    This paper examines the short run inefficiencies that arise during gradual implementation of a new cost-effective technology in healthcare. These inefficiencies arise when health gains associated with the new technology cannot be obtained immediately because the new technology does not yet supply all patients, and when there is overcapacity for the old technology in the short run because the supply of care is divided among two mutually exclusive technologies. Such efficiency losses are not taken into account in standard textbook cost-effectiveness analysis in which a steady state is presented where costs and effects are assumed to be unchanging over time. A model is constructed to quantify such short run inefficiencies as well as to inform the decision maker about the optimal implementation pattern for the new technology. The model operates by integrating the incremental net benefit equations for both the period of co-existence of mutually exclusive technologies and the period after complete substitution of the old technology. It takes into account the rate of implementation of the new technology, depreciation of capital of the old technology as well as the demand curves for both technologies. The model is applied to the real world case of converting from screen film to digital mammography in the Netherlands.

  3. Electricity prices and fuel costs. Long-run relations and short-run dynamics

    The paper examines the long-run relation and short-run dynamics between electricity prices and three fossil fuel prices - coal, natural gas and crude oil - using annual data for the U.S. for 1960-2007. The results suggest (1) a stable long-run relation between real prices for electricity and coal (2) Bi-directional long-run causality between coal and electricity prices. (3) Insignificant long-run relations between electricity and crude oil and/or natural gas prices. And (4) no evidence of asymmetries in the adjustment of electricity prices to deviations from equilibrium. A number of implications are addressed. (author)

  4. Analyzing the Effects of the Iranian Energy Subsidy Reform Plan on Short- Run Marginal Generation Cost of Electricity Using Extended Input-Output Price Model

    Full Text Available Subsidizing energy in Iran has imposed high costs on country's economy. Thus revising energy prices, on the basis of a subsidy reform plan, is a vital remedy to boost up the economy. While the direct consequence of cutting subsidies on electricity generation costs can be determined in a simple way, identifying indirect effects, which reflect higher costs for input factors such as labor, is a challenging problem. In this paper, variables such as compensation of employees and private consumption are endogenized by using extended Input-Output (I-O price model to evaluate direct and indirect effects of electricity and fuel prices increase on economic subsectors. The determination of the short-run marginal generation cost of electricity using I-O technique with taken into account the Iranian targeted subsidy plan's influences is the main goal of this paper. Marginal cost of electricity, in various scenarios of price adjustment of energy, is estimated for three conventional categories of thermal power plants. Our results show that the raising the price of energy leads to an increase in the electricity production costs. Accordingly, the production costs will be higher than 1000 Rials per kWh until 2014 as predicted in the beginning of the reform plan by electricity suppliers.

    2000-01-01

    This article discusses a number of issues that will become increasingly important now that the concept of marginal external cost pricing becomes more likely to be implemented as a policy strategy in transport in reality. The first part of the article deals with the long-run efficiency of marginal external cost pricing. It is shown that such prices not only optimize short-run mobility, given the shape and position of the relevant demand and cost curves, but even more importantly, also optimall...

  6. Short Run Profit Maximization in a Convex Analysis Framework

    Directory of Open Access Journals (Sweden)

    Ilko Vrankic

    2017-03-01

    Full Text Available In this article we analyse the short run profit maximization problem in a convex analysis framework. The goal is to apply the results of convex analysis due to unique structure of microeconomic phenomena on the known short run profit maximization problem where the results from convex analysis are deductively applied. In the primal optimization model the technology in the short run is represented by the short run production function and the normalized profit function, which expresses profit in the output units, is derived. In this approach the choice variable is the labour quantity. Alternatively, technology is represented by the real variable cost function, where costs are expressed in the labour units, and the normalized profit function is derived, this time expressing profit in the labour units. The choice variable in this approach is the quantity of production. The emphasis in these two perspectives of the primal approach is given to the first order necessary conditions of both models which are the consequence of enveloping the closed convex set describing technology with its tangents. The dual model includes starting from the normalized profit function and recovering the production function, and alternatively the real variable cost function. In the first perspective of the dual approach the choice variable is the real wage, and in the second it is the real product price expressed in the labour units. It is shown that the change of variables into parameters and parameters into variables leads to both optimization models which give the same system of labour demand and product supply functions and their inverses. By deductively applying the results of convex analysis the comparative statics results are derived describing the firm's behaviour in the short run.

  7. Supply security and short-run capacity markets for electricity

    International Nuclear Information System (INIS)

    Creti, Anna; Fabra, Natalia

    2007-01-01

    The creation of electricity markets has raised the fundamental question as to whether markets create the right incentives for the provision of the reserves needed to maintain supply security in the short-run, or whether some form of regulation is required. In some states in the US, electricity distributors have been made responsible for providing such reserves by contracting capacity in excess of their forecasted peak demand. The so-called Installed Capacity Markets provide one means of contracting reserves, and are the subject of this paper. Under monopoly as well as under perfect competition, we identify firms' short-run opportunity costs of committing resources in the capacity market and the costs of inducing full capacity commitment. The long-run investment problem is not considered. From a welfare viewpoint, we also compare the desirability of providing reserves either through capacity markets or through the demand side (i.e. power curtailments). At the optimum, capacity obligations equal peak demand (plus expected outages) and the capacity deficiency rate (which serves as a price cap) is set at firms' opportunity costs of providing full capacity commitment.

    Ring, B. J.; Read, E. G.

    1996-01-01

    In response to the need for more responsive, competitive and decentralized pricing strategies forced upon the industry by deregulation, this study reviewed the type of electricity pricing required to coordinate a competitive wholesale electricity market over time periods typically of the order of one hour. It was found that nodal spot pricing can provide a straight-forward mechanism for providing the correct signals to market participants, while reflecting the costs and complexities of transmission network operation. Provided that all binding constraints are represented in the pricing model, and assuming that they are used in conjunction with long term contracts and capacity rights, such pricing can potentially deliver most of the benefits promised by perfect coordination, while allowing competition to flourish. 4 refs

    2010-01-01

    The author argues that the aggregate demand/aggregate supply (AD/AS) model is significantly improved--although certainly not perfected--by trimming it of the short-run aggregate supply (SRAS) curve. Problems with the SRAS curve are shown first for the AD/AS model that casts the AD curve as identifying the equilibrium level of output associated…

    Macide ÇİÇEK

    2005-01-01

    Full Text Available In this study, it is employed that Expectations-Augmented Philips Curve Model to investigate the link between inflation and unit labor costs, output gap (proxy for demand shocks, real exchange rate (proxy for supply shocks and price expectations for Turkey using monthly data from 2000:01 to 2004:12. The methodology employed in this paper uses unit root test, Johansen Cointegration Test to examine the existence of possible long run relationships among the variables included in the model and a single equation error correction model for the inflation equation estimated by OLS to examine the short run dynamics of inflation, respectively. It is find that in the long run, mark-up behaviour of output prices over unit labor costs is the main cause of inflation, real exchange rate has a rather big impact on reduced inflation and demand shocks don’t led to an increase in prices. The short run dynamics of the inflation equation indicate that supply shocks are the determinant of inflation in the short run. It is also find that exchange rate is the variable that trigger an inflation adjustment the most rapidly in the short run.

    Full Text Available Using the short-run statistic indicators is a compulsory requirement implied in the current analysis. Therefore, there is a system of EUROSTAT indicators on short run which has been set up in this respect, being recommended for utilization by the member-countries. On the basis of these indicators, there are regular, usually monthly, analysis being achieved in respect of: the production dynamic determination; the evaluation of the short-run investment volume; the development of the turnover; the wage evolution: the employment; the price indexes and the consumer price index (inflation; the volume of exports and imports and the extent to which the imports are covered by the exports and the sold of trade balance. The EUROSTAT system of indicators of conjuncture is conceived as an open system, so that it can be, at any moment extended or restricted, allowing indicators to be amended or even removed, depending on the domestic users requirements as well as on the specific requirements of the harmonization and integration. For the short-run analysis, there is also the World Bank system of indicators of conjuncture, which is utilized, relying on the data sources offered by the World Bank, The World Institute for Resources or other international organizations statistics. The system comprises indicators of the social and economic development and focuses on the indicators for the following three fields: human resources, environment and economic performances. At the end of the paper, there is a case study on the situation of Romania, for which we used all these indicators.

  9. Risks, Information and Short-Run Timber Supply

    Directory of Open Access Journals (Sweden)

    Francesca Rinaldi

    2013-12-01

    Full Text Available Efforts to increase wood mobilization have highlighted the need to appraise drivers of short-run timber supply. The current study aims to shed further light on harvesting decisions of private forest owners, by investigating optimal harvesting under uncertainty, when timber revenues are invested on financial markets and uncertainty is mitigated by news releases. By distinguishing between aggregate economic risk and sector specific risks, the model studies in great detail optimal harvesting-investment decisions, with particular emphasis on the non-trivial transmission of risk on optimal harvesting, and on the way private forest owners react to news and information. The analysis of the role played by information in harvesting decisions is a novelty in forest economic theory. The presented model is highly relevant from a policy—information is a commonly used forest policy instrument—as well as a practical perspective, since the mechanism of risk transmission is at the basis of timber pricing.

    Recent research shows significant differences in the levelised photovoltaics (PV) electricity cost calculations. The present paper points out that no unique or absolute cost figure can be justified, the correct solution is to use a range of cost figures that is determined in a dynamic power portfolio interaction within the financial scheme, support mechanism and industry cost reduction. The paper draws attention to the increasing role of financial investors in the PV segment of the renewable energy market and the importance they attribute to the risks of all options in the power generation portfolio. Based on these trends, a former version of a financing model is adapted to project the energy mix changes in the EU electricity market due to investors behaviour with different risk tolerance/aversion. The dynamic process of translating these risks into the return expectation in the financial appraisal and investment decision making is also introduced. By doing so, the paper sets up a potential electricity market trend with the associated risk perception and classification. The necessary risk mitigation tasks for all stakeholders in the PV market are summarised which aims to avoid the burden of excessive risk premiums in this market segment. (author)

    We examine the short-run implications of CO2 trading for power production, prices, emissions, and generator profits in northwest Europe in 2005. Simulation results from a transmission-constrained oligopoly model are compared with theoretical analyses to quantify price increases and windfall profits earned by generators. The analyses indicate that the rates at which CO2 costs are passed through to wholesale prices are affected by market competitiveness, merit order changes, and elasticities of demand and supply. Emissions trading results in large windfall profits, much but not all of which is due to free allocation of allowances. Profits also increase for some generators because their generation mix has low emissions, and so they benefit from electricity price increases. Most emission reductions appear to be due to demand response, not generation redispatch

    2015-01-01

    Pakistan is in a deep power crisis since 2008 which the government is trying to control by adding new generation capacity. This strategy, however, will not be helpful in the short-run. The only way, the power crisis can be controlled or mitigated in the short-run, is to efficiently utilize the available resources. Government lacks such a strategy at this point. The paper provides such a strategy by setting up a power sector model with multiple modules of generation, transmission and distribution. The model provides an efficient way of utilizing the available resources and can be used to perform simulations at different stages of the supply-chain. The results of model show that, if the given resources are utilized efficiently, the power generation increases by 3222 GWh or 5 percent of the current output and the revenue increases by $945 million or 12 percent. The extra generated power decrease the cost of power production by 0.52 ¢/KWh cents and reduces the power load-shedding for 2–3 h. These outcomes can significantly relieve the sector and the people of Pakistan. The results of the model have important policy implications on working of the sector and circular debt reduction. - Highlights: • Government needs a new strategy to come out of the power crisis along with adding new power generation. • Because one major reason of current power crisis is the inefficient use of available resources. • Focus of this paper is to provide such a strategy by setting up a power sector supply-chain model. • When resources are utilized efficiently, power generation and revenue increases by 5 and 12 percent respectively. • These outputs decreases cost of power production by 0.52¢/KWh and power load-shedding by 2–3 h.

    Full Text Available Investors constantly look for significant predictors and accurate models to forecast future results, whose occasional efficacy end up being neutralized by market efficiency. Regardless, such predictors are widely used for seeking better (and more unique perceptions. This paper aims to investigate to what extent some of the most notorious indicators have discriminatory power to select stocks, and if it is feasible with such variables to build models that could anticipate those with good performance. In order to do that, logistical regressions were conducted with stocks traded at Bovespa using the selected indicators as explanatory variables. Investigated in this study were the outputs of Bovespa Index, liquidity, the Sharpe Ratio, ROE, MB, size and age evidenced to be significant predictors. Also examined were half-year, logistical models, which were adjusted in order to check the potential acceptable discriminatory power for the asset selection.

  11. Examining the short-run price elasticity of gasoline demand in the United States

    Brannan, Michael James

    Estimating the consumer demand response to changes in the price of gasoline has important implications regarding fuel tax policies and environmental concerns. There are reasons to believe that the short-run price elasticity of gasoline demand fluctuates due to changing structural and behavioral factors. In this paper I estimate the short-run price elasticity of gasoline demand in two time periods, from 2001 to 2006 and from 2007 to 2010. This study utilizes data at both the national and state levels to produce estimates. The short-run price elasticities range from -0.034 to -0.047 during 2001 to 2006, compared to -0.058 to -0.077 in the 2007 to 2010 period. This paper also examines whether there are regional differences in the short-run price elasticity of gasoline demand in the United States. However, there appears to only be modest variation in price elasticity values across regions.

    Full Text Available This study examines the long term relationship of risk premium and fundamental factors in emerging stock markets of China, India and Pakistan keeping in view leading contribution of Fama and French (1992 and Carhart (1997 models. Contrary to the macroeconomic multifactor models, this study incorporates firm-specific risk factors related to the market premium; size (SMB, value (HML, momentum (WML and growth (UMD as determinants of risk premium. The firm-specific growth factor is incorporated based on evidence from Ho, Strange, and Piesse (2008 by employing (UMD which is based on assets to market equity of the firm. Sample of 1198 companies from the three emerging markets for the period of 2001-2013 depicts market risk premium as the leading factor affecting risk premium in Indian and the Pakistani markets. Results reveal market momentum being high enough to overestimate coefficients in the short run. However, the relationship is stabilized and adjusted in the long run. Chinese markets, where all the risk factors seem to play their role to determine risk premium, are relatively much stable and grown-up and clearly represent maturity of the Chinese markets. Distinction between the short run and long run might be useful for the investors of the three emerging economies. According to the principle of high risk associated with high returns, small value happens to deliver higher returns with higher volatility. The growth stocks outperform value stocks in these economies.

  15. Short-run Economic Assessment of the Transportation Recovery Policy After an Earthquake

    Directory of Open Access Journals (Sweden)

    Koike Atsushi

    2017-01-01

    Full Text Available This paper develops a short-run economic damage assessment model. The model contains two sub models. One is the conventional traffic assignment model, which calculates traveling time under the damaged transportation infrastructure. The other is the economic damage assessment model, which determines the decrease in production level in the short run. This method facilitates the identification of critical infrastructure that could reduce the economic damage when the disaster occurs. As a case study, we applied this model to several recovery plans for transport facilities. The results suggest that the proposed comprehensive model should be considered as a prevention plan.

    McKean, John R.; Johnson, Donn; Taylor, R. Garth

    2010-09-01

    Choice of the appropriate model of economic behavior is important for the measurement of nonmarket demand and benefits. Several travel cost demand model specifications are currently in use. Uncertainty exists over the efficacy of these approaches, and more theoretical and empirical study is warranted. Thus travel cost models with differing assumptions about labor markets and consumer behavior were applied to estimate the demand for steelhead trout sportfishing on an unimpounded reach of the Snake River near Lewiston, Idaho. We introduce a modified two-step decision model that incorporates endogenous time value using a latent index variable approach. The focus is on the importance of distinguishing between short-run and long-run consumer decision variables in a consistent manner. A modified Barnett two-step decision model was found superior to other models tested.

    Directory of Open Access Journals (Sweden)

    Seung-Hoon Yoo

    2012-11-01

    Full Text Available This paper investigates the demand function for diesel in Korea covering the period 1986–2011. The short-run and long-run elasticities of diesel demand with respect to price and income are empirically examined using a co-integration and error-correction model. The short-run and long-run price elasticities are estimated to be −0.357 and −0.547, respectively. The short-run and long-run income elasticities are computed to be 1.589 and 1.478, respectively. Thus, diesel demand is relatively inelastic to price change and elastic to income change in both the short-run and long-run. Therefore, a demand-side management through raising the price of diesel will be ineffective and tightening the regulation of using diesel more efficiently appears to be more effective in Korea. The demand for diesel is expected to continuously increase as the economy grows.

    2012-01-01

    The fixed effects (FE) estimator of "conditional convergence" in income based dynamic panel models could be biased downward when capital adjustment cost is present. Such a capital adjustment cost means a rising marginal cost of investment which could slow down the convergence. The standard FE regression fails to take into account of this capital adjustment cost and thus it could overestimate the rate of convergence. Using a Ramsey model with long-run adjustment cost of capital, we characteriz...

In this paper, we analyze whether the presence of quantity-adjustments costs, which presumably are significant, change the traditional results on the impact of inflation....... In particular, recent findings suggest that quantity-adjustment costs may remove the linkage between output and inflation. We show that this is not the case when inflation is anticipated. On the contrary, quantity-adjustment costs may significantly amplify the consequences of price-adjustment costs...

  7. Forecasting short-run crude oil price using high- and low-inventory variables

    International Nuclear Information System (INIS)

    Ye, Michael; Zyren, John; Shore, Joanne

    2006-01-01

    Since inventories have a lower bound or a minimum operating level, economic literature suggests a nonlinear relationship between inventory level and commodity prices. This was found to be the case in the short-run crude oil market. In order to explore this inventory-price relationship, two nonlinear inventory variables are defined and derived from the monthly normal level and relative level of OECD crude oil inventories from post 1991 Gulf War to October 2003: one for the low inventory state and another for the high inventory state of the crude oil market. Incorporation of low- and high-inventory variables in a single equation model to forecast short-run WTI crude oil prices enhances the model fit and forecast ability

  8. Short-run and long-run elasticities of import demand for crude oil in Turkey

    International Nuclear Information System (INIS)

    Altinay, Galip

    2007-01-01

    The aim of this study is to attempt to estimate the short-run and the long-run elasticities of demand for crude oil in Turkey by the recent autoregressive distributed lag (ARDL) bounds testing approach to cointegration. As a developing country, Turkey meets its growing demand for oil principally by foreign suppliers. Thus, the study focuses on modelling the demand for imported crude oil using annual data covering the period 1980-2005. The bounds test results reveal that a long-run cointegration relationship exists between the crude oil import and the explanatory variables: nominal price and income, but not in the model that includes real price in domestic currency. The long-run parameters are estimated through a long-run static solution of the estimated ARDL model, and then the short-run dynamics are estimated by the error correction model. The estimated models pass the diagnostic tests successfully. The findings reveal that the income and price elasticities of import demand for crude oil are inelastic both in the short run and in the long run

  9. The hidden cost of investment. The impact of adjustment costs on firm performance measurement and regulation

    International Nuclear Information System (INIS)

    Nick, Sebastian; Wetzel, Heike

    2014-01-01

    In this study, we address a major problem in the measurement of firm performance and the regulation of natural monopolies, namely the intertemporal character of long-term investment decisions. In specific, we focus on the impact of adjustment costs of investments on estimates of firms' technical and cost inefficiency. We apply nonparametric dynamic data envelopment analysis to investigate the dynamic inefficiency of electricity distribution and transmission companies in the US during the years 2004 to 2011 and compare our results with their static counterparts. Our empirical findings reveal that ignoring long-term investments and their corresponding adjustment costs does significantly distort both firm-specific and industrial inefficiency estimates and may thus create misleading incentives for the regulated firms to cut investments.

    Finkelstein, Eric A; Allaire, Benjamin T; Dibonaventura, Marco Dacosta; Burgess, Somali M

    2012-01-01

    The objective of this study was to estimate the time to breakeven and 5-year net costs of laparoscopic adjustable gastric banding (LAGB) taking both direct and indirect costs and cost savings into account. Estimates of direct cost savings from LAGB were available from the literature. Although longitudinal data on indirect cost savings were not available, these estimates were generated by quantifying the relationship between medical expenditures and absenteeism and between medical expenditures and presenteeism (reduced on-the-job productivity) and combining these elasticity estimates with estimates of the direct cost savings to generate total savings. These savings were then combined with the direct and indirect costs of the procedure to quantify net savings. By including indirect costs, the time to breakeven was reduced by half a year, from 16 to 14 quarters. After 5 years, net savings in medical expenditures from a gastric banding procedure were estimated to be $4970 (±$3090). Including absenteeism increased savings to $6180 (±$3550). Savings were further increased to $10,960 (±$5864) when both absenteeism and presenteeism estimates were included. This study presented a novel approach for including absenteeism and presenteeism estimates in cost-benefit analyses. Application of the approach to gastric banding among surgery-eligible obese employees revealed that the inclusion of indirect costs and cost savings improves the business case for the procedure. This approach can easily be extended to other populations and treatments. Copyright © 2012 International Society for Pharmacoeconomics and Outcomes Research (ISPOR). Published by Elsevier Inc.

  20. Short-Run Contexts and Imperfect Testing for Continuous Sampling Plans

    Directory of Open Access Journals (Sweden)

    Mirella Rodriguez

    2018-04-01

    Full Text Available Continuous sampling plans are used to ensure a high level of quality for items produced in long-run contexts. The basic idea of these plans is to alternate between 100% inspection and a reduced rate of inspection frequency. Any inspected item that is found to be defective is replaced with a non-defective item. Because not all items are inspected, some defective items will escape to the customer. Analytical formulas have been developed that measure both the customer perceived quality and also the level of inspection effort. The analysis of continuous sampling plans does not apply to short-run contexts, where only a finite-size batch of items is to be produced. In this paper, a simulation algorithm is designed and implemented to analyze the customer perceived quality and the level of inspection effort for short-run contexts. A parameter representing the effectiveness of the test used during inspection is introduced to the analysis, and an analytical approximation is discussed. An application of the simulation algorithm that helped answer questions for the U.S. Navy is discussed.

  1. Emission intensity in New Zealand manufacturing and the short-run impacts of emissions pricing

    International Nuclear Information System (INIS)

    Bartleet, Matthew; Iyer, Kris; Numan-Parsons, Elisabeth

    2010-01-01

    This paper reports the greenhouse gas (GHG) emission intensity of the New Zealand (NZ) manufacturing sector at a combination of industry group and class levels (sub-sectors). The short-run impacts of a price on emissions are investigated with a focus on exporting activities. Sub-sectors that could be materially impacted by an expected range of emissions prices accounted for slightly over 9% of national gross domestic product. It is found that there is much variability of emission intensity within manufacturing and even within sub-sectors. An assessment of trade intensities further indicates that several emissions-intensive activities are also export-intensive. These activities are at most risk of losing competitiveness in the short-run if they are subjected to a price on GHG emissions that their competitors in other countries are not.

    Full Text Available This study examined the economic relationship among agriculture and petroleum sectors and growth of Nigeria’s economy as well as the effects of these two key sectors on the economic growth. The Bound (ARDL test which was used to examine the long-run relationship among the variables revealed that there is a long-run relationship among agricultural and petroleum sectors and economic growth. In the short run, both sectors have positive significant relationship with the economic growth. While for every 1% change in agricultural productivity there is about 60.89% change on economic growth, petroleum sector had about 37.07% change effect. Thus, agriculture contributes more than the petroleum sector in the short run. In the long-run, both sectors also have positive relationship with economic growth. Agriculture in the long-run also contribute more than the petroleum sector. While a 1% change in agricultural productivity effects a 53.49% increase in economic growth, petroleum sector increases GDP by 43.71%. However, in the long-run, while agriculture is significant at 5%, petroleum sector is significant at 10%. In conclusion, the positive relationship of both sectors with economic growth shows that they are rather economically complimentary than competitive that the actions and inactions of the government have made them look.

    Owing to the diverse nuclear fuel cycle options available, including direct disposal, it is necessary to select the optimum nuclear fuel cycles in consideration of the political and social environments as well as the technical stability and economic efficiency of each country. Economic efficiency is therefore one of the significant evaluation standards. In particular, because nuclear fuel cycle cost may vary in each country, and the estimated cost usually prevails over the real cost, when evaluating the economic efficiency, any existing uncertainty needs to be removed when possible to produce reliable cost information. Many countries still do not have reprocessing facilities, and no globally commercialized HLW (High-level waste) repository is available. A nuclear fuel cycle cost estimation model is therefore inevitably subject to uncertainty. This paper analyzes the uncertainty arising out of a nuclear fuel cycle cost evaluation from the viewpoint of a cost estimation model. Compared to the same discount rate model, the nuclear fuel cycle cost of a different discount rate model is reduced because the generation quantity as denominator in Equation has been discounted. Namely, if the discount rate reduces in the back-end process of the nuclear fuel cycle, the nuclear fuel cycle cost is also reduced. Further, it was found that the cost of the same discount rate model is overestimated compared with the different discount rate model as a whole.

  7. Modified SPC for short run test and measurement process in multi-stations

    Science.gov (United States)

    Koh, C. K.; Chin, J. F.; Kamaruddin, S.

    2018-03-01

    Due to short production runs and measurement error inherent in electronic test and measurement (T&M) processes, continuous quality monitoring through real-time statistical process control (SPC) is challenging. Industry practice allows the installation of guard band using measurement uncertainty to reduce the width of acceptance limit, as an indirect way to compensate the measurement errors. This paper presents a new SPC model combining modified guard band and control charts (\\bar{\\text{Z}} chart and W chart) for short runs in T&M process in multi-stations. The proposed model standardizes the observed value with measurement target (T) and rationed measurement uncertainty (U). S-factor (S f) is introduced to the control limits to improve the sensitivity in detecting small shifts. The model was embedded in automated quality control system and verified with a case study in real industry.

    Full Text Available This paper aims at empirically examining the short-run and long-run causal relationship between the Indonesian Islamic stock returns and selected macroeconomic variables namely inflation, money supply and exchange rate during the pre- and post- 2008 global financial turmoil period from 2002 until 2007 and from 2008 until 2013 by using monthly data. The methodology used in this study is time series econometric techniques i.e. the unit root test,co-integration test, error correction model (ECM and variance decompositions(VDCs. The findings showed that there is cointegration between Islamic stock prices and macroeconomic variables. The results suggest that inflation, money supply, and exchange rate significantly affected the Islamic stock returns in Indonesia. These variables should be taken into account by the policy-makers as the important policy instruments in stabilizing Islamic stock markets in the countryDOI: 10.15408/aiq.v8i1.2505

  14. Cost per quality-adjusted life year and disability-adjusted life years: the need for a new paradigm.

    Science.gov (United States)

    Bevan, Gwyn; Hollinghurst, Sandra

    2003-08-01

    Two different paradigms have been proposed for setting priorities for access to healthcare: cost per quality-adjusted life year based on interventions, and disability-adjusted life years based on the burden of disease in a population. These formal paradigms make explicit the assumptions made implicitly every day in delivering and hence rationing access to healthcare. This paper outlines each paradigm's methodological problems and argues that each paradigm is incomplete in terms of providing the information necessary for making budgetary decisions on healthcare. It argues that a scientific revolution is required to create a new paradigm by combining the strengths of each.

  2. Utility-adjusted analysis of the cost of palliative radiotherapy for bone metastases

    International Nuclear Information System (INIS)

    Barton, M.B.; Jacob, S.A.

    2003-01-01

    Palliative radiotherapy is effective in the treatment of bone metastases but is under-utilized, possibly because it is perceived to be expensive. We performed a cost-utility analysis of palliative radiotherapy for bone metastases, evaluating both the actual cost of radiotherapy as well as its impact on quality of life by adjusting for the variation in response to treatment. Hospital records between July 1991 and July 1996 were reviewed to ascertain the number of patients treated with palliative radiotherapy for bone metastases, the average number of fields of radiation delivered to each patient and the average duration of survival. Partial and complete response rates to palliative radiotherapy were obtained from a review of all published randomized controlled trials of radiation treatment of bone metastases. Utility values were assigned to the response rates, and an overall adjusted response rate to radiotherapy was derived. The cost of delivering a field of radiation was calculated. The total cost was divided by the total number of response months to give a utility-adjusted cost per month of palliative radiotherapy. The utility-adjusted cost per month of palliative radiotherapy of bone metastases was found to be AUS$ 100 per month or AUS$ 1200 per utility-adjusted life-year. This study demonstrates that, contrary to popular perception, palliative radiotherapy is a cost-effective treatment modality for bone metastases. Copyright (2003) Blackwell Science Pty Ltd

    Full Text Available The objective of this paper is to learn about the effects of the adjustment costs, economic growth, imports and exports on human capital labor demand. The dynamic model proposed by Sargent (1978 was adjusted to consider three types of human capital: (a one with fundamental education (1–8 years of schooling; (b one with secondary education level (9–11 years of education; (c and one with tertiary education level (12 years or more of schooling. Using state level panel data, the dynamic econometrics estimates showed the following results: (i the labor market adjustment costs are very higher; (ii the adjustment cost for the human capital with intermediary education level is the highest one compared to the others; (iii the states’ economic growth favor those with superior education; (iv the imports seems to favor the demand for those with intermediate education levels; (v the degree of openness does show some weak effect on the demand for human capitals with intermediate education. In sum, the growing demand for human capital with some superior education seems to be more associated to its lower adjustment cost and economic growth; the non-significance of real wage elasticity and high adjustment cost seems to indicate that the human capital with intermediate knowledge is in short supply; hence, economic education policy that increases supply of such human capital are in need.

  5. THE LONG-RUN AND SHORT-RUN EFFECTS OF CRUDE OIL PRICE ON METHANOL MARKET IN IRAN

    Directory of Open Access Journals (Sweden)

    Akbar Komijani

    2013-01-01

    Full Text Available Substituting crude oil exports with value-added petrochemical products is one of the main strategies for policy makers in oil-driven economies to isolating the real sectors of economy from oil price volatility. This policy inclination has led to a body of literature in energy economics in recent decades. As a case study, this paper investigates the short-run and long-run relationship between Iran’s oil price and methanol price which is one of the most important non-oil exports of the oil-exporting country. To do so, the weekly data from 18 Jan. 2009 to 18 Sep. 2011 in a VECM framework is applied. The results show that in the long-run, oil price hikes leads to proportional increase in methanol price while in the short-run, this impact is not significant.

  9. Cost-Effective Adjustments to Nursing Home Staffing to Improve Quality.

    Science.gov (United States)

    Bowblis, John R; Roberts, Amy Restorick

    2018-06-01

    Health care providers face fixed reimbursement rates from government sources and need to carefully adjust staffing to achieve the highest quality within a given cost structure. With data from the Certification and Survey Provider Enhanced Reports (1999-2015), this study holistically examined how staffing levels affect two publicly reported measures of quality in the nursing home industry, the number of deficiency citations and the deficiency score. While higher staffing consistently yielded better quality, the largest quality improvements resulted from increasing administrative registered nurses and social service staffing. After adjusting for wages, the most cost-effective investment for improving overall deficiency outcomes was increasing social services. Deficiencies related to quality of care were improved most by increasing administrative nursing and social service staff. Quality of life deficiencies were improved most by increasing social service and activities staff. Approaches to improve quality through staffing adjustments should target specific types of staff to maximize return on investment.

  10. Evidence that Risk Adjustment is Unnecessary in Estimates of the User Cost of Money

    Directory of Open Access Journals (Sweden)

    Diego A. Restrepo-Tobón

    2015-12-01

    Full Text Available Investors value the  special attributes of monetary assets (e.g.,  exchangeability, liquidity, and safety  and pay a premium for holding them in the form of a lower return rate. The user cost of holding monetary assets can be measured approximately by the difference between the  returns on illiquid risky assets and  those of safer liquid assets. A more appropriate measure should adjust this difference by the  differential risk of the  assets in question. We investigate the  impact that time  non-separable preferences has on the  estimation of the  risk-adjusted user cost of money. Using U.K. data from 1965Q1 to 2011Q1, we estimate a habit-based asset pricing model  with money  in the utility function and  find that the  risk  adjustment for risky monetary assets is negligible. Thus, researchers can dispense with risk adjusting the  user cost of money  in constructing monetary aggregate indexes.

  11. Oligopoly games with nonlinear demand and cost functions: Two boundedly rational adjustment processes

    International Nuclear Information System (INIS)

    Naimzada, Ahmad K.; Sbragia, Lucia

    2006-01-01

    We consider a Cournot oligopoly game, where firms produce an homogenous good and the demand and cost functions are nonlinear. These features make the classical best reply solution difficult to be obtained, even if players have full information about their environment. We propose two different kinds of repeated games based on a lower degree of rationality of the firms, on a reduced information set and reduced computational capabilities. The first adjustment mechanism is called 'Local Monopolistic Approximation' (LMA). First firms get the correct local estimate of the demand function and then they use such estimate in a linear approximation of the demand function where the effects of the competitors' outputs are ignored. On the basis of this subjective demand function they solve their profit maximization problem. By using the second adjustment process, that belongs to a class of adaptive mechanisms known in the literature as 'Gradient Dynamics' (GD), firms do not solve any optimization problem, but they adjust their production in the direction indicated by their (correct) estimate of the marginal profit. Both these repeated games may converge to a Cournot-Nash equilibrium, i.e. to the equilibrium of the best reply dynamics. We compare the properties of the two different dynamical systems that describe the time evolution of the oligopoly games under the two adjustment mechanisms, and we analyze the conditions that lead to non-convergence and complex dynamic behaviors. The paper extends the results of other authors that consider similar adjustment processes assuming linear cost functions or linear demand functions

    Households will purchase more items than usual prior to a value added tax (VAT) rate increase in order to avoid taxation. Since this type of arbitrage requires resources such as shopping time and storage space, the impacts of tax increases vary across households, which has brought distributional effects in the short-run. Using the case of a consumption tax rate increase in Japan in 1997, we show that households who are non-working, with non-working spouses and residing in larger houses, benef...

  13. Some adjustments to the human capital and the friction cost methods.

    Science.gov (United States)

    Targoutzidis, Antonis

    2018-03-21

    The cost of lost output is a major component of the total cost of illness estimates, especially those for the cost of workplace accidents and diseases. The two main methods for estimating this output, namely the human capital and the friction cost method, lead to very different results, particularly for cases of long-term absence, which makes the choice of method a critical dilemma. Two hidden assumptions, one for each method, are identified in this paper: for human capital method, the assumption that had the accident not happened the individual would remain alive, healthy and employed until retirement, and for friction cost method, the assumption that any created vacancy is covered by an unemployed person. Relevant adjustments to compensate for their impact are proposed: (a) to depreciate the estimates of the human capital method for the risks of premature death, disability or unemployment and (b) to multiply the estimates of the friction cost method with the expected number of job shifts that will be caused by a disability. The impact of these adjustments on the final estimates is very important in terms of magnitude and can lead to better results for each method.

  15. Cost per QALY (quality-adjusted life year and lifetime cost of prolonged mechanical ventilation in Taiwan.

    Directory of Open Access Journals (Sweden)

    Mei-Chuan Hung

    Full Text Available INTRODUCTION: Patients who require prolonged mechanical ventilation (PMV are increasing and producing financial burdens worldwide. This study determines the cost per QALY (quality-adjusted life year, out-of-pocket expenses, and lifetime costs for PMV patients stratified by underlying diseases and cognition levels. METHODS: A nationwide sample of 50,481 patients with continual mechanical ventilation for more than 21 days was collected during 1997-2007. After stratifying the patients according to specific diagnoses, a latent class analysis (LCA was performed to categorise PMV patients with multiple co-morbidities into several homogeneous groups. The survival functions were estimated for individual groups using the Kaplan-Meier method and extrapolated to 300 months through a semi-parametric method. The survival functions were adjusted using an EQ-5D utility value derived from a convenience sample of 142 PMV patients to estimate quality-adjusted life expectancies (QALE. Another convenience sample of 165 patients was used to estimate the out-of-pocket expenses. The lifetime expenditures paid by the single-payer National Health Insurance (NHI system and patients' families were estimated by multiplying average monthly expenditures by the survival probabilities and summing the values over lifetime. RESULTS: PMV therapy costs more than 100,000 U.S. dollars (USD per QALY for all patients with poor cognition. For patients with partial cognition, PMV therapy costs less than 56,000 USD per QALY for those with liver cirrhosis, intracranial or spinal cord injuries, and 57,000-69,000 USD for patients with multiple co-morbidities under age of 65. The average lifetime cost of PMV was usually below 56,000 USD. The out-of-pocket expenses were often more than one-third of the total cost of treatment. CONCLUSIONS: PMV treatment for patients with poor cognition would cost more than 5 times Taiwan's GDP (gross domestic products, or less cost-effective. The out

    Abstract Background: The aim of this study is to determine the most cost-effective strategy for the treatment of primary open-angle glaucoma (POAG) in Brazil, from the payer's perspective (Brazilian Public Health System) in the setting of the Glaucoma Referral Centers. Methods: Study design was a cost-effectiveness analysis of different treatment strategies for POAG. We developed 3 Markov models (one for each glaucoma stage: early, moderate and advanced), using a hypothetical cohort of POAG patients, from the perspective of the Brazilian Public Health System (SUS) and a horizon of the average life expectancy of the Brazilian population. Different strategies were tested according to disease severity. For early glaucoma, we compared observation, laser and medications. For moderate glaucoma, medications, laser and surgery. For advanced glaucoma, medications and surgery. Main outcome measures were ICER (incremental cost-effectiveness ratio), medical direct costs and QALY (quality-adjusted life year). Results: In early glaucoma, both laser and medical treatment were cost-effective (ICERs of initial laser and initial medical treatment over observation only, were R$ 2,811.39/QALY and R$ 3,450.47/QALY). Compared to observation strategy, the two alternatives have provided significant gains in quality of life. In moderate glaucoma population, medical treatment presented the highest costs among treatment strategies. Both laser and surgery were highly cost-effective in this group. For advanced glaucoma, both tested strategies were cost-effective. Starting age had a great impact on results in all studied groups. Initiating glaucoma therapy using laser or surgery were more cost-effective, the younger the patient. Conclusion: All tested treatment strategies for glaucoma provided real gains in quality of life and were cost-effective. However, according to the disease severity, not all strategies provided the same cost-effectiveness profile. Based on our findings, there should be a

    This research analyses the long run and short run relationships among economic growth, poverty and energy using the Colombian case. In this study, we use the time-series methodologies. The results regarding the relationship among economic growth, poverty and energy show that increases in gross domestic product and energy supply per capita should lead a decrease of poverty, which should demonstrate that access to modern and adequate energy services help to decrease poverty and to increase economic growth. Moreover, the improvements in energy efficiency have contributed to increase economic growth from an approach of sustainable development. These results are important for the adequate design, formulation and application of policies and strategies that encourage a better energy use to improve economic growth and decrease poverty, especially in developing countries.

    Males may increase their fitness through extra-pair copulations (copulations outside the pair bond) that result in extra-pair fertilizations, but also risk lost paternity when they leave their own mate unguarded. The fitness costs of cuckoldry for Seychelles warblers (Acrocephalus sechellensis) are considerable because warblers have a single-egg clutch and, given the short breeding season, no time for a successful replacement clutch. Neighbouring males are the primary threat to a male's genetic paternity. Males minimize their loss of paternity by guarding their mates to prevent them from having extra-pair copulations during their fertile period. Here, I provide experimental evidence that mate-guarding behaviour is energetically costly and that the expression of this trade-off is adjusted to paternity risk (local male density). Free-living males that were induced to reduce mate guarding spent significantly more time foraging and gained significantly better body condition than control males. The larger the reduction in mate guarding, the more pronounced was the increase in foraging and body condition (accounting for food availability). An experimental increase in paternity risk resulted in an increase in mate-guarding intensity and a decrease in foraging and body condition, and vice versa. This is examined using both cross-sectional and longitudinal data. This study on the Seychelles warbler offers experimental evidence that mate guarding is energetically costly and adjusted to paternity risk.

    Efforts to regionalize surgery based on thresholds in procedure volume may have consequences on the cost of health care delivery. This study aims to delineate the relationship between hospital volume, case mix, and variability in the cost of operative intervention using colectomy as the model. All patients undergoing colectomy (n = 90,583) at 183 academic hospitals from 2009-2012 in The University HealthSystems Consortium Database were studied. Patient and procedure details were used to generate a case mix-adjusted predictive model of total direct costs. Observed to expected costs for each center were evaluated between centers based on overall procedure volume. Patient and procedure characteristics were significantly different between volume tertiles. Observed costs at high-volume centers were less than at middle- and low-volume centers. According to our predictive model, high-volume centers cared for a less expensive case mix than middle- and low-volume centers ($12,786 vs $13,236 and $14,497, P case mix at low-volume centers, which may lead to perceived poor performance at these centers.

    Asynchrony between patient and ventilator breaths is associated with increased duration of mechanical ventilation (MV). Neurally Adjusted Ventilatory Assist (NAVA) controls MV through an esophageal reading of diaphragm electrical activity via a nasogastric tube mounted with electrode rings. NAVA has been shown to decrease asynchrony in comparison to pressure support ventilation (PSV). The objective of this study was to conduct a health economic evaluation of NAVA compared with PSV. We developed a model based on an indirect link between improved synchrony with NAVA versus PSV and fewer days spent on MV in synchronous patients. Unit costs for MV were obtained from the Swedish intensive care unit register, and used in the model along with NAVA-specific costs. The importance of each parameter (proportion of asynchronous patients, costs, and average MV duration) for the overall results was evaluated through sensitivity analyses. Base case results showed that 21% of patients ventilated with NAVA were asynchronous versus 52% of patients receiving PSV. This equals an absolute difference of 31% and an average of 1.7 days less on MV and a total cost saving of US$7886 (including NAVA catheter costs). A breakeven analysis suggested that NAVA was cost effective compared with PSV given an absolute difference in the proportion of asynchronous patients greater than 2.5% (49.5% versus 52% asynchronous patients with NAVA and PSV, respectively). The base case results were stable to changes in parameters, such as difference in asynchrony, duration of ventilation and daily intensive care unit costs. This study showed economically favorable results for NAVA versus PSV. Our results show that only a minor decrease in the proportion of asynchronous patients with NAVA is needed for investments to pay off and generate savings. Future studies need to confirm this result by directly relating improved synchrony to the number of days on MV. © The Author(s), 2015.

    We show that the effects of taxes on labor supply are shaped by interactions between adjustment costs for workers and hours constraints set by firms. We develop a model in which firms post job offers characterized by an hours requirement and workers pay search costs to find jobs. We present evidence supporting three predictions of this model by analyzing bunching at kinks using Danish tax records. First, larger kinks generate larger taxable income elasticities. Second, kinks that apply to a larger group of workers generate larger elasticities. Third, the distribution of job offers is tailored to match workers' aggregate tax preferences in equilibrium. Our results suggest that macro elasticities may be substantially larger than the estimates obtained using standard microeconometric methods. PMID:21836746

    The ability of individual animals to create functional structures by joining together is rare and confined to the social insects. Army ants (Eciton) form collective assemblages out of their own bodies to perform a variety of functions that benefit the entire colony. Here we examine ‟bridges" of linked individuals that are constructed to span gaps in the colony's foraging trail. How these living structures adjust themselves to varied and changing conditions remains poorly understood. Our field experiments show that the ants continuously modify their bridges, such that these structures lengthen, widen, and change position in response to traffic levels and environmental geometry. Ants initiate bridges where their path deviates from their incoming direction and move the bridges over time to create shortcuts over large gaps. The final position of the structure depended on the intensity of the traffic and the extent of path deviation and was influenced by a cost-benefit trade-off at the colony level, where the benefit of increased foraging trail efficiency was balanced by the cost of removing workers from the foraging pool to form the structure. To examine this trade-off, we quantified the geometric relationship between costs and benefits revealed by our experiments. We then constructed a model to determine the bridge location that maximized foraging rate, which qualitatively matched the observed movement of bridges. Our results highlight how animal self-assemblages can be dynamically modified in response to a group-level cost-benefit trade-off, without any individual unit's having information on global benefits or costs.

    Technology drives both health care spending and health improvement. Yet policy makers rarely see measures of cost growth that account for both effects. To fill this gap, we present the quality-adjusted cost of care, which illustrates cost growth net of growth in the value of health improvements, measured as survival gains multiplied by the value of survival. We applied the quality-adjusted cost of care to two cases. For colorectal cancer, drug cost per patient increased by $34,493 between 1998 and 2005 as a result of new drug launches, but value from offsetting health improvements netted a modest $1,377 increase in quality-adjusted cost of care. For multiple myeloma, new therapies increased treatment cost by $72,937 between 2004 and 2009, but offsetting health benefits lowered overall quality-adjusted cost of care by $67,863. However, patients with multiple myeloma on established first-line therapies saw costs rise without corresponding benefits. All three examples document rapid cost growth, but they provide starkly different answers to the question of whether society got what it paid for.

  7. Social Security cost-of-living adjustments and the Consumer Price Index.

    Science.gov (United States)

    Burdick, Clark; Fisher, Lynn

    2007-01-01

    OASDI benefits are indexed for inflation to protect beneficiaries from the loss of purchasing power implied by inflation. In the absence of such indexing, the purchasing power of Social Security benefits would be eroded as rising prices raise the cost of living. By statute, cost-of-living adjustments (COLAs) for Social Security benefits are calculated using the Bureau of Labor Statistics (BLS) Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W). Some argue that this index does not accurately reflect the inflation experienced by the elderly population and should be changed to an elderly-specific price index such as the Experimental Consumer Price Index for Americans 62 Years of Age and Older, often referred to as the Consumer Price Index for the Elderly (CPI-E). Others argue that the measure of inflation underlying the COLA is technically biased, causing it to overestimate changes in the cost of living. This argument implies that current COLAs tend to increase, rather than merely maintain, the purchasing power of benefits over time. Potential bias in the CPI as a cost-of-living index arises from a number of sources, including incomplete accounting for the ability of consumers to substitute goods or change purchasing outlets in response to relative price changes. The BLS has constructed a new index called the Chained Consumer Price Index for All Urban Consumers (C-CPI-U) that better accounts for those consumer adjustments. Price indexes are not true cost-of-living indexes, but approximations of cost-of-living indexes (COLI). The Bureau of Labor Statistics (2006a) explains the difference between the two: As it pertains to the CPI, the COLI for the current month is based on the answer to the following question: "What is the cost, at this month ' market prices, of achieving the standard of living actually attained in the base period?" This cost is a hypothetical expenditure-the lowest expenditure level necessary at this month's prices to achieve the

  8. Increasing the Benefit from Cost-Minimizing Loads via Centralized Adjustments

    Full Text Available Several demand response (DR strategies rely on real-time pricing and selfish local optimization, which may not result in optimal electricity consumption patterns from the viewpoint of an energy supplier or a power system. Thus, this paper proposes a strategy enabling centralized adjustments to cost-minimize consumers’ load. By employing the strategy, an aggregator is able to alter electricity consumption in order to remove power imbalances and to participate in the balancing power market (BPM. In this paper, we focus on direct electric space heating (DESH loads that aim to minimize their heating cost locally. The consumers and an aggregator agree about an indoor temperature band, within which the aggregator is allowed to alter the temperature, and thus the electricity consumption. Centrally, the aggregator procures its electricity demand from a day-ahead (DA market by utilizing the allowed temperature band and employs the band later in real-time (RT operation for the balancing of its own imbalances or regulating power in the BPM.

    Cochlear implantation (CI) is a common intervention for severe-to-profound hearing loss in high-income countries, but is not commonly available to children in low resource environments. Owing in part to the device costs, CI has been assumed to be less economical than deaf education for low resource countries. The purpose of this study is to compare the cost effectiveness of the two interventions for children with severe-to-profound sensorineural hearing loss (SNHL) in a model using disability adjusted life years (DALYs). Cost estimates were derived from published data, expert opinion, and known costs of services in Nicaragua. Individual costs and lifetime DALY estimates with a 3% discounting rate were applied to both two interventions. Sensitivity analysis was implemented to evaluate the effect on the discounted cost of five key components: implant cost, audiology salary, speech therapy salary, number of children implanted per year, and device failure probability. The costs per DALY averted are $5,898 and $5,529 for CI and deaf education, respectively. Using standards set by the WHO, both interventions are cost effective. Sensitivity analysis shows that when all costs set to maximum estimates, CI is still cost effective. Using a conservative DALY analysis, both CI and deaf education are cost-effective treatment alternatives for severe-to-profound SNHL. CI intervention costs are not only influenced by the initial surgery and device costs but also by rehabilitation costs and the lifetime maintenance, device replacement, and battery costs. The major CI cost differences in this low resource setting were increased initial training and infrastructure costs, but lower medical personnel and surgery costs.

    2016-02-18

    To compare reverse-total shoulder arthroplasty (RSA) cost-effectiveness with total hip arthroplasty cost-effectiveness. This study used a stochastic model and decision-making algorithm to compare the cost-effectiveness of RSA and total hip arthroplasty. Fifteen patients underwent pre-operative, and 3, 6, and 12 mo post-operative clinical examinations and Short Form-36 Health Survey completion. Short form-36 Health Survey subscale scores were converted to EuroQual Group Five Dimension Health Outcome scores and compared with historical data from age-matched patients who had undergone total hip arthroplasty. Quality-adjusted life year (QALY) improvements based on life expectancies were calculated. The cost/QALY was $3900 for total hip arthroplasty and $11100 for RSA. After adjusting the model to only include shoulder-specific physical function subscale items, the RSA QALY improved to 2.8 years, and its cost/QALY decreased to $8100. Based on industry accepted standards, cost/QALY estimates supported both RSA and total hip arthroplasty cost-effectiveness. Although total hip arthroplasty remains the quality of life improvement "gold standard" among arthroplasty procedures, cost/QALY estimates identified in this study support the growing use of RSA to improve patient quality of life.

    2014-01-01

    The impact of administrative costs on the distribution of terminal wealth is approximated using a simple formula applicable to many investment situations. We show that the reduction in median returns attributable to administrative fees is usually at least twice the amount of the administrative costs charged for most investment funds, when considering a risk-adjustment correction over a reasonably long-term time horizon. The example we present covers a number of standard cases and can be applied to passive investments, mutual funds, and hedge funds. Our results show investors the potential losses they face in performance due to administrative costs.

    2007-09-01

    The objectives of this study were to develop a risk-adjusted model to estimate individual postoperative costs after major lung resection and to use it for internal economic audit. Variable and fixed hospital costs were collected for 679 consecutive patients who underwent major lung resection from January 2000 through October 2006 at our unit. Several preoperative variables were used to develop a risk-adjusted econometric model from all patients operated on during the period 2000 through 2003 by a stepwise multiple regression analysis (validated by bootstrap). The model was then used to estimate the postoperative costs in the patients operated on during the 3 subsequent periods (years 2004, 2005, and 2006). Observed and predicted costs were then compared within each period by the Wilcoxon signed rank test. Multiple regression and bootstrap analysis yielded the following model predicting postoperative cost: 11,078 + 1340.3X (age > 70 years) + 1927.8X cardiac comorbidity - 95X ppoFEV1%. No differences between predicted and observed costs were noted in the first 2 periods analyzed (year 2004, $6188.40 vs $6241.40, P = .3; year 2005, $6308.60 vs $6483.60, P = .4), whereas in the most recent period (2006) observed costs were significantly lower than the predicted ones ($3457.30 vs $6162.70, P model may be used as a methodologic template for economic audit in our specialty and complement more traditional outcome measures in the assessment of performance.

    2016-05-01

    To develop a clinically risk-adjusted financial model to estimate the cost associated with a video-assisted thoracoscopic surgery (VATS) lobectomy programme. Prospectively collected data of 236 VATS lobectomy patients (August 2012-December 2013) were analysed retrospectively. Fixed and variable intraoperative and postoperative costs were retrieved from the Hospital Accounting Department. Baseline and surgical variables were tested for a possible association with total cost using a multivariable linear regression and bootstrap analyses. Costs were calculated in GBP and expressed in Euros (EUR:GBP exchange rate 1.4). The average total cost of a VATS lobectomy was €11 368 (range €6992-€62 535). Average intraoperative (including surgical and anaesthetic time, overhead, disposable materials) and postoperative costs [including ward stay, high dependency unit (HDU) or intensive care unit (ICU) and variable costs associated with management of complications] were €8226 (range €5656-€13 296) and €3029 (range €529-€51 970), respectively. The following variables remained reliably associated with total costs after linear regression analysis and bootstrap: carbon monoxide lung diffusion capacity (DLCO) 0.05) in 86% of the samples. A hypothetical patient with COPD and DLCO less than 60% would cost €4270 more than a patient without COPD and with higher DLCO values (€14 793 vs €10 523). Risk-adjusting financial data can help estimate the total cost associated with VATS lobectomy based on clinical factors. This model can be used to audit the internal financial performance of a VATS lobectomy programme for budgeting, planning and for appropriate bundled payment reimbursements. © The Author 2015.

  1. Electric infrastructure failures in Nigeria: a survey-based analysis of the costs and adjustment responses

    International Nuclear Information System (INIS)

    Adenikinju, A.F.

    2003-01-01

    This paper examines the cost of electricity shortages on the Nigerian manufacturing sector. Utilizing the data obtained from a 1998 nationwide survey, the paper details the various costs from power outages and examines the response of manufacturers to the infrastructure problem. The findings of the study confirm that the cost of electricity failures on the Nigerian manufacturing sector is quite high. Firms incur huge costs on the provision of expensive back-up to minimise the expected outage costs. The average costs of this back-up are on the average 3 times the cost of publicly supplied electricity. The marginal cost estimates also indicate that the cost of kWh of unserved electricity in Nigeria is very high. Small-scale firms bear the greater proportion of the cost of the power failure. A situation where firms spend as much as 20-30% of initial investment on the acquisition of facilities to enhance electricity supply reliability has a significant negative impact on costs competitiveness of the manufacturing sector. Thus, the study supports current government efforts to privatise the public monopoly and liberalizes the electricity market. These hopefully will mitigate the burden of poor power supply as well as introduce the needed competition into the electricity market in the country

  2. The cost-effectiveness of laparoscopic adjustable gastric banding in the morbidly obese adult population of Australia.

    Directory of Open Access Journals (Sweden)

    Yong Yi Lee

    Full Text Available BACKGROUND: To examine the cost-effectiveness of providing laparoscopic adjustable gastric banding (LAGB surgery to all morbidly obese adults in the 2003 Australian population. METHODS AND FINDINGS: Analyzed costs and benefits associated with two intervention scenarios, one providing LAGB surgery to individuals with BMI >40 and another to individuals with BMI >35, with each compared relative to a 'do nothing' scenario. A multi-state, multiple cohort Markov model was used to determine the cost-effectiveness of LAGB surgery over the lifetime of each cohort. All costs and health outcomes were assessed from an Australian health sector perspective and were discounted using a 3% annual rate. Uncertainty and sensitivity analyzes were conducted to test the robustness of model outcomes. Incremental cost-effectiveness ratios (ICERs were measured in 2003 Australian dollars per disability adjusted life year (DALY averted. The ICER for the scenario providing LAGB surgery to all individuals with a BMI >40 was dominant [95% CI: dominant -$588] meaning that the intervention led to both improved health and cost savings. The ICER when providing surgery to those with a BMI >35 was $2,154/DALY averted [95% CI: dominant -$6,033]. Results were highly sensitive to changes in the likelihood of long-term complications. CONCLUSION: LAGB surgery is highly cost-effective when compared to the $50,000/DALY threshold for cost-effectiveness used in Australia. LAGB surgery also ranks highly in terms of cost-effectiveness when compared to other population-level interventions for weight loss in Australia. The results of this study are in line with other economic evaluations on LAGB surgery. This study recommends that the Australian federal government provide a full subsidy for LAGB surgery to morbidly obese Australians with a BMI >40.

    2014-01-01

    What effect did the introduction of the Employment Tax Incentive (ETI) have on youth employment probabilities in South Africa in the short run? The ETI came into effect on the 1st of January 2014. Its purpose is to stimulate youth employment levels and ease the challenges that many youth experience in finding their first jobs. Under the ETI, firms that employ youth are eligible to claim a deduction from their taxes due, for the portion of their wage bill that is paid to certain groups of yout...

  8. Intra-industry adjustment to import competition: theory and application to the German clothing industry

    2009-01-01

    This paper uses an oligopoly model with heterogeneous firms to examine how an industry adjusts to rising import competition. The model predicts that in the short run the least efficient firms in the industry become inactive, surviving firms face a fall in output, mark-ups and profits, and the average productivity of survivors increases. These pro-competitive effects of import penetration on the domestic industry disappear in the long run. The predictions for the short run are confirmed in an ...

    Oil production by means of sucker rod pumping units is the oldest and most frequently used method. Adjusting the counterweight to reduce the torque at the gearbox is still a significant problem. Depending on the procedure, counterbalancing produces various costs due to the manhours necessary. Because the often-used procedures are very time-consuming, in the past a precise positioning of the counterweight is often put aside. This, however, can lead to the risk of much higher costs as a result of gearbox damage. Providing a simple and time-saving method of adjusting the counterweight is therefore of greatest importance to all users. In this article a PC-program is developed, which is easy to handle and needs no expensive hardware. Compared to other methods, the here decribed program reduces the costs for the correct adjustment of the counterweight on average by around 60%. Finally, very simple steps to reduce costs, while running sucker rod pumping units are explained. (orig.)

In diesem Beitrag wird ein PC-Programm vorgestellt, das besonders einfach zu bedienen ist und keine teuren Geraete erfordert. Gegenueber den messtechnischen Methoden koennen durch die Verwendung dieses Programmes die Kosten fuer eine Gegengewichtseinstellung um durchschnittlich 60% gesenkt werden. Abschliessend werden einfache, in der Praxis leicht realisierbare Massnahmen zur Kostenreduktion beim Betrieb von Tiefpumpenantrieben vorgestellt. (orig.)

    The purchasing power parity theory says that the trade rates among two nations ought to be equivalent to the proportion of the total price levels between the two nations. For more than a decade, there has been substantial interest in testing for the validity of the Purchasing Power Parity (PPP) empirically. This paper performs a series of tests to see if PPP is valid for ASEAN-5 nations for the period of 2000-2016 using monthly data. For this purpose, we conducted four different tests of stationarity, two cointegration tests (Pedroni and Westerlund), and also the VAR model. The stationarity (unit root) tests reveal that the variables are not stationary at levels however stationary at first difference. Cointegration test results did not reject the H0 of no cointegration implying the absence long-run association among the variables and results of the VAR model did not reveal a strong short-run relationship. Based on the data, we, therefore, conclude that PPP is not valid in long-and short-run for ASEAN-5 during 2000-2016.

    Riordan, B.J.

    1986-03-01

    This report develops quantitative labor productivity adjustment factors for the performance of regulatory impact analyses (RIAs). These factors will allow analysts to modify ''new construction'' labor costs to account for changes in labor productivity due to differing work environments at operating reactors and at reactors with construction in progress. The technique developed in this paper relies on the Energy Economic Data Base (EEDB) for baseline estimates of the direct labor hours and/or labor costs required to perform specific tasks in a new construction environment. The labor productivity cost factors adjust for constraining conditions such as working in a radiation environment, poor access, congestion and interference, etc., which typically occur on construction tasks at operating reactors and can occur under certain circumstances at reactors under construction. While the results do not portray all aspects of labor productivity, they encompass the major work place conditions generally discernible by the NRC analysts and assign values that appear to be reasonable within the context of industry experience. 18 refs

    Full Text Available Purpose: The stable relationship of one-supplier-one-customer is replaced by a dynamic relationship of multi-supplier-multi-customer in current market gradually, and efficient scheduling techniques are important tools of the dynamic supply chain relationship establishing process. This paper studies the optimization of the integrated planning and scheduling problem of a two-stage supply chain with multiple manufacturers and multiple retailers to obtain a minimum supply chain operating cost, whose manufacturers have different production capacities, holding and producing cost rates, transportation costs to retailers.Design/methodology/approach: As a complex task allocation and scheduling problem, this paper sets up an INLP model for it and designs a Unit Cost Adjusting (UCA heuristic algorithm that adjust the suppliers’ supplying quantity according to their unit costs step by step to solve the model.Findings: Relying on the contrasting analysis between the UCA and the Lingo solvers for optimizing many numerical experiments, results show that the INLP model and the UCA algorithm can obtain its near optimal solution of the two-stage supply chain’s planning and scheduling problem within very short CPU time.Research limitations/implications: The proposed UCA heuristic can easily help managers to optimizing the two-stage supply chain scheduling problems which doesn’t include the delivery time and batch of orders. For two-stage supply chains are the most common form of actual commercial relationships, so to make some modification and study on the UCA heuristic should be able to optimize the integrated planning and scheduling problems of a supply chain with more reality constraints.Originality/value: This research proposes an innovative UCA heuristic for optimizing the integrated planning and scheduling problem of two-stage supply chains with the constraints of suppliers’ production capacity and the orders’ delivering time, and has a great

    We have designed and fabricated a miniature microscope from off-the-shelf components and webcam, with built-in fluorescence capability for biomedical applications. The mini-microscope was able to detect both biochemical parameters such as cell/tissue viability (e.g. Live/Dead assay), and biophysical properties of the microenvironment such as oxygen levels in microfabricated tissues based on an oxygen-sensitive fluorescent dye. This mini-microscope has adjustable magnifications from 8-60X, achieves a resolution as high as microscope was able to chronologically monitor cell migration and analyze beating of microfluidic liver and cardiac bioreactors in real time, respectively. The mini-microscope system is cheap, and its modularity allows convenient integration with a wide variety of pre-existing platforms including but not limited to, cell culture plates, microfluidic devices, and organs-on-a-chip systems. Therefore, we envision its widespread applications in cell biology, tissue engineering, biosensing, microfluidics, and organs-on-chips, which can potentially replace conventional bench-top microscopy where long-term in situ and large-scale imaging/analysis is required.

    To reapportion Veterans Health Administration (VA) annual expenditures into benefit categories for comparison with estimated payments by private sector providers. Total expenditures for six VA medical centers for federal fiscal year 1999 were reapportioned by benefit category using the cost distribution report (CDR). Health benefit categories were based on those of health care insurers. Cost reapportionment was based on CDR data and reviews of source accounting and payroll documents. Actual expenditures for many benefits can be accurately identified and reapportioned using CDR data, but other expenditures were not identifiable in the CDR and required inspection of source documents. Inpatient expenditures amounting to $75,110,094 US dollars and outpatient expenditures amounting to $73,594,284 US dollars were reapportioned into other benefit categories, primarily professional fees. Expenditures for some VA benefits could not be identified because of differences in accounting and clinical practice between the VA and the community. Revisions to bring the CDR more in line with private sector payment categories would improve effectiveness for internal VA analyses and external expenditure comparisons. CDR revisions would require changes in recording some clinical workload (eg, rehabilitation and extended care) and classifying residential and domiciliary programs separate from inpatient care. Benefits that were not assigned expenditures for comparison with payments represent a potential liability if the VA were to purchase health care services in the marketplace. Variation among hospitals on expenditures not clearly identified in the CDR was significant and raises questions about the effectiveness of capitated budget methodologies using either the CDR or the decision support system.

  16. Adjusting patients streaming initiated by a wait time threshold in emergency department for minimizing opportunity cost.

    2017-07-10

    Purpose Two different systems for streaming patients were considered to improve efficiency measures such as waiting times (WTs) and length of stay (LOS) for a current emergency department (ED). A typical fast track area (FTA) and a fast track with a wait time threshold (FTW) were designed and compared effectiveness measures from the perspective of total opportunity cost of all patients' WTs in the ED. The paper aims to discuss these issues. Design/methodology/approach This retrospective case study used computerized ED patient arrival to discharge time logs (between July 1, 2009 and June 30, 2010) to build computer simulation models for the FTA and fast track with wait time threshold systems. Various wait time thresholds were applied to stream different acuity-level patients. National average wait time for each acuity level was considered as a threshold to stream patients. Findings The fast track with a wait time threshold (FTW) showed a statistically significant shorter total wait time than the current system or a typical FTA system. The patient streaming management would improve the service quality of the ED as well as patients' opportunity costs by reducing the total LOS in the ED. Research limitations/implications The results of this study were based on computer simulation models with some assumptions such as no transfer times between processes, an arrival distribution of patients, and no deviation of flow pattern. Practical implications When the streaming of patient flow can be managed based on the wait time before being seen by a physician, it is possible for patients to see a physician within a tolerable wait time, which would result in less crowded in the ED. Originality/value A new streaming scheme of patients' flow may improve the performance of fast track system.

  17. The Cost of Being Cool: How Adolescent Pseudomature Behavior Maps onto Adult Adjustment.

    During adolescence, one's status among peers is a major concern. Such status is often largely a function of popularity and establishing oneself as "cool." While there are conventional avenues to achieving status among adolescents, engaging in adult-like, or pseudomature, behaviors such as substance use or sexual activity is a frequent occurrence. Although past research has examined the consequences of adolescent delinquency, what remains unclear is the long-term fate of adolescents who are both popular and antisocial. Using data from a sample of African American males (N = 339) we employ latent class analysis to examine the adult consequences of achieving popularity during adolescence by engaging in pseudomature behavior. Our results identified four classes of adolescents: the conventionals, the pseudomatures, the delinquents, and the detached. The conventionals were low on popularity, pseudomature behavior, and affiliation with deviant peers but high on academic commitment. The pseudomatures were high on popularity, adult-like behavior, and academic commitment but low on affiliation with delinquent peers. The delinquents were low on popularity and school achievement but high on pseudomature behavior and affiliations with delinquent peers. Finally, the detached were low on school commitment, popularity and pseudomature behavior but they report high involvement with a delinquent peer group. By early adulthood, the costs of adolescent adult-like behavior were evident. Early popularity and academic commitment did not portend later social competence or college completion for the pseudomatures. Instead, they frequently experienced an early transition to parenthood, a likely consequence of precocious sexual activity. These findings suggest that interventions should not focus only on the most delinquent adolescents but also need to attend to the pseudomature students who are brimming with promise but are flirting with behaviors that may subvert realization of this

    This study estimates the annual numbers of eight work-related cancers, total losses of quality-adjusted life years (QALYs), and lifetime healthcare expenditures that possibly could be saved by improving occupational health in Taiwan. Three databases were interlinked: the Taiwan Cancer Registry, the National Mortality Registry, and the National Health Insurance Research Database. Annual numbers of work-related cancers were estimated based on attributable fractions (AFs) abstracted from a literature review. The survival functions for eight cancers were estimated and extrapolated to lifetime using a semi-parametric method. A convenience sample of 8846 measurements of patients' quality of life with EQ-5D was collected for utility values and multiplied by survival functions to estimate quality-adjusted life expectancies (QALEs). The loss-of-QALE was obtained by subtracting the QALE of cancer from age- and sex-matched referents simulated from national vital statistics. The lifetime healthcare expenditures were estimated by multiplying the survival probability with mean monthly costs paid by the National Health Insurance for cancer diagnosis and treatment and summing this for the expected lifetime. A total of 3010 males and 726 females with eight work-related cancers were estimated in 2010. Among them, lung cancer ranked first in terms of QALY loss, with an annual total loss-of-QALE of 28,463 QALYs and total lifetime healthcare expenditures of US$36.6 million. Successful prevention of eight work-related cancers would not only avoid the occurrence of 3736 cases of cancer, but would also save more than US$70 million in healthcare costs and 46,750 QALYs for the Taiwan society in 2010.

    While countries with higher levels of human resources for health typically have better population health, the evidence that increases in the level of human resources for health leads to improvements in population health is limited. We use a dynamic regression model to obtain estimates of both the short-run and long-term effects of changes in physicians per capita, our measure of health system resources, on infant mortality. Using a dataset of 99 countries at 5-year intervals from 1960-2000, we estimate that increasing the number of physicians by one per 1000 population (roughly a doubling of current levels of provision) decreases the infant mortality rate by 15% within 5 years and by 45% in the long-run with half the long-run gain being achieved in 15 years. We conclude that the long-run effects of heath system resources are substantially larger than previously estimated. Our results suggest, however, that countries that have delayed action on the Millennium Development Goal of reducing infant and child mortality rate by two-thirds by 2015 (relative to 1990) may have difficulty meeting this goal even if they rapidly increase resources now.

    Full Text Available The focus of this research was to investigate the short-term influence of U.S. crude oil inventories on WTI crude oil prices from 1993 to 2013. This study is important for policy makers who wish to reduce the persistent and growing price volatility of crude oil and its related products as well as businesses such as airline companies who wish to make annual budgetary sales decisions. Using OLS multiple regression, cointegration, VECM and Ex-post forecast techniques; we provide evidence of an inelastic relationship in which a 1% increase in U.S. crude oil inventories is associated with 0.46% decrease in WTI crude oil prices; however this was only valid for 22% of WTI crude oil price variation. We also find that past data on U.S. crude oil inventories could be used to predict future WTI crude oil prices movement. Contrary to literature, the results of the VECM analysis indicate there is no short-run relationship between both variables over the trajectory.

  2. Manage costs and revenues by achieving continuous measurement certainty with the Auto-Adjust Turbo Meter; Gerez les couts et les recettes en acquerant une certitude continuelle de mesure grace au Auto-Adjust Turbo Meter

    Uncertainty in flow measurement and its consequent ramifications are accepted as normal costs of transporting and distributing natural gas. However, a notable advancement in turbine meter technology, pioneered by Invensys Energy Metering, uses two rotors in a tandem configuration to offer unique capabilities beyond those of the tried-and-proven, single-rotor turbine. A flow meter, which monitors its own performance and adjusts its measurement, on a real-time basis, for any deviations from its initial calibration, could largely eliminate many of the costs and lost revenue associated with flow metering and measurement uncertainty. The dual-rotor turbine, trade named the Auto-Adjust Turbo Meter (AAT), is such a flow meter; it provides Continuous Measurement Certainty, with the accompanying potential for enhanced management of costs and revenues. Proprietary algorithms in the AAT's secondary electronics correlate the velocities of the main rotor and the downstream sensing rotor, over the full range of the meter's rated capacity and pressure, such that a real-time adjustment to the indicated volume corrects it to the actual volume. Improved gas accountability results, and substantial savings related to meter site visits, meter testing and repair, preventive maintenance programs, and measurement disputes can be realized. Test data and case histories from a broad range of end users are related to demonstrate areas of potential savings and revenue recovery. (author)

    Cognitive Behavioural Therapy (CBT) reduces distress in multiple sclerosis, and helps manage adjustment, but cost-effectiveness evidence is lacking. An economic evaluation was conducted within a multi-centre trial. 94 patients were randomised to either eight sessions of nurse-led CBT or supportive listening (SL). Costs were calculated from the health, social and indirect care perspectives, and combined with additional quality-adjusted life years (QALY) or improvement on the GHQ-12 score, to explore cost-effectiveness at 12 months. CBT had higher mean health costs (£1610, 95% CI, -£187 to 3771) and slightly better QALYs (0.0053, 95% CI, -0.059 to 0.103) compared to SL but these differences were not statistically significant. This yielded £301,509 per QALY improvement, indicating that CBT is not cost-effective according to established UK NHS thresholds. The extra cost per patient improvement on the GHQ-12 scale was £821 from the same perspective. Using a £20,000, threshold, CBT in this format has a 9% probability of being cost effective. Although subgroup analysis of patients with clinical levels of distress at baseline showed an improvement in the position of CBT compared to SL, CBT was still not cost-effective. Nurse delivered CBT is more effective in reducing distress among MS patients compared to SL, but is highly unlikely to be cost-effective using a preference-based measure of health (EQ-5D). Results from a disease-specific measure (GHQ-12) produced comparatively lower Incremental Cost-Effectiveness Ratios, but there is currently no acceptable willingness-to-pay threshold for this measure to guide decision-making.

  4. A new methodology for cost-effectiveness studies of domestic radon remediation programmes: Quality-adjusted life-years gained within Primary Care Trusts in Central England

    Radon is a naturally occurring radioactive gas, high levels of which are associated with geological formations such as those found in Northamptonshire and North Oxfordshire in the UK. The UK's National Radiological Protection Board have designated both districts as radon Affected Areas. Radiation levels due to radon, therefore, exceed 200 Bq m -3 , the UK's domestic Action Level, in over one percent of domestic properties. Because of radon's radioactivity, exposure to the gas can potentially cause lung cancer, and has been linked to some 2000 deaths a year in the UK. Consequently, when radiation levels exceed the Action Level, remediation against radon's effects is recommended to householders. This study examines the cost-effectiveness of remediation measures in Northamptonshire and North Oxfordshire by estimating cost per quality-adjusted life-year gained in four Primary Care Trusts, organisations that play a key public health policy role in the UK's National Health Service. The study is the first to apply this approach to estimating the cost-effectiveness of radon remediation programmes. Central estimates of cost per quality-adjusted life-year in the four Primary Care Trusts range from Pounds 6143 to Pounds 10 323. These values, when assessed against generally accepted criteria, suggest the remediation programmes in the trusts were cost-effective. Policy suggestions based on the estimates, and designed to improve cost-effectiveness further, are proposed for the four Primary Care Trusts and the UK's National Health Service

    In cost-effectiveness analyses in healthcare, Quality-Adjusted Life Years are often used as outcome measure of effectiveness. However, there is an ongoing debate concerning the appropriateness of its use for decision-making in palliative care. To systematically map pros and cons of using the Quality-Adjusted Life Year to inform decisions on resource allocation among palliative care interventions, as brought forward in the debate, and to discuss the Quality-Adjusted Life Year's value for palliative care. The integrative review method of Whittemore and Knafl was followed. Theoretical arguments and empirical findings were mapped. A literature search was conducted in PubMed, EMBASE, and CINAHL, in which MeSH (Medical Subject Headings) terms were Palliative Care, Cost-Benefit Analysis, Quality of Life, and Quality-Adjusted Life Years. Three themes regarding the pros and cons were identified: (1) restrictions in life years gained, (2) conceptualization of quality of life and its measurement, including suggestions to adapt this, and (3) valuation and additivity of time, referring to changing valuation of time. The debate is recognized in empirical studies, but alternatives not yet applied. The Quality-Adjusted Life Year might be more valuable for palliative care if specific issues are taken into account. Despite restrictions in life years gained, Quality-Adjusted Life Years can be achieved in palliative care. However, in measuring quality of life, we recommend to-in addition to the EQ-5D- make use of quality of life or capability instruments specifically for palliative care. Also, we suggest exploring the possibility of integrating valuation of time in a non-linear way in the Quality-Adjusted Life Year.

    New direct-acting antiviral (DAA) therapy has dramatically increased cure rates for patients infected with hepatitis C virus (HCV), but has also substantially raised treatment costs. The aim of this analysis was to evaluate the therapeutic benefit and net costs (i.e. efficiency frontier) and the quality-adjusted cost of care associated with the evolution of treatment regimens for patients with HCV genotype 1 in the United States. A decision-analytic Markov model. Published literature and clinical trial data. Life Time. Third-party payer. This study compared four approved regimens in treatment-naïve genotype 1 chronic hepatitis C patients, including pegylated interferon and ribavirin (PR), first generation triple therapy (boceprevir + PR and telaprevir + PR), second generation triple therapy (sofosbuvir + PR and simeprevir + PR) and all-oral DAA regimens (ledipasvir/sofosbuvir and ombitasvir + paritaprevir/ritonavir + dasabuvir ± ribavirin). Quality-adjusted cost of care (QACC). QACC was defined as the increase in treatment cost minus the increase in the patient's quality-adjusted life years (QALYs) when valued at $50,000 per QALY. All-oral therapy improved the average sustained virologic response (SVR) rate to 96%, thereby offsetting the high drug acquisition cost of $85,714, which resulted in the highest benefit based on the efficiency frontier. Furthermore, while oral therapies increased HCV drug costs by $48,350, associated QALY gains decreased quality-adjusted cost of care by $14,120 compared to dual therapy. When the value of a QALY was varied from $100,000 to $300,000, the quality adjusted cost of care compared to dual therapy ranged from - $21,234 to - $107,861, - $89,007 to - $293,130, - $176,280 to - $500,599 for first generation triple, second generation triple, and all-oral therapies, respectively.

    Uncertainty exists regarding appropriate and affordable use of adjuvant chemotherapy in stage II colon cancer (T3, proficient DNA mismatch repair). This study aimed to estimate the effectiveness and costs from a US societal perspective of a multigene recurrence score (RS) assay for patients recently diagnosed with stage II colon cancer (T3, proficient DNA mismatch repair) eligible for adjuvant chemotherapy. RS was compared with guideline-recommended clinicopathological factors (tumor stage, lymph nodes examined, tumor grade, and lymphovascular invasion) by using a state-transition (Markov) lifetime model. Data were obtained from published literature, a randomized controlled trial (QUick And Simple And Reliable) of adjuvant chemotherapy, and rates of chemotherapy use from the National Cooperative Cancer Network Colon/Rectum Cancer Outcomes study. Life-years, quality-adjusted life expectancy, and lifetime costs were examined. The RS is projected to reduce adjuvant chemotherapy use by 17% compared with current treatment patterns and to increase quality-adjusted life expectancy by an average of 0.035 years. Direct medical costs are expected to decrease by an average of $2971 per patient. The assay was cost saving for all subgroups of patients stratified by clinicopathologic factors. The most influential variables affecting treatment decisions were projected years of life remaining, recurrence score, and patients' disutilities associated with adjuvant chemotherapy. Use of the multigene RS to assess recurrence risk after surgery in stage II colon cancer (T3, proficient DNA mismatch repair) may reduce the use of adjuvant chemotherapy without decreasing quality-adjusted life expectancy and be cost saving from a societal perspective. These findings need to be validated in additional cohorts, including studies of clinical practice as assay use diffuses into nonacademic settings.

    Benchmarking is a proven and widely used business tool for identifying best practice. To produce robust results, the objects of comparison used in benchmarking analysis need to be structurally comparable and distorting factors need to be eliminated. We focus on a specific example - a benchmark study commissioned by the European Commission's Directorate-General for Environment on the implementation of Extended Producer Responsibility (EPR) for packaging at the national level - to discuss potential distorting factors and take them into account in the calculation. The cost of compliance per inhabitant and year, which is used as the key cost efficiency indicator in the study, is adjusted to take account of seven factors. The results clearly show that differences in performance may play a role, but the (legal) implementation of EPR - which is highly heterogeneous across countries - is the single most important cost determinant and must be taken into account to avoid misinterpretation and false conclusions.

    The study aims to obtain the mean relative weights (MRWs) of the cost of care through the retrospective application of the adjusted clinical groups (ACGs) in several primary health care (PHC) centres in Catalonia (Spain) in routine clinical practice. This is a retrospective study based on computerized medical records. All patients attended by 13 PHC teams in 2008 were included. The principle measurements were: demographic variables (age and sex), dependent variables (number of diagnoses and total costs), and case-mix or co-morbidity variables (International Classification of Primary Care). The costs model for each patient was established by differentiating the fix costs from the variable costs. In the bivariate analysis, the Student's t, analysis of variance, chi-squared, Pearson's linear correlation and Mann-Whitney-Wilcoxon tests were used. In order to compare the MRW of the present study with those of the United States (US), the concordance [intraclass correlation coefficient (ICC) and concordance correlation coefficient (CCC)] and the correlation (coefficient of determination: R²) were measured. The total number of patients studied was 227,235, and the frequentation was 5.9 visits/habitant/year) and with a mean diagnoses number of 4.5 (3.2). The distribution of costs was €148.7 million, of which 29.1% were fixed costs. The mean total cost per patient/year was €654.2 (851.7), which was considered to be the reference MRW. Relationship between study-MRW and US-MRW: ICC was 0.40 [confidential interval (CI) 95%: 0.21-0.60] and the CCC was 0.42 (CI 95%: 0.35-0.49). The correlation between the US MRW and the MRW of the present study can be seen; the adjusted R² value is 0.691. The explanatory power of the ACG classification was 36.9% for the total costs. The R² of the total cost without considering outliers was 56.9%. The methodology has been shown appropriate for promoting the calculation of the MRW for each category of the classification. The results provide

    To assess the return on investment (ROI) and economic impact of providing insurance coverage for the laparoscopic adjustable gastric banding (LAGB) procedure in classes II and III obese members of the Texas Employees Retirement System (ERS) and their dependents from payer, employer, and societal perspectives. Classes II and III obese employee members and their adult dependents were identified in a Texas ERS database using self-reported health risk assessment (HRA) data. Direct health costs and related absenteeism and mortality losses were estimated using data from previous research. A dynamic input-output model was then used to calculate overall economic effects by incorporating direct, indirect, and induced impacts. Direct health costs were inflation-adjusted to 2008 US dollars using the Consumer Price Index for Medical Care and other spending categories were similarly adjusted using relevant consumer and industrial indices. The future cost savings and other monetary benefits were discounted to present value using a real rate of 4.00%. From the payer perspective (ERS), the payback period for direct health costs associated with the LAGB procedure was 23-24 months and the annual return (over 5 years) was 28.8%. From the employer perspective (State of Texas), the costs associated with the LAGB procedure were recouped within 17-19 months (in terms of direct, indirect, and induced gains as they translated into State revenue) and the annual return (over 5 years) was 45.5%. From a societal perspective, the impact on total business activity for Texas (over 5 years) included gains of $195.3 million in total expenditures, $93.8 million in gross product, and 1354 person-years of employment. The analysis was limited by the following: reliance on other studies for methodology and use of a control sample; restriction of cost savings to 2.5 years which required out-of-sample forecasting; conservative assumptions related to the cost of the procedure; exclusion of presenteeism

    Obese patients have greater comorbidities along with higher risk of complications and greater costs after spine surgery, which may result in increased cost and lower quality of life compared with their non-obese counterparts. The aim of the present study was to determine cost-utility following anterior cervical discectomy and fusion (ACDF) in obese patients. This study analyzed prospectively collected data. Patients undergoing elective ACDF for degenerative cervical pathology at a single academic institution were included in the study. Cost and quality-adjusted life years (QALYs) were the outcome measures. One- and two-year medical resource utilization, missed work, and health state values (QALYs) were assessed. Two-year resource use was multiplied by unit costs based on Medicare national payment amounts (direct cost). Patient and caregiver workday losses were multiplied by the self-reported gross-of-tax wage rate (indirect cost). Total cost (direct+indirect) was used to compute cost per QALY gained. Patients were defined as obese for body mass index (BMI) ≥35 based on the WHO definition of class II obesity. A subgroup analysis was conducted in morbidly obese patients (BMI≥40). There were significant improvements in pain (neck pain or arm pain), disability (Neck Disability Index), and quality of life (EuroQol-5D and Short Form-12) at 2 years after surgery (pdirect cost, indirect cost, and total cost between obese and non-obese patients at postoperative 1-year and 2-year follow-up. Mean 2-year direct cost for obese patients was $19,225±$8,065 and $17,635±$6,413 for non-obese patients (p=.14). There was no significant difference in the mean total 2-year cost between obese ($23,144±$9,216) and non-obese ($22,183±$10,564) patients (p=.48). Obese patients had a lower mean cumulative gain in QALYs versus non-obese patients at 2-years (0.34 vs. 0.42, p=.32). Two-year cost-utility in obese ($68,070/QALY) versus non-obese patients ($52,816/QALY) was not

    Long-run adjustments in petroleum consumption are not only larger than short-run adjustments. They may also be motivated by entirely different price events. This analysis shows that new price peaks have both short-run and long-run consumption responses, a result that is starkly different than price changes that track previous price paths. It also establishes significant trend effects where gasoline and residual fuel oil consumption decline over time. The analysis explores these adjustments by establishing long-run cointegrating relationships for different petroleum product groupings. An important implication is that price increases above historical levels may be providing substantially greater incentives for significant long-run demand adjustments than would be the case otherwise.

    To describe the adaptive capacity of the Adjusted Clinical Groups (ACG) system to the cost of care in primary healthcare centres in Catalonia (Spain). Retrospective study (multicentres) conducted using computerised medical records. 13 primary care teams in 2008 were included. All patients registered in the study centres who required care between 1 January and 31 December 2008 were finally studied. Patients not registered in the study centres during the study period were excluded. Demographic (age and sex), dependent (cost of care) and case-mix variables were studied. The cost model for each patient was established by differentiating the fixed and variable costs. To evaluate the adaptive capacity of the ACG system, Pearson's coefficient of variation and the percentage of outliers were calculated. To evaluate the explanatory power of the ACG system, the authors used the coefficient of determination (R(2)). The number of patients studied was 227 235 (frequency: 5.9 visits per person per year), with a mean of 4.5 (3.2) episodes and 8.1 (8.2) visits per patient per year. The mean total cost was €654.2. The explanatory power of the ACG system was 36.9% for costs (56.5% without outliers). 10 ACG categories accounted for 60.1% of all cases and 19 for 80.9%. 5 categories represented 71% of poor performance (N=78 887, 34.7%), particularly category 0300-Acute Minor, Age 6+ (N=26 909, 11.8%), which had a coefficient of variation =139% and 6.6% of outliers. The ACG system is an appropriate manner of classifying patients in routine clinical practice in primary healthcare centres in Catalonia, although improvements to the adaptive capacity through disaggregation of some categories according to age groups and, especially, the number of acute episodes in paediatric patients would be necessary to reduce intra-group variation.

    An alternate travel cost model is applied to an on-site sample to estimate the value of flat water recreation on the impounded lower Snake River. Four contiguous reservoirs would be eliminated if the dams are breached to protect endangered Pacific salmon and steelhead trout. The empirical method applies truncated negative binomial regression with adjustment for endogenous stratification. The two-stage decision model assumes that recreationists allocate their time among work and leisure prior to deciding among consumer goods. The allocation of time and money among goods in the second stage is conditional on the predetermined work time and income. The second stage is a disequilibrium labor market which also applies if employers set work hours or if recreationists are not in the labor force. When work time is either predetermined, fixed by contract, or nonexistent, recreationists must consider separate prices and budgets for time and money.

    Full Text Available Abstract Background Stroke poses a growing human and economic burden in South Africa. Excess sugar consumption, especially from sugar-sweetened beverages (SSBs, has been associated with increased obesity and stroke risk. Research shows that price increases for SSBs can influence consumption and modelling evidence suggests that taxing SSBs has the potential to reduce obesity and related diseases. This study estimates the potential impact of an SSB tax on stroke-related mortality, costs and health-adjusted life years in South Africa. Methods A proportional multi-state life table-based model was constructed in Microsoft Excel (2010. We used consumption data from the 2012 South African National Health and Nutrition Examination Survey, previously published own and cross price elasticities of SSBs and energy balance equations to estimate changes in daily energy intake and BMI arising from increased SSB prices. Stroke relative risk, and prevalent years lived with disability estimates from the Global Burden of Disease Study and modelled disease epidemiology estimates from a previous study, were used to estimate the effect of the BMI changes on the burden of stroke. Results Our model predicts that an SSB tax may avert approximately 72 000 deaths, 550 000 stroke-related health-adjusted life years and over ZAR5 billion, (USD400 million in health care costs over 20 years (USD296-576 million. Over 20 years, the number of incident stroke cases may be reduced by approximately 85 000 and prevalent cases by about 13 000. Conclusions Fiscal policy has the potential, as part of a multi-faceted approach, to mitigate the growing burden of stroke in South Africa and contribute to the achievement of the target set by the Department of Health to reduce relative premature mortality (less than 60 years from non-communicable diseases by the year 2020.

    Polymer microneedle arrays (MNAs) have received much attention for their use in transdermal drug delivery and microneedle therapy systems due to the advantages they offer, such as low cost, good mechanical properties, and a versatile choice of materials. Here, we present a simple and cost-effective method for the fabrication of a biodegradable polymer MNA in which the aspect ratio of each microneedle is adjustable using commercially available acupuncture microneedles. In our process, a master template with acupuncture microneedles, whose shape will be the final MNA, was carefully prepared by fixing them onto a plastic substrate with selectively drilled holes which, in turn, determine the aspect ratios of the microneedles. A polylactic acid (PLA; a biodegradable polymer) MNA was fabricated by a micromolding process with a polydimethylsiloxane (PDMS) mold containing the cavity of the microneedles, which was obtained by the PDMS replica molding against the master template. The mechanical force and degradation behavior of the replicated PLA MNA were characterized with the help of a compression test and an accelerated degradation test, respectively. Finally, the transdermal drug delivery performance of the PLA MNA was successfully simulated by two different methods of penetration and staining, using the skin of a pig cadaver. These results indicated that the proposed method can be effectively used for the fabrication of polymer MNAs which can be used in various microneedle applications. (paper)

Staff indexed data and prevention methods (activities, materials. Quality of life (Qol weights were assigned to the PU states. We assessed the costs of activities and materials in the project. A Markov model was built based on effectiveness and cost data, complemented with a probabilistic sensitivity analysis. To illustrate the results of longer term, three scenarios were created in which change in incidence and prevalence measures were (1 not sustained, (2 partially sustained, and (3 completely sustained. Results Incidence of PUs decreased from 15% to 4.5% for the 88 patients. Prevalence decreased from 38.6% to 22.7%. Average Quality of Life (Qol of patients increased by 0.02 Quality Adjusted Life Years (QALYs in two years; healthcare costs increased by €2000 per patient; the Incremental Cost-effectiveness Ratio (ICER was between 78,500 and 131,000 depending on whether the changes in incidence and prevalence of PU were sustained. Conclusions During the QIC PU incidence and prevalence significantly declined. When compared to standard PU care, the QIC was probably more costly and more effective in the short run, but its long-term cost-effectiveness is questionable. The QIC can only be cost-effective if the changes in incidence and prevalence of PU are sustained.

    The issue of sticky prices in U.S. wholesale gasoline market is re-examined allowing for the effect of market structure due to increased market concentration caused by mergers, acquisitions and joint ventures which started in the late 1990s in the U.S. oil industry. I investigate the effects of market structure on the pattern of price adjustment based on the notion that increased market concentration leads to downward price stickiness and asymmetric short run price adjustment in the transmission of crude price changes to wholesale gasoline price. I find that market concentration has an insignificant asymmetric effect on the speed of price adjustment but a significant asymmetric effect on short run price adjustments in the response of wholesale gasoline prices to crude price shocks in three U.S. wholesale markets. Furthermore, the signs on the coefficients of market concentration effects on price dynamics in the models support the assertion that increased market concentration leads to downward price stickiness in only one of the three markets examined. Overall, the results indicate that market structure does not have a strong effect on the dynamics of price adjustment. (author)

    In a rotating fan beam tomographic scanner there is included an adjustable collimator and shutter assembly. The assembly includes a fan angle collimation cylinder having a plurality of different length slots through which the beam may pass for adjusting the fan angle of the beam. It also includes a beam thickness cylinder having a plurality of slots of different widths for adjusting the thickness of the beam. Further, some of the slots have filter materials mounted therein so that the operator may select from a plurality of filters. Also disclosed is a servo motor system which allows the operator to select the desired fan angle, beam thickness and filter from a remote location. An additional feature is a failsafe shutter assembly which includes a spring biased shutter cylinder mounted in the collimation cylinders. The servo motor control circuit checks several system conditions before the shutter is rendered openable. Further, the circuit cuts off the radiation if the shutter fails to open or close properly. A still further feature is a reference radiation intensity monitor which includes a tuning-fork shaped light conducting element having a scintillation crystal mounted on each tine. The monitor is placed adjacent the collimator between it and the source with the pair of crystals to either side of the fan beam

  19. Probabilistic costing of transmission services

    International Nuclear Information System (INIS)

    Wijayatunga, P.D.C.

    1992-01-01

    Costing of transmission services of electrical utilities is required for transactions involving the transport of energy over a power network. The calculation of these costs based on Short Run Marginal Costing (SRMC) is preferred over other methods proposed in the literature due to its economic efficiency. In the research work discussed here, the concept of probabilistic costing of use-of-system based on SRMC which emerges as a consequence of the uncertainties in a power system is introduced using two different approaches. The first approach, based on the Monte Carlo method, generates a large number of possible system states by simulating random variables in the system using pseudo random number generators. A second approach to probabilistic use-of-system costing is proposed based on numerical convolution and multi-area representation of the transmission network. (UK)

  20. The costs of climate policies in a second best world with labour market imperfections

    International Nuclear Information System (INIS)

    Guivarch, C.; Crassous, R.; Sassi, O.; Hallegatte, St.

    2009-09-01

    This article explores the critical role of labour market imperfections in climate stabilisation costs formation. To do so, we use a dynamic recursive energy-economy model that represents a second best world with market imperfections and short-run adjustments constraints along a long-term growth path. We show that the degree of rigidity of the labour markets is a central parameter and we conduct a systematic sensitivity analysis of the model results to this parameter. When labour markets are represented as highly flexible, the model results are in the usual range of existing literature, i.e. less than 2% GDP losses in 2030 for a stabilisation target at 450 ppm CO 2 equivalent, But when labour markets rigidities are accounted for, mitigation costs increase dramatically. In a second time, the article identifies accompanying measures, namely labour subsidies, which guarantees against the risk of large stabilisation costs in the case of high rigidities of the labour markets. That vision complements the usual view that mitigation is a long-term matter that depends on technology, innovation, investment and behavioural change. Here we add the warning that mitigation is also a shorter-term issue and a matter of transition on the labour market. (authors)

    At the end of the year 2006, France proposed the introduction of a 'climatic tariff' into the discussion of the international climatic protection. The 'climatic tariff' shall adjust extra costs, which result from the domestic production by means of environmental protection instruments and to which the import goods are not exposed, with import/export compensatory payments in the form of import duties and/or taxes on import goods. The introduction of an import/export compensatory payment system aims to load imported goods equivalent to domestic products in order to adjust competitive disadvantages. In the contribution under consideration the authors report on possibilities and problems of design for an import/export tax compensatory. The authors examine the validity of the measures of import/export compensation from legal view the World Trade Organization (Geneva, Switzerland) based on the General Agreement on Tariffs and Trade.

Hence, observing frequent price changes is not necessarily inconsistent with a firm operating under menu costs. This paper relies on an article by Dixit (1991), (Review of Economic studies, 58, 141......This paper investigates the effect of uncertainty on a single firm's pricing behaviour in a dynamic menu cost model that results in (S,s)-rules where the price is fixed inside a band.

    This research paper talks about the economic costs of climate change, as well as the costs involved in responding to climate change with alternative fuels. This paper seeks to show that climate change, although seemingly costly in the short run, will both save future generations trillions of dollars and serve as a good economic opportunity. Scientists have long argued that the fate of humanity depends on a shift towards renewable energy. However, this paper will make clear that there is also an economic struggle. By embracing alternative fuels, we will not only lessen the danger and the frequency of these natural disasters but also strengthen the world’s financial state. Although a common argument against responding to climate change is that it is too expensive to make the switch, this research shows that in the future, it will save millions of lives and trillions of dollars. The only question left for policymakers is whether they will grasp this energy source shift.

  5. Marginal cost application in the power industry

    Twardy, L.; Rusak, H.

    1994-01-01

    Two kind of marginal costs, the short-run and the long-run, are defined. The former are applied in conditions when the load increase is not accompanied neither by the increase of the transmission capacity not the installed capacity while the latter assume new investments to expand the power system. The long-run marginal costs be used to forecast optimized development of the system. They contain two main components: the marginal costs of capacity and the marginal costs of energy. When the long-run marginal costs are calculated, each component is considered for particular voltage levels, seasons of the year, hours of the day - selected depending on the system reliability factor as well as on its load level. In the market economy countries the long-run marginal costs can be used for setting up the electric energy tariffs. (author). 7 refs, 11 figs

    Smith, Martin D.; Lynham, John; Sanchirico, James N.; Wilson, James A.

    2010-01-01

    The creation of marine reserves is often controversial. For decisionmakers, trying to find compromises, an understanding of the timing, magnitude, and incidence of the costs of a reserve is critical. Understanding the costs, in turn, requires consideration of not just the direct financial costs but also the opportunity costs associated with reserves. We use a discrete choice model of commercial fishermen’s behavior to examine both the short-run and long-run opportunity costs of marine reserves. Our results can help policymakers recognize the factors influencing commercial fishermen’s responses to reserve proposals. More generally, we highlight the potential drivers behind the political economy of marine reserves. PMID:20133732

    2000-07-01

    Within the context of the IMPOL project several fields of European environmental policy are studied on aspects as national implementation and environmental and efficiency outcomes. For the IMPOL project a case study was done on the transformation of the Dutch sector of domestic waste incineration in the context of the European Directive Directives 89/369/EEC and 89/429/ EEC. The case study was done and indicators for environmental effectiveness, allocative efficiency, productive efficiency and administrative costs were chosen in line with a document to coordinate the efforts in the four IMPOL countries. The European Directives 89/369/EEC and 89/429/ EEC regulate Plants for Domestic waste Incineration on the emissions of several pollutants. These emissions are relevant for air quality in general, acidification and the spreading of toxic substances. In the empirical part of this report emphasis is laid on 'existing' incineration plants, being permitted before 1990. In chapter 2 of this report the implementation of the directives 89/369/EEC and 89/429/EEC in the Netherlands is described. In section 2.1 already existing 'older' Dutch policy and regulation is presented. In paragraph 2.2 the integration of the European Directives into Dutch national law is described. In chapter 2.3 the efforts and outcomes on monitoring and enforcement are presented. Chapter 3 goes into the environmental effectiveness. Section 3.1 describes the abatement performance of the whole municipal waste incineration sector during the period of research. Section 3.2 goes into factors that explain the environmental outcomes. Within the IMPOL research-team the decision was taken to concentrate on a number of pollutants of existing waste incinerators. In section 3.3 the data for the existing incinerators are given. In chapter 4 the allocative efficiency of adjustments is elaborated. In section 4.1 the abatement patterns of existing municipal waste incineration plants are presented

    Particulate air pollution is becoming a serious public health concern in urban cities in India due to air pollution-related health effects associated with disability-adjusted life years (DALYs) and economic loss. To obtain the quantitative result of health impact of particulate matter (PM) in most populated Mumbai City and most polluted Delhi City in India, an epidemiology-based exposure-response function has been used to calculate the attributable number of mortality and morbidity cases from 1991 to 2015 in a 5-year interval and the subsequent DALYs, and economic cost is estimated of the health damage based on unit values of the health outcomes. Here, we report the attributable number of mortality due to PM 10 in Mumbai and Delhi increased to 32,014 and 48,651 in 2015 compared with 19,291 and 19,716 in year 1995. And annual average mortality due to PM 2.5 in Mumbai and Delhi was 10,880 and 10,900. Premature cerebrovascular disease (CEV), ischemic heart disease (IHD), and chronic obstructive pulmonary disease (COPD) causes are about 35.3, 33.3, and 22.9% of PM 2.5 -attributable mortalities. Total DALYs due to PM10 increased from 0.34 million to 0.51 million in Mumbai and 0.34 million to 0.75 million in Delhi from average year 1995 to 2015. Among all health outcomes, mortality and chronic bronchitis shared about 95% of the total DALYs. Due to PM 10 , the estimated total economic cost at constant price year 2005 US$ increased from 2680.87 million to 4269.60 million for Mumbai City and 2714.10 million to 6394.74 million for Delhi City, from 1995 to 2015, and the total amount accounting about 1.01% of India's gross domestic product (GDP). A crucial presumption is that in 2030, PM 10 levels would have to decline by 44% (Mumbai) and 67% (Delhi) absolutely to maintain the same health outcomes in year 2015 levels. The results will help policy makers from pollution control board for further cost-benefit analyses of air pollution management programs in Mumbai and Delhi.

First the SO{sub 2} abatement patterns of individual plants are presented, followed by the way the costs were distributed in the electricity sector. Finally the costs for individual measures and plants are elaborated. In chapter 5 the freedom to choose between alternatives to meet the SO{sub 2} demands is discussed. Although there was a covenant with SO{sub 2} and Nox implemented in the Netherlands with targets on the aggregate level of the sector, the actual freedom to choose, the allocative efficiency was seriously limited by existing regulation. In chapter 6 an assessment of administrative costs is given. Finally in chapter 7 some summarizing conclusions are drawn.

    In the developing electricity market, many questions on electricity pricing and the risk modelling of forward contracts require the evaluation of the expected value and probability distribution of the short-run marginal cost of power generation at any given time. A concise forecasting method is provided, which is consistent with the definitions of marginal costs and the techniques of probabilistic production costing. The method embodies clear physical concepts, so that it can be easily understood theoretically and computationally realised. A numerical example has been used to test the proposed method. (author)

    1980-01-01

    The discipline is economics and the phenomenon is the power system. The purpose of this system is to produce, transmit and consume electricity in such a way that the sum of consumers and suppliers surplus in maximized. This is accomplished by the means of marginal cost pricing. The concepts of the power system and the relations prevailing between and among them are picked out, defined and analyzed in the frames of economic theory and operations research. Methods are developed aiming at efficient prices so that the short run function of the power system is managed in such a way that the sum of conumers and suppliers surplus is maximized within the framwork of this system, i.e. value of service of the power system is maximized. The task of developing such methods is accomplished subject to mixed production resources, transmission losses, periodic demand and also when there is lack of information concerning future and cost conditions. The main results are methods which take to account the conditions stated above. Methods not only allowing for traditional cost minimizing but also for maximation of value of service including a process of reaching optimum by gradual adaption when demand and cost curves are not known in advance.

  13. Adjusting estimative prediction limits

    OpenAIRE

    Masao Ueki; Kaoru Fueda

    2007-01-01

    This note presents a direct adjustment of the estimative prediction limit to reduce the coverage error from a target value to third-order accuracy. The adjustment is asymptotically equivalent to those of Barndorff-Nielsen & Cox (1994, 1996) and Vidoni (1998). It has a simpler form with a plug-in estimator of the coverage probability of the estimative limit at the target value. Copyright 2007, Oxford University Press.

    We investigate the existence of markups and their cyclical behaviour. Markup is not directly observed. Instead, it is given as a price-cost relation that is estimated from a dynamic model of the firm. The model incorporates potential costly employment adjustments and takes into consideration that firms may be financially constrained. When considering size of the future labour stock, financially constrained firms may behave as if they have a higher discount factor, which may affect the realise...

  16. Organizational coordination and costly communication with boundedly rational agents

    DEFF Research Database (Denmark)

    Dietrichson, Jens; Jochem, Torsten

    How does costly communication affect organizational coordination? This paper develops a model of costly communication based on the weakest-link game and boundedly rational agents. Solving for the stochastically stable states, we find that communication increases the possibilities for efficient...... coordination compared to a setting where agents cannot communicate. But as agents face a trade-off between lowering the strategic uncertainty for the group and the costs of communication, the least efficient state is still the unique stochastically stable one for many parameter values. Simulations show...... that this is not just a long run phenomena, the stochastically stable state is the most frequent outcome also in the short run. Making communication mandatory induces efficient coordination, whereas letting a team leader handle communication increases efficiency when the leader expects others to follow and has enough...

  17. Cost-estimating for commercial digital printing

    Science.gov (United States)

    Keif, Malcolm G.

    2007-01-01

    The purpose of this study is to document current cost-estimating practices used in commercial digital printing. A research study was conducted to determine the use of cost-estimating in commercial digital printing companies. This study answers the questions: 1) What methods are currently being used to estimate digital printing? 2) What is the relationship between estimating and pricing digital printing? 3) To what extent, if at all, do digital printers use full-absorption, all-inclusive hourly rates for estimating? Three different digital printing models were identified: 1) Traditional print providers, who supplement their offset presswork with digital printing for short-run color and versioned commercial print; 2) "Low-touch" print providers, who leverage the power of the Internet to streamline business transactions with digital storefronts; 3) Marketing solutions providers, who see printing less as a discrete manufacturing process and more as a component of a complete marketing campaign. Each model approaches estimating differently. Understanding and predicting costs can be extremely beneficial. Establishing a reliable system to estimate those costs can be somewhat challenging though. Unquestionably, cost-estimating digital printing will increase in relevance in the years ahead, as margins tighten and cost knowledge becomes increasingly more critical.

  20. Speed of adjustment and market structure

    International Nuclear Information System (INIS)

    Lanza, A.

    1991-01-01

    This paper studies the relationship between changes in costs and prices in the gasoline market in the Federal Republic of Germany for the period 1980-90. We shall use an econometric model, and distinguish two stages in the transmission of cost changes to prices. The first is the adjustment of gasoline prices ex-refinery to changes in the price of crude oil, and the second is the adjustment of gasoline price (net of taxes) at the pump to ex-refinery prices. The study of price adjustments to cost changes involves the analysis of two inter-related but different phenomena. The first is the speed of adjustment, defined here as the mean of the length of the time periods required for the transmission of the full effect of an exogenous shock from the independent to the dependent variable of the econometric model used in the analysis. The second relates to possible asymmetries in the response of prices to increases and decreases in costs. Both phenomena are closely related to the structure of the market. The common assumption is that the first is negatively correlated to the degree of competition, and that the second is an indication of the prevailing market structure. The main findings of this paper are as follows: (a) at the refinery level there is only weak evidence of asymmetrical reaction; the average lag in case of crude price increases or decreases is about three months; (b) at the consumers' level, the speed of adjustment was lower when the ex-refinery price was declining than when it was rising; the adjustment lag was about 6.07 months when ex-refinery prices were declining and 5.37 months when they were rising.

    1998-07-01

    The authors describe a three dimensional frontier consisting of: spending, availability/reliability, and utilization/heat rate. To determine optimal behavior in a future deregulated market, one must also find the optimal adjustment path from present to long-run frontier operation, and the optimal strategic action/response as determined by game theory. One can also perform more limited optimizations along either the two dimensional spending/reliability or spending/utilization frontiers. Although the authors mainly discuss optimizing existing domestic plants, frontier analysis could easily be applied to an electric producer's plants or acquisition targets internationally. Efficient operation saves money even in countries where electric markets are still regulated and can also confer indirect environmental benefits. AER is also applying these frontier analysis and game theory techniques to environmental decision-making, specifically to environmental retrofit decisions.

  5. The importance of fixed costs in animal health systems.

    Science.gov (United States)

    Tisdell, C A; Adamson, D

    2017-04-01

    In this paper, the authors detail the structure and optimal management of health systems as influenced by the presence and level of fixed costs. Unlike variable costs, fixed costs cannot be altered, and are thus independent of the level of veterinary activity in the short run. Their importance is illustrated by using both single-period and multi-period models. It is shown that multi-stage veterinary decision-making can often be envisaged as a sequence of fixed-cost problems. In general, it becomes clear that, the higher the fixed costs, the greater the net benefit of veterinary activity must be, if such activity is to be economic. The authors also assess the extent to which it pays to reduce fixed costs and to try to compensate for this by increasing variable costs. Fixed costs have major implications for the industrial structure of the animal health products industry and for the structure of the private veterinary services industry. In the former, they favour market concentration and specialisation in the supply of products. In the latter, they foster increased specialisation. While cooperation by individual farmers may help to reduce their individual fixed costs, the organisational difficulties and costs involved in achieving this cooperation can be formidable. In such cases, the only solution is government provision of veterinary services. Moreover, international cooperation may be called for. Fixed costs also influence the nature of the provision of veterinary education.

  6. Adjustment of interbank lending in pre- and post-regulation periods: Empirical analysis of Vietnamese commercial banks

    2017-10-01

    Full Text Available This article aims to analyze the interbank lending adjustment during the period when Vietnamese commercial banks are compliant with some parts of the Basel regulation framework. A pilot regulation period has started in 2011 and full application will be effective by the end of 2018. Partial adjustment models and variance decomposition are used for the analyses. In the analysis of the quarterly released financial statements of Vietnamese commercial banks in the period from 2008/Q1 to 2015/Q4, the empirical evidence showed that throughout the period, lending to non-bank and high liquidity assets contributed to the adjustment in both long run and short run with a negative association. In addition, the loan loss allowance contributed to the adjustment in the post-regulation period only with a positive association. These highly contributing factors also show a potential shock after the adjustment of the interbank lending. The results imply there is a need for interbank lending portfolio report and an efficient control over the IRB of Vietnamese commercial banks.

    Full Text Available Paulina Zelviene, Evaldas Kazlauskas Department of Clinical and Organizational Psychology, Vilnius University, Vilnius, Lithuania Abstract: Adjustment disorder (AjD is among the most often diagnosed mental disorders in clinical practice. This paper reviews current status of AjD research and discusses scientific and clinical issues associated with AjD. AjD has been included in diagnostic classifications for over 50 years. Still, the diagnostic criteria for AjD remain vague and cause difficulties to mental health professionals. Controversies in definition resulted in the lack of reliable and valid measures of AjD. Epidemiological data on prevalence of AjD is scarce and not reliable because prevalence data are biased by the diagnostic algorithm, which is usually developed for each study, as no established diagnostic standards for AjD are available. Considerable changes in the field of AjD could follow after the release of the 11th edition of International Classification of Diseases (ICD-11. A new AjD symptom profile was introduced in ICD-11 with 2 main symptoms as follows: 1 preoccupation and 2 failure to adapt. However, differences between the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition and ICD-11 AjD diagnostic criteria could result in diverse research findings in the future. The best treatment approach for AjD remains unclear, and further treatment studies are needed to provide AjD treatment guidelines to clinicians.

    Jacobs, Ken; Karpf, Ron

    2011-03-01

    A number of Pulfrich 3-D movies and TV shows have been produced, but the standard implementation has inherent drawbacks. The movie and TV industries have correctly concluded that the standard Pulfrich 3-D implementation is not a useful 3-D technique. Continuously Adjustable Pulfrich Spectacles (CAPS) is a new implementation of the Pulfrich effect that allows any scene containing movement in a standard 2-D movie, which are most scenes, to be optionally viewed in 3-D using inexpensive viewing specs. Recent scientific results in the fields of human perception, optoelectronics, video compression and video format conversion are translated into a new implementation of Pulfrich 3- D. CAPS uses these results to continuously adjust to the movie so that the viewing spectacles always conform to the optical density that optimizes the Pulfrich stereoscopic illusion. CAPS instantly provides 3-D immersion to any moving scene in any 2-D movie. Without the glasses, the movie will appear as a normal 2-D image. CAPS work on any viewing device, and with any distribution medium. CAPS is appropriate for viewing Internet streamed movies in 3-D.

  12. Adjustment Criterion and Algorithm in Adjustment Model with Uncertain

    Directory of Open Access Journals (Sweden)

    SONG Yingchun

    2015-02-01

    Full Text Available Uncertainty often exists in the process of obtaining measurement data, which affects the reliability of parameter estimation. This paper establishes a new adjustment model in which uncertainty is incorporated into the function model as a parameter. A new adjustment criterion and its iterative algorithm are given based on uncertainty propagation law in the residual error, in which the maximum possible uncertainty is minimized. This paper also analyzes, with examples, the different adjustment criteria and features of optimal solutions about the least-squares adjustment, the uncertainty adjustment and total least-squares adjustment. Existing error theory is extended with new observational data processing method about uncertainty.

    The Money's Worth Ratio (MWR) measures an annuity's actuarial fairness. It is calculated as the discounted present value of expected future payments divided by its cost. We argue that from the perspective of annuitants, this measure may overestimate the value-for-money obtained, since it does not adjust for liquidity or risk factors. Measuring these factors is challenging, requiring detailed knowledge of assets, liabilities, and of the stochastic processes followed by them. Using a multi-fact...

  20. Health care costs: saving in the private sector.

    Science.gov (United States)

    Robeson, F E

    1979-01-01

    Robeson offers a number of options to employers to help reduce the impact of increasing health care costs. He points out that large organizations which employ hundreds of people have considerable market power which can be exerted to contain costs. It is suggested that the risk management departments assume the responsibility for managing the effort to reduce the costs of medical care and of the health insurance programs of these organizations since that staff is experienced at evaluating premiums and negotiating with third-party payors. The article examines a number of short-run strategies for firms to pursue to contain health care costs: (1) use alternative delivery systems such as health maintenance organizations (HMOs) which have cost-cutting potential but require marketing efforts to persuade employees of their desirability; (2) contracts with third-party payors which require a second opinion (peer review), a practice which saved one labor union over $2 million from 1972 to 1976; (3) implementation of insurance coverage for less expensive outpatient care; and (4) the use of claims review. These strategies are compared in terms of four criteria: supply of demand for health services; management effort; cost; and time necessary for realized savings. Robeson concludes that development of a management plan for containing health care costs requires an extensive analysis of alternatives, organizational objectives, existing policies, and resources, and offers a table summarizing the cost-containment strategies that a firm should consider.

    This article describes a system of diagnostic categories that Medicaid programs can use for adjusting capitation payments to health plans that enroll people with disability. Medicaid claims from Colorado, Michigan, Missouri, New York, and Ohio are analyzed to demonstrate that the greater predictability of costs among people with disabilities makes risk adjustment more feasible than for a general population and more critical to creating health systems for people with disability. The application of our diagnostic categories to State claims data is described, including estimated effects on subsequent-year costs of various diagnoses.

    Postoperative adjuvant chemotherapy with capecitabine and oxaliplatin was first recommended for resectable gastric cancer patients in the 2011 Chinese National Comprehensive Cancer Network Clinical Practice Guidelines in Oncology: Gastric Cancer, but the economic influence of this therapy in China is unknown. The aim of the present study was to determine the cost-effectiveness of adjuvant chemotherapy with capecitabine and oxaliplatin after a gastrectomy with extended (D2) lymph-node dissection, compared with a D2 gastrectomy alone, for patients with stage II-IIIB gastric cancer. On the basis of data from the CLASSIC trial, a Markov model was created to determine economic and clinical data for patients in the chemotherapy and surgery group (CSG) and the surgery-only group (SOG). The costs, presented in 2010 US dollars and estimated from the perspective of the Chinese health-care system, were obtained from the published literature and the local health system. The utilities were based on published literature. Costs, life years (LYs), quality-adjusted life years (QALYs), and incremental cost-effectiveness ratios (ICER) were estimated. A lifetime horizon and a 3 % annual discount rate were used. One-way and probabilistic sensitivity analyses were performed. For the base case, the CSG compared with SOG would increase LYs and QALYs in a 3-, 5-, 10- or 30-year time horizon (except the QALYs at 3 or 5 years). In the short run (such as in 3 or 5 years), the medical costs would increase owing to adjuvant chemotherapy of capecitabine plus oxaliplatin after D2 gastrectomy, but in the long run the costs would decline. The ICERs suggested that the SOG was dominant at 3 or 5 years and the CSG was dominant at 10 or 30 years. The one-way sensitivity analysis showed that the utility of disease-free survival for 1-10 years for the SOG and the cost of oxaliplatin were the most influential parameters. The probabilistic sensitivity analysis predicted a 98.6 % likelihood that the ICER

    International Nuclear Information System (INIS)

    Trnkova, L.; Rulik, P.

    2008-01-01

    Low-level background shielding of HPGe detectors is used mainly for environmental samples with very low content of radionuclides. National Radiation Protection Institute (SURO) in Prague is equipped with 14 HPGe detectors with relative efficiency up to 150%. The detectors are placed in a room built from materials with low content of natural radionuclides and equipped with a double isolation of the floor against radon. Detectors themselves are placed in lead or steel shielding. Steel shielding with one of these detectors with relative efficiency of 100% was chosen to be rebuilt to achieve lower minimum detectable activity (MDA). Additional lead and copper shielding was built up inside the original steel shielding to reduce the volume of the inner space and filled with nitrogen by means of evaporating liquid nitrogen. The additional lead and copper shielding, consequent reduction of the inner volume and supply of evaporated nitrogen, caused a decrease of the background count and accordingly MDA values as well. The effect of nitrogen evaporation on the net areas of peaks belonging to radon daughters is significant. The enhanced shielding adjustment has the biggest influence in low energy range, what can be seen in collected data. MDA values in energy range from 30 keV to 400 keV decreased to 0.65-0.85 of original value, in energy range from 400 keV to 2 MeV they fell to 0.70-0.97 of original value. (authors)

    2010-01-01

    Major guidelines regarding the application of cost-effectiveness analysis (CEA) have recommended the common and widespread use of the "societal perspective" for purposes of consistency and comparability. The objective of this Task Force subgroup report (one of six reports from the International Society for Pharmacoeconomics and Outcomes Research [ISPOR] Task Force on Good Research Practices-Use of Drug Costs for Cost Effectiveness Analysis [Drug Cost Task Force (DCTF)]) was to review the definition of this perspective, assess its specific application in measuring drug costs, identify any limitations in theory or practice, and make recommendations regarding potential improvements. Key articles, books, and reports in the methodological literature were reviewed, summarized, and integrated into a draft review and report. This draft report was posted for review and comment by ISPOR membership. Numerous comments and suggestions were received, and the report was revised in response to them. The societal perspective can be defined by three conditions: 1) the inclusion of time costs, 2) the use of opportunity costs, and 3) the use of community preferences. In practice, very few, if any, published CEAs have met all of these conditions, though many claim to have taken a societal perspective. Branded drug costs have typically used actual acquisition cost rather than the much lower social opportunity costs that would reflect only short-run manufacturing and distribution costs. This practice is understandable, pragmatic, and useful to current decision-makers. Nevertheless, this use of CEA focuses on static rather than dynamic efficacy and overlooks the related incentives for innovation. Our key recommendation is that current CEA practice acknowledge and embrace this limitation by adopting a new standard for the reference case as one of a "limited societal" or "health systems" perspective, using acquisition drug prices while including indirect costs and community preferences.

    Conventional hard automation, such as a linkage-based or a cam-driven system, provides high speed capability and repeatability but not the flexibility required in many industrial applications. The conventional mechanisms, that are typically single-degree-of-freedom systems, are being increasingly replaced by multi-degree-of-freedom multi-actuators driven by logic controllers. Although this new trend in sophistication provides greatly enhanced flexibility, there are many instances where the flexibility needs are exaggerated and the associated complexity is unnecessary. Traditional mechanism-based hard automation, on the other hand, neither can fulfill multi-task requirements nor are cost-effective mainly due to lack of methods and tools to design-in flexibility. This dissertation attempts to bridge this technological gap by developing Adjustable Robotic Mechanisms (ARM's) or 'programmable mechanisms' as a middle ground between high speed hard automation and expensive serial jointed-arm robots. This research introduces the concept of adjustable robotic mechanisms towards cost-effective manufacturing automation. A generalized analytical synthesis technique has been developed to support the computational design of ARM's that lays the theoretical foundation for synthesis of adjustable mechanisms. The synthesis method developed in this dissertation, called generalized adjustable dyad and triad synthesis, advances the well-known Burmester theory in kinematics to a new level. While this method provides planar solutions, a novel patented scheme is utilized for converting prescribed three-dimensional motion specifications into sets of planar projections. This provides an analytical and a computational tool for designing adjustable mechanisms that satisfy multiple sets of three-dimensional motion specifications. Several design issues were addressed, including adjustable parameter identification, branching defect, and mechanical errors. An efficient mathematical scheme for

  8. COST MEASUREMENT AND COST MANAGEMENT IN TARGET COSTING

    Full Text Available Firms are coping with a competitive scenario characterized by quick changes produced by internationalization, concentration, restructuring, technological innovation processes and financial market crisis. On the one hand market enlargement have increased the number and the segmentation of customers and have raised the number of competitors, on the other hand technological innovation has reduced product life cycle. So firms have to adjust their management models to this scenario, pursuing customer satisfaction and respecting cost constraints. In a context where price is a variable fixed by the market, firms have to switch from the cost measurement logic to the cost management one, adopting target costing methodology. The target costing process is a price driven, customer oriented profit planning and cost management system. It works, in a cross functional way, from the design stage throughout all the product life cycle and it involves the entire value chain. The process implementation needs a costing methodology consistent with the cost management logic. The aim of the paper is to focus on Activity Based Costing (ABC application to target costing process. So: -it analyzes target costing logic and phases, basing on a literary review, in order to highlight the costing needs related to this process; -it shows, through a numerical example, how to structure a flexible ABC model – characterized by the separation between variable, fixed in the short and fixed costs - that effectively supports target costing process in the cost measurement phase (drifting cost determination and in the target cost alignment; -it points out the effectiveness of the Activity Based Costing as a model of cost measurement applicable to the supplier choice and as a support for supply cost management which have an important role in target costing process. The activity based information allows a firm to optimize the supplier choice by following the method of minimizing the

    Using 1991-92 data for a 5-percent Medicare sample, we develop, estimate, and evaluate risk-adjustment models that utilize diagnostic information from both inpatient and ambulatory claims to adjust payments for aged and disabled Medicare enrollees. Hierarchical coexisting conditions (HCC) models achieve greater explanatory power than diagnostic cost group (DCG) models by taking account of multiple coexisting medical conditions. Prospective models predict average costs of individuals with chronic conditions nearly as well as concurrent models. All models predict medical costs far more accurately than the current health maintenance organization (HMO) payment formula. PMID:10172666

  10. How do high cost-sharing policies for physician care affect total care costs among people with chronic disease?

    Science.gov (United States)

    Xin, Haichang; Harman, Jeffrey S; Yang, Zhou

    2014-01-01

    This study examines whether high cost-sharing in physician care is associated with a differential impact on total care costs by health status. Total care includes physician care, emergency room (ER) visits and inpatient care. Since high cost-sharing policies can reduce needed care as well as unneeded care use, it raises the concern whether these policies are a good strategy for controlling costs among chronically ill patients. This study used the 2007 Medical Expenditure Panel Survey data with a cross-sectional study design. Difference in difference (DID), instrumental variable technique, two-part model, and bootstrap technique were employed to analyze cost data. Chronically ill individuals' probability of reducing any overall care costs was significantly less than healthier individuals (beta = 2.18, p = 0.04), while the integrated DID estimator from split results indicated that going from low cost-sharing to high cost-sharing significantly reduced costs by $12,853.23 more for sick people than for healthy people (95% CI: -$17,582.86, -$8,123.60). This greater cost reduction in total care among sick people likely resulted from greater cost reduction in physician care, and may have come at the expense of jeopardizing health outcomes by depriving patients of needed care. Thus, these policies would be inappropriate in the short run, and unlikely in the long run to control health plans costs among chronically ill individuals. A generous benefit design with low cost-sharing policies in physician care or primary care is recommended for both health plans and chronically ill individuals, to save costs and protect these enrollees' health status.

    2013-01-01

    Full Text Available The aim of this paper is to establish a general methodology for calculating the costs incurred by employee turnover. This paper deals with identification of costs incurred by the departure of an employee, and does not deal with the cost of recruitment of a new employee. Economic calculations are adjusted to the tax policy in the Czech Republic. The costs of employee turnover (according to Bliss, 2012 include the costs of substitution of the unoccupied position, costs of conducting the exit interview and termination of the contract. The cost of an executive’s time to understand the causes of leaving and costs of the leaving employee’s training were also determined. Important factors in the costs of employee turnover also include the loss of knowledge and possibly also a loss of customers. Costs of lost employee and department productiveness represent an important part of the costs of employee turnover, as well. For all of these costs there have been proposed general calculations formulas.

  20. Costs of groundwater contamination

    International Nuclear Information System (INIS)

    O'Neil, W.B.; Raucher, R.S.

    1990-01-01

    Two factors determine the cost of groundwater contamination: (1) the ways in which water was being used or was expected to be used in the future and (2) the physical characteristics of the setting that constrain the responses available to regain lost uses or to prevent related damages to human health and the environment. Most contamination incidents can be managed at a low enough cost that uses will not be foreclosed. It is important to take into account the following when considering costs: (1) natural cleansing through recharge and dilution can take many years; (2) it is difficult and costly to identify the exact area and expected path of a contamination plume; and (3) treatment or replacement of contaminated water often may represent the cost-effective strategy for managing the event. The costs of contamination include adverse health effects, containment and remediation, treatment and replacement costs. In comparing the costs and benefits of prevention programs with those of remediation, replacement or treatment, it is essential to adjust the cost/benefit numbers by the probability of their actual occurrence. Better forecasts of water demand are needed to predict more accurately the scarcity of new supply and the associated cost of replacement. This research should include estimates of the price elasticity of water demand and the possible effect on demand of more rational cost-based pricing structures. Research and development of techniques for in situ remediation should be encouraged

    This article reviews the research literature on links between parental divorce and children's short-term and long-term adjustment. First, I consider evidence regarding how divorce relates to children's externalizing behaviors, internalizing problems, academic achievement, and social relationships. Second, I examine timing of the divorce, demographic characteristics, children's adjustment prior to the divorce, and stigmatization as moderators of the links between divorce and children's adjustment. Third, I examine income, interparental conflict, parenting, and parents well-being as mediators of relations between divorce and children's adjustment. Fourth, I note the caveats and limitations of the research literature. Finally, I consider notable policies related to grounds for divorce, child support, and child custody in light of how they might affect children s adjustment to their parents divorce. © 2009 Association for Psychological Science.

    While drought is not uncommon in Zambia, the country is now facing the worst drought in history. The monetary and social costs will be enormous. Although it is too early to measure the economic and social costs of the drought on Zambia, it is obvious that the impact is catastrophic on a country whose economy is under pressure. The drought will affect the structural adjustment programme (SAP) unveiled by the new government which has embraced the market economy. The country has imported, and will continue to import, large quantities of maize and other foodstuffs, a situation likely to strain the balance of payments. Earlier targets with regard to export earnings, reductions in the budget deficit, and GDP growth as contained in the Policy Framework Paper (PFP) are no longer attainable due to the effects of the drought.

Refractive errors are an avoidable cause of visual impairment that are easily correctable. Provision of spectacles is a cost-effective measure. Unfortunately, this simple solution becomes a public health challenge in low- and middle-income countries because of the paucity of human resources for refraction and optical services, lack of access to refraction services in rural areas, and the cost of spectacles. Low-cost approaches to provide affordable glasses in developing countries are critical. A number of approaches has been tried to surmount the challenge, including ready-made spectacles, the use of focometers and self-adjustable glasses, among other modalities. Recently, self-adjustable spectacles have been validated in studies in both children and adults in developed and developing countries. A high degree of agreement between self-adjustable spectacles and cycloplegic subjective refraction has been reported. Self-refraction has also been found to be less prone to accommodative inaccuracy compared with non-cycloplegic autorefraction. The benefits of self-adjusted spectacles include: the potential for correction of both distance and near vision, applicability for all ages, the empowerment of lay workers, the increased participation of clients, augmented awareness of the mechanism of refraction, reduced costs of optical and refraction units in low-resource settings, and a relative reduction in costs for refraction services. Concerns requiring attention include a need for the improved cosmetic appearance of the currently available self-adjustable spectacles, an increased range of correction (currently

    1992-01-01

    An Adjustable Phase Undulator (APU) was installed and tested on the beamline 5 of the SPEAR storage ring. The APU has the same magnetic structure as a conventional adjustable gap undulator (AGU), but its magnetic field is varied by changing the longitudinal position between the rows of magnets, while keeping the gap between them fixed. The tests described here show that this undulator performs according to theoretical predictions and numerical models. The main reason to consider a phase adjustable design is the substantial reduction in size, complexity, and cost over comparable conventional designs. (author) 4 refs.; 3 figs

    2009-08-15

    The main objective of this study has been to review the future cost to decommission and dismantling the industrial area at the site of the old uranium mine at Ranstad in Sweden. Analyses of some detailed comparative empirical information have been used in the context of preliminary 'bench-marking' studies. The estimated costs for decommissioning of the old uranium mine in Ranstad have been compared with actual costs from other relevant decommissioning projects. In this way it has been possible to give a preliminary qualitative statement about the accuracy of the Ranstad cost estimate. The study gives the following lessons learned: 1. The available information suggests that the overall estimated cost may be reasonable, but there are still some points of weakness that need to be elaborated more in detail before a full statement about the adequacy of the forecast cost will be possible. 2. Especially the costs associated with declassification activities warrant further analysis in order to determine there level of accuracy. 3. There exists the possibility that the estimate might be low concerning decontamination, dismantling and planning and institutional work. 4. Further work and analysis is needed in order to develop a more transparent cost estimate in which the stakeholders can have the highest confidence. 5. A new bidding procedure for the conventional demolition may result in lower estimated costs. Hence, it would be beneficial to obtain an updated estimate based on at least more than one quotation. 6. The method of addressing uncertainty and risk should be more connected to the logistics of specific decommissioning activities, in order to be more transparent and clearer in details. There is a need for further study to develop a better estimate. In the short run follow-up work needs to be undertaken to provide a better understanding of what are the major contributors to risk and cost drivers in the planned decommissioning process at the Ranstad

    The rise of electronic games has driven both concerns and hopes regarding their potential to influence young people. Existing research identifies a series of isolated positive and negative effects, yet no research to date has examined the balance of these potential effects in a representative sample of children and adolescents. The objective of this study was to explore how time spent playing electronic games accounts for significant variation in positive and negative psychosocial adjustment using a representative cohort of children aged 10 to 15 years. A large sample of children and adolescents aged 10 to 15 years completed assessments of psychosocial adjustment and reported typical daily hours spent playing electronic games. Relations between different levels of engagement and indicators of positive and negative psychosocial adjustment were examined, controlling for participant age and gender and weighted for population representativeness. Low levels (3 hours daily) of game engagement was linked to key indicators of psychosocial adjustment. Low engagement was associated with higher life satisfaction and prosocial behavior and lower externalizing and internalizing problems, whereas the opposite was found for high levels of play. No effects were observed for moderate play levels when compared with non-players. The links between different levels of electronic game engagement and psychosocial adjustment were small (Games consistently but not robustly associated with children's adjustment in both positive and negative ways, findings that inform policy-making as well as future avenues for research in the area.

    Science.gov (United States)

    Lamers, L M

    Adequate risk adjustment is critical to the success of market-oriented health care reforms in many countries. Currently used risk adjusters based on demographic and diagnostic cost groups (DCGs) do not reflect expected costs accurately. This study examines the simultaneous predictive accuracy of inpatient and outpatient morbidity measures and prior costs. DCGs, pharmacy cost groups (PCGs), and prior year's costs improve the predictive accuracy of the demographic model substantially. DCGs and PCGs seem complementary in their ability to predict future costs. However, this study shows that the combination of DCGs and PCGs still leaves room for cream skimming.

    Klumpar, I.V.; Soltz, K.M.

    1985-01-01

    The nuclear industry has higher costs for personnel, equipment, construction, and engineering than conventional industry, which means that cost estimation procedures may need adjustment. The authors account for the special technical and labor requirements of the nuclear industry in making adjustments to equipment and installation cost estimations. Using illustrative examples, they show that conventional methods of preliminary cost estimation are flexible enough for application to emerging industries if their cost structure is similar to that of the process industries. If not, modifications can provide enough engineering and cost data for a statistical analysis. 9 references, 14 figures, 4 tables

    Caughey, Aaron B; Burchfield, David J

    2014-02-01

    With increasing concerns regarding rapidly expanding healthcare costs, cost-effectiveness analysis allows assessment of whether marginal gains from new technology are worth the increased costs. Particular methodologic issues related to cost and cost-effectiveness analysis in the area of neonatal and periviable care include how costs are estimated, such as the use of charges and whether long-term costs are included; the challenges of measuring utilities; and whether to use a maternal, neonatal, or dual perspective in such analyses. A number of studies over the past three decades have examined the costs and the cost-effectiveness of neonatal and periviable care. Broadly, while neonatal care is costly, it is also cost effective as it produces both life-years and quality-adjusted life-years (QALYs). However, as the gestational age of the neonate decreases, the costs increase and the cost-effectiveness threshold is harder to achieve. In the periviable range of gestational age (22-24 weeks of gestation), whether the care is cost effective is questionable and is dependent on the perspective. Understanding the methodology and salient issues of cost-effectiveness analysis is critical for researchers, editors, and clinicians to accurately interpret results of the growing body of cost-effectiveness studies related to the care of periviable pregnancies and neonates.

  18. A probabilistic production costing analysis of SO2 emissions reduction strategies for Ohio: emissions, costs and employment tradeoffs

    International Nuclear Information System (INIS)

    Heslin, J.S.; Hobbs, B.F.

    1991-01-01

    A new approach for state- and utility-level analysis of the cost and regional economic impacts of strategies for reducing utility SO 2 emissions is summarized and applied to Ohio. The methodology is based upon probabilistic production costing and economic input-output analysis. It is an improvement over previous approaches because it: (1) accurately models random outages of generating units, 'must-run' constraints on unit output, and the distribution of power demands; and (2) runs quickly on a microcomputer and yet considers the entire range of potential control strategies from a systems perspective. The input-output analysis considers not only the economic effects of utility fuel use and capital investment, but also those of increased electric rates. Two distinct strategies are found to be most attractive for Ohio. The first, more flexible one, consists of emissions dispatching (ED) alone to meet short run emissions reduction targets. A 75 percent reduction can then be achieved by the turn of the century by combining ED and fuel switching (FS) with flue gas desulfurization, limestone injection multistage burners, and physical coal cleaning at selected plants. The second is a scrubber-based strategy which includes ED. By the year 2000, energy conservation becomes a cost effective component of these strategies. In order to minimize compliance costs, acid rain legislation which facilitates emission trading and places regional tonnage limits on emissions is desirable

    Two studies investigated relationships between traditional indicators of acculturation, cultural distance, acculturation strategies, and basic dimensions of personality as they pertain to psychological adjustment among Hispanic students. Although personality characteristics have been shown to be important determinants of psychological well-being, acculturation research has put less emphasis on the role of personality in the well-being of immigrants. Hierarchical regression analysis showed that basic dimensions of personality such as extraversion and neuroticism were strongly related to psychological adjustment. Acculturation strategies did not mediate the effect of personality variables, but cultural resistance made a small, independent contribution to the explanation of some aspects of negative psychological adjustment. The implications of the results were discussed.

    Full Text Available To deal with massive data in photogrammetry, we introduce the GPU parallel computing technology. The preconditioned conjugate gradient and inexact Newton method are also applied to decrease the iteration times while solving the normal equation. A brand new workflow of bundle adjustment is developed to utilize GPU parallel computing technology. Our method can avoid the storage and inversion of the big normal matrix, and compute the normal matrix in real time. The proposed method can not only largely decrease the memory requirement of normal matrix, but also largely improve the efficiency of bundle adjustment. It also achieves the same accuracy as the conventional method.

    Science.gov (United States)

    Allaire, F R; Gibson, J P

    1992-05-01

    Cow herd life adjusted for lactational milk production was investigated as a genetic trait in the breeding objective. Under a simple model, the relative economic weight of milk to adjusted herd life on a per genetic standard deviation basis was equal to CVY/dCVL where CVY and CVL are the genetic coefficients of variation of milk production and adjusted herd life, respectively, and d is the depreciation per year per cow divided by the total fixed costs per year per cow. The relative economic value of milk to adjusted herd life at the prices and parameters for North America was about 3.2. An increase of 100-kg milk was equivalent to 2.2 mo of adjusted herd life. Three to 7% lower economic gain is expected when only improved milk production is sought compared with a breeding objective that included both production and adjusted herd life for relative value changed +/- 20%. A favorable economic gain to cost ratio probably exists for herd life used as a genetic trait to supplement milk in the breeding objective. Cow survival records are inexpensive, and herd life evaluations from such records may not extend the generation interval when such an evaluation is used in bull sire selection.

    1981-01-01

    The introduction of kinematic adjustments by adding the displaced blocks is studied theoretically and in test seismograms. The advantage to this method resulting from the weight variation in the trace is demonstrated together with its kinematic drawback. A variation on the displaced block addition method that does not involve realignment of the travel time curves and that has improved amplitude characteristics is proposed.

  5. Costs and benefits of employment transportation for low-wage workers: an assessment of job access public transportation services.

    2013-04-01

    This paper focuses on an evaluation of public transportation-based employment transportation (ET) services to transport low-wage workers to jobs in the US. We make an attempt to capture a more comprehensive range of intended and unintended outcomes of ET services than those traditionally considered in the case of public transportation services. Using primary data from 23 locations across the country, we present a framework to evaluate how transportation improvements, in interaction with labor markets, can affect users' short-run economic welfare, users' long-run human capital accumulation and non-users' short-run economic welfare. These services were partially funded by a specialized program - the Job Access and Reverse Commute (JARC) program - which was consolidated into larger transit funding programs by recent legislation. In the sites examined, we found that low wage users benefited from self-reported increased access to jobs, improvements in earnings potential, as well as from savings in transport cost and time. Simulations show the potential of users to accrue long-term worklife benefits. At the same time, users may have accrued changes in leisure time as a result of transitioning from unemployment to employment, and generated a range of societal impacts on three classes of non-users: the general tax-paying public, the general commuting public in the service operating area and other low-wage workers in local labor markets.

    Dent, R.A.; Dicic, Z.

    1994-01-01

    This paper illustrates the integration of electrical and mechanical engineering requirements to produce a solution to past problems and future operating demands. The application of adjustable speed drives in the modifications of the circulating water system at Indian Point No. 3 Nuclear Power Plant provided increased operating flexibility, efficiency and avoided otherwise costly renovations to the plant electrical systems. Rectification of the original inadequate design of the circulating water system, in addition to maximizing plant efficiency consistent with environmental considerations, formed the basis for this modification. This entailed replacement of all six circulating water pumps and motors and physical modifications to the intake system. This paper details the methodology used in this engineering task. The new system was installed successfully and has been operating reliably and economically for the past eight years

  10. Transmission line capital costs

    International Nuclear Information System (INIS)

    Hughes, K.R.; Brown, D.R.

    1995-05-01

    The displacement or deferral of conventional AC transmission line installation is a key benefit associated with several technologies being developed with the support of the U.S. Department of Energy's Office of Energy Management (OEM). Previous benefits assessments conducted within OEM have been based on significantly different assumptions for the average cost per mile of AC transmission line. In response to this uncertainty, an investigation of transmission line capital cost data was initiated. The objective of this study was to develop a database for preparing preliminary estimates of transmission line costs. An extensive search of potential data sources identified databases maintained by the Bonneville Power Administration (BPA) and the Western Area Power Administration (WAPA) as superior sources of transmission line cost data. The BPA and WAPA data were adjusted to a common basis and combined together. The composite database covers voltage levels from 13.8 to 765 W, with cost estimates for a given voltage level varying depending on conductor size, tower material type, tower frame type, and number of circuits. Reported transmission line costs vary significantly, even for a given voltage level. This can usually be explained by variation in the design factors noted above and variation in environmental and land (right-of-way) costs, which are extremely site-specific. Cost estimates prepared from the composite database were compared to cost data collected by the Federal Energy Regulatory Commission (FERC) for investor-owned utilities from across the United States. The comparison was hampered because the only design specifications included with the FERC data were voltage level and line length. Working within this limitation, the FERC data were not found to differ significantly from the composite database. Therefore, the composite database was judged to be a reasonable proxy for estimating national average costs

  11. Approaches to estimating decommissioning costs

    International Nuclear Information System (INIS)

    Smith, R.I.

    1990-07-01

    The chronological development of methodology for estimating the cost of nuclear reactor power station decommissioning is traced from the mid-1970s through 1990. Three techniques for developing decommissioning cost estimates are described. The two viable techniques are compared by examining estimates developed for the same nuclear power station using both methods. The comparison shows that the differences between the estimates are due largely to differing assumptions regarding the size of the utility and operating contractor overhead staffs. It is concluded that the two methods provide bounding estimates on a range of manageable costs, and provide reasonable bases for the utility rate adjustments necessary to pay for future decommissioning costs. 6 refs

  12. Cost Behavior

    DEFF Research Database (Denmark)

    Hoffmann, Kira

    The objective of this dissertation is to investigate determinants and consequences of asymmetric cost behavior. Asymmetric cost behavior arises if the change in costs is different for increases in activity compared to equivalent decreases in activity. In this case, costs are termed “sticky......” if the change is less when activity falls than when activity rises, whereas costs are termed “anti-sticky” if the change is more when activity falls than when activity rises. Understanding such cost behavior is especially relevant for decision-makers and financial analysts that rely on accurate cost information...... to facilitate resource planning and earnings forecasting. As such, this dissertation relates to the topic of firm profitability and the interpretation of cost variability. The dissertation consists of three parts that are written in the form of separate academic papers. The following section briefly summarizes...

    The authors explored the factors influencing occupational adjustment related to workplace stress among 413 nurses at a Midwestern pediatric hospital. Among critical factors found in responses to their questionnaire and follow-up focus groups were differences in work adjustment and intergenerational conflicts. Both real and perceived workplace stress can manifest itself both fiscal and human costs by increasing turnover, absenteeism and worker's compensation claims as well as "faulty products and negative behaviors." Baby boomers (those born between 1946 and 1964) and Generation Xers (those born between 1965 and 1981) reported quite different issues and perceptions of occupational stress.

  14. Empirical evidence for resource-rational anchoring and adjustment.

    Science.gov (United States)

    Lieder, Falk; Griffiths, Thomas L; M Huys, Quentin J; Goodman, Noah D

    2018-04-01

    People's estimates of numerical quantities are systematically biased towards their initial guess. This anchoring bias is usually interpreted as sign of human irrationality, but it has recently been suggested that the anchoring bias instead results from people's rational use of their finite time and limited cognitive resources. If this were true, then adjustment should decrease with the relative cost of time. To test this hypothesis, we designed a new numerical estimation paradigm that controls people's knowledge and varies the cost of time and error independently while allowing people to invest as much or as little time and effort into refining their estimate as they wish. Two experiments confirmed the prediction that adjustment decreases with time cost but increases with error cost regardless of whether the anchor was self-generated or provided. These results support the hypothesis that people rationally adapt their number of adjustments to achieve a near-optimal speed-accuracy tradeoff. This suggests that the anchoring bias might be a signature of the rational use of finite time and limited cognitive resources rather than a sign of human irrationality.

  16. Short-run and long-run effects of unemployment on suicides: does welfare regime matter?

    Science.gov (United States)

    Gajewski, Pawel; Zhukovska, Kateryna

    2017-12-01

    Disentangling the immediate effects of an unemployment shock from the long-run relationship has a strong theoretical rationale. Different economic and psychological forces are at play in the first moment and after prolonged unemployment. This study suggests a diverse impact of short- and long-run unemployment on suicides in liberal and social-democratic countries. We take a macro-level perspective and simultaneously estimate the short- and long-run relationships between unemployment and suicide, along with the speed of convergence towards the long-run relationship after a shock, in a panel of 10 high-income countries. We also account for unemployment benefit spending, the share of the population aged 15-34, and the crisis effects. In the liberal group of countries, only a long-run impact of unemployment on suicides is found to be significant (P = 0.010). In social-democratic countries, suicides are associated with initial changes in unemployment (P = 0.028), but the positive link fades over time and becomes insignificant in the long run. Further, crisis effects are a much stronger determinant of suicides in social-democratic countries. Once the broad welfare regime is controlled for, changes in unemployment-related spending do not matter for preventing suicides. A generous welfare system seems efficient at preventing unemployment-related suicides in the long run, but societies in social-democratic countries might be less psychologically immune to sudden negative changes in their professional lives compared with people in liberal countries. Accounting for the different short- and long-run effects could thus improve our understanding of the unemployment-suicide link. © The Author 2017.

  17. Short run effects of bleaker prospects for oligopolistic producers of a non-renewable resource

    Energy Technology Data Exchange (ETDEWEB)

    Grimsrud, Kristine; Rosendahl, Knut Einar; Storroesten, Halvor Briseid; Tsygankova, Marina

    2013-01-15

    In a non-renewable resource market with imperfect competition, the resource owners' supply is governed both by current demand and by the resource rent. New information regarding future market conditions will typically affect the resource rent and hence current supply. Bleaker prospects will tend to accelerate extraction. We show, however, that for resource owners with substantial resource stocks, a more pessimistic outlook may in fact slow down early extraction. The explanation is that for players with extensive resource stocks, the resource rent is limited and supply is more driven by current market considerations. As players with less resources accelerate their supply, it may be optimal for the large resource owners to cut back on their supply. We illustrate this in the case of the European gas market, finding that the shale gas revolution may lead to an accelerated supply by most gas producers, but a postponement of Russian gas extraction.(Author)

  6. Radionuclide inventories for short run-time space nuclear reactor systems

    International Nuclear Information System (INIS)

    Coats, R.L.

    1993-01-01

    Space Nuclear Reactor Systems, especially those used for propulsion, often have expected operation run times much shorter than those for land-based nuclear power plants. This produces substantially different radionuclide inventories to be considered in the safety analyses of space nuclear systems. This presentation describes an analysis utilizing ORIGEN2 and DKPOWER to provide comparisons among representative land-based and space systems. These comparisons enable early, conceptual considerations of safety issues and features in the preliminary design phases of operational systems, test facilities, and operations by identifying differences between the requirements for space systems and the established practice for land-based power systems. Early indications are that separation distance is much more effective as a safety measure for space nuclear systems than for power reactors because greater decay of the radionuclide activity occurs during the time to transport the inventory a given distance. In addition, the inventories of long-lived actinides are very low for space reactor systems

    2015-01-01

    Using monthly data from 1994 to 2013 we study the long-run relation of the pre-tax retail prices of gasoline with crude price and the nominal exchange rate. We find a strongly significant long-run relation. We then use the nonlinear ARDL (NARDL) model to assess the asymmetries on both the short- and long-run elasticities, as well as the presence of hysteresis in the pricing behaviour. The estimation results confirm the presence of asymmetry in the long-run elasticities, with significant differences between the crude price and the exchange rate, as well as the presence of hysteresis in the relation between the retail price of gasoline and crude oil price. - Highlights: • The pass-through of crude oil prices and exchange rate into gasoline prices is examined. •We use an extended NARDL model to test for asymmetric reactions and hysteresis. • Asymmetric pricing behaviour features only in the long run. • The sign of the asymmetry differs between exchange rate and crude price changes. • The results are robust to the inclusion of several variables usually related to asymmetry

    2001-09-01

    Social-health care to oncological elderly patients implies interconnection among oncological hospital and sub-district services and acknowledgement of a sole access channel. The project requires the formation of an inter-administrative coordination group and of functional transmural units with evaluational and operative roles. Various care levels (protected hospital admission and discharge, continuity visits, evaluational-therapeutic integration during treatment, palliative cures) implicate specific criterion of eligibility and actions to rationalize organization, coordination and distribution of interventions. Efficiency and effectiveness depend on integration with the services that supply material and with the diagnostic and ambulatory ones. The mid-term prospectives of the integration regard computerization of diagnostic, therapeutic, care and rehabilitation courses of patients (Regional Computerized Register of Disability) and formation of polyfunctional centres that concern home, residential and hospital intervention. Powerful technological instruments and the new organizational forms now available should encourage the formation of a morally upright society.

Annual frequency data from 1990 to 2012 are utilized to develop an error correction framework that sheds light on short- and long-run electricity consumption behavior in Ciudad Juarez, a large Mexican metropolitan economy at the border with the United States. The results for this study reveal that electricity is an inelastic normal good in this market. Moreover, natural gas is found to be a weak complement to electricity. With regards to the customer base in this urban economy, population, employment, and income exercise positive and statistically significant impacts on the demand for electricity hook-ups.

  11. Electricity costs in liberalized market

    International Nuclear Information System (INIS)

    Barkans, J.; Junghans, G.

    2006-01-01

    In the liberalized electricity market the flexible demand determines the operation of power plants. Under market conditions the producers are forced to compete, and their power plants are normally loaded in order of increasing prices. The electricity costs consist of fixed and variable components, and the competition among producers simulates minimization of both the components. Considering the fixed costs (including maintenance, depreciation, capital costs and other permanent costs not depending on production) to be known, the total electricity costs in different operating conditions are based on the economic characteristics and the equipment load of a power plant. The paper describes the method for determination of electricity costs for condensing thermal power plants with permanent steam take-off for regeneration purposes and adjustable steam take-off for the needs of local heat energy consumers. The marginal costs for CHP plants are determined considering a number of different steam take-off from a turbine. At the electricity cost determination, auxiliary services also are taken into account. These can be reduced by adjusting the rotational speed of electric motors. The paper also shows how to determine the electricity costs for gas turbines, combined cycle gas turbines, and nuclear power plants. The position of hydro power plants among other PPs in the free market is also analysed. (authors)

  16. Perceived parenting and adolescents’ adjustment

    2018-05-01

    Full Text Available Abstract Adolescence is an important developmental period that is characterised by heightened problems of adjustment. The aim of this study is to analyse adolescents’ adjustment, and to explore the typologies and dimensions of parenting, and thus to determine the relationships between these factors. The sample comprised 1285 adolescent students aged 12 to 16 from the Basque Country (Spain. The students filled out the self-report of the Behavior Assessment System for Children (BASC and the Parental Acceptance-Rejection/Control Questionnaire, (PARQ/Control. Differences by age were found in the adolescents’ school maladjustment and parenting style perception. Moreover, perceptions of little parental warmth were related to higher levels of clinical and school maladjustment, and the lower the parental control, the greater the clinical maladjustment. Finally, the results obtained revealed that the interaction between the mothers’ and fathers’ parenting styles was significant only for clinical maladjustment; those students with neglectful mothers and authoritative fathers presented the highest level of clinical maladjustment, followed by other combinations of neglectful mothers. Furthermore, the students from neglectful and authoritarian families presented the highest levels of school maladjustment, without differences between neglectful and authoritarian or between indulgent and authoritative families.

  17. Adjusting case mix payment amounts for inaccurately reported comorbidity data.

    Sutherland, Jason M; Hamm, Jeremy; Hatcher, Jeff

    2010-03-01

    Case mix methods such as diagnosis related groups have become a basis of payment for inpatient hospitalizations in many countries. Specifying cost weight values for case mix system payment has important consequences; recent evidence suggests case mix cost weight inaccuracies influence the supply of some hospital-based services. To begin to address the question of case mix cost weight accuracy, this paper is motivated by the objective of improving the accuracy of cost weight values due to inaccurate or incomplete comorbidity data. The methods are suitable to case mix methods that incorporate disease severity or comorbidity adjustments. The methods are based on the availability of detailed clinical and cost information linked at the patient level and leverage recent results from clinical data audits. A Bayesian framework is used to synthesize clinical data audit information regarding misclassification probabilities into cost weight value calculations. The models are implemented through Markov chain Monte Carlo methods. An example used to demonstrate the methods finds that inaccurate comorbidity data affects cost weight values by biasing cost weight values (and payments) downward. The implications for hospital payments are discussed and the generalizability of the approach is explored.

  18. Struggles over patriarchal structural adjustment in Tanzania.

    Mbilinyi, M

    1993-10-01

    Within the space of 7 years (1986-93), structural adjustment policies have contributed to a reversal of the gains in economic development achieved in Tanzania in the 1960s and 1970s. Structural adjustment policies have helped large-scale producers and ordinary citizens but have led to a decline in social services which is reflected in drops in primary school enrollment and increases in medical costs. Government revenues are absorbed by foreign debt servicing. The reduction of support for social services has increased women's work; bolstered gender division of labor; and reduced women's access to education, formal employment, and health services. On the other hand, increased participation in market-oriented activities has increased women's mobility and exposure to modern ideas. This has led to changing gender relations which on the positive side can lead to shared decision-making but on the negative side may cause men to abdicate their familial responsibilities. Women suffer, however, from a lack of investment in ways to lighten their household responsibilities and have lost their ability to control food production because of the shift to cash crop production for export. The combination of hard work, low income, and stress has taken a toll on women's health, and both the maternal mortality rate and incidence of HIV infections among teenage girls has increased. In response to this situation, Tanzanian women have formed the Tanzania Gender Networking Programme (TGNP) which seeks to empower women and transform society through such activities as education and training, research, and lobbying and networking. Workshops sponsored by the TGNP have resulted in recommendations for adoption of a people-centered development strategy.

    Cross cultural training is widely believed to make a positive contribution to expatriate adjustment. In practice, however, it is very costly and sometimes ineffective for expatriates. Therefore, there is a growing importance placed on increasing the cost effectiveness or enhancing the efficacy of crosscultural training by functioning individual expatriate’s social capital and emotional intelligence as moderating variables towards expatriate’s adjustment and performance. To do so we blend idea...

  3. CASE STUDY ON RE-ADJUSTMENTS DEPENDING ON PRICE MODIFICATION

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available Inflationary moments, characterized by significant price rises, have proved that accountingsystems based on historical costs provide a distorted image of the reality: the elements ofthe balance sheet are under-valuated, and the stock-related expenses and amortization in theprofit and loss account are also under-valuated. Under these circumstances, the result isover-valuated, and its distribution leads to allotments from the company’s capital. In thispaper we draw up a case study with regards to the methods used for adjusting pricemodification, clearly outlining, through a comparative analysis, the main differencesbetween the accounting system based on historical cost and inflation accounting.

    This article reports differences across 23 countries on 2 processes of emotion regulation--reappraisal and suppression. Cultural dimensions were correlated with country means on both and the relationship between them. Cultures that emphasized the maintenance of social order--that is, those that were long-term oriented and valued embeddedness and hierarchy--tended to have higher scores on suppression, and reappraisal and suppression tended to be positively correlated. In contrast, cultures that minimized the maintenance of social order and valued individual Affective Autonomy and Egalitarianism tended to have lower scores on Suppression, and Reappraisal and Suppression tended to be negatively correlated. Moreover, country-level emotion regulation was significantly correlated with country-level indices of both positive and negative adjustment.

    Risk management is gaining importance in agriculture. In addition to traditional instruments, new risk management instruments are increasingly being proposed. These proposals include the rent adjustment clauses (RACs), which seem to be an unusual instrument at first sight. In contrast with conventional instruments, RACs intentionally allow fixed-cost ‘rent payments’ to fluctuate. We investigate the whole-farm risk reduction potential of different types of RACs via a historical simulation....

FVA is defined in a consistent way with NSFR such that the new framework of FVA monitors the costs due to keeping NSFR at an acceptable level, as well. In addition, the problem of choosing the optimal funding strategy is formulated as a shortest path problem where the proposed FVA framework is applied in the optimization process.

  8. A Review of Recent RTO Benefit-Cost Studies: Toward MoreComprehensive Assessments of FERC Electricity RestructuringPolicies

    Energy Technology Data Exchange (ETDEWEB)

    Eto, Joseph H.; Lesieutre, Bernard C.

    2005-12-01

    During the past three years, government and private organizations have issued more than a dozen studies of the benefits and costs of Regional Transmission Organizations (RTOs). Most of these studies have focused on benefits that can be readily estimated using traditional production-cost simulation techniques, which compare the cost of centralized dispatch under an RTO to dispatch in the absence of an RTO, and on costs associated with RTO start-up and operation. Taken as a whole, it is difficult to draw definitive conclusions from these studies because they have not examined potentially much larger benefits (and costs) resulting from the impacts of RTOs on reliability management, generation and transmission investment and operation, and wholesale electricity market operation. This report: (1) Describes the history of benefit-cost analysis of FERC electricity restructuring policies; (2)Reviews current practice by analyzing 11 RTO benefit-cost studies that were published between 2002 and 2004 and makes recommendations to improve the documentation of data and methods and the presentation of findings in future studies that focus primarily on estimating short-run economic impacts; and (3) Reviews important impacts of FERC policies that have been overlooked or incompletely treated by recent RTO benefit-cost studies and the challenges to crafting more comprehensive assessments of these impacts based on actual performance, including impacts on reliability management, generation and transmission investment and operation, and wholesale electricity market operation.

  9. Portfolio balancing and risk adjusted values under constrained budget conditions

    International Nuclear Information System (INIS)

    MacKay, J.A.; Lerche, I.

    1996-01-01

    For a given hydrocarbon exploration opportunity, the influences of value, cost, success probability and corporate risk tolerance provide an optimal working interest that should be taken in the opportunity in order to maximize the risk adjusted value. When several opportunities are available, but when the total budget is insufficient to take optimal working interest in each, an analytic procedure is given for optimizing the risk adjusted value of the total portfolio; the relevant working interests are also derived based on a cost exposure constraint. Several numerical illustrations are provided to exhibit the use of the method under different budget conditions, and with different numbers of available opportunities. When value, cost, success probability, and risk tolerance are uncertain for each and every opportunity, the procedure is generalized to allow determination of probable optimal risk adjusted value for the total portfolio and, at the same time, the range of probable working interest that should be taken in each opportunity is also provided. The result is that the computations of portfolio balancing can be done quickly in either deterministic or probabilistic manners on a small calculator, thereby providing rapid assessments of opportunities and their worth to a corporation.

    Kornacki, Jeffrey L.

    Seventy-six million cases of foodborne disease occur each year in the United States alone. Medical and lost productivity costs of the most common pathogens are estimated to be 5.6-9.4 billion. Product recalls, whether from foodborne illness or spoilage, result in added costs to manufacturers in a variety of ways. These may include expenses associated with lawsuits from real or allegedly stricken individuals and lawsuits from shorted customers. Other costs include those associated with efforts involved in finding the source of the contamination and eliminating it and include time when lines are shut down and therefore non-productive, additional non-routine testing, consultant fees, time and personnel required to overhaul the entire food safety system, lost market share to competitors, and the cost associated with redesign of the factory and redesign or acquisition of more hygienic equipment. The cost associated with an effective quality assurance plan is well worth the effort to prevent the situations described.

    This report was prepared to support development of the Department of Energy Environmental Management cost infrastructure -- a new capability to independently estimate and analyze costs. Currently, the cost data are reported according to a structure that blends level of effort tasks with product and process oriented tasks. Also. the budgetary inputs are developed from prior year funding authorizations and from contractor-developed parametric estimates that have been adjusted to planned funding levels or appropriations. Consequently, it is difficult for headquarters and field-level activities to use actual cost data and technical requirements to independently assess the costs generated and identify trends, potential cost savings from process improvements, and cost reduction strategies

    The linear Halbach array is a well-known planar magnetic structure capable, in the idealized case, of generating a one-sided magnetic field. We show that such a field can be created from an array of uniformly magnetized rods, and rotating these rods in an alternating fashion can smoothly transfer the resultant magnetic field through the plane of the device. We examine an idealized model composed of infinite line dipoles and carry out computational simulations on a realizable device using a magnetic boundary element method. Such an arrangement can be used for an efficient latching device, or to produce a highly tunable field in the space above the device. - Highlights: Black-Right-Pointing-Pointer We model an adjustable 'one-sided' flux sheet made up of a series of dipolar magnetic field sources. Black-Right-Pointing-Pointer We show that magnetic field can be switched from one side of sheet to other by a swap rotation of each of magnetic sources. Black-Right-Pointing-Pointer Investigations show that such an arrangement is practical and can easily be fabricated.

  5. Control of Adjustable Compliant Actuators

    Directory of Open Access Journals (Sweden)

    Berno J.E. Misgeld

    2014-05-01

    Full Text Available Adjustable compliance or variable stiffness actuators comprise an additional element to elastically decouple the actuator from the load and are increasingly applied to human-centered robotic systems. The advantages of such actuators are of paramount importance in rehabilitation robotics, where requirements demand safe interaction between the therapy system and the patient. Compliant actuator systems enable the minimization of large contact forces arising, for example, from muscular spasticity and have the ability to periodically store and release energy in cyclic movements. In order to overcome the loss of bandwidth introduced by the elastic element and to guarantee a higher range in force/torque generation, new actuator designs consider variable or nonlinear stiffness elements, respectively. These components cannot only be adapted to the walking speed or the patient condition, but also entail additional challenges for feedback control. This paper introduces a novel design method for an impedance-based controller that fulfills the control objectives and compares the performance and robustness to a classical cascaded control approach. The new procedure is developed using a non-standard positive-real Η2 controller design and is applied to a loop-shaping approach. Robust norm optimal controllers are designed with regard to the passivity of the actuator load-impedance transfer function and the servo control problem. Classical cascaded and positive-real Η2 controller designs are validated and compared in simulations and in a test bench using a passive elastic element of varying stiffness.

    Direct insurance claims tabulation and risk adjustment statistical methods can be used to estimate health care costs associated with various diseases. In this third manuscript derived from the new national Burden of Skin Disease Report from the American Academy of Dermatology, a risk adjustment method that was based on modeling the average annual costs of individuals with or without specific diseases, and specifically tailored for 24 skin disease categories, was used to estimate the economic burden of skin disease. The results were compared with the claims tabulation method used in the first 2 parts of this project. The risk adjustment method estimated the direct health care costs of skin diseases to be $46 billion in 2013, approximately $15 billion less than estimates using claims tabulation. For individual skin diseases, the risk adjustment cost estimates ranged from 11% to 297% of those obtained using claims tabulation for the 10 most costly skin disease categories. Although either method may be used for purposes of estimating the costs of skin disease, the choice of method will affect the end result. These findings serve as an important reference for future discussions about the method chosen in health care payment models to estimate both the cost of skin disease and the potential cost impact of care changes.

    2009-01-01

    This article studies the cost function for the natural gas transmission industry. 60 years ago, Hollis B. Chenery published an important contribution that demonstrated how, in that particular industry, the production function of micro-economic theory can be rewritten with engineering variables (Chenery, 1949). In 2008, an article published in The Engineering Economist (Yepez, 2008) provided a refreshing revival on Chenery's seminal thoughts. In addition to a tribute to the late H.B. Chenery, this document offers some further comments and extensions on Yepez (2008). It provides a statistically estimated characterisation of the long-run scale economies and a discussion on the short-run economics of the duplication of existing equipments. As a first extension, we study the optimal design for infrastructure that is planned to transport a seasonally-varying flow of natural gas. The second extension analyzes the optimal degree of excess capacity to be built into a new infrastructure by a firm that expects a random rise in its output during the infrastructure's lifetime.

  10. Laboratory cost and utilization containment.

    Steiner, J W; Root, J M; White, D C

    1991-01-01

    The authors analyzed laboratory costs and utilization in 3,771 cases of Medicare inpatients admitted to a New England academic medical center ("the Hospital") from October 1, 1989 to September 30, 1990. The data were derived from the Hospital's Decision Resource System comprehensive data base. The authors established a historical reference point for laboratory costs as a percentage of total inpatient costs using 1981-82 Medicare claims data and cost report information. Inpatient laboratory costs were estimated at 9.5% of total inpatient costs for pre-Diagnostic Related Groups (DRGs) Medicare discharges. Using this reference point and adjusting for the Hospital's 1990 case mix, the "expected" laboratory cost was 9.3% of total cost. In fact, the cost averaged 11.5% (i.e., 24% above the expected cost level), and costs represented an even greater percentage of DRG reimbursement at 12.9%. If we regard the reimbursement as a total cost target (to eliminate losses from Medicare), then that 12.9% is 39% above the "expected" laboratory proportion of 9.3%. The Hospital lost an average of $1,091 on each DRG inpatient. The laboratory contributed 29% to this loss per case. Compared to other large hospitals, the Hospital was slightly (3%) above the mean direct cost per on-site test and significantly (58%) above the mean number of inpatient tests per inpatient day compared to large teaching hospitals. The findings suggest that careful laboratory cost analyses will become increasingly important as the proportion of patients reimbursed in a fixed manner grows. The future may hold a prospective zero-based laboratory budgeting process based on predictable patterns of DRG admissions or other fixed-reimbursement admission and laboratory utilization patterns.

  11. Artificial muscles with adjustable stiffness

    International Nuclear Information System (INIS)

    Mutlu, Rahim; Alici, Gursel

    2010-01-01

    This paper reports on a stiffness enhancement methodology based on using a suitably designed contact surface with which cantilevered-type conducting polymer bending actuators are in contact during operation. The contact surface constrains the bending behaviour of the actuators. Depending on the topology of the contact surface, the resistance of the polymer actuators to deformation, i.e. stiffness, is varied. As opposed to their predecessors, these polymer actuators operate in air. Finite element analysis and modelling are used to quantify the effect of the contact surface on the effective stiffness of a trilayer cantilevered beam, which represents a one-end-free, the-other-end-fixed polypyrrole (PPy) conducting polymer actuator under a uniformly distributed load. After demonstrating the feasibility of the adjustable stiffness concept, experiments were conducted to determine the stiffness of bending-type conducting polymer actuators in contact with a range (20–40 mm in radius) of circular contact surfaces. The numerical and experimental results presented demonstrate that the stiffness of the actuators can be varied using a suitably profiled contact surface. The larger the radius of the contact surface is, the higher is the stiffness of the polymer actuators. The outcomes of this study suggest that, although the stiffness of the artificial muscles considered in this study is constant for a given geometric size, and electrical and chemical operation conditions, it can be changed in a nonlinear fashion to suit the stiffness requirement of a considered application. The stiffness enhancement methodology can be extended to other ionic-type conducting polymer actuators

Also the user-friendliness of the spreadsheet tool must be improved in future versions of the model. The CMDP is presently closing its second phase, where it has been extended to include the OAIS Functional Entity Ingest. This has also enabled us to adjust the theoretical model further, especially regarding the accuracy and precision of the model and in relation to the underlying parameters used in the equations, such as migration frequency and format complexity. Understanding the nature of digital preservation cost is prerequisite for increasing the overall efficiency, and achieving first quality for preservation of cultural heritage materials.

  18. Proposal for a national inventory adjustment for trade in the presence of border carbon adjustment: Assessing carbon tax policy in Japan

    International Nuclear Information System (INIS)

    Zhou, Xin; Yano, Takashi; Kojima, Satoshi

    2013-01-01

    In this paper we pointed out a hidden inequality in accounting for trade-related emissions in the presence of border carbon adjustment. Under a domestic carbon pricing policy, producers pay for the carbon costs in exchange for the right to emit. Under border carbon adjustment, however, the exporting country pays for the carbon costs of their exports to the importing country but not be given any emission credits. As a result, export-related emissions will be remained in the national inventory of the exporting country based on the UNFCCC inventory approach. This hidden inequality is important to climate policy but has not yet been pointed out. To address this issue we propose a method of National Inventory Adjustment for Trade, by which export-related emissions will be deducted from the national inventory of the exporting country and added to the national inventory of the importing country which implements border carbon adjustment. To assess the policy impacts, we simulated a carbon tax policy with border tax adjustment for Japan using a multi-region computable general equilibrium model. The results indicate that with the National Inventory Adjustment for Trade, both Japan′s national inventory and the carbon leakage effects of Japan′s climate policy will be greatly different. - Highlights: • The inequality in GHG accounting caused by border carbon adjustment presented. • National inventory adjustment for trade under border carbon adjustment proposed. • Policy impacts on international competitiveness and carbon leakage assessed. • Practical issues related to the national inventory adjustment for trade discussed

    The primary purpose of this study is to assess the existing evidence on the cost-effectiveness of surgical interventions for the management of knee and hip osteoarthritis by systematically reviewing published economic evaluation studies. A systematic review was conducted for the period 2004 to 2016. Electronic databases were searched to identify both trial and model based economic evaluation studies that evaluated surgical interventions for knee and hip osteoarthritis. A total of 23 studies met the inclusion criteria and an assessment of these studies showed that total knee arthroplasty (TKA), and total hip arthroplasty (THA) showed evidence of cost-effectiveness and improvement in quality of life of the patients when compared to non-operative and non-surgical procedures. On the other hand, even though delaying TKA and THA may lead to some cost savings in the short-run, the results from the study showed that this was not a cost-effective option. TKA and THA are cost-effective and should be recommended for the management of patients with end stage/severe knee and hip OA. However, there needs to be additional studies to assess the cost-effectiveness of other surgical interventions in order for definite conclusions to be reached.

    1992-01-01

    Neutron spectrum adjustment method is shortly reviewed. Practical example dealing with power reactor pressure vessel exposure rates determination is analysed. Adjusted exposure rates are found only slightly affected by the covariances of measured reaction rates and activation cross sections, while the multigroup spectra covariances were found important. Approximate spectra covariance matrices, as suggested in Astm E944-89, were found useful but care is advised if they are applied in adjustments of spectra at locations without dosimetry.

    This study examines the impact of HMO penetration and competition on health system performance, as measured by hospital cost per adjusted admissions. The study population consisted of acute-care hospitals in the United States. The findings of this study suggest that there is no relationship between HMO competition and hospital cost per adjusted admission. Governmental efforts to stimulate competition in the hospital market, if focused on promoting HMOs, are not likely to produce cost-containing results quickly.

  4. Cost allocation review : staff discussion paper

    2005-09-01

    This report addressed the need for updated cost allocation studies filed by local electricity distribution companies because they ensure that distribution rates for each customer class remain just and reasonable. According to the 2001 Electricity Distribution Rate Handbook, the Ontario Energy Board requires new cost allocation studies before implementing any future incentive regulation plans. A review of cost allocations allows the Board to consider the need for adjustments to the current share of distribution costs paid by different classes of ratepayers. This report included 14 sections to facilitate consultations with stakeholders on financial information requirements for cost allocation; directly assignable costs; functionalization; categorization; allocation methods; allocation of other costs; load data requirements; cost allocation implementation issues; addition of new rate class and rate design for scattered unmetered loads; addition of new rate class for larger users; rates to charge embedded distributors; treatment of the rate sub-classification identified as time-of-use; and, rate design implementation issues. 1 fig., 7 appendices

    Because of rising drug expenditures, cost considerations have become essential, necessitating the requirement for cost-effectiveness analyses for managed care organizations (MCOs). The study objective is to examine the impact of various drug-cost components, in addition to wholesale acquisition cost (WAC), on the cost-effectiveness of osteoporosis therapies. A Markov model of osteoporosis was used to exemplify different drug cost scenarios. We examined the effect of varying rebates for oral bisphosphonates--risedronate and ibandronate--as well as considering the impact of varying copayments and administration costs for intravenous zoledronate. The population modeled was 1,000 American women, > or = 50 years with osteoporosis. Patients were followed for 1 year to reflect an annual budget review of formularies by MCOs. The cost of therapy was based on an adjusted WAC, and is referred to as net drug cost. The total annual cost incurred by an MCO for each drug regimen was calculated using the net drug cost and fracture cost. We estimated cost on a quality adjusted life year (QALY) basis. When considering different rebates, results for risedronate versus ibandronate vary from cost-savings (i.e., costs less and more effective) to approximately $70,000 per QALY. With no risedronate rebate, an ibandronate rebate of approximately 65% is required before cost per QALY surpasses $50,000. With rebates greater than 25% for risedronate, irrespective of ibandronate rebates, results become cost-saving. Results also showed the magnitude of cost savings to the MCO varied by as much as 65% when considering no administration cost and the highest coinsurance rate for zoledronate. Our study showed that cost-effectiveness varies considerably when factors in addition to the WAC are considered. This paper provides recommendations for pharmaceutical manufacturers and MCOs when developing and interpreting such analyses.

    Turkish electricity sector has undergone significant institutional changes since 1984. The recent developments since 2001 including the setting up of a regulatory agency to undertake the regulation of the sector and increasing participation of private investors in the field of electricity generation are of special interest. This paper estimates cost functions and investigates the degree of scale economies, overinvestment, and technological progress in the Turkish electricity generation sector for the period 1984-2006 using long-run and short-run translog cost functions. Estimations were done for six groups of firms, public and private. The results indicate existence of scale economies throughout the period of analysis, hence declining long-run average costs. The paper finds empirical support for the Averch-Johnson effect until 2001, i.e., firms overinvested in an environment where there are excess returns to capital. But this effect was reduced largely after 2002. Technological progress deteriorated slightly from 1984-1993 to 1994-2001 but improved after 2002. Overall, the paper found that regulation of the market under the newly established regulating agency after 2002 was effective and there are potential gains from such regulation. (author)

    Full Text Available Objectives: Previous research on the association between adjustment latitude (defined as the opportunity to adjust work efforts in case of illness and sickness absence and sickness presence has produced inconsistent results. In particular, low adjustment latitude has been identified as both a risk factor and a deterrent of sick leave. The present study uses an alternative analytical strategy with the aim of joining these results together. Material and Methods: Using a cross-sectional design, a random sample of employees covered by the Upper Austrian Sickness Fund (N = 930 was analyzed. Logistic and ordinary least square (OLS regression models were used to examine the association between adjustment latitude and days of sickness absence, sickness presence, and an estimator for the individual sickness absence and sickness presence propensity. Results: A high level of adjustment latitude was found to be associated with a reduced number of days of sickness absence and sickness presence, but an elevated propensity for sickness absence. Conclusions: Employees with high adjustment latitude experience fewer days of health complaints associated with lower rates of sick leave and sickness presence compared to those with low adjustment latitude. In case of illness, however, high adjustment latitude is associated with a higher pro­bability of taking sick leave rather than sickness presence.

    1991-01-01

    This paper reports on the cost restructuring of the petroleum industry. This current decade is likely to be one of the most challenging for the petroleum industry. Though petroleum remains among the world's biggest businesses, news of consolidations, restructuring, and layoffs permeates the oil patch from the Gulf of Mexico to the Arctic Isles. The recessionary economy has accelerated these changes, particularly in the upstream sector. Today, even the best-managed companies are transforming their cost structures, and companies that fail to do likewise probably won't survive as independent companies. Indeed, significant consolidation took place during the 1980s. More consolidations can be expected in this decade for companies that do not adapt to the economic realities of the mature business

    Silverstein, Marshall L; Mavrolefteros, George; Close, David

    2002-01-01

    To examine the relationship between premorbid adjustment and neuropsychological deficit in schizophrenia, this report examined retrospective ratings of social and school adjustment during three age epochs (childhood, early adolescence, and late adolescence) as predictors of neurocognitive performance in 61 clinically and pharmacologically stabilized schizophrenia outpatients. Results indicated greater cognitive deficits when premorbid adjustment was unfavorable, particularly for measures of attention and executive functions. Premorbid number and quality of peer relationships and psychosocial adaptation to the school environment were more closely related to neuropsychological performance during adulthood than were premorbid withdrawal and premorbid academic performance. Early onset of poor premorbid adjustment rather than deterioration from childhood to adolescence was associated with greater neuropsychological disturbance in adulthood. It is suggested that childhood onset of premorbid deficits in selective areas of social and academic adjustment appears to influence the cognitive performance seen in adult schizophrenia. This study is consistent with findings from other related reports; it extends these findings to a larger and clinically stabilized sample.

  8. The impact of ownership unbundling on cost efficiency: Empirical evidence from the New Zealand electricity distribution sector

    International Nuclear Information System (INIS)

    Filippini, Massimo; Wetzel, Heike

    2014-01-01

    Several countries around the world have introduced reforms to the electric power sector. One important element of these reforms is the introduction of an unbundling process, i.e., the separation of the competitive activities of supply and production from the monopole activity of transmission and distribution of electricity. There are several forms of unbundling: functional, legal and ownership. New Zealand, for instance, adopted an ownership unbundling in 1998. As discussed in the literature, ownership unbundling produces benefits and costs. One of the benefits may be an improvement in the level of the productive efficiency of the companies due to the use of the inputs in just one activity and a greater level of transparency for the regulator. This paper analyzes the cost efficiency of 28 electricity distribution companies in New Zealand for the period between 1996 and 2011. Using a stochastic frontier panel data model, a total cost function and a variable cost function are estimated in order to evaluate the impact of ownership unbundling on the level of cost efficiency. The results indicate that ownership separation of electricity generation and retail operations from the distribution network has a positive effect on the cost efficiency of distribution companies in New Zealand. The estimated effect of ownership separation suggests a positive average one-off shift in the level of cost efficiency by 0.242 in the short-run and 0.144 in the long-run. - Highlights: • We analyze the impact of ownership unbundling on the level of cost efficiency. • A variable cost frontier function and a total cost frontier function are estimated. • The results suggest a positive one-off shift in the level of cost efficiency

  9. The Quality Adjusted Life Year: A Total-Utility Perspective.

    Science.gov (United States)

    Firth, Steven J

    2018-04-01

    Given that a properly formed utilitarian response to healthcare distribution issues should evaluate cost effectiveness against the total utility increase, it follows that any utilitarian cost-effectiveness metric should be sensitive to increases in both individual and social utility afforded by a given intervention. Quality adjusted life year (QALY) based decisionmaking in healthcare cannot track increases in social utility, and as a result, the QALY cannot be considered a strict utilitarian response to issues of healthcare distribution. This article considers arguments against, and a possible defence of, the QALY as a utilitarian concept; in response, the article offers a similar - but properly formed - utilitarian metric called the (IALY). This article also advances a tool called the 'glee factor' (GF) on which the IALY may lean in a similar way to which the QALY leans on the Rosser Index.

  10. Do insurers respond to risk adjustment? A long-term, nationwide analysis from Switzerland.

    Science.gov (United States)

    von Wyl, Viktor; Beck, Konstantin

    2016-03-01

    Community rating in social health insurance calls for risk adjustment in order to eliminate incentives for risk selection. Swiss risk adjustment is known to be insufficient, and substantial risk selection incentives remain. This study develops five indicators to monitor residual risk selection. Three indicators target activities of conglomerates of insurers (with the same ownership), which steer enrollees into specific carriers based on applicants' risk profiles. As a proxy for their market power, those indicators estimate the amount of premium-, health care cost-, and risk-adjustment transfer variability that is attributable to conglomerates. Two additional indicators, derived from linear regression, describe the amount of residual cost differences between insurers that are not covered by risk adjustment. All indicators measuring conglomerate-based risk selection activities showed increases between 1996 and 2009, paralleling the establishment of new conglomerates. At their maxima in 2009, the indicator values imply that 56% of the net risk adjustment volume, 34% of premium variability, and 51% cost variability in the market were attributable to conglomerates. From 2010 onwards, all indicators decreased, coinciding with a pre-announced risk adjustment reform implemented in 2012. Likewise, the regression-based indicators suggest that the volume and variance of residual cost differences between insurers that are not equaled out by risk adjustment have decreased markedly since 2009 as a result of the latest reform. Our analysis demonstrates that risk-selection, especially by conglomerates, is a real phenomenon in Switzerland. However, insurers seem to have reduced risk selection activities to optimize their losses and gains from the latest risk adjustment reform.

    Full Text Available Since alendronate became available in generic form in the Unites States in 2008, its price has been decreasing. The objective of this study was to investigate the impact of alendronate cost on the cost-effectiveness of osteoporosis screening and treatment in postmenopausal women.Microsimulation cost-effectiveness model of osteoporosis screening and treatment for U.S. women age 65 and older. We assumed screening initiation at age 65 with central dual-energy x-ray absorptiometry (DXA, and alendronate treatment for individuals with osteoporosis; with a comparator of "no screening" and treatment only after fracture occurrence. We evaluated annual alendronate costs of $20 through $800; outcome measures included fractures; nursing home admission; medication adverse events; death; costs; quality-adjusted life-years (QALYs; and incremental cost-effectiveness ratios (ICERs in 2010 U.S. dollars per QALY gained. A lifetime time horizon was used, and direct costs were included. Base-case and sensitivity analyses were performed.Base-case analysis results showed that at annual alendronate costs of $200 or less, osteoporosis screening followed by treatment was cost-saving, resulting in lower total costs than no screening as well as more QALYs (10.6 additional quality-adjusted life-days. When assuming alendronate costs of $400 through $800, screening and treatment resulted in greater lifetime costs than no screening but was highly cost-effective, with ICERs ranging from $714 per QALY gained through $13,902 per QALY gained. Probabilistic sensitivity analyses revealed that the cost-effectiveness of osteoporosis screening followed by alendronate treatment was robust to joint input parameter estimate variation at a willingness-to-pay threshold of $50,000/QALY at all alendronate costs evaluated.Osteoporosis screening followed by alendronate treatment is effective and highly cost-effective for postmenopausal women across a range of alendronate costs, and may be cost

  13. Role of Osmotic Adjustment in Plant Productivity

    Energy Technology Data Exchange (ETDEWEB)

    Gebre, G.M.

    2001-01-11

    Successful implementation of short rotation woody crops requires that the selected species and clones be productive, drought tolerant, and pest resistant. Since water is one of the major limiting factors in poplar (Populus sp.) growth, there is little debate for the need of drought tolerant clones, except on the wettest of sites (e.g., lower Columbia River delta). Whether drought tolerance is compatible with productivity remains a debatable issue. Among the many mechanisms of drought tolerance, dehydration postponement involves the maintenance of high leaf water potential due to, for example, an adequate root system. This trait is compatible with productivity, but requires available soil moisture. When the plant leaf water potential and soil water content decline, the plant must be able to survive drought through dehydration tolerance mechanisms, such as low osmotic potential or osmotic adjustment. Osmotic adjustment and low osmotic potential are considered compatible with growth and yield because they aid in the maintenance of leaf turgor. However, it has been shown that turgor alone does not regulate cell expansion or stomatal conductance and, therefore, the role of osmotic adjustment is debated. Despite this finding, osmotic adjustment has been correlated with grain yield in agronomic crop species, and gene markers responsible for osmotic adjustment are being investigated to improve drought tolerance in productive progenies. Although osmotic adjustment and low osmotic potentials have been investigated in several forest tree species, few studies have investigated the relationship between osmotic adjustment and growth. Most of these studies have been limited to greenhouse or container-grown plants. Osmotic adjustment and rapid growth have been specifically associated in Populus and black spruce (Picea mariuna (Mill.) B.S.P.) progenies. We tested whether these relationships held under field conditions using several poplar clones. In a study of two hybrid poplar

Living in a prison for long time becomes difficult for all inmates. So they often face adjustment and mental health problems. Recent findings suggest that mental illness rate in prison is three times higher than in the general population. Objective: The aim of the present study was to investigate the adjustment and the mental health problem and its relation in the prisoners. Materials and Methods : In the present study, 37 male prisoners of district jail of Dhanbad District of Jharkhand were selected on purposive sampling basis. Each prisoner was given specially designed Performa - Personal Data Sheet, General Health Questionnaire-12 and Bell Adjustment Inventory. Appropriate statistical tools were used to analyze the data. Results: The results obtained showed poor adjustment in social and emotional areas on the adjustment scale. The study also revealed a significant association between adjustment and mental health problem in the prisoners. Conclusion: The prisoners were found to have poor social and emotional adjustment which has strong association with their mental health.

    Volk, James T.

    2001-01-01

    The proposed Next Linear Collider (NLC) will require over 1400 adjustable quadrupoles between the main linacs' accelerator structures. These 12.7 mm bore quadrupoles will have a range of integrated strength from 0.6 to 138 Tesla, with a maximum gradient of 141 Tesla per meter, an adjustment range of +0 to -20% and effective lengths from 324 mm to 972 mm. The magnetic center must remain stable to within 1 micron during the 20% adjustment. In an effort to reduce costs and increase reliability, several designs using hybrid permanent magnets have been developed. Four different prototypes have been built. All magnets have iron poles and use Samarium Cobalt to provide the magnetic fields. Two use rotating permanent magnetic material to vary the gradient, one uses a sliding shunt to vary the gradient and the fourth uses counter rotating magnets. Preliminary data on gradient strength, temperature stability, and magnetic center position stability are presented. These data are compared to an equivalent electromagnetic prototype

  1. Nuclear data adjustment methodology utilizing resonance parameter sensitivities and uncertainties

    International Nuclear Information System (INIS)

    Broadhead, B.L.

    1983-01-01

    This work presents the development and demonstration of a Nuclear Data Adjustment Method that allows inclusion of both energy and spatial self-shielding into the adjustment procedure. The resulting adjustments are for the basic parameters (i.e. resonance parameters) in the resonance regions and for the group cross sections elsewhere. The majority of this development effort concerns the production of resonance parameter sensitivity information which allows the linkage between the responses of interest and the basic parameters. The resonance parameter sensitivity methodology developed herein usually provides accurate results when compared to direct recalculations using existng and well-known cross section processing codes. However, it has been shown in several cases that self-shielded cross sections can be very non-linear functions of the basic parameters. For this reason caution must be used in any study which assumes that a linear relatonship exists between a given self-shielded group cross section and its corresponding basic data parameters. The study also has pointed out the need for more approximate techniques which will allow the required sensitivity information to be obtained in a more cost effective manner

  2. Retrofitting adjustable speed drives for large induction motors

    Wuestefeld, M.R.; Merriam, C.H.; Porter, N.S.

    2004-01-01

    Adjustable speed drives (ASDs) are used in many power plants to control process flow by varying the speed of synchronous and induction motors. In applications where the flow requirements vary significantly, ASDs reduce energy and maintenance requirements when compared with drag valves, dampers or other methods to control flow. Until recently, high horsepower ASDs were not available for induction motors. However, advances in power electronics technology have demonstrated the reliability and cost effectiveness of ASDs for large horsepower induction motors. Emphasis on reducing operation and maintenance costs and increasing the capacity factor of nuclear power plants has led some utilities to consider replacing flow control devices in systems powered by large induction motors with ASDs. ASDs provide a high degree of reliability and significant energy savings in situations where full flow operation is not needed for a substantial part of the time. This paper describes the basic adjustable speed drive technologies available for large induction motor applications, ASD operating experience and retrofitting ASDs to replace the existing GE Boiling Water Reactor recirculation flow control system

  3. The costs of delay in infrastructure investments: A comparison of 2001 and 2014 household water supply coping costs in the Kathmandu Valley, Nepal

    In 2001, we conducted a survey of 1500 randomly sampled households in Kathmandu to determine the costs people were incurring to cope with Kathmandu's poor quality, unreliable piped water supply system. From 2001 until 2014, there was little additional public investment in the municipal water supply system. In the summer of 2014, we attempted to reinterview all 1500 households in our 2001 sample to determine how they had managed to deal with the growing water shortage and the deteriorating condition of the piped water infrastructure in Kathmandu and to compare their coping costs in 2014 with those we first estimated in 2001. Average household coping costs more than doubled in real terms over the period from 2001 to 2014, from US5 to US12 per month (measured in 2014 prices). The composition of household coping costs changed from 2001 to 2014, as households responded to the deteriorating condition of the piped water infrastructure by drilling more private wells, purchasing water from both tanker truck and bottled water vendors, and installing more storage tanks. These investments and expenditures resulted in a decline in the time households spend collecting water from outside the home. Our analysis suggests that the significant increase in coping costs between 2001 and 2014 may provide an opportunity for the municipal water utility to substantially increase water tariffs if the quantity and quality of piped services can be improved. However, the capital investments made by some households in private wells, pumping and treatment systems, and storage tanks in response to the delay in infrastructure investment may lock them into current patterns of water use, at least in the short run, and thus make it difficult to predict how they would respond to tariff increases for improved piped water services.

    1988-01-01

    The nature of climate impacts and adjustment in water supply and flood management is discussed, and a case study of water manager response to climate fluctuation in California's Sacramento Basin is presented. The case illuminates the effect on climate impact and response of traditional management approaches, the dynamic qualities of maturing water systems, socially imposed constraints, and climate extremes. A dual pattern of crisis-response and gradual adjustment emerges, and specific mechanisms for effecting adjustment of water management systems are identified. The case study, and broader trends in US water development, suggest that oversized structural capacity, the traditional adjustment to climate variability in water resources, may prove less feasible in the future as projects become smaller and new facilities are delayed by economic and environmental concerns.

    This study was conducted to examine the association between marital adjustment and psychological distress in a large, probability sample of married adults in Japan (N = 710) from the Midlife Development in Japan (MIDJA) study. Results indicate that positive and negative dimensions of marital adjustment were significantly associated with dimensional and categorical measures of psychological distress. Furthermore, the associations between marital adjustment and psychological distress remained significant when statistically controlling for neuroticism, quality of friend and family relationships, and demographic variables. These results demonstrate that the well-established association between marital adjustment and psychological distress found in European-American countries is also found in Japan. Findings support continued research on marital functioning and psychological distress in East Asian countries. PMID:28082761

    Full Text Available In this study, we investigate the speed of adjustment for leverage ratios of firms listed on Borsa Istanbul, in order to investigate the prediction of the trade-off theory, regarding capital structure rebalancing. For this purpose, we estimate the speed of adjustment by using Generalized Method of Moments system estimation technique. The results of this estimation suggest the speed of adjustment as approximately 29%. This significant speed of adjustment is consistent with the prediction of trade-off theory, which suggests that firms follow target capital structures and when the firms' leverage ratios deviate from these targets; they make financial decisions with the goal of closing the gap between the previous year's leverage and target leverage of the current period.

  15. An improved set of standards for finding cost for cost-effectiveness analysis.

    Barnett, Paul G

    2009-07-01

    Guidelines have helped standardize methods of cost-effectiveness analysis, allowing different interventions to be compared and enhancing the generalizability of study findings. There is agreement that all relevant services be valued from the societal perspective using a long-term time horizon and that more exact methods be used to cost services most affected by the study intervention. Guidelines are not specific enough with respect to costing methods, however. The literature was reviewed to identify the problems associated with the 4 principal methods of cost determination. Microcosting requires direct measurement and is ordinarily reserved to cost novel interventions. Analysts should include nonwage labor cost, person-level and institutional overhead, and the cost of development, set-up activities, supplies, space, and screening. Activity-based cost systems have promise of finding accurate costs of all services provided, but are not widely adopted. Quality must be evaluated and the generalizability of cost estimates to other settings must be considered. Administrative cost estimates, chiefly cost-adjusted charges, are widely used, but the analyst must consider items excluded from the available system. Gross costing methods determine quantity of services used and employ a unit cost. If the intervention will affect the characteristics of a service, the method should not assume that the service is homogeneous. Questions are posed for future reviews of the quality of costing methods. The analyst must avoid inappropriate assumptions, especially those that bias the analysis by exclusion of costs that are affected by the intervention under study.

  16. A comparative cost analysis of robotic-assisted surgery versus laparoscopic surgery and open surgery: the necessity of investing knowledgeably.

    Robotic surgery has been proposed as a minimally invasive surgical technique with advantages for both surgeons and patients, but is associated with high costs (installation, use and maintenance). The Health Technology Assessment Unit of the Bambino Gesù Children's Hospital sought to investigate the economic sustainability of robotic surgery, having foreseen its impact on the hospital budget METHODS: Break-even and cost-minimization analyses were performed. A deterministic approach for sensitivity analysis was applied by varying the values of parameters between pre-defined ranges in different scenarios to see how the outcomes might differ. The break-even analysis indicated that at least 349 annual interventions would need to be carried out to reach the break-even point. The cost-minimization analysis showed that robotic surgery was the most expensive procedure among the considered alternatives (in terms of the contribution margin). Robotic surgery is a good clinical alternative to laparoscopic and open surgery (for many pediatric operations). However, the costs of robotic procedures are higher than the equivalent laparoscopic and open surgical interventions. Therefore, in the short run, these findings do not seem to support the decision to introduce a robotic system in our hospital.

    Cavalli, Fausto; Naimzada, Ahmad

    2015-01-01

    Highlights: •A monopoly with isoelastic demand function is studied. •Reduced rationality monopolist uses gradient adjustment. •If marginal cost is small, increasing elasticity leads to stable dynamics. •For large marginal cost, dynamic can be unstable for both small and large elasticity. -- Abstract: We study a monopolistic market characterized by a constant elasticity demand function, in which the firm technology is described by a linear total cost function. The firm is assumed to be boundedly rational and to follow a gradient rule to adjust the production level in order to optimize its profit. We focus on what happens on varying the price elasticity of demand, studying the effect on the equilibrium stability. We prove that, depending on the relation between the market size and the marginal cost, two different scenarios are possible, in which elasticity has either a stabilizing or a mixed stabilizing/destabilizing effect

  19. Cost of depression in Europe.

    2006-06-01

    Depression is one of the most disabling diseases, and causes a significant burden both to the individual and to society. WHO data suggests that depression causes 6% of the burden of all diseases in Europe in terms of disability adjusted life years (DALYs). Yet, the knowledge of the economic impact of depression has been relatively little researched in Europe. The present study aims at estimating the total cost of depression in Europe based on published epidemiologic and economic evidence. A model was developed to combine epidemiological and economic data on depression in Europe to estimate the cost. The model was populated with data collected from extensive literature reviews of the epidemiology and economic burden of depression in Europe. The cost data was calculated as annual cost per patient, and epidemiologic data was reported as 12-month prevalence estimates. National and international statistics for the model were retrieved from the OECD and Eurostat databases. The aggregated annual cost estimates were presented in Euro for 2004. In 28 countries with a population of 466 million, at least 21 million were affected by depression. The total annual cost of depression in Europe was estimated at Euro 118 billion in 2004, which corresponds to a cost of Euro 253 per inhabitant. Direct costs alone totalled dollar 42 billion, comprised of outpatient care (Euro 22 billion), drug cost (Euro 9 billion) and hospitalization (Euro 10 billion). Indirect costs due to morbidity and mortality were estimated at Euro 76 billion. This makes depression the most costly brain disorder in Europe, accounting for 33% of the total cost. The cost of depression corresponds to 1% of the total economy of Europe (GDP). Our cost results are in good agreement with previous research findings. The cost estimates in the present study are based on model simulations for countries where no data was available. The predictability of our model is limited to the accuracy of the input data employed. As

    Lee, K H; Angus, D C; Abramson, N S

    1996-12-01

    To review the various outcomes from cardiopulmonary resuscitation (CPR), the factors that influence these outcomes, the costs associated with CPR, and the application of cost-analyses to CPR. Data used to prepare this article were drawn from published articles and work in progress. Articles were selected for their relevance to the subjects of CPR and cost-analysis by MEDLINE keyword search. The authors extracted all applicable data from the English literature. Cost-analysis studies of CPR programs are limited by the high variation in resources consumed and attribution of cost to these resources. Furthermore, cost projections have not been adjusted to reflect patient-dependent variation in outcome. Variation in the patient's underlying condition, presenting cardiac rhythm, time to provision of definitive CPR, and effective perfusion all influence final outcome and, consequently, influence the cost-effectiveness of CPR programs. Based on cost data from previous studies, preliminary estimates of the cost-effectiveness of CPR programs for all 6-month survivors of a large international multicenter collaborative trial are $406,605.00 per life saved (range $344,314.00 to $966,759.00), and $225,892.00 per quality-adjusted-life-year (range $191,286.00 to $537,088.00). Reported outcome from CPR has varied from reasonable rates of good recovery, including return to full employment to 100% mortality. Appropriate CPR is encouraged, but continued widespread application appears extremely expensive.

  2. Managerial adjustment and its limits: sequential fault in comparative perspective

    Directory of Open Access Journals (Sweden)

    Flávio da Cunha Rezende

    2008-01-01

    Full Text Available This article focuses on explanations for sequential faults in administrative reform. It deals with the limits of managerial adjustment in an approach that attempts to connect theory and empirical data, articulating three levels of analysis. The first level presents comparative evidence of sequential fault within reforms in national governments through a set of indicators geared toward understanding changes in the role of the state. In light of analyses of a representative set of comparative studies on reform implementation, the second analytical level proceeds to identify four typical mechanisms that are present in explanations on managerial adjustment faults. In this way, we seek to configure an explanatory matrix for theories on sequential fault. Next we discuss the experience of management reform in the Brazilian context, conferring special attention on one of the mechanisms that creates fault: the control dilemma. The major hypotheses that guide our article are that reforms lead to sequential fault and that there are at least four causal mechanisms that produce reforms: a transactions costs involved in producing reforms; b performance legacy; c predominance of fiscal adjustment and d the control dilemma. These mechanisms act separately or in concert, and act to decrease chances for a transformation of State managerial patterns. Major evidence that is analyzed in these articles lend consistency to the general argument that reforms have failed in their attempts to reduce public expenses, alter patterns of resource allocation, reduce the labor force and change the role of the State. Our major conclusion is that reforms fail sequentially and managerial adjustment displays considerable limitations, particularly those of a political nature.

  3. Size-Adjustable Microdroplets Generation Based on Microinjection

    Directory of Open Access Journals (Sweden)

    Shibao Li

    2017-03-01

    Full Text Available Microinjection is a promising tool for microdroplet generation, while the microinjection for microdroplets generation still remains a challenging issue due to the Laplace pressure at the micropipette opening. Here, we apply a simple and robust substrate-contacting microinjection method to microdroplet generation, presenting a size-adjustable microdroplets generation method based on a critical injection (CI model. Firstly, the micropipette is adjusted to a preset injection pressure. Secondly, the micropipette is moved down to contact the substrate, then, the Laplace pressure in the droplet is no longer relevant and the liquid flows out in time. The liquid constantly flows out until the micropipette is lifted, ending the substrate-contacting situation, which results in the recovery of the Laplace pressure at the micropipette opening, and the liquid injection is terminated. We carry out five groups of experiments whereupon 1600 images are captured within each group and the microdroplet radius of each image is detected. Then we determine the relationship among microdroplet radius, radius at the micropipette opening, time, and pressure, and, two more experiments are conducted to verify the relationship. To verify the effectiveness of the substrate-contacting method and the relationship, we conducted two experiments with six desired microdroplet radii are set in each experiment, by adjusting the injection time with a given pressure, and adjusting the injection pressure with a given time. Then, six arrays of microdroplets are obtained in each experiment. The results of the experiments show that the standard errors of the microdroplet radii are less than 2% and the experimental errors fall in the range of ±5%. The average operating speed is 20 microdroplets/min and the minimum radius of the microdroplets is 25 μm. This method has a simple experimental setup that enables easy manipulation and lower cost.

    Sepsis is associated with high mortality and treatment costs. International guidelines recommend the implementation of integrated sepsis protocols; however, the true cost and cost-effectiveness of these are unknown. To assess the cost-effectiveness of an integrated sepsis protocol, as compared with conventional care. Prospective cohort study of consecutive patients presenting with septic shock and enrolled in the institution's integrated sepsis protocol. Clinical and economic outcomes were compared with a historical control cohort. Beth Israel Deaconess Medical Center. Overall, 79 patients presenting to the emergency department with septic shock in the treatment cohort and 51 patients in the control group. An integrated sepsis treatment protocol incorporating empirical antibiotics, early goal-directed therapy, intensive insulin therapy, lung-protective ventilation, and consideration for drotrecogin alfa and steroid therapy. In-hospital treatment costs were collected using the hospital's detailed accounting system. The cost-effectiveness analysis was performed from the perspective of the healthcare system using a lifetime horizon. The primary end point for the cost-effectiveness analysis was the incremental cost per quality-adjusted life year gained. Mortality in the treatment group was 20.3% vs. 29.4% in the control group (p = .23). Implementing an integrated sepsis protocol resulted in a mean increase in cost of approximately $8,800 per patient, largely driven by increased intensive care unit length of stay. Life expectancy and quality-adjusted life years were higher in the treatment group; 0.78 and 0.54, respectively. The protocol was associated with an incremental cost of $11,274 per life-year saved and a cost of $16,309 per quality-adjusted life year gained. In patients with septic shock, an integrated sepsis protocol, although not cost-saving, appears to be cost-effective and compares very favorably to other commonly delivered acute care interventions.

  5. Defense waste transportation: cost and logistics studies

    1982-08-01

    Transportation of nuclear wastes from defense programs is expected to significantly increase in the 1980s and 1990s as permanent waste disposal facilities come into operation. This report uses models of the defense waste transportation system to quantify potential transportation requirements for treated and untreated contact-handled transuranic (CH-TRU) wastes and high-level defense wastes (HLDW). Alternative waste management strategies in repository siting, waste retrieval and treatment, treatment facility siting, waste packaging and transportation system configurations were examined to determine their effect on transportation cost and hardware requirements. All cost estimates used 1980 costs. No adjustments were made for future changes in these costs relative to inflation. All costs are reported in 1980 dollars. If a single repository is used for defense wastes, transportation costs for CH-TRU waste currently in surface storage and similar wastes expected to be generated by the year 2000 were estimated to be 109 million dollars. Recovery and transport of the larger buried volumes of CH-TRU waste will increase CH-TRU waste transportation costs by a factor of 70. Emphasis of truck transportation and siting of multiple repositories would reduce CH-TRU transportation costs. Transportation of HLDW to repositories for 25 years beginning in 1997 is estimated to cost $229 M in 1980 costs and dollars. HLDW transportation costs could either increase or decrease with the selection of a final canister configuration. HLDW transportation costs are reduced when multiple repositories exist and emphasis is placed on truck transport

  6. Topics in data adjustment theory and applications

    Hwang, R.N.

    1988-01-01

    The methodologies of the uncertainty analysis and data adjustment have been well-developed and widely used abroad since the early 70's. With limited amount of covariance data on the differential cross section and the integral experiments available at the time, their accomplishments are, indeed, astounding. The fundamental adjustment equations, however, remain qualitatively unchanged. For the past few year, extensive efforts on these subjects have also begun at ANL in order to utilize the massive amount of integral experiments accumulated over years to provide the basis for improving the reactor parameters encountered in various design calculations. Pertinent covariance matrices and sensitivity matrices of the existing integral experiments have been evaluated and systematically compiled in the data files along with the cross section covariance data derived from the ENDF-B/V for the 21 group structure currently under consideration. A production code GMADJ that provides the adjusted quantities for a large number of cross section types has been developed by Poenitz for routine applications. The primary purpose of the present paper is to improve understanding of the application oriented issues important to the data adjustment theory and the subsequent usage of the adjusted quantities in the design calculations in support of these activities. 30 refs., 12 figs., 5 tabs

    This paper presents quantitative estimates of the indirect cost of financial distress and its determinants. In order to measure the cost, this study estimates the annualized changes in industry-adjusted operation profit and sales from a year before the onset of distress to the resolution year. Using those approaches, the median of indirect financial distress cost is estimated between three and 11 percent annually. To the extent that the direct cost of financial distress reduces reported opera...

  8. Adjustment of the 235U Fission Spectrum

    The latest nuclear data are used to examine the sensitivity of the least squares adjustment of the 235 U fission spectrum to the measured reaction rates, dosimetry cross sections, and prior spectrum covariance matrix. All of these parameters were found to be very important in the spectrum adjustment. The most significant deficiency in the nuclear data is the absence of a good prior covariance matrix. Covariance matrices generated from analytic models of the fission spectra have been used in the past. This analysis reveals some unusual features in the covariance matrix produced with this approach. Specific needs are identified for improved nuclear data to better determine the 235 U spectrum. An improved 235 U covariance matrix and adjusted spectrum are recommended for use in radiation transport sensitivity analyses

    In accordance with recommendations made by the Finance Committee in November 2009 and decisions taken by the Council in December 2009, certain financial benefits have been adjusted with effect from 1 January 2010. An increase of 1.6% has been applied to the scale of basic salaries and to stipends paid to Fellows (Annexes R A 5 and R A 6 of the Staff Rules and Regulations, respectively). The adjusted amounts are available from the HR Department intranet site or from departmental secretariats. As a result of the evolution of the Geneva consumer price index, no adjustments have been made to the subsistence allowances of Paid Associates and Students (Annex R A 7 of the Staff Rules and Regulations). The following social benefits also remain unchanged: Family, child and infant allowances (Annex R A 3 of the Staff Rules and Regulations).

    Divorce is becoming increasingly widespread in Europe. In this study, I present an analysis of the role played by attachment style (secure, dismissing, preoccupied and fearful, plus the dimensions of anxiety and avoidance) in the adaptation to divorce. Participants comprised divorced parents (N = 40) from a medium-sized city in the Basque Country. The results reveal a lower proportion of people with secure attachment in the sample group of divorcees. Attachment style and dependence (emotional and instrumental) are closely related. I have also found associations between measures that showed a poor adjustment to divorce and the preoccupied and fearful attachment styles. Adjustment is related to a dismissing attachment style and to the avoidance dimension. Multiple regression analysis confirmed that secure attachment and the avoidance dimension predict adjustment to divorce and positive affectivity while preoccupied attachment and the anxiety dimension predicted negative affectivity. Implications for research and interventions with divorcees are discussed.

    This review of nursing home cost function research shows that certain provider and service characteristics are systematically associated with differences in the average cost of care. This information can be used to group providers for reasonable cost related rate-setting or to adjust their rates or rate ceilings. However, relationships between average cost and such service characteristics as patient mix, service intensity, and quality of care have not been fully delineated. Therefore, econometric cost functions cannot yet provide rate-setters with predictions about the cost of the efficient provision of nursing home care appropriate to patient needs. In any case, the design of reimbursement systems must be founded not only on technical information but also on public policy goals for long-term care. PMID:10309223

    2011-11-04

    The indirect medical education (IME) and disproportionate share hospital (DSH) adjustments to Medicare's prospective payment rates for inpatient services are generally intended to compensate hospitals for patient care costs related to teaching activities and care of low income populations. These adjustments were originally established based on the statistical relationships between IME and DSH and hospital costs. Due to a variety of policy considerations, the legislated levels of these adjustments may have deviated over time from these "empirically justified levels," or simply, "empirical levels." In this paper, we estimate the empirical levels of IME and DSH using 2006 hospital data and 2009 Medicare final payment rules. Our analyses suggest that the empirical level for IME would be much smaller than under current law-about one-third to one-half. Our analyses also support the DSH adjustment prescribed by the Affordable Care Act of 2010 (ACA)--about one-quarter of the pre-ACA level. For IME, the estimates imply an increase in costs of 1.88% for each 10% increase in teaching intensity. For DSH, the estimates imply that costs would rise by 0.52% for each 10% increase in the low-income patient share for large urban hospitals. Public Domain.

    The spectrum adjustment procedure was extended to simultaneous neutron and gamma spectrum adjustment, and the feasibility of this technique is demonstrated in the analysis of HFIR dosimetry experiments. Conditions in which gamma rays may contribute considerably to radiation damage in steels are discussed. Beryllium helium accumulation fluence monitors (HAFMs) were found to be good monitors in gamma fields of intensities high enough to contribute to steel embrittlement. Use of 237 Np, 238 U, and 9 Be HAFM as gamma dosimeters is proposed for high-dose irradiations in high-energy, high-intensity gamma fields

    This paper exposes the complexity and discrete characteristic of the adjustment disorder with reference to its clinical and scientific diagnosis. Even though the disorder occurs in frequent clinical circumstances after important life events, such as mobbing, burn-out, unemployment, divorce or separation, pregnancy denial, surgical operation or cancer, the adjustment disorder is often not considered in the diagnosis since better known disorders with similar symptoms prevail, such as major depression and anxiety disorder. Ten years ago, Bottéro had already noticed that the adjustment disorder diagnosis remained rather uncommon with reference to patients he was working with while Langlois assimilated this disorder with an invisible diagnosis. In order to maximize the data collection, we used the article review below and challenged their surveys and results: National Center for Biotechnology Information (NBCI - Pubmed) for international articles and Cairn.info for French literature. Moreover, we targeted the following keywords on the search engine and used articles, which had been published from 1 February 1975 to 31 January 2015: "adjustment", "adjustment disorder" and the French translation "trouble de l'adaptation". One hundred and ninety-one articles matched our search criteria. However, after a closer analysis, solely 105 articles were selected as being of interest. Many articles were excluded since they were related to non-psychiatric fields induced by the term "adaptation". Indeed, the number of corresponding articles found for the adjustment disorder literally pointed-out the lack of existing literature on that topic in comparison to more known disorders such as anxiety disorder (2661 articles) or major depression (5481 articles). This represents up to 50 times more articles in comparison to the number of articles we found on adjustment disorder and up to 20 times more articles for the eating disorder (1994), although the prevalence is not significantly

    Highlights: • Operation optimization model of a Distributed Energy System (DES). • Multi-objective strategy to optimize energy cost and exergy efficiency. • Exergy analysis in building energy supply systems. - Abstract: With the growing demand of energy on a worldwide scale, improving the efficiency of energy resource use has become one of the key challenges. Application of exergy principles in the context of building energy supply systems can achieve rational use of energy resources by taking into account the different quality levels of energy resources as well as those of building demands. This paper is on the operation optimization of a Distributed Energy System (DES). The model involves multiple energy devices that convert a set of primary energy carriers with different energy quality levels to meet given time-varying user demands at different energy quality levels. By promoting the usage of low-temperature energy sources to satisfy low-quality thermal energy demands, the waste of high-quality energy resources can be reduced, thereby improving the overall exergy efficiency. To consider the economic factor as well, a multi-objective linear programming problem is formulated. The Pareto frontier, including the best possible trade-offs between the economic and exergetic objectives, is obtained by minimizing a weighted sum of the total energy cost and total primary exergy input using branch-and-cut. The operation strategies of the DES under different weights for the two objectives are discussed. The operators of DESs can choose the operation strategy from the Pareto frontier based on costs, essential in the short run, and sustainability, crucial in the long run. The contribution of each energy device in reducing energy costs and the total exergy input is also analyzed. In addition, results show that the energy cost can be much reduced and the overall exergy efficiency can be significantly improved by the optimized operation of the DES as compared with the

    Examine cost differences between Consumer Operated Service Programs (COSPs) as possibly determined by a) size of program, b) use of volunteers and other donated resources, c) cost-of-living differences between program locales, d) COSP model applied, and e) delivery system used to implement the COSP model. As part of a larger evaluation of COSP, data on operating costs, enrollments, and mobilization of donated resources were collected for eight programs representing three COSP models (drop-in centers, mutual support, and education/advocacy training). Because the 8 programs were operated in geographically diverse areas of the US, costs were examined with and without adjustment for differences in local cost of living. Because some COSPs use volunteers and other donated resources, costs were measured with and without these resources being monetized. Scale of operation also was considered as a mediating variable for differences in program costs. Cost per visit, cost per consumer per quarter, and total program cost were calculated separately for funds spent and for resources donated for each COSP. Differences between COSPs in cost per consumer and cost per visit seem better explained by economies of scale and delivery system used than by cost-of-living differences between program locations or COSP model. Given others' findings that different COSP models produce little variation in service effectiveness, minimize service costs by maximizing scale of operation while using a delivery system that allows staff and facilities resources to be increased or decreased quickly to match number of consumers seeking services.

    Cash-based interventions (CBIs) increasingly are being used to deliver humanitarian assistance and there is growing interest in the cost-effectiveness of cash transfers for preventing undernutrition in emergency contexts. The objectives of this study were to assess the costs, cost-efficiency and cost-effectiveness in achieving nutrition outcomes of three CBIs in southern Pakistan: a 'double cash' (DC) transfer, a 'standard cash' (SC) transfer and a 'fresh food voucher' (FFV) transfer. Cash and FFVs were provided to poor households with children aged 6-48 months for 6 months in 2015. The SC and FFV interventions provided $14 monthly and the DC provided $28 monthly. Cost data were collected via institutional accounting records, interviews, programme observation, document review and household survey. Cost-effectiveness was assessed as cost per case of wasting, stunting and disability-adjusted life year (DALY) averted. Beneficiary costs were higher for the cash groups than the voucher group. Net total cost transfer ratios (TCTRs) were estimated as 1.82 for DC, 2.82 for SC and 2.73 for FFV. Yet, despite the higher operational costs, the FFV TCTR was lower than the SC TCTR when incorporating the participation cost to households, demonstrating the relevance of including beneficiary costs in cost-efficiency estimations. The DC intervention achieved a reduction in wasting, at $4865 per case averted; neither the SC nor the FFV interventions reduced wasting. The cost per case of stunting averted was $1290 for DC, $882 for SC and $883 for FFV. The cost per DALY averted was $641 for DC, $434 for SC and $563 for FFV without discounting or age weighting. These interventions are highly cost-effective by international thresholds. While it is debatable whether these resource requirements represent a feasible or sustainable investment given low health expenditures in Pakistan, these findings may provide justification for continuing Pakistan's investment in national social safety

    Research addressing value in healthcare requires a measure of cost. While there are many sources and types of cost data, each has strengths and weaknesses. Many researchers appear to create study-specific cost datasets, but the explanations of their costing methodologies are not always clear, causing their results to be difficult to interpret. Our solution, described in this paper, was to use widely accepted costing methodologies to create a service-level, standardized healthcare cost data warehouse from an institutional perspective that includes all professional and hospital-billed services for our patients. The warehouse is based on a National Institutes of Research-funded research infrastructure containing the linked health records and medical care administrative data of two healthcare providers and their affiliated hospitals. Since all patients are identified in the data warehouse, their costs can be linked to other systems and databases, such as electronic health records, tumor registries, and disease or treatment registries. We describe the two institutions' administrative source data; the reference files, which include Medicare fee schedules and cost reports; the process of creating standardized costs; and the warehouse structure. The costing algorithm can create inflation-adjusted standardized costs at the service line level for defined study cohorts on request. The resulting standardized costs contained in the data warehouse can be used to create detailed, bottom-up analyses of professional and facility costs of procedures, medical conditions, and patient care cycles without revealing business-sensitive information. After its creation, a standardized cost data warehouse is relatively easy to maintain and can be expanded to include data from other providers. Individual investigators who may not have sufficient knowledge about administrative data do not have to try to create their own standardized costs on a project-by-project basis because our data

    Recent studies examined the overall cost of pediatric stroke, but there are little data regarding the sources of these costs. We examined an administrative database that collected charges from 24 US children's hospitals to determine the sources of costs for acute hospital care of stroke. We used International Classification of Diseases, 9th Revision codes to search the Pediatric Health Information System. From 2003 to 2009 there were 1667 patients who had a primary diagnosis of stroke, 703 of which were hemorrhagic and 964 were ischemic. Individual costs, excluding physician charges, were gathered under 7 categories that were ranked to determine which contributed the most to total cost. Individual costs were ranked within their categories. We analyzed costs based on stroke type. Total costs were adjusted using the US Consumer Price Index to compare increases with the rate of inflation. Median total cost for any stroke was $19,548 (interquartile range, $10,764-$40,721). The category "other/nursing" contributed the most to hospital costs followed by imaging, laboratory, and pharmacy. Brain MRI and CT contributed the most to imaging costs. Hemorrhagic strokes (median $24,843) were more expensive than ischemic strokes (median $16,954). Total cost increased from 2003 to 2009, but no overall annual trend emerged after controlling for gender, age, race, and hospital. This is the first in-depth analysis of cost for pediatric stroke care. The highest cost categories are potential targets for cost containment but are also crucial for effective diagnosis and treatment. Necessary yet prudent use of imaging technologies and inpatient stays may be strategies for cost containment.

    The objective of this study is to identify the annual cost per capita by gender in first level of attention. It is a cost study in Family Physician Units in Mexico. The information corresponded to the year of 2004 and the study divided in the use profile and cost attention. USE PROFILE OF SERVICES: it was studied 1,585 clinical registries of patients, use profile defined by average and attention reasons by department, gender and age group. COST ATTENTION: considered in American dollars it included fixed unit cost (departmentalization adjusted by productivity), variable unit cost (micro cost technical), department unite cost by type attention, and department unit cost by age and gender. The life expectancy was of 73 years for men and 78 for women. Three scenes were identified. The annual cost per capita is superior among woman [US$73.24 (IC 95% $11.38 - $197.49)] than in man [$ 53.11 (IC 95% 2.51 - 207.71)]. The conclusion found that in the first level of attention the cost per capita is greater in woman than in man.

    2016-10-01

    Ambient mechanical vibrations offer an attractive solution for powering the wireless sensor nodes of the emerging “Internet-of-Things”. However, the wide-ranging variability of the ambient vibration frequencies pose a significant challenge to the efficient transduction of vibration into usable electrical energy. This work reports the development of a MEMS electromagnetic vibration energy harvester where the resonance frequency of the oscillator can be adjusted or tuned to adapt to the ambient vibrational frequency. Micro-fabricated silicon spring and double layer planar micro-coils along with sintered NdFeB micro-magnets are used to construct the electromagnetic transduction mechanism. Furthermore, another NdFeB magnet is adjustably assembled to induce variable magnetic interaction with the transducing magnet, leading to significant change in the spring stiffness and resonance frequency. Finite element analysis and numerical simulations exhibit substantial frequency tuning range (25% of natural resonance frequency) by appropriate adjustment of the repulsive magnetic interaction between the tuning and transducing magnet pair. This demonstrated method of frequency adjustment or tuning have potential applications in other MEMS vibration energy harvesters and micromechanical oscillators.

  10. Frequency adjustable MEMS vibration energy harvester

    2016-01-01

    Ambient mechanical vibrations offer an attractive solution for powering the wireless sensor nodes of the emerging “Internet-of-Things”. However, the wide-ranging variability of the ambient vibration frequencies pose a significant challenge to the efficient transduction of vibration into usable electrical energy. This work reports the development of a MEMS electromagnetic vibration energy harvester where the resonance frequency of the oscillator can be adjusted or tuned to adapt to the ambient vibrational frequency. Micro-fabricated silicon spring and double layer planar micro-coils along with sintered NdFeB micro-magnets are used to construct the electromagnetic transduction mechanism. Furthermore, another NdFeB magnet is adjustably assembled to induce variable magnetic interaction with the transducing magnet, leading to significant change in the spring stiffness and resonance frequency. Finite element analysis and numerical simulations exhibit substantial frequency tuning range (25% of natural resonance frequency) by appropriate adjustment of the repulsive magnetic interaction between the tuning and transducing magnet pair. This demonstrated method of frequency adjustment or tuning have potential applications in other MEMS vibration energy harvesters and micromechanical oscillators. (paper)

  15. Should adjustment disorder be conceptualized as transitional disorder? In pursuit of adjustment disorders definition.

    2012-12-01

    The DSM classification of an adjustment disorder is frequently criticized for not being well differentiated from other disorders. A possible reason for this is the vague definition of the term adjustment in social science literature. Hence, the current paper discusses the definition of adjustment and its implications for understanding maladjustment. Differential definitions of the terms adjustment, adaptation, socialization and coping are outlined, leading to the proposition that each one of them represents a different type of demand that is imposed on an individual who encounters a transitional event. Moreover, the four types of demands might be the possible sources of maladjustment. Helping people in transition requires an identification of the source, or combination of sources, that have led to the adjustment problem first, followed by the implementation of an adequate helping approach.

    An electric motor drive unit, particularly an adjustment drive for vehicles with at least two parallel drive shafts is described, which is compact and saves space, and whose manufacturing costs are low compared with those of well-known drive units of this type. The drive unit contains a suitable number of magnet systems, preferably permanent magnet systems, whose pole axes are spaced and run parallel. The two pole magnet systems have diametrically opposite shell-shaped segments, to which the poles are fixed. In at least one magnet system the two segments are connected by diametrically opposite flat walls parallel to the pole axes to form a single magnetic circuit pole housing. The segments of at least one other magnet system are arranged on this pole housing so that one of these flat walls is a magnetically conducting, connecting component of the magnetic circuit of the other magnet system.

  18. Risk Selection, Risk Adjustment and Choice: Concepts and Lessons from the Americas

    Ellis, Randall P.; Fernandez, Juan Gabriel

    2013-01-01

    Interest has grown worldwide in risk adjustment and risk sharing due to their potential to contain costs, improve fairness, and reduce selection problems in health care markets. Significant steps have been made in the empirical development of risk adjustment models, and in the theoretical foundations of risk adjustment and risk sharing. This literature has often modeled the effects of risk adjustment without highlighting the institutional setting, regulations, and diverse selection problems that risk adjustment is intended to fix. Perhaps because of this, the existing literature and their recommendations for optimal risk adjustment or optimal payment systems are sometimes confusing. In this paper, we present a unified way of thinking about the organizational structure of health care systems, which enables us to focus on two key dimensions of markets that have received less attention: what choices are available that may lead to selection problems, and what financial or regulatory tools other than risk adjustment are used to influence these choices. We specifically examine the health care systems, choices, and problems in four countries: the US, Canada, Chile, and Colombia, and examine the relationship between selection-related efficiency and fairness problems and the choices that are allowed in each country, and discuss recent regulatory reforms that affect choices and selection problems. In this sample, countries and insurance programs with more choices have more selection problems. PMID:24284351

  19. The influence of psychosocial factors in veteran adjustment to civilian life.

    Although most veterans have a successful transition to civilian life when they leave the military, some struggle to cope and adjust to the demands and challenges of civilian life. This study explores how a variety of psychosocial factors influence veteran adjustment to civilian life in Scotland, UK, and which of these factors predict a poor adjustment. One hundred and fifty-four veterans across Scotland completed a set of questionnaires that measured veteran adjustment difficulty, quality of life, mental health, stigma, self-stigma, attitude towards help-seeking, likelihood of help-seeking, experiential avoidance, reappraisal and suppression. Veteran adjustment difficulty and quality of life were significantly correlated to a number of psychosocial factors. Mental health, experiential avoidance and cognitive reappraisal were found to be predictors of veteran adjustment difficulty, and experiential avoidance and cognitive reappraisal partially mediated the relationship between mental health and veteran adjustment, with experiential avoidance being the stronger mediator. Our findings suggest that early assessment of experiential avoidance and cognitive reappraisal and the provision of relevant emotion regulation skills training could potentially reduce the veteran's need for more complex (and costly) psychological interventions in the future. Implications for veterans, as well as the services and professionals involved with veteran transition and health care are discussed. Copyright © 2018 John Wiley & Sons, Ltd.
