    Outpatient discharge decision making in dermatology is poorly understood. To identify the influences on clinicians' thought processes when making discharge decisions in dermatology outpatient clinics. Forty clinicians from 11 National Health Service Trusts in England were interviewed. The interviews were audiorecorded, transcribed, coded and thematically analysed. The mean age of the clinicians was 48.8 years (range 33.0-67.0), 17 (43%) were men and 19 (48%) had > 20 years of clinical experience. One hundred and forty-eight influences were reported, with five main themes: (i) disease-based influences included type of diagnosis (100% of clinicians), guidelines (100%) and treatment needed (100%); (ii) clinician-based influences included the clinician's level of experience (100%), seniority (37%), emotional attitude (95%), 'gut feeling' (25%), personal attitude towards discharge (45%) and level of perception (100%); (iii) patient-based influences included patients' ability to cope with their disease (100%), wishes (70%), quality of life (32%), command of English (40%) and cultural background (25%); (iv) practice-based influences included good primary care (100%), secondary support structure (100%) and clinic capacity pressure (67%); (v) policy-based influences included pressure from hospital managers (57%) and an active discharge policy (7%). Fourteen (9%) influences were potentially inappropriate. This study has identified multiple factors influencing outpatient discharge decision making. This provides the basis for developing evidence-based training to improve discharge decision appropriateness. © 2015 British Association of Dermatologists.

    The influence of the discharge gap between cathode and anode on the discharge stability in a short vacuum arc (SVA) ion source is presented in this paper. Planar cathode and cylindrical hollow anode made of titanium are investigated. There is a great need in present accelerator injection research for SVA source to produce the small deviation of the ion current beam. Current research shows that increasing the short discharge gap can reduce the level of ion current deviation and ion charge deviation from 29% and 31% to 15% and 17%, respectively. A microplasma plume generation mechanism in SVA and scanning electron microscopic results can be used to explain this interesting phenomenon.

    Full Text Available Recently Janda et al. [Phys. Rev. Lett. 108, 248001 (2012] reported an experimental study where it was measured the velocity and volume fraction fields of 1 mm diameter stainless steel beads in the exit of a two-dimensional silo. In that work, they proposed a new expression to predict the flow of granular media in silos which does not explicitly include the particle size as a parameter. Here, we study if effectively, there is not such influence of the particle size in the flux equations as well as investigate any possible effect in the velocity and volume fraction fields. To this end, we have performed high speed motion measurements of these magnitudes in a two-dimensional silo filled with 4 mm diameter beads of stainless steel, the same material than the previous works. A developed tracking program has been implemented to obtain at the same time both, the velocity and volume fraction. The final objective of this work has been to extend and generalize the theoretical framework of Janda et al. for all sizes of particles. We have found that the obtained functionalities are the same than in the 1 mm case, but the exponents and other fitting parameters are different.

    Full Text Available To alleviate increasingly serious water pollution and shortages in developing countries, various kinds of policies have been implemented by local governments. It is vital to quantify and evaluate the performance and potential economic impacts of these policies. This study develops a Computable General Equilibrium (CGE model to simulate the regional economic and environmental effects of discharge fees. Firstly, water resources and water environment factors are separated from the input and output sources of the National Economic Production Department. Secondly, an extended Social Accounting Matrix (SAM of Jiangsu province is developed to simulate various scenarios. By changing values of the discharge fees (increased by 50%, 100% and 150%, three scenarios are simulated to examine their influence on the overall economy and each industry. The simulation results show that an increased fee will have a negative impact on Gross Domestic Product (GDP. However, waste water may be effectively controlled. Also, this study demonstrates that along with the economic costs, the increase of the discharge fee will lead to the upgrading of industrial structures from a situation of heavy pollution to one of light pollution which is beneficial to the sustainable development of the economy and the protection of the environment.

    Based on the wave shape of Marx device at National Key Laboratory of Tunable Laser Technology, Harbin Institute of Technology, the influence of discharge parameters upon the temporal evolvement of capillary discharge produced plasmas conditions and the gain coefficient of 3p-3s transition in Neon-like Ar was simulated. In the simulation, argon with a density of 1.07 x 10 -6 g·cm -3 was filled into a ceramic capillary with an inner diameter of 3.1 mm, the peak of the discharge current pulse was 27.81 kA, and the width of the current pulse was 61.4 ns. The results show that the shorter the pulse rise time is, the higher the gain coefficient is. When the pulse rise time is 20-40 ns, the peak of the current pulse is 25-40 ns, and the current pulse width is 50-70 ns, the higher gain coefficient can be obtained. (authors)

  15. Influence of ion transport on discharge propagation of nanosecond dielectric barrier discharge plasma actuator

    Hua, Weizhuo; Koji, Fukagata

    2017-11-01

    A numerical study has been conducted to understand the streamer formation and propagation of nanosecond pulsed surface dielectric barrier discharge of positive polarity. First we compared the result of different grid configuration to investigate the influence of x and y direction grid spacing on the streamer propagation. The streamer propagation is sensitive to y grid spacing especially at the dielectric surface. The streamer propagation velocity can reach 0.2 cm/ns when the voltage magnitude is 12 kV. A narrow gap was found between the streamer and dielectric barrier, where the plasma density is several orders of magnitude smaller than the streamer region. Analyses on the ion transport in the gap and streamer regions show the different ion transport mechanisms in the two different region. In the gap region, the diffusion of electron toward the dielectric layer decreases the seed electron in the beginning of voltage pulse, resulting that ionization avalanche does not occur. The streamer region is not significantly affected by the diffusion flux toward the dielectric layer, so that ionization avalanche takes place and leads to dramatic increase of plasma density.

  16. Boundary Effect of Planar Glow Dielectric Barrier Discharge and Its Influence on the Discharge Structure

    2015-01-01

    The dielectric barrier discharge (DBD) in the glow regime in neon has been investigated by experiment and two-dimensional (2D) fluid modeling. The discharge was carried out in a planar DBD system with segmented-electrodes driven by square-wave voltage. The results show that the glow DBD originates in the center of the electrode and expands outward to the electrode edge during each half cycle of the voltage, forming a radial structure. The discharge decays firstly in the inner area but sustains longer in the edge area, showing a reversed discharge area. The discharge cannot completely cover the entire electrode surface, but remains a border of non- or weak discharge. The fluid modeling shows a similar result in agreement with the experiments. The simulations indicate that the electric field in the edge area is distorted due to the boundary effect so that the electric field and charge distribution are different from that in the inner part. The distorted field reduces the longitudinal component near the edge and causes the local field to be lower than that in the center, and hence makes the discharge behindhand. It also induces a transverse field that makes the discharge extend radially outward to the edge. The boundary effect plays an important role in the glow DBD structure. (paper)

  17. Influence of Climate Change on River Discharge in Austria

    Directory of Open Access Journals (Sweden)

    Robert A. Goler

    2016-10-01

    Full Text Available The effect of climate change on the river discharge characteristics in four catchment basins within Austria is investigated using a hydrological model. Input for the model are daily climate data generated from three regional climate models (RCMs over the time period 1951–2100 using the A1B emission scenario. Due to the complex terrain of the basins, the climate data has been downscaled to a resolution of 1km×1km$1\\,\\text{km}\\times1\\,\\text{km}$. The hydrological model includes processes such as meltwater from snow and glaciers; surface, subsurface, and groundwater flows; and evapotranspiration. The modelling results show that, although only one RCM exhibits a significant reduction in the mean annual discharge towards the end of the 21st century, all RCMs exhibit significant changes in the seasonal distribution of the discharge. In particular, for basins whose discharge is dependent on water stored as snow, there will be a shift in the time of maximum river discharge to earlier in the year as the snow and ice melt earlier. During the winter months the discharge is forecasted to be higher than at present, which would lead to the number of days of low discharge being reduced. However, the earlier snow melt means that the available water for the summer months will be reduced, leading to lower discharges than present, and thus an increase in the number of low discharge days.

    2010-01-01

    A detailed study of a description method for microdischarges based on the statistical analysis of single discharge bursts is presented and applied for small electrode arrays. As such, the electrical properties derived from the collective behaviour of the current bursts for microdischarges in helium and synthetic air for different pressure levels and variable voltage gradients are elaborately discussed. Motivated by the possible prolongation of the displacement distance of active species and thus the improved development of an atmospheric afterglow in a low frequency discharge, the interaction between high-speed gas flows and microdischarges in small ducts has been approached presenting first results. Intentionally, gases with different discharge mechanisms known as streamer (synthetic air) and Townsend (helium) have been considered. Similar velocity dependences of the discharge behaviour could be observed in both gases. For helium, subsonic channel velocity is sufficient to distinctively alter the discharge characteristics whereas transonic flow is needed to alter those of synthetic air. Subsequently, a simple model is proposed to explain these findings for elevated velocities in a dielectric setup.

    Full Text Available Abstract Background Administrative data are widely used to study health systems and make important health policy decisions. Yet little is known about the influence of coder characteristics on administrative data validity in these studies. Our goal was to describe the relationship between several measures of validity in coded hospital discharge data and 1 coders' volume of coding (≥13,000 vs. Methods This descriptive study examined 6 indicators of face validity in ICD-10 coded discharge records from 4 hospitals in Calgary, Canada between April 2002 and March 2007. Specifically, mean number of coded diagnoses, procedures, complications, Z-codes, and codes ending in 8 or 9 were compared by coding volume and employment status, as well as hospital type. The mean number of diagnoses was also compared across coder characteristics for 6 major conditions of varying complexity. Next, kappa statistics were computed to assess agreement between discharge data and linked chart data reabstracted by nursing chart reviewers. Kappas were compared across coder characteristics. Results 422,618 discharge records were coded by 59 coders during the study period. The mean number of diagnoses per record decreased from 5.2 in 2002/2003 to 3.9 in 2006/2007, while the number of records coded annually increased from 69,613 to 102,842. Coders at the tertiary hospital coded the most diagnoses (5.0 compared with 3.9 and 3.8 at other sites. There was no variation by coder or site characteristics for any other face validity indicator. The mean number of diagnoses increased from 1.5 to 7.9 with increasing complexity of the major diagnosis, but did not vary with coder characteristics. Agreement (kappa between coded data and chart review did not show any consistent pattern with respect to coder characteristics. Conclusions This large study suggests that coder characteristics do not influence the validity of hospital discharge data. Other jurisdictions might benefit from

    2016-09-01

    Atmospheric pressure dielectric barrier discharges (DBDs) sustained in packed bed reactors (PBRs) are being investigated for CO2 removal and conversion of waste gases into higher value compounds. We report on results of a computational investigation of PBR-DBD properties using the plasma hydrodynamics simulator nonPDPSIM with a comparison to experiments. Dielectric beads (rods in 2D) were inserted between two coplanar electrodes, 1 cm apart filled by humid air. A step-pulse of -30 kV was applied to the top electrode. Material properties of the beads (dielectric constant, secondary emission coefficient) and gas properties (photoionization and photo-absorption cross-sections, temperature) were varied. We found that photoionization plays a critical role in the propagation of the discharge through the PBR, as it serves to seed charges in regions of high electric field. Increasing rates of photo-ionization enable increases in the discharge propagation velocity, ionization rates and production of radicals. A transition between DBD-like and arc-like discharges occurs as the radiation mean free path decreases. Increasing the dielectric constant of the beads increased electric fields in the gas, which translated to increased discharge propagation velocity and charge density until ɛ/ɛ0 100. Secondary electron emission coefficient and gas temperature have minimal impacts on the discharge propagation though the latter did affect the production of reactive species.

    The Angra I Nuclear Power Plant makes use of sea-water to condense the steam generated in its secondary circuit. This water, collected from Itaorna bay, is then chlorinated and discharged, with higher temperature, in the Piraquara de Fora bay. Aiming the study of the marine ecosystem, submitted to the effects of the Nuclear Power Plant discharge water, the temperature, residual chlorine, flora and fauna are periodically monitored. Being sensitive to temperature variations and to chemical products, macroscopic algae are also bio-accumulators and primary producers, because of this, they are considered the main link in the food chain and therefore important bio-indicator. This paper shows the variation of species from the brown algae near the discharge of Angra I Nuclear Power Plant. (author)

    Full Text Available A dielectric barrier discharge excited neutral argon (Ar I excimer lamp has been developed and characterised. The aim of this study was to develop an excimer lamp operating at atmospheric pressure that can replace mercury lamps and vacuum equipment used in the sterilisation of medical equipment and in the food industry. The effects of discharge gas pressure, flow rate, excitation frequency and pulse width on the intensity of the Ar I vacuum ultraviolet (VUV emission at 126 nm and near infrared (NIR lines at 750.4 nm and 811.5 nm have been investigated. These three lines were chosen as they represent emissions resulting from de-excitation of excimer states that emit energetic photons with an energy of 9.8 eV. We observed that the intensity of the VUV Ar2* excimer emission at 126 nm increased with increasing gas pressure, but decreased with increasing excitation pulse frequency and pulse width. In contrast, the intensities of the NIR lines decreased with increasing gas pressure and increased with increasing pulse frequency and pulse width. We have demonstrated that energetic VUV photons of 9.8 eV can be efficiently generated in a dielectric barrier discharge in Ar.

    For storm drainages inappropriately connected with sewage, wet weather discharge is a major factor that adversely affects receiving waters. A study of the wet weather influences of rainfall-discharge variables on storm drainages connected with sewage was conducted in the downtown Shanghai area (374 ha). Two indicators, event mean concentration (EMC) and event pollutant load per unit area (EPL), were used to describe the pollution discharge during 20 rain events. The study showed that the total rainfall and discharge volume were important factors that affect the EMCs and EPLs of the chemical oxygen demand, total phosphorus, and especially those of NH 4 + -N. The pollutant concentrations at the beginning of the discharge and the discharge period were also major factors that influence the EMCs of these three pollutants. Regression relationships between the rainfall-discharge variables and discharge volume/ EPLs (R 2 = 0.824-0.981) were stronger than the relationships between the rainfall-discharge variables and EMCs. These regression equations can be considered reliable in the system, with a relative validation error of less than ±10% for the discharge volume, and less than ±20% for the EPLs. The results presented in this paper provide guidance for effectively controlling pollution in similar storm drainages.

  9. The influence of impurities on the discharge behaviour in SPICA

    International Nuclear Information System (INIS)

    Meer, A.F.G. van der.

    1981-10-01

    Discharges in the screw pinch SPICA can be produced in a small range of filling pressures and bias field values. The experimentally observed lower limit of 6 mtorr for the filling pressure is explained by the onset of MHD instabilities and by imperfect implosion at low values of the filling pressure at high values of the bias field. In the accessible parameter regime, discharges can be produced with densities of the order of 5x10 21 m -3 and temperatures between 30 and 80 eV, which show gross stability for 200 μs, albeit not reproducible. In this density and temperature range discharges can easily become dominated by energy losses due to impurity radiation. An investigation of the temperature decay and the impurity concentration shows that, in spite of the quartz liner, this is not the case under normal operating conditions and that the energy containment time is of the order of 200 μs. The temperature decay rate, measured by means of Thomson scattering, is only 0.15 eV/μs, whereas from the intensity ratio of the 15.0 nm 2s 2 S - 3p 2 p 0 and the 103.2 nm 2s 2 S - 2p 2 P 0 OVI emission lines a decay rate of 0.3 eV/μs is derived. From absolute intensity measurements an oxygen concentration is derived. Besides oxygen, also silicon and nitrogen are present in the discharge. The nitrogen concentration that follows from absolute intensity measurements is in fair agreement with estimates based on an analysis of the background gas. The silicon concentration has not been measured directly, but it is estimated to be less than half the oxygen concentration since the wall material is quartz (SiO 2 ) and part of the oxygen originates from the background gas, mainly as a constituent of water vapour

  13. Can a policy program influence policy change? The case of the Swiss EnergieSchweiz program

    International Nuclear Information System (INIS)

    Sager, Fritz; Bürki, Marietta; Luginbühl, Jennifer

    2014-01-01

    This paper investigates the interrelation of policy implementation and policy change by addressing the question of whether and how the Swiss energy program “EnergieSchweiz” influenced policy decisions. We discuss different ways in which a policy program may influence policy change: by negative and positive learning, by coalition building and by policy community building. Respective assumptions are tested in two case studies from the “EnergieSchweiz” program, which was in place from 2000 to 2010. We find that, while the policy program was not critical for the policy change itself, it nevertheless played a role as an agenda setter, as an initiator of learning processes as well as through its policy community. - Highlights: • We investigate how energy policy implementation impacts policy change. • We analyse the Swiss energy program “EnergieSchweiz” in place from 2000 to 2010. • Policy programs alone do not deliver policy change. • But they can influence it by agenda setting and by negative learning. • Expert networks have an influence if there are shared goals

    The properties of a surface barrier discharge in atmospheric-pressure air at different polarities of applied voltage were studied experimentally. The influence of the voltage polarity on the spatial structure of the discharge and the electric field in the discharge plasma was determined by means of spectroscopic measurements. It is found that the energy deposited in the discharge does not depend on the voltage polarity and that discharges of positive polarity are more homogenous and the electric fields in them are higher.

It is generated using center frequency 1 kHz high voltage power supply between two plane parallel electrodes with specific alumina ceramic plates as the dielectric barriers. The discharge characteristics are studied by a measurement of its electrical discharge parameters and observation of its light emission phenomena. The results show that a large single current pulse of about 200 μs duration appearing in each voltage pulse, and its light emission is radially homogeneous and covers the entire surface of the two electrodes. The homogeneous discharge generated is a Townsend discharge during discharge. The influences of applied barrier, its thickness, and surface roughness on the transition of discharge modes are studied. The results show that it is difficult to produce a homogeneous discharge using smooth plates or alumina plate surface roughness Ra material, dielectric thickness, and dielectric surface roughness should be used, and proper applied voltage amplitude and frequency should also be used.

    Full Text Available I the last time many articles were found out discussed about shaft voltage, bearing currents and their influence on lifetime and reliability of electric machines bearings. This is associated with extension of use of static converters for control drives for DC motors feeding in the past and for induction motors feeding from frequency converters in the last time. It is known from our own experiences that not all failures assigned to bearing currents were their real reason and we also know how hardly the mentioned currents can be measured on real machines and how work-intensive and expensive is to detect real reason of the failure on damaged bearing. We will not concern with basics of classical bearing currents in this paper, because they were known and studied in the beginning of the last century but our own investigations will be presented.

    Medicare policy regarding telemedicine reimbursement has changed little since 2000. Many individual states, however, have added telemedicine reimbursement for either Medicaid and/or commercial payers over the same period. Because telemedicine programs must serve patients from all or most payers, it is likely that these state-level policy changes have significant impacts on telemedicine program viability and utilization of services from all payers, not just those services and payers affected directly by state policy. This report explores the impact of two significant state-level policy changes-one expanding Medicaid telemedicine coverage and the other introducing telemedicine parity for commercial payers-on Medicare utilization in the affected states. Medicare claims data from 2011-2013 were examined for states in the Great Lakes region. All valid claims for live interactive telemedicine professional fees were extracted and linked to their states of origin. Allowed encounters and expenditures were calculated in total and on a per 1,000 members per year basis to standardize against changes in the Medicare population by state and year. Medicare telemedicine encounters and professional fee expenditures grew sharply following changes in state Medicaid and commercial payer policy in the examined states. Medicare utilization in Illinois grew by 173% in 2012 (over 2011) following Medicaid coverage expansion, and Medicare utilization in Michigan grew by 118% in 2013 (over 2012) following adoption of telemedicine parity for commercial payers. By contrast, annual Medicare telemedicine utilization growth in surrounding states (in which there were no significant policy changes during these years) varied somewhat but showed no discernible pattern. Although Medicare telemedicine policy has changed little since its inception, changes in state policies with regard to telemedicine reimbursement appear to have significant impacts on the practical viability of telemedicine programs

    Ventilatory after-discharge (sustained elevation of ventilation following stimulus removal) occurs during sleep but not when hypocapnia is present. Genioglossus after-discharge also occurs during sleep, but CO2 effects have not been assessed. The relevance is that postarousal after-discharge may protect against upper airway collapse. This study aimed to determine whether arousal elicits genioglossus after-discharge that persists into sleep, and whether it is influenced by CO2. Twenty-four healthy individuals (6 female) slept with a nasal mask and ventilator. Sleep (EEG, EOG, EMG), ventilation (pneumotachograph), end-tidal CO2 (PETCO2), and intramuscular genioglossus EMG were monitored. NREM eucapnia was determined during 5 minutes on continuous positive airway pressure (4 cmH2O). Inspiratory pressure support was increased until PETCO2 was ≥2 mm Hg below NREM eucapnia. Supplemental CO2 was added to reproduce normocapnia, without changing ventilator settings. Arousals were induced by auditory tones and genioglossus EMG compared during steady-state hypocapnia and normocapnia. Eleven participants (4 female) provided data. Prearousal PETCO2 was less (p sleep. For tonic activity, after-discharge lasted four breaths irrespective of CO2 condition. For peak activity, after-discharge lasted one breath during hypocapnia and 6 breaths during normocapnia. However, when peak activity following the return to sleep was compared between CO2 conditions no individual breath differences were observed. Postarousal genioglossal after-discharge may protect against upper airway collapse during sleep. Steady-state CO2 levels minimally influence postarousal genioglossus after-discharge. © Sleep Research Society 2017. Published by Oxford University Press on behalf of the Sleep Research Society.

    Lyness, Sarah M

    2014-01-01

    Background: Charities exist to pursue a public benefit, whereas corporations serve the interests of their shareholders. The alcohol industry uses corporate social responsibility activities to further its interests in influencing alcohol policy. Many charities also seek to influence alcohol and other policy. The aim of this study was to explore relationships between the alcohol industry and charities in the UK and whether these relationships may be used as a method of influencing alcohol policy. Methods: The charity regulator websites for England and Wales and for Scotland were the main data sources used to identify charities involved in UK alcohol policy making processes and/or funded by the alcohol industry. Results: Five charities were identified that both receive alcohol industry funding and are active in UK alcohol policy processes: Drinkaware; the Robertson Trust; British Institute of Innkeeping; Mentor UK and Addaction. The latter two are the sole remaining non-industry non-governmental members of the controversial responsibility deal alcohol network, from which all other public health interests have resigned. Conclusion: This study raises questions about the extent to which the alcohol industry is using UK charities as vehicles to further their own interests in UK alcohol policy. Mechanisms of industry influence in alcohol policy making globally is an important target for further investigations designed to assist the implementation of evidenced-based policies. PMID:24913316

    The water discharge and sediment load of rivers are changing substantially under the impacts of climate change and human activities, becoming a hot issue in hydro-environmental research. In this study, the water discharge and sediment load in the mainstream and seven tributaries of the Yangtze River were investigated by using long-term hydro-meteorological data from 1953 to 2013. The non-parametric Mann-Kendall test and double mass curve (DMC) were used to detect trends and abrupt change-points in water discharge and sediment load and to quantify the effects of climate change and human activities on water discharge and sediment load. The results are as follows: (1) the water discharge showed a non-significant decreasing trend at most stations except Hukou station. Among these, water discharge at Dongting Lake and the Min River basin shows a significant decreasing trend with average rates of -13.93×10 8 m 3 /year and -1.8×10 8 m 3 /year (PYangtze River. (2) No significant abrupt change-points were detected in the time series of water discharge for all hydrological stations. In contrast, significant abrupt change-points were detected in sediment load, most of these changes appeared in the late 1980s. (3) The water discharge was mainly influenced by precipitation in the Yangtze River basin, whereas sediment load was mainly affected by climate change and human activities; the relative contribution ratios of human activities were above 70% for the Yangtze River. (4) The decrease of sediment load has directly impacted the lower Yangtze River and the delta region. These results will provide a reference for better resource management in the Yangtze River Basin.

This paper takes the congestion charge policy in China, targeted at smog and traffic control, and checks how smog awareness—including smog concerns and perceived smog risks, besides behavioral and policy-related factors—might influence public acceptance of the policy. In this paper, we found both a direct and moderating causal relationship between smog awareness and public acceptance. Based on a sample of 574 valid questionnaires in Beijing and Shanghai in 2016, an ordered logistic regression modeling approach was used to delineate the causality between smog awareness and public acceptance. We found that both smog concerns, such as perceived smog risk, and willingness to pay (WTP were both directly and indirectly positively correlated with public acceptance. These findings imply that policymakers should increase policy fairness with environmental-oriented policy design and should express potential policy effectiveness of the smog controlling policy to citizens to increase their acceptance level.

    A two-dimensional (2D) numerical model of a DC glow discharge in nitrogen is developed for the case when the electric probe is mounted in the discharge gap. Within this model, calculations are performed for the gas pressure of 50 Torr and discharge current densities of 22 and 90 mA cm‑2. A cylindrical probe 1 mm in diameter is located parallel to the anode at a distance of 5 or 10 mm. The probe potential is varied in a wide range relative to the floating potential. Numerical simulations predict the 2D plasma perturbation pattern induced by the electric probe and the influence of the probe on anode layer characteristics. In particular, conditions are determined under which a region with no glow forms in the anode layer.

    The influence is studied of pulse voltage with amplitude 100 kV and duration 100 to 200 ns on the temperature dependence of diamagnetic susceptibility of yttrium ceramics. As a result of the action of spark discharge on the ceramics, the superconducting transition parameters change. As the number of voltage pulses is increased, the diamagnetic susceptibility and the critical temperature determined by it first increase rapidly, then drop slowly. At the same time the transition in the optimum becomes more sharp. In the case of treatment in the air, Tc increases by 15 K and at discharge in liquid nitrogen by 25 K. It is found that the atmospheric air under certain conditions affects the temperature dependence of the diamagnetic susceptibility of HTSC ceramics. Treatment by a high-voltage spark decreases the susceptibility of the ceramics due to atmospheric effects. The highest efficiency of spark treatment is achieved at discharge in liquid nitrogen.

[Subjects and Methods] Sixty patients with femoral trochanteric fractures were investigated retrospectively. Based on the mean period from surgery to discharge (85.6 ± 26.6 days), the patients were divided into two groups: an under-85-day group (range, 29–78 days) and an over-85-day group (87–128 days). Age, gender, fracture type, presence of lesser trochanteric displacement, discharge destination, and walking ability were investigated. The relationship between these factors and the period from surgery to discharge was analyzed with logistic regression analysis. [Results] Age and lesser trochanteric displacement were significantly higher in the over-85-day group, and walking ability before fracture and at discharge were significantly lower in the over-85-day group. Logistic regression analysis showed that lesser trochanteric displacement and age were predictors of the length from surgery to discharge. Lesser trochanteric displacement were observed in 87.5% of these. Immediate displacement after surgery occurred in 57.8% of lesser trochanteric fractures, while 26.3% displaced 1 to 3 weeks after surgery. [Conclusion] This study revealed that lesser trochanteric displacement, higher age, and lower walking ability before fracture and at discharge were associated with longer hospitalizations in patients with femoral trochanteric fractures. Lesser trochanteric displacement were observed in 87.5% of lesser trochanteric fractures. These displacements occurred within 3 weeks after surgery in 84.1% of cases. PMID:29200639

    The aim of this study is to investigate the effect of the intermediate frequency (1-10 kHz) of the sinusoidal driving voltage on the characteristics of a developed surface dielectric barrier discharge (SDBD)-based reactor having spikes on its discharge electrode. Moreover, its influence on the production of ozone and nitrogen oxide byproducts is evaluated. The results show that SDBD is operated in the filamentary mode at all the frequencies. Nevertheless, the pulses of the discharge current at high frequencies are much denser and have higher amplitudes than those at low frequencies. The analysis of the power consumed in the reactor shows that a small portion of the input power is dissipated in the dielectric material of SDBD source, whereas the major part of the power is consumed in the plasma discharge. The results of the ozone production show that higher frequencies have a slightly adverse effect on the ozone production at relatively high energy density values, where the ozone concentration is slightly decreased when the frequency is increased at the same energy density. The temperature of the discharge channels and gas is not a crucial factor for the decomposition of ozone in this reactor, while the results of the measurements of nitrogen oxides characteristics indicate that the formation of NO and NO2 has a significant adverse effect on the production efficiency of ozone due to their oxidation to another nitrogen oxides and their catalytic effect.

    Full Text Available The theme of this study is a distinct examination of the issues regarding health policy, social representations and mass media. The analysis of the mass media influence on the impact of health policy leads to a portrayal of the related programs and the way they are received by citizens through mass media. Owing to the mass media quality to be an indicator of democracy it is very important to study its role in setting people daily agenda considering how it is able to maintain and create trends merely through recurrent messages. The issues frequently conveyed by media industry influences citizens’ interest with regard to community, producing effects on public policy. We must bear in mind that the more persistent in media they are, the more relevant for community this issues will be. The authors of the study put forward a method through which diverse programmes can be analysed. A comparative analysis of mass media and citizens’ social representations and its findings provide information about the influence between them. According to agenda setting theory and many international studies on health policy the authors conclude that mass media institution highly influence the impact of the health policy in health. Moreover, it is important to mention that the impact refers to all the stages of a policy-making: beginning with the problem identification and ending with the evaluation of the implementation process.

    Full Text Available This paper analyzes what channels trade unions in Europe use when trying to influence European Union (EU policies. It compares and contrasts trade unions in different industrial relations regimes with regard to the degree to which they cooperate with different actors to influence EU policies, while also touching on the importance of sector differences and organizational resources. The study is based on survey data collected in 2010–2011 from unions affiliated with the European Trade Union Confederation and from below peak unions in 14 European countries. Results of the survey show that the ‘national route’ is generally the most important for trade unions in influencing EU policies in the sense that this channel is, on average, used to the highest degree. In addition, the survey delineates some important differences between trade unions in different industrial relations regimes with regard to the balance between the national route and different access points in the ‘Brussels route’.

    Full Text Available The Framework Convention of Tobacco Control (FCTC provides a basis for nation states to limit the political effects of tobacco industry philanthropy, yet progress in this area is limited. This paper aims to integrate the findings of previous studies on tobacco industry philanthropy with a new analysis of British American Tobacco's (BAT record of charitable giving to develop a general model of corporate political philanthropy that can be used to facilitate implementation of the FCTC.Analysis of previously confidential industry documents, BAT social and stakeholder dialogue reports, and existing tobacco industry document studies on philanthropy.The analysis identified six broad ways in which tobacco companies have used philanthropy politically: developing constituencies to build support for policy positions and generate third party advocacy; weakening opposing political constituencies; facilitating access and building relationships with policymakers; creating direct leverage with policymakers by providing financial subsidies to specific projects; enhancing the donor's status as a source of credible information; and shaping the tobacco control agenda by shifting thinking on the importance of regulating the market environment for tobacco and the relative risks of smoking for population health. Contemporary BAT social and stakeholder reports contain numerous examples of charitable donations that are likely to be designed to shape the tobacco control agenda, secure access and build constituencies.Tobacco companies' political use of charitable donations underlines the need for tobacco industry philanthropy to be restricted via full implementation of Articles 5.3 and 13 of the FCTC. The model of tobacco industry philanthropy developed in this study can be used by public health advocates to press for implementation of the FCTC and provides a basis for analysing the political effects of charitable giving in other industry sectors which have an impact on

    2013-01-01

    A self-pulsing negative dc discharge in argon generated in a needle-to-plane geometry at open atmosphere is investigated. Additionally, the needle electrode can be surrounded by a quartz capillary. It is shown that the relative position of the capillary end to the needle tip strongly influences the discharge inception and its spatio-temporal dynamics. Without the capillary for the selected working parameters a streamer corona is ignited, but when the capillary surrounds the needle, the transient spark (TS) discharge is ignited after a pre-streamer (PS) occurs. The time between PS and TS discharge depends on the relative capillary end position. The existence of the PS is confirmed by electro-optical characterization. Furthermore, spectrally and spatio-temporally resolved cross-correlation spectroscopy is applied to show the most active region of pre-phase emission activity as indicators for high local electric field strength. The results indicate that with a capillary in place, the necessary energy input of the pre-phase into the system is mainly reduced by additional electrical fields at the capillary edge. Even such a small change as a shift of dielectric surface close to the plasma largely changes the energy balance in the system. (paper)

    2009-09-01

    This paper seeks to consider how nursing as a profession in the United Kingdom is developing its role in shaping and influencing policy using lessons learnt from a policy study tour undertaken in the United States of America and extensive experience as a senior nurse within the government, the health service and more recently within a Professional Organization. The nursing profession faces major changes in health and health care and nurses need to be visible in the public debate about future models of health and health care. This paper critically reviews recent UK and USA literature and policy with relevance to nursing. Strategies that support nurses and nursing to influence policy are in place but more needs to be done to address all levels of nursing in order to find creative solutions that promote and increase the participation of nurses in the political process and health policy. There are lessons to be learnt in the UK from the US nursing experience. These need to be considered in the context of the UK and devolution. Although much has been achieved in positioning nurses and nursing as an influencer in the arena of policy and political decision-making, there is a need for greater co-ordination of action to ensure that nursing is actively supported in influencing and shaping health and health care policy. All leaders and other stakeholders require to play their part in considering how the actions set out in this article can be taken forward and how gaps such as education, fellowship experience and media engagement can be addressed in the future.

    Coastal peatlands are characterized by intense interactions between land and sea, comprising both a submarine discharge of fresh groundwater and inundations of the peatland with seawater. Nutrients and salts can influence the biogeochemical processes both in the shallow marine sediments and in the peatland. The determination of flow direction and quantity of groundwater flow are therefore elementary. Submarine groundwater discharge (SGD) has been reported from several locations in the Baltic. The objective of this study is to quantify the exchange of fresh and brackish water across the shoreline in a coastal peatland in Northeastern Germany, and to assess the influence of a peat layer extending into the Baltic Sea. Below the peatland, a shallow fine sand aquifer differs in depth and is limited downwards by glacial till. Water level and electrical conductivity (EC) are permanently measured in different depths at eight locations in the peatland. First results indicate a general groundwater flow direction towards the sea. Electrical conductivity measurements suggest different permeabilities within the peat layer, depending on its thickness and degradation. Near the beach, EC fluctuates partially during storm events due to seawater intrusion and reverse discharge afterwards. The groundwater flow will be verified with a 3D model considering varying thicknesses of the aquifer. Permanent water level and electrical conductivity readings, meteorological data and hydraulic conductivity from slug tests and grain size analysis are the base for the calibration of the numerical model.

  3. Prototype observation and influencing factors of environmental vibration induced by flood discharge

    2017-01-01

    Full Text Available Due to a wide range of field vibration problems caused by flood discharge at the Xiangjiaba Hydropower Station, vibration characteristics and influencing factors were investigated based on prototype observation. The results indicate that field vibrations caused by flood discharge have distinctive characteristics of constancy, low frequency, small amplitude, and randomness with impact, which significantly differ from the common high-frequency vibration characteristics. Field vibrations have a main frequency of about 0.5–3.0 Hz and the characteristics of long propagation distance and large-scale impact. The vibration of a stilling basin slab runs mainly in the vertical direction. The vibration response of the guide wall perpendicular to the flow is significantly stronger than it is in other directions and decreases linearly downstream along the guide wall. The vibration response of the underground turbine floor is mainly caused by the load of unit operation. Urban environmental vibration has particular distribution characteristics and change patterns, and is greatly affected by discharge, scheduling modes, and geological conditions. Along with the increase of the height of residential buildings, vibration responses show a significant amplification effect. The horizontal and vertical vibrations of the 7th floor are, respectively, about 6 times and 1.5 times stronger than the corresponding vibrations of the 1st floor. The vibration of a large-scale chemical plant presents the combined action of flood discharge and working machines. Meanwhile, it is very difficult to reduce the low-frequency environmental vibrations. Optimization of the discharge scheduling mode is one of the effective measures of reducing the flow impact loads at present. Choosing reasonable dam sites is crucial.

    Sustainability of transportation depends on both behavior and technology. Behavior determines how much of various activities are undertaken; technology determines whether they are harmful to the environment. Policies can influence both: they provide behavior incentives, and they affect technological choices and guide technological change.

    Piezoelectric, dielectric and physicomechanical properties of polymeric piezocomposites on piezoceramics basis are one of the major operational devices of applications. During their application in various devices for a long time can be exposed to various influences for a long time. Piezoelectric, dielectric and strength properties of polymeric piezocomposites strongly depend from the interphase phenomena, and also on charges saved up on border of the unit between components of a composition. Therefore creation the preliminary centers localization for charges in a composition is an actual problem for development effective polymeric piezocomposites. In the given work results of a research preliminary discharge processing's of powders of polymer on strength properties and dielectric characteristics of polymeric compositions on a basis polyvinilidenftorid (PVDF), high density polyethylene and piezoceramic from tetragonal structure are poisoned. Piezoceramic had structure plumbum-zirconate-titanate (PZT). Powders of polymer have been subjected to discharge processing in a quartz glass tube with a diameter 15 mm which walls with 1 mm. It is earthed, from one end and to other end it is connected with high-voltage electrode. Compositions in a volumetric ratio of 90+10 % have been obtained at temperature 435Κ under pressure 15ΜΠa.

    In this work, a model representing partial discharge (PD) behaviour of a spherical cavity within a homogeneous dielectric material has been developed to study the influence of cavity surface charge distribution on the electric field distribution in both the cavity and the material itself. The charge accumulation on the cavity surface after a PD event and charge movement along the cavity wall under the influence of electric field magnitude and direction has been found to affect the electric field distribution in the whole cavity and in the material. This in turn affects the likelihood of any subsequent PD activity in the cavity and the whole sequence of PD events. The model parameters influencing cavity surface charge distribution can be readily identified; they are the cavity surface conductivity, the inception field and the extinction field. Comparison of measurement and simulation results has been undertaken to validate the model.

    The influence of electrical discharge machining (EDM) on the abrasive wear resistance of two WC-10 % w tCo cemented carbides with different carbide grain size has been studied. Different surface finish conditions were evaluated corresponding to sequential EDM as well as grinding and polishing with diamond. The abrasive wear resistance was determined through microscratch measurements using a nano indentation system. Contrary to the results obtained from hardness measurements, this techniques allows to discern tribological differences among the distinct surface finish conditions studied. Finally, the abrasive wear resistance degradation associated with sequential EDM is discussed as a function of microstructure in terms of a damage parameters. (Author) 9 refs

    In March 2013 a state judge invalidated New York City's proposal to ban sales of sugar-sweetened beverages larger than 16 ounces; the case is under appeal. This setback was attributable in part to opposition from the beverage industry and racial/ethnic minority organizations they support. We provide lessons from similar tobacco industry efforts to block policies that reduced smoking prevalence. We offer recommendations that draw on the tobacco control movement's success in thwarting industry influence and promoting public health policies that hold promise to improve population health.

  13. Climate, Companies, and Public Policy: How Transparent Is the Private Sector in Reporting Climate Policy Influence?

    2014-12-01

    To enact effective policies to address climate change, decision makers need both scientific and political support. One major barrier to U.S. climate policy enactment has been the opposition of private sector actors to proposed policies and to climate science itself. Increasingly, the public and investors are holding companies accountable for their actions around climate change—including political activies, affiliations with trade groups, and involvement with climate science. However, this accountability is inhibited by the prominent role that trade associations have played in climate policy debates in recent years. The opaque nature of such groups is problematic, as it inhibits the public from understanding who is obstructing progress on addressing climate change, and in some cases, impedes the public's climate literacy. Voluntary climate reporting can yield some information on companies' climate engagement and demonstrates the need for greater transparency in corporate political activities around climate change. We analyze CDP climate reporting data from 1,824 companies to assess the degree to which corporate actors disclosed their political influence on climate policies through their trade associations. Results demonstrate the limitations of voluntary reporting and the extent to which companies utilize their trade associations to influence climate change policy debates without being held accountable for these positions. Notably, many companies failed to acknowledge their board seat on trade groups with significant climate policy engagement. Of those that did acknowledge their board membership, some claimed not to agree with their trade associations' positions on climate change. These results raise questions about who trade groups are representing when they challenge the science or obstruct policies to address climate change. Recommendations for overcoming this barrier to informed decision making to address climate change will be discussed.

    As a kind of new electric light source, electrodeless discharge lamps are of long life, low mercury and non-stroboscopic light. The lighting effect of electrodeless discharge lamps depends on the radiation efficiency of 253.7 nm resonance spectra line to a large extent. The influence of cold temperature on 253.7 nm resonance spectra line has been studied experimentally by atomic emission spectral analysis. It was found that the radiation efficiency of 253.7 nm resonance spectra line is distributed in a nearly normal fashion with the variation of cold spot temperature, in other words, there is an optimum cold spot temperature for an electrodeless discharge lamp. At last, the results of experiments were analyzed through gas discharge theory, which offers guidance to the improvement of lighting effect for electrodeless discharge lamps.

    To reveal the variation of microbial community functions during water filtration process in river sediments, which has been utilized widely in natural water treatment systems, this study investigates the influence of municipal wastewater discharge to streams on the phylotype and metabolic potential of the microbiome in upstream and particularly various depths of downstream river sediments. Cluster analyses based on both microbial phylogenetic and functional data collectively revealed that shallow upstream sediments grouped with those from deeper subsurface downstream regions. These sediment samples were distinct from those found in shallow downstream sediments. Functional genes associated with carbohydrate, xenobiotic, and certain amino acid metabolisms were overrepresented in upstream and deep downstream samples. In contrast, the more immediate contact with wastewater discharge in shallow downstream samples resulted in an increase in the relative abundance of genes associated with nitrogen, sulfur, purine and pyrimidine metabolisms, as well as restriction-modification systems. More diverse bacterial phyla were associated with upstream and deep downstream sediments, mainly including Actinobacteria, Planctomycetes, and Firmicutes. In contrast, in shallow downstream sediments, genera affiliated with Betaproteobacteria and Gammaproteobacteria were enriched with putative functions that included ammonia and sulfur oxidation, polyphosphate accumulation, and methylotrophic bacteria. Collectively, these results highlight the enhanced capabilities of microbial communities residing in deeper stream sediments for the transformation of water contaminants and thus provide a foundation for better design of natural water treatment systems to further improve the removal of contaminants.

    In obtaining the best quality of engineering components, the quality of machined parts surface plays an important role. It improves the fatigue strength, wear resistance, and corrosion of workpiece. This paper investigates the effects of wire electrical discharge machining (WEDM) process parameters on surface roughness of stainless steel using distilled water as dielectric fluid and brass wire as tool electrode. The parameters selected are voltage open, wire speed, wire tension, voltage gap, and off time. Empirical model was developed for the estimation of surface roughness. The analysis revealed that off time has a major influence on surface roughness. The optimum machining parameters for minimum surface roughness were found to be at a 10 V open voltage, 2.84 μs off time, 12 m/min wire speed, 6.3 N wire tension, and 54.91 V voltage gap.

    One of the most common methods of carbon nanotubes (CNTs) synthesis is application of an electric-arc plasma. However, the final product in the form of cathode deposit is composed of carbon nanotubes and a variety of carbon impurities. An assay of carbon nanotubes produced in arc discharge systems available on the market shows that commercial cathode deposits contain about 10% CNTs. Given that the quality of the final product depends on carbon-plasma jet parameters, it is possible to increase the yield of the synthesis by plasma jet control. Most of the carbon nanotubes are multiwall carbon nanotubes (MWCNTs). It was observed that the addition of catalysts significantly changes the plasma composition, effective ionization potential, the arc channel conductance, and in effect temperature of the arc and carbon elements flux. This paper focuses on the influence of metal components on plasma-jet forming containing carbon nanotubes cathode deposit. The plasma jet temperature control system is presented.

    Physical and chemical properties of wool surface significantly affect the absorbency, rate of dye bath exhaustion and fixation of the industrial dyes. Hence, surface modification is a necessary operation prior to coloration process in wool wet processing industries. Plasma treatment is an effective alternative for physiochemical modification of wool surface. However, optimum processing parameters to get the expected modification are still under investigation, hence this technology is still under development in the wool wet processing industries. Therefore, in this paper, treatment parameters with the help of simple dielectric barrier discharge plasma reactor and air as a plasma gas, which could be a promising combination for treatment of wool substrate at industrial scale were schematically studied, and their influence on the water absorbency, mechanical, and dyeing properties of twill woven wool fabric samples are reported. It is expected that the results will assist to the wool coloration industries to improve the dyeing processes.

  6. Contaminant transport modelling in tidal influenced water body for low level liquid waste discharge out

    Low level liquid waste is generated from nuclear reactor operation and reprocessing of spent fuel. This waste is discharged into the water body after removing bulk of its radioactivity. Dispersion of contaminant mainly depends on location of outfall and hydrodynamics of water body. For radiological impact assessment, in most of the analytical formulations, source term is taken as continuous release. However, this may not be always true as the water level is influenced by tidal movement and the selected outfall may come under intertidal zone in due course of the tidal cycle. To understand these phenomena, a case study has been carried out to evaluate hydrodynamic characteristics and dilution potential of outfall located in inter-tidal zone using numerical modelling

  7. Influence of grid resolution in fluid-model simulation of nanosecond dielectric barrier discharge plasma actuator

    2018-04-01

    Two-dimensional numerical simulation of a surface dielectric barrier discharge (SDBD) plasma actuator, driven by a nanosecond voltage pulse, is conducted. A special focus is laid upon the influence of grid resolution on the computational result. It is found that the computational result is not very sensitive to the streamwise grid spacing, whereas the wall-normal grid spacing has a critical influence. In particular, the computed propagation velocity changes discontinuously around the wall-normal grid spacing about 2 μm due to a qualitative change of discharge structure. The present result suggests that a computational grid finer than that was used in most of previous studies is required to correctly capture the structure and dynamics of streamer: when a positive nanosecond voltage pulse is applied to the upper electrode, a streamer forms in the vicinity of upper electrode and propagates along the dielectric surface with a maximum propagation velocity of 2 × 108 cm/s, and a gap with low electron and ion density (i.e., plasma sheath) exists between the streamer and dielectric surface. Difference between the results obtained using the finer and the coarser grid is discussed in detail in terms of the electron transport at a position near the surface. When the finer grid is used, the low electron density near the surface is caused by the absence of ionization avalanche: in that region, the electrons generated by ionization is compensated by drift-diffusion flux. In contrast, when the coarser grid is used, underestimated drift-diffusion flux cannot compensate the electrons generated by ionization, and it leads to an incorrect increase of electron density.

  8. Opportunities for scientists to influence policy: When does radiation metrology matter in development of national policy?

    International Nuclear Information System (INIS)

    Coursey, Bert M.

    2014-01-01

    Accurate measurements of radiation and radioactivity rarely rise to the level of national policy. The things that matter most to ordinary citizens do not normally include questions of science and technology. Citizens are more often concerned with issues close to home relating to commerce, health, safety, security and the environment. When questions of confidence in measurements arise, they are first directed to the ministry that has responsibilities in that area. When the required uncertainty in field measurements challenges the capability of the regulatory authorities, the National Metrology Institute may be asked to develop transfer standards to enhance the capabilities of the ministry with the mission lead. In this paper, we will consider eight instances over the past nine decades in which questions in radiation and radionuclide metrology in the US did rise to the level that they influenced decisions on national policy. These eight examples share some common threads. Radioactivity and ionizing radiation are useful tools in many disciplines, but can often represent potential or perceived threats to health and public safety. When unforeseen applications of radiation arise, or when environmental radioactivity from natural and man-made sources presents a possible health hazard, the radiation metrologists may be called upon to provide the technical underpinning for policy development. - Highlights: • We review instances in which accurate measurements of radiation influence policy. • Heads of state rely on senior science advisors to frame policy decisions. • Metrologists support federal agencies that have mission leads in different fields. • Metrologists are called on when other agencies lack requisite expertise. • Radionuclide metrologists must recognize and accept challenges

    Researches results of the characteristics of the RF discharge jet of low pressure and the discharge influence on the surface modification of high speed and structural steels are introduced in the article. Gas dynamics, power and energy parameters of the RF low pressure discharge flow in the discharge chamber and the electrode gap are studied in the presence of the materials. Plasma flow rate, discharge power, the concentration of electrons, the density of RF power, the ion current density, and the energy of the ions bombarding the surface materials are considered for the definition of basic properties crucial for the process of surface modification of materials as they were put in the plasma jet. The influence of the workpiece and effect of products complex configuration on the RF discharge jet of low pressure is defined. The correlation of the input parameters of the plasma unit on the characteristics of the discharge is established.

    Although concerns have historically been raised about the influence of external donors on health policy process in recipient countries, remarkably few studies have investigated perspectives and experiences of domestic policymakers and advisers. This study examines donor influence at different stages of the health policy process (priority setting, policy formulation, policy implementation and monitoring and evaluation) in two aid-dependent LMICs, Cambodia and Pakistan. It identifies mechanisms through which asymmetries in influence between donors and domestic policy actors emerge. We conducted 24 key informant interviews-14 in Pakistan and 10 in Cambodia-with high-level decision-makers who inform or authorize health priority setting, allocate resources and/or are responsible for policy implementation, identifying three routes of influence: financial resources, technical expertise and indirect financial and political incentives. We used both inductive and deductive approaches to analyse the data. Our findings indicate that different routes of influence emerged depending on the stage of the policy process. Control of financial resources was the most commonly identified route by which donors influenced priority setting and policy implementation. Greater (perceived) technical expertise played an important role in donor influence at the policy formulation stage. Donors' power in influencing decisions, particularly during the final (monitoring and evaluation) stage of the policy process, was mediated by their ability to control indirect financial and political incentives as well as direct control of financial resources. This study thus helps unpack the nuances of donor influence over health policymaking in these settings, and can potentially indicate areas that require attention to increase the ownership of domestic actors of their countries' health policy processes. © The Author(s) 2017.

  11. The Influence of Relative Humidity on Dielectric Barrier Discharge Plasma Flow Control Actuator Performance

    2012-11-01

    Dielectric barrier discharge (DBD) plasma actuators possess numerous advantages for flow control applications and have been the focus of several previous studies. Most work has been performed in relatively pristine laboratory settings. In actual flow control applications, however, it is essential to assess the impact of various environmental influences on actuator performance. As a first effort toward assessing a broad range of environmental effects on DBD actuator performance, the influence of relative humidity (RH) is considered. Actuator performance is quantified by force balance measurements of reactive thrust while RH is systematically varied via an ultrasonic humidifier. The DBD plasma actuator assembly, force balance, and ultrasonic humidifier are all contained inside a large, closed test chamber instrumented with RH and temperature sensors in order to accurately estimate the average RH at the actuator. Measurements of DBD actuator thrust as a function of RH for several different applied voltage regimes and dielectric materials and thicknesses are presented. Based on these results, several important design recommendations are made. This work was supported by Innovative Technology Applications Company (ITAC), LLC under a Small Business Innovation Research (SBIR) Phase II Contract No. N00014-11-C-0267 issued by the U.S. Department of the Navy.

    2012-01-01

    Interest in plasma actuators as active flow control devices is growing rapidly due to their lack of mechanical parts, light weight and high response frequency. Although the flow induced by these actuators has received much attention, the effect that the external flow has on the performance of the actuator itself must also be considered, especially the influence of unsteady high-speed flows which are fast becoming a norm in the operating flight envelopes. The primary objective of this study is to examine the characteristics of a dielectric barrier discharge (DBD) plasma actuator when exposed to an unsteady flow generated by a shock tube. This type of flow, which is often used in different studies, contains a range of flow regimes from sudden pressure and density changes to relatively uniform high-speed flow regions. A small circular shock tube is employed along with the schlieren photography technique to visualize the flow. The voltage and current traces of the plasma actuator are monitored throughout, and using the well-established shock tube theory the change in the actuator characteristics are related to the physical processes which occur inside the shock tube. The results show that not only is the shear layer outside of the shock tube affected by the plasma but the passage of the shock front and high-speed flow behind it also greatly influences the properties of the plasma.

    The effects of wetlands on hydrology, water quality, and wildlife habitat are internationally recognized. Protecting the remaining wetlands is one of the most important environmental issues in many countries. However wetlands in Japan have been gradually shrinking due to agricultural development and urbanization, which generally lowers the groundwater level and introduces suspended sediment and sediment-associated nutrients into wetlands. We examined the influences of channelization on discharge of suspended sediment and wetland vegetation in Hokkaido, northern Japan. The impact of river channelization was confirmed not only by the sediment budgets but also by river aggradation or degradation after the channelization and by the resultant vegetational changes. The budgets of suspended sediment demonstrated that wash load was the predominant component accounting for 95% of the total suspended load delivered into the wetland. This suspended sediment was primarily transported into the wetland by flooding associated with heavy rainfall. Twenty-three percent of the wash load and 63% of the suspended bed material load were deposited in the channelized reach, which produced aggradation of about 2 m at the end of the reach. A shorting of the length of the channel, due to channelization of a meandering river, steepened the slope and enhanced the stream power to transport sediment. This steepening shifted the depositional zones of fine sediment 5 km downstream and aggraded the riverbed. Development of the watershed may increase not only the water discharge but also the amount of suspended sediments. The aggradation reduced the carrying capacity of the channel and caused sediment ladened water to flood over the wetlands. The fine sediment accumulated on the wetlands gradually altered the edaphic conditions and wetland vegetation. A low percentage (10 to 15%) of organic contents of wetlands' soil is more evidence indicating that the present condition is far different from

  14. The influence of chamfering and corner radiusing on the discharge coefficient of rotating axial orifices

    The effects of chamfering and corner radiusing on the discharge coefficient of rotating axial orifices are presented in this paper. Both experimental and CFD results show that chamfering and corner radiusing improve the discharge coefficient of rotating orifices. For non-inclined rotating orifices, the discharge coefficient reduces with increasing speed, but chamfered and radiused orifices manage to have higher discharge coefficient (C d ) than the straight edge orifices. Comparing between chamfering and corner radiusing, the radiused corner orifice has the highest C d at every rotational speed. This is because the inlet radius helps guiding the flow into the orifice and avoiding flow separation at the inlet.

    The influence of nitrogen oxides NO and NO 2 on the specific input energy (SIE) and the time behaviour of singlet delta oxygen (SDO) luminescence excited by a pulsed e-beam sustained discharge in oxygen were experimentally and theoretically studied. NO and NO 2 addition into oxygen results in a small increase and decrease in the SIE, respectively, the latter being connected with a large energy of electron affinity to NO 2 . The addition of 0.1-0.3% nitrogen oxides was experimentally and theoretically demonstrated to result in a notable enhancement of the SDO lifetime, which is related to a decrease in the atomic oxygen concentration in afterglow. It was experimentally demonstrated that to get a high SDO concentration at the gas pressure 30-60 Torr for a time interval of less than ∼0.5 s one needs to add not less than 0.2% nitrogen oxides into oxygen. The temperature dependence of the relaxation constant for SDO quenching by unexcited oxygen was estimated by using experimental data on the time behaviour of SDO luminescence.

    To ascertain the influence of the duration of the 'interval loading-discharging embryos' (ILDE) on the results of embryo transfer. The population under study consisted of 450 consecutive fresh embryo transfers. ILDE was measured in all transfers. Pregnancy and implantation rates were analyzed. Conceptional cycles had a lower (mean +/- SD) ILDE than non conceptional cycles (53.5 +/- 43.6 s vs 63.7 +/- 49.3). When only easy transfers--defined as those not requiring cervical tenaculum--were considered, similar differences were observed. The following pregnancy rates were obtained according ILDE duration: 38.9% (ILDE ILDE 31-60), 31.6% (ILDE 61-120) and 19.1% (ILDE > 120) (P ILDE duration is a prognostic factor of pregnancy rate and of implantation rate in IVF. The longer the ILDE duration, the lower the pregnancy and implantation rates. The decrease in pregnancy and implantation rates is gradual until an ILDE of 120 s, and decreases sharply afterwards. It is recommended to speed up the embryo transfer process, wherever possible. ILDE > 120 s carries a poor prognosis and should, when possible, be avoided.

    Engineering ceramics have been widely used in modern industry for their excellent physical and mechanical properties, and they are difficult to machine owing to their high hardness and brittleness. Electrical discharge machining (EDM) is the appropriate process for machining engineering ceramics provided they are electrically conducting. However, the electrical resistivity of the popular engineering ceramics is higher, and there has been no research on the relationship between the EDM parameters and the electrical resistivity of the engineering ceramics. This paper investigates the effects of the electrical resistivity and EDM parameters such as tool polarity, pulse interval, and electrode material, on the ZnO/Al2O3 ceramic's EDM performance, in terms of the material removal rate (MRR), electrode wear ratio (EWR), and surface roughness (SR). The results show that the electrical resistivity and the EDM parameters have the great influence on the EDM performance. The ZnO/Al2O3 ceramic with the electrical resistivity up to 3410 Ω·cm can be effectively machined by EDM with the copper electrode, the negative tool polarity, and the shorter pulse interval. Under most machining conditions, the MRR increases, and the SR decreases with the decrease of electrical resistivity. Moreover, the tool polarity, and pulse interval affect the EWR, respectively, and the electrical resistivity and electrode material have a combined effect on the EWR. Furthermore, the EDM performance of ZnO/Al2O3 ceramic with the electrical resistivity higher than 687 Ω·cm is obviously different from that with the electrical resistivity lower than 687 Ω·cm, when the electrode material changes. The microstructure character analysis of the machined ZnO/Al2O3 ceramic surface shows that the ZnO/Al2O3 ceramic is removed by melting, evaporation and thermal spalling, and the material from the working fluid and the graphite electrode can transfer to the workpiece surface during electrical discharge

    Kombolcha, a city in Ethiopia, exemplifies the challenges and problems of the sub-Saharan countries where industrialization is growing fast but monitoring resources are poor and information on pollution unknown. This study monitored metals Cr, Cu, Zn, and Pb concentrations in five factories' effluents, and in the effluent mixing zones of two rivers receiving discharges during the rainy seasons of 2013 and 2014. The results indicate that median concentrations of Cr in the tannery effluents and Zn in the steel processing effluents were as high as 26,600 and 155,750 µg/L, respectively, much exceeding both the USEPA and Ethiopian emission guidelines. Cu concentrations were low in all effluents. Pb concentrations were high in the tannery effluent, but did not exceed emission guidelines. As expected, no metal emission guidelines were exceeded for the brewery, textile and meat processing effluents. Median Cr and Zn concentrations in the Leyole river in the effluent mixing zones downstream of the tannery and steel processing plant increased by factors of 52 (2660 compared with 51 µg Cr/L) and 5 (520 compared with 110 µg Zn/L), respectively, compared with stations further upstream. This poses substantial ecological risks downstream. Comparison with emission guidelines indicates poor environmental management by industries and regulating institutions. Despite appropriate legislation, no clear measures have yet been taken to control industrial discharges, with apparent mismatch between environmental enforcement and investment policies. Effluent management, treatment technologies and operational capacity of environmental institutions were identified as key improvement areas to adopt progressive sustainable development.

    A surface Dielectric Barrier Discharge (DBD) reactor was utilized to degrade phenol in water. Different power supplies applied to the DBD reactor affect the discharge modes, the formation of chemically active species and thus the removal efficiency of pollutants. It is thus important to select an optimized power supply for the DBD reactor. In this paper, the influence of the types of power supplies including alternate current (AC) and bipolar pulsed power supply on the ozone generation in a surface discharge reactor was measured. It was found that compared with bipolar pulsed power supply, higher energy efficiency of O 3 generation was obtained when DBD reactor was supplied with 50Hz AC power supply. The highest O 3 generation was approximate 4 mg kJ −1 ; moreover, COD removal efficiency of phenol wastewater reached 52.3% after 3 h treatment under an AC peak voltage of 2.6 kV.

    In order to examine the influence of discharge from different rivers from peninsular India and urban sewage on intensity and dissemination of heterotrophic, indicator and pathogenic bacteria, a study was carried out during peak discharge period along coastal Bay of Bengal. The coastal Bay received freshwater inputs from the river Ganges while Godavari and Krishna contributed to the south. Contrasting difference in salinity, temperature, nutrients and organic matter was observed between north and south east coast of India. The highest heterotrophic, indicator and pathogenic bacterial abundance was observed in the central coastal Bay that received urban sewage from the major city. Intensity and dissemination of heterotrophic, indicator and pathogenic bacteria displayed linear relation with magnitude of discharge. The coliform load was observed up to 100km from the coast suggesting that marine waters were polluted during the monsoon season and its impact on the ecosystem needs further studies.

    Bifurcations represent key morphological nodes within the channel networks of anabranching and braided fluvial channels, playing an important role in controlling local bed morphology, the routing of sediment and water, and defining the stability of the downstream reaches. Herein, we detail field observations of the three-dimensional flow structure, bed morphological changes and partitioning of both flow discharge and suspended sediment through a large diffluence-confluence unit on the Mekong River, Cambodia, across a range of flow stages (from 13,500 m3 s-1 to 27,000 m3 s-1) over the monsoonal flood-pulse cycle. We show that the discharge asymmetry (a measure of the disparity between discharges distributed down the left and right branches of the bifurcation) varies with flow discharge and that the influence of upstream curvature-induced cross-stream water surface slope and bed morphological changes are first-order controls in modulating the asymmetry in bifurcation discharge. Flow discharge is shown to play a key role in defining the morphodynamics of the diffluence-confluence unit downstream of the bifurcation. Our data show that during high flows (Q 27,000 m3 s-1), the downstream island complex acts as a net sink of suspended sediment (with 2600 kg s-1 being deposited between the diffluence and confluence), whereas during lower flows, on both the rising and falling limbs of the flood wave, the sediment balance is in quasi-equilibrium. We propose, therefore, that the long term stability of the bifurcation, as well as the larger channel planform and morphology of the diffluence-confluence unit, is therefore controlled by annual monsoonal flood pulses and the associated variations in discharge.

    In this paper, the plasma electric conductivity and the channel radius for high-pressure mercury arc discharge are calculated. The examined model emphasizes some correlations between various external parameters (current intensity, silicon tube diameter and working pressure) and the channel discharge radius. After model validation, the temperature distribution in the discharge zone is obtained and then the electrons and ions distribution, the electric carriers mobility and the electric conductivity for different lamp characteristics are calculated. The applied numerical simulation shows a linear increase of the channel radius with the tube radius Rw increasing, and a very week pressure dependence (in the range 0.5 - 5 atm.)

    Full Text Available Human vulnerability to heat varies at a range of spatial scales, especially within cities where there can be noticeable intra-urban differences in heat risk factors. Mapping and visualizing intra-urban heat vulnerability offers opportunities for presenting information to support decision-making. For example the visualization of the spatial variation of heat vulnerability has the potential to enable local governments to identify hot spots of vulnerability and allocate resources and increase assistance to people in areas of greatest need. Recently there has been a proliferation of heat vulnerability mapping studies, all of which, to varying degrees, justify the process of vulnerability mapping in a policy context. However, to date, there has not been a systematic review of the extent to which the results of vulnerability mapping studies have been applied in decision-making. Accordingly we undertook a comprehensive review of 37 recently published papers that use geospatial techniques for assessing human vulnerability to heat. In addition, we conducted an anonymous survey of the lead authors of the 37 papers in order to establish the level of interaction between the researchers as science information producers and local authorities as information users. Both paper review and author survey results show that heat vulnerability mapping has been used in an attempt to communicate policy recommendations, raise awareness and induce institutional networking and learning, but has not as yet had a substantive influence on policymaking or preventive action.

    The influences of electron discharge and magnetic field on calcium carbonate (CaCO{sub 3}) precipitation in water have been successfully investigated. The study used three pairs of magnetic field 0.1 T whilst the electron discharge was generated from television flyback transformer type BW00607 and stainless steel SUS 304 as an electrode. The water sample with an initial condition of 230 mg/L placed in the reactor with flow rate 375 mL/minutes, result showed that the electron discharge can be reduced contain of calcium carbonate the water sample around 17.39% within 2 hours. Meanwhile for the same long period of treatment and flow rate, around 56.69% from initial condition of 520 mg/L of calcium carbonate in the water sample can be achieved by three pairs of magnetic field 0.1 T. When the combination of three pairs of magnetic field 0.1 T and the electron discharge used for treatment, the result showed that the combination of electron discharge and magnetic field methods can be used to precipitate calcium carbonate in the water sample 300 mg/L around 76.66% for 2 hours of treatment. The study then investigated the influence of the polar position of the magnetic field on calcium carbonate precipitation. Two positions of magnetic field were tested namely the system with alternated polar magnetics and the system without inversion of the polar magnetics. The influence of the polar position showed that the percentage reduction in levels of calcium carbonate in the water sample (360 mg/L) is significant different. Result showed that the system without inversion of the polar magnetics is generally lower than the system with alternated polar magnetics, with reduction level at 30.55 and 57.69%, respectively.

    In this study, three different dielectric barrier discharges, based on the same setup and run with the same power supply, are characterized by emission spectroscopy with regards to the reduced electrical field strength, and the rotational, vibrational and electron temperature. To compare discharges common for the treatment on wood, a coplanar surface barrier discharge, a direct dielectric barrier discharge and a jet system/remote plasma are chosen. To minimize influences due to the setups or power, the discharges are realized with the same electrodes and power supply and normalized to the same power. To evaluate the efficiency of the different discharges and the influence on treated materials, the surface free energy is determined on a maple wood, high density fiberboard and wood plastic composite. The influence is measured depending on the treatment time, with the highest impact in the time of 5 s. (paper)

    Full Text Available Nowadays, learning more about influence groups on public policy making is one of most important subjects of management science. Governments are the primary sources for public policy making but influenced groups participate indirectly and while they remain out of power, they put pressure on many decisions. Some of participants in public policy making are not influenced groups but mostly, due to their participation in policy public making matter are called influenced groups. This research, from practical research purpose and method view, is a descriptive research and survey branch. The study investigates the effect of university based Iranian Sociological Association on public policy making. The study designs a questionnaire in Likert scale and distributes it among some experts. The results of our survey indicate that that Iranian Sociological Association could influence on public policy making through elite and prominent leaders, self-knowledge and information, elective campaigns, stimulation and connecting with people and other groups.

    Full Text Available A study was conducted on the impact of forest clearance on discharge from newly established Hopea odorata plantations catchment (14.4 ha. The stands were two years old when this study commenced in year 2006 and the data collection was carried out for two years. The forested catchment (C3 was clear-cut during the preparation of the forest plantation and catchment C1 was left undisturbed. Discharge and rainfall were measured continuously for two years. The discharge measured from years 1997 to 2003 was used also to determine the water yield before and after forest clear-cut. This study showed that the plantation catchment is more responsive to storm with higher total water yield than in the forested catchment. The effect of forest clear cutting to discharge was clearly shown by the increment in the amount following the clear-cut activities and time taken for the recovery of the discharge back to its original state was almost three years. The peak discharge in C3 also was affected in which the biggest change was obtained during the forest clear-cutting period compared with during calibration and after clearing periods. This study is useful as basis for improving the existing guidelines on forest plantation establishment.

    Full Text Available Dynamics of fiscal policy, more specific rise in fiscal pressure, increase which can be obtained either through enforcing one or more taxes, or by augmenting at least a tax, has a powerful impact on output management – visible, in the first place, in the realm of output size. But, not only output size will vary, after an increase in fiscal pressure, at least because output management is dealing with more than issue of producing a certain quantity of products, material or not, goods and/or services. Products are made for selling, but selling is impossible but through price and with a price; price is an essential economic variable, both in microeconomic and macroeconomic spheres. Thus, on one side rise in fiscal pressure determines, at least in short term, and, of course, if producers pay, or even support, a tax, be it newly enforced or (newly augmented, a rise of prices for sold products, and, on the other side, this results in a variation in output size, e.g. a reduced output volume, but, though, not in a linear trend. The dynamics, in this case of economic mechanism whose yield is a reduced volume of goods and/or services, in not linear, because essential are, too, the characteristics of products, from which effects of demand price elasticity and offer price elasticity influence significantly, in this framework, output management.

  17. Influence of an additional ballast volume on a pulsed ICP discharge

    2007-01-01

    A spatial and temporal numerical simulation has been carried out of a pulsed (100% modulated), rf inductively coupled plasma discharge in argon, connected to an additional (ballast) diffusion chamber of much larger volume. It is demonstrated that during the active phase, the presence of the large ballast volume has a small impact on the parameters of the plasma in the smaller discharge chamber. In this case the plasma parameters in the discharge chamber can be estimated separately from the diffusion chamber by a standard method using the characteristic ambipolar diffusion time (for example, using a global model). However, during the afterglow phase, the situation is changed significantly. In the afterglow, the densities of charged particles in the discharge chamber become lower than in the large ballast chamber due to more rapid diffusion loss. As a result, the reverse of the active phase situation occurs, namely, the plasma does not flow from the small to the large chamber, but in the opposite direction, from diffusive to discharge volume, and both the plasma density gradient and the self-consistent ambipolar electric field in the small chamber change directions. This phenomenon leads to new effects in the discharge volume, in particular a decreasing rate of decay of densities of charged particles and electron temperature. Thus, in the afterglow the presence of a large additional ballast volume has a significant impact on the plasma transport. In this case, a simple treatment of the plasma in the discharge chamber in the framework of a spatially averaged model (for example, the global model) is inadequate

    Gagnon, François; Bellefleur, Olivier

    2014-07-11

    The healthy public policy movement rests on the belief that a range of public policies should be at least partly informed by evidence demonstrating the positive effects of these policies on population health, health inequalities and their determinants. In order to address certain difficulties that the movement faces, knowledge produced in various scientific disciplines regarding public policies may provide some valuable guidance. In this short commentary, we examine how knowledge from the scientific disciplines investigating public policies makes it possible to address two difficulties in the development of healthy public policies: 1) adequately anticipating the effects of public policies, and 2) assessing the political viability of the policies being promoted. Since urban traffic policies are of interest to most of the other contributors to this supplement, we use examples from this field to illustrate some of our points.

  19. Streambed scour of salmon spawning habitat in a regulated river influenced by management of peak discharge

    2017-01-01

    In the Pacific Northwest of the United States, salmon eggs incubating within streambed gravels are susceptible to scour during floods. The threat to egg-to-fry survival by streambed scour is mitigated, in part, by the adaptation of salmon to bury their eggs below the typical depth of scour. In regulated rivers globally, we suggest that water managers consider the effect of dam operations on scour and its impacts on species dependent on benthic habitats.We instrumented salmon-spawning habitat with accelerometer scour monitors (ASMs) at 73 locations in 11 reaches of the Cedar River in western Washington State of the United States from Autumn 2013 through the Spring of 2014. The timing of scour was related to the discharge measured at a nearby gage and compared to previously published ASM data at 26 locations in two reaches of the Cedar River collected between Autumn 2010 and Spring 2011.Thirteen percent of the recovered ASMs recorded scour during a peak-discharge event in March 2014 (2-to 3-year recurrence interval) compared to 71% of the recovered ASMs during a higher peak-discharge event in January 2011 (10-year recurrence interval). Of the 23 locations where ASMs recorded scour during the 2011 and 2014 deployments, 35% had scour when the discharge was ≤87.3 m3/s (3,082 ft3/s) (2-year recurrence interval discharge) with 13% recording scour at or below the 62.3 m3/s (2,200 ft3/s) operational threshold for peak-discharge management during the incubation of salmon eggs.Scour to the depth of salmon egg pockets was limited during peak discharges with frequent (1.25-year or less) recurrence intervals, which managers can regulate through dam operations on the Cedar River. Pairing novel measurements of the timing of streambed scour with discharge data allows the development of peak-discharge management strategies that protect salmon eggs incubating within streambed gravels during floods.

When the gaps of split targets reached a certain value, the peak values of the discharge current decreased again. Meanwhile, the gaps among high and low-potential targets was 5mm, the peak value of the discharge current was the smallest. With the increasing of the gaps among the split targets, a primary discharge duration also increased. However, when the gaps among the split targets were greater than 5mm, increasing trend of discharge duration would slow down. When the gaps among the split targets were greater than 7mm, there was a secondary discharge phenomenon, and the physical explanations were given about the influence of different gaps among the split targets on the discharge effects created by hypervelocity impact.

    A 3-D, time-dependent, baroclinic, hydrodynamic and salinity model was implemented and applied to the Danshuei River estuarine system and the adjacent coastal sea in Taiwan. The model forcing functions consist of tidal elevations along the open boundaries and freshwater inflows from the main stream and major tributaries in the Danshuei River estuarine system. The bottom friction coefficient was adjusted to achieve model calibration and verification in model simulations of barotropic and baroclinic flows. The turbulent diffusivities were ascertained through comparison of simulated salinity time series with observations. The model simulation results are in qualitative agreement with the available field data. The validated model was then used to investigate the influence of freshwater discharge on residual current and salinity intrusion under different freshwater inflow condition in the Danshuei River estuarine system. The model results reveal that the characteristic two-layered estuarine circulation prevails most of the time at Kuan-Du station near the river mouth. Comparing the estuarine circulation under low- and mean flow conditions, the circulation strengthens during low-flow period and its strength decreases at moderate river discharge. The river discharge is a dominating factor affecting the salinity intrusion in the estuarine system. A correlation between the distance of salt intrusion and freshwater discharge has been established allowing prediction of salt intrusion for different inflow conditions. ?? 2007 Elsevier Ltd.

    To determine the influence of superstition about Taian (a lucky day)-Butsumetsu (an unlucky day) on decision to leave hospital. To estimate the costs of the effect of this superstition. Retrospective and descriptive study. University hospital in Kyoto, Japan. Patients who were discharged alive from Kyoto University Hospital from 1 April 1992 to 31 March 1995. Mean number, age, and hospital stay of patients discharged on each day of six day cycle. The mean number, age, and hospital stay of discharged patients were highest on Taian and lowest on Butsumetsu (25.8 v 19.3 patients/day, P=0.0001; 43.9 v 41.4 years, P=0.0001; and 43.1 v 33.3 days, P=0.0001 respectively). The effect of this difference on the hospital's costs was estimated to be 7.4 million yen (¿31 000). The superstition influenced the decision to leave hospital, contributing to higher medical care costs in Japan. Although hospital stays need to be kept as short as possible to minimise costs, doctors should not ignore the possible psychological effects on patients' health caused by dismissing the superstition.

    As overweight and obesity is a risk factor for chronic diseases, the development of environmental and healthy public policy interventions across multiple sectors has been identified as a key strategy to address this issue. In 2009, a survey was developed to assess the attitudes and beliefs regarding health promotion principles, and the priority and acceptability of policy actions to prevent obesity and chronic diseases, among key policy influencers in Alberta and Manitoba, Canada. Surveys were mailed to 1,765 key influencers from five settings: provincial government, municipal government, school boards, print media companies, and workplaces with greater than 500 employees. A total of 236 surveys were completed with a response rate of 15.0%. Findings indicate nearly unanimous influencer support for individual-focused policy approaches and high support for some environmental policies. Restrictive environmental and economic policies received weakest support. Obesity was comparable to smoking with respect to perceptions as a societal responsibility versus a personal responsibility, boding well for the potential of environmental policy interventions for obesity prevention. This level of influencer support provides a platform for more evidence to be brokered to policy influencers about the effectiveness of environmental policy approaches to obesity prevention. © 2014 The Obesity Society.

    Full Text Available Effect of pulses of electrical discharge in the water at the magnitude of the limited endurance under cyclic loading thermally hardened carbon steel was investigated. Observed increase stamina during cyclic loading a corresponding increase in the number of accumulated dislocations on the fracture surface. Using the equation of Cofino-Manson has revealed a decrease of strain loading cycle after treatment discharges. For field-cycle fatigue as a result of processing the voltage pulses carbon steel structure improvement, followed by growth of limited endurance decrease per cycle of deformation. With increasing amplitude of the voltage loop gain stamina effect on metal processing voltage pulses is reduced. The results can be used to extend the life of parts that are subject to cyclic loading.

    The comparative analysis of plasma parameters of transverse arc and discharge in the gas channel with liquid wall was made for different working gas and liquids (for air, distilled water and for its mixtures with ethanol). Electronic excitation temperatures Te of atoms, vibrational Tv and rotational Tr temperatures of molecules in the generated plasma were determined by optical emission spectroscopy. It was shown that both discharges generate nonequilibrium plasma in the case of working gas air and working liquid-distilled water. Adding a fuel (ethanol) into the plasma system with O 2 leads to the increasing of rotational and vibrational temperatures of molecules, which became equal to each other within the errors. This may indicate that the exothermic reactions reduce the level of nonthermality of the generated plasma as a result of additional energy supply for heavy components in the process of complete combustion of hydrocarbons.

    2018-02-01

    It is crucial to know the extent to which influences lead to policy capture-by which the policy-making process is shifted away from the public interest towards narrow private interests. Using the case study of Spain, our aim was to identify interactions between public administration, civil society and private companies that could influence health policies. 54 semistructured interviews with key actors related to health policy. The interviews were used to gather information on main policy actors as well as on direct and subtle influences that could modify health policies. The analysis identified and described, from the interviewed persons' experiences, both the inappropriate influences exerted on the actors and those that they exerted. Inappropriate influences were identified at all levels of administration and policy. They included actions for personal benefits, pressure for blocking health policies and pressure from high levels of government in favour of private corporations. The private sector played a significant role in these strategies through bribery, personal gifts, revolving doors, negative campaigns and by blocking unfavourable political positions or determining the knowledge agenda. The interviewees reported subtle forms of influence (social events, offers of technical support, invitations, etc) that contributed to the intellectual and cultural capture of health officials. The health policy decision-making processes in Spain are subject to influences by stakeholders that determine a degree of policy capture, which is avoidable. The private sector uses different strategies, from subtle influences to outright corruption, taking advantage in many cases of flexible legislation. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    The role of river discharge, wind and tide on the extension and variability of the Tagus River plume was analyzed from 2003 to 2015. This study was performed combining daily images obtained from the Moderate Resolution Imaging Spectroradiometer (MODIS) sensor located onboard the Aqua and Terra satellites. Composites were generated by averaging pixels with the same forcing conditions. River discharge shows a strong relation with the extension of the Tagus plume. The plume grows with the increasing river discharge and express a two day lag caused by the long residence time of water within the estuary. The Tagus turbid plume was found to be smaller under northerly and easterly winds, than under southerly and westerly winds. It is suggested that upwelling favoring winds provoke the offshore movement of the plume material with a rapidly decrease in turbidity values whereas downwelling favoring winds retain plume material in the north coast close to the Tagus mouth. Eastern cross-shore (oceanward) winds spread the plume seaward and to the north following the coast geometry, whereas western cross-shore (landward) winds keep the plume material in both alongshore directions occupying a large part of the area enclosed by the bay. Low tides produce larger and more turbid plumes than high tides. In terms of fortnightly periodicity, the maximum plume extension corresponding to the highest turbidity is observed during and after spring tides. Minimum plume extension associated with the lowest turbidity occurs during and after neap tides.

    In this paper we study different effects of excited molecules on swarm parameters, electron energy distribution functions and gas discharge modeling. First we discuss a possible experiment in parahydrogen to resolve the discrepancy in hydrogen vibrational excitation cross section data. Negative differential conductivity (NDC) is a kinetic phenomenon which manifests itself in a particular dependence of the drift velocity on E=N and it is affected by superelastic collisions with excited states. A complete kinetic scheme for argon required to model excited state densities in gas discharges is also described. These results are used to explain experiments in capacitively and inductively coupled RF plasmas used for processing. The paper illustrates the application of atomic and molecular collision data, swarm data and the theoretical techniques in modeling of gas discharges with large abundances of excited molecules. It is pointed out that swarm experiments with excited molecules are lacking and that there is a shortage of reliable data, while the numerical procedures are sufficiently developed to include all the important effects.

  1. Hybrid Simulation of Duty Cycle Influences on Pulse Modulated RF SiH4/Ar Discharge

    2016-04-01

    A one-dimensional fluid/Monte-Carlo (MC) hybrid model is developed to describe capacitively coupled SiH4/Ar discharge, in which the lower electrode is applied by a RF source and pulse modulated by a square-wave, to investigate the modulation effects of the pulse duty cycle on the discharge mechanism. An electron Monte Carlo simulation is used to calculate the electron energy distribution as a function of position and time phase. Rate coefficients in chemical reactions can then be obtained and transferred to the fluid model for the calculation of electron temperature and densities of different species, such as electrons, ions, and radicals. The simulation results show that, the electron energy distribution f(ɛ) is modulated evidently within a pulse cycle, with its tail extending to higher energies during the power-on period, while shrinking back promptly in the afterglow period. Thus, the rate coefficients could be controlled during the discharge, resulting in modulation of the species composition on the substrate compared with continuous excitation. Meanwhile, more negative ions, like SiH-3 and SiH-2, may escape to the electrodes owing to the collapse of ambipolar electric fields, which is beneficial to films deposition. Pulse modulation is thus expected to provide additional methods to customize the plasma densities and components. supported by National Natural Science Foundation of China (No. 11275038)

    2015-01-01

    Responding to a global trend of installing smart meters Norway has taken a route of full governmental and regulatory coordination. The article maps and analyses the main influences on the developments of Norwegian Advanced Metering policy. Based on 12 interviews and extensive document mapping the Norwegian policy developments are traced from about 1990 to 2014, divided into three phases: Before 2000, between 2000 and 2007, and after 2007. It finds that the main influence and push came from an increasingly united industry sector, fronted by the grid utilities with respective interest organizations. Policy change has been boosted by years of constrained supply, creating incentives for political action. Also developments at the EU level have been important for creating attention for smart meters, while consumer groups have been less influential. The national regulator NVE has adapted its policy process to include external expertise, in particular from the grid companies. The findings confirm that influence into policy processes is a matter of financial and organizational resources and expert knowledge. Of particular policy relevance is the weak organization of private consumer interests into these policy streams, which may be important for further policy development for distributed generation and regulation of private generation activities. -- Highlights: •Roll-out of smart meters is in Norway coordinated by national regulation. •Grid companies and related interest organizations has been most influential. •EU has provided informal pressure on smart meter policy. •Consumer interests have been less influential in the policy process

    Full Text Available OBJECTIVE: We aim to compare selective spinal anesthesia and general anesthesia with regard to postoperative recovery and fast-track eligibility in day surgeries. MATERIALS AND METHOD: Sixty geriatric outpatient cases, with ASA II-III physical status and requiring shortduration transurethral intervention, were enrolled in the study. The cases were split into 2 groups: as general anesthesia (Group GA and selective spinal anesthesia (Group SSA. Group GA (n = 30 received propofol 2 mg kg-1 (until loss of eyelash reflex, remifentanil induction 0.5-1 µg kg-1, and laryngeal mask. Maintenance was achieved by 4-6% desflurane in 60% N2O and 40% O2 along with remifentanil infusion at 0.05 µg /kg-1 /min-1. Drugs were discontinued after the withdrawal of the ureteroscope, and extubation was carried out with 100% O2. Group SSA (n = 30 received 0.5% spinal anesthesia via L4-5 space by 0.5% hyperbaric bupivacaine 5 mg. Anesthesia preparation time, time to surgical anesthesia level, postoperative fast-tracking, and time to White-Song recovery score of 12, were noted. In the operating room, we evaluated hemodynamics, nausea/vomiting, surgeon and patient satisfaction with anesthesia, perioperative midazolam-fentanyl administration, postoperative pain, and discharge time. RESULTS: Anesthesia preparation time, length of surgery, anesthesia-related time in the operating room, time to sit, and time to walk were significantly low in Group GA (p < 0.05, whereas time to fast-track eligibility, length of stay in the PACU, discharge time, and other parameters were similar in both of the groups. CONCLUSION: While anesthesia preparation time, length of surgery, start time of surgery, time to sit, and time to walk were shorter in the General Anesthesia group, time to fast-track eligibility, phase 1 recovery time, and discharge time were similar among patients subjected to selective spinal anesthesia.

The calculations have been carried out for various values of the cathode heights hк (from 0.02 to 0.05 m. Diameter of a target cathode is equal to 0.08 m for a majority of technological plasma devices, therefore, the area of the erosion surface is S = 0.005 m2.A thickness selection for a consumable target cathode part in the vacuum arc plasma source has been justified in the paper. The thickness ensures formation of minimum drop phase in the plasma flow during arc cathode material evaporation. It has been shown that a maximum admissible current of an arc discharge is practically equal to the minimum current of stable arcing when thickness of the consumable cathode part is equal to 0.05 m. The admissible discharge current can be rather significant and ensure high productivity during coating process with formation of relatively low amount of droplet phase in the coating at small values of hк.

    In the last two years, the new MR6 type fuel containing 1550 g of U with 36% enrichment has been loaded into MARIA reactor core. Its aluminium cladding thickness is 0,6 mm and typical burnup -about 4080 MWh (as compared to 2880 MWh for the 80% enriched fuel used). However, increased fission product release from these assemblies was observed near the end of its operational time. The results presented earlier [1] show that the corrosion behaviour of aluminium cladding depends on the conditions of fuel operation in the reactor. The corrosion process in the aluminum of fuel cladding proceeds faster then in the aluminum of constructional elements. This tendency was also observed in MR-6/80% and in WWR- SM fuel assemblies. Therefore the visual tests of discharged MR-6/36% fuel elements were performed. Some change of appearance of aluminum cladding was observed, especially in the regions with large energy generation i.e. in the centre of reactor core and in the strong horizontal gradient of neutron flux. In the present paper, the results of visual investigation of discharged fuel assemblies are presented. The results of the investigation are correlated with the operational parameters. (author)

    Partial discharges (PDs) due to artificial void in samples of LDPE nanocomposite sheet have been investiga- ted in this work. PDs may cause the degradation of insulating materials and may affect the lifetime of high-voltage ap- paratus. An experimental work using sphere ball-plane electrode system (CIGRE Method II) and a 1.0 mm LDPE composite sheet was carried out. Different weight percentages of nanosilica (0%, 2%, 4%, 6% and 8%) were used. PD experimental results, such as PD magnitude and PD number (both PD pulse polarities), as functions of the ap- plied stress duration at a specified applied voltage were compared. The surface morphology of specimens was also presented and this conforms to the PD findings. The experimental results show that the PD characteristics of the LDPE generally improve with the introduction of nanosilica, the composite with the highest content of filler, namely the 8% (wt) nanosilica sample has the least partial discharge activities.

  14. Structural properties of nitrogenated amorphous carbon films: Influence of deposition temperature and radiofrequency discharge power

    The structural properties of nitrogenated amorphous carbon deposited by radiofrequency magnetron sputtering of graphite in pure N 2 plasma are investigated as a function of the substrate temperature and radiofrequency discharge power. The film composition is derived from x-ray photoemission spectroscopy, nuclear reaction analysis and elastic recoil detection measurements and the film microstructure is discussed using infrared, Raman, x-ray photoemission and near edge x-ray absorption fine structure spectroscopic results. At low deposition temperature and low radiofrequency power, the films are soft, porous, and easily contaminated with water vapor and other atmospheric components. The concentration of nitrogen in the films is very large for low deposition temperatures (∼33.6 at. % N at 150 deg. C) but decreases strongly when the synthesis temperature increases (∼15 at. % N at 450 deg. C). With increasing deposition temperature and discharge power values, the main observed effects in amorphous carbon nitride alloys are a loss of nitrogen atoms, a smaller hydrogen and oxygen contamination related to the film densification, an increased order of the aromatic sp 2 phase, and a strong change in the nitrogen distribution within the carbon matrix. Structural changes are well correlated with modifications of the optical and transport properties

  1. A literature review of organisational, individual and teamwork factors contributing to the ICU discharge process.

    Lin, Frances; Chaboyer, Wendy; Wallis, Marianne

    2009-02-01

    It is everyday news that we need more intensive care unit (ICU) beds, thus effective use of existing resources is imperative. The aim of this literature review was to critically analyse current literature on how organizational factors, individual factors and teamwork factors influence the ICU discharge process. A better understanding of discharge practices has the potential to ultimately influence ICU resource availability. Databases including CINAHL, MEDLINE, PROQUEST, SCIENCE DIRECT were searched using key terms such as ICU discharge, discharge process, ICU guidelines and policies, discharge decision-making, ICU organisational factors, ICU and human factors, and ICU patient transfer. Articles' reference lists were also used to locate relevant literature. A total of 21 articles were included in the review. Only a small number of ICUs used written patient discharge guidelines. Consensus, rather than empirical evidence, dictates the importance of guidelines and policies. Premature discharge, discharge after hours and discharge by triage still exist due to resources constraints, even though the literature suggests these are associated with increased mortality. Teamwork and team training appear to be effective in improving efficiency and communication between professions or between clinical areas. However, this aspect has rarely been researched in relation to ICU patient discharge. Intensive care patient discharge is influenced by organisational factors, individual factors and teamwork factors. Organisational interventions are effective in reducing ICU discharge delay and shortening patient hospital stay. More rigorous research is needed to discover how these factors influence the ICU discharge process.

    Ethylene gas is decomposed using a dielectric barrier discharge plasma reactor for long-period preservation of fruits and vegetables. The oxygen concentration in ambient gas is varied from 2 to 20% to simulate the fruit and vegetable transport container. The experimental results show that the efficiency of ethylene gas decomposition increases with decreasing oxygen concentration. The reactions of ethylene molecules with ozone are analyzed by Fourier transform infrared spectrometry. The analysis results show that the oxidization process by ozone is later than that by oxygen atoms. The amount of oxygen atoms that contribute to ethylene removal increases with decreasing oxygen concentration because the reaction between oxygen radicals and oxygen molecules is suppressed at low oxygen concentrations. Ozone is completely removed and the energy efficiency of C2H4 removal is increased using manganese dioxide as a catalyst.

  3. Magnetic field structure influence on primary electron cusp losses for micro-scale discharges

    2014-01-01

    An experimental effort was used to examine the primary electron loss behavior for micro-scale (≲3 cm diameter) discharges. The experiment uses an electron flood gun source and an axially aligned arrangement of ring-cusps to guide the electrons to a downstream point cusp. Measurements of the electron current collected at the point cusp show an unexpectedly complex loss pattern with azimuthally periodic structures. Additionally, in contrast to conventional theory for cusp losses, the overall radii of the measured collection areas are over an order of magnitude larger than the electron gyroradius. Comparing these results to Monte Carlo particle tracking simulations and a simplified analytical analysis shows that azimuthal asymmetries of the magnetic field far upstream of the collection surface can substantially affect the electron loss structure and overall loss area

    Highlights: ► Reliable quench detection in EAST is a key issue for steady-state operation. ► The electromagnet noise interference associated with detection signals under different discharge conditions are evaluated. ► The effective measures have been realized on detection systems. ► Recently upgrade work has been done, especially for the optimization of ACS and false FSDS were reduced greatly. -- Abstract: EAST is the first Tokamak device whose toroidal and poloidal magnet are superconducting. The enormous magnetic field energy stored in the magnet system will transfer into thermal energy and cause the damage of superconducting magnet, if a quench happened. Therefore, reliable quench detection is a key issue for steady-state operation. In addition to electromagnetic noise from poloidal magnet fields and plasma current which will experience fast current ramp rate, radio frequency noise from heating system also have some interference on quench detection system to a certain degree. The most difficult point for quench detection system is required to have more detail evaluation on electromagnetic noise interference. Recently experiments have been carried out successfully in EAST device. The steady-state operation with 1 MA of plasma current and more than 100-s plasma duration has been obtained. In the paper, the electromagnetic noise interference on quench detection system under different discharge conditions are analyzed and relative process methods are also introduced. The technological experience and experimental data are significant for the constructing ITER and similar superconducting device have been mentioned which will supply significant technological experience and experimental data for constructing ITER and similar superconducting device

    Highlights: • PD detection method was used to check the quality of the superconducting busbar insulation. • The samples with different void fraction were manufactured for comparing. • The discharge inception voltage, PRPD pattern was tested and studied for the samples with different void content. • The PD behaviors in oil bath and air condition were compared. - Abstract: For a magnetic confinement fusion device, the superconducting magnets and busbars need to be insulated with one layer of solid insulation to isolate the high voltage potential from the ground. The insulation layer commonly consists of several interleaved layers of epoxy resin-impregnated glass fiber tapes and polyimide films. The traditional electrical inspection methods for such solidified insulation on the magnet and busbar are a DC voltage test or a Paschen test. These tests measure the quality of the insulation based on the value of leakage currents. However, even if there is a larger quantity of high dielectric strength material implemented, if there are some microcavities or delaminations in the insulation system, the leakage current may be limited to microampere levels under testing levels over dozens of kilovolts. Therefore, it is difficult to judge the insulation quality just by the magnitudes of leakage current. Under long-term operation, such imperceptible defects will worsen and finally completely break down the insulation because of partial discharge (PD) incidents. Therefore, a PD detection test is an important complement to the DC voltage and Paschen tests for magnet and busbar insulations in the field of fusion. It is known that the PD detection test is a mature technique in the electric power industry. In this paper, the PD characteristics of samples containing glass fiber-reinforced composite insulations for use with the superconducting busbar were presented and discussed. Various samples with different void contents were prepared and the PD behaviors were tested.

    2009-03-01

    SummaryThe environmental and anthropogenic factors controlling sediment delivery to the sea are numerous, intricate and usually difficult to quantify. Mediterranean watersheds are historically amongst the most heavily impacted by human activities in the world. This study analyzes some of these factors for nine river systems from Catalonia, NE Spain, that open into the Northwestern Mediterranean Sea, and discusses the results obtained from sediment yield models and sediment concentration data series. General models indicate that the natural suspended sediment yield by individual Catalan rivers ranged within a fork from 94 to 621 t km -2 yr -1. Such a sediment yield would be noticeably reduced (moving the fork to 7-148 t km -2 yr -1) because of lithological factors and direct anthropogenic and, possibly, climatic impacts. Damming, water extraction and urbanization appear as the most important direct anthropogenic impacts in Catalonia. Water discharge and sediment concentration measurements by basin authorities provide much lower sediment yield estimations, from 0.4 to 19.8 t km -2 yr -1, which is probably due to the lack of measured sediment loads during flood events, as it is the case in many other Mediterranean rivers. The Catalan watersheds have some of the smallest runoff values amongst Mediterranean rivers. Of the nine river systems studied, water discharge tends to decrease in two and to increase in one. The other six river systems do not show any clear tendency. Related to climatic parameters, temperature raised in all the watersheds between 1961 and 1990, while precipitation did not show significant trends.

  8. Influence of the polarity of the applied voltage on the reignition of a discharge below a dielectric layer in air at atmospheric pressure

    Pechereau, François; Bourdon, Anne

    2014-01-01

    The dynamics of an atmospheric pressure air discharge in a point-to-plane geometry with a dielectric layer obstacle on the discharge path is investigated numerically for different applied voltages. Whatever the polarity of the voltage applied, first, a streamer discharge of the same polarity ignites at the point and propagates towards the dielectric layer. After the impact on the dielectric surface, the streamer discharge spreads along the upper dielectric surface and charges it positively or negatively depending on its polarity. On the bottom surface of the dielectric layer, charges with an opposite polarity are deposited. Surface charges on both faces of the dielectric layer are shown to have a significant influence on the discharge reignition for a negative applied voltage, but not for a positive one. Furthermore, it is shown that the dynamics of the discharge reignition below the dielectric layer depends on the polarity of the applied voltage at the point electrode. For a positive applied voltage, the reignited discharge is a positive ionization wave propagating towards the grounded plane. For a negative applied voltage, a double headed discharge is observed with positive and negative fronts propagating in opposite directions. Finally, the minimal value of the ionization integral to have a discharge reignition below the dielectric obstacle is found to be less for a negative applied voltage than for a positive one. (paper)

    Appetite regulation is influenced by the environment, and the environment is shaped by food-related policies. This review summarizes the environment and policy research portion of an NIH Workshop (Bethesda, MD, 2015) titled "Self-Regulation of Appetite-It's Complicated." In this paper, we begin by making the case for why policy is an important tool in efforts to improve nutrition, and we introduce an ecological framework that illustrates the multiple layers that influence what people eat. We describe the state of the science on how policies influence behavior in several key areas: the federal food programs, schools, child care, food and beverage pricing, marketing to youth, behavioral economics, and changing defaults. Next, we propose novel approaches for multidisciplinary prevention and intervention strategies to promote breastfeeding, and examine interactions between psychology and the environment. Policy and environmental change are the most distal influences on individual-level appetite regulation, yet these strategies can reach many people at once by changing the environment in which food choices are made. We note the need for more research to understand compensatory behavior, reactance, and how to effectively change social norms. To move forward, we need a more sophisticated understanding of how individual psychological and biological factors interact with the environment and policy influences. © 2017 The Obesity Society.

    Populations of benthic and epifaunal macro-organisms living in the area influenced by the thermal discharge of the steam-electric power plant at Humboldt Bay, California, were analyzed in 1971 and 1972 to determine if differences in distribution could be attributed to the effluent. Relicated benthic samples were collected with a Ponar grab at 20 stations in the bay and at 4 stations in the canals leading to and from the power plant. Comparisons of epifaunal plants and animals in a rocky intertidal zone were made at 13 permanent transects spaced at various distances on either side of the discharge. Species richness in the intertidal was positively correlated with increased temperature in 13 percent of the possible combinations of tide level and diversity. Individual species were positively correlated with increased temperatures for 19 percent of the plant comparisons, and for 16.3 percent of the animal comparisons. Comparisons of populations of individual species in the heated intertidal zone with those in a control zone indicated differences in 26.2 percent of the plant surveys, and 23.2 percent of the animal surveys. Differences were positively related to the increased temperature in 90.5 percent of the comparisons. Proportions of eurythermal plants or animals in the heated areas of the intertidal zone did not differ significantly from proportions in other areas in 4 different survey periods. With the possible exception of one species, there was no conclusive evidence that any of the 132 species found in the intertidal area at Humboldt Bay was eliminated from the heated area surrounding the discharge of the power plant

    The predicted increase in world demand for electricity requires that the gift of nuclear energy that has served developed nations must not be wasted. The development of nuclear energy is hampered by the absence of a clear and unequivocal policy regarding the storage and disposal of radioactive waste and is seen by a significant section of the public as a threat to their rights. Public opposition may cause the demise of nuclear electric power in developed nations and proscribe its use in the third world. (author)

    Full Text Available Brazilian national tourism policies have relied on local agency, which had been formerly used in Minas Gerais state through the Tourist Circuits Policy. Being that new policies cause changes in relations among agents, this paper aims to identify the influence of the Tourist Circuits Policy in agents´ behavior as well as in financial transactions. Research assessed that Tourist Circuits Policy created a government structure that favored easier and more frequent relations among agents, reduced uncertainty, opportunism and the possibility of investments to be lost. As a result, researchers believe that Tourist Circuits Policy has been a contributor for the lowering of transactions costs, even though some adjustments are still needed.

    2016-01-01

    The effect of various air flow parameters on the plasma regimes of nanosecond repetitively pulsed (NRP) discharges is investigated at atmospheric pressure. The two electrodes are in a pin-annular configuration, transverse to the mean flow. The voltage pulses have amplitudes up to 15 kV, a duration of 10 ns and a repetition frequency ranging from 15 to 30 kHz. The NRP corona to NRP spark (C-S) regime transition and the NRP spark to NRP corona (S-C) regime transition are investigated for different steady and harmonically oscillating flows. First, the strong effect of a transverse flow on the C-S and S-C transitions, as reported in previous studies, is verified. Second, it is shown that the azimuthal flow imparted by a swirler does not affect the regime transition voltages. Finally, the influence of low frequency harmonic oscillations of the air flow, generated by a loudspeaker, is studied. A strong effect of frequency and amplitude of the incoming flow modulation on the NRP plasma regime is observed. Results are interpreted based on the cumulative effect of the NRP discharges and an analysis of the residence times of fluid particles in the inter-electrode region. © 2016 IOP Publishing Ltd.

    This paper reports about experiences gathered from five online monitoring campaigns in the sewer systems of Berlin (Germany), Graz (Austria), Lyon (France) and Bogota (Colombia) using ultraviolet-visible (UV-VIS) spectrometers and turbidimeters. Online probes are useful for the measurement of highly dynamic processes, e.g. combined sewer overflows (CSO), storm events, and river impacts. The influence of local calibration on the quality of online chemical oxygen demand (COD) measurements of wet weather discharges has been assessed. Results underline the need to establish local calibration functions for both UV-VIS spectrometers and turbidimeters. It is suggested that practitioners calibrate locally their probes using at least 15-20 samples. However, these samples should be collected over several events and cover most of the natural variability of the measured concentration. For this reason, the use of automatic peristaltic samplers in parallel to online monitoring is recommended with short representative sampling campaigns during wet weather discharges. Using reliable calibration functions, COD loads of CSO and storm events can be estimated with a relative uncertainty of approximately 20%. If no local calibration is established, concentrations and loads are estimated with a high error rate, questioning the reliability and meaning of the online measurement. Similar results have been obtained for total suspended solids measurements.

  18. Influences of Traction Load Shock on Artificial Partial Discharge Faults within Traction Transformer—Experimental Test for Pattern Recognition

    Directory of Open Access Journals (Sweden)

    Shuaibing Li

    2017-10-01

    Full Text Available Partial discharge (PD measurement and its pattern recognition are vital to fault diagnosis of transformers, especially to those traction substation transformers undergoing repetitive traction load shocks. This paper presents the primary factors induced by traction load shocks including high total harmonics distortion (THD, transient voltage impulse and high-temperature rise, and their effects on the feature parameters of PD. Experimental tests are conducted on six artificial PD models with these factors introduced one by one. Results reveal that the maximum PD quantity and the PD repetitive rate are favorable to be enlarged when the oil temperature exceeds 80 °C or the THD is higher than 16% with certain orders of harmonic. The decline in PD inception voltage can mainly be attributed to the transient voltage impulse. The variation in central frequency of the fast Fourier transformation (FFT spectra transformed from ultra-high frequency signals can mainly be attributed to high THD, especially when it exceeds 20%. The temperature rise has no significant influence on the FFT spectra; the transient voltage impulse, however, can result in a central frequency shift of the floating particle discharge. With the rapid development of high-speed railways, the study presented in this paper will be helpful for field PD detection and recognition of traction substation transformers in the future.

  19. THE INFLUENCE OF ACCOUNTING POLICIES OVER THE ENTITIES’ RESULT

    Full Text Available This article started from the idea that International Accounting and Financial Reporting Standards have had a major impact over the accounting world. Accounting laws of Continental Europe (especially France centered on historical cost, are in opposition to IFRS towards fair value. If accounting is based on historical cost we can say that excess of prudence leads to inaction. On the other hand the Anglo-Saxon accounting system is based on fair value that looks for a quick profit and to help investors. Financial statements record how resources have been handled by the management. The role of financial statements is to provide informations that will help users to make decisions. They can accomplish this mission only for those objectives that can be quantified as value and quantity. IFRS is referring to the whole set of financial statements that have to include a statement of the financial position, of the result, of changes in equity and treasury. Alongside these informations has to be a summary of significant accounting policies as well as informations about retrospective application of one or more accounting policies.

    Full Text Available Development Policies in Alba Iulia Area of Influence. An Integrated Approach. The paper represents an integrated and holarchical perspective on the spatial development policies and its component measures and projects related to the City of Alba Iulia, its area of influence and the all-encompassing County of Alba, Romania. The goal was to see how the development and management policies from all levels merge into a single strategic framework that might create a favourable basis for the sustainable growth of Alba Iulia and its area of influence. As this area surrounding the city is subjected to different hierarchical plans and programmes, some that are not properly correlated, it is extremely clear that this area and Areas of Influence in general need legislative stipulations made specifically for them and also a well-thought holarchical planning approach.

    In-Home nursing care of the preterm newborn helps to bring the family situation to normal, promotes breastfeeding and development of the newborn, and enables the reorganization of health care resources. The purpose of this paper is to demonstrate that in-home nursing care of the preterm newborn leads to an increase in weight and a similar morbidity. A total of 65 cases and 65 controls (matched by weight, age and sex) were studied, all of them preterm newborns born in hospital and weighing less than 2100 g at discharge. In-home nursing care was carried out by a pediatrician neonatologist, as well as two nurses specialized in neonatology who made several visits to the home. Weight gain was calculated as g/day and g/Kg/day, comparing the first week of the study with the week prior to the beginning of the study. The groups were comparable. Weight gain in the group with home nursing care was 38 g per day, significantly higher than the weight gain in the control group (31 g/day). The independent predictive variables of the increase in g/Kg/day during the study were in-home nursing care, male gender, breastfeeding less, and not having suffered from a peri-intraventricular hemorrhage. Neonatal morbidity was similar in both groups. In-home care was associated with a greater weight gain of the newborn at home than during their stay in the hospital, and can be considered safe because neonatal morbidity was not increased.

    In this contribution an effect of dielectric barrier discharge (DBD) sustained in air at atmospheric pressure on surface properties of poly(ethylene terephthalate) (PET) foils is studied. It is found that exposure of PET to DBD plasma leads to rapid changes of surface chemical composition, wettability, surface morphology as well as mechanical properties of PET surface. In addition, based on biological tests that were performed using two cell types (Saos-2 human osteoblast-like cells and HUVEC human umbilical vein endothelial cells), it may be concluded that DBD plasma treatment positively influences cell growth on PET. This effect was found to be connected predominantly with increased surface energy and oxygen content of the surface of treated PET foils.

    2016-07-01

    The influence of sodium carbonate on the decomposition of formic acid by discharge inside bubbles in water was investigated experimentally. Oxygen or argon gases were injected into the water through a vertically positioned glass tube, in which the high-voltage wire electrode was placed to generate plasmas at low applied voltage. The concentration of formic acid was determined by ion chromatography. In the case of sodium carbonate additive, the pH increased owing to the decomposition of the formic acid. In the case of oxygen injection, the percentage of conversion of formic acid increased with increasing pH because the reaction rate of ozone with formic acid increased with increasing pH. In the case of argon injection, the percentage of conversion was not affected by the pH owing to the high rate loss of hydroxyl radicals.

    Full Text Available The present work reports an investigation of the influence of the radial spacing between cathodes on the iron sintering process by hollow cathode electrical discharge, with surface enrichment of the alloying elements Cr and Ni. Pressed cylindrical samples of 9.5 mm diameter and density of 7.0 ± 0.1 g/cm³ were prepared by compaction of Ancorsteel 1000C iron powder. These samples, constituting the central cathode, were positioned concentrically in the interior of an external cathode machined from a tube of stainless steel AISI 310 (containing: 25% Cr, 16% Ni, 1.5% Mn, 1.5% Si, 0.03% C and the remainder Fe. Sintering was done at 1150 °C, for 120 min, utilizing radial spacings between the central and hollow cathodes of 3, 6 and 9 mm and a gas mixture of 80% Ar and 20% H2, with a flow rate of 5 cm³/s at a pressure of 3 Torr. The electric discharge was generated using a pulsed voltage power source, with a period of 200 mus. The radial spacing had only a slight influence on the quantity of atoms of alloying elements deposited and diffused on the surface of the sample. Analysis with a microprobe showed the presence of chrome (up to 4.0% and nickel (up to 3.0%, in at. % at the surface of the samples. This surface enrichment can be attributed to the mechanism of sputtering of the metallic atoms present in the external cathode, with the deposition of these elements on the sample surface and consequent diffusion within the sample.

  7. Media and politics: Empirical data on their cross-influence in health policy.

    Science.gov (United States)

    2011-01-01

    OBJECTIVES: Despite the central influence of public policies on health and welfare, relatively little is known about actual health care policy-making processes. This presentation will offer preliminary results from a federally funded project aimed at gaining insights into the interrelations among interest-group strategies, media discourses and political debates in health care. The policy debate on health care privatization in Quebec is used as a case study. APPROACH: Two sources of data were used: media sources and political debates. Media sources were the six main provincial newspapers in Quebec, two national newspapers and The Canadian Press, as well as transcripts from specific news-related programs of three national television stations and two national radio stations. Political debates were obtained through transcripts of all question periods in the Parliament and debates in the standing committee on health. Sources were systematically searched to identify all relevant data. Multiple search syntaxes were developed and tested to maximize sensitivity and specificity. All data was entered and coded into qualitative analysis software. RESULTS: Data was analyzed longitudinally from June 2005 to January 1, 2010. Four levels of results will be presented: 1) Descriptive analysis of the interest groups involved, their policy preferences and the rhetoric they employed to support their views. 2) Descriptive analysis of the main policy proposals that structured the debate as well as of the coalition of groups behind those proposals. 3) Graphic longitudinal analysis of the intensity of the debate and of the relative importance and evolution of various policy proposals. 4) Preliminary results on the nature, direction and level of inter-influence between the policy and media agendas. CONCLUSION: This presentation provides empirical evidence on current policy-making processes in health care. It shows, unsurprisingly, that policy-making is a circumvoluted process of inter-influence

  8. Impact of oil on the marine environment: policy of the Paris Commission on operational discharges from the offshore industry

    1994-01-01

    The input of oil to the North Sea due to the offshore industry has been estimated at 29% of the total input of oil. The operational discharges consist of production water and drilling cuttings. An overview of statistics collected over the last 10 years shows that although the amount of oil discharged via production water is increasing as platforms are getting older, cuttings still account for 75% of the oil entering the sea as a result of normal operations. Spills represent a relatively small source of oil. The effects on the marine environment of discharges of production water and of discarded oily cuttings have been extensively studied, by national authorities as well as by the industry. Although it has not always been possible to reach consensus about the significance of the observed effects, a number of 'agreed facts' have led to the establishment of regulations in the framework of the Paris Commission. The 'decisions' and 'recommendations' adopted by the Commission are regularly reviewed in the light of new developments. (author)

    Hawkins, Benjamin; Holden, Chris; McCambridge, Jim

    2012-09-01

    The British government has been criticised for according industry interests too much weight in alcohol policy-making. Consequently, it has been argued that alcohol strategy in the UK is built around policies for which the evidence base is weak. This has clear implications for public health. The purpose of this commentary is to map recent developments in UK alcohol policy and related debates within the alcohol policy literature, thus laying the foundations for a systematic examination of the influence of the alcohol industry on alcohol policy. It highlights the changing structure of the industry and summarises what is known about the positions and strategies of industry actors towards alcohol policy. In so doing, it aims to contribute not just to debates about alcohol policy, but to a broader understanding of health policy processes and the relationships between government and other stakeholders. It advances a new research agenda focused on the role of corporate actors in the field of alcohol policy and public health more broadly.

  11. Influence of Government economic policies on mining legislation

    1980-01-01

    As we know from experience, the relation between state and economy is characterized by more or less strong tensions. The following three groups have always claimed the right to dispose of mineral resources: the state - in former times the sovereign -, the landowners, and the mining industry. The first one has based his claim on his official power and has taken the view that he alone could protect the interests of the general public in winning mineral resources. The second ones have relied on their titles to real estates which basically cover unlimited depth. With the intent to work the mines, the mining industry refers to its know-how, performance and readiness, thus alleging that they would serve the national economy best. The historical development of mining laws has finally been characterized by a shift in priorities within these naturally strained relations which exist between state, landowners, and mining industry. It is examined how the emphasis has been shifted in this relationship in the course of time, with special consideration of the relationship between state and mining industry. Which rules of law the legislator intends to make with regard to mining laws will always depend on the question as to which economic policy the state intends to pursue.

    Rivers are among some of the most complex and important ecosystems in the world. Unfortunately, many fishes endemic to rivers have suffered declines in abundance and distribution suggesting that alterations to lotic environments have negatively influenced native fish populations. Of the 35 fishes native to the Colorado River basin (CRB), seven are considered either endangered, threatened, or species of special concern. As such, the conservation of fishes native to the CRB is a primary interest for natural resource management agencies. One of the major factors limiting the conservation and management of fishes endemic to the CRB is the lack of basic information on their ecology and population characteristics. We sought to describe the population dynamics and demographics of three populations of Bluehead Suckers (Catostomus discobolus) and Flannelmouth Suckers (C. latipinnis) in Utah. Additionally, we evaluated the potential influence of altered flow regimes on the recruitment and growth of Bluehead Suckers and Flannelmouth Suckers. Mortality of Bluehead Suckers and Flannelmouth Suckers from the Green, Strawberry, and White rivers was comparable to other populations. Growth of Bluehead Suckers and Flannelmouth Suckers was higher in the Green, Strawberry, and White rivers when compared to other populations in the CRB. Similarly, recruitment indices suggested that Bluehead Suckers and Flannelmouth Suckers in the Green, Strawberry, and White rivers had more stable recruitment than other populations in the CRB. Models relating growth and recruitment to hydrological indices provided little explanatory power. Notwithstanding, our results indicate that Bluehead Suckers and Flannelmouth Suckers in the Green, Strawberry, and White rivers represent fairly stable populations and provide baseline information that will be valuable for the effective management and conservation of the species.

    Full Text Available The objective was to identify the main factors influencing micronutrient policies in the opinion of policy actors in ten European countries. Study was carried out during Jan-Nov 2010 in European countries: the Czech Republic, Denmark, England, Germany, Greece, Italy, the Netherlands, Norway, Poland and Spain. Semi-structured qualitative interviews were conducted with representatives of stakeholders involved in the vitamin D, folate and iodine policy making process. Fifty eight key informants representing mainly scientific advisory bodies (n=24 and governmental organisations (n=19 participated in the study. The remaining interviewees represented non-governmental organisations (n=6, industry (n=4 or were independent academic or health professional experts (n=5. Data were analysed by theoretical interpretative thematic analysis. Insights from interviewees on the development of micronutrient policies were grouped using the Public Health Nutrition Policy-making model. The main factors influencing the micronutrient policies were: systematic monitoring of nutrition and health, causal relationships between consumers’ diet-related behaviours and health outcomes, scientific recommendations from national bodies (Science area; scientific recommendations from international authorities and experiences of other countries, EU legislation, cultural factors (Wider context and political environment, national capacity to deal with the problem, national legislation, economics, stakeholder engagement, relationships between stakeholders (Policy and institutions area. The spectrum and weight of the factors influencing nutritional policy depends on nutrient, country and degree of its “advanced status” within nutrition policy, political environment, culture and socio-economic conditions as well as the point of view (who is expressing the opinion.

  16. Influence of non-technical policies on choices of waste solidification technologies

    International Nuclear Information System (INIS)

    Trubatch, S.L.

    1987-01-01

    This paper describes and discusses non-technical policy considerations which may improperly influence decisions on the solidification of low-level radioactive wastes (''LLW''). These policy considerations are contained principally in several State and Federal statutes which regulate various aspects of LLW disposal. One policy consideration in particular, the unqualified bias in favor of volume reduction, is shown to present a substantial potential for leading to technically suboptimal decisions on the appropriate processes for solidifying LLW. To avoid the unintended skewing of technical decisions by non-technical policy considerations, certain current policies may need to be revised to ensure that the choices of waste treatment, including decisions on solidification, are based primarily on reasonable assurance of adequate protection of public health and safety. This goal may be realized in part by basing any disposal fee structure on more than just LLW volume to include consideration of the waste's activity and its difficulty of confinement

    1990-01-01

    Current practice of North Sea States on the discharge and disposal of liquid radioactive wastes to the North Sea are based on the declaration issued at the Second International Conference on the Protection of the North Sea, known as the London Declaration. This has three main points the first of which emphasises the application of the Best Available Technology to protect the North Sea, the second provides a framework on which future controls on radioactive discharges should be based. The third identifies two parts of the framework; to take into account the recommendations of international organizations and that any repositories of radioactive waste which are built should not pollute the North Sea. This chapter looks at how the concensus based on the London Declaration is working, gauges the progress made in the implementation of the policy goal, identifies existing and future areas for concern and proposes ways of strengthening the control of radioactive discharges. The emphasis is on the United Kingdom practice and regulations for liquid wastes, most of which comes from the Sellafield Reprocessing Plant. (author)

  18. The Influence of Swirl Brakes and a Tip Discharge Orifice on the Rotordynamic Forces Generated by Discharge-to-Suction Leakage Flows in Shrouded Centrifugal Pumps

    1993-01-01

    Recent experiments conducted in the Rotor Force Test Facility at the California Institute of Technology have examined the effects of a tip leakage restriction and swirl brakes on the rotordynamic forces due to leakage flows on an impeller undergoing a prescribed circular whirl. The experiments simulate the leakage flow conditions and geometry of the Alternate Turbopump Design (ATD) of the Space Shuttle High Pressure Oxygen Turbopump and are critical to evaluating the pump's rotordynamic instability problems. Previous experimental and analytical results have shown that discharge-to-suction leakage flows in the annulus of a shrouded centrifugal pump contribute substantially to the fluid induced rotordynamic forces. Also, previous experiments have shown that leakage inlet (pump discharge) swirl can increase the cross-coupled stiffness coefficient and hence increase the range of positive whirl for which the tangential force is destabilizing. In recent experimental work, the present authors demonstrated that when the swirl velocity within the leakage path is reduced by the introduction of ribs or swirl brakes, then a substantial decrease in both the destabilizing normal and tangential forces could be achieved. Motivation for the present research is that previous experiments have shown that restrictions such as wear rings or orifices at pump inlets affect the leakage forces. Recent pump designs such as the Space Shuttle Alternate Turbopump Design (ATD) utilize tip orifices at discharge for the purpose of establishing axial thrust balance. The ATD has experienced rotordynamic instability problems and one may surmise that these tip discharge orifices may also have an important effect on the normal and tangential forces in the plane of impeller rotation. The present study determines if such tip leakage restrictions contribute to undesirable rotordynamic forces. Additional motivation for the present study is that the widening of the leakage path annular clearance and the

    This article develops and explores a methodology for using qualitative influence diagrams in environmental policy and management to support decision-making efforts that minimize risk and increase resiliency. Influence diagrams are representations of the conditional aspects of a problem domain. Their graphical properties are useful for structuring causal knowledge relevant to policy interventions and can be used to enhance inference and inclusivity of multiple viewpoints. Qualitative components of influence diagrams are beneficial tools for identifying and examining the interactions among the critical variables in complex policy development and implementation. Policy interventions on social-environmental systems can be intuitively diagrammed for representing knowledge of critical relationships among economic, environmental, and social attributes. Examples relevant to coastal resiliency issues in the US Gulf Coast region are developed to illustrate model structures for developing qualitative influence diagrams useful for clarifying important policy intervention issues and enhancing transparency in decision making.

    An understanding of the characteristics of pollutants on impervious surfaces is essential to estimate pollution loads and to design methods to minimize the impacts of pollutants on the environment. In this study, simulated rainfall equipment was constructed to investigate the pollutant discharge process and the influence factors of urban surface runoff (USR). The results indicated that concentrations of total suspended solids (TSS), total nitrogen (TN), total phosphorus (TP) and chemical oxygen demand (COD) appeared to be higher in the early period and then decreased gradually with rainfall duration until finally stabilized. The capacity and particle size of surface dust, rainfall intensity and urban surface slopes affected runoff pollution loads to a variable extent. The loads of TP, TN and COD showed a positive relationship with the surface dust capacity, whereas the maximum TSS load appeared when the surface dust was 0.0317 g·cm⁻². Smaller particle sizes (pollution carrying capacity of runoff, leading to higher pollution loads. Knowledge of the influence factors could assist in the management of USR pollution loads.

    1978-09-01

    A numerical study of the pressure and temperature profiles of an infinitely long quasi-cylindrical discharge in hydrogen gas is presented. In particular the influence of the diffusion of atoms in the ground state and the reabsorption of Lyman-α and Lyman-β radiation on both the particle balance and the energy balance of the discharge is studied. Because the transport of the charged particles is corrected for toroidal effects in the regime of high collisionality which is present in the discharge, the model is quasi-cylindrical. The results obtained show an increase of the neutral density on the axis and of the ion and electron density near the wall of the discharge, as compared with earlier calculations in which both diffusion and reabsorption of radiation were neglected. The results are in agreement with measurements in the 'Ringboog' experiment. (Auth.)

    Full Text Available The Peruvian Constitution grants presidents the power to participate in the policy making process. At the same time, the Peruvian Congress is considered to lack the technical and professional ability to fully participate in such a process. However, such analysis neglects the influence that the Congress can exert through informal politics. Based on 31 interviews with legislators, political authorities, officials and experts in public administration this paper shows that the Peruvian legislature participates in the policy making process albeit through informal channels of influence over the bureaucracy.

    2018-02-01

    The introduction of new policies can evoke strong emotional reactions by the public. Yet, social-psychological research has paid little attention to affective determinants of individual-level policy acceptance. Building on recent theoretical and empirical advances around emotions and decision-making, we evaluate how people's trust and integral emotions function as important antecedents of cognitive evaluations, and subsequent acceptance of policies. We test our hypotheses within a sample of Irish citizens (n = 505), who were subject to the introduction of water charges in 2015. In line with our hypotheses, results show that general trust in government shapes emotions regarding water charges, which in turn, directly and via expected costs and benefits, influence policy acceptance. Additionally, we find that negative emotions have a larger direct effect on policy acceptance than positive emotions. Specifically, 'anger' was the main negative emotion that influenced the acceptance of the water charge. We conclude by discussing directions for future research around emotions and policy acceptance. © 2018 The British Psychological Society.

The research supposes the explanation of influence of stress impulses from an electrical discharge in water on the level of the limited endurance at a cyclic loading of the thermally work-hardened carbon steel. Methodology. Material for research was steel 45 (0,45 % carbon with сoncentration of chemical elements within the limits of steel composition. Specimens for tests are made as plates in 1 thick, width 15 and length 120-180 mm. The structural state of steel corresponded to quenching on a martensite from the normal temperatures of annealing and tempering at 300C, duration of 1 h. Microstructure was investigated with the use of electronic microscopy, the density of dislocations was estimated on the methods of X-ray analysis. Hardness was measured on the method of Rockwell (scale of «C». A cyclic loading was carried out in the conditions of symmetric bend on a tester «Saturn-10» at a temperature +20C. The treatment by shock voltage from the electrical discharge was carried out in water on setting of bath type «Iskra-23», used for cleaning of castings manufactures. Electric impulses were formed at 15-18 kV with energy of 10-12 kJ and amplitude of 1-2 GPа. Findings. As a result of processing pulses of a pressure wave of heat-strengthened steel 45 found the increase of endurance under the cyclic loading corresponds to an increased amount of accumulated dislocations on the fracture surface. The use of Coffin–Manson Equation allowed finding the decrease of deformation per cycle of loading as a result of arising stress from an electrical discharge in water. On the fracture surface (after pulse exposure was found the increased number of dislocations, located in different crystallographic systems, that is a testament to the rather complicated development of dislocation transformations in the structure of steel, which provide an increase of endurance at a fatigue. The increase of the limited endurance became as a result of impulsive

    Polzin, Friedemann; Migendt, Michael; Täube, Florian A.; Flotow, Paschen von

    2015-01-01

    This paper examines the impact of public policy measures on renewable energy (RE) investments in electricity-generating capacity made by institutional investors. Using a novel combination of datasets and a longitudinal research design, we investigate the influence of different policy measures in a sample of OECD countries to suggest an effective policy mix which could tackle failures in the market for clean energy. The results call for technology-specific policies which take into account actual market conditions and technology maturity. To improve the conditions for institutional investments, advisable policy instruments include economic and fiscal incentives such as feed-in tariffs (FIT), especially for less mature technologies. Additionally, market-based instruments such as greenhouse gas (GHG) emission trading systems for mature technologies should be included. These policy measures directly impact the risk and return structure of RE projects. Supplementing these with regulatory measures such as codes and standards (e.g. RPS) and long-term strategic planning could further strengthen the context for RE investments. - Highlights: • Panel data study on the effectiveness of policies to induce RE investments. • Novel combination of datasets (BNEF/IEA) in solar, wind and biomass sectors. • FIT proves to be more effective than subsidies for less mature technologies. • RPS and tradable permit systems seem more effective for mature technologies. • A long-term strategic planning framework is useful to attract institutional investors

    Previous studies have demonstrated that changes in temperature and precipitation (hereafter climate change) would influence river discharge, but the relative importance of climate change, land use, and elevated atmospheric CO2 have not yet been fully investigated. Here we examined how river discharge in the Mississippi River basin in the 21st century might be influenced by these factors using the Dynamic Land Ecosystem Model driven by atmospheric CO2, downscaled GCMs climate and land use scenarios. Our results suggest that river discharge would be substantially enhanced (10.7-59.8%) by the 2090s compared to the recent decade (2000s), though large discrepancies exist among different climate, atmospheric CO2, and land use change scenarios. Our factorial analyses further indicate that the combined effects of land use change and human-induced atmospheric CO2 elevation on river discharge would outweigh climate change effect under the high emission scenario (A2) of Intergovernmental Panel for Climate Change. Our study offers the first attempt to project potential changes in river discharge in response to multiple future environmental changes. It demonstrates the importance of land use change and atmospheric CO2 concentrations in projecting future changes in hydrologic processes. The projected increase river discharge implies that riverine fluxes of carbon, nutrients and pesticide from the MRB to the coastal regions would increase in the future, and thus may influence the states of ocean acidification and hypoxia and deteriorate ocean water quality. Further efforts will also be needed to account for additional environmental factors (such as nitrogen deposition, tropospheric ozone pollution, dam construction, etc.) in projecting changes in the hydrological cycle.

    Policy entrepreneurs are individuals who attempt to influence the policy process and its outcomes through their opportunistic or incremental actions. Their success in the policy-making process has been associated with the convergence of four factors: behavioural traits; institutional factors; network position and political capital. Policy entrepreneurs have received little study in low- and middle-income country policy research despite observations of individualized decision-making, informal institutions and the unequal distribution and exercise of power in policymaking. This article aims to identify whether policy entrepreneurs were present in the policy process around integrated community case management (iCCM) in Burkina Faso, whether they were successful in achieving policy change, and whether success or failure can be explained using existing policy entrepreneur frameworks from high-income polities. This mixed methods policy study collected data from in-depth qualitative interviews and social network surveys of actors involved in iCCM policymaking [known locally as C-integrated management of childhood illness (IMCI)]; data were analysed based on the framework categories. Interview data pointed to one key individual who played a significant role in the inclusion of pneumonia treatment into the country's iCCM policy, an issue that had been a point of contention between government policy elites and development partners. Social network data confirmed that this actor was strategically located in the policy network to be able to reach the most other actors and to be able to control the flow of information. Although some development partner actors were as strategically located, none had the same level of authority or trust as was imbued by being a member of the government civil service. The entrepreneur's mid-level rank in the health ministry may have encouraged him/her to invest political capital and take risks that would not have been feasible or attractive to a

    Full Text Available Abstract Background The interface between research and policymaking in low-income countries is highly complex. The ability of health systems research to influence policy processes in such settings face numerous challenges. Successful analysis of the research-policy interface in these settings requires understanding of contextual factors as well as key influences on the interface. Future Health Systems (FHS: Innovations for Equity is a consortium conducting research in six countries in Asia and Africa. One of the three cross-country research themes of the consortium is analysis of the relationship between research (evidence and policy making, especially their impact on the poor; insights gained in the initial conceptual phase of FHS activities can inform the global knowledge pool on this subject. Discussion This paper provides a review of the research-policy interface in low-income countries and proposes a conceptual framework, followed by directions for empirical approaches. First, four developmental perspectives are considered: social institutional factors; virtual versus grassroots realities; science-society relationships; and construction of social arrangements. Building on these developmental perspectives three research-policy interface entry points are identified: 1. Recognizing policy as complex processes; 2. Engaging key stakeholders: decision-makers, providers, scientists, and communities; and 3. Enhancing accountability. A conceptual framework with three entry points to the research-policy interface – policy processes; stakeholder interests, values, and power; and accountability – within a context provided by four developmental perspectives is proposed. Potential empirical approaches to the research-policy interface are then reviewed. Finally, the value of such innovative empirical analysis is considered. Conclusion The purpose of this paper is to provide the background, conceptual framework, and key research directions for

  18. An Empirical Analysis of Stakeholders' Influence on Policy Development: the Role of Uncertainty Handling

    2011-03-01

    Full Text Available Stakeholder participation is advocated widely, but there is little structured, empirical research into its influence on policy development. We aim to further the insight into the characteristics of participatory policy development by comparing it to expert-based policy development for the same case. We describe the process of problem framing and analysis, as well as the knowledge base used. We apply an uncertainty perspective to reveal differences between the approaches and speculate about possible explanations. We view policy development as a continuous handling of substantive uncertainty and process uncertainty, and investigate how the methods of handling uncertainty of actors influence the policy development. Our findings suggest that the wider frame that was adopted in the participatory approach was the result of a more active handling of process uncertainty. The stakeholders handled institutional uncertainty by broadening the problem frame, and they handled strategic uncertainty by negotiating commitment and by including all important stakeholder criteria in the frame. In the expert-based approach, we observed a more passive handling of uncertainty, apparently to avoid complexity. The experts handled institutional uncertainty by reducing the scope and by anticipating windows of opportunity in other policy arenas. Strategic uncertainty was handled by assuming stakeholders' acceptance of noncontroversial measures that balanced benefits and sacrifices. Three other observations are of interest to the scientific debate on participatory policy processes. Firstly, the participatory policy was less adaptive than the expert-based policy. The observed low tolerance for process uncertainty of participants made them opt for a rigorous "once and for all" settling of the conflict. Secondly, in the participatory approach, actors preferred procedures of traceable knowledge acquisition over controversial topics to handle substantive uncertainty. This

    This work is devoted to the evolution of the competition of energy alternative pathway in China, and the influence of energy policy on economic growth by using a dynamical system method. Firstly, the relation between energy and economic growth is taken into account, and a dynamic evolution model is established. It is observed that Hopf bifurcation and chaotic behavior occurs with the varying investment in renewable energy production. Secondly, when there is no policy intervention in energy market, the evolution of competition in energy alternative pathway is also investigated. Thirdly, the system parameters are also identified by using an artificial neural network method on the basis of certain empirical statistical data in China, and the dynamics of the parameters-identified system are studied. Finally, the influences of energy policy on economic growth are empirically analyzed, and some policy recommendations are given based on the results of empirical analysis. - Highlights: • Modeling the energy economy system via the method of dynamic system. • Attaining the chaotic attractor of the energy production and economic system. • Discovering the Hopf bifurcation when the investment changes. • Proposing the alternative pathway of free competition in energy production. • Determining the turning points of parameters related to policy regulation

  20. Influence of export control policy on the competitiveness of machine tool producing organizations

    Ahrstrom, Jeffrey D.

    The possible influence of export control policies on producers of export controlled machine tools is examined in this quantitative study. International market competitiveness theories hold that market controlling policies such as export control regulations may influence an organization's ability to compete (Burris, 2010). Differences in domestic application of export control policy on machine tool exports may impose throttling effects on the competitiveness of participating firms (Freedenberg, 2010). Commodity shipments from Japan, Germany, and the United States to the Russian market will be examined using descriptive statistics; gravity modeling of these specific markets provides a foundation for comparison to actual shipment data; and industry participant responses to a user developed survey will provide additional data for analysis using a Kruskal-Wallis one-way analysis of variance. There is scarce academic research data on the topic of export control effects within the machine tool industry. Research results may be of interest to industry leadership in market participation decisions, advocacy arguments, and strategic planning. Industry advocates and export policy decision makers could find data of interest in supporting positions for or against modifications of export control policies.

    Public health leaders in Yellowstone County, Montana, formed an alliance to address community-wide issues. One such issue is Complete Streets, with its vision of safe streets for all. This case study focuses on development and adoption of a Complete Streets policy. It examines how a community coalition, Healthy By Design, infused a gender focus into the policymaking process. An incremental and nonlinear policymaking process was aided by a focus on gender and health equity. The focus on a large constituency helped to frame advocacy in terms of a broad population's needs, not just special interests. The city council unanimously adopted a Complete Streets resolution, informed by a gender lens. Healthy By Design further used gender information to successfully mobilize the community in response to threats of repeal of the policy, and then influenced the adoption of a revised policy. Policies developed with a focus on equity, including gender equity, may have broader impact on the community. Such policies may pave the way for future policies that seek to transform gender norms toward building a healthier community for all residents. Published by Elsevier Inc.

    The results of the Balmer alfa line shape study in a plane cathode-hollow anode Grimm discharge with aluminum (Al) cathode covered with thin layer of porous Al 2 O 3 are presented. The comparison with same line profile recorded with pure Al cathode shows lack of excessive Doppler broadened line wings, which are always detected in glow discharge with metal cathode. The effect is explained by the lack of strong electric field in the cathode sheath region, which is missing in the presence of thin oxide layer in, so called, spray discharge.

  4. Between reason and coercion: ethically permissible influence in health care and health policy contexts.

    2012-12-01

    In bioethics, the predominant categorization of various types of influence has been a tripartite classification of rational persuasion (meaning influence by reason and argument), coercion (meaning influence by irresistible threats-or on a few accounts, offers), and manipulation (meaning everything in between). The standard ethical analysis in bioethics has been that rational persuasion is always permissible, and coercion is almost always impermissible save a few cases such as imminent threat to self or others. However, many forms of influence fall into the broad middle terrain-and this terrain is in desperate need of conceptual refining and ethical analysis in light of recent interest in using principles from behavioral science to influence health decisions and behaviors. This paper aims to address the neglected space between rational persuasion and coercion in bioethics. First, I argue for conceptual revisions that include removing the "manipulation" label and relabeling this space "nonargumentative influence," with two subtypes: "reason-bypassing" and "reason-countering." Second, I argue that bioethicists have made the mistake of relying heavily on the conceptual categories themselves for normative work and instead should assess the ethical permissibility of a particular instance of influence by asking several key ethical questions, which I elucidate, that relate to (1) the impact of the form of influence on autonomy and (2) the relationship between the influencer and the influenced. Finally, I apply my analysis to two examples of nonargumentative influence in health care and health policy: (1) governmental agencies such as the Food and Drug Administration (FDA) trying to influence the public to be healthier using nonargumentative measures such as vivid images on cigarette packages to make more salient the negative effects of smoking, and (2) a physician framing a surgery in terms of survival rates instead of mortality rates to influence her patient to consent to

    The United States has often led the world in supporting renewable energy technologies at both the state and federal level. However, since 2011 several states have weakened their renewable energy policies. Public opinion will probably be crucial for determining whether states expand or contract their renewable energy policies in the future. Here we show that a majority of the public in most states supports renewable portfolio standards, which require a portion of the electricity mix to come from renewables. However, policy design and framing can strongly influence public support. Using a survey experiment, we show that effects of renewable portfolio standards bills on residential electricity costs, jobs and pollution, as well as bipartisan elite support, are all important drivers of public support. In many states, these bills' design and framing can push public opinion above or below majority support.

  6. Discharge modulates stream metabolism dependence on fine particulate organic carbon in a Mediterranean WWTP-influenced stream

    Waste water treatment plant (WWTP) effluents constitute point source inputs of fine sediment, nutrients, carbon, and microbes to stream ecosystems. A range of responses to these inputs may be observed in recipient streams, including increases in respiration rates, which augment CO2 emissions to the atmosphere. Yet, little is known about which fractions of organic carbon (OC) contribute the most to stream metabolism in WWTP-influenced streams. Fine particulate OC (POC) represents ca. 40% of the total mass of OC in river networks, and is generally more labile than dissolved OC. Therefore, POC inputs from WWTPs could contribute disproportionately to higher rates of heterotrophic metabolism by stream microbial communities. The aim of this study was to investigate the influence of POC inputs from a WWTP effluent on the metabolism of a Mediterranean stream over a wide range of hydrologic conditions. We hypothesized that POC inputs would have a positive effect on respiration rates, and that the response to POC availability would be larger during low flows when the dilution capacity of the recipient stream is negligible. We focused on the easily resuspended fine sediment near the sediment-water interface (top 3 cm), as this region is a known hot spot for biogeochemical processes. For one year, samples of resuspended sediment were collected bimonthly at 7 sites from 0 to 800 m downstream of the WWTP point source. We measured total POC, organic matter (OM) content (%), and the associated metabolic activity of the resuspended sediment using the resazurin-resorufin smart tracer system as a proxy for aerobic ecosystem respiration. Resuspended sediment showed no difference in total POC over the year, while the OM content increased with decreasing discharge. This result together with the decreasing trend of total POC observed downstream of the point source during autumn after a long dry period, suggests that the WWTP effluent was the main contributor to stream POC. Furthermore

    The US Department of Agriculture recently issued an interim final rule governing the sale of foods and beverages sold outside of the school meal programs ("competitive foods and beverages" [CF&Bs]). To examine the potential influence that the federal rule may have based on peer-reviewed published studies examining the relationship between state laws and/or school district policies and student body mass index (BMI) and weight outcomes, consumption, and availability of CF&Bs. Keyword searches of peer-reviewed literature published between January 2005 and March 2013 were conducted using multiple databases. Titles and abstracts for 1160 nonduplicate articles were reviewed, with a full review conducted on 64 of those articles to determine their relevancy. Qualitative studies, studies of self-reported policies, or studies examining broad policies without a specific CF&B element were excluded. Twenty-four studies were selected for inclusion. Studies focused on state laws (n = 14), district policies (n = 8), or both (n = 2), with the majority of studies (n = 18) examining foods and beverages (as opposed to food-only or beverage-only policies). Sixteen studies examined prepolicy/postpolicy changes, and 8 studies examined postpolicy changes. Study designs were cross-sectional (n = 20), longitudinal (n = 3), or a combination (n = 1). Outcomes examined included change in BMI, weight, probability of overweight or obesity (n = 4), consumption (n = 10), and availability (n = 13); 3 studies examined more than 1 outcome. The majority of studies primarily reported results in the expected direction (n = 15), with the remaining studies (n = 9) reporting primarily mixed or nonsignificant results. In most cases, CF&B policies are associated with changes in consumption and/or availability in the expected direction; however, caution should be exercised, given that nearly all were cross-sectional. The influence of such policies on overall

    Following a shooting incident where a vehicle is used to convey the culprits to and from the scene, both the getaway car and the firearm are often deliberately burned in an attempt to destroy any forensic evidence which may be subsequently recovered. Here we investigate the factors that influence the ability to make toolmark identifications on ammunition discharged from pistols recovered from such car fires. This work was carried out by conducting a number of controlled furnace tests in conjunction with real car fire tests in which three 9mm semi-automatic pistols were burned. Comparisons between pre-burn and post burn test fired ammunition discharged from these pistols were then performed to establish if identifications were still possible. The surfaces of the furnace heated samples and car fire samples were examined following heating/burning to establish what factors had influenced their surface morphology. The primary influence on the surfaces of the furnace heated and car fire samples was the formation of oxide layers. The car fire samples were altered to a greater extent than the furnace heated samples. Identifications were still possible between pre- and post-burn discharged cartridge cases, but this was not the case for the discharged bullets. It is suggested that the reason for this is a difference between the types of firearms discharge-generated toolmarks impressed onto the base of cartridge cases compared to those striated along the surfaces of bullets. It was also found that the temperatures recorded in the front foot wells were considerably less than those recorded on top of the rear seats during the car fires. These factors should be assessed by forensic firearms examiners when performing casework involving pistols recovered from car fires. Copyright © 2016 The Chartered Society of Forensic Sciences.

    Carrying abundant nutrition, terrigenous freshwater has a great impact on the spatial and temporal heterogeneity of phytoplankton in coastal waters. The present study analyzed the spatial-temporal variations of Chlorophyll-a (Chl-a) concentration under the influence of discharge from the Yangtze River, based on remotely sensed Chl-a concentrations. The study area was initially zoned to quantitatively investigate the spatial variation patterns of Chl-a. Then, the temporal variation of Chl-a in each zone was simulated by a sinusoidal curve model. The results showed that in the inshore waters, the terrigenous discharge was the predominant driving force determining the pattern of Chl-a, which brings the risk of red tide disasters; while in the open sea areas, Chl-a was mainly affected by meteorological factors. Furthermore, a diversity of spatial and temporal variations of Chl-a existed based on the degree of influences from discharge. The diluted water extended from inshore to the east of Jeju Island. This process affected the Chl-a concentration flowing through the area, and had a potential impact on the marine environment. The Chl-a from September to November showed an obvious response to the discharge from July to September with a lag of 1 to 2 months. PMID:26006121

    There is increasing recognition that the development of evidence-informed health policy is not only a technical problem of knowledge exchange or translation, but also a political challenge. Yet, while political scientists have long considered the nature of political systems, the role of institutional structures, and the political contestation of policy issues as central to understanding policy decisions, these issues remain largely unexplored by scholars of evidence-informed policy making. We conducted a systematic review of empirical studies that examined the influence of key features of political systems and institutional mechanisms on evidence use, and contextual factors that may contribute to the politicisation of health evidence. Eligible studies were identified through searches of seven health and social sciences databases, websites of relevant organisations, the British Library database, and manual searches of academic journals. Relevant findings were extracted using a uniform data extraction tool and synthesised by narrative review. 56 studies were selected for inclusion. Relevant political and institutional aspects affecting the use of health evidence included the level of state centralisation and democratisation, the influence of external donors and organisations, the organisation and function of bureaucracies, and the framing of evidence in relation to social norms and values. However, our understanding of such influences remains piecemeal given the limited number of empirical analyses on this subject, the paucity of comparative works, and the limited consideration of political and institutional theory in these studies. This review highlights the need for a more explicit engagement with the political and institutional factors affecting the use of health evidence in decision-making. A more nuanced understanding of evidence use in health policy making requires both additional empirical studies of evidence use, and an engagement with theories and approaches

    To examine the influence of state laws and district policies on district-wide elementary school and middle school practices related to physical education (PE) time and the percentage of moderate-to-vigorous physical activity (MVPA) time during PE. Multivariate, cross-sectional analysis of state laws, district wellness and PE policies, and district PE practices for school year 2010-2011 controlling for district-level urbanicity, region, size, race/ethnicity of students, and socioeconomic status and clustered on state. One hundred ninety-five public school districts located in 42 states. District-level PE coordinators for the included districts who responded to an online survey. Minutes and days of PE per week and percent time spent in MVPA during PE time. District PE coordinators reported significantly less PE time than national standards-82.9 and 189.6 minutes at the elementary school and middle school levels, respectively. Physical education was provided an average of 2.5 and 3.7 days per week, respectively; and the percentage of MVPA time in PE was 64.4% and 65.7%, respectively. At the elementary school level, districts in either states with laws governing PE time or in a state and district with a law/policy reported significantly more days of PE (0.63 and 0.67 additional days, respectively), and districts in states with PE time laws reported 18 more minutes of PE per week. At the middle school level, state laws were associated with 0.73 more days of PE per week. Neither state laws nor district policies were positively associated with percent MVPA time in PE. State laws and district policies can influence district-level PE practices-particularly those governing the frequency and duration of PE-although opportunities exist to strengthen PE-related laws, policies, and practices.

    The use of attaching gases in an externally sustained diffuse discharge opening switch with a low attachment rate at low values of E/N and a high attachment rate at high values of E/N allows the discharge to operate with low losses in the closed switch phase and to achieve fast opening after the sustainment source is turned off. Such an attacher generates a J-E/N characteristic with a negative differential conductivity in an intermediate E/N range. Such a characteristic obstructs the closing process of the discharge if it is operated in a high impedance system. Experiments demonstrating these effects are presented for electron beam sustained discharges in mixtures of argon and C 2 F 6

    Full Text Available Problems related to alcohol consumption are frequent, especially among young people. Alcohol beverage advertisements influence its consumption and is one of the liable to modification factors. In this work, it was carried out a bibliographical review of works that investigated, from several points of view, the relationship between media and consumption. We have used Scielo database and Google Academic for scientific works, searching for the keywords media, alcohol consumption and advertising, as well as articles and books of reference in the area. The reading of the texts has allowed us to reflect on the influence of media in alcohol consumption, and we can also verify the high exposition of youth to alcohol advertisements, becoming relevant a discussion on the subject, particularly regarding protection policies, as well as self-regulamentation advertising rules in public health policies.

    This paper presents simulations of an atmospheric pressure air discharge in a point-to-plane geometry with a dielectric layer parallel to the cathode plane. Experimentally, a discharge reignition in the air gap below the dielectrics has been observed. With a 2D fluid model, it is shown that due to the fast rise of the high voltage applied and the sharp point used, a first positive spherical discharge forms around the point. Then this discharge propagates axially and impacts the dielectrics. As the first discharge starts spreading on the upper dielectric surface, in the second air gap with a low preionization density of {{10}4}~\\text{c}{{\\text{m}}-3} , the 2D fluid model predicts a rapid reignition of a positive discharge. As in experiments, the discharge reignition is much slower, a discussion on physical processes to be considered in the model to increase the reignition delay is presented. The limit case with no initial seed charges in the second air gap has been studied. First, we have calculated the time to release an electron from the cathode surface by thermionic and field emission processes for a work function φ \\in ≤ft[3,4\\right] eV and an amplification factor β \\in ≤ft[100,220\\right] . Then a 3D Monte Carlo model has been used to follow the dynamics of formation of an avalanche starting from a single electron emitted at the cathode. Due to the high electric field in the second air gap, we have shown that in a few nanoseconds, a Gaussian cloud of seed charges is formed at a small distance from the cathode plane. This Gaussian cloud has been used as the initial condition of the 2D fluid model in the second air gap. In this case, the propagation of a double headed discharge in the second air gap has been observed and the reignition delay is in rather good agreement with experiments.

  15. Gifts and influence: Conflict of interest policies and prescribing of psychotropic medications in the United States.

    The pharmaceutical industry spends roughly 15 billion dollars annually on detailing - providing gifts, information, samples, trips, honoraria and other inducements - to physicians in order to encourage them to prescribe their drugs. In response, several states in the United States adopted policies that restrict detailing. Some states banned gifts from pharmaceutical companies to doctors, other states simply required physicians to disclose the gifts they receive, while most states allowed unrestricted detailing. We exploit this geographic variation to examine the relationship between gift regulation and the diffusion of four newly marketed medications. Using a dataset that captures 189 million psychotropic prescriptions written between 2005 and 2009, we find that uptake of new costly medications was significantly lower in states with marketing regulation than in areas that allowed unrestricted pharmaceutical marketing. In states with gift bans, we observed reductions in market shares ranging from 39% to 83%. Policies banning or restricting gifts were associated with the largest reductions in uptake. Disclosure policies were associated with a significantly smaller reduction in prescribing than gift bans and gift restrictions. In states that ban gift-giving, peer influence substituted for pharmaceutical detailing when a relatively beneficial drug came to market and provided a less biased channel for physicians to learn about new medications. Our work suggests that policies banning or limiting gifts from pharmaceutical representatives to doctors are likely to be more effective than disclosure policies alone. Copyright © 2016 Elsevier Ltd.

  16. The (limited) political influence of ecological economics. A case study on Dutch environmental policies

    2010-01-01

    Although the ecological economics (EE) discourse attempts to influence environmental policy, empirical studies have concluded that its success in this endeavour has been limited thus far. In the Netherlands, however, two EE-related policy concepts, Environmental Utilisation Space and Ecological Footprint, were strongly present in environmental policy during certain periods in time, but subsequently disappeared from the environmental agenda. The central question of this article is how these ups and downs of the EE concepts can be understood: which factors determine their rise on and fall from the policy agenda over time? To answer this question, this article offers a conceptual model informed by the approaches in political science on framing, agenda-setting and knowledge utilisation. We conclude that the interplay of concept-specific characteristics, the formation of coalitions around the concept and contextual variables explain the rise and fall of the aforementioned concepts. A match between the dominant policy frame and the core elements of the concept provides the opportunity for the two concepts to be pushed on the agenda. We observe the alternation of 'constraining' frames, which allows for EE concepts to survive, and 'reconciling' frames, which block agenda entrance for EE concepts. Furthermore, the alternation of these frames seems to correlate with economic and public environmental attention cycles in the Netherlands. (author)

  17. Influence of smallholder farmers’ perceptions on adaptation strategies to climate change and policy implications in Zimbabwe

    2017-01-01

    Full Text Available Smallholder agricultural production is largely affected by climate change and variability. Despite the negative effects brought by climate variability, smallholder farmers are still able to derive livelihoods. An understanding of factors that influence farmers’ responses and adaptation to climate variability can improve decision making for governments and development partners. This study investigated farmers’ perceptions and adaptation strategies to climate change and how these influence adaptation policies at local level. A survey was conducted with 100 households randomly selected from Chiredzi district. Data collected was used to derive farmer perceptions to climate change as well as the influence of their perceptions and subsequent adaptation methods to ensuing local agricultural adaptation measures and policies. The results indicated that smallholder farmers perceived general reduction in long-term annual rainfall and rising local average temperatures. Adverse trends in rainfall and average temperature perceived by farmers were consistent with empirical data. These perceptions and other socio-economic factors helped to shape smallholder farmer agricultural adaptation strategies. Policy implications are that the government and development partners should seek ways to assist autonomous adaptations by farmers through investments in planned adaptation initiatives.

    The carbon chemistry of coral reef lagoons can be highly variable over short time scales. While much of the diel variability in seawater carbon chemistry is explained by biological processes, external sources such as river and groundwater seepage may deliver large amounts of organic and inorganic carbon to coral reefs and represent a poorly understood feedback to ocean acidification. Here, we assess the impact of submarine groundwater discharge (SGD) on pCO2 variability in two coral reef lagoons with distinct SGD driving mechanisms. Diel variability of pCO2 in the two ecosystems was explained by a combination of biological drivers and SGD inputs. In Rarotonga, a South Pacific volcanic island, SGD was driven primarily by a steep terrestrial hydraulic gradient, and the lagoon was influenced by the high pCO2 (5,501 μatm) of the fresh groundwater. In Heron Island, a Great Barrier Reef coral cay, SGD was dominated by seawater recirculation through sediments (i.e. tidal pumping) and pCO2 was mainly impacted through the stimulation of biological processes. The Rarotonga water column had a relatively higher average pCO2 (549 μatm) than Heron Island (471 μatm). However, pCO2 exhibited a greater diel range in Heron Island (778 μatm) than in Rarotonga (507 μatm). The Rarotonga lagoon received 31.2 mmol CO2 m-2 d-1 from SGD, while the Heron Island lagoon received 12.3 mmol CO2 m-2 d-1. Over the course of this study both systems were sources of CO2 to the atmosphere (3.00 to 9.67 mmol CO2 m-2 d-1), with SGD-derived CO2 contributing a large portion to the air-sea CO2 flux. The relationship between both water column pH and aragonite saturation state (ΩAr) and radon (222Rn) concentrations indicate that SGD may enhance the local acidification of some coral reef lagoons. Studies measuring the carbon chemistry of coral reefs (e.g. community metabolism, calcification rates) may need to consider SGD-derived CO2.

    To develop a theory that explains the process of how teachers' perception of multilevel policies may influence nutrition education (NE) teaching strategies in Head Start preschools. Semistructured telephone interviews. North Carolina Head Start preschools. Thirty-two Head Start teachers. All interviews were transcribed verbatim. Following a grounded theory approach, authors coded interview data for emergent themes. Two primary themes emerged during analysis, including teachers' policy perceptions and teacher-perceived influence of policy on NE. A theoretical model was developed to explain how teachers' perceptions of policies influenced NE (eg, teaching strategies) in the classroom. Teachers discussed multiple policy areas governing their classrooms and limiting their ability to provide meaningful and consistent NE. How teachers perceived the level of regulation in the classroom (ie, high or low) influenced the frequency with which they used specific teaching strategies. Despite federal policies supporting the provision of NE, teachers face competing priorities in the classroom (eg, school readiness vs NE) and policies may conflict with standardized NE curricula. To understand how Head Start centers develop local policies, additional research should investigate how administrators interpret federal and state policies.

    The distribution of hydrogen atoms responsible for emission of the Balmer Hα line in the region of the dielectric barrier discharges in the helium and hydrogen as well as in the argon and hydrogen mixtures, in the direction perpendicular to the electrode surfaces, has bee determined by the optical emission spectroscopy accounting for the polarization of the emitted light. The procedure of fitting the measured line profiles accounting for the Stark effect has been used for determination of the distribution of the electric field in the discharge region

    A mathematical model of ion and sputtered atom transport in the vicinity of the target with a periodical surface relief in glow discharge in pure gas is developed. Under the assumption that the relief amplitude is small, analytical expressions for their flows are found by the perturbation method and an equation describing the relief amplitude time evolution is derived. It is shown that intensity of sputtering exceeds intensity of sputtered material re-deposition at the relief tops, and relief smoothing always takes place in the process of homogeneous target treatment in glow discharge in pure gas

    In the discharge of oscillating electrons, the mechanism of the processes, which controls the distribution of the ion and electron streams over the cathode surface, is investigated experimentally. The influence of the length of the discharge interval on value and distribution of the ion and electron streams is analyzed. The distribution both of ion and electron streams at the cathode surface is determined at different conditions of the discharge. It is shown that for given values of the anode diameter d a =31 mm and the gas pressure P=5x10 -5 Torr, the intensive stream of positive ions falls entirely on the cathode central area in the whole interval of the anode length variation (l a =1-11 cm). At the cathode, the ion current reaches the maximal value at a certain (optimal) value of the anode length that, in turn, depends on the anode voltage U a . The intensive stream of longitudinal electrons forms in the short anodes only (l a =2.5-3.5 cm) and depending on the choice of the discharge regime, may fall both on central and middle parts of the cathode

  4. The Influence of Climate Change Considerations on Energy Policy. The Case of Russia

    To those working on climate change it is obvious that energy policy should be influenced by climate change considerations. The question that this paper seeks to answer is, to what extent do they influence policy and what contribution can a careful analysis of the costs and benefits of climate change options have on the formulation of that policy. We seek to understand this by looking in some detail at energy policy formulation in Russia. To do so it is necessary to look at the whole set of issues that determine energy policy. These include energy security, macroeconomic and uncertainty factors, local environmental issues and social issues. The analysis has been carried out for a specific case - that of the RF, where energy policy is currently under formulation to 2010. Two options have been looked at: a 'High Coal' option, where there would be a substantial change in fuel mix away from gas to coal; and a 'High Gas' option where the current fuel mix is retained and the increase in demand is met from all sources in proportion to current use. The analysis shows that, at international prices for fuels, the 'High Coal' option is attractive. However, when we include the potential decline of price for natural gas in the European market, the relative preference for this option drops dramatically but it still remains the preferred option. When, account is also taken of the carbon benefits of the High Gas option, using plausible values for carbon, the attraction of the High Coal option is further reduced but not altered. When finally account is taken of the health associated with the lower use of coal in the High Gas option, the preference can be reversed but it requires a critical value for the health benefits. This critical value - at around USD 3,000 for a life year lost - is plausible for the RF, if anything the actual value is probably higher. What the analysis shows is the need for a careful evaluation of the different factors determining energy policy. Among these is

  5. Desire or Disease? Framing Obesity to Influence Attributions of Responsibility and Policy Support.

    The way we describe health threats affects perceptions of severity and preferred solutions to reduce risk. Most people agree obesity is a problem, but differ in how they attribute responsibility for development and decline of the disease. We explored effects of message framing on attributions of responsibility and support for public obesity policies using a 3 × 2 factorial design. Participants read one of six versions of a health message describing the negative effects of obesity. Message frames influenced respondent attributions and their support for policies to reduce obesity. Those who read a message that assigned agency to the disease (e.g., Obesity causes health problems) endorsed genetics as the cause to a greater degree than those who read a semantically equivalent message that instead assigned agency to people (e.g., Obese people develop health problems). In contrast, assigning agency to people rather than to the disease prompted higher attributions of individual responsibility and support for public policies. Explicit message frames that directly connected responsibility for obesity to either individual or societal factors had no effect on respondent perceptions. Findings suggest explicit arguments may be less effective in shifting perceptions of health threats than arguments embedded in agentic message frames. The results demonstrate specific message features that influence how people attribute responsibility for the onset and solution of obesity.

    Objectives. We examined the influence of tobacco control policies (tobacco control program expenditures, smoke-free air laws, youth access law compliance, and cigarette prices) on youth smoking outcomes (smoking susceptibility, past-year initiation, current smoking, and established smoking). Methods. We combined data from the 2002 to 2008 National Surveys on Drug Use and Health with state and municipality population data from the US Census Bureau to assess the associations between state tobacco control policy variables and youth smoking outcomes, focusing on youths aged 12 to 17 years. We also examined the influence of policy variables on youth access when these variables were held at 2002 levels. Results. Per capita funding for state tobacco control programs was negatively associated with all 4 smoking outcomes. Smoke-free air laws were negatively associated with all outcomes except past-year initiation, and cigarette prices were associated only with current smoking. We found no association between these outcomes and retailer compliance with youth access laws. Conclusions. Smoke-free air laws and state tobacco control programs are effective strategies for curbing youth smoking. PMID:23327252

  9. The influence of economic interests on alcohol control policy: a case study from Finland.

    Alavaikko, M; Osterberg, E

    2000-12-01

    Finland's participation in the European Union has meant that Finnish markets have been opened to international competition and that the traditional alcohol policy decision-making that revolved around Alko, the state alcohol monopoly company, has become impossible. The influence of private commercial interests increased in the 1990s but not in a straightforward manner. They had their biggest influence in the mid-1990s when the 1994 Alcohol Act was drafted and accepted. After that the influence of commercial interests has declined, and nowadays the alcohol question is again discussed in terms of public health and safety and drinking among young people. Integration did not lead to the expected deregulation of alcohol control but to new forms of regulation, where EU authorities such as the Commission and the EU Court also play an important role. Alcohol policy-making is now more transparent, and free trade and competition without interference are much more stressed than previously. These are the new frames of public intervention in the alcohol question, both in the trade of alcoholic beverages and in the taking care of individuals harmed by the use of alcohol.

    2015-05-01

    Full Text Available Today, consumers do not just buy brands, but also buy company philosophies and policies. Worldwide studies have shown that customers tend to favour companies that are perceived to be socially and environmentally responsible. For that, companies need to face the challenge of evaluating their product and service portfolios, as well as the way these products and services are created, produced and marketed. The question is how to integrate marketing strategy and sustainable development principles for the company success. This paper aims to discover how hard young consumers are influenced in their buying decision by the companies’ preoccupations for sustainable development.

    This work examines the growth dynamics of TiO{sub 2}-SiO{sub 2} nanocomposite coatings in plane-to-plane Dielectric Barrier Discharges (DBDs) at atmospheric pressure operated in a Townsend regime using nebulized TiO{sub 2} colloidal suspension in hexamethyldisiloxane as the growth precursors. For low-frequency (LF) sinusoidal voltages applied to the DBD cell, with voltage amplitudes lower than the one required for discharge breakdown, Scanning Electron Microscopy of silicon substrates placed on the bottom DBD electrode reveals significant deposition of TiO{sub 2} nanoparticles (NPs) close to the discharge entrance. On the other hand, at higher frequencies (HF), the number of TiO{sub 2} NPs deposited strongly decreases due to their “trapping” in the oscillating voltage and their transport along the gas flow lines. Based on these findings, a combined LF-HF voltage waveform is proposed and used to achieve significant and spatially uniform deposition of TiO{sub 2} NPs across the whole substrate surface. For higher voltage amplitudes, in the presence of hexamethyldisiloxane and nitrous oxide for plasma-enhanced chemical vapor deposition of inorganic layers, it is found that TiO{sub 2} NPs become fully embedded into a silica-like matrix. Similar Raman spectra are obtained for as-prepared TiO{sub 2} NPs and for nanocomposite TiO{sub 2}-SiO{sub 2} coating, suggesting that plasma exposure does not significantly alter the crystalline structure of the TiO{sub 2} NPs injected into the discharge.

    The alterations induced in the ambient temperature can lead to wide manifestations in species distribution and community structure. In general, elevated water temperature causes changes in species composition, species dominance, standing crop and productivity of biota including phytoplankton communities in any aquatic ecosystem. Thus warm water discharges from power plants into the receiving water bodies may adversely affect aquatic ecology. In the absence of exhaustive data on the response of aquatic organisms and ecosystems in the tropics to elevated temperatures, the only option is to draw inferences, from the experiences in the subtropical and temperature areas. Since, sufficient data on similar line are not available in tropical environment, present paper delineates certain aspects of aquatic ecology of the Kadra reservoir where cooling water is discharged. The study suggests the heated effluents from Kaiga Nuclear Power plant caused changes in dissolved oxygen and pH of water, heterotrophic bacterial population, sediment biogeochemical cycles related biochemical processes, species composition, species dominance, standing crop and productivity of biota including phytoplankton communities within 500 m from End of Discharge Canal point of Kadra reservoir when two units are running in full capacity.

    The barrier glow discharge between two planar electrodes, covered with dielectric, is studied under high-voltage pulsed power supply. Wide applications of such type of discharges, in particular, for ozone production, stimulated a number of investigations in this direction. In this work we investigated the dependence of ozone concentration on the duration and the rate of pulse rise of the applied voltage. The thyristor converter circuit with the shortening of input pulses on the base of the saturable throttle was used for the realization of this task. The output pulses with amplitude up to 15 kV, repetition frequency of 1 kHz, pulse duration of 0.3 μs (or 7 μs) and the rate of pulse rise of 0.1 μs were generated with this scheme. Measurements of the ozone concentration produced in the air mixture have shown that its value increased by factor two with variation of the rate of pulse rise from 0.5 μs to 0.1 μs (for pulse duration of 7 μs). The dependence of the ozone concentration on the variation of air mixture pressure in the discharge gap of reactor was investigated also. It was shown proportional increase of the output concentration of ozone with increasing the pressure value. Spectroscopic measurements carried out in the ultraviolet spectrum made it possible to analyze changing the concentration of ozone and nitric components. (author)

  15. Local Interpretations of Degrowth—Actors, Arenas and Attempts to Influence Policy

    Full Text Available During the last decade, degrowth has developed into a central research theme within sustainability science. A significant proportion of previous works on degrowth has focused on macro-level units of analysis, such as global or national economies. Less is known about local interpretations of degrowth. This study explored interpretations of growth and degrowth in a local setting and attempts to integrate degrowth ideas into local policy. The work was carried out as a qualitative single-case study of the small town of Alingsås, Sweden. The results revealed two different, yet interrelated, local growth discourses in Alingsås: one relating to population growth and one relating to economic growth. Individuals participating in the degrowth discourse tend to have a sustainability-related profession and/or background in civil society. Arenas for local degrowth discussions are few and temporary and, despite some signs of influence, degrowth-related ideas have not had any significant overall impact on local policy and planning. In practice, degrowth-interested individuals tend to adjust their arguments to the mainstream sustainability discourse and turn to arenas beyond the formal municipal organization when discussing transformative ideas about development, progress, and quality of life. Based on these findings, the conditions for a further integration of degrowth into local policy and planning are discussed. Suggested themes for further research are institutional change and the role of local politicians.

  16. Numerical study of the influence of dielectric tube on propagation of atmospheric pressure plasma jet based on coplanar dielectric barrier discharge

    2018-05-01

    A 2D fluid model was employed to simulate the influence of dielectric on the propagation of atmospheric pressure helium plasma jet based on coplanar dielectric barrier discharge (DBD). The spatio-temporal distributions of electron density, ionization rate, electrical field, spatial charge and the spatial structure were obtained for different dielectric tubes that limit the helium flow. The results show that the change of the relative permittivity of the dielectric tube where the plasma jet travels inside has no influence on the formation of DBD itself, but has great impact on the jet propagation. The velocity of the plasma jet changes drastically when the jet passes from a tube of higher permittivity to one of lower permittivity, resulting in an increase in jet length, ionization rate and electric field, as well as a change in the distribution of space charges and discharge states. The radius of the dielectric tube has a great influence on the ring-shaped or solid bullet structure. These results can well explain the behavior of the plasma jet from the dielectric tube into the ambient air and the hollow bullet in experiments.

    Objective The Indigenous Burden of Disease (IBoD) report is the most comprehensive assessment of Indigenous disease burden in Australia. The aim of the present study was to investigate the potential effect of the IBoD report on Australian Indigenous health policy, service expenditure and research funding. Findings have significance for understanding factors that may influence Indigenous health policy. Methods The potential effect of the IBoD report was considered by: (1) conducting a text search of pertinent documents published by the federal government, Council of Australian Governments and the National Health and Medical Research Council of Australia (NHMRC) and observing the quantity and quality of references to IBoD; (2) examining data on government Indigenous healthcare expenditure for trends consistent with the findings and policy implications of the IBoD report; and (3) examining NHMRC Indigenous grant allocation trends consistent with the findings and policy implications of the IBoD report. Results Of 110 government and NHMRC documents found, IBoD was cited in 27. Immediately after publication of the IBoD report, federal and state governments increased Indigenous health spending (relative to non-Indigenous), notably for community health and public health at the state level. Expenditure on Indigenous hospital separations for chronic diseases also increased. These changes are broadly consistent with the findings of the IBoD report on the significance of chronic disease and the need to address certain risk factors. However, there is no evidence that such changes had a causal connection with the IBoD study. After publication of the IBoD report, changes in NHMRC Indigenous research funding showed little consistency with the findings of the IBoD report. Conclusions The present study found only indirect and inconsistent correlational evidence of the potential influence of the IBoD report on Indigenous health expenditure and research funding.

    The influence of electrical discharge machining (EDM) on the abrasive wear resistance of two WC-10 %{sub w}tCo cemented carbides with different carbide grain size has been studied. Different surface finish conditions were evaluated corresponding to sequential EDM as well as grinding and polishing with diamond. The abrasive wear resistance was determined through microscratch measurements using a nano indentation system. Contrary to the results obtained from hardness measurements, this techniques allows to discern tribological differences among the distinct surface finish conditions studied. Finally, the abrasive wear resistance degradation associated with sequential EDM is discussed as a function of microstructure in terms of a damage parameters. (Author) 9 refs.

    Influence of the elongated dust cloud on the intensities of different neon spectral lines in visible and near ir spectral ranges in the uniform positive column has been experimentally investigated using the Russian-European space apparatus “Plasma Kristall-4” (SA PK-4) on board of the International Space Station (ISS). The investigation was performed in the low pressure (0.5 mbar) direct current (dc, 1 mA) gas discharge in neon. Microgravity allowed us to perform experiments with a large dust cloud in the steady-state regime. To avoid the dust cloud drift in the dc electric field a switching dc polarity discharge mode has been applied. During the experiment a dust cloud of 9 mm in diameter in the discharge tube of 30 mm in diameter with the length of about 100 mm has been observed in the steady-state regime. In this regard, the intensities of neon spectral lines corresponding to 3p → 3s electronic transitions have increased by a factor of 1.4 times, while the intensities of neon spectral lines corresponding to 3d → 3p electronic transitions have increased by a factor of 1.6 times. The observed phenomenon is explained on the basis of the Schottky approach by a self-consistent rising dc electric field in the dusty plasma cloud resulting in an increase of the electron temperature.

  20. Modelling electric discharge chemistry

    The chemistry occurring in a electric discharge was modelled to predict how it would be influenced by discharge conditions. The discharge was characterized by a calculated Boltzmann electron-energy distribution, from which rate constants for electron-molecule processes in air were determined. These rate constants were used in a chemical kinetics calculation that also included reactions between neutral molecules, ions, free radicals and electronically excited species. The model describes how the discharge chemistry was influenced by humidity, electric field, electron number density, and concentrations of key reagents identified in the study. The use of an electric discharge to destroy airborne contaminant molecules was appraised, the targeted contaminants being CF 2 Cl 2 , HCN, and SO 2 . The modelling results indicate that an electric discharge should be able to remove HCN and CF 2 Cl 2 effectively, especially if the discharge conditions have been optimized. Effective destruction is achieved with a moderate electric field (over 1 x 10 -15 V.cm 2 ), a substantial electron number density (over 1 x 10 12 cm -3 ), and the presence of H 2 0 in the process air. The residence time in the discharge was also shown to be important in contaminant destruction. An attempt was made to explain the results of the electric discharge abatement of SO 2 , a component of a simulated flue-gas mixture. Results from the model indicate that the discharge parameters that increase the concentration of hydroxyl radical also increase the rate of decomposition of SO 2 . An objective of the study was to explain the apparent enhancement of SO 2 destruction by the presence of a small amount of NO 2 . It was thought that a likely explanation would be the stabilization of HOSO 2 , an important intermediate in the oxidation of SO 2 by NO 2 . (49 figs., 14 tabs., 75 refs.)

    The aim of this study was to investigate 12 perfluorinated compounds (PFCs) including perfluorinated carboxylates (C4–C12) and perfluorinated alkyl sulfonates (C4, C6, and C8) in river and seawater samples to determine contamination levels in the aquatic environment of Hyogo prefecture, Japan. High levels of perfluorohexanoic acid (PFHxA; 2300–16,000 ng/L) were detected in the Samondogawa River at Tatsumi Bridge downstream of a PFC production facility; this location also had the highest mass flow rate of PFCs (3900–29,000 kg/y). Widespread contamination of coastal waters was confirmed with PFHxA as the dominant compound. Perfluorooctanoic acid was also prevalent in coastal waters. The concentration of PFHxA in coastal seawater and the distance from the mouth of the Samondogawa River were inversely related. This discharge of high concentrations of PFHxA from the Samondogawa River may have affected concentrations of PFCs in Osaka Bay. -- Highlights: • High perfluorohexanoic acid concentration was detected in the Samondogawa River. • The mass flow rate of PFCs in this river section was 3900–29,000 kg/y. • Perfluorohexanoic acid was the dominant compound at all seawater sampling sites. • Perfluorohexanoic acid from the Samondogawa River may have affected Osaka Bay. -- Discharge of perfluorohexanoic acid from the Samondogawa River may have affected Osaka Bay

    This paper describes the modeling work by Makai Ocean Engineering, Inc. to simulate the biochemical effects of of the nutrient-enhanced seawater plumes that are discharged by one or several 100 megawatt OTEC plants. The modeling is needed to properly design OTEC plants that can operate sustainably with acceptably low biological impact. In order to quantify the effect of discharge configuration and phytoplankton response, Makai Ocean Engineering implemented a biological and physical model for the waters surrounding O`ahu, Hawai`i, using the EPA-approved Environmental Fluid Dynamics Code (EFDC). Each EFDC grid cell was approximately 1 square kilometer by 20 meters deep, and used a time step of three hours. The biological model was set up to simulate the biochemical response for three classes of organisms: Picoplankton (< 2 um) such as prochlorococccus, nanoplankton (2-20 um), and microplankton (> 20 um) e.g., diatoms. The dynamic biological phytoplankton model was calibrated using chemical and biological data collected for the Hawaii Ocean Time Series (HOTS) project. Peer review of the biological modeling was performed. The physical oceanography model uses boundary conditions from a surrounding Hawai'i Regional Ocean Model, (ROM) operated by the University of Hawai`i and the National Atmospheric and Oceanic Administration. The ROM provided tides, basin scale circulation, mesoscale variability, and atmospheric forcing into the edges of the EFDC computational domain. This model is the most accurate and sophisticated Hawai'ian Regional Ocean Model presently available, assimilating real-time oceanographic observations, as well as model calibration based upon temperature, current and salinity data collected during 2010 near the simulated OTEC site. The ROM program manager peer-reviewed Makai's implementation of the ROM output into our EFDC model. The supporting oceanographic data was collected for a Naval Facilities Engineering Command / Makai project

  5. Influence of second kind collisions on the electron distribution function in the positive column of low pressure nitrogen discharge

    A numerical solution of the Boltzmann equation for the electron gas in the positive column of a DC discharge in nitrogen is presented. The Boltzmann equation was solved with the inclusion of the second-kind (superelastic) collisions proceeding from the first six excited vibrational levels of molecular nitrogen. The vibrational level population is supposed to follow the Boltzmann distribution for the given vibrational temperature Tsub(v), with a possible deviation of the ground level, which can be overpopulated in the given ratio γ. Apart from the electron distribution functions, which were gained for various values of E/p 0 , Tsub(v) and γ, the values of some production frequencies and kinetic coefficients are presented in form of tables and plots. It is found that the electron distribution (and also the corresponding production rates) only above a certain energy limit depends on Tsub(v) and γ through the normalization constant. (author)

    Full Text Available Uncontrolled fuelwood extraction from conservation forest of Way Kambas National Park (WKNP could threaten the existing forest. This paper studies the way to tackle the forest degradation in WKNP, with less negative impacts to the local people. Study was conducted by analysing existing data and maps of WKNP in terms of forest degradation, forest inventories, current policies, survey on how fuelwood is extracted, observation on fuelwood gatherers, fuelwood demand, and identification of further policy options. Results show that the most significant factors influencing the fuelwood extraction activity in WKNP are land ownership, followed by the distance to forest area, income level, the number of household members and age of household head. In the field, the fuelwood utilization is allowed by WKNP Authority, although it is formally forbidden.It was stated that fuelwood extraction in the area should be less than 2.89 ton/ha/year to maintain its sustainability, based on the mean WNKP forest tree annual increment. The fact shows that fuelwood extraction in WKNP reduces of forest biomass stock (1.06 tons/ha/year and decreases species diversity index (from 3.05 to 2.45, species evenness index (from 1.06 to 0.91 and old-young tree ratio (from 1.29 to 1. Ecosystem quality reduction is mainly caused by destructive techniques in extracting fuelwood such as slashing, scratching cambium, and cutting trees. Therefore, recommended policy includes legalizing fuelwood extraction with restrictions, providing alternative fuelwood and other biomass energy resources outside WKNP, conducting preventive (establishing checkpoints and increasing patrols and pre-emptive (educating and campaigning efforts, collaborating with other stakeholders, and empowering local economy.

    Racism is related to policies preferences and behaviors that adversely affect blacks and appear related to a fear of blacks (e.g., increased policing, death penalty). This study examined whether racism is also related to gun ownership and opposition to gun controls in US whites. The most recent data from the American National Election Study, a large representative US sample, was used to test relationships between racism, gun ownership, and opposition to gun control in US whites. Explanatory variables known to be related to gun ownership and gun control opposition (i.e., age, gender, education, income, conservatism, anti-government sentiment, southern vs. other states, political identification) were entered in logistic regression models, along with measures of racism, and the stereotype of blacks as violent. Outcome variables included; having a gun in the home, opposition to bans on handguns in the home, support for permits to carry concealed handguns. After accounting for all explanatory variables, logistic regressions found that for each 1 point increase in symbolic racism there was a 50% increase in the odds of having a gun at home. After also accounting for having a gun in the home, there was still a 28% increase in support for permits to carry concealed handguns, for each one point increase in symbolic racism. The relationship between symbolic racism and opposition to banning handguns in the home (OR1.27 CI 1.03,1.58) was reduced to non-significant after accounting for having a gun in the home (OR1.17 CI.94,1.46), which likely represents self-interest in retaining property (guns). Symbolic racism was related to having a gun in the home and opposition to gun control policies in US whites. The findings help explain US whites' paradoxical attitudes towards gun ownership and gun control. Such attitudes may adversely influence US gun control policy debates and decisions.

    One central aspect of health literacy is knowledge of patients' rights. Being an important source of information about health and health care, the media may influence health literacy and act as a policy implementer. To investigate whether regional news media coverage in Sweden is linked to (i) the public's awareness and knowledge of a patient's rights policy, the waiting-time guarantee and (ii) the public's attitudes to how the guarantee's time limits are met, that is, implementation success. Three types of data are used. First, a national telephone survey of the public's awareness, knowledge and attitudes; second, media coverage information from digital media monitoring; and third, official waiting-time statistics. Bivariate and multivariate regression analyses are performed with the 21 Swedish county councils/regions as a base. In the county councils/regions, non-awareness ranged from 1 to 15% and knowledge from 47 to 67%. There are relatively large differences between population groups. The amount of regional media coverage shows no significant correlation to the level of awareness and knowledge. There is, however, a significant correlation to both positive and negative attitudes; the latter remains after controlling for actual waiting times. At the national level, the media function as a policy implementer, being the primary source of information. At the regional level, the media are part of the political communication, reporting more extensively in county councils/regions where the population holds negative views towards the achievement in implementing the guarantee. We conclude that Swedish authorities should develop its communication strategies to bridge health literacy inequalities. © 2014 John Wiley & Sons Ltd.

    As an important nutrient source for coastal waters, submarine groundwater discharge (SGD) has long been largely ignored in Daya Bay, China. In this study, we estimate the fluxes of SGD and associated nutrients into this region using a 224Ra mass balance model and assess the contribution/importance of nutrients by SGD, benthic sediments, local rivers, and atmospheric deposition. The results of 224Ra mass balance show that the estimated SGD ranges from (2.76 ± 1.43) × 106 m3/d to (1.03 ± 0.53) × 107 m3/d with an average of (6.32 ± 2.42) × 106 m3/d, about 16 times the total discharge rate of local rivers. The nutrient loading from SGD is estimated to be (1.05-1.99) × 105 mol/d for NO3-N, (4.04-12.16) × 103 mol/d for DIP, and (3.54-11.35) × 105 mol/d for Si. Among these considered nutrient sources, we find that SGD is the primary source for Si and NO3-N, contributing 68% and 42% of all considered sources, respectively. The atmospheric NO3-N flux is comparable to that from SGD. The local rivers are the most important source for DIP, contributing 75% of all considered sources. SGD with high N:P ratio (NO3-N/DIP) of 37.0 delivers not only a large quantity of nutrients, but also changes nutrient structure in coastal water. Based on a DIP budget, primary productivity is evaluated to be 54-73 mg C/m2 d, in which SGD accounts for approximately 30% of total production. This study indicates that SGD is a key source of nutrients to coastal waters and may cause an obvious change of primary production and nutrient structure in Daya Bay.

    Knowledge of the partitioning and sources of mercury are important to understanding the human impact on mercury levels in Lake Superior wildlife. Fluvial fluxes of total mercury (Hg T ) and methylmercury (MeHg) were compared to discharge and partitioning trends in 20 sub-basins having contrasting land uses and geological substrates. The annual tributary yield was correlated with watershed characteristics and scaled up to estimate the basin-wide loading. Tributaries with clay sediments and agricultural land use had the largest daily yields with maxima observed near the peak in water discharge. Roughly 42% of Hg T and 57% of MeHg was delivered in the colloidal phase. Tributary inputs, which are confined to near-shore zones of the lake, may be more important to the food-web than atmospheric sources. The annual basin-wide loading from tributaries was estimated to be 277 kg yr −1 Hg T and 3.4 kg yr −1 MeHg (5.5 and 0.07 mg km −2 d −1 , respectively). - Highlights: ► The highest mercury yields occurred during spring melt except in forested watersheds. ► Roughly half of the mercury yield occurred in the colloidal phase. ► About 277 kg of Hg T and 3.4 kg of MeHg were delivered annually via tributaries. ► Whole-water MeHg loading was roughly equivalent to the estimated atmospheric loading. ► Watersheds with peat, loam or sandy soils deliver more MeHg than those with clays. - Tributary inputs, which are confined to the near-shore zones of Lake Superior, provide more mercury to these sensitive aquatic habitats than direct atmospheric deposition.

    Nickel oxide thin films were deposited on glass substrates as the main gas sensor for H{sub 2} by the DC sputtering technique at various discharge voltages within the range of 1.8–2.5 kV. Their structural, optical and gas sensing properties were investigated by XRD, AFM, SEM, ultraviolet visible spectroscopy and home-made gas sensing measurement units. A diffraction peak in the direction of NiO (200) was observed for the sputtered films, thereby indicating that these films were polycrystalline in nature. The optical band gap of the films decreased from 3.8 to 3.5 eV when the thickness of the films was increased from 83.5 to 164.4 nm in relation to an increase in the sputtering discharge voltage from 1.8 to 2.5 kV, respectively. The gas sensitivity performance of the NiO films that were formed was studied and the electrical responses of the NiO-based sensors toward different H{sub 2} concentrations were also considered. The sensitivity of the gas sensor increased with the working temperature and H{sub 2} gas concentration. The thickness of the NiO thin films was also an important parameter in determining the properties of the NiO films as H{sub 2} sensors. It was shown in this study that NiO films have the capability to detect H{sub 2} concentrations below 3% in wet air, a feature that allows this material to be used directly for the monitoring of the environment.

    Anaerobic digestion (AD) has the potential to contribute to greenhouse gas emissions reductions, improve energy security, increase generation of decentralised renewable electrical and thermal energy, produce low-impact fertiliser and enhance adherence to the principles of proximity as well as self-sufficiency in waste treatment, in energy generation and in resource use. Financial viability is scrutinised investigating optimal logistic pre-conditions such as catchment area or plant size. Given that a breakthrough in deployment does not only depend on technical aspects, the relative importance and magnitude of the necessary incentives is discussed. The influence of policy instruments is studied by devising different incentive scenarios for the United Kingdom. Substantial and predictable rewards for renewable electricity and heat are essential to harness the full potential of AD in addition to the current emphasis on landfill tax. A possible configuration of energy supply companies as a crucial vehicle to bring anaerobic digestion to market is highlighted. (author)

    Sustainable Urban Drainage Systems (SuDS) deliver ecosystems services that can potentially yield multiple benefits to the urban environment. These benefits can be achieved through optimising SUDS' integration with the local environment and water resources, creating so-called Blue Green Solutions (BGS). The BGS paradigm, however, presents several challenges, in particular quantifying the benefits and creating the scientific evidence-base that can persuade high-level decision-makers and stakeholders to implement BGS at large scale. This work presents the development of the easily implemented and tailored-made approach that allows a robust assessment of the BGS co-benefits, and can influence the types of information that are included in policy impact assessments. The Analytic Network Process approach is used to synthesise the available evidence on the co-benefits of the BGS. The approach enables mapping the interactions between individual BGS selection criteria, and creates a platform to assess the synergetic benefits that arise from components interactions. By working with Government departments and other public and private sector stakeholders, this work has produced a simple decision criteria-based network that will enable the co-benefits and trade-offs of BGS to be quantified and integrated into UK policy appraisals.

    Full Text Available The limited availability of water at low prices and the current scheme for specific supply arrangements (SSA/REA, both determined at the political level, explain that the goal of being self-sufficient in terms of forage consumption is currently unattainable in the Canaries. The “PFORCA” Plan aims to counteract this reality and increase their level of self-sufficiency. The financial aid relating to the REA reduces the amount payable for the imported fodder (annual 83,000 t versus local product, which influences the decision making by farmers. According to calculations, performed by reusing the water instead of discharging, Maralfalfa production could be competitive against imports, being financially viable with water prices in a range of 0.20–0.30 €/m3 (prices perfectly acceptable for reclaimed water with low levels of treatment, but fulfilling requirements reuse of Spanish law, RD 1620/2007.

    We develop an agent-based model of utilitarian walking and use the model to explore spatial and socioeconomic factors affecting adult utilitarian walking and how travel costs as well as various educational interventions aimed at changing attitudes can alter the prevalence of walking and income differentials in walking. The model is validated against US national data. We contrast realistic and extreme parameter values in our model and test effects of changing these parameters across various segregation and pricing scenarios while allowing for interactions between travel choice and place and for behavioral feedbacks. Results suggest that in addition to income differences in the perceived cost of time, the concentration of mixed land use (differential density of residences and businesses) are important determinants of income differences in walking (high income walk less), whereas safety from crime and income segregation on their own do not have large influences on income differences in walking. We also show the difficulty in altering walking behaviors for higher income groups who are insensitive to price and how adding to the cost of driving could increase the income differential in walking particularly in the context of segregation by income and land use. We show that strategies to decrease positive attitudes towards driving can interact synergistically with shifting cost structures to favor walking in increasing the percent of walking trips. Agent-based models, with their ability to capture dynamic processes and incorporate empirical data, are powerful tools to explore the influence on health behavior from multiple factors and test policy interventions.

    This study examines the effect of fascicle length change on motor-unit recruitment and discharge rate in the human tibialis anterior (TA) during isometric contractions of various intensities. The torque produced during dorsiflexion and the surface and intramuscular electromyograms (EMGs) from the TA were recorded in eight subjects. The behavior of the same motor unit (n = 59) was compared at two ankle joint angles (+10 and -10 degrees around the ankle neutral position). Muscle fascicle length of the TA was measured noninvasively using ultrasonography recordings. When the ankle angle was moved from 10 degrees plantarflexion to 10 degrees dorsiflexion, the torque produced during maximal voluntary contraction (MVC) was significantly reduced [35.2 +/- 3.3 vs. 44.3 +/- 4.2 (SD) Nm; P Motor units were activated at a lower recruitment threshold for short compared with long muscle fascicle length, either when expressed in absolute values (2.1 +/- 2.5 vs. 3.6 +/- 3.7 Nm; P motor-unit recruitment were observed at a given absolute or relative torque when muscle fascicles were shortened. However, the data indicate that increased rate coding was mainly present at low torque level (recruitment of additional motor units played a dominant role at higher torque level and decreased compliance (10-35% MVC). Taken together, the results suggest that the central command is modulated by the afferent proprioceptive information during submaximal contractions performed at different muscle fascicle lengths.

    In many parts of the world, newly hired science teachers' practices are developing in a complex policy environment. However, little is known about how newly hired science teachers' practices are enacted throughout a cycle of instruction and how these practices can be influenced by macro-, meso-, and micro-policies. Knowing how policies impact practice can result in better policies or better support for certain policies in order to enhance the instruction of newly hired teachers. This comparative study investigated how 12 newly hired science teachers at sites in South Africa (SA) and the United States (US) progressed through an instructional cycle of planning, teaching, and reflection. The qualitative data were analysed through beginning teacher competency frameworks, the cycle of instruction, and institutional theory. Data analysis revealed prevailing areas of practice and connections to levels of policy within the instructional cycle phases. There were some differences between the SA and US teachers and among first-, second-, and third-year teachers. More importantly, this study indicates that newly hired teachers are susceptible to micro-policies and are progressively developing their practice. It also shows the importance of meso-level connectors. It suggests that teacher educators and policy makers must consider how to prepare and support newly hired science teachers to achieve the shared global visions of science teaching.

  6. Discharge patterns of radionuclides and the influence of early diagenesis in a salt-marsh of the Ribble Estuary, NW England

    International Nuclear Information System (INIS)

    Brown, J.E.; Parker, A.; Rae, J.E.

    1997-01-01

    Routine discharges of low level liquid radioactive waste from British Nuclear Fuels plc (BNFL) at Sellafield and Springfield have resulted in enhanced levels of radionuclides in sediments of the Ribble Estuary, NW England, UK. The variations in radionuclide concentrations ( 137 Cs, 230 Th, 232 Th, 238 U, 239,240 Pu and 241 Am) with depth were analysed in order to investigate historical discharge trends. The influence of early diagenesis in terms of radionuclide mobility was established by considering geochemical associations of radionuclides through the depth profile. A core from Longton Marsh was analysed by gamma-spectrometry and alpha-spectrometry. Major/trace metal and total organic carbon determinations were also made. Sequential extractions were employed in order to specify radionuclide phase associations. Distinct subsurface maxima were present for 137 Cs, 241 Am and 239,240 Pu with activities as high as 4500 Bq kg -1 for 137 Cs and 800 Bq kg -1 for 241 Am. Thorium-230 and 238 U exhibited complex activity profiles with depth. 137 Cs was found associated predominantly with the residual phase at all depths. Thorium-230 and 239,240 Pu were mainly associated with the organic and sesquioxide phases with some evidence to suggest that plutonium had undergone a phase redistribution below the sediment surface. Caesium-137, 230 Th and 239,240 Pu were deemed useful in terms of establishing core chronologies. (author)

  7. Decomposition of three volatile organic compounds by nanosecond pulsed corona discharge: Study of by-product formation and influence of high voltage pulse parameters

    Increasing concerns over atmospheric pollution has motivated research into technologies able to remove volatile organic compounds (VOC's) from gas streams. The aim of this paper is to understand the chemical and physical mechanisms implied in the decomposition of VOC's in a filamentary nonthermal plasma discharge. Experiments have been carried out on three pollutants (propane, propene, and isopropyl alcohol) in dry air at atmospheric pressure using a wire to cylinder corona discharge generated by a homemade nanosecond rise time high voltage pulse generator. The resulting plasma efficiently destructs propane, propene, or isopropyl alcohol at a concentration of 500 ppm with low specific input energies (less than 500 J/L), but the poor oxidation rate leads to the formation of numerous by-products (acetone, formaldehyde, formic acid, and methyl nitrate) whose concentration can reach some hundreds of ppm. We also investigated the effect of pulse parameters on VOC removal efficiency. Neither pulse peak value nor rise time (in the range of 4-12 ns) appears to have a significant influence on the VOC decomposition rates. Therefore, we believe that the way the energy is deposited in the plasma does not modify the density of active species (radicals, ions) in the streamers. The production of energetic electrons is not enhanced by the external applied field, and the only effective parameter may be the local field in the streamer head, which is almost the same (around 500 Td) whatever the voltage (above the inception value).

    By applying the concept of the coupled natural and human system (CNH), we compared spatiotemporal changes in livestock (LSK), land cover, and ecosystem production to understand the relative roles that natural and social driving forces have on CNH dynamics on the Mongolia plateau. We used socioeconomic and physical data at prefecture level for Inner Mongolia and Mongolia from 1981 through 2010 to represent changes in net primary productivity (NPP), enhanced vegetation index (EVI), precipitation, annual average temperature, LSK, livestock density (LSKD), land cover change (LCC), gross domestic production (GDP), and population (POP). The ratios such as LSK:NPP, LSKD: EVI, LSKD:albedo, LSK:POP, and LSK:GDP were examined and compared between Inner Mongolia and Mongolia, and structural equation modeling (SEM) was applied to quantify the complex interactions. Substantial differences in LSK, POP, and economic development were found among the biomes and between Inner Mongolia and Mongolia. When various indicators for policy shifts—such as the World Trade Organization (WTO) for China, the Third Campaign to Reclaim Abandoned Agriculture Lands (ATAR-3), and the Grain for Green Program for China (GFG)—were added into our SEM, the results showed significant change in the strength of the above relationships. After China joined the WTO, the relationships in Inner Mongolia between LSKD:LCC and LSKD:NPP were immensely strengthened, whereas relationships in NPP:LCC were weakened. In Mongolia, the ATAR-3 program first appeared to be an insignificant policy, but the Collapse of the Soviet Union enhanced the correlation between LSKD:LCC, weakened the connection of LCC:NPP, and did not affect LSKD:NPP. We conclude that human influences on the Mongolian CNH system exceeded those of the biophysical changes, but that the significance varies in time and per biome, as well as between Inner Mongolia and Mongolia.

    Kenyan national policies for public hospitals dictate that patients are retained on hospital wards until their hospital bills are paid, but this payment process differs for patients with or without access to National Hospital Insurance Fund (NHIF) at diagnosis. Whether these differences impact treatment outcomes has not been described. Our study explores whether childhood cancer treatment outcomes in Kenya are influenced by health-insurance status and hospital retention policies. This study combined retrospective review of medical records with an illustrative case report. We identified children diagnosed with malignancies at a large Kenyan academic hospital between 2007 and 2009, their treatment outcomes, and health-insurance status at diagnosis. Between 2007 and 2009, 222 children were diagnosed with malignancies. Among 180 patients with documented treatment outcome, 54% abandoned treatment, 22% had treatment-related death, 4% progressive/relapsed disease, and 19% event-free survival. Health-insurance status at diagnosis was recorded in 148 children: 23% had NHIF and 77% had no NHIF. For children whose families had NHIF compared with those who did not, the relative risk for treatment abandonment relative to event-free survival was significantly smaller (relative-risk ratio = 0.31, 95% CI = 0.12-0.81, P = 0.016). The case report illustrates difficulties that Kenyan families might face when their child is diagnosed with cancer, has no NHIF, and is retained in hospital. Children with NHIF at diagnosis had significantly lower chance of abandoning treatment and higher chance of survival. Childhood cancer treatment outcomes could be improved by interventions that prevent treatment abandonment and improve access to NHIF. Hospital retention of patients over unpaid medical bills must stop. © 2013 Wiley Periodicals, Inc.

    The responsibility for care and social support in the Netherlands has been decentralized to the municipalities, on the assumption that they are able to organise care and social support more effectively and efficiently. Municipalities are responsible for offering citizens the social support they need. They have policy discretion to decide how and to what extent they encourage and support the use of informal help. This article explored whether the local policy focus on informal or formal help influences the actual take-up of domestic help. Data on 567 physically disabled people who use informal or formal help in the household were linked to local policy data in 167 municipalities. We performed multilevel multinomial regression analyses. Since we expected that local policy will have more influence on people with slight or moderate disabilities, cohabitees and people aged under 75, cross-level interaction terms were included between characteristics of local policy and of individuals. The findings reveal differences between municipalities in their policy on support and differences in the use of formal or informal support between municipalities. We found no relationship between local emphasis on informal help and the use of informal help. Possible explanations: some people have a small social network, people using informal help did not apply for municipality support or even do not know the possibility exists.

    Most probable numbers of Vibrio cholerae and related vibrios were determined in Albufera Lake, Valencia, Spain, and in coastal waters under the influence of the lake discharges over the course of an annual cycle. The influence of temperature, kind of water, and characteristics of the different sampling sites on the numbers of vibrios recovered was evaluated. Maximum recovery of vibrios reached 10(3)/ml in both types of waters analyzed. V. cholerae numbers reached 10(3)/ml in the lake and 10(2) in one of the coastal sites. Frequently during the warm season, all vibrios isolated were identified as V. cholerae. Occasionally, no V. cholerae was recovered. The recovery of vibrios was significantly influenced by the temperature of the water and the type of water analyzed. Most of the V. cholerae isolates were included in Heiberg groups I and II, and nearly 50% of the strains used chitin as sole carbon source. Indole was not produced by 100% of the strains. All strains tested were non-O1 serovars.

    The evaluation of the influences of the examined parameters on the calculation of the dose rate shows that a new concept for determination of the radiation exposure in the surroundings of nuclear facilities is required. A computing formalism based on theoretical considerations determines the effective activity absorbed and, after combination with dose rate factors, the effective dose rate per year. It is of great importance to verify the validity of the still incomplete input data for determination of the dose factors of the age groups 'infants' and 'children' and to prepare new data records.

  2. THE INFLUENCE OF ACCOUNTING SYSTEM AND FISCAL POLICY ON REGIONAL DEVELOPMENT

    Directory of Open Access Journals (Sweden)

    Oana Bogdan

    2014-10-01

    Full Text Available Regional development is a concept that aims at stimulating and diversifying economic activities, stimulating private sector investment and it contributes to reducing unemployment and improving living standards. To achieve these goals accounting and tax policies are necessary to allow private operators to realize taxable income, to create jobs for people and to pay taxes and contributions due to the State budget. The State must reinvest a part of the resources collected to the community in order to improve infrastructure, education and health, thus contributing to regional development. Changes in tax law and accounting adopted in Romania during 2009-2014 are regarded as tax breaks for companies created to ensure economic growth, dynamic and sustainable through efficient use of regional and local potential. In this paper we analyze the influence of the accounting and fiscal system on the regional development given that these measures do not always achieve their objectives established companies having benefit from the application of various tax measures. The paper will present the main changes of the tax and accounting systems and their impact on the regional development in Romania and the consequences resulting in implementing these measures.

  3. An analysis of Renewable Portfolio Standard policy formulation and its influence on state level energy prices

    Science.gov (United States)

    McCollester, Peter Colin

    understand the relationship between RPS and energy markets. This study utilizes state level panel data from 2000 to 2011 to examine this relationship. The model controls for several factors including the existence of state level RPS, the amount of electricity generation from renewable and non-renewable sources, fuel price mix, and other macroeconomic and demographic indicators. The study compares and contrasts several regressions to illuminate important relationships between RPS design and residential energy prices. The findings of this study have the potential to have far reaching implications for the future of RPS design, and RPS policy. This paper finds that RPS and more specifically the way a RPS is formulated is related to increased energy prices. Retail energy prices are particularly strongly related to variables having to do with compliance with a specific RPS, while Industrial energy prices are more strongly related to the magnitude of RPS goals. Both of these findings are important and they accentuate the fact that different energy markets are influenced by different drivers.

    1992-01-01

    The essential differences between high-frequency capacative discharges at intermediate and low pressures are considered. A theory is developed for the negative emission region and the Faraday dark space in a γ discharge. It is based on the kinetic equation for electrons in the highly nonuniform field of an electrode sheath, which is solved in the forward-backward approximation. If a uniform positive column is formed in the middle of the gap of a γ discharge of average pressure which is not too short, then at low pressures the hf plasma acts as the equivalent of the negative emission or Faraday space of a glow discharge with a typical weak field and low electron temperature. A region of reversed average field also appears, which is characteristic of a glow discharge. The question of the normal current density effect in an α discharge is discussed. This effect is observed at average pressures. At low pressures the effect disappears, and even weak current covers the entire electrode; the pressures at which this occurs and the reasons for it are demonstrated. The nature of the α-γ transition, which takes place discontinuously at average pressures but continuously at lower pressures, is discussed. The reason for this behavior is discussed and the pressure at which the discontinuous mechanism changes into continuous is estimated

    Although emotions and ideology are important factors guiding policy support in conflict, their interactive influence remains unclear. Based on prior findings that ideological leftists' beliefs are more susceptible to change than rightists' beliefs, we tested a somewhat counterintuitive extension that leftists would be more susceptible to influence by their emotional reactions than rightists. In three laboratory studies, inducing positive and negative emotions affected Jewish-Israeli leftists', but not rightists', support for conciliatory policies toward an adversarial (Studies 1 and 3) and a non-adversarial (Study 2) outgroup. Three additional field studies showed that positive and negative emotions were related to leftists', but not rightists', policy support in positive as well as highly negative conflict-related contexts, among both Jewish (Studies 4 and 5) and Palestinian (Study 6) citizens of Israel. Across different conflicts, emotions, conflict-related contexts, and even populations, leftists' policy support changed in accordance with emotional reactions more than rightists' policy support. © 2014 by the Society for Personality and Social Psychology, Inc.

    The Siberian Chemical Combine (SCC) is located in Seversk (formerly known as Tomsk-7) in the Tomsk Region of the Russian Federation. The main contribution of radionuclides in the SCC process water discharged into the Tom River was from the single-pass reactors, now removed from service (the last SCC reactor was shutdown on June 5, 2008). The data on the concentrations of 90 Sr, 137 Cs, 239,240 Pu and other artificial radionuclides in water, bottom sediments and flood-plain soils of the Tom and Ob rivers from Tomsk to the confluence of the rivers, are presented and discussed. The results of measurements carried out after shutdown of the last SCC single-pass reactor indicated no radiologically significant consequences of SCC activities for the studied water environment compartments. Contemporary activity concentrations of long-lived artificial radionuclides 3 H, 90 Sr, 137 Cs and 239,240 Pu in river water were below the intervention levels established by current regulations of the Russian Federation for these radionuclides. The results of 3 H analysis in water from the Tom and Samuska rivers demonstrated no inflow of contaminated formation water to surface water from the sites where liquid radioactive wastes of the SCC were injected below the surface. However, the density of flood-plain soil contamination by long-lived 137 Cs in the area influenced by SCC liquid discharges was higher than regional technogenic background. There were local flood-plain areas contaminated not only by 137 Cs, but also other gamma-emitters, such as 60 Co and 152 Eu.

    Controversy exists regarding whether the decision to pursue a do-not-resuscitate (DNR) order should be grounded in an ethic of patient autonomy or in the obligation to act in the patient's best interest (beneficence). To explore how physicians' approaches to DNR decision making at the end of life are shaped by institutional cultures and policies surrounding patient autonomy. We performed semistructured in-depth qualitative interviews of 58 internal medicine physicians from 4 academic medical centers (3 in the United States and 1 in the United Kingdom) by years of experience and medical subspecialty from March 7, 2013, through January 8, 2014. Hospitals were selected based on expected differences in hospital culture and variations in hospital policies regarding prioritization of autonomy vs best interest. This study identified the key influences of institutional culture and policies on physicians' attitudes toward patient autonomy in DNR decision making at the end of life. A hospital's prioritization of autonomy vs best interest as reflected in institutional culture and policy appeared to influence the way that physician trainees conceptualized patient autonomy. This finding may have influenced the degree of choice and recommendations physician trainees were willing to offer regarding DNR decision making. Trainees at hospitals where policies and culture prioritized autonomy-focused approaches appeared to have an unreflective deference to autonomy and felt compelled to offer the choice of resuscitation neutrally in all situations regardless of whether they believed resuscitation to be clinically appropriate. In contrast, trainees at hospitals where policies and culture prioritized best-interest-focused approaches appeared to be more comfortable recommending against resuscitation in situations where survival was unlikely. Experienced physicians at all sites similarly did not exclusively allow their actions to be defined by policies and institutional culture and were

    The contribution of aviation to global carbon dioxide (CO 2 ) emissions is projected to triple by 2050. As nations strive to meet CO 2 reduction targets, policy interventions to manage the growth of emissions arising from air travel are likely. Here, we investigate the potential influence of aviation emissions reduction policies on the business travel patterns of individual corporations. Using travel data from six UK-based companies, we find that increased ticket prices can deliver substantial emissions cuts, particularly on premium class flights, and may provide strong financial incentives to seek modal and/or technological alternatives to flying. We also find that corporations from different business sectors vary in their responsiveness to a range of policy options. Finally, we examine questionnaire data to determine whether companies more broadly are going beyond compliance to mitigate their environmental impact by managing travel-related emissions voluntarily. Although many corporations are measuring and reporting emissions, only a limited number are willing to implement in-house reduction policies prior to regulation. - Research highlights: →Ticket price rises can deliver substantial emissions cuts, particularly on premium class flights. → Corporations from different business sectors vary in their responsiveness to policy options. → Many companies measure emissions but few will apply in-house reduction policies before regulation.

    There is a scarcity of empirical data on the influence of initiatives supporting evidence-informed health system policy-making (EIHSP), such as the knowledge translation platforms (KTPs) operating in Africa. To assess whether and how two KTPs housed in government-affiliated institutions in Cameroon and Uganda have influenced: (1) health system policy-making processes and decisions aiming at supporting achievement of the health millennium development goals (MDGs); and (2) the general climate for EIHSP. We conducted an embedded comparative case study of four policy processes in which Evidence Informed Policy Network (EVIPNet) Cameroon and Regional East African Community Health Policy Initiative (REACH-PI) Uganda were involved between 2009 and 2011. We combined a documentary review and semi structured interviews of 54 stakeholders. A framework-guided thematic analysis, inspired by scholarship in health policy analysis and knowledge utilization was used. EVIPNet Cameroon and REACH-PI Uganda have had direct influence on health system policy decisions. The coproduction of evidence briefs combined with tacit knowledge gathered during inclusive evidence-informed stakeholder dialogues helped to reframe health system problems, unveil sources of conflicts, open grounds for consensus and align viable and affordable options for achieving the health MDGs thus leading to decisions. New policy issue networks have emerged. The KTPs indirectly influenced health policy processes by changing how interests interact with one another and by introducing safe-harbour deliberations and intersected with contextual ideational factors by improving access to policy-relevant evidence. KTPs were perceived as change agents with positive impact on the understanding, acceptance and adoption of EIHSP because of their complementary work in relation to capacity building, rapid evidence syntheses and clearinghouse of policy-relevant evidence. This embedded case study illustrates how two KTPs influenced

    Montevideo Bay is located in the middle zone of the Rio de la Plata, and since the foundation of the city, several key economic and environmental policies affected the industry, and thus, metal inputs into this ecosystem. The aim of this study is to evaluate the sedimentary geochemical record of Montevideo Bay, in order to determine the historical inputs of anthropogenic metals to the system. In addition, environmental and economic policies of the country were taken into account to infer the relationship between them and the historic metal input. Concentrations of aluminum, chromium, copper, lead, scandium and zinc were analyzed and the EF and SPI indices were calculated. The analysis showed that since Montevideo foundation, metal concentrations increased in accordance with industry development, and the indices as well as the metal concentration represent a reliable footprint of the history of different economic and environmental policies influencing historical industrial activities.

    Almansoori, Ali

    2014-01-01

    South Korea is the fifth top oil importer worldwide with 64% of its oil coming from OPEC member countries. Over the last 30 years, South Korea accounted for a rapid increase in energy use. This in turn led South Korea to be totally dependent on oil imports. Due to this increase, South Korea has been experiencing drastic changes in its energy system which could potentially impact its dependence on OPEC oil import. External and internal factors have forced South Korea to change its energy strategy and targets. These targets would be achieved by reducing its energy intensity and utilizing electricity and renewable energies in order to reduce its dependence on oil consumption. “Low Carbon, Green Growth” is one policy along with many other energy policies developed by South Korea for reducing greenhouse gases, thus this policy is receiving a remarkable attention today. These national policies along with other international ones are needed to mitigate greenhouse gas emissions and promote other green initiatives. This study puts emphasis on these policies as well as uses them to predict the future energy profile of South Korea and how these policies will impact on oil imports from OPEC member countries. - Highlights: • Analyze energy policy of South Korea and its energy profiles. • Study the factors that affect South Korea to change its energy strategy and targets. • Analyze the implications of South Korean energy policy on oil imports from OPEC. • South Korea will continue importing oil from OPEC countries for the next decade

    Massey, Andrew

    1988-01-01

    The role of technical experts, especially scientists and engineers, in the development of Britain's civil nuclear energy policy is analysed. It is proposed that civil initiatives came from the integration of technical professions within the bureaucracy of government and quasi-governmental organisations involved in the formulation and implementation of policy. Organisational logic and professional motivation encouraged policies which would lead to occupational autonomy. The first three chapters develop the concept of technical professionalism, Chapters 4-7 then focus on the technocrat's role in providing a spur from their positions within the policy community's bureaucracies that drives top-level policy decisions. These functions are examined in more detail using two case studies, the first concerned with the evolution of British Nuclear Fuels Ltd., the second with the Inquiry (in 1977) into the proposal by BNFL to extend its Windscale site (now known as Sellafield) to build the Thermal Oxide Reprocessing Plant.

    Though the problems translating or applying research in policy-making are legion, solutions are rare. As developing countries increase their capacities to develop effective local solutions to their health problems, they confront the research/policy dilemma. Yet few descriptive studies of research-policy links can be found from developing countries, and the relevance of European and North American models and data is questionable. We report the results of a descriptive study from Mexico of the relationship between health research and policy in four vertical programmes (AIDS, cholera, family planning, immunization). We interviewed 67 researchers and policy-makers from different institutions and levels of responsibility. We analyzed interviewee responses looking for factors that promoted or impeded exchanges between researchers and policy-makers. These were, in turn, divided into emphases on content, actors, process, and context. Many of the promoting factors resembled findings from studies in industrialized countries. Some important differences across the four programmes, which also distinguish them from industrialized country programmes, included extent of reliance on formal communication channels, role of the mass media in building social consensus or creating discord, levels of social consensus, role of foreign donors, and extent of support for biomedical versus social research. We recommend various ways to increase the impact of research on health policy-making in Mexico. Some of the largest challenges include the fact that researchers are but one of many interest groups, and research but one input among many equally legitimate elements to be considered by policy-makers. Another important challenge in Mexico is the relatively small role played by the public in policy-making. Further democratic changes in Mexico may be the most important incentive to increase the use of research in policy-making.

    For the past decade, Thailand pursued a strategy of promoting biofuel crop production, including sugarcane, to meet the ever increasing energy demand and to increase the income of farmers. This study analyzed the influence of policy instruments implemented to promote the sugarcane cultivation, farm household socioeconomic levels, biophysical, and institutional factors driving the conversion of rice fields into sugarcane farms. Primary information was collected from 230 farm households through a structured questionnaire. Relevant policy documents published by the responsible government agencies were the main sources of secondary information collected for policy analysis. The analyses revealed that farmers in the study area converted 25-75% of their rice fields into sugarcane farms as a result of implementation of policy instruments that made sugarcane financially far more attractive than rice. The results of the regression analysis showed that eight variables were found significant and positively influenced the conversion of rice fields into sugarcane farms. These were access to extension services, information, sugarcane loading stations, and ground water for irrigation, and duration of experience in sugarcane farming as well as household head's age and education. Irrespective of landholding size, the majority of farmers were not concerned about food security. In view of the finding, if feasible, in the form of additional price supports and commercial cane sugar index-based pricing strategies to promote sugarcane production should benefit all concerned farmers. Likewise, attention should be paid to deliver essential extension and marketing services in an effective way, particularly to those farmers who are not receiving such services.

    During times of crisis, communities and regions rely heavily on critical infrastructure systems to support their emergency management response and recovery activities. Therefore, the resilience of critical infrastructure systems to crises is a pivotal factor to a community’s overall resilience. Critical infrastructure resilience can be influenced by many factors, including State policies – which are not always uniform in their structure or application across the United States – were identified by the U.S. Department of Homeland Security as an area of particular interest with respect to their the influence on the resilience of critical infrastructure systems. This study focuses on developing an analytical methodology to assess links between policy and resilience, and applies that methodology to critical infrastructure in the Transportation Systems Sector. Specifically, this study seeks to identify potentially influential linkages between State transportation capital funding policies and the resilience of bridges located on roadways that are under the management of public agencies. This study yielded notable methodological outcomes, including the general capability of the analytical methodology to yield – in the case of some States – significant results connecting State policies with critical infrastructure resilience, with the suggestion that further refinement of the methodology may be beneficial.

    Hypertension is more common in eldery female that triggered by diet and lifestyle changes. Bananas were not only useful for the food, but also for hypertension therapy and preserving life. Administration of bananas decreased blood pressure in hypertensive patients. This study aims to identify of factors that influenced by the administration of banana (Musa paradisiaca) on elderly female hypertensive patient. Twenty of eldery female patient were divided into 2 respondents group: control (11 patients) and treatment (9 patients). The treatment groups received banana twice a day during 2 weeks, but the control group didn’t. Here, we showed the administration of banana significantly decreased blood pressure on elderly female hypertensive patient (p = 0.00) in both systole and diastole. There was a significant decrease in sodium levels (p = 0.037) in the blood, but potassium levels remained the same. Erythrocyte sedimentation level (p = 0.136) and trombocyte count (p = 0.176) in treatment group, were not affected by banana administration. Taken together, banana administration on elderly female hypertensive patient decreased the blood pressure significantly, greatly affected by the natrium dischargement from the blood. Thus, our findings contribute to preliminary comprehension of banana effect on hypertension reduction.

    The influence of N2 partial pressure on structural, mechanical and wetting properties of multilayered TiN/ZrN thin films deposited on silicon substrates by vacuum arc discharge of (N2 + Ar) gas mixtures is investigated. X-ray diffraction (XRD) results show that the average texturing coefficient of (1 1 1) orientation and the grain size of both TiN and ZrN individual layers increase with increasing the N2 partial pressure. The Rutherford back scattering (RBS) measurements and analysis reveal that incorporation of the nitrogen in the film increases with increasing the N2 partial pressure and both TiN and ZrN individual layers have a nitrogen over-stoichiometry for N2 partial pressure ⩾50%. The change in the film micro-hardness is correlated to the changes in crystallographic texture, grain size, stoichiometry and the residual stress in the film as a function of the N2 partial pressure. In particular, stoichiometry of ZrN and TiN individual is found to play the vital role in determining the multilayer hardness. The multilayer film deposited at N2 partial pressure of 25% has the best stoichiometric ratio of both TiN and ZrN layers and the highest micro-hardness of about 32 GPa. In addition, water contact angle (WCA) measurements and analysis show a decrease in the work of adhesion on increasing the N2 partial pressure.

    The results of the influence of nitridation temperature and time on the surface hardness of AISI 1010 low carbon steels nitrided by means of plasma glow discharge technique are presented in this paper. The results are the changing of surface hardiness, the changing of surface microstructure and the penetration profile depth. The experiment has been carried out at the temperature 400 o C, 450 o C, 500 o C, 550 o C, 570 o C and 600 o C, whereas the time is 5 minutes, 15 minutes, 40 minutes, 90 minutes and 180 minutes. All the experiments have been carried out at the optimum plasma density condition. The optimum plasma density condition is achieved at the pressure of p = 0.2 torr, when thr gas flow of nitrogen is 0.6 liter/minute and the distance of electrode plate is 4.5 cm. It was found that the optimum hardness of the surface was achieved at the temperature of 570 o C and the time of nitridation was 90 minutes, i.e. 190 KHN

    This work extends our previous experimental studies of the chemistry of Titan's atmosphere by atmospheric glow discharge. The Titan's atmosphere seems to be similarly to early Earth atmospheric composition. The exploration of Titan atmosphere was initiated by the exciting results of the Cassini-Huygens mission and obtained results increased the interest about prebiotic atmospheres. Present work is devoted to the role of CO 2 in the prebiotic atmosphere chemistry. Most of the laboratory studies of such atmosphere were focused on the chemistry of N 2  + CH 4 mixtures. The present work is devoted to the study of the oxygenated volatile species in prebiotic atmosphere, specifically CO 2 reactivity. CO 2 was introduced to the standard N 2  + CH 4 mixture at different mixing ratio up to 5 % CH 4 and 3 % CO 2 . The reaction products were characterized by FTIR spectroscopy. This work shows that CO 2 modifies the composition of the gas phase with the detection of oxygenated compounds: CO and others oxides. There is a strong influence of CO 2 on increasing concentration other products as cyanide (HCN) and ammonia (NH 3 ).

    Convective redistribution of ozone and its precursors between the boundary layer (BL) and the free troposphere (FT) influences photochemistry, in particular in the middle and upper troposphere (UT). We present a case study of convective transport during the GABRIEL campaign over the tropical rain forest in Suriname in October 2005. During one measurement flight the inflow and outflow regions of a cumulonimbus cloud (Cb) have been characterized. We identified a distinct layer between 9 and 11 km altitude with enhanced mixing ratios of CO, O3, HOx, acetone and acetonitrile. The elevated O3 contradicts the expectation that convective transport brings low-ozone air from the boundary layer to the outflow region. Entrainment of ozone-rich air is estimated to account for 62% (range: 33-91%) of the observed O3. Ozone is enhanced by only 5-6% by photochemical production in the outflow due to enhanced NO from lightning, based on model calculations using observations including the first reported HOx measurements over the tropical rainforest. The "excess" ozone in the outflow is most probably due to direct production by corona discharge associated with lightning. We deduce a production rate of 5.12 × 1028 molecules O3 flash-1 (range: 9.89 × 1026-9.82 × 1028 molecules O3 flash-1), which is at the upper limit of the range reported previously.

    2017-03-01

    The efficacy of low- and middle-income countries’ (LMIC) national drug policies in managing antiretroviral (ARV) pharmaceutical prices is not well understood. Though ARV drug prices have been declining in LMIC over the past decade, little research has been done on the role of their national drug policies. This study aims to (i) analyse global ARV prices from 2004 to 2013 and (ii) examine the relationship of national drug policies to ARV prices. Analysis of ARV drug prices utilized data from the Global Price Reporting Mechanism from the World Health Organization (WHO). Ten of the most common ARV drugs (first-line and second-line) were selected. National drug policies were also assessed for 12 countries in the South African Development Community (SADC), which self-reported their policies through WHO surveys. The best predictor of ARV drug price was generic status—the generic versions of 8 out of 10 ARV drugs were priced lower than branded versions. However, other factors such as transaction volume, HIV prevalence, national drug policies and PEPFAR/CHAI involvement were either not associated with ARV drug price or were not consistent predictors of price across different ARV drugs. In the context of emerging international trade agreements, which aim to strengthen patent protections internationally and potentially delay the sale of generic drugs in LMIC, this study shines a spotlight on the importance of generic drugs in controlling ARV prices. Further research is needed to understand the impact of national drug policies on ARV prices.

Many stakeholders from the publicand private sectors are investing a lot of effort to identify consumer behaviour for futureimprovements in development of green products and effective strategies, which couldaccelerate the transition to sustainable future. This paper presents the effects of electricvehicle promotional policies and customer preferences about alternative fuel vehicles.This study has shown that the electric vehicle promotional policies adopted in Sloveniahave been unsuccessful, as the share of first-time registered electric vehicles in 2013 wasbelow 1%. For different segments of people whose opinions about low emission vehiclesdiffer, different measures must be adopted. When designing promotional policies focusmust be on the most relevant factors such as the total vehicle price and fuel economy.

Also, the article defines and characterizes three main phases of the government debt policy: pre-stabilization, stabilization and post-stabilization. The author analyzes main aspects of the relationship between dept policy and monetary one. Methodology. The study is based on the works of domestic and foreign scientists engaged in research of the given problem. Theoretical concepts are supported by statistical data of key macroeconomic indicators of Ukraine’s economy. Results of the survey showed that the relationship between the debt policy and measures of macro-regulation during the transformation has the stable and permanent nature, and the use of certain instruments of government debt management is exclusively possible for a definite direction of macro policy on the one hand, and they are the elements in the system of measures for its implementation on the other hand. In the pre-stabilization phase of transformation the debt policy synthesizes the expansive solutions of monetary and fiscal authorities, and a direct link between them mediate the expansion of demand in the public sector and the preservation of soft budget constraints for micro-units; in the stabilization phase the relationship between fiscal, monetary and debt policy becomes more indirect, but are direct in that part of the borrowing purposes, subordinated to the creation of macro-stabilization mechanism of transformation; in the poststabilization period the role of indirect interconnection between the debt measures and fiscal and monetary decisions increases, but the lack of a deep micro-restructuring and deep systemic and structural reforms cause the deterioration in the macro-economic state of the system, due to which the vector of government borrowing again gravitates toward the field

    It appears that the continuous efforts to add up of tobacco control policies in the context of a nationwide anti-tobacco mass media campaign that includes the Quitline number is the most effective approach to maintaining the upward trend in smoking cessation intentions. Based on the Korean experience, Quitline data may be useful for measuring the impact of tobacco control policies and campaigns in Asian Pacific countries.

    In this paper, a thin transparent titania (TiO{sub 2}) film was coated on the surface of flexible poly(ethylene terephthalate) (PET) film using the sol–gel method. The surface properties of the obtained TiO{sub 2}/PET film were further improved by RF glow discharge oxygen plasma as a function of exposure time and discharge power. The changes in hydrophilicity of TiO{sub 2}/PET films were analyzed by contact angle measurements and surface energy. The influence of plasma on the surface of the TiO{sub 2}/PET films was analyzed by atomic force microscopy (AFM) as well as the change in chemical state and composition that were investigated by X-ray photo electron spectroscopy (XPS). The cytotoxicity of the TiO{sub 2}/PET films was analyzed using human osteoblast cells and the bacterial eradication behaviors of TiO{sub 2}/PET films were also evaluated against Staphylococcus bacteria. It was found that the surface roughness and incorporation of oxygen containing polar functional groups of the plasma treated TiO{sub 2}/PET films increased substantially as compared to the untreated one. Moreover the increased concentration of Ti{sup 3+} on the surface of plasma treated TiO{sub 2}/PET films was due to the transformation of chemical states (Ti{sup 4+} → Ti{sup 3+}). These morphological and chemical changes are responsible for enhanced hydrophilicity of the TiO{sub 2}/PET films. Furthermore, the plasma treated TiO{sub 2}/PET film exhibited no citotoxicity against osteoblast cells and antibacterial activity against Staphylococcus bacteria which can find application in manufacturing of biomedical devices. - Graphical abstract: Mechanism of plasma treatment on the surface of TiO{sub 2}/PET films. - Highlights: • Investigated the surface properties of TiO{sub 2}/PET films modified by O{sub 2} plasma • Studied the effect of operating parameters on surface properties of TiO{sub 2}/PET films • Mechanism of the plasma treatment on TiO{sub 2}/PET was clearly investigated.

    The movement of skilled physicians from the public to the private sector is a key constraint to achieving universal health coverage and is currently affecting health systems worldwide. This systematic review aims to assess factors influencing physicians' choice of workplace, and policy interventions for retaining physicians in the public sector. Five literature databases were searched. Studies were included in the review if they focused on at least one of the following criteria: (i) incentives or motivators for retaining physicians in the public sector, (ii) pull factors that encouraged physicians to move to the private sector, (iii) push factors that forced physicians to leave the public sector, (iv) policy interventions or case studies that addressed physician retention in the public sector, and (v) qualitative reviews of policy interventions that were implemented in different health system settings. Nineteen articles met the inclusion criteria. Six major themes that affected physicians' choice of workplace were identified including: financial incentives, career development, infrastructure and staffing, professional work environment, workload and autonomy. The majority of the studies suggested that the use of financial incentives was a motivator in retaining physicians in the public sector. The review also identified policy interventions including: regulatory controls, incentives and management reforms. Regulatory controls and incentives were the two most frequently reported policy interventions. While factors affecting physicians' choice of workplace are country specific, financial incentives and professional development are core factors. Other factors are highly influenced by context, and thus, it would be useful for future cross-country research to use standardized data collection tools, allowing comparison of contextual factors as well as the examination of how context affects physician retention in the public sector.

  1. Interest Groups' Influence over Drug Pricing Policy Reform in South Korea

    2005-01-01

    In 1999, the Korean government made a drug pricing policy reform to improve the efficiency and transparency of the drug distribution system. Yet, its policy formation process was far from being rational. Facing harsh resistance from various interest groups, the government changed its details into something different from what was initially investigated and planned. So far, little evidence supports any improvement in Korea's drug distribution system. Instead, the new drug pricing policy has deteriorated Korea's national health insurance budget, indicating a heavier economic burden for the general public. From Korea's experience, we may draw some lessons for the future development of a better health care system. As a society becomes more pluralistic, the government should come out of authoritarianism and thoroughly prepare in advance for resistance to reform, by making greater efforts to persuade strong interest groups while informing the general public of potential benefits of the reform. Additionally, facing developing civic groups, the government should listen but not rely too much on them at the final stage of the policy formation. Many of the civic groups lack expertise to evaluate the details of policy and tend to act in a somewhat emotional way. PMID:15988802

    Gender inequalities in health have been widely described, but few studies have examined the upstream sources of these inequalities in health. The objectives of this review are 1) to identify empirical papers that assessed the effect of gender equality policies on gender inequalities in health or on women's health by using between-country (or administrative units within a country) comparisons and 2) to provide an example of published evidence on the effects of a specific policy (parental leave) on women's health. We conducted a literature search covering the period from 1970 to 2012, using several bibliographical databases. We assessed 1,238 abstracts and selected 19 papers that considered gender equality policies, compared several countries or different states in 1 country, and analyzed at least 1 health outcome among women or compared between genders. To illustrate specific policy effects, we also selected articles that assessed associations between parental leave and women's health. Our review partially supports the hypothesis that Nordic social democratic welfare regimes and dual-earner family models best promote women's health. Meanwhile, enforcement of reproductive policies, mainly studied across US states, is associated with better mental health outcomes, although less with other outcomes. Longer paid maternity leave was also generally associated with better mental health and longer duration of breastfeeding.

  3. Policy Influence on Consumers’ Evolution into Prosumers—Empirical Findings from an Exploratory Survey in Europe

    Full Text Available The energy sector is in transition to a flexible and sustainable energy system based on renewable energy sources. This complex transition is affecting multiple levels in the sociotechnical system. One driver of the transition is climate change that enforces the policy push from the macro level to change the way energy is produced, delivered, and used. As part of the energy system evolution, the role of the end user in the energy sector is undergoing profound changes, and consumers are increasingly being empowered to participate actively in the production and use of energy. This article investigates how policies might affect consumers’ interests in becoming prosumers of energy. We explore consumers’ attitudes toward using renewable energy technologies (RET by means of an empirical consumer survey that was conducted in five European countries. The partial least squares structural equation modeling (PLS-SEM method was utilized to analyze the survey results. Our findings suggest that both economic and non-economic policies affect consumer attitudes toward using renewable energy technologies. We conclude that policies have different effects on consumers and prosumers, who have already made the decision to adopt renewable energy solutions. Based on the findings, we propose a set of policy and managerial implications.

    Hilton, Shona

    2015-01-01

    Aims: To explore how policy actors attempted to deliberately frame public debate around alcohol minimum unit pricing (MUP) in the UK by comparing and contrasting their constructions of the policy in public (newspapers), semi-public (evidence submissions) and private (interviews). Methods: Content analysis was conducted on articles published in ten national newspapers between 1 January 2005 and 30 June 2012. Newsprint data were contrasted with alcohol policy documents, evidence submissions to the Scottish Parliament's Health and Sport Committee and 36 confidential interviews with policy stakeholders (academics, advocates, industry representatives, politicians and civil servants). Findings: A range of policy actors exerted influence both directly (through Parliamentary institutions and political representatives) and indirectly through the mass media. Policy actors were acutely aware of mass media's importance in shaping public opinion and used it tactically to influence policy. They often framed messages in subtly different ways, depending on target audiences. In general, newspapers presented the policy debate in a “balanced” way, but this arguably over-represented hostile perspective and suggested greater disagreement around the evidence base than is the case. Conclusions: The roles of policy actors vary between public and policy spheres, and how messages are communicated in policy debates depends on perceived strategic advantage. PMID:26045639

    Till this time known methods of the excitation of the discharge between electrodes are using either secondary or thermo emission of electrons by the cathode. Usually we speak about the self-maintained discharge. Lifetime of the cathode, that is shortened by the emission, limits in principle, the lifetime of the whole discharge tube. The discharge can, according to the present state of the art, be induced also by the inductive way. Arrangement for excitation of such discharge is rather expensive. The construction of the inductive excited discharge tube is considerably influenced by the necessity of the limitation of the losses in excitation magnetic circuits. Especially length of the discharge and pressure of the working gas are limited by the economic standpoints. Function of the discharge is always connected with unwanted electromagnetic radiation, whose restraint is expensive and represents limiting factor for arrangement of the discharge tube (Authors)

    The contribution of aviation to global carbon dioxide (CO{sub 2}) emissions is projected to triple by 2050. As nations strive to meet CO{sub 2} reduction targets, policy interventions to manage the growth of emissions arising from air travel are likely. Here, we investigate the potential influence of aviation emissions reduction policies on the business travel patterns of individual corporations. Using travel data from six UK-based companies, we find that increased ticket prices can deliver substantial emissions cuts, particularly on premium class flights, and may provide strong financial incentives to seek modal and/or technological alternatives to flying. We also find that corporations from different business sectors vary in their responsiveness to a range of policy options. Finally, we examine questionnaire data to determine whether companies more broadly are going beyond compliance to mitigate their environmental impact by managing travel-related emissions voluntarily. Although many corporations are measuring and reporting emissions, only a limited number are willing to implement in-house reduction policies prior to regulation. (author)

    Montevideo Bay is located in the middle zone of the Rio de la Plata, and since the foundation of the city, several key economic and environmental policies affected the industry, and thus, metal inputs into this ecosystem. The aim of this study is to evaluate the sedimentary geochemical record of Montevideo Bay, in order to determine the historical inputs of anthropogenic metals to the system. In addition, environmental and economic policies of the country were taken into account to infer the relationship between them and the historic metal input. Concentrations of aluminum, chromium, copper, lead, scandium and zinc were analyzed and the EF and SPI indices were calculated. The analysis showed that since Montevideo foundation, metal concentrations increased in accordance with industry development, and the indices as well as the metal concentration represent a reliable footprint of the history of different economic and environmental policies influencing historical industrial activities. - Highlights: • Trace metal record of a sediment core of Montevideo Bay/harbor was studied. • The historic inputs of metals in the area were inferred. • System degradation evolved from anthropogenic impacts. • A relationship between pollution and environmental/economic policies was discussed.

  11. Local variability in long-term care services: local autonomy, exogenous influences and policy spillovers.

    2015-03-01

    In many countries, public responsibility over the funding and provision of long-term care services is held at the local level. In such systems, long-term care provision is often characterised by significant local variability. Using a panel dataset of local authorities over the period 2002-2012, the paper investigates the underlying causes of variation in gross social care expenditure for older people in England. The analysis distinguishes between factors outside the direct control of policy makers, local preferences and local policy spillovers. The results indicate that local demand and supply factors, and to a much lesser extent local political preferences and spatial policy spillovers, explain a large majority of the observed variation in expenditure.

  12. Influence of the configuration of the magnetic filter field on the discharge structure in the RF driven negative ion source prototype for fusion

    The study provides results for the influence of the filter field topology on the plasma parameters in the RF prototype negative ion source for ITER NBI. A previously developed 2D fluid plasma model of the prototype source was extended towards accounting for the particles and energy losses along the magnetic field lines and the presence of a magnetic field in the driver which is the case at the BATMAN and ELISE test-beds. The effect of the magnetic field in the driver is shown for the magnetic field configuration of the prototype source (i.e. a magnetic field produced by an external magnet frame) by comparison of plasma parameters without and with the magnetic field in the driver and for different axial positions of the filter. Since the ELISE-like magnetic field (i.e. a magnetic field produced by a current flowing through the plasma grid) is a new feature planned to be installed at the BATMAN test-bed, its effect on the discharge structure was studied for different strengths of the magnetic field. The obtained results show for both configurations of the magnetic filter the same main features in the patterns of the plasma parameters in the expansion chamber: a strong axial drop of the electron temperature and the formation of a groove accompanied with accumulation of electrons in front of the plasma grid. The presence of a magnetic field in the driver has a local impact on the plasma parameters: the formation of a second groove of the electron temperature in the case of BATMAN (due to the reversed direction of the filter field in the driver) and a strong asymmetry of the electron density. Accounting for the additional losses in the third dimension suppresses the drifts across the magnetic field and, thus, the variations of the electron density in the expansion chamber are less pronounced.

    Convective redistribution of ozone and its precursors between the boundary layer (BL) and the free troposphere (FT) influences photochemistry, in particular that of the middle and upper troposphere (UT). We present a case study of convective transport during the GABRIEL campaign over the tropical rain forest in Suriname in October 2005. During a measurement flight on 12 October the inflow and outflow regions of a cumulonimbus cloud (Cb) have been characterized, providing evidence of convective transport. We identified a distinct layer between 9 and 11 km altitude with enhanced mixing ratios of CO, O3, HOx, acetone and acetonitrile. The elevated O3 contradicts the expectation that convective transport brings low ozone air from the boundary layer to the outflow region. The enhanced mixing ratio of ozone in the outflow was mainly of dynamical origin. Entrainment of ozone rich air at the outflow level into the convective outflow accounts for 62% (range: 33-91%) of the observed O3. Ozone is enhanced by only 5-6% by photochemical production in the outflow due to enhanced NO from lightning, based on steady state model calculations, using in-situ observations including the first reported HOx measurements over the tropical rainforest. The "excess" ozone in the outflow is most probably due to direct production by corona discharge associated with lightning. We deduce a production rate of 5.12 × 1028 molecules O3 flash-1 (range: 9.89 × 1026-9.82 × 1028 molecules O3 flash-1), which is at the upper limit of the range of the values reported previously.

    Full Text Available In this study, the effects of school policies and practices on math achievement growth, as students transitioned from middle to high school, were examined while controlling for school contextual variables. A pattern of accelerated growth in mathematics achievement from grades 8 to 12 occurred, in which higher achieving students in mathematics at grade eight accelerated more than lower achieving students in mathematics growth during the transition from middle to high school. Controlling for school context, school policy promoting parent involvement and academic counseling had significant positive impacts on the acceleration in growth during this period. The implications of using multilevel growth models to study growth during transition periods are discussed.

    2002-01-01

    For dielectric barrier discharge lamps filled with various gas mixture ratios, the correlations between the excimer XeCl emission and the sealed gas temperature have been founded, and a qualitative explication is presented. For gas mixture with chlorine larger than 3%, the emission intensity increases with the sealed gas temperature, while with chlorine about 2%, the emission intensity decreases with the increasing in the gas temperature, and could be improved by cooling water. However, if chlorine is less than 1.5%, the discharge appears to be a mixture mode with filaments distributed in a diffused glow-like discharge, and the UV emission is independent on the gas temperature

  17. The Influence of Low-Barrier and Voluntary Service Policies on Survivor Empowerment in a Domestic Violence Housing Organization.

    The purpose of community-based domestic violence crisis housing programs (e.g., shelters) is to provide a safe setting that promotes empowerment for survivors of intimate partner violence. For staff to reach this aim, the program must have formal structures and processes in place to support such efforts. This study explored how low-barrier and voluntary service policies influenced staff practices and survivor empowerment. Low-barrier policies require that programs remove barriers that prevent survivors, particularly those who have mental health concerns and/or addictions, from being able to access services. A voluntary service policy states that survivors have the right to choose which services, if any, they would like to engage in during their stay at the program. Survivors' ability to stay at the housing program is not contingent on their participation in program services. This exploratory-sequential (QUAL→ quan) mixed-method study examined how low-barrier and voluntary service policies influenced staff behavior and how these behaviors then related to survivor empowerment. Qualitative results revealed that low-barrier and voluntary service were guided by cultural values of justice and access, encouraged survivor-centered practices among staff, and were believed to promote survivor autonomy. Quantitative results suggested that when survivors perceived they had a choice to engage in program services or meet with an advocate, their empowerment increased. This study has implications for domestic violence organizational practice and provides evidence about the contextual factors that support individual empowerment.

  20. Global Dimensions of Gifted and Talented Education: The Influence of National Perceptions on Policies and Practices

    Directory of Open Access Journals (Sweden)

    Brian L. Heuser

    2017-04-01

    Full Text Available We examine recent research across countries and cultures in regard to the issues related to the formation of gifted and talented education perspectives, policies, and practices. Many modern cultures and subcultures have developed formal and informal definitions of what it means to be gifted and talented, and when we compare the perceptions, policies, and practices across nations, we discover very different constructs of intelligence and ability. These understandings of giftedness and gifted and talented education can be grouped into four binary dimensions, scholarly versus co-curricular capabilities, aptitude versus achievement, nature versus nurture, and individualistic versus collective, that have significant implications for policy and practice. These constructs can serve as a foundation for countries that are looking to formalize or expand their gifted and talented education models or can be used to challenge the norms of established systems. We put forward recommendations to address some of the challenges in advancing gifted education cross-nationally, an area that is often assumed to introduce risks of enlarging social inequity. We also provide a cross-national matrix that captures known elements of gifted education policies and programs from over 20 subnational jurisdictions, countries, and world regions.

    Full Text Available It is important to consider the port development throughoutthe world from the aspect of economical, transport and portpolicy and their mutual impact on commerce and efficiency ofports. By examining such relations in the context of developmentof the Croatian container ports, it is possible to define reasonsfor lagging behind of Croatian ports compared to theworld movements.The main reason for the negative trend of development ofCroatian container ports lies in the non-existence of adequatemeasures of transport, maritime and port policy. Analysis ofstatistics over the past decade and comparison of structure andvolume of the general cargo traffic in the Rijeka port and theneighbouring ports in the area of North Adriatic are both showingsignificant size discrepancy and uncompetitiveness of theCroatian port. Disturbances that have brought to such a situationresult from inadequate port policy and non-harmonisedactivities between various modes of transport.In order to overcome such situation, the authors suggest determiningof clear tasks, goals and measures of the port policythat have to be undertaken so that the Croatian policy could becompatible with the main aspects, development tendencies andmeasures of theE U port policy.

  8. The influence of fiscal rules on healthcare policy in the United States and the Netherlands.

    2017-10-01

    Governments use fiscal rules to put a framework and limits on how budgetary challenges are addressed, but the rules themselves are still an understudied area among health policy scholars. For a long time, healthcare held a somewhat separate status because of the reliance on entitlements and dedicated revenue streams. However, the combined forces of advocates for integral decision-making, central budget control and the increasing costs might shift healthcare towards budgetary frameworks that currently apply to other spending categories. In this paper, we study fiscal rules that the US and the Netherlands have adopted since 2010 and their impact on healthcare policy. Our analysis shows that fiscal rules can have an impact on the rationing of healthcare. In the studied timeframe, the rules seem to have more impact on budget outcomes than on the budget process itself. In addition, the convergence of fiscal and program policy objectives seems to be better accomplished in a budgetary system that applies enforceable budget ceilings. Budgeting for health entitlements requires a comprehensive and tailor-made approach and the composition of traditional rules might not fully answer to the complexities of healthcare policy. This paper aims to contribute to that debate and the way we think about healthcare budgeting. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

  10. The influence of korean nurses' immigration into Germany on the nursing culture and policy of the countries: a transnational perspective.

    Science.gov (United States)

    Sim, Na Hye

    2013-04-01

    While many studies have addressed the Korean nurse immigration to Germany in 1960s-70s in terms of the nurses' personal histories from a national perspective, few studies have pointed to its transnational impact on the medical field. Given this gap, the paper discusses its significance in the medical history through examining the nursing culture and policy changes made in both countries initiated by the immigration of the qualified Korean nurses. For this end, the paper first discusses differences between Korea and Germany in the nursing culture and professional standards at the time of the nurse immigration. The study then examines the transnational changes in the two nations in the nursing professional culture and related policies including nurse education and qualification process. More specifically, the paper argues that the Korean female nurses not only supplied labor in need but also contributed to the medical policy changes in Germany. The prevalent stereotype of nursing as a non-professional field in the German society begin to change while experiencing professionally qualified Asian immigrant nurses and practiced treatments that had been conduced by German doctors by then. This observation actually leads to the policy level reforms in nursing education and qualification process to meet the need of high-quality nurses when the labor immigration was stopped in mid-1970s. The paper also points out that the influence of the nurse immigration on the Korean society is not merely economic; it brought the policy level reforms in nurse education and qualification as well. The immigration, resulting in a lack of nurses in the Korean society, triggered two main responses: the expansion of the existing nurse education system and the establishment of a new system called "nursing assistant."

  11. Factors influencing the technology upgrading and catch-up of Chinese wind turbine manufacturers: Technology acquisition mechanisms and government policies

    Qiu, Yueming; Ortolano, Leonard; David Wang, Yi

    2013-01-01

    This paper uses firm level data for the Chinese wind turbine manufacturing industry from 1998 to 2009 to quantify the effects of technology acquisition mechanisms – purchasing production licenses from foreign manufacturers, joint design with foreign design firms, joint-ventures and domestic R and D – on wind turbine manufacturers' technology levels (as measured by turbine size, in megawatts). It also examines the impacts of government policies on manufacturer technology levels. Technology upgrading (measured by increase of turbine size) and catch-up (measured by decrease in the distance to the world technology frontier in terms of turbine size) are used to measure advances in technology level. Results from econometric modeling studies indicate that firms' technology acquisition mechanisms and degree of business diversification are statistically significant factors in influencing technology upgrading. Similar results were found for the catch-up variable (i.e., distance to the world technology frontier). The influence of government policies is significant for technology upgrading but not catch-up. These and other modeling results are shown to have implications for both policymakers and wind turbine manufacturers. - Highlights: ► Technology acquired through joint design has the highest level. ► Technology acquired through purchasing production license has the lowest level. ► Technology acquired through domestic R and D has the level in between. ► A firm with related other businesses tends to have a higher level of technology. ► The influence of policies is significant for technology upgrade but not catch-up

    Pogorletskiy Aleksandr Igorevich

    2014-12-01

    Full Text Available The problems analyzed in the article are new to the domestic financial and tax research due to their emergent character. The article considers the influence of geopolitical factors on the tax policy of the Russian Federation and marks the most visible implemented or prospective changes in the Russian tax system under the influence of the facts and circumstances related to the geopolitical component of modern development. The focus is made on the three factors of geopolitical nature, the influence of which on public finances and taxes of Russia has already been or may be the most noticeable in the future. These factors include the growth of military spending on the backdrop of escalating tensions in the political relations between Russia and Western countries; the exchange of trade and economic sanctions between Russia and Western countries; the pursuit of enhanced tax sovereignty of the regions in the framework of the current centralized model of fiscal federalism. The possible consequences of the policy of sanctions imposed as the result of the new round of geopolitical confrontation between Russia and Western countries are analyzed. Among these consequences we should name the use of tax incentives to compensate the losses of exporters; the use of tax regulators at the financial market; the search for new sources of tax revenues for regional budgets; anti-offshore policy in relation to the Russian tax residents; the limitation of the benefits of using the consolidated groups of taxpayers; the possibility of creating a special (free economic zone in Crimea with the regime of preferential taxation. It is proved that the manifestation of geopolitics requires the serious understanding of its consequences in all spheres, including the system of public finances and taxes.

    Alcohol is a major contributor to the Non-Communicable Disease burden in South Africa. In 2000, 7.1% of all deaths and 7% of total disability-adjusted life years were ascribed to alcohol-related harm in the country. Regulations proposed to restrict alcohol advertising in South Africa present an evidence-based upstream intervention. Research on policy formulation in low- and middle-income countries is limited. This study aims to describe and explore the policy formulation process of the 2013 draft Control of Marketing of Alcoholic Beverages Bill in South Africa between March 2011 and May 2017. Recognising the centrality of affected actors in policy-making processes, the study focused on the alcohol industry as a central actor affected by the policy, to understand how they-together with other actors-may influence the policy formulation process. A qualitative case study approach was used, involving a stakeholder mapping, 10 in-depth interviews, and review of approximately 240 documents. A policy formulation conceptual framework was successfully applied as a lens to describe a complex policy formulation process. Key factors shaping policy formulation included: (1) competing and shared values-different stakeholders promote conflicting ideals for policymaking; (2) inter-department jostling-different government departments seek to protect their own functions, hindering policy development; (3) stakeholder consultation in democratic policymaking-policy formulation requires consultations even with those opposed to regulation and (4) battle for evidence-evidence is used strategically by all parties to shape perceptions and leverage positions. This research (1) contributes to building an integrated body of knowledge on policy formulation in low- and middle-income countries; (2) shows that achieving policy coherence across government departments poses a major challenge to achieving effective health policy formulation and (3) shows that networks of actors with commercial and

    Water distribution systems are one of the basic elements of contemporary technical infrastructure of urban and rural areas. It is a complex engineering system composed of transmission networks and auxiliary equipment (e.g. controllers, checkouts etc.), scattered territorially over a large area. From the water distribution system operation point of view, its basic features are: functional variability, resulting from the need to adjust the system to temporary fluctuations in demand for water and territorial dispersion. The main research questions are: What external factors should be taken into account when developing an effective water distribution policy? Does the size and nature of the water distribution system significantly affect the exploitation policy implemented? These questions have shaped the objectives of research and the method of research implementation.

  17. What factors influence smoking prevalence and smoke free policy enactment across the European Union Member States.

    Directory of Open Access Journals (Sweden)

    Ilze Bogdanovica

    Full Text Available BACKGROUND: Smoking prevention should be a primary public health priority for all governments, and effective preventive policies have been identified for decades. The heterogeneity of smoking prevalence between European Union (EU Member States therefore reflects, at least in part, a failure by governments to prioritise public health over tobacco industry or possibly other financial interests, and hence potentially government corruption. The aims of this study were to test the hypothesis that smoking prevalence is higher in countries with high levels of public sector corruption, and explore the ecological association between smoking prevalence and a range of other national characteristics in current EU Member States. METHODS: Ecological data from 27 EU Member States were used to estimate univariate and multivariate correlations between smoking prevalence and the Transparency International Corruption Perceptions Index, and a range of other national characteristics including economic development, social inclusion, quality of life and importance of religion. We also explored the association between the Corruption Perceptions Index and measures of the extent to which smoke-free policies have been enacted and are enforced. RESULTS: In univariate analysis, smoking prevalence was significantly higher in countries with higher scores for corruption, material deprivation, and gender inequality; and lower in countries with higher per capita Gross Domestic Product, social spending, life satisfaction and human development scores. In multivariate analysis, only the corruption perception index was independently related to smoking prevalence. Exposure to tobacco smoke in the workplace was also correlated with corruption, independently from smoking prevalence, but not with the measures of national smoke-free policy implementation. CONCLUSIONS: Corruption appears to be an important risk factor for failure of national tobacco control activity in EU countries, and

    Cambodia has been reconstructing its economy and health sector since the end of conflict in the 1990s. There have been gains in life expectancy and increased health expenditure, but Cambodia still lags behind neighbours One factor which may contribute is the efficiency of public health services. This article aims to understand variations in efficiency and the extent to which changes in efficiency are associated with key health policies that have been introduced to strengthen access to health services over the past decade. The analysis makes use of data envelopment analysis (DEA) to measure relative efficiency and changes in productivity and regression analysis to assess the association with the implementation of health policies. Data on 28 operational districts were obtained for 2008-11, focussing on the five provinces selected to represent a range of conditions in Cambodia. DEA was used to calculate efficiency scores assuming constant and variable returns to scale and Malmquist indices to measure productivity changes over time. This analysis was combined with qualitative findings from 17 key informant interviews and 19 in-depth interviews with managers and staff in the same provinces. The DEA results suggest great variation in the efficiency scores and trends of scores of public health services in the five provinces. Starting points were significantly different, but three of the five provinces have improved efficiency considerably over the period. Higher efficiency is associated with more densely populated areas. Areas with health equity funds in Special Operating Agency (SOA) and non-SOA areas are associated with higher efficiency. The same effect is not found in areas only operating voucher schemes. We find that the efficiency score increased by 0.12 the year any of the policies was introduced. This is the first study published on health district productivity in Cambodia. It is one of the few studies in the region to consider the impact of health policy changes

    Few studies have addressed the effect of gender policies on women's health and gender inequalities in health. This study aims to analyse the relationship between the orientation of public gender equality policies and gender inequalities in health in European countries, and whether this relationship is mediated by gender equality at country level or by other individual social determinants of health. A multilevel cross-sectional study was performed using individual-level data extracted from the European Social Survey 2010. The study sample consisted of 23,782 men and 28,655 women from 26 European countries. The dependent variable was self-perceived health. Individual independent variables were gender, age, immigrant status, educational level, partner status and employment status. The main contextual independent variable was a modification of Korpi's typology of family policy models (Dual-earner, Traditional-Central, Traditional-Southern, Market-oriented and Contradictory). Other contextual variables were the Gender Empowerment Measure (GEM), to measure country-level gender equality, and the Gross Domestic Product (GDP). For each country and country typology the prevalence of fair/poor health by gender was calculated and prevalence ratios (PR, women compared to men) and 95% confidence intervals (CI) were computed. Multilevel robust Poisson regression models were fitted. Women had poorer self-perceived health than men in countries with traditional family policies (PR = 1.13, 95%CI: 1.07-1.21 in Traditional-Central and PR = 1.27, 95%CI: 1.19-1.35 in Traditional-Southern) and in Contradictory countries (PR = 1.08, 95%CI: 1.05-1.11). In multilevel models, only gender inequalities in Traditional-Southern countries were significantly higher than those in Dual-earner countries. Gender inequalities in self-perceived health were higher, women reporting worse self-perceived health than men, in countries with family policies that were less oriented to gender equality

    Science.gov (United States)

    Gilmore, Anna; Collin, Jeff; Townsend, Joy

    2007-01-01

    Objectives. The International Monetary Fund encourages privatization of state-owned tobacco industries. Privatization tends to lower cigarette prices, which encourages consumption. This could be countered with effective tax policies. We explored how investment by British American Tobacco (BAT) influenced tax policy in Uzbekistan during privatization there. Methods. We obtained internal documents from BAT and analyzed them using a hermeneutic process to create a chronology of events. Results. BAT thoroughly redesigned the tobacco taxation system in Uzbekistan. It secured (1) a reduction of approximately 50% in the excise tax on cigarettes, (2) an excise system to benefit its brands and disadvantage those of its competitors (particularly Philip Morris), and (3) a tax stamp system from which it hoped to be exempted, because this would likely facilitate its established practice of cigarette smuggling and further its competitive advantage.. Conclusions. Privatization can endanger effective tobacco excise policies. The International Monetary Fund should review its approach to privatization and differentiate the privatization of an industry whose product kills from privatization of other industries.

    One of the most important transitions in the continuum of care for children is discharge to home. Optimal discharge communication between healthcare providers and caregivers (e.g., parents or other guardians) who present to the emergency department (ED) with their children is not well understood. The lack of policies and considerable variation in practice regarding discharge communication in pediatric EDs pose a quality and safety risk for children and their parents. The aim of this mixed methods study is to better understand the process and structure of discharge communication in a pediatric ED context to contribute to the design and development of discharge communication interventions. We will use surveys, administrative data and real-time video observation to characterize discharge communication for six common illness presentations in a pediatric ED: (1) asthma, (2) bronchiolitis, (3) abdominal pain, (4) fever, (5) diarrhea and vomiting, and (6) minor head injury. Participants will be recruited from one of two urban pediatric EDs in Canada. Video recordings will be analyzed using Observer XT. We will use logistic regression to identify potential demographic and visit characteristic cofounders and multivariate logistic regression to examine association between verbal and non-verbal behaviours and parent recall and comprehension. Video recording of discharge communication will provide an opportunity to capture important data such as temporality, sequence and non-verbal behaviours that might influence the communication process. Given the importance of better characterizing discharge communication to identify potential barriers and enablers, we anticipate that the findings from this study will contribute to the development of more effective discharge communication policies and interventions.

    This work examines the properties of a dielectric barrier discharge (DBD) reactor, built for CO 2 decomposition, by means of electrical characterization, optical emission spectroscopy and gas chromatography. The discharge, formed in an electronegative gas (such as CO 2 , but also O 2 ), exhibits clearly different electrical characteristics, depending on the surface conductivity of the reactor walls. An asymmetric current waveform is observed in the metal-dielectric (MD) configuration, with sparse high-current pulses in the positive half-cycle (HC) and a more uniform regime in the negative HC. This indicates that the discharge is operating in two alternating regimes with rather different properties. At high CO 2 conversion regimes, a conductive coating is deposited on the dielectric. This so-called coated MD configuration yields a symmetric current waveform, with current peaks in both the positive and negative HCs. In a double-dielectric (DD) configuration, the current waveform is also symmetric, but without current peaks in both the positive and negative HC. Finally, the DD configuration with conductive coating on the inner surface of the outer dielectric, i.e. so-called coated DD, yields again an asymmetric current waveform, with current peaks in the negative HC. These different electrical characteristics are related to the presence of the conductive coating on the dielectric wall of the reactor and can be explained by an increase of the local barrier capacitance available for charge transfer. The different discharge regimes affect the CO 2 conversion, more specifically, the CO 2 conversion is lowest in the clean DD configuration. It is somewhat higher in the coated DD configuration, and still higher in the MD configuration. The clean and coated MD configuration, however, gave similar CO 2 conversion. These results indicate that the conductivity of the dielectric reactor walls can highly promote the development of the high-amplitude discharge current pulses and

    Manual calibration is common in rainfall-runoff model applications. However, rainfall-runoff models include several complicated parameters; thus, significant time and effort are required to manually calibrate the parameters individually and repeatedly. Automatic calibration has relative merit regarding time efficiency and objectivity but shortcomings regarding understanding indigenous processes in the basin. In this study, a watershed model calibration framework was developed using an influence coefficient algorithm and genetic algorithm (WMCIG) to automatically calibrate the distributed models. The optimization problem used to minimize the sum of squares of the normalized residuals of the observed and predicted values was solved using a genetic algorithm (GA). The final model parameters were determined from the iteration with the smallest sum of squares of the normalized residuals of all iterations. The WMCIG was applied to a Gomakwoncheon watershed located in an area that presents a total maximum daily load (TMDL) in Korea. The proportion of urbanized area in this watershed is low, and the diffuse pollution loads of nutrients such as phosphorus are greater than the point-source pollution loads because of the concentration of rainfall that occurs during the summer. The pollution discharges from the watershed were estimated for each land-use type, and the seasonal variations of the pollution loads were analyzed. Consecutive flow measurement gauges have not been installed in this area, and it is difficult to survey the flow and water quality in this area during the frequent heavy rainfall that occurs during the wet season. The Hydrological Simulation Program-Fortran (HSPF) model was used to calculate the runoff flow and water quality in this basin. Using the water quality results, a load duration curve was constructed for the basin, the exceedance frequency of the water quality standard was calculated for each hydrologic condition class, and the percent reduction

  1. Cap-and-trade policy: The influence on investments in carbon dioxide reducing technologies in Indiana

    Science.gov (United States)

    Fahie, Monique

    With most of the energy produced in the state of Indiana coming from coal, the implementation of policy instruments such as cap-and-trade, which is included in the most recent climate bill, will have significant effects. This thesis provides an analysis of the effects that a cap-and-trade policy might have on the investment decisions for alternative technologies in the power plant sector in Indiana. Two economic models of representative coal-fired power plants, Gallagher (600MW) and Rockport (2600MW), are selected and used to evaluate the repowering decision of a plant for several technologies: integrated gasification combined cycle (IGCC), wind farm combined with natural gas combined cycle (NGCC) and supercritical pulverized coal (SCPC). The firm will make its decisions based on the net present value (NPV) of cost estimates for these CO2 reducing technologies, the cost of purchasing offsets and CO 2 allowances. This model is applied to a base case and three American Clean Energy and Security Act of 2009 cases derived from the Energy Information Administration (EIA, 2009b). A sensitivity analysis is done on the discount rate and capital costs. The results of the study indicate that a SCPC plant without carbon capture and storage (CCS) is the least costly compliance option for both plants under all of the cases while retrofitting the existing plant with CCS is the most expensive. Gallagher's three least expensive options across most scenarios were SCPC without CCS, the operation of the existing plant as is and investment in wind plus NGCC. Rockport's three least expensive compliance options across most scenarios were SCPC without CCS, the operation of the existing plant as is and IGCC without CCS. For both plants, when a 12% discount rate is utilized, NPV of costs are generally lower and the operation of the existing plant technology with the aid of allowances and offsets to be in compliance is the cheapest option. If capital costs were to decrease by 30%, a SCPC

  2. Legislative responses to wrongful conviction: Do partisan principals and advocacy efforts influence state-level criminal justice policy?

    The number of discovered wrongful criminal convictions (and resulting exonerations) has increased over the past decade. These cases erode public confidence in the criminal justice system and trust in the rule of law. Many states have adopted laws that aim to reduce system errors but no study has examined why some states appear more willing to provide due process protections against wrongful convictions than others. Findings from regression estimates suggest that states with a Republican controlled legislature or more Republican voters are less likely to pass these laws while the presence of advocacy organizations that are part of the 'innocence movement' make legislative change more likely. We thus identify important differences in the political and social context between U.S. states that influence the adoption of criminal justice policies. Copyright © 2015 Elsevier Inc.

    The aim of our study was to investigate the changes in drug usage and financial expenditure according to legal changes in Croatia during the period 2001 - 2008, especially considering pricing policy. The data on outpatient drug usage during the studied period was obtained from the Croatian National Health Insurance (CNHI). CNHI maintains a database on drugs prescribed by primary health care physicians and dispensed by pharmacies. The data was calculated and presented in defined daily doses (DDD) per inhabitant per year for antibiotics and in DDD/1,000 inhabitants/day for other drugs. The data is also presented in Euro/DDD and the financial expenditures are presented in Euros. During the investigated period drug usage increased 81.33%, while financial expenditure increased 77.23%. While total DDD/1,000 increased ~ 10% every year, financial expenditure increased 10 - 20% annually until 2006, but since then there have been no significant changes. Pricing policy changes could influence drug financial expenditure considerably in the short-term, but it is also important to apply a combination of measures for drug expenditure control. Numerous interventions from authorities from different countries all over the world, prove that there is still no so called "gold standard" which could restrain growing usage and expenditure of drugs. Clinical pharmacologists and clinical pharmacists should be included in these processes.

    Political and economical changes in Poland are accompanied by substantial transition of ecological policy of the state. A first sign of that policy is new law defining responsibilities of companies in minimising the environmental impacts of new investments and duties concerning waste management and disposal as well as pollutant emission reduction. These more stringent environmental rules influence force the Polish gas industry to fulfill new ecological requirements and, because of high ecological value of gas, they give it promising prospects of development. Since environmental condition improvement in Poland can not be achieved without the change in primary energy consumption structure the Gas Development Programme has been established. It assumes more than double increase in gas consumption up to 2010. Gas industry duties connected with environmental requirements have been presented and activities taken in order to meet ecological law rules have been specified for all stages of gas fuel chain from exploration to gas usage. Some measures taken to prevent environment damages have been discussed like ecological evaluation of drilling materials and wastes, elaborated strategy for water protection and Environmental Impact Assessment procedure. The problem of methane emissions from Polish gas system has also been discussed. (au)

    The sensitivity of xenon ionization rates to collision cross-sections is studied within the framework of a hybrid-PIC model of a Hall thruster discharge. A revised curve fit based on the Drawin form is proposed and is shown to better reproduce the measured crosssections at high electron energies, with differences in the integrated rate coefficients being on the order of 10% for electron temperatures between 20 eV and 30 eV. The revised fit is implemented into HPHall and the updated model is used to simulate NASA's HiVHAc EDU2 Hall thruster at discharge voltages of 300, 400, and 500 V. For all three operating points, the revised cross-sections result in an increase in the predicted thrust and anode efficiency, reducing the error relative to experimental performance measurements. Electron temperature and ionization reaction rates are shown to follow the trends expected based on the integrated rate coefficients. The effects of triply-charged xenon are also assessed. The predicted thruster performance is found to have little or no dependence on the presence of triply-charged ions. The fraction of ion current carried by triply-charged ions is found to be on the order of 1% and increases slightly with increasing discharge voltage. The reaction rates for the 0?III, I?III, and II?III ionization reactions are found to be of similar order of magnitude and are about one order of magnitude smaller than the rate of 0?II ionization in the discharge channel.

  6. The influence of the N(2D) and N(2P) states in the ionization of the pink afterglow of the nitrogen flowing DC discharge

    In the present work, we extensively discuss the role of N(2D) and N(2P) atoms in the ionization processes of pink afterglow based on optical emission spectroscopy analysis and kinetic numerical modelling. We studied the pink afterglow generated by a nitrogen DC discharge operating at 0.6 Slm-1 flow rate, 45 mA discharge current and pressures ranging from 250 to 1050 Pa. The 391.4 nm nitrogen band was monitored along the afterglow furnishing the relative density of the N2+(B2Σ+u, v = 0) state. A numerical model developed to calculate the nitrogen species densities in the afterglow fits the excited ion density profiles well for the experimental conditions. From the modelling results, we determine the densities of the N+, N2+, N3+, and N4+ ions; the calculations show that the N3+ ion density predominates in the afterglow at the typical residence times of the pink afterglow. This behaviour has been observed experimentally and reported in the literature. Furthermore, we calculate the fractional contribution in the ionization for several physical-chemical mechanisms in the post-discharge. Even with the N3+ ion density being dominant in the afterglow, we find through the calculations that the ionization is dominated by the reactions N(2D) + N(2P) → N2+(X2Σ+g) + e and N2(a'1Σ-u) + N2(X 1Σg+, v > 24) → N4+ + e. The ion conversion mechanisms, or ion transfer reactions, which are responsible for the fact that the N3+ density dominates in the post-discharge, are investigated.

    In this paper, an oscillating microsecond pulsed power supply with rise time of several tens of nanosecond (ns) is used to excite a coaxial DBD with double layer dielectric barriers. The effects of various electrode geometries by changing the size of inner quartz tube (different electrode gaps) on the discharge uniformity, power deposition, energy efficiency, and operation temperature are investigated by electrical, optical, and temperature diagnostics. The electrical parameters of the coaxial DBD are obtained from the measured applied voltage and current using an equivalent electrical model. The energy efficiency and the power deposition in air gap of coaxial DBD with various electrode geometries are also obtained with the obtained electrical parameters, and the heat loss and operation temperature are analyzed by a heat conduction model. It is found that at the same applied voltage, with the increasing of the air gap, the discharge uniformity becomes worse and the discharge power deposition and the energy efficiency decrease. At 2.5 mm air gap and 24 kV applied voltage, the energy efficiency of the coaxial DBD reaches the maximum value of 68.4%, and the power deposition in air gap is 23.6 W and the discharge uniformity is the best at this case. The corresponding operation temperature of the coaxial DBD reaches 64.3 °C after 900 s operation and the temperature of the inner dielectric barrier is 114.4 °C under thermal balance. The experimental results provide important experimental references and are important to optimize the design and the performance of coaxial DBD reactor.

    Self-organized luminous pattern formation is observed in the liquid surface of an atmospheric dc glow discharge using a liquid electrode with a miniature helium flow. The factors affecting pattern formation are the gap length, discharge current, helium mass flow rate and polarity. The pattern shape depends on the conductivity and temperature of the liquid electrode. A variety of patterns were observed by changing the conductivity and temperature of the liquid. We clarified that the self-organized pattern formation depends on the amount of electronegative gas, such as oxygen, in the gas in the electrode gap. When an oxygen gas flow was fed to the liquid surface from the outside in an obliquely downward direction, namely, the amount of oxygen gas on the liquid surface was increased locally, self-organized pattern formation was observed in the region with the increased amount of oxygen gas. When the amount of oxygen in the gas in the gap was changed by using a sheath flow system, the appearance of the pattern changed. The presence of oxygen gas strongly affected the self-organized pattern formation of the atmospheric dc discharge using a liquid anode. (paper)

    Increasing numbers of homes are being destroyed by wildfire in the wildland-urban interface. With projections of climate change and housing growth potentially exacerbating the threat of wildfire to homes and property, effective fire-risk reduction alternatives are needed as part of a comprehensive fire management plan. Land use planning represents a shift in traditional thinking from trying to eliminate wildfires, or even increasing resilience to them, toward avoiding exposure to them through the informed placement of new residential structures. For land use planning to be effective, it needs to be based on solid understanding of where and how to locate and arrange new homes. We simulated three scenarios of future residential development and projected landscape-level wildfire risk to residential structures in a rapidly urbanizing, fire-prone region in southern California. We based all future development on an econometric subdivision model, but we varied the emphasis of subdivision decision-making based on three broad and common growth types: infill, expansion, and leapfrog. Simulation results showed that decision-making based on these growth types, when applied locally for subdivision of individual parcels, produced substantial landscape-level differences in pattern, location, and extent of development. These differences in development, in turn, affected the area and proportion of structures at risk from burning in wildfires. Scenarios with lower housing density and larger numbers of small, isolated clusters of development, i.e., resulting from leapfrog development, were generally predicted to have the highest predicted fire risk to the largest proportion of structures in the study area, and infill development was predicted to have the lowest risk. These results suggest that land use planning should be considered an important component to fire risk management and that consistently applied policies based on residential pattern may provide substantial benefits for

    The need to understand and minimize negative environmental outcomes associated with large dams has both contributed to and benefited from the introduction and subsequent improvements in the Environmental Impact Assessment (EIA) process. However, several limitations in the EIA process remain, including those associated with the uncertainty and significance of impact projections. These limitations are directly related to the feedback between science and policy, with information gaps in scientific understanding discovered through the EIA process contributing valuable recommendations on critical focus areas for prioritizing and funding research within the fields of ecological conservation and river engineering. This paper presents an analysis of the EIA process for the Three Gorges Project (TGP) in China as a case study for evaluating this feedback between the EIA and science and policy. For one of the best-studied public development projects in the world, this paper presents an investigation into whether patterns exist between the scientific interest (via number of publications) in environmental impacts and (a) the identification of impacts as uncertain or priority by the EIA, (b) decisions or political events associated with the dam, and (c) impact type. This analysis includes the compilation of literature on TGP, characterization of ecosystem interactions and responses to TGP through a hierarchy of impacts, coding of EIA impacts as "uncertain" impacts that require additional study and "priority" impacts that have particularly high significance, mapping of an event chronology to relate policies, institutional changes, and decisions about TGP as "events" that could influence the focus and intensity of scientific investigation, and analysis of the number of publications by impact type and order within the impact hierarchy. From these analyses, it appears that the availability and consistency of scientific information limit the accuracy of environmental impact

    Retinal input processing in the human visual system involves a phasic and tonic neural response. We investigated the role of the magno- and parvocellular systems by comparing the influence of the active neural population size and its discharge activity on the amplitude and latency of four VEP components. We recorded the scalp electric potential of 20 human volunteers viewing a series of dartboard images presented as a pattern reversing and pattern on-/offset stimulus. These patterns were designed to vary both neural population size coding the temporal- and spatial luminance contrast property and the discharge activity of the population involved in a systematic manner. When the VEP amplitude reflected the size of the neural population coding the temporal luminance contrast property of the image, the influence of luminance contrast followed the contrast response function of the parvocellular system. When the VEP amplitude reflected the size of the neural population responding to the spatial luminance contrast property the image, the influence of luminance contrast followed the contrast response function of the magnocellular system. The latencies of the VEP components examined exhibited the same behavior across our stimulus series. This investigation demonstrates the complex interplay of the magno- and parvocellular systems on the neural response as captured by the VEP. It also demonstrates a linear relationship between stimulus property, neural response, and the VEP and reveals the importance of feedback projections in modulating the ongoing neural response. In doing so, it corroborates the conclusions of our previous study.

    Presently, renewable energies and especially wind energy are gaining a special relevance in the electrical market worldwide. This current rate of growth brings with it the need for the various wind farms to not limit themselves to producing energy but also provide stability to the network within its capabilities. So, the actual objective is to adapt the installations that produce wind energy in such a way that they give a maximum amount of support in any given moment to the electrical network. For this purpose, there are governing techno-economic parameters that influence the economic behavior of commercial wind farms. A complete cost-benefit analysis model is developed, focused on incorporating automatic capacitor banks into wind farms for the compensation of reactive power. This economic analysis is about doubly fed induction generator (DFIG) wind turbines. Although this kind of wind turbines have a certain capability in terms of modulating reactive power, this capacity is not enough to achieve the new requirements of reactive power regulation in Spain and it is necessary to invest in systems of external compensation. In this paper, we have studied the case of DFIG wind turbine and capacitor banks, although the used methodology can be applied to other technologies as well by simply amplifying the algorithms according to the specific characteristics of the option elected. Following this premise, a detailed analysis of the specific needs of a wind farm has been carried out, as well as a search for the optimum performance for the compensation of reactive power.

    Full Text Available Work-family reconciliation plays a crucial role in the well-being of employees, having impacts at the individual, social and organizational level. Studies concluded that poor work-life balance as one of the ten predictors of psychosocial risks at work. A family-friendly culture relates to how an organization values and allows the articulation of the various spheres of its workers’ life. We intended to determine the effect of different variables like the existence of services, the organizational culture and the managers and colleagues support, on the stress experienced. A sample of 156 employees, from five organizations in the same region of Portugal, responded to a survey contributing to the empirical results of the study. We have conducted a structural equation model to test whether the factor solution of the perception of the reconciliation capability - STRESS model demonstrated a goodness of fit to the population studied. We’ve concluded that more important than the existence of reconciliation services, the perception of a supportive organizational culture, namely by colleagues and supervisors has great influence in reconciliation capability and by that way on work stress feelings. This might explain why workers do not use all the spectrum of resources provided by organizations and states to work-life reconciliation.

  17. A Systematic Review of the Factors Influencing Ethnic Minority Women's Cervical Cancer Screening Behavior: From Intrapersonal to Policy Level.

    Chan, Dorothy N S; So, Winnie K W

    Cervical cancer can be prevented by effective screening using Papanicolaou tests, but the utilization rate is lower among ethnic minorities than in the general population. Understanding the factors influencing minorities' use of such screening can aid the design of an appropriate intervention to increase their uptake rate. The aims of this study were to examine the factors that influence ethnic minority women in using cervical cancer screening and the similarities and differences in associated factors across different groups and to explore the interrelationships between the factors identified. A literature search was conducted using Ovid MEDLINE, Cumulative Index to Nursing and Allied Health Literature Plus, Scopus, PsycINFO, and PubMed. Furthermore, 1390 articles were retrieved, of which 24 met the inclusion criteria. Critical appraisal was performed by means of a quality assessment tool. The findings were summarized in tabular and narrative forms. The findings showed that certain factors commonly affected ethnic minority women's screening behavior, including knowledge, attitude and perceptions, physician's recommendation, quality of care and service, language, and acculturation. Culture-related factors, religion, and acculturation exhibited close interrelationships with the attitude and perceptions factor, resulting in behavioral change. The review sheds light on how common or unique are the factors across ethnic minorities and how these factors interact to influence behavior. Further studies are warranted to develop and test empirically a comprehensive model leading to a better understanding of the interrelationships between multiple factors. The model should be useful in informing policy makers about appropriate resource allocation and in guiding the development of culturally relevant programs to increase screening uptake.

    Proposed climate mitigation measures do not account for direct biophysical climate impacts of land-use change (LUC), nor do the stabilization targets modeled for the 5th Climate Model Intercomparison Project (CMIP5) Representative Concentration Pathways (RCPs). To examine the significance of such effects on global and regional patterns of climate change, a baseline and alternative scenario of future anthropogenic activity are simulated within the Integrated Earth System Model, which couples the Global Change Assessment Model, Global Land-use Model, and Community Earth System Model. The alternative scenario has high biofuel utilization and approximately 50% less global forest cover compared to the baseline, standard RCP4.5 scenario. Both scenarios stabilize radiative forcing from atmospheric constituents at 4.5 W/m2 by 2100. Thus, differences between their climate predictions quantify the biophysical effects of LUC. Offline radiative transfer and land model simulations are also utilized to identify forcing and feedback mechanisms driving the coupled response. Boreal deforestation is found to strongly influence climate due to increased albedo coupled with a regional-scale water vapor feedback. Globally, the alternative scenario yields a 21st century warming trend that is 0.5 °C cooler than baseline, driven by a 1 W/m2 mean decrease in radiative forcing that is distributed unevenly around the globe. Some regions are cooler in the alternative scenario than in 2005. These results demonstrate that neither climate change nor actual radiative forcing are uniquely related to atmospheric forcing targets such as those found in the RCP’s, but rather depend on particulars of the socioeconomic pathways followed to meet each target.

    The plasma sheath near the surface of a hypersonic aircraft formed under associative ionization behind the shock front shields the transmission and reception of radio signals. Using two-dimensional kinetic particle-in-cell simulations, we consider the change in plasma-sheath parameters near a flat surface in a hypersonic flow under the action of electrical and magnetic fields. The combined action of a high-frequency 2-MHz capacitive discharge, a constant voltage, and a magnetic field on the plasma sheath allows the local electron density to be reduced manyfold.

    The Green Deal is a major new energy policy designed to support the diffusion of energy efficiency measures in UK homes. This paper provides one of the first empirical examinations of the Green Deal′s success in influencing homeowners’ renovation decisions. Using a repeated measures design in which households were questioned before and after the Green Deal′s launch in January 2013, we assess the policy′s success in raising awareness of energy efficiency. In particular, we test the effectiveness of the Green Deal′s positioning to overcome barriers to renovation among homeowners already interested in or considering energy efficiency measures. Using the innovation decision process (Rogers, 2003) as a conceptual framing of the renovation decision process, we examine whether new information on energy efficiency provided by the Green Deal strengthened intentions and its antecedents. We find that (1) energy efficiency is of potential appeal to all renovators regardless of their attitudes about energy efficiency, (2) energy efficiency opportunities need to be identified in the early stages of renovation when homeowners are thinking about ways to improve their home, and (3) homeowners’ intentions towards energy efficiency are weakened by uncertainty about financial benefits, helping to explain the relatively slow uptake of the Green Deal to-date. - Highlights: • Examines the impact of a major new energy policy, the Green Deal, on intentions towards energy efficiency. • 502 households questioned four months prior to, and seven months after the launch. • Renovating itself is mechanism through which households engage with the Green Deal. • Strengthening beliefs in energy savings accelerates intentions to renovate energy efficiently

    Migrant sex workers are often highly marginalized and disproportionately experience health and social inequities, including high prevalence of HIV, sexually transmitted infections, and human rights violations. In recent years, research involving migrant sex workers has increased, yet many knowledge gaps remain regarding how best to protect research participant rights and welfare. Our objective was to identify key challenges and opportunities related to the responsible conduct of HIV research with migrant sex workers. Focus groups and interviews conducted with 33 female sex workers ≥18 years old at the Guatemala-Mexico border from June 2013-February 2014 were analyzed. Participants were recruited through community outreach by a local HIV prevention organization to sex work establishments such as bars, hotels, street corners, and truck stops. Key themes influencing research engagement for migrant sex workers included researcher mistrust and fear related to research participation, rooted in the social isolation frequently faced by recent migrants; intersecting concerns related to immigration status, fear of criminalization, and compliance with sex work regulations; and perceived benefits and risks of HIV/STI testing for migrants (e.g., immigration implications, stigma) represent potential barriers and opportunities for the responsible conduct of research involving migrant sex workers. Results highlight the intersection between the human rights vulnerabilities of migrant sex workers and barriers to research participation, including social isolation of migrants and policy/legal barriers related to immigration and sex work. Findings illustrate the need for researchers to develop population-tailored procedures to address fears related to immigration and criminalization, and to reinforce positive and non-stigmatizing relationships with migrant sex workers.

    Counseling for patients with cancer by a certified nurse in palliative care began in April 2011 in Minoh City Hospital. Counseling was provided immediately after a patient was informed by the treating physician of a primary diagnosis of cancer, a metastatic recurrence, or a decision to terminate cancer therapy. We examined the patient's support system after the counseling ended. The number of patients receiving end-of-life support with home or hospital care rapidly increased from 118 prior to the program's beginning to 186. The number of patients counseled was comparable to the rapid increase in their number(n=68). New cases in the outpatient department comprised 59% of all patients, of which, 45% began supportive counseling, with 43%of them ultimately returning home. Of the new cases receiving counseling in the hospital, 34%eventually returned home after discharge, and the highest percentage of discharges were to a palliative care unit or hospice program (48%). The initiation of counseling in the outpatient department allowed us to provide sufficient time to make decisions about appropriate places for end-of-life care. Cooperation with the patients' physicians was necessary to provide counseling from the outpatient department. Our findings suggest the importance of sharing the patients' medical and social information among the staff when necessary.

    Harmful gambling is a public health issue that affects not only adults but also children. With the development of a range of new gambling products, and the marketing for these products, children are potentially exposed to gambling more than ever before. While there have been many calls to develop strategies which protect children from harmful gambling products, very little is known about the factors that may influence children's attitudes towards these products. This study aimed to explore children's gambling attitudes and consumption intentions and the range of consumer socialisation factors that may influence these attitudes and behaviours. Children aged 8 to 16 years old (n = 48) were interviewed in Melbourne, Australia. A semi-structured interview format included activities with children and open-ended questions. We explored children's perceptions of the popularity of different gambling products, their current engagement with gambling, and their future gambling consumption intentions. We used thematic analysis to explore children's narratives with a focus on the range of socialising factors that may shape children's gambling attitudes and perceptions. Three key themes emerged from the data. First, children's perceptions of the popularity of different products were shaped by what they had seen or heard about these products, whether through family activities, the media (and in particular marketing) of gambling products, and/or the alignment of gambling products with sport. Second, children's gambling behaviours were influenced by family members and culturally valued events. Third, many children indicated consumption intentions towards sports betting. This was due to four key factors: (1) the alignment of gambling with culturally valued activities; (2) their perceived knowledge about sport; (3) the marketing and advertising of gambling products (and in particular sports betting); and (4) the influence of friends and family. This study indicates that there is

    The effects of Li2CO3 like species originating from reactions between CO2 and Li2O2 at the cathode of non-aqueous Li-air batteries were studied by density functional theory (DFT) and galvanostatic charge-discharge measurements. Adsorption energies of CO2 at various nucleation sites on a stepped (1......‾100) Li2O2 surface were determined and even a low concentration of CO2 effectively blocks the step nucleation site and alters the Li2O2 shape due to Li2CO3 formation. Nudged elastic band calculations show that once CO2 is adsorbed on a step valley site, it is effectively unable to diffuse and impacts...

    Contaminants of emerging concern were measured in mussels collected along the California coast in 2009-2010. The seven classes were alkylphenols, pharmaceuticals and personal care products, polybrominated diphenyl ethers (PBDE), other flame retardants, current use pesticides, perfluorinated compounds (PFC), and single walled carbon nanotubes. At least one contaminant was detected at 67 of the 68 stations (98%), and 67 of the 167 analytes had at least one detect (40%). Alkylphenol, PBDE, and PFC concentrations increased with urbanization and proximity to storm water discharge; pesticides had higher concentrations at agricultural stations. These results suggest that certain compounds; for example, alkylphenols, lomefloxacin and PBDE, are appropriate for inclusion in future coastal bivalve monitoring efforts based on maximum concentrations >50 ng/g dry weight and detection frequencies >50%. Other compounds, for example PFC and hexabromocyclododecane (HBCD), may also be suggested for inclusion due to their >25% detection frequency and potential for biomagnification.

    The effect of argon/oxygen atmospheric dielectric barrier discharge (DBD) treatment on desizing and scouring of polyvinyl alcohol (PVA) on cotton fabric was studied with respect to the treatment duration of 1, 2, 4 and 6 min. X-ray photoelectron spectroscopy (XPS) analysis indicated that oxygen concentration increased for the plasma treated PVA film. Solubility measurement revealed that plasma treatment increased PVA solubility in hot washing but less effective in cold washing. Scanning electron microscopy (SEM) showed that the fiber surfaces were as clean as unsized fibers after 6 min treatment followed by hot washing. Wickability analysis indicated that the capillary heights of plasma treated fabrics increased significantly as the plasma treatment duration increased. The results of the yarn tensile strength test showed that the plasma treatment did not have a negative effect on fabric tensile strength.

    In the research, it is argued that the targeted promotion of renewables leads to a change in the technological path dependency on the electricity market or led. The historically market depending portfolio of products in the conventional power industry will be replaced by an increasingly strong dependence on the product portfolio of Renewable Energy Sector according to this argumentation. The present work is devoted to the political explanation of the change and transition process in the electricity market. The process of policy formation in this market (especially support policies for renewable energies) will be discussed. It is examined from a public choice perspective, which political actors and instances in the past were responsible for the development and maintenance of individual policy elements. In particular, in this analysis the different private sector stakeholders in the electricity market move to center of attention. [de

    The experimental technique consists in estimation of mutual arrangement of the calibration curves obtained using standard reference materials of low-alloyed and high-alloyed (high-chrome, stainless, high-speed) steels as well as of the curves for carbon steels and cast iron differing in their structure. ARL-31000 and Polyvac E-1000 quantometers with U=1300 V, I=0.12 A and argon pressure ∼1 kPa are used. The influence of third elements is shown in shift and slope changes of the curves for abovementioned high-alloyed steels in comparison to ones for low-alloyed steels accepted as basic. The influence magnitude runs up to 10-30 relative percents and more in the case of analysis of carbon, phosphorus, sulfur, silicon and other elements and depends on the type of the element and on the alloy composition. It is shown that the contribution of structure factor caused by different alloy thermal treatment makes up 10 to 20 relative percents. The experiments showed that the increase of influence of these factors caused by their imposing as well as the weakening of this influence caused by their counteraction is possible. When analyzed alloys differ in their composition and manufacturing technology it is necessary to take into consideration the influence of these effects. (author)

    Kerner, Lucy Alexandra

    The events that started to unfurl in the former Soviet Union in the beginning of the 1990s and that ended with the disintegration of the USSR caught many sovietologists, and specialists on former communist and socialist regimes by surprise. Major theories and analyses developed and successfully used in such areas as Comparative Politics, International Relations, and Comparative Socialism turned out to be impotent to foresee the approach of the dramatic changes. Noticing the growing significance of and influence on the policy making process of numerous bureaucracies, this study has applied alternative approaches that were developed in such fields as Organizational Theory, Bureaucratic Behavior, and Public Policy. The issue of bureaucratic performance in the former USSR became the central focal point of the study. Methods suggested by specialists in these fields permitted measurement of the performance of different bureaucratic medical institutions during and after the Chernobyl crisis. Utilization of performance measurements helped uncover several important phenomena. One, that performance of the Soviet medical institutions/organizations and bureaucracies that they housed reached an ultimate dysfunctional stage. It became counterproductive to the point that we can brand it pathological. The characteristic feature of pathological performance is that its outcomes (final results) have a totally counterproductive effect on the external environment and on the community which uses its services and/or products. In the case of Chernobyl it was medical services that were either very poorly provided to the victims of the accident or totally withheld from them The result was a manifold increase in different illnesses and deaths among the population affected by the accident. Second, behavior and performance of the medical bureaucracies in comparison with the behavior and performance of other Soviet bureaucracies has shown that it was not unique. This counterproductive behavior

    The application of powder mixed dielectric to improve the efficiency of electrical discharge machining (EDM) has been extensively studied. Therefore, PMEDM have attracted the attention of many researchers since last few decades. Improvement in EDM process has resulted in the use of span-20 surfactant and Cr powder mixed in dielectric fluid, which results in increasing machiniability, better surface quality and faster machining time. However, the study of powder suspension size of surface charateristics in EDM field is still limited. This paper presents the improvement of micro-/nano- Cr powder size on the surface characteristics of the AISI D2 hardened steels in PMEDM. It has found that the reacst layer in PMEDM improved by as high as 41-53 % compared to conventional EDM. Also notably, the combination of added Cr powder and span-20 surfactant reduced the recast layer thickness significantly especially in nano-Cr size. This improvement was great potential adding nano-size Cr powder to dielectric for machining performance.

    Entrainment (i.e., withdrawal of fish larvae and eggs in cooling water) at the SRS Savannah River intakes is greatest when periods of high river water usage coincide with low river dischargeduring the spawning season. American shad and striped bass are the two species of greatest concern because of their recreational and/or commercial importance and because they produce drifting eggs and larvae vulnerable to entrainment. In the mid-reaches of the Savannah River, American shad and striped bass spawn primarily during April and May. An analysis of Savannah River discharge during April and May 1973--1989 indicated the potential for entrainment of 4--18% of the American shad and striped bass larvae and eggs that drifted past the SRS. This analysis assumed the concurrent operation of L-, K-, and P-Reactors. Additional scenarios investigated were: (1) shutting down L- and P-Reactors, and operating K-Reactor with a recycle cooling tower; and (2) shutting down L- and P-Reactors, eliminating minimum flows to Steel Creek, and operating K-Reactor with a recycle cooling tower. The former scenario reduced potential entrainment to 0.7--3.3%, and the latter scenario reduced potential entrainment to 0.20.8%. Thus, the currently favored scenario of operating K-Reactor with a cooling tower and not operating L- and P-Reactors represents a significant lessening of the impact of SRS operations

    In this paper, the effects of inner diameters on the Z-pinch plasma of capillary discharge soft X-ray laser were investigated with the 3.2 mm and 4.0 mm inner diameter alumina capillaries. The intensities of the laser emitted from the 3.2 mm and 4.0 mm inner diameter alumina capillaries were measured under different initial pressures. To understand the underlying physics of the experimental measurements, the Z-pinch plasma simulations had been conducted with a one-dimensional cylindrical symmetry Lagrangian magneto-hydrodynamics (MHD) code. The parametric studies of Z-pinch plasma, such as the electron temperature, the electron density and the Ne-like Ar ion density, were performed with the MHD code. With the experimental and the simulated results, the discussions had been conducted on the Z-pinch plasma of Ne-like Ar 46.9 nm laser with the 3.2 mm and 4.0 mm inner diameter alumina capillaries. The analysis had been made on the difference of the gain coefficients under the optimum pressures with both capillaries. Then, the effects of inner diameters on the optimum pressure and the pressure domain were analyzed. (copyright 2015 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim)

    Numerous investigations have shown that the emission spectroscopic analysis of solutions with the use of a high-frequency inductively coupled plasma discharge is characterized by the absence of an influence or the presence of a small influence of the matrix elements on the amplitudes of the analytical signals of the elements being determined and, consequently, on the results of an analysis. The influences of the first type include the influences of easily ionized elements, which, as we know, are very significant in spectroscopic analysis with the use of traditional sources for the excitation of the spectra (arcs, sparks, and flames). The influences of the second type include, in particular, the influences associated with changes in the viscosity and surface tension of the solutions as the concentration of the matrix elements in the solutions is increased. In order to obtain correct results from an analysis in the case of spectral interference, special methods for treating the spectra are used for the purpose of taking into account the background and the instances of superposition and establishing the true (''pure'') intensity of the analytical lines. Results are shown of the Determination of impurities in aqueous solutions of sodium Molybate Single Crystals (the concentration of Na 2 Mo 2 O 7 in the solution was 1 mg/ml). When the solutions being analyzed are diluted to a concentration of Na 2 Mo 2 O 7 equal to 1 mg/ml, good agreement between the results of the determination of vanadium (and other impurities) obtained with the use of reference solutions not containing the matrix elements and the results obtained with the use of reference solutions containing the matrix elements in the same concentrations as in the solutions being analyzed (1mg/ml) was guaranteed

    Adults and adolescents who reside in rural areas of the United States are traditionally more likely to be tobacco users. This urban-rural disparity remains largely unexplained and, more recently, it is unclear what impact the emergence of electronic cigarettes (e-cigarettes) has had on adolescent tobacco use in urban and rural areas. Our objective is to evaluate the influence of sociodemographics and tobacco control policy environments on adolescent tobacco use in urban versus rural areas, as well as to identify the effect of e-cigarettes on traditional patterns of urban-rural tobacco use. This study analyzes repeated cross-sectional data from the National Youth Tobacco Survey for the years 2011-2014. We estimate the associations between rural residence, cigarette taxes, tobacco advertisement exposure, and ease of access to tobacco with six tobacco use outcomes: current (past 30-day) use of cigarettes, e-cigarettes, cigars, smokeless tobacco, multiple tobacco products, and any tobacco. E-cigarette use among urban youths aged 11-17 years in the United States increased from .82% in 2011 to 8.62% in 2014 (p e-cigarettes. Our predictors account for approximately 40% of the difference in urban-rural cigarette use. Sociodemographics, cigarette taxes, and tobacco advertisement exposure are significant predictors of adolescent tobacco use in the United States but do not entirely explain urban-rural disparities. In addition, e-cigarettes appear to be rapidly changing traditional patterns of tobacco use, particularly in urban areas. Copyright © 2017 Society for Adolescent Health and Medicine.

    To examine how institutional constraints, comprising federal actions and states' substance abuse policy environments, influence states' decisions to activate Medicaid reimbursement codes for screening and brief intervention for risky substance use in the United States. A discrete-time duration model was used to estimate the effect of institutional constraints on the likelihood of activating the Medicaid reimbursement codes. Primary constraints included federal Screening, Brief Intervention and Referral to Treatment (SBIRT) grant funding, substance abuse priority, economic climate, political climate and interstate diffusion. Study data came from publicly available secondary data sources. Federal SBIRT grant funding did not affect significantly the likelihood of activation (P = 0.628). A $1 increase in per-capita block grant funding was associated with a 10-percentage point reduction in the likelihood of activation (P = 0.003) and a $1 increase in per-capita state substance use disorder expenditures was associated with a 2-percentage point increase in the likelihood of activation (P = 0.004). States with enacted parity laws (P = 0.016) and a Democratic-controlled state government were also more likely to activate the codes. In the United States, the determinants of state activation of Medicaid Screening, Brief Intervention and Referral to Treatment (SBIRT) reimbursement codes are complex, and include more than financial considerations. Federal block grant funding is a strong disincentive to activating the SBIRT reimbursement codes, while more direct federal SBIRT grant funding has no detectable effects. © 2017 Society for the Study of Addiction.

Consequently, this has an impact on market access, trade, food supply, reduced income, increased food prices, decreased farm income and employment. Natural disasters create poverty, which in turn increases the prevalence of food insecurity and malnutrition. It is clear that disasters put food security at risk. The poorest people in the community are affected by food insecurity and disasters; hence, there is a need to be prepared as well as be in a position to manage disasters. Without serious efforts to address them, the risks of disasters will become an increasingly serious obstacle to sustainable development and the achievement of sustainable development goals, particularly goal number 2 ‘end hunger, achieve food security and improved nutrition and promote sustainable agriculture’. In recent years, countries in southern Africa have experienced an increase in the frequency, magnitude and impact of climate change–related hazards such as droughts, veld fire, depleting water resources and flood events. This research aims to reveal Southern African Development Community disaster risk management strategies for food security to see how they an influence and shape policy at the national level in southern Africa. Sustainable Livelihood approach was adopted as the main theoretical framework for the study. The qualitative Analysis is based largely on data from databases such as national reports, regional reports and empirical findings on the disaster management–sustainable development nexus.

  10. Influence of Nitrided Layer on The Properties of Carbon Coatings Produced on X105CrMo17 Steel Under DC Glow-Discharge Conditions

    Full Text Available In most cases, machine components, which come in contact with each other, are made of steel. Common steel types include 100Cr6 and X105CrMo17 are widely used in rolling bearings, which are subjected to high static loads. However, more and more sophisticated structural applications require increasingly better performance from steel. The most popular methods for improving the properties of steel is carburisation or nitriding. Unfortunately, when very high surface properties of steel are required, this treatment may be insufficient. Improvement of tribological properties can be achieved by increasing the hardness of the surface, reducing roughness or reducing the coefficient of friction. The formation of composite layers on steel, consisting of a hard nitride diffusion layer and an external carbon coating with a low coefficient of friction, seems to be a prospect with significant potential. The article describes composite layers produced on X105CrMo17 steel and defines their morphology, surface roughness and their functional properties such as: resistance to friction-induced wear, coefficient of friction and corrosion resistance. The layers have been formed at a temperature of 370°C in successive processes of: nitriding in low-temperature plasma followed by deposition of a carbon coating under DC glow-discharge conditions. An evaluation was also made of the impact of the nitrided layers on the properties and morphology of the carbon coatings formed by comparing them to coatings formed on non-nitrided X105CrMo17 steel substrates. A study of the surface topography, adhesion, resistance to friction-induced wear and corrosion shows the significant importance of the substrate type the carbon coatings are formed on.DOI: http://dx.doi.org/10.5755/j01.ms.22.3.7532

    The World Health Organization (WHO) Framework Convention on Tobacco Control (FCTC) stands to significantly reduce tobacco-related mortality by accelerating the introduction of evidence-based tobacco control measures. However, the extent to which States Parties have implemented the Convention varies considerably. Article 5.3 of the FCTC, is intended to insulate policy-making from the tobacco industry's political influence, and aims to address barriers to strong implementation of the Convention associated with tobacco industry political activity. This paper quantitatively assesses implementation of Article 5.3's Guidelines for Implementation, evaluates the strength of Parties' efforts to implement specific recommendations, and explores how different approaches to implementation expose the policy process to continuing industry influence. We cross-referenced a broad range of documentary data (including FCTC Party reports and World Bank data on the governance of conflicts of interest in public administration) against Article 5.3 implementation guidelines (n = 24) for 155 Parties, and performed an in-depth thematic analysis to examine the strength of implementation for specific recommendations. Across all Parties, 16% of guideline recommendations reviewed have been implemented. Eighty-three percent of Parties that have taken some action under Article 5.3 have introduced less than a third of the guidelines. Most compliance with the guidelines is achieved through pre-existing policy instruments introduced independently of the FCTC, which rarely cover all relevant policy actors and fall short of the guideline recommendations. Measures introduced in response to the FCTC are typically restricted to health ministries and not explicit about third parties acting on behalf of the industry. Parties systematically overlook recommendations that facilitate industry monitoring. Highly selective and incomplete implementation of specific guideline recommendations facilitates

    To investigate researchers' perceptions about the factors that influenced the policy and practice impacts (or lack of impact) of one of their own funded intervention research studies. Mixed method, cross-sectional study. Intervention research conducted in Australia and funded by Australia's National Health and Medical Research Council between 2003 and 2007. The chief investigators from 50 funded intervention research studies were interviewed to determine if their study had achieved policy and practice impacts, how and why these impacts had (or had not) occurred and the approach to dissemination they had employed. We found that statistically significant intervention effects and publication of results influenced whether there were policy and practice impacts, along with factors related to the nature of the intervention itself, the researchers' experience and connections, their dissemination and translation efforts, and the postresearch context. This study indicates that sophisticated approaches to intervention development, dissemination actions and translational efforts are actually widespread among experienced researches, and can achieve policy and practice impacts. However, it was the links between the intervention results, further dissemination actions by researchers and a variety of postresearch contextual factors that ultimately determined whether a study had policy and practice impacts. Given the complicated interplay between the various factors, there appears to be no simple formula for determining which intervention studies should be funded in order to achieve optimal policy and practice impacts.

    Laser modeling activity is described which involved addition of an option allowing N2 as a second diatomic gas. This option is now operational and a few test cases involving N2/CO mixtures were run. Results from these initial test cases are summarized. In the laboratory, a CW double-discharge test facility was constructed and tested. Features include: water-cooled removable electrodes, O-ring construction to facilitate cleaning and design modifications, increased discharge length, and addition of a post-discharge observation section. Preliminary tests with this facility using N2 yielded higher power loadings than obtained in the first-generation facility. Another test-section modification, recently made and as yet untested, will permit injection of secondary gases into the cathode boundary layer. The objective will be to vary and enhance the UV emission spectrum from the auxiliary discharge, thereby influencing the level of photoionization in the main discharge region.

    Highlights: • Identification of organic phase change materials namely benzamide and sebacic acid. • Thermal reliability studies on identified phase change materials. • Measurement of phase transition temperature and latent heat of fusion. • Analysis of relative percentage difference (RPD%) in heat of fusion and melting temperature of benzamide and sebacic acid. - Abstract: Integration of appropriate thermal energy storage system plays a predominant role in upgrading the efficiency of solar thermal energy devices by reducing the incongruity between energy supply and demand. Latent heat thermal energy storage based on phase change materials (PCM) is found to be the most efficient and prospective method for storage of solar thermal energy. Ensuring the thermal reliability of PCM through large number of charging (melting) and discharging (solidification) cycles is a primary prerequisite to determine the suitability of PCM for a specific thermal energy storage applications. The present study explains the experimental analysis carried out on two PCM’s namely benzamide and sebacic acid to check the compatibility of the material in solar thermal energy storage applications. The selected materials were subjected to one thousand accelerated melting and solidification cycles in order to investigate the percentage of variation at different stages on latent heat of fusion, phase transition temperature, onset and peak melting temperature. Differential Scanning Calorimeter (DSC) was used to determine the phase transition temperature and heat of fusion upon completion of every 100 thermal cycles and continued up to 1000 cycles. Relative Percentage Difference (RPD%) is calculated to find out the absolute deviation of melting temperature and latent heat of fusion with respect to zeroth cycle. The experimental study recorded a melting temperatures of benzamide and sebacic acid as 125.09 °C and 135.92 °C with latent heat of fusion of 285.1 (J/g) and 374.4 (J/g). The

    This study presents the results of the accumulation of "2"1"0Po and "2"1"0Pb in fish tissues and organs in a brackish-water marshland that is characterized by high concentrations of "2"2"2Rn and "2"2"6Ra supplied by submarine groundwater discharge (SGD). Tissues and organs from Cyprinus carpio, Chelon labrosus and Carassius auratus in the wetland were significantly enriched by both "2"1"0Pb and "2"1"0Po (up to 55 and 66 times, respectively) compared to blanks. The major input route of "2"1"0Pb and "2"1"0Po into the fish body seems to be through ingestion, due to the high levels of "2"1"0Pb and "2"1"0Po found in the gut content as well as in organs involved in digestion and metabolism (i.e. gut, kidney and hepatopancreas). Results showed that "2"1"0Po was more accumulated in all fish tissues and organs except for the spine, which showed a higher affinity for "2"1"0Pb, due to its capacity to replace Ca from apatite in bones. Over all the variables analyzed, fish tissues/organs and, secondarily, fish species were the most important factors explaining the concentration of radionuclides, whereas fish length and the sampling location played a minor role. The relationship of the two radionuclides varied markedly among tissues and their concentration levels were only correlated in gills, gut and, marginally, in spines. In general, the highest values of "2"1"0Pb and "2"1"0Po concentrations in tissues were found on C. labrosus tissues rather C. auratus and C. carpio. This study demonstrates that inputs of natural radionuclides supplied by SGD to coastal semi-enclosed areas (such as marshlands, lagoons or ponds) may significantly increase the contents of "2"1"0Pb and "2"1"0Po in fish tissues/organs. Thus, this study represents one of the first evidences of direct ecological effects derived from SGD. - Highlights: • Fish tissues showed high concentrations of "2"1"0Pb and "2"1"0Po. • Ingestion pointed to be the major input route of "2"1"0Pb and "2"1"0Po into the fish.

  17. Analyzing the influence of institutions on health policy development in Uganda: a case study of the decision to abolish user fees.

    During the 2001 election campaign, President Yoweri Museveni announced he was abolishing user fees for health services in Uganda. No analysis has been carried out to explain how he was able to initiate such an important policy decision without encountering any immediate barriers. To explain this outcome through in-depth policy analysis driven by the application of key analytical frameworks. An explanatory case study informed by analytical frameworks from the institutionalism literature was undertaken. Multiple data sources were used including: academic literature, key government documents, grey literature, and a variety of print media. According to the analytical frameworks employed, several formal institutional constraints existed that would have reduced the prospects for the abolition of user fees. However, prevalent informal institutions such as "Big Man" presidentialism and clientelism that were both 'competing' and 'complementary' can be used to explain the policy outcome. The analysis suggests that these factors trumped the impact of more formal institutional structures in the Ugandan context. Consideration should be given to the interactions between formal and informal institutions in the analysis of health policy processes in Uganda, as they provide a more nuanced understanding of how each set of factors influence policy outcomes.

    Full text : Partial discharges are a sensitive measure of local electrical stress and therefore the measurements is very often used as a quality check of the insulation. The inception of partial discharges gives information on the limit of the electrical strength of the insulating material before a complete discharge between the conductors takes place. Therefore the insulating material can be tested with high stress but without damaging or reducing the performance of the insulation. Also, for partial discharge measurements it should be taken into account that every stress of the insulation will have an influence on the life expectancy of the material, but a reasonable compromise between the stress during the measurement in order to get reliable results and the influence of he lifetime should be found and established in the relevant standard for the particular equipment, for example transformers, cables and so on

    The problem area of communication between hospital and general practitioners may potentially be improved by the advent of new information technology. The introduction of a regional computer database for general surgery allows the rapid automated production of discharge summaries and has provided us with the opportunity for auditing the quality of old and new styles of discharge communication. A total of 118 general practitioners were sent a postal questionnaire to establish their views on the relative importance of various aspects of patient information and management after discharge. A high response rate (97%) indicated the interest of general practitioners in this topic. The majority (73%) believed that summaries should be delayed no more than 3 days. The structured and shortened new format was preferred to the older style of discharge summary. The older format rarely arrived within an appropriate time and its content was often felt to be either inadequate (35%) or excessive (7%) compared with the new format (8% and 1%, respectively). The diagnosis, information given to the patient, clinic date, list of medications and investigations were considered the more important details in the summary. Improvements in the discharge information were suggested and have subsequently been incorporated in our discharge policy. The use of new information technology, intended to facilitate clinical audit, has improved our ability to generate prompt, well-structured discharge summaries which are accepted by the general practitioners.

    Amanda Yumi Otsuka

    Full Text Available Abstract This study was undertaken in the coastal zone of the state of Pernambuco adjacent to the Recife port area, which corresponds to the inner shelf. This research aimed to analyze the dynamics of chlorophyll-a and several other environmental variables. Sampling was undertaken bimonthly on the surface from September 11th to May 10th, thus including the rainy and dry periods, and during low tide in spring tide. The parameters analyzed were chlorophyll-a, salinity, temperature, transparency, dissolved oxygen, oxygen saturation rate, pH, suspended solids, dissolved inorganic nutrients. Phytoplankton biomass ranged from 13.48 to 145.09 mg m-3 in the estuarine area and on the inner shelf, the variation being from 0.24 to 19.29 mg m-3 in the dry season and from 0.78 to 5.20 mg m-3 in the rainy season. PCA showed a direct relationship of chlorophyll-a with ammonia, phosphate and transparency and an inverse relationship with suspended particulate matter and nitrate. Biomass did not vary significantly different as a result of seasonal or spatial dynamics. The estuary of the Capibaribe River is considered highly impacted, and as it forms the Recife port basin, it joins with two more strongly eutrophic water bodies, the Beberibe River and the Pina Basin, leading to an amplification of its influence on the adjacent shelf. In terms of the river plume's dispersion in the Port of Recife, the presence of a dike causes some disturbance in the direction of the current, limiting the plume to the area close to the coast and influences the oceanographic variables on the inner continental shelf.

  4. Policy implications of select student characteristics and their influence on the Florida biology end-of-course assessment

    Bertolotti, Janine Cecelia

    In an attempt to improve student achievement in science in Florida, the Florida Department of Education implemented end-of-course (EOC) assessments in biology during the 2011-2012 academic school year. Although this first administration would only account for 30% of the student's overall final course grade in biology, subsequent administrations would be accompanied by increasing stakes for students, teachers, and schools. Therefore, this study sought to address gaps in empirical evidence as well as discuss how educational policy will potentially impact on teacher evaluation and professional development, student retention and graduation rates, and school accountability indicators. This study explored four variables- reading proficiency, ethnicity, socioeconomic status, and gender- to determine their influence and relationship on biology achievement on the Biology I EOC assessment at a Title 1 school. To do so, the results of the Biology I EOC assessment administered during the Spring 2012 school year was obtained from a small, rural Title 1 high school in North Florida. Additional data regarding each student's qualification for free and reduced-price lunch, FCAT Reading developmental scale scores, FCAT Reading level, grade level, gender, and ethnicity were also collected for the causal-comparative exploratory study. Of the 178 students represented, 48% qualified for free and reduced-price lunch, 54% were female, and 55% scored at FCAT Reading level 3 or higher. Additionally, 59% were White and 37% Black. A combination of descriptive statistics and other statistical procedures such as independent samples one-tailed t-test, one-way ANOVAs, ANCOVAs, multipleregression, and a Pearson r correlation was utilized in the analysis, with a significance level set at 0.05. Results indicate that of all four variables, FCAT Reading proficiency was the sole variable, after adjusting for other variables; that had a significant impact on biology achievement. Students with higher

    In its simplest form, the glow discharge can be established by passing an electric current through gas between two electrodes. The gas and the electrodes are contained in an insulating envelope. In many technological applications, and not only, the plasma devices are often treated like a black box. There is a series of external parameters or control variables which can be adjusted to obtain a desired effect, namely, the operating voltage, gas pressure, gas nature, gas flow rate, magnetic field strength and magnetic field configuration, electric field geometry, interelectrode distance, and cathode characteristics. The discharge current can be controlled by each of the above control variables. The core idea of this work is the following: a lot of information about the phenomena from the discharge volume, at electrodes or at the discharge bounding wall surface, can be obtained knowing how the change of one of the control parameters influences the discharge current. The following regimes were analyzed: dark discharges (background ionization, saturation regime, Townsend regime, corona regime), glow discharge (the normal and abnormal discharge) and arc discharge (glow to arc transition, non-thermal arcs, thermal arcs). It was concluded that the nonlinearity in the shape of the discharge current characteristics as a function of an external control parameter, can be correlated with the elementary processes and the dynamics of different space charge structures generated in plasma devices.

    China's one-child policy (1979-2015) has affected Chinese parenting practices and children's health behaviors and also may have contributed to increased childhood obesity. However, very limited research has investigated the association between one-child policy and childhood obesity. We examined characteristics of single-child families and the influence of one-child policy (indicated by single-child status) on children's weight status and related health behaviors. Data from children aged 6-18years old in the 2011 (n=1580) and 2000 (n=2317) China Health and Nutrition Survey were cross-sectionally analyzed with multilevel models. From 2000 to 2011, the rates about doubled for being a single-child (30.1% to 57.0%) and being overweight or obese (OWB, 6.6% to 16.5%) along with urbanization (27.5% to 37.1%). Single-child families had higher levels of parental education, household income and urban residence than families with ≥ two children (pchildren with siblings, single children were more likely to be OWB; the association became stronger over time (OR=4.5 (1.7-12.4) in 2011 and 1.7 (1.0-2.8) in 2000). Also, single children had less recreational screen time, but similar physical activity levels; however single urban children were more likely to have excess total energy intake (OR=5.70 (1.58-20.60)) than those with siblings. Being single-child is about four times more likely to be overweight/obesity than those having siblings, and the association became stronger over time in China. China's one-child policy might have contributed to its rising childhood obesity rates. Obesity intervention programs may need to account for the influence of the one-child policy in China.

  8. INFLUENCE OF EXTREME DISCHARGE ON RESTORATION WORKS IN MOUNTAIN RIVER – A CASE STUDY OF THE KRZCZONÓWKA RIVER (SOUTHERN POLAND

    Directory of Open Access Journals (Sweden)

    Anna Lenar-Matyas

    2015-06-01

    Full Text Available The research was conducted on the Krzczonówka River channel, one of the gravel-bedded, regulated mountain river in Polish Carpathians. The main morphological and ecological problem of the river was lack of sediment and channel downcutting. The area is currently associated with an on-going project called “the Upper Raba River Spawning Grounds”. Lowering of an existing debris dam on Krzczonówka River is a part of the project. In 2013 twelve artificial riffles have been created by heaping up stones at points within the segment of the river channel below the debris dam. The riffles are to introduce variety to the longitudinal profile of the river and to reduce the river’s slope. Consequently, these are to decrease sediment transport and to prevent further deepening of the river channel. Post-project monitoring of river restoration works is conducted to determine channel changes and development. In May, 2014, extreme flooding occurred, which caused unexpected changes in channel development. This paper describes maintenance work performed in the riverbed of the Krzczonówka River. Observations and calculations concerning changes in conditions of water flow and sediment transport are also presented. The main purpose is to characterize the influence of an extreme flow event on morphology and functioning of the recently restored gravel-bed river.

    In a thermonuclear device, etc. impurities adsorbed to inner walls of a vacuum vessel by glow discharge are released to clean the vacuum vessel for preventing intrusion of the impurities into plasmas. The object of the present invention is to minimize the capacity of a power source equipment for the glow discharge device to the least extent. That is, a stabilization resistance is connected in series between each of a plurality of anodes which are inserted and arranged at the inside of a vacuum vessel as a cathode and a power source respectively. The resistance value R is selected so as to satisfy the relation: R < (Vi - Vm)/Ii, in which Vi: glow discharge starting voltage, Vm: glow discharge keeping voltage, Ii: glow discharge starting current. Accordingly, if a voltage is applied from a power source to a plurality of anodes, scattering of electric discharge between the anodes can be suppressed and the effect of voltage drop during discharge by the stabilization resistance can be eliminated. As a result, it is possible to provide an economically advantageous glow discharge device with the capacity for the power source facility being to the least extent. (K.M.)

    A method and apparatus are given for producing coaxial arc discharges in an evacuated enclosure and within a strong, confining magnetic field. The arcs are maintained at a high potential difference. Electrons will diffuse to the more positive arc from the negative arc, and positive ions will diffuse from the more positive arc to the negative arc. Coaxial arc discharges have the advantage that ions which return to strike the positive arc discharge will lose no energy since they do not strike a solid wall or electrode. Those discharges are useful in confining an ionized plasma between the discharges, and have the advantage of preventing impurities from the walls of the enclosure from entering ihe plasma area because of the arc barrier set up bv the cylindrical outer arc.

  11. UK strategy for radioactive discharges 2001-2020. Consultation document

    International Nuclear Information System (INIS)

    2000-06-01

    This consultation draft of a strategy for radioactive discharges describes how the United Kingdom (UK) will implement the agreements reached at the 1998 Ministerial meeting of the OSPAR Commission, with regard to radioactive substances. It also provides a policy base for future reviews of discharge authorisations by the regulatory bodies and for strategic planning by the nuclear operators. The strategy sets a framework for radioactive discharges from UK installations over the next twenty years. Its aims are: progressive and substantial reductions in radioactive discharges from the UK as a whole and from each of the main sectors responsible for such discharges; progressive reduction of human exposure to ionising radiation resulting from radioactive discharges, so that no member of the general public in the UK will be exposed to a dose of more than 0.02 mSv a year, as a result of authorised radioactive discharges made from 2020 onwards; progressive reductions in concentrations of radionuclides in the marine environment resulting from radioactive discharges, such that by 2020 they add close to zero to historic levels. The scope of the UK strategy encompasses radioactive discharges from nuclear licensed sites, defence activities and other nuclear and non-nuclear sources of radioactive discharges. It covers both liquid and aerial discharges, although it is assumed that in general liquid discharges will have the largest and most measurable effects in the marine environment

    The United Nations Framework Convention on Climate Change (UNFCCC) laid down the cornerstone in the international cooperation to reduce the greenhouse gas (GHG) emissions from fossil fuels combustion. The UNFCCC provided a general framework for global cooperation to mitigate climate change.

    The United Nations Framework Convention on Climate Change (UNFCCC) laid down the cornerstone in the international cooperation to reduce the greenhouse gas (GHG) emissions from fossil fuels combustion. The UNFCCC provided a general framework for global cooperation to mitigate climate change. The Kyoto Protocol to the UNFCCC which formulated binding GHG emissions reduction targets did not result in universal participation. The United States- the major CO{sub 2} emitting country at the time of the adoption of the Kyoto Protocol in 1997 - signed but did not ratify the Protocol.

    This paper uses the concepts of organisational culture and organisational trust to explore the implementation of equity-oriented policies - the Uniform Patient Fee Schedule (UPFS) and Patients' Rights Charter (PRC) - in two South African district hospitals. It contributes to the small literatures on organisational culture and trust in low- and middle-income country health systems, and broader work on health systems' people-centeredness and "software". The research entailed semi-structured interviews (Hospital A n = 115, Hospital B n = 80) with provincial, regional, district and hospital managers, as well as clinical and non-clinical hospital staff, hospital board members, and patients; observations of policy implementation, organisational functioning, staff interactions and patient-provider interactions; and structured surveys operationalising the Competing Values Framework for measuring organisational culture (Hospital A n = 155, Hospital B n = 77) and Organisational Trust Inventory (Hospital A n = 185, Hospital B n = 92) for assessing staff-manager trust. Regarding the UPFS, the hospitals' implementation approaches were similar in that both primarily understood it to be about revenue generation, granting fee exemptions was not a major focus, and considerable activity, facility management support, and provincial support was mobilised behind the UPFS. The hospitals' PRC paths diverged quite significantly, as Hospital A was more explicit in communicating and implementing the PRC, while the policy also enjoyed stronger managerial support in Hospital A than Hospital B. Beneath these experiences lie differences in how people's values, decisions and relationships influence health system functioning and in how the nature of policies, culture, trust and power dynamics can combine to create enabling or disabling micro-level implementation environments. Achieving equity in practice requires managers to take account of "unseen" but important factors such as

  15. The influence of knowledge on the public policy making process: the case of renewable energies in Midi Pyrenees

    Even though energy policy makers were novices when wind power was introduced in the Midi Pyrenees region, the situation had changed when the photovoltaic was implemented. The new challenges policy makers experimented about the wind power and their opponents, the wood energy and the primacy of the wood's industrials, the photovoltaic and the preservation of the agricultural lands, fostered their learning and gradually lead them to change their perception of inherent issues. The coalitions forged between technical experts and policy makers unbind along the progressive empowerment of the formers. Shared between different forms of knowledge, however, the resources needed to implement renewable energies projects cannot be reduced to the technical dimension. Local knowledge and engineering knowledge increasingly compete with expert knowledge. This evolution corresponds to a policy arrangement change. Since the dynamic but also the elements that compose this political system change, a new reality gradually emerges. This whole process will be the main concern of this thesis. We will finally notice that there are some differences between the implementation of these renewable energies among the territories but also among the three forms of renewable energies we analyze. This means that although renewable energy policy are based on interactions between actors' resources, discourse and rules, they also emerge from the action of intermediates actors, and from the characteristic of each territories in which they are implemented.

    Full Text Available An aging population and epidemiological transition involves prolonged terminal illnesses and an increased demand for end-stage support in health services, mainly in hospitals. Changes in health care and government health policies may influence the death locations, making it possible to remain at home or in an institution. The scope of this article is to analyze death locations in the city of Londrina, State of Paraná, from 1996 to 2010, and to verify the influence of population and health policy changes on these statistics. An analysis was conducted into death locations in Londrina in Mortality Information System (SIM considering the main causes and locations of death. There was an increase of 28% in deaths among the population in general, though 48% for the population over 60 years of age. There was an increase of deaths in hospitals, which were responsible for 70% of the occurrences, though death frequencies in others locations did not increase, and deaths in the home remained at about 18%. The locations of death did not change during this period, even with health policies that broadened care in other locations, such as the patient´s home. The predominance of hospital deaths was similar to other Brazilian cities, albeit higher than in other countries.

    To quantify the Head Start (HS) teacher mediating and moderating influence on the effect of a wellness policy intervention. Intervention trial within a larger randomized community trial. HS preschools in Hawaii. Twenty-three HS classrooms located within 2 previously randomized communities. Seven-month multi-component intervention with policy changes to food served and service style, initiatives for employee wellness, classroom activities for preschoolers promoting physical activity (PA) and healthy eating, and training and technical assistance. The Environment and Policy Assessment and Observation (EPAO) classroom scores and teacher questionnaires assessing on knowledge, beliefs, priorities, and misconceptions around child nutrition and changes in personal health behaviors and status were the main outcome measures. Paired t tests and linear regression analysis tested the intervention effects on the classroom and mediating and moderating effects of the teacher variables on the classroom environment. General linear model test showed greater intervention effect on the EPAO score where teachers reported higher than average improvements in their own health status and behaviors (estimate [SE] = -2.47 (0.78), P teacher health status and behaviors included in a multi-component policy intervention aimed at child obesity prevention may produce a greater effect on classroom environments.

    Full Text Available We investigate the performance measurement of the implementing agencies of EU Structural Funds in Hungary. Following the advice of Thiel and Leeuw (2002, we focus on the incentives created by the institutional environment of these agencies. The core of this environment is a double principal-agent relationship between the European Commission (EC, the national government and the Managing Authority. We investigate its institutional features and the resulting organisational incentives for Managing Authorities in Hungary. Relying on programme evaluations, we explore how these incentives actually affected the design and use of performance measurement by Authorities in two policy fields: active labour-market policy and higher education. We find that external incentives to focus on absorption and formal compliance created bias against integrating performance measurement into the policy process and tackling problems of performance risk and non-measurability.

    Full Text Available Impact assessment (IA of all major European Union (EU policies is now mandatory. The form of IA used has been criticised for favouring corporate interests by overemphasising economic impacts and failing to adequately assess health impacts. Our study sought to assess how, why, and in what ways corporations, and particularly the tobacco industry, influenced the EU's approach to IA.In order to identify whether industry played a role in promoting this system of IA within the EU, we analysed internal documents from British American Tobacco (BAT that were disclosed following a series of litigation cases in the United States. We combined this analysis with one of related literature and interviews with key informants. Our analysis demonstrates that from 1995 onwards BAT actively worked with other corporate actors to successfully promote a business-oriented form of IA that favoured large corporations. It appears that BAT favoured this form of IA because it could advance the company's European interests by establishing ground rules for policymaking that would: (i provide an economic framework for evaluating all policy decisions, implicitly prioritising costs to businesses; (ii secure early corporate involvement in policy discussions; (iii bestow the corporate sector with a long-term advantage over other actors by increasing policymakers' dependence on information they supplied; and (iv provide businesses with a persuasive means of challenging potential and existing legislation. The data reveal that an ensuing lobbying campaign, largely driven by BAT, helped secure binding changes to the EU Treaty via the Treaty of Amsterdam that required EU policymakers to minimise legislative burdens on businesses. Efforts subsequently focused on ensuring that these Treaty changes were translated into the application of a business orientated form of IA (cost-benefit analysis [CBA] within EU policymaking procedures. Both the tobacco and chemical industries have since

    This talk is an overview of discharge lamp technology commonly employed in general lighting, with emphasis on issues pertinent to lighting for plant growth. Since the audience is primarily from the plant growth community, and this begins the light source part of the program, we will start with a brief description of the discharge lamps. Challenges of economics and of thermal management make lamp efficiency a prime concern in controlled environment agriculture, so we will emphasize science considerations relating to discharge lamp efficiency. We will then look at the spectra and ratings of some representative lighting products, and conclude with a discussion of technological advances.

    The aim of the study was to obtain a deeper understanding of the experiences of the discharge process among different professionals. An optimal discharge process for hospitalized elderly to other forms of care is of crucial importance, especially since health and medical policies encourages shorter hospital stays and increased healthcare service in outpatient care. Nurses and social workers from inpatient care, outpatient care, municipal care and social services were interviewed. Eight focus-group interviews with a total of 31 persons were conducted. The subsequent analyses followed a phenomenological approach. The findings revealed three themes, Framework, Basic Values and Patient Resources, which influenced the professionals' actions in the discharge process. The overall emerging structure comprised the patient's vulnerability, dependence and exposed situation in the discharge process. In conclusion some factors are of special importance for the co-operation and the actions of professionals involved in the discharge process. Firstly, a distinct and common framework, with conscious and organizationally based values. Secondly the need to take the patient resources into consideration. Together these factors could contribute to secure the patients involvement in the discharge process and to design an optimal, safe and good care. Collaborative approaches among a range of professionals within a variety of organizations are common, especially in the care of the elderly. The role and support of both the organizations and the educational units are decisive factors in this area.

    Full Text Available The authors examine the industrialization process in Russia for more than a hundred years, the duration and quality parameters associated with its institutional features. The authors also focus on the relevance of the chosen theme because of the formation of new industrial policy institutions. The hypothesis of the study is based on identifying a set of basis factors of building effective institutions: system, decentralization mechanism, clustering, given a set of groups of interests of subjects of industrial policy implementation. Institutions of new industrial policy implementation in contemporary Russia are focused on achieving multifaceted tasks on a temporary basis, the level of implementation, the degree of relevance, therefore, the conclusion regarding the effective implementation of the strategy of economic development of modern Russia, which should include the following institutions: government programs, effective transparent public procurement, institutional design through the creation of specialized, diversified institutions of industrial-innovative development. Named structural elements must be systematically subordinated to the interests of macro-, meso- and micro levels of economic system. Special importance must have experience of building the institutional system of the new industrial policy, which gives effective results on the social-economic development.

    2018-03-01

    Full Text Available The importance of a quick response to changes taking place in the labor market, adaptation to them of the staff policy of enterprises is determined by the need to maintain their competitiveness in the labor market. It is reasonable to monitor main trends in the labor market with a view to adapting the staff policy to changes in order to strengthen the competitive position and attract competent specialists. The aim of the article is to identify the main trends in the labor market and estimate their impact on the staff policy of enterprises in Ukraine. It is determined that the decrease in the number of economically active population, reduction in the supply of workplaces and increase in unemployment are characteristics of the Ukrainian modern labor market. At the same time, there observed a disproportionality between the supply of and demand for representatives of different professional categories. It is determined that the high turnover indices negatively characterize the staff policy and demonstrate that employers neither pay due attention to the issues of forming the employees’ engagement, loyalty nor create appropriate conditions for the fulfillment of their labor potential. The revealed tends lead to increased competition among employers in the labor market for competent specialists, which finally stimulates them to use various instruments for enhancing the enterprises’ attractiveness and the formation of a positive employer brand.

    2017-07-01

    The aim of this study was to identify motivators and barriers that paediatricians face when discharging patients from outpatient specialty care. A questionnaire was administered to outpatient care paediatricians in Victoria working in one of five speciality public hospital clinics. Questions focused on how important various motivators and barriers were in respondents' decision to discharge a patient from their clinic. Nearly all (91%, n=74) paediatricians invited to participate provided responses. The factor influencing the greatest proportion of paediatricians in their decision to discharge patients back to primary care was the potential that patients may not receive the required care from a GP. The next most highly rated barrier was that it is too complicated to arrange discharge; rated as a very important influence by one-third of paediatricians (33%, n=24). Improvements to the discharge process may encourage more paediatricians to discharge patients back to their GP, therefore freeing up appointment slots. This in turn could reduce waiting times for paediatric outpatient clinics in Victoria. The concern from paediatricians that patients may not receive the required care from a GP warrants attention and should be further investigated.

    2015-04-16

    Electric discharge utilized for electrosurgery is studied by means of a recently developed method for the diagnostics of small-size atmospheric plasma objects based on Rayleigh scattering of microwaves on the plasma volume. Evolution of the plasma parameters in the near-electrode sheaths and in the positive column is measured and analyzed. It is found that the electrosurgical system produces a glow discharge of alternating current with strongly contracted positive column with current densities reaching 10(3) A/cm(2). The plasma electron density and electrical conductivities in the channel were found be 10(16) cm(-3) and (1-2) Ohm(-1) cm(-1), respectively. The discharge interrupts every instance when the discharge-driving AC voltage crosses zero and re-ignites again every next half-wave at the moment when the instant voltage exceeds the breakdown threshold.
