The result showed that there are institutions that issued higher cost compared with the others in producing the same learning media.展开更多
Three data envelopment analysis (DEA) models were used to analyse the relative efficiencies of four AIDS treatments in AIDS Clinical Trial Group (ACTG) Study 193A(1 309 patients in total, classified into 4 age groups)...Three data envelopment analysis (DEA) models were used to analyse the relative efficiencies of four AIDS treatments in AIDS Clinical Trial Group (ACTG) Study 193A(1 309 patients in total, classified into 4 age groups). Results from the output-oriented BCC model show that Treatment 4 ( 600 mg of zidovudine plus 400 mg of didanosine plus 400 mg of nevirapine) is particularly efficient for age group 14—25, but not efficient for the older age groups; Treatment 1 (600 mg of zidovudine alternating monthly with 400 mg of didanosine)and Treatment 2 (600 mg of zidovudine plus 2.25 mg of zalcitabine) are efficient for the age groups 35—45 and 45— ; age group 25—35 does not have a particularly efficient treatment, but Treatments 1 and 2 are relatively good. The cost efficiency BCC model, which takes the treatment cost into account, gives similar results as the output-oriented model. Results from the indirect output-oriented BCC model, which allows the replacement among medicines, show that the efficiency of Treatment 2 has greatly decreased compared with that of the output-oriented model, and a set of optimal medicine amounts for different age groups is obtained.展开更多

Considering the costs of emission reduction, supervision and penalty, we went all out to analyze the optimal decision of cost efficiency of regulators when implementing these three policy instruments: carbon emission standards, carbon emission trading permissions, and carbon taxes as well. Its result has indicated: In strict accordance with control target of total carbon emissions, regulators are willing to render social and economic cost able to achieve the goal of optimal cost efficiency by regulating carbon emission standards and supervising marginal cost caused by variations in the probability; fortunately, under the conditions of low supervisory cost and certain criteria which is met, the implementation of carbon emission trading permissions could provide social and economic cost with opportunities to realize that objective; through comparative analysis, carbon emission trading permissions have the advantages of higher efficiency than carbon emission standards on the premise of incomplete information. During the implementation of carbon taxes strategy, when there exists uncertainty information in the enterprises reduction behaviors, the condition which enterprises can fully comply with is the tax rate level is not higher than marginal penalty function; the tax rate level of enterprises perfect compliance ought not to be lower than the division of marginal penalty cost and marginal supervisory cost. The optimal strategy of enterprises imperfect compliance is that regulators varying the marginal cost of emission standards is equal to varying that of supervisory probability.展开更多

The results indicate that policy variables, such as the reserve requirement ratio, the interest rate spread and open market operations by the People＇s Bank of China, are effective in improving the cost efficiency of banks, but shadow banking variables may reduce cost efficiency. Among the various bank types, city commercial banks appear to be the most efficient and foreign banks are the least efficient. The present study suggests that policy-makers can have a positive influence on bank cost efficiency by adjusting macro policy variables on different types of banks and by requiring more information on the shadow banking activities to improve monitoring.展开更多

The study assessed the components of system losses within the ECG by determining and computing the percentage of system losses within ECG, examining the causes of both commercial and technical losses in ECG, and determining ways to improve energy efficiency by reducing system losses in the most cost-efficient manner. The study adopted deductive reasoning and a quantitative approach to guide data collection and analysis of the research output. A sample of 345 technical and non-technical staff of ECG in the Greater Accra Metropolis was selected from a population of 2500. Purposive, simple random, and cluster sampling techniques were used in identifying and accessing respondents for the study. Descriptive statistics were applied to measure central tendency and degrees of dispersion and the Relative Importance Index (RII) to predict criterion and predictor variables. The impact of low voltage network losses can adversely contribute to technical losses (20%) and reduce energy efficiency in power or electricity distribution companies. Non-technical losses are mainly caused by illegal connections, meter problems, and billing problems. Each of the non-technical losses contributes a maximum of 10% to system losses. Contributors to system losses at ECG are ranked first for power theft and least for lack of incentives. System losses at ECG include metering inaccuracies, bad workmanship, unmetered supply, and lengthy distribution lines, each recording a mean value of above 3.5. Measures to improve monitoring of the networks and systems at ECG and discourage power theft should include an extensive quantification, patrolling, and inspection of the entire network to assess the extent of the network and conditions relevant for the placement of systematically planned maintenance programmes.展开更多

We tried to answer the question that whether lower length of stay and higher utilization of post-op facilities would be helpful to control the overall costs. Using the National Hospital Discharge Survey (NHDS) database and cost data from Blue Cross Blue shield, this study seeks to identify which U.S. region renders the highest quality patient care during a three-year span of 2008-2010. Using length of stay and discharge disposition (2010) as input factors, and regional TKA costs (2013) as output factors, Data Envelopment Analysis (DEA), a non-parametric method, illustrated the efficiency ranking of four regions in the US on TKA expenditures. The result shows the West is the most efficient region on controlling the overall cost by shrinking the length of stay and increasing the utilization of short-term/long-term care facilities.展开更多

The delay of maintenance works can lead the road in the stage of expensive rehabilitation and reconstruction. In Nepal, Department of Roads (DoR) is responsible for maintenance of strategic roads of country. The maintenance practice of the road under Department of Road is predominantly based on Strengthen Maintenance Division Process where several maintenance activities like Routine maintenance, Recurrent Maintenance, Periodic Maintenance and Emergency Maintenance are planned and carried out. The maintenance work is based on traditional quantity and unit price based short term maintenance contracts, where maintenance of physical works is outsourced. Client demands the contractor what work is to be done, when to be do it and the extent of the work. The contractor is paid on the basis of a defined output or quantity accomplished, and the schedule of the rates. DoR engineers required full time supervision of work. Pilot based performance based maintenance practice of road started in Nepal in 2003. The study assesses performance road maintenance practices of road maintenance in Nepal on the basis of the framework of cost efficiency, level of service effectiveness and quality of service. The study concluded that implementation of Performance Based Maintenance Contract (PBMC) was not successful in Nepal as Road Asset condition was not maintained to performance standard. One of the reasons is the weak service delivery of contractor alongside weak contract enforcement from the road agency.展开更多

Results from the output-oriented BCC model show that Treatment 4 ( 600 mg of zidovudine plus 400 mg of didanosine plus 400 mg of nevirapine) is particularly efficient for age group 14—25, but not efficient for the older age groups; Treatment 1 (600 mg of zidovudine alternating monthly with 400 mg of didanosine)and Treatment 2 (600 mg of zidovudine plus 2.25 mg of zalcitabine) are efficient for the age groups 35—45 and 45— ; age group 25—35 does not have a particularly efficient treatment, but Treatments 1 and 2 are relatively good. The cost efficiency BCC model, which takes the treatment cost into account, gives similar results as the output-oriented model. Results from the indirect output-oriented BCC model, which allows the replacement among medicines, show that the efficiency of Treatment 2 has greatly decreased compared with that of the output-oriented model, and a set of optimal medicine amounts for different age groups is obtained.

文摘This study uses stochastic frontier analysis to examine the factors that influenced cost efficiency of banks in China from 2005 to 2013. The results indicate that policy variables, such as the reserve requirement ratio, the interest rate spread and open market operations by the People＇s Bank of China, are effective in improving the cost efficiency of banks, but shadow banking variables may reduce cost efficiency. Among the various bank types, city commercial banks appear to be the most efficient and foreign banks are the least efficient. The present study suggests that policy-makers can have a positive influence on bank cost efficiency by adjusting macro policy variables on different types of banks and by requiring more information on the shadow banking activities to improve monitoring.

文摘Most of the electric arc furnace(EAF) dedusting systems installed worldwide have been designed and built with the mere intention to comply with certain environmental regulations and limiting values for a determined process and production capacity- and this usually works as long as those variables are fix.But reality shows thatever since the recent financial crisis- steel producers are perpetually forced to adapt their steelmaking process in order to meet the requirements of the market and properly react to its fluctuations(e.g.by flexible use of input materials).Many installed dedusting systems cannot live up to this challenge.Badische Stahl-Engineering GmbH (BSE) optimizes dedusting systems to meet various process requirements and thus increase the overall productivity and cost efficiency- along with the strict compliance with all environmental standards and local legislations.This paper further describes the basic considerations to be taken and the BSE approach to deal with these challenges, emphasizing it by examples of our latest projects world wide.
文摘This paper examined the relationship between farm characteristics and perceived sources of competitive advantage,and cost-based and revenue-based efficiency indices.Gross farm income and the percentage of labor devoted to crop production were significant and positively correlated with cost and revenue efficiency,while the perception of the cowherd being the most important part of the operation was negatively correlated with efficiency.In general,perceived sources of competitive advantage were not significantly correlated with cost or revenue efficiency.
文摘To reform the unit of preventive medicine in Orleans metropole, the Director of the Administration decided to co-sign an agreement to optimize the organization of a common preventive medicine service: we made a deliberation model to permit for others towns which wanted to join us. The cost evaluated to reach the service was the cost for medical examination, regardless of the professional which included staff costs and operating costs (social benefits, costs of supplies and materials, training costs). A statement of the tasks performed for the beneficiary community was kept daily by the SMP. A strong will of the Metropolis and municipalities is to develop a synergy around health and safety at work. A joint Metropolis of Orleans, an organization chart since 1/2/2016 integrates the preventive medicine service within a Quality of Life at Work service: a multi-disciplinary service composed of prevention specialists, social workers, responsible for social action and SMP, a Department of Preventive Medicine was developed and itself multidisciplinary in accordance with the law of July 20, 2011: including doctors, nurses, psychologists, sophrologist, and a dietician. A new and active network of health is now operant with specialist correspondents. An audit is programmed in April 2018 to assess the efficacy of this network.
文摘Roads are the major asset of any country and to conserve them maintenance is essential. The delay of maintenance works can lead the road in the stage of expensive rehabilitation and reconstruction. In Nepal, Department of Roads (DoR) is responsible for maintenance of strategic roads of country. The maintenance practice of the road under Department of Road is predominantly based on Strengthen Maintenance Division Process where several maintenance activities like Routine maintenance, Recurrent Maintenance, Periodic Maintenance and Emergency Maintenance are planned and carried out. The maintenance work is based on traditional quantity and unit price based short term maintenance contracts, where maintenance of physical works is outsourced. Client demands the contractor what work is to be done, when to be do it and the extent of the work. The contractor is paid on the basis of a defined output or quantity accomplished, and the schedule of the rates. DoR engineers required full time supervision of work. Pilot based performance based maintenance practice of road started in Nepal in 2003. The study assesses performance road maintenance practices of road maintenance in Nepal on the basis of the framework of cost efficiency, level of service effectiveness and quality of service. The study concluded that implementation of Performance Based Maintenance Contract (PBMC) was not successful in Nepal as Road Asset condition was not maintained to performance standard. One of the reasons is the weak service delivery of contractor alongside weak contract enforcement from the road agency.
