  1. 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...

    Even though there's been a slight reprieve in energy costs, the reality is that the cost of non-renewable energy is increasing, and state education budgets are shrinking. One way to keep energy and operations costs from overshadowing education budgets is to develop a 10-year energy audit plan to eliminate waste. First, facility managers should…

  6. Minimizing Costs Can Be Costly

    Directory of Open Access Journals (Sweden)

    Rasmus Rasmussen

    2010-01-01

    Full Text Available A quite common practice, even in academic literature, is to simplify a decision problem and model it as a cost-minimizing problem. In fact, some type of models has been standardized to minimization problems, like Quadratic Assignment Problems (QAPs, where a maximization formulation would be treated as a “generalized” QAP and not solvable by many of the specially designed softwares for QAP. Ignoring revenues when modeling a decision problem works only if costs can be separated from the decisions influencing revenues. More often than we think this is not the case, and minimizing costs will not lead to maximized profit. This will be demonstrated using spreadsheets to solve a small example. The example is also used to demonstrate other pitfalls in network models: the inability to generally balance the problem or allocate costs in advance, and the tendency to anticipate a specific type of solution and thereby make constraints too limiting when formulating the problem.

  10. COST MEASUREMENT AND COST MANAGEMENT IN TARGET COSTING

    2012-07-01

    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

  11. The Quality Costs

    2005-10-01

    Full Text Available Quality has a cost and this fact cannot be denied. In the same time, it is true that non-quality is more expensive. Quality is considered asbeing expensive because no one tries to calculate non-quality costs. Out of the final cost of a product, non-quality stands for 20% up to 35%.According to this idea all the economic sectors contain error costs caused by the mistakes made during the production process. To have a realconsummation situation, it is necessary to know the cost quantum. The final quality cost is the result of the following costs: prevention costs,necessary to preclude errors; evaluation costs, as results of a final product evaluation, and failure costs, generated by the non – attainment ofproduct’s purpose. The gross of these costs stand for the total quality costs. Nowadays, the problem inheres in how much this quality cost representsout of the final cost.

    2003-01-01

    Understanding how quality improvement affects costs is important. Unfortunately, low-cost, reliable ways of measuring direct costs are scarce. This article builds on the principles of process improvement to develop a costing strategy that meets both criteria. Process-based costing has 4 steps: developing a flowchart, estimating resource use, valuing resources, and calculating direct costs. To illustrate the technique, this article uses it to cost the care planning process in 3 long-term care facilities. We conclude that process-based costing is easy to implement; generates reliable, valid data; and allows nursing managers to assess the costs of new or modified processes.

    2016-05-01

    This paper presents a methodology for a heliostat cost optimization study. First different variants of small, medium sized and large heliostats are designed. Then the respective costs, tracking and optical quality are determined. For the calculation of optical quality a structural model of the heliostat is programmed and analyzed using finite element software. The costs are determined based on inquiries and from experience with similar structures. Eventually the levelised electricity costs for a reference power tower plant are calculated. Before each annual simulation run the heliostat field is optimized. Calculated LCOEs are then used to identify the most suitable option(s). Finally, the conclusions and findings of this extensive cost study are used to define the concept of a new cost-efficient heliostat called `Stellio'.

  20. Avoidable waste management costs

    Energy Technology Data Exchange (ETDEWEB)

    Hsu, K.; Burns, M.; Priebe, S.; Robinson, P.

    1995-01-01

    This report describes the activity based costing method used to acquire variable (volume dependent or avoidable) waste management cost data for routine operations at Department of Energy (DOE) facilities. Waste volumes from environmental restoration, facility stabilization activities, and legacy waste were specifically excluded from this effort. A core team consisting of Idaho National Engineering Laboratory, Los Alamos National Laboratory, Rocky Flats Environmental Technology Site, and Oak Ridge Reservation developed and piloted the methodology, which can be used to determine avoidable waste management costs. The method developed to gather information was based on activity based costing, which is a common industrial engineering technique. Sites submitted separate flow diagrams that showed the progression of work from activity to activity for each waste type or treatability group. Each activity on a flow diagram was described in a narrative, which detailed the scope of the activity. Labor and material costs based on a unit quantity of waste being processed were then summed to generate a total cost for that flow diagram. Cross-complex values were calculated by determining a weighted average for each waste type or treatability group based on the volume generated. This study will provide DOE and contractors with a better understanding of waste management processes and their associated costs. Other potential benefits include providing cost data for sites to perform consistent cost/benefit analysis of waste minimization and pollution prevention (WMIN/PP) options identified during pollution prevention opportunity assessments and providing a means for prioritizing and allocating limited resources for WMIN/PP.

    Gonzalez-Sanchez, M Beatriz; Lopez-Valeiras, Ernesto; Morente, Manuel M; Fernández Lago, Orlando

    2013-10-01

    Current economic conditions and budget constraints in publicly funded biomedical research have brought about a renewed interest in analyzing the cost and economic viability of research infrastructures. However, there are no proposals for specific cost accounting models for these types of organizations in the international scientific literature. The aim of this paper is to present the basis of a cost analysis model useful for any biobank regardless of the human biological samples that it stores for biomedical research. The development of a unique cost model for biobanks can be a complicated task due to the diversity of the biological samples they store. Different types of samples (DNA, tumor tissues, blood, serum, etc.) require different production processes. Nonetheless, the common basic steps of the production process can be identified. Thus, the costs incurred in each step can be analyzed in detail to provide cost information. Six stages and four cost objects were obtained by taking the production processes of biobanks belonging to the Spanish National Biobank Network as a starting point. Templates and examples are provided to help managers to identify and classify the costs involved in their own biobanks to implement the model. The application of this methodology will provide accurate information on cost objects, along with useful information to give an economic value to the stored samples, to analyze the efficiency of the production process and to evaluate the viability of some sample collections.

    There are many costs associated with parenteral nutrition: physician time, nursing time, biochemical monitoring, patient education, ancillary equipment and the nutrition solutions themselves. The solutions are easily identified as responsible for a large proportion of these costs. There are several strategies that can be used to help control pharmacy costs, such as selection of ingredients, purchasing contracts, standardized formulae and prescribing procedures, preprinted doctor's order forms, automated manufacturing and labelling processes, patient monitoring, all-in-one preparation, and contracted manufacturing services. Individual pharmacies need to know what options are available in order to select those that, in the context of their own institutions, can lead to cost savings and improved efficiency.

    In the 199os, Hewlett-Packard's PC business was struggling to turn a dollar, despite the company's success in winning market share. By 1997, margins on its PCs were as thin as a silicon wafer, and some product lines hadn't turned a profit since 1993. The problem had everything to do with the PC industry's notoriously short product cycles and brutal product and component price deflation. A common rule of thumb was that the value of a fully assembled PC decreased 1% a week. In such an environment, inventory costs become critical. But not just the inventory costs companies traditionally track, HP found, after a thorough review of the problem. The standard "holding cost of inventory"--the capital and physical costs of inventory--accounted for only about 10% of HP's inventory costs. The greater risks, it turned out, resided in four other, essentially hidden costs, which stemmed from mismatches between demand and supply: Component devaluation costs for components still held in production; Price protection costs incurred when product prices drop on the goods distributors still have on their shelves; Product return costs that have to be absorbed when distributors return and receive refunds on overstock items, and; Obsolescence costs for products still unsold when new models are introduced. By developing metrics to track those costs in a consistent way throughout the PC division, HP has found it can manage its supply chains with much more sophistication. Gone are the days of across-the-board measures such as,"Everyone must cut inventories by 20% by the end of the year," which usually resulted in a flurry of cookie-cutter lean production and just-in-time initiatives. Now, each product group is free to choose the supply chain configuration that best suits its needs. Other companies can follow HP's example.

    BACKGROUND: To estimate the direct and indirect costs of stroke in patients and their partners. DESCRIPTION: Direct and indirect costs were calculated using records from the Danish National Patient Registry from 93,047 ischemic, 26,012 hemorrhagic and 128,824 unspecified stroke patients...... and compared with 364,433, 103,741 and 500,490 matched controls, respectively. RESULTS: Independent of age and gender, stroke patients had significantly higher rates of mortality, health-related contacts, medication use and lower employment, lower income and higher social-transfer payments than controls....... The attributable cost of direct net health care costs after the stroke (general practitioner services, hospital services, and medication) and indirect costs (loss of labor market income) were €10,720, €8,205 and €7,377 for patients, and €989, €1,544 and €1.645 for their partners, over and above that of controls...

    Based on the well-known fact that social networks can provide effective mechanisms that help to increase the trust level between two trade partners, we apply a simple game-theoretical framework to derive transaction costs as a high risk of opportunistic behavior in a repeated trade relation...... transaction cost functions for all traded farm inputs and outputs. Estimation results based on a sample of 315 Polish farms imply a significant influence of social network structures on farm’s transaction costs. Moreover, estimated transaction costs correspond to a reasonable amount of farm specific shadow...... determined by the density and size of trading networks. In the empirical part of the paper we apply a two stage procedure to estimate the impact of social network structures on farm’s transaction costs observed for different input and output markets. At a first stage we estimate a multiple input...

  18. Analyzing EUV mask costs

    Science.gov (United States)

    Lercel, Michael; Kasprowicz, Bryan

    2016-10-01

    The introduction of Extreme Ultraviolet Lithography (EUV) as a replacement for multiple patterning is based on improvements of cycle time, yield, and cost. Earlier cost studies have assumed a simple assumption that EUV masks (being more complex with the multilayer coated blank) are not more than three times as expensive as advanced ArFi (ArF immersion) masks. EUV masks are expected to be more expensive during the ramp of the technology because of the added cost of the complex mask blank, the use of EUV specific mask tools, and a ramp of yield learning relative to the more mature technologies. This study concludes that, within a range of scenarios, the hypothesis that EUV mask costs are not more than three times that of advanced ArFi masks is valid and conservative.

  19. Biosimilar Insulin and Costs

    Science.gov (United States)

    Heinemann, Lutz

    2015-01-01

    The costs for insulin treatment are high, and the steady increase in the number of patients with diabetes on insulin presents a true challenge to health care systems. Therefore, all measures to lower these costs are welcomed by patients, physicians, and health care providers. The market introduction of biosimilar insulins presents an option to lower treatment costs as biosimilars are usually offered at a lower price than the originator product. However, the assumption that a drastic reduction in insulin prices will take place, as was observed with many generic drugs, is most probably not realistic. As the first biosimilar insulin has now been approved in the EU, this commentary discusses a number of aspects that are relevant when it comes to the potential cost reduction we will see with the use of biosimilar insulins.

  2. [Costs of hand emergencies].

    Science.gov (United States)

    Raimbeau, G

    2003-10-01

    In France at the present time, there is no comprehensive registry of hand injuries. Three types of occurrences; motor vehicle accidents, work accidents, and accidents incident to activities of daily living, are covered by different types of insurance. It is the individual insurance companies, payers of the indemnification, who maintain registries of these accidents. Statistics on work accidents are very detailed and consistent, but they are oriented toward risk management. The aggregate cost of traumatic injuries to the hand is not known. Only large financial institutions are equipped to determine appropriate preventive measures and to establish premium rates based on loss experience. In 2001, hand injuries accounted for 27% of work accidents causing loss of work of at least 1 day. About 29.8% of these work accidents caused permanent partial impairment. About 17.7% of total days lost and 18.2% of the total costs of permanent impairment were due to hand injuries. In the system of compensation for work accidents, there is a major difference in the cost according to the severity of the impairment. If the permanent impairment is equal to or less than 9%, a lump sum payment is made, but if the permanent impairment is over 9%, the worker receives regular payments for the rest of his life. In 2000, the average cost of a work injury with partial permanent impairment of over 9% was [symbol: see text] 85,405, while the average cost of a lump sum settlement was only [symbol: see text] 1479, a ratio of 57 to 1. The compensation costs represent 80% of the cost of work accidents, while the cost of treatment, including all providers and institutions, makes up only 20% of the cost. Compensation for sequelae of accidents in the course of daily life is new for the insurance companies, although these accidents are frequent and often cause significant repercussions in the professional lives of victims because of the loss of hand function. Provision of optimal treatment for these

  4. Sanitary costs of osteoarthritis

    Directory of Open Access Journals (Sweden)

    M. Franceschini

    2011-09-01

    Full Text Available Muscoloskeletal disorders are the first cause of disability and the second cause of permanent disablement in Italy. Osteoarthritis is the most frequent rheumatic disease and affects about 4 million Italians. In spite of that, data concerning social costs are lacking. On account of this lack we measured sanitary costs of 314 patients suffering from osteoarthritis. A retrospective, prevalence- based multicentric study was performed using a bottom-up approach. The study period was 12 months and referred to 1999. Eight percent of patients didn’t take any drug for the treatment of osteoarthritis; NSAIDs were prescribed to 86.9% of patients, analgesics to 29.9%, chondroprotective drugs to 7.6%, and gastroprotective drugs to 36.9%. Total sanitary costs came to 455 € / patient / year: 122 € were spent on diagnostics, 293 € on therapy and 40 € on management of drug-related gastropathy. Since the costs of anti-inflammatory drugs came to 30 € we calculated iatrogenic cost factor of 2.3. Moreover, the study supplied interesting informations about prescriptive habits, which differ in Italy from international guidelines for the medical treatment of OA, about patient management, because of hospitalization, which by itself absorbs 1/3 of resources, and about physiotherapy, which costs twice as much as pharmacological therapy. At last, data analysis gave the cue for suggestions on changing patients’ management.

  5. How much does curation cost?

    Science.gov (United States)

    Karp, Peter D

    2016-01-01

    NIH administrators have recently expressed concerns about the cost of curation for biological databases. However, they did not articulate the exact costs of curation. Here we calculate the cost of biocuration of articles for the EcoCyc database as $219 per article over a 5-year period. That cost is 6-15% of the cost of open-access publication fees for publishing biomedical articles, and we estimate that cost is 0.088% of the cost of the overall research project that generated the experimental results. Thus, curation costs are small in an absolute sense, and represent a miniscule fraction of the cost of the research.

    This paper empirically decomposes the costs of welfare participation using a model of labor supply and participation in multiple welfare programs. Prior estimates of the cost of welfare participation have not differentiated psychological costs, or stigma, from the effort required to become eligible and maintain eligibility (time costs). The relative size of these two costs has implications for policy. We find that psychological costs are at least as large as the time costs associated with par...

  11. Underestimation of Project Costs

    Science.gov (United States)

    Jones, Harry W.

    2015-01-01

    Large projects almost always exceed their budgets. Estimating cost is difficult and estimated costs are usually too low. Three different reasons are suggested: bad luck, overoptimism, and deliberate underestimation. Project management can usually point to project difficulty and complexity, technical uncertainty, stakeholder conflicts, scope changes, unforeseen events, and other not really unpredictable bad luck. Project planning is usually over-optimistic, so the likelihood and impact of bad luck is systematically underestimated. Project plans reflect optimism and hope for success in a supposedly unique new effort rather than rational expectations based on historical data. Past project problems are claimed to be irrelevant because "This time it's different." Some bad luck is inevitable and reasonable optimism is understandable, but deliberate deception must be condemned. In a competitive environment, project planners and advocates often deliberately underestimate costs to help gain project approval and funding. Project benefits, cost savings, and probability of success are exaggerated and key risks ignored. Project advocates have incentives to distort information and conceal difficulties from project approvers. One naively suggested cure is more openness, honesty, and group adherence to shared overall goals. A more realistic alternative is threatening overrun projects with cancellation. Neither approach seems to solve the problem. A better method to avoid the delusions of over-optimism and the deceptions of biased advocacy is to base the project cost estimate on the actual costs of a large group of similar projects. Over optimism and deception can continue beyond the planning phase and into project execution. Hard milestones based on verified tests and demonstrations can provide a reality check.

    2010-12-17

    Seal durability is critical to achieving the 2010 DOE operational life goals for both stationary and transportation PEM fuel cell stacks. The seal material must be chemically and mechanically stable in an environment consisting of aggressive operating temperatures, humidified gases, and acidic membranes. The seal must also be producible at low cost. Currentlyused seal materials do not meet all these requirements. This project developed and demonstrated a high consistency hydrocarbon rubber seal material that was able to meet the DOE technical and cost targets. Significant emphasis was placed on characterization of the material and full scale molding demonstrations.

    Power towers are capable of producing solar-generated electricity and hydrogen on a large scale. Heliostats are the most important cost element of a solar power tower plant. Since they constitute {approx} 50% of the capital cost of the plant it is important to reduce heliostat cost as much as possible to improve the economic performance of power towers. In this study we evaluate current heliostat technology and estimate a price of $126/m{sup 2} given year-2006 materials and labor costs for a deployment of {approx}600 MW of power towers per year. This 2006 price yields electricity at $0.067/kWh and hydrogen at $3.20/kg. We propose research and development that should ultimately lead to a price as low as $90/m{sup 2}, which equates to $0.056/kWh and $2.75/kg H{sup 2}. Approximately 30 heliostat and manufacturing experts from the United States, Europe, and Australia contributed to the content of this report during two separate workshops conducted at the National Solar Thermal Test Facility.

    2003-04-01

    Healthcare organizations can achieve revenue-cycle improvement while maintaining optimum staffing levels by taking a three-step approach-developing a plan, measuring costs, and using benchmarks to measure performance. Planned cost reductions can be achieved without a negative impact on the organization. Cost-reduction strategies should look at purchased services, staffing, and the cost-to-collect ratio. Healthcare organizations should reach target performance levels before implementing a cost-reduction strategy.

    A cost-based approach to asset-pricing equilibrium relationships is developed. A cost function induces a stochastic discount factor (pricing kernel) that is a function of random output, prices, and capital stockt. By eliminating opportunities for arbitrage between financial markets and the production technology, firms minimize the current cost of future consumption. The first-order conditions for this cost minimization problem generate the stochastic discount factor. The cost-based approach i...

  17. The Yale Cost Model and cost centres: servant or master?

    Science.gov (United States)

    Rigby, E

    1993-01-01

    Cost accounting describes that aspect of accounting which collects, allocates and controls the cost of producing a service. Costing information is primarily reported to management to enable control of costs and to ensure the financial viability of units, departments and divisions. As costing studies continue to produce estimates of Diagnosis Related Group (DRG) costs in New South Wales hospitals, as well as in other states, costs for different hospitals are being externally compared, using a tool which is usually related to internal management and reporting. Comparability of costs is assumed even though accounting systems differ. This paper examines the cost centre structures at five major teaching hospitals in Sydney. It describes the similarities and differences in how the cost centres were constituted, and then details the line items of expenditure that are charged to each cost centre. The results of a comparative study of a medical specialty are included as evidence of different costing methodologies in the hospitals. The picture that emerged from the study is that the hospitals are constituting their cost centres to meet their internal management needs, that is, to know the cost of running a ward or nursing unit, a medical specialty, department and so on. The rationale for the particular cost centre construction was that cost centre managers could manage and control costs and assign responsibility. There are variations in procedures for assigning costs to cost centres, and the question is asked 'Do these variations in procedures make a material difference to our ability to compare costs per Diagnosis Related Group at the various hospitals?' It is contended that the accounting information, which is produced as a result of different practices, is primarily for internal management, not external comparison. It would be better for hospitals to compare their estimated costs per Diagnosis Related Group to an internal standard cost rather than the costs from other

    Callahan, Hilary S; Maughan, Heather; Steiner, Uli

    2008-01-01

    Why are some traits constitutive and others inducible? The term costs often appears in work addressing this issue but may be ambiguously defined. This review distinguishes two conceptually distinct types of costs: phenotypic costs and plasticity costs. Phenotypic costs are assessed from patterns...... of covariation, typically between a focal trait and a separate trait relevant to fitness. Plasticity costs, separable from phenotypic costs, are gauged by comparing the fitness of genotypes with equivalent phenotypes within two environments but differing in plasticity and fitness. Subtleties associated with both...... types of costs are illustrated by a body of work addressing predator-induced plasticity. Such subtleties, and potential interplay between the two types of costs, have also been addressed, often in studies involving genetic model organisms. In some instances, investigators have pinpointed the mechanistic...

    Full Text Available Introduction. Cost of anaesthesiology represent defined measures to determine a precise profile of expenditure estimation of surgical treatment, which is important regarding planning of healthcare activities, prices and budget. Objective. In order to determine the actual value of anaestesiological services, we started with the analysis of activity based costing (ABC analysis. Methods. Retrospectively, in 2005 and 2006, we estimated the direct costs of anestesiological services (salaries, drugs, supplying materials and other: analyses and equipment. of the Institute of Anaesthesia and Resuscitation of the Clinical Centre of Serbia. The group included all anesthetized patients of both sexes and all ages. We compared direct costs with direct expenditure, “each cost object (service or unit” of the Republican Health-care Insurance. The Summary data of the Departments of Anaesthesia documented in the database of the Clinical Centre of Serbia. Numerical data were utilized and the numerical data were estimated and analyzed by computer programs Microsoft Office Excel 2003 and SPSS for Windows. We compared using the linear model of direct costs and unit costs of anaesthesiological services from the Costs List of the Republican Health-care Insurance. Results. Direct costs showed 40% of costs were spent on salaries, (32% on drugs and supplies, and 28% on other costs, such as analyses and equipment. The correlation of the direct costs of anaestesiological services showed a linear correlation with the unit costs of the Republican Healthcare Insurance. Conclusion. During surgery, costs of anaesthesia would increase by 10% the surgical treatment cost of patients. Regarding the actual costs of drugs and supplies, we do not see any possibility of costs reduction. Fixed elements of direct costs provide the possibility of rationalization of resources in anaesthesia.

  6. Popularity at Minimum Cost

    Kavitha, Telikepalli; Nimbhorkar, Prajakta

    2010-01-01

    We consider an extension of the {\\em popular matching} problem in this paper. The input to the popular matching problem is a bipartite graph G = (A U B,E), where A is a set of people, B is a set of items, and each person a belonging to A ranks a subset of items in an order of preference, with ties allowed. The popular matching problem seeks to compute a matching M* between people and items such that there is no matching M where more people are happier with M than with M*. Such a matching M* is called a popular matching. However, there are simple instances where no popular matching exists. Here we consider the following natural extension to the above problem: associated with each item b belonging to B is a non-negative price cost(b), that is, for any item b, new copies of b can be added to the input graph by paying an amount of cost(b) per copy. When G does not admit a popular matching, the problem is to "augment" G at minimum cost such that the new graph admits a popular matching. We show that this problem is...

    2012-10-01

    The current study examined costs experienced by victims of completed rape (n=49) and attempted sexual assault (n=91) using quantitative analyses of 13 domains: health, self-esteem, self-perceived attractiveness, self-perceived mate value, family relationships,work life, social life, social reputation, sexual reputation, desire to have sex, frequency of sex, enjoyment of sex, and long-term, committed relationships. Women also provided descriptive accounts of their experiences, and we used these to illustrate the costs in the victims' own words.Compared to victims of an attempted sexual assault, victims of a completed rape reported significantly more negative outcomes in 11 of the 13 domains. The most negatively affected domains were self-esteem, sexual reputation, frequency of sex, desire to have sex, and self-perceived mate value. Although victims of rape experienced more negative effects than victims of attempted sexual assault,both groups of victims reported negative effects in every domain.Discussion focuses on the implications of the differing degrees and patterns of the costs of attempted and completed sexual victimization.

    Determining the cost-effectiveness of healthcare interventions is key to the decision-making process in healthcare. Cost comparisons are used to demonstrate the economic value of treatment options, to evaluate the impact on the insurer budget, and are often used as a key criterion in treatment comparison and comparative effectiveness; however, little guidance is available to researchers for establishing the costing of clinical events and resource utilization. Different costing methods exist, and the choice of underlying assumptions appears to have a significant impact on the results of the costing analysis. This editorial describes the importance of the choice of the costing technique and it's potential impact on the relative cost of treatment options. This editorial also calls for a more efficient approach to healthcare intervention costing in order to ensure the use of consistent costing in the decision-making process.

    Successful commercialization of fusion energy requires economic viability as well as technical and scientific feasibility. To assess economic viability, we have conducted a pre-conceptual level evaluation of LIFE economics. Unit costs are estimated from a combination of bottom-up costs estimates, working with representative vendors, and scaled results from previous studies of fission and fusion plants. An integrated process model of a LIFE power plant was developed to integrate and optimize unit costs and calculate top level metrics such as cost of electricity and power plant capital cost. The scope of this activity was the entire power plant site. Separately, a development program to deliver the required specialized equipment has been assembled. Results show that LIFE power plant cost of electricity and plant capital cost compare favorably to estimates for new-build LWR's, coal and gas - particularly if indicative costs of carbon capture and sequestration are accounted for.

    2015-04-01

    Breaches in data security have become commonplace in health care, making IT security a necessary cost for healthcare organizations. Organizations that do not invest proactively in IT security face a significant risk of incurring much greater costs from incidents involving compromised data security. Direct costs of security breaches include the costs of discovery, response, investigation, and notification and also can include state or federal penalties and costs of compliance with corrective action plans and resolution agreements. Hidden costs can include damage to brand, loss of consumer confidence, reduced HCAHPS scores, and--by extension--reduced value-based purchasing payments.

    To date, there has been no standard method or tool to analyze the installed and operational costs for distributed wind turbine systems. This report describes the development of a classification system, or taxonomy, for distributed wind turbine project costs. The taxonomy establishes a framework to help collect, sort, and compare distributed wind cost data that mirrors how the industry categorizes information. The taxonomy organizes costs so they can be aggregated from installers, developers, vendors, and other sources without losing cost details. Developing a peer-reviewed taxonomy is valuable to industry stakeholders because a common understanding the details of distributed wind turbine costs and balance of station costs is a first step to identifying potential high-value cost reduction opportunities. Addressing cost reduction potential can help increase distributed wind's competitiveness and propel the U.S. distributed wind industry forward. The taxonomy can also be used to perform cost comparisons between technologies and track trends for distributed wind industry costs in the future. As an initial application and piloting of the taxonomy, preliminary cost data were collected for projects of different sizes and from different regions across the contiguous United States. Following the methods described in this report, these data are placed into the established cost categories.

    Full Text Available Solar energy the most efficient, eco-friendly and abundantly available energy source in the nature. It can be converted into electrical energy in cost effective manner. In recent years, the interest in solar energy has risen due to surging oil prices and environmental concern. In many remote or underdeveloped areas, direct access to an electric grid is impossible and a photovoltaic inverter system would make life much simpler and more convenient. With this in mind, it is aimed to design, build, and test a solar panel inverter. This inverter system could be used as backup power during outages, battery charging, or for typical household applications. The main components of this solar system are solar cell, dc to dc boost converters, and inverter. Sine wave push pull inverter topology is used for inverter. In this topology only two MOSFETs are used and isolation requirement between control circuit and power circuit is also less which helps to decrease the cost of solar inverter.

    Savage, G T; Campbell, K S; Patman, T; Nunnelley, L L

    2000-01-01

    Managed care organizations (MCOs) face an uncertain future. While consolidation and price competition have expanded their market share, health care expenditures are expected to rise in the near future, and the cost containment premise--and promise--of MCOs is being threatened by mixed blessing and nonsupportive stakeholders. To shed light on MCOs' situation, we discuss four drivers for change in health management in the U.S.: technology, regulation, consumerism, and demographics. Using those four drivers, we then assess the various stakeholders in the industry through a competitive analysis and a stakeholder analysis. These analyses suggest that the munificence of the MCO business environment has significantly declined, especially among supplier and buyer stakeholders. Hence, MCOs cannot continue to manage health care costs alone as this will no longer generate sufficient support among buyer and supplier stakeholders. Instead, MCOs must tackle five critical health care issues by working closely with other stakeholders and also by learning what they can from innovative health care initiatives both inside and outside the United States.

    Full Text Available This article discusses the significance of the achievements of the COST 271 Action on science and technology for space weather and telecommunications in Europe and the world. The Action's work has impacted national and international projects and the decision processes. The key words encompassed in the title of COST 271 are «space weather». But as the reader of this Final Report will appreciate, many more topics were addressed during the Action by the large team of workers from a wide range of countries and organisations than this wording would suggest. Relevant to the performance of telecommunication systems that rely on the presence of the ionosphere for propagation support, or that are affected by transmission through it, there have been investigations among other items of solar and magnetosphere disturbances on the ionosphere, satellite and ground-based measurements of the ionosphere, assembly of near-real-time databases of ionosphere information on the Web, studies of planetary and gravity waves in the ionosphere, ionosphere modelling, mapping and forecasting, long-term changes, ray-path deviations in the presence of irregularities, channel-scattering functions, and scintillations on Earth-space paths. The impact of all this work on the outside communities can be considered within three broad headings as follows.

    2012-03-01

    Explaining the evolution of sex is challenging for biologists. A 'twofold cost' compared with asexual reproduction is often quoted. If a cost of this magnitude exists, the benefits of sex must be large for it to have evolved and be maintained. Focusing on benefits can be misleading, as this sidelines important questions about the cost of sex: what is the source of the twofold cost: males, genome dilution or both? Does the cost deviate from twofold? What other factors make sex costly? How should the costs of sex be empirically measured? The total cost of sex and how it varies in different contexts must be known to determine the benefits needed to account for the origin and maintenance of sex. Copyright © 2011 Elsevier Ltd.

    2015-10-01

    Full Text Available The main purpose of this research is to present a way for organizing the accountancy under the conditions of applying the method of standard costs, such that to allow both the registration of standard and effective costs and the separate registration of the deviations from standard costs. Making some pertinent and performance decisions is mainly influenced by the quality of the information provided to managers and by the promptitude they are sent. This desiderate is not possible if using classical methods for calculating costs, reason for which it is mandatory to organize and implement a managerial accountancy, based on using a modern method, namely the method of standard costs. The main implications of this method consist of establishing a pertinent cost, orientated towards the entity management, regardless the activity domain where it is implemented. The carried out study concerns only one of the phases performed for applying the method of standard cost, respectively the organization of the standard costs accountancy.

    The question of wind integration cost has received much attention in the past several years. The methodological challenges to calculating integration costs are discussed in this paper. There are other sources of integration cost unrelated to wind energy. A performance-based approach would be technology neutral, and would provide price signals for all technology types. However, it is difficult to correctly formulate such an approach. Determining what is and is not an integration cost is challenging. Another problem is the allocation of system costs to one source. Because of significant nonlinearities, this can prove to be impossible to determine in an accurate and objective way.

    The aim of this study was (a) to estimate the cost of dementia in Switzerland, (b) to compare the average annual cost for people with dementia who live at home and those living in an institution and (c) to analyse how the average cost per person with dementia who lives at home increases with the severity of dementia. This prevalence-based cost-of-illness study from a societal perspective combined top-down and bottom-up approaches and included both direct and indirect costs of dementia. Cost estimations were based on Swiss national statistics and surveys, as well as international reviews and expert interviews. The total annual cost of dementia amounted up to CHF 6.3 billion for the year 2007. Together, institutional and informal care accounted for over 90% of the cost. The average annual cost was estimated at CHF 55'300 per person with dementia who lives at home and at CHF 68'900 per person who lives in an institution. The cost per person living at home with severe dementia was nearly five times the cost per person with mild dementia. The present study indicates that dementia imposes a considerable economic burden on Swiss society. The cost of dementia is dominated by the costs of care. Diagnosis and treatment related costs are minor. These findings are consistent with contemporary international studies on the subject. The contribution of informal caregivers is substantial since they account for 44% of the total cost of dementia (based on market cost valuation). Given demographic developments in Switzerland, healthcare decision making should have an interest in securing this potential for the future.

  11. Cost Overruns and Cost Estimation in the North Sea

    Energy Technology Data Exchange (ETDEWEB)

    Emhjellen, Magne; Emhjellen, Kjetil; Osmundsen, Petter

    2001-10-01

    Recently, a Norwegian government report on the cost overruns of projects in the North Sea was presented (NOU 1999:11). It concluded that there was a 25% increase in development costs from project sanction (POD, Plan for Operation and Development) to last CCE (Capital Cost Estimate) for the 11 oil field projects investigated. Many reasons like unclear project assumptions in early phase, optimistic interpolation of previous project assumptions, too optimistic estimates, and underestimation of uncertainty were given as reasons for overruns. In this article we highlight the possibility that the cost overruns are not necessarily all due to the reasons given, but also to an error in the estimation and reporting of the capital expenditure cost (CAPEX). Usually the CAPEX is given by a single cost figure, with some indication of its probability distribution. The oil companies report, and are required to do so by government authorities, the estimated 50/50 (median) cost estimate instead of the estimated expected value cost estimate. We demonstrate how the practice of using a 50/50 (median) CAPEX estimate for the 11 projects when the cost uncertainty distributions are asymmetric, may explain at least part of the ''overruns''. Hence, we advocate changing the practice of using 50/50 cost estimates instead of expected value cost estimates for project management and decision purposes. (author)

    Full Text Available Switching cost is defined as possible costs that customers may encounter when they want to change the firm they buy service, and an important subject in terms of accounting services. Particularly, small business entrepreneurs’ not having knowledge about accounting procedures, and sharing private information with accounting firms make switching costs more important for accounting services. Thus, the aim of this study is to investigate the concept of switching costs (relational cost, procedural cost and financial cost, its determinants (perceived service quality, service importance, and service failures, and consequences (re-purchasing, and recommen ding to others. Theresearch was conducted on small business entrepreneurs in down-town of Balıkesir in Turkey. Total 405 small business entrepreneur owners were interviewed. According to results of the study, perceived service quality positively affects all dimensions of switching costs, significance of service positively affects procedural and relational costs, and service failures negatively affect procedural and relational costs. The results showed that while procedural and relational costs positively affect re-purchasing and recommending to others variables, financial cost did not have any effect on these variables.

  19. The Costs of Knowledge

    2008-01-01

    Acquiring knowledge-genuinely learning something new-requires the consent and commitment of the person you're trying to learn from. In contrast to information, which can usually be effectively transmitted in a document or diagram, knowledge comes from explaining, clarifying, questioning, and sometimes actually working together. Getting this kind of attention and commitment often involves some form of negotiation, since even the most generous person's time and energy are limited. Few experts sit around waiting to share their knowledge with strangers or casual acquaintances. In reasonably collaborative enterprises- I think NASA is one-this sort of negotiation isn't too onerous. People want to help each other and share what they know, so the "cost" of acquiring knowledge is relatively low. In many organizations (and many communities and countries), however, there are considerable costs associated with this activity, and many situations in which negotiations fail. The greatest knowledge cost is in and adopting knowledge to one's own use. Sometimes this means formally organizing what one learns in writing. Sometimes it means just taking time to reflect on someone else's thoughts and experiences-thinking about knowledge that is not exactly what you need but can lead you to develop ideas that will be useful. A long, discursive conversation, with all the back-and-forth that defines conversation, can be a mechanism of knowledge exchange. I have seen many participants at NASA APPEL Masters Forums talking, reflecting, and thinking-adapting what they are hearing to their own needs. Knowledge transfer is not a simple proposition. An enormous amount of information flows through the world every day, but knowledge is local, contextual, and "stickyn-that is, it takes real effort to move it from one place to another. There is no way around this. To really learn a subject, you have to work at it, you have to pay your "knowledge dues." So while, thanks to advances in technology

    Intensive care unit (ICU) costs account for a great part of a hospital's expenses. The objective of the present study was to measure the patient-specific cost of ICU treatment, to identify the most important cost drivers in ICU and to examine the role of various contributing factors in cost configuration. A retrospective cost analysis of all ICU patients who were admitted during 2011 in a Greek General, seven-bed ICU and stayed for at least 24hours was performed, by applying bottom-up analysis. Data collected included demographics and the exact cost of every single material used for patients' care. Prices were yielded from the hospital's purchasing costs and from the national price list of the imaging and laboratory tests, which was provided by the Ministry of Health. A total of 138 patients were included. Variable cost per ICU day was €573.18. A substantial cost variation was found in the total costs obtained for individual patients (median: €3443, range: €243.70-€116,355). Medicines were responsible for more than half of the cost and antibiotics accounted for the largest part of it, followed by blood products and cardiovascular drugs. Medical cause of admission, severe illness and increased length of stay, mechanical ventilation and dialysis were the factors associated with cost escalation. ICU variable cost is patient-specific, varies according to each patient's needs and is influenced by several factors. The exact estimation of variable cost is a pre-requisite in order to control ICU expenses.

    Full Text Available The Danish Ministry of Culture has funded a project to set up a model for costing preservation of digital materials held by national cultural heritage institutions. The overall objective of the project was to increase cost effectiveness of digital preservation activities and to provide a basis for comparing and estimating future cost requirements for digital preservation. In this study we describe an activity-based costing methodology for digital preservation based on the Open Archice Information System (OAIS Reference Model. Within this framework, which we denote the Cost Model for Digital Preservation (CMDP, the focus is on costing the functional entity Preservation Planning from the OAIS and digital migration activities. In order to estimate these costs we have identified cost-critical activities by analysing the functions in the OAIS model and the flows between them. The analysis has been supplemented with findings from the literature, and our own knowledge and experience. The identified cost-critical activities have subsequently been deconstructed into measurable components, cost dependencies have been examined, and the resulting equations expressed in a spreadsheet. Currently the model can calculate the cost of different migration scenarios for a series of preservation formats for text, images, sound, video, geodata, and spreadsheets. In order to verify the model it has been tested on cost data from two different migration projects at the Danish National Archives (DNA. The study found that the OAIS model provides a sound overall framework for the cost breakdown, but that some functions need additional detailing in order to cost activities accurately. Running the two sets of empirical data showed among other things that the model underestimates the cost of manpower-intensive migration projects, while it reinstates an often underestimated cost, which is the cost of developing migration software. The model has proven useful for estimating the

    Recent resource assessments conducted by the United States Department of Energy have identified significant opportunities for expanding hydropower generation through the addition of power to non-powered dams and on undeveloped stream-reaches. Additional interest exists in the powering of existing water resource infrastructure such as conduits and canals, upgrading and expanding existing hydropower facilities, and the construction new pumped storage hydropower. Understanding the potential future role of these hydropower resources in the nation’s energy system requires an assessment of the environmental and techno-economic issues associated with expanding hydropower generation. To facilitate these assessments, this report seeks to fill the current gaps in publically available hydropower cost-estimating tools that can support the national-scale evaluation of hydropower resources.

    This fact sheet is an overview of the systems integration subprogram at the U.S. Department of Energy SunShot Initiative. Soft costs can vary significantly as a result of a fragmented energy marketplace. In the U.S., there are 18,000 jurisdictions and 3,000 utilities with different rules and regulations for how to go solar. The same solar equipment may vary widely in its final installation price due to process and market variations across jurisdictions, creating barriers to rapid industry growth. SunShot supports the development of innovative solutions that enable communities to build their local economies and establish clean energy initiatives that meet their needs, while at the same time creating sustainable solar market conditions.

    The immunization status of children is improved by interventions that increase community demand for compulsory and non-compulsory vaccines, one of the most important interventions related to immunization providers. The aim of this study is to evaluate the activities of immunization providers in terms of activities time and cost, to calculate the immunization doses cost, and to determine the immunization dose errors cost. Time-motion and cost analysis study design was used. Five public health clinics in Mosul-Iraq participated in the study. Fifty (50) vaccine doses were required to estimate activities time and cost. Micro-costing method was used; time and cost data were collected for each immunization-related activity performed by the clinic staff. A stopwatch was used to measure the duration of activity interactions between the parents and clinic staff. The immunization service cost was calculated by multiplying the average salary/min by activity time per minute. 528 immunization cards of Iraqi children were scanned to determine the number and the cost of immunization doses errors (extraimmunization doses and invalid doses). The average time for child registration was 6.7 min per each immunization dose, and the physician spent more than 10 min per dose. Nurses needed more than 5 min to complete child vaccination. The total cost of immunization activities was 1.67 US$ per each immunization dose. Measles vaccine (fifth dose) has a lower price (0.42 US$) than all other immunization doses. The cost of a total of 288 invalid doses was 744.55 US$ and the cost of a total of 195 extra immunization doses was 503.85 US$. The time spent on physicians' activities was longer than that spent on registrars' and nurses' activities. Physician total cost was higher than registrar cost and nurse cost. The total immunization cost will increase by about 13.3% owing to dose errors.

  9. Costing blood products and services.

    At present, blood centers and transfusion services have limited alternatives for offsetting the ever-rising costs of health care inputs. In the face of current revenue constraints, cost reduction or cost containment through efficiency improvements or service reduction is the principal available means. Such methods ought to be pursued vigorously by blood bankers with the aid of well-designed costing and other physical measurements systems. Experience indicates, however, that blood bankers, in their attempts to reduce or contain costs, are likely to place undue reliance on cost accounting systems as the means of capturing sought-for benefits. Management must learn enough about methods of costing to judge directly the uses and limitations of the information produced. Such understanding begins with recognition that all costs and cost comparisons should be specific to the purpose for which they are developed. No costing procedure is capable of producing measures generally applicable to all management decisions. A measure relevant to a planning decision is unlikely to be appropriate for performance evaluation. Useful comparisons among sets of organizations of costs, or of measures of physical inputs and outputs, require assurance that the methods of measurement employed are the same and that the sets of organizations from which the measures are drawn are reasonably comparable.

  10. Realistic costs of carbon capture

    There is a growing interest in carbon capture and storage (CCS) as a means of reducing carbon dioxide (CO2) emissions. However there are substantial uncertainties about the costs of CCS. Costs for pre-combustion capture with compression (i.e. excluding costs of transport and storage and any revenue from EOR associated with storage) are examined in this discussion paper for First-of-a-Kind (FOAK) plant and for more mature technologies, or Nth-of-a-Kind plant (NOAK). For FOAK plant using solid fuels the levelised cost of electricity on a 2008 basis is approximately 10 cents/kWh higher with capture than for conventional plants (with a range of 8-12 cents/kWh). Costs of abatement are found typically to be approximately US$150/tCO2 avoided (with a range of US$120-180/tCO2 avoided). For NOAK plants the additional cost of electricity with capture is approximately 2-5 cents/kWh, with costs of the range of US$35-70/tCO2 avoided. Costs of abatement with carbon capture for other fuels and technologies are also estimated for NOAK plants. The costs of abatement are calculated with reference to conventional SCPC plant for both emissions and costs of electricity. Estimates for both FOAK and NOAK are mainly based on cost data from 2008, which was at the end of a period of sustained escalation in the costs of power generation plant and other large capital projects. There are now indications of costs falling from these levels. This may reduce the costs of abatement and costs presented here may be 'peak of the market' estimates. If general cost levels return, for example, to those prevailing in 2005 to 2006 (by which time significant cost escalation had already occurred from previous levels), then costs of capture and compression for FOAK plants are expected to be US$110/tCO2 avoided (with a range of US$90-135/tCO2 avoided). For NOAK plants costs are expected to be US$25-50/tCO2. Based on these considerations a likely representative range of costs of abatement from CCS

  2. Cost-effectiveness analysis in markets with high fixed costs.

    Cutler, David M; Ericson, Keith M Marzilli

    We consider how to conduct cost-effectiveness analysis when the social cost of a resource differs from the posted price. From the social perspective, the true cost of a medical intervention is the marginal cost of delivering another unit of a treatment, plus the social cost (deadweight loss) of raising the revenue to fund the treatment. We focus on pharmaceutical prices, which have high markups over marginal cost due to the monopoly power granted to pharmaceutical companies when drugs are under patent. We find that the social cost of a branded drug is approximately one-half the market price when the treatment is paid for by a public insurance plan and one-third the market price for mandated coverage by private insurance. We illustrate the importance of correctly accounting for social costs using two examples: coverage for statin drugs and approval for a drug to treat kidney cancer (sorafenib). In each case, we show that the correct social perspective for cost-effectiveness analysis would be more lenient than researcher recommendations.

  3. Cost-effective nursing practice: cost-awareness and empowerment.

    1993-12-01

    Cost-effective nursing practice is essential to succeed today as resources allocated to health care are declining. Realizing that any change poses a threat to our security, it is imperative that stakeholders be permitted to participate in decision-making processes affecting their work. An honest, open exchange of ideas towards cost-effective practices should be encouraged. Cost-effective behaviours are influenced significantly by negative attitudes with regard to loss of human resources, increased workload, and potential pay cuts. This article describes innovative strategies which could promote successful cost-effective nursing practice, including working smarter, not working harder. Topics addressed are attitude, awareness and empowerment.

  4. Costs of Globalization

    Full Text Available Globalization has both costs and benefits. In this paper we would focus upon one of the damages of globalization to China. It is said that inward FDI replaces local domestic capabilities in import-substitution countries. In the case of China the Chinese domesticindustries are lacking technological innovations because of heavy reliance upon FDI. Most of the Chinese exports of electronics are carried under FDI whereas in Korea and Japan they are indigenously-driven. In 1960s, Korea received foreign capital in the formof loans but it denied the entrance to foreign firms. Korea followed the Japanese model by quickly mastering the foreign technology rather than letting foreign firms to establish local subsidiaries and to decide the speed and scope of technology diffusion. Korea andJapan adopted the techno-nationalist policies for attaining autonomous domestic innovated industries. By restricting FDI, Korea and Japan were able to maintain their management independent of Multi-National Companies. In this paper we would try to analyze that whether China’s policy of reliance upon FDI is a success or a debacle by comparing it with Korea and Japan.

    In a way to reduce the external energy dependence, increasing also the investments in renewable energy sources and aiming for the concretization of the European renewable objectives, the Portuguese government defined a goal of 5100 MW of installed wind power, up to 2012. If the drawn objectives are accomplished, by 2010 the wind power share may reach values comparable to leading countries like Denmark, Germany or Spain. The Portuguese forecasts also indicate a reinforcement of the natural gas fired generation in particular through the use of the combined cycle technology, following the European tendency. This analysis sets out to evaluate the total generating cost of wind power and CCGT in Portugal. A life cycle cost analysis was conducted, including investment costs, O and M costs, fuel costs and external costs of emissions, for each type of technology. For the evaluation of the externalities ExternE values were used. The results show that presently the wind power production cost is higher than the CCGT one, at least from the strictly financial point of view. CCGT costs increase significantly when charges for externalities are included. However, they only reach levels higher than the equivalents for wind power for high externality costs estimations. This partially results from the low load factor of the wind farms in Portugal and also from the low emission levels of the gas fired technology used in the comparison. A sensitive analysis of the technical and economical parameters was also conducted. Particular attention was given to the natural gas prices due to the possible increase over time. The fuel escalation rate is the parameter that has larger effects on the final costs. It was verified that the total cost of wind plant is more influenced by the load factor than the total cost of CCGT. (au)

    Examining a state-dependent pricing model in the presence of menu costs and dynamic duopolistic interactions, this paper claims that the assumption regarding market structure is crucial for iden- tifying the menu costs for price changes. Prices in a dynamic duopolistic market can be more rigid than those in more competitive markets, such as a monopolistic-competition market. Therefore, the estimates of menu costs under monopolistic competition are potentially biased upward due to the price ri...

    We motivate and introduce an extension of the well-known cumulative constraint which deals with time and volume dependent cost of resources. Our research is primarily interested in scheduling problems under time and volume variable electricity costs, but the constraint equally applies to manpower scheduling when hourly rates differ over time and/or extra personnel incur higher hourly rates. We present a number of possible lower bounds on the cost, including a min-cost flow, different LP and MIP models, as well as greedy algorithms, and provide a theoretical and experimental comparison of the different methods.

  20. Cost-shifting under cost reimbursement and prospective payment.

    Science.gov (United States)

    Foster, R W

    1985-09-01

    Cost-shifting is seen as a three-way phenomenon involving hospital interests as well as those of government and private patients. Without economies of scale, private patients are indifferent to government policies unless underpayment leads to hospital bankruptcy. In the presence of economies of scale, private patients benefit from reductions in government payment under either cost reimbursement or prospective payment. Their interest in a shift to prospective payment depends upon the hospital's location on its cost curve. Hospitals benefit from increases in payment rates in all cases, but benefit from a shift to prospective payment only if operating in a region of declining average costs. The conventional view of cost-shifting is inconsistent with profit maximization and may be inappropriate for many voluntary hospitals as well.

    Previous studies to determine the cost of haemodialysis (HD) in Spain have significant limitations: they are outdated or used indirect methods. There is also a lack of analysis performed simultaneously on Public centres (PC), with direct HD services, and partially state-subsidised centres (SC). This is an important issue since the two systems coexist in Spain. To estimate the cost of HD replacement therapy for chronic renal failure in several centres. This is a prospective and publicly-funded study, which estimates the costs for 2008 using a cost accounting system with specific allocation criteria. We collected demographic and comorbidity data for each centre. Six centres participated, two PC and four SC. There were no significant differences between centres in terms of patient demographics, time on haemodialysis and the Charlson comorbidity index. The total cost per patient per year ranged between € 46, 254 and € 33,130. The cost per patient per year (excluding vascular access and hospital admission) for PC was € 42, 547 and € 39, 289 and for SC € 32 872, € 29, 786, € 35, 461 and € 35, 294 (23% more in PC than SC). Costs related to staff/patient/year and consumables/patient/year were 67% and 83% respectively, higher for PC than SC. The highest percentage cost was for staff (average 30.9%), which showed significant variability between centres, both in absolute numbers (staff cost per patient per year between € 18,151 and € 8504) and as a percentage (between 42.6 % and 25.4%). Cost variability exists among different HD centres, and this can be attributed primarily to staff and consumables costs, which is higher for PC than SC.

    2012-05-01

    Despite its prevalence and deleterious impact on patients and families, fecal incontinence remains an understudied condition. Few data are available on its economic burden in the United States. The aim of this study was to quantify per patient annual economic costs associated with fecal incontinence. A mail survey of patients with fecal incontinence was conducted in 2010 to collect information on their sociodemographic characteristics, fecal incontinence symptoms, and utilization of medical and nonmedical resources for fecal incontinence. The analysis was conducted from a societal perspective and included both direct and indirect (ie, productivity loss) costs. Unit costs were determined based on standard Medicare reimbursement rates, national average wholesale prices of medications, and estimates from other relevant sources. All cost estimates were reported in 2010 US dollars. This study was conducted at a single tertiary care institution. The analysis included 332 adult patients who had fecal incontinence for more than a year with at least monthly leakage of solid, liquid, or mucous stool. The primary outcome measured was the per patient annual economic costs associated with fecal incontinence. The average annual total cost for fecal incontinence was $4110 per person (median = $1594; interquartile range, $517-$5164). Of these costs, direct medical and nonmedical costs averaged $2353 (median, $1176; interquartile range, $294-$2438) and $209 (median, $75; interquartile range, $17-$262), whereas the indirect cost associated with productivity loss averaged $1549 per patient annually (median, $0; interquartile range, $0-$813). Multivariate regression analyses suggested that greater fecal incontinence symptom severity was significantly associated with higher annual direct costs. This study was based on patient self-reported data, and the sample was derived from a single institution. Fecal incontinence is associated with substantial economic cost, calling for more

    2015-04-01

    Full Text Available The opportunity cost of the capital invested in pharmaceutical research and development (R&D to bring a new drug to market makes up as much as half the total cost. However, the literature on the cost of pharmaceutical R&D is mixed on how, exactly, one should calculate this “hidden” cost. Some authors attempt to adopt models from the field of finance, whereas other prominent authors dismiss this practice as biased, arguing that it artificially inflates the R&D cost to justify higher prices for pharmaceuticals. In this article, we examine the arguments made by both sides of the debate and then explain the cost of capital concept and describe in detail how this value is calculated. Given the significant contribution of the cost of capital to the overall cost of new drug R&D, a clear understanding of the concept is critical for policy makers, investors, and those involved directly in the R&D.

    - Two recent societal cost-benefit analyses have documented the costs of smoking and the cost-effectiveness of preventing smoking.- Smoking costs the Netherlands society EUR 33 billion per year.- The majority of this is the monetary value of health loss; these are "soft" euros that cannot be re-spent.- There is not a great deal of difference between costs and benefits when expressed in "hard" euros, which means that there is no clear business case for anti-smoking policy.- The greatest benefit of discouraging smoking is improved health for the individual and increased productivity for the business sector; however, the benefits cannot be easily realised, because even in the most favourable scenario the number of smokers will decrease slowly.- Excise duties seem to offer the most promising avenue for combating smoking. The benefits of anti-smoking policy, therefore, consist mainly of tax revenues for the government.- Stringent policy is required to transform tax revenues into health gains.

  20. Asynchronous Capacity per Unit Cost

    CERN Document Server

    Chandar, Venkat; Tse, David

    2010-01-01

    The capacity per unit cost, or equivalently minimum cost to transmit one bit, is a well-studied quantity. It has been studied under the assumption of full synchrony between the transmitter and the receiver. In many applications, such as sensor networks, transmissions are very bursty, with small amounts of bits arriving infrequently at random times. In such scenarios, the cost of acquiring synchronization is significant and one is interested in the fundamental limits on communication without assuming a priori synchronization. In this paper, we show that the minimum cost to transmit B bits of information asynchronously is (B + \\bar{H})k_sync, where k_sync is the synchronous minimum cost per bit and \\bar{H} is a measure of timing uncertainty equal to the entropy for most reasonable arrival time distributions.

  1. Sequential Construction of Costly Networks

    Energy Technology Data Exchange (ETDEWEB)

    Gutfraind, Alexander [Los Alamos National Laboratory

    2011-01-01

    Natural disasters or attacks often disrupt infrastructure networks requiring a costly recovery. This motivates an optimization problem where the objecitve is to construct the nodes of a graph G(V;E), and the cost of each node is dependent on the number of its neighbors previously constructed, or more generally, any properties of the previously-completed subgraph. In this optimization problem the objective is to find a permutation of the nodes which results in the least construction cost. We prove that in the case where the cost of nodes is a convex function in the number of neighbors, the optimal construction sequence is to start at a single node and move outwards. We also introduce algorithms and heuristics for solving various instances of the problem. Those methods can be applied to help reduce the cost of recovering from disasters as well as to plan the deployment of new network infrastructure.

    We have overestimated the ability of electronic health records (EHR) systems to enhance efficiency by eliminating transcription and the need to physically pull charts. Hospital managers typically underestimate the costs of upgrade fees and support. To avoid this problem, hospitals must develop a full total cost of ownership (TCO) analysis to independently forecast total lifecycle costs for EHR information technology. Vendor information must be checked for validity and a milestone payment schedule must be devised to pay for results (outcomes) not promises. Vendors vary widely in their capacity to set up a fully functional inpatient-outpatient EHR system. Documentation programming will help to control hospital costs while enhancing service quality and staff morale. This study presents cost analysis from 62 hospitals in 16 cities during the period 2012-2013.

  4. The Psychology of Cost Estimating

    Cost estimation for large (and even not so large) government programs is a challenge. The number and magnitude of cost overruns associated with large Department of Defense (DoD) and National Aeronautics and Space Administration (NASA) programs highlight the difficulties in developing and promulgating accurate cost estimates. These overruns can be the result of inadequate technology readiness or requirements definition, the whims of politicians or government bureaucrats, or even as failures of the cost estimating profession itself. However, there may be another reason for cost overruns that is right in front of us, but only recently have we begun to grasp it: the fact that cost estimators and their customers are human. The last 70+ years of research into human psychology and behavioral economics have yielded amazing findings into how we humans process and use information to make judgments and decisions. What these scientists have uncovered is surprising: humans are often irrational and illogical beings, making decisions based on factors such as emotion and perception, rather than facts and data. These built-in biases to our thinking directly affect how we develop our cost estimates and how those cost estimates are used. We cost estimators can use this knowledge of biases to improve our cost estimates and also to improve how we communicate and work with our customers. By understanding how our customers think, and more importantly, why they think the way they do, we can have more productive relationships and greater influence. By using psychology to our advantage, we can more effectively help the decision maker and our organizations make fact-based decisions.

  6. Do hospital mergers reduce costs?

    Science.gov (United States)

    Schmitt, Matt

    2017-03-01

    Proponents of hospital consolidation claim that mergers lead to significant cost savings, but there is little systematic evidence backing these claims. For a large sample of hospital mergers between 2000 and 2010, I estimate difference-in-differences models that compare cost trends at acquired hospitals to cost trends at hospitals whose ownership did not change. I find evidence of economically and statistically significant cost reductions at acquired hospitals. On average, acquired hospitals realize cost savings between 4 and 7 percent in the years following the acquisition. These results are robust to a variety of different control strategies, and do not appear to be easily explained by post-merger changes in service and/or patient mix. I then explore several extensions of the results to examine (a) whether the acquiring hospital/system realizes cost savings post-merger and (b) if cost savings depend on the size of the acquirer and/or the geographic overlap of the merging hospitals.

  7. Cost allocation in distribution planning

    Energy Technology Data Exchange (ETDEWEB)

    Engevall, S.

    1996-12-31

    This thesis concerns cost allocation problems in distribution planning. The cost allocation problems we study are illustrated using the distribution planning situation at the Logistics department of Norsk Hydro Olje AB. The planning situation is modeled as a Traveling Salesman Problem and a Vehicle Routing Problem with an inhomogeneous fleet. The cost allocation problems are the problems of how to divide the transportation costs among the customers served in each problem. The cost allocation problems are formulated as cooperative games, in characteristic function form, where the customers are defined to be the players. The games contain five and 21 players respectively. Game theoretical solution concepts such as the core, the nucleolus, the Shapley value and the {tau}-value are discussed. From the empirical results we can, among other things, conclude that the core of the Traveling Salesman Game is large, and that the core of the Vehicle Routing Game is empty. In the accounting of Norsk Hydro the cost per m{sup 3} can be found for each tour. We conclude that for a certain definition of the characteristic function, a cost allocation according to this principle will not be included in the core of the Traveling Salesman Game. The models and methods presented in this thesis can be applied to transportation problems similar to that of Norsk Hydro, independent of the type of products that are delivered. 96 refs, 11 figs, 26 tabs

    Coast, Joanna; Smith, Richard D

    2003-08-01

    There is growing evidence that antimicrobial resistance causes serious consequences for individuals as well as leading to increased healthcare costs. The containment of resistance is therefore a policy problem which will impact on all health systems in the next few years. Unfortunately, there is, as yet, no definitive evidence suggesting that particular control measures are successful in containing either the emergence or transmission of antimicrobial resistance. Furthermore, few studies contain information about costs and even where there is such information it is generally inadequate because of the narrow perspectives from which analyses are conducted. In part, this is due to methodological problems associated with the inclusion of cost data: measuring and valuing what are often intangible costs; identifying costs associated with organizational change; and accounting for interaction between costs at levels from the individual to the international. Good quality research, including both economic evaluation and comprehensive economic modelling, is required to determine the most cost-effective combination of strategies to pursue in combating resistance, and to find ways around these methodological difficulties.

    Cost is a key issue in the spreading of any technology. In this work, the cost of hydrogen is analyzed and determined, for hydrogen obtained by electrolysis. Different contributing partial costs are taken into account to calculate the hydrogen final cost, such as energy and electrolyzers taxes. Energy cost data is taken from official URLs, while electrolyzer costs are obtained from commercial companies. The analysis is accomplished under different hypothesis, and for different countries: Germany, France, Austria, Switzerland, Spain and the Canadian region of Ontario. Finally, the obtained costs are compared to those of the most used fossil fuels, both in the automotive industry (gasoline and diesel) and in the residential sector (butane, coal, town gas and wood), and the possibilities of hydrogen competing against fuels are discussed. According to this work, in the automotive industry, even neglecting subsidies, hydrogen can compete with fossil fuels. Hydrogen can also compete with gaseous domestic fuels. Electrolyzer prices were found to have the highest influence on hydrogen prices. (orig.)

    2015-10-01

    The cost of childhood stroke receives little notice. The authors examined potential drivers of cost and outcome to test whether (1) neonatal strokes cost less than childhood strokes, (2) associated diseases influence cost, (3) arterial ischemic stroke is more costly than sinovenous thrombosis, and (4) cost correlates with outcome. The authors reviewed records of 111 children who sustained arterial ischemic stroke or sinovenous thrombosis between 2005 and 2010 to identify costs for the following year. They assessed outcomes in 46 with the Recovery and Recurrence Questionnaire and the Pediatric Quality of Life Inventory. Neonatal strokes cost less than childhood stroke. Strokes associated with congenital heart disease or vasculopathy cost the most, while perinatal or idiopathic strokes cost the least. Higher costs are correlated with worse impairment and poorer quality of life. Stroke etiology significantly influences the cost of pediatric stroke. Future cost-benefit studies must consider etiology when estimating the incremental costs associated with stroke.

    1988-01-01

    Cost consciousness was given a very necessary boost by the collapse of oil prices in 1986 and downward movements in prices have served to re-inforce the need for vigilance: oil companies were becoming complacent. The climate necessary for cost consciousness to flourish as part of the oil company culture is established by higher management attitude and can be reinforced by organizational structure. British Petroleum's current production/exploration organisational structure is reported on in the first section of this paper and this is followed by a discussion of pertinent cost-oriented observations to emerge from this grouping related both to the component phases of the exploitation of a field, and to the cost of engineering/managing same.

    CERN Document Server

    Tulabandhula, Theja

    2011-01-01

    This work concerns the way that statistical models are used to make decisions. In particular, we aim to merge the way estimation algorithms are designed with how they are used for a subsequent task. Our methodology considers the operational cost of carrying out a policy, based on a predictive model. The operational cost becomes a regularization term in the learning algorithm's objective function, allowing either an \\textit{optimistic} or \\textit{pessimistic} view of possible costs. Limiting the operational cost reduces the hypothesis space for the predictive model, and can thus improve generalization. We show that different types of operational problems can lead to the same type of restriction on the hypothesis space, namely the restriction to an intersection of an $\\ell_{q}$ ball with a halfspace. We bound the complexity of such hypothesis spaces by proposing a technique that involves counting integer points in polyhedrons.

  2. Mental fatigue: costs and benefits.

    Science.gov (United States)

    Boksem, Maarten A S; Tops, Mattie

    2008-11-01

    A framework for mental fatigue is proposed, that involves an integrated evaluation of both expected rewards and energetical costs associated with continued performance. Adequate evaluation of predicted rewards and potential risks of actions is essential for successful adaptive behaviour. However, while both rewards and punishments can motivate to engage in activities, both types of motivated behaviour are associated with energetical costs. We will review findings that suggest that the nucleus accumbens, orbitofrontal cortex, amygdala, insula and anterior cingulate cortex are involved evaluating both the potential rewards associated with performing a task, as well as assessing the energetical demands involved in task performance. Behaviour will only proceed if this evaluation turns out favourably towards spending (additional) energy. We propose that this evaluation of predicted rewards and energetical costs is central to the phenomenon of mental fatigue: people will no longer be motivated to engage in task performance when energetical costs are perceived to outweigh predicted rewards.

    Higbee, Charles V.

    1998-01-01

    In the early 1970s, life cycle costing (LCC) was adopted by the federal government. LCC is a method of evaluating all the costs associated with acquisition, construction and operation of a project. LCC was designed to minimize costs of major projects, not only in consideration of acquisition and construction, but especially to emphasize the reduction of operation and maintenance costs during the project life. Authors of engineering economics texts have been very reluctant and painfully slow to explain and deal with LCC. Many authors devote less than one page to the subject. The reason for this is that LCC has several major drawbacks. The first of these is that costs over the life of the project must be estimated based on some forecast, and forecasts have proven to be highly variable and frequently inaccurate. The second problem with LCC is that some life span must be selected over which to evaluate the project, and many projects, especially renewable energy projects, are expected to have an unlimited life (they are expected to live for ever). The longer the life cycle, the more inaccurate annual costs become because of the inability to forecast accurately.

    The primary objective of this work is to provide guidelines to estimate the decommissioning cost as well as the stakeholders with plausible information to understand the decommissioning activities in a reasonable manner, which eventually contribute to acquiring the public acceptance for the nuclear power industry. Although several cases of the decommissioning cost estimate have been made for a few commercial nuclear power plants, the different technical, site-specific and economic assumptions used make it difficult to interpret those cost estimates and compare them with that of a relevant plant. Trustworthy cost estimates are crucial to plan a safe and economic decommissioning project. The typical approach is to break down the decommissioning project into a series of discrete and measurable work activities. Although plant specific differences derived from the economic and technical assumptions make a licensee difficult to estimate reliable decommissioning costs, estimating decommissioning costs is the most crucial processes since it encompasses all the spectrum of activities from the planning to the final evaluation on whether a decommissioning project has successfully been preceded from the perspective of safety and economic points. Hence, it is clear that tenacious efforts should be needed to successfully perform the decommissioning project.

    Despite growing recognition of the negative externalities associated with reactive nitrogen (N), the damage costs of N to air, water, and climate remain largely unquantified. We propose a comprehensive approach for estimating the social cost of nitrogen (SCN), defined as the present value of the monetary damages caused by an incremental increase in N. This framework advances N accounting by considering how each form of N causes damages at specific locations as it cascades through the environment. We apply the approach to an empirical example that estimates the SCN for N applied as fertilizer. We track impacts of N through its transformation into atmospheric and aquatic pools and estimate the distribution of associated costs to affected populations. Our results confirm that there is no uniform SCN. Instead, changes in N management will result in different N-related costs depending on where N moves and the location, vulnerability, and preferences of populations affected by N. For example, we found that the SCN per kilogram of N fertilizer applied in Minnesota ranges over several orders of magnitude, from less than $0.001/kg N to greater than $10/kg N, illustrating the importance of considering the site, the form of N, and end points of interest rather than assuming a uniform cost for damages. Our approach for estimating the SCN demonstrates the potential of integrated biophysical and economic models to illuminate the costs and benefits of N and inform more strategic and efficient N management.

  8. Regression Testing Cost Reduction Suite

    Mohamed Alaa El-Din

    2014-08-01

    Full Text Available The estimated cost of software maintenance exceeds 70 percent of total software costs [1], and large portion of this maintenance expenses is devoted to regression testing. Regression testing is an expensive and frequently executed maintenance activity used to revalidate the modified software. Any reduction in the cost of regression testing would help to reduce the software maintenance cost. Test suites once developed are reused and updated frequently as the software evolves. As a result, some test cases in the test suite may become redundant when the software is modified over time since the requirements covered by them are also covered by other test cases. Due to the resource and time constraints for re-executing large test suites, it is important to develop techniques to minimize available test suites by removing redundant test cases. In general, the test suite minimization problem is NP complete. This paper focuses on proposing an effective approach for reducing the cost of regression testing process. The proposed approach is applied on real-time case study. It was found that the reduction in cost of regression testing for each regression testing cycle is ranging highly improved in the case of programs containing high number of selected statements which in turn maximize the benefits of using it in regression testing of complex software systems. The reduction in the regression test suite size will reduce the effort and time required by the testing teams to execute the regression test suite. Since regression testing is done more frequently in software maintenance phase, the overall software maintenance cost can be reduced considerably by applying the proposed approach.

  9. Metabolic Cost of Experimental Exercises

    Webb, James T.; Gernhardt, Michael L.

    2009-01-01

    Although the type and duration of activity during decompression was well documented, the metabolic cost of 1665 subject-exposures with 8 activity profiles from 17 altitude decompression sickness (DCS) protocols at Brooks City-Base, TX from 1983-2005 was not determined. Female and male human volunteers (30 planned, 4 completed) performed activity profiles matching those 8 activity profiles at ground level with continuous monitoring of metabolic cost. A Cosmed K4b2 Cardio Pulmonary Exercise Testing device was used to measure oxygen uptake (VO2) during the profiles. The results show levels of metabolic cost to the females for the profiles tested varied from 4.3 to 25.5 ml/kg/min and from 3.0 to 12.0 ml/kg/min to the males. The increase in VO2 from seated rest to the most strenuous of the 8 activity profiles was 3.6-fold for the females and 2.8-fold for the males. These preliminary data on 4 subjects indicate close agreement of oxygen uptake for activity performed during many subject-exposures as published earlier. The relatively low average oxygen uptake required to perform the most strenuous activity may imply the need for adjustment of modeling efforts using metabolic cost as a risk factor. Better definition of metabolic cost during exposure to altitude, a critical factor in DCS risk, may allow refinement of DCS prediction models.

    2010-01-01

    Concurrent engineering taking into account product life-cycle factors seems to be one of the industrial challenges of the next years. Cost estimation and management are two main strategic tasks that imply the possibility of managing costs at the earliest stages of product development. This is why it is indispensable to let people from economics and from industrial engineering collaborates in order to find the best solution for enterprise progress for economical factors mastering. The objective of this paper is to present who we try to adapt costing methods in a PLM and CE point of view to the new industrial context and configuration in order to give pertinent decision aid for product and process choices. A very important factor is related to cost management problems when developing new products. A case study is introduced that presents how product development actors have referenced elements to product life-cycle costs and impacts, how they have an idea bout economical indicators when taking decisions during t...

    2015-01-01

    It is estimated that in Poland about 400,000 persons in general suffer from inflammatory joint diseases, including rheumatoid arthritis (RA). Epidemiological surveys documenting the frequency and disturbance of musculoskeletal disorders in the Polish population are few in number. Most of the estimations are based on epidemiological data from other countries (prevalence of 0.5-1%). According to the data of the National Health Fund in Poland 135,000-157,000 persons in total are treated because of rheumatoid arthritis per year [ICD10 (International Statistical Classification of Diseases and Related Health Problems): M05, M06]. In the case of this group of diseases indirect costs significantly outweigh the direct costs. Indirect costs increase together with activity level of the disease. The cost analysis of productivity loss of RA patients indicates that sickness absenteeism and informal care are the most burdensome. At the national level it amounts in total from 1.2 billion to 2.8 billion PLN per year, depending on the method of analysis. These costs could be significantly reduced through early diagnosis and introduction of effective treatment.

  12. Minimizing activated carbons production cost

    2009-07-15

    A detailed economic evaluation of activated carbons production process from various raw materials is undertaken using the conventional economic indices (ROI, POT, and NPV). The fundamental factors that affect production cost were taken into account. It is concluded that for an attractive investment in activated carbons production one should select the raw material with the highest product yield, adopt a chemical activation production scheme and should base product price on product-surface area (or more generally on product adsorption capacity for the adsorbate in consideration). A raw material that well meets the above-mentioned criteria is petroleum coke but others are also promising (charcoals, and carbon black). Production cost then can be optimized by determining its minimum value of cost that results from the intercept between the curves of plant capacity and raw material cost - if any. Taking into account the complexity of such a techno-economic analysis, a useful suggestion could be to start the evaluations from a plant capacity corresponding to the break-even point, i. e. the capacity at which income equals production cost.

    Full Text Available Activity based costing is a method of identifying and tracking the operating costs directly associated with processing items. It is the practice of focusing on some unit of output, such as a purchase order or an assembled automobile and attempting to determine its total as precisely as poccible based on the fixed and variable costs of the inputs.You use ABC to identify, quantify and analyze the various cost drivers (such as labor, materials, administrative overhead, rework. and to determine which ones are candidates for reduction.A processes any activity that accepts inputs, adds value to these inputs for customers and produces outputs for these customers. The customer may be either internal or external to the organization. Every activity within an organization comprimes one or more processes. Inputs, controls and resources are all supplied to the process.A process owner is the person responsible for performing and or controlling the activity.The direction of cost through their contact to partial activity and processes is a new modern theme today. Beginning of this method is connected with very important changes in the firm processes.ABC method is a instrument , that bring a competitive advantages for the firm.

    2010-01-01

    We discuss the problem of building a compiler which can lift in a provably correct way pieces of information on the execution cost of the object code to cost annotations on the source code. To this end, we need a clear and flexible picture of: (i) the meaning of cost annotations, (ii) the method to prove them sound and precise, and (iii) the way such proofs can be composed. We propose a so-called labelling approach to these three questions. As a first step, we examine its application to a toy compiler. This formal study suggests that the labelling approach has good compositionality and scalability properties. In order to provide further evidence for this claim, we report our successful experience in implementing and testing the labelling approach on top of a prototype compiler written in OCAML for (a large fragment of) the C language.

    Healthcare leaders should address three important questions as they prepare to implement new costing systems: Do all providers in their organizations' systems, networks, or partnerships share the same definitions of unit of care and of fixed, variable, incremental, direct, and indirect costs? What are the maintenance processes and protocols for cost center and period matching of revenues and costs? If some providers within a network or partnership are not using costing systems, can an enterprise derive surrogate cost per unit of care?

  1. Sartans: differences, similitudes and costs

    Orietta Zaniolo

    Full Text Available The search for a more specific and complete blockade of the hypertensive effects of angiotensin and of better tolerability than ACE-inhibitors has led to the development of angiotensin II receptor blockers (ARBs, which were introduced about 10 years ago. During this period they have been evaluated in several large studies in terms of efficacy and safety in reducing blood pressure, as well as for cardiovascular and renal protection. In patients with heart failure, valsartan, candesartan and, partially, losartan have been shown to be associated with positive outcomes both as monotherapy, when ACE-inhibitors are contraindicated or not tolerated, and in combination with ACE-inhibitors standard therapy. Among ARBs, valsartan is the only that is also approved for treatment of patients with both heart failure and recent myocardial infarction. In light of the high costs related to cardiovascular disorders, agents that reduce cardiovascular risk, like ARBs, represent a potential long-term health cost saving strategy, if used according to guidelines in approved indications. Valsartan has a daily cost which is lower than the mean cost of the class. Furthermore, this drug shows one of the lowest costs for patient brought to blood pressure goals in its class. In this paper, economic evaluations conducted on the results of large trials were reviewed. Their results add economic rationale to the therapeutic algorithms recommended by clinical guidelines on heart failure management; using valsartan, or other evaluated ARBs, in heart failure patients who are intolerant or contraindicated to ACE-inhibitors therapy, is expected to be highly cost/effective. In combination with ACE-inhibitors in those patients not on beta-blocker therapy, its cost/effectiveness is somewhat worse, but still acceptable, with an estimated cost of 15,000 USDs for life year saved. In summary, when used for approved indications, valsartan offers attractive economic features for the

    With the increase of style variation, decrease of lot size and shortening of lead-time, production planning becomes a big problem in clothing industry. It was found that changeover cost is one of key factors in garment production. In this paper, based on time measurement and the data collected, considering the relevent elements such as previous experience, lot size, number of lines,the effect of changeover cost on garment production is calculated and analyzed. Then some suggestions are put forward for manufacturers to balance their production planning.

  4. Cost and color of photosynthesis.

    Science.gov (United States)

    Marosvölgyi, Marcell A; van Gorkom, Hans J

    2010-02-01

    The question of why plants are green has been revisited in several articles recently. A common theme in the discussions is to explain why photosynthesis appears to absorb less of the available green sunlight than expected. The expectation is incorrect, however, because it fails to take the energy cost of the photosynthetic apparatus into account. Depending on that cost, the red absorption band of the chlorophylls may be closely optimized to provide maximum growth power. The optimization predicts a strong influence of Fraunhofer lines in the solar irradiance on the spectral shape of the optimized absorption band, which appears to be correct. It does not predict any absorption at other wavelengths.

    A cost-accounting analysis can help group practices assess their costs of doing business and determine the profitability of managed care contracts. Group practices also can use cost accounting to develop budgets and financial benchmarks. To begin a cost analysis, group practices need to determine their revenue and cost centers. Then they can allocate their costs to each center, using an appropriate allocation basis. The next step is to calculate costs per procedure. The results can be used to evaluate operational cost efficiency as well as help negotiate managed care contracts.

  9. Estimating nursing costs--a methodological review.

    Science.gov (United States)

    Chiang, Bea

    2009-05-01

    A critical cost accounting issue relating to nursing costs is that nursing costs are currently averaged into the daily room rate in the hospitals. This accounting practice treats nursing units as cost centers as nursing costs are bundled into a per diem rate instead of billed separately. As a result, all patients in a given care unit of the hospital are presumed to consume the same amount of nursing care resources. This costing and billing system creates a mismatch between resources consumption and billed charges. The objective of this paper is to (1) demonstrate current practice to estimate nursing costs, (2) classify nursing costs into direct and indirect costs in order to refine the existing approaches and (3) argue that a system of billing nursing costs separately better reflects the costs of patient care.

    The total cost of a 25 W average load magnetic refrigerator using commercial grade Gd is calculated using a numerical model. The price of magnetocaloric material, magnet material and cost of operation are considered, and all influence the total cost. The lowest combined total cost with a device...... lifetime of 15 years is found to be in the range $150-$400 depending on the price of the magnetocaloric and magnet material. The cost of the magnet is largest, followed closely by the cost of operation, while the cost of the magnetocaloric material is almost negligible. For the lowest cost device...... characteristics are based on the performance of a conventional A+++ refrigeration unit. In a rough life time cost comparison between the AMR device and such a unit we find similar costs, the AMR being slightly cheaper, assuming the cost of the magnet can be recuperated at end of life....

This solution allows decentralized mode of operation and the aim of this work is implementation of controlling and diagnostic mechanism into an electric scooter project realized at Technical university of Ostrava. In todays world which now fully enjoys the prime of electromobility, off-grid battery systems and other, it is important to seek the optimal balance between functionality and the economy side of BMS that being electronics which deals with secondary cells of batery packs. There were numerous sophisticated, but not too practical BMS models in the past, such as centralized system or standalone balance modules of individual cells. This article aims at development of standalone balance modules which are able to communicate with the coordinator, adjust their parameters and ensure their cells safety in case of a communication failure. With the current worldwide cutting cost trend in mind, the emphasis was put on the lowest price possible for individual component. The article is divided into two major categories, the first one being desing of power electronics with emphasis on quality, safety (cooling) and also cost. The second part describes development of a communication interface with reliability and cost in mind. The article contains numerous graphs from practical measurements. The outcome of the work and its possible future is defined in the conclusion.

    Life Cycle Costing (LCC) is always a major concern in the Architecture, Engineering and Coustruction (AEC) industry. This paper presents the implementation of Building Information Modeling (BIM) technology in the development of a lifecycle cost-estimating tool. The IFC (Industry Foundation Classes) model as an interoperable building information model has been adopted as the central data repository to deliver the integrated information of building designs from CAD design systems into the lifecycle-costing database. In this paper, the coneeptions and relevant factors, which could affect the LCC estimation, have been introduced. The problems of current lCC applications have been identified as the lack of LCC data and the complexity of LCC exercises.The software application of IFC models and relevant auxiliary are depicted as a solution of the problem identified. The lifccycle costing tool is a part of the nD Modeling tool and as such is based on its integrated interface prototype toolkit and is able to holistically present an IFC model into a 3D virtual reality view, a tree-view and a list of element properties. The functions and some technical points are also detailed in the paper. Through the research, it demonstrates the potential and possibility of implementing BIM methods and techniques, particularly IFCs to enhance the computer applications in the processes of building construction and faeility management.

    Lab experiments on punishment are of limited relevance for understanding cooperative behavior in the real world. In real interactions, punishment is not cheap, but the costs of punishment are of a different nature than in experiments. They do not correspond to direct payments or payoff deductions, b

  7. Minimum Covering with Travel Cost

    CERN Document Server

    Fekete, Sandor P; Schmidt, Christiane

    2011-01-01

    Given a polygon and a visibility range, the Myopic Watchman Problem with Discrete Vision (MWPDV) asks for a closed path P and a set of scan points S, such that (i) every point of the polygon is within visibility range of a scan point; and (ii) path length plus weighted sum of scan number along the tour is minimized. Alternatively, the bicriteria problem (ii') aims at minimizing both scan number and tour length. We consider both lawn mowing (in which tour and scan points may leave P) and milling (in which tour, scan points and visibility must stay within P) variants for the MWPDV; even for simple special cases, these problems are NP-hard. We show that this problem is NP-hard, even for the special cases of rectilinear polygons and L_\\infty scan range 1, and negligible small travel cost or negligible travel cost. For rectilinear MWPDV milling in grid polygons we present a 2.5-approximation with unit scan range; this holds for the bicriteria version, thus for any linear combination of travel cost and scan cost. F...

  9. Model adjointization and its cost

    CHENG Qiang; ZHANG Linbo; WANG Bin

    2004-01-01

    In this article, the least program behavior decomposition method (LPBD) is put forward from a program structure point of view. This method can be extensively used both in algorithms of automatic differentiation (AD) and in tools design, and does not require programs to be evenly separable but the cost in terms of operations count and memory is similar to methods using checkpointing. This article starts by summarizing the rules of adjointization and then presents the implementation of LPBD. Next, the definition of the separable program space, based on the fundamental assumptions (FA) of automatic differentiation, is given and the differentiation cost functions are derived. Also,two constants of fundamental importance in AD, σ and μ, are derived under FA. Under the assumption of even separability, the adjoint cost of simple and deep decomposition is subsequently discussed quantitatively using checkpointing. Finally, the adjoint costs in terms of operations count and memory through the LPBD method are shown to be uniformly dependent on the depth of structure or decomposition.

  11. [Cost of dialysis in France].

    2016-04-01

    According to latest data published by the French health authority (HAS), nearly 74,000 French patients in end-stage chronic renal disease are following a replacement therapy. They were 61,000 in 2007, amounting to a cost of 4 billions euros for public health insurance. The cost varies depending on the age and comorbidities. Continuous ambulatory peritoneal dialysis is the cheapest mode of treatment, while the heavy haemodialysis centres costs are close to twice as expensive. But these two different treatments are - a priori - not applied for the same patients in terms of level of severity of disease. Moreover, associated costs, medical treatment, transportation, etc. are to be taken into account, as well as losses of income for patients facing major job difficulties. As recommended by HAS experts, it will be important to regularly conduct surveys allowing a regular economic assessment of the various modes of financial healthcare for end-stage chronic renal disease.

    Various studies show that raising the temperature as well as storms, cold snap, raining and drought caused by climate change. And variety disasters have had a damage to mankind. The world risk report(2012, The Nature Conservancy) and UNU-EHS (the United Nations University Institute for Environment and Human Security) reported that more and more people are exposed to abnormal weather such as floods, drought, earthquakes, typhoons and hurricanes over the world. In particular, the case of Korea, we influenced by various pollutants which are occurred in Northeast Asian countries, China and Japan, due to geographical meteorological characteristics. These contaminants have had a significant impact on air quality with the pollutants generated in Korea. Recently, around the world continued their effort to reduce greenhouse gas and to improve air quality in conjunction with the national or regional development goals priority. China is also working on various efforts in accordance with the international flows to cope with climate change and air pollution. In the future, effect of climate change and air quality in Korea and Northeast Asia will be change greatly according to China's growth and mitigation policies. The purpose of this study is to minimize the damage caused by climate change on the Korean peninsula through an integrated approach taking into account the mitigation and adaptation plan. This study will suggest a climate change strategy at the national level by means of a comprehensive economic analysis of the impacts and mitigation of climate change. In order to quantify the impact and damage cost caused by climate change scenarios in a regional scale, it should be priority variables selected in accordance with impact assessment of climate change. The sectoral impact assessment was carried out on the basis of selected variables and through this, to derive the methodology how to estimate damage cost and adaptation cost. And then, the methodology was applied in Korea

  14. Cost effectiveness in trauma care.

    Science.gov (United States)

    Elliott, D C; Rodriguez, A

    1996-02-01

    The above discussion brings together a vast body of data that together proclaim with fervent clarity: Traumatic injuries are expensive. The expense is paid in productive lives lost, in permanent disability, in pain and suffering, and in health care resources consumed. As local and regional trauma systems struggle for development and survival, competition for the health care dollar casts in the additional necessity of providing the service of trauma care with maximum efficiency. Despite the variety of cost-efficiency measures described above, a majority of trauma centers continue to operate "in the red." Such cannot continue indefinitely. Fiscal responsibility dictates that health care institutions must balance budgets in order to maintain operations. Four primary strategies for cost containment appear from the above discussion: 1. Improve reimbursement rates from trauma patients. 2. Increase outside funding from government sources. 3. Improve cost efficiency of diagnostic and therapeutic procedures used in trauma patient management. 4. Increase efforts aimed at primary prevention of intentional and unintentional injuries. In the final analysis, most authors agree that the last strategy offers the best hope. As stated in their article, "The Economic Impact of Injuries," Harlan and colleagues conclude that "the most effective medical and cost reduction strategy would be prevention." The same article goes on to detail how greater funding for research into optimal prevention modalities could reap societal and economic benefits far beyond the value of the initial outlay. Yet such research funding continues to be inadequate. For every dollar spent on medical care of cancer patients, nine cents is directed to research. For every dollar spent on trauma care, less than a penny is spent on research. Until the public recognizes the terrible toll trauma extracts in lives, livelihood, and money wasted and until it realizes the pre-eminent importance of prevention, care of the

  18. Low Cost Hydrogen Production Platform

    Energy Technology Data Exchange (ETDEWEB)

    Timothy M. Aaron, Jerome T. Jankowiak

    2009-10-16

    A technology and design evaluation was carried out for the development of a turnkey hydrogen production system in the range of 2.4 - 12 kg/h of hydrogen. The design is based on existing SMR technology and existing chemical processes and technologies to meet the design objectives. Consequently, the system design consists of a steam methane reformer, PSA system for hydrogen purification, natural gas compression, steam generation and all components and heat exchangers required for the production of hydrogen. The focus of the program is on packaging, system integration and an overall step change in the cost of capital required for the production of hydrogen at small scale. To assist in this effort, subcontractors were brought in to evaluate the design concepts and to assist in meeting the overall goals of the program. Praxair supplied the overall system and process design and the subcontractors were used to evaluate the components and system from a manufacturing and overall design optimization viewpoint. Design for manufacturing and assembly (DFMA) techniques, computer models and laboratory/full-scale testing of components were utilized to optimize the design during all phases of the design development. Early in the program evaluation, a review of existing Praxair hydrogen facilities showed that over 50% of the installed cost of a SMR based hydrogen plant is associated with the high temperature components (reformer, shift, steam generation, and various high temperature heat exchange). The main effort of the initial phase of the program was to develop an integrated high temperature component for these related functions. Initially, six independent concepts were developed and the processes were modeled to determine overall feasibility. The six concepts were eventually narrowed down to the highest potential concept. A US patent was awarded in February 2009 for the Praxair integrated high temperature component design. A risk analysis of the high temperature component was

  13. The Cost of Railroad Regulation

    DEFF Research Database (Denmark)

    Federico, Giovanni; Sharp, Paul R.

    We investigate the costs of transportation regulation using the example of agricultural markets in the United States. Using a large database of prices by state of agricultural commodities, we find that the coefficient of variation (as a measure of market integration between states) falls for many...... commodities until the First World War. We demonstrate that this reflected changes in transportation costs which in turn in the long run depended on productivity growth in railroads. 1920 marked a change in this relationship, however, and between the First and Second World Wars we find considerable...... disintegration of agricultural markets, ultimately as a consequence of the 1920 Transportation Act. We argue that this benefited railroad companies in the 1920s and workers in the 1930s, and we put forward an estimate of the welfare losses for the consumers of railroad services (i.e. agricultural producers...

  14. Thermodynamic cost of external control

    Science.gov (United States)

    Barato, Andre C.; Seifert, Udo

    2017-07-01

    Artificial molecular machines are often driven by the periodic variation of an external parameter. This external control exerts work on the system of which a part can be extracted as output if the system runs against an applied load. Usually, the thermodynamic cost of the process that generates the external control is ignored. Here, we derive a refined second law for such small machines that include this cost, which is, for example, generated by free energy consumption of a chemical reaction that modifies the energy landscape for such a machine. In the limit of irreversible control, this refined second law becomes the standard one. Beyond this ideal limiting case, our analysis shows that due to a new entropic term unexpected regimes can occur: the control work can be smaller than the extracted work and the work required to generate the control can be smaller than this control work. Our general inequalities are illustrated by a paradigmatic three-state system.

    Yang, Yongheng; Koutroulis, Eftichios; Sangwongwanich, Ariya

    2017-01-01

    Countries with considerable PhotoVoltaic (PV) installations are facing a challenge of overloading their power grid during peak-power production hours if the power infrastructure remains the same. To address this, regulations have been imposed on PV systems, where more active power control should...... be flexibly performed. As an advanced control strategy, the Absolute Active Power Control (AAPC) can effectively solve the overloading issues by limiting the maximum possible PV power to a certain level (i.e., the power limitation), and also benefit the inverter reliability due to the reduction in the thermal...... loading of the power devices. However, its feasibility is challenged by the associated energy losses. An increase of the inverter lifetime and a reduction of the energy yield can alter the cost of energy, demanding an optimization of the power limitation. Therefore, aiming at minimizing the Levelized Cost...

  16. Cost Estimates and Investment Decisions

    Energy Technology Data Exchange (ETDEWEB)

    Emhjellen, Kjetil; Emhjellen Magne; Osmundsen, Petter

    2001-08-01

    When evaluating new investment projects, oil companies traditionally use the discounted cashflow method. This method requires expected cashflows in the numerator and a risk adjusted required rate of return in the denominator in order to calculate net present value. The capital expenditure (CAPEX) of a project is one of the major cashflows used to calculate net present value. Usually the CAPEX is given by a single cost figure, with some indication of its probability distribution. In the oil industry and many other industries, it is common practice to report a CAPEX that is the estimated 50/50 (median) CAPEX instead of the estimated expected (expected value) CAPEX. In this article we demonstrate how the practice of using a 50/50 (median) CAPEX, when the cost distributions are asymmetric, causes project valuation errors and therefore may lead to wrong investment decisions with acceptance of projects that have negative net present values.

    This paper constructs a dynamic model of the equilibrium determination of relative prices when arbitragers face holding costs. The major findings are that 1) models based on riskless arbitrage arguments alone may not provide usefully tight bounds on observed prices, 2) arbitragers are often most effective in eliminating the mispricings of shorter-term assets, 3) arbitrage activity increases the mean reversion of changes in the mispricing process and reduces their conditional volatility, and 4...

    Mercury (Hg) has been used for millennia in many applications, primarily in artisanal mining and as an electrode in the chlor-alkali industry. It is anthropogenically emitted as a pollutant from coal fired power plants and naturally emitted, primarily from volcanoes. Its unique chemical characteristics enable global atmospheric transport and it is deposited after various processes, ultimately ending up in one of its final sinks, such as incorporated into deep sediment or bioaccumulated, primarily in the marine environment. All forms of Hg have been established as toxic, and there have been no noted biological benefits from the metal. Throughout time, there have been notable incidents of Hg intoxication documented, and the negative health effects have been documented to those chronically or acutely exposed. Today, exposure to Hg is largely diet or occupationally dependent, however, many are exposed to Hg from their amalgam fillings. This paper puts a tentative monetary value on Hg polluted food sources in the Arctic, where local, significant pollution sources are limited, and relates this to costs for strategies avoiding Hg pollution and to remediation costs of contaminated sites in Sweden and Japan. The case studies are compiled to help policy makers and the public to evaluate whether the benefits to the global environment from banning Hg and limiting its initial emission outweigh the benefits from its continued use or lack of control of Hg emissions. The cases we studied are relevant for point pollution sources globally and their remediation costs ranged between 2500 and 1.1 million US$ kg{sup -1} Hg isolated from the biosphere. Therefore, regulations discontinuing mercury uses combined with extensive flue gas cleaning for all power plants and waste incinerators is cost effective. (author)

  4. The relative cost of biomass energy transport.

    Searcy, Erin; Flynn, Peter; Ghafoori, Emad; Kumar, Amit

    2007-04-01

    Logistics cost, the cost of moving feedstock or products, is a key component of the overall cost of recovering energy from biomass. In this study, we calculate for small- and large-project sizes, the relative cost of transportation by truck, rail, ship, and pipeline for three biomass feedstocks, by truck and pipeline for ethanol, and by transmission line for electrical power. Distance fixed costs (loading and unloading) and distance variable costs (transport, including power losses during transmission), are calculated for each biomass type and mode of transportation. Costs are normalized to a common basis of a giga Joules of biomass. The relative cost of moving products vs feedstock is an approximate measure of the incentive for location of biomass processing at the source of biomass, rather than at the point of ultimate consumption of produced energy. In general, the cost of transporting biomass is more than the cost of transporting its energy products. The gap in cost for transporting biomass vs power is significantly higher than the incremental cost of building and operating a power plant remote from a transmission grid. The cost of power transmission and ethanol transport by pipeline is highly dependent on scale of project. Transport of ethanol by truck has a lower cost than by pipeline up to capacities of 1800 t/d. The high cost of transshipment to a ship precludes shipping from being an economical mode of transport for distances less than 800 km (woodchips) and 1500 km (baled agricultural residues).

  5. Laboratory cost control and financial management software.

    Mayer, M

    1998-02-09

    Economical constraints within the health care system advocate the introduction of tighter control of costs in clinical laboratories. Detailed cost information forms the basis for cost control and financial management. Based on the cost information, proper decisions regarding priorities, procedure choices, personnel policies and investments can be made. This presentation outlines some principles of cost analysis, describes common limitations of cost analysis, and exemplifies use of software to achieve optimized cost control. One commercially available cost analysis software, LabCost, is described in some detail. In addition to provision of cost information, LabCost also serves as a general management tool for resource handling, accounting, inventory management and billing. The application of LabCost in the selection process of a new high throughput analyzer for a large clinical chemistry service is taken as an example for decisions that can be assisted by cost evaluation. It is concluded that laboratory management that wisely utilizes cost analysis to support the decision-making process will undoubtedly have a clear advantage over those laboratories that fail to employ cost considerations to guide their actions.

    2013-10-01

    Full Text Available Nowadays exponential advancement in reversible comp utation has lead to better fabrication and integration process. It has become very popular ove r the last few years since reversible logic circuit s dramatically reduce energy loss. It consumes less p ower by recovering bit loss from its unique input-o utput mapping. This paper presents two new gates called RC-I and RC-II to design an n-bit signed binary comparator where simulation results show that the p roposed circuit works correctly and gives significa ntly better performance than the existing counterparts. An algorithm has been presented in this paper for constructing an optimized reversible n-bit signed c omparator circuit. Moreover some lower bounds have been proposed on the quantum cost, the numbers of g ates used and the number of garbage outputs generated for designing a low cost reversible sign ed comparator. The comparative study shows that the proposed design exhibits superior performance consi dering all the efficiency parameters of reversible logic design which includes number of gates used, quantum cost, garbage output and constant inputs. This proposed design has certainly outperformed all the other existing approaches.

  7. Hospital cost accounting and the new imperative.

    Sabin, P

    1987-05-01

    Government regulatory structures, prospective payment mechanisms, a more competitive environment, and attempts to link cost accounting principles to planning, budgeting, and fiscal control all have served as catalysts for hospitals to increase their reliance and emphasis on cost accounting. Current hospital accounting systems are relatively inexpensive to develop and maintain, and they fulfill the financial reporting requirements mandated by Medicare and other third-party payers. These systems, however, do not provide information on what specific service units cost, and managers must have this information to make optimal trade-offs between quality, availability, and cost of medical services. Most health care organizations have a predetermined charge for each type of service, but the charge may not accurately portray the cost of providing the service. Knowing true costs will enable managers to select the most cost-effective method of treating a patient; know the financial implications of adding tests or procedures; relate costs to established norms of care; establish ranges of acceptable costs in various diagnostic groups; negotiate more successfully with rate review organizations and health maintenance organizations; and vigorously market and advertise the services that most contribute to the organization's overall financial health. The goal of microcosting is to determine the full cost of providing specific service units. The microcosting process comprises three components: data collection, cost modeling, and cost analysis. Microcosting is used to determine full costs for 20 percent of the hospital's procedures that are responsible for generating 80 percent of the hospital's gross revenue. Full costs are established by adding labor costs, materials costs, equipment depreciation costs, departmental overhead costs, and corporate overhead costs.(ABSTRACT TRUNCATED AT 250 WORDS)

  8. Correlation, Cost Risk, and Geometry

    Science.gov (United States)

    Dean, Edwin B.

    1992-01-01

    The geometric viewpoint identifies the choice of a correlation matrix for the simulation of cost risk with the pairwise choice of data vectors corresponding to the parameters used to obtain cost risk. The correlation coefficient is the cosine of the angle between the data vectors after translation to an origin at the mean and normalization for magnitude. Thus correlation is equivalent to expressing the data in terms of a non orthogonal basis. To understand the many resulting phenomena requires the use of the tensor concept of raising the index to transform the measured and observed covariant components into contravariant components before vector addition can be applied. The geometric viewpoint also demonstrates that correlation and covariance are geometric properties, as opposed to purely statistical properties, of the variates. Thus, variates from different distributions may be correlated, as desired, after selection from independent distributions. By determining the principal components of the correlation matrix, variates with the desired mean, magnitude, and correlation can be generated through linear transforms which include the eigenvalues and the eigenvectors of the correlation matrix. The conversion of the data to a non orthogonal basis uses a compound linear transformation which distorts or stretches the data space. Hence, the correlated data does not have the same properties as the uncorrelated data used to generate it. This phenomena is responsible for seemingly strange observations such as the fact that the marginal distributions of the correlated data can be quite different from the distributions used to generate the data. The joint effect of statistical distributions and correlation remains a fertile area for further research. In terms of application to cost estimating, the geometric approach demonstrates that the estimator must have data and must understand that data in order to properly choose the correlation matrix appropriate for a given estimate

    2012-01-01

    Full Text Available Railroad maintenance engineering plays an important role on availability of roads and reducing the cost of railroad incidents. Rail is of the most important parts of railroad industry, which needs regular maintenance since it covers a significant part of total maintenance cost. Any attempt on optimizing total cost of maintenance could substantially reduce the cost of railroad system and it can reduce total cost of the industry. The paper presents a new method to estimate the cost of rail failure using different cost components such as cost of inspection and cost of risk associated with possible accidents. The proposed model of this paper is used for a real-world case study of railroad transportation of Tehran region and the results have been analyzed.

    Stirk, Charles W.; Liu, Qin; Ball, Matthew V.

    1999-04-01

    This paper analyzes the manufacturing cost of photonic system using software that combines several methods for accurate cost accounting. Activity based costing assigns al capital equipment, material and labor costs directly to the product rather than to overheads. Cost of ownership models determine the cost of using machines under different financial and utilization scenarios. Libraries of standard machines, process steps, and process sequences facilitate rapid model building and modification. Using libraries for semiconductor and photonics fabrication, along with packaging and optomechanical assembly, we construct cost models for 2D VCSEL array communication modules. The result of the analysis is that the model cost is driven mainly by the epitaxial material cost, and laser yield limits VCSEL arrays to small scale integration.

    1992-01-01

    The suitable structure for an effective and accurate cost estimate for general purposes is discussed in the context of a NASA technology program. Cost elements are defined for research, management, and facility-construction portions of technology programs. Attention is given to the mechanisms for insuring the viability of spending programs, and the need for program managers is established for effecting timely fund disbursement. Formal, structures, and intuitive techniques are discussed for cost-estimate development, and cost-estimate defensibility can be improved with increased documentation. NASA policies for cash management are examined to demonstrate the importance of the ability to obligate funds and the ability to cost contracted funds. The NASA approach to consistent cost justification is set forth with a list of standard cost-element definitions. The cost elements reflect the three primary concerns of cost estimates: the identification of major assumptions, the specification of secondary analytic assumptions, and the status of program factors.

  15. Incorporating psychological influences in probabilistic cost analysis

    Kujawski, Edouard; Alvaro, Mariana; Edwards, William

    2004-01-08

    Today's typical probabilistic cost analysis assumes an ''ideal'' project that is devoid of the human and organizational considerations that heavily influence the success and cost of real-world projects. In the real world ''Money Allocated Is Money Spent'' (MAIMS principle); cost underruns are rarely available to protect against cost overruns while task overruns are passed on to the total project cost. Realistic cost estimates therefore require a modified probabilistic cost analysis that simultaneously models the cost management strategy including budget allocation. Psychological influences such as overconfidence in assessing uncertainties and dependencies among cost elements and risks are other important considerations that are generally not addressed. It should then be no surprise that actual project costs often exceed the initial estimates and are delivered late and/or with a reduced scope. This paper presents a practical probabilistic cost analysis model that incorporates recent findings in human behavior and judgment under uncertainty, dependencies among cost elements, the MAIMS principle, and project management practices. Uncertain cost elements are elicited from experts using the direct fractile assessment method and fitted with three-parameter Weibull distributions. The full correlation matrix is specified in terms of two parameters that characterize correlations among cost elements in the same and in different subsystems. The analysis is readily implemented using standard Monte Carlo simulation tools such as {at}Risk and Crystal Ball{reg_sign}. The analysis of a representative design and engineering project substantiates that today's typical probabilistic cost analysis is likely to severely underestimate project cost for probability of success values of importance to contractors and procuring activities. The proposed approach provides a framework for developing a viable cost management strategy for

    Feature Based Cost Modeling is thought of as a relative new approach to cost modeling, but feature based cost modeling had considerable development in the 1950's. Considerable work was published in the 1950's by Boeing on cost for various casting processes--sand casting, die casting, investment casting and permanent mold casting--as a function of a single casting feature, casting volume. Additional approaches to feature based cost modeling have been made, and this work is a review of previous works and a proposed integrated model to feature based cost modeling.

    This paper provides estimates of the cost of equity and debt capital to for-profit and non-profit hospitals in the U.S. for the years 1972-83. The cost of equity is estimated using, alternatively, the Capital Asset Pricing Model and Arbitrage Pricing Theory. We find that the cost of equity capital, using either model, substantially exceeded anticipated inflation. The cost of debt capital was much lower. Accounting for the corporate tax shield on debt and capital paybacks by cost-based insurers lowered the net cost of capital to hospitals.

  4. FY 1995 cost savings report

    Andrews-Smith, K.L., Westinghouse Hanford

    1996-06-21

    Fiscal Year (FY) 1995 challenged us to dramatically reduce costs at Hanford. We began the year with an 8 percent reduction in our Environmental Management budget but at the same time were tasked with accomplishing additional workscope. This resulted in a Productivity Challenge whereby we took on more work at the beginning of the year than we had funding to complete. During the year, the Productivity Challenge actually grew to 23 percent because of recissions, Congressional budget reductions, and DOE Headquarters actions. We successfully met our FY 1995 Productivity Challenge through an aggressive cost reduction program that identified and eliminated unnecessary workscope and found ways to be more efficient. We reduced the size of the workforce, cut overhead expenses, eliminated paperwork, cancelled construction of new facilities, and reengineered our processes. We are proving we can get the job done better and for less money at Hanford. DOE`s drive to do it ``better, faster, cheaper`` has led us to look for more and larger partnerships with the private sector. The biggest will be privatization of Hanford`s Tank Waste Remediation System, which will turn liquid tank waste into glass logs for eventual disposal. We will also save millions of dollars and avoid the cost of replacing aging steam plants by contracting Hanford`s energy needs to a private company. Other privatization successes include the Hanford Mail Service, a spinoff of advanced technical training, low level mixed waste thermal treatment, and transfer of the Hanford Museums of Science and history to a private non-profit organization. Despite the rough roads and uncertainty we faced in FY 1995, less than 3 percent of our work fell behind schedule, while the work that was performed was completed with an 8.6 percent cost under-run. We not only met the FY 1995 productivity challenge, we also met our FY 1995-1998 savings commitments and accelerated some critical cleanup milestones. The challenges continue

    Nuclear power is currently the second largest power supply method in Korea and the number of nuclear power plants are planned to be increased as well. However, clear management policy for spent fuels generated from nuclear power plants has not yet been established. The back-end fuel cycle, associated with nuclear material flow after nuclear reactors is a collection of technologies designed for the spent fuel management and the spent fuel management policy is closely related with the selection of a nuclear fuel cycle. Cost is an important consideration in selection of a nuclear fuel cycle and should be determined by adding external cost to private cost. Unlike the private cost, which is a direct cost, studies on the external cost are focused on nuclear reactors and not at the nuclear fuel cycle. In this research, external cost indicators applicable to nuclear fuel cycle were derived and quantified. OT (once through), DUPIC (Direct Use of PWR SF in CANDU), PWR-MOX (PWR PUREX reprocessing), and Pyro-SFR (SFR recycling with pyroprocessing) were selected as nuclear fuel cycles which could be considered for estimating external cost in Korea. Energy supply security cost, accident risk cost, and acceptance cost were defined as external cost according to precedent and estimated after analyzing approaches which have been adopted for estimating external costs on nuclear power generation.

  7. New pharmaceuticals reduce cost of illness.

    Hansen, R W

    1986-06-01

    The cost of illness includes not only the funds required to treat illness, but also the effect on the patient's quality of life. Recent concern about rising health costs have focused on the direct expenditures without noting that the cost of illness in terms of mortality and morbidity has declined significantly. Pharmaceuticals have played a major role in reducing the total cost of illness. Several studies of the cost-effectiveness of past introductions of vaccines and pharmaceuticals reveal large cost savings. Although the focus of most studies has been on major advances, the continuing process of less dramatic therapeutic improvements has significantly trimmed the cost of illness. Cost-benefit studies of new drugs or changes in drug use, while more difficult to perform, make it possible to influence the selection of therapy. Since pharmaceuticals represent less than 10% of total treatment costs, reduction in the cost of pharmaceutical products can only have a minor impact on the total cost of illness. Pharmaceuticals can reduce the cost of illness by providing alternative therapies that reduce direct treatment cost or improve the public health.

    2011-01-01

    Full Text Available Problem statement: Sensor with local processing power that enables it to react to local conditions without having to refer back to the central controller. The size and the cost of smart sensor circuit have been reduced. Approach: The use of microcontroller, such as (PIC16C715, with an 8- bit ADC (Analogue to Digital Converter in one chip. This reduction in the circuit size makes it possible sometimes to incorporate the primary sensor with the signal processing circuit in one unit, then the lookup table should be modified accordingly. The program mobility of smart sensor enables the system to perform self calibration routine by applying known input voltage signal, where its corresponding expected value is stored in the self calibration code. Results: The correction for the measurement signal is done by multiplying the measured signal by the gain correction value and then adding the result of the multiplication to the offset compensation value. The smart sensor performs the self calibration routine for every new measurement value, to adapt any changes in the system environment such as temperature drift. Conclusion: The system performance has been enhanced by implementing the PIC16C715 Circuit design complexity and cost has been reduced and also it’s easy to upgrade.

  12. Environmental protection using social costing

    Energy Technology Data Exchange (ETDEWEB)

    Lee, R.

    1993-10-01

    Emissions and other residual wastes come from industrial production, commercial and household activities, and transportation. These wastes damage the environment, including human health. As economies grow, so does concern about balancing that growth with the desire for environmental protection. At issue is how much environmental protection we should have. We address this issue using the concept of social costing. The issue is discussed in the context of electric power generation. There is particular concern about the use of fossil fuels such as petroleum, the major fuel used in the Republic of China, and coal which is the most common fuel used in the U. S. Electric power generation is a major source of airborne pollutants such as SO{sub 2}, NO{sub x} particulate matter, volatile organic compounds, CO, and CO{sub 2}. It also results in liquid and solid wastes, and other effects such as changes in land use. To generate electric power, fuel (such as petroleum, coal or enriched uranium) or some other resource (e.g., wind or geothermal) is needed. A fuel cycle consists of a sequence of activities and processes involved in generating electric power. These activities include fuel extraction, treatment and processing; fuel conversion into electricity; transmission; waste disposal; and transportation of fuel and wastes between the different stages of the fuel cycle. Each stage results in emissions or other residuals. Several recent-studies have been about the environmental costs of electricity.

    Energy Technology Data Exchange (ETDEWEB)

    Andersen, Joergen

    1998-07-01

    The key issues discussed in this presentation are (1) What are head office costs?, (2) Why is the charging an area of concern for international companies?, (3) Which part of head office costs should be charged?, (4) OECD guidelines on charging. Head office costs are classified as Shareholder costs, Stewardship costs, Costs related to a specific subsidiary or group of subsidiaries (on call), and Costs related to operational activities in the parent company. The OECD reports of 1984 and 1996 are discussed. In Norsk Hydro's experience, the practising of the OECD guidelines by national authorities are confusing and not consistent over time or across borders. To get a better understanding of how charging of corporate head office costs are dealt with on an international level, Norsk Hydro asked Deloitte and Touche in London to carry out a study on international companies' behaviour. Their conclusions are included.

    2013-12-01

    Increasing attention is being focused on reigning in escalating costs of healthcare, i.e. trying to 'bend the cost curve'. In gastroenterology (GI), inpatient hospital care represents a major component of overall costs. This study aimed to characterize the trend in cost of care for GI-related hospitalizations in recent years and to identify the most costly diagnostic groups. All hospital inpatients admitted between January 2008 and December 2009 with a primary diagnosis of one of the six most common GI-related Diagnosis Related Groups (DRGs) in this hospital system were identified; all DRGs contained at least 40 patients during the study period. Patient Level Costing (PLC) was used to express the total cost of hospital care for each patient; PLC comprised a weighted daily bed cost plus cost of all medical services provided (e.g., radiology, pathology tests) calculated according to an activity-based costing approach; cost of medications were excluded. All costs were discounted to 2009 values. Mean length of stay (LOS) was also calculated for each DRG. Over 2 years, 470 patients were admitted with one of the six most common GI DRGs. Mean cost of care increased from 2008 to 2009 for all six DRGs with the steepest increases seen in 'GI hemorrhage (non-complex)' (31 % increase) and 'Cirrhosis/Alcoholic hepatitis (non-complex)' (45 % increase). No differences in readmission rates were observed over time. There was a strong correlation between year-to-year change in costs and change in mean LOS, r = 0.93. The cost of GI-related inpatient care appears to be increasing in recent years with the steepest increases observed in non-complex GI hemorrhage and non-complex Cirrhosis/Alcoholic hepatitis. Efforts to control the increasing costs should focus on these diagnostic categories.

    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

    Choosing an appropriate accounting system for hospital has always been a challenge for hospital managers. Traditional cost system (TCS) causes cost distortions in hospital. Activity-based costing (ABC) method is a new and more effective cost system. This study aimed to compare ABC with TCS method in calculating the unit cost of medical services and to assess its applicability in Kashani Hospital, Shahrekord City, Iran.‎ This cross-sectional study was performed on accounting data of Kashani Hospital in 2013. Data on accounting reports of 2012 and other relevant sources at the end of 2012 were included. To apply ABC method, the hospital was divided into several cost centers and five cost categories were defined: wage, equipment, space, material, and overhead costs. Then activity centers were defined. ABC method was performed into two phases. First, the total costs of cost centers were assigned to activities by using related cost factors. Then the costs of activities were divided to cost objects by using cost drivers. After determining the cost of objects, the cost price of medical services was calculated and compared with those obtained from TCS.‎ The Kashani Hospital had 81 physicians, 306 nurses, and 328 beds with the mean occupancy rate of 67.4% during 2012. Unit cost of medical services, cost price of occupancy bed per day, and cost per outpatient service were calculated. The total unit costs by ABC and TCS were respectively 187.95 and 137.70 USD, showing 50.34 USD more unit cost by ABC method. ABC method represented more accurate information on the major cost components. By utilizing ABC, hospital managers have a valuable accounting system that provides a true insight into the organizational costs of their department.

    2010-01-01

    To analyze the current total cost of systemic therapy for psoriasis and to compare annual trends in the cost of both generic and brand-name therapies with trends in the Consumer Price Index-Urban since 2000. A cost model was developed that includes costs for prescription drugs, office visits, and suggested laboratory tests and monitoring procedures. Annual trends in psoriasis drug costs from 2000 through 2008 were analyzed by calculating the percentage change in the average wholesale price from the previous year; these values were compared with changes in the yearly Consumer Price Index-Urban values. The United States. Total annual costs for systemic psoriasis therapies and trends in cost compared with the trends in Consumer Price Index-Urban values (equivalent to inflation). Current total annual costs for systemic psoriasis therapies ranged from $1197 (methotrexate) to $27,577 (alefacept, two 12-week courses). Trends in the average wholesale price of brand-name psoriasis therapies from 2000 through 2008 demonstrate an average increase of 66% (range, -24% to +316%); thus, costs of several brand-name psoriasis drugs greatly outpaced the rates of inflation for all items and all prescription drugs. Despite the higher monitoring costs associated with traditional systemic therapies, annual costs of biologics exceed those of other available therapies.

    Remer, D. S.

    1977-01-01

    A mathematical model is developed for calculating the life cycle costs for a project where the operating costs increase or decrease in a linear manner with time. The life cycle cost is shown to be a function of the investment costs, initial operating costs, operating cost gradient, project life time, interest rate for capital and salvage value. The results show that the life cycle cost for a project can be grossly underestimated (or overestimated) if the operating costs increase (or decrease) uniformly over time rather than being constant as is often assumed in project economic evaluations. The following range of variables is examined: (1) project life from 2 to 30 years; (2) interest rate from 0 to 15 percent per year; and (3) operating cost gradient from 5 to 90 percent of the initial operating costs. A numerical example plus tables and graphs is given to help calculate project life cycle costs over a wide range of variables.

  18. Costs and prices of single dental fillings in Europe: a micro-costing study.

    Science.gov (United States)

    Tan, Siok Swan; Ken Redekop, W; Rutten, Frans F H

    2008-01-01

    Dental fillings represent an established procedure to treat tooth decay. The present paper provides a cost comparison of dental filling procedures across nine European countries. More specifically, the paper aims to estimate the costs and prices (i.e. reimbursement fees) of a single dental filling procedure in an approximately 12-year-old child with a toothache in a lower molar who presents at a dental practice, as described in a case vignette. Both amalgam and composite fillings were examined. Total costs were determined by identifying resource use and unit costs for the following cost components: diagnostic procedures, labour, materials, drugs, and overheads. Altogether, 49 practices provided data for the cost calculations. Mean total costs per country varied considerably, ranging from 8 euros to 156 euros. Labour costs were the most important cost driver in all practices, comprising 58% of total costs. Overhead costs were the second-most important cost component in the majority of countries. Actual cost differences across practices within countries were relatively small. Cost variations between countries were primarily due to differences in unit costs, especially for labour and overheads, and only to a lesser extent to differences in resource use. Finally, cost estimates for a single dental filling procedure based on reimbursement fees led to an underestimation of the total costs by approximately 50%. Copyright 2008 John Wiley & Sons, Ltd.

  19. Game Theory with Costly Computation

    CERN Document Server

    Halpern, Joseph Y

    2008-01-01

    We develop a general game-theoretic framework for reasoning about strategic agents performing possibly costly computation. In this framework, many traditional game-theoretic results (such as the existence of a Nash equilibrium) no longer hold. Nevertheless, we can use the framework to provide psychologically appealing explanations to observed behavior in well-studied games (such as finitely repeated prisoner's dilemma and rock-paper-scissors). Furthermore, we provide natural conditions on games sufficient to guarantee that equilibria exist. As an application of this framework, we consider a notion of game-theoretic implementation of mediators in computational games. We show that a special case of this notion is equivalent to a variant of the traditional cryptographic definition of protocol security; this result shows that, when taking computation into account, the two approaches used for dealing with "deviating" players in two different communities -- Nash equilibrium in game theory and zero-knowledge "simula...

    CERN Document Server

    Pradillo, Mar; Flix, Josep; Forti, Alessandra; Sciabà, Andrea

    2015-01-01

    The Worldwide LHC Computing Grid project (WLCG) provides the computing and storage resources required by the LHC collaborations to store, process and analyse the 50 Petabytes of data annually generated by the LHC. The WLCG operations are coordinated by a distributed team of managers and experts and performed by people at all participating sites and from all the experiments. Several improvements in the WLCG infrastructure have been implemented during the first long LHC shutdown to prepare for the increasing needs of the experiments during Run2 and beyond. However, constraints in funding will affect not only the computing resources but also the available effort for operations. This paper presents the results of a detailed investigation on the allocation of the effort in the different areas of WLCG operations, identifies the most important sources of inefficiency and proposes viable strategies for optimising the operational cost, taking into account the current trends in the evolution of the computing infrastruc...

Hasta hace poco se consideraba que nuestro cerebro se benefició de la reducción de otros órganos de alto consumo energético para posibilitar su aumento de tamaño, pero nuevos resultados indican que semejante reducción no tuvo lugar ni en mamíferos ni en primates. En cambio, todo parece indicar que la reducción de costes de locomoción, con la adquisición del bipedalismo, pudo contribuir al aumento de tamaño de nuestros cerebros.

  2. Thermodynamic cost of acquiring information.

    Science.gov (United States)

    Micadei, Kaonan; Serra, Roberto M; Céleri, Lucas C

    2013-12-01

    Connections between information theory and thermodynamics have proven to be very useful to establish bounding limits for physical processes. Ideas such as Landauer's erasure principle and information-assisted work extraction have greatly contributed not only to broadening our understanding about the fundamental limits imposed by nature, but also paving the way for practical implementations of information-processing devices. The intricate information-thermodynamics relation also entails a fundamental limit on parameter estimation, establishing a thermodynamic cost for information acquisition. We show that the amount of information that can be encoded in a physical system by means of a unitary process is limited by the dissipated work during the implementation of the process. This includes a thermodynamic tradeoff for information acquisition. Likewise, the information acquisition process is ultimately limited by the second law of thermodynamics. This tradeoff for information acquisition may find applications in several areas of knowledge.

    Today's professionals are constantly striving to create sensor technology and systems with lower cost and higher efficiency. Miniaturization and standardization have become critical drivers for cost reduction in the design and development process, giving rise to a new era of smart sensors and actuators. These devices contain more components, but normally provide significant cost savings due to wider applicability and mass production. This first-of-its-kind resource presents methods for cost optimization of smart microsystems to help you select highly cost-efficient implementation variants. Wri

  4. Injecting Abstract Interpretations into Linear Cost Models

    Directory of Open Access Journals (Sweden)

    David Cachera

    2010-06-01

    Full Text Available We present a semantics based framework for analysing the quantitative behaviour of programs with regard to resource usage. We start from an operational semantics equipped with costs. The dioid structure of the set of costs allows for defining the quantitative semantics as a linear operator. We then present an abstraction technique inspired from abstract interpretation in order to effectively compute global cost information from the program. Abstraction has to take two distinct notions of order into account: the order on costs and the order on states. We show that our abstraction technique provides a correct approximation of the concrete cost computations.

    In the minimum cost spanning tree model we consider decentralized pricing rules, i.e. rules that cover at least the ecient cost while the price charged to each user only depends upon his own connection costs. We de ne a canonical pricing rule and provide two axiomatic characterizations. First......, the canonical pricing rule is the smallest among those that improve upon the Stand Alone bound, and are either superadditive or piece-wise linear in connection costs. Our second, direct characterization relies on two simple properties highlighting the special role of the source cost....

    The role and share of photovoltaic (PV) generated electricity in our nation`s future energy arsenal is primarily dependent on its future production cost. This paper provides a framework for obtaining a minimum achievable electrical generating cost (a lower bound) for fixed, flat-plate photovoltaic systems. A cost of 2.8 $cent/kWh (1990$) was derived for a plant located in Southwestern USA sunshine using a cost of money of 8%. In addition, a value of 22 $cent/Wp (1990$) was estimated as a minimum module manufacturing cost/price

    This report uses representative project types to estimate the levelized cost of wind energy (LCOE) in the United States for 2013. Scheduled to be published on an annual basis, it relies on both market and modeled data to maintain a current understanding of wind generation cost trends and drivers. It is intended to provide insight into current component-level costs and a basis for understanding current component-level costs and a basis for understanding variability in the LCOE across the industry. Data and tools developed from this analysis are used to inform wind technology cost projections, goals, and improvement opportunities.

    2008-01-01

    Intrusion Detection is an invaluable part of computer networks defense. An important consideration is the fact that raising false alarms carries a significantly lower cost than not detecting at- tacks. For this reason, we examine how cost-sensitive classification methods can be used in Intrusion Detection systems. The performance of the approach is evaluated under different experimental conditions, cost matrices and different classification models, in terms of expected cost, as well as detection and false alarm rates. We find that even under unfavourable conditions, cost-sensitive classification can improve performance significantly, if only slightly.

  13. Low-cost inertial measurement unit.

    2005-03-01

    Sandia National Laboratories performs many expensive tests using inertial measurement units (IMUs)--systems that use accelerometers, gyroscopes, and other sensors to measure flight dynamics in three dimensions. For the purpose of this report, the metrics used to evaluate an IMU are cost, size, performance, resolution, upgradeability and testing. The cost of a precision IMU is very high and can cost hundreds of thousands of dollars. Thus the goals and results of this project are as follows: (1) Examine the data flow in an IMU and determine a generic IMU design. (2) Discuss a high cost IMU implementation and its theoretically achievable results. (3) Discuss design modifications that would save money for suited applications. (4) Design and implement a low cost IMU and discuss its theoretically achievable results. (5) Test the low cost IMU and compare theoretical results with empirical results. (6) Construct a more streamlined printed circuit board design reducing noise, increasing capabilities, and constructing a self-contained unit. Using these results, we can compare a high cost IMU versus a low cost IMU using the metrics from above. Further, we can examine and suggest situations where a low cost IMU could be used instead of a high cost IMU for saving cost, size, or both.

    In 2009, they decided to update the Yellow Book, and began to update it by analyzing user experiences. They found that several countries have adopted the proposed standardized cost structure for the production of cost estimates directly or for mapping national estimates onto a common structure. They also made conclusions that more detailed advice should be given on the use of the standardized structure and on the definition of cost items to avoid ambiguity. The revised cost structure, to be known as the International Structure for Decommissioning Costing (ISDC), was published in 2012. The standardized cost structure developed in the report may be used for estimating the costs of decommissioning of any type of nuclear facility. We analyzed this standardized cost structure (ISDC) and applied it to DECOMMIS which was developed by KAERI. The appropriate estimation system for domestic application was examined by comparing the estimation results. KAERI made WBS code in DECOMMIS and data obtained during decommissioning work of KRR2 and UCP. Recently the IAEA updated the decommissioning cost items and its structure by ISDC. The cost estimation items of the DECOMMIS were applied to ISDC structure. For applying, the ISDC code compared with WBS code of DECOMMIS as on text of the activity name from daily report basis. The mapping result of the ISDC items to WBS code of the DECOMMIS is much different. AS results of this study that it need the corresponding cost category which classified in accordance with the national standard price estimates.

  16. Price-Transparency and Cost Accounting

    Directory of Open Access Journals (Sweden)

    Peter Hilsenrath PhD

    2015-04-01

    Full Text Available Health care reform is directed toward improving access and quality while containing costs. An essential part of this is improvement of pricing models to more accurately reflect the costs of providing care. Transparent prices that reflect costs are necessary to signal information to consumers and producers. This information is central in a consumer-driven marketplace. The rapid increase in high deductible insurance and other forms of cost sharing incentivizes the search for price information. The organizational ability to measure costs across a cycle of care is an integral component of creating value, and will play a greater role as reimbursements transition to episode-based care, value-based purchasing, and accountable care organization models. This article discusses use of activity-based costing (ABC to better measure the cost of health care. It describes examples of ABC in health care organizations and discusses impediments to adoption in the United States including cultural and institutional barriers.

    Product cost is one of the most important factors affectingproduct market share. Traditionally, product costs are estimated after they are manufactured. However, in this way, the best opportunity to control product cost is lost. In this paper, a method trying to reduce product cost at the design stage is proposed. This method is called Design to Cost (DTC). According to this method, product structure can be optimized with the application of value engineering and Design for Manufacturing/Assembly (DFMA) criteria in the conceptual stage of product design. During embodiment design, products are evaluated economically on the basis of the product model which includes manufacturing, assembly and test cost information. According to the results, products are redesigned before manufacture, and the production cost is reduced.

    2014-05-01

    The provision of guidelines on cost measurement for health economic evaluations enable research to be more standardized and hence more comparable, which offers clear benefits for policy formulation and health management. The guidelines herein focus on three aspects-the cost of health intervention/health care programs, the cost of illness/health risks, and use of costs in health economic evaluation. For each aspect, the main concepts and methods are outlined, and recommendations for the Thai context are presented. There is particular focus on how to calculate various costs according to different evaluation methods and perspectives, how to evaluate source of cost data, how to make value adjustments and how to present cost measurement findings.

    Full Text Available Abstract Background The cost-benefit of raccoon rabies control strategies such as oral rabies vaccination (ORV are under evaluation. As an initial quantification of the potential cost savings for a control program, the collection of selected rabies cost data was pilot tested for five counties in New York State (NYS in a three-year period. Methods Rabies costs reported to NYS from the study counties were computerized and linked to a human rabies exposure database. Consolidated costs by county and year were averaged and compared. Results Reported rabies-associated costs for all rabies variants totalled $2.1 million, for human rabies postexposure prophylaxes (PEP (90.9%, animal specimen preparation/shipment to laboratory (4.7%, and pet vaccination clinics (4.4%. The proportion that may be attributed to raccoon rabies control was 37% ($784,529. Average costs associated with the raccoon variant varied across counties from $440 to $1,885 per PEP, $14 to $44 per specimen, and $0.33 to $15 per pet vaccinated. Conclusion Rabies costs vary widely by county in New York State, and were associated with human population size and methods used by counties to estimate costs. Rabies cost variability must be considered in developing estimates of possible ORV-related cost savings. Costs of PEPs and specimen preparation/shipments, as well as the costs of pet vaccination provided by this study may be valuable for development of more realistic scenarios in economic modelling of ORV costs versus benefits.

    2006-05-01

    Full Text Available Abstract Background Insecticide-treated nets (ITNs are an effective and cost-effective means of malaria control. Scaling-up coverage of ITNs is challenging. It requires substantial resources and there are a number of strategies to choose from. Information on the cost of different strategies is still scarce. To guide the choice of a delivery strategy (or combination of strategies, reliable and standardized cost information for the different options is required. Methods The electronic online database PubMed was used for a systematic search of the published English literature on costing and economic evaluations of ITN distribution programmes. The keywords used were: net, bednet, insecticide, treated, ITN, cost, effectiveness, economic and evaluation. Identified papers were analysed to determine and evaluate the costing methods used. Methods were judged against existing standards of cost analysis to arrive at proposed standards for undertaking and presenting cost analyses. Results Cost estimates were often not readily comparable or could not be adjusted to a different context. This resulted from the wide range of methods applied and measures of output chosen. Most common shortcomings were the omission of certain costs and failure to adjust financial costs to generate economic costs. Generalisability was hampered by authors not reporting quantities and prices of resources separately and not examining the sensitivity of their results to variations in underlying assumptions. Conclusion The observed shortcomings have arisen despite the abundance of literature and guidelines on costing of health care interventions. This paper provides ITN specific recommendations in the hope that these will help to standardize future cost estimates.

    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.

    1996-03-31

    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.

    2014-01-01

    Full Text Available The objective of this paper is an effort to view the possibilities of integrated use of target costing, activity based costing and Kaizen concept in the internal value chain as the central link of the entire chain. The idea is to stimulate the company management to think about the costs, position they take in the structure of price cost and their influence on forming the sales price since it is very important to produce right product for the consumer, of desired quality and functionality but along with as low production costs as possible. It is therefore needed to construct the right design of a product and provide its production at the shortest possible time along with as low costs as possible which will impact the efficiency of the entire value chain.

    economical study shows that the total cost of the reinforced concrete section for the folded strip footings is less than the traditional one by about 18%. This difference in cost of both types of footings is mainly due to the relatively smaller in steel reinforcement ratio needed for the folded type as compared with the rectangular ones. So, the folded strip footing is more economical than the rectangular strip footing.

    Effective violence interventions are not widely implemented, and there is little information about the cost of violence interventions. Our goal is to report the cost of a brief intervention delivered in the emergency department that reduces violence among 14- to 18-year-olds. Primary outcomes were total costs of implementation and the cost per violent event or violence consequence averted. We used primary and secondary data sources to derive the costs to implement a brief motivational interviewing intervention and to identify the number of self-reported violent events (eg, severe peer aggression, peer victimization) or violence consequences averted. One-way and multi-way sensitivity analyses were performed. Total fixed and variable annual costs were estimated at $71,784. If implemented, 4208 violent events or consequences could be prevented, costing $17.06 per event or consequence averted. Multi-way sensitivity analysis accounting for variable intervention efficacy and different cost estimates resulted in a range of $3.63 to $54.96 per event or consequence averted. Our estimates show that the cost to prevent an episode of youth violence or its consequences is less than the cost of placing an intravenous line and should not present a significant barrier to implementation.

    There is a growing literature reporting the extent of transaction costs for environmental policies. However understanding why transaction costs occur and why they are small or large is also important for efficient policy selection and evaluation. Following an analysis of the organisational economics literature and reports of the extent of transaction costs for a number of environmental policies, three key influences to transaction costs in environmental policies are identified. These are the following: (1) the characteristics of the transaction for the environmental good; (2) the nature of the transactors; and (3) the current institutional environment and arrangements. These affect transaction costs to the government and all other parties influenced by a policy. Transaction costs occur due to actions of information collection and policy design, policy enactment and establishment, implementation and contracting, administration and monitoring, and enforcement. An interrogation of transaction cost influences reveals that: (1) the influence varies between parties and is affected by the actions and interactions of and between all parties to a policy; (2) how transaction costs are experienced varies across time; and (3) who experiences transaction costs depends on the policy itself. Future policy selection and refinement will benefit from empirical analysis of the causes of transaction costs. (author)

    Modern burn care is a resource intensive endeavor requiring specialized equipment, personnel, and facilities in order to provide optimum care. The costs associated with burn injury to both patients and society as a whole can be multifaceted and large. The purpose of this study was to evaluate the association between hospital costs, patient characteristics, and injury factors in a cohort of pediatric patients admitted to a regional burn center. We performed a review of the hospital charges accrued by pediatric patients (age dollar costs using an inflation index and a cost to charge ratio. Univariate and multivariate regressions were performed to identify the factors most significantly associated with cost. In addition, we performed a subset cost analysis for patients with burns more than 20% TBSA. A total of 1443 pediatric patients (age dollars was dollars 9026 (SD = dollars 25,483; median = dollars 2138). Area of full thickness burn was the only patient or injury factor significantly associated with greater hospital costs (P < .05) on multivariate analysis. No single anatomic area was associated with increased hospital costs when adjusted for total overall burn size. Injury severity was the most significant factor impacting index hospitalization costs following pediatric burn injury. Further studies defining the long-term societal costs impact of burn injury are needed as are studies that evaluate the impact of burn injury on quality of life.

    2008-01-01

    Ethical conflicts are a common phenomenon in today's healthcare settings. As healthcare executives focus on balancing quality care and cost containment, recognizing the costs associated with ethical conflicts is only logical. In this article, we present five case vignettes to identify several general cost categories related to ethical conflicts, including operational costs, legal costs, and marketing and public relations costs. In each of these cost categories, the associated direct, indirect, and long-term costs of the ethical conflict are explored as well. Our analysis suggests that organizations have, in addition to philosophical reasons, financial incentives to focus on decreasing the occurrence of ethical conflicts. The cost categories affected by ethical conflicts are not insignificant. Such conflicts can affect staff morale and lower the organization's overall culture and profit margin. Therefore, organizations should develop mechanisms and strategies for decreasing and possibly preventing ethical conflicts. The strategies suggested in this article seek to shift the organization's focus when dealing with conflicts, from just reacting to moving upstream-that is, understanding the root causes of ethical conflicts and employing approaches designed to reduce their occurrence and associated costs. Such an effort has the potential to enhance the organization's overall culture and ultimately lead to organizational success.

  1. Cost Contributors to Geothermal Power Production

    2011-07-01

    The US Department of Energy Geothermal Technologies Office (DOE-GTO) has developed the tool Geothermal Electricity Technologies Evaluation Model (GETEM) to assess the levelized cost of electricity (LCOE) of power produced from geothermal resources. Recently modifications to GETEM allow the DOE-GTO to better assess how different factors impact the generation costs, including initial project risk, time required to complete a development, and development size. The model characterizes the costs associated with project risk by including the costs to evaluate and drill those sites that are considered but not developed for commercial power generation, as well as to assign higher costs to finance those activities having more risk. This paper discusses how the important parameters impact the magnitude project costs for different project scenarios. The cost distributions presented include capital cost recovery for the exploration, confirmation, well field completion and power plant construction, as well as the operation and maintenance (O&M) costs. The paper will present these cost distributions for both EGS and hydrothermal resources.

    Full Text Available The complexity of the system design is increasing very rapidly as the number of transistors on Integrated Circuits (IC doubles as per Moore’s law.There is big challenge of testing this complex VLSI circuit, in which whole system is integrated into a single chip called System on Chip (SOC. Cost of testing the SOC is also increasing with complexity. Cost modeling plays a vital role in reduction of test cost and time to market. This paper includes the cost modeling of the SOC Module testing which contains both analog and digital modules. The various test cost parameters and equations are considered from the previous work. The mathematical relations are developed for cost modeling to test the SOC further cost modeling equations are modeled in Graphical User Interface (GUI in MATLAB, which can be used as a cost estimation tool. A case study is done to calculate the cost of the SOC testing due to Logic Built in Self Test (LBIST and Memory Built in Self Test (MBIST. VLSI Test engineers can take the benefits of such cost estimation tools for test planning.

  3. Vital truths about managing your costs.

    Science.gov (United States)

    Ames, B C; Hlavacek, J D

    1990-01-01

    Four truths apply to every business situation: 1. It is essential to be a lower cost supplier. 2. To stay competitive, inflation-adjusted costs of producing and supplying products and services must trend downward. 3. The true cost and profit pictures for each product/market segment must always be known, and traditional accounting practices must not obscure them. 4. A business must concentrate as much on cash flow and balance-sheet strengths as it does on profits. In order to ascertain exactly what your costs are, you must carefully isolate and assign various costs to specific products, accounts, or markets. Managers often do this badly, working on the basis of "average" costs. This ignores important differences among products and the fact that different products, different markets, and different customers incur different overhead costs. Most manufacturing companies' most important expense categories are R&D, sales, and general and administrative costs, but surprisingly, they generally don't get the attention they should. Neither do two crucial ratios-gross margin and the percent of assets employed per dollar of sales. Gross margins should usually not be less than 40%, and for most manufacturing companies, assets should not be over 60% of annual sales. Wrong deviation from these ratios will undermine profit targets. Once your costs are known and clearly assigned to product lines, markets, and key customers, they should be widely shared in the organization so that everyone will feel committed to cost management and know when deviations occur.

    Background Turnover rates in nursing homes have been persistently high for decades, ranging upwards of 100%. Objectives To estimate the net costs associated with turnover of direct care staff in nursing homes. Data and sample 902 nursing homes in California in 2005. Data included Medicaid cost reports, the Minimum Data Set (MDS), Medicare enrollment files, Census and Area Resource File (ARF). Research Design We estimated total cost functions, which included in addition to exogenous outputs and wages, the facility turnover rate. Instrumental variable (IV) limited information maximum likelihood techniques were used for estimation to deal with the endogeneity of turnover and costs. Results The cost functions exhibited the expected behavior, with initially increasing and then decreasing returns to scale. The ordinary least square estimate did not show a significant association between costs and turnover. The IV estimate of turnover costs was negative and significant (p=0.039). The marginal cost savings associated with a 10 percentage point increase in turnover for an average facility was $167,063 or 2.9% of annual total costs. Conclusion The net savings associated with turnover offer an explanation for the persistence of this phenomenon over the last decades, despite the many policy initiatives to reduce it. Future policy efforts need to recognize the complex relationship between turnover and costs. PMID:19648834

  6. Messaging with Cost-Optimized Interstellar Beacons

    On Earth, how would we build galactic-scale beacons to attract the attention of extraterrestrials, as some have suggested we should do? From the point of view of expense to a builder on Earth, experience shows an optimum trade-off. This emerges by minimizing the cost of producing a desired power density at long range, which determines the maximum range of detectability of a transmitted signal. We derive general relations for cost-optimal aperture and power. For linear dependence of capital cost on transmitter power and antenna area, minimum capital cost occurs when the cost is equally divided between antenna gain and radiated power. For nonlinear power-law dependence, a similar simple division occurs. This is validated in cost data for many systems; industry uses this cost optimum as a rule of thumb. Costs of pulsed cost-efficient transmitters are estimated from these relations by using current cost parameters (/W, /m2) as a basis. We show the scaling and give examples of such beacons. Galactic-scale beacons can be built for a few billion dollars with our present technology. Such beacons have narrow "searchlight" beams and short "dwell times" when the beacon would be seen by an alien observer in their sky. More-powerful beacons are more efficient and have economies of scale: cost scales only linearly with range R, not as R2, so number of stars radiated to iincreases as the square of cost. On a cost basis, they will likely transmit at higher microwave frequencies, ˜10 GHz. The natural corridor to broadcast is along the galactic radius or along the local spiral galactic arm we are in. A companion paper asks "If someone like us were to produce a beacon, how should we look for it?"

    To create and validate a micro-costing methodology that surgeons and hospital administrators can use to evaluate the cost of implementing innovative surgical technologies. Our analysis is broken down into several elements of fixed and variable costs which are used to effectively and easily calculate the cost of surgical operations. As an example of application, we use data from 86 robot assisted gastric bypass operations made in our hospital. To validate our methodology, we discuss the cost reporting approaches used in 16 surgical publications with respect to 7 predefined criteria. Four formulas are created which allow users to import data from their health system or particular situation and derive the total cost. We have established that the robotic surgical system represents 97.53 % of our operating room's medical device costs which amounts to $4320.11. With a mean surgery time of 303 min, personnel cost per operation amounts to $1244.73, whereas reusable instruments and disposable costs are, respectively, $1539.69 and $3629.55 per case. The literature survey demonstrates that the cost of surgery is rarely reported or emphasized, and authors who do cover this concept do so with variable methodologies which make their findings difficult to interpret. Using a micro-costing methodology, it is possible to identify the cost of any new surgical procedure/technology using formulas that can be adapted to a variety of operations and healthcare systems. We hope that this paper will provide guidance for decision makers and a means for surgeons to harmonise cost reporting in the literature.

Costs of pulsed cost-efficient transmitters are estimated from these relations by using current cost parameters ($/W, $/sq m) as a basis. We show the scaling and give examples of such beacons. Galactic-scale beacons can be built for a few billion dollars with our present technology. Such beacons have narrow "searchlight" beams and short "dwell times" when the beacon would be seen by an alien observer in their sky. More-powerful beacons are more efficient and have economies of scale: cost scales only linearly with range R, not as R(exp 2), so number of stars radiated to increases as the square of cost. On a cost basis, they will likely transmit at higher microwave frequencies, -10 GHz. The natural corridor to broadcast is along the galactic radius or along the local spiral galactic arm we are in. A companion paper asks "If someone like us were to produce a beacon, how should we look for it?"

  9. Energy economics can be costly

    According to A. Cluer (Inst. Pet.) at the Eurochem 80 conference (Birm. June 1980), the available reserves of conventional crude oil are, or will soon be, at their peak. The Middle East has 57% of the 88,000 Mtons of crude oil known to exist, about a 30 yr supply at current production rates. Uncertain supplies and an OPEC market price of about $35/bbl can only stimulate the development of synthetic oil production from coal and other hydrocarbon sources, although this will be hindered by environmental problems, large investments, and the long lead times needed, a view shared by J. Solbett (Humphreys and Glasgow Ltd.) at the conference. Both speakers agreed that the use of oil for transport and chemical feeds, for which oil is ideally suited, is the least amenable area for substitution by synthetic fuels; and that it is therefore important that general energy requirements be satisfied by alternatives such as coal and nuclear power. Cluer cited OECD statistics which show that implementing minimum energy efficiency standards could cut by 35% transport energy consumption, by 1985. Comments by T. Kantyka (ICI) on the cost effectiveness of energy conservation are also discussed.

    The Worldwide LHC Computing Grid project (WLCG) provides the computing and storage resources required by the LHC collaborations to store, process and analyse the 50 Petabytes of data annually generated by the LHC. The WLCG operations are coordinated by a distributed team of managers and experts and performed by people at all participating sites and from all the experiments. Several improvements in the WLCG infrastructure have been implemented during the first long LHC shutdown to prepare for the increasing needs of the experiments during Run2 and beyond. However, constraints in funding will affect not only the computing resources but also the available effort for operations. This paper presents the results of a detailed investigation on the allocation of the effort in the different areas of WLCG operations, identifies the most important sources of inefficiency and proposes viable strategies for optimising the operational cost, taking into account the current trends in the evolution of the computing infrastructure and the computing models of the experiments.

    Full Text Available In the literature there are many approaches regarding the notion of cost and expense. The approaches are varied and complex. Very often both expressions are used as synonyms, or in the definition of expenses and cost appear. It should be clarified what is the connection between the two. Which was born first, cost or expense? The cost is very clearly tied to the production of tangible and intangible assets and the default cost accounting (managerial accounting and expense relates to incomes and hence of financial accounting. In my understanding the cost is preceding expense. It is imperative to clarify these issues both theoretically and practically. I decided to clarify these issues in this article, as it fallows.

  13. Activity based costing the performance breakthrough

    1996-01-01

    Activity-based costing is a method of measuring the cost and performance of activities, products and customers. It is increasingly being seen as a more accurate method of costing than conventional costing systems, which are being superseded by the fact that automation means that direct material and labour consumption is now a far less accurate means of apportioning overheads. This practical book outlines why conventional cost systems fail, before going on to cover the advantages of activity-based costing, and describing how to put the system in place successfully, and how to apply the lessons learnt quickly. The book takes the reader step-by-step through the various processes involved, from setting up the system, through its operation, to evaluation of the results.

    Full Text Available This paper attempts to integrate Value Stream Map (VSM with the cost aspects. A value stream map provides a blueprint for implementing lean manufacturing concepts by illustrating information and materials flow in a value stream. The objective of the present work is to integrate the various cost aspects. The idea is to introduce a cost line, which enhances the clarity in decision making. The redesigned map proves to be effective in highlighting the improvement areas, in terms of quantitative data. TAKT time calculation is carried out to set the pace of production. Target cost is set as a bench mark for product cost. The results of the study indicates that implementing VSM led to reduction in the following areas: processing lead time by 34%, processing cycle time was reduced by 35%, Inventory level by 66% and product cost from Rs 137 to Rs 125. It was found that adopting VSM in a small scale industry can make significant improvements.

    of the results was nutrient reduction targets for each country - the BSAP targets. Because the Baltic Sea is such an international marine area, receiving pollutants from many  countries, an international approach is necessary to make effective solutions. But is the BSAP the most cost-effective solution...... to the regulation of the Baltic Sea? And does the BSAP result in cost-effective reductions in the different countries, which is a requirement of the Water Framework Directive and the Marine Strategy Directive?   These questions are studied and answered using a cost minimisation model for the Baltic sea, initially...... the BSAP targets are set as target reductions for each countries.  The comparison reveals what the additional costs of fulfilling a political target for each country are instead pursuing a cost effective solution for the Baltic Sea.  In addition  we simulate cost minimising solutions for obtaining...

    The Danish National Archives, and The Royal Library and the State and University Library are in the process of developing a cost model for digital preservation: Each of the functional entities of the OAIS Reference Model are broken down into measurable, cost-critical activities, and formula...... are being tailored for each of these in order to create a generic tool for estimating the short and long-term costs of digital preservation. This paper presents an introduction to the subject of the costs of digital preservation and describes the method used to develop the Danish Cost Model for Digital...... Preservation (CMDP). It then describes how the OAIS functional entity, Ingest, has been included in the model. For institutions basing their digital preservation strategy on migration, a major cost pertaining to Ingest is normalization, a digital migration from production to preservation format and structure...

    In a population-based study of dementia, the cost of care for 245 demented elderly and 490 controls matched by age and gender was estimated. Dementia of Alzheimer's type was diagnosed according to the NINCDS-ADRDA criteria, and vascular dementia and other types of dementia were diagnosed according...... to the DSM-IIIR criteria. Severity of dementia was determined by the Clinical Dementia Rating scale. The annual cost of medical care, domestic care, home help, nursing home and special equipment for nondemented patients was DKK 22,000 per person while the cost for very mildly, mildly, moderately and severely...... demented patients was DKK 49,000, DKK 93,000, DKK 138,000 and DKK 206,000, respectively. Except for very mild dementia the cost did not differ between elderly who suffer from Alzheimer's disease and those with other types of dementia. The net cost of dementia is the difference in cost between those...

    We analyzed the costs to a hospital of providing complete home parenteral nutrition (HPN) services for eight patients. Identified cost components include patient training, equipment, supplies, and follow-up. The average annual cost of maintaining parenteral nutrition at home was 73% lower than it would have been in the hospital. The establishment of private companies to provide patients with HPN supplies and services will reduce the financial burden of HPN programs for hospitals.

    Full Text Available Progress in improving production technology requires appropriate measures to achieve an efficient management of costs. This raises the need for continuous improvement of management accounting and cost calculation. Accounting information in general, and management accounting information in particular, have gained importance in the current economic conditions, which are characterized by risk and uncertainty. The future development of management accounting and cost calculation is essential to meet the information needs of management.

  20. Local matching indicators for concave transport costs

    Delon, Julie; Sobolevskii, A

    2009-01-01

    In this note, we introduce a class of indicators that enable to compute efficiently optimal transport plans associated to arbitrary distributions of $N$ demands and $N$ supplies in $\\mathbf{R}$ in the case where the cost function is concave. The cost of these indicators is small and independent of $N$. Using them recursively according to a particular algorithm allows to find an optimal transport plan in less than $N^2$ evaluations of the cost function.
