables into sponsorship to create a leverage effect, and the measurement of sponsorship success. It is argued that for a sponsorship to be successful certain associations should exist between these key decision-making areas and also among elements internal to each of these areas. The main findings are that the respondents indicated a bias towards setting media related objectives that will subsequently enable the sponsors to use media-related measurement tools. It is recommended that sponsors should develop alternative methods to measure the effectiveness of their sponsorships.

    To identify the elements necessary for successful collaboration between patient groups and academic and industry sponsors of clinical trials, in order to develop recommendations for best practices for effective patient group engagement. In-depth interviews, informed by a previously reported survey, were conducted to identify the fundamentals of successful patient group engagement. Thirty-two respondents from 3 sectors participated: patient groups, academic researchers, and industry. The findings were presented to a multistakeholder group of experts in January 2015. The expert group came to consensus on a set of actionable recommendations for best practices for patient groups and research sponsors. Interview respondents acknowledged that not all patient groups are created equal in terms of what they can contribute to a clinical trial. The most important elements for effective patient group engagement include establishing meaningful partnerships, demonstrating mutual benefits, and collaborating as partners from the planning stage forward. Although there is a growing appreciation by sponsors about the benefits of patient group engagement, there remains some resistance and some uncertainty about how best to engage. Barriers include mismatched expectations and a perception that patient groups lack scientific sophistication and that "wishful thinking" may cloud their recommendations. Patient groups are developing diverse skillsets and acquiring assets to leverage in order to become collaborators with industry and academia on clinical trials. Growing numbers of research sponsors across the clinical trials enterprise are recognizing the benefits of continuous and meaningful patient group engagement, but there are still mindsets to change, and stakeholders need further guidance on operationalizing a new model of clinical trial conduct.

    Recent state budget crises have dramatically reduced funding for state-sponsored antitobacco media campaigns. If campaigns are associated with reduced smoking, such cuts could result in long-term increases in state health care costs. Commercial ratings data on mean audience exposure to antitobacco advertising that appeared on network and cable television across the largest 75 media markets in the United States for 1999 through 2000 were combined with nationally representative survey data from school-based samples of youth in the contiguous 48 states. Multivariate regression models were used to analyze associations between mean exposure to state antitobacco advertising and youth smoking-related beliefs and behaviors, controlling for individual and environmental factors usually associated with youth smoking and other televised tobacco-related advertising. Mean exposure to at least 1 state-sponsored antitobacco advertisement in the past 4 months was associated with lower perceived rates of friends' smoking (odds ratio [OR], 0.72; 95% confidence interval [CI], 0.58-0.88), greater perceived harm of smoking (OR, 1.25; 95% CI, 1.11-1.42), stronger intentions not to smoke in the future (OR, 1.43; 95% CI, 1.17-1.74), and lower odds of being a smoker (OR, 0.74; 95% CI, 0.63-0.88). To our knowledge, this study is the first to explore the potential impact of state-sponsored antitobacco media campaigns while controlling for other tobacco-related advertising and other tobacco control policies. State-sponsored antitobacco advertising is associated with desired outcomes of greater antitobacco sentiment and reduced smoking among youth. Recent cuts in these campaigns may have future negative health and budgetary consequences.

    Abstract ¾ Many students are uncomfortable with real world engineering problems where needs and requirements must be concretely defined and the selection of design solutions is not black and white. This paper describes a two semester, multi-disciplinary senior capstone project for students from three Engineering and Technology Department programs (electrical engineering, electrical and computer engineering technology, and engineering technology that brings together the tools of project management and the creative product development process into industry sponsored projects.  The projects are fully integrated with the Center for Rapid Product Realization with its dual goals of economic development and enhanced learning.  The stage/gate development process is used with six formal reviews covering the development of the proposal through to the fabrication and testing of the project’s output.  Over the past four years thirty five (35 projects have been undertaken with students getting an exciting

  9. Employer-sponsored long-term care insurance: best practices for increasing sponsorship.

    Science.gov (United States)

    Pincus, J

    2000-04-01

    Behind the enthusiasm of policymakers for long-term care (LTC) insurance is the belief that increased ownership of private LTC insurance will reduce the government's future liability for financing the nation's LTC needs, currently projected by the Congressional Budget Office to increase by 2.6 percent annually between 2000 and 2040. Some observers say that sustained economic growth could keep these increased expenditures at the same share of total GDP; others argue that current federal expenditure trends will become unsustainable without large tax increases. The potential of the employer-sponsored group LTC market to stave off a national LTC financing crisis has recently started to receive popular notice in the news media. However, for the potential of the group LTC market to be realized, there must be widespread employer sponsorship of group LTC plans and significant participation levels among eligible employees in these plans. The present analysis of industry data estimates the LTC plan sponsorship rate for all U.S. employers with 10 or more employees at 0.2 percent. The sponsorship rate among large employers is significantly higher (8.7 percent). The greatest growth opportunities are projected to lie in the smaller employer market, because it is enormous and virtually untapped. Nonsponsors cite a variety of barriers to employer sponsorship of LTC plans. For many nonsponsors, the most important obstacles are the intrinsic characteristics of their work forces: employees are too young, transient, part-time, and/or low-income to be suitable for LTC insurance. For many others, lack of awareness and low priority are the primary obstacles. Because group LTC insurance has been widely available for only 10 years, many benefits managers view it as "too new and untested." Prior to the passage of the Health Insurance Portability and Accountability Act (HIPAA), in August 1996, the tax treatment of long-term care insurance premiums was unclear because Congress had not

    The purpose of this study was to investigate medical service quality, satisfaction and to examine factors influencing hospital revisit intention of the United Arab Emirates government sponsored patients in Korea. A total of 152 UAE government sponsored patients who visited Korean hospitals participated in the questionnaire survey from August to November 2016. Stepwise multiple regression was used to identify the factors that affected the revisit intention of the participants. The mean scores of medical service quality, satisfaction, and revisit intention were 5.72 out of 7, 88.88 out of 100, 4.59 out of 5, respectively. Medical service quality and satisfaction, Medical service quality and revisit intention, satisfaction and revisit intention were positively correlated. Medical service of physician, visiting routes and responsiveness of medical service quality explained about 23.8% of revisit intention. There are needs for physicians to communicate with patients while ensuring sufficient consultation time based on excellent medical skills and nurses to respond immediately for the patients' needs through an empathic encounter in order to improve medical service quality and patient satisfaction so that to increase the revisit intention of the United Arab Emirates government sponsored patients. Further, it is necessary for the hospitals to have support plans for providing country specialized services in consideration of the UAE culture to ensure that physicians' and nurses' competencies are not undervalued by non-medical service elements such as interpreters and meals.

    Full Text Available The use of e-recruitment for hiring personnel is constantly expanding. However, the scientific understanding of factors affecting company employer brand during e-recruitment, is still poor. Research into corporate social responsibilities (CSR shows that information about the company’s involvement in these areas makes its image more positive, including its image as an employer. CSR is an umbrella concept, which includes activities similar to traditional sponsoring of sports and cultural events. Two theories explaining the impact of information on attractiveness of the employer’s brand in the e-recruitment process are presented. The aim of the text is to check which of them – cultural fit or signaling theory – more adequately explains the changes in how a candidate perceives a company’s attractiveness, when given information about its’ sports and cultural sponsoring and environment-related activities. The effect of both positive and negative information concerning a company’s activities on its employer image in the e-recruitment situation is analyzed. Data from an questionnaire filled in by 80 young full-time workers shows that positive information about a company’s CSR and sponsoring activities affects candidates according to the cultural fit model, while negative – according to the signaling theory model. The consequences for theory and managerial practice are described.

    To investigate patterns of industry-sponsored educational events that focus on specific health conditions for which there are concerns about overdiagnosis and overtreatment. This retrospective cohort study examines publicly reported industry-sponsored events in Australia from October 2011 to September 2015 for three conditions potentially subject to overdiagnosis and overtreatment: depression, osteoporosis and overactive bladder. We used a database of transparency reports to identify events with a focus on depression, osteoporosis and overactive bladder and compared these with other sponsored events. We hypothesised that companies marketing treatments for each condition would sponsor related events and that target audiences would mainly work in primary care, reflecting a broad patient population. Event and attendee characteristics, sponsoring companies, related marketed treatments, cost-effectiveness ratings and dispensing rates. Over the study period, we identified 1567 events focusing on depression, 1375 on osteoporosis and 190 on overactive bladder (total n=3132, with 96 660 attendees). These events were attended by primary care doctors more often than sponsored events without a focus on these three conditions: relative risk (RR)=3.06 (95% CI 2.81 to 3.32) for depression, RR=1.48 (95% CI 1.41 to 1.55) for osteoporosis and RR=2.59 (95% CI 2.09 to 3.21) for overactive bladder. Servier, which markets agomelatine and AstraZeneca (quetiapine) sponsored 51.2% and 23.0% of depression events, respectively. Amgen and GlaxoSmithKline, which co-market denosumab, sponsored 49.5% of osteoporosis events and Astellas and Commonwealth Serum Laboratories (CSL) (mirabegron and solifenacin) sponsored 80.5% of overactive bladder events. This 4-year overview of industry-sponsored events on three overdiagnosed and overtreated conditions found that primary care clinicians were often targeted, dinner was often provided and that a few companies sponsored most events.

    1997-09-12

    In this report various forms of the Hamiltonian for particle motion in an accelerator will be derived. Except where noted, the treatment will apply generally to linear and circular accelerators, storage rings, and beamlines. The generic term accelerator will be used to refer to any of these devices. The author will use the usual accelerator coordinate system, which will be introduced first, along with a list of handy formulas. He then starts from the general Hamiltonian for a particle in an electromagnetic field, using the accelerator coordinate system, with time t as independent variable. He switches to a form more convenient for most purposes using the distance s along the reference orbit as independent variable. In section 2, formulas will be derived for the vector potentials that describe the various lattice components. In sections 3, 4, and 5, special forms of the Hamiltonian will be derived for transverse horizontal and vertical motion, for longitudinal motion, and for synchrobetatron coupling of horizontal and longitudinal motions. Hamiltonians will be expanded to fourth order in the variables.

    Full Text Available Gaurav Puppalwar, Meenakshi Mourya, Ganesh Kadhe, Amey Mane Medical Affairs, Wockhardt Limited, Wockhardt Towers, Bandra Kurla Complex, Mumbai, India Abstract: Clinical trials provide a foundation for new drug development processes, as well as for product license extensions for existing therapies. The reduction in the amount of time and cost to conduct a clinical trial becomes important, as competition to bring a new drug to the market is increasing, and so is the search for new markets. Kenya, Nigeria, Tanzania, Uganda, and Zambia offer a diverse patient population, as well as a comparatively research-friendly and ambitious government to develop these countries as pharmaceutical and health sectors of excellence. All these countries have their own guidelines to conduct clinical trials that feature some similarities and some subtle differences. Over the last decade, the guidelines have been evolving to provide a good ground to foreign sponsors, which carry out clinical trials while keeping the interest of patients as a priority. In the advent of these evolving guidelines, it becomes important for a foreign sponsor to understand and be aware of these guidelines before carrying out clinical trials. The present paper attempts to collect and compile all information available regarding the guidelines on the conduct of trials by a foreign sponsor in these five countries, which are available at government websites and search engines. The information gathered was organized into simplified flowcharts for easy understanding and usage. A clear understanding of the guidelines can effectively reduce the challenges faced for conducting clinical trials in these countries.

    Female representation in medicine is increasing across all levels of medical training, yet women hold fewer senior leadership positions than men. National recognition, including participation as faculty in society-sponsored programs, is one component of academic advancement. The aim of this study was to characterize female representation among faculty in courses sponsored by the American Society for Gastrointestinal Endoscopy (ASGE). We performed a retrospective review of demographic data, including faculty gender and role, year, and program type, from the ASGE database of its sponsored programs between 2009 and 2014. Female faculty rates were compared with the rate of female membership in the ASGE and by faculty role and course type over time. Between 2009 and 2014 there were a total of 2020 ASGE course faculty positions of which women comprised 19%. There was a significant increase in the proportion of women that served as course faculty over time (P < .0005). Female faculty participation exceeded the ASGE female domestic membership rate in all years. Women were more likely to serve as course directors than lecturers (25% vs 18%, P = .004) and to participate in smaller courses (P = .0003). We found an increase in female participation in ASGE programming over time, suggesting that specialty societies are making efforts to improve female representation at the national level. Future work should evaluate whether or not these opportunities translate into leadership roles for women within their own institutions or lead to promotions for women over time.

    We explored how often journal articles reporting HIV research sponsored by a developed country, but conducted in a developing country, mention research ethics committee (REC) approval from both countries, and what factors are involved. Of all such 2007 articles on Medline conducted in one of four developing countries (N = 154), only 52% mentioned such dual approval. Mention of dual vs. single approval was more likely among articles with ≥ 50% sponsor country authors, and the United States as the sponsor country. Also, dual approval was more likely among articles that mentioned informed consent and funding, had ≥ 50% sponsor country authors, were biomedical (vs. psychosocial), and appeared in journals adopting International Committee Medical Journal Editors (ICMJE) guidelines. Dual approval was thus obtained in only half of the articles and was associated with ethical and logistic issues, indicating the need for clearer and more universally accepted guidelines.

  7. Small employers and the challenge of sponsoring a retirement plan: results of the 1998 Small Employer Retirement Survey.

    Science.gov (United States)

    Yakoboski, P; Ostuw, P

    1998-10-01

    Forty-two million individuals work for small employers; 9 million are participating in an employment-based retirement plan, while 33 million are not participating in a plan. This Issue Brief examines the barriers that prevent small employers from sponsoring a retirement plan, their level of knowledge about plans, and changes that might lead to plan sponsorship. It also examines the motivations of small employers that sponsor retirement plans. Small employers identify three main reasons for not offering a plan: employees' preferences for wages and/or other benefits, administrative costs, and uncertain revenue that makes it difficult to commit to a plan. Small employers without plans report being familiar with 401(k) and profit-sharing plans, but little else. Forty-seven percent report never having heard of the savings incentive match plan for employees (SIMPLE), and 55 percent report never having heard of simplified employee pensions (SEPs). There is apparent misunderstanding about retirement plans among small employers that do not sponsor one, especially with regard to costs. For example, 35 percent do not know that a plan can be set up for less than $2,000. What changes would lead to serious consideration of retirement plan sponsorship? In order of reported importance: increased company profits (66 percent), a business tax credit (64 percent), reduced administrative requirements (50 percent), demand from employees (49 percent), allowing key executives to save more in the plan (49 percent), and easing, i.e., lengthening, of vesting requirements (40 percent). Many small employers that sponsor a retirement plan cite business reasons among their motivations. Sixty-eight percent cite a "positive effect on employee attitude and performance" as a major reason for offering a plan. Fifty-six percent cite a "competitive advantage in employee recruitment and retention" as a major reason. Small employers with a retirement plan report direct benefits from sponsorship, but many

    There are currently thirteen members of the AGF, government-sponsored research organizations who together employ more than 22.000 people and an annual budget of about DM 2.5 billions, thus representing the largest, compact research potential of the Federal Republic of Germany and building one of the most essential elements of the German scientific research system. The research organizations are financed from Federal Government funds and by contributions from the Federal Land the organization is domiciled, each at a ratio of 90 to 10. Influence and control by the Federal Government is exerted by way of Government representatives having a seat and a vote in the executive bodies of the organization, and by way of budgetary powers. Ever since their establishment, the government-sponsored research organizations have to find a balance between the two poles of scientific and legal independence on the one hand, and governmental influence on the other. Their wish for more effectively safeguarding their common interests have induced the research organizations to establish the AGF on January 30, 1970. (orig./HSCH) [de

    2008-01-01

    Full Text Available The number of companies that are exposed to the revenues loss risk caused by weather variability is still increasing. The businesses that are mostly exposed to weather risk are following: energy, agriculture, constructions and transport. That situation has initiated dynamic growth of weather derivatives markets as well as the awareness of the weather risk among the market participants. Presently, the weather derivatives markets evaluate rapidly in all the mature economies: USA, Asia and Europe. Constructing weather derivatives relies on qu- antifying climate factors in the form of indexes, what is quite simple task, more difficultly can be gathering precise historical data of required climate factors. Taking into consideration so far development of derivatives especially the financial derivatives based on different types of indexes financial market has at disposal wide range of different types of proved derivatives (futures, forward, options, swaps, which can be successfully utilised on the weather-driven markets both for hedging weather risk and speculating.

  3. Real Time Data for Seismology at the IRIS Data Management Center, AN Nsf-Sponsored Facility

    2012-12-01

    When IRIS was incorporated in 1984, it committed to provide long-term support for the science of seismology. It first upgraded analog networks by installing observatory grade digital seismic recording equipment (by constructing the Global Seismic Network to upgrade the World Wide Standardized Seismographic Network) that became the backbone of the International Federation of Digital Seismic Networks (FDSN), and in 1990 constructed a state-of-the-art data center that would allow free and open access to data to everyone. For the first decade, IRIS leveraged a complicated system of telemetry which laid the foundation for delivering (relatively) high rate and continuous seismic time series data to the IRIS Data Management Center, which was designed to accept data that arrived with highly variable latencies and on many media formats. This meant that science had to often wait until data became complete, which at the time was primarily related to studying earthquakes or similar events. During the 1990's, numerous incremental but small improvements were made to get data into the hands of users with less latency, leveraging dialup, satellite telemetry, and a variety of Internet protocols. But beginning in 2000, the IRIS Data Management Center began the process of accumulating data comprehensively in real time. It was first justified because it eliminated the time-consuming transcription and manual data handling on various media formats, like magnetic tapes, CD's and DVD's. However, the switch to real-time telemetry proved to be a major improvement technologically because it not only simplified data transfer, it opened access to a large volume of previously inaccessible data (local resource limitations), and many networks began willingly providing their geophysical data to the broad research community. It also enabled researchers the ability to process data in different and streamlined ways, by incorporating data directly into workflows and processing packages. Any network on

  4. A structural econometric model of family valuation and choice of employer-sponsored health insurance in the United States.

    Science.gov (United States)

    Vanness, David J

    2003-09-01

    This paper estimates a fully structural unitary household model of employment and health insurance decisions for dual wage-earner families with children in the United States, using data from the 1987 National Medical Expenditure Survey. Families choose hours of work and the breakdown of compensation between cash wages and health insurance benefits for each wage earner in order to maximize expected utility under uncertain need for medical care. Heterogeneous demand for the employer-sponsored health insurance is thus generated directly from variations in health status and earning potential. The paper concludes by discussing the benefits of using structural models for simulating welfare effects of insurance reform relative to the costly assumptions that must be imposed for identification.

    The aim of this study was to identify areas of consensus in response to proposed Equal Employment Opportunity Commission Americans with Disabilities Act of 1990 and Genetic Information Nondiscrimination Act of 2008 regulations on employer-sponsored health, safety, and well-being initiatives. The consensus process included review of existing and proposed regulations, identification of key areas where consensus is needed, and a methodical consensus-building process. Stakeholders representing employees, employers, consulting organizations, and wellness providers reached consensus around five areas, including adequate privacy notice on how medical data are collected, used, and protected; effective, equitable use of inducements that influence participation in programs; observance of reasonable alternative standards; what constitutes reasonably designed programs; and the need for greater congruence between federal agency regulations. Employee health and well-being initiatives that are in accord with federal regulations are comprehensive, evidence-based, and are construed as voluntary by employees and regulators alike.

    Increasing participation of registered nurses (RNs) in quality improvement (QI) is a promising strategy to close the health care quality chasm. For RNs to participate effectively in hospital QI, they must have adequate QI knowledge and skills. This descriptive study assessed employer-sponsored QI education and RNs' preparedness across a wide range of QI steps and processes. RNs from 15 U.S. states who were employed in hospitals and were initially licensed to practice in 2007 to 2008 were surveyed. Fewer than one third of respondents reported being very prepared across all measured QI topics. More than half reported receiving zero hours of training in these same topics in the last year. Lack of educational offerings on the topic was the top reason respondents gave for not obtaining QI training. The QI education offered by employers to RNs could be substantially improved. Nurse educators play a critical role in making these improvements. Copyright 2013, SLACK Incorporated.

    The purpose of this study was to determine how children cognitively and emotionally process interactive marketing of snack food products in advergames. Children (N = 30) aged 10 to 12 were asked to play advergames with (a) avatars that were assigned to them, (b) avatars chosen from a pool, and (c) self-designed avatars. The children's skin conductance levels were collected during play. After gameplay, at each customization level, self-reported presence was collected. The results of this study indicate that customization of game avatars can affect both subjective feelings of presence and psychophysiological indicators of emotion during gameplay, which may make the gameplay experience more enjoyable. This may have implications for game sponsors and producers. Self-reported presence had no effect on psychophysiological indicators of emotion during gameplay. Implications of this finding and limitations of this study are discussed.

  8. Progressive or regressive? A second look at the tax exemption for employer-sponsored health insurance premiums.

    Science.gov (United States)

    Schoen, Cathy; Stremikis, Kristof; Collins, Sara; Davis, Karen

    2009-05-01

    The major argument for capping the exemption of health insurance benefits from income tax is that doing so will generate significant revenue that can be used to finance an expansion of health coverage. This analysis finds that given the state of insurance markets and current variations in premiums, limiting the current exemption could adversely affect individuals who are already at high risk of losing their health coverage. Evidence suggests that capping the exemption for employment-based health insurance could disproportionately affect workers in small firms, older workers, and wage-earners in industries with high expected claims costs. To avoid putting many families at increased health and financial risk, and to avoid undermining employer-sponsored group coverage, any consideration of a cap would have to be combined with coverage for all, changes in insurance market rules, and shared responsibility for financing.

    Masses are derived for the individual components of six cataclysmic variables. There is a considerable spread in the masses of the white dwarf components, which range from 0.73 M/sub sun/ in EM Cyg to 1.26 M/sub sun/ in Z Cam. All of the white dwarfs have masses greater than 0.70 M/sub sun/, but there is no evidence that there is any preferred mass. It is found that the morphology of the eruptions (i.e., nova versus dwarf nova) is independent of the mass of both the white dwarf and the late-type star

A total of 36 studies were selected. Of these, 24 were original studies, including 21 experimental studies and three clinical studies. Several experimental studies reported the beneficial effects of distinct variable ventilation strategies on lung function using different models of lung injury and healthy lungs. Variable ventilation seems to be a viable strategy for improving gas exchange and respiratory mechanics and preventing lung injury associated with mechanical ventilation. However, further clinical studies are necessary to assess the potential of variable ventilation strategies for the clinical improvement of patients undergoing mechanical ventilation.

    Internet-based marketing has become an attractive option for promoting tobacco products due to its potential to avoid advertising restrictions. In Argentina, several cigarette brands have designed websites for the local market, which promote user participation. The intent of the study was to report on the use of tobacco company-sponsored websites by medical students and recently graduated physicians. An online self-administered survey was conducted among eligible medical students and recent graduates from the University of Buenos Aires (UBA). Sampling was from lists of email addresses of students enrolled in two required courses. Eligibility criteria were ages 18-30 years and reporting on smoking status. Questions on Internet use included accessing a tobacco brand website at least once during their lifetime and any use of tobacco promotional materials. The response rate was 35.08% (1743/4969). The final sample included 1659 participants: 73.06% (1212/1659) were women and mean age was 26.6 years (SD 1.9). The majority were current medical students (55.70%, 924/1659) and 27.31% (453/1659) were current smokers. Men were more likely to report having seen a tobacco advertisement on the Internet (P=.001), to have received a tobacco promotion personally addressed to them (P=.03), to have used that promotion (P=.02), and to have accessed a tobacco-sponsored website (P=.01). Among respondents, 19.35% (321/1659) reported having accessed a tobacco-sponsored website at least once in their lifetime and almost all of them (93.8%, 301/321) accessed these sites only when it was necessary for participating in a marketing promotion. Most people logging on for promotions reported entering once a month or less (58.9%, 189/321), while 25.5% (82/321) reported accessing the tobacco industry Internet sites once a week or more. In adjusted logistic regression models, participants were more likely to have accessed a tobacco brand website if they were former smokers (OR 2.45, 95% CI 1

    On the basis of studies on second partial derivatives of the variable transformation functions for nine different non-normal variables the paper comprehensively discusses the effects of the transformation on FORM results and shows that senses and values of the errors in FORM results depend on distributions of the basic variables, whether resistances or actions basic variables represent, and the design point locations in the standard normal space. The transformations of the exponential or Gamma resistance variables can generate +24% errors in the FORM failure probability, and the transformation of Frechet action variables could generate -31% errors

  5. Dynamics of Variable Mass Systems

    1998-01-01

    This report presents the results of an investigation of the effects of mass loss on the attitude behavior of spinning bodies in flight. The principal goal is to determine whether there are circumstances under which the motion of variable mass systems can become unstable in the sense that their transverse angular velocities become unbounded. Obviously, results from a study of this kind would find immediate application in the aerospace field. The first part of this study features a complete and mathematically rigorous derivation of a set of equations that govern both the translational and rotational motions of general variable mass systems. The remainder of the study is then devoted to the application of the equations obtained to a systematic investigation of the effect of various mass loss scenarios on the dynamics of increasingly complex models of variable mass systems. It is found that mass loss can have a major impact on the dynamics of mechanical systems, including a possible change in the systems stability picture. Factors such as nozzle geometry, combustion chamber geometry, propellant's initial shape, size and relative mass, and propellant location can all have important influences on the system's dynamic behavior. The relative importance of these parameters on-system motion are quantified in a way that is useful for design purposes.

  6. Fields of rational constants of cyclic factorizable derivations

    Directory of Open Access Journals (Sweden)

    Janusz Zielinski

    2015-12-01

    Full Text Available We describe all rational constants of a large family of four-variable cyclic factorizable derivations. Thus, we determine all rational first integrals of their corresponding systems of differential equations. Moreover, we give a characteristic of all four-variable Lotka-Volterra derivations with a nontrivial rational constant. All considerations are over an arbitrary field of characteristic zero. Our main tool is the investigation of the cofactors of strict Darboux polynomials. Factorizable derivations are important in derivation theory. Namely, we may associate the factorizable derivation with any given derivation of a polynomial ring and that construction helps to determine rational constants of arbitrary derivations. Besides, Lotka-Volterra systems play a significant role in population biology, laser physics and plasma physics.

  7. The role of corruption and unethical behaviour in precluding the placement of industry sponsored clinical trials in sub-Saharan Africa: Stakeholder views.

    2016-08-15

    Clinical trials still represent the gold standard in testing the safety and efficacy of new and existing treatments. However, developing regions including sub-Saharan Africa remain underrepresented in pharmaceutical industry sponsored trials for a number of reasons including fear of corruption and unethical behaviour. This fear exists both on the part of pharmaceutical companies, and investigators carrying out research in the region. The objective of this research was to understand the ethical considerations associated with the conduct of pharmaceutical industry sponsored clinical trials in sub-Saharan Africa. Corruption was identified as a significant issue by a number of stakeholders who participated in semi-structured interviews and completed questionnaires. Additionally, fear of being perceived as corrupt or unethical even when conducting ethically sound research was raised as a concern. Thus corruption, whether actual or perceived, is one of a number of issues which have precluded the placement of a greater number of pharmaceutical sponsored clinical trials in this region. More discussion around corruption with all relevant stakeholders is required in order for progress to be made and to enable greater involvement of sub-Saharan African countries in the conduct of industry sponsored clinical trials.

    2001-01-01

    Cataclysmic variable stars are the most variable stars in the night sky, fluctuating in brightness continually on timescales from seconds to hours to weeks to years. The changes can be recorded using amateur telescopes, yet are also the subject of intensive study by professional astronomers. That study has led to an understanding of cataclysmic variables as binary stars, orbiting so closely that material transfers from one star to the other. The resulting process of accretion is one of the most important in astrophysics. This book presents the first account of cataclysmic variables at an introductory level. Assuming no previous knowledge of the field, it explains the basic principles underlying the variability, while providing an extensive compilation of cataclysmic variable light curves. Aimed at amateur astronomers, undergraduates, and researchers, the main text is accessible to those with no mathematical background, while supplementary boxes present technical details and equations.

  16. Understanding Brown Dwarf Variability

    Science.gov (United States)

    Marley, Mark S.

    2013-01-01

    Surveys of brown dwarf variability continue to find that roughly half of all brown dwarfs are variable. While variability is observed amongst all types of brown dwarfs, amplitudes are typically greatest for L-T transition objects. In my talk I will discuss the possible physical mechanisms that are responsible for the observed variability. I will particularly focus on comparing and contrasting the effects of changes in atmospheric thermal profile and cloud opacity. The two different mechanisms will produce different variability signatures and I will discuss the extent to which the current datasets constrain both mechanisms. By combining constraints from studies of variability with existing spectral and photometric datasets we can begin to construct and test self-consistent models of brown dwarf atmospheres. These models not only aid in the interpretation of existing objects but also inform studies of directly imaged giant planets.

    Learning experiences for middle school girls are an effective means to steer young women toward secondary engineering curricula that they might not have otherwise considered. Sponsorship of such experiences by a collegiate student group is worthwhile, as it gives the group common purpose and places college students in a position to mentor these young women. This paper addresses learning experiences in different areas of bio-medical engineering offered to middle school girls in November 2008 via a day-long workshop entitled "Engineering The Body." The Kansas State University (KSU) Student Chapter of the IEEE Engineering in Medicine and Biology Society (EMBS) worked with the KSU Women in Engineering and Science Program (WESP) to design and sponsor these experiences, which addressed the areas of joint mechanics, electrocardiograms, membrane transport, computer mouse design, and audio filters for cochlear implants. Fifty five middle-school girls participated in this event, affirming the notion that biomedical engineering appeals to young women and that early education and recruitment efforts have the potential to expand the biomedical engineering talent pool.

     Under the Japanese drug regulatory system, post-marketing studies (PMS) must be in compliance with Good Post-marketing Study Practice (GPSP). The GPSP Ordinance lacks standards for the ethical conduct of PMSs; although only post-marketing clinical trials are subject to Good Clinical Practice. We conducted a web-based questionnaire survey on the ethical conduct of PMSs in collaboration with the Japanese Society of Hospital Pharmacists and pharmacists belonging to the Society. 1819 hospitals around Japan answered the questionnaire, of which 503 hospitals had conducted company-sponsored PMSs in 2015. 40.2% of the hospitals had obtained informed consent from participating patients in at least one PMS conducted in 2015, the majority of which was in written form. The first and second most frequent reasons for seeking informed consent in PMSs were to meet protocol requirements, followed by the requirement to meet institutional standard operational procedures and the request of the ethical review board of the hospital. Ethical review of PMSs was conducted in 251 hospitals. Despite a lack of standards for informed consent and ethical review in PMSs, a considerable number of study sites employed informed consent and ethical review for PMSs. While company policies and protocols are likely to be major determinants of the ethical conduct of PMSs, the governmental regulatory agency should also play a significant role in implementing a standardized ethical code for the conduct of PMSs.

    Pacific Northwest Laboratory (PNL) is currently conducting research for the US Nuclear Regulatory Commission (NRC) on uranium recovery process wastes for both active and inactive operations. NRC-sponsored uranium recovery research at PNL is focused on NRC regulatory responsibilities for uranium-recovery operations: license active milling and in situ extraction operations; concur on the acceptability of DOE remedial-action plans for inactive sites; and license DOE to maintain inactive sites following remedial actions. PNL's program consists of four coordinated projects comprised of a program management task and nine research tasks that address the critical technical and safety issues for uranium recovery. Specifically, the projects endeavor to find and evaluate methods to: prevent erosion of tailings piles and prevent radon release from tailings piles; evaluate the effectiveness of interim stabilization techniques to prevent wind erosion and transport of dry tailings from active piles; estimate the dewatering and consolidation behavior of slurried tailings to promote early cover placement; design a cover-protection system to prevent erosion of the cover by expected environmental stresses; reduce seepage into ground water and prevent ground-water degradation; control solution movement and reaction with ground water in in-situ extraction operations; evaluate natural and induced restoration of ground water in in-situ extraction operations; and monitor releases to the environment from uranium recovery facilities

    1998-11-01

    A number of clinical trials sponsored by the National Institutes of Health (NIH) use rigorous methods of data acquisition and analysis previously developed in fundamental biology and the physical sciences. The naive expectation that these trials would lead relatively rapidly to definitive answers concerning the therapeutic strategies and techniques under study is dispelled. This presentation focuses on delineating differences between the study of central tendencies and individual variation, more specifically on the strategy to study this variation: measure additional sources of variance within each patient at more timepoints and perhaps with greater precision. As rigorous orthodontic research is still in its infancy, the problem of defining the proper mix between prospective and retrospective trials is discussed. In view of the high costs of prospective clinical trials, many of the questions germane to orthodontics can be answered by well-conducted retrospective trials, assuming that properly randomized sampling procedures are employed. Definitive clinical trials are likely to require better theoretical constructs, better instrumentation, and better measures than now available. Reasons for concern are the restricted resources available and the fact that current mensurational approaches may not detect many of the individual differences. The task of constructing sharable databases and record bases stored in digital form and available either remotely from servers, or locally from CD-ROMs or optical disks, is crucial to the optimization of future investigations.

    Meals served at government-run day care centers must be nutritionally adequate to ensure good health and proper development of preschool-aged children. They can provide a controlled opportunity to complement the daily diet of children in vulnerable populations. To determine the nutrient adequacy and leading food sources of nutrients provided by the diet served in government-sponsored day care centers. Estimated daily energy and nutrient intakes of a theoretical 40-day day care center menu were calculated, and the nutrient adequacy was assessed. Nutrient densities and critical nutrient densities of the menu were computed to identify nutrient inadequacies. Furthermore, main sources of nutrients were identified, and energy and nutrient distributions were examined by meal time. The menu provides approximately 90% of daily energy requirement and more than 100% of Recommended Nutrient Intakes (RNIs), with the exception of vitamin D and calcium. Sugar was the first leading source of energy, whereas milk was the first leading contributor of vitamin D. Within an environment of budgetary constraints, the Guatemalan government developed and advocated an exemplary menu offering for children in the vulnerable preschool period. We have demonstrated that, if prepared and served as planned, the items from the official, standard menu would supply most of the nutrients needed. High vitamin A intake related to the mandated national fortification program is a potential problem. From the analysis, it was found that vitamin D emerges as the most prominent candidate for a problem nutrient of deficient intake. © The Author(s) 2015.

    We present a successful model for organizing a small University-sponsored summer camp that integrates astronomy and physics content with other science disciplines and computer programming content. The aim of our science and technology camp is to engage middle school students in a wide array of critical thinking tasks and hands-on activities centered on science and technology. Additionally, our program seeks to increase and maintain STEM interest among children, particularly in under-represented populations (e.g., Hispanic, African-American, women, and lower socioeconomic individuals) with hopes of decreasing disparities in diversity across many STEM fields.During this four-day camp, organized and facilitated by faculty volunteers, activities rotated through many STEM modules, including optics, telescopes, circuit building, computer hardware, and programming. Specifically, we scaffold camp activities to build upon similar ideas and content if possible. Using knowledge and skills gained through the AAS Astronomy Ambassadors program, we were able to integrate several astronomy activities into the camp, leading students through engaging activities, and conduct educational research. We present best practices on piloting a similar program in a university environment, our efforts to connect the learning outcomes common across all the modules, specifically in astronomy and physics, outline future camp activities, and the survey results on the impact of camp activities on attitudes toward science, technology, and science careers.

The most important variable is personnel with regards to training, qualification, integrity, data recording, and data analysis. Although the data is very limited, these data indicate that, if the procedure is carefully controlled, reliability of defect detection and reproducibility of results are both approximately 90 percent for reliability of detection, this applies to relatively small defects as reliability increases substantially as defect size increases above the recording limit.

    Science.gov (United States)

    Chemical spills and associated deaths in the US has increased 2.6-fold and 16-fold from 1983 to 2012, respectfully. In addition, the number of chemicals to which humans are exposed to in the environment has increased almost 10-fold from 2001 to 2013 within the US. Internationally, a WHO report on the global composite impact of chemicals on health reported that 16% of the total burden of cardiovascular disease was attributed to environmental chemical exposure with 2.5 million deaths per year. Clearly, the cardiovascular system, at all its various developmental and life stages, represents a critical target organ system that can be adversely affected by existing and emerging chemicals (e.g., engineered nanomaterials) in a variety of environmental media. The ability to assess chemical cardiac risk and safety is critically needed but extremely challenging due to the number and categories of chemicals in commerce, as indicated. This presentation\\session will evaluate the use of adult human stem cell derived cardiomyocytes, and existing platforms, as an alternative model to evaluate environmental chemical cardiac toxicity as well as provide key information for the development of predictive adverse outcomes pathways associated with environmental chemical exposures.

    Linguistic and cultural differences can impede comprehension among potential research participants during the informed consent process, but how researchers and IRBs respond to these challenges in practice is unclear. We conducted in-depth interviews with 15 researchers, research ethics committee (REC) chairs and members from 8 different countries with emerging economies, involved in HIV-related research sponsored by HIV Prevention Trials Network (HPTN), regarding the ethical and regulatory challenges they face in this regard. In the interviews, problems with translating study materials often arose as major concerns. Four sets of challenges were identified concerning linguistic and cultural translations of informed consent documents and other study materials, related to the: (1) context, (2) process, (3) content and (4) translation of these documents. Host country contextual issues included low literacy rates, education (e.g., documents may need to be written below 5th grade reading level), and experiences with research, and different views of written documentation. Certain terms and concepts may not exist in other languages, or have additional connotations that back translations do not always reveal. Challenges arise because of not only the content of word-for-word, literal translation, but the linguistic form of the language, such as tone (e.g., appropriate forms of politeness vs. legalese, seen as harsh), syntax, manner of questions posed, and the concept of the consent); and the contexts of use affect meaning. Problems also emerged in bilateral communications--US IRBs may misunderstand local practices, or communicate insufficiently the reasons for their decisions to foreign RECs. In sum, these data highlight several challenges that have received little, if any, attention in past literature on translation of informed consent and study materials, and have crucial implications for improving practice, education, research and policy, suggesting several strategies

    In China, with the restructuring of health care system moving forward, private community health facilities have been playing a complementary but increasingly important role in providing public health and basic medical care services in urban areas. However, only limited evidence is available concerning the service functions of private community health facilities in China. The aim of this study was to explore the functions of private community health stations (PCHSs) to provide evidence-based recommendations for policy-making and practice in the development of urban community health services systems. A total of 818 PCHSs and 4320 government-sponsored community health stations (GCHSs) located in 28 cities of China were investigated in 2008. The percentages of stations that provided health services and the annual workload per community health worker (CHW) were compared between the two types of institutions. The results showed that the percentages of PCHSs providing public health services were significantly higher than those of GCHSs (P0.05). The annual workloads of all the public health services and basic medical services per CHW in PCHSs were lighter than those in GCHSs (P0.05). At present, the GCHSs are still the mainstream in urban China, which will last for a long period in future. However, our findings showed that the annual workloads of CHWs in PCHSs were no heavier than those in GCHSs, and the PCHSs were willing to provide public health services. In view of current inadequacy of health resources in China, it is feasible to further develop PCHSs under the guidance of the government, given that PCHSs can perform the basic functions of community health services, which is useful for the formation of public-private partnerships (PPP) and the improvement of community health services.

We find a series of nine absorption lines with a velocity of 0.24c from an ultra-fast outflow. For the first time, we are able to see extremely rapid variability of the UFO features, and can link this to the X-ray variability from the inner accretion disk. We find a clear flux dependence of the outflow features, suggesting that the wind is ionized by increasing X-ray emission.

    This paper presents the development of a magnetorheological (MR) fluid-based variable stiffness and damping isolator for vibration suppressions. The MR fluid isolator used a sole MR control unit to achieve the variable stiffness and damping in stepless and relative large scope. A mathematical model of the isolator was derived, and a prototype of the MR fluid isolator was fabricated and its dynamic behavior was measured in vibration under various applied magnetic fields. The parameters of the model under various magnetic fields were identified and the dynamic performances of isolator were evaluated.

    BVRI observations of known and suspected variables in the globular cluster 47 Tuc are described. Twelve period determinations were made, seven of which are new. The non-Mira stars are found to vary in a semi-regular manner, regardless of period. Values of Tsub(eff), Msub(bol) and Q, the pulsation constant, are derived by combining the BVRI with JHKL observations made near the same epoch. The results strongly favour pulsation in an overtone mode for both the Mira and semi-regular variables in 47 Tuc. There is also evidence of mode 'switching' for V4. (author)

    Throughout the domain of the H R diagram lie groupings of stars whose luminosity varies with time. These variable stars can be classified based on their observed properties into distinct types such as β Cephei stars, δ Cephei stars, and Miras, as well as many other categories. The underlying mechanism for the variability is generally felt to be due to four different causes: geometric effects, rotation, eruptive processes, and pulsation. In this review the focus will be on pulsation variables and how the theory of stellar evolution can be used to explain how the various regions of variability on the H R diagram are populated. To this end a generalized discussion of the evolutionary behavior of a massive star, an intermediate mass star, and a low mass star will be presented. 19 refs., 1 fig., 1 tab

    2016-12-01

    Full Text Available In many cases, a X¯$\\overline X $ control chart based on a performance variable is used in industrial fields. Typically, the control chart monitors the measurements of a performance variable itself. However, if the performance variable is too costly or impossible to measure, and a less expensive surrogate variable is available, the process may be more efficiently controlled using surrogate variables. In this paper, we present a model for the economic statistical design of a VSI (Variable Sampling Interval X¯$\\overline X $ control chart using a surrogate variable that is linearly correlated with the performance variable. We derive the total average profit model from an economic viewpoint and apply the model to a Very High Temperature Reactor (VHTR nuclear fuel measurement system and derive the optimal result using genetic algorithms. Compared with the control chart based on a performance variable, the proposed model gives a larger expected net income per unit of time in the long-run if the correlation between the performance variable and the surrogate variable is relatively high. The proposed model was confined to the sample mean control chart under the assumption that a single assignable cause occurs according to the Poisson process. However, the model may also be extended to other types of control charts using a single or multiple assignable cause assumptions such as VSS (Variable Sample Size X¯$\\overline X $ control chart, EWMA, CUSUM charts and so on.

We present here the results of a systematic study of all cases of deaths brought to the attention of the Madrid department of the Instituto Nacional de Toxicologia from 1993 to 1995 in which some of these drugs have been found in the cadaveric blood. The cases were divided into three categories: amphetamine and derivatives, amphetamines and alcohol, amphetamines and other drugs. Data on age, sex, clinical symptoms, morphological findings, circumstances of death, when known, and concentration of amphetamine derivatives, alcohol and other drugs in blood are given for each group. The information provided here may prove to be useful for the forensic interpretation of deaths which are directly or indirectly related to abuse of amphetamine derivatives.

    Non-commercial clinical trials may be of great benefit to the patients concerned. The 12th amendment to the German Drug Law (AMG) changed legal liability of the initiators of investigator-initiated clinical trials with extensive consequences for traditional project leaders. The central point under discussion is the sponsor's responsibility according to the AMG. Presently leading management divisions of university hospitals and universities are developing proceedings to assume sponsor responsibility by institutions (institutional sponsorship), which should enable investigator-initiated clinical trials to be conducted according to legal requirements in the future. Detailed problems and special questions can only be resolved in a single-minded fashion, and if necessary political processes should be catalyzed.

  15. Variable screening and ranking using sampling-based sensitivity measures

    International Nuclear Information System (INIS)

    Wu, Y-T.; Mohanty, Sitakanta

    2006-01-01

    This paper presents a methodology for screening insignificant random variables and ranking significant important random variables using sensitivity measures including two cumulative distribution function (CDF)-based and two mean-response based measures. The methodology features (1) using random samples to compute sensitivities and (2) using acceptance limits, derived from the test-of-hypothesis, to classify significant and insignificant random variables. Because no approximation is needed in either the form of the performance functions or the type of continuous distribution functions representing input variables, the sampling-based approach can handle highly nonlinear functions with non-normal variables. The main characteristics and effectiveness of the sampling-based sensitivity measures are investigated using both simple and complex examples. Because the number of samples needed does not depend on the number of variables, the methodology appears to be particularly suitable for problems with large, complex models that have large numbers of random variables but relatively few numbers of significant random variables

    The growth of Internet users enables epidemiological studies to be conducted electronically, representing a promising methodology for data collection. Members of Ethics Committees, Clinical Researchers and Sponsors were interviewed using questionnaires sent over the Internet. Along with the questionnaire, participants received a message explaining the survey and also the informed consent. Returning the questionnaire meant the consent of the participant was given. No incentive was offered; two reminders were sent. The response rate was 21% (124/599), 20% (58/290) and 45% (24/53) respectively for Ethics Committees, Researchers and Sponsors. The percentage of return before the two reminders was about 62%. Reasons for non-response: participant not found, refusal to participate, lack of experience in clinical research or in the therapeutic field. Characteristics of participants: 45% of Ethics Committee participants, 64% of Researchers and 63% of Sponsors were male; mean age (range), respectively: 47 (28-74), 53 (24-72) and 40 (29-65) years. Among Researchers and Sponsors, all respondents had at least a university degree and, in the Ethics Committees group, only two (1.7%) did not have one. Most of the questionnaires in all groups came from the Southeast Region of Brazil, probably reflecting the highest number of clinical trials and research professionals in this region. Despite the potential limitations of a survey done through the Internet, this study led to a response rate similar to what has been observed with other models, efficiency in obtaining responses (speed and quality), convenience for respondents and low cost.

    A linear degenerate odd Poisson bracket (antibracket) realized solely on Grassmann variables is proposed. It is revealed that this bracket has at once three Grassmann-odd nilpotent Δ-like differential operators of the first, second and third orders with respect to the Grassmann derivatives. It is shown that these Δ-like operators, together with the Grassmann-odd nilpotent Casimir function of this bracket, form a finite-dimensional Lie superalgebra

    Full Text Available This paper is a reflective discussion that critically describes the role of the Olympic Intelligence Centre (OIC played in the delivery of a safe and secure London 2012 Olympic and Paralympic Games. In particular, it examines how the OIC worked with the Olympic Sponsors and the wider private sector to provide them with the classified intelligence and information they needed to play their role in the safety and security operation effectively. Issues discussed include the cultural, statutory and systemic challenges that had to be overcome; how relationships were built to allay concerns and build trust and confidence; and the process that was put into place to allow the exchange of classified intelligence that supported the Sponsors and private sector in their operation. It details how the OIC worked with Sponsors to allow them in turn to exchange intelligence they held in their systems with the OIC, thus completing the intelligence cycle, enhancing the security operation. The article concludes with an outline of the lessons learned that were deduced through a reflective process and are offered to practitioners for consideration in future intelligence work involving the private sector.
