    Thermal methods such as differential scanning calorimetry (DSC), and elemental analysis (EA) were employed to determine the calorific values of some renewable biofuels either directly or indirectly. The biofuels tested were the common milkweed, dogbane, kudzu, and eucalyptus tree. The purpose of this work was to optimize the experimental conditions for DSC analysis of biofuels, improve the calorific values by adding metal oxides as catalysts, and compare the heat values between DSC and EA analyses

    Full Text Available The calorific value of coal is an important factor for the economic operation of coal-fired power plant. However, calorific value is tremendous difference between the different coal, and even if coal is from the same mine. Restricted by the coal market, most of coal fired power plants can not burn the designed-coal by now in China. The properties of coal as received are changing so frequently that pulverized coal firing is always with the unexpected condition. Therefore, the researches on the prediction of calorific value of coal have a profound significance for the economic operation of power plants. Aiming at the problem of uncertainty of coal calorific value, establish a soft measurement model for calorific value of coal based on projection pursuit principle combined with genetic algorithm to optimize parameters, and support vector machine algorithm. It is shown by an example that the model has a stronger objectivity, effective and feasible for avoiding the disadvantage of the artificially decided weights of feature indexes. The model could provide a good guidance for the calculation of the coal calorific value and optimization operation of coal-fired power plants.

    The olive press cake heat of combustion has been determined in three modalities: without extraction; extracted; extracted and pulped. The experiences were made by an adiabatic bomb calorimeter. The obtained results are referred to an initial temperature of combustion of approximately 298 K and an initial pressure of 3.0 Mpa. The formed acids were titrated in order to apply the necessary corrections. Percentages of humidity were determined, both the equilibrium and hygroscopic, and ashes. Starting from these results the gross calorific value has been calculated. The quantities listed allow measurement of the saving of hydrocarbon fuels obtained, quantized in oil equivalent ton per year (OET/year). 8 references.

    The fuelwood commonly used in the Western Cape of South Africa, namely Acacia cyclops (Rooikrans), Acacia erioloba (Camelthorn), Eucalyptus cladocalyx (Blue gum), Pinus patula (South African pine) and Vitis vinifera (Vine stumps), was evaluated with regards to its calorific value and environmental impact when burned. Properties, such as density, ash content and elemental composition were determined and related to the calorific value. It could be demonstrated that the wood with the highest calorific value does not necessarily constitute the best option as fuelwood, if environmental factors are taken into account. (author)

    Full Text Available The current global energy crisis has generated growing interest in looking for alternatives to traditional fossil fuels, presenting lignocellulosic materials as a promising resource for sustainable energy production. In this paper, the calorific values and chemical composition of the trunks, branches, twigs and leaves of five timber species of the semi-arid land of Mexico (Helietta parvifolia (Gray Benth., Ebenopsis ebano (Berl. Barneby, Acacia berlandieri (Benth., Havardia pallens (Benth. Britton & Rose and Acacia wrightii (Benth. were determined according to international standards. The results highlighted the calorific value ranges of 17.56 to 18.61 MJ kg−1 in trunks, 17.15 to 18.45 MJ kg−1 in branches, 17.29 to 17.92 MJ kg−1 in twigs, and 17.35to 19.36 MJ kg−1 in leaves. The pH presented an acidic trend (3.95–5.64. The content of mineral elements varied in trunks (1.09%–2.29%, branches (0.86%–2.75%, twigs (4.26%–6.76% and leaves (5.77%–11.79%, showing the higher proportion in Ca (57.03%–95.53%, followed by K (0.95%–19.21% and Mg (0.88%–13.47%. The highest amount of extractives was obtained in the methanolic solvent (3.96%–17.03%. The lignin recorded values of 28.78%–35.84% for trunks, 17.14%–31.39% for branches and 20.61%–29.92% for twigs. Lignin showed a moderately strong correlation (r = 0.66 with calorific value, but the best mathematical model was registered with the calorific value depending on the pH and lignin (R2 = 58.86%.

    Full Text Available In Italy arboreal crops, in particular vine and olive, cover a surface area of around 19.6×109 m2 from which about 4.6×109 kg of pruning are cut. These by-products are currently ploughed into the soil or else harvested and burned in open fields. On the other hand such materials would be more useful as an energy source. If these materials are to be used as fuel, it is important to know their calorific value. The calorific value is significantly influenced by the moisture content of wood. This work has evaluated the changes in moisture content and calorific value with time for different harvesting and storage systems of vine and olive pruning. The observed decrease in the moisture content of the vine and olive pruning depended on the storage system utilized, in particular on the product compression ratio and air circulation. Some differences were observed between the results obtained for vine and olive pruning. The time required for these materials to obtain their best energetic performance was identified at 32 weeks from their harvesting. Harvesting with balers and forwarding costs are about 6.21×10-2 €/kg for vine pruning and 4.64×10-2 €/kg for olive pruning. They are very similar to the price currently offered for energy biomass in Italy (5.00×10-2 €/kg. While the cost actually paid to plough pruning into the soil amounts to about 2.50×10-2 €/kg. Therefore the energy chain encourages a cost-and-benefit analysis.

    The calorific value of coal ash is an important indicator to evaluate the coal quality. In the experiment, the effect of spectrum and processing methods such as smoothing, differential processing, multiplicative scatter correction (MSC) and standard normal variate (SNV) in improving the near-infrared diffuse reflection spectrum signal-noise ratio was analyzed first, then partial least squares (PLS) and principal component analysis (PCR) were used to establish the calorific value model of coal ash for the spectrums processed with each preprocessing method respectively. It was found that the model performance can be obviously improved with 5-point smoothing processing, MSC and SNV, in which 5-point smoothing processing has the best effect, the coefficient of association, correction standard deviation and forecast standard deviation are respectively 0.9899, 0.00049 and 0.00052, and when 25-point smoothing processing is adopted, over-smoothing occurs, which worsens the model performance, while the model established with the spectrum after differential preprocessing has no obvious change and the influence on the model is not large.

    A total of 220 faecal pig and poultry samples, collected from different experimental trials were employed with the aim to demonstrate the suitability of Near Infrared Reflectance Spectroscopy (NIRS) technology for estimation of gross calorific value on faeces as output products in energy balances studies. NIR spectra from dried and grounded faeces samples were analyzed using a Foss NIRSystem 6500 instrument, scanning over the wavelength range 400-2500 nm. Validation studies for quantitative analytical models were carried out to estimate the relevance of method performance associated to reference values to obtain an appropriate, accuracy and precision. The results for prediction of gross calorific value (GCV) of NIRS calibrations obtained for individual species showed high correlation coefficients comparing chemical analysis and NIRS predictions, ranged from 0.92 to 0.97 for poultry and pig. For external validation, the ratio between the standard error of cross validation (SECV) and the standard error of prediction (SEP) varied between 0.73 and 0.86 for poultry and pig respectively, indicating a sufficiently precision of calibrations. In addition a global model to estimate GCV in both species was developed and externally validated. It showed correlation coefficients of 0.99 for calibration, 0.98 for cross-validation and 0.97 for external validation. Finally, relative uncertainty was calculated for NIRS developed prediction models with the final value when applying individual NIRS species model of 1.3% and 1.5% for NIRS global prediction. This study suggests that NIRS is a suitable and accurate method for the determination of GCV in faeces, decreasing cost, timeless and for convenient handling of unpleasant samples.. (Author)

    The combustion process of pulverized coal injected into blast furnace involves a lot of physical and chemical reactions. Based on the combustion behaviors of pulverized coal, the conception of coal effective calorific value representing the actual thermal energy provided for blast furnace was proposed. A cost performance evaluation model of coal injection was built up for the optimal selection of various kinds of coal based on effective calorific value. The model contains two indicators: coal effective calorific value which has eight sub-indicators and coal injection cost which includes four sub-indicators. In addition, the calculation principle and application of cost performance evaluation model in a Chinese large-scale iron and steel company were comprehensively introduced. The evaluation results finally confirm that this novel model is of great significance to the optimal selection of blast furnace pulverized coal.

    The gross calorific value (GCV), proximate, ultimate and chemical analysis of debark wood in Portugal were studied, for future utilization in wood pellets industry and the results compared with CEN/TS 14961. The relationship between GCV, ultimate and chemical analysis were determined by multiple regression stepwise backward. The treatment between hardwoods-softwoods did not result in significant statistical differences for proximate, ultimate and chemical analysis. Significant statistical differences were found in carbon for National (hardwoods-softwoods) and (National-tropical) hardwoods in volatile matter, fixed carbon, carbon and oxygen and also for chemical analysis in National (hardwoods-softwoods) for F and (National-tropical) hardwoods for Br. GCV was highly positively related to C (0.79 * * *) and negatively to O (-0.71 * * *). The final independent variables of the model were (C, O, S, Zn, Ni, Br) with R(2)=0.86; F=27.68 * * *. The hydrogen did not contribute statistically to the energy content.

    Fossil fuel still dominates the needs of energy in Indonesia for the past few years. The increasing scarcity of oil and gas from non-renewable materials results in an energy crisis. This condition turns to be a serious problem for society which demands immediate solution. One effort which can be taken to overcome this problem is the utilization and processing of biomass as renewable energy by means of carbonization. Thus, it can be used as qualified raw material for production of briquette. In this research, coconut shell is used as carbonized waste. The research aims at improving the quality of coconut shell as the material for making briquettes as cheap and eco-friendly renewable energy. At the end, it is expected to decrease dependence on oil and gas. The research variables are drying temperature and time, carbonization time and temperature. The dependent variable is calorific value of the coconut shell. The method used in this research is Taguchi Method. The result of the research shows thus variables, have a significant contribution on the increase of coconut shell's calorific value. It is proven that the higher thus variables are higher calorific value. Before carbonization, the average calorific value of coconut shell reaches 4,667 call/g, and a significant increase is notable after the carbonization. The optimization is parameter setting of A2B3C3D3, which means that the drying temperature is 105 °C, the drying time is 24 hours, the carbonization temperature is 650 °C and carbonization time is 120 minutes. The average calorific value is approximately 7,744 cal/g. Therefore, the increase of the coconut shell's calorific value after the carbonization is 3,077 cal/g or approximately 60 %. The charcoal of carbonized coconut shell has met the requirement of SNI, thus it can be used as raw material in making briquette which can eventually be used as cheap and environmental friendly fuel.

    The article presents a new method of monitoring calorific value in regional distribution grids. Standard load profiles are combined with a new correction algorithm in order to calculate the decrease volume in the connecting points of the grid. This way, a calorific value can be calculated for each grid node that is based on combustion values from calibrate measurements in the connection points, and customers can be billed efficiently in supply districts with several natural gas and/or biogas feed-in stations. Cost-intensive conditioning of biogas can be prevented, so that biogas plants will achieve higher economic efficiency. Further, the results of a field test for validation of the process are presented. In a H-gas regional grid of E.ON Avacon, calorific value was measured in different points for a period of nine months, using a mobile process gas chromatograph. Two different types of gas are supplied to the grid, i.e. H-grade natural gas and biogas. The deviations between measured and calculated calorific values was in the range of 0.05 percent as referred to the monthly average. The article also presents a new manner of representation of the results.

    The experimental determination of higher heating value (HHV) of solid fuels is a cost intensive process, as it requires special instrumentation and highly trained analyst to operate it, where as proximate analysis data can be obtained relatively easily using an ordinary muffle furnace. Therefore, to simplify the task and to reduce the cost of analysis many correlations were developed for determining HHV from proximate analysis of solid fuels. An attempt has been made in this paper to evaluate the applicability of these correlations with a special focus on Indian coals. It has been observed that the developed correlations are either complex in nature or by-pass the effect of important variables like moisture and ash contents of coals. An effort has, therefore, been made to develop a simple correlation based on proximate analysis data for predicting HHV of coal (as-received basis). The model presented here is developed using analyses of 250 coal samples and its significance lies in involvement of all the major variables affecting the HHV. The developed model appears to be better than the existing models. 10 refs., 4 figs., 2 tabs.

    Biomass wastes produced from oil palm mills and plantations include empty fruit bunches (EFBs), shells, fibers, trunks, and oil palm fronds (OPF). EFBs and shells are partially utilized as boiler fuel while the rest of the biomass materials like OPF have not been utilized for energy generation. No previous study has been reported on gasification of oil palm fronds (OPF) biomass for the production of fuel gas. In this paper, the effect of moisture content of fuel and reactor temperature on downdraft gasification of OPF was experimentally investigated using a lab scale gasifier of capacity 50 kW. In addition, results obtained from equilibrium model of gasification that was developed for facilitating the prediction of syngas composition are compared with experimental data. Comparison of simulation results for predicting calorific value of syngas with the experimental results showed a satisfactory agreement with a mean error of 0.1 MJ/Nm3. For a biomass moisture content of 29%, the resulting calorific value for the syngas was found to be only 2.63 MJ/Nm3, as compared to nearly double (4.95 MJ/Nm3) for biomass moisture content of 22%. A calorific value as high as 5.57 MJ/Nm3 was recorded for higher oxidation zone temperature values. PMID:24578617

    The biodiesel fuel is a renewable source of alternative fuel used in diesel cycle engines. The production of biodiesel involves the reaction of methanol with fatty acids of animal or vegetable. The production of biodiesel from chicken fat can be very attractive for some regions from Brazil with high poultry production, as in the Parana West and Santa Catarina West. In this study , the goal was the lower calorific value of the compositions between biodiesel and diesel oil: 100% Diesel oil (B0), 20% biodiesel (B20), 40% biodiesel (B40), 60% biodiesel (B60), 80% biodiesel (B80 ), 100% biodiesel (B100). The biodiesel used was acquired in the Centre for Development and Diffusion of technologies on the Assis Gurgacz College, in Cascavel city. The nominal production capacity of the unit is 900 liters on period of 8 hours. The model of the calorimeter used, was the E2K. The lower calorific value of B100 composition was 35.388 MJ kg-1 and the diesel oil was 41.299 MJ kg-1. With the measuring of the caloric value of six samples mix of diesel oil and biodiesel, was obtained a linear function decrease of the calorific value when increased it the proportion of biodiesel from chicken fat into fuel.

    Due to legal consequences, measures for waste treatment have to be classified as measures for utilization or for removal. In principle, the actual equations for calculation exhibit errors. Therefore, these equations are not suitable for the distinction between utilization and removal of waste. The authors of the contribution under consideration report on the fundamental method for balancing usually applied in process engineering. As extension, the utilization of equivalence values in the evaluation of different kinds of energy and in the calculation of calorific values of wastes is discussed. At first, the thermodynamic significance and utilization of equivalence values are described using simple examples. It is shown that equivalence values are used which do not agree with the fundamentals of thermodynamics. Regarding to the calorific value, the authors also describe fundamental approaches. A qualitative and quantitative discussion is performed according to regression formulas of calorific values.

    Bio-fuel produced from renewable sources is considered the most viable alternatives for the replacement of mineral diesel fuel in compression ignition engines. There are several options for biomass derived fuels production involving chemical, biological and thermochemical processes. One of the best options is Fischer Tropsch Synthesis, which has an extensive history of gasoline and diesel production from coal and natural gas. FTS fuel could be one of the best solutions to the fuel emission due to its high quality. FTS experiments were carried out in 16 different operation conditions. Mini structured vertical downdraft fixed bed reactor was used for the FTS. Instead of Biomass gasification, a simulated N2 -rich syngas cylinder of, 33% H2 and 50% N2 was used. FT fuels products were analyzed in GCMS to find the hydrocarbon distributions of FT fuel. Calorific value and lubricity of liquid FT product were measured and compared with commercial diesel fuel. Lubricity has become an important quality, particularly for biodiesel, due to higher pressures in new diesel fuel injection (DFI) technology which demands better lubrication from the fuel and calorific value which is amount of energy released in combustion paly very important role in CI engines. Results show that prepared FT fuel has desirable properties and it complies with standard values. FT samples lubricities as measured by ASTM D6079 standard vary from 286μm (HFRR scar diameter) to 417μm which are less than limit of 520μm. Net Calorific value for FT fuels vary from 9.89 MJ/kg to 43.29 MJ/kg, with six of the samples less than EN 14213 limit of 35MJ/kg. Effect of reaction condition on FT fuel properties was investigated which illustrates that in higher pressure Fischer-Tropsch reaction condition liquid product has better properties.

Gross calorific value of the wood was determined for a random sample of trees in each test: gross CV and CVm{sup 3} = gross calorific value in MJ kg{sup -1} and MJ m{sup -3}, respectively. The major objectives were to determine if gross CV was positively correlated with wood density and tree growth, and if gross CV and/or CVm{sup 3} varied with rainfall gradients in the sample region. Provenances were grouped into a drier and more humid zone, and correlations were computed among all trees and separately in each zone. Results indicated that gross CV was not significantly correlated with density in either species. Gross CV was positively correlated with growth of P. africana (but not B. aegyptiaca) only in the drier zone. Gross CVm{sup 3} was positively correlated with growth of both species, and the correlations were stronger in the drier zone. Multiple regressions with provenance latitude, longitude and elevation indicated that provenance means for gross CV increased, in general, from the drier to the more humid zones. Regressions with gross CVm{sup 3} were not significant. Results are compared with earlier research reports from the provenance/progeny tests and with other tropical hardwood species; and practical implications are presented for tree improvement and conservation programs in the region.

    Calculating the calorific value signal on line is the supporting Tor the optimization of boiler control and combustion. Based on the energy balance and chemical mass balance, the soft measurement of calorific value was researched, and was implemented in a 600 MW thermal power unit. The calculation results show that the energy balance method has higher static precision and worse dynamic characteristics, and the chemical mass balance method has teller dynamic characteristics and lower static precision. So an improvement of information fusion technology was proposed.

In the present study, visible and near-infrared (Vis-NIR) spectroscopy was employed to build prediction models of componential contents, i. e. moisture, ash, volatile matter and fixed-carbon, and calorific value of three selected species of agricultural biomass feedstock, i. e. pine wood,cedar wood, and cotton stalk. The partial least squares (PLS) cross validation results showed that compared with original reflection spectra, PLS regression models developed for first derivative spectra produced higher prediction accuracy with coefficients of determination (R2) of 0. 97, 0. 94 and 0. 90, and residual prediction deviation (RPD) of 6. 57, 4. 00 and 3. 01 for ash, volatile matter and moisture, respectively. Good prediction accuracy was achieved with R2 of 0. 85 and RPD of 2. 55 for fixed carbon, and R2 of 0. 87 and RPD of 2. 73 for calorific value. It is concluded that the Vis-NIR spectroscopy is promising as an alternative of traditional proximate analysis for rapid determination of componential contents and calorific value of agricultural biomass feedstock.

    Gross calorific value ( GCV) has been introduced to biological research and applied to reflect the capability of plant species to fix solar radiation. Calorific value has also been considered as a coefficient characteristic to evaluate the adaptation strategies of plant species to the external environment. Therefore, understanding the variation in GCV among different ecosystems may provide a basis for assessing energy fixation, transformation, and utilization efficiency. A number of studies have indicated that GCV varies among different geographical locations and ecological categories. Some studies have suggested that the energy contents of alpine plants should be higher than those of tropical plants, and have also shown that energy content differs among different plant life forms, decreasing in the sequence tree >shrub >herb. However, little has been reported on the patterns of GCV in different typical ecosystems ( at the levels of species, life form, and community) across multiple zones. In this study, we compared the leaf calorific values of plant species in two forest ecosystem-subtropical evergreen broad-leaved and warm temperate deciduous broad-leaved forests in China. Field sampling was carried out in early August 2013 at Jiulian Mountain ( Jiangxi Province) and Dongling Mountain ( Beijing Province) , China. Leaf samples of 276 plant species were collected from subtropical evergreen broad-leaved and warm temperate deciduous broad-leaved forests, and the calorific values of these leaves were measured using a PARR 1281 oxygen bomb calorimeter. To explore the variability in GCV, we analyzed the data at the levels of species, life form ( trees, shrubs, and herbs) , and community in the two forest types. Furthermore, trees were subdivided into evergreen and deciduous, and coniferous and broad-leaved. The results showed that the GCV of the subtropical evergreen broad-leaved forest was 17. 83 kJ/g ( n=191) , whereas that of the warm temperate deciduous broad

    after sugarcane stalks are crushed to extract their juice, is the primary fuel source for steam generation to supply for all the needs of a typical sugar mill in Tucumán, Argentina. In factories equipped to separate bagasse from pith to supply fibre for paper producing plants, pith and its blends with bagasse at different proportions are also available as fuels. The value of bagasse as a fuel depends on a number of ecological, agronomic and industrial factors, and it affects steam generation efficiency. The aim of this report is to assess the value of bagasse as a fuel in sugar mills in Tucumán. A total of 419 bagasse samples, collected from different sugar mills in Tucumán, were processed and tested with a bomb calorimeter to measure their higher calorific value (PCS and its correlation with ash contents. In order to identify the relationship between ash content in bagasse and its ignition delay, PCS was calculated one minute after ignition. Bagasse PCS from three widely used sugarcane varieties was also determined. Results showed that 17375 kJ/kg is eligible as a mean higher calorific value for bagasse from sugar mills in Tucumán, whereas pith mean higher calorific value can be set at 17.075 kJ/kg. These values should be adjusted according to ash content level. Although variability amongst mean PCS was low, it was possible to identify the relationship between ecosystem and sugarcane development, its final fibre content and, thereby, its calorific value.

    1985-01-01

    Predetermined amounts of heat are generated within a coal sample (11) by directing pump light pulses (14) of predetermined energy content into a small surface region (16) of the sample (11). A beam (18) of probe light is directed along the sample surface (19) and deflection of the probe beam (18) from thermally induced changes of index of refraction in the fluid medium adjacent the heated region (16) are detected. Deflection amplitude and the phase lag of the deflection, relative to the initiating pump light pulse (14), are indicative of the calorific value and the porosity of the sample (11). The method provides rapid, accurate and non-destructive analysis of the heat producing capabilities of coal samples (11). In the preferred form, sequences of pump light pulses (14) of increasing durations are directed into the sample (11) at each of a series of minute regions (16) situated along a raster scan path (21) enabling detailed analysis of variations of thermal properties at different areas of the sample (11) and at different depths.

    To obtain high calorific biogas via anaerobic digestion without additional upgrading equipment, a two-phase pressurized biofilm system was built up, including a conventional continuously stirred tank reactor and a pressurized biofilm anaerobic reactor (PBAR). Four different pressure levels (0.3, 0.6, 1.0 and 1.7MPa) were applied to the PBAR in sequence, with the organic loading rate maintained at 3.1g-COD/L/d. Biogas production, gas composition, process stability parameters were measured. Results showed that with the pressure increasing from 0.3MPa to 1.7MPa, the pH value decreased from 7.22±0.19 to 6.98±0.05, the COD removal decreased from 93.0±0.9% to 79.7±1.2% and the methane content increased from 80.5±1.5% to 90.8±0.8%. Biogas with higher calorific value of 36.2MJ/m(3) was obtained at a pressure of 1.7MPa. Pressure showed a significant effect on biogas production and gas quality in methanogenesis reactor.

    Rotary kiln incinerators and cement kilns are two energy intensive processes, requiring high temperatures that can be obtained by the combustion of fossil fuel. In both processes, fossil fuel is often substituted by high or medium calorific waste to avoid resource depletion and to save costs. Two types of industrial calorific waste streams are considered: automotive shredder residue (ASR) and meat and bone meal (MBM). These waste streams are of current high interest: ASR must be diverted from landfill, while MBM can no longer be used for cattle feeding. The environmental impact of the incineration of these waste streams is assessed and compared for both a rotary kiln and a cement kiln. For this purpose, data from an extensive emission inventory is applied for assessing the environmental impact using two different modeling approaches: one focusing on the impact of the relevant flows to and from the process and its subsystems, the other describing the change of environmental impact in response to these physical flows. Both ways of assessing emphasize different aspects of the considered processes. Attention is paid to assumptions in the methodology that can influence the outcome and conclusions of the assessment. It is concluded that for the incineration of calorific wastes, rotary kilns are generally preferred. Nevertheless, cement kilns show opportunities in improving their environmental impact when substituting their currently used fuels by more clean calorific waste streams, if this improvement is not at the expense of the actual environmental impact.

    2015-05-01

    Full Text Available Corn stover is an abundant agricultural residue that could be used on the farm for heating and crop drying. Ash content and calorific energy of corn grain and six stover components were measured from standing plants during the grain maturing period, between mid-September and mid-November. Ash of stover in standing corn averaged 4.8% in a cool crop heat unit zone (2300–2500 crop heat units (CHU and 7.3% in a warmer zone (2900–3100 CHU. The corn cob had the lowest ash content (average of 2.2% while leaves had the highest content (from 7.7% to 12.6%. In the fall, ash content of mowed and raked stover varied between 5.5% and 11.7%. In the following spring, ash content of stover mowed, raked and baled in May averaged 3.6%. The cob and stalk located below the first ear contained the highest calorific energy with 17.72 MJ·kg−1. Leaves and grain had the lowest energy with an average of 16.99 MJ·kg−1. The stover heat of combustion was estimated at 17.47 MJ·kg−1 in the cool zone and 17.26 MJ·kg−1 in the warm zone. Based on presented results, a partial “cob and husk” harvest system would collect less energy per unit area than total stover harvest (44 vs. 156 GJ·ha−1 and less biomass (2.51 vs. 9.13 t·dry matter (DM·ha−1 but the fuel quality would be considerably higher with a low ash-to-energy ratio (1.45 vs. 4.27 g·MJ−1.

  2. Determination of heating value of industrial waste for the formulation of alternative fuels

    Directory of Open Access Journals (Sweden)

    Bouabid G.

    2013-09-01

    Full Text Available The use of alternative fuels has become increasingly widespread. They are basically designed based on industrial waste so that they can substitute fossil fuels which start to become scarce. Alternative fuels must meet some criteria, namely an important calorific content, minimum humidity and ash content. When it comes to combustion, the most interesting parameter is the calorific value which represents the thermal energy released during combustion. The experiments that were conducted showed that the calorific value is influenced by other parameters namely moisture and ash content. It was therefore necessary to study the behavior of the heating value in terms of these two parameters in order to establish a relationship that is used to describe the behavior. This is expected to allow a simulation of the calorific value of a mixture of various industrial waste.

    The early flame development stage of syngas and CNG are analysed and compared from the flame images taken over 20° CA from the start of ignition. An imitated syngas with a composition of 19.2% H2, 29.6% CO, 5.3% CH4 and balance with nitrogen and carbon dioxide, which resembles the typical product of wood biomass gasification, was used in the study. A CCD camera triggered externally through the signals from the camshaft and crank angle sensors was used in capturing of the images. The engine was accessed through an endoscope access and a self-illumination inside the chamber. The results of the image analysis are further compared with the mass fraction burn curve of both syngas and CNG analysed from the pressure data. The analysis result of the flame image of syngas validates the double rapid burning stage of the mass fraction burn of syngas analysed from in-cylinder pressure data.

    Autogenerative high pressure digestion (AHPD) is a novel configuration of anaerobic digestion, in which micro-organisms produce autogenerated biogas pressures up to 90 bar with >90% CH(4)-content in a single step reactor. (1) The less than 10% CO(2)-content was postulated to be resulting from proportionally more CO(2) dissolution relative to CH(4) at increasing pressure. However, at 90 bar of total pressure Henry's law also predicts dissolution of 81% of produced CH(4). Therefore, in the present research we studied whether CO(2) can be selectively retained in solution at moderately high pressures up to 20 bar, aiming to produce high-calorific biogas with >90% methane. Experiments were performed in an 8 L closed fed-batch pressure digester fed with acetate as the substrate. Experimental results confirmed CH(4) distribution over gas and liquid phase according to Henry's law, but the CO(2)-content of the biogas was only 1-2%, at pH 7, that is, much lower than expected. By varying the ratio between acid neutralizing capacity (ANC) and total inorganic carbon (TIC(produced)) of the substrate between 0 and 1, the biogas CO(2)-content could be controlled independently of pressure. However, by decreasing the ANC relative to the TIC(produced) CO(2) accumulation in the aqueous medium caused acidification to pH 5, but remarkably, acetic acid was still converted into CH(4) at a rate comparable to neutral conditions.

    Full Text Available Abstract Background Accumulation of lifestyle physical activity is a current aim of health promotion, with increased stair climbing one public health target. While the workplace provides an opportunity for regular stair climbing, evidence for effectiveness of point-of-choice interventions is equivocal. This paper reports a new approach to worksite interventions, aimed at changing attitudes and, hence, behaviour. Methods Pre-testing of calorific expenditure messages used structured interviews with members of the public (n = 300. Effects of multi-component campaigns on stair climbing were tested with quasi-experimental, interrupted time-series designs. In one worksite, a main campaign poster outlining the amount of calorific expenditure obtainable from stair climbing and a conventional point-of-choice prompt were used (Poster alone site. In a second worksite, additional messages in the stairwell about calorific expenditure reinforced the main campaign (Poster + Stairwell messages site. The outcome variables were automated observations of stair and lift ascent (28,854 and descent (29,352 at baseline and for three weeks after the intervention was installed. Post-intervention questionnaires for employees at the worksites assessed responses to the campaign (n = 253. Analyses employed Analysis of Variance with follow-up Bonferroni t-tests (message pre-testing, logistic regression of stair ascent and descent (campaign testing, and Bonferroni t-tests and multiple regression (follow-up questionnaire. Results Pre-testing of messages based on calorific expenditure suggested they could motivate stair climbing if believed. The new campaign increased stair climbing, with greater effects at the Poster + Stairwell messages site (OR = 1.52, 95% CI = 1.40-1.66 than Posters alone (OR = 1.24, 95% CI = 1.15-1.34. Follow-up revealed higher agreement with two statements about calorific outcomes of stair climbing in the site where they

    UBC (upgrading brown coal) is a method of improving the quality of coal by using oil as an additive. Through processing in the oil media, not just the calories that increase, but there is also water repellent properties and a decrease in the tendency of spontaneous combustion of coal products produced. The results showed a decrease in the water levels of natural coal bayah reached 69%, increase in calorific value reached 21.2%. Increased caloric value and reduced water content caused by the water molecules on replacing seal the pores of coal by oil and atoms C on the oil that is bound to increase the percentage of coal carbon. As a result of this experiment is, the produced coal has better calorific value, the increasing of this new calorific value up to 23.8% with the additive waste lubricant, and the moisture content reduced up to 69.45%.

    The HOTDISC technology allows the use of Solid Recovered Fuel (SRF) of a coarse grain size in cement rotary kilns. A suitable medium-calorific SRF is produced by mechanical treatment of mixed municipal and commercial waste that was previously used in fluidized bed incineration systems. Through a modification of the production process the quality of the SRF could be improved and its energetic utilization within a cement kiln with an integrated HOTDISC technology was realized. In course of a material flow analysis changes in quality and mass due to planned process changes were simulated on a theoretical basis. Due to a good agreement of the mass and quality prediction with the real data of the material flow analysis conducted after the system implementation it can be stated that by simulation beforehand the security in planning increases while the economic risk can be significantly reduced. Both the material flow analysis as well as practical operational experience confirms that the industrially produced HOTDISC SRF is applicable and can be produced from mixed municipal and commercial solid waste. An improvement in quality of the produced HOTDISC SRF can be shown by positive changes of essential parameters. From a waste management perspective the production and energetic utilization of HOTDISC SRF is reasonable by all means. This is shown by the conduction of an energy and CO₂-balance. A growing international importance of the HOTDISC technology and the increased use of medium-calorific SRF are expected.

    The aim of the project was to get higher automatization level and improve dust preventing in solid fuel receiving stations. There are two general types of receiving stations in the Finnish power plants: large unloading stations for the side tipping devices of trucks and small ones for the rear tipping devices of trucks. In the first ones the trucks empty their load (approx. 100 m{sup 3} loose bulk density) divided by hauling unit and trailer within few (5-10) minutes into a rectangular box, which depth is approx. 3 m. The discharging causes a strong counter current air and dust flow (20-40 m{sup 3}/s) upwards and the dust will easily spread out all over the station. In the second ones the discharging takes place from the rear of truck and trailer using loadspace conveyor of the vehicle within 20 minutes. The material falls on a (belt) conveyor, which is on the floor level. The problems in side tipping system are connected with dust and surplus time, which is needed for the preparation and completion of unloading and sampling. For the fine dust control has also been tested water spray (fog) nozzles and tried to utilise a settling chamber for the dust stream. Also the using the settling chamber equipped with air suction connections and cyclone separation may be effective. In the rear tipping system are also applied bag filters because of smaller air quantities. The rapid truck positioning and control in the receiving station is one of the presupposition for the fast and accurate unloading. This can be done using ultrasonic sensing methods. Also the ensuring of accurate discharging can be based on the modern technology. One of the basic things is the enlarging of video control (CCD -cameras)

    Seed oils have proved recalcitrant to modification for the production of industrially useful lipids. Here, we demonstrate the successful metabolic engineering and subsequent field production of an oilseed crop with the highest accumulation of unusual oil achieved so far in transgenic plants. Previously, expression of the Euonymus alatus diacylglycerol acetyltransferase (EaDAcT) gene in wild-type Arabidopsis seeds resulted in the accumulation of 45 mol% of unusual 3-acetyl-1,2-diacyl-sn-glycerols (acetyl-TAGs) in the seed oil (Durrett et al., 2010 PNAS 107:9464). Expression of EaDAcT in dgat1 mutants compromised in their ability to synthesize regular triacylglycerols increased acetyl-TAGs to 65 mol%. Camelina and soybean transformed with the EaDAcT gene accumulate acetyl-triacylglycerols (acetyl-TAGs) at up to 70 mol% of seed oil. A similar strategy of coexpression of EaDAcT together with RNAi suppression of DGAT1 increased acetyl-TAG levels to up to 85 mol% in field-grown transgenic Camelina. Additionally, total moles of triacylglycerol (TAG) per seed increased 20%. Analysis of the acetyl-TAG fraction revealed a twofold reduction in very long chain fatty acids (VLCFA), consistent with their displacement from the sn-3 position by acetate. Seed germination remained high, and seedlings were able to metabolize the stored acetyl-TAGs as rapidly as regular triacylglycerols. Viscosity, freezing point and caloric content of the Camelina acetyl-TAG oils were reduced, enabling use of this oil in several nonfood and food applications.

    Solid recovered fuels constitute a valuable alternative for the management of those non-hazardous waste fractions that cannot be recycled. The main purpose of this research is to assess the suitability of three different wastes from the landfill of the local waste management company (COGERSA), to be used as solid recovered fuels in a cement kiln near their facilities. The wastes analyzed were: End of life vehicles waste, packaging and bulky wastes. The study was carried out in two different periods of the year: November 2013 and April 2014. In order to characterize and classify these wastes as solid recovered fuels, they were separated into homogeneous fractions in order to determine different element components, such as plastics, cellulosic materials, packagings or textile compounds, and the elemental analysis (including chlorine content), heavy metal content and the heating value of each fraction were determined. The lower heating value of the waste fractions on wet basis varies between 10 MJ kg(-1) and 42 MJ kg(-1). One of the packaging wastes presents a very high chlorine content (6.3 wt.%) due to the presence of polyvinylchloride from pipe fragments, being the other wastes below the established limits. Most of the wastes analyzed meet the heavy metals restrictions, except the fine fraction of the end of life vehicles waste. In addition, none of the wastes exceed the mercury limit content, which is one of the parameters considered for the solid recovered fuels classification. A comparison among the experimental higher heating values and empirical models that predict the heating value from the elemental analysis data was carried out. Finally, from the three wastes measured, the fine fraction of the end of life vehicles waste was discarded for its use as solid recovered fuels due to the lower heating value and its high heavy metals content. From the point of view of the heating value, the end of life vehicles waste was the most suitable residue with a lower

    THE truth seems to be that the common edible fats, whether of animal or vegetable origin, have no constant vitamin value. Some are usually low or lacking in vitaminic activity, and the best are variable in this respect. Until some criterion other than taste, appearance, or reputation can be devised for judging the nutritional value of fats as purchased, we must assume them to be unreliable sources of vitamins and dependable only for their universally high calorific value.

    The widespread utilization of fertilizers from petroleum on agroecosystems implicates in high energy consumption. The utilization of organic residues might be an alternative to petroleum byproducts. Thus the objective of this study was estimate the caloric power of the sewage sludge from Barueri ETE. The caloric power was measured by using the calorimeter method. For the calculation, the formula of determination of the caloric power was applied and calculated by the arithmetical average of seven repetitions. The rate 4.1855 was adopted in conversion calorie/Joule. One tonne from sewage sludge presented: N{sub 2}) 1902.82 MJ t{sup -1}; P{sub 2}O{sub 5}) 380.29 MJ t{sup -1}and K{sub 2}O) 144.06 MJ t{sup -1}; the total was: 2427,17 MJ t{sup -1}. The mean value of the caloric power for sewage sludge is 5078,18 kcal kg{sup -1} (21,25 MJ kg{sup -1}). The sewage sludge can be an alternative option regarding energy economy in the way for reduction of petroleum dependence. (author)

    An experimental system with regenerative sections at both ends was conducted to analyze the combustion characteristics of low calorific premixed gases (equivalence ratio<0. 4)in a reciprocal flow porous media combustor. Temperature fluctuation, axial temperature distribution and flammability limits were investigated. Results show that the flame position directly influences the temperature fluctuation of exhaust gases; Adding regenerative sections leads to the reduction of temperature fluctuation amplitude in ceramic foam; the shape of axial temperature distribution has continuous changes, from saddle-shaped, ladder-shaped, oval-shaped to triangle-shaped when the system reaches flammability limit as the equivalence ratio decreases. The average temperature of high temperature zone rises and the temperature of exhaust gases falls by adding the regenerative sections. The flammability limit is closely related to half-period, inlet velocity and heat load. The flammability limit can be extended to the low equivalence ratio of 0.1.%为了研究低热值预混燃气(当量比<0.4)在往复式多孔介质燃烧器中的燃烧特性,建立两端布置蓄热段的往复多孔介质燃烧试验台,研究温度波动、轴向温度分布及燃烧极限的特性.结果表明,低热值预混燃气温度波动特性与火焰面位置有直接关系,两端布置蓄热段能够减小泡沫陶瓷多孔介质温度波动幅度.随着当量比的降低,轴向温度分布形状从“马鞍形”、“梯形”、“椭圆形”,变化到系统达到燃烧极限时形成的“三角形”分布.加入蓄热小球使高温段平均温度升高、排烟温度降低.燃烧极限与系统半周期、空截面流速及热负荷密切相关.系统能够达到的最低燃烧当量比为0.1.

    Advanced coal and/or biomass based power generation systems offer the potential for high efficiency electricity generation with minimum environmental impact. An important component for many of these advanced power generation cycles is the gas turbine, for which development of a combustion system to burn low calorific value coal derived fuel gas, at turbine inlet temperatures of typically 1 100 - 1 260 deg C and with minimum pollutant emissions, is a key issue. A phased combustor development programme is under-way burning low calorific value fuel gas (3.6 - 4.1 MJ/m{sup 3}) with low emissions, particularly NO{sub x} derived from fuel-bound nitrogen. The first and second phases of the combustor development programme have been completed. The first phase used a generic tubo-annular, prototype combustor based on conventional design principles. Combustor performance for this first prototype combustor was encouraging. The second phase assessed five design variants of the prototype combustor, each variant achieving a progressive improvement in combustor performance. The operating conditions for this assessment were selected to represent a particular medium sized industrial gas turbine operating as part of an Air Blown Gasification Cycle (ABGC). The test conditions assessed therefore included the capability to operate the combustor using natural gas as a supplementary fuel, to suit one possible start-up procedure for the cycle. The paper presents a brief overview of the ABGC development initiative and discusses the general requirements for a gas turbine operating within such a cycle. In addition, it presents full combustor performance results for the second phase of turbine combustor development and discusses the rationale for the progressive design modifications made within that programme. The strategy for the further development of the combustor to burn low calorific value fuel gas with very low conversion of fuel-bound nitrogen to NO{sub x} is presented. (orig.) 6 refs.

    Graphic techniques exist which can accurately predict values for calorific value, organic sulfur, and possibly other constituents of the organic portion of beneficiated coal sample fractions. These techniques also permit a determination of coal rank to be made without the use of the approximations required in the standard procedure. Fractions of IBC-101 with varying ash contents were produced by froth flotation. The various fractions were analyzed by the coal analysis laboratory and the particular data type was plotted in each case vs. the individual ash content of each fraction, using Lotus 123 and Freelace software packages. Such plots for calorific value and organic sulfur have, so far, been made. These curves and the information they contain are discussed in this report. A comparison of the graphic mineral matter value with the usual one calculated from the Parr approximation has been made. Eventually, the data may lead to an effective way to estimate inorganic carbon, hydrogen, nitrogen, and other organic constitents of coal. All data will be made available to researchers.

    The gross calorific value (or higher heating value) of fuelwood is typically 18.6 MJ/kg of dry wood. But the heat energy actually available from combustion of freshly-harvested fuelwood may be as low at 5.9 MJ/kg. For this reason, there is a tendency to overestimate the true energy and economic values of forest biomass with respect to commercial energy sources. This paper interprets the main conventions used in quoting fuel values, and derives simple formulae (and graphs) for estimating energy contents of fuelwood at any given moisture level. The 'usable heat content' approach is developed as an equitable basis for comparing fuel values, and here provides energy and economic equivalents for wood, oil, coal, natural gas and peat. 14 references.

    By gasification with oxygen, municipal waste can be converted into a pure, burnable gas. The gas can be used like natural gas, e.g. in boilers and industrial furnaces, gas engines and gas turbines for heat and electric power generation, but also in chemical synthesis processes, e.g. methanol synthesis. If the right gasification technology is selected, the mineral constitutents of the waste materials can be melted down at the same time, e.g. into a granulate with a glass-like structure that can be used as constructional material.

Soybean varieties in the research were:“Tisa”, “Podravka”, Neoplanta”, “Ika” and “Vita”. Average yield of all examined soybean varieties was 3.06 t/ha. By using 80% soybean straw the best results showed variety Tisa with 48.97 GJ/ha or it is substitute for 1375.19 Nm3/ha of natural gas or 1194 t/ha of oil fuel. They are followed by Tisa, Neoplanta, Podravka, Ika and Vita. These are huge amounts of energy that can be used for soybean drying process and it can be used as energy source for other uses. The estimated fertilization value of harvest soybean leftovers are in the same level as fresh ow or horse manure. Namely, it represents 40% of fertilization value of composted farm manure.

As a way to decrease the influence of stereotypic presumptions in design process, we propose not to disregard the aspect of gender in the design process......, as the perspective brings valuable insights on different approaches to technology, but instead to view gender through a value lens. Contributing to this perspective, we have developed Value Representations as a design-oriented instrument for staging a reflective dialogue with users. Value Representations...

    Large increasing production volumes of automotive shredder residue (ASR) and its hazardous content have raised concerns worldwide. ASR has a desirable calorific value, making its pyrolysis a possible, environmentally friendly and economically viable solution. The present work focuses on the pyrolysis of ASR at temperatures between 950 and 1550°C. Despite the high temperatures, the energy consumption can be minimized as the decomposition of ASR can be completed within a short time. In this study, the composition of ASR was investigated. ASR was found to contain about 3% Ti and plastics of high calorific value such as polypropylene, polyethylene, polycarbonate and polyurethane. Based on thermogravimetric analysis (TGA) of ASR, the non-isothermal degradation kinetic parameters were determined using Coats-Redfern's and Freeman and Carroll methods. The evolved gas analysis indicated that the CH4 was consumed by the reduction of some oxides in ASR. The reduction reactions and the presence of Ti, silicates, C and N in ASR at 1550°C favor the formation of specific ceramics such as TiN and SiC. The presence of nano-ceramics along with a highly-crystalline graphitic carbon in the pyrolysis residues obtained at 1550°C was confirmed by scanning electron microscopy (SEM), X-ray powder diffraction (XRD) and Raman imaging microscope (RIM) analyses.

    A kind of Ⅰ -type radiant tube burner for low heat value gas is successfully developed by experimental study,and the lowest Calorific Value of gas suitable for the burner is up to 4 598 kJ/m3. The results of burner ignition experiment show that the flame detecting signal gradually weakens with the decrease of gas calorific value, and enhances with the increase of air excessive coefficient and gas flow. Besides having the advantage of using low heat value gas, the burner has many other advantages such as high heat efficiency, good temperature uniformity and low emission of NO, and CO.%通过实验研究,得到一种超低热值煤气Ⅰ型辐射管烧嘴,该烧嘴可适用煤气最低热值达4598 kJ/m3(1100kcal/m3).点火实验结果表明:烧嘴火焰检测信号随着煤气热值下降逐步减弱,随着空气消耗系数的增加而增强,随着供气流量的加大而增强.实验烧嘴除可适用低热值煤气外,同时还具有热效率高、加热温度均匀性好和有害气体排放低等优点.

    2014-01-01

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

  15. The value of Leucaena leucocephala bark in leucaena-grass hay diets for Thai goats.

    Palmer, Brian; Jones, Raymond J; Poathong, Somsak; Chobtang, Jeerasak

    2010-12-01

    The study assessed the value of Leucaena leucocephala bark in leucaena-grass hay diets fed to Thai goats. Thai goats in metabolism pens were fed diets containing leucaena leaf (55%) + pangola grass hay (hay, 45%); leucaena leaf (48%) + leucaena bark (9%) + hay (43%); leucaena bark (57%) + hay (43%); and hay only. Feed percentages are expressed on a dry weight basis. The digestibilities of dry matter (DM) and crude protein (CP) were measured for the four diets. Leucaena bark had lower CP concentration than the leaf (11.7 vs. 25.9), and the leucaena bark + hay diet had lower DM and CP digestibility than the other diets. The calculated bark digestibilities of DM and CP of 44.1% and 38.2%, respectively, were much lower than the values for the leucaena leaf of 62.9% and 89.1%, respectively. The lower than expected CP digestibility was attributed to higher tannin levels in the bark compared to the leaves. Despite this, the bark was well accepted by the goats and was often preferred to the hay. Stripping of the bark by goats also results in stems that dry quicker and have higher calorific value as fuel. However, if leucaena branches are fed as a sole diet, the goats may consume up to 30% of bark on a DM basis and this would reduce nutritive value and animal productivity.

    Creating value has been outlined as very central to projects applying the organizational perspective to projects. It has been suggested that value is created in value constellations or project networks, where actors work together to create value. However, research on the value creation process...... in value constellations is scarce, and through an exploratory study of two project networks in a cultural setting we investigate how value is created in value constellations. We outline how each project may be a distinct type of value constellation, one project creates value for the partners of the network...... as a consortium, and the project creates value primarily for others as a facilitator....

    2013-04-01

    Slow and fast pyrolysis of sludge and sludge/disposal filter cake (FC) mix are performed to investigate the liquid and solid products for their use as value added products. The obtained slow pyrolysis liquid products separate in an oil, a water rich fraction and a valuable crystalline solid 5,5-dimethyl hydantoin. During fast pyrolysis, mainly an oil fraction is formed. Aliphatic acids and amides present in the water rich fractions can be considered as value added products and could be purified. The oil fractions have properties which make them promising as fuel (25-35 MJ/kg, 14-20 wt% water content, 0.2-0.6 O/C value), but upgrading is necessary. Sludge/FC oils have a lower calorific value, due to evaporation of alcohols present in FC. ICP-AES analyses reveal that almost none of the metals present in sludge or sludge/FC are transferred towards the liquid fractions. The metals are enriched in the solid fractions.

  19. Indigenous environmental values as human values

    Directory of Open Access Journals (Sweden)

    Monica Gratani

    2016-12-01

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

  20. Use value, exchange value, and resource scarcity

    Energy Technology Data Exchange (ETDEWEB)

    Stern, D.I. [The Australian National University, Canberra (Australia). Centre for Resource and Environmental Studies

    1999-08-01

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

  14. Extreme Value Theory and Value at Risk

    Directory of Open Access Journals (Sweden)

    Viviana Fernandez

    2003-03-01

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

    O’Doherty, John P.

    2015-01-01

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

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

    2015-07-01

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

  19. Values in dialogic pedagogy

    Directory of Open Access Journals (Sweden)

    Eugene Matusov

    2015-02-01

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

  8. Strange Weak Values

    CERN Document Server

    Hosoya, Akio

    2010-01-01

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

  9. Many-valued logics

    CERN Document Server

    Bolc, Leonard

    1992-01-01

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

  11. Values in psychotherapy.

    Science.gov (United States)

    Holmes, J

    1996-01-01

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

  20. Age and Value Orientations

    Directory of Open Access Journals (Sweden)

    Asya Kh. Kukubayeva

    2013-01-01

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

  1. Getting Value from Research

    Science.gov (United States)

    Duke, Charles

    2004-03-01

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

  2. Value of Fundamental Science

    Science.gov (United States)

    Burov, Alexey

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

  3. Multi-valued fields

    CERN Document Server

    Ershov, Yuri L

    2001-01-01

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

    The aim of this paper is to deepen the understanding of the relationship between corporate reputation and financial value. Theories as the resource based view or the contractual view lie ground for the assumption of a linear positive correlation between reputation and financial performance. However......, existing empirical studies have provided conflicting results regarding the direction and strength of this relationship so far. In this paper we claim that the assumption of a direct linear correlation between corporate reputation and financial value misrepresents current financial practices...... and underestimates the complexity of the calculative situations in which values are set on financial markets. Based on in-depth interviews with traders, equity analysts and financial tool developers about the real use of reputation measurement tools, we argue that reputation data rather function as interpretative...

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

  10. Implementing Target Value Design.

    Science.gov (United States)

    Alves, Thais da C L; Lichtig, Will; Rybkowski, Zofia K

    2017-01-01

    An alternative to the traditional way of designing projects is the process of target value design (TVD), which takes different departure points to start the design process. The TVD process starts with the client defining an allowable cost that needs to be met by the design and construction teams. An expected cost in the TVD process is defined through multiple interactions between multiple stakeholders who define wishes and others who define ways of achieving these wishes. Finally, a target cost is defined based on the expected profit the design and construction teams are expecting to make. TVD follows a series of continuous improvement efforts aimed at reaching the desired goals for the project and its associated target value cost. The process takes advantage of rapid cycles of suggestions, analyses, and implementation that starts with the definition of value for the client. In the traditional design process, the goal is to identify user preferences and find solutions that meet the needs of the client's expressed preferences. In the lean design process, the goal is to educate users about their values and advocate for a better facility over the long run; this way owners can help contractors and designers to identify better solutions. This article aims to inform the healthcare community about tools and techniques commonly used during the TVD process and how they can be used to educate and support project participants in developing better solutions to meet their needs now as well as in the future.

  15. Materialistic Values and Goals.

    Science.gov (United States)

    Kasser, Tim

    2016-01-01

    Materialism comprises a set of values and goals focused on wealth, possessions, image, and status. These aims are a fundamental aspect of the human value/goal system, standing in relative conflict with aims concerning the well-being of others, as well as one's own personal and spiritual growth. Substantial evidence shows that people who place a relatively high priority on materialistic values/goals consume more products and incur more debt, have lower-quality interpersonal relationships, act in more ecologically destructive ways, have adverse work and educational motivation, and report lower personal and physical well-being. Experimentally activating materialistic aims causes similar outcomes. Given these ills, researchers have investigated means of decreasing people's materialism. Successful interventions encourage intrinsic/self-transcendent values/goals, increase felt personal security, and/or block materialistic messages from the environment. These interventions would likely be more effective if policies were also adopted that diminished contemporary culture's focus on consumption, profit, and economic growth.

  5. Radiology's value chain.

    Enzmann, Dieter R

    2012-04-01

    A diagnostic radiology value chain is constructed to define its main components, all of which are vulnerable to change, because digitization has caused disaggregation of the chain. Some components afford opportunities to improve productivity, some add value, while some face outsourcing to lower labor cost and to information technology substitutes, raising commoditization risks. Digital image information, because it can be competitive at smaller economies of scale, allows faster, differential rates of technological innovation of components, initiating a centralization-to-decentralization technology trend. Digitization, having triggered disaggregation of radiology's professional service model, may soon usher in an information business model. This means moving from a mind-set of "reading images" to an orientation of creating and organizing information for greater accuracy, faster speed, and lower cost in medical decision making. Information businesses view value chain investments differently than do small professional services. In the former model, producing a better business product will extend image interpretation beyond a radiologist's personal fund of knowledge to encompass expanding external imaging databases. A follow-on expansion with integration of image and molecular information into a report will offer new value in medical decision making. Improved interpretation plus new integration will enrich and diversify radiology's key service products, the report and consultation. A more robust, information-rich report derived from a "systems" and "computational" radiology approach will be facilitated by a transition from a professional service to an information business. Under health care reform, radiology will transition its emphasis from volume to greater value. Radiology's future brightens with the adoption of a philosophy of offering information rather than "reads" for decision making. Staunchly defending the status quo via turf wars is unlikely to constitute a

    Last week, the Industrial Services and General Infrastructure section of the Procurement and Industrial Services group received dozens of bids in a single day! The bids were submitted in response to four invitations to tender to be adjudicated on a ‘best value for money’ basis. This adjudication method, introduced at CERN in 2008, ensures that quality is given as much priority as cost containment in the process of awarding industrial services contracts.   Members of the Industrial Services and General Infrastructure section with the dozens of bids received in a single day. Until 2008 every contract at CERN was adjudicated on a "lowest compliant bid" basis, i.e. to the firm submitting the cheapest technically compliant tender. Since then, however, the CERN Financial Rules, including the Procurement Rules, have undergone an in-depth revision, and the ‘best value for money’ adjudication basis has been introduced.

    Full Text Available This article investigates the current data management practices of university researchers at an Intermountain West land-grant research university in the United States. Key findings suggest that researchers are primarily focused on the collection and housing of research data. However, additional research value exists within the other life cycle stages for research data—specifically in the stages of delivery and maintenance. These stages are where most new demands and requirements exist for data management plans and policies that are conditional for external grant funding; therefore, these findings expose a “gap” in current research practice. These findings should be of interest to academics and practitioners alike as findings highlight key management gaps in the life cycle of research data. This study also suggests a course of action for academic institutions to coalesce campus-wide assets to assist researchers in improving research value.

  11. Complex-valued autoencoders.

    Baldi, Pierre; Lu, Zhiqin

    2012-09-01

    Autoencoders are unsupervised machine learning circuits, with typically one hidden layer, whose learning goal is to minimize an average distortion measure between inputs and outputs. Linear autoencoders correspond to the special case where only linear transformations between visible and hidden variables are used. While linear autoencoders can be defined over any field, only real-valued linear autoencoders have been studied so far. Here we study complex-valued linear autoencoders where the components of the training vectors and adjustable matrices are defined over the complex field with the L(2) norm. We provide simpler and more general proofs that unify the real-valued and complex-valued cases, showing that in both cases the landscape of the error function is invariant under certain groups of transformations. The landscape has no local minima, a family of global minima associated with Principal Component Analysis, and many families of saddle points associated with orthogonal projections onto sub-space spanned by sub-optimal subsets of eigenvectors of the covariance matrix. The theory yields several iterative, convergent, learning algorithms, a clear understanding of the generalization properties of the trained autoencoders, and can equally be applied to the hetero-associative case when external targets are provided. Partial results on deep architecture as well as the differential geometry of autoencoders are also presented. The general framework described here is useful to classify autoencoders and identify general properties that ought to be investigated for each class, illuminating some of the connections between autoencoders, unsupervised learning, clustering, Hebbian learning, and information theory.

    In addition to its intrinsic value (nature working as it is; species are the product of a long history of continuing evolution by means of ecological processes, and so they have the right to continued existence), biodiversity also plays a fundamental role as ecosystem services in the maintenance of natural ecological processes. The economic or utilitarian values of biodiversity rely upon the dependence of man on biodiversity; products that nature can provide: wood, food, fibers to make paper, resins, chemical organic products, genes as well as knowledge for biotechnology, including medicine and cosmetic sub-products. It also encompasses ecosystem services, such as climate regulation, reproductive and feeding habitats for commercial fish, some organisms that can create soil fertility through complex cycles and interactions, such as earthworms, termites and bacteria, in addition to fungi responsible for cycling nutrients like nitrogen, phosphorus and sulfur and making them available to plant absorption. These services are the benefits that people indirectly receive from natural ecosystem functions (air quality maintenance, regional climate, water quality, nutrient cycling, reproductive habitats of commercial fish, etc.) with their related economic values.

    2012-11-07

    Reputation plays a central role in human societies. Empirical and theoretical work indicates that a good reputation is valuable in that it increases one's expected payoff in the future. Here, we explore a game that couples a repeated Prisoner's Dilemma (PD), in which participants can earn and can benefit from a good reputation, with a market in which reputation can be bought and sold. This game allows us to investigate how the trading of reputation affects cooperation in the PD, and how participants assess the value of having a good reputation. We find that depending on how the game is set up, trading can have a positive or a negative effect on the overall frequency of cooperation. Moreover, we show that the more valuable a good reputation is in the PD, the higher the price at which it is traded in the market. Our findings have important implications for the use of reputation systems in practice.

  3. The value of victory

    2008-10-01

    Full Text Available Auctions, normally considered as devices facilitating trade, also provide a way to probe mechanisms governing one's valuation of some good or action. One of the most intriguing phenomena in auction behavior is the winner's curse --- the strong tendency of participants to bid more than rational agent theory prescribes, often at a significant loss. The prevailing explanation suggests that humans have limited cognitive abilities that make estimating the correct bid difficult, if not impossible. Using a series of auction structures, we found that bidding approaches rational agent predictions when participants compete against a computer. However, the winner's curse appears when participants compete against other humans, even when cognitive demands for the correct bidding strategy are removed. These results suggest the humans assign significant future value to victories over human but not over computer opponents even though such victories may incur immediate losses, and that this valuation anomaly is the origin of apparently irrational behavior.

    The theory of valued difference fields $(K, \\sigma, v)$ depends on how the valuation $v$ interacts with the automorphism $\\sigma$. Two special cases have already been worked out - the isometric case, where $v(\\sigma(x)) = v(x)$ for all $x\\in K$, has been worked out by Luc Belair, Angus Macintyre and Thomas Scanlon; and the contractive case, where $v(\\sigma(x)) > n\\cdot v(x)$ for all $n\\in\\mathbb{N}$ and $x\\in K^\\times$ with $v(x) > 0$, has been worked out by Salih Azgin. In this paper we deal with a more general version, called the multiplicative case, where $v(\\sigma(x)) = \\rho\\cdot v(x)$, where $\\rho (> 0)$ is interpreted as an element of a real-closed field. We give an axiomatization and prove a relative quantifier elimination theorem for such a theory.

    Full Text Available Narrow self-interest is often used as a simplifying assumption when studying people making decisions in social contexts. Nonetheless, people exhibit a wide range of different motivations when choosing unilaterally among interdependent outcomes. Measuring the magnitude of the concern people have for others, sometimes called Social Value Orientation (SVO, has been an interest of many social scientists for decades and several different measurement methods have been developed so far. Here we introduce a new measure of SVO that has several advantages over existent methods. A detailed description of the new measurement method is presented, along with norming data that provide evidence of its solid psychometric properties. We conclude with a brief discussion of the research streams that would benefit from a more sensitive and higher resolution measure of SVO, and extend an invitation to others to use this new measure which is freely available.

  9. The innovation value chain.

    2007-06-01

    The challenges of coming up with fresh ideas and realizing profits from them are different for every company. One firm may excel at finding good ideas but may have weak systems for bringing them to market. Another organization may have a terrific process for funding and rolling out new products and services but a shortage of concepts to develop. In this article, Hansen and Birkinshaw caution executives against using the latest and greatest innovation approaches and tools without understanding the unique deficiencies in their companies' innovation systems. They offer a framework for evaluating innovation performance: the innovation value chain. It comprises the three main phases of innovation (idea generation, conversion, and diffusion) as well as the critical activities performed during those phases (looking for ideas inside your unit; looking for them in other units; looking for them externally; selecting ideas; funding them; and promoting and spreading ideas companywide). Using this framework, managers get an end-to-end view of their innovation efforts. They can pinpoint their weakest links and tailor innovation best practices appropriately to strengthen those links. Companies typically succumb to one of three broad "weakest-link" scenarios. They are idea poor, conversion poor, or diffusion poor. The article looks at the ways smart companies - including Intuit, P&G, Sara Lee, Shell, and Siemens- modify the best innovation practices and apply them to address those organizations' individual needs and flaws. The authors warn that adopting the chain-based view of innovation requires new measures of what can be delivered by each link in the chain. The approach also entails new roles for employees "external scouts" and "internal evangelists," for example. Indeed, in their search for new hires, companies should seek out those candidates who can help address particular weaknesses in the innovation value chain.

    Full Text Available Over the last two decades, inclusion and participation have become leading policy concepts within the Dutch chronic care and social welfare sector. People with an intellectual or psychiatric disability ought to get a chance to participate in, and belong to, the mainstream of our society—on the basis of equality and equivalence. Although on an international level this pursuit has been going on for at least five decades, it still raises all kinds of questions and debates. What does it mean if we want people with intellectual and/or psychiatric disabilities to participate in our society? Based on which idea(ls about humanity do we define equality and equivalence? And by doing so, how much space is left for individual differences? In the following dialogue the two authors navigate the tension between similarity and difference in thinking about—and working towards—more space for marginalized people. In an attempt to withstand the contemporary dominance of equality thinking, marked by a strong focus on tenability and autonomy—and by extension an increasing climate of taboo around vulnerability and dependency—both authors stress the importance of recognizing and valuing difference, while discussing encounters between people with and without a severe intellectual and/or multiple disability.

  11. Reference change values.

    Fraser, Callum G

    2011-09-30

    Reference change values (RCV) provide objective tools for assessment of the significance of differences in serial results from an individual. The concept is simple and the calculation easy, since all laboratories know their analytical imprecision (CV(A)) and estimates of within-subject biological variation (CV(I)) are available for a large number of quantities. Generally, CV(I) are constant over time, geography, methodology and in health and chronic stable disease. The formula is RCV=2(1/2) · Z · (CV(A)(2) + CV(I)(2))(1/2), where Z is the number of standard deviations appropriate to the probability. Correct interpretation of the semantics describing the clinical use of RCV is vital for selection of the Z-score. Many quantities of clinically importance exist for which good estimates of RCV are unavailable. Derivation of CV(I) may be difficult for such quantities: flair and imagination are required in selecting populations with chronic but stable disease on whom CV(I) can be determined. RCV can be used for delta-checking and auto-verification and laboratory information management systems (LIMS) can be adapted to do this. Recently, log-normal transformation to obtain unidirectional RCV has been used. Gaps in knowledge of RCV still require filling since the need for measures of change is clearly expressed in guidelines.

    2015-11-01

    Full Text Available Digital information changes the ways in which people and organisations interact. This paper examines the nature of this change in the context of the author’s Model for Information (MfI. It investigates the relationship between outcomes and value, selection processes and some attributes of information and explores how this relationship changes in the move from analogue to digital information. Selection processes shape the evolution of information ecosystems in which conventions are established for the ways in which information is used. The conventions determine norms for information friction and information quality as well as the sources of information and channels used. Digital information reduces information friction, often dramatically, and changes information quality. The increasing use of analytics in business increasingly delivers predictive or prescriptive digital information. These changes are happening faster than information ecosystem conventions can change. The relationships established in the paper enable an analysis of, and guide changes to, these conventions enabling a more effective use of digital information.

    Full Text Available When Su Cleyle and I first decided to start Evidence Based Library and Information Practice, one of the things we agreed upon immediately was that the journal be open access. We knew that a major obstacle to librarians using the research literature was that they did not have access to the research literature. Although Su and I are both academic librarians who can access a wide variety of library and information literature from our institutions, we belong to a profession where not everyone has equal access to the research in our field. Without such access to our own body of literature, how can we ever hope for practitioners to use research evidence in their decision making? It would have been contradictory to the principles of evidence based library and information practice to do otherwise.One of the specific groups we thought could use such an open access venue for discovering research literature was school librarians. School librarians are often isolated and lacking access to the research literature that may help them prove to stakeholders the importance of their libraries and their role within schools. Certainly, school libraries have been in decline and the use of evidence to show value is needed. As Ken Haycock noted in his 2003 report, The Crisis in Canada’s School Libraries: The Case for Reform and Reinvestment, “Across the country, teacher-librarians are losing their jobs or being reassigned. Collections are becoming depleted owing to budget cuts. Some principals believe that in the age of the Internet and the classroom workstation, the school library is an artifact” (9. Within this context, school librarians are looking to our research literature for evidence of the impact that school library programs have on learning outcomes and student success. They are integrating that evidence into their practice, and reflecting upon what can be improved locally. They are focusing on students and showing the impact of school libraries and

  17. Reinforcement Learning by Value Gradients

    CERN Document Server

    Fairbank, Michael

    2008-01-01

    The concept of the value-gradient is introduced and developed in the context of reinforcement learning. It is shown that by learning the value-gradients exploration or stochastic behaviour is no longer needed to find locally optimal trajectories. This is the main motivation for using value-gradients, and it is argued that learning value-gradients is the actual objective of any value-function learning algorithm for control problems. It is also argued that learning value-gradients is significantly more efficient than learning just the values, and this argument is supported in experiments by efficiency gains of several orders of magnitude, in several problem domains. Once value-gradients are introduced into learning, several analyses become possible. For example, a surprising equivalence between a value-gradient learning algorithm and a policy-gradient learning algorithm is proven, and this provides a robust convergence proof for control problems using a value function with a general function approximator.

    2008-09-01

    The purpose of this study was to measure professional and personal values among nurses, and to identify the factors affecting these values. The participants were 323 Israeli nurses, who were asked about 36 personal values and 20 professional values. The three fundamental professional nursing values of human dignity, equality among patients, and prevention of suffering, were rated first. The top 10 rated values all concerned nurses' responsibility towards patients. Altruism and confidentiality were not highly rated, and health promotion and nursing research were rated among the last three professional values. For personal (instrumental) values, honesty, responsibility and intelligence were rated first, while ambition and imagination were rated 14th and 16th respectively out of 18. Significant differences (P personal and professional values rated as functions of culture, education, professional seniority, position and field of expertise. The results may assist in understanding the motives of nurses with different characteristics and help to promote their work according to professional ethical values.

We derive a value-added REER describing how demand for the value added that a country produces changes as the price of its value added changes relative to competitors. We then compute this index for 42 countries from 1970-2009 using trade measured in value added terms and GDP deflators. There are substantial differences between value-added and conven...

  1. Organization of fuel accounting and determining the efficiency of combustion of wood fuel in boiler houses

    Energy Technology Data Exchange (ETDEWEB)

    Pavlosyuk, V.A.

    1982-01-01

    A review is presented of official Soviet publications covering general principles, calorific value of wood species and waste wood, and specific fuel requirements of different boilers. Accounting is based on the concept of nominal fuel (calorific value 7000 kcal/kg). Reduced boiler efficiency when burning low-grade fuel, e.g. waste wood of 55% moisture content, results in higher fuel consumption than expected from the calorific value alone. A method of estimating normal fuel requirements is described. 3 references.

  2. Neurobiology of value integration: when value impacts valuation.

    Park, Soyoung Q; Kahnt, Thorsten; Rieskamp, Jörg; Heekeren, Hauke R

    2011-06-22

    Everyday choice options have advantages (positive values) and disadvantages (negative values) that need to be integrated into an overall subjective value. For decades, economic models have assumed that when a person evaluates a choice option, different values contribute independently to the overall subjective value of the option. However, human choice behavior often violates this assumption, suggesting interactions between values. To investigate how qualitatively different advantages and disadvantages are integrated into an overall subjective value, we measured the brain activity of human subjects using fMRI while they were accepting or rejecting choice options that were combinations of monetary reward and physical pain. We compared different subjective value models on behavioral and neural data. These models all made similar predictions of choice behavior, suggesting that behavioral data alone are not sufficient to uncover the underlying integration mechanism. Strikingly, a direct model comparison on brain data decisively demonstrated that interactive value integration (where values interact and affect overall valuation) predicts neural activity in value-sensitive brain regions significantly better than the independent mechanism. Furthermore, effective connectivity analyses revealed that value-dependent changes in valuation are associated with modulations in subgenual anterior cingulate cortex-amygdala coupling. These results provide novel insights into the neurobiological underpinnings of human decision making involving the integration of different values.

    Brcic, Jelena; Della-Rossa, Irina

    2012-11-01

    Values are desirable, trans-situational goals, varying in importance, that guide behavior. Research has demonstrated that universal values may alter in importance as a result of major life events. The present study examines the effect of spaceflight and the demands of astronauts' job position as life circumstances that affect value priorities. We employed thematic content analysis for references to Schwartz's well-established value markers in narratives (media interviews, journals, and pre-flight interviews) of seven Canadian astronauts and compared the results to the values of National Aeronautics and Space Administration (NASA) and Russian Space Agency (RKA) astronauts. Space flight did alter the level of importance of Canadian astronauts' values. We found a U-shaped pattern for the values of Achievement and Tradition before, during, and after flight, and a linear decrease in the value of Stimulation. The most frequently mentioned values were Achievement, Universalism, Security, and Self-Direction. Achievement and Self Direction are also within the top 4 values of all other astronauts; however, Universalism was significantly higher among the Canadian astronauts. Within the value hierarchy of Canadian astronauts, Security was the third most frequently mentioned value, while it is in seventh place for all other astronauts. Interestingly, the most often mentioned value marker (sub-category) in this category was Patriotism. The findings have important implications in understanding multi-national crew relations during training, flight, and reintegration into society.

    Although image interpretation is an essential part of radiologists' value, there are other ways in which we contribute to patient care. Part II of the value of imaging series reviews current initiatives that demonstrate value beyond the image interpretation. Standardizing processes, reducing the radiation dose of our examinations, clarifying written reports, improving communications with patients and providers, and promoting appropriate imaging through decision support are all ways we can provide safer, more consistent, and higher quality care. As payers and policy makers push to drive value, research that demonstrates the value of these endeavors, or lack thereof, will become increasingly sought after and supported.

    The patient-centered medical home (PCMH) model provides a compelling vision for primary care transformation, but studies of its impact have used insufficiently patient-centered metrics with inconsistent results. We propose a framework for defining patient-centered value and a new model for value-based primary care transformation: the primary care value model (PCVM). We advocate for use of patient-centered value when measuring the impact of primary care transformation, recognition, and performance-based payment; for financial support and research and development to better define primary care value-creating activities and their implementation; and for use of the model to support primary care organizations in transformation.

  18. Neurocognitive Mechanisms Underlying Value-Based Decision-Making: From Core Values to Economic Value

    Directory of Open Access Journals (Sweden)

    Tobias eBrosch

    2013-07-01

    Full Text Available Value plays a central role in practically every aspect of human life that requires a decision: whether we choose between different consumer goods, whether we decide which person we marry or which political candidate gets our vote, we choose the option that has more value to us. Over the last decade, neuroeconomic research has mapped the neural substrates of economic value, revealing that activation in brain regions such as ventromedial prefrontal cortex (VMPFC, ventral striatum or posterior cingulate cortex reflects how much an individual values an option and which of several options he/she will choose. However, while great progress has been made exploring the mechanisms underlying concrete decisions, neuroeconomic research has been less concerned with the questions of why people value what they value, and why different people value different things. Social psychologists and sociologists have long been interested in core values, motivational constructs that are intrinsically linked to the self-schema and are used to guide actions and decisions across different situations and different time points. Core value may thus be an important determinant of individual differences in economic value computation and decision-making. Based on a review of recent neuroimaging studies investigating the neural representation of core values and their interactions with neural systems representing economic value, we outline a common framework that integrates the core value concept and neuroeconomic research on value-based decision-making.

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

    Science.gov (United States)

    Skeggs, Bev

    2014-03-01

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

  19. What Is the Value of Value-Based Purchasing?

    Science.gov (United States)

    Tanenbaum, Sandra J

    2016-10-01

    Value-based purchasing (VBP) is a widely favored strategy for improving the US health care system. The meaning of value that predominates in VBP schemes is (1) conformance to selected process and/or outcome metrics, and sometimes (2) such conformance at the lowest possible cost. In other words, VBP schemes choose some number of "quality indicators" and financially incent providers to meet them (and not others). Process measures are usually based on clinical science that cannot determine the effects of a process on individual patients or patients with comorbidities, and do not necessarily measure effects that patients value; additionally, there is no provision for different patients valuing different things. Proximate outcome measures may or may not predict distal ones, and the more distal the outcome, the less reliably it can be attributed to health care. Outcome measures may be quite rudimentary, such as mortality rates, or highly contestable: survival or function after prostate surgery? When cost is an element of value-based purchasing, it is the cost to the value-based payer and not to other payers or patients' families. The greatest value of value-based purchasing may not be to patients or even payers, but to policy makers seeking a morally justifiable alternative to politically contested regulatory policies.

    The basic financial purpose of a firm is to maximize its value. An inventory management system should also contribute to realization of this basic aim.

    We will demonstrate in this paper that Bell's theorem (Bell's inequality) does not really conflict with quantum mechanics, the controversy between them originates from the different definitions for the expectation value using the probability distribution in Bell's inequality and the expectation value in quantum mechanics. We can not use quantum mechanical expectation value measured in experiments to show the violation of Bell's inequality and then further deny the local hidden-variables theor...

    Full Text Available The aim of the article. The phases of the Porter's value chain are distinguished: construction of chain value – Porters model (Stage 1; deconstruction – identifying contradictions, disorganizing elements of unnecessary processes that do not add value (Stage 2; reconstruction (synthesis – creates a new value chain (Stage 3. The results of the analysis. The principles of convergence of value and supply chains are identified and the need to focus on supply chain performance is proved. The dependence of design value chain/supply chain on the chosen general strategy and the need to subject its reconstruction process of deconstruction + reconstruction in case of changes or modifications as to this strategy is grounded. The impacts on the creation of value in the Porter’s chain are accepted. The need to identify for each working block of micro factors that affect the financial factors (macro factors that is net and operating profit, investments into fixed and working capital, the cost of companies capital is proved. Such classification allows to determine what types of management actions or motivations for managers of lower level must be selected. It is revealed that in addition to measurable factors-generators on cost to the value chain the indirect (mediated factors have an impact, especially when the management is replaced by objectives and values of enterprise management use. It is proved that the problem of environment and society in the concept of sustainable development, social responsibility, marketing value of 3.0 outlines another group of factors influencing the Porter’s value chain, as evidenced by the current trend of prioritization of human values. It is proved that companies, especially global ones, give the increasing domination of human values in B2B and B2C transactions at the maturity stage in their life cycle in the structure of forced strategic objectives and make adjustments by modifying the cited above vision and mission

  7. Valuing future citizens' values regarding risk

    Energy Technology Data Exchange (ETDEWEB)

    Fleming, Patricia [Creighton Univ., Omaha (United States). College of Arts and Sciences/Philosophy

    2006-09-15

    Valuing present citizen's values regarding the risks they face is an important aspect of risk assessment and risk acceptability. Conferences like VALDOR are held for this reason. Governments like Sweden have national referendums on various risk-prone enterprises. The results of these referendums can determine the future of these programs. In the United States, when guidelines are set for determining acceptable levels of risk, the relevant federal agencies are often required to provide a comment period regarding proposed guidelines in order to ascertain the judgments, including the weights place on certain values, of individual members of society as well as stakeholder groups. After the comment period ends, the agency decides on the acceptable level of risk, taking into account the comments from present citizens. Do we also have a duty to value the not-yet-existing values of future citizens, especially if the risks created by the activities of present citizens extend into the future to citizens not yet living? If so, are there any circumstances which entitle us to de-value those not-yet-existing values. In this paper, I ground my discussion of the question of valuing future citizens' values in one of the areas of focus of the VALDOR conference: nuclear waste management and specifically the question facing the United States' program regarding an acceptable dose standard associated with the release of radioactivity into the biosphere from an underground repository. The underlying conference theme to which this discussion may be attached is community environmental justice as it applies to future citizens. I focus on the role that uncertainty plays is providing justice between present and future citizens.

    2006-11-01

    Two studies are described examining the correlation between self- and culture-referenced values at a culture level (Study 1) and correlation between self- and culture-referenced values and self-reported behavior at an individual level (Study 2). It is found that values related to individual-group relationships (embeddedness) and expression and experience of affective feelings and emotions (affective autonomy) are significantly correlated at a culture level. In Study 2, culture-referenced values are shown to correlate with behaviors attached to social norms, whereas self-rated values are found to correlate with behaviors that are not norm-governed. Implications for measurement of cultural values and cultural and cross-cultural research designs are discussed.

  14. Debate Regarding Measuring Accounting Value: Historical Cost against Fair Value

    Directory of Open Access Journals (Sweden)

    Victor Munteanu

    2015-12-01

    Full Text Available The transition from historical cost to fair value represents an option with major implications in accounting, because it is a complex process that requires tuning to today’s trends of national and global economy. We can state that with all the advantages of using historical cost it has its limitations and it is” getting old”. That doesn’t mean that will be abandoned but substituted when it is needed with another value. At present, the lack of historical value is inconceivable; many practitioners consider it to be the best method to evaluate assets.

  15. Analysing performance through value creation

    Directory of Open Access Journals (Sweden)

    Adrian TRIFAN

    2015-12-01

    Full Text Available This paper draws a parallel between measuring financial performance in 2 variants: the first one using data offered by accounting, which lays emphasis on maximizing profit, and the second one which aims to create value. The traditional approach to performance is based on some indicators from accounting data: ROI, ROE, EPS. The traditional management, based on analysing the data from accounting, has shown its limits, and a new approach is needed, based on creating value. The evaluation of value based performance tries to avoid the errors due to accounting data, by using other specific indicators: EVA, MVA, TSR, CVA. The main objective is shifted from maximizing the income to maximizing the value created for shareholders. The theoretical part is accompanied by a practical analysis regarding the creation of value and an analysis of the main indicators which evaluate this concept.

    This paper characterizes the quasilocal fields from the class of Henselian valued fields with totally indivisible value groups, which possess finite separable extensions of nontrivial defect. We show that, for any prime number $q$, a divisible subgroup $T$ in the multiplicative group of complex numbers is realizable as the Brauer group of such a quasilocal field of residual characteristic $q$ unless $q = 2$ and the $2$-component of T$ is trivial.

Methods: The sample consisted of 158 university students aged 19-24 years (mean age = 20.8 and 170 humanities workers aged 29-48 years (mean age=36.8. Respondents were divided into following groups: men (N = 72, women (N = 256, students’ school results A (N = 43, B (N = 47, C (N = 35, D (N = 29, E (N = 4 and worker´s branch of occupation: teachers in the kindergarten (N = 34, special education teachers (N = 32, high school teachers (N = 47, educational workers (N = 31 and civil servants (N = 26. We used a Rokeach Value Survey (RVS which is designed to measure two sets of values. One set is composed of 18 terminal values or desired end states of existence (e.g., an exciting life, national security, and the other set is composed of 18 instrumental values, or preferable modes of behavior (e.g., being ambitious, independent. Then, subjects are asked to rank order each value as to its importance as a guiding principle in their life. A 1 indicates the most important value and an 18 the least important. Scale responses are considered ordinal.Data were analyzed using SPSS. Results: We analyzed the preference of values depending on the gender. Pearson’s ?2 analyses indicated that men are significantly more (often „Effective Crusaders“ than women and women are significantly more (often „Virtuous Advocates“ than men, ?2 (3 = 13.817, p= .003, ?c = .205.

    Directory of Open Access Journals (Sweden)

    NICOLAE SICHIGEA

    2015-12-01

    Full Text Available The financial theory developed different categories of indicators - traditional and modern - in order to evaluate the firm’s value creation. The shareholders are directly interested by the value added in the company. The value creation is a complex process that implies correct decisions, common responsibility (managers and shareholders and actions towards an efficient and profitable activity. The traditional indicators of performance are not teoritically correlated with the the value creation and in these circumstances, should be used appropriate financial indicators in order to reflect the value of the company. Therefore, the modern indicators used in the value based management framework offer a greater flexibility and efficiency and represent a good alternative for companies. Such performance indicators used to measure the financial results correlated with shareholder wealth are the Economic Value Added (EVA, as a measure of internal performance and the Market Value Added (MVA as a measure of external performance of the company. Starting from the main deficiencies of the accounting indicators, the objective of this this study is to present the relationship between EVA and MVA and their implications on firms’valuation. Thus, the presentation and analysis of these indicators – EVA and MVA - will underline the main features, their correlations, and influence factors but also the main advantage and disadvantage of each indicator, which will enable the managers to make the correct choice and subsequently the best decision regarding the performance measures.

  9. The fitness value of information

    CERN Document Server

    Bergstrom, Carl T

    2007-01-01

    Biologists measure information in different ways. Neurobiologists and researchers in bioinformatics often measure information using information-theoretic measures such as Shannon's entropy or mutual information. Behavioral biologists and evolutionary ecologists more commonly use decision-theoretic measures, such the value of information, which assess the worth of information to a decision maker. Here we show that these two kinds of measures are intimately related in the context of biological evolution. We present a simple model of evolution in an uncertain environment, and calculate the increase in Darwinian fitness that is made possible by information about the environmental state. This fitness increase -- the fitness value of information -- is a composite of both Shannon's mutual information and the decision-theoretic value of information. Furthermore, we show that in certain cases the fitness value of responding to a cue is exactly equal to the mutual information between the cue and the environment. In gen...

  12. OFFSHORING FOR SUSTAINABLE VALUE MANAGEMENT

    Directory of Open Access Journals (Sweden)

    Thaddeus Oforegbunam Ebiringa

    2014-05-01

    Full Text Available This paper evaluates offshoring as a strategic value management initiative using Cadbury Nigeria Plc as a case study. Through offshoring risks associated with inventory holding are hedged. A comparative analysis of in-house and offshored cost profiles as well as critical risk factors that affect firm value are evaluated. The result shows that offshoring led to immediate costs saving, freeing of funds previously held in inventory for other working capital investments as well as profitability for vendors. However, aside financial benefits to partners, it leads to increased stakeholders awareness, shared values, partnerships, teamwork and risk mitigation. It therefore follows that for sustainability of financial benefits of offshoring, concerted effort must be made by partners to ensure that critical drivers of value management are not compromised.

It is an undeniable fact that the phenomenon is lived in Europe with concern because of its consequences. People who live and coexist in Europe represent a huge cultural variety. Therefore, social and cultural gaps that can affect the basic values of the western societies seem to be inevitable due to the dimensions of the current migration phenomenon. The present studies are based on the European Social Survey Questionnaire (2002, and the Portrait Values Questionnaire (Schwartz, 1992, 2001 and focuses on the relevance of cultural values to explain the acceptance or rejection of the immigrant.. Finally, we emphasize the importance of cultural values -like Harmony or Egalitarianism- for any initiative or social policy which aimes at reducing the problems concerning inmigration in the European context.

  20. A nomogram for P values

    Directory of Open Access Journals (Sweden)

    Held Leonhard

    2010-03-01

    Full Text Available Abstract Background P values are the most commonly used tool to measure evidence against a hypothesis. Several attempts have been made to transform P values to minimum Bayes factors and minimum posterior probabilities of the hypothesis under consideration. However, the acceptance of such calibrations in clinical fields is low due to inexperience in interpreting Bayes factors and the need to specify a prior probability to derive a lower bound on the posterior probability. Methods I propose a graphical approach which easily translates any prior probability and P value to minimum posterior probabilities. The approach allows to visually inspect the dependence of the minimum posterior probability on the prior probability of the null hypothesis. Likewise, the tool can be used to read off, for fixed posterior probability, the maximum prior probability compatible with a given P value. The maximum P value compatible with a given prior and posterior probability is also available. Results Use of the nomogram is illustrated based on results from a randomized trial for lung cancer patients comparing a new radiotherapy technique with conventional radiotherapy. Conclusion The graphical device proposed in this paper will enhance the understanding of P values as measures of evidence among non-specialists.

  1. The relative value of growth.

    Science.gov (United States)

    Mass, Nathaniel J

    2005-04-01

    Most executives would say that adding a point of growth and gaining a point of operating-profit margin contribute about equally to shareholder value. Margin improvements hit the bottom line immediately, while growth compounds value over time. But the reality is that the two are rarely equivalent. Growth often is far more valuable than managers think. For some companies, convincing the market that they can grow by just one additional percentage point can be worth six, seven, or even ten points of margin improvement. This article presents a new strategic metric, called the relative value of growth (RVG), which gives managers a clear picture of how growth projects and margin improvement initiatives affect shareholder value. Using basic balance sheet and income sheet data, managers can determine their companies' RVGs, as well as those of their competitors. Calculating RVGs gives managers insights into which corporate strategies are working to deliver value and whether their companies are pulling the most powerful value-creation levers. The author examines a number of well-known companies and explains what their RVG numbers say about their strategies. He reviews the unspoken assumption that growth and profits are incompatible over the long term and shows that a fair number of companies are effective at delivering both. Finally, he explains how managers can use the RVG framework to help them define strategies that balance growth and profitability at both the corporate and business unit levels.

  2. Applied extreme-value statistics

    Energy Technology Data Exchange (ETDEWEB)

    Kinnison, R.R.

    1983-05-01

    The statistical theory of extreme values is a well established part of theoretical statistics. Unfortunately, it is seldom part of applied statistics and is infrequently a part of statistical curricula except in advanced studies programs. This has resulted in the impression that it is difficult to understand and not of practical value. In recent environmental and pollution literature, several short articles have appeared with the purpose of documenting all that is necessary for the practical application of extreme value theory to field problems (for example, Roberts, 1979). These articles are so concise that only a statistician can recognise all the subtleties and assumptions necessary for the correct use of the material presented. The intent of this text is to expand upon several recent articles, and to provide the necessary statistical background so that the non-statistician scientist can recognize and extreme value problem when it occurs in his work, be confident in handling simple extreme value problems himself, and know when the problem is statistically beyond his capabilities and requires consultation.

  3. Unsharp Values, Domains and Topoi

    CERN Document Server

    Doering, Andreas

    2011-01-01

    The so-called topos approach provides a radical reformulation of quantum theory. Structurally, quantum theory in the topos formulation is very similar to classical physics. There is a state object, analogous to the state space of a classical system, and a quantity-value object, generalising the real numbers. Physical quantities are maps from the state object to the quantity-value object -- hence the `values' of physical quantities are not just real numbers in this formalism. Rather, they are families of real intervals, interpreted as `unsharp values'. We will motivate and explain these aspects of the topos approach and show that the structure of the quantity-value object can be analysed using tools from domain theory, a branch of order theory that originated in theoretical computer science. Moreover, the base category of the topos associated with a quantum system turns out to be a domain if the underlying von Neumann algebra is a matrix algebra. For general algebras, the base category still is a highly struct...

  8. Professional values, aesthetic values, and the ends of trade.

    Science.gov (United States)

    Edgar, Andrew

    2011-05-01

    Professionalism is initially understood as a historical process, through which certain commercial services sought to improve their social status (and economic reward) by separating themselves from mere crafts or trades. This process may be traced clearly with the aspiration of British portrait painters (headed by Sir Joshua Reynolds), in the eighteenth century, to acquire a social status akin to that of already established professionals, such as clerics and doctors. This may be understood, to a significant degree, as a process of gentrification. The values of the professional thereby lie as much in the etiquette and other social skills with which they deal with their clients, than with any distinctive form of skill or value. Professionalisation as gentrification seemingly says little about the nature of modern professionalism. However, if this process is also construed as one in which the goals and achievements of the profession come to be subject to radical reflection, then something significant about professional values emerges. On this account, the profession is distinguished from craft or trade on the grounds that the goals of the profession, and the effectiveness of any attempt to realise them, are not transparent to the client. While a lay person will typically have the competence necessary to judge whether or not a craft worker has achieved their goal, that person will not necessarily be able to recognise the values that determine the success of a medical operation. It will be concluded that the values of a profession are articulated intrinsically to the profession, in terms of the contested understanding that the professionals themselves have of the meaning of the profession and the narratives within which its history is to be told.

  9. The Value Question in Metaphysics.

    Science.gov (United States)

    Kahane, Guy

    2012-07-01

    Much seems to be at stake in metaphysical questions about, for example, God, free will or morality. One thing that could be at stake is the value of the universe we inhabit-how good or bad it is. We can think of competing philosophical positions as describing possibilities, ways the world might turn out to be, and to which value can be assigned. When, for example, people hope that God exists, or fear that we do not possess free will, they express attitudes towards these possibilities, attitudes that presuppose answers to questions about their comparative value. My aim in this paper is to distinguish these evaluative questions from related questions with which they can be confused, to identify structural constraints on their proper pursuit, and to address objections to their very coherence. Answers to such evaluative questions offer one measure of the importance of philosophical disputes.

    We often do not fully understand what lighting can do for us. We know that we need lighting, but often that is as far as the thinking goes. We do a really good job, however, of conceptualizing the costs of those lighting systems because we can readily measure those costs. Reducing costs will certainly increase the value ratio for lighting if the benefits of the lighting system are held constant. Without a clear purpose for the lighting system, and no clear idea of benefits, there is little else that can be used in the value engineering process.

    In this paper new Value at Risk (VaR) model is proposed and investigated. We consider the multifractal property of financial time series and develop a multifractal Value at Risk (MFVaR). MFVaR introduced in this paper is analytically tractable and not based on simulation. Empirical study showed that MFVaR can provide the more stable and accurate forecasting performance in volatile financial markets where large loss can be incurred. This implies that our multifractal VaR works well for the risk measurement of extreme credit events.

  18. Energy value as a factor of agroforestry wood species selectivity in Akinyele and Ido local government areas of Oyo State, Nigeria

    2009-10-15

    Wood usage for cooking and heating is still very relevant in most developing countries especially those of sub-Saharan Africa and many parts of Asia. Therefore, sustainable means of generating it for this and other purposes are necessary bearing in mind the influence of indigenous knowledge/users' perspective on any production method regarding success and sustenance. In conformity with this view, questionnaires were administered on 240 respondents in 8 rural communities of Akinyele and Ido Local Government Areas (LGAs) of Oyo State, Nigeria, to elicit information on species that can be used as fuelwood, preferred by the respondents for incorporation into and/or retention in agroforestry plots, out of which 179 (i.e. 75% of the total number of questionnaires administered) were successfully retrieved for statistical analyses. Twelve woody species namely: Annona senegalensis, Anogeissus leiocarpus, Bridelia ferruginea, Daniellia oliveri, Detarium microcarpum, Gardenia ternifolia, Hymenocardia acida, Lophira lanceolata, Parkia biglobosa, Terminalia avicennioides, Triplochiton scleroxylon and Vitellaria paradoxa were prioritized on the basis of respondents' preference using a ranking pattern. Friedman chi-square analysis showed that there was no significant difference (p < 0.05) in the ranking pattern of the respondents from the two LGAs. The mean net calorific values (NCV) of the 12 species were found to be 17.71, 18.63, 18.04, 16.03, 17.67, 18.46, 19.00, 21.68, 19.63, 18.25, 14.65, and 19.47 MJ kg{sup -1} respectively. The result of a two-way analysis of variance indicated a significant variation (p < 0.05) in NCV data for all the species pooled together but not for each species except for D. oliveri with a follow-up test using Fisher's Least Significant Difference. The Pearson's moment correlation analysis gave positive coefficient values (r = 0.868 and 0.874, p < 0.05) between NCV and the cumulative ranking values in Akinyele and Ido LGAs

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

    Full Text Available The People’s Republic of China (PRC is back on the global agenda. Inthe late 1970s, the process of modernization (reform and opening up under Deng Xiaoping brought enormous changes to the economy, society and cultural landscape. China has rapidly emerged as a major world power, despite the current global economic crisis. This article explores the changes in Chinese values caused by the expanding economic and cultural exchange processes within the country. Of specific theoretical interest is the role played by the mass media andinformation and communication technologies (ICT, and their bearing on modern Chinese society. Empirically, we first examine China’s placement on a global map of values (based on the World Value Survey, noting recent value shifts. We then offer a comprehensive view of attitudes of Chinese managers, drawing on a quantitative study from Beijing and Shanghai, to highlight the importance ofcultural differences deeply rooted in Chinese society. Finally, implications for cultural relations between West and East are discussed.

    Full Text Available The aim of this paper is to explore the relation between democratic values and emotions. The author argues that democratic values and emotional judgments are inter-reducible: political agents use emotional judgments to reflexively evaluate normative paradigms of political life. In the first part of the paper, the author describes the state of emotions in contemporary political philosophy and identifies Charles Stevenson’s ethical conception of emotivism as the first comprehensive attempt to neutrally conceptualize emotions in moral and political thinking. The second part of the paper explores the shortcomings of emotivism and finds an adequate alternative in Martha Nussbaum’s concept of emotional judgment as the one that contains beliefs and values about social objects. In the final part of the paper, the author identifies that moral and political disagreements emerge in democracies from ranking of the importance of political objects. The evaluation criteria for this type of ranking is derived from democratic values which are reducible to agents’ emotional judgments. [Projekat Ministarstva nauke Republike Srbije, br. 179076

    Full Text Available Management is responsible for its own financial decisions. If we take into account, that fair value concept was shown in financial crisis as something that does not work anymore in this way; there is a big need to develop it for the future. Non-professional readers of financial statements believe, however, that company financials are the work of the public accounting firm that had signed the audit certificate. The main reason for bringing this point up is that when companies disclose Fair Value (FV information in their financial statements, they are taking responsibility for the values disclosed. Management may often be encouraged to utilize the services of an outside professional, but at the end of the day, the outside appraiser is a hired gun. Although the appraiser has to take responsibility for his own work, hiring the appraiser does not absolve management of its ultimate responsibility. The obverse of this is also true. Management does not have to hire the appraiser to develop any fair value disclosures made in the financial statements. Developing FV information is not recommended as a do-it yourself undertaking, there is nothing in Generally Accepted Accounting Principles (GAAP or Securities Exchange Commission (SEC regulations, however, that requires an outside appraiser.

    Daniel Nascimento Pereira da Silva

    2011-12-01

    Full Text Available Brands have taken dominance in the strategies of enterprises once they are able to generate feelings, sensations and emotions in their clients. These values, value for the enterprises and for the brands themselves, are not measurable. A strong brand configures itself as the highest representative of an enterprise and the brand is regarded as an asset of the enterprise. The evolution of a brand, as an intangible and strategic asset, becomes more vitally important for the enterprises, as a way of maximizing the results. This need, whether of the market or the enterprises, justifies the direction of the research for this vector – the value of the brand. A main objective of the research is to present a new model of brand evaluation. This model is supported by a tangible and intangible aspects and the intangible aspect, evaluates the knowledge and capacity of their managers and workers to build a brand with value through the correct ordering of the priorities of the dimensions of the proposed model. The model was tested on the brand ‗Blue Rise.‘ 

  4. The polyphony of values and the value of polyphony

    Directory of Open Access Journals (Sweden)

    Lars Thøger CHRISTENSEN

    2015-07-01

    Full Text Available While human communication is inherently symbolic and thus potentially vague, ambiguous and polyphonic, there is a growing emphasis on certainty, accuracy and consistency in everything contemporary organizations say and do. Organizational messages about corporate values, in particular, are expected to accurately and unambiguously depict the organizational sender “behind” the words. Current communication principles, in other words, seek to reduce or eliminate the polyphonic potential of symbolic communication. In this paper we challenge this trend, arguing that the polyphony of corporate values is valuable because it facilitates change by inviting alternative interpretations and stimulating participation and critique. Lack of accuracy in organizational messages – including inconsistencies between what organizations say and what they do – may be an important driver of organizational and social change, because such differences have potential to raise expectations and apply pressure on organizational actors to improve their practices.

The study of non-alternating sums leads to an investigation of different types of sums which we call multiple Clausen values. The study of alternating sums leads to a tower of experimental results involving polylogarithms in the golden ratio. In the non-alternating case, there is a strong connection to polylogarithms of the sixth root of unity, encountered in the 3-loop Feynman diagrams of {\\tt hep-th/9803091} and subsequently in hep-ph/9910223, hep-ph/9910224, cond-mat/9911452 and hep-th/0004010.

    Full Text Available After clearing land by burning the peat, then the weeds and undergrowth will flourish. Even sometimes, the weeds are eventually burned again. Weed is known as a destroyer plant that has to be controlled. Through proper treatment, the existing weeds in peatlands can be potentiallly exploited. The purpose of this study was to determine the calorific value of briquettes as one of peatland weeds utilization. The results showed that the calorific value ranged from 2,492 cal/g to 5,230 cal/g. The lowest calorific value was on ‘teki kecil’ grass (Scirpus grossus Lf, while the highest calorific value was observed for ‘bantalaki grass’ (Hymenachne amplexicaulis Nees. The high calorific value of the peat weeds are potential for biomass briquettes raw materials. The utilization and use of peat weed briquettes as a raw materials expected can reduce land degradation due to peat swamp burning

  7. Value Assessment at the Point of Care: Incorporating Patient Values throughout Care Delivery and a Draft Taxonomy of Patient Values.

    Incorporation of patient values is a key element of patient-centered care, but consistent incorporation of patient values at the point of care is lacking. Shared decision making encourages incorporation of patient values in decision making, but associated tools often lack guidance on value assessment. In addition, focusing on patient values relating only to specific decisions misses an opportunity for a more holistic approach to value assessment that could impact other aspects of clinical encounters, including health care planning, communication, and stakeholder involvement. In this commentary, we propose a taxonomy of values underlying patient decision making and provide examples of how these impact provision of health care. The taxonomy describes four categories of patient values: global, decisional, situational, and external. Global values are personal values impacting decision making at a universal level and can include value traits and life priorities. Decisional values are the values traditionally conceptualized in decision making, including considerations such as efficacy, toxicity, quality of life, convenience, and cost. Situational values are values tied to a specific moment in time that modify patients' existing global and decisional values. Finally, discussion of external values acknowledges that many patients consider values other than their own when making decisions. Recognizing the breadth of values impacting patient decision making has implications for both overall health care delivery and shared decision making because value assessments focusing only on decisional values may miss important patient considerations. This draft taxonomy highlights different values impacting decision making and facilitates a more complete value assessment at the point of care.

    A number of individual personality factors and social norms may be associated with reproductive confusion and/or irresponsibility. More specifically, the values underlying common American social norms may contribute to ineffective birth planning in the following ways: 1) The traditional roles of women in our society seem to encourage parenthood. The rule has been early marriage, closely spaced children, and few alternate sources of satisfaction or self-esteem. 2) Our culture strongly encourages family life. Children are a symbol of normalcy. 3) The importance of sexual enjoyment per se often conflicts with contraceptive use. Conversely, innocence is also valued and also contributes to unprotected sexual activity. 4) Religious reasons or adherence to concepts of natural law are almost always given by people opposed to contraception. 5) Health is important to Americans, and birth control methods negatively affect health in real and imagined ways. Social norms, though changing, remain essentially congruent with former contraceptive technology and former ideologies, customs, and dreams.

Textile clusters are developing and patterns in cluster formations are emerging that reflect the differing economic conditions of the regions, demonstrating particular influences on the value chain. These differences are both depicted in the two regions of Kyrgyzstan-south and north. In the north of the Republic the infrastructure is more developed, there is greater facility to access international markets (exports. In the south the infrastructure is less developed, and garment producers in the region serve mainly local niche and near-neighbour markets. The research objective is to assess the key drivers of the value chain and profitability in the textiles sector in Kyrgyzstan, by comparing the garment sewing sector in the two contrasting regions of south and north Kyrgyzstan.

Twenty-first century professionals need a special training that enables them to venture into various branches of knowledge. Therefore, they must have an original thinking and innovation skills; they must be part of their training, take a dignified position in the social context they live in and be committed to its mission. The University, as a social institution, should include in their training models social problems and transformation processes, so that students learn and teachers teach with true meaning and significance. At university level, values education is centered in the practical teaching-learning process and is based on study and work. This problem needs to be analyzed from a specific historical approach on subject-object relationship. This work is aimed at socializing some theoretical and practical reflections on values education at the university as well as teacher's role in their formation from an instructive perspective.

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

  7. The Economic Value of Water

    Full Text Available The economic term of water is seen from the perspective of an ecological economy, an Aristotelian sense that integrates social values, environmental considerations and financial issues. Water should thus be conceptualized as an “ecosocial” good and not merely as a simple factor of production. Therefore, the focus of water management should not limit itself to managing a scarce resource. Rather the focus should be to articulate an institutional framework that would allow for the use of management tools based on the financial value of water (pricing policies, fiscal incentives, economic penalties for inefficiency... fixed to a somewhat interventionist market, or which answers to administration mechanisms, with constraints setting the conditions of sustainablity that the sound management of water requires in each territory. This approach brings to the table a profoundly territorial andcontextualized view of water management within the paradigm of Sustainable Development. Having said this does not imply disregarding the classical economic science tools of cost/benefit analysis, though. Quite the contrary: today, economic science can provide highly useful, multiple concepts and traditional techniques to the creation of a new model of the economic management of water. At bottom, the challenge is to take advantage of the previous conceptual and methodological body of work, refining the work in some cases,contextualizing it in others, and above all, complementing the previous work with other value-based perspectives to develop a multi-criteria decision-making model for the management and financial assessment of water policies.

  8. Value-based insurance design: embracing value over cost alone.

    2009-12-01

    The US healthcare system is in crisis, with documented gaps in quality, safety, access, and affordability. Many believe the solution to unsustainable cost increases is increased patient cost-sharing. From an overall cost perspective, reduced consumption of certain essential services may yield short-term savings but lead to worse health and markedly higher costs down the road--in complications, hospitalizations, and increased utilization. Value-based insurance design (VBID) can help plug the inherent shortfalls in "across-the-board" patient cost-sharing. Instead of focusing on cost or quality alone, VBID focuses on value, aligning the financial and nonfinancial incentives of the various stakeholders and complementing other current initiatives to improve quality and subdue costs, such as high-deductible consumer-directed health plans, pay-for-performance programs, and disease management. Mounting evidence, both peer-reviewed and empirical, indicates not only that VBID can be implemented, but also leads to desired changes in behavior. For all its documented successes and recognized promise, VBID is in its infancy and is not a panacea for the current healthcare crisis. However, the available research and documented experiences indicate that as an overall approach, and in its fully evolved and widely adopted form, VBID will promote a healthier population and therefore support cost-containment efforts by producing better health at any price point.

    Full Text Available The absence of the methods of urban analysis in the process of urban development of Yerevan is the reason of urban planning activities that tend to decrease the urban value of Yerevan territories. Meanwhile the studies in the sphere of urban planning and urban analysis prove the dependence of the life in the city on its structure and distribution of the functions. The mentioned issue highlights the importance of urban analysis. The paper discusses space syntax, which is one of the initial methods of urban analysis. The basic concept of Space syntax is based on the assumption that urban fabric can be presented and studied as a power graph. The method provides the measures that evaluate the land use, traffic and pedestrian movement, land value and even carbon emissions. The paper discusses also recent attempts of integration of space syntax method into GIS environment. GIS databases provide researchers with vast amount of urban data. Analyses presented in the current paper were performed on the basis of the open street map, which was imported from the GIS environment. With the application of space syntax methods analysis of connectivity, integration choice (betweenness and depth from the city center were performed to evaluate the structural value of Yerevan streets. Municipal regions of Yerevan were classified by the level of their accessibility and by their distances from the city center on the base of the results of depth measures from the city center. Evaluation of the street network aims to define the most integrated and centrally positioned parts of the city. These areas can be locations for the organization of sub centers of Yerevan in the municipal regions.

    During 2005, the Carbon Trust worked with Cairneagle Associates to develop a methodology for analysing shareholder value at risk from climate change. The model developed offers a robust, replicable, top-down approach to analysing such value at risk. In addition to a company's own energy linked ('direct' and electricity linked 'indirect') carbon emissions, it looks further along the value chain and considers broader potential risk. In calculating the financial impact, the analysis quantifies the potential impact on profits, using the shape of the business in 2004, but applying a potential 2013 emissions regulatory regime. 2013 was chosen as the first year after the end of the 2008-2012 Kyoto compliance period (which also equates to Phase Two in the EU Emissions Trading Scheme). A major uncertainty is to what extent countries not currently regulated by the Kyoto Protocol (particularly the USA, India and China) will be brought into committed emission reduction targets from 2013. 2013 therefore represents the earliest year under this uncertain, but likely tougher, regulatory regime. However, although this report focuses on 2013, it needs to be recognised that, for many sectors, financial impacts will be seen significantly before this time. Ten 'case study companies' have been studied, from a range of sectors. In some cases, the 'case study company' analysed is strictly linked to a single company within that sector. In others, just a single corporate division has been reviewed, and in others yet again, characteristics from several companies have been combined to produce a more representative example. In order to enable analysis on a strictly like-for-like basis, the research has been based entirely upon public sources of information. This analysis illustrates what a determined shareholder (or other onlooker) could derive about value at risk from climate change, based upon what companies disclose today. A summary of the

The method extends to Dirichlet L-functions and our estimates appear to be partly related to earlier investigations surrounding Li's criterion for the Riemann hypothesis.

    1976-11-01

    Attitudes and values in medicine vary with the nature of the individual, his education and training, and the circumstances of his professional life. Comparisons are drawn between medical education in Britain 40 years ago and today. Though education has changed, British students are still mainly motivated by a desire to care for sick people. The impact of personal medicine on a country that has long accepted the need for some kind of national health service is described. It is postulated that as government and public become increasingly involved in health care, it is of paramount importance that medical education should provide a clear understanding of what a profession is and inculcate a determination to maintain true professional status. New responsibilities of the profession, to the public at large and to society, are suggested. The ability of medical education to exert a good influence on concern for human values in medicine depends in the final analysis on the ability to show excellence to medical students.

  20. Economic Values and Resource Use

    Directory of Open Access Journals (Sweden)

    Jan Mikael Malmaeus

    2016-05-01

    Full Text Available Absolute decoupling of GDP growth from resource use implies that economic output can be increased without simultaneously increasing input. The essential meaning of this proposition is that the economic values that represent the GDP can be realized by increasing resource efficiency. Given that the GDP is first and foremost a measure of economic activity rather than welfare the possibility of absolute decoupling is theoretically limited. This paper demonstrates theoretically and empirically that economic values at the macroeconomic level are fundamentally determined by the use of production factors, primarily labor and physical capital. Technical innovations or efficiency gains increasing utility without raising the costs of production do not add to the GDP unless they stimulate investments in physical capital. Hence the neoclassical notion of productivity is only found to be relevant as a microeconomic concept. In practice, GDP growth is mostly explained by capital accumulation and a key question is whether or not capital accumulation can be decoupled from the use of materials and energy. This will determine the possibility of decoupling of GDP growth from resource use and environmental impact. Alternative measures of progress focusing on welfare rather than economic activity are more likely to achieve absolute decoupling.

    Teamwork, partnership and shared values emerged as recurring themes at the Third Technology Transfer/Communications Conference. The program drew about 100 participants who sat through a packed two days to find ways for their laboratories and facilities to better help American business and the economy. Co-hosts were the Lawrence Livermore National Laboratory and the Lawrence Berkeley Laboratory, where most meetings took place. The conference followed traditions established at the First Technology Transfer/Communications Conference, conceived of and hosted by the Pacific Northwest Laboratory in May 1992 in Richmond, Washington, and the second conference, hosted by the National Renewable Energy Laboratory in January 1993 in Golden, Colorado. As at the other conferences, participants at the third session represented the fields of technology transfer, public affairs and communications. They came from Department of Energy headquarters and DOE offices, laboratories and production facilities. Continued in this report are keynote address; panel discussion; workshops; and presentations in technology transfer.

    Raw kerogen oil is rich in heteroatom-containing compounds. Heteroatoms, N, S & O, are undesirable as components of a refinery feedstock, but are the basis for product value in agrochemicals, pharmaceuticals, surfactants, solvents, polymers, and a host of industrial materials. An economically viable, technologically feasible process scheme was developed in this research that promises to enhance the economics of oil shale development, both in the US and elsewhere in the world, in particular Estonia. Products will compete in existing markets for products now manufactured by costly synthesis routes. A premium petroleum refinery feedstock is also produced. The technology is now ready for pilot plant engineering studies and is likely to play an important role in developing a US oil shale industry.

  4. The Value of Clean Air

    Shindell, D. T.

    2014-12-01

    How can society place a value on clean air? I present a multi-impact economic valuation framework called the Social Cost of Atmospheric Release (SCAR) that extends the Social Cost of Carbon (SCC) used previously for carbon dioxide (CO2) to a broader range of pollutants and impacts. Values consistently incorporate health impacts of air quality along with climate damages. The latter include damages associated with aerosol-induced hydrologic cycle changes that lead to net climate benefits when reducing cooling aerosols. Evaluating a 1% reduction in current global emissions, benefits with a high discount rate are greatest for reductions of co-emitted products of incomplete combustion (PIC), followed by sulfur dioxide (SO2), nitrogen oxides (NOx) and then CO2, ammonia and methane. With a low discount rate, benefits are greatest for CO2 reductions, though the sum of SO2, PIC and methane is substantially larger. These results suggest that efforts to mitigate atmosphere-related environmental damages should target a broad set of emissions including CO2, methane and aerosol/ozone precursors. Illustrative calculations indicate environmental damages are 410-1100 billion yr-1 for current US electricity generation ( 19-46¢ per kWh for coal, 4-24¢ for gas) and 3.80 (-1.80/+2.10) per gallon of gasoline ($4.80 (-3.10/+3.50) per gallon for diesel). These results suggest that total atmosphere-related environmental damages plus generation costs are much greater for coal-fired power than other types of electricity generation, and that damages associated with gasoline vehicles substantially exceed those for electric vehicles.

    Modeling a business to match its customer perceived (and customer desired) outcomes, remains an on-going task. This paper considers shows how a service value networks (SVNs) approach may be engaged to model, and deliver, understanding of the front-end business and its direct engagement with its immediate (or front-end) customers. These front-end customers may be either: (1) its off-line,in-store customers - engaging directly with the business sales staff (or representative), or- (2) its on-line, virtual customers - engaging with the business via internet or remote access. In this situation,both the business, and the customer draw upon their respective viewpoints, and both sides influence the interaction. External to these business and customer influences are additional factors that capture the immediate and broader global effects - termed environmental effects. These three business-customer engagement areas of influence are captured by a SVN SEM approach.Without a business-customer encounter of some kind the likelihood of a services business, and a prospecting customer, successfully engaging in an exchange process is reduced. This exchange may be a physical, and/or services exchange, and/or an information and/or ideas exchange. To the business,this encounter is, in effect, a trade, and as a result, the business targets acquiring an economic exchange that will ultimately deliver a net positive economic outcome. To the customer, external and internal information feeds, servicing, perceived value, and satisfaction, are key encounter drivers.SVNs offers a new way to understand the business-customer encounter, and to then utilize this acquired knowledge to either: (1) build a strategic management model, or (2) reengineer its business networks, and to then create a re-positioned, more customer-aligned business operation - one that is capable of delivering win - win, competitive business-customer solutions.

  6. Do We Really Value Learning?

    Science.gov (United States)

    Moore, John W.

    1999-01-01

    University faculty think of their institutions as places in which learning is valued and pride themselves on the discovery of new knowledge. Indeed universities have been unusually successful in supporting research and developing new knowledge that has been enormously beneficial to society, and university faculty value learning far more than the average. But some kinds of learning are more valued than others-a fact that I believe is detrimental to the long-term welfare of both universities and society. By far the most valued learning is by someone who discovers what nobody else has learned before. We call the process of achieving such learning "research". It is the coin of the academic realm, at least partly because it is easy to evaluate. Those who do it creatively can reap the rewards of respect from their colleagues, better facilities and instrumentation from their institutions, regional and national awards from their disciplinary societies, and increased funding from government and industry for their endeavors. Significantly less valued are activities that help others to learn, especially when the learning involves things already known by many. We call such activities "teaching", although the dictionary definition of "teach" ("to show how to do something; give instructions to; train") is not broad enough to encompass the range of activities currently being used to encourage learning. There is a widespread notion that teaching is easy and requires no real creativity. Nontenured faculty are often warned that time spent on teaching will be thought of as "wasted", and those well established in research have been criticized for spending too much of their time on the "unproductive" activity of teaching. Teaching is held out to students as a fall-back position in case their other career plans do not pan out, and sometimes those who educate teachers are willing to accept less than the highest quality from the students to whom they provide credentials. Those who employ

    wetland habitats throughout their annual cycles. Survival, reproduction, and growth are dependent on the availability of foods that meet nutritional requirements for recurring biological events. These requirements occur among a wide variety of environmental conditions that also influence nutritional demands. Recent work on nesting waterfowl has identified the female’s general nutrient needs for egg laying and incubation. Far less is known about nutritional requirements for molt and other portions of the life cycle, particularly those during the nonbreeding season. Although information on specific requirements for amino acids and micronutrients of wild birds is meager, the available information on waterfowl requirements can be used to develop waterfowl management strategies. For example, nutrient content of foods, nutritional requirements of waterfowl, and the cues waterfowl use in locating and selecting foods are all kinds of information that managers need to encourage use of habitats by feeding waterfowl. Waterfowl nutritional needs during the annual cycle and the nutritional values of natural foods and crops will be discussed below.

    Full Text Available A new approach to interpreting the landscape is examined by accepting its complexity through inductive reasoning. While attempting to identify the essence of the landscape in the city and municipality of Óbidos, Portugal, several architectural recommendations of Venturi (2004 have been adapted as a framework for understanding this landscape. These will then guide the process of landscape transformation through:•••using the concepts of closed and contained spaces and the concept of fluid space;•recognising the existence of interstitial open spaces;•using those elements which are common to the distinct typologies of space;•defining the components that should be respected and those that can be respected;•observing landscape as a whole , while emphasising the relationship between the parts and the whole; and•rejecting simplification in the landscape transformation process.valuing the ambiguity incorporating the complexity Underlying this approach is the belief that the process of transformation must be based on the essence of each landscape. This implies the use of elements and structures of the landscape which are related to ecological, morphological and cultural systems. These elements and structures represent points of reference which should be considered in the process of landscape transformation.

    Full Text Available Many parts of the world now swim in a sea of complex products that do not necessarily improve the overall quality of our lives. From cell phones to baby strollers, we have overloaded our designed environment with hyper-functional products that often leave us searching for simpler, straighter forward product offerings. In a product landscape that more often than not equates complexity with sophistication; our ever-increasingly complex modern society has allowed faux conveniences to outweigh the tangible realness of our experiences. The look and feel of products has often become complex and complicated – and this is often highlighted as a positive thing. We are less likely to encounter simple, intuitive, and usable products geared toward the individual. To avoid this trap, one would need to apply a filter that would govern the intake of certain products to only those that are seen as adding true value to our lives. It is necessary to appeal to people’s emotions, and carry cultural richness and authenticity back to the forefront while embracing the power of cur-rent and future technologies. Design has tremendous power and the versatility necessary to bring about this positive change.

  12. Values and education: Russian perspective

    Directory of Open Access Journals (Sweden)

    Borytko Nikolai M.

    2005-01-01

    Full Text Available This article is about some lessons of the multi-cultural analysis of a joint Russian-British educational project. The analysis, based on the achievements of Russian pedagogical science, about the achievement of the most effective cross-cultural communication, can be listed among the outcomes of the project, along with the applied results, which consists in developing an educational management training program. The growth of innovation process and international contacts in education testifies to the fact that education culture is evolving toward a new quality. In the evolution/process, the basic needs of schools, teachers and education managers are identified and conceptualized. Sharing achievements and discoveries in professional growth should be kept in mind and that fulfilling the needs can only take place within the context of the cultural-pedagogic position inherent to an individual teacher, a group of teachers, or a school. From the point of view of cross-cultural analysis, the specifics lie in the inherent values and the level at which the activity is typically performed. This analysis equips the researcher with the criteria necessary for identifying the culture type dealt with. This latter can be used then as a tool for analyzing and designing innovations.

    2016-07-01

    Value-based healthcare models are being adopted globally to maximize value for patients. Given that procurement is at the heart of purchasing value, value-based procurement goes hand in hand with value-based healthcare. Shifting procurement's traditional focus on short-term cost savings to a more holistic objective that includes health system performance and patient outcomes, giving preference to longer-term cost efficiencies, and working with suppliers to identify opportunities to develop more innovative products and services, is proving successful in leading jurisdictions. This article presents an overview of value within healthcare systems and how healthcare value-based procurement is being implemented across various jurisdictions.

    2008-01-01

    The customer value, the key problem in customer relationship management (CRM), was studied to construct a gap model for dual customer values. A basic description of customer values is given, and then the gaps between products and services in different periods for the customers and companies are analyzed based on the product or service life-cycle. The main factors that influence the perceived customer value were analyzed to define the "recognized value gap" and a gap model for the dual customer values was constructed to supply companies with a tool to analyze existing customer value gaps and improve customer relationship management.

    Full Text Available The revised Personal Values Scale now consists of 24 values, representing 24 basic human motives. It was given to 595 students and adults. Relations among values were analysed by techniques of multivariate analysis. The results show that, despite of weak intercorrelations among personal values, the values space is structured by two bipolar values macrodimensions (dionisian–apolinian, existential–fulfillment and that also clusters of narrow range exist. The results were discussed and compared with Musek's structure model. A new model of personal values is presented.

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

    A new kind of vector valued rational interpolants is established by means of Samelson inverse, with scalar numerator and vector valued denominator. It is essen tially different from that of Graves-Morris(1983), where the interpolants are constructed by Thiele-type continued fractions with vector valued numerator and scalar denominator. The new approach is more suitable to calculate the value of a vector valued function for a given point. And an error formula is also given and proven.

    2012-10-01

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

    Science.gov (United States)

    Anderson, J C; Narus, J A

    1998-01-01

    How do you define the value of your market offering? Can you measure it? Few suppliers in business markets are able to answer those questions, and yet the ability to pinpoint the value of a product or service for one's customers has never been more important. By creating and using what the authors call customer value models, suppliers are able to figure out exactly what their offerings are worth to customers. Field value assessments--the most commonly used method for building customer value models--call for suppliers to gather data about their customers firsthand whenever possible. Through these assessments, a supplier can build a value model for an individual customer or for a market segment, drawing on data gathered form several customers in that segment. Suppliers can use customer value models to create competitive advantage in several ways. First, they can capitalize on the inevitable variation in customers' requirements by providing flexible market offerings. Second, they can use value models to demonstrate how a new product or service they are offering will provide greater value. Third, they can use their knowledge of how their market offerings specifically deliver value to craft persuasive value propositions. And fourth, they can use value models to provide evidence to customers of their accomplishments. Doing business based on value delivered gives companies the means to get an equitable return for their efforts. Once suppliers truly understand value, they will be able to realize the benefits of measuring and monitoring it for their customers.

  20. MODELING A VALUE CHAIN IN PUBLIC SECTOR

    Directory of Open Access Journals (Sweden)

    Daiva Rapcevičienė

    2014-08-01

    Full Text Available Purpose – Over the past three decades comprehensive insights were made in order to design and manage the value chain. A lot of scholars discuss differences between private sector value chain – creation profit for the business and public sector value chain, the approach that public sector creates value through the services that it provides. However, there is a lack of a common understanding of what public sector value chain is in general. This paper reviews the literature on how the private value chain was transformed into public value chain and reviews a determination and architecture of a value chain in public sector which gives a structural approach to greater picture of how all structure works. It reviews an approach that the value chain for the public sector shows how the public sector organizes itself to ensure it is of value to the citizens. Design/methodology/approach – descriptive method, analysis of scientific literature. Findings – The public sector value chain is an adaptation of the private sector value chain. The difference between the two is that the customer is the focus of the public sector context, versus the profit focus in the private sector context. There are significant similarities between the two chain models. Each of the chain models are founded on a series of core components. For the public sector context, the core components are people, service and trust. Research limitations/implications – this paper based on presenting value chain for both private and public sectors and giving deeper knowledge for public sector value chain model. Practical implications – comprehension of general value chain model concept and public sector value chain model helps to see multiple connections throughout the entire process: from the beginning to the end. The paper presents the theoretical framework for further study of the value chain model for waste management creation. Originality/Value – The paper reveals the systematic

  1. CONSUMERS PRODUCTS AND SERVICES VALUE PERCEPTION

    Directory of Open Access Journals (Sweden)

    Bogdan Nichifor

    2008-12-01

    Full Text Available This article is a theoretical approach on products and services as value satisfiers. Consumers have knowledge about the personal, symbolic values that products, services and brands help them satisfy or achieve. Values are people’s broad life goals. Values often involve the emotional affect associated with such goals and needs (the strong feelings and emotions that accompany success. Recognizing when a value has been satisfied or a basic life goal has been achieved is an internal feeling that is somewhat intangible and subjective. In contrast, functional and psychosocial consequences are more tangible and are more obvious when they occur. Salespeople add value by identifying customer needs and devising or delivering a solution for those needs. Salespeople are able to adapt how products or/and services are presented or even to adapt products/services so that they meet the needs of the buyers. Such adaption powers professional selling, because customers often don’t know what they need or how to configure a solution to their needs. Satisfying a value usually elicits positive affect (happiness, joy, satisfaction, whereas blocking a value produces negative affect (frustration, anger, disappointment. Consumers can have products and services knowledge about products and services attributes, consequences of products or services use and personal values. Most marketing research focuses on one type of products and services knowledge – usually attributes or consequences, where the focus typically is on benefits rather than risks. Values are examined less frequently and usually in isolation. This paper objective is to show the importance of creating, delivering, and capturing buyer value. A company’s ability to deliver value to its customers is closely tied with its ability to create satisfaction for its employees and other stakeholders. Value ultimately depends on the perceiver. Smart companies not only offer purchase value but also offer use value

    2012-01-01

    Full Text Available This paper shows how to obtain the values of the numerator and denominator Kharitonov polynomials of an interval plant from its value set at a given frequency. Moreover, it is proven that given a value set, all the assigned polynomials of the vertices can be determined if and only if there is a complete edge or a complete arc lying on a quadrant. This algorithm is nonconservative in the sense that if the value-set boundary of an interval plant is exactly known, and particularly its vertices, then the Kharitonov rectangles are exactly those used to obtain these value sets.

    Full Text Available A common feature of our age is orientation of young people towards transitional values. Economic partnership of consumer society has a direct impact on values of society and even if the process of change of values can be affected by formers of education politics, economists and politicians, young people still choose values, which conform with their own lifestyle. Content of educational subjects is connected with study, succession of cultural values, study of classified knowledge and skills, which is also a prerequisite of formation of personality. Societies of all ages has formed according to the specific mechanism, accumulating and integrating general, notable at that time ideas, preserving and transforming their own social experience to the next generations. Each culture declares itself from its scale of values and norms. Priority of change of post material and material values changes together with conditions of cultural, historical and social-political life. Change of paradigms is change of viewpoint of the world, therefore conditions of value choice relate not only to separate groups, but to whole cultures. Young people, similar to other members of society, are forced to construct their own identity and to form their own life insurance strategies offered by the consumer society. Consumer society forms its values and it is creator of its own significance, but young people as social agents are reproducers of values of consumer society. Research results of World Value Surveys (WVS from six continents discovered big differences in value priorities between younger and older generations, which indicates not only inter-generation value change, but also changes in the whole society. The research “Value choice of young people in consumer society” in our country shows, that although the lifestyle of young people is pragmatic, traditional value – family is also one of the most often mentioned and important values in consumer society.

  6. Reflections on the value concept in accounting

    Directory of Open Access Journals (Sweden)

    P. Buys

    2009-07-01

    Full Text Available The recent meltdown in global finances and the reasons for it may make people doubtful about the stewardship function of accounting. In the global financial markets, there is a great fascination with the reality that accounting values intend to reflect. However, what many people considered valuable is now suddenly of no value. The question can therefore be asked what is meant by the value concept as a foundation to modern-day accountancy. “Value” is a concept that is open to different interpretations, based on the needs, perspectives and personal values of the interpreter. This article aims to reflect on the value concept from an accounting perspective in analysing the fundamental quali-tative perspectives and how these perspectives might affect the quantitative value measurements, as reported in the financial statements. From a quantitative perspective, accounttancy aims to measure and report the monetary values of items. However, there is a move towards a mixed valuation model with many financial statements, including both historical cost and value-based accounting information. The article concludes that this questionable development opens up many additional and subjective interpretations of accounting value measurement and reporting. Both valuation measurement methods have merit when considered in the overall purpose of accounting information. However, subjective value-based mea-surements may cast a shadow of doubt on the reliability and comparability requirements of accounting value information.

  7. On nonepistemic values in conservation biology.

    Science.gov (United States)

    Baumgaertner, Bert; Holthuijzen, Wieteke

    2017-02-01

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

  8. Evaluation of Kolubara lignite carbon emission characteristics

    Bakić Vukman V.

    2012-01-01

    Full Text Available The revised Intergovernmental Panel on Climate Change (IPCC guidelines for national greenhouse gas (GHG inventories recommends that more comprehensive and thus more reliable characteristics of the local fossil fuels should be used for the national GHG inventory calculations. This paper deal with the carbon emission characteristics of low-calorific lignite recovered from the Kolubara open-pit mine. The samples of coal were carefully selected in order to cover the net calorific value, ash and water content of the broad spectrum of the quality of the raw lignite supplied to the Serbian thermal power plants. Correlation analysis of the laboratory analysis data gave a linear dependency of the net calorific value on the combustible content in the coal samples. Also, linear correlation between the carbon content and the net calorific value was found. The regression analysis of experimentally determined coal characteristics implies that the carbon emission factor is dependent on the net calorific value. For the subset of raw lignite samples with the net calorific value Qdr = 6 ÷ 10 MJ/kg, that is most representative for current and near future use for power generation in Serbian thermal power plants, the linear dependency CEFr (tC/TJ = 34.407 - 0.5891×Qdr (MJ/kg was proposed. Regarding the net calorific ranges of samples examined, the raw Kolubara lignite carbon emission factor is considerably higher than those recommended by IPCC Tier 1 method of 27.6 tC/TJ.

    2006-01-01

    The collection of all the rough sets of an approximation space has been given several algebraic interpretations, including Stone algebras, regular double Stone algebras, semi-simple Nelson algebras, pre-rough algebras and 3-valued Lukasiewicz algebras. A 3-valued Lukasiewicz algebra is a Stone algebra, a regular double Stone algebra, a semi-simple Nelson algebra, a pre-rough algebra. Thus, we call the algebra constructed by the collection of rough sets of an approximation space a rough 3-valued Lukasiewicz algebra. In this paper,the rough 3-valued Lukasiewicz algebras, which are a special kind of 3-valued Lukasiewicz algebras, are studied. Whether the rough 3-valued Lukasiewicz algebra is a axled 3-valued Lukasiewicz algebra is examined.

    Sica, John R; Caswell, Michael

    2015-01-01

    Sun protection factor, SPF, is a measure of the efficacy of a topical sunscreen product; the higher the SPF, the greater the blockage of ultraviolet-induced erythema. While there are several methods to determine SPF, the Food and Drug Administration (FDA) methods are unique. The FDA methods define the label SPF value as the largest whole integer after subtracting an "A" value from the mean SPF. The A value, composed of the product of the upper 5% point of the t-distribution and the standard deviation (SD), divided by √(n), where n equals the number of subjects, has a significant impact on the label SPF value. Two examples explore this impact. Development of strategies to mitigate the impact of A using expected SPF values are explored using historical clinical trial data. A more enlightened choice of expected SPF values is shown to lead to higher label SPF values.

    Full Text Available The paper concentrates on the value premium across countries and contributes to the investment and asset pricing literature in three ways. First, I provide fresh evidence that the high-value countries perform significantly better than the low-value countries. Additionally, this phenomenon is indifferent to the choice of the computational currency, representative index or value indicator. Second, I demonstrate that the value effect can be successfully amplified by combining with country-level size and momentum effects. Third, I show that returns to the high-value countries deteriorate in financial crisis conditions, because the country-level value premium is negatively correlated with the credit spreads, TED spread and expected volatility. I examine data from 66 markets between years 2000 and 2013.

    Feminist standpoint empiricism contributes to the criticism of the value-free ideal by offering a unique analysis of how non-epistemic values can play not only a legitimate but also an epistemically productive role in science. While the inductive risk argument focuses on the role of non-epistemic values in the acceptance of hypotheses, standpoint empiricism focuses on the role of non-epistemic values in the production of evidence. And while many other analyses of values in science focus on the role of non-epistemic values either in an individual scientist's decision making or in the distribution of research efforts in scientific communities, standpoint empiricism focuses on the role of non-epistemic values in the building of scientific/intellectual movements.

    Full Text Available Being value based is one of the principles project management has to respect in order to be sustainable. Values are guidelines for human behavior that are shared by a large group of individuals. As projects can be differentiated from investments, also projects’ values can be differentiated from investments’ values. Connecting projects with investments’ values contributes to projects’ success, to a sustainable project management process and to a sustainable investment. The article explains the differences between investments and projects and presents how the investment’s values can be related to the project. The topic is applicable when dealing with projects in general and can have benefic effects on investments initialized through projects financed by the European Union.

    Zacharopoulos, George; Lancaster, Thomas M; Maio, Gregory R; Linden, David E J

    2016-04-01

    Human values and personality have been shown to share genetic variance in twin studies. However, there is a lack of evidence about the genetic components of this association. This study examined the interplay between genes, values and personality in the case of neuroticism, because polygenic scores were available for this personality trait. First, we replicated prior evidence of a positive association between the polygenic neuroticism score (PNS) and neuroticism. Second, we found that the PNS was significantly associated with the whole human value space in a sinusoidal waveform that was consistent with Schwartz's circular model of human values. These results suggest that it is useful to consider human values in the analyses of genetic contributions to personality traits. They also pave the way for an investigation of the biological mechanisms contributing to human value orientations.

    In construction projects the client will comprise both owner, end-users, and the wider society, representatives of which may have conflicting goals and values; and these may not be fully realized by the stakeholders themselves. Therefore it is a great challenge to capture and manage the values...... of the multiple stakeholders that constitutes the “client”. However, seeing client satisfaction as the end-goal of construction it is imperative to make client values explicit in the early project phase and make sure that these values are reflected in all subsequent phases of design and construction....... The management challenge is further complicated by the fact that the delivery team, who are to understand and deliver client value, consists of even more different parties. To address this a Danish engineering consultancy company has, together with a major contractor, developed a value-based workshop method...

    2005-07-01

    A general guide for all generators connected to the electric power distribution network is presented. It provides an indication of the tradable value of distributed generation in prevailing market conditions. The document covers (i) the elements of value for which distributed generators may be awarded; (ii) how generators can realize these values and (iii) references to other relevant sources of information. The value an individual generator can realize depends on size, technology, operating profile, location and connection voltage. Definitions of small, medium and large generators are given. The values received by a generator will depend at least on prevailing prices, time of day and time of year. Added value may come from Renewable Obligation Certificates and Climate Change Levy Exemption Certificates. Worked examples are given for a domestic PV system, an industrial CHP scheme and a wind farm. The study was carried out by Ilex Energy Consulting and supported by the DTI.

  19. The use of the white poplar (Populus alba L.) biomass as fuel

    Institute of Scientific and Technical Information of China (English)

    Tatiana Griu; Aurel Lunguleasa

    2016-01-01

    We determined the calorific value of white poplar (Populus alba L.) woody biomass to use it as fire-wood. The value of 19.133 MJ kg-1 obtained experimen-tally shows that the white poplar can be quite successfully used as firewood. Being of a lower quality in comparison with usual beech firewood, the white poplar has similar calorific value. The white poplar has a calorific density of 30.7%lower than that of current firewood. That is why the price of this firewood from white poplar is lower accord-ingly. Also, the prognosis of calorific value on the basis of the main chemical elements, being very close to the experimental value (?2.6%), indicates an appropriate value can be achieved to be used for investigation with the chemical element analysis.

    Many existing industrial and research data sets contain missing values due to various reasons, such as manual data entry procedures, equipment errors and incorrect measurements. Problems associated with missing values are loss of efficiency, complications in handling and analyzing the data and bias resulting from differences between missing and complete data. The important factor for selection of approach to missing values is missing data mechanism. There are various strategies for dealing wi...

    A novel learning method for multi-valued associative memory network is introduced, which is based on Hebb rule, but utilizes more information. According to the current probe vector, the connection weights matrix could be chosen dynamically. Double-valued and multi-valued associative memory are all realized in our simulation experiment. The experimental results show that the method could enhance the associative success rate.

  4. The Values System in the Franchising Entrepreneurship

    Konstantopoulos, Nikolaos; Tomaras, Petros; Zondiros, Dimitrios

    2007-12-01

    This paper examines the values system delimiting the entrepreneurial activity. The total of these entrepreneurial activities is defined within the franchising framework. The reason for choosing to examine these activities is that franchising is considered to be a rather special kind of entrepreneurship. By this way, it can be examined whether specific entrepreneurial values are required in order to turn to franchising, or it concerns a strategic entrepreneurial choice which is independent from the value standards.

  5. Possible values of UV index in Serbia

    2008-01-01

    Full Text Available INTRODUCTION UV Index is an indicator of human exposure to solar ultraviolet (UV rays. The numerical values of the UV Index range from 1-11 and above. There are three levels of protection against UV radiation; low values of the UV Index - protection is not required, medium values of the UV Index - protection is recommended and high values of the UV Index - protection is obligatory. The value of the UV Index primarily depends on the elevation of the sun and total ozone column. OBJECTIVE The aim of the study is to determine the intervals of possible maximal annual values of the UV Index in Serbia in order to determine the necessary level of protection in a simple manner. METHOD For maximal and minimal expected values of total column ozone and for maximal elevation of the sun, the value of the UV Index was determined for each month in the Northern and Southern parts of Serbia. These values were compared with the forecast of the UV Index. RESULTS Maximal clear sky values of the UV Index in Serbia for altitudes up to 500m in May, June, July and August can be 9 or even 10, and not less than 5 or 6. During November, December, January and February the UV Index can be 4 at most. During March, April, September and October the expected values of the UV Index are maximally 7 and not less than 3. The forecast of the UV Index is within these limits in 98% of comparisons. CONCLUSION The described method of determination of possible UV Index values showed a high agreement with forecasts. The obtained results can be used for general recommendations in the protection against UV radiation.

    The need to finance high growth and manage the interests and needs of investors makes value creation a critical concern for entrepreneurial businesses. Almost any financial endeavor, such as attracting new investors or making investment decisions, necessitates the consideration of the equity value created by the endeavor. The perceived value creation, for example, has a direct effect on the percentage of the firm outside investors will require if they are to invest in the business. Measuring ...

  7. Population change and socio-cultural values.

    Science.gov (United States)

    1982-06-01

    The developing countries of the world in general, and those of Asia and the Pacific in particular, recognize that unplanned population growth is a stumbling block to socioeconomic development. Discussion here focuses on population growth and social, economic, and institutional forces, which are referred to as sociocultural values. Generally, sociocultural values change sluggishly over time. The rate at which a country's sociocultural values change depends on several factors such as the stage of economic development and modernization and whether a country has an open or closed door policy. "The Value of Children Study: A Crossnational Study" by Fred Arnold et al. shows that there are positive and negative values attributed to children in the Asian countries. These are: positive general values--emotional benefits, economic benefits and security, self enrichment and development, identification with children, and family cohesiveness and continuity; negative general values--emotional costs, economic costs, restrictions on opportunity costs, physical demands, and family costs; large family values--sibling relationships, sex preferences, child survival; and small family values--maternal health and societal costs. Possibly the most formidable obstacle to the success of antinatalist population policies is that of religious values. It appears that the Muslim world is divided on the issue of fertility control. Conflicting views regarding fertility control is perhaps aggravated by the fact that there is no central international religious official hierarchy that issues out edicts. Despite the presence of a centralized religious hierarchy and a network of churches from the Vatican to the village levels among the Catholics, and a clearer elucidation of the Humanae Vitae, a liberal attitude to population regulation and family planning has emerged, largely because of the declining quality of life of the people resulting from unplanned births. Economic benefits of children include

    2013-01-01

    To expand the information of nest individuals, the idea of complex-valued encoding is used in cuckoo search (PCS); the gene of individuals is denoted by plurality, so a diploid swarm is structured by a sequence plurality. The value of independent variables for objective function is determined by modules, and a sign of them is determined by angles. The position of nest is divided into two parts, namely, real part gene and imaginary gene. The updating relation of complex-valued swarm is presented. Six typical functions are tested. The results are compared with cuckoo search based on real-valued encoding; the usefulness of the proposed algorithm is verified.

    1994-12-01

    On the basis of Herzberg, Mausner, and Snyderman's (1959) motivator-hygiene theory, it was hypothesized that intrinsic but not extrinsic work values would be inversely related to stress. Also investigated was the question of which work values provide the most relief from stress. Elementary school teachers and administrators (N = 607) from nine school boards in southern Ontario completed a survey that included Pines, Aronson, and Kafry's (1981) stress scale and Elizur's (1984) work values scale. Almost all of the 12 intrinsic work values investigated were negatively correlated with stress, but the 4 extrinsic work values studied were not consistently related to stress. Five work values explained 11% of the variance in physical stress, 9 work values explained 22% of the variance in emotional stress, and 6 work values explained 26% of the variance in mental stress. Four work values emerged as meaningful predictors of all three types of stress: being esteemed by others, achieving through work, doing meaningful work, and being able to use one's knowledge and abilities.

    James Griffin has considered a weak form of superiority in value a possible remedy to the Repugnant Conclusion. In this paper, I demonstrate that, in a context where value is additive, this weaker form collapses into a stronger form of superiority. And in a context where value is non-additive, weak...... superiority does not amount to a radical value difference at all. I then spell out the consequences of these results for different interpretations of Griffin's suggestion regarding population ethics. None of them comes out very successful, but perhaps they nevertheless retain some interest....

    This paper analyzes assumptions that are implicitly made in updating estimates of nominal values for environmental goods produced by previous valuation studies, especially adjustments made through use of the consumer price index (CPI). The paper illustrates that the underlying form of preferences for the selected values from a past study may have a significant influence on the updated environmental values. We show why care is necessary in updating past welfare or value estimates in the face of changes in the demand and supply for environmental amenities when using the CPI.

    2016-02-01

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

    Institute of Scientific and Technical Information of China (English)

    Germanno Resconi

    2006-01-01

    In fuzzy set theory, instead of the underlying membership set being a two -valued set it is a multi-valued set that generally has the structure of a lattice L with a minimal element O and the maximal element I. Furthermore if ∧, ∨, → and (「) are defined in the set L, then we can use these operations to define, as in the ordinary set theory, operations on fuzzy subsets. In this paper we give a model of the Lattice-Valued Logic with set of agents.Any agents know the logic value of a sentence p. The logic value is compatible with all of the accessible conceptual models or worlds of p inside the agent. Agent can be rational or irrational in the use of the logic operation.Every agent of n agents can have the same set of conceptual models for p and know the same logic for p in this case the agents form a consistent group of agents.When agents have different conceptual models for p,different subgroup of agents know different logic value for p. In this case the n agents are inconsistent in the expression of the logic value for p. The valuation structure of set of agents can be used as a semantic model for the Lattice-valued Logic and fuzzy logic.

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

    In this essay, a quintet of values in doing philosophy of music education are examined: the need for a broad view, a personal perspective, a constructive vision, a relevant plan, and the courage to speak about important issues in music education. The following questions frame the analysis of each, in turn: What do these values mean? What…

    Every truth-functional three-valued propositional logic can be conservatively translated into the modal logic S5. We prove this claim constructively in two steps. First, we define a Translation Manual that converts any propositional formula of any three-valued logic into a modal formula. Second, we

    Placing a monetary value on education is a complex task. A more difficult task is to determine at what monetary level individuals will support educational improvements. The contingent valuation method was used to estimate the value of the implementation of financial literacy education in Texas public schools. A Web-based survey was administered to…

    We consider approximating the minmax value of a multi player game in strategic form. Tightening recent bounds by Borgs et al., we observe that approximating the value with a precision of ε log n digits (for any constant ε > 0) is NP-hard, where n is the size of the game. On the other hand...

    Full Text Available Despite the fact that the Constitution of South Africa uses language that could be described as “value-language”, our country is experiencing an intense moral crisis. There is an urgent need to establish ways of finding answers to the value crisis in South Africa. Morality has been and is part of education. In this article the relationship between values, education and discipline is addressed from a Biblically-based (in this case, reformational perspective. The teacher as secondary educator plays an important role in the establishment of values among learners. The Department of Education has made clear its intention to establish values in schools in its Manifesto on Values, Education and Democracy. The values emphasised in this document concur with the ideals of nation-building in the new democratic South Africa. Unfortunately, the absence of discipline and self-discipline among learners and educators implies that these ideals cannot be realised. The main cause of discipline problems can possibly be ascribed to the absence of a value system rooted in a specific life and worldview, for without such a perspective the management of discipline problems can only be symptomatic.

    years of age or older with adequate lung function. Results:  We used sex-stratified multiple linear regression analysis to find prediction formulas for forced expiratory volume in 1 s (FEV(1) ), forced vital capacity (FVC) and FEV(1) /FVC adjusted for age and height. The cutoff value of normal lung......Introduction:  International recommendations state that reference values for lung function should derive from cross-sectional studies of healthy nonsmokers and be renewed from time to time because of cohort effect and newer, more accurate, technical equipment. In 1986, the Danish Lung Society...... published reference values for spirometry based on 570 individuals aged 30-70 years. Objectives:  To produce new reference values for lung function and to extend the existing values by including individuals between 20 and 30 years of age and older than 70 years of age.

    In the current health care system, high costs without proportional improvements in quality or outcome have prompted widespread calls for change in how we deliver and pay for care. Value-based health care delivery models have been proposed. Multiple impediments exist to achieving value, including misaligned patient and provider incentives, information asymmetries, convoluted and opaque cost structures, and cultural attitudes toward cancer treatment. Radiation oncology as a specialty has recently become a focus of the value discussion. Escalating costs secondary to rapidly evolving technologies, safety breaches, and variable, nonstandardized structures and processes of delivering care have garnered attention. In response, we present a framework for the value discussion in radiation oncology and identify approaches for attaining value, including economic and structural models, process improvements, outcome measurement, and cost assessment.
